[0032] Embodiment 1:
[0033] Reference Figure 1-7 A switch final detection device for a ship lock miter gate suitable for large-scale open-tooth transmission, comprising a bottom plate 1, which is fixed to the top of a connecting plate 11 on the AB pull rod 10 of the miter gate through a general bracket 7 at the bottom end; two groups of bases 2 are fixed to the middle part of the top of the bottom plate 1, and a protective cover 6 for covering the base 2 is fixed to the periphery of the base 2 and located on the top of the bottom plate 1; a base plate 8 is fixed to the top of the door body 12 on the opposite side of the bottom plate 1; a proximity switch mounting piece 4 is installed on the top of each group of bases 2 through a slide 3, and each group of proximity switch mounting pieces 4 is respectively installed with a proximity switch 5, and two groups of targets 9 for detection by the proximity switch 5 are installed above the base plate 8. By adopting the above-mentioned detection device, the open and closed final positions of the miter gate can be reliably detected, the probability of the final failure of the miter gate switch is effectively reduced, and the time for adjusting the final detection device of the miter gate switch is shortened; after adopting the optimization device, by monitoring the operating status, the position of the miter gate is within the normal range when the miter gate switch is finally opened and closed, and the sensor works stably, which fully ensures the safe and efficient operation of the miter gate.
[0034] Furthermore, the bottom plate 1 is drilled with a plurality of positioning through holes 101, and the bottom of the base 2 is fixedly connected to the bottom plate 1 by penetrating the positioning through holes 101. By adopting the positioning through holes 101, the initial positioning connection between the bottom plate 1 and the base 2 can be achieved, ensuring the rapidity of adjusting the position of the base 2 to a large extent.
[0035] Furthermore, the protective cover 6 is provided with a wiring groove 601 and a limiting groove 602. The limiting groove 602 is used for positioning and assembling the protective cover 6 and the main bracket 7. The wiring groove 601 can guide the electrical circuit in the device to the outside, thereby improving the aesthetics of the device. The limiting groove 602 can accurately position the protective cover 6 on the main bracket 7, thereby ensuring the convenience of disassembling the protective cover to adjust the device.
[0036] Furthermore, the main bracket 7 includes a bracket 701 and a fixing screw 702 for fixing with the connecting plate 11, and the lower part of the bracket 701 is fixedly connected with the fixing screw 702 by a screw passing through a through hole 703. The main bracket 7 can be reliably fixed to the top of the connecting plate on the AB pull rod of the miter gate through the bracket 701, thereby ensuring the reliability of the fixing.
[0037] Furthermore, the proximity switch mounting plate 4 is slidably mounted on the top of the slide 3 and is used to finely adjust the distance between the proximity switch 5 and the target 9. Through the above-mentioned mounting adjustment structure, it is ensured that the mounting position of the proximity switch 5 can be conveniently adjusted to adapt to different detection positions and detection accuracy requirements, thereby improving the detection accuracy.
[0038] Further, the proximity switch 5 includes a door closing proximity switch 501 and a door opening proximity switch 502, and the door closing proximity switch 501 and the door opening proximity switch 502 are respectively installed on two groups of bases 2. The door closing proximity switch 501 and the door opening proximity switch 502 can respectively realize the detection requirements of the door body closing and opening.
[0039] Furthermore, the target 9 includes a door closing detection target 901 and a door opening detection target 902, which are respectively arranged and installed on the top edge of the substrate 8 and located on the same circumference of the door body shaft. The above-mentioned target 9 can be used to cooperate with the proximity switch 5 to realize the closing and opening end point determination of the door body.
[0040] Furthermore, the door closing detection target 901 receives the signal of the door closing proximity switch 501 in the proximity switch 5 and feeds back the door closing position signal.

[0042] Embodiment 2:
[0043] See also Figure 1 The newly designed proximity switch 5 is installed on the slide 3 through the proximity switch mounting piece 4. When the relative position of the proximity switch 5 and the target 9 in the final state of the miter gate switch changes due to external factors, the relative position of the proximity switch 5 and the target 9 can be quickly adjusted through the slide 3, saving maintenance time, and the adjustment positioning accuracy is high, and it can be accurately adjusted to the required position. After the optimization device is adopted, it can be used for a long time without maintenance, ensuring the stability of the detection device.
[0044] See also Figure 2 , due to the harsh working environment of the switch terminal detection device operating in a large high-head single-stage ship lock, according to the environment of the proximity switch, the equipment needs to have certain rain protection and anti-collision functions. Considering that the detection device is installed outdoors, it is necessary to ensure that the detection device works stably and is resistant to rain corrosion. The sensor and the target are on the two moving gates. At this time, if the size of the detection device is wider than the size of the gate, there is a risk of collision with the ship moving in the lock chamber. Therefore, the design device must be small and not protrude from the gate.
[0045] The specific working process and principle of the device of the utility model are as follows:
[0046] When the miter gate is about to reach the final state of the switch, the proximity switch sends a signal to stop the opening and closing machine of the miter gate, and the miter gate stops at the specified position. That is to say, the relative distance between the proximity switch and the target does not change when the switch is about to end, and the miter gate can stop at the specified position every time.
