Detailed Implementation

[0025] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figure 1 , 2As shown in Figures 4 and 5, in a first aspect, embodiments of this application provide a water tank structure for a fire truck, including a longitudinally elongated body 1. The top of the body 1 is used to place a fire-fighting drone 2, thereby improving the overall space utilization of the fire truck. A first partition 3 is provided inside the body 1, extending along the length of the body 1. The first partition 3 divides the body 1 into two chambers, a water storage chamber 11 and a foam chamber 12. The upper end face of the body 1 is also provided with two inspection ports that are respectively connected to the water storage chamber 11 and the foam chamber 12. The two inspection ports are close to the rear end of the body 1. In this way, the drone 2 above the body 1 will have less impact on maintenance personnel. Compared with the inspection ports being located at the front or middle, the drone 2 above the body 1 will affect the maintenance personnel's access to the inspection ports in the vertical direction. The water tank structure of this application embodiment will be more convenient for maintenance personnel to perform maintenance.

[0028] Optionally, the two ends of the first partition 3 can be connected to the two side walls in the width direction of the box 1 respectively. The first partition 3 can divide the box 1 into a water storage cavity 11 and a foam cavity 12 with the same volume. Of course, the first partition 3 can also be offset from the position of the central axis in the longitudinal direction of the box 1, that is, the volume of the water storage cavity 11 can be larger than the volume of the foam cavity 12, or the volume of the foam cavity 12 can be larger than the volume of the water storage cavity 11.

[0029] Optionally, the front end of the box 1 refers to the end where the fire truck cab is located, and the rear end is the end located behind the cab.

[0030] Optionally, the length direction of the box 1 refers to the forward direction of the fire truck, and the width direction refers to the left and right sides of the fire truck.

[0031] like Figure 1 As shown, optionally, both the water storage chamber 11 and the foam chamber 12 are provided with a drain pipe 16 at the bottom.

[0032] Optionally, the housing 1 can be fixed to the chassis of the fire truck.

[0033] like Figure 2 As shown, in one embodiment, the box 1 is further provided with a second partition 4. The second partition 4 extends along the width direction of the box 1. The two ends of the first partition 3 are respectively connected to the side wall of the box 1 in the width direction and the second partition 4. One end of the second partition 4 is connected to the side wall of the box 1 in the length direction, so that the first partition 3 and the second partition 4 cooperate to separate the water storage cavity 11 and the foam cavity 12. The water storage cavity 11 has an "L" shaped structure and its volume is a certain multiple of that of the foam cavity 12 to meet the mixing ratio of water and foam.

[0034] Optionally, the volume of the water storage chamber 11 can be in a 3:1 ratio with the volume of the foam chamber 12.

[0035] like Figure 3 and 4As shown, in a parallel implementation, the tank 1 is also provided with a second partition 4. The two ends of the second partition 4 are respectively connected to the two side walls in the length direction of the tank 1, and the two ends of the first partition 3 are respectively connected to the side wall in the width direction of the tank 1 and the second partition 4, thereby improving the structural strength inside the water tank. Connecting the two ends of the second partition 4 to the two side walls in the length direction of the tank 1 is equivalent to dividing the water storage cavity 11 into two chambers. The second partition 4 will block the water in the water storage cavity 11, reduce a certain water storage area in the water storage cavity 11, and reduce the water sloshing in the water storage cavity 11. At the same time, the second partition 4 is also provided with a first through hole 41, which extends upward from the bottom wall of the tank 1, also to ensure that the various areas in the water storage cavity 11 are connected.

[0036] like Figure 3 As shown, in one embodiment, the housing 1 is also provided with a third partition 5, which is spaced apart from the second partition 4. The two ends of the third partition 5 are respectively connected to the two side walls along the length of the housing 1. The third partition 5 is equivalent to dividing the water storage cavity 11 into another chamber. The third partition 5 will block the water in the water storage cavity 11. The third partition 5 and the second partition 4 reduce a certain water storage area of ​​the water storage cavity 11 and reduce the water sloshing in the water storage cavity 11. The third partition 5 is also provided with a second through hole 51, which extends upward from the bottom wall of the housing 1. This is also to ensure that the various areas in the water storage cavity 11 are connected, so as to facilitate the passage of water.

[0037] like Figures 1 to 3 As shown, in one embodiment, the housing 1 is also provided with a water inlet pipe 6 for the water storage chamber. The water inlet pipe 6 is connected to the water storage chamber 11. The water inlet pipe 6 includes a first arc segment 61 at the end that injects water into the water storage chamber 11, so that water enters from the top of the water storage chamber 11, increasing the water inlet pressure and preventing backflow of water during injection. The first arc segment 61 extends beyond the second partition 4, so that water can be injected into the water storage chamber 11. Of course, the first arc segment 61 can also extend beyond the third partition 5.

[0038] Optionally, the housing 1 can be equipped with one water inlet pipe 6, which enters the housing 1 from the bottom wall of the water storage chamber 11 or from the bottom of the foam chamber 12. Alternatively, two water inlet pipes 6 can be provided, one of which enters from the bottom wall of the water storage chamber 11 and the other from the bottom of the foam chamber 12. Of course, both of them can also enter from the bottom of the water storage chamber 11.

[0039] like Figure 1 and 2As shown, in one embodiment, the side of the housing 1 is also provided with a water pump suction port 7 and a water pump injection port 8 for communication with the water pump, so that the water pump can draw water through the water pump suction port 7. Of course, excess unused water can also be injected back into the water storage chamber 11 through the water pump injection port 8. The water pump injection port 8 is connected to the water pump injection pipe, which includes a second arc segment 81 at the end that injects water into the water storage chamber 11, so that water enters from the top of the water storage chamber 11, increasing the water inlet pressure when the water pump injects water and preventing backflow of water during injection.

[0040] like Figure 1 , 3 As shown in Figure 4, in one embodiment, a foam injection pipe 9 for injecting foam into the foam chamber 12 is also provided on one side of the water tank. The foam injection pipe 9 includes a third arc segment 91 at one end for injecting foam into the foam chamber 12, so that the foam is injected from above the foam chamber 12, increasing the injection pressure of the foam and preventing backflow of foam when it is injected. A foam suction port for connecting to the water pump is also provided on one side of the water tank. The foam suction port is connected to the foam chamber 12 through the foam suction pipe 10, so that the water pump can extract the foam in the foam chamber 12 to achieve the purpose of mixing with water and improve the fire extinguishing effect.

[0041] like Figure 3 As shown, in one embodiment, the water storage chamber 11 is provided with a first overflow pipe 13, and the foam chamber 12 is provided with a second overflow pipe 14. The first overflow pipe 13 and the second overflow pipe 14 are interconnected, so that the first overflow pipe 13 and the second overflow pipe 14 share the same overflow outlet, thereby reducing the number of overflow outlets and reducing production costs.

[0042] like Figure 1 As shown, in one embodiment, the water tank structure also includes two inspection covers 15, which are respectively embedded in the positions of two inspection ports, thereby reducing the protruding part of the inspection covers 15 on the tank body 1, so that most of the inspection covers 15 are embedded in the inspection ports, thereby making the upper surface of the inspection covers 15 roughly flush with the upper surface of the tank body 1, and also improving the space utilization above the inspection covers 15.

[0043] like Figure 5 As shown, in the second aspect, this application provides a fire truck, which includes the water tank structure of the fire truck provided in the first aspect, and also includes a fire-fighting drone 2. The drone 2 is located above the housing 1, so that the two inspection ports are located at the same end and are set near the rear end of the housing 1. The drone 2 will reduce the obstruction effect on maintenance personnel and facilitate maintenance personnel to carry out maintenance.
