[0033] Example 1

[0034] Reference Figure 1-Figure 3 , which is the first embodiment of the present utility model, provides a supporting mechanism, which includes a supporting unit 100 and an adjusting unit 200;

[0035] The support unit 100 includes a support base 101, two rotating frames 102 rotatably mounted on the support base 101, and a connecting rod 103 provided between the rotating frames 102 for connection. The support base 101 is provided with an anti-slip block 104 that supports the support base 101, ensuring a more stable placement of the support base 101. The adjustment unit 200 is mounted on the support base 101, with its output end connected to the rotating frames 102.

[0036] Furthermore, the rotating frame 102 is provided with a mounting slot 102b and a coupling slot 102a communicating with the mounting slot 102b. The ends of the connecting rod 103 are embedded in the coupling slots 102a. The connecting rod 103 includes a rod body 103a and two coupling blocks 103b, one at each end of the rod body 103a and slidably disposed within the coupling slots 102a. The coupling slots 102a and coupling blocks 103b both have T-shaped cross-sections. This T-shaped structure enhances the reliability of the connection between the connecting rod 103 and the two rotating frames 102. The mounting slots 102b facilitate the insertion of the coupling blocks 103b into the coupling slots 102a for complete installation.

[0037] Among them, the rotating frame 102 is provided with a fixing groove 102c and a connecting bolt, which is embedded in the fixing groove 102c and threadedly connected to the rod body 103a; there are multiple fixing grooves 102c, so that the connecting rod 103 can be installed in multiple positions, and the connecting bolt is inserted into the fixing groove 102c and screwed into the clamping block 103b, so that the rotating frame 102 can be fixedly connected through the connecting rod 103.

[0038] During use, the support base 101 is first placed at the sewage outlet of the hydropower station and fixed. The adjusting unit 200 is used to drive the rotating frame 102 to flip so that the rotating frame 102 is in an inclined position and the upper end is located above the receiving position. It can be adjusted according to actual use needs. By inserting the clamping block 103b into the clamping groove 102a, the two rotating frames 102 are supported by the rod body 103a, so that the rotating frame 102 is reliably fixed to avoid shaking during use.

[0039] Example 2

[0040] Reference Figure 1-Figure 3 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: the adjustment unit 200 includes a support rod 201 set on the support base 101, a moving component 202 set on the support rod 201, and a connecting rod 203 whose two ends are rotatably connected to the moving component 202 and the rotating frame 102 respectively.

[0041] Furthermore, the moving assembly 202 includes a screw rod 202a rotatably set on the support rod 201, a lifting block 202b slidably set on the support rod 201 and threadedly connected to the screw rod 202a, and a rotating handle 202c set on the screw rod 202a; the connecting rod 203 is rotatably connected to the lifting block 202b, and the rotating handle 202c can facilitate the rotation of the screw rod 202a.

[0042] The rotating handle 202c is provided with a plug-in slot 202ca having a polygonal structure, through which a polygonal wrench can be directly inserted into the plug-in slot 202ca, thereby making it convenient to adjust the tilt angle from a high position.

[0043] During use, by rotating the rotating handle 202c, the rotating handle 202c drives the screw rod 202a to rotate, and the screw rod 202a drives the lifting block 202b to move. The lifting block 202b drives the connecting rod 203 to move. Since the connecting rod 203 is rotatably connected to the rotating frame 102, it drives the rotating frame 102 to flip, thereby adjusting the tilt angle of the rotating frame 102. It can be adjusted and installed according to the actual location of the sewage outlet of the hydropower station and the depth of the water level to prevent the water from completely submerging the cleaning unit 300.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3

[0046] Reference Figure 1-Figure 5 , which is the third embodiment of the present utility model, provides an automatic cleaning device for the water inlet trash rack of a unit, including the above-mentioned support mechanism, and also includes a cleaning unit 300, including two pulleys 302 rotatably arranged at both ends of the rotating frame 102, a driving motor 301 arranged on the rotating frame 102 and drivingly connected to any one of the pulleys 302, a filter belt 303 arranged on the two pulleys 302, and a conveying assembly 304 arranged on the filter belt 303.

[0047] Among them, the conveying assembly 304 includes two fixing frames 304b, both of which are arranged on the filter belt 303, a conveying plate 304a rotatably arranged on the fixing frames 304b, and a blocking plate 304c arranged on the two fixing frames 304b and engaged with the conveying plate 304a; since the blocking plate 304c supports the conveying plate 304a on one side, the conveying plate 304a is in a relatively horizontal position when conveying dirt upward, and can convey the dirt upward. When moving to the other side of the filter belt 303, the conveying plate 304a is flipped under the influence of gravity, which can better discharge the dirt and squeeze out the dirt.

[0048] The rotating frame 102 is provided with a drain chute 102d, which can remove dirt that falls between the filter belts 303 from the side after shutdown, so as to avoid excessive accumulation of dirt in the filter belts 303.

[0049] During use, the pulley 302 is driven to rotate by the driving motor 301, the pulley 302 drives the filter belt 303 to move, and the filter belt 303 drives the conveying component 304 to move, so that the conveying component 304 drives the dirt to move upward, thereby lifting the dirt to a high place. When it passes the highest point, the dirt will be poured downward, thereby cleaning out the dirt in the water.

[0050] The remaining structures are the same as those of Example 2.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
