[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0031] In the related art, the railings are generally set at the height of the highest water level, so as to ensure that the railings still have a certain interception effect on the river water at the highest water level. However, the water level of the river is variable. When the water level is low, the higher part of the valley slope is separated from the river water. On the one hand, the viewing experience is greatly reduced. On the other hand, the distance between the river bank and the water surface is large, which is not convenient for people to engage in water activities.

[0032] like Figure 1 to Figure 3 As shown, in one embodiment of a buoyancy device provided by the present invention, the buoyancy device includes a reset device and a plurality of buoyancy members 1 which are sealed and connected in sequence; the buoyancy member 1 is used to be rotatably connected to a river bank 2, and the buoyancy member 1 has a water retaining working surface; the reset device is used to be installed on a fixed basis, and it is connected to the buoyancy member 1 so that the buoyancy member 1 has a tendency to rotate toward the water surface.

[0033] In the embodiment of the present application, the water-retaining working surface on the buoyancy member 1 is mainly used to block the river water to prevent the river water from overflowing to the river bank 2 when the water level is high. The buoyancy member 1 has a continuous surface of a certain height in the direction perpendicular to the water surface. The continuous surface can be a plane, a curved surface or a folded surface. Due to the buoyancy of the river water, the continuous surface is always located above the water surface to achieve its blocking of the river water. The buoyancy member 1 and the river bank 2 can be sealed to prevent the river water from overflowing to the river bank 2. For example, a flexible sealing material is filled between the buoyancy member 1 and the river bank 2. In the vertical direction, the flexible sealing material can be located above the buoyancy member 1 or below the buoyancy member 1. In order to prevent the rotating connection structure between the buoyancy member 1 and the river bank 2 from being soaked in the river water, the setting position of the flexible sealing material is located below the buoyancy member 1.

[0034] The specific structure or setting position of the reset device in the embodiment of the present application may not be limited, as long as it can make the buoyancy member 1 have a tendency to rotate close to the water surface, that is, the rotation direction of the buoyancy member 1 under the action of the reset device is opposite to the rotation direction of the buoyancy member 1 under the buoyancy of the river water, so as to ensure that the buoyancy member 1 is always located on the water surface when the river water level is low. The reset device can make the buoyancy member 1 have a tendency to rotate close to the water surface by applying elastic tension or elastic thrust to the buoyancy member 1.

[0035] The buoyancy device provided in the embodiment of the present application is configured such that after the buoyancy member 1 is rotatably connected to the river bank 2, during the stage of rising water level, the buoyancy member 1 can rotate relative to the river bank 2 under the action of the buoyancy of water, thereby preventing river water from overflowing; during the stage of falling water level, the buoyancy member 1 rotates toward the water surface under the action of the resetting device, and the overall height of the buoyancy member 1 decreases, thereby ensuring the hydrophilicity of the river bank 2; and according to the change of water level, the buoyancy member 1 has a dynamic protection height under the action of the buoyancy of water, and its own installation height requirement is relatively low. During installation, there is no need to adjust the height of the river bank 2 itself, and the construction is relatively convenient.

[0036] In a possible embodiment, when the reset device applies a pulling force to the buoyancy member 1 so that the buoyancy member 1 has a tendency to rotate close to the water surface, a positioning block 5 can be set at the river bottom 7 or the valley slope, and an elastic member is connected between the positioning block 5 and the buoyancy member 1. The elastic member can be a tension spring 4, an elastic rod or an elastic rope. According to the relative positions of the connection points of the elastic member with the buoyancy member 1 and the positioning block 5, the direction of the elastic force provided by the elastic member to the buoyancy member 1 is also different. When the buoyancy member 1 starts to rotate in the installed state, its rotation direction is generally vertical. The connection line between the connection points of the elastic member with the buoyancy member 1 and the positioning block 5 is also set to be vertical, so that the effectiveness of the elastic force of the elastic member can be greater. For example, in a possible implementation method, the positioning block 5 is fixedly set at the river bottom 7, the positioning block 5 has a first connection point, and a second connection point is set on the side of the buoyancy member 1 close to the water surface, and the connection line between the first connection point and the second connection point is parallel to the vertical. Since the buoyancy member 1 rotates relative to the river bank 2, that is, the line connecting the second connection point and the first connection point during the rotation of the buoyancy member 1 will deviate from the vertical direction, the elastic member will be subjected to a certain bending moment at this time, resulting in the risk of bending. When connecting the elastic member, the connection mode between the elastic member and the positioning block 5 and the buoyancy member 1 can be set to be hinged respectively. With this setting, during the rotation of the buoyancy member 1, the line connecting the first connection point and the second connection point can form different angles with the vertical direction as the buoyancy member 1 rotates, that is, the line can be in the same direction of rotation as the second connection point at any time when it rotates, thereby preventing the elastic member from being subjected to a large bending moment during the buoyancy rotation, causing permanent deformation of the elastic member.

[0037] In a preferred embodiment, the elastic member can be configured as a tension spring 4, which is connected to the buoyancy member 1 through a connecting assembly 3. The tension spring 4 can provide a large and stable elastic force for the buoyancy member 1, and is relatively easy to install. For example, the tension spring 4 can be a tension spring 4 with circles at both ends, a first rotating shaft can be extended from the positioning block 5, the circle at one end of the tension spring 4 is sleeved on the first rotating shaft, and a first limiting end can be detachably connected to the end of the first rotating shaft, and the first limiting end can form a limit on the circle to prevent the circle from axially separating from the first rotating shaft; a second rotating shaft can be extended from the connecting assembly 3, the circle at the other end of the tension spring 4 is sleeved on the second rotating shaft, and a second limiting end can be detachably connected to the end of the second rotating shaft, and the second limiting end can form a limit on the circle to prevent the circle from axially separating from the second rotating shaft. During the rotation of the buoyancy member 1, the circles at both ends of the tension spring 4 rotate on the first rotating shaft and the second rotating shaft respectively, and the axis of the tension spring 4 can always coincide with the rotation direction of the second connecting member, so that the tension spring 4 is always in an axially stretched state, thereby avoiding permanent deformation of the tension spring 4.

[0038] In a possible embodiment, the buoyancy member 1 is plate-shaped.

[0039] In the embodiment of the present application, after the buoyancy member 1 is set to a plate shape, one of the plate surfaces of the buoyancy member 1 and the side surface adjacent thereto can be used together as a water retaining working surface, so that the buoyancy member 1 can have a larger contact area with the river water within a limited space, ensuring that a larger buoyancy is applied to the buoyancy member 1, thereby ensuring the follow-up performance of the buoyancy member 1 when the water level changes.

[0040] In a possible embodiment, the buoyancy member 1 is in the shape of a curved plate and its convex surface serves as a water retaining working surface.

[0041] In the embodiment of the present application, the curved plate-shaped buoyancy member 1 can ensure that the buoyancy member 1 has a larger contact area with the river water during the period of rising water level, thereby ensuring that a larger buoyancy is applied to the buoyancy member 1, and further ensuring the follow-up performance of the buoyancy member 1 when the water level changes. In addition, after the convex surface of the buoyancy member 1 is used as a water retaining working surface, the concave surface of the buoyancy member 1 can be used as a place for a few people to move around.

[0042] In a possible embodiment, a waterproof coating is provided on the surface of the buoyancy member 1 .

[0043] In the embodiment of the present application, the provision of the waterproof coating on the buoyancy member 1 can prevent river water from penetrating into the interior of the buoyancy member 1 , thereby ensuring the floating performance of the buoyancy member 1 .

[0044] In a possible embodiment, a waterproof coating is provided on the resetting device and on the structure used for rotational connection between the buoyancy member 1 and the river bank 2 .

[0045] In the embodiment of the present application, a waterproof coating is respectively provided on the reset device and the structure used for rotational connection between the buoyancy member 1 and the river bank 2, which can prevent the river water from corroding the reset device and the structure used for rotational connection between the buoyancy member 1 and the river bank 2, thereby ensuring the effectiveness of the structure.

[0046] In a possible embodiment, the waterproof coating is a Teflon layer.

[0047] In the embodiment of the present application, the Teflon material has good moisture resistance and high and low temperature resistance, can play a good isolation role for river water, and the slidability of the Teflon material can ensure that the structure used for the rotational connection between the buoyancy member 1 and the river bank 2 has good rotational sliding performance, further ensuring the follow-up performance of the buoyancy member 1 during the water level change period.

[0048] In a possible embodiment, the buoyancy member 1 includes an outer shell and a buoyancy filler filled in the outer shell.

[0049] In the embodiment of the present application, the structure of the shell itself can ensure that it has a certain flexibility, so that it is not easy to be broken when the buoyancy member 1 is constructed into a curved plate shape; the shell itself can be made of natural buoyancy materials, for example, the shell can be plastic or a dry wooden body with a waterproof surface. The buoyancy filler in the shell can balance part of the pressure on the shell wall, thereby ensuring the structural safety of the shell, and due to the nature of the buoyancy filler itself, a certain net buoyancy of the buoyancy member 1 can be guaranteed. The buoyancy filler can be solid, gaseous, liquid or a mixture of any two of the foregoing; for example, when the buoyancy filler is solid, it can be configured as foam, dry wood blocks or dry sawdust, etc.; when the buoyancy filler is liquid, it can be configured as ethanol, liquid nitrogen, etc.; when the buoyancy filler is gas, it can be configured as any harmless and non-polluting gas. The buoyancy filler can be filled completely or incompletely in the shell. Taking the problem of deadweight into consideration, the buoyancy filler in the embodiment of the present application is arranged in the shell in an incompletely filled manner. When the buoyancy filler is arranged in the shell in an incompletely filled manner, the buoyancy filler can be prevented from being excessively squeezed, causing the inner wall of the shell to be subjected to greater pressure when the internal space of the shell changes during the deformation process.

[0050] In a possible embodiment, the buoyancy filler is solid.

[0051] In the embodiment of the present application, the solid buoyancy filler has good rigidity. When the shell is deformed under force, the solid buoyancy filler can exert greater pressure on the inner wall of the shell, thereby further balancing the pressure on both sides of the shell wall, thereby ensuring the structural safety of the shell.

[0052] In a possible embodiment, in the vertical direction, when the water level reaches a preset maximum value, there is a distance between the upper end of the buoyancy member 1 and the water surface; when the water level reaches a preset minimum value, there is a distance of not less than 105 cm between the upper end of the buoyancy member 1 and the ground.

[0053] In the embodiment of the present application, when the buoyancy member 1 is in the shape of a curved plate, it actually puts forward requirements on the length and curvature radius of the buoyancy member 1. That is, when the water level reaches the preset maximum value, the upper end of the buoyancy member 1 needs to be higher than the water surface to prevent the river water from overflowing; when the water level reaches the preset minimum value, the upper end of the buoyancy member 1 needs to be at least 105 cm above the ground to effectively protect pedestrians.

[0054] Of course, based on the requirement that the upper end of the buoyancy member 1 needs to be at least 105 cm above the ground, the design parameters of the buoyancy member 1 can be selected according to the following design equation:

[0055]

[0056] Among them, R is the radius of curvature of the buoyancy member 1, in cm; L2 is the arc length on the cross section of the buoyancy member 1, in cm; L1 is the maximum lateral protection distance of the buoyancy member 1, that is, the horizontal distance between the upper end of the buoyancy member 1 and the river bank when the vertical distance between the upper end of the buoyancy member 1 and the ground is equal to 105 cm, in cm. That is, after determining the maximum lateral protection distance of the buoyancy member 1, the above-mentioned design equation can be used to select a reasonable radius of curvature and arc length to ensure that the vertical distance between the upper end of the buoyancy member 1 and the ground is 105 cm when the buoyancy member 1 rotates to the state of the maximum lateral protection distance.

[0057] In the embodiment of the present application, two rotation limits can be set in the rotational connection structure between the buoyancy member 1 and the river bank to prevent the vertical distance between the upper end of the buoyancy member 1 and the ground from being less than 105 cm due to the rotation amplitude of the buoyancy member 1 being too small or too large. The technical means for setting the rotation limit are conventional technical means and will not be elaborated in detail in the embodiment of the present application.

[0058] In a possible embodiment, the buoyancy device further includes a warning device 6, and the warning device 6 is used to be arranged on the river bank 2 to provide visual warning information to pedestrians.

[0059] In the embodiment of the present application, the warning device 6 may include two vertical bars 62 and a horizontal bar 61. The two vertical bars 62 are buried underground respectively, and the ends of the two vertical bars 62 located above the ground are respectively connected to the two ends of the horizontal bar 61. Warning sign information may be set on the horizontal bar 61, and the warning sign information may be text, pictures, light, sound, etc. For example, when the sign information is set as text, it may be "Limited to N people", "Do not approach", "Do not step on gravity", etc. and set on the horizontal bar 61 by spraying. The raw material used for spraying may be a reflective material, so that it can also play an effective warning effect in a weak light environment.

[0060] The height of the warning device 6 is generally set low to prevent it from forming a large obstacle to pedestrians. When the warning sign information is text or pictures, it can only be actively obtained by people lowering their heads, and the effectiveness of its warning effect is relatively limited. Therefore, light signal information and / or sound signal information can be added to the warning sign information. Specifically, there are multiple warning devices 6, and the arrangement direction of all warning devices 6 is parallel to the arrangement direction of the buoyancy member 1. A beam sensor can be configured between adjacent warning devices 6. Multiple infrared sensors can be set on the crossbar 61 of each warning device 6. Multiple infrared sensors in each warning device 6 are connected to a lamp or a buzzer. The beam sensors between adjacent warning devices 6 can be connected to the lamp or buzzer of either of the two. The infrared sensor, the beam sensor and the lamp or buzzer are connected through a trigger circuit. When a pedestrian passes between two adjacent warning devices 6, the human foot triggers the through-beam sensor, and the analog signal generated by the through-beam sensor turns on the lamp or buzzer after passing through the trigger circuit, thereby emitting sound signal information or light signal information; when a pedestrian crosses the warning device 6, the human foot triggers the infrared sensor, and the analog signal generated by the infrared sensor turns on the lamp or buzzer after passing through the trigger circuit, thereby emitting sound signal information or light signal information.
