Description

Technical Field

[0001] The invention relates to the technical field of water surface floating object interception equipment, in particular to a floating box and a floating interception row capable of preventing freezing damage. Background Art

[0002] When water freezes, its volume will increase by about 9%, and it will generate a strong expansion force during the freezing process. According to data, the expansion force of 1 gram of water when it freezes is 960 kilograms per square centimeter, which is equivalent to 960 atmospheres of pressure. The lower the temperature, the greater the expansion force, and it can even reach 2,500 atmospheres of pressure in a confined space. In the winter in the north, the surface of the river is almost always frozen. The principle of the traditional floating raft is almost to use the buoyancy generated by the larger drainage volume formed by the larger sealed space inside the box to make the floating raft float on the water surface as a whole to intercept floating objects. It has good sealing and can withstand certain water flow impacts, but it cannot withstand the larger extrusion force around the outside. For example, the expansion force generated by the freezing process of the river water is likely to cause the box to be squeezed, torn and damaged, and no longer have sealing properties. When the temperature rises and the river ice thaws, the water enters the inner cavity and the floating box loses its buoyancy, submerges below the water surface, and loses its function of intercepting floating objects.

[0003] When a large number of pontoons lose their buoyancy, the weight of the floating barrier is too great, which may damage the anchor piers and cause the floating barrier to sink and wash away as a whole, causing huge losses and threatening the safety of the power station. At present, if the floating barrier is used in a river basin that freezes in winter, it is usually necessary to dismantle and decompose the floating barrier as a whole before the river basin enters the freezing period, and then find a place to store it. It will be installed again after the temperature rises and the river ice thaws. The whole process is very time-consuming, labor-intensive and costly, with a huge amount of work and high safety risks, but it has to be done. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a buoyancy box and a floating barrier that can prevent damage by freezing. When the river basin is frozen, there is no need to dismantle the floating barrier, which greatly saves costs and reduces safety risks.

[0005] The present invention is achieved by adopting the following technical solutions: A pontoon capable of preventing damage by freezing comprises a pontoon body, wherein side panels and / or a bottom panel of the pontoon body are provided with through holes, through which an inner cavity of the pontoon body is connected to an external water environment; the inner cavity of the pontoon body is also filled with anti-sinking material, through which the pontoon floats on the water surface.

[0006] The buoyancy box body also includes a frame structure, and the side plates and the bottom plate are respectively connected to the frame structure.

[0007] The top cover of the buoyancy box body is detachably connected to the frame structure.

[0008] A wire rope suspension structure is also provided on the top of the buoyancy box body on the side close to the water surface.

[0009] The frame structure is also provided with reinforcing ribs.

[0010] The buoyancy tank body is a metal structure.

[0011] A hanging fence is also provided on the water-facing surface of the buoyancy box body.

[0012] A flexible chain net is also provided between two adjacent hanging fences.

[0013] A floating barge capable of preventing damage from freezing comprises the above-mentioned floating box capable of preventing damage from freezing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, since the side plates and / or the bottom plates are provided with through holes, the inner cavity of the pontoon body is connected with the external water environment through the through holes, so that river water can enter the pontoon body through the through holes. The anti-sinking material is filled in the inner cavity of the pontoon body to generate sufficient buoyancy to support the entire pontoon floating on the water surface, and there is a certain proportion of residual buoyancy to ensure the normal use of the pontoon.

[0015] When the basin enters the freezing season, since the internal and external water bodies are connected, the pressure inside and outside the pontoon is balanced when ice forms, so the pontoon will not be damaged; since the anti-sinking material has great elasticity, when the water body in the pontoon freezes, the expansion of the water will not cause damage to the anti-sinking material. Based on this, the pontoon of the present invention does not need to be dismantled when the basin is frozen, which greatly saves costs and reduces safety risks.

[0016] 2. In the present invention, the stability of the pontoon structure can be improved by setting up the frame structure, so that the pontoon can withstand the floating load.

[0017] 3. The top cover of the pontoon body and the frame structure are detachably connected, which is convenient for better installation and replacement of anti-sinking materials.

[0018] 4. A wire rope suspension structure is also provided on the water-facing side of the top of the pontoon body to improve the stability of the pontoon in the water and to connect all pontoons into a whole that can intercept drift.

[0019] 5. The frame structure is also provided with reinforcing ribs to further improve the stability of the pontoon structure.

[0020] 6. A hanging fence is also provided on the water-facing surface of the pontoon body to better intercept floating objects.

[0021] 7. A flexible chain net is also provided between two adjacent hanging fences to fill the gap between the hanging fences and ensure that the entire intercepting cross section can intercept floating objects.

[0022] 8. The floating barrier in the present invention has an anti-freezing buoyancy box, which does not need to be removed when the river basin is frozen, which can greatly save costs and reduce safety risks. BRIEF DESCRIPTION OF THE DRAWINGS
