Description

Technical Field

[0001] This invention relates to the field of distribution cabinet technology, specifically to a power engineering distribution cabinet with protective devices. Background Technology

[0002] As an important component of the power system, the selection of the protection level of the distribution cabinet directly affects the safe operation and service life of the equipment. Different protection levels of distribution cabinets are suitable for different application scenarios to ensure the stability of the power system.

[0003] Patent CN219321841U discloses a solar power distribution cabinet with a protective mechanism, belonging to the field of power distribution cabinets. It includes a cabinet body, with an installation cabinet connected to the top of the cabinet body. A cover plate is movably connected to the top of the installation cabinet. Solar panels are installed inside the installation cabinet. The cover plate is mounted on an adjustment mechanism. Further, the adjustment mechanism includes a motor, a threaded rod, a moving block, a connecting rod, and an I-shaped block. The motor is installed on one side of the installation cabinet. The motor drives the threaded rod, which in turn drives two moving blocks away from each other. The moving blocks, via the connecting rod, support the cover plate to open. This allows the cover plate to open during the day when there is sufficient sunlight, exposing the solar panels to sunlight. When there is no sunlight, the solar panels are inside the cabinet and protected by the cover plate. This effectively prevents birds from nesting under the solar panels and prevents snow and ice from covering the solar panels in winter, thus preventing a decrease in solar energy utilization. Although this invention solves the above problems, it still has the problem of difficulty in preventing water from entering the cabinet and causing safety hazards. Therefore, a power distribution cabinet with a protective device is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent suspended conveying system for transporting wood in furniture processing, addressing the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: the elevated legs are fixedly connected to the bottom of the top frame, the hollow frame is fixedly connected to the bottom of the body, the telescopic legs also include a waterproof folding plate, one end of the waterproof folding plate is fixedly connected to the inner wall of the body, the other end of the waterproof folding plate is fixedly connected to the top of the top frame, the elevated legs are slidably connected to the inner wall of the hollow frame, the sensor and the cylinder are electrically connected, the top frame is slidably connected to the inner wall of the body, and the air inlet is located on the movement trajectory of the waterproof folding plate. When the area where the device is located experiences excessive rainfall and the road water level rises, the sensor, after sensing the rise in water level, activates the cylinder to push the top frame downward, thereby causing the elevated legs to move downward and lift the body, preventing the device from being submerged in water, which would affect the internal electrical components and cause damage to the internal components. At the same time, during the downward movement of the top frame, the waterproof folding plate unfolds and covers the inner surface of the air inlet, preventing external moisture from entering the interior of the body through the air inlet.

[0006] Preferably, the support device includes a support shell, an internal support column, a top slide groove, a side slide groove, a horizontal limiting column, a telescopic block, a return spring, and a limiting vertical groove. The support shell is fixedly connected to the left side of the machine body. The internal support column is slidably connected to the inner wall of the support shell. The top slide groove is formed at the top of the support shell. The side slide groove is formed on the side of the support shell. The horizontal limiting column is fixedly connected to the outer wall of the internal support column. The telescopic block is fixedly connected to the left side of the top frame. One end of the return spring is fixedly connected to the inner wall of the support shell. The other end of the return spring is fixedly connected to the outer surface of the internal support column. The limiting vertical groove is opened on the left side of the machine body. The support device also includes a waterproof cloth tube, a moving block, a horizontal limiting vertical groove, a waterproof cloth, a horizontal moving rod, a hollow square rod, and a square rod groove. The waterproof cloth tube is fixedly connected to the front of the machine body. The moving block is fixedly connected to the front of the elevated foot. The horizontal limiting vertical groove is opened on the front of the machine body. The waterproof cloth is slidably connected to the inner wall of the waterproof cloth tube. The horizontal moving rod is fixedly connected to the left side of the moving block. The hollow square rod is fixedly connected to the machine body. At the front, the square rod groove is opened inside the hollow square rod. The horizontal limiting post is slidably connected to the inner wall of the side sliding groove. The telescopic block is equipped with a spring and is slidably connected to the inner wall of the top sliding groove. The internal support column is located on the movement trajectory of the telescopic block and is slidably connected to the inner wall of the limiting vertical groove. The moving block is slidably connected to the inner wall of the horizontal limiting vertical groove. The horizontal moving rod is slidably connected to the inner wall of the square rod groove. The waterproof cloth is fixedly connected to the inner wall of the horizontal moving rod. When the elevated foot moves downward, it drives the top frame to move downward. At the same time, the top frame moves, driving the telescopic block to move along the trajectory of the top sliding groove, thereby driving the horizontal limiting post to move along the trajectory of the side sliding groove and driving the internal support column to move downward, which supports the device and prevents the machine from tipping over due to the high center of gravity after it rises. At the same time, during the process of the elevated foot moving downward, it drives the moving block to move downward. The downward movement of the moving block drives the horizontal moving rod to move along the trajectory of the square rod groove, thereby causing the waterproof cloth to unfold downward to seal the outer surface of the air inlet and prevent moisture from entering and damaging the electrical components inside the device.

[0007] Preferably, the drying device includes a drying box, a drive button, a spring, a push rod, an outer handle, a flexible vertical rod, a limiting horizontal post, a small limiting groove, a locking device, and an inner chamber. The drying box is fixedly connected to the inner wall of the sliding door, the inner chamber is slidably connected to the inner wall of the drying box, the outer handle is fixedly connected to the top of the inner chamber, the drive button is slidably connected to the bottom inner wall of the outer handle, one end of the spring is fixedly connected to the top of the push rod, the other end of the spring is fixedly connected to the inner wall of the outer handle, the flexible vertical rod is fixedly connected to the bottom of the push rod, the limiting horizontal post is fixedly connected to the outer wall of the flexible vertical rod, the small limiting groove is fixedly connected to the inner wall of the outer handle, the locking device is fixedly connected to the bottom of the flexible vertical rod, and the inner chamber is slidably connected to the inner wall of the drying box. The drying device also includes a torsion bar, a bidirectional screw, a gathering plate, and an inner chamber. The rod is rotatably connected to the outer surface of the inner chamber. The bidirectional screw is fixedly connected to the front of the torsion bar. The gathering plate is movably connected to the outer circumferential surface of the bidirectional screw. The locking device is slidably connected to the inner wall of the drying box. The drive button is fixedly connected to the bottom of the push rod. When the desiccant inside the device needs to be replaced, open the pull door, grasp the external handle, and press the drive button to squeeze the push rod, thereby driving the push rod to retract in the middle. This causes the elastic vertical rod to converge in the middle. Under the limitation of the limiting horizontal column and the small limiting groove, the locking device is driven to retract to both ends, so that the inner chamber and the drying box are no longer limited. At this time, lift the external handle to remove the inner chamber from the drying box for easy replacement of the desiccant. Then, rotate the torsion bar to drive the bidirectional screw to rotate and drive the gathering plate to converge in the middle, so that the desiccant inside the device gathers in the middle of the inner chamber to prevent the desiccant from adhering to the inner wall of the inner chamber and making it difficult to replace.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This power distribution cabinet with protective devices, through the cooperation of the elevated legs, the main body, the top frame, the air inlet, and the folding plate, allows the elevated legs to move downwards and lift the main body, preventing the device from being submerged in water and thus affecting the electrical components inside the device and causing damage to the internal components. During the downward movement of the top frame, the waterproof folding plate unfolds and covers the inner surface of the air inlet, preventing external moisture from entering the interior of the main body through the air inlet.

[0009] 2. The power distribution cabinet with protective device, through the cooperation of the moving block, the horizontal moving rod, the square rod groove, the air inlet, and the waterproof cloth, the moving block moves downward, driving the horizontal moving rod to move along the trajectory of the square rod groove, thereby causing the waterproof cloth to unfold downward to seal the outer surface of the air inlet and prevent moisture from entering and damaging the electrical components inside the device.

[0010] 3. The power distribution cabinet with protective device, through the cooperation of the rotating torsion bar, the double screw, the gathering plate, and the inner compartment, the rotating torsion bar drives the double screw to rotate and drive the gathering plate to gather in the middle, so that the desiccant inside the device gathers in the middle of the inner compartment, preventing the desiccant from adhering to the inner wall of the inner compartment and making it difficult to replace.

[0015] Working principle: When the area where the device is located experiences excessive rainfall and the road surface water level rises, the sensor 9, upon sensing the rise in water level, activates the cylinder 501 to push the top frame 504 downward, thereby causing the elevated legs 502 to move downward and lift the body 1. This prevents the device from being submerged in water, which could affect the internal electrical components and cause damage. At the same time, as the top frame 504 moves downward, it causes the waterproof folding plate 505 to unfold and cover the inner surface of the air inlet 6, preventing external moisture from entering the interior of the body 1 through the air inlet 6. As the elevated foot 502 moves downward, it drives the top frame 504 to move downward. Simultaneously, the top frame 504 moves, driving the telescopic block 806 to move along the trajectory of the top slide groove 803, thereby driving the horizontal limit column 805 to move downward along the trajectory of the side slide groove 804, thus supporting the device and preventing the body 1 from tipping over due to excessive center of gravity after rising. At the same time, as the elevated foot 502 moves downward, it drives the moving block 810 to move downward. The downward movement of the moving block 810 drives the horizontal moving rod 813 to move along the trajectory of the square rod groove 815, thereby causing the waterproof cloth 812 to unfold downward to seal the outer surface of the air inlet 6 and prevent moisture from entering and damaging the electrical components inside the device.
