Description

Technical Field

[0001] The utility model belongs to the technical field of rubber dam bags, in particular to a rubber dam bag protection device. Background Art

[0002] Rubber dams are a new type of low-head water-retaining structure that emerged in the 1950s. They are constructed with a fiber cloth as the load-bearing framework and a vulcanized natural rubber layer as a water- or air-blocking protective layer. These are anchored to the riverbed foundation and end walls with embedded bolts, forming a sealed rubber bladder. By filling the bladder with water, air, or both, the flexible rubber structure acts as a water barrier. Rubber dams offer advantages such as a simple structure, low investment, short construction period, long service life, and easy operation and management.

[0003] Rubber dam bags are made by vulcanizing high-polymer rubber and canvas. The canvas serves as the bag's load-bearing framework, while the rubber acts as a bonding, water-stopping, and protective barrier. The service life of a rubber dam is affected by the installation environment. In some rivers with short flood seasons and long periods of dry weather, rubber dam bags are exposed to constant sunlight year-round. Affected by numerous factors, including atmospheric pressure, temperature, and sunlight, the rubber layer of the dam bag is susceptible to powdering, cracking, swelling, blistering, delamination, and rupture, gradually losing its original excellent properties and ultimately losing its usefulness, severely impacting the dam's service life. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a rubber dam bag protection device which can extend the service life of the rubber dam.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: it includes a dam bag body, the front end of the dam bag body is provided with an upstream anchor bolt, the rear end of the dam bag body is provided with a downstream anchor bolt, the dam bag body is provided with a protective cloth on the top of the protective cloth, a spray water pipe is provided on the protective cloth, the top end of the spray water pipe is connected to the water pump, and the tail end of the spray water pipe is connected to the spray heads evenly distributed on the dam bag body, the front end of the dam bag body is provided with an upstream mounting part, and the rear end of the dam bag body is provided with a downstream mounting part, the front end of the protective cloth and the upstream mounting part, and the rear end of the protective cloth and the downstream mounting part are respectively fixed by bolts, locks or bundling.

[0006] The present invention provides a rubber dam bag protective device. A protective cloth is provided on the dam bag body. A spray pipe is provided on the protective cloth. The top of the spray pipe is connected to a water pump, and the rear end of the spray pipe is connected to spray heads evenly distributed on the dam bag body. An upstream mounting portion is provided at the front end of the dam bag body, and a downstream mounting portion is provided at the rear end of the dam bag body. The front end of the protective cloth is secured to the upstream mounting portion, and the rear end of the protective cloth is secured to the downstream mounting portion, respectively, by bolts, locks, or strapping. During the flood season, the protective cloth is removed to prevent damage to the protective cloth, the spray pipe, and the spray head from turbulent water. During the dry season, the protective cloth is installed on the dam bag body via the upstream and downstream mounting portions. Water is pumped by the water pump through the spray pipe and the spray head, spraying water onto the protective cloth. The protective cloth absorbs water, simulating a submerged dam bag. After absorbing water, the protective cloth effectively protects the dam bag body from sunlight, slowing down the aging of the dam bag body and extending the service life of the rubber dam bag. The upstream installation part, downstream installation part, protective cloth, sprinkler pipe, sprinkler head, etc. are all standard products, and subsequent replacement is simple and convenient.

[0007] The rubber dam bag protection device provided by this utility model has upstream and downstream mounting parts that primarily serve to provide a foundation for connecting the dam bag body to the protective cloth. This can be achieved using a variety of techniques, including but not limited to bolts, locks, and strapping. The upstream and downstream mounting parts are made of rubber. During the dam bag production process for newly built rubber dams, the upstream and downstream mounting parts can be vulcanized onto the formed dam bag body. For rubber dams already in operation, the upstream and downstream mounting parts can be bonded to the existing dam bag body using cold adhesive during the dry season. The upstream and downstream mounting parts are available in a variety of styles, suitable for pillow-type and slope-type dam bags of various structures, making installation and replacement simple and convenient. The protective cloth is made of polyethylene (HDPE). After treatment with UV stabilizers and antioxidants, it possesses strong tensile strength, resistance to aging, corrosion, radiation, and portability, effectively blocking UV radiation. Black is the preferred color for the protective cloth. Black reflects sunlight less than any other color, but absorbs it most effectively, maximizing its energy consumption and protecting the dam bag from direct sunlight. The number of sprinkler pipes and sprinkler heads can be adjusted based on the water retaining height of the rubber dam. Since the rubber dam operates in a river environment, stainless steel sprinkler heads are preferred. Stainless steel sprinkler heads offer superior corrosion resistance and strength, enabling them to maintain stable performance over time in harsh environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The rubber dam bag protection device provided by this utility model allows the protective cloth 4 to be removed during the flood season to prevent turbulent water from damaging the protective cloth 4, the spray pipe 5, and the spray head 6. During the dry season, the protective cloth 4 is installed on the dam bag body 1 via the upstream mounting portion 7 and the downstream mounting portion 8. A water pump pumps water through the spray pipe 5 and the spray head 6, spraying the water onto the protective cloth 4. The protective cloth 4 absorbs water, simulating a submerged dam bag.
