[0002] Water conservancy and hydropower engineering mainly studies the basic knowledge and skills of water resources, hydraulic structures, hydraulics and fluid dynamics, and water conservancy engineering technology, and conducts survey, planning, design, construction, and management of water conservancy and hydropower engineering;

[0003] In the prior art, during the construction of water conservancy projects, it is necessary to build gates in the river channel. The gates are used to close and open the discharge (release) channel. They are an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. However, during the use of existing gates, since they are exposed to the outdoors, they will be eroded by rain and exposed to the sun for a long time. As a result, the screws for manually opening and closing the gates are easily dried and rusted, which makes it very difficult for the staff to open the gates. In addition, many gates are located in remote areas and are difficult to maintain at ordinary times. Therefore, we propose a water conservancy opening and closing gate. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. During the construction of water conservancy projects, it is necessary to build gates in the river channel. The gates are used to close and open the discharge (release) channel. They are important components of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. However, during the use of existing gates, since they are exposed to the outdoors, they will be eroded by rain and exposed to the sun for a long time. In this way, the screw for manually opening and closing the gates is easily dried and rusted, which makes it very difficult for the staff to open the gates. In addition, many gates are located in remote areas, and it is also very difficult to maintain them at ordinary times.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A water conservancy opening and closing gate comprises a trapezoidal weir and a gate plate located on the inner side of the weir, strip-shaped slide grooves are correspondingly provided on both sides of the gate plate and on the inner side of the weir, and the gate plate is slidably connected to the slide grooves, a round roller-shaped screw is vertically provided on the top of the gate plate, and the screw passes through the top of the weir and extends upward, a cylindrical oil storage tank is installed directly above the screw, and a cylindrical dropper is connected to the bottom of the oil storage tank, and a triangular sunshade and rain shield is installed above the oil storage tank, and the size of the sunshade and rain shield can be customized as needed.

[0007] As a preferred solution of the utility model, a connecting piece is symmetrically installed on the periphery of the screw near the bottom and located on the top of the gate plate, and connecting rollers penetrating the connecting piece are fixedly connected to both sides of the bottom of the connecting piece.

[0008] As a preferred solution of the utility model, a gate hoist base is installed on the periphery of the screw near the top and located at the top of the dam, and a gate hoist handwheel is installed on the top of the gate hoist base and located on the periphery of the screw.

[0009] As a preferred solution of the utility model, a cylindrical sealing cover is installed on the top of the oil storage tank, and the sealing cover intersects with the oil storage tank thread.

Therefore, when there is no need to open the gate, the sunshade and rain shield can be closer to the screw, the base of the gate hoist, the handwheel of the gate hoist and other components, so as to better protect them. When the gate needs to be opened, it can avoid affecting the operation of the staff.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, the sunshade and rain shield are arranged so that the sunshade and rain shield can effectively shade and protect the screw from the sun and rain, thereby preventing the lubricating oil on the surface from drying up and being washed away by rainwater and causing rust on the screw. The lubricating oil can be effectively stored in the oil storage tank, so that the lubricating oil can be slowly released on the surface of the screw through a dropper and slow-release cotton to lubricate the screw, thereby effectively preventing the lubricating oil from rusting. At the same time, no maintenance is required by the staff for a long time, which is very convenient. The electric push rod can adjust the height of the sunshade and rain shield, thereby preventing the staff from having difficulty in operation when the gate needs to be opened.

[0025] Example 1

[0026] like Figure 1-4 As shown, the utility model provides a technical solution: a water conservancy opening and closing gate, comprising a trapezoidal weir 1 and a gate plate 2 located on the inner side of the weir 1, strip-shaped slide grooves 3 are correspondingly opened on both sides of the gate plate 2 and on the inner side of the weir 1, and the gate plate 2 is slidably connected to the slide groove 3, a round roller-shaped screw 4 is vertically set on the top of the gate plate 2, and the screw 4 passes through the top of the weir 1 and extends upward, a cylindrical oil storage tank 5 is installed directly above the screw 4, and a cylindrical dropper 6 is connected to the bottom of the oil storage tank 5, and a triangular sunshade and rain shield 7 is installed above the oil storage tank 5, which can effectively block rain and sun, and the size of the sunshade and rain shield 7 can be customized as needed.

[0027] Example 2

[0028] like Figure 1-4 As shown, a connecting piece 41 is symmetrically installed on the periphery of the screw rod 4 near the bottom and on the top of the gate plate 2, and connecting rollers 42 that penetrate the connecting piece 41 are fixedly connected to both sides of the bottom of the connecting piece 41, so as to facilitate the connection between the screw rod 4 and the gate plate 2, thereby facilitating the opening of the gate.

[0029] A gate hoist base 43 is installed on the periphery of the screw rod 4 near the top and at the top of the dam 1, and a gate hoist handwheel 44 is installed on the top of the gate hoist base 43 and on the periphery of the screw rod 4, so that the screw rod 4 can be driven to rise and fall by the gate hoist handwheel 44 and the gate hoist base 43, thereby driving the gate plate 2 to rise and fall.

[0030] A cylindrical sealing cover 51 is installed on the top of the oil storage tank 5, and the sealing cover 51 intersects with the thread of the oil storage tank 5. A filter cotton 52 is installed inside the oil storage tank 5 near the top, and the interior of the dropper 6 is filled with slow-release cotton 61. The filter cotton 52 can effectively filter impurities in the lubricating oil.

[0031] A circular fixing frame 53 is fixedly connected to the periphery of the oil storage tank 5, a rectangular connecting block 54 is fixedly connected to the periphery of the fixing frame 53 near the back, a screw slider 8 is fixedly connected to the back of the connecting block 54, a rectangular mounting frame 81 is installed on the periphery of the screw slider 8, and the mounting frame 81 is fixedly connected to the sunshade and rain shield 7.

[0032] A linear guide 82 is provided on the front of the mounting frame 81 and located on the periphery of the screw slider 8, and the screw slider 8 is slidably connected to the linear guide 82. A screw 83 is rotatably connected inside the linear guide 82, and the screw 83 intersects with the screw slider 8 threadably. A drive motor 84 is fixedly connected to the bottom of the mounting frame 81, and the output end of the drive motor 84 passes through the linear guide 82 and is fixedly connected to the screw 83. The drive motor 84 can effectively drive the screw 83 to rotate, thereby driving the screw slider 8 to move up and down in the linear guide 82 through the screw 83, so as to adjust the distance between the oil storage tank 5 and the screw 4.

[0033] An electric push rod 71 is symmetrically fixed to the bottom of the sunshade and rain shield 7 . A support column 72 is sleeved on the periphery of the output end of the electric push rod 71 . The support column 72 is fixed to the top of the dam 1 .

[0034] The working process of the utility model is as follows: when using a hydraulic opening and closing gate, first, lubricating oil is injected into the oil storage tank 5, and the lubricating oil falls into the bottom of the oil storage tank 5 after being filtered by the filter cotton 52. When the lubricating oil is full, the sealing cover 51 is closed, and then the screw rod 83 is driven to rotate by the driving motor 84. The screw rod 83 drives the screw rod slider 8 to move in the linear guide rail 82, and the position between the dropper 6 and the screw rod 4 is adjusted by moving. After the adjustment is completed, the driving motor 84 is turned off. At this time, the lubricating oil passes through the slow-release cotton 61 in the penetration dropper 6, so that the lubricating oil slowly drips onto the screw rod 4. At this time, the screw rod 4 is lubricated by the lubricating oil and shielded by the sunshade and rain shield 7. The utility model can effectively avoid rust, so that when the gate needs to be opened, it can be ensured that the gate can be opened smoothly. When the gate needs to be opened, the sunshade and rain shield 7 are raised by the electric push rod 71. After raising, the sunshade and rain shield 7 will not affect the staff. The staff can stand on the dam 1 and turn the gate handwheel 44. Under the action of the gate handwheel 44 and the gate base 43, the screw 4 will rise upward, thereby driving the gate plate 2 to rise upward, so as to open the gate. The utility model can effectively protect the screw of the gate through design, thereby effectively avoiding rust and inconvenience in opening the gate, and maintenance is also very simple.
