DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a sample storage device for water quality detection, comprising a device body 1, a base 5 is fixed to the bottom end of the inner cavity of the device body 1, a grid plate 2 is fixed to the top of the base 5, the base 5 and the grid plate 2 evenly divide the inner cavity of the device body 1 into a plurality of sample storage cavities, a sealing cover 3 is clamped at the top end of the inner cavity of the sample storage cavity, when the sealing cover 3 is in a clamping state with the inner cavity of the sample storage cavity, the inner cavity of the sample storage cavity is in a sealed state, which is convenient for the storage of samples collected during water quality detection.

[0024] A sleeve 8 adapted to the sample tube is provided in the middle of the bottom of the sample storage cavity, and the sleeve 8 is in an movably connected state with the base 5. When the device is in use, the sampled sample is placed in the sample tube for storage, and the sample tube is clamped in the sleeve 8. When the sealing cover 3 is closed, the top of the sample tube fits tightly with the bottom of the sealing cover 3 to prevent the sample tube from moving in the vertical direction. The bottom of the sealing cover 3 is movably connected with a connecting block 20, and the setting of the connecting block 20 facilitates the rotation of the sample tube.

[0025] Two adjacent sleeves 8 are connected by a connecting structure. In some embodiments of the present application, the connecting structure includes a gear ring 6, a tooth plate 15, a rotating motor 9 and a gear 10. The outer ring of the sleeve 8 is fixedly connected with a gear ring 6, and the gear ring 6, the tooth plate 15 and the gear 10 are all movably connected to the inner cavity of the base 5. The rotating motor 9 is fixedly connected to the base 5, and the end of the output shaft of the rotating motor 9 is fixedly connected with a gear 10. The gear 10 is meshed with a gear ring 6. Two adjacent gear rings 6 are connected by the tooth plate 15. The gear ring 6 and the tooth plate 15 are in a meshing state, and tooth grooves are provided on both sides of the tooth plate 15. The tooth plate 15 is meshed with the gear ring 6 through the tooth grooves.

[0026] From the above description of the connection structure, it can be known that when the rotating motor 9 rotates, it can drive the gear 10 fixedly connected thereto to rotate, and the rotating motor 9 performs reciprocating motion. The gear 10 can drive the sleeve 8 to rotate through the gear ring 6 meshing therewith, and the rotating gear ring 6 can drive other gear rings 6 through the gear plate 15 meshing therewith, that is, the rotation of the rotating motor 9 can realize the rotation of all the sleeves 8 in the device. When the sleeve 8 rotates, the sample tube stuck in the sleeve 8 can rotate, which can avoid precipitation or stratification of the water sample in the sample tube, thereby ensuring the accuracy of sample detection.

[0027] An isolation pad is fixed to the inner wall of the sleeve 8. The isolation pad can be made of rubber. The isolation pad can improve the firmness of the clamping connection between the sample tube and the sleeve 8. A groove 16 is provided at the bottom of the inner cavity of the sleeve 8. An electromagnet 14 is provided at the bottom of the groove. A spring groove is provided at the bottom of the groove 16. A spring 11 is fixedly connected to the inner cavity of the spring groove. The top of the spring 11 is fixedly connected to a push plate 12. The push plate 12 is movably connected to the inner cavity of the groove 16. The thickness of the push plate 12 is the same as the depth of the inner cavity of the groove 16. A buffer pad is fixed to the outer surface of the push plate 12. The buffer pad can be made of rubber. The push plate 12 is provided with an electromagnet 2 13 that matches the electromagnet 14. When the sample tube is in normal use, the push plate 12 and the groove 16 are in contact with each other under the action of the rebound force of the spring 11. The bottom of the inner cavity is in a tightly fitted state. When the sample tube needs to be taken out, currents with opposite flows are passed through the electromagnet 14 and the electromagnet 2 13. When the electromagnet 14 and the electromagnet 2 13 are in a powered-on state, the electromagnet 14 and the electromagnet 2 13 are in a state of magnetic repulsion. Under the action of the repulsive force, the push plate 12 can move away from the electromagnet 14. The push plate 12 can drive the sample tube to move during the movement, and the top of the sample tube can be exposed, which is convenient for the user to take out the sample tube. When taking out the sample tube, the user does not need to put his hand into the sample storage cavity, thereby improving the convenience of using the device.

[0028] The bottom of the inner cavity of the device body 1 is provided with a power cavity, and the inner cavity of the power cavity is connected with a power source 7. The bottom of the power source 7 is provided with a push-pull groove. The setting of the push-pull groove facilitates the disassembly and assembly of the power source 7. The power source 7 can be a lithium battery. When the device is in use, the power source 7 can be used to power the electrical components in the device. A control button 4 is provided on one side of the top of the device body 1, and the user can control the operation of the power source components in the device through the control button 4.

[0029] The inner cavity of the sample storage cavity is provided with a refrigerator 17, a temperature increaser 18 and a temperature detector 19. When the temperature increaser 18 is powered on, the heat emitted can heat the air around the sample and increase the temperature of the sample storage cavity. The refrigerator 17 can be a semiconductor refrigerator, and the hot end of the refrigerator 17 is located outside the device body 1. When the refrigerator 17 is powered on, the refrigerator 17 can cool the air around the sample and reduce the temperature of the sample storage cavity, so that the sample can be stored at the optimal temperature. The temperature detector 19 is used to detect the temperature of the sample storage cavity, so that the user can adjust the temperature in the sample storage cavity.

[0030] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0031] In summary: when the sample storage device for water quality detection is used, the user inserts the sample tube storing the water sample to be tested into the sleeve 8, covers the sealing cover 3, and controls the refrigerator 17 or the heater 18 to work according to the needs. When the refrigerator 17 is working, the air around the sample can be cooled down, and when the heater 18 is working, the air around the sample can be heated up, so that the air temperature around the sample is consistent with the temperature of the sampling location, which is convenient for the storage of the sample. When the sample needs to be taken out, after opening the sealing cover 3, the electromagnet 14 and the electromagnet 2 13 under the sample to be taken out are energized. When the electromagnet 14 and the electromagnet 2 13 are energized, the electromagnet 14 and the electromagnet 2 13 are in a state of magnetic repulsion. Under the action of the repulsive force, the push plate 12 moves up, and the push plate 12 drives the sample tube 12 to move in the process of movement. When the electromagnet 14 and the electromagnet 2 13 are in the energized state, the push plate 12 is reset under the action of the rebound force of the spring 11, which is convenient for the storage of the sample tube. Before the sample is taken out, the rotating motor 9 rotates, and the rotating motor 9 drives the gear 10 fixedly connected thereto to rotate, and the gear 10 drives the gear ring 6 meshing therewith to rotate, and the rotating gear ring 6 drives other gear rings 6 to rotate through the gear plate 15 meshing therewith, and the rotating gear ring 6 drives the sleeve 8 fixedly connected thereto to rotate, and the sleeve 8 drives the sample tube clamped therein to rotate, and the water sample to be tested in the sample tube rotates accordingly, so that the water sample can be shaken evenly, thereby improving the accuracy of water sample detection.
