Description

Technical Field

[0001] This utility model relates to the field of roof construction technology, specifically a safety device for the construction of a rooftop photovoltaic power station. Background Technology

[0002] Rooftop photovoltaic (PV) power stations require the installation of photovoltaic panels on the roof to generate electricity. However, some buildings and self-built houses may have sloping roofs. When installing PV panels on a slope, workers may need to stand or squat to perform the installation work. Because the roof is sloping, the body's center of gravity will shift along the slope. In addition, some buildings have strong winds, which can easily affect the worker's weight and make it easier for them to shift along the slope, affecting the stability of their center of gravity during installation work, which is quite inconvenient. Furthermore, when workers are installing PV systems, they usually use safety ropes tied around their waists for protection. Safety ropes are usually guaranteed to have a certain length so that workers can move within the length of the rope. However, if a worker slips and falls down the slope, the impact of the fall can easily increase the stress on the safety rope, increasing the burden on the safety rope and causing a safety accident. Utility Model Content

[0003] The purpose of this invention is to provide a safety device for the construction of rooftop photovoltaic power stations to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A construction safety device for a rooftop photovoltaic power station includes:

[0006] The system includes a ring-shaped guide rail, a support mechanism to reduce stress, a wearing mechanism for easy donning, and a fixing mechanism. Two support rods are fixedly connected to the outer wall of the ring-shaped guide rail, and a safety rope is also fixedly connected to the outer wall. The support mechanism is rotatably sleeved with the two support rods. The support mechanism includes two square tubes, each with a sleeve hole on one side. The inner sidewalls of the two sleeve holes are rotatably sleeved with the outer walls of the two support rods. A sliding rod is slidably sleeved at one end of each of the two square tubes, and a connecting rod is fixedly connected between the ends of the two sliding rods. A stop plate is rotatably sleeved on the outer wall of the connecting rod. Multiple insertion holes are provided on one side of each of the two sliding rods, and threaded holes are provided at one end of the outer wall of each of the two square tubes. The wearing mechanism is located inside the ring-shaped guide rail, and the fixing mechanism is located at one end of one of the support rods.

[0007] Furthermore, a counterweight plate is fixedly connected to the bottom surface of the abutment plate.

[0008] Furthermore, a lifting rod is fixedly connected between the other ends of the two square tubes.

[0009] Furthermore, the fixing mechanism includes:

[0010] The device includes an internal threaded ring, a screw-in rod, and multiple abutments. One side of the internal threaded ring is fixedly connected to one end of a support rod. One end of the support rod has a connecting hole, and the inner sidewall of the connecting hole has multiple sliding holes. The outer sidewall of the screw-in rod is screwed into the inner sidewall of the internal threaded ring. The multiple abutments correspond one-to-one with the multiple sliding holes, and the multiple abutments are slidably sleeved inside the corresponding sliding holes.

[0011] Furthermore, a magnet is fixedly connected to one end of the engagement rod, and the magnet is cylindrical with a diameter smaller than that of the engagement rod.

[0012] Furthermore, the wearable mechanism includes:

[0013] The device comprises a belt, multiple sleeves, and multiple sliders. One end of the belt is equipped with a buckle. Each of the multiple sleeves is rotatably connected to an internally threaded cylinder on one side. One end of the belt passes through the interior of the multiple sleeves and slides into the interior of the multiple sleeves. Each of the multiple sliders corresponds to one of the multiple internally threaded cylinders. Each of the multiple sliders is slidably engaged inside an annular guide rail, and each of the multiple sliders is fixedly connected to a screw on one side. The outer side wall of each of the multiple screws is screwed into the inner side wall of the corresponding internally threaded cylinder.

[0014] Furthermore, an arc-shaped rod is fixedly connected between each of the two adjacent sliders.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By fastening the waist belt around the waist and adjusting the distance between the waist belt and the circular guide rail by rotating multiple internal threaded cylinders to fit the user's waist circumference, the safety rope is then tied to the top of the roof slope. The sliding rod and the total length of the square tube are adjusted by sliding the sliding rod, and the sliding rod is fixed by screwing the bolt into the threaded hole and inserting it into the socket. The user can then place the counterweight plate at the lower part of the slope and rotate the screw rod to engage multiple abutments to fix the angle of the square tube. The counterweight plate supports the user's waist, and if the user slips or falls down the slope, the counterweight plate and square tube can provide a certain degree of support, reducing the impact force generated when the user falls, thereby reducing the stress on the safety rope and improving the safety of the user during work.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-6 In this embodiment of the utility model, a construction safety device for a rooftop photovoltaic power station includes:

[0026] The system comprises a ring-shaped guide rail 100, a support mechanism 200 for reducing stress, a wearing mechanism 300 for easy donning, and a fixing mechanism 400. Two support rods 110 are fixedly connected to the outer wall of the ring-shaped guide rail 100, and a safety rope 120 is fixedly connected to the outer wall of the ring-shaped guide rail 100. The support mechanism 200 is rotatably sleeved with the two support rods 110. The support mechanism 200 includes two square tubes 210, and each of the two square tubes 210 has a sleeve hole 211 on one side. The inner sidewalls of the two sleeve holes 211 are respectively connected to two… The outer wall of the support rod 110 is rotatably sleeved, and one end of each of the two square tubes 210 is slidably sleeved with a slide rod 220. A connecting rod 230 is fixedly connected between one end of each slide rod 220. A stop plate 231 is rotatably sleeved on the outer wall of the connecting rod 230. Multiple insertion holes 221 are opened on one side of each of the two slide rods 220, and threaded holes 212 are opened on one end of the outer wall of each of the two square tubes 210. The wearing mechanism 300 is located inside the annular guide rail 100, and the fixing mechanism 400 is located at one end of one support rod 110.

[0027] Specifically, during roof construction, if the roof is a flat slope, the user can use the wearing mechanism 300 to fix the ring guide rail 100 to their waist, then tie the safety rope 120 to the high point of the slope, and place the support plate 231 at the low point of the slope. The user can then perform the installation work. The user can slide the two sliding rods 220 as needed to adjust the total length of the sliding rods 220 and the adjacent square tube 210. The user can then use bolts screwed into the threaded holes 212 and through the adjacent insertion holes 221 to fix the position of the sliding rods 220. When the user is standing or squatting on the sloped roof, the support plate 231 located at the low point of the slope can support their waist, making it easier for the user to perform the installation work. In addition, if the user slips or falls to the low point of the slope, the support plate 231, being located at the low point of the slope, can provide a certain degree of support, reducing the impact force generated when the user falls, thereby reducing the stress on the safety rope 120 and improving the safety of the user during work.

[0028] Example 1

[0029] like Figure 1-2 As shown, in this embodiment, a counterweight plate 232 is fixedly connected to the bottom surface of the abutment plate 231, and a lifting rod 240 is fixedly connected between the other ends of the two square tubes 210.

[0030] In this embodiment, the counterweight plate 232 is a rubber plate with a certain weight and a large friction with the roof floor. The counterweight plate 232 can contact the ground due to its own weight, and when the user moves on the sloping roof, the counterweight plate 232 can be lifted off the roof floor by pressing the lifting rod 240.

[0031] like Figure 4-5 As shown, in this embodiment, the fixing mechanism 400 includes:

[0032] The device includes an internal threaded ring 410, a screw-in rod 420, and multiple abutment rods 430. One side of the internal threaded ring 410 is fixedly connected to one end of a support rod 110. One end of the support rod 110 has a connecting hole 111, and the inner wall of the connecting hole 111 has multiple sliding holes 112. The outer wall of the screw-in rod 420 is screwed into the inner wall of the internal threaded ring 410. The multiple abutment rods 430 correspond one-to-one with the multiple sliding holes 112. The multiple abutment rods 430 are all slidably sleeved inside the corresponding sliding holes 112. One end of the screw-in rod 420 is fixedly connected to a magnet 440, and the magnet 440 is cylindrical with a diameter smaller than that of the screw-in rod 420.

[0033] In practice, when the user operates the device, the rotating rod 420 can be rotated to disengage it from the multiple abutments 430. This allows the user to pre-adjust the angles of the two square tubes 210 by rotating them. Then, the rotating rod 420 can be rotated again to engage with the multiple abutments 430, causing them to contact the inner walls of the adjacent square tube 210 sleeve holes 211 to fix the angle of the square tube 210. This facilitates the user's operation. When the user rotates the rotating rod 420 to disengage from the multiple abutments 430, the multiple abutments 430 can be attracted by the magnet 440 and disengage from the inner walls of the adjacent sleeve holes 211, making it easier for the user to rotate the square tube 210 to adjust its angle.

[0034] Example 2

[0035] Based on Embodiment 1, the wearable mechanism 300 facilitates the user to fix the annular guide rail 100 to their waist.

[0036] like Figure 2-3 As shown, in this embodiment, the wearable mechanism 300 includes:

[0037] The system includes a belt 310, multiple sleeves 320, and multiple sliders 330. One end of the belt 310 is equipped with a buckle. Each of the multiple sleeves 320 has an internally threaded cylinder 321 rotatably connected to one side. One end of the belt 310 passes through the interior of the multiple sleeves 320 and slides inside the multiple sleeves 320. Each of the multiple sliders 330 corresponds to one of the multiple internally threaded cylinders 321. Each of the multiple sliders 330 is slidably engaged inside the annular guide rail 100, and each of the multiple sliders 330 has a screw 331 fixedly connected to one side. The outer walls of the multiple screws 331 are screwed into the inner walls of the corresponding internally threaded cylinders 321. An arc-shaped rod 332 is fixedly connected between each two adjacent sliders 330.

[0038] In practice, when a user wears the circular guide rail 100, the circular guide rail 100 can be placed around their waist, and the belt 310 can be fastened around their waist using a belt buckle. When different users have different waist sizes, the internal threaded cylinder 321 can be rotated at the same time to adjust the distance between the belt 310 and the circular guide rail 100 while fastening the belt 310.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
