Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket mechanism used in deserts. Background Art

[0002] "Photovoltaic sand control" is an innovative desert control model that combines photovoltaic power generation technology with desert control. By installing photovoltaic brackets in the desert, it can not only generate electricity, but also play a role in sand fixation and ecological restoration. Photovoltaic panels can block sunlight, reduce the evaporation of surface water, reduce wind speed, improve soil conditions, and create a favorable environment for vegetation restoration. At the same time, the shaded area under the photovoltaic panels also provides the possibility for the growth of sand plants, thereby promoting ecological restoration and biodiversity improvement in desert areas.

[0003] When installing existing desert photovoltaic brackets, large-diameter cement piles are first used for piling, and then the brackets are fixed on the cement piles. Subsequently, photovoltaic panels with larger areas are installed on multiple photovoltaic brackets. This installation method can ensure the supporting strength between photovoltaic panels.

[0004] However, in desert areas, there are frequent sandstorms and loose and porous soil. When photovoltaic brackets are used for a long time, the soil at individual brackets is prone to loosening. Loosening the soil will cause the cement piles and the photovoltaic brackets thereon to sink, tilt or be damaged. Since the area of photovoltaic brackets in the desert is large, it is often impossible for humans to find problematic brackets in time, which can lead to unstable support of photovoltaic panels and even the overall collapse of the photovoltaic brackets and photovoltaic panels.

Specific embodiments

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0041] Please refer to Figures 1 to 4, a photovoltaic support mechanism for deserts, comprising parallel hollow beams 1, beam brackets 12, vertical beams 13, connecting members 11 and cement piles 2. There are three of the parallel hollow beams 1, beam brackets 12 and cement piles 2 respectively. The three beam brackets 12 support and hold up the three parallel hollow beams 1 among them. The vertical beam 13 includes a left support beam 131 and a right support beam 132, and the left support beam 131 and the right support beam 132 are used to support the beam brackets 12 thereon. The connecting member 11 is located between the left support beam 131 and the right support beam 132, and the connecting member 11 is detachably installed on the cement pile 2. The connecting member 11 is of an existing structure. As an implementation manner, the connecting member 11 can be a clamp, that is, multiple clamps fixedly install the left support beam 131 and the right support beam 132 on the outer sides of the tops of the cement piles 2 respectively, further realizing the stable support for the parallel hollow beam 1, beam bracket 12 and vertical beam 13. At the same time, in this example, it is preferably that three cement piles 2 form a group, and the parallel hollow beams 1, beam brackets 12, vertical beams 13 and connecting members 11 on the three cement piles 2 support the photovoltaic panels with each other:

[0042] A fixing seat 3 is fixedly installed at the top of the cement pile 2 and between the left support beam 131 and the right support beam 132, and the fixing seat 3 is fixed to the top of the cement pile 2 by welding, thereby ensuring the support stability of the fixing seat 3. At the same time, there are reinforcing ribs on the fixing seat 3, thereby ensuring the support strength of the fixing seat 3;

[0043] Two fixing plates 4 are arranged above the fixing seat 3, and the two fixing plates 4 are respectively fixedly installed on the left support beam 131 and the right support beam 132 by bolts;

[0044] Two support shafts 5 are fixedly installed between the two fixing plates 4, and a detection mechanism 6 is installed between two adjacent support shafts 5 above the two cement piles 2. The detection mechanism 6 is used to detect the state of the cement pile 2 and the photovoltaic support at the position of the cement pile 2. Thus, when the support is damaged and causes a change in the position state of the support shaft 5 among them, or when the cement pile 2 sinks and causes a change in the position state of the support shaft 5, the detection mechanism 6 can detect the change in the state of the photovoltaic support in time;

[0045] Please refer to Figures 5 to 8 , the detection mechanism 6 includes a first connection block 61, a second connection block 62, a connecting rod 63, a connecting sleeve 64, a detection piece 65 and a spreading piece 8. The first connection block 61 and the second connection block 62 are respectively rotatably sleeved on two adjacent support shafts 5 above the two cement piles 2. One end of the connecting rod 63 is fixedly connected to the first connection block 61, and one end of the connecting sleeve 64 is fixedly connected to the second connection block 62. The other end of the connecting rod 63 is slidably connected inside the connecting sleeve 64;

[0046] The detection member 65 is installed inside the connecting sleeve 64 and connected to the connecting rod 63;

[0047] One end of the connecting rod 63 close to the inside of the connecting sleeve 64 is provided with a cavity 631, and the expanding member 8 is located at the cavity 631. When the detection member 65 detects a change in the supporting state of the photovoltaic bracket, the expanding member 8 is used to strengthen the supporting strength between the connecting rod 63 and the supporting sleeve 73.

[0048] The detection member 65 includes a pressure sensor 651, a detection plate 652, a connecting spring 653 and a positioning plate 654. The pressure sensor 651 is fixedly installed at one end inside the connecting sleeve 64. The detection plate 652 is fixedly installed on the pressure sensor 651. When the pressure sensor 651 sends a signal value to the control terminal and it is judged by the control terminal that the signal value at the pressure sensor 651 has changed, a timely warning is given. And this control terminal can be the mobile phone terminal of the staff or the computer terminal, and can receive the signal in time to judge the bracket with the changed state;

[0049] The detection plate 652 is slidably sleeved outside the connecting rod 63, the positioning plate 654 is fixedly sleeved outside the connecting rod 63, the connecting spring 653 is sleeved outside the connecting rod 63, and both ends of the connecting spring 653 are fixedly connected to the detection plate 652 and the positioning plate 654 respectively.

[0050] Specific implementation process: In the harsh desert environment, when the photovoltaic bracket is slightly damaged due to the influence of strong wind or the loosening and loss of the soil at the cement pile 2, or the cement pile 2 sinks slightly, the connecting rod 63 connected to the damaged cement pile 2 and the connecting sleeve 64 move relative to each other. When the connecting rod 63 and the connecting sleeve 64 move relative to each other, the corresponding connecting spring 653 undergoes elastic deformation, that is, the connecting spring 653 is compressed or stretched. At this time, the corresponding detection plate 652 is subjected to extrusion or stretching, and the signal value at the corresponding pressure sensor 651 changes. Then the pressure sensor 651 sends the signal to the control terminal, and a timely warning is given through the control terminal, so as to notify the staff and enable timely maintenance of the damaged photovoltaic bracket or the sunken cement pile 2.

[0051] Please refer to Figures 6 to 8, the expansion member 8 includes an iron rod 81, an iron block 82, a buffer spring 83, a contact member 84 and a sensing member 85. One end of the iron rod 81 slidably penetrates through the cavity 631 of the connecting rod 63. The iron block 82 is fixedly installed at one end of the iron rod 81 and is slidably connected inside the cavity 631. The buffer spring 83 is sleeved outside the iron rod 81, and both ends of the buffer spring 83 are fixedly connected to the cavity 631 and the iron block 82 respectively. The sensing member 85 is located inside the cavity 631 and at the end away from the iron block 82;

[0052] The contact member 84 is installed on the iron rod 81 and at the end outside the cavity 631.

[0053] The sensing member 85 includes an electromagnet 851 fixedly installed at one end inside the cavity 631, and the power supply for energizing the electromagnet 851 can be provided by the photovoltaic panel, so as to ensure the stable energization of the electromagnet 851. At the same time, in this embodiment, the connecting sleeve 64 is made of steel plate material, and using steel plate material can effectively block the magnetic field, reduce the attraction of the electromagnet 851, and reduce electromagnetic interference.

[0054] The contact member 84 includes an arc plate 841, a first positioning seat 842, a second positioning seat 843, a moving support rod 844, a positioning support rod 845, a moving seat 846 and a fixing frame 847;

[0055] There are multiple arc plates 841. Multiple anti-slip grooves 8411 are provided on the outer side of the arc plate 841. The arc plates 841 are arranged around the iron rod 81. The first positioning seat 842 and the second positioning seat 843 are respectively fixedly installed at both ends of the inner surface of the arc plate 841. One end of the moving support rod 844 is hinged to the first positioning seat 842 through a pin shaft, and the other end of the moving support rod 844 is hinged to the moving seat 846 through a pin shaft. A rotating shaft is rotatably connected between the moving support rod 844 and the positioning support rod 845;

[0056] Multiple moving seats 846 are all fixedly installed around the outer side of one end of the iron rod 81;

[0057] One end of the positioning support rod 845 is hinged to the second positioning seat 843 through a pin shaft, and the other end of the positioning support rod 845 is hinged to the fixing frame 847 through a pin shaft. Multiple fixing frames 847 are all fixedly installed at one end of the connecting rod 63.

[0058] Specific implementation process: When the photovoltaic support is damaged or the cement pile 2 at the photovoltaic support sinks, the pressure sensor 651 detects the signal and sends it to the control terminal. At this time, the electromagnets 851 at the two connecting rods 63 outside the corresponding photovoltaic support are energized. When the electromagnet 851 is energized, the iron block 82 is subjected to the adsorption force of the electromagnet 851 and thus moves along the direction of the electromagnet 851 until one end of the iron block 82 is in stable contact with the electromagnet 851. While the iron block 82 moves along the electromagnet 851, it drives the iron rod 81 to move synchronously. One end of the iron rod 81 moves along the inside of the cavity 631. While the iron rod 81 moves, a plurality of moving seats 846 at the other end thereof move synchronously. While the moving seat 846 moves, it drives a plurality of moving support rods 844 thereon to rotate. Due to the limiting effect of the positioning support rod 845 on the moving support rod 844, the two ends of the positioning support rod 845 rotate relative to the fixed frame 847 and the arc-shaped plate 841 respectively. At this time, a plurality of arc-shaped plates 841 move along the inner wall of the connecting sleeve 64 until the plurality of iron blocks 82 and the iron rod 81 stop moving. The plurality of arc-shaped plates 841 cooperate with the inner wall of the connecting sleeve 64, that is, the plurality of arc-shaped plates 841 are in contact with the connecting sleeve 64 to realize the relative fixation between the connecting rod 63 and the connecting sleeve 64. At this time, when the damaged photovoltaic support or the cement pile 2 at the photovoltaic support sinks, the two connecting rods 63 outside it and the connecting sleeve 64 can be relatively fixed, playing a role in assisting the support of the photovoltaic support with a changed state, minimizing the deformation or sinking movement generated by the photovoltaic support to the greatest extent, and thus being able to ensure the stability of the overall photovoltaic support and the overall photovoltaic panel. During this process, it can wait until the staff repairs the photovoltaic support with a changed state.

[0059] At one end where the two fixed seats 3 are close to each other, a support member 7 is provided therebetween. The support member 7 is used to support the detection mechanism 6, that is, to realize the re-stable connection between adjacent fixed seats 3 through the support member 7.

[0060] Please refer to Figures 4 to 5 The support member 7 includes a reinforcing rod 71, a reinforcing base 72, and a support sleeve 73. The reinforcing base 72 is fixedly installed on the fixed seat 3 through a locking bolt. The bottom of the reinforcing rod 71 is hinged to the reinforcing base 72 through a pin shaft. The top of one of the reinforcing rods 71 is rotationally connected to the outside of the connecting sleeve 64 through a hinge support, and the bottom of the other reinforcing rod 71 is rotationally connected to the support sleeve 73 through a hinge support. The support sleeve 73 is fixedly sleeved on the outside of the connecting rod 63;

[0061] The support member 7 synchronously supports the connecting sleeve 64 or the connecting rod 63. Embodiment 2

[0062] Please refer to Figure 9 , two moving holes 632 are provided on the connecting rod 63, the two moving holes 632 communicate with the cavity 631, and a locking member 9 is provided on the outer side of the connecting rod 63 at a position corresponding to the moving holes 632.

[0063] The locking member 9 includes a locking block 91, a side plate 92, a locking rod 93, a locking plate 94 and a locking spring 95. The locking block 91 slidably penetrates through the moving hole 632, and one end of the locking block 91 located inside the moving hole 632 is arc-shaped. At the same time, the side of the iron block 82 close to the locking block 91 is provided with a chamfer. The side plate 92 is slidably sleeved on the outer side of the locking rod 93, and the side plate 92 is fixedly installed on the outer side of the connecting rod 63. One end of the locking rod 93 is fixedly connected to the locking block 91, and the other end of the locking rod 93 is fixedly connected to the locking plate 94. The locking spring 95 is sleeved on the outer side of the locking rod 93, and both ends of the locking spring 95 are fixedly connected to the locking plate 94 and the side plate 92 respectively. The locking plate 94 is fixedly connected to the locking rod 93.

[0064] Specific implementation process: With the setting of this embodiment, in order to ensure the stability of the connection between the iron block 82 and the electromagnet 851, when the iron block 82 moves along the electromagnet 851, the arc-shaped end on one side thereof contacts the locking block 91 and pushes the locking block 91 to move along the moving hole 632. Until one side of the iron block 82 is adsorbed and connected to the electromagnet 851, the locking rod 93 moves along the moving hole 632 through the locking plate 94 under the reverse elastic force of the locking spring 95. Then, the two locking blocks 91 further limit and clamp the iron block 82, thereby ensuring the tightness of the connection between the iron block 82 and the electromagnet 851, and further ensuring the relative fixation between the connecting rod 63 and the connecting sleeve 64;

[0065] At the same time, in the embodiment, the connecting sleeve 64 is composed of two half sleeves. That is, when repairing and resetting a damaged bracket or a sunken bracket, the connecting sleeve 64 can be disassembled. At the same time, the electromagnet 851 is powered off, and the two locking plates 94 are respectively pushed to make the two locking blocks 91 disengage from the iron block 82 respectively, and further make the iron block 82 disengage from the electromagnet 851.
