DETAILED DESCRIPTION

[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 some existing water retaining dams have triangular support mechanisms on their back side, but in some cases, such as when the water flow impact is large, the geological conditions are complex or the dam body is high, the load-bearing capacity is limited, deformation or damage is easy to occur, the stability is not ideal, and there is a lack of self-locking structure. Even if self-locking blocks and other components are set, they still need to be manually installed and fixed, which is very inconvenient to operate. Please refer to Figure 1-Figure 2The utility model provides a self-locking water retaining dam with a triangular support mechanism, comprising a base 1 and a dam body 2 located at the end of the base 1 and hinged therewith, a first hydraulic cylinder 3 for adjusting the angle of the dam body 2 is provided between the backwater side of the dam body 2 and the base 1, a plurality of equally spaced tripods 4 are also fixedly provided on the backwater side of the dam body 2, a plurality of arc-shaped support frames 5 corresponding to the tripods 4 one by one and slidingly cooperating with the tripods 4 are provided on the side of the base 1 away from the dam body 2; a self-locking component 6 for limiting the rotation of the tripod 4 is provided on the side of the arc-shaped support frame 5. When the angle of the dam body 2 needs to be adjusted, the self-locking component 6 and the tripod 4 are in a separated state, and the dam body 2 is driven by the first hydraulic cylinder 3 to adjust the angle, and after reaching the desired angle, the self-locking component 6 controlled by the hydraulic pressure moves to the tripod 4 again to contact it, and locks the tripod 4 on the arc-shaped support frame 5 to prevent it from rotating.

[0028] like Figure 3 As shown, a first slider 401 is fixedly provided on the corner of the tripod 4 away from the dam body 2, and a limiting rod 402 is fixedly passed through the first slider 401; a through slot for slidingly cooperating with the first slider 401 is provided on the arc support frame 5, and a slot for the limiting rod 402 to pass through is provided on the side of the arc support frame 5. When the dam body 2 is driven to rotate by the first hydraulic cylinder 3, the dam body 2 drives the tripod 4 to rotate, at which time the first slider 401 slides along the through slot, and the limiting rod 402 slides along the slot. After the dam body 2 rotates to the desired position, the tripod 4 is locked on the arc support frame 5 by the self-locking component 6.

[0029] In order to improve the overall stability and load-bearing capacity of the tripod 4, it is convenient to control the locking of the tripod 4 on the shore, such as Figure 4-Figure 5As shown, the self-locking component 6 includes a plurality of arc plates 601 respectively located on the sides of the corresponding arc support frames 5; an arc trough is provided on the side of the arc plate 601 close to the arc support frame 5, and a plurality of evenly distributed columns 602 are provided in the arc trough, and a spring 603 is fixed in the cavity at the inner end of the column 602, and the diameter specification of the limit rod 402 is the same as that of the column 602; it also includes a mounting plate 604 sliding on the foundation below the arc support frame 5 and a second hydraulic cylinder 605 for driving the mounting plate 604 to move, and the plurality of arc plates 601 are fixed on the top of the mounting plate 604. When in use, the second hydraulic cylinder 605 drives the mounting plate 604 to move, the mounting plate 604 drives multiple arc plates 601 to move, and the arc plates 601 drive the columns 602 therein to move. When the limiting rod 402 contacts the column 602 at the corresponding position, as the column 602 continues to move, the limiting rod 402 applies pressure to the column 602. At this time, the spring 603 is compressed until the limiting rod 402 extending from the side of the arc-shaped support frame 5 is fully inserted into the arc-shaped groove body. The limiting rod 402 is supported and limited by multiple columns 602, thereby preventing the tripod 4 from rotating. The staff controls the tripod 4 on the shore to achieve self-locking.

[0030] In order to reduce the impact force of water flow on the dam body 2, the bottom end of the arc-shaped support frame 5 extends to the bottom of the base 1 and is fixed on the foundation; the top end of the arc-shaped support frame 5 extends to the top of the water-facing side of the dam body 2, and is integrally formed with a vertical plate body 501 for dispersing water flow. Multiple vertical plates 501 can disperse the water flow, reduce the impact force of the water flow on the dam body 2, protect the dam body 2 from the direct impact of strong water flow, improve its flood prevention capacity and stability, and can also effectively adjust the water flow speed, so that the water flow forms a certain turbulence and eddy current when passing through the gap of the vertical plates 501, which helps to consume the kinetic energy of the water flow.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, in order to solve the problem that the existing water barrier dam is difficult to effectively intercept and salvage the dirt, the large amount of dirt accumulated on the dam plate affects the smooth flow of water, and the cleaning work is difficult and costly, such as Figure 1 , Figure 6 As shown, a cleaning assembly 7 for salvaging dirt in the water body is provided on the water-facing side of the dam body 2 , and the upper portion of the cleaning assembly 7 is fixed on the arc-shaped support frame 5 .

[0033] The cleaning assembly 7 includes a salvage trough 701 and a support 702 fixed on the side of the salvage trough 701; a second slider 703 hinged to the end of the support 702 is provided, and a slide groove slidably matched with the second slider 703 is provided on the water-facing side of the dam body 2; it also includes a reel seat 704 fixed on the top of the arc-shaped support frame 5 and a guide wheel seat 705 fixed on the bottom of the arc-shaped support frame 5; the wire rope wound on the reel seat 704 passes around the guide wheel seat 705 and is fixedly connected to the middle part of the salvage trough 701. When in use, the motor on the drum seat 704 is started, and the motor drives the drum seat 704 to rotate, the wire rope is reeled in, and the salvage trough 701 is pulled along the slide groove to move to the upper end of the water-facing side of the dam body 2 to facilitate the staff to remove the dirt; the hinged setting of the support 702 and the second slider 703 enables the salvage trough 701 to adapt to the use of the dam body 2 at different angles, and can always maintain a horizontal state, which is conducive to the salvage of dirt, and during the lifting process of the salvage trough 701, it can tilt upward to prevent the dirt in the salvage trough 701 from falling.

[0034] 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.
