Description

Technical Field

[0001] The utility model relates to the field of municipal drainage facilities, in particular to a non-powered anti-odor rainwater outlet structure. Background Art

[0002] Most of the stormwater inlets are facing serious blockage problems, and fallen leaves and mud are one of the main reasons for the blockage of stormwater inlets. The blocked stormwater inlets seriously affect the drainage capacity of the city. During the rainy season, it is easy to cause urban waterlogging, seriously affecting the normal order of the city. The fallen leaves and garbage that fall into the stormwater wells are not only difficult to clean up, but also seriously block the urban drainage system. Long-term blockage will also emit odors, which has a great impact on the lives, travel and normal operation of the city of residents.

[0003] Traditional automatic closing rainwater outlet sewage interception devices mostly use spring rebound, which has the problems of short device life, complex structure and easy damage, and low rebound efficiency. A Chinese patent (CN110593383A) discloses an integrated lever-type automatic opening and closing rainwater outlet sewage interception device, which uses the interaction between the gravity plate and the water collection plate to achieve automatic opening and closing under the action of water pressure and gravity, can effectively block solid waste, and can be blocked in the non-water collection state to reduce odor overflow; but the guide plate it uses blocks part of the water inlet channel of the rainwater outlet, which affects the water inlet efficiency of the rainwater outlet when the water inlet is large, and it is easy to form a deep water accumulation area at the rainwater outlet. Utility Model Content

[0004] The purpose of the utility model is to provide a non-powered anti-odor rainwater outlet structure in response to the defects of the prior art. When there is no need for water collection and drainage, the flap maintains horizontal balance under the action of its own gravity, thereby blocking a partial cross-section of the drainage channel and reducing the overflow of odor from the pipe under the drainage outlet. When water is taken in through the eccentrically distributed water inlet, the flap can be opened due to unbalanced force and rotated under the action of the water flow, thereby reducing the impact on the water inlet and drainage of the rainwater outlet when the water inlet is large.

[0005] In order to achieve the above purpose, the following technical solutions are adopted:

[0006] A non-powered anti-odor rainwater outlet structure comprises a rainwater outlet and a flap, wherein a drainage channel is formed in the rainwater outlet, and the flap is rotatably installed in the drainage channel, and the rotation axis of the flap coincides with the center line of the flap, so that when the flap is in balance, the plane where the flap is located is horizontally distributed and blocks the drainage channel; the flap can rotate around the rotation axis; the top of the drainage channel is a water inlet, and the water inlet is eccentrically arranged relative to the drainage channel where the flap is located.

[0007] Furthermore, in the direction of the rotation axis of the flap, both ends of the flap are rotatably connected to the inner wall of the drainage channel through a rotating shaft.

[0008] Furthermore, a bearing is installed on the inner wall of the drainage channel through a shaft seat, and the bearing and the rotating shaft are matched one by one.

[0009] Furthermore, a gap is left between the outer periphery of the flap and the inner periphery of the drainage channel.

[0010] Furthermore, the rotation axis of the flap passes through the center of gravity of the flap, and the flap is symmetrically distributed relative to the rotation axis.

[0011] Furthermore, the horizontal cross-section of the drainage channel is rectangular, and the flap is a rectangular plate.

[0012] Furthermore, the water inlet is surrounded by an annular gasket, and a grate for shielding the water inlet is carried on the annular gasket.

[0013] Furthermore, the horizontal cross-section of the water inlet is rectangular, the three circumferential side walls of the water inlet are coplanar with the corresponding three side walls of the drainage channel, and the remaining axial side wall of the water inlet is spaced apart from the remaining side wall of the drainage channel.

[0014] Furthermore, a side wall on one side of the drainage channel extends toward the inside of the drainage channel to form a supporting portion for the annular gasket.

[0015] Furthermore, the vertical axes of the water inlet are spaced apart from each other, and the vertical plane where the rotation axis of the flap is located is spaced apart from the vertical axis of the water inlet.

[0016] Compared with the prior art, the utility model has the following advantages and positive effects:

[0017] (1) In order to solve the problem that the current anti-odor rainwater inlet structure will affect the efficiency of water inlet and drainage, when there is no need for water collection and drainage, the flap maintains horizontal balance under the action of its own gravity, thereby blocking part of the cross-section of the drainage channel and reducing the overflow of odor from the pipe under the drainage outlet. When water enters the eccentrically distributed water inlet, the flap can be opened due to unbalanced force, and at the same time, it rotates under the action of water flow, thereby reducing the impact on the water inlet and drainage when the water inlet is large.

[0018] (2) The flap itself is a symmetrical structure that can maintain balance through gravity, and can flip and rotate when impacted by unbalanced water flow. It can also reduce the impact of high-speed rainwater on the pipe under the stormwater outlet and maintain the structural stability of the stormwater outlet.

[0019] (3) A gap is left between the flap and the drainage channel, which allows small impurities that cannot be filtered by some grates to pass through, reducing the sticking of the flap and improving the smoothness of the flap's operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In a typical implementation of the present invention, Figure 1-Figure 3 As shown, a non-powered anti-odor rainwater outlet structure is proposed.

[0026] The rainwater inlet 1 that uses a rebound member to drive a plate to achieve blocking is easy to be damaged, and the traditional blocking plate that is opened by the impact of water flow will affect the water inlet efficiency and is difficult to meet the drainage work requirements when the water inlet is large. Based on this, this embodiment provides a non-powered anti-odor rainwater inlet structure, which uses a flap 6 that is self-balanced under gravity as a blocking structure to shield and protect the drainage channel 2 in the rainwater inlet 1, thereby reducing the leakage and overflow of odor in the pipe 3 under the rainwater inlet 1. At the same time, the flap 6 can be rotated. When collecting water, the water flow impacts the flap 6 to rotate the flap 6 to promote the downward discharge of water. Compared with the guide plate structure, it can reduce the blocking effect on water collection and drainage, and ensure the water inlet and drainage efficiency.

[0027] See also Figure 1 The non-powered anti-odor rainwater inlet structure is mainly composed of a rainwater inlet 1 and a flap 6, and the installation method of the flap 6 and the arrangement method of the water inlet 8 are described in detail.

[0028] A drainage channel 2 is formed in the rainwater inlet 1, and a flap 6 is rotatably installed in the drainage channel 2. The flap 6 can rotate around its rotation axis in the drainage channel 2, and the rotation axis coincides with the center line of the flap 6, ensuring that the flap 6 is horizontally distributed when balanced. The top of the drainage channel 2 is a water inlet 8, which is eccentrically arranged relative to the drainage channel 2 where the flap 6 is located; the eccentric arrangement of the water inlet 8 relative to the drainage channel 2 where the flap 6 is located allows the flap 6 to be opened by the unbalanced force of the water falling from the water inlet 8 when water enters.

[0029] By shielding part of the cross section of the drainage channel 2 in a balanced state, the overflow of odor from the pipe 3 under the drainage outlet is effectively reduced when there is no need for water collection and drainage, thereby improving the environmental quality and meeting environmental protection requirements. The eccentrically arranged water inlet 8 enables the flap 6 to open automatically when water enters and rotate under the action of water flow, reducing the impact on the water inlet and drainage of the rainwater outlet 1 when the water inlet is large; avoiding the situation where the water flow is blocked, and enhancing the practicality of the rainwater outlet 1.

[0030] The unpowered anti-odor rainwater outlet structure is unpowered as a whole, without elastic parts, and does not require external energy to drive the flap 6 to open and close, which not only reduces the operating cost but also meets the energy-saving requirements.

[0031] like Figure 2 and Figure 3 As shown, in the direction of the rotation axis of the flap 6, the two ends of the flap 6 are rotatably connected to the inner wall of the drainage channel 2 through the rotating shaft 5, ensuring that the flap 6 can flexibly rotate around its rotation axis. A bearing 4 is installed on the inner wall of the drainage channel 2 through an axle seat, and the bearing 4 and the rotating shaft 5 are matched one by one; the axle seat is fixed on the inner wall of the drainage channel 2, and the bearing 4 is installed through the axle seat, the outer ring of the bearing 4 is fixed to the axle seat, and the inner ring of the bearing 4 is sleeved outside the rotating shaft 5 to form a rotating connection, reduce the friction when the flap 6 rotates, and make the flap 6 rotate more smoothly.

[0032] In this embodiment, the rotating shaft 5 can be made of metal materials such as cast iron, the bearing 4 can be made of a ceramic bearing 4, and the flap 6 can be made of a PVC plastic plate.

[0033] A gap is left between the outer periphery of the flap 6 and the inner periphery of the drainage channel 2, which ensures that the flap 6 will not rub or get stuck with the inner wall of the drainage channel 2 when rotating, and allows a small amount of small-volume impurities to pass through the gap, reducing the problem of impurities accumulating on the surface of the flap 6.

[0034] The rotation axis of the flap 6 passes through the center of gravity of the flap 6, and the flap 6 is symmetrically distributed relative to its rotation axis, which ensures that the flap 6 can remain horizontal in a balanced state, and the gravity is evenly distributed, thereby enhancing stability.

[0035] The horizontal cross section of the drainage channel 2 is rectangular, and the flap 6 is a rectangular plate. The flap 6 matches the shape of the drainage channel 2, increasing the horizontal cross section of the drainage channel 2 covered by the flap 6 to achieve a good shielding effect.

[0036] The water inlet 8 is surrounded by an annular gasket 7, on which a grate 9 is carried to block the water inlet 8. It is understandable that a groove for accommodating the grate 9 can also be provided on the annular gasket 7 to constrain the horizontal position of the grate 9. The grate 9 can prevent large debris from entering the drainage channel 2, and can allow water to enter through the gaps in the grate 9.

[0037] The horizontal cross-section of the water inlet 8 is rectangular, and the three circumferential side walls of the water inlet 8 are coplanar with the corresponding three side walls of the drainage channel 2, and the remaining axial side wall of the water inlet 8 is spaced apart from the remaining side wall of the drainage channel 2; the vertical axis of the water inlet 8 is spaced apart from the vertical axis of the water inlet 8, and the vertical plane where the rotation axis of the flap 6 is located is spaced apart from the vertical axis of the water inlet 8, forming an eccentric distribution state, and the side wall on one side of the drainage channel 2 extends toward the inside of the drainage channel 2 to form a support portion 10 for the annular gasket 7, thereby ensuring the structural strength of the water inlet 8, so that the flap 6 can be smoothly opened under the unbalanced impact force of the water flowing into the eccentric water inlet 8, thereby ensuring the drainage effect.

[0038] In practical applications, the non-powered anti-odor rainwater inlet structure can be widely used in drainage systems of urban roads, squares, parks and other places. Since it adopts a non-powered design and does not require external energy drive, the installation and maintenance costs are low and it is suitable for large-scale deployment.

[0039] In addition, the anti-odor function of the non-powered anti-odor rainwater outlet structure can effectively improve the environmental quality of public places and improve people's quality of life. In the rainy season or heavy rain, its good drainage performance can ensure the efficient operation of the drainage system and prevent the occurrence of water accumulation.

[0040] The grate 9 is stably supported by the annular spacer 7, has a long service life and stable performance, can adapt to various severe climate and environmental conditions, and has broad prospects and potential in practical applications.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
