Description

Technical Field

[0001] The present invention relates to the technical field of drainage, in particular to a water conservancy engineering drainage system and a drainage control method. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater in order to eliminate harm and promote benefits. The construction of water conservancy projects can control water flow, prevent floods and waterlogging disasters, and regulate and allocate water to meet the people's needs for water resources in life and production.

[0003] In water-scarce areas on the plateau, it is very important to control soil erosion, improve the ecological environment, and reduce the amount of sediment entering rivers and reservoirs (lakes); at the same time, it is important to store water and conserve soil, protect arable land resources, increase regional vegetation coverage and vegetation quality, conserve water resources, and maintain ecological stability, which are very important for improving rural infrastructure conditions.

[0004] In the comprehensive management of soil and water loss in the cultivated land of Yanguanpo, Zhangyi Town, Yuanzhou District, Guyuan City, Ningxia, Yanguanpo, Zhangyi Town, Yuanzhou District, is located in the middle reaches of Malianchuan River on the left bank of the upper reaches of Hulu River. It is a loess hilly gully erosion area with an annual sediment transport of 5,000t / km2.a, which is one of the serious soil and water loss areas in Ningxia. The land reclamation rate in this area is high, and there are many sloping cultivated land and old narrow terraces. The water storage and soil conservation capacity is insufficient, and the sand production is large, which threatens the flood control safety of rivers, reduces the life of reservoirs and dams, and silts up water conservancy facilities. Moreover, there are many sloping cultivated lands, especially old narrow terraces in this area, which are not conducive to the protection of water and soil resources, nor to the development of agricultural production, especially not suitable for modern mechanized production operations, which hinders the improvement of regional agricultural labor productivity. Moreover, the imperfect production road network and irrigation and drainage facilities restrict the rural economic and social development. It is an important measure to systematically improve the rural environment to improve rural infrastructure conditions and, in accordance with the concept of comprehensive management of mountains, rivers, forests, fields, lakes, grasslands and deserts, while vigorously carrying out soil and water conservation projects such as slope conversion, tree planting and grass planting, dam construction and land reclamation to control soil erosion, combine the construction of rural infrastructure such as production roads, various small bridges and culverts, drainage ditches, slope protection, etc., to systematically improve the rural ecological environment and living environment.

[0005] In particular, for areas like Yanguanpo, Zhangyi Town, Yuanzhou District, Guyuan City, Ningxia, the regional drought makes the collection, purification and utilization of rainwater particularly important. It is necessary to build a series of water conservancy engineering systems to collect and utilize rainwater.

[0006] However, when rainwater is currently treated, it carries a lot of debris, such as leaves, tree trunks, garbage, and sand, as it passes through the road surface. If the rainwater carrying debris is directly discharged into artificial reservoirs or artificial lakes through pipes and canals, it is easy to cause pipe blockage and siltation of artificial reservoirs or artificial lakes. After a long period of accumulation, the drainage and water storage systems cannot be used normally.

[0007] Therefore, when constructing water conservancy facilities for rainwater collection and utilization, it is necessary to focus on the above-mentioned problems of pipe blockage and silt deposition.

[0008] The patent with publication number CN107893468A discloses a rainwater collection and purification filter box, including a reaction tank and a water inlet box, two support seats are provided on the top of the reaction tank, the water inlet box is erected between the two support seats, and a first motor and a second motor are provided on the two support seats respectively. A water inlet hopper is provided in the water inlet box, and an upwardly open rainwater collection trough is provided above the water inlet hopper. The device is provided with an upwardly open rainwater collection trough, which can collect rainwater in a large range, and through the setting of crushing rollers and squeezing rollers, large pieces of waste in the rainwater are broken to avoid large-volume debris clogging the water inlet, and at the same time, small particles of waste mixed in the rainwater are blocked in the debris partition box by the processing filter screen and the secondary filter screen, thereby realizing the dry and wet separation of rainwater.

[0009] Although rainwater collection and purification devices similar to the above-mentioned ones have solved the problem of breaking up large pieces of waste in rainwater to a certain extent and preventing debris from clogging the water inlet. However, rainwater purification devices like this are not suitable for the above-mentioned areas similar to Yanguanpo, Zhangyi Town, Yuanzhou District, Guyuan City, Ningxia, because such areas suffer from severe soil erosion, and the rainwater also contains a large amount of loess silt, which is very easy to deposit and clog during pipe flow. Therefore, for areas similar to Yanguanpo, Zhangyi Town, Yuanzhou District, Guyuan City, Ningxia, when constructing a rainwater collection and utilization water conservancy system similar to the above-mentioned one, in addition to considering the breaking up of debris in rainwater, it is also necessary to focus on the problem of silt deposition easily leading to blockage.

[0010] Therefore, it is necessary to invent a water conservancy project drainage system and a drainage control method to solve the above technical problems. Summary of the invention

[0025] A method for controlling a drainage system of a water conservancy project is also provided:

[0026] S1. First, the water pipe is connected to the outside world. Under the impact of water flow, the transmission plate drives the rotating shaft to rotate, and the rotating shaft drives the first cutter and the second cutter to rotate and crush, and the water pushing member pushes the water flow to the filter box;

[0027] S2. When water flows through the filter box, the baffle enables the water flow to continuously move up and down, and impurities in the water flow gradually sink into the filter box;

[0028] S3, when the pressure generated by the weight of the impurities deposited in the filter box is greater than the gravity of the balance block and the elastic force of the balance plate, the deposited impurities can be pushed into the collecting member;

[0029] S4. The water then flows out through the drain pipe.

[0030] Beneficial effects of the present invention:

[0031] 1. By setting the first cutter and the second cutter which can rotate in opposite directions, leaves, branches, garbage, etc. can be chopped up to prevent debris from clogging the inside of the device during drainage.

[0032] 2. By setting up rotatable water-pushing parts and cleaning parts, the deposited debris can be moved to prevent the garbage from settling at the bottom of the crushing tank and avoiding the deposition of garbage in the crushing tank. The water-pushing parts are spiral plates. When rotating along their spiral direction, they can quickly push the water flow into the connecting pipe. At the same time, through the cooperation of the cleaning components, the impurities mixed in the water flow are pushed into the connecting pipe, which solves the problem of not being able to quickly push the impurities and water flow out of the crushing tank, and realizes the purpose of self-adjustment and control of the drainage speed according to the water flow of the actual water flow.

[0033] 3. Since the two adjacent baffles are staggered up and down, the water will flow slowly through the other end of the first baffle close to the second baffle. As the water flow speed slows down, the sedimentation efficiency increases. As the water flow rises and falls step by step, the debris, silt, etc. in the water flow can be deposited to purify the water flow.

[0034] 4. By setting up the filter box, balance block, etc., and utilizing the principle that the density of water is less than the density of impurities, when the impurities in the filter box are deposited to a certain weight, the garbage in the filter box will be automatically discharged to avoid the filter box being blocked during long-term use, which will affect the drainage efficiency. This ensures the efficient drainage process and avoids the filter box being blocked.

[0035] 5. The balancing groove, diverter pipe, limit plate, push groove, hemispherical groove, spherical rod and second elastic member are capable of opening and closing the diverter pipe according to the situation, thereby assisting the downward movement of the balancing block, thereby ensuring that after the garbage is completely pushed out, the balancing block can be moved to the initial height to ensure the normal operation of the subsequent drainage system.

DETAILED DESCRIPTION

[0048] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0049] Example 1

[0050] At present, when rainwater is collected and reused, since rainwater carries a large amount of debris, such as branches, leaves, garbage and other debris, the existing devices are not convenient for crushing larger impurities such as leaves. When in use, it is easy to cause direct blockage of the pipeline, affecting the smooth progress of drainage operations and even leading to drainage interruption.

[0051] In order to solve the above technical problems, Figures 1 to 4 and Figures 9 to 11It can be seen that the adopted technical solution includes a roadbed 7, a concrete retaining wall 1 is arranged in the roadbed 7, a prefabricated cover plate 9 that can cover the concrete retaining wall 1 is detachably connected to the roadbed 7, a prefabricated cover plate 8 that can cover the concrete retaining wall 1 is detachably connected to the roadbed 7, and a water pipe 2 with one end extending out of the concrete retaining wall 1 is opened in the concrete retaining wall 1.

[0052] The crushing assembly 3 includes a crushing groove 301 which is arranged in the concrete retaining wall 1 and connected to the water pipe 2 at one end. A rotating shaft 302 is rotatably provided on the inner wall of the crushing groove 301. A transmission plate 303 inserted into the water pipe 2 is provided at one end of the rotating shaft 302. A first cutter 304 is provided on the end of the rotating shaft 302 away from the transmission plate 303. A transmission shaft is provided at the end of the crushing groove 301 away from the rotating shaft 302. A second cutter 305 is provided on the end of the transmission shaft close to the rotating shaft 302. The first cutter 304 and the second cutter 305 are in contact with each other. First transmission parts 306 are respectively provided on the outer sides of the first cutter 304 and the second cutter 305. A second transmission part 307 meshing with the two first transmission parts 306 is provided in the crushing groove 301.

[0053] When water is discharged into the water body through the water pipe 2, due to the height difference between the water pipe 2 and the access position, the water flow can drive the transmission plate 303 to rotate, and the transmission plate 303 drives the first cutter 304 to rotate via the rotating shaft 302, and the first cutter 304 drives the first transmission part 306 thereon to rotate, and the first transmission part 306 drives the second transmission part 307 on the second cutter 305 to rotate via the second transmission part 307, and the second cutter 305 drives the transmission shaft 308 to rotate. The two cutters rotate in opposite directions to crush the leaves and other garbage passing by, so as to prevent the leaves and other garbage from moving inside the device later and causing the internal pipeline to be blocked. A cavity is opened in the concrete retaining wall 1 to facilitate the entry of personnel, and the opening and closing of the disassembled prefabricated cover plate 9 can also be convenient for the replacement and maintenance of internal parts.

[0054] Example 2

[0055] When the crushed garbage flows inside the crushing trough 301, due to the use time of the device and the water flow rate, or the placement angle of the device when in use, the crushed leaves, mud and sand may be deposited in the crushing trough 301, resulting in poor water discharge, and even blockage in severe cases. Therefore, it is necessary to perform anti-deposition operation on the inside of the crushing trough 301.

[0056] In order to solve the above technical problems, based on Example 1, Figure 1 , Figure 2 and Figure 7It can be seen that the adopted technical solution includes an anti-deposition component 4, which includes a water pushing member 401 arranged on the rotating shaft 302, and a cleaning member 402 in contact with the inner wall of the crushing groove 301 is arranged on the water pushing member 401.

[0057] As the crushed garbage flows into the crushing trough 301 with the water flow, the garbage may be deposited due to the usage time and the water flow rate. Therefore, when the transmission shaft 308 rotates, the transmission shaft 308 drives the water pushing member 401 to rotate, and the water pushing member 401 drives the cleaning member 402 to rotate. Since the cleaning member 402 can contact the inner wall of the crushing trough 301, the deposited garbage can be moved to prevent the garbage from being deposited at the bottom of the crushing trough 301, thereby avoiding the deposition of garbage in the crushing trough 301.

[0058] Example 3

[0059] When preventing garbage from depositing, although the cleaning part 402 can be moved, it cannot guarantee that the deposited garbage can be quickly pushed out of the crushing groove 301, resulting in the water body not being released quickly, which can easily lead to the problem of increasingly turbid water and increasing impurities. Therefore, a component that can quickly push impurities and water flow is needed.

[0060] Based on the above embodiment, Figure 1 and Figure 7 It can be seen that the adopted technical solution includes an anti-deposition component 4, which includes a water pushing member 401 arranged on the rotating shaft 302, and a cleaning member 402 in contact with the inner wall of the crushing groove 301 is arranged on the water pushing member 401.

[0061] Depend on Figure 4 It can be seen that the water pushing member 401 is a spiral plate, which can quickly push the water flow into the connecting pipe 502 when rotating along its spiral direction. At the same time, through the cooperation of the cleaning component, the impurities mixed in the water flow are pushed into the connecting pipe 502, which solves the problem of not being able to quickly push the impurities and water flow into the crushing groove 301, and achieves the purpose of self-adjusting and controlling the drainage speed according to the water flow rate of the actual water flow.

[0062] Example 4

[0063] The above embodiment solves the problem of debris fragmentation in rainwater, and can effectively reduce the probability of the drainage system being blocked by debris. However, in areas similar to Yanguanpo, Zhangyi Town, Yuanzhou District, Guyuan City, Ningxia, as described in the background technology, because of the serious soil erosion in such areas, the rainwater also contains a large amount of loess silt, which is very easy to deposit and block in the pipeline flow. Because of this problem, it is also necessary to focus on the problem that silt deposition easily leads to blockage.

[0064] Based on the above embodiment, Figures 1 to 6 ,and Figures 8 to 11It can be seen that the adopted technical solution includes a filter component 5, which is arranged below the crushing trough 301. The filter component 5 includes a filter box 501. The filter box 501 and the crushing trough 301 are connected via a connecting pipe 502. A plurality of baffles 503 are fixedly provided in the filter box 501. The plurality of baffles 503 are staggeredly distributed on the upper and lower sides of the filter box 501. One end of the filter box 501 away from the crushing trough 301 is provided with a drainage pipe 504 extending out of the concrete retaining wall 1.

[0065] When the water flows through the connecting pipe 502 and is discharged into one side of the filter box 501, the water flows through the first baffle 503. The height of the water flow gradually rises under the action of the first baffle 503. As the water flows upward, impurities in the water body gradually settle into the filter box 501. Then the water flows through the unobstructed part on the upper side and enters the second baffle 503. Since the two adjacent baffles 503 are staggered, the water flow will pass through the first baffle 503 and flow slowly toward the other end face of the second baffle 503. Since the water flow speed slows down, the deposition efficiency is increased, which is more conducive to the deposition of impurities. When the water flow rises and contacts the lower end of the second baffle 503, the water flow begins to rise between the third baffle 503 and the second baffle 503 and flows out. As the water flow rises and falls step by step, the deposition of impurities is maximized. Finally, the water flows through the drain pipe 504 and is discharged into the external water body. At this time, most of the impurities have been removed from the water flow.

[0066] Example 5

[0067] Although the water body is purified when impurities are filtered, as the use time increases, more and more deposited garbage accumulates in the filter box 501, causing the filter box 501 to lose its original purification function, and even cause the filter box 501 to be blocked, making the drainage device unable to work normally, so it is necessary to quantitatively clean the deposited garbage.

[0068] Based on the above embodiment, Figures 1 to 11It can be seen that the adopted technical solution includes a cleaning component 6, which includes a pusher 601 arranged in the filter box 501, an opening is arranged at one end of the filter box 501, a cover 602 capable of covering the opening is arranged on the pusher 601, and sealing members are respectively arranged at the openings of the cover 602 and the filter box 501, a plurality of make way grooves 603 corresponding to the baffle 503 are opened on the pusher 601, a connecting member 617 is arranged on the pusher 601, a balancing block 604 located on the side away from the filter box 501 is slidably arranged in the concrete retaining wall 1, and a horizontal balancing plate 605 is rotatably arranged in the concrete retaining wall 1, and both sides of the balancing plate 605 are divided into The cleaning assembly 6 further comprises a lifting member 607 disposed in the concrete retaining wall 1, wherein the upper end of the lifting member 607 is fixedly connected to the filter box 501, and a first elastic member is disposed between the lower end of the lifting member 607 and the concrete retaining wall 1. A limiting groove is disposed in the concrete retaining wall 1, and a limiting member 608 that can be inserted into the limiting groove is slidably disposed in the concrete retaining wall 1. The limiting member 608 is provided with an inclined groove, and the lifting member 607 is provided with a plug-in 609 inserted into the inclined groove. The balance block 604 is provided with a waist-shaped A sliding column 611 is slidably arranged in the waist-shaped groove 610, a push rod 612 is fixedly arranged at one end of the sliding column 611, a connecting piece 617 is inserted into the push rod 612 and can slide in the push rod 612, a guide plate 613 is arranged in the concrete retaining wall 1, the push rod 612 is inserted into the guide plate 613 and can slide in the guide plate 613, a fixed column 614 extending in the up-down direction is arranged in the concrete retaining wall 1, the fixed column 614 penetrates the balance block 604 and is slidably connected with the balance block 604, a slide groove is opened at one end of the concrete retaining wall 1, one end of the filter box 501 is inserted into the slide groove and can move in the slide groove, and a balance groove 8 is opened on the concrete retaining wall 1, The balancing block 604 is inserted into the balancing groove 8 and can slide in the balancing groove 8. A shunt pipe 801 is provided on one side of the connecting pipe 502. One end of the shunt pipe 801 is inserted into the balancing groove 8. A limit plate 802 is slidably provided on the concrete retaining wall 1. The limit plate 802 is provided with a pushing groove 803. The upper end of the connecting piece 617 is inserted into the pushing groove 803. One end of the limit plate 802 is provided with a hemispherical groove 804. Spherical rods 805 that can be inserted into the hemispherical grooves 804 on the corresponding sides are respectively provided on both sides of the concrete retaining wall 1. A second elastic member is provided between the end of the spherical rod 805 away from the limit plate 802 and the concrete retaining wall 1, and the connecting pipe 502 can be telescopic.

[0069] As the garbage gradually settles, and because the density of mud and sand is greater than the density of water, after the mud and sand and other impurities accumulate to a certain weight, the filter box 501 gradually moves downward, and the filter box 501 drives the lifting member 607 to move downward, the first elastic member is compressed, and the lifting member 607 drives the limiting member 608 to move toward the direction close to the fixed column 614 through the inclined groove and the plug-in 609, so that the limiting member 608 gradually moves out of the limiting groove. Since the balance plate 605 is made of elastic material, when the filter box 501 moves downward, the balance plate 605 gradually deforms, and the filter box 501 can overcome the elastic force of the balance plate 605 and the gravity of the balance block 604 and move downward. The filter box 501 drives the sliding column 606 on its corresponding side to move downward, and the sliding column 606 drives one side of the balance plate 605 to deform, and one side of the balance block 604 does not change.

[0070] When the plug-in 609 moves to the other end of the inclined slot, the stopper 608 moves out of the stopper slot, and the stopper 608 is inserted into a side wall of the stopper slot, and can contact the side wall of the balance block 604, to prevent the stopper 608 from moving in the opposite direction after the balance block 604 moves upward, so that the balance block 604 cannot move downward. The filter box 501 pries the balance block 604 upward through the sliding column 606 and the balance plate 605, and because the fixed column 614 is provided, it can ensure that the balance block 604 moves vertically up and down, and the balance block 604 drives the sliding column 611 to move towards the direction of the filter box 501 through the waist-shaped groove 610, and the sliding column 611 pushes the pushing member 601 to move through the push rod 612 and the connecting member 617. The pushing member 601 pushes the impurities in the filter box 501 to move outward. The pushing member 601 simultaneously pushes the covering member 602 to move outward, and the covering member 602 drives the sealing member to move outward. Since the pushing member 601 is provided with a clearance groove 603, it can be ensured that the baffle 503 does not hinder the movement of the pushing member 601.

[0071] At the same time, during this process, after the connecting member 617 moves a certain distance in the pushing groove 803, the connecting member 617 drives the limit plate 802 to move, and the spherical rod 805 on one side moves from the hemispherical groove 804 on its corresponding side. After the spherical rod 805 no longer contacts the limit plate 802, the second elastic member drives the spherical rod 805 to move outward, and the connecting member 617 begins to push the limit plate 802 to move through the pushing groove 803, so that the limit plate 802 gradually stops squeezing the shunt pipe 801, and the other end of the limit plate 802 begins to squeeze toward the connecting pipe 502. After the connecting member 617 moves to the extreme position, the other spherical rod 805 is inserted into the hemispherical groove 804 on its corresponding side, and the limit plate 802 is not completely limited. Since the spherical rod 805 is inserted into the hemispherical groove 804 in an arc shape, it cannot be completely limited. When subjected to a large external force, the limit on the limit plate 802 can be released.

[0072] At this time, the limiting plate 802 squeezes the connecting pipe 502 and no longer squeezes the shunt pipe 801, so that the water flow begins to flow into the balancing tank 8 through the shunt pipe 801, and the water flow begins to squeeze the balancing block 604 to move downward, and the balancing block 604 drives the balancing block 604 to drive the filter box 501 to move upward via the balancing plate 605, and then under the action of the first elastic member, the lifting member 607 drives the limiting member 608 to be inserted into the limiting groove via the plug-in 609. While the balancing block 604 moves downward, the balancing block 604 drives the push rod 612 and the push member 601 to reset via the waist-shaped groove 610 and the sliding column 611, and the covering member 602 covers the filter box 501 again. Since a sealing member is provided, the sealing performance of the filter box 501 can be guaranteed, thereby solving the problem that the filter box 501 is easily blocked during the drainage process.

[0073] During the process of the balance block 604 moving the rod downward, after the connecting piece 617 contacts the other side wall of the pushing groove 803, it starts to push the limit plate 802 to move in the opposite direction, and the spherical rod 805 moves out of the hemispherical groove 804. After the limit plate 802 moves a certain distance in the opposite direction, the diverter pipe 801 is squeezed again, so that the water flow no longer flows into the balance groove 8 through the diverter pipe 801. The spherical rod 805 close to the balance block 604 is inserted into the hemispherical groove 804 on its corresponding side again to limit the limit plate 802, and the deposited impurities pushed out can be collected centrally through the collecting piece 615, which is convenient for the subsequent centralized processing of impurities. When it is necessary to remove the impurities, pull the slider 616 upward, then move the collecting piece 615 out and clean up the garbage, then put the collecting piece 615 into the concrete retaining wall 1 again, and pull the slider 616 downward to cover the collecting piece 615.

[0074] Control methods of drainage system of water conservancy projects:

[0075] S1. First, the water pipe 2 is connected to the outside world. Under the impact of the water flow, the transmission plate 303 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the first cutter 304 and the second cutter 305 to rotate and break, and the water pushing member 401 pushes the water flow to the filter box 501.

[0076] S2. When water flows through the filter box 501, the baffle 503 enables the water flow to continuously move up and down, and impurities in the water flow gradually sink into the filter box 501.

[0077] S3. When the pressure generated by the weight of the impurities deposited in the filter box 501 is greater than the gravity of the balance block 604 and the elastic force of the balance plate 605 , the deposited impurities can be pushed into the collecting member 615 .

[0078] S4. The water then flows out through the drain pipe 504.

[0079] By providing the first cutter 304 and the second cutter 305 which can rotate in opposite directions, solid waste such as leaves can be shredded to prevent the inside of the device from being blocked by impurities such as leaves during drainage. By providing the water pushing member 401 and the cleaning member 402, the deposited waste can be moved to prevent the waste from being deposited at the bottom of the crushing groove 301 and to avoid the deposition of waste in the crushing groove 301. The water pushing member 401 is a spiral plate which can quickly push the water flow into the connecting pipe 502 when rotating along its spiral direction. At the same time, the impurities mixed in the water flow can be pushed into the connecting pipe 502 through the cooperation of the cleaning component, so as to achieve the purpose of self-adjustment and control of the drainage speed according to the water flow of the real water flow, and solve the problem of not being able to quickly push the impurities and water flow into the crushing groove 30 1. Since the two adjacent baffles 503 are staggered up and down, the water will flow slowly through the other end face of the first baffle 503 close to the second baffle 503. As the water flow speed slows down, the sedimentation efficiency increases. As the water flow rises and falls step by step, the deposition of impurities is maximized. Finally, the water flows through the drain pipe 504 and is discharged into the external water body. At this time, most of the impurities have been removed from the water. Through the filter box 501, balance block 604, etc., the density of water is less than the density of impurities. When the impurities in the filter box 501 are deposited to a certain weight, the sediment in the filter box 501 is automatically discharged to avoid the filter box 501 being blocked during long-term use, which affects the drainage efficiency. The efficient drainage process is ensured to avoid the filter box 501 being blocked.
