When the support plate 51 is installed on the hull 1, the support plate 51 is controlled to rise so that the through hole 515 of the support plate 51 is arranged opposite to the connecting column 53, and the first screw rod 532 is threadedly penetrated through the first threaded hole 513. By rotating the first screw rod 532, the support plate 51 can be controlled to rise until the support plate 51 is completely sleeved on the connecting column 53, so that the support plate 51 is stably installed relative to the hull 1.

[0052] like Fig.10 , Fig.11 As shown, in order to control the rising of the support plate 51 so that the end of the support plate 51 is sleeved on the connecting column 53, a through hole 512 is provided in the vertical section of the support plate 51, and an internal threaded tube 511 is fixedly provided on the top of the vertical section of the support plate 51, and a threaded column 521 is penetrated by a bearing connection at the first top tube 52, and the threaded column 521 is threadedly penetrated by the internal threaded tube 511, and the bottom of the threaded column 521 extends into the through hole 512, therefore, by rotating the threaded column 521, the internal threaded tube 511 can be controlled to drive the support plate 51 to rise.

[0053] In addition, the top of the threaded column 521 is connected to the first top tube 52 through a bearing, and the support plate 51 is driven to rotate by rotating the threaded column 521 to adjust the position of the propeller 2, which is convenient for driving the propeller 2 to rise and fall, and for installing and disassembling the propeller 2 or repairing and cleaning the propeller 2. In order to ensure the stable installation of the threaded column 521, a clamping plate 522 is fixedly provided on the side of the first top tube 52, and a second threaded hole 523 is provided on the clamping plate 522. Specifically, a circular groove is provided on the clamping plate 522, and the second threaded hole 523 is arranged below the circular groove. A fastening bolt 524 is threadedly penetrated at the second threaded hole 523, that is, the top of the fastening bolt 524 is immersed in the circular groove.

[0054] At the same time, a card slot 12 is arranged on the top of the hull 1, and the card plate 522 is installed in the card slot 12. Therefore, the first top pipe 52 is connected to the hull 1 with the cooperation of the card plate 522 and the card slot 12. A threaded groove is arranged on the bottom surface of the card slot 12, and the bottom thread of the fastening bolt 524 is inserted into the threaded groove. Therefore, the card plate 522 is stably connected to the hull 1 under the action of the fastening bolt 524.

The top of the second screw rod 61 is connected through the second top pipe 62 through a bearing, and the bottom of the second screw rod 61 can be threadedly inserted into the second threaded hole 523, and then the second screw rod 61 is used to control the lifting of the clamping plate 522, which provides convenience for slowly controlling the lifting of the propeller 2.

[0056] The top of the diagonal support plate 63 is hingedly connected to the second top tube 62, and the lower end is hingedly connected to be provided with a bottom plate 632, and a plug plate 651 is fixedly provided on the side of the bottom plate 632, and the plug plate 651 is arranged as a deformable U-shaped structure, and the end of the plug plate 651 is arranged as a chamfer. In addition, a slot 11 is arranged on the hull 1, and the width of the end of the plug plate 651 is slightly larger than the width of the slot 11. Therefore, the plug plate 651 can be deformed and inserted into the slot 11. With the cooperation of the plug plate 651 and the slot 11, the bottom plate 632 is stably installed on the hull 1. Therefore, the bottom of the diagonal support plate 63 is placed still relative to the hull 1.

[0057] In order to ensure that the diagonal support plate 63 is stably tilted, the telescopic rod group 64 includes a first tube body 641, a second tube body 642, a third tube body 644 and a third screw 643. A connecting rod is provided at the top of the first tube body 641, and a plurality of connecting holes 631 are provided on the side wall of the diagonal support plate 63. The connecting rod is provided through the connecting hole 631, and the connecting rod can be disassembled as needed, so as to facilitate the change of the connection position between the diagonal support plate 63 and the first tube body 641 as needed. The second tube body 642 is fixedly provided with the top of the third tube body 644, and the upper end is inserted into the first tube body 641 to realize the movable connection between the third tube body 644 and the first tube body 641. The top of the third screw 643 is connected to the first tube body 641 through a bearing, and the lower end thread is provided through the third tube body 644. Therefore, by rotating the third screw 643, the relative movement of the first tube body 641 and the third tube body 644 can be controlled, thereby adjusting the length of the telescopic rod group 64 to achieve stable placement of the diagonal support plate 63. In addition, the bottom of the telescopic rod group 64 is inserted into the slot 11 of the hull 1 to achieve stable installation of the telescopic rod group 64 relative to the hull 1.

The top of the adjusting screw rod 622 is connected to the second top tube 62 through a bearing connection. A lifting frame 623 is arranged through the two vertical plates 621, and the adjusting screw rod 622 is threadedly arranged through the lifting frame 623. Therefore, when the adjusting screw rod 622 is rotated, the lifting frame 623 can be controlled to rise and fall and adjust the position. In addition, a stopper rod 624 is fixedly arranged on the side of the lifting frame 623, and the stopper rod 624 contacts the side wall of the diagonal support plate 63. Therefore, the second screw rod 61 and the diagonal support plate 63 can remain relatively still, so that the lifting and lowering of the clamping plate 522 can be controlled by rotating the second screw rod 61.

Therefore, with the cooperation of the clamping plate 415 and the connecting plate 413, the annular column 42 is stably installed in the space formed by the annular frame 41 and the inner ring plate 412, so as to filter the water flowing to the propeller 2 and prevent impurities from entering the propeller 2 with the water flow. In addition, the annular column 42 can be disassembled and replaced by disassembling the clamping plate 415. A hoop 43 is provided on the top of the annular frame 41, and the hoop 43 is sleeved on the second connecting seat 31. At the same time, the inner side surface of the inner ring plate 412 is provided as a curved groove 411, and is sleeved on the protruding part of the propeller 2, so as to achieve stable installation of the filter element 4.
