[0029] Please refer to Figures 1-3 As shown, a sewage cleaning device capable of collecting and cleaning floating objects on the water surface provided by the embodiment of the present application includes:

[0030] A grab frame 1;

[0031] A sewage deflecting mechanism, the sewage deflecting mechanism includes a support cross bar 21 that is horizontally arranged and rotatably connected to the grab frame 1, and a plurality of sewage deflecting teeth 22 for collecting floating objects on the water surface are provided on the support cross bar 21;

[0032] Bucket flaps, the bucket flaps include a first bucket flap 31 and a second bucket flap 32, the first bucket flap 31 and the second bucket flap 32 are located below the sewage deflecting teeth 22 and form a closed bucket cavity for collecting floating objects on the water surface;

[0033] Driving members, the driving members include a first driving member 41, a second driving member 42 and a third driving member 43 fixedly connected to the grab frame 1. The first driving member 41 is connected to the support cross bar 21 for driving the support cross bar 21 to rotate, and the second driving member 42 and the third driving member 43 are respectively connected to the first bucket flap 31 and the second bucket flap 32 for driving the first bucket flap 31 and the second bucket flap 32 to move towards or away from each other, so as to realize the opening and closing of the closed bucket cavity.

[0034] In the sewage cleaning device capable of collecting and cleaning floating objects on the water surface provided by the embodiment of the present application, the sewage deflecting mechanism can be located on the upstream side or the downstream side of the water flow relative to the grab frame 1. The closed bucket cavity refers to a cavity with an open upper end formed after the first bucket flap 31 and the second bucket flap 32 move towards each other.

[0035] During operation, first lower the grab frame 1 until the pollution scraping teeth 22 are above the floating objects on the water surface, and then drive the support crossbar 21 to rotate outward relative to the grab frame 1 based on the first driving member 41 to realize the opening action of the pollution scraping teeth 22. Then continue to lower the grab frame 1 until the pollution scraping teeth 22 contact the floating objects on the water surface, and control the first driving member 41 to drive the support crossbar 21 to rotate inward relative to the grab frame 1 to realize the closing action of the pollution scraping teeth 22. At this time, the multiple pollution scraping teeth 22 on the support crossbar 21 can collect the floating objects on the water surface into the closed hopper cavity formed by the first hopper flap 31 and the second hopper flap 32. Therefore, by controlling the opening and closing actions of the pollution scraping teeth 22 with the first driving member 41, the floating objects on the water surface can be collected into the closed hopper cavity formed by the first hopper flap 31 and the second hopper flap 32, thus realizing the collection and cleaning of the floating objects on the water surface. This device can effectively reduce the environmental pollution and operation risks of the power station, and at the same time improve the power generation efficiency of the power station. It can be widely applied to the transformation of the pollution scraping grab of the power station, which is beneficial to saving project costs.

[0036] It should be noted that in the above embodiment, the multiple pollution scraping teeth 22 are composed of multiple short plates arranged horizontally and vertically in a crosswise manner; the first driving member 41, the second driving member 42, and the third driving member 43 are all driving oil cylinders. In other embodiments, the driving oil cylinders can be replaced with electric push rods.

[0037] In some embodiments, the multiple pollution scraping teeth 22 are evenly arranged on the lower side surface of the support crossbar 21.

[0038] In the above embodiment, the multiple pollution scraping teeth 22 are evenly arranged on the lower side surface of the support crossbar 21. In other embodiments, the multiple pollution scraping teeth 22 can be evenly arranged on the upper side surface of the support crossbar 21, or the multiple pollution scraping teeth 22 can be evenly arranged on both the upper side surface and the lower side surface of the support crossbar 21 at the same time, as long as it is ensured that the floating objects on the water surface can be collected into the closed hopper cavity formed by the first hopper flap 31 and the second hopper flap 32 during the opening and closing process of the multiple pollution scraping teeth 22.

[0039] In some embodiments, a vertical support rod 23 is further included. The vertical support rod 23 is perpendicularly and fixedly connected to the support crossbar 21, and the side of the vertical support rod 23 away from the support crossbar 21 is rotatably connected to the grab frame 1.

[0040] In the above embodiment, the support crossbar 21 is perpendicularly and fixedly connected to the vertical support rod 23, so that the support crossbar 21 can be rotatably connected to the grab frame 1 through the vertical support rod 23.

[0041] In some embodiments, a support diagonal rod 24 is further included. One end of the support diagonal rod 24 is fixedly connected to the support crossbar 21, and the other end of the support diagonal rod 24 is fixedly connected to the vertical support rod 23.

[0042] In the above-described embodiments, the two end portions of the support diagonal rod 24 are respectively fixedly connected to the support cross rod 21 and the vertical support rod 23 to form a right triangle, which can effectively ensure the overall stability of the sewage cleaning mechanism.

[0043] In some embodiments, it further includes a first fixing block 25 and a second fixing block 26 fixed on the grab frame 1. Through holes (not shown in the figure) are provided at one ends of the first fixing block 25 and the second fixing block 26 away from the grab frame 1. Short shafts (not shown in the figure) that are rotationally connected to match the through holes are fixedly connected to the upper and lower ends of the vertical support rod 23.

[0044] In the above-described embodiments, through the rotational connection between the through hole and the short shaft, the vertical support rod 23 can rotate along the first fixing block 25 and the second fixing block 26. The vertical support rod 23 can drive the horizontal support rod 21 and the sewage cleaning teeth 22 to rotate horizontally, thereby realizing the opening and closing actions of the sewage cleaning teeth 22.

[0045] In some embodiments, it further includes a rotating connecting rod 27 connected to the first driving member 41. One end of the rotating connecting rod 27 is connected to the support cross rod 21, and the other end of the rotating connecting rod 27 is movably hinged to the grab frame 1.

[0046] In the above-described embodiments, since one end of the rotating connecting rod 27 is movably hinged to the grab frame 1, when the first driving member 41 drives the rotating connecting rod 27, the rotating connecting rod 27 can drive the support cross rod 21 to rotate horizontally.

[0047] In some embodiments, it further includes a guiding mechanism. The guiding mechanism includes a guiding groove 8 and a guiding rod (not shown in the figure). The guiding groove 8 is located on the grab frame 1, and the guiding rod is fixed on an external device and matches the guiding groove 8 to realize the movement guiding of the grab frame 1.

[0048] In the above-described embodiments, when it is necessary to clean and collect the floating objects on the water surface, the grab frame 1 moves downward along the guiding rod through the matching of the guiding rod and the guiding groove 8 until the sewage cleaning teeth 22 contact the upper part of the floating objects on the water surface. Operate the first driving member 41 to drive the rotating connecting rod 27 to drive the sewage cleaning teeth 22 to rotate outward of the grab frame 1 to realize the opening action of the sewage cleaning teeth 22. Continue to lower the grab frame 1. When the sewage cleaning teeth 22 contact the floating objects on the water surface, operate the first driving member 41 to drive the rotating connecting rod 27 to drive the sewage cleaning teeth 22 to rotate inward of the grab frame 2 to realize the closing action of the sewage cleaning teeth 22. Therefore, through the opening and closing actions of the sewage cleaning teeth 22, the floating objects on the water surface can be collected in the closed cavity formed by the first bucket flap 31 and the second bucket flap 32. The matching setting of the guiding rod and the guiding groove 8 plays a guiding role in the lifting movement of the grab frame 1.

[0049] In some embodiments, a hydraulic pump station 6 is fixedly connected to the grab frame 1, and the hydraulic pump station 6 is respectively connected to a first driving member 41, a second driving member 42, and a third driving member 43.

[0050] In the above embodiments, by providing the hydraulic pump station 6 on the grab frame 1, the driving power of the first driving member 41, the second driving member 42, and the third driving member 43 is ensured based on the hydraulic pump station 6.

[0051] In some embodiments, a first connecting rod 7 and a second connecting rod 8 are further included. One end of the first connecting rod 7 is movably connected to the first bucket flap 31, and the other end of the first connecting rod 7 is movably connected to the grab frame 1. One end of the second connecting rod 8 is movably connected to the second bucket flap 32, and the other end of the second connecting rod 8 is movably connected to the grab frame 1.

[0052] In the above embodiments, by providing the first connecting rod 7 and the second connecting rod 8, the movement ranges of the first bucket flap 31 and the second bucket flap 32 during the process of the second driving member 42 and the third driving member 43 driving the first bucket flap 31 and the second bucket flap 32 to move towards or away from each other are restricted, providing guarantee for the movement stability of the first bucket flap 31 and the second bucket flap 32.
