technical field

The utility model relates to a drainage device, in particular to a device for pumping and draining accumulated water in a power cable ditch.

Background technique

At present, in the rainy summer season, due to the large amount of rainwater entering the power cable trench, it is easy to cause a short circuit fault and cause a large-scale power outage. When it is found that rainwater is accumulated in a certain cable trench, the pump is immediately discharged to pump water to prevent the accumulation of rainwater from causing short-circuit accidents; Factors cause a large amount of rainwater to accumulate in a short period of time, which is still easy to cause short-circuit accidents, thereby affecting the power supply guarantee of the corresponding area.

detailed description

Referring to Fig. 1, the utility model is an automatic drainage device for electric cable ditch, the device includes a water suction pipe installed in the cable ditch, the water suction pipe is connected with the water pump, and the open end of the water suction pipe is inserted into the cable At the bottom of the ditch, a detection device for detecting the water level is provided on the side wall of the cable ditch. The detection device is connected to the controller, and the controller is connected to the contactor. The control part of the contactor is connected in series to the water pump. on the power supply circuit;

Preferably, the detection device is provided with two upper and lower detection devices, the detection device at the upper part is used to detect high water level, and the detection device at the lower part is used to detect low water level; further, the detection device is a probe or a water level sensor;

Further, the power supply of the pump is a battery, and the battery is connected to a solar panel through a battery charge and discharge management module, and the solar panel is laid on the top cover of the cable trench; Charging, using the battery to discharge;

Preferably, the power supply circuit of the water pump is a dual-circuit power supply mode formed by parallel connection of commercial power and batteries, so as to ensure the supply of power and the reliability of drainage.

The steps of using an automatic drainage device for electric cable trenches involved in the utility model are as follows:

Step 1. Arrange the suction pipe in the cable trench, connect the suction pipe to the pump, and insert the open end of the suction pipe into the bottom of the cable trench to drain the accumulated water in the cable trench;

Step 2, the side wall in the cable trench is provided with a detection device for detecting the water level;

Step 3, the signal detected by the detection device is sent to the controller, and the controller sends the control signal to the contactor, and the control part of the contactor is connected in series with the power supply circuit of the pump;

Step 4. When the detection device detects that the water level in the cable trench is higher than the set high water level, the controller starts the water pump through the contactor, thereby pumping the accumulated water in the cable trench to the outside of the trench;

Step 5. When the water pump continues to pump water and the detection device detects that the accumulated water level drops to a predetermined low water level, the controller stops the water pump through the contactor, so as to avoid heat damage caused by the water pump working for a long time;

In addition: it should be noted that the above specific implementation is only an optimization solution of this patent, and any changes or improvements made by those skilled in the art based on the above ideas are within the scope of protection of this patent.
