Description

Technical Field

[0001] This utility model relates to a water curtain manufacturing device, specifically to a swinging water curtain that can be used for projection. Background Technology

[0002] Water screen projection involves spraying water into a thin, transparent "screen" and then projecting images or videos onto it. Especially at night or in low-light conditions, the reflection and refraction of images on the water screen create a spectacular effect.

[0003] Referring to Chinese Patent Publication No. CN206039129U, a water screen projection device is disclosed, which solves the problem that when water vapor adheres to the lens of the projector, a water vapor layer will form, which will cause the projected image to be blurry. The key points of its technical solution are that it includes a water screen and a projector. The projector includes a lens and a housing, including a fan fixed to the housing and an air guide hole that directs the air from the fan to the lens. The air guide hole is opened in the housing and is arranged around the outer edge of the lens. The wall of the air guide hole is inclined towards the lens, so as to achieve the effect of making it difficult for a water vapor layer to form on the lens.

[0004] Among the existing technologies, including the aforementioned patents, water curtain projection is a relatively conventional technology, but currently there are few methods that use a spray gun to swing to create a water curtain. Utility Model Content

[0005] The purpose of this invention is to provide a swinging water screen that can be used for projection, in order to solve the above-mentioned problems.

[0015] The cabin includes a main water supply pipe, which is assembled with the rotatable flange and connected to the gooseneck-shaped connecting pipe.

[0016] Preferably, a regulating valve is fixedly installed on the main body.

[0017] Preferably, the end face of the disc is provided with guide rail grooves symmetrically arranged about the center of the waist groove.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown, a swinging water screen that can be used for projection includes a drive motor 1, a reducer 11 fixedly mounted on the end face of the drive motor 1, the input end of the reducer 11 being connected to the output end of the drive motor 1, and multiple water gun components 2 arranged equidistantly on both sides of the reducer 11 and circumferentially rotating. A disc 3 with an eccentrically arranged guide rod 31 mounted on the end face of the reducer 11 is fixedly mounted on the output end of the reducer 11.

[0031] It also includes a multi-section linkage 4, one end of which is rotatably mounted on the guide rod 31. The water gun component 2 includes a connecting rod 21, which is assembled on the multi-section linkage 4.

[0032] Specifically, in this embodiment, a main water supply pipe 55, which is fixedly connected to an external water supply system, is fixedly mounted on the mounting bracket 5. Multiple equidistant main pipe bodies 51 are connected in parallel to the main water supply pipe 55. A gooseneck-shaped connecting pipe body 52 is fixedly connected to the end of each main pipe body 51. A rotatable flange 53 is fitted onto the port of the gooseneck-shaped connecting pipe body 52, and the water gun 2 is fitted onto the rotatable flange 53, thus enabling the water gun 2 to rotate circumferentially. Water in the main water supply pipe 55 is supplied by a water pump 200 bolted to the mounting bracket 5.

[0033] Furthermore, in this embodiment, after the water gun 2 swings back and forth, the trajectory of the sprayed water is a spiral. The faster the water gun 2 swings per unit time, the greater the spiral degree, and the better the projection effect. Moreover, within the width of this trajectory, the water falls continuously and naturally under the influence of gravity, forming a water curtain. This increases the area of ​​reflection and refraction during projection, resulting in a better projection effect. Figure 5 As shown.

[0034] Furthermore, the multi-section linkage 4 described in the above embodiment includes a rod 41 and a short rod 42. Each pair of adjacent rods 41 are rotatably mounted at both ends of the short rod 42, and the connecting rod 21 is welded to the short rod 42. Figure 1 It can be known that...

[0035] It should be noted that the sealing of the joint is achieved by known technologies such as rubber rings in the above-mentioned connecting structure, so it will not be described in detail.

[0036] In the above technology, the disc 3 on the drive motor 1 drives the multi-section linkage group 4 to transmit and pull multiple water gun parts 2 distributed on both sides, thereby enabling the water gun parts 2 to deflect at a predetermined angle to create a water curtain.

[0037] As a further embodiment of this utility model, combined with Figure 4 As can be seen, the water gun component 2 in the embodiment is divided into a chamber 22 and a nozzle 24 according to its structure. The first end of the chamber 22 is inserted into the water inlet end of the nozzle 24, and the nozzle 24 is fixed by a fixed flange 23 connected to the first end by thread. The second end of the chamber 22 is welded to the connecting rod 21.

[0038] Furthermore, the hull 22 includes a main water supply pipe, which is assembled with a rotatable flange 53 and connected to a gooseneck-type connecting pipe 52.

[0039] Specifically, a regulating valve 54 is fixedly installed on the main pipe 51 in this embodiment, which can be used to control the water flow rate output to the nozzle 24.

[0040] Furthermore, in this embodiment, the nozzle 24, the chamber 22, and the gooseneck connecting pipe 52 are all designed to be detachable, which facilitates the replacement of components damaged by scale corrosion and increases the maintainability of the device.

[0041] Secondly, in the embodiment, the spray surface of the water gun 2 is a water column, and when the water gun 2 is not swinging, the water sprayed from the nozzle 24 of the water gun 2 is a water column, which forms a rectangular water curtain area after swinging.

[0042] As a further embodiment of this utility model, guide rail grooves 33 are respectively provided on the end face of the disc 3, which are symmetrically arranged about the center of the waist groove 32. An adjusting screw 34 with a nut extending to the outer side of the disc 3 is rotatably provided in the waist groove 32. The adjusting screw 34 is threadedly connected to the moving part 35 located on the end face of the disc 3 and assembled in the guide rail groove 33. The guide rod 31 is fixedly installed on the end face of the moving part 35.

[0043] Specifically, in this embodiment, rotating the nut drives the moving part 35 to move along the guide groove 33, thereby adjusting the distance between the guide rod 31 and the center of the disk 3. This allows for adjustment of the deflection angle of the water gun component 2. The farther the moving part 35 is from the center of the disk 3, the larger the deflection angle of the water gun component 2; conversely, the smaller the deflection angle. This allows for flexible adjustment of the water curtain's shape and effect in different application scenarios, meeting diverse needs.

[0044] As another embodiment of the present invention, a marker rod 6 is fixedly installed on the moving part 35, which extends out of one of the guide rail grooves 33 and onto the outside of the disc 3.

[0045] Specifically, the disc 3 has a through hole through which the indicator rod 6 can pass. So when the distance between the guide rod 31 and the center of the disc 3 is adjusted, the indicator rod 6 will also move synchronously. The angle of deflection of the water gun component 2 after adjustment can be known through the indicator rod 6.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
