Abstract
Description
Technical Field
[0001] This application relates to the field of gutter drainage technology, and in particular to a drainage structure adapted to large-section gutters. Background Technology
[0002] A greenhouse, also known as a hothouse, is a structure that allows light to pass through and provides insulation or heating. Types of greenhouses include planting greenhouses, breeding greenhouses, exhibition greenhouses, experimental greenhouses, catering greenhouses, and entertainment greenhouses. The design of a greenhouse system includes heating systems, insulation systems, cooling systems, ventilation systems, control systems, and irrigation systems.
[0003] In the construction of greenhouses, a gutter drainage structure is installed on the top of the greenhouse. During rainy weather, rainwater will fall into the gutter along the greenhouse, and then into the drainage pipe, from where it will be discharged.
[0004] In the existing gutter drainage system, due to the presence of leaves and other debris on the roof of the greenhouse, rainwater washes the debris into the drainage ditch and eventually into the drainage outlet. When there is a lot of debris, it can clog the drainage pipes and affect drainage efficiency. Utility Model Content
[0005] The purpose of this application is to address the problem that existing gutter drainage systems, due to the presence of leaves and other debris on the roof of greenhouses, can be washed into the drainage ditch by rainwater during rain, eventually reaching the drainage outlet. When there is a large amount of debris, it can clog the drainage pipes and affect drainage efficiency. This application provides a drainage structure adapted to large-section gutters.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A drainage structure adapted to large cross-section gutters includes a drainage ditch, two symmetrically arranged mounting strips fixed to the side of the drainage ditch, mounting holes provided on the mounting strips, a drainage pipe fixed to the lower end of the drainage ditch, the drainage pipe communicating with the drainage ditch, and a filter structure provided inside the drainage ditch.
[0008] By adopting the above technical solution, when it rains, rainwater flows down the greenhouse into the drainage ditch, then through the drainage ditch into the drainage pipe, and finally out. The filtration structure can filter the rainwater, reducing the risk of clogging the drainage pipe.
[0009] Furthermore, the filter structure includes a barrier plate installed inside the drainage ditch, the barrier plate having a plurality of water-permeable holes, a handle fixed to the barrier plate, and a fixing component provided between the barrier plate and the drainage ditch.
[0010] By adopting the above technical solution, the barrier plate can block larger debris and reduce the amount of debris entering the drain pipe.
[0011] Furthermore, a filter plate is fixed to the lower end of the barrier sheet, and the holes in the filter plate are smaller than the water-permeable holes.
[0012] By adopting the above technical solution, the filter plate can filter out smaller debris, further reducing the amount of debris entering the drain pipe.
[0013] Furthermore, the fixing component includes an installation groove formed on the side of the drainage ditch, a fixing block is slidably disposed inside the installation groove, and a fixing hole adapted to the fixing block is formed on the side of the barrier plate.
[0014] By adopting the above technical solution, the filter plate can be quickly disassembled and installed using the fixing components, which facilitates the cleaning of the filter plate.
[0015] Furthermore, a fixing spring is fixed inside the mounting groove, and the fixing spring is fixedly connected to the fixing block.
[0016] By adopting the above technical solution, the fixing spring plays the role of supporting the fixing block, so that the fixing block can fix the barrier plate.
[0017] Furthermore, a filter pipe is threadedly connected inside the drain pipe, and a filter screen is fixed inside the filter pipe. The mesh size of the filter screen is smaller than the holes of the filter plate.
[0018] By adopting the above technical solution, rainwater can be further filtered using a filter screen, further reducing clogging.
[0019] Furthermore, a guide plate is fixed at the bottom of the drainage ditch, and the guide plate is inclined.
[0020] By adopting the above technical solution, the guide plate can be used to allow rainwater inside the drainage ditch to quickly enter the drainage pipe, thereby improving drainage efficiency.
[0021] Furthermore, several buffer plates are fixed inside the drain pipe, and the buffer plates are inclined.
[0022] By adopting the above technical solution, the buffer plate can buffer rainwater, thereby reducing splashing when rainwater is discharged.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. When using this drainage structure, rainwater first passes through the baffle plate as it falls into the drainage ditch. The baffle plate separates larger pieces of debris. The rainwater then falls through the permeable holes and then through the filter plate, which further filters the rainwater before it falls into the drainage ditch. When the rainwater enters the drainage pipe, it first passes through the filter pipe and is further filtered by the filter screen. Through multiple filtrations of the rainwater, the entry of debris is reduced, thus reducing the likelihood of blockages in the drainage pipe.
[0025] 2. The fixing components enable quick disassembly and installation of the barrier plates and filter plates, which facilitates cleaning of the filter plates and improves convenience. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.
[0033] This application discloses a drainage structure adapted to large-section gutters.
[0034] Reference Figure 1 and Figure 2 A drainage structure adapted to large cross-section gutters includes a drainage ditch 1 with a widened design. Two symmetrically arranged mounting strips 2 are fixed on the side of the drainage ditch 1, and mounting holes 3 are opened on the mounting strips 2. A drainage pipe 4 is fixed at the lower end of the drainage ditch 1, and the drainage pipe 4 is connected to the drainage ditch 1. A filter structure is provided inside the drainage ditch 1.
[0035] When using this drainage structure, the drainage ditch 1 is placed on the top of the greenhouse and fixed with bolts through the mounting holes 3. When it rains, the rainwater will fall into the drainage ditch 1 along the greenhouse, and then enter the drainage pipe 4 through the drainage ditch 1 and be discharged through the drainage pipe 4. When the rainwater enters the drainage ditch 1, the filter structure can filter the rainwater and reduce the blockage of the drainage pipe 4 caused by debris.
[0036] Reference Figure 2 and Figure 3 The filter structure includes a barrier plate 5 installed inside the drainage ditch 1. The barrier plate 5 has several water-permeable holes 6. A handle 7 is fixed on the barrier plate 5. A fixing component is provided between the barrier plate 5 and the drainage ditch 1.
[0037] Among them, the lower end of the barrier plate 5 is fixed with a filter plate 8, and the holes of the filter plate 8 are smaller than the water permeable holes 6.
[0038] In addition, the fixing component includes a mounting groove 9 opened on the side of the drainage ditch 1, a fixing block 10 is slidably disposed inside the mounting groove 9, and a fixing hole 12 adapted to the fixing block 10 is opened on the side of the barrier plate 5.
[0039] Furthermore, a fixing spring 11 is fixed inside the mounting groove 9, and the fixing spring 11 is fixedly connected to the fixing block 10.
[0040] When using this drainage structure, rainwater first passes through the barrier plate 5 when it falls into the drainage ditch 1. The barrier plate 5 isolates larger debris. The rainwater then falls through the permeable holes 6 and then through the filter plate 8. The filter plate 8 further filters the rainwater before it finally falls into the drainage ditch 1. By filtering the rainwater multiple times, the amount of debris in the rainwater can be reduced, thereby reducing the blockage of the drainage pipe 4 and reducing the impact of debris on drainage efficiency. When there is a lot of debris on the barrier plate 5 and inside the filter plate 8 that needs to be cleaned, first clean the debris off the barrier plate 5. Then pull the handle 7 upwards to apply force to the barrier plate 5. The force on the barrier plate 5 will apply force to the fixing block 10, causing the fixing block 10 to retract into the mounting groove 9 and compress the fixing spring 11, thus separating the fixing block 10 from the fixing hole 12. This separates the barrier plate 5, along with the filter plate 8, from the drain ditch 1, allowing for cleaning. After cleaning, align the barrier plate 5 with the drain ditch 1 and press the barrier plate 5 downwards to apply force to the fixing block 10, causing it to retract into the mounting groove 9. Once the fixing block 10 is aligned with the fixing hole 12, it will no longer be under force and will return to its original position under the action of the fixing spring 11, entering the fixing hole 12. This completes the installation of the barrier plate 5 and the filter plate 8. The fixing assembly allows for quick disassembly and installation of the barrier plate 5 and the filter plate 8, facilitating cleaning of the filter plate 8 and improving convenience.
[0041] Reference Figure 2 and Figure 4 The drain pipe 4 is internally threaded with a filter pipe 13, and a filter screen 14 is fixed inside the filter pipe 13. The mesh size of the filter screen 14 is smaller than the holes of the filter plate 8.
[0042] When rainwater enters the drain pipe 4, it first passes through the filter pipe 13 and then through the filter screen 14 to further filter the rainwater, reducing the entry of debris and reducing blockage.
[0043] A guide plate 15 is fixed at the bottom of the drainage ditch 1, and the guide plate 15 is inclined.
[0044] The diversion pipe allows rainwater entering the drainage ditch 1 to enter the drainage pipe 4 more quickly, increasing the drainage speed and reducing rainwater accumulation.
[0045] Reference Figure 2 Several buffer plates 16 are fixed inside the drain pipe 4, and the buffer plates 16 are inclined.
[0046] After rainwater enters the drain pipe 4, it will fall onto several buffer plates 16 in sequence. The buffer plates 16 can buffer the rainwater to a certain extent, thereby reducing the impact force when the rainwater falls and reducing the splashing of rainwater.
[0047] Working principle: When using this drainage structure, the drainage ditch 1 is placed on the top of the greenhouse and fixed with bolts through the mounting holes 3. When it rains, when the rainwater falls into the drainage ditch 1, it first passes through the baffle plate 5, which isolates larger debris. The rainwater then falls through the permeable holes 6 and then through the filter plate 8, which further filters the rainwater before it falls into the drainage ditch 1. When the rainwater enters the drainage pipe 4, it first passes through the filter pipe 13, where the filter screen 14 further filters the rainwater, reducing the entry of debris. The guide pipe allows the rainwater entering the drainage ditch 1 to enter the drainage pipe 4 more quickly and finally be discharged through the drainage pipe 4.
[0048] When there is a lot of debris on the barrier plate 5 and inside the filter plate 8 that needs to be cleaned, first clean the debris off the barrier plate 5, then pull the handle 7 upwards to apply force to the barrier plate 5. The force on the barrier plate 5 will apply force to the fixing block 10, which will retract into the mounting groove 9 and squeeze the fixing spring 11, causing the fixing block 10 to separate from the fixing hole 12. This will separate the barrier plate 5 and the filter plate 8 from the drain ditch 1, after which cleaning can be carried out. After cleaning, align the barrier plate 5 with the drain ditch 1 and press the barrier plate 5 downwards to apply force to the fixing block 10, causing it to retract into the mounting groove 9. When the fixing block 10 is aligned with the fixing hole 12, the fixing block 10 will no longer be under force. At this time, the fixing block 10 will return to its original position under the action of the fixing spring 11 and enter the fixing hole 12, thus realizing the installation of the barrier plate 5 and the filter plate 8.
