Description

Technical Field

[0001] The invention relates to the technical field of garden ecological greening equipment, in particular to a rainwater collection and irrigation device for garden ecological greening. Background Art

[0002] In the process of landscaping maintenance and management, due to the season and the growth characteristics of plants, it is necessary to often water the greening away from the greening. At present, there are also a variety of devices or equipment for collecting rainwater in the rainy season. However, many of the current rainwater collection equipment are fixed installation forms, which are very easy to gather debris to block the pipes for recycling rainwater, and a large amount of manpower is required to maintain the equipment. In addition, the current rainwater collection equipment is not ecologically friendly enough. Large-scale rainwater collection causes the surrounding plants to be greatly affected by the amount of rainfall, light intensity and time, which makes the current rainwater collection equipment unable to maintain the landscaping ecologically.

[0003] To this end, the Chinese patent application with publication number "CN116235770A" discloses "a rainwater collection and irrigation device for garden ecological greening", whose main structure includes a storage mechanism, a collection mechanism, a relay mechanism, a traction mechanism and a locking mechanism. The rainwater collection and irrigation device for garden ecological greening adopts the method of installing the threaded steel frame on the garden foundation or the mobile frame, so that the rainwater collection and irrigation device for garden ecological greening has a wide range of applicability, avoiding the high cost construction problem caused by traditional pond water storage and underground pipe box water storage.

[0004] In actual use, rainwater will not only be mixed with some solid matter that can be filtered through the filter holes, but also some dust dissolved in the rainwater, which can easily pass through the filter holes. As the rainwater remains stationary for a long time, the sludge formed by some dust will settle inside the storage box, and eventually cause blockage of the pipes used to discharge rainwater. At the same time, rainwater with sludge will form deposits on the surface of the plants after watering them, which will also have a negative impact on the plants. Summary of the invention

At the same time, the precipitated sludge can be subjected to spiral feeding and filter pressing, so that the precipitated sludge can be separated from the rainwater, and the dust content in the rainwater is effectively reduced, so as to reduce the negative impact of the sludge formed by dust on the equipment.

[0018] 2. By setting up a rotating cleaning mechanism, the rotor will drive the special-shaped scraper to rotate, so that the sludge and debris attached to the inner wall of the rainwater storage chamber can be scraped off. At the same time, the spiral blades are rotating, which will cause the sludge and debris to move downward until the debris and sludge are continuously accumulated on the upper surface of the limit movable plate, and the spiral spring is continuously compressed.

[0019] 3. By setting up a cache-type drainage mechanism, rainwater is filtered through the impurity filtering holes and discharged into the pipe receiving rainwater through the lateral liquid flow holes. Once the pipe receiving rainwater suddenly stops the flow of liquid, a water hammer effect will occur. Since the elastic airbag is a sleeve structure made of rubber material with elastic extension and elastic retraction capabilities, at this time, the impact force of rainwater will cause the elastic airbag to expand outward, thereby alleviating the pressure of rainwater and realizing the cache-type discharge function of sewage.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 4A rainwater collection and irrigation device for garden ecological greening comprises a vertical liquid storage tank 1 equipped with a supporting leg 2, a rainwater storage chamber 3 arranged inside the vertical liquid storage tank 1, a bottom docking channel 4 integrally arranged at the bottom end of the rainwater storage chamber 3, a No. 1 component perforation 5 arranged at the top center of the vertical liquid storage tank 1, a vertical hollow tube 6 fixedly installed at the top center of the vertical liquid storage tank 1, a driving motor 8 fixedly installed at the top of the vertical hollow tube 6 through a driving motor mounting shell 7, a rotor 9 of the driving motor 8 penetrating the top of the vertical hollow tube 6, and a rainwater inlet 10 arranged at the top of the vertical liquid storage tank 1 and connected to the rainwater storage chamber 3. Rainwater enters the interior of the rainwater storage chamber 3 through the rainwater inlet 10 and is stored in the interior of the rainwater storage chamber 3. Due to long-term stillness, debris and dust in the rainwater will precipitate and adhere to the inner wall of the rainwater storage chamber 3. Starting the driving motor 8 can perform sludge removal.

[0031] To achieve targeted sludge removal, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , it is necessary to set up a rotating cleaning mechanism 11, which is provided with a special-shaped scraper 114 that rotates with the rotor 9 and can scrape the sludge attached to the inner wall of the rainwater storage chamber 3, a spiral blade 116 that can make the surrounding medium move downward when rotating, and a limit movable plate 117 that produces downward elastic movement after being subjected to a downward force. The rotor 9 will drive the special-shaped scraper 114 to rotate. Since the structural form of the special-shaped scraper 114 located on its outer side matches the structural form of the longitudinal section of the rainwater storage chamber 3, the sludge and debris attached to the inner wall of the rainwater storage chamber 3 can be scraped off. At the same time, the spiral blade 116 is rotating, and since the spiral blade 116 rotates with the rotor 9, the The medium around it produces a downward movement, which will cause the sludge and debris to move downward until the debris and sludge are continuously accumulated on the upper surface of the limiting movable plate 117. The accumulated sludge and impurities will form a downward force on the limiting movable plate 117, and cause the limiting movable plate 117 to move downward, while the coil spring 1111 is continuously compressed. The sludge and debris are in a tightly stacked state under the bidirectional force, and rainwater cannot leak out. When the amount of sludge and impurities exposed to the outside reaches a certain level, a stick is used to apply force to the sludge and impurities horizontally to push the sludge and impurities out. The coil spring 1111 will promptly reset the limiting movable plate 117, thereby clearing the sludge in a directional manner.

[0032] For the specific structure of the rotary cleaning mechanism 11, please refer to Figure 5, including a No. 1 rotating shaft 111 and a limiting movable plate 117 located inside the vertical hollow tube 6 and the No. 1 component through-hole 5, the top of the No. 1 rotating shaft 111 is provided with a No. 1 component fixing groove 112 for fixing and installing the rotor 9, the shaft body of the No. 1 rotating shaft 111 is installed inside the No. 1 component fixing groove 112 through a bearing, the bottom end of the No. 1 rotating shaft 111 is provided with a No. 2 rotating shaft 113 which is an integral structure with it and is located inside the rainwater storage chamber 3, the shaft body of the No. 2 rotating shaft 113 is fixedly installed with a special-shaped scraper strip 114 which rotates with it, and the bottom end of the No. 2 rotating shaft 113 is provided with a No. 2 rotating shaft 113 which is an integral structure with it and penetrates The third rotating shaft 115 passes through the bottom docking channel 4, and the shaft body of the third rotating shaft 115 is provided with a spiral blade 116 with an integral structure therewith. The limiting movable plate 117 is provided with three circular array-type No. 2 component through holes 118 in the plate body near its edge, and the interior of each of the No. 2 component through holes 118 is penetrated by a longitudinal limiting rod 119, and a top limiting plate 1110 is fixedly installed on the top end of the longitudinal limiting rod 119. The longitudinal limiting rod 119 is sleeved with a compressed spiral spring 1111 on the outer periphery of the shaft body between the limiting movable plate 117 and the top limiting plate 1110.

[0033] In order to achieve the function of caching sewage, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , it is necessary to set up a cache-type drainage mechanism 12, which is provided with an impurity filtering hole 127 for filtering debris and an elastic air bag 1212 that can relieve the impact of water pressure. The pipe docking port 1210 needs to be docked with the pipe receiving rainwater. The rainwater is filtered through the impurity filtering hole 127 and discharged into the pipe receiving rainwater through the horizontal liquid flow hole 129. Once the pipe receiving rainwater suddenly stops the flow of liquid, a water hammer effect will occur. Since the elastic air bag 1212 is a sleeve structure made of rubber material with elastic extension and elastic retraction capabilities, at this time, the impact force of rainwater will cause the elastic air bag 1212 to expand outward, thereby relieving the pressure of rainwater, and then realizing the cache-type discharge function of sewage.

[0034] For the specific structure of the cache type drainage mechanism 12, please refer to Figure 6, including a vertical hollow shell 121, the top of the vertical hollow shell 121 is provided with a No. 1 mounting plate structure 122 which is an integral structure with it and fixedly installed at the bottom of the bottom docking channel 4, the bottom end of the vertical hollow shell 121 is provided with a No. 2 mounting plate structure 123 which is an integral structure with it, the bottom end of the coil spring 1111 is in contact with the upper surface of the No. 2 mounting plate structure 123, the top of the coil spring 1111 is in contact with the bottom surface of the top limiting plate 1110, the No. 2 mounting plate structure 123 is in contact with the upper end surface of the limiting movable plate 117, the No. 3 component through-hole 124 corresponding to the No. 2 component through-hole 118 is provided in the plate body of the No. 2 mounting plate structure 123, the bottom end of the longitudinal limiting rod 119 is fixedly installed on the upper surface of the No. 2 mounting plate structure 123, and the center of the vertical hollow shell 121 is provided with an inner rain which is connected to the internal structure of the bottom docking channel 4 at the top and is in an open state at the bottom. The vertical hollow shell 121 is provided with an outer rainwater flow chamber 126 on the periphery of the inner rainwater flow chamber 125, and the inner rainwater flow chamber 125 and the outer rainwater flow chamber 126 are connected via a plurality of impurity filtering holes 127. A transverse liquid flow tube 128 having an integral structure therewith is provided in the middle of the outer circumferential surface of the vertical hollow shell 121, and a transverse liquid flow hole 129 connected to the outer rainwater flow chamber 126 is provided inside the transverse liquid flow tube 128, and a pipe docking port 1210 is provided at the port of the transverse liquid flow hole 129. An elastic air bag 1212 is fixedly installed on the outer circumferential surface of the transverse liquid flow tube 128 via a fixing ring 1213, and a rainwater buffer port 1211 connecting the transverse liquid flow hole 129 and the inner surface area of ​​the elastic air bag 1212 is provided on the circumferential surface of the transverse liquid flow tube 128.

[0035] To collect rainwater over a large area according to actual conditions, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8, it is necessary to set up an openable rainwater collecting mechanism 13, which is provided with a tarpaulin 133 inside which can guide rainwater into the rainwater filling port 10 after being opened, a hollow insertion pile 136 that can be inserted into the ground and has a supporting effect on the edge of the tarpaulin 133, and an elastic rubber sheet 1312 embedded in the circumferential surface of the hollow insertion pile 136 and expands outward after being subjected to gas pressure, thereby increasing the friction between the rubber sheet and the soil. On rainy days, the tarpaulin 133 is unfolded, and then the hollow insertion pile 136 is inserted into the ground, and then the gas storage chamber 138 is filled with gas through the gas inlet channel 1313 using an inflatable device. The high-pressure gas is filled into the part, and the high-pressure gas will make the elastic rubber sheet 1312 expand outward and contact the corresponding soil, thereby increasing the stability of the hollow inserted pile 136. When it needs to be taken out, the high-pressure gas can be released through the air valve. After rainwater falls on the tarpaulin 133, since the horizontal height of the tarpaulin 133 near the vertical liquid storage tank 1 is lower than the horizontal height of the tarpaulin far away from the vertical liquid storage tank 1, the rainwater will flow into the rainwater inlet 10, realizing a large-area collection of rainwater, and on sunny days, the tarpaulin 133 can be folded up so as not to occupy the light area for surrounding plants.

[0036] For the specific structure of the open and close rainwater collection mechanism 13, please refer to Figure 7 and Figure 8 , comprising an embedded ring body 131 fixedly mounted at the top edge of the vertical liquid storage tank 1, a ring mouth structure 132 for rainwater flow is arranged at the center of the embedded ring body 131, a rain cloth 133 is embedded in the outer circumferential surface of the embedded ring body 131, a plurality of annular array-type fixed heads 134 are fixedly mounted at the edge of the rain cloth 133, a longitudinal support rod 135 is fixedly mounted at the bottom end of each of the fixed heads 134, a hollow insertion pile 136 is fixedly mounted at the bottom end of each of the longitudinal support rods 135, a tip structure 137 which is an integral structure with the hollow insertion pile 136 and extends downward is arranged at the bottom of the hollow insertion pile 136, a gas storage Cavity 138, a plurality of gas flow ports 1311 in an annular array and connected to the gas storage cavity 138 are arranged at the circumferential wall thickness of the hollow inserted pile 136, an elastic rubber sheet 1312 is closed and embedded in the outer end face of each gas flow port 1311 of the hollow inserted pile 136, a No. 2 gas flow hole 1310 connected to the top of the gas storage cavity 138 is arranged at the top of the hollow inserted pile 136, a No. 1 gas flow hole 139 connected to the No. 2 gas flow hole 1310 is arranged inside the longitudinal support rod 135, and a gas inlet channel 1313 connected to the No. 1 gas flow hole 139 and equipped with a gas valve is arranged on the circumferential surface of the longitudinal support rod 135.

[0037] The specific working principle of the present invention is to connect the pipe docking port 1210 with the pipe receiving rainwater, unfold the rain sheet 133 on rainy days, and then insert the hollow insertion pile 136 into the ground, and then use the inflation device to fill the gas storage chamber 138 with high-pressure gas through the gas inlet channel 1313. The high-pressure gas will make the elastic rubber sheet 1312 expand outward and contact with the corresponding soil, thereby increasing the stability of the hollow insertion pile 136. After the rainwater falls on the rain sheet 133, since the horizontal height of the rain sheet 133 at the part close to the vertical liquid storage tank 1 is lower than the horizontal height of the part away from the vertical liquid storage tank 1, the rainwater will flow into the rainwater inlet 10.

[0038] Rainwater enters the rainwater storage chamber 3 through the rainwater inlet 10 and is stored in the rainwater storage chamber 3. Due to long-term static state, debris and dust in the rainwater will precipitate and adhere to the inner wall of the rainwater storage chamber 3, and the drive motor 8 is started;

[0039] The rotor 9 will drive the special-shaped scraper strip 114 to rotate, so that the sludge and debris attached to the inner wall of the rainwater storage chamber 3 can be scraped off. At the same time, the spiral blade 116 is rotating, so that the medium located around it will move downward, and the sludge and debris will move downward until the debris and sludge are continuously accumulated on the upper surface of the limit movable plate 117. The accumulated sludge and impurities will form a downward force on the limit movable plate 117, and the limit movable plate 117 will move downward, and the spiral spring 1111 will be continuously compressed. Under the bidirectional force, the sludge and debris are in a tightly accumulated state, and the rainwater cannot leak out. When the amount of sludge and impurities exposed to the outside reaches a certain extent, a stick is used to apply force to the sludge and impurities horizontally, so that the sludge and impurities are pushed out, and the spiral spring 1111 will promptly reset the limit movable plate 117, thereby clearing the sludge in a directional manner;

[0040] Rainwater is filtered through the impurity filtering hole 127 and discharged into the pipe receiving rainwater through the transverse liquid flow hole 129. Once the pipe receiving rainwater suddenly stops the flow of liquid, a water hammer effect will occur. Since the elastic airbag 1212 is a sleeve structure made of rubber material with elastic extension and elastic retraction capabilities, the impact force of rainwater will cause the elastic airbag 1212 to expand outward, thereby alleviating the pressure of rainwater and realizing the buffer discharge function of sewage.

[0041] On sunny days, the tarpaulin 133 can be folded up so as not to occupy the illumination area of ​​the surrounding plants.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
