Description

Technical Field

[0001] This invention relates to the field of water conservancy facilities technology, specifically to a water source scheduling and diversion device for a reservoir. Background Technology

[0002] A reservoir is a water conservancy project used for domestic water supply, flood control, agricultural irrigation, hydroelectric power generation, and ecological improvement. It is mainly constructed by building dams at the narrowest points of mountain valleys or rivers to store water and form artificial lakes. In some drinking water source protection areas, there are high requirements for the water quality of the water flowing out of the reservoir.

[0003] Reservoir dams utilize water diversion devices to perform functions such as water storage and water source allocation. Existing water diversion devices for reservoir dams generally include components such as gates and gate plates. Gates are located on the dam, and gate plates are located inside the gates. By controlling the rise and fall of the gate plates within the gates, the water source is diverted or controlled. During long-term water storage, the reservoir water remains stagnant. At this time, algae, weeds, and other impurities can proliferate within the reservoir. Fallen leaves, branches, and garbage may also float on the surface, severely damaging the water quality and hindering water access for downstream personnel.

[0004] Existing water diversion devices for dams and reservoirs do not filter or remove water flowing out of the gates when the reservoir is opened. This makes it difficult to remove impurities such as algae, weeds, and garbage from the water flowing out of the reservoir, which is detrimental to ensuring the water quality of downstream water bodies. Furthermore, the presence of these impurities obstructs their flow when they pass through the gates, increasing the resistance to water flow and the impact force on the gates, thus affecting the service life and reliability of the entire diversion device. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems in the prior art and provide a water source scheduling and diversion device for a reservoir. This device can simultaneously schedule and divert water sources and cyclically remove floating algae, weeds, and garbage from the water filtered out of the reservoir, thereby cleaning up the impurities in the water. Furthermore, it can collect and process these impurities in a centralized manner.

[0006] This invention provides a water source diversion and regulation device for a reservoir, including a gate and a sluice gate, and further comprising:

[0007] The transmission mechanism includes a first transmission shaft, a second transmission shaft, and a transmission chain ring. The first transmission shaft is horizontally disposed to the right of the gate, and the first transmission shaft bearing is connected to the lower part of the gate.

The connecting block is connected to the transmission chain ring, and the screen is connected to the connecting block. The screen is provided with multiple staggered first grid teeth and first grid holes.

[0009] A collection trough is located above the gate and to the right of the transmission chain ring. The side wall of the collection trough is provided with a plurality of staggered second grid teeth and second grid holes. The first grid teeth can pass through the second grid holes, and the second grid teeth can pass through the first grid holes.

[0010] Preferably, the filtration mechanism further includes a connecting rod, a rotating shaft, and a slider. The screen is fixedly connected to the rotating shaft, and the rotating shaft is pivotally connected to the connecting block shaft. One end of the connecting rod is fixedly connected to the rotating shaft, and the other end of the connecting rod is connected to the slider. The gate is provided with a sliding groove, and the slider is slidably connected in the sliding groove. The sliding groove is divided into a left groove and a right groove. The left groove is located on the left side of the first drive shaft, and the right groove is located on the right side of the first drive shaft. The collection groove is located above and to the right of the right groove. When the slider is in the left groove, the screen remains horizontal under the limiting action of the left groove. When the slider is in the right groove, the screen forms a certain angle with the horizontal plane under the limiting action of the right groove.

[0011] Preferably, a base is provided below the gate, the base is located between the gate plate and the first drive shaft, and a third drive shaft is connected to the base by a bearing. The third drive shaft is arranged parallel to and connected to the first drive shaft, and the rotation direction of the third drive shaft is opposite to that of the first drive shaft. The third drive shaft is provided with a plurality of staggered third grid teeth and third grid holes. The first grid teeth can pass through the third grid holes, and the third grid teeth can pass through the third grid holes. Under the drive of the first drive shaft, the third grid teeth located above the third drive shaft move towards the direction of the first grid teeth.

[0012] Preferably, the base is provided with a slot and a groove, the lower end of the gate can be inserted into the slot, a hydraulic turbine is fixedly connected to the third drive shaft, the lower half of the hydraulic turbine is located in the groove, and the gate is provided with a first water passage hole.

[0013] Preferably, the gate plate is provided with a first water passage hole at a position below the water surface of the library. The first water passage hole faces the upper part of the hydraulic turbine. A passage groove is also provided below the gate plate. The passage groove passes through the first water passage hole. A partition is slidably connected in the passage groove. The partition is used to block the first water passage hole. A second water passage hole is provided on the partition. The sliding partition can make the first water passage hole and the second water passage hole communicate.

[0014] Preferably, the screen has a filter plate perpendicular to the screen on the side near the connecting block. The filter plate has a plurality of staggered fourth grid teeth and fourth grid holes. The fourth grid teeth can pass through the second grid holes, and the second grid teeth can pass through the fourth grid holes.

[0015] Preferably, the bottom of the collection tank is provided with a conveyor belt, and the tank wall is provided with a guide block. The guide block is used to guide impurities entering the collection tank. The conveyor belt is located at the bottom end of the guide block and is connected to the second drive shaft.

[0016] Preferably, the gate is connected to a vertically arranged lead screw via a bearing, the gate plate is provided with a lead screw nut sleeve, the lead screw nut sleeve is threadedly connected to the lead screw, and the third transmission shaft is connected to the lead screw via a worm gear mechanism.

[0017] Preferably, the lead screw is equipped with an electronically controlled clutch, which is connected to the third transmission shaft via a worm gear mechanism. A limit switch is provided at the top of the gate, and the limit switch is electrically connected to a controller. The controller is electrically connected to the electronically controlled clutch. When the lead screw drives the gate plate to move to the top of the gate, the gate plate abuts against the limit switch, the limit switch is triggered, and the controller controls the electronically controlled clutch to disengage from the lead screw.

[0018] Preferably, the inner wall of the collection tank is provided with a wear-resistant coating.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The water source regulation and diversion device for a reservoir of the present invention can simultaneously regulate and divert water source flow while cyclically scooping up floating algae, weeds, and garbage from the water filtered out of the reservoir, thereby cleaning up impurities in the water and collecting and processing these impurities. Since this device eliminates the risk of the screen being clogged by impurities in the water, it greatly reduces the resistance of the screen to the water flow and reduces the impact force of the water flow from the gate on the entire device. This not only prevents unfavorable water flow at the gate but also prevents damage to the entire device caused by the impact force exerted by the water flow on the screen.

[0020] Through connecting rods, rotating shafts, and chutes, when the screening mechanism is driven by the transmission chain to the collection tank, the screen of the screening mechanism is automatically driven to rotate by the connecting rods and rotating shafts under the guidance of the chutes. This allows the second grid teeth on the side wall of the collection tank to scrape away the floating algae, aquatic plants, and debris adhering to the first grid teeth on the screen to the maximum extent, further improving the cleanliness of the water flowing out of the reservoir. Through the third transmission shaft and the third grid teeth, the first transmission shaft simultaneously drives the third transmission shaft to rotate, thereby driving the third grid teeth located above the third transmission shaft to move towards the first grid teeth. This rakes the floating algae, aquatic plants, and debris in the water onto the first grid teeth and prevents them from being washed away by the water flow, thus more thoroughly removing the floating algae, aquatic plants, and debris from the water. The hydraulic turbine automatically drives the first and third drive shafts to rotate the moment the reservoir gates are opened to release water. This ensures that the first and third grid teeth rotate promptly as water flows through the gates, preventing water from leaking through the screen and further enhancing the filtration effect and water purity. Before the gates are opened, the water flowing from the first water passage below the water surface on the baffle plate drives the hydraulic turbine in advance. This reduces disturbance to algae and aquatic plants on the water surface, allowing the first and third grid teeth to pre-collect algae and aquatic plants near the third shaft on the gate before the gates are opened, further improving the purity of the water flowing downstream. The filter plates, perpendicular to the screen, provide resistance when the screen collects algae, aquatic plants, and debris, preventing the water flow from washing them away and further ensuring the water quality of the water flowing out of the reservoir. A conveyor belt transports algae, aquatic plants, and debris out of the collection tank, preventing it from becoming clogged and ensuring stable long-term operation, thus guaranteeing the quality of downstream water. The water flow power drives the gate's lifting, eliminating the need for a separate drive unit, improving both the reliability and energy efficiency of the entire diversion device. An electronically controlled clutch and limit switch automatically disengage the clutch from the lead screw when the gate is fully open, preventing collisions between the gate driven by the third drive shaft and the gate itself. A wear-resistant coating on the inner wall of the collection tank enhances its durability, extending the lifespan of the entire diversion device. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] like Figure 1-4As shown, the present invention provides a water source scheduling and diversion device for a reservoir, including a gate 101 and a gate plate 102, and further including: a transmission mechanism, multiple screening mechanisms 107 and a collection tank 111. The transmission mechanism includes a first transmission shaft 104, a second transmission shaft 105 and a transmission chain 106. The first transmission shaft 104 is horizontally arranged to the right of the gate plate 102 and is bearing-connected to the lower part of the gate 101. The second transmission shaft 105 is horizontally arranged to the right of the gate plate 102 and is bearing-connected to the upper part of the gate 101. The transmission chain 106 is connected to the first transmission shaft 104 and the second transmission shaft 105. A drive shaft 105 is connected; multiple screening mechanisms 107 are evenly arranged on the transmission chain ring 106. Each screening mechanism 107 includes a connecting block 108 and a screen 109. The connecting block 108 is connected to the transmission chain ring 106, and the screen 109 is connected to the connecting block 108. The screen 109 is provided with multiple staggered first grid teeth 110 and first grid holes. A collection trough 111 is located above the gate 101 and on the right side of the transmission chain ring 106. The side wall of the collection trough 111 is provided with multiple staggered second grid teeth 103 and second grid holes. The first grid teeth 110 can pass through the second grid holes, and the second grid teeth 103 can pass through the first grid holes.

[0030] The working principle of Example 1 is briefly described below:

[0031] In use, this device utilizes a gate 102 to block the water flow. When it is necessary to regulate the water source in the reservoir, the gate 102 is raised, releasing the water flow. The water flows from the left side of the gate 101 to the right side, driving the first drive shaft 104 to rotate. The rotating first drive shaft 104 drives the drive chain ring 106 to rotate, thereby driving the second drive shaft 105 connected to it to rotate. As the drive chain ring 106 rotates, the connecting block 108 on the left side of the drive chain ring 106 rises, and the connecting block 108 on the right side of the drive chain ring 106 falls. The rising connecting block 108 drives the screen 109 on it to rise, thereby using the raised screen 109 to scoop up floating algae, aquatic plants, garbage, and other impurities in the water flow. When the screen 109 rotates with the connecting block 108 to the right side of the transmission chain ring 106, the screen 109 moves downward and flips, causing the floating algae, aquatic plants, and debris on the screen 109 to fall into the collection tank 111, thereby filtering the water flow from the reservoir. When the screen 109 moves to the point where the first grid teeth 110 on the screen 109 pass through the second grid hole on the side wall of the collection tank 111, the floating algae, aquatic plants, and debris adhering to the first grid teeth 110 are scraped off by the second grid teeth 103 on the side wall of the collection tank 111, thus cleaning the screen 109. This not only prevents the screen from clogging but also prevents the floating algae, aquatic plants, and debris screened out of the reservoir from re-entering the reservoir water, thereby ensuring the cleanliness of the water flowing out of the reservoir.

[0032] This invention discloses a reservoir water source diversion and regulation device that, while diverting water sources, can simultaneously perform cyclical dredging of floating algae, weeds, and garbage in the water flowing out of the reservoir, thereby cleaning up impurities in the water and collecting and processing them. Since this device eliminates the risk of the screen 109 becoming clogged by impurities in the water, it significantly reduces the resistance of the screen 109 to the water flow and reduces the impact force of the water flowing out of the gate 109 on the entire device. This not only prevents unfavorable water flow at the gate 101 but also prevents damage to the entire device caused by the impact force exerted by the water flow on the screen 109.

[0033] Example 2:

[0034] Based on Example 1, in order to scrape away the floating algae, aquatic plants and debris adhering to the first grid teeth 110 to the greatest extent possible, and further improve the cleanliness of the water flowing out of the reservoir.

[0035] like Figure 1-4 As shown, the filtration mechanism 107 further includes a connecting rod 201, a rotating shaft 202, and a slider 203. The screen 109 is fixedly connected to the rotating shaft 202, which is pivotally connected to the connecting block 108. One end of the connecting rod 201 is fixedly connected to the rotating shaft 202, and the other end is connected to the slider 203. The gate 101 is provided with a sliding groove, and the slider 203 is slidably connected within the sliding groove. The sliding groove is divided into a left dividing groove 204 and a right dividing groove 205. The groove 205 has a left sub-groove 204 located to the left of the first drive shaft 104 and a right sub-groove 205 located to the right of the first drive shaft 104. The collection groove 111 is located above and to the right of the right sub-groove 205. When the slider 203 is located in the left sub-groove 204, the screen 109 remains horizontal under the limiting action of the left sub-groove 204. When the slider 203 is located in the right sub-groove 205, the screen 109 forms a certain angle with the horizontal plane under the limiting action of the right sub-groove 205.

[0036] When the screening mechanism 107 on the left side of the transmission chain ring 106 is raised, the slider 203 on the screening mechanism 107 is located in the left slot 204. Under the limiting action of the left slot 204, the connecting rod 201 restricts the rotation of the rotating shaft 202, thereby keeping the screen 109 on the screening mechanism 107 horizontal. The raised horizontal screen 109 can filter out floating algae, aquatic plants and garbage in the water to the maximum extent. As the transmission chain 106 rotates, the filtration mechanism 107 rotates to the right side of the transmission chain 106. At this time, the filtration mechanism 107 descends, and the slider 203 on the filtration mechanism 107 is located in the right slot 205. Under the limiting action of the right slot 205, the connecting rod 201 drives the rotating shaft 202 to rotate, causing the screen 109 to form a certain angle with the horizontal plane. At this time, the first grid tooth 110 on the screen 109 passes through the second grid hole on the side wall of the collection tank 111. The first grid tooth 110 and the second grid tooth 103 on the side wall of the collection tank 111 have a certain angle, so that the second grid tooth 103 can scrape off the floating algae, aquatic plants and garbage adhering to the first grid tooth 110 to the maximum extent, further improving the cleanliness of the water flowing out of the reservoir. Through the connecting rod 201, rotating shaft 202, and sliding groove, when the transmission chain ring 106 drives the filtration mechanism 107 to move to the collection tank 111, under the guidance of the sliding groove, the connecting rod 201 and rotating shaft 202 automatically drive the screen 109 of the filtration mechanism 107 to rotate, so that the second grid teeth 103 on the side wall of the collection tank 111 can scrape off the floating algae, aquatic plants, and garbage adhering to the first grid teeth 110 on the screen 109 to the maximum extent, further improving the cleanliness of the water flowing out of the reservoir.

[0037] Example 3:

[0038] Based on Example 2, in order to automatically drive the first drive shaft 104 to rotate when the reservoir gate is opened to release water, thereby driving the screen 109 to filter the water in a timely manner, and thus further improving the cleanliness of the water.

[0039] like Figure 1 and 2 As shown, a base 304 is provided below the gate 101. The base 304 is located between the gate plate and the first drive shaft 104. A third drive shaft 302 is connected to the base 304 by a bearing. The third drive shaft 302 is arranged parallel to and connected to the first drive shaft 104. The rotation direction of the third drive shaft 302 is opposite to the rotation direction of the first drive shaft 104. The third drive shaft 302 is provided with a plurality of staggered third grid teeth 301 and third grid holes. The first grid teeth 110 can pass through the third grid holes, and the third grid teeth 301 can pass through the third grid holes. Under the drive of the first drive shaft 104, the third grid teeth 301 located above the third drive shaft 302 move towards the first grid teeth 110.

[0040] Under normal conditions, the reservoir's water body is blocked by the gate 102, at which time the third drive shaft 302 and the first drive shaft 104 are stationary. When it is necessary to open the gate to release water, the gate 101 is raised, and the water flows through the gate 101. At this time, the third drive shaft 302 is driven to rotate, and the third drive shaft 302 drives the first drive shaft 104 to rotate. Since the rotation direction of the third drive shaft 302 is opposite to that of the first drive shaft 104, under the drive of the third drive shaft 302 and the first drive shaft 104, the third grid tooth 301 located above the third drive shaft 302 moves towards the first grid tooth 110. When the third grid tooth 301 moves towards the first grid tooth 110, it will rake the floating algae, aquatic plants, and garbage in the water body onto the first grid tooth 110, and prevent the floating algae, aquatic plants, and garbage from being washed away by the water flow from the first grid tooth 110, thereby more thoroughly removing the floating algae, aquatic plants, and garbage from the water body.

[0041] As a preferred option, such as Figure 1 and 2 As shown, the base 304 is provided with a slot and a groove 305, the lower end of the gate plate 102 can be inserted into the slot, a hydraulic turbine 303 is fixedly connected to the third drive shaft 302, the lower half of the hydraulic turbine 303 is located in the groove 305, and the gate plate 102 is provided with a first water passage hole 401. When the gate 102 closes the gate 101, the lower end of the gate 102 is locked in the slot. When the gate is opened to release water, the gate 101 is raised and the water flows through the gate 101. Since the lower half of the hydraulic turbine 303 is located in the groove 301, the water flows towards the upper half of the hydraulic turbine 303, thereby driving the hydraulic turbine 303 to rotate. Under the drive of the hydraulic turbine 303, the third drive shaft 302 and the first drive shaft 104 rotate simultaneously. The third grid tooth 301 located above the third drive shaft 302 moves towards the first grid tooth 110. The third grid tooth 301 is used to rake the floating algae, aquatic plants and garbage in the water onto the first grid tooth 110. The hydraulic turbine 303 automatically drives the first drive shaft 104 and the third drive shaft 302 to rotate when the reservoir gate is opened to release water. This drives the first grid tooth 110 and the third grid tooth 301 to rotate in time when the water flows through the gate 101, preventing the water flowing out of the reservoir from passing through the screen. This further improves the filtration effect of the device and enhances the cleanliness of the water.

[0042] As a preferred option, such as Figure 1 and 2As shown, the gate 102 has a first water passage 401 located below the water surface in the reservoir. The first water passage 401 faces the upper part of the hydraulic turbine 303. A channel is also provided below the gate 102, passing through the first water passage 401. A partition 402 is slidably connected within the channel, blocking the first water passage 401. The partition 402 has a second water passage 403, and sliding the partition 402 allows the first water passage 401 to communicate with the second water passage 403. When the gate 102 is in the slot on the base 304, the first water passage 401 is blocked by the partition 402, thus blocking the water in the reservoir. When the reservoir has not released water for a long time, the water near the gate 101 is in a stagnant state. At this time, some algae and aquatic plants will grow on the side of the gate plate 102 near the third rotating shaft 302. After the gate 101 is opened, before the third rotating shaft 302 has a chance to be driven by the water flow, these algae and aquatic plants will be carried downstream by the water flow, resulting in the problem of incomplete removal of impurities from the water. When the sliding baffle 402 is connected to the second water passage 403 on the baffle 402 and the first water passage 401 on the gate 102, the water in the reservoir passes through the first water passage 401 and the second water passage 403. Since the algae and aquatic plants generally float above the water surface of the reservoir and the first water passage 401 is located on the gate 102 below the water surface, the water flow from the first water passage 401 and the second water passage 403 causes less disturbance to the algae and aquatic plants on the side of the gate 102 near the third rotating shaft 302. At this time, before the gate is opened to release water, the water flow from the first water passage 401 below the water surface on the baffle 402 drives the hydraulic turbine 303 to rotate in advance, thereby driving the first grid tooth 110 and the third grid tooth 301 to scoop up the algae and aquatic plants on the side of the gate 102 near the third rotating shaft 302 before the gate is opened to release water, thereby further improving the cleanliness of the water flowing downstream.

[0043] As a preferred option, such as Figure 1-4 As shown, the screen 109 has a filter plate 601 perpendicular to it on the side near the connecting block 108. The filter plate 601 has multiple staggered fourth teeth 602 and fourth holes. The fourth teeth 602 can pass through the second holes, and the second teeth 103 can pass through the fourth holes. When the screen 109 is raised to scoop up algae, aquatic plants, and debris in the water, the screen 109 is parallel to the horizontal plane. At this time, the algae, aquatic plants, and debris attached to the first teeth 110 of the screen 109 have little resistance along the water flow direction and are easily washed away by the water flow. By setting up the filter plate 601, which is perpendicular to the screen 109, it provides some resistance to these debris when the screen 109 scoops up algae, aquatic plants, and debris, thus preventing the water flow from washing away the algae, aquatic plants, and debris scooped up from the screen 109, further ensuring the water quality of the water flowing out of the reservoir.

[0044] As a preferred option, such as Figure 1 and 4 As shown, the bottom of the collection tank 111 is equipped with a conveyor belt 701, and the tank wall is equipped with guide blocks 702. The guide blocks are used to guide impurities entering the collection tank. The conveyor belt 701 is located at the bottom of the guide blocks 702 and is connected to the second drive shaft 105. By setting up the conveyor belt 701, impurities such as algae, aquatic plants, and garbage entering the collection tank can fall onto the conveyor belt under the guidance of the guide blocks 702. The second drive shaft 105 drives the conveyor belt to transport the algae, aquatic plants, and garbage collected into the collection tank 111 in a timely manner, thereby preventing the collection tank 111 from being filled with algae, aquatic plants, and garbage, thus ensuring the long-term stable operation of this device and further ensuring the quality of the downstream water body.

[0045] As a preferred option, such as Figure 1 As shown, a vertically mounted lead screw 501 is connected to a bearing on the gate 101, and a lead screw nut is provided on the gate plate 102. The lead screw nut is threadedly connected to the lead screw 501, and the third drive shaft 302 is connected to the lead screw 501 via a worm gear mechanism. When the water flow drives the third drive shaft 302 to rotate, the third drive shaft 302 drives the lead screw 501 to rotate via the worm gear mechanism. The lead screw 501 drives the threaded lead screw nut to rise, thereby driving the gate plate 102 to rise, so that the gate 101 opens. The gate 101 is lifted by the power of the water flow, eliminating the need for a separate drive device. This not only improves the reliability of the entire diversion device but also enhances its energy efficiency.

[0046] As a preferred option, such as Figure 1As shown, the lead screw 501 is engaged with an electronically controlled clutch, which is connected to the third drive shaft 302 via a worm gear mechanism. A limit switch 502 is located at the top of the gate 101, electrically connected to a controller. The controller is also electrically connected to the electronically controlled clutch. When the lead screw 501 drives the gate plate 102 to the top of the gate 101, the gate plate 102 abuts against the limit switch 502, triggering the limit switch. The controller then disengages the electronically controlled clutch from the lead screw 501. During gate opening, the third drive shaft 302 is connected to the lead screw 501 via the electronically controlled clutch and the worm gear mechanism. The rotating third drive shaft 302 drives the lead screw 501 to rotate via the worm gear mechanism and the electronically controlled clutch, thereby raising the gate plate 102. When the gate 102 is raised to the point where it abuts against the limit switch 502 at the top of the gate 101, the limit switch 502 is triggered. The controller then controls the electronic clutch to disengage from the lead screw 501, allowing the third drive shaft 302 to rotate normally. At this point, the gate 102 is raised to its highest position, and the gate 101 is fully open. Through the electronic clutch and limit switch 502, when the third drive shaft 302 drives the gate 101 to fully open, the gate trigger forms a switch, automatically controlling the electronic clutch to disengage from the lead screw 501. This prevents the gate 102 from colliding with the gate 101 when the third drive shaft 302 drives the first and second gears 103 to rotate after the gate 101 is open.

[0047] As a preferred option, such as Figure 1 As shown, the inner wall of the collection tank 111 is provided with a wear-resistant coating.
