Description

Technical Field

[0001] This invention relates to the field of transformer box technology, and in particular to a transformer box leakage prevention, safety heat dissipation and insulation device. Background Technology

[0002] The transformer enclosure usually refers to the iron outer shell of an oil-immersed transformer. Its formal name is "transformer oil tank". It is welded from a cylinder plate and is a component of the transformer body. It houses the iron core and windings and is filled with insulating oil. It plays a key role in mechanical support, insulation, heat dissipation and protection of internal components. It is not an external protective enclosure.

[0003] Currently, most transformer box heat dissipation and protection devices on the market use fixed louvered structures for their ventilation openings. Under normal operating conditions, these structures can take into account both ventilation and basic protection. However, when encountering severe weather such as strong winds and rain, this type of structure faces an inherent technical contradiction: if the louvers are closed to maintain protection, the heat dissipation channel is blocked, internal heat accumulates, and a safety hazard is created. Summary of the Invention

[0004] In view of the problem that the above-mentioned or existing technologies cannot effectively protect the device from heat dissipation, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a transformer box anti-leakage safety heat dissipation and insulation device, including a main body, a housing disposed on both sides of the main body, a closing assembly disposed on the front of the housing, and a ventilation assembly disposed on both sides of the housing;

[0006] The closing assembly includes an injection element and a closing element disposed on one side of the bottom of the injection element;

[0007] The ventilation assembly includes a side seat, a filter element is disposed inside the side seat, the filter element includes an opening and closing plate, and an adjustment element is disposed on one side of the filter element;

[0008] The adjusting component includes a moving plate and a slide groove. A filter plate is provided on one outer wall of the moving plate, and corrugated rods are provided on both sides of the moving plate. A linkage sleeve is provided outside the corrugated rods, a connecting rod is provided on one side of the linkage sleeve, a cam is provided on one side of the connecting rod, and a rotating rod is provided inside the cam.

[0009] Through the movement of the opening and closing plate, the rotating rod can rotate by sliding connection with the slide groove. The rotating rod drives the connecting rod and the linkage sleeve to move by the cam. The linkage sleeve can drive the moving plate to move by the corrugated rod to achieve the action of changing function.

[0010] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, the filter element includes a horizontal plate, which is disposed inside the side seat and is distributed in an equidistant vertical structure.

[0011] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, wherein: a mesh plate is provided between the horizontal plates, and the mesh plates are distributed in a corresponding structure.

[0012] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, the filter element further includes an injection seat, and a moving rod is slidably connected inside the injection seat.

[0013] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, wherein: one end of the moving rod is provided with a meshing bar, and one end of the opening and closing plate is provided with a meshing wheel that meshes with the meshing bar.

[0014] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, the injection component includes a telescopic cylinder, a mounting seat is provided on one side of the telescopic cylinder, and a piston plate is slidably connected inside the mounting seat.

[0015] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, wherein: the mounting base is provided with conduits on both sides that are connected to the injection base.

[0016] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, the closing member includes a piston sleeve, which is disposed on the front side of the housing.

[0017] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, wherein: a piston rod is slidably connected inside the piston sleeve, and a rack is provided at the bottom end of the piston rod.

[0018] As a preferred embodiment of the transformer box anti-leakage safety heat dissipation and insulation device of the present invention, the closing member further includes a baffle plate, and gears are movably mounted on both sides of the baffle plate through a rotating shaft, and the rack and gears mesh with each other.

[0019] The beneficial effects of this invention are as follows: The ventilation component, through the operation of its internal adjusting parts, allows the moving plate to rotate under normal weather conditions, thus facilitating heat dissipation through the filter plate and ensuring sufficient air convection for the transformer under normal operating conditions. However, in severe weather conditions such as strong winds or heavy rain, the opening of the opening and closing plate, accompanied by the reverse rotation of the moving plate, causes the reverse plate to extend outward and form a "wind-gathering hood" structure. This hood actively captures and gathers high-speed external airflow, guiding air to circulate rapidly from the inside of the device in a through-draft manner, thereby achieving forced convection cooling using strong winds in severe weather. While the front louvers are closed to prevent rain, they also maintain effective heat dissipation. At the same time, the mesh plate effectively prevents horizontal intrusion of rainwater and the entry of dust and debris, achieving a balance between protection and heat dissipation. Furthermore, through the coordinated design of the injection and closing components in the closing assembly, the baffle plate can move synchronously with the movement of the moving plate under normal weather conditions, while closing in conjunction with the reverse plate under severe weather conditions. This effectively prevents the intrusion of garbage, impurities, and even rainwater under severe weather conditions, while maintaining the filter plate in the correct position under normal weather conditions, thus providing continuous heat dissipation. This avoids the technical contradiction of existing devices that cannot balance protection and heat dissipation under severe weather conditions. Attached Figure Description

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figures 1 to 5 This is the first embodiment of the present invention. This embodiment provides a transformer box anti-leakage safety heat dissipation and insulation device that can achieve automatic switching. It includes a main body 1, a shell 2 disposed on both sides of the main body 1, a closing component 3 disposed on the front of the shell 2, and a ventilation component 4 disposed on both sides of the shell 2. The main body 1 is a transformer box, which plays a role in protecting the internal parts of the transformer. The shell 2 can be used to protect the heat dissipation fins contained in the transformer box 1. The closing component 3 can adjust the state of the device, and the ventilation component 4 improves the ventilation and adjustment functions of the device.

[0034] The closing component 3 includes an injection component 31 and a closing component 32 disposed on one side of the bottom of the injection component 31. The injection component 31 can provide power for the operation of the closing component 32. The top of the housing 2 is provided with a wind and rain sensor connected to the injection component 31. The wind and rain sensor can detect wind volume and rainfall to detect whether it is severe weather.

[0035] The ventilation assembly 4 includes a side seat 41, and a filter element 42 is provided inside the side seat 41. The filter element 42 includes an opening and closing plate 423. An adjustment element 43 is provided on one side of the filter element 42. The filter element 42 can perform the function of switching functions, while the adjustment element 43 can effectively adjust the angle of the opening and closing plate 423.

[0036] The adjusting component 43 includes a moving plate 431 and a sliding groove 438. A filter plate 432 is provided on one outer wall of the moving plate 431. Corrugated rods 433 are provided on both sides of the moving plate 431. A linkage sleeve 437 is provided outside the corrugated rods 433. A connecting rod 436 is provided on one side of the linkage sleeve 437. A cam 435 is provided on one side of the connecting rod 436. A rotating rod 434 is provided inside the cam 435. The sliding groove 438 and the rotating rod 434 are slidably connected. Therefore, when the opening and closing plate 423 moves, the opening... The hinge plate 423 can be slidably connected with the rotating rod 434 and the slide groove 438, so that the rotating rod 434 can be effectively rotated. The moving plate 431 has an L-shaped structure, with a filter plate 432 on one side and no filter plate 432 on the other side. The opening and closing plate 423 has only two adjustable angles. The first angle is the closed angle. At the first angle, the moving plate 431 will make the filter plate 432 perpendicular to the ground under the action of the cam 435 and the connecting rod 436. At the second opening angle, the filter plate 432 is horizontal to the ground.

[0037] Through the movement of the opening and closing plate 423, the rotating rod 434 can rotate by sliding connection with the slide groove 438. The rotating rod 434 drives the connecting rod 436 and the linkage sleeve 437 to move by the cam 435. The linkage sleeve 437 can drive the moving plate 431 to move by the corrugated rod to achieve the action of changing function.

[0038] Specifically, the filter element 42 includes a horizontal plate 421, which is disposed inside the side seat 41. The horizontal plate 421 is distributed vertically at equal intervals and is installed inside the side seat 41 by bolts. Its distribution position corresponds to the heat dissipation fins on both sides of the main body 1. The heat dissipation fins of the main body 1 are also horizontal to the ground. The horizontal plate 421 is inclined at the top. This structure can effectively guide rainwater and prevent rainwater from entering the interior of the device.

[0039] Among them, a mesh plate 422 is provided between the horizontal plates 421. The mesh plates 422 are distributed in a corresponding structure. The mesh plate 422 can effectively prevent rainwater from entering. Since the same structure is provided on both sides of the device, and the wind direction is not always flowing in the same direction, when the wind flows in the opposite direction, the dust on the surface of the filter plate 432 can also be cleaned.

[0040] Preferably, the filter element 42 further includes an injection seat 424, and a moving rod 425 is slidably connected inside the injection seat 424. The injection seat 424 has a hollow structure and is filled with hydraulic oil. The moving rod 425 slides inside the injection seat 424. Therefore, when the hydraulic oil is continuously injected, the hydraulic oil can push the moving rod 425 to move.

[0041] It should be noted that one end of the moving rod 425 is provided with a meshing bar 426, and one end of the opening and closing plate 423 is provided with a meshing wheel 427 that meshes with the meshing bar 426. The meshing wheel 427 is connected to the moving rod 425. Therefore, when the moving rod 425 moves, the moving rod 425 can drive the meshing bar 426 to move, and the meshing bar 426 meshes with the meshing wheel 427. The meshing wheel 427 is fixed to the top of the opening and closing plate 423, so it can drive the opening and closing plate 423 to rotate.

[0042] In use, when hydraulic oil is injected into the injection seat 424, the hydraulic oil drives the moving rod 425 to move. During the movement of the moving rod 425, the moving rod 425 drives the meshing bar 426 to move. During the movement of the meshing bar 426, the meshing bar 426 can mesh with the meshing wheel 427, causing the meshing wheel 427 to move. The meshing wheel 427 can drive the opening and closing plate 423 to move. During the opening and closing of the opening and closing plate 423, the opening and closing plate 423 can synchronously drive the rotating rod 434 to move. The rotating rod 434 can slide through the slide groove 438, causing the rotating rod 434 to move. The rotating rod 434 can drive the fixed cam 435. The connection allows the cam 435 to rotate. The cam 435 is movably connected to the connecting rod 436, which in turn drives the linkage sleeve 437 to move. The linkage sleeve 437 is slidably connected to the bellows rod 433 via the spiral groove on its outer wall, causing the bellows rod 433 to rotate. The bellows rod 433 then drives the moving plate 431 to rotate. When fully open, the moving plate 431 rotates 90 degrees, making the filter plate 432 perpendicular to the ground. This allows airflow to pass through the opening and closing plate 423 and the moving plate 431, converging the airflow in a funnel shape. This allows the airflow to pass quickly through the device in strong winds or other severe weather conditions.

[0043] In summary, through the movement plate 431 and the rotation of the opening and closing plate 423, the opening and closing plate 423 can utilize the sliding connection between the rotating rod 434 and the slide groove 438 to enable the rotating rod 434 to drive the cam 435 to rotate. The cam 435 can then drive the linkage sleeve 437 to move via the connecting rod 436. The linkage sleeve 437 can utilize the sliding connection with the corrugated rod 433 to allow the movement plate 431 to present two angles when the opening and closing plate 423 is open and closed. When closed, the filter plate 432 can be effectively used for filtration, while when open, the airflow can be effectively guided.

[0044] Example 2, refer to Figure 1 , Figure 2 and Figure 8 This is the second embodiment of the present invention. Unlike the previous embodiment, it solves the problem of synchronous operation of the opening and closing plate and the blocking plate.

[0045] Specifically, the injection component 31 includes a telescopic cylinder 311, a mounting base 312 is provided on one side of the telescopic cylinder 311, a piston plate 313 is slidably connected inside the mounting base 312, the telescopic cylinder 311 is installed in a groove on the top of the housing 2 by bolts, the mounting base 312 is filled with hydraulic oil, and the piston plate 313 slides inside the mounting base 312, the output end of the telescopic cylinder 311 is connected to the piston plate 313.

[0046] Furthermore, the mounting base 312 is provided with conduits 314 that communicate with the injection base 424 on both sides. The conduits 314 are installed on both sides of the mounting base 312 by bolts, and the front of the mounting base is also provided with conduits 314. The conduits 314 are connected to the closure member 32 and the filter member 42.

[0047] The rest of the structure is the same as in Example 1.

[0048] In use, the telescopic cylinder 311 in the groove at the top of the housing 2 is activated. The telescopic cylinder 311 pushes the piston plate 313 to slide linearly along the inner wall of the mounting base 312. A hydraulic chamber with sealed sides is formed between the piston plate 313 and the mounting base 312. The chamber is filled with hydraulic oil. The piston plate 313 acts as a bidirectional pushing component. When it moves, it can simultaneously squeeze the hydraulic oil on both sides. The conduit 314 is connected to the filter element 42 and the closing element 32 respectively. The hydraulic oil flows directionally in the conduit 314, synchronously transmitting the output power of the telescopic cylinder 311 to the filter element 42 and the closing element 32, so that both can act simultaneously. With the above settings, when the telescopic cylinder 311 moves the piston plate 313, the filter element 42 and the closing element 32 can achieve synchronous linkage through the hydraulic transmission of hydraulic oil on both sides and the conduit 314. This ensures that the opening and closing plate 423 also operates synchronously when the baffle plate 325 is opened, so that the closing component 3 and the ventilation component 4 operate in coordination. This hydraulic synchronous drive method ensures that a reliable seal is formed between the closing element 32 and the ventilation component 4 when the closing element 32 is closed, avoiding the leakage of airflow from an unexpected path due to poor sealing, which would damage the pressure difference conditions required for the through-draft, thus ensuring the formation effect of the through-draft under severe weather conditions.

[0049] In summary, by using the telescopic cylinder 311, when the telescopic cylinder 311 moves the piston plate 313, the piston plate 313, through the hydraulic transmission of hydraulic oil on both sides and the conduit 314, enables the filter element 42 and the closing element 32 to operate synchronously. This achieves linkage without the need for an additional independent drive source. Therefore, the opening and closing plate 423 can also operate when the baffle plate 325 is opened. This design ensures the coordinated operation of the closing component 3 and the ventilation component 4, and avoids air leakage due to poor sealing, which would disrupt the pressure difference conditions required for cross ventilation and affect the formation of cross ventilation. This design allows the device to effectively cool the heat dissipation fins.

[0050] Example 3, referring to Figures 2 to 7 This is the third embodiment of the present invention. Unlike the previous embodiment, it solves the problem of heat dissipation of the device, and includes [the following].

[0051] Specifically, the closure 32 includes a piston sleeve 321, which is disposed on both sides of the front of the housing 2. The piston sleeve 321 is installed in the grooves on both sides of the front of the housing 2 by bolts, and the piston sleeve 321 is in communication with the conduit 314.

[0052] Furthermore, a piston rod 322 is slidably connected inside the piston sleeve 321. A rack 323 is provided at the bottom end of the piston rod 322. The piston rod 322 is slidably connected inside the piston sleeve 321, and the rack 323 is bolted to one end of the piston rod 322. The piston sleeve 321 and the piston rod 322 slide in close contact.

[0053] The closure 32 also includes a baffle plate 325. Gears 324 are movably mounted on both sides of the baffle plate 325 via a rotating shaft. The rack 323 meshes with the gears 324. The baffle plate 325 is movably mounted in the groove on the front of the housing 2 via a rotating shaft. Gears 324 are mounted on both sides of the baffle plate 325 via bolts. The gears 324 are movably connected to the housing 2. The gears 324 and the rack 323 mesh with each other via teeth.

[0054] The rest of the structure is the same as in Example 2.

[0055] During use, hydraulic oil is injected into the piston sleeve 321 through the conduit 314. As the hydraulic oil is continuously injected, the piston rod 322 moves downward under hydraulic pressure. The piston rod 322 is fixedly connected to the rack 323, so the rack 323 moves downward synchronously and drives the gear 324 to rotate through the meshing of the teeth of the gear 324. The gear 324 is fixedly connected to the baffle plate 325. When the gear 324 rotates, the baffle plate 325 rotates and opens accordingly, keeping the device in a ventilated state under normal weather conditions without affecting heat dissipation. Through the set closing component 3, the sliding cooperation between the piston sleeve 321 and the piston rod 322 in the closing component 32 drives the rack 323 and the gear 324 to rotate, thereby controlling the movement of the baffle plate 325. Under normal weather conditions, the baffle plate 325 can effectively dissipate heat from the heat dissipation fins of the main body 1. At the same time, its structure can block the entry of external garbage and debris, protecting the fins and improving the overall performance of the device. Under severe weather conditions, the baffle plate 325 will close to prevent rainwater and garbage from entering the interior of the device.

[0056] In summary, through the closure component 3, the sliding engagement between the piston sleeve 321 and the piston rod 322 in the closure component 32 drives the rack 323 and gear 324 to rotate, thereby driving the baffle plate 325 to move. The entire transmission process is achieved hydraulically, without the need for additional electric drive. Under normal weather conditions, the baffle plate 325 can effectively dissipate heat from the heat dissipation fins of the main body 1 while preventing external debris from entering, thus protecting the fins and improving the effectiveness of the device. Under severe weather conditions, the baffle plate 325 changes, effectively protecting the main body 1.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
