TECHNICAL FIELD
[0001] The utility model relates to the field of water supply and drainage, especially to rainwater inlet deodorization box. BACKGROUND
[0002] When the accumulated water on the road surface enters the sewer, sundries will enter the sewer, and the sundries will produce odor after fermentation, which will be diffused to the ground through the rainwater well cover, resulting in the odor of the ground environment. The existing method is to set a one-way valve in the rainwater well cover, which only allows rainwater to enter the sewer and does not allow fluid in the sewer to flow back to the ground. The existing one-way valve in the rainwater well cover has poor reliability and is easily stuck and cannot be opened, resulting in accumulated water on the road. Or no matter the water volume, it remains open, resulting in continuous diffusion of odor when the water volume is small. SUMMARY
[0003] The utility model aims at overcoming the above-mentioned defects and providing a rainwater inlet deodorization box with high reliability.
[0004] The rainwater inlet deodorization box comprises a box body and two door plates. The box body comprises a bucket body and a retaining rim. The bucket body is conical with a wide upper end and a narrow lower end. The retaining rim is provided at the upper end of the bucket body and extends outward horizontally. The bottom of the bucket body is provided with a drain port. The middle part of the drain port is provided with a stop block. The two ends of the drain port are respectively provided with a first hinge point and a second hinge point. The middle parts of the two door plates are respectively hinged to the first hinge point and the second hinge point. One end of the door plate is located below the drain port to form a closed end. The other end of the door plate extends outward to form an extended end. The door plate can be rotated to abut against the stop block at the closed end or abut against the outer wall of the bucket body at the extended end. When the closed ends of the two door plates abut against the stop block, the drain port is closed by the two door plates. The extended end of the door plate is provided with a counterweight.
[0005] The two door plates are not easily stuck at the same time, and have high reliability. The bucket body is in the shape of a quadrangular pyramid. The inner side slope of the bucket body helps to guide water into the drain port. The outer side slope of the bucket body allows the door plate to be opened to the limit position where the extended end of the door plate abuts against the outer side slope of the bucket body. This avoids the door plate being opened too large to be closed. Moreover, the outer side of the bucket body can provide large-area support for the extended end of the door plate, reducing the deformation of the door plate.
[0006] Preferably, the two door plates are a first door plate and a second door plate. The first door plate is hinged to the first hinge point, and the second door plate is hinged to the second hinge point. The weight of the counterweight of the first door plate is greater than that of the second door plate. When the amount of accumulated water is small, the second door plate is first opened to discharge the accumulated water. When the amount of accumulated water is large, the first door plate is also opened, improving the flow of the drain port.
[0007] Preferably, the two door plates are a first door plate and a second door plate, the first door plate is hinged to the first hinge point, the length of the closed end of the first door plate is greater than the length of the closed end of the second door plate, the moment difference of the outer end and the closed end of the first door plate to the first hinge point is a first moment difference, the moment difference of the outer end and the closed end of the second door plate to the second hinge point is a second moment difference, and the first moment difference is greater than the second moment difference. When the amount of accumulated water is small, the second door plate is first pushed open to drain the accumulated water, and when the amount of accumulated water is large, the first door plate is also pushed open to increase the flow rate of the drain.
[0008] Preferably, the stop block comprises a first stop block and a second stop block, the first stop block is used for stopping the first door plate, and the second stop block is used for stopping the second door plate. The height of the bottom surface of the first stop block is greater than the height of the bottom surface of the second stop block. The position of the first door plate when closed is higher than the position of the second door plate when closed. The accumulated water entering above the first door plate is guided to the second door plate. When the amount of accumulated water reaches a certain amount, the second door plate is first pushed open to drain the accumulated water.
[0009] Preferably, the bottom surface of the outer end of the door plate is provided with a protruding strip protruding downward, the protruding strip is provided with a channel extending in the front-rear direction, and the counterweight block is arranged in the channel. The counterweight block is directly put into or taken out from the channel. By replacing the counterweight blocks on the first door plate and the second door plate, the opening order and the opening condition of the first door plate and the second door plate can be adjusted.
[0010] By adopting the technical scheme, the utility model has the advantages that two door plates are arranged, the two door plates are not easy to be stuck simultaneously, and the reliability is high. The bucket body is in the shape of a quadrangular pyramid. The outer side surface of the bucket body can give large-area support to the outer end of the door plate, and the deformation of the door plate is reduced. The first door plate and the second door plate are sequentially opened according to different amounts of accumulated water, and the diffusion of odor when a small amount of accumulated water is drained is reduced.
