Description

Technical Field

[0001] The invention relates to the technical field of water rescue equipment, and in particular to a safe and stable marine rescue boat. Background Art

[0002] Sea rescue boats are key equipment in sea rescue operations, designed to ensure rapid and effective rescue of personnel in emergency situations. Sea rescue boats can be divided into open lifeboats, semi-enclosed lifeboats and fully enclosed lifeboats in terms of structure, and are used for different rescue operations in different rescue environments.

[0003] For example, after learning about the drowned object at sea, open, semi-enclosed and fully enclosed lifeboats are selected to carry out rescue work in a targeted manner to achieve the purpose of safe lifesaving. In actual rescue work, as the weight increases, the buoyancy of the sea rescue boat can be dynamically adjusted by increasing the displacement volume to maintain the balance between buoyancy and weight. The buoyancy of the sea rescue boat is determined by the weight of the water it displaces. According to Archimedes' principle, the buoyancy is equal to the weight of the water displaced. Therefore, when the overall weight of the sea rescue boat increases, in order to maintain the balance between buoyancy and weight, the sea rescue boat needs to increase the displacement volume to increase the weight of the water displaced, so that the buoyancy increases accordingly;

[0004] In combination with the above, it should be noted that: there is uncertainty about objects falling into the water at sea, which makes it impossible to make targeted intelligent rescue adjustments in a timely manner during the rescue process. There is a risk of overweight in the life-saving process where the load increase cannot be estimated, which affects the smooth rescue. For this reason, this application proposes a solution.

[0019] The present invention has the following beneficial effects:

[0020] 1. The present invention is aimed at the problem that there is uncertainty about people falling into the water at sea, which leads to the inability to make targeted intelligent rescue adjustments in time during the rescue process; the airbag structure is added to realize the dynamic adjustment of the load capacity of the overall structure of the rescue boat, so as to solve the problem that targeted rescue adjustments cannot be achieved under the premise that the static load data of the rescue boat is fixed, and the cover structure with a variable coverage area completes the surrounding adjustment of the rescue boat. Specifically, the intelligent analysis and control module is combined to complete the control of the settlement and drainage and the acquisition of the travel deflection of the rescue boat in real time during the rescue process, and the dynamic adjustment of the load capacity and the stable operation control are realized by intelligently controlling the rescue boat, so as to meet the buoyancy control of the rescue boat for the rescued persons during the rescue process and prevent the problem of overweight risk during the life-saving process;

[0021] 2. When the load increment estimate is unclear, intelligent adjustment is performed through the following actions:

[0022] Action 1: Drive the propeller blades and rudder to control the speed and direction of the boat: The propeller blades are driven to move according to the preset route and sailing speed, and the direction of travel is adjusted through the rudder to prevent the rescue boat from capsizing due to different weights on both sides after completing the sea rescue;

[0023] Action 2: The air pump component completes the inflation and deflation of the floating airbag by connecting the floating bar: The air pump component inflates and deflates the floating airbag by connecting the floating bar. When the rescued personnel are loaded in the hull, the current load is obtained according to the internal weighing sensor, and the overall buoyancy of the rescue boat is compared with the current overall load and the inflated and deflated floating airbag, and the floating airbag is inflated quickly and synchronously until the sum of the buoyancy of the floating airbag and the hull itself is greater than the current load. Then it stops. At this time, it can ensure that the rescue boat can complete stable load-bearing, and estimate the load after the rescued personnel are towed on the rescue boat, and cooperate with the inflation of the floating airbag to increase the current buoyancy, and finally avoid the capsizing accident caused by the risk of overweight;

[0024] Action three: The motor controls the coverage area of ​​the cabin cover and the electric push rod to control the immersion depth of the floating airbag through the rotating fulcrum: the motor starts to drive the frame to complete the rotation around the rotating fulcrum. At this time, the cabin cover completes bidirectional deflection driven by the frame, that is, it realizes the "full-enclosed", "half-enclosed" and "open" encirclement adjustment, so as to adapt to different living conditions and rescue environments, and improve the survival probability of the rescued personnel. It also includes that the electric push rod starts to drive the rotating frame to complete the rotation. At this time, the rotating frame drives the buoyancy plate to complete the axial rotation. The deflection of the buoyancy plate can press down the inflated floating airbag to prevent it from flipping upward after inflation and affecting the normal boarding of the rescued personnel. In addition, the drainage volume of the floating airbag can be increased during the downward pressure process, and then fine-tuning can be performed while adding floating airbags to change the load capacity, and finally the buoyancy is far greater than the load during the rescue process to ensure the safe navigation of the rescued personnel.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: In view of the uncertainty of people falling into the water at sea, it is impossible to make targeted intelligent rescue adjustments in time during the rescue process, which makes it impossible to estimate the load increment and there is a risk of overweight during the rescue process. For this purpose, the following technical solution is proposed:

[0037] Reference Figure 1 - Figure 8 As shown, in this embodiment, a safe and stable marine rescue boat comprises a hull 1 and a control panel embedded in one side of the hull 1. A cabin 3 is provided on the hull 1. A pair of side base plates 5 are installed through the rear side of the cabin 3. The side base plates 5 extend to the outside of the hull 1 and are installed with sleeve rods 6. A lifting assembly is provided on the outer side of the hull 1 corresponding to the side base plates 5. The lifting assembly comprises at least three floating air bags 4 installed outside the hull 1. A rotating frame 8 is inserted in the sleeve rod 6. A pressure floating plate 9 pressed to the top of the floating air bag 4 is installed at the swinging end of the rotating frame 8.

[0038] Reference Figure 1 , Figure 2 and Figure 4 As shown, a covering assembly is rotatably mounted on the rear side of the hull 1 corresponding to the cabin 3, and the covering assembly includes a frame 18 that is deflected by 90° in both directions through a rotating fulcrum, and a cabin cover 2 connected to the hull 1 is mounted on the rear side of the frame 18, and a driving mechanism for driving the deflection thereof is mounted on the hull 1 corresponding to the rotating fulcrum of the frame 18;

[0039] Reference Figure 3As shown, an electric push rod 14 is embedded and hinged on one side of the corresponding side base plate 5 of the hull 1, and a swing block 15 sleeved with the rotating frame 8 is rotatably installed on the output end of the electric push rod 14. A stabilizing block 16 connected to the hull 1 is installed at one end of the rotating frame 8 away from the swing block 15. The rotating frame 8 includes two longitudinal rod bodies and two transverse rod bodies connected to each other. The longitudinal rod body on the outer side is rotatably connected to the sleeve rod 6, and the longitudinal rod body on the inner side is connected to the pressure floating plate 9. The two transverse rod bodies are respectively installed at both ends of a pair of longitudinal rod bodies and abut against the pressure floating plate 9.

[0040] Reference Figure 5 and Figure 6 As shown, the driving mechanism includes a motor 12 arranged on the inner side of the hull 1, the output end of the motor 12 passes through the hull 1 and is connected to the rotating wheel 22, the motor 12 drives the rotating wheel 22 to drive the frame 18 to achieve a two-way 90° deflection with a rotating fulcrum, the motor 12 drives the frame 18 to rotate through the rotating wheel 22, and the frame 18 drives the cabin cover 2 to complete the "full-enclosed", "half-enclosed" and "open" enclosed adjustments, so as to adapt to different living conditions and rescue environments, and improve the survival probability of the rescued personnel;

[0041] Reference Figure 1 As shown, a driving blade 10 is installed at the lower middle side of the rear end of the hull 1, and a rudder plate 11 is installed at the upper end of the hull 1 close to the driving blade 10, wherein the driving blade 10 is a power component driven by a built-in motor and a reducer as a driving element, providing the driving power of the hull 1 of the entire rescue boat, and the rudder plate 11 is a control component for controlling the traveling deflection direction of the hull 1 of the rescue boat;

[0042] Reference Figure 2 , Figure 3 and Figure 7 As shown, the inner side of the floating airbag 4 is installed with a connecting floating bar 13 fixedly connected to the hull 1, and the hull 1 is embedded with an air pump component for inflating and deflation of the floating airbag 4 through the connecting floating bar 13. When adjusting the inflation and deflation of the floating airbag 4, the inflation and deflation of the floating airbags 4 at both ends of the same side are preferentially selected to ensure that they maintain a symmetrical inflation and deflation state to prevent the hull 1 of the rescue ship from capsizing. It should be noted that the rescue ship is also provided with a wind speed and direction finding component (not shown in the figure, used to provide active deflection control for the current unmanned rescue automatic navigation) to stabilize navigation.

[0043] Structural principle: The rescue boat designed by the present invention is basically consistent with the principle of the lifeboat in the prior art, and the difference in structure is that the dynamic adjustment of the overall structural load of the rescue boat is achieved through the added airbag structure, so as to solve the problem that the targeted rescue adjustment cannot be achieved under the premise of the fixed static load data of the rescue boat, and the enclosure adjustment of the rescue boat is completed by the cover structure with a variable coverage area, so as to provide targeted protection for the rescued personnel and improve their survival probability;

[0044] The control panel has a built-in control module, which includes a numerical monitoring terminal, a load risk assessment terminal and a signal execution terminal that are connected to each other;

[0045] The numerical monitoring end is used to collect the settlement and displacement value CP and the operation deflection value YP during the operation of the rescue boat, and send the settlement and displacement value CP and the operation deflection value YP to the load risk assessment end;

[0046] The load risk assessment end immediately analyzes the displacement volume and inclination data of the rescue boat based on the received settlement displacement value CP and operation deflection value YP. The specific analysis process is as follows:

[0047] The settlement drainage value CP and the operation deflection value YP within the time threshold are obtained, and the settlement drainage value CP and the operation deflection value YP are calculated according to the formula PQ = (a × CP + b × YP) / k to obtain the drainage inclination coefficient PQ, where a and b are preset proportional factor coefficients, and a>b>0, k is the preset correction factor coefficient and k>0, and the drainage inclination coefficient is compared and analyzed with the drainage inclination standard value preset by the system:

[0048] If the drainage inclination coefficient is greater than the drainage inclination standard value, a control signal is generated and sent to the signal execution end. The signal execution end controls the driving blade 10, the air pump assembly, the motor 12 and the electric push rod 14 to perform the following actions according to the received control signal:

[0049] Action 1: driving the blades 10 and the rudder 11 to control the speed and direction of the hull 1: driving the blades 10 to move according to the preset route and sailing speed, and adjusting the direction of travel through the rudder 11 to prevent the rescue boat from capsizing due to the different weights on both sides after completing the sea rescue;

[0050] Action 2: The air pump assembly completes the inflation and deflation of the floating airbag 4 by connecting the floating bar 13: The air pump assembly inflates and deflates the floating airbag 4 by connecting the floating bar 13. When the rescued personnel are loaded in the hull 1, the current load is obtained according to the internal weighing sensor, and the overall buoyancy of the rescue boat is compared with the current overall load and the inflated and deflated floating airbag 4, and the floating airbag 4 is inflated synchronously and quickly until the sum of the buoyancy of the floating airbag 4 and the hull itself is greater than the current load, and then stops. At this time, it can ensure that the rescue boat completes stable load-bearing, and the load-bearing capacity is estimated after the rescued personnel are towed onto the rescue boat, and the current buoyancy is increased in conjunction with the inflation of the floating airbag 4, and finally the capsizing accident caused by the risk of overweight is avoided;

[0051] Action three: The motor 12 controls the coverage area of ​​the cabin cover 2 and the electric push rod 14 to control the immersion depth of the floating airbag 4 through the rotating fulcrum: wherein the motor 12 starts to drive the frame 18 to complete the rotation around the rotating fulcrum, at which time the cabin cover 2 completes bidirectional deflection driven by the frame 18, that is, realizes the surrounding adjustment of "full-enclosed", "half-enclosed" and "open", so as to adapt to different living conditions and rescue environments, and improve the survival probability of the rescued personnel, and also includes that the electric push rod 14 starts to drive the rotating frame 8 to complete the rotation, at which time the rotating frame 8 drives the buoyancy plate 9 to complete the axial rotation, and the deflection of the buoyancy plate 9 can press down the inflated floating airbag 4 to prevent it from flipping upward after inflation and affecting the normal boarding of the rescued personnel, and in the process of pressing down, the drainage volume of the floating airbag 4 can be increased, and then fine-tuning can be performed while adding the floating airbag 4 to change the load capacity, and finally the buoyancy is far greater than the load capacity during the rescue process, ensuring the safe navigation of the rescued personnel;

[0052] If the drainage inclination coefficient is ≤ the drainage inclination standard value, no signal is generated.

[0053] Basic principle: Due to the uncertainty of people falling into the water at sea, it is impossible to make targeted intelligent rescue adjustments in time during the rescue process, which makes it impossible to predict the load increment and there is a risk of overweight during the rescue process. The additional airbag structure is used to dynamically adjust the load of the overall structure of the rescue boat, solving the problem that targeted rescue adjustments cannot be made under the premise of fixed static load data of the rescue boat.

[0054] The cover structure with a variable coverage area is used to complete the encirclement and adjustment of the rescue boat. Specifically, the intelligent analysis and control module is combined with the real-time status of the rescue boat during the rescue process to complete the control of settlement and drainage and the acquisition of travel deflection. The intelligent control of the rescue boat is used to realize dynamic adjustment of the load capacity and stable operation control to meet the buoyancy control of the rescue boat for the rescued persons during the rescue process and prevent the risk of overweight during the rescue process.

[0055] Example 2: Reference Figure 1 - Figure 8 As shown, the present embodiment further comprises a rotating fulcrum including a rotating seat 7 sleeved and arranged outside the sleeve rod 6, an outer ring 20 is mounted on the rotating seat 7, an inner matching wheel 23 rotatably mounted inside the outer ring 20 and connected with the inner matching wheel 23, rotating wheels 22 attached to the outside of the outer ring 20 are mounted on both sides of the inner matching wheel 23, anti-slip blocks 21 are evenly distributed on the outside of the rotating wheel 22, and a connecting block 24 fixedly connected to the end of the frame 18 is commonly mounted between the anti-slip blocks 21 on the upper side;

[0056] Reference Figure 2 and Figure 5As shown, the motor 12 can be horizontally moved and fixed along the hull 1 (not shown in the figure, a waterproof cylinder is specifically used to realize the longitudinal displacement function of the motor 12, and this technology is a mature existing technology, so no further description is made);

[0057] In this process, the rotating seat 7 can complete the longitudinal movement along the sleeve rod 6 to adjust the coverage of the cabin cover 2, that is, the position of the rotating fulcrum is changed to achieve the purpose of adjusting the surrounding area. It should be noted that all the cabin covers 2 in the drawings are in a wrinkled and curled state so as to form a normal stretching and contracting state.

[0058] Reference Figure 8 As shown, a winding sleeve 26 is installed at the lower end of the cabin cover 2, a sliding rod 25 is installed on the outer side of the hull 1 corresponding to the winding sleeve 26, the winding sleeve 26 is sleeved to the outside of the sliding rod 25, and a pull rod 17 is installed on the outer side of the upper end of the pressure buoy 9, and the pull rod 17 is a "U"-shaped structure;

[0059] When implementing the maritime rescue mission, the ship uses its own preset navigation route and intelligent obstacle avoidance system for intelligent navigation, and cooperates with the aerial search and rescue equipment to explore the location of the rescue personnel. When the rescued person is found, it immediately sails to the location and hovers, inflates the airbag 4 and lowers the buoyancy plate 9, so that the pull rod 17 on the buoyancy plate 9 can approach the rescued person, and then the rescue personnel on the rescue ship help the person who fell into the water to get on board;

[0060] The electric push rod 14 is immediately started, and the electric push rod 14 drives the rotating frame 8 to complete the rotation. At this time, the rotating frame 8 drives the buoyancy plate 9 to complete the axial rotation. The deflection of the buoyancy plate 9 can press down the inflated floating air bag 4 to prevent it from turning upward after inflation and affecting the normal boarding of the rescued personnel. In addition, the drainage volume of the floating air bag 4 can be increased during the pressing process. While adding the floating air bag 4 to change the load capacity, fine-tuning can be performed, and finally the buoyancy is made much greater than the load during the rescue process, ensuring the safe navigation of the rescued personnel.

[0061] Example 3: Reference Figure 1 - Figure 8 As shown, this embodiment combines the technical contents of the first embodiment and the second embodiment to form the following rescue method:

[0062] Step 1: When the rescue boat is carrying out the maritime rescue mission, it uses its own preset navigation route and intelligent obstacle avoidance system for intelligent navigation, and cooperates with the aerial search and rescue equipment to explore the location of the rescue personnel. When the rescued person is found, it immediately sails to the location and hovers, inflates the airbag 4 and lowers the buoyancy plate 9, so that the pull rod 17 on the buoyancy plate 9 can approach the rescued person, and then the rescue personnel on the rescue boat help the drowned person to get on board;

[0063] Step 2: After boarding the ship, the current load is obtained according to the internal weighing sensor, and the overall buoyancy of the rescue ship is compared with the current overall load and the floating airbag 4 after inflation and deflation, and the floating airbag 4 is inflated quickly and synchronously until the sum of the buoyancy of the floating airbag 4 and the hull itself is greater than the current load. Then stop, at this time, it can ensure that the rescue ship completes stable load-bearing, and the load is estimated after the rescued personnel are towed onto the rescue ship, and the current buoyancy is increased in conjunction with the inflation of the floating airbag 4, and finally avoid the capsizing accident caused by the risk of overweight;

[0064] Step 3: In step 2, according to the survival status of the rescued person, the current encirclement form is adjusted, specifically, the motor 12 is started to drive the frame 18 to complete the rotation around the rotation fulcrum, and the cabin cover 2 is driven by the frame 18 to complete the bidirectional deflection, that is, the encirclement adjustment of "full encirclement", "half encirclement" and "open" is realized, so as to adapt to different survival conditions and rescue environments, and improve the survival probability of the rescued person;

[0065] Step 4: Simultaneously with step 3, the electric push rod 14 is started to drive the rotating frame 8 to complete the rotation. At this time, the rotating frame 8 drives the buoyancy plate 9 to complete the axial rotation. The deflection of the buoyancy plate 9 can press down the inflated floating airbag 4, thereby preventing it from flipping upward after inflation and affecting the normal boarding of the rescued personnel. In addition, the drainage volume of the floating airbag 4 can be increased during the pressing process, and then fine-tuning can be performed while adding the floating airbag 4 to change the load capacity, ultimately achieving the goal of making the buoyancy much greater than the load during the rescue process, ensuring the safe navigation of the rescued personnel.

[0066] In summary: the present invention realizes dynamic adjustment of the load capacity of the overall structure of the rescue boat through the added airbag structure, and achieves targeted rescue adjustment under the premise that the static load data of the rescue boat is fixed, and the encirclement adjustment of the rescue boat is completed by the cover structure with a variable coverage area. Specifically, the real-time status of the rescue boat during the rescue process is combined with the intelligent analysis and control module to complete the control of sedimentation and drainage and the acquisition of travel deflection, and the dynamic adjustment of the load capacity and stable operation control are realized through the intelligent control of the rescue boat, so as to meet the buoyancy control of the rescue boat for the rescued persons during the rescue process and prevent the risk of overweight during the life-saving process.
