Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1-19, the present application provides the following technical solutions:

the inflatable boat comprises a bottom plate 1 and a boat body which is surrounded on the periphery of the bottom plate 1, wherein a fuel tank 2 is arranged above the bottom plate 1, the fuel tank 2 comprises a tank body 21, the tank body 21 is provided with an assembling part 213, the fuel tank is clamped between the boat body and the bottom plate 1 through the assembling part 213, and the fuel tank is arranged at the inner position of the head part of the boat body; in the mounted state, the fitting portion 213 thereof is located on the side of the fuel tank 2 facing the hull head. The tank 21 is provided with a cavity for storing fuel therein.

The fuel tank 2 in this embodiment is mainly used for containing fuel of fuel oil in accordance with the current common engine fuel as a reference. If there is new fuel, such as ethanol or other liquid fuel, it can be changed and used according to the material. The mode of placing the tank body 21 in the hull when the fuel tank 2 is used is adopted in the scheme, the fuel tank 2 is clamped between the bottom plate 1 and the hull, the fuel tank 2 is placed in the bow position, the assembly part 213 of the fuel tank 2 is clamped with the inner side of the bow, that is, the assembly part 213 of the fuel tank is attached to the arc-shaped protruding surface of the hull pontoon in the hull. On the one hand, the tank body 21 occupies extra space in the hull, and on the other hand, the combination degree of the tank body 21 and the inner side of the hull can be enhanced, and the stability of fixing the fuel tank 2 is improved. Through the arrangement of the attaching part and the matching of external fasteners, the fuel tank 2 can be stably fixed at the front end position inside the boat, so that the rescue space in the boat is saved; meanwhile, the device is arranged at the head of the boat, so that the stability of the gravity center in the running of the boat body is facilitated in fire rescue.

On the basis of the above-mentioned aspects, the embodiments of the present application provide a specific implementation of the attaching portion, and for convenience of description, reference will be made hereinafter to the use state of the fuel tank 2 in the hull. The attaching portion of the fuel tank 2 is provided as an arc surface, the attaching portion extends in the vertical direction, and the recess direction of the arc surface is recessed toward the inside of the tank body 21.

In a specific use, the side of the hull of the inflatable boat is usually provided with a pontoon structure, and the side of the pontoon structure facing the inner side of the hull is an arc surface, so that in order to make the installation of the fuel tank 2 more stable, the attaching part is an arc surface, and can be attached to the pontoon better, so that the fuel tank 2 is firmly clamped between the hull and the bottom of the boat. In the embodiment, a structure of the case 21 is shown in the drawings, and in a specific implementation, the case 21 may be made into a plurality of other different structures, and in this case, the attaching portion may be attached to an external device in a use state with respect to the case 21 itself, that is, the attaching portion may be attached to a pontoon of a hull.

It should be noted that, after the fuel tank 2 is clamped to the boat, the fuel tank 2 may be further fixed by ropes outside the fuel tank 2 in order to increase the stability of the fixation of the fuel tank 2. The fuel tank 2 may be further secured by other flexible connectors.

On the basis of the above-mentioned aspects, embodiments of the present application provide a specific implementation manner of the attaching portion, where the attaching portion includes a first attaching portion 2131, and the first attaching portion 2131 extends along a vertical direction and is disposed on a side portion of the case 21. For inflatable boats, the inner side structure of the bow part of the boat body has various different states according to different designs. One of them is that the inner side area closest to the bow is a shorter transverse pontoon, and two oblique pontoons are distributed in an splayed shape on two sides of the transverse pontoon. In this structural scheme, the first attaching portion 2131 is provided with an arc surface corresponding to the transverse pontoon area, and is attached to the position. Namely the first fitting part 2131 shown in the drawings of the present application.

On the basis of the scheme, considering that the tank body 21 of the fuel tank 2 and the front end of the ship body can be better combined, and the volume inside the tank body 21 is increased as much as possible, the whole volume of the tank body 21 can be increased, and two sides of the tank body can be respectively attached to the inclined pontoons distributed in the shape of the eight. Therefore, the attaching portion further includes the second attaching portion 2132, the second attaching portion 2132 also extends in the vertical direction, and one or two second attaching portions 2132 are provided on both lateral sides of the first attaching portion 2131, and the two second attaching portions 2132 extend in the direction contacting with the external device, respectively, as exemplified by the structure of the two second attaching portions 2132 in the drawings of the present embodiment.

Through this structural style, can make box 21 and the inside front end department of hull better laminate together, utilize the structural feature of hull front end to combine first laminating portion 2131 and second laminating portion 2132 to form the contact of three face and have certain centre gripping effect. While this part of the space of the bow is very suitable as a place for the fuel tank 2, where little personnel are located in use.

Based on the scheme, as before, the design of the boat has the characteristic of diversification, and the consideration that the internal design of the boat does not adopt the shorter transverse pontoon structure, but is internally provided with a herringbone-like tip, and the tip position extends obliquely towards the stern direction. In view of this, the present embodiment proposes another implementation form. The number of the first attaching parts 2131 is two, and the first attaching parts are sequentially arranged along the transverse direction of the box body 21; the connecting line of the first attaching portion 2131 is a central symmetry line of the attaching portion; one side of the first bonding portion 2131 away from the central symmetry line is correspondingly connected to the second bonding portion 2132. Two first fitting portions 2131 are combined as an adaptation scheme for the design of the inner tip of the hull. Then, according to the actual structural form of the boat, the second fitting portions 2132 may be further attached to the lateral sides of the two first fitting portions 2131.

On the basis of the above-mentioned scheme, when the pontoon structure inside the bow is arranged in a herringbone manner, the structure is similar to the structure of the application shown in fig. 1 and 2. The fitting portion structure of the fitting portion 213 of the tank 2 toward the bow direction side may be set such that the arc thereof satisfies both the vertical and lateral directions. In this state, the fitting portion 213 and the inner tip position of the bow float structure leave a buffer space in which the float tip portion inside the bow and the fitting portion 213 of the fuel tank 2 are not fitted. This damping space can to some extent attenuate the oscillations of the bow and then transmit them to the fuel tank 2.

On the basis of the above-described aspects, referring to fig. 3 and 10, the present embodiment also gives an improved way about the structure of the fuel tank 2 for discharging fuel. An oil outlet assembly 23 is arranged on the outer side of the tank body 21, the oil outlet assembly 23 comprises an oil outlet nozzle 231 and an oil outlet nozzle mounting piece 232, the oil outlet nozzle mounting piece 232 is provided with a through hole, and the oil outlet nozzle mounting piece 232 is communicated with the inside of the tank body 21 through the through hole. In the use state, the oil nozzle 231 faces the lateral direction of the tank body 21 or any direction below the lateral direction, including obliquely and vertically downward.

Considering the distribution setting mode of the oil pipe inside the actual boat, the oil pipe pipeline is arranged on the horizontal height of the position of the attached bottom of the boat reasonably for safety and convenient hiding. Therefore, the nozzle 231 is designed to be at a downward angle in a horizontal direction or outside the horizontal direction, so that the bending degree of the oil pipe can be reduced when the nozzle is connected with the oil pipe, on one hand, the oil is discharged more smoothly, and on the other hand, the service life of the oil pipe at the joint of the nozzle 231 can be prolonged.

On the basis of the scheme, the scheme also provides an improvement scheme for the installation joint of the tank body 21 and the oil outlet assembly 23. The oil discharging assembly 23 is arranged at the upper area outside the box body 21, and an oil discharging assembly mounting part 215 which is inclined downwards is arranged on the box body 21; the oil discharge unit 23 is provided in the oil discharge unit mounting portion 215. For the same reason as that considered in the foregoing, in order to allow the oil pipe to be better connected to the oil spout 231, the present embodiment adjusts the orientation of the entire oil discharging assembly 23 to be inclined by improving the outer wall structure of the fuel tank 2 on the basis of the adjustment of the direction structure of the oil spout 231 itself. It should be noted that the slant of the present embodiment and the slant adjustment of the nozzle tip are not on the same plane, but as shown in fig. 10, the oil discharging assembly mounting portion 215 is inclined toward a direction away from the mounting portion 213, that is, the lower end of the oil discharging assembly mounting portion 215 is inclined toward the stern end away from the bow. And the inclination direction of the aforementioned nozzle 231 corresponds to the lateral direction of the hull. By combining the inclination angles of the two embodiments, the bending degree of the oil pipe when the oil pipe is connected to the oil outlet nozzle 231 can be further reduced, so that the oil pipe can be smoothly connected with the oil outlet nozzle 231.

In addition to the above, as a further improvement, the oil discharge assembly mounting portion 215 includes a mounting plate extending obliquely downward toward the bottom of the tank. As shown in fig. 10, a slope is provided on the upper side wall of the fuel tank 2 as the oil delivery module mounting portion 215, so as to secure the position and the combination of the oil delivery module 23. The inclined surface is added with a plate body structure, namely the assembly of the mounting plate in the scheme, and the mounting plate is attached to the inclined surface of the box body 21, so that a good mounting joint is provided for the oil assembly 23.

On the basis of the above scheme, referring to fig. 3 to 9, the upper end of the box body 21 is a box top 212, and the present embodiment also provides an improvement scheme about the box top 212; arranging the roof 212 in a stepped configuration; the oil inlet of the box body 21 is arranged at a low horizontal position of the stepped structure of the box top 212; the upper part of the cavity inside the tank 21 extends to a high level of the stepped structure of the tank top 212.

Because the fuel tank 2 of the present embodiment is applied to a boat, it is considered that there are many times when the fuel tank 2 needs to be filled with fuel in a state where the boat is on the water surface. The ship body can shake along with water flow in the oil filling process, the tank top 212 is arranged to be in the form of a step-shaped structure through the scheme, because fuel in the fuel tank 2 can enter the high-level position part of the tank top 212 along with shaking, and when the fuel tank 2 swings reversely, the fuel is blocked to a certain extent by the step-shaped structure, so that the possibility of overflowing of the fuel from the oil inlet position is reduced.

On the basis of the above-mentioned scheme, the stepped structure of the tank top 212 may be directed to any side of the hull, but the scheme adopts the structure shown in the drawings, that is, the high level portion of the stepped structure of the tank top 212 is disposed close to the fitting portion 213, in consideration of the aesthetic appearance and reducing the influence that the structural position may have on personnel in the ship.

On the basis of the scheme, the box cover 22 is connected with the oil inlet of the box body 21, and the height of the box cover 22 meets the upper end face of the high horizontal position of the box cover 22 which is flush with or higher than the stepped structure in the screwing state. As before, in order to reduce the energy of fuel overflowing the inlet port due to sloshing of the fuel tank 2, the inlet port is provided at a low level of the stepped structure of the tank top 212. In order to facilitate screwing of the cover 22, the present embodiment designs the cover 22 to be flush or higher with respect to a high level position so as to facilitate holding and screwing of the cover 22.

On the basis of the above scheme, as a part of the structural composition of the box 21, the box 21 further includes a connection portion 214, and the connection portion 214 is a side wall structure of the box 21 and is disposed opposite to the assembly portion 213; the lower part of the connecting part 214 is connected to the bottom 211, the upper part is connected to the top 212, and both sides of the connecting part 214 are connected to the fitting parts 213. The aforementioned oil discharging assembly 23 is disposed at an upper region of the connection portion 214.

On the basis of the above scheme, as a part of the structural composition of the box 21, the box 21 further comprises a handle 24, the handle 24 is fixedly arranged on the box top 212, a notch is formed in the middle of the high-level part of the stepped structure of the box top 212, and the handle 24 is bridged above the notch, so that the box 21 can be conveniently lifted.

In addition, the case 21 is further provided with a reinforcing structure 25, and the reinforcing structure 25 is disposed at a side portion of the case 21 for increasing the strength of the side portion of the case 21, and the function of the reinforcing structure is equivalent to that of the reinforcing rib. The specific implementation may be a transverse stiffening rib protruding from the outer surface of the casing 21 or a transverse groove as in the drawings of the present application. The grooves are distributed in a plurality of strips and are positioned on the connecting part 214, and two ends of the grooves extend to the second attaching part 2132.

The present embodiment improves the structure of the bottom plate 1 of the boat on the basis of the above embodiment, and for convenience of explanation, the following will be described with the longitudinal direction of the hull as the longitudinal direction and the width direction of the hull as the transverse direction, and the bottom plate 1 of the present embodiment includes the bottom plate body 11 extending in the longitudinal direction. The middle part of the bottom plate main body 11 is provided with a middle keel 12, the middle keel 12 also extends along the longitudinal direction, the middle keel 12 penetrates through the bottom plate main body 11, and the middle keel 12 extends to the lower part of the bottom plate main body 11.

Through this structural scheme, at the additional middle part fossil fragments 12 in bottom plate 1 middle part, the structural effect of broken water can be brought for the ship bottom to middle part fossil fragments 12. Thereby reducing the water surface retarding force on the ship bottom during the advancing process. And because the structure of the middle keel 12 is arranged, when the ship body is lifted up due to the forward movement of the ship body, the impact force on the ship head can be reduced due to the water breaking effect brought by the middle keel 12 in the falling process.

On the basis of the above embodiment, the bottom plate 1 of the present embodiment further includes a fixing member 13, and the fixing member 13 spans over the upper side of the middle keel 12; extending in a longitudinal direction; the fixing member 13 is connected to the floor main body 11 on both lateral sides.

The additional fixing member in this embodiment serves as a fixing and limiting structure for the upper side of the middle keel 12, and applies a pressing force to the portion of the middle keel 12 located on the upper side of the floor body 11 through the fixing member 13. Because this scheme is used for inflating the assault boat, so its bottom plate structure self has certain elasticity, when because the impact of rivers brings ascending strength for middle part fossil fragments 12, the mounting 13 can exert reverse downforce to improve the broken water effect that middle part fossil fragments 12 can bring.

On the basis of the above embodiment, the floor main body 11 of the present embodiment includes a first half 111 and a second half 112; the middle keel 12 is disposed between the first half 111 and the second half 112, and two sides of the middle keel 12 are fixedly connected to the first half 111 and the second half 112, respectively. As can be seen in fig. 14, the main body 11 of the base plate is formed by abutting two halves, and then the middle keel 12 is disposed between the first half 111 and the second half 112, and the first half 111 and the second half 112 are fixedly connected at positions of two ends of the middle keel 12. The advantage of this construction is that the floor body 11 is easier to manufacture and install and the connection location of the two to the middle keel 12 is easier to process.

Unlike the present embodiment, the main body 11 of the base plate may be formed integrally, and the central keel 12 is inserted into the central opening of the main body 11 of the base plate, but this solution is relatively inferior to the above solution in that it is convenient to manufacture and process, and the advantage is that the main body 11 of the base plate is integrally formed.

On the basis of the above embodiment, the floor main body 11 and the middle keel 12 are both made of air-filled wire-drawing cloth. As it is applied to inflatable assault boats. The floor body 11 and the middle joist 12 are inflatable structures. Corresponding to the previous embodiment, the first half 111 and the second half 112 are independently inflated chambers.

On the basis of the above embodiments, referring to fig. 15 to 17, as a further specific embodiment of the middle keel 12, the middle keel 12 includes an upper body 121 and a lower body 122. Wherein the upper body 121 is located at the upper side of the floor main body 11, and the upper body 121 protrudes from the upper surface of the floor main body 11; the lower body 122 is located at the lower side of the bottom plate main body 11, and the lower body 122 is in a downward protruding arc structure near the bow of the bottom plate main body 11.

The cross section of the upper body 121, i.e. the cross section in the transverse direction of the floor body 11, approximates a cylindrical structure for the upper body 121. The lateral width thereof is slightly larger than that of the lower body 122, so that it can be ensured that the lower side surface of the upper body 121 portion is abutted against the upper surface of the floor main body 11 at the time of mounting combination without excessive downward movement.

On the basis of the above embodiment, the middle keel 12 further comprises a middle body, the middle body is located between the upper body 121 and the lower body 122, two sides of the middle body are fixedly connected with the bottom plate main body 11, and the middle body is in a deformed structure with two narrowed sides relative to the upper body 121. The middle body serves as a transition structure between the upper body 121 and the lower body 122, exhibiting a "waisted" with respect to the upper body 121, so as to cause the upper body 121 to transition from an arc surface to the lower body 122.

On the basis of the above embodiment, the upper body 121 exhibits a corresponding uniform deformation structure along the upper side of the floor main body 11. Since the upper body 121 is used mainly as the force application portion of the fixing member 13 and as the mounting portion of the middle keel 12 on the upper side of the floor main body 11, the upper body 121 does not need to have a complicated structure, and it is only required to correspond to the shape of the floor main body 11, and it is possible to smoothly attach the upper body.

Based on the above embodiment, the lower body 122 of the middle keel 12 adopts the following structural scheme:

the lower body 122 protrudes downward near the bow of the bottom plate body 11, and transitions from the protruding point to the bow and stern in a gradual transition. The projection at the lowermost end of the lower body 122 transitions in an arc-like configuration in the direction of the bow. The projection at the lowermost end of the lower body 122 transitions from an arc-like configuration at the projection to a sloping configuration of the long straight body in the stern direction.

With this structural form, the lower body 122 of the middle keel 12 is used as a structural part for mainly achieving the technical effect, the whole body is similar to a blade shape, and the position close to the front end of the ship body presents a large arc-shaped structure, so that the technical effect of breaking water at the bottom plate position of the ship body is achieved. And the position close to the rear part of the ship body is gradually retracted upwards, and the whole body is in streamline design.

On the basis of the above embodiment, the fixing member 13 is made of a flexible material. The fixing piece 13 bears the upward force from the bottom of the middle keel 12 when the middle keel 12 is stressed by virtue of the flexible material and presses the upper side of the middle keel 12, and then feeds back the downward force to the middle keel 12, so that the cracking effect of the middle keel 12 on the water surface is enhanced.

On the basis of the above embodiment, the fixing member 13 includes the first fixing portion 131 and the second fixing portion 132, and the first fixing portion 131 and the second fixing portion 132 are detachably connected.

Referring to fig. 18 and 19, two specific embodiments of the present embodiment are shown in fig. 18, wherein one side of the first fixing portion 131 is fixedly connected to the base main body 11, the other side is connected to the second fixing portion 132 by a connecting buckle, and the first fixing portion 131 is covered on the upper side of the middle keel 12 by a plurality of connecting buckles distributed along the longitudinal direction.

In fig. 19, a zipper is used as an example of the connection method, and the first fixing portion 131 and the second fixing portion 132 are connected by the zipper, so that the operation is very simple and fast.

On the basis of the above embodiment, the connection of the first fixing portion 131 and the second fixing portion 132 is provided in the longitudinal direction, and the projection of the connection on the floor main body 11 is located on one side of the middle keel 12.

Because the middle keel 12 body is considered to be an inflatable structure, the connection of the first fixing portion 131 and the second fixing portion 132 is provided at one side of the upper portion of the middle keel 12, and the wear of the upper portion of the middle keel 12 due to the specific connection structure (such as a zipper) of the connection can be avoided.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present application, and the present application is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present application has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
