DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0043] It should be noted that, in the description of the present application, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0044] In addition, it should be understood that, for the convenience of description, the sizes of the various components shown in the drawings are not drawn in accordance with the actual proportional relationship, for example, the thickness or width of certain layers can be exaggerated relative to other layers.

[0045] ​​It should be noted that like reference numerals and characters refer to like items throughout the drawings and like materials function in like manner, so once an item is defined or described in one drawing, it is not necessary to discuss or describe it further in the description of the subsequent drawings.

[0046] To solve the technical problem that the existing ultraviolet reduction device in the background art is mainly suitable for the application scenario of water body sterilization and disinfection and is not suitable for the application scenario of water quality detection, the present application provides an ultraviolet reduction device applied to water quality detection of a to-be-tested water sample. The ultraviolet reduction device comprises a shell 1, a clamping assembly 3, a light-shielding cover 2, at least one reaction container 5, and at least one ultraviolet lamp tube 6. Specifically, each reaction container 5 has a storage cavity capable of being sealed, the storage cavity is used to store the to-be-tested water sample, and the reaction container 5 is capable of transmitting ultraviolet rays. The clamping assembly 3 is arranged on the shell 1 and is used to clamp each reaction container 5. The light-shielding cover 2 can be buckled on the shell 1. Each ultraviolet lamp tube 6 is arranged on the light-shielding cover 2, and after the light-shielding cover 2 is buckled on the shell 1, each ultraviolet lamp tube 6 is opposite to each reaction container 5.

[0047] It should be noted that in the embodiments of the present application, the shape and structure of the reaction container 5 are not limited. For example, the reaction container 5 can be a tubular, spherical or cup-shaped container, etc. In order to make the reaction container 5 have a storage cavity capable of being sealed, a sealing cover can be provided for the reaction container 5. If it is necessary to inject the to-be-tested water sample into the storage cavity, the sealing cover is opened; if it is necessary to seal the storage cavity, the sealing cover is closed. It should be noted that the sealing of the storage cavity by the cover is a mature technology, which will not be described here.

[0048] In the embodiments of the present application, the reaction container 5 can be of any suitable material as long as it can transmit ultraviolet rays, that is, when the reaction container 5 is used, ultraviolet rays can irradiate the to-be-tested water sample inside the reaction container 5. For example, the reaction container 5 can be of quartz material or organic glass material, etc.

[0049] In the embodiments of the present application, the ultraviolet lamp tube 6 can be any lamp tube capable of emitting ultraviolet rays. For example, the ultraviolet lamp tube 6 can be an ultraviolet mercury lamp or a vacuum ultraviolet mercury lamp, etc. It should be noted that compared with the ultraviolet mercury lamp, the vacuum ultraviolet mercury lamp can generate high-energy photons, so the vacuum ultraviolet mercury lamp can degrade pollutants more than the ultraviolet mercury lamp. In the present embodiment, each ultraviolet lamp tube 6 is opposite to each reaction container 5, which means that the ultraviolet rays emitted by the ultraviolet lamp tube 6 can irradiate the reaction container 5.

[0050] It should be noted that in the embodiments of the present application, the light-shielding cover 2 and the shell 1 can be a separate structure, and the light-shielding cover 2 is buckled on the shell 1 when in use. The light-shielding cover 2 and the shell 1 can also be hingedly connected as shown in Figure 2 It should be noted that in the embodiments of the present application, the light-shielding cover 2 and the shell 1 can be a separate structure, and the light-shielding cover 2 is buckled on the shell 1 when in use. The light-shielding cover 2 and the shell 1 can also be hingedly connected as shown in

[0051] In the embodiments of the present application, the clamping assembly 3 can be any assembly capable of clamping the reaction container 5 to stabilize the reaction container 5. For example, the clamping assembly 3 can be the clamping device disclosed in the patent documents with publication numbers CN206139244U or CN211537856U. In order to simplify the structure of the clamping assembly 3 and reduce the manufacturing cost of the clamping assembly 3, in an embodiment of the present application, the clamping assembly 3 includes a clamping plate 31 and two strip-shaped protrusions 32. As shown in the drawings, the two strip-shaped protrusions 32 are arranged in parallel on the first surface of the clamping plate 31, each strip-shaped protrusion 32 is threadedly connected with a plurality of threaded columns 33, and the axis of each threaded column 33 is parallel to the first direction. The first direction is perpendicular to the extension direction of the strip-shaped protrusion 32 and parallel to the first surface of the clamping plate 31, that is, the Y direction as shown in the drawings. In use, by adjusting the position of each threaded column 33, the reaction container 5 can be clamped. Figure 3 Figure 3

[0052] In the embodiments of the present application, the shape and structure of the clamping plate 31 are not limited, for example, the clamping plate 31 can be a circular plate or a square plate as shown in the drawings. Figure 3

[0053] In the embodiments of the present application, the shape and structure of the strip-shaped protrusion 32 are not limited, for example, the strip-shaped protrusion 32 can be a sheet-shaped strip structure, a columnar strip structure, or a strip structure as shown in the drawings. Figure 3

[0054] In the embodiments of the present application, a plurality of threaded columns 33 can be used to clamp one reaction container 5. In order to enable the clamping assembly 3 to clamp a plurality of reaction containers 5 at the same time, that is, to enable the ultraviolet reduction device to simultaneously perform ultraviolet reduction on the water samples to be tested in a plurality of reaction containers 5, in a specific embodiment of the present application, as shown in the drawings, the threaded columns 33 on the two strip-shaped protrusions 32 correspond one-to-one, and the axis of the corresponding threaded columns 33 coincides. In use, one end of the reaction container 5 is in contact with one of the corresponding two threaded columns 33, and the other end of the reaction container 5 is in contact with the other of the corresponding two threaded columns 33. Figure 3

[0055] In order to enable the corresponding two threaded columns 33 to stably clamp the reaction container 5, in the present embodiment, one end of each threaded column 33 towards the corresponding threaded column 33 is provided with a clamping block 34. The clamping block 34 is used to increase the contact area when clamping the reaction container 5. It is easy to understand that the larger the contact area between the threaded column 33 and the reaction container 5 when clamping, the more stable the clamping.​​​​​

[0056] In the embodiments of the present application, the shape and configuration of the clamping block 34 are not limited, as long as the clamping block 34 can increase the contact area when clamping the reaction container 5. For example, in the embodiments, the clamping block 34 can be in a sheet structure, or the clamping block 34 can be in a tubular structure. If the clamping block 34 is in a tubular structure, as shown in the drawings, the reaction container 5 can also be in a tubular structure, and in use, the axis of the clamping block 34 coincides with the axis of the corresponding threaded column 33, and the inner diameter of the clamping block 34 is greater than the outer diameter of the reaction container 5. Figure 2

[0057] It should be noted that in order to make the various components of the water sample to be tested in the reaction container 5 uniformly contact with the ultraviolet light, thereby reducing the time of ultraviolet reduction, in the embodiments of the present application, the ultraviolet reduction device further comprises an oscillation assembly 7, which is used to drive the clamping assembly 3 to perform linear reciprocating motion. It is easy to understand that if the clamping assembly 3 performs linear reciprocating motion, the reaction container 5 can also perform linear reciprocating motion. If the reaction container 5 performs linear reciprocating motion, the water sample to be tested in the reaction container 5 can produce linear oscillation, thereby making the various components of the water sample to be tested uniformly contact with the ultraviolet light.

[0058] In the embodiments of the present application, the oscillation assembly 7 can be any assembly that can drive the clamping assembly 3 to perform linear reciprocating motion. For example, the oscillation assembly 7 can be an electric push rod or a hydraulic push rod, etc. In the embodiments of the present application, in order to make the oscillation assembly 7 stably drive the clamping assembly 3 to perform linear reciprocating motion, the oscillation assembly 7 can include a first flat plate 701, a second flat plate 702, a first motor 703, a first driven wheel 705, a first eccentric shaft 707, and a limiting structure. Specifically, as shown in the drawings, in use, the clamping assembly 3 is arranged on the first flat plate 701 (not shown in the drawings), and the first flat plate 701 is provided with a strip-shaped slot 711. The first motor 703 is arranged on the second flat plate 702, and the output end of the first motor 703 is provided with a first driving wheel 704. The first driven wheel 705 is rotationally connected with the second flat plate 702, and the first driven wheel 705 and the first driving wheel 704 are drivingly connected through a first transmission belt 706. The first eccentric shaft 707 is arranged on the first driven wheel 705, and the eccentric column 708 of the first eccentric shaft 707 passes through the strip-shaped slot 711. The limiting structure is used to guide the first flat plate 701 to perform linear reciprocating motion. Figure 4 Figure 5

[0059] ​​​It should be noted that in the embodiments of the present application, the eccentric shaft (for example, the first eccentric shaft 707 or the second eccentric shaft 713) refers to the axis of the first end of the shaft (hereinafter referred to as the first axis) and the axis of the second end of the shaft do not coincide. If the eccentric shaft is centered on the first axis, the second end of the eccentric shaft will also rotate around the first axis. Since the eccentric shaft is a mature technology, it will not be described in detail here.

[0060] When using the oscillating assembly 7 proposed in the embodiments, as shown in Figure 5 , first start the first motor 703, which drives the first driving wheel 704 to rotate; further, the first driving wheel 704 drives the first driven wheel 705 to rotate through the first transmission belt 706; further, the first driven wheel 705 drives the first eccentric shaft 707 to rotate. If the first eccentric shaft 707 rotates, the first plate 701 will perform linear reciprocating motion under the guidance of the limiting structure. Since the clamping assembly 3 is arranged on the first plate 701, if the first plate 701 performs linear reciprocating motion, the clamping assembly 3 also performs linear reciprocating motion.

[0061] In the embodiments of the present application, the limiting structure can be any structure that can guide the first plate 701 to perform linear reciprocating motion. For example, the limiting structure includes a sliding rail 709 and a sliding block 710. The sliding rail 709 is arranged on the first plate 701, and the sliding block 710 is arranged on the second plate 702, or the sliding rail 709 is arranged on the second plate 702, and the sliding block 710 is arranged on the first plate 701; the sliding rail 709 and the sliding block 710 are matched.

[0062] In the embodiments of the present application, the sliding rail 709 and the sliding block 710 are matched, which means that during the linear reciprocating motion of the first plate 701, the sliding rail 709 and the sliding block 710 will not easily separate. For example: if the sliding rail 709 is a T-shaped groove, the sliding block 710 can be a T-shaped block; if the sliding rail 709 is a long rod, the sliding block 710 can be a sleeve pipe movably sleeved on the sliding rail 709; as shown in Figure 8 , if the sliding rail 709 is a long rod, the sliding block 710 can include a first pulley 718 and a second pulley 719, and the sliding rail 709 is located between the first pulley 718 and the second pulley 719.

[0063] As can be seen from the above, if the various components of the water sample to be measured in the reaction container 5 can be uniformly contacted with the ultraviolet light, the time for ultraviolet reduction can be reduced. Through a large number of researches of the inventor, it is found that if the reaction container 5 is in a circular tube shape, and the direction in which the clamping assembly 3 performs linear reciprocating motion is parallel to the axis of the reaction container 5, the time for ultraviolet reduction of the water sample to be measured in the reaction container 5 is shorter. That is, in the embodiment, the reaction container 5 can be in a circular tube shape, and when in use, the direction in which the clamping assembly 3 performs linear reciprocating motion is parallel to the axis of the reaction container 5.

[0064] In order to enable the oscillating assembly 7 to drive the clamping assembly 3 to perform rotary oscillation, in an embodiment of the present application, the oscillating assembly 7 can further include a third plate 712, a second motor 714, a second driven wheel 716, and a plurality of second eccentric shafts 713. Specifically, as shown in Figure 6 and Figure 7 The third plate 712 is arranged on the housing 1, and the first plate 701, the second plate 702, and the third plate 712 are arranged in sequence along the vertical direction. One end of each second eccentric shaft 713 is rotationally connected to the second plate 702, and the other end of each second eccentric shaft 713 is rotationally connected to the third plate 712. The second motor 714 is arranged on the third plate 712, and the output end of the second motor 714 is provided with a second driving wheel 715. The second driven wheel 716 is connected to any one of the second eccentric shafts 713, and the second driving wheel 715 and the second driven wheel 716 are in transmission connection through a second transmission belt 717.

[0065] In use, as shown in Figure 7 first, the second motor 714 is started, and the second motor 714 drives the second driving wheel 715 to rotate; further, the second driving wheel 715 drives the second driven wheel 716 to rotate through the second transmission belt 717; further, the second driven wheel 716 drives the second eccentric shaft 713 connected thereto to rotate. If any one of the second eccentric shafts 713 rotates, the other second eccentric shafts 713 will also rotate synchronously. If each second eccentric shaft 713 rotates, the second plate 702 generates rotary oscillation; if the second plate 702 generates rotary oscillation, the first plate 701 also generates rotary oscillation. If the first plate 701 generates rotary oscillation, the clamping assembly 3 arranged on the first plate 701 also generates rotary oscillation.

[0066] It should be noted that in the embodiment of the present application, if only the first plate 701 and the second plate 702 are arranged, the second plate 702 needs to be relatively fixed to the housing 1; if the first plate 701, the second plate 702, and the third plate 712 are arranged, the third plate 712 needs to be relatively fixed to the housing 1.

[0067] In order to facilitate the control of the ultraviolet reduction device, in the embodiments of the present application, as shown in Figure 1 and Figure 2 The ultraviolet reduction device can also include a control box 4. The control box 4 can be electrically connected with the first motor 703, the second motor 714 and the ultraviolet lamp 6. In use, the control box 4 is used to control the opening and closing of the first motor 703, the second motor 714 or the ultraviolet lamp 6. It should be noted that the control of the opening and closing of each electrical component by the control box is a mature technology, which will not be described here.

[0068] It should be noted that the ultraviolet reduction device can be used to store the water sample to be tested in the reaction container, and the ultraviolet lamp can be used to reduce the water sample to be tested. That is, the ultraviolet reduction device can be applied to the application scenario of water quality detection.

[0069] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
