Description

Technical Field

[0001] This invention relates to a device that allows a two-dimensional nozzle water column to remain at any point on a three-dimensional sphere, or to rotate continuously and infinitely, or to oscillate back and forth, without the occurrence of wire entanglement, pulling, or breakage. It is a continuously rotating synchronously powered two-dimensional water feature nozzle and its rotation method, belonging to the field of water feature nozzle manufacturing, installation, and debugging technology. Background Technology

[0002] CN2744420Y, entitled "CNC Universal Swing Nozzle for Musical Fountains," describes a CNC universal swing nozzle for musical fountains designed to address the limitation of known nozzles that cannot independently swing in any direction within three-dimensional space. It consists of a stepper motor-driven rotary control mechanism rotating in a horizontal plane and a stepper motor-driven rotary control mechanism rotating in a vertical plane relative to the horizontal plane, comprising a worm gear, worm shaft, fixed joint, and moving joint. The key feature is that the two stepper motors drive the two rotary control mechanisms independently. The horizontal rotary control mechanism drives the vertical rotary control mechanism mounted on it to rotate 360° along its centerline, which in turn drives the nozzle mounted on it to rotate 360° along its centerline. Under the control of the two rotary control mechanisms, the CNC universal swing nozzle for musical fountains can move independently or in conjunction.

[0003] CN2724853Y, entitled "CNC Water Feature Performance Device with Pre-editing Function," comprises a computer host equipped with music signal processing and control software and several CNC mechanisms. Each CNC mechanism includes: a stepper motor driver controlled by the computer host, a stepper motor connected to the driver, a water conveying device connected to the stepper motor, and nozzles connected to the output end of the water conveying device. The water conveying device includes: a horizontal water channel, a vertical water channel, and a transmission mechanism for rotating and outputting water from the horizontal and vertical water channels. This invention features a computer host equipped with music signal processing and control software, which can pre-extract and process digital signals of selected classic musical pieces, making the water movements more closely match the musical emotions, synchronizing water movement changes with musical rhythm, and more fully expressing the musical connotations. This application can be widely applied to various artificial water features.

[0004] CN2709025Y, entitled "A Swinging Fountain Device," relates to a swinging fountain device, particularly a swinging device capable of simultaneously or independently swinging / rotating in intersecting two-dimensional directions to achieve arbitrary changes in three-dimensional patterns. Its characteristic feature is that the water nozzles are mounted on a swinging water supply frame composed of intersecting inlet and outlet pipe sections. The inlet and outlet pipe sections are connected by a rotating joint to form water communication and rotatability. Each inlet and outlet pipe section is driven by its own motor to swing / rotate around its respective axis. The water nozzles are arranged parallel or obliquely to the outlet pipe section. This allows the nozzles to achieve two independent or combined movements of rotation and swinging in the two-dimensional direction, enabling the nozzles to produce more three-dimensional water spray patterns. Especially by using a motor with controllable rotation angle, rotating via a worm gear and worm shaft, and coupled with program control, the nozzles can be made to swing / rotate arbitrarily at any position, producing even more three-dimensional water spray patterns.

[0005] The shortcomings of the above-mentioned technology are as follows: the lower base can only rotate within a limited angle (generally within 360 degrees) on the horizontal plane. When the lower base rotates continuously, the wires of the upper base motor and the origin detection sensor device inevitably become entangled on the lower base, causing the wires to break due to entanglement and pulling. To avoid such situations, the rotation range of the lower base on the horizontal plane is artificially limited, causing it to swing back and forth within a limited angle (generally within one revolution of 360 degrees), thus preventing continuous rotation beyond 360 degrees. This significantly reduces the effectiveness of the water feature. Summary of the Invention

[0006] The first objective of this invention is to design a device that allows the water jet from the nozzle to remain at any point on a three-dimensional sphere, or to rotate or oscillate continuously indefinitely, without the occurrence of wire entanglement, pulling, or breakage. This device is a continuously rotating, synchronously powered two-dimensional water feature nozzle that can rotate more than 360° or oscillate less than 360° indefinitely in two typical planes, either vertical or horizontal, without the occurrence of wire entanglement, pulling, or breakage.

[0007] The second objective of this invention is to provide a method for the continuous rotation of a continuously rotating synchronously powered two-dimensional water feature nozzle.

[0008] Design Scheme: To achieve the above design objectives, 1. A conductive slip ring is mounted on the drive shaft of the lower base to drive the upper base, or a conductive slip ring is mounted on the water inlet / outlet pipe of the lower base. The use of a through-hole slip ring design is one of the technical features of this invention. The purpose of this is that the conductive slip ring falls under the category of electrical contact sliding connection applications. It consists of an elastic material (brush), a sliding contact surface material (conductive ring), insulating material, bonding material, a combined bracket, precision bearings, a dust cover, and other auxiliary components. The brush is made of a precious metal alloy and is in a "II" shape with symmetrical double contact with the conductive ring groove. Signals and current are transmitted through the elastic pressure of the brush and the sliding contact with the conductive ring groove. In this application, when the upper base rotates continuously for 360 degrees without restriction, the wires need to be connected to the motor of the rotating upper base. To avoid wire tangling, an electrical rotating connector (electric slip ring) is used to transmit power and signals, achieving both 360-degree continuous rotation without restriction and solving the problem of wire tangling. 2. The conductive slip ring is designed to be waterproof. The conductive slip ring sealing shell is integrated with the lower base, ensuring concentricity between the entire conductive slip ring sealing shell, the lower base shell, the drive shaft, the perforated slip ring rotor, and the conductive slip ring dynamic seal. This is the second technical feature of this invention. The purpose of this design is that, since this application involves underwater operation (i.e., the patent operates underwater), and water is a conductor, only by designing the conductive slip ring as waterproof or designing the working cavity of the conductive slip ring as a waterproof sealing area can it be used in this application. Therefore, the conductive ring surface is covered with waterproof material, and the rotating contact surface between the rotor and stator in the conductive slip ring has a dynamically fitted waterproof structure, or the working cavity of the conductive slip ring is waterproofed and sealed.

[0009] The technical solution adopted by this invention to achieve its first objective is: a continuously rotating, synchronously powered two-dimensional water feature nozzle, comprising an upper base and a lower base. A geared motor located in the lower base drives the inlet and outlet water pipes and the upper base to rotate. The inlet and outlet water pipes of the lower base are equipped with conductive slip rings, and the output terminal of the conductive slip ring signal circuit is connected to the input terminal of the controller signal circuit of the motor in the upper base. This water feature nozzle, by setting conductive slip rings on the inlet and outlet water pipes between the lower and upper bases, transmits power and signals through the conductive slip rings, avoiding wire entanglement, thus achieving both unrestricted 360-degree continuous rotation and solving the problem of wire entanglement.

[0010] Preferably, the conductive slip ring is a waterproof through-hole conductive slip ring. Using a waterproof through-hole slip ring ensures unrestricted 360-degree rotation of the water feature nozzles and the transmission of power and control signals. Preferably, the conductive ring portion of the through-hole conductive slip ring is the rotor, and the brush portion is the stator. The rotor rotates synchronously with the inlet and outlet water pipes of the lower base, while the stator is fixed to the lower base housing. The conductive slip ring can be configured to rotate using either the brush portion or the conductive ring itself; whether the brush acts as the rotor or the stator depends on the slip ring installation method. Typically, the conductive ring acts as the rotor, and the brush acts as the stator.

[0011] Preferably, the conductive slip ring is bidirectionally rotatable. Generally, the conductive ring portion is the rotor, and the brush portion is the stator. Since the slip ring is bidirectionally rotatable, it doesn't matter whether the brush portion or the conductive ring rotates; whether the brush or the conductive ring acts as the rotor depends on the slip ring's mounting method.

[0012] Preferably, the water inlet and outlet pipes include a lower base water outlet pipe and an upper base water inlet pipe. The conductive slip ring is installed on either the lower base water outlet pipe or the upper base water inlet pipe, and a waterproof sealing device is provided on the outside of the conductive slip ring. Regardless of whether the conductive slip ring is installed on the lower base water outlet pipe or the upper base water inlet pipe, its effect and function are the same, both solving the problem of tangling of the upper base motor and signal wires in the prior art. The water inlet and outlet pipes include a lower base water outlet pipe and an upper base water inlet pipe, which are connected by flanges or other pipe joints. The conductive slip ring can be installed on either the lower base water outlet pipe or the upper base water inlet pipe. The conductive slip ring installed on the upper and lower base water inlet and outlet pipes contains a conductive ring. The signal circuit output terminal of the conductive ring is connected to the signal circuit input terminal of the motor controller in the upper base, and the conductive ring rotates synchronously with the upper base, sliding to draw power to supply power to the upper base motor controller and transmit signals to the controller, fundamentally solving the problem of tangling of the upper base motor and signal wires in the prior art. The conductive slip ring is externally equipped with a waterproof sealing device. Since this application involves underwater operation, and water is a conductor, only a waterproof conductive slip ring designed as such or a working cavity designed to withstand high pressure and be waterproof and sealed can be used in this application. Therefore, the conductive ring surface is covered with waterproof material, and the rotating contact surface between the rotor and stator in the conductive slip ring is equipped with a dynamic fit waterproof structure, or the working cavity of the conductive slip ring is waterproof and sealed.

[0013] Preferably, the waterproof sealing device includes an upper sealing seat, a sealing shell, a lower sealing seat, and an oil seal. The inlet and outlet water pipes, the upper sealing seat, the sealing shell, and the lower sealing seat are coaxially arranged with the drive shaft of the lower base. The oil seal is located between the outer diameter of the upper sealing seat and the inner diameter of the sealing shell, and between the outer diameter of the inlet and outlet water pipes and the inner diameter of the lower sealing seat. The oil seal and the inner diameter of the sealing shell, and the oil seal and the outer diameter of the inlet and outlet water pipes, form a dynamic seal. A bearing or copper sleeve with a clearance dynamic fit is also provided between the outer diameter of the upper sealing seat and the inner diameter of the sealing shell to guide the rotation of the inlet and outlet water pipes. The oil seal is a skeleton oil seal. The waterproof sealing device preferably includes an upper sealing seat, a sealing shell, a lower sealing seat, and an oil seal. The inlet and outlet water pipes, the upper sealing seat, the sealing shell, and the lower sealing seat are coaxially arranged with the drive shaft of the lower base, i.e., concentricity is consistent. This structure is to ensure reduced rotational resistance, improved rotational stability, sealing performance, and extended service life when the two-dimensional water feature nozzle rotates. Since the conductive slip ring contains a stator and a rotor, and the rotor needs to rotate, the conductive slip ring seal requires a dynamic seal. The bearings and copper bushings that guide the rotation of the inlet and outlet water pipes have a clearance dynamic fit. This supports the inlet and outlet water pipes and the upper base, guiding their rotation and reducing frictional resistance. Ordinary skeleton oil seals have a pressure resistance of only about 0.03MPa to 0.05MPa, generally less than the pump head, and cannot meet the sealing requirements. Pressure-resistant skeleton oil seals, on the other hand, can withstand pressures as high as 0.3MPa to over 1MPa. Therefore, pressure-resistant skeleton oil seals are preferred for the end that bears the pump pressure. These seals have a higher pressure resistance than ordinary pump heads and a longer service life.

[0014] Preferably, the upper sealing seat is integrated with the water outlet pipe of the lower base or the water inlet pipe of the upper base, and a bearing seat or a copper sleeve seat is integrally provided on the sealing shell. The lower sealing seat is integrated with or separate from the sealing shell. This structure, which integrates the upper sealing seat with the water outlet pipe of the lower base or the water inlet pipe of the upper base, and the lower sealing seat with or separate from the sealing shell, ensures coaxiality while meeting sealing and waterproofing requirements and reducing friction. The conductive slip ring is designed as a waterproof conductive ring, achieving not only water-contact power supply but also underwater water-contact power supply.

[0015] Preferably, the output port of the rotor signal circuit of the conductive slip ring is located on the upper sealing seat, and the input port of the stator signal circuit of the conductive slip ring is located at the bottom of the lower sealing seat or on the side of the sealing shell. The preferred positions for the conductive slip ring's input and output are: the rotor output port passes through the upper sealing seat, i.e., it is installed inside the inner diameter of the upper oil seal; the stator input port passes through the bottom of the lower sealing seat or the side of the sealing shell, i.e., it is installed outside the outer diameter of the lower oil seal. This is to avoid wire tangling.

[0016] The technical solution adopted by this invention to achieve its second objective is as follows: a method for rotating a continuously rotating synchronously powered two-dimensional water feature nozzle. The lower base, driven by a lower base servo motor or a lower base reducer motor, drives the inlet and outlet water pipes, causing the upper base and the brush or electric ring portion of the conductive slip ring fixed on the lower base's inlet and outlet water pipes to rotate synchronously. The signal circuit output line of the electric ring portion or brush portion is connected to the input terminal of the motor controller signal circuit in the upper base and supplies power to the motor in the upper base while rotating synchronously with the upper base. The lower base, driven by a lower base servo motor or a lower base reducer motor, drives the inlet and outlet water pipes, causing the upper base and the brush or electric ring portion of the conductive slip ring fixed on the lower base's inlet and outlet water pipes to rotate synchronously, while the brush portion remains stationary. The signal circuit output line of the electric ring portion or brush portion is connected to the input terminal of the motor controller signal circuit in the upper base and supplies power to the motor in the upper base while rotating synchronously with the upper base. The motor and signal input terminals of the electric ring portion or brush portion are connected to the power supply and control output lines.

[0017] Preferably, the geared motor refers to a stepper motor driving a speed reducer. A geared motor is an integrated unit of a stepper motor and a speed reducer.

[0018] The beneficial effects of this invention are as follows: Compared with the prior art, this invention has two advantages: First, the drive shaft and inlet / outlet water pipes in the lower base drive the upper base to rotate. The inlet / outlet water pipes of the upper and lower bases are equipped with conductive slip rings containing conductive rings. The signal circuit output terminal of the conductive ring is connected to the signal circuit input terminal of the motor controller in the upper base. The conductive ring rotates synchronously with the upper base, making sliding contact to draw power and supply power to the upper base motor controller and transmit signals to the controller. This fundamentally solves the problem of tangling of the upper base motor and signal lines in the prior art. Second, the conductive slip ring is designed to be waterproof, which not only achieves the purpose of drawing power through water but also achieves the purpose of drawing power through water underwater.

Detailed Implementation

[0023] Example 1:

[0024] See attached document Figure 1 A continuously rotating synchronously powered two-dimensional water feature nozzle includes an upper base 2 and a lower base 1. A drive shaft 4 and a reduction motor 5 located in the lower base 1 drive the inlet and outlet pipes 7 to rotate the upper base 2. The reduction motor 5 is composed of a stepper motor driving a reducer. The inlet and outlet pipes 7 include an outlet pipe 71 in the lower base and an inlet pipe 72 in the upper base. In this embodiment, a conductive slip ring 3 is installed on the outlet pipe 71 in the lower base 1, and the signal circuit output terminal of the conductive slip ring 3 is connected to the signal circuit input terminal of the motor 6 controller in the upper base 2. The conductive slip ring 3 is a waterproof through-hole conductive slip ring, and a waterproof sealing device is provided on the outside of the conductive slip ring 3. The waterproof sealing device includes an upper sealing seat 8, a sealing housing 9, a lower sealing seat 10, and an oil seal 11. The lower machine base water outlet pipe 71, the upper sealing seat 8, the sealing housing 9, and the lower sealing seat 10 are coaxially arranged with the drive shaft 4 of the lower machine base 1. The oil seal 11 is located between the outer diameter of the upper sealing seat 8 and the inner diameter of the sealing housing 9, and between the outer diameter of the lower machine base water outlet pipe 71 and the inner diameter of the lower sealing seat 10 (see...). Figure 2 The oil seal 11 and the inner diameter of the sealing shell 9, as well as the oil seal 11 and the outer diameter of the water inlet pipe 72 of the upper base, form a dynamic seal. A bearing 12, with a clearance dynamic fit, is also provided between the outer diameter of the upper sealing seat 8 and the inner diameter of the sealing shell 9 to guide the rotation of the water inlet and outlet pipes. Alternatively, a copper sleeve or other structural material can be used to guide the rotation of the water inlet and outlet pipes with a clearance dynamic fit. The upper sealing seat 8 and the water outlet pipe 71 of the lower base are integrally formed. A bearing seat 13 is integrally formed on the sealing shell 9, and the lower sealing seat 10 is integrally formed with the sealing shell 9.

[0025] The conductive ring 3 is the rotor 31, and the brush part is the stator 32. The conductive ring 3 rotates bidirectionally; whether the brush part rotates or the conductive ring rotates makes no difference. Whether the brush acts as the rotor or the stator depends on the installation method of the conductive ring. Typically, the conductive ring acts as the rotor 31, and the brush acts as the stator 32. The rotor 31 rotates synchronously with the water inlet pipe 72 of the lower base 1, and the stator 32 is fixed inside the sealing housing 9 of the lower base 2 and remains stationary. The output port of the signal circuit of the rotor 31 of the conductive slip ring 3 is located on the upper sealing seat 8, and the input port of the signal circuit of the stator 32 of the conductive slip ring 3 is located at the bottom of the lower sealing seat 10 or on the side of the sealing housing 9.

[0026] Based on Embodiment 1, a method for rotating a continuously rotating synchronously powered two-dimensional water feature nozzle is provided. The lower base 1 drives the drive shaft 4 via a lower base reduction motor 5, causing the upper base 2 and the brush portion or conductive ring portion of the conductive slip ring 3 fixed on the lower base water outlet pipe 71 of the lower base 1 to rotate synchronously. That is, since the conductive slip ring 3 rotates bidirectionally, it makes no difference whether the brush portion or the conductive ring portion rotates. Whether the brush or the conductive ring acts as the rotor depends on the slip ring installation method. Therefore, in this application, the signal circuit output line of the conductive ring portion or brush portion of the conductive slip ring 3 is connected to the signal circuit input terminal of the motor 6 controller in the upper base 2 and rotates synchronously with the upper base 2, simultaneously supplying power to the motor 6 in the upper base. Typically, the conductive ring must act as the rotor 31, and the brush as the stator 32.

[0027] This continuously rotating synchronously powered two-dimensional water feature nozzle uses a waterproof through-hole conductive slip ring 3. Because the conductive slip ring 3 contains brushes that carry voltage and current, and water is a conductor, water cannot enter the brushes. Therefore, the conductive slip ring 3 must be strictly sealed and waterproof. While many existing sealing technologies can be used, in modern fountains, the water jet height often reaches tens to hundreds of meters. Therefore, the conductive slip ring 3 must withstand the water pressure of the pump's head of tens to hundreds of meters. In other words, it can be considered that the conductive slip ring 3 operates underwater at depths of tens to hundreds of meters. Simultaneously, the fountain's water flow rate is also very high. Furthermore, the conductive slip ring 3 contains a stator 32 and a rotor 31, which need to rotate. Therefore, the conductive slip ring must operate in a dynamically sealed environment at depths of tens to hundreds of meters. The wire connecting one end of the stator 32 is introduced into the sealed housing 9 of the three-way base with a waterproof sealed cable through the sealing screw hole and sealed with sealing material. It is designed to be fixed. The cable connecting one end of the rotor 31 needs to rotate with the rotor 31. The waterproof sealed cable connecting one end of the rotor 31 is led out after being sealed with sealing material through the sealing screw hole of the upper sealing seat 8. Therefore, the sealing and waterproofing of the conductive slip ring 3 under high pressure and the sealing of the cable entering and exiting are also very important.

[0028] This invention employs a skeleton oil seal for dynamic sealing, and the rotating part also uses a dynamic seal. The oil seal can be a pressure-resistant skeleton oil seal for dynamic sealing. Since ordinary skeleton oil seals only withstand pressures of around 0.03 MPa to 0.05 MPa, which is generally less than the pump head, they cannot meet the sealing requirements. In contrast, pressure-resistant skeleton oil seals can withstand pressures as high as 0.3 MPa to over 1 MPa, thus their pressure resistance is generally greater than the pump head. If the pump supply pressure is high, the lower sealing seat 10 and oil seal 11 will withstand the pressure of water from a pump head of tens to hundreds of meters. Two pressure-resistant skeleton oil seals can be stacked and combined for dynamic sealing to ensure a sufficient seal.

[0029] Example 2:

[0030] exist Figure 3In the illustrated embodiment, a continuously rotating synchronously powered two-dimensional water feature nozzle includes an upper base 2 and a lower base 1. A drive shaft 4 and a reduction motor 5 located within the lower base 1 drive the inlet and outlet pipes 7 and the upper base 2 to rotate. The reduction motor 5 is composed of a stepper motor driving a reducer. The inlet and outlet pipes 7 include an outlet pipe 71 from the lower base and an inlet pipe 72 from the upper base. In this embodiment, a conductive slip ring 3 is mounted on the inlet pipe 72 of the upper base of the lower base 1, and the signal circuit output terminal of the conductive slip ring 3 is connected to the signal circuit input terminal of the motor 6 controller in the upper base 2. The conductive slip ring 3 is a waterproof through-hole conductive slip ring, and a waterproof sealing device is provided on the outside of the conductive slip ring 3. The waterproof sealing device includes an upper sealing seat 8, a sealing shell 9, a lower sealing seat 10, and an oil seal 11. The upper base water inlet pipe 72, the upper sealing seat 8, the sealing shell 9, and the lower sealing seat 10 are coaxially arranged with the drive shaft 4 of the lower base 1. The oil seal 11 is located between the outer diameter of the upper sealing seat 8 and the inner diameter of the sealing shell 9, and between the outer diameter of the upper base water inlet pipe 72 and the inner diameter of the lower sealing seat 10. The oil seal 11 and the inner diameter of the sealing shell 9, and the oil seal 11 and the outer diameter of the upper base water inlet pipe 72 form a dynamic seal. A copper sleeve with a clearance dynamic fit is also provided between the outer diameter of the upper sealing seat 8 and the inner diameter of the sealing shell 9, and between the outer diameter of the upper base water inlet pipe 72 and the inner diameter of the lower sealing seat 10 to guide the rotation of the inlet and outlet pipes. The upper sealing seat 8 and the upper base water inlet pipe 72 are integrally formed, and the sealing shell 9 is integrally formed with a copper sleeve seat. The lower sealing seat 10 and the sealing shell 9 are separate.

[0031] The conductive ring 3 has a conductive ring portion that forms the rotor 31 and a brush portion that forms the stator 32. The conductive ring 3 rotates bidirectionally; whether the brush portion rotates or the conductive ring rotates makes no difference. Whether the brush acts as the rotor or the stator depends on the installation method of the conductive ring. Typically, the conductive ring acts as the rotor, and the brush acts as the stator. The rotor rotates synchronously with the water inlet pipe 72 of the lower base 1, while the stator is fixed inside the sealing housing 9 of the lower base and remains stationary. The output port of the signal circuit of the rotor 31 of the conductive slip ring 3 is located on the upper sealing seat 8, and the input port of the signal circuit of the stator 32 of the conductive slip ring 3 is located at the bottom of the lower sealing seat 10 or on the side of the sealing housing 9.

[0032] Based on Embodiment 2, a method for rotating a continuously rotating synchronously powered two-dimensional water feature nozzle is provided. The lower base 1 drives the drive shaft 4 via the lower base reduction motor 5, causing the upper base 2 and the brush portion or conductive ring portion of the conductive slip ring 3 fixed on the upper base water inlet pipe 72 to rotate synchronously. That is, since the conductive slip ring 3 rotates bidirectionally, it makes little difference whether the brush portion or the conductive ring portion rotates. Whether the brush or the conductive ring acts as the rotor depends on the slip ring installation method. Therefore, in this application, the signal circuit output line of the conductive ring portion or brush portion of the conductive slip ring 3 is connected to the signal circuit input terminal of the motor 6 controller in the upper base 2 and rotates synchronously with the upper base 2, simultaneously supplying power to the motor 6 in the upper base. Typically, the conductive ring must act as the rotor, and the brush as the stator.

[0033] In this embodiment, the upper base water inlet pipe 72 houses the conductive slip ring and sealing device. Therefore, the upper base water inlet pipe 72 is relatively long, increasing the processing difficulty. It can be assembled in two sections. The lower section of the upper base water inlet pipe 72 is coaxially formed with the upper sealing seat 8, the sealing shell 9, the lower sealing seat 10, and the oil seal 11. The upper section of the upper base water inlet pipe 72 is formed with the upper base 2. The upper and lower sections of the upper base water inlet pipe 72 are connected by flanges or other pipes.

[0034] Although the above embodiments provide a relatively detailed textual description of the design concept of the present invention, these textual descriptions are merely simple descriptions of the design concept of the present invention and are not intended to limit the design concept of the present invention. Any changes or alterations to the installation position, as long as they do not exceed the combination, addition, or modification of the design concept of the present invention, fall within the protection scope of the present invention.
