Description

Technical Field

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

[0002] Water quality testing is the process of assessing the physical, chemical, and biological properties of water bodies in order to determine their safety, suitability, and health status. It is widely used in many fields such as drinking water safety, environmental protection, industrial production, aquaculture, agricultural irrigation, and recreation. When testing water quality, samples need to be collected and placed in containers, which are then stored and transported using storage devices.

[0003] Existing patent CN222474863U discloses a sample storage device for water quality testing. It utilizes a battery to power a semiconductor cooling chip and an exhaust fan. The semiconductor cooling chip and exhaust fan can cool the inner wall of the storage box through heat transfer, preventing excessively high temperatures inside the box. Simultaneously, a knob drives a connecting rod and a bidirectional lead screw to rotate. The bidirectional lead screw, through a threaded plate, drives a clamping block and a second protective layer to secure the container holding the water sample inside the storage tank, preventing it from shaking. This invention provides low-temperature preservation, preventing water samples from deteriorating due to excessively high temperatures during storage and transportation, thus improving the accuracy of water quality testing results. Furthermore, this device facilitates the securing of the container holding the water sample, preventing tilting, damage, and loss during transportation, thus improving the efficiency of water quality testing.

[0004] The aforementioned patent has certain drawbacks: since both ends of multiple bidirectional lead screws are fixedly connected and multiple fixing mechanisms are linked and must operate synchronously, it is impossible to adjust individual containers independently when dealing with containers of different sizes. This results in smaller containers not being able to be effectively clamped and fixed, and they are prone to tilting, collisions, or even damage during transportation, causing sample loss and affecting the reliability and efficiency of water quality testing. Therefore, a sample storage device for water quality testing is proposed. Utility Model Content

The base is constructed with a through groove, in which a semiconductor cooling chip, a storage battery, and a fan are arranged.

[0008] Furthermore, a rubber block is provided on the inner side of the clamping plate.

[0009] Furthermore, the fixed frame is slidably provided with a support frame equal in number to the placement holes, the support frame is constructed with an arc-shaped groove, a compression spring is provided between the support frame and the fixed frame, and the fixed frame is provided with a locking member for simultaneously locking or unlocking multiple support frames.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1-6 As shown, an embodiment of the present invention provides a sample storage device for water quality testing, including a base 1 and a cover 2, which are fastened together and connected by a latch. When the base 1 and the cover 2 are fastened together, a storage cavity is formed between them.

[0026] The distinguishing technical features of this utility model also include: a fixing frame 3 is provided on the base 1, the fixing frame 3 is fixed on the base 1 and located in the storage cavity, the fixing frame 3 is provided with an equal number of placement holes 4 and annular plates 5, the placement holes 4 and annular plates 5 are coaxially distributed and their axes are both vertical, the annular plates 5 are fixed on the fixing frame 3, and multiple arc-shaped rods 6 are slidably arranged on the annular plates 5. The arc-shaped rods 6 slide in the horizontal direction and are arranged in a circular array around the axis of the annular plates 5. A V-shaped clamping plate 7 is provided at the free end of the arc-shaped rods 6. The clamping plate 7 is vertical and fixed at the free end of the arc-shaped rods 6. A composite clamping device is provided between the clamping plate 7 and the annular plates 5. The return spring 8 is horizontal and sleeved on the arc-shaped rod 6. The two ends of the return spring 8 are fixedly connected to the clamping plate 7 and the ring plate 5 respectively. The ring plate 5 is provided with a driving component for driving multiple arc-shaped rods 6 to slide synchronously in the center. The base 1 is constructed with a through groove 9. The through groove 9 is provided with a semiconductor cooling chip 10, a storage battery 11 and a fan 12. The semiconductor cooling chip 10, the storage battery 11 and the fan 12 are all fixed in the through groove 9. The semiconductor cooling chip 10 has a cold end and a hot end that are relatively distributed. The cold end faces the storage cavity and the hot end faces the through groove 9. The storage battery 11 supplies power to the semiconductor cooling chip 10 and the fan 12.

[0027] In the initial state, all the arc-shaped rods 6 are far from the axis of the ring plate 5, and the return spring 8 is in its natural state. During use, the container containing the sample is vertically passed through the placement hole 4 until the top of the container abuts against the fixing frame 3. The driving component drives the multiple arc-shaped rods 6 to slide synchronously in the center, and the multiple arc-shaped rods 6 synchronously approach the axis of the ring plate 5. The arc-shaped rods 6 drive the clamping plates 7 to move together, and the return spring 8 is compressed until the inner sides of all the clamping plates 7 abut against the outer wall of the container, thus fixing the container and preventing tilting, collision, and damage during transportation. Then, the cover 2 is fastened onto the base 1, and the base 1 and cover 2 are locked together by the latch. The battery 11 supplies power to the semiconductor... The thermoelectric cooler 10 and fan 12 are powered. The thermoelectric cooler 10 works, the cold end cools the storage chamber, and the hot end dissipates heat. The fan 12 works, and outside air passes through the channel 9 and carries away the heat, keeping the storage chamber in a low-temperature environment to prevent the water sample from deteriorating due to high temperature during storage. Then it is transported. After being transported to the designated location, the cover 2 and the base 1 are separated. The drive component releases the drive of multiple arc rods 6, and multiple reset springs 8 are reset to their natural state. The arc rods 6 slide away from the axis of the ring plate 5, driving the clamping plate 7 to move away from the outer wall of the container, so that the container can be released and the container can move upward to exit the placement hole 4, so that the water sample can be operated on in subsequent steps.

[0028] In summary, this utility model allows for the low-temperature storage of water samples, preventing them from deteriorating due to high temperatures during storage and ensuring the accuracy of water quality test results. It also allows for the securing of containers of different sizes, preventing tilting, collisions, and damage during transportation, thus avoiding sample loss and ensuring the reliability and efficiency of water quality testing. Therefore, it is highly practical.

[0029] like Figure 3 As shown, a further technical solution of the present invention is disclosed, wherein a rubber block 13 is provided on the inner side of the clamping plate 7, and the rubber block 13 is fixed on the inner side of the clamping plate 7.

[0030] Referring to the above, in the initial state, the rubber block 13 is in a natural state. When the inner side of the clamping plate 7 and the outer wall of the container come into contact and overlap, the rubber block 13 will deform and fit tightly against the outer wall of the container. This not only increases the friction and improves the clamping stability, but also avoids damage to the container caused by rigid clamping. Conversely, when the clamping plate 7 moves away from the outer wall of the container, the rubber block 13 returns to its natural state.

[0031] like Figure 4 As shown, a further technical solution of this utility model is disclosed. The fixed frame 3 is slidably provided with a support frame 14 of the same number as the placement hole 4. The support frame 14 slides in the vertical direction. The support frame 14 is constructed with an arc-shaped groove 15. The arc-shaped groove 15 and the placement hole 4 are coaxially distributed. A compression spring 16 is provided between the support frame 14 and the fixed frame 3. The compression spring 16 is in the vertical direction and its two ends are fixedly connected to the support frame 14 and the fixed frame 3 respectively. The fixed frame 3 is provided with a locking member for locking or unlocking multiple support frames 14 simultaneously.

[0032] Referring to the above, in the initial state, multiple support brackets 14 are simultaneously unlocked by the locking mechanism, the support brackets 14 are in the highest position, and the compression spring 16 is in the natural state. When the container passes vertically through the placement hole 4 and the top of the container abuts against the fixing frame 3, the bottom of the container will be located in the arc groove 15. The container drives the support brackets 14 to slide downward, and the compression spring 16 is compressed. Then, multiple support brackets 14 are simultaneously locked by the locking mechanism, and the support brackets 14 cannot slide. The compression spring 16 remains in the compressed state to meet the storage needs of containers of different lengths. Conversely, after being transported to the designated location, multiple support brackets 14 are simultaneously unlocked by the locking mechanism. When the container moves upward to exit the placement hole 4, the bottom of the container exits the arc groove 15, the compression spring 16 returns to the natural state, and the support brackets 14 slide upward to the highest position due to elastic potential energy.

[0033] like Figure 4As shown, the specific structure of the locking component of this utility model is disclosed. The locking component includes a slide plate 17 that is slidably disposed on a fixed frame 3. The slide plate 17 slides in the horizontal direction. A locking screw 18 that is threaded through the slide plate 17 is rotatably disposed on the fixed frame 3. The locking screw 18 is in the horizontal direction. An abutting block 19 that is equal in number to and abuts against the support frame 14 is disposed on the slide plate 17. The abutting block 19 is in the horizontal direction and fixed on the slide plate 17. The abutting block 19 is arc-shaped.

[0034] Referring to the above, in the initial state, the slide plate 17 is in the initial position, and the contact block 19 is away from the support frame 14. In use, manually driving the locking screw 18 to rotate forward, the slide plate 17 slides to the limit position due to the thread action, and the contact block 19 and the support frame 14 abut and overlap. Due to the obstruction of the contact block 19, the support frame 14 cannot slide upward under the action of elastic potential energy, so as to realize the synchronous locking of multiple support frames 14. Conversely, manually driving the locking screw 18 to rotate in reverse, the slide plate 17 slides to the initial position due to the thread action, and the contact block 19 moves away from the support frame 14, so as to unlock multiple support frames 14 synchronously.

[0035] like Figure 3 As shown, the specific structure of the driving component of this utility model is disclosed. The arc rod 6 is provided with a transition slope 20. The driving component includes a screw cylinder 21 threaded on the ring plate 5. The screw cylinder 21 and the ring plate 5 are coaxially distributed. The ring plate 5 is provided with a threaded groove. The screw cylinder 21 and the threaded groove are threadedly engaged. The screw cylinder 21 is provided with a guide cone surface 22 that abuts against and overlaps with the transition slope 20.

[0036] Referring to the above, in the initial state, the screw cylinder 21 is in the lowest position. When in use, the screw cylinder 21 is manually driven to rotate upward. Through the cooperation of the guide cone surface 22 and the transition slope 20, multiple arc-shaped rods 6 are forced to move synchronously closer to the axis of the ring plate 5, so as to drive multiple arc-shaped rods 6 to slide synchronously in the center. Conversely, when the screw cylinder 21 is manually driven to rotate downward to the lowest position, multiple return springs 8 are returned to their natural state, and the arc-shaped rods 6 slide away from the axis of the ring plate 5.

[0037] like Figure 6 As shown, a further technical solution of the present utility model is disclosed. A sealing gasket 23 is provided between the cover 2 and the base 1. The sealing gasket 23 is fixed on the base 1. A heat insulation coating is provided on the inner wall of the cover 2. The heat insulation coating is applied to the inner wall of the cover 2. The heat insulation coating is not shown in the accompanying drawings.

[0038] Referring to the above, during use, the sealing gasket 23 can improve the sealing of the storage cavity, and the heat insulation coating can block heat conduction, thereby reducing the loss of cold energy in the storage cavity.

[0039] like Figure 5As shown, a further technical solution of this utility model is disclosed. The cold end of the semiconductor refrigeration chip 10 is provided with a heat-conducting plate 24. The heat-conducting plate 24 is horizontal and fixed on the base 1. The heat-conducting plate 24 and the cold end of the semiconductor refrigeration chip 10 are in contact and overlap. The heat-conducting plate 24 has a cavity, which is filled with thermally conductive silicone grease 25. The thermally conductive silicone grease 25 is a thermally conductive silicone grease composite made of organosilicone as the main raw material and added with materials with excellent heat resistance and thermal conductivity. It is a high thermal conductivity insulating organosilicone material with excellent thermal conductivity. The heat-conducting plate 24 is provided with multiple thermally conductive fins 26. The multiple thermally conductive fins 26 are all fixed on the side of the heat-conducting plate 24 away from the semiconductor refrigeration chip 10 and are evenly distributed.

[0040] Referring to the above, when the semiconductor cooling chip 10 is working, the heat conduction efficiency can be improved through the combined action of the heat-conducting plate 24, the thermal grease 25 and the multiple heat-conducting fins 26, thereby improving the cooling effect on the storage cavity.

[0041] like Figure 6 As shown, a further technical solution of this utility model is disclosed. Both ends of the through groove 9 are detachably provided with filter screen plates 27 by bolts. The filter screen plates 27 are vertical and have a first surface and a second surface connected together. The first surface is inserted into the through groove 9 and the second surface abuts against the base 1. The filter screen plates 27 are constructed with through holes and the base 1 is constructed with threaded holes. The free end of the bolt passes through the through hole and is threaded into the threaded hole.

[0042] Referring to the above, during use, the filter screen 27 can filter impurities in the air, preventing impurities from entering the channel 9 and affecting the normal operation of the semiconductor cooling chip 10, the battery 11, and the fan 12. When not in use, the filter screen 27 can be disassembled for cleaning.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
