Description

Technical Field

[0001] This utility model relates to the field of transformers, and more particularly to a transformer housing designed to prevent detachment. Background Technology

[0002] The transformer casing is an external structure used to protect the internal components of the transformer. It prevents dust, moisture, foreign objects, etc. from entering the transformer, protects the internal electrical components from environmental factors, and also prevents personnel from directly contacting the live parts inside the transformer, thus avoiding safety accidents such as electric shock.

[0003] Existing anti-detachment transformer casings lack an automatic lubrication structure for the door hinges. After long-term use, the hinges are prone to wear, leading to difficulties in opening and closing the door and noise. Furthermore, the lack of an external protective structure for the hinges means they cannot be shielded, making them susceptible to corrosion from rain and dust.

[0004] Therefore, in view of the problem that the existing anti-detachment transformer housing lacks an automatic lubrication structure and an external protection structure, which makes the hinges susceptible to wear and corrosion, there is an urgent need to design a new type of anti-detachment transformer housing. Utility Model Content

[0005] In order to overcome the problem that the existing anti-detachment transformer casing lacks an automatic lubrication structure and an external protective structure, which makes the hinges susceptible to wear and corrosion.

[0006] The technical solution of this utility model is as follows: an anti-fall-off transformer shell, including a protective shell; it also includes a placement box, an observation slot, a plastic container, a press-type nozzle, a pressure rod, a positioning cover, a sliding cover, and a slider. The front surface of the protective shell has two symmetrical protective doors connected by hinges. A placement box is provided on the front surface of the protective shell corresponding to the four hinge positions. An observation slot is opened on the front surface of the placement box. A plastic container is placed inside the placement box. A press-type nozzle is installed at the opening of the plastic container. A pressure rod is provided on the front surface of the two protective doors corresponding to the press-type nozzle positions. A latch is provided in the middle of the front surface of the two protective doors. A positioning cover is provided on the front surface of the protective shell corresponding to the protective door hinge positions. A sliding cover is provided on the inner surface of the positioning cover. Sliders are provided on the upper and lower surfaces of the sliding cover. The sliding cover is slidably connected to the positioning cover through the sliders.

[0007] Preferably, by setting a pressure rod, when the protective door is opened, the pressure rod can be moved synchronously. After the pressure rod moves a certain distance, it will press the press-type nozzle, thereby spraying the lubricant inside the plastic container in a mist form, evenly covering the hinge surface of the protective door, thus lubricating the hinge and preventing rust. Furthermore, by setting a positioning cover and a sliding cover, after the protective door is closed, the sliding cover can slide out from the inside of the positioning cover, thereby shielding the hinge of the protective door and reducing the erosion of rainwater and dust. This solves the problems of existing anti-fall-off transformer shells not having an automatic lubrication structure for the door panel hinges during use, which easily leads to wear of the hinges after long-term use, resulting in difficulty in opening and closing the door and noise, and the lack of an external protective structure for the hinges during use, which cannot shield the hinges and makes them susceptible to erosion by rainwater and dust.

[0008] Preferably, a top cover is installed on the top surface of the protective shell, and a fixing seat is provided at each corner of the top surface of the top cover, with a lifting ring installed on the top surface of the fixing seat.

[0009] Preferably, symmetrical side plates are embedded on both the front and rear surfaces of the protective shell, and ventilation slots are opened through the front surface of the side plates. Fan positioning frames are installed on the side of the side plates inside the protective shell corresponding to the ventilation slots.

[0010] Preferably, two symmetrical fixing blocks are installed on both the left and right surfaces of the side plate, and positioning screws are installed on the front surface of the fixing blocks. The side plate is fixed to the protective shell by the positioning screws.

[0011] Preferably, internal support blocks are installed on all four sides of the inner surface of the protective shell, and two feet are installed on the bottom surface of the internal support blocks, with the sides of the feet fitting against the inner wall of the protective shell.

[0012] Preferably, a sealing gasket is provided on the bottom surface of the protective shell.

[0013] Preferably, a mounting frame is embedded in the right side wall of the protective shell, and multiple rain-proof blades are provided on the inner surface of the mounting frame.

[0014] Preferably, the mounting base and the top cover are fixed by welding, and the lifting ring and the mounting base are connected by threads.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting a pressure rod, the protective door can move synchronously with the pressure rod during opening. The pressure rod will gradually approach the push-type nozzle and press it, thereby spraying the lubricating liquid inside the plastic container in a mist form, which will evenly cover the hinge surface of the protective door. This will lubricate the hinge and prevent rust. This solves the problem that the existing anti-fall-off transformer shell does not have an automatic lubrication structure for the door hinge. After long-term use, the hinge is prone to wear, which leads to difficulty in opening and closing the door and noise.

[0017] 2. By setting a positioning cover and a sliding cover, after the protective door is closed, the sliding cover can slide out from the inside of the positioning cover, thereby covering the hinge of the protective door and providing protection for the hinge, reducing the erosion of rainwater and dust. This solves the problem that the existing anti-fall-off transformer shell does not have an external protective structure for the hinge during use, and cannot cover the hinge, making the hinge susceptible to erosion by rainwater and dust.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5This utility model provides an embodiment of an anti-detachment transformer housing, including a protective shell 1; it also includes a placement box 3, an observation slot 4, a plastic container 5, a press-type nozzle 6, a pressure rod 7, a positioning cover 9, a sliding cover 10, and a slider 11. The front surface of the protective shell 1 has two symmetrical protective doors 2 connected by hinges. A placement box 3 is provided on the front surface of the protective shell 1 at the positions corresponding to the four hinges. An observation slot 4 is provided on the front surface of the placement box 3. A plastic container 5 is placed inside the placement box 3. A press-type nozzle 6 is installed at the opening of the plastic container 5. A pressure rod 7 is provided on the front surface of each of the two protective doors 2 at the positions corresponding to the press-type nozzle 6. A latch 8 is provided in the middle of the front surface of the two protective doors 2. The front surface of the protective shell 1 corresponds to the anti-detachment... Positioning covers 9 are provided at the hinge positions of the protective door 2. A sliding cover 10 is provided on the inner surface of the positioning cover 9. Sliding blocks 11 are provided on the upper and lower surfaces of the sliding cover 10. The sliding cover 10 is slidably connected to the positioning cover 9 through the sliding blocks 11. By setting a pressure rod 7, when the protective door 2 is opened, the pressure rod 7 can be driven to move synchronously. After the pressure rod 7 moves to a certain distance, it will press the press-type nozzle 6, thereby spraying the lubricating liquid inside the plastic container 5 in a mist form, evenly covering the hinge surface of the protective door 2, thus lubricating the hinge and preventing rust. Furthermore, by setting the positioning cover 9 and the sliding cover 10, after the protective door 2 is closed, the sliding cover 10 can be slid out from the inside of the positioning cover 9, thereby shielding the hinge of the protective door 2 and reducing the corrosion of rainwater and dust.

[0026] Please see Figures 1-4 In this embodiment, a top cover 12 is installed on the top surface of the protective shell 1. A fixing seat 13 is provided at each corner of the top surface of the top cover 12. A lifting ring 14 is installed on the top surface of the fixing seat 13. By setting the fixing seat 13 and the lifting ring 14, it is easy to hoist the whole device and put it on the outside of the transformer. Symmetrical side plates 15 are embedded in the front and rear surfaces of the protective shell 1. A ventilation slot 16 is opened through the front surface of the side plate 15. A fan positioning frame 17 is installed on the side of the side plate 15 inside the protective shell 1, corresponding to the ventilation slot 16. By setting the side plate 15 and the fan positioning frame 17, space can be provided for the installation of the cooling fan. Two symmetrical fixing blocks 18 are installed on the left and right surfaces of the side plate 15. A positioning screw 19 is installed on the front surface of the fixing block 18. The side plate 15 is fixed to the protective shell 1 by the positioning screw 19. By setting the positioning screw 19, it is easy to install and fix the side plate 15, and it is also easy to disassemble the side plate 15 for maintenance of the internal transformer.

[0027] Please see Figures 1-4In this embodiment, inner support blocks 20 are installed on all four sides of the inner surface of the protective shell 1. Two support legs 21 are installed on the bottom surface of each inner support block 20, with the sides of the support legs 21 fitting against the inner wall of the protective shell 1. By providing the inner support blocks 20, the four sides of the protective shell 1 can be supported, reducing deformation. A sealing gasket 22 is provided on the bottom surface of the protective shell 1. The sealing gasket 22 improves the sealing effect with the ground, preventing water seepage. An installation frame 23 is embedded in the right side wall of the protective shell 1. The inner surface of the mounting frame 23 is provided with multiple rain-proof blades 24. By setting the mounting frame 23 and the rain-proof blades 24, the overall heat dissipation effect of the protective shell 1 can be improved, and the internal temperature can be prevented from being too high during use, which would cause the circuit to age. The fixing seat 13 and the top cover 12 are fixed by welding. The lifting ring 14 and the fixing seat 13 are connected by threads. By using the threaded connection to install and fix the lifting ring 14 and the fixing seat 13, it is easy to disassemble and install the lifting ring 14, so as to replace the lifting ring 14 of different sizes to adapt to the lifting operation.

[0028] During operation, the fixed base 13 and lifting ring 14 facilitate the overall hoisting of the device, allowing it to be fitted onto the outside of the transformer. The side plate 15 and fan positioning frame 17 provide space for the installation of the cooling fan. The positioning screws 19 facilitate the installation and fixation of the side plate 15, as well as its disassembly for internal transformer maintenance. The internal support block 20 provides support for the four sides of the protective shell 1, reducing deformation. The sealing gasket 22 improves the sealing effect with the ground, preventing water leakage. The mounting frame 23 and rainproof blades 24 enhance the overall heat dissipation of the protective shell 1, preventing excessive internal temperature from causing wiring aging during use. The threaded connection between the lifting ring 14 and the fixed base 13 facilitates the disassembly and replacement of the lifting ring 14 with different sizes to suit hoisting operations.

[0029] Through the above steps, by setting up the pressure rod 7, when the protective door 2 is opened, the pressure rod 7 can be driven to move synchronously. After the pressure rod 7 moves to a certain distance, it will press the press-type nozzle 6, thereby spraying the lubricant inside the plastic container 5 in a mist form, evenly covering the hinge surface of the protective door 2, thus lubricating the hinge and preventing rust. Furthermore, by setting up the positioning cover 9 and the sliding cover 10, after the protective door 2 is closed, the sliding cover 10 can slide out from the inside of the positioning cover 9, thereby shielding the hinge of the protective door 2 and reducing the erosion of rainwater and dust. This solves the problems of existing anti-fall-off transformer shells not having an automatic lubrication structure for the door panel hinges during use, which easily leads to wear and tear of the hinges after long-term use, resulting in difficulty in opening and closing the door and noise, as well as the lack of an external protective structure for the hinges during use, which cannot shield the hinges and makes them susceptible to erosion by rainwater and dust.
