The inner threaded block is driven by the two-way threaded rod to move on the surface of the two-way threaded rod, thereby driving the extrusion block to extrude the inner side surface of the water channel, so that the fixed mounting block is achieved. The two two-way lead screws are driven by the cooperation of the worm and the worm wheel to rotate, and the moving block is driven by the two-way lead screws to move. The device can be adjusted according to lamp holders with different lengths and sizes, and is convenient to install. By rotating the handle, the sliding frame is pulled to extrude the spring, so that the rotating plates are conveniently matched with each other through the grooves on the outer surfaces of the rotating plates. When the rotating plates are horizontal, the rotating handle is loosened. Under the action of the spring, the sliding frame is slid to the position where the two rotating plates match with each other, so that the rotating plates are locked. The gap above the lamp holder is shielded by the rotating plates, so that the ultraviolet light is prevented from leaking from above the lamp holder, and the safety is improved.

Description

Technical Field

[0001] This utility model relates to the field of ultraviolet disinfection technology, and in particular to an ultraviolet disinfection device. Background Technology

[0002] Ultraviolet (UV) disinfection is a disinfection technology widely used in the field of water treatment. It uses UV light of a specific wavelength to destroy the DNA or RNA of microorganisms, thereby killing or inactivating microorganisms such as bacteria, viruses, fungi, and parasites.

[0003] Existing ultraviolet disinfection technologies for wastewater treatment are mainly divided into two categories: open channel ultraviolet disinfection devices and pipeline ultraviolet disinfection devices. Taking the open channel ultraviolet disinfection device as an example, several ultraviolet lamp holders are placed in a water channel, and the water flowing inside the water channel passes through the position of the ultraviolet lamp holders, thereby achieving ultraviolet disinfection of wastewater.

[0004] Existing open-channel ultraviolet disinfection devices require the fabrication of external fixing frames based on the dimensions of ultraviolet lamp holders of different specifications during installation. They cannot be adjusted for ultraviolet lamp holders of different sizes, making the installation process cumbersome and inconvenient to use. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This is the first embodiment of the present utility model. This embodiment provides an ultraviolet sterilizer, including a water channel 1, a lamp holder 4 is provided inside the water channel 1, and an installation component 3 is provided between the water channel 1 and the lamp holder 4.

[0031] The mounting assembly 3 includes two mounting blocks 301 fixedly mounted on the outer surface of the water channel 1. Two bidirectional lead screws 303 are movably connected between the two mounting blocks 301. Two moving blocks 302 are meshed with the outer surfaces of the bidirectional lead screws 303. A drive shaft 304 is movably connected to the interior of each of the two mounting blocks 301 through bearings. Two worm gears 307 are fixedly mounted on the outer surface of the drive shaft 304. Worm wheels 308 are fixedly mounted at both ends of the bidirectional lead screws 303. The worm gears 307 and worm wheels 308 are meshed with each other.

[0032] Specifically, the upper surface of the movable block 302 is provided with several slots that cooperate with the lamp holder 4, so that the lamp holder 4 can be installed through the slots, making it convenient for the lamp holder 4 to be inserted into the slots.

[0033] Specifically, both mounting blocks 301 are internally connected to bidirectional threaded rods 306 via bearings. An internal threaded block 309 is engaged with the outer surface of the bidirectional threaded rod 306. A pressing block 305 is fixedly connected to the lower surface of the internal threaded block 309. The outer surface of the pressing block 305 has an inclined surface. A limiting groove is provided on the lower surface of the mounting block 301 to cooperate with the pressing block 305. The bidirectional threaded rod 306 drives the pressing block 305 to press against the inner side of the water channel 1, thus facilitating the fixing of the mounting block 301. The inclined surface of the outer surface of the pressing block 305 reduces the impact of the flowing water in the water channel 1 on the pressing block 305. The limiting groove facilitates the movement of the pressing block 305. Furthermore, the cooperation between the pressing block 305 and the limiting groove limits the internal threaded block 309, preventing it from rotating with the bidirectional threaded rod 306.

[0034] Specifically, driven bevel gears 310 are fixedly connected to both ends of the drive shaft 304 and the bidirectional threaded rod 306. A rotating block 312 is provided on the upper surface of the mounting block 301. A drive bevel gear 311 is fixedly connected to the lower surface of the rotating block 312 through a rotating shaft passing through the upper surface of the mounting block 301. The drive bevel gear 311 meshes with the driven bevel gear 310. Through the cooperation between the drive bevel gear 311 and the driven bevel gear 310, the user only needs to rotate the upper rotating block 312 to rotate the drive shaft 304 and the bidirectional threaded rod 306. It is not necessary to directly rotate the drive shaft 304 and the bidirectional threaded rod 306 on the side of the water channel 1 close to the ground, which is convenient to use.

[0035] Furthermore, when the bidirectional threaded rod 306 rotates, it drives the internal threaded block 309 to move on the surface of the bidirectional threaded rod 306, thereby driving the extrusion block 305 to extrude the inner side of the water channel 1, thus fixing the mounting block 301. When the transmission shaft 304 rotates, it drives the two bidirectional screws 303 to rotate through the cooperation of the worm gear 307 and the worm wheel 308. When the bidirectional screws 303 rotate, they drive the moving block 302 to move. When the moving block 302 moves to the position that matches the lamp holder 4, it can stop rotating. Then, the lamp holder 4 is inserted into the slot on the upper surface of the moving block 302, thus completing the installation of the lamp holder 4. It can be adjusted according to different lengths of the lamp holder 4, making installation convenient.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, and the upper surfaces of the two mounting blocks 301 are provided with shielding components 2.

[0038] The shielding assembly 2 includes a rotating plate 201 hinged to the upper surface of the mounting block 301 via a hinge seat. A fixed frame 202 is fixedly connected to the outer surface of the rotating plate 201 on the side closer to the hinge seat, and a sliding frame 204 is fixedly connected to the outer surface of the rotating plate 201 on the side away from the hinge seat. Two springs 203 are fixedly connected between the sliding frame 204 and the fixed frame 202.

[0039] Specifically, the outer surfaces of the two rotating plates 201 are provided with mutually cooperating grooves. The cooperation of the grooves allows the two rotating plates 201 to rotate to a horizontal position, and facilitates the sliding frame 204 to lock the cooperating position.

[0040] Specifically, the upper surface of the sliding frame 204 is hinged to a rotating handle 205 via a hinge seat. The hinged arrangement of the rotating handle 205 allows the user to adjust the angle by rotating the handle 205 when pulling the rotating plate 201, thereby keeping the sliding frame 204 compressing the spring 203 and preventing the sliding frame 204 from obstructing the cooperation of the two rotating plates 201.

[0041] Furthermore, by rotating the handle 205, the sliding frame 204 is pulled to compress the spring 203, thus facilitating the interaction of the rotating plates 201 through the grooves on their outer surfaces. Once the rotating plates 201 are horizontal, the handle 205 is released, and under the action of the spring 203, the sliding frame 204 slides to the position where the two rotating plates 201 interact, thereby locking the rotating plates 201. The rotating plates 201 shield the gap above the lamp holder 4, thus preventing ultraviolet rays from escaping from above the lamp holder 4 and improving safety. For the exposed parts on the sides, the ultraviolet rays are mainly blocked by the water flowing in the water channel 1. As for the parts that cannot be blocked, based on the existing installation structure of the water channel 1, the user standing above the water channel 1 is less affected by the ultraviolet rays exposed on the sides, so this is not considered.

[0042] Working Principle: When installing the UV sterilizer, the mounting block 301 is placed on the water channel 1. Then, using a hex wrench, the rotating block 312 is rotated sequentially. This, through the engagement of the drive bevel gear 311 and the driven bevel gear 310, drives the drive shaft 304 and the double-threaded rod 306 to rotate. When the double-threaded rod 306 rotates, it causes the internal threaded block 309 to move on the surface of the double-threaded rod 306, thereby causing the pressing block 305 to press against the inner side of the water channel 1, thus fixing the mounting block 301. When the drive shaft 304 rotates, through the engagement of the worm gear 307 and the worm wheel 308, it drives the two double-threaded screws 303 to rotate. When the double-threaded screws 303 rotate, they drive the moving block 302 to move. When the moving block 302 moves to the position that engages with the lamp holder 4, the rotation stops. Next, insert the lamp holder 4 into the slot on the upper surface of the moving block 302 to complete the installation of the lamp holder 4. It can be adjusted according to different lengths of the lamp holder 4 for easy installation. After installation, rotate and close the two rotating plates 201. When rotating the rotating plates 201, the sliding frame 204 is pulled by rotating the handle 205 to compress the spring 203, so that the rotating plates 201 can cooperate with each other through the grooves on the outer surface. After the rotating plates 201 are horizontal, release the rotating handle 205. Under the action of the spring 203, the sliding frame 204 slides to the position where the two rotating plates 201 cooperate, thereby locking the rotating plates 201. The rotating plates 201 block the gap above the lamp holder 4, thereby preventing ultraviolet rays from being exposed from above the lamp holder 4, improving safety, and finally completing the installation of the ultraviolet sterilizer.
