[0023] As shown in the figure, a portable coral reef survey instrument includes: an underwater structure 1, and a display component 2 connected to the underwater structure 1 through a cable 13.

[0024] It should be noted that this survey instrument includes two parts, namely a display component 2 and an underwater structure 1. The underwater structure 1 and the display mechanism are connected through a cable 13. The underwater structure 1 has been waterproofed or is a waterproof device, so as to prevent water from entering the device during the process of the underwater structure 1 entering the water and causing damage to the device. The underwater structure 1 is used to detect and investigate the distribution of underwater coral reefs, the underwater topography and landforms, and the placement and distribution of artificial fish reefs.

[0025] The underwater structure 1 includes: a frame, and a tail fin plate 10 provided on one side of the frame; an underwater camera is also provided on the frame, and an underwater LED lamp (12) is provided on one side of the underwater camera.

[0029] In a preferred embodiment of the present utility model, the connecting frame 15 includes two connecting plates, two semi-circles are symmetrically arranged in the middle of the connecting plates, and one of the two connecting plates is fixedly connected to the connecting shaft.

[0030] It should be noted that the support frame 14 is vertically arranged as a whole. The support frame 14 includes two circular ring shafts and a plurality of support shafts. The circular ring shafts are arranged in a circular ring shape, and the circles of the two circular ring shafts are located on the same axis. The support shafts are fixedly connected to the outer circumference of the two circular ring shafts; there are two connecting shafts, and the two connecting shafts are symmetrically arranged. The connecting shafts are fixedly connected to the circular ring shafts. The cross-section of the two connecting shafts connected to the upper circular ring shaft is an isosceles triangle. The connection point between the two connecting shafts is the apex angle of the isosceles triangle, and the connection point between the two connecting shafts and the circle of the circular ring shaft are located on the same axis. A small circular ring is also fixedly connected to the top between the two connecting shafts. The small circular ring is used to fix the cable 13. Through the fixation between the cable 13 and the small circular ring, the operation of putting the underwater structure 1 into the water for monitoring and observing the coral reef and pulling it out of the water is realized; there are two connecting plates, namely the main connecting plate and the auxiliary connecting plate. The two ends of the main connecting plate are respectively fixedly connected to the two connecting shafts. Threaded holes are provided on both the main connecting plate and the auxiliary connecting plate. The main connecting plate and the auxiliary connecting plate are connected by bolts through the threaded holes. Two semi-circular arcs are arranged in the middle position of the main connecting plate and the auxiliary connecting plate. After the main connecting plate and the auxiliary connecting plate are fixed, the semi-circular arcs on each of them form two circular holes. The two circular holes are used to fix the underwater camera and the underwater LED lamp (12) respectively. The auxiliary connecting plate is arranged inside the support frame 14 to protect the underwater camera and the underwater LED lamp (12).

[0031] The display component 2 includes: a deck unit 20; an LCD liquid crystal screen is arranged on the deck unit 20, and the LCD liquid crystal screen is used for real-time display of the underwater coral reef investigation picture. The deck unit 20 is connected to the underwater camera and the underwater LED lamp (12) through the cable 13 respectively.

[0032] In a preferred embodiment of the present utility model, a storage hard disk and a communication module are arranged in the deck unit 20, and the storage hard disk is used for storing pictures and video recording files.

[0033] In a preferred embodiment of the present utility model, a positioning module and a processing module are further arranged in the deck unit 20; the processing module adopts ffmpeg technology to decode and process the original video stream.

[0034] In a preferred embodiment of the present utility model, the cable 13 adopts an 8-core Kevlar connection cable.

[0035] It should be noted that an LCD liquid crystal screen is arranged on the deck unit 20, and a control module, a storage hard disk, a communication module, a positioning module and a processing module are further arranged in the deck unit 20.

[0036] The tail fin plate (10) is vertically arranged in a plate-like structure, and the tail fin plate (10) is fixedly connected to the frame.

[0037] It should be noted that the tail fin plate is vertically arranged as a whole and is fixedly connected to the frame. In this way, during the sinking process of the device, the tail fin plate increases the contact area between the whole device and the water flow, and thus makes the water flow generate greater resistance when flowing through the tail fin plate. This resistance is a stable force for the whole device and helps to resist the water flow impacts from different directions. Similarly, in a complex water flow environment, the device will be affected by water flows from different directions and intensities, resulting in attitude deviation. Similarly, the tail fin plate corrects and maintains the vertical attitude of the underwater unit through the resistance generated by the water flow in other directions. This automatic correction mechanism ensures that the survey instrument can maintain a stable attitude during long-term underwater operations, thereby improving the accuracy and reliability of the data.

[0038] When the present utility model is in use, the connection deck unit 20 controls a high-definition camera and an LED lamp through the control module, and provides a power supply and a data transmission channel through the cable 13, so as to investigate and monitor the distribution status of underwater coral reefs, the submarine topography and landforms, and the placement and distribution status of artificial fish reefs. Through the ffmpeg technology, the original video stream is decoded, and is transmitted to the LCD liquid crystal screen in real time and stored in the storage hard disk. Moreover, the longitude and latitude coordinate data of the current coral reef survey site are obtained in real time through the positioning unit, and the current coral reef survey picture and video files are generated through the processing module, and the coral reef record index information is generated.

[0039] Based on the inspiration of the ideal embodiments of the present utility model, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
