In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a large number of other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0028] Embodiment 1, as shown in the present application, the buoy intelligent ventilation device comprises a shaft 2; Figures 1-2

[0029] The top of the shaft 2 is closed with a hatch cover 3 isolated from the outside world; the shaft 2 is fixed on the shaft shell 18; the shaft shell 18 is fixedly connected with the instrument cabin 1;

[0030] The inner upper part of the shaft 2 is provided with a ventilation component for circulating and discharging the humid air in the instrument cabin 1, which is powered by the wave energy to force the air in the instrument cabin 1 to complete one inhalation and exhalation ventilation work with the wave energy at each wave peak and wave valley.

[0031] The ventilation component air pipe 15 is communicated with the instrument cabin 1; the air outlet of the air pipe 15 is located at the instrument cabin left side top opening 19 of the instrument cabin 1;

[0032] The instrument cabin 1 is communicated with the mast 4 located at the upper part of the instrument cabin 1; the rainproof outlet structure 16 is installed on the upper part of the mast 4; the air outlet 20 of the rainproof outlet structure 16 is communicated with the external air.

[0033] Exemplarily, the ventilation component comprises a derrick 8 fixedly installed on the side wall of the shaft 2;

[0034] The upper part of the derrick 8 is hingedly connected with a hinge 9; the hinge 9 is fixedly connected with a swing frame 6;

[0035] The upper part of the derrick 8 is also hingedly connected with the upper branch 701 of a branch-shaped connecting rod 7;

[0036] The lower left branch 702 of the branch-shaped connecting rod 7 is hingedly connected with the lower part of the swing frame 6 through a bearing 12;

[0037] The lower right branch 703 of the branch-shaped connecting rod 7 is hingedly connected with a piston 10;

[0038] The piston 10 is installed on a connecting pipe 13; the connecting pipe 13 is fixed on the derrick 8; the connecting pipe 13 is connected with the air pipe 15;

[0039] A sealing gasket 11 is arranged on the piston 10. ​

[0040] The connecting pipe 13 is provided with a sliding groove 17, and the piston 10 moves linearly along the sliding groove 17.

[0041] A float 5 is mounted on the lower part of the swing frame 6 via a float mounting plate 14.

[0042] The float 5 is located at the set water level line 21;

[0043] For example, the lower left branch 702 of the support-shaped connecting rod 7 is hinged to the lower part of the swing frame 6 via a bearing 12. Under the action of gravity of the float 5, the support-shaped connecting rod 7 can be driven to naturally return to its initial state (e.g., Figure 2 );

[0044] Working principle:

[0045] Utilizing the principle of wave energy, when the seawater in wellbore 2 is below the set water level, the float 5 remains stationary under the influence of gravity. Figure 2 As shown, the shaft 2 and the instrument compartment 1 are kept open through the vent pipe 15. The air in the closed shaft 2 is powered by the wave energy and forms an air passage from the top opening 19 on the left side of the instrument compartment to the air outlet 20 of the rainproof outlet structure 16. This forces the air in the instrument compartment 1 to follow the wave energy to complete one intake and exhaust operation at each wave peak and trough. The formed air passage circulates and exhausts the relatively humid air in the instrument compartment 1.

[0046] Utilizing the principle of buoyancy, once the seawater in the wellbore exceeds the set water level in adverse sea conditions, the float 5 will rise, driving the piston 10, which is hinged to the lower right branch 703 of the drive rod 7, to close the vent pipe 15. The air in the instrument compartment 1 will be sealed off, and no air intake or exhaust will be performed to prevent seawater from flowing back in.

[0047] For example, such as Figure 3 A top view showing multiple intelligent buoy ventilation devices arranged around the instrument compartment 1; in order to more effectively circulate and exhaust the relatively humid air inside the instrument compartment 1, multiple intelligent buoy ventilation devices can be arranged around the instrument compartment 1; where A, B, and C represent intelligent buoy ventilation devices arranged around different parts of the instrument compartment 1.

[0048] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the scope of the technology disclosed in the present utility model, within the spirit and principles of the present utility model, should be included within the protection scope of the present utility model.
