[0005] However, in the above technical solution, the counterweight cone cannot be firmly clamped on the seabed, and cannot automatically adjust the height with the wave, and when there is a wind wave, the buoyancy tank will move the counterweight cone, resulting in failure to recover smoothly.

The tow rope supports the first counterweight, limiting the float's movement range and preventing it from drifting away with the waves, thus facilitating subsequent recovery.

[0022] Example 1, as Figures 1-3 As shown, the present invention proposes a marine hydrological observation device, which includes a float 1, a balance bar 2, a first counterweight 3, a traction rope 4, a positioning block 7, and a hydrological observation device body 14.

[0023] The main body 14 of the hydrological observation device is set at the upper end of the float 1, which has a semi-elliptical structure; the balance bar 2 is set at the lower end of the float 1; the first counterweight 3 is set at the lower end of the balance bar 2; one end of the traction rope 4 is set on the positioning block 7; the other end of the traction rope 4 is equipped with a winding mechanism; the traction rope 4 is slidably set at the lower end of the first counterweight 3; and a locking rod 8 is rotatably set on the positioning block 7.

[0024] Multiple sets of locking rods 8 are provided; a torsion spring 802 for rotating the locking rods 8 is provided on the positioning block 7; a locking component 801 is provided on the locking rods 8; a locking mechanism 9 is provided on the positioning block 7; the locking mechanism 9 engages with the locking component 801.

[0025] The clamping mechanism 9 comprises a clamping block 901, a sliding rod 902 and an elastic member 903; the sliding rod 902 is arranged on the clamping block 901; the sliding rod 902 is slidingly arranged on the positioning block 7; the elastic member 903 is arranged on the outer circumferential side of the sliding rod 902; the two ends of the elastic member 903 are respectively connected with the clamping block 901 and the positioning block 7; the lower end of the clamping block 901 is provided with a clamping groove 904; the clamping piece 801 is in a horizontal L-shaped structure; one end of the clamping piece 801 is embeddedly arranged in the clamping groove 904; and the clamping piece 801 is clamped with the clamping block 901.

[0026] The lower end of the sliding rod 902 is provided with a push plate 10; the push plate 10 protrudes from the lower end of the positioning block 7. The outer circumferential side of the sliding rod 902 is provided with a protection buckle 11; the protection buckle 11 is in a U-shaped structure; the protection buckle 11 is detachably connected with the sliding rod 902; and the two ends of the protection buckle 11 are respectively abutted with the push plate 10 and the positioning block 7.

[0027] The upper end of the clamping rod 8 is provided with a plug 12; a plurality of plugs 12 are arranged; the plugs 12 can be inserted into the seabed, so as to increase the fixing effect.

[0028] The upper end of the floating block 1 is provided with a solar panel 13; the solar panel 13 is electrically connected with a hydrological observation device body 14; power can be generated through the solar panel 13, so as to supply power to the hydrological observation device body 14; a storage battery is arranged in the floating block 1; the power generated by the solar panel 13 is stored in the storage battery, and then provided to the hydrological observation device body 14.

[0029] In this embodiment, during transportation, the elastic element 903 pushes the locking block 901 to lock onto the locking member 801, causing the locking rod 8 to be housed within the positioning block 7. The protective buckle 11 is engaged between the push plate 10 and the positioning block 7, supporting the push plate 10 and preventing it from pushing the slide rod 902 to move, thus causing the locking block 901 to separate from the locking member 801. After moving to the designated observation position, the protective buckle 11 is removed, and the positioning block 7 is thrown into the sea. The traction rope 4 is connected to the upper end of the positioning block 7 to guide it, allowing the push plate 10 to contact the seabed first. After the push plate 10 contacts the seabed, it pushes the slide rod 902 to move upward, which in turn pushes the locking block 901 upward, causing the locking block 901 to separate from the locking member 801. The torsion spring 802 drives the locking rod 8 to flip, which in turn causes the pin 12 to flip, allowing the pin 12 to be inserted. Upon reaching the seabed, the positioning block 7 is supported, and the locking rod 8, once deployed, increases the probability of securing the device to seabed corals or other materials, thus supporting the tow rope 4. The float 1 and the reel-in float 6 are then thrown into the sea. The first counterweight 3 moves the balance bar 2 downwards, the tow rope 4 supports the first counterweight 3, and the balance bar 2 supports the float 1, causing the upper end of the float 1 to float above the sea surface. This allows the hydrological observation device body 14 to be positioned above the sea surface, enabling marine hydrological observation. The balance bar 2 and the first counterweight 3 keep the float 1 vertical on the sea surface. The second counterweight 5 supports the tow rope 4, and the reel-in float 6 collects any excess tow rope 4. The tow rope 4 supports the first counterweight 3, limiting the range of movement of the float 1 and ensuring it does not drift away with the waves, facilitating subsequent recovery.

[0030] Example 2, as Figures 1-3 As shown, the marine hydrological observation device proposed in this invention, compared with Embodiment 1, has a line-retrieving mechanism that includes a second counterweight 5 and a line-retrieving float 6; the other end of the traction rope 4 is disposed on the line-retrieving float 6; the second counterweight 5 is slidably disposed on the traction rope 4 and is located between the first counterweight 3 and the line-retrieving float 6.

[0031] In the embodiment, the float 1 provides buoyancy to support the balance bar 2, the balance bar 2 supports the first counterweight 3, the first counterweight 3 supports the traction rope 4, the second counterweight 5 is pressed on the traction rope 4, so that the traction rope 4 is in a U-shaped structure at the lower end of the first counterweight 3, and the take-up float 6 stores the plurality of traction ropes 4, and the take-up float 6 floats on the sea surface to support the second counterweight 5 and the traction rope 4; so as to ensure the moving range of the float 1, and when there is a large wind wave, the float 1 and the take-up float 6 move with the wave, drive the traction rope 4 to move, the second counterweight 5 is pressed on the traction rope 4, and the take-up float 6 automatically stores or releases part of the cable according to the actual use, so that the float 1 has a moving space and can better resist the wind wave.

[0032] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited thereto, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
