Description

Technical Field

[0001] The utility model belongs to the technical field of power system infrastructure construction, and specifically relates to a positioning, installation and detection device for power system infrastructure construction. Background Art

[0002] Power system infrastructure construction refers to a series of engineering activities involved in the construction of new power facilities or the upgrading of existing facilities. These activities include but are not limited to the design, construction, installation and commissioning of transmission lines, substations, power plants and distribution networks. However, when excavating the foundation pit for pre-buried cables, when the depth inside the foundation pit changes, it often causes the depth of the buried cables to change, resulting in problems in cable construction, so the foundation pit needs to be inspected.

[0003] Foundation pit monitoring is an important part of foundation pit construction. It refers to various observations and analyses of the changes in the rock and soil properties of the foundation pit, the displacement of the supporting structure, and the changes in the surrounding environmental conditions during the foundation pit excavation and underground engineering construction. The monitoring results are fed back in a timely manner to predict the deformation and stable state development caused by further excavation and construction. According to the prediction, the degree of impact of the construction on the surrounding environment is determined to guide the design and construction and realize the so-called information construction. Most of the existing deep foundation pit monitoring uses a prism rod to fix the prism on the outside of the deep foundation pit to monitor the internal conditions of the foundation pit. Not only is positioning time-consuming, but it is also easy to make the installation position or movement position inaccurate, affecting the monitoring effect. Utility Model Content

DETAILED DESCRIPTION

The bottom of the component 8 is provided with connecting grooves 15 on both sides, and the detection component 8 is engaged with the two sides of the two sets of slide rails 7 through the connecting grooves 15; the bottom of the two sets of slide rails 7 is provided with a first observation port 13, and a second observation port 14 is provided on one side of the first observation port 13. The detection component 8 detects the depth and the angles on both sides of the bottom of the foundation pit through the second observation port 14 and the first observation port 13 respectively. At the same time, the width of the first observation port 13 is greater than the width of the second observation port 14. When the detection component 8 moves on the slide rail 7, it can obtain a larger observation angle through the first observation port 13. A scraper 10 is provided on one side of the movable body 1 near the second observation port 14. When the movable body 1 is moving, the scraper 10 will peel off the mud and stones that block the movement, so as to facilitate the smooth operation of the movable body 1. A baffle 6 is installed between the two sets of motor chambers 5. The baffle 6 and the connecting plate 4 ensure that the detection component 8 will not deviate from the predetermined track or position during the movement.

[0023] Tracks 2 are installed on both sides of the movable vehicle body 1 in a direction parallel to the connecting plate 4. Gears 12 are connected to both sides of the inner wall of the track 2, and a sealing cover 3 is installed on the side of the track 2 away from the movable vehicle body 1. The sealing cover 3 protects the gears 12 in the track 2 to reduce the influence of the external environment on the meshing point between the gears 12 and the track 2 when the gears 12 drive the track 2 to run. The motor inside the motor room 5 drives the gears 12 to rotate, thereby driving the track 2 to make the movable vehicle body 1 move along the foundation pit. When it moves to the designated location, the motor inside the motor room 5 stops running, and the detection component 8 detects the depth and angles on both sides of the bottom of the foundation pit through the second observation port 14 and the first observation port 13.

[0024] like Figure 3 , 4As shown, the detection component 8 includes a component box, a servo motor 21 is installed on the lower inner wall of the component box, the output end of the servo motor 21 is connected to a rack 22, and fixed brackets 23 are installed on both sides of the rack 22. The output end of the servo motor 21 contacts the rack 22, so that the servo motor 21 drives the detection component 8 to move on the slide rail 7. A mounting bracket 24 is provided on the upper inner wall of one side of the component box, and a laser detector 25 is installed above the inner wall of the mounting bracket 24. The laser detector 25 model is: Leica-DISTO-D510, which has high-precision measurement capabilities and IP65-level waterproof and dustproof performance. The upper inner wall and the corresponding lower inner wall of the component box away from the mounting bracket 24 are both installed with a connecting bracket 16. A guide rail 17 is installed between the two sets of connecting brackets 16 by bolts. The outer surface of the guide rail 17 is connected to a docking bracket 18 with a motor installed inside. A total station 20 is installed on the side of the docking bracket 18 away from the guide rail 17. The motor inside the docking bracket 18 drives the docking bracket 18 to move up and down on the guide rail 17, thereby driving the total station 20 to move. The model of the total station 20 is: Leica-MS60, which has a high-speed laser scanning function and excellent angle measurement and distance measurement accuracy, and can quickly obtain a large amount of point cloud data. A shock-absorbing shell 19 is installed on the outside of the total station 20, and a rubber strip is pasted inside the shock-absorbing shell 19 to reduce the vibration effect on the total station 20. A controller 26 is installed on the top of the component box, and the controller 26 is electrically connected to the servo motor 21, the laser detector 25, the motor inside the docking bracket 18, and the total station 20. A top cover 9 is installed above the controller 26 . The top cover 9 includes two sets of side panels 901 and a top panel 902 . The top cover 9 provides dustproof protection for the controller 26 .

[0025] During detection, the output end of the servo motor 21 contacts the rack 22, so that the servo motor 21 drives the detection component 8 to move on the slide rail 7. During the movement, the laser detector 25 will emit a laser through the second observation port 14 into the bottom of the foundation pit. When the laser is reflected by the reflector plate placed at the bottom of the foundation pit, the distance between the target point and the instrument is measured. At the same time, the motor inside the docking bracket 18 drives the docking bracket 18 to move on the guide rail 17, thereby driving the total station 20 installed inside the shock-absorbing shell 19 to move, so that the total station 20 detects the angles on both sides of the foundation pit through the first observation port 13.

[0026] Working principle: When using a positioning and installation detection device for power system infrastructure construction, the motor inside the motor room 5 drives the gear 12 to rotate, thereby driving the crawler 2 to make the movable vehicle body 1 move along the foundation pit. When moving to the designated location, the motor inside the motor room 5 stops running. At this time, the output end of the servo motor 21 contacts the rack 22, so that the servo motor 21 drives the detection component 8 to move on the slide rail 7. After moving, the laser detector 25 in the detection component 8 will emit a laser, and the laser passes through the second observation port 14 into the bottom of the foundation pit. When the laser is reflected by the reflector placed at the bottom of the foundation pit, the depth of the foundation pit is obtained. At the same time, the motor inside the docking bracket 18 drives the docking bracket 18 to move on the guide rail 17, thereby driving the total station 20 installed inside the shock-absorbing shell 19 to move, so that the total station 20 detects the angles on both sides of the foundation pit through the first observation port 13. After completing the first detection, the position of the mobile detection component 8 on the slide rail 7 is detected multiple times, and the average value is obtained as the detection record to complete high-precision information acquisition. At the same time, the detection component 8 moves on the slide rail 7 to avoid changes in the detection at the node caused by the movement of the movable body 1.
