Description

Technical Field

[0001] The invention relates to the technical field of irrigation, 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, so as to achieve the goal of eliminating harm and promoting benefits. Water is an indispensable resource in 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 disasters, 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, etc., which 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, garbage is usually piled up at the drainage outlet of the existing dam-type water conservancy engineering waterproof drainage device. 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. In addition, when draining and irrigating 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 inside of the water source during the flow, thereby causing water 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. In addition, some existing dams equipped with hydroelectric generators can only use the falling water flow to generate electricity when discharging the water source, and their power generation efficiency is low. Therefore, it does not meet the existing needs. In this regard, we propose a water conservancy engineering waterproof drainage device. Summary of the invention

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 , an embodiment provided by the present invention: a water conservancy engineering waterproof drainage device, comprising a dam body 1, a drainage cavity 3 is provided on one side of the outer surface of the dam body 1, a garbage collection mechanism 2 is provided above the drainage cavity 3, the garbage collection mechanism 2 comprises 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 are provided on the inner wall of the lower end of the garbage collection screen 209, and the rotary lifting mechanism can drive 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 forward and backward.

[0042] The garbage collection mechanism 2 further includes a control panel 215 , and the rotary lifting mechanism and the moving mechanism are 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 a second bevel gear 204, the axis of the second bevel gear 204 is connected to a threaded rod shaft 205, the lower end surface of the threaded rod shaft 205 is fixedly connected to a lifting threaded rod 206, and the upper surface of the outer surface of the lifting threaded rod 206 is connected to an internal threaded sleeve 207 through a threaded structure; the surface of the internal threaded sleeve 207 facing the garbage collecting screen 209 is fixedly installed with a large The large rotating mechanical arm 208 is fixed to the garbage collecting screen 209 on the surface thereof facing 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 more garbage inside the drainage cavity 3, first start the two large rotating mechanical arms 208 to rotate the garbage collecting screen 209, and 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 therewith 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 will move downward at this time. When the internal threaded sleeve 207 moves downward, the garbage collecting 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 completely enters the interior of the water source, the garbage collecting screen 209 is rotated counterclockwise by 90 degrees by the large rotating mechanical arm 208 to adjust it to its original angle, and then the driving shaft 202 connected thereto is driven to rotate in the opposite direction by the stepping motor 201 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 process, 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 skateboard 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 provided above the last drainage port 4 from left to right, and 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 synchronous 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, and 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 respectively located on both sides of the metal tube 16, and the top end and the bottom end of the crushing roller 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 in the process of driving the metal tube 16 to rotate;

[0049] The irrigation water purification mechanism also includes a large drainage port 5, which is located on the upper side of the rear end inner wall of the last drainage port 4 from left to right; when drainage and irrigation are performed 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 drainage ports 4 are opened to release water for irrigation;

[0050] Since the lower end surface of the metal pipe 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 pipe 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 which is connected to a waterwheel shaft 10, both ends of which 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 fixedly sleeved on the outer surface of the waterwheel shaft 10 is provided on one side of the small waterwheel 9, and the third bevel gear 11 is meshed with a fourth bevel gear 12, and the axis of the fourth bevel gear 12 is connected to a gear transmission shaft 13, and a first gear 14 is fixedly sleeved on the upper side of the outer surface of the gear transmission shaft 13, and the first gear 14 is meshed with a large gear 15 fixedly sleeved on the outer surface of the metal tube 16; the activated carbon 6 added to the inside of the large hopper 7 will enter the inside of the metal tube 16 through the inclined feed port 20 located on the upper end surface of the metal tube 16 and contact 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 therewith 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 of the metal pipe 16.

[0054] A large internal gear ring 19 fixed to the inner wall of the connecting opening 8 is provided on one side of the large gear 15, and a second gear 18 is meshed on both sides of the inner wall of the large internal gear ring 19, and the two second gears 18 are respectively fixedly sleeved 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 opening 8, the large internal gear ring 19 does not rotate with the metal tube 16 during its rotation;

[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 rotate accordingly.

[0056] The activated carbon 6 in contact with the two pulverizing rollers 17 that revolve and rotate at the same time can be pulverized to be processed into powder. The activated carbon 6 processed into powder will fall into the water source flowing inside the drain port 4 under the action of gravity, and the large drain port 5 located on the upper side of the inner wall of the rear end of the drain port 4 ensures that the water source mixed with the activated carbon 6 can be discharged to the outside, so as to prevent the water source mixed with the activated carbon 6 from being stuck between the connecting port 8 and the drain port 4 and unable to be discharged;

[0057] Activated carbon 6 can effectively adsorb harmful substances such as chlorine, chloride, heavy metal components, organic compounds, benzene compounds and phenolic substances in water due to its high porosity and large specific surface area. 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 to 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 force or electrostatic action. By adding activated carbon 6 to the water during drainage, 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 can be provided for aquatic organisms and crops. 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 the economic benefits of farmers.

[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 located in the activated carbon storage tank 5 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 revolving and rotating at the same time.

[0059] Since the water source flowing in the drain port 4 has a fast flow rate, the activated carbon 6 just 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 just 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 absorption effect of the activated carbon 6 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 used for the upper end surface of the metal tube (16) can be removed to open the inside 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, and 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 entangled with the outer surface of the small waterwheel 9. The above technical solution can ensure the normal operation of the small waterwheel 9.

[0062] Both sides of the drainage cavity 3 are provided with a dam wall scour protection power generation mechanism fixed to the outer surface of the dam body 1, and the dam wall scour protection power generation mechanism includes a shaft mounting base 21, a shaft protection plate 22, two arc-shaped tooth rows 24, two springs 25, two impeller generators 26 and a power storage box 27. The shaft protection plate 22 is connected to the shaft mounting base 21 through the shaft, and the two arc-shaped tooth rows 24 are respectively fixed to the two sides of the surface of the 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 meshed 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 installed 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 installed 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 installed 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 shaft protection plate 22 can be supported by two springs 25. When the shaft protection plate 22 rotates around the shaft mounting base 21 due to the impact of water or the impact of garbage, the springs 25 will be squeezed. When the flushing water source decreases or the garbage is bounced off due to the reaction force, the reaction force of the squeezed springs 25 can push the shaft protection plate 22 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 invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
