[0002] Industrial production processes generate large quantities of complex industrial wastewater. To accurately monitor various indicators of industrial wastewater and determine whether it meets discharge standards, sampling and testing of the wastewater are necessary. Proper sample preservation is crucial after collection; improper preservation can lead to sample deterioration and changes in composition, thus affecting the accuracy of test results.

[0003] Currently, most sample preservation boxes on the market have limited functionality and cannot meet the specific needs of industrial wastewater sample preservation. On the one hand, industrial wastewater may possess corrosive or toxic properties, making it difficult for ordinary preservation boxes to effectively prevent sample leakage and posing safety hazards. On the other hand, some industrial wastewater samples have strict temperature requirements, and existing preservation boxes often lack precise temperature control capabilities. Furthermore, different types of industrial wastewater samples need to be stored separately to avoid cross-contamination, but existing preservation boxes lack a reasonable design for this categorization. Therefore, there is an urgent need to design a sample preservation box for industrial wastewater testing that can effectively solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example 1: To address the problem that conventional storage boxes in the prior art are unable to effectively prevent sample leakage, please refer to... Figures 1-7 This utility model provides a technical solution:

[0026] A sample storage box for industrial wastewater testing includes a storage box 1 and a door 2 hinged to the front of the storage box 1. A top cover 3 is fixedly installed on the top of the storage box 1. A storage rack 4 is fixedly connected to the inner wall of the storage box 1. A storage device is provided on the top of the storage rack 4. The storage device includes a sliding mechanism.

[0027] The sliding mechanism includes a slide groove 401, a slider 402, a movable plate 403, a storage box 404, a fixed magnet 405, and a magnetic strip 406. The slide groove 401 is formed on the upper surface of the storage rack 4. The slider 402 is slidably connected to the inner wall of the slide groove 401. The movable plate 403 is fixedly connected to the top of the slider 402. The storage box 404 is fixedly connected to the top of the movable plate 403. The fixed magnet 405 is fixedly connected to the front of the lower surface of the movable plate 403. The magnetic strip 406 is fixedly connected to the front of the top of the storage rack 4. The fixed magnet 405 and the magnetic strip 406 are at the same height, and the sides of the fixed magnet 405 and the magnetic strip 406 that are close to each other attract each other. The storage boxes 404 are evenly distributed on the top of the storage rack 4.

[0028] A cooling tank 5 is fixedly installed inside the storage box 1. Inside the cooling tank 5, a coolant tank 501 and a compressor 502 are also fixedly installed. The output end of the compressor 502 is connected to a connecting pipe 503. A cooling pipe 504 is fixedly connected to the end of the connecting pipe 503 furthest from the compressor 502. The cooling pipe 504 is U-shaped and tightly attached to the bottom of the storage rack 4. The other end of the cooling pipe 504 is connected to the input end of the compressor 502. The coolant inside the coolant tank 501 is water. The compressor 502 is a Panasonic EJ137HGM. By starting the compressor 502, the coolant in the coolant tank 501 is delivered to the cooling pipe 504, which then dissipates heat from the lower surface of the storage rack 4, preventing the storage rack 4 from overheating.

[0029] A collection box 506 is fixedly installed at the bottom of the storage box 1. A drain pipe 507 is fixedly connected to the back of the collection box 506. A one-way valve 505 is installed on the drain pipe 507. The one-way valve 505 only allows liquid to enter the collection box 506 from the drain pipe 507. The top of the drain pipe 507 extends into the interior of the storage box 404.

[0030] When wastewater leaks inside the storage box 404, the wastewater flows into the drain pipe 507 and then into the collection box 506 for collection. This facilitates centralized treatment of the leaked wastewater in the collection box 506. The one-way valve 505 prevents wastewater in the collection box 506 from flowing back into the sample storage box 404, avoiding secondary contamination. The one-way valve 505 is an SS-4-VCR series plastic one-way valve made of PFA plastic, which has excellent corrosion resistance.

[0031] Example 2: To further protect the sample, this application provides a protective mechanism inside the storage box 404. The protective mechanism includes a temperature sensor 4041, a retainer 4042, a rubber sleeve 4043, and a label slot 4044. The temperature sensor 4041 is fixedly installed on the back of the inner wall of the storage box 404. The retainer 4042 is fixedly connected to the left and right sides of the inner wall of the storage box 404. The label slot 4044 is fixedly installed on the front of the storage box 404. The retainers 4042 are evenly distributed inside the storage box 404. A through groove is opened inside the retainer 4042. The rubber sleeve 4043 is fixedly connected to the inside of the through groove.

[0032] Labels can be inserted into the label slot 4044 to facilitate the identification and classification of different types of industrial wastewater samples. The rubber sleeve 4043 can effectively reduce the vibration of the sample during movement and prevent the sample bottle from being damaged by vibration.

[0033] Semiconductor cooling chips 7 are fixedly installed on the left and right sides of the storage box 1. A controller 6 is fixedly installed on the right side of the storage box 1. The controller 6 is connected to the temperature sensor 4041 via a wireless signal. The semiconductor cooling chip 7 is coupled to an external power source.

[0034] When the temperature sensor 4041 detects that the temperature inside the storage box 404 is too high, it sends a high-temperature signal to the controller 6. The controller 6 then connects the semiconductor cooling chip 7 to an external power source, allowing the semiconductor cooling chip 7 to dissipate heat from the storage box 1. The temperature sensor 4041 monitors the temperature inside the storage box 1 in real time and transmits the temperature data to the controller 6. The controller 6 controls the semiconductor cooling heating chip 7 to operate according to a preset temperature range, thereby achieving precise temperature regulation inside the storage box 1 and meeting the storage temperature requirements of different industrial wastewater samples.

[0035] Working principle: When preserving samples of industrial wastewater, first pull the movable plate 403, causing the movable plate 403 to drive the slider 402 to slide inside the slide groove 401. After pulling out the movable plate 403, the fixed magnetic block 405 and the magnetic strip 406 attract each other on the side closest to each other, fixing the movable plate 403. Then, place the test tube containing wastewater inside the preservation box 404, insert the test tube into the through groove in the holder 4042 to preserve the test tube, and finally insert a label inside the label slot 4044.
