Description

Technical Field

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

[0002] Currently, the identification of underwater defects and related information processing still primarily rely on sonar scanning imaging technology, with lasers and sonar being the main technologies for defect identification. While lasers are relatively mature on land, existing terrestrial laser equipment is clearly unsuitable for the complex and high-pressure underwater environment. Furthermore, due to the significant differences between underwater and terrestrial environments, different wavelengths of laser light are often required for different underwater conditions, necessitating a 3D laser scanner specifically designed for underwater operations.

[0003] However, existing 3D laser scanners have the following drawbacks:

[0004] (1) Existing 3D laser scanners have weak waterproofing capabilities. In order to facilitate underwater operations, the device itself needs to be waterproofed. Otherwise, water may enter the device and cause damage.

[0005] (2) Existing 3D laser scanners have weak fixed functions. When using them, the line device needs to be used with a special underwater robot as a carrier for underwater operations. However, each time the two are installed, tedious work is required, which may increase the workload of the staff. Utility Model Content

[0006] The purpose of this invention is to provide a three-dimensional laser scanner to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional laser scanner, comprising a scanner body, a fixing frame snapped onto the top and bottom of the scanner body, a waterproof shell fixedly connected to the bottom of the fixing frame, a rectangular groove formed on the top of the waterproof shell, a sealing cover snapped onto the top of the inner sidewall of the rectangular groove, a sealing gasket fixedly connected to the bottom edge of the sealing cover, a fixing bolt threadedly connected to the top edge of the sealing cover, a connecting rod fixedly connected to the bottom of the waterproof shell, a clamping plate fixedly connected to the outer surface of the connecting rod, a fixing seat snapped onto the outer surface of the clamping plate, and a positioning bolt threadedly connected to the side of the fixing seat.

[0008] Preferably, the front of the waterproof housing has a rectangular groove, and a transparent window is fixedly connected to the inner wall of the rectangular groove. The transparent window allows the device to emit the light that needs to be scanned. The scanner body model can be: Insight Pro.

[0009] Preferably, the fixed base has threaded grooves at both ends, and the inner wall of the threaded groove is threaded with mounting bolts. The operator needs to install the fixed base on the underwater body in advance using the mounting bolts. The underwater robot model that can be used is Remus-6000.

[0010] Preferably, the bottom of the sealing gasket is provided with a baffle, the outer surface of which is fixedly connected to the bottom of the inner wall of the rectangular groove at the top of the waterproof housing. The sealing cap covers the inner wall of the waterproof housing and is blocked by the baffle, making the components of the waterproof device fit together more closely.

[0011] Preferably, the top of the fixing base is provided with a docking groove, and the inner wall of the docking groove is engaged with the center of the outer surface of the connecting rod, so that the connecting rod will dock with the docking groove provided on the fixing base.

[0012] Preferably, the bottom side of the connecting rod is provided with a threaded groove, and the inner wall of the threaded groove is threaded to one end of the positioning bolt, and one end of the positioning bolt is screwed into the inner wall of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This 3D laser scanner, through the setup of the scanner body, fixed frame, waterproof shell, sealing cover, sealing gasket, and fixing bolts, allows the operator to place the scanner body into the fixed frame inside the waterproof shell during use, allowing the fixed frame to hold the scanner body in place. The sealing cover is then placed over the rectangular groove on the top of the waterproof shell, and the sealing gasket strengthens the seal between the sealing cover and the waterproof shell. The fixing bolts are then screwed into the threaded grooves where the sealing cover and the waterproof shell meet. This setup waterproofs the scanner body, reducing damage to the device during underwater operations.

[0015] 2. This 3D laser scanner, with its waterproof shell, connecting rods, clamping plate, fixing base, and positioning bolts, allows the operator to easily install the waterproof shell by inserting the connecting rods at both ends of the bottom of the waterproof shell into the fixing base, following the alignment of the clamping plate with the grooves on the fixing base. The connecting rods are then inserted into the inner wall of the bottom of the fixing base. The positioning bolts are then screwed into the threaded grooves on the fixing base and the connecting rods, and the waterproof shell is installed on the carrier. This design facilitates the installation operation for the operator. Attached Figure Description
