Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a solar powered monitoring device. Background Art

[0002] High-voltage transmission lines are greatly affected by the geographical environment and external factors. In order to ensure the safe operation of transmission lines, online monitoring devices are currently used to monitor the lines in real time. The monitoring devices are generally installed on the towers of the lines to facilitate the monitoring of the line channels. Online monitoring devices need to be powered uninterruptedly throughout the year and take into account certain energy storage and sustainable charging functions. Therefore, solar photovoltaic panels and power batteries are often used in combination for power supply. The basic structure of a video monitoring device powered by solar energy can be found in the Chinese utility model patent with authorization announcement number CN210536758U, which discloses a video monitoring system powered by solar power generation. The monitoring system includes photovoltaic panels, power batteries and video monitors. The sunlight absorbed by the photovoltaic panels is converted into electrical energy through photovoltaic inverters and transmitted to the power batteries through wires. The power batteries can store energy and then transmit the electricity to the main body of the video monitor through wires.

[0003] In order to prevent rain, snow or hail from damaging the exposed photovoltaic panels, there is a solution in the prior art for protecting the photovoltaic panels by a rolling shutter mechanism. The rolling shutter mechanism includes a rolling shutter, a motor and a reel. The rolling shutter is wound on the reel, and the motor drives the reel to rotate to realize the winding and unwinding of the rolling shutter. The rolling shutter has a fixed end fixed to the reel and a free end that can be close to the reel when winding and away from the reel when unwinding. The rolling shutter mechanism and the photovoltaic panel are installed on a mounting frame, and the mounting frame is usually a rectangular frame adapted to the size of the photovoltaic panel. The motor and reel of the rolling shutter mechanism are arranged at one end of the mounting frame, and the photovoltaic panel is fixed on the lower side of the mounting frame. Guide grooves are provided on the opposite side frame edges of the mounting frame for the edge parts of the two sides of the rolling shutter to extend into to guide the winding and unwinding of the rolling shutter, so that when the rolling shutter is unrolled, the rolling shutter covers the top of the photovoltaic panel to protect the photovoltaic panel, and when the rolling shutter is rolled up, the photovoltaic panel is exposed.

[0004] When it snows, the photovoltaic panels are covered by rolling blinds, and the snow will fall on the rolling blinds. There will be snow accumulation on the rolling blinds. When the snow stops and the photovoltaic panels need to be exposed, the snow above the rolling blinds will fall onto the photovoltaic panels during the rolling process. The photovoltaic panels will be covered and affect their normal operation. In addition, the accumulated snow will corrode the surface of the photovoltaic panels and affect their service life.

[0025] The solar power supply monitoring device of the utility model is provided with an avoidance channel connected with the guide groove on the side of the photovoltaic panel away from the winding shaft on its mounting frame, so that the free end of the rolling curtain can extend out of the guide groove and hang down through the avoidance channel. When in use, the rolling curtain can be put into the retracted state by rolling up, and the photovoltaic panel is exposed to generate electricity normally. In snowy weather, the rolling curtain can be put into the unrolled state by unrolling, and the photovoltaic panel is covered by the rolling curtain to form a protection for the photovoltaic panel. After the snow stops, the rolling curtain can be avoided by continuing to unroll and utilizing the avoidance channel to make the free end of the rolling curtain extend out of the guide groove, and the free end of the rolling curtain loses support and hangs down, and the rolling curtain is in the hanging state, that is, the part of the rolling curtain extending out of the guide groove hangs down, and the snow accumulated on it falls off. As the unrolling proceeds, the snow accumulated on the rolling curtain can be taken away from the photovoltaic panel and fall off, so as to achieve the purpose of clearing the snow.

[0026] Embodiment of the solar power supply monitoring device of the utility model:

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, the solar power supply monitoring device in this embodiment is fixed on the pole tower 1 and is used to monitor the transmission line. The solar power supply monitoring device includes a monitor 5, a control box 7 and a photovoltaic panel 4. The control box 7 is provided with a controller 8, a battery 9 and an inverter 10. The sunlight absorbed by the photovoltaic panel 4 is converted into electrical energy through the inverter 10, and the electrical energy is transmitted to the battery 9 through the wire. The battery 9 can store energy and supply power to the monitor 5 through the wire.

[0028] The photovoltaic panel 4 in this embodiment is tilted upward, and in other embodiments, the photovoltaic panel 4 can also be horizontally arranged. In order to protect the photovoltaic panel 4, the solar power supply monitoring device includes a rolling curtain mechanism, which includes a rolling curtain 15, a motor 13 and a reel 14. The rolling curtain 15 has a fixed end fixed on the reel 14 and a free end that can be away from or close to the reel 14. The motor 13 is connected to the reel 14 to drive the reel 14 to rotate. When the reel 14 rotates, it drives the rolling curtain 15 to unwind and rewind. The rolling curtain 15 has a retracted state for exposing the photovoltaic panel 4 when rewinding and a covered state for covering the photovoltaic panel 4 when unwinding. By covering the photovoltaic panel 4 with the rolling curtain 15, the photovoltaic panel 4 can be protected.

[0029] In order to install the photovoltaic panel 4 and the rolling shutter mechanism, the solar power supply monitoring device includes a mounting frame 3. The photovoltaic panel 4 and the rolling shutter mechanism are both mounted on the mounting frame 3. The mounting frame 3 is a rectangular frame, including four side frame edges, front, back, left, and right. The front and back side frame edges are guide frame edges 35, the left side frame edge is a connecting frame edge 37, and the right side frame edge is a fixed frame edge 36. The front and back side guide frame edges 35 are symmetrically arranged front and back. The photovoltaic panel 4 is attached to the lower side of the mounting frame 3 and fixed to the mounting frame 3. Since the photovoltaic panel 4 is arranged at an angle, the mounting frame 3 is also arranged at an angle. The front side guide frame edge 35 of the mounting frame 3 is higher than the rear side guide frame edge 35. The right end of the guide frame edge 35 is provided with a thickened portion 351 with a larger thickness. The portion of the guide frame edge 35 located on the left side of the thickened portion 351 has the same thickness and is less than the thickness of the thickened portion 351. The photovoltaic panel 4 is fixed on the left side of the thickened portion 351. The thickened portions of the two guide frame edges 35 and the fixed frame edge 36 together constitute the mechanism installation end of the mounting frame 3. The thickened portions of the two guide frame edges 35 located on the thickened portion The part on the left side of 351 and the connecting frame edge 37 together constitute the main body of the mounting frame 3, so that the thickness of the mechanism mounting end is greater than the thickness of the main body, the motor 13 and the reel 14 of the rolling mechanism are installed at the mechanism mounting end of the mounting frame 3, the photovoltaic panel 4 is installed on the main body of the mounting frame 3, the motor 13 is located on the front side of the mounting frame 3 and is fixed to the front side surface of the thickened portion 351 of the front guide frame edge 35, the front and rear ends of the reel 14 are rotatably assembled on the thickened portions of the two guide frame edges 35, and the motor 13 and the reel 14 of the rolling mechanism are installed using the mechanism mounting end with larger thickness, the structural strength is good, and the installation is reliable.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, guide grooves 31 for guiding the rolling curtain 15 to unwind and rewind are provided on the two guide frame sides 35 of the mounting frame 3. The guide grooves 31 extend in the left-right direction. The notches of the guide grooves 31 on the two guide frame sides 35 are opposite to each other. The front and rear edges of the rolling curtain 15 can extend into the guide grooves 31 on both sides. When the rolling curtain 15 is unwinding and rewinding, the rolling curtain 15 can move along the guide grooves 31. The guide grooves 31 guide the movement of the rolling curtain 15 to prevent the rolling curtain 15 from slipping out. The left end of the guide frame edge 35 extends to the left side of the photovoltaic panel 4, and an avoidance groove 32 is provided on the guide frame edge 35 of the mounting frame 3 on the side of the photovoltaic panel 4 away from the reel 14, and the avoidance groove 32 is located on the left side of the photovoltaic panel 4, and the notches of the avoidance grooves 32 on the guide frame edges 35 on both sides are opposite, and the avoidance grooves 32 have downward side openings, and the avoidance grooves 32 are open downward, and the avoidance grooves 32 and the guide grooves 31 are both arranged on the inner side surface of the guide frame edge 35, and the avoidance grooves 32 and the guide grooves 31 are connected from left to right, and the avoidance grooves 32 constitute an avoidance channel, and the connecting frame edge 37 is spaced apart from the left end of the photovoltaic panel 4, and the parts of the guide frame edges 35 on both sides with the avoidance grooves 32 and the connecting frame edges 37 and the photovoltaic panel 4 form an interval space 30, and the roller shutter 15 also has a hanging state for making its free end extend out of the guide groove 31 through the avoidance channel and hang down when unwinding. In snowy weather, the rolling curtain 15 is in a shielding state to protect the photovoltaic panel 4. At this time, there will be snow on the rolling curtain 15. After the snow stops and the rolling curtain 15 needs to be retracted, the free end of the rolling curtain 15 can be extended from the guide groove 31 to the avoidance groove 32 by unwinding. Since the guide groove 31 is connected to the avoidance groove 32, the free end of the rolling curtain 15 can be extended from the guide groove 31 by using the avoidance groove 32. When the free end of the rolling curtain 15 extends to the avoidance groove 32, the avoidance groove 32 opens downward, so that the lower part of the free end of the rolling curtain 15 loses support, and the rolling curtain 15 enters a hanging state. At the same time, As the rolling curtain 15 is unrolled, the rolling curtain 15 will move towards the spacing space 30 with the accumulated snow, and the hanging part of the rolling curtain 15 will no longer support the accumulated snow above, so that the accumulated snow can fall naturally from the spacing space 30. As the unrolling continues, the accumulated snow on the rolling curtain 15 can be continuously pushed out, so as to achieve the purpose of clearing the accumulated snow. Since the rolling curtain 15 passes over the photovoltaic panel 4 and hangs down from the avoidance groove 32, it can prevent the accumulated snow from falling on the photovoltaic panel 4. After the accumulated snow is cleared, it can be rolled up again, which can reduce the impact of the accumulated snow falling on the photovoltaic panel 4 on the photovoltaic panel 4.

[0031] The downwardly open avoidance groove 32 provided on the guide frame edge 35 is used to form an avoidance channel for the rolling curtain 15 to hang down, so that the connecting frame edge 37 can be avoided from blocking the movement of the rolling curtain 15, which is conducive to the smooth hanging of the rolling curtain 15. The connecting frame edge 37 is also conducive to ensuring the structural strength of the mounting frame 3. A limiting arm is provided on the mounting frame 3 at the junction of the guide groove 31 and the avoidance groove 32. The limiting arm is a limiting piece 33. The limiting piece 33 is located above the left end of the photovoltaic panel 4. The front and rear ends of the limiting piece 33 are respectively fixed on the two guide frame edges 35. A through-slot 34 for the rolling curtain 15 to pass through is formed between the limiting piece 33 and the photovoltaic panel 4. The size of the through-slot 34 can meet the free passage of the rolling curtain 15. When the rolling curtain 15 is in the blocking state, the free end of the rolling curtain 15 extends into the through-slot 34. The limiting piece 33 can be used to limit the rolling curtain 15 above the rolling curtain 15 to prevent the rolling curtain 15 from slipping out of the guide groove 31. The limiting piece 33 is connected across the front and rear guide frame edges 35, which is beneficial to increase the strength of the mounting frame 3. When the rolling curtain 15 is retracted through the slit 34 after clearing the snow, the limiting piece 33 can scrape the rolling curtain 15 to prevent the snow from being brought back.

[0032] The rolling curtain 15 is made of transparent material, which can reduce the impact of the rolling curtain 15 covering the photovoltaic panel 4 on the power generation of the photovoltaic panel 4. The rolling curtain 15 can be wound on the reel 14, and the rolling curtain 15 has a certain hardness. When unrolling, the rolling curtain 15 can be pushed to stretch out through the action force between the parts of the rolling curtain 15 itself. When the rolling curtain 15 moves, it can push the snow to pass the limiting piece 33 and fall from the interval space 30.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, in order to fix the installation frame 3, the monitor 5 and the control box 7, the device also includes a support crossarm 2, a clamp 11, a bracket 12 and a fixing hardware 6. The end surface of the support crossarm 2 is provided with a clamp fixing hole 21, and the side surface of the support crossarm 2 is provided with a bracket fixing hole 22, a hardware fixing hole 23 and a control box fixing hole 24 from left to right. The clamp 11 is used to clamp on the tower 1. The clamp 11 includes two hoop pieces. The two sides of the hoop piece are provided with fixing ears 111. The two fixing ears 111 are one long and one short. The longer fixing ear 111 is fixed to the support crossarm 2 by bolts in conjunction with the clamp fixing hole 21. The bracket 12 constitutes a frame fixing structure for fixing the installation frame 3. The bracket 12 is a tripod. The bracket 12 is fixed to the support crossarm 2 by bolts in conjunction with the bracket fixing hole 22. The bracket 12 is fixed to the mechanism installation end of the installation frame 3, that is, the end of the installation frame 3 where the reel 14 is rotatably installed is fixed to the bracket 12, which is conducive to reliable installation. The monitor 5 is fixed on the fixing hardware 6, which constitutes the fixing structure of the monitor. The fixing hardware 6 is fixed on the supporting crossarm 2 by bolts matching the hardware fixing holes 23. The control box 7 is fixed on the supporting crossarm 2 by bolts matching the control box fixing holes 24. The bracket 12, the fixing hardware 6 and the control box 7 are fixed on the same side of the supporting crossarm 2, which has a compact structure and is easy to maintain.

[0034] In other embodiments, the photovoltaic panel can also cover the lower frame opening of the mounting frame. In this case, a long hole is opened on the side of the connecting frame. The long hole passes through the left and right sides and is connected to the guide groove on the side of the guide frame. The long hole forms an avoidance channel, and the free end of the roller shutter can pass through the long hole and extend out of the mounting frame, thereby causing the free end of the roller shutter to lose support and hang down.

[0035] In other implementations, the limiting arm may not be provided, and the rolling blind may be limited only by the upper groove wall of the guide groove.

[0036] In other implementations, the limiting arm may also be a cantilever arm, one end of which is connected to an edge of the guide frame and the other end of which is suspended in the air.

[0037] In other implementations, the rolling blind may also be made of opaque material.

[0038] In other implementations, the monitor and the mounting frame may also be installed at different locations on the tower.
