DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0020] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person 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 this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0021] Reference Figure 1~Figure 4 , this embodiment provides a debris separation mechanism, including, The main body component 1 includes a first filter component 11, a second filter component 12 and a cleaning component 13, wherein the second filter component 12 is connected to the outside of the first filter component 11, and the cleaning component 13 is connected to the bottom end of the second filter component 12; Auxiliary component 2, auxiliary component 2 is used to improve the effect of the second filtering component 12 and the cleaning component 13.

[0022] Before entering the water inlet pipe, the water will pass through the first filter component 11 and the second filter component 12. The first filter component 11 is mainly used to filter large debris such as wood blocks and branches in the water, and the second filter component 12 is mainly used to filter smaller debris such as sand and gravel.

[0023] The filtered sand and gravel will be deposited inside the cleaning component 13. Under the natural flushing of the water flow, the sand and gravel will be gradually dispersed by the water flow, thereby preventing the sand and gravel from accumulating.

[0024] The auxiliary component 2 can prevent sand and gravel from flowing back or prevent large debris such as wood blocks and branches from clogging the cleaning component 13.

[0025] As an embodiment provided in this application, Figure 1~Figure 3 The first filter assembly 11 includes a first filter plate 111 and a filter hole 112 opened inside the first filter plate 111; The first filter plate 111 is configured to be arc-shaped.

[0026] When water flows through the filter holes 112, large debris such as wood blocks and branches will be blocked on the outside by the first filter plate 111. Since the first filter plate 111 is arranged in an arc shape, large debris such as wood blocks and branches will flow through the first filter plate 111 from both sides under the guidance of the arc surface on the outside of the first filter plate 111, thereby preventing large debris such as wood blocks and branches from always blocking the outside of the first filter plate 111 and affecting water intake. In addition, since large debris such as wood blocks and branches will flow through the first filter plate 111 from both sides, the situation in which large debris such as wood blocks and branches sink and clog the outside of the cleaning component 13 is reduced.

[0027] As an embodiment provided in this application, Figure 1~Figure 4 The second filter assembly 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.

[0028] After the water flows through the first filter plate 111 , the water flow velocity is reduced due to the obstruction of the water flow by the first filter plate 111 , so that the sand and gravel in the water flow can be better settled.

[0029] When the water flows through the second filter plate 122, the sand and gravel will be filtered out and gradually settle at the bottom of the box 121. Driven by the water flow, the settled sand and gravel will gradually move to the slag discharge port 124, so that the sand and gravel 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 to prevent excessive deposition of sand and gravel inside the box 121, resulting in clogging of the second filter plate 122.

[0030] As an embodiment provided in this application, Figure 1~Figure 3 The cleaning assembly 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 on the outside of the support plate 131; There are two support plates 131 , and the two support plates 131 , the box body 121 and the bottom plate 132 together form a cleaning channel 133 .

[0031] After the sand and gravel are deposited inside the cleaning channel 133 , the water flow will continuously wash away the sand and gravel when passing through the cleaning channel 133 , so that the deposited sand and gravel are taken away by the water flow, thereby preventing too much sand and gravel from being deposited inside the cleaning channel 133 .

[0032] In addition, when the water flows through the cleaning channel 133, the water flow above the inside of the cleaning channel 133 will flow to the bottom of the cleaning channel 133 under the guidance of the slope block 123, so as to more effectively flush the sand and gravel deposited at the bottom of the cleaning channel 133. Moreover, since the water flow passing through the cleaning channel 133 is not filtered, sand and gravel may be mixed in the water flow. When the sand and gravel follow the water flow through the cleaning channel 133, part of the sand and gravel will be blocked by the slope block 123, thereby preventing the water flow mixed with sand and gravel from directly impacting the bottom of the second filter plate 122, so as to reduce the situation where the sand and gravel follow the water flow under the guidance of the bottom of the second filter plate 122 and flow back into the box body 121.

[0033] As an embodiment provided in this application, Figure 5~Figure 10 , the auxiliary component 2 is a first auxiliary component 21 or a second auxiliary component 22 or a third auxiliary component 23; The first auxiliary component 21 is disposed inside the box body 121 , the second auxiliary component 22 is disposed inside the bottom plate 132 , and the third auxiliary component 23 is disposed inside the cleaning channel 133 .

[0034] During the flood season of a river, the water flow rate will increase, and the auxiliary component 2 is used to improve the effect of the second filtering component 12 and the cleaning component 13 during the flood season of the river.

[0035] As an embodiment provided in this application, Figure 5 and Figure 6The 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 .

[0036] During the flood season of the river, the water flow velocity increases, and the water flowing through the cleaning channel 133 is likely to carry more sand and gravel, so it is more likely for sand and gravel to flow back into the box body 121 through the slag discharge port 124.

[0037] When the water flow rate increases, since the second filter plate 122 is hinged to the box body 121, and an arc groove 211 is provided on the top of the box body 121 for the second filter plate 122 to rotate, the water flow will push the second filter plate 122 to rotate when passing through the second filter plate 122. At this time, the top of the second filter plate 122 is in contact with the blocking surface 212, and the bottom of the second filter plate 122 is in contact with the slope block 123, so the slag discharge port 124 will be blocked, thereby effectively preventing sand and gravel from flowing back.

[0038] In addition, when the water flow velocity increases, the water flow passing through the cleaning channel 133 can more easily disperse the sand and stones deposited inside the cleaning channel 133.

[0039] However, since the slag discharge port 124 is blocked, the sand and gravel in the box body 121 cannot be discharged, so it is necessary to increase the maintenance frequency of the staff during the flood season.

[0040] In addition, as the water flow velocity increases, it is easier for the water flow to carry large debris such as wood blocks and branches into the cleaning channel 133, causing the cleaning channel 133 to be blocked.

[0041] As an embodiment provided in this application, 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 .

[0042] During the flood season of the river, the water flow velocity increases, and under the guidance of the inclined groove 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.

[0043] At this time, since there is no water flow passing through the cleaning channel 133, it is possible to effectively prevent sand and stones from flowing back into the box body 121 along with the turbulent water flow.

[0044] In addition, since the cleaning channel 133 is blocked, it can also effectively prevent the turbulent water flow from driving large debris such as wood blocks and branches to block the cleaning channel 133.

[0045] In addition, since the slag discharge port 124 is not blocked, the sand and gravel inside the box body 121 can normally pass through the slag discharge port 124 and enter the cleaning channel 133.

[0046] However, since the cleaning channel 133 is blocked, the sand and gravel deposited inside the cleaning channel 133 cannot be dispersed by the water flow, resulting in the sand and gravel being deposited inside the cleaning channel 133, requiring the staff to increase the maintenance frequency.

[0047] As an embodiment provided in this application, Fig. 9 and Fig.10 The third auxiliary component 23 includes a baffle 231 fixedly connected to the inside of the cleaning channel 133 , and a filter tank 232 opened inside the baffle 231 .

[0048] During the flood season of the river, the water flow velocity increases, and the water flows through the filter tank 232 inside the baffle 231 and enters the cleaning channel 133.

[0049] When the water flow is blocked by the baffle 231 and enters the cleaning channel 133 , the flow rate will be reduced, thereby reducing the situation where sand and stones flow back into the box body 121 to a certain extent.

[0050] In addition, even if the water flow rate is reduced, it will still have a certain degree of dispersing effect on the sand and gravel deposited inside the cleaning channel 133.

[0051] Since the slag discharge port 124 is not blocked, the sand and gravel inside the box body 121 can normally pass through the slag discharge port 124 and enter the cleaning channel 133 .

[0052] Moreover, large debris such as wood blocks and branches will also be blocked by the baffle 231 , thereby preventing the large debris such as wood blocks and branches from clogging the cleaning channel 133 .

[0053] Reference Figure 1 , Figure 3 and Figure 4 , this embodiment provides a water inlet device, including a debris separation mechanism, and also includes a transition plate 31 bolted to the outside of the box body 121, and a connecting component 32 connected to the outside of the transition plate 31; The connecting component 32 is used to provide a water inlet channel.

[0054] The connecting component 32 includes a connecting plate 321 bolted to the outside of the transition plate 31 , and a water inlet pipe 322 adapted to be installed on the outside of the connecting plate 321 .

[0055] The filtered water will enter the water inlet pipe 322 through the transition plate 31 and the connecting plate 321, and then be transported to the hydroelectric power station unit. The impurity content of the filtered water is greatly reduced, which can effectively improve the service life of the hydroelectric power station unit.

[0056] 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 without departing from the scope of the present invention.
