Description

Technical Field

[0001] The utility model relates to the technical field of removing blockages, in particular to a drainage pipe dredging device. Background Art

[0002] A drain pipe dredging device refers to a device for breaking and unclogging the obstruction inside the pipe after the pipe is blocked. It has a wide range of applications. When a municipal drain pipe is blocked, the drain pipe dredging device is used to dredge it. The Chinese utility model patent, authorization announcement number "CN213448824U", discloses a municipal pipe dredging device, including a base and a mounting seat, wherein locking universal wheels are fixedly installed at the four corners of the bottom of the base, a mounting shell is slidably connected to the interior of the base, a dredging motor is fixedly installed to the interior of the mounting shell, a rotating rod is fixedly connected to the driving end of the dredging motor, and a crushing tooth is fixedly connected to the end of the rotating rod away from the mounting shell, a sliding rod is fixedly installed to the interior of the base, two sliding blocks are slidably connected to the sliding rod, and shock-absorbing springs are fixedly installed on the opposite sides of the two sliding blocks, and the end of the shock-absorbing spring away from the sliding block is fixedly connected to the inner wall of the base, and a support rod is rotatably connected to the sliding block.

[0003] The above technical solution drives the two sliders to move opposite to each other through the downward movement of the mounting shell, compressing the shock-absorbing spring, and then pushing the two sliders back to their original positions through the elastic force of the shock-absorbing spring, thereby achieving the effect of reducing the vibration of the device. The structure is simple and the shock-absorbing effect is good, which is beneficial to extending the service life of the dredging motor. However, the above technical solution still has certain defects. There are inevitably some relatively hard garbage inside the drain pipe, such as some hard stones. Although the dredging device can reduce vibration through the shock-absorbing spring, when the drill bit and the crushing teeth hit the stone, vibration will be generated, and the rotating rod is directly connected to the output end of the motor. The vibration will be transmitted to the motor, which is easy to damage the motor and thus affect the service life of the motor. For this reason, the utility model proposes a new solution.

[0030] See also Figure 1-5 The utility model provides a technical solution: a drain pipe dredging device, comprising a drain pipe dredging device base 1, the upper end of which is fixedly connected to a fixing block 2, the upper end of the drain pipe dredging device base 1 is fixedly connected to a dredging device controller 3, the upper end of the drain pipe dredging device base 1 is provided with a shock absorbing assembly, the shock absorbing assembly comprises a fixing frame 17, the fixing frame 17 is fixedly connected to the upper end of the fixing block 2, the inner wall of the fixing frame 17 is symmetrically rotatably connected to two dampers 16, the opposite surfaces of the two dampers 16 are rotatably connected to a drill rod connecting sleeve 15, the inside of the drill rod connecting sleeve 15 is rotatably connected to a drill rod 14, the upper end of the dredging device controller 3 is fixedly connected to a rotating shaft bracket 7, the inside of the rotating shaft bracket 7 is rotatably connected to a rotating shaft 9, the opposite surfaces of the drill rod 14 and the rotating shaft 9 are rotatably connected to a second connecting block 12 and a first connecting block 11 respectively, and the surfaces of the first connecting block 11 and the second connecting block 12 are fixedly connected to a plurality of rubber strips 13.

[0031] A plurality of crushing blades 18 are fixedly connected to the surface of the drill rod 14, a drill bit is fixedly connected to the end of the drill rod 14 away from the drill rod connecting sleeve 15, a drive motor seat 6 is fixedly connected to the upper end of the dredging device controller 3, a drive motor 8 is fixedly connected to the upper end of the drive motor seat 6, the drive motor 8 is electrically connected to the dredging device controller 3, a magnetic coupler 10 is fixedly connected to the output end of the drive motor 8, and the end of the magnetic coupler 10 away from the drive motor 8 is fixedly connected to the surface of the rotating shaft 9.

[0032] The right end of the drain pipe clearing device base 1 is fixedly connected to a connecting rod 4, and the end of the connecting rod 4 away from the drain pipe clearing device base 1 is fixedly connected to a handle 5, and two grooves are provided on the surface of the handle 5. Four wheels 19 are fixedly installed at the lower end of the drain pipe clearing device base 1.

[0033] When using the device, first push the device into the drain pipe through the handle 5 and the connecting rod 4. Since the handle 5 has two grooves on its surface, it is convenient to hold with both hands to improve the stability of the device. Start the drive motor 8 to drive the magnetic coupler 10 to rotate. The magnetic coupler 10 drives the rotating shaft 9 to rotate inside the rotating shaft bracket 7. The rotating shaft 9 drives the first connecting block 11 to rotate. The first connecting block 11 drives the rubber strip 13 and then drives the second connecting block 12 to rotate. The second connecting block 12 drives the drill rod 14 to rotate inside the drill rod connecting sleeve 15. The drill rod 14 drives the crushing blade 18 and the drill bit to rotate. The use of the drill bit and the crushing blade 18 facilitates the crushing of garbage inside the drain pipe.

[0034] When the drill bit and the crushing blade 18 hit the stone, vibration will occur. The vibration is transmitted to the drill rod connecting sleeve 15 through the drill rod 14 and is reduced by the damper 16.

[0036] Furthermore, by symmetrically arranging two dampers 16 and connecting the rotating shaft 9 and the drill rod 14 through the rubber strip 13, when the drill rod 14 vibrates, the rubber strip 13 can buffer and absorb the vibration and block the vibration, thereby compensating for the displacement caused by the vibration of the device, thereby further buffering the vibration of the drive motor 8 and avoiding damage to the drive motor 8, which is beneficial to improving the service life of the drive motor 8.

[0037] The drive motor 8 and the rotating shaft 9 are connected by a magnetic coupling 10. The magnetic coupling 10 has an isolation effect. When the crushing blade 18 is stuck by a stone, the drive motor 8 and the rotating shaft 9 can be disconnected, thereby protecting the drive motor 8 from being burned, adjusting the load speed, improving efficiency, reducing the load of the drive motor 8, and then protecting the drive motor 8 and increasing the service life of the device.

[0038] Working principle: When using the device, first push the device into the drain pipe through the handle 5 and the connecting rod 4. Since the surface of the handle 5 has two grooves, it is convenient to hold with both hands to improve the stability of the device. Start the drive motor 8 to drive the magnetic coupler 10 to rotate, and the magnetic coupler 10 drives the rotating shaft 9 to rotate inside the rotating shaft bracket 7. The rotating shaft 9 drives the first connecting block 11 to rotate, and the first connecting block 11 drives the rubber strip 13 and then drives the second connecting block 12 to rotate. The second connecting block 12 drives the drill rod 14 to rotate inside the drill rod connecting sleeve 15, and the drill rod 14 drives the crushing blade 18 and the drill bit to rotate. The use of the drill bit and the crushing blade 18 facilitates the crushing of garbage inside the drain pipe.

[0039] When the drill bit and the crushing blade 18 hit the stone, vibration will occur. The vibration is transmitted to the drill rod connecting sleeve 15 through the drill rod 14 and is reduced by the damper 16. The rotating shaft 9 and the drill rod 14 are connected by the rubber strip 13. When the drill rod 14 vibrates, the rubber strip 13 can buffer and absorb the vibration and block the vibration, so as to compensate for the displacement caused by the vibration of the device.

[0040] When the drill bit and the crushing blade 18 hit the stone, the crushing blade 18 may be stuck. When the crushing blade 18 is stuck, the magnetic coupler 10 can automatically disconnect the connection between the drive motor and the rotating shaft 9, thereby protecting the drive motor 8 from being burned. The magnetic coupler 10 has an isolation effect, which can avoid problems such as friction, wear and vibration caused by the transmission of torque.
