Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic dams, in particular to a foldable hydraulic dam. Background Art

[0002] Patent authorization announcement number CN208121717U discloses a hydraulic dam structure comprising a door leaf, a bottom shaft disposed at the bottom of the door leaf, a hydraulic lifting rod disposed on the back of the door leaf, and a lifting support rod. The lifting support rod primarily comprises a primary support rod and a secondary support rod. The secondary support rod is a hollow sleeve structure, with the bottom of the primary support rod extending into the interior of the secondary support rod. A gravity lock is fixed to the upper portion of the secondary support rod. The gravity lock comprises a hydraulic cylinder and a telescopic lock member, and the hydraulic cylinder is provided with an oil inlet and an oil outlet. When the hydraulic dam structure is fully expanded, the telescopic lock member enters from one side of the secondary support rod and exits from the other side, passing through the primary support rod in the middle. The lifting support rod adopts a sleeve-type structure, which is stable and not easily damaged. The provision of the gravity lock can ensure and enhance its support performance for the dam body, extending the service life of the support rod. The spoiler of the spoiler device extends out of the door leaf, facilitating a good landscape effect in front of the tilted door leaf.

[0003] Among them, in the existing technology, when the hydraulic dam is in use, if the upstream water level rises too quickly, the door leaf dam plate will be subjected to greater pressure during the deflection and lifting process, requiring the working pressure of the hydraulic cylinder to increase, and it is easy for the working requirements to be not met; in addition, due to the working characteristics of the hydraulic cylinder, when two groups of hydraulic cylinders are used, it is easy for the extension and retraction speeds of the hydraulic cylinders in different positions to be different, resulting in uneven force on the back of the door leaf dam plate. Utility Model Content

[0004] The purpose of the utility model is to provide a folding hydraulic dam to solve the problems of the risk of the door leaf dam being subjected to greater pressure during the deflection and lifting process of the conventional folding hydraulic dam and the uneven force on the back of the door leaf dam.

[0008] Wherein, the support rod is adjusted for deflection by the folding hydraulic cylinder;

[0009] A pressure relief opening is provided in the middle of the gate dam board. A gate plate limit seat is arranged on the gate dam board and on the outer peripheral side of the pressure relief opening. A pressure relief gate that is adjusted for opening and closing by a gate adjusting cylinder is limit-arranged in the gate plate limit seat.

[0010] Furthermore, sealing splicing grooves are respectively arranged on both side edges of the gate dam board; adjacent gate dam boards are hermetically connected by a flat insertion method.

[0011] Still further, the limit slide rail includes two brackets fixed on the dam foundation, and horizontal sliding grooves are provided on the brackets;

[0012] Wherein, the sliding seat is a bearing limited in the middle of the limit slide rail, and the connecting rod penetrates through the sliding groove and is connected with the sliding seat.

[0013] Still further, the lower end of the folding hydraulic cylinder is hinged on the dam foundation through a second hinge seat, and the telescopic end of the folding hydraulic cylinder is hinged and connected with the support rod through a first hinge seat.

[0014] Still further, a plug-in groove with a "U" cross-section is formed between the gate plate limit seat and the gate dam board, and the pressure relief gate is hermetically inserted into the plug-in groove.

Detailed implementation mode

[0022] In this embodiment, a folding hydraulic dam is disclosed, which includes a dam foundation 100, a plurality of gate dam plates 200 hinged to the dam foundation 100, and a plurality of folding hydraulic cylinders 500 installed on the dam foundation 100 and used to adjust the deflection of the gate dam plates 200.

[0023] During specific use, a relatively wide range of folding dams are formed by the cooperation of the plurality of gate dam plates 200.

[0024] As Figure 1 shown, in this embodiment, two symmetric upper hinge seats 301 are fixedly installed on the back of the gate dam plate 200. Support rods 300 are respectively hinged to the two upper hinge seats 301. A sliding seat 302 is installed at the lower end of the support rod 300. A limit slide rail 400 adapted to the sliding seat 302 is fixedly installed on the dam foundation 100. The two sliding seats 302 are connected by a connecting rod 303. The support rod 300 is adjusted for deflection by the folding hydraulic cylinder 50%. Specifically, the lower end of the folding hydraulic cylinder 500 is hinged to the dam foundation 100 through a second hinge seat 502, and the telescopic end of the folding hydraulic cylinder 500 is hinged to the support rod 300 through a first hinge seat 501.

[0025] In this embodiment, the limit slide rail 400 includes two brackets fixed on the dam foundation 100, and a horizontal sliding groove 401 is formed on the brackets. The sliding seat 302 is a bearing limited in the middle of the limit slide rail 400, and the connecting rod 303 passes through the sliding groove 401 and is connected to the sliding seat 302.

[0026] During use, through the telescopic adjustment of the folding hydraulic cylinder 500, the support rod 300 is driven to deflect. At the same time, since the sliding seats 302 at the lower ends of the two support rods 300 are connected by a connecting rod 303, the two support rods 300 can be driven to synchronously drive the gate dam plate 200 to deflect and adjust.

[0027] As Figure 1 and Figure 3As shown in the figure, a pressure relief opening 202 is provided in the middle of the gate dam plate 200. A gate limiting seat 600 is fixedly installed on the gate dam plate 200 and on the outer peripheral side of the pressure relief opening 202. A pressure relief gate 700 that is adjusted to open and close by a gate adjusting cylinder 800 is installed in the gate limiting seat 600 in a limited manner. A plug-in groove with a "U" cross-section is formed between the gate limiting seat 600 and the gate dam plate 200. The pressure relief gate 700 is hermetically inserted into the plug-in groove. The gate adjusting cylinders 800 for adjusting the lifting of the pressure relief gate 700 are fixed on both sides of the gate limiting seat 600.

[0028] When adjusting the water level, if the upstream water level rises too fast, it will cause the gate dam plate 200 to bear a large pressure during the process of deflection and lifting, and the working pressure of the hydraulic cylinder needs to be increased.

[0029] To cope with this situation, in this embodiment, during use, first adjust the pressure relief gate 700 to rise through the gate adjusting cylinder 800, so as to open the pressure relief opening 202; then, use the folding hydraulic cylinder 500 to drive the gate dam plate 200 to deflect to meet the working setting requirements; finally, adjust the pressure relief gate 700 to descend through the gate adjusting cylinder 800 to close the pressure relief opening 202.

[0030] During specific implementation, the dam foundation 100 is designed as a stepped structure, and the lowermost end of the gate dam plate 200 is lower than the bottom surface of the water channel; in this embodiment, to ensure the sealing performance between adjacent gate dam plates 200.

[0031] Such as Figure 2 As shown in the figure, sealing splicing grooves 201 are prefabricated on both sides of the gate dam plate 200; adjacent gate dam plates 200 are hermetically connected by a flat insertion method to adjust the sealing performance of the side.

[0032] The above embodiments only describe the preferred ways of the present invention, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should all fall within the protection scope determined by the claims of the present utility model.
