Description

Technical Field

[0001] The present invention relates to the technical field of rainwater collection and treatment equipment, and in particular to a sponge city rainwater collection and reuse equipment. Background Art

[0002] A sponge city is a city that can absorb water like a sponge and retain rainwater to the greatest extent possible. Water-absorbing materials and rainwater collection and treatment equipment are set up in corresponding plots in the city to store water during heavy rains, and rainwater is collected and treated for recycling and reuse.

[0003] Although large impurities will be separated when rainwater is filtered and collected, it will carry some sediment in its flow. Such sediment will be filtered when it enters the rainwater collector. However, due to excessive rainfall in the rainy season, after the rainwater collector has been working for a long time, the filtered sediment will block the pipeline equipment if it is not cleaned in time, causing the equipment to not operate normally. Usually, people are required to go and clean it when it rains heavily, which not only affects the collection of rainwater, but also increases labor costs. In order to avoid the above problems, the following solution is proposed, which is specifically a sponge city rainwater collection and reuse equipment. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a sponge city rainwater collection and reuse device, including a tank body mechanism, the tank body mechanism also includes: a filter tank also includes: A tank body mechanism is provided with a storage space inside the tank body mechanism for storing collected rainwater; The filtering mechanism is provided with a filter for filtering impurities and sediment visible to the naked eye in rainwater; Sedimentation mechanism: the sedimentation mechanism is provided with a sedimentation plate to prevent the water flow from directly impacting the sedimentation pool; The inner wall of the filter tank is fixedly connected with a water baffle, the bottom of the inner wall of the filter tank is fixedly connected with a bottom inclined plate, the outer wall of the water baffle is fixedly connected with a grid plate, and the outer wall of the grid plate is fixedly connected to the inner wall of the filter tank.

[0005] Preferably, the tank structure includes: A tank assembly, which is fixedly connected to the outer wall of the tank mechanism and is used to store collected rainwater; The inlet assembly is fixedly connected to the top of the tank assembly and is used for connecting to an external pipe to guide the collected rainwater into the tank assembly.

[0006] Preferably, the filtering mechanism comprises: The filter assembly is fixedly connected to the inner wall of the tank assembly and is used to filter larger impurities such as leaves, weeds, etc. The replacement component is fixedly connected to the outer wall of the tank assembly and is used to open and close the filter tank to facilitate the replacement of its filter assembly.

[0007] Preferably, the precipitation mechanism comprises: The bottom assembly is fixedly connected to the inner wall of the tank assembly and is used to guide the accumulation of precipitated impurities; The sponge filter assembly is fixedly connected to the inner wall of the tank assembly to prevent impurities and sediments from floating up.

[0008] Preferably, the tank assembly includes a sewage outlet opened on the outer wall of the filter tank, the outer wall of the filter tank is provided with a drain outlet, the outer wall of the drain outlet is fixedly connected to a connecting pipe, and the end of the connecting pipe away from the drain outlet is fixedly connected to the stirring tank.

[0009] Preferably, the inlet assembly includes a water inlet opened on the top of the filter tank, and an observation mirror is fixedly connected to the top of the filter tank.

[0010] Preferably, the filter assembly includes a cartilage frame fitly connected to the surface of the grille plate, the inner wall of the cartilage frame is fixedly connected to the filter mesh cotton, and the outer wall of the cartilage frame is fixedly connected to the cartilage handle. When rainwater enters the interior of the device through the water inlet, it will fall on the filter mechanism, and the filter mechanism will filter out large particles or impurities such as leaves. When the transported rainwater impacts the grille plate, the grille plate will offset all the impact force, allowing the rainwater to pass through the filter mesh cotton and the grille plate into the lower end of the device. Because the filter mechanism filters impurities while resisting the impact of the water flow, the rainwater drips to the bottom through the filter mechanism, avoiding direct impact on the rainwater accumulated at the bottom, which causes the accumulated rainwater to become turbid during the sedimentation process and cannot be precipitated under the impact of the upper water flow.

[0011] Preferably, the replacement component includes a mounting port fixed on the surface of the filter tank, and an outer wall of the mounting port is provided with a closed door.

[0012] Preferably, the bottom assembly includes a bottom inclined plate fixedly connected to the bottom of the inner wall of the filter tank, the outer wall of the bottom inclined plate is fixedly connected to a too high inclined plate, and a sewage suction port is provided at the connection between the too high inclined plate and the bottom inclined plate. By utilizing the above-mentioned sedimentation characteristics, when rainwater is transported to the inside of the equipment through the water inlet, the rainwater will settle at the bottom of the filter tank during the process of accumulating at the bottom of the filter tank. Through the setting of the sewage suction port, the rainwater accumulated inside the filter tank is continuously increased in height, and the pressure applied to the bottom is also continuously increased. When the rainwater accumulates to a certain extent, the internal pressure drop is high, and the sewage suction port is connected to the sewage outlet. Due to the pressure, a large suction force will be generated, causing the rainwater accumulated inside the filter tank to flow to the sewage outlet through the sewage suction port. Since the sewage suction port is set small, the flow rate nearby is accelerated and the suction force is stronger. However, since the sewage suction port is set small, the suction force generated is limited and cannot change the operation mode inside the filter tank. The suction force generated by the sewage suction port will cause the sediment originally settled at the bottom of the filter tank to be sucked away through the sewage suction port, avoiding excessive sediment deposition inside the filter tank, exceeding the gap reserved at the bottom of the baffle, resulting in the accumulated rainwater unable to flow normally through the gap reserved at the bottom of the baffle.

[0013] Preferably, the sponge filter assembly includes a mounting frame fixedly connected to the inner wall of the filter tank, the outer wall of the mounting frame is fixedly connected to the outer wall of the baffle, and the top of the mounting frame is fixedly connected with filter cotton. To address the problem of sediment blockage, when rainwater enters the filter tank, it will accumulate inside the filter tank. During the accumulation process, the sediment will settle to the bottom due to its own weight. At the same time, as rainwater continues to accumulate inside the filter tank, the water level inside the filter tank continues to rise. When the accumulated water level rises above the filter cotton, due to the setting of the baffle, the rainwater accumulated at one end of the filter cotton is relatively calm, and there is no other power or other reasons inside to cause shaking. The sediment that has not naturally settled will be intercepted at the bottom of the filter cotton. When the rainwater level reaches the drain outlet and flows to the mixing tank, the water level reaches the drain outlet The flow force generated during the rain is a natural flow. The bottom of the rainwater will not be affected by this force, and the sediment will not be affected by the suction and will flow upward with the water flow through the filter cotton, causing the inside or outer surface of the filter cotton to be filled with sediment, resulting in blockage and difficulty in cleaning, affecting the efficiency of the equipment's rainwater recovery; utilizing the above-mentioned rainwater accumulation and sedimentation process, the equipment filter tank is provided with a bottom inclined plate at the bottom, and the top of the bottom inclined plate is fixedly connected with a too-high inclined plate, which is provided on the side far from the filter cotton, called the right side of the equipment, and the filter cotton end is the left side. The sediment will settle on the outer surface of the bottom inclined plate and the too-high inclined plate to avoid long-term sedimentation that causes some sediment to be unable to be discharged from the sewage suction port and gather. The equipment through the bottom inclined plate and the too-high inclined plate can effectively prevent the sediment from accumulating into blocks.

[0014] The present invention has the following beneficial effects: (1) The present invention addresses the problem of silt blockage. When rainwater enters the filter tank, it accumulates inside the filter tank. During the accumulation process, the silt will settle to the bottom due to its own weight. At the same time, as the rainwater continues to accumulate inside the filter tank, the water level inside the filter tank continues to rise. When the accumulated water level rises above the filter cotton, due to the setting of the baffle, the rainwater accumulated at one end of the filter cotton is relatively calm, and there is no other power or other reasons for shaking inside. The silt that has not naturally settled will be intercepted at the bottom of the filter cotton. When the rainwater reaches the drain outlet and flows to the mixing tank, the flow force generated when the horizontal plane reaches the drain outlet is natural flow. The bottom of the rainwater will not be affected by this force, and the silt will not be affected by the suction force and will flow upward with the water flow through the filter cotton, causing the inside or outer surface of the filter cotton to be filled with silt, resulting in the problem of blockage that is difficult to clean, affecting the efficiency of the equipment's rainwater recovery.

[0015] (2) The present invention utilizes the above-mentioned sedimentation characteristics. After rainwater is transported to the interior of the equipment through the water inlet, it will settle at the bottom of the filter tank during the process of accumulating at the bottom of the filter tank. Through the setting of the sewage suction port, the rainwater accumulated inside the filter tank increases in height while the pressure exerted on the bottom also increases. When the rainwater accumulates to a certain extent, the internal pressure drop is high, and the sewage suction port is connected to the sewage outlet. Due to the pressure relationship, a large suction force is generated, causing the rainwater accumulated inside the filter tank to flow to the sewage outlet through the sewage suction port. Since the sewage suction port is set small, the flow rate to the vicinity is accelerated and the suction force is strong. However, since the sewage suction port is set small, the suction force generated is limited and cannot change the operation mode inside the filter tank. The suction force generated by the sewage suction port will cause the sediment originally settled at the bottom of the filter tank to be sucked away through the sewage suction port, avoiding excessive sedimentation inside the filter tank, which exceeds the gap reserved at the bottom of the baffle, resulting in the accumulated rainwater being unable to flow normally through the gap reserved at the bottom of the baffle.

[0016] (3) The present invention utilizes the above-mentioned process of rainwater accumulation and sedimentation. A bottom inclined plate is provided at the bottom of the equipment filter tank. A high inclined plate is fixedly connected to the top of the bottom inclined plate. The high inclined plate is provided on the side away from the filter cotton, which is called the right side of the equipment. One end of the filter cotton is the left side. The sediment will settle on the outer surface of the bottom inclined plate and the high inclined plate, avoiding long-term sedimentation that causes some sediment to be unable to be discharged from the sewage suction port and to gather. The equipment through the bottom inclined plate and the high inclined plate can effectively prevent the sediment from accumulating into blocks.

[0017] (4) In the present invention, when rainwater enters the interior of the device through the water inlet, it will fall on the filter mechanism, which will filter out large particles or impurities such as leaves. When the transported rainwater impacts the grille plate, the grille plate will offset all the impact force, allowing the rainwater to pass through the filter mesh cotton and the grille plate and enter the lower end of the device. Since the filter mechanism filters impurities while resisting the impact of the water flow, the rainwater will drip to the bottom through the filter mechanism, avoiding direct impact on the rainwater accumulated at the bottom. The rain causes the accumulated rainwater to become turbid during the sedimentation process and cannot be precipitated under the impact of the water flow from the upper end.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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 making creative efforts are within the scope of protection of the present invention.

[0022] For example 1, please refer to Figure 1-Figure 5 The present invention is a sponge city rainwater collection and reuse device, including a tank body mechanism 1, the tank body mechanism 1 also includes: a filter tank 111 also includes: The tank body 1 has a storage space inside for storing collected rainwater; Filter mechanism 2, which is provided with a filter for filtering impurities and sediment visible to the naked eye in rainwater; Sedimentation mechanism 3, which is provided with a sedimentation plate to prevent water flow from directly impacting the sedimentation pool; The inner wall of the filter tank 111 is fixedly connected with a water baffle 123 , the bottom of the inner wall of the filter tank 111 is fixedly connected with a bottom inclined plate 311 , the outer wall of the water baffle 123 is fixedly connected with a grid plate 211 , and the outer wall of the grid plate 211 is fixedly connected to the inner wall of the filter tank 111 .

[0023] The tank body mechanism 1 comprises: The tank assembly 11 is fixedly connected to the outer wall of the tank mechanism 1 and is used to store collected rainwater; The inlet assembly 12 is fixedly connected to the top of the tank assembly 11 and is used for connecting to an external pipeline to guide the collected rainwater into the tank assembly 11.

[0024] The filtering mechanism 2 includes: The filter assembly 21 is fixedly connected to the inner wall of the tank assembly 11 and is used to filter larger impurities such as leaves, weeds, etc.; The replacement component 22 is fixedly connected to the outer wall of the tank assembly 11 and is used to open and close the filter tank 111 to facilitate the replacement of its filter assembly.

[0025] The precipitation mechanism 3 includes: The bottom assembly 31 is fixedly connected to the inner wall of the tank assembly 11 and is used to guide the accumulation of precipitated impurities; The sponge filter assembly 32 is fixedly connected to the inner wall of the tank assembly 11 to prevent impurities and sediments from floating up.

[0026] The tank assembly 11 includes a sewage outlet 112 opened on the outer wall of the filter tank 111. The outer wall of the filter tank 111 is provided with a drain outlet 113. The outer wall of the drain outlet 113 is fixedly connected to a connecting pipe 115. The end of the connecting pipe 115 away from the drain outlet 113 is fixedly connected to the stirring tank 114.

[0027] The inlet assembly 12 includes a water inlet 121 opened at the top of the filter tank 111 , and an observation mirror 122 is fixedly connected to the top of the filter tank 111 .

[0028] The filter assembly 21 includes a cartilage frame 212 that is fitted and connected to the surface of the grille plate 211. The inner wall of the cartilage frame 212 is fixedly connected to a filter mesh cotton 214, and the outer wall of the cartilage frame 212 is fixedly connected to a cartilage handle 213. When rainwater enters the interior of the device through the water inlet 121, it will fall on the filter mechanism 2. The filter mechanism 2 will filter out large particles or impurities such as leaves. When the transported rainwater impacts the grille plate 211, the grille plate 211 will offset all the impact force, allowing the rainwater to pass through the filter mesh cotton 214 and the grille plate 211 into the lower end of the device. Because the filter mechanism 2 filters impurities while resisting the impact of the water flow, the rainwater drips to the bottom through the filter mechanism 2, avoiding direct impact on the rainwater accumulated at the bottom, which causes the accumulated rainwater to become turbid during the sedimentation process and cannot be precipitated under the impact of the upper water flow.

[0029] For example 2, please refer to Figure 3-Figure 9 The present invention is a sponge city rainwater collection and reuse device. Based on Example 1, the replacement component 22 includes a mounting port 221 fixed on the surface of the filter tank 111, and the outer wall of the mounting port 221 is provided with a closed door 222.

[0030] The bottom assembly 31 includes a bottom inclined plate 311 fixedly connected to the bottom of the inner wall of the filter tank 111, and the outer wall of the bottom inclined plate 311 is fixedly connected to a too high inclined plate 312, and a sewage suction port 313 is provided at the connection between the too high inclined plate 312 and the bottom inclined plate 311. By utilizing the above-mentioned sediment sedimentation characteristics, when rainwater is transported to the inside of the equipment through the water inlet 121, it will be deposited at the bottom of the filter tank 111 during the process of accumulating at the bottom of the filter tank 111. Through the setting of the sewage suction port 313, the rainwater accumulated in the filter tank 111 is continuously increased in height, and the pressure applied to the bottom is also continuously increased. When the rainwater accumulates to a certain extent, the internal pressure drop is high, and the sewage suction port 313 is connected to the sewage outlet 1 When 12 is turned on, a greater suction force is generated due to the pressure, causing the rainwater accumulated inside the filter tank 111 to flow to the sewage outlet 112 through the sewage suction port 313. Since the sewage suction port 313 is set small, the flow rate in the vicinity is accelerated and the suction force is stronger. However, since the sewage suction port 313 is set small, the suction force generated is limited and cannot change the operation mode inside the filter tank 111. The suction force generated by the sewage suction port 313 will cause the mud and sand originally settled at the bottom of the filter tank 111 to be sucked away through the sewage suction port 313, avoiding excessive sedimentation inside the filter tank 111, which exceeds the gap reserved at the bottom of the baffle 123, resulting in the accumulated rainwater being unable to flow normally through the gap reserved at the bottom of the baffle 123.

[0031] The sponge filter assembly 32 includes a mounting frame 321 fixedly connected to the inner wall of the filter tank 111, the outer wall of the mounting frame 321 is fixedly connected to the outer wall of the water barrier 123, and the top of the mounting frame 321 is fixedly connected with the filter cotton 322. To solve the problem of sediment blockage, when rainwater enters the filter tank 111, it will accumulate inside the filter tank 111. During the accumulation process, the sediment will settle to the bottom due to its own weight. At the same time, as the rainwater continues to accumulate inside the filter tank 111, the water level inside the filter tank 111 continues to rise. When the accumulated water level rises above the filter cotton 322, due to the setting of the water barrier 123, the rainwater accumulated at one end of the filter cotton 322 is relatively calm, and there is no other power or other reasons inside to cause shaking. The sediment that has not naturally settled will be intercepted at the bottom of the filter cotton 322. When the rainwater level reaches the drain outlet 113 and flows to the mixing tank 114, the water level reaches the drain The flow force generated by opening 113 is a natural flow, and the bottom of the rainwater will not be affected by this force, and the sediment will not be affected by the suction force and will flow upward with the water flow through the filter cotton 322, causing the inside or outer surface of the filter cotton 322 to be filled with sediment, resulting in blockage and difficulty in cleaning, affecting the efficiency of the equipment's rainwater recovery; utilizing the above-mentioned rainwater accumulation and sedimentation process, the bottom of the equipment filter tank 111 is provided with a bottom inclined plate 311, and the top of the bottom inclined plate 311 is fixedly connected with a high inclined plate 312, which is arranged on the side far from the filter cotton 322, called the right side of the equipment, and one end of the filter cotton 322 is the left side. The sediment will settle on the outer surface of the bottom inclined plate 311 and the high inclined plate 312, avoiding long-term sedimentation that causes some sediment to be unable to be discharged by the sewage suction port 313 and gather. The equipment through the bottom inclined plate 311 and the high inclined plate 312 can effectively prevent sediment from accumulating into blocks.

[0032] A specific application of this embodiment is: before use, the water inlet 121 is connected to the rainwater collector through a pipe, or the preliminarily filtered rainwater is transported to the water inlet 121 through other pipes. Some large particles of impurities that have not been cleaned will be intercepted by the filter mechanism 2 and fall into the installation port 221. The filter mesh cotton 214 is cleaned or replaced by opening the closed door 222. The filter mesh cotton 214 is fixed on the cartilage frame 212. It can be pulled out and replaced after being deformed by the own characteristics of the cartilage frame 212. The sewage outlet 112 is connected to the sewage pipe. According to the usage scenario, the drain outlet 113 can be connected to the mixing tank 114 or other subsequent processes. The internal situation can be observed through the observation mirror 122. When rainwater enters the filter tank 111, it will accumulate inside the filter tank 111. During the accumulation process, the mud and sand will be removed by itself. The weight of the body settles at the bottom. At the same time, as rainwater continues to accumulate inside the filter tank 111, the water level inside the filter tank 111 continues to rise. When the accumulated water level rises and exceeds the filter cotton 322, due to the setting of the baffle 123, the rainwater accumulated at one end of the filter cotton 322 is relatively calm, and there is no other power or other reasons inside to cause shaking. The sediment that has not naturally settled will be intercepted at the bottom of the filter cotton 322. When the rainwater level reaches the drain outlet 113 and flows to the mixing tank 114, the flow force generated when the horizontal plane reaches the drain outlet 113 is natural flow. The bottom of the rainwater will not be affected by this force, and the sediment will not be affected by the suction force and will flow upward with the water flow through the filter cotton 322, causing the inside or outer surface of the filter cotton 322 to be filled with sediment, resulting in blockage that is difficult to clean, affecting the efficiency of the equipment's rainwater recovery.

[0033] By utilizing the above-mentioned sediment sedimentation characteristics, after rainwater is transported into the interior of the device through the water inlet 121, it will settle at the bottom of the filter tank 111 during the process of accumulating at the bottom of the filter tank 111. Through the setting of the sewage suction port 313, the rainwater accumulated inside the filter tank 111 is continuously increased in height, and the pressure exerted on the bottom is also continuously increased. When the rainwater accumulates to a certain extent, the internal pressure drop is high, and the sewage suction port 313 is connected to the sewage outlet 112, which generates a large suction force due to the pressure relationship, so that the rainwater accumulated inside the filter tank 111 is discharged through the sewage suction port. 313 flows toward the sewage outlet 112. Since the sewage suction port 313 is set to be small, the flow velocity in the vicinity is accelerated and the suction force is stronger. However, since the sewage suction port 313 is set to be small, the suction force generated is limited and cannot change the operation mode inside the filter tank 111. The suction force generated by the sewage suction port 313 will cause the mud and sand originally settled at the bottom of the filter tank 111 to be sucked away through the sewage suction port 313, avoiding excessive sedimentation inside the filter tank 111, exceeding the gap reserved at the bottom of the baffle 123, resulting in the accumulated rainwater being unable to flow normally through the gap reserved at the bottom of the baffle 123.

[0034] Utilizing the above-mentioned process of rainwater accumulation and sedimentation, a bottom inclined plate 311 is provided at the bottom of the equipment filter tank 111, and a too-high inclined plate 312 is fixedly connected to the top of the bottom inclined plate 311. The too-high inclined plate 312 is provided on the side away from the filter cotton 322, which is called the right side of the equipment, and one end of the filter cotton 322 is the left side. The mud and sand will settle on the outer surface of the bottom inclined plate 311 and the too-high inclined plate 312 to avoid long-term sedimentation causing some mud and sand to be unable to be discharged from the sewage suction port 313 and to gather. The equipment through the bottom inclined plate 311 and the too-high inclined plate 312 can effectively prevent mud and sand from accumulating into blocks.

[0035] When rainwater enters the equipment through the water inlet 121, it will fall on the filter mechanism 2, and the filter mechanism 2 will filter out large particles or impurities such as leaves. When the transported rainwater impacts the grille plate 211, the grille plate 211 will offset all the impact force, allowing the rainwater to pass through the filter mesh cotton 214 and the grille plate 211 and enter the lower end of the equipment. Since the filter mechanism 2 filters impurities while resisting the impact of the water flow, the rainwater flows through the filter mechanism 2 and slides to the bottom, avoiding direct impact on the rainwater accumulated at the bottom, resulting in turbidity in the accumulated rainwater during the sedimentation process, and the problem of being unable to settle under the impact of the water flow from the upper end.
