Description
Technical Field
[0001] This utility model relates to the field of rainwater harvesting, and in particular to an environmentally friendly and energy-saving rainwater harvesting device for building construction. Background Technology
[0002] At construction sites, water accumulation can make the ground muddy and affect the construction process. This problem is particularly serious at construction sites that lack drainage facilities, where rainwater harvesting devices are needed to collect rainwater.
[0003] A rainwater collection device for building construction disclosed in Chinese Utility Model 2 (Announcement No.: CN215367538U) includes a base, a water collection tank at the top of the base, a water outlet pipe extending to the bottom of the base on the inner bottom wall of the water collection tank, and a water collection hopper extending to the top of the inner top wall of the water collection tank. A strip plate is arranged between the left and right sides of the inner wall of the water collection tank. A filter assembly, slidably connected to the strip plate and extending to the right side of the water collection tank, is arranged on the left side of the inner wall of the water collection tank, above the strip plate. This rainwater collection device allows for downward movement of the filter screen by pulling down a pull ring, which moves a slider downwards and compresses a return spring. Pulling a pull rope, supported by a pulley, rotates a shaft, which in turn rotates a gear, causing a toothed plate to move downwards. This moves a moving block, disengaging a locking block from a rectangular block, allowing the rectangular block to be moved to the right to remove the filter screen. This achieves the purpose of detaching the filter screen for cleaning.
[0004] In the process of developing this utility model, the inventors discovered at least the following problems with the technology: when the water collection hopper in the aforementioned rainwater harvesting device is too small, the rainwater collection efficiency is low; when the water collection hopper is too large, it is not conducive to the turnover of the entire device. Therefore, an environmentally friendly and energy-saving rainwater harvesting device for building construction is now proposed. Utility Model Content
[0005] In order to improve rainwater collection efficiency and facilitate the turnover of the entire device, this utility model provides an environmentally friendly and energy-saving rainwater collection device for building construction.
[0006] This utility model provides an environmentally friendly and energy-saving rainwater collection device for building construction, which adopts the following technical solution:
[0007] An environmentally friendly and energy-saving rainwater collection device for building construction includes a collection cloth and a support pole. The support pole is installed around the periphery of the collection cloth. The middle part of the collection cloth is concave. A curved pipe is fixedly installed in the middle of the collection cloth. A vertical pipe is fixedly installed at the bottom of the curved pipe. A filter assembly is installed inside the vertical pipe. A drain pipe is fixedly installed on the side of the bottom of the vertical pipe. Several stabilizing components are installed at the bottom of the collection cloth.
[0008] By adopting the above technical solution, the canopy structure composed of poles and collecting cloth provides a large rainwater collection area, improving rainwater collection efficiency. Moreover, the stable component setup enhances the wind resistance of the collecting cloth, reducing the impact of wind on rainwater collection. Furthermore, the detachable structure between the poles and the collecting cloth, as well as the foldable nature of the collecting cloth itself, facilitates turnover and reuse. The entire device requires no electricity, and the cost of the parts and materials required for the device itself is low.
[0009] Optionally, the bottom of the pole is designed as a pointed cone, and a stabilizing plate is fixedly installed at the bottom of the pole, with a through hole on the stabilizing plate.
[0010] By adopting the above technical solution, the pointed cone shape at the bottom of the pole facilitates the pole's penetration into the ground. Furthermore, by passing the anchor rods through the through holes on the stabilizing plate and connecting them to the ground, the pole can be stably fixed, thereby ensuring the stability of the overall structure.
[0011] Optionally, a strap is fixedly installed around the periphery of the collecting cloth, and a binding ring is fixedly installed at the top of the upright, with the strap tied to the binding ring.
[0012] By adopting the above technical solution, the connection between the collection cloth and the upright is achieved through straps and rings, which facilitates the assembly and disassembly of the collection cloth and the upright.
[0013] Optionally, the filter assembly includes a threaded connector and a filter cartridge, the filter cartridge being fixedly mounted on the threaded connector, the threaded connector being threaded to the bottom of the vertical pipe, and the filter cartridge being located inside the vertical pipe.
[0014] By adopting the above technical solution, the threaded connector and the vertical pipe are connected by threads. When there are too many impurities inside the filter cartridge, the filter cartridge can be easily cleaned by rotating the threaded connector to remove it from the inside of the vertical pipe.
[0015] Optionally, the outer diameter of the filter cartridge is adapted to the inner diameter of the vertical pipe.
[0016] By adopting the above technical solution, it is less likely that there will be excessive gaps between the outer surface of the filter cartridge and the inner wall of the vertical pipe, so that rainwater flowing out of the bend can flow smoothly into the interior of the filter cartridge, thereby improving the filtration effect of rainwater.
[0017] Optionally, the stabilizing component includes a connecting rope, a connecting plate, and a fixing nail. Both ends of the connecting rope are fixedly connected to the collecting cloth, and the connecting plate is fixedly installed in the middle of the connecting rope. A through hole is opened in the middle of the connecting plate, and the fixing nail passes through the interior of the through hole.
[0018] By adopting the above technical solution, the fixing nails are passed through the through holes in the connecting plate and connected to the ground, so that the connecting rope can pull and fix the collection cloth, which helps to improve the wind resistance of the entire shed and reduce the impact of wind and rainwater collection.
[0019] Optionally, a sunshade net is fixedly connected to the upper surface of the collecting cloth.
[0020] By adopting the above technical solution, the installation of the sunshade net avoids direct sunlight on the surface of the collection cloth, which helps to extend the service life of the collection cloth. In addition, it also facilitates the placement of building materials under the collection cloth or allows workers to rest under the collection cloth.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. This utility model has a large rainwater collection area and improves rainwater collection efficiency by constructing a canopy structure composed of uprights and collection cloth. Moreover, the setting of stable components improves the wind resistance of the collection cloth and reduces the impact of wind on rainwater collection. At the same time, the detachable structure between the uprights and the collection cloth and the foldable performance of the collection cloth itself are conducive to turnover and reuse. Furthermore, the entire device does not require electricity and the cost of the parts and materials required by the device itself is low.
[0023] 2. This utility model avoids direct sunlight on the surface of the collecting cloth by setting up a sunshade net, which helps to extend the service life of the collecting cloth. It can also be used as a place to store building materials or a temporary rest place for workers, making it highly practical. Attached Figure Description

[0030] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] Please refer to Figure 1 and Figure 3 An environmentally friendly and energy-saving rainwater collection device for building construction includes a collection cloth 1 and a support pole 2. The collection cloth 1 is waterproof, and the support pole 2 is installed around the perimeter of the collection cloth 1. The support pole 2 and the collection cloth 1 together form a rainwater collection canopy structure. The bottom of the support pole 2 has a pointed cone design, and a stabilizing plate 6 is fixedly installed at the bottom of the support pole 2. The stabilizing plate 6 has a through hole 7. The pointed cone shape of the bottom of the support pole 2 facilitates the support pole 2 to penetrate deep into the ground. By passing anchor rods or the like through the through hole 7 on the stabilizing plate 6 and connecting it to the ground, the support pole 2 can be stably fixed, thereby ensuring the stability of the overall structure. The perimeter of the collection cloth 1 is fixedly installed with straps 8, and the top of the support pole 2 is fixedly installed with a binding ring 9. The straps 8 are tied to the binding ring 9, and the connection between the collection cloth 1 and the support pole 2 is achieved through the straps 8 and the binding ring 9, facilitating the assembly and disassembly of the collection cloth 1 and the support pole 2. A sunshade net 16 is fixedly connected to the upper surface of the collecting cloth 1. The setting of the sunshade net 16 avoids direct sunlight on the surface of the collecting cloth 1, which helps to extend the service life of the collecting cloth 1. In addition, it is also beneficial for building materials to be placed under the collecting cloth 1 or for workers to rest under the collecting cloth 1.
[0032] Reference Figure 1 and Figure 2The collecting cloth 1 has a concave center, and a curved pipe 3 is fixedly installed in the center of the collecting cloth 1. A vertical pipe 4 is fixedly installed at the bottom of the curved pipe 3. A filter assembly is installed inside the vertical pipe 4, and a drain pipe 5 is fixedly installed on the side of the bottom of the vertical pipe 4. When it rains, the collecting cloth 1 collects the rainwater. The rainwater flows from the curved pipe 3 in the center of the collecting cloth 1 into the vertical pipe 4. The filter assembly filters the rainwater, and finally, it is discharged into an external storage container through the drain pipe 5. Specifically, the filter assembly includes a threaded connector 10 and a filter cartridge 11. The filter cartridge 11 is fixedly installed on the threaded connector 10, which is threaded to the bottom of the vertical pipe 4. The filter cartridge 11 is located inside the vertical pipe 4, and the threaded connector 10 is threaded to the vertical pipe 4. When there are too many impurities inside the filter cartridge 11, the filter cartridge 11 can be removed from the inside of the vertical pipe 4 by rotating the threaded connector 10, which makes it easy to clean the filter cartridge 11. The outer diameter of the filter cartridge 11 is matched with the inner diameter of the vertical pipe 4. This structure makes it less likely that there will be a large gap between the outer surface of the filter cartridge 11 and the inner wall of the vertical pipe 4, so that the rainwater flowing out from the bend pipe 3 can flow smoothly into the interior of the filter cartridge 11, thereby improving the filtration effect of rainwater.
[0033] Reference Figure 1 and Figure 4 The bottom of the collecting cloth 1 is equipped with several stabilizing components, including a connecting rope 12, a connecting plate 13, and a fixing nail 14. Both ends of the connecting rope 12 are fixedly connected to the collecting cloth 1, and the middle part of the connecting rope 12 hangs freely. The connecting plate 13 is fixedly installed in the middle of the connecting rope 12. A through hole 15 is opened in the middle of the connecting plate 13, and the fixing nail 14 passes through the inside of the through hole 15. By passing the fixing nail 14 through the through hole 15 on the connecting plate 13 and connecting it to the ground, the connecting rope 12 pulls and fixes the collecting cloth 1, which helps to improve the wind resistance of the entire shed and reduces the impact of wind and rainwater collection.
[0034] The implementation principle of this utility model is as follows: In use, by passing the fixed anchor rod through the through hole 7 on the stabilizing plate 6 and connecting it to the ground, the upright 2 is stably fixed. Then, the binding strap 8 on the collecting cloth 1 is tied to the binding ring 9 on the upright 2 to achieve the construction of the rain collection shed. Finally, by passing the fixing nail 14 through the through hole 15 on the connecting plate 13 and connecting it to the ground, the connecting rope 12 pulls and fixes the collecting cloth 1, which helps to improve the wind resistance of the entire shed and reduces the impact of wind and rainwater collection. When it rains, the collecting cloth 1 collects the rainwater. The rainwater flows from the curved pipe 3 in the middle of the collecting cloth 1 into the interior of the vertical pipe 4. The filter assembly filters the rainwater and finally discharges it to the external storage container through the drain pipe 5. During the rainwater collection process, when it is necessary to clean the debris inside the filter cylinder 11 in the filter assembly, the filter cylinder 11 can be removed from the interior of the vertical pipe 4 by rotating the threaded connector 10, which makes it easy to clean the filter cylinder 11.
[0035] Moreover, when it is a sunny day, the sunshade net 16 is fixedly connected to the upper surface of the collecting cloth 1, which avoids direct sunlight on the surface of the collecting cloth 1, which helps to extend the service life of the collecting cloth 1. It also facilitates the placement of building materials under the collecting cloth 1 and allows workers to rest under the collecting cloth 1, thus improving the practicality of the entire rain collection shed.
[0036] In summary, the canopy structure composed of the uprights 2 and the collecting cloth 1 provides a large rainwater collection area, improving rainwater collection efficiency. Furthermore, the stable components enhance the wind resistance of the collecting cloth 1, reducing the impact of wind on rainwater collection. The detachable structure between the uprights 2 and the collecting cloth 1, along with the foldable nature of the collecting cloth 1 itself, facilitates turnover and reuse. The entire device requires no electricity, and the cost of its parts and materials is low. Additionally, after the canopy is constructed, a sunshade net 16 is installed on the collecting cloth 1, preventing direct sunlight from reaching its surface and extending its lifespan. It can also serve as a storage area for building materials or a temporary rest area for workers, demonstrating its strong practicality.
