The upper side wall of the upper section of the well casing has an outwardly protruding mounting ring, and a well cover is installed on the top of the upper section of the well casing. A lateral connecting cylinder is provided on the side wall of the upper section of the well casing, and the lateral connecting cylinder is located below the outwardly protruding mounting ring. A cable clamping device is provided on the outwardly protruding mounting ring, and an adjusting rod is installed on the cable clamping device through an adjusting nut. A suspension rod is connected to the bottom of the adjusting rod through a first shackle, and a cable assembly is tied to the suspension rod. A lifting rod is connected to the bottom of the suspension rod through a second shackle, and a submersible pump is installed at the bottom of the lifting rod. The cable assembly is connected to the submersible pump. A seat ring is fixed on the lower section of the well casing, and a base assembly is fixed at the bottom of the seat ring.

[0007] The cable assembly includes power cables and control cables.

[0008] The power and control cables of the cable assembly are tied to the suspension rod with several rubber bands.

[0009] The top of the upper section of the well shaft is provided with an upper flange. The well cover is fixed to the upper flange with bolts. The middle of the well cover is provided with a through hole and a cable outlet device is installed above the through hole. The cable assembly extends out of the well cover through the cable outlet device.
