Embodiment 1

[0075] Such as figure 1 As shown, a substation intelligent drainage system is composed of a pumping device 3, a water level monitoring device 12, a silt detection device 5, a rainfall monitoring device 6, and a controller 1, the pumping device 3, a water level monitoring device 12, a silt detection device 5, and a rainfall monitoring device The devices 6 are electrically connected to the controller 1 respectively. The controller 1 is composed of a main control chip 11, a power supply 12, a communication module 13, an alarm device 15, a locator 17 and a switch device 16. The power supply 12 is electrically connected to the controller 1. The main control The chip 11 is electrically connected to the alarm device 15 , the communication module 13 , the locator 17 and the switch device 16 respectively.

[0076]In the present embodiment, communication module 13 adopts GTM900-C GPRS communication module 13, the stability of data transmission based on GTM900-C GPRS communication module...

Embodiment 2

[0093] Embodiment 2 is the improvement to water pump on the basis of embodiment 1, as Figure 8 Shown is the installation structure diagram of the water pump, and the water pump of embodiment 2 is installed at the bottom of the sump well.

[0094] Such as Figure 9 , Figure 10 As shown, the water pump 321 includes a support ring 503-water outlet 504-motor 501 and water pump blades 505. The lower part of the support ring 503 is in the shape of an inverted bell mouth. The lower part of the support ring 503 has a strip-shaped water inlet gap along the circumference. It is a collection part 502 in a cylindrical tubular shape. The water outlet 504 is installed in the middle of the support ring 503 and communicates with the collection part 502. The motor 501 is fixedly installed on the top of the support ring 503. The top of the support ring 503 has an end cover. The output shaft of the motor 501 extends into The lower part of the support ring 503, the water pump blade 505 is fix...

Embodiment 3

[0100] This embodiment has been further improved on the basis of Embodiment 1, such as Figure 13 As shown, the water belt 511 in this embodiment also includes a water inlet head 512, the water belt 511 is a hollow cuboid, the free end of the water belt 511 is closed, and there are several gaps on both sides of the water belt 511. The water head 512; the water inlet head 512 includes a shell and a floating block 5122, the two ends of the shell are open, one end of the shell is connected to the gap, and the other end of the shell is processed with a slot 5121 for clamping the floating block 5122 along the plumb direction , the floating block 5122 is movably engaged in the slot 5121 along the vertical direction, and the floating block 5122 covers the opening area. When there is accumulated water at the water inlet head 512, the accumulated water has a buoyancy effect on the floating block 5122, thereby opening the water inlet head 512, so that the water body can enter the hose 5...

Abstract

The invention discloses an intelligent drainage system and method for a transformer substation. The system comprises a water pumping device, a water level monitoring device, a sludge detection device,a rainfall monitoring device and a controller which are installed in a cable trench. The water pumping device is used for pumping accumulated water in the cable trench and is electrically connected with the controller; the water level monitoring device is used for monitoring the water accumulation condition in the cable trench and is electrically connected with the controller; the controller is used for processing feedback information of the water level detection device and controlling starting and stopping of the water pumping device and is in communication connection with the remote terminal; the rainfall monitoring device is used for monitoring environment rainfall and is electrically connected with the controller; and the sludge detection device is used for monitoring the sludge deposition condition at the bottom of the cable trench and is electrically connected with the controller. According to the device, the sludge deposition condition in the cable trench is considered; the vibration device, the transmission device and the stirring device are arranged, so the measurement accuracy of the water level gauge and the water pumping efficiency of the water pumping device are guaranteed.

Description

technical field [0001] The invention relates to the technical field of power equipment protection, in particular to a substation intelligent drainage system and a method thereof. Background technique [0002] Cable trench is an underground pipeline used to place and protect cable facilities, and is an indispensable infrastructure in power plants-substations-municipal engineering and large factories and mines. However, due to terrain or design factors, it is easy to accumulate water in the cable trench during heavy rain or rainy season. If the water level is too high, the cables in the cable trench will be soaked in water for a long time and corroded, which will not only damage the insulation of the cable, but also affect its In severe cases, it will also cause bursting due to water ingress in the cable. [0003] The drainage speed of the existing cable trench drainage system is slow. After the rain, staff need to go to the site to inspect and realize manual drainage, which ...
