Description

Technical Field

[0001] The present invention relates to a sliding guide rail type high-speed camera precise attitude determination and positioning device, and specifically relates to a sliding guide rail type high-speed camera precise attitude determination and positioning device, which is mainly suitable for measuring motion parameters such as the spatial three-dimensional position and attitude of a high-speed moving target in a closed water target channel, and belongs to the technical field of underwater high-speed moving target testing. Background Art

[0002] Generally speaking, the application of underwater high-speed cameras to measure the three-dimensional position and attitude of underwater high-speed moving targets is becoming more and more widespread. In the application of underwater target position and attitude measurement, the high-speed camera needs to be deployed underwater. After deployment, the position and attitude of the underwater high-speed camera must be stable and can be accurately measured.

[0003] Currently, underwater high-speed cameras are generally deployed underwater using multi-section connecting rods. This deployment method has the following shortcomings:

[0004] 1. The camera is placed underwater via a connecting rod. Affected by water fluctuations, the underwater camera will inevitably shake to a certain extent. This makes it impossible to ensure the stability of the underwater camera's position and posture, and cannot meet the requirements of high-precision posture measurement of underwater targets.

[0005] 2. To ensure reliable connection, the connecting rods are usually heavy. The connecting rods need to be lifted by electric hoists and require the cooperation of multiple people. The placement process is complicated, difficult and time-consuming.

[0006] 3. Since the camera is deployed at different depths underwater by splicing multiple connecting rods, and the length of the connecting rods is fixed, the deployment depth can only be the length of several connecting rods, and the camera deployment depth cannot be arbitrarily adjusted according to the target depth.

[0007] Therefore, the key to solving the above technical problems is to develop a sliding guide rail type high-speed camera precise attitude positioning device with strong practicality and high working reliability. Summary of the Invention

[0020] As a further preferred technical solution of the present invention, the mounting member (234) is symmetrically arranged on both sides of the telescopic power cylinder (231); the stop block (233) is composed of two pieces, and the two stop blocks (233) are symmetrically mounted on the two mounting members (234).

[0021] As a further preferred technical solution of the present invention, an anti-rust layer, a waterproof layer and a warning layer are sprayed on the outer surfaces of the sliding guide rail (1) and the high-speed camera precise attitude positioning device (2) in sequence from the inside to the outside, and the warning layer is coated with fluorescent powder.

[0022] The working principle is: before using the sliding guide rail type high-speed camera precise attitude determination and positioning device of the above-mentioned design structure, it is necessary to install the already manufactured sliding guide rail type high-speed camera precise attitude determination and positioning device of the above-mentioned design structure as a spare.

[0023] Before installation, the operator only needs to install the present invention in the underwater high-speed moving target test target track, and use it for underwater high-speed camera attitude positioning measurement in the water target track high-speed moving target measurement.

[0024] The water target channel (3) is a closed water pool with a length of 150m, a width of 6m and a depth of 6m. To ensure the safety of underwater high-speed moving target testing, a pair of grooves (31) are set at a certain distance on both sides of the water target channel (3), and underwater high-speed cameras (4) and other measuring equipment are installed in the grooves (31).

[0025] During installation, the sliding guide rail (1) is installed on the bottom plate of the groove (31) by bolts. During installation, the two sliding guide rails (1) are parallel and perpendicular to the horizontal plane by adjusting the mounting bolts. The underwater high-speed camera (4) is composed of a high-speed camera, a watertight shell, a high-precision tilt sensor, a watertight cable assembly, etc. The underwater high-speed camera (4) and the tilt sensor are installed in the watertight shell. The watertight shell is installed on a camera mounting support (212) with holes of the high-speed camera precise attitude positioning device (2). The pitch angle of the underwater high-speed camera (4) is adjusted and fixed by the camera mounting support (212) with holes. After the underwater high-speed camera (4) is installed, it is used.

[0026] During use, an operator installs the high-speed camera precise attitude positioning device (2) on two sliding guide rails (1) with the assistance of a hoisting device (5), and the sliding wheel (222) and the auxiliary sliding wheel (225) of the high-speed camera precise attitude positioning device (2) are clamped on both sides of the sliding guide rails (1), so that the high-speed camera precise attitude positioning device (2) slides closely against the sliding guide rails (1), and the device deployment depth is observed by the hoisting cable (51). When the device reaches the deployment depth, it stops sliding, and the telescopic power cylinder (231) is screwed in to tighten the wedge block (232), so that the stop block (233) presses against the two sides of the sliding guide rails (1), so that the underwater high-speed camera (4) is fixed at the deployment depth, thereby achieving position positioning. The direction of the connecting line of the two sliding guide rails (1) is measured by the theodolite, and the horizontal attitude information of the high-precision tilt sensor is obtained, so as to achieve the precise attitude of the underwater high-speed camera.

[0027] During the entire implementation process described above, the sliding wheel (222) and the auxiliary sliding wheel (225) cooperate with each other. When the device is installed on the sliding guide rail (1), the sliding wheel (222) and the auxiliary sliding wheel (225) are located on both sides of the sliding guide rail (1). The sliding guide rail (1) squeezes the meshed sliding wheel (222) and the auxiliary sliding wheel (225) apart, and the auxiliary sliding wheel (225) is tightened by the elastic member (226), so that the sliding wheel (222) and the auxiliary sliding wheel (225) slide closely on the sliding guide rail (1) to prevent the sliding wheel (222) from derailing or the high-speed camera precise attitude positioning device (2) from tipping over.

[0028] When the high-speed camera precise attitude positioning device (2) needs to be locked, the telescopic power cylinder (231) is driven to rotate the tightening wedge block (232) to squeeze the stop blocks (233) on both sides, so that the stop blocks (233) are pressed against the two sliding guide rails (1), thereby fixing the high-speed camera precise attitude positioning device (2) on the sliding guide rails (1). When the high-speed camera precise attitude positioning device (2) needs to slide and rise on the sliding guide rails (1), the telescopic power cylinder (231) is used to rotate the tightening wedge block (232), the two stop blocks (233) are retracted, and the high-speed camera precise attitude positioning device (2) can slide freely.

[0029] The beneficial effects of the present invention compared with the prior art are:

[0030] 1. The present invention can be used for underwater camera positioning in closed water target channel high-speed moving target testing. The device has a simple structure and is easy to deploy. It can effectively solve the problems of complex deployment operation of underwater high-speed cameras and difficulty in ensuring the accuracy of camera deployment posture.

[0031] 2. The present invention observes the deployment depth of the device by hanging a cable. When the device reaches the deployment depth, it stops sliding down. The motor rotates the tightening wedge block, causing the stop block to press against the sliding guide rails on both sides, so that the underwater high-speed camera is fixed at the deployment depth, achieving position positioning and realizing that the camera deployment depth can be arbitrarily adjusted according to the target depth;

[0032] 3. The present invention uses a theodolite to measure the direction of the line connecting the two sliding guide rails and obtain the horizontal posture information of the high-precision tilt sensor, thereby achieving accurate positioning of the underwater high-speed camera. This solves the problems of complex deployment and recovery of underwater cameras and unstable positioning of underwater cameras.

[0033] 4. The present invention is deployed underwater using a hoisting cable and mounted on two sliding rails with the aid of a hoisting device. The device's sliding wheels and auxiliary sliding wheels snap into place on both sides of the sliding rails, allowing the device to slide closely against the rails. This prevents the underwater camera from shaking to a certain extent due to water fluctuations, ensuring a stable position and attitude of the underwater camera, and meeting the requirements for high-precision posture measurement of underwater targets to the greatest extent possible.

[0034] 5. The present invention is easy to install and operate, does not require the cooperation of multiple people, has a simple deployment procedure, is easy to operate, saves time and effort, and can greatly reduce the labor intensity of the staff while also improving work efficiency and ensuring work safety;

[0035] 6. The exterior of the present invention is coated with an anti-rust layer and a waterproof layer, thereby preventing rust and extending the service life of the entire positioning device, achieving environmental protection while saving resources. At the same time, the exterior of the positioning device is coated with a self-luminous fluorescent material, which can clearly mark the position of the positioning device at night or in a dark room and underground construction environment, effectively serving as a safety reminder, improving visibility, making it easy for people to identify, and increasing safety in construction and life.

[0068] Before using the sliding guide rail type high-speed camera precise attitude determination and positioning device of the above-mentioned design structure, the already manufactured sliding guide rail type high-speed camera precise attitude determination and positioning device of the above-mentioned design structure needs to be installed as a spare.

[0069] Before installation, the operator only needs to install the present invention in the underwater high-speed moving target test target track, and use it for underwater high-speed camera attitude positioning measurement in the water target track high-speed moving target measurement.

[0070] The water target channel 3 is a closed pool with a length of 150m, a width of 6m and a depth of 6m. To ensure the safety of underwater high-speed moving target testing, a pair of grooves 31 are set at a certain distance on both sides of the water target channel 3. Underwater high-speed cameras 4 and other measuring equipment are installed in the grooves 31.

[0071] During installation, the sliding guide rail 1 is installed on the bottom plate of the groove 31 by bolts. During installation, the two sliding guide rails 1 are parallel and perpendicular to the horizontal plane by adjusting the mounting bolts. The underwater high-speed camera 4 is composed of a high-speed camera, a watertight shell, a high-precision inclination sensor, a watertight cable assembly, etc. The underwater high-speed camera 4 and the inclination sensor are installed in the watertight shell, and the watertight shell is installed on the camera mounting bracket 212 with holes of the high-speed camera precise attitude positioning device 2. The pitch angle of the underwater high-speed camera 4 is adjusted and fixed by the camera mounting bracket 212 with holes. The underwater high-speed camera 4 is used after installation.

[0072] During use, the operator installs the high-speed camera precise positioning device 2 on two sliding rails 1 with the assistance of the hoisting device 5. The sliding wheels 222 and auxiliary sliding wheels 225 of the high-speed camera precise positioning device 2 snap into place on both sides of the sliding rails 1, allowing the device 2 to slide closely against the sliding rails 1. The device's deployment depth is observed using the hoisting cable 51. When the device reaches the deployment depth, it stops sliding. The telescopic power cylinder 231 is screwed in to tighten the wedge block 232, causing the stop block 233 to press against the two sliding rails 1, securing the underwater high-speed camera 4 at the deployment depth and achieving positioning.
