Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of nozzle cleaning devices, and more specifically, to a nozzle cleaning device. Background Technology

[0002] In the operation and maintenance of automatic misting systems for solar light poles, clogging of the nozzles and connecting pipes has always been a key pain point affecting the normal operation of the equipment. These systems are mostly used in scenarios such as road greening and plaza cooling. Their misting nozzles and water supply pipelines transport water containing impurities (such as municipal reclaimed water and natural rainwater) for a long time, which is very easy to cause blockage due to scale and silt accumulation, resulting in uneven spraying or even complete failure.

[0003] Current maintenance methods primarily rely on manual cleaning, requiring operators to climb light poles to remove sprinkler heads. Cleaning a single light pole is time-consuming, and working at height poses safety risks. In areas with high installation density (such as urban main roads), manual maintenance is not only inefficient but also wastes energy due to frequent system start-ups and shutdowns. More importantly, hidden blockages inside the pipes are difficult to remove completely manually, often requiring the replacement of the entire pipe section, increasing maintenance costs.

[0004] With the large-scale application of solar light pole misting systems, the limitations of manual cleaning are becoming increasingly apparent. Statistics show that equipment failure rates due to unresolved blockages are high, directly impacting the effectiveness of dust suppression and humidification. Therefore, developing a device that adapts to solar light pole scenarios and enables automatic cleaning of nozzles and pipes has become an urgent need to reduce maintenance costs and improve system reliability. Utility Model Content

[0024] like Figures 1-3 As shown, a nozzle cleaning device according to an embodiment of the present disclosure is illustrated, comprising: A pair of side frames 1 and an outer frame 2, wherein the outer frame 2 is disposed outside the side frames 1; Fixed connection assembly 4, the fixed connection assembly 4 being disposed between the side frames 1; A mobile cleaning component 3 is mounted on the outer frame 2 and the side frame 1. The mobile cleaning assembly 3 includes a pair of guide rods 3-1, which are fixed inside one of the side frames 1. The outer frame 2 is slidably connected inside the outer frame 2. An internal rack 3-2 is provided at the bottom of the upper guide rod 3-1. An ultrasonic generator 3-3 is provided on the side surface of the outer frame 2. A drive motor 3-4 is provided on the side surface of the outer frame 2. A drive gear 3-5 is provided at the output end of the drive motor 3-4. The upper end of the drive gear 3-5 meshes with the internal rack 3-2. A pair of connecting frames 3-6 are provided on the side surface of the outer frame 2. A movable frame 3-7 is vertically and movably connected inside the connecting frame 3-6. An ultrasonic head 3-8 is fitted at the bottom of the movable frame 3-7. A pair of springs 3-9 are fitted on the movable frame 3-7. Supporting slide rods 3-10 are provided at both ends of the bottom of the connecting frame 3-6. The lower end of the supporting slide rod 3-10 is higher than the ultrasonic head 3-8.

[0025] In some examples, in order to achieve comprehensive and efficient cleaning of the water pipes and nozzles of the light poles and to meet the long strip cleaning needs of outdoor light poles, a mobile cleaning component 3 is designed. This component has a pair of guide rods 3-1 fixed in parallel inside one of the side frames 1. The outer frame 2 is directly slidably connected to the guide rods 3-1 through the sliding sleeve structure on the inner wall. The guide rods 3-1 provide a stable moving track for the outer frame 2, ensuring that the outer frame 2 only moves along the length of the guide rods 3-1 and avoids deviation during the cleaning process.

[0026] The internal rack 3-2 located at the bottom of the guide rod 3-1 at the upper end meshes with the drive gear 3-5 at the output end of the drive motor 3-4 on the side surface of the outer frame 2. After the drive motor 3-4 is started, it drives the outer frame 2 to move smoothly along the guide rod 3-1 through the meshing transmission of the gear and rack, providing continuous moving power for the cleaning components.

[0027] The ultrasonic generator 3-3 on the two sides of the outer frame is connected to the ultrasonic head 3-8 at the bottom of the movable frame 3-7 via wires. The generator can convert electrical energy into high-frequency vibration energy and transmit it to the ultrasonic head 3-8. When the ultrasonic head 3-8 passes over the surface of the water pipe or nozzle, it can peel off the attached dirt and impurities through high-frequency vibration.

[0028] A pair of connecting frames 3-6 are symmetrically distributed on the two side surfaces of the outer frame. The movable frame 3-7 is vertically and movablely mounted inside the connecting frame 3-6 and can slide up and down along the connecting frame 3-6. A pair of springs 3-9 mounted on the movable frame 3-7 are located on the upper and lower sides of the connecting frame 3-6 respectively. The elastic force of the springs 3-9 can push the movable frame 3-7 downward, so that the ultrasonic head 3-8 is always tightly held at a certain distance on the surface of the water pipe or nozzle, which is suitable for cleaning scenarios with different pipe diameters or surface undulations.

[0029] The support slide rods 3-10 at both ends of the bottom of the connecting frame 3-6 extend vertically downwards, with their lower ends higher than the ultrasonic head 3-8. When the outer frame 2 moves or the cleaning component comes into contact with the protruding structure, the support slide rods 3-10 can first come into contact with the surface of the water pipe to prevent the ultrasonic head 3-8 from directly colliding with hard objects and causing damage. At the same time, it helps the movable frame 3-7 to maintain a vertical state.

[0030] During operation, in outdoor settings, the drive motor 3-4 moves the outer frame 2 along the guide rod 3-1. The ultrasonic generator 3-3 is activated, and the ultrasonic head 3-8, under the action of the spring 3-9, adheres to the water pipe or nozzle, cleaning surface and crevices of dirt through high-frequency vibration. The support slide rod 3-10 moves synchronously with the outer frame 2, protecting the ultrasonic head 3-8 and maintaining cleaning stability. The gear and rack transmission ensures uniform movement speed, the elastic contact of the spring 3-9 improves cleaning coverage, and ultrasonic cleaning can penetrate deep into crevices to remove stubborn dirt. All components work together to achieve efficient and non-destructive cleaning of outdoor light pole nozzles. like Figures 1-3As shown in the figure, the fixed connection assembly 4 in this embodiment includes a sleeve 4-1, which is fixed to one end of the side frame 1. The sleeve 4-1 has a semi-circular structure and is fixedly connected to each other by bolts. A pair of splicing frames 4-2 are provided at the other end of the side frame 1. Each splicing frame 4-2 has a protrusion 4-3 on its upper surface. A tightening frame 4-4 is fitted between the pair of opposing protrusions 4-3. The tightening frame 4-4 is fixedly connected to the protrusions 4-3 by bolts. Both sides of the tightening frame 4-4 are inclined structures. An elastic frame 4-5 is provided on the inner side of one end of the side frame 1. The elastic frame 4-5 is positioned opposite to the splicing frame 4-2.

[0031] In some examples, in order to achieve a secure fit between the device and the lamp post water pipe, provide a reliable support base for the mobile cleaning component 3, and adapt to lamp post water pipes of different diameters, a fixed connection component 4 is designed. The sleeve 4-1 fixed at one end of the side frame 1 of this component has a semi-circular structure, and its inner wall curvature matches the shape of the lamp post water pipe. After the semi-circular sleeves 4-1 of the two side frames 1 are spliced ​​together, a complete ring structure can be formed to wrap around the outside of the water pipe. The sleeves 4-1 are connected by bolts. When the bolts are tightened, the splicing gap between the two sleeves 4-1 can be reduced, so that the inner wall of the sleeve 4-1 fits tightly against the surface of the water pipe, thus initially achieving the fixation of the device and the water pipe. A pair of splicing frames 4-2 at the other end of the side frame 1 are symmetrically distributed. The protrusions 4-3 on the upper surface of the splicing frame 4-2 provide mounting points for the clamping frame 4-4. After the pair of opposing protrusions 4-3 are aligned, the clamping frame 4-4 is fitted onto the protrusions 4-3 through the concave part in the middle. The clamping frame 4-4 and the protrusions 4-3 are fixedly connected by bolts. When the bolts are tightened, the clamping frame 4-4 can generate a pulling force towards the middle on both sides of the splicing frame 4-2, further reducing the gap between the side frames 1 and enhancing the clamping force between the device and the water pipe.

[0032] The inclined structure on both sides of the inner side of the clamping bracket 4-4 can gradually fit the surface of the protrusion 4-3 during the bolt tightening process, disperse the clamping force, and prevent the protrusion 4-3 from being damaged due to excessive local stress. The elastic frame 4-5 on the inner side of one end of the side frame 1 is made of elastic material (such as spring 3-9 steel, rubber). Its position corresponds to the splicing frame 4-2. When the side frame 1 is tightened onto the water pipe through the sleeve 4-1 and the clamping frame 4-4, the elastic frame 4-5 will undergo elastic deformation due to the clamping force of the side frame 1, and press tightly against the surface of the water pipe, filling the tiny gap between the sleeve 4-1 and the water pipe. At the same time, the elastic reaction force enhances the friction between the device and the water pipe, preventing the device from sliding due to vibration or gravity during the cleaning process.

[0033] During operation, first, the semi-circular sleeves 4-1 of both side frames 1 are aligned with the water pipe and secured with bolts. Then, the tightening frame 4-4 is fitted onto the protrusion 4-3 and the bolts are tightened. Pulling the splicing frame 4-2 reduces the distance between the side frames 1. Simultaneously, the elastic frame 4-5 deforms and presses against the water pipe, completing the secure tightening. The multi-part fixing structure and elastic compensation design ensure that the device remains stable in complex outdoor environments, guaranteeing the normal operation of the mobile cleaning component 3.

[0034] For example, such as Figure 1 As shown, a photovoltaic panel 5 is installed on the top of the outer frame 2, and the photovoltaic panel 5 is fixed at an inclined angle.

[0035] In some examples, the photovoltaic panels 5 on top of the outer frame 2 are fixed at an inclined angle, which can efficiently receive solar energy and convert it into electrical energy. The inclined design can adapt to the angle of sunlight at different times, improve the utilization rate of light energy, and the generated electricity can supply components such as ultrasonic generator 3-3 and drive motor 3-4, reducing dependence on external power sources. This is especially suitable for outdoor or power-inconvenient scenarios, enhancing the device's endurance and usage flexibility.

[0036] For example, such as Figure 2 As shown, the outer frame 2 has an overall L-shaped structure, and the outer frame 2 covers the drive motor 3-4 at the bottom.

[0037] In some examples, the outer frame 2 has an overall L-shaped structure, with the horizontal portion covering the drive motor 3-4 at the bottom. This structure can block dust, moisture, and other debris from the drive motor 3-4, reducing the corrosive effects of the external environment on the motor and extending its service life. At the same time, the L-shaped design makes the outer frame 2 compact, accommodating the installation space of each component of the mobile cleaning assembly 3, ensuring that the meshing of the drive gear 3-5 and the internal rack 3-2 is not affected by obstruction, and guaranteeing stable transmission.

[0038] For example, such as Figure 1 As shown, the surface of the supporting protrusion 4-2 and the inner surface of the sleeve 4-1 are both frosted anti-slip structural surfaces.

[0039] In some examples, the anti-slip structure between the surface of the supporting protrusion 4-2 and the inner surface of the sleeve 4-1 has a large frictional force, which can enhance the fit and tightness with the pipeline. The anti-slip structure can increase the frictional force between the contact surface and the pipeline, preventing the side frame 1 from slipping due to vibration during cleaning. Combined with bolt fixing, it further improves the overall stability, ensures the relative position of the ultrasonic head 3-7 and the nozzle is stable, and guarantees a uniform cleaning effect.

[0040] For example, such as Figure 1 As shown, a stabilizing pulley 6 is provided at one end of the connecting frame 3-6, and the stabilizing pulley 6 is supported on the inner surface of the side frame 1 on the other side.

[0041] In some examples, a stabilizing pulley 6 at one end of the connecting frame 3-6 supports the inner surface of the other side frame 1, forming a two-way support structure that significantly improves the stability of the outer frame 2 during movement. The outer frame 2, which originally only slides along one guide rod 3-1, is prone to tilting due to unilateral force. The rolling contact between the stabilizing pulley 6 and the inner surface of the other side frame 1 balances the forces on both sides of the outer frame 2, limiting its lateral displacement and overturning tendency. Simultaneously, the pulley's low rolling friction resistance does not hinder the smooth movement of the outer frame 2 along the guide rod 3-1, ensuring uniform speed when the drive motor 3-4 moves the outer frame 2 horizontally, further improving the uniformity and reliability of cleaning, especially suitable for outdoor light pole nozzles with long cleaning paths.

[0042] In practical use: The pair of side frames 1 of the device are attached to the water pipe of the lamp post. The semi-circular sleeves 4-1 are spliced ​​together and fixed with bolts. The tightening frame 4-4 is fitted onto the protrusion 4-3 of the splicing frame 4-2 and the bolts are tightened. Pulling the side frames 1 reduces the gap, and the elastic frame 4-5 deforms to press against the water pipe for stable fixation. The moving cleaning component 3 is activated. The drive motor 3-4 drives the drive gear 3-5 to mesh with the internal rack 3-2 of the guide rod 3-1, causing the outer frame 2 to move smoothly along the guide rod 3-1. The photovoltaic panel 5 powers the component. The ultrasonic generator 3-3 is activated. The movable frame 3-7, under the action of the spring 3-9, pushes the ultrasonic head 3-8 close to the nozzle and pipe, using high-frequency vibration to remove dirt. The support slide 3-10 prevents the ultrasonic head 3-8 from being damaged by collision, and the stabilizing pulley 6 helps the outer frame 2 maintain balance. After cleaning, the bolts are loosened and the device is removed. The entire process requires no manual climbing of the lamp post, achieving automated cleaning.
