[0002] Ultraviolet disinfection technology is widely used in the field of water treatment. Common ultraviolet water treatment equipment includes a cavity and several groups of ultraviolet-transmissive quartz glass sleeves built into the cavity and ultraviolet lamps installed in the sleeves. In actual use, since the liquid entering the cavity generally contains suspended matter and calcium and magnesium ions, the heat generated by the ultraviolet lamp during operation will cause suspended matter and scaling to adhere to the surface of the sleeve, affecting the light transmittance of the sleeve.

[0003] Generally, a mechanical device installed on the sleeve is required to reciprocate and automatically clean the sleeve. There are many cleaning mechanisms at present, but they all have some problems. For example, in the harsh environment of sewage, due to the presence of a large amount of organic matter, suspended matter and calcium and magnesium ions in the water, once scale is formed on the lamp tube, such scale will hinder the cleaning part sleeved on the lamp tube from scraping it during cleaning, which can easily cause some deformation of the structure supporting the cleaning part in the cleaning mechanism, and then the moving trajectory of the cleaning part cannot ensure coaxiality with the lamp tube, which will increase the moving resistance of the cleaning part on the lamp tube, and even get stuck, and cause damage to the lamp tube.

[0027] See also Figure 1 to Figure 2As shown, in order to ensure that the cleaning member 3 has a larger adjustment space to remain coaxial with the lamp tube, avoid movement obstruction and jamming problems, and cause damage to the lamp tube, the utility model provides a lamp tube cleaning mechanism 8, which includes: a main substrate 1, a fixed cover 2, and a cleaning member 3, wherein a plurality of main supports 13 are provided on the main substrate 1 at positions corresponding to the lamp tube arrangement positions, a linkage seat 11 is provided at the center of the main substrate 1, a first opening is provided on the main support 13, an annular recess is provided on the back of the fixed cover 2, a second opening is provided in the middle of the recess, the fixed cover 2 is connected to the main support 13 of the main substrate 1, so that the first opening is coaxially arranged with the second opening, and a floating groove 12 is defined between the recess and the main support 13, the cleaning member 3 is annular, and is accommodated in the floating groove 12, the diameter of the cleaning member 3 is smaller than the diameter of the floating groove 12, so as to define a radial floating gap between the floating groove 12 and the cleaning member 3, for example, in a preferred example, the single-sided floating gap between the cleaning member 3 and the floating groove 12 can be set to 2-5mm.

[0028] Specifically, Figure 1 As shown, in this example, the main substrate 1 includes: a linkage seat 11, a main support 13, and a main bracket 14. The main support 13 is arranged in a circular diffusion shape around the first end of the linkage seat 11. The number of outer circles of the circular diffusion corresponds to the number and shape of the lamp tubes. The main bracket 14 forms a supporting connection between each of the main supports 13 and between the main support 13 and the first end of the linkage seat 11.

[0029] Among them Figure 1 As shown, in this example, the main bracket 14 is shaped like a tree branch, and the layout positions of each main support 13 are fixed in an outward radiating fork manner. This can make the main substrate 1 lightweight on the one hand, and at the same time allow more gaps to exist between the main brackets 14, which is beneficial to reduce water resistance during movement in a water treatment environment.

[0030] Further, such as Figure 2 As shown, the cleaning member 3 is ring-shaped. In a preferred example, in order to improve the ability to scrape dirt, a plurality of toothed rings 31 can be optionally provided on the inner ring surface of the cleaning member 3. Through the design of the toothed rings 31, the same part of the lamp tube can be scraped multiple times during one pass, thereby improving the dirt removal effect.

[0031] Furthermore, considering that sometimes there may be some stubborn dirt on the lamp tube, which may not be scraped off in one go, this will hinder the movement of the cleaning part 3 and jam the entire cleaning mechanism. For this reason, in a preferred example, the toothed ring 31 may be made of an elastic material, such as rubber, silicone, resin, and other materials with a certain degree of flexibility and elasticity. In this way, when encountering stubborn dirt, the toothed ring 31 can be allowed to sweep over it without getting stuck there, thereby removing dirt through multiple scrapings to ensure the reliability of the mechanism.

[0032] With this arrangement, when the lamp tube passes through the first and second openings on the fixed cover 2 and the main support 13 of the main substrate 1, and the cleaning component 3 is sleeved on the outer wall of the lamp tube, the main substrate 1 is moved in a horizontal position of the lamp tube, which can drive the cleaning component 3 to scrape off the dirt on the outer wall of the lamp tube. At this time, due to the existence of the floating gap in the floating groove 12, even if the lamp tube may not be completely horizontal with the moving direction of the main substrate 1, the cleaning component 3 can be allowed to float or descend with the help of the floating gap, so as to adjust its position to keep it coaxial with the lamp tube, avoid blocking the movement of the main substrate 1 and causing deformation of the main substrate 1. In addition, with this arrangement, the requirements for horizontal layout of the lamp tube and the manufacturing and assembly accuracy requirements of the main substrate 1 are substantially reduced, thereby improving the fault tolerance of the structure to maintain long-term and stable operation of the mechanism.

[0033] On the other hand, in order to improve the efficiency of lamp cleaning, such as Figure 3 to Figure 4 As shown, in a preferred example, the lamp cleaning mechanism 8 further includes: a secondary substrate 1', the secondary substrate 1' and the main substrate 1 are arranged in a back-to-back mirror image, wherein the secondary substrate 1' is provided with a secondary support 13', and the secondary support 13' is provided with a third opening, the fixed cover 2 is also connected to the secondary support 13' of the secondary substrate 1', and a floating groove 12 is defined between the concave platform and the secondary support 13' to accommodate the cleaning member 3, and the diameter of the cleaning member 3 is smaller than the diameter of the floating groove 12, so as to define a radial floating gap between the floating groove 12 and the cleaning member 3, for example, in a preferred example, the single-side floating gap between the cleaning member 3 and the floating groove 12 can be set to 2-5mm. The central part of the secondary substrate 1' is connected to the linkage seat 11 of the main substrate 1, so that the first, second and third openings are coaxially arranged.

[0034] Specifically, Figure 3 As shown, the secondary substrate 1' comprises: a secondary support 13' and a secondary bracket 14', wherein the secondary support 13' is arranged in a circular diffusion shape around the second end of the linkage seat 11, and the secondary supports 13' and the secondary supports 13' and the second end of the linkage seat 11 are supported and connected by the secondary bracket 14'. Since the structure of the secondary substrate 1' is similar to that of the main substrate 1 and the functions are similar, they will not be described here.

[0035] Further, such as Figure 4 As shown, in order to enhance the structural stability of the main / auxiliary substrates 1, 1', the lamp tube cleaning mechanism 8 further includes: a connecting rod member 4, wherein each of the main / auxiliary supports 13, 13' is provided with a main / auxiliary connecting rod seat 15, 15', and the main / auxiliary connecting rod seats 15, 15' are connected via the connecting rod member 4. This arrangement forms a support at the position where each cleaning component 3 is sleeved with the lamp tube, thereby preventing the main / auxiliary substrates 1, 1' from being deformed due to resistance, thereby improving the structural reliability of the cleaning mechanism.

[0036] On the other hand, Figure 5As shown, corresponding to the lamp tube cleaning mechanism 8 of the above example, the utility model also provides an ultraviolet water treatment device, which includes: a screw device 5, an ultraviolet lamp tube 6, a water tank 7, and a lamp tube cleaning mechanism 8, wherein the lamp tube cleaning mechanism 8 is any structure of the above example, wherein the ultraviolet lamp tube 6 is connected to the water tank 7 so that the light emitting side of the ultraviolet lamp tube 6 is placed in the water tank 7, the cleaning part 3 of the lamp tube cleaning mechanism 8 is sleeved on the ultraviolet lamp tube 6, and the moving end of the screw device 5 is connected to the linkage seat 11 of the lamp tube cleaning mechanism 8.

[0037] When the ultraviolet water treatment equipment is in operation, the lamp tube cleaning mechanism 8 is driven by the screw device 5, which drives the cleaning component 3 sleeved on the lamp tube to reciprocate and scrape the dirt on the ultraviolet lamp tube 6, thereby achieving the effect of removing dirt on the lamp tube. It is worth mentioning that since the lamp tube cleaning mechanism 8 in the above example is specially designed with a suspended structure of the cleaning component 3, its overall structural fault tolerance advantage is more reflected in the scenario of simultaneous cleaning of a large number of lamp tubes, and each cleaning component 3 can adjust its position relative to the main / auxiliary substrate 1, 1' to keep it coaxially arranged with each lamp tube.

[0038] In summary, through the lamp tube cleaning mechanism 8 provided by the utility model and the ultraviolet water treatment equipment using the same, a floating structure is cleverly designed, so that the cleaning part 3 can float on the substrate, thereby ensuring that the cleaning part 3 has a larger adjustment space to remain coaxial with the lamp tube when moving, thereby reducing the design adaptation accuracy requirements between the substrate and the lamp tube, making it difficult for the cleaning part 3 to be obstructed or stuck when moving, thereby ensuring that the substrate is not easily deformed, improving the fault tolerance of the overall structure, and avoiding damage to the lamp tube.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the contents of this specification.
