[0057] As Figure 13 、 Figure 14 、 Figure 15 shown, a third cylinder 51 is fixedly installed on the vertical bracket 5. The output end of the third cylinder 51 is fixedly provided with a triangular block 57. A mounting plate 52 is fixedly provided on the vertical bracket 5. A cylinder 53 is fixedly connected to one side of the mounting plate 52. Symmetrically distributed moving rods 54 are slidably arranged on the cylinder 53.

One end of the compression spring 55 is fixedly connected to the inner wall of the cylinder 53, and the other end is fixedly connected to a right-angled block 56. The right-angled block 56 is fixedly connected to the end of the moving rod 54. A horizontal rod 58 is slidably arranged on the mounting plate 52 and located inside the cylinder 53.

The inclined surface of the inclined surface block 582 is slidably connected to the hypotenuse of the triangular block 57. The horizontal rod 58 is driven to move horizontally by the up and down movement of the triangular block 57. When the horizontal rod 58 moves towards the right-angled block 56, it is slidably connected to the hypotenuse of the right-angled block 56 through the conical surface 581 to push the moving rod 54 to slide outwards of the cylinder 53, so that the moving rod 54 exerts pressure on the inner wall of the water inlet 12 to detect the compressive and impact resistance of the inner wall of the pump body.

[0059] A return spring 59 is fixedly arranged between the inclined surface block 582 and the cylinder 53. The return spring 59 is sleeved on the horizontal rod 58 and is used to push the inclined surface block 582 into contact with the triangular block 57.

[0060] The working principle is as follows:

[0061] By feeding the assembled large-flow flood control pump onto the machine base 2, the pump base 1 slides along the inspection table 21, and the roller 23 conveys the pump base 1 to the position above the inspection table 21 where the large-flow flood control pump is located. At this time, by rotating the double-headed lead screw 29, the two clamping rods 24 are controlled to move towards each other to clamp and fix the pump base 1. When the pump base 1 is clamped well, the water inlet 12 is located outside the cylinder 53. Then, the pressure can be output by the cylinder 1 241 to make the pressing plate 242 located on the pump base 1 to lock the pump base 1 to prevent the pump base 1 from loosening.

[0062] Detection method 1:

[0063] The motor 2 280 is used to control the rotation of the cam 1 28. The cam 1 28 can press one end of the swing rod 26, so that the swing rod 26 rotates intermittently on the cross bar 25. Then, the test rod 27 moves downward for a small distance, and the pump base 1 is detected by impacting the test rod 27 to detect the strength of the pump base 1. After the detection, the support spring 271 drives the test rod 27 to reset.

[0064] Detection method 2:

[0065] The gear 35 on the moving frame 3 is engaged with the rack 61 to control the translation of the U-shaped block 6, so that the detection frame 4 is located on both sides of the pump shell 11. And by rotating the lead screw 1 31, the moving seat 33 and the U-shaped block 6 thereon are driven to move vertically to vertically move the detection position, and then the detection operation is carried out, including rotating the lead screw 2 45 to adjust the clamp 49 at the end of the ejector rod 46 to approach the pump shell 11, so that the clamp 49 clamps the area outside the detection position of the pump shell 11 to position the detection area. Then, the motor 6 470 is used to drive the two cams 2 472 to rotate, alternately pushing the two detection rods 48 to move, so that the detection heads 482 at the ends of the detection rods 48 perform a dynamic and static balance test on the pump shell 11 to detect the balance effect of the pump shell 11 and its internal parts.

[0066] Detection method 3:

[0067] Output thrust through cylinder three 51 to drive the triangular block 57 to move up and down, thereby driving the horizontal rod 58 to move horizontally. When the horizontal rod 58 moves towards the right-angle block 56, it is slidably connected to the hypotenuse of the right-angle block 56 at the conical surface 581, causing the moving rod 54 to gradually slide outwards from the cylinder 53. Apply pressure to the inner wall of the water inlet 12 through the moving rod 54 to detect the compressive and impact resistance of the inner wall of the water inlet 12 of the pump housing 11, and comprehensively test the performance of the large-flow flood control pump.

[0068] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
