Two groups of first telescopic frames 302 and second telescopic frames 303 are symmetrically arranged between the first support frame 301 and the second support frame 304. The first telescopic frames 302 and the second telescopic frames 303 are slidably connected, and a plurality of photovoltaic panels 401 are arranged in parallel between the two groups of first telescopic frames 302 and second telescopic frames 303. By rotating the photovoltaic panels 401 to a vertical state and contracting the first telescopic frames 302 and the second telescopic frames 303, the photovoltaic panels 401 are easy to be stored. By rotating the photovoltaic panels 401 to a horizontal state and adaptively extending the first telescopic frames 302 and the second telescopic frames 303, the photovoltaic panels 401 are easy to be exposed to sunlight. The surface of the second telescopic frame 303 is provided with a placing groove 320, through which the number of photovoltaic panels 401 between the two sets of first telescopic frames 302 and second telescopic frames 303 can be adjusted; A support base 501 is provided below the first support frame 301 and the second support frame 304, a limited telescopic rod 519 is provided between the two support frames 501, both ends of the limited telescopic rod 519 are fixedly connected to the two support frames 501, and casters 502 are symmetrically provided on the surface of the support frames 501.

By adjusting the telescopic length of the electric push rods 517 , the normal direction of the upper surface of the photovoltaic panel 401 is made close to the irradiation direction of sunlight.

The first support frame 301, the first telescopic frame 302, the second telescopic frame 303 and the second support frame 304 inside the storage box 201 are moved out of the storage box 201, and the length between the first telescopic frame 302 and the second telescopic frame 303 is adjusted to rotate the photovoltaic panel 401 from a vertical state to a state parallel to the first telescopic frame 302, so that the photovoltaic panel 401 can enter the solar energy collection state as soon as possible; Increase or decrease the number of photovoltaic panels 401 between the first support frame 301 and the second support frame 304 through the placement slot 320, or replace one or more photovoltaic panels 401 between the first support frame 301 and the second support frame 304; When the first support frame 301 and the second support frame 304 need to be moved, the two casters 502 inside the support seat 501 are rotated to rotate the wheel bodies of the casters 502 downward. When the first support frame 301 and the second support frame 304 do not need to be moved, the wheel bodies of the casters 502 are rotated upward to keep the first support frame 301 and the second support frame 304 stably placed. When the photovoltaic panel 401 is collecting solar energy, the efficiency of collecting solar energy by the photovoltaic panel 401 is improved by adjusting the height of the electric control push rod 517 .

[0033] It should be noted that the usage and working principles of the photovoltaic panel 401, inverter, energy storage battery, controller, combiner box and distribution cabinet are well known in the prior art and will not be described in detail here.

[0034] The upper surface of the first support frame 301 is symmetrically fixedly connected with the first connecting block 310, the bottom surface of the first connecting block 310 is fixedly connected with the bottom connecting block 312, the bottom connecting block 312 is fixedly connected to the first telescopic frame 302, the second support frame 304 and the second telescopic frame 303 are both fixedly connected, the surface of the first telescopic frame 302 is slidably connected with the bite slider 403, the surface of the photovoltaic panel 401 is fixedly connected with the protective frame 402, the bite slider 403 is symmetrically arranged on the surface of the protective frame 402, the bite slider 403 is rotatably connected to the protective frame 402 through the first bearing, and the bite slider 403 and the protective frame 402 are both slidably connected.

[0035] In an embodiment of the present invention, the first telescopic frame 302 is slidably connected to the inside of the engaging slider 403, so that the protective frame 402 between the two first telescopic frames 302 is slidably connected to the two first telescopic frames 302 through the two engaging sliders 403, and then the relative position between the protective frame 402 and the first telescopic frame 302 and the second telescopic frame 303 can be adjusted, which facilitates the rapid laying of the photovoltaic panel 401.

[0036] The second hook 405 is fixedly connected to the surface of the protection frame 402 , the first hook 404 is fixedly connected to the first groove opened on the surface of the protection frame 402 , and the first hook 404 is fixedly connected to the surface of the second support frame 304 .

[0037] In the embodiment of the present invention, during the process of laying the photovoltaic panel 401, the protective frame 402 closest to the surface of the second support frame 304 is first rotated to a position where the second hook 405 on the surface is slightly higher than the first hook 404 on the surface of the second support frame 304, so that the protective frame 402 closest to the surface of the second support frame 304 slides toward the first hook 404 on the surface of the second support frame 304, and the protective frame 402 closest to the surface of the second support frame 304 hooks the first hook 404 on the surface of the second support frame 304 through the second hook 405 on its surface. At this time, the protective frame 402 closest to the surface of the second support frame 304 is supported by two engaging sliders 403 on its surface and the first hook 404 on the surface of the second support frame 304 to maintain a horizontal position with the extension direction of the first telescopic frame 302; According to the above steps, the protective frame 402 between the second support frame 304 and the first support frame 301 is hooked and matched with the adjacent second hook 405 and the first hook 404, so as to quickly complete the deployment of the photovoltaic panel 401. After the first hook 404 and the second hook 405 are hooked, the adjacent protective frames 402 have a restraining force along the extending direction of the vertical first telescopic frame 302, thereby increasing the stability of the photovoltaic panel 401 during operation; In order to prevent the adjacent protection frames 402 from having too much force when they collide with each other, the arc surface of the second hook 405 can release the hooking between the corresponding second hook 405 and the first hook 404 when the force of the conflict between two adjacent protection frames 402 is too great.

[0038] The surface of the first connecting block 310 is hinged with the second connecting block 311, the bottom surface of the second connecting block 311 is fixedly connected with the first folding frame 305, the surface of the first folding frame 305 is provided with a first adjusting groove 319, the surface of the first support frame 301 is provided with a second adjusting groove 321, the surface of the first folding frame 305 is hinged with the third telescopic frame 306, the surface of the third telescopic frame 306 is slidably connected with the fourth telescopic frame 307, the interior of the second support frame 304 is symmetrically provided with extension rods 308, the extension rods 308 are slidably connected to the second support frame 304 through the first rectangular slide groove provided on the surface of the second support frame 304, the ends of the extension rods 308 are fixedly connected with connecting heads 309, and the interior of the connecting head 309 is fixedly connected with a plug block 314.

[0039] In the embodiment of the present invention, the second connecting block 311 is rotated around the first connecting block 310 until the extension direction of the first folding frame 305 is parallel to the extension direction of the first support frame 301, and the first adjustment slot 319 and the second adjustment slot 321 are aligned, and then the third telescopic frame 306 on the surface of the first folding frame 305 is rotated to make the extension direction of the third telescopic frame 306 perpendicular to the extension direction of the first folding frame 305, and the extension rod 308 is moved in a direction away from the inside of the second support frame 304 to align the plug block 314 inside the connector 309 with the corresponding fourth telescopic frame 307, and the fourth telescopic frame 307 on the surface of the third telescopic frame 306 is slid until The plug block 314 is inserted into the fourth telescopic frame 307 and the second threaded hole 521 on the surface of the plug block 314 is aligned with the first threaded hole 520 on the surface of the fourth telescopic frame 307. The bolts of corresponding specifications are threadedly connected with the second threaded hole 521 and the first threaded hole 520 at the same time. The length of the limiting telescopic rod 519 is kept unchanged by the locking mechanism of the limiting telescopic rod 519. At this time, the support frame composed of the first support frame 301, the first folding frame 305, the first telescopic frame 302, the second telescopic frame 303, the second support frame 304, the fourth telescopic frame 307 and the third telescopic frame 306 is kept fixed so that the photovoltaic panel 401 on the surface thereof maintains a stable working state; When the first folding frame 305, the third telescopic frame 306 and the fourth telescopic frame 307 are in the unfolded state, the protective frame 402 between the two first telescopic frames 302 is slid so that the two engaging sliders 403 on the surface of the protective frame 402 slide into the interior of the second adjustment groove 321, and the two engaging sliders 403 slide from the interior of the second adjustment groove 321 to the interior of the first adjustment groove 319 until the protective frame 402 moves in the first adjustment groove 319 to between one of the first telescopic frames 302 and the third telescopic frame 306. The two engaging slide blocks 403 on the surface of 402 slide from the inside of the first adjustment groove 319 to the corresponding third telescopic frame 306 and the surface of the first telescopic frame 302, thereby completing the transfer of the protection frame 402. When the plurality of protection frames 402 located between the first telescopic frame 302 and the third telescopic frame 306 are hooked with each other through the first hook body 404 and the corresponding second hook body 405, the two protection frames 402 located on the outside are supported only by the restraining force of a group of first hook bodies 404 and second hook bodies 405 along the extending direction perpendicular to the first telescopic frame 302. When storing the photovoltaic panels 401, the photovoltaic panels 401 can be rotated to a vertical state, and all the photovoltaic panels 401 can be transferred between the two first telescopic frames 302, by shrinking the third telescopic frame 306 and the fourth telescopic frame 307 to a shorter state, and by rotating the third telescopic frame 306 around the first folding frame 305 until the third telescopic frame 306 and the fourth telescopic frame 307 are stored inside the first adjustment groove 319.

[0040] The ends of the output shaft of the electric control push rod 517 are fixedly connected with the ball head rod 516, and the surface of the ball head rod 516 is provided with a ball socket 515, wherein two ball sockets 515 are fixedly connected to the first support frame 301, and the other two ball sockets 515 are fixedly connected to the connecting head 309 accordingly. The electric control push rod 517 below the first support frame 301 is installed on the surface of the corresponding support seat 501, and the bottom of the electric control push rod 517 below the connecting head 309 is fixedly connected with a support block 518, and the surface of the support block 518 is provided with a supporting telescopic rod 522, which is installed in a first reserved groove opened on the surface of the corresponding support seat 501, and the two ends of the supporting telescopic rod 522 are respectively fixedly connected to the support block 518 and the support seat 501.

[0041] In the embodiment of the present invention, when adjusting the angle of the photovoltaic panel 401, the height of the four electrically controlled push rods 517 can be adjusted so that the normal of the upper surface of the photovoltaic panel 401 is close to the irradiation angle of the sunlight, thereby improving the efficiency of the photovoltaic panel 401 in collecting solar energy. By supporting the extension and retraction of the telescopic rod 522, the electrically controlled push rod 517 on the support block 518 follows the extension rod 308 to drive the extension of the connecting head 309 and move.

[0042] The U-shaped part of the support seat 501 is fixedly connected with the first round rod 505, the surface of the caster 502 is provided with a rotating connection hole 503, the first round rod 505 is rotatably connected to the inside of the rotating connection hole 503 through a second bearing, the surface of the support seat 501 is symmetrically provided with support grooves 509, the surface of the support seat 501 is symmetrically fixedly connected with a round hole rectangular block 513, the inside of the round hole rectangular block 513 is slidably connected with a limiting rod 512, the limiting rod 512 is slidably connected to the support seat 501 through the support groove 509, the surface of the caster 502 is provided with two limiting holes 504, the support groove 509 is inserted into the inside of one of the limiting holes 504, and the surface of the support seat 501 is symmetrically fixedly connected with a positioning baffle 514.

[0043] In the embodiment of the present invention, when it is necessary to move the first support frame 301 and the second support frame 304, the handle 510 is pulled upward until the support seat 501 corresponding to the handle 510 leaves the ground to a suitable height. The upward movement of the handle 510 drives the two connecting rods 511 to rotate. The rotation of the connecting rod 511 causes the limiting rods 512 in the two circular hole rectangular blocks 513 to move toward each other until the limiting rods 512 leave the limiting holes 504 opened on the surface of the caster 502, so that the caster 502 rotates until the wheel body faces downward, so that the support seat 501 off the ground is lowered until the wheel body of the caster 502 is When the handle 510 contacts the ground, the handle 510 is moved in the direction close to the corresponding support seat 501 until the limit rod 512 is inserted into the inside of another limit hole 504. In the same way, the caster 502 on the surface of the other support seat 501 is rotated until the wheel body is facing downward. The first support frame 301, the second support frame 304 and the photovoltaic panels 401 therebetween are pushed to move by the caster 502. The setting of the positioning baffle 514 makes the maximum rotation angle of the caster 502 180 degrees, so that when the caster 502 is rotated to conflict with the positioning baffle 514, the limit rod 512 is aligned with the support slide groove 509.

[0044] The surface of the caster 502 is fixedly connected to a T-shaped hollow rod 508, the surface of the T-shaped hollow rod 508 is rotatably connected to a uncovered round box 506, the uncovered round box 506 is fixedly connected to the support seat 501 via a third bearing, a torsion spring 507 is arranged inside the uncovered round box 506, and the two ends of the torsion spring 507 are respectively fixedly connected to the uncovered round box 506 and the T-shaped hollow rod 508.

[0045] A handle 510 is disposed on the surface of the support seat 501 , and connecting rods 511 are symmetrically disposed on the surface of the handle 510 . One end of the connecting rod 511 away from the handle 510 is hinged to a corresponding limiting rod 512 .

[0046] In the embodiment of the present invention, before rotating the caster 502, the elastic potential energy of the torsion spring 507 is increased by rotating the uncovered round box 506, so that after the limiting rod 512 leaves the interior of the limiting hole 504, the caster 502 continues to contact the positioning baffle 514 under the action of the elastic potential energy of the torsion spring 507, or rotates 180 degrees and then tightly contacts the positioning baffle 514 again. This process allows the staff to directly rotate the caster 502 to the required position after lifting the corresponding support seat 501 upward through the handle 510, reducing the staff's action of adjusting the angle of the caster 502. In the process of lowering the handle 510 and lowering the support seat 501, the angle between the caster 502 and the ground is an acute angle. Therefore, the influence of the gravity of the handle 510 on the caster 502 will make the caster 502 contact more tightly with the positioning baffle 514, which is conducive to reinserting the limiting rod 512 into the corresponding limiting hole 504.
