Description

Technical Field

[0001] This utility model relates to the field of water conservancy safety protection, and in particular to an adjustable water conservancy project safety protection device. Background Technology

[0002] During the construction and operation of water conservancy projects, there are safety risks such as falls and accidental intrusions in areas such as slopes, foundation pits, and canal banks. Safety protection devices are key facilities to ensure the safety of construction personnel and the surrounding environment.

[0003] Traditional protective devices only use fixed railings or protective nets and lack active anti-climbing design. People can easily use the railings to climb over the protective facilities and enter dangerous areas, especially at night or during periods of weak supervision, which poses a significant safety hazard. Utility Model Content

[0004] The present invention aims to provide an adjustable safety protection device for water conservancy projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable safety protection device for hydraulic engineering includes a column, a horizontal bar, and an extension rod. The horizontal bar and the extension rod are rotatably connected to a rotary joint. The rotary joint is connected to a mounting plate, which is detachably connected to the column. The horizontal bar has a storage groove, and the extension rod is slidably connected to the storage groove. The extension rod also has a sliding groove, and a buckle is slidably connected to the side wall of the sliding groove. A spring is connected to the buckle, and the other end of the spring is connected to the side wall of the sliding groove. The horizontal bar has a locking hole, and the buckle and the locking hole cooperate with each other. A blocking mechanism is connected to the side wall of the locking hole. The blocking mechanism includes a baffle, and a limiting groove is formed on the side wall of the locking hole. The baffle is slidably connected to the limiting groove. A second spring is connected to the baffle, and the other end of the second spring is connected to the side wall of the limiting groove. Two sets of blocking mechanisms are provided, and the two sets cooperate with each other.

[0007] Preferably, the baffle is connected to a rubber pad, the baffle has a chamfer, and the buckle cooperates with the chamfer.

[0008] Preferably, the buckle is connected to a T-shaped block, and the side wall of the slide groove is provided with a T-shaped groove, and the T-shaped block is slidably connected to the T-shaped groove.

[0009] Preferably, the column is connected to a reflective strip.

[0010] Preferably, the column is connected to a positioning plate, and the positioning plate has positioning holes.

[0011] Preferably, the positioning plate is connected to a support plate, and the other end of the support plate is connected to the column.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0013] (1) This solution uses a rotary joint to allow the horizontal bar and extension bar to rotate freely around the column, forming an anti-climbing barrier. When a person attempts to climb, the horizontal bar and extension bar will rotate with the external force, destroying the climber's fulcrum and preventing them from climbing stably with the horizontal bar. This prevents climbing behavior from the source, solves the problem that traditional fixed horizontal bars are easily used for climbing, and significantly improves the safety protection level of the protective device. By setting a sliding groove, spring one, buckle and locking hole, the protective width can be accurately adapted. When the extension bar slides along the storage groove, the buckle automatically engages with the corresponding locking hole under the action of spring one, quickly fixing the adjustable length. This solves the problem that the fixed width of traditional protective devices cannot adapt to the span of different construction areas, and can flexibly cope with different protection scenarios. By setting a shielding mechanism, two corresponding baffles fit together under the elastic force of spring two, forming a sealed cover for the locking hole. This can effectively prevent debris or rainwater from entering the interior of the horizontal bar through the locking hole, avoiding the impact on the service life of the internal structure due to debris accumulation or water corrosion, and ensuring the long-term stable operation of the adjustable structure.

[0014] (2) A chamfer is provided to guide the engagement of the buckle. When the extension rod slides for adjustment, the buckle contacts the chamfer of the baffle and naturally compresses the baffle, thus compressing the spring. This allows the buckle to engage smoothly with the locking hole without manual operation, simplifying the adjustment process and improving ease of operation. Simultaneously, by placing a rubber pad on the baffle, the elastic sealing properties of rubber ensure tight contact between the two baffles, further enhancing the sealing effect. This effectively prevents moisture from seeping into the locking hole through the gaps between the baffles, avoiding rust and failure of the buckle and spring inside the locking hole due to water ingress, extending the service life of the components, and ensuring the reliability of the adjustment structure.

[0015] (3) By setting T-blocks and T-slots, the buckle is guided and limited. When the buckle slides along the slide, the T-block moves synchronously along the T-slot, preventing the buckle from misaligning or failing due to force deviation, ensuring that the buckle is always accurately aligned with the buckle hole, extending the service life of the adjustment structure, and reducing the maintenance needs caused by component misalignment.

[0016] (4) By setting reflective strips, the warning effect in harsh environments is enhanced. The reflective strips produce obvious reflections under light, and in low visibility environments such as at night, heavy rain or fog, they can effectively remind people to pay attention to dangerous areas. Combined with the rotating anti-climb structure, they form a dual guarantee of physical protection and visual warning, which solves the shortcomings of the single warning function of traditional protective devices and improves the overall safety protection effect.

[0017] (5) By setting up positioning plates and support plates, the overall anti-overturning capacity of the device is improved. The positioning plates are fixed to the ground with anchor bolts through positioning holes, and the support plates are diagonally connected to the positioning plates and columns, distributing the force on the columns and enhancing the installation stability on soft or uneven ground. Compared with traditional simple fixing methods, the detachable column installation facilitates transportation and terrain adaptation, ensuring that the device stands firmly in complex environments.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0023] like Figure 1-3The adjustable safety protection device for hydraulic engineering shown includes two columns 1, horizontal bars 7, and extension bars 5. The columns 1 are made of high-strength steel with anti-corrosion treatment to withstand humid outdoor environments. The horizontal bars 7 and extension bars 5 are rotatably connected to rotary joints 11, each connected to a mounting plate 10. The mounting plates 10 are detachably connected to their respective columns 1, allowing the horizontal bars 7 and extension bars 5 to rotate freely around the columns 1. When a person attempts to climb, the horizontal bars 7 and extension bars 5 rotate under external force, disrupting the climber's support points and preventing them from using the horizontal bars 7 for stable climbing, thus fundamentally preventing the climbing attempt. Compared to traditional fixed horizontal bars 7, the anti-climbing effect is significantly improved. Multiple sets of horizontal bars 7 and extension bars 5 form multi-layered protection, further enhancing the anti-climbing capability. The mounting plate 10 and the column 1 are detachable via bolts, facilitating transportation, installation, and subsequent maintenance and replacement. Multiple sets of crossbars 7 and extension rods 5 are evenly distributed along the height of the column 1, forming a multi-layered protective barrier. The crossbar 7 has a storage groove 17. The outer wall of the extension rod 5 is tightly fitted to the inner wall of the storage groove 17 and can slide freely. The overall width can be adjusted by changing the length of the extension rod 5 extending into the storage groove 17. Each end of the extension rod 5 has a sliding groove 12. The side walls of the two sliding grooves 12 are slidably connected to buckles 6, and each buckle 6 is connected to a spring 13. The other ends of the two springs 13 are connected to the corresponding side walls of the sliding grooves 12. Under the elastic action of the springs 13, the buckles 6 always tend to pop outwards. Each end of the crossbar 7 has several locking holes 8. Each buckle 6 cooperates with a corresponding locking hole 8. When the extension rod 5 slides to the target position, the buckle 6 automatically pops out under the action of the spring 13 and locks into the corresponding locking hole 8, thus fixing the length. Each locking hole 8 has a blocking mechanism connected to its sidewall. The blocking mechanism includes a baffle 15. Each locking hole 8 has a limiting groove 14 at both ends of its sidewall. Each baffle 15 is slidably connected to its corresponding limiting groove 14. Each baffle 15 is connected to a spring 16, the other end of which is connected to the sidewall of its corresponding limiting groove 14. Each locking hole 8 has two sets of blocking mechanisms, which cooperate with each other. In its natural state, the two sets of baffles 15 are pressed together by the springs 16, forming a seal on the locking hole 8. When the buckle 6 is engaged, the buckle 6 contacts the chamfer and presses against the baffle 15, compressing the springs 16, causing the baffle 15 to automatically avoid the buckle 6.

[0024] like Figure 3As shown, each baffle 15 is connected to a rubber pad to seal the locking hole 8, preventing rainwater and debris from entering the crossbar 7. Each baffle 15 has a chamfer on its inner wall, and the buckle 6 cooperates with the chamfer. Each buckle 6 has a T-shaped block 19 connected to both ends, and each slide groove 12 has a T-shaped groove 18 at both ends of its side wall. Each T-shaped block 19 slides with its corresponding T-shaped groove 18. This provides guidance for the extension and retraction of the buckle 6, preventing the buckle 6 from shifting or jamming during sliding, and ensuring that the buckle 6 is precisely aligned with the locking hole 8.

[0025] like Figure 1 As shown, each column 1 is connected to a reflective strip 2. The reflective strip 2 is made of high-brightness reflective material, which can produce strong reflection under light, effectively alerting personnel to dangerous areas in low-visibility environments such as night, heavy rain, or dense fog. Each column 1 has a positioning plate 3 connected to both ends of its bottom, and each positioning plate 3 has several positioning holes 9. Each positioning plate 3 is connected to a support plate 4, and the other end of each support plate 4 is connected to the column 1. The positioning plates 3 are fixed to the ground via the positioning holes 9 and anchor bolts. The support plates 4 are diagonally connected to the positioning plates 3 and the columns 1, forming a triangular stable structure that distributes the force on the columns 1, enhances the device's resistance to overturning on soft or uneven ground, and ensures the device remains stable under the influence of external forces such as strong winds and collisions.

[0026] The specific implementation process is as follows:

[0027] In use, determine the spacing of the uprights 1 according to the width of the protected area. Fix the positioning plate 3 at the bottom of the uprights 1 to the ground with anchor bolts. Use a level to adjust the verticality of the uprights 1 to ensure that the two uprights 1 are parallel and at the same height. Pull the extension rod 5 along the storage groove 17 and adjust it to the required protective width. At this time, the buckle 6 will automatically engage with the corresponding hole 8 under the action of the spring 13. A "click" sound indicates that the fixing is complete. If the length needs to be shortened, press the buckle 6 to disengage it from the hole 8 and push the extension rod 5 to the target position. Then fix the mounting plate 10 to the preset height position of the uprights 1 with bolts. Install multiple sets of crossbars 7 and extension rods 5 according to the protection requirements.

[0028] When a person attempts to climb, the crossbar 7 and extension bar 5 will rotate under the action of external force, destroying the climber's fulcrum and making it impossible for them to climb stably with the help of the crossbar 7, thus fundamentally preventing the climbing behavior.
