Description

Technical Field

[0001] This invention relates to the field of power transmission and transformation engineering construction and acceptance technology, and more specifically, to an acceptance device based on multi-sensor fusion technology. Background Technology

[0002] Currently, power transmission and transformation construction workers face numerous practical problems such as high turnover, severe aging, low education levels, and insufficient skills training. They cannot adequately meet the State Grid's requirements that "technicians must understand calculations, safety officers must be able to conduct acceptance inspections, and responsible persons must be able to prohibit violations." The current actual operations are not scientific or intelligent enough, and generally rely on physical observation, measurement with the help of ordinary instruments, and manual calculations. In particular, in accurately obtaining information about guy wires, ground anchors, and nearby live conductors, scientific tools are not used, and work is carried out based on experience, resulting in low work efficiency and even widespread unknowing violations. Therefore, it is necessary to empower key personnel in work teams by developing a safety enforcement measure acceptance device based on multi-sensor fusion technology to reduce on-site safety risks.

[0003] In addition, during actual measurement and acceptance, construction personnel need to carry multiple measurement and acceptance instruments, which is cumbersome. Furthermore, since the measurement locations are mostly in the field, the uneven ground makes it difficult to carry out the measurement and acceptance work effectively. After setting up the scaffolding, the staff need to adjust the angle and orientation multiple times to find the measurement baseline, which consumes a lot of time and reduces the efficiency of the measurement and acceptance work.

The first form is the conventional ground form, which is set up by the cooperation of two corresponding support members hinged to the bottom of the slider and the support member hinged to the bottom of the connecting ring, so as to meet the use on uneven ground and facilitate folding and carrying. The second form slides the two corresponding support members hinged to the bottom of the slider along the arc-shaped slide groove and rotates to the other end, so that the two corresponding support members hinged to the bottom of the slider are parallel. Then, the mounting holes on the arc-shaped clip are fixed by bolts and nuts, which can fix the entire device to such as tree trunks, utility poles, etc., and can be used on the slope in the field where no flat ground can be found, thus expanding the applicability of the device.

[0027] Example 1

[0028] Please see Figure 1-5 The acceptance device based on multi-sensor fusion technology includes a mounting plate 100. The mounting plate 100 is provided with a cross groove 310 for the equipment cavity 510 to swing. Two arc grooves 311 are provided on the outside of the cross groove 310 for the quick adjustment mechanism 110 to rotate. The mounting plate 100 and the connecting ring 140 are fixedly connected by multiple connecting blocks 150. The mounting plate 100 is provided with a quick adjustment mechanism 110 for adjusting the observation angle.

[0029] The rapid commissioning mechanism 110 has a testing device 120 at its top for measurement and acceptance. A camera is mounted above the testing device 120 for capturing image information. The rapid commissioning mechanism 110 includes an equipment box 410, which contains an equipment cavity 510 for installing testing and transmission equipment, and a gas detection cavity 520. A gas detector is installed in the gas detection cavity 520. A battery is installed inside the equipment box 410. The multi-sensor fusion technology integrates laser ranging, tilt angle, acceleration, and CCD sensors to achieve... Optical ranging, tilt angle, acceleration, wind speed, gas detection, CCD and other sensor technologies are used for on-site measurement of angle, depth, distance, wind speed, toxic gas, etc. The transmission equipment is RS232 serial port data transmission or Bluetooth, etc., to transmit the measurement data to mobile devices such as PPC, data logger, GPS receiver, etc., to easily realize real-time wireless data transmission. Using RS232 serial port data transmission or Bluetooth, it can realize near, far, multi-target continuous measurement mode. The bottom of the gas detection chamber 520 is equipped with an adjustment component 130 for the angle of the limit quick adjustment mechanism 110.

[0030] The quick-adjustment mechanism 110 also includes a rotating ring 413. The bottom of the rotating ring 413 is provided with an annular groove. Multiple ball heads 415 are slidably installed inside the annular groove. The number of ball heads 415 is at least 4. If there are 4 ball heads 415, they are arranged in a cross shape. If there are more than 4 ball heads 415, they are arranged equidistantly in a circle. Multiple ball heads 415 are fixedly connected to the top of the mounting plate 100 and are located between the cross groove 310 and the arc groove 311. The equipment box 410 is rotatably installed between the inner walls of the rotating ring 413 via the connecting rod 414. The outer wall of the rotating ring 413 is provided with two extension blocks 416 that slide along the two arc grooves 311. The bottom of each extension block 416 is fixedly connected with a semicircular plate 320. The semicircular plate 320 is provided with a semicircular groove 321. The center of the semicircular groove 321 is consistent with the center of the connecting rod 414. The outer wall of the semicircular plate 320 is provided with a toothed section. The top of the extension block 416 is threaded with a fastening bolt for limiting position.

[0031] A bracket 411 is fixedly connected to the top of the equipment box 410, and a turntable 412 is fixedly connected to the top of the bracket 411. An anemometer 430 for detecting wind speed is installed between the turntable 412 and the equipment box 410. The bracket 411 is hollowed out on all four sides to allow natural wind to pass through and detect wind speed. A rotating seat 210 is fixedly connected to the top of the turntable 412. The outer wall of the rotating seat 210 is provided with anti-slip teeth to facilitate rotation. A detection device 120 is installed on the top of the rotating seat 210. The rotating seat 210 can rotate the detection device 120 to a position such that... Figure 7 In this state, the rotating seat 210 can also be a gimbal. Fixed rods 417 are fixedly installed on the bottom of both sides of the outer wall of the equipment box 410. The fixed rods 417 are slidably installed inside the adjacent semicircular grooves 321. The end of the fixed rods 417 away from the equipment box 410 is fixedly connected to a limit block 418. When the equipment box 410 rotates along the connecting rod 414, the fixed rods 417 slide along the semicircular grooves 321.

[0032] The adjustment assembly 130 includes a tensioning member 330, which includes a first fixed cylinder 530 fixedly connected inside the gas detection chamber 520. A sliding column 531 is slidably installed inside the first fixed cylinder 530. A first spring 532 is fixedly connected between the sliding column 531 and the inner wall of the first fixed cylinder 530. A pressing rod 340 is fixedly connected to the bottom of the sliding column 531. Both ends of the pressing rod 340 are fixedly connected to arc-shaped racks 341. The arc-shaped racks 341 mesh with the toothed segments on the semi-circular plate 320. A handle 342 is fixedly connected to the bottom of the pressing rod 340. The outer wall of the gas detection chamber 520 is provided with air inlets 540. By setting the tensioning member 330, the arc-shaped racks 341 on the pressing rod 340 can always be engaged with the toothed segments on the outer wall of the circular plate 320 to limit and fix the angle of the quick adjustment mechanism 110.

[0033] In use, the user expands the support mechanism 160 to secure the quick-adjustment mechanism 110 stably. Once the quick-adjustment mechanism 110 is stable, the user pulls the handle 342 to pull the arc-shaped rack 341 on the clamping rod 340 away from the toothed segment on the semicircular plate 320 it meshes with. Since the equipment box 410 contains testing equipment and a battery, it rotates along the connecting rod 414. Due to gravity, the equipment box 410 remains vertical, and the top plane of the turntable 412 is parallel to the horizontal line. Then, the user releases the handle 342, causing the arc-shaped rack 341 on the clamping rod 340 to disengage from the semicircular plate 320. The gear segments on 0 re-engage, completing the fixation of the equipment box 410 after angle adjustment. Then, the rotating seat 210 and the detection device 120 are installed on the turntable 412, reducing the time for subsequent fine-tuning of the detection device 120. It does not shake during use, and can be quickly fixed in different ground conditions, avoiding the need for staff to adjust the angle and orientation multiple times to find the measurement baseline after supporting the tripod. It also reduces the time spent adjusting the support tripod and lowers the overall difficulty of operating the instrument. Furthermore, it is more flexible to use on rugged roads or dirt roads, and can quickly locate the target point, improving the efficiency of measurement and acceptance work.
