Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically a protective device for slope construction in water conservancy projects. Background Technology

[0002] Slope protection devices for water conservancy projects are safety measures developed to address slope stability issues during construction. These devices primarily consist of anchor bolts and protective netting, designed to prevent landslides, collapses, and other disasters on the slopes during construction, ensuring construction safety and project quality. The protective devices possess excellent impact and corrosion resistance and can be customized to suit different terrains and geological conditions. During construction, these devices effectively reduce construction risks and improve operational efficiency.

[0003] According to the Chinese Utility Model Publication No. CN220953220U, a protective device for slope construction in water conservancy projects is disclosed. This protective device uses a motor to drive a threaded rod to rotate. The threaded rod and the movable column are driven by threaded grooves, thereby extending the protective device. It is convenient to use at different water conservancy project slope construction sites. The first upper frame and the second upper frame are connected by a locking block that is inserted into the locking groove, eliminating the need for repeated use of bolts and facilitating quick installation or disassembly. 1. This slope protection device for water conservancy projects involves a protective net that abuts against the slope to protect it and prevent it from sliding or collapsing. A motor drives a threaded rod to rotate, which in turn extends the protection device through a threaded transmission with a movable column. This allows for convenient use on other water conservancy projects and is suitable for slopes of varying lengths, enhancing the device's practicality. 2. The device also includes a locking mechanism where a rod abuts against the slope and is inserted into the slope to secure it. A locking block is indirectly pushed into a slot via a fixing block, allowing for easy assembly and disassembly. Multiple locking devices joined together provide greater stability to the slope.

[0004] However, there are some issues to consider when implementing the above technical solutions: the lower frame, middle frame and first upper frame of the protective device are not on the same plane, which makes it impossible for the middle frame to fit against the slope during use, causing the slope to be unstable and prone to local collapse, leading to danger. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for slope construction in water conservancy projects, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for slope construction in water conservancy projects, comprising a base, an adjustment mechanism, a support mechanism, and a winding mechanism. The bottom of the base is provided with a fixed anchor rod, the back of the top of the base is provided with an adjustment mechanism, the front of the top of the base is provided with a support mechanism, and the inside of the base is provided with a winding mechanism.

[0007] Preferably, the adjustment mechanism includes a rotating seat, a first bracket, a second bracket, a third bracket, an electric telescopic rod, a telecommunication interface, a limiting block, and a limiting groove. The rotating seat is welded to the top back of the base. The first bracket is hinged to the inner side of the rotating seat. The second bracket is slidably connected to the inner side of the first bracket. The third bracket is slidably connected to the inner side of the second bracket. The first bracket, the second bracket, and the third bracket have the same dimensions.

[0008] Preferably, the interior of the third bracket is fixedly connected to one end of the electric telescopic rod, and the other end of the electric telescopic rod is fixedly connected to the first bracket. A telecommunications interface is provided on one side of the first bracket, and the telecommunications interface is electrically connected to the electric telescopic rod.

[0009] Preferably, the surfaces of the first and third brackets are welded with limiting blocks, and the surface of the second bracket is provided with a limiting groove, the limiting groove being in close contact with the limiting block.

[0010] Preferably, the support mechanism includes a first connecting seat, an adjusting screw, a second connecting seat, and a retaining seat. The first connecting seat is welded to the top front of the base. The outer side of the first connecting seat is bolted to one end of the adjusting screw. The other end of the adjusting screw is bolted to the second connecting seat. The second connecting seat is welded to the first bracket.

[0011] Preferably, a retaining seat is welded to the center of the top front of the base, and the retaining seat is sized to match the adjusting screw.

[0012] Preferably, the winding mechanism includes a rotating shaft, a spring plate, a winding roller, a waterproof cloth, a connecting frame, and a guide roller. The rotating shaft is welded to the center of the base. The surface of the rotating shaft is fixedly connected to one end of the spring plate. The other end of the spring plate is fixedly connected to the winding roller. The surface of the winding roller is fixedly connected to one end of the waterproof cloth. The other end of the waterproof cloth is fixedly connected to the connecting frame. The connecting frame is welded to the third support.

[0013] Preferably, a guide roller is rotatably connected to the inner back of the base, and the guide roller is in close contact with the waterproof cloth.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model features a rotating base, a first support, a second support, and a third support. The first support rotates inside the rotating base to accommodate different slope angles. The second and third supports are the same size as the first support, ensuring that different areas are on the same plane. This prevents the waterproof cloth from failing to adhere to the slope and causing localized collapse that could lead to danger. By setting a limiting block and a limiting groove, the limiting groove and the limiting block can cooperate to prevent misalignment of the first, second, and third supports, which could prevent the waterproof cloth from failing to adhere to the slope. By setting a first connecting seat, an adjusting screw, and a second connecting seat, the adjusting screw is connected to the first and second connecting seats. Rotating the central handle of the screw changes the length of the adjusting screw, thus fixing the angle of the protective device.

[0016] This invention features a rotating shaft, spring plate, take-up roller, waterproof cloth, and connecting frame. When the third support extends, it drives the connecting frame to move, allowing the waterproof cloth to be pulled out from the base. As the waterproof cloth is pulled out, the take-up roller rotates, which applies force to the spring plate. When the third support retracts, the spring plate releases its force and resets, which in turn drives the take-up roller to rotate in the opposite direction to retract the waterproof cloth. By setting a guide roller, the waterproof cloth can be prevented from being damaged due to friction between it and the base. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-4 An embodiment of this utility model is provided: a protective device for slope construction in water conservancy projects, including a base 1, an adjustment mechanism 3, a support mechanism 4 and a winding mechanism 5. The bottom of the base 1 is provided with a fixed anchor rod 2, the back of the top of the base 1 is provided with an adjustment mechanism 3, the front of the top of the base 1 is provided with a support mechanism 4, and the inside of the base 1 is provided with a winding mechanism 5.

[0027] Specifically, the adjustment mechanism 3 includes a rotating seat 301, a first bracket 302, a second bracket 303, a third bracket 304, an electric telescopic rod 305, a telecommunications interface 306, a limiting block 307, and a limiting groove 308. The rotating seat 301 is welded to the top back of the base 1. The first bracket 302 is hinged to the inner side of the rotating seat 301. The second bracket 303 is slidably connected to the inner side of the first bracket 302. The third bracket 304 is slidably connected to the inner side of the second bracket 303. The first bracket 302, the second bracket 303, and the third bracket 304 have the same dimensions. The first bracket 302 rotates inside the rotating seat 301 to match different slope angles. The second bracket 303 and the third bracket 304 have the same dimensions as the first bracket 302, which can ensure that different places are on the same plane, avoiding the waterproof cloth 504 from failing to adhere to the slope and causing local collapse that could lead to danger.

[0028] Specifically, the interior of the third bracket 304 is fixedly connected to one end of the electric telescopic rod 305, and the other end of the electric telescopic rod 305 is fixedly connected to the first bracket 302. A telecommunications interface 306 is provided on one side of the first bracket 302, and the telecommunications interface 306 is electrically connected to the electric telescopic rod 305. The control device is connected to the telecommunications interface 306 to control the extension and retraction of the electric telescopic rod 305, thereby changing the height of the device to match the use of slopes of different heights.

[0029] Specifically, limiting blocks 307 are welded to the surfaces of the first support 302 and the third support 304, and limiting grooves 308 are opened on the surface of the second support 303. The limiting grooves 308 and the limiting blocks 307 are tightly fitted. The cooperation between the limiting grooves 308 and the limiting blocks 307 can prevent the first support 302, the second support 303 and the third support 304 from being misaligned, which would prevent the waterproof cloth 504 from being unable to adhere to the slope.

[0030] Specifically, the support mechanism 4 includes a first connecting seat 401, an adjusting screw 402, a second connecting seat 403, and a retaining seat 404. The first connecting seat 401 is welded to the top front of the base 1. The outer side of the first connecting seat 401 is bolted to one end of the adjusting screw 402. The other end of the adjusting screw 402 is bolted to the second connecting seat 403. The second connecting seat 403 is welded to the first bracket 302. The adjusting screw 402 is connected to the first connecting seat 401 and the second connecting seat 403. By rotating the central handle of the screw, the length of the adjusting screw 402 can be changed to fix the angle of the protective device.

[0031] Specifically, a card holder 404 is welded to the center of the top front of the base 1. The card holder 404 is matched in size with the adjusting screw 402. When storing the protective device, the adjusting screw 402 can be placed on the card holder 404 for easy carrying, while avoiding the adjusting screw 402 from affecting storage.

[0032] Specifically, the winding mechanism 5 includes a rotating shaft 501, a spring plate 502, a winding roller 503, a waterproof cloth 504, a connecting frame 505, and a guide roller 506. The rotating shaft 501 is welded to the center of the base 1. The surface of the rotating shaft 501 is fixedly connected to one end of the spring plate 502. The other end of the spring plate 502 is fixedly connected to the winding roller 503. The surface of the winding roller 503 is fixedly connected to one end of the waterproof cloth 504. The other end of the waterproof cloth 504 is fixedly connected to the connecting frame 505. The connecting frame 505 is welded to the third support 304. When the third support 304 extends, it drives the connecting frame 505 to move, which can pull the waterproof cloth 504 out of the base 1. When the waterproof cloth 504 is pulled out, the winding roller 503 rotates, which can cause the spring plate 502 to be stressed. When the third support 304 retracts, the spring plate 502 releases the force and resets, which can drive the winding roller 503 to rotate in the opposite direction to retract the waterproof cloth 504.

[0033] Specifically, a guide roller 506 is rotatably connected to the back of the base 1. The guide roller 506 is in close contact with the waterproof cloth 504. The guide roller 506 can prevent the waterproof cloth 504 from being damaged due to friction between the waterproof cloth 504 and the base 1.

[0034] Working principle: First, the base 1 is fixed to the slope toe by the anchor rod 2. Then, the first bracket 302 rotates inside the rotating seat 301 to match different slope angles. Next, the adjusting screw 402 is connected to the first connecting seat 401 and the second connecting seat 403. Rotating the center handle of the screw changes the length of the adjusting screw 402 to fix the angle of the protective device. The control device is connected to the telecommunication interface 306 to control the extension and retraction of the electric telescopic rod 305, changing the height of the device to match slopes of different heights. The second bracket 303 and the third bracket 304 are the same size as the first bracket 302, ensuring that different parts are on the same plane. At the same time, the limiting groove 308 and the limiting block 307 cooperate to prevent the first bracket 302 from... The misalignment between the second support 303 and the third support 304 causes the waterproof cloth 504 to fail to adhere to the slope, resulting in a partial collapse and potential danger. When the third support 304 extends, it drives the connecting frame 505 to move, allowing the waterproof cloth 504 to be pulled out of the base 1. When the waterproof cloth 504 is pulled out, the winding roller 503 rotates, which puts force on the spring plate 502. When the third support 304 retracts, the spring plate 502 releases its force and resets, which in turn drives the winding roller 503 to rotate in the opposite direction to retract the waterproof cloth 504. The guide roller 506 can prevent the waterproof cloth 504 from being damaged due to friction between it and the base 1. When storing the protective device, the adjusting screw 402 can be placed on the card holder 404 for easy carrying, while also preventing the adjusting screw 402 from affecting storage.
