Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy, in particular to a front-mounted floating object cleaning device for a hydropower station. Background Art

[0002] At present, floating interceptors are widely used at the front end of the water inlet of a hydropower station to intercept pollutants floating on the water surface and prevent them from entering the turbine generator set and affecting power generation. However, most floating interceptors are set in front of the water inlet and adopt a curved structure. The floating interceptors are prone to form a depression toward the downstream under the action of the water flow. Floating objects are easy to gather in the depression and are difficult to clean. After a large number of floating objects gather, some floating objects jump over the floating interceptors and flow downstream, affecting the power generation of the hydropower station. The long-term accumulation of floating objects in front of the floating interceptors will have a great impact on the power generation of the hydropower station, and will also form suspended matter to pollute the water quality. Therefore, there is an urgent need for a device to clean up floating objects in front of the floating interceptors. Utility Model Content

In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0034] See also Figure 1-Figure 4 The utility model of the front-mounted floating object cleaning device of the hydropower station includes an active cleaning device 2, which includes a bracket 21 vertically arranged on the floating barrier pier 1, and a mounting frame 22 is arranged on the bracket 21, and the mounting frame 22 extends toward the upstream of the river. A track 23 is arranged between the mounting frames 22 on the two floating barrier piers 1, and a self-propelled device 24 adapted thereto is arranged on the track 23, and the self-propelled device 24 can move back and forth along the track 23, and a processing device 25 for extending into the water to process floating objects is arranged on the self-propelled device 24.

[0035] The processing device 25 includes a cleaning rake 252, which is installed at the bottom of the self-propelled device 24 through a lifting component 251. After extending into the water surface through the lifting component 251, the self-propelled device 24 moves on the track 23 to drive the floating objects away from the floating intercepting row 3.

[0036] It also includes an auxiliary cleaning device 4, which includes an intercepting net 45 installed between the two drift-blocking piers 1. The length of the intercepting net 45 is greater than the drift-blocking row 3 set between the two drift-blocking piers 1. Both ends of the intercepting net 45 are provided with floating platforms 41. The floating platform 41 is set on the inner side of the drift-blocking row pier 1, and the floating platform 41 is slidably connected to the drift-blocking row pier 1 through a slide rail 5. A winding component is provided on the floating platform 41.

[0037] The winding assembly includes a winding drum 43 for winding up the interception net 45 . The winding drum 43 is installed on the side of the floating platform 41 through a mounting member 42 . A winding motor 44 for driving the winding drum 43 is provided on one of the mounting members 42 .

[0038] The bottom of the winding drum 43 exceeds the bottom of the floating platform 41 , the width of the interception net 45 is matched with the length of the winding drum 43 , and both ends of the interception net 45 are vertically arranged on the sides of the two winding drums 43 .

[0039] By setting up the floating platform 41, both ends of the interception net 45 can be raised and lowered following the river water level, wherein the bottom of the winding drum 43 exceeds the bottom of the floating platform 41, that is, when the auxiliary cleaning device 4 is raised and lowered in the water, the winding drum 43 can carry the interception net 45 and keep it inserted in the water; and by the connection method of the interception net 45 on the winding drum 43, it can be ensured that when the interception net 45 is in a stretched state, it is partially located in the water and partially located on the water surface, thereby effectively intercepting floating objects.

[0040] The uppermost intercepting net 45 is provided with a connecting component 6 which can be connected to the floating arresting row 3. Through the setting of the connecting component 6, the intercepting net 45 can float on the water surface following the floating arresting row 3.

[0041] By setting the connecting component 6, the intercepting net 45 can be suspended in the water through the floating barrier row 3.

[0042] The side of the winding drum 43 close to the upstream of the river protrudes from the edge of the floating intercepting row pier 1 close to the upstream. When the winding drum 43 does not protrude from the floating intercepting row pier 1, the stretched floating intercepting row pier 3 will form an angle with the floating intercepting row pier 1, thereby affecting the floating objects being cleaned by the active cleaning device 2. The design of the side of the winding drum 43 close to the upstream of the river protruding from the edge of the floating intercepting row pier 1 close to the upstream ensures that when the intercepting net 45 is stretched between the two winding drums 43 and then protrudes from the floating intercepting row pier 1, the floating objects are effectively moved out from between the two floating intercepting row piers 1 under the traction of the intercepting net 45, so that the cleaning effect is better and the occurrence of blind spots in floating object cleaning is eliminated.

[0043] In this embodiment, the connecting member 6 may be a rope or chain that is manually fastened or tied, and the lifting member 251 may be a winch.

[0044] This embodiment, when used:

[0045] The processing assembly 25 in the main cleaning device 2 makes the lifting component 251 carry the cleaning rake 252 and descend into the water, and then the cleaning rake 252 drives the floating objects to move by the self-propelled device 24 moving on the track 23, so that the floating objects in front of the floating intercepting row 3 can be cleaned. However, this cleaning method cannot clean the concave part of the floating intercepting row 3.

[0046] For cleaning the floating objects in the depression of the drift-arresting row 3, the connecting component 6 can be manually untied, and the auxiliary cleaning device 4 can be started at the same time to cooperate with the active cleaning device 2 for processing. First, the connecting component 6 close to the winding motor 44 side needs to be untied, and the winding motor 44 is started while the connecting component 6 is untied. The starting of the winding motor 44 will cause the winding drum 43 to reel in the interception net 45, so that the interception net 45 between the winding drum 43 and the untied connecting component 6 is always kept in a straight state, and then the connecting component 6 is untied to the other side in an orderly manner, that is, the interception net 45 can be suspended in the water all the time, and changes from a state of being in contact with the depression of the drift-arresting row 3 to a straight state, thereby effectively driving the floating objects out of the depression, and then the main cleaning device 2 is started to clean the floating objects.

[0047] Embodiment 2:

[0048] See also Figure 5 As a further improvement of the first embodiment, the difference from the first embodiment is that the processing device 25 further includes a translation component 253 for moving the cleaning rake 252 laterally. The translation component 253 is installed on the self-propelled device 24, and moves the cleaning rake 252 by carrying the lifting component 251;

[0049] In this embodiment, the translation component 253 may be an electric telescopic rod, and the lifting component 251 may be a winch.

[0050] When in use, the cleaning rake 252 can be moved toward the depression of the drift-arresting row 3 by carrying the lifting component 251 with the translation component 253. When the cleaning rake 252 moves close to the drift-arresting row 3, the lifting component 251 is started to lower the cleaning rake 252 into the water, and then the translation component 253 is started. The activation of the translation component 253 can allow the cleaning rake 252 to carry the floating objects in the depression and move outward, so that the floating objects in the depression of the drift-arresting row 3 can be preliminarily cleaned. Reducing the floating objects in the depression of the drift-arresting row 3 can reduce the cleaning difficulty of the auxiliary cleaning device 4, and avoid too many floating objects in the depression of the drift-arresting row 3, which makes it difficult for the winding drum 43 to wind up the intercepting net 45.

[0051] Embodiment three:

[0052] See also Figure 6-Figure 7 As a further improvement of the second embodiment, the difference from the second embodiment is that the connecting component 6 includes a plurality of mounting blocks 63 installed with gaps on the drift-blocking row 3, and a docking block 61 installed on the intercepting net 45; the docking block 61 is provided with a card block 62 adapted to the card slot 64.

[0053] Specifically, the card slot 64 is arranged toward the upstream of the river.

[0054] The lifting component 251 includes a lifting frame 2511 fixedly connected to the translation component 253. A lifting motor 2513 and a lifting rack 2512 are provided inside the lifting frame 2511. The lifting rack 2512 is vertically slidably connected to the inner wall of the lifting frame 2511. A gear meshing with the lifting rack 2512 is provided on the output shaft of the lifting motor 2513. The cleaning rake 252 is fixedly connected to the bottom of the lifting frame 2511.

[0055] When this embodiment is used, there is no need to manually control the connecting member 6. When the connecting member 6 is used, the block 62 on the docking block 61 is engaged with the slot 64 on the mounting block 63, that is, after the interception net 45 is stretched straight by force, the block 62 will automatically be disengaged from the slot 64, so there is no need to manually untie the connecting member 6.

[0056] After use, the intercepting net 45 can be moved close to the drift-blocking row 3 by inserting the cleaning rake 252 into the water and driven by the translation component 253. When the intercepting net 45 is close to the drift-blocking row 3, the card block 62 will be stuck in the card slot 64, thereby eliminating the need to manually connect the intercepting net 45 and the drift-blocking row 3.

[0057] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
