[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, with reference to Figure 1-2 as well as Figure 5 , which is the first embodiment of the present utility model, provides an adjusting device, including a supporting mechanism 100, and a lifting mechanism 200 provided on the supporting mechanism 100;

[0028] The supporting mechanism 100 includes a base 101, which is generally disc-shaped;

[0029] The lifting mechanism 200 includes a lifting plate 201 vertically movably arranged on the base 101 , an eccentric plate 202 is arranged at the lower part of the lifting plate 201 , a driving assembly 203 is arranged on the eccentric plate 202 , and a locking assembly 204 is arranged on the driving assembly 203 .

[0030] The lifting plate 201 is in a "T" shape as a whole, and there are two eccentric plates 202, which are symmetrically arranged on both sides of the base 101. The driving component 203 drives the eccentric plate 202 to rotate, and the eccentric plate 202 contacts the lifting plate 201 to drive the lifting plate 201 to move vertically. The lower end of the lifting plate 201 is connected to the impeller shaft of the pump. The numerical movement of the lifting plate 201 drives the impeller shaft to move vertically, thereby adjusting the position of the impeller shaft. After adjusting to the appropriate position, the locking component 204 limits the driving component 203.

[0031] Furthermore, the driving assembly 203 includes a transmission rod 203a provided on the eccentric disk 202, and one end of the transmission rod 203a away from the eccentric disk 202 is engaged with a transmission wheel 203b, and the outer side of the transmission wheel 203b is engaged with an operating disk 203c.

[0032] Furthermore, the driving assembly 203 further includes a handle 203d disposed on the operating panel 203c.

[0033] Furthermore, there are multiple transmission wheels 203b, and the multiple transmission wheels 203b are evenly spaced along the circumference of the transmission rod 203a.

[0034] Since the impeller shaft and impeller of the pump are heavy, it is more laborious to rotate the operating disc 203c. By meshing the operating disc 203c, the transmission wheel 203b and the transmission rod 203a, the rotational torque is increased, making the rotation of the operating disc 203c less laborious.

[0035] Usage process: The impeller shaft and impeller of the pump are in the lowest position due to gravity. Connect the lower end of the lifting plate 201 to the impeller shaft of the pump, rotate the operating plate 203c, and drive the eccentric plate 202 to rotate through the transmission of the transmission wheel 203b and the transmission rod 203a. The eccentric plate 202 squeezes the lifting plate 201 upward to make the lifting plate 201 move upward, thereby driving the impeller shaft and impeller of the pump to move upward to achieve the purpose of adjustment. After the impeller shaft moves to the appropriate position, the locking assembly 204 limits the drive assembly 203, and the operator tightens the adjusting nut on the impeller shaft to complete the adjustment.

[0036] The adjustment device of the present application is lightweight and movable, convenient for operation in a narrow space, and easy to adjust. By designing the structure of the drive assembly 203, the operating force when the impeller shaft and impeller part of the pump are lifted is reduced, thereby making it easy to operate the operating panel 203c.

[0037] Example 2, reference Figure 1-5 , which is the second embodiment of the present utility model. Different from the previous embodiment, the locking assembly 204 includes a ratchet 204a coaxially fixed to the outside of the transmission rod 203a, and a blocking rod 204b is provided on the upper part of the ratchet 204a. The blocking rod 204b is vertically movably arranged on the base 101.

[0038] Furthermore, the lower end of the blocking rod 204b is provided with an inclined surface adapted to the ratchet 204a.

[0039] Usage process: The inclined surface at the lower end of the blocking rod 204b is adapted to the outer end surface of the ratchet 204a, which does not affect the clockwise rotation of the ratchet 204a, but blocks the ratchet 204a from rotating counterclockwise and in the reverse direction. After the impeller shaft of the pump is lifted to the appropriate position, the operating disk 203c is stopped from rotating, and the lower end of the blocking rod 204b blocks the ratchet 204a from rotating in the reverse direction, thereby playing a positioning role.

[0040] Example 3, reference Figure 1 and Figure 5 , which is the third embodiment of the present utility model. Different from the previous embodiment, the lifting mechanism 200 also includes a detection component 205 arranged on the base 101, and the detection component 205 includes a support frame 205a arranged on the upper part of the base 101, and a dial indicator 205b is provided on the support frame 205a. A telescopic rod 205c is provided at the lower part of the dial indicator 205b, and the lower end of the telescopic rod 205c abuts against the lifting plate 201.

[0041] Furthermore, the lifting mechanism 200 further includes a threaded hole 206 disposed at the lower end of the lifting plate 201 .

[0042] The lifting plate 201 is threadedly connected to the impeller shaft of the pump through the threaded hole 206 at the lower end thereof, so that the lifting plate 201 drives the impeller shaft to rise.

[0043] Furthermore, the support mechanism 100 also includes a mounting hole 102 arranged on the base 101, the eccentric disk 202 is vertically arranged in the mounting hole 102, one end of the transmission rod 203a is connected to the eccentric disk 202, and the end of the transmission rod 203a away from the eccentric disk 202 passes through the base 101 and engages with the transmission wheel 203b.

[0044] Furthermore, the support mechanism 100 further includes a positioning slot 103 disposed at the bottom of the base 101 .

[0045] The pump's check disc is provided with a positioning pin, and the positioning groove 103 is used to connect with the positioning pin to fix the regulating device.

[0046] Usage process: A telescopic rod 205c is provided between the dial indicator 205b and the lifting plate 201. When the lifting plate 201 rises, the telescopic rod 205c is driven to retract. The dial indicator 205b displays the retracted length of the telescopic rod 205c, i.e., the lifting height of the impeller shaft of the pump by the lifting plate 201. That is, the change of the axial momentum of the impeller shaft and the position monitoring can be monitored at any time through the dial indicator 205b to ensure the adjustment accuracy.
