Description

Technical Field

[0001] This utility model relates to the field of ecological buoy technology, specifically to an ecological buoy natural ventilation device. Background Technology

[0002] Aquatic ecological restoration has become a key focus in environmental protection in recent years, especially as urbanization has exacerbated water pollution, placing significant pressure on aquatic ecosystems. To address this, researchers have proposed a series of ecological restoration technologies, including bioremediation, physical remediation, and chemical remediation. Among these, using ecological floating spheres to plant vegetation has become a popular restoration method because it can both remove pollutants from water bodies and improve their ecological environment.

[0003] A search revealed an existing technology (Publication No.: CN118108339A) that discloses an integrated wind and wave-resistant ecological buoy for water ecological restoration. The document describes that "the air supply assembly includes an air supply cylinder, a piston, a delivery pipe, a float, and a third return spring; the air supply cylinder is fixedly installed on the base plate by a seventh bolt; the piston is sealed and assembled inside the air supply cylinder; the float is arranged below the base plate and is fixedly connected to the piston by a support rod; a limit seat is fixed at the bottom of the support rod, and the third return spring is formed around the support rod, with both ends of the third return spring abutting against the base plate and the limit seat respectively; one end of the delivery pipe connects to the top of the air supply cylinder, and the other end is arranged at the clearance opening; an air supply passage is opened in the side wall of the air supply cylinder, which connects the external environment to the inner cavity of the air supply cylinder; the delivery pipe..." The supply pipe is equipped with a first one-way valve, and the air supply passage is equipped with a second one-way valve. The ecological float is equipped with an air supply component, which operates in response to the changes in water waves to draw in air from the environment and deliver it to the bottom of the planting cylinder, ensuring that the ecological plants can still grow normally in environments with large waves. However, the second one-way valve in the air supply component does not have any protective structure on its outside. Therefore, when outside air flows into the air supply cylinder through the second one-way valve, the liquid stirred up by the outside waves can also easily pass through the second one-way valve along with the airflow. With the long-term use of the ecological float, a large amount of liquid can easily accumulate inside the air supply cylinder, which will interfere with the normal operation of the air supply component. At the same time, the air supply component only exchanges gas through one set of second one-way valves, and the air inlet of the vertically set second one-way valve is easily covered and blocked by aquatic plants and other external debris, making the entire air supply component prone to failure and unusable. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, an ecological floating ball natural ventilation device is provided to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, an ecological float natural ventilation device is provided, comprising: an air supply cylinder and a fixing plate. A delivery pipe is fixedly connected to the upper surface of the air supply cylinder, and a piston slidably connected inside the air supply cylinder is fixedly connected to the float body via a support rod. A return spring is sleeved on the surface of the support rod.

One end of a guide pipe is symmetrically connected to the bottom of the inner side of the air supply cylinder, and the other end of the guide pipe is fixedly connected to the outer side of the air supply cylinder via a positioning block. A fixing plate is fixedly connected to the upper end of the outer side of the air supply cylinder. A manifold is opened on the inner side of the fixing plate corresponding to the position of the one-way valve, and a through groove is symmetrically opened on the surface of the fixing plate. The two ends of the through groove are connected to the corresponding manifold through a guide groove.

[0006] Preferably, the air supply cylinder has a cylindrical structure, and four sets of mounting slots are equally spaced around the inner cavity of the air supply cylinder. All four sets of mounting slots are cylindrical, and the inner cavity of the mounting slots is connected to the outer side of the air supply cylinder through a one-way valve.

[0007] Preferably, the fixing plate has a circular structure, the inner diameter of the fixing plate is equal to the outer diameter of the air supply cylinder, and four sets of manifolds are opened on the inner side of the fixing plate relative to the position of the one-way valve. At the same time, the four sets of manifolds are all cuboid structures, and the four sets of manifolds are all connected to the inner side of the fixing plate.

[0008] Preferably, the surface of the fixing plate has four sets of through slots at equal intervals around the circumference, and the four sets of through slots are all fan-shaped annular structures, while the through slots connect the upper and lower surfaces of the fixing plate.

[0009] Preferably, the through groove and the confluence groove are staggered, and the guide grooves opened at both ends of the through groove are all fan-shaped annular structures, while the end of the guide groove near the through groove is inclined downwards, and the size of the opening of the guide groove is smaller than the size of the end face of the through groove.

[0010] Preferably, multiple sets of air guide pipes are fixedly connected at equal intervals around the lower end of the outer side of the air supply cylinder, and the air guide pipes have an S-shaped structure. The air inlet of the air guide pipe at the end away from the air supply cylinder is vertically downward, and multiple sets of through holes are evenly opened on the side of the air guide pipe near the air inlet.

The sealing ring fixedly connected in the through hole has a circular structure, and the inner cavity of the sealing ring is compatible with the size of the support rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of the fixing plate, the manifold, the guide groove and the through groove, the outer side of the one-way valve can have a good protective structure. Under the premise of ensuring normal airflow, it can effectively prevent external liquids or debris such as water plants from approaching the one-way valve. It can prevent external liquids from accumulating in the air supply cylinder and interfering with the piston movement, and it can also prevent the air inlet of the one-way valve from being covered and blocked by debris. This ensures that the self-heating ventilation device can carry out normal gas exchange and improves the stability of the device. Attached Figure Description

[0018] Reference Figures 1 to 4 As shown, this utility model provides an ecological float natural ventilation device, including: an air supply cylinder 2 and a fixing plate 4. A delivery pipe 1 is fixedly connected to the upper surface of the air supply cylinder 2, and a piston 5 slidably connected inside the air supply cylinder 2 is fixedly connected to the float body 9 through a support rod 7. At the same time, a return spring 8 is sleeved on the surface of the support rod 7. The upper end of the inner side of the air supply cylinder 2 is symmetrically provided with mounting grooves 10, and a one-way valve 3 is fixedly connected in the mounting grooves 10. One end of the air guide pipe 14 is symmetrically connected to the bottom of the inner side of the air supply cylinder 2. The other end of the air guide pipe 14 is fixedly connected to the outer side of the air supply cylinder 2 through a positioning block. At the same time, the upper end of the outer side of the air supply cylinder 2 is fixedly connected with the fixing plate 4. A confluence groove 11 is provided on the inner side of the fixing plate 4 corresponding to the position of the one-way valve 3. A through groove 13 is symmetrically provided on the surface of the fixing plate 4. At the same time, the two ends of the through groove 13 are connected to the corresponding confluence groove 11 through the guide groove 12.

[0019] In this embodiment, the natural ventilation device operates under the influence of water wave fluctuations, drawing in air from the outside environment and delivering it through the delivery pipe 1 to the vicinity of the plant roots in the ecological float, ensuring normal plant growth. When the float pushes the piston 5 upward via the support rod 7, the piston 5 injects the gas above into the delivery pipe 1. As the piston 5 moves upward, outside gas flows into the area below the piston 5 through the air guide pipe 14, effectively reducing the difficulty of moving the piston 5. After the piston 5 resets in the air supply cylinder 2, the space above the piston 5 expands, allowing outside airflow to first flow into the through groove 13, then along the guide grooves 12 at both ends of the through groove 13 into the confluence groove 11. Subsequently, outside airflow can smoothly flow into the air supply cylinder 2 through the one-way valve 3, ensuring that the piston 5 can reset smoothly. The gas below the piston 5 is then discharged from the air guide pipe 14, thus enabling the natural ventilation device to operate normally.

[0020] Meanwhile, the connection structure between the ecological buoy and the air supply cylinder 2, the principle of water waves pushing the piston 5 inside the air supply cylinder 2 through the buoy and the automatic reset of the piston 5 are all existing mature technologies, which have been fully disclosed in (Announcement No.: CN118108339A) an integrated wind and wave resistant ecological buoy for water ecological restoration.

[0021] In a preferred embodiment, the air supply cylinder 2 has a cylindrical structure, and four sets of mounting grooves 10 are equally spaced around the inner cavity of the air supply cylinder 2. All four sets of mounting grooves 10 have a cylindrical structure, and the inner cavity of the mounting grooves 10 is connected to the outer side of the air supply cylinder 2 through a one-way valve 3.

[0022] In this embodiment, as Figure 1 and Figure 2 The opening of four sets of mounting slots 10 enables the air supply cylinder 2 to have multiple airflow exchange points. Therefore, even if a one-way valve 3 is damaged and cannot be used, the air supply cylinder 2 can still carry out normal airflow exchange, thereby effectively enhancing the durability of the natural ventilation device.

[0023] In a preferred embodiment, the fixing plate 4 has a circular structure, the inner diameter of the fixing plate 4 is equal to the outer diameter of the air supply cylinder 2, and four sets of manifolds 11 are opened on the inner side of the fixing plate 4 relative to the position of the one-way valve 3. At the same time, the four sets of manifolds 11 are all cuboid structures, and the four sets of manifolds 11 are all connected to the inner side of the fixing plate 4.

[0024] In this embodiment, as Figure 1 and Figure 2 The manifold 11 is formed in the fixing plate 4, which can not only prevent the one-way valve 3 from interfering with the installation of the fixing plate 4, but also help improve the airflow extraction effect of the one-way valve 3, so that the one-way valve 3 can be in a relatively closed environment, reducing the chance of the one-way valve 3 being blocked.

[0025] In a preferred embodiment, four sets of through slots 13 are equally spaced around the surface of the fixing plate 4, and the four sets of through slots 13 are all fan-shaped annular structures. At the same time, the through slots 13 connect the upper and lower surfaces of the fixing plate 4.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The opening of the through groove 13 allows the external airflow to flow smoothly to the one-way valve 3, while also filtering the splashed liquid from the outside. This prevents the liquid from stagnating and accumulating in the through groove 13, thus effectively reducing the probability of liquid and external debris approaching the one-way valve 3. It also effectively prevents the through groove 13 from being completely blocked.

[0027] In a preferred embodiment, the through groove 13 and the confluence groove 11 are staggered, and the guide grooves 12 opened at both ends of the through groove 13 are all fan-shaped annular structures. The end of the guide groove 12 near the through groove 13 is inclined downward, and the size of the opening of the guide groove 12 is smaller than the size of the end face of the through groove 13.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The inclined structure of the guide channel 12 can effectively block the inflow of external debris and quickly discharge any accidentally entered liquid or debris, thereby ensuring the stability of the one-way valve 3.

[0029] In a preferred embodiment, multiple sets of air guide pipes 14 are fixedly connected around the lower end of the outer side of the air supply cylinder 2 at equal intervals. The air guide pipes 14 have an S-shaped structure, and the air inlet of the air guide pipe 14 at the end away from the air supply cylinder 2 is vertically downward. At the same time, multiple sets of through holes are evenly opened on the side of the air guide pipe 14 near the air inlet.

[0030] In this embodiment, as Figure 1 The arrangement of the air guide pipe 14 allows the cavity below the piston 5, which gradually expands as the piston 5 moves upward, to be quickly replenished with the corresponding gas. This ensures that the air pressure inside the air supply cylinder 2 is in a balanced state, which in turn facilitates the up-and-down movement of the piston 5. At the same time, the structure and number of air guide pipes 14 can reduce the chance of the air guide pipes 14 being blocked and prevent external liquid from flowing into the air supply cylinder 2 through the air guide pipes 14, thus ensuring the overall stability of the natural ventilation device.

[0031] In a preferred embodiment, the support rod 7 has a cylindrical structure and is slidably connected to a through hole at the bottom of the air supply cylinder 2. The sealing ring 6 fixedly connected in the through hole has a circular structure, and the inner cavity of the sealing ring 6 is adapted to the size of the support rod 7.

[0032] In this embodiment, as Figure 1 and Figure 2 The sealing ring 6 is made of soft rubber, which can effectively enhance the sealing of the connection between the bottom of the air supply cylinder 2 and the support rod 7, so that the natural ventilation device can provide appropriate ventilation for the ecological float.

[0033] The ecological float natural ventilation device of this utility model, through the cooperation of the fixed plate 4, the through groove 13, the guide groove 12 and the confluence groove 11, enables the airflow to flow stably through the one-way valve 3, preventing external liquid from flowing into the air supply cylinder 2 along with the airflow, and also preventing the one-way valve 3 from being blocked by external debris, thus improving the stability of the natural ventilation device during use. Moreover, through the cooperation of the air guide pipe 14, the difficulty of moving the piston 5 can also be reduced.
