[0034] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the detailed implementation manners and the accompanying drawings.

[0035] The terms used in the present invention are those general terms that are currently widely used in the art in consideration of the functions of the present invention. However, these terms may vary according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be construed as simple names, but rather based on the meanings of the terms and the overall description of the present invention.

[0036] Referring to Figures 1 to 4 , this embodiment provides a sundry separation mechanism, including

[0037] a main body member 1, the main body member 1 includes a first filtering component 11, a second filtering component 12 and a cleaning component 13, the second filtering component 12 is connected to the outside of the first filtering component 11, and the cleaning component 13 is connected to the bottom end of the second filtering component 12;

[0038] an auxiliary member 2, the auxiliary member 2 is used to improve the effects of the second filtering component 12 and the cleaning component 13.

[0039] Before the water flow enters the water inlet pipe, it will successively pass through the first filtering component 11 and the second filtering component 12. The first filtering component 11 is mainly used to filter large sundries such as wooden blocks and branches in the water flow, and the second filtering component 12 is mainly used to filter smaller sundries such as sand and gravel.

[0040] The filtered sand and gravel will be deposited inside the cleaning component 13. Under the natural scouring of the water flow, the sand and gravel will gradually be washed away by the water flow, thereby preventing the accumulation of sand and gravel.

[0041] The auxiliary member 2 can prevent the backflow of sand and gravel or prevent large sundries such as wooden blocks and branches from blocking the cleaning component 13.

[0042] As an embodiment provided in the present application, as Figures 1 to 3 , the first filtering component 11 includes a first filtering plate 111 and filtering holes 112 formed inside the first filtering plate 111;

[0043] Among them, the first filtering plate 111 is set to be arc-shaped.

[0044] When the water flow passes through the filtering holes 112, large sundries such as wooden blocks and branches will be blocked outside by the first filtering plate 111. Since the first filtering plate 111 is set to be arc-shaped, the large sundries such as wooden blocks and branches will flow through both sides of the first filtering plate 111 under the guidance of the outer arc surface of the first filtering plate 111, preventing the large sundries such as wooden blocks and branches from always blocking the outside of the first filtering plate 111 and affecting water intake. In addition, since the large sundries such as wooden blocks and branches will flow through both sides of the first filtering plate 111, the situation where the large sundries such as wooden blocks and branches sink and block the outside of the cleaning component 13 is reduced.

[0045] In an embodiment provided in the present application, as Figures 1 to 4 , the second filtering component 12 includes a box body 121 bolted to the outside of the first filter plate 111, a second filter plate 122 hinged inside the box body 121, a slope block 123 fixedly connected to the bottom end of the box body 121, and a slag discharge port 124 opened inside the box body 121.

[0046] After the water flow passes through the first filter plate 111, due to the blockage of the first filter plate 111, the flow rate of the water flow will decrease, so that the sand and stones in the water flow can settle better.

[0047] When the water flow passes through the second filter plate 122, the sand and stones will be filtered out and gradually settle at the bottom of the box body 121. Driven by the water flow, the settled sand and stones will gradually move to the position of the slag discharge port 124, so that the sand and stones pass through the gap between the bottom end of the second filter plate 122 and the slope block 123 and settle inside the cleaning component 13, so as to prevent too much sand and stones from depositing inside the box body 121 and causing the blockage of the second filter plate 122.

[0048] In an embodiment provided in the present application, as Figures 1 to 3 , the cleaning component 13 includes a support plate 131 bolted to the bottom end of the box body 121, a bottom plate 132 fixedly connected to the bottom end of the support plate 131, and a cleaning channel 133 arranged outside the support plate 131;

[0049] Among them, two support plates 131 are provided, and the two support plates 131, the box body 121 and the bottom plate 132 together enclose the cleaning channel 133.

[0050] After the sand and stones are deposited inside the cleaning channel 133, when the water flow passes through the cleaning channel 133, it will continuously scour the sand and stones, so that the deposited sand and stones are carried away by the water flow to prevent too much sand and stones from depositing inside the cleaning channel 133.

[0051] In addition, when the water flow passes through the cleaning channel 133, the water flow above the cleaning channel 133 will flow downward inside the cleaning channel 133 under the guidance of the slope block 123 to more effectively scour the sand and stones deposited at the bottom of the cleaning channel 133. And since the water flow passing through the cleaning channel 133 is not filtered, there may be sand and stones mixed in the water flow. When the sand and stones follow the water flow through the cleaning channel 133, part of the sand and stones will be blocked by the slope block 123, so as to prevent the water flow mixed with sand and stones from directly impacting the bottom of the second filter plate 122, so as to reduce the situation that the sand and stones follow the water flow and pour back into the box body 121 under the guidance of the bottom of the second filter plate 122.

[0052] In an embodiment provided in the present application, as Figures 5 to 10, the auxiliary component 2 is the first auxiliary component 21, the second auxiliary component 22 or the third auxiliary component 23;

[0053] Among them, the first auxiliary component 21 is arranged inside the box body 121, the second auxiliary component 22 is arranged inside the bottom plate 132, and the third auxiliary component 23 is arranged inside the cleaning channel 133.

[0054] During the flood season of the river, the water flow velocity will increase, and the auxiliary component 2 is used to improve the effects of the second filtering component 12 and the cleaning component 13 during the flood season of the river.

[0055] As an embodiment provided in the present application, such as Figure 5 and Figure 6 , the first auxiliary component 21 includes an arc-shaped groove 211 opened inside the box body 121, and a blocking surface 212 arranged inside the arc-shaped groove 211.

[0056] During the flood season of the river, the water flow velocity increases, and the water flow passing through the cleaning channel 133 is likely to carry more sand and gravel, so it is easier for the sand and gravel to backflow into the box body 121 through the slag discharge port 124.

[0057] When the water flow velocity increases, since the second filter plate 122 is hinged to the box body 121, and the box body 121 is provided with an arc-shaped groove 211 at the top for the second filter plate 122 to rotate, when the water flow passes through the second filter plate 122, it will push the second filter plate 122 to rotate. At this time, the top of the second filter plate 122 fits with the blocking surface 212, and the bottom of the second filter plate 122 fits with the slope block 123, so the slag discharge port 124 will be blocked, thereby effectively preventing the backflow of sand and gravel.

[0058] In addition, when the water flow velocity increases, the water flow passing through the cleaning channel 133 is more likely to wash away the sand and gravel deposited inside the cleaning channel 133.

[0059] However, since the slag discharge port 124 is blocked, the sand and gravel in the box body 121 cannot be discharged either. Therefore, it is necessary to increase the maintenance frequency of the staff during the flood season.

[0060] In addition, when the water flow velocity increases, the water flow is more likely to carry large debris such as wooden blocks and branches into the cleaning channel 133, causing blockage of the cleaning channel 133.

[0061] As an embodiment provided in the present application, such as Figure 7 and Figure 8 , the second auxiliary component 22 includes an inclined groove 221 opened inside the bottom plate 132, and a rotating plate 222 hinged to the outside of the bottom plate 132.

[0062] During the flood season of the river, the flow velocity of the water increases. Under the guidance of the inclined chute 221, the water flow will push the rotating plate 222 to rotate, so that the rotating plate 222 contacts the bottom of the box body 121, thereby blocking the cleaning channel 133.

[0063] At this time, since there is no water flow passing through the inside of the cleaning channel 133, it is possible to effectively prevent the situation where sand and gravel follow the rapid water flow and backflow into the inside of the box body 121.

[0064] In addition, since the cleaning channel 133 is blocked, it is also possible to effectively prevent the situation where large debris such as wooden blocks and branches is driven by the rapid water flow to block the cleaning channel 133.

[0065] In addition, since the slag discharge port 124 is not blocked, the sand and gravel inside the box body 121 can normally enter the inside of the cleaning channel 133 through the slag discharge port 124.

[0066] However, since the cleaning channel 133 is blocked, the sand and gravel deposited inside the cleaning channel 133 cannot be washed away by the water flow, resulting in the deposition of sand and gravel inside the cleaning channel 133, which requires the staff to increase the maintenance frequency.

[0067] As an embodiment provided in the present application, as Figure 9 and Figure 10 , the third auxiliary component 23 includes a baffle 231 fixedly connected inside the cleaning channel 133 and a filter slot 232 opened inside the baffle 231.

[0068] During the flood season of the river, the flow velocity of the water increases, and the water flow will enter the inside of the cleaning channel 133 through the filter slot 232 inside the baffle 231.

[0069] Blocked by the baffle 231, the water flow will reduce its velocity when entering the cleaning channel 133, so it is possible to reduce the situation of sand and gravel backflowing into the inside of the box body 121 to a certain extent.

[0070] In addition, even if the flow velocity of the water decreases, it will also have a certain degree of effect on flushing the sand and gravel deposited inside the cleaning channel 133.

[0071] Since the slag discharge port 124 is not blocked, the sand and gravel inside the box body 121 can normally enter the inside of the cleaning channel 133 through the slag discharge port 124.

[0072] Moreover, large debris such as wooden blocks and branches will also be blocked by the baffle 231, thereby preventing the situation where large debris such as wooden blocks and branches blocks the cleaning channel 133.

[0073] Refer to Figure 1 、 Figure 3 and Figure 4, this embodiment provides a water inlet device, including a debris separation mechanism, a transition disk 31 bolted to the outside of the box body 121, and a connecting component 32 connected to the outside of the transition disk 31;

[0074] Among them, the connecting component 32 is used to provide a water inlet passage.

[0075] The connecting component 32 includes a connecting disk 321 bolted to the outside of the transition disk 31, and a water inlet pipe 322 adaptively installed on the outside of the connecting disk 321.

[0076] The filtered water flow will enter the interior of the water inlet pipe 322 through the transition disk 31 and the connecting disk 321, and then be transported to the hydropower station unit. The debris content of the filtered water flow is greatly reduced, so that the service life of the hydropower station unit can be effectively improved.

[0077] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
