Description

Technical Field

[0001] This invention relates to the field of temporary power supply, specifically to a construction-use solar temporary power generation device with a protective structure. Background Technology

[0002] On construction sites, especially in high-rise environments, as the demand for temporary power increases, and in situations where it is not convenient to connect to municipal power or where it is necessary to reduce the noise and pollution from diesel generators, using solar panels to build temporary power generation equipment has become a green and convenient way to supply electricity. Temporary power generation equipment built with solar panels has certain requirements on the size of the site to ensure the gap between the generated electricity and the on-site electricity consumption.

[0003] Construction sites typically involve working at heights, densely packed materials, and numerous temporary components, making wind a significant factor affecting on-site safety. For example, during pipeline construction, steel structure installation, and formwork erection, tools, packaging materials, and lightweight components are at risk of being blown away or impacted by strong winds. If solar panels lack adequate protective structures, they are not only easily damaged by wind loads but may also be blown away by the wind, colliding with surrounding personnel and facilities. Furthermore, construction sites generate a lot of dust, falling debris, and frequent machinery traffic. If the surface of solar panels lacks necessary protection, it is also susceptible to impacts from sand and gravel, as well as falling objects, affecting their power generation efficiency and lifespan. Therefore, we propose a temporary solar power generation device for construction sites with a protective structure. Summary of the Invention

[0004] The purpose of this invention is to provide a temporary solar power generation device for construction with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a temporary solar power generation device for construction with a protective structure is provided, comprising a main body of the solar power generation device, which includes a solar panel and a battery. A protective unit is provided on the outside of the main body of the solar power generation device. The protective unit includes a detection component and a protection component. The detection component includes an omnidirectional turbine, a one-way clutch, and a drive mechanism. The protection component includes a winding mechanism, an unwinding mechanism, and a protective net. There are two omnidirectional turbines, which are used to detect the wind force. The one-way clutches on the lower sides of the two omnidirectional turbines rotate in opposite directions to adapt to the omnidirectional turbines being driven in any direction under external wind force. The drive mechanism is used to control the winding mechanism to wind up when the omnidirectional turbine speed reaches a preset value. A rotation damper and a coil spring are respectively provided at both ends of the unwinding mechanism. The protective net includes an outer layer and a magnetic fluid. One end of the magnetic fluid is electrically connected to the solar panel. A pressure sensor is provided at the contact position between the winding mechanism and the protective net.

[0006] Furthermore, the driving mechanism includes a driving rod, the lower end of which is fixedly mounted at the center of the upper surface of the cam, and a plurality of movable teeth are slidably connected to the lower surface of the cam.

[0007] Furthermore, the winding mechanism includes a collection housing, and a winding roller is rotatably connected inside the collection housing. Both ends of the winding roller are fixedly mounted with helical gears, and the outer ring of the helical gears meshes with the movable teeth.

[0008] Furthermore, the unwinding mechanism includes an unwinding housing, an unwinding roller rotatably connected inside the unwinding housing, a protective net wrapped around the surface of the unwinding roller, and a rotary damper and a movable end of a coil spring fixedly installed at both ends of the unwinding roller, respectively.

[0009] Furthermore, the movable end of the protective net is fixedly installed on the traction rod, and guide blocks are fixedly installed at both ends of the traction rod. The lower end of the guide block is slidably connected to the main body of the solar power generation equipment, and the lower end of the guide block is provided with a roller. The top of the main body of the solar power generation equipment is provided with a guide groove that matches the size of the lower end of the guide block.

[0010] Furthermore, a traction rope is fixedly connected to one end of the traction rod away from the unwinding mechanism, and the other end of the traction rope is fixedly connected to the take-up roller.

[0011] Furthermore, a contact port adapted to the size of the guide block is provided on the opposite side between the collecting shell and the unwinding shell, and a pressure sensor is fixedly installed on the inner wall of the contact port corresponding to the collecting shell.

[0012] Furthermore, the lower surface of the convex disk is provided with a smooth arc-shaped surface that gradually decreases from the outside to the inside, and the arc-shaped surface is provided with a groove that matches the size of the movable tooth.

[0013] Furthermore, the size of the protective net is adapted to the overall size of the solar panel.

[0014] Furthermore, the traction rope is a double-braided polyester rope with an outer layer treated to resist ultraviolet radiation.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this solution, when the wind force reaches the set threshold, the movable gear in the drive mechanism expands outward through centrifugal force and meshes with the helical gear, driving the winding roller to wind up the traction rope, so that the protective net can automatically rise with the wind. This structure uses natural wind energy to complete the winding action, reducing the additional energy consumption requirements at the construction site.

[0017] 2. In this scheme, two omnidirectional turbines are used in conjunction with one-way clutches in opposite directions. Regardless of the direction of the wind, one of the omnidirectional turbines can output effective torque to the drive mechanism, while the other omnidirectional turbine idles under the action of the one-way clutch. This avoids control failure caused by changes in wind direction and achieves stable determination of wind force level.

[0018] 3. In this solution, the rotation damper in the unwinding mechanism works in conjunction with the coil spring. The coil spring provides the restoring force, and the damper limits the descent speed, so that the protective net can smoothly transition during the process of retracting or covering the solar panel, avoiding impact on the solar panel from instantaneous descent.

[0019] 4. In this solution, the magnetic fluid curing gives the protective netting temporary structural rigidity, which can both support the protective space and maintain a relatively stable deployment position in high wind environments, further enhancing the safety protection of the construction site.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] A temporary solar power generation device for construction with a protective structure, such as Figure 1-7 As shown, the device includes a main body 1 of a solar power generation device, which includes a solar panel 2 and a battery 3. A protection unit is provided on the outside of the main body 1. The protection unit includes a detection component 4 and a protection component 5. The detection component 4 includes an omnidirectional turbine 6, a one-way clutch 7, and a drive mechanism 8. The protection component 5 includes a winding mechanism 9, an unwinding mechanism 10, and a protective net 11. There are two omnidirectional turbines 6, which are used to detect the wind force. The one-way clutches 7 on the lower side of the two omnidirectional turbines 6 rotate in opposite directions to accommodate rotation of the omnidirectional turbines 6 in any direction. The drive mechanism 8 is used to control the winding mechanism 9 to wind up when the rotation speed of the omnidirectional turbines 6 reaches a preset value. The two ends of the unwinding mechanism 10 are respectively provided with a rotation damper 12 and a coil spring 13. The rotation damper 12 is used to control the protective net 11 to slowly fall back under the tension of the coil spring 13. The protective net 11 includes an outer layer 14 and a magnetic fluid 15. One end of the magnetic fluid 15 is electrically connected to the solar panel 2. A pressure sensor 16 is provided at the contact position between the winding mechanism 9 and the protective net 11.

[0031] Specifically, the drive mechanism 8 includes a drive rod 17, the lower end of which is fixedly installed at the center of the upper surface of the cam 18. Several movable teeth 19 are slidably connected to the lower surface of the cam 18. The drive rod 17 drives the cam 18 to rotate. After the omnidirectional turbine 6 reaches the set value, the movable teeth 19 can approach the outer ring of the cam 18 under the action of centrifugal force and then mesh with the helical gear 22.

[0032] Specifically, the winding mechanism 9 includes a collection housing 20, and a winding roller 21 is rotatably connected inside the collection housing 20. Both ends of the winding roller 21 are fixedly mounted with helical gears 22, and the outer ring of the helical gears 22 meshes with the movable teeth 19. The winding roller 21 rotates by meshing the helical gears 22 with the movable teeth 19 on the cam 18. The cam 18 can only mesh with the helical gears 22 when the omnidirectional turbine 6 rotates fast enough, that is, when the wind speed is fast enough and the wind force is strong enough, the winding roller 21 can rotate and pull up the protective net 11.

[0033] The unwinding mechanism 10 includes an unwinding housing 23, an unwinding roller 24 rotatably connected inside the unwinding housing 23, a protective net 11 wrapped around the surface of the unwinding roller 24, and a rotary damper 12 and a coil spring 13 fixedly installed at both ends of the unwinding roller 24, respectively. The coil spring 13 is used to control the reset and rewinding of the protective net 11, and the rotary damper 12 is used to control the protective net 11 to slowly fall back under the tension of the coil spring 13.

[0034] It is understood that the movable end of the protective net 11 is fixedly installed on the traction rod 25, and guide blocks 26 are fixedly installed at both ends of the traction rod 25. The lower end of the guide block 26 is slidably connected to the main body 1 of the solar power generation equipment, and the lower end of the guide block 26 is provided with a roller 27. The top of the main body 1 of the solar power generation equipment is provided with a guide groove 28 that matches the size of the lower end of the guide block 26. The end of the traction rod 25 away from the unwinding mechanism 10 is fixedly connected to the traction rope 29, and the other end of the traction rope 29 is fixedly connected to the take-up roller 21. The take-up roller 21 pulls the traction rod 25 through the traction rope 29 to pull out the protective net 11. The guide block 26 is used to control the direction so that it does not deviate during the process. When the protective net 11 is inside the unwinding mechanism 10, only the traction rope 29 is located between the take-up mechanism 9 and the unwinding mechanism 10, which will not affect the power generation of the solar panel 2.

[0035] To facilitate stable contact between one end of the guide block 26 and the collecting shell 20 or the unwinding shell 23, a contact port 30 adapted to the size of the guide block 26 is provided on the opposite side between the collecting shell 20 and the unwinding shell 23. A pressure sensor 16 is fixedly installed on the inner wall of the contact port 30 corresponding to the collecting shell 20 to detect the pressure of the guide block 26 on the inner wall of the contact port 30 under the tension of the traction rope 29. When the wind force is too strong, the pressure sensor 16 reaches the preset value, and the magnetic fluid 15 inside the battery 3 discharges and controls the protective net 11 to solidify for a certain period of time, supporting a relatively rigid protection on the upper side of the solar panel 2. Due to the hardening of the protective net 11, the protective net 11 is also controlled to stop moving down for a certain period of time, thus completing the stable protection.

[0036] The lower surface of the convex plate 18 is provided with a smooth arc-shaped surface that gradually decreases from the outside to the inside. The arc-shaped surface is provided with a sliding groove that matches the size of the movable tooth 19 to stabilize the movement of the movable tooth 19.

[0037] The size of the protective net 11 is adapted to the overall size of the solar panel 2 for all-round protection, and the traction rope 29 is a double-braided polyester rope with an anti-ultraviolet treatment on the outer layer.

[0038] In this embodiment, it is understood that when the wind force in the construction site reaches a preset value, capable of blowing tools, packaging materials, lightweight components, and other objects, the omnidirectional turbine 6 will also be blown by the airflow and rotate at a high speed. The lower ends of the two omnidirectional turbines 6 are equipped with one-way clutches 7 that limit the direction of rotation to opposite directions. Because the omnidirectional turbines 6 are arranged close together, their rotation is affected by the wind direction and they rotate in the same direction. Under the action of the one-way clutches 7, the omnidirectional turbine 6 rotating in the opposite direction to the starting direction of the winding mechanism 9 is restricted by the one-way clutches 7 and will only rotate idly. The omnidirectional turbine 6 rotating in the same direction as the starting direction of the winding mechanism 9 will be driven by its lower one-way clutches 7, controlling the winding roller 21 to wind up the traction rope 29 through the protective net 11, thereby pulling up the protective net 11. When the wind force is too strong, the pressure sensor 16 experiences pressure reaching a preset value. The magnetic fluid 15 inside the battery 3 discharge control protective net 11 solidifies for a certain period of time, supporting a relatively rigid protection on the upper side of the solar panel 2. Due to the hardening of the protective net 11, it also controls the protective net 11 to stop moving down for a certain period of time, thus completing stable protection. The coil spring 13 is used to control the reset and rewind of the protective net 11. The rotary damper 12 is used to control the protective net 11 to slowly fall back under the tension of the coil spring 13. In environments with large wind changes and strong winds coming in gusts, by controlling the fall speed of the protective net 11, it is also possible to control the protective net 11 to slowly cover the solar panel 2. Under normal wind conditions, the protective net 11 is slightly unfolded or not unfolded. When the wind force reaches the preset value, the protective net 11 can automatically and quickly roll up. When the wind force is too strong, the pressure triggers the magnetic fluid 15 to solidify and form a reinforced protection.

[0039] It should also be noted that, in the embodiments, the omnidirectional turbine 6, the one-way clutch 7, and the rotary damper 12 are all prior art. The application of the omnidirectional turbine 6 in the prior art can be referred to the omnidirectional turbine generator. The actual application of the one-way clutch 7 in the prior art is in automobiles and motorcycles, such as gearboxes and engine starting systems. The most common example can be referred to as bicycle ratchet. The application of the rotary damper 12 in the prior art can be referred to as the opening and closing of a laptop computer. The principles of such prior art will not be elaborated further here.

[0040] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
