Description

Technical Field

[0001] The utility model relates to the technical field of floating barrier devices, in particular to a floating box with adjustable inclination and a floating barrier row including the floating box. Background Art

[0002] At present, when using a floating barrier row to intercept floating objects, in the case of high water flow velocity, the floating boxes of traditional floating barrier rows are prone to tipping over and being damaged, resulting in the floating barrier row losing its interception function and possibly causing unforeseen accidents.

[0003] In the prior art, there is a Chinese utility model patent document with the publication number CN203684187U and the publication date of July 2, 2014. The technical solution disclosed in this patent document is as follows: End connection devices are respectively arranged at both ends of a box body for a floating barrier device. A hanging grid is arranged on one side of the floating box, a counterweight box is arranged on the other side of the floating box, and a railing is arranged on the top of the floating box.

[0004] In the prior art, there is also a Chinese utility model patent document with the publication number CN205819502U and the publication date of June 30, 2016. The technical solution disclosed in this patent document is as follows: A floating box of a floating object interception device includes a floating body part, a counterweight part, and a connecting part. The connecting part is arranged obliquely above the upstream part of the floating body, and the counterweight part is arranged on one side of the floating body part away from the connecting part.

[0005] The above technical solutions all adopt a counterweight box or a counterweight part, the purpose of which is to balance the weight on the side of the box body opposite to the side where the hanging grid is arranged, ensure that the center of gravity is always at the center of the floating box, or to move the center of gravity position of the floating box backward, reduce the impact force of water on the floating box, and enhance the ability of the floating box to resist tipping over by water impact.

[0006] However, regardless of the purpose for which the counterweight box or the counterweight part is set, during the use of the floating box, due to the non-adjustable counterweight, the floating box can only maintain balance at a specific water flow velocity and cannot maintain balance under the impact of different water flow velocities. Summary of the Invention

[0007] To solve the above technical problems, the utility model provides a floating box with adjustable inclination and a floating barrier row including the floating box, which can effectively solve the problem that the existing floating boxes and floating barrier rows cannot maintain balance under the impact of different water flow velocities.

[0008] The utility model is realized by adopting the following technical solutions:

[0009] A floating box with adjustable inclination includes a floating box body, a ballast tank communicating with each other, and a water injection / drainage device; the ballast tank is arranged on one side of the floating box body away from the water-facing side; the water injection / drainage device is configured to inject water or drain water into the ballast tank.

[0010] A hanging grid is also arranged on one side of the floating box body close to the water-facing side.

[0011] The width of the hanging grid is greater than the width of the floating box body.

[0012] The width of the floating box body is 30% - 60% of the width of the hanging grid.

[0013] A balance floating box is also arranged between the floating box body and the ballast tank.

[0014] The depth of the hanging grid immersed in water is greater than 2m.

[0015] Reinforcing ribs are also arranged between the hanging grid and the floating box body.

[0016] It also includes a horizontal sensor.

[0017] The water injection / drainage device includes a water pump, a ventilation pipe, and two connecting pipes respectively connected to the water pump. One connecting pipe communicates with the ballast tank, and the other connecting pipe communicates with the water body outside the floating box. The ballast tank communicates with the atmosphere through the ventilation pipe.

[0018] A floating debris barrier includes the above-mentioned floating box.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. In the present utility model, the ballast tank is arranged on one side of the floating box body away from the water-facing side, and water is injected or drained into the ballast tank through the water injection / drainage device. During the operation of the floating box, the adjustment of the counterweight of the ballast tank can be realized. Under the impact of different water flow velocities, the inclination angle of the floating box is adjusted by injecting or draining water to keep the floating box balanced. Specifically, when encountering the impact of high-speed water flow, the whole floating box will form a certain inclination angle. At this time, the water injection / drainage device injects water into the ballast tank to increase the counterweight at one end of the floating box away from the water-facing side, so that the floating box remains balanced. If one end of the floating box away from the water-facing side is too heavy, the ballast tank is drained through the water injection / drainage device to rebalance the floating box.

[0021] 2. In the present utility model, floating dirt can be intercepted by arranging the hanging grid.

[0022] 3. In the prior art, the width of the hanging grid is generally about the same as the width of the floating box body. The present utility model breaks the conventional setting. Without changing the width of the hanging grid, the width of the floating box body is designed to be smaller than that of the conventional floating box body, so that the width of the hanging grid is greater than the width of the floating box body. As a result, a water passage can be formed between two adjacent floating box bodies, reducing water resistance and thus reducing the overall force on the floating debris barrier including the floating box.

[0023] 4. The width of the floating box body is 30% - 60% of the width of the hanging grid, which can better maintain the balance between reducing water resistance and the stability of the floating box.

[0024] 5. Compared with the conventional floating box, the present utility model adds a balancing floating box, increasing the overall length of the floating box, making the control of the tilt angle of the floating box more controllable and facilitating better maintenance of the balance of the floating box.

[0025] 6. In the prior art, the depth of the conventional hanging grid submerged in water can generally only be set between 1.2 m and 1.5 m. In the present utility model, since the floating box can adaptively adjust the balance, and the overall width of the floating box is narrower and the length is longer, the depth of the hanging grid submerged in water can be deeper, that is, the depth of the hanging grid submerged in water can be greater than 2 m, which can increase the interception depth of floating debris and improve the interception efficiency.

[0026] 7. The setting of the reinforcing ribs makes the structure of the hanging grid more stable.

[0027] 8. The present utility model is also provided with a horizontal sensor, which can detect the tilt angle of the floating box, enabling more accurate control of the water injection volume or drainage volume.

[0028] 9. The floating debris barrier includes the above-mentioned floating box, enabling this floating debris barrier to adapt to water flow impacts at different speeds or even higher speeds, with a wider adaptation range. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 1

[0038] As a basic embodiment of the present utility model, the present utility model includes a floating box with an adjustable inclination, which includes a floating box body 2, a ballast tank 3 and a water injection / drainage device. Specifically, the water injection / drainage device can be arranged on the ballast tank 3 or on the floating box body 2. The ballast tank 3 is communicated with the water injection / drainage device, and the water injection / drainage device is also communicated with the water body outside the floating box 1, so that the water injection / drainage device can be configured to inject water into or drain water from the ballast tank 3. Specifically, the water injection / drainage device can adopt conventional technical means in the art, for example, it can include: a water injection pump, a drainage pump, a water injection pipeline and a drainage pipeline, etc. The water injection pump is respectively communicated with the ballast tank and the water body outside the floating box 1 through the water injection pipeline, and is used to inject the water outside the floating box 1 into the ballast tank 3. The drainage pump is respectively communicated with the ballast tank 3 and the water body / atmosphere outside the floating box 1 through the drainage pipeline, and is used to drain the water in the ballast tank 3 to the outside.

[0039] More specifically, the ballast tank 3 is arranged on the side of the floating box body 2 away from the water-facing side. When the floating box 1 is unbalanced under the impact of different water flow velocities, that is, the floating box 1 forms a certain inclination, according to the inclination, water is injected into the ballast tank 3 to increase the weight of the ballast tank 3, or the ballast tank 3 is drained to reduce the weight of the ballast tank 3, so as to achieve the balance of the floating box 1.

[0040] Embodiment 2

[0041] As a preferred embodiment of the present utility model, the present utility model includes a floating box with an adjustable inclination, which includes a floating box body 2, a ballast tank 3 and a water injection / drainage device. The ballast tank 3 is arranged on the side of the floating box body 2 away from the water-facing side, and a hanging grid 4 is also arranged on the side of the floating box body 2 close to the water-facing side. The water injection / drainage device is communicated with the ballast tank 3 and is configured to inject water into or drain water from the ballast tank 3, so that the configuration of the ballast tank 3 can be adjusted.

[0042] Furthermore, the width of the hanging grid 4 is greater than the width of the floating box body 2, so that a water passing channel is formed between the floating box bodies 2 of two adjacent floating boxes 1.

[0043] Embodiment 3

[0044] As another preferred embodiment of the present utility model, the present utility model includes a floating box with adjustable inclination, which includes a floating box body 2, a balancing floating box 5, a ballast tank 3 and a water injection / drainage device. The ballast tank 3 is arranged on one side of the floating box body 2 away from the water-facing side, and the balancing floating box 5 is arranged between the floating box body 2 and the ballast tank 3. The water injection / drainage device is arranged on the balancing floating box 5. The water injection / drainage device is respectively communicated with the ballast tank 3 and the water body outside the floating box 1, and is configured to inject water or drain water into the ballast tank 3. Wherein, each floating box 1 can include a water injection / drainage device, or two or more adjacent floating boxes 1 can also share the same water injection / drainage device.

[0045] In order to better control the water injection and drainage of the water injection / drainage device, a horizontal sensor can also be arranged on each floating box 1 for detecting the inclination angle of the floating box 1.

[0046] Embodiment 4

[0047] As the best embodiment of the present utility model, the present utility model includes a floating box with adjustable inclination, referring to the attached Figure 1 and the attached Figure 2 , which includes a floating box body 2, a balancing floating box 5, a ballast tank 3 and a water injection / drainage device. Among them, the ballast tank 3 is arranged on one side of the floating box body 2 away from the water-facing side; the balancing floating box 5 is arranged between the floating box body 2 and the ballast tank 3. A hanging grid 4 is also arranged on one side of the floating box body 2 close to the water-facing side.

[0048] Specifically, the floating box body 2 adopts conventional technical means in the art. For example, the floating box body 2 can be arranged in a cylindrical shape. Anti-sinking materials, such as high molecular weight polyethylene materials, are filled in both the floating box body 2 and the balancing floating box 5.

[0049] The width of the hanging grid 4 is greater than the width of the floating box body 2. More specifically, the width of the floating box body 2 is 30% - 60% of the width of the hanging grid 4, so that a water passage is formed between two adjacent floating box bodies 2, which can reduce the water resistance.

[0050] The water injection / drainage device includes a water pump 9, a ventilation pipe 10 and two connecting pipes respectively connected to the water pump 9. The water pump 9 can be arranged on the top of the ballast tank 3. One of the connecting pipes extends into the liquid level in the ballast tank 3 and is communicated with the ballast tank 3. The end of the other connecting pipe is located below the water surface outside the floating box 1 and is communicated with the water body outside the floating box 1. The ventilation pipe 10 can be located on the top of the ballast tank 3, so that the ballast tank 3 is communicated with the atmosphere through the ventilation pipe 10. Since there is a certain distance between the upper surface of the ventilation pipe 10 and the upper surface of the ballast tank 3, it can ensure that when the floating box 1 is inclined, water will not enter the ballast tank 3 through the ventilation pipe 10.

[0051] Further, filters are provided at both the inlet and outlet of the connecting pipe. A single water pump 9 can also fill or drain multiple ballast tanks 3 through connecting branches.

[0052] Refer to the appended Figure 3 and the appended Figure 4 of the specification. When the floating box 1 encounters the impact of high-speed water flow, the entire floating box 1 will form a certain inclination angle. At this time, the water pump 9 is started to inject water into the ballast tank 3, increasing the counterweight at the rear end of the floating box 1, that is, the end far from the water-facing surface, so as to keep the floating box 1 balanced. If the rear end of the floating box 1 is too heavy, the ballast tank 3 is drained through the water pump 9 to rebalance the floating box 1.

[0053] Since the floating box 1 can adaptively adjust the balance and the floating box 1 is narrower in width and longer in length, the underwater part of the hanging grid 4 can be lengthened to increase the interception depth of floating objects on the water surface and improve the interception efficiency. More specifically, the depth of the hanging grid 4 invading underwater can be greater than 2 m. To improve the connection stability of the hanging grid 4, a reinforcing rib 6 is also provided between the hanging grid 4 and the floating box body 2.

[0054] To better detect the inclination angle of the floating box 1, a horizontal sensor (inclination sensor) is also provided on the floating box 1.

[0055] Further, for automatic adjustment, a controller can also be provided. The controller is respectively connected to the horizontal sensor and the water pump 9. When the horizontal sensor detects that the inclination angle of the floating box 1 exceeds the set range, the water pump 9 is turned on to achieve water injection or drainage until the inclination angle of the floating box 1 reaches within the set range and stops. Through this structure, automatic control can be achieved and manual intervention can be reduced.

[0056] Embodiment 5

[0057] As another preferred embodiment of the present invention, the present invention includes a floating debris barrier. Refer to the appended Figure 5 of the specification, which includes an anchoring device 8, a steel wire rope 7, and several floating boxes 1 described in any one of Embodiments 1 to 4. Among them, the anchoring device 8 is fixed on the left and right anchoring piers. After the steel wire rope 7 is successively connected to the floating boxes 1, it is fixed on the anchoring device 8.

[0058] In summary, after those of ordinary skill in the art read the documents of the present invention, all other corresponding transformation schemes made without creative mental labor according to the technical solutions and technical concepts of the present invention fall within the scope protected by the present invention.
