Description

Technical Field

[0001] The invention belongs to the field of water conservancy engineering and landscape engineering, and particularly relates to an openable and closeable hydrophilic platform and an opening and closing method thereof. Background Art

[0002] In urban river management projects, hydrophilic platforms are generally built to meet landscape needs. However, hydrophilic platforms are interrupted at the outlets of branch ditches and drainage culverts, which destroys the continuity of the hydrophilic platforms and reduces the residents' sightseeing experience. To solve this problem, steps are generally set at the end of the hydrophilic platform. Pedestrians walk to the top of the river bank through the steps and then return to the clear water platform through the steps at the other end, which makes it inconvenient to pass. In addition, a pedestrian bridge is set up to connect. If the pedestrian bridge is too low, it will affect the drainage of the branch ditch or drainage culvert. If the pedestrian bridge is too high, it will lead to a large investment. Summary of the invention

[0003] In view of this, an object of the present invention is to provide an openable and closeable hydrophilic platform and an opening and closing method thereof, so as to overcome the above-mentioned problems or at least partially solve or alleviate the above-mentioned problems.

[0004] The present invention provides an openable and closed hydrophilic platform, comprising:

[0005] Two fixed platforms, whose ends are respectively located on both sides of the drainage culvert outlet, and each of the fixed platforms is provided with a hinged shaft column on the upper part;

[0006] Two movable platforms, one end of each movable platform is a hinged end, and the other end is a movable end, the hinged end of the movable platform is hinged to the hinge shaft column, and the two movable platforms can swing inwards around the hinge shaft column to a closed state and swing outwards to an open state;

[0007] A plurality of support columns, each of which is disposed at the lower part of the movable end of each movable platform, and the lower end of each support column is provided with an underwater roller;

[0008] Wherein, the water bottom below the movable end of the movable platform has a downward slope from outside to inside.

[0009] The present invention also has the following optional features.

[0010] Optionally, it also includes an underwater guide rail, which is arranged under each of the support columns and cooperates with the underwater roller. The underwater guide rail is distributed along the movable range of the underwater roller, and the inner end of the underwater guide rail corresponds to the position of the underwater roller when the movable platform is closed, and the outer end of the underwater guide rail corresponds to the position of the underwater roller when the movable platform is closed.

[0011] Optionally, the movable end of each movable platform is respectively provided with two of the support columns and the underwater rollers thereof, and each of the support columns is respectively close to a corner of the movable end of the movable platform. Correspondingly, an underwater guide rail is provided under each of the support columns and the underwater rollers.

[0012] Optionally, the underwater guide rail protrudes from the underwater surface, and the underwater roller rolls on the upper part of the underwater guide rail.

[0013] Optionally, a hinge hole is provided at the hinge end of the movable platform, and each movable platform is placed on the end of one of the fixed platforms and is sleeved on the hinge shaft column through the hinge hole.

[0014] Optionally, the hinge shaft column is arranged at an inner corner of the end of the fixed platform, and an inner corner of the hinged end of the movable platform is hinged to the hinge shaft column.

[0015] Optionally, a table roller is provided at the bottom of a corner of the outer side of the hinged end of the movable table, and correspondingly, a table guide rail is provided on the fixed platform, the table guide rail matches the table roller, and the table guide rail is distributed along the rolling range of the table roller.

[0016] Optionally, the table guide rail is a groove-type structure, the depth of the groove bottom increases continuously from the outside to the inside on the fixed platform, and the table roller extends into the table guide rail.

[0017] The present invention also proposes a method for opening and closing a hydrophilic platform, which is to respectively arrange hinged shaft columns on fixed platforms on both sides of the drainage culvert outlet, and hinge a movable platform on each hinged shaft column, so that the movable ends of the two movable platforms can swing around the hinged shaft column to a spliced ​​state, and a support column is connected to the lower part of the movable end of each movable platform, and an underwater roller is arranged at the lower end of the support column, and the bottom of the water below the movable end of the movable platform is arranged to be a downward slope from outside to inside; when the water flow in the drainage culvert is small, under the action of gravity, the underwater roller rolls downwardly until the two movable platforms are spliced; when the drainage water flow in the drainage culvert is large, the drainage water flow impacts the support column to move outward, driving the two movable platforms to open outward.

[0018] If the open and close hydrophilic platform of the present invention encounters a small flow of drainage water at the outlet of the drainage culvert, the drainage water can pass through the lower space of the two movable platforms. If a large flow of drainage water is encountered, the movable platform rotates around the hinged shaft column under the impact of the large flow of drainage water to automatically open, thereby reducing the impact on the drainage of the drainage culvert. After the large flow of drainage water in the drainage culvert passes, the movable platform rotates around the hinged shaft column under the action of gravity to automatically splice, thereby realizing the connection between the fixed platforms on both sides. It does not affect the continuity of the hydrophilic platform at ordinary times, and does not affect the drainage when the drainage culvert is drained with a large flow. At the same time, it has a simple structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0023] Example 1

[0024] refer to Figure 1 and Figure 2 An embodiment of the present invention proposes an openable and closed hydrophilic platform, comprising: two fixed platforms 1, two movable platforms 3 and a plurality of support columns 4; the ends of the two fixed platforms 1 are respectively located on both sides of the drainage culvert outlet, and a hinged shaft column 2 is arranged on the upper part of each fixed platform 1; one end of each movable platform 3 is a hinged end, and the other end is a movable end, and the hinged end of the movable platform 3 is hinged to the hinged shaft column 2, and the two movable platforms 3 can swing inward to a closed state and outward to an open state around the hinged shaft column 2; each support column 4 is arranged at the lower part of the movable end of each movable platform 3, and an underwater roller 5 is arranged at the lower end of the support column 4; wherein, the water bottom below the movable end of the movable platform 3 has a downward slope from the outside to the inside.

[0025] When the drainage water flow of the drainage culvert is small, under the action of gravity, the underwater rollers 5 at the lower ends of the support columns 4 at the movable ends of the two movable platforms 3 roll inward along the lower slope, so that the two movable platforms 3 are swung to a closed state respectively. The two movable platforms 3 connect the two fixed platforms 1 to form an integral hydrophilic platform without affecting the passage of pedestrians. The drainage water flow of the drainage culvert flows under the two movable platforms 3; when the water flow in the culvert increases, the water level here also rises, and the thrust of the drainage water flow impacting the support columns 4 pushes the movable ends of the two movable platforms 3 to open outward, away from the drainage culvert. At the same time, the two movable platforms 3 rise along the lower slope, reducing the impact on the drainage of the drainage culvert.

[0026] Example 2

[0027] refer to Figure 1 and Figure 2On the basis of Example 1, it also includes an underwater guide rail 6, which is arranged under each support column 4 and cooperates with the underwater roller 5. The underwater guide rail 6 is distributed along the movable range of the underwater roller 5, and its inner end corresponds to the position of the underwater roller 5 when the movable platform 3 is closed, and its outer end corresponds to the position of the underwater roller 5 when the movable platform 3 is closed.

[0028] The underwater guide rail 6 can be made of metal, laid along the rolling track of the underwater roller 5, matched with the underwater roller 5, and can reduce the friction between the underwater roller 5 and the bottom of the water.

[0029] Example 3

[0030] refer to Figure 2 On the basis of Example 2, the movable end of each movable platform 3 is respectively provided with two support columns 4 and their underwater rollers 5, each support column 4 is respectively close to a corner of the movable end of the movable platform 3, and correspondingly, an underwater guide rail 6 is provided under each support column 4 and underwater roller 5.

[0031] The two support columns 4 are respectively located on the lower surfaces of the two corners of the movable end of each movable platform 3, and can provide stable support for the movable platform 3. An underwater roller 5 is arranged at the lower end of each support column 4. Correspondingly, two underwater guide rails 6 are arranged below the movable end of each movable platform 3, which respectively cooperate with the underwater rollers 5 at the lower ends of the two support columns 4.

[0032] Example 4

[0033] refer to Figure 1 On the basis of Example 3, the underwater guide rail 6 protrudes from the underwater surface, and the underwater roller 5 rolls on the upper part of the underwater guide rail 6.

[0034] In order to prevent underwater mud or other debris from entering between the underwater guide rail 6 and the underwater roller 5 and affecting the swing of the movable platform 3, the underwater guide rail 6 preferably protrudes from the bottom surface and the underwater roller 5 rolls on the underwater guide rail 6.

[0035] Example 5

[0036] refer to Figure 1 On the basis of Example 1, a hinge hole is provided at the hinged end of the movable table 3, and each movable table 3 is placed on the end of a fixed platform 1 and is sleeved on the hinge shaft column 2 through the hinge hole.

[0037] The movable platform 3 cooperates with the hinge shaft 2 through the hinge hole, so that the movable platform 3 can swing around the hinge shaft column 2. At the same time, the hinge shaft column 2 does not prevent the movable platform 3 from changing in height during the swinging process.

[0038] Example 6

[0039] refer to Figure 2 On the basis of Example 5, the hinge shaft column 2 is arranged at an inner corner of the end of the fixed platform 1, and an inner corner of the hinged end of the movable platform 3 is hinged to the hinge shaft column 2.

[0040] In order to ensure that the two movable platform plates 3 do not affect each other when swinging outwards and can be completely closed after swinging inwards, the two movable platform plates 3 need to rotate around an inner corner of their hinged ends. Therefore, it is necessary to hinge an inner corner of the hinged end of the movable platform plate 3 with the hinge shaft column 2.

[0041] Example 7

[0042] refer to Figure 2 On the basis of Example 6, a table roller 7 is provided at the bottom of a corner of the outer side of the hinged end of the movable table plate 3, and correspondingly, a table guide rail 8 is provided on the fixed platform 1, and the table guide rail 8 matches the table roller 7, and the table guide rail 8 is distributed along the rolling range of the table roller 7.

[0043] When the movable table 3 rotates around the hinge shaft column 2, in order to prevent friction and wear between the other corner of the movable table 3 resting on the fixed platform 1 and the fixed platform 1, it is necessary to set a table roller 7 at the lower part of the part where the movable table 3 rests on the fixed platform 1, and set a table guide rail 8 on the fixed platform 1. The table guide rail 8 is set along the track of the table roller 7. The cooperation of the table roller 7 and the table guide rail 8 can greatly reduce friction and wear.

[0044] Example 8

[0045] refer to Figure 2 On the basis of Example 6, the table guide rail 8 is a groove structure, the depth of the groove bottom is continuously deepened from the inside to the outside on the fixed platform 1, and the table roller 7 extends into the table guide rail 8.

[0046] When the movable platform 3 rotates, the movable platform 3 will gradually rise due to the underwater rollers 5 moving outward along the underwater slope and the underwater guide rails 6. Therefore, the table guide rails 8 on the fixed platform 1 should be set as a groove structure, and its trajectory is consistent with the movement trajectory of the table rollers 7. It gradually deepens from the inner end to the outer end, that is, it gradually becomes shallower from the outer end to the inner end, which just adapts to the situation that the movable platform 3 continues to rise as a whole when it swings outward.

[0047] Example 9

[0048] An embodiment of the present invention proposes a method for opening and closing a hydrophilic platform, wherein hinged shaft columns 2 are respectively arranged on fixed platforms 1 on both sides of the drainage culvert outlet, and a movable platform 3 is respectively hinged on each hinged shaft column 2, so that the movable ends of the two movable platform plates 3 can swing around the hinged shaft column 2 to a spliced ​​state, and a support column 4 is connected to the lower part of the movable end of each movable platform plate 3, and underwater rollers 5 are arranged at the lower end of the support column 4, and the bottom of the water below the movable end of the movable platform plate 3 is arranged as a downward slope from outside to inside; when the water flow in the drainage culvert is small, under the action of gravity, the underwater rollers 5 roll downwardly on the slope until the two movable platform plates 3 are spliced; when the drainage water flow in the drainage culvert is large, the drainage water flow impacts the support column 4 to move outward, driving the two movable platform plates 3 to open outward.

[0049] The sum of the lengths of the two movable platform plates 3 from the hinge point to the swing end should be exactly equal to the distance between the two hinge shaft columns 2. The support column 4 is preferably a hollow pipe column with a larger diameter so that the drainage water flow has a greater impact force on it.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
