[0002] With the continuous development and maturity of solar thermal power generation technology, and the pressure of dual carbon targets, domestic oil fields have begun to explore the integrated development of oil and gas exploration and development with new energy technologies such as solar thermal power generation. In particular, with the continuous growth of global energy demand, solar thermal power generation technology has received more and more attention in the development and utilization of oil and gas fields. Traditional oil and gas field wellhead equipment (pumping units, wellhead heating furnaces, oil storage tanks, lighting and monitoring facilities) usually rely on fossil fuels or diesel engines for power generation, which not only has high operating costs, but also causes serious pollution to the environment. The use of solar photovoltaic power generation can effectively reduce operating costs and reduce carbon emissions from equipment operation.

[0033] like Figure 1-Figure 9 As shown, a mobile off-grid solar photovoltaic power generation and energy storage system provided by an embodiment of the utility model includes a photovoltaic power generation mechanism and a trailer 3, wherein:

[0034] The photovoltaic power generation mechanism includes a photovoltaic panel 1 and a bracket 2. The photovoltaic panel 1 is installed on the upper end of the bracket 2. A plurality of brackets 2 are arranged at equal intervals along the length direction of the photovoltaic panel 1 so that the photovoltaic panel 1 is stably supported. Figure 1 The width direction of the photovoltaic panel 1 is shown. Since the brackets 2 are arranged at equal intervals along the length direction of the photovoltaic panel 1, Figure 1 In the view, the brackets 2 overlap each other, and only one group of brackets 2 at the end of the photovoltaic panel 1 can be seen;

[0035] The trailer 3 includes a traction frame 31 and a frame 32. The traction frame 31 is rotatably mounted on the front end of the frame 32. The traction frame 31 and the frame 32 are both existing technologies and can be directly applied without further explanation. A bearing plate 33 is fixedly connected to the frame 32. A long groove 331 for limiting the lower end of the bracket 2 is opened on the bearing plate 33 along its own length direction, and a limiting mechanism for limiting the bracket 2 is provided on the bearing plate 33.

[0036] The bracket 2 includes a main support rod 21 and two auxiliary support rods 22. The main support rod 21 includes a support rod 211 and a support 212 that are connected to each other. The upper end of the support rod 211 is rotatably connected to the upper end of the photovoltaic panel 1, and the lower ends of the two auxiliary support rods 22 are rotatably connected to the support 212, and the upper ends of the two auxiliary support rods 22 are respectively rotatably connected to the two sides of the photovoltaic panel 1. Preferably, the two auxiliary support rods 22 are both retractable structures, so that the inclination angle of the photovoltaic panel 1 can be adjusted according to the actual use site, so that the photovoltaic panel 1 can receive the optimal lighting time and light intensity.

[0037] Specifically, the photovoltaic power generation energy storage system also includes an energy storage component and a control system, wherein the energy storage component can adopt existing technologies such as lithium-ion batteries, lead-acid batteries or supercapacitors, and the control system includes a controller and an inverter. The controller and the inverter are both existing technologies and can be directly applied without further elaboration. The inverter is used to convert DC points into AC power for use by AC loads (AC electrical appliances), and the DC load is directly electrically connected to the energy storage component. Its structural block diagram is shown as follows: Fig. 9 shown.

[0038] When installing the photovoltaic power generation mechanism, it is necessary to cast a cement base at the layout site and set embedded parts in the base. The embedded parts and the support 212 cooperate with each other to achieve the connection between the photovoltaic power generation mechanism and the cement base.

[0039] One end of the long groove 331 extends to the end of the supporting plate 33 away from the traction frame 31, and a supporting block 4 is slidably installed in the long groove 331. In actual use, the supporting block 4 can be taken out from one end of the long groove 331, and the lower part of the supporting block 4 is rotatably connected to the roller 41, and the roller 41 is symmetrically arranged in two rows about the supporting block 4. When the supporting block 4 slides along the long groove 331, the roller 41 contacts the bottom of the long groove 331 to reduce the sliding resistance of the supporting block 4. A limiting hole 2121 is provided inside the support 212, and a limiting rod 42 matching the limiting hole 2121 is fixedly connected to the supporting block 4. The end of the above-mentioned embedded part can cooperate with the support 212 through the limiting hole 2121. The embedded part can preliminarily limit the bracket 2 to maintain the position of the bracket 2 and the photovoltaic panel 1, so as to facilitate the connection and fixation between the bracket 2 and the embedded part.

[0040] The limiting mechanism includes a plurality of limiting blocks 5 rotatably connected to the bearing plate 33, and the plurality of limiting blocks 5 are arranged at equal intervals along the length direction of the bearing plate 33, such as Figure 6 and Figure 7 As shown, the cross section of the limit block 5 is fan-shaped, and one side of the bearing block 4 is arc-shaped and adapted to the arc surface of the limit block 5. A torsion spring is mounted on the rotation axis of each limit block 5, and the torsion spring can keep the limit block 5 from rotating outward on the bearing plate 33, and each limit block 5 is arranged in the long groove 331. When the bearing block 4 slides from the rear side of the frame 32 to the front side along the long groove 331, the limit block 5 is squeezed and rotated to the inside of the bearing plate 33. In specific implementation, the front end closest to the bearing plate 33, i.e. Figure 3 The set of limit plates on the left side of the view is at a certain distance from the left end of the long slot 331, and the distance is the same as the dimension of the bearing block 4 along the length direction of the long slot 331, so that the bearing block 4 can slide to the long slot 331 at a certain distance. Figure 3 When viewing the left end of the figure, the limiting plate closest to the front end of the carrying plate 33 can be smoothly rotated outwards and cooperate with the carrying plate 33 to limit the position of the carrying block 4.

[0041] The bearing plate 33 is provided with a protrusion 332 along the length direction of the long groove 331. The length of the protrusion 332 is equal to the length of the long groove 331. The two rows of rollers 41 are respectively located on both sides of the protrusion 332. The limit blocks 5 are installed in the protrusion 332. Figure 2 and Figure 4 As shown, when the limit block 5 is pushed from the long groove 331 to Figure 3 When the right end slides toward the left end in the view, the carrying plate 33 contacts the limiting block 5 and presses the limiting block 5 into the interior of the protrusion 332 .

[0042] Preferably, the long groove 331 includes a first groove 3311, a second groove 3312 and a third groove 3313 which are connected in sequence, and the lengths of the first groove 3311, the second groove 3312 and the third groove 3313 are equal, so that the cross-section of the long groove 331 is stepped. When the bracket 2 is placed in the first groove 3311, the second groove 3312 and the third groove 3313, the widths gradually decrease, the size of the supporting block 4 along the width direction of the supporting plate 33 is equal to the width of the first groove 3311, and the diameter of the lower part of the support 212 is equal to the width of the second groove 3312.

[0043] When the photovoltaic panel 1 needs to be moved over a long distance, the bracket 2 is removed from the embedded part, and the photovoltaic panel 1 and the bracket 2 are hoisted as a whole. The bearing block 4 is placed at the lower part of the bracket 2 through the cooperation of the limiting rod 42 and the limiting rod 42, and the bracket 2 and the bearing block 4 are moved together to the inside of the long groove 331, as shown in FIG. Figure 2In the state shown, at this time, the support 212 on the bracket 2 is in the second groove 3312, the bearing block 4 is in the third groove 3313, and the main support rod 21 and the two auxiliary support rods 22 extend outward from the third groove 3313, and the support 212 and the bearing block 4 are restricted by the long groove 331 and can only move along the length direction of the long groove 331; then, the photovoltaic panel 1 and the bracket 2 are pushed along the length direction of the long groove 331 to move until the other bracket 2 is close to the end of the long groove 331, and the other bearing block 4 is placed at the lower part of the other bracket 2 according to the above operation, and so on, until the bearing blocks 4 are placed at the lower part of all the brackets 2, and all the brackets 2 are placed in the long groove 331;

[0044] When the supporting block 4 is driven to slide along the long groove 331 and contact the limit block 5, the limit block 5 is pressed into the interior of the protrusion 332. After the supporting block 4 passes over the limit block 5, the limit block 5 is driven by the torsion force of the corresponding torsion spring to rotate outward from the inside of the protrusion 332 again, blocking the supporting block 4 and preventing the supporting block 4 from sliding in the opposite direction along the long groove 331. When the first group of supporting blocks 4 passes over the last group of limit blocks 5, that is, the limit blocks 5 closest to the above-mentioned traction frame 31, and reaches the end of the long groove 331, after the group of limit blocks 5 rotates out, the first group of supporting blocks 4 is restricted by the supporting plate 33 and the group of limit blocks 5 and cannot move in the long groove 331, thereby realizing the limiting connection between the bracket 2 and the supporting plate 33, ensuring that the bracket 2 and the photovoltaic panel 1 will not move on the supporting plate 33 during the movement of the trailer 3.

[0045] A number of rubber blocks 51 are fixedly connected to the limit block 5, and a number of circular protrusions 43 are protruded from the middle of the lower surface of the supporting block 4. When the limit block 5 is squeezed and rotated to the inside of the supporting plate 33, the surface of the limit block 5 with the rubber block 51 is flush with the upper surface of the protrusion 332, so that when the supporting block 4 moves along the limit block 5, the circular protrusion 43 and the rubber block 51 contact, which has a certain deceleration effect on the supporting block 4, preventing the supporting block 4 from moving too fast and hitting the end of the long groove 331 when it reaches the end of the long groove 331, causing the photovoltaic panel 1 and the bracket 2 to shake, thereby affecting the connection between the photovoltaic panel 1 and the bracket 2.

[0046] In another embodiment of the present invention, a support member for supporting the photovoltaic panel 1 is installed on the carrier plate 33 .

[0047] The support member includes a first support rod 333, a first telescopic rod 334, a second support rod 335 and a second telescopic rod 336. The lower ends of the first telescopic rod 334 and the second telescopic rod 336 are fixedly connected to the supporting plate 33. The first support rod 333 is installed on the upper end of the first telescopic rod 334, and the second support rod 335 is installed on the upper end of the second telescopic rod 336. The first telescopic rod 334 and the second telescopic rod 336 are both threadedly connected with locking screws.

[0048] The first support rod 333 and the second support rod 335 are both arranged along the length direction of the supporting plate 33, and the first support rod 333 is provided with a triangular groove along its own length direction to match the corner position of the photovoltaic panel 1. The cross-section of the second support rod 335 is triangular, and the second support rod 335 is arranged higher than the first support rod 333.

[0049] Specifically, after the connection between each bracket 2 and the bearing plate 33 is completed, that is, each bracket 2 is stuck in the long groove 331, the length of the first telescopic rod 334 and the second telescopic rod 336 is adjusted, and the first telescopic rod 334 and the second telescopic rod 336 are locked in the adjusted state by the locking screw, so that the first support rod 333 and the second support rod 335 can respectively support Figure 2 The left and right sides of the photovoltaic panel 1 in the view further enhance the restrictions on the photovoltaic panel 1 and the bracket 2 on the supporting plate 33.

[0050] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
