[0006] The annular power device comprises a rotating motor fixed to the end of the outer wall of the sleeve, and the output shaft of the rotating motor is connected to the rotating main shaft through a transmission mechanism to drive the rotating main shaft to rotate.

[0007] The transmission mechanism adopts belt transmission, chain transmission or gear transmission.

[0008] The telescopic bracket mechanism includes a first telescopic rod, a second telescopic rod and a third telescopic rod arranged at the end of a rotating main shaft; the last telescopic rod of the second telescopic rod adopts an L-shaped bending structure; the last telescopic rod of the first telescopic rod and the third telescopic rod adopts an L-shaped bending structure or a lockable rotating structure; the first telescopic rod, the second telescopic rod and the third telescopic rod are used in conjunction with each other to install a rope saw device.

[0010] The saw rope is a diamond beaded rope.

[0011] A method for opening a drainage system inspection well using a high-efficiency hole opening device comprises the following steps:

[0012] Step 1: Mark the hole location:

[0013] Determine the center position of the hole to be opened in the inspection well and the diameter of the hole to be opened, mark the location of the hole to be opened, and draw the marking line of the opening to be opened;

[0014] Step 2: Drill holes for equipment installation:

[0015] A hole is punched at the center of the intended hole position to form an equipment installation hole. The diameter of the equipment installation hole is determined according to the outer diameter of the rotating support device. The specific shape of the equipment installation hole should be consistent with the longitudinal protrusion structure on the outside of the sleeve to achieve the purpose of locking and prevent displacement;

[0016] Step 3: Drill the pre-punched holes for the wire saw:

[0017] A hole is made inward along the circumference of the marked opening mark line, thereby forming a pre-punched hole for the rope saw. The size of the pre-punched hole for the rope saw is based on the size of the saw rope after it is installed. The specific width of the hole is the distance between the outer edges of the two working wheels on the same side.

[0018] Step 4: Install the rotating support device:

[0019] Pass the rotating support device through the equipment installation hole at the center of the circle, and install the telescopic support mechanism and wire saw device of the equipment, but do not install the saw wire for the time being;

[0024] Step 7: Adjust the cutting position of the saw rope:

[0025] Adjust the angles of the first working wheel, auxiliary wheel and second working wheel and fix them. If necessary, adjust the length of the telescopic bracket mechanism and fix it again to ensure that the intersection of the saw rope and the inspection well is on the marked opening mark line;

[0026] Step 8: Equipment sawing operation:

[0027] Turn on the power supply and start the rope saw device. The rope saw device drives the saw rope to rotate and cut the concrete. At the same time, start the circumferential power device of the rotating support device, drive the rotating main shaft through the circumferential power device, and synchronously drive the telescopic support mechanism and the rope saw device to rotate around the center of the equipment installation hole through the rotating main shaft, thereby realizing the cutting of concrete. After the rotating main shaft rotates one circle, the corresponding hole will be cut on the inspection well;

[0028] During the cutting process, use a hose to continuously spray water on the saw wire to prevent the wire from being damaged by overheating;

[0029] Step 9: Remove the device:

[0030] When the entire circle is cut, cut off the power supply, stop spraying water for cooling, dismantle the equipment, and take out the reinforced concrete in the cutting circle.
