Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering equipment technology, and particularly to the field of water conservancy engineering equipment technology for emergency rescue and disaster relief in mountainous areas. Specifically, it relates to a portable water-filled river crossing device for emergency crossing in narrow river valleys in treacherous mountainous areas. Background Technology

[0002] Due to the steep terrain, narrow river valleys in rugged mountainous areas are often the only access routes. In the event of natural disasters such as earthquakes, mudslides, and landslides, as well as man-made disasters such as war or fires, the key to disaster relief in these areas lies in how to quickly clear these river valleys to ensure the passage of rescue personnel and supplies and to buy as much time as possible for the critical 72-hour rescue window.

[0003] Rapid river-crossing devices have made it possible to quickly clear treacherous mountain valleys. To achieve rapid river crossing, a series of rapid river-crossing devices have been developed, including belt bridges, truss bridges, lightweight pontoon bridges, tank-assisted bridges, lightweight pontoon bridges, and self-propelled pontoon bridges. However, due to limitations in size, weight, and transportation requirements, these existing rapid river-crossing devices cannot be applied to the rapid clearing of narrow, treacherous mountain valleys with restricted terrain.

[0004] Therefore, in response to the practical engineering need of quickly and easily opening up river valleys in difficult mountainous areas, there is an urgent need to develop a river-crossing device that can quickly and conveniently open up river valleys in difficult mountainous areas.

[0005] To address the aforementioned problems, this invention provides a portable water-filled river-crossing device for emergency crossings in narrow, treacherous mountain valleys. It creatively proposes a novel emergency crossing device for such passages, differing significantly from existing devices in that it is lightweight, portable, and easy to transport; it features flexible contact, adapting well to the complex terrain of narrow, treacherous mountain valleys; it is easy to set up, saving time during emergency operations; and it is reusable. This novel crossing device meets the basic requirements of a high-performance emergency crossing device: high sensitivity, high adaptability, low installation difficulty, and low maintenance costs. It provides a portable water-filled river-crossing device suitable for emergency crossings in narrow, treacherous mountain valleys used in water conservancy projects. Summary of the Invention

[0006] The purpose of this invention is to provide a portable water-filled river-crossing device for emergency crossing in narrow valleys and dangerous mountainous areas. This invention solves the problems of existing river-crossing devices for emergency crossing in narrow valleys and dangerous mountainous areas being complicated, cumbersome to set up, and unable to cross rivers quickly. The invention provides a portable water-filled river-crossing device for emergency crossing in narrow valleys and dangerous mountainous areas that is easy to set up and convenient to use.

[0007] To achieve the above objectives, the present invention provides a portable water-filling river-crossing device for emergency crossing in narrow valleys and dangerous mountainous areas. It mainly consists of three parts: the lower quick-fill water bag structure, the upper detachable titanium alloy bridge plate structure, and the high-pressure water pump. Specifically, it includes the following structures.

[0008] The lower quick-fill water bag structure is the core component of the portable water-filling river-crossing device used for emergency crossing in narrow river valleys in treacherous mountainous areas. It is used to store river water, support the upper passage load, achieve contact with the river surface, maintain the size and shape of the lower quick-fill water bag structure, and form a flat upper surface, which can be used as a temporary water bridge device for disaster relief personnel and vehicles to move forward.

[0009] Furthermore, the water bag shell, as the external structure of the lower fast-charging water bag structure, is made of wear-resistant rubber to improve the wear resistance of the water bag shell and enhance the durability of the lower fast-charging water bag structure. The water bag shell is provided with a wear-resistant rubber outer layer, a load-bearing layer, and a buffer layer from the outside to the inside. The wear-resistant rubber outer layer of the water bag shell is pressed with rib-shaped reinforcing patterns to alleviate external load impacts and withstand various deformations, loads, forces, and high and low temperature effects caused by river water impact pressure and the passage of rescue personnel and vehicles.

[0010] Furthermore, the load-bearing layer of the water bag shell is made of multiple layers of gelled cotton yarn or aromatic polyamide arranged at 90° intervals, which is used to evenly distribute the internal water pressure, upper load and impact force of personnel and vehicles passing through the water bag shell.

[0011] Furthermore, the water bag shell buffer layer is made of highly elastic buffer rubber and is disposed between the water bag shell wear-resistant rubber outer layer and the water bag shell load-bearing layer to strengthen the bond between the water bag shell wear-resistant rubber outer layer and the water bag shell load-bearing layer, and to prevent the water bag shell wear-resistant rubber outer layer from separating from the water bag shell load-bearing layer when the disaster relief vehicle brakes in an emergency.

[0012] Furthermore, the water storage inner bag is made of high-elasticity and high-toughness rubber, and the inner wall of the water storage inner bag is provided with a 2mm to 3mm thick water-sealing rubber sealing layer to increase air tightness; and the inner surface of the water-sealing rubber sealing layer is provided with the dual-core microcapsule self-healing layer, so that when the water storage inner bag is punctured, it can automatically seal the punctured hole.

[0013] Furthermore, the microcapsules of the dual-core microcapsule self-healing layer have a diameter of 60μm to 80μm and a wall material of urea-formaldehyde resin. The core material of the dual-core microcapsule is epoxy resin E-44, and the second core material is tetraethylenepentamine.

[0014] Furthermore, the water inlet / outlet is equipped with a cylindrical plug valve and a flow regulating valve to adjust the flow rate of the high-pressure water pump. The cylindrical plug valve and the flow regulating valve are sealed by an oil-lubricated hard seal. The oil-lubricated hard seal can effectively prevent lubricating oil from leaking out of the valve and prevent external dust, moisture and other impurities from entering the valve, thereby keeping the valve clean and extending its service life.

[0015] Furthermore, six water inlets and outlets are evenly arranged longitudinally along the bottom of the lower quick-fill water bag structure. These water inlets and outlets are connected to the high-pressure water pump via high-strength and high-toughness rubber water pipes to enable rapid water inlet and outlet filling of the water storage inner bag.

[0016] The upper detachable titanium alloy bridge plate structure is assembled from titanium alloy plates and is parallel to the upper surface of the lower fast-filling water bag structure through the detachable fasteners.

[0017] Furthermore, the upper detachable titanium alloy bridge deck structure is lightweight and high-strength, used to bear the upper traffic load; the dimensions of the titanium alloy plate are 30-80mm thick × 1000mm wide × 2000mm long; the upper detachable titanium alloy bridge deck structure is assembled by bolting titanium alloy plates to ensure the good strength and stability of the upper detachable titanium alloy bridge deck structure and to prevent the titanium alloy plates from being stretched, compressed and torn.

[0018] Furthermore, in actual use, the size of the detachable titanium alloy bridge deck structure can be adjusted according to the actual river crossing requirements to adapt to the variability of the river crossing environment.

[0019] Furthermore, the lower quick-fill water bag structure and the upper detachable titanium alloy bridge plate structure are connected by the tool-free disassembly system set on the upper surface of the water bag shell, which is used to achieve the uniformity and integrity of the portable water-filling river crossing device for emergency crossing in narrow river valleys in treacherous mountainous areas; a high-toughness buffer rubber pad is provided between the lower quick-fill water bag structure and the upper detachable titanium alloy bridge plate structure to buffer the impact of the passing load.

[0020] Furthermore, the tool-free disassembly system is composed of spiral steel nails, washers, and bends; the spiral steel nails, washers, and bends are all made of stainless steel, which facilitates installation and extends the service life of the tool-free disassembly system; the tool-free disassembly system is evenly arranged along the lower quick-fill water bag structure at longitudinal intervals of 1m and transverse intervals of 2m.

[0021] As can be seen, the portable water-filled river-crossing device for emergency crossing in dangerous mountainous and narrow river valley passages of the present invention can be set up immediately after stopping, has high mobility, simple structure, and is easy to operate, and can meet the needs of water conservancy projects for rapid river crossing.
