Description

Technical Field

[0001] The invention relates to a submerged buoy device, in particular to an elastically suspended bottom-sitting submerged buoy device. Background Art

[0002] Most of the submerged buoy equipment currently used on the seabed is deployed in an anchored manner. The so-called anchored structure is generally composed of a submerged buoy, a releaser, and a weight. The three are connected by ropes or steel wires, and the submerged buoy is suspended on the seabed. The anchored structure connection form is simple and reliable, so it is widely used. However, because it is a flexible connection and the equipment is suspended in the sea, the equipment is affected by the ocean current and shakes greatly, affecting the performance of the equipment. In addition, when deployed in an anchored manner, the equipment is often far above the seabed and is easily caught by fishing or passing leisure boats, and the safety and concealment are poor.

[0003] The present invention is an elastically suspended bottom-seated submerged buoy device. The buoy body and the jettisoning frame are connected in an elastically suspended manner. The submerged buoy is entirely located on the seabed. This connection method greatly reduces the connection size of the submerged buoy, and greatly improves the seabed concealment and anti-salvage performance. In addition, the connection stiffness of the elastically suspended bottom-seated submerged buoy is also significantly improved. The submerged buoy will not sway significantly with the ocean current during service, and the stability of the equipment performance is more reliable. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will provide embodiments of the present invention in conjunction with the accompanying drawings, and further illustrate the structure and working principle of the present invention through the embodiments.

[0023] It should be noted that the terms and words used below are not limited to the literal meanings, but are used by the inventor to enable a clear and consistent understanding of the present invention. Therefore, it is obvious to those skilled in the art that the following description of various embodiments of the present invention is provided only for illustrative purposes and not for the purpose of limiting the present invention as defined by the attached claims and their equivalents.

[0024] like Figure 1-3 , which is a schematic diagram of the device of the present invention. The elastic suspension type bottom-seating submersible buoy device designed by the present invention comprises a buoy body 100 and a throwing frame 200:

[0025] The target body 100 includes a float 110, a releaser 120 and a target body bottom plate 130;

[0026] The jettisoning frame 200 includes a suspension device 210 and an elastic support device 220;

[0027] The float 110 is fixedly connected to the base plate 130 of the target body; the releaser 120 is placed inside the float 110 and fixedly connected to the base plate 130 of the target body; the suspension device 210 is connected to the releaser 120 , and the elastic support device 220 is connected to the suspension device 210 .

[0028] In the marker body: the float 110 provides the buoyancy required for the submerged buoy to float up, the marker body bottom plate 130 is a load-bearing plate, and the releaser 120 is an acoustic device.

[0029] The releaser 120 is a three-part releaser, including a releaser battery compartment 121, a releaser electronic compartment 122, a hydroacoustic transponder 123 and a release ring 124; the releaser battery compartment 121, the releaser electronic compartment 122 and the hydroacoustic transponder 123 are electrically connected, the releaser battery compartment 121 and the releaser electronic compartment 122 are fixed on the base plate 130 inside the float 110, the hydroacoustic transponder 123 is fixed above the float 110, and the release ring 124 is connected to the releaser electronic compartment 121.

[0030] When the three-part releaser is working, the releaser battery compartment 121 serves as the power source of the releaser 120, and supplies power to the releaser electronic compartment 122 and the hydroacoustic transponder 123. The hydroacoustic transponder 123 receives hydroacoustic signals through the high-frequency transmitting transducer 143 and the low-frequency transmitting transducer 144 in the functional device. When it is necessary to release the buoy, the buoy is placed in the sea to a certain depth, and the release instruction code is input through the human-computer interaction interface. The electrical signal of the release instruction is converted into a hydroacoustic signal by the high-frequency transmitting transducer 143 or the low-frequency transmitting transducer 144 and sent out. When the hydroacoustic transponder 123 receives the sent hydroacoustic release signal, it converts the hydroacoustic signal into an electrical signal and transmits it to the releaser electronic compartment 122. After receiving the instruction, the releaser electronic compartment 122 drives the releaser 120 to move, opens the release hook on the releaser electronic compartment 121, and completes the release instruction. Then, the electrical signal of the release completion is converted into an acoustic signal by the acoustic transponder 123 and sent out. After receiving the acoustic signal, the high-frequency transmitting transducer 143 or the low-frequency transmitting transducer 144 converts it into an electrical signal and transmits it to the human-computer interaction interface, indicating that the release is successful.

[0031] In the jettison rack:

[0032] The suspension device 210 includes a coupling frame 211, a threaded hook 212, a butterfly nut 213, a bracket 214 and a dumping base plate 215; the threaded hook 212 is a connecting component, the butterfly nut 213 is a fastener, the coupling frame 211 is a supporting base frame, the coupling frame 211 is welded to 8 brackets 214, the dumping base plate 215 is welded to the lower inner side of each bracket 214, and the threaded hook 212 is threadedly connected to the butterfly nut 213.

[0033] The elastic support device 220 includes a compression spring 221, a compression spring guide column 212 and a cotter pin 223; the cotter pin 223 is a fastener, the compression spring guide column 212 is a guide component, the compression spring 221 is an elastic component between the standard body 100 and the ejection rack 200, the compression spring 221 is mounted on the outer periphery of the compression spring guide column 212, and the cotter pin 223 is inserted into the compression spring guide column 212 to lock the compression spring 221.

[0034] The above-mentioned suspension device and elastic support device act together on the bottom-seated submerged buoy, so that the body 100 is in a suspended support state, which can play a certain degree of buffering role on the body 100 when the submerged buoy is dropped and sinks to the seabed, preventing the body 100 from being damaged by a large impact. In addition, when the submerged buoy is dumping, the elastic potential energy of the compression spring 221 can be converted into kinetic energy for the body 100 to float up, accelerating the floating of the body 100; and, the elastic suspension type bottom-seated submerged buoy device of the present invention has a more reliable structure, a smaller size, and a stronger anti-salvage performance.

[0035] In addition, the target body 100 also includes functional equipment, which includes a depth sensor 141, a Beidou positioning device 142, a high-frequency transmitting transducer 143, a low-frequency transmitting transducer 144, a hydrophone 145, an amplifier cabin 146, an electronic cabin 147 and a battery cabin 148; the depth sensor 141, the power amplifier cabin 146, the electronic cabin 147 and the battery cabin 148 are fixed on the target body bottom plate 130, the Beidou positioning device 142, the high-frequency transmitting transducer 143, the low-frequency transmitting transducer 144 and the hydrophone 145 are fixed above the floating body 110, and the depth sensor 141, the Beidou positioning device 142, the high-frequency transmitting transducer 143, the low-frequency transmitting transducer 144 and the hydrophone 145 are electrically connected to the power amplifier cabin 146, the electronic cabin 147 and the battery cabin 148 respectively.

[0036] The depth sensor 141 can be used to read the sinking depth and sinking speed of the buoy in the sea, and data protection can be set through software. In the event of abnormal surfacing or abnormal operation, the depth sensor will trigger a self-destruction command to self-destruct the data; the Beidou positioning device 142 has its own strobe light, which can easily find the location of the marker 100; the high-frequency transmitting transducer 143 and the low-frequency transmitting transducer 144 are used to transmit signals; the hydrophone 145 is used to collect propagation signals in the water; the power amplifier cabin 146 plays the role of amplifying power, and is used to amplify signals and amplify sound; the electronic cabin 147 is used to store circuit boards that can execute algorithms and commands; the battery cabin 148 is used to power various functional devices.

[0037] like Figure 4 The figure shows a schematic diagram of the elastic suspension assembly of the jettisoning frame of the present invention. The compression spring 221, the compression spring guide column 222 and the cotter pin 223 together constitute the elastic support device 220 of the latent buoy. The compression spring 221 is sleeved on the compression spring guide column 222, one end of which passes through the mounting hole of the coupling frame 211 and is assembled with the coupling frame 211 through the cotter pin 223. The buoy body 100 is press-fitted on the jettisoning frame 200 through the above-mentioned elastic support device, and the compression spring 221 is compressed to a certain state under the gravity of the buoy body 100.

[0038] The compression and locking process of the elastic support device is as follows: rotate the butterfly nut 213 to further compress the compression spring 221 to a specified state (the interval between the buoy body and the bearing surface of the coupling frame 240 is 8mm-12mm), then lock the butterfly nut 213 to keep the compression spring 221 in the compressed state. This locking distance determines the elastic potential energy of the compression spring 221, which can improve the structural stability of the buoy and ensure the connection stiffness. If the interval is too small, the buffering capacity of the compression spring 221 will be weakened when the buoy is located on the seabed; if the interval is too large, the locking force between the buoy body 100 and the jettisoning frame 200 is insufficient, and the buoy body 100 is prone to shaking.

[0039] The coupling frame 211 is a circular support frame, and the dumping base plate 215 is two circular flat plates placed up and down with the center of the circle as the axis and hollowed out in the middle, and the area of ​​the upper circular flat plate is smaller than that of the lower circular flat plate. This dumping base plate 215 can increase the contact pressure with the seabed when the buoy is thrown into the seabed, and prevent the coupling frame 211 from sinking into the seabed mud. The compression spring 221, the threaded hook 212 and the release ring 124 are all on the dumping base plate 215, which can well prevent the compression spring 221 and the release ring 124 from being covered by mud. If the compression spring 221 is covered by mud for a certain period of time, its elastic potential energy will be weakened, and in severe cases, the compression spring 221 may not be able to recover and the elasticity may fail. If the release ring 124 is in the mud, it will directly cause the release ring 124 to fail to fall off smoothly, the release fails, and the equipment cannot be recovered normally. Therefore, the dumping base plate 215 structure will greatly improve the reliability of the smooth recovery of the equipment.

[0040] like Figure 5 As shown, the threaded hook 212 passes through the center hole of the coupling frame 211, and the reverse side cooperates with the butterfly nut 213. The threaded hook 212 is hooked on the release ring 124 to assemble into a suspension device 210, which serves as a sinking bottom component of the bottom-seated buoy. The butterfly nut 213 is rotated, and the rotational movement of the butterfly nut 213 is converted into a linear displacement of the threaded hook 212. Under the conduction of force, the distance between the buoy body 100 and the jettisoning frame 200 is further shortened, and the compression spring 221 is further compressed. When the distance between the buoy body bottom plate 130 and the coupling frame 211 is 8mm-12mm, the butterfly nut 213 is locked.

[0041] The specific operation process of the elastic suspension type bottom-sitting submersible buoy device of the present invention is as follows:

[0042] First, the target body 100 is directly placed on the ejection rack 200, and the target body bottom plate 130 is in direct contact with the compression spring guide column 222 of the ejection rack 200 to generate a force. The compression spring guide column 222 is displaced in its free direction by the force, and the force is transmitted to the compression spring 221 through the compression spring guide column 222, and the compression spring 221 is compressed by the gravity.

[0043] Secondly, pass the threaded hook 212 through the center hole of the coupling frame 211, connect the butterfly nut 213 to the lower part of the threaded hook 212, hook the upper part of the threaded hook 212 on the release ring 124, rotate the butterfly nut 213, and when the distance between the base plate 130 of the standard body and the coupling frame 211 is 8mm-12mm, tighten the butterfly nut 213 to ensure that the standard body 100 obtains sufficient buoyancy potential energy so that it can float quickly when the release ring 124 is discarded.

[0044] Finally, the buoy is dropped, and the release ring 124 is discarded by the releaser 120, and the body 100 floats to the water surface. The body 100 serves as the floating part of the buoy, and the throwing frame 200 serves as the sinking part of the buoy. When the body 100 is connected to the throwing frame 200, the sinking force of the throwing frame 200 in the water is greater than the buoyancy of the body 100, and the gravity of the buoy is greater than the buoyancy of the water. After the buoy is dropped, it will sink freely to the seabed. The release ring 124 can be discarded by controlling the hydroacoustic transponder 123 in the releaser 120 to achieve the separation of the body 100 and the throwing frame 200. After separation, the body 100 loses the constraint of the throwing frame 200, and the buoyancy of the water on the body 100 is greater than its own gravity. Under the buoyancy of the water, the body 100 floats to the water surface.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the invention patents and are not intended to limit them. Although the invention patents are described in detail with reference to the embodiments, those skilled in the art should understand that any modification or equivalent replacement of the technical solutions of the invention patents does not deviate from the spirit and relevant scope of the invention patents and should be covered within the scope of the claims of the invention patents.
