Description

Technical Field

[0001] This utility model relates to the technical field of water quality testing equipment, specifically a sample storage cabinet for water quality testing. Background Technology

[0002] Water quality testing plays a vital role in ensuring environmental safety, public health, and the rational use of water resources. Whether testing surface water (such as rivers and lakes), groundwater, or drinking water sources, the composition of water samples can easily change if they are not properly preserved after collection. Therefore, sample preservation cabinets are necessary.

[0003] Existing technology discloses a sample storage cabinet for water quality testing, with announcement number CN219905179U. The cabinet includes a storage mechanism comprising a storage box body. A mesh partition is fixedly installed inside the storage box body, and a placement block is fixedly installed on the top of the mesh partition. Sample tube bodies are placed inside the placement block. A cooling mechanism, comprising a water tank and a fan, is located on the right side of the storage box body. This device, through its storage mechanism, can store multiple sample tube bodies. The cooling mechanism lowers the temperature inside the storage box body, preventing excessive temperature from causing bacterial growth. The movable mechanism allows for the deployment of casters, facilitating device movement. This solves the problems of existing water quality testing sample storage cabinets, such as difficulty in controlling ambient temperature, high temperatures leading to bacterial growth and affecting test results, and limited capacity for holding test tubes.

[0004] The aforementioned water quality testing sample storage cabinet can cool the temperature inside the storage tank to prevent excessive temperature from causing bacterial growth. However, the device controls the temperature by refrigeration, which changes the internal condition of the water after refrigeration, potentially affecting the accuracy of subsequent testing and processing. Therefore, its performance is not ideal and needs improvement. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This water quality testing sample storage cabinet is equipped with an internal heat preservation device. When the water pump is started, the water inside the tank is drawn out and then enters the circulation conveying pipeline. The water is then atomized and sprayed out through the circulation conveying pipeline, which can reduce the internal temperature and achieve the purpose of cooling. This makes it easier to preserve water quality samples. Moreover, no refrigeration method is used to control the temperature, so it will not affect the accuracy of subsequent testing and processing.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A sample storage cabinet for water quality testing includes a cabinet body 1, a cabinet door 2 hinged to the front of the cabinet body 1, an internal insulation device 3 installed inside the cabinet body 1, and a clamping device 4 installed on the back of the internal insulation device 3.

[0026] The internal insulation device 3 includes a placement plate 301, a temperature detection housing 302, a water tank 303, a water pump 304, a connecting water pipe 305, a circulation conveying pipe 306, and an atomizing nozzle 307. The placement plate 301 is fixedly connected to both sides of the interior of the cabinet 1. The temperature detection housing 302 is fixedly connected to the top center of the placement plate 301. The water tank 303 is fixedly connected to the top of the placement plate 301, and the back of the water tank 303 is fixedly connected to the front of the temperature detection housing 302. The water pump 304 is fixedly connected to the top of the water tank 303. The connecting water pipe 305 is fixedly connected to the front of the water pump 304, and the end of the connecting water pipe 305 away from the front of the water pump 304 is fixedly connected to... The top of the water tank 303 is connected to the inside of the water pump 304 via a circulating conveying pipe 306. The atomizing nozzle 307 is fixedly connected to the bottom of the circulating conveying pipe 306. A sealing ring is provided on the front of the surface of the temperature sensor, which is connected to the back of the water tank 303. The temperature sensor is a DS18B20 model. The atomizing nozzles 307 are evenly distributed laterally at the bottom of the surface of the circulating conveying pipe 306. Multiple atomizing nozzles 307 spray evenly to reduce omissions and achieve uniform cooling. The temperature sensor is fixedly connected to the front of the temperature detection housing 302. The front of the temperature sensor extends through the back of the water tank 303 and connects to the inside of the water tank.

[0027] The clamping device 4 includes a back end connecting plate 401, a spring member 402, a front end connecting plate 403, and an anti-slip elastic connecting pad 404. The top of the placement plate 301 has a placement groove. The back end connecting plate 401 is fixedly connected to the top of the placement plate 301 near the back. The spring member 402 is fixedly connected to the front of the back end connecting plate 401. The front end connecting plate 403 is fixedly connected to the front of the spring member 402. A pressing plate is fixedly connected to the side of the front end connecting plate 403. The anti-slip elastic connecting pad 404 is fixedly connected to the front of the pressing plate. The pressing plate is used to clamp the internal water quality sample. The anti-slip elastic connecting pad 404 on the front can prevent damage. The back area of ​​the front end connecting plate 403 is equal to the front area of ​​the back end connecting plate 401. The end of the spring member 402 away from the front of the back end connecting plate 401 is fixedly connected to the back of the front end connecting plate 403.

[0028] In use, place the water quality sample that needs to be kept in place on top of the placement plate 301, and place the water quality sample inside the placement groove provided on the top of the placement plate 301. Before placing, hold the front connecting plate 403 and press it backward to leave space for the water quality sample. After the water quality sample is placed, release the front connecting plate 403 until the front is in contact with the back of the sample for clamping. The anti-slip elastic connecting pad 404 can prevent damage. Then, the internal insulation device 3 can be used for heat preservation. A water inlet is provided on the top of the back of the water tank 303, and the temperature detection housing 302 has a temperature detection sensor on the front. The sensor extends into the water tank 303 to detect the water inside. Since the water in the tank 303 is also located inside the cabinet 1, its temperature is the same as that of the water sample. The temperature is monitored in real time. If the temperature is too high, it indicates that the temperature of the water sample inside is also too high. To avoid the water sample being affected by the high temperature, the water pump 304 can be started to extract the water from the tank 303 and then send it into the circulation pipeline 306. The circulation pipeline 306 is used to divert and atomize the water, which can reduce the internal temperature and achieve the purpose of cooling. This makes it easier to preserve the water sample. Moreover, no refrigeration is used when controlling the temperature, so it will not affect the accuracy of subsequent detection and processing. The effect is good.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
