Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical control panel drainage technology, and in particular to an electrical control panel drainage device. Background Technology
[0002] Electrical control panels are core devices for centralized control, protection, and monitoring of electrical equipment in fields such as industrial automation, power systems, rail transportation, and building electrical systems. The drainage system for electrical control panels is a water drainage and protection system specifically designed for electrical control panels (such as distribution cabinets, PLC control cabinets, and frequency converter control cabinets). Its core function is to quickly remove water accumulated inside the panel due to condensation, humid air infiltration, or external rainwater intrusion, preventing electrical components from malfunctioning due to moisture, corrosion, or short circuits. It is a crucial auxiliary device for ensuring the long-term reliable operation of the panel.
[0003] However, existing electrical control panel drainage devices do not have backflow prevention function. When there is heavy rainfall outside, rainwater can easily backflow from the drainage components into the electrical control panel, reducing the practicality of the device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a drainage device for electrical control panels.
[0005] The purpose of this utility model is achieved as follows: An electrical control panel drainage device includes: a panel body, a drainage hole at the lower end of the panel body, an anti-backflow mechanism and a guiding mechanism at the bottom of the panel body, the anti-backflow mechanism including a drainage trough, the drainage trough being assembled at the bottom of the panel body, a drainage outlet being opened inside the drainage trough, a drainage guide pipe being fixedly connected to the bottom of the drainage outlet, an external drainage pipe being assembled at the bottom end of the drainage guide pipe, a fixing plate being fixedly connected to the inner wall of the drainage guide pipe, a through groove being opened inside the fixing plate, a baffle plate being provided at the lower end of the fixing plate, the baffle plate being slidably disposed inside the drainage guide pipe, the baffle plate being able to block the through groove.
[0006] Preferably, a limiting post is fixedly connected to the upper end of the baffle, the limiting post is slidably disposed inside the fixed plate, and a limiting cap is fixedly connected to the upper end of the limiting post.
[0007] Preferably, a sliding block is fixedly connected to the side wall of the baffle, and the sliding block is slidably disposed in a slide channel opened inside the drainage guide pipe.
[0008] Preferably, the drainage guide pipe is connected to the external drainage pipe by a thread, and a sealing ring is provided at the connection between the drainage guide pipe and the external drainage pipe.
[0009] Preferably, the guiding mechanism includes a guiding inclined panel, which is disposed on the inner wall of the drainage trough. The guiding inclined panel is arranged in a stepped inclined shape, and the bottom end of the drainage trough is concave.
[0010] Preferably, the upper end of the drainage channel is fixedly connected to a mounting base, the mounting base is engaged in a mounting slot opened inside the cabinet body, the mounting base has a mounting hole opened inside the cabinet body, and a mounting bolt is installed inside the mounting hole.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model utilizes the cooperation of a drainage trough, drainage outlet, drainage guide pipe, external drainage pipe, fixed plate, through groove, baffle plate, and limiting post. Water accumulated inside the cabinet enters the drainage trough through the drainage hole, is guided by the drainage trough, and then collects at the drainage outlet. The accumulated water is discharged through the drainage guide pipe and the external drainage pipe. To prevent backflow of external rainwater, a check valve module is formed inside the drainage guide pipe. During drainage, the accumulated water, under the action of gravity and water flow impact, can push the baffle plate downwards, creating a larger space between it and the fixed plate, facilitating drainage. When water is released and discharged, and backflow occurs due to heavy external rainfall, the rainwater enters through the baffle plate. At this time, the water pressure will push the baffle plate upward, blocking the channel. The backflow of external rainwater cannot pass through the channel, thus improving the safety of the device. This allows the electrical control panel drainage device to provide backflow protection, preventing rainwater from flowing back into the electrical control panel in cases of heavy external rainfall. The baffle plate blocks the channel, preventing external rainwater from flowing back through the channel, ensuring the safety of the device and improving its practicality and safety.
[0013] 2. This utility model, through the cooperation of the guide slope panel, mounting base, mounting holes, and mounting bolts, allows water to drain from inside the control panel. The trapezoidal flow of the guide slope panel causes the water to converge at the drain outlet, increasing the drainage speed. The concave surface of the drainage trough prevents water from accumulating at the bottom. This electrical control panel drainage device enables rapid drainage, improves the drainage rate, and avoids water accumulation, thus enhancing the practicality and convenience of the device.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1-4 The present invention provides one embodiment as shown:
[0022] An electrical control panel drainage device is provided. The workbench panel 111 used in this application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies known to those skilled in the art.
[0023] Includes: a panel cabinet 111, with a drain hole at the lower end of the panel cabinet 111, and an anti-backflow mechanism 2 and a guiding mechanism 3 at the bottom of the panel cabinet 111. The anti-backflow mechanism 2 includes a drain trough 211, which is mounted at the bottom of the panel cabinet 111. A drain outlet 212 is opened inside the drain trough 211. A drain guide pipe 213 is fixedly connected to the bottom of the drain outlet 212. An external drain pipe 214 is mounted at the bottom of the drain guide pipe 213. A fixing plate 215 is fixedly connected to the inner wall of the drain guide pipe 213. A through groove 216 is opened inside the fixing plate 215. A baffle 217 is provided at the lower end of the fixing plate 215. The baffle 217 is slidably disposed inside the drain guide pipe 213 and can block the through groove 216.
[0024] When using this electrical control panel drainage device, water inside the panel 111 enters the drainage trough 211 through the drainage hole. After being guided by the drainage trough 211, the water collects at the drainage outlet 212. The water is then discharged through the drainage guide pipe 213 and the external drainage pipe 214. To prevent backflow of external rainwater, a check valve module is formed inside the drainage guide pipe 213. During drainage, the water, under the action of gravity and water flow impact, can push the baffle 217 downward, creating a larger space between it and the fixed plate 215, facilitating the release and discharge of the water. When there is heavy backflow of external rainwater, the external rainwater enters through the baffle 217. At this time, the water pressure will push the baffle 217 upward, and the baffle 217 will block the through channel 216. External rainwater cannot flow back through the through channel 216, thus improving the safety of the device.
[0025] A limit post 218 is fixedly connected to the upper end of the baffle 217. The limit post 218 is slidably disposed inside the fixed plate 215. A limit cap is fixedly connected to the upper end of the limit post 218.
[0026] The limiting cap provided at the upper end of the limiting post 218 can block the limiting post 218 and prevent the limiting post 218 from leaving the fixed plate 215.
[0027] A sliding block 219 is fixedly connected to the side wall of the baffle 217. The sliding block 219 is slidably disposed in the slide channel opened inside the drain guide pipe 213.
[0028] When the baffle 217 slides, the sliding block 219 slides synchronously in the slide channel opened inside the drain guide pipe 213, thereby limiting the baffle 217 and making its sliding more stable.
[0029] The drain guide pipe 213 is connected to the external drain pipe 214 by a thread, and a sealing ring is provided at the connection between the drain guide pipe 213 and the external drain pipe 214.
[0030] The drain guide pipe 213 is connected to the external drain pipe 214 by a thread, which facilitates disassembly and replacement. A sealing ring is provided at the connection between the drain guide pipe 213 and the external drain pipe 214, which improves the sealing performance of the connection between the drain guide pipe 213 and the external drain pipe 214.
[0031] The guiding mechanism 3 includes a guiding inclined panel 311, which is disposed on the inner wall of the drainage trough 211. The guiding inclined panel 311 is arranged in a stepped inclined shape, and the bottom end of the drainage trough 211 is concave.
[0032] When the water inside the control panel 111 is drained using this electrical control panel drainage device, it is guided by the trapezoidal flow of the inclined panel 311 to converge at the drain outlet 212, which increases the drainage speed. The floor inside the drainage trough 211 is concave, which can prevent water from accumulating at the bottom.
[0033] A mounting base 312 is fixedly connected to the upper end of the drainage trough 211. The mounting base 312 is inserted into the mounting groove opened inside the panel cabinet 111. The mounting base 312 has a mounting hole 313 inside, and the mounting hole 313 is opened inside the panel cabinet 111. A mounting bolt 314 is installed inside the mounting hole 313.
[0034] The drainage channel 211 is assembled with the cabinet body 111 using the mounting base 312 and mounting bolts 314. The operation is simple and the connection is tight, making it easy to disassemble and assemble.
[0035] Working principle:
[0036] When using this electrical control panel drainage device, water inside the panel 111 enters the drainage trough 211 through the drainage hole. After being guided by the drainage trough 211, the water collects at the drainage outlet 212. The water is then discharged through the drainage guide pipe 213 and the external drainage pipe 214. To prevent backflow of external rainwater, a check valve module is formed inside the drainage guide pipe 213. During drainage, the water, under the action of gravity and water flow impact, can push the baffle 217 downward, creating a larger space between it and the fixed plate 215, facilitating the release and discharge of the water. When there is heavy backflow of external rainwater, the external rainwater enters through the baffle 217. At this time, the water pressure will push the baffle 217 upward, and the baffle 217 will block the through channel 216. External rainwater cannot flow back through the through channel 216, thus improving the safety of the device.
[0037] When the water inside the control panel 111 is drained using this electrical control panel drainage device, it is guided by the trapezoidal flow of the inclined panel 311 to converge at the drain outlet 212, thus increasing the drainage speed. The floor inside the drainage trough 211 is concave, which can prevent water from remaining at the bottom. The operation is now complete.
[0038] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
