The fixed block 100 is used for connection with a marine scope and the base 301 is used for connection with a counterweight. When the counterweight descends to strike the sea floor, the fixed block 100 continues to move downward under the action of inertia, and at this time, the fixed block 100 and the mount 300 compress the elastic member 900, and the hanging ring 200 is separated from the clamping groove 500. Under the action of the resilience force of the elastic member 900 and the buoyancy of the marine observation instrument, the marine observation instrument drives the fixed block 100 and the hanging ring 200 to ascend, and the hanging ring 200 is separated from the clamping groove 500, so that the marine observation instrument is separated from the counterweight, and the counterweight is released. By the structure, the counterweight can be automatically released when the counterweight contacts the seabed.
Specifically, the fixing block 100 is disposed above the base 301, the fixing block 100 is rectangular, and a through hole is formed in the fixing block 100. The hanging ring 200 is waist-round, one end of the hanging ring 200 is arranged in the through hole in a penetrating way, and the hanging ring 200 can rotate in the through hole.

When the counterweight descends to strike the sea floor, the base 301 and the fixed block 100 are ensured to be close to each other under the guide of the sleeve 800, so that the compression and rebound of the compression spring are realized, the hanging ring 200 is separated from the releasing action of the clamping groove 500, and the success rate of releasing is improved.
Further, the inner cross-sectional shape of the sleeve 800 is the same as the cross-sectional shape of the base 301. And the cross-section of the base 301 has at least one straight edge. Specifically, the base 301 is a rectangular block, the sleeve 800 is a rectangular tube, and the base 301 slides in the sleeve 800. By this arrangement, the base 301 is prevented from rotating inside the sleeve 800, resulting in the hanging ring 200 being separated from the catching groove 500, improving the stability of the structure.
Further, the inner side and the outer side of the sleeve 800 are rounded, and the corresponding side of the base 301 is rounded.
