Abstract
Description
Technical Field
[0001] This utility model belongs to the field of protective rain shelter technology, and in particular relates to an automatic opening and closing rain shelter structure for electrical equipment. Background Technology
[0002] Rain shelter structures for electrical equipment are protective devices used to protect outdoor electrical equipment from rainwater erosion. They are widely used in the protection of outdoor electrical facilities such as distribution boxes, transformers, and communication base stations. Their main function is to prevent rainwater from splashing directly onto the surface of the electrical equipment or entering the equipment, thereby avoiding equipment failures caused by moisture or short circuits, ensuring the normal operation of the electrical equipment, extending the service life of the equipment, and reducing safety hazards and maintenance costs caused by equipment damage.
[0003] Among existing protective canopies for electrical equipment, some adopt a fixed and unfolding structure design. While these canopies can provide shelter from rain on rainy days, their fixed covering state can hinder air circulation around electrical equipment on non-rainy days, affecting the equipment's natural heat dissipation. Especially in hot weather, the heat generated by the equipment is difficult to dissipate effectively, easily leading to excessively high equipment temperatures, which in turn affects its operational stability and service life. Other canopies use a manual opening and closing mechanism, requiring manual operation to unfold and retract. However, in sudden rainstorms, the inability to close the canopy in time often results in the electrical equipment being damaged by rainwater. At the same time, manual operation requires dedicated personnel to be on duty, which not only increases labor costs but also poses a risk of untimely protection due to human negligence.
[0004] To address these issues, we provide an automatic opening and closing rain-proof structure for electrical equipment. Utility Model Content
[0005] The purpose of this utility model is to provide an automatic opening and closing rain shelter structure for electrical equipment. It uses a double-rope electric winch and a spring to drive the nested rain shelter to open and close automatically. It also incorporates a raindrop sensor, a temperature and humidity sensor and a controller to achieve environmental adaptive control. This solves the problems that existing electrical equipment protective rain shelters are mostly fixed structures, which can easily block equipment and affect heat dissipation on non-rainy days, or require manual operation to open and close, resulting in insufficient intelligence and inconvenience.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] The present invention is further configured such that the elastic device includes a fixed seat fixedly connected to the inner side of the main frame, and push springs are fixedly connected to both sides of the fixed seat. A baffle is fixedly connected to the opposite side of the two third canopies, and the baffle compresses the push spring when the third canopy is retracted.
[0011] The present invention is further configured such that brush strips that fit the top of adjacent canopies are fixedly connected to both ends of the bottom of the canopy, the bottom of the top plate of the first canopy, and the bottom of the top plate of the second canopy.
[0012] The present invention is further provided that a counterweight strip is fixedly connected to the bottom of the top plate of the third canopy.
[0013] The present invention is further configured such that the limiter includes a side plate fixedly connected to the outside of the main frame, and the inner side of the side plate is fixed with a first limit plate, a second limit plate and a third limit plate for blocking the first canopy, the second canopy and the third canopy in sequence, and the lengths of the first limit plate, the second limit plate and the third limit plate increase in sequence.
[0014] The present invention is further provided that a toggle block is fixedly connected to the top of the second and third canopies near the middle of the inner edge.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] Example 1
[0029] Please see Figures 1 to 4 This utility model is an automatic opening and closing rain shelter structure for electrical equipment, including an n-shaped main frame 100; two symmetrically distributed fixed shafts 101 are fixedly connected to both sides of the main frame 100 near the bottom; the two opposing fixed shafts 101 are rotatably connected to a first rain shelter 300, a second rain shelter 400, and a third rain shelter 500 nested from the outside in. The first rain shelter 300, the second rain shelter 400, and the third rain shelter 500 are all inverted L-shapes. An arc-shaped roof 200 is fixedly connected to the top of the main frame 100, and a double-rope electric winch 700 is fixedly connected to the top of the inner side of the main frame 100. The two free ends of the double-rope electric winch 700 are respectively fixedly connected to the two third rain shelters 300. At the upper center of the canopy 500, two limiters 1300 are fixedly connected to both sides of the main frame 100 to limit the opening angle of the first canopy 300, the second canopy 400, and the third canopy 500. Two elastic devices 1200 are fixedly connected to the inner side of the main frame 100 to open the first canopy 300, the second canopy 400, and the third canopy 500. The first canopy 300, the second canopy 400, and the third canopy 500 adopt a nested design from the outside to the inside, which can save storage space, facilitate compact placement in non-rainy weather, and facilitate heat dissipation of electrical equipment. The combination of the double-rope electric winch 700 and the elastic device 1200 realizes the automatic opening and closing function of the canopy, thereby closing or opening the canopy in time.
[0030] Specifically, the third canopy 500 is externally fixedly connected to a stop bar 501 for moving the first canopy 300 and the second canopy 400. The stop bar 501 can push the first canopy 300 and the second canopy 400 to rotate when the third canopy 500 is stored, so that the first canopy 300, the second canopy 400 and the third canopy 500 can be stored.
[0031] The operation process of this embodiment is as follows: When there is no need for rain shelter, the double-rope electric winch 700 starts and tightens the rope. The rope pulls the third canopy 500 to rotate inward around the fixed shaft 101. At this time, the baffle 501 on the outside of the third canopy 500 moves accordingly, pushing the second canopy 400 and the first canopy 300 to rotate inward synchronously. Since the first canopy 300, the second canopy 400 and the third canopy 500 are inverted L-shaped and adopt a nested design from the outside to the inside, they can be naturally stored layer by layer during the rotation, which saves a lot of space and makes the overall structure more compact. This avoids the canopy occupying too much space and affecting the heat dissipation of electrical equipment when it is not raining. At the same time, during the storage process, the third canopy 500 will compress the elastic device 1200, so that the elastic device 1200 stores elastic potential energy.
[0032] Example 2
[0033] Please see Figures 1 to 6 Based on the first specific embodiment, a temperature and humidity sensor 900 is fixedly connected to the outside of the main frame 100, a raindrop sensor 600 is fixedly connected to the top of the canopy 200, and a controller 800 is fixedly connected to the top of the inner side of the main frame 100. The controller 800 is used to receive signals from the temperature and humidity sensor 900 and the raindrop sensor 600 and to control the operation of the double-rope electric winch 700. The temperature and humidity sensor 900 and the raindrop sensor 600 can monitor the temperature, humidity and rainfall of the external environment in real time. The controller 800 can automatically control the operation of the double-rope electric winch 700 according to the monitoring signals, so that the rain shelter structure has environmental self-adaptation capability, realizes automatic rain shelter protection under unattended operation, and improves the level of intelligence in use.
[0034] Specifically, the elastic device 1200 includes a fixed base 1201 fixedly connected to the inner side of the main frame 100. Push springs 1202 are fixedly connected to both sides of the fixed base 1201. Baffles 1203 are fixedly connected to the opposite side of the two third canopies 500. When the third canopy 500 is closed, the baffles 1203 compress the push springs 1202. When the third canopy 500 is closed, the push springs 1202 are compressed by the baffles 1203 to store elastic potential energy. When unfolded, the push springs 1202 release potential energy to assist in pushing the third canopy 500 to unfold.
[0035] Furthermore, a counterweight 502 is fixedly connected to the bottom of the top plate of the third canopy 500. The counterweight 502 can make the center of gravity of the third canopy 500 deviate from the main frame 100, so that the third canopy 500 can be unfolded smoothly.
[0036] The limiter 1300 includes a side plate 1301 fixedly connected to the outside of the main frame 100. The inner side of the side plate 1301 is fixed with a first limiting plate 1302, a second limiting plate 1303, and a third limiting plate 1304 that are used to block the first canopy 300, the second canopy 400, and the third canopy 500 in sequence. The lengths of the first limiting plate 1302, the second limiting plate 1303, and the third limiting plate 1304 increase sequentially. The side plate 1301 of the limiter 1300 provides reliable installation support for each limiting plate. The design of the first limiting plate 1302, the second limiting plate 1303, and the third limiting plate 1304 increasing sequentially can respectively correspond to and limit the maximum unfolding angle of the first canopy 300, the second canopy 400, and the third canopy 500.
[0037] Both the second canopy 400 and the third canopy 500 have a lever block 1400 fixedly connected to the top near the middle of the inner edge.
[0038] The operation process of this embodiment is as follows: When it rains, the raindrop sensor 600 detects rainfall, and at the same time, the temperature and humidity sensor 900 monitors the ambient temperature and humidity. Then, the sensor transmits the signal to the controller 800, and the controller 800 then instructs the double-rope electric winch 700 to loosen the rope. At this time, the compressed push spring 1202 in the elastic device 1200 releases elastic potential energy, and pushes the third canopy 500 to rotate outward around the fixed axis 101 through the baffle 1203. The counterweight bar 502 at the bottom of the top plate of the third canopy 500 causes the center of gravity to deviate from the main frame 100, further assisting its smooth unfolding. Then, the two actuating blocks 1400 can drive it in sequence to avoid the unfolding speed being affected by structural jamming. During the unfolding of the third canopy 500, its external baffles 501 sequentially drive the second canopy 400 and the first canopy 300 to unfold, until the first canopy 300 is blocked by the first limiting plate 1302, the second canopy 400 is blocked by the second limiting plate 1303, and the third canopy 500 is blocked by the third limiting plate 1304, thereby achieving automatic rain protection without human intervention and preventing damage to electrical equipment.
[0039] Example 3
[0040] Please see Figures 1 to 4 Based on specific embodiment one and specific embodiment two, brush strips 1100 that fit the top of adjacent canopies are fixedly connected to both ends of the bottom of the canopy 200, the bottom of the top plate of the first canopy 300 and the bottom of the top plate of the second canopy 400.
[0041] The operation process of this embodiment is as follows: the brush strip 1100 is attached to the top of the adjacent awning, which can effectively fill the gap between the awnings, prevent debris from entering from the gap, improve the overall rainproof sealing, and can also play a role in venting in windy weather, improving wind resistance. At the same time, the top of the corresponding awning can be cleaned when storing it.
