Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment

[0029] Refer to Figures 1-6As shown in the figure, a water conservancy construction water retaining device includes a cut-off plate 1. Two groups of extension plates 211 are slidably connected to the inner wall of the cut-off plate 1. A vertical rack 218 is inserted into the inner wall of the top end of the cut-off plate 1. A movable plate 217 is fixed to the bottom end of the vertical rack 218. Fixed columns 214 are fixed to the opposite side surfaces of the two groups of extension plates 211. A fixed block 215 is fixed to the end of the fixed column 214 away from the first gasket 212. A rotating roller 216 is rotatably connected to the inner wall of the fixed block 215. By vertically pulling the vertical rack 218, the movable plate 217 is driven to move inside the cut-off plate 1. When the movable plate 217 is pressed down, it will squeeze the rotating roller 216 and push the fixed block 215, the fixed column 214 and the extension plate 211 to extend outward from the cut-off plate 1, so as to achieve the purpose of adjusting the water retaining range of the cut-off plate 1. Second gaskets 213 are fixed to the opposite side surfaces of the two groups of first gaskets 212, and first gaskets 212 are fixed to the front and rear outer walls of the two groups of first gaskets 212. The first gaskets 212 and the second gaskets 213 are both made of rubber material and have good sealing effects, which can prevent water flow from passing through the gap between the extension plate 211 and the cut-off plate 1 and improve the comprehensiveness of water retaining. The shape of the movable plate 217 is an inverted trapezoid. The outer wall of the movable plate 217 is in contact with the rotating roller 216. By setting the movable plate 217, a better guiding effect can be achieved, which is convenient for stably pushing the two groups of rotating rollers 216 to extend outward at equal intervals and ensures that the adjustment of the interval is more convenient. Guide holes 225 are formed on the opposite side surfaces of the two groups of extension plates 211. A fixed plate 223 is fixed to the inner wall of the cut-off plate 1. A guide rod 224 corresponding to the guide hole 225 is fixed to the outer wall of the fixed plate 223. A first spring 226 is wound around the outer wall of the guide rod 224. One end of the first spring 226 is connected to the fixed plate 223 and the other end is connected to the outer wall of the extension plate 211. When the extension plate 211 moves under the action of the guide rod 224 and the guide hole 225, the first spring 226 will be driven to stretch. After the movable plate 217 moves upward, under the elasticity of the first spring 226, the two groups of extension plates 211 can rebound and reset, and drive the two groups of extension plates 211 to be received inside the cut-off plate 1.

[0030] A support frame 220 is fixed to the top end of the cut-off plate 1. A motor 221 is installed on the outer wall of the support frame 220. The output end of the motor 221 is connected to a rotating rod 222. A rotating gear 219 meshing with the vertical rack 218 is fixed to the end of the rotating rod 222 away from the motor 221. By starting the motor 221, the rotating rod 222 and the rotating gear 219 can be driven to rotate. The rotating gear 219 meshes with the vertical rack 218 and pushes the vertical rack 218 and the movable plate 217 to move vertically back and forth, achieving an automatic control effect and improving the working efficiency of the equipment.

[0031] There are two groups of connecting plates 312 fixed to the rear end of the intercepting plate 1. A support plate 311 is rotatably connected to the opposite side surfaces of the two groups of connecting plates 312. The support plate 311 can support the ground, and the intercepting plate 1 can rotate on the support plate 311, so as to perform water blocking operations for canals with different inclination angles.

[0032] A fixing frame 313 is fixed to the outer wall of the support plate 311. A number of groups of pin holes 315 are formed inside the connecting plate 312. A pin rod 314 corresponding to the pin holes 315 penetrates through the fixing frame 313. After the intercepting plate 1 is adjusted, the pin rod 314 is inserted into the pin holes 315, so that the connection between the intercepting plate 1 and the support plate 311 is more stable. A handle 316 is fixed to the outer wall of the pin rod 314. The handle 316 is connected to the fixing frame 313 through a second spring 317. The setting of the second spring 317 can achieve better stability, ensure that the pin rod 314 is inserted into the pin holes 315 more stably, and is relatively easy to use.

[0033] Working principle: When it is necessary to adjust the water blocking range, the motor 221 is started to drive the first gasket 212 and the rotating gear 219 to rotate. After the rotating gear 219 meshes with the vertical rack 218, it drives the vertical rack 218 and the movable plate 217 to move downward. At this time, the movable plate 217 abuts against the rotating roller 216 and causes the rotating roller 216 to rotate. After the rotating roller 216 is squeezed along the inclined direction of the movable plate 217, it will push the fixed column 214 and the extension plate 211 to move outward from the intercepting plate 1. At this time, the first gasket 212 slides on the outer wall of the guide rod 224, causing the first spring 226 to be stretched. In this way, the water blocking area can be increased, which is convenient for performing water blocking operations for wider canals. When the motor 221 is started to raise the movable plate 217, the two extension plates 211 can contract toward the inside of the intercepting plate 1 under the elasticity of the first spring 226, achieving the purpose of storage, which is convenient for the staff to transport and carry the intercepting plate 1.

[0034] When it is necessary to support the intercepting plate 1, the handle 316 is pulled to pull the pin rod 314 outward. At this time, the second spring 317 will be stretched. Subsequently, the support plate 311 is rotated to support the ground. By adjusting the intercepting plate 1, the intercepting plate 1 can be turned, which is convenient for fitting with the inner wall of the canal. After the adjustment is completed, by releasing the handle 316, the pin rod 314 can be driven to insert into the pin holes 315 under the elasticity of the second spring 317, achieving the purpose of locking the support plate 311 and the intercepting plate 1.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
