Description

Technical Field

[0001] This utility model relates to the field of laser ranging equipment technology, and in particular to an angle adjustment device for laser ranging equipment in a confined space. Background Technology

[0002] Urban underground lifelines refer to various critical facilities and systems located underground during urban construction and operation. They are the foundation for the normal operation of the city and cover multiple aspects such as water supply, power supply, gas supply, communication, drainage, heating, and transportation. In order to ensure the normal operation of urban underground lifelines, maintenance personnel regularly use laser ranging equipment to collect data on urban underground lifelines. Laser ranging equipment integrates 3D LiDAR, wide-angle camera, laser rangefinder, and communication control modules. Through multi-sensor integration mode and corresponding data fusion and image processing technology, it works with a dedicated client to complete the collection of data in the limited space of urban underground lifelines.

[0003] However, in existing technologies, laser ranging devices require the acquisition end to be inserted into a well or underground, and then the laser ranging device must be manually rotated to make the acquisition end rotate 360° underground to obtain underground data. During the acquisition process, the operator needs to hold the laser ranging device by hand. Since the rotation of the acquisition end is not stable during the manual rotation of the laser ranging device, the acquired data has a large error and low data acquisition accuracy, which is a defect. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem in the existing technology that requires operators to hold the laser rangefinder during the data acquisition process. Because the rotation of the acquisition end is unstable during the manual rotation of the laser rangefinder, the acquired data has large errors and low data acquisition accuracy. Therefore, this invention proposes an angle adjustment device for a laser rangefinder in a confined space.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an angle adjustment device for a confined space laser ranging equipment, comprising a power module body, a gimbal motor fixedly connected to one side surface of the power module body, a support sleeve fixedly connected to the output end of the gimbal motor, an adjustment rod embedded inside the support sleeve, a data acquisition end body fixedly connected to one end of the adjustment rod, multiple slots equally spaced on the outer surface of the adjustment rod, an L-shaped support frame fixedly connected to the outer surface of the support sleeve, a spring fixedly connected to one side surface of the L-shaped support frame, an L-shaped clip fixedly connected to one end of the spring, and one end of the L-shaped clip embedded in one of the slots.

[0006] Furthermore, the lower surface of the power module body is rotatably connected to two support rods via a pivot. The two support rods are arranged diagonally, and telescopic rods are embedded inside the two support rods.

[0007] Furthermore, a connecting block is fixedly connected to one end of each of the two telescopic rods, and a rubber pad is fixedly connected to the lower surface of each of the two connecting blocks.

[0008] Furthermore, a limiting groove is formed on the outer surface of both support rods, and a limiting slider is embedded inside the two limiting grooves. One side surface of the two limiting sliders is fixedly connected to one end of the telescopic rod.

[0009] Furthermore, an anti-slip pad is fixedly connected to one side surface of the L-shaped clip, and multiple grooves are equidistantly formed on one side surface of the anti-slip pad.

[0010] Furthermore, a positioning groove is provided on the outer surface of the adjusting rod, and a positioning block is embedded in the inner wall surface of the positioning groove. One side surface of the positioning block is fixedly connected to the inner wall surface of the support sleeve.

[0011] Furthermore, two support blocks are fixedly connected to the outer surface of the power module body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when it is necessary to collect data from a well chamber or underground space, the L-shaped clip is pulled outwards to compress the spring. After the spring is stressed, it compresses its stroke, and the L-shaped clip disengages from the slot. Then, the adjusting rod is pulled down and adjusted to a suitable position before releasing the L-shaped clip. The L-shaped clip is then pushed into the corresponding slot by the spring, fixing the support sleeve and the adjusting rod. Then, the main body of the power module is held in hand, and the main body of the acquisition end is inserted into the well chamber or underground. The gimbal motor drives the main body of the acquisition end to rotate through the support sleeve and the adjusting rod. The rotation angle of the main body of the acquisition end is adjusted at a uniform speed to avoid uneven speed or shaking during the rotation of the main body of the acquisition end, which would lead to low data acquisition accuracy. This ensures the accuracy of data acquisition and is applicable to well chambers or underground spaces of different specifications, with a wide range of applications.

[0014] 2. In this utility model, two support rods are rotated 180° during use. Two support blocks limit the rotation angle of the two support rods. Two connecting blocks pull the two telescopic rods. Then, the two connecting blocks are placed on the wellhead or the ground. The two telescopic rods and two support rods provide support for the main body of the power module, eliminating the need for operators to hold the device for extended periods and effectively improving stability during measurement. The two support rods are diagonally distributed to ensure the center of gravity and prevent the main body of the power module from tilting. Rubber pads prevent the connecting blocks from rubbing against the ground or wellhead, ensuring the service life of the components. Two limit sliders limit the stroke of the telescopic rods through limit grooves, preventing the telescopic rods from detaching from the support rods. The anti-slip pads on the outer surface of the L-shaped clips evenly increase friction through multiple grooves, improving the user experience. The positioning block and positioning groove cooperate to prevent the adjusting rod from rotating relative to the support sleeve, ensuring the stability of the equipment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, the present invention provides the following technical solution: an angle adjustment device for a laser ranging device in a confined space, wherein a gimbal motor 2 is fixedly connected to one side surface of the power module body 1, a support sleeve 3 is fixedly connected to the output end of the gimbal motor 2, an adjustment rod 7 is embedded inside the support sleeve 3, one end of the adjustment rod 7 is fixedly connected to the acquisition end body 4, a plurality of slots 8 are equidistantly opened on the outer surface of the adjustment rod 7, an L-shaped support frame 9 is fixedly connected to the outer surface of the support sleeve 3, a spring 10 is fixedly connected to one side surface of the L-shaped support frame 9, an L-shaped clip 11 is fixedly connected to one end of the spring 10, and one end of the L-shaped clip 11 is embedded in the interior of one of the slots 8.

[0023] In this embodiment, when data needs to be collected from a well chamber or underground space, the L-shaped clip 11 is pulled outwards, causing it to compress the spring 10. The spring 10 then compresses its stroke, disengaging the L-shaped clip 11 from the slot 8. Then, the adjusting rod 7 is pulled down and adjusted to a suitable position before releasing the L-shaped clip 11. The L-shaped clip 11, pushed by the spring 10, then engages with the corresponding slot 8. The support sleeve 3 is then fixed to the adjusting rod 7. The power module body 1 is held in hand, and the acquisition end body 4 is inserted into the well chamber or underground. The gimbal motor 2 drives the acquisition end body 4 to rotate via the support sleeve 3 and the adjusting rod 7, uniformly adjusting the rotation angle of the acquisition end body 4 to avoid uneven speed or wobbling during rotation, which could lead to low data accuracy and ensure data acquisition accuracy. This method is applicable to well chambers or underground spaces of different specifications and has a wide range of applications.

[0024] Example 2

[0025] like Figure 1-4 As shown, the lower surface of the power module body 1 is rotatably connected to two support rods 5 via a rotating shaft. The two support rods 5 are arranged diagonally. Telescopic rods 16 are embedded inside the two support rods 5. One end of each telescopic rod 16 is fixedly connected to a connecting block 19. The lower surface of each connecting block 19 is fixedly connected to a rubber pad 20. The outer surface of each support rod 5 is provided with a limiting groove 17. The inner surface of each limiting groove 17 is provided with a limiting slider 18. One side surface of each limiting slider 18 is fixedly connected to one end of the telescopic rod 16. One side surface of the L-shaped clip 11 is fixedly connected to an anti-slip pad 12. One side surface of the anti-slip pad 12 is provided with multiple grooves 13 at equal intervals. The outer surface of the adjusting rod 7 is provided with a positioning groove 14. The inner wall surface of the positioning groove 14 is provided with a positioning block 15. One side surface of the positioning block 15 is fixedly connected to the inner wall surface of the support sleeve 3. The outer surface of the power module body 1 is fixedly connected to two support blocks 6.

[0026] In this embodiment, during use, the two support rods 5 are rotated 180°, and the two support blocks 6 limit the rotation angle of the two support rods 5. The two telescopic rods 16 are pulled by the two connecting blocks 19, and then the two connecting blocks 19 are placed on the wellhead or the ground. The two telescopic rods 16 and the two support rods 5 provide support for the power module body 1, eliminating the need for the operator to hold it for a long time, effectively improving the stability during measurement. The two support rods 5 are diagonally distributed to ensure the center of gravity and prevent the power module body 1 from tilting. The rubber pads 20 prevent the connecting blocks 19 from rubbing against the ground or wellhead, ensuring the service life of the components. The two limit sliders 18 limit the stroke of the telescopic rods 16 through the limit grooves 17 to prevent the telescopic rods 16 from detaching from the support rods 5. The anti-slip pads 12 on the outer surface of the L-shaped clip 11 evenly increase the friction through multiple grooves 13, improving the user experience. The positioning block 15 and the positioning groove 14 cooperate to prevent the adjusting rod 7 from rotating relative to the support sleeve 3, ensuring the stability of the equipment.

[0027] Working principle: such as Figure 1-4 As shown, when data needs to be collected from a well chamber or underground space, the L-shaped clip 11 is pulled outwards, causing it to compress the spring 10. The spring 10 compresses its stroke under pressure, disengaging the L-shaped clip 11 from the slot 8. Then, the adjusting rod 7 is pulled down and adjusted to a suitable position before releasing the L-shaped clip 11. The L-shaped clip 11, pushed by the spring 10, then engages with the corresponding slot 8. The support sleeve 3 is then fixed to the adjusting rod 7. The power module body 1 is held in hand, and the acquisition end body 4 is inserted into the well chamber or underground. The gimbal motor 2 drives the acquisition end body 4 to rotate via the support sleeve 3 and the adjusting rod 7. The rotation angle of the acquisition end body 4 is adjusted uniformly to avoid uneven speed or shaking during rotation, which could lead to low data accuracy and ensure data acquisition accuracy. This method is applicable to well chambers or underground spaces of different specifications, has a wide range of applications, and can be used at 180 degrees. The two support rods 5 are rotated, and the two support blocks 6 limit the rotation angle of the two support rods 5. The two telescopic rods 16 are pulled by the two connecting blocks 19. Then the two connecting blocks 19 are placed on the wellhead or the ground. The two telescopic rods 16 and the two support rods 5 provide support for the power module body 1. The operator does not need to hold the power module body 1 for a long time, which effectively improves the stability during measurement. The two support rods 5 are diagonally distributed to prevent the power module body 1 from tilting. The rubber pad 20 prevents the connecting blocks 19 from rubbing against the ground or wellhead. The two limit sliders 18 limit the stroke of the telescopic rods 16 through the limit grooves 17 to prevent the telescopic rods 16 from disengaging from the support rods 5. The anti-slip pads 12 on the outer surface of the L-shaped clip 11 increase the friction evenly through multiple grooves 13. The positioning block 15 and the positioning groove 14 cooperate to prevent the adjusting rod 7 from rotating relative to the support sleeve 3.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
