Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module supports, and in particular to a distributed photovoltaic power station group control and group modulation control structure. Background Art

[0002] A photovoltaic power station is an electric power system that converts light energy into electrical energy through solar photovoltaic modules and realizes grid-connected power generation through electrical equipment. At present, since various cables can be centrally arranged in the supporting cabinet, the cables can be planned and organized in an orderly manner to reduce the risk of cable failure. In order to achieve waterproof and dustproof effects and protect the safety of the photovoltaic modules and the entire power generation system, the photovoltaic modules used in photovoltaic power stations are usually directly fixed in the supporting cabinet for use. However, when inspecting the photovoltaic modules, it is necessary to manually cut off the power first and then remove the photovoltaic modules from the supporting cabinet. If the power is forgotten to be cut off, it may endanger the safety of the operator. In addition, during dismantling, the operator may need to use climbing equipment to reach the location of the corresponding photovoltaic module, which limits the efficiency of dismantling to a certain extent, making the dismantling work difficult. In view of this, the present invention is proposed. Summary of the Invention

[0020] Compared with the existing technology, the present invention provides a distributed photovoltaic power station group control and group modulation control structure, which has the following beneficial effects:

[0021] 1. The group control and group modulation control structure of the distributed photovoltaic power station forms a support structure for the photovoltaic module through a support cabinet and a support seat. The control support seat drives the photovoltaic module to move downward. When the support seat moves downward, the plug will be removed from the second circuit board first. When the auxiliary box moves to the bottom of the support cabinet, it will touch the main switch on the first circuit board, thereby turning off the main switch, thereby completing the closure of each circuit in the support cabinet. At this time, the operator can carry out maintenance work with confidence to avoid electric shock.

[0022] 2. The distributed photovoltaic power station group control and group modulation control structure, when the support seat moves downward, the small gear will engage with the tooth block on the T-block during the movement, so that the threaded rod rotates and drives the slide to move. When the auxiliary box moves, the plug can fall off the second circuit board. At this time, the auxiliary box can start to move downward, thereby facilitating subsequent maintenance operations. After the maintenance is completed, the support seat rises to a specific position, and the plug will automatically extend and connect to the second circuit board, so that it can continue to be used.

[0023] 3. The distributed photovoltaic power station group control and group modulation control structure has a main switch that can rotate on the first circuit board. In the initial state, the main switch is tilted and protruded at the lower end on the first circuit board. The pressure roller presses the lower end of the main switch when it moves downward to turn off the main switch. At this time, the operator can operate with confidence. When the support seat rises after the maintenance is completed, the pressure roller moves upward with the support seat, so that it will contact the main switch again and push the main switch to rotate, so that it rotates to the same state as the initial state, and it can work normally at this time.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0037] Example 1:

[0038] Reference Figures 1-10 A distributed photovoltaic power station group control and group modulation control structure includes a support cabinet 1, and also includes: a support base 2 slidably arranged in the support cabinet 1, and a plurality of photovoltaic modules 201 are provided on the support base 2; a hollow tube 303 is slidably arranged on the support base 2, and a slider 305 is provided at one end of the hollow tube 303 outside the support base 2; an auxiliary box 304 is also slidably arranged on the support base 2, and the slider 305 is slidably arranged in the auxiliary box 304, and a plug 309 is provided on the outer wall of the auxiliary box 304; a first circuit board 109 and a second circuit board 110 are fixedly connected to the inner wall of the support cabinet 1, the plug 309 is plugged into the first circuit board 109, and a main switch 111 is provided on the first circuit board 109; a baffle 108 is also fixedly connected to the support cabinet 1, and the baffle 108 is against the top outer wall of the auxiliary box 304.

[0039] In this embodiment, during installation, the support base 2 is first installed in the support cabinet 1, and then the photovoltaic module 201 is installed on the support base 2. The support cabinet 1 and the support base 2 form a support structure for the photovoltaic module 201, thereby completing the support of the photovoltaic module 201. When the photovoltaic module 201 needs to be repaired, the support base 2 is controlled to move downward, thereby driving the photovoltaic module 201 to move downward. After the support base 2 moves downward, the hollow tube 303 is controlled to move in the support base 2, thereby driving the slider 305 and the auxiliary box 304 to move, which will first make the plug 309 on the auxiliary box 304 move out from the second circuit board 110, and while the support base 2 moves downward, it will first drive the slider 30 5 moves downward. When the slider 305 moves to the bottom of the auxiliary box 304, it will start to drive the auxiliary box 304 to move downward. When the auxiliary box 304 moves to the bottom of the supporting cabinet 1, it will touch the main switch 111 on the first circuit board 109, thereby turning off the main switch 111, thereby completing the closure of various circuits in the supporting cabinet 1. At this time, the operator can perform maintenance work with confidence to avoid electric shock. At this time, the photovoltaic module 201 has moved to the bottom of the supporting cabinet 1, and the operator can perform maintenance operations more conveniently, which can improve the efficiency of dismantling and maintenance, reduce the difficulty of maintenance, facilitate group control and group dispatching, reduce management difficulty, and make management more convenient.

[0040] It should be noted that a wiring harness 203 is provided on the photovoltaic module 201, and a connector 202 is also provided on the photovoltaic module 201. The connector 202 can concentrate the wiring harness 203 on the photovoltaic module 201, so that the wiring harness 203 is placed in the support seat 2, passes through the hollow tube 303 and the slider 305 and is connected to the plug 309 for easy use.

[0041] Example 2: Reference Figures 1-10 A distributed photovoltaic power station group control and group modulation control structure includes a support cabinet 1, and also includes: a support base 2 slidably arranged in the support cabinet 1, and a plurality of photovoltaic modules 201 are provided on the support base 2; a hollow tube 303 is slidably arranged on the support base 2, and a slider 305 is provided at one end of the hollow tube 303 outside the support base 2; an auxiliary box 304 is also slidably arranged on the support base 2, and the slider 305 is slidably arranged in the auxiliary box 304, and a plug 309 is provided on the outer wall of the auxiliary box 304; a first circuit board 109 and a second circuit board 110 are fixedly connected to the inner wall of the support cabinet 1, the plug 309 is plugged into the first circuit board 109, and a main switch 111 is provided on the second circuit board 110; a baffle 108 is also fixedly connected to the support cabinet 1, and the baffle 108 is against the top outer wall of the auxiliary box 304.

[0042] Reference Figure 6-Figure 9The support base 2 is provided with a groove 206 , in which a threaded rod 3 is rotatably connected, and a slide 301 is threadedly connected to the threaded rod 3 , and a hollow tube 303 is fixedly connected to the outer wall of the slide 301 .

[0043] Reference Figure 6-Figure 9 A long slot 306 is provided on the auxiliary box 304, and the hollow tube 303 is slidably connected in the long slot 306. A first limiting rod 307 is fixedly connected in the auxiliary box 304, and the slider 305 is slidably set on the first limiting rod 307. A first spring 308 is provided between the top of the slider 305 and the top inner wall of the auxiliary box 304 and between the slider 305 and the bottom inner wall of the auxiliary box 304. The two first springs 308 are both sleeved on the outer wall of the first limiting rod 307.

[0044] In this embodiment, during maintenance, the support seat 2 drives the photovoltaic module 201 to move downward, and at the same time drives the slide plate 301 and the hollow tube 303 to move, thereby driving the slider 305 to move in the auxiliary box 304. After the slider 305 moves a certain distance, it will drive the plug 309 on the auxiliary box 304 to move out from the first circuit board 109. At this time, the support seat 2 and the auxiliary box 304 can move downward synchronously, thereby moving to the bottom of the support cabinet 1 for maintenance operations, thereby facilitating the operation of maintenance personnel.

[0045] Reference Figure 9 A pinion 302 is provided at one end of the threaded rod 3 placed outside the support seat 2, a support block 4 is fixedly connected to the inner wall of the support cabinet 1, a T-block 403 is slidably connected to the support block 4, and a tooth block 404 meshing with the pinion 302 is provided on the outer wall of the T-block 403.

[0046] Reference Figure 8 A T-shaped slot 401 is provided on the support block 4, and a T-shaped block 403 is slidably arranged in the T-shaped slot 401. The inner wall of the T-shaped slot 401 is fixedly connected with a second limiting rod 402. The T-shaped block 403 is slidably arranged on the second limiting rod 402. A second spring 405 is provided between the T-shaped block 403 and the inner wall of the T-shaped slot 401, and the second spring 405 is sleeved on the second limiting rod 402.

[0047] In this embodiment, when the support seat 2 moves downward, the threaded rod 3 and the pinion 302 will be driven to move downward synchronously. During the movement, the pinion 302 will engage with the tooth block 404 on the T-block 403, thereby driving the pinion 302 to rotate, so that the pinion 302 drives the threaded rod 3 to rotate, and the threaded rod 3 will drive the slide 301 threadedly connected to it to move, so that the slide 301 drives the slider 305 and the auxiliary box 304 to move through the hollow tube 303. When the auxiliary box 304 moves, the plug 309 can fall off the second circuit board 110. At this time, the auxiliary box 304 can start to move downward, thereby facilitating subsequent maintenance operations.

[0048] It should be noted here that, first, in the initial state, the T-block 403 is located at the bottom of the support block 4. When the pinion 302 engages with the tooth block 404 on the T-block 403, the pinion 302 will not cause the T-block 403 to move. Therefore, the tooth block 404 can stably drive the pinion 302 to rotate, thereby stably driving the auxiliary box 304 to move, so that the plug 309 is no longer connected to the second circuit board 110; second, when the support base 2 moves downward, the slider 305 will be driven downward through the hollow tube 303. Since the plug 309 is still plugged into the second circuit board 110 at this time, the slider 305 will first move downward in the auxiliary box 304. When the pinion 302 engages with the tooth block 404, so that the plug 309 is no longer connected to the second circuit board 110, the slider 305 that has moved to the bottom of the auxiliary box 304 will synchronously drive the auxiliary box 304 as a whole to move downward, thereby performing subsequent operations.

[0049] When the cam 311 is in the closed position, the cam 311 is in the closed position, and the cam 311 is in the closed position, so that the cam 311 is in the closed position.

[0050] Example 3: Reference Figures 1-10A distributed photovoltaic power station group control and group modulation control structure includes a support cabinet 1, and also includes: a support base 2 slidably arranged in the support cabinet 1, and a plurality of photovoltaic modules 201 are provided on the support base 2; a hollow tube 303 is slidably arranged on the support base 2, and a slider 305 is provided at one end of the hollow tube 303 outside the support base 2; an auxiliary box 304 is also slidably arranged on the support base 2, and the slider 305 is slidably arranged in the auxiliary box 304, and a plug 309 is provided on the outer wall of the auxiliary box 304; a first circuit board 109 and a second circuit board 110 are fixedly connected to the inner wall of the support cabinet 1, the plug 309 is plugged into the first circuit board 109, and a main switch 111 is provided on the second circuit board 110; a baffle 108 is also fixedly connected to the support cabinet 1, and the baffle 108 is against the top outer wall of the auxiliary box 304.

[0051] Reference Figure 10 The support seat 2 is provided with an arc groove 5 and a guide groove 501. A rotating shaft 502 is rotatably connected in the arc groove 5. A pressing block 503 that cooperates with the T-block 403 is fixedly connected to the rotating shaft 502. A slope 504 is provided on the pressing block 503.

[0052] Reference Figure 10 A torsion spring 505 is provided between the pressure block 503 and the inner wall of the arc groove 5. The torsion spring 505 is sleeved on the outer wall of the rotating shaft 502. A stopper 506 is slidably connected in the guide groove 501. A third spring 507 is provided between the stopper 506 and the inner wall of the guide groove 501.

[0053] In this embodiment, a pressure block 503 is also provided. When the support seat 2 moves downward, the pressure block 503 will contact the top of the T-block 403. Since the T-block 403 is at the bottom of the T-slot 401 at this time, it will not move downward any further. Therefore, when the pressure block 503 contacts the T-block 403, it will rotate, causing the pressure block 503 to rotate upward. At this time, the support seat 2 will drive the pressure block 503 to continue to move downward. When the pressure block 503 moves to the bottom of the T-block 403, the torsion spring 505 will automatically reset the pressure block 503 for subsequent use. After the support seat 2 drives the photovoltaic module 201 to move downward, the maintenance operation can be started.

[0054] It should be noted that the bottom of the pressing block 503 is provided with an inclined surface 504, so that the pressing block 503 can rotate better after contacting the T-block 403, and there is no obstruction above the pressing block 503, so there is no obstruction when the pressing block 503 rotates upward.

[0055] When the maintenance operation is completed, the support seat 2 is controlled to move upward, thereby driving the photovoltaic module 201 to move upward. When the pressing block 503 moves to abut against the bottom outer wall of the T-block 403, the stopper 506 is provided to block it. Therefore, the pressing block 503 will first push the T-block 403 to move upward, and at this time the pinion 302 is not engaged with the tooth block 404. When the T-block 403 moves upward to the limit position in the T-slot 401, the T-block 403 will not move upward again. At this time, the support seat 2 is still moving continuously. Therefore, the pressing block 503 will press the stopper 506 downward, thereby pushing the stopper 506 into the guide groove 501. At this time, the pressing block 503 will start to rotate downward, so that the pressing block 503 gradually starts to move above the T-block 403. When the auxiliary box 304 connected to the support seat 2 is pressed against the baffle 108, the position of the auxiliary box 304 is fixed, so that the position of the plug 309 and the second circuit board 110 are fixed. After the pressure block 503 moves to above the T-block 403, the T-block 403 is automatically reset under the action of the second spring 405, and the support seat 2 is still moving upward. Therefore, the tooth block 404 can be engaged with the pinion 302, so that the pinion 302 drives the threaded rod 3 to rotate, thereby driving the slide plate 301 threadedly connected thereto to move, thereby driving the auxiliary box 304 to move to the side close to the second circuit board 110 through the hollow tube 303 and the slider 305, so that the plug 309 is inserted into the second circuit board 110, so that the photovoltaic module 201 can be used normally.

[0056] It should be noted that the slider 305 is movable in the auxiliary box 304 . Therefore, when the auxiliary box 304 abuts against the baffle 108 , the support base 2 can also move a certain distance without becoming stuck.

[0057] A second limiting rod 402 is provided in the T-slot 401 to enable the T-block 403 to move more stably, and a second spring 405 is provided to enable the T-block 403 to automatically reset.

[0058] Reference Figure 8 and Figure 3 A connecting seat 310 is provided on the outer wall of the auxiliary box 304 , and a pressure roller 311 that cooperates with the main switch 111 is provided on the connecting seat 310 .

[0059] When in use, the main switch 111 can be rotated on the first circuit board 109. In the initial state, the main switch 111 is tilted and protruding at the lower end on the first circuit board 109. Therefore, the pressure roller 311 presses the lower end of the main switch 111 when it moves downward, thereby rotating it on the first circuit board 109 to turn off the main switch 111. At this time, the operator can operate with confidence. At this time, the pressure roller 311 also moves to the bottom of the main switch 111, and the main switch 111 is tilted and protruding at the upper end on the first circuit board 109. When the maintenance is completed, the support base 2 rises, and the pressure roller 311 moves upward with the support base 2, so that it will contact the main switch 111 again, thereby pushing the main switch 111 to rotate again, so that it rotates to the same state as the initial state, so that the support cabinet 1 can work normally. For details, refer to Figure 3 A notch is also provided on the first circuit board 109 so that the plug 309 will not come into contact with the first circuit board 109 after being moved down.

[0060] Example 4: Reference Figures 1-10 A distributed photovoltaic power station group control and group modulation control structure is basically the same as the first embodiment. Furthermore, a support box 6 is fixedly connected to the bottom outer wall of the support base 2, and a plug plate 602 is slidably connected to the support box 6. An adjustment rod 601 rotatably connected to the plug plate 602 is threadedly connected to the support box 6. A fixing bar 101 is provided on the inner wall of the support cabinet 1, and a slot 102 corresponding to the plug plate 602 is provided on the fixing bar 101.

[0061] In this embodiment, by rotating the adjusting rod 601, since the adjusting rod 601 is threadedly connected to the support box 6, the adjusting rod 601 can start to move, and drive the plug plate 602 to move, and make it inserted into the slot 102 on the fixing bar 101, thereby further supporting the support base 2 to prevent it from falling off. When the support base 2 needs to be moved down, the adjusting rod 601 is rotated in the opposite direction to disengage the plug plate 602 from the slot 102. Specifically, the adjusting rod 601 is a screw.

[0062] Reference Figure 1-Figure 5 A screw rod 105 is rotatably connected inside the support cabinet 1, and a guide rail 103 and a guide rod 106 are fixedly connected inside the support cabinet 1. A mounting seat 204 and a guide block 205 are provided on the outer wall of the support seat 2. There are two mounting seats 204, one of which is threadedly connected to the screw rod 105, and the other mounting seat 204 is slidingly connected to the guide rod 106. The guide block 205 is slidably connected in the guide rail 103. A cover plate 104 is also provided in the support cabinet 1, and a gear set 107 is provided on the outer wall of the screw rod 105. The cover plate 104 is provided with a driving member 112 for driving the gear set 107 to rotate.

[0063] In this embodiment, by starting the driving member 112, the gear set 107 can be rotated. The gear set 107 is specifically composed of a plurality of mutually meshing rotating gears. When the gear set 107 rotates, it can drive the screw rod 105 to rotate. When the screw rod 105 is threadedly connected to the mounting base 204, it can drive the movement of the support base 2, and the forward and reverse rotation of the screw rod 105 can be used to control the rise or fall of the support base 2. The provided guide rod 106 can guide the movement of the support base 2, making its movement more stable.
