Description

Technical Field

[0001] The utility model belongs to the field of water treatment, in particular to an ultraviolet drinking water treatment device. Background Art

[0002] Compared to traditional chemical disinfection methods, UV disinfection offers advantages such as no blind spots, excellent light coverage, low energy consumption, flexible and convenient equipment installation and disassembly, and no secondary pollution. Furthermore, this technology is highly effective against all microorganisms, including Cryptosporidium parvum, which is highly immune to chlorine. Therefore, UV disinfection is widely used in drinking water treatment, aquaculture, and swimming pool water treatment.

[0003] like Figure 4 The figure shows a UV sterilization structure installed in a water tank. Multiple UV lamps are mounted in the tank using a mounting bracket. As water flows through, the UV lamps disinfect and sterilize the water. However, as UV lamps are exposed to the water tank for a long time, impurities will accumulate on their surface. Excessive accumulation of these impurities can obstruct the UV lamps. Utility Model Content

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0019] The ultraviolet drinking water treatment device provided in this embodiment is as follows: Figure 1 and Figure 2 As shown, it includes main components and improved components, wherein:

[0020] The main component includes two groove walls 1, forming a water groove in the middle, in which an ultraviolet disinfection structure consisting of a mounting frame 2 and multiple ultraviolet lamps 3 is placed; in addition, the top ends of the two groove walls 1 are connected to a U-shaped bracket 4 with an opening facing downward, and the height of this bracket 4 is much greater than the height of the ultraviolet disinfection structure.

[0021] The improved structure includes a vertical rod 5 connected to the top of the bracket 4, a sleeve 6 is inserted at the bottom of the vertical rod 5, and the bottom end of the sleeve 6 is fixed to the top of the mounting frame 2; at the same time, a driving mechanism 7 for driving the sleeve 6 to extend and retract on the vertical rod 5 is provided on the bracket 4. Figure 2 As shown, the driving mechanism 7 includes an external thread provided on the outer peripheral side of the vertical rod 5, so that its structure forms a screw, and the top end of the screw is connected to the bracket 4 through the bearing. Specifically, a connecting hole is provided at the top end of the bracket 4 at the position corresponding to the bearing, and the inner wall of the connecting hole is fixedly connected to the outer ring of the bearing, and the inner ring of the bearing is interference-fitted with the screw and then penetrates; at the same time, an internal thread is provided on the inner wall of the sleeve 6 to match the external thread, so that it can be screwed with the screw thread; In addition, on the one hand, a rotating mechanism 701 for driving the screw to rotate is provided on the bracket 4, as shown Figure 3 As shown, the rotating mechanism 701 includes a servo motor 70101 mounted on the top of the bracket 4, and the output shaft of the servo motor 70101 and the outer peripheral side of the screw are fixedly sleeved with mutually meshing gears 70102; on the other hand, the sleeve 6 can only be extended and retracted by limiting the rotation of the sleeve 6 when the screw rotates, so a limiting mechanism 702 for limiting the rotation of the mounting frame 2 is provided between the bracket 4 and the mounting frame 2, as shown in FIG. Figure 3 As shown, the limiting mechanism 702 includes two round rods 70201 fixed to the top of the mounting frame 2, symmetrical about the sleeve 6. The round rods 70201 movably penetrate the top of the bracket 4. Thus, driven by the servo motor 70101, the two gears 70102 can synchronously drive the screw to rotate, thereby causing the sleeve 6, which is restricted from rotation, to expand and contract in the longitudinal direction, thereby driving the ultraviolet disinfection structure to rise and fall. In this way, the ultraviolet lamp 3 can be removed from the water tank to facilitate cleaning and removal of impurities.

[0022] After the UV disinfection structure is taken out of the water tank, in order to facilitate the cleaning of the entire UV disinfection structure, it is best to separate it from the sleeve 6 and the round rod 70201. Therefore, a longitudinal short stud is connected to the bottom end of the round rod 70201 and the sleeve 6; at the same time, a screw hole that is compatible with the short stud is opened at the top of the mounting frame 2, so that it is threadedly engaged with the round rod 70201 and the sleeve 6.

[0023] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0024] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
