Description

Technical Field

[0001] This invention relates to the field of intelligent switchgear technology, specifically a protective outdoor intelligent switchgear. Background Technology

[0002] Intelligent switchgear is a type of electrical equipment. External power lines first enter the main control switch inside the cabinet, then the branch control switches. Each branch circuit is configured according to its needs, such as instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage distribution cabinets, and high-voltage busbars, such as in power plants. Some also have underfrequency load shearing features to protect key equipment. Switchgear, distribution cabinets, and other electrical cabinets placed outdoors inevitably face the challenges of rain, wind, sand, and dust entering the cabinet.

[0003] The prior art, CN 118539318 B, describes a protective outdoor intelligent switchgear, including a switchgear body, a water collection shed, and heat dissipation holes. The switchgear body contains gears, and a first rack meshing with the gears is inserted into the side wall of the switchgear body. A water collection tank is installed outside the first rack and located outside the switchgear body. A second rack meshing with the gears is located inside the switchgear body, and a vent plate is located at the end of the second rack. A water baffle is connected to the lower end of the vent plate. A drying device for drying the vent plate is installed inside the switchgear body. Rainwater is blocked and absorbed by the vent plate. When the water collection shed is full, it begins to drain water. The descending water collection shed causes the water baffle to rise and close the heat dissipation holes. The drying device dries the damp vent plate. When the rainwater in the water collection shed is drained, the vent plate moves down to cover the heat dissipation holes, minimizing the possibility of rainwater entering the switchgear body through the holes, thereby improving the waterproof performance of the switchgear body.

[0004] However, the aforementioned covering structure for the heat dissipation holes mainly relies on the gravity of collected rainwater as its power source, which cannot prevent wind-blown dust and other impurities from entering the cabinet. This can cause short circuits due to the dust and other impurities adhering to the circuitry. Furthermore, in reality, the top edge of the heat dissipation holes on the cabinet is typically formed by a single stamping process, which can block rainwater from entering the cabinet to the greatest extent. Therefore, a protective outdoor intelligent switch cabinet is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a protective outdoor intelligent switch cabinet in order to solve the above-mentioned problems.

[0006] The present invention achieves the above objectives through the following technical solution: a protective outdoor intelligent switch cabinet, comprising a cabinet body, a durable sheet, a shielding sheet, a strip plate, an electromagnet, and a touch delay switch. A water pipe is connected to one side of the water collection tank at the top of the cabinet body, and one end of the water pipe is inclined downward toward an E-shaped hole located on one side of the cabinet body. The inner edge of the E-shaped hole is sealed and fixedly connected to the outer edge of the corrugated edge on the durable sheet body. Multiple connecting holes are arranged in a row on the side wall of the top of the shielding plate, and a ball is rolled in each connecting hole. A short protrusion on each ball is fixedly connected to the corresponding part on the back of the durable sheet. A touch element is installed on the bottom side wall of the strip plate located at the corner of the middle of the shielding plate, and the touch element and the sensing part located on the touch delay switch make contact with each other through movement. The electromagnet is installed on the side wall at the bottom of the shielding plate, and the electromagnet is electrically connected to the touch delay switch through a wire. The electromagnet is magnetically attracted to the corresponding metal wall inside the heat dissipation hole through a magnetic field.

[0007] Preferably, the heat dissipation holes are provided in multiple ways, and the multiple heat dissipation holes are distributed in a matrix on the corresponding parts of the cabinet surface, and each heat dissipation hole is provided with a rainproof protrusion at the top of the opening.

[0008] Preferably, a gap is left between the heat dissipation hole and the side wall at the bottom of the shielding plate.

[0009] Preferably, a rotating shaft is installed on both sides of the middle part of the shielding plate, and the outer end of the rotating shaft is fixedly connected to the corresponding part of the inner wall of the cabinet through a side support plate, and a torsion spring is fitted on the rotating shaft.

[0010] Preferably, the water collection tank opening is fixedly connected to the external filter screen structure.

[0011] Preferably, the corrugated edge portion forms a telescopic structure through cross-sectional corrugations.

[0012] Preferably, the lowest edge inside the E-shaped hole is flush with the lowest edge of the durable sheet.

[0013] The beneficial effects of this invention are: 1. The rainwater from the height difference flows out from the inclined downward port of the water pipe, forming an impact thrust on the durable sheet located at the E-type hole, or the external wind force passes through the E-type hole to form an impact thrust on the durable sheet. This is conducive to the side rotation of the shielding plate connected to the durable sheet, and further provides emergency shielding for the heat dissipation holes, preventing dust or rainwater from entering the power distribution cabinet. The shielding protection is effective and quick. 2. By using the moving strip plate, the bottom of the touch component connected to it is brought close to the sensing part on the touch delay switch, so as to trigger the touch delay switch to be powered on. This helps to magnetically cover and fix the lower half of the thin plate at the heat dissipation hole, and by using the delayed power-off property of the touch delay switch, the magnetic field on the electromagnet is released, avoiding long-term covering of the heat dissipation hole and ensuring the heat dissipation effect of the equipment inside the cabinet. Third, by using an electromagnet, the touch delay switch can be switched between having a magnetic field and not having a magnetic field during its on / off interval. This allows the connected shielding plate to cover the heat dissipation holes in a windless environment, increasing the diversity of ways to cover the heat dissipation holes and making it highly applicable.

[0020] Please see Figure 1-5 As shown, a protective outdoor intelligent switch cabinet includes a cabinet body 1, a durable sheet 3, a shielding sheet 5, a strip plate 6, an electromagnet 7, and a touch delay switch 8. A water pipe 2 is connected to one side of the water collection tank 130 at the top of the cabinet body 1, and one end of the water pipe 2 is inclined downward toward the E-shaped hole 120 located on one side of the cabinet body 1. The inner edge of the E-shaped hole 120 is sealed and fixedly connected to the outer edge of the corrugated edge portion 310 on the durable sheet 3. Rainwater is collected and gathered by the water collection trough 130, and combined with the water pipe 2 connected to the water collection trough 130, the rainwater can flow out from the inclined downward port of the water pipe 2 under the action of height difference, forming an impact thrust on the durable sheet 3 located at the E-type hole 120.

[0021] The top side wall of the shielding plate 5 has multiple connecting holes 510 arranged in a row, and each connecting hole 510 is connected with a ball 4 in a rolling manner. The short protrusion 410 on each ball 4 is fixedly connected to the corresponding part on the back of the durable sheet 3. When rainwater flowing from the inclined downward port of the water pipe 2 impacts the durable sheet 3, or when wind impacts the durable sheet 3 in non-rainy weather, the durable sheet 3 bulges inward and moves backward under the impact thrust, thereby pushing the top of the shielding plate 5, which is connected by the short protrusion 410, the ball 4, and the connecting hole 510, backward. According to the lever principle, the bottom end of the shielding plate 5 moves forward, so that the lower half of the shielding plate 5 covers the heat dissipation hole 110, thus playing the role of emergency covering of the heat dissipation hole 110.

[0022] A touch element 820 is installed on the bottom side wall of the strip plate 6 located at the middle corner of the shielding plate 5, and the touch element 820 and the sensing part 810 located on the touch delay switch 8 are in contact with each other through movement. The electromagnet 7 is installed on the bottom side wall of the shielding plate 5, and the electromagnet 7 is electrically connected to the touch delay switch 8 through a wire. The electromagnet 7 is magnetically attracted to the corresponding metal wall inside the heat dissipation hole 110 through a magnetic field. Under the side-turning action of the shielding plate 5, the strip plate 6 connected to the middle corner of the shielding plate 5 moves forward until the touch element 820 at the bottom of the strip plate 6 comes into close contact with the sensing part 810 located on the touch delay switch 8, thereby triggering the touch delay switch 8 to be energized. This causes the electromagnet 7 to be energized and magnetically attracted and fixed to the metal surface around the heat dissipation hole 110. After the touch delay switch 8 is triggered and delayed for a set time interval, it is de-energized, releasing the magnetic field on the electromagnet 7 and avoiding long-term covering of the heat dissipation hole 110, thus ensuring the heat dissipation effect of the equipment inside the cabinet 1.

[0023] The heat dissipation holes 110 are provided in multiple ways, and the multiple heat dissipation holes 110 are distributed in a matrix on the corresponding parts of the surface of the cabinet 1. Each heat dissipation hole 110 is provided with a rainproof protrusion at the top of the opening. The rainproof protrusion can block rainwater from entering the cabinet 1 through the heat dissipation hole 110 to the greatest extent.

[0024] A gap is left between the heat dissipation hole 110 and the side wall at the bottom of the shielding plate 5 so that the lower half of the shielding plate 5 can move to perform shielding and repositioning.

[0025] The shielding plate 5 has a rotating shaft installed on both sides of the middle section, and the outer end of the rotating shaft is fixedly connected to the corresponding part of the inner wall of the cabinet 1 through the side support plate 9. A torsion spring is installed on the rotating shaft. By setting the torsion spring, combined with the impact force on the durable sheet 3 and the electromagnet 7 to release the magnetic field, the shielding plate 5 is guaranteed to be reset.

[0026] The opening of the water collection tank 130 is fixedly connected to the external filter screen structure. The external filter screen structure prevents impurities from accumulating in the water collection tank 130 and clogging the water guide pipe 2.

[0027] The corrugated edge portion 310 forms a telescopic structure through the corrugated cross section, which causes an inward displacement of the durable sheet 3.

[0028] The lowest edge inside the E-shaped hole 120 is flush with the lowest edge of the durable sheet 3, so that impurities slide to the outside during the reset movement of the durable sheet 3, thus avoiding impurity accumulation.

[0029] Working principle: Rainwater is collected and gathered together by the water collection tank 130, and combined with the water guide pipe 2 connected to the water collection tank 130, the rainwater can flow out from the inclined downward port of the water guide pipe 2 under the action of height difference, forming an impact thrust on the durable sheet 3 located at the E-type hole 120. When rainwater flowing from the inclined downward port of the water pipe 2 impacts the durable sheet 3, or when wind impacts the durable sheet 3 in non-rainy weather, the durable sheet 3 bulges inward and moves backward under the impact thrust, thereby pushing the top of the shielding plate 5, which is connected by the short protrusion 410, the ball 4, and the connecting hole 510, backward. According to the lever principle, the bottom of the shielding plate 5 moves forward, so that the lower half of the shielding plate 5 covers the heat dissipation hole 110, thus playing the role of emergency covering of the heat dissipation hole 110. Under the side-turning action of the shielding plate 5, the strip plate 6 connected to the middle corner of the shielding plate 5 moves forward until the touch element 820 at the bottom of the strip plate 6 comes into close contact with the sensing part 810 located on the touch delay switch 8, thereby triggering the touch delay switch 8 to be energized. This causes the electromagnet 7 to be energized and magnetically attracted and fixed to the metal surface around the heat dissipation hole 110. After the touch delay switch 8 is triggered and delayed for a set time interval, it is de-energized, releasing the magnetic field on the electromagnet 7 and avoiding long-term covering of the heat dissipation hole 110, thus ensuring the heat dissipation effect of the equipment inside the cabinet 1.

[0030] The supplementary information includes: Combination Figure 1 It can be seen that the length of water pipe 2 is greater than half the height of cabinet 1, which can create a sufficient height difference. Secondly, Figure 1 The bottom port of the central water pipe 2 is inclined towards the durable sheet 3. The technical feature of this part is that "one end of the water pipe 2 is inclined downwards towards the E-shaped hole 120 located on one side of the cabinet 1," thus quickly redirecting vertically falling rainwater to impact the durable sheet 3. The redirected rainwater, with kinetic energy, continuously strikes the drum surface. "When rainwater flowing from the inclined downward port of the water pipe 2 impacts the durable sheet 3, or when it impacts the durable sheet 3 under wind force in non-rainy weather, the durable sheet 3 bulges inwards and moves backwards under the impact thrust." To ensure that the "durable sheet 3" has a certain amount of expansion and contraction (the durable sheet 3 bulges inwards and moves backwards), "the corrugated edge portion 310 is specially designed at the edge of the durable sheet 3 to form an expansion and contraction structure through cross-sectional corrugations, creating an inward displacement of the durable sheet 3," thus ensuring sufficient thrust to push the durable sheet 3. Combination Figure 3As shown, one end of the strip plate 6 is connected to the corner of the middle of the shielding plate 5, and the connection relationship between the corner of the middle of the shielding plate 5 and the two side support plates 9 is: "Both sides of the middle of the shielding plate 5 are equipped with rotating shafts, and the outer ends of the rotating shafts are fixedly connected to the corresponding parts of the inner wall of the cabinet 1 through the side support plates 9". It can be seen that the corner of the middle of the shielding plate 5 is the rotating shaft part. Therefore, when the corner of the middle of the shielding plate 5 rotates to the side, the corner of the middle of the shielding plate 5 drives the strip plate 6 to rotate to the side. The "strip plate 6" can be made of lightweight material. At the same time, the bottom end of the strip plate 6, which is equipped with the "touch element 820", moves backward relative to the top end of the shielding plate 5 and forward, and is in a forward-moving state. The operating principle is: "Under the impact thrust, the durable sheet 3 bulges inward and moves backward, so as to achieve the connection of the short protrusion 410, the ball 4, and the connecting hole 510." The top of the shielding plate 5 is pushed backward, and according to the lever principle, the bottom of the shielding plate 5 is pushed forward, so that the lower half of the shielding plate 5 covers the heat dissipation hole 110, which serves as an emergency cover for the heat dissipation hole 110; under the side rotation of the shielding plate 5, the strip plate 6 connected to the middle corner of the shielding plate 5 moves forward until the touch element 820 at the bottom of the strip plate 6 comes into close contact with the sensing part 810 located on the touch delay switch 8, thereby triggering the touch delay switch 8 to be energized, so that the electromagnet 7 is energized and magnetically attracted and fixed to the metal surface around the heat dissipation hole 110, and the touch delay switch 8 is de-energized after a set time interval, releasing the magnetic field on the electromagnet 7, avoiding long-term covering of the heat dissipation hole 110, and ensuring the heat dissipation effect of the equipment inside the cabinet 1; "The strip plate 6, connected to the corner of the shielding plate 5, moves forward until the touch element 820 at the bottom of the strip plate 6 comes into close contact with the sensing part 810 located on the touch delay switch 8, thereby triggering the touch delay switch 8 to be energized. This causes the electromagnet 7 to be energized and magnetically attracted and fixed to the metal surface around the heat dissipation hole 110. After the touch delay switch 8 is triggered, it is de-energized after a set time interval, releasing the magnetic field on the electromagnet 7 and preventing prolonged coverage of the heat dissipation hole 110, thus ensuring the heat dissipation effect of the equipment inside the cabinet 1." The main objective is... The result is that in rainy weather, under the action of wind or rain impact on the durable thin sheet 3, and the wind and rain impact force is not uniform, the shielding sheet 5 is in a state of back-and-forth swinging and side-turning in windy and rainy weather. Since the heat dissipation hole 110 inside the cabinet 1 cannot be closed for a long time, the electromagnet 7 is energized to generate magnetic attraction and fix it to the metal surface around the heat dissipation hole 110. Combined with the trigger touch delay switch 8, the heat dissipation hole 110 can be opened and closed quickly for 10 minutes. The "trigger touch delay switch 8 delay to the set time" can be achieved at any time required by existing technology.

[0031] In summary, compared with the existing technology, the difference lies in the fact that the rainwater from the height difference flows out from the inclined downward port of the water pipe 2 to form an impact thrust on the durable sheet 3 located at the E-type hole 120, or the external wind force passes through the E-type hole 120 to form an impact thrust on the durable sheet 3. This is conducive to the side rotation of the shielding plate 5 connected to the durable sheet 3, and further provides emergency shielding for the heat dissipation hole 110, preventing dust or rainwater from entering the power distribution cabinet. Moreover, the shielding protection is effective and quick. The touch element 820 connected to the bottom of the moving strip plate 6 is brought close to the sensing part 810 located on the touch delay switch 8, so as to trigger the touch delay switch 8 to be powered on. This helps to magnetically cover and fix the lower half of the shielding plate 5 at the heat dissipation hole 110. With the help of the delayed power-off property of the touch delay switch 8, the magnetic field on the electromagnet 7 is released, avoiding long-term covering of the heat dissipation hole 110 and ensuring the heat dissipation effect of the equipment inside the cabinet 1. The electromagnet 7 can also be used to switch between having a magnetic field and not having a magnetic field by using the touch delay switch 8 to switch between being powered on and off. This achieves the effect of covering the heat dissipation hole 110 with the connected shielding plate 5 in a windless environment, increasing the diversity of ways to cover the heat dissipation hole 110 and making it highly applicable.
