A water stepping stone with an aeration and oxygenation structure

Abstract

The present invention relates to a water stepping stone with an aeration and oxygenation structure, including a base pile. The base pile is formed by combining two cylindrical bases side by side. Two sets of pressurization components and two sets of oxygenation components are arranged inside the base pile. The pressurization component includes a hydraulic cavity arranged in the base pile, a pressing plate adapted to the hydraulic cavity, and a transmission channel communicated with the bottom of the hydraulic cavity. The pressurization component is used to drive the oxygenation component to aerate the water. By setting a pressing plate with a relatively large area as the pressurization component, the water in the hydraulic cavity can flow slightly when the stepping stone moves downward slightly, forming a driving force, thereby reducing the downward movement amplitude of the stepping stone component and improving safety. Two spaced stepping stone components and a hinge rod are used to form a lever structure. With the spaced stepping stone components as the fulcrums, the force on the pressing plate is located at the center of the pressing plate, reducing the probability of wear on the edge of the pressing plate and improving its service life.

Description

Technical Field

[0001] The invention belongs to the technical field of stepping stones in water, and particularly relates to a stepping stone in water with an aeration and oxygenation structure. Background Technique

[0002] A stepping stone is a type of stepping stone set on water, which means that stones are arranged at a certain interval in shallow water, slightly exposed above the water surface, and it is an aesthetic landscape decoration and a water passage.

[0003] The existing stepping stones are composed of cast-in-place foundation piles and stepping stones, and their structures and functions are relatively single. Chinese invention patent CN108341549A discloses an ecological restoration system of coupling aeration of stepping stones and overflow weirs, which uses stepping stones for aeration in water and pressurizes and aerates the water when being stepped on by people. The stepping stones have the following disadvantages: the stepping stones are generally cuboids or cubes, and it is very difficult for the stepping position to be at the center of the stepping stone. When it slides up and down, the stress point of the stepping stone is not at the center, resulting in serious wear of the side wall seals; the sliding amplitude of the stepping stone up and down is relatively large, which is difficult for pedestrians and has the risk of falling into the water. Summary of the Invention

[0004] The purpose of the present invention is to provide a stepping stone in water with an aeration and oxygenation structure to solve the above problems.

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

[0006] A stepping stone in water with an aeration and oxygenation structure includes a foundation pile, the foundation pile is formed by juxtaposing two cylindrical bases, two sets of pressurization components and two sets of oxygenation components are arranged inside the foundation pile, the pressurization component includes a hydraulic cavity arranged in the foundation pile, a pressing plate adapted to the hydraulic cavity, and a transmission channel communicated with the bottom of the hydraulic cavity, and the pressurization component is used to drive the oxygenation component to aerate the water;

[0007] Four stepping stone components are arranged at the upper end of the foundation pile. The stepping stone component includes a sliding base spanning above the foundation pile, a sliding block slidably connected to the sliding base, a stepping stone main body arranged above the sliding block, a return spring arranged below the sliding block for pushing the sliding block upward, a hinge rod is jointly hinged at the bottom ends of a pair of spaced sliding blocks, a connecting rod is hinged in the middle section of the hinge rod, the connecting rod is directly above the center of the pressing plate, and the connecting rod is hinged to the top end of the pressing plate.

[0008] As a further optimized solution of the present invention, a limiting strip is arranged at the upper edge of the pressing plate, and a limiting convex strip is slidably arranged on the inner wall of the foundation pile and mutually slidable with the limiting strip. Since the aspect ratio of the pressing plate is very small, during the downward pressing process, the pressing plate is prone to tilt under force, causing wear of the side wall sealing structure. Therefore, the limiting strip is arranged to limit the vertical downward sliding of the pressing plate.

[0009] As a further optimization scheme of the present invention, a sealing ring is provided on the circumferential surface of the pressure plate to increase the sealing performance between the pressure plate and the side wall of the hydraulic chamber, so that the hydraulic pressure can be better transmitted to the aeration assembly during the downward pressing of the pressure plate.

[0010] As a further optimization scheme of the present invention, the length and width of the sliding block are smaller than the stepping body, the return springs are distributed at the four corners below the sliding block, the sliding block is in the shape of a boss, and the bottom end of the sliding base is provided with a bottom groove for the hinge rod to extend downward. In order to increase the aesthetics, the width of the sliding block is smaller than the stepping body, so that the appearance is simple and easy to hide. The shape of the sliding block limits the range of sliding up and down of the stepping body.

[0011] As a further optimization scheme of the present invention, the aeration component includes a gas booster chamber connected to the transmission channel, and the gas booster chamber is provided with a piston at one end close to the transmission channel, and a one-way air inlet and a one-way aeration port are provided at the other end. The one-way air inlet is extended by a pipeline to communicate with the atmosphere and is provided with a one-way valve for air intake, and the one-way aeration port is connected to the aeration plate and is provided with a one-way valve for outward aeration. The aeration component is transmitted through a hydraulic cavity with a larger area to a piston with a larger aspect ratio. The piston is not prone to edge leakage, and the stroke amplitude of the pressure plate is small. However, when transmitted to the piston, the piston has a larger movement amplitude, which is used for air intake and aeration. The piston resets, and the sliding block is reset by the reset spring, thereby driving the pressure plate to reset, and the negative pressure of the hydraulic cavity sucks the piston back to its original position.

[0012] As a further optimization scheme of the present invention, a first spring is provided inside the gas boost chamber for pushing the piston to move toward one end of the transmission channel, and a one-way water inlet valve is provided on the surface of the pressure plate for letting water into the lower part of the pressure plate. After repeated use and wear, a small amount of water leakage may occur at the edge of the pressure plate. Although a small amount of water leakage has little effect on the downward pressure of the pressure plate, long-term water leakage will cause the water volume in the hydraulic chamber to gradually decrease, and the pushing effect on the piston will be reduced. For this reason, a one-way water inlet valve is provided on the surface of the pressure plate, so that water is replenished to the lower part of the pressure plate when the pressure plate moves up, and the reset of the piston is achieved by the first spring. Under this scheme, by optimizing the reset process of the piston and the pressure plate, even if a small amount of water leakage occurs at the edge of the pressure plate, its effect on the increase in hydraulic chamber pressure can be ignored.

[0013] As a further optimization scheme of the present invention, both ends of the hinged rod are bent upward for hinge connection with the sliding block, and the tops of the two cylindrical bases are interconnected for the passage of the hinged rod. This scheme is a structural optimization made to eliminate structural interference.

[0014] The beneficial effects of the present invention are:

[0015] The present invention sets a pressing plate with a relatively large area as a pressurizing component, so that the water in the hydraulic cavity can flow slightly when the stepping stone moves downward, forming a driving force, thereby reducing the downward movement amplitude of the stepping stone assembly and improving safety. Two spaced stepping stone assemblies and a hinged rod are used to form a lever structure. With the spaced stepping stone assemblies as the fulcrums, the force on the pressing plate is located at the center of the pressing plate, reducing the probability of wear on the edge of the pressing plate and improving its service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0024] Embodiment 1

[0025] As Figures 1-4As shown in the figure, a stepping stone in water with an aeration and oxygenation structure includes a base pile 1, which is composed of two cylindrical bases arranged side by side. Two groups of pressurization components 2 and two groups of oxygen exposure components 3 are arranged inside the base pile 1. The pressurization component 2 includes a hydraulic cavity 21 arranged inside the base pile 1, a pressure plate 22 adapted to the hydraulic cavity 21, and a transmission channel 25 communicated with the bottom of the hydraulic cavity 21. The pressurization component 2 is used to drive the oxygen exposure component 3 to aerate the water.

[0026] Four stepping stone components 4 are arranged at the upper end of the base pile 1. The stepping stone component 4 includes a sliding base 41 spanning above the base pile 1, a sliding block 42 slidably connected to the sliding base 41, a stepping stone main body 43 arranged above the sliding block 42, and a return spring 45 arranged below the sliding block 42 for pushing the sliding block 42 upward. The bottom ends of a pair of spaced sliding blocks 42 are jointly hinged with a hinge rod 27. A middle section of the hinge rod 27 is hinged with a connecting rod 28. The connecting rod 28 is located directly above the center of the pressure plate 22, and the connecting rod 28 is hinged with the top end of the pressure plate 22.

[0027] In this solution, a pressure plate 22 with a relatively large area is set as a pressurization component, so that the slight downward movement of the pressure plate 22 can cause the water in the hydraulic cavity 21 to flow, forming a driving force, thereby reducing the downward movement amplitude of the stepping stone component 4. Two spaced stepping stone components and a hinge rod are used to form a lever structure. When stepping on the stepping stone main body 43, with the spaced stepping stone components 4 as the fulcrum, the pressure plate 22 is pressed down. Even if the downward movement distance of the pressure plate 22 is very small, but its area is large, the water in the hydraulic cavity 21 enters the gas pressurization cavity 32 to push the piston 31 to move, pressurize the air for oxygen exposure. That is to say, this solution reduces the downward movement amplitude of the stepping stone by increasing the area of the pressure plate, making it improve the safety during stepping.

[0028] In order to reduce the problem of edge wear caused by the pressure plate 22 not being stressed at the center, the connection position between the pressure plate 22 and the connecting rod 28 is located at the center of the pressure plate 22. The downward pressures generated by the two stepping stone components 4 act downward through the same hinge rod 27, and this acting force acts on the center of the pressure plate 22 through the connecting rod 28, reducing the wear of the edge of the pressure plate 22 and extending the service life.

[0029] A limiting strip 23 is arranged at the upper edge of the pressure plate 22. A limiting convex strip 24 that slidably interacts with the limiting strip 23 is arranged on the inner wall of the base pile 1. A sealing ring is arranged on the circumferential surface of the pressure plate 22. Since the ratio of the major axis to the minor axis of the pressure plate 22 is very small, during the downward pressing process, the pressure plate 22 is prone to tilt after being stressed, causing wear of the side wall sealing ring structure. Therefore, the limiting strip 23 is arranged to limit the vertical downward sliding of the pressure plate 22.

[0030] The length and width of the sliding block 42 are smaller than those of the stepping stone main body 43. The return springs 45 are distributed at the four corners below the sliding block 42. The sliding block 42 is in the shape of a boss. A bottom groove 44 for the hinge rod 27 to extend downward is provided at the bottom end of the sliding base 41. To increase the aesthetics, the width of the sliding block 42 being smaller than that of the stepping stone main body 43 can make the appearance simple and easy to conceal. The shape of the sliding block 42 limits the sliding amplitude of the stepping stone main body 43 up and down.

[0031] The aeration component 3 includes a gas pressurization chamber 32 communicated with the transmission channel 25. A piston 31 is provided at one end of the gas pressurization chamber 32 close to the transmission channel 25, and a one-way air inlet 33 and a one-way aeration port 34 are provided at the other end. The one-way air inlet 33 is extended by a pipeline to communicate with the atmosphere and is provided with a one-way valve 35 for air intake. The one-way aeration port 34 is communicated to the aeration disc 36 and is provided with a one-way valve 35 for outward aeration. The aeration component 3 transmits power through the hydraulic chamber 21 with a larger area to the piston 31 with a larger length-diameter ratio. The piston 31 will not be inclined due to force and cause wear, and it is not easy to leak air at the edge. Moreover, the stroke amplitude of the pressing plate 22 is small, but when transmitted to the piston 31, the piston 31 has a larger movement amplitude for air intake and aeration. For the return movement of the piston 31, the return spring 45 drives the sliding block 42 to return, and then drives the pressing plate 22 to return. The negative pressure in the hydraulic chamber 21 sucks the piston 31 back to its original position.

[0032] Both ends of the hinge rod 27 are bent upward for hinging with the sliding block 42. The upper parts of the two cylindrical bases communicate with each other for the hinge rod 27 to pass through, which is a structural optimization to eliminate structural interference.

[0033] Embodiment 2

[0034] In Embodiment 1, due to the large area and small thickness of the pressing plate 22, after being worn after multiple uses, a small amount of water leakage may occur at the edge of the pressing plate 22. Although the small amount of water leakage has little influence on the downward pressure of the pressing plate 22, when the pressing plate 22 moves downward to increase pressure, the water moves upward through the edge of the pressing plate 22, resulting in a gradual decrease in the water volume in the hydraulic chamber 21, and further reducing the pushing effect on the piston 31. Therefore, on the basis of Embodiment 1, this embodiment optimizes the return process of the pressing plate 22 and the piston 31 to reduce the influence caused by water leakage at the edge of the pressing plate 22.

[0035] As Figures 5-6As shown in the figure, based on Embodiment 1, a first spring 37 for pushing the piston 31 to move towards one end of the transmission channel 25 is provided inside the gas pressurization chamber 32. A one-way water inlet valve 26 for allowing water to enter below the pressing plate 22 is provided on the surface of the pressing plate 22. The one-way water inlet valve 26 replenishes water below the pressing plate 22 when the pressing plate 22 moves upward. After the one-way water inlet valve 26 is provided, the hydraulic chamber 21 loses its adsorption force when the pressing plate 22 moves upward, and the piston 31 cannot reset. Therefore, the reset of the piston 31 is achieved by the first spring 37. In this solution, by optimizing the reset process of the piston 31 and the pressing plate 22, even if there is a small amount of water leakage at the edge of the pressing plate 22, the impact on the pressure increase in the hydraulic chamber 21 can be ignored. The stepping on the stepping stone body 43 occurs instantaneously, and the downward movement of the pressing plate 22 also occurs instantaneously. Therefore, a small amount of water leakage does not affect the pressing plate 22 from quickly pressing the water in the hydraulic chamber 21 into the gas pressurization chamber 32. Even if the problem of poor sealing due to the increased area of the pressing plate 22 can be ignored in this embodiment.

[0036] Specific implementation method: When a pedestrian steps on the stepping stone body 43, the stepping stone body 43 moves downward slightly. Taking the spaced stepping component 4 as a fulcrum, a downward pressure is generated at the connecting rod 28. This pressure acts on the center of the pressing plate 22, causing the pressing plate 22 to move downward, pressing the water in the hydraulic chamber 21 into the gas pressurization chamber 32, and pushing the piston 31 to move. The piston 31 pushes the gas out and enters the water through the aeration disc 36. When the pedestrian leaves the stepping stone body 43, the return spring 45 causes the sliding block 42 to move upward, the pressing plate 22 moves upward correspondingly, the piston 31 resets, and air is sucked into the gas pressurization chamber 32 from the atmosphere through the one-way air inlet 33.

[0037] If two stepping components 4 on the same hinge rod 27 are stepped on simultaneously, the pressing plate 22 will also move downward without being affected.

[0038] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
