Description

Technical Field

[0001] The invention belongs to the fields of water conservancy engineering and landscape engineering, and particularly relates to a sliding 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 a sliding hydrophilic platform and an opening and closing method thereof, so as to overcome the above problems or at least partially solve or alleviate the above problems.

[0004] The present invention provides a sliding hydrophilic platform, comprising:

[0005] Two fixed platforms are respectively located on both sides of the drainage culvert outlet, and a guide groove is transversely arranged on the upper part of each fixed platform;

[0006] Two movable platforms, the rear end of each movable platform is placed on the fixed platform and slidably cooperates with the guide groove, a support column is connected below the front end of the movable platform, and an underwater roller is arranged at the lower end of the support column;

[0007] An inclined plate, the inclined plate is fixed on each of the support columns, and the surface of the inclined plate is biased toward the front end of the movable platform and the outlet direction of the drainage culvert;

[0008] The underwater bottom below the front end of each movable platform has a first inclined surface extending forward and tilted downward, and the underwater roller rolls along the first inclined surface.

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

[0010] Optionally, it also includes an underwater guide rail, which is arranged below each of the support columns and cooperates with the underwater rollers. The underwater guide rails are distributed along the movable range of the underwater rollers, and the first inclined surface is arranged on the upper part of the underwater guide rails.

[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 distributed on both sides of the front end of the movable platform and staggered on both sides 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 a groove is provided on the wheel surface of the underwater roller, and the underwater roller rolls on the first inclined surface on the underwater guide rail through the groove.

[0013] Optionally, a table roller is provided at the lower part of the rear end of the movable table, and the table roller cooperates with the guide groove.

[0014] Optionally, a second inclined surface is provided at the bottom of the guide groove, and the slope of the second inclined surface is the same as the slope of the first inclined surface corresponding to the movable platform on the same side.

[0015] Optionally, the guide grooves on each of the fixed platforms are arranged in pairs, and correspondingly, the table rollers are arranged in pairs at the lower part of the rear end of the movable table.

[0016] The present invention also proposes a method for opening and closing a hydrophilic platform, wherein guide grooves are respectively arranged transversely on the fixed platforms on both sides of the drainage culvert outlet, and a pair of movable platforms are arranged between the two fixed platforms, so that the front ends of the two movable platforms are opposite to each other, and the rear ends are respectively slidably matched with the guide grooves on one of the fixed platforms, a support column is connected to the lower part of the front end of each movable platform, an underwater roller is arranged at the lower end of the support column, an inclined plate is fixed on each support column, and the surface of the inclined plate is biased toward the front end of the movable platform and the outlet direction of the drainage culvert, and a first inclined surface extending forward and inclined downward is arranged on the bottom below the front end of each movable platform; when the water flow in the drainage culvert is small, under the action of gravity, the underwater roller rolls downward along the first slope until the two movable platforms are spliced ​​together; when the drainage water flow in the drainage culvert is large, the drainage water flow impacts the inclined plate on the support column, pushes the inclined plate and the support column, and drives the two movable platforms to slide toward their rear ends respectively, so that the two movable platforms are separated.

[0017] If the sliding 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 support column and the inclined plate of the movable platform will push the movable platform to slide to the rear end under the impact of the large flow of drainage water, so that the front ends of the two movable platforms are separated, 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 slides toward the front end along the first inclined surface through the underwater roller under the action of gravity until it is automatically spliced, 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 , Figure 2 and Figure 3 An embodiment of the present invention proposes a sliding hydrophilic platform, comprising: two fixed platforms 1, two movable platforms 3 and an inclined plate 6; the two fixed platforms 1 are respectively located on both sides of the drainage culvert outlet, and a guide groove 2 is transversely arranged on the upper part of each fixed platform 1; the rear end of each movable platform 3 is placed on the fixed platform 1 and slidably cooperates with the guide groove 2, and a support column 4 is connected below the front end of the movable platform 3, and an underwater roller 5 is arranged at the lower end of the support column 4; the inclined plate 6 is fixed on each support column 4, and the surface of the inclined plate 6 is biased toward the front end of the movable platform 3 and the direction of the drainage culvert outlet; wherein, the bottom of the water below the front end of each movable platform 3 has a first inclined surface extending forward and inclined downward, and the underwater roller 5 rolls along the first inclined surface.

[0025] When the drainage water flow of the drainage culvert is small, under the action of gravity, the underwater roller 5 at the lower end of the support column 4 connected to the lower part of the front end of the two movable platforms 3 rolls forward along the first inclined plane, so that the two movable platforms 3 slide forward respectively until the front ends of the two movable platforms 3 touch each other, so that the two movable platforms 3 connect the two fixed platforms 1 to form an integral hydrophilic platform, which does not affect the passage of pedestrians, and the drainage water flow of the drainage culvert flows under the two movable platforms 3; when the drainage water flow of the drainage culvert increases, the water level here also rises, and the thrust of the drainage water flow impacting the support column 4 and the inclined plate 6 pushes the two movable platforms 3 to slide toward the rear end along the guide groove 2, so that the two movable platforms 3 are separated and away from the drainage culvert, reducing the impact on the drainage of the drainage culvert.

[0026] Example 2

[0027] refer to Figure 1 , Figure 2 and Figure 3 On the basis of Example 1, it also includes an underwater guide rail 7, which is arranged below each support column 4 and cooperates with the underwater roller 5. The underwater guide rail 7 is distributed along the movable range of the underwater roller 5, and the first inclined surface is arranged on the upper part of the underwater guide rail 7.

[0028] The underwater guide rail 7 can be made of metal and laid along the rolling track of the underwater roller 5, matching the underwater roller 5, and reducing the friction of the underwater roller 5. The first inclined surface is processed on the upper part of the underwater guide rail 7 to facilitate the control of the inclination of the first inclined surface. When laying the underwater guide rail 7, it is sufficient to ensure that the bottom surface is level.

[0029] Example 3

[0030] refer to Figure 1 , Figure 2 and Figure 3 On the basis of Example 2, two support columns 4 and underwater rollers 5 are respectively provided at the movable end of each movable platform 3, and each support column 4 is respectively distributed on both sides of the front end of the movable platform 3 and staggered on both sides of the movable platform 3. Correspondingly, an underwater guide rail 7 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 both sides of the front end of each movable platform 3, which 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 7 are arranged below the front end of each movable platform 3, which respectively cooperate with the underwater rollers 5 at the lower ends of the two support columns 4; in order to enable the inclined plate 6 on each support column 4 to be impacted by the drainage water flow of the drainage culvert to generate thrust, it is necessary to stagger the two support columns 4 on both sides of each movable platform 3.

[0032] Example 4

[0033] refer to Figure 1 On the basis of Example 3, the underwater guide rail 7 protrudes from the underwater surface, and a groove is provided on the wheel surface of the underwater roller 5, and the underwater roller 5 rolls on the first inclined surface on the underwater guide rail 7 through the groove.

[0034] In order to prevent underwater mud or other debris from entering between the underwater guide rail 7 and the underwater roller 5 and affecting the sliding of the movable platform 3, the underwater guide rail 7 is preferably protruding from the underwater surface, and the underwater roller 5 rolls on the underwater guide rail 7 through the groove, which can prevent the underwater roller 5 from being separated from the underwater guide rail 7 due to lateral impact of the drainage water flow of the drainage culvert.

[0035] Example 5

[0036] refer to Figure 1 , Figure 2 and Figure 3 On the basis of Example 1, a table roller 8 is provided at the lower part of the rear end of the movable table plate 3, and the table roller 8 cooperates with the guide groove 2.

[0037] The table roller 8 extends into the guide groove 2 and rolls, which can reduce the friction between the movable table plate 3 and the fixed platform 1. At the same time, the guide groove 2 can also play a sliding guiding role for the table roller 8 and the movable table plate 3.

[0038] Example 6

[0039] refer to Figure 1 On the basis of Embodiment 5, a second inclined surface is provided at the bottom of the guide groove 2, and the second inclined surface has the same slope as the first inclined surface corresponding to the movable table 3 on the same side.

[0040] When the underwater roller 5 rolls along the first inclined surface on the underwater guide rail 7, the front end of the movable platform 3 will rise or fall with the first inclined surface. In order to keep the movable platform 3 level, a second inclined surface is set at the bottom of the guide groove 2, so that the slope of the second inclined surface is the same as the slope of the first inclined surface corresponding to the movable platform 3 on the same side. When the table roller 8 at the rear end of the movable platform 3 rolls along the second inclined surface at the bottom of the guide groove 2, the rear end of the movable platform 3 will rise or fall with the second inclined surface, so that the front and rear ends of the movable platform 3 are the same height, and the whole is always in a horizontal state.

[0041] Example 7

[0042] refer to Figure 2 and Figure 3 On the basis of Example 6, the guide grooves 2 on each fixed platform 1 are arranged in pairs, and correspondingly, the table rollers 8 are arranged in pairs at the lower part of the rear end of the movable table 3.

[0043] The table rollers 8 at the lower rear end of the movable table 3 are arranged in pairs and cooperate with the guide grooves 2 arranged in pairs on the fixed platform 1, so that the rear end of the movable table 3 is stably supported on the fixed platform 1.

[0044] Example 8

[0045] The embodiment of the present invention proposes a method for opening and closing a hydrophilic platform, wherein guide grooves 2 are respectively arranged transversely on the fixed platforms 1 on both sides of the outlet of the drainage culvert, and a pair of movable platforms 3 are arranged between the two fixed platforms 1, so that the front ends of the two movable platforms 3 are opposite to each other, and the rear ends are respectively slidably matched with the guide grooves 2 on one of the fixed platforms 1, and the lower part of the front end of each movable platform 3 is connected to the support column 4, and the underwater roller 5 is arranged at the lower end of the support column 4, and an inclined plate 6 is fixed on each support column 4, and the surface of the inclined plate 6 is biased toward the front end of the movable platform 3 and the outlet direction of the drainage culvert, and a first inclined surface extending forward and inclined downward is arranged on the bottom below the front end of each movable platform 3; when the water flow in the drainage culvert is small, under the action of gravity, the underwater roller 5 rolls downward along the first slope until the two movable platforms 3 are spliced; when the drainage water flow in the drainage culvert is large, the drainage water flow impacts the inclined plate 6 on the support column 4, pushes the inclined plate 6 and the support column 4, and drives the two movable platforms 3 to slide toward their rear ends respectively, so that the two movable platforms 3 are separated.

[0046] The inclined surface of the inclined plate 6 is 45 degrees to the drainage flow direction of the drainage culvert. When the drainage flow is large, the horizontal component of the thrust of the drainage flow on the inclined plate 6 pushes the two movable platforms 3 to their rear ends respectively, so that the two movable platforms 3 slide and open to the rear ends along the guide groove 2. When the drainage flow is small, the horizontal component of the gravity of the movable platform 3, the support column 4, the inclined plate 6 and the underwater roller 3 on the first inclined surface causes the underwater roller 3 to slide forward along the first inclined surface until the front ends of the two movable platforms 3 contact and close.

[0047] 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. The components and structures not described in detail in this embodiment are well-known components and common structures or common means in the industry, and are not described here one by one.
