Description

Technical Field

[0001] This utility model relates to the technical field of dam water-stopping equipment, specifically an adjustable water-stopping device for dam seepage prevention. Background Technology

[0002] Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production. In large cities, due to land constraints, flood control walls along riverbanks are generally vertical. To facilitate communication between the inside and outside of the flood control walls and for aesthetic purposes, different types of sluice gates are installed on them. These gates are typically used to control water flow, especially during floods when the water flow is fast and the pressure is high, making the sealing of the sluice gates even more crucial.

[0003] Existing gate seals typically rely on the gate's own weight for downward pressure. Over time, the sealing strips wear down, affecting the sealing effect. Furthermore, when the gate is opened, flowing water can easily carry sand and gravel debris into the grooves of the gate pier, causing them to accumulate. When the gate is lowered, the accumulated sand and gravel debris can affect the sealing and water-stopping effect, leading to water leakage and poor efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable water-stopping device for dam seepage prevention, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An adjustable water-stopping device for dam seepage prevention includes: The gate frame has a base plate fixed to its bottom and a gate assembly is provided on the gate frame. The gate frame has two grooves, and the grooves are provided with sliding grooves and two rectangular slots. The seepage prevention mechanism is installed on the gate frame and is used for sealing and seepage prevention between the gate frame and the gate assembly.

[0006] Furthermore, the gate assembly includes a screw hoist, which is fixedly connected to the gate frame. A screw is installed on the screw hoist, and the bottom of the screw passes through the gate frame and is fitted with the gate body. The two ends of the gate body are located inside two grooves respectively.

[0007] Preferably, both ends of the gate body are rotatably connected to multiple pulleys.

[0008] Furthermore, the seepage prevention mechanism includes: The protective shell is fixed to the top of the gate frame, and ventilation ports are provided at both ends of the protective shell. A rectangular shell is fixedly connected to the bottom of the protective shell. An electric control valve is connected and fixed on the rectangular shell, and a pressure sensor is installed and fixed on the rectangular shell. Both ends of the rectangular shell are provided with sealing components and plugging components. Both air pump one and air pump two are fixedly connected to the protective shell. The air inlet end of air pump one and the air outlet end of air pump two are both connected to and fixedly connected to the delivery pipe, and the delivery pipe is connected to and fixedly connected to the rectangular shell.

[0009] Preferably, a filter screen is installed and fixed inside the air exchange port.

[0010] Preferably, the sealing assembly includes an electrically controlled valve two, one end of which is connected and fixed to a rectangular shell, and the other end of which is connected and fixed to a connecting pipe one. One end of the connecting pipe one is connected and fixed to a connecting pipe two, and both ends of the connecting pipe two pass through the side wall of the gate frame and extend into the interior of the corresponding rectangular groove. An airbag one is provided at the bottom of both ends of the connecting pipe two, and the valve on the airbag one is connected and fixed to the connecting pipe two. One side of the airbag one is fixed to the inner side wall of the corresponding rectangular groove one, and a sliding frame is bonded and fixed to the other side of the airbag one. The sliding frame is slidably connected to the corresponding rectangular groove, and a sealing gasket is bonded and fixed to one side of the sliding frame.

[0011] Preferably, the sealing component includes: One end of the electric control valve is connected and fixed to the rectangular shell, and the other end of the electric control valve is connected and fixed to the connecting pipe three. One end of the connecting pipe three passes through the side wall of the gate frame and extends into the corresponding slide groove. The movable frame is slidably connected to the corresponding groove. An airbag is glued and fixed to the inner wall of the movable frame, and the airbag is glued and fixed to the inner wall of the corresponding groove. The valve on the airbag is connected and fixed to one end of the corresponding connecting pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting an anti-seepage mechanism on the gate frame and starting the screw hoist to move the gate body, the gate can be closed. When the gate body is closed, the second air pump is started and the two second electric control valves are opened to inflate the first airbag. The inflated first airbag pushes the sliding frame and the sealing gasket to move, and the sealing gasket can press against the gate body to seal the gap between the two ends of the gate body and the two grooves, thereby improving the anti-seepage effect when the gate body is closed. By installing an airbag II on the movable frame, when the gate body is opened, the air pump II is activated and two electrically controlled valves III are opened, thereby inflating the airbag II through the connecting pipe III. The inflated airbag II pushes the movable frame to move. The movable frame slides and connects with the bottom of the inner side of the groove, thereby sealing the bottom of the groove after the movable frame moves. This prevents mud, sand and gravel from accumulating at the bottom of the inner side of the groove when the gate is opened to release water, which would affect the closing effect of the gate body and thus affect the water-stopping effect of the adjustable water-stopping device for seepage prevention of the dam.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7In this embodiment of the present invention, an adjustable water-stopping device for dam seepage prevention includes: a gate frame 110 and a seepage prevention mechanism 200. The bottom of the gate frame 110 is fixedly connected to a base plate 120, and a gate assembly is provided on the gate frame 110. Two grooves 111 are provided on the gate frame 110, and a sliding groove 112 and two rectangular grooves 113 are provided inside the grooves 111. The seepage prevention mechanism 200 is provided on the gate frame 110 and is used for sealing and seepage prevention between the gate frame 110 and the gate assembly.

[0017] Specifically, when the adjustable water-stopping device for seepage prevention of the dam body is installed on the flood control dam body 100, the gate frame 110 and gate assembly can be used to seal the gate opening for water prevention, and the opening height of the gate can be adjusted as needed. The seepage prevention mechanism 200 can ensure the sealing effect when the gate assembly is closed to prevent water seepage. Example 1

[0018] like Figure 2-6 As shown, in this embodiment, the gate assembly includes a screw hoist 130, which is fixedly connected to the gate frame 110. A screw is installed on the screw hoist 130, and the bottom of the screw passes through the gate frame 110 and is fitted with a gate body 131. The two ends of the gate body 131 are respectively located inside two grooves 111. Multiple pulleys 132 are rotatably connected to both ends of the gate body 131. The seepage prevention mechanism 200 includes a protective shell 210 and a rectangular shell 22. 0. Air pump 1 230 and air pump 240, protective shell 210 is fixedly connected to the top of gate frame 110, and air exchange ports are opened at both ends of protective shell 210. Rectangular shell 220 is fixedly connected to the bottom of protective shell 210. Solenoid valve 1 221 is connected and fixed on rectangular shell 220, and pressure sensor 222 is installed and fixed on rectangular shell 220. Sealing components and sealing components are provided at both ends of rectangular shell 220. Air pump 1 230 and air pump 240 are both fixedly connected to protective shell 210. Both the air pump 230 (inlet end) and air pump 240 (outlet end) are connected and fixed with a delivery pipe 250, which is also connected and fixed to the rectangular shell 220. The sealing assembly includes a second electrically controlled valve 260, one end of which is connected and fixed to the rectangular shell 220, and the other end of which is connected and fixed with a first connecting pipe 261. One end of the first connecting pipe 261 is connected and fixed with a second connecting pipe 262, and both ends of the second connecting pipe 262 pass through the gate frame 110. The sidewalls extend into the corresponding rectangular grooves 113. Airbags 263 are provided at the bottom of both ends of the connecting pipe 262. The valves on the airbags 263 are connected and fixed to the connecting pipe 262. One side of the airbags 263 is fixed to the inner sidewall of the corresponding rectangular groove 113. A sliding frame 264 is bonded and fixed to the other side of the airbags 263. The sliding frame 264 is slidably connected to the corresponding rectangular groove 113. A sealing gasket 265 is bonded and fixed to one side of the sliding frame 264.

[0019] In this embodiment, by activating the screw hoist 130, the screw and gate body 131 are moved, thereby achieving the closing and shut-off of the gate. Multiple pulleys 132 ensure smoother movement of the gate body 131. When the gate body 131 closes, the second air pump 240 is activated, and air is pumped into the rectangular shell 220 via the air pump 240 and its delivery pipe 250. The first solenoid valve 221 is closed. Then, the two second solenoid valves 260 are opened, and the rectangular shell 220 is closed via the connecting pipes 261 and 262. The gas inside 20 flows into the corresponding airbag 263, causing it to inflate. The inflated airbag 263 pushes the sliding frame 264 and the sealing gasket 265 to move, allowing the sealing gasket 265 to press against the gate body 131, thereby sealing the gaps between the two ends of the gate body 131 and the two grooves 111. Even when the sealing gasket 265 wears down, the inflated airbag 263 keeps it in close contact with the gate body 131, improving the leak-proof effect when the gate body 131 is closed. When all four airbags 263 are fully inflated... Pressure sensor 222 is used to easily sense and detect the pressure inside rectangular shell 220. When the pressure inside rectangular shell 220 gradually increases, two connecting pipes 261 are closed, so that all four connecting pipes 261 can always be in an expanded state. When the gate body 131 needs to be raised and opened, the four airbags 263 are deflated by opening the first solenoid valve 221 and the two second solenoid valves 260. The deflated airbags 263 pull the sliding frame 264 and the sealing gasket 265 to move, so that the sealing gasket 265 separates from the gate body 131, thus avoiding affecting the opening of the gate body 131. Furthermore, by closing the electronic control valve 221 and turning on the air pump 230, the air pump 230 and its delivery pipe 250 are used to draw air into the rectangular shell 220, thereby drawing air into the airbag 263 through the connecting pipe 261 and the connecting pipe 262, causing the airbag 263 to fully contract. The contracted airbag 263 can pull the sliding frame 264 and the sealing gasket 265 to move into the corresponding rectangular groove 113, and limit the sliding frame 264 and the sealing gasket 265 to prevent them from moving out of the rectangular groove 113 when not in use, thus affecting the closing and use of the gate body 131.

[0020] like Figure 5 As shown, in this embodiment, a filter screen 211 is installed and fixed inside the air exchange port.

[0021] In practice, the filter screen 211 is used to prevent foreign objects from entering the interior of the protective shell 210 and affecting the normal use of the anti-seepage mechanism 200. Example 2

[0022] Based on Embodiment 1, in order to avoid the accumulation of mud, sand and gravel at the bottom of the inner wall of the groove 111, which would affect the closing effect of the gate body 131.

[0023] like Figure 5-7 As shown, in this embodiment, the sealing assembly includes: an electrically controlled valve 270 and a movable frame 280. One end of the electrically controlled valve 270 is connected and fixed to the rectangular shell 220, and the other end of the electrically controlled valve 270 is connected and fixed to a connecting pipe 271. One end of the connecting pipe 271 passes through the side wall of the gate frame 110 and extends into the corresponding slide groove 112. The movable frame 280 is slidably connected to the corresponding slide groove 112. An airbag 281 is bonded and fixed to one inner side wall of the movable frame 280, and the airbag 281 is bonded and fixed to one inner side wall of the corresponding groove 111. The valve on the airbag 281 is connected and fixed to one end of the corresponding connecting pipe 271.

[0024] In specific implementation, when the gate body 131 is opened, the second air pump 240 is started, and air is pumped into the rectangular shell 220 through the second air pump 240 and its delivery pipe 250. The first electric control valve 221 is in the closed state. Then, the two third electric control valves 270 are opened, and air is pumped into the second airbag 281 through the third connecting pipe 271. The second airbag 281 expands, and the expanded second airbag 281 pushes the moving frame 280 to move. The moving frame 280 is slidably connected to the bottom of the inner side of the groove 111. Thus, the moving frame 280 seals the bottom of the inner side of the groove 111 after it moves, so as to prevent mud, sand and gravel from accumulating at the bottom of the inner side of the groove 111 when the gate is opened to release water.

[0025] In this invention, to facilitate the operation of the utility model by the operator, a PLC controller can be set up, and the screw gate hoist 130, the first electric control valve 221, the pressure sensor 222, the first air pump 230, the second air pump 240, the second electric control valve 260, and the third electric control valve 270 are all electrically connected to the PLC controller. The PLC controller is prior art and will not be described in detail here.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
