At the same time, in order to improve the dynamic effect of the water curtain and enhance the viewing experience of the water curtain at night, the size of the water curtain water flow is often adjusted by a motor, so that the water flow size changes continuously at a set frequency, and then the LED light output is controlled by the corresponding relationship between the frequency of the water flow size and the frequency of the PWM signal, so as to achieve the illusion of the water flow flowing downstream, upstream, and suspended motionless through the naked eye.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] refer to Figure 1 and Figure 2 As shown, an optical water curtain device with adaptive water speed includes a water supply part 1 and at least one water collection part 2; it also includes a physical rotor 3, a control module 4, an LED light-emitting module 5 electrically connected to the control module 4, and a speed detection module 6.

[0022] Specifically, the water supply part 1 is connected with the water collection part 2, and a plurality of water outlets are provided on one side of the water collection part 2. The water in the water supply part 1 flows down along the water outlets on the water collection part 2 and forms a water curtain 7. The water outlets are arranged in a linear array on one side of the water collection part 2. Due to the effect of gravity, the water in the water supply part 1 flows down through the water outlets of the water collection part 2, forming a water curtain along the water outlets.

[0023] The water outlet is provided with a nozzle, and the water in the water collecting part 2 is sprayed through several nozzles to form the water curtain. By providing the nozzles to spray water flow, the formation of the water curtain can be further enhanced, forming a more delicate and dense water curtain effect.

[0024] The LED light emitting module 5 is arranged at one side of the water outlet, and the light emitted by the LED light emitting module 5 is irradiated onto the water curtain. The LED light emitting module 5 includes a plurality of LED light emitters, and the LED light emitters are all electrically connected to the control module 4.

[0025] By irradiating the light emitted by the LED illuminator onto the water curtain, due to the refraction and scattering effects of the light, a beautiful optical effect will be presented on the water flow, thereby forming the visual effect of an optical water curtain. Then, the PWM signal frequency of the LED light emitting module 5 can be adjusted by the control module 4, and the flashing frequency or the rate of brightness change of the LED illuminator can be changed, so that the light and shadow effect presented on the optical water curtain changes. In actual use, by setting the output PWM signal frequency, the water flow of the optical water curtain can be presented as downstream, upstream or suspended motionless under naked eye observation.

[0026] The physical rotor 3 is located in the water curtain and rotates under the impact of the water flow of the water curtain 7. The physical rotor 3 does not require a complex installation and driving structure, nor does it require electric energy drive, and the cost is low. When the water flow of the water curtain 7 rushes towards the physical rotor 3, the physical rotor 3 rotates under the impact of the water flow, and the water flow speed is proportional to the rotation speed of the physical rotor 3. At the same time, the rotation speed of the physical rotor 3 is proportional to the frequency of the change in the size of the water flow.

[0027] The speed detection module 6 is used to detect the speed of the physical rotor 3 and send the data to the control module 4; the control module 4 is used to adjust the signal frequency of the PWM signal driving the LED light-emitting module 5 according to the speed of the physical rotor 3, and switch the 5 lighting effects of the LED light-emitting module. In this embodiment, the control module 4 pre-stores a correspondence between the speed of several physical rotors 3 and the PWM signal frequency. When the control module 4 receives the real-time speed of the physical rotor 3 detected by the speed detection module 6, it outputs the PWM signal frequency corresponding to the real-time speed according to the pre-stored correspondence between the speed of the physical rotor 3 and the PWM signal frequency, and drives the LED light-emitting module 5 to switch to the corresponding lighting effect, so as to achieve the change of the optical water curtain light and shadow effect.

[0028] The rotation speed detection module 6 is a rotation speed detection circuit, and the rotation speed detection circuit includes a rotation speed detection sensor, and the rotation speed detection sensor is used to detect the rotation speed of the physical rotor 3 .

[0029] Specifically, a magnet is provided on the physical rotor 3, and the speed detection sensor is a Hall sensor. The Hall sensor senses the change of the magnetic field of the magnet as the physical rotor rotates, and then obtains the speed of the physical rotor. The Hall sensor has a fast response time and high detection accuracy. When the magnet rotates as the physical rotor 3 rotates, it periodically approaches the Hall sensor. The Hall sensor senses the change of the magnetic field of the magnet as the physical rotor 3 rotates, and outputs a corresponding electrical signal. According to the electrical signal output by the Hall sensing device, the number of revolutions of the physical rotor 3 is determined, and then the speed of the physical rotor 3 is obtained.

[0030] Preferably, the optical water curtain system also includes a water reservoir 8, which is used to recover the water of the water curtain 7 falling through the water outlet, so as to realize the recycling and reuse of water resources. The water flow is buffered and decelerated when falling into the water reservoir 8, which can reduce the noise generated by the impact of the water flow and reduce the impact of the system operation on the surrounding environment.

[0031] The optical water curtain system also includes a water pump 9 electrically connected to the control module 5, one end of the water pump 9 is connected to the water supply part 1, and the other end is connected to the water collection part 2 through a drain pipe 10, and a solenoid valve 11 electrically connected to the control module 5 is provided on the drain pipe 10. The opening and closing of the solenoid valve 11 is controlled by the control module 5, thereby controlling the start and stop of the water supply from the water supply part 1 to the water collection part 2. The outflow size and rhythm of the water flowing into the water collection part 2 can also be controlled by controlling the opening and closing degree of the solenoid valve 11.

[0032] Example 2

[0033] The adaptive optical water curtain system provided in Example 2 has the same structure as that in Example 1, except that the speed detection sensor is a laser speed sensor, which is used to detect the reflection frequency of the laser signal emitted to the physical rotor 3, thereby obtaining the speed of the physical rotor 3. The laser speed sensor emits a laser signal to the surface of the physical rotor 3, and the laser signal is reflected by the surface of the physical rotor and received by the laser speed sensor. The laser speed sensor obtains the speed information of the physical rotor 3 according to the frequency change of the received laser signal.

[0034] A reflective sticker is provided on the physical rotor 3, and the reflective sticker is used to enhance the reflection intensity of the laser signal. The reflective sticker can enhance the reflection intensity of the laser signal, so that the laser signal reflected by the physical rotor 3 is more stable, less susceptible to changes in ambient light or other interference, and improves the accuracy of speed detection.

[0035] The utility model provides an optical water curtain device with adaptive water speed, which uses a physical rotor 3 to rotate under the impact of a water curtain 7, so as to feedback the size and change frequency of the water flow of the water curtain 7; and then detects the speed of the physical rotor 3 to control the light-emitting effect of the switching LED light-emitting module. It does not need to set a motor to control the size of the water flow, has a simple structure, and has low manufacturing and use costs.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
