[0002] The dam water gate is a device used in water conservancy projects to intercept water flow, control water level, regulate flow, and remove sediment and floating objects. The gate is mainly composed of three parts: the movable part (gate leaf), the embedded part, and the opening and closing mechanism. The gate leaf includes the load-bearing structure, walking support, support arm, support hinge, water stop device, lifting lug, etc.; the embedded part includes the track, hinge seat, water stop seat, corner guard, etc.; the opening and closing mechanism is used to control the opening and closing of the gate.

[0003] However, the existing dam body water retaining gates do not have the ability to adaptively change their cross-sections. When adjusting the water level and flow, the gates cannot automatically adjust their cross-section size according to changes in water flow conditions, thereby limiting their adaptability under complex water flow conditions. Due to the lack of the ability to adaptively change their cross-sections, the gates cannot achieve the best effect when adjusting the water level and flow, affecting the overall efficiency and benefits of the water conservancy project; and the existing dam body water retaining gates are easily worn and damaged due to long-term direct impact of water flow. The service life of the gates is short and the stability is not ideal. Correspondingly, more frequent maintenance is required, and the maintenance cost is also high.

[0004] To this end, we provide a dam water retaining gate with an adaptive variable cross-section to solve the above-mentioned problems. Summary of the invention

[0026] 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.

[0027] Embodiment 1

[0028] In order to solve the problem that the existing water-blocking gates do not have the ability to adapt to the changing cross-section, it is difficult to adjust the cross-section size based on the water flow information in the reservoir, and the water flow control and gate stability are not ideal, please refer to Figure 1-Figure 3The utility model provides an adaptive variable-section dam water-blocking gate, comprising a plurality of door panels 1 located between two dam bodies and a plurality of lifting modules 2 respectively located above each door panel 1 for driving the door panels 1 to rise and fall, longitudinal slide grooves and longitudinal slide rails are respectively arranged on the narrow end surfaces on both sides of the door panels 1, and adjacent door panels 1 are slidably matched through the longitudinal slide grooves and the longitudinal slide rails; a cross-section adjustment component 3 is movably provided on the door panel 1; the cross-section adjustment component 3 comprises an adjustment block 301 and an adjustment plate 302 located at the water-facing side of the adjustment block 301, an inflatable rubber sleeve 303 is coated on the water-facing side of the adjustment plate 302, and the inflatable rubber sleeves 303 of adjacent cross-section adjustment components 3 abut against each other, and the setting of the inflatable rubber sleeves 303 enables the adjustment plates 302 to be better sealed to prevent water from flowing out from the gaps of the adjustment plates 302; a hydraulic cylinder 101 for driving the adjustment block 301 to move is fixedly provided on the backwater side of the door panel 1 through a bracket. A plurality of retractable cross-section adjustment components 3 can be adjusted so that the water retaining gate has the ability to adaptively change its cross-section. The cross-section size can be adjusted based on the water flow information in the reservoir to achieve the purpose of optimizing water flow control and improving gate stability.

[0029] When in use, based on the water flow information in the reservoir, such as water flow conditions, water level changes, etc., the adjustment block 301 is controlled to move through the hydraulic cylinder 101, and the adjustment blocks 301 of different door panels 1 are controlled to the required position, so as to realize the change of the cross section. For example, when the water gate is in a fully closed state, the multiple adjustment plates 302 located on the water-facing side of the door panel 1 can be adjusted to be adjusted into an arch together, so that the impact force of the water flow on the gate can be effectively dispersed, and the overall stability of the gate can be improved. The curvature of the arch can also be adjusted based on the actual situation. For example, when the water gate opens the required number of door panels 1 based on the actual water level, the multiple adjustment plates 302 located on the water-facing side of the door panel 1 in the closed state can be adjusted to make the adjustment plates 302 on both sides of the opening together Adjust into an arc shape, gradually extending from the dam body position to the opening, so that the flow state of water when passing through the gate can be effectively improved, the generation of turbulence and eddy currents can be reduced, and the scouring and wear of the gate by water flow can be reduced, and the passing efficiency of water flow can also be improved.

[0030] In order to improve the stability of the cross-section adjustment assembly 3, the water flow control is optimized, such as Figure 4-Figure 5As shown, the cross-section adjustment assembly 3 also includes an angle adjustment unit 304 located on the backwater side of the adjustment plate 302 for adjusting the water-facing angle of the adjustment plate 302; the angle adjustment unit 304 includes an articulated seat 304a and a support 304b fixed on the adjustment plate 302 and rotatably arranged in the articulated seat 304a, and a first motor 304c for driving the support 304b to rotate is arranged on the top of the articulated seat 304a. When the first motor 304c is started, the first motor 304c drives the support 304b to rotate, and the support 304b drives the adjustment plate 302 to rotate, so that the water-facing angle of the adjustment plate 302 can be freely adjusted to adapt to different use environments, and when multiple adjustment plates 302 are spliced, their ends can transition more smoothly.

[0031] In order to reduce the impact of water flow on the regulating plate 302 and protect the regulating plate 302 from damage, Figure 4 As shown, the cross-section adjustment assembly 3 also includes a buffer unit 305 located in the inner cavity of the water-facing side of the adjustment block 301; the buffer unit 305 includes a plurality of movable rods 305a fixed on the hinge seat 304a at equal intervals and a spring 305b fixed at the end of the movable rod 305a; the water-facing side of the adjustment block 301 is provided with a plurality of circular grooves 301a for the movable rods 305a to be inserted movably and at equal intervals, and the water-facing side of the adjustment block 301 is also provided with a cover plate 301b for limiting the movable rods 305a from sliding out. When the water flow impacts the adjustment plate 302, the adjustment plate 302 applies pressure to the hinge seat 304a, the hinge seat 304a applies pressure to the movable rod 305a, and the movable rod 305a applies pressure to the spring 305b, and the spring 305b effectively absorbs and disperses the impact force of the water flow, slows down the water flow speed, and reduces the impact of the water flow on the adjustment plate 302, thereby protecting the adjustment plate 302 from damage.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, in order to solve the problem of easy leakage between multiple door panels 1 and between the door panel 1 and the cross-section adjustment component 3, as shown in FIG. Figure 6-Figure 7 As shown, it also includes a water-stop assembly 4 located on the back water side of the door panel 1, and the water-stop assembly 4 includes a mounting plate 401 and a first inflatable water-stop pad 402 and a second inflatable water-stop pad 403 respectively fixed on the mounting plate 401; the first inflatable water-stop pad 402 is used to seal the gap between adjacent door panels 1, and the second inflatable water-stop pad 403 is used to seal the gap between the door panel 1 and the adjustment block 301; the upper end of the mounting plate 401 is rotatably arranged between the two dam bodies through a rotating shaft, and a second motor 404 for driving the mounting plate 401 to rotate is provided on the side of the mounting plate 401.

[0034] When in use, before the water gate is opened, the second motor 404 drives the mounting plate 401 to rotate upward, so as to prevent the water stop component 4 from affecting the flood discharge. After the water gate is closed, the second motor 404 drives the mounting plate 401 to rotate downward until the mounting plate 401 is parallel to the door panel 1, and gas is filled into the first inflatable water stop pad 402 and the second inflatable water stop pad 403. The first inflatable water stop pad 402 seals the gap between the adjacent door panels 1, and the second inflatable water stop pad 403 seals the gap between the door panel 1 and the adjustment block 301.

[0035] 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.
