Description

Technical Field

[0001] This application relates to the field of total station protection technology, and in particular to a canopy safety protection device. Background Technology

[0002] As a high-precision surveying device, total stations often require long-term continuous observation in the field. Therefore, they need to be equipped with appropriate protective facilities to avoid damage from natural factors such as rain, sunlight, and sandstorms. Currently, the common practice is to build rain shelters for total stations to provide basic rain and sun protection.

[0003] However, existing canopy structures are mostly simple constructions, usually fixed only by simple binding methods such as wire. However, binding with wire is not only not very sturdy, but also easily affected by wind, causing the canopy to sway, deform or even collapse, affecting the safety of total station operation. At the same time, it lacks lightning protection structure, posing a significant safety hazard in thunderstorms, thus affecting the use of total station. Summary of the Invention

[0004] To address the issues of poor robustness and lack of lightning protection structure in the rain shelter safety protection device of total stations, which affect the use of total stations, this application provides a rain shelter safety protection device.

[0005] This application provides a safety protection device for a rain shelter, which adopts the following technical solution: A canopy safety protection device includes an adjustable support rod, the top of which is connected to a canopy panel. A cross-shaped reinforcing plate is installed on the top of the canopy panel, and a diagonal cable for tightening the canopy panel is installed on the cross-shaped reinforcing plate. A retraction and release structure for retracting the diagonal cable is installed on the support rod. The end of the diagonal cable away from the cross-shaped reinforcing plate is wrapped around the retraction and release structure. A lightning arrester is installed on the top of the canopy panel, and the lightning arrester is located on the cross-shaped reinforcing plate.

[0006] By adopting the above technical solutions, the cross-shaped reinforcement plate at the top of the canopy panel can evenly distribute the force of the canopy panel to the entire panel, avoiding excessive local stress that could lead to deformation and cracking of the canopy panel. One end of the diagonal rope is fixed to the cross-shaped reinforcement plate, and the other end is tightened through the retractable structure on the support rod, which is equivalent to adding "diagonal tension support" to the canopy panel. This design breaks the single structure of traditional canopies that only rely on the "vertical support" of the support rod, forming a three-dimensional force system of "vertical support + diagonal tension", which greatly improves the ability to resist strong winds. At the same time, the retractable structure can adjust the tension of the rope, which can be flexibly adjusted according to the wind force and load-bearing requirements of the canopy's usage environment, further optimizing the structural stability. The lightning arrester is integrated into the cross-shaped reinforcement plate, which can directly introduce lightning above the canopy into the grounding system, avoiding the high-voltage current generated after lightning strikes the canopy from damaging surrounding electrical appliances and equipment, or causing fire or electric shock risks, thereby achieving better wind and lightning protection effects.

[0007] Preferably, the retractable structure includes a connecting plate, a connecting column, and a rotating disk. One end of the connecting plate is connected to the surface of the support rod, the surface of the connecting column is rotatably connected to the connecting plate, one end of the connecting column is fixedly connected to the rotating disk, the rotating disk is provided with a handle for retractable rotation, the side of the rotating disk near the connecting plate is rotatably connected to the connecting plate, and the inclined rope is wound around the surface of the connecting column.

[0008] By adopting the above technical solution, the handle on the rotating disk is equivalent to a "lever arm extension rod". Users do not need to use additional tools. They can drive the rotating disk and the connecting column to rotate synchronously by simply turning the handle. When the connecting column rotates, the diagonal rope wrapped around its surface will "wind up" or "release" in the direction of rotation. At the same time, the diagonal rope is directly wrapped around the surface of the connecting column, and the connecting column is fixed to the support rod through the connecting plate. The axis is stable when rotating, which can ensure that the rope is always evenly wound along the axis of the connecting column. This avoids the problem of jamming or knotting caused by the rope being tangled in the traditional winding and releasing structure, and improves the adjustment efficiency.

[0009] Preferably, the rotating disk is further provided with fixing bolts for fixing the rotating disk, and the fixing bolts are threadedly connected to the connecting plate.

[0010] By adopting the above technical solution, the fixing bolt is rigidly connected to the connecting plate through threads. After the tension of the inclined rope is adjusted, the fixing bolt is tightened, and its end can tightly press against the surface of the rotating disk to form a physical lock, directly restricting the rotation of the rotating disk. Even if the inclined rope is subjected to strong tension, the rotating disk cannot rotate, ensuring the long-term stability of the tension of the inclined rope and avoiding the risk of the canopy shaking, deformation or even collapse caused by the slack of the inclined rope.

[0011] Preferably, the support rod includes a main rod and a secondary rod. The main rod is sleeved on the surface of the secondary rod, and the top end of the secondary rod is connected to the canopy panel. Both the secondary rod and the main rod have locking holes. A locking post is provided in the locking hole on the main rod. A through hole is provided on the surface of the locking post, and a positioning post is provided in the through hole on the locking post.

[0012] By adopting the above technical solution, since the size of the safety protection device of the canopy is different, the usage scenarios have clear differences in height requirements. By using the locking holes and locking posts at different positions between the main rod and the auxiliary rod, the length of the support rod is adjusted. There is no need to replace the support rod, so it can be adapted to different installation positions and usage requirements. It is simple to operate and easy to adjust.

[0013] Preferably, the number of locking holes on the secondary rod is several, and the locking holes are evenly distributed on the surface of the secondary rod.

[0014] By adopting the above technical solution, slight differences may exist in the flatness of the ground and the height of the reserved installation points on the wall during actual installation. The evenly distributed holes can compensate for these minor errors by "fine-tuning the gears". There is no need to perform additional leveling or grinding on the installation environment, which greatly reduces the complexity of construction and improves installation efficiency.

[0015] Preferably, the bottom end of the main rod is provided with a mounting hole for fixing the support rod to the ground, and the mounting hole is used in conjunction with the anchor bolts on the ground.

[0016] By adopting the above technical solution, the main pole is installed by using mounting holes on the main pole and anchor bolts to fix the main pole, thereby fixing the canopy to the equipment on the ground, covering the equipment, stabilizing the support pole, and preventing the support pole from shaking.

[0017] Preferably, the top of the canopy panel is provided with an anti-slip layer, the anti-slip layer is made of plastic, and the cross-shaped reinforcing plate is located between the anti-slip layers.

[0018] By adopting the above technical solution and setting an anti-slip layer, on the one hand, the anti-slip layer itself is not easy to fall off the surface of the canopy panel, and on the other hand, the position of the cross reinforcement plate is more stable, forming an integrated structure in which the anti-slip layer, the cross reinforcement plate, and the canopy panel are tightly combined, further improving the canopy panel's resistance to deformation and impact.

[0019] Preferably, the surge protector can be a lightning rod or a lightning arrester, and the surge protector and the cross-shaped reinforcing plate are detachably connected.

[0020] By adopting the above technical solutions, scenario adaptability and compliance economy are achieved through the "two-option surge protector" approach, installation and maintenance flexibility and low cost are achieved through the "detachable connection" approach, and structural reuse and installation stability are achieved through the "reinforcement plate" approach. Ultimately, an optimized design is formed that is "reliable in lightning protection, easy to construct, worry-free in maintenance, and cost-controllable".

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, with three-dimensional reinforcement and collective protection as its core, not only solves the core pain point of the transmission canopy's weak wind and load resistance, but also improves adaptability through design adjustments, while taking into account safety requirements such as lightning protection and anti-fall-off, thus balancing safety, practicality and economy, thereby improving the canopy's protective effect on the total station and making the canopy more robust. 2. By setting up a support rod formed by a main rod and a secondary rod, the height of the support rod can be adjusted by adjusting the positional relationship between the main rod and the secondary rod, thereby adjusting the height of the canopy and making the canopy adaptable to different total stations. 3. By offering a choice between two surge protectors, we achieve scenario adaptability and compliance with economics. By providing detachable connections, we achieve flexibility and low cost in installation and maintenance. By leveraging cross-shaped reinforcement plates, we achieve structural reuse and installation stability. Ultimately, we have created an optimized design that is reliable in lightning protection, easy to construct, worry-free in maintenance, and cost-controllable. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0025] This application discloses a canopy safety protection device.

[0026] Reference Figure 1 and Figure 2 A canopy safety protection device includes a support rod 1, which is telescopically adjustable to adjust its length according to the height of the device. The bottom end of the support rod 1 has a mounting hole 7 for fixing the support rod 1 to the ground. A canopy panel 2, which is square in shape, is fixedly connected to the top of the support rod 1, providing shielding and protection for the total station. A cross-shaped reinforcing plate 3 is fixedly connected to the top of the canopy panel 2, with its four ends located at the four corners of the canopy panel 2. The cross-shaped reinforcing plate 3 is integrated with the canopy panel 2. The diagonals of plate 2 coincide, allowing the cross-shaped reinforcing plate 3 to reinforce the canopy plate 2. Four diagonal ropes 4 are fixedly connected to the cross-shaped reinforcing plate 3 for tightening the canopy plate 2, and each diagonal rope 4 is attached to the top of the cross-shaped reinforcing plate 3. A retraction structure 5 for retracting the diagonal ropes 4 is connected to the support rod 1. The end of the diagonal rope 4 away from the cross-shaped reinforcing plate 3 is wrapped around the retraction structure 5, allowing the diagonal rope 4 to adjust its tension through the retraction structure 5. A lightning arrester 6 is installed on the top of the canopy plate 2, located on the cross-shaped reinforcing plate 3.

[0027] Through the above scheme, by fixing the support rod 1 to the ground, and then reinforcing the top of the canopy panel 2 with the cross reinforcement plate 3, the inclined rope 4 and the retraction structure 5 work together to pull down the canopy panel 2, making the canopy panel 2 stable and avoiding the influence of wind, thus improving the wind resistance of the canopy safety protection device. At the same time, the lightning arrester 6 is installed to enable the canopy safety protection device to protect against lightning, thereby improving the lightning protection effect of the device.

[0028] An anti-slip layer 8 is fixedly connected to the top of the canopy panel 2. A cross-shaped reinforcing plate 3 is snapped between the anti-slip layers 8, so that the anti-slip layer 8 limits the cross-shaped reinforcing plate 3 and reduces the sliding of the cross-shaped reinforcing plate 3. By setting the anti-slip layer 8, on the one hand, the anti-slip layer 8 itself is not easy to fall off the surface of the canopy panel 2, and on the other hand, the position of the cross-shaped reinforcing plate 3 is more stable, forming an integrated structure in which the anti-slip layer 8, the cross-shaped reinforcing plate 3, and the canopy panel 2 are tightly connected, further improving the deformation resistance and impact resistance of the canopy panel 2.

[0029] refer to Figure 2 The surge protector 6 can be a lightning rod or a lightning arrester, and the connection between the surge protector 6 and the cross-shaped reinforcing plate 3 is a detachable connection, which allows the surge protector 6 to be replaced, thus avoiding damage to the surge protector 6 and affecting the lightning protection effect of the device.

[0030] refer to Figure 3The retractable structure 5 includes two connecting plates 51. The ends of the two connecting plates 51 near the support rod 1 are fixedly connected to the support rod 1, so that the support rod 1 provides support for the connecting rod. A connecting post 52 is rotatably connected between the two connecting plates 51, so that the connecting post 52 can rotate on the connecting plates 51. The end of the inclined rope 4 away from the cross reinforcement plate 3 is wrapped around the connecting post 52. A rotating disk 53 is fixedly connected to one end of the connecting post 52. The side of the rotating disk 53 near the connecting plate 51 is rotatably connected to the connecting plate 51. A handle 55 is detachably connected to the rotating disk 53. The rotating disk 53 is rotated by the handle 55, which in turn drives the connecting post 52 to rotate, thereby tightening or loosening the inclined rope 4.

[0031] With the above solution, by rotating the rotating disk 53 on the connecting plate 51 by rotating the handle 55, the rotating disk 53 drives the connecting column 52 to rotate, so that the connecting column 52 can tighten or loosen the inclined rope 4, which can make it more convenient to adjust the tension of the inclined rope 4. At the same time, the inclined rope 4 is directly wrapped around the surface of the connecting column 52, and the connecting column 52 is fixed to the support rod 1 through the connecting plate 51. The axis is stable when rotating, which can ensure that the rope is always evenly wrapped along the axis of the connecting column 52, avoiding the problem of jamming or knotting caused by the rope being tangled in the traditional winding and releasing structure 5, and improving the adjustment efficiency.

[0032] The rotating disk 53 is threaded with fixing bolts 54 for fixing the rotating disk 53. The fixing bolts 54 are threadedly connected to the connecting plate 51 to limit and fix the rotating disk 53. By making the fixing bolts 54 rigidly connected to the connecting plate 51, after the tension of the inclined rope 4 is adjusted, the fixing bolts 54 fix the rotating disk 53, limiting the rotation of the rotating disk 53, ensuring the long-term stability of the tension of the inclined rope 4, and avoiding the risk of the canopy shaking, deforming or collapsing due to the loosening of the inclined rope 4.

[0033] refer to Figure 4 and Figure 5 The support rod 1 includes a main rod 11 and a secondary rod 12. The top end of the main rod 11 is slidably connected to the secondary rod 12, and the bottom end of the secondary rod 12 passes through the top end of the main rod 11 and is located inside the main rod 11. The main rod 11 and the secondary rod 12 are provided with locking holes 13, and there are several locking holes 13 on the secondary rod 12. The locking holes 13 are evenly distributed on the surface of the secondary rod 12. Locking pins 14 are inserted into the locking holes 13 corresponding to the main rod 11, so that the locking pins 14 limit the distance between the secondary rod 12 and the main rod 11. The locking pins 14 are provided with through holes 15, and positioning pins 16 are inserted into the through holes 15, so that the positioning pins 16 limit the locking pins 14 and prevent the locking pins 14 from falling off the secondary rod 12 and the main rod 11.

[0034] With the above solution, since the size of the safety protection device of the canopy is different, the usage scenarios have clear differences in height requirements. By using the locking holes 13 and locking posts 14 at different positions between the main rod 11 and the auxiliary rod 12, the length of the support rod 1 is adjusted. There is no need to replace the support rod 1, so it can be adapted to different installation positions and usage requirements. Its operation is simple and easy to adjust.

[0035] The implementation principle of this application embodiment is as follows: In implementation, the mounting hole 7 at the bottom of the main rod 11 on the support rod 1 is fixed with the anchor bolts on the ground to fix the support rod 1. Then, the height of the secondary rod 12 on the support rod 1 is adjusted according to the requirements. After adjustment, the locking hole 13 on the secondary rod 12 corresponds to the locking hole 13 on the main rod 11, so that the locking post 14 is inserted into the locking hole 13 to position the main rod 11 and the secondary rod 12. Then, the positioning post 16 is inserted into the through hole 15 on the locking post 14 to fix the locking post 14 and prevent the locking post 14 from falling off the main rod 11. After adjustment, the user can rotate the rotating disk 5 on the connecting plate 51 by the handle 55. 3. The rotating disc 53 drives the inclined rope 4 to tighten, pulling the canopy panel 2 downwards and stabilizing it horizontally. After tightening, the fixing bolt 54 is rotated to fix it to the connecting plate 51, thereby fixing the rotating disc 53 and stabilizing the inclined rope 4, thus reinforcing the canopy. The cooperation between the inclined rope 4 and the cross reinforcement plate 3 strengthens the safety protection device of the canopy, improving its wind resistance and tensile strength. At the same time, in the event of a thunderstorm, if the lightning arrester 6 is struck, the lightning will conduct the shock through the grounding of the lightning arrester 6, preventing damage to the total station under the canopy safety protection device and ensuring a stable working environment.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
