Description

Technical Field

[0001] The invention relates to the technical field of dustproof sheds, and in particular to a GIS dustproof shed. Background Art

[0002] GIS dustproof shed is a special structure used to protect gas-insulated switchgear and its accessories, and is usually used to reduce the impact of the external environment on the operation of GIS equipment. Dustproof sheds are mainly used in outdoor or semi-enclosed installation environments to provide additional protection to prevent dust, sand, rain and other impurities from polluting and damaging the equipment, thereby improving the reliability and life of the equipment. Dustproof sheds can effectively reduce the dust and particulate matter in the air from adhering to the surface of GIS equipment and reduce the degradation rate of insulating materials. It is very important to prevent direct invasion of equipment by rain, strong wind, ice and snow, especially in coastal, industrial or desert areas with high corrosiveness. Dustproof sheds are usually composed of metal frames and weather-resistant materials, which can withstand large wind loads and other natural forces. While maintaining the dustproof effect, ventilation and heat dissipation in the shed are considered to avoid the adverse effects of high temperature on the equipment. The design of dustproof sheds is usually easy to disassemble and clean, which is convenient for equipment inspection and maintenance. According to different site conditions and GIS equipment models, dustproof sheds can be customized to meet special needs.

[0003] Since the strength of the air column can only barely support the outer tarpaulin, it is difficult to carry it without deformation. The large size makes it inconvenient to move. Environmental monitoring devices are generally not integrated into the dustproof shed structure but are external, which not only gets in the way but also makes it difficult for the detection point to provide timely and comprehensive feedback on the internal environment of the dustproof shed.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a GIS dustproof shed to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and design a GIS dustproof shed that enhances the strength of traditional air columns while reducing the volume when stored, thereby improving the portability of the dustproof shed and providing comprehensive feedback on the internal environment of the dustproof shed during operation.

[0006] In order to solve the above technical problems, the present invention is implemented by adopting the following technical solutions: A GIS dustproof shed includes a base fabric structure, an air column structure, an outer tarpaulin structure, a filter ring structure, a top suction detection structure and a splicing zipper. The dustproof shed is compact and lightweight and suitable for a variety of scenarios. The base fabric structure is located at the bottom of the dustproof shed to provide basic support and stability; the air column structure is arranged inside the base fabric structure and forms the main frame of the shed through inflation, which has the advantage of rapid construction and disassembly. The outer tarpaulin structure covers the outer side and top surface of the air column structure to prevent dust, rain and sun, and a door is reserved on the side to facilitate the entry and exit of equipment and personnel.

[0007] To improve the dust-proof effect, a filter ring structure is installed on the periphery of the base fabric structure, which can effectively block the intrusion of external dust and particulate matter and ensure the cleanliness of the internal environment. A top suction detection structure is set in the center of the outer tarpaulin structure on the top, which integrates real-time monitoring functions such as temperature, humidity, and dust concentration. It transmits internal environmental data through wireless transmission to facilitate timely adjustment and management. The splicing zipper connects the outer tarpaulin structure and the base fabric structure, making the overall structure more sealed and convenient for quick disassembly and assembly. This dustproof shed is not only easy to transport and install, but also provides comprehensive environmental protection through efficient monitoring technology. It is a practical and innovative solution.

[0008] Preferably, the air column structure comprises an air column sleeve, a bellows and a support sleeve; the air column sleeve is arranged inside the outer tarpaulin structure, the bellows is arranged in the middle of the air column sleeve, and the support sleeve is installed inside the air column sleeve.

[0009] Preferably, the air column structure further includes a telescopic sleeve and a limit block; The two ends of the telescopic sleeve are installed inside the supporting sleeve, and the annular array of limit blocks is arranged at the two ends of the outer side of the supporting sleeve.

[0010] Preferably, the gas column structure further includes a support column and a gas flow channel; The support column is installed between the gas column sleeve and the support sleeve, the gas flow channel is opened on the side of the support sleeve, and the cross-sectional shape of the gas flow channel is set to be radial.

[0011] Preferably, the air column structure further includes a limiting sliding groove and a top ring groove; The limiting sliding groove is arranged on the inner side surface of the supporting sleeve, and the top ring groove is arranged on the top ends of both sides of the limiting sliding groove.

[0012] Preferably, the cross-sectional shape of the limiting sliding groove is set to be a fan ring.

[0013] Preferably, the base fabric structure includes a ground-contacting base fabric, a peripheral annular base fabric and hook-surface Velcro; The ground-contacting base fabric is arranged as the lower part of the base fabric structure, the peripheral annular base fabric is installed at the periphery of the ground-contacting base fabric, and the hook-surface Velcro is installed at the upper and lower parts of the outer side surface of the peripheral annular base fabric.

[0014] Preferably, the material of the ground-contacting base fabric is set to be airtight and airtight waterproof cloth, and the material of the peripheral annular base fabric is set to be gauze with good air permeability. Preferably, the filter ring structure comprises a sponge strip, an outer cloth cover, a fleece Velcro and an air bag; The sponge strip is installed at the bottom of the outer tarpaulin structure, the outer surface of the sponge strip is wrapped with an outer cloth cover, the upper and lower parts of the inner side of the outer cloth cover are sewn with fleece Velcro, and an air bag is arranged inside the sponge strip.

[0015] Preferably, the top suction detection structure includes a top fan and a top environment detector; the top fan is installed on the top of the outer tarpaulin structure, and the top environment detector is installed below the top fan. The top suction detection structure is connected to the middle position of the top of the outer tarpaulin structure by Velcro. When the top fan is working, the air inside the dustproof shed can be sucked out, and at the same time, the external air enters the dustproof shed after being filtered by the filter ring structure. The top environment detector can check the humidity and temperature of the air inside the dustproof shed and other data that need to be detected. Since the top environment detector is located at the center above the dustproof shed and the air flows upward from the filter ring structure around the bottom of the dustproof shed, the data detected by the top environment detector is relatively comprehensive and timely, so the top environment detector can effectively and timely feedback the air quality inside the dustproof shed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides an air column structure in combination with a filter ring structure, giving full play to the advantages of portability and environmental adaptability. When stored, the air column structure can be shrunk by adjusting the air pressure, thereby greatly reducing the volume of the overall device and facilitating storage and transportation. This design greatly improves the portability of the dustproof shed, making it suitable for a variety of occasions, especially for environments that require frequent transportation or are space-constrained. The shrunk air column structure can effectively save space and reduce transportation and storage costs. The air column structure forms a high-strength and stable frame through the combination of a sturdy support sleeve and bracket column with a flexible and wear-resistant air column sleeve. This structure can remain highly stable when subjected to external pressure and airflow changes, ensuring the long-term use and strong load-bearing capacity of the dustproof shed in practical applications. The support sleeve and bracket column provide stable support for the air column, avoiding the risk of structural deformation or collapse, thereby ensuring the safety of the dustproof shed in severe weather or complex environments.

[0017] (2) The air column structure is combined with the filter ring structure, so that the entire dustproof shed has stronger environmental adaptability. The filter ring can effectively block the intrusion of external dust, sand or harmful substances, prevent air pollution in the shed, and ensure the cleanliness of the internal environment. This design enables the dustproof shed to maintain excellent protection performance under different climatic conditions and environments, which not only improves its adaptability, but also increases its reliability in harsh conditions. This structural design takes into account portability, stability and environmental adaptability, giving the dustproof shed significant advantages in transportation, storage and actual use, and meets the needs of a variety of application scenarios.

[0018] (3) The present invention is provided with a top fan and a top environmental detector to achieve more efficient air circulation and environmental monitoring. The working principle of the top fan is to draw the air inside the dustproof shed outward, which can not only timely discharge the exhaust gas, moisture and pollutants in the shed, but also prevent the air from being trapped in the shed and keep the air circulation smooth. At the same time, the fresh air from the outside enters the dustproof shed after being filtered by the filter ring structure, ensuring that the outside air is cleaned and pollutants are prevented from directly entering, thereby maintaining the air quality in the shed. The top environmental detector can monitor the air quality data such as humidity and temperature in the shed in real time. Since the air in the shed flows from the filter ring structure around the bottom to the top, the air data received by the detector is comprehensive and timely. This arrangement ensures that the top environmental detector can accurately sense the air conditions in the entire dustproof shed, not just the environmental changes in the local area. Therefore, the top environmental detector can timely feedback the quality of the air inside the dustproof shed, helping users to make corresponding adjustments based on real-time data.

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] like Figure 1-9 As shown, a GIS dustproof shed includes a base fabric structure 1, an air column structure 2, an outer tarpaulin structure 3, a filter ring structure 4, a top suction detection structure 5 and a splicing zipper 6. The dustproof shed is compact and lightweight and suitable for a variety of scenarios. The base fabric structure 1 is located at the bottom of the dustproof shed to provide basic support and stability; the air column structure 2 is arranged inside the base fabric structure 1, and the main frame of the shed is formed by inflation, which has the advantage of rapid construction and disassembly. The outer tarpaulin structure 3 covers the outer side and top surface of the air column structure 2, which plays a role in dustproof, rainproof and sunshade. A door 301 is reserved on the side to facilitate the entry and exit of equipment and personnel.

[0024] In order to improve the dustproof effect, a filter ring structure 4 is installed on the periphery of the base fabric structure 1, which can effectively block the invasion of external dust and particulate matter and ensure the cleanliness of the internal environment. A top suction detection structure 5 is set in the center of the outer tarpaulin structure 3 on the top, which integrates real-time monitoring functions such as temperature, humidity, and dust concentration, and feeds back internal environmental data through wireless transmission, which is convenient for timely adjustment and management. The splicing zipper 6 connects the outer tarpaulin structure 3 and the base fabric structure 1, making the overall structure more sealed and convenient for quick disassembly and assembly. This dustproof shed is not only easy to transport and install, but also provides comprehensive environmental protection through efficient monitoring technology. It is a practical and innovative solution.

[0025] like Figure 4 As shown, the air column structure 2 is composed of an air column sleeve 201, a bellows 202 and a support sleeve 203, and each part is closely combined to form a stable support system. The air column sleeve 201 is located inside the outer tarpaulin structure 3, and is inflated to form a columnar frame, which plays a role in supporting and fixing the outer tarpaulin. The bellows 202 is arranged in the middle part of the air column sleeve 201, and has good flexibility and compressibility, which can help the air column structure 2 to expand and contract, improve the adaptability of the air column structure 2, and enhance the wind resistance and deformation resistance of the overall structure. The support sleeve 203 is installed inside the air column sleeve 201 and is made of high-strength material to further improve the rigidity and bearing capacity of the air column. Through this multi-layer design, the air column structure 2 not only has the characteristics of rapid construction, but also can ensure that the dustproof shed remains stable in a variety of complex environments, prolongs its service life, and provides reliable support performance.

[0026] like Figure 5 As shown, the air column structure 2 also includes a telescopic sleeve 204 and a limit block 205 to further enhance the flexibility and stability of the structure. The telescopic sleeve 204 is installed inside the support sleeve 203 and has an adjustable length. The length of the air column can be adjusted as needed to ensure that the structure can adapt to changes in different environments. The two ends of the telescopic sleeve 204 are connected to the support sleeve 203, so that the entire air column structure 2 can achieve better adjustment and extensibility. The limit blocks 205 are arranged in a circular array at both ends of the outer side of the support sleeve 203, which prevents the telescopic sleeve 204 from over-stretching or contracting, ensuring that the air column remains stable during inflation and avoiding structural deformation or damage caused by excessive stretching. Through the coordinated use of the telescopic sleeve 204 and the limit blocks 205, the stability and reliability of the air column structure 2 are further improved.

[0027] like Figure 6-8As shown, the air column structure 2 also includes a support column 206 and a gas flow channel 209, which further improves the overall support performance and the uniformity of the air flow distribution. The support column 206 is installed between the air column sleeve 201 and the support sleeve 203, and plays a role in connection and reinforcement, so that the air column structure 2 remains stable while carrying the outer tarpaulin. The support column 206 is made of high-strength lightweight material to ensure that the pressure resistance is significantly improved without increasing the weight of the structure. The gas flow channel 209 is opened on the side of the support sleeve 203, and its cross-sectional shape is designed to be radial. By optimizing the air flow distribution, the inflation efficiency and the overall uniformity of the air column are improved. This radial design can effectively avoid the problem of uneven local pressure and ensure that the entire air column structure 2 is quickly formed and stably supported during the inflation process. The combined design of the support column 206 and the gas flow channel 209 enables the air column structure 2 to have higher adaptability and reliability, meeting the needs of complex use environments.

[0028] like Figure 6 As shown, the air column structure 2 also includes a limiting slide groove 207 and a top ring groove 208 to improve the precise positioning and stability of the air column structure 2 during the telescopic process. The limiting slide groove 207 is arranged on the inner side of the support sleeve 203, and its function is to provide guidance for the movement of the telescopic sleeve 204, and at the same time prevent the overall stability of the air column from being affected by excessive offset or dislocation. Through the restriction of the limiting slide groove 207, the components inside the air column can maintain stable operation during the extension and shortening process, ensuring the reliability of the structure. The top ring groove 208 is opened at the top of both sides of the limiting slide groove 207 to provide positioning and fixing for the top components. The ring groove is arranged at both ends of the limiting slide groove 207 to help the telescopic sleeve 204 to be fixed, which not only enhances the stability of the top connector, but also can effectively disperse the stress of the top to avoid structural damage caused by excessive local force. The mutual cooperation between the limiting slide groove 207 and the top ring groove 208 makes the air column structure 2 more compact and stable, and at the same time improves its applicability and durability under various environmental conditions.

[0029] The cross-sectional shape of the limiting slide groove 207 is set to be a fan ring, and the fan ring cross-section can disperse the pressure more evenly, so that the slide groove remains stable when subjected to external forces (such as the internal air pressure of the air column or the external environmental load), and is not easy to deform or damage. This shape is particularly suitable for bearing multi-directional stress distribution and improving overall durability.

[0030] like Figure 3As shown, the base fabric structure 1 includes a ground-attached base fabric 101, a peripheral annular base fabric 102 and a hook-surface Velcro 103, and each part cooperates with each other to ensure the stability and sealing performance of the dustproof shed. The ground-attached base fabric 101 is the core part of the base fabric structure 1, which is directly laid on the ground to provide basic support for the entire dustproof shed. At the same time, it has an anti-slip design to enhance the contact stability with the ground. The peripheral annular base fabric 102 is installed around the ground-attached base fabric 101 and connected with other components to form an overall sealing effect. The annular base fabric is made of wear-resistant material and can effectively prevent external dust and moisture from invading. The hook-surface Velcro 103 is arranged on the upper and lower sides of the outer side of the peripheral annular base fabric 102. By using it in conjunction with the corresponding annular Velcro, it can achieve fast and firm assembly, which is easy to install and disassemble. This design takes into account the strength, airtightness and ease of operation of the base fabric structure 1, and meets the protection needs in complex environments.

[0031] The material of the bottom cloth 101 attached to the ground is a sealed and airtight waterproof cloth, which is intended to provide a solid basic protection for the dustproof shed. This waterproof cloth has excellent moisture-proof performance, which can effectively block the intrusion of water vapor, moisture and dust on the ground. At the same time, it has the characteristics of strong wear resistance and excellent tear resistance, ensuring that it is not easily damaged during long-term use under complex terrain conditions. The peripheral annular bottom cloth 102 is made of gauze material with good air permeability, and its design is mainly used to enhance the internal air circulation effect. This gauze material has good air permeability while maintaining strength and durability, which can help regulate the temperature and humidity inside the dustproof shed and avoid adverse environments caused by excessive sealing. The combination of these two materials enables the bottom cloth structure 1 to provide reliable sealing protection and effectively meet the requirements of environmental comfort, ensuring that the dustproof shed can operate stably under various working conditions.

[0032] like Figure 3 As shown, the filter ring structure 4 includes a sponge strip 401, an outer cloth cover 402, a fleece Velcro 403 and an airbag 404, and each part cooperates closely to form an efficient filtering system. The sponge strip 401 is installed at the bottom of the outer tarpaulin structure 3, and as the main filtering and sealing material, it can effectively absorb dust and impurities in the air. The outer surface of the sponge strip 401 is wrapped with an outer cloth cover 402, and the cloth cover is made of durable and breathable materials to further enhance the filtering effect and protect the sponge strip 401 from damage. The upper and lower sides of the inner side of the outer cloth cover 402 are sewn with fleece Velcro 403 by needle and thread, so that the outer cloth cover 402 can be quickly fixed and disassembled with other structural parts, which is convenient for maintenance and cleaning. An airbag 404 is arranged inside the sponge strip 401, which can provide additional support after inflation, so that the filter ring maintains a stable shape during operation, and can effectively compress the air flow and improve the filtering efficiency. The overall design ensures that the dustproof shed can continuously and effectively filter harmful substances in the air under different environments.

[0033] like Fig. 9 As shown, the top suction detection structure 5 is composed of a top fan 501 and a top environment detector 502, which is intended to effectively monitor and adjust the air quality inside the dustproof shed. The top fan 501 is installed on the outer tarpaulin structure 3. Its main function is to discharge the air inside the dustproof shed to the outside through exhaust to keep the air flowing in the shed. This design can prevent air stagnation, help discharge harmful gases or excessive temperatures that may accumulate inside, and ensure that the internal environment of the dustproof shed always remains fresh. At the same time, the external air enters the dustproof shed after passing through the multi-layer filtration of the filter ring structure 4. The filter ring structure 4 can effectively block external dust, dust and harmful particles to ensure the cleanliness of the air in the shed.

[0034] The top environment detector 502 is installed below the top fan 501, located in the upper center of the dustproof shed. The monitor can detect the temperature, humidity and other air quality indicators in the shed in real time. Since the air circulation inside the dustproof shed flows upward from the filter ring structure 4 around the bottom, the air data received by the top environment detector 502 is usually more comprehensive and timely. The bottom monitor can capture the overall state of the air in the shed and promptly feedback key information such as temperature, humidity, and dust concentration. Real-time monitoring of these data enables users to quickly understand the environmental conditions of the dustproof shed and take corresponding measures.

[0035] Through this design, the top suction detection structure 5 can not only effectively adjust the circulation and quality of the internal air, but also start the fan or other systems when necessary to further optimize the environment in the shed. The real-time data feedback of the top environment detector 502 provides an important basis for the automatic control system of the dustproof shed, enabling it to better respond to environmental changes, maintain efficient protection performance, and ensure that the air quality inside and outside the dustproof shed remains within the safety standard.

[0036] During the working process of the present invention, the air column structure 2 for preventing shrinkage needs to be unfolded and used first: The bellows 202 is used to squeeze and rotate the telescopic sleeve 204, so that the limit blocks 205 at both ends are inserted into the limit sliding groove 207 from the top ring groove 208 on the outside of the gas column ceramics on both sides, and the bellows 202 in the superimposed contraction state is straightened, so that the gas column sleeves 201 on both sides of the bellows 202 are separated to the maximum distance, and the limit blocks 205 set on the telescopic sleeve 204 are moved in the limit sliding groove 207 to the top ring groove 208 set on the inner side of the gas column sleeves 201 on both sides, and the bellows 202 is squeezed and rotated again to fix it. This operation is repeated many times, and the gas column structure 2 is installed. The high-pressure gas is transported in the gas column sleeve 201 through an external gas pump. The high-pressure gas enters from the support sleeve 203 and enters the gas column sleeve 201 through other flow channels, and cooperates with the support rod to achieve high-strength structural support; The outer surface of the sponge strip 401 is wrapped with an outer cloth cover 402 with good air permeability. The upper and lower parts of the inner side of the outer cloth cover 402 are connected with a fleece Velcro 403 by sewing. The interior of the sponge strip 401 is provided with an air bag 404. The interior of the air bag 404 can withstand very high air pressure and has a small expansion coefficient. After the air bag 404 is injected with high-pressure air, the filter ring structure 4 can have a higher strength, and the use stability of the overall structure is further enhanced by cooperating with the air column structure 2. The filter ring structure 4 is used as a supporting structure to improve the bottom strength of the dustproof shed and prevent deformation. When the gas enters the interior of the outer tarpaulin structure 3 from the filter ring structure 4, the other parts are initially filtered to ensure the detection accuracy of the GIS device and the top environment detector 502; The top environment detector 502 can detect the temperature, humidity and other air quality indicators in the shed in real time. Since the air circulation inside the dustproof shed flows upward from the filter ring structure 4 around the bottom, the air data received by the top environment detector 502 is usually more comprehensive and timely. The bottom monitor can capture the overall state of the air in the shed and provide timely feedback on key information such as temperature, humidity, and dust concentration. Real-time monitoring of these data enables users to quickly understand the environmental conditions of the dustproof shed and take corresponding measures.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
