Description

Technical Field

[0002] A hydropower plant is a plant that converts the potential energy and kinetic energy of water into electrical energy. Its basic production process is: water is drawn from high places in rivers or other reservoirs, and the water pressure or flow rate is used to drive the turbine to rotate, converting the gravitational potential energy and kinetic energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] Hydropower plants often generate wastewater in the process of converting mechanical energy into electrical energy. The wastewater may contain solid waste generated by construction and maintenance. When treating the wastewater, the solid waste and liquid need to be separated and treated one by one.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a wastewater drainage filtration device for a hydropower plant, by providing a rotatable drum 401 to form a barrier to prevent the accumulation of waste and blockage.

[0032] Specifically, the sedimentation component 100 includes a sedimentation tank 101; wherein wastewater and solid waste will be uniformly discharged into the sedimentation tank 101. After the filtering operation is completed, the solid waste will remain in the sedimentation tank 101, waiting for subsequent processing, and the liquid will be discharged.

[0033] The filter assembly 200 includes a bottom frame 201 disposed in the sedimentation tank 101, an isolation hole 201a extending through the outer wall of the bottom frame 201, and an output member 202 disposed in the bottom frame 201; wherein the bottom frame 201 may be circular, and the isolation hole 201a may be arc-shaped.

[0034] A pumping assembly 300 is connected to the bottom frame 201 and is used to pump out waste water in the sedimentation tank 101. The pumping assembly 300 cooperates with the pump body to pump out the waste liquid.

[0035] The dirt-blocking assembly 400 includes a drum 401 rotatably disposed on the isolation through hole 201a; wherein the cooperation of the drums 401 enables the isolation through hole 201a to form a blocking net for isolating solid waste.

[0036] The output member 202 includes a turntable 202a disposed in the bottom frame 201, and the turntable 202a and the bottom frame 201 are not on the same axis. The end surface of the turntable 202a is penetrated by a plurality of centrifugal grooves 202a-1, and each centrifugal groove 202a-1 is movably provided with a centrifugal column 202b.

[0037] In summary, when the pumping assembly 300 pumps water, the rotating disk 202a rotates, and the rotating disk 202a in the rotating state will throw out the centrifugal column 202b originally located in the centrifugal groove 202a-1 through centrifugal force, and contact the centrifugal column 202b with the rotating drum 401, so that the rotating drum 401 rotates. In this embodiment, the number of the centrifugal grooves 202a-1 is three, and when the rotating disk 202a rotates, the centrifugal column 202b will not be completely thrown out to the point where it does not contact the centrifugal groove 202a-1. Due to the centrifugal position design of the rotating disk 202a and the bottom frame 201, after the rotating disk 202a rotates a certain angle, the thrown out centrifugal column 202b will still be squeezed into the centrifugal groove 202a-1 by the inner wall of the bottom frame 201.

[0038] That is, the movement of each drum 401 is intermittent, not continuous rotation. Compared with continuous movement, the intermittent movement of the drum 401 is not continuous, thus reducing the continuous accumulation of waste on the drum, further reducing the risk of blockage caused by long-term rotation.

[0039] Example 2, reference Figures 3 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a method for driving the turntable 202a to rotate as the pumping assembly 300 pumps water.

[0040] Specifically, a connecting through hole 201b is formed through the end surface of the bottom frame 201, and the pumping assembly 300 includes a first pipe 301 connected to the connecting through hole 201b and a second pipe 302 communicating with the first pipe 301, and a water pump is arranged in the second pipe 302. Since the water pump has been fully described in the prior art, it will not be elaborated here.

[0041] The axis of the rotating disk 202a is provided with a rotating shaft 202c, and one end of the rotating shaft 202c extends into the first pipe 301 and is provided with a fan blade 202c-1. The rotating shaft 202c and the rotating disk 202a are located on the same axis. When the liquid is pumped out by the water pump, the water flow will drive the fan blade 202c-1 to rotate, which makes the rotating shaft 202c drive the rotating disk 202a to rotate.

[0042] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention, is different from the previous embodiment in that the speed of each rotation of the drum 401 is provided to further optimize its anti-blocking effect.

[0043] Specifically, the outer wall of the rotating drum 401 is provided with a plurality of protrusions 401a, a fixing ring 401b is provided in the isolation through hole 201a, and a plurality of clamping grooves 401b-1 are arranged in a circumferential array on the inner wall of the fixing ring 401b, and a clamping block 403 is movably provided in the clamping groove 401b-1. The protrusions 401a can prevent waste from adhering to the outer wall of the rotating drum 401, and the inner end surface of the isolation through hole 201a can provide support for the rotating drum 401 during rotation.

[0044] It should be noted that the fixing ring 401b is fixed.

[0045] An elastic member 401b-2 is also provided between the clamping block 403 and the clamping groove 401b-1; an output disk 404 is screwed to one end of the rotating drum 401, and the output disk 404 is located inside the fixing ring 401b, and a limiting groove 404a is provided on the outer wall of the output disk 404. The elastic member 401b-2 is a compression spring, and if the output disk 404 rotates, the output disk 404 will drive the rotating drum 401 to rotate at the same time; and there is only one limiting groove 404a.

[0046] The outer wall of the block 403 is provided with a first inclined surface 403a, and a contact ring 402 is rotatably provided in the isolation through hole 201a, and a connecting shaft 402a is screwed on the axial direction of the contact ring 402, one end of the connecting shaft 402a extends into the fixed ring 401b and is provided with a lever 402b, and a second inclined surface 402b-1 is provided on the outer wall of the lever 402b. The diameter of the contact ring 402 is slightly larger than the diameter of the rotating drum 401, and in order to further optimize the anti-blocking effect of the rotating drum 401, combined with the description of the first embodiment, when the centrifugal column 202b is rotated out by the rotating disk 202a, it preferentially contacts the contact ring 402.

[0047] The end surface of the output disk 404 is provided with a hook 404b, and the hook 404b is sleeved with a tension spring 404b-1, and the tension spring 404b-1 is connected to the lever 402b at one end away from the hook 404b. The tension spring 404b-1 cooperates with other components to achieve a certain force storage effect.

[0048] The outer wall of the contact ring 402 is provided with an anti-skid pad 402c, wherein the anti-skid pad 402c is made of rubber material and can be deformed to a certain extent, so as to increase the friction between the contact ring 402 and the centrifugal column 202b.

[0049] The outer wall of the sedimentation tank 101 is provided with a water inlet pipe 101a, and the inner end surface of the sedimentation tank 101 is provided with a sedimentation tank 101b. The water inlet pipe 101a is used to input the solid-liquid mixture into the sedimentation tank, and the sedimentation tank 101b is low-lying, which is convenient for the sedimentation of solid waste.

[0050] In summary, when the pumping assembly 300 pumps water and causes the rotating disk 202a to throw out the centrifugal column 202b, the centrifugal column 202b will contact the contact ring 402, thereby driving the lever 402b to rotate. The lever 402b in the rotating state is acted upon by the tension spring 404b-1 and pulls the output disk 404, but the output disk 404 does not rotate at this time.

[0051] Among them, the turntable 202a is eccentrically set in the bottom frame 201, and when the turntable 202a rotates, the centrifugal column 202b will be thrown out and come into contact with the contact ring 402. Once the centrifugal column 202b rotates away from the contact ring 402, the centrifugal column 202b will be squeezed by the bottom frame 201 and move into the turntable 202a.

[0052] The output disk 404 will not rotate until the lever 402b squeezes one of the blocks 403, causing the block 403 to be separated from the limiting groove 404a and retracted into the clamping groove 401b-1, and the output disk 404 will rotate at a certain angle, and so on. This makes the rotation of the output disk 404 have a certain force accumulation effect due to the cooperation of the blocks 403 and the tension spring 404b-1, which will make the rotating drum 401 rotate faster at each rotation, thereby further optimizing its anti-blocking effect.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. 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, which should all be included in the scope of the claims of the present invention.
