Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and specifically to outdoor distribution cabinets. Background Art

[0002] A distribution cabinet (also called a distribution panel, distribution box, distribution cabinet, etc.) is an important device in the power system, mainly used for receiving, distributing, and controlling the flow of electric power. It is usually used in industrial, commercial buildings, residential areas, etc. to ensure the stable supply of electric power, ensure the safe operation of equipment, and provide necessary protection functions for the equipment. A distribution cabinet generally consists of multiple electrical components, such as circuit breakers, disconnectors, contactors, ammeters, voltmeters, etc.

[0003] In the patent application document with the publication number CN116581667A, an adaptive outdoor distribution cabinet is disclosed, which includes a cabinet body, multiple support columns, multiple rain shields, multiple first heat dissipation holes, two groups of offset plates, a rain storage trigger box, and an ejection mechanism. The multiple support columns are arranged at the lower end of the cabinet body, and the multiple rain shields and first heat dissipation holes are fixedly arranged on both sides of the cabinet body. Each first heat dissipation hole is correspondingly arranged at the lower end of a rain shield. The two groups of offset plates are respectively movably arranged on the inner side of the cabinet body where the rain shields are installed through guide rails, and the offset plates are provided with multiple first offset holes corresponding to the first heat dissipation holes one by one. When it is sunny, the first heat dissipation holes can be aligned with the first offset holes to achieve effective heat dissipation of the cabinet body; when it is rainy, the ejection mechanism is pressed down by the rain storage trigger box, and rainwater can be temporarily stored in the rain storage trigger box. The greater the rainfall, the greater the storage capacity in the rain storage trigger box, and the greater the degree to which the rain storage trigger box presses down the pressing rod, the smaller the coincidence degree between the first heat dissipation holes and the first offset holes, so that the size of the first heat dissipation holes can be automatically adjusted according to the amount of rainfall to prevent rainwater from entering the interior of the cabinet body and automatically adjust the waterproof ability.

[0004] There are still the following problems in this solution. Although it can prevent rainwater from entering the interior of the cabinet body, the premise of rain prevention is that the cabinet door is closed. When line emergency repair is required on a rainy day and it is necessary to operate inside the distribution cabinet, only by opening the cabinet door can the operation be carried out. Rainwater will still sweep into the interior of the cabinet body after the cabinet door is opened, which results in inevitable intrusion of rainwater when operating the distribution cabinet on a rainy day, and is not conducive to the operation and maintenance of the distribution cabinet on a rainy day. Summary of the Invention

[0005] The present invention provides an outdoor distribution cabinet, aiming to solve the problem that rainwater inevitably intrudes when operating the distribution cabinet on a rainy day in the related art, which is not conducive to the operation and maintenance of the distribution cabinet on a rainy day.

[0006] The outdoor distribution cabinet of the present invention includes a cabinet body, a cabinet door is arranged on the cabinet body, and an adjustment window is arranged on the cabinet door for adjusting the electrical components inside the cabinet body. A shielding mechanism is arranged inside the adjustment window, which can block rainwater when adjusting the electrical components.

[0007] The adjustment window includes a frame body and a cover plate. The frame body is fixedly installed on the cabinet door, and the cover plate is rotatably assembled outside the frame body. A receiving groove is formed in the side wall of the frame body.

[0008] The shielding mechanism includes a horizontal shaft, a mounting ring, support rods and a waterproof cloth. The horizontal shaft is fixedly installed inside the receiving groove, and the horizontal shaft is coaxially arranged with the rotating shaft of the cover plate. The mounting ring is rotatably assembled outside the horizontal shaft. The support rods are fixedly installed on the mounting ring. There are multiple mounting rings and support rods, which are equidistantly distributed along the axial direction of the horizontal shaft. The two support rods located at both ends of the horizontal shaft are respectively arranged in the receiving groove and on the cover plate. The waterproof cloth is arranged between the multiple support rods.

[0009] The effect is that the electrical components in the cabinet can be directly adjusted through the frame body without opening the cabinet door. Through the mutual cooperation of the cover plate and the waterproof cloth, the upper and side parts of the frame body can be shielded, effectively preventing rainwater from being swept into the cabinet when the staff operates the electrical components, thereby improving the rainproof effect of the equipment.

[0010] Preferably, an opening is formed in the cabinet door, and the frame body is fixedly installed inside the opening.

[0011] Preferably, an insert strip adapted to the receiving groove is fixedly installed inside the cover plate. The support rod is fixed to the cover plate through the insert strip. A through hole communicating with the receiving groove is formed at the bottom of the frame body. The effect is that after the cover plate covers the outside of the frame body, the support rod and the waterproof cloth can be automatically pressed into the receiving groove through the insert strip to complete the storage of the waterproof cloth.

[0012] Preferably, a partition plate is fixedly installed inside the cabinet body. A storage cavity is formed between the top of the partition plate and the cabinet body, and a heat dissipation cavity is formed between the bottom of the partition plate and the cabinet body.

[0034] Refer to Figure 5 , a top cover 17 is fixedly installed on the top of the cabinet body 10. A transfer cavity 18 communicating with the storage cavity 13 is opened inside the top cover 17, and an inclined pipe 19 is fixedly installed inside the top cover 17 to communicate the transfer cavity 18 with the outside of the cabinet body 10, so that the hot air in the storage cavity 13 can be discharged to the outside of the cabinet body 10 through the transfer cavity 18 and the inclined pipe 19 to facilitate heat dissipation of the cabinet body 10.

[0035] Refer to Figure 6 and Figure 8, the adjustment window 20 includes a frame body 21 and a cover plate 22. The frame body 21 is fixedly installed in the opening, and the cover plate 22 is rotatably assembled outside the frame body 21, capable of blocking and closing the opening. By flipping the cover plate 22 upwards outside the frame body 21, the staff can directly extend the arm into the cabinet body 10 through the opening, and then operate the electrical components in the power distribution cabinet. Moreover, the cover plate 22 can block rainwater above the opening to prevent rainwater from entering the opening. For the convenience of observation, the cover plate 22 can be made of transparent material.

[0036] Reference Figure 8 , receiving grooves 211 are formed in the left and right opposite side walls of the frame body 21. Insertion strips 221 adapted to the receiving grooves 211 are fixedly installed inside the cover plate 22. The shielding mechanism 30 is arranged between the receiving grooves 211 and the insertion strips 221.

A positioning component 70 is arranged between the cover plate 22 and the cabinet door 11 for positioning the cover plate 22 after it is opened.

[0037] Reference Figure 6 And Figure 8 , the shielding mechanism 30 includes a horizontal shaft 31, a mounting ring 32, a support rod 33 and a waterproof cloth 34. The horizontal shaft 31 is fixedly installed inside the receiving groove 211, and the horizontal shaft 31 is coaxially arranged with the rotation axis of the cover plate 22. The mounting ring 32 is rotatably assembled outside the horizontal shaft 31. The support rod 33 is fixedly installed on the mounting ring 32. There are multiple mounting rings 32 and support rods 33, which are equidistantly distributed along the axial direction of the horizontal shaft 31. And the two support rods 33 located at both ends of the horizontal shaft 31 are respectively fixedly installed on the receiving groove 211 and the insertion strip 221. The waterproof cloth 34 is arranged between the multiple support rods 33. When the cover plate 22 is flipped upwards and opened from the frame body 21, the insertion strip 221 drives one of the support rods 33 at the end of the horizontal shaft 31 to rotate around the horizontal shaft 31, pulling the waterproof cloth 34, so that the mounting rings 32 on the multiple support rods 33 rotate successively, and then the waterproof cloth 34 is pulled out and unfolded from the receiving groove 211 to shield the side of the frame body 21, thereby preventing rainwater from being swept into the cabinet body 10 from the side and improving the rainproof effect of the equipment. When the cover plate 22 rotates close to the frame body 21, the insertion strip 221 presses the support rod 33 into the receiving groove 211. When the multiple support rods 33 enter the receiving groove 211, they automatically pull the waterproof cloth 34 to fold and enter the receiving groove 211 to complete the storage.

[0038] Reference Figure 1 And Figure 2, the locking mechanism 40 includes a positioning plate 41, a positioning buckle 42 and a plug rod 43. The positioning plate 41 is fixedly installed on the cabinet door 11, the positioning buckle 42 is fixedly installed on the cover plate 22, and the positioning plate 41 passes through the inside of the positioning buckle 42. An insertion hole 421 is formed inside the positioning buckle 42, and the plug rod 43 is inserted into the insertion hole 421, thereby blocking the positioning buckle 42 and preventing the positioning buckle 42 from detaching from the positioning plate 41, so that the cover plate 22 cannot be flipped open.

[0039] Reference Figure 3 , Figure 4 and Figure 7 , the mounting bracket 50 includes brackets 51, brackets 52, double-headed screws 53 and clamping plates 54. There are two brackets 51 which are symmetrically fixed on the partition plate 12, and vertical grooves 511 are formed in both brackets 51 along their height directions. The bracket 52 is arranged between the two brackets 51 and can slide up and down relative to the bracket 51 to support electrical components. There are two double-headed screws 53 which are both rotatably assembled in the bracket 52. The ends of the two double-headed screws 53 respectively pass through the vertical grooves 511 on the two brackets 51. There are two clamping plates 54 which are respectively located on the front and rear sides of the bracket 52. The two ends of the clamping plate 54 respectively extend to the sides of the two brackets 51, and the two double-headed screws 53 are both threadedly connected in the clamping plate 54. By sliding the double-headed screws 53 in the vertical grooves 511, the bracket 52 is lifted and lowered between the two brackets 51, and then the height of the bracket 52 can be adjusted according to the volume of the electrical component, so that the electrical component can be close to the opening, which is convenient for adjusting the electrical component through the adjustment window 20. By rotating the two double-headed screws 53, the clamping plate 54 is pushed to approach and closely adhere to the bracket 51, thereby restricting the movement of the double-headed screw 53 in the vertical groove 511 and fixing the height of the bracket 52.

[0040] Reference Figure 5 , the heat dissipation mechanism 60 includes a ventilation disc 61, a motor 62 and a heat dissipation fan 63. The ventilation disc 61 is rotatably assembled inside the installation groove 15, and a ventilation groove 611 adapted to the notch 16 is formed in the ventilation disc 61. The motor 62 and the heat dissipation fan 63 are both fixedly installed inside the heat dissipation cavity 14, and the output end of the motor 62 is fixed to the ventilation disc 61, and the ventilation disc 61 can be driven by the motor 62 to rotate, so that the ventilation groove 611 is aligned and communicated with the notch 16. Then, the heat dissipation fan 63 ventilates and dissipates heat inside the storage cavity 13 through the communication groove 121, the ventilation groove 611 and the notch 16. By rotating the ventilation disc 61 to misalign the ventilation groove 611 with the notch 16, the ventilation disc 61 can close the notch 16, thereby preventing rainwater from seeping into the cabinet body 10 from the bottom. A sealing ring is arranged inside the ventilation groove 611, which can improve the sealing performance between the ventilation disc 61 and the bottom wall of the cabinet body 10 after the ventilation groove 611 is misaligned with the notch 16, thereby improving the waterproof effect.

[0041] ReferenceFigure 1 , the positioning component 70 includes a first magnet 71 and a second magnet 72. The first magnet 71 is fixedly installed on the cabinet door 11, above the opening. The second magnet 72 is fixedly installed on the cover plate 22 and can be adsorbed with the first magnet 71 as the cover plate 22 rotates and opens, fixing the cover plate 22 to keep the opening open, thus facilitating the staff to adjust the electrical components.

[0042] Working principle: Pull out the insertion rod 43 to release the limit locking of the positioning buckle 42, and then turn up the cover plate 22 upward to make the second magnet 72 adsorbed with the first magnet 71 to fix the opened cover plate 22. The cover plate 22 can block the rainwater above the frame body 21 and above the opening. While the cover plate 22 is flipped and opened, the insertion strip 221 drives the support rod 33 at the end of the cross shaft 31 to rotate around the cross shaft 31, pulling the waterproof cloth 34, so that a plurality of support rods 33 rotate and rise successively, pulling out and unfolding the waterproof cloth 34 from the accommodation groove 211 to block the rainwater on the side of the frame body 21. The staff can extend their arms into the cabinet body 10 from the frame body 21 to operate the electrical components in the storage cavity 13.

[0043] In the present invention, after the cover plate 22 is opened, the electrical components in the cabinet body 10 can be directly adjusted and operated through the frame body 21 without opening the cabinet door 11. Moreover, through the mutual cooperation of the cover plate 22 and the waterproof cloth 34, the upper part and the side part of the frame body 21 can be shielded, effectively preventing rainwater from being swept into the cabinet body 10 when the staff operates the electrical components, thus improving the rainproof effect of the equipment and facilitating the staff to operate the electrical components in the cabinet body 10 on rainy days, improving the use effect of the power distribution cabinet outdoors; by adjusting the height of the bracket 52, the distance between it and the frame body 21 can be adjusted according to the size of the electrical components, thus facilitating the operation and adjustment of the electrical components through the adjustment window 20. Through the heat dissipation mechanism 60, the exchange of gas inside and outside the cabinet body 10 can be accelerated, thus improving the heat dissipation effect. Moreover, the heat dissipation mechanism 60 is located at the bottom of the cabinet body 10, which can prevent rainwater from entering the cabinet body 10 through the heat dissipation mechanism 60, thus improving the rainproof effect of the cabinet body 10.
