Description

Technical Field

[0001] The invention belongs to the technical field of landscape floating bridges, and in particular relates to an ecological landscape floating bridge applied to a river channel in a scenic area and an installation method thereof. Background Art

[0002] Floating bridges can rise and fall with the water level. Compared with other bridges, they are generally simple to build and low-cost. Aquatic plants can be planted on the floating bridges, which is conducive to the construction of ecological landscapes and water travel. They are mainly composed of floating block units, connecting structures between floating block units, flexible railings, and fixing systems. Ecological plants are set on the outside of the railings. The fixing system is generally divided into anchor rope fixation and column fixation.

[0003] However, for the river channel in the scenic area, due to the impact of water flow on the floating blocks under the influence of mountain torrents in the rainy season, the column fixing method bears a large radial load, while the anchor rope fixing method leads the anchor rope into the river channel, which affects the beauty of the river channel in the scenic area when the water quality is clear during the dry season and is not conducive to the construction of the ecological landscape. Summary of the invention

[0004] The purpose of the present invention is to provide an ecological landscape floating bridge applied to a river in a scenic area and an installation method thereof in order to solve the above-mentioned problem.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] An ecological landscape floating bridge applied to a river in a scenic area, comprising

[0007] A floating bridge assembly, comprising a plurality of floating block units and columns fixed on the riverbed, wherein a through groove is arranged on the surface of some of the floating block units, the columns pass through the through groove and the floating block units have a movable space in the direction of water flow;

[0008] An anchor rope mechanism, comprising a reel disposed below the partial floating block unit, an anchor rope with one end wound around the reel and the other end fixed to the riverbed, the shaft of the reel being transmission-connected with a clutch;

[0009] The driving component is set on the column as the floating block unit rises and falls, and includes a paddle blade, which is connected to the clutch through a deceleration structure. The clutch is pressed when the floating bridge assembly is impacted by the water flow, so that the paddle blade drives the winding wheel to tighten the anchor rope.

[0010] As a further optimization scheme of the present invention, the shaft of the winding wheel is provided with a torsion spring, and the torsion spring is used to rotate the winding wheel in the unwinding direction. This scheme rotates the winding wheel in the unwinding direction by arranging the torsion spring. In the dry season, the anchor rope can be automatically released, so that the anchor rope relaxes and falls to the bottom of the water, and is hidden by the water plants and stones on the bottom of the water, which is beneficial to aesthetics.

[0011] As a further optimization scheme of the present invention, the clutch includes a clutch seat and a clutch plate, the clutch seat is rotationally connected to the extension part arranged under the floating block unit, and the winding wheel is transmission connected to the clutch seat. In this scheme, the winding wheel is driven to be wound through the driving component by setting a clutch, and the clutch seat and the clutch plate can be selected as needed to meet the torque requirements. When the floating block unit is subjected to a large impact of the water flow, the clutch seat is pressed toward the clutch plate to generate pressure, so that when the water flow drives the blade to rotate, the clutch plate can drive the winding wheel to wind up the anchor rope, so that the anchor rope is subjected to force. When it is wound to a certain extent, the pressure between the clutch seat and the clutch plate is not enough to make the clutch plate drive the clutch seat to rotate, which means that the anchor rope is tightened and bears part of the impact force of the water flow.

[0012] As a further optimization scheme of the present invention, the driving component also includes a housing, and the reduction structure includes a worm wheel and a worm arranged in the housing, the worm is coaxially connected to the blade, and the worm wheel is connected to the clutch plate through a transmission part. This scheme specifically proposes a reduction structure, which increases the torque by reducing the speed of the worm wheel. Specifically, the blade drives the worm wheel to rotate slowly through the worm, and the worm wheel drives the winding wheel to rotate through the clutch.

[0013] As a further optimization scheme of the present invention, the transmission connection structure between the winding wheel and the clutch seat includes a first bevel gear and a second bevel gear, and the transmission part between the clutch plate and the worm gear includes a first transmission part and a second transmission part. In this scheme, the transmission connection structure and the transmission part both need to involve vertical transmission, which can be achieved through bevel gears or universal joints.

[0014] As a further optimization scheme of the present invention, a sliding assembly is provided on the column, and the box body is lifted and lowered along the column through the sliding assembly, wherein the sliding assembly includes a slide cylinder mounted on the column, and the slide cylinder is lifted and lowered with the floating block unit. The box body is connected to the slide cylinder for transverse sliding through a transverse slide groove, and a limiting groove is provided on the inner wall of the slide groove, and a limiting strip corresponding to the limiting groove is provided on the outside of the box body. By providing the sliding assembly, it is convenient to be driven by the floating block unit to lift and lower along the column, and this scheme realizes the transverse sliding of the box body along the slide cylinder through the limiting strip and the limiting groove.

[0015] As a further optimization scheme of the present invention, a limit arm is provided on the surface of the slide cylinder, and a limit tooth corresponding to the limit arm is provided on the worm, and the limit arm engages / disengages with the limit tooth when the box slides laterally, wherein a spring is provided in the slide groove, for pushing the box to slide in the direction of engagement between the limit tooth and the limit arm, so as to limit the rotation of the worm. Since the clutch seat and the clutch plate are always in contact and have a certain pressure, when the winding wheel is tightened, the paddle continues to drive the clutch plate to rotate, and the friction between the clutch seat and the clutch plate is relatively large. In order to solve this problem, a limit arm is provided in this scheme to limit the rotation of the worm when the winding wheel is wound into place.

[0016] As a further optimization scheme of the present invention, an angled block is provided at the bottom of the column, and an angled groove is provided on the surface of the box body. The angled groove is used to contact the angled block when the box body descends, so as to drive the box body to move in the direction of the compression spring. The function of this scheme is to separate the clutch plate from the clutch seat when the water level is low. Water will still flow when the water level is low, and the impact force is small. It is close to the bottom of the column, so that the column can bear it. The power connection between the clutch plate and the clutch seat can be released to relax the reel, which is convenient for hiding the anchor rope.

[0017] As a further optimization scheme of the present invention, the top of the slide is provided with an outer flange, and the bottom of the floating block unit is provided with a limiting portion corresponding to the outer flange, which is used to drive the slide to rise and fall through the outer flange. This scheme is used to drive the slide to rise and fall specifically through the floating block unit.

[0018] On the other hand, the present invention also proposes an installation method of an ecological landscape floating bridge applied to a scenic river, comprising the following steps:

[0019] S1: Install the anchor rope mechanism and driving components under the floating block unit with the through groove;

[0020] S2: Fixing a column on the riverbed, placing a floating block unit with a through groove into the column, sliding a driving component on the column, and leading the anchor rope of the anchor rope mechanism to the upstream direction of the river channel and anchoring it to the riverbed;

[0021] S3: Connect other free floating block units with the floating block units with through grooves, and install side enclosures on the floating block units.

[0022] The beneficial effects of the present invention are:

[0023] The present invention fixes the floating bridge assembly by arranging columns and anchor ropes. When the water level is low, the columns are used to fix the floating bridge assembly, and the anchor ropes are hidden on the riverbed. During rainy seasons and mountain torrents, a clutch, an anchor rope mechanism, and a driving component are arranged. When the impact of the water flow is large, the clutch is connected to the transmission through pressure, and the winding wheel is wound up, so that the anchor rope is stretched straight and stressed, and the impact of the water flow is withstood to protect the columns.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Example 1

[0035] like Figure 1-8 As shown, an ecological landscape floating bridge applied to a river in a scenic area comprises

[0036] A floating bridge assembly 1 includes a plurality of floating block units 11 and columns 13 fixed on a riverbed, wherein a through groove 12 is provided on the surface of some of the floating block units 11, the columns 13 pass through the through groove 12, and the floating block units 11 have a movable space in the direction of water flow;

[0037] The anchor rope mechanism 2 includes a reel 21 disposed below a portion of the floating block unit 11, an anchor rope 22 with one end wound around the reel 21 and the other end fixed to the riverbed, and a clutch is connected to the shaft of the reel 21;

[0038] The driving component 4 is set on the column 13 as the floating block unit 11 rises and falls, and includes a paddle 49. The paddle 49 is connected to the clutch through a deceleration structure. The clutch is pressed when the floating bridge assembly 1 is impacted by the water flow, so that the paddle 49 drives the winding wheel 21 to tighten the anchor rope 22.

[0039] This solution fixes the floating bridge assembly 1 by setting up columns 13 and cooperating with anchor ropes 22. When the water level is low, it is fixed by the columns 13, and the anchor rope 22 is hidden on the riverbed. During rainy season floods, by setting up a clutch, an anchor rope mechanism 2 and a driving component 4, when the impact of the water flow is large, the clutch is connected to the transmission through pressure, and the winding wheel 21 is wound up, so that the anchor rope 22 is straightened and stressed, withstands the impact of the water flow, and protects the columns 13.

[0040] The shaft of the winding wheel 21 is provided with a torsion spring, which is used to rotate the winding wheel 21 in the unwinding direction. In this scheme, the winding wheel 21 is rotated in the unwinding direction by providing a torsion spring. In the dry season, the anchor rope 22 can be automatically released when the clutch is not engaged, so that the anchor rope 22 is relaxed and falls to the bottom of the water, and is hidden by the water plants and stones on the bottom of the water, which is beneficial to the appearance.

[0041] The clutch includes a clutch seat 25 and a clutch plate 26. The clutch seat 25 is rotationally connected to an extension portion arranged below the floating block unit 11, and the winding wheel 21 is transmission-connected to the clutch seat 25. In this scheme, the winding wheel 21 is driven to be wound through the driving component 4 by setting a clutch. The clutch seat 25 and the clutch plate 26 can be selected as needed to meet the torque. When the floating block unit 11 is subjected to a large impact of the water flow, the clutch seat 25 is pressed toward the clutch plate 26 to generate pressure, so that when the water flow drives the paddle 49 to rotate, the winding wheel 21 can be driven by the clutch plate 26 to wind up the anchor rope 22, so that the anchor rope 22 is tightened and stressed. When the winding is reeled to a certain extent, the pressure between the clutch seat 25 and the clutch plate 26 is not enough to make the clutch plate 26 drive the clutch seat 25 to rotate, which means that the anchor rope 22 is tightened to withstand part of the water flow impact force.

[0042] The driving component 4 also includes a housing 41, and the reduction structure includes a worm wheel 47 and a worm 48 arranged in the housing 41. The worm 48 is coaxially connected to the paddle 49, and the worm wheel 47 is connected to the clutch plate 26 through a transmission part. This scheme specifically proposes a reduction structure, which increases the torque by reducing the speed of the worm wheel 47 and the worm 48. Specifically, the paddle 49 drives the worm wheel 47 to rotate slowly through the worm 48, and the worm wheel 47 drives the winding wheel 21 to rotate through the clutch.

[0043] The transmission connection structure between the winding wheel 21 and the clutch seat 25 includes a first bevel gear 23 and a second bevel gear 24, and the transmission part between the clutch plate 26 and the worm gear 47 includes a first transmission part 45 and a second transmission part 46. In this scheme, the transmission connection structure and the transmission part both need to involve vertical transmission, which can be achieved through bevel gears or universal joints.

[0044] A sliding assembly 3 is provided on the column 13, and the box body 41 is lifted and lowered along the column 13 through the sliding assembly 3, wherein the sliding assembly 3 includes a slide 31 sleeved on the column 13, and the slide 31 is lifted and lowered with the floating block unit 11. The box body 41 is connected to the slide 31 for transverse sliding through a transverse slide groove 42, and a limiting groove 44 is provided on the inner wall of the slide groove 42, and a limiting strip 33 corresponding to the limiting groove 44 is provided on the outside of the box body 41. By setting the sliding assembly 3, it is convenient for the box body 41 to be driven by the floating block unit 11 to lift and lower along the column 13, and this scheme realizes the transverse sliding of the box body 41 along the slide 31 through the limiting strip 33 and the limiting groove 44.

[0045] A limit arm 34 is provided on the surface of the slide 31, and a limit tooth 410 corresponding to the limit arm 34 is provided on the worm 48. The limit arm 34 engages / disengages with the limit tooth 410 when the box 41 slides horizontally, wherein a spring 43 is provided in the slide groove 42, which is used to push the box 41 to slide in the direction of engagement between the limit tooth 410 and the limit arm 34, so as to limit the rotation of the worm 48. An angled block 14 is provided at the bottom of the column 13, and an oblique groove 411 is provided on the surface of the box 41, which is used to contact the angled block 14 when the box 41 descends, so as to drive the box 41 to move in the direction of the compression spring 43.

[0046] Since the clutch seat 25 is always in contact with the clutch plate 26 and has a certain pressure, when the winding wheel 21 is tightened, the paddle 49 continues to drive the clutch plate 26 to rotate, and the dynamic friction between the clutch seat 25 and the clutch plate 26 is relatively large. In order to solve this wear problem, the present solution provides a limit arm 34 to limit the rotation of the worm 48 when the winding wheel 21 is wound into place.

[0047] An outer flange 32 is provided on the top of the slide 31, and a limit portion 15 corresponding to the outer flange 32 is provided on the bottom of the float unit 11, which is used to drive the slide 31 to rise and fall through the outer flange 32. The effect of this scheme is to completely separate the clutch plate 25 from the clutch seat 26 when the water level is low. Since water still flows at a low water level, the impact force is small and it is close to the bottom of the column 13, so the column 13 can withstand it. Releasing the power connection between the clutch plate 25 and the clutch seat 26 can relax the winding wheel 21, which is convenient for hiding the anchor rope 22.

[0048] The specific implementation method is as follows: when the water level rises, the impact force of the water flow direction on the floating block unit 11 gradually increases, and the pressure on the column 13 becomes larger. The clutch in this direction first contacts and is pressed to achieve the driving function, but the spring 43 is not compressed at this time, and the limit arm 34 is engaged with the limit tooth 410 to prevent the worm 48 from rotating. Then, when the impact force of the water flow continues to increase, the force pushes the clutch plate 26 through the clutch seat 25 and then pushes the box 41 to compress the spring 43 (using a strong spring), such as Figure 5 and Figure 8 As shown, the limiting tooth 410 moves forward and escapes from the restriction of the limiting arm 34. At this time, the paddle 49 rotates under the impact of the water flow, driving the worm 48 to rotate, and then driving the clutch transmission through the worm gear 47, and the winding wheel 21 winds up the anchor rope 22. When the anchor rope 22 is tightened and stressed, it continues to be wound to overcome part of the impact force of the water flow, so that the spring 43 is reset a small amount. During the small amount of reset, the limiting arm 34 re-limits the limiting tooth 410 to prevent the worm 48 from rotating.

[0049] When the water level continues to rise, the floating block unit 11 rises, resulting in the anchor rope 22 being insufficient in length and requiring a small amount of unwinding. The principle of a small amount of unwinding is that due to the floating block unit 11 floating up, the tension of the anchor rope 22 causes the floating block unit 11 to deviate slightly toward the anchor rope 2, further reducing the contact pressure between the clutch seat 25 and the clutch plate 26, causing the clutch seat 25 and the clutch plate 26 to slip, so that the reel 21 can be unwound freely for a short time. After a small amount of unwinding, the clutch seat 25 and the clutch plate 26 are pressed again, achieving the purpose of adaptive length as the water level rises.

[0050] When the water level drops, the anchor rope 22 loosens a little as the floating block unit 11 drops, and the floating block unit 11 pushes the box body 41 again to overcome the lateral sliding of the spring 43, thereby causing the limit arm 34 to release the worm 48, and the worm 48 rotates to continue tightening the reel 21;

[0051] When the water level drops to the dry season, the floating block unit 11 is close to the bottom of the column 13, and the water flow is not urgent, so it can be fixed by the column 13 to hide the anchor rope 22. Specifically, the slide cylinder 31 falls on the base below the column 13, and the bevel block 14 enters the inclined groove 411 and is inserted between the box body 41 and the clutch seat 25, so that the box body 41 drives the clutch plate 26 to disengage from the clutch seat 25, so that the winding wheel 21 can unwind freely, and the anchor rope 22 is unwound to sink to the bottom of the riverbed.

[0052] On the other hand, the present invention also proposes an installation method of an ecological landscape floating bridge applied to a scenic river, comprising the following steps:

[0053] S1: Install the anchor rope mechanism 2 and the driving component 4 below the floating block unit 11 with the through slot 12;

[0054] S2: Fix the column 13 on the riverbed, put the floating block unit 11 with the through slot 12 into the column 13, slide the driving component 4 on the column 13, and lead the anchor rope 22 of the anchor rope mechanism 2 to the upstream direction of the river channel and anchor it to the riverbed;

[0055] S3: Connect other free floating block units 11 with the floating block units 11 with through grooves 12 , and install side enclosures on the floating block units 11 .

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
