Description

Technical Field

[0001] This utility model relates to the field of rain shelter technology, and in particular to a rain shelter device suitable for outdoor transformer rectifiers. Background Technology

[0002] The transformer rectifier is the core of the power supply of the rectifier equipment, responsible for converting AC power into DC power for industrial use. However, outdoor rectifier transformers are subject to rain erosion for a long time, which can easily lead to a decline in insulation performance and corrosion of components. It is necessary to install a rainproof structure to protect the equipment and ensure stable operation in harsh weather conditions. For example, the patent application number CN202421797231.5 discloses a rainproof structure for outdoor transformer rectifiers. This utility model uses a T-shaped plate that slides and snaps into the inside of the T-shaped slot, thereby making it easy to disassemble and replace the inclined plate.

[0003] Existing tilting plate positioning structures, such as those used in the aforementioned transformer rectifier rain protection devices, employ rubber ball clamping. While this allows for quick assembly and disassembly, the rubber material is prone to irreversible deformation under long-term pressure, temperature changes, and environmental corrosion. This causes the positioning components to gradually lose their initial clamping force, resulting in positioning failure (increased clearance between the deformed ball and the positioning hole, leading to loosening and detachment under vibration or wind load), assembly obstruction (excessive deformation of the ball requires forceful disassembly and damages the mating surfaces), and protection degradation (tilt plate positioning deviation causes misalignment of the sealing structure). Especially under harsh operating conditions, frequent replacement of the rubber balls is required to maintain functionality, significantly increasing maintenance frequency and operating costs. Utility Model Content

[0004] This utility model embodiment relates to a rain shelter device suitable for outdoor transformer rectifiers. It only requires selective rotation of the screw to selectively implement or cancel rigid positioning of the two rain shelters. This not only makes it convenient to disassemble and replace the rain shelters, but also provides greater stability and a longer service life compared to the method of using rubber parts to clamp the rain shelters in the prior art.

[0005] In a first aspect, this utility model provides a rainproof device suitable for outdoor transformer rectifiers, specifically comprising: a connecting base, a guide member fixedly installed on the top of the connecting base; a fixing base fixedly installed on the top of the guide member; loading slots on the left and right sides of the fixing base; a top plate fixedly installed on the top of the fixing base; a loading strip slidably installed inside the loading slot; a positioning groove opened on the inner side of the loading strip; a rainproof plate fixedly installed on the outer side of the loading strip; a screw rotatably installed at the center position inside the fixing base; transmission seats slidably installed at the front and rear ends inside the fixing base; a transmission block fixedly installed at the outer end of the transmission seat; and positioning blocks slidably installed on the left and right sides inside the fixing base.

[0006] Furthermore, the interior of the guide member has an inclined structure; the left and right sides of the top plate protrude from the left and right sides of the fixing base; the left and right sides of the top plate protrude from the left and right sides of the fixing base.

[0007] Furthermore, a wire guide tube is fixedly installed on both the top plate and the fixed base; a sealing cylinder is threaded onto the top end of the wire guide tube.

[0008] Furthermore, the rain shelter has an inclined structure; and a guide groove is formed on the outer wall of the rain shelter.

[0009] Furthermore, the screw has two opposite threads arranged symmetrically front to back; the transmission seat is connected to the screw via threads; and the outer end of the transmission block has an inclined structure.

[0010] Furthermore, baffles are fixedly installed on the upper and lower sides of the positioning block; a spring is embedded between the baffles and the fixed seat.

[0011] Furthermore, the inner end of the positioning block has an inclined structure; the inclined structure of the inner end of the positioning block is basically in contact with the inclined structure of the transmission block; and an operating head is fixedly installed at the front end of the screw.

[0012] This utility model provides a rainproof device suitable for outdoor transformer rectifiers, which has the following beneficial effects:

[0013] 1. This utility model uses a rotatable screw to achieve rigid positioning of the rain shelter. The rotational motion is converted into axial displacement through threaded transmission, so that the positioning block and the positioning groove of the rain shelter form a stable connection. Compared with the traditional rubber clamping method, this design solves the problem of elasticity decay caused by rubber aging. It can still maintain reliable positioning strength in extreme temperature environments. During operation, the rain shelter can be quickly installed and removed by rotating the screw with only one hand. The positioning process is intuitive and has a self-locking function, which significantly improves the convenience of on-site maintenance and the stability of equipment operation.

[0014] 2. This utility model achieves multi-level waterproof protection through structural synergy. The top plate extends to form a shielding structure, which can effectively block rainwater from directly impacting the connection between the rain shelter and the fixed base. Even if water seeps into the connection, the guide component below the connection will collect and discharge the seepage, ensuring that a small amount of seepage can be quickly discharged, providing comprehensive rain protection for the transformer rectifier.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 7 Example 1:

[0029] This utility model proposes a rainproof device suitable for outdoor transformer rectifiers, comprising: a connecting base 1, a guide member 2 fixedly installed on the top of the connecting base 1; a fixing base 3 fixedly installed on the top of the guide member 2; loading slots 4 opened on the left and right sides of the fixing base 3; a top plate 5 fixedly installed on the top of the fixing base 3; a loading strip 8 slidably installed inside the loading slot 4; a positioning slot 9 opened on the inner side of the loading strip 8; a rainproof plate 10 fixedly installed on the outer side of the loading strip 8; a screw 11 rotatably installed in the center of the interior of the fixing base 3; a transmission seat 12 slidably installed at both the front and rear ends of the interior of the fixing base 3; a transmission block 13 fixedly installed at the outer end of the transmission seat 12; and positioning blocks 14 slidably installed on the left and right sides of the interior of the fixing base 3.

[0030] In Example 2, based on Example 1, the internal structure of the guide member 2 is inclined; the left and right sides of the top plate 5 protrude from the left and right sides of the fixing base 3; the top plate 5 and the fixing base 3 are jointly fixedly installed with a cable pass-through 6, the function of which is to carry the cable; a sealing cylinder 7 is threaded on the top of the cable pass-through 6, the function of which is to seal the cable pass-through 6 that does not carry the cable; the rain shelter plate 10 is inclined; a guide groove is opened on the outer wall of the rain shelter plate 10, and the inclined rain shelter plate 10 can play a role in protecting the transformer rectifier from rain, and since the left and right ends of the top plate 5 protrude from the fixing base 3, the top plate 5 can block the connection between the rain shelter plate 10 and the fixing base 3, which reduces the water seepage at the connection to a certain extent.

[0031] In Example 3, based on Example 2, the screw 11 has two opposite threads symmetrically arranged front and back; the transmission seat 12 is connected to the screw 11 via threads; the outer end of the transmission block 13 has an inclined structure; baffles 15 are fixedly installed on the upper and lower sides of the positioning block 14; a spring 16 is embedded between the baffle 15 and the fixed seat 3; the inner end of the positioning block 14 has an inclined structure; the inclined structure of the inner end of the positioning block 14 is basically in contact with the inclined structure of the transmission block 13; an operating head is fixedly installed at the front end of the screw 11. Even if water seeps into the connection between the rainproof plate 10 and the fixed seat 3, the seeping water will flow into the interior of the guide 2 because a guide 2 is provided below the connection. The guide 2 will then use the inclined structure at the bottom of its interior to guide the water out from the front and rear ends of the device, preventing the seeping water from contacting the transformer rectifier.

[0032] Working principle: In use, the rain shelter is fixed to a suitable position on the transformer rectifier via the connecting base 1. During rain, the tilted rain shelter 10 provides rain protection for the transformer rectifier. Since the left and right ends of the top plate 5 protrude from the fixing base 3, the top plate 5 can shield the connection between the rain shelter 10 and the fixing base 3, reducing water leakage at the connection point to a certain extent. Even if water leakage occurs at the connection between the rain shelter 10 and the fixing base 3, the lower part of the connection... The guide member 2 is used to guide the water, so the seepage water will flow into the interior of the guide member 2. The guide member 2 will then use the inclined structure at the bottom of its interior to guide the water out from the front and rear ends of the device, preventing the seepage water from contacting the transformer rectifier. When it is necessary to disassemble and replace the rain shield 10, simply rotate the screw 11 counterclockwise, so that it uses two opposite threads to slide the two transmission seats 12 and the two sets of transmission blocks 13 inward relative to each other. This allows the two sets of transmission blocks 13 to move inward and cancel the inclined push of the positioning block 14, so that the positioning block 14 does not... The rain shield 10 is then pushed inward by the spring 16, causing the outer end of the positioning block 14 to exit from the inside of the positioning groove 9. At the same time, the rigid positioning of the two rain shields 10 is canceled, which facilitates the disassembly of the rain shields 10. Then, the loading strip 8 on the replaced rain shield 10 is slid into the loading groove 4. After it is fully slid in, the screw 11 is rotated clockwise, so that the two transmission seats 12 and the two sets of transmission blocks 13 slide outward relative to each other using two opposite threads. The two sets of transmission blocks 13 push the inclined surface of the positioning block 14 by moving outward, so that the positioning block 14 is forced to move outward and insert into the inside of the positioning groove 9, restoring the rigid positioning of the rain shield 10 and ensuring the stability of the rain shield 10 during normal use. This utility model only requires selective rotation of the screw 11 to selectively implement or cancel the rigid positioning of the two rain shields 10. It not only makes the disassembly and replacement of the rain shields 10 more convenient, but also provides greater stability and a longer service life compared to the method of positioning the rain shields 10 by using rubber parts clamping in the prior art.
