Description

Technical Field

[0001] This utility model belongs to the field of drainage device technology, and in particular relates to a drainage device for cable trenches in substations. Background Technology

[0002] The drainage of water accumulated in cable trenches of substations has always been done manually. During this work, substation maintenance personnel not only have to overcome severe weather such as thunderstorms and traffic disruptions, but also have to complete a series of tasks such as pumping, wiring, and laying drainage pipes after arriving at the site. This consumes a lot of manpower and time, resulting in low efficiency of on-site emergency response. The cables being soaked in rainwater for a long time poses potential safety hazards to equipment operation, as well as personal safety hazards such as electric shock, falling objects, and traffic injuries. Therefore, a drainage device for substation cable trenches is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a drainage device for cable trenches in substations. It includes an adjustment component and a pumping component. Specifically, rotating a knob clockwise moves a support plate via a threaded rod. During this movement, a water level sensor moves along with the support plate. The position of the water level sensor can be accurately adjusted using a scale rod, thus setting its limit. When the water level reaches the set upper limit, a signal is sent through the control module to activate the water pump, which extracts the water from inside the cable trench. This solves the problem that substation cable trench drainage has traditionally relied on manual methods. Substation maintenance personnel must overcome severe weather conditions and traffic disruptions, and upon arrival at the site, they must complete a series of tasks including pump retrieval, wiring, and laying drainage pipes, consuming significant manpower and time. This results in low efficiency in on-site emergency response. Furthermore, prolonged immersion of cables in rainwater poses safety hazards, including electric shock, falling objects, and traffic injuries.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0033] Please see Figures 1-5As shown, this utility model is a substation cable trench drainage device, including a main frame mechanism 1, which includes a cable trench body 111, with a fence 112 installed inside the cable trench body 111, and a drainage section 2 installed on the left and right sides of the inner wall of the cable trench body 111. The drainage section 2 is used to pump out the water inside the cable trench body 111. A cleaning section 3 is installed on the right side of the inner wall of the cable trench body 111 and is connected to the drainage section 2. The fence 112 is used to intercept large debris in the water inside the cable trench body 111, improving the cleanliness of the inside of the cable trench body 111. The drainage section 2 includes an adjustment component 21 installed on the right side of the inner wall of the cable trench body 111 to adjust... Component 21 is used to adjust the water level limit inside the cable trench body 111. Pumping component 22 is installed on the left side of the inner wall of the cable trench body 111. Pumping component 22 works in conjunction with adjusting component 21 to automatically drain water from inside the cable trench body 111. After adjusting the water level limit inside the cable trench body 111 by adjusting component 21, when the water level reaches the upper limit, the water inside the cable trench body 111 will be drained by pumping component 22. Cleaning unit 3 includes cleaning component 31, which is installed at the bottom of adjusting component 21. Cleaning component 31 is used to clean adjusting component 21. Cleaning adjusting component 21 by cleaning component 31 improves equipment automation. To ensure operational stability, the adjustment component 21 includes a fixed plate 213 connected to the right side of the inner wall of the cable trench body 111. A control module 214 is mounted on the top of the fixed plate 213. A threaded rod 212 is threadedly connected to the back of the inside of the fixed plate 213, and a knob 211 is mounted on the top of the threaded rod 212. A scale rod 216 is welded to the front of the inside of the fixed plate 213. A support plate 217 is provided at the bottom of the fixed plate 213. The back of the inside of the support plate 217 is threadedly connected to the outer surface of the threaded rod 212, and the front of the inside of the support plate 217 is slidably connected to the outer surface of the scale rod 216. A water level sensor 215 is mounted at the bottom of the support plate 217. The bottom of the threaded rod 212 is rotatably connected to the top of the support plate 217, and the bottom of the scale rod 216 is rotatably connected to the top of the support plate 217. The bottom of the inner wall of the cable trench body 111 is connected to a water level sensor 215, whose vertical position can be adjusted by rotating a knob 211. This facilitates the adjustment of the water level limit inside the cable trench body 111. The pumping assembly 22 includes a fixed base 222, which is connected to the left side of the inner wall of the cable trench body 111. A water pump 221 is installed on the top of the fixed base 222. A drain pipe 223 is installed at the outlet of the water pump 221, and an inlet pipe 224 is installed at the inlet of the water pump 221. A filter screen 225 is installed at the inlet of the inlet pipe 224. By setting the filter screen 225, the blockage of the pipe by impurities in the water inside the cable trench body 111 is reduced. Rotating the knob 211 clockwise drives the support plate 217 to move via the threaded rod 212.During the movement of the support plate 217, the water level sensor 215 will move along with it. Simultaneously, the position and height of the water level sensor 215 can be accurately adjusted according to the scale rod 216, thereby adjusting the limit value of the water level sensor 215. When the water level reaches the set upper limit value, the control module 214 sends a signal to start the water pump 221 to extract the water from inside the cable trench body 111. By adjusting the water level limit value and automatically draining the water from inside the cable trench body 111, not only is work efficiency improved, but the workload of workers is also significantly reduced. Furthermore, by adjusting the limit value, the practicality of the equipment is greatly enhanced. The cleaning component 31 includes a protective cover 311, which is welded to the top of the support plate 217. A motor 312 is installed inside the protective cover 311. The bottom output end of the motor 312 is connected to a reciprocating screw 313 via a coupling. A cleaning brush 314 is connected to the outer surface of the reciprocating screw 313. The front side of the cleaning brush 314 connects to the outer surface of the scale rod 216, while the back side of the cleaning brush 314 contacts the outer surface of the water level sensor 215. A limit ring 315 is located at the top of the cleaning brush 314, with its inner ring connected to the outer surface of the water level sensor 215. The reciprocating motion of the cleaning brush 314 cleans the outer surface of the water level sensor 215, improving the stability of the sensor's detection. When the motor 312 is started, it drives the reciprocating screw 313 to rotate, which in turn drives the cleaning brush 314 in a reciprocating motion. This motion cleans the outer surface of the water level sensor 215, reducing the adhesion of impurities in the water and significantly improving the accuracy and stability of the device's operation.

[0034] A specific application of this embodiment is as follows: In use, the position of the water level sensor 215 is first adjusted. Specifically, the knob 211 is rotated clockwise to rotate the threaded rod 212. Since the threaded rod 212 is internally threaded with the fixed plate 213, it moves upwards when rotating. Simultaneously, the movement of the threaded rod 212 causes the support plate 217 to move upwards as well. During the upward movement of the support plate 217, it slides on the outer surface of the scale rod 216. This movement of the support plate 217 causes the water level sensor 215 to move as well. The position and height of the water level sensor 215 can be accurately adjusted according to the scale rod 216, thereby adjusting the limit value of the water level sensor 215. When the water level reaches the set upper limit value, the control module... 214 sends a signal to start the water pump 221. When the water pump 221 is working, it will draw water out of the cable trench body 111 through the water inlet pipe 224 and then discharge it through the drain pipe 223. At the same time, during the water pumping process of the water inlet pipe 224, the filter screen 225 will intercept impurities in the water, reducing the possibility of impurities in the water clogging the pipe. Meanwhile, the fixed seat 222 provides a certain support for the water pump 221 by being fixedly connected to the inner wall of the cable trench body 111. When the water level drops to the set lower limit, the water pump 221 is turned off by the control module 214. By adjusting the water level limit and automatically draining the water inside the cable trench body 111, the workload of the staff is greatly reduced. At the same time, by adjusting the limit, the practicality of the equipment is greatly improved.

[0035] Simultaneously, the motor 312 can be started by the control module 214. When the motor 312 is working, it will drive the reciprocating screw 313 to rotate. When the reciprocating screw 313 rotates, it will drive the cleaning brush 314 to move up and down. During the movement of the cleaning brush 314, its inner front surface will slide on the outer surface of the scale rod 216. At the same time, the scale rod 216 also provides a certain support for the movement trajectory of the cleaning brush 314. While the cleaning brush 314 moves up and down, it will clean the outer surface of the water level sensor 215, reducing the adhesion of impurities in the water to the outer surface of the water level sensor 215, thereby greatly improving the accuracy of the water level sensor 215 detection and greatly improving the stability of the equipment during operation. In addition, a limit ring 315 is installed on the outer surface of the water level sensor 215, which provides a certain limit to the movement range of the cleaning brush 314.
