Technical Field
[0001] This utility model relates to the technical field of self-lifting water film devices, and in particular to a self-lifting water film device. Background Technology
[0002] In city squares, parks, and various tourist attractions, fountains serve as important landscape features, enhancing the aesthetics of the environment and providing people with a pleasant visual experience. Most fountain nozzles are fixedly installed, rising above the ground or water surface when spraying water. However, this fixed installation has several drawbacks: in dry fountains in squares, nozzles rising above the ground disrupt the overall flatness of the square, affecting the cleanliness and beauty of the ground, inconveniencing pedestrians, and potentially causing tripping accidents; in fountains where the water surface requires a high level of aesthetic appeal, nozzles protruding from the water when not spraying water also disrupt the harmonious beauty of the water surface, affecting the overall landscape effect. Therefore, developing a nozzle device that automatically rises when spraying water and automatically lowers and retracts when not spraying water is of great significance for improving the aesthetics and practicality of fountain landscapes.

[0061] Effect: Ensures that water can enter the lower outer pipe 3 stably, pushes the lifting component 1 to rise, and forms a water film spray.
[0062] Working principle: When spraying water:
[0063] After water enters the lower outer pipe 3 from the inlet 4, the water flow pushes the lower block 11, causing the lifting component 1 to move upward as a whole.
[0064] The slider 13 slides along the inner wall of the upper outer tube 2 until it contacts and seals the annular limit at the top of the upper outer tube 2.
[0065] The water flows through the lower block 11, the gap between the upper outer pipe 2 and the water pipe 15, the water inlet 12, and the support 14 in sequence, and finally sprays out from the gap formed by the pressure cap 17 and the water pipe 15 to form a water film.
[0066] When the water spray stops: the water pump stops supplying water, and the water pressure in the lower outer pipe 3 disappears.
[0067] Under the influence of its own weight, the lifting component 1 moves downward, and the slider 13 slides down along the inner wall of the upper outer tube 2 until the lower part of the slider 13 contacts the top of the lower outer tube 3.
[0068] The nozzle is hidden inside the lower outer pipe 3, returning to its initial state, waiting for the next water spray.
[0069] Based on the above structure and working principle, the self-lifting water film device of this utility model realizes the automatic lifting function, improves the aesthetics and safety of the fountain, and has the advantages of simple structure, no need for external power and control, and strong adaptability.

[0071] In this embodiment, it is necessary to explain in detail the matching of the outer diameter with the inner diameter of the lower outer pipe 3: the outer diameter of the lower block 11 is matched with the inner diameter of the lower outer pipe 3 to ensure that the lower block 11 can fit tightly inside the lower outer pipe 3 and prevent water from leaking from the gap between the lower block 11 and the lower outer pipe 3.
[0072] Chamfer design: The lower circumference of the lower block 11 is chamfered, which matches the chamfer on the inner wall of the upper top of the lower outer tube 3. This chamfer design helps the lower block 11 to smoothly enter the lower outer tube 3 and slide smoothly during the rising and falling of the lifting component 1, reducing friction and wear.
[0073] Function: The lower block 11 is located at the bottom of the water pipe 15, sealing the bottom of the water pipe 15 and preventing water leakage from the bottom. At the same time, as part of the lifting component 1, the lower block 11, in cooperation with the lower outer pipe 3, ensures the stability and smoothness of the lifting component 1 during the rising and falling process.
[0074] In some specific embodiments, the water inlet holes 12 are evenly distributed on the wall of the water pipe 15. The size and number of holes are designed according to the actual required water flow rate.
[0075] It should be noted that the water inlet holes 12 are evenly distributed on the wall of the water pipe 15.

An annular rubber pad is provided on the upper part of the slider 13. When the slider 13 contacts the annular limit at the top of the upper outer tube 2, the annular rubber pad fits tightly with the annular limit to achieve a seal.
[0081] Function: The slider 13 is sleeved on the outside of the water pipe 15 and is fixedly connected to the water pipe 15. The slider 13 slides up and down on the inner wall of the upper outer pipe 2 to realize the raising and lowering of the lifting component 1. When the slider 13 rises to the top of the upper outer pipe 2 and contacts the annular limit, the annular rubber gasket seals, preventing water from leaking from the gap between the upper outer pipe 2 and the water pipe 15.
[0082] Effect: The design of slider 13 ensures the stability and sealing of lifting component 1 during the rising and falling process. The combined use of PTFE ring and annular rubber gasket reduces friction while ensuring a sealing effect, improving the overall performance and reliability of the device.

[0114] Example: Application of landscape fountains in hotels
[0115] A hotel has installed a landscape fountain in its courtyard to enhance its luxury and aesthetics, attracting more guests. Several self-lifting water film devices have been selected and installed at the bottom of the fountain, working in conjunction with the pool's lighting system to create a dreamlike visual effect.
[0116] Installation process
[0117] Location determination: Based on the design drawings of the fountain pool, multiple installation points are pre-set at the bottom of the pool and evenly distributed to ensure the uniformity and aesthetics of the fountain effect.
[0118] Installation: Securely connect the mounting base at the bottom of the lower outer pipe of the self-elevating water film device to the pre-embedded parts at the bottom of the fountain to ensure the stability of the device. Both the upper and lower outer pipes are made of stainless steel and are welded to ensure a tight seal, providing long-term resistance to corrosion from the pool water.
[0119] Water pipe connection: Connect the water inlet of the device to the centralized water supply system of the fountain pool through pipes to ensure that each device receives stable water pressure and flow. Install sealing gaskets at the connection points to prevent water leakage and ensure the normal operation of the fountain.
[0120] Electrical connection: Connect the fountain's lighting system to the hotel's intelligent control system to achieve automatic adjustment of light color and brightness, and synchronize the operation with the self-lifting water film device to create a variety of colorful fountain performances.
[0121] Working principle
[0122] When spraying water
[0123] Initial state: The self-lifting water film device is hidden at the bottom of the fountain pool, the nozzle is located inside the lower outer pipe, and the slider is at the top of the lower outer pipe, keeping it flush with the bottom of the pool, so as not to affect the calm and beautiful appearance of the pool water.
[0124] Starting the fountain: When the fountain is turned on, the water pump starts, and water flows into the lower outer pipe through the inlet. The water flow pushes the lower block, causing the lifting components to rise. The slider slides along the inner wall of the upper outer pipe, and the PTFE ring reduces friction, ensuring a smooth rise. The water flows sequentially through the lower block, the gap between the upper outer pipe and the water pipe, the inlet hole, and the support water passage hole, finally reaching the gap formed between the pressure cap and the water pipe. The conical angle of the pressure cap is pre-adjusted according to the design, and the water flow accelerates and sprays out at this point, forming a uniform water film. The height and shape of the water film are determined by the water pump pressure, the pressure cap angle, and the distribution of the inlet holes.
[0125] Water film effect: Multiple self-lifting water film devices work simultaneously, with the water films cooperating with each other to create a spectacular fountain landscape. At the same time, the colored lighting system changes color and brightness in rhythm with the music, and the light shines through the water film to create a colorful visual effect, providing hotel guests with a beautiful audio-visual feast.
[0126] When the water spray stops
[0127] Water pump stops: After the fountain show ends, the water pump stops supplying water, and the water pressure in the lower outer pipe disappears.
[0128] Automatic reset: Under its own weight, the lifting component slides smoothly down the inner wall of the upper outer pipe and returns to its initial position. The nozzle is then hidden at the bottom of the fountain, ensuring that the water in the pool returns to calm and maintaining the beauty and safety of the landscape.
[0129] System standby: The device is in standby mode, ready to start up at any time. The entire process requires no additional power or complex control; it is completed automatically using hydraulic and gravity power. It has a simple structure, stable operation, and low maintenance costs.
[0130] By adopting the above-disclosed technical solution of this utility model, the following beneficial effects are obtained:
[0131] Automatic lifting function
[0132] Principle: The device uses water power to drive the lifting component. When spraying water, the water flow enters the lower outer pipe from the inlet, pushing the lower block and causing the lifting component to rise, thus extending the nozzle to complete the spraying. When spraying water stops, the water pump shuts off, and the lifting component descends under its own gravity, retracting the nozzle.
[0133] Benefits: Eliminating the need for external power and complex control systems simplifies equipment structure, reduces costs, and improves reliability. Simultaneously, the sprinklers automatically retract to avoid affecting the aesthetics of the ground or water surface, maintaining the cleanliness and harmony of the plaza or landscape pool and enhancing the overall landscape effect.
[0134] Improved aesthetics
[0135] Principle: When not spraying water, the nozzle is hidden inside the lower outer pipe and is flush with the ground of the square or the water surface of the landscape pool.
[0136] Effects: In plazas, it avoids the nozzles disrupting the surface and affecting pedestrian movement. In landscape pools, it keeps the water surface clean, enhances the natural beauty of the landscape, and makes the fountain a highlight rather than a visual distraction.
[0137] Enhanced security
[0138] Principle: When not in operation, the nozzle is hidden inside the lower outer pipe, below the ground or water surface.
[0139] Effects: Effectively prevents pedestrians from tripping or colliding with the nozzles, reducing the risk of accidents and providing a safe and relaxing environment for the public. It is especially suitable for places with high traffic, such as squares, parks and tourist attractions.
[0140] Highly adaptable
[0141] Principle: The pressure cap is designed in a conical shape with an adjustable angle, and it is connected to the lead screw via a thread, making it easy to disassemble and replace.
[0142] Effects: It meets the design requirements of different fountain landscapes, realizes diverse water film shapes and effects, enhances the aesthetics of the fountain, enables the device to be widely used in various scenarios, and enhances its market competitiveness.
[0143] Long service life
[0144] Principle: The filter screen is located at the bottom of the lower outer pipe to filter impurities in the water, preventing clogging of the inlet or damage to the sealing components. Meanwhile, the slider is made of wear-resistant material to ensure stable sliding of the lifting components and reduce wear.
[0145] Effects: Effectively protects the internal structure of the device, reduces the risk of failure, extends service life, reduces maintenance costs and frequency, and ensures long-term stable operation.
[0146] Easy to install and maintain
[0147] Principle: The bottom of the lower outer pipe is equipped with a mounting base for fixing the device. A sealing gasket is provided at the connection between the water inlet and the water supply pump to ensure a tight seal.
[0148] Effects: The mounting base secures the device firmly, and the sealing gasket prevents leakage, ensuring normal operation. When maintenance is required, components such as the pressure cap can be disassembled and replaced for easy adjustment and repair, minimizing impact on fountain use. The overall design prioritizes ease of installation and maintenance, enhancing the user experience.
[0149] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
