A protective device for a transformer assembly frame

Abstract

This utility model discloses a protective device for a transformer assembly frame, comprising two columns, an mounting block on the outer circumference of each column, a disassembly and assembly component on the side wall of the mounting block, a frame on the other side wall of the mounting block, a heat dissipation component inside the frame, and a transformer body on the top of the frame. This protective device for the transformer assembly frame allows the mounting block to be fitted against the outer circumference of the column. After inserting a screw into a through hole and tightening the nut, the connection between the mounting block and the mounting plate becomes more secure. Pulling the limiting plate outward moves the moving rod outward. Rotating the locking plate releases the limiting plate, and the spring's rebound force moves the moving rod inward, causing the locking plate to engage with the side wall of the mounting plate, making the mounting plate and column fit more tightly and preventing loosening that could affect the installation of the protective device for the transformer assembly frame. It also facilitates disassembly and height adjustment to meet different needs. Furthermore, the heat dissipation component facilitates faster airflow and improves heat dissipation.

Description

Technical Field

[0001] This utility model relates to the field of transformer platform technology, specifically a protective device for a transformer complete equipment platform. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Transformers are the basic equipment for power transmission and distribution. The facility that installs transformers and ensures their safe operation is called a transformer platform. A transformer platform consists of high-voltage input lines, surge arresters, transformers, air switches, power metering devices, and low-voltage lines. The frame used to install the transformer is called a transformer platform.

[0003] The prior art patent document CN217361314U provides a protective device for a transformer assembly platform, including a platform body. A protective railing blocks the perimeter of the platform body, allowing workers to enter the railing through an opening door when inspecting the platform body. The protective railing's safety performance is improved through the use of a protective plate. An insulating board is laid on the surface of the platform body to facilitate workers' standing. Anti-slip strips provide a certain degree of anti-slip effect. An insulating protective sleeve covers the protective railing, and a thermally conductive silicone pad separates the platform body from the transformer body. The current is conducted to the ground through a grounding wire and a conductive wire, which provides a certain degree of insulation and protection for the working environment of the platform body, improving the safety of workers working at height.

[0004] Although the device has many beneficial effects, it still has the following problems: during the use of the device, it is not convenient to install the platform at different heights, and it is not convenient to adapt to different needs; secondly, the device relies solely on natural airflow during use, and the heat dissipation effect is not good enough, making the transformer prone to overheating and damage, which needs to be improved. In view of this, we propose a protective device for the transformer complete equipment platform. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned problems of inconvenience in installing the platform at different heights, difficulty in adapting to different needs, and insufficient heat dissipation due to reliance on natural airflow, which easily leads to overheating and damage to the transformer, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a protective device for a transformer assembly frame, which facilitates the installation of the frame at different heights to meet different needs, makes the installation more stable, facilitates air circulation, facilitates heat dissipation, and avoids overheating damage to the transformer.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A protective device for a transformer assembly frame includes two columns. Each column has a mounting block on its outer circumference. Each mounting block has a disassembly / assembly assembly on its side wall. The assembly includes two through holes on each side of the mounting block's side wall. A screw is slidably connected to the inner circumference of each through hole. One end of each screw has a mounting plate, and the other end has a nut threaded onto its outer circumference. Each side wall of the mounting block has a sliding groove at its bottom. Each groove has a spring on its side wall, and each spring has a moving rod at its other end. Each moving rod has a fixed shaft at one end of its side wall, and both ends of the fixed shaft have rotatably connected to clamping plates. Each moving rod has a limiting plate at its other end. A frame is located on the other side wall of the mounting block. A heat dissipation assembly is located inside the frame, and a transformer body is located on the top of the frame. The springs drive the moving rods inward, causing the clamping plates to tighten the mounting plates, preventing the mounting plates from tilting downwards due to gravity when tightening the nuts, thus ensuring stable installation.

[0012] As a preferred embodiment of the protective device for a transformer assembly frame according to this utility model, the heat dissipation component includes two ventilation slots formed on the top of the frame. Each ventilation slot has a filter screen on its top sidewall, and each filter screen has a fixing block on both sides of its top. Each fixing block has a screw hole on its top. A ventilation fan is located at the bottom of the sidewall of one ventilation slot, and a cooling fan is located at the bottom of the sidewall of the other ventilation slot. The ventilation fan and cooling fan are electrically connected to an external power supply. Both the ventilation fan and cooling fan are located at the bottom of the frame to prevent rainwater damage and to prevent rainwater from entering the transformer body through the ventilation slots.

[0013] As a preferred embodiment of the protective device for a transformer complete equipment frame according to this utility model, both the inner circumferential wall of the mounting block and the inner circumferential wall of the mounting plate are provided with anti-slip pads, and the anti-slip pads are made of TPE.

[0014] In a preferred embodiment of the protective device for a transformer complete equipment frame according to this utility model, the cross-sectional dimension of the limiting plate is larger than the cross-sectional dimension of the moving rod, and the length of the clamping plate is greater than the height of the moving rod.

[0015] In a preferred embodiment of the protective device for a transformer assembly frame according to this utility model, the ventilation fan and the cooling fan have opposite output directions, and the size of the filter screen matches the size of the ventilation slot. A filter screen that matches the size of the ventilation slot prevents gaps from forming between the filter screen and the ventilation slot, thus preventing impurities from entering.

[0016] As a preferred embodiment of the protective device for a transformer complete equipment frame according to the present invention, the frame is provided with protective plates on both sides of the top, and the protective plates are provided with top covers.

[0017] As a preferred embodiment of the protective device for a transformer assembly frame according to this utility model, the top cover is larger than the frame size, and the cross-section of the top cover is triangular.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The protective device for this type of transformer complete equipment frame involves fitting the mounting block against the outer circumference of the column, inserting the screw into the through hole and tightening the nut to ensure a more secure connection between the mounting block and the mounting plate. Pulling the limiting plate outward causes the moving rod to move outward, and rotating the locking plate releases the limiting plate. The spring's rebound force then causes the moving rod to move inward, thereby locking the locking plate against the side wall of the mounting plate, making the mounting plate fit more tightly against the column. This prevents loosening from affecting the installation of the protective device for the transformer complete equipment frame and facilitates disassembly and height adjustment to meet different needs.

[0021] The protective device of this type of transformer complete equipment frame draws external air into the top of the frame by turning on the ventilation fan, and draws out the hot air generated by the transformer body during use by turning on the cooling fan, which facilitates faster airflow and improves heat dissipation. The filter screen facilitates the filtration of impurities in the air to avoid damage to the transformer body. The bolt holes facilitate the disassembly and assembly of the fixing blocks, thereby making it easy to remove the filter screen for cleaning. Attached Figure Description

[0030] This utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a protective device for a transformer assembly platform, including:

[0035] Please see Figures 1-5 This embodiment of a protective device for a transformer assembly frame includes two columns 1. A mounting block 2 is snapped onto the outer circumference of each column 1. A disassembly / assembly assembly 3 is snapped onto the side wall of each mounting block 2. The disassembly / assembly assembly 3 includes two through holes 301 on both sides of the side wall of the mounting block 2. A screw 302 is slidably connected to the inner circumference of each through hole 301. A mounting plate 303 is fixed to one end of each screw 302, and a nut 304 is threaded onto the outer circumference of the other end of each screw 302. Sliding grooves 305 are formed on the bottom of both sides of the side wall of the mounting block 2. Springs 306 are fixed to the side walls of both sliding grooves 305, and moving rods 307 are fixed to the other ends of both springs 306. Fixed shafts 308 are fixedly threaded through one end of the side wall of each moving rod 307. Clamping plates 309 are rotatably connected to both ends of the outer circumference of each fixed shaft 308. Each movable rod 307 has a limiting plate 310 fixed at its other end. A frame 4 is welded to the other side wall of the mounting block 2. A heat dissipation component 5 is fixed inside the frame 4. A transformer body 6 is fixed on the top of the frame 4. The mounting block 2 is attached to the outer circumference of the column 1. After inserting the screw 302 into the through hole 301, the nut 304 is tightened to make the connection between the mounting block 2 and the mounting plate 303 more stable. Pulling the limiting plate 310 outward will move the movable rod 307 outward. After rotating the locking plate 309, the limiting plate 310 is released. The spring force of the spring 306 will move the movable rod 307 inward, so that the locking plate 309 will engage with the side wall of the mounting plate 303, making the mounting plate 303 more tightly attached to the column 1. This will prevent loosening from affecting the installation of the protective device of the transformer complete equipment frame and facilitate disassembly and height adjustment to meet different needs.

[0036] It is worth noting that, specifically, for the heat dissipation of the transformer body 6, the heat dissipation component 5 includes two ventilation slots 501 opened on the top of the platform 4. Filters 502 are snapped onto the top of the side walls of both ventilation slots 501. Fixing blocks 503 are fixed on both sides of the top of the two filters 502. Screw holes 504 are opened on the top of the two fixing blocks 503. A ventilation fan 505 is fixed to the bottom of the side wall of one ventilation slot 501, and a cooling fan 506 is fixed to the bottom of the side wall of the other ventilation slot 501. The ventilation fan 505 and the cooling fan 506 are electrically connected to an external power supply. By turning on the ventilation fan 505, external air flows into the top of the platform 4. By turning on the cooling fan 506, hot air generated by the transformer body 6 during use flows out, which facilitates faster airflow and improves the heat dissipation effect. The filters 502 facilitate the filtering of impurities in the air to avoid damaging the transformer body 6. The screw holes 504 are screwed out to facilitate the installation and removal of the fixing blocks 503, thereby facilitating the removal of the filters 502 for cleaning.

[0037] Next, in order to improve the installation stability of the protective device of the transformer complete equipment platform, specifically, anti-slip pads 311 are fixed on the inner circumference of the mounting block 2 and the inner circumference of the mounting plate 303. The anti-slip pads 311 are made of TPE. The TPE anti-slip pads 311 can increase the friction and prevent the mounting block 2 and the mounting plate 303 from sliding off the outer circumference of the column 1.

[0038] Meanwhile, in order to facilitate the engagement of the mounting plate 303, specifically, the cross-sectional dimension of the limiting plate 310 is larger than that of the moving rod 307, and the length of the clamping plate 309 is greater than that of the moving rod 307. The limiting plate 310, which is larger than the cross-sectional dimension of the moving rod 307, is used to limit the clamping plate 309 and prevent it from continuing to rotate. The clamping plate 309, which is longer than the height of the moving rod 307, is used to facilitate the engagement of the mounting plate 303 after the clamping plate 309 rotates.

[0039] Furthermore, to facilitate air circulation, specifically, the ventilation fan 505 and the cooling fan 506 have opposite output directions, and the size of the filter 502 matches the size of the ventilation slot 501. The ventilation fan 505 and the cooling fan 506 with opposite output directions facilitate the formation of an air circulation channel, resulting in better heat dissipation.

[0040] It is worth noting that, in order to improve safety, protective plates 7 are fixed on both sides of the top of the platform 4, and a top cover 8 is fixed on the top of the protective plates 7. The protective plates 7 are used to improve the protection performance and prevent workers from falling when they are inspecting the transformer body 6. The top cover 8 is used to protect against rain.

[0041] Finally, to facilitate the guidance of rainwater to slide off, specifically, the size of the top cover 8 is larger than that of the platform 4, and the cross-section of the top cover 8 is triangular. By using the top cover 8, which has a larger size than the platform 4 and a triangular cross-section, it is easier to guide rainwater to slide off to the outside, thus preventing the transformer body 6 from being eroded by rainwater.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0044] Ventilation fan 505: DE07020B12U-FAR;

[0045] Cooling fan 506: DE07020B12U-FAR.

[0046] Combination Figures 1-5 The protective device for a transformer assembly frame according to this embodiment is used in the following specific process:

[0047] 1: When this device is needed as a protective device for the transformer complete equipment platform, fit the mounting block 2 against the outer circumference of the column 1, insert the screw 302 into the through hole 301 and tighten the nut 304, pull the limiting plate 310 outward to drive the moving rod 307 to move outward, rotate the clamping plate 309 and release the limiting plate 310, the rebound force of the spring 306 drives the moving rod 307 to move inward so that the clamping plate 309 engages with the side wall of the mounting plate 303;

[0048] 2: Start the ventilation fan 505 to draw external air into the top of the stand 4, start the cooling fan 506 to draw out the hot air generated by the transformer body 6 during use, screw in the bolt into the screw hole 504 to install the filter screen 502 to filter impurities in the air, unscrew the bolt to remove the fixing block 503 to remove the filter screen 502 for cleaning.
