Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution station technology, specifically a prefabricated box-type power distribution station. Background Technology
[0002] Currently, prefabricated box-type substations are compact, factory-prefabricated indoor / outdoor power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. This organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. They are particularly suitable for urban power grid construction and renovation, representing a new type of substation that has emerged after traditional civil engineering substations. Box-type substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering distribution rooms and substations as a new type of complete power distribution system. While substations typically use screens to prevent insects and small animals, prolonged use of these screens can lead to the accumulation of large dust particles that clog the mesh, reducing ventilation and heat dissipation efficiency.
[0003] Chinese utility model CN219659271U describes a safety-type box-type substation design that includes a substation screen cleaning structure. The principle is that a motor drives a rotating shaft to rotate, which in turn causes a roller to rotate and a sliding belt to rotate, thus causing the waterproof shell to reciprocate on the substation. Inside the waterproof shell, a cleaning wiper is installed to wipe the screen on the substation.
[0004] However, existing devices rely on a cleaning wipe to clean window screens, which struggles to remove hair and lint, resulting in poor cleaning performance. Therefore, a rotating brush handle structure was designed to address this issue, leading to significantly improved cleaning results. Utility Model Content

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a prefabricated box-type substation, which has the following advantages:
[0018] 1. This distribution cabinet uses a motor to drive the threaded rod to rotate through the cleaning component, which in turn drives the U-shaped plate to rise. As the U-shaped plate rises, the gears and racks on the brush rod mesh, causing the brush rod to rotate. This increases the friction between the brush rod and the screen, resulting in a better cleaning effect.
[0019] 2. This distribution cabinet uses a mounting component to restrict the bottom of the through slot by using a rod, which can restrict the brush rod. At the same time, the pull rod controls the rod to retract into the housing, which can release the restriction on the brush rod, thereby allowing the brush rod to be replaced.

For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0030] Currently, prefabricated box-type substations are compact, factory-prefabricated indoor / outdoor power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. This organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. They are particularly suitable for urban power grid construction and renovation, representing a new type of substation that has emerged after traditional civil engineering substations. Box-type substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering distribution rooms and substations as a new type of complete power distribution system. While substations typically use screens to prevent insects and small animals, prolonged use of these screens can lead to the accumulation of large dust particles that clog the mesh, reducing ventilation and heat dissipation efficiency.
[0031] In related technologies, a motor drives a rotating shaft, which in turn rotates a roller that drives a sliding belt, causing a waterproof casing to reciprocate on the substation. Inside the casing, a cleaning wiper is installed to clean the screens on the distribution cabinet. However, existing devices rely on this cleaning wiper to clean the screens, and it's difficult to remove hair or lint effectively. Therefore, the cleaning method used in existing devices is ineffective.
[0032] To address some of the problems in related technologies, this application provides a prefabricated box-type substation. When cleaning the screen 12 on the main body 11 of the distribution cabinet is required, the motor 21 is first connected to an external power source to drive the threaded rod 22 to rotate. As the threaded rod 22 rotates, it contacts the U-shaped plate 23. At this time, one side of the U-shaped plate 23 is in contact with the main body 11 of the distribution cabinet, restricting the U-shaped plate 23 from rotating. Therefore, as the threaded rod 22 rotates, it drives the U-shaped plate 23 to move upward. During the movement, the gear 25 on the brush rod 24 on the inner wall of the U-shaped plate 23 meshes with the rack 26 on the main body 11 of the distribution cabinet, driving the gear 25 to rotate and simultaneously driving the brush rod 24 to rotate as well. As the brush rod 24 rotates, the brush on the surface contacts the screen 12 to clean the impurities on the surface of the screen 12. When it is necessary to replace the brush rod 24, simply pull the lever 35 to move the rod 34 back into the housing 32 to release the restriction on the brush rod 24. After the brush rod 24 is pulled out from the through groove 31 and a new brush rod 24 is replaced, release the lever 35. The spring 33 will rebound and push the rod 34 to move out from the housing 32, restricting the position of the brush rod 24 so that it will not fall out from the through groove 31.
[0033] This application is described below with reference to the accompanying drawings and specific embodiments:
[0034] Combination Figures 1-4 This application provides a prefabricated box-type substation, including: a distribution cabinet body 11, with a screen window 12 on its outer side wall; a cleaning assembly 2 is provided on the distribution cabinet body 11, the cleaning assembly 2 including: a motor 21, disposed on the outer side wall of the distribution cabinet body 11; a threaded rod 22, disposed on the output shaft at the bottom of the motor 21; a U-shaped plate 23, penetrated by the threaded rod 22 and threadedly connected to the threaded rod 22; a brush rod 24, disposed on the inner side of the U-shaped plate 23; a gear 25, fixedly sleeved on the outer side wall of the brush rod 24; and a rack 26, disposed on the outer side wall of the distribution cabinet body 11 and meshing with the gear 25.
[0035] Specifically, the main body of the distribution cabinet, model 11, is designated GGD. Its operation process is as follows: Power input: The distribution cabinet receives power from the power supply network. The power input is usually controlled by the main switch and can be operated manually or automatically.
[0036] Power Distribution: Once power is input to the distribution cabinet, it is distributed to different load devices. Circuit breakers will manually or automatically control the circuit according to load demand to ensure that each load device receives an appropriate power supply.
[0037] Power protection: During power distribution, the distribution cabinet uses protective devices to protect the power supply system and load equipment. These devices detect faults and abnormalities in the circuits and disconnect faulty circuits to ensure the safe operation of the power supply system.
[0038] Power control: The distribution cabinet can be manually or automatically controlled via control equipment. Operators can use devices such as switches, buttons, and indicator lights to monitor and control the operating status of the distribution cabinet.
[0039] Enhanced system reliability: To enhance the reliability of the power supply system, distribution cabinets typically employ backup power supplies and automatic switching devices. When the main power supply fails, the backup power supply automatically switches to ensure uninterrupted power supply.
[0040] When cleaning the screen 12 on the main body 11 of the power distribution cabinet, first connect the motor 21 to the external power supply to drive the threaded rod 22 to rotate. As the threaded rod 22 rotates, it will contact the U-shaped plate 23. At this time, one side of the U-shaped plate 23 is attached to the main body 11 of the power distribution cabinet, restricting the U-shaped plate 23 from rotating. So, as the threaded rod 22 rotates, it will drive the U-shaped plate 23 to move upward. During the movement, the gear 25 on the brush rod 24 on the inner wall of the U-shaped plate 23 will mesh with the rack 26 on the main body 11 of the power distribution cabinet, driving the gear 25 to rotate and simultaneously driving the brush rod 24 to rotate. As the brush rod 24 rotates, the brush on the surface will contact the screen 12 to clean the impurities on the surface of the screen 12.
[0041] In some embodiments, the cleaning component 2 further includes a baffle 27 disposed at the bottom of the threaded rod 22.
[0042] When in use, the baffle 27 can prevent the U-shaped plate 23 from disengaging from the threaded rod 22 during movement.
[0043] In some embodiments, the cleaning assembly 2 further includes: multiple lifting rods 28, all disposed on the inner sidewall of the U-shaped plate 23, with their bottom ends inserted into the brush of the brush rod 24.
[0044] When in use, as the brush handle 24 rotates and comes into contact with the screen 12, it will wrap the hair and lint on the surface of the screen 12. At the same time, as it rotates, one end of the pick rod 28 extends into the brush and can pick out the wrapped lint, thereby achieving the effect of cleaning the brush handle 24.
[0045] In some embodiments, the cleaning component 2 further includes a plurality of ball bearings 29, all disposed on one side of the U-shaped plate 23.
[0046] When in use, the ball bearing 29 reduces friction when the U-shaped plate 23 contacts the power distribution cabinet body 11 during movement, making the sliding smoother.
[0047] In some embodiments, mounting components 3 are symmetrically arranged on the U-shaped plate 23. The mounting components 3 include: a through groove 31 formed on the outer side wall of the U-shaped plate 23 and penetrated by one end of the brush rod 24; a housing 32 fixedly disposed on the outer side wall of the U-shaped plate 23; a spring 33 disposed inside the housing 32; one end of a rod 34 inserted into the inside of the housing 32 and connected to the spring 33; and one end of a pull rod 35 penetrating the outer side wall of the housing 32 and passing through the spring 33 and connected to the rod 34.
[0048] When it is necessary to replace the brush rod 24, simply pull the lever 35 to move the rod 34 back into the housing 32, thereby releasing the restriction on the brush rod 24. After the brush rod 24 is pulled out from the through groove 31 and a new brush rod 24 is replaced, release the lever 35. The spring 33 will rebound and push the rod 34 to move out from the housing 32, restricting the position of the brush rod 24 so that it will not fall out from the through groove 31.
[0049] In some embodiments, the outer side wall of the rod 34 is provided with an arc-shaped groove that fits against the outer side wall of one end of the brush rod 24.
[0050] When in use, the arc-shaped design at the top of the rod 34, which fits against the outer wall of the brush rod 24, can reduce the scraping of the brush rod 24 when it rotates.
[0051] In some embodiments, the cleaning component 2 further includes a pull rod 36 disposed at one end of the pull rod 35.
[0052] When in use, the pull knob 36 is designed for easy gripping and controls the movement of the pull rod 35, thereby pulling the rod 34 back into the interior of the housing 32.
[0053] In some embodiments, the mounting assembly 3 further includes a ring 37 fixedly sleeved on the outer side wall of the brush rod 24.
[0054] When in use, the ring 37 can limit the position of the brush rod 24 and prevent the brush rod 24 from shaking inside the U-shaped plate 23.
