Description

Technical Field

[0001] This utility model relates to the field of debris flow prevention and control technology, specifically a debris flow prevention and control device for water conservancy projects. Background Technology

[0002] Debris flows are special types of floods caused by precipitation (heavy rain, glacial meltwater, snowmelt) in valleys or on mountain slopes, carrying large amounts of solid materials such as mud, sand, rocks, and boulders. Their water and sediment collection processes are highly complex, a product of the combined effects of various natural and anthropogenic factors. Debris flows are characterized by their suddenness, high velocity, large flow rate, large material volume, and strong destructive power. Debris flow control devices for water conservancy projects are a series of engineering structures and equipment used to prevent and mitigate the damage caused by debris flows to water conservancy facilities.

[0003] The baffles of existing debris flow control devices used in water conservancy projects do not have angle adjustment function. Due to the difference in terrain slope in different installation areas, debris flow control devices cannot be used for installation on different terrain slopes.

[0004] Therefore, this utility model provides a debris flow prevention device for water conservancy projects to solve the above problems. Utility Model Content

[0005] This utility model provides a debris flow control device for water conservancy projects, aiming to solve the problems mentioned in the background art, such as the baffle of the existing debris flow control device for water conservancy projects not having an angle adjustment function, and the debris flow control device not being suitable for installation and use on different terrain slopes due to the differences in terrain slope in different installation areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a debris flow prevention device for water conservancy projects, comprising a base, a baffle plate rotatably mounted on the end face of the base, and an adjustment structure mounted on the base;

[0007] The adjustment structure includes two sets of threaded rods and threaded sleeves threaded onto the threaded rods. A support rod is rotatably mounted on the end face of the threaded sleeve. A worm gear is mounted on the end of the threaded rod furthest from the baffle. The adjustment structure also includes a worm gear rotatably mounted on a base at both ends via bearings. By setting up the adjustment structure, the angle of the baffle is adjustable, avoiding the problem that existing debris flow control devices in water conservancy projects lack angle adjustment capabilities. This allows the debris flow control device to be installed and used in areas with different terrain slopes, thereby improving the device's operational flexibility.

[0008] Preferably, a buffer structure is installed on the back of the baffle;

[0009] The buffer structure includes a fixed frame installed at the corner of the end face of the baffle. A movable rod is slidably installed on the fixed frame through a connecting hole. A spring is installed on the fixed frame and outside the movable rod. The ends of the four sets of springs away from the baffle are connected by a mounting frame. A wire mesh is installed on the mounting frame.

[0010] Preferably, a support sleeve is symmetrically installed on the end face of the base, and a rotating shaft that is rotatably connected to the inner wall of the support sleeve is installed on the side wall of the baffle.

[0011] Preferably, the base has a sliding groove and a receiving groove. The front and rear sides of the base are rotatably connected to the two ends of the threaded rod through bearings. The two ends of the support rod are rotatably mounted with connecting brackets through connecting holes. The lower connecting bracket is connected to the end face of the threaded sleeve, and the upper connecting bracket is connected to the front face of the baffle. The left end of the worm extends to the outside of the base and is equipped with a throttle handle.

[0012] Preferably, two sets of mounting rings are symmetrically installed on the front and rear side walls of the base, and ground nails are slidably installed on the inner wall of the mounting rings.

[0013] Preferably, the end of the spring away from the fixed frame is connected to the mounting frame, and a limit member is provided at the end of the movable rod located in the inner cavity of the fixed frame.

[0014] Preferably, the mounting frame has a threaded hole at the corner, and a bolt is installed on the mounting frame through the threaded hole. A fixing frame is installed on the mounting frame through the bolt.

[0015] Beneficial effects: By setting up an adjustment structure and using threaded rods, threaded sleeves, struts, worm gears and worms in combination, the angle adjustment function of the baffle is realized, which avoids the problem that the baffles of existing debris flow control devices used in water conservancy projects do not have an angle adjustment function. This allows the debris flow control device to be installed and used in areas with different terrain slopes, thereby improving the flexibility of the device. Attached Figure Description

[0022] 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.

[0023] Example 1

[0024] This embodiment provides a debris flow prevention device for water conservancy projects, such as... Figure 1-5 As shown, the debris flow prevention device includes a base 1, a baffle 2 is rotatably installed on the end face of the base 1, and an adjustment structure 3 is installed on the base 1.

[0025] The adjustment structure 3 includes two sets of threaded rods 31 and threaded sleeves 32 threadedly mounted on the threaded rods 31. A support rod 33 is rotatably mounted on the end face of the threaded sleeve 32. A worm gear 34 is mounted on the end of the threaded rod 31 away from the baffle 2. The adjustment structure 3 also includes a worm 35 rotatably mounted on the base 1 at both ends via bearings.

[0026] In use, by using the mounting ring 5 and the ground nails 6, the base 1 is placed on ground with different slopes. Multiple sets of ground nails 6 are driven into the soil to fix the base 1 in place. Then, the installer rotates the handle 36 clockwise or counterclockwise. The handle 36 drives the worm gear 35 to rotate synchronously. Because the worm wheel 34 and the worm gear 35 are meshed, the worm gear 35 drives the left and right worm wheels 34 to rotate synchronously. The worm wheels 34 drive the threaded rod 31 to rotate clockwise or counterclockwise within the base 1. The threaded rod 31 moves the threaded sleeve 32 forward or backward. The threaded rod 31 is driven by the lower connecting bracket 331, which in turn moves the support rod 33. The support rod 33 then... Driven by the upper connecting frame 331, and because the baffle 2 is rotatably connected to the base 1, the upper connecting frame 331 can adjust the baffle 2 forward or backward, thereby realizing the angle adjustment function of the baffle 2. According to the actual needs of the installation site terrain, the installer can adjust the baffle 2 to the optimal angle for preventing debris flow and then stop turning the handle 36. By adjusting the setting of the structure 3, the problem that the baffle 2 of the existing debris flow prevention device used in water conservancy projects does not have an angle adjustment function is avoided, so that the debris flow prevention device can be installed and used in areas with different terrain slopes, thereby improving the flexibility of the device.

[0027] In this embodiment, a support sleeve 11 is symmetrically installed on the end face of the base 1, and a rotating shaft 21 that is rotatably connected to the inner wall of the support sleeve 11 is installed on the side wall of the baffle 2; a sliding groove 12 and a receiving groove 13 are provided on the base 1, and the front and rear sides of the base 1 are rotatably connected to the two ends of the threaded rod 31 through bearings. The two ends of the support rod 33 are rotatably installed with connecting brackets 331 through connecting holes. The lower connecting bracket 331 is connected to the end face of the threaded sleeve 32, and the upper connecting bracket 331 is connected to the front face of the baffle 2. The left end of the worm 35 extends to the outside of the base 1 and is equipped with a throttle 36.

[0028] In this configuration, the threaded rod 31 and the rotating shaft 21 are installed inside the sliding groove 12, and the worm gear 34 and the worm 35 are installed inside the receiving groove 13, thereby enabling the adjustment structure 3 to be installed and operated normally.

[0029] In this embodiment, two sets of mounting rings 5 ​​are symmetrically installed on the front and rear side walls of the base 1, and ground nails 6 are slidably installed on the inner wall of the mounting rings 5.

[0030] Example 2

[0031] Unlike Example 1, when existing debris flow prevention devices for water conservancy projects are in use, the debris flow containing large-volume rocks will rapidly impact the prevention device at the moment the debris flow occurs, causing the baffle 2 to be damaged by the impact. Therefore, a buffer structure 4 is installed on the back of the baffle 2.

[0032] The buffer structure 4 includes a fixed frame 41 installed at the corner of the end face of the baffle 2. A movable rod 42 is slidably installed on the fixed frame 41 through a connecting hole. A spring 43 is installed on the fixed frame 41 and outside the movable rod 42. The ends of the four sets of springs 43 away from the baffle 2 are connected through a mounting frame 44. A wire mesh 45 is installed on the mounting frame 44.

[0033] In use, when a debris flow impacts the baffle 2, upon contact with the wire mesh 45, large boulders in the debris flow are intercepted by the wire mesh 45, while smaller pebbles and water pass through the wire mesh 45 and impact the baffle 2's blocking surface. This prevents large boulders from directly impacting the baffle 2, allowing the wire mesh 45 and baffle 2 to separately intercept large boulders, small pebbles, and water in the debris flow, thus relieving the baffle 2 of the interception pressure. When the wire mesh 45 is impacted by large boulders, it is driven by the mounting frame 44. 44 drives multiple sets of springs 43 to compress towards the fixed frame 41, providing elastic buffering force for the mounting frame 44 and wire mesh 45, thereby protecting the wire mesh 45 and reducing the impact damage of large stones on the wire mesh 45 to a certain extent. The buffer structure 4 protects the baffle 2, avoiding the problem that the existing debris flow prevention device used in water conservancy projects will be damaged by the rapid impact of the debris flow containing large stones when it occurs. This extends the service life of the debris flow prevention device.

[0034] In this embodiment, the end of the spring 43 away from the fixed frame 41 is connected to the mounting frame 44, and the end of the movable rod 42 located in the inner cavity of the fixed frame 41 is provided with a limiting member 421;

[0035] The setting of the limiting component 421 can prevent the spring 43 from being stretched to the limit, which would cause the movable rod 42 to detach from the fixed frame 41, thus ensuring the stable installation of components such as the wire mesh 45.

[0036] In this embodiment, a threaded hole 441 is provided on the mounting frame 44 at the corner, and a bolt 46 is installed on the mounting frame 44 through the threaded hole 441. A fixing frame 47 is installed on the mounting frame 44 through the bolt 46.

[0037] The wire mesh 45 is fixedly installed between the mounting frame 44 and the fixing frame 47 by means of bolts 46 and fixing frame 47. When the wire mesh 45 is damaged, the bolts 46 can be removed and the fixing frame 47 can be taken off to facilitate the replacement of the wire mesh 45.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
