Description

Technical Field

[0001] This application belongs to the field of spray equipment technology, and in particular relates to a spray device with a spray angle that can be precisely adjusted. Background Technology

[0002] Energy storage products need to undergo waterproof performance testing during the research and development or manufacturing process to prevent damage to internal components and electronic parts due to water seepage when put into use. Currently, waterproof testing mainly uses spray equipment with uniform array nozzles or swingable nozzles, combined with PLC to adjust the flow rate, pressure and angle, to achieve dual verification of waterproofing under simulated rainstorm level and thermal runaway fire extinguishing.

[0003] However, traditional spraying equipment is often limited by fixed angles or limited mechanical adjustment range, resulting in uneven spray coverage, blind spots, and poor dynamic adjustment capability of the nozzles, making it difficult to meet the needs of precise spraying. This may lead to missed detections due to missing edge dead corners or uneven spraying, thus affecting the test results. Summary of the Invention

[0004] This application provides a spraying device with a precisely adjustable spraying angle, which can solve the problems of uneven spraying coverage, blind spots, and poor dynamic adjustment capability caused by the fixed angle or insufficient mechanical adjustment of traditional spraying devices.

[0005] Based on this, the present invention adopts the following technical solution: This application provides a spray device with a precisely adjustable spray angle, the spray device comprising: Water supply pipe, used to connect to the sprinkler source; Multiple spray components are spaced apart along the length of the water supply pipe. Each spray component has a quick-rotating joint at one end. The water supply pipe has a water outlet corresponding to the spray component. The quick-rotating joint is movably and sealingly connected to the water outlet and can rotate about the water outlet as an axis. A drive component is electrically connected to multiple spray components and is used to control the multiple spray components to spray at multiple angles. The output end of the drive component is connected to a linkage component. Each spray component is provided with a clamp, and the spray component is fixed to the linkage component by the clamp.

[0006] In one embodiment, the spray assembly includes a ball valve, a gauge seat, and a nozzle; The quick-rotary joint is connected to the ball valve, the ball valve is also connected to one end of the gauge seat, the other end of the gauge seat is connected to the nozzle, and the clamp is sleeved on the outer wall of the gauge seat; The ball valve is used to control the on / off state of the corresponding spray assembly.

[0007] In one embodiment, the nozzle is an IPX4 nozzle, an IPX5 nozzle, or an IPX6 nozzle.

[0008] In one embodiment, the spray assembly further includes a pressure gauge mounted on the gauge mount; The pressure gauge is used to detect the water pressure of the corresponding spray assembly; The ball valve is also used to control the water flow rate of the corresponding spray assembly according to the water pressure.

[0009] In one embodiment, the drive assembly includes a power structure, a transmission structure, and a mounting plate; The transmission structure is fixedly connected to the linkage component and the power structure respectively. Both the power structure and the transmission structure are disposed on the top surface of the mounting plate, and the transmission structure is movably connected to the mounting plate.

[0010] In one embodiment, the power structure includes a servo motor and a speed reducer; The input end of the speed reducer is connected to the servo motor, and the output end of the speed reducer is connected to the transmission structure.

[0011] In one embodiment, the transmission structure includes a gear, a rack, and a connecting plate; The gear is fixedly connected to the output end of the power structure, and the rack is fixed to the mounting plate; The connecting plate is fixedly connected to the linkage component and the power structure respectively, and the rack and the gear are meshed together.

[0012] In one embodiment, the drive assembly further includes a guide rail structure; The guide rail structure is fixed to the mounting plate, and the connecting plate is slidably connected to the guide rail structure.

[0014] In one embodiment, the spray coverage of a single spray assembly is ±35°.

[0015] The beneficial effects of this utility model are: The quick-release rotary joint, working in conjunction with a sturdy clamp, provides the spray assembly with a highly efficient and low-resistance rotational freedom, ensuring smooth and unimpeded angle adjustment. The quick-release rotary joint supports continuous rotation of ±35°. Secondly, the drive assembly utilizes high-precision electrical signals to control the spray assembly and its associated mechanisms for precise positioning and stable operation, allowing a single spray assembly to achieve stepless and precise adjustment of any angle within a ±35° range.

[0016] The drive component utilizes a servo motor to provide precise speed and position control signals, and uses a reducer to convert them into a stable output with high torque and low speed, thereby ensuring that the spray assembly and its associated mechanisms are positioned with extreme precision and operate with extreme smoothness.

[0017] By fixing the spray assembly with a clamp, the tension of the spray assembly on the quick-rotary joint is eliminated. At the same time, the quick-rotary joint and the clamp work together to suppress the micro-vibration generated by the drive assembly during power output.

It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] This application provides a spray device with a precisely adjustable spray angle, such as... Figure 1 The diagram shows the overall structure of the spraying device, which includes a water supply pipe 10, multiple spraying components 20, and a drive component 30. The water supply pipe 10 is used to connect to the spraying source to receive the spraying liquid, such as water or other non-corrosive solutions, supplied by the spraying source.

[0026] In this embodiment, the spray assembly 20 has independent controllability and scalability, see [link to documentation]. Figure 1Four spray components 20 are spaced apart along the length of the water supply pipe 10. Of course, there can be other numbers of spray components. The spray range of a single spray component constitutes the smallest coverage unit. Specifically, the spray coverage range of a single spray component is ±35°. The number of spray components 20 can be determined according to the coverage capacity requirements of the spray device. Each spray component 20 has a quick-release rotatable joint 21 at one end. The water supply pipe 10 has a water outlet corresponding to the spray component 20. The quick-release rotatable joint 21 is movably and sealingly connected to the water outlet and can rotate about the water outlet as an axis.

[0027] Specifically, the quick rotary joint 21 adopts a high-speed plug-sealed rotary joint, which mainly achieves unlimited continuous rotation of ±35° through a triple synergistic mechanism of spring energy storage, U-shaped sealing lip, and dynamic lubrication, with a measured leakage rate of less than 1×10. -6 cm³ / s, and meets the requirement of zero leakage after 10,000 rotations.

[0028] In this embodiment, the drive component 30 is electrically connected to multiple spray components 20 to control the multiple spray components 20 to perform multi-angle spraying. Specifically, the drive component 30 can drive a single spray component 20 to achieve milliradian-level precise positioning and millisecond-level response.

[0029] Furthermore, such as Figure 1 As shown, the output end of the drive assembly 30 is connected to the linkage assembly 40. Each spray assembly 20 is equipped with a clamp 22, and the spray assembly 20 is fixed to the linkage assembly by the clamp 21. The clamp 22 provides a rigid mounting reference, eliminates the pulling of the spray assembly 20 on the quick-rotary joint 21, and suppresses the transmission of micro-vibrations of the drive assembly 30 to the spray assembly 20.

[0030] In this embodiment, see Figure 2 The diagram shows the structure of the spray assembly 20, which includes a ball valve 23, a gauge seat 24, and a nozzle 25. A quick-release rotary joint 21 connects to the ball valve 23, which is also connected to one end of the gauge seat 24. The other end of the gauge seat 24 connects to the nozzle 25, and a clamp 22 is fitted onto the outer wall of the gauge seat 24.

[0031] Furthermore, the ball valve 23 is used to control the on / off state of the corresponding spray assembly 20 to ensure the control independence of a single spray assembly 20.

[0032] Furthermore, nozzle 25 is an IPX4 nozzle, an IPX5 nozzle, or an IPX6 nozzle. Specifically, nozzles with different standard interfaces can be selected according to the required IP waterproof rating test. In this embodiment, all nozzles 25 can be nozzles with the same IP waterproof rating or nozzles with different IP waterproof ratings. This embodiment mainly uses a uniform IPX5 standard nozzle.

[0033] Further, see Figure 2 The spray assembly 20 also includes a pressure gauge 26, which is mounted on the pipe gauge seat 24. The pressure gauge 26 is used to detect the water pressure of the corresponding spray assembly 20, and can monitor the spraying effect of a single spray assembly 20 in real time.

[0034] In one possible implementation, the ball valve 22 is also used to control the water flow rate of the corresponding spray assembly 20 based on the water pressure monitored by the pressure gauge 26, that is, to control the water output rate of the nozzle 25.

[0035] In this embodiment, see Figure 3 This is a schematic diagram of the drive assembly 30, which includes a power structure 31, a transmission structure 32, and a mounting plate 33. The transmission structure 32 is fixedly connected to both the linkage assembly 40 and the power structure 31. Both the power structure 31 and the transmission structure 32 are located on the top surface of the mounting plate 33, and the transmission structure 32 is movably connected to the mounting plate 33.

[0036] In one possible implementation, such as Figure 3 As shown, the power structure 31 includes a servo motor 311 and a reducer 312. The input end of the reducer 312 is connected to the servo motor 311, and the output end of the reducer 312 is connected to the transmission structure 32. The servo motor 311 provides precise speed and position control signals, while the reducer 312 converts these signals into a stable output with high torque and low speed.

[0037] In one possible implementation, such as Figure 3 As shown, the transmission structure 32 includes a gear 321, a rack 322, and a connecting plate 323. The gear 322 is fixedly connected to the output end of the power structure; specifically, the gear 322 is connected to the output end of the reducer 312. The rack 322 is fixedly mounted on the mounting plate 33. The connecting plate 323 is fixedly connected to both the linkage assembly 40 and the power structure 31, and the rack 321 and gear 322 are meshed together.

[0038] Furthermore, such as Figure 3 As shown, the drive assembly 30 also includes a guide rail structure 34. Specifically, the guide rail structure 34 is fixed to the mounting plate 33 and has two rails. The bottom of the connecting plate 323 has a slider, which is slidably connected to the guide rail structure 34. The guide rail structure 34 can reduce the friction between the gear 321 and the rack 322 in the transmission structure 32, thereby reducing wear.

[0039] In this embodiment, see Figure 4The diagram shows the structure of the linkage assembly 40, which includes multiple inner chain plates 41 and multiple outer chain plates 42 arranged opposite to each other. Each pair of inner chain plates 41 and each pair of outer chain plates 42 are alternately connected by connecting pins 43, and clamps 22 are fixedly connected to the connecting pins 43. This chain-structured linkage assembly 40 ensures the scalability of the spray assembly 20 during installation, while also providing resistance to impact and vibration.

[0040] Based on the above embodiments, the beneficial effects of this utility model can be obtained as follows: 1. The quick-release rotary joint, working in conjunction with a sturdy clamp, provides the spray assembly with a highly efficient and low-resistance rotational freedom, ensuring smooth and unobstructed angle adjustment. The quick-release rotary joint supports continuous rotation of ±35°. Secondly, the drive assembly utilizes high-precision electrical signals to control the spray assembly and its associated mechanisms for precise positioning and stable operation. This allows a single spray assembly to achieve stepless, precise adjustment of any angle within a ±35° range.

[0041] 2. The drive component utilizes a servo motor to provide precise speed and position control signals, and uses a reducer to convert them into a stable output with high torque and low speed, thereby ensuring that the spray assembly and its associated mechanisms are positioned with extreme precision and operate with extreme smoothness.

[0042] 3. The spray assembly is fixed by clamps to eliminate the pulling of the spray assembly on the quick-rotary joint. At the same time, the quick-rotary joint and the clamps work together to suppress the micro-vibration generated by the drive assembly when power is output.

[0043] 4. The overall structural design is simple and reliable, making it easy to install and modify on the original basis, and the components are easy to replace.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
