Description

Technical Field

[0001] This utility model relates to fountain equipment, and more particularly to an integrated dry fountain nozzle device. Background Technology

[0002] Musical fountains can be categorized into dry-land fountains and pool fountains based on their location. Dry-land fountains, on the other hand, place the fountain installation underground, with the nozzles and lighting panels above ground. When water is sprayed, a pump draws water from a pool and supplies it to the appropriate nozzles via pipelines. The water jets are then projected from the nozzles, achieving a visually appealing effect without taking up valuable recreational space. These are typically found in commercial streets, plazas, or shopping malls. There are many types of nozzles, including direct-jet nozzles and rotating nozzles. Rotating nozzles require a separate underground rotating mechanism to select the appropriate nozzle and create the desired water jet pattern. Since fountain performances require many nozzles working together, each fountain has its own associated equipment and piping, making the underground equipment and piping of dry-land fountains very complex and difficult to install and maintain. When a nozzle's equipment or piping malfunctions, the entire fountain show must be stopped and postponed. Maintenance personnel then have to cordon off the area around the fountain, pry up the floorboards, and descend into the pool below to inspect and maintain the equipment. This process is not only time-consuming and cumbersome, but also disrupts the plaza's commercial operations. Therefore, there is an urgent need to design a completely new dry fountain nozzle system.

[0023] The present invention will be further described below.

[0024] Example: An integrated dry sprinkler head device, see [link / reference] Figures 1 to 7 The device includes a nozzle 1, a lamp panel 1, a water outlet connector 5, and a water inlet cylinder 3. The water inlet cylinder 3 is fixedly connected to the lamp panel 1 through the water outlet connector 5. An impeller 9 is provided at the bottom of the water inlet cylinder 3. An inner cylinder 4 is provided inside the water inlet cylinder 3. A guide vane 6 is provided at the top of the inner cylinder 4. The inner cylinder 4 is fixedly connected to the water inlet cylinder 3 through the guide vane 6. A motor 7 that drives the rotating head to rotate and a water pump 8 that drives the impeller 9 to rotate are provided inside the inner cylinder 4. The nozzle 1 is located inside the water outlet connector 5. The motor 7 is fixed to the top of the inner cylinder 4, and its output shaft passes through the inner cylinder 4 and is fixedly connected to the bottom of the nozzle 1. This utility model replaces the existing water inlet pipe with a water inlet cylinder 3, and integrates the motor 7, impeller 9, and water pump 8 into the water inlet cylinder 3. Through the water outlet connector 5, the water inlet cylinder 3, light panel 1, and nozzle 1 are connected as one unit, realizing the integrated design of the nozzle 1 device. Through the integrated design, each nozzle 1 of the fountain is an independent device. Multiple nozzle 1 devices are electrically connected to each other, and can be driven and controlled separately. When installing and maintaining the equipment, if a nozzle 1 fails to spray water, only the individual nozzle 1 device needs to be removed and replaced, which is very convenient and quick, and will not affect the commercial operation of the mall.

[0025] When the nozzle 1 device is working: the entire device is suspended on the floor of the ground by the lamp plate 1. The lower end of the water inlet cylinder 3 is located in the water pool below the ground. The water pump 8 drives the impeller 9 to rotate, drawing water from the pool into the water inlet cylinder 3. The water flows through the impeller 9 into the cavity between the inner cylinder 4 and the water inlet cylinder 3, passes through the guide vanes 6 at the top and enters the water outlet connector 5, and then sprays out from the nozzle 1 to form a fountain.

[0026] Considering the product's versatility design, and to enable the nozzle 1 to rotate, this application incorporates an inner cylinder 4 within the water inlet cylinder 3. The inner cylinder 4 provides a closed space for the installation of the motor 7, ensuring its safe operation. The motor 7 enables the nozzle 1 to rotate, allowing the water sprayed from the nozzle 1 to swirl. Furthermore, this design does not occupy external space in the water inlet cylinder 3 and does not affect the installation of the device.

[0027] To facilitate installation of the entire device above the pool, the diameter of the water inlet cylinder 3 is smaller than that of the lamp plate 1. Only a through hole matching the size of the water inlet cylinder 3 needs to be drilled in the floor to insert the entire nozzle 1 device. Since the lamp plate 1 is larger than the through hole, the entire device can be suspended. When the nozzle 1 malfunctions and needs repair, there is no need to fence off the surrounding area or pry open the floor. Simply remove the entire nozzle 1 device, replace it with a new one, connect the wires, and insert it back through the through hole. The repair process can be completed in minutes, making it very convenient and quick. The corresponding wires are pre-laid on the underside of the floor; during installation, simply plug them into the connector.

[0028] To connect the water inlet pipe to the lamp panel 1, the water outlet connector 5 is a hollow tubular structure with an annular chuck at the upper end. The chuck is mounted on the lamp panel 1, and the connection between the water outlet connector 5 and the lamp panel 1 is achieved through the chuck structure. At the same time, the lamp panel 1 is used to suspend the equipment below on the floor. The lamp panel 1 has a groove that matches the chuck, and the chuck is fixed in the groove of the lamp panel 1 with fastening screws, so that the upper surface of the water outlet connector 5 is flush with the surface of the lamp panel 1, preventing people walking or playing above from tripping over it.

[0029] The upper surface of the nozzle 1 is flush with the upper surface of the lamp panel 1 to prevent the nozzle 1 from being uneven and tripping people walking or playing above. The nozzle 1 is tightly attached to the inner wall of the water outlet connector 5, and the connection surface between the nozzle 1 and the water outlet connector 5 is a smooth surface. The nozzle 1 rotates inside the water outlet connector 5 via the motor 7.

[0030] There are four guide vanes 6, which are centrally symmetrically distributed. The guide vanes 6 are vertically arranged between the water inlet cylinder 3 and the inner cylinder 4, and the upper and lower ends are fixedly connected to the water inlet cylinder 3 and the inner cylinder 4 respectively. The guide vanes 6 serve two purposes: first, to connect the inner cylinder 4 and the water inlet cylinder 3; and second, to divert and guide the water flow, so that the water flow can be smoothly guided to the water outlet connector 5.

[0031] The length of the water inlet cylinder 3 is determined according to the height of the water pool from the ground. As long as it can ensure that the bottom of the water inlet cylinder 3 is always below the water surface of the pool, the bottom of the water inlet cylinder 3 is also provided with a filter protective cover 10 to prevent foreign objects from entering the impeller 9. The filter protective cover 10 can prevent foreign objects from entering the water inlet cylinder 3.

[0032] The output shafts of the motor 7 and the water pump 8 are rotatably connected to the inner cylinder 4 via waterproof sealed bearings, which can prevent water from entering the inner cylinder 4. The side of the water inlet cylinder 3 is provided with an inlet connector 13, which is located between the water inlet cylinder 3 and the inner cylinder 4 and communicates with the inside of the inner cylinder 4. The lamp panel 1 is provided with lamp beads 11 and lamp bead control circuit board. The bottom of the lamp panel 1 is provided with a terminal 12 that is electrically connected to the lamp bead circuit board. The device can be quickly connected to electricity through the inlet connector 13 and the terminal 12.

[0033] As a preferred option, the nozzle 1 can be an existing cast nozzle 1, which is integrally 3D printed from stainless steel material. The nozzle 1 has flow channels printed inside, and its volume is smaller than that of the existing cast nozzle 1.

[0034] This embodiment is a dry spray nozzle 1 with a rotating nozzle 1 function. If the user does not need the nozzle 1 to rotate, the motor 7 can be omitted, which can reduce the equipment cost. Alternatively, the design of the inner cylinder 4 and the motor 7 can be eliminated to form a simplified version of the direct spray dry spray nozzle 1 device.

[0035] If the water pump 8's drive motor has a low waterproof rating, it can be designed inside the inner cylinder 4, with the motor's output shaft passing through the inner cylinder 4 to drive the impeller 9. If the water pump 8 is a submersible pump with a high waterproof rating, it can also be installed outside the inner cylinder 4, simply fixed to the bottom of the inner cylinder 4.

[0036] The above provides a detailed description of the integrated dry sprinkler head device provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, based on the idea of ​​this utility model, there will be changes in the specific implementation and application scope. Changes and improvements to this utility model are possible without exceeding the concept and scope specified in the appended claims. Therefore, the content of this specification should not be construed as a limitation of this utility model.
