[0031] In the above technical scheme, the water collection and fertilizer dissolving system includes a water collection pool for collecting rainwater and a water tank connected to the water collection pool, and a fertilizer dissolving tank 14 for mixing the water in the water tank with fertilizer, which can be installed with an existing fertilizer dissolving tank 14, and the fertilizer dissolving tank 14 includes a cylindrical shell and a stirring shaft 15 arranged in the cylindrical shell, and a stirring blade provided on the stirring shaft 15 and a motor 17 for driving the stirring shaft 15 to rotate. The upper end water inlet of the fertilizer dissolving tank 14 is connected with the water tank through a water inlet pipe 19 to obtain the water in the water tank, and the feeding port 18 provided at the upper end of the fertilizer dissolving tank 14 is used to add fertilizer as needed. The bottom of the fertilizer dissolving tank 14 is provided with a discharge port 16, and the discharge port 16 is provided with a valve for controlling opening and closing. The discharge port 16 can be connected to a drip irrigation belt or a spraying device to drip or spray the water and fertilizer in the fertilizer dissolving tank 14 onto the vegetation in the planting area, thereby achieving fertilization and irrigation of the required vegetation;

[0032] The water collection pool is a water collection pool with an upper opening formed by pouring a waterproof wall 1 on the roof of the inclined plane (that is, the roof plate 3 is the bottom wall of the water collection pool, the plane of the roof is high on one side and low on the other side. In actual use, the angle between the roof plate 3 and the horizontal plane can be 1-10 degrees, and the upper end surface of the waterproof wall 1 is flush to form a water collection pool with an inclined bottom wall). The water tank is located below the water collection pool, and the fertilizer dissolving tank 14 is located below the water tank. The water collection pool and the water tank on the roof can be firmly supported by pouring support columns 20 and support beams. The fertilizer dissolving tank 14 is placed flat on the ground through the base; the water inlet at the upper end of the fertilizer dissolving tank 14 is connected to the bottom or middle of the water tank through the water inlet pipe 19, and a valve is provided on the water inlet pipe 19 to control the water in the water tank to flow into the fertilizer dissolving tank 14. The fertilizer dissolving tank 14 is located below the water tank, and the bottom or middle of the water tank is higher than the upper end of the fertilizer dissolving tank 14. No water pump is required. It is only necessary to control the valve on the water inlet pipe 19 to open, that is, the water in the water tank can flow into the fertilizer dissolving tank 14 for use; a water pump is provided on the high side of the inclined plane of the roof. The water outlet is connected to the water tank, and the water outlet can be installed on the roof board 3 on the high side of the roof inclined plane, or the bottom wall of the water outlet is flush with the roof board 3 and is installed on the waterproof fence 1. The water outlet shown in the figure is the bottom wall of the first water outlet 22, and the bottom wall of the second water outlet is flush with the roof board 3 and is installed on the waterproof fence 1. A low-level drain outlet 8 is installed on the roof board 3 on the low side of the roof inclined plane. A filter cover 6 can be detachably installed on the low-level drain outlet 8. The filter cover 6 is covered on the low-level drain outlet 8 to filter dead branches and fallen leaves for the low-level drain outlet 8. Leaves and other impurities can then pass through the low-level drain outlet 8, and silt, settled soil, sand, etc. can pass through the filter cover 6. A first stainless steel ball 7 that can sink to the bottom of the water is provided in the filter cover 6. The diameter of the first stainless steel ball 7 is larger than the diameter of the low-level drain outlet 8. The upper end surface of the low-level drain outlet 8 is a trumpet shape with a larger upper part and a smaller lower part, which is conducive to the first stainless steel ball 7 falling into the low-level drain outlet 8. When the first stainless steel ball 7 covers the low-level drain outlet 8, the first stainless steel ball 7 can seal the low-level drain outlet 8.

[0033] When the present invention is used, the first stainless steel ball 7 is placed on the trumpet-shaped low-level drain outlet 8, and covers and seals the low-level drain outlet 8 under the action of gravity and water pressure. The water collection pool on the roof continuously collects rainwater. When the water level reaches the outlet position, the water body can flow into the water tank through the outlet and be continuously collected. Since the bottom wall of the water collection pool is an inclined surface, the bottom wall of the water collection pool is also the inclined plane of the roof, and the outlet is arranged on the high side of the inclined plane of the roof. In the process of collecting rainwater in the water collection pool, the sediment is easily gathered to the low side of the inclined plane of the roof, reducing the sediment from flowing into the water tank, and the sediment is gathered on the other side, which is conducive to discharge and cleaning from the low-level drain outlet 8, thereby improving the use effect.

[0034] The collecting pool collects rainwater over a period of time, and the water level of the water body flowing into the water tank is higher than the top of the fertilizer dissolving tank 14 until the water tank is filled with water. When the fertilizer dissolving tank 14 needs water body fertilizer dissolving irrigation, the valve on the water inlet pipe 19 is opened, and the water body in the water tank can be flowed into the fertilizer dissolving tank 14 for use, without the need for a water pump, thereby reducing energy consumption. When the water added in the fertilizer dissolving tank 14 reaches the required water level, the required amount of fertilizer is added from the feed port 18 of the fertilizer dissolving tank 14, the motor 17 is started, and the stirring shaft 15 and the stirring blade are driven to rotate, so that the fertilizer added is dissolved with the water body added to obtain water fertilizer, the discharge port 16 of the fertilizer dissolving tank 14 is communicated with the drip irrigation belt or the spraying equipment on the planting ground, and the valve on the discharge port 16 is opened, so that the water fertilizer can be drip irrigated or sprayed on the vegetation in the planting ground, realizing fertilizing and irrigation of required vegetation, energy saving, water saving, convenient and practical.

[0035] On the basis of the above implementation, the outer periphery of the first stainless steel ball 7 is covered with a rubber layer, which is beneficial to the sealing effect of the low-position drain outlet 8.

[0036] On the basis of the above implementation, a drainage and silt removal device is also included, and the drainage and silt removal device includes:

[0037] A high-level drain outlet 4 is provided on the waterproof enclosure 1 near and directly above the low-level drain outlet 8. The position of the high-level drain outlet 4 is higher than the position of the water outlet on the opposite waterproof enclosure 1 (see the figure, the high-level drain outlet 4 is located above the first water outlet 22 and the second water outlet). The openings at both ends of the high-level drain outlet 4 are smoothly transitioned, and the end of the high-level drain outlet 4 away from the low-level drain outlet 8 is connected to a first vertically downward drain pipe 9;

[0038] The ear plate 5 is provided on the waterproof enclosure 1 near the low drain outlet 8 and directly above the high drain outlet 4. It is preferably provided in the filter cover 6, or is flush with the filter cover 6, or is fixedly connected to the filter cover 6. The ear plate 5 is provided with a vertically extending smooth through hole for limiting and guiding the movement of the first stainless steel ball 7. The filter cover 6 has a smooth through hole corresponding to the through hole of the ear plate 5.

[0039] The second stainless steel ball 11 has a diameter equal to or greater than the diameter of the first stainless steel ball 7 and a weight less than the weight of the first stainless steel ball 7. The second stainless steel ball 11 is slidably set in the first drain pipe 9. The second stainless steel ball 11 is fixed at one end of the traction rope 10, and the first stainless steel ball 7 is fixed at the other end. The traction rope 10 is slidably passed through the through hole of the filter cover 6, the through hole of the ear plate 5 and the high-level drain outlet 4, and the first stainless steel ball 7 and the second stainless steel ball 11 are pulled on both sides of the waterproof wall 1; the second stainless steel ball 11 is located below the first stainless steel ball 7, and the inner diameter of the first drain pipe 9 is 1-5 cm larger than the diameter of the second stainless steel ball 11.

[0040] The utility model sets the second stainless steel ball 11 to pull the first stainless steel ball 7. When the water tank is full of water and it rains continuously, the water level of the water collection pool continues to rise. When the water level reaches the high-level drain outlet 4, the rainwater flows out from the high-level drain outlet 4. Since the inner diameter of the first drain pipe 9 is 1-5 cm larger than the diameter of the second stainless steel ball 11, part of the water flowing into the first drain pipe 9 flows downward from the gap between the second stainless steel ball 11 and the first drain pipe 9, giving the second stainless steel ball 11 a downward force, and most of the water stays on the second stainless steel ball 11. Since the second stainless steel ball 11 is located below the first stainless steel ball 7 and has a larger diameter, it is subjected to a relatively large water pressure. When the water pressure and gravity exerted on the second stainless steel ball 11 are greater than those exerted on the first stainless steel ball 7, the first stainless steel ball 7 can be pulled up a certain distance, and the low-level drain outlet 8 is opened, so that the sediment sludge at the bottom of the sump flows out from the low-level drain outlet 8 along with the water flow; after a period of drainage, when the water level drops and the water pressure and gravity exerted on the second stainless steel ball 11 are less than those exerted on the first stainless steel ball 7, the first stainless steel ball 7 falls to the low-level drain outlet 8 again, and the low-level drain outlet 8 is closed, and the water level rises. This process is repeated, which is conducive to the discharge and cleaning of the sediment sludge at the bottom of the sump, and reduces the difficulty of manual regular cleaning.

[0041] Based on the above implementation method, a second drain pipe is connected below the high-level drain outlet 4. The lower ends of the first drain pipe 9 and the second drain pipe are combined to form a collecting pipe 12, which is located directly above the drainage trough 13 and is used to direct the silt and water discharged from the first drain pipe 9 and the second drain pipe to the required place.

[0042] On the basis of the above implementation method, two water tanks are arranged side by side, namely the first water tank 21 and the second water tank 25; two water inlets are correspondingly arranged, namely the first water inlet and the second water inlet; the first water inlet of the first water tank 21 and the second water inlet of the second water tank 25 are separated by a partition plate 26, the first water inlet and the second water inlet are located on the water tank side and are connected to the first water tank 21 through the first pipe 23, and the second water inlet is connected to the second water tank 25 through the second pipe 29; the first water inlet and the second water inlet are located on the water collection tank side and are provided with a filter enclosure 2, the filter enclosure 2 is a cylindrical or square box, one end opening of the filter enclosure 2 is connected to the first water inlet and the second water inlet, and the other end opening is provided with a slot 28, the slot 28 is used for detachably inserting a filter net or a barrier plate, and the space 27 formed in the enclosure is conducive to the flow of water on the two water inlets and reduces external interference. When the water tank is storing rainwater from the sump, a filter screen is inserted into the slot 28 on the filter enclosure 2 to filter the water flowing into the water tank from the sump; when the sump is manually cleaned regularly, the filter screen on the filter enclosure 2 can be pulled out and replaced with a barrier plate to prevent sewage, silt, etc. from being manually cleaned from the sump from flowing into the tank.

[0043] Based on the above implementation method, the bottom walls of the first water tank 21 and the second water tank 25 are both set to be funnel-shaped, and a third drain pipe 24 is set at the lowest end of the funnel-shaped bottom wall. A valve for controlling opening and closing is provided on the third drain pipe 24, which is conducive to the collection and cleaning of water sediment in the water tank.

[0044] Based on the above implementation, Figure 3 、 Figure 4 As shown, a limiting baffle 30 is provided on one of the first water inlet or the second water inlet, and the limiting baffle 30 blocks 1 / 3 to 1 / 2 of the vertical height of one of the water inlets, so that when rainwater is collected, the box without the limiting baffle 30 is filled with water first, which is convenient for use.

[0045] Based on the above implementation, Figure 3 、 Figure 4As shown, the first stainless steel ball 7 is provided with a plurality of stirring rods 31, one end of each stirring rod 31 being fixed to the first stainless steel ball 7, and the other end extending to the periphery of the water collection pool, and the other end of each stirring rod 31 being at a distance of more than 50 cm from the water inlet; the plurality of stirring rods 31 passing through the filter cover 6 is provided with a chute for the plurality of stirring rods 31 to move up and down, and the plurality of stirring rods 31 can all be submerged in water and laid flat on the roof. When the first stainless steel ball 7 is pulled up and down by the second stainless steel ball 11, one end of each stirring rod 31 moves up and down following the first stainless steel ball 7, thereby disturbing the sediment and sludge at the bottom of the water collection pool and improving the effect of discharging and cleaning the sediment and sludge at the bottom of the water collection pool.

[0046] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiment. They can be applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
