Description

Technical Field

[0001] This application relates to the technical field of circuit breaker storage, and in particular to a storage device for floor-mounted circuit breakers. Background Technology

[0002] Ground-mounted circuit breakers are key protection and control devices in power systems and are widely used in various fields such as industrial production, power transmission, and building power distribution.

[0003] As attached Figure 1 The diagram shows a three-dimensional structural schematic of a ground-mounted circuit breaker, which includes a circuit breaker body 1. The bottom of the circuit breaker body 1 is provided with a sliding pulley 13. A fixed frame 11 is provided on one side of the circuit breaker body 1. The two ends of the fixed frame 11 are respectively provided with movable positioning pins 12. At present, the industry mostly uses the method of directly exposing ground-mounted circuit breakers for storage. At most, the stylus contacts are covered with a dustproof plastic bag. There is a lack of targeted special storage devices. Although this extensive storage mode can temporarily meet the storage needs in ordinary environments, in the humid saline-alkali areas of the south, the air not only contains high water vapor, but may also contain saline-alkali components produced by soil, seawater evaporation or industrial activities, forming corrosive gases (such as gaseous compounds containing chloride ions, sodium ions, etc., water vapor, etc.).

[0004] When floor-mounted circuit breakers are placed directly on the ground, moisture from the ground can easily seep upwards, causing condensation on the surface of the circuit breaker and damaging the protective layer on the equipment surface. On the other hand, key metal components such as contact switches and terminals on the circuit breaker will come into direct contact with corrosive gases in the air. These corrosive gases react with the metal surface through chemical action, gradually damaging the contact performance of the contact switches and reducing conductivity, thus failing to guarantee the storage quality of the circuit breaker in special environments. Summary of the Invention

[0005] To improve the storage life of circuit breakers in various environments, a storage device for floor-mounted circuit breakers is provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: A storage device for a floor-mounted circuit breaker includes a cabinet for housing the circuit breaker body, and further includes: A purification component is used to purify the gas inside the cabinet. The limiting component includes a limiting slide and a positioning hole. The limiting slide is fixed to the bottom of the cabinet and provides sliding space for the pulley of the circuit breaker body. The positioning hole is opened on the inner wall of both sides of the cabinet and provides limiting space for the positioning pin of the circuit breaker body.

[0007] By adopting the above technical solutions, the cabinet provides a closed storage space for the floor-standing circuit breaker, which can isolate the circuit breaker from direct contact with external humid air and corrosive gases, and prevent ground moisture from seeping upwards. The purification component can actively purify the gas inside the cabinet, removing moisture and corrosive components, solving the problems of gas corrosion and moisture erosion in traditional extensive storage. In the limiting component, the limiting slide provides directional sliding space for the pulleys of the circuit breaker body, facilitating the circuit breaker to enter and exit the cabinet, while the positioning hole can fix the positioning pin of the circuit breaker, preventing the circuit breaker from shaking and colliding inside the cabinet, reducing the corrosion of the circuit breaker by adverse external environmental factors, and extending the storage life of the circuit breaker in complex environments.

[0008] Preferably, support brackets are also fixed on the inner walls of both sides of the cabinet. The support brackets include a push-limiting plate for limiting the circuit breaker body and a support plate for supporting the fixed frame of the circuit breaker body.

[0009] By adopting the above technical solution, the support brackets on both sides of the inner wall of the cabinet directly support the fixed frame of the circuit breaker. The support brackets distribute the overall weight of the circuit breaker, avoiding excessive stress on a single point between the positioning pin on the fixed frame of the circuit breaker and the storage cabinet, thus enhancing storage stability; the push limit plate prevents the circuit breaker from overtraveling during the push process.

[0010] Preferably, the end of the support bracket that abuts against the circuit breaker body is provided with an arc-shaped guide portion.

[0011] By adopting the above technical solution, the arc-shaped structure has a smooth transition characteristic. When the circuit breaker is pushed into the cabinet, its fixed frame will first contact the arc-shaped guide surface and then contact the push-in limiting surface. The guide part can guide the frame to move smoothly in the correct direction, avoiding hard jamming or friction between the support end and the frame.

[0012] Preferably, it also includes a foldable guide component, the guide component including a foldable slide rail disposed opposite to the limiting slide rail.

[0013] By adopting the above technical solution, the folding slide rail in the guide component is aligned with the limiting slide rail at the bottom of the cabinet to form a continuous sliding channel. Before entering the cabinet, the pulley of the circuit breaker can rest on the folding slide rail and move smoothly along the direction of the slide rail. It can smoothly enter the cabinet without the need for manual precise alignment of the limiting slide rail, reducing the difficulty of alignment during storage and retrieval.

[0014] Preferably, the guide assembly further includes a connecting part fixed to the bottom of the cabinet, the connecting part being hinged with a folding adapter, and the top of the folding slide rail being hinged to the top of the folding adapter.

[0015] By adopting the above technical solution, the folding adapter can rotate freely around the hinge point and can be folded and stored in the cabinet. The folding slide rail can also rotate freely around the hinge point and can be folded and stored in the folding adapter, reducing the overall space occupied by the device. No additional slide rail needs to be installed during use. During use, the tilt angle of the folding adapter can be adjusted according to the actual scenario such as the flatness of the ground and the placement height of the circuit breaker to ensure a smooth transition between the slide rail and the limit slide and the ground, adapting to different storage environments.

[0016] Preferably, a limiting block for limiting the pulley is fixedly provided at the end of the limiting slide.

[0017] By adopting the above technical solution, the limit block directly blocks the pulley of the circuit breaker body from continuing to move forward, forming a mechanical stop. This prevents the circuit breaker from overtraveling due to excessive pushing force when it is pushed into the cabinet, and prevents key components such as the circuit breaker's stud contacts and fixed frame from colliding with the internal structure of the cabinet, thus eliminating the risk of component deformation and damage.

[0018] Preferably, the purification components are provided in several groups and are located above and below the cabinet respectively.

[0019] By adopting the above technical solution, a multi-directional gas purification coverage is formed. The upper purification component can handle the gas in the upper space of the cabinet, and the lower purification component can handle the gas in the lower space, avoiding gas circulation dead zones caused by purification in a single location, and ensuring that the gas in each area of ​​the cabinet can be included in the purification process.

[0020] Preferably, the cabinet body is hinged to a cabinet door, and the cabinet body is provided with a micro switch that is triggered by the cabinet door, and the micro switch is electrically connected to the purification component.

[0021] By adopting the above technical solution, when the cabinet door is closed, squeezing the micro switch will close it and the purification component will start working; when the cabinet door is opened, the micro switch will reset and open, and the purification component will stop running, realizing intelligent start-stop control of the purification component, saving energy consumption, and ensuring that the purification component functions in an effectively sealed environment.

[0022] Preferably, the purification component includes a purification box and a fan. The purification box is provided with an adsorbent hanging bag rack for hooking the adsorbent. The two ends of the purification box are respectively opened with an air inlet and an air outlet that are connected to the cabinet body. The fan is aligned with the air inlet of the purification box, and the purification box is also provided with adsorbent cotton for adsorbing impurities at the air inlet.

[0023] By adopting the above technical solution, the fan in the purification component can drive the gas inside the cabinet to form a circulating airflow, guiding the gas into the purification box through the air inlet; the adsorption cotton at the air inlet first filters out solid impurities such as dust in the gas, preventing impurities from adhering to key components such as circuit breaker contacts and wiring terminals; the adsorbent hanging bag rack inside the purification box is used to fix the adsorbent. When the gas passes through the adsorbent, the water vapor and corrosive components (such as chloride ions, sodium ions, etc.) in it are adsorbed and removed. The purified gas is discharged from the air outlet back into the cabinet, forming a complete purification cycle, achieving dual purification of the gas inside the cabinet by filtering solid impurities and adsorbing water vapor and corrosive components.

[0024] Preferably, the purification assembly further includes a heater for heating the gas, and the heater is aligned with the gas outlet of the purification box.

[0025] By adopting the above technical solution, the purified gas is heated when it passes through the heater. The relative humidity of the gas decreases after the temperature rises, which can further remove residual water vapor in the gas. At the same time, the warm gas will form natural convection in the cabinet, which will accelerate the gas circulation in the cabinet and make the purification effect of the purification components more comprehensive.

[0026] In summary, this application has at least the following beneficial effects: 1. The cabinet and hinged doors form a closed storage space. With the micro-switch linked to the cabinet door, the purification components can be intelligently started and stopped. This ensures the airtightness of the storage environment to prevent the direct intrusion of external humid air and corrosive gases, while avoiding ineffective energy consumption. Multiple purification components are located on the upper and lower parts of the cabinet. Combined with the adsorption cotton, adsorption bag rack, fan and heater in the purification box, a multi-stage purification process is formed, which filters impurities, adsorbs corrosive components, dehumidifies and circulates gas. This process can cover all areas of the cabinet, remove solid impurities, water vapor and corrosive components such as chloride ions and sodium ions from the gas, reduce the risk of condensation on the surface of the circuit breaker, and prevent damage to its protective layer and chemical corrosion and performance degradation of key components such as contact switches and terminals. 2. The limiting component, support bracket, and guide component work together to provide a directional sliding path for the circuit breaker's pulleys, allowing for smooth storage and retrieval without the need for precise manual alignment. The positioning holes fix the circuit breaker in place, while the support bracket distributes the force, preventing shaking, collisions, deformation, or scratches caused by uneven force during storage. Furthermore, the foldable guide rail can adapt to different ground surfaces and save idle space, improving the convenience and adaptability of storage and retrieval operations.

Detailed implementation method: The following section provides a more detailed description, in conjunction with the accompanying diagrams: As attached Figure 2 and attached Figure 3 As shown, a storage device for floor-standing circuit breakers includes a cabinet 2 for storing floor-standing circuit breakers. The cabinet 2 is made of cold-rolled steel plate and is rectangular in shape. Its length, width and height are designed according to the specifications of common floor-standing circuit breakers to ensure that the cabinet 2 can fully accommodate the circuit breakers.

[0028] A cabinet door 21 is hinged to one side of the cabinet body 2. The material of the cabinet door 21 is the same as that of the cabinet body 2. A rubber sealing strip is attached to the edge of the cabinet door 21. When the cabinet door 21 is closed, the sealing strip can fill the gap between the cabinet door 21 and the cabinet body 2, enhance the airtightness of the cabinet body 2, and reduce the entry of external air into the cabinet.

[0029] As attached Figure 1 and attached Figure 3 As shown, the cabinet 2 is also equipped with a limiting component 3, a guiding component 5, and a purification component 6. The limiting component 3 includes two limiting slides 31, which are parallel and symmetrically fixed on the bottom inner wall of the cabinet 2. They are made of metal, have a U-shaped cross section, and the opening faces upward. The spacing of the limiting slides 31 matches the spacing of the pulleys 13 at the bottom of the circuit breaker body 1. The length of the slide is consistent with the internal length of the cabinet 2. The inner wall of the limiting slides 31 is polished smooth to reduce the friction when the pulleys 13 slide. The ends of the two limiting slides 31 are also fixed with limiting blocks 32 to restrict the pulleys 13 from continuing to move forward, forming a mechanical stop. The limiting slides 31 provide directional sliding space for the pulleys 13 of the circuit breaker body 1, so that the circuit breaker can enter and exit the cabinet 2 along a fixed trajectory and avoid deviation during the sliding process.

[0030] Two sets of positioning holes 33 are provided on the inner walls of both sides of the cabinet 2 along the length direction perpendicular to the limiting slide 31. There are two holes in each set, symmetrically distributed on the inner walls of both sides. The diameter of the positioning hole 33 is adapted to the diameter of the positioning pin 12 on the circuit breaker body 1, and the position corresponds to the position of the positioning pin 12 after the circuit breaker is pushed into the cabinet 2. When the circuit breaker is pushed into the cabinet 2 to the preset storage position along the limiting slide 31, the positioning pin 12 on the circuit breaker can be inserted into the corresponding positioning hole 33. The positioning hole 33 constrains the positioning pin 12, restricting the circuit breaker from moving back and forth and left and right in the cabinet, preventing the circuit breaker from colliding due to shaking.

[0031] Two support brackets 4 are fixed on the inner walls of both sides of the cabinet 2. The two support brackets 4 are symmetrically distributed on the inner walls of both sides and are located at two sets of positioning holes 33. The support bracket 4 is L-shaped and consists of a vertical push-limit plate 41 and a horizontal support plate 42. When the circuit breaker is pushed into the cabinet 2 and positioned by the limit component 3, the bottom of the circuit breaker's fixing frame 11 will abut against the horizontal support plate 42. The support bracket 4 can share part of the weight of the circuit breaker, avoiding the weight of the circuit breaker being borne solely by the positioning pin 12 and pulley 13, and preventing the positioning pin 12 from deforming due to excessive force at a single point. The push-limit plate 41 is set to prevent the circuit breaker from overtravel during the push-in process. The harm of overtravel is that it may cause the circuit breaker's sprite contact to collide with the rear of the cabinet 2, resulting in damage to the circuit breaker's sprite contact or other components.

[0032] The horizontal support plate 42 has an integrally formed arc-shaped guide part 43 at the end near the opening side of the cabinet 2. The arc of the guide part 43 is 1 / 4 arc and the surface is polished. The arc surface of the arc-shaped guide part 43 faces the opening direction of the cabinet 2. When the circuit breaker is pushed into the cabinet 2, the front end of its fixing frame 11 will first contact the surface of the arc-shaped guide part 43, guiding the fixing frame 11 to move smoothly along the top plane of the horizontal support plate 42.

[0033] Two sets of guide components 5 are provided here and are located at two limiting slides 31 respectively. The guide component 5 includes a folding slide rail 51, which is made of metal, has a U-shaped cross section, and faces upward. One end of the folding slide rail 51 is aligned with the limiting slide 31 at the bottom of the cabinet 2, and the end face of this end is in contact with the end face of the limiting slide 31, ensuring that the folding slide rail 51 and the limiting slide 31 form a continuous sliding channel. The other end of the folding slide rail 51 abuts against the ground. Before entering the cabinet 2, the pulley 13 of the circuit breaker can roll smoothly along the direction of the folding slide rail 51, and can smoothly enter the interior of the cabinet 2 without the need for manual precise alignment with the limiting slide 31.

[0034] As attached Figure 3 and attached Figure 4As shown, the guide assembly 5 also includes a connecting part 52 and a folding adapter 53. The connecting part 52 is an L-shaped metal bracket, which is fixed to the outer side wall of the bottom of the cabinet 2 by bolts or welding. The connecting part 52 is located inside the cabinet 2 and on one side of the limiting slide rail 31. The material of the folding adapter 53 is the same as that of the folding slide rail 51. The opening of the folding adapter 53 faces upward. The end of the folding adapter 53 is hinged to the connecting part 52 through a hinge shaft. The folding adapter 53 can be flipped around the hinge shaft. The top of the end of the folding slide rail 51 away from the cabinet 2 is hinged to the top of the folding adapter 53 through a hinge shaft, so that the folding slide rail 51 can be flipped around the hinge shaft.

[0035] When not in use, the folding slide rail 51 can be flipped around the top hinge axis to the top of the folding adapter 53, and then the folding adapter 53 can be flipped around the bottom hinge axis to the bottom of the cabinet 2 and stored under the cabinet 2 to reduce the overall space occupied by the device. When in use, the tilt angle of the folding adapter 53 can be adjusted according to the flatness of the ground and the placement height of the circuit breaker so that the bottom of the folding adapter 53 contacts the ground, forming a smooth transition from the ground to the folding slide rail 51 and then to the limiting slide rail 31.

[0036] As attached Figure 3 and attached Figure 5 As shown, there are four sets of purification components 6. Two sets are symmetrically installed on the inner wall of the top of the cabinet 2, and two sets are symmetrically installed on the side wall of the bottom of the cabinet 2. Each set of purification components 6 corresponds to a different area inside the cabinet 2, ensuring that the gas inside the cabinet can be completely purified and avoiding purification dead zones.

[0037] The purification component 6 includes a purification box 61, which is a rectangular metal box fixed to the inner wall of the cabinet 2 by bolts. The purification box 61 has an air inlet 611 and an air outlet 612 at both ends, respectively, which communicate with the interior of the cabinet 2. Inside the purification box 61, there is also an adsorbent bag holder 62 for hanging the adsorbent. The adsorbent bag holder 62 is a metal frame structure, welded and fixed inside the purification box 61, located between the air inlet 611 and the air outlet 612. The adsorbent bag holder 62 has 4-6 hooks evenly distributed on it for hanging bags containing adsorbent. The adsorbent is a mixture of activated carbon and molecular sieve particles, which can effectively adsorb water vapor and corrosive components such as chloride ions and sodium ions in the gas. The number of adsorbent bags matches the number of hooks, and gaps are left between the bags to ensure that the gas can fully pass through the adsorbent, improving the adsorption effect.

[0038] An absorbent cotton 63 is fixed inside the air inlet 611 of the purification box 61. The absorbent cotton 63 can filter out solid impurities such as dust and particulate matter in the gas. A heater 65 is fixed outside the air outlet 612 of the purification box 61. The heater 65 is a small electric heater. After the purified gas is discharged from the air outlet 612, it is heated by the heating surface of the heater 65. The relative humidity of the gas decreases after the temperature rises.

[0039] A fan 64 is fixedly installed on the outside of the air inlet 611 of the purification box 61. The air outlet of the fan 64 is aligned with the air inlet 611 of the purification box 61 to ensure that the airflow can smoothly enter the purification box 61. When the fan 64 is working, it can drive the gas in the cabinet to form a circulating airflow, guide the gas from the air inlet 611 into the purification box 61, and after being purified by the adsorption cotton 63 and adsorbent, it is discharged from the air outlet 612 back into the cabinet, forming a complete gas purification cycle.

[0040] As attached Figure 2 and attached Figure 5 As shown, a micro switch 7 is fixed to the inner wall of the cabinet 2 near the hinge side of the cabinet door 21 by bolts. The micro switch 7 is electrically connected to the fan 64 and the heater 65. When the cabinet door 21 is completely closed, the inner edge of the cabinet door 21 will press the trigger button of the micro switch 7, so that the micro switch 7 is in the closed state. When the cabinet door 21 is opened, the trigger button is reset by its own spring, and the micro switch 7 is in the open state. Through the linkage between the cabinet door 21 and the micro switch 7, the start and stop control of the fan 64 and the heater 65 is realized, ensuring that the purification component 6 only works when the cabinet 2 is sealed.

[0041] The implementation principle of this embodiment: When storing the circuit breaker, first unfold the folding adapter 53 and adjust the tilt angle to make it fit the ground. Then unfold the folding slide rail 51 to align it with the limiting slide rail 31 to form a continuous sliding channel. Then push the circuit breaker pulley 13 into the limiting slide rail 31 along the folding adapter 53 and the folding slide rail 51. During the process, the circuit breaker frame is guided by the arc-shaped guide part 43 of the support bracket 4 to avoid scratching. After being pushed into the preset position, the positioning pin 12 is inserted into the positioning hole 33 to achieve positioning. The support bracket 4 also shares the weight to prevent the positioning pin 12 from deforming. During storage, the cabinet door 21 presses the micro switch 7 to start the purification component 6. The fan 64 drives the air inside the cabinet to enter through the air inlet 611 of the purification box 61. First, it passes through the adsorption cotton 63 to filter solid impurities, then through the mixed adsorption on the adsorption bag rack 62 to remove moisture and corrosive components, and finally through the heater 65 to heat up and further dehumidify. The four sets of purification components 6 distributed vertically cooperate with the warm air convection to eliminate purification dead zones.

[0042] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
