Problems solved by technology

[0003] At present, whether it is sand pumping or sand discharge, manual backfilling is used, which is time-consuming and laborious, and has potential safety hazards. Due to the small space inside the cable trench, the efficiency of manual sand pumping and sand discharge is low; in addition, between two adjacent working wells The distance between the two working wells is far away, which makes it difficult to manually complete the work of sand pumping and sand discharge in the cable trench section between the two working wells, which further reduces the work efficiency. sand automation

Abstract

The embodiment of the invention discloses an automatic device suitable for sand pumping and discharging of a cable working well. The automatic device comprises a frame body, and a negative pressure sand pumping mechanism, a sand bin, a positive pressure sand discharging mechanism, a fan set and a hydraulic valve set used for controlling the negative pressure sand pumping mechanism and the positivepressure sand discharging mechanism arranged on the frame body, wherein the fan set is connected with an air compressor, the fan set comprises a first fan used for providing sand pumping power and asecond fan used for providing sand discharging power, the first fan is connected with the negative pressure sand pumping mechanism, the second fan is connected with the positive pressure sand discharging mechanism, the negative pressure sand pumping mechanism is connected with the sand bin, and the sand bin is connected with the positive pressure sand discharging mechanism. The device has the functions of sand pumping and sand discharging at the same time, operation is easy and convenient, and the working efficiency is greatly improved.

Description

technical field [0001] The present application relates to the technical field of sand pumping and discharging equipment, in particular to an automatic device for pumping and discharging sand in cable wells. Background technique [0002] The cable trench of the substation is an underground special channel for laying power cables, which plays a very important role in the normal operation of the cables. Transmission cables are generally laid in cable trenches. After the transmission cables are laid in the cable trenches, it is often necessary to discharge sand into the cable trenches to completely cover the transmission cables, so as to achieve the effect of fire prevention and anti-theft; when the transmission cables fail , It is also necessary to extract the sand before the fault maintenance of the transmission cable can be carried out. [0003] At present, whether it is sand pumping or sand discharge, manual backfilling is used, which is time-consuming and laborious, and ha...
