Description

[0001] The utility model relates to the technical field of water conservancy project interception, in particular to a blocking device used for water conservancy project interception. Background Art

[0002] Water conservancy projects can be divided into the following categories according to their purpose or service objects: flood control projects that prevent flood disasters; farmland water conservancy projects that prevent drought, waterlogging and waterlogging and serve agricultural production, or irrigation and drainage projects; hydroelectric power generation projects that convert water energy into electrical energy; waterway and port projects that improve and create shipping conditions; and urban water supply and drainage projects that serve industrial and domestic water use and treat and discharge sewage and rainwater.

[0003] There are many existing technologies for interception devices, such as:

[0004] Chinese patent publication number CN113605308A discloses a flow interception device for water conservancy projects and its use method, which relates to the technical field of flow interception devices. The utility model includes a mounting frame, a connecting piece and an interception plate; the connecting piece and the mounting frame are slidably matched; the rotating shaft and the connecting sleeve are rotatably matched; the cross-clip slot is clamped and matched with a transmission assembly; the transmission assembly and the driving gear are meshed and matched with a transmission chain; the placement groove is slidably matched with a sealing plate; the rotating rod is rotatably matched with a ground anchor assembly. The utility model starts the first hydraulic cylinder and the second hydraulic cylinders at both ends to drive each interception plate and the ground anchor assembly into the water together, until the counterweight plate is inserted into the riverbed, starts the first threaded column, pushes the connector to move downward along the mounting frame, and inserts the L-shaped ground anchor rod deeper into the riverbed to improve the stability of the device; starts each third hydraulic cylinder to reset each sealing plate, starts the drive motor, drives the drive gear to rotate, thereby driving the rotation of the transmission chain, and makes each interception plate rotate to achieve the control of water flow.

[0005] It can be seen that when intercepting water conservancy projects, in order to prevent the interception plate from being washed away by the turbulent water flow, each interception plate is often adjusted to be parallel to the flow direction of the water flow before interception to reduce the resistance of the interception plate. However, since the interception is to converge from both sides to the middle, when the water flow is intercepted to the point of being closed, the water retaining dams on both sides are usually in an inverted trapezoidal shape, and the interception plates are vertical. This will cause part of the water flow to flow away between the interception plate and the dam body, which not only affects the interception effect, but also the water flow on both sides will cause scouring to the dam body, which can easily cause the dam body to collapse, and after the interception device blocks the water flow, it cannot be withdrawn to intercept other interception points.

[0021] 4. In the intercepting device used for intercepting water conservancy projects, when the drainage hole is completely blocked, the water flow in the external blocking area is drained through the drainage pipe, thereby reducing the pressure of the water flow on the drainage plate, thereby protecting the drainage plate and the intercepting plate.

[0040] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] like Figure 1 and Figure 2 As shown, a blocking device for intercepting water in a water conservancy project is provided, comprising a frame 100, a plurality of lifting rings are symmetrically arranged on the upper surface of the frame 100, the top of the frame 100 is open, and a drainage part 200 for controlling water flow is symmetrically arranged inside the frame 100, an inner blocking area is formed between the drainage parts 200 on both sides, the drainage part 200 rotates outward, driving the interception part 300 arranged at the end of the drainage part 200 to approach the inner wall of the frame 100, and the interception part 300 is used to An outer sealing area is formed on the outer side of the drainage part 200, and the stones in the inner sealing area are squeezed. The intercepting parts 300 arranged on the inner sides of the drainage parts 200 on both sides are connected to the water flow in the outer sealing area. Under the action of the water flow, the intercepting part 300 is used to completely block the outer sealing area, and the intercepting part 300 is used to provide support for the drainage part 200, so that the stones in the inner sealing area are close to the drainage part 200, and then the stones are filled into the outer sealing area to achieve the interception of the water flow.

[0044] It should be noted that the inner blocking area referred to above is the angle between the drainage parts 200 on both sides, and the outer blocking area is the area between the outer side of the drainage part 200 and the inner wall of the frame 100 .

[0045] It can be seen that when intercepting the water flow, the whole is first lifted to the interception point, and the flow rate of the water flow is controlled by the drainage part 200. Then, the inner blocking area is first filled with stones. Secondly, the drainage parts 200 on both sides drive the interception part 300 to approach the inner wall of the frame 100, so that the water pressure in the outer blocking area is increased. The water flow in the outer blocking area pushes the interception part 300 to completely block the water flow flowing through the outer blocking area, and the guided water flow is used to support the drainage part 200 until the outer blocking areas on both sides are also completely filled with stones. Finally, the frame 100 is reserved at the interception point, and the remaining components are all lifted out.

[0046] The purpose of doing this is: not only to reduce the resistance encountered by the drainage part 200 when intercepting the flow, but also to make the frame 100 fit with the dam bodies on both sides of the interception point to prevent the dam bodies from being washed away by the water flow. Moreover, by intercepting the water flow at the interception point in steps, the water flow is gradually cut off to avoid the impact force of the water flow acting completely on the blocking stones at once, causing the blocking stones to be washed away by the water flow and affecting the blocking effect.

[0047] Considering that the frame 100 encounters greater resistance when it is just placed in the interception point, a plurality of ground anchor assemblies can be arranged directly below the frame 100 (the ground anchor assemblies are prior art and will not be described in detail here). The ground anchor assemblies can be used to increase the stability of the frame 100 and prevent the impact force of the water flow from causing the frame 100 to tilt, thereby ensuring the stability of the frame 100.

[0048] Furthermore, based on the above structure, Figure 3 The structure of the drainage part 200 is first disclosed. The drainage part 200 includes drainage plates 210 rotatably connected to the frame 100 on both sides. The drainage plates 210 on both sides are in a horizontal "V" shape under normal conditions, and one end of the drainage plate 210 away from the frame 100 and the rotation connection therewith is rotatably connected to the telescopic part of the hydraulic rod 201. One end of the hydraulic rod 201 is rotatably connected to the top plate above the frame 100. The top plate and the main body of the frame 100 are detachably connected. Before the frame 100 is hoisted to the interception point, the angle between the drainage plates 210 is first adjusted to the minimum by the hydraulic rods 201 on both sides, so that when the drainage plates 210 are immersed in the water flow, the force of the water flow on the drainage plates 210 can be slowed down to prevent the frame 100 from shaking excessively and affecting the fit between the frame 100 and the two sides of the dam body.

[0049] Then, the inner blocking area is filled with stones first. In order to prevent the accumulated stones from sliding around, an auxiliary plate 220 is rotatably connected to the inner side of the guide plate 210. The auxiliary plates 220 on both sides are used to cooperate with the guide plates 210 on both sides to limit the stones in the inner blocking area, so that the inner blocking area is filled with stones. At this time, the filled stones play a certain supporting role on the guide plates 210 on both sides, reducing the tension on the hydraulic rod 201.

[0050] At the same time, water flows from the outer blocking area to the other side of the frame 100 (refer to Figure 2 As shown), when the stones in the inner blocking area are filled, the hydraulic rod 201 pulls the guide plate 210 to rotate, so that the angle between the guide plates 210 on both sides increases. In this process, the interception part 300 gradually blocks the outer blocking area under the fluctuation of the guide plate 210, so as to facilitate the later blocking work of the outer blocking area.

[0051] Below Figure 3 Based on the combination of Figure 4 As shown, the specific structure of the interception part 300 is disclosed. The interception part 300 is arranged at the end of the guide plate 210. The interception part 300 includes an interception plate 310 with a plurality of drainage holes 311. The drainage holes 311 are used to discharge the water flow in the outer blocking area when the interception plate 310 is matched with the frame 100. The interception plate 310 is slidably connected to the slide rail 110, and the slide rail 110 is plugged into the frame 100. Blocks are symmetrically arranged on one side of the interception plate 310 close to the outer blocking area. When the guide plate 210 is pushed outward, the block is abutted against the guide plate 210, so that the interception plate 310 approaches the inner wall of the frame 100 until it is matched with the inner wall of the frame 100.

[0052] In the above process, the use of multiple drainage holes 311 can prevent the outer blocking area from being completely blocked. The pressure on the interception plate 310 will increase due to the action of the water flow. In this way, the water flow in the inner blocking area can be discharged from one side to the other side, reducing the pressure on the interception plate 310, thereby protecting the interception plate 310.

[0053] When the angle between the drainage plates 210 on both sides gradually increases, the stones in the inner blocking area are gradually separated from the drainage plates 210. In this way, when the drainage plates 210 are lifted at a later stage, the gap between the outer blocking area and the inner blocking area is larger, causing too much water to flow out of the gap, affecting the interception effect.

[0054] To this end, the interception plate 310 is fixedly connected to the traction rope 320 of the interception plate 310, the traction rope 320 is symmetrically distributed up and down, and the other end of the traction rope 320 is fixedly connected to the interception box 330, the two sides of the interception boxes 330 are slidably connected to the connecting piece 331, and the slider 303 fixedly connected to one side of the interception box 330 slides in the slide groove opened in the drainage plate 210. On the other hand, an auxiliary support plate is fixed to one side of the slide rail 110, and the auxiliary support plate is rotatably connected to the vertical pole, and the vertical pole is coaxially connected to two auxiliary wheels 321, and the auxiliary wheels 321 are adapted to the corresponding traction rope 320. Therefore, when the interception plate 310 slides outward, the interception plate 310 pulls the traction rope 320, and the interception box 330 slides along the inner side of the drainage plate 210. The interception boxes 330 on both sides cooperate with the connecting piece 331 to push the stones in the inner blocking area, so that the stones fit the inner side of the drainage plate 210 again, thereby reducing the gap between the inner blocking area and the outer blocking area, so as to intercept the flow later.

[0055] In order to ensure that the interception box 330 can be restored to the initial state after the interception (that is, the state in which the interception boxes 330 on both sides completely wrap the connecting piece 331), the Figure 4 and Figure 5 As shown, a baffle ring 301 is fixedly connected in the slide groove opened in the guide plate 210, and the baffle ring 301 is slidably connected to the traction rope 320. The traction rope 320 is located on the side of the baffle ring 301 close to the interception box 330 and is provided with a first spring 302. The first spring 302 is sleeved on the traction rope 320, and the elastic potential energy of the first spring 302 is used to push the interception box 330 to restore it to its initial state for later reuse.

[0056] When the external blocking area is blocked, as the stones are stacked against the intercepting plate 310, the drainage holes 311 are gradually blocked, which increases the pressure on the drainage plate 210. In order to reduce the pressure on the drainage plate 210, when the drainage holes 311 are completely blocked, the water flow in the external blocking area is drained through the intercepting part 300, thereby reducing the pressure of the water flow on the drainage plate 210.

[0057] Therefore, in Figure 4 Based on and combined with Figure 8 As shown, the specific structure of the blocking part 400 is disclosed. The blocking part 400 is arranged between the guide plates 210 on both sides. The blocking part 400 includes a blocking plate 410 and a drain pipe 420. The blocking plate 410 is fixedly connected to the piston rod. The piston head coaxially connected to the piston rod is sleeved to fit the drain pipe 420, and a second spring 411 is sleeved on the piston rod. On the other hand, the drain pipe 420 is symmetrically connected to the two sides with a bellows 430. The bellows 430 is connected to the through hole opened in the guide plate 210, and a pressure relief valve (at Figure 8 Based on and combined with Fig. 9In this way, when the drain hole 311 is blocked, the water pressure in the blocking area breaks through the pressure relief valve, and the bellows 430 guides the water flow in the outer blocking area to the inside of the drain pipe 420, and uses the water flow to push the piston head to move.

[0058] Combination Figure 6 and Figure 7 As shown, the blocking plate 410 and the drainage hole 311 are fitted together, and the blocking plate 410 is slidably connected to the slide rail 110. When the blocking plate 410 and the intercepting plate 310 completely overlap, the blocking plate 410 blocks the drainage hole 311 to limit the water flow from the drainage hole 311. At the same time, the blocking plate 410 also supports the intercepting plate 310 to improve the resistance of the intercepting plate 310 to the water flow.

[0059] It should be noted that during the movement of the intercepting plate 310 and the blocking plate 410 , the blocking plate 410 is always in contact with the intercepting plate 310 so as to provide support for the intercepting plate 310 .

[0060] Considering that the water drained in the drain pipe 420 needs to be discharged, a push block 440 is provided at the other end of the drain pipe 420. The circular plate fixedly connected to the push block 440 is matched with the drain pipe 420. A pressure relief valve is provided at the connection between the bellows 430 and the drain pipe 420 near the push block 440. The pressure relief valve is connected to the inside of the drain pipe 420. When the water pressure inside the drain pipe 420 increases, the water flow will push the circular plate to move aside, and the water flow will flow out of the pressure relief valve. The push block 440 pushes the auxiliary plate 220 to squeeze the stones in the inner blocking area (combined with Figure 3 As shown), the gap between the stone and the guide plate 210 is reduced to improve the interception effect of the water flow.

[0061] In addition, the push block 440 supports the auxiliary plate 220, and the auxiliary plate 220 supports the guide plate 210, so that the intercepting plate 310 and the frame 100 are closely fitted to prevent water from overflowing from the gap.

[0062] Finally, when the outer and inner sealing areas are filled with stones, the top plate is removed, the steel wire rope is tied to the top plate, the guide plate 210 and the lifting rings on the slide rail 110, and the whole is pulled out, so that the bottom of the frame 100 remains at the interception point, and then the water flows along the gap between the inner and outer sealing areas. At this time, the water flow rate is relatively small, and it can be blocked with stones.

[0063] In summary, the working principle of this scheme is as follows: first, the frame 100 is hoisted to the interception point of the dam body on both sides, and then the flow rate of water from the outer blocking area is controlled by adjusting the angle between the guide plates 210 on both sides, and stones are filled into the inner blocking area.

[0064] Next, when the inner sealing area is filled with stones, the drainage plates 210 on both sides expand outward until the interception plate 310 blocks the outer sealing area. In this process, the interception box 330 cooperates with the connecting piece 331 to squeeze the stones in the inner sealing area, and then fills the outer sealing area with stones. As the number of stones increases, the water flow in the outer sealing area flows into the drainage pipe 420, which on the one hand closes the blocking plate 410 and the interception plate 310 to block the drainage hole 311. On the other hand, under the action of the water flow, the push block 440 pushes the auxiliary plate 220 to squeeze the stones in the inner sealing area again, so that the stones fit tightly with the drainage plates 210 on both sides, thereby reducing the gap between the inner sealing area and the outer sealing area to improve the sealing effect.

[0065] Finally, after the device to be blocked is withdrawn, the gap between the inner blocking area and the outer blocking area can be filled.

[0066] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
