Description

Technical Field

[0001] The invention relates to the technical field of underwater stroke monitoring devices for flush valves, and in particular to an underwater stroke monitoring device for gate flush valves with wireless power supply. Background Art

[0002] When a flat gate is opened, it is necessary to perform flushing operations first. When the water levels before and after the gate are the same or nearly the same, the gate is allowed to open. When the gate falls to the bottom sill, it is necessary to ensure that the flushing valve is closed to end the gate opening and closing operations.

[0003] In the prior art, the gate works underwater, and the acquisition of its opening information completely depends on the stroke encoder installed on the gate hoist. The principle is to indirectly obtain the gate opening information through the reading of the stroke encoder. For gates with larger strokes, since the wire rope connecting the gate hoist and the gate is made of flexible material, there is a large error in the gate opening information indirectly obtained by relying on the encoder on the gate hoist. As a component of the gate, the total stroke of the flush valve is about 1% of the gate stroke. If the encoder on the gate hoist is continued to be used to obtain the stroke information of the flush valve, it is obviously unrealistic. In addition, since the stroke detection device of the gate hoist-gate system cannot accurately obtain the underwater position information of the flush valve, various accidents occur. Summary of the invention

[0031] In the present invention, the wireless power supply unit 62 includes a power supply unit shell 621, on which a power supply unit coil 622, a power supply unit control module 623 and a power supply wireless communication module 624 are fixedly installed, and a power detector 625 is fixedly installed on the power supply unit control module 623. The wireless power supply unit 62 is formed through the power supply unit coil 622 and power is emitted in the form of microwaves of a fixed frequency.

[0032] In the present invention, the wireless power receiving unit 63 includes a power receiving unit housing 631, on which a power receiving unit coil 632, a power receiving unit control module 633 and a power receiving wireless communication module 634 are fixedly installed.

[0036] Working principle of the present invention:

[0037] When the gate 2 enters the gate slot 1 and falls to the bottom sill, the wireless power supply unit 62 and the wireless power receiving unit 63 are on the same central axis. At this time, through the underwater wireless power transmission system, the wireless power supply unit 62 can transmit power from the power supply to the wireless power receiving unit 63. After the wireless power receiving unit 63 obtains power, it transmits the power to the rechargeable battery 654 in the detection unit 65 through the connecting wire 64. After the rechargeable battery 654 in the detection unit 65 is powered, it supplies power to the detection unit 65. The Hall device array 655 in the detection unit 65 transmits the information of whether there is a magnetic field nearby to the microcontroller 652 through the serial register 653; the eddy current sensor 657 transmits the obtained position information to the microcontroller 652, and the microcontroller 652 processes the information and transmits it to the power receiving wireless communication module 634 in the wireless power receiving unit 63 through the connecting wire 64. The power receiving wireless communication module 634 transmits the information to the power supply wireless communication module 624 through wireless transmission, and the power supply wireless communication module 624 transmits the information to the power supply wireless communication module 624 through the connecting wire 61 The information is transmitted to the host computer. When the flush valve is opened for flushing or closed, the movement of the movable shaft 3 will drive the permanent magnetic cursor 66 to move up and down. The Hall device array 655 in the detection unit 65 will continuously monitor the position of the permanent magnet 662, thereby obtaining the position of the movable shaft 3, and thus obtaining the real-time opening of the flush valve. When the permanent magnetic cursor 66 driven by the movable shaft 3 is close to the upper limit or the lower limit, the eddy current sensor 657 in the detection unit 65 can detect the precise position of the upper end face or the lower end face of the permanent magnetic cursor fixing seat 661, thereby determining the precise position of the flush valve at the upper or lower limit position, and finally determining whether the flush valve is fully opened or closed. After obtaining the real-time position of the flush valve, the detection unit 65 can transmit the information to the power receiving wireless communication module 634 in real time by wired means. The power receiving wireless communication module 634 transmits the information to the power supply wireless communication module 624 by underwater wireless means. The power supply wireless communication module 624 transmits the obtained flush valve opening information to the host computer by wired means. At this point, the host computer can obtain the opening information of the flush valve in real time.
