[0021] 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 of 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.

[0022] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] See also Figure 1-2 As shown, a residual acid recovery device for a charging workshop provided by the utility model includes an acid extraction body 1, and six acid extraction tubes 11 are connected to the bottom side of the acid extraction body 1, one end of the acid extraction tube 11 passes through the bottom side of the acid extraction body 1 and extends upward to a height of 2 cm. The top of the acid extraction tube 11 is set to extend from the bottom side of the acid extraction body to a height of 2 cm, so that a certain amount of acid liquid can be temporarily stored in the acid extraction body 1 when in use; a rubber sleeve 14 is sleeved on the bottom end of the acid extraction tube 11, and the rubber sleeve 14 is used to move up and down along the axial direction of the acid extraction tube 11, so that the position of the rubber sleeve 14 on the acid extraction tube 11 can be adjusted according to needs, so as to control the insertion depth of the acid extraction tube 11 into the battery; an air extraction tube 13 connected to a negative pressure device is arranged on the top of the acid extraction body 1, and a drain pipe 12 is arranged on the bottom of the acid extraction body 1; a handle 15 is arranged on the top of the acid extraction body 1, and a liquid level observation window is arranged on one side of the acid extraction body 1, and the liquid level in the acid extraction body 1 is conveniently observed in time through the arrangement of the liquid level observation window.

[0024] like Figure 3-4 A drainage hole connected to the drainage pipe 12 is provided at the bottom of the acid extraction body 1, and a truncated cone-shaped plug 19 is provided at the drainage hole. Based on the above, it can be known that when needed, the truncated cone-shaped plug 19 is controlled to be removed from the drainage hole, and then the acid temporarily stored in the acid extraction body 1 is discharged by using the drainage pipe 12, that is, it is necessary to control the movement of the truncated cone-shaped plug 19 when in use. At the same time, it can be known that after the acid is discharged, it is necessary to re-control the truncated cone-shaped plug 19 to restore it to block the drainage hole. Therefore, the purpose of the technical solution when it is set is to control the truncated cone-shaped plug 19 to move up and down in the vertical direction.

[0025] That is, a specific method for controlling the vertical upward and downward movement of the truncated cone-shaped plug 19 is provided as follows, wherein a lifting mechanism 17 is arranged directly above the drainage hole, the end of the lifting mechanism 17 is connected to an anti-corrosion rod 18, and the end of the anti-corrosion rod 18 is connected to the truncated cone-shaped plug 19 for blocking the drainage hole; the vertical upward and downward movement of the truncated cone-shaped plug 19 is then controlled by controlling the lifting and lowering of the lifting mechanism 17.

[0027] Specifically, an opening 171 for the anti-corrosion rod 18 to pass through is provided on the bottom side of the cylinder 170 .
