Description

Technical Field

[0001] This utility model relates to the field of laser scanner technology, specifically a portable underwater 3D laser scanner. Background Technology

[0002] With the continuous expansion of underwater operation scenarios, from underwater structure detection in shallow sea areas to biological habitat mapping in deep sea areas, portable underwater 3D laser scanners have become an indispensable core equipment in fields such as underwater exploration, cultural relics archaeology, and engineering inspection due to their advantage of being able to quickly acquire 3D information of underwater target objects.

[0003] Currently, when using portable underwater 3D laser scanners to scan underwater scenes, the scanners are mostly equipped with fixed counterweights, which makes it impossible to adjust them flexibly according to the actual water flow. This can easily cause the scanner to deviate from its target position (such as tilting or swaying), resulting in the laser scanning path deviating from the target and reducing the scanner's scanning accuracy. Therefore, a portable underwater 3D laser scanner is needed. Utility Model Content

[0004] The purpose of this invention is to provide a portable underwater 3D laser scanner to solve the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution: This utility model is a portable underwater 3D laser scanner, comprising: The laser scanner body has a connecting seat at its bottom end, and fixing plates are fixed on both sides of the top end of the connecting seat. The counterweight component includes a fixed cylinder, one end of which is provided with a connecting rod. A first elastic block is fixedly provided at the top of the outer wall of the connecting rod. A limiting block is fixedly provided at one end of the connecting rod. A spring is fixedly provided on one side of the limiting block. A baffle is rotatably provided at the other end of the connecting rod. A support rod is provided through the bottom end of one side of the baffle. A counterweight block is slidably provided on the outer wall of the support rod. One end of the support rod is fixedly connected to one side of the connecting seat.

[0005] Furthermore, the counterweight components are provided in four sets, and are symmetrically arranged on opposite sides of the two fixed plates.

[0006] Furthermore, the counterweight component also includes a slide bar, one side of which is fixedly mounted on the outer wall of the connecting rod, and the outer wall of the slide bar penetrates one end of the fixed cylinder.

[0007] Furthermore, one end of the spring is fixedly connected to one end inside the fixed cylinder.

[0008] Furthermore, a positioning post is fixedly provided at the center of the top of the connector, and the top of the positioning post is engaged with the bottom of the laser scanner body.

[0009] Furthermore, it also includes a fixing component, which includes four vertical rods. The bottom ends of the four vertical rods are symmetrically arranged at the top ends of the two fixing plates. Each of the four vertical rods has a rotating plate rotatably mounted at its top end. Each of the four rotating plates has a second elastic block engaged at its top end, and the bottom end of the second elastic block is fixedly connected to the top end of the laser scanner body.

[0010] Furthermore, the opposite sides of the two fixing plates respectively contact the two sides of the laser scanner body.

[0011] This utility model has the following beneficial effects: This invention utilizes a baffle and a counterweight. Pulling the baffle outward stretches the spring until the first elastic block moves outside the fixed cylinder. Then, the baffle is rotated upward to a vertical position, and the counterweight is added or removed from the support rod. The baffle is then rotated in the opposite direction to a vertical position, and the first elastic block is pressed inward. Under the elastic action of the spring, the baffle moves inward until it is tightly fitted with the outermost counterweight of the support rod. This method allows for flexible adjustment of the laser scanner's counterweight according to the actual water flow, preventing scanner posture deviations (such as tilting or wobbling), ensuring the laser scanning path follows the target, and thus improving the scanner's scanning accuracy.

[0015] 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.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a portable underwater 3D laser scanner, comprising: The laser scanner body 11 has a connecting seat 12 attached to its bottom end, and fixing plates 13 are fixed on both sides of the top end of the connecting seat 12. The laser scanner body 11 adopts the ULS-500 PRO model. Its principle is to accurately calculate the three-dimensional coordinates of the object surface by emitting a laser beam and receiving the reflected signal, thereby constructing a high-precision three-dimensional model.

[0018] The counterweight component includes a fixed cylinder 21, a connecting rod 22 passing through one end of the fixed cylinder 21, a first elastic block 23 fixedly provided at the top of the outer wall of the connecting rod 22, a limiting block 24 fixedly provided at one end of the connecting rod 22, a spring 25 fixedly provided on one side of the limiting block 24, a baffle 26 rotatably provided at the other end of the connecting rod 22, a support rod 27 passing through the bottom end of one side of the baffle 26, a counterweight block 28 slidably provided on the outer wall of the support rod 27, and one end of the support rod 27 fixedly connected to one side of the connecting seat 12. The connecting rod 22 is slidably engaged with the fixed cylinder 21. One end of the fixed cylinder 21 is fixedly mounted on one side of the fixed plate 13. The outer wall of the limiting block 24 is in contact with the inner wall of the fixed cylinder 21. When the first elastic block 23 moves to the outside of the fixed cylinder 21, one side of the baffle 26 does not contact the outer wall of the support rod 27. When the baffle 26 rotates upward to the vertical position, the bottom end of the baffle 26 is higher than the top end of the counterweight 28. This makes it convenient to add or remove the counterweight 28 on the support rod 27 and avoid motion interference. The support rod 27 and the baffle 26 are slidably engaged.

[0019] Four sets of counterweight components are provided, and they are symmetrically arranged on opposite sides of the two fixed plates 13. Symmetrically arranged counterweights can improve the overall balance of the laser scanner.

[0020] The counterweight component also includes a slide bar 29, one side of which is fixedly mounted on the outer wall of the connecting rod 22, and the outer wall of the slide bar 29 penetrates one end of the fixed cylinder 21; The slide bar 29 is used to guide the movement of the connecting rod 22, and the outer wall of the slide bar 29 slides in conjunction with the fixed cylinder 21.

[0021] One end of the spring 25 is fixedly connected to one end inside the fixed cylinder 21.

[0022] A positioning post 14 is fixedly provided at the center of the top of the connector 12, and the top of the positioning post 14 is engaged with the bottom of the laser scanner body 11. The positioning post 14 is used for connection and positioning between the connecting seat 12 and the laser scanner body 11. The bottom end of the laser scanner body 11 is provided with a positioning hole that matches the positioning post 14.

[0023] Working principle: Before scanning the water body, the laser scanner body 11 is placed in the water. According to the actual flow rate of the water, the baffle 26 is pulled outward. The outward movement of the baffle 26 drives the limiting block 24 to move outward through the connecting rod 22. The outward movement of the limiting block 24 stretches the spring 25 until the first elastic block 23 moves outside the fixed cylinder 21. Then, the baffle 26 is rotated upward to a vertical position. Then, counterweights 28 are added or removed from the support rod 27. Then, the baffle 26 is rotated in the opposite direction to a vertical position and the first elastic block 23 is pressed inward. Under the elastic action of the spring 25, the baffle 26 moves inward until the baffle 26 is tightly fitted with the outermost counterweight 28 of the support rod 27. Similarly, the same number of counterweights 28 are added or removed from the other support rods 27. In this way, the counterweight of the laser scanner can be flexibly adjusted according to the actual water flow, avoiding the scanner's posture deviation (such as tilting or shaking), and ensuring that the laser scanning path follows the target, thereby improving the scanning accuracy of the scanner.

[0024] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The fixing component includes four vertical rods 31. The bottom ends of the four vertical rods 31 are symmetrically arranged at the top ends of two fixing plates 13. The top ends of the four vertical rods 31 are rotatably provided with rotating plates 32. The top ends of the four rotating plates 32 are engaged with second elastic blocks 33, and the bottom ends of the second elastic blocks 33 are fixedly connected to the top end of the laser scanner body 11. The top of the rotating plate 32 has a locking hole that matches the second elastic block 33.

[0025] The opposite sides of the two fixing plates 13 are in contact with the two sides of the laser scanner body 11, respectively.

[0026] Working principle: After the laser scanner body 11 is used, press down on the second elastic block 33 and rotate the rotating plate 32 outward until the rotating plate 32 rotates outward to the horizontal position. Then move the laser scanner body 11 upward to separate it from the connecting seat 12. This modular connection method makes it easy to disassemble and assemble the laser scanner body 11 and the connecting seat 12, thereby improving the convenience of overall transportation.
