Description
Technical Field
[0001] The utility model relates to the technical field of gates, in particular to a replaceable gate water filling valve opening and gate position monitoring device. Background Art
[0002] In current life, for a flat gate with a pressure-equalizing water filling function, when opening the gate, the gate hoist needs to perform a lifting operation with a certain opening, so that the water filling valve is opened without opening the gate. The gate can be opened only after the water filling operation is completed. When closing the gate, the gate needs to be dropped to the bottom threshold and then the closing operation is continued until the water filling valve is closed.
[0003] For low-lift gate hoist systems, the gate opening and water filling valve position can be monitored by using a gate hoist stroke detection device to monitor the length of the gate hoist's retracted and released wire rope. However, for high-lift gate hoist systems, this method obviously has great limitations. It is precisely because of the lack of high-precision monitoring methods for the gate water filling valve position that accidents of varying sizes are often seen in China due to the inability to obtain the accurate position of the water filling valve. This problem needs to be solved urgently. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a replaceable gate water filling valve opening and gate position monitoring device. By setting a first sliding contact component and a second sliding contact component to slide on the surface of the outer shell cover, the absolute opening value of the gate and the distance change value between the gate and the water filling valve are obtained, and the opening and closing size of the water filling valve inside the gate body is calculated, thereby solving the problems mentioned in the background technology.
[0005] In order to solve the above problems, the utility model provides a technical solution:

[0009] As a preferred solution of the utility model, a straight plate is fixedly installed on the side of the retaining wall, a slide groove is opened inside the straight plate, and the replaceable sensing component is slidably sleeved inside the slide groove.
[0010] As a preferred solution of the utility model, the upper end of the replaceable sensing component is fixedly connected with a pipeline component, and the pipeline component is inserted into the surface of the C-shaped seat.
[0011] As a preferred solution of the utility model, the pipeline assembly includes a threaded pipe head, one end of which is fixedly installed on the top of the sensing housing, the outer surface of the threaded pipe head is threadedly connected to a pipe joint, the inner surface of the pipe joint is threadedly connected to a threading tube, and the interior of the sensing housing is connected to the threading tube through the threaded pipe head.

[0015] The beneficial effects of the utility model are:
[0016] 1.

Since the water filling valve lifting lug and the water filling valve body as well as the gate lifting lug and the gate body are rigid structures.

When replacing, only one diver is needed to guide the direction and align the position to complete the reassembly of the induction component, reducing maintenance time.

[0036] Embodiment 2:
[0037] In summary, when using the present device, firstly, the gate body 1 is placed inside the gate channel through the lifting device. When it is necessary to observe whether the gate body 1 has reached the bottom, the permanent magnet 63 at one end of the second sliding contact component 19 installed on the gate lifting ear 3 contacts the sensing housing 10. When the permanent magnet 63 at one end of the second sliding contact component 19 contacts the sensing housing 10, the position of the second sliding contact component 19 is sensed by the circuit board array inside the replaceable sensing component 21, and then the position of the gate body 1 is obtained by calculation, so as to judge whether the gate body 1 has reached the bottom and is completely closed. The lifting point continues to fall so that the water filling valve 18 falls from the inside of the gate lifting ear 3 on the gate body 1. At this time, the closing operation of the water filling valve starts. At this time, the permanent magnet 63 at one end of the second sliding contact component 19 contacts the sensing housing 10. The installed first sliding contact component 6 slides on the surface of the sensing housing 10 to determine whether the water filling valve 18 is fully closed. The permanent magnet 63 at one end of the first sliding contact component 6 is transmitted to the circuit board array through magnetic force, and then the vertical distance between the two permanent magnets 63 in the two sliding contact components is calculated through the circuit board array, so as to determine whether the water filling valve 18 is fully closed. When it is necessary to open the gate, the hoisting point of the gate opening machine is lifted, first driving the water filling valve 18 to lift, and then the first sliding contact component 6 on the water filling valve 18 slides on the side of the sensing housing 10. At this time, the permanent magnet 63 inside the first sliding contact component 6 is transmitted to the circuit board array through magnetic force, and the vertical distance between the two permanent magnets 63 in the two sliding contact components is calculated, so as to know the opening size of the water filling valve 18.
