Description

Technical Field

[0001] This utility model relates to the field of prefabricated transformer substation technology, and in particular to a prefabricated prefabricated transformer substation with airflow circulation cooling. Background Technology

[0002] Prefabricated box-type substations (referred to as "box-type substations") are compact, complete sets of power distribution equipment that combine high-voltage switchgear, distribution transformers, low-voltage switchgear, power metering equipment, and reactive power compensation devices within a box according to a specific main wiring scheme. They possess significant advantages such as compact structure, small footprint, convenient installation, low investment, short construction period, strong environmental adaptability, and portability. They are widely used in urban power grid upgrades, residential communities, commercial centers, industrial and mining enterprises, wind and photovoltaic power stations, and other locations, becoming key node equipment in modern power distribution network systems.

[0003] Prefabricated box-type substations on the market do not easily dissipate the heat generated during workload and long-term use, which accumulates inside and affects the normal operation of the equipment. At the same time, when the working environment temperature inside the box is high, the internal temperature of the box will rise rapidly, resulting in excessively high internal temperature. If the operator forgets to open the ventilation windows inside the box, it can easily affect the operation of the electrical equipment inside the box, shorten the service life of the box-type substation, and even cause a fire. To address these issues, we provide a prefabricated box-type substation with airflow circulation cooling to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a prefabricated box-type transformer with airflow circulation cooling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A prefabricated box-type transformer with airflow circulation cooling includes a box body, a box door movably connected to the front of the box body, ventilation windows on both sides of the box body, a sealing mechanism fixedly installed at the ventilation window of the box body, and a cooling fan fixedly installed inside the sealing mechanism. The sealing mechanism includes two side strips, both of which are fixedly connected to the housing. A horizontal plate is fixedly connected to the bottom of each side strip, and side mounting plates are fixedly connected to both sides of the upper surface of the horizontal plate. A geared motor is fixedly installed on the outer wall of the side mounting plate. A first movable strip is fixedly connected to the output end of the geared motor. A first sealing plate is fixedly connected to the upper surface of the first movable strip. A connecting rod is rotatably connected to the other end of the first movable strip, and a second movable strip is rotatably connected to the other end of the connecting rod. One end of the second movable strip is rotatably connected to the side strip, and a second sealing plate is fixedly connected to the outer wall of the second movable strip.

[0006] Preferably, the length of the second sealing plate is much greater than the length of the first sealing plate.

[0007] Preferably, there are two of each of the first movable strip, the connecting rod, and the second movable strip. The two first movable strips are located on both sides of the lower surface of the first sealing plate, and the two second movable strips are located on both sides of the lower surface of the second sealing plate.

[0008] Preferably, a lower limit baffle is fixedly connected to the upper surface of the horizontal plate, and a first rubber block is fixedly connected to the outer wall of the lower limit baffle, the first rubber block corresponding to the first sealing plate; An upper limit baffle is fixedly connected to the outer wall of the side mounting plate, and a second rubber block is fixedly connected to the outer wall of the upper limit baffle. The second rubber block corresponds to the second sealing plate.

[0009] Preferably, a terminal block is fixedly installed on the outer wall of the side mounting plate, and the terminal block is electrically connected to the geared motor.

[0010] Preferably, a connecting rod is fixedly connected to the top of the side strip, and a mounting ring is fixedly connected to the other end of the connecting rod. The bottom of the mounting ring is fixedly connected to the side wall of the side mounting plate, and the outer wall of the mounting ring is fixedly connected to the cooling fan by screws.

[0012] Preferably, four lifting rings are fixedly installed on the top of the box, and the four lifting rings are located at the four corners of the top of the box.

[0013] The beneficial effects of this utility model are as follows: 1. In this utility model, when the internal temperature of the box is too high, the temperature sensor can detect that the internal temperature of the box is too high. The temperature sensor controls the geared motor through the microcontroller. The geared motor drives the first movable strip to rotate clockwise. The first movable strip drives the first sealing plate to flip. At the same time, the first movable strip drives the second movable strip to rotate clockwise through the connecting rod. The second movable strip drives the second sealing plate to flip. At this time, the second sealing plate and the first sealing plate are in a horizontal state. The second sealing plate and the first sealing plate are perpendicular to the side strip. The ventilation window can be opened without manual operation, so that the high temperature gas inside the box can be discharged to the outside through the ventilation window.

[0014] 2. In this utility model, the external gas is drawn into the box from the bottom right side by a cooling fan, and the hot gas is discharged from the top left side, thereby improving the airflow circulation of the box. No manual operation is required, ensuring that the high-temperature gas inside the box is discharged to the outside through the ventilation window, while the external cooling gas enters the box through the ventilation window on the other side.

[0015] 3. In this utility model, when the second sealing plate and the first sealing plate are placed vertically, the ventilation window is sealed by the cooperation of the second sealing plate and the first sealing plate, which can prevent external dust and rainwater from entering the interior of the box and affecting the service life of the electrical equipment inside the box.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example: As attached Figure 1 To be continued Figure 9 As shown: A prefabricated box-type transformer with airflow circulation cooling includes a box body 1. A box door 2 is movably connected to the front of the box body 1. Ventilation windows 3 are opened on both sides of the box body 1. A sealing mechanism 4 is fixedly installed on the box body 1 at the ventilation window 3. A cooling fan 5 is fixedly installed on the inner side of the sealing mechanism 4. The sealing mechanism 4 includes two side strips 401, both of which are fixedly connected to the housing 1. A horizontal plate 402 is fixedly connected to the bottom of the side strip 401. Side mounting plates 403 are fixedly connected to both sides of the upper surface of the horizontal plate 402. A geared motor 404 is fixedly installed on the outer wall of the side mounting plate 403. A first movable strip 406 is fixedly connected to the output end of the geared motor 404. A first sealing plate 407 is fixedly connected to the upper surface of the first movable strip 406. A connecting rod 408 is rotatably connected to the other end of the first movable strip 406. A second movable strip 409 is rotatably connected to the other end of the connecting rod 408. One end of the second movable strip 409 is rotatably connected to the side strip 401. A second sealing plate 410 is fixedly connected to the outer wall of the second movable strip 409.

[0028] It is worth mentioning that the ventilation window 3 on the left side of the box 1 is opened at the top of the box 1. The top ventilation window 3 is used to exhaust hot air, and the ventilation window 3 on the right side of the box 1 is opened at the bottom of the box 1. The bottom ventilation window 3 is used to draw in cold air, thereby realizing gas circulation. The length of the second sealing plate 410 is much larger than that of the first sealing plate 407; there are two first movable strips 406, two connecting rods 408, and two second movable strips 409. The two first movable strips 406 are located on both sides of the lower surface of the first sealing plate 407, and the two second movable strips 409 are located on both sides of the lower surface of the second sealing plate 410.

[0029] In the above technical solution, the second sealing plate 410 and the first sealing plate 407 face outwards. When the second sealing plate 410 and the first sealing plate 407 are in the open state, it is not easy for external rainwater to enter the interior of the box 1.

[0030] A lower limit baffle 411 is fixedly connected to the upper surface of the horizontal plate 402. A first rubber block 412 is fixedly connected to the outer wall of the lower limit baffle 411. The first rubber block 412 corresponds to the first sealing plate 407. An upper limit baffle 413 is fixedly connected to the outer wall of the side mounting plate 403. A second rubber block 414 is fixedly connected to the outer wall of the upper limit baffle 413. The second rubber block 414 corresponds to the second sealing plate 410.

[0031] In the above technical solution, when the second sealing plate 410 and the first sealing plate 407 contract to close the ventilation window 3, the second sealing plate 410 contacts the second rubber block 414, and the first sealing plate 407 contacts the first rubber block 412.

[0032] A terminal block 405 is fixedly installed on the outer wall of the side mounting plate 403, and the terminal block 405 is electrically connected to the geared motor 404. A connecting rod 8 is fixedly connected to the top of the side strip 401, and a mounting ring 9 is fixedly connected to the other end of the connecting rod 8. The bottom of the mounting ring 9 is fixedly connected to the side wall of the side mounting plate 403, and the outer wall of the mounting ring 9 is fixedly connected to the cooling fan 5 by screws. The cooling fan 5 is electrically connected to the terminal block 405.

[0033] It is worth mentioning that the cooling fan 5 located on the left side of the cabinet 1 is installed in the opposite direction to the cooling fan 5 located on the right side of the cabinet 1. The cooling fan 5 located on the left side of the cabinet 1 is an exhaust fan, used to expel the hot air inside the cabinet 1, while the cooling fan 5 located on the right side of the cabinet 1 is an intake fan, used to draw the cold air from outside into the cabinet 1. In the above technical solution, the microcontroller 10 simultaneously controls the cooling fan 5 to start, and the cooling fan 5 draws the outside air into the box 1 from the bottom right side, and the hot air is discharged from the top left side, thereby improving the airflow circulation of the box 1. No manual operation is required, ensuring that the high-temperature air inside the box 1 is discharged to the outside through the ventilation window 3, while the external cooling air enters the box 1 through the ventilation window 3 on the other side.

[0034] A temperature sensor 7 and a microcontroller 10 are fixedly installed on the top inner wall of the enclosure 1. The temperature sensor 7 is electrically connected to the microcontroller 10, and the microcontroller 10 is electrically connected to the terminal block 405.

[0035] In the above technical solution, when the internal temperature of the enclosure 1 is too high, the temperature sensor 7 can detect that the internal temperature of the enclosure 1 is too high, and the temperature sensor 7 controls the geared motor 404 and the cooling fan 5 to work through the microcontroller 10.

[0036] It should be understood that the geared motor 404, cooling fan 5, temperature sensor 7, and microcontroller 10 mentioned in this article can all be conventional products in the prior art, and are all purchased from the market. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be repeated in the specification. For example, the microcontroller 10 can be the MSC1211Y5 microprocessor from Texas Instruments, USA, and the temperature sensor 7 can be the TS105 sensor produced by HLPlanar.

[0037] Four lifting rings 6 are fixedly installed on the top of the box 1. The four lifting rings 6 are located at the four corners of the top of the box 1, which facilitates the lifting, transportation and installation of the box 1.

[0038] In the above technical solutions, The specific usage and function of this embodiment are as follows: When this utility model is in use, in the initial state, the second sealing plate 410 and the first sealing plate 407 are placed vertically. The second sealing plate 410 and the first sealing plate 407 work together to seal the ventilation window 3, which can prevent external dust and rainwater from entering the interior of the box 1 and affecting the service life of the electrical equipment inside the box 1. When the internal temperature of the enclosure 1 is too high, the temperature sensor 7 can detect that the internal temperature of the enclosure 1 is too high. The temperature sensor 7 controls the geared motor 404 through the microcontroller 10. The geared motor 404 drives the first movable bar 406 to rotate clockwise. The first movable bar 406 drives the first sealing plate 407 to flip. At the same time, the first movable bar 406 drives the second movable bar 409 to rotate clockwise through the connecting rod 408. The second movable bar 409 drives the second sealing plate 410 to flip. At this time, the second sealing plate 410 and the first sealing plate 407 are in a horizontal state and the second sealing plate 410 and the first sealing plate 407 are perpendicular to the side bar 401. At the same time, the microcontroller 10 controls the cooling fan 5 to start, and the cooling fan 5 draws the outside air into the box 1 from the bottom right side, and the hot air is discharged from the top left side, thereby improving the airflow circulation of the box 1. No manual operation is required, and the high-temperature air inside the box 1 is discharged to the outside through the ventilation window 3. Meanwhile, the external cooling air enters the box 1 through the ventilation window 3 on the other side.
