Description

Technical Field

[0001] This utility model relates to the field of snake-skin pipe drainage technology, and in particular to a device for automatic drainage of snake-skin pipes. Background Technology

[0002] Cable conduits are widely used in electrical circuit protection, effectively preventing wire wear and compression. They also possess good flexibility, corrosion resistance, high-temperature resistance, wear resistance, and tensile strength. In practical applications, cable conduits are typically used at the connection points between cable trays and control cabinets, or between cable trays and equipment, or between control cabinets and equipment. During rainy weather, exposed equipment or semi-enclosed factory buildings are frequently exposed to rainwater, which can flow into the conduits and then into the equipment, causing a decrease in insulation, leading to short circuits, tripping, explosions, or equipment burnout. This threatens personal safety and disrupts safe production operations. Some equipment uses a bottom-entry wiring method to connect to the control cabinet or junction box, reserving a portion of the cable in a U-shaped route to prevent direct rainwater flow. However, in heavy rain or storms, the U-shaped area is highly likely to fill with water, still failing to effectively prevent rainwater from entering the equipment through the conduit. The current solution is to create a drainage hole at the lowest point of the U-shaped section to allow accumulated rainwater to drain smoothly. However, the existence of this hole may also bring new hidden dangers: small animals may enter the equipment's junction box through the hole, causing a short circuit and ultimately leading to the equipment tripping due to a grounding fault.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-7 As shown, this utility model provides a first embodiment of a device for automatic drainage of a snake-skin hose, including a water storage pipe 1 connected to the bottom of the U-shaped section of the snake-skin hose 100, allowing rainwater in the snake-skin hose 100 to flow into the water storage pipe 1. A movable baffle 2 is provided at the lower opening of the water storage pipe 1, and the movable baffle 2 is reset by a counterweight 3. When the weight of the water in the water storage pipe 1 is greater than the weight of the counterweight 3, the water presses down on the movable baffle 2, causing the lower opening of the water storage pipe 1 to open for drainage. After drainage is completed, the movable baffle 2 is reset by the gravity of the counterweight 3 to seal the lower opening of the water storage pipe 1, preventing small animals from entering.

[0019] The movable baffle 2 includes a circular baffle 21 for blocking the lower opening of the water storage pipe 1. A connecting rod 22 is fixed to the right end of the circular baffle 21, and a counterweight 3 is fixed to the right end of the connecting rod 22. An upper connecting rod 23 is fixed to the connecting rod 22 to the left of the counterweight 3, and the upper end of the upper connecting rod 23 is hinged to the outer right wall of the water storage pipe 1. When the weight of the water in the water storage pipe 1 is greater than the weight of the counterweight 3, the water presses down on the circular baffle 21, causing the circular baffle 21 to rotate downward around the hinge point between the bend and the mounting hole, thus opening the lower opening of the water storage pipe 1 for drainage. After drainage is completed, the weight of the counterweight 3 causes the circular baffle 21 to rotate upward around the hinge point between the bend and the mounting hole to reset, thereby sealing the lower opening of the water storage pipe 1 and preventing small animals from entering.

[0020] Based on the first embodiment, this utility model provides a second embodiment of a device for automatic drainage of snake skin pipes, wherein the counterweight 3 can be a square, but is not limited to this.

[0021] Based on any of the above embodiments, the present invention provides a third embodiment of a device for automatic drainage of snake skin pipes, wherein the counterweight 3 is connected to the connecting rod 22 by a first bolt (not shown), which facilitates disassembly and assembly.

[0022] Based on any of the above embodiments, this utility model provides a fourth embodiment of a device for automatic drainage of snake-skin pipes, wherein the center of the circular baffle 21 is vertically aligned with the center of the lower opening of the water storage pipe 1, and the radius of the circular baffle 21 is 1 mm larger than the radius of the lower opening of the water storage pipe 1, ensuring that the circular baffle 21 can completely cover the lower opening of the water storage pipe 1, preventing small animals from entering the equipment along the lower opening of the water storage pipe 1 and affecting the equipment.

[0023] Based on any of the above embodiments, the present invention provides a fifth embodiment of a device for automatic drainage of a snake-skin pipe, wherein the upper opening of the water storage pipe 1 has a left extension plate 4 and a right extension plate 5, and the bottom of the U-shaped position of the snake-skin pipe 100 is provided with a connection port 200 that communicates with the upper opening of the water storage pipe 1.

[0024] The length of the right extension plate 5 is one-third the length of the left extension plate 4, which facilitates installation and increases stability.

[0025] The upper end of the outer wall of the water storage pipe 1 has an external thread 6, which is engaged with the internal thread of a fixing ring 7. The fixing ring 7 can further limit the water storage pipe 1 and prevent it from moving.

[0026] In this embodiment, the radius of the connection port 200 is larger than the radius of the pipe opening on the water storage pipe 1, so that the left extension plate 4 and the right extension plate 5 can extend into the snake-skin pipe 100 from the connection port 200. The outer radius of the fixing ring 7 is larger than the radius of the connection port 200, which can cover the uncovered part 300 of the connection port 200.

[0027] During installation, after inserting the left extension plate 4 into the flexible hose 100 through the connection port 200, move the water storage pipe 1 to the left so that the right extension plate 5 is located inside the connection port 200. Then, insert the right extension plate 5 into the flexible hose 100 through the connection port 200. Next, move the water storage pipe 1 to the right to align with the center of the connection port 200. At this point, the bottom of both the left extension plate 4 and the right extension plate 5 are stuck on the inner wall of the flexible hose 100. Finally, rotate the fixing ring 7 so that it moves upward until it touches the flexible hose 100. Since the outer radius of the fixing ring 7 is larger than the radius of the connection port 200, the circular part 71 of the fixing ring 7 can cover the uncovered part 300 of the connection port 200, thus completing the installation of the water storage pipe 1.

[0028] Based on the fifth embodiment, this utility model provides a sixth embodiment of a device for automatic drainage of snake-skin pipes. The right extension plate 5 and the left extension plate 4 are both connected to the U-shaped position of the snake-skin pipe 100 by the second bolt 8. The water storage pipe 1 can be further fixed to the snake-skin pipe 100 by the second bolt 8.

[0029] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
