Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a flood prevention device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. In water conservancy projects, flood control devices are often used to control the flow of water to avoid floods. Common flood control devices include embankments, reservoirs, and sluices. Sluices can be divided into lifting sluices and rotating sluices according to their structure.

[0003] When some existing lifting sluice gates are used, in order to ensure the sealing between the water retaining plate and the frame, a U-shaped sealing strip is set on the outside of the water retaining plate or the inside of the frame. In the daily operation of the lifting sluice gate, the sealing between the water retaining plate and the frame is crucial, and the U-shaped sealing strip is the key component to achieve this sealing. However, as the water retaining plate is raised and lowered, the U-shaped sealing strip will produce continuous contact friction with the frame or the water retaining plate, which not only accelerates the wear of the sealing strip, causing the sealing effect to gradually weaken, but also increases the resistance and energy consumption during the lifting process. For this reason, a flood control device for water conservancy projects is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a flood control device for water conservancy projects, which can solve the problem that the sealing between the water baffle and the frame is crucial in the daily operation of the lifting sluice, and the U-shaped sealing strip is the key component to achieve this sealing. However, as the water baffle is raised and lowered, the U-shaped sealing strip will produce continuous contact friction with the frame or the water baffle, which not only accelerates the wear of the sealing strip, causing the sealing effect to gradually weaken, but also increases the resistance and energy consumption during the lifting process.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a flood control device for water conservancy projects, comprising a frame and:

[0006] A water blocking mechanism, which is arranged on the outer surface of the frame and is used to block water flow;

[0008] The transmission mechanism is arranged on the inner side of the frame, the transmission mechanism is fixedly connected to the water blocking mechanism, and the transmission mechanism is in contact with the sealing mechanism and is used to drive the sealing mechanism.

[0009] Preferably, the water-blocking mechanism comprises a multi-stage hydraulic cylinder arranged on the outer surface of the frame, and an output end of the multi-stage hydraulic cylinder is provided with a water baffle, and the water baffle is slidably connected to the frame.

[0010] Preferably, the sealing mechanism includes a sealing strip arranged at the bottom inner side of the frame, the sealing strip is in contact with the water baffle, two sealing plates are slidingly arranged on the inner surface of the frame, both of the sealing plates are in contact with the water baffle, and a spring is provided on the outer surface of the sealing plate, which is fixedly connected to the frame.

[0014] Preferably, two buffer blocks are provided on the outer surface of the sealing plate away from the spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present application can meet the sealing requirements of the water baffle through the arrangement of the water-blocking mechanism, the sealing mechanism and the transmission mechanism. When the water baffle contacts the sealing strip, the sealing plate can be brought into contact with the water baffle through the arrangement of the connecting plate and the transmission plate, thereby sealing the side of the water baffle and achieving a sealing effect between the water baffle and the frame. When the water baffle is separated from the sealing strip, the sealing plate can be separated from the water baffle through the arrangement of the spring, thereby effectively avoiding the situation in which the sealing plate and the water baffle generate continuous contact friction when the water baffle is raised or lowered, thereby reducing the wear of the sealing plate as well as the resistance and energy consumption during raising or lowering.

[0025] See also Figures 1 to 4 , the utility model provides a technical solution:

[0026] A flood control device for a water conservancy project, comprising a frame 1, and further comprising:

[0027] The water blocking mechanism 2 is provided on the outer surface of the frame 1 and is used to block water flow;

[0028] The sealing mechanism 3 is provided at the inner bottom of the frame 1 and contacts the water blocking mechanism 2 to seal the water blocking mechanism 2;

[0029] The transmission mechanism 4 is arranged on the inner side of the frame 1 , the transmission mechanism 4 is fixedly connected to the water blocking mechanism 2 , and the transmission mechanism 4 is in contact with the sealing mechanism 3 for driving the sealing mechanism 3 .

[0030] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the water blocking mechanism 2 includes a multi-stage hydraulic cylinder 21 arranged on the outer surface of the frame 1 , and a water baffle 22 is provided at the output end of the multi-stage hydraulic cylinder 21 , and the water baffle 22 is slidably connected to the frame 1 .

[0031] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the sealing mechanism 3 includes a sealing strip 31 arranged at the bottom inner side of the frame 1, the sealing strip 31 is in contact with the water baffle 22, and two sealing plates 32 are slidingly provided on the inner surface of the frame 1, both of which are in contact with the water baffle 22. The outer surface of the sealing plate 32 is provided with a spring 33, and the spring 33 is fixedly connected to the frame 1.

[0032] Specifically, such as Figure 2 、 Figure 3 and Figure 4 As shown, there are multiple springs 33 , which can provide sufficient restoring elastic force for the sealing plate 32 , thereby facilitating the separation of the water retaining plate 22 from the sealing plate 32 .

[0033] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the transmission mechanism 4 includes two connecting plates 41 arranged on the inner side of the frame 1. The two connecting plates 41 are fixedly connected to the water baffle 22. A transmission plate 42 is provided on the lower surface of the connecting plate 41. The transmission plate 42 contacts the sealing plate 32.

[0034] Specifically, such as Figure 4 As shown, the upper surface of the sealing plate 32 and the lower surface of the transmission plate 42 are both inclined surfaces, and are at an angle of 30° to the horizontal plane. When the transmission plate 42 contacts the sealing plate 32, the transmission plate 42 can move relatively smoothly.

[0035] Specifically, such as Figure 2 、 Figure 3 and Figure 4 As shown, two buffer blocks 5 are provided on the outer surface of the sealing plate 32 away from the spring 33. The buffer blocks 5 provide buffering protection to the sealing plate 32 when the sealing plate 32 is reset.

[0036] Working principle: When in use, the multi-stage hydraulic cylinder 21 is started, and the output end of the multi-stage hydraulic cylinder 21 extends to drive the water baffle 22 to descend, and then the connection plate 41 and the transmission plate 42 are driven to descend by the water baffle 22. When the transmission plate 42 contacts the sealing plate 32, it drives the two sealing plates 32 to move toward each other. When the water baffle 22 contacts the sealing strip 31, the sealing plate 32 can contact the side of the water baffle 22, completing the sealing of the bottom and side of the water baffle 22, and then completing the water flow blocking.

[0037] After use, the multi-stage hydraulic cylinder 21 is started, and the output end of the multi-stage hydraulic cylinder 21 contracts to drive the water baffle 22 to rise, and then the water baffle 22 rises to drive the connecting plate 41 and the transmission plate 42 to rise. Through the elastic force of the spring 33, when the transmission plate 42 rises, the two sealing plates 32 can move in the opposite direction and separate from the side surface of the water baffle 22 to reset. In this process, the buffer block 5 is set to provide buffer protection for the reset sealing plate 32.
