Embodiment Construction
[0020] Such as Figure 1-3 As shown, an electronically controlled pumping and refilling dual-purpose device for downhole includes an outer pipe 1, an inner base pipe, a ring-shaped stepping motor, a threaded pipe 6 and a valve sleeve device, and the wall of the outer pipe 1 is provided with vertically arranged The valve port 7, the valve port 7 presents a rectangular or trapezoidal shape arranged vertically in six rows. In the recharge state, the recharge water is recharged to the aquifer through the valve port 7 of the outer pipe 1.
[0021] Further, the annular stepping motor is located in the annular cavity formed by the outer tube 1 and the inner base tube, and the inner base tube includes an upper inner base tube 4 and a lower inner base tube 11, and the upper inner base tube 4 and the lower inner base tube 11 are threadedly connected with both ends of the outer pipe 1 respectively, and the inner base pipe is separately arranged, which facilitates the installation of the ...

The invention provides an underground electric control water pumping and re-injection dual-purpose device, which comprises an outer pipe, an inner base pipe, an annular step motor, a threaded pipe and a valve sleeve device, wherein a valve opening in vertical arrangement is formed in the outer pipe, the inner base pipe comprises an upper inner base pipe and a lower inner base pipe, an annular step motor rotor is arranged on the upper inner pipe in a sleeving way and can flexibly rotate, an annular motor stator is fixedly arranged on the inner wall surface of the outer pipe, an annular motor output shaft is connected with the annular threaded pipe, the vertical moving of the threaded pipe in the vertical direction is regulated through the moving of the output shaft, the valve sleeve device comprises a valve ring, a valve rod and a plug piston, and is connected with the threaded pipe, the valve ring and the plug piston through the valve rod, and the valve sleeve device is used for opening and closing the valve opening and a water supply opening of the lower inner base pipe. The underground electric control water pumping and re-injection dual-purpose device has the advantages that the vertical movement of the valve sleeve device is controlled through the annular step motor for regulating the water pumping and re-injection mode, in addition, the re-injection flow rate can be precisely and continuously regulated, the structure is compact, the automatic control degree is high, and good application prospects are realized.
Description
technical field [0001] The invention belongs to the technical field of underground manual recharging control devices, and in particular relates to an underground electronically controlled pumping and recharging dual-purpose device. Background technique [0002] With the rapid development of social economy, the contradiction between supply and demand of water resources is very prominent, groundwater is over-exploited, and many areas have a series of ecological and environmental geological problems such as continuous decline of groundwater level and land subsidence. Faced with the above problems, artificial replenishment of groundwater is more active and effective The strategy is an important technical means to maintain the balance of groundwater resource acquisition and recharge. At present, artificial recharge of groundwater is mainly done by well irrigation. How to improve the quality and efficiency of well recharge to achieve both pumping and recharge, the downhole control...
