Description

Technical Field

[0001] This invention relates to the field of rainwater drainage, and more specifically to a floating overflow outlet. Background Technology

[0002] Rainwater can be absorbed, stored, and utilized naturally. However, effectively controlling the water level in sunken green spaces to prevent overflow and disruption of surrounding roads remains a pressing issue. While existing overflow designs can partially address this problem, most rely on fixed structures and cannot dynamically adjust to changes in rainfall volume. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a floating overflow port.

[0004] According to the technical solution provided in the embodiments of this application, a floating overflow port includes a first floating grate and a second floating grate. The first floating grate is arranged in a horizontal direction, and the second floating grate is fixedly arranged at the four edges below it. The first floating grate is fixedly connected to a floating plate by a support rod.

[0005] The second floating grate has four sections, which are fixedly connected to each other and form a rectangle. The second floating grate is movably connected to the inner wall of the well chamber via a slide rail. The well chamber is also equipped with a drain pipe on its side. When rainwater enters the well chamber, the float plate causes the first floating grate and the second floating grate to float upwards, increasing the amount of rainwater entering.

[0006] Furthermore, in this invention, both the first floating grate and the second floating grate are provided with a plurality of equally spaced drain outlets.

[0007] In this invention, the upper end of the support rod is fixedly connected to the middle of the first floating grate, and the lower end is fixedly connected to a float plate.

[0008] In this invention, the well chamber is a downwardly extending cuboid with a bottom plate at the lower end, and the upper end of the well chamber is an open end with a downwardly extending sinking groove so that the first floating grate can be placed in the sinking groove.

[0009] In this invention, the cuboid well chamber has a cavity in the middle for rainwater to enter, and is connected to the drainage pipe.

[0010] In this invention, the well chamber is further made of C20 fine stone concrete, and the top surface of the well chamber (5) is kept at the same horizontal line as the ground.

[0011] In this invention, the upper end of the well chamber is provided with a slide rail groove, and the slide rail is set in the slide rail groove. The four right angles formed by the second floating grate are provided with sliders and are movably connected to the slide rail.

[0012] Furthermore, in this invention, the drain pipe is spaced apart from the upper and lower ends of the well chamber.

[0013] In summary, the beneficial effects of this application are as follows: In use, the first floating grate is horizontally positioned, while the second floating grate is vertically positioned. The second floating grate has four sections that can form a rectangle, and it is fixedly connected to the lower edge of the first floating grate. The first and second floating grates are movably connected to the inner wall of the upper end of the manhole via slide rails, which also prevent them from dislodging. The first floating grate is fixedly connected to a float plate via a support rod. When rainwater enters the manhole, the float plate causes the first and second floating grates to rise, accelerating the entry of rainwater. Excess rainwater can flow out through the drain pipe. This device improves drainage capacity, prevents overflow pollution, enhances visual appeal, and simplifies maintenance. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, a floating overflow outlet of this application is composed of a first floating grate 1, a second floating grate 2, a support rod 3, a float plate 4, a well chamber 5, a bottom plate 6, a slide rail 7, a drain pipe 8, etc.

[0023] like Figure 1 - Figure 3 As shown, the floating overflow outlet is suitable for placement in a low-lying location. When the water level in the well chamber is low, the first floating grate 1 and the second floating grate 2 are positioned low via the float plate 4. When the water level is high, the float plate 4 pushes the first floating grate 1 and the second floating grate 2 upwards to float completely, and they are movably connected to the well chamber 5 via the slide rail 7 to prevent them from falling off. Both the first floating grate 1 and the second floating grate 2 are rectangular and have several equally spaced drainage outlets. When rainwater enters the well chamber through the first floating grate 1, the water level in the well chamber rises. As the rainwater rises, the first floating grate 1 and the second floating grate 2 rise with it, and rainwater begins to enter through the second floating grate 2, accelerating the inflow of rainwater. Excess rainwater is discharged through the drain pipe 8. The drain pipe 8 is positioned 300mm from the bottom of the well chamber 5, allowing the float plate 4 to have sufficient vertical movement.

[0024] like Figure 1 - Figure 3 As shown, the first floating grate 1 is horizontally positioned, and the second floating grate 2 is vertically positioned. There are four second floating grates 2, which can form a rectangle and are fixedly connected to the lower edge of the first floating grate 1. The first floating grate 1 is 750mm long and 450mm wide. The height of the rectangle formed by the second floating grates 2 is 300mm, which is the same height to which the float 4 can float within the well chamber 5. When the second floating grate 2 is not floating, the distance between its bottom surface and the drain pipe 8 is 200mm. The diameter of the drain pipe 8 is 300mm. The interior width of the well chamber 5 is 360mm, the width of the bottom plate 6 is 1260mm, and the height of both is 100mm.

[0025] like Figure 1 - Figure 3 As shown, the upper end of the support rod 3 is fixedly connected to the middle of the first floating grate 1, and the lower end is fixedly connected to the float plate 4. The first floating grate 1, the second floating grate 2, and the float plate 4 are all made of composite resin, which makes them easy to float. The support rod 3 is also made of composite resin. A slide rail 7 is provided at the upper end of the inner wall of the well chamber 5, which is movably connected to the slider on the second floating grate 2. The purpose of the slide rail 7 is to prevent the first floating grate 1 and the second floating grate 2 from falling out of their original positions when they move upwards, and also to prevent the float plate 4 from tilting when it floats. The drain outlets that are equally spaced on the first floating grate 1 and the second floating grate 2 can prevent dead branches, leaves, etc. from entering the well chamber 5 and causing blockage of the well chamber 5 and the drain pipe 8.

[0026] like Figure 1 - Figure 3 As shown, the well chamber 5 is a downward-extending cuboid with a rainwater inlet chamber in the middle. The upper end of the well chamber 5 has an outward-extending slide rail groove for fixing the slide rail 7 within it. The upper end of the well chamber 5 has an open end with a downward-extending sinking groove. After all the rainwater in the well chamber 5 has been drained, the second floating grate 2, in conjunction with the first floating grate 1, sinks into the sinking groove, and the first floating grate eventually reaches the same height as the ground. A 300mm diameter drain pipe 8 is installed on one side inside the well chamber 5.

[0027] In summary, this structure effectively handles large amounts of rainwater, especially during extreme weather, reducing the risk of urban flooding. The floating overflow wells prevent excessive rainwater from overflowing again, thus preventing environmental pollution or entry into the building. The floating overflow design relies solely on buoyancy, resulting in a simple structure and easy, convenient maintenance.

[0028] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
