Description

A water retaining device

Technical Field

The utility model relates to the technical field of water conservancy projects, in particular to a water retaining device.

Background Art

Water conservancy engineering mainly studies the basic knowledge and skills in engineering hydrology, water conservancy engineering surveying, water conservancy reinforced concrete, hydraulic structures, engineering drawing, etc., and conducts engineering planning and design, engineering site construction, engineering budgeting, and water conservancy equipment maintenance and repair in the field of water conservancy engineering. For example: building different types of hydraulic structures such as dams, dikes, spillways, sluices, channels, ferry canals, rafts, and fishways. Among them, sluices are low-head hydraulic structures built on rivers and channels that use gates to control flow and adjust water levels. Closing the gates can block floods, block tides, or raise upstream water levels to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industrial and domestic water use; opening the gates can discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices are widely used as structures for retaining, discharging or taking water.

For example, a river sluice disclosed in the publication number CN209760175U includes piers arranged on both sides of the river, a liftable gate is arranged on the piers, a base is arranged between the piers, a net bag is arranged between the gate and the base, the net bag is arranged on the side of the gate outlet, the net bag is detachably connected to the gate and the base, and the length of the net bag is greater than the height of the gate rises. Through the above arrangement, the net bag is arranged on the side of the gate outlet, so that when the gate is opened, the net bag intercepts the garbage and aquatic plants carried in the water flow, and stores the garbage and aquatic plants in the net bag, thereby reducing the pollution to the river. The net bag is detachably connected to the gate and the base, so that the net bag is opened when the gate is raised to filter the water flow. After the gate falls to intercept the water flow, the net bag can be manually disassembled and cleaned, and the garbage and aquatic plants in the net bag can be cleaned, so that the net bag can be prepared to clean the water flow when the gate is opened to release water next time.

However, the water retaining device in the above technology still has the following problems:

Although garbage, aquatic plants, etc. in the river can be intercepted by net bags, when the sluice gate is opened to release water, the water flow will rapidly impact from the bottom of the sluice gate as the sluice gate is pulled up, causing a large scouring force on the dam body at the bottom of the sluice gate. Not only will it cause a certain impact on the net bag, causing damage to the net, but in the long run, it will also cause the dam body at the bottom of the sluice gate to be eroded by the rapid impact of the water flow, causing potholes and damage to the dam body.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Please refer to Figures 1 to 5. A water retaining device includes a support frame 11 installed on a gate pier 1. The inner walls on both sides of the support frame 11 are provided with slide grooves 101. A gate group is slidably connected between the two slide grooves 101. The gate group includes a bottom gate plate 2, a top gate plate 3 and a plurality of branch gate plates 4. Both ends of the bottom gate plate 2, the top gate plate 3 and the plurality of branch gate plates 4 are respectively slidably connected to the two slide grooves 101. The plurality of branch gate plates 4 are located between the bottom gate plate 2 and the top gate plate 3 and abut against each other. A progressive component 5 is connected between the bottom gate plate 2, the top gate plate 3 and the plurality of branch gate plates 4. A lifting component 6 is connected between the top gate plate 3 and the top of the support frame 11.

As shown in Figures 1 to 5, a water retaining device in the utility model is similar to the structure of an existing water retaining device, such as a river sluice disclosed in the patent with publication number CN209760175U. The main improvement of the utility model is that the user can drain water layer by layer from top to bottom according to the water depth, reduce the impact force of the water flow on the bottom of the dam body, and reduce the damage to the dam body. As shown in Figures 1 to 5, when the water retaining device in the utility model is in use, when it is necessary to discharge the upstream river water into the downstream, the top gate plate 3 is driven upward by the lifting component 6, and then the top gate plate 3 drives the progressive component 5 to lift up multiple branch gate plates 4 and the bottom bottom gate plate 2 in turn, thereby forming gaps arranged in sequence between the top gate plate 3, multiple branch gate plates 4 and the bottom gate plate 2, and performing drainage operations from high to low, thereby avoiding direct drainage from the bottom of the gate to form a rapid water flow to impact the dam body, causing damage to the dam body, and improving the safety of the dam body.

As shown in Figure 3, the progressive component 5 includes a connecting rod 51 and several symmetrically arranged connecting blocks 52. The middle sections of the bottom gate plate 2, the top gate plate 3 and the several branch gate plates 4 are all provided with progressive cavities 501. One end of the connecting rod 51 away from the support frame 11 is against the bottom surface of the progressive cavity 501 in the bottom gate plate 2, and the other end simultaneously penetrates the several branch gate plates 4 and the bottom surface of the top gate plate 3 to communicate with the progressive cavity 501 in the top gate plate 3. The connecting rod 51 is slidably connected to the bottom gate plate 2, the top gate plate 3 and the several branch gate plates 4. The several symmetrically arranged connecting blocks 52 are respectively slidably connected to the inner walls of the several progressive cavities 501, and are fixedly connected to the outer wall of the connecting rod 51. When the top gate plate 3 moves upward, when the bottom surface abuts against the connecting block 52, it can drive the connecting rod 51 to move upward, and then drive the sub-gate plates 4 of the same group to move upward through the connecting block 52 below, and so on, and finally all the sub-gate plates 4 and the bottom gate plates 2 are lifted up in sequence to form gaps between them, so that the water flow can be discharged layer by layer through the gaps, avoiding the water flow directly flowing into the downstream from the bottom to generate rapid water flow to impact the dam body.

As shown in Figure 3, the connecting block 52 in the bottom gate plate 2 abuts against the bottom inner wall of the same group of progressive cavities 501, and the distance between the bottom gate plate 2 and the connecting blocks 52 in several branch gate plates 4 gradually increases toward the top gate plate 3, and the connecting block 52 in the top gate plate 3 abuts against the top inner wall of the same group of progressive cavities 501. When the bottom gate plate 2, the branch gate plate 4 and the top gate plate 3 are lowered for water retaining operations, the top gate plate 3 is squeezed to drive the same group of connecting blocks 52 to be squeezed downward, and the bottom bottom gate plate 2 is subjected to downward pressure through the connecting rod 51 and the bottom connecting block 52, thereby improving the connection firmness between the bottom gate plate 2 and the riverbed or the dam body, wherein the distances between the multiple groups of symmetrical connecting blocks 52 are in an increasing relationship from bottom to top, such as the distance between a group of connecting blocks 52 in the bottom gate plate 2 and a group of connecting blocks 52 in the adjacent branch gate plate 4 is A, and the distances between the two adjacent groups of connecting blocks 52 above are A+1, A+2, A+3, etc., so that when the gate is lifted, the top gate plate 3, the branch gate plate 4 and the bottom gate plate 2 can be lifted upward in turn, so that gaps are formed between the gate plates so that water can flow out in layers.

As shown in Fig. 1 to Fig. 4, the lifting assembly 6 includes an external threaded rod 61 and a turntable 62. A threaded hole 102 is formed through the middle section of the top of the support frame 11. One end of the external threaded rod 61 is fixedly connected to the turntable 62, and the other end passes through the threaded hole 102 and is connected to the top gate plate 3 with a rotating assembly 7. The external threaded rod 61 is threadedly connected to the threaded hole 102. When the lifting assembly 6 is used to lift the top gate plate 3 upward, the external threaded rod 61 is rotated by rotating the turntable 62, and rotates with the threaded hole 102 on the support frame 11, so that the external threaded rod 61 moves upward or downward, and the top gate plate 3 is lifted up and down by the rotating assembly 7.

As shown in Fig. 2 to Fig. 5, the rotating assembly 7 includes a plane bearing 71 and a connecting sleeve 72. One end of the connecting sleeve 72 is fixedly connected to the side of the top gate plate 3 close to the external threaded rod 61. The inner wall of the connecting sleeve 72 away from the top gate plate 3 is fixedly connected to the edge of the side of the plane bearing 71 away from the top gate plate 3. The end of the external threaded rod 61 away from the turntable 62 passes through the plane bearing 71 and is fixedly connected to the inner wall of the side of the plane bearing 71 close to the top gate plate 3. When the external threaded rod 61 rotates and lifts, it drives the bottom surface of the plane bearing 71 to rotate, while the upper side plate of the plane bearing 71 moves up and down with the connecting sleeve 72 without rotating, and drives the top gate plate 3 to move upward through the connecting sleeve 72. The use of the plane bearing 71 can greatly reduce the friction between the rotating external threaded rod 61 and the top gate plate 3, which is more conducive to the rotating external threaded rod 61 for lifting operations.

As shown in Fig. 2 to Fig. 4, the bottom gate plate 2 and the plurality of gate plates 4 are provided with convex strips 21 on one side close to the top gate plate 3, and the top gate plate 3 and the plurality of gate plates 4 are provided with grooves 201 matching the convex strips 21 on one side close to the bottom gate plate 2, and the adjacent convex strips 21 and grooves 201 are mutually engaged. By mutually engaging the convex strips 21 and grooves 201 between the bottom gate plate 2, the plurality of gate plates 4 and the top gate plate 3, the overall connection firmness of the gate can be improved, the water retaining capacity can be improved, and the connection sealing between the gate plates can be increased, water can be prevented from flowing out of the connection gaps of the gate plates, and the tightness of the connection can be improved.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
