Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy safety protection equipment, specifically a safety protection device for water conservancy project management. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They facilitate the control of water flow, prevent floods, and regulate and distribute water to meet the water needs of people's lives and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways. Especially during the construction of dams and dikes in rivers, lakes, or reservoirs, safety railings need to be built near the banks to protect the workers and ensure their safety.

[0003] Traditional safety protection devices for water conservancy project management are usually integrally welded, which are inconvenient to disassemble and cannot meet the actual needs of use. In response, an existing patent (publication number: CN218759232U) discloses a safety protection device for water conservancy projects. The components are assembled to form a whole protective fence. The device is easy to disassemble and transport, and has the advantages of convenient assembly and disassembly, reasonable structural layout, high practicality, and is worthy of widespread promotion.

[0004] To address the above problems, existing patents have provided solutions, but they still have the following shortcomings in use: 1. The width of a single protective device is fixed and cannot be adjusted, resulting in poor flexibility in use and a large width occupation during transportation; 2. The guardrail does not have a buffer function, and when the guardrail is impacted, it is easy to cause serious damage to the impact body or the guardrail, reducing the overall safety factor; Therefore, a safety protection device for water conservancy project management is proposed.

[0005] The purpose of this utility model is to provide a safety protection device for water conservancy project management to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for water conservancy project management, comprising:

[0007] The side frames consist of two sets, arranged in an L-shape and symmetrically.

[0008] A telescopic protective assembly is installed between two side frames, and two L-shaped lugs are fixedly connected to both sides of the telescopic protective assembly; the telescopic protective assembly is used to adjust the protective distance between the two L-shaped lugs and to provide shielding protection in water conservancy project management.

[0009] The buffer support assembly consists of four sets, each fixed in pairs to one side of two adjacent side frames. Support sleeves are fixedly connected to the adjacent sides of the two opposing buffer support assemblies. Rectangular locking holes are provided on the bottom inner wall of the support sleeves, and the L-shaped lugs are movably locked within the corresponding rectangular locking holes. The buffer support assembly is used to guide the telescopic protective assembly laterally and buffer and dissipate force when it is impacted. The L-shaped lugs and the movable locking holes facilitate easy assembly and disassembly of the telescopic protective assembly and side frames through simple insertion and removal.

[0010] Preferably, the telescopic protective assembly includes an outer U-shaped frame and an inner U-shaped frame. The outer U-shaped frame is slidably fitted onto the inner U-shaped frame. Three guard tubes are fixedly connected to the left inner wall of the outer U-shaped frame. A guard bar, which is fixedly connected to the right inner wall of the inner U-shaped frame, is slidably fitted inside the guard tubes. A horizontal screw is rotatably embedded on the left inner wall of the outer U-shaped frame. The middle guard bar is threaded onto the horizontal screw. The left end of the horizontal screw extends to the left side of the outer U-shaped frame and is fixedly connected to a rocker plate. Both the outer U-shaped frame and the inner U-shaped frame are fixedly installed with corresponding L-shaped lugs.

[0011] Preferably, the buffer support assembly includes a fixed shell fixedly connected to the side of the corresponding side frame near the outer U-shaped frame. The two adjacent sides of the two fixed shells are both set as openings. Two guide posts are fixedly connected between the front and rear inner walls of the fixed shell. The same guide seat is slidably sleeved on the outer side of the two guide posts located in the same fixed shell. The guide seat is welded and fixed to the outer side of the corresponding support sleeve.

[0012] Preferably, the bottom of the side frame has two mounting holes, and two casters are rotatably mounted on the bottom of the side frame.

[0013] Preferably, a rectangular sleeve is fixedly connected to the left side of the side frame located on the left side.

[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] like Figures 1 to 4 As shown in this embodiment, a safety protection device for water conservancy project management includes:

[0027] Side frame 1, which consists of two sets, is L-shaped and symmetrically arranged. There are two mounting holes at the bottom of side frame 1. Two casters 101 are rotatably mounted at the bottom of side frame 1. The mounting holes are for personnel to install and fix side frame 1 using external bolts or expansion bolts. The casters 101 are for easy movement of side frame 1.

[0028] The telescopic protective assembly is installed between the two side frames 1. Two L-shaped hanging ears 206 are fixedly connected to both sides of the telescopic protective assembly. The telescopic protective assembly is used to adjust the protective distance between the two L-shaped hanging ears 206 and to provide shielding protection in water conservancy project management.

[0029] The buffer support assembly consists of four sets, each fixed in pairs to one side of the two adjacent side frames 1. Support sleeves 304 are fixedly connected to the adjacent sides of the two opposing buffer support assemblies. Rectangular locking holes 305 are provided on the bottom inner wall of the support sleeve 304, and L-shaped hooks 206 are movably fitted into the corresponding rectangular locking holes 305. The buffer support assembly is used to guide the telescopic protective assembly laterally and buffer and dissipate force when it is impacted. The movable locking method of the L-shaped hooks 206 and the rectangular locking holes 305 facilitates the assembly and disassembly of the telescopic protective assembly and the side frames through simple insertion and removal.

[0030] The top of the upper L-shaped lug 206 is in contact with a knob bolt 306. The top of the upper support sleeve 304 is provided with a first threaded hole that is threaded to the corresponding knob bolt 306. The knob bolt 306 is used to lock and restrict the corresponding L-shaped lug 206, preventing the risk of it accidentally coming out of the rectangular locking hole 305 during use and improving the stability of use.

[0031] It should be noted that the rotating installation of the movable wheel 101 and the side frame 1 is conventionally achieved by rotating the wheel with bearings. Specifically, a groove can be cut at the bottom of the side frame 1, and a rotating shaft can be inserted and installed inside the movable wheel 101. Bearings for support can be installed on the outer sides of the front and rear ends of the rotating shaft, and the bearings can be fixed to the inner wall of the groove. This simple installation method of the movable wheel 101 is a conventional technology and will not be described in detail here.

[0032] The distance between the top inner wall of the support sleeve 304 and the top of the L-shaped lug 206 is greater than the distance between the top and bottom of the L-shaped lug 206. This is so that when the L-shaped lug 206 moves upward, the bottom of the L-shaped lug 206 can move into the support sleeve 304.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, the telescopic protective assembly includes an outer U-shaped frame 2 and an inner U-shaped frame 201. The outer U-shaped frame 2 is slidably fitted onto the inner U-shaped frame 201. Both ends of the right side of the outer U-shaped frame 2 have transverse guide grooves that slide in contact with the outer side of the inner U-shaped frame 201. A limiting hole is formed on the bottom inner wall of the lower transverse guide groove. A limiting bracket is fixedly connected to the bottom of the inner U-shaped frame 201 and slidably connected to the limiting hole, serving to guide the lateral sliding of the inner U-shaped frame 201 and prevent it from detaching. Three guard tubes 202 are fixedly connected to the left inner wall of the outer U-shaped frame 2. A guard bar 203, fixedly connected to the right inner wall of the inner U-shaped frame 201, is slidably fitted inside the guard tubes 202. A horizontal screw 204 is rotatably embedded on the left inner wall of the outer U-shaped frame 2. A circular through hole is opened on the left inner wall of the outer U-shaped frame 2, and a support bearing is fixedly sleeved in the circular through hole. The inner side of the inner ring of the support bearing is fixedly connected to the outer side of the horizontal screw 204, which achieves the effect of rotating the horizontal screw 204. The middle guard bar 203 is threaded on the horizontal screw 204. The left end of the middle guard bar 203 is opened with a second threaded hole that is threadedly connected to the horizontal screw 204. The left end of the horizontal screw 204 extends to the left side of the outer U-shaped frame 2 and is fixedly connected to the rocker plate 205. Both the outer U-shaped frame 2 and the inner U-shaped frame 201 are fixedly installed with the corresponding L-shaped lugs 206.

[0034] In this implementation scheme, the outer U-shaped frame 2, inner U-shaped frame 201, barrier tube 202, barrier bar 203, horizontal screw 204, and rocker 205 work together. By rotating the rocker 205, the horizontal screw 204 is driven to rotate. The rotation of the horizontal screw 204 causes the middle barrier bar 203 to slide laterally within the barrier tube 202. The middle barrier bar 203 causes the inner U-shaped frame 201 to slide laterally within the outer U-shaped frame 2. The inner U-shaped frame 201 causes the other two barrier bars 203 to slide laterally within their respective barrier tubes 202. This changes the width of the barrier formed by the outer U-shaped frame 2 and the inner U-shaped frame 201, allowing for convenient and flexible adjustment of the protective distance between the two side frames 1. This enables convenient and flexible adjustment of the barrier width of a single safety protection device, improving applicability. In addition, the adjustable barrier width also allows for subsequent reduction of the occupied volume by narrowing the width, providing convenience for transportation.

[0035] It should be noted that the horizontal screw 204 is a high-strength stainless steel screw with a high wear-resistant load-bearing specification of 0.2-0.35mm for the outer thread clearance. The guardrail 203 is made of stainless steel, which utilizes the advantages of high hardness, rust resistance and wear resistance to ensure long-term connection stability.

[0036] Furthermore, such as Figure 3 and Figure 4 As shown, the buffer support assembly includes a fixed shell 3 fixedly connected to the side of the corresponding side frame 1 near the outer U-shaped frame 2. The two fixed shells 3 facing each other on the same side are both set as openings. Two guide posts 301 are fixedly connected between the front and rear inner walls of the fixed shell 3. The same guide seat 302 is slidably sleeved on the outer side of the two guide posts 301 located in the same fixed shell 3. The front side of the guide seat 302 has two guide holes that are slidably sleeved on the outer side of the corresponding guide posts 301, which play a role in guiding the guide seat 302 to slide laterally. The guide seat 302 is welded and fixed to the outer side of the corresponding support sleeve 304. Two springs 303 are fixedly connected between the front and rear sides of the guide seat 302 and the inner wall of the fixed shell 3. The springs 303 are movably sleeved on the corresponding guide posts 301.

[0037] In this embodiment, the fixed shell 3, guide seat 302, guide column 301, and spring 303 work together to ensure that when the telescopic protective assembly formed by the outer U-shaped frame 2, inner U-shaped frame 201, barrier tube 202, and barrier bar 203 is accidentally impacted, it will displace backward upon impact, causing the four L-shaped lugs 206 to displace backward as well. The four L-shaped lugs 206 will then displace the corresponding support sleeves 304 backward, causing the corresponding guide seats 302 to slide backward on the two guide columns 301. This will compress or stretch the multiple springs 303, using the elasticity of the springs 303 to buffer and dissipate the impact force. After the force is dissipated, the corresponding guide seats 302 will rebound and reset, thereby driving the telescopic protective assembly to move back and reset to continue its protective work. This achieves the effect of guiding and buffering the telescopic protective assembly backward when it is impacted, reducing the risk of impact damage by using elastic force dissipation.

[0038] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, a rectangular sleeve 102 is fixedly connected to the left side of the side frame 1 located on the left side. The top of the rectangular sleeve 102 is provided with a threaded through hole, and a T-shaped screw 103 is screwed into the threaded through hole. A rectangular card seat 104 that matches the rectangular sleeve 102 is fixedly connected to the right side of the side frame 1 located on the right side. The top of the rectangular card seat 104 is provided with a circular slot that matches the T-shaped screw 103.

[0039] In this implementation scheme, by using the rectangular sleeve 102, T-shaped screw 103, rectangular seat 104, and circular slot, when the width to be protected at the construction site of a water conservancy project is large and multiple devices need to be connected together, the rectangular seat 104 of one device is inserted into the rectangular sleeve 102 of another device, and then the T-shaped screw 103 is rotated forward to move downward and lock into the circular slot. This allows the assembly and connection of two adjacent devices, so that multiple devices can be connected together to form a whole for better barrier work.

[0040] The usage method of this embodiment is as follows: When using the safety protection device for water conservancy project management, place the device in the designated position, rotate the rocker 205 in the forward direction to drive the horizontal screw 204 to rotate, the rotation of the horizontal screw 204 causes the middle guardrail 203 to slide to the right inside the guardrail tube 202, the middle guardrail 203 causes the inner U-shaped frame 201 to slide laterally inside the outer U-shaped frame 2, the inner U-shaped frame 201 causes the other two guardrails 203 to slide laterally inside their respective guardrail tubes 202, the inner U-shaped frame 201 passes sequentially through the L-shaped lug 206 on the right side, the support sleeve 304, and so on. The guide seat 302, guide column 301 and fixed shell 3 drive the right side frame 1 to move to the right. The right side frame 1 drives the corresponding moving wheel 101 to move to the right. After the adjustment is appropriate, stop turning the rocker 205. At this time, the guard width formed by the outer U-shaped frame 2 and the inner U-shaped frame 201 changes, so as to achieve the effect of convenient and flexible adjustment of the protective distance between the two side frames 1. This achieves the effect of convenient and flexible adjustment of the guard width of a single safety protection device, improves applicability and flexibility of use, and the number of safety protection devices can be reduced by increasing the width adjustment.

[0041] Then, personnel install and fix the side frame 1 by installing through holes and using external bolts or expansion bolts. When the telescopic protective assembly formed by the outer U-shaped frame 2, inner U-shaped frame 201, guard tube 202 and guard bar 203 is accidentally impacted, it is impacted and moves backward, causing the four L-shaped lugs 206 to move backward. The four L-shaped lugs 206 respectively drive the corresponding support sleeves 304 to move backward. The support sleeves 304 drive the corresponding guide seats 302 to slide backward on the two guide columns 301, and compress or stretch the multiple springs 303. The elastic force of the springs 303 is used to buffer and unload the impact force. After unloading the force, the corresponding guide seats 302 are driven to spring back and reset, thereby driving the telescopic protective assembly to move back and reset to continue the protective work. This achieves the effect of guiding and buffering the telescopic protective assembly in the front and rear when it is impacted. By using elastic unloading, the risk of serious damage to the assembly and the impact body is reduced, and the safety factor is improved.

[0042] When a large area needs protection at a water conservancy project construction site, requiring multiple devices to be interconnected, the rectangular holder 104 of one device is inserted into the rectangular sleeve 102 of another device. Then, the T-shaped screw 103 is rotated clockwise to move it downwards and engage it in the circular slot. This allows for the assembly and connection of adjacent devices, enabling multiple devices to be interconnected for better barrier protection. For subsequent disassembly, after releasing the fixing of the opposite side frame 1, the T-shaped screw 103 is rotated counterclockwise to remove it from the corresponding circular slot, separating the multiple devices. Then, the knob bolt 306 is rotated counterclockwise to release it from the corresponding L-shaped... With the hanging ear 206 blocking the view, the outer U-shaped frame 2 and the inner U-shaped frame 201 can be pulled up to move the L-shaped hanging ear 206 upward from the corresponding rectangular slot 305. This allows the side frame 1 to be moved to the side, so that the support sleeve 304 separates from the corresponding L-shaped hanging ear 206, thus separating the two side frames 1 from the telescopic protective component. Then, the rocker 205 is rotated in the opposite direction, which is completely opposite to the forward rotation of the rocker 205. At this time, the inner U-shaped frame 201 slides to the left inside the outer U-shaped frame 2, shrinking the overall width formed by the two. This achieves the effect of being detachable and having a shorter width when not in use, reducing the volume occupied by reducing the width and providing convenience for transportation.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
