Description

Technical Field

[0001] The invention relates to the technical field of rainwater recycling, in particular to a rainwater recycling and timely water-saving device for a roof garden. Background Art

[0002] A roof garden is a green landscape formed by planting flowers, trees or building various gardens on the top of a building. Roof gardens have various shapes and styles and can be designed according to specific needs and environmental characteristics to achieve the purpose of improving the ecological environment and improving the quality of life of residents.

[0003] The greening of roof gardens can absorb carbon dioxide in the air, release oxygen, help purify the air and reduce air pollution. Green vegetation can also reduce dust and noise pollution and improve the living environment of residents. Rainwater is one of the precious freshwater resources in nature. By recycling rainwater on roof gardens, a large amount of freshwater resources can be saved to meet the daily water needs of plants.

[0004] Currently, most of the existing rainwater recycling devices collect and store rainwater and use water pumps to directly recycle the rainwater to the plant roots, which is not conducive to the full utilization of rainwater and there is a large amount of rainwater waste. Therefore, it is necessary to propose a rainwater recycling and utilization and timely water-saving device for roof gardens. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a rainwater recycling and timely water-saving device for a roof garden, which realizes the recycling of rainwater through PVC pipelines, sponges, water storage barrels, rainwater collection barrels and water pumps, and uses the collected rainwater for water-saving irrigation, watering plants when they are short of water, and improving the utilization efficiency of rainwater.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a rainwater recycling and timely water-saving device for a roof garden, comprising a culture tank, a filtering component for filtering rainwater is provided in the culture tank, a rainwater collecting component for collecting rainwater is connected to the bottom of the culture tank, a water storage component for storing rainwater, replenishing domestic water and timely watering plants in the culture tank is connected to one side of the culture tank, and a pump component for connecting the rainwater collecting component and the water storage component is also provided on one side of the culture tank;

[0007] The invention is characterized in that: a water absorption component for absorbing water for plant roots is provided in the culture tank, a soil matrix is ​​laid in the culture tank, the water absorption component includes a PVC pipeline and a sponge, the sponge is evenly arranged in the soil matrix, the PVC pipeline is buried between the filter membrane and the filter stone, one end of the sponge is flush with the soil matrix, and the other end of the sponge extends to the water storage component through the PVC pipeline laid on the filter stone in the culture tank.

[0008] The principle of the basic scheme is: sponge is a porous material with excellent water absorption performance. A large number of tiny pores inside it can accommodate and absorb a large amount of water. When the sponge comes into contact with the water storage component, these pores will naturally attract and absorb water. After the sponge absorbs water, the water in its internal pores will form a certain water film or water column. These water columns will generate a certain negative pressure under the action of surface tension. This negative pressure enables the sponge to continuously absorb water from the water storage component until a certain equilibrium state is reached. At the same time, as the plant roots absorb and consume soil moisture, the soil moisture content in the culture tank decreases, and the dry soil absorbs the moisture in the sponge in time. The moisture in the sponge gradually decreases, and the negative pressure increases, thereby further driving the water from the water storage component to the sponge.

[0009] The beneficial effects of the basic scheme are: 1. By using rainwater collected on the roof for irrigation, the roof garden's dependence on external water sources is reduced, thus achieving water-saving irrigation.

[0010] 2. PVC pipes and sponges can evenly transport rainwater stored in the water storage components to the soil matrix, providing a stable water supply for plant roots. This continuous, appropriate and timely water supply helps the growth and development of plants, and improves the survival rate and growth quality of plants.

[0011] Furthermore, the filtration component includes a filtration membrane and a filtration stone, both of which are laid in the culture tank, and the filtration membrane is located between the soil matrix and the filtration stone.

[0012] The beneficial effect of the basic solution is that the filter membrane is laid between the soil matrix and the filter stone, and its small pore size can effectively intercept suspended matter, impurities, microorganisms, etc. in rainwater, which is beneficial to improve the cleanliness of the water entering the filter stone.

[0013] Furthermore, the rainwater collection component includes a rainwater collecting trough, which is fixedly connected to the outer wall of the culture tank. A number of through holes are opened between the rainwater collecting trough and the side wall of the culture tank. The rainwater collecting trough is connected to a rainwater collecting pipe. The other end of the rainwater collecting pipe is connected to a rainwater collecting barrel. The rainwater collecting barrel is located below the culture tank and the rainwater collecting trough.

[0014] The beneficial effects of the basic scheme are: the design of the rainwater collection tank is conducive to the smooth flow of rainwater on the roof into the rainwater collection tank. Rainwater filtered by the filter stone can enter the rainwater collection tank through the through hole, which is conducive to increasing the amount of rainwater collected. Using rainwater collection barrels to collect rainwater in the rainwater collection tank is conducive to the reuse of rainwater resources and reducing the waste of rainwater resources.

[0015] Furthermore, the pump assembly includes a water pump, which is fixedly connected to one side of the culture tank, the water inlet of the water pump extends to the bottom of the rainwater collection barrel, the water outlet of the water pump is connected to the water storage assembly, and the water pump is a wireless water pump.

[0016] The beneficial effect of the basic solution is that the water pump is conducive to pumping rainwater in the rainwater collection barrel into the water storage component, which is conducive to promoting the efficient transportation and recycling of rainwater, thereby meeting the growth needs of plants.

[0017] Furthermore, the water pump is covered with a waterproof casing.

[0018] The beneficial effects of the basic solution are: the waterproof shell helps to reduce the occurrence of water pump short circuits caused by rainwater penetration, and improves the stability and safety of water pump operation.

[0019] Furthermore, the water storage component includes a water storage barrel, which is connected to the water outlet of the water pump, one side of the top of the water storage barrel is connected to a water inlet valve, one side of the water inlet valve is connected to a water source, and one end of the sponge extends into the water storage barrel.

[0020] The beneficial effects of the basic solution are: through the connection between the water outlet of the water pump and the water storage barrel, rainwater can enter the water storage barrel quickly and efficiently, improving the storage efficiency of rainwater and reducing the loss and waste of rainwater during the collection process; through the design of the water inlet valve, if the collected rainwater cannot meet the water needs of the plants in the culture tank, the staff can add domestic water to the water storage barrel through the water inlet valve.

[0021] Furthermore, a water meter is fixedly connected between the water inlet valve and the water storage tank.

[0022] The beneficial effect of the basic solution is that the design of the water meter allows the staff to record the amount of water replenished by themselves, which is beneficial for the staff to record the supplementary irrigation.

[0023] Furthermore, the bottom wall of the culture tank is inclined, and the bottom wall of the culture tank on one side close to the rainwater collection tank is lower than the other side.

[0024] The beneficial effect of the basic scheme is that the bottom wall of the culture tank is inclined, which is conducive to the rainwater in the culture tank entering the rainwater collection tank through the through hole under the action of gravity, thereby improving the collection efficiency of rainwater in the culture tank.

[0025] Furthermore, a water level monitor is fixedly connected in the rainwater collection barrel, a controller is fixedly connected to the bottom of the water pump, the controller is connected to the water level monitor signal, and the controller is connected to the water pump.

[0026] The beneficial effect of the basic scheme is that when the water level in the rainwater collection barrel is too high, the controller starts the water pump to pump the water in the rainwater collection barrel into the water storage barrel, which helps to reduce the occurrence of rainwater overflow in the rainwater collection barrel.

[0027] Furthermore, the water storage barrel and the rainwater collection barrel are both made of translucent material.

[0028] The beneficial effect of the basic solution is that the translucent material allows the staff to observe the amount of water in the water storage barrel and the rainwater collection barrel in time, making it convenient for the staff to replenish the water in the water storage barrel.

[0035] The following is further described in detail through specific implementation methods:

[0036] Example:

[0037] Basically as attached Figure 1-Figure 5 As shown: A rainwater recycling and timely water-saving device for a roof garden, comprising a culture tank 1, a filtering component for filtering rainwater is provided in the culture tank 1, a rainwater collecting component for collecting rainwater is connected below the culture tank 1, one side of the culture tank 1 is connected to a water storage component for storing rainwater, replenishing domestic water, and timely watering plants in the culture tank, and one side of the culture tank 1 is also provided with a pump component for connecting the rainwater collecting component and the water storage component.

[0038] The invention is characterized in that: a water absorbing component for absorbing water for plant roots is provided in the culture tank 1, a soil matrix is ​​laid in the culture tank 1, the water absorbing component includes a PVC pipeline and a sponge, the sponge is evenly arranged in the soil matrix, one end of the sponge is flush with the soil matrix, and the other end of the sponge extends to the water storage component through a PVC pipeline laid on the filter stone in the culture tank 1.

[0039] The filter assembly includes a filter membrane and a filter stone, both of which are laid in the culture tank 1, and the filter membrane is located between the soil matrix and the filter stone. The rainwater collection assembly includes a rainwater collection tank 4, which is fixedly connected to the outer wall of the culture tank 1 by bolts, and a plurality of through holes 9 are opened between the rainwater collection tank 4 and the side wall of the culture tank 1. The rainwater collection tank 4 is connected to a rainwater collection pipe 3, and the other end of the rainwater collection pipe 3 is connected to a rainwater collection barrel 2, and the rainwater collection barrel 2 is located below the rainwater collection tank 4 of the culture tank 1. The inner bottom wall of the culture tank 1 is inclined, and the inner bottom wall of the culture tank 1 close to the rainwater collection tank 4 is lower than the other side.

[0040] The pump assembly includes a water pump 5, which is fixedly connected to one side of the culture tank 1 by bolts, a water inlet pipe of the water pump 5 extends to the bottom of the rainwater collection barrel 2, a water outlet of the water pump 5 is connected to the water storage assembly, and the water pump 5 is a wireless water pump. The water pump 5 is covered with a waterproof shell.

[0041] The water storage assembly includes a water storage barrel 8, which is connected to one end of the water outlet of the water pump 5, a water inlet valve 6 is connected to one side of the top of the water storage barrel 8, a water source is connected to one side of the water inlet valve 6, and one end of the sponge extends into the water storage barrel 8. A water meter 7 is fixedly connected between the water inlet valve 6 and the water storage barrel 8.

[0042] A water level monitor is fixedly connected to the rainwater collection barrel 2 by bolts, and a controller is fixedly connected to the bottom of the water pump 5 by bolts, and the controller is connected to the water level monitor signal, and the controller is connected to the water pump 5. The rainwater collection barrel 2 and the water storage barrel 8 are both made of translucent materials, and the translucent material is preferably polyethylene.

[0043] The specific implementation process is as follows: Plants are planted in the soil matrix of the culture tank 1. When rainwater falls on the roof and flows into the culture tank 1 of the roof garden, the rainwater will first contact the soil matrix. In this process, the plants absorb part of the water for growth through leaves and roots, and the soil matrix itself will also absorb and store part of the water. Then the remaining rainwater will continue to penetrate. When the rainwater passes through the filter membrane laid under the soil matrix, this membrane can effectively intercept impurities and fine particles in the soil, thereby keeping the water clean. Subsequently, the rainwater will flow through the filter stone, which will further purify the water and remove impurities in the rainwater. The purified rainwater eventually flows into the rainwater collection tank 4 through the through hole 9 between the side wall of the culture tank 1 and the rainwater collection tank 4, and eventually converges into the rainwater collection barrel 2 through the rainwater collection pipe 3.

[0044] As rainwater accumulates in the rainwater collection barrel 2, the water level monitor will continuously monitor the water level changes in the rainwater collection barrel 2. When the water level in the rainwater collection barrel 2 reaches a preset value, the water level monitor will send a signal to the controller. After receiving the signal, the controller will start the water pump 5. The water pump 5 extracts rainwater from the rainwater collection barrel 2 through the water inlet and sends the rainwater pump 5 to the water storage barrel 8 for storage through the water outlet. The waterproof shell can protect the water pump 5, reduce the damage to the water pump 5 caused by rainwater infiltration into the water pump 5, and improve the working stability of the water pump 5. When the water level in the rainwater collection barrel 2 is lower than the preset value, the controller will control the water pump 5 to turn off.

[0045] Since the rainwater collection barrel 2 and the water storage barrel 8 are both made of translucent materials, the staff can observe the water levels in the rainwater collection barrel 2 and the water storage barrel 8 at any time.

[0046] After the rainfall is completed, the water in the soil matrix will gradually evaporate and decrease over time. When the water content in the soil matrix decreases, the sponge will absorb water accordingly. After the sponge absorbs water, the water in its internal pores will form a certain water film or water column. These water columns will generate a certain negative pressure under the action of surface tension. This negative pressure enables the sponge to continuously absorb water from the water storage barrel 8 until a certain equilibrium state is reached. The negative pressure suction of the sponge is used to irrigate the plants, which is conducive to timely replenishment of water for the plants.

[0047] If there is no rainfall for a long time, or the rainfall is not enough to meet the needs of the plants, causing the water volume in the water storage barrel 8 to drop to a low level and insufficient to support normal irrigation needs, the staff can add domestic water to the barrel through the water inlet valve 6 on the top of the water storage barrel 8 to ensure the healthy growth of the plants. The water meter 7 fixedly connected between the water inlet valve 6 and the water barrel can help the staff accurately monitor the amount of water added and record it.
