The cabinet door 2 is mounted on both positioning shafts 3. A limiting block 4 is provided on the outer wall of each of the two positioning shafts 3. Two arc-shaped blocks 5 are provided in the positioning grooves 6 along the rotation direction of the positioning shaft 3. The two arc-shaped blocks 5 are used to position the limiting blocks 4.

[0034] Specifically, the photovoltaic (PV) cabinet is a crucial piece of equipment in a photovoltaic power station. It converts the direct current (DC) generated by the photovoltaic power generation system into alternating current (AC) and connects it to the power grid. The cabinet body 1 is the outer shell of the PV cabinet. A positioning groove 6 is formed at both the top and bottom of the cabinet body 1. A positioning shaft 3 is rotatably mounted in each of the two positioning grooves 6. A cabinet door 2 is mounted on both positioning shafts 3, and a switch is installed on the door 2 to open and close it. A square groove 7 is formed on each of the two positioning shafts 3. A limiting block 4 is slidably installed in each of the two square grooves 7. The two limiting blocks 4 and their corresponding inner walls of the square grooves 7 are connected by a third elastic element 8. An arc-shaped groove 9 is formed in each of the two positioning grooves 6. An arc-shaped block 5 is slidably installed in each of the two arc-shaped grooves 9. The two arc-shaped blocks 5 and their corresponding inner walls of the arc-shaped grooves 9 are connected by a first elastic element 10. Figure 6As shown, the first elastic member 10 is arranged in the rotation direction of the positioning shaft 3; the abutting portions of the two arc-shaped blocks 5 and the limiting block 4 are both in a slope shape, when the worker needs to open the cabinet door 2, the worker opens the cabinet door 2, the cabinet door 2 drives the positioning shaft 3 to rotate in the positioning groove 6, the positioning shaft 3 drives the limiting block 4 to rotate, and those skilled in the art can know that, in the rotation direction of the positioning shaft 3, a plurality of same arc-shaped grooves 9, arc-shaped blocks 5 and first elastic members 10 can be arranged in the positioning groove 6, when the positioning shaft 3 drives the limiting block 4 to rotate to the position abutting against the arc-shaped block 5, because the abutting portions of the two arc-shaped blocks 5 and the limiting block 4 are both in a slope shape, the abutting portions of the limiting block 4 and the arc-shaped block 5 can be wedge-shaped matched, the limiting block 4 is gradually slid into the square groove 7 under the pushing action of the arc-shaped block 5, the limiting block 4 extrudes the third elastic member 8 (the third elastic member 8 is an element capable of elastic return, preferably a spring) to make the third elastic member 8 in a compressed state, and the limiting block 4 is located in the square groove 7, when the limiting block 4 and the arc-shaped block 5 are separated from each other, under the rebounding action of the third elastic member 8, the third elastic member 8 drives the limiting block 4 to slide out of the square groove 7, at the same time, when the limiting block 4 and the arc-shaped block 5 abut against each other and rotate, the limiting block 4 drives the arc-shaped block 5 to rotate in the arc-shaped groove 9, the arc-shaped block 5 extrudes the first elastic member 10 (the first elastic member 10 is an element capable of elastic return, preferably a spring) to make the first elastic member 10 in a compressed state, when the limiting block 4 and the arc-shaped block 5 are separated from each other, under the rebounding action of the first elastic member 10, the first elastic member 10 drives the arc-shaped block 5 to slide to abut against the inner wall of the arc-shaped groove 9, so that the arc-shaped block 5 positions the limiting block 4, under the limiting action of the limiting block 4 and the arc-shaped block 5, the positioning shaft 3 and the cabinet door 2 cannot be closed, preventing the automatic closing of the cabinet door 2 from affecting the maintenance of the worker.

[0035] The existing technology has the following deficiencies: when the cabinet door 2 of the photovoltaic cabinet is opened, because the cabinet door 2 has a certain rotation flexibility, when the worker opens the cabinet door 2 to detect or maintain the inside of the photovoltaic cabinet, the cabinet door 2 needs to be kept open, and because of the rotation flexibility of the cabinet door 2, the cabinet door 2 will reciprocatingly swing (that is, the cabinet door 2 will be opened and closed alternately), which affects the maintenance work of the worker, at this time, the worker needs to use other objects to block the cabinet door 2, thereby affecting the maintenance efficiency of the worker.

[0036] The embodiment has the beneficial effect that when the worker needs to open the cabinet door 2 to maintain the internal structure of the cabinet 1, the worker opens the cabinet door 2, the cabinet door 2 drives the positioning shaft 3 to rotate, the positioning shaft 3 drives the limiting block 4 to rotate, the arc-shaped block 5 is used for positioning the limiting block 4, the arc-shaped block 5 is used for positioning the limiting block 4 and the positioning shaft 3, the positioning shaft 3 is used for positioning the cabinet door 2, and the automatic closing of the cabinet door 2 is prevented from affecting the maintenance work of the worker.

[0037] In another embodiment of the utility model, the cabinet 1 is symmetrically provided with two slide rails 11 in the middle part, two slide rails 11 are provided with a partition plate 12 which is slidably connected with the slide rails 11, and the slide connection part of the partition plate 12 and the slide rail 11 is of U-shaped structure; the side wall of the cabinet 1 is uniformly provided with a plurality of positioning holes 13; the two ends of the partition plate 12 are each provided with a U-shaped groove 14, the U-shaped groove 14 is slidably provided with a connecting plate 15, and the connecting plate 15 is uniformly provided with a plurality of positioning round rods 16; each positioning round rod 16 penetrates the U-shaped groove 14 and is inserted into the corresponding positioning hole 13; the inner wall between the two connecting plates 15 and the U-shaped groove 14 is connected by a plurality of second elastic members 17; the bottom end of each U-shaped groove 14 is provided with a through groove 18, and the bottom end of each connecting plate 15 is provided with a push plate 19, and the two push plates 19 are slidably arranged in the through groove 18.

In the embodiment, when it is necessary to adjust the position of the partition plate 12 on the slide rail 11, the workers use tools to push the two push plates 19 to slide towards each other at the same time (that is, the two push plates 19 slide towards the middle part of the partition plate 12 at the same time), the two push plates 19 drive the connecting plates 15 to slide into the U-shaped grooves 14 at the same time, the two connecting plates 15 drive the positioning round rods 16 to slide out of the positioning holes 13 at the same time, so that the positioning round rods 16 and the positioning holes 13 no longer position the partition plate 12, and at the same time, the connecting plates 15 extrude the second elastic members 17 (the second elastic members 17 are original members that can be stretched and reset, and are preferably springs), so that the second elastic members 17 are in a compressed state. The workers push the partition plate 12 to slide on the slide rail 11 until the partition plate 12 slides to a suitable position (that is, the partition plate 12 slides to a suitable position for dividing the cabinet 1 into regions, so that the partition plate 12 divides the cabinet 1 into suitable regions), and when the partition plate 12 slides to a suitable position on the slide rail 11, the workers release the pushing force on the push plates 19. Under the rebounding action of the second elastic members 17, the second elastic members 17 push the connecting plates 15 and the positioning round rods 16 to move away from each other, so that the positioning round rods 16 are inserted into the positioning holes 13, so that the positioning round rods 16 and the positioning holes 13 position the partition plate 12, so that the partition plate 12 can be appropriately divided into regions in the cabinet 1, and it is not necessary to adjust the position of the partition plate 12 by adjusting the threaded rod 20. The adjustment of the position of the partition plate 12 in the embodiment is more convenient.

[0039] The utility model provides still another embodiment provided by the utility model discloses a kind of auxiliary mechanism, which is arranged on the top of the partition plate 12, and the auxiliary mechanism includes L-shaped plate 21, two L-shaped plates 21 are symmetrically arranged on the top of the partition plate 12, the vertical section of the two L-shaped plates 21 (i.e. the part perpendicular to the partition plate 12) is connected with the partition plate 12, a groove 22 is formed on the horizontal section of the two L-shaped plates 21 (i.e. the part parallel to the partition plate 12), a straight plate 23 is slidably installed in each of the two grooves 22, a plurality of auxiliary round rods 24 are uniformly arranged on the two straight plates 23, a abutting groove 29 is formed at the bottom of each of the two straight plates 23, each of the auxiliary round rods 24 is inserted into the positioning hole 13, a through groove 25 is formed at the bottom of each of the two grooves 22, a driven plate 26 is slidably installed on the sidewall of each of the two through grooves 25, a pushing groove 27 is formed on the two driven plates 26, the bottom of each of the two driven plates 26 abuts against the top of the partition plate 12, a transmission plate 28 is rotatably installed in each of the two through grooves 25 through an auxiliary shaft, one end of the transmission plate 28 abuts against the abutting groove 29, the other end of the transmission plate 28 abuts against the pushing groove 27, and each of the two straight plates 23 and the inner wall of the corresponding groove 22 is connected by a plurality of fourth elastic members 30 uniformly arranged therebetween. Under the abutting action of the transmission plate 28 on the abutting groove 29, the fourth elastic members 30 are in a compressed state.
