Description

Technical Field

[0001] The utility model discloses a thunder cannon device, belonging to the technical field of water effect performance equipment, and specifically relates to a novel thunder cannon device for performance. Background Technique

[0002] For example, Chinese Patent No. 201920837573.8 provides a pneumatic explosion fountain, which includes: an air storage tank, the air storage tank is communicated with a compressed air source, an air flow control device is arranged above the air storage tank, and the air flow control device is arranged from bottom to top as follows: a straight pipe, a first flange, a first iron plate, a rubber gasket, a second iron plate, a second flange; a plug cover is also arranged on the second flange, and diversion steel plates are welded in the round holes of the first flange and the second flange. The diversion steel plates are in a circular ring shape, and a plurality of uniformly distributed diversion holes are arranged on them; an air discharge pipe; a water spray tube, the water spray tube is in a cylindrical shape with an open upper part, an air inlet hole is arranged at its bottom, the air inlet hole is connected to the tail end of the air discharge pipe, and an opening is arranged on its side wall.

[0003] The above patent relies on the air pressure difference between two chambers and the external atmospheric pressure to form an internal and external pressure balance. When the solenoid valve is closed, the pressure in the upper chamber is balanced with that in the lower chamber, and there is a strong pressure difference with the external atmospheric pressure. At this time, the diaphragm in the upper chamber forms a closed relationship with the air discharge pipe by relying on the pressure. The compressed air in the air storage tank cannot be exported through the air guide pipe, and the device is in a closed state.

[0004] When the solenoid valve is opened, due to the different gas flow rates under pressure, high, medium, and low three air pressure states are formed in the lower chamber, the upper chamber, and the outside. The pressure difference between the upper and lower chambers is larger than the pressure difference between the upper chamber and the outside. The diaphragm in the upper chamber is separated from the air guide pipe, and the compressed gas in the air storage tank is exported through the air guide pipe, and the device is in an open state.

[0005] At this time, there is a problem that once the pressure difference is not in a high pressure difference situation, or the gas flow rate is slow, the compressed gas pressure is low, and the pressure difference is not enough to push the diaphragm in the chamber, the device cannot work properly.

[0006] For example, Chinese Patent No. 200820161427.X discloses a salute cannon fountain, which includes an air storage tank, a solenoid valve, and a spray pipe. The air storage tank is communicated with a compressed air source, the outlet of the spray pipe is arranged upward, a cover body is arranged on the air storage tank, the inner cavity of the cover body is connected with the inner cavity of the air storage tank, an air bag is fixed in the cover body, a sealing cover plate is connected to the lower side of the air bag, a U-shaped air outlet pipe is also arranged in the air storage tank, one end of the air outlet pipe extends into the cover body and is covered by the sealing cover plate, the other end of the air outlet pipe is connected to the inlet of the solenoid valve through a pipeline and is connected to the air bag, the outlet of the solenoid valve is connected to the atmosphere, and the inlet of the solenoid valve is also connected to compressed air.

[0007] The above patent increases the instantaneous gas release volume by magnifying the solenoid valve. The electromagnetic equipment bears huge pressure, which will increase the failure rate of the equipment.

[0008] In summary, the water effect devices in the prior art for performances have the problems of relatively low effect height and unsatisfactory sound effects. The installation conditions are limited to pools and lakes. Summary of the Invention

[0009] Purpose of the utility model: To provide a novel thunder cannon device for performances to solve the above-mentioned problems.

[0010] Technical solution: A novel thunder cannon device for performances, the thunder cannon device is composed of a bracket, a water storage tank, a gas storage tank, a solenoid valve and a pilot air release device;

[0011] The water storage tank and the gas storage tank are installed on the bracket and connected by a gas pipe; the pilot air release device is installed on the gas storage tank and connected to the gas storage tank, and the solenoid valve is installed on the pilot air release device to control the pilot air release device.

[0012] The pilot air release device is composed of a cavity, a diaphragm, a spring and a gland. The gland contains a small hole leading to the gas storage tank, so that the pressure in the cavity is kept balanced with the pressure in the gas storage tank.

[0013] In a further embodiment, when the solenoid valve is in the open state, the air release speed of the solenoid valve and the gas flow rate in the small hole of the pilot air release device have a larger difference, the pressure difference between the gas in the cavity and the outside pressure decreases, and the compressed air in the gas storage tank quickly pushes open the diaphragm and enters the gas pipe, and the device is in the working state.

[0014] In a further embodiment, when the solenoid valve is in the closed state, the compressed air in the gas storage tank enters the cavity through the connecting small hole, and the pressure quickly reaches balance. At this time, the diaphragm in the cavity is quickly pressed tightly by the spring potential energy, and the device is in the closed state.

[0015] In a further embodiment, the gas storage tank is provided with a drain hole and an air inlet hole communicating with the inside.

[0016] In a further embodiment, the top of the gas storage tank is provided with a water converging reducer and a nozzle. The large-diameter head of the water converging reducer is fixedly connected to the top of the gas storage tank, and the small-diameter head is fixedly connected to the nozzle.

[0017] In a further embodiment, one end of the gas pipe is connected to the water storage tank and the other end is connected to the gas storage tank.

[0018] The utility model has the following beneficial effects:

[0019] 1. Compared with the pneumatic explosion fountain that uses the pressure difference between two chambers and the outside world to control the start and stop of the device, the utility model reduces one chamber and uses a control method that combines the pressure difference and elastic potential energy. First, the structure is more concise, the space is compressed, and the appearance is more beautiful. Second, the use of various mechanical parts is effectively reduced, greatly reducing the failure rate. And it well compresses the production cost, reduces the weight of the device, and makes the installation more convenient.

[0020] 2. The utility model controls the start and stop of the device through an internal pilot release device and a solenoid valve. The solenoid valve only plays a control role, and the huge instantaneous gas release volume at one time will be shared by the pilot release device. Greatly reduce the equipment failure caused by the enlargement of the solenoid valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A new type of thunder cannon device used for performances, such as Figures 1 to 3 As shown, the thunder cannon device is composed of a bracket 10, a water storage tank 7, an air storage tank 5, a solenoid valve 1 and a pilot air release device 2;

[0029] In one embodiment, Figures 1 to 3 As shown, the water tank 7 and the air tank 5 are installed on the bracket 10 and are connected by the air duct 6; the pilot air release device 2 is installed on the air tank 5 and is connected to the air tank 5, and the solenoid valve 1 is installed on the pilot air release device 2 to control the pilot air release device 2.

[0030] In one embodiment, Figures 1 to 3 As shown, the pilot air release device 2 is composed of a cavity 21, a diaphragm 22, a spring 23 and a pressure cover 24. The pressure cover contains a small hole 28 leading to the gas storage tank 5, so that the pressure in the cavity and the gas storage tank 5 are balanced.

[0031] Specifically, the cavity 21 is composed of an upper and lower block, the diaphragm 22 is located between the upper and lower blocks, a sealing ring 26 is provided between the upper and lower blocks of the cavity 21, a guide hole 25 is provided in the upper half of the cavity 21, and a gas release pipe 27 is provided in the lower half of the cavity 21, the gas release pipe 27 is connected to the cavity 21, and is located in the gas storage tank 5;

[0032] When the solenoid valve 1 is in a closed state, the pressure of the cavity 21 and the gas tank 5 is balanced due to the presence of the guide hole 25, and the device is in a closed state. When the solenoid valve 1 is opened, the gas in the cavity 21 is lost, and the compressed air in the gas tank 5 does not have time to enter the cavity 21 through the guide hole 25. The compressed gas pushes the diaphragm 22 open, and the device is in an open state, releasing a large amount of compressed air into the air release pipe 27 at one time.

[0033] In one embodiment, Figures 1 to 3As shown, when the solenoid valve 1 is in the open state, the gas release speed of the solenoid valve 1 and the gas flow rate in the small hole of the pilot gas release device 2 become different, the pressure difference between the gas in the cavity and the outside decreases, and the compressed air in the gas storage tank 5 quickly pushes open the diaphragm and enters the air guide pipe 6, and the device is in the working state.

[0034] In one embodiment, as Figures 1 to 3 shown, when the solenoid valve 1 is in the closed state, the compressed air in the gas storage tank 5 enters the cavity through the connecting small hole, and the pressure quickly reaches equilibrium. At this time, the diaphragm in the cavity is quickly pressed tightly by the spring potential energy, and the device is in the closed state.

[0035] In one embodiment, as Figures 1 to 3 shown, the gas storage tank 5 is provided with a drain hole 3 and an air inlet hole 4 communicating with the inside.

[0036] In one embodiment, as Figures 1 to 3 shown, a water converging reducer 8 and a nozzle 9 are provided at the top of the gas storage tank 5. The large-diameter head of the water converging reducer 8 is fixedly connected to the top of the gas storage tank 5, and the small-diameter head is fixedly connected to the nozzle 9.

[0037] In one embodiment, as Figures 1 to 3 shown, one end of the air guide pipe 6 communicates with the water storage tank 7 and the other end communicates with the gas storage tank 5.

[0038] Working principle: The present invention provides a novel performance water effect device. The components of the thunder cannon device include an air inlet hole 4, a gas storage tank 5, a pilot gas release device 2, a nozzle 9, etc. At the top of the gas storage tank 5, there is an in-built pilot gas release device 2. The solenoid valve 1 is located at the top of the gas storage tank 5 and is used for balancing the internal and external pressures. The nozzle 9 uses a water converging reducer 8 to make the water flow more concentrated when released and the sound effect clearer;

[0039] The present invention decomposes a large solenoid valve into a solenoid valve 1 and a pilot gas release device 2. The device will only have one chamber to form a pressure difference with the outside. The cavity of the pilot gas release device 2 contains a diaphragm and a spring. The gland of the gas release device contains a small hole leading to the gas storage tank 5 to keep the pressure in the cavity and the gas storage tank 5 balanced.

[0040] When the solenoid valve 1 is opened, due to the huge difference between the gas release speed of the solenoid valve 1 and the gas flow rate in the small hole of the pilot gas release device 2, the pressure difference between the gas in the cavity and the outside quickly decreases, and the compressed air in the gas storage tank 5 quickly pushes open the diaphragm and enters the gas release pipeline, and the device works.

[0041] When the solenoid valve 1 is closed, the compressed air in the air storage tank 5 enters the cavity through the connecting small hole, and the pressure quickly reaches equilibrium. At this time, the diaphragm in the cavity is quickly pressed tightly by the spring potential energy, and the device is closed.

[0042] Compared with the pneumatic explosion fountain that uses the pressure difference between two chambers and the outside world to control the start and stop of the device, the utility model reduces one chamber and uses a control method that combines the pressure difference and elastic potential energy. First, the structure is more concise, the space is compressed, and the appearance is more beautiful. Second, the use of various mechanical parts is effectively reduced, greatly reducing the failure rate. And the manufacturing cost is well compressed, the weight of the device is reduced, and the installation is more convenient.

[0043] In addition, the utility model controls the start and stop of the device through a built-in pilot release device and the solenoid valve 1 together. The solenoid valve 1 only plays a control role, and the huge instantaneous gas release volume at one time will be shared by the pilot release device. The equipment failure caused by the enlargement of the solenoid valve 1 is greatly reduced.

[0044] When installed in a water-free area, an auxiliary water inlet system can be added for performances when the device is far away from lakes and pools.

[0045] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the utility model.
