Description

Technical Field

[0001] This utility model belongs to the field of water surface floating object blocking technology, specifically relating to a water floating object blocking device. Background Technology

[0002] To prevent the continuous spread of floating debris, many bodies of water, especially small and medium-sized bodies where the surface is easily controlled, employ measures to intercept floating debris. This measure involves deploying obstruction devices on the water surface to block the debris and prevent it from flowing downstream. Currently, there are two common types of floating debris interception devices. One type is a fixed interception device, consisting of ropes and buoys. The ropes connecting the buoys are fixed at both ends to the sides of the water surface, and the buoys intercept the floating debris. This type of device can only intercept floating debris on the water surface. The floating debris easily overflows after accumulating and then floats past the buoys. Moreover, this type of device is only suitable for water bodies with small fluctuations in water level, and its adaptability is somewhat insufficient. Another type is the liftable barrier device. These devices typically include a mechanical structure that allows the barrier components to move up and down, adjusting their position according to water level fluctuations via self-powered or externally input power. While these devices offer some adaptability, their structure is relatively complex. Due to high humidity, the metal parts are prone to rust and jamming over time, requiring frequent maintenance, which is labor-intensive and time-consuming. Furthermore, these devices often suffer from the problem of floating debris accumulating and continuing to drift downstream. Therefore, it is necessary to develop a floating debris barrier device that possesses both better blocking capabilities and the ability to adjust its position according to water level fluctuations. Utility Model Content

[0003] The purpose of this invention is to provide a device for blocking floating objects in water. This device uses a net to intercept floating objects and includes a float. The device can adjust the position of the net by adjusting the float, so that it can still play a blocking role in water bodies with large fluctuations in water level.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A floating object blocking device includes two installation units, a suspension member, and a blocking net. Each installation unit includes a support and a buoy. The supports in the two installation units are erected on both sides of the water area to be blocked. Both buoys can move up and down relative to the supports. A fixing member is fixedly installed at the upper end of each buoy. Both the support and the buoy are partially submerged in water. The suspension member is strip-shaped, with its two ends fixedly connected to the two fixing members. The upper edge of the blocking net is fixedly installed on the suspension member, and a counterweight is fixedly installed on the lower edge. The length of its upper edge is equal to the overall length of the suspension member.

[0006] In existing technologies, most floating object blocking devices can only intercept floating objects on the water surface, and the device's position is fixed. Some devices can be adjusted in position, but their structure is complex and maintenance costs are high. In this invention, the part used to intercept floating objects is a blocking net. This net is perpendicular to the water plane, with part above the water surface and part submerged. The width of the net is equal to the width of the water body to be intercepted, effectively preventing floating objects from accumulating and overflowing. The blocking net is suspended from a suspension member, whose two ends are connected to the installation unit. This ensures that the position of the blocking net remains relatively fixed to the water surface within a certain range, guaranteeing the device's consistently high blocking capacity. The upper end of the blocking net is mounted on the suspension member, and the lower end is equipped with a counterweight. This structure allows the installation unit to withstand less force, which helps extend the device's service life. Thus, regardless of whether the blocking net is rigid or flexible, the counterweight at the lower end keeps the net nearly perpendicular to the water plane.

[0007] Further optimization involves creating vertically distributed receiving grooves within the support piers, with the pontoons installed within these grooves and unable to detach from them. A track is fixedly installed within the receiving grooves; the track is trough-shaped and distributed vertically as a whole. Sliding components are fixedly installed at the upper and lower ends of the pontoons, and these sliding components are slidably installed within the track.

[0008] The placement of the pontoon within the receiving tank effectively protects it from damage such as collisions, preventing loss of buoyancy and a decrease in the device's stopping power. It also prevents the pontoon from detaching from the support, thus avoiding malfunction. A sliding component is installed at each end of the pontoon, with a track within the receiving tank allowing the components to slide freely. This prevents direct contact and friction between the pontoon and the tank, avoiding damage and loss of buoyancy due to friction after prolonged use, and increasing the device's reliability.

[0009] In a further optimization, the sliding component achieves sliding in the track through a main roller and multiple secondary rollers. The central axis of the main roller is parallel to the width direction of the track, and the central axes of the main roller and the secondary rollers are perpendicular. During the up-and-down movement of the float, the main roller and the secondary rollers always remain in contact with the track.

[0010] Considering the wave-like characteristics of water surfaces in reality, the position of the pontoon will constantly rise and fall with the water's movement. During this rise and fall, the pontoon will be constantly subjected to horizontal forces, causing it to sway horizontally. Over time, this can easily lead to metal fatigue or other forms of failure in the device's components. The sliding assembly includes main rollers and secondary rollers that respectively abut against the bottom and sides of the track. This helps to maintain the relative position of the pontoon and the support as fixed as possible, preventing swaying. With multiple tracks and corresponding sliding assemblies, the device can achieve even better sway prevention.

[0011] Further optimization involves fixing the barrier net to the suspension components using multiple mounting components. The device also includes multiple protective covers, with all mounting components housed within the protective covers. The protective covers have perforations and gaps, through which the suspension components pass into the protective covers. The upper end of the barrier net passes through the gaps, is housed within the protective covers, and is simultaneously mounted on the suspension components.

[0012] To facilitate production and transportation, the barrier net and suspension components are often manufactured as two separate parts, then transported to the body of water to be intercepted and installed together using mounting components. Considering the potential for various forms of accidental damage in reality—for example, devices deployed near waterways might be collided with or scraped by surface vessels or other vehicles, or devices deployed in mountain streams might be struck by falling rocks, causing the mounting components to break and the barrier net to detach—protective covers are necessary to prevent damage and increase the reliability of the device. These covers also reduce the contact between the components and air, helping to slow down oxidation and extend the device's lifespan.

[0013] Further optimization: the protective cover is cylindrical in shape and consists of two parts. The two parts are symmetrical about the plane containing the central axis of the protective cover and are fixedly connected by bolts. The central axis of the perforation coincides with the central axis of the protective cover. The protective cover also has a mounting base for installing mounting components, which are fixedly installed on the protective cover by the mounting base.

[0014] The protective cover, composed of two symmetrical parts and fixed by bolts, is less likely to fall off the suspension component than a protective cover that is directly fitted onto the suspension component after being molded as a whole. The mounting component is fixed to the protective cover by the mounting base, so that the protective cover can always be fitted onto the mounting component and will not slip on the suspension component, causing the mounting component to be exposed from the protective cover. This ensures that the mounting component is always contained in the protective cover, thus providing a more complete protection for the mounting component.

[0015] Further optimization resulted in a buoy structure with an opening at its upper end.

[0016] Considering the need for flexible adjustment of the height of the protective netting relative to the water surface in practical applications, for example, when the floating debris is mostly styrofoam or similar floating objects, the upper edge of the netting needs to be higher above the water surface because the debris tends to accumulate above the surface. Conversely, when the floating debris is mostly dead leaves or similar submerged objects, the upper edge needs to be lower. The height of the netting relative to the water surface can be controlled by the weight of the pontoons. When the upper edge of the netting needs to be higher above the water surface, the pontoons need to be lighter, and vice versa. The pontoons have an open shell structure, allowing for the loading of heavy objects like stones, thus adjusting the overall weight of the pontoons. The opening at the top of the pontoons prevents turbulent water from entering.

[0017] The beneficial effects of this utility model device are as follows:

[0018] 1. The part of the device that intercepts floating objects is a barrier net, which can effectively prevent the intercepted floating objects from accumulating in front of the device and overflowing. It has a better interception effect than traditional barrier devices.

[0019] 2. The device has floats, and the position of the barrier net can be changed by the floats as the water level rises or falls, so that the barrier net maintains a fixed relative position with the water surface, which is more applicable than traditional barrier devices.

[0020] 3. The structure of the installation unit is that the float is installed in the receiving groove of the support, and the upper and lower ends of the float have sliding components. The receiving groove is equipped with a track for the sliding components to slide. The float will not detach from the support, nor will it sway relative to the support, thus reducing the possibility of device damage and giving the device a longer service life.

[0021] 4. The pontoons are open shell structures, and the positions of the upper and lower edges of the barrier net relative to the water surface can be adjusted by the weight of the weights loaded into the pontoons, thus making the device more flexible in use. Attached Figure Description

[0027] A floating object blocking device includes two installation units, a suspension member 4, and a blocking net 5. Each installation unit includes a support 1 and a float 2. The support 1 of the two installation units is erected on both sides of the water area to be blocked. The support 1 has a vertically distributed receiving groove. The float 2 is installed in the receiving groove and cannot be removed from the receiving groove. Two tracks 11 are fixedly installed in the receiving groove. The tracks 11 are groove-shaped and are distributed vertically. The positions of the two tracks 11 in the same receiving groove are as follows: Figure 3 As shown. Two sets of sliding components are fixedly installed at both the upper and lower ends of the pontoon 2. The two sets of sliding components at the same end are respectively slidably mounted on the two tracks 11. The pontoon 2 moves up and down in the receiving groove via these sliding components. Each sliding component includes a main roller 7 and two secondary rollers 8. During the up-and-down movement of the pontoon 2, the main roller 7 remains in contact with the bottom surface of the track 11, while the two secondary rollers 8 remain in contact with the two sides of the track 11 respectively. The overall external structure of the pontoon 2 is as follows. Figure 4 As shown, the pontoon 2 is installed in the receiving groove of the support 1 as follows: Figure 2 As shown.

[0028] Each pontoon 2 is fixedly equipped with a fixing member 10 at its upper end. In this embodiment, the fixing member 10 is as follows: Figure 4 The mooring stakes, pier 1, and buoy 2 shown are all partially submerged in water. The suspension member 4 is generally strip-shaped; in this embodiment, it is a steel wire rope, with both ends firmly attached to two fixing members 10. The extension direction of the suspension member 4 remains horizontal. The barrier net 5 in this embodiment is a flat wire mesh, generally rectangular. The upper edge of the barrier net 5 is fixed to the suspension member 4 by three mounting members 13; in this embodiment, the mounting members 13 are U-shaped pins. One mounting member 13 is housed within a protective cover 3. The protective cover 3 is generally cylindrical, composed of two parts symmetrical about the plane containing the central axis of the protective cover 3. The two parts of the protective cover 3 are fixedly connected by three bolts 12. The protective cover 3 has perforations and gaps. The suspension member 4 passes through the perforations into the protective cover 3, and the upper end of the barrier net 5 passes through the gaps and is housed within the protective cover 3 while simultaneously being mounted on the suspension member 4. The barrier net 5 is installed on the water body to be intercepted as shown in the image. Figure 1 As shown. Each protective cover 3 also has a mounting base 14 for installing the mounting component 13. The mounting component 13 is fixedly installed on the protective cover 3 through the mounting base 14, thereby fixing the relative positions of the protective cover 3, the suspension component 4, and the barrier net 5, as shown. Figure 5 As shown.

[0029] A counterweight 6 is fixedly installed on the lower edge of the barrier net 5. In this embodiment, the counterweight 6 consists of five small steel balls suspended from the lower edge of the barrier net 5 by ropes. The length of the upper edge of the barrier net 5 is equal to the overall length of the suspension component 4. The float 2 is a shell structure with an opening 9 at its upper end. Figure 2 As shown.

[0030] When deploying this utility model's barrier device, first erect supports 1 on both banks of the water body, then install floats 2 into the supports 1, and then tie the two ends of the suspension member 4 to the two fixing members 10 respectively. Then, use the mounting member 13 to fix the barrier net 5, the suspension member 4, and the part of the protective cover 3 with the mounting base 14 to the installation. Then, close the other part of the protective cover 3 and tighten the bolts to complete the installation. Before putting it into use, determine the distance between the upper and lower edges of the barrier net 5 and the water surface according to the local floating object distribution. Then, put a certain amount of stones into the floats 2 to position the barrier net 5 in the required position. During use, when the water level rises, the floats 2 will rise accordingly, causing the barrier net 5 to rise. When the water level falls, the floats 2 will fall accordingly, causing the barrier net 5 to fall.

[0031] It is understandable that the support 1 and the pontoon 2 can also be other forms of sliding devices, as long as the condition that the pontoon 2 can slide up and down relative to the support 1 is met.

[0032] Understandably, the suspension component 4 can also be a rope of other materials or a fixed-shape pole, as long as it can suspend a net. The barrier net 5 can also be a net of other materials or a flexible net.

[0033] It is understandable that the device may also be without track 11 and sliding components.

[0034] It is understandable that the device may not have mounting part 13, and the suspension part 4 and the barrier net 5 may be manufactured as a single unit.

[0035] It is understandable that the mounting component 13 may also be in other forms, and the device may not have a mounting base 14, with the suspension component 4 only fixed in position relative to the barrier net 5.

[0036] Understandably, the protective cover 3 can also be in other forms, as long as it can be fitted onto the suspension component 4.

[0037] It is understandable that buoy 2 may not have an opening 9.
