Detailed Embodiments

[0032] The following describes in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0033] In the present disclosure, it should be understood that the orientation terms such as "upper" and "lower" are defined based on the drawing direction of the corresponding drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation of the present disclosure. The terms "inner" and "outer" refer to the inside and outside of the corresponding structural contour. The "horizontal direction" and "vertical direction" in the drawings and the text refer to the horizontal direction and vertical direction of the cleaning device, and specific reference may be made to Figure 1 as shown.

[0034] In addition, it should be noted that the terms such as "first" and "second" are used to distinguish one element from another, and do not have sequentiality and importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0035] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected", "coupled", and "installed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0036] In view of this, as Figures 1 to 4As shown in the figure, the present disclosure provides a cleaning device for reagent bottles, including a placement rack 1, a drying member 2, a cleaning tank 3, and a table body 4. The placement rack 1 is used for placing reagent bottles. The drying member 2 is arranged above the placement rack 1 and is used for drying the reagent bottles. The cleaning tank 3 is provided with a plurality of mutually independent accommodating cavities 31, and all of the plurality of accommodating cavities 31 are used for accommodating cleaning liquid for cleaning reagent bottles. The table body 4 has the placement rack 1, the drying member 2, and the cleaning tank 3 all arranged thereon. Among them, the cleaning tank 3 and the placement rack 1 are arranged at intervals in the horizontal direction, and the cleaning tank 3 is arranged on the table body 4 in a vertically position-adjustable manner.

[0037] Through the above technical solution, after the water quality test in the thermal power plant is completed, the operator can place the reagent bottles in different accommodating cavities 31 of the cleaning tank 3. After being cleaned by the cleaning liquid, the reagent bottles are placed on the placement rack 1, and the drying member 2 can dry the cleaning liquid attached to the reagent bottles, thereby realizing the cleaning of the reagent bottles.

[0038] At the same time, since the cleaning tank 3 is provided with a plurality of mutually independent accommodating cavities 31, and all of the plurality of accommodating cavities 31 are used for accommodating cleaning liquid for cleaning reagent bottles, in this way, after the water quality test in the thermal power plant is completed, the reagent bottles containing different reagents can be placed in different accommodating cavities 31 of the cleaning tank 3 for cleaning. In other words, the reagent bottles containing different reagents can be cleaned separately. During the cleaning process of the reagent bottles, different reagents will not mix with each other, effectively avoiding the situation that different reagents are prone to mix with each other and undergo chemical reactions, generating toxic and harmful gases, or even dangerous accidents during the cleaning process of the reagent bottles containing different reagents, and effectively improving the safety during the cleaning process of the reagent bottles.

[0039] Moreover, since the placement rack 1 and the drying member 2 are also arranged on the table body 4 of the above cleaning device, when the reagent bottles are cleaned by the cleaning liquid, the reagent bottles can be placed on the placement rack 1 and dried by the drying member 2. In this way, there will be no residual cleaning liquid on the reagent bottles, and the cleaning effect of the reagent bottles is better.

[0040] In addition, since the cleaning tank 3 and the placement rack 1 are arranged at intervals in the horizontal direction, and the cleaning tank 3 is arranged on the table body 4 in a vertically position-adjustable manner, on the one hand, the placement rack 1 will not interfere with the cleaning of the reagent bottles, effectively avoiding the situation that when the reagent bottles are being cleaned, the placement rack 1 interferes with the reagent bottles and the reagent bottles cannot be placed into the cleaning tank 3. On the other hand, the movable cleaning tank 3 also allows the operator to adjust the height of the cleaning tank 3 when the reagent bottles are being dried, thereby avoiding the situation that the air flow of the drying member 2 blows towards the cleaning tank 3, causing the cleaning liquid in the cleaning tank 3 to splash.

[0041] The present disclosure does not limit the specific connection relationship between the cleaning box 3 and the table body 4, as long as the cleaning box 3 can be vertically position-adjustable on the table body 4. As an implementation manner of the present disclosure, as Figure 1 , Figure 3 and Figure 4 shown, the cleaning device further includes two mounting plates 5 and threaded fasteners 6. The two mounting plates 5 are respectively arranged on opposite sides of the cleaning box 3. A plurality of mounting holes 51 are provided on the mounting plates 5. The plurality of mounting holes 51 are spaced along the vertical direction. Threaded holes are provided at both ends of the cleaning box 3. The threaded fasteners 6 are configured to selectively connect one of the plurality of mounting holes 51 and the threaded holes. The cleaning box 3 is mounted on the two mounting plates 5 through the threaded fasteners 6, and the mounting of the cleaning box 3 on the table body 4 is reliable. In addition, since a plurality of mounting holes 51 are provided on the mounting plates 5 and the plurality of mounting holes 51 are spaced along the vertical direction, in this way, by passing the threaded fasteners 6 through the mounting holes 51 at different positions and connecting them to the threaded holes provided on the cleaning box 3, the adjustment of the mounting height of the cleaning box 3 on the table body 4 can be realized, which is convenient for the operator to adjust the cleaning box to a suitable height, so as to avoid the situation that when the reagent bottle is dried by the drying member 2, the air flow of the drying member 2 blows towards the cleaning box 3, resulting in the splashing of the cleaning liquid in the cleaning box 3.

[0042] In order to further improve the convenience and reliability of the sliding of the cleaning box 3 on the mounting plate 5, optionally, as Figure 2 and Figure 3 shown, a guide groove 52 extending in the vertical direction is further provided on the mounting plate 5. The guide groove 52 is arranged side by side with the plurality of mounting holes 51. A convex block that is snap-fitted with the guide groove 52 is provided at the end of the cleaning box 3.

[0043] In this way, when the cleaning box 3 is connected to the mounting plate 5, both the threaded fasteners 6 and the convex block can play a role in fixing the cleaning box 3, and the fixing effect of the cleaning box 3 on the mounting plate 5 is better. In addition, since the convex block on the cleaning box 3 can be snap-fitted with the guide groove 52 on the mounting plate 5, and the guide groove 52 is arranged side by side with the plurality of mounting holes 51 on the mounting plate 5, the convex block and the threaded fasteners 6 cooperate with each other, which can effectively prevent the cleaning box 3 from shaking or even rotating on the mounting plate 5, and the mounting of the cleaning box 3 on the mounting plate 5 is reliable.

[0044] In addition, the guide groove 52 can also play a guiding role for the convex block provided at the end of the cleaning box 3. In this way, when it is necessary to adjust the height of the cleaning box 3, the operator only needs to move the cleaning box 3, so that the convex block slides in the guide groove 52, and insert the threaded fasteners 6 into the mounting holes 51 at a suitable position and connect them to the threaded holes provided on the cleaning box, then the adjustment of the mounting height of the cleaning box 3 on the table body can be realized, which improves the convenience of the adjustment of the mounting height of the cleaning box 3.

[0045] It should be noted that the present disclosure does not limit the specific structure of the placement rack 1. As an implementation manner of the present disclosure, as Figure 1 and Figure 4 shown, the placement rack 1 includes a first support 11, a first support plate 12, and a test tube base 13. The first support plate 12 is installed on the table body 4 through the first support 11. A plurality of through holes 14 are formed in the first support plate 12, and the test tube base 13 is installed in the through holes 14. The test tube base 13 is used for inserting reagent bottles. In this way, after the reagent bottle is cleaned with the cleaning liquid, the reagent bottle can be inserted into the test tube base 13 provided on the first support plate 12, and the fixing effect of the reagent bottle on the placement rack 1 is better and it will not roll randomly.

[0046] In order to facilitate the installation of the drying member 2 on the placement rack 1 and be able to dry the reagent bottle, optionally, as Figure 1 and Figure 4 shown, the placement rack 1 further includes a second support 15 and a second support plate 16. The second support 15 is arranged on the side of the first support plate 12 away from the table body 4. One end of the second support 15 is connected to the first support plate 12, and the other end of the second support 15 is connected to the second support plate 16. The drying member 2 is arranged on the second support plate 16. In other words, the drying member 2 is arranged above the reagent bottle in the vertical direction. In this way, after the reagent bottle is cleaned with the cleaning liquid, the reagent bottle can be dried under the drying action of the drying member 2 to remove the cleaning liquid attached to the reagent bottle, thereby realizing the cleaning of the reagent bottle.

[0047] In order to facilitate the addition of the cleaning liquid to the accommodating cavity 31 or the replacement of the cleaning liquid in the accommodating cavity 31, optionally, as Figure 3 shown, an inlet 34 and an outlet are provided on the cavity wall of each accommodating cavity 31. The inlet 34 and the outlet are arranged at intervals in the vertical direction. The inlet 34 is arranged above the outlet in the vertical direction. The inlet 34 is used to supplement the cleaning liquid into the accommodating cavity 31, and the cleaning liquid can flow out from the outlet. With such a design, when the cleaning liquid in the accommodating cavity 31 is insufficient, the operator can add the cleaning liquid into the accommodating cavity 31 through the inlet 34 to meet the cleaning requirements of the reagent bottle. In addition, when the cleaning liquid in the accommodating cavity 31 is contaminated due to multiple cleanings, the operator can also discharge the cleaning liquid through the outlet and add new cleaning liquid through the inlet 34 to ensure the cleaning effect of the reagent bottle.

[0048] In order to facilitate the addition of the cleaning liquid to the accommodating cavity 31 through the inlet 34, optionally, as Figure 3As shown, the cleaning device further includes a liquid inlet pipe 7 and a first mounting seat 8. The first mounting seat 8 passes through the inlet 34, and a through first internal threaded hole is formed on the first mounting seat 8. A first external threaded section is formed on the liquid inlet pipe 7. The liquid inlet pipe 7 can be at least partially inserted into the first mounting seat 8 and threadedly connected to the first mounting seat 8. Wherein, a flange 81 is further provided on the side of the first mounting seat 8 away from the liquid inlet pipe 7, and the flange 81 is adapted to be connected to an external pipeline. Through the liquid inlet pipe 7, the cleaning liquid can be added to the cleaning tank 3, and the operation of adding the cleaning liquid into the cleaning tank 3 is relatively simple.

[0049] Moreover, since the liquid inlet pipe 7 and the first mounting seat 8 are threadedly connected, the connection between the threadedly connected liquid inlet pipe 7 and the first mounting seat 8 is reliable, effectively avoiding the situation that the liquid inlet pipe 7 falls off from the cleaning tank 3 during use.

[0050] In addition, since a flange 81 is further provided on the side of the first mounting seat 8 away from the liquid inlet pipe 7, in this way, by connecting the flange 81 to the external pipeline, the liquid inlet pipe 7 can be connected to the external pipeline, thereby realizing the filling of the cleaning liquid.

[0051] Here, it should be noted that the present disclosure does not limit the specific connection relationship of the external pipeline. As an implementation manner of the present disclosure, the above external pipeline is connected to an electric valve, and the automatic addition of the cleaning liquid can be realized through the electric valve.

[0052] Optionally, as Figure 3 shown, the cleaning device further includes a switching valve 9. The switching valve 9 is arranged at the outlet, and the switching valve 9 is used to realize the connection or disconnection of the outlet. On the one hand, the switching valve 9 can connect the outlet and the external environment when the cleaning liquid is discharged, so as to realize the discharge of the cleaning liquid. On the other hand, the switching valve 9 can also close the outlet to avoid the leakage of the cleaning liquid from the outlet.

[0053] In order to avoid the situation that the cleaning liquid remaining on the reagent bottle drips onto the table body 4 or other places when the reagent bottle is placed on the placement rack 1, optionally, as Figure 1 and Figure 4 shown, the above cleaning device may further include a water receiving box 20 and a sponge pad 201 arranged in the water receiving box 20. The water receiving box 20 is arranged below the placement rack 1 in the vertical direction, and the sponge pad 201 is arranged in the water receiving box 20. In this way, even when the reagent bottle is placed on the placement rack 1, the cleaning liquid remaining on the reagent bottle can only drip into the water receiving box 20 and will not drip onto the table body 4 or other places, effectively avoiding the situation that the cleaning liquid remaining on the reagent bottle drips randomly and easily contaminates the table body 4 and the on-site environment.

[0054] In addition, the sponge pad 201 can also buffer the dripping residual cleaning liquid, effectively preventing the cleaning liquid from splashing everywhere, and further avoiding the situation that the cleaning liquid remaining in the reagent bottle easily contaminates the table body 4 and the on-site environment.

[0055] For the convenience of the operator to store the reagent bottle and / or the tools required for cleaning the reagent bottle, optionally, as Figure 4 shown, the cleaning device may further include a storage cabinet 30. The storage cabinet is arranged at the lower part of the table body 4. The storage cabinet 30 includes a cabinet body 301, a cabinet door 302 and a partition board 303. The cabinet door 302 is rotatably connected to the cabinet body 301. The partition board 303 is arranged inside the cabinet body 301 and is used to partition the storage space inside the cabinet body 301. The storage cabinet 30 can be used to store the cleaned reagent bottles and / or the tools required for cleaning the reagent bottles, without the need for an independent storage device.

[0056] In addition, since the partition board 303 is arranged inside the cabinet body 301 and the partition board 303 is used to partition the storage space inside the cabinet body 301, in other words, through the partition board 303, the reagent bottles and / or the tools required for cleaning the reagent bottles can be classified and placed. In this way, when the reagent bottles and / or the cleaning of the reagent bottles are needed, the operator can directly find the classified reagent bottles and / or cleaning tools, effectively saving time and having a high efficiency.

[0057] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0058] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, without conflict, they can be combined in any suitable way. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0059] In addition, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
