[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] This embodiment relates to a pipeline repair propulsion device, one exemplary structure of which is as follows: Figures 1-6 As shown.

[0033] Overall, such as Figures 1-3 As shown, the pipeline repair propulsion device includes a base plate 2 with wheels 1, a power unit, and a drive unit located on one side of the power unit. The power unit includes a power unit 3 mounted on the base plate 2, a spiral-shaped shape memory metal 4, and a cooling pipe 5 located outside the shape memory metal 4. One end of the shape memory metal 4 is electrically connected to the power unit 3, and the other end is fixedly connected to a connecting block 6. The power unit 3 is connected to an external power source to provide voltage and heat the shape memory metal 4. The shape memory metal 4 responds rapidly to temperature changes, completing its shape transformation in a short time, thereby quickly generating propulsion force and reacting promptly, improving operational efficiency and accuracy.

[0034] In this invention, the driving device includes a drive wheel 7 and a driven wheel 8 rotatably mounted on the base plate 2. The drive wheel 7 and the driven wheel 8 are connected by a chain 9. The driven wheel 8 drives one set of wheels 1 on the base plate 2 to rotate. The driven wheel 8 has the same freewheel structure as the rear wheel 1 of a bicycle. That is, when the drive wheel 7 is driven to rotate forward by the shape memory metal 4, it can drive the driven wheel 8 to rotate forward, generating propulsion. When the drive wheel 7 is driven to rotate in reverse by the shape memory metal 4, the drive wheel 7 will not drive the driven wheel 8 to rotate. Therefore, the drive wheel 7 can propel the entire device within the pipe via the driven wheel 8, the wheels 1, etc.

[0035] Specifically, such as Figure 6As shown, the connecting block 6 is fixedly connected with a slide column 10 on one side of the driving wheel 7, the driving wheel 7 is coaxially fixedly connected with a slide rod 11, the slide rod 11 is provided with a slide groove 12 on one side of the connecting block 6, and the end of the slide rod 11 away from the connecting block 6 extends into the slide groove 12 and is in sliding connection with the slide groove 12. When the overall device advances in the direction of the driving wheel 7, the slide rod 11 is arranged below the shaft of the driving wheel 7; when the overall device advances in the direction of the driven wheel 8, the slide rod 11 is arranged above the shaft of the driving wheel 7. Since the energy applied to the memory metal 4 by the power is much easier than the energy applied by the cooling pipe 5, and since the driving force required when the driving wheel 7 rotates in the positive direction is greater than the driving force required when the driving wheel 7 rotates in the reverse direction, the above arrangement can always drive the driving wheel 7 to rotate in the positive direction when the memory metal 4 is heated by the power.

[0036] In this embodiment, as shown in the figure, Figures 4-5 The cooling pipe 5 is spirally arranged outside the memory metal 4, the cooling pipe 5 has an inlet pipe and an outlet pipe, and is in communication with the external cooling system through the inlet pipe and the outlet pipe. By spirally sleeving the cooling pipe 5 outside the memory metal 4, the memory metal 4 can be better cooled.

[0037] In addition, a control unit can be provided to control the power supply unit 3 and the cooling system, control the discharge of the power supply unit 3 and the release of the cooling system, so as to accurately control the heat and cooling degree of the memory metal 4, and realize the accurate expansion and contraction of the memory metal 4.

[0038] In this embodiment, the driven wheel 8 is coaxially fixedly connected with a connecting rod 13 along the axial direction, and the two ends of the connecting rod 13 are fixedly connected with the shafts of the corresponding wheels 1. The connecting rod 13 connects the driven wheel 8 and the wheels 1, and when the driven wheel 8 rotates, the wheels 1 are driven to rotate by the connecting rod 13.

[0039] In addition, a connecting frame 14 fixedly connected with the bottom plate 2 is further included, the connecting frame 14 is sleeved outside the memory metal 4, one end of the connecting frame 14 is fixedly connected with the power supply unit 3, and the cooling pipe 5 is sleeved outside the connecting frame 14. The connecting frame 14 supports the power supply unit 3 and the cooling pipe 5, and the inlet pipe and the outlet pipe are both flexible pipes, which facilitates the overall propulsion of the device.

[0040] In addition, a plurality of long holes 15 are formed in the connecting frame 14 along the axial direction. The long holes 15 can facilitate the cooling of the memory metal 4 by the cooling pipe 5.

[0041] In the embodiment, the bottom plate 2 is connected with a protective shell 16. The protective shell 16 can protect all the devices in the embodiment as a whole, and the tail of the protective shell 16 is fixedly connected with a hanging platform 17. The pipeline repair material can be hung or placed on the hanging platform 17. Of course, the hanging platform 17 can not be used, and the pipeline repair material can be directly bonded, hung or placed on the bottom plate 2 for conveying or advancing.

[0042] It should be particularly noted that the structure of the power unit 3 and the connection structure of the power unit 3 and the memory metal 4 are prior art, and the structure can refer to the structure of “Hot Quick”. The cooling system is also prior art, and the medium entering the cooling pipe 5 can be air, water or liquid nitrogen. The cooling system has a power source for driving the medium to circulate in the cooling pipe 5. The connecting block 6 is non-conductive and high-temperature resistant, and is connected with the memory metal 4 by using conventional technologies, such as welding, bonding, hanging or clamping.

[0043] The working process of the embodiment is as follows:

[0044] First, the pipeline repair material is bonded, hung or placed on the bottom plate 2 or the hanging platform 17. Then, the whole device is placed into one end of the pipeline, and the power unit 3 and the cooling system are intermittently started to repeatedly heat and cool the memory metal 4. When the memory metal 4 is heated by the power unit 3, the memory metal 4 shrinks, and the memory metal 4 drives the connecting block 6 and the slide column 10 on the connecting block 6 to move towards the driven wheel 8 (when the direction of the driving wheel 7 is taken as the forward direction). When the slide column 10 moves, the slide column 10 also slides in the sliding groove 12, applies force to the sliding groove 12, and drives the sliding rod 11 to rotate in the counterclockwise direction of the driving wheel 7, thereby driving the driving wheel 7 to rotate in the counterclockwise direction. After the driving wheel 7 rotates, the driven wheel 8 is driven to rotate by the chain 9, and finally the connecting rod 13 drives the wheel 1 to rotate in the counterclockwise direction of the driving wheel 7, thereby advancing in the pipeline. When the memory metal 4 is cooled by the cooling pipe 5, the memory metal 4 elongates, and the memory metal 4 drives the connecting block 6 and the slide column 10 on the connecting block 6 to move towards the driving wheel 7 (when the direction of the driving wheel 7 is taken as the forward direction). When the slide column 10 moves, the slide column 10 also slides in the sliding groove 12, applies force to the sliding groove 12, and drives the sliding rod 11 to rotate in the clockwise direction of the driving wheel 7, thereby driving the driving wheel 7 to rotate in the clockwise direction. After the driving wheel 7 reverses, the driven wheel 8 does not rotate because it is a freewheel structure of a bicycle. When the memory metal 4 repeatedly shrinks and elongates, the wheel 1 can be continuously driven to rotate by the structures.

[0045] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
