Description

Technical Field

[0001] This invention relates to the field of wastewater technology, specifically to a spiral underground wastewater pipeline dredging device. Background Technology

[0002] Wastewater refers to the portion of polluted water resources discarded after human use. Due to human dependence on water resources, the frequency of water use is increasing, leading to a growing volume of wastewater. Therefore, wastewater needs to be transported and centrally treated through underground sewage pipes to prevent its indiscriminate discharge into the environment and to reduce its pollution.

[0003] In the prior art, Chinese patent publication number CN211114055U discloses a spiral underground sewage pipe dredging and flushing device. This solution, through the setting of a spiral stirring rod, a first high-pressure nozzle and a second high-pressure nozzle, makes dredging more labor-saving, improves the working conditions of dredging workers and reduces labor intensity, and has high automation performance. Although the high-pressure nozzle can provide good impact force for dredging, some sewage impurities on the outside of the spiral stirring rod are easy to adhere to the outer wall of the high-pressure nozzle. The impact force of the high-pressure nozzle is difficult to impact its own exterior, resulting in the high-pressure nozzle being easily corroded and damaged. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a spiral underground sewage pipe dredging device, which solves the problem mentioned in the background technology that although the high-pressure nozzle can provide good impact force for dredging, sewage impurities on the outside of some spiral stirring rods are easily attached to the outer wall of the high-pressure nozzle, making it difficult for the impact force of the high-pressure nozzle to impact its own exterior, resulting in the high-pressure nozzle being easily corroded and damaged.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a spiral underground sewage pipe dredging device, comprising a sewage pipe, wherein a spiral filter device is installed inside the sewage pipe, and the spiral filter device comprises:

[0008] A rotating shaft has a spiral plate fixedly mounted on its outer wall, an annular filter plate fixedly mounted on the spiral plate, and a high-pressure nozzle fixedly mounted on the annular filter plate. A water pump is slidably mounted on the inner wall of the top of the sewage pipe, and a disc is fixedly mounted at the bottom of the water pump. A hanging rod is rotatably mounted on the bottom of the disc, and a drive motor is fixedly mounted inside the disc. The top of the rotating shaft is fixedly mounted at the output end of the drive motor. The output end of the high-pressure nozzle is in the same vertical plane as the outer wall of the annular filter plate. An elastic element is provided between the outer wall of the hanging rod and the outer wall of the bottom of the disc. When the rotating shaft drives the spiral plate and the high-pressure nozzle to rotate and perform sludge removal, the annular filter plate can provide good protection for the high-pressure nozzle. At the same time, the impact force of the high-pressure nozzle can push the hanging rod to swing, improving the agitation and sludge removal ability of the spiral plate.

[0009] Preferably, the drooping rod is provided with an elastic sliding device, which includes a groove. The groove is formed on the drooping rod and faces outward from the high-pressure nozzle. An arc-shaped rod is rotatably mounted on the outer wall of the drooping rod. An elastic element is provided between the outer wall of the arc-shaped rod and the outer wall of the drooping rod. A ball is rotatably mounted at the bottom of the arc-shaped rod. A semi-circular protrusion is fixedly mounted on the outer wall of the ball. The bottom of the arc-shaped rod is rotatably mounted on the top of the pressure rod. The bottom of the pressure rod is rotatably mounted on the outer wall of the guide plate. The guide plate is slidably sleeved on the outer wall of the drooping rod. The end of the guide plate near the spiral plate is set to be inclined downward. When the rotating shaft drives the spiral plate to rotate, the ball can intermittently knock between the semi-circular protrusion and the outer wall of the spiral plate, thereby loosening the sewage impurities on the surface of the spiral plate and preventing sticky adhesion.

[0010] Preferably, the guide plate is provided with an inertial swing device, which includes a support rod. One end of the support rod is fixedly installed on the end of the guide plate away from the spiral plate, and a rotating column is rotatably installed on the other end of the support rod. A swing rod is fixedly installed on the rotating column, and a friction ball is fixedly installed on the end of the swing rod away from the rotating column. The friction ball is located near the outside of the drooping rod. When the drooping rod swings outward due to the impact force of the high-pressure nozzle, the reverse swing of the friction ball can knock and vibrate the outer wall of the drooping rod, promoting the downward movement of sewage impurities in the groove on the drooping rod.

[0011] Preferably, an auxiliary rotating device is provided on the outside of the annular filter plate. The auxiliary rotating device includes an elastic rod, which is elastically rotatably mounted on the outer wall of the annular filter plate. The elastic rod is located above the high-pressure nozzle. A rotating tube is rotatably mounted on the outer wall of the end of the elastic rod away from the annular filter plate. Blades are fixedly mounted on the outer wall of the rotating tube. A long rod is fixedly mounted on the top of the elastic rod, with the top of the long rod positioned near the outside of the hanging rod. A short rod is fixedly mounted on the outer wall of the long rod, facing outwards from the annular filter plate. When the high-pressure nozzle is working, the rotation of the elastic rod can drive the long rod to impact the hanging rod, while the short rod can impact the annular filter plate, promoting the agitation of the spiral plate.

[0012] (III) Beneficial Effects

[0013] This invention provides a spiral-type underground sewage pipe dredging device. It has the following beneficial effects:

[0014] (1) The spiral underground sewage pipe dredging equipment is equipped with a spiral filter device. When the rotating shaft drives the spiral plate and the high-pressure nozzle to rotate and dredge, the spiral plate will also drive the annular filter plate to rotate. The high-pressure nozzle itself is located inside the annular filter plate, so that the annular filter plate can provide good protection for the high-pressure nozzle. At the same time, the impact force of the high-pressure nozzle can push the hanging rod to swing, thereby improving the stirring and dredging ability of the spiral plate.

[0015] (2) The spiral underground sewage pipe dredging equipment is equipped with an elastic sliding device. When the rotating shaft drives the spiral plate to rotate, the outer wall of the spiral plate will push the ball and the arc rod to move upward. The ball can then intermittently strike the outer wall of the spiral plate through the semi-circular protrusion, thereby loosening the sewage impurities on the surface of the spiral plate and preventing sticky adhesion.

[0016] (3) The spiral underground sewage pipe dredging equipment is equipped with an inertial swing device. When the pendant swings outward due to the impact of the high-pressure nozzle, the swing rod and the friction ball will swing in the opposite direction due to inertia. The reverse swing of the friction ball can knock and vibrate the outer wall of the pendant, promoting the downward movement of sewage impurities in the groove of the pendant.

[0017] (4) The spiral underground sewage pipe dredging equipment is equipped with an auxiliary rotating device. When the high-pressure nozzle is working, the impact force of the high-pressure nozzle will push the elastic rod to rotate upward. The elastic rod can drive the rotating pipe to move accordingly. The impact force can drive the blade to rotate the rotating pipe. When the elastic rod rotates, it can drive the long rod to hit the hanging rod. At the same time, the short rod can hit the annular filter plate, which promotes the stirring ability of the spiral plate. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-7 This invention provides a technical solution: a spiral underground sewage pipe dredging device, comprising a sewage pipe 1, wherein a spiral filter device is installed inside the sewage pipe 1, and the spiral filter device includes:

[0028] A rotating shaft 31 has a spiral plate 32 fixedly mounted on its outer wall. An annular filter plate 33 is fixedly mounted on the spiral plate 32, and a high-pressure nozzle 34 is fixedly mounted on the annular filter plate 33. A water pump is slidably mounted on the inner top wall of the sewage pipe 1. A disc 35 is fixedly mounted at the bottom of the water pump, and a hanging rod 36 is rotatably mounted on the bottom of the disc 35. A drive motor 2 is fixedly mounted inside the disc 35. The top of the rotating shaft 31 is fixedly mounted to the output end of the drive motor 2. The output end of the high-pressure nozzle 34 is on the same vertical plane as the outer wall of the annular filter plate 33. An elastic element is provided between the outer wall of the drooping rod 36 and the bottom outer wall of the disc 35. With the spiral filter device, when the rotating shaft 31 drives the spiral plate 32 and the high-pressure nozzle 34 to rotate and clean up the silt, the spiral plate 32 will also drive the annular filter plate 33 to rotate. The high-pressure nozzle 34 is located inside the annular filter plate 33, so that the annular filter plate 33 can provide good protection for the high-pressure nozzle 34. At the same time, the impact force of the high-pressure nozzle 34 can push the drooping rod 36 to swing, thereby improving the agitation and silt-cleaning ability of the spiral plate 32.

[0029] An elastic sliding device is provided on the drooping rod 36, including a groove 41. The groove 41 is formed on the drooping rod 36 and faces outwards from the high-pressure nozzle 34. An arc-shaped rod 42 is rotatably mounted on the outer wall of the drooping rod 36. An elastic element is provided between the outer wall of the arc-shaped rod 42 and the outer wall of the drooping rod 36. A ball 43 is rotatably mounted on the bottom of the arc-shaped rod 42. A semi-circular protrusion 44 is fixedly mounted on the outer wall of the ball 43. The bottom of the arc-shaped rod 42 is rotatably mounted on the top of the pressure rod 45. The bottom of the pressure rod 45 is rotatably mounted on the outer wall of the guide plate 46. The guide plate 46 is slidably sleeved on the outer wall of the drooping rod 36. The end of the guide plate 46 near the spiral plate 32 is inclined downwards. An inertial swing device is provided on the guide plate 46. The oscillating device includes a support rod 51. One end of the support rod 51 is fixedly installed on the end of the guide plate 46 away from the spiral plate 32. The other end of the support rod 51 is rotatably installed with a rotating column 52. An oscillating rod 53 is fixedly installed on the rotating column 52. A friction ball 54 is fixedly installed on the end of the oscillating rod 53 away from the rotating column 52. The friction ball 54 is located near the outside of the hanging rod 36. With the provision of an elastic sliding device, when the rotating shaft 31 drives the spiral plate 32 to rotate, the outer wall of the spiral plate 32 will push the ball 43 and the arc rod 42 to move upward. The ball 43 can then intermittently strike the outer wall of the spiral plate 32 through the semi-circular protrusion 44, thereby loosening the sewage impurities on the surface of the spiral plate 32 and preventing sticky adhesion.

[0030] An auxiliary rotating device is provided on the outside of the annular filter plate 33. The auxiliary rotating device includes an elastic rod 61, which is elastically rotatably mounted on the outer wall of the annular filter plate 33. The elastic rod 61 is located above the high-pressure nozzle 34. A rotating tube 62 is rotatably mounted on the outer wall of the end of the elastic rod 61 away from the annular filter plate 33. A blade 63 is fixedly mounted on the outer wall of the rotating tube 62. A long bar 64 is fixedly mounted on the top of the elastic rod 61. The top of the long bar 64 is located near the outside of the hanging rod 36. A short bar 6 is fixedly mounted on the outer wall of the long bar 64. 5. The short rod 65 is positioned towards the outside of the annular filter plate 33. With the aid of an auxiliary rotating device, when the high-pressure nozzle 34 is working, the impact force of the high-pressure nozzle 34 will push the elastic rod 61 to rotate upward. The elastic rod 61 can then drive the rotating tube 62 to move accordingly. The impact force can drive the blade 63 to rotate the rotating tube 62. When the elastic rod 61 rotates, it can drive the long rod 64 to impact the hanging rod 36. At the same time, the short rod 65 can impact the annular filter plate 33, promoting the agitation ability of the spiral plate 32.

[0031] During operation (or use), the spiral filter device is installed, and the drive motor 2 is started to drive the rotating shaft 31 to rotate. At the same time, the external propulsion device controls the water pump and the drive disc 35 to move along the sewage pipe 1. The water pump can supply water to the high-pressure nozzle 34 through the external water source. The rotation of the rotating shaft 31 drives the spiral plate 32 to rotate accordingly. The rotating shaft 31 drives the high-pressure nozzle 34 to rotate accordingly when it is pressing. Subsequently, the rotation of the spiral plate 32 will also drive the annular filter plate 33 to rotate accordingly, so that the annular filter plate 33 and the high-pressure nozzle 34 rotate synchronously. Furthermore, the high-pressure nozzle 34 is located inside the annular filter plate 33, which ultimately provides good protection for the high-pressure nozzle 34. At the same time, when the high-pressure nozzle 34 rotates to the position of the drooping rod 36, the groove 41 on the drooping rod 36 can increase the contact area of ​​the water flow, so that the impact force of the high-pressure nozzle 34 can push the drooping rod 36 to swing outward through the groove 41. Subsequently, when the high-pressure nozzle 34 and the drooping rod 36 are misaligned, the drooping rod 36 will return to its initial position due to the elastic force of the elastic element, ultimately improving the stirring and sludge removal ability of the spiral plate 32.

[0032] By incorporating an elastic sliding device, when the rotating shaft 31 drives the spiral plate 32 to rotate, the spiral plate 32's own spiral rotation relative to the rotating shaft 31 will generate up-and-down reciprocating motion. This causes the outer wall of the spiral plate 32 to push the ball 43 and the arc-shaped rod 42 upward. When the spiral plate 32 moves downward, the arc-shaped rod 42 will move downward following the spiral plate 32 due to the elastic force of the elastic element. The up-and-down movement of the spiral plate 32 will generate rotation following the rotating shaft 31, resulting in friction between the spiral plate 32 and the semi-circular protrusion 44. This allows the semi-circular protrusion 44 to drive the ball 43 to rotate. Ultimately, the ball 43, through the rotation of the semi-circular protrusion 44, can intermittently tap the outer wall of the spiral plate 32, thereby loosening sewage impurities on the surface of the spiral plate 32 and preventing sticky adhesion. Furthermore, the arc-shaped rod 42 follows the ball 43... When swinging, the arc-shaped rod 42 can drive the top of the pressure rod 45 to move accordingly, so that the bottom of the pressure rod 45 can push the outer wall of the guide plate 46 to slide up and down. With the inertial swinging device, when the drooping rod 36 swings outward due to the impact force of the high-pressure nozzle 34, the drooping rod 36 will drive the swinging rod 53 and the friction ball 54 to swing accordingly through the guide plate 46. At the same time, the guide plate 46 will also drive the swinging rod 53 and the friction ball 54 to move accordingly due to the sliding of the arc-shaped rod 42. During the following movement, the swinging rod 53 and the friction ball 54 will swing in the opposite direction of the movement due to inertia. The reverse swing of the friction ball 54 can drive the swinging rod 53 to rotate, so that the friction ball 54 can knock and vibrate the outer wall of the drooping rod 36, promoting the downward movement of sewage impurities in the groove 41 of the drooping rod 36.

[0033] With the auxiliary rotation device, when the high-pressure nozzle 34 is working, the impact force of the high-pressure nozzle 34 will push the elastic rod 61 to rotate upward. The elastic rod 61 can then drive the rotating tube 62 to move accordingly. The impact force can also drive the blade 63 to rotate the rotating tube 62, improving the agitation ability of the annular filter plate 33. At the same time, the elastic rod 61 drives the long rod 64 to move upward, causing the long rod 64 to impact the outside of the hanging rod 36, causing the hanging rod 36 to vibrate. Meanwhile, the short rod 65 can impact the annular filter plate 33, ultimately promoting the agitation ability of the spiral plate 32.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
