[0029] The concept, specific structure, and technical effects of the present utility model will be clearly and completely described below in conjunction with embodiments and the accompanying drawings to fully understand the purpose, features, and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model. In addition, all connection / linkage relationships involved in the patent do not simply refer to the direct connection of components, but refer to the composition of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. The various technical features in the creation of the present utility model can be interactively combined without conflicting with each other.

[0030] Referring to Figures 1 to 3 , a pipeline detector provided by an example of the present utility model includes a detection device 1, a battery 2, an operating rod 3, and a support rod 4.

[0031] Functionally, the detection device 1 is used to detect the internal structure of the pipeline, the battery 2 is used to provide electrical energy for the detection device 1, the operating rod 3 is used to extend the detection device 1 into the pipeline, and the support rod 4 is used to support the detection device 1.

[0032] Structurally, the detection device 1 includes a bracket 11, a periscope assembly 12, and a ranging assembly 13. The periscope assembly 12 is arranged on the bracket 11, the ranging assembly 13 is arranged on the periscope assembly 12. The periscope assembly 12 is used to take pictures of the internal image of the pipeline, and the ranging assembly 13 is used to measure the distance between the periscope assembly 12 and the pipeline opening. When the periscope assembly 12 takes pictures of defects inside the pipeline, the location of the defects can be determined according to the data measured by the ranging assembly 13, so as to facilitate the precise repair of the pipeline by the staff.

[0033] Furthermore, the battery 2 is arranged on the bracket 11, the battery 2 is electrically connected to the detection device 1. One end of the operating rod 3 is connected to the bracket 11, the support rod 4 is movably arranged on the operating rod 3, the support rod 4 is arranged parallel to the operating rod 3, and a buffer assembly 5 is arranged at one end of the support rod 4. The buffer assembly 5 is used to buffer the impact caused when the detection device 1 reaches the bottom of the pipeline instantaneously, so as to reduce the vibration received by the components inside the device and improve the service life of the device.

[0034] It should be noted that a buffer assembly 5 is arranged at one end of the support rod 4, and the buffer assembly 5 is in direct contact with the bottom of the pipeline, which can quickly buffer the impact caused when the detection device 1 reaches the bottom of the pipeline instantaneously, avoiding the direct contact between the support rod 4 and the bottom of the pipeline, thus preventing the support rod 4 from deforming.

[0035] In some preferred embodiments, the buffer assembly 5 includes a slide rod 51 and a spring 52 sleeved on the outer periphery of the slide rod 51. The support rod 4 is provided with an inner hole, and the slide rod 51 is slidably engaged with the inner hole. One end of the slide rod 51 is provided with a first boss 511, and one end of the support rod 4 is provided with a second boss 41. The first boss 511 and the second boss 41 are respectively used to resist both ends of the spring 52. A limiting groove 42 is provided on one side of the support rod 4, and a limiting bolt 512 is connected to one side of the support rod 4. The slide rod 51 drives the limiting bolt 512 to move in the limiting groove 42, thereby restricting the movement range of the slide rod 51 and preventing the slide rod 51 from detaching from the support rod 4.

[0036] It can be understood that when the device reaches the bottom, one end of the slide rod 51 abuts against the bottom of the pipeline. At the same time, under the action of gravity and external force of the whole device, the slide rod 51 slides along the inner hole of the support rod 4, and the spring 52 is compressed. At this time, under the action of its own elastic force, the spring 52 prevents the slide rod 51 from continuing to slide, thereby improving the shock absorption effect of the device.

[0037] Furthermore, the buffer assembly 5 further includes a rubber pad 53. The rubber pad 53 is arranged at one end of the slide rod 51 away from the support rod 4. When the device reaches the bottom, the rubber pad 53 at one end of the slide rod 51 abuts against the bottom of the pipeline, thereby realizing double buffering and greatly improving the shock absorption effect of the device.

[0038] Specifically, the rubber pad 53 is a spherical structure, which is convenient for adapting to different terrains with different shapes at the bottom of different pipelines.

[0039] In some preferred embodiments, the periscope assembly 12 includes a housing 121, a camera 122, a lighting lamp 123, a movement 124, a main board 125 and a driving member 126. The housing 121 is rotatably connected to the bracket 11 through a rotating shaft 127. The distance measuring assembly 13, the camera 122 and the lighting lamp 123 are all arranged on the housing 121. The movement 124, the main board 125 and the driving member 126 are all arranged inside the housing 121. The driving member 126 is used to drive the housing 121 to rotate, and further drive the camera 122 to rotate at different angles, thereby being able to capture images of different positions inside the pipeline and improving the detection range of the camera 122.

[0040] Specifically, the camera 122 and the lighting lamp 123 are located on the same side, and the number of the lighting lamps 123 is multiple. The multiple lighting lamps 123 are distributed around the camera 122, thereby being able to illuminate the inside of the pipeline, making the images captured by the camera 122 clearly visible and improving the shooting quality of the camera 122.

[0041] More specifically, the driving member 126 includes a motor. The output shaft of the motor is connected with a first gear 1261. A second gear 1271 is arranged on the rotating shaft 127. The first gear 1261 meshes with the second gear 1271. The motor drives the first gear 1261 to rotate. The first gear 1261 drives the second gear 1271 to rotate. The second gear 1271 drives the rotating shaft 127 to rotate. The rotating shaft 127 drives the housing 121 to rotate. Thus, the overall rotation of the camera 122 can be realized, and the rotation accuracy is high, the structure is simple, and it is easy to implement.

[0042] In some preferred embodiments, a light shield 128 is arranged outside the camera 122. The light shield 128 is used to block the light irradiated by the lighting lamp 123 onto the camera 122. Thus, it can prevent the light from directly irradiating onto the camera 122, reduce the interference of the light on the camera 122, and improve the image quality of the captured image.

[0043] Furthermore, a defogger 129 is also arranged on the camera 122. The defogger 129 is used to eliminate the fog formed on the lens of the camera 122. Thus, it can avoid the lens of the camera 122 from fogging and affecting the shooting.

[0044] In some preferred embodiments, the operating rod 3 and the support rod 4 are connected through a connecting block 6. The connecting block 6 is provided with a counterbore 61 for accommodating the end of the operating rod 3. A first locking member 62 is arranged on one side of the counterbore 61. A hoop 63 is arranged on one side of the connecting block 6. The hoop 63 is sleeved on the outer periphery of the support rod 4. A second locking member 64 is arranged on one side of the hoop 63. The bottom of the connecting block 6 is connected to the bracket 11 through a connecting seat 65. After one end of the operating rod 3 enters the counterbore 61, the operating rod 3 is locked on the connecting block 6 through the first locking member 62, which is convenient for the installation of the operating rod 3. After the hoop 63 is sleeved on the outer periphery of the support rod 4, the tightness of the hoop 63 can be adjusted through the second locking member 64. Thus, the support rod 4 can be locked or loosened. Furthermore, the position of the detection device 1 on the support rod 4 can be adjusted.

[0045] Specifically, when detecting different pipelines, first adjust the tightness of the hoop 63 through the second locking member 64 to loosen the support rod 4, and then slide the support rod 4 to adjust the position of the detection device 1 on the support rod 4. Thus, the position of the detection device 1 at the center of the pipeline can be adjusted, which is convenient for detection.

[0046] More specifically, the first locking member 62 is a self-locking knob plunger. An installation hole is communicated with one side of the counterbore 61. The self-locking knob plunger is installed in the installation hole. By operating the self-locking knob plunger, the operating rod 3 entering the counterbore 61 can be locked or loosened. Thus, the installation convenience is improved, and the installation efficiency is increased.

[0047] The second locking member 64 is a hand-tightening bolt. The hoop 63 is provided with a through hole and a threaded hole. The hand-tightening bolt passes through the through hole and is screwed with the threaded hole to facilitate adjusting the tightness of the hoop 63.

[0048] In some preferred embodiments, a battery compartment 21 is provided on the bracket 11. A compartment cover 22 is provided on the top of the battery compartment 21. The compartment cover 22 is provided with an opening 221. A battery case 23 is provided on the top of the compartment cover 22. The bottom of the battery case 23 seals the opening 221 of the compartment cover 22. One end of the battery 2 is installed in the battery compartment 21, and the other end of the battery 2 extends out of the opening 221. The battery case 23 accommodates the part of the battery 2 that extends out of the opening 221. Thus, the battery 2 can be in a closed space to avoid being damaged by external impact.

[0049] Further, a plurality of outwardly extending arc-shaped flanges 231 are provided at the bottom of the battery compartment 21. A plurality of arc-shaped grooves 222 are provided on the top of the compartment cover 22. The plurality of arc-shaped grooves 222 are circumferentially and annularly arranged along the circumference of the opening 221. The arc-shaped flanges 231 are placed in the spaces between adjacent two arc-shaped grooves 222. The plurality of arc-shaped flanges 231 can be screwed into the plurality of arc-shaped grooves 222. Thus, it is convenient to disassemble and assemble the battery case 23.

[0050] Further, a sealing ring is provided between the bottom of the battery case 23 and the compartment cover 22. Thus, the sealing performance between the battery case 23 and the compartment cover 22 is improved to prevent external dust or water from entering the battery compartment 21 and ensure the normal use of the battery 2.

[0051] In some preferred embodiments, a wire conduit 211 is communicated with the bottom of the battery compartment 21. A wire threading shaft 120 is provided on one side of the housing 121. A wire threading hole 1201 is provided in the wire threading shaft 120. The wire conduit 211 is connected to the wire threading shaft 120. One end of the wire threading hole 1201 is communicated with the wire conduit 211, and the other end of the wire threading hole 1201 is communicated with the housing 121. The wire connecting the battery 2 passes through the wire conduit 211 and the wire threading hole 1201 in sequence and enters the housing 121, and is connected to the components in the housing 121. Thus, the wire can be prevented from being exposed and the safety performance can be improved.

[0052] Specifically, the wire conduit 211 is an aluminum alloy tube. The aluminum alloy tube has strong corrosion resistance and is not easy to age. Thus, the service life of the equipment is improved.
