Description
A transformer high and low voltage integrated cable box device Technical Field
[0001] This utility model relates to the field of cable installation and laying technology; more specifically, it relates to a transformer high and low voltage integrated cable box device. Background Technology
[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to convert AC voltage. It is widely used in power transmission, distribution and various electrical equipment. Its core function is to transmit electrical energy through two or more windings and complete the step-up or step-down operation. As a power device that combines economic and technical advantages, the transformer integrates high-voltage and low-voltage units into the same enclosure, which significantly reduces the installation space requirements. It is especially suitable for space-constrained scenarios such as cities. Therefore, it is often necessary to configure high and low voltage integrated cable box devices.
[0003] Currently, existing transformer high and low voltage integrated cable box devices have several drawbacks during use. Firstly, some existing devices rely on ventilation openings for internal heat dissipation. However, this method allows rainwater to enter the device through these openings, potentially affecting its waterproof performance. Secondly, many existing devices lack dustproof structures, allowing airborne dust to easily enter and contaminate the internal cables. Therefore, there is an urgent need for a transformer high and low voltage integrated cable box device to address these issues. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a transformer high and low voltage integrated cable box device to solve the problems existing in the background art.

[0006] The main structure includes a base, a cabinet structure, ventilation openings and sealing gaskets, and the ventilation openings are provided in two sets;
[0007] The protective structure includes a hinge and a sealing ring, and one end of the hinge is fixedly connected to the outer surface of one side of the cabinet structure.
[0008] The heat dissipation structure is provided in two sets, and the heat dissipation structure includes a waterproof box, an air inlet, a filter element and a fixing block. The two sets of waterproof boxes are respectively fixedly connected to the outer surfaces of both sides of the cabinet structure, and the interior of the two sets of waterproof boxes is connected to the interior of the two sets of air inlets.
[0009] Preferably, the cabinet structure is fixedly connected to the upper surface of the base, and a top cover is fixedly connected to the upper surface of the cabinet structure. The top cover is higher in the middle and lower on both sides, and the two sides of the top cover have an inclination angle of ≥10°. Therefore, rainwater can be quickly slid off by gravity, and water accumulation on the upper surface of the top cover can be minimized.
[0010] Preferably, the two sets of ventilation openings are respectively opened inside the outer surfaces on both sides of the cabinet structure, and the sealing gasket is fixedly connected to the front end of the inner surface of the cabinet structure. The sealing gasket is made of rubber.
[0011] Preferably, the other end of the hinge is fixedly connected to a protective door, the sealing ring is fixedly connected to the surface of one side of the protective door, and the surface of one side of the sealing ring and the surface of one side of the sealing gasket are in contact with each other. An observation window is fixedly connected inside the protective door, and a handle is fixedly connected to the surface of the other side of the protective door. By the contact between the sealing ring and the sealing gasket, the gap between the cabinet structure and the protective door can be filled as much as possible, thereby improving the waterproof sealing ability of the protective structure to a certain extent.
[0012] Preferably, the protective door is equipped with a door lock, and the front end of the cabinet structure is equipped with a door lock latch. The door lock and the door lock latch work together to lock the cabinet structure, thereby preventing unauthorized personnel from entering the interior of the cabinet structure.
[0013] Preferably, a cooling fan is installed inside one side of the waterproof box, the air inlet is fixedly connected to the lower end of the waterproof box, the filter element is inserted into the air inlet, and a connecting seat is fixedly connected to the outer surface of one end of the air inlet. An external power supply can provide power to the cooling fan, and the cooling fan can dissipate heat from the inside of the cabinet structure after it is started.
[0014] Preferably, a connecting plate is inserted into the interior of one side surface of the connecting seat, and a fixing block is fixedly connected to one end of the connecting plate. The surface of one side of the fixing block is attached to the outer surface of one end of the filter element. A spring is fixedly connected to one end of the fixing block, and one end of the spring abuts against the inner surface of the connecting seat. Air needs to pass through the air inlet and the filter element to enter the interior of the waterproof box. The filter element can intercept and filter dust and impurities in the air, thereby minimizing the entry of dust into the interior of the cabinet structure.
[0015] The technical effects and advantages of this utility model are as follows: By fitting the sealing ring and the sealing gasket together, this utility model can fill the gap between the cabinet structure and the protective door as much as possible, thereby improving the waterproof sealing ability of the protective structure to a certain extent. In addition, outside air needs to enter the interior of the waterproof box through the air inlet. The opening of the air inlet is vertically downward, so it can prevent rainwater from flowing into the interior of the air inlet. This design can effectively prevent rainwater from entering the interior of the cabinet structure.
[0016] The filter element can intercept and filter dust and impurities in the air, thus minimizing the entry of dust into the cabinet structure. Pulling the connecting plate can move the fixing block, causing it to no longer adhere to the outer surface of one end of the filter element. At this point, the filter element can be pulled out from inside the air inlet for cleaning. This design improves the dustproof capability of the equipment and makes it easier for staff to clean both sets of filter elements later. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The transformer high and low voltage integrated cable box device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Example 1
[0026] As shown in Figures 1 to 4, this utility model provides a transformer high and low voltage integrated cable box device, including: a main structure 1, which includes a base 11, a cabinet structure 12, ventilation openings 14, and sealing gaskets 15. The ventilation openings 14 are provided in two sets. The cabinet structure 12 is fixedly connected to the upper surface of the base 11, and a top cover 13 is fixedly connected to the upper surface of the cabinet structure 12. The top cover 13 is higher in the middle and lower on both sides. The two sets of ventilation openings 14 are respectively opened inside the outer surfaces on both sides of the cabinet structure 12. The sealing gaskets 15 are fixedly connected to the front end of the inner surface of the cabinet structure 12. The two sides of the top cover 13 have an inclination angle of ≥10°, so rainwater can be quickly slid off by gravity, which can minimize the accumulation of water on the upper surface of the top cover 13. The base 11 can reduce the impact of ground water on the interior of the cabinet structure 12 and minimize the penetration of rainwater into the interior of the cabinet structure 12, thereby improving the waterproof capability of the interior of the cabinet structure 12 to a certain extent.
[0027] Protective structure 2 includes a hinge 21 and a sealing ring 23. One end of the hinge 21 is fixedly connected to the outer surface of one side of the cabinet structure 12, and the other end of the hinge 21 is fixedly connected to a protective door 22. The sealing ring 23 is fixedly connected to the surface of one side of the protective door 22, and the surface of one side of the sealing ring 23 is in contact with the surface of one side of the sealing gasket 15. An observation window 24 is fixedly connected inside the protective door 22, and a handle 25 is fixedly connected to the surface of the other side of the protective door 22. A door lock is provided on the protective door 22, and a door latch is provided at the front end of the cabinet structure 12. The door lock and the door latch cooperate to lock the door. The sealing gasket 15 is made of rubber. Because rubber has good elasticity and sealing properties, the fit between the sealing ring 23 and the sealing gasket 15 can fill the gap when the cabinet structure 12 and the protective door 22 are fitted together, thereby improving the waterproof sealing ability of the protective structure 2 to a certain extent. The door lock and door latch work together to prevent unauthorized personnel from entering the interior of the cabinet structure 12. The observation window 24 allows staff to observe the interior of the cabinet structure 12 from the outside of the equipment. The handle 25 makes it easier for staff to open the protective door 22.
[0028] Example 2
[0029] As shown in Figures 1 to 6, this embodiment also proposes a heat dissipation structure 3, which has two sets. The heat dissipation structure 3 includes a waterproof box 31, an air inlet 33, a filter element 34, and a fixing block 37. The two sets of waterproof boxes 31 are respectively fixedly connected to the outer surfaces of both sides of the cabinet structure 12. The interiors of the two sets of waterproof boxes 31 are respectively connected to the interiors of the two sets of ventilation openings 14. A cooling fan 32 is installed inside one side of the waterproof box 31. The air inlet 33 is fixedly connected to the lower end of the waterproof box 31, and the filter element 34 is inserted into the interior of the air inlet 33. A connecting seat 35 is fixedly connected to the outer surface of one end of the air inlet 33. A connecting plate 36 is inserted into the interior of one side surface of the connecting seat 35, and a fixing block 37 is fixedly connected to one end of the connecting plate 36. The surface of one side of the fixing block 37 is attached to the outer surface of one end of the filter element 34. A spring 38 is fixedly connected to one end of the fixing block 37, and one end of the spring 38 abuts against the inner surface of the connecting seat 35. The upper surface of the waterproof box 31 has a large inclination, which can prevent rainwater from accumulating on the upper surface of the waterproof box 31, and the outside air needs to be... Air must pass through inlet 33 to enter the interior of the waterproof box 31. The opening of inlet 33 is vertically downward, thus preventing rainwater from flowing into the interior of inlet 33. This design prevents rainwater from entering the interior of the cabinet structure 12. An external power supply can provide power to the cooling fan 32. After the cooling fan 32 is started, it can dissipate heat from the interior of the cabinet structure 12. Air must pass through inlet 33 and filter element 34 to enter the interior of the waterproof box 31. Filter element 34 can intercept and filter dust and impurities in the air, thereby minimizing the entry of dust into the interior of the cabinet structure 12. Pulling the connecting plate 36 can move the fixing block 37 and cause the fixing block 37 to no longer adhere to the outer surface of one end of the filter element 34. At this time, the filter element 34 can be pulled out from the interior of inlet 33 for cleaning. This design can improve the dustproof capability of the equipment and make it easier for staff to clean the two sets of filter elements 34 later. After releasing the connecting plate 36, the spring 38 can use its own elasticity to push the fixing block 37 to reset.
[0030] Working principle: When the equipment is in use, the sealing ring 23 and the sealing gasket 15 can fill the gap when the cabinet structure 12 and the protective door 22 are fitted together as much as possible, thereby preventing rainwater from entering the interior of the cabinet structure 12 through the protective door 22. First, two sets of cooling fans 32 are started to dissipate heat from the interior of the cabinet structure 12. Air needs to pass through the air inlet 33 and the filter element 34 before entering the interior of the waterproof box 31. Then, the filter element 34 can intercept and filter dust and impurities in the air.
[0031] When the filter element 34 needs to be cleaned or replaced, first pull the connecting plate 36 to move the fixing block 37. Then the fixing block 37 is no longer attached to the outer surface of one end of the filter element 34. At this time, the staff can pull the filter element 34 out of the air inlet 33 for cleaning. The above is the whole working principle of this utility model. (The cooling fan 32 used in this application is a product that can be purchased directly on the market. Its principle, connection method and control method are all existing technologies known to those skilled in the art, so they will not be described in detail here.)
