It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0036] As Figure 1-2 shown, an underwater test bench for a motor spray pump according to the present invention includes a mounting frame 1 and a motor spray pump 8. A moving frame 3 is connected to the mounting frame 1 through a linear drive member 2;

[0037] The moving frame 3 is connected to an adjusting pipe 5 through an adjusting frame 4 to adjust the use angle of the adjusting pipe 5; the adjusting frame 4 includes a U-shaped frame 41. The U-shaped frame 41 is connected to the moving frame 3 through bolts and nuts, and the U-shaped frame 41 clamps and limits the adjusting pipe 5 through bolts and nuts;

[0038] By adjusting the inclination angle of the adjusting pipe 5 and locking the U-shaped frame 41 through bolts and nuts, the adjusting pipe 5 is clamped, thereby adjusting the angle of the motor spray pump 8.

[0039] The adjusting pipe 5 is connected to a hanging frame 7 through an adjusting mechanism 6; specifically, the adjusting mechanism 6 includes a sleeve 61 and a moving pipe 62. One end of the sleeve 61 is fixedly connected to the adjusting pipe 5, and one end of the moving pipe 62 slides into the inside of the sleeve 61 and is positioned through bolts and nuts.

[0040] A plurality of jacks for bolts to pass through are provided on the sleeve 61, and the jacks are used for multi-stage adjustment of the moving pipe 62. The number of jacks is six, and thus the 6 gears of the motor spray pump 8 can be adjusted.

[0041] The hanger 7 is connected with a limiting mechanism 9 for limiting motors and pumps 8 of multiple models.

[0042] Specifically, the limiting mechanism 9 includes clip pieces 91 and a support platform 92. The support platform 92 is adjustably arranged on the hanger 7. The number of clip pieces 91 is two. One clip piece 91 is fixedly installed on the support platform 92. The two clip pieces 91 are locked by bolts and nuts to clamp and limit the motor and pump 8.

[0043] In an alternative embodiment, a sliding opening is formed in the hanger 7. A bolt passes through the sliding opening and the support platform 92 and is locked by a nut. By providing the sliding opening, the position between the support platforms 92 can be adjusted, so as to be adapted to motors and pumps 8 of different lengths for use.

[0044] In an alternative embodiment, the linear driving member 2 is an electric slide rail or a rodless cylinder.

[0045] Furthermore, a rubber pad is laid on the clip pieces 91. By providing the rubber pad, the clamping stability is increased.

[0046] In an alternative embodiment, the mounting frame 1 is connected with a suspension bracket. By providing the suspension bracket, the entire test bench can be placed into water for detection.

[0047] In the present invention, by changing the angle of the adjusting pipe 5 used within the U-shaped frame 41, the function of changing the use angle is achieved. By changing the length of the moving pipe 62 located inside the sleeve 61, the function of changing the use depth of the motor and pump 8 is achieved, so that it can be used flexibly.
