Description

Technical Field

[0001] This utility model relates to the technical field of sewer unblocking devices, specifically a magnetic shaft drill. Background Technology

[0002] Drainage pipes are essential in daily life. Existing spindle drills encounter resistance when unclogging pipes due to the cutting head getting stuck at the front end, and the flexible shaft drive system at the rear end causing cutting and entanglement, which can easily lead to danger and is troublesome to deal with. Therefore, it is necessary to develop a magnetic spindle drill to solve the above problems. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a magnetic spindle drill to solve the existing inconvenient technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnetic spindle drill, characterized in that it includes a dredging section and a tail section; the dredging section and the tail section are connected by a stainless steel outer sheath; the stainless steel outer sheath is provided with a magnetic cavity and two symmetrical bearing cavities inside;

[0005] The unblocking section comprises a flexible shaft and a spring sleeve; one end of the flexible shaft is connected to a unblocking cutter head, and the other end is connected to a counteracting drive magnet; the unblocking cutter head is provided with a set screw; the flexible shaft is connected to the unblocking cutter head through the set screw; a bearing is installed on the flexible shaft near the counteracting drive magnet; the counteracting drive magnet is disposed in a magnetic cavity; the bearing is installed in a bearing cavity;

[0006] The tail section includes a flexible shaft core two and a spring-cushioned flexible shaft sheath; one end of the flexible shaft core two is connected to a counter-attraction drive magnet two, and the other end is connected to a tailstock mounting hole; a set screw two is installed on the tailstock mounting hole; the flexible shaft core two is connected to the tailstock mounting hole through the set screw two; a bearing two is connected to the flexible shaft core two near the counter-attraction drive magnet two; the counter-attraction drive magnet two is disposed in a magnetic cavity; the bearing two is installed in a bearing cavity;

[0007] Both the first and second opposing magnetic magnets are installed inside the magnetic cavity and are driven by magnetic attraction.

[0008] Furthermore, three supports are evenly distributed on the stainless steel outer sheath; wheels are connected to the supports.

[0009] Furthermore, a wireless camera is installed on the stainless steel outer sheath.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention connects the second flexible shaft core and the drive source through the tailstock connection hole, driving the second flexible shaft core to rotate. The second magnetic drive magnet rotates, and the magnetic force causes the first magnetic drive magnet to rotate as well, thereby driving the flexible shaft core to rotate. This drives the drain cleaning head to rotate and unclog the sewer. When the drain cleaning head gets stuck and the magnetic force is resisted, the second flexible shaft core continues to rotate, but the flexible shaft core does not rotate, and the tail section does not get tangled or jammed. After the stuck drain cleaning head is removed, the magnetic force continues to drive the drain cleaning.

[0012] In this utility model, three supports are evenly provided on the outer stainless steel sheath, and wheels are connected to the supports to support the utility model to move forward in the sewer.

[0013] The stainless steel outer sheath of this utility model is equipped with a wireless camera, which can observe the working status of the unclogging head and retract it in time when it gets stuck. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.
