Description

Technical Field

[0001] The present invention relates to the technical field of marine scientific exploration equipment, in particular to a deployment platform for seabed equidistant observation. Background Art

[0002] In marine scientific research, observation equipment often needs to be placed underwater via hanging cables to observe the seabed. However, due to the unevenness of the seabed and the swells during seabed observations, the seabed observation platform connected to the research vessel via a 10,000-meter optical cable will rise and fall. This causes the distance between the camera and the seabed to fluctuate during observations, and the captured images are affected by distance and lighting, resulting in a decrease in quality. At the same time, seabed sediments and rocks reflect light differently, so if the light intensity remains constant during observation, the observation effect will be affected. To solve this problem, it is necessary to automatically adjust the light intensity according to image quality feedback during observation. Summary of the Invention

[0003] The present invention is aimed at equipment that needs to be placed underwater to observe the seabed. It provides a deployment platform for seabed equidistant observation that is easy to retract and deploy, can solve the problem of the distance between the camera and the seabed fluctuating, and can adjust the camera lighting intensity.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A deployment platform for equidistant observation of the seabed, comprising an equipment frame, a hanging device, a 10,000-meter cable connector, and a control cabin. The hanging device and the cable connector are arranged at the top of the equipment frame, the hanging device is hingedly fixed to the equipment frame, the cable connector is fixedly connected to the hanging device, the control cabin is arranged in the equipment frame, the equipment frame is provided with a lighting lamp, a camera, an altimeter, a hydraulic station, a hydraulic cylinder, and a battery box, the end of the hydraulic cylinder telescopic rod is arranged below the equipment frame, the lighting lamp and the camera are arranged at the end of the hydraulic cylinder telescopic rod, the telescopic rod of the hydraulic cylinder is extended to half of its extendable distance in the initial state, the cable connector, lighting lamp, camera, altimeter, hydraulic station, and battery box are electrically connected to the control cabin respectively, and the hydraulic cylinder is connected to the hydraulic station. In this solution, an altimeter is installed at the bottom of the equipment frame, which can collect the distance between the device and the sea level in real time. Therefore, when the distance between the seabed and the sea level is known, the distance between the device and the seabed can be directly obtained. After the distance signal is fed back to the control cabin, the control cabin sends a signal to the hydraulic station according to the distance between the device and the seabed, and drives the hydraulic cylinder to extend (when the distance is far) or retract (when the distance is close), thereby keeping the distance between the camera and the seabed constant; if the change distance of the altimeter is greater than the extension and retraction distance of the hydraulic cylinder, the people on the ship can control the hanging device and lengthen the cable so that the device can be closer or farther away from the bottom; in addition, the camera transmits the picture to the control cabin, and the control cabin verifies the image quality through the program, so as to independently judge whether the light intensity should be increased or decreased. The lighting on the device (such as LED lights) will respond accordingly and adjust to the appropriate light intensity to cooperate with the camera to take pictures.

[0006] Preferably, the equipment rack is equipped with a deployment device, and the bottom of the equipment rack is provided with equipment to be deployed, which is connected to the deployment device. In this solution, it can also be used as a submarine equipment deployment platform, where the equipment rack carries the equipment to be deployed to the seabed, and after the camera finds the optimal deployment position, the equipment to be deployed can be lowered.

[0007] Preferably, the equipment frame includes an upper fixing frame and a lower fixing frame, and the upper fixing frame and the lower fixing frame respectively include an annular ring beam, and the annular ring beam is provided with a longitudinal beam and a transverse beam. The upper fixing frame and the lower fixing frame are connected by a column, and a hanging plate is provided in the middle of the upper fixing frame to connect with the hanging device.

[0008] Preferably, the deployment device comprises a connecting rope and two sets of deployers, each of which is equipped with a release device. The ends of the connecting rope are connected to the release devices of the two deployers, respectively, and the connecting rope passes through the equipment to be deployed. This solution employs two sets of deployers, which can serve as a backup. That is, if one set of deployers fails, as long as one is operational, one end of the connecting rope can be released, and the equipment to be deployed can still slide off the connecting rope to complete the deployment operation.

[0009] Preferably, the deployment device is an acoustic releaser, a hydraulic releaser, or an electronically controlled releaser. The deployment device of this solution has a release hook at the bottom. Upon receiving a signal, the release hook automatically opens, allowing the connecting rope (e.g., with loops at both ends through which the release hook passes) to be detached.

[0010] Preferably, the hydraulic cylinders are provided in two groups, one on each side of the equipment rack. Each side of the equipment rack is provided with an outwardly extending mounting rod, which is secured to the bottom of the hydraulic cylinders. In this embodiment, the two hydraulic cylinders can each carry a set of lights and cameras, thereby expanding the seabed observation range. Alternatively, one set of lights and cameras can be used in conjunction with the other set as a backup.

[0011] Compared with the prior art, the present invention has the following advantages: it is easy to retract and extend, can solve the problem of the varying distances between the camera and the seabed, can adjust the intensity of camera illumination, and can accurately place the equipment to be deployed.

The end of the telescopic rod of the hydraulic cylinder 9 is located below the equipment frame 1. The lighting lamp 5 and the camera 6 are located at the end of the telescopic rod of the hydraulic cylinder 9. In the initial state of the hydraulic cylinder 9, the telescopic rod extends half of its extendable distance. The cable connector 3, the lighting lamp 5, the camera 6, the altimeter 7, the hydraulic station 8, and the battery box 10 are electrically connected to the control compartment 4 respectively. The hydraulic cylinder 9 is connected to the hydraulic station 8.

[0024] There are two groups of hydraulic cylinders 9 , which are respectively arranged on both sides of the equipment frame 1 . Both sides of the equipment frame 1 are respectively provided with outwardly extending mounting rods 15 , which are fixed to the bottom of the hydraulic cylinders 9 .

[0025] The specific usage process is as follows: In this solution, an altimeter 7 is installed at the bottom of the equipment frame to collect the distance between the device and the sea level in real time. After the distance signal is fed back to the control cabin 4, the control cabin 4 sends a signal to the hydraulic station 8 according to the distance between the device and the seabed, and drives the hydraulic cylinder 9 to extend or retract, thereby maintaining the distance between the camera 6 and the seabed constant; if the change in distance is greater than the extension and retraction distance of the hydraulic cylinder 9, the crew on the ship can control the hanging device 2 to lengthen or shorten the cable, so that the device can be closer to or farther away from the bottom.
