Description

Technical Field

[0001] The invention relates to the technical field of rainwater resource recycling and reuse, and in particular to a greening rainwater collection device. Background Art

[0002] The water industry is an energy-intensive industry. In the context of urbanization, urban development has increased urban water consumption, drainage, and impermeable underlying surfaces in cities. Therefore, water quality deterioration, water shortages, and floods have become issues that urban development must face. In order to save water resources, realize resource utilization of drainage in buildings, and reduce carbon emissions, renewable water resource utilization technology is a practical measure.

[0003] Reusing rainwater can reduce the amount of rainwater discharged and the impact on the urban water environment, reduce the load on the urban drainage system, and effectively use rainwater to save fresh water resources. In the prior art, rainwater in the factory is directly discharged to the rainwater system in the factory through the downpipes of the building, and is directly discharged into the water body after meeting the discharge standards. A large amount of rainwater discharged will quickly increase the load of the urban drainage system on rainy days and aggravate the impact on the urban water environment. Summary of the invention

[0004] In view of this, the present invention provides a greening rainwater collection device to solve the problem in the prior art that urban factory rainwater treatment will increase the load of the urban drainage system.

[0005] In a first aspect, the present invention provides a greening rainwater collection device, comprising:

[0006] A water storage member, which is provided with an overflow channel, wherein the overflow channel is arranged through the water storage member, and the inlet of the overflow channel is at a preset height from the bottom of the water storage member;

[0007] A green plant tray is installed on the top of the water storage component, and the bottom surface of the green plant tray is communicated with the inner cavity of the water storage component.

[0008] The greening rainwater collection device is installed in the urban factory. The rainwater in the factory area is collected through the water storage part. The green plant tray is installed on the top of the water storage part, and its bottom surface is connected to the inner cavity of the water storage part, so that the plants in the green plant tray can directly absorb water from the water storage part, realizing the collection and utilization of rainwater. When the amount of rainwater is large in a short period of time, as the amount of rainwater collected in the water storage part increases and the water level in the water storage part rises to above the preset height, as an emergency treatment measure, the excess rainwater is discharged through the overflow channel. By collecting rainwater and using it for green plant irrigation, the dependence of urban greening on traditional freshwater resources can be reduced, and the utilization efficiency of water resources can be improved. At the same time, storing and utilizing rainwater in the water storage part can reduce the amount of rainwater directly discharged into the urban drainage system and reduce the load on the drainage system.

[0009] In an alternative embodiment, the green plant tray includes a green plant layer and a planting soil layer, and the green plant bodies in the green plant layer are planted in the planting soil layer. This enables the green plants to grow stably in the green plant tray. The planting soil layer provides necessary nutrients and support for the green plants, while ensuring that the roots of the green plants can effectively absorb water from the water storage component, promoting the healthy growth of the green plants and improving the greening effect.

[0010] In an alternative embodiment, the planting soil layer includes a first filter layer, a second filter layer, and a third filter layer that are sequentially laid from top to bottom. The pore size of the first filter layer, the pore size of the second filter layer, and the pore size of the third filter layer decrease in sequence or the pore size of the first filter layer, the pore size of the second filter layer, and the pore size of the third filter layer increase in sequence. By setting the planting soil layer as a layered structure, impurities in rainwater can be effectively filtered, reducing the impurities entering the water storage component, reducing the accumulation of impurities in the water storage component, and reducing the frequency of maintenance and dredging of the water storage component.

[0011] In an alternative embodiment, the overflow channel includes an inflow filter pipe and an overflow pipe that are sequentially connected. The inflow filter pipe is installed in the inner cavity of the water storage component, and the overflow pipe penetrates the water storage component and extends outside the overflow pipe. When the water level in the water storage component reaches a preset height, the excess rainwater enters the overflow pipe through the inflow filter pipe and is discharged. The inflow filter pipe can further filter the impurities in the rainwater, prevent the overflow channel from being blocked, and ensure the normal operation of the device.

[0012] In an alternative embodiment, one end of the inflow filter pipe is connected to the overflow pipe, and the other end is fixedly connected to the inner wall of the water storage component. An inflow port is penetrated through the side wall of the inflow filter pipe. By fixedly installing the inflow filter pipe in the inner cavity of the water storage component, the stability and reliability of the inflow filter pipe are ensured, avoiding loosening or displacement of the inflow filter pipe caused by water flow impact, and improving the stability and service life of the device.

[0013] In an alternative embodiment, the water storage component includes a water storage part and an auxiliary part that are interconnected. The auxiliary part is arranged at the bottom of the water storage part, and the auxiliary part extends away from the water storage part in a conical shape. The end with a larger inner cavity size of the auxiliary part is connected to the water storage part in a matching manner. This enables the impurities deposited at the bottom of the water storage component to be collected in the bottom space of the auxiliary part under the action of gravity, facilitating the subsequent maintenance and dredging work.

[0014] In an alternative embodiment, an auxiliary opening is provided on the auxiliary part, and an auxiliary cover is detachably installed on the auxiliary opening to facilitate the cleaning and maintenance of the auxiliary part. The detachable auxiliary cover can be conveniently opened to clean the impurities and sediments in the auxiliary part, ensuring the cleanliness and smoothness of the water storage component, and improving the maintenance convenience and service life of the device.

[0015] In an alternative embodiment, one end of the auxiliary part facing away from the water storage part extends downward into the underground soil layer. By extending the auxiliary part into the underground soil layer, the rainwater in the water storage member can directly penetrate into the underground soil layer, thereby reducing the amount of rainwater that needs to be treated and reducing the rainwater discharge pressure in rainy weather.

[0016] In an alternative embodiment, a water intake assembly is installed on the water storage member. The water intake assembly is arranged near the bottom of the water storage member, facilitating the extraction of rainwater from the water storage member for other uses, such as irrigation, cleaning, etc., and improving the comprehensive utilization efficiency of rainwater.

[0017] In an alternative embodiment, a liquid level indicator is installed in the water storage member. The liquid level indicator can monitor the water level in the water storage member in real time, facilitating the user to timely understand the water storage state of the water storage member and make subsequent work arrangements, avoiding the situation that the greening rainwater collection device cannot collect rainwater normally in the rainy day emergency state due to the too high water level in the water storage member, and improving the use safety and reliability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] The embodiments of the present invention will be described below in conjunction with Figure 1 to describe the embodiments of the present invention.

[0023] According to an embodiment of the present invention, on the one hand, a greening rainwater collection device is provided, which includes a water storage member 1 and a green plant tray 2.

[0024] An overflow channel 3 is installed on the water storage member 1. The overflow channel 3 penetrates through the water storage member 1, and the entrance of the overflow channel 3 is at a preset height from the bottom of the water storage member 1. The green plant tray 2 is installed on the top of the water storage member 1, and the bottom surface of the green plant tray 2 is communicated with the inner cavity of the water storage member 1, so that the plant roots planted in the green plant tray 2 can directly absorb the required water from the inner cavity of the water storage member 1.

[0025] In practical applications, the device is installed in an urban factory, and the water storage member 1 is arranged in the factory area to collect rainwater from the roof and the ground. The green plant tray 2, as the top component, the communication between its bottom surface and the inner cavity of the water storage member 1 ensures that plants can directly utilize the rainwater stored in the water storage member 1, realizing the reuse of rainwater resources. When encountering a short-term heavy rainfall condition, as the rainwater in the water storage member 1 continues to be collected, the water level gradually rises. When the water level reaches the preset height, the excess rainwater will be safely discharged through the overflow channel 3 to prevent the water storage member 1 from overflowing or being damaged due to too high a water level. The greening rainwater collection device can effectively collect rainwater in rainy weather and convert it into green plant irrigation water in non-rainy weather, thereby significantly reducing the dependence of urban greening on traditional municipal water supply and improving the comprehensive utilization rate of water resources. At the same time, the storage and reuse of rainwater in the water storage member 1 can reduce the amount of rainwater directly discharged into the urban drainage network in rainy weather, effectively reducing the operating load of the urban drainage system, and having multiple benefits of water conservation, emission reduction and environmental protection. This device is particularly suitable for industrial factory areas, urban buildings and public greening areas, and can be an important part of green infrastructure to help achieve sustainable management of urban water resources.

[0026] In one embodiment, the green plant tray 2 is composed of a green plant layer 204 and a planting soil layer. The green plant body in the green plant layer 204 is firmly planted in the planting soil layer, ensuring that the green plants can grow stably in the green plant tray 2. The planting soil layer not only provides necessary nutrients and support for the green plants, but also can fully absorb the water vapor evaporated and rising from the water storage member 1, ensuring that the green plant roots can efficiently absorb water from the water storage member 1, thereby promoting the healthy growth of the green plants and improving the greening effect. In practical applications, the green plant layer 204 and the planting soil layer can be fixed in various ways, such as using a fixing frame or a bonding material to ensure a tight connection between the green plant layer 204 and the planting soil layer. In addition, the material of the planting soil layer can be adjusted according to different green plant requirements, such as adding an appropriate amount of organic fertilizer or minerals to further improve the growth quality of the green plants.

[0027] In this embodiment, the planting soil layer includes a first filter layer 201, a second filter layer 202, and a third filter layer 203 that are sequentially laid from top to bottom. The pore sizes of the first filter layer, the second filter layer, and the third filter layer increase in sequence, that is, the pore size of the first filter layer 201 is smaller than the pore size of the second filter layer 202, and the pore size of the second filter layer 202 is smaller than the pore size of the third filter layer 203. The first filter layer 201 is set as a sandy soil layer, the second filter layer 202 is set as a gravel and sand layer, and the third filter layer is set as a pebble layer. By setting the planting soil layer as a layered structure, impurities in rainwater can be effectively filtered, the impurity content entering the water storage member 1 can be reduced, thereby reducing the accumulation of impurities in the water storage member 1 and reducing the frequency of maintenance and dredging. Specifically, the first filter layer 201 is mainly responsible for preliminary filtration. The pore size of the first filter layer 201 in the planting soil layer is the smallest, which is used to initially block particulate impurities in rainwater; the second filter layer 202 further filters. The pore size of the second filter layer 202 is moderate, which is used to assist in removing particulate impurities in rainwater; the third filter layer 203 plays a role of support and drainage, ensuring that the water in the lower water storage member 1 can enter the first filter layer 201 after evaporation and be absorbed by the root system of the green plant body.

[0028] In some other embodiments, the pore sizes of the first filter layer, the second filter layer, and the third filter layer decrease in sequence, and the pore sizes of the fillers inside the first filter layer gradually increase from top to bottom, the pore sizes of the fillers inside the second filter layer gradually increase from top to bottom, and the pore sizes of the fillers inside the third filter layer gradually increase from top to bottom. That is, the pore size distribution of the entire planting soil layer is from large to small, and the pore size distribution of the fillers in each of the first filter layer 201, the second filter layer 202, and the third filter layer 203 is from small to large. Moreover, the densities of the first filter layer 201, the second filter layer 202, and the third filter layer 203 gradually increase, and the particle sizes of the fillers in the first filter layer 201, the second filter layer 202, and the third filter layer 203 gradually decrease. Specifically, anthracite is selected for the first filter layer 201, quartz sand is selected for the second filter layer 202, and magnetite ore is selected for the third filter layer 203. By placing a light filter material anthracite with a smaller density and a larger particle size in the upper part and heavy filter materials quartz sand and magnetite ore with a larger density and a smaller particle size in the lower part. After backwashing with water, it will naturally stratify, with the light filter material on the upper layer and the heavy filter material on the lower layer, so that the particle sizes of the entire filter layer are divided into three layers from large to small. The pore size of the upper layer filter material is larger than that of the lower layer filter material, but the particle size of each filter layer inside is from small to large from top to bottom, enabling fine suspended particles to migrate smoothly into the third filter layer in the lower layer, so that the entire filter layer can play a better filtering role and improve the water quality entering the water storage member.

[0029] In practical applications, the thickness and material composition of each layer can be adjusted according to different rainwater qualities and usage environments. For example, in areas with more rainwater impurities, the thickness of the first filter layer 201 and the second filter layer 202 can be increased. As an alternative implementation, the planting soil layer can also include an activated carbon layer or other filter material layers to further improve the filtration effect and water quality purification ability.

[0030] In one embodiment, the overflow channel 3 includes an inlet filtration pipe 301 and an overflow pipe 302 that are connected in sequence. The inlet filtration pipe 301 is installed in the inner cavity of the water storage member 1, and the overflow pipe 302 penetrates through the water storage member 1 and extends outside the overflow pipe 302. When the water level in the water storage member 1 reaches a preset height, the excess rainwater enters the overflow pipe 302 through the inlet filtration pipe 301 and is discharged. The inlet filtration pipe 301 can further filter the impurities in the rainwater, prevent the overflow channel 3 from being blocked, and ensure the normal operation of the device. As an alternative implementation, the overflow channel 3 can also include multiple parallel filtration pipes to improve the filtration efficiency and processing capacity.

[0031] In this embodiment, one end of the inlet filtration pipe 301 is connected to the overflow pipe 302, and the other end is fixedly sealed to the inner wall of the water storage member 1 by welding. A plurality of inlet ports are provided through the side wall of the inlet filtration pipe 301. By fixedly installing the inlet filtration pipe 301 in the inner cavity of the water storage member 1, the stability and reliability of the inlet filtration pipe 301 are ensured, and the loosening or displacement of the inlet filtration pipe 301 caused by water flow impact is avoided, improving the stability and service life of the device.

[0032] In some other embodiments, one end of the inlet filtration pipe 301 can be connected to the overflow pipe 302 and then installed in the water storage member 1 through a mounting frame. A filter screen can be installed as a filter element during filtration, and the filtration aperture of the filter screen can be adjusted according to actual needs. For example, in areas with more rainwater impurities, a filter screen with a smaller aperture can be used to improve the filtration effect.

[0033] In one embodiment, the water storage member 1 includes a cylindrical tank serving as a water storage part 101 and a conical tank serving as an auxiliary part 102 that are connected to each other. The auxiliary part 102 is provided at the bottom of the water storage part 101, and the auxiliary part 102 extends away from the water storage part 101 in a conical shape. The end with a larger inner cavity size of the auxiliary part 102 is connected to the water storage part 101. This enables the impurities at the bottom of the water storage member 1 to naturally settle under the action of gravity and be collected in the bottom space of the auxiliary part 102, facilitating subsequent maintenance and dredging work.

[0034] In one embodiment, the auxiliary part 102 is provided with an auxiliary opening 4, and an auxiliary cover is detachably mounted on the auxiliary opening 4 to facilitate cleaning and maintenance of the auxiliary part 102. The auxiliary opening 4 can be conveniently opened through the detachable auxiliary cover to clean impurities and sediments in the auxiliary part 102, thereby ensuring the cleanliness and unobstructed flow of the water storage part 1, and improving the maintenance convenience and service life of the device. As an alternative embodiment, the auxiliary opening 4 can be designed as a plurality of small openings arranged at different positions, each of which is equipped with an independent cover to facilitate cleaning in different areas.

[0035] In one embodiment, one end of the auxiliary part 102 away from the water storage part 101 extends downward into the underground soil layer 6. By extending the auxiliary part 102 into the underground soil layer 6, rainwater in the water storage part 1 can directly penetrate into the underground soil layer 6, thereby reducing the amount of rainwater that needs to be treated and reducing the rainwater discharge pressure in rainy weather. As an alternative embodiment, the auxiliary part 102 can be designed as an infiltration pipe to further improve the infiltration efficiency of rainwater into the underground soil layer 6.

[0036] In one embodiment, a water intake assembly 5 is installed on the water storage member 1, and the water intake assembly 5 includes a water intake pipe extending into the inner cavity of the water storage member and a water intake nozzle installed on the water intake pipe for controlling the water flow, and the water intake nozzle is used to communicate with an external pipeline. The water intake assembly 5 is arranged near the bottom of the water storage member 1, so that it is convenient to communicate with the water intake nozzle through an external pipeline to take out rainwater from the water storage member 1 for other purposes, such as irrigation, cleaning, etc., so as to improve the comprehensive utilization efficiency of rainwater.

[0037] In this embodiment, one group of water intake components 5 is provided, and the water intake components 5 include a water intake pipe connected to the inner cavity of the water storage member 1 and a switch valve installed on the water intake to control the on and off of the water intake pipe. As an alternative embodiment, the water intake components 5 may also include multiple groups arranged in the height direction, and each group of water intake components 5 is located at a different height of the water storage member 1, so as to take rainwater of different water qualities as needed.

[0038] In one embodiment, a liquid level gauge as a liquid level indicator is installed in the water storage member 1. The liquid level indicator can monitor the water level in the water storage member 1 in real time, so that the user can timely understand the water storage status of the water storage member 1 and make subsequent work arrangements, thereby avoiding the greening rainwater collection device being unable to collect rainwater normally in an emergency state on rainy days due to the excessively high water level in the water storage member 1, thereby improving the safety and reliability of the device. The liquid level indicator can be connected to an automatic control system to realize automatic alarm or automatic drainage functions.
