The overflow tank 131 is used for preliminary sedimentation of sand and gravel, the sedimentation tank 132 is used for secondary sedimentation of sand and gravel, and the water collection tank 133 is used to collect the supernatant.
[0031] By setting up an overflow trough 131, a sedimentation trough 132, and a water collection trough 133, the flushed water is subjected to graded sedimentation treatment. The collected supernatant is reused for flushing operations through a flushing pump 112 and a water delivery pipe 121, which greatly improves the utilization efficiency of water resources and reduces water waste and treatment costs. The clamping block 211 and the limiting pulley 212 set on the outside of the flushing head 21 enable the flushing head 21 to move stably when operating in the oil well, avoiding shaking and ensuring the sand flushing effect. At the same time, the setting of the guide component 215 optimizes the flushing water flow and further improves the sand flushing efficiency.
[0032] Furthermore, a water pump 111 and a flushing pump 112 are installed inside the power box 11. Two sets of water pipes 121 are provided. One set passes through the power box 11 and is connected to the water pump 111 and inserted into the inside of the overflow tank 131. The other set of water pipes 121 passes through the power box 11 and is connected to the flushing pump 112 and inserted into the inside of the water collection tank 133. This is used to extract the supernatant collected in the water collection tank 133 for flushing operations.
[0033] Furthermore, the water collection tank 133 is located directly below the overflow tank 131, and the sedimentation tank 132 is sleeved on the outside of the overflow tank 131 and the water collection tank 133. The water collection tank 133 is provided with a connecting port that connects to the overflow tank 131.
[0034] Specifically disclosed, the working unit 2 includes a flushing head 21 and a connector 22. A collar 221 is provided on the inner side of the connector 22. The connector 22 is inserted into the inner side of the connector 12. The collar 221 is sleeved on the outer side of the water supply pipe 121.
