[0028] Drive unit includes connecting ring 304 and torsional spring 303 being sleeved on rotating shaft 3, connecting ring 304 is fixedly connected on one end of rotating shaft 3 through tank body 1 lower end portion, and one end of torsional spring 303 is fixedly connected with the bottom of tank 1, and the other end is fixedly connected with connecting ring 304;Further comprising limiting pin 305, limiting pin 305 is six prismatic type setting, and fixedly installed on the lower end surface of sealing cover 101, and the upper end portion of rotating shaft 3 is set with the limiting groove 306 corresponding with limiting pin 305.
[0029] The sealing cover 101 is fixedly connected with a sealing ring 2, the sealing ring 2 is inserted into the tank body 1, a sealing gasket 201 is fixedly installed on the outer wall of the sealing ring 2, and the sealing gasket 201 is attached to the inner wall of the tank body 1.
[0030] The outer wall of the sealing ring 2 is provided with an air bag 202 around, the upper end inner wall of the tank body 1 is provided with a sealing groove 203 matched with the air bag 202, a booster pump 204 is fixedly installed on the tank body 1, and the output end of the booster pump 204 is connected with the air bag 202 through a gas pipe one 205.
[0031] The one end of a gas pipe two 206 away from the rotary joint 403 is connected with the air bag 202, and the gas pipe two 206 is provided with an electromagnetic valve.
[0032] Firstly, the sealing cover 101 installed on the tank body 1 is opened, the operation releases the connection constraint between the sealing cover 101 and the tank body 1, and prepares for subsequent storage of nutrient solution;
[0033] After the sealing cover 101 is opened, the nutrient solution prepared to be stored is poured into the tank body 1 through the opening of the tank body 1, when the storage of the nutrient solution is completed, the sealing cover 101 is reinstalled on the tank body 1, at this time, the sealing ring 2 is inserted into the tank body 1 along with the sealing cover 101, so that the sealing gasket 201 is extruded by the sealing ring 2 and attached to the inner wall of the tank body 1, thereby increasing the sealing performance of the connection between the sealing cover 101 and the tank body 1, which can not only prevent the nutrient solution in the tank from leaking, but also prevent foreign matters from entering the tank body 1, thereby ensuring the quality of the nutrient solution;
[0034] At the same time, in the process of reinstalling the sealing cover 101 on the tank body 1, as the sealing cover 101 gradually approaches the tank body 1, the limiting pin 305 on the lower end surface of the sealing cover 101 is inserted into the limiting groove 306, then the sealing cover 101 is rotated, due to the cooperation between the limiting pin 305 and the limiting groove 306, the sealing cover 101 can drive the rotary shaft 3 and the connecting ring 304 to rotate in the process of rotating, at the same time, the connecting ring 304 twists the torsional spring 303 sleeved on the rotary shaft 3 in the process of rotating, so that the torsional spring 303 is charged, until the sealing cover 101 is completely installed on the tank body 1, at this time, the torsional spring 303 stores a certain elastic potential energy, so as to prepare for driving the rotary shaft 3 to rotate when the sealing cover 101 is opened;
[0035] At the same time, after the sealing cover 101 is installed in place, the booster pump 204 is started, the booster pump 204 sends the gas into the air bag 202 through the gas pipe one 205, so that the air bag 202 is inflated and closely attached to the sealing groove 203, thereby further increasing the sealing performance of the connection between the sealing cover 101 and the tank body 1, improving the sealing performance of the tank body 1, effectively avoiding the nutrient solution in the tank from being polluted by external microorganisms, and thereby better ensuring the quality of the nutrient solution, then the booster pump 204 is closed.
[0036] When the nutrient solution stored in the tank 1 needs to be taken out, first open the electromagnetic valve on the gas pipe two 206, at this time the gas in the air bag 202 is transported into the gas cavity 401 through the gas pipe two 206, hollow cavity 4 in turn, and finally sprayed out through the air jet hole 402, so that the sprayed gas impacts the nutrient solution in the tank to produce flow, and promotes the uniform dispersion of various components of the nutrient solution settled at the bottom of the tank 1. Then remove the sealing cover 101 installed on the tank 1. After the sealing cover 101 is opened, the rotating shaft 3 begins to rotate under the action of the torsional spring 303 (the limit pin 305 is separated from the limit slot 306, and the torsional spring 303 releases the elastic potential energy), driving the elastic rod 301 and the counterweight 302 to rotate, so as to stir the nutrient solution in the tank, and further promote the uniform dispersion of various components of the nutrient solution in the tank 1.
[0037] At the same time, when the rotating shaft 3 rotates, the counterweight 302 is affected by the centrifugal force. When the torsional spring 303 just starts to release the elastic potential energy, the stored energy is sufficient to provide a larger torque for the rotating shaft 3 to drive the rotating shaft 3 to rotate quickly. When the rotating speed is fast, the centrifugal force increases, the elastic rod 301 stretches outward, and as the elastic potential energy of the torsional spring 303 is gradually released, the torque provided by the torsional spring 303 gradually decreases, and the rotating speed of the rotating shaft 3 also gradually decreases. The centrifugal force decreases, and the elastic rod 301 contracts, so that it can continuously change the stirring range and intensity in the tank, further enhancing the stirring effect of the nutrient solution in the tank, so as to fully and more thoroughly mix the nutrient solution at different positions in the tank, ensuring that the proportion of various components in each portion of the nutrient solution taken out is uniform and consistent, and ensuring that the nutrient solution can play a stable and effective role in use. Then, a tool (such as a spoon) can be used to scoop the nutrient solution from the opening of the tank 1 into the tank 1.
[0038] Example 2: Refer to Figure 1 , Figure 5 A nutrient solution storage device for microalgae cultivation, which is basically the same as example 1, and further, a plurality of positioning pins 102 are fixedly connected to the lower end surface of the sealing cover 101 at equal distances, and a plurality of positioning slots corresponding to the positioning pins 102 are formed in the upper end of the tank 1, and the positioning pins 102 are inserted into the positioning slots.
[0039] When installing the sealing cover 101, align the positioning pins 102 on the lower end surface of the sealing cover 101 with the positioning slots on the upper end of the tank 1, then lower the sealing cover 101, and the positioning pins 102 are inserted into the positioning slots. This improves the accuracy and convenience of installing the sealing cover 101, ensures the stability of the connection between the sealing cover 101 and the tank 1, and thus improves the sealing performance of the tank 1. When disassembling, reverse the operation and lift the sealing cover 101 to separate the positioning pins 102 from the positioning slots.
[0040] Example 3: Refer to Figure 1 , Figure 3A kind of nutrient solution storage device for microalgae cultivation, substantially same with embodiment 1, further include activated carbon filter element, activated carbon filter element is set to the input end of booster pump 204;
[0041] Through the setting of activated carbon filter element (not shown in the figure), so that the outside air enters booster pump 204 first through activated carbon filter element, since activated carbon has abundant pore structure, can adsorb harmful substances and impurities in air, play the role of purifying air, then, filtered air enters booster pump 204 again, to ensure that the gas entering air bag 202 is pure, avoid impurities into air bag 202 affect its sealing performance, also prevent impurities from entering tank 1 and polluting nutrient solution.
[0042] Embodiment 4: refer to Figure 1 、 Figure 2 、 Figure 3 A kind of nutrient solution storage device for microalgae cultivation, substantially same with embodiment 1, further include rotating handle 5, the rotating handle 5 is fixedly connected on the upper of sealing cover 101;Through the setting of rotating handle 5, increase the force arm of operating personnel's force, so that operating personnel can more easily rotate sealing cover 101, improve the convenience of operation.
