Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic dams, and in particular relates to a hydraulic dam with an automatic flood discharge function. Background Art

[0002] The design of hydraulic dams is relatively simple and the structure is compact, which makes their construction and installation process relatively easy. Compared with traditional sluices or gates, hydraulic dams have a shorter construction period and can be put into use more quickly. Therefore, they are widely used in various scenarios that require flood control, water storage, irrigation, power generation and other functions, such as urban river landscape projects, hydropower station dam weirs, township river water storage, etc.

[0003] Hydraulic dams in the prior art generally include a fixed base, a dam body, and a hydraulic cylinder that drives the dam body to rotate. The dam body does not have an automatic flood discharge structure that can maintain a certain water level. Its flood discharge operation can only be achieved by frequently and accurately adjusting the inclination of the dam body. Accurate adjustment of the inclination of the dam body requires the cooperation of multiple components, such as water level monitors, hydraulic stations, hydraulic cylinders, etc. The overall operation is still relatively cumbersome, and frequent adjustment of the dam body angle through the hydraulic cylinder will also cause greater wear of the hydraulic cylinder and a shorter service life. Utility Model Content

[0004] The purpose of the utility model is to provide a hydraulic dam with automatic flood discharge function in order to solve the above-mentioned problems, aiming to solve the technical problems that the hydraulic dam in the prior art does not have an automatic flood discharge structure that can maintain a certain water level on the dam body, and the flood discharge operation can only be achieved by frequently and accurately adjusting the inclination of the dam body. The overall operation is cumbersome, and it will also cause greater wear and tear on the hydraulic cylinder and a short service life.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A hydraulic dam with an automatic flood discharge function, comprising a base, a dam body rotatably connected to the base, and a hydraulic cylinder driving the base to rotate relative to the dam body, wherein a plurality of automatic flood discharge components are arranged on the dam body from top to bottom;

[0007] The automatic flood discharge component includes a flood discharge outlet opened on the dam body, and a rotating part rotatably connected to the inside of the flood discharge outlet and used to block the flood discharge outlet. The rotating part rotates relative to the flood discharge outlet under the push of water flow to expose a water flow channel for automatic flood discharge. The back surface of the dam body is provided with an adjustable limit component for pressing the rotating part to block the flood discharge outlet.

[0008] As a further optimization solution of the utility model, the rotating member includes a plate body and a hollow cavity arranged on the plate body, and a central axis is opened inside the plate body located above and below the hollow cavity.

[0009] As a further optimization scheme of the utility model, the adjustable limit assembly includes two limit baffles symmetrically arranged on the back water surface of the dam body, a pressure plate slidably connected between the two limit baffles and pressed against the back water surface of the dam body, and a power assembly driving the pressure plate to move up and down;

[0010] The flood discharge outlet is located between two limit baffles. When the rotating member vertically blocks the flood discharge outlet, the back-to-water surface of the rotating member contacts the pressure plate.

[0011] As a further optimization scheme of the utility model, the power assembly includes a fixed plate and a protective box arranged on the back water surface of the dam body, a plurality of screw rods rotatably connected between the fixed plate and the protective box, a nut seat connected to the screw rods through a ball nut pair, a driving motor arranged inside the protective box and rotatably connected to one of the screw rods, and a plurality of synchronizing parts arranged in sequence between two adjacent screw rods, and the nut seat is fixedly connected to the pressure plate.

[0012] As a further optimization scheme of the utility model, the top of the dam body is bent toward the back water surface of the dam body to form an arc-shaped portion for diverting water, and a plurality of support rods are provided between the back water surface of the dam body and the arc-shaped portion, and the fixed plate and the protective box are fixedly connected to the support rods.

[0013] As a further optimization solution of the utility model, a plurality of reinforcing plates are provided below the automatic flood discharge assembly at the bottom on the back water surface of the dam body.

[0014] The beneficial effects of the utility model are:

[0015] 1) The utility model provides the dam body with several automatic flood discharge levels by arranging automatic flood discharge components at different height positions of the dam body. The staff can select different water level positions as the water level positions for automatic flood discharge according to actual needs. By adjusting the pressure plate in the adjustable limit assembly to not press against the back surface of the rotating part, the rotating part will be in the automatic flood discharge state. When the water level reaches the water level position, the rotating part will rotate relative to the flood discharge port under the push of the water flow to expose the water flow channel, and the flood can be automatically discharged. The utility model has a simple structure, multiple flood discharge levels can be selected, and it is convenient to use. It can also reduce the frequent adjustment of the hydraulic cylinder to slow down the wear of the hydraulic cylinder and keep it for a long service life.

[0016] 2) The utility model drives the motor to work and utilizes the synchronization parts to drive all the screw rods to rotate synchronously, so that the nut seat and the pressure plate move up and down along the screw rod. When the pressure plate presses against the back water surface of the rotating part, the rotating part is in a water retaining state, which can be used for water retaining and flood prevention. When the pressure plate does not press against the back water surface of the rotating part, the rotating part is in an automatic flood discharge state, which can be used for automatic flood discharge at this water level position, so as to facilitate switching of the rotating part state to meet different usage requirements.

DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1-5 As shown, a hydraulic dam with automatic flood discharge function comprises a base 1, a dam body 2 rotatably connected to the base 1, and a hydraulic cylinder 3 driving the base 1 to rotate relative to the dam body 2, wherein a plurality of automatic flood discharge components are arranged on the dam body 2 from top to bottom;

[0025] The automatic flood discharge component includes a flood discharge outlet 4 opened on the dam body 2, and a rotating part 5 rotatably connected to the inside of the flood discharge outlet 4 and used to block the flood discharge outlet 4. The rotating part 5 rotates relative to the flood discharge outlet 4 under the push of the water flow to expose the water flow channel for automatic flood discharge. The back surface of the dam body 2 is provided with an adjustable limit component for pressing the rotating part 5 to block the flood discharge outlet 4.

[0026] Preferably, the rotating member 5 includes a plate body 51 and a hollow cavity 53 provided on the plate body 51. A central axis 52 is provided inside the plate body 51 located above and below the hollow cavity 53. The central axis 52 is provided to reduce the weight of the upper and lower ends of the plate body 51. The upper and lower ends of the plate body 51 are easy to rotate relative to the flood discharge outlet 4 under the push of water flow.

[0027] Preferably, the adjustable limit assembly includes two limit baffles 13 symmetrically arranged on the back water surface of the dam body 2, a pressure plate 6 slidably connected between the two limit baffles 13 and pressed against the back water surface of the dam body 2, and a power assembly driving the pressure plate 6 to move up and down;

[0028] The flood discharge outlet 4 is located between two limit baffles 13 . When the rotating member 5 vertically blocks the flood discharge outlet 4 , the back-to-water surface of the rotating member 5 contacts the pressure plate 6 .

[0029] Preferably, the power assembly includes a fixed plate 7 and a protective box 8 arranged on the back water surface of the dam body 2, a plurality of screw rods 9 rotatably connected between the fixed plate 7 and the protective box 8, a nut seat 10 connected to the screw rods 9 through a ball nut pair, a driving motor 11 arranged inside the protective box 8 and rotatably connected to one of the screw rods 9, and a plurality of synchronizing parts 12 arranged in sequence between two adjacent screw rods 9, and the nut seat 10 is fixedly connected to the pressure plate 6.

[0030] It should be noted that, in this embodiment, the synchronous member 12 includes two synchronous wheels respectively arranged between the two screw rods 9, and a synchronous belt arranged between the two synchronous wheels;

[0031] In this embodiment, if there are two screw rods 9 in a power assembly, a synchronous member 12 is provided between the two screw rods 9; if there are three screw rods 9, two synchronous members 12 are provided between two adjacent screw rods 9 in sequence, and so on. Then, one of the screw rods 9 can be driven to rotate by the driving motor 11, and then the other screw rod 9 adjacent to the screw rod 9 can be driven to rotate by the synchronous wheel and the synchronous belt, so as to realize the synchronous rotation of all the screw rods 9, so that the nut seat 10 moves up and down along the screw rod 9 to drive the pressure plate 6 to move up or down.

[0032] In the present application, each automatic flood discharge component arranged at a different height position of the dam body 2 corresponds to a water level position for automatic flood discharge. The staff can select different water level positions as the water level positions for automatic flood discharge according to actual needs, that is, the pressure plate 6 of the automatic flood discharge component at the selected height position is moved up to a position where it does not press against the back water surface of the rotating part 5. When the rotating part 5 is not pressed by the pressure plate 6, the rotating part 5 is easy to rotate relative to the flood discharge outlet 4 under the push of the water flow, thereby failing to block the flood discharge outlet 4 and exposing the water flow channel to achieve the effect of automatic flood discharge.

[0033] It should be noted that, in this embodiment, when the pressure plate 6 presses against the back water surface of the rotating member 5, the rotating member 5 is in a water blocking state, and when the pressure plate 6 does not press against the back water surface of the rotating member 5, the rotating member 5 is in an automatic flood discharge state.

[0034] Preferably, the top of the dam body 2 is bent toward the back surface of the dam body 2 to form an arc-shaped portion for diversion. When the dam body 2 is laid down, the arc-shaped portion can play a certain role in diversion. A plurality of support rods 14 are provided between the back surface of the dam body 2 and the arc-shaped portion. The fixing plate 7 and the protection box 8 are fixedly connected to the support rods 14. The support rods 14 can play a role in strengthening and reinforcing. The fixing plate 7 and the protection box 8 are connected to the support rods 14, which can also increase their support stability.

[0035] Preferably, a plurality of reinforcing plates 15 are provided below the automatic flood discharge assembly at the bottom on the backwater surface of the dam body 2 to strengthen and reinforce it.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the 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.
