[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up the pipeline inspection robot body, the pipeline inspection robot body can crawl in the pipeline. During the crawling process of the pipeline inspection robot body, the detection camera can be used to shoot and inspect the inside of the pipeline, and the captured images are transmitted to the external terminal. When the detection camera detects that the pipeline is misaligned, the external terminal controls the external alarm to turn on the alarm to remind workers to conduct timely maintenance;

[0019] 2. By setting a rotary high-pressure flushing mechanism, the rotary high-pressure flushing mechanism can spray water while rotating, and can perform all-round flushing of the sludge at the dislocation of the pipeline, so as to avoid the sludge adhering to the inner wall of the pipeline affecting the detection accuracy of the dislocation strength of the dislocation strength detection mechanism at the dislocation of the pipeline. By setting a ratchet transmission mechanism, the ratchet transmission mechanism makes the rotary high-pressure flushing mechanism rotate normally to flush the dislocation of the pipeline without driving the linkage mechanism and the columnar protective cover to rotate. After the sludge at the dislocation of the pipeline is flushed through the rotary high-pressure flushing mechanism, the rotary high-pressure flushing mechanism is controlled to rotate in the opposite direction. When the rotary high-pressure flushing mechanism rotates in the opposite direction, the linkage mechanism can be driven to rotate through the ratchet transmission mechanism, and the columnar protective cover can be driven to rotate through the linkage mechanism. When the columnar protective cover rotates, the expansion mechanism and the dislocation strength detection mechanism can be driven to rotate through the connecting rod, so that the dislocation strength detection mechanism can perform all-round detection of the dislocation strength of the dislocation of the pipeline, which is convenient for the staff to formulate a repair plan according to the actual dislocation strength of the pipeline;

[0020] 3. By setting an expansion mechanism, the expansion mechanism can control the two groups of dislocation strength detection mechanisms to extend and retract at the same time. When the dislocation strength detection mechanism is needed to perform dislocation strength detection on the dislocated part of the pipeline, the two groups of dislocation strength detection mechanisms are controlled to expand outward at the same time through the expansion mechanism. When the two groups of dislocation strength detection mechanisms both hit the inner wall of the pipeline, the displacement sensors on the two groups of dislocation strength detection mechanisms can be used to measure the degree of dislocation of the dislocated pipeline with the non-dislocated pipeline where the pipeline detection robot body is located as the center. When the pipeline is not dislocated, the values ​​detected by the two groups of displacement sensors are the same. When the pipeline is dislocated, the difference between the values ​​detected by the displacement sensors on the two symmetrically arranged groups of dislocation strength detection mechanisms divided by two is the dislocation distance of the pipeline. After the detection is completed, the two groups of dislocation strength detection mechanisms are controlled to retract inwardly through the expansion mechanism, so that the dislocation strength detection mechanism can be stored and protected, and the dislocation strength detection mechanism can be prevented from being damaged.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Examples, such as Figure 1-8As shown, a pipeline misalignment alarm device for underground pipe gallery management includes a pipeline detection robot body 1, a detection camera 2 and a water pipe 3 equidistantly installed on the outside of the pipeline detection robot body 1 in the axial direction. The pipeline detection robot body 1 can crawl in the pipeline. During the crawling of the pipeline detection robot body 1, the inside of the pipeline can be photographed and detected through the detection camera 2, and the photographed picture is transmitted to the external terminal. When the detection camera 2 detects that the pipeline is misaligned, the external terminal controls the external alarm to turn on the alarm to remind the workers to carry out timely maintenance. One end of the pipeline detection robot body 1 is rotatably connected to a cylindrical protective cover 4 through a damping bearing. The outer side of the cylindrical protective cover 4 is fixedly sleeved with an annular plate 5, and one side of the annular plate 5 is fixedly provided with an equidistant axial A connecting rod 6 is fixedly connected to one end of the connecting rod 6 with an expansion mechanism 7, and a dislocation strength detection mechanism 8 is arranged inside the expansion mechanism 7. The expansion mechanism 7 can control the two groups of dislocation strength detection mechanisms 8 to extend and retract at the same time. When the dislocation strength detection mechanism 8 is needed to detect the dislocation strength of the dislocated part of the pipeline, the two groups of dislocation strength detection mechanisms 8 are controlled to expand outward at the same time by the expansion mechanism 7. When the two groups of dislocation strength detection mechanisms 8 both touch the inner wall of the pipeline, the two groups of dislocation strength detection mechanisms 8 can be used to measure the dislocation degree of the dislocated pipeline respectively with the non-dislocated pipeline where the pipeline detection robot body 1 is located as the center. When the pipeline is not dislocated, the values ​​detected by the two groups of dislocation strength detection mechanisms 8 are the same. When the pipeline is dislocated, the symmetrically arranged The difference between the values ​​detected by the two sets of dislocation strength detection mechanisms 8 divided by two is the dislocation distance of the pipeline. After the detection is completed, the two sets of dislocation strength detection mechanisms 8 are controlled to retract inward by the expansion mechanism 7, so that the dislocation strength detection mechanisms 8 can be stored and protected, and the dislocation strength detection mechanisms 8 can be prevented from being damaged. One end of the water pipe 3 that runs through the pipeline detection robot body 1 is rotatably connected to a rotary high-pressure flushing mechanism 9 through a bearing. A ratchet transmission mechanism 10 is provided on the outer side of the rotary high-pressure flushing mechanism 9. A linkage mechanism 11 is provided between the ratchet transmission mechanism 10 and the columnar protective cover 4. Water is supplied to the rotary high-pressure flushing mechanism 9 through the water pipe 3. The rotary high-pressure flushing mechanism 9 can spray water while rotating, so as to perform all-round flushing of the sludge at the dislocation of the pipeline. , it can prevent the sludge adhering to the inner wall of the pipeline from affecting the detection accuracy of the dislocation strength detection mechanism 8 on the dislocation strength of the pipeline. The ratchet transmission mechanism 10 uses its specific structure to ensure that the rotary high-pressure flushing mechanism 9 rotates normally to flush the pipeline dislocation without driving the linkage mechanism 11 and the columnar protective cover 4 to rotate. After the sludge at the pipeline dislocation is flushed by the rotary high-pressure flushing mechanism 9, the rotary high-pressure flushing mechanism 9 is controlled to rotate in the opposite direction. When the rotary high-pressure flushing mechanism 9 rotates in the opposite direction, the linkage mechanism 11 can be driven to rotate through the ratchet transmission mechanism 10, and the columnar protective cover 4 can be finally driven to rotate through the linkage mechanism 11. When the columnar protective cover 4 rotates, the expansion mechanism 7 and the dislocation strength detection mechanism 8 can be driven to rotate through the connecting rod 6.The dislocation strength detection mechanism 8 can perform all-round detection of the dislocation strength of the pipe at the dislocation position, so that the staff can formulate a repair plan according to the actual dislocation strength of the pipe;

[0043] The ratchet transmission mechanism 10 includes a rotating disk 1001 fixedly sleeved on the outside of the rotary high-pressure flushing mechanism 9 and a gear sleeve 1002 rotatably connected to the outside of the rotary high-pressure flushing mechanism 9 through a bearing. The rotating disk 1001 is provided with a mounting groove 1003, and a spring member 1004 is fixedly provided on one side of the inner cavity of the mounting groove 1003. One end of the spring member 1004 is fixedly connected to a clamping member 1005, and one end of the clamping member 1005 is rotatably connected to the mounting groove 1003 through a rotating shaft. A clamping tooth 1006 is fixedly provided axially equidistantly on the inner side of the gear sleeve 1002. Figure 7 For example, when the rotary high-pressure flushing mechanism 9 rotates normally to flush the misaligned part of the pipeline, the turntable 1001 rotates clockwise under the drive of the rotary high-pressure flushing mechanism 9. When the turntable 1001 rotates clockwise, it drives the clamping member 1005 to rotate clockwise. At this time, the clamping member 1005 will rotate a certain angle under the specific structure of the clamping teeth 1006 to press the spring member 1004. At this time, it will not drive the gear sleeve 1002 to rotate, and then will not drive the linkage mechanism 11 and the cylindrical protective cover 4 to rotate. On the contrary, when the rotary high-pressure flushing mechanism 9 is controlled to rotate in the opposite direction, When rotating, the rotary high-pressure flushing mechanism 9 drives the turntable 1001 to rotate counterclockwise. At this time, one end of the clamping piece 1005 is clamped on the clamping tooth 1006, which will drive the gear sleeve 1002 to rotate synchronously, and then drive the linkage mechanism 11 and the cylindrical protective cover 4 to rotate. When the cylindrical protective cover 4 rotates, it can drive the expansion mechanism 7 and the dislocation strength detection mechanism 8 to rotate through the connecting rod 6, so that the dislocation strength detection mechanism 8 can perform all-round detection of the dislocation strength of a circle of the pipe at the dislocation, which is convenient for the staff to formulate a repair plan according to the actual dislocation strength of the pipeline.

[0044] As a further embodiment of the above invention: the damping bearing connected between the cylindrical protective cover 4 and the pipeline inspection robot body 1 is a one-way damping bearing, as shown in the attached manual. Figure 7 For example, when the rotary high-pressure flushing mechanism 9 rotates normally to flush the misaligned part of the pipeline, the ratchet transmission mechanism 10 idles. The friction force of the ratchet transmission mechanism 10 when idling is less than the force required for the damping bearing to rotate, so that the ratchet transmission mechanism 10 will not drive the cylindrical protective cover 4 to rotate when idling.

[0045] As a further implementation scheme of the above invention: the expansion mechanism 7 includes an outer shell 701 fixedly installed at one end of the connecting rod 6 and a storage port 702 symmetrically arranged on the outside of the outer shell 701, a mounting column 703 and a rotating motor 704 are fixedly arranged inside the outer shell 701, and a gear plate 705 is rotatably connected to the outer side of one end of the mounting column 703 through a bearing, and an arc-shaped driving groove 706 is provided on the gear plate 705, and a driving gear 707 is fixedly connected to the end of the output shaft of the rotating motor 704, and the driving gear 707 is meshingly connected with the gear plate 705, and the driving gear 707 can be driven to rotate by the rotating motor 704, and the driving gear 707 can drive the gear plate 705 to rotate when the driving gear 707 rotates, and the gear plate 705 can be driven to rotate when the gear plate 705 rotates. When the gear plate 705 rotates, the arc-shaped driving groove 706 can drive the two sets of misalignment strength detection mechanisms 8 to extend and retract at the same time, and the misalignment strength detection mechanisms 8 need to be used. When the strength detection mechanism 8 performs misalignment strength detection on the misaligned part of the pipeline, the expansion mechanism 7 controls the two groups of misalignment strength detection mechanisms 8 to expand outward at the same time. When the two groups of misalignment strength detection mechanisms 8 both hit the inner wall of the pipeline, the two groups of misalignment strength detection mechanisms 8 can respectively measure the misalignment degree of the misaligned pipeline with the non-misaligned pipeline where the pipeline detection robot body 1 is located as the center. When the pipeline is not misaligned, the values ​​detected by the two groups of misalignment strength detection mechanisms 8 are the same. When the pipeline is misaligned, the difference between the values ​​detected by the two symmetrically arranged groups of misalignment strength detection mechanisms 8 divided by two is the misalignment distance of the pipeline. After the detection is completed, the expansion mechanism 7 controls the two groups of misalignment strength detection mechanisms 8 to shrink inward, so that the misalignment strength detection mechanisms 8 can be stored and protected, and the misalignment strength detection mechanisms 8 can be prevented from being damaged.

[0046] As a further implementation scheme of the above invention: the dislocation strength detection mechanism 8 includes a displacement sensor 801 movably interspersed in the receiving port 702, a guide assembly 802 is provided between the outer side of the displacement sensor 801 and the receiving port 702, a connecting column 803 is fixedly provided on the outer side of one end of the displacement sensor 801, a sealing cover plate 804 is fixedly provided on the end of the displacement sensor 801 away from the connecting column 803, and a pulley assembly 805 is fixedly provided on the outer side of the sealing cover plate 804. When the ends of the two groups of dislocation strength detection mechanisms 8 both touch the inner wall of the pipeline, the displacement sensors 801 on the two groups of dislocation strength detection mechanisms 8 can respectively measure the dislocation degree of the dislocated pipeline with the non-dislocated pipeline where the pipeline detection robot body 1 is located as the center. When the pipeline is not dislocated, the values ​​detected by the two groups of displacement sensors 801 are the same. When the pipeline is dislocated, the difference between the values ​​detected by the two symmetrically arranged displacement sensors 801 divided by two is the dislocation distance of the pipeline. The pulley assembly 805 is provided so that the dislocation strength detection mechanism 8 can be better rotated along the inner wall of the pipeline for all-round detection.

[0047] As a further implementation scheme of the above invention: the guide assembly 802 is composed of a guide slide opened on the inner side of the storage opening 702 and a guide protrusion symmetrically arranged on the outer side of the displacement sensor 801, and the guide protrusion is passed through the guide slide. The displacement sensor 801 can be guided and limited by the guide protrusion and the guide slide, so that the displacement sensor 801 can move smoothly.

[0048] As a further implementation scheme of the above invention: one end of the connecting column 803 is inserted into the arc-shaped driving groove 706, and the size of the sealing cover plate 804 matches the size of the end of the storage port 702. The end of the storage port 702 can be sealed by the sealing cover plate 804, so as to better protect the misalignment strength detection mechanism 8 after storage.

[0049] As a further implementation scheme of the above invention: the rotary high-pressure flushing mechanism 9 includes a hollow pipe 901 rotatably connected to one end of the water pipe 3 through a bearing and a drive motor 902 fixedly installed at one end of the pipeline inspection robot body 1, a driving gear 903 is fixedly provided at the end of the output shaft of the drive motor 902, a driven gear 904 is fixedly sleeved on the outer side of the hollow pipe 901, one end of the hollow pipe 901 passes through the cylindrical protective cover 4 and is connected to a hollow water collecting pan 905, the outer side of the hollow water collecting pan 905 is connected to a high-pressure nozzle 906 through a branch pipe, and the high-pressure nozzle 906 is connected to the water pipe 3 through the water pipe 3. While supplying water to the rotary high-pressure flushing mechanism 9, turn on the drive motor 902. The drive motor 902 can drive the driven gear 904 to rotate through the driving gear 903. The driven gear 904 can drive the hollow pipe fitting 901 to rotate. When the hollow pipe fitting 901 rotates, it can drive the hollow water collecting plate 905 and the high-pressure nozzle 906 to rotate. It can rotate and spray water at the same time, and can perform all-round flushing of the silt at the misaligned part of the pipe, so as to avoid the silt adhering to the inner wall of the pipe and affecting the detection accuracy of the misalignment strength of the misaligned part of the pipe by the misalignment strength detection mechanism 8.

[0050] As a further implementation scheme of the above invention: a through opening is opened at one end of the cylindrical protective cover 4, and the hollow pipe 901 movably passes through the through opening and is connected with the hollow water collecting tray 905, which can prevent the hollow pipe 901 from affecting the cylindrical protective cover 4 when rotating.

[0051] As a further implementation scheme of the above invention: the pipeline inspection robot body 1 and the inspection camera 2 are connected to the external terminal, and the external terminal is connected to an alarm. During the crawling process of the pipeline inspection robot body 1, the inspection camera 2 can be used to photograph and inspect the inside of the pipeline, and the photographed images are transmitted to the external terminal. When the inspection camera 2 detects that the pipeline is misaligned, the external terminal controls the external alarm to turn on the alarm to remind workers to carry out timely maintenance.

[0052] As a further implementation scheme of the above invention: the linkage mechanism 11 includes a connecting column 1101 fixedly arranged at one end of the pipeline inspection robot body 1, one end of the connecting column 1101 is rotatably connected to a linkage gear 1102 through a bearing, and the linkage gear 1102 is meshed and connected with the gear sleeve 1002, and the outer side of the linkage gear 1102 is meshed and connected with a ring gear 1103, and the ring gear 1103 is fixedly installed on the inner side of the cylindrical protective cover 4, as shown in the attached manual Figure 7 For example, when the rotary high-pressure flushing mechanism 9 rotates normally to flush the misaligned part of the pipeline, the turntable 1001 rotates clockwise under the drive of the rotary high-pressure flushing mechanism 9. When the turntable 1001 rotates clockwise, it drives the clamping member 1005 to rotate clockwise. At this time, the clamping member 1005 will rotate a certain angle under the specific structure of the clamping teeth 1006 to press the spring member 1004. At this time, it will not drive the gear sleeve 1002 to rotate, and then will not drive the linkage mechanism 11 and the cylindrical protective cover 4 to rotate. On the contrary, when the rotary high-pressure flushing mechanism 9 is controlled to rotate in the opposite direction, the rotary high-pressure flushing mechanism 9 drives the turntable 1001 to rotate clockwise. 1 rotates counterclockwise, at this time, one end of the clamping piece 1005 is clamped on the clamping tooth 1006 to drive the gear sleeve 1002 to rotate synchronously, and the gear sleeve 1002 can drive the linkage gear 1102 to rotate when it rotates synchronously. When the linkage gear 1102 rotates, it can drive the cylindrical protective cover 4 to rotate through the ring gear 1103. When the cylindrical protective cover 4 rotates, it can drive the expansion mechanism 7 and the misalignment strength detection mechanism 8 to rotate through the connecting rod 6, so that the misalignment strength detection mechanism 8 can perform all-round detection of the misalignment strength of the pipeline at the misaligned position, so that the staff can formulate a repair plan according to the actual misalignment strength of the pipeline.

[0053] During the specific implementation: the pipeline inspection robot body 1 is placed in the pipeline to be inspected, and the staff controls the pipeline inspection robot body 1 to crawl in the pipeline from the outside. During the crawling process of the pipeline inspection robot body 1, the detection camera 2 can be used to shoot and inspect the inside of the pipeline, and the photographed picture is transmitted to the external terminal. When the detection camera 2 detects that the pipeline is misaligned, the external terminal controls the external alarm to turn on and give an alarm reminder. While supplying water to the rotary high-pressure flushing mechanism 9 through the water pipe 3, the drive motor 902 is turned on. The drive motor 902 drives the driven gear 904 to rotate through the active gear 903. The driven gear 904 can drive the hollow pipe fitting 901 to rotate. When the hollow pipe fitting 901 rotates, it can drive the hollow water collecting plate 905 and the high-pressure nozzle 906 to rotate, and it can spray water while rotating, so as to perform all-round flushing of the sludge at the misaligned part of the pipeline;

[0054] After the sludge at the dislocation of the pipeline is flushed in all directions, the rotating motor 704 is controlled to rotate. When the rotating motor 704 rotates, it can drive the driving gear 707 to rotate. When the driving gear 707 rotates, it can drive the gear plate 705 to rotate. When the gear plate 705 rotates, it can drive the two sets of dislocation strength detection mechanisms 8 to expand outward at the same time through the arc-shaped driving groove 706. When the two sets of dislocation strength detection mechanisms 8 both hit the inner wall of the pipeline, the two sets of dislocation strength detection mechanisms 8 can respectively take the pipeline without dislocation where the pipeline detection robot body 1 is located as the center to detect the dislocation of the pipeline. The degree of misalignment is measured. When the pipeline is not misaligned, the values ​​detected by the two groups of misalignment strength detection mechanisms 8 are the same. When the pipeline is misaligned, the difference between the values ​​detected by the two symmetrically arranged groups of misalignment strength detection mechanisms 8 divided by two is the misalignment distance of the pipeline. After the detection of the misaligned part of the pipeline is completed, the rotary motor 704 is controlled to rotate in the opposite direction. When the rotary motor 704 rotates in the opposite direction, the two groups of misalignment strength detection mechanisms 8 can be controlled to shrink inward at the same time through the arc-shaped driving groove 706, so that the misalignment strength detection mechanism 8 can be stored and protected, and the misalignment strength detection mechanism 8 can be prevented from being damaged.

[0055] Instructions attached Figure 7 For example, when the rotary high-pressure flushing mechanism 9 rotates normally to flush the misaligned part of the pipeline, the turntable 1001 rotates clockwise under the drive of the rotary high-pressure flushing mechanism 9. When the turntable 1001 rotates clockwise, it drives the clamping piece 1005 to rotate clockwise. At this time, the clamping piece 1005 will rotate a certain angle under the specific structure of the clamping tooth 1006 to press the spring piece 1004. At this time, it will not drive the gear sleeve 1002 to rotate, and then will not drive the linkage mechanism 11 and the cylindrical protective cover 4 to rotate. On the contrary, when the rotary high-pressure flushing mechanism 9 is controlled to rotate in the opposite direction, the rotary high-pressure flushing mechanism 9 will rotate in the opposite direction. The washing mechanism 9 drives the turntable 1001 to rotate counterclockwise. At this time, one end of the clamping piece 1005 is clamped on the clamping tooth 1006 to drive the gear sleeve 1002 to rotate synchronously. When the gear sleeve 1002 rotates synchronously, it can drive the linkage gear 1102 to rotate. When the linkage gear 1102 rotates, it can drive the cylindrical protective cover 4 to rotate through the annular gear 1103. When the cylindrical protective cover 4 rotates, it can drive the expansion mechanism 7 and the dislocation strength detection mechanism 8 to rotate through the connecting rod 6.
