Description

Technical Field

[0001] This application relates to the technical field of garden drainage, and in particular to garden odor-proof drainage channels. Background Technology

[0002] Drainage channels are commonly installed in outdoor landscape areas such as gardens, courtyards, and plazas. Their main function is to quickly collect and drain surface rainwater, irrigation wastewater, and wastewater from site washing. These drainage channels are connected to underground rainwater pipe networks or regional sewer pools and collection wells through drainage outlets at their bottoms, forming a basic site drainage system.

[0003] However, the drainage pools connected to the drainage channels accumulate rainwater, silt, and decaying matter over time, which ferments and produces large amounts of odorous gases and harmful bacteria. The existing drainage channels lack a continuous and effective sealing mechanism, allowing these odorous gases to escape back into the ground environment through the drain outlets. This not only seriously pollutes the air in the park area but also poses a potential threat to the surrounding environmental hygiene. Utility Model Content

[0004] In view of the shortcomings of the existing technology, one of the purposes of this utility model is to provide a garden odor-proof drainage ditch.

[0005] The garden odor-proof drainage ditch provided in this application adopts the following technical solution:

[0006] The garden odor-proof drainage ditch includes a ditch body, a vertical drainage pipe is provided at the lower end of the ditch body, a drainage outlet is provided below the drainage pipe, a rotating shaft is provided at the drainage outlet, and a cover plate for opening and closing the drainage outlet is rotatably connected to the rotating shaft.

[0007] A permanent magnet is installed at the drain outlet, and the cover plate is made of magnetic stainless steel.

[0008] The permanent magnet is coupled to the cover plate via a magnetic field;

[0009] The cover plate is also connected to a gravity reset mechanism that uses gravity to achieve the reclosing of the cover plate;

[0010] The gravity reset mechanism has a counterweight, and the counterweight and the cover plate are located on opposite sides of the rotating shaft, respectively.

[0011] The cover plate and the counterweight form a lever structure with the pivot as the fulcrum, and the gravitational torque of the counterweight is greater than that of the cover plate.

[0012] The length of the drainage pipe is 15-20 cm;

[0013] The magnetic force between the permanent magnet and the cover plate is set to be greater than the pressure of a 15 cm high water column in the drainage pipe and less than the pressure of a 20 cm high water column.

[0014] By adopting the above technical solution, the cover plate and counterweight are designed on both sides of the rotating shaft, forming a lever structure with the rotating shaft as the fulcrum. At the same time, combined with the magnetic field coupling effect generated by the permanent magnet on the magnetic stainless steel cover plate, the magnetic force of the permanent magnet and the gravity of the counterweight produce a synergistic effect, jointly providing a continuous closing force for the cover plate, ensuring that the drain outlet is closed in the absence of water. During drainage, increased sewage pressure pushes the cover open to drain water. As the drainage volume decreases, the counterweight, under its own weight, gradually rotates the cover back to close. Once within the effective range of the permanent magnet, the magnetic force between the permanent magnet and the cover, along with the counterweight, completely closes the drain outlet, forming a highly efficient odor-proof barrier and automating drainage. By setting the magnetic force between the permanent magnet and the cover to be greater than 15 cm of water column pressure but less than 20 cm, sufficient impact force is generated to open the cover when at least 15 cm of water has accumulated, facilitating waste discharge and sewer cleaning. This also effectively avoids frequent opening and closing of the cover due to small water volumes, maximizing the odor-proof effect and protecting moving parts. Furthermore, the magnetic force is essentially ineffective after the cover is opened, ensuring continuous drainage even with small water flows, guaranteeing excellent drainage performance.

[0015] Preferably, a filter plate is provided on the top of the tank.

[0016] By adopting the above technical solution, large debris such as leaves and plastic bags are physically intercepted, effectively preventing these foreign objects from entering the tank and impacting the lever mechanism with the water flow, or from getting stuck between the cover plate and the drain outlet. This avoids problems such as the cover plate not closing tightly, magnetic attraction failure, and stuck reset action caused by external force interference.

[0017] Preferably, the outer surface of the permanent magnet is covered with an anti-corrosion coating.

[0018] By adopting the above technical solution, an anti-corrosion coating is applied to the outer surface of the permanent magnet, which can effectively isolate the permanent magnet from direct contact with humid air and corrosive substances in sewage. This prevents the permanent magnet from losing its magnetic properties or structural damage due to oxidation and corrosion, ensuring the long-term stability of the magnetic attraction force and avoiding the impact of the cover's closing effect due to weakened magnetic force. In essence, this ensures the service life of the drainage trough's odor-proof function.

[0019] Preferably, the gravitational torque of the counterweight is 1.5 to 2.5 times that of the gravitational torque of the cover plate.

[0020] By adopting the above technical solution, the gravitational torque of the counterweight is limited to 1.5-2.5 times the gravitational torque of the cover plate, achieving the optimal configuration of mechanical balance. This ratio range ensures the closing efficiency of the cover plate, avoids incomplete closing due to insufficient torque, and prevents the cover plate from frequently opening and closing when the water flow is small due to excessive torque, thereby reducing the impact on the drainage pipe and extending the service life of the equipment.

[0021] Preferably, a rubber pad for cushioning is provided on the surface of the cover plate that contacts the drain outlet.

[0022] By adopting the above technical solution, a rubber pad is placed on the contact surface between the cover plate and the drain outlet, which can effectively absorb the impact energy of the collision at the moment the cover plate closes, significantly reducing noise and reducing structural wear on components such as the cover plate and permanent magnet. At the same time, the elastic deformation of the rubber pad also helps to enhance the tightness of the sealing interface, forming a beneficial secondary sealing effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The cover plate and counterweight are designed on both sides of the pivot, forming a lever structure with the pivot as the fulcrum. Simultaneously, the magnetic field coupling effect of the permanent magnet on the magnetic stainless steel cover plate creates a synergistic effect between the magnetic force of the permanent magnet and the gravity of the counterweight, providing a continuous closing force for the cover plate and ensuring the drain outlet is closed even when there is no water. During drainage, when the sewage pressure increases, it pushes the cover plate to open and drain. As the drainage volume decreases, the counterweight, relying on its gravity, drives the cover plate to gradually rotate and close. Once within the effective range of the permanent magnet, the magnetic force between the permanent magnet and the cover plate, together with the counterweight, completes the full closure of the drain outlet, forming a highly efficient odor-proof barrier and achieving automated drainage. Furthermore, by setting the magnetic force between the permanent magnet and the cover plate to be greater than 15 cm of water column pressure but less than 20 cm of water column pressure, it ensures that a minimum of 15 cm of water column is accumulated to generate sufficient impact force to open the cover plate, facilitating the discharge of waste and cleaning of the sewer. It also effectively avoids frequent opening and closing of the cover plate due to small water flows, maximizing the odor-proof effect and protecting moving parts. In addition, the magnetic force is essentially ineffective after the cover plate is opened, ensuring continuous drainage even with small water flows, guaranteeing excellent drainage performance.

[0025] 2. By physically intercepting large debris such as leaves and plastic bags, it effectively prevents these foreign objects from entering the tank and impacting the lever mechanism with the water flow, or from getting stuck between the cover plate and the precision sealing surface of the drain outlet. This avoids problems such as the cover plate not closing tightly, magnetic attraction failure, and stuck reset action caused by external force interference.

[0026] 3. By limiting the gravitational torque of the counterweight to 1.5-2.5 times that of the cover plate, the optimal configuration of mechanical balance is achieved. This ratio range ensures the efficiency of the cover plate closing, avoids incomplete closing due to insufficient torque, and prevents the cover plate from frequently opening and closing when the water flow is small due to excessive torque, thereby reducing the impact on the drainage pipe and extending the service life of the equipment.

[0029] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0030] This application discloses a garden odor-proof drainage ditch.

[0031] Reference Figure 1 The garden odor-proof drainage ditch includes a ditch body 1, which is typically buried in the garden ground to collect surface rainwater, water used for watering greenery, and wastewater from site washing. A filter plate 8 is installed at the top of the ditch body 1, which physically intercepts large debris such as leaves and plastic bags, effectively preventing these foreign objects from entering the ditch body 1. A vertical drainage pipe 2 is connected to the lower end of the ditch body 1, and a drain outlet 3 is located at the bottom of the drainage pipe 2. A rotating shaft 4 is installed at the drain outlet 3, and a cover plate 5 for opening and closing the drain outlet 3 is rotatably connected to the rotating shaft 4.

[0032] To ensure stable closure of the cover 5 and prevent odor escape, a permanent magnet 6 is installed at the drain outlet 3. Specifically, the permanent magnet 6 is located on the side of the drain outlet 3 opposite to the rotating shaft 4. The cover 5 is made of magnetic stainless steel, allowing the permanent magnet 6 and the cover 5 to generate a strong adsorption coupling through the magnetic field.

[0033] The cover plate 5 is also connected to a gravity reset mechanism that uses gravity to reclose the cover plate 5. The gravity reset mechanism has a counterweight 7, which is located on both sides of the rotating shaft 4, thus forming a lever structure with the rotating shaft 4 as the fulcrum. Furthermore, the gravitational torque of the counterweight 7 is greater than that of the cover plate 5. This lever structure allows the gravity of the counterweight 7 and the magnetic attraction of the permanent magnet 6 to act together on the cover plate 5, producing a synergistic effect that drives the cover plate 5 to close the drain outlet 3 in a waterless state.

[0034] To facilitate the discharge of wastewater from tank 1, the length of drainage pipe 2 is 15-20 cm. The magnetic strength between permanent magnet 6 and cover plate 5 is set to be greater than the pressure of a 15 cm high water column in drainage pipe 2, but less than the pressure of a 20 cm high water column. The length of drainage pipe 2, designed to be 15-20 cm, ensures that a sufficient height of water column accumulates within tank 1, generating the necessary hydrostatic pressure to overcome the combined resistance formed by the magnetic attraction of permanent magnet 6 and the gravity of counterweight 7. This allows cover plate 5 to open for drainage, accumulating at least a 15 cm water column. When cover plate 5 opens, a high water flow is instantaneously generated, facilitating the discharge of wastewater and impact cleaning of the sewer below. It also avoids frequent opening of cover plate 5 due to small water volumes, thus maximizing odor prevention and protecting moving parts. After cover plate 5 is opened, the magnetic force is essentially ineffective; even with a small water flow, cover plate 5 will not return to its original position, allowing for continuous small-volume drainage and ensuring good drainage performance. While drainage pipe 2 is over 20 cm long, it can ensure automatic sewage discharge, but it requires a large installation space in the garden site, which greatly reduces the flexibility of drainage trough layout. In this embodiment, the length of drainage pipe 2 is 15 cm. This length of drainage pipe 2 can ensure that a water column of about 15 cm high is formed in the trough 1. The hydrostatic pressure generated is just higher than the combined resistance formed by the magnetic attraction of permanent magnet 6 and the gravity of counterweight 7, which is enough to open the cover plate 5 for drainage. Moreover, the 15 cm length is the most compact, minimizing the occupation of underground space.

[0035] To further enhance the product's durability, the outer surface of the permanent magnet 6 is covered with an anti-corrosion coating, which effectively prevents the permanent magnet 6 from corroding in humid environments, ensuring the long-term stability of the permanent magnet 6's magnetic force, thereby ensuring the long-lasting effectiveness of the drainage channel's odor-proof function.

[0036] Preferably, the gravitational torque of the counterweight 7 is 1.5 to 2.5 times that of the gravitational torque of the cover plate 5, ensuring that a small counterweight can generate sufficient torque, which ensures that the cover plate 5 can stably close the drain outlet 3 and can sensitively reset the cover plate 5 after drainage. At the same time, it prevents the cover plate 5 from frequently opening and closing when the water flow is small due to excessive torque, thus reducing the impact on the drainage pipe 2. In this embodiment, the gravitational torque of the counterweight 7 is twice that of the cover plate 5. After drainage, the gravity of the counterweight 7 can quickly and directly drive the lever to rotate and re-close the drain outlet 3.

[0037] In addition, a rubber pad 9 is provided on the contact surface between the cover plate 5 and the drain outlet 3. The rubber pad 9 can effectively absorb the impact energy of the collision when the cover plate 5 is closed. At the same time, the rubber pad 9 and the magnetic attraction of the permanent magnet together form an odor-proof sealing barrier.

[0038] The implementation principle of this application embodiment is as follows:

[0039] In the absence of drainage, the magnetic attraction of the permanent magnet 6 and the gravity of the counterweight 7 work together through the lever structure to drive the cover 5 tightly against the drain outlet 3, forming a reliable seal and effectively preventing odor from escaping. When sewage flows into the tank 1 and reaches a certain water level, the impact force generated by the water pressure overcomes the magnetic attraction and the gravity of the counterweight 7, pushing the cover 5 to rotate around the pivot 4 and open, initiating drainage. After drainage is completed, the water pressure decreases, and the gravitational torque of the counterweight 7 drives the lever to rotate, causing the cover 5 to gradually close. When it enters the effective range of the permanent magnet 6, the magnetic attraction quickly pulls the cover 5 to a fully closed position, restoring the odor-proof state.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
