Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, specifically a periscope for pipeline maintenance surveying. Background Technology

[0002] In the process of inspecting, maintaining, and surveying municipal pipelines, electronic periscopes are often used to observe the internal conditions of the pipelines. Most existing electronic periscopes are used with telescopic rods. After adjusting the telescopic rod to the required length, the electronic periscope is lowered into the inspection well. By rotating the electronic periscope with the telescopic rod, the camera orientation of the electronic periscope can be adjusted. The accompanying electronic display equipment can then be used to observe the images inside the pipeline. The operation is relatively simple, but holding the periscope for a long time can cause fatigue, and hand tremors can cause the images captured by the electronic periscope to shake, which can affect the observation effect on the internal conditions of the pipeline.

[0003] A search revealed that patent CN221124988U discloses a periscope for pipeline inspection. This periscope, comprising a placement plate, guide rod, mounting plate, motor, screw, moving plate, control components, buffer components, power supply, placement rod, periscope body, lighting, bracket, and pad, allows for inspection of different locations on a pipeline. The device is placed beside the pipeline, and the device is moved to align the periscope body with the top of the pipeline. Pressing a button powers the motor, which in turn rotates the screw. The screw then moves the moving plate, which in turn moves the placement rod, which in turn moves the periscope body. This invention allows for highly precise adjustment of the periscope body, improving the accuracy of the inspection location.

[0004] While the above solution utilizes a transmission mechanism consisting of a motor and a screw to achieve height adjustment of the periscope body, eliminating the need for the operator to hold the periscope for extended periods and improving stability during periscope imaging, it is inconvenient to adjust the orientation of the periscope body. When the orientation of the periscope body needs to be adjusted, the position of the placement plate must be adjusted at the top of the pipe, which is relatively cumbersome. Furthermore, the height adjustment of the periscope in this solution is limited by the length of the screw, requiring the use of a longer screw to ensure that the periscope can meet the inspection needs of most pipes, resulting in a larger device size and reduced portability, which requires improvement. Utility Model Content

[0005] The purpose of this invention is to provide a periscope for pipeline maintenance mapping to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A periscope for pipeline maintenance mapping includes a base, an electronic periscope, a boom, and several cylindrical racks.

The bottom end of the boom 18 is detachably connected to the top of the electronic periscope 21. The top ends of the boom 18 and the cylindrical racks 15 are each provided with a first threaded hole 16. The bottom ends of the cylindrical racks 15 are each fixedly provided with a screw 17. The first threaded hole 16 and the screw 17 are adapted to each other. The top of the base 1 is rotatably connected to a housing 6 through a turntable bearing. The base 1 and the housing 6 are respectively provided with a first through hole 5 and a second through hole 13 for passing through the cylindrical racks 15. A handle 7 is fixedly installed on the outer wall of the housing 6. A drive mechanism adapted to the cylindrical racks 15 is installed on the housing 6. Two guide blocks 14 are symmetrically fixedly connected in the second through hole 13. Guide grooves adapted to the guide blocks 14 are symmetrically provided on the outer walls of both sides of the cylindrical racks 15.

[0024] By adopting the above-described scheme, this utility model, in use, involves installing a cylindrical rack 15 through the housing 6 and the base 1, then installing a lifting rod 18 at the bottom end of the cylindrical rack 15, and installing an electronic periscope 21 at the bottom end of the lifting rod 18. The base 1 is then placed at the opening of the inspection well 24, and the driving mechanism is operated to move the cylindrical rack 15 downwards, thereby moving the periscope 21 downwards. By utilizing the cooperation of the first threaded hole 16 and the screw 17, the required number of cylindrical racks 15 can be spliced ​​together, allowing the electronic periscope 21 to descend to the desired depth. By rotating the housing 6 on the base 1 using the handle 7, the electronic periscope 21 can be rotated to adjust its orientation. The operation is simple and convenient, and since there is no need to hold the electronic periscope 21, the stability of the electronic periscope 21 when capturing images is ensured, resulting in good performance.

A worm 11 is rotatably mounted inside the housing 6. The worm 11 meshes with the worm gear 10. A handwheel 12 is fixedly connected to the top end of the worm 11 after it passes through the housing 6.

[0026] By rotating the worm gear 11 through the handwheel 12, the worm gear 11 and the worm wheel 10 can drive the rotating shaft 8 and the gear 9 to rotate. In turn, the gear 9 and the cylindrical rack 15 can drive the electronic periscope 21 to be raised and lowered, so that the electronic periscope 21 can be adjusted to the required height within the inspection well 24. The overall structure is simple, easy to operate, and highly stable.

A second hand-tightening bolt 20 is provided through the outer wall of the connecting sleeve 19, and a second threaded hole 23 adapted to the second hand-tightening bolt 20 is provided on the outer wall of the connecting seat 22.

[0028] The connection between the connecting seat 22 and the connecting sleeve 19 facilitates the quick assembly and disassembly of the boom 18 and the electronic periscope 21 by engaging the second hand-tightened bolt 20 and the second threaded hole 23.

By tightening the first hand-tightening bolt 4, the sliding rod 2 can be locked on the base 1. The operation is simple and convenient. When not in use, the sliding rod 2 can be completely retracted into the base 1 to reduce the space occupied by the device when not in use, making the device more portable.
