While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0039] How can we more stably ensure the buoyancy performance of nodes without affecting node coupling, thereby improving the reliability of underwater node recovery?

[0040] To address the aforementioned problems, this utility model provides a deep-sea node buoy, referring to... Figure 1 As shown, the deep-sea node buoy includes:

[0041] Marine exploration node 10, buoyancy control circuit, buoyancy device body, at least one node counterweight 3, electromagnetic coil 6 and pin 5;

[0042] The aforementioned marine exploration node 10 is snapped onto the lower end of the buoy body; at least one node counterweight 3 is disposed on the buoy body, each counterweight having a locking ring 7 at one end and being fixed by a pin 5 via the locking ring 7, while the other end is limited; an electromagnetic coil 6 and a buoyancy control circuit are disposed in the buoy body, and the electromagnetic coil 6 and the buoyancy control circuit are electrically connected; the pin 5 is movably disposed within the electromagnetic coil 6; the buoyancy control circuit is used to control the electromagnetic coil 6 to be energized according to a preset buoyancy signal, so as to push the pin 5 to pull out all the ring holes, disengage the node counterweight 3, and allow the buoy to float upward.

[0043] Reference Figure 2The enlarged view of the deep-sea node buoy shown indicates that one end of the aforementioned pin 5 can be pulled through the ring hole of the locking ring 7 to fix the locking ring 7. For example, in a specific implementation, two node counterweights 3 are provided on the main body of the buoy, and the corresponding two ring holes overlap. The pin 5 fixes the two counterweights by passing through the hole formed by the overlap of the two ring holes. When the buoyancy control circuit controls the electromagnetic coil 6 to be energized according to the preset buoyancy signal, the pin 5 is pushed out of all the ring holes, and the node counterweights 3 are separated from the main body of the buoy.

[0044] The deep-sea node buoy provided by this utility model adopts a structure of overlapping pull rings to lock the node counterweight 3 to the main body of the buoy. When the buoyancy control circuit receives the preset buoyancy signal, it controls the electromagnetic coil 6 to be energized, the pin 5 to be pulled out of all the pull ring holes, the node counterweight 3 to be disengaged from the node buoy, and the node buoy can float stably under the action of buoyancy. Moreover, this structure is simple and easy to implement, and can effectively improve the reliability of node recovery in the deep sea.

[0045] In one embodiment, the above-mentioned buoy body includes: an upper floating plate 2, a lower floating plate 9, and a vertical beam 8 connecting the upper floating plate 2 and the lower floating plate 9;

[0046] The aforementioned vertical beam 8 is connected to the upper floating plate 2 and the lower floating plate 9 respectively; the electromagnetic coil 6 is disposed on the upper floating plate 2; and the lower end of at least one counterweight is limited by the lower floating plate 9.

[0047] In one embodiment, when there are multiple node counterweights 3, the multiple counterweights are evenly distributed around the periphery of the main vertical beam 8 of the buoy, so that the deep-sea node buoy is subjected to balanced forces.

[0048] In one embodiment, the lower end of the aforementioned lower floating plate 9 is provided with a slot; the marine exploration node 10 is disposed within the slot.

[0049] In one embodiment, the upper end of the lower floating plate 9 is also provided with an anti-slip block 4; the lower end of at least one node counterweight 3 is located inside the anti-slip block 4 and is limited by the anti-slip block 4 to prevent the lower end of the node counterweight 3 from sliding out.

[0050] In one embodiment, the lower end of at least one node counterweight 3 is in contact with the anti-slip block 4 in the buoy body in a pointed shape. This shape of the lower end of the node counterweight 3 is beneficial for the node counterweight 3 to detach from the buoy body under gravity when the pin 5 is pulled out of the pull ring hole.

[0051] In one embodiment, the anti-slip block 4 has an inclined surface, and the lower end of the at least one node counterweight 3 is adapted to the inclined surface. In a specific implementation, the anti-slip block 4 may, for example, be trapezoidal, with one end of the trapezoidal angle located inside the lower float 9.

[0052] In one embodiment, when there are multiple node counterweights 3, each node counterweight 3 has the same weight, so that when multiple counterweights are evenly distributed around the outer perimeter of the main body vertical beam 8 of the buoy, the force exerted by the multiple counterweights on the entire deep-sea node buoy is balanced.

[0053] In one embodiment, the at least one node counterweight 3 is made of cement. Cement is a pollution-free material, which is more conducive to protecting the marine ecological environment.

[0054] In one embodiment, the aforementioned deep-sea node buoy further includes a buoy handle 1; the buoy handle 1 is located on the top of the buoy body, and the handle facilitates the lifting of the deep-sea node buoy from the water surface during node retrieval.

[0055] In one embodiment, the aforementioned deep-sea exploration node is also equipped with a positioning device and a strobe light.

[0056] The following is a specific example illustrating the working process of the deep-sea node buoy of this invention:

[0057] Reference Figure 1 As shown, the main body of the deep-sea node buoy in this example is equipped with two node counterweights 3, which are symmetrically distributed at both ends of the vertical beam 8. The deep-sea node buoy in this example is then deployed to the designated location.

[0058] In this example, the buoyancy control circuit is used to control the preset buoyancy signal for energizing the electromagnetic coil 6. This signal is the buoyancy command signal or low voltage protection signal received by the deep-sea node buoy after the set data acquisition time has elapsed, or when the power of the deep-sea node buoy is lower than the set value.

[0059] When the marine exploration node 10 has completed the set number of data collection days, or when the power of the deep-sea node's buoyancy chamber falls below a set value, the buoyancy control circuit, based on the aforementioned buoyancy signal, controls the electromagnetic coil 6 to energize, pushing the pins 5 to disengage from all the pull ring holes. At this time, all node counterweights 3 lose the locking of the pins 5 and, under the influence of gravity, tilt from both sides of the deep-sea node's buoyancy chamber. (Refer to...) Figure 3 The diagram shows the operational state of the deep-sea node buoyancy device after the node counterweight detaches from the counterweight 3. The deep-sea node buoyancy device, detached from the counterweight 3, rises under buoyancy; its rising state is shown in the diagram. Figure 4 As shown.

[0060] The surfaced deep-sea node buoy can be recovered according to the positioning of the marine exploration node 10 and the strobe light indication. After recovery, a new node counterweight 3 can be set on the main body of the buoy. The pin 5 can be manually pulled and re-inserted into the pull ring hole of the node counterweight 3 to fix the new node counterweight 3.

[0061] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
