[0001] This utility model relates to the field of gate control technology, specifically to an automatic opening and closing control device for hydraulic gates. Background Technology

[0002] Hydraulic gates are important water conservancy facilities used to control water flow. They are widely used in reservoirs, rivers, irrigation canals and other scenarios. The opening and closing of traditional hydraulic gates is generally achieved through the cooperation of structures such as motors and screws.

[0003] However, due to the relatively humid environment in water conservancy projects, the control devices are exposed to moisture, dust and other elements for a long time. Their internal gears, motors and other components are prone to corrosion or malfunction, which can cause the gates to fail to open and close. This not only affects the normal operation of water conservancy projects, but also increases maintenance costs and safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic opening and closing control device for hydraulic gates to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic opening and closing control device for a hydraulic gate, comprising a gate and a control mechanism, wherein the control mechanism is installed at the upper end of the gate and the control mechanism can control the opening and closing of the gate;

[0006] The control mechanism is covered by a protective mechanism, which includes a housing, a clearance hole, an insertion tube, a cap, and a desiccant.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] In this technical solution, an automatic opening and closing control device for a hydraulic gate includes a gate 1 and a control mechanism 2. The control mechanism 2 is installed at the upper end of the gate 1 and can control the opening and closing of the gate 1.

[0022] The outer side of the control mechanism 2 is covered by a protective mechanism 3. The protective mechanism 3 includes a cover 31, a clearance hole 32, an insertion tube 33, a cap 34, and a desiccant 35. The cover 31 covers the outer side of the control mechanism 2. A clearance hole 32 is provided on the top of the cover 31. An insertion tube 33 is inserted into the side wall of the cover 31. The insertion tube 33 is filled with desiccant 35. The end of the insertion tube 33 located on the outside of the cover 31 is fastened with a cap 34. A sealing gasket 4 is sleeved on the outside of the insertion tube 33. The sealing gasket 4 is in contact with the side wall of the cover 31.

[0023] In this technical solution, the cover 31 can be attached to the outside of the control mechanism 2 to form physical protection, isolating most of the external moisture, dust and debris. The clearance hole 32 is set to allow the screw 21 in the control mechanism 2 to pass through the top of the cover 31, so that the upper part of the screw 21 can pass through the top of the cover 31, and avoid affecting the movement of the screw 21 when the gate 1 is lifted. The desiccant 35 in the insertion tube 33 can continuously absorb the moisture inside the cover 31, reduce the humidity inside the cover 31, thereby preventing the control mechanism 2 from rusting and affecting the opening and closing of the gate 1. The cover 34 can be opened regularly to replace the desiccant 35. In this paper, the desiccant 35 is montmorillonite desiccant. At the same time, the part of the insertion tube 33 located inside the cover 31 is a breathable cloth bag, which on the one hand prevents the desiccant 35 from scattering, and on the other hand does not affect the absorption of moisture by the desiccant 35. At the same time, the desiccant 35 in the insertion tube 33 needs to be replaced regularly to ensure the moisture absorption effect.

[0024] In some technical solutions, the control mechanism 2 includes a screw 21, a threaded sleeve 22, a first gear 23, a second gear 24, and a motor 25. The lower end of the screw 21 is installed above the gate plate of the gate 1. The upper end of the gate 1 is rotatably equipped with the threaded sleeve 22, which is rotated and installed on the outside of the screw 21. The outer wall of the threaded sleeve 22 is equipped with the first gear 23. The upper wall of the gate 1 is equipped with the motor 25, which is connected to an external power supply and a controller. The output end of the motor 25 is equipped with the second gear 24, which meshes with the first gear 23.

[0025] In this technical solution, the motor 25 can be controlled by an external controller to drive the second gear 24 to rotate. The meshing of the second gear 24 with the first gear 23 drives the threaded sleeve 22 to rotate. Since the threaded sleeve 22 and the screw 21 are connected by threads, the rotation of the threaded sleeve 22 is converted into the linear lifting motion of the screw 21, which in turn drives the gate plate of the gate 1 to move up and down, thereby realizing the automatic opening and closing control of the gate 1.

[0026] In some technical solutions, a fixed seat 5 is installed above the gate plate of the gate 1, a fixed cylinder 6 is installed on the upper wall of the fixed seat 5, the screw 21 is fixedly installed inside the fixed cylinder 6, and reinforcing ribs 7 are installed on both the left and right side walls of the fixed cylinder 6. The reinforcing ribs 7 are welded to the upper wall of the fixed seat 5.

[0027] In this technical solution, the fixed seat 5 is welded to the gate plate of the gate 1, while the fixed cylinder 6 is welded to the fixed seat 5, and the screw 21 is welded inside the fixed cylinder 6. The screw 21 cannot be rotated.

[0028] In some technical solutions, a bellows 8 is sleeved on the outside of the screw 21. The upper end of the bellows 8 is fitted and connected to the inner wall of the gate 1, and the lower end of the bellows 8 is fitted and connected to the upper wall of the fixed cylinder 6.

[0029] In this technical solution, the bellows 8 can expand and contract with the opening and closing of the gate 1. It wraps around the outside of the screw 21 and can effectively prevent impurities such as mud, sand and water vapor from directly contacting the threaded surface of the screw 21, thus avoiding wear or corrosion of the threads and extending the service life of the control mechanism 2. At the same time, the part of the screw 21 that protrudes from the cover 31 is also provided with a bellows 8, and the upper end of this part of the bellows 8 is provided with a plug to prevent water vapor from entering.

[0030] In some technical solutions, a water level monitor 9 is installed on the upper side wall of the gate 1, and the water level monitor 9 is connected to an external power source.

[0031] In this technical solution, the water level monitor 9 can monitor the water level of the environment where the gate 1 is located in real time, and convert the monitored water level signal into an electrical signal and transmit it to the controller; the controller automatically determines whether the gate 1 needs to be opened or closed according to the preset water level threshold, and provides a trigger signal for the action of the control mechanism 2, so as to realize the intelligent automatic control of the gate 1.

[0032] In some technical solutions, a dropper 10 is inserted and installed on the upper wall of the cover 31, and a block 11 is inserted and installed at one end of the dropper 10 located on the outside of the cover 31.

[0033] In this technical solution, the lower end of the dropper 10 corresponds to the meshing part of the gear in the control mechanism 2. After opening the plug 11, lubricating oil can be precisely added to the meshing part of the gear through the dropper 10 to reduce friction and wear during gear transmission. When not adding oil, the plug 11 seals the port of the dropper 10 to prevent external dust and moisture from entering the inside of the cover 31 through the dropper 10, thus ensuring a clean environment for the control mechanism 2.

[0034] Working principle: When the water level monitor 9 detects that the water level has reached the preset threshold, it transmits the signal to the controller, and the controller starts the motor 25. The motor 25 drives the second gear 24 to rotate, and through gear meshing, it drives the first gear 23 and the threaded sleeve 22 to rotate. The threaded engagement between the threaded sleeve 22 and the screw 21 causes the screw 21 to drive the gate plate of the gate 1 to rise and fall, thereby realizing the automatic opening and closing of the gate 1. The cover 31 of the protective mechanism 3 can isolate external impurities, and the desiccant 35 maintains a low humidity environment inside, thereby preventing the first gear 23 and the second gear 24 from rusting and affecting the opening and closing of the gate 1. When it is necessary to replace the desiccant 25, the insertion tube 33 can be pulled out directly, and the cover 34 can be opened to replace the desiccant 35.
