Today, I will introduce a national invention authorized patent - an intelligent anti-flip water meter. The patent was applied for by Zhuhai Dingtong Technology Co., Ltd. and the authorization announcement was issued on November 2, 2018.
Content descriptionThe invention relates to the technical field of water meters, in particular to an intelligent anti-flip-mounted water meter.
Background of the InventionDuring the installation and use of the water meter, installation errors often occur. The inlet and outlet of the water meter are installed in the opposite direction, or the water meter is artificially installed upside down, resulting in the inability of the water meter to measure correctly. Generally, the smart water meter cannot automatically recognize the inversion situation, which brings inconvenience to users and water companies. and economic losses. Usually, the way to prevent the reverse installation of the water meter is to install a check valve at the outlet of the water meter, but it is unavoidable to remove the check valve intentionally or unintentionally when installing the water meter.
SUMMARY OF THE INVENTIONIn order to overcome the above-mentioned deficiencies of the prior art, the present invention provides an intelligent anti-flip-mounted water meter with a simple structure, which can accurately identify the inversion and automatically control the valve closing.
The technical solution adopted by the present invention to solve the technical problem is as follows: an intelligent anti-flip water meter, comprising a meter body, an execution group for switching the meter body, a detection group for detecting the flow direction of a water body, and a control group, the meter body There are water inlet joints and water outlet joints on it. The detection group includes a fairing, a bracket arranged at the water outlet end of the fairing, a watch rotor that can be driven by the water flow and is rotatably installed between the fairing and the bracket, and is arranged on the watch movement. The magnetic block on the rotor and the sampling head for collecting the rotation signal of the magnetic block, the water inlet joint locks the fairing in the meter body, the execution group is connected between the bracket and the water outlet joint, and the sampling head is provided with At least two groups, each group of sampling heads are arranged on one side of the bracket, and the sensing point is located on the side close to the magnetic block, the sampling heads can send sensing signals to the control group, and the control group can control the execution group to switch the meter body.
As an improvement of the above technical solution, the magnetic block is installed on the water outlet end of the watch core rotor, and the sensing point of the sampling head is directly opposite to the magnetic block. As an improvement of the above technical solution, the meter body is provided with an installation hole, the sampling head is screwed into the installation hole, and the upper end of the installation hole is sealed by a screw cap. As an improvement of the above technical solution, the execution group includes a ball valve, a joystick and an actuator, the ball valve is arranged between the bracket and the water outlet joint, and the water outlet joint locks the ball valve in the watch body, and the joystick can be rotated through the body. It is arranged on the watch body, the actuator is installed outside the watch body, one end of the joystick is connected with the ball valve, and the other end is connected with the output end of the actuator.
As an improvement of the above-mentioned technical solution, the outer cover of the joystick is provided with a protective cover, and the protective cover is installed on the watch body. As an improvement of the above technical solution, the control group includes a control board and a display mounted on the control board, the control board is installed on the meter body, and the control board exchanges data with the sampling head and the execution group. As an improvement of the above technical solution, the control group is further provided with a battery, and the battery provides electrical energy for the control board. As an improvement of the above technical solution, the watch body is provided with a protective case outside the control group, and the protective case is provided with an observation window at the position of the display.
The beneficial effects of the invention are as follows: the intelligent anti-flip-mounted water meter is provided with a detection group in the meter body, and the watch core rotor in the detection group is used to rotate according to the flow of water, and the magnetic block on the watch core rotor is driven to rotate. The polarities of the magnetic blocks are different. The rotating magnetic blocks are used to realize the change of the magnetic field lines, and then the inductive elements inside the sampling head are used to receive these magnetic field lines, thereby generating the opening and closing pulse signals. Due to the inconsistent installation direction of the water meter , the direction of water flow is also different, so that the order of feedback signals of multiple groups of sampling heads is also different. The control group judges the installation direction of the water meter according to the order of the feedback signals, and the control group then controls the execution group to automatically open and close the water meter. The entire meter body structure Simple, easy to implement, convenient control process, realize automatic control of water meter, and achieve the effect of anti-reverse installation of water meter.
