Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0036] The following combination Figures 1-10 The present invention is described as follows: a liquid carrying tank for a fire truck according to an embodiment of the present invention.

[0037] The embodiment of the first aspect of the present utility model provides a liquid-carrying tank for a fire truck, such as Figures 1 to 6 As shown, the liquid-carrying tank for a fire truck includes a tank body 100 and a mounting assembly 200 disposed below the tank body 100 .

[0038] Among them, the bottom of the tank body 100 has a first bottom plate 110 and a second bottom plate 120 connected to each other, and the height of the second bottom plate 120 gradually increases from the end connected to the first bottom plate 110 to the end away from the first bottom plate 110, and the lower surface of the second bottom plate 120 has a rib plate 130; the installation component 200 is located below the second bottom plate 120, and the installation component 200 includes a sealing plate 210 arranged in a horizontal direction and a connecting plate 220 arranged on the sealing plate 210, and the connecting plate 220 and the rib plate 130 are mechanically connected.

[0039] It should be noted that the lowest drain outlet of the tank body 100 is located at the first bottom plate 110, and the height of the second bottom plate 120 gradually increases from the end connected to the first bottom plate 110 to the end away from the first bottom plate 110, so that the second bottom plate 120 is arranged at an angle relative to the first bottom plate 110, and the second bottom plate 120 plays a water-guiding role. At the same time, the inclined second bottom plate 120 makes the overall water pressure of the bottom surface have good structural bearing capacity of the tank body 100.

[0040] It is understandable that when the bottom of the tank body 100 is welded to an external structure such as a panel, since the second bottom plate 120 is arranged upwardly and tilted relative to the first bottom plate 110, the space at the welding position between the second bottom plate 120 and the panel is small and cannot be welded. The traditional welding method avoids the welding position with such a small space, that is, the second bottom plate 120 is not welded to the panel, so the overall welding strength is low. However, the present application arranges the installation assembly 200 at the welding position of the second bottom plate 120. The installation assembly 200 includes a sealing plate 210 arranged in a horizontal direction and a connecting plate 220 provided on the sealing plate 210, and a rib plate 130 is provided on the lower surface of the second bottom plate 120. By mechanically connecting the connecting plate 220 and the rib plate 130, the sealing plate 210 can be connected to the second bottom plate 120, so that the sealing plate 210 connected to the second bottom plate 120 can be welded to the panel, thereby achieving the connection between the second bottom plate 120 and the panel to enhance the overall structural strength.

[0041] The liquid-carrying tank body for a fire truck provided by an embodiment of the present invention is provided with a rib plate 130 through the second bottom plate 120 of the tank body 100, and a connecting plate 220 is provided on the sealing plate 210 located below the second bottom plate 120. Through the mechanical connection between the connecting plate 220 and the rib plate 130, the second bottom plate 120 at the bottom of the tank body 100 and the sealing plate 210 can be fixedly connected, so that the sealing plate 210 serves as the welding surface of the second bottom plate 120 for welding, thereby enhancing the overall structural strength.

[0042] According to the embodiment of the present invention, the connecting plate 220 and the sealing plate 210 are connected and fixed by welding, and the second bottom plate 120 and the rib plate 130 are also connected and fixed by welding.

[0043] It is understood that the connecting plate 220 and the sealing plate 210 are first welded, and the second bottom plate 120 and the rib plate 130 are welded. After the welding is completed, the connecting plate 220 and the rib plate 130 are mechanically connected, so that the second bottom plate 120, the rib plate 130, the connecting plate 220 and the sealing plate 210 are connected into an integral structure. The sealing plate 210 of the integral structure avoids the confined space below the second bottom plate 120, thereby providing a welding position with other components, thereby achieving the welding of the second bottom plate 120. It should be noted here that if the tank body 100 is made of non-metallic material, such as PP composite material, the above-mentioned welding method can be a hot melt method.

[0044] It should be noted that the position space of the second bottom plate 120 at the bottom of the tank body 100 is limited and cannot be welded; this embodiment adopts a split welding design, arranges the installation component 200 at the dead corner of the second bottom plate 120 where welding is impossible, and adopts a mechanical connection method to replace the welding fixation here. In this way, the problem of being unable to weld is solved and the installation accuracy is improved. The mechanical connection combined with the welding method reduces the welding deformation of the entire plate. Therefore, this embodiment ensures strength while reducing the welding amount, the welding deformation is small, and the dimensional accuracy of the tank body 100 is further improved.

[0045] In one embodiment of the present invention, Figure 5 As shown, the second bottom plate 120 is an inclined plate. The bottom of the tank body 100 has two second bottom plates 120 , which are respectively located on opposite sides of the first bottom plate 110 . There is a mounting assembly 200 under each second bottom plate 120 .

[0046] Optionally, the lower surface of the second bottom plate 120 has a plurality of ribs 130 arranged side by side, and the sealing plate 210 is connected to a plurality of connecting plates 220 , the number of the connecting plates 220 is equal to the number of the ribs 130 , and the positions correspond one to one.

[0047] For example, the sealing plate 210 is provided with a positioning groove (not shown in the figure), and the connecting plate 220 is provided with a positioning block that cooperates with the positioning groove to achieve the position of the connecting plate 220 on the sealing plate 210. It should be noted that the number of positioning grooves, positioning blocks, connecting plates 220 and rib plates 130 is equal and their positions are corresponding.

[0048] Preferably, Figure 3 and Figure 5 As shown, the lower surface of the second bottom plate 120 has a plurality of evenly distributed ribs 130 .

[0049] In one embodiment of the present invention, the mechanical connection between the connecting plate 220 and the rib plate 130 can be: Figure 5 and Figure 6 As shown, the rib plate 130 is provided with a first connection hole 131 , and the connection plate 220 is provided with a second connection hole 221 that matches the first connection hole 131 . The first connection hole 131 and the second connection hole 221 are connected by a connecting piece.

[0050] Alternatively, the connecting member may be a bolt, and the first connecting hole 131 and the second connecting hole 221 may be threaded holes, which are connected to the first connecting hole 131 and the second connecting hole 221 by bolts to achieve a fixed connection between the connecting plate 220 and the rib plate 130. Preferably, the rib plate 130 is provided with a plurality of first connecting holes, and the connecting plate 220 is provided with a corresponding plurality of second connecting holes 221, to improve the stability of the mechanical connection between the connecting plate 220 and the rib plate 130.

[0051] Further, such as Figure 2 and Figure 8 As shown, the sealing plate 210 is provided with a mounting hole 211 corresponding to the connecting piece, and the mounting hole 211 provides a space for placing an installation tool. The installation tool is set in the mounting hole 211, and one end of the installation tool is clamped on the connecting piece. The other end of the installation tool is manipulated to rotate around the connecting piece to realize the rotation of the connecting piece, thereby connecting the connecting plate 220 and the rib plate 130 through the connecting piece, or the connecting piece disassembles the connection between the connecting plate 220 and the rib plate 130.

[0052] It is understandable that the mounting holes 211 on the sealing plate 210 facilitate the connection and detachment of the connecting member to the connecting plate 220 and the rib plate 130 .

[0053] For example, the mounting hole 211 may be an elongated hole extending in a direction perpendicular to the axis of the connector to provide a rotation space for the mounting tool.

[0054] In an optional embodiment of the present invention, there is a gap between the sealing plate 210 and the second bottom plate 120 , thereby forming a mounting gap 230 therebetween.

[0055] It can be understood that the connecting plate 220 and the rib plate 130 are connected by bolts, and nuts are connected to the bolts. Then, an installation tool is passed through the installation notch 230 to clamp the nut, and another installation tool is passed through the installation hole 211 to clamp the head of the bolt. By manipulating the installation tool to rotate, the bolt is rotated to achieve the connection and detachment of the connecting plate 220 and the rib plate 130.

[0056] In one embodiment of the present invention, Figure 3 and Figure 7As shown, one end of the rib plate 130 has a first positioning portion 132 extending toward the first base plate 110. The first positioning portion 132 is connected to the lower surface of the first base plate 110. The first positioning portion 132 and the first base plate 110 are positioned together to achieve the positioning of the installation position of the rib plate 130.

[0057] Optionally, the lower surface of the other end of the rib plate 130 has an installation slot 133, which is used to clamp the sealing plate 210. The installation position of the sealing plate 210 is positioned through the installation slot 133, thereby facilitating the positioning connection between the connecting plate 220 and the rib plate 130.

[0058] Further, such as Figure 3 and Figure 8 As shown, the sealing plate 210 has a second positioning portion 212 on one side close to the first bottom plate 110 , which is pressed against the second bottom plate 120 .

[0059] For example, the second positioning portion 212 can be an extension plate extending toward the first base plate 110. Since the second base plate 120 is a slope, the installation position of the sealing plate 210 can be positioned by the installation slot 133, and the extension plate can be pressed against the second base plate 120 to further position the installation position of the sealing plate 210.

[0060] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the tank body 100 is provided with a third positioning portion, a reinforcement 300 is provided inside the tank body 100, and the edge of the reinforcement 300 has a positioning member 310 that cooperates with the third positioning portion. Through the positioning cooperation between the third positioning portion and the positioning member 310, the tank body 100 and the reinforcement 300 are assembled and positioned, effectively ensuring the accuracy of the welding between the tank body 100 and the reinforcement 300.

[0061] For example, the third positioning portion can be a positioning groove, and the positioning member 310 can be a positioning protrusion. The tank body 100 and the reinforcement member 300 are assembled and positioned by the positioning groove and the positioning protrusion.

[0062] In one embodiment of the present invention, the third positioning portion can be a positioning hole, and the tank body 100 is provided with a positioning hole, and the reinforcement 300 is arranged in the tank body 100. The edge of the reinforcement 300 has a positioning member 310 that cooperates with the positioning hole, and the positioning member 310 has a protrusion extending out of the positioning hole, and the protrusion is welded to the positioning hole position of the tank body 100.

[0063] It can be understood that the reinforcement 300 is arranged in the tank body 100, and the edge of the reinforcement 300 has a positioning member 310 arranged in the positioning hole. The reinforcement 300 and the tank body 100 are positioned by the positioning hole and the positioning member 310. The positioning hole position on the inner surface of the tank body 100 can be welded to the reinforcement 300 to achieve the welding of the reinforcement 300 and the tank body 100; in addition, the positioning member 310 has a protrusion extending out of the positioning hole, and the protrusion can be welded to the positioning hole position on the outer surface of the tank body 100, so that the protrusion is welded to the outer surface of the tank body 100, thereby improving the connection strength between the tank body 100 and the reinforcement 300.

[0064] The liquid-carrying tank body for a fire truck provided by the present invention has a positioning hole opened in the tank body 100 and arranged on the reinforcement 300. The positioning hole and the positioning member 310 cooperate to realize the assembly and positioning of the tank body 100 and the reinforcement 300, thereby effectively ensuring the accuracy of the welding between the tank body 100 and the reinforcement 300. In addition, the positioning member 310 has a protrusion extending out of the positioning hole, which is welded to the tank body 100 through the protrusion, thereby improving the connection strength between the tank body 100 and the reinforcement 300, thereby enhancing the overall structural strength of the tank body.

[0065] Furthermore, the projection has a limiting portion that abuts against the tank body 100. Specifically, the cross-sectional area of ​​the projection is larger than the cross-sectional area of ​​the positioning hole. In this way, while the projection is welded to the tank body 100, it can abut against the outer surface of the tank body 100, limiting the torsion of the positioning member 310 and further improving the connection strength between the tank body 100 and the reinforcement member 300.

[0066] For example, the longitudinal section of the protrusion may be trapezoidal, and the bottom surface of the trapezoid is connected to the tank body 100. Of course, in other embodiments, the longitudinal section of the protrusion may also be circular, elliptical or other shapes.

[0067] It should be noted that while the connection strength between the tank body 100 and the reinforcement 300 is improved, due to the limiting effect of the protrusion, the torsion resistance is good, the overall structure is not prone to welding leaks, and has good durability, avoiding welding leaks and the problem of open welding after a period of use.

[0068] In one embodiment of the present invention, the positioning hole is formed on the top surface of the tank body 100, and the top of the reinforcement member 300 has a positioning member 310. Optionally, the top of the reinforcement member 300 has multiple positioning members 310 arranged at intervals, and the top surface of the tank body 100 has multiple positioning holes, and the number of positioning members 310 is equal to the number of positioning holes, and there is a one-to-one correspondence between them.

[0069] It can be understood that each positioning member 310 is a welding position, and the reinforcement member 300 can have multiple positioning members 310, so that multiple positioning members 310 form multiple welding positions. In this way, the reinforcement member 300 and the tank body 100 are welded through multiple welding positions, which can further improve the connection strength between the tank body 100 and the reinforcement member 300.

[0070] Optionally, there are multiple positioning holes and positioning members 310, such as Figure 4 、 Figure 5 、 Figure 9 and Figure 10 As shown, the reinforcement 300 includes a first reinforcement plate 320, and the positioning member 310 on the top of the first reinforcement plate 320 is a first positioning member 321, so the top of the first reinforcement plate 320 has multiple first positioning members 321; the top surface of the tank body 100 has multiple positioning holes, and the positioning holes on the top surface of the tank body 100 and the first positioning member 321 are matched with the first positioning holes 141, so the top surface of the tank body 100 is provided with multiple first positioning holes 141, and the multiple first positioning holes 141 are arranged at intervals along the first direction, and the multiple first positioning members 321 are matched with the multiple first positioning holes 141.

[0071] Further, such as Figure 9 As shown, the top of the first reinforcing plate 320 has a second card slot 323, and the reinforcement 300 also includes a second reinforcing plate 330. The bottom of the second reinforcing plate 330 is clamped in the second card slot 323. The positioning member 310 on the top of the second reinforcing plate 330 is a second positioning member 331, so the top of the second reinforcing plate 330 has multiple second positioning members 331; the top surface of the tank body 100 and the second positioning member 331 cooperate with the positioning hole as the second positioning hole 142, so the top surface of the tank body 100 is provided with multiple second positioning holes 142, and the multiple second positioning holes 142 are arranged at intervals along the second direction. The multiple second positioning members 331 cooperate with the multiple second positioning holes 142, and the first direction and the second direction intersect.

[0072] It can be understood that if the first positioning piece 321 on the top of the first reinforcing plate 320 is arranged along the first direction, then the first reinforcing plate 320 is arranged along the first direction; if the second positioning piece 331 on the top of the second reinforcing plate 330 is arranged along the second direction, then the second reinforcing plate 330 is arranged along the second direction; if the first direction and the second direction intersect, then the first reinforcing plate 320 and the second reinforcing plate 330 are staggered to further improve the structural strength of the tank body 100.

[0073] Preferably, the first direction and the second direction are perpendicular to each other, and the first reinforcing plates 320 and the second reinforcing plates 330 are vertically staggered, and the first positioning holes 141 and the second positioning holes 142 are staggered.

[0074] In an optional embodiment of the present invention, there are multiple first reinforcement plates 320 arranged in parallel, and there are also multiple second reinforcement plates 330 arranged in parallel. By vertically staggering multiple first reinforcement plates 320 and multiple first reinforcement plates 320, the tank body can be better reinforced to meet the use requirements of the fire truck.

[0075] In a preferred embodiment of the present invention, the reinforcement member 300 is a hollow plate. For example, the first reinforcement plate 320 and the second reinforcement plate 330 are both hollow plates, which are beneficial to reduce the obstruction to the flow of liquid or gas loaded in the tank.

[0076] Furthermore, a partition plate is provided in the tank body 100. The partition plate is a whole plate. The partition plate divides the inner cavity of the tank body 100 into multiple sealed chambers, so that different liquids can be loaded in the tank body, or other devices can be installed in the tank body.

[0077] In one embodiment of the present invention, Figure 4 、 Figure 5 and Figure 9 As shown, the tank body 100 has a support plate 150, and the first reinforcing plate 320 has a first card slot 322 that is engaged with the support plate 150. The first reinforcing plate 320 is positioned in the tank body 100 through the cooperation between the support plate 150 and the first card slot 322.

[0078] Optionally, the tank body 100 includes a bottom plate, a top plate 140 and multiple side plates, the top plate 140 is located above the bottom plate, and the multiple side plates are arranged between the bottom plate and the top plate 140 to form the inner cavity of the tank body; the support plate 150 can be arranged on the bottom plate or on the side plate. Of course, the bottom plate and the side plates can both be arranged on the support plate 150, and the first reinforcing plate 320 is correspondingly provided with a card slot.

[0079] Specifically, the bottom plate includes a first bottom plate 110 and two second bottom plates 120. The two second bottom plates 120 are respectively arranged on both sides of the first bottom plate 110 along the first direction. Therefore, the first bottom plate 110 and the second bottom plate 120 are arranged along the first direction. Since the second bottom plate 120 is arranged at an angle, the support plates 150 are preferably arranged along the second direction. When the support plates 150 are arranged on the bottom plate of the tank body 100, the support plates 150 are provided on both the first bottom plate 110 and the second bottom plate 120. The bottom surface of the first reinforcing plate 320 defines a first slot 322 corresponding to the support plates 150.
