Description

Technical Field

[0001] The present application relates to the technical field of fountains, and in particular to a water show performance device. Background Art

[0002] Projection systems are now being used more and more widely, with the advantages of a large visual range and realistic visual effects, especially water curtain projection, which is deeply loved by the public. In today's modern society with high requirements for cultural entertainment, people need a variety of cultural and entertainment experiences, and water curtain projection can meet people's needs. People can get a variety of experience effects through water curtain projection.

[0003] The Chinese patent with the authorization announcement number CN201215716Y discloses a fountain water curtain projection image device, which is composed of a nozzle, a delivery pipe, a water pump, and a projector. The water inlet of the water pump is installed in the fountain pool, and its outlet is connected to the delivery pipe; the nozzles are evenly installed on the delivery pipe, and the nozzle switches are installed at the lower ends of the nozzles.

[0004] With respect to the above technical solution, the inventors believe that the following defects exist: the water curtain formed by spraying upwards through multiple nozzles is relatively thin and easily affected by external factors such as wind, resulting in an uneven water curtain and poor projection effect. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a water show performance device, which has the advantages of a flat water curtain projection surface and good projection effect.

[0006] The above invention objectives of the present application are achieved through the following technical solutions:

[0007] A water show device comprises a water supply pipeline, a water curtain pipe and an impact plate; the impact plate is a strip groove with a long strip water outlet; the water outlet end of the water curtain pipe penetrates the side wall of the impact plate and is connected to the inside of the strip groove; the water inlet end of the water curtain pipe is connected to the water supply pipeline.

[0008] By adopting the above technical solution, the water curtain of the present application is sprayed out through the long strip water outlet of the impact plate, and the water curtain formed has a continuous and flat surface, which can clearly display the light and shadow in the water show.

[0009] Moreover, the water outlet end of the water curtain tube is located in the strip groove of the impact plate. The water flows into the strip groove and then sprays out from the water outlet. It will not form water mist, water vapor, etc. formed by the jet impact plate, etc., thus avoiding water waste and avoiding the presence of mist on the surface of the water curtain that affects the projection effect.

[0010] In a preferred example, the present application can be further configured as follows: a plurality of water outlet branches are connected between the water curtain pipe and the strip groove; and the diameter of the water outlet branch pipe is smaller than the diameter of the water curtain pipe.

[0011] By adopting the above technical solution, the outlet branch pipe with a smaller diameter than the water curtain pipe can make the water flow pressure entering the strip groove larger, thereby making the effective projection distance of the water curtain sprayed from the water outlet larger.

[0012] In a preferred example, the present application can be further configured as follows: it also includes a water curtain tube and a water curtain nozzle; the water inlet end of the water curtain tube is connected to the water supply pipeline; there are multiple water curtain nozzles, and the multiple water curtain nozzles are arranged in a straight line with equal intervals and connected to the water curtain tube to form a water outlet of the water curtain tube; the water outlet nozzle is in the same direction as the water outlet of the strip groove.

[0013] By adopting the above technical solution, a water curtain pipe and a water curtain nozzle are added to supplement the water volume of the water curtain sprayed from the water outlet of the impact plate. The water curtain can also be used alone as a water curtain to perform digital water curtains or as a water curtain with low projection requirements.

[0014] If the present application is suspended, the water outlet of the impact plate and the water outlet of the water curtain pipe are both facing downwards. When the water curtain sprayed by the impact plate falls to a certain distance and is affected by factors such as wind, resulting in an uneven surface of the water curtain, the water curtain sprayed by the water curtain nozzle can allow the water flow of the water curtain to fall smoothly.

[0015] If the application is installed on the ground, the water outlet of the impact plate and the water outlet of the water curtain pipe are both facing upwards. When the water curtain sprayed by the impact plate falls back after reaching a certain height or is affected by factors such as wind, it is easy to cause water mist and other problems that affect the projection effect. The water curtain sprayed by the water curtain nozzle can reduce the formation of water mist at high altitudes to a certain extent, ensuring that the water curtain has an effective projection area that meets the projection requirements.

[0016] In a preferred example, the present application can be further configured as follows: the length of the water outlet of the water curtain pipe is not less than the length of the water outlet of the impact plate.

[0017] By adopting the above technical solution, the length of the water outlet nozzle is not less than the length of the water outlet, which can ensure that the sprayed water curtain is sufficient to cover the width range of the water curtain.

[0018] In a preferred example, the present application can be further configured as follows: the water curtain nozzle is a jet nozzle.

[0019] By adopting the above technical solution, the jet nozzle can spray water columns with a long distance, and the water curtains sprayed by multiple water curtain nozzles at the same time have a long distance, which can form a larger effective projection area.

[0020] In a preferred example, the present application can be further configured as follows: the water curtain nozzle is close to one side of the impact plate.

[0021] By adopting the above technical solution, the water curtain nozzle and the impact plate are close to each other, and the corresponding nozzles and water outlets are also adjacent to each other, so that the water curtain and water curtain sprayed at the same time are merged to form a smoother water curtain.

[0022] In a preferred example, the present application can be further configured as follows: the water supply pipeline includes a water curtain water supply branch pipe and a water curtain water supply branch pipe; the water curtain pipe and the water curtain pipe are each one, and are parallel to the impact plate; the water curtain pipe is connected to multiple water curtain water supply branches at equal intervals; the water curtain pipe is connected to water curtain water supply branches that are less than the number of water curtain water supply branches.

[0023] By adopting the above technical solution, the water curtain tube is parallel to the impact plate, which can ensure that the water flow distance and water pressure of the water curtain tube entering the impact plate through the water outlet branch pipe are equal; the water curtain tube is parallel to the impact plate, and then the water outlet nozzle formed by the water curtain tube and the water curtain nozzle is parallel to the impact plate.

[0024] Multiple water curtain water supply branches are evenly spaced and supply water to the water curtain pipe at the same time, so that the water flow entering the impact plate from the water curtain pipe is evenly distributed, ensuring that the water outlet of the impact plate sprays a water curtain with uniform thickness and more stable. The water curtain pipe sprays the water curtain through the nozzle, and the water output is less than the water output of the impact plate. Therefore, the water curtain pipe is connected to the water curtain water supply branch pipes that are less than the number of water curtain water supply branches, so that the water curtain water supply branch pipes and the water curtain water supply branch pipes are fully used.

[0025] In a preferred example, the present application can be further configured as follows: each of the water curtain water supply branch pipe and the water curtain water supply branch pipe has a solenoid valve and a pressure regulating valve.

[0026] By adopting the above technical solution, the solenoid valve can be conveniently controlled to open and close the present application, so that the water outlet of the impact plate sprays out a water curtain, and the water outlet of the water curtain pipe sprays out a water curtain. The pressure regulating valve can be used to adjust the pressure of the sprayed water curtain or water curtain, thereby adjusting the spraying distance of the water curtain or water curtain, and then adjusting the effective projection area of ​​the water curtain or water curtain.

[0027] In a preferred example, the present application can be further configured as follows: the water supply pipeline includes a water storage pipe.

[0028] By adopting the above technical solution, a water storage pipe is provided on the water supply pipeline connected to the water curtain pipe, and the water storage pipe can ensure the water output from the water outlet and ensure sufficient water supply to form the water curtain.

[0029] In a preferred example, the present application can be further configured as follows: it also includes a mounting bracket; the water storage pipe is fixed to the mounting bracket; and the impact plate is connected to the mounting bracket via a plurality of fixing rods.

[0030] With the above technical solution, the mounting bracket is located on the outside of the impact plate, and the mounting bracket corresponds to the outside of the impact plate on a different side from the water outlet to avoid blocking the water outlet. The water storage pipe carries a large amount of water, and can be installed on the mounting bracket with a clamp or other fasteners and fixed to the equipment or area where the water show performance device is located. The impact plate connected to the mounting bracket by a fixing rod can be more stable, ensuring that the water curtain sprayed from the water outlet is stable.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. The water curtain of the present application is sprayed out through the long strip water outlet of the impact plate, and the water curtain plane formed is continuous and flat, which can clearly display the light and shadow in the water show;

[0033] 2. Add water curtain pipes and water curtain nozzles to supplement the water volume of the water curtain sprayed from the water outlet of the impact plate. It can also be used as a water curtain alone to perform digital water curtains or as a water curtain with low projection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The present application is further described in detail below in conjunction with the accompanying drawings.

[0042] Embodiment 1:

[0043] like Figure 1 As shown, the present application discloses a water show performance device, including a water curtain water supply branch pipe 1, a water curtain water supply branch pipe 2, a water storage pipe 3, a mounting bracket 4, a water curtain pipe 5, an impact plate 6, a water curtain pipe 7 and a water curtain nozzle 8. Each of the water curtain water supply branch pipe 1 and the water curtain water supply branch pipe 2 has a solenoid valve 9 and a pressure regulating valve 10.

[0044] like Figure 2 As shown, the water inlet end of the water curtain water supply branch pipe 1 is connected to the water storage pipe 3, and the water outlet end is connected to the water curtain pipe 5. The water storage pipe 3 is connected to the water curtain water supply branch pipe 1. The water storage pipe 3 can ensure the water volume demand of the water curtain pipe 5 and ensure sufficient water supply to form a water curtain.

[0045] The water show device of the present application is suspended and installed in the air, and the water curtain and water curtain are sprayed down from the air. The water storage pipe 3 is fixedly installed on the mounting bracket 4 by a clamp or other fixing parts, and a concave card slot 11 is provided under the mounting bracket 4. The mounting bracket 4 is mounted on the equipment or device such as the high-altitude bracket through the concave card slot 11.

[0046] like Figure 2 As shown, the impact plate 6 is a strip groove 13 with a long strip water outlet 12. A plurality of water outlet branches 14 are provided between the water curtain tube 5 and the impact plate 6, and the water outlet branches 14 are internally connected with the water curtain tube 5 and the strip groove 13 respectively. The water curtain is sprayed out through the long strip water outlet 12 of the impact plate 6, and the water curtain plane formed is continuous and flat, which can clearly display the light and shadow in the water show. Moreover, the water outlet end of the water curtain tube 5 is located in the strip groove 13 of the impact plate 6. The water flows into the strip groove 13 and then sprays out from the water outlet 12. It will not form water mist, water vapor, etc. formed by the spray impact plate 6, so as to avoid wasting water and also avoid the presence of mist on the surface of the formed water curtain to affect the projection effect.

[0047] like Figure 2 As shown, the impact plate 6 is connected to the mounting bracket 4 through a plurality of fixing rods 15. The impact plate 6 connected to the mounting bracket 4 through the fixing rods 15 can be more stable, ensuring that the water curtain sprayed from the water outlet 12 is stable. The impact plate 6 and the fixing rods 15 can be connected by the following structure: a plurality of connecting plates with connecting plate through holes are provided on the impact plate 6, and a fixing rod through hole corresponding to the connecting plate through hole is provided at the lower end of the fixing rod 15. Fasteners are used to pass through the connecting plate through holes and the fixing plate through holes in sequence to fix the fixing rod 15 to the connecting plate. A detachable installation method is adopted between the fixing rod 15 and the impact plate 6, so that personnel can disassemble and assemble the appropriate impact plate 6 according to the needs of the water show.

[0048] like Figure 2 As shown, the diameter of the water outlet branch pipe 14 is smaller than the diameter of the water curtain pipe 5. The water outlet branch pipe 14 with a smaller diameter than the water curtain pipe 5 can make the water flow pressure entering the strip groove 13 larger, thereby making the effective projection distance of the water curtain sprayed from the water outlet 12 larger.

[0049] like Figure 2As shown, the water inlet end of the water curtain water supply branch pipe 2 is connected to the water storage pipe 3 or other water supply pipelines, and the water outlet end is connected to the water curtain pipe 7, so that the water curtain pipe 7 can obtain sufficient water. There are multiple water curtain nozzles 8, and the multiple water curtain nozzles 8 are arranged in a straight line with equal spacing and connected to the water curtain pipe 7 to form a water outlet of the water curtain pipe 7; the water outlet nozzle and the water outlet 12 of the strip groove 13 are both arranged downward.

[0050] The electromagnetic valve 9 can be conveniently controlled to open and close the present application, so that the water outlet 12 of the impact plate 6 sprays out a water curtain, and the water outlet of the water curtain pipe 7 sprays out a water curtain. The pressure regulating valve 10 can be used to adjust the pressure of the sprayed water curtain or water curtain, thereby adjusting the spraying distance of the water curtain or water curtain, and then adjusting the effective projection area of ​​the water curtain or water curtain. By controlling the electromagnetic valve 9 and the pressure regulating valve 10 on the water curtain water supply branch pipe 1, the amount of water sprayed out of the water outlet 12 can also be increased to form a waterfall effect performance effect.

[0051] When falling from a high altitude (e.g. 60-70 meters) to a certain distance, the water flow is very easily affected by external factors such as wind, causing the surface of the water curtain sprayed from the water outlet 12 of the impact plate 6 to be uneven, and the image, light and shadow projected by the projector and other devices, as well as the image water show effect, cannot be clearly displayed. However, by simultaneously opening the water curtain water supply branch pipe 2 and allowing the water curtain nozzle 8 to spray the water curtain at the same time, the water flow sprayed from the water curtain at the water outlet 12 can be made to fall steadily.

[0052] Moreover, the water curtain tube 7 and the water curtain nozzle 8 of the present application supplement the water volume of the water curtain sprayed from the water outlet 12 of the impact plate 6, and can also be used alone as a water curtain to perform a digital water curtain or as a water curtain with low projection requirements.

[0053] like Figure 2 As shown, the length of the water outlet of the water curtain pipe 7 is not less than the length of the water outlet 12 of the impact plate 6. The length of the water outlet is not less than the length of the water outlet 12, which can ensure that the sprayed water curtain is sufficient to cover the width range of the water curtain.

[0054] like Figure 2 As shown, there is one water curtain tube 5 and one water curtain tube 7, both of which are parallel to the impact plate 6. The water curtain tube 5 is parallel to the impact plate 6, which can ensure that the water flow distance and water pressure of the water curtain tube 7 entering the impact plate 6 through the water outlet branch pipe 14 are equal; the water curtain tube 7 is parallel to the impact plate 6, and then the water outlet nozzle formed by the water curtain tube 7 and the water curtain nozzle 8 is parallel to the impact plate 6.

[0055] like Figure 2As shown, the water curtain pipe 5 is connected with multiple water curtain water supply branches 1 at equal intervals; the water curtain pipe 7 is connected with water curtain water supply branches 2 which are less than the number of water curtain water supply branches 1. Multiple water curtain water supply branches 1 are distributed at equal intervals and supply water to the water curtain pipe 5 at the same time, so that the water flow from the water curtain pipe 5 entering the impact plate 6 is evenly distributed, ensuring that the water outlet 12 of the impact plate 6 sprays a water curtain with uniform thickness and more stable. The water curtain pipe 7 sprays the water curtain through the nozzle, and the water output is less than the water output of the impact plate 6. Therefore, the water curtain pipe 7 is connected with water curtain water supply branches 2 which are less than the number of water curtain water supply branches 1, so that the water curtain water supply branches 2 and the water curtain water supply branches 1 are fully used.

[0056] like Figure 3 As shown, the water curtain nozzle 8 is a jet nozzle. The water curtain nozzle 8 is L-shaped, and the water outlet is lower than the water outlet 12. The jet nozzle can spray water columns with a long distance. The water curtains sprayed by multiple water curtain nozzles 8 at the same time have a long distance, which can form a larger effective projection area.

[0057] like Figure 3 As shown, the water curtain nozzle 8 is close to one side of the impact plate 6. The water curtain nozzle 8 is close to the impact plate 6, and the corresponding nozzles and water outlets 12 are also adjacent, so that the water curtains and water curtains sprayed at the same time are merged to form a smoother water curtain.

[0058] Embodiment 2:

[0059] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the present application is installed on the ground, and the water outlet 12 of the impact plate 6 and the water outlet nozzle of the water curtain pipe 7 are all facing upward. The water curtain water supply branch pipe 1, the water curtain water supply branch pipe 2, the water storage pipe 3, the mounting bracket 4, the water curtain pipe 5, the water curtain pipe 7, etc. are all located below the impact plate 6. The water outlet 12 and the water outlet nozzle can be oriented obliquely upward according to the actual performance needs to avoid the sprayed water curtain and water curtain falling back and hitting the water outlet 12 and the water outlet nozzle, affecting the effect of the formed water curtain and water curtain.

[0060] When the water curtain sprayed by the impact plate 6 falls back after reaching a certain height or is affected by factors such as wind, it is easy to cause water mist and other problems that affect the projection effect, the water curtain sprayed by the water curtain nozzle 8 can reduce the formation of water mist at high altitudes to a certain extent, ensuring that the water curtain has an effective projection area that meets the projection requirements.

[0061] Embodiment 3:

[0062] like Figure 5As shown, based on Example 1, a support rod 16 is connected between the impact plate 6 and each water curtain nozzle 8 of the present application to maintain the stability of the impact plate 6 and the water curtain nozzle 8. The two side walls of the impact plate 6 parallel to the water curtain tube 5 and the water curtain tube 7 are set as a movable plate 17 and a fixed plate 18. The water outlet branch pipe 14 is a hose, and the water outlet end of the water outlet branch pipe 14 passes through the movable plate 17. The support rod 16 is fixed between the fixed plate 18 and the water curtain nozzle 8.

[0063] like Figure 6 As shown, the top of the impact plate 6 includes an upper plate 19 connected to the movable plate 17 and a lower plate 20 connected to the fixed plate 18, and the upper plate 19 is connected to the fixed rod 15. The upper plate 19 and the lower plate 20 partially overlap, and the upper plate 19 and the lower plate 20 are slidably connected. The upper plate 19 is fixedly connected to the movable plate 17, and the movable plate 17 extends toward the fixed plate 18 with a side baffle 21, and the width of the side baffle 21 is not less than the maximum moving distance of the upper plate 19 and the lower plate 20, which is used to ensure that the water curtain is sprayed from the water outlet 12 located below the impact plate 6 to reduce water flow waste. The lower plate 20 is fixedly connected to the fixed plate 18.

[0064] like Figure 5 , Figure 6 As shown, a moving drive 22 is provided between the fixing rod 15 and the mounting bracket 4 , and the moving drive 22 is used to drive the fixing rod 15 to move laterally to control the overlapping area of ​​the upper plate 19 and the lower plate 20 , that is, to control and adjust the width of the water outlet 12 .

[0065] When the width of the water outlet 12 is large, the water flow is large, and the thickness of the formed water curtain is large, which can be used as a waterfall water show alone, and can also reduce the situation where the water curtain is uneven due to factors such as wind and is not enough to be used as a projection screen. When the width of the water outlet 12 is small, the water flow is small, but the water flow pressure is relatively increased, and the thickness of the formed water curtain is small. However, if the height difference of the water curtain is small, it can meet the water show projection needs without the assistance of the water curtain system formed by the water curtain nozzle 8 and the water curtain tube 7.

[0066] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
