Specifically, the membrane pump 104-4 is configured to transfer the brine entering the membrane pump 104-4 to the constant temperature adsorption system 103, and after the constant temperature adsorption system 103 selectively adsorbs the inflow brine, obtain lithium or other elements to be extracted, so that the brine entering the constant temperature adsorption system 103 can be discharged out of the adsorption collection device platform through the drainage system.
Further, since the mobile adsorption collection device is disposed in a salt lake or a salt pan, in order to enable the brine collector 104-1 to extend into a collection source, preferably, a telescopic device 104-2 is disposed at one end of the brine collector 104-1, and the length of the brine collector 104-1 can be automatically prolonged or the length of the brine collector 104-1 can be automatically shortened by the telescopic device 104-2, so that in operation, the length of the brine collector 104-1 can be automatically adjusted according to the distance between the mobile adsorption collection device and a water source. Further, the first floating ball 201 is further disposed at one end of the brine collector 104-1 extending into the collecting source, through the first floating ball 201, the brine collector 104-1 can be vertically suspended at the top end of the telescopic device 104-2, that is, the first floating ball 201 is disposed, the brine collecting system 104 and the top end of the telescopic device 104-2 are in flexible connection, the brine collector 104-1 can sink into the brine with different depths, finally, the problem that the water collecting quality is affected due to the fact that the brine collector 104-1 floats on the surface of the collecting source is avoided, and the operation depth of the brine collector 104-1 is not limited.
In practical application, because the depth of the brine collecting source is different, the concentration of the brine is gradually reduced from deep to shallow along with the change of the depth of the brine collecting source. In order to avoid the influence of the brine collector 104-1 and the brine conveying pipeline 104-5 on the underwater sinking depth due to the problem of underwater buoyancy, preferably, the brine collecting system 104 further comprises a metal trolley 104-6, the brine collector 104-1 and the brine conveying pipeline 104-5 are arranged on the metal trolley 104-6, the brine collector 104-1 and the brine conveying pipeline 104-5 can be sunk under the water through the metal trolley 104-6, and moreover, the brine collecting pipe orifice can be prevented from being inserted into a salt layer during operation through the metal trolley 104-6; further, in order to facilitate the movement of the metal trolley 104-6 under water, a metal roller 104-7 is further provided at the bottom of the metal trolley 104-6, and the metal trolley 104-6 can be conveniently moved under water by the metal roller 104-7.

The tail liquid discharging system 105 also comprises an automatic telescopic rod 105-1 and a second floating ball 105-2, when the operation of the movable adsorption collection equipment platform is carried out, tail liquid generated by the constant temperature adsorption system 103 is returned to the salt lake or the salt field through the tail liquid discharging system 105 communicated with the automatic telescopic rod 105-1, and the automatic telescopic rod 105-1 can float on the surface of a collection source through the second floating ball 105-2, so that tail liquid brine is discharged into brine on the surface of the collection source.
It should be noted that, in the present invention, the distance between the side of the mobile carrier 101 where the brine collecting system 104 and the tail liquid discharging system 105 are disposed and the collecting source is smaller than the distances between the other sides and the collecting sources.
