Description

Technical Field

[0001] This invention belongs to the field of switchgear technology, specifically a water-resistant safety switchgear. Background Technology

[0002] Switchgear, as a core piece of equipment in power systems, is widely used throughout the entire process of power generation, transmission, distribution, energy conversion, and consumption. It undertakes critical responsibilities such as circuit switching, equipment control, and safety protection. Its stable operation directly affects the reliability and safety of the power system. However, in practical applications, some switchgear needs to be deployed in harsh environments such as substations in rainy areas, underground substations, and low-lying areas of industrial workshops, which are highly susceptible to the risk of rising water levels. In these scenarios, rainwater backflow, pipe leaks, or ground flooding can all lead to a continuous rise in water levels. Due to the limited sealing capabilities of existing switchgear... The existing switchgear is designed for typical humid environments and lacks specific waterproofing measures. Rising water levels can seep into the cabinet through gaps, vents, and cable interfaces. Once moisture comes into contact with precision components such as busbars, circuit breakers, and relays, it can quickly damage the insulation, causing short circuits, discharges, and other faults. This can not only burn out equipment but also lead to power outages in the area, severely impacting industrial production and residential life, and even causing safety accidents. It is evident that the shortcomings of existing switchgear in terms of waterproofing have become a prominent problem restricting the safe operation of power systems, and targeted technological upgrades are urgently needed.

[0003] For example, the invention disclosed in CN112510496A discloses a water-proof safety switch cabinet, including a support box, a cabinet body fixedly installed on the top of the support box, a frame plate slidably fitted on the support box, a grid plate fixedly installed inside the cabinet, drainage holes opened on the top of both the cabinet body and the support box, and two drainage holes on the same side are connected, a stepper motor fixedly installed on the bottom inner wall of the cabinet body, one end of a lead screw fixedly installed on the output shaft of the stepper motor, the other end of the lead screw extending into the support box, the lead screw threaded onto a lead screw seat, multiple fixing rods fixedly installed at the bottom end of the lead screw seat, and the same support plate fixedly installed at the bottom end of the multiple fixing rods, and a groove opened on one side inner wall of the drainage hole. The design is reasonable. By moving the cabinet body and frame plate upward, the height of the cabinet body can be increased. By sealing the drainage hole, water can be prevented from entering the cabinet body due to excessive water level.

[0004] In existing technologies, a screw structure is typically used to raise the height of the device to prevent liquid water from flowing back into the water due to excessive water level, thus achieving the effect of waterproofing. However, the existing structure requires a motor for control, and electric drive control does not have absolute reliability. When extreme environments cause power outages and normal power supply is not available, the waterproofing device will not be able to achieve the adjustment effect. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a water-resistant safety switch cabinet. This cabinet addresses the issues that existing structures require motor control, where electric drive control lacks absolute reliability, and where the water-resistant device cannot achieve its adjustment effect when power outages occur due to extreme environments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water-resistant safety switch cabinet, comprising a switch cabinet, wherein a linkage pressurization component is installed on one side of the switch cabinet; The linkage pressurization assembly includes a sealed cabinet door. Inside the sealed cabinet door, a compression plate is laterally movable on the side closest to the switch cabinet. Inside the sealed cabinet door, a lifting plate is slidably installed up and down on the side away from the switch cabinet. Several sets of tilting blocks are installed on one side of the compression plate and the lifting plate respectively. Three sets of fixed rods are installed at the bottom of the lifting plate. The linkage pressurization assembly includes several sets of fixed shafts. A rotating disk is welded to one end of the fixed shaft. Two sets of rotating disks are fixedly connected by rods. A drive rod is rotatably installed between the two sets of rotating disks. A top rod is rotatably installed at the upper end of the drive rod, and the top rod is located at the bottom of the fixed rod. A flipping bracket is fixedly installed on the outside of the fixed shaft. Floating columns are combined on the inner sides of the two sets of flipping brackets.

[0007] Preferably, a combination shaft is rotatably provided on the inner side of one end of the sealed cabinet door, and a cabinet door lock is embedded on the inner side of the other end of the sealed cabinet door.

[0008] Preferably, a combined bearing is fixedly installed on the outer side of the fixed shaft away from the rotating disk, two sets of limiting frames are installed at the bottom of the top rod, and the upper end of the drive rod is rotatably set inside the limiting frames.

[0009] Preferably, a fixed base is installed at the bottom of the switch cabinet near the sealed cabinet door, and the combined bearing is rotatably arranged inside the fixed base, wherein a push column is fixedly installed in the middle of the two sets of flip brackets.

[0010] Preferably, support columns are installed at the bottom of the four corners of the switch cabinet, and two sets of combined sleeves are installed on one side of the upper end of the switch cabinet, with the combined shaft rotatably arranged inside the combined sleeve.

[0011] Preferably, three sets of interlocking locking components are embedded in the bottom of the switch cabinet; The linkage locking assembly includes a combination frame, which is installed at the bottom of the switch cabinet by bolt sealing. An inclined frame is welded to the bottom of the combination frame, and two sets of limit cylinders are installed on one side of the lower end of the inclined frame. A support frame is welded to the side of the inclined frame away from the limit cylinders, and a locking post is installed on the top of the support frame at the end away from the inclined frame.

[0012] Preferably, a set of movable frames is slidably arranged on the inner side of the two sets of support frames, and the side of the movable frame close to the combined frame and the limiting cylinder are elastically connected by a tension spring. A positioning ring is installed on the end of the movable frame away from the tension spring, and the positioning ring is arranged on the outside of the locking post.

[0013] Preferably, a lower pressure plate is slidably arranged on the inner side of the movable frame, a sealing plate is installed on the top of the lower pressure plate, and the bottom of the sealing plate and the movable frame are elastically connected by several sets of support springs. A push rod is movably arranged inside the movable frame near the inclined frame, and a sealing plate is installed on the side of the push rod near the inclined frame. Three sets of limiting guide rods are installed in the middle of the sealing plate.

[0014] Preferably, three sets of limiting slide plates are slidably arranged on the outer side of the limiting guide rod, and a connecting column is installed at the bottom of the limiting slide plate. The connecting column is movably arranged on the side of the push rod away from the sealing plate.

[0015] Preferably, locking plates are installed on both sides of the connecting column, six sets of limiting frames are installed at the bottom of the inner side of the movable frame, the locking plates are movably inserted into the inner side of the limiting frames, and reinforcing corner brackets are installed on the outer side of the limiting frames.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a combination of a linkage pressurization component and a tilting bracket to lift the tilting bracket using the buoyancy of rising water levels. Adjustment of the tilting bracket further enhances sealing. As the water level rises, a float rises, and the float's thrust causes the tilting bracket to tilt along the combined bearing. Simultaneously, the rotating disk and drive rod rotate along a fixed axis, pushing the top rod upwards. As the top rod rises, it presses against three corresponding fixed rods, which in turn lift the lifting plate. The inclined surface then presses against and pushes another set of inclined surfaces and the pressing plate towards the switchgear. Since the pressing plate has a sealing structure on its side, pressure is applied to the sealing structure, ensuring it adheres tightly to the switchgear surface and further increasing sealing. Linked control of sealing adjustment via rising water levels effectively enhances the sealing effect. Furthermore, it requires no electricity, allowing adjustment even during power outages, significantly increasing the device's reliability.

[0017] This invention, through the combination of a linkage locking component and a flip bracket, facilitates the triggering of the locking device during the adjustment of the flip bracket. This locking mechanism seals the bottom heat dissipation vent, preventing water immersion and damage to the internal components. During the lifting of the flip bracket, the pushing column contacts and applies a force to the movable frame, separating the positioning ring from the locking column. After separation, the movable frame gradually tilts, and under the tension of the tension spring, it slides rapidly along the combined frame, pushing the sealing plate to impact the combined frame. During the impact, the pushing rod compresses the connecting column, causing it to move laterally. During this movement, the locking plate quickly separates from the limiting frame. After separation, under the pushing action of the support spring, the pressure plate and sealing plate quickly rise, completely sealing the opening inside the tilted frame and effectively preventing liquid from entering the heat dissipation vent.

[0020] 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.

[0021] like Figures 1 to 6 As shown, the present invention provides a water-proof safety switch cabinet, including a switch cabinet 100, and a linkage pressurization component 001 is installed on one side of the switch cabinet 100; The linkage pressurization component 001 includes a sealed cabinet door 200. Inside the sealed cabinet door 200, a compression plate 201 is laterally movable on the side near the switch cabinet 100. Inside the sealed cabinet door 200, a lifting plate 203 is slidably installed up and down on the side away from the switch cabinet 100. Several sets of tilting blocks 202 are installed on one side of the compression plate 201 and the lifting plate 203 respectively. Three sets of fixed rods 204 are installed at the bottom of the lifting plate 203. The linkage pressurization component 001 includes several sets of fixed shafts 305. A rotating disk 303 is welded to one end of the fixed shaft 305. Two sets of rotating disks 303 are fixedly connected by rods. A drive rod 304 is rotatably arranged between the two sets of rotating disks 303. A top rod 300 is rotatably arranged at the upper end of the drive rod 304, and the top rod 300 is located at the bottom of the fixed rod 204. A flipping bracket 306 is fixedly installed on the outside of the fixed shaft 305. A float 308 is combined on the inner side of the two sets of flipping brackets 306.

[0022] The above scheme employs the following: the switchgear 100 serves as the main structure of the device, enabling precise control of the power system. Sealing is achieved through the sealing door 200. The internal lifting plate 203 can move up and down along the inner side of the sealing door 200, while the pressing plate 201 can move laterally inside the sealing door 200. This movement presses against the side sealing structure within the switchgear 100, increasing the structural seal through pressure. The fixing rod 204 engages with the bottom adjustment structure, allowing for adjustment by pushing. The fixed axis 305 can restrict the outer structure. When the rotating disk 303 rotates along the fixed axis 305, the auxiliary force drives the drive rod 304 to adjust. The drive rod 304 can convert the rotational force of the rotating disk 303 into an upward thrust. Under the restriction of the limit frame 309, the top rod 300 and the drive rod 304 can be rotatably connected, ensuring that the top rod 300 can rise stably and cooperate with the fixed rod 204 to push the lifting plate 203 to move upward for adjustment. During the rising process, the flipping bracket 306 will drive the fixed axis 305 connected to it to rotate for adjustment.

[0023] like Figure 1 - Figure 5 As shown, a combination shaft 206 is rotatably provided on the inner side of one end of the sealed cabinet door 200, and a cabinet door lock 205 is embedded on the inner side of the other end of the sealed cabinet door 200.

[0024] A combined bearing 302 is fixedly installed on the outer side of the fixed shaft 305 away from the rotating disk 303. Two sets of limit frames 309 are installed at the bottom of the push rod 300. The upper end of the drive rod 304 is rotatably set inside the limit frame 309.

[0025] A fixed base 301 is installed at the bottom of the switch cabinet 100 near the sealed cabinet door 200. A combined bearing 302 is rotatably mounted inside the fixed base 301. A push column 307 is fixedly installed in the middle of the two sets of flip brackets 306.

[0026] Support columns 101 are installed at the bottom of the four corners of the switch cabinet 100. Two sets of combined sleeves 102 are installed on one side of the upper end of the switch cabinet 100. The combined shaft 206 is rotatably set inside the combined sleeve 102.

[0027] The above scheme is adopted: the combined shaft 206 can be combined and spliced ​​with the combined sleeve 102, so that the combined shaft 206 can rotate along the inner side of the combined sleeve 102, thereby opening the sealed cabinet door 200 by flipping. The cabinet door lock 205 can be used to connect the sealed cabinet door 200 to the switch cabinet 100 body to ensure that the structure can be locked. The combined bearing 302 can connect the fixed shaft 305 to the fixed seat 301, thereby ensuring that the fixed shaft 305 can be stably rotated and adjusted along the inner side. The limit frame 309 can restrict the inner structural drive rod 304. The fixed seat 301 can provide restriction for the inner structure. The push column 307 can lift the movable frame 501, which can achieve quick unlocking and assist in relocking after lifting. The support column 101 can provide support for the overall structure at the top and ensure a certain degree of stability. The combined sleeve 102 is used to splice with the combined shaft 206.

[0028] like Figures 6-9 As shown, three sets of linkage locking components 002 are embedded in the bottom of the switch cabinet 100; The linkage locking assembly 002 includes a combination frame 401, which is installed at the bottom of the switch cabinet 100 by bolt sealing. An inclined frame 402 is welded to the bottom of the combination frame 401, and two sets of limit cylinders 403 are installed on one side of the lower end of the inclined frame 402. A support frame 400 is welded to the side of the inclined frame 402 away from the limit cylinders 403, and a locking post 404 is installed on the top of the end of the support frame 400 away from the inclined frame 402.

[0029] A set of movable frames 501 is slidably arranged on the inner side of the two sets of support frames 400, and the movable frame 501 is elastically connected to the limiting cylinder 403 on the side near the combined frame 401 by a tension spring 503. A positioning ring 502 is installed on the end of the movable frame 501 away from the tension spring 503, and the positioning ring 502 is arranged on the outside of the locking post 404.

[0030] Using the above scheme: the combination frame 401 can connect the bottom inclined frame 402 to the main switch cabinet 100, and the lower end of the inclined frame 402 is an inclined opening, which can assist in air circulation and achieve heat dissipation. The limiting cylinder 403 can provide an installation position for the internal tension spring 503. The support frame 400 can restrict the sliding movable frame 501 on the inner side, which can effectively prevent it from falling off. The locking pin 404 can work with the positioning ring 502 to lock it. The movable frame 501 can provide an installation position for the internal structure. The positioning ring 502 can be locked on the outside of the locking pin 404. The tension spring 503 can provide tension to the movable frame 501. After unlocking, the tension spring 503 will quickly pull the movable frame 501 back to its original position.

[0031] like Figures 6-9As shown, a lower pressure plate 508 is slidably arranged on the inner side of the movable frame 501. A sealing plate 500 is installed on the top of the lower pressure plate 508. The bottom of the sealing plate 500 and the movable frame 501 are elastically connected by several sets of support springs 507. A push rod 504 is movably arranged inside the movable frame 501 near the inclined frame 402. A sealing plate 505 is installed on the side of the push rod 504 near the inclined frame 402. Three sets of limit guide rods 506 are installed in the middle of the sealing plate 500.

[0032] Three sets of limiting slide plates 604 are slidably arranged on the outer side of the limiting guide rod 506, and a connecting post 603 is installed at the bottom of the limiting slide plate 604. The connecting post 603 is movably arranged on the side of the push rod 504 away from the sealing plate 505.

[0033] Locking plates 600 are installed on both sides of the connecting column 603. Six sets of limiting frames 601 are installed at the bottom of the inner side of the movable frame 501. The locking plates 600 are movably inserted into the inner side of the limiting frames 601. Reinforcing corner brackets 602 are installed on the outer side of the limiting frames 601.

[0034] Using the above scheme: the lower pressure plate 508 can move up and down inside the movable frame 501. The sealing plate 500 can be used to press and seal the inner side of the inclined frame 402. The push rod 504 can be used to assist in adjusting the connecting column 603. After being pressed, the sealing plate 505 will be embedded in the inner side of the movable frame 501 to achieve a sealing effect. The limiting slide plate 604 can be used to make stable sliding adjustment along the outer side of the limiting guide rod 506. The limiting frame 601 can restrict the locking plate 600. During the movement of the connecting column 603, the locking plate 600 will move laterally and separate from the limiting frame 601. After separation, the support spring 507 will push the sealing plate 500 to rise quickly to achieve the locking and sealing effect.

[0035] The working principle and usage process of this invention: When the water level rises, the float 308 will gradually rise. During the rising process, the tilting bracket 306 will drive the rotating disk 303 to rotate and adjust along the fixed shaft 305. During adjustment, the drive rod 304 will push the limit frame 309 and the top rod 300 to rise. During the rising process, the top rod 300 will push the fixed rod 204 and the lifting plate 203 to rise along the sealing cabinet door 200. During the rising process, the tilting block 202 pushes the squeezing plate 201 and the sealing structure to move laterally to achieve the squeezing and sealing effect. During the lifting process, the tilting bracket 306... The push column 307 will push the movable frame 501 to rise. When it rises, the positioning ring 502 will separate from the locking column 404. After separation, the tension spring 503 will quickly pull the movable frame 501 into the inner side of the inclined frame 402 to slide. When sliding, it will hit the sealing plate 505 and the push rod 504 to enter the interior of the movable frame 501. The push rod 504 will squeeze the connecting column 603 to move laterally. When moving, the locking plate 600 will quickly separate from the limiting frame 601. After separation, the support spring 507 will push the lower pressure plate 508 and the sealing plate 500 to rise quickly and squeeze the inclined frame 402 to achieve a sealing effect.
