Description

Technical Field

[0001] This utility model belongs to the field of rainwater well cover technology, and relates to a rainwater well cover with a reinforced structure. Background Technology

[0002] Stormwater manhole covers are typically installed on roads and streets to drain accumulated water into sewers, and are widely used in urban construction and public works projects. By using stormwater manhole covers, wastewater and rainwater can be smoothly discharged into the sewers, ensuring the cleanliness and aesthetics of the urban environment while preventing rainwater from accumulating on city streets.

[0003] However, existing storm drain covers still have some shortcomings. As fallen leaves, garbage and other debris often accumulate on the road, if these debris are not cleaned up in time during rainy days, the inlets on the manhole covers can easily become blocked, preventing rainwater from draining properly. To improve the drainage efficiency of storm drain covers, multiple drainage outlets can be set on the manhole covers. However, setting too many drainage outlets can easily affect the structural strength of the manhole covers and cause safety hazards. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing a rainwater well cover with a reinforced structure. The technical problem to be solved by this utility model is: how to improve the structural strength of the rainwater well cover.

[0005] The objective of this utility model can be achieved through the following technical solution: A rainwater well cover with a reinforced structure includes a cover body, the top of the cover body is provided with several water inlets, a baffle for sealing is provided above the water inlets, the bottom of the baffle is integrally connected to the cover body, the side wall of the baffle is provided with several filter holes, the filter holes are connected to the water inlets, the bottom of the cover body is provided with several ribs, the ribs are provided on the bottom periphery of the water inlets, the several ribs are connected to each other, the bottom of the cover body is provided with a sleeve, the bottom edge of the cover body is provided with a downwardly extending annular connecting part, the connecting part is inserted into the sleeve and fixedly connected.

[0006] In this design, the top of the cover has multiple large water inlets, and baffles are installed on top of the inlets to prevent debris from directly entering the sewer and causing blockages. Rainwater from the road surface can flow into the inlets through filter holes on the side wall and then into the sewer. The multiple filter holes not only prevent blockages but also increase the speed at which rainwater flows into the manhole cover, achieving efficient drainage. Through the above method, ribs are set at the bottom of the cover. The interconnected ribs increase the thickness of the cover, reducing its weight while improving its structural strength. The sleeve connected to the bottom of the cover prevents the cover from being washed away by rainwater and also disperses the impact force on the cover.

[0007] In the aforementioned reinforced rainwater well cover, the inlet and baffle are curved strips, with one end of the inlet located near the center of the cover. The inlet radiates outward from the center of the cover, facilitating rainwater flow into it.

[0008] In the aforementioned reinforced storm drain cover, the ribs correspond to the inlet, and the ribs are spiral-shaped, radiating outwards from the center. Adjacent ribs are connected by crossbars, which together form a ring. Using crossbars to connect the ribs allows the stress on the ribs to be distributed, improving the structural strength of the cover.

[0009] In the aforementioned reinforced storm drain cover, the end of the inlet near the center is narrower than the end near the edge. Increasing the width of the outer end of the inlet improves the drainage speed.

[0010] In the aforementioned reinforced rainwater well cover, the connecting part is provided with several mounting posts, each with a threaded hole inside. The cover body and the sleeve are fixed together by bolts. The bolts are drilled into the threaded holes from the top of the cover body to facilitate the connection between the cover body and the sleeve.

[0011] In the aforementioned reinforced rainwater well cover, a support portion is provided on the inner wall of the sleeve, and the bottom of the connecting portion and the mounting post abuts against the support portion. The bottom of the bolt is drilled into the support portion to fix the sleeve to the cover body.

[0012] In the aforementioned reinforced rainwater well cover, a plurality of water inlet holes are provided on the surface of the cover body, and the water inlet holes are distributed around the water inlet. The small water inlet holes on the cover body allow rainwater to enter directly through them, and these holes assist in drainage, improving drainage efficiency.

[0013] In the aforementioned reinforced storm drain cover, the top of the baffle is provided with an upwardly protruding anti-slip block. The anti-slip block serves to prevent slippage and improve the safety of the cover.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. In this design, ribs are provided at the bottom of the cover. The interconnected ribs can share the impact force on the top of the cover and improve the structural strength of the cover. The sleeve structure connected to the bottom of the cover can prevent the cover from being washed away by rainwater and can also disperse the impact force on the cover. Attached Figure Description
