Problems solved by technology

Take the "Jiaolong" manned submersible as an example. This is a deep-sea manned submersible independently developed by my country. It can reach 7000m deep sea for exploration and testing. The "Jiaolong" is a platform for observation equipment and other operating tools. Only the sampling baskets located under the observation window at the front end are allowed, and there are strict restrictions on the weight, volume, mechanical and electrical interfaces, and operation methods of the equipped equipment.

Embodiment 1

[0030] Embodiment one: see Figure 1 to Figure 9 , the present invention is a three-dimensional camera fixing and adjusting device for in-situ observation of deep-sea organisms suitable for carrying operations on deep-sea manned submersibles. The fixed adjustment device on the submersible is characterized in that:

[0031]1) The three-dimensional camera for in-situ observation of deep-sea organisms is composed of camera cabin A, computer scanning unit cabin, and camera cabin B. It adopts the principle of laser high-speed line scanning binocular vision to monitor the individual morphological parameters of deep-sea reptiles or sessile organisms. In-situ measurement, according to the working principle, the 3D camera can only carry out normal shooting work within its designed working depth of field;

[0032] 2) The fixed adjustment device for mounting the 3D camera specially developed for in-situ observation of deep-sea organisms on the "Jiaolong" manned submersible is: fixedly i...

Embodiment 2

[0033] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0034] The base support mechanism is hinged by a channel steel lower base and a channel steel upper base through a channel steel connecting shaft and a channel steel base gasket, and is connected to the sampling basket by a square U-bolt and a square bolt connection plate Above; when it is necessary to fix the connection between the three cabin planes of the 3D camera and the sampling basket at different angles, it can be realized by adjusting the relative position of the channel steel upper base and the channel steel lower base through the channel steel connecting shaft, the channel steel lower base and the channel steel lower base The front end of the sampling basket is fixed by square U-bolts and square U-bolt connecting plates, and the channel steel base gasket is placed between the lower base of the channel steel and the front end of the sampling basket to...

Embodiment 3

[0041] Embodiment 3: The three-dimensional camera for in-situ observation of deep-sea organisms involved in this embodiment is as follows: Figure 5 As shown, in order to achieve the purpose of deep-sea hydrostatic high pressure resistance, each unit of the 3D camera adopts a separate package form, which is composed of camera cabin 1, calculation and scanning unit cabin 2 and camera cabin 3. The 3D camera adopts the principle of laser high-speed line scanning binocular vision to measure in situ individual morphological parameters and extract and reconstruct biological characteristic parameters of deep seabed reptiles or sessile organisms, and then completely construct a 3D point cloud image of the entire object surface. As an example, Figure 5 The total width of the 3D camera shown is 1200mm, the calculated scanning unit cabin 2 has a height of 592mm, an outer diameter of 154mm, an inner diameter of 130mm, a cabin wall thickness of 11mm, and the material is titanium alloy TC4; ...

Abstract

The invention relates to a fixing and adjusting device for a three-dimensional camera for in-situ observation of deep-sea organisms, which is suitable for the carrying operation of a deep-sea manned submersible. Its three-dimensional camera consists of two camera cabins and a computational scanning unit cabin. The fixed adjustment device includes two base support mechanisms, one clamp mechanism for the computing and scanning unit cabin, one oblique support mechanism, and one part of the connection mechanism between the sampling basket and the oblique support. Under the premise of the basket structure, the 3D camera is firmly fixed on the sampling basket, and it is convenient to adjust the angle of the 3D camera for in situ scanning and measurement of deep-sea organisms. The 3D camera comes close to the seabed with the submersible, adjusts the depth of the submersible, keeps the hovering and stable of the submersible, and starts the 3D camera to shoot; Depth, keep the submersible hovering and stabilizing, and start the 3D camera to shoot.

Description

technical field [0001] The invention relates to a deep-sea biological in-situ observation three-dimensional camera fixing and adjusting device suitable for deep-sea manned submersible carrying operations, which provides a fixed adjustment device for deep-sea three-dimensional cameras for deep-sea manned submersibles equipped with deep-sea three-dimensional cameras for biological in-situ observation s installation. Background technique [0002] There are a large number of rich biological resources in the deep sea to be further investigated, recognized, researched and developed by people. Traditional biological sampling systems based on mechanical grabbing, deep-sea dragging or pump filtration cannot maintain the in-situ environment in the deep sea, resulting in the collection of biological samples. Almost all of them died at the surface of the water, unable to meet the needs of scientists for understanding marine life. After the emergence of deep-sea submersibles, it is poss...
