Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, specifically a prefabricated substation. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor / outdoor power distribution unit that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It 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. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after traditional civil engineering substations. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering substations and becoming a new type of complete power distribution system.

[0003] When a prefabricated substation is installed and used, it relies on a louvered structure on the enclosure for ventilation and heat dissipation. Since the working location of a prefabricated substation is often outdoors, during the heat dissipation and protection process using the louvered structure, external dust will continuously accumulate on the louvered slats, reducing the gap between adjacent slats and further reducing the heat dissipation effect of the louvered structure on the prefabricated substation. In addition, during the heat dissipation process, external flying insects and small animals can pass through the gaps in the slats and enter the interior of the prefabricated substation, causing abnormalities in the internal wiring.

[0004] Therefore, there is an urgent need for a prefabricated substation to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated substation to solve the problems of poor heat dissipation and low protection effect of the louver structure in prefabricated substations mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated substation, comprising a substation enclosure, with multiple lifting rings threaded to the upper end of the enclosure, and further comprising an installation groove formed on the enclosure and a fixing frame disposed outside the enclosure. The installation groove is provided with a protective component for protection during heat dissipation inside the enclosure. The protective component includes the installation frame. Multiple connecting components for connecting the installation frame are disposed on the inner side of the enclosure. Multiple protective members are vertically arranged and fixed inside the installation frame. Each protective member consists of a first baffle and a second baffle, which are arranged in a V-shape. The fixing frame is located outside the installation groove. The fixing frame is provided with a cleaning component for cleaning each of the first and second baffles and a striking component for protection against impacts to the installation frame during cleaning.

[0007] The cleaning assembly includes a strip plate mounted on a fixed frame. A mounting plate is connected to the strip plate via a pushing assembly. A cleaning brush is mounted on the mounting plate on the side facing the mounting frame. The fixed frame is equipped with a lifting assembly for raising and lowering the strip plate and a guide assembly for guiding the raising and lowering process.

[0008] The pushing assembly includes a plurality of first T-shaped rods slidably connected to the strip plate. One end of each first T-shaped rod is fixed to the mounting plate. A first spring is sleeved on the side wall of each first T-shaped rod. The two ends of the first spring are respectively connected to one end of the first T-shaped rod and the strip plate. The cleaning brush on the mounting plate is abutted against the mounting frame under the elastic force of each first spring.

[0009] The lifting assembly includes a first connecting plate fixed to one side of the strip plate, a threaded sleeve fixed on the first connecting plate, a threaded rod rotatably connected to the fixed frame, the threaded sleeve and the threaded rod being meshed with each other, and a drive motor for driving the threaded rod being installed on the fixed frame.

[0010] The guide assembly includes a second connecting plate fixed to the other side of the strip plate, and a guide rod is slidably connected to the second connecting plate. The guide rod is fixed inside the fixed frame.

[0011] The connecting assembly includes an L-shaped frame fixed inside the substation box, a second T-shaped rod slidably connected to the L-shaped frame, one end of the second T-shaped rod being fixed to the mounting frame, and a second spring being sleeved on the side wall of the second T-shaped rod, with both ends of the second spring being connected to the L-shaped frame and the mounting frame respectively.

[0012] The striking assembly includes a rectangular plate fixed to one side of the first connecting plate, a rotating shaft rotatably connected to the rectangular plate, a turntable fixed to one end of the rotating shaft, and a plurality of rubber protrusions arranged in a circular array on the turntable for striking and pushing the mounting frame. A drive assembly for driving the rotating shaft is provided on the outside of the substation enclosure.

[0013] The drive assembly includes a rack fixed to the outside of the substation enclosure, and a gear is fixed to one end of the rotating shaft. The gear and the rack are meshed with each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In the case of a box-type substation of the present invention, during the heat dissipation process, the gap between two adjacent protective components gradually decreases from the outside to the inside of the mounting frame through the first baffle and the second baffle arranged in a V shape. This facilitates the entry of external air into the interior of the substation box for ventilation and heat dissipation, while the gradually decreasing space effectively blocks external flying insects and small animals, reducing the probability of external flying insects and small animals entering the interior of the substation box.

[0016] 2. In a box-type substation of the present invention, during the lifting and lowering movement of the strip plate, the pushing action of the pushing component causes the cleaning brush on the mounting plate to abut against and slide against the surfaces of the first baffle and the second baffle, thereby cleaning the dust accumulated on the surfaces of the first baffle and the second baffle, maintaining the gap between adjacent protective components, and further ensuring the ventilation and heat dissipation effect between the substation box and the outside.

[0017] 3. In the box-type substation of the present invention, during the lifting and lowering of the strip plate, the sound produced by the knocking between each rubber protrusion and the mounting frame can scare away flying insects and small animals approaching the substation box, thereby further improving the effectiveness of the substation box in preventing flying insects and small animals from entering.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-8 This invention provides a prefabricated substation, including a substation enclosure 1. Multiple lifting rings 2 are threadedly connected to the upper end of the enclosure 1. The substation enclosure 1 also includes a mounting groove 301 formed on the enclosure 1 and a fixing frame 5 disposed outside the enclosure 1. The mounting groove 301 is provided with protective components for protecting the substation enclosure 1 during internal heat dissipation. The protective components include the mounting frame 302. Multiple connecting components for connecting to the mounting frame 302 are disposed on the inner side of the substation enclosure 1. Multiple protective members are vertically arranged and fixed inside the mounting frame 302. Each protective member consists of a first baffle 303 and a second baffle 304, which are arranged in a V-shape. The fixing frame 5 is located on the outside of the mounting groove 301. The fixing frame 5 is equipped with a cleaning component for cleaning each of the first baffles 303 and the second baffles 304, and a knocking component for protection against knocking on the mounting frame 302 during the cleaning process. During the heat dissipation process, the gap between two adjacent protective components gradually decreases from the outside of the mounting frame 302 to the inside of the mounting frame 302 through the V-shaped first baffles 303 and the second baffles 304. This facilitates the entry of external air into the interior of the substation enclosure 1 for ventilation and heat dissipation. At the same time, the gradually decreasing space effectively blocks external flying insects and small animals, reducing the probability of external flying insects and small animals entering the interior of the substation enclosure 1.

[0029] The cleaning assembly includes a strip plate 601 mounted on a fixed frame 5. A mounting plate 602 is connected to the strip plate 601 via a pushing assembly. A cleaning brush 603 is mounted on the side of the mounting plate 602 facing the mounting frame 302. The fixed frame 5 is equipped with a lifting assembly for raising and lowering the strip plate 601 and a guide assembly for guiding the movement during the raising and lowering process. Through the lifting assembly, the strip plate 601 is subjected to force and moves up and down on the fixed frame 5. During the raising and lowering movement of the strip plate 601, the cleaning brush 603 on the mounting plate 602 is pushed by the first spring 702 on each of the first T-shaped rods 701, causing it to abut against and slide against the surfaces of the first baffle 303 and the second baffle 304, cleaning the dust accumulated on the surfaces of the first baffle 303 and the second baffle 304, maintaining the gap between adjacent protective components, and further ensuring the ventilation and heat dissipation effect between the substation enclosure 1 and the outside.

[0030] The pushing component includes a plurality of first T-shaped rods 701 slidably connected to the strip plate 601. One end of each first T-shaped rod 701 is fixed to the mounting plate 602. A first spring 702 is sleeved on the side wall of each first T-shaped rod 701. The two ends of the first spring 702 are respectively connected to one end of the first T-shaped rod 701 and the strip plate 601. The cleaning brush 603 on the mounting plate 602 is abutted against the mounting frame 302 under the elastic force of each first spring 702. Through the pushing action of the first spring 702 on each first T-shaped rod 701, the cleaning brush 603 on the mounting plate 602 is kept in contact with the surfaces of the first baffle 303 and the second baffle 304, thereby improving the cleaning effect.

[0031] The lifting assembly includes a first connecting plate 801 fixed to one side of the strip plate 601, a threaded sleeve 802 fixed on the first connecting plate 801, a threaded rod 803 rotatably connected to the fixed frame 5, the threaded sleeve 802 and the threaded rod 803 being meshed with each other, and a drive motor 804 for driving the threaded rod 803 being installed on the fixed frame 5. The guiding assembly includes a second connecting plate 901 fixed to the other side of the strip plate 601, a guide rod 902 slidably connected to the second connecting plate 901, and the guide rod 902 being fixed inside the fixed frame 5. The drive motor 804 drives the threaded rod 803 to rotate. During the rotation of the threaded rod 803, the meshing transmission between the threaded rod 803 and the threaded sleeve 802 and the guiding effect of the guide rod 902 and the second connecting plate 901 on the strip plate 601 cause the strip plate 601 to be subjected to force and move up and down on the fixed frame 5.

[0032] The connecting assembly includes an L-shaped frame 401 fixed inside the substation enclosure 1. A second T-shaped rod 402 is slidably connected to the L-shaped frame 401. One end of the second T-shaped rod 402 is fixed to the mounting frame 302. A second spring 403 is sleeved on the side wall of the second T-shaped rod 402. Both ends of the second spring 403 are connected to the L-shaped frame 401 and the mounting frame 302, respectively. Through the action of each second T-shaped rod 402 and the L-shaped frame 401, the mounting frame 302 under stress is guided. Through the elastic force of each second spring 403, the mounting frame 302 under stress is easily pushed to reset.

[0033] The striking assembly includes a rectangular plate 1001 fixed to one side of the first connecting plate 801. A rotating shaft 1002 is rotatably connected to the rectangular plate 1001. A turntable 1003 is fixed to one end of the rotating shaft 1002. Multiple rubber protrusions 1004 for striking and pushing the mounting frame 302 are arranged in a circular array on the turntable 1003. A drive assembly for driving the rotating shaft 1002 is provided on the outside of the substation enclosure 1. The drive assembly drives the rotating shaft 1002 and the turntable 1003 at one end of the rotating shaft 1002 to rotate. During the rotation of the turntable 1003, the mounting frame 302 is intermittently struck by the various rubber protrusions 1004. The pushing and squeezing action of the second T-shaped rod 402 and the pushing and resetting action of the second spring 403 on each of the second T-shaped rods 402 on the squeezed mounting frame 302 cause the mounting frame 302 to reciprocate on the mounting groove 301 as the rotating shaft 1002 rotates. Through the reciprocating motion of the mounting frame 302, it is easier to clean the dust accumulated on the surface of the first baffle 303 and the second baffle 304. In addition, the sound produced by the knocking between each rubber protrusion 1004 and the mounting frame 302 can scare away flying insects and small animals that approach the substation box 1, further improving the effect of preventing flying insects and small animals from entering the substation box 1.

[0034] The drive assembly includes a rack 1101 fixed to the outside of the substation housing 1, and a gear 1102 fixed to one end of the rotating shaft 1002. The gear 1102 and the rack 1101 are meshed with each other. During the process of driving the strip plate 601 to move up and down on the fixed frame 5, the rectangular plate 1001 on the first connecting plate 801 is driven to move up and down synchronously. During the process of the rectangular plate 1001 moving up and down, the rotating shaft 1002 and the turntable 1003 at one end of the rotating shaft 1002 are driven to rotate through the meshing transmission between the gear 1102 and the rack 1101.

[0035] Working principle: When the prefabricated substation is used outdoors, the heat generated inside the prefabricated substation can be discharged to the outside through the gaps between the various protective components on the mounting frame 302, thus dissipating heat inside the prefabricated substation. During the heat dissipation process, the gap between two adjacent protective components is gradually reduced from the outside to the inside of the mounting frame 302 by the first baffle 303 and the second baffle 304, which are arranged in a V-shape. This facilitates the entry of external air into the substation enclosure 1 for ventilation and heat dissipation. At the same time, the gradually decreasing space also blocks external flying insects and small animals, reducing the probability of them entering the substation enclosure 1.

[0036] During the protective process, the dust accumulated on the first baffle 303 and the second baffle 304 needs to be cleaned regularly. During the cleaning process, the drive motor 804 drives the threaded rod 803 to rotate. During the rotation of the threaded rod 803, the mutual meshing transmission between the threaded rod 803 and the threaded sleeve 802 and the guiding action of the guide rod 902 and the second connecting plate 901 on the strip plate 601 cause the strip plate 601 to be subjected to force and move up and down on the fixed frame 5. During the up and down movement of the strip plate 601, the pushing action of the first spring 702 on each first T-shaped rod 701 causes the cleaning brush 603 on the mounting plate 602 to abut against and slide against the surfaces of the first baffle 303 and the second baffle 304, cleaning the dust accumulated on the surfaces of the first baffle 303 and the second baffle 304, maintaining the gap between adjacent protective components, and further ensuring the ventilation and heat dissipation effect between the substation enclosure 1 and the outside.

[0037] During the lifting and lowering motion of the drive strip plate 601 on the fixed frame 5, the rectangular plate 1001 on the first connecting plate 801 is driven to lift and lower synchronously. During the lifting and lowering motion of the rectangular plate 1001, the meshing transmission between the gear 1102 and the rack 1101 drives the rotating shaft 1002 and the turntable 1003 at one end of the rotating shaft 1002 to rotate. During the rotation of the turntable 1003, the intermittent pushing and squeezing action of the mounting frames 302 on each rubber protrusion 1004 and the second T-shaped rods 402 cause the rectangular plate 1001 on the first connecting plate 801 to lift and lower synchronously. The spring 403 pushes and resets the compressed mounting frame 302, causing the mounting frame 302 to reciprocate on the mounting groove 301 as the rotating shaft 1002 rotates. The reciprocating motion of the mounting frame 302 makes it easier to clean the dust accumulated on the surfaces of the first baffle 303 and the second baffle 304. Furthermore, the sound produced by the knocking between the various rubber protrusions 1004 and the mounting frame 302 can scare away flying insects and small animals that approach the substation enclosure 1, further improving the effectiveness of the substation enclosure 1 in preventing flying insects and small animals from entering.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
