[0021] The outdoor safety protection type low-voltage distribution cabinet of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0022] 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. Example

[0023] This embodiment discloses a low-voltage power distribution cabinet for outdoor use. The power distribution cabinet body 1 can be cooled by setting the heat dissipation holes 3. Figures 1-8 It mainly includes a distribution cabinet body 1 and a switch door 2. The switch door 2 is installed on the front side of the distribution cabinet body 1. A number of heat dissipation holes 3 are opened at the lower ends of both sides of the distribution cabinet body 1. The two sides of the distribution cabinet body 1 are fixedly connected with mounting plates 4. The lower end of each mounting plate 4 is rotatably connected with a rain shield 5 that can prevent rainwater from entering the inside of the distribution cabinet body 1 through the heat dissipation holes 3. A buffer component 7 is installed between the rain shield 5 and the distribution cabinet body 1. A water storage tank 6 is installed on the upper end of each rain shield 5. The lower end of the distribution cabinet body 1 is equipped with multiple lifting mechanisms 9 that can adjust the height of the distribution cabinet body 1; Through the coordinated design of the mounting plate 4, the rain shield 5 and the buffer assembly 7, the opening and closing degree of the rain shield 5 can be adjusted as needed. When it rains outdoors, part of the rainwater will fall on the rain shield 5, which can then cause the rain shield 5 to rotate downward, making the opening and closing degree of the rain shield 5 smaller, thereby effectively preventing rainwater from entering the distribution cabinet body 1 through the heat dissipation holes 3; and through the ingenious design of the water storage tank 6, part of the rainwater can be stored in the water storage tank 6 when it rains. Due to the gravity of the rainwater, the rain shield 5 can be rotated downward again, thereby making the opening and closing degree of the rain shield 5 smaller, thereby better preventing rainwater from entering the distribution cabinet body 1 through the heat dissipation holes 3; through the setting of the lifting mechanism 9, when there is too much water on the ground, the height of the distribution cabinet body 1 can be appropriately adjusted as needed, thereby effectively preventing the accumulated water on the ground from entering the distribution cabinet body 1.

[0024] In this embodiment, referring to Figure 1 、 Figure 3 、 Figure 4 and Figure 6The buffer assembly 7 includes a mounting seat 701, a mounting shaft 702, a connecting frame 703 and a first spring 704. The mounting seat 701 is fixedly connected to the outer wall of the distribution cabinet body 1. The upper end of the mounting seat 701 is evenly spaced with several mounting shafts 702 in the circumferential direction. The mounting shaft 702 is sleeved with a connecting frame 703, and each mounting shaft 702 is sleeved with a first spring 704. The first spring 704 is located between the mounting seat 701 and the connecting frame 703. The end of the connecting frame 703 away from the mounting seat 701 is fixedly connected to the lower end of the rain shield 5; when it rains outdoors, rainwater will fall on the rain shield 5, thereby causing the rain shield 5 to rotate downward, and the rain shield 5 squeezes the connecting frame 703. The connecting frame 703 moves downward, causing the first spring 704 to compress, thereby reducing the opening and closing degree of the rain shield 5, thereby preventing rainwater from entering the distribution cabinet body 1 from the heat dissipation hole 3.

[0025] In this embodiment, referring to Figure 1 、 Figure 3 、 Figure 4 and Figure 6 The connecting frame 703 is rotatably connected to a number of first connecting rods 705 at evenly spaced intervals in the circumferential direction, and each first connecting rod 705 is located between two adjacent mounting shafts 702, and each first connecting rod 705 is rotatably connected to a second connecting rod 706 at one end away from the connecting frame 703, and the second connecting rod 706 is rotatably connected to the mounting seat 701 at one end away from the first connecting rod 705. Through the coordinated transmission of the first connecting rod 705 and the second connecting rod 706, the rain shield 5 can be made to rotate more smoothly. At the same time, the rigidity and strength of the transmission of the first connecting rod 705 and the second connecting rod 706 also help to resist impact and ensure the stable operation of the buffer assembly 7.

[0026] In this embodiment, referring to Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8, each lifting mechanism 9 includes a base 901, a mounting cylinder 902, a lifting column 903, a top plate 904, a notch 905, an ear seat 906, a rotating shaft 907, a gear 908 and a motor 909. The upper end of the base 901 is symmetrically fixedly connected to the mounting cylinder 902, and a lifting column 903 is slidably connected in each mounting cylinder 902. The upper end of the lifting column 903 is fixedly connected to the top plate 904, and the upper end of the base 901 is symmetrically fixedly connected to the ear seats 906 on both sides. The two ear seats 906 are rotatably connected to the rotating shaft 907 through bearings, and the rotating shaft 907 is driven by a motor 909 (a conventional waterproof cover is installed on the motor 909, which is not shown in the figure. Since the waterproof cover belongs to the existing conventional structure, it will not be described in detail). Gears 908 are symmetrically installed on both sides of the shaft 907, and teeth meshing with the gears 908 are integrally formed on the lifting column 903 in the vertical direction. A notch 905 is provided at the middle and upper end of one side of the mounting cylinder 902, and the gear 908 is meshed and connected with the teeth on the lifting column 903 through the notch 905. When there is too much water on the ground, the motor 909 is started, and the motor 909 drives the rotating shaft 907 to rotate, and the rotating shaft 907 drives the gear 908 to rotate, and the gear 908 meshes with the teeth on the lifting column 903, so that the lifting column 903 moves upward, and the lifting column 903 drives the top plate 904 to move upward, thereby causing the distribution cabinet body 1 to move upward, thereby effectively preventing the accumulated water from entering the distribution cabinet body 1 due to excessive water accumulation on the ground. Example

[0027] On the basis of the first embodiment, this embodiment discloses an outdoor safety protection type low voltage distribution cabinet. In this embodiment, referring to Figure 1 、 Figure 3 and Figure 4 A second spring 8 is fixedly connected between the two sides of each rain shield 5 and the distribution cabinet body 1. Through the setting of the second spring 8, the rain shield 5 can be buffered again, thereby making the buffering effect of the rain shield 5 better. Example

[0028] The same points as the above embodiment will not be described in detail, but the differences are as follows: The present embodiment discloses a safety protection type low-voltage distribution cabinet for outdoor use. In the present embodiment, the design of the water outlet 601 allows rainwater in the water storage tank 6 to flow out slowly. The design of the filter 11 allows rainwater to be filtered, effectively preventing impurities in the rainwater from clogging the water outlet 601 and affecting the water outlet effect of the water outlet 601. The filter 11 is tilted to allow impurities on the filter 11 to flow downward, reducing the clogging of the filter 11. The ingenious design of the pressing assembly 12 facilitates the installation and removal of the filter 11, thereby facilitating the regular cleaning and replacement of the filter 11. Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , a plurality of water outlet holes 601 are provided at the lower end of each water storage tank 6, a filter screen 11 is connected to one end of each water storage tank 6 through a groove, and the filter screen 11 is arranged at an angle, and a clamping assembly 12 is installed at the other end of the water storage tank 6 for clamping the filter screen 11; the clamping assembly 12 includes a clamping shaft 1201, an annular baffle 1202, a fourth spring 1203 and a clamping rod 1204, the clamping shaft 1201 is slidably connected to one end of the water storage tank 6 through a through hole, the lower end of the clamping shaft 1201 is fixedly connected to the annular baffle 1202, and the fourth spring 1203 is sleeved on the clamping shaft 1201, the fourth spring 1203 is located between the water storage tank 6 and the annular baffle 1202, and the upper end of the clamping shaft 1201 is fixedly connected to a clamping rod 1204 for clamping one end of the filter screen 11; During actual use, before rainwater enters the water tank 6, it can be filtered through the filter 11, and then the rainwater enters the water tank 6. Finally, some water will slowly flow out from the water outlet 601 to prevent the rainwater in the water tank 6 from rotating the rain shield 5 downward due to gravity when it is not raining, thereby affecting the heat dissipation of the heat dissipation holes 3; when the filter 11 needs to be disassembled, the clamping shaft 1201 is moved upward until the clamping shaft 1201 is no longer in contact with the filter 11. At this time, the clamping shaft 1201 is rotated until the clamping rod 1204 is parallel to the filter 11, and then the clamping shaft 1201 is released. Under the elastic force of the fourth spring 1203, the clamping shaft 1201 is reset. At this time, the filter 11 can be disassembled conveniently and quickly. Example

[0029] Based on the first embodiment, this embodiment discloses an outdoor safety protection type low voltage distribution cabinet, referring to Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 A buffer cylinder 910 is fixedly connected to the middle part of the upper end of each base 901, and the interior of each buffer cylinder 910 is fixedly connected to one end of the third spring 912, and the other end of the third spring 912 is fixedly connected to a buffer rod 911, and the upper end of the buffer rod 911 is fixedly connected to the lower end of the top plate 904; through the arrangement of the buffer cylinder 910, the third spring 912 and the buffer rod 911, when the lifting mechanism 9 is damaged, the distribution cabinet body 1 will fall sharply. At this time, through the cooperation of the buffer rod 911 and the third spring 912, the distribution cabinet body 1 can be buffered to a certain extent, thereby effectively improving the safety of the distribution cabinet body 1. Example

[0030] The same points as the above embodiment will not be described in detail, but the differences are as follows: This embodiment discloses a low-voltage power distribution cabinet for outdoor use. In this embodiment, a combination of moisture-proof composite layers 10 can form multiple moisture-proof barriers to effectively block the intrusion of moisture and ensure that the internal environment of the power distribution cabinet body 1 is dry and stable. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A moisture-proof composite layer 10 is installed between the top plate 904 and the distribution cabinet body 1; the moisture-proof composite layer 10 includes an epoxy resin moisture-proof layer 1001, a polyurethane moisture-proof layer 1002, a polyethylene moisture-proof film 1003 and a waterproof paint moisture-proof layer 1004. The epoxy resin moisture-proof layer 1001 is fixedly connected to the lower end of the distribution cabinet body 1, and the waterproof paint moisture-proof layer 1004 is fixedly connected to the upper end of the top plate 904. The polyurethane moisture-proof layer 1002 and the polyethylene moisture-proof film 1003 are installed in sequence from top to bottom between the epoxy resin moisture-proof layer 1001 and the waterproof paint moisture-proof layer 1004; The epoxy resin moisture barrier 1001 is a chemically synthesized material with extremely strong adhesion and chemical corrosion resistance. It can form a dense protective film to effectively block the intrusion of moisture. This characteristic makes the epoxy resin moisture barrier 1001 play a key role in the moisture-proof protection of the distribution cabinet body 1. It can prevent moisture from entering from the bottom of the distribution cabinet body 1 and keep the internal environment of the distribution cabinet body 1 dry. The polyurethane moisture-proof layer 1002 further enhances the moisture-proof performance of the distribution cabinet body 1. Polyurethane has excellent moisture-proof performance and can effectively prevent moisture penetration. The polyurethane moisture-proof layer 1002 can also increase the sealing performance of the distribution cabinet body 1 and prevent the intrusion of external moisture. The polyethylene moisture-proof membrane 1003 is made of high-quality high-density polyethylene virgin resin and has extremely low liquid permeability, forming an indestructible waterproof barrier. This design further improves the moisture-proof performance of the distribution cabinet body 1 and ensures the safe operation of the electrical components inside the distribution cabinet body 1; Waterproof coating has excellent waterproof performance and durability, and can form a tough waterproof layer to effectively block the intrusion of rain and moisture.

[0031] The working principle of the outdoor safety protection type low-voltage distribution cabinet of the present invention is as follows: when it rains outdoors, some rainwater will fall onto the rain shield 5, and the rain shield 5 will rotate downward. In the process of the rain shield 5 rotating downward, the second spring 8 is compressed, and the connecting frame 703 moves downward, so that the first spring 704 is compressed, and the first connecting rod 705 and the second connecting rod 706 rotate, thereby reducing the opening and closing degree of the rain shield 5. In addition, when it rains, some rainwater is stored in the water storage tank 6. Due to the gravity of the rainwater, the opening and closing degree of the rain shield 5 can be further reduced, thereby better preventing rainwater from entering the distribution cabinet body 1 through the heat dissipation holes 3. When it is not raining, due to the elastic force of the first spring 704 and the second spring 8, the rain shield 5 can be reset, thereby reducing the blocking of the heat dissipation holes 3, so that the heat in the distribution cabinet body 1 can be normally dissipated from the heat dissipation holes 3; When there is too much water on the ground, the motor 909 is controlled, and the motor 909 drives the rotating shaft 907 to rotate, and the rotating shaft 907 drives the gear 908 to rotate. The gear 908 engages with the teeth on the lifting column 903 to raise the lifting column 903, and then the height of the distribution cabinet body 1 can be appropriately adjusted, thereby effectively preventing the accumulated water on the ground from entering the interior of the distribution cabinet body 1 when there is too much water on the ground.
