Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy, in particular to a water diversion structure for water conservancy and hydropower engineering. BACKGROUND

[0002] In the water diversion system of water conservancy and hydropower engineering, fixed filter screens are generally used to filter the sediment in the water flow. For example, the traditional water diversion structure intercepts impurities in the water through a metal filter plate. However, after long-term operation, the sediment is easy to block the filter holes, resulting in increased water flow resistance, decreased water diversion efficiency, and unbalanced water pressure before and after the filter screen if not cleaned in time. The water pressure near the water inlet end of the filter screen rapidly rises, causing the water pumping equipment to overload and the pipeline to burst, posing safety hazards. For example, during the flood season or in high-sediment water flow environments, the traditional filter screen is prone to blockage, which affects the actual water diversion efficiency.

[0003] In view of this, the present application provides a water diversion structure for water conservancy and hydropower engineering. SUMMARY

[0036] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] The present application will be further described below with reference to the embodiments.

[0038] A water diversion structure for a water conservancy and hydropower project includes a water diversion unit 100, comprising a vortex tank 101, a pump 102 disposed at the inlet end of the vortex tank 101, and an outlet valve 103 disposed at the outlet end of the vortex tank 101; a filtration unit 300, comprising a filter assembly 301 disposed inside the vortex tank 101, and a fixing assembly 302 for installing and positioning the filter assembly 301; and a control unit 200, comprising a tank assembly 201 disposed on the vortex tank 101, an alarm control assembly 202 disposed on the tank assembly 201, and a trigger assembly 203 disposed on the tank assembly 201. When the water flow of the filter assembly 301 decreases, the alarm control assembly 202 is triggered to issue an audible and visual alarm and to stop the pump 102.

[0039] It should be noted that an external water pipe can be connected to the inlet end of the water pump 102 for water pumping and drawing. By starting the water pump 102, water can be pumped into the vortex water tank 101 and discharged through the outlet valve 103 at the outlet end of the vortex water tank 101. An external water pipe can be connected to the outlet end of the outlet valve 103 to guide the water to a designated location.

[0040] Specifically, the tank assembly 201 includes a floating water level tank 2011 disposed on the side of the filter assembly 301 near the water inlet end of the vortex water tank 101 and fixedly connected to the top of the vortex water tank 101, and a cover plate 2012 on the top of the floating water level tank 2011.

[0041] It should be noted that during normal operation, the inflow of water from the pump 102 and the outflow of water from the filter assembly 301 maintain a dynamic balance. At this time, the water level and pressure inside the vortex tank 101 are stable, and the water level on the side of the filter assembly 301 near the pump 102 is lower than that in the floating water level chamber 2011. Only when the filter assembly 301 is severely clogged with sediment will the water flow through it decrease. Since the pump 102 is still operating at this time, the water flow through the filter assembly 301 will decrease. The water level on the side near the inlet of the vortex water tank 101 continues to rise until the water enters the floating water level chamber 2011 at the top of the vortex water tank 101. Only when the water level in the floating water level chamber 2011 continues to rise to the corresponding height can the alarm control component 202 be triggered by the trigger component 203 to perform an audible and visual alarm and control the water pump 102 to stop. This can effectively prevent the water pump 102 from accidentally triggering the alarm control component 202 due to water pressure fluctuations at the moment of water inlet when the water output of the filter component 301 is normal.

[0042] Further, the vortex water tank 101 is internally provided with a power generation assembly 104, which includes a conical flow guide 1041 fixedly connected to the inner wall of the vortex water tank 101, turbine blades 1043 coaxially arranged with the conical flow guide 1041, and a generator 1044 fixedly connected to the inner wall of the vortex water tank 101, the inner wall of the turbine blades 1043 is fixedly connected with a fixed shaft 1042, the bottom of the fixed shaft 1042 is connected with the input end of the rotor inside the generator 1044, and the top of the fixed shaft 1042 is rotatably connected to the inner wall of the vortex water tank 101. The filter assembly 301 is provided with a flap 105 rotatably connected to the inner wall of the vortex water tank 101 away from the water inlet side of the vortex water tank 101, and the flap 105 is flipped upward by water impact under normal water flow condition of the filter assembly 301.

[0043] It should be noted that when the water pump 102 is normally operating and the filter assembly 301 is not seriously blocked, the normal water flow impact force can impact the flap 105 to flip it upward and open it, so that water can enter the conical flow guide 1041. The vortex design of the vortex water tank 101 and the arrangement of the conical flow guide 1041 can improve the centrifugal force of the water entering the conical flow guide 1041, so that a strong vortex can be formed at the center of the conical flow guide 1041, thereby improving the water force to drive the turbine blades 1043 to rotate rapidly. At the same time, the fixed shaft 1042 can drive the rotor inside the generator 1044 to rotate, thereby realizing hydroelectric power generation, and the electric energy can be used to power the alarm control assembly 202 and other related electrical components of the water pump 102;

[0044] Specifically, the fixed assembly 302 includes a strip-shaped clamping groove 3021 formed in the inner wall of the vortex water tank 101, and a rectangular groove 3022 formed on one side of the vortex water tank 101. The filter assembly 301 includes a T-shaped bracket 3011 clamped in the strip-shaped clamping groove 3021, a fixed hole 3013 is formed on one side of the T-shaped bracket 3011, the T-shaped bracket 3011 is fixedly connected to the inner wall of the rectangular groove 3022 through the bolt 3014 in the fixed hole 3013, and the inner wall of the T-shaped bracket 3011 is fixedly connected with a metal filter plate 3012.

[0045] It should be noted that the T-shaped bracket 3011 can be clamped and positioned by the strip-shaped clamping groove 3021 in the vortex water tank 101, and the T-shaped bracket 3011 can be fixed in the rectangular groove 3022 on one side of the vortex water tank 101 by the bolt 3014 in the fixed hole 3013 of the T-shaped bracket 3011, thereby ensuring the stability of the metal filter plate 3012 on the T-shaped bracket 3011 during use, and the metal filter plate 3012 can filter the silt in the water during normal drainage operation;

[0046] Specifically, the alarm control assembly 202 comprises an audible and light alarm 2021 fixedly connected to the top of the cover plate 2012, and an alarm pressure switch 2022 electrically connected to an output end of the audible and light alarm 2021, and fixedly connected to the bottom of the cover plate 2012. The alarm control assembly 202 further comprises a water pump switch 2023 fixedly connected to one side of the floating water level bin 2011, and an input end of the water pump 102 is electrically connected to an output end of the water pump switch 2023. The water pump switch 2023 is fixedly connected with a switch push rod 2027 through an internal conductive contact piece. A telescopic rod 2025 is rotatably connected to an end of the switch push rod 2027 away from the conductive contact piece. A gear 2026 is fixedly connected to an end of the telescopic rod 2025 away from the switch push rod 2027 through a connecting shaft 2024 penetrating the floating water level bin 2011 in rotation.

[0047] Further, the trigger assembly 203 comprises a limiting frame 2031 fixedly connected to an inner wall of the floating water level bin 2011, and a three-pronged top rod 2032 is arranged in the limiting frame 2031. The three-pronged top rod 2032 is slidingly connected to the inner wall of the limiting frame 2031 through a limiting strip 20321 on the surface of the three-pronged top rod 2032. A floating ball 2033 is fixedly connected to the bottom of the three-pronged top rod 2032 and sleeved to the inner wall of the floating water level bin 2011. A rubber pad 2035 is fixedly connected to the top of the three-pronged top rod 2032 and used for pressing the alarm pressure switch 2022. Magnetic sheets 2034 are arranged on both sides of the rubber pad 2035 and fixedly connected to the top of the three-pronged top rod 2032. An electromagnetic block 2036 is arranged above the magnetic sheets 2034 and fixedly connected to the bottom of the cover plate 2012. A gear rack 2037 is further fixedly connected to one side of the three-pronged top rod 2032 and engaged with the gear 2026 in transmission.

[0048] It should be noted that as the pumping operation is carried out, more and more water enters the vortex water tank 101, and the silt adhering and accumulating on the metal filter plate 3012 can be more and more, at this time the blockage of the filter holes of the metal filter plate 3012 can be more serious, so that the water flow through the metal filter plate 3012 can also be smaller, when the water flow is relatively small, the smaller water flow is not enough to impact the flap 105 to open, at this time the flap 105 is reset by its own gravity and turns down, only a small amount of water can overflow from the flap 105 and flow to the conical guide chute 1041, at this time the turbine blades 1043 and other power generation components 104 can stop rotating due to insufficient water flow impact, at this time the metal filter plate 3012 is close to the water pump 102 side of the vortex water tank 101, the local water level of the vortex water tank 101 rises rapidly, after the local water level of the vortex water tank 101 rises to a certain height, water can enter the floating water level bin 2011, as the water level in the floating water level bin 2011 continues to rise, it can drive the floating ball 2033 to rise, when the floating ball 2033 rises to a certain height, the gear rack 2037 on one side of the three-pronged top rod 2032 is about to contact the gear 2026, due to the magnetic sheet 2034 provided on the three-pronged top rod 2032 and the electromagnetic block 2036 at the bottom of the cover plate 2012, magnetic attraction is generated, so that the three-pronged top rod 2032 rises faster at this time, when the electromagnetic block 2036 and the magnetic sheet 2034 generate attraction, the gear rack 2037 starts to mesh with the gear 2026 to transmit, thereby driving the gear 2026 to rotate, the connecting shaft 2024 connected with the gear 2026 can drive the telescopic rod 2025 at one end to rotate, the rotation of the telescopic rod 2025 can drive the switch push rod 2027 in the water pump switch 2023 to rotate, thereby stopping the water pump 102, to avoid that the water flow cannot pass through the metal filter plate 3012 quickly, if the pumping continues, it can cause the local pressure of the vortex water tank 101 to be too large, causing the vortex water tank 101 to burst and the water pump 102 and related components to be damaged, at the same time after the electromagnetic block 2036 and the magnetic sheet 2034 are attracted, the rubber pad disc 2035 normally presses the upper alarm pressure switch 2022, thereby opening the sound and light alarm 2021, through the sound and light alarm 2021, light flashing and whistle type alarm can be generated, which can remind the staff that the metal filter plate 3012 needs to be cleaned or replaced, by unscrewing the bolts 3014 fixed between the T-shaped frame 3011 and the vortex water tank 101, and then through the handle of the T-shaped frame 3011, the T-shaped frame 3011 and the metal filter plate 3012 can be taken out, since the water pump 102 has been stopped at this time, and the distance from the metal filter plate 3012 to the water inlet end of the vortex water tank 101 is not long, at this time the water in the vortex water tank 101 is also not much, when the metal filter plate 3012 is taken out, the water in this section can be allowed to flow out, the rubber pad disc 2035 on the three-pronged top rod 2032 is made of rubber material, when the electromagnetic block 2036 and the magnetic sheet 2034 are attracted, the rubber pad disc 2035 quickly presses the alarm pressure switch 2022,The certain buffer elastic function can avoid the impact on the alarm pressure switch 2022 being too large, causing the internal components of the switch to be damaged, the alarm pressure switch 2022 adopts a buffer structure of elastic material, such as silicone rubber, and a high-strength shell, such as stainless steel, and is connected with an elastic contact or a piezoresistor sensor through a pressure transmission rod inside, triggers the contact on-off or the sensor signal change when being pressed, opens the sound and light alarm 2021, and a sealing ring, such as a fluorine rubber O-ring, is arranged between the shell and the transmission part, so as to ensure the sealing and waterproof performance, and the inner wall of the floating ball 2033 and the floating water level bin 2011 is sleeved, so that water can not overflow above the floating ball 2033, and the movement of the related components, such as the triggering component 203 above the floating ball 2033, is affected.

[0049] When the metal filter plate 3012 is cleaned and replaced, the T-shaped frame 3011 can be inserted into the strip-shaped clamping groove 3021 and the rectangular groove 3022, and fixed through the bolt 3014, so that the installation of the metal filter plate 3012 is completed. After the installation is completed, the staff controls the switch of the electromagnetic block 2036 from the outside, so that the electromagnetic block 2036 is powered off, thereby releasing the adsorption of the magnetic sheet 2034. At this time, due to the gravity of the three-pronged top rod 2032 on the floating ball 2033 and the related components on the floating ball 2033, the floating ball 2033 and the related components can fall and reset. At the same time of falling, the rack 2037 can drive the gear 2026 to slowly rotate in the reverse direction, so as to reversely push the switch push rod 2027. The water pump switch 2023 is opened to start the water pump 102, and the water is pumped again. When the rubber pad 2035 moves downward with the three-pronged top rod 2032, the alarm pressure switch 2022 is not pressed, so that the sound and light alarm 2021 is turned off. When the normal water pumping operation is restored, the rack 2037 and the gear 2026 are completely separated and do not contact. The distance between the magnetic sheet 2034 and the electromagnetic block 2036 at this time is also more than the distance between them that can produce magnetic adsorption. At this time, the staff can make the electromagnetic block 2036 re-powered through the external switch for subsequent operation.

[0050] The working principle of the present application is that the water pump 102 is powered on to pump water through the water inlet end of the external water pipe. The water flows into the internal part through the water inlet end of the vortex water tank 101. Due to the large power of the water pump 102, the water flow generates strong impact force to push the flap 105. The flap 105 is made of polypropylene material with a density of 0.9-0.91 g / cm³ and a thickness of 3-5 mm. Its self-weight and water flow impact force threshold are matched through mechanical calculation to ensure that it is only opened when the filter assembly 301 is normally flowing, and it can be reliably reset when it is blocked. When the flap 105 normally flips upward to open, the water flow needs to pass through the metal filter plate 3012 first, and the sediment in the water is intercepted by the filter plate. The filtered water flows into the conical guide bucket 1041 through the flap 105, and is finally discharged to the designated water diversion position by the water outlet valve 103.

[0051] The water flow enters the conical guide chute 1041, and due to the scroll casing design of the vortex water tank 101 and the guide effect of the conical guide chute 1041, a high-speed rotating vortex is formed, driving the turbine blades 1043 to rotate at high speed around the fixed shaft 1042, the bottom of the fixed shaft 1042 is rigidly connected with the rotor of the generator 1044, the stator of the generator 1044 is fixed in the generator 1044, and the rotor is coaxially connected with the turbine blades 1043 through the fixed shaft 1042; when the turbine blades 1043 rotate, the permanent magnet on the rotor cuts the stator winding to generate induced current;

[0052] The power output by the generator 1044 directly supplies power to the sound-light alarm 2021 through wires; at the same time, the power can be stored in the built-in battery or connected to the external power grid to provide part of the working power supply for the water pump 102, and combined with the external circuit system, the energy conversion and recycling of “hydrokinetic energy into mechanical energy and then into electrical energy” are realized;

[0053] When the metal filter plate 3012 is seriously blocked by silt accumulation, the water flow is greatly reduced, which is not enough to maintain the opening of the flap 105, the flap 105 is reset to the horizontal state due to its own weight, only a small amount of water flows from the edge, the vortex in the conical guide chute 1041 disappears, the turbine blades 1043 stop rotating, and the power generation function stops synchronously;

[0054] In the vortex water tank 101, the water pressure and water level near the water pump 102 side of the filter assembly 301 continuously rise due to water retention, so that water can enter the floating water level bin 2011 above the vortex water tank 101, and the water level of the floating water level bin 2011 continuously rises with the continuous pumping operation of the water pump 102, thereby driving the floating ball 2033 to rise, the floating ball 2033 is sleeved on the inner wall of the floating water level bin 2011, which can prevent water overflow, and through the limiting and guiding effect of the limiting strip 20321 and the limiting frame 2031, the three-pronged top rod 2032 can vertically rise along the limiting frame 2031, the floating ball 2033 drives the rubber pad disc 2035 and the magnetic sheet 2034 on the top to synchronously move up through the three-pronged top rod 2032,

[0055] When the magnetic sheet 2034 rises to approach the electromagnetic block 2036, the constant magnetic field is generated under normal power supply, the magnetic attraction accelerates the upward movement of the three-pronged top rod 2032, at this time, the rack 2037 on one side of the three-pronged top rod 2032 engages with the gear 2026, driving the connecting shaft 2024 on the gear 2026 to rotate, and pushing the switch push rod 2027 to rotate through the shaft end telescopic rod 2025;

[0056] When the switch push rod 2027 rotates, the internal moving contact piece of the water pump switch 2023 is displaced and separated from the static contact piece, cutting off the power supply circuit of the water pump 102, so that it stops working, thereby avoiding the pressure overload of the vortex water tank 101 caused by continuous pumping;

[0057] The rubber pad 2035 is made of rubber material and has a buffering effect. When it rises to press the alarm pressure switch 2022, the alarm pressure switch 2022 is internally provided with an elastic silica rubber structure. When it is pressed, the contact is closed, the circuit of the sound and light alarm 2021 is turned on, the sound and light alarm 2021 is enabled to emit light and sound, and the staff is prompted to clean or replace the metal filter plate 3012.

[0058] After the staff completes the cleaning or replacement of the metal filter plate 3012, the external control switch is turned off to disconnect the power supply of the electromagnetic block 2036, the magnetic force disappears, and the components such as the three-pronged top rod 2032 and the floating ball 2033 fall and reset due to gravity.

[0059] During the falling process, the rack 2037 drives the gear 2026 to rotate in the reverse direction, the retractable rod 2025 pushes the switch push rod 2027 to reset, the moving contact piece and the static contact piece of the water pump switch 2023 are re-closed, the water pump 102 resumes the power-on operation, the rubber pad 2035 is separated from the alarm pressure switch 2022, the internal elastic structure of the switch is reset, the contact is disconnected, the sound and light alarm 2021 stops working, the staff reconnects the power supply of the electromagnetic block 2036, and the system returns to the initial standby state, ready for the next operation.

[0060] The one-way conduction of the turning plate 105 is only opened when the water flow impact force is greater than its own gravity, ensuring that the filtered water flow enters the conical guide hopper 1041 first, and the water flow is automatically blocked when the metal filter plate 3012 is severely clogged, so that the water level of the floating water level bin 2011 can quickly rise to trigger the stop logic. The guide sealing of the limiting frame 2031 and the floating ball 2033 ensures that the floating ball 2033 vertically rises and falls, and the sleeve connection design of the floating ball 2033 and the inner wall of the floating water level bin 2011 prevents water flow from seeping into the upper mechanical structure, affecting the linkage accuracy. Especially in the flood season or high-sediment water flow environment, this water diversion structure can continuously filter the water diversion, and automatically clean and intelligently control to ensure the water diversion efficiency and equipment safety.
