Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to an outdoor electrical cabinet with a rainproof structure. Background Art

[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. The materials used to make electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Many electrical cabinets are set up outdoors and are exposed to wind and rain all year round, especially the erosion of rain. It not only corrodes the outer shell of the electrical cabinet, but once rainwater enters the interior of the electrical cabinet, it will damage the electrical components inside the electrical cabinet, and even make all the internal components of the entire electrical cabinet unable to operate normally, causing safety hazards.

[0003] For example, an outdoor rainproof electrical cabinet with publication number CN210670928U includes a box body, a box cover is arranged directly in front of the box body, the rear side of the left side of the box cover is hinged to the front side of the left side of the box body, a mounting groove is opened on the top of the front side of the box cover, an observation glass is arranged inside the mounting groove, and a fixing device is fixedly connected to the middle part of the right side of the box cover, most of the rainwater is blocked by the rain shield, and the rainwater is guided to the front side of the electrical cabinet with the help of the rain guide groove, which basically ensures the normal use of the electrical components inside the electrical cabinet, the water absorption plate absorbs the rainwater between the rain shield and the installation position, thereby enhancing the rainproof performance of the electrical cabinet and ensuring the normal use of the internal electrical components, and the water-proof heat dissipation holes block splashing rainwater from entering the electrical cabinet while ensuring the heat dissipation performance of the electrical cabinet, thereby protecting the electrical components from damage.

[0004] The above patent uses a rain shield to block rainwater, but the rain shield is large in size and occupies a large space, which affects the use of the space next to the electrical cabinet. When it rains, rainwater will fall from the front end of the electrical cabinet. If the door of the electrical cabinet is opened at this time, rainwater will easily penetrate into the door gap, which is inconvenient to use. Therefore, we propose an outdoor electrical cabinet with a rainproof structure to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an outdoor electrical cabinet with a rainproof structure to solve the problem that the above background technology proposes to use a rain shield to block rainwater, but the rain shield is large in size and occupies a large space, which affects the use of the space next to the electrical cabinet.

[0006] To achieve the above object, the present invention provides the following technical solutions: an outdoor electrical cabinet with a rainproof structure, comprising an electrical cabinet body and a top plate mechanism installed at the upper end of the electrical cabinet body;

[0007] Also includes:

[0008] Support mechanism, the support mechanism is arranged at the upper end of the top plate mechanism, and the support mechanism includes an outer sleeve fixedly installed on the top plate mechanism and an inner sleeve threadedly connected to the upper end of the outer sleeve;

[0009] Rain shield, the rain shield is rotatably installed at the upper end of the inner sleeve. A groove is formed in the middle of the rain shield, and a through hole is formed in the middle of the groove. The through hole is communicated with the inner sleeve. Extension plates are rotatably installed at both ends of the rain shield, and a connecting mechanism is jointly arranged between the extension plates and the outer sleeve.

[0010] By adopting the above technical solutions, the height of the rain shield can be adjusted, so it can be adapted according to the space in the area where the electrical cabinet body is located, and it will not affect the use of other mechanisms. Extension plates are rotated at both ends of the rain shield. After the two are unfolded, the shielding range at the top of the electrical cabinet body can be increased, and the rain shielding range is large.

[0011] Preferably, the top plate mechanism includes a top cover plate fixedly installed at the upper end of the electrical cabinet body and an L-shaped plate fixedly installed on the outer periphery of the top cover plate. The height of the L-shaped plate is higher than that of the top cover plate. The top plate mechanism further includes a diversion groove formed between the top cover plate and the L-shaped plate.

[0012] By adopting the above technical solutions, the middle of the top cover plate is high at both ends and low. The L-shaped plate is arranged around the outer periphery of the top cover plate. Rainwater slides down along the top cover plate and flows into the diversion groove at the upper end of the L-shaped plate.

[0013] Preferably, the outer sleeve and the inner sleeve are communicated with each other. A piston block is slidably installed in the inner sleeve. A piston rod is fixedly installed at the lower end of the piston block. A rubber plug slides at the lower end of the piston rod. The rubber plug is fixed on the inner wall of the outer sleeve. The rubber plug slides in the outer sleeve. An outlet is formed on the side wall of the inner sleeve. A sealing block is fixedly installed on the outer periphery of the piston rod. The outlet is formed between the piston block and the sealing block.

[0014] By adopting the above technical solutions, when it rains, rainwater enters the inner sleeve through the groove and the through hole and is blocked by the piston block thereon. The gravity of the water presses down the piston block and the sealing block, and the gas in the chamber is squeezed downward, which can lift one end of the connecting mechanism and extend the other end, and the extension plate can be unfolded.

[0015] Preferably, sealing strips are fixedly installed at both ends of the rain shield, the sealing strips are located at the upper ends of the extension plates, and sliding grooves are formed on the inner walls of the extension plates.

[0016] By adopting the above technical solutions, the sealing strips are arranged at the junction of the rain shield and the extension plates, which greatly reduces the water leakage at the junction.

[0017] Preferably, the connecting mechanism includes a hollow tube and a connecting rod slidably connected to the hollow tube. The hollow tube communicates with the outer sleeve. A slider is rotatably installed at one end of the connecting rod away from the hollow tube. The slider is slidably connected to the chute. A piston head is slidably installed inside the hollow tube. The piston head is fixedly connected to the connecting rod.

[0018] By adopting the above technical solution, the gravity of water presses down the piston block and the sealing block, the gas in the chamber is squeezed downward, air enters the hollow tube, and the piston block and the connecting rod are pushed outwards. The hollow tube and the connecting rod extend, and the extension plate can be automatically unfolded.

[0019] Preferably, a through hole is formed in the side wall of the outer sleeve. The hollow tube is inserted through the through hole. The hollow tube is rotatably connected to the outer sleeve through a rotating shaft. A rubber ring is fixedly installed between the inner wall of the through hole and the outer wall of the hollow tube. An elastic member is connected between the rotating shaft and the piston head.

[0020] By adopting the above technical solution, when the hollow tube and the connecting rod extend, the elastic member is unfolded. When the rain stops, the rainwater drains out from the water outlet, the upper end of the piston block loses pressure, and the elastic member rebounds. The mechanism can be reset, which is convenient for secondary use. The extension plate can also reduce the area of the rain shield.

[0021] Preferably, a diversion mechanism is provided at one end of the rain shield. The diversion mechanism includes a first support rod installed on the side wall of the extension plate and a horizontal folding shed installed between the two first support rods. A second support rod is vertically arranged on the side wall of the extension plate. A vertical folding shed is jointly installed between the first support rod and the second support rod. The horizontal folding shed and the vertical folding shed are interconnected.

[0022] By adopting the above technical solution, the creases at the upper ends of the horizontal folding shed and the vertical folding shed are all horizontal movements, which can not only block the rainwater, but also control the direction of the rainwater, ensuring that the rainwater does not fall from the place of the door of the electrical cabinet body.

[0023] Preferably, two vertical rods are fixedly installed at the lower end of the rain shield. An arc-shaped keel frame is jointly connected between the vertical rods and the end of the vertical folding shed away from the first support rod. A clamping groove is formed in the side wall of the extension plate. The first support rod and the second support rod are connected to the clamping groove through clamping blocks.

[0024] By adopting the above technical solution, through the cooperation between the clamping groove, the first support rod, the second support rod and the clamping block, the disassembly and assembly of the vertical folding shed and the horizontal folding shed are facilitated. By setting the arc-shaped keel frame, it is convenient to support the horizontal folding shed, and the rainproof effect is good.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: The rain shield occupies a small space. When it rains, it can automatically expand the rain shielding area, with a large rain shielding range, and can also control the direction of rainwater flow to prevent rainwater from flowing down from the door direction. The specific content is as follows;

[0026] 1. The top of the electrical cabinet body is connected to the rain shield through a support mechanism, and the height of the rain shield is adjustable. Therefore, it can be adapted according to the space in the area where the electrical cabinet body is located without affecting the use of other mechanisms. The two ends of the rain shield are rotated with extension plates. After the two are unfolded, the shielding range on the top of the electrical cabinet body can be increased, with a large rain shielding range, which is convenient for outdoor use.

[0027] 2. There is a sealed chamber among the sealing block, rubber plug, inner sleeve, outer sleeve, hollow tube, and piston head. The chamber is filled with gas. When it rains, rainwater enters the inner sleeve through the groove and through hole and is blocked by the piston block thereon. The gravity of the water presses down the piston block and the sealing block, and the gas in the chamber is squeezed downward, which can lift one end of the connecting mechanism and extend the other end. Air enters the hollow tube and squeezes out the piston block and connecting rod outward. The hollow tube and the connecting rod elongate, and the extension plate can be automatically unfolded, further playing a rainproof effect and being convenient for popularization and use.

[0028] 3. When the hollow tube and the connecting rod elongate, the elastic member is unfolded. When the rain stops, the rainwater drains out from the water outlet, the upper end of the piston block loses pressure, and the elastic member rebounds. The hollow tube, connecting rod, sealing block, rubber plug, inner sleeve, outer sleeve, and extension plate can all return to their original positions, which is convenient for secondary use. The extension plate can also reduce the area of the rain shield, which is convenient for the use of other devices.

[0029] 4. The creases at the upper ends of the horizontal folding shed and the vertical folding shed are all horizontal movements. It can not only block rainwater but also control the direction of rainwater flow, ensuring that rainwater does not fall from the place of the door of the electrical cabinet body but from both ends of the electrical cabinet body, greatly ensuring that rainwater does not seep in through the door gap, with good waterproof effect. Since one end of the vertical folding shed is connected to the side wall of the extension plate, when the extension plate is unfolded, it can drive the vertical folding shed to expand the shielding area, further playing a rain shielding effect on the electrical cabinet body, with a relatively large rain shielding range.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1: Please refer to Figures 1-3 , the present invention provides a technical solution: an outdoor electrical cabinet with a rainproof structure, including an electrical cabinet body 1 and a top plate mechanism 2 installed on the upper end of the electrical cabinet body 1;

[0041] It further includes:

[0042] A support mechanism 3, the support mechanism 3 is arranged on the upper end of the top plate mechanism 2, and the support mechanism 3 includes an outer sleeve 31 fixedly installed on the top plate mechanism 2 and an inner sleeve 32 threadedly connected to the upper end of the outer sleeve 31;

[0043] The rain shield 4 is rotatably installed at the upper end of the inner sleeve 32. A groove 41 is formed in the middle of the rain shield 4, and a through hole 411 is formed in the middle of the groove 41. The through hole 411 communicates with the inner sleeve 32. Extension plates 43 are rotatably installed at both ends of the rain shield 4, and a connecting mechanism 6 is jointly provided between the extension plates 43 and the outer sleeve 31.

[0044] The top plate mechanism 2 includes a top cover plate 21 fixedly installed at the upper end of the electrical cabinet body 1 and an L-shaped plate 22 fixedly installed on the outer periphery of the top cover plate 21. The height of the L-shaped plate 22 is higher than that of the top cover plate 21. The top plate mechanism 2 further includes a diversion groove 23 formed between the top cover plate 21 and the L-shaped plate 22.

[0045] The top of the electrical cabinet body 1 is connected to the rain shield 4 through a support mechanism 3, and the support mechanism 3 is composed of an outer sleeve 31 and an inner sleeve 32, and its height is adjustable. Therefore, it can be adapted according to the space of the area where the electrical cabinet body 1 is located without affecting the use of other mechanisms. At the same time, the rain shield 4 can block the upper end of the electrical cabinet body 1, which is convenient for rain shielding and sun shading. Moreover, extension plates 43 are rotatable at both ends of the rain shield 4. After the two are unfolded, the shielding range of the top of the electrical cabinet body 1 can be increased, and the rain shielding range is large. Through the cooperation between the groove 41, the through hole 411, the outer sleeve 31, the inner sleeve 32, and the connecting mechanism 6, when it rains, rainwater enters the groove 41, and the connecting mechanism 6 unfolds and rotates, which can automatically unfold the extension plates 43 without manual operation, and the use effect is good.

[0046] The middle of the top cover plate 21 is high at both ends and low. The L-shaped plate 22 is arranged around the outer periphery of the top cover plate 21. Rainwater slides down along the top cover plate 21 and flows into the diversion groove 23 at the upper end of the L-shaped plate 22. A rainwater outlet is formed on the rear L-shaped plate 22, and the rainwater can be discharged, which can reduce the flow of rainwater from the direction of the door of the electrical cabinet body 1 and affect the seepage of water when opening the door during rain.

[0047] Embodiment 2: Please refer to Figures 1-3 , the outer sleeve 31 and the inner sleeve 32 communicate with each other. A piston block 33 is slidably installed in the inner sleeve 32. A piston rod 34 is fixedly installed at the lower end of the piston block 33. A rubber plug 35 slides on the lower end of the piston rod 34. The rubber plug 35 is fixed on the inner wall of the outer sleeve 31. The rubber plug 35 slides in the outer sleeve 31. A water outlet 36 is formed on the side wall of the inner sleeve 32. A sealing block 37 is fixedly installed on the outer periphery of the piston rod 34. The water outlet 36 is formed between the piston block 33 and the sealing block 37.

[0048] There is a sealed chamber between the sealing block 37, the rubber plug 35, the inner sleeve 32 and the outer sleeve 31. The chamber is filled with gas. When it rains, rainwater enters the inner sleeve 32 through the groove 41 and the through hole 411 and is blocked by the piston block 33. The gravity of the water presses down the piston block 33 and the sealing block 37, and the gas in the chamber is squeezed downward, which can lift one end of the connecting mechanism 6 and extend the other end, and the extension plate 43 can be unfolded, facilitating the automatic rain shielding of the extension plate 43. When the rainwater accumulates to a certain extent, the piston block 33 slides to the lower end of the water outlet 36, and the rainwater in the inner sleeve 32 can be discharged through the water outlet 36, facilitating the discharge of rainwater.

[0049] Sealing strips 42 are fixedly installed at both ends of the rain shielding plate 4. The sealing strips 42 are located at the upper end of the extension plate 43, and sliding grooves 431 are formed on the inner wall of the extension plate 43.

[0050] The sealing strip 42 is arranged at the junction of the rain shielding plate 4 and the extension plate 43, greatly reducing water leakage at the junction.

[0051] The connecting mechanism 6 includes a hollow tube 61 and a connecting rod 62 slidably connected to the hollow tube 61. The hollow tube 61 is communicated with the outer sleeve 31. A slider 611 is rotatably installed at one end of the connecting rod 62 away from the hollow tube 61. The slider 611 is slidably connected with the sliding groove 431. A piston head 64 is slidably installed inside the hollow tube 61, and the piston head 64 is fixedly connected with the connecting rod 62.

[0052] The hollow tube 61 is a tubular mechanism with openings at both ends. One end is communicated with the chamber filled with gas, and the other end slides with the piston head 64. Rainwater enters the inner sleeve 32 through the groove 41 and the through hole 411 and is blocked by the piston block 33. The gravity of the water presses down the piston block 33 and the sealing block 37, and the gas in the chamber is squeezed downward. Air enters the hollow tube 61 and displaces the piston block 33 and the connecting rod 62 outward. The hollow tube 61 and the connecting rod 62 extend, and the extension plate 43 can be automatically unfolded, further playing a rain shielding effect and facilitating popularization and use.

[0053] A through hole 311 is formed on the side wall of the outer sleeve 31. The hollow tube 61 is inserted and connected with the through hole 311. The hollow tube 61 is rotatably connected with the outer sleeve 31 through a rotating shaft 312. A rubber ring 313 is fixedly installed between the inner wall of the through hole 311 and the outer wall of the hollow tube 61. An elastic member 65 is connected between the rotating shaft 312 and the piston head 64.

[0054] The rubber ring 313 ensures the sealing of the through hole 311 and the mobility of the hollow tube 61, which is convenient for use. When the hollow tube 61 and the connecting rod 62 are extended and the elastic member 65 is unfolded, when the rain stops, rainwater is discharged from the water outlet 36, the upper end of the piston block 33 loses pressure, and the elastic member 65 rebounds. The hollow tube 61, the connecting rod 62, the sealing block 37, the rubber plug 35, the inner sleeve 32, the outer sleeve 31, and the extension plate 43 can all be reset, which is convenient for secondary use. The extension plate 43 can also reduce the area of ​​the rain shield 4 to facilitate the use of other devices.

[0055] Example 3: Please refer to Figures 1-3 A guide mechanism 5 is provided at one end of the rain shield 4, and the guide mechanism 5 includes a first support rod 51 installed on the side wall of the extension plate 43 and a horizontal folding shed 52 installed between the two first support rods 51, a second support rod 53 is vertically arranged on the side wall of the extension plate 43, and a vertical folding shed 54 is installed between the first support rod 51 and the second support rod 53, and the horizontal folding shed 52 and the vertical folding shed 54 are connected to each other.

[0056] The folds on the upper ends of the horizontal folding shed 52 and the vertical folding shed 54 are both horizontal, which can not only block rain, but also control the direction of rain, ensuring that rain will not fall from the door of the electrical cabinet body 1, but fall from both ends of the electrical cabinet body 1, which greatly ensures that rain will not penetrate through the door gap and has a good waterproof effect. Since one end of the vertical folding shed 54 is connected to the side wall of the extension plate 43, when the extension plate 43 is unfolded, it can drive the vertical folding shed 54 to expand the shielding area, further playing a rain-shielding effect on the electrical cabinet body 1, and the rain-shielding range is relatively large.

[0057] Two vertical rods 44 are fixedly installed at the lower end of the rain shield 4. The vertical rods 44 and the end of the vertical folding shed 54 away from the first support rod 51 are commonly connected with an arc-shaped keel frame 55. A snap-in groove 432 is opened on the side wall of the extension plate 43. The first support rod 51 and the second support rod 53 are connected to the snap-in groove 432 through a snap-in block 56.

[0058] Through the cooperation among the snap-in groove 432, the first support rod 51, the second support rod 53, and the snap-in block 56, the vertical folding shed 54 and the horizontal folding shed 52 can be easily assembled and disassembled. By setting the arc-shaped keel frame 55, the horizontal folding shed 52 can be easily supported, and the rainproof effect is good.

[0059] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
