Description
TECHNICAL FIELD
[0001] The present application relates to the field of pontoons and technologies, and particularly relates to a multipurpose pontoon. BACKGROUND
[0002] The pontoon is the main structure of a floating member on the sea, and can provide a mobile platform for large equipment such as vehicles and engineering machinery, or be used as a wave-dissipating structure of a breakwater. Due to the splicing feature, the pontoon is convenient to transport and deploy by road and railway.
[0003] However, the sea conditions in the near-shore area are complex and the wind and waves are large. Due to the influence of water depth and sea waves and other factors, it is difficult to achieve rapid splicing between the pontoons by using traditional connection methods such as bolting, which affects the splicing efficiency of the pontoons. CONTENT OF THE UTILITY MODEL
[0004] Therefore, the purpose of the present application is to provide a multipurpose pontoon to solve the above-mentioned technical problems.
[0005] In order to achieve the above purpose, the present application provides a multipurpose pontoon, which comprises:
[0006] a box body, wherein opposite sides of the box body in the length direction are respectively provided with an open slot;
[0007] an internal propulsion unit, wherein the internal propulsion unit is arranged in the box body, and part of the internal propulsion unit is exposed outside relative to the box body, so as to drive the box body to move; and
[0008] a movable connection hook and a fixed connection hook, wherein the movable connection hook and the fixed connection hook are both located in the open slot; at least one movable connection hook and at least one fixed connection hook are arranged on the opposite sides of the box body in the length direction, so that two adjacent box bodies can be detachably connected.
[0009] As can be seen from the above, the multipurpose pontoon provided by the present application can drive the pontoon to move on the water surface by applying the internal propulsion unit to the box body, thereby reducing the dependence on auxiliary equipment such as hoisting instruments, and thus reducing the splicing difficulty of the pontoon and the consumption of manpower and material resources in the splicing process. The movable connection hook and the fixed connection hook are further arranged in the open slot of the box body, so that the two adjacent pontoons can be quickly connected when they are close to each other, thereby improving the splicing efficiency of the pontoon.

[0026] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to specific embodiments and drawings.
[0027] It should be noted that, unless otherwise defined, technical terms or scientific terms used in the embodiments of the present application should be understood as their common meanings to those skilled in the art.

[0028] As a core component of offshore floating structures such as pier wharf, floating breakwater and floating pier, the pontoon is widely used in offshore operations. It can provide a stable floating platform for large equipment such as vehicles and engineering machinery, and can also serve as a wave dissipation structure in specific scenarios to reduce the impact of sea waves on nearshore facilities. The main advantage of the pontoon is its modular design, which can be freely connected to form a variety of floating structures such as floating platforms and piers. This makes the pontoon convenient to transport by road and rail, and can be quickly deployed to adapt to various construction needs.
[0029] Currently, the structure of the pontoon is relatively simple and cannot flexibly adapt to complex offshore environments. In particular, in areas with strong winds and waves, the stability of the pontoon on the sea surface is poor due to changes in water depth and the degree of sea wave fluctuation. Therefore, it is relatively difficult to implement connection using traditional methods such as bolt connection, and the firmness is relatively low, which affects the efficiency of pontoon connection and subsequent offshore operation efficiency. In addition, due to the lack of self-propulsion function of the pontoon, auxiliary tools such as lifting equipment are needed to move during the pontoon connection process, resulting in a large amount of investment in manpower and resources, thereby increasing the cost of connection.
[0030] In view of this, the present application provides a multipurpose pontoon, which combines Figures 1-8 The content of the display is described as follows:
[0031] A multi-purpose floating box comprises a box body 1, an internal propulsion unit 3, a movable connecting hook 210 and a fixed connecting hook 220; the opposite sides of the box body 1 in the length direction are respectively provided with an open slot 101; the internal propulsion unit 3 is arranged in the box body 1, and part of the internal propulsion unit 3 is exposed outside the box body 1 to drive the box body 1 to move; the movable connecting hook 210 and the fixed connecting hook 220 are both located in the open slot 101; at least one movable connecting hook 210 and at least one fixed connecting hook 220 are arranged on the opposite sides of the box body 1 in the length direction, so that two adjacent box bodies 1 can be detachably connected.
[0032] As shown in Figure 1 and Figure 2 , the box body 1 can provide mounting positions for components such as docking assemblies and internal propulsion units 3; in the length direction of the box body 1, the opposite sides of the box body 1 are respectively provided with an open slot 101, which can be used to accommodate the movable connecting hook 210 and the fixed connecting hook 220, so as to prevent the formation of a wide docking joint between two adjacent floating boxes after the docking of the movable connecting hook 210 and the fixed connecting hook 220 is completed, and to improve the firmness and delicacy of the splicing between the two floating boxes.
[0033] Exemplarily, the box body 1 can be formed of high-strength alloy steel with strong corrosion resistance, which is beneficial to improve the overall strength and service life of the floating box.
[0034] As shown in Figures 1-3 and Figure 7 , the internal propulsion unit 3 is arranged in the box body 1 and part of the internal propulsion unit 3 is exposed outside the box body 1 to provide driving force for the floating box, so as to drive the box body 1 to move and shift in water.
[0035] Exemplarily, the internal propulsion unit 3 can drive the floating box to move on the water surface, so that two floating boxes can be close to each other and spliced by the movable connecting hook 210 and the fixed connecting hook 220, which can reduce the dependence on hoisting equipment and other auxiliary equipment, is beneficial to reduce the splicing difficulty of the floating box, reduce the investment of manpower and material resources and improve the splicing efficiency.
[0036] Exemplarily, since each floating box has an internal propulsion unit 3, the floating box or the floating member formed by splicing at least two floating boxes can move on the water surface, which not only can change the position of the floating member, but also can be used to transfer personnel, instruments and articles by the carrier, so as to improve the flexibility of the application of the floating box.
[0037] As shown in Figures 1-7At least one movable connecting hook 210 and at least one fixed connecting hook 220 are arranged at opposite sides of each pontoon in the length direction of the pontoon, and are used for connecting two pontoons; more specifically, the movable connecting hook 210 and the fixed connecting hook 220 are arranged in the open slot 101, at least one movable connecting hook 210 is arranged at one side of the pontoon, and at least one fixed connecting hook 220 is arranged at the other side. When two adjacent pontoons are close to each other and the corresponding movable connecting hook 210 and fixed connecting hook 220 are connected, the movable connecting hook 210 and the fixed connecting hook 220 can be connected to each other, so as to tightly connect the two pontoons and form a connecting structure, thereby realizing quick connection between the two pontoons, reducing the difficulty of connecting the pontoons, and improving the connection efficiency.
[0038] It should be noted that, since the movable connecting hook 210 and the fixed connecting hook 220 are arranged in the open slot 101, when the movable connecting hook 210 and the fixed connecting hook 220 are connected, the open slots 101 of the two pontoons are connected to form a receiving cavity, and the connecting structure is arranged in the receiving cavity, so that the opposite side walls of the two pontoons are connected to each other, thereby reducing the connecting gap between the two pontoons, and improving the stability of the pontoon formed by the connection.
[0039] For example, the connecting structure formed by the movable connecting hook 210 and the fixed connecting hook 220 can be a Jan-type coupler, which is simple and stable, and is beneficial to quick connection and easy disassembly.
[0040] In some embodiments, as shown in Figures 3-5 The movable connecting hook 210 includes a first hook body 211, a first hook head 212, a first hook tongue 213, and a locking pin 214. The first hook body 211 is fixedly connected with the pontoon body 1, and the first hook head 212 is fixedly connected with the first hook body 211 and is supported by the first hook body 211.
[0041] The first hook head 212 is protruded with two first abutting portions 2121 in a direction away from the first hook body 211, and the two first abutting portions 2121 are embedded in the fixed connecting hook 220 when the movable connecting hook 210 is abutted with the fixed connecting hook 220, so as to ensure that the movable connecting hook 210 and the fixed connecting hook 220 are tightly attached to each other. The first hook body 211 is recessed with a movable cavity in a direction close to the first hook body 211, and the movable cavity is located between the two first abutting portions 2121, so as to provide sufficient moving space for the first hook tongue 213. The first hook tongue 213 is rotationally connected with one of the two first abutting portions 2121 and partially located in the movable cavity. When the movable connecting hook 210 is in the abutting state with the fixed connecting hook 220, the first hook tongue 213 can be embedded in the fixed connecting hook 220. Since the locking pin 214 is arranged in the first hook head 212, and the first hook tongue 213 is provided with a locking hole matched with the locking pin 214, when the locking pin 214 is inserted into the locking hole of the first hook tongue 213, the position of the first hook tongue 213 can be limited by the locking pin 214, so as to lock the first hook tongue 213 in the movable cavity and prevent the first hook tongue 213 from rotating, thereby preventing the fixed connecting hook 220 from being separated from the movable connecting hook 210, completing the abutting process of the fixed connecting hook 220 and the movable connecting hook 210, and realizing the splicing of two adjacent floating boxes.
[0042] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 6 , the fixed connecting hook 220 comprises a second hook body 221, a second hook head 222 and a second hook tongue 223. The second hook body 221 is fixedly connected with the box body 1, and the second hook head 222 is fixedly connected with the second hook body 221, so as to support the second hook head 222 by the second hook body 221.
[0043] Specifically, the second hook head 222 is protruded with two second abutting portions 2221 in a direction away from the first hook body 211, and the second hook tongue 223 is fixedly connected with one of the two second abutting portions 2221. When the movable connecting hook is in the abutting state with the fixed connecting hook 220, the two second abutting portions 2221 are embedded in the movable connecting hook 210 and matched with the two first abutting portions 2121 of the movable connecting hook 210, and the second hook tongue 223 is also embedded between the two first abutting portions 2121 and abuts against the first hook tongue 213. When the locking pin 214 of the movable connecting hook 210 locks the first hook tongue 213, the first hook tongue 213 no longer rotates and is clamped with the second hook tongue 223, thereby preventing the fixed connecting hook 220 from being separated from the movable connecting hook 210, completing the abutting process of the fixed connecting hook 220 and the movable connecting hook 210, and realizing the splicing of two adjacent floating boxes.
[0044] In some embodiments, the multipurpose floating box further comprises a driving component 4, which is arranged on the inner side wall of the open groove 101 and is arranged opposite to the upper side of the locking pin 214, so as to drive the locking pin 214 to slide along the extension direction of the lock hole.
[0045] When the two floating boxes are in the splicing state, it is not easy to operate the locking pin 214 to lock or unlock the first hook tongue 213 due to the close butt joint of the two floating boxes. Therefore, as shown in Figure 3 , the driving component 4 can be arranged in the floating box, and the driving component 4 is used to drive the locking pin 214 to move along the extension direction of the lock hole. Specifically, when the driving component 4 drives the locking pin 214 to enter the inside of the lock hole, the first hook tongue 213 can be locked by the locking pin 214, that is, the firm butt joint of the movable connecting hook 210 and the fixed connecting hook 220 is realized, so as to realize the splicing between the floating boxes. When the driving component 4 drives the locking pin 214 to exit from the lock hole, the locking effect of the locking pin 214 on the first hook tongue 213 can be released, so as to separate the movable connecting hook 210 and the fixed connecting hook 220, thereby facilitating the disassembly of the floating structure.
[0046] Exemplarily, the driving component 4 can be an electromagnetic driving component 4. When the electromagnetic driving component 4 is powered on, the electromagnetic driving component 4 is used to generate magnetic force to attract the locking pin 214, so as to suck the locking pin 214 out of the lock hole, thereby releasing the locking of the first hook tongue 213. When the electromagnetic driving component 4 is powered off, the locking pin 214 naturally falls under the gravity, so as to be inserted into the lock hole again, thereby realizing the relocking of the first hook tongue 213.
[0047] Exemplarily, the driving component 4 can be a telescopic rod, and the piston rod of the telescopic rod can be fixedly connected with the end of the locking pin 214. When the piston rod of the telescopic rod is elongated, the locking pin 214 can be inserted into the lock hole and realize the locking of the first hook tongue 213. When the piston rod of the telescopic rod is shortened, the locking pin 214 can be driven to exit from the lock hole and release the locking effect of the locking pin 214 on the first hook tongue 213.
[0048] In some embodiments, the built-in propulsion unit 3 comprises an engine 301, a pump-jet propeller 302 and an oil injection valve 303. As shown in Figure 2 and Figure 7 , the box body 1 is provided with an outer cabin 102, and the engine 301 is arranged in the outer cabin 102, which can provide a mounting position for the engine 301 and can effectively protect the engine 301.
[0049] For the pump-jet propeller 302, as shown in Figure 2 and Figure 7As shown, the pump-jet propeller 302 is in transmission connection with the engine 301, and part of the pump-jet propeller 302 is located in the box 1 and part of the pump-jet propeller 302 is exposed outside the box 1, so that the pump-jet propeller 302 is driven to operate by the engine 301 to drive the box to move on the water surface by the pump-jet propeller 302; part of the pump-jet propeller 302 is exposed outside the box 1, that is, the driving part of the pump-jet propeller 302 is exposed outside, and the box is driven to move by the driving part of the pump-jet propeller 302.
[0050] Exemplarily, the pump-jet propeller 302 can be selected according to the size of the box, the load and the power requirement, which will not be repeated here.
[0051] For the oil injection valve 303, as shown in Figure 7 , the oil injection valve 303 is arranged on the top of the box 1, and the oil injection valve 303 is in communication with the engine 301 through the oil supply pipe; by arranging the oil injection valve 303 on the top of the box 1, the oil injection valve 303 is convenient to operate to supplement fuel to the engine 301 in time.
[0052] In some embodiments, a plurality of pump-jet propellers 302 are arranged, and the plurality of pump-jet propellers 302 are distributed circumferentially along the box 1, part of each pump-jet propeller 302 is exposed outside the side wall of the box 1, and one engine 301 is in transmission connection with at least one pump-jet propeller 302 to drive the box 1 to move in different directions.
[0053] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 7 , the volume and mass of the box are relatively large, and it is difficult to change the moving direction of the box by providing a single driving force in one direction; by arranging a plurality of pump-jet propellers 302 circumferentially along the box 1, part of each pump-jet propeller 302 is exposed outside the side wall of the box 1, and the corresponding pump-jet propeller 302 can be driven to provide driving force according to different steering requirements, that is, the pump-jet propeller 302 opposite to the moving direction of the box is used to provide driving force to realize directional movement or steering of the box, which reduces the difficulty of changing the moving direction of the box and improves the flexibility of the movement of the box.
[0054] In addition, the pump-jet propellers 302 arranged on different sides can be used in combination to improve the steering efficiency, which will not be repeated here.
[0055] In addition, when one engine 301 is in transmission connection with one pump-jet propeller 302, the pump-jet propeller 302 can have strong power, and the flexibility of the distribution of the pump-jet propeller 302 on the box 1 can be improved; when one engine 301 is connected with at least two pump-jet propellers 302, the number of engines 301 can be reduced, which is conducive to reducing the manufacturing cost of the box.
[0056] In some embodiments, the box 1 is provided with a plurality of assembly grooves 103 along the circumference thereof, and a plurality of connecting holes 104 are provided through the side wall of each assembly groove 103.
[0057] As shown in Figure 1 and Figure 3 , a plurality of assembly grooves 103 are provided along the circumference of the box 1, and a plurality of connecting holes 104 are provided through the side wall of each assembly groove 103, so as to provide additional connecting positions, so that two pontoons can be spliced by fasteners such as bolts, or the completed spliced pontoons can be reinforced, further improving the firmness of the floating member; other auxiliary components can also be added to the box 1 through the connecting holes 104 and fasteners such as bolts, thereby enriching the functions of the pontoons.
[0058] In some embodiments, the multipurpose pontoon further comprises a securing plate 501 and a securing ring 502 and constitutes a securing component, which can be used to secure the pontoon to a securing position near the shore; as shown in Figure 8 , the securing plate 501 in the securing component is connected to the side wall of the box 1 through the connecting hole 104 and the fastener, and the securing ring 502 is rotationally connected with the securing plate 501.
[0059] In actual application, the securing point is provided by the securing ring 502, and the rope can be secured to the securing ring 502, and since the securing ring 502 is rotationally connected with the securing plate 501, the stretching direction of the rope can be changed, the degree of constraint between the securing ring 502 and the securing plate 501 is reduced, and the firmness of the pontoon after securing is ensured.
[0060] In some embodiments, the multipurpose pontoon further comprises a drag-reducing box 6, which is detachably connected with the box 1, so that the pontoon forms a water vehicle; since the box 1 is provided with a movable connecting hook 210 and / or a fixed connecting hook 220 on the side surface in the length direction thereof, the drag-reducing box 6 can also be provided with an open groove 101 corresponding to the movable connecting hook 210 and / or the fixed connecting hook 220 of the box 1, so as to facilitate the quick disassembly and assembly of the box 1 and the drag-reducing box 6.
[0061] More specifically, as shown in Figure 8 , the top and bottom of the drag-reducing box 6 are respectively provided with a transfer surface 601 and a drag-reducing surface 602, and the drag-reducing surface 602 is inclinedly arranged towards the direction away from the box 1; wherein the transfer surface 601 is arranged on the top of the drag-reducing box 6, which plays a role of connection, so as to facilitate the transfer of personnel, instruments or articles to the top of the pontoon through the transfer surface 601, and ensure the transfer effect; through the drag-reducing surface 602 arranged on the bottom of the drag-reducing box, the water resistance of the pontoon when moving on the water surface can be reduced, which is beneficial to reduce the energy loss in the moving process of the pontoon.
[0062] In some embodiments, a plurality of inner cabins 105 are arranged in the box 1; as shown in Figure 1As shown, by arranging multiple inner compartments 105 in the box body 1, liquid such as fresh water or fuel oil can be stored; more specifically, when the multiple inner compartments 105 are independent of each other, different liquids can be stored; and when the multiple inner compartments 105 are in communication with each other, the buoyancy tank after storing liquid will not be obviously inclined, which is beneficial to maintain the balance of the buoyancy tank and ensure the overall stability thereof.
