Technical Field
[0001] The utility model relates to a drainage device, in particular to a drainage trough. Background Art
[0002] In the prior art, rainwater is usually collected in a reservoir. There are generally two ways for rainwater to enter the reservoir. One is through natural infiltration, which collects clean rainwater but has low efficiency. The other is through a gutter, which has high efficiency but poor cleanliness of collected rainwater and is prone to clogging. Existing gutter usually has sieve holes at the bottom, which can retain some debris at the bottom of the gutter when it is working. However, it is troublesome to clean these debris and it is not easy to clean them out from the gutter. At the same time, mud and sand can easily pass through the sieve holes into the pipe and accumulate in the pipe, which can easily cause the pipe to be blocked. Utility Model Content

DETAILED DESCRIPTION
[0017] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0018] The utility model provides a drainage trough, such as Figure 1-Figure 3As shown, the drainage trough is used for collecting rainwater in a water storage tank, and specifically comprises an outer shell 1 and an inner sleeve 2. A first filter plate 11 is hinged on the outer shell 1, and the first filter plate 11 can rotate around the hinged portion so that the first filter plate 11 can be in a closed state and an open state. A support plate 12 is provided on the outer shell 1. When the drainage trough is installed, the support plate 12 supports the drainage trough as a whole. A cavity for accommodating the inner sleeve 2 is provided in the outer shell 1. A connecting portion 13 is provided at the bottom of the outer shell 1. The connecting portion 13 is tubular and is used to be connected to a pipeline. The connecting portion 13 extends in the opposite direction to a limiting cylinder 14. A water storage chamber is provided on the inner sleeve 2, and a sleeve 21 matching the limiting cylinder 14 is provided at the bottom of the water storage chamber. The sleeve 21 can be sleeved on the limiting cylinder 14, and the limiting cylinder 14 plays a positioning role for the sleeve 21, which can effectively prevent the inner sleeve 2 from shaking during operation. Of course, a limiting groove can be added to the sleeve 21, and a limiting strip can be added to the limiting cylinder 14. Under the joint action of the limiting groove and the limiting strip, the inner sleeve 2 can be prevented from rotating, thereby ensuring its stability during operation. At the same time, a drainage hood 22 is provided on the top of the sleeve 21, and the drainage hood 22 can be fixedly connected to the sleeve 21 through a support rod.
[0019] When the drainage trough is in use, rainwater gathers on the bottom surface and flows into the drainage trough. When the rainwater passes through the first filter plate 11, larger debris cannot pass through, so that larger debris can be prevented from entering the drainage trough, thereby ensuring the drainage effect of the drainage trough. After the rainwater enters the drainage trough, the rainwater also carries mud and sand. The drainage cover 22 on the top of the sleeve 21 plays a role in draining the rainwater, thereby preventing the rainwater carrying mud and sand from directly entering the sleeve 21. At the same time, the sleeve 21 is extended upward, and a sedimentation area is formed at the entrance of the sleeve 21 and the bottom of the water storage chamber. The mud and sand are deposited in the sedimentation area under the action of gravity, thereby reducing the amount of mud and sand entering the sleeve 21. When the mud and sand that need to be deposited are cleaned out of the drainage trough, the inner sleeve 2 can be directly taken out for cleaning.
[0020] For the improvement of the above embodiment, Figure 3 As shown, a spoiler 23 is provided on the sleeve 21, and the spoiler 23 is located below the drainage cover 22. The flowing rainwater may bring the deposited silt to the entrance of the sleeve 21. The spoiler 23 blocks the rainwater and can effectively prevent the water flow from bringing the silt into the entrance of the sleeve 21.
[0021] In addition, in order to further improve the filtering effect of the drainage trough, such as Figure 3 As shown, a second filter plate 24 can be provided on the sleeve 21 at the same time, and the rainwater can be filtered for a second time through the second filter plate 24 to achieve a better filtering effect. When the second filter plate 24 is set, a threaded boss can be provided on the second filter plate 24, and the drainage cover 22 can be screwed on the second filter plate 24 through the boss. In this way, the drainage cover 22 can be removed to clean the second filter plate 24.
[0022] Based on further improvements to the utility model, such as Figure 1 As shown, a limiting platform 15 is provided on the housing 1 , and the first filter plate 11 can be embedded in the limiting platform 15 , so that the first filter plate 11 is not higher than the support plate 12 , so that rainwater can pass through the first filter plate 11 easily.
[0023] At the same time, if Figure 1 As shown, a lock hole 112 is provided on the first filter plate 11, and a sliding lock 16 is provided on the support plate 12. The lock head of the sliding lock 16 can be inserted into the lock hole 112. In this way, when the first filter plate 11 is closed, the first filter plate 11 will not be impacted open by the water flow.
[0024] In addition, the outer shell 1 and the inner shell 2 are funnel-shaped, which makes it easier for mud and sand to settle in the sedimentation area.
[0025] Of course, in order to improve the stability of the inner sleeve 2 during operation, Figure 1 As shown, a pressing piece 111 is provided on the first filter plate 11. Here, the pressing piece 111 can be provided with a rubber gasket. When the first filter plate 11 is closed, the pressing piece 111 abuts against the top of the inner sleeve 2 to ensure that the inner sleeve 2 does not shake.
[0026] And, if Figure 1 As shown, a handle 25 is pivotally connected to the inner sleeve 2, so that the inner sleeve 2 can be easily taken out. At the same time, a concave cavity for accommodating the handle 25 is provided at the top of the inner sleeve 2. When the inner sleeve 2 is placed in the outer shell 1, the handle 25 can be rotated into the concave cavity.
[0027] The above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
