Description

Technical Field

[0001] The utility model relates to the technical field of dam flow regulation, in particular to a water flow regulating device. Background Art

[0002] Unstable dam seepage can reduce dam slope stability, cause seepage damage to the foundation and structure of earth-rock dams, and cause hydrochemical damage to the foundation and structure of concrete dams. Furthermore, excessive seepage losses reduce project benefits. Therefore, monitoring dam seepage and pressure is crucial to ensuring dam safety.

[0003] In the prior art, flow regulation is required when the dam supplies water to the hydropower station during the flood season and the non-flood season. This can adjust the water flow entering the hydropower station to avoid excessive power generation during the flood season and too little power generation during the non-flood season. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a water flow regulating device capable of regulating the water flow of a dam.

[0005] The utility model is implemented by the following method: a water flow regulating device, including a water dam, a water diversion pipe is provided on the water dam, the water outlet end of the water diversion pipe is connected to the power generation device, a limiting groove is provided on the left side of the water dam, support blocks are provided at the front and rear ends of the water inlet of the water diversion pipe, an opening and closing plate for opening and closing the water inlet of the water diversion pipe is hingedly provided on the support block, a driving member for driving the opening and closing of the opening and closing plate is provided in the limiting groove, and a sealing ring that cooperates with the water inlet of the water diversion pipe is provided on the inner side of the opening and closing plate.

[0006] Furthermore, the driving member includes a multi-section telescopic cylinder, strip openings are provided on the front and rear ends of the opening and closing plate, sliding plates are provided on the upper and lower ends of the opening and closing plate, the sliding plates are connected via connecting rods, and the connecting rods are passed through the strip openings. The multi-section telescopic cylinders are hingedly provided in the limiting grooves, and the ends of the telescopic rods of the multi-section telescopic cylinders are hingedly provided to the sliding plates, and guide wheels are provided on the front and rear ends of the inner side surfaces of the sliding plates.

[0007] The beneficial effects of the present invention are as follows: the present invention adds a driving part and an opening and closing plate to the device, which can adjust the water flow of the dam through the opening and closing plate, and timely adjust the amount of power generation; the present invention has a simple structure and is easy to operate, which can effectively save manpower and material resources and improve work efficiency.

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] See also Figure 1 and Figure 2 As shown, the utility model provides an embodiment: a water flow regulating device, comprising a water retaining dam 1, a water diversion pipe 2 is provided on the water retaining dam 1, the outlet end of the water diversion pipe 2 is connected to a power generation device, a limiting groove 3 is provided on the left side of the water retaining dam 1, and support blocks (not shown) are provided at both the front and rear ends of the water inlet of the water diversion pipe 2. An opening and closing plate 4 for opening and closing the water inlet of the water diversion pipe 2 is hingedly provided on the support block, a driving member 5 for driving the opening and closing of the opening and closing plate 4 is provided in the limiting groove 3, and a sealing ring 41 is provided on the inner side of the opening and closing plate 4 to cooperate with the water inlet of the water diversion pipe 2. The driving member 5 can adjust the opening and closing angle of the opening and closing plate 4, thereby achieving the function of regulating the water outflow of the dam.

[0012] Please continue reading Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the driving member 5 includes a multi-section telescopic cylinder 51. Strip-shaped openings 52 are provided at both the front and rear ends of the opening and closing plate 4. Sliding plates 53 are provided at both the upper and lower ends of the opening and closing plate 4. The sliding plates 53 are connected via a connecting rod 54, which passes through the strip-shaped opening 52. The multi-section telescopic cylinder 51 is hingedly provided in the limiting groove 3. The ends of the telescopic rods of the multi-section telescopic cylinder 51 are hingedly provided with the sliding plates 53. Guide wheels 55 are provided at both the front and rear ends of the inner side of the sliding plates 53. The multi-section telescopic cylinder 51 drives the opening and closing plate 4 to open and close the water inlet of the water diversion pipe 2, thereby adjusting the opening and closing angle and thus regulating the water outflow from the dam.

[0013] The hinge arrangement in the present invention is a hinge method in the prior art, which is clearly understood by those skilled in the art and will not be described in detail here.

[0014] The multi-section telescopic cylinder in the present invention is prior art, which is already clearly understood by those skilled in the art and will not be described in detail here.

[0015] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
