Description

Technical Field

[0001] The invention belongs to the field of water conservancy structures and civil structures, and in particular designs a water bridge device that rises and falls with the water level. Background Art

[0002] A water bridge is not a bridge for transportation on the water surface. It is a small dock with steps from the water surface to the shore. It has been used by people since ancient times. In the Jiangnan region, water bridges can be seen everywhere in the rivers of waterfront cities. It is a place for nearby residents to get close to the river. The traditional water bridge is actually a step from the ground to the water surface. The last step is slightly wider or made into a small platform to facilitate people's activities near the water.

[0003] In the treatment of black and smelly rivers, in the treatment of beautiful villages, and in the river regulation, it is necessary to build more water bridges to maintain the original appearance of the rural rivers and facilitate people to enjoy the water. For example, in Fengxian, Qingpu, Songjiang, Jinshan and Minhang districts in Shanghai, there are many water bridges that need to be built. It can be seen that there are countless water bridges in the water towns and waterfront cities in the south of the Yangtze River. However, sometimes because water bridges are inconvenient to use, they can only be set up as little as possible. Therefore, it also blocks people from enjoying the water and reduces the quality of the river.

[0004] The top elevation of the existing water bridge platform is generally higher than the designed water level or the normal water level, and the platform height is fixed. Therefore, when the water level is low, the platform is far away from the horizontal plane and people cannot get close to the water. When the water level is high, the platform surface is often submerged by water, making it impossible for people to use the platform. After the water level drops, dirt remains on the platform surface, making it a mess. The platform is often immersed in water, causing the hydrophilic platform to be constantly damaged, posing a safety hazard to people's use.

[0005] Secondly, the last level platform of the existing water bridge needs a foundation, but because it is adjacent to the revetment, the platform is often broken or tilted, posing a major safety hazard. The existing water bridge platform construction is complex, and a temporary construction cofferdam needs to be set up during construction to ensure that the platform foundation and other structures can be constructed normally.

[0006] The above shows that the existing water bridge platform is greatly affected by the water level, it is difficult to exert true hydrophilicity, and there are safety hazards; the material and construction costs are high, the landscape effect is poor, and it is not worthy of its name, and it is difficult to meet people's hydrophilic and usage requirements. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a water bridge device that rises and falls with the water level, which ensures that the platform is not flooded and can truly exert its hydrophilicity at different water levels, while meeting the use requirements and providing people with a safe and reliable platform.

[0008] The technical solution is: a water bridge device that rises and falls with the water level includes steps fixed on the slope of the river channel, a floating platform arranged on the slope, and floating in the water area below the steps; a slide is arranged up and down along the slope of the river channel, respectively located on both sides of the steps; the floating platform is connected to the slide by a rotating rod to form a chain rod component to complete the buoyancy transmission.

[0009] Based on the above technical features: a roller, a roller shaft and a roller rod are provided in the slide groove; the roller rotates around the roller shaft and rolls along the slide groove; the roller rod is fixed to the roller shaft; the transverse shaft penetrates the floating platform transversely; one end of the rotating rod is hinged to the end of the transverse shaft, and the other end is fixed to the roller rod.

[0010] Based on the above technical features: the floating platform includes a main block located in the middle and auxiliary blocks located on both sides of the main block, the bottom of the auxiliary blocks is level with the static water level E; the bottom of the main block is lower than the static water level E.

[0011] Based on the above technical features: the front section of the main block is the overlapping section with the step, the height of the front section is the same as the height of the step, the rear section of the main block is the main buoyancy section, and the height of the rear section is greater than the height of the front section.

[0012] Based on the above technical features: the floating platform is a steel cage on the outside and filled with EPS foam board on the inside.

[0013] Based on the above technical features: the slide is a box body with a longitudinal groove on the upper plate surface, the roller rod passes through the longitudinal groove and can slide along the longitudinal groove.

[0014] The present invention is aimed at the water bridges in the prior art. The existing water bridges all adopt fixed structural forms, which cannot meet people's hydrophilicity and water operation. The present invention is composed of fixed steps and floating platforms. The floating platform floats on the water surface and together with the fixed steps on the bank slope, it constitutes a water bridge that can rise and fall with the water level. People can go to the riverside to relax at any time in their spare time. The floating platform brings people a unique experience and feeling. The design concept is to allow people to approach the river at different water levels and create a socially attractive place and leisure place around the river.

[0015] This water bridge device that rises and falls with the water level is suitable for new river bank protection, and is also suitable for adding to existing river bank protection, or rebuilding existing water bridges. No changes are needed to the existing bank protection structure. If there is no step, only steps need to be added, and a floating platform can be added at the same time. For bank protection with existing steps, only chutes and floating platforms need to be added on both sides of the steps.

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention provides a water bridge rising and falling technology according to the water level, providing a water bridge that automatically rises and falls according to the water level for urban citizens and tourists.

[0018] 2. The present invention uses the EPS foam board as the movable platform of the water bridge, fully utilizing the buoyancy of water to drive the platform to move up and down in sync with the water level, thus truly achieving hydrophilicity and making the water bridge truly hydrophilic.

[0019] 3. The chute fixed on the shore and the platform in the water are connected by sliding. One end of the platform rotating rod is hinged to the roller in the chute on the shore and can rotate up and down. The roller can slide straightly along the chute, and the platform rises and falls with the water level. At different water levels, the water bridge steps and the platform are always connected.

[0020] 4. The fixed chute not only limits the movement range of the platform, but also provides a sliding track for the platform to float up and down. The chute and roller configuration has strong applicability. The chute can be set obliquely to match the river slope; it can also be set vertically to match the vertical bank wall.

[0021] 5. Using EPS foam board as floating platform not only provides a movable platform, but also has its own buoyancy, so there is no need to set up buoyancy measures for the platform. The material is cheap and the production is simple. The chute, roller and floating platform can all be standardized and manufactured in the factory and installed on site.

[0022] 6. The water bridge that rises and falls with the water level has changed the traditional fixed construction mode of the water bridge. This change has greatly improved the overall function and design concept of the water bridge, which can improve the hydrophilicity of the water bridge, make it safe and reliable, and facilitate construction, saving engineering investment. Water bridges are widely used in urban rivers and lakes and have broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, but not to limit the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0033] The technical problem to be solved by the present invention is that traditional water bridges all adopt fixed structural forms, which cannot meet people's use needs and have potential safety hazards. Figure 1 As shown, the present invention is composed of a fixed step 4 and a floating platform 1. The fixed step 4 is a conventional component, and the main content of the present invention is the floating platform 1 in the water bridge device. The floating platform 1 floats on the water surface, and together with the fixed step 4 on the river slope 14, constitutes a water bridge device that can rise and fall with the water level. The upper side of the river slope 14 is the ground or the top of the embankment D, and the lower side is the river bottom B.

[0034] 1. Main components and their functions

[0035] (1) Floating platform 1

[0036] like Figure 1 As shown, the floating platform 1 generally includes a main body block 2 located in the middle and auxiliary blocks 3 located on both sides of the main body block. The floating platform 1 provides a water carrier for human activities. Figure 4As shown in the figure, the horizontal section (i.e., along the river direction) of the floating platform is T-shaped, with auxiliary blocks 3 on both sides of the main block 2. The bottom of the main block 2 is lower than the static water level E; the bottoms of the auxiliary blocks 3 on both sides are level with the static water level E. When the personnel load on the platform is biased to one side, the auxiliary blocks 3 immediately generate anti-tilting buoyancy to keep the platform from tilting. Therefore, the length L1 of the auxiliary blocks is determined by the buoyancy required for anti-tilting.

[0037] The floating platform 1 composed of the main block 2 and the auxiliary block 3 can be composed of a steel cage 5 filled with EPS foam board 6. The shape of the steel cage 5 can be determined according to the shape of the floating platform 1.

[0038] The EPS foam board 6 is a lightweight material with low water absorption, corrosion resistance, antifreeze, oxidation resistance, and UV resistance. It is not eroded by seawater, chemicals, oil stains, and aquatic organisms; it is pollution-free and does not damage the environment; it is light in weight and has high mechanical strength. Its service life is at least 10 years, and it requires almost no maintenance and repair costs except for strong natural forces and improper human use. The floating platform 1 is easy to assemble, fast, flexible, and has a variety of shapes. The overall modular structure can be used to determine the size and shape of the steel cage in accordance with the needs of various conditions; it is cheap and can save the cost and time of maintenance, replacement, and overhaul.

[0039] The steel cage 5 is woven from a mesh, which can be made of Φ3-5×Φ3-5 cold-drawn hot-dip galvanized steel wire, and is made by resistance welding. The top plate, such as the waterproof and anti-slip plate 7, should have a certain rigidity and be consolidated with the steel cage 5. Rope-type railings can be set around the platform.

[0040] like Figure 2 and Figure 3 As shown, the vertical section of the main block 2 is in the shape of a step, and the front section is overlapped with the step 4 so as to rise and fall with the water level, so that the floating platform 1 can be matched with the fixed step 4. Figure 5 As shown, the front section height h of the main block 2 is preferably equal to the step height of the step 4, and the rear section height H of the main block 2 should be determined according to the required buoyancy calculation. The front section bottom and the rear section bottom of the main block can be formed by a 45-degree cut angle transition.

[0041] (2) Transverse axis 8

[0042] like Figure 1 and Figure 5 As shown, the transverse shaft 8 is installed at the shore end of the floating platform 1, penetrates the main block 2 transversely, and is fixed to the main block 2, with both ends exposed from the sides of the main block 2 as rotating hinge ends. The transverse shaft 8 is preferably a galvanized pipe, and its diameter is preferably selected according to the length, that is, the larger the length, the larger the diameter.

[0043] The main function of the transverse shaft 8 is to transfer the buoyancy of the platform to the rotating rod 9 and connect the floating platform 1 to the slope through the rotating rod 9.

[0044] (3) Rotating rod 9

[0045] like Figure 5 and Figure 6 As shown, the rotating rod 9 is installed on both sides of the end of the main body block 2 of the floating platform, one end is hinged to the transverse axis 8, and the other end is installed at the end of the roller rod 12. The end of the rotating rod 9 can rotate around the transverse axis 8 to transfer the buoyancy of the platform to the roller rod 12, so that the roller 10 rolls along the slide 11. The length of the rotating rod 9 should be determined according to the horizontal distance between the inner side of the floating platform 1 and the slide 11.

[0046] (4) Chute 11

[0047] like Figure 5 and Figure 6 As shown, the chute 11 is concave and made of steel or plastic steel. The chute 11 is both a track for the roller 10. The roller 10 slides up and down with the change of water level and the buoyancy provided by the floating platform 1; and it is also a pulling structure of the floating platform 1, which keeps the floating platform 1 at the front of the step at any water level and does not float at will. Several concrete blocks are set at the bottom of the chute 11 and buried in the river bank slope. Embedded parts are set in the concrete blocks, and the chute 11 is connected to the embedded parts, so that the chute 11 is fixed on the bank slope. The width of the upper plate opening of the chute 11 should be greater than the diameter of the roller rod 12 to meet the operation of the roller rod 12.

[0048] The chute 11 is a concave empty box, and the upper and lower plates are the tracks of the roller 10. For example, when the floating platform 1 rises, it drives the rotating rod 9 to move upward, and the roller 10 rolls on the bottom plate of the chute 11; when the floating platform 1 drops with the water level, the rotating rod 9 moves downward, and the roller rolls on the upper plate bottom of the chute 11. The chute length L should be determined based on the highest water level C, the lowest water level A and the slope ratio, that is: chute length L = (highest water level C-lowest water level A) × (1+m 2 )1 / 2+△L, where m is the slope rate; △L is the extended length, generally about 0.2m at both ends. When it is a vertical revetment, m=0.

[0049] (5) Roller 10

[0050] like Figure 6As shown, the roller 10 is composed of a roller shaft 13, a roller rod 12 and a roller 10. The roller 10 is mounted on one end of the rotating rod 9 at the end of the floating platform 1, and can roll along the bottom plate or the bottom of the upper side plate in the chute 11. Under the action of buoyancy, the floating platform 1 transmits the buoyancy to the rotating rod 9 through the transverse shaft 8, and then the rotating rod 9 transmits it to the roller 10, thereby driving the roller 10 to run along the track of the chute 11. The size of the roller 10 should match the chute 11.

[0051] There are two rollers 10, which are mounted on roller shafts 13 and rotate around roller shafts 13. Roller shafts 13 are fixed to roller rods 12, roller rods 12 are fixed to rotating rods 9, and rotating rods 9 are hinged to transverse shafts 8. Thus, a chain rod component is formed to complete the transmission of buoyancy.

[0052] The cross section of the slide groove 11 is similar to a box, and can provide support for the roller on all sides. Therefore, even when the force is unbalanced, there will be no obstruction between the roller 10 and the slide groove 11.

[0053] 2. Working Principle

[0054] A water bridge device that rises and falls with the water level, comprising a step 4 fixed on a river slope 14, and a floating platform 1 arranged on the slope, floating on the water area below the step 4; the device is provided with buoyancy by the floating platform, and rises and falls with the water level by utilizing the buoyancy of water, without providing power; it floats on the water surface at all times, providing a suitable place for people to relax and carry out activities.

[0055] The rotating rods 9 on both sides of the main block 2 of the floating platform 1 ensure the stability of the floating platform 1, the EPS foam board provides buoyancy for the floating platform 1, the slide 11 provides a support for the floating platform 1, and the rollers 10 connected to the rotating rods 9 move along the slide 11 and move up and down with the water level, thereby forming a floating platform.

[0056] The rotating rod 9 connects the floating platform 1 with the roller 10. Since both ends are hinged to the transverse shaft 8 and the roller 10 respectively, only the axial force generated by the buoyancy of the floating platform 1 is transmitted, and no bending moment is transmitted.

[0057] The floating platform 1 moves up and down with the water level, and its buoyancy is transmitted from the transverse shaft 8 to the rotating rod 9, and then from the rotating rod 9 to the roller 10, thereby pushing the roller 10 to roll along the slide groove 11.

[0058] The slide groove 11 and the roller 10 are both walking components and limiting components, which restrict the platform to float up and down only in front of the two slide grooves, that is, to move forward and backward on the step 4, but not to float at will.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
