[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a propeller-type water turbine oil receiver.

[0027] The utility model provides Figure 1-3 The illustrated propeller turbine oil receiver comprises an oil receiver body 1 and an oil guide pipe 2 and an oil inlet pipe 3 which are connected to the upper end of the oil receiver body 1. An oil filter pipe 4 is connected between the oil guide pipe 2 and the oil inlet pipe 3. Both ends of the oil filter pipe 4 are connected to the oil guide pipe 2 and the oil inlet pipe 3 through mounting flanges 17. An oil filter net 5 is fixedly provided on the inner wall of the oil filter pipe 4. The oil filter net 5 is inclined. A cross bar 6 is fixedly provided on the middle end of the inner wall of the oil filter pipe 4. A rotating block 7 is rotatably sleeved on the rod wall of the cross bar 6. A scraper 8 is provided on the upper end of the rotating block 7 through an elastic mechanism. The scraper 8 contacts and cooperates with the bottom of the oil filter net 5.

[0028] A push plate 9 is fixedly provided at the lower end of the rotating block 7, and an oil driving mechanism is provided at the lower end of the push plate 9. The oil driving mechanism includes a rotating rod 12, which is rotatably arranged at the lower end of the inner wall of the oil filter pipe 4, and a rod wall fixed sleeve of the rotating rod 12 is provided with an impeller 13, and a rod wall fixed sleeve of the rotating rod 12 is provided with a rotating plate 14, and a push rod 15 is fixedly provided on the outer wall of the rotating plate 14, and the push rod 15 is in contact with the push plate 9, and the push rod 15 is arranged in an L shape, and a torsion spring 16 is provided on the rod wall sleeve of the cross bar 6, and the two ends of the torsion spring 16 are respectively fixedly connected to the cross bar 6 and the rotating block 7.

[0029] When the oil receiver is in use, the oil receiver passes the oil into the oil guide pipe 2 through the operating oil pipe, and filters the impurities in the oil through the oil filter screen 5 inside the oil filter pipe 4, so that the clean oil enters the oil inlet pipe 3 and passes into the other components inside the turbine. Since the oil filter screen 5 is arranged at an angle, some impurities can fall away from the oil filter screen 5 by the dripping and self-weight of the oil. At the same time, when the oil enters the oil filter pipe 4 through the oil guide pipe 2, the oil has a large thrust and drives the impeller 13 to rotate. At this time, the impeller 13 drives the rotating rod 12 and the rotating plate 14 to rotate, and the push rod 15 begins to contact the push plate 9. At this time, the push plate 9 drives the rotating block 7 to rotate around the cross bar 6 and twists the torsion spring 16. While the rotating block 7 rotates, the scraper 8 follows the rotating block 7 to clean the impurities on the surface of the oil filter screen 5 to ensure that the oil filter screen 5 is not blocked, so that the oil can flow continuously and stably, thereby improving the stability of the oil receiver.

[0030] In order to be able to repeatedly clean the impurities on the surface of the oil filter 5, Figure 3 As shown, the elastic mechanism includes a telescopic rod 10, the two ends of which are fixedly connected to the scraper 8 and the rotating block 7 respectively, and a spring 11 is sleeved on the sleeve end of the telescopic rod 10, and the two ends of the spring 11 are fixedly connected to the telescopic rod 10 and the scraper 8 respectively.

[0031] When the rotating block 7 drives the scraper 8 to rotate, the elastic expansion and contraction of the spring 11 and the telescopic rod 10 can make the side of the scraper 8 always contact the surface of the oil filter 5, so that impurities on the surface of the oil filter 5 can be fully cleaned.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
