Description

Technical Field

[0001] The present invention relates to the technical field of floating object cleaning, and particularly relates to a reservoir floating object diversion and removal device. Background Art

[0002] Water, as the source of life, is an irreplaceable precious resource on the earth. With the acceleration of the urbanization process, a large amount of domestic garbage has poured into rivers, resulting in increasingly serious water pollution. In river-type reservoirs, the water body in the reservoir area has changed significantly due to water storage, with the flow velocity slowing down, the residence time prolonging, the backwater area increasing, and there are many bays and tributaries. This makes it extremely easy for floating objects to stay and accumulate in front of the dam, at the confluence of main and tributary rivers, backwater bays, port areas, and some waters with slow flow velocities. Looking around, the reservoir surface is piled up with mountains of garbage, and the shore is often surrounded by garbage. These garbage mainly come from the surface plant cover layer, human domestic waste, industrial waste, etc., which not only seriously damage the ecological environment but also cause great trouble to the normal operation of hydropower stations on the river.

[0003] Currently, the cleaning of water surface garbage in water conservancy reservoirs mostly relies on manual fishing, and workers use bamboo poles with nets to fish for garbage one by one. This traditional method is extremely inefficient. The fishermen not only have to spend a lot of time and energy but also are extremely prone to fatigue, and there are great risks in working on the water surface. Especially during rainstorm flood peaks, a large number of floating objects will suddenly increase rapidly. Manual fishing is inefficient, and even machine fishing operations cannot meet the suddenly increased fishing demand. Moreover, there are extremely high risks during the fishing process, and the life and property safety of fishermen are seriously threatened. Casualties caused by fishing for floating objects during flood fighting and rescue operations occur from time to time, which is extremely distressing. Those large amounts of floating objects that are not fished in time are very likely to bring inestimable losses to downstream flood control work.

[0004] In water conservancy and hydropower projects, the trash rack is an important water intake structure arranged in the front area of the dam. Its main function is to intercept floating objects to prevent them from entering the generator set or water distribution pipeline and avoid mechanical damage and pipeline blockage. In recent years, scientific research personnel have continuously explored and innovated to develop a variety of new reservoir floating object cleaning devices. For example, Chinese patent CN109440749B discloses a reservoir floating object cleaning device, which continuously conveys the floating objects in the reservoir into the floating object cleaning box, effectively reducing the intensity of manual fishing. It can clean the floating objects at different depths in the reservoir, greatly improving the cleaning efficiency and expanding the working range of the cleaning device. However, its fishing speed is far less than the flow rate of floating objects during rainstorm flood peaks, and its structure is relatively complex, occupying a large space, and is not suitable for the removal of reservoir floating objects. Summary of the Invention

[0013] In some embodiments, a plurality of blocking members extending in the width direction are provided on the water filtering slideway. Each blocking member partially blocks above the water filtering holes in the width direction and is arranged at an angle with the sliding direction of the floating objects on the water filtering slideway, and the opening of the blocking member faces the floating object transfer yard.

The height of the floating net is greater than the water depth of the reservoir at the highest water level. A plurality of split floats are provided on the upper part of the floating net and a counterweight is provided on the bottom.

[0018] In some of the embodiments, the floating object guiding mechanism further comprises a sub-floating body, one end of the sub-floating body is hinged to the floating object guiding body and the other end of the sub-floating body is attached to the inner side of the dam body.

[0027] 3. The commercial space and photovoltaic power generation device on the floating object guide body can not only guide the floating objects into the overflow dam or overflow gate to realize the automatic removal of floating objects, but also recover the investment in the reservoir floating object diversion and removal device, and promote the sustainable development of the reservoir water conservancy project.

[0049] The above solutions will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present invention and not for limiting the scope of the present invention. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0050] Embodiment 1

[0051] As Figure 1 and Figure 2As shown in the figure, it is a schematic structural diagram of Embodiment 1 of the present invention, providing a device for guiding and removing floating objects in a reservoir, including an overflow dam 107, a floating object guiding mechanism, a floating object transfer yard 110, and a water filtering slideway 109.

[0052] The overflow dam 107 is arranged on the first side in the length direction of the reservoir dam 116. On the second side of the dam 116, there is a water inlet 114 for hydropower generation. After the water in the reservoir is discharged through the water inlet 114, it is used for power generation by the hydropower system 117. The overflow dam 107 is a part of the dam 116, and its height is flush with the highest water level of the reservoir and lower than the height of the dam body of the dam 116. The hydropower system 117 is a prior art, mainly including a transformer 117a, a generator 117b, and a water turbine 117c. The energy of water is converted into mechanical energy by the water turbine 117c, the generator 117b converts the mechanical energy into electrical energy, and then it is output after passing through the transformer 117a.

[0053] The floating object guiding mechanism is arranged upstream of the water inlet 114 for hydropower generation, and is used to guide the floating objects 101 on the reservoir to the overflow dam 107. It includes a floating object guide body 104 floating on the water surface. The floating object guide body 104 is limited between the dam body and the side wall of the reservoir. The water-facing surface of the floating object guide body 104 includes a first guide surface and a second guide surface. Among them, the first guide surface has an obtuse angle α112 with the water outlet direction 111, and the second guide surface is consistent with the water flow direction. This angle α112 is greater than 90 degrees and less than 180 degrees. The larger the angle α112, the smaller the collision force generated by the floating object 101 during diversion. This angle α112 can be set as needed.

[0054] In order to prevent the floating objects 101 at the overflow dam 107 from drifting to the inlet and outlet 114, the floating object guiding mechanism further includes a floating net 106. The floating net 106 is fixed between the floating object guide body 104 and the dam body. The height of the floating net 106 is greater than the water depth at the highest water level of the reservoir. There are multiple split floating bodies at the upper part of the floating net 106 and a counterweight at the bottom, preventing the floating objects 101 on the water from passing through the floating net 106 and large underwater objects from passing through the floating net 106.

[0055] In order to prevent aquatic animals or other foreign objects from entering the vicinity of the water inlet 114, a protective net 202 is provided between the floating object guide body 104 and the bottom of the reservoir, and a protective fence 206 is arranged at the water inlet 114 to further prevent foreign objects from entering the water inlet 114 and affecting the operation of the hydropower system 117.

[0056] The floating object transfer yard 110 is arranged downstream of the overflow dam 107 and is used to store the floating objects 101 discharged through the overflow dam 107. There are water leakage holes in the floating object transfer yard 110 to avoid water accumulation. A perforated guardrail can also be set around the floating object transfer yard 110 to prevent the floating objects 101 from being washed away by strong water.

[0057] A water filtering chute 109 is provided between the overflow dam 107 and the floating object transfer yard 110. A number of water filtering holes 702 are provided on the water filtering chute 109. The floating object 101 slides down the water filtering chute 109 to the floating object transfer yard 110. When the floating object 101 slides down the water filtering chute 109, water flows through the water filtering holes 702 to the inclined dam body of the dam and converges into the river at the water outlet 118 of the hydroelectric power generation system 117 and flows downstream.

[0058] As Figure 3 and Figure 4 shown, the end face AC where the water filtering chute 109 is rigidly connected to the overflow dam 107 is lower than the lowest water level of the reservoir. The slope of the first end face AB of the water filtering chute 109 near the water inlet in the width direction is smaller than the slope of the second end face CD far from the water inlet 114 in the width direction. In this way, it is possible to prevent the floating object 101 from falling into the river below the dam 116 and converging towards the floating object transfer yard 110.

[0059] To further optimize the implementation effect of the present invention and prevent the floating object from falling into the water filtering holes 702, as Figure 5 shown, a plurality of blocking members 701 extending in the width direction are provided on the water filtering chute 109. Each blocking member 701 partially blocks above the water filtering holes 702 located in the width direction and is arranged at an angle with the sliding direction 703 of the floating object 101 on the water filtering chute 109. The opening of the blocking member 701 faces the floating object transfer yard 110. In this way, the floating object 101 will generate a jumping action during the sliding process on the water filtering chute 109 until it reaches the floating object transfer yard 110, thereby preventing it from getting stuck on the water filtering chute 109 and blocking the water filtering holes 702.

[0060] To facilitate the limiting of the floating object guide 104, a plurality of upright columns 103 are fixed to the bottom of the reservoir. The plurality of upright columns 103 extend in the vertical direction. The floating object guide 104 is sleeved on the plurality of upright columns 103. A sliding sleeve 204 through which the upright columns 103 pass is provided on the floating object guide 104, which can prevent wear between the floating object guide 104 and the upright columns 103. In this way, the position of the floating object guide 104 remains unchanged in the horizontal direction relative to the bottom of the reservoir, and the floating object guide 104 is movably connected to the bottom of the reservoir in the plumb direction; the position of the floating object guide 104 remains unchanged in the horizontal direction relative to the dam 116 or the overflow dam 107 and the water filtering chute 109; the water filtering chute 109 is rigidly connected to the overflow dam 107; the water filtering chute 109 is rigidly connected to the floating object transfer yard 110. In this example, the dimension of the cross section of the upright column 103 in the water outlet direction is larger than the dimension in the direction perpendicular to the water outlet direction. Preferably, the cross section of the upright column 103 is close to an ellipse. The upright column 103 with this shape can increase the impact resistance of the water flow and improve the strength of the structure.

[0061] In order to reduce the collision and wear between the floating object 101 and the floating object guide body 104 , a buffer block 102 is provided on the water-facing surface of the floating object guide body 104 , and the buffer block 102 and the floating object guide body 104 are connected by bolts.

[0062] The overlapping portion 108 between the water filtering slide 109 and the floating object guide 104 is greater than zero, and the floating objects 101 can also smoothly pass through the overflow dam 107 and enter the water filtering slide 110 for separation under the action of inertia, thereby completely and automatically removing the floating objects 101 in the reservoir.

[0063] Example 2

[0064] like Figure 6 and Figure 7 As shown, it is a structural schematic diagram of embodiment 2 of the present invention. The rest is the same as the embodiment, except that: the floating net 106 is replaced by a sub-floating body 302, one end of the sub-floating body 302 is hinged to the floating object guide body 104 via a hinge 301 and the other end is attached to the inner side of the dam body and covers the dry and wet dam 105. The dry and wet dam 105 refers to the inclined part of the dam 116 that is submerged and exposed during the change of the lowest water level and the highest water level.

[0065] When the water level in the reservoir changes, the sub-float 302 rotates up and down along the floating object guide body 104 and always sticks to the inner side of the dam body. The floating object guide body 104 and the sub-float 302 completely cover the water surface upstream of the water inlet 114, thereby preventing the floating object 101 from drifting to the water inlet 114.

[0066] Example 3

[0067] In the dry season, it is difficult for the water volume in the reservoir to reach the highest water level. In order to facilitate the removal of floating objects 101, an overflow gate 808 is provided on the overflow dam 107. At the same time, a first image acquisition component 113 for collecting information on the number of floating objects at the outlet of the overflow dam 107 is provided on the floating object guide 104. The overflow gate 808 and the first image acquisition component 113 are electrically connected to the controller. The controller controls the opening of the overflow gate 808 according to the data collected by the first image acquisition component 113, wherein the first image acquisition component 113 uses a camera.

[0068] The overflow gate 808 includes a first electric winch 803 fixed on the overflow dam 107, a first gate plate 806 drivingly connected to the first electric winch 803, and a sealing gasket 807 fixed to the first gate plate 806, and the sealing gasket 807 is attached to the inner wall of the overflow dam 808. The first gate plate 806 is connected to the first electric winch 803 via a first steel wire rope 804, the sealing gasket 807 is fixed to the first gate plate 806 via glue or screws, and the first image acquisition component 113 is fixed to the floating object guide 104 via bolts.

[0069] When the number of floating objects 101 collected by the first image acquisition component 113 at the overflow dam 107 exceeds the first threshold, the controller warns the duty personnel, and the first electric winch 803 lowers the first gate plate 806 to make it lower than the water surface of the reservoir (such as Figure 8 As shown in FIG. 1 , the floating objects 101 flow through the overflow dam 107 along with the water flow to the water filter slide 109, so that the floating objects 101 are separated and removed from the water. When the number of floating objects 101 at the overflow dam 107 captured by the first image acquisition component 113 is lower than the second threshold, the controller controls the first electric winch 803 to pull up the first gate plate 806 so that its top is flush with the highest water level 801 (as shown in FIG. 1 ). Figure 10 As shown), the water separation and removal of the floating object 101 is completed. It should be understood that the duty personnel can also manually terminate the warning information, manually operate the overflow process, or use other electric control hoist systems instead of electric winches and wire ropes to open and close the gate. The first threshold and the second threshold are set according to the water scheduling plan, environmental protection requirements and power production plan in the dry season. For example, the first threshold can be set to 10%-45% of the visible water area in front of the dam on the image, and the second threshold can be set to 0-0.1% of the visible water area in front of the dam on the image.

[0070] This embodiment is applicable to both dry season and wet season. Figure 9 As shown, during the process of the controller controlling the first electric winch 803 to lower the top of the first gate plate 806 to be flush with the lowest water level 802, the first gate plate 806 approaches the bottom 805 of the reservoir, and the floating objects 101 flow through the overflow dam 107 with the water flow to the water filter slide 109, so that the floating objects 101 are separated from the water, and the floating objects 101 in the reservoir are completely automatically removed. In the flood season, there is already water overflowing in front of the overflow dam 107, and there is no need to raise or lower the overflow gate 808 to separate and remove the floating objects 101 from the water. Especially during the peak of heavy rain and flood, a large amount of water automatically flows out at high speed from the overflow gate 808 stopped at the highest water level 801, carrying the floating objects 101 through the overflow dam 107 and completing the separation and removal of the floating objects 101 from the water on the water filter slide 109.

[0071] Example 4

[0072] The use of steel beams to reinforce the block-type floating object guide body 104 and the sub-floating body 302 can meet the requirements of civil buildings, such as Figure 2 As shown, a commercial space 203 is set on the floating object guide body 104 and the sub-floating body 302. The income of the commercial space 203 is used to recover the investment in building the reservoir floating object diversion and removal device. The commercial space 203 can operate water leisure and vacation projects, such as fishing, swimming, science popularization or summer vacation.

[0073] A photovoltaic power generation device 201 can also be set up on the commercial space 203. The output power of the photovoltaic power generation device 201 fluctuates due to the influence of clouds, rain and snow. The output power is converted into a control signal through signal conversion and input into the control system of the hydroelectric generator to control the flow control gate 115 of the hydroelectric generator and adjust the power generation power of the hydroelectric system 117 so that the total output power of the generator system driven by the photovoltaic power generation device 201 and the hydroelectric system 117 meets the technical requirements for power access to the grid. The electricity generated by the photovoltaic power generation device 201 is further recovered for the investment in building a reservoir drift diversion and removal device.

[0074] The flow control gate 115 includes a second electric winch 1101 fixed on the dam body and a second gate plate 1103 connected to the second electric winch 1101 by transmission. The second gate plate 1103 is connected to the second electric winch 1101 via a second steel wire rope 1102. Figures 11 to 13 As shown, the control unit of the hydroelectric power generation system controls the second electric winch 1101 to rotate forward and reversely to drive the second steel wire rope 1102 to lift or lower the second gate plate 1103 to adjust the water inlet 114, thereby adjusting the output power of the hydroelectric generator.

[0075] The reservoir drift diversion and removal device not only obtains environmental and social benefits from the removal of floating objects, but also obtains cash flow benefits from operating water leisure and vacation projects and photovoltaic power generation devices 201 electricity sales. At the same time, the photovoltaic power generation device and hydropower generation are coupled to solve the problem of large fluctuations in photovoltaic power generation and low power generation in the dry season of hydropower generation. It solves the problem that the process of manual or mechanical removal of floating objects is costly, the reservoir operation and maintenance unit is short of funds and it is difficult to continue to invest funds, and the problem of manual or mechanical removal of floating objects is solved; it solves the problem that manual or mechanical removal of floating objects can obtain environmental benefits for society, but the reservoir operation and maintenance unit is difficult to obtain cash flow benefits.

[0076] Example 5

[0077] In order to facilitate the detection of the blockage of the water inlet 114 and give an early warning in a timely manner, a water inlet blockage warning system is also provided. Specifically, it includes a protective fence 206 arranged at the water inlet 114, a second image acquisition component 205 arranged at the lower end of the floating object guiding body 104, a warning device and a controller. A flow control gate 115 is provided downstream of the water inlet 114. The flow control gate 115, the second image acquisition component 205, the warning device, and the control unit of the hydraulic generator are electrically connected to the controller. The controller controls the opening and closing of the warning device, the hydraulic generator, and the flow control gate according to the data collected by the second image acquisition component 205. The second image acquisition component 205 uses a camera, and a flash lamp is arranged on the camera. The synchronization controller of the second image acquisition component 205 controls and coordinates the flash lamp and the underwater camera 205 to capture images. The warning device is arranged in the duty room or the controller forwards the warning to the mobile APP of the duty personnel.

[0078] When the number of blockages on the protective fence 206 collected by the second image acquisition component 205 exceeds the third threshold, a warning is given to the duty personnel. After the duty personnel handle the warning in a timely manner, the warning is lifted, or the hydraulic power generation system is shut down according to the procedure specified in the operation manual to remove the blocking object; when the number of blockages on the protective fence 206 collected by the second image acquisition component 205 exceeds the set fourth threshold, the controller sends the control signal generated by the number of blocking objects exceeding the set fourth threshold to the control unit of the hydraulic generator. The control unit of the hydraulic generator shuts down the hydraulic power generation system 117 and the flow control gate 115 and starts the manual maintenance process. Multiple underwater cameras can also be installed under the floating object guiding body 104 facing the water area where light is incident to collect images of the protective net 202. After image processing and finding that foreign objects larger than the specified size enter after the protective net is damaged, a warning is given to the duty personnel and the work of repairing the protective net 202 is arranged. The third threshold and the fourth threshold are determined according to the working conditions and parameters of the power generation system. For example, the third threshold can be set to 30%-45% of the area of the blocking object on the image accounting for the area of the protective fence 206, and the fourth threshold can be set to 45%-65% of the area of the blocking object on the image accounting for the area of the protective fence 206.

[0079] In summary, the floating object diversion and removal device can realize the automatic removal and collection of floating objects in the reservoir, with a simple structure and low cost.
