Description

Technical Field

[0001] The utility model relates to the technical field of substation enclosures, in particular to a reinforced box-type substation enclosure. Background Technique

[0002] A box-type substation, also called a prefabricated substation or a prefabricated transformer substation, is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device. It is a factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme, that is, functions such as transformer step-down and low-voltage power distribution are organically combined together and installed in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. It is especially suitable for urban network construction and transformation and is a brand-new substation that emerged after the civil substation. The box-type substation is suitable for mines, factories and enterprises, oil and gas fields, and wind power stations. It replaces the original civil power distribution room and substation and becomes a new type of complete power transformation and distribution device.

[0003] The existing movement of the substation enclosure is only carried out through the pulleys at the lower end. However, the existence of the pulleys will cause the substation enclosure to easily slide relative to the ground during operation, and the heat dissipation effect of the substation enclosure on the transformer is limited. The transformer is prone to accumulate heat inside the substation enclosure, resulting in a reduced service life of the transformer. Moreover, the door cannot be air-dried, so the service life of the door cannot be guaranteed, and the use limitations are relatively large. In addition, the fire-proof effect is also poor, which is not conducive to use. Therefore, we propose a reinforced box-type substation enclosure. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a reinforced box-type substation enclosure, which plays a role in hindering the movement of the moving wheels and solves the problem that the substation enclosure is prone to relative sliding with the ground during operation. It can facilitate the efficient heat dissipation and cooling of the transformer inside the substation enclosure, avoid the ineffective discharge of the heat accumulated inside the transformer during high-power operation, and thus affect the service life of the transformer. It can effectively solve the problems in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A reinforced box-type substation enclosure, including an upper housing and a lower housing;

[0006] Connecting frames are symmetrically arranged at the upper and lower ends of the upper housing. Assembly units are symmetrically arranged at both ends of the connecting frames. The upper connecting frame is fixedly connected to the top cover, and the lower connecting frame is fixedly connected to the upper end of the lower housing. Heat dissipation openings are symmetrically opened at both ends of the upper housing. A sealing door is hinged to the front end of the upper housing. Moving wheels are evenly arranged at the four corners of the lower end of the lower housing. Anti-slip units are arranged at both ends of the moving wheels. An air-drying unit is arranged inside the sealing door;

[0007] The anti-slip unit includes a driving motor I, a fixing plate and a threaded rod. Connecting columns are fixedly installed at the four corners of the lower end of the lower housing. The lower ends of the connecting columns are fixedly connected to the moving wheels. Fixing plates are arranged on both sides of the moving wheels. The fixing plates are fixedly connected to the lower end of the lower housing. A threaded rod is rotatably connected between the fixing plates. The threaded rod passes through the connecting column and is threadedly connected to the connecting column. A driving motor I is fixedly installed at the outer end of one fixing plate. The output shaft of the driving motor I passes through the fixing plate and is fixedly connected to the threaded rod. Moving plates are threadedly connected to both ends of the threaded rod. The upper ends of the moving plates are slidably connected to the lower end of the lower housing. The lower ends of the moving plates are fixedly connected to the mounting seats. Anti-slip wheels are fixedly installed in the mounting seats.

[0008] Among them: the input ends of all driving motors are electrically connected to the output end of an external controller.

[0009] After the substation housing is placed well, the driving motor I can drive the threaded rod to rotate. Positive threads and reverse threads are respectively arranged at the left and right ends of the threaded rod. The rotation of the threaded rod drives the moving plates to move, drives the anti-slip wheels to move, so that the braking wheels gradually approach the moving wheels, which plays a role in hindering the movement of the moving wheels. Through the setting of the anti-slip unit, it plays a role in hindering the movement of the moving wheels, and solves the problem that the substation housing is prone to relative sliding with the ground during operation.

[0010] Furthermore, the assembling unit includes an assembling plate, assembling blocks and clamping blocks. Slots are opened at both ends of the connecting frame and the upper housing. Assembling blocks are inserted into the slots. One end of the assembling block is fixedly connected to the assembling plate. Clamping blocks are symmetrically arranged at the other end of the assembling block. Square grooves are symmetrically opened at the other end of the assembling block. The clamping blocks are slidably connected to the inner walls of the square grooves. Expansion rods are fixedly installed in the square grooves. The expansion rods are fixedly connected to the clamping blocks. Springs are sleeved on the expansion rods.

[0011] Through the setting of the assembling unit, it is convenient to assemble the substation housing, and at the same time, it is convenient to disassemble the top cover and the lower housing, avoiding the problem that it is inconvenient to repair the substation housing due to problems such as water leakage, which may affect the safety of the transformer due to water leakage in the substation housing.

[0012] Furthermore, the air-drying unit includes a driving motor II, a lifting frame and a conveying pipe. Rectangular grooves are symmetrically opened at both inner ends of the sealing door. A lead screw is rotatably connected in one rectangular groove, and a guide rod is fixedly connected in the other rectangular groove. A slider is threadedly connected to the lead screw, and a slider is slidably connected to the guide rod. The sliders are slidably connected to the inner walls of the rectangular grooves. The outer ends of the sliders are fixedly connected to the lifting frame. A blower is fixedly installed in the lifting frame. The blower is communicated with the conveying pipe. Both ends of the conveying pipe are fixedly connected to the inner wall of the lifting frame. Air outlet pipes are uniformly communicated with the conveying pipe. One ends of the air outlet pipes pass through the lifting frame and extend outwards. A driving motor II is fixedly installed at the upper end of the lifting frame. The output shaft of the driving motor II is fixedly connected to the lead screw.

[0013] Through the setting of the air-drying unit and the combined use of the fan and the air outlet pipe, the purpose of air-drying the sealing door can be achieved, and at the same time, it can effectively avoid economic losses caused by the damage of the sealing door due to dampness.

[0014] Furthermore, a waterproof layer is fixedly connected to the outer end of the sealing door, and a flame-retardant layer is fixedly connected to the outer end of the waterproof layer.

[0015] The flame-retardant layer can protect the sealing door from being damaged under high-temperature combustion, thereby ensuring the service life of the sealing door. The waterproof layer can prevent water from entering the sealing door and causing damage to it.

[0016] Furthermore, heat dissipation fans are evenly installed at the bottom end of the inner wall of the lower housing. Grooves are evenly formed at the upper end of the lower housing. Connecting blocks are connected in the grooves. The outer ends of the connecting blocks are fixedly connected to the ventilation plates. Through grooves are evenly formed on the ventilation plates. The input ends of the heat dissipation fans are electrically connected to the output end of an external controller.

[0017] Through the setting of the heat dissipation fans and the ventilation plates, it is convenient to efficiently dissipate heat and cool down the transformer inside the substation housing, avoiding the situation where the heat accumulated inside during the high-power operation of the transformer cannot be effectively discharged, which may affect the service life of the transformer.

[0018] Furthermore, air outlets are symmetrically formed at both ends of the lower housing, and dust-proof nets are fixedly connected inside the air outlets and the heat dissipation openings.

[0019] The setting of the dust-proof nets can prevent external dust from entering the inside of the substation housing and thus affecting the operation of the internal transformer.
