Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a water quality testing sample storage box. Background Technology

[0002] In the field of water quality testing, samples need to go through a certain period of time from collection to testing. During this period, the physical and chemical properties of the samples need to be maintained through storage devices to avoid factors such as temperature fluctuations, cross-contamination, and interference from external impurities from affecting the accuracy of the test results. Therefore, the performance of the sample storage device is directly related to the reliability of water quality test data.

[0003] Existing storage devices mostly use simple insulated boxes to control temperature. Each time a single sample is taken, the top cover of the device must be completely opened, which results in direct contact between the inside of the box and the external environment. This causes a large amount of cold energy to be lost in a short period of time, increasing the workload of the refrigeration module.

[0004] Therefore, a water quality testing sample storage box is proposed to address the above problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a water quality testing sample storage box. By rotating the cover cylinder, the through hole is aligned with the position of one of the storage cylinders. Then, the water quality testing sample bottle inside the storage cylinder is lifted up until the top of the sample bottle protrudes from the through hole. When sampling, only a small through hole is opened to reduce heat loss, effectively reduce the compositional changes of the sample caused by temperature fluctuations, reduce the workload of the cooling module, and ensure the accuracy of the test.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water quality testing sample storage box, comprising: a base, a cover, and a lifting mechanism. A bracket is fixedly installed on the top of the base, and multiple storage cylinders distributed at equal intervals are fixedly installed on the bracket. The cover is rotatably connected to the top of the base, and a top cover is detachably installed on the top of the cover. A refrigeration module is installed inside the cover, and a temperature controller is installed on the side wall of the cover. A through hole is opened on the top cover, and a cover plate is rotatably connected to the top of the top cover. The cover plate covers the top opening of the through hole. The lifting mechanism is installed on the cover, and the lifting mechanism includes a lifting block and a power source for driving the lifting block to move vertically.

[0007] Furthermore, an annular block is installed at the bottom of the cover, and an annular groove is provided at the top of the base.

[0008] Furthermore, multiple hollow grooves are formed on the side walls of each of the storage cylinders.

[0009] Furthermore, a pointer is installed on the outer wall of the cover, and multiple markings are provided on the top of the base near the edge, with each marking corresponding to a different storage cylinder.

[0010] Furthermore, a sliding groove is provided on the inner side wall of the cover cylinder, and the lifting block is slidably connected to the sliding groove.

[0011] Furthermore, the storage cylinder is provided with a clearance groove for the lifting block to pass through.

[0012] Furthermore, the power source includes a track, a connecting rope, and a pair of fixed pulleys. The track is fixed to the outer wall of the cover, and a pressing block is slidably connected to the track. One end of the connecting rope is fixedly connected to the top of the lifting block, and the other end of the connecting rope passes through the cover and is fixedly connected to the pressing block. The pair of fixed pulleys are respectively installed on the inner and outer sides of the cover.

[0013] Furthermore, the weight of the lifting block is greater than the weight of the pressing block.

[0014] The beneficial effects of this utility model are: In this invention, the through hole is aligned with one of the storage cylinders by rotating the cover cylinder, and then the water quality test sample bottle in the storage cylinder is lifted by the lifting mechanism until the top of the sample bottle protrudes from the through hole. When taking samples, only the small through hole is opened to reduce heat loss, effectively reduce the composition changes of the sample caused by temperature fluctuations, reduce the workload of the cooling module, and ensure the accuracy of the test.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] See appendix Figures 1 to 5 As shown, a water quality testing sample storage box in this embodiment includes: a base 1, a cover 2, and a lifting mechanism 6. A bracket 9 is fixedly installed on the top of the base 1, and multiple storage cylinders 10 are fixedly installed on the bracket 9 in an equidistant manner. The cover 2 is rotatably connected to the top of the base 1, and a top cover 4 is detachably installed on the top of the cover 2. A refrigeration module is installed inside the cover 2, and a temperature controller 3 is installed on the side wall of the cover 2. A through hole 11 is opened on the top cover 4, and a cover plate 5 is rotatably connected to the top of the top cover 4. The cover plate 5 covers the top opening of the through hole 11. The lifting mechanism 6 is installed on the cover 2, and the lifting mechanism 6 includes a lifting block 61 and a power source for driving the lifting block 61 to move vertically.

[0019] In this embodiment, the through hole 11 is aligned with one of the storage cylinders 10 by rotating the cover cylinder 2, and then the water quality test sample bottle in the storage cylinder 10 is lifted by the lifting mechanism 6 until the top of the sample bottle protrudes from the through hole 11. When taking samples, only the small through hole 11 is opened to reduce heat loss and effectively reduce the composition change of the sample caused by temperature fluctuations, thus ensuring the accuracy of the test. The top cover 4 is installed on the top of the cover cylinder 2 by means of threaded connection, and a magnetic block is provided on the cover plate 5. A magnet is installed on the top of the cover cylinder 2 to ensure the stability of the cover plate 5 when it is closed. In addition, the cover 2 and the base 1 form a closed space, and multiple storage cylinders 10 are located in this closed space. Together with the refrigeration module and the thermostat 3, they can achieve precise temperature control and maintain a constant low temperature inside.

[0020] See appendix Figure 2 As shown, an annular block is installed at the bottom of the cover 2, and an annular groove is opened at the top of the base 1.

[0021] In this embodiment, the annular groove cooperates with the annular block of the cover to ensure the stable rotation of the cover 2.

[0022] See appendix Figure 4 As shown, multiple storage cylinders 10 have multiple hollowed-out grooves 12 on their side walls.

[0023] In this embodiment, the hollowed-out groove 12 allows constant-temperature air to circulate inside the cover cylinder 2, ensuring uniform sample temperature.

[0024] See appendix Figure 1 As shown, a pointer 7 is installed on the outer wall of the cover 2, and multiple marks 8 are opened on the top of the base 1 near the edge. The multiple marks 8 correspond one-to-one with the positions of multiple storage cylinders 10.

[0025] In this embodiment, the positions of multiple markers 8 and multiple storage cylinders 10 correspond one-to-one. The pointer 7 is aligned with the marker to achieve accurate positioning, eliminating the need to search for samples one by one and avoiding the mistake of taking the wrong sample. Specifically, rotate the cover 2 while observing the pointer 7 on the outer wall of the cover 2. When the pointer 7 is aligned with a certain mark 8 on the edge of the base 1, stop rotating. At this time, the through hole 11 on the top cover 4 is exactly coaxial with the storage cylinder 10 corresponding to the mark 8. Then, use the lifting mechanism 6 to lift the water quality test sample bottle in the storage cylinder 10 until the top of the sample bottle protrudes from the through hole 11.

[0026] See appendix Figure 3 As shown, a sliding groove is provided on the inner side wall of the cover cylinder 2, and the lifting block 61 is slidably connected to the sliding groove.

[0027] In this embodiment, the lifting block 61 directly contacts and lifts the sample bottle, and the sliding groove ensures stable vertical movement.

[0028] See appendix Figure 4 As shown, the storage cylinder 10 has a clearance groove 13 for the lifting block 61 to pass through.

[0029] In this embodiment, the clearance groove 13 provides vertical movement space for the lifting block 61, ensuring that the lifting block 61 can pass through the storage cylinder 10 to contact the sample bottle.

[0030] See appendix Figure 5 As shown, the power source includes a track 65, a connecting rope 62, and a pair of fixed pulleys 63. The track 65 is fixed to the outer wall of the cover 2. A pressing block 64 is slidably connected to the track 65. One end of the connecting rope 62 is fixedly connected to the top of the lifting block 61, and the other end of the connecting rope 62 passes through the cover 2 and is fixedly connected to the pressing block 64. A pair of fixed pulleys 63 are respectively installed on the inner and outer sides of the cover 2.

[0031] In this embodiment, by rotating the cover 2 so that the through hole 11 corresponds to one of the storage cylinders 10, the operator presses down on the pressing block 64 on the track 65 on the outer side of the cover 2: the pressing block slides along the track and transmits the tension through the connecting rope 62; after the connecting rope 62 changes the direction of the force through a pair of fixed pulleys 63 on the inner and outer sides of the cover 2, it pulls the lifting block 61 in the inner sliding groove of the cover 2 to slide upward; the lifting block 61 passes through the clearance groove 13 on the storage cylinder 10 and lifts the water quality test sample bottle in the storage cylinder upward until the top of the sample bottle protrudes from the through hole 11.

[0032] See appendix Figure 5 As shown, the weight of the lifting block 61 is greater than the weight of the pressing block 64.

[0033] In this embodiment, the lifting block 61 has a greater weight than the pressing block 64, thus achieving automatic retraction.

[0034] Working principle: By rotating the cover cylinder 2 to align the through hole 11 with one of the storage cylinders 10, the operator presses down on the pressing block 64 on the track 65 on the outer wall of the cover cylinder 2. The pressing block slides along the track, transmitting tension through the connecting rope 62. After the connecting rope 62 changes the direction of force through a pair of fixed pulleys 63 on the inner and outer sides of the cover cylinder 2, it pulls the lifting block 61 in the inner sliding groove of the cover cylinder 2 upward. The lifting block 61 passes through the clearance groove 13 on the storage cylinder 10, lifting the water quality test sample bottle in the storage cylinder upward until the top of the sample bottle protrudes from the through hole 11. During sampling, only the small-sized through hole 11 is opened to reduce heat loss and effectively reduce the compositional changes of the sample caused by temperature fluctuations, ensuring the accuracy of the test.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
