Description

Technical Field

[0001] The present invention relates to the technical field of water resources engineering, and in particular to a rainwater grate of a plateau-plain water resources diversion device. Background Art

[0002] Floods often originate in mountainous areas. The rainwater received by each mountain body converges into a stream and finally flows into each branch of the drainage path shared by the contiguous mountains. The falling water flow in the mountainous area cannot be artificially blocked due to its natural characteristics. Proper management of the plateau water flow is the key to the complete utilization of natural water resources by the rainwater resources project. However, for the plain area, whether its rainwater resources project can effectively receive the water volume concentrated in the plateau drainage path poses a severe test to the receiving capacity of the drainage flood ditch.

[0003] Over time, the phenomenon of "nine droughts in ten years" has rendered many drainage flood ditches lacking actual functions. Although humans are well aware of the catastrophic consequences brought about by droughts and floods caused by climate anomalies and dare not easily change the basic structure of the mountain drainage flood ditch, people have still carried out extensive tidying and decoration on the ditch walls of the mountain drainage flood ditch. This measure is mainly to obtain clearer water sources and prevent soil from being washed away by water. However, it is worth noting that people often neglect the tidying of the ditch bottom when decorating the ditch walls. Due to the soft soil quality at the ditch bottom, plants have grown and garbage has accumulated all year round. These plants and garbage have become lush and fertile under the nourishment of the mountain water.

[0004] The domestic water problem of the people at the foot of the mountain is mainly solved by the drainage flood ditch. However, this long-term lifestyle relying on the drainage flood ditch has inevitably led to the pollution of the soil in the ditch. When the mountain water flows downstream, it is directly affected by the polluted soil in the ditch.

[0005] In view of the complexity of the plateau terrain and geology and the natural flowing characteristics of the erratic instantaneous rainfall, the disaster prevention work must be rigorous and meticulous. The main task of the rainwater resources project in the plain area to continue the plateau section water resources diversion system is to avoid disaster accidents caused by the water flow pattern changed by the terrain change.

DETAILED DESCRIPTION

[0066] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0068] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] It should also be noted that the following specific embodiments or specific implementations are a series of optimized settings listed in the present invention to further explain the specific content of the invention, and these settings can be combined or used in association with each other.

[0070] like Figures 1 - 3 The figure shows a water resource diversion device disclosed in the prior art, comprising: a flood discharge ditch 1, downstream rainwater 2, a sidewalk 3, a highway 4, an original domestic sewage pipe 5, ditch-side land 6, and a permeable grate 7. The flood discharge ditch 1 is directly connected to the downstream rainwater 2 originating from the plateau path. During operation, the flood discharge ditch 1 maintains a constant cross-section and capacity to ensure smooth reception and guidance of the plateau potential energy flow. If the flow of the downstream rainwater 2 is small, when it reaches the flood discharge ditch 1 in the plain section, the water flow may be rapidly reduced due to absorption by the soil and plants at the bottom of the ditch, and its existence may even be difficult to detect. However, if the flow of the downstream rainwater 2 surges to a disaster level, due to the lack of shape adjustment in the ditch design, and the natural slowdown of the flow rate when the high mountain potential energy flow is converted into horizontal flow, the excessive downstream rainwater 2 will cause serious overflow at the junction of the plateau discharge path and the flood discharge ditch 1 in the plain, directly eroding the environment under the land slope, causing a serious disaster and causing serious losses.

[0071] Example 1

[0072] In order to solve the problems existing in the water resource diversion device in the prior art, the present application discloses a plateau-plain water resource diversion device.

[0073] Mountains are the ideal natural reservoir for water accumulation. When mountain water flows through the mountains, its velocity naturally slows down where the foot of the mountain meets the plain. This initial slowdown causes the subsequent mountain water to gradually accumulate on the plain, forming an ever-expanding floodplain. If the floodplain is not promptly managed, the continuous mountain water will accumulate at the junction of the plain and the mountain, eventually causing a flood. The water, driven by the terrain, will continue to spread until it becomes uncontrollable.

[0074] In drought years, if rainwater from the mountains is not properly collected, this slow-flowing, limited mountain water will be quickly absorbed by the soil and plants in the gullies, ultimately disappearing without a trace due to evaporation from the surrounding climate. In rainwater resource projects, water diversion devices in plains and plateaus should follow the laws of natural water flow to ensure efficient water resource utilization and environmental protection.

[0075] like Figures 4 - 8 20-21 show a plateau-plain water resource diversion device disclosed in the present application, including a flood discharge ditch 1, a pebble pit 11, a grate 12, a rainwater water supply pipe 9, a sewage water supply pipe 10, a water diversion baffle 50, a water receiving gate 14, a switch door chamber 15 and a pipe mouth 16; the grate 12 includes a first grate 12a and a second grate 12b; the flood discharge ditch 1 is an expanded structure; the rainwater water supply pipe 9 is arranged above the sewage water supply pipe 10; a pebble pit 11 is provided at the entrance of the sewage water supply pipe 10, and a plurality of pebbles 13 are provided in the pebble pit; the first grate 12a is provided at the edge of the pebble pit to limit the entry of pebbles 13 and impurities in the water body The rainwater conveying pipe 9 and the sewage conveying pipe 10 are arranged in the water receiving gate 14; the water receiving gate 14 is arranged on the mesh, and its position height corresponds to the rainwater conveying pipe 9; the water diversion baffle 50 is a detachable central empty triangular enclosure, which is used to introduce water into the pebble pits 11 on both sides and into the rainwater conveying pipe 9 and the sewage conveying pipe 10; the inlet ends of the rainwater conveying pipe 9 and the sewage conveying pipe 10 are pipe openings 16; a switch door chamber 15 is provided between the rainwater conveying pipe 9 and the water receiving gate 14; the water receiving gate 14 is arranged on the side wall of the switch door chamber 15 through a hinge 21; the water receiving gate 14 is provided with a switch door rope pull hole 37 and a door lock ring 23.

[0076] The installation of the water diversion baffle 50 is intended to effectively address flooding and drought issues for this project system. For flooding and drought situations without potential energy flow, it is sufficient to ensure that the rainwater conveyance pipe 9 faces the flowing water, allowing water to flow naturally into the pipe. However, when dealing with natural forces such as flooding and wind, comprehensive and detailed consideration of various factors is necessary to avoid more catastrophic accidents caused by improper design. The newly installed rainwater conveyance pipe 9 on both sides of the flood discharge ditch 1 is designed to receive water falling from the expanded plain area and to cope with the flowing water in the alpine environment, which carries a variety of environmental substances and potential energy. Due to the characteristics of potential energy flow, flowing materials are most entrained and flow slower on the sides of the water surface, while they are less entrained and flow faster in the middle of the water surface. Given the principle that "clearer water, better flow properties," the rainwater conveyance pipe 9 cannot simply wait to collect rainwater on limited rainy days. If insufficient water is collected due to weather or other factors, the internal environment of the pipe may be damaged. Therefore, a pebble pit 11 is installed at the bottom of the flood discharge ditch 1, just ahead of the water collection gate 14 of the rainwater supply pipe 9. Downstream floodwaters are difficult to intercept directly due to their potential energy, but pebbles 13 placed within the pit cause the water to collide with the pebbles and flow into the pit first. Only when the water volume in the pit reaches a certain level will a horizontal flow form and flow toward the flood collection gate 14. The hinges 21 of the flood collection gate 14 are mounted on the sidewalls of the opening and closing chamber 15. Two opening and closing rope holes 37 are located above and below the door surface of the flood collection gate 14, respectively, to facilitate balanced opening and closing of the door using ropes. Furthermore, locking rings 23 are installed on the upper and lower side frames of the door to ensure a secure lock. These pebbles 13 not only help the flood collection gate 14 reduce the impact of the water flow but also work together with the mesh grating 12 to retain debris carried by the downstream rainwater 2 within the newly reserved space in the flood discharge ditch 1, thereby naturally reducing the volume of subsequent water flow and preventing further water pollution. This design helps reduce the difficulty of water pollution control and environmental protection. When the water level is low, a water diversion baffle 50 is installed to allow all water to enter the rainwater conveyance pipe 9 and the sewage conveyance pipe 10. This can prevent the water from volatilizing or entering the soil during water transportation, which is beneficial for water collection. When the water level is high, the water diversion baffle 50 is removed, allowing the water to be discharged from the central flood discharge ditch 1. The main function of the water baffle 50 is to block the ditch cross-section directly opposite the original flood discharge ditch 1, limiting its capacity. At the same time, the newly widened rainwater conveyance pipes 9 on both sides can naturally slow down, receive, and respond to problems such as sudden flooding. When floodwater flows to the expanded area, its flow rate will naturally slow down, and then it will pass through the pebble pit 11 and mesh sieve 12 for filtration before entering the rainwater conveyance pipe 9. The rainwater 2 flowing down from the mountain environment is regulated and sorted by the facilities and equipment in this project system, maintaining high quality, and then smoothly entering the subsequent water supply project, ensuring that no unexpected situations will occur. The entire process not only ensures the stability and safety of water flow, but also delivers high-quality water to areas in need, ensuring a long-term water supply.

[0077] With the above technical solutions, the present invention has the following beneficial effects: (1) By setting pebble pits and grid grates, this technical solution can effectively collect the water volume falling in the plain expansion area and filter out the impurities in the water body, improving the collection efficiency and cleanliness of water resources. (2) By introducing water diversion baffles, this technical solution can flexibly control the flow direction and flow rate of water. It can ensure that all the water body enters the water conveyance pipeline when the water potential is small, avoiding water evaporation or loss, and can also drain away excess flood water by removing the water diversion baffles when the water potential is large, enhancing the ability to cope with sudden flood water volume. (3) The design of the expanded flood discharge ditch structure and pebble pits effectively reduces the flow velocity of flood water. At the same time, by using the filtering effect of pebbles and grid grates, the impurities in the water flow are reduced, optimizing the water flow structure and ensuring the smooth progress of the subsequent water conveyance project. (4) The design of the water collection gate, especially the setting of the rope pulling hole for opening and closing the gate and the locking ring, enables the gate to open and close automatically without manual operation, ensuring the flexibility and safety of system operation. At the same time, this design avoids the need to quickly close or open the water collection gate during maintenance or in case of emergency. (5) Through the filtering effect of pebble pits and grid grates, and the separate design of the rainwater conveyance pipeline and the sewage conveyance pipeline, this technical solution can ensure the quality of the collected water resources, reduce the difficulty of subsequent water pollution treatment, and is beneficial to environmental protection and the sustainable utilization of water resources. (6) By introducing various structures and devices, such as water diversion baffles, pebble pits, grid grates, etc., this technical solution enhances the natural adaptability and reliability of the system, enabling it to cope with water flow changes under different environmental conditions and ensuring the stable operation of the system.

[0078] Such as Figure 8 , 9 , 19 is a further implementation manner of the present application, and further includes a water filter plate 18, a floating object lifting chamber 19, a blocking plate 48 and a two-chamber partition 17; a water filter plate 18 is further provided on the first grid grate 12a corresponding to the height position of the sewage conveyance pipeline 10; a floating object lifting chamber 19 is provided between the water filter plate 18 and the sewage conveyance pipeline 10; the floating object lifting chamber 19 and the switch door chamber 15 are separated by the two-chamber partition 17; a blocking plate 48 and a second grid grate 12b are provided on one side of the floating object lifting chamber 19 close to the sewage conveyance pipeline 10; the blocking plate 48 is arranged below the second grid grate 12b; a drain hole 49 is provided on the blocking plate 48.

[0079] A grid grate 12 is arranged on the water surface of the pebble pit 11, and immediately after that, a water filtering plate 18 is provided to further filter the water quality and gravity. After the water filtering plate 18, a floating object lifting chamber 19 is provided, the rear wall of which is composed of a blocking plate 48, and behind the blocking plate 48 is a newly installed sewage water conveyance pipeline 10. There are two drainage holes 49 at the lower end of the blocking plate 48, and a section of permeable second grid grate 12b is installed at the upper end of the blocking plate 48. The blocking plate 48 controls the lifting of the floating plate 32 in the floating object lifting chamber 19. The top plate of the floating object lifting chamber 19 is separated by a two-chamber partition plate 17. For the downstream rainwater 2, it first flows to the water receiving gate 14. The water receiving gate 14 utilizes the natural hydraulic action to open the gate body towards the pipeline direction. Outside the water receiving gate 14, a grid grate 12 is also provided, which not only protects the gate body but also plays a role in filtering water. In this way, the volume and potential energy of the rainwater entering the rainwater conveyance pipeline 9 are both reduced, thereby accelerating the flow rate and reducing the destructiveness, ensuring the long-term and stable operation of the water receiving gate 14. In order to make the square water receiving gate 14 match the circular rainwater conveyance pipeline 9, a switch gate chamber 15 is provided in front of the rainwater conveyance pipeline 9. The bottom plate of this chamber is the top plate of the floating object lifting chamber 19 and is separated by a two-chamber partition plate 17. The water receiving gate 14 is installed on the side wall of the switch gate chamber 15 through a hinge 21, and a locking ring 23 is provided to prevent the wind from damaging the water receiving gate 14. It is worth mentioning that the pebbles 13 in the pebble pit 11 are an excellent natural water filtering raw material. After being filtered by the pebbles 13, the downstream rainwater 2 directly enters the floating object lifting chamber 19, providing a high-quality water source for the subsequent water conveyance work.

[0080] Adopting the above technical solution, the present invention has the following beneficial effects: (1) By arranging a water filtering plate and a floating object lifting chamber in front of the sewage water conveyance pipeline, combined with the use of the pebble pit and the grid grate, this technical solution can effectively filter out impurities and floating objects in the water body, significantly improving the cleanliness of the water quality and providing a high-quality water source for the subsequent water conveyance project. (2) The design of the floating object lifting chamber, combined with the configuration of the blocking plate and the drainage holes, can flexibly regulate the water flow, ensuring that the system can operate stably and efficiently under different water potentials. This design is especially suitable for the complex and changeable hydrological environment in the plateau-plain area. (3) The grid grate arranged outside the water receiving gate not only plays a role in filtering water but also protects the water receiving gate from the impact of sundries in the water flow, extending the service life of the water receiving gate. At the same time, the installation of the hinge and the design of the locking ring also enhance the stability of the water receiving gate, further preventing the damage of natural factors such as wind to the water receiving gate. (4) By reasonably arranging each component, this technical solution optimizes the water flow structure, enabling the water flow to flow smoothly and steadily in the system, reducing the impact force and destructiveness of the water flow, and ensuring the stable operation of the entire system.

[0081] Such as Figure 9 、 10, 12-16, and 42 show a further embodiment of the present application, which further includes a floating plate 32, a spring 30, a barbed hook 41, an unlocking rope 39, and a rod body; the rod body includes: a hook-removing rod 26, a hook-locking rod 27, a closing rope rod 28a, an opening rope rod 31, and a spring-stabilizing rod 29; there are two opening rope rods 31, namely a first opening rope rod 31a and a second opening rope rod 31b; the second closing rope 20b on the same floating plate 32 combines functions with the closing rope rod 28a and the first closing rope 20a tied to the rod and has the same moving distance; the floating plate 32 is arranged in the floating object lifting chamber 19; the hook-removing rod 26, the hook-locking rod 27, the closing rope rod 28a, the second closing rope 20b, the opening rope rod 31, and the spring-stabilizing rod 29 are arranged on the floating plate 32; a spring 30 is sleeved on the spring-stabilizing rod 29; a hook 41 is arranged at the end of the hook-locking rod 27; the end of the hook-removing rod 26 is connected to the hook 41 through an unlocking rope 39; perforations corresponding to the rod body and the ropes are arranged on the two-chamber partition 17; the perforations include: a hook-removing rod perforation 36, a hook-locking rod perforation 38, a closing rope hole 34, an opening rope hole 33, and a spring-stabilizing rod perforation 35, which are respectively used for the hook-removing rod 26, the hook-locking rod 27, the closing rope rod 28a, the second closing rope 20b, the opening rope rod 31, and the spring-stabilizing rod 29 to pass through; there are two opening rope holes 33, namely a first opening rope hole 33a and a second opening rope hole 33b; the first opening rope rod 31a passes through the first opening rope hole 33a; the second opening rope rod 31b passes through the second opening rope hole 33b; there are two closing rope holes 34, namely a first closing rope hole 34a and a second closing rope hole 34b; the closing rope rod 28a passes through the first closing rope hole 34a; the second closing rope 20b passes through the second closing rope hole 34b; hollow screws 42 are arranged on each perforation of the two-chamber partition 17; nuts 43 are arranged at both ends of the hollow screws 42 for fixing the hollow screws 42 on the two-chamber partition 17; plastic film sleeve bags 44 are also arranged on all the rod bodies, and the plastic film sleeve bag 44 passing through the second closing rope hole 34b and sleeved on the second closing rope 20b is tied together with a binding rope 45.

[0082] At two diagonal positions of the floating plate 32, the structural components for opening and closing the door are mainly arranged. Specifically, at one corner of the plate, a hook release rod 26, a locking hook rod 27, and a door closing rope rod 28a are installed; while at the opposite corner of the other side of the plate, two door opening rope rods 31 are assembled. In addition, at the other two diagonal positions of the floating plate 32, the structural components for balancing the force of the floating plate are arranged. Specifically, at one corner of the plate, a stabilizer spring rod 29 is provided, and a spring 30 is sleeved outside the stabilizer spring rod 29; while at the opposite corner, a second door closing rope 20b and a stabilizer spring rod 29 are installed, and similarly, the spring 30 is also sleeved outside the stabilizer spring rod 29. The upper ends of the rod heads of the hook release rod 26, the door closing rope rod 28a, and the door opening rope rod 31 are respectively tied with the required pull ropes for easy operation and control. It should be noted that the rod head of the locking hook rod 27 is not tied with a pull rope but is directly connected to an inverted hook locking hook 41 to ensure the stability of locking. In particular, the rod head of the hook release rod 26 is not only tied with a lock release rope 39, but the other end of the lock release rope 39 is also connected to the locking hook 41, which makes the unlocking process more convenient and safe. To sum up, the floating plate 32, as the core component of the engineering system in this case, its structural design and functional configuration both reflect a high degree of professionalism and practicality, ensuring the efficient operation and stability of the entire system. The two-chamber partition 17, as the top plate of the floating object lifting chamber 19 and the bottom plate of the door opening and closing chamber 15, is fixed to the upper end of the floating plate 32. The floating rods and the second door closing rope 20b on the floating plate 32 can only move up and down. To optimize the straightening and stability performance of the floating rods, corresponding perforation structures are provided on the two-chamber partition 17, and these perforations are the best matching design to ensure the smooth operation of the floating rods. At one diagonal side of the two-chamber partition 17, there are a hook release rod perforation 36, a locking hook rod perforation 38, and a first door closing rope hole 34a. On the opposite side corner of the other side of the plate, two door opening rope holes 33 are arranged side by side. In addition, at one side corner of the other two diagonals, a stabilizer spring rod perforation 35 is configured, and at the opposite corner, there is a second door closing rope hole 34b and another stabilizer spring rod perforation 35. Each perforation on the two-chamber partition 17 is equipped with such as Figure 13 and 16The hollow screw 42 shown has nuts 43 that can be tightened at both ends of each hollow screw 42. These perforations correspond one-to-one with the respective floating rods and ropes on the floating plate 32, and the floating rods can move freely up and down in the hollow screws 42. As the bottom plate of the switch door chamber 15, the two chamber partitions 17 bear the impact and washing of the less clear and turbid water in the filtering environment. To prevent impurities in the water from depositing and jamming the floating rods and ropes that need to move, we have taken the following measures: First, each rod is wrapped with a plastic film sleeve bag 44, and then one side of the bag mouth of the plastic film sleeve bag 44 is tightly bound to the head of each rod with a binding rope 45, or the pull rope tied to the connecting rod is also tied tightly together; then, the remaining bag mouth of the plastic film sleeve bag 44 is put on the hollow screw 42 of the two chamber partitions 17, and the nut 43 is used to tightly fix the bag mouth of the plastic film sleeve bag 44 to the hollow screw 42. Similarly, the rods and ropes under the two chamber partitions 17 can also be sleeved with plastic film sleeve bags and tightly fixed in the same way. This design ensures that when the floating rods and ropes move in the plastic film sleeve bag 44, they will not be affected adversely by the turbid water. The floating plate 32 has significant balanced buoyancy characteristics. However, in the structural design, the force is applied only through two diagonals of the floating plate 32, and the remaining two diagonals do not bear the force. Without the need for additional force application, by installing a balance device, namely the stabilizing spring rod 29, on the diagonals of the floating plate 32, the stability of the floating plate is ensured. The stabilizing spring rod 29 is covered with a spring 30, and this spring enables the stabilizing spring rod 29 to move synchronously with other floating rods according to the magnitude of the force, thereby achieving the four-corner balance of the floating plate 32 during the rising and falling processes. This design ensures that all types of floating rods and ropes can operate naturally and stably during work.

[0083] Adopting the above technical solutions, the present invention has the following beneficial effects: (1) Through the rod and rope structure and the supporting perforation system, the movement of the floating plate can be precisely controlled. The rods include the unloading hook rod, the locking hook rod, the door-closing rope rod, the door-opening rope rod, and the stabilizing spring rod, which are fixed on the two chamber partitions by hollow screws and nuts, ensuring that the floating plate moves stably and smoothly up and down. (2) The design of the stabilizing spring rod in cooperation with the spring provides an additional balancing force for the floating plate, ensuring the four-corner balance of the floating plate during the rising and falling processes, and effectively preventing system instability or damage caused by uneven force. (3) Wrapping each rod and rope with a plastic film sleeve bag not only protects the rods and ropes from the influence of water quality but also facilitates the cleaning and maintenance of the system.

[0084] As Figure 9 , 10, Figures 17 and 18 show further embodiments of the present application. The top of the door opening / closing chamber 15 is the top 46 of the door opening / closing chamber, and its side wall is the side wall 47 of the door opening / closing chamber; three hanging rope loops 24 are installed on the top 46 of the door opening / closing chamber; the positions of the three hanging rope loops 24 are respectively vertically corresponding to the positions of the first door opening rope hole 33a, the first door closing rope hole 34a, and the unhooking rod perforation 36 on the chamber partition 17; a stabilizing rope loop 25 is provided on the side wall 47 of the door opening / closing chamber.

[0085] On the top 46 of the door opening / closing chamber, hanging rope loops 24 are installed. This is to prevent the impact of incoming pipe floods on the ropes and ensure that the working efficiency of the ropes is not affected. Specifically, one hanging rope loop 24 on the top 46 needs to be installed vertically corresponding to one door opening rope hole 33 on the two-chamber partition 17; at the same time, another hanging rope loop 24 also needs to be vertically corresponding to the first door closing rope hole 34a on the partition 17; and another hanging rope loop 24 needs to be vertically corresponding to the unhooking rod perforation 36. Regarding the position layout of the stabilizing rope loop 25 on the side wall 47 of the door opening / closing chamber, the working efficiency of the project system mainly depends on the energy buoyancy provided by the floating plate 32, the rigid directional movement of each floating rod, and the structural transmission function of the ropes. The locking rope loop 23 installed at the edge of the door side frame, due to the soft characteristics of the ropes, when the locking hook 41 autonomously confirms the position of the locking rope loop 23, it needs the assistance of the stabilizing rope loop 25 to ensure that the locking hook 41 can accurately penetrate into the locking rope loop 23. Therefore, the stabilizing rope loop 25 must be installed at the upper end of the unhooking rod hole 36 and also needs the additional support of the hanging rope loops 24 on the top 46 of the door opening / closing chamber.

[0086] As Figures 9 - 13 , Figures show further embodiments of the present application. There are two switch door rope pulling holes 37, which are respectively arranged at the upper and lower ends of the water collecting door 14; a first door opening rope 22a and a second door opening rope 22b are respectively tied to the first door opening rope rod 31a and the second door opening rope rod 31b; a rope pressing ring 40 is arranged beside each door opening rope hole 33.

[0087] The first door-opening rope 22a and the second door-opening rope 22b pass through two pressure rope loops 40 respectively; the first door-opening rope 22a passes through the hanging rope loop 24 installed on the top 46 of the door-opening chamber corresponding to the first door-opening rope hole 33a, and continues to pass through the door-opening rope pulling hole 37 at the upper end of the water-collecting door 14 and is fixedly connected to the door-opening rope pulling hole 37; the second door-opening rope 22b passes through the door-opening rope pulling hole 37 at the lower end of the water-collecting door 14 and is fixedly connected to the door-opening rope pulling hole 37; a pressure rope loop 40 is provided next to the first door-closing rope hole 34a; the door-closing rope rod 28a is fastened with the first door-closing rope 20a; the second door-closing rope A closing rope 20a passes through the rope loop 24 corresponding to the first closing rope hole 34a, then through the opening and closing rope hole 37 at the upper end of the water collection gate 14, where it is securely connected. A second closing rope 20b, also on the floating plate 32, functions in conjunction with the closing rope rod 28a and the first closing rope 20a attached thereto, and travels the same distance. The second closing rope 20b passes upward through the second closing rope hole 34b, then through the pressure rope loop 40 next to the first closing rope hole 34a, and then through the opening and closing rope hole 37 at the lower end of the water collection gate 14, where it is securely connected. Before the implementation of the proposed engineering system, the flood discharge ditch 1 receives floodwater from the plateau, maintaining a constant area and capacity, and transports it to the plains. During this process, the flood discharge ditch 1 can only change its flow rate, allowing water exceeding the ditch's capacity to overflow and flow freely into the land environment outside the ditch. However, the introduction of this engineering system has transformed the plain flood discharge ditch 1, particularly at the point where it receives water from the plateau, achieving timely and effective control over changes in flow rate and the amount of water flowing out of the area. As long as the water does not overflow the ditch, this valuable opportunistic water resource can be effectively retained. Due to the characteristics of potential energy flow, as water flows downward, it carries more material on both sides and flows more slowly, while the center carries less material and flows more quickly. Based on the principle that "clearer water, better flow properties," when water reaches the pebble pit 11, it inevitably flows into the pit. The pebbles 13 in the pit act as a filter, conveying the filtered clean water directly to the float elevator 19. The stable water level in the float elevator 19 ensures the smooth rise of the float plate 32. The rising movement of the float plate 32 in turn drives the synchronous rise of all the float rods and rope structures installed on it. To ensure the stable operation of the various float rods on the float plate 32, the rod heads are carefully designed to fit neatly through the perforations in the two chamber partitions 17. This design ensures that the floating rods and ropes will not jam when they move up and down within the door opening and closing chamber 15. The two door-opening rope rods 31 pass through two door-opening rope holes 33, each with a first door-opening rope 22a and a second door-opening rope 22b attached to it. A rope pressure ring 40 is provided next to the door-opening rope holes 33, through which the first and second door-opening ropes 22a, 22b must pass.Among them, the first door-opening rope 22a passes upward through the hanging rope loop 24 and terminates in the door-opening rope pulling hole 37 at the upper end of the water collecting door 14 surface; the second door-opening rope 22b passes through the rope pressing loop 40 and then directly penetrates into the door-opening rope pulling hole 37 at the lower end of the water collecting door 14 surface, and also terminates at the pulling hole. Under the action of the rope pressing loop 40, the originally same-lifting and loose-opening door-opening ropes become in a tightened state under the action of the rope pressing force. Under the tightening forces of the upper and lower two door-opening ropes, the water collecting door 14 can be smoothly opened during the rotation of the hinge 21. Through careful design and optimization of the whole system, the effective management and utilization of flood resources are realized. The closing rope rod 28a passes through the first closing rope hole 34a and is tied with the first closing rope 20a. The first closing rope 20a passes vertically upward through the corresponding hanging rope loop 24, and this hanging rope loop 24 is installed on the top 46 of the door-opening and closing chamber. Subsequently, this first closing rope 20a continues to directly pass through the door-opening rope pulling hole 37 at the upper end of the water collecting door 14 surface and is fixed and terminated at this hole. The second closing rope 20b passes through the second closing rope hole 34b and then penetrates into the rope pressing loop 40 located beside the first closing rope hole 34a, then directly passes through the door-opening rope pulling hole 37 at the lower end of the water collecting door 14 surface, and is also fixed and terminated at the hole. When the floating plate 32 rises, the closing rope rod 28a and the second closing rope 20b rise simultaneously, and the pulling forces of the first closing rope 20a and the second closing rope 20b are completely relaxed; while when the floating plate 32 descends, the closing rope rod 28a and the second closing rope 20b descend simultaneously, and the pulling forces of the first closing rope 20a and the second closing rope 20b are directly applied. Under the rotational action of the hinge 21, the water collecting door 14 closes accordingly. This opening and closing process is realized through the alternating relaxation and tension of the door-opening rope and the closing rope 20, that is, when one rope is relaxed, the other rope is tightened, and vice versa, so as to control the opening and closing of the water collecting door 14.

[0088] Adopting the above technical solution, the present invention has the following beneficial effects: (1) By installing hanging rope loops and steady rope loops on the top and side walls of the door-opening and closing chamber, the impact of incoming pipe floods on the ropes is effectively prevented, the working efficiency of the ropes is improved, and thus the stability of the whole system is enhanced. (2) Through the carefully designed floating rod structure and rope layout, combined with the use of the rope pressing loop, the smooth opening and closing of the water collecting door are realized, and the operation convenience is improved.

[0089] Such as Figures 9 - 18The following shows a further implementation of the present application. A first locking hook 41a with a downward-facing hook body is provided at the end of the locking hook rod 27. In the initial state, the first locking hook 41a hooks downward onto the locking ring 23 at the lower end of the water collecting door 14. After the floating plate 32 rises, the first locking hook 41a disengages from the locking ring 23. A unlocking rope 39 is tied to the end of the unlocking hook rod 26. The end of the unlocking rope 39 away from the unlocking hook rod 26 is tied to a second locking hook 41b with an upward-facing hook body. The unlocking rope 39 is arranged within the stabilizing rope loop 25 and the suspension rope loop 24. In the initial state, the second locking hook 41b hooks upward into the locking ring 23 at the upper end of the water collecting door 14. After the floating plate 32 rises, the unlocking hook rod 26 rises accordingly, causing the unlocking rope 39 to slacken, so that the second locking hook 41b falls by its own weight and disengages from the locking ring 23.

[0090] For a rotating switch door installed in a natural environment, it is particularly important to install a wind resistance device. The edge of the door frame of the water collecting door 14 is equipped with a locking ring 23. According to the design concept of the natural method to avoid natural disasters adopted by the engineering system of this project, the opening and closing operations of the water collecting door 14 also follow the natural principle. The core operation is that the entire system is built on the whole floating plate 32, through forward and reverse movement operations, and precisely controlling the time allocation of the program steps. The water first enters the pebble pit 11 to ensure that the floating object lifting chamber 19 receives the water source first. The locking hook rod 27 is an upright floating rod that passes through the locking hook rod hole 38 of the partition 17 between the two chambers on the floating plate 32. The rod head of the locking hook rod 27 is connected to a locking hook 41 with a downward-facing hook body, and this locking hook 41 can hook downward onto the locking ring 23 at the lower end of the frame of the water collecting door 14. Once the floating plate 32 rises slightly, the downward locking hook 41 can quickly disengage from the locking ring 23 and continue to rise with the floating plate 32. It is not until the floating plate 32 falls back close to the bottom of the floating object lifting chamber 19 that the locking hook 41 with a downward-facing hook body will penetrate into the locking ring 23 again to lock the water collecting door 14. Another unlocking hook rod 26 is also installed on the floating plate 32, and it passes through the unlocking hook rod hole 36 on the partition 17 between the two chambers. A unlocking rope 39 is tied to the rod head of the unlocking hook rod 26, and the other end of the unlocking rope 39 is connected to a locking hook 41 with an upward-facing hook body. The unlocking rope 39 is arranged in accordance with Figure 18 and Figure 17As indicated, it is arranged within the steady rope loops 25 and the suspension rope loops 24 on the side wall 47 and the top 46 of the switch door chamber. When the floating plate 32 rises, the hook release rod 26 rises accordingly, causing the lock release rope 39 to slacken, so that the lock hook 41 drops due to its own weight and disengages from the door locking loop 23. When the floating plate 32 falls back to near the bottom of the floating object lifting chamber 19, the lock hook 41 will be lifted by the lock release rope 39 and penetrate into the door locking loop 23 again, realizing the locking of the water collecting door 14. This engineering system ingeniously utilizes the phenomenon that water first enters the pebble pit and then flows smoothly, providing protection for the water collecting door 14 against flood impact damage. After being filtered by the pebbles 13 in the pebble pit 11, the water quality of the flood becomes more stable and its quality is improved. This design not only provides an appropriate path for the water flow, but also ensures the precise execution of the sequence and steps of the movement of each structure in the system, thus ensuring the stable operation of the entire system.

[0091] Adopting the above technical solution, the present invention has the following beneficial effects: (1) The technical solution drives the floating plate to rise and fall through the natural phenomenon that water enters the pebble pit and flows smoothly, and then controls the opening and closing of the water collecting door. This design enables the system to efficiently respond to environmental changes, without the need for an external power source, achieving the natural utilization of resources and energy conservation and emission reduction. (2) Through the design of the lock hook rod and the hook release rod, combined with the movement of the floating plate, reliable locking and unlocking of the water collecting door are achieved. This design not only ensures the stability of the water collecting door under flood impact, but also can automatically return to the locked state after the flood recedes, providing an effective protection mechanism for the system. (3) In the technical solution, through the carefully designed structural layout and the time allocation control program steps, the sequence of movement of each structure in the system and the precise execution of the steps are ensured. This not only improves the operating efficiency of the system, but also guarantees the stability and reliability of the system. (4) Utilize the natural forces of water flow and buoyancy to realize the self-opening and self-closing operation of the water collecting door, avoiding the environmental pollution and energy consumption that may be brought by traditional mechanical drive. (5) This technical solution has the ability to intelligently adapt to environmental changes, and can automatically adjust the opening and closing degree of the water collecting door according to the water level and flow rate of the flood. After the flood recedes, the system can automatically return to the initial state, preparing for the next flood response. This automatic recovery function reduces the need for manual intervention and improves the intelligent level of the system.

[0092] As Figure 8 、 19 As shown in the preferred embodiment of the present application, the total area of the drain holes 49 is smaller than the total area of the water inlet of the water filter plate 18.

[0093] In the engineering system of this application, the function of the original flood discharge ditch 1 has been locally transformed. The position of the sewage water conveyance pipeline 10 happens to be at the same horizontal plane as the floating object lifting chamber 19. To solve the problem of the descent of the floating plate 32 in the floating object lifting chamber 19, two drainage holes 49 are opened below the isolation plug plate 48 between the sewage water conveyance pipeline 10 and the floating object lifting chamber 19. The total area of these two drainage holes 49 is smaller than the total water inlet area of the water filtering plate 18, thereby ensuring that the rising ability and energy of the floating plate 32 are maintained. The aperture of the drainage hole 49 is designed to be larger than that of the water filtering plate 18. This design ensures the engineering quality of the floating plate 32 and effectively prevents the internal pressure in the floating object lifting chamber 19 from becoming too high due to excessive water ingress. In addition, a grid 12 is opened at the upper end of the plug plate 48. This measure can assist the floating object lifting chamber 19 in draining excess water, further ensuring the stable operation of the system.

[0094] Adopting the above technical solution, the present invention has the following beneficial effects: (1) By ensuring that the total area of the drainage holes is smaller than the total water inlet area of the water filtering plate, the rising ability and energy of the floating plate are effectively maintained, thereby ensuring that the system can operate continuously and stably. (2) The aperture of the drainage hole is designed to be larger than that of the water filtering plate. This design not only ensures the engineering quality of the floating plate, but more importantly, effectively prevents the internal pressure in the floating object lifting chamber from becoming too high due to excessive water ingress, protecting the safety of the system. (3) Opening a grid at the upper end of the isolation plug plate can assist the floating object lifting chamber in draining excess water, further ensuring the stable operation of the system and extending the service life of the system. (4) This technical solution locally transforms the function of the original flood discharge ditch. By adding the isolation plug plate and drainage hole design between the sewage water conveyance pipeline and the floating object lifting chamber, the effective separation of sewage and floating objects is achieved, optimizing the performance of the engineering system.

[0095] As Figures 2 - 7 Figures 22 - 23 show a further implementation manner of this application. On both sides of the flood discharge ditch 1, there are gutter wall cement supports 51; the gutter wall cement supports 51 are filled with gravel 54; the gutter wall cement supports 51 include gutter surface wall panels 52 and support beams 53; there are two gutter surface wall panels 52 for limiting the gravel 54; the support beams 53 are arranged between the gutter surface wall panels 52; it also includes a grid - added switch - door rain grate 8; the grid - added switch - door rain grate 8 is arranged on the road surface above the gutter wall cement supports 51.

[0096] On both sides of the flood discharge ditch 1, there is usually a road 4. To ensure the cleanliness and safety of the public road environment, the engineering system has ingeniously designed the layout of the rainwater conveyance pipeline 9 and placed it under the public road environment. On both sides of the flood discharge ditch 1, the original ditch walls made of fragmented mountain stones were demolished and replaced by ditch wall cement brackets 51. These brackets 51 are directly installed in the position of the original ditch wall to ensure that the flood discharge capacity is consistent with the original design. The ditch wall cement bracket 51 is exquisitely constructed, with two ditch surface wall panels 52 as the vertical frames and three support beams 53 on each layer as the cross beams, forming an upper, middle, and lower three-layer structure. The ditch surface wall panels 52 and the support beams 53 are cast into one body with cement to ensure the stability and durability of the structure. On the top layer of the bracket, we laid a sidewalk 3 flush with the original ground and installed a rainwater grate 8 with a net and a switchable door to replace the existing permeable grate 7, so as to effectively collect and discharge the potential ground rainwater resources outside the flood discharge ditch 1 while ensuring the water quality of the conveyance pipeline. The rainwater conveyance pipeline 9 is placed on the middle layer support beam 53, and its bottom edge is aligned with the bottom horizontal position of the flood discharge ditch 1, which can quickly absorb, divert, and unload the rainwater 2 flowing down from the high plateau potential, and at the same time collect the potential rainwater resources outside the flood discharge ditch 1 along the way. On the third layer support beam 53, we placed the sewage conveyance pipeline 10. The initial pipe orifice of the sewage conveyance pipeline 10 is blocked by a plug plate 48 and buried in the roadside land 6 at the bottom of the flood discharge ditch 1 to achieve the connection with the original domestic sewage pipeline 5 on the side of the flood discharge ditch 1. This design effectively solves the contradictory relationship between the original domestic sewage and the environment. Each layer of the bracket is equipped with at least three support beams 53 to support the ditch wall cement bracket 51 composed of two ditch surface wall panels 52. After installation, we used the original ditch wall gravel 54 removed to fill the gap between the bracket and the pipeline, thus forming a stable overall structure that makes the flood unable to shake the combination of the ditch wall cement bracket 51, the rainwater conveyance pipeline 9, the sewage conveyance pipeline 10, and the gravel 54.

[0097] Adopting the above technical solution, the present invention has the following beneficial effects: (1) The cement support for the ditch wall adopts a cement casting structure of the ditch surface wall panel and the support beam, forming a stable and durable three-layer support system, effectively improving the overall stability of the flood drainage ditch and being able to resist flood impacts. (2) The design of the rainwater grate with a net belt and a switchable door can effectively collect and discharge the potential energy ground rainwater resources outside the flood drainage ditch, and at the same time ensure the water quality of the water conveyance pipeline. The setting of the rainwater conveyance pipeline can quickly absorb, divert and unload the rainwater flowing down from the plateau potential energy, improving the rainwater discharge efficiency. (3) The ingenious layout of the sewage conveyance pipeline blocks the initial pipe orifice with a plug plate and buries it in the ditch bottom soil, realizing the connection with the domestic sewage pipeline, effectively solving the contradiction between domestic sewage and the environment, and improving the surrounding environment. (4) The crushed stones after the original ditch wall is demolished are reused and filled in the gaps between the supports and the pipelines, not only forming a stable overall structure, but also saving the building material cost, reflecting the environmental protection concept of resource reuse.

[0098] Embodiment 2

[0099] In Figures 1 - 3 , on the ground outside the flood drainage ditch 1, the permeable grate 7 parallel to the ground is an important facility indispensable for the rainwater resource project that collects the rainwater resources with a potential difference. From Figure 24 the structure of the permeable grate 7 made of load-bearing cast iron shown, we can clearly see that its structural function is relatively simple and open. The cast iron grate bars 57 mainly bear the load-bearing function, while the cast iron drain holes 58 are in an unselective open state and have no screening effect on the inflowing water quality.

[0100] To ensure the water quality of the overall engineering system and the capacity of the plain storage project, we decided to directly replace the permeable grate 7 in the original position with the rainwater grate 8 with a net belt and a switchable door. This replacement is based on an in-depth analysis of the deficiencies of the existing system and the urgent consideration of the improvement requirements.

[0101] The system disclosed in this application is a key link connecting the plateau flowing water and the plain rainwater resource storage project, and its performance directly determines the effect of the plain rainwater resource storage project. In view of the decisive role of the system in this case on the subsequent engineering capacity, we considered and planned a possible cleaning and sorting facility at the initial design stage of the system.

[0102] As Figures 25 - 31The following shows a further embodiment of the present application, including a rain grate main body 59; an upper mesh grate 55 is provided at the upper end of the rain grate main body 59 for filtering large pieces of garbage; a cast iron permeable grate 7 is provided between the rain grate main body 59 and the upper mesh grate 55 for load-bearing; the permeable grate 7 includes a cast iron grate frame 56, cast iron grate bars 57 and cast iron drain holes 58; the cast iron grate frame 56 is rectangular, and a plurality of the cast iron grate bars 57 are arranged at intervals, and the gap between the cast iron grate frame 56 and the cast iron grate bars 57 is the cast iron drain hole 58; a rain grate drain hole 61 is also provided on the rain grate main body 59, and the position of the rain grate drain hole 61 corresponds to the cast iron drain hole 58 in the vertical direction; a door shaft rod hole 63 is provided on the side wall of the rain grate main body 59; it also includes a blocking door 64 and a door shaft rod 66; a door shaft ring 65 is provided on the blocking door 64; the door shaft ring 65 is coaxially arranged with the door shaft rod hole 63; the door shaft rod 66 passes through the door shaft rod hole 63 and the door shaft ring 65; it also includes corner platforms 68; there are two types of corner platforms 68, namely a first corner platform 68a and a second corner platform 68b; a fixing rod through hole 69 and a permeable hole 70 are provided on the first corner platform 68a; a permeable hole 70 is provided on the second corner platform 68b; an installation hole 62 is provided inside the rain grate main body 59, and the first corner platform 68a and the second corner platform 68b are fixed inside the rain grate main body 59 through the installation hole 62; the first corner platform 68a is installed on the installation hole 62 at the lower end of the door shaft rod 66; the second corner platform 68b is installed on the installation hole 62 on the other side; brushes 71 are provided on both the first corner platform 68a and the second corner platform 68b; it also includes a water tank 75, which is arranged below the rain grate main body 59; the water tank 75 is communicated with the rain grate main body 59 through the permeable hole 70; a bottom drain hole 76 is provided at the bottom of the water tank 75.

[0103] At the upper end of the rain grate main body 59, an upper grid grate 55 is provided. Its function is to filter large pieces of garbage to ensure that they cannot enter the drain holes 61 of the rain grate. Below the upper grid grate 55, the original cast iron permeable grate 7 undertakes the load-bearing task. Its load-bearing function ensures the flat use of the upper grid grate 55 and prevents it from being damaged. The flatness of the upper grid grate 55 is beneficial to mechanical cleaning, and thus effectively controls the quantity of the load-bearing substances on the surface of the obstruction door 64. The rain grate main body 59 is made of recycled waste plastics. The drain holes 61 of the rain grate correspond one by one with the cast iron drain holes 58. This not only realizes the reuse of waste, but also solves the problem of waste plastics degrading and occupying cultivated land. The door hinge rod 66 passes through the door hinge rod hole 63 on one side of the rain grate main body 59, passes through the door hinge ring 65 of the obstruction door 64, and then enters the door hinge rod hole 63 on the other side, thus movably suspending the obstruction door 64 above the water inlet at the upper end of the drain holes 61 of the rain grate with a net belt and a switch door 8. The corner platforms 68 are designed in two styles, and their tabletops are all covered with 1mm permeable holes 70. One kind of corner platform tabletop has fixed rod perforations 69 and permeable holes 70, while the other kind only has permeable holes 70. The corner platforms 68 are installed in the installation holes 62 of the frame of the rain grate main body 59, on both sides of the rain grate strip edge 60. In the installation hole 62 of the rain grate strip edge 60 below the door hinge rod 66, a corner platform 68 with fixed rod perforations 69 is installed; while in the installation hole 62 of the rain grate strip edge 60 without the door hinge rod 66 below, a corner platform 68 with only permeable holes 70 is installed. Brushes 71 are tied to both corner platforms 68. Through tests, the combined use of the corner platforms 68, the brushes 71 and the permeable holes 70 has achieved the best water collection effect. The round rod-shaped brushes 71 are placed closely against the vertical surface of the corner platforms 68, and together with the vertical surface of the corner platforms 68 and the upper surface of the brushes 71, they form a downward concave angle. When the flowing water passes through the vertical surface, it will closely adhere to the downward concave angle. Here, the water cannot flow out naturally (especially in the small water state), and can only seep or flow downward through the way of superposition and extrusion. The brushes 71 are located above the permeable holes 70, and the natural density of their bristles helps the permeable holes 70 to filter out particulate matters larger than the bristle density, making them roll down outside the brush body. The sediment in the flowing water is intercepted by the brushes and remains in the brush body, thus preventing the sediment from forming hard mud masses on the corner platforms 68. The brush body with this structure is very easy to loosen and fall off when encountering cement sediment and flow out of the brush body with the water. However, soil particles smaller than 1mm can easily pass through the permeable holes 70 with the water and enter the water tank 75. It should be noted that there are only two 2mm bottom drain holes 76 at the bottom of the water tank 75. Therefore, 1mm particulate matters cannot remain after entering the water tank, thus ensuring the purity of the water in the tank and further not affecting the normal operation of the rain grate floating block 74 in the tank.

[0104] With the above technical solution, the present invention has the following beneficial effects: (1) By replacing the original permeable grate with a rain grate with a screening belt for opening and closing the door, the system adds a function of screening the inflowing water quality. The upper grid grate can effectively filter large pieces of garbage to prevent it from entering the drainage system. The design of the cast iron drainage holes and the rain grate drainage holes, combined with the permeable holes and brushes on the corner platform, can further filter out sediment and fine particles, significantly improving the water quality of the rainwater resources stored in the plain. (2) The main body of the rain grate is made of recycled waste plastic, which not only realizes the reuse of waste but also improves the durability of the system. The permeable grate 7 made of cast iron ensures the load-bearing function, prevents the upper grid grate from being damaged, and maintains the stability of the system. (3) The corresponding design of the rain grate drainage holes and the cast iron drainage holes ensures that rainwater can flow smoothly into the system, improving the rainwater collection efficiency. At the same time, the design of the corner platform and the brush 71 optimizes the water flow path, preventing sediment from forming hard mud masses on the corner platform and further ensuring the collection of rainwater. (4) The flatness of the upper grid grate is conducive to mechanical cleaning, can effectively control the amount of load-bearing substances on the surface of the obstruction door, and reduces the workload and difficulty of manual maintenance. At the same time, the corresponding design of the rain grate drainage holes and the cast iron drainage holes makes the system easy to clean and maintain, reducing the management cost.

[0105] As Figures 25 - 41 shown in a further embodiment of the present application, it further includes a pull rope 72, a rain grate floating block 74, and a floating rod 73; the rain grate floating block 74 is arranged in the water tank 75, the floating rod 73 is arranged on the rain grate floating block 74, and its upper end passes through the fixed rod perforation 69; a pull door rope hole 67 is arranged on the obstruction door 64, one end of the pull rope 72 is tied in the pull door rope hole 67, and the other end is tied to the floating rod 73; a water tank buckle 77 is arranged at the top end of the water tank 75 for clamping on the bottom edge of the corner platform 68 to stably connect the water tank 75 to the main body 59 of the rain grate. The obstruction door 64 is installed at the water inlet at the upper end of the rain grate drainage hole 61 through the mobility of the door installation shaft rod 66. One end of the pull rope 72 is fixed in the pull door rope hole 67 of the obstruction door 64, and the other end is connected to the floating rod 73. After passing through the fixed rod perforation 69 of the corner platform 68, the floating rod 73 is installed or adhered to the rain grate floating block 74, and the floating block is located inside the water tank 75. The obstruction door 64 is fixed at the upper end of the water inlet with its downward-opening design, using the door installation shaft rod 66 as the lever balance fulcrum. The rain grate floating block 74 is used as a counterweight, and its weight is increased as much as possible to ensure that when the floating block floats, the pulling force of the door is reduced to zero, thereby realizing the automatic opening of the door.

[0106] The two corner platforms 68 fixed on both sides of the rain grate bar edge 60 tightly clamp it to form a stable whole. The width of the water tank 75 is based on the sum of the bottom edges of the two corner platforms 68 and the width of the rain grate bar edge 60. On both sides of the mouth of the water tank 75, there are water tank buckles 77 for fixing the bottom edge of the corner platform 68 to ensure that the water tank 75 is stably installed under the rain grate bar edge 60. In the case of water accumulation at the grate opening, blocked by the water flow obstruction door 64, water can only seep into the inside of the grate body through the low-side gap of the door and then flow to the brush 71 on the corner platform 68. After being filtered by the brush 71, the water continues to flow to the water permeable holes 70 on the corner platform 68. Since the diameter of the water permeable holes 70 is 1 mm, the water can easily pass through and directly enter the water tank 75. The water in the water tank 75 generates buoyancy, causing the rain grate floating block 74 to rise, and then driving the floating rod 73 to rise. The rise of the floating rod 73 causes the pull rope 72 to slacken. At this time, the pull door rope hole 67 is close to the fulcrum of the door installation shaft rod 66. Since the weight of the rain grate floating block 74 plays a major role in controlling the obstruction door 64, the slackening of the pull rope 72 causes the obstruction door 64 to lose balance at the fulcrum of the door installation shaft rod 66, and the side without the pull rope rotates and falls due to its own weight, thus realizing the opening of the door for draining water. When all the accumulated water in the water tank 75 is drained through the 2 mm bottom drainage holes 76 at the bottom, the rain grate floating block 74 and the connected floating rod 73 fall accordingly. The tightening of the floating rod 73 causes the pull rope 72 to exert a pulling force on the obstruction door 64, pulling it back to the original balanced position, thus closing the rain grate 8 with a net belt and a switchable door. The designs of the installation holes 62, the door installation shaft rod holes 63, the obstruction door 64, the door shaft ring 65, the door installation shaft rod 66, and the corner platform 68 all follow the principle of dispersion and recombination, making the entire rain grate 8 with a net belt and a switchable door easy to repair and replace components, and avoiding overall scrapping due to damage caused by minor collisions. The water collection capacity of the water tank 75 depends on the densely distributed 1 mm water permeable holes 70 on the corner platform 68, and the total area of which is larger than the total area of the two 2 mm bottom drainage holes 76 at the bottom of the water tank, ensuring that the water collection volume of the water tank 75 is always greater than the drainage volume, thus maintaining the floating ability of the rain grate floating block 74 and the water quality in the water tank 75.

[0107] By adopting the above technical solution, the present invention has the following beneficial effects: (1) The technical solution realizes the automatic opening and closing function of the rainwater grate with a mesh and a switch door by designing a linkage mechanism of the rainwater grate float, the float rod and the pull rope. When water accumulates in the water tank, the rainwater grate float rises to drive the float rod and the pull rope to automatically open the barrier door to drain water; after the water in the water tank is emptied, the rainwater grate float falls and the pull rope automatically pulls back the barrier door to close. This automated process greatly improves operating efficiency and reduces the need for manual intervention. (2) By using the upper mesh grate and the brush on the corner platform, large pieces of garbage and mud and other impurities are effectively filtered out, ensuring that the quality of rainwater flowing into the water tank is significantly improved. This double filtration design allows rainwater to be effectively purified during the collection process. (3) The stable connection design of the rainwater grate main body, the corner platform and the water tank, as well as the weight configuration of the rainwater grate float, ensure the stability and reliability of the entire system. Even under extreme weather conditions, the system can maintain normal operation and effectively prevent rainwater from flooding. (4) The technical solution follows the design principle of dispersion and reassembly, making each component easy to repair and replace. When a component is damaged, there is no need to replace the entire system, only the corresponding component needs to be replaced, which reduces the cost and difficulty of repair. (5) Through the design of automatic opening and closing, as well as the effective filtering function, the system not only improves the efficiency of rainwater collection, but also ensures the quality of the collected rainwater, providing a reliable guarantee for the subsequent use of rainwater. This helps to improve the efficiency of water resource utilization and promote sustainable development. (6) By comparing the total area of 1mm permeable holes on the corners of the water tank with the area of two 2mm drainage holes at the bottom of the water tank, the water tank naturally and perfectly preserves all its functions. (7) The overall system is integrated through the fixed connection of the floating block (buoyancy), the floating rod (clear movement direction), and the pull rope (pulling one to move the whole body), each of which plays its role, and the solution is carried out step by step without disrupting the order, thus solving the problem of environmental disasters in a simple and effective way.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
