Description
Technical Field

Background
When the well is drilled, whether a water filtering pipe is required to be installed or not is judged according to the soil structure of the well wall, certain hard cracks and solution gap aquifer well walls are stable and loose fillers are not needed, the water filtering pipe is not required to be installed when water is pumped, loose pore aquifers or broken bedrock aquifers are required to be installed, the water filtering pipe is suitable for water inlet, the water filtering pipe can prevent particles of soil or rock around the well walls from flowing into the well, and meanwhile, the functions of supporting and protecting the well walls are also achieved, so that the water pumping hole can be used normally. Cement gravel water filtering pipes are also commonly used in agricultural water supply wells, and brick-wood well walls of civil wells actually play roles in filtering water and purifying water resources.
The existing mode of fixing the submersible pump is to fix the water outlet pipe at the wellhead mostly, and the pump can swing and axially float greatly due to the fact that the axial force and the radial force of the pump change greatly when the submersible pump is started and closed, and the submersible pump is poor in stability due to the fact that the submersible pump collides with a well wall, a wear pull rope, a cable and the water outlet pipe.
There is also a mode of fixing the submersible pump in the well, for example, chinese patent No. CN21711155027.8, entitled "a submerged pump downhole fixing mechanism", which includes an elastic pull rope, a collar, a mounting belt, and a hanging chain connected with the mounting belt, where the mounting belt is used to fix the pump body of the submersible pump, the hanging chain is connected with a fixing device on the well, the elastic pull rope is provided with several groups with the collar, in each group, the elastic pull rope is provided with several, the collar is provided with one, one end of the elastic pull rope is connected to the well wall, the other end of the elastic pull rope is circumferentially and uniformly connected to the side surface of the collar, the collar is used to suit the submersible pump, and the ends of all pull ropes at the end where the elastic pull rope is connected with the well wall are located on the same horizontal circumference. When the submersible pump is used, the pump body with the fixed submersible pump is installed, then the submersible pump penetrates through the plurality of lantern rings from top to bottom, and the hanging chains are connected with the fixing device on the well, so that the submersible pump is fixed in the well.
The scheme of the patent needs to lift the elastic pull rope fixed on the well wall, and because well water exists in the well, the elastic pull rope is not easy to fix, and especially for a deep well, the elastic pull rope is difficult to fix, and in addition, because the position of the elastic pull rope is fixed, the position of the submersible pump in the well cannot be adjusted according to the water level change.
