Problems solved by technology

However, due to maintenance and construction quality problems, leakage often occurs. Because it is buried underground, it is sometimes difficult to find, and it often pollutes the soil and groundwater environment along the line. Therefore, the investigation of underground pipeline leakage has become a top priority for environmental protection departments.
[0003] The detection of underground pipelines is a big problem. At present, there is no very mature detection method in the world. Before the retrieval, on-site excavation and chemical exploration were mainly used for investigation. The newly developed detection technologies include natural potential method and ground penetrating radar. For underground pipelines with long distribution, a lot of work needs to be arranged, a huge amount of money is spent, and the work cycle is long. Therefore, there is an urgent need for a tool that can work in different environments such as silt or water flow, and is used for underground pipelines and river silt detection. robot device

Embodiment 1

[0038] A screw propulsion device for a pipeline inspection robot. The device in this embodiment is especially suitable for the inspection of mud pipelines. Its overall structure is as follows: figure 1 As shown, it includes several screw propulsion cabins, driving mechanisms and steering mechanisms. The screw propulsion cabin 5, the third steering cabin 6, the fourth screw thrust cabin 7 and the tail thrust cabin 8; and the first screw thrust cabin 1, the second screw thrust cabin 3, the third screw thrust cabin 5 and the fourth screw thrust cabin 7 have the same structure, and the first steering cabin 2 and the third steering cabin 6 have the same structure.

[0039] A cabin partition 16 is set between the first screw propulsion cabin 1 and the pipeline inspection robot 48, as figure 2As shown, a screw power ring 18 is installed on the outside of the cabin inner wall 19 of the first screw propulsion cabin 1, and the inside and outside of the screw power ring 18 are provided...

Embodiment 2

[0048] A screw propulsion device for a pipeline inspection robot. The device in this embodiment is especially suitable for the inspection of pipelines for transporting water. The main structure of this embodiment is the same as that in Embodiment 1, except that the screw propulsion at the tail of this embodiment is Cabin, namely the back of the 4th screw propulsion cabin 7 has added a setting a tail propelling cabin 8, as Figure 8 As shown, a power tail 31 is installed on the power transmission shaft in the tail propelling cabin 8, and the power tail 31 is made up of three blades, and a filter screen 33 is installed at the afterbody of the tail propelling cabin 8.

[0049] In this embodiment, the way of information exchange between the pipeline inspection robot 48 and ground operators is different from the wireless signal exchange in Embodiment 1. An external interface 41 is arranged on the outside of the rear propelling cabin 8 of the present embodiment, and the external inte...

The spiral propelling device comprises a plurality of spiral propelling cabins, a driving mechanism and a directionturning mechanism, wherein spiral teeth are arranged on the outer sides of the spiral propelling cabins, the spiral propelling cabins are connected through direction turning cabins, and the side wallsof the direction turning cabins are rubber telescopic rings; the direction turning mechanism comprises a plurality of direction control rods which are arranged in the axial direction of the spiral propelling device and supports fixed on the inner walls of the spiral propelling cabins; the two ends of the direction control rods are movably connected with the supports, a direction turning motor anda telescopic device controlled to stretch out and draw back by the direction turning motor are connected in the middle of each direction control rod; the driving mechanism comprises driving force motors arranged inside the direction turning cabins, main rotating shafts and power rotating wheels, wherein the main rotating shafts are connected with transmission shafts of the driving force motors, and the power rotating wheels are connected with the main rotating shafts; and the power rotating wheels are arranged inside the spiral propelling cabins and drive the spiral teeth to rotate, and powerrod direction turning gears are arranged on the main rotating shafts. Compared with the prior art, the spiral propelling device has the advantages of being wide in application range, easy to operate,convenient to measure and the like.

Description

technical field [0001] The invention relates to the technical field of pipeline inspection robots, in particular to a screw propulsion device of a pipeline inspection robot. Background technique [0002] In the process of production and life, people often use underground pipelines to transport raw materials and waste water containing harmful components. These pipelines, especially sewage pipelines, have contributed to the protection of the environment. However, due to maintenance and construction quality problems, leakage often occurs. Because it is buried underground, it is sometimes difficult to find, and it often pollutes the soil and groundwater environment along the line. Therefore, the investigation of underground pipeline leakage has become an urgent task for the environmental protection department. [0003] The detection of underground pipelines is a big problem. At present, there is no very mature detection method in the world. Before the retrieval, on-site excavati...
