Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically an ultraviolet sterilization device with adjustable contact depth. Background Technology

[0002] With the increasing emphasis on public health and safety in modern society, ultraviolet (UV) sterilization technology, due to its high efficiency and environmental friendliness, is widely used in water treatment, air disinfection, and surface disinfection. Ultraviolet (UV) radiation is electromagnetic radiation with wavelengths between 10 nm and 400 nm. Among them, UVC ultraviolet radiation with wavelengths between 200 nm and 280 nm has a strong bactericidal effect, effectively destroying the DNA or RNA of bacteria, viruses, and other microorganisms, thereby achieving inactivation.

[0003] In water treatment and disinfection, ultraviolet (UV) lamps installed in open channels are a common application, especially in wastewater and drinking water treatment. Traditional UV lamp sterilization devices are typically designed as fixed units, lacking adjustable contact distance or depth with the wastewater. This design limits their flexibility and sterilization effectiveness in different application scenarios. Furthermore, this design necessitates that the UV lamp completely fill the channel to ensure adequate irradiation and sterilization, resulting in higher costs.

The technical solution employs a lamp holder connection wire on one side of the ultraviolet lamp tube. A cleaning mechanism is provided on the surface of the mounting frame, consisting of a moving part, a connecting plate, and a cleaning ring. A quick-release mechanism, consisting of a disassembly component and a sleeve, is provided on the surfaces of the moving plate and the fixed plate. A wire-fixing mechanism is provided on one side of the fixed plate. This structure improves the installation stability of the ultraviolet lamp tube device; however, this design cannot adjust the contact distance or contact depth between the lamp and the wastewater to be treated.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] An adjustable-depth ultraviolet sterilization device, such as Figure 1 As shown, the sterilization device is installed on the open channel 1, including an ultraviolet lamp 7, a mounting bracket 6, and an adjusting device; the ultraviolet lamp 7 is connected to the mounting bracket 6, and the adjusting device is connected to the open channel 1; the open channel 1 is provided with a mounting groove 8, and the two sides of the mounting bracket 6 are slidably connected in the mounting groove 8; the adjusting device includes a worm gear 14, a worm 13, a gear set, and a rack; as shown... Figure 2 as well as Figure 3 As shown, the rack is fixed to both sides of the mounting frame 6, and the worm gear 14 and worm 13 are rotatably connected to and mesh with the open channel 1; the gear set is connected to the open channel 1; one side of the gear set meshes with the rack, and the other side is connected to the worm gear 14. The ultraviolet lamp 7 is used for sterilization and disinfection. The mounting groove 8 allows the mounting frame 6 to move up and down within the open channel 1. The up and down movement of the mounting frame 6 drives the up and down movement of the ultraviolet lamp 7.

[0033] Specifically, in use, the ultraviolet lamps 7 are evenly spaced inside the mounting frame 6, and the mounting frame 6, along with the ultraviolet lamps 7, is installed in the open channel 1. During installation, the two sides of the mounting frame 6 are simply inserted into the mounting slots 8. When it is necessary to adjust the contact depth between the ultraviolet lamps 7 and the sewage, the worm gear 13 is rotated. The worm gear 13 drives the worm wheel 14 to rotate, which in turn drives the gear set to rotate. The gear set then drives the rack to move, which in turn moves the mounting frame 6. By controlling the raising and lowering of the mounting frame 6, the ultraviolet lamps 7 are raised and lowered, thus adjusting the contact depth between the ultraviolet lamps 7 and the sewage.

[0034] In a preferred embodiment, such as Figure 2 As shown, a top beam 9 is detachably connected to the mounting bracket 6. Several lower mounting heads 5 are located at the bottom of the mounting bracket 6, and several upper mounting heads 4 are connected to the top beam 9. The two ends of the ultraviolet lamp tube 7 are connected to the upper mounting heads 4 and the lower mounting heads 5, respectively. The beam design facilitates the installation and replacement of the ultraviolet lamp tube 7. This design allows the top beam 9 to be removed and reinstalled, enabling the two ends of the ultraviolet lamp tube 7 to be easily connected to the upper mounting heads 4 and the lower mounting heads 5, thus achieving stable fixation of the ultraviolet lamp tube 7 on the mounting bracket 6.

[0035] In a preferred embodiment, such as Figure 4 As shown, the lower mounting head 5 includes a base 24, auxiliary clips, a tension spring 23, and a mounting sleeve 27. The base 24 is fixedly connected to the mounting bracket 6, the mounting sleeve 27 is connected to the base 24, and the ultraviolet lamp 7 is connected to the mounting sleeve 27. The auxiliary clips are located on both sides of the mounting sleeve 27 and are slidably connected to the base 24. The two ends of the tension spring 23 are connected to the auxiliary clips on both sides respectively. Specifically, in use, the auxiliary clips are separated, and the ultraviolet lamp 7 is inserted into the mounting sleeve 27. Releasing the auxiliary clips clamps the bottom of the ultraviolet lamp 7, thereby stabilizing the position of the ultraviolet lamp 7. This design improves the ease of installation of the ultraviolet lamp 7.

[0036] In a preferred embodiment, such as Figure 4 As shown, the auxiliary clamps include a first auxiliary clamp 28 and a second auxiliary clamp 21. A first toothed plate 26 is fixedly connected to the first auxiliary clamp 28, and a second toothed plate 22 is fixedly connected to the second auxiliary clamp 21. The first toothed plate 26 and the second toothed plate 22 are symmetrically arranged. A control gear 25 is rotatably connected to the base 24, and the two sides of the control gear 25 mesh with the first toothed plate 26 and the second toothed plate 22, respectively. Specifically, in use, rotating the control gear 25 causes the first toothed plate 26 and the second toothed plate 22 on both sides to move. Since the first toothed plate 26 and the second toothed plate 22 are symmetrically arranged on both sides of the control gear 25, their movement directions are opposite. This design facilitates the movement of the first auxiliary clamp 28 and the second auxiliary clamp 21 to both sides, which facilitates the installation of the ultraviolet lamp tube 7. Further optimized, a rotating head is connected to the control gear 25. The rotating head is used to facilitate the rotation of the control gear 25.

[0037] In a preferred embodiment, such as Figure 2As shown, a fixing screw 10 is provided between the top beam 9 and the mounting bracket 6, and the top beam 9 and the mounting bracket 6 are detachably connected by the fixing screw 10. Specifically, the fixing screw 10 passes through the connection part between the top beam 9 and the mounting bracket 6, which can firmly fix the top beam 9 to the mounting bracket 6. At the same time, by tightening or loosening the fixing screw 10, the user can easily and quickly remove the top beam 9 when needed.

[0038] In a preferred embodiment, such as Figure 2 as well as Figure 3 As shown, the mounting frame 6 has limit plates 20 on both sides, and limit posts 11 are fixedly connected in the mounting groove 8. The limit plates 20 are slidably connected in the mounting groove 8, and the limit plates 20 are slidably connected to the limit posts 11. These limit plates 20 are slidably connected in the mounting groove 8 and slidably connected to the limit posts 11 fixed in the mounting groove 8. The limit posts 11 are used to ensure the stability of the mounting frame 6 during movement. This design ensures that the mounting frame 6 will not have excessive displacement when adjusting its position, thereby improving the safety and reliability of the structure.

[0039] In a preferred embodiment, such as Figure 1 As shown, an installation box 3 is fixedly connected to the outside of the open channel 1. The worm gear 14, worm 13, and gear set are all installed inside the installation box 3. The gear set includes a first gear 15, a second gear 16, a first adjusting gear 12, and a second adjusting gear 19. The worm gear 14 and worm 13 are rotatably connected inside the installation box 3 and mesh with each other. The first gear 15 is fixedly connected to the worm gear 14, the second gear 16 meshes with the first gear 15, the first adjusting gear 12 is fixedly connected to the first gear 15, and the second adjusting gear 19 is fixedly connected to the second gear 16. The rack includes a first rack 17 and a second rack 18. The first rack 17 and the second rack 18 are respectively fixedly connected to the installation frame 6 and symmetrically arranged. The first adjusting gear 12 meshes with the first rack 17, and the second adjusting gear 19 meshes with the second rack 18.

[0040] Specifically, during use, rotating the worm gear 13 drives the worm wheel 14 to rotate, which in turn drives the first gear 15 to rotate. The first gear 15 then drives the first adjusting gear 12 and the second gear 16 to rotate, and the second gear 16 drives the second adjusting gear 19 to rotate. The first gear 15 and the first adjusting gear 12 rotate in the same direction. The second gear 16 rotates in the opposite direction to the first gear 15, and the second adjusting gear 19 rotates in the same direction as the second gear 16. Since the first rack 17 and the second rack 18 are symmetrically arranged, this method allows the first and second adjusting gears 19 to simultaneously move the mounting bracket 6 from both sides, improving the stability of the mounting bracket 6's movement.

[0041] In a preferred embodiment, such as Figure 2 as well as Figure 3As shown, one side of the worm gear 13 extends out of the mounting box 3 and is connected to a rotating handle 2. The rotating handle 2 has a Z-shaped structure, which allows for easy rotation of the worm gear 13.

[0042] In a preferred embodiment, limiting plates 20 are provided on both sides of the mounting frame 6, and limiting posts 11 are fixedly connected in the mounting groove 8. The limiting plates 20 are slidably connected in the mounting groove 8, and the limiting plates 20 and the limiting posts 11 are slidably connected. The top and bottom of one side of the mounting frame 6 are both fixedly connected to the limiting plates 20, and both ends of the first rack 17 and the second rack 18 are both fixedly connected to the limiting plates 20. That is to say, the first rack 17, the second rack 18 and the limiting plates 20 are integrated. This design can improve the overall strength of the mounting frame 6 and facilitate the movement of the mounting frame 6 by the first adjusting gear 12 and the second adjusting gear 19.
