Description

Technical Field

[0001] The present application relates to the field of pipeline detection, and in particular to a high-definition digital self-cleaning pipeline detection camera. Background Art

[0002] The pipeline detector is an instrument used for internal and external inspection of pipelines. The inspection objects are usually various types of pipelines: such as municipal pipelines, petrochemical transportation pipelines, water supply pipes, industrial and mining infrastructure pipelines, industrial transportation and storage pipelines, built-in pipelines in living buildings, air conditioning exhaust ventilation pipes, etc.

[0003] In the related art, such as publication number CN109068093A, the pipeline detector includes a winding frame, a wheel, a camera, a cable and a high-definition control display, wherein the wheel is arranged at the bottom of the winding frame, the cable is wound on the winding frame, one end of the cable is electrically connected to the camera, and the other end of the cable is electrically connected to the high-definition control display. When performing pipeline detection work, the cable is gradually extended into the pipeline to make the camera move forward, thereby performing internal detection of the pipeline.

[0004] Regarding the above-mentioned related technologies, there is a defect that because the camera is made of metal as a whole, although the cable can be bent, the bending ability is weak, so the camera of the pipeline detector is not convenient to pass through the bend of the pipeline. Summary of the invention

[0005] In order to facilitate the camera to pass through the bends of the pipeline, the present application provides a high-definition digital self-cleaning pipeline detection camera.

[0006] The high-definition digital self-cleaning pipeline detection camera provided in this application adopts the following technical solution:

[0007] A high-definition digital self-cleaning pipeline detection camera, comprising:

[0008] Camera body;

[0009] A swing hose, one end of which is connected to the camera body and the other end of which is used to connect to the cable, and the swing hose is divided into a plurality of bending deformation zones around the axis direction;

[0010] The bending adjustment component is connected to the swing hose and is used to make the different bending deformation zones bend and deform as well as expand and contract along the swing hose.

[0011] By adopting the above technical solution, when the camera needs to pass through the bend of the pipeline, the bending adjustment component can be used to make the multiple bending deformation zones of the swing hose undergo different types and degrees of deformation. For example, when swinging to the left, the bending deformation zone on the left side bends and contracts, and the bending deformation zone on the right side bends and expands, so that the angle between the camera body and the cable can be changed, so that the camera body can pass through the bend of the pipeline more smoothly in an L-shaped bending posture.

[0012] Preferably, the bending adjustment component includes multiple bending adjustment ropes, one of the bending adjustment ropes is passed through the swing hose to form a bending adjustment channel, the bending adjustment channel is structured as a single channel opening, the bending adjustment channel is extended along the axis of the swing hose, one end of the bending adjustment channel away from the channel opening is located on the end of the swing hose away from the cable, one end of the bending adjustment rope is fixedly connected to the end of the bending adjustment channel away from the cable, and the other end slides through the channel opening of the bending adjustment channel.

[0013] By adopting the above technical solution, in the bending deformation zone where contraction deformation occurs, the bending adjustment rope gradually moves out of the bending adjustment channel, and in the bending deformation zone where expansion deformation occurs, the bending adjustment rope gradually moves into the bending adjustment channel. Therefore, even if the number of bending deformation zones is increased, the overall structure of the camera can be kept simple.

[0014] Preferably, the camera body is slidably passed through the inner side of the swing hose, and an adjusting steel rope is connected to the end of the camera body close to the cable, which is used to change the position of the camera body with the help of external power; a negative pressure sealing assembly is provided on the inner side of the swing hose, which is used to shrink the end of the swing hose away from the cable and tightly wrap the camera body by means of negative pressure.

[0015] By adopting the above technical solution, because there will be debris in the pipeline, when the camera body moves forward, the camera body can be pulled into the swing hose by adjusting the steel rope, and the swing hose can be wrapped tightly around the camera body through the negative pressure sealing assembly, thereby protecting the camera body.

[0016] Preferably, a cleaning protrusion is provided at the end face of the swing hose away from the cable, and a transition inner tube is coaxially fixedly connected to the end face of the swing hose close to the cable. A transition outer tube is rotatably sleeved on the outer side of the transition inner tube, and the transition outer tube is used to be fixedly connected to the end of the cable; a driven gear ring is coaxially connected to the end face of the transition inner tube away from the swing hose, and a rotating motor and a driving gear are provided on the inner side of the transition outer tube, the rotating motor is fixedly arranged, the driving gear is connected to the output shaft of the rotating motor, and the driving gear is meshed with the driven gear ring.

[0017] By adopting the above technical solution, after the camera body is retracted into the swing hose, the swing hose can be rotated through the cooperation between the driving gear and the driven gear ring, so that the cleaning protrusion can break up the impurities in the pipe, thereby allowing the camera body to smoothly pass through the bend of the pipe.

[0018] Preferably, the negative pressure sealing assembly is arranged in the adapter outer tube.

[0019] By adopting the above technical solution, the deformation of the swing hose will not be affected.

[0020] Preferably, the bending adjustment pull rope and the position adjustment steel rope are disconnected at the transition outer tube and are divided into a follow-rotating part and a stationary part, a pull rope rotation compatible part is arranged between the follow-rotating part and the stationary part of the bending adjustment pull rope, and a steel rope rotation compatible part is arranged between the follow-rotating part and the stationary part of the position adjustment steel rope.

[0021] By adopting the above technical solution, due to the setting of the pull rope rotation compatible part and the steel rope rotation compatible part, during the rotation of the swing hose, the bending pull rope and the position adjustment steel rope will not be twisted off, thereby maintaining the connection between the external driving source and the camera body and the swing hose.

[0022] Preferably, the rope rotation compatible part includes a rope slider, a rope rotating block and a rope reset part. The rope slider is slidably connected to the inner wall of the adapter outer tube. Multiple rope sliders are spliced ​​into a ring with the adjustment steel rope passing through the center. One rope slider is connected to the stationary part of the bending adjustment rope; the rope rotating block is slidably connected to the rope slider, and the rope rotating block moves around the center circle of multiple rope sliders. One rope rotating block is connected to the follow-up rotating part of the bending adjustment rope, and there is a distance between two adjacent rope rotating blocks; the rope reset part is connected to the rope slider, and is used to reset the multiple rope sliders to the same plane.

[0023] By adopting the above technical solution, during the rotation of the swinging hose, the pull rope can rotate around the center of multiple pull rope sliders, and the pull rope sliders will not rotate, so the multiple stationary parts will not be twisted together. When the swinging hose needs to be deformed, the pull rope slider can be moved to allow the following part to change the deformation of the swinging hose, and there is a distance between adjacent pull rope turning blocks. There is no need to completely align a pull rope turning block with a pull rope slider after each rotation to maintain the smoothness of the use of the bending adjustment component. In addition, the setting of the pull rope reset part can also improve the smoothness of the swinging hose to restore deformation.

[0024] Preferably, the steel rope rotation compatible part includes a mounting bracket, a steel rope slider and a steel rope rotating block. The mounting bracket is in the shape of a cross, and the gap of the mounting bracket is for the stationary part of the bending adjustment rope to rotate through; the steel rope slider is slidably connected to the center position of the mounting bracket, and the steel rope slider is connected to the stationary part of the positioning steel rope; the steel rope rotating block is rotationally connected to the steel rope slider, and the steel rope rotating block is connected to the follow-rotating part of the positioning steel rope.

[0025] By adopting the above technical solution, during the rotation of the swinging hose, the steel rope rotating block can rotate by itself, and the steel rope slider will not rotate, so the stationary part will not be broken. When the camera body needs to be moved, the pull rope slider can be moved to allow the adjustment steel rope to drive the camera body.

[0026] Preferably, the wall thickness of the swing hose at one end close to the cable is greater than the wall thickness at one end away from the cable.

[0027] By adopting the above technical solution, firstly, the connection between the camera body and the cable can have a certain rigidity to maintain the posture stability of the camera body; secondly, it can also make it easier for the end of the swing hose away from the cable to wrap the camera body tightly through negative pressure.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When the camera needs to pass through the bend of the pipeline, the bending adjustment component can be used to make the multiple bending deformation zones of the swing hose undergo different types and degrees of deformation. For example, when the swing hose is to be swung to the left, the bending deformation zone on the left side is bent and contracted, and the bending deformation zone on the right side is bent and expanded, so that the angle between the camera body and the cable can be changed, so that the camera body can pass through the bend of the pipeline more smoothly in an L-shaped bending posture;

[0030] 2. Because there may be debris in the pipeline, when the camera body moves forward, the camera body can be pulled into the swing hose by adjusting the steel rope, and the swing hose can be wrapped tightly around the camera body through the negative pressure sealing component, thereby protecting the camera body.

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The embodiment of the present application discloses a high-definition digital self-cleaning pipeline detection camera.

[0038] Reference Figures 1 to 3 The high-definition digital self-cleaning pipeline detection camera includes a camera body 1, a swing hose 2 and a bending component 3. The camera body 1 itself includes a front lens part, a rear vertical rotation part and a horizontal rotation part. The rear vertical rotation part allows the front lens part to rotate around the axis of the cable, and the horizontal rotation part allows the front lens to rotate around the axis of the vertical cable. The driving method adopts a combination of a motor and a gear transmission; one end of the swing hose 2 is connected to the camera body 1, and the other end is connected to the cable, and the swing hose 2 is divided into a plurality of bending deformation zones 21 around the axis direction; the bending component 3 is connected to the swing hose 2, which will cause different bending deformation zones 21 to bend and deform and expand and contract along the swing hose 2. For example, when swinging to the left, the bending deformation zone 21 on the left side is bent and contracted, and the bending deformation zone 21 on the right side is bent and expanded, so that the angle between the camera body 1 and the cable can be changed, so that the camera body 1 can pass through the bend of the pipeline more smoothly in an L-shaped bending posture.

[0039] Reference Figures 1 to 3In order to more freely adjust the relative posture between the camera body 1 and the cable, and to keep the overall structure of the camera simple, the bending adjustment component 3 includes a plurality of bending adjustment ropes 31. The bending adjustment ropes 31 are soft ropes. One bending adjustment rope 31 is passed through the swing hose 2 to form a bending adjustment channel 32. The bending adjustment channel 32 is structured as a single channel opening. The bending adjustment channel 32 is extended along the axis of the swing hose 2. The end of the bending adjustment channel 32 away from the channel opening is located on the end of the swing hose 2 away from the cable. One end of the bending adjustment rope 31 is fixedly connected to the end of the bending adjustment channel 32 away from the cable, and the other end slides through the channel opening of the bending adjustment channel 32. When the bending deformation zone 21 undergoes contraction deformation, the bending adjustment rope 31 gradually moves out of the bending adjustment channel 32. When the bending deformation zone 21 undergoes expansion deformation, the bending adjustment rope 31 gradually moves into the bending adjustment channel 32. Therefore, even if the number of bending deformation zones 21 is increased to improve the freedom of swinging, the simplicity of the overall structure of the camera can be maintained.

[0040] Reference Figure 1 and Figure 3 Considering that there will be impurities in the pipeline, in order to protect the camera body 1, the following settings are correspondingly arranged: the camera body 1 slides through the inner side of the swing hose 2, and the end of the camera body 1 close to the cable is connected to a positioning steel rope 4, and the other end of the positioning steel rope 4 is connected to an external power source, so that the external power can change the position of the camera body 1 with the help of the positioning steel rope 4. At the same time, a negative pressure sealing component 5 is arranged on the inner side of the swing hose 2, which can shrink the end of the swing hose 2 away from the cable and wrap the camera body 1 tightly by means of negative pressure, so that the swing hose 2 is sealed and connected to the camera body 1, thereby protecting the camera body 1 while maintaining the sealing performance.

[0041] Reference Figure 1 and Figure 3In order to break the impurities in the pipeline and allow the camera body 1 to smoothly pass through the bend of the pipeline, the following settings are correspondingly arranged: a cleaning protrusion 22 is arranged on the end face of the swing hose 2 away from the cable, and a switching inner tube 23 is coaxially fixedly connected to the end face of the swing hose 2 close to the cable. The switching inner tube 23 is made of a hard material, and a switching outer tube 24 is rotatably sleeved on the outer side of the switching inner tube 23. The switching outer tube 24 is fixedly connected to the end of the cable, and at the same time, a driven gear ring 25 is coaxially connected to the end face of the switching inner tube 23 away from the swing hose 2, and the inner side of the driven gear ring 25 is provided with a The bending adjustment rope 31 and the position adjustment steel rope 4 pass through, and a rotating motor 26 and a driving gear 27 are arranged on the inner side of the adapter outer tube 24. The rotating motor 26 is fixedly arranged, and the driving gear 27 is connected to the output shaft of the rotating motor 26. The driving gear 27 is meshed with the driven gear ring 25. After the camera body 1 is retracted to the swing hose 2, the swing hose 2 can be rotated through the cooperation between the driving gear 27 and the driven gear ring 25, so that the cleaning protrusion 22 can break the impurities in the pipeline, so that the camera body 1 can smoothly pass through the bend of the pipeline.

[0042] Reference Figure 1 and Figure 3 Considering that the camera body 1 and the swing hose 2 will rotate, in order to allow the bending adjustment rope 31 and the position adjustment steel rope 4 to be used normally, the bending adjustment rope 31 and the position adjustment steel rope 4 are disconnected at the connecting outer tube 24 and are divided into a rotating part and a stationary part, and a rope rotation compatible part 6 is provided between the rotating part and the stationary part of the bending adjustment rope 31, and a steel rope rotation compatible part 7 is provided between the rotating part and the stationary part of the position adjustment steel rope 4.

[0043] Reference Figure 3 and Figure 4 Specifically, the rope rotation compatible part 6 includes a rope slider 61, a rope rotating block 62 and a rope reset part 63. The rope slider 61 is slidably connected to the inner wall of the adapter outer tube 24. Multiple rope sliders 61 are spliced ​​into a ring shape, and the center is for the adjustment steel rope 4 to pass through. One rope slider 61 is connected to the stationary part of a bending rope 31; the rope rotating block 62 is slidably connected to the rope slider 61, and the rope rotating block 62 moves around the center circle of multiple rope sliders 61. One rope rotating block 62 is connected to the following rotating part of a bending rope 31, and there is a distance between two adjacent rope rotating blocks 62; the rope reset part 63 is connected to the rope slider 61, so that multiple rope sliders 61 can be reset to the same plane.

[0044] Reference Figure 3 and Figure 4The working principle is as follows: during the rotation of the swing hose 2, the rope pull block 62 can rotate around the center of multiple rope pull sliders 61, and the rope pull sliders 61 will not rotate, so the multiple stationary parts will not be twisted together. When the swing hose 2 needs to be deformed, the rope pull slider 61 can be moved to allow the following part to change the deformation of the swing hose 2, and there is a distance between adjacent rope pull blocks 62. There is no need to fully align a rope pull block 62 with a rope pull slider 61 after each rotation to maintain the smoothness of the use of the bending component 3. When the swing hose 2 needs to restore its deformation, the rope pull reset member 63 can be used to improve the smoothness of the swing hose 2 restoring its deformation.

[0045] Reference Figure 1 and Figure 4 The steel rope rotation compatible part 7 includes a mounting bracket 71, a steel rope slider 72 and a steel rope rotating block 73. The mounting bracket 71 is in the shape of a cross, and the gap of the mounting bracket 71 is for the stationary part of the bending rope 31 to rotate; the steel rope slider 72 is slidably connected to the center position of the mounting bracket 71, and the steel rope slider 72 is connected to the stationary part of the positioning steel rope 4; the steel rope rotating block 73 is rotatably connected to the steel rope slider 72, and the steel rope rotating block 73 is connected to the follow-rotating part of the positioning steel rope 4. In the process of rotation of the swing hose 2, the steel rope rotating block 73 can rotate by itself, and the steel rope slider 72 will not rotate, so the stationary part will not be broken. When the camera body 1 needs to be moved, the pull rope slider 61 can be moved to make the positioning steel rope 4 drive the camera body 1, thereby also realizing the function of the positioning steel rope 4 adapting to rotation and basic use.

[0046] Reference Figure 1 and Figure 3 In this embodiment, considering the simplicity of the structure, the negative pressure sealing component 5 is selected to be installed in the adapter outer tube 24. The negative pressure sealing component 5 is located on the side of the pull rope rotation compatible part 6 and the steel rope rotation compatible part 7 close to the cable. At the same time, a corresponding channel is set for the negative pressure sealing component 5 to allow the bending adjustment pull rope 31 and the adjustment steel rope 4 to pass through. In addition, in order to give the swing hose 2 a certain rigidity and to make it easier to wrap the camera body 1, the wall thickness of the swing hose 2 close to the cable end is greater than the wall thickness away from the cable end.

[0047] The implementation principle of a high-definition digital self-cleaning pipeline detection camera in an embodiment of the present application is as follows: when the camera needs to pass through a bend in the pipeline, the bending adjustment component 3 can be used to allow the multiple bending deformation zones 21 of the swing hose 2 to undergo deformation of different types and degrees. For example, when swinging to the left, the bending deformation zone 21 on the left side bends and contracts, and the bending deformation zone 21 on the right side bends and expands, so that the angle between the camera body 1 and the cable can be changed, so that the camera body 1 can pass through the bend of the pipeline more smoothly in an L-shaped bending posture.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
