Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure construction, in particular to an anti-blocking drainage device with a closed structure. Background Art
[0002] With the development of the national construction industry, in order to improve construction efficiency and reduce costs, current construction generally uses steel structures in construction. However, some components have relatively closed structures inside, and water is not easy to evaporate after entering, which will cause water accumulation in the closed structure and corrode the paint inside the component. Therefore, during construction, drainage holes are usually dug at the bottom of the component to drain the accumulated water, keep the inside of the component dry, and extend the service life of the component.
[0003] At present, the main defects of conventional drain outlets are: if the size of the drain outlet is set slightly smaller, it is easy to be blocked by leaves, sand and the like mixed in the accumulated water; if the size of the drain outlet is set slightly larger, it may affect the structural strength and aesthetics of the component. Therefore, it is necessary to provide a closed structure anti-blocking drainage device that can solve the problem of easy blockage of the component drain outlet in the prior art. Summary of the invention
[0004] The utility model aims to provide a closed structure anti-clogging drainage device, which can solve the problem that the drainage outlet of the component is easily blocked in the prior art.
[0005] The utility model is achieved in this way:
[0006] A closed structure anti-clogging drainage device comprises a bottom plate, a limiting ring and a floating ball; a drainage port is formed on the bottom plate, the bottom plate is mounted on the inner wall of a component, and the drainage port is aligned with the drainage hole on the component; the limiting ring is an inverted U-shaped structure, a plurality of limiting rings are cross-arranged on the bottom plate and located in the component, a containing cavity connected to the inside of the component is formed between the plurality of limiting rings and the bottom plate, a floating ball can be floatably arranged in the containing cavity, and the bottom of the floating ball can fall onto the bottom plate and temporarily block the drainage port.
[0007] An extension portion is provided at the bottom of the drain port, and the extension portion penetrates the drain hole and extends to the bottom of the component.
[0008] The plurality of limiting rings are provided with additional limiting rings, and the additional limiting rings horizontally surround the outer sides of the middle parts of the plurality of limiting rings.
[0009] The plurality of limiting rings, the additional limiting ring and the bottom plate are welded into an integrated structure.
[0010] The drain outlet is a spherical structure that is wide at the top and narrow at the bottom, and the spherical structure matches the outer wall of the float so that the lower part of the float can be embedded in the spherical structure. The bottom opening diameter and the extension diameter of the spherical structure are consistent with the aperture of the drain hole.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The utility model is provided with a bottom plate, a limit ring and a float, so that the float can float up and down in the accommodating cavity formed by the bottom plate and the limit ring. When the float floats up under the action of accumulated water, the gap formed between the float and the drain outlet can meet the drainage demand of the accumulated water inside the component, and can block the leaves, sand and other debris mixed in the accumulated water through the bottom plate, the limit ring and the float as well as the smaller gap, effectively avoiding the blockage of the drain outlet while ensuring the drainage effect, so that the drain outlet can be designed to be smaller, avoiding the paint shedding and rust caused by long-term immersion in water inside the component, and improving the structural strength and aesthetics of the component.
[0013] 2. The utility model is provided with a limit ring and an additional limit ring. The two limit rings and the additional limit ring in the middle can limit the horizontal floating of the float from the front, back, left and right directions, thereby ensuring the temporary blocking effect of the float on the drain outlet and the floating drainage effect; at the same time, the gap between the limit ring and the additional limit ring is small, which is conducive to blocking water debris such as leaves and sand particles, further ensuring the drainage effect while effectively avoiding the drain outlet from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a cross-sectional view of the utility model's closed structure anti-clogging drainage device.
[0015] In the figure, 1 is a bottom plate, 101 is a drain outlet, 102 is an extension portion, 2 is a limiting ring, 3 is a floating ball, 4 is a component, 401 is a drain hole, and 5 is an additional limiting ring. DETAILED DESCRIPTION
[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Please see attached Figure 1 A closed structure anti-clogging drainage device includes a bottom plate 1, a limiting ring 2 and a floating ball 3; a drainage port 101 is formed on the bottom plate 1, the bottom plate 1 is installed on the inner wall of a component 4, and the drainage port 101 is aligned with a drainage hole 401 on the component 4; the limiting ring 2 is an inverted U-shaped structure, a plurality of limiting rings 2 are cross-arranged on the bottom plate 1 and located in the component 4, a containing cavity connected to the inside of the component 4 is formed between the plurality of limiting rings 2 and the bottom plate 1, the floating ball 3 can be floated in the containing cavity, and the bottom of the floating ball 3 can fall onto the bottom plate 1 and temporarily block the drainage port 101.
[0018] Preferably, the height of the limit ring 2 can be determined according to the diameter of the float 3 and the internal height of the component 4. The limit ring 2 is used to limit the floating height of the float 3 and the horizontal floating of the float 3, so that the float 3 is confined in the accommodating cavity and floats up and down with the water level.
[0019] When water accumulates in the component 4 and the float 3 floats up, the bottom of the float 3 escapes from the drain port 101, and a gap is formed between the float 3 and the drain port 101 to allow the water inside the component 4 to be discharged. However, debris such as leaves and sand mixed in the accumulated water can be blocked by the limit ring 2 and the float 3 and will not enter the accommodating cavity and block the drain port 101 and the drain hole 401, so that the aperture of the drain hole 401 can be designed to be smaller without affecting the drainage effect. After the water level drops, the float 3 falls onto the bottom plate 1 and temporarily blocks the drain port 101.
[0020] There are preferably at least two limiting rings 2 to ensure that the float 3 can be confined in the accommodating cavity. When the volume of the debris is small, the number of limiting rings 2 can be increased according to the actual blocking requirements. In actual construction, the thickness of the bottom plate 1 should be as small as possible to ensure that the accumulated water in the component 4 can be drained. In order to clearly show the structure of the bottom plate 1, the following Figure 1 The thickness of the bottom plate 1 in the figure has been thickened.
[0021] An extension portion 102 is disposed at the bottom of the drain port 101 . The extension portion 102 passes through the drain hole 401 and extends to the bottom of the component 4 .
[0022] The length of the extension portion 102 is determined according to the wall thickness of the component 4 to ensure that the accumulated water in the component 4 can be discharged from the component 4 .
[0023] The plurality of limiting rings 2 are provided with additional limiting rings 5 , which horizontally surround the outer middle parts of the plurality of limiting rings 2 .
[0024] The additional limiting ring 5 can reduce the gap between adjacent limiting rings 2, thereby improving the blocking effect on debris such as leaves and sand particles, without affecting the drainage effect.
[0025] The plurality of limiting rings 2, the additional limiting ring 5 and the bottom plate 1 are welded into an integrated structure, which has high structural strength and long service life.
[0026] Preferably, the plurality of limiting rings 2, the additional limiting ring 5 and the bottom plate 1 can all be made of stainless steel, with an anti-corrosion coating applied on the surface, and have good durability.
[0027] The drain outlet 101 is a spherical structure that is wide at the top and narrow at the bottom, and the spherical structure matches the outer wall of the float 3 so that the lower part of the float 3 can be embedded in the spherical structure. The bottom opening diameter of the spherical structure and the diameter of the extension part 102 are consistent with the aperture of the drain hole 401.
[0028] When the floating ball 3 falls, it can be embedded in the spherical structure, reducing the influence of external water vapor on the internal paint layer and other structures of the component 4, which is beneficial to increasing the service life of the component 4.
[0029] Please see attached Figure 1, the installation and use method of the utility model is:
[0030] A thin steel plate is used as the bottom plate 1, and a drain port 101 is provided on the bottom plate 1, and the bottom opening of the drain port has the same aperture as the drain hole 401. The extension portion 102 can be a round steel pipe, and the outer diameter of the extension portion 102 is consistent with the aperture of the drain hole, and the length of the extension portion 102 is greater than the wall thickness of the component 4. The extension portion 102 is welded at the bottom opening of the drain port 101.
[0031] The limiting ring 2 and the additional limiting ring 5 can be made of round steel pipes. The height of the limiting ring 2 is slightly larger than the diameter of the floating ball 3. Two limiting rings 2 can be used, which are arranged at 90 degrees in a cross manner, and can limit the horizontal movement of the floating ball 3 in the front, rear, left and right directions of the floating ball 3. The additional limiting ring 5 is arranged around the middle of the two limiting rings 2 to further limit the horizontal movement of the floating ball 3.
[0032] The float 3 can be a wooden or plastic hollow sphere, which is light in weight and can float under the action of water accumulated in the component 4.
[0033] The bottom plate 1 is welded to the inner wall of the component 4 so that the extension 102 passes through the drainage hole 401. When water accumulates inside the component 4, the float 3 can float up under the action of buoyancy to expose the drainage port 101, and the accumulated water in the component 4 can be discharged from the component 4 through the drainage port 101 and the extension 102.
[0034] The floating height of the float 3 is limited under the limit of the top of the limit ring 2, and the gap between the float 3 and the drain 101 is small, which can allow water to pass through to meet the purpose of drainage, but leaves, sand and other debris mixed in the water cannot pass through, thereby avoiding clogging of the drain 101. Since the interior of the component 4 is a relatively closed structure, the amount of accumulated water is small, and a small gap can meet the requirements of the drainage flow rate. The floating height of the float 3 in the limit ring 2 can be set according to the water accumulation of the component 4.
[0035] Furthermore, the two limit rings 2, the additional limit ring 5 and the float 3 can all form a barrier to debris such as leaves. At the same time, the bottom plate 1 forms a small step on the inner wall of the component 4, which can to a certain extent block the particles flowing with the water from approaching the drain outlet 101, further ensuring smooth drainage of the drain outlet 101.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
