Description

Technical Field

[0001] This invention relates to the field of power distribution engineering technology, and in particular to a power distribution capacity expansion device for power distribution engineering. Background Technology

[0002] In today's society, the booming development of various industries has led to an explosive growth in electricity demand. In the industrial sector, modern factories widely use a large number of high-power equipment, such as large electric furnaces in steel plants and reaction devices in chemical enterprises. In the commercial sector, large shopping malls and office buildings that are constantly emerging in cities are equipped with dense lighting fixtures, central air conditioning systems, multiple elevators, and numerous office appliances. The improvement of residents' living standards has led to the rapid popularization of various household appliances, especially high-power appliances such as electric heaters, air conditioners, and electric water heaters, which have become standard equipment in households. Some families have also purchased electric vehicles, and the use of charging stations has further increased the electricity load.

[0003] However, in the industrial sector, modern factories widely use a large number of high-power equipment, such as large electric furnaces in steel plants and reaction devices in chemical enterprises. The power consumption during the production process is enormous, and the existing power distribution capacity is insufficient to support its full-load operation, which seriously restricts production efficiency and enterprise development. During the summer cooling and winter heating seasons, the demand for electricity rises sharply, and the existing power distribution system often faces overload pressure, which not only affects business operations but may also damage sensitive electronic equipment due to voltage instability. The power distribution facilities in old residential areas are mostly built according to the earlier, lower electricity standards, which cannot meet the current electricity demand of residents, and frequent power outages occur, causing many inconveniences to residents' lives. Furthermore, when staff maintain and upgrade the capacity, some capacity upgrade boxes are small and have limited operating space, making disassembly difficult and potentially leading to accidents. Therefore, a power distribution capacity upgrade device for power distribution engineering is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art where, when workers are maintaining capacity expansion devices, some expansion boxes are small, the operating space is limited, and disassembly is difficult, which may lead to accidents. Therefore, this invention proposes a power distribution capacity expansion device for power distribution engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power distribution capacity expansion device for power distribution engineering includes an expansion box. A torsion rod is rotatably connected to the bottom of the expansion box. A fixed gear is fixedly connected above the torsion rod. The fixed gear meshes with a fixed plate rack. A sliding plate is provided on the side of the fixed plate rack. A fixed plate is fixedly connected to the side of the sliding plate. A lifting threaded rod is rotatably connected above the fixed plate. A sliding groove block is threadedly connected to the lifting threaded rod. A shock-absorbing plate is provided on the side of the sliding groove block. A compression spring is provided below the shock-absorbing plate. A lifting plate is rotatably connected to the side of the shock-absorbing plate. A connecting gear is rotatably connected above the fixed plate. The connecting gear meshes with a connecting rack. The connecting rack is fixed to the side of the expansion box. The connecting gear is drivingly connected to the lifting threaded rod. A protective mechanism for removing dust from inside the expansion box is provided on the side of the sliding plate.

[0007] The above technical solution further includes:

[0008] The protection mechanism includes a first transmission belt disposed on the side of the fixed gear, the first transmission belt being driven to a cleaning threaded rod, the cleaning threaded rod being threaded to a movable brush, a dust cleaning plate being disposed above the fixed gear, and a cleaning strip frame for cleaning the surface of the dust cleaning plate being disposed on the side of the sliding plate.

[0009] The expansion chamber has heat dissipation holes on its side, and a movable brush is slidably connected to the side of the heat dissipation holes.

[0010] The expansion enclosure is equipped with a door on its side to protect the interior. A handle is located on one side of the door for closing the enclosure and protecting the internal equipment from external environmental influences. During normal operation, the door prevents dust, moisture, and foreign objects from entering the enclosure, ensuring the safe and stable operation of the internal equipment. When maintenance is required, opening the door facilitates operation by staff, improving maintainability and ease of use, while also enhancing the overall safety and protective performance of the device.

[0011] The sliding plate has holes on its surface, and multiple sets of fixing plates are provided on one side of the sliding plate to support the lifting plate, ensuring its stability during operation. Simultaneously, the installation and operation of components above the fixing plates, such as the lifting threaded rod and connecting gears, also rely on the fixing plates for fixation and support, ensuring the integrity and stability of the entire device's mechanical structure and contributing to reliable capacitor maintenance and other functions.

[0012] The bottom of the expansion box is provided with a sliding groove for fixing the rack and pinion, and the surface of the dust cleaning plate is provided with a groove for sliding the sliding plate. The box is slidably connected above the sliding plate.

[0013] The connecting gear is connected to a second transmission belt, which is connected to a lifting threaded rod. A stabilizing column is provided on one side of the lifting threaded rod, and the stabilizing column is slidably connected to the sliding groove block.

[0014] The side of the expansion box is provided with a slot for fixing the connecting rack, and the slot on the side of the expansion box is provided with a connecting rack sufficient to move the sliding plate to the outside of the expansion box.

[0015] The capacity expansion housing is rotatably connected to a cleaning threaded rod, which is rotatably connected to a dust removal plate and threadedly connected to a movable brush. During rotation, the movable brush moves along the heat dissipation holes, cleaning them. Through precise threaded transmission, the cleaning threaded rod can control the speed and position of the movable brush, ensuring comprehensive and efficient cleaning of the heat dissipation holes, guaranteeing unobstructed flow, improving the heat dissipation efficiency of the capacity expansion housing, and preventing overheating due to dust clogging the holes, thus ensuring the safe and stable operation of the equipment.

[0016] The side of the movable brush is provided with a cleaning layer for cleaning the heat dissipation holes.

[0017] The present invention has the following beneficial effects:

[0018] 1. In this invention, the unique sliding plate design achieves sliding through the cooperation of a torsion rod, a fixed plate rack, and a fixed box gear, creating a larger operating space for workers. Compared to the traditional cramped operating environment of expansion boxes, this expandable space allows workers to inspect and maintain equipment more freely, without having to operate in a confined space, greatly improving maintenance efficiency and ease of operation, and reducing problems such as inconvenient tool use and difficulty in accessing parts caused by limited operating space.

[0019] 2. In this invention, the lifting function of the lifting plate effectively solves the problem of difficulty for workers to access the capacitor plate and the risk of accidents. During maintenance, the lifting plate is raised through a series of transmission mechanisms, including gears, racks, a second transmission belt, and a lifting threaded rod, placing the capacitor in a more convenient position for operation. This reduces the safety risks of electric shock and collisions that may occur due to workers operating in uncomfortable postures such as bending over or turning sideways, providing safer conditions for maintenance work.

[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 Figures 1-6 As shown, the present invention is a power distribution capacity expansion device for power distribution engineering, including a capacity expansion box 1. A torsion rod 14 is rotatably connected to the bottom of the capacity expansion box 1. A fixed box gear 13 is fixedly connected above the torsion rod 14. The fixed box gear 13 is meshed with a fixed plate rack 12. A sliding plate 2 is provided on the side of the fixed plate rack 12. A fixed plate 3 is fixedly connected to the side of the sliding plate 2. A lifting threaded rod 9 is rotatably connected above the fixed plate 3. A sliding groove block 6 is threadedly connected to the lifting threaded rod 9. A shock-absorbing plate 5 is provided on the side of the sliding groove block 6. A compression spring 8 is provided below the shock-absorbing plate 5. A lifting plate 4 is rotatably connected to the side of the shock-absorbing plate 5. A connecting gear 20 is rotatably connected above the fixed plate 3. A connecting gear 20 is meshed with a connecting rack 21. The connecting rack 21 is fixed to the side of the capacity expansion box 1. The connecting gear 20 is drivenly connected to the lifting threaded rod 9. A protective mechanism for removing dust from the inside of the capacity expansion box 1 is provided on the side of the sliding plate 2.

[0029] In one embodiment, the protection mechanism includes a first transmission belt 15 disposed on the side of the fixed gear 13, a cleaning threaded rod 17 being drivenly connected to the first transmission belt 15, a movable brush 18 being threadedly connected to the cleaning threaded rod 17, a dust cleaning plate 10 being disposed above the fixed gear 13, and a cleaning strip frame 11 for cleaning the surface of the dust cleaning plate 10 being disposed on the side of the sliding plate 2.

[0030] In this embodiment, a protective mechanism is installed inside the capacity expansion box 1 to ensure that the overall internal temperature drops, thereby preventing the internal capacitors from being damaged by excessively high temperatures.

[0031] In one embodiment, for the storage box 1, a heat dissipation hole 19 is provided on the side of the expansion box 1, and a movable brush 18 is slidably connected to the side of the heat dissipation hole 19.

[0032] In one embodiment, for the aforementioned capacity expansion box 1, a capacity expansion box door 22 for protecting the interior is provided on the side of the capacity expansion box 1, and a handle is provided on one side of the capacity expansion box door 22.

[0033] In this embodiment, the outer shell of the entire power distribution capacity expansion device provides physical protection for the internal electrical components, preventing dust, moisture, foreign objects, etc. from entering, protecting the internal equipment from interference and damage from the external environment, ensuring that the power distribution capacity expansion device can operate in a relatively stable environment, and improving the reliability and service life of the equipment.

[0034] In one embodiment, the sliding plate 2 has holes on its surface, and a plurality of fixing plates 3 for supporting the lifting plate 4 are provided on one side of the sliding plate 2.

[0035] In this embodiment, its movement facilitates the maintenance and cleaning of internal equipment. When the sliding plate 2 moves outward, on the one hand, it allows staff to more easily access and operate the components fixed on it, such as the capacitors on the lifting plate 4; on the other hand, the related components on its side (such as the connecting gear 20, the cleaning strip 11, etc.) can interact with the corresponding components inside the capacity expansion box 1 to achieve functions such as cleaning the heat dissipation holes 19 and raising and lowering the lifting plate 4, thereby improving the efficiency and convenience of equipment maintenance.

[0036] In one embodiment, for the aforementioned capacity expansion box 1, a sliding groove for the fixed plate rack 12 is provided at the bottom of the capacity expansion box 1, a groove for the sliding plate 2 is provided on the surface of the dust cleaning plate 10, and a box sliding groove 16 is slidably connected above the sliding plate 2.

[0037] In this embodiment, multiple grooves are provided to ensure stability when the sliding plate 2 moves.

[0038] In one embodiment, the connecting gear 20 is connected to a second transmission belt 23, which is connected to a lifting threaded rod 9. A stabilizing post 7 is provided on one side of the lifting threaded rod 9. The stabilizing post 7 is slidably connected to the sliding groove block 6. The capacity-enhancing box 1 is rotatably connected to the cleaning threaded rod 17. The cleaning threaded rod 17 is rotatably connected to the dust cleaning plate 10. A cleaning layer for cleaning the heat dissipation holes 19 is provided on the side of the moving brush 18.

[0039] In this embodiment, on the one hand, it meshes with the connecting rack 21 to achieve mechanical connection and transmission with the expansion housing 1; on the other hand, it is connected to the lifting threaded rod 9 through a transmission belt, transmitting its own rotation to the lifting threaded rod 9, thereby realizing the lifting control of the lifting plate 4. This multi-transmission connection method enables the various components of the device to cooperate closely and work together, improving the automation level and ease of operation of the device, while also ensuring the stability and reliability of the device during operation.

[0040] The working principle of a power distribution capacity expansion device for power distribution engineering in this invention is as follows: First, the staff opens the capacity expansion box door 22 and then observes whether there are any damaged parts inside. If not, maintenance is carried out.

[0041] Then, the operator twists the torsion bar 14, causing the sliding plate 2 to engage with the fixed gear 13 via the fixed plate rack 12 at its bottom. As the sliding plate 2 slides, it cleans the dust accumulated on the surface of the dust removal plate 10 via the fixed cleaning strip frame 11, according to the number of turns of the torsion bar 14. The rotation of the fixed gear 13 then drives the cleaning threaded rod 17 via the first transmission belt 15. The rotation of the cleaning threaded rod 17 causes the moving brush 18 to move across the surface of the heat dissipation holes 19, thereby removing the accumulated dust and ensuring the cleanliness of the interior of the expansion housing 1. For heat dissipation, when the sliding plate 2 moves, a connecting gear 20 is provided above the fixed plate 3 fixed on the side. The sliding plate 2 slides the connecting gear 20, which will mesh with the connecting rack 21 fixed inside the expansion box 1. Then the connecting gear 20 will rotate. The rotation of the connecting gear 20 will drive the lifting threaded rod 9 to rotate through the second transmission belt 23. The lifting threaded rod 9 rotates and the sliding groove block 6 will slide and rise along the stabilizing column 7. Then the shock-absorbing plate 5 fixed on the side of the sliding groove block 6 will move upward relative to the fixed plate 3. One end of the lifting plate 4 fixed on the side of the shock-absorbing plate 5 will be lifted.

[0042] Then, the staff can properly repair the capacitors exposed on the surface of the lifting plate 4, preventing accidents caused by contact with the capacitor plate. When the lifting plate 4 is laid flat, the compression spring 8 under the sliding groove block 6 of the shock-absorbing plate 5 can provide cushioning, thereby preventing the connector from becoming loose due to vibration.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
