Abstract

The present invention relates to the field of irrigation technology, specifically to a waterproof drainage device for water conservancy projects, which solves the problem that garbage is generally accumulated at the drainage outlet of waterproof drainage devices for dam-type water conservancy projects. When the dam is opened, the accumulated garbage will be mixed with the water source and discharged together. The discharged garbage may be blocked at a certain point in the water flow, thereby affecting the flow rate of the water flow. In addition, when irrigating in areas with a high content of heavy metals in the soil, the water source may be polluted during the flow process, and the dam itself has low protective performance. The garbage collection mechanism in the present invention can collect garbage, and the irrigation water purification mechanism can add powdered activated carbon to the water flow during the flow.

Description

Technical Field

[0001] The present invention relates to the field of irrigation technology, in particular to a waterproof drainage device for a water conservancy project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater, thereby achieving the goal of eliminating harm and promoting benefits. Water is an indispensable resource for human production and life, but in most cases it does not meet human needs. Therefore, it is necessary to build water conservancy projects to control water flow, prevent floods and waterlogging, and regulate and distribute water to meet people's needs for water resources in life and production.

[0003] Water conservancy projects are often composed of several hydraulic structures with different functions, such as dams, dikes, spillways, sluices, water inlets, channels, ferries, valves and other buildings that cooperate with each other and operate in coordination to form a complex of hydraulic structures. The dams in water conservancy projects can prevent floods, protect residents and industrial and agricultural production. Some dam walls have dredging grooves and drainage grooves on their surfaces. These structures can be used to control the flow and discharge of water. This design enables the dam wall to not only intercept water sources to prevent flood disasters, but also discharge water sources according to the situation, such as agricultural irrigation or water discharge for flood control, etc. This dam that can prevent floods and discharge water sources according to demand can be called a water conservancy project waterproofing and drainage device.

[0004] However, the drainage outlets of existing dam-type water conservancy projects generally accumulate garbage. When the sluice gates are opened for irrigation by farmers, the accumulated garbage will be mixed with the water source and discharged together. The discharged garbage may be blocked at a certain point in the water flow, thereby affecting the flow rate of the water. Moreover, when drainage and irrigation are carried out in areas with a high content of heavy metals in the soil, the water source may mix the heavy metal components in the soil with the interior of the water source during the flow process, thereby polluting the water quality and affecting the production and development of crops. The dam will also intercept garbage in the process of intercepting the water source. During the long-term use of the dam, multiple collisions with large garbage may cause the surface of the dam to be damaged, thereby affecting its service life. Moreover, some existing dams equipped with hydroelectric generators can only use the falling water flow to generate electricity when discharging the water source, and its power generation efficiency is low. Therefore, it does not meet the existing needs. In this regard, we propose a water conservancy project waterproof drainage device. Summary of the Invention

[0005] The purpose of the present invention is to provide a waterproof drainage device for water conservancy projects to solve the problem proposed in the above background technology that garbage is generally accumulated at the drainage outlet of the existing waterproof drainage device of dam-type water conservancy projects. When the sluice gate is opened due to farmers' irrigation needs, the accumulated garbage will be mixed with the water source and discharged together. The discharged garbage may be blocked at a certain point in the water flow, thereby affecting the flow rate of the water flow. In addition, when drainage and irrigation are carried out in some areas with a large amount of heavy metal components in the soil, the water source may mix the heavy metal components in the soil with the interior of the water source during the flow process, thereby causing water quality pollution and affecting the production and development of crops. The dam will also intercept garbage in the process of intercepting the water source. In the long-term use of the dam, multiple collisions with large garbage may cause the surface of the dam to be damaged, thereby affecting its service life.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1.

Adding activated carbon during drainage increases the dissolved oxygen content in the water, improving the redox environment of the water body and providing more suitable growth conditions for aquatic organisms and crops. Furthermore, irrigation water treated with activated carbon can reduce the accumulation of harmful substances in crops, thereby improving the quality and safety of agricultural products. Furthermore, good water quality also helps increase the yield and quality of crops, increasing farmers' economic benefits.

[0027] 3. The present invention provides a shaft protection plate on the outside of the dam body, which is connected to the shaft mounting base through a shaft. The shaft protection plate and the metal protection plate slidably mounted on the outer surface of the shaft protection plate can prevent garbage in the water source from colliding with the outer surface of the dam body. When the shaft protection plate rotates around the shaft mounting base due to the impact of the water source or the impact of garbage, the arc-shaped tooth row fixed to it will move along with it. The moving arc-shaped tooth row can drive the impeller on the impeller-type generator meshed with it to rotate. The rotating impeller can convert kinetic energy into electrical energy to generate power. The protection of the metal protection plate and the shaft protection plate in the above technical solution can prevent garbage floating in the water source from directly colliding with the outer surface of the dam body during long-term use, thereby preventing pits or cracks on its surface due to the impact. When garbage hits the metal protection plate and causes it to rotate, it can also automatically generate power. This structure not only enhances the protection of the dam body and increases its service life, but also expands the economic efficiency it can generate. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] See also Figures 1 to 8 The present invention provides an embodiment of a water conservancy project waterproof drainage device, comprising a dam body 1, a drainage cavity 3 being provided on one side of the outer surface of the dam body 1, a garbage collection mechanism 2 being provided above the drainage cavity 3, the garbage collection mechanism 2 comprising a rotary lifting mechanism, a garbage collection screen 209, a garbage collection bin 214, and a moving mechanism, a plurality of water source openings 210 being provided on the inner wall of the lower end of the garbage collection screen 209, and the rotary lifting mechanism being capable of driving the garbage collection screen 209 to move up and down or rotate.

[0041] The garbage collection bin 214 is located at the lower side behind the garbage collection screen 209, and the moving mechanism can move the garbage collection bin 214 back and forth.

[0042] The garbage collection mechanism 2 further includes a control panel 215 , and the rotary lifting mechanism and the moving mechanism are both electrically connected to the control panel 215 ; the rotary lifting mechanism and the moving mechanism can be controlled through the garbage collection bin 214 .

[0043] A plurality of drainage ports 4 are provided on the inner wall of the drainage cavity 3 .

[0044] The rotary lifting mechanism includes a concave bracket 211, a stepper motor 201 is fixedly installed on one side of the concave bracket 211, the output shaft of the stepper motor 201 is connected to the transmission shaft 202 through a coupling, and a first bevel gear 203 is fixedly sleeved on both sides of the outer surface of the transmission shaft 202. The first bevel gear 203 is meshed with the second bevel gear 204, and the axis of the second bevel gear 204 is connected to the threaded rod shaft 205. The lower end surface of the threaded rod shaft 205 is fixedly connected to the lifting threaded rod 206, and the upper surface of the outer surface of the lifting threaded rod 206 is connected to the internal threaded sleeve 207 through a threaded structure; the internal threaded sleeve 207 is fixedly installed with a large screw threaded sleeve facing the garbage collection screen 209. The large rotating mechanical arm 208 is fixed between the surface of the large rotating mechanical arm 208 facing the garbage collecting screen 209 and the garbage collecting screen 209; when the drain outlet 4 needs to be opened due to the irrigation needs of farmers, first check whether the various devices on the dam body 1 are normal, and then observe whether there is garbage inside the drainage cavity 3. If it is found that there is a lot of garbage inside the drainage cavity 3, first start the two large rotating mechanical arms 208 to rotate the garbage collecting screen 209, then rotate the garbage collecting screen 209 clockwise by 90 degrees to adjust it to an upright state, and then start the stepper motor 201, which can drive the transmission shaft 202 connected thereto and the fixed sleeve on the transmission The first bevel gear 203 on the outer surface of the rotating shaft 202 rotates, and the rotating first bevel gear 203 can drive the second bevel gear 204 meshing with it and the lifting threaded rod 206 connected to the axis of the second bevel gear 204 to rotate. When the lifting threaded rod 206 rotates, the lifting threaded rod 206 fixed thereto will rotate together. When the lifting threaded rod 206 rotates, the internal threaded sleeve 207 threadedly connected thereto will move up and down under the drive of the threaded structure, and the internal threaded sleeve 207 moves downward. When the internal threaded sleeve 207 moves downward, the garbage collection screen 209 connected to it through the large rotating mechanical arm 208 will move downward together with it, and as it becomes upright As the garbage collecting screen 209 descends, the garbage collecting screen 209 will pass through the garbage floating in the drainage chamber 3 and enter the interior of the water source. When the garbage collecting screen 209 has completely entered the interior of the water source, the garbage collecting screen 209 is rotated 90 degrees counterclockwise by the large rotating mechanical arm 208 to adjust it to its original angle. Then, the stepping motor 201 drives the transmission shaft 202 connected thereto to rotate in the opposite direction to move the garbage collecting screen 209 upward. As the garbage collecting screen 209 rises, the garbage floating in the drainage chamber 3 will enter the interior of the garbage collecting screen 209, and the water source can be discharged through the water source port 210 located on the inner wall of the lower end of the garbage collecting screen 209.

[0045] The moving mechanism includes a slide 212, and an electric slide 213 is slidably mounted on the outer surface of the slide 212, and the upper end surface of the electric slide 213 is fixed to the lower end surface of the garbage collection bin 214; when the garbage collection screen 209 moves back to its original height, the stepper motor 201 is turned off, and then the garbage collection bin 214 fixed to the upper end surface of the electric slide 213 is moved to the bottom of the water source port 210 by the electric slide 213, and then the garbage collection screen 209 is rotated 180 degrees clockwise by the large rotating mechanical arm 208. During the rotation, the garbage collection screen 209 The garbage inside it will fall into the garbage collection bin 214 under the action of gravity. When all the garbage inside the garbage collection screen 209 falls into the garbage collection bin 214, the garbage collection bin 214 can be moved back to its original position by the electric slide 213. The above technical solution can collect the garbage inside the drainage cavity 3 before drainage and irrigation, so as to prevent the garbage accumulated inside the drainage cavity 3 from being discharged together with the water source, thereby causing the water flow rate to be affected by the garbage accumulated in one place, thereby increasing the functionality of the equipment.

[0046] An irrigation water purification mechanism is located above the last drain outlet 4 from left to right. The irrigation water purification mechanism includes activated carbon 6, a large hopper 7, a connecting port 8, a metal pipe 16, two crushing rollers 17, a water flow synchronization transmission mechanism, and an inclined feed port 20. The connecting port 8 is located in the middle of the lower end surface of the large hopper 7, and the activated carbon 6 is located inside the large hopper 7.

[0047] The metal tube 16 is installed inside the connecting port 8 through a roller bearing. The lower end surface of the metal tube 16 is higher than the upper end surface of the dam body 1. The inclined feed port 20 is located in the middle of the upper end surface of the metal tube 16. The interior of the metal tube 16 is connected to the interior of the large hopper 7 through the inclined feed port 20.

[0048] The two crushing rollers 17 are located on both sides of the metal tube 16, and the top and bottom ends of the crushing rollers 17 are connected to the metal tube 16 through roller bearings. The water flow synchronous transmission mechanism can synchronously drive the two crushing rollers 17 to rotate while driving the metal tube 16 to rotate.

[0049] The irrigation water purification mechanism also includes a large drain outlet 5, which is located on the upper side of the rear end inner wall of the last drain outlet 4 from left to right. When draining and irrigating in areas where the soil contains a large amount of heavy metals, activated carbon 6 is first added to the inside of the large hopper 7, and then all the drain outlets 4 are opened to release water for irrigation.

[0050] Since the lower end surface of the metal tube 16 is higher than the upper end surface of the upper end surface of the dam body 1, during the entire drainage and irrigation process, the water flowing inside the drain outlet 4 can be prevented from entering the large hopper 7 under the action of the communicating vessel principle, thereby causing the activated carbon 6 located inside the large hopper 7 to float on the water surface and unable to enter the metal tube 16. In addition, during the entire process of opening the valve to release water, activated carbon 6 needs to be added every other day to ensure that the discharge of activated carbon 6 can be maintained at all times during the entire water release process.

[0051] The water flow synchronous transmission mechanism includes a small waterwheel 9, the axis of the small waterwheel 9 is connected to the waterwheel rotating shaft 10, both ends of the waterwheel rotating shaft 10 are connected to a fixed bracket, and the upper end surface of the fixed bracket is fixed to the inner wall of the drain outlet 4; the small waterwheel 9 can be fixed by the fixed bracket.

[0052] A third bevel gear 11 is fixedly mounted on one side of the small waterwheel 9 and is engaged with a fourth bevel gear 12. The axis of the fourth bevel gear 12 is connected to a gear transmission shaft 13. A first gear 14 is fixedly mounted on the upper side of the outer surface of the gear transmission shaft 13. The first gear 14 is engaged with a large gear 15 fixedly mounted on the outer surface of a metal tube 16. The activated carbon 6 added to the large hopper 7 enters the interior of the metal tube 16 through the inclined feed port 20 located on the upper end surface of the metal tube 16 and contacts the two crushing rollers 17.

[0053] When the drain outlet 4 is opened and water flows inside the drain outlet 4, the water source will drive the small waterwheel 9 located inside the drain outlet 4 to rotate together. During the rotation of the small waterwheel 9, the waterwheel shaft 10 connected to the axis of the small waterwheel 9 and the third bevel gear 11 fixedly mounted on the outer surface of the waterwheel shaft 10 will rotate together. When the third bevel gear 11 rotates, the fourth bevel gear 12 meshing with it and the gear transmission shaft 13 connected to the axis of the fourth bevel gear 12 will rotate together. When the gear transmission shaft 13 rotates, the first gear 14 fixedly mounted on the outer surface of the gear transmission shaft 13 and the large gear 15 meshing with the first gear 14 will rotate synchronously. When the large gear 15 rotates, the metal pipe 16 fixed inside the large gear 15 will rotate together. When the metal pipe 16 rotates, the two crushing rollers 17 respectively installed on both sides of the metal pipe 16 will revolve around the center point inside the metal pipe 16.

[0054] One side of the large gear 15 is provided with a large internal gear ring 19 fixed to the inner wall of the connecting port 8. A second gear 18 is meshed on both sides of the inner wall of the large internal gear ring 19. The two second gears 18 are respectively fixedly mounted on the upper sides of the outer surfaces of the two crushing rollers 17. Since the large internal gear ring 19 is fixed to the inner wall of the connecting port 8, the large internal gear ring 19 does not rotate with it during the rotation of the metal tube 16.

[0055] During the rotation of the metal tube 16, the second gear 18 located inside the metal tube 16 and meshing with the large inner gear ring 19 will roll along the large inner gear ring 19. Under the transmission of the gear structure, the second gear 18 rolling along the inner wall of the large inner gear ring 19 will rotate accordingly. During the rotation of the second gear 18, the crushing roller 17 connected to the axis of the second gear 18 will also rotate accordingly.

[0056] The activated carbon 6 in contact with the activated carbon 6 is crushed by two pulverizing rollers 17 that revolve and rotate simultaneously, thereby processing the activated carbon 6 into powder. The activated carbon 6 processed into powder will fall into the water source flowing inside the drain outlet 4 under the action of gravity. The large drain outlet 5 located on the upper side of the inner wall of the rear end of the drain outlet 4 ensures that the water source mixed with the activated carbon 6 can be discharged to the outside, thereby preventing the water source mixed with the activated carbon 6 from being stuck between the connecting port 8 and the drain outlet 4 and being unable to be discharged.

[0057] Activated carbon 6, due to its high porosity and large specific surface area, can effectively adsorb harmful substances such as chlorine, chloride, heavy metal components, organic compounds, benzene compounds and phenolic substances in water. The adsorption of heavy metal ions by activated carbon is mainly achieved through chemical adsorption and physical adsorption. Chemical adsorption is the process of fixing substances on the surface of activated carbon through chemical reactions. There are some active functional groups on the surface of activated carbon, such as hydroxyl and carboxyl groups. These functional groups can react chemically with organic matter and fix the organic matter on the surface of activated carbon. Physical absorption is the adsorption of molecules or ions to the surface of activated carbon through van der Waals forces or electrostatic effects. By adding activated carbon 6 to the water during the drainage process, the dissolved oxygen content in the water can be increased, the redox environment of the water body can be improved, and more suitable growth conditions for aquatic organisms and crops can be provided. Irrigation water treated with activated carbon 6 can reduce the accumulation of harmful substances in crops, thereby improving the quality and safety of agricultural products. At the same time, good water quality also helps to increase the yield and quality of crops and increase farmers' economic benefits.

[0058] When the drain port 4 is opened to discharge irrigation water, the entire dam body 1 will vibrate slightly due to the impact of the water flow. Under the influence of this vibration, the activated carbon 6 inside the activated carbon storage tank will continuously fall from the inclined feed port 20 located on the upper end surface of the metal tube 16 into the interior of the metal tube 16 and contact the two pulverizing rollers 17 that are rotating while revolving.

[0059] Since the water source flowing in the drain outlet 4 flows at a high speed, the activated carbon 6 that has just been added to the water source may not be able to fully absorb the harmful substances in the water. These substances may pass through the activated carbon layer of the activated carbon 6 along with the water flow. Although the activated carbon 6 that has just been added to the water source may not be able to fully absorb the harmful substances in the water, as the water source flows, the water source will eventually be irrigated into the farmland. As time goes by, the water source irrigated into the farmland will gradually calm down. In the calm water source, the activated carbon 6 can have more contact time with the toxic substances in the water, thereby ensuring the activated carbon 6's absorption effect on the toxic substances.

[0060] An annular stainless steel cover plate is provided above the two crushing rollers 17 and is located on the upper end surface of the metal tube 16, and the metal tube 16 and the annular stainless steel cover plate are fixed by screws; if it is found that the activated carbon 6 has not decreased when the activated carbon 6 is added every day, and the irrigation water purification mechanism is unable to crush the activated carbon 6 and discharge it, the annular stainless steel cover plate on the upper end surface of the metal tube 16 can be removed to open the interior of the metal tube 16 and repair its internal structure. After the internal structure of the metal tube 16 is repaired, the annular stainless steel cover plate can be installed back to its original position;

[0061] The water flow synchronous transmission mechanism also includes a circular waterwheel protective shell 31. The small waterwheel 9 is located in the circular waterwheel protective shell 31. Both sides of the upper end surface of the circular waterwheel protective shell 31 are fixed to the inner wall of the drain outlet 4 by bolts, and both sides of the outer surface of the circular waterwheel protective shell 31 are provided with multiple water flow holes 32; the circular waterwheel protective shell 31 fixed to the outside of the small waterwheel 9 can prevent small garbage mixed in the water source from colliding with the small waterwheel 9 or water plants in the water source from being entangled on the outer surface of the small waterwheel 9. The above technical solution can ensure the normal operation of the small waterwheel 9.

[0062] A dam wall scour protection power generation mechanism fixed to the outer surface of the dam body 1 is provided on both sides of the drainage chamber 3. The dam wall scour protection power generation mechanism includes a rotating shaft mounting base 21, a rotating shaft protection plate 22, two arc-shaped tooth rows 24, two springs 25, two impeller-type generators 26 and a power storage box 27. The rotating shaft protection plate 22 is connected to the rotating shaft mounting base 21 via a rotating shaft. The two arc-shaped tooth rows 24 are respectively fixed to both sides of the surface of the rotating shaft protection plate 22 facing the dam body 1, and the two springs 25 are respectively sleeved on the outer surfaces of the two arc-shaped tooth rows 24.

[0063] The impellers on the two impeller generators 26 are respectively engaged with the two arc-shaped tooth rows 24, and the two impeller generators 26 are electrically connected to the power storage box 27; the dam wall scour protection power generation mechanism also includes a power transmission line 29, one end of the power transmission line 29 is connected to a power distributor 28 fixedly mounted on the outer surface of the power storage box 27, and the other end of the power transmission line 29 is connected to a power clamp 30, and the inner side of the power clamp 30 clamps a metal protective plate 23 slidably mounted on the outer surface of the shaft protective plate 22; the outer side of the dam body 1 is provided with a shaft protective plate 22 connected to the shaft mounting base 21 through a shaft, and the isolation of the shaft protective plate 22 and the metal protective plate 23 slidably mounted on the outer surface of the shaft protective plate 22 can prevent garbage in the water source from colliding with the outer surface of the dam body 1;

[0064] The two springs 25 support the shaft guard plate 22. When the shaft guard plate 22 rotates around the shaft mounting base 21 due to the impact of water or the collision of garbage, the springs 25 are compressed. When the flushing water decreases or the garbage is bounced away by the reaction force, the reaction force of the compressed springs 25 pushes the shaft guard plate 22 back to its original position.

[0065] When the shaft mounting base 21 rotates around the shaft mounting base 21 due to external force, the arc-shaped tooth row 24 fixed thereto will move along with it. The moving arc-shaped tooth row 24 can drive the impeller on the impeller generator 26 to rotate, thereby generating electricity. The protection of the metal protective plate 23 and the shaft protective plate 22 in the above technical solution can prevent garbage floating in the water source from directly hitting the outer surface of the dam body 1 during long-term use of the dam body 1, thereby causing pits or cracks on its surface due to the impact. When garbage hits the metal protective plate 23 and causes it to rotate, it can also automatically generate power. This structure not only enhances the protection of the dam body 1 and increases its service life, but also expands the economic efficiency it can generate.

[0066] The electricity generated by the impeller generator 26 will be stored inside the power storage box 27. A part of the power can be transmitted to the metal protective plate 23 slidably installed on the outer surface of the shaft protective plate 22 through the power distributor 28 installed on the outer surface of the power storage box 27 through the power transmission line 29 and the power clamp 30. By energizing the metal protective plate 23, it can be electrochemically protected, thereby increasing the service life of the metal protective plate 23 that is in contact with the water source for a long time.

[0067] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
