[0002] The hydraulic lifting dam uses the hydraulic cylinder to directly push the back of the movable water retaining dam surface with the bottom as the axis, so as to achieve the purpose of raising the dam to retain water and lowering the dam to discharge floods. It is widely used in agricultural irrigation, fisheries, ship locks, seawater tidal barriers, urban river landscape projects and small hydropower stations.

[0003] Compared with traditional sluice gates and rubber dams, hydraulic lifting dams have significant advantages, such as simple structure, easy construction, flexible operation, high degree of automation, strong flood discharge capacity, etc. However, it also has some shortcomings, such as the need to use water-stop components to seal between the dam bodies of the hydraulic lifting dam to prevent water seepage, but the existing sealing water-stop components are relatively simple, the sealing water-stop effect is not ideal, and the sealing water-stop components are difficult to open and close automatically to adapt to the lifting and lowering of the dam body. When the dam body needs to be lifted or lowered, the state of the sealing water-stop components needs to be manually adjusted, and the manual adjustment efficiency is low, and there is a certain degree of danger.

[0004] To this end, we provide a hydraulic lifting dam that can be opened and closed automatically to solve the above-mentioned problems. Summary of the invention

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Embodiment 1

[0027] In order to solve the problem that the sealing and water-stopping performance between the dam bodies of the existing hydraulic lifting dams is poor and it is difficult to open and close automatically to adapt to the lifting of the dam body, please refer to Figure 1-Figure 3The utility model provides a hydraulic lifting dam that can be opened and closed automatically, including a base 1 and a dam body 2 hinged at the end of the base 1. A first hydraulic cylinder 3 for adjusting the angle of the dam body 2 is provided between the back surface of the dam body 2 and the base 1. The two narrow sides of the dam body 2 are provided with mounting grooves 201. The mounting grooves 201 are respectively provided with first water-stopping rubber blocks 4 and opening and closing components 5 for pushing the first water-stopping rubber blocks 4. The gaps between adjacent dam bodies 2 are water-stopped by the two first water-stopping rubber blocks 4 being pressed against each other. When the dam body 2 descends, the adjacent first water-stopping rubber blocks 4 are disconnected. When the dam body 2 rises and resets, the two first water-stopping rubber blocks 4 are automatically closed through the opening and closing components 5, and the gaps between the dam bodies 2 are sealed and water-stopped.

[0028] The first water-stopping rubber block 4 is provided with a first wedge surface 401 at the water-facing surface and the water-receiving surface and at the corner away from the dam body 2, and the adjacent first water-stopping rubber blocks 4 are contracted inwardly by the cooperation of the first wedge surfaces 401. The setting of the first wedge surface 401 enables the first water-stopping rubber block 4 to smoothly extend and retract, thereby facilitating the automatic opening and closing of the opening and closing assembly 5 to adapt to the lifting and lowering of the dam body 2.

[0029] like Figure 4 As shown, the opening and closing assembly 5 includes a fixing seat 501 fixed in the mounting groove 201 and a first movable rod 502 movably penetrating the fixing seat 501; a first mounting plate 503 for mounting the first waterproof rubber block 4 is fixed to the outer end of the first movable rod 502, and a first spring 504 is sleeved on the first movable rod 502 between the first mounting plate 503 and the fixing seat 501. When the first waterproof rubber block 4 is subjected to force, the first mounting plate 503 is driven to move inward, and the first mounting plate 503 drives the first movable rod 502 to move inward, at which time the first spring 504 is compressed, and under the action of the first spring 504, the two first waterproof rubber blocks 4 are tightly fitted together.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to further improve the sealing and water stopping effect at the gap between adjacent dam bodies 2, as shown in FIG. Figure 1-Figure 3 As shown, the backwater side of the gap between adjacent dam bodies 2 is also provided with a second water-stop rubber block 6 for pressing the first water-stop rubber block 4 and a pressing assembly 7 for pushing the second water-stop rubber block 6. The second water-stop rubber block 6 can ensure a tighter fit between the two first water-stop rubber blocks 4, reduce the gap, and effectively prevent water penetration.

[0032] The second water-stop rubber block 6 is provided with a groove for inserting the two first water-stop rubber blocks 4, and a third wedge surface 601 is provided in the groove. The back surface of the first water-stop rubber block 4 and the corner close to the dam body 2 are provided with a second wedge surface 402 that matches the third wedge surface 601. When the clamping assembly 7 pushes the second water-stop rubber block 6, the cooperation between the third wedge surface 601 and the second wedge surface 402 drives the two first water-stop rubber blocks 4 to move closer to each other, so that they fit more closely.

[0033] like Figure 5 As shown, the clamping assembly 7 includes a U-shaped seat 701 and a second mounting plate 702 slidably disposed in the U-shaped seat 701 and used to mount the second waterproof rubber block 6; a second hydraulic cylinder 703 for driving the second mounting plate 702 to move is fixedly disposed on the outer surface of the U-shaped seat 701. The second mounting plate 702 is driven to move in the U-shaped seat 701 by the second hydraulic cylinder 703, and the second mounting plate 702 drives the second waterproof rubber block 6 to move until the second waterproof rubber block 6 is pressed against the back surface of the dam body 2. The second waterproof rubber block 6 can not only gather the two first waterproof rubber blocks 4 together to reduce the gap, but also play a further waterproof effect to prevent moisture from seeping out from the gap between the second waterproof rubber block 6 and the dam body 2.

[0034] Embodiment 3

[0035] On the basis of the first and second embodiments, in order to support the pressing assembly 7 and automatically adapt to the lifting and lowering of the dam body 2, as shown in FIG. Figure 1-Figure 2 , Figure 5 As shown, the back surface of the dam body 2 on both sides of the clamping assembly 7 is fixed with a fixing assembly 8 for supporting the clamping assembly 7, and the fixing assembly 8 is engaged with the clamping assembly 7. When the dam body 2 descends, the clamping assembly 7 can automatically disconnect from the fixing assembly 8 on the adjacent dam body 2, and when the dam body 2 rises, the clamping assembly 7 can automatically connect with the fixing assembly 8 on the adjacent dam body 2, and can automatically adapt to the lifting and lowering of the dam body 2, which is more convenient to use. The two fixing assemblies 8 jointly support the clamping assembly 7.

[0036] The fixing assembly 8 includes a fixing plate 801 fixed on the back surface of the dam body 2 and a plurality of equally spaced second movable rods 802 that are movable and penetrate the fixing plate 801; a conical clamping column 803 is fixedly provided at the outer end of the second movable rod 802, a plurality of equally spaced clamping holes 704 that are clamped and matched with the clamping column 803 are provided on the side of the U-shaped seat 701, a second spring 804 is sleeved on the second movable rod 802 between the clamping column 803 and the fixing plate 801; a fourth wedge surface 705 for the clamping column 803 to contract is provided at the corner of the U-shaped seat 701. When the dam body 2 descends, the fixing assembly 8 on it is driven to rotate, and the fixing assembly 8 drives the clamping assembly 7 to rotate, at which time the clamping assembly 7 and the fixing assembly 8 on the adjacent dam body 2 are twisted, and the clamping column 803 of the fixing assembly 8 on the adjacent dam body 2 leaves the clamping hole 704, thereby disconnecting from the clamping assembly 7.

[0037] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
