Description

Technical Field

[0001] The utility model relates to the technical field of farmland water conservancy, and specifically relates to an integral check gate for farmland water conservancy. Background Technique

[0002] Farmland water conservancy refers to the water conservancy engineering measures for the purpose of increasing agricultural production and serving agricultural production. By building and applying various water conservancy engineering facilities, the natural conditions unfavorable to the development of agricultural production are changed, the virtuous cycle of the ecological environment is promoted, and services are provided for high-yield and high-efficiency agriculture. At present, in farmland water conservancy, an integral check gate for farmland water conservancy is often used to irrigate, drain, and remove waterlogging from farmland.

[0003] The existing integral check gate usually controls the up and down movement of a gate plate to regulate the water flow. However, in the actual use process, since the water flow often contains foreign matters such as gravel, if these foreign matters fall below the gate plate, when the gate plate needs to be completely sealed and closed, the gate plate drops, and there will be a gap between its bottom and the water channel, resulting in incomplete sealing and water leakage. Therefore, a new type of integral check gate for farmland water conservancy is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integral check gate for farmland water conservancy to solve the problems raised in the above background technique.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 - 5 shown, the present utility model provides a technical solution: an overall check gate for farmland water conservancy, including:

[0026] A fixed seat 1, with a pier 104 provided at the top of the fixed seat 1, a protection box 105 provided at the top of the pier 104, a gate panel 103 slidably provided inside the pier 104, second diversion slopes 102 provided on the front and rear sides at the top of the fixed seat 1, a first diversion slope 101 provided at the bottom inside the pier 104, and a control mechanism 2 provided inside the pier 104 for controlling the lifting of the gate panel 103 inside the pier 104;

[0027] An ejection mechanism 3, provided at the bottom inside the pier 104 for ejecting the gravel and sediment that fall inside the bottom of the pier 104 out of the pier 104.

[0028] The control mechanism 2 includes:

[0029] The cavities 206 are arranged on the left and right sides of the pier 104. A threaded rod 204 is arranged in the cavity 206. A sliding groove 205 is arranged on the cavity 206. The height of the sliding groove 205 is slightly higher than the height of the gate plate 103. The sliding groove 205 is arranged in the upper part of the cavity 206. Convex grooves 208 are arranged on the left and right sides of the pier 104. The convex grooves 208 extend to the inner bottom end of the pier 104 and do not penetrate through.

[0030] On the left side of the top end of the protection box 105, a motor 201 is arranged. The output end of the motor 201 is connected to the threaded rod 204. A threaded seat 203 is arranged on the outer wall of the threaded rod 204. On one side of the threaded seat 203, a fixed block 207 is arranged. The fixed block 207 is located in the sliding groove 205. A gate plate 103 is arranged between the fixed blocks 207.

[0031] The left and right sides of the gate plate 103 are located in the convex grooves 208. The top end of the threaded rod 204 penetrates through the outer wall of the protection box 105. A sprocket 209 is arranged on the outer wall of the threaded rod 204. The sprockets 209 are connected by a chain 202. The sprockets 209 are located in the protection box 105.

[0032] As Figure 4 shown, it should be noted that when the gate plate 103 is used to control the farmland water conservancy, the motor 201 drives the threaded rod 204 to rotate. During the rotation of the threaded rod 204, the sprocket 209 is driven to rotate. The sprockets 209 are connected by a chain 202. The chain 202 drives the threaded rod 204 inside the sprocket 209 to rotate synchronously. During the synchronous rotation of the threaded rod 204, the threaded seat 203 is driven to lift in the cavity 206. The outer wall of the threaded seat 203 is in contact with the inner wall of the cavity 206. During the lifting of the threaded seat 203, the gate plate 103 is driven to slide and lift in the convex groove 208 through the fixed block 207. The fixed block 207 is connected to the left and right sides of the top end of the gate plate 103. The fixed block 207 moves in the sliding groove 205. When the fixed block 207 moves to the bottom end of the sliding groove 205, the bottom end of the gate plate 103 presses the ejection mechanism 3 and sinks into the inner side of the bottom end of the pier 104. When the fixed block 207 moves to the top end of the sliding groove 205, the bottom end of the gate plate 103 is separated from the water surface. The part of the outer side of the threaded rod 204 not involved in the sliding groove 205 is higher than the maximum water level height, preventing water from entering the cavity 206 through the sliding groove 205 and improving the service life of the threaded rod 204.

[0033] The ejection mechanism 3 includes:

[0034] A plurality of square plates 301 are arranged at the inner bottom end of the pier 104. A push rod 306 is arranged at the top end of the square plate 301. The output end of the push rod 306 is connected with a pushing block 302. A sealing plate 310 is arranged at the top end of the pushing block 302. The sealing plate 310 is hermetically connected with the inner wall of the bottom end of the pier 104. A first spring 307 is arranged on the outer wall of the push rod 306. The first spring 307 is located between the pushing block 302 and the square plate 301.

[0035] A second jacket 311 is arranged on one side of the square plate 301. A fixing rod 303 is arranged between the pushing blocks 302. A plurality of first jackets 304 are arranged on the outer wall of the fixing rod 303. The first jackets 304 and the inner side of the second jacket 311 are connected with a connecting rod 309 through a short rod 305. A second spring 308 is arranged on the outer wall of the fixing rod 303. The second spring 308 is located between the first jackets 304.

[0036] As Figure 3 shown, it should be noted that: during the descending process of the gate plate 103, the sealing plate 310 is synchronously driven to descend. During the descending process of the sealing plate 310, the pushing block 302 is driven to descend. During the descending process of the pushing block 302, the push rod 306 is driven to expand and contract. During the expansion and contraction process of the push rod 306, the first spring 307 is driven to be compressed. During the compression process of the first spring 307, the connecting rod 309 is driven to move. During the moving process of the connecting rod 309, the first jacket 304 is driven to compress the second spring 308. The sealing plate 310 is tightly connected with the inner wall of the bottom end of the pier 104 to prevent water leakage. When the gate plate 103 rises, the second spring 308 and the first spring 307 rebound synchronously, driving the sealing plate 310 to rise rapidly, ejecting the gravel and sediment, and sliding out of the device through the first diversion slope 101 and the second diversion slope 102.

[0037] In summary, through the cooperation setting between the ejection mechanism 3 and the control mechanism 2, the overall check gate for farmland water conservancy can control the lifting of the gate plate 103 in the pier 104 and prevent gravel and sediment from entering the inner side of the pier 104.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
