[0029] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] Reference Figures 1 to 5As shown, a preferred embodiment of the present application of a water cannon salute machine includes a mounting base 1, an air tank assembly 2, a water cannon pipe 3 and a salute pipe 4. The air tank assembly 2 includes an air tank 21, which is connected to the mounting base 1. The air tank 21 has an output pipe 211. The water cannon pipe 3 and the salute pipe 4 are both used to be detachably connected to the output pipe 211.

[0031] In practical applications, when water effects are needed, the water cannon pipe 3 is connected to the output pipe 211, and the water cannon pipe 3 and the air tank assembly 2 work together to achieve water effects. When ceremonial cannon effects are needed, the ceremonial cannon pipe 4 is connected to the output pipe 211, and the ceremonial cannon pipe 4 works with the air tank assembly 2 to achieve ceremonial cannon effects. That is, the water cannon ceremonial cannon machine of this utility model can achieve both ceremonial cannon effects and water effects, and has low operating costs.

[0032] Specifically, water cannon pipe 3 and ceremonial cannon pipe 4 can be used at different times. When gas tank assembly 2 is connected to water cannon pipe 3, the water cannon ceremonial cannon machine can achieve water effects. When gas tank assembly 2 is connected to ceremonial cannon pipe 4, the water cannon ceremonial cannon machine can achieve ceremonial cannon effects. After achieving water effects through water cannon pipe 3, if ceremonial cannon effects are to be achieved, ceremonial cannon pipe 4 is required to replace water cannon pipe 3.

[0033] In this embodiment, the end of the output pipe 211 away from the gas tank 21 along its length has a first thread, the end of the water cannon pipe 3 along its length has a second thread, and the end of the salute pipe 4 along its length has a third thread. The second thread and the third thread are both used to engage with the first thread. That is, the water cannon pipe 3 and the salute pipe 4 are detachably connected to the output pipe 211 by means of threaded connection. The structure is simple and the installation and disassembly operations are convenient.

[0034] In this embodiment, the gas tank assembly 2 further includes a strap 22, a first locking member 23, and a second locking member 24. The two ends of the strap 22 along its length are fixedly connected to the mounting base 1 by the first locking member 23 and the second locking member 24, respectively. The strap 22 is wrapped around the gas tank 21 and the strap 22 is pressed against the gas tank 21. That is, the gas tank 21 is fixedly connected to the mounting base 1 by the strap 22. The structure is simple and easy to install. Compared with customized fixed brackets or complex clamps, it can reduce the production and maintenance costs of the water cannon salute machine. The strap 22 is made of metal.

[0035] Furthermore, the first locking element 23 is a screw, and the second locking element 24 is a handle bolt. Specifically, based on the handle bolt, the strap 22 can be fixed by manual operation, which is convenient and easy to disassemble and assemble. The handle bolt is L-shaped.

[0036] In this embodiment, the gas tank assembly 2 further includes a first high-pressure connector 25 and a solenoid valve 26. The first high-pressure connector 25 is connected to the gas tank 21, and the solenoid valve 26 is connected to the output pipe 211. Specifically, the first high-pressure connector 25 is used to connect an air pipe, which is connected to an air compressor. Compressed air is delivered to the gas tank 21 through the air pipe and the first high-pressure connector 25 by the air compressor. In practical applications, the opening and closing of the output pipe 211 is controlled by controlling the energization of the solenoid valve 26. When the solenoid valve 26 is energized, the output pipe 211 is open, and the high-pressure gas in the gas tank 21 is output through the output pipe 211. When the solenoid valve 26 is de-energized, the output pipe 211 is closed. In the off state; for example, when the water cannon salute machine achieves water effects, the water cannon pipe 3 is connected to the output pipe 211. Water is injected into the water cannon pipe 3 while the solenoid valve 26 is energized. As a result, high-pressure gas is output from the gas tank 21 through the output pipe 211 to the water cannon pipe 3 and drives the water to be output from the water cannon pipe 3, thus forming water effects; similarly, when the water cannon salute machine achieves salute effects, the salute pipe 4 is connected to the output pipe 211. The salute material is loaded into the salute pipe 4. Then, the solenoid valve 26 is energized so that high-pressure gas is output from the gas tank 21 through the output pipe 211 to the salute pipe 4 and drives the salute material to be output from the salute pipe 4, thus achieving salute effects.

[0037] Furthermore, the gas tank assembly 2 also includes a pressure relief valve 27, which is connected to the gas tank 21 and is spaced apart from the first high-pressure connector 25. The output pipe 211 is located between the pressure relief valve 27 and the first high-pressure connector 25. Specifically, when the pressure inside the gas tank 21 exceeds the set pressure of the pressure relief valve 27, the pressure relief valve 27 automatically opens to release pressure, preventing the pressure inside the gas tank 21 from becoming too high, thus ensuring high safety performance. The set pressure of the pressure relief valve 27 is set according to the actual application, and this application does not impose any restrictions on it. In addition, the output pipe 211 is located between the pressure relief valve 27 and the first high-pressure connector 25, which is a reasonable layout and facilitates processing.

[0038] In this embodiment, the mounting base 1 includes a mounting plate 11 and a support foot 12. The support foot 12 is connected to the bottom surface of the mounting plate 11. The mounting plate 11 has a vertically penetrating first clearance hole 1101. The gas tank 21 is connected to the top surface of the mounting plate 11. The bottom of the gas tank 21 is provided with a discharge pipe 212, which passes through the first clearance hole 1101. The gas tank assembly 2 also includes a first valve 28, which is connected to the discharge pipe 212. In practical applications, as mentioned above, the realization of water effects requires water to be input into the water cannon pipe 3. Therefore, it is difficult to avoid water entering the gas tank 21 through the output pipe 211. In this application, the discharge pipe 212 can discharge the water in the gas tank 21. Specifically, by opening the first valve 28, the water in the gas tank 21 is discharged from the discharge pipe 212. In addition, when the water cannon salute machine is idle, the gas in the gas tank 21 can also be discharged from the discharge pipe 212 by opening the first valve 28 to ensure safety.

[0039] The first clearance hole 1101 allows the gas tank 21 to be fixed by the strap 22 and the discharge pipe 212 to not interfere with the mounting plate 11. The structure is simple and the water cannon salute machine has a compact structure.

[0040] It should be noted that the first valve 28 is a ball valve, and the first valve 28 is normally closed. When the gas tank 21 needs to drain or vent, the first valve 28 will open.

[0041] In this embodiment, the water cannon salute machine also includes an aviation case 5, and the gas tank assembly 2 is disposed inside the aviation case 5. The aviation case 5 includes a case body 51 and a case cover 52. The case cover 52 is detachably connected to the case body 51, and the support leg 12 is connected to the bottom surface of the cavity of the case body 51. The bottom surface of the cavity of the case body 51 has a second clearance hole 5101 that runs vertically through it. The second clearance hole 5101 is directly opposite to the first clearance hole 1101. The setting of the second clearance hole 5101 makes it convenient for the operator to open or close the first valve 28, so that the gas tank 21 can drain or vent smoothly.

[0042] It should be noted that in practical applications, when water effects or cannon effects are required, the box cover 52 needs to be opened, and then the water cannon pipe 3 or cannon pipe 4 is installed on the output pipe 211. When the water cannon cannon machine is working, the box body 51 can be kept fixed by auxiliary tools, such as by multiple limiting blocks surrounding the box body 51 and the limiting blocks contacting the box body 51, thereby keeping the box body 51 fixed and ensuring the smooth operation of the water cannon cannon machine. The flight box 5 is designed to facilitate the movement and handling of the water cannon cannon machine. The flight box 5 is existing technology. The bottom of the box body 51 is connected to casters, which will not be described in detail in this application.

[0043] Furthermore, the mounting base 1 also includes a handle 13, which is connected to the top surface of the mounting plate 11. The handle 13 is designed to facilitate the operator to install the mounting base 1 and the gas cylinder assembly 2 into the housing 51 or to remove the mounting base 1 and the gas cylinder assembly 2 from the housing 51, making operation convenient.

[0044] In this embodiment, the water cannon pipe 3 includes a pipe body 31, a connecting seat 32, and a second high-pressure connector 33. The pipe body 31 includes a first pipe section 311, a transition section 312, and a second pipe section 313. The inner diameter of the first pipe section 311 is larger than the inner diameter of the second pipe section 313. The transition section 312 transitionally connects the first pipe section 311 and the second pipe section 313. The connecting seat 32 is connected to one end of the first pipe section 311 along its length away from the second pipe section 313. The connecting seat 32 is used for detachable connection with the output pipe 211, that is, the connecting seat 32 has the aforementioned second thread. The second high-pressure connector 33 is connected to the first pipe section 311. Specifically, when the water cannon salute machine uses the water cannon pipe 3 to achieve water effects, the second high-pressure connector 33 is connected to a water supply source through a pipe. Water is input into the water cannon pipe 3 through the pipe and the high-pressure connector, and the water is output through the first pipe section 311, the transition section 312, and the second pipe section 313 under the action of high-pressure gas to form water effects.

[0045] The second pipe section 313 has a smaller inner diameter than the first pipe section 311, which increases the injection pressure, thus creating a high-pressure jet when water is output from the second pipe section 313. The transition section 312 is conical, with its inner diameter gradually decreasing from the first pipe section 311 to the second pipe section 313. The maximum inner diameter of the transition section 312 is equal to the inner diameter of the first pipe section 311, and the minimum inner diameter of the transition section 312 is equal to the inner diameter of the second pipe section 313.

[0046] In this embodiment, the connecting seat 32 has a communicating hole, the inner diameter of which is smaller than the inner diameter of the first pipe segment 311. At this time, the first pipe segment 311 is connected to the connecting seat 32 through a tapered transition portion. The inner diameter of the tapered transition portion gradually decreases from the second pipe segment 313 to the connecting seat 32 to achieve a transitional connection between the first pipe segment 311 and the connecting seat 32. This application does not impose any restrictions on this.

[0047] In this application, the water cannon salute machine also includes a control box connected to the mounting plate 11. The control box contains a control circuit board and a water supply pipe. The water supply pipe is equipped with an integrated electromagnetic flow control valve. One end of the water supply pipe is connected to a water source, and the other end is connected to a second high-pressure connector 33 via a pipe. Both the integrated electromagnetic flow control valve and the solenoid valve 26 are electrically connected to the control circuit board. The control box has a first switch and a second switch, both electrically connected to the control circuit board. The first switch outputs a switching signal to cause the control circuit board to control the opening and closing of the solenoid valve 26. The second switch outputs a switching signal to cause the control circuit board to control the opening and closing of the solenoid valve 26. The circuit board controls the opening and closing of the electromagnetic flow control integrated valve and its opening degree, which is existing technology and will not be described in detail here. In addition, the electromagnetic flow control integrated valve has a built-in flow meter. Therefore, when water is supplied to the water cannon pipe 3 through the water supply pipe or pipeline, the electromagnetic flow control integrated valve can monitor the amount of water entering the water cannon pipe 3. Furthermore, the control box is also equipped with a display screen, which is electrically connected to the control circuit board. The display screen can display the monitoring results of the flow meter, so that the staff can understand the amount of water entering the water cannon pipe 3. This eliminates the need for manual detection of the amount of water in the water cannon pipe 3 or detection of whether the water cannon pipe 3 is full, making the operation convenient.
