[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] In order to facilitate the detection of the service life of propeller 2, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a mounting cover plate 1 is arranged on the upper surface of a water pool for detecting a propeller 2; a supporting frame 3 is arranged on the surface of the mounting cover plate 1; a rotating assembly is arranged in the water pool and is used to drive the propeller 2 to perform circular motion in the water pool; a power mechanism, whose power output end is connected to the propeller 2, is used to drive the propeller 2 to rotate in the water; and a detecting mechanism is installed on the supporting frame 3 and is used to detect the number of revolutions of the propeller 2 in the circular motion. Place the installation cover 1 on the upper surface of the pool, then start the waterproof motor 4, and the power output end of the waterproof motor 4 drives the propeller 2 to rotate. As the propeller 2 rotates, it will generate forward power to push the connecting frame 5. At this time, the rotating wheel 6 rotates in the circular groove 7 under the push of the connecting frame 5. As the rotating wheel 6 rotates, the gear block 9 follows the rotation, and the gear block 9 meshes with the gear block 9 to drive the gear 10 to rotate, allowing the rotating shaft 11 to follow the rotation. Whenever the propeller 2 pushes the connecting frame 5 to make a circular motion, the rotating shaft 11 will follow the rotation, and the number of circles is recorded by the circle number detector 12, and finally the longest service life of the propeller 2 can be obtained, so that it is convenient for the staff to judge what kind of ship the propeller 2 is suitable for.

[0025] To make propeller 2 move in a circular motion, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the power mechanism includes a waterproof motor 4 arranged in the pool, the power output end of the waterproof motor 4 is connected to the propeller 2, and the propeller 2 is driven to rotate by the waterproof motor 4, so that the propeller 2 rotates in the water, thereby providing power to drive the connecting frame 5 to make a circular motion in the water, so as to facilitate the later detection. The rotating assembly includes a connecting frame 5 arranged on the outside of the waterproof motor 4 and a rotating wheel 6 arranged in the supporting frame 3, a circular groove 7 for rotating the rotating wheel 6 is opened around the inner circle of the supporting frame 3, and a plurality of balls 8 are arranged at equal intervals around the outer circle of the rotating wheel 6. As the connecting frame 5 rotates, the rotating wheel 6 is driven to rotate in the circular groove 7, and the balls 8 are abutted against the inner wall of the circular groove 7, so that the rotating wheel 6 rotates more smoothly, reduces the error of detection, and improves the accuracy. The connecting frame 5 is connected to the lower surface of the rotating wheel 6 at one end away from the waterproof motor 4, and a tooth block 9 is arranged around the inner circle of the rotating wheel 6. As the rotating wheel 6 rotates, the gear 10 is meshed with the tooth block 9 through the gear 10, driving the gear 10 to rotate. The detection mechanism includes a gear 10 meshing with the gear block 9, a shaft 11 is inserted into the gear 10, and a rotation detector 12 is connected to the top of the shaft 11. After the gear 10 rotates, the shaft 11 is driven to rotate. The rotation detector 12 can detect the number of rotations of the shaft 11, so that the staff can observe it at any time and judge the service life and service life of the propeller 2 in turn. It should be noted that the rotation detector 12 is a prior art and is not an innovative point of this technology, so it will not be repeated here. The shaft 11 is installed on the support frame 3 through a support plate 13, and the shaft 11 is supported by the support plate 13. The connecting frame 5 is an irregular arc, so that the connecting frame 5 can follow the propeller 2 to make a circular motion.

[0026] When in use, first place the installation cover 1 on the upper surface of the pool, then start the waterproof motor 4, and the power output end of the waterproof motor 4 drives the propeller 2 to rotate. As the propeller 2 rotates, it will generate forward power to push the connecting frame 5. At this time, the rotating wheel 6 rotates in the circular groove 7 under the push of the connecting frame 5. As the rotating wheel 6 rotates, the tooth block 9 follows the rotation, and the tooth block 9 meshes with the tooth block 9, driving the gear 10 to rotate, allowing the rotating shaft 11 to follow the rotation. Whenever the propeller 2 pushes the connecting frame 5 to make a circular motion, the rotating shaft 11 will follow the rotation, and the number of circles is recorded by the circle number detector 12, and finally the longest service life of the propeller 2 can be obtained.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
