Description

Technical Field

[0001] This utility model relates to the field of soft rainwater harvesting cellar technology, specifically a soft rainwater harvesting cellar with an irrigation system. Background Technology

[0002] A flexible rainwater harvesting cistern is a device used to collect and store rainwater. This device typically consists of multiple layers of flexible material, including a surface layer for collecting rainwater and a bottom layer for storing it. When it rains, the flexible material of the rainwater harvesting cistern quickly absorbs the rainwater to its surface, and its high elasticity and micropores filter out impurities and pollutants. Simultaneously, this material prevents water evaporation, keeping the stored rainwater clean and plentiful. In water-scarce areas, flexible rainwater harvesting cisterns play a vital role in agricultural irrigation.

[0003] In existing technologies, the installation of flexible rainwater harvesting cisterns typically involves first excavating a pool in the ground, with the pool depth 5cm less than the height of the cistern. The excavated soil is then used to create a slope around the pool. The water collection rings are fixed to the pool's perimeter with iron rods, and the outlet is fixed inside the intake pit. The outlet pipe is then protected with rigid PVC pipe before backfilling with soil. Next, the water collection surface is covered onto the sloped surface, and the rings are secured to the ground with iron rods. Finally, the water collection surface is covered onto the sloped surface, and the eyelets are secured to the ground with iron rods, completing the installation of the flexible rainwater harvesting cisterns.

[0004] However, when using the stored rainwater to irrigate crops, the existing soft rainwater collection cisterns require people to jump into the water pit to open the valve, put water into the water pit, and then manually draw water for irrigation. This irrigation method is time-consuming and labor-intensive. Moreover, when fertilization is required at the same time as irrigation, the fertilizer needs to be mixed and stirred manually after drawing water, making the fertilization process also very labor-intensive.

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a flexible rainwater harvesting cellar with an irrigation system, comprising: a flexible water cellar 1 and a ground surface 2. A pool body 3 and a water intake pit 5 are formed on the surface of the ground surface 2. The flexible water cellar 1 is disposed in the pool body 3. A water outlet pipe 6 is provided on the surface of the flexible water cellar 1, with the other end of the water outlet pipe 6 extending into the water intake pit 5. A valve 11 is fixed to the end of the water outlet pipe 6 extending into the water intake pit 5. A water collection surface 7 is provided at the top of the flexible water cellar 1, and a plurality of filter holes 9 are formed on the surface of the water collection surface 7. A concrete layer 10 is provided on the inner wall of the water intake pit 5. A top cover 19 is provided at the top opening. An irrigation connection pipe 26 is fixed on the surface of the top cover 19. A water pump 25 is installed at the bottom end of the irrigation connection pipe 26. A stirring rod 22 is rotatably connected to the surface of the top cover 19. The rod of the stirring rod 22 extends into the water intake pit 5 and is fixed with several sets of stirring plates 23. A fertilizer addition port 27 is opened on the surface of the top cover 19. A stirring motor 24 is fixed at the top of the top cover 19. A key is provided between the drive shaft of the stirring motor 24 and the stirring rod 22. A PVC pipe 4 is sleeved on the body of the water outlet pipe 6. Several eyelets 8 are provided around the water collection surface 7.

[0023] In actual use, firstly, a pool body 3 and a water intake pit 5 are opened on the surface of ground 2. At the same time, a trench for burying the water outlet pipe 6 is opened between the pool body 3 and the water intake pit 5. Then, the soft water cellar 1 is placed in the pool body 3, and the water outlet pipe 6 is passed through the PVC pipe 4 and laid in the trench. Then, the trench is filled. A water collection surface 7 is laid on the top of the soft water cellar 1, and the water collection surface 7 is fixed to the ground by passing long nails through the buttonholes 8. Then, concrete is applied to the inner wall of the water intake pit 5. After the concrete dries, a concrete layer 10 is formed to prevent the water discharged into the water intake pit 5 from being lost. Then, a top cover 19 is installed on the top of the water intake pit 5. An irrigation connection pipe 26 is installed on the surface of the top cover 19, and a water pump 25 is connected to the bottom end of the irrigation connection pipe 26. When it rains, rainwater drips onto the surface of the water collection surface 7 and flows into the soft water cellar 1 through the filter holes 9 and is stored. When irrigation is needed, connect the irrigation hose to the top of the irrigation connection pipe 26, then open valve 11 to release water from the flexible water cellar 1 into the water intake pit 5. The water is then pumped from the water intake pit 5 into the irrigation connection pipe 26 via pump 25, and finally into the irrigation hose. Workers only need to drag the end of the hose away from the irrigation connection pipe 26 and place the port near the crops to be irrigated to achieve irrigation in a time-saving and labor-saving manner. When fertilization is needed simultaneously with irrigation, open valve 11 to drain water from the flexible water cellar 1. After the water volume in the water intake pit 5 is sufficient, the valve 11 is closed. Then, fertilizer is added into the water intake pit 5 through the fertilizer inlet 27. At the same time, the stirring motor 24 is turned on. The drive shaft of the stirring motor 24 is connected by a key to drive the stirring rod 22 to rotate. The stirring rod 22 drives several sets of stirring plates 23 to rotate. The stirring plates 23 stir and mix the fertilizer and water in the water intake pit 5. After mixing, the water pump 25 is turned on to irrigate the crops. Fertilizer can be applied to the crops at the same time as irrigation, making fertilization very time-saving and labor-saving.

[0024] Example 2: Based on Example 1, in order to realize the installation of the top cover 19, a number of positioning grooves 28 are opened at the top of the ground 2, and a number of positioning rods 29 are fixed at the bottom of the top cover 19. The number of positioning rods 29 are respectively movably inserted into the number of positioning grooves 28.

[0025] Insert the positioning rods 29 at the bottom of the top cover 19 into the positioning grooves 28 at the top of the ground 2. Under the gravity of the top cover 19 and the various components installed on the top cover 19, the positioning rods 29 are pressed into the positioning grooves 28, thus realizing the installation of the top cover 19.

[0026] Example 3: Based on Example 2, in order to control the opening and closing of valve 11 without opening the top cover 19, valve 11 has a valve groove 12 inside, valve plate 13 is slidably connected in valve groove 12, valve 11 has a screw hole 14 at the top, valve stem 15 is rotatably connected in screw hole 14, valve stem hole 20 is opened on the surface of top cover 19, valve stem 15 is rotatably connected to the top of valve plate 13 at the bottom, and valve stem 15 passes through valve stem hole 20 and is fitted with handwheel 21 by screws.

[0027] Before the top cover 19 is installed, the handwheel 21 is separate from the valve stem 15. After the top cover 19 is installed, the top of the valve stem 15 extends through the valve stem hole 20 and out of the top of the top cover 19. Then, the handwheel 21 is installed on the top of the valve stem 15 with screws. When it is necessary to open the valve 11, simply stand on the top of the top cover 19 and turn the handwheel 21. The handwheel 21 drives the valve stem 15 to rotate. With the valve stem 15 and the screw hole 14 in a threaded connection state, the valve stem 15 moves upward and also moves the valve plate 13 upward in the valve groove 12, so that the fluid passage of the valve 11 is opened, thus opening the valve 11 without opening the top cover 19. Similarly, when it is necessary to close the valve 11, simply turn the handwheel 21 in the opposite direction. The valve stem 15 moves downward and drives the valve plate 13 downward in the valve groove 12, so that the fluid passage of the valve 11 is closed, thus closing the valve 11 without opening the top cover 19.

[0028] Example 4: Based on Example 3, in order to prevent impurities in the water intake pit 5 from flowing back into the soft water cellar 1 after the soft water cellar 1 and the water intake pit 5 are interconnected, a filter screen frame 16 is fixed at the outlet of the valve 11, a filter screen 17 is movably inserted into the filter screen frame 16, and a rubber ring 18 is fixed on the surface of the filter screen 17, with the rubber ring 18 abutting against the outlet of the valve 11.

[0029] A filter screen 17 is installed at the outlet end of valve 11. After valve 11 is opened and the soft water cellar 1 is connected to the water intake pit 5, it prevents impurities in the water intake pit 5 from flowing back into the soft water cellar 1 along with the water from the water intake pit 5. At the same time, the filter screen 17 is held in place at the port of valve 11 by the filter screen frame 16. The rubber ring 18 fixed on the surface of the filter screen 17 is compressed. The surface of the rubber ring 18 is relatively rough. The friction between the rubber ring 18 and the port of valve 11 can prevent the filter screen 17 from coming out of the filter screen frame 16. When the filter screen 17 needs to be cleaned, it can be removed from the top of the filter screen frame 16 by force. After cleaning, it can be reinstalled.

[0030] In actual use, firstly, a pool body 3 and a water intake pit 5 are opened on the surface of ground 2. At the same time, a trench for burying the water outlet pipe 6 is opened between the pool body 3 and the water intake pit 5. Then, the soft water cellar 1 is placed in the pool body 3, and the water outlet pipe 6 is passed through the PVC pipe 4 and laid in the trench. Then, the trench is filled. A water collection surface 7 is laid on the top of the soft water cellar 1. Several sets of iron rods 10 are inserted into several sets of aligned second pull rings 9 and first pull rings 8, and the iron rods 10 are driven into the ground 2. Then, concrete is applied to the inner wall of the water intake pit 5. After the concrete dries, a concrete layer 10 is formed to prevent the water discharged into the water intake pit 5 from being lost. Then, a top cover 19 is installed on the top of the water intake pit 5. An irrigation connection pipe 26 is installed on the surface of the top cover 19. The bottom end of the irrigation connection pipe 26 is connected to a water pump 25. When it rains, rainwater drips onto the surface of the water collection surface 7 and flows into the soft water cellar 1 through the filter holes 9 and is stored.When irrigation is needed, connect the irrigation hose to the top of the irrigation connection pipe 26, then open valve 11 to release water from the soft water cellar 1 into the water intake pit 5. The water is then pumped from the water intake pit 5 into the irrigation connection pipe 26 via pump 25, and finally into the irrigation hose. Workers only need to drag the end of the hose away from the irrigation connection pipe 26 and place the port near the crops to be irrigated for a time-saving and labor-saving irrigation process. When fertilization is needed simultaneously with irrigation, open valve 11 to drain water from the soft water cellar 1 into the water intake pit 5. Once the water volume is sufficient, close valve 11. Then, add fertilizer into the water intake pit 5 through the fertilizer inlet 27. Simultaneously, start the mixing motor 24, and the drive shaft of the mixing motor 24... The keyway drives the stirring rod 22 to rotate, which in turn drives several sets of stirring plates 23 to rotate. The stirring plates 23 mix the fertilizer and water in the water pit 5 evenly. After mixing, the water pump 25 is turned on to irrigate the crops, thus fertilizing the crops at the same time, making fertilization very time-saving and labor-saving. The positioning rods 29 at the bottom of the top cover 19 are inserted into the positioning grooves 28 at the top of the ground 2. Under the weight of the top cover 19 and the various components installed on it, the positioning rods 29 are pressed into the positioning grooves 28, thus realizing the installation of the top cover 19. Before the top cover 19 is installed, the handwheel 21 is in a separated state from the valve stem 15. After the top cover 19 is installed, the top of the valve stem 15 passes through... The valve stem 15 extends through the valve stem hole 20 to the top of the top cover 19, and then the handwheel 21 is installed on the top of the valve stem 15 using screws. When it is necessary to open the valve 11, simply stand on the top of the top cover 19 and turn the handwheel 21. The handwheel 21 drives the valve stem 15 to rotate. With the valve stem 15 threadedly connected to the screw hole 14, the upward movement of the valve stem 15 also moves the valve plate 13 upward in the valve groove 12, thus opening the fluid passage of the valve 11. This allows the valve 11 to be opened without opening the top cover 19. Similarly, when it is necessary to close the valve 11, simply turn the handwheel 21 in the opposite direction. The downward movement of the valve stem 15 drives the valve plate 13 downward in the valve groove 12, thus closing the fluid passage of the valve 11. The valve 11 is closed without opening the top cover 19. A filter screen 17 is installed at the outlet of the valve 11. After the valve 11 is opened and the soft water cellar 1 is connected to the water intake pit 5, the filter screen 17 prevents impurities in the water intake pit 5 from flowing back into the soft water cellar 1 along with the water from the water intake pit 5. At the same time, the filter screen 17 is held in place at the port of the valve 11 by the filter screen frame 16. The rubber ring 18 fixed on the surface of the filter screen 17 is compressed. The surface of the rubber ring 18 is relatively rough. The friction between the rubber ring 18 and the port of the valve 11 prevents the filter screen 17 from coming out of the filter screen frame 16. When the filter screen 17 needs to be cleaned, it can be removed from the top of the filter screen frame 16 by force. After cleaning, it can be reinstalled.
