Description

Technical Field

[0001] The utility model relates to a dustproof structure of a prefabricated cabin type transmission and transformation station. Background Art

[0002] The prefabricated cabin-type substation consists of a prefabricated cabin shell, equipment cabinets (or racks), cabin auxiliary facilities, etc. The production, assembly, wiring, and debugging are completed in the factory, and the cabin is transported to the project site in the form of a container room for installation. The prefabricated cabin shell adopts a steel structure container room. The cabin shell is equipped with auxiliary facilities such as fire protection, security, HVAC, lighting, communication, intelligent auxiliary control system, centralized distribution frame (cabin) according to needs. The environment should meet the operating conditions of the substation equipment and the on-site operation requirements of the substation operation and debugging personnel. The prefabricated cabin and the equipment inside it are integrated by the manufacturer as a whole, and factory processing is realized, which reduces on-site secondary wiring, reduces the design, construction, debugging, and workload, simplifies inspection and maintenance work, shortens the construction period, and effectively supports the rapid construction of the power grid. It has the technical characteristics of standardization, modularization, and prefabrication. However, the following problems still exist in the actual operating environment:

[0003] 1. Impact of dust: Dust particles in the air can easily enter the interior of the pre-shell and accumulate on the surface of the power transmission and transformation equipment. Long-term accumulation of dust may affect the heat dissipation performance of the equipment, causing the equipment temperature to rise, affecting the normal operation and service life of the equipment; dust may also cause the electrical insulation performance to deteriorate, increasing the risk of equipment failures such as short circuits and leakage.

[0004] 2. Insufficient traditional protection: The sealing measures of traditional prefabricated housings may have certain limitations and cannot completely prevent the ingress of dust. Some simple protection measures, such as the use of dustproof cotton, are ineffective and not durable.

[0005] 3. Environmental factors: Prefabricated cabins may be installed in various environments, such as industrial areas and outdoors. The dust content in these places is relatively high, posing a greater threat to the safe operation of power transmission and transformation equipment.

[0006] Existing dust screens are riveted to the dust-proof openings on the hull and cannot be removed. Due to the high degree of integration and limited space in prefabricated pod-type transmission and substations, replacing dust screens takes a long time, resulting in significant power loss and increased difficulty. They can also easily damage equipment by accidentally touching cables or components.

[0007] As the power system's requirements for equipment reliability continue to increase, a more effective dust prevention measure is needed to ensure the safe and stable operation of prefabricated cabin-type transmission and substations. Utility Model Content

[0009] The purpose of the utility model is achieved as follows: a dustproof structure of a prefabricated cabin type transmission and substation, comprising a prefabricated cabin shell of a box structure and a dustproof component; a rectangular dustproof opening is opened on one side wall of the cabin shell; wherein,

[0010] The dustproof assembly includes a rain cover, an insert-type air filter bag and a partition inner cover;

[0011] The outline shape of the rain cover is adapted to the shape of the dustproof port and includes a frame and a shutter embedded on the outside of the frame, one side of the frame of the rain cover is connected to the dustproof port via a plurality of hinges, and the other side of the frame of the rain cover is fixed to the dustproof port via a plurality of duckbill locks;

[0012] The insert-type air filter bag is embedded in the middle of the frame of the rain cover;

[0013] The barrier inner cover is embedded in the inner side of the frame of the rainproof cover, and the barrier inner cover comprises an inner cover frame and an inner cover net integrally connected in the inner cover frame.

[0014] In the dustproof structure of the above-mentioned prefabricated cabin-type transmission and substation, the inner shield of the partition is transformed from the blades of retired wind turbines.

[0015] The dustproof structure of the prefabricated cabin type transmission and substation of the utility model is characterized by:

[0016] 1. Highly efficient dust prevention: The fine mesh structure of the strip-type air filter bag can effectively block dust particles, prevent them from entering the power transmission and transformation equipment, and reduce the risk of equipment failure.

[0017] 2. Good air permeability: The strip-type air filter bag blocks dust while ensuring air circulation, avoiding affecting the heat dissipation performance of the equipment.

[0018] 3. Corrosion resistance and wear resistance: Select corrosion-resistant and wear-resistant materials to adapt to various harsh environments and are not easily damaged after long-term use.

[0019] 4. Safe operation: The dust in the space environment is reduced, which facilitates the sanitation and cleaning work in the cabin, reduces the safety hazards of equipment, and improves the power generation efficiency.

[0020] 5. Easy installation: reasonable design, easy and quick installation, can be customized and installed according to the size of the prefabricated cabin.

[0021] 6. Low maintenance cost: No special maintenance is required, regular cleaning can maintain good dust-proof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] See also Figures 1 to 4 The dustproof structure of the prefabricated cabin type transmission and substation of the present invention includes a hexahedral prefabricated cabin shell 1 and a dustproof component.

[0028] The cabin shell 1 is a box structure and includes a front panel, a back panel, two side panels, a bottom panel and a top panel; a rectangular dustproof port is opened on one side of the front panel;

[0029] The dustproof component includes a rain cover 2, an insert-type air filter bag 3 and a partition inner cover 4;

[0030] The outline shape of the rain cover 2 is adapted to the shape of the dustproof opening on the cabin shell 1. The rain cover 2 includes a frame 21 and a shutter 22 embedded on the outside of the frame 21. One side of the frame 21 of the rain cover 2 is connected to the dustproof opening via two high-strength hinges 5, and the other side of the frame 21 of the rain cover 2 is fixed to the dustproof opening via three duckbill locks 6.

[0031] The strip-type air filter bag 3 is embedded in the middle of the frame 21 of the rain cover 2;

[0032] The barrier inner cover 4 is embedded in the inner side of the frame 21 of the rainproof cover 2, and the barrier inner cover 4 comprises an inner cover frame 41 and an inner cover net 42 integrally connected to the inner cover frame 41. The barrier inner cover 4 is transformed from the blades of retired wind turbines.

[0033] The shutters 22 of the rain cover 2 in the present invention can prevent rainwater from directly entering the interior of the cabin shell 1, reducing safety issues such as short circuits and failures of electrical equipment in the cabin shell 1 caused by moisture. By preventing rainwater from intruding, the equipment in the cabin shell 1 is protected from water damage, and the service life of the equipment is extended. The rain cover 2 is opened and closed by high-strength hinges 5 and duckbill locks 6, which facilitates maintenance and inspection work. The structure of the rain cover 2 takes into account wind pressure resistance and load-bearing capacity to ensure stability under adverse weather conditions. The structural design of the rain cover 2 also takes into account aesthetics, coordinates with the overall prefabricated cabin, and enhances the overall visual effect.

[0034] The strip-type air filter bag 3 in the present invention can prevent dust and other particulate matter from entering the interior of the cabin shell 1, protect the equipment in the cabin shell 1 from pollution, and extend the service life of the equipment. Reducing dust accumulation can improve the heat dissipation efficiency of the equipment in the cabin shell 1, thereby improving overall energy efficiency. In certain environments where anti-static measures are required, the strip-type air filter bag 3 can reduce the generation of static electricity, protect sensitive equipment, effectively block the wind from blowing up dust from the ground, and reduce suspended particulate matter in the air. The installation is relatively simple and the maintenance cost is low. The material is durable, has a high dust holding capacity, can be reused, and reduces waste. It can be customized according to the size and shape of the area to be covered, and has good adaptability.

[0035] The barrier inner cover 4 in the present invention can prevent the inserted air filter bag 3 from touching the electrical equipment and ensure the circulation of air. The barrier inner cover 4 is made of retired fan blades to reduce the impact of waste on the environment and conform to the concept of sustainable development. The reuse of retired fan blades can reduce the cost of making the barrier inner cover 4. Fan blades are usually made of durable epoxy resin material with high strength and durability. Therefore, they can have a long service life when used as barrier inner cover 4 and can ensure the insulation of the power transmission and transformation equipment in the cabin shell 1. Due to the durability of the fan blades, the modified barrier inner cover 4 requires less maintenance, reduces long-term operating costs, and can improve safety.

[0036] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
