Description

Technical Field

[0001] This invention relates to the field of naval technology, and in particular to an intelligent device for underwater detection of naval vessels. Background Technology

[0002] Submarine-based oceanographic surveying can detect the thermocline in the submarine's operating area, allowing the submarine to utilize the acoustic shadow created by the refraction of sound rays within the thermocline for concealment. The advent of submarine-deep thermometers has fundamentally changed the detection of seawater temperature and depth data. Reconnaissance is conducted using underwater acoustic and non-underwater acoustic detection equipment such as sonar and magnetodetectors. Real-time measurements of oceanographic elements in the submarine's operating area are performed using oceanographic observation equipment installed on the submarine. These measurements primarily include seawater temperature, salinity, density, pressure, sound velocity, and temperature-salinity-depth profiles. The data is processed, displayed, and stored in real time, providing marine hydrological environmental information for submarine navigation and concealment.

[0003] Our experimental team has long been reviewing and researching a large amount of relevant data on ship and underwater monitoring technologies. Simultaneously, relying on relevant resources and conducting numerous experiments, we discovered, through searches, that existing technology CN112684750B discloses an underwater intelligent monitoring device for sand dredgers, which relates to the field of underwater acoustic target monitoring technology. In this device, the acoustic sensor module collects signals that are converted into voltage signals by a transmitter. These voltage signals are then acquired by a data acquisition module. A digital signal processing module processes the signals acquired by the data acquisition module, and a feature extraction module extracts signal features. These features are then compared with data in a sample library module. A threshold is set for the sample library module, and the differences in features between the acquired signal and the signals in the sample library are compared. If the differences do not exceed the threshold, an alarm is returned to the early warning module; if the differences exceed the threshold, it indicates a significant difference between the signal data in the sample library module and the acquired signal features, and the system does not alarm. The data acquisition module and the signal processing module are connected via a communication module, and a power supply module provides power to the device.

[0004] This invention addresses the common problems in the field where, during underwater detection operations by ships, the monitoring devices are easily damaged by environmental influences, and ships cannot promptly retrieve them; the release and retrieval efficiency of the detection devices is also low. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings existing in the field by proposing an intelligent device for underwater detection of ships.

[0006] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

The system includes a telescopic drive motor for connecting and fixing the base plate to drive the fixed base plate to move up and down, a closed groove continuously provided along the side plate of the fixed base plate, an annular airbag continuously laid on the bottom wall of the closed groove, a ventilation pipe embedded inside the fixed base plate and with one end penetrating through the groove wall of the closed groove to airtightly communicate with the annular airbag, an inflation / deflation pump connected to the other end of the ventilation pipe for controlling the inflation and deflation of the airbag strip, and a cooperating door for controlling the communication between the communication channel and the outside of the ship.

[0010] Furthermore, the release module includes a transmission rod horizontally disposed on the bottom wall of the fixed base plate, a traction rope with one end fixed to the outer wall of the transmission rod and wound sequentially around the outer wall, a spiral groove continuously disposed on the outer wall of the transmission rod for orderly winding of the traction rope, a fixed shell for sleeved and fixed to the exterior of the underwater equipment, a locking member for fixedly connecting the release end of the traction rope to the fixed shell, at least two bearing seats for movably fixing the transmission rod to the fixed base plate, an external gear sleeved on the outer wall of the transmission rod, a retraction drive mechanism that meshes with the external gear and drives the transmission rod to rotate synchronously by driving the rotation of the external gear, a directional drive mechanism for clamping the fixed shell in the release chamber and further driving the fixed shell to move to the communication channel, and a drive mechanism for driving the fixed shell located in the communication channel out of the communication channel to the underwater area of ​​the ship, wherein the traction rope has a hollow structure inside, and the hollow structure inside the traction rope is the hollow cavity of the traction rope.

[0011] Furthermore, the retraction and extension drive mechanism includes an opening groove recessed from the bottom wall of the fixed base plate and extending upward therefrom; a drive chamber disposed inside the fixed base plate and isolated from the opening groove; a rotating rod rotatably mounted horizontally within the opening groove via a bearing mounting seat; transmission teeth sleeved on the outer wall of the rotating rod and meshing with the external gear; a communication port connecting the drive chamber and the opening groove; a drive motor installed inside the drive chamber and corresponding to a power output shaft passing through the communication port to be fixedly connected to one end of the rotating rod, thereby driving the rotating rod to rotate; and at least one airtight bearing component whose corresponding outer ring is sealed within the inner wall of the communication port and whose corresponding inner ring is airtightly sleeved within the outer shaft wall of the power output shaft.

[0012] Furthermore, the driving mechanism includes an inflatable airbag strip fitted onto the hollow cavity of the traction rope, an inflation port disposed on the airbag strip, an inflation tube at least partially embedded in the transmission rod and having one end sequentially passing through the transmission rod and the hollow cavity and further communicating with the inflation port, an inflation pump communicating with the other end of the inflation tube for inflating the airbag strip, an exhaust branch pipe located in the storage chamber and having one end communicating with the side wall of the inflation tube, an exhaust pump communicating with the exhaust branch pipe, a first electrically controlled valve controlling the communication between the inflation tube and the inflation pump, and a second electrically controlled valve controlling the communication between the exhaust branch pipe and the inflation tube.

[0013] The beneficial effects achieved by this invention are:

[0014] 1. The present invention uses the airbag strip to work in an airtight contact with the side wall of the storage chamber and / or release chamber to isolate the water ingress area in the release chamber from the storage chamber until the recovery module discharges the water in the release chamber, thereby ensuring the safety of underwater equipment and other electrical equipment placed in the storage chamber.

[0015] 2. The retraction and release drive mechanism of the present invention realizes the rotation drive operation of the transmission roller through the power output shaft that passes through the communication port, while the drive chamber and the opening groove are isolated from each other to prevent water entering the release chamber from entering the drive chamber through the opening groove, thereby improving the service life of the drive motor.

[0016] 3. This invention uses a transmission roller to release the traction rope and a drive mechanism to move the fixed shell, thereby driving the underwater equipment from the communication channel to the underwater surface of the ship. This allows the fixed shell and the underwater equipment it holds to be driven to a preset depth in the water area for underwater inspection operations. Based on the depth of the underwater equipment for inspection operations, the traction rope is used to pull the underwater equipment to the preset depth for inspection operations. Furthermore, the shearing device can be used to deploy the underwater equipment to deep water areas for long-term inspection operations. Based on the position information of the fixed shell, the fixed shell floating on the water surface can be directionally searched and retrieved, thus effectively improving the efficiency of underwater equipment deployment.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to its embodiments. It should be noted that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this invention. Other systems, methods, and / or features of this embodiment will become apparent to those skilled in the art after reviewing the following detailed description. Furthermore, the terminology used to describe positional relationships in the accompanying drawings is for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0026] Example 1: Combined with Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 This embodiment constructs an intelligent device for underwater detection of ships;

[0027] An intelligent device for underwater inspection of ships includes underwater equipment for underwater inspection operations, a placement module installed inside the ship for placing the underwater equipment, a release module for driving the underwater equipment in the placement module to descend underwater for underwater inspection operations, a recovery module for retrieving the underwater equipment from underwater operations back into the placement module, and a control module installed on the ship body for sending operation commands to the placement module and the release module respectively.

[0028] The control module includes a remote control system for receiving operation instructions from a remote terminal, a GPS locator installed on each underwater device to obtain the location information of the underwater device and further send the location information to the remote terminal, a status monitoring unit for receiving the location information of the underwater device to determine the completion status of the underwater device release operation, and a signal transmission module for transmitting instructions to the electrical devices of the placement module and the release module through wireless data transmission.

[0029] The placement module includes a storage compartment located inside the vessel, a release chamber located at the bottom of the storage compartment and communicating with it, a closed door that provides airtight isolation between the storage compartment and the release chamber, a communication channel communicating with the bottom of the release chamber and penetrating the bottom wall of the vessel to communicate with the outside of the vessel, a fixed base plate movably horizontally disposed within the storage compartment and / or the release chamber, and at least one corresponding top fixed to the top wall of the storage compartment via a corresponding mounting seat and a corresponding bottom connected and fixed to the fixed base plate for driving the fixed base plate to rise. The system includes a telescopic drive motor for downward movement, a closed groove continuously arranged along the side plate of the fixed base plate, an annular airbag continuously laid on the bottom wall of the closed groove, a ventilation pipe embedded inside the fixed base plate and having one end penetrating through the groove wall of the closed groove to airtightly communicate with the annular airbag, an inflation / deflation pump connected to the other end of the ventilation pipe for controlling the inflation / deflation of the annular airbag, and a cooperating door for controlling the communication between the communication channel and the outside of the ship. The closed door and the cooperating door are existing automatic closing hatches, which will not be described in detail here.

[0030] Furthermore, the annular airbag is configured such that, when in the deflated state, the annular airbag is housed and contained within the closed groove, and when in the inflated state, the annular airbag expands and extends at least partially beyond the closed groove to further abut against the side wall of the storage chamber and / or release chamber, and the annular airbag is closed and fitted within the closed groove, thereby ensuring an airtight fit between the fixed base plate and the side wall of the storage chamber when the annular airbag is in the inflated state.

[0031] The present invention uses the airbag strip to work in an airtight fit with the side wall of the storage chamber and / or release chamber to isolate the water ingress area in the release chamber from the storage chamber until the recovery module discharges the water in the release chamber, thereby ensuring the safety of underwater equipment and other electrical equipment placed in the storage chamber.

[0032] Example 2: Combined with Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 In addition to the content included in the above embodiments, it also includes:

[0033] The release module includes a transmission rod horizontally disposed on the bottom wall of the fixed base plate, a traction rope with one end fixed to the outer wall of the transmission rod and wound around the outer wall in sequence, a spiral groove continuously disposed on the outer wall of the transmission rod for orderly winding of the traction rope, a fixed shell for sleeved and fixed to the outside of the underwater equipment, a locking member for fixedly connecting the release end of the traction rope to the fixed shell, at least two bearing seats for movably fixing the transmission rod to the fixed base plate, an external gear sleeved on the outer wall of the transmission rod, a retraction drive mechanism that meshes with the external gear and drives the transmission rod to rotate synchronously by driving the rotation of the external gear, a directional drive mechanism for clamping the fixed shell in the release chamber and further driving the fixed shell to move to the communication channel, and a drive mechanism for driving the fixed shell located in the communication channel out of the communication channel to the underwater area of ​​the ship.

[0034] The directional movement mechanism includes at least two telescopic drive devices symmetrically fixed to the bottom wall of the fixed base plate for vertical telescopic operation, an electric telescopic component with one end horizontally connected to the bottom telescopic end of the telescopic drive device for horizontal telescopic operation, a clamping groove disposed on the outer wall of the fixed shell near its top, and a clamping piece fixedly connected to the other end of the electric telescopic component to penetrate and abut against the clamping groove. The clamping piece is configured as an arc-shaped structure that engages with at least part of the clamping groove, and the clamping pieces fixed to the non-transparent telescopic rod are configured to clamp the opposite ends fixed to the clamping groove, thereby achieving the clamping and fixing operation of the fixed shell through the two clamping pieces.

[0035] Then, the electric telescopic component connected to different telescopic drive devices drives the clamping piece to extend horizontally and clamp it to the opposite ends of the clamping groove to achieve the fixing operation of the fixed shell. Furthermore, the release operation of the fixed shell by the retraction drive mechanism and the synchronous vertical extension operation of the telescopic drive device are used to move the fixed shell to the communicating channel.

[0036] The retraction and extension drive mechanism includes an opening groove recessed from the bottom wall of the fixed base plate and extending upward therefrom; a drive chamber disposed inside the fixed base plate and isolated from the opening groove; a rotating rod rotatably mounted horizontally in the opening groove via a bearing mounting seat; transmission teeth sleeved on the outer rod wall of the rotating rod and meshing with the external gear; a communication port connecting the drive chamber and the opening groove; a drive motor installed inside the drive chamber and corresponding to a power output shaft passing through the communication port to be fixedly connected to one end of the rotating rod to drive the rotating rod to rotate; and at least one airtight bearing component whose corresponding outer ring is sealed on the inner wall of the communication port and whose corresponding inner ring is airtightly sleeved on the outer shaft wall of the power output shaft.

[0037] Furthermore, the airtight bearing component enables the drive chamber and the opening groove to be isolated from each other. At the same time, the power output shaft passing through the communication port enables the rotation drive of the transmission roller, preventing water entering the release chamber from entering the drive chamber through the opening groove, thereby improving the service life of the drive motor.

[0038] Example 3: Combined with Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 In addition to the content included in the above embodiments, it also includes:

[0039] The traction rope has a hollow structure inside, and the hollow structure inside the traction rope is the hollow cavity of the traction rope. The driving mechanism includes an inflatable airbag strip sleeved to the hollow cavity of the traction rope, an inflation port provided on the airbag strip, an inflation tube at least partially embedded in the transmission rod and one end of which passes through the transmission rod and the hollow cavity and is further connected to the inflation port, an inflation pump connected to the other end of the inflation tube for inflating the airbag strip, an exhaust branch pipe located in the storage chamber and one end of which is connected to the side wall of the inflation tube, an exhaust pump connected to the exhaust branch pipe, a first electrically controlled valve for controlling the connection between the inflation tube and the inflation pump, and a second electrically controlled valve for controlling the connection between the exhaust branch pipe and the inflation tube. One end of the inflation tube passes through the rotating rod and then further through the fixed base plate to extend into the storage chamber, and the other end of the inflation tube is connected to the inflation pump.

[0040] Wherein, one end fixed to the transmission rod is the fixed end of the traction rope, the other end of the traction rope is the release end of the traction rope, at least a portion of the outer sheath of one end of the airbag strip is fixed to the hollow cavity wall near the fixed end, and the one end is the first end of the airbag strip, and at least a portion of the outer sheath of the other end of the airbag strip is fixed to the hollow cavity wall near the release end, and the other end is the second end of the airbag strip.

[0041] The inflation tube extends into the air bladder cavity of the air bladder strip by passing through the fixed end of the traction rope and the first end of the air bladder strip. The end of the inflation tube that penetrates into the air bladder strip is the air outlet end of the inflation tube, and the end of the inflation tube that is connected to the air pump is the air inlet end of the inflation tube. At least a portion of the outer wall of the inflation tube is bonded and fixed to the wall of the air bladder cavity of the air bladder strip, and the air outlet end of the inflation tube is fixed to the second end. Thus, when the air pump inflates the inflation tube, the gas flows to the vicinity of the second end of the air bladder strip first. The inflation tube is a conventional flexible metal pipe, and the traction rope is wound evenly around the transmission rod in a spiral shape so that the inflation tube does not fold and can deliver gas to the air bladder strip in subsequent processes.

[0042] The airbag strip is configured such that the traction rope can move through the connecting channel when its upper limit inflation volume corresponds to the state of the airbag strip. During the inflation of the airbag strip, the inflation of the airbag strip causes the traction rope to gradually harden from its release end to its fixed end, so that the release end of the airbag strip moves outward of the connecting channel in sequence. At the same time, it effectively prevents the traction rope released from the drive rod from folding and coiling in the release cavity, so that the underwater equipment cannot be driven out of the connecting channel, and realizes the goal of driving the fixed shell out of the connecting channel to a preset underwater distance.

[0043] The operation process of the drive mechanism is as follows: when the release module releases the release end of the traction rope and the directional drive mechanism drives the fixed shell to move toward the connecting channel, the air pump inputs gas into the inflation tube, and then the gas enters the second end of the airbag strip along the inflation tube and inflates the airbag strip released to the outside of the drive rod from the second end in sequence.

[0044] The recovery module includes a drain port located on the inner wall of the release chamber, a drain pipe with one end connected to the drain port and the other end extending through to the hull of the vessel, a solenoid valve controlling the closure of the drain port, a drain pump driving the liquid in the release chamber to be discharged from the drain pipe to the outside of the vessel, a shearing device located in the connecting channel for cutting the tow rope located in the connecting channel, a floating airbag embedded in the fixed hull, and an inflation device embedded in the fixed hull for inflating the floating airbag to make the fixed hull and the underwater equipment fixed to the fixed hull float to the surface of the water. The shearing device is prior art and will not be described in detail here.

[0045] Through the shearing operation of the shearing device, the traction rope disconnects from the fixed shell and underwater equipment, allowing the underwater equipment to sink to a deeper water level for bottom inspection. With the gate closed, the solenoid valve opens and the drainage pump operates to drain the water from the release chamber through the drainage pipe, thereby ensuring the dryness of the release chamber and storage compartment and protecting the electrical equipment placed therein.

[0046] This invention uses a transmission roller to release the traction rope and a drive mechanism to move the fixed shell, thereby driving the underwater equipment from the communication channel to the underwater surface of the ship. This allows the fixed shell and the underwater equipment it holds to be driven to a predetermined depth in the water for underwater inspection operations. Based on the depth of the underwater equipment for inspection operations, the traction rope is used to pull the underwater equipment to the predetermined depth for inspection. Furthermore, the shearing device can be used to deploy the underwater equipment to deeper waters for long-term inspection operations. Based on the position information of the fixed shell, the fixed shell floating on the water surface can be directionally searched and retrieved, thus effectively improving the efficiency of underwater equipment deployment.

[0047] While the invention has been described above with reference to various embodiments, it should be understood that many changes and modifications can be made without departing from the scope of the invention. That is, the methods, systems, and devices discussed above are examples. Various configurations can be appropriately omitted, substituted, or added to various processes or components. For example, in alternative configurations, methods can be performed in a different order than described, and / or various components can be added, omitted, and / or combined. Moreover, features described with respect to certain configurations can be combined in various other configurations, such as different aspects and elements of the configuration can be combined in a similar manner. Furthermore, the elements therein can be updated as the technology develops; many elements are examples and do not limit the scope of this disclosure or the claims. It should also be understood that after reading the description of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent changes and modifications also fall within the scope defined by the claims of this invention.
