Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drainage, and in particular relates to a subway tunnel drainage device. Background Art
[0002] Subway is a fast, high-capacity, electric-powered rail transit system built in cities. Trains run on fully enclosed lines. Lines in the central urban area are basically set up in underground tunnels, and lines outside the central urban area are generally set up on viaducts or on the ground. Subway is a high-density, high-capacity urban rail transit system that covers all kinds of underground and above-ground road rights in urban areas. Since the tunnel is set up underground, a large amount of water such as ground water accumulation and underground seepage water will gather in the tunnel on rainy days. If the water is not cleared in time, it will affect the use of the tunnel. Therefore, drainage devices are usually installed in the tunnel.
[0003] At present, when the drainage device is draining water, due to the impact of the water flow, some sand and flocs will be discharged along with the water flow, resulting in the accumulation of some sand and flocs inside the drainage pipe and the device. The long-term accumulation is likely to clog the pipe, resulting in abnormal drainage. The existing drainage device usually filters the water flow through a filter plate. It is cumbersome to replace or clean the filter plate. It is necessary to lift up the cover plate first, and then lift up the filter plate for replacement, which not only makes the replacement efficiency low, but also increases the workload of the staff.
[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content
[0005] The utility model aims to provide a subway tunnel drainage device, which solves the problems of low efficiency and heavy workload in the existing subway tunnel drainage device when replacing or cleaning the filter plate.
[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:
[0007] A subway tunnel drainage device, comprising a drainage trough, a drainage pipe located at the bottom of the drainage trough, a cover plate located on the drainage trough and a filter plate located in the drainage trough, the drainage trough being connected to the drainage pipe through a connecting pipe, the filter plate being detachably connected to the bottom of the cover plate, the bottom of the cover plate being rotatably connected to a plurality of connecting rods arranged in a rectangular array, the filter plate being formed with through holes slidably sleeved on the connecting rods, the side walls of the connecting rods being further formed with bearing blocks, and the filter plate being formed with a clearance opening for the bearing blocks to pass through; the left and right ends of the cover plate are further provided with a clamping assembly, the clamping assembly comprising a clamping plate and a first return spring, the ends of the left and right ends of the cover plate being formed with a slide groove, the clamping plate being slidably installed in the slide groove, one end of the first return spring being fixedly connected to the inner side of the clamping plate, and the other end being fixedly connected to the inner side wall of the slide groove; the inner side wall of the drainage trough is formed with a bearing step and a plug-in slot for placing the cover plate, the plug-in slot being located on the side of the bearing step away from the cover plate; the top of the clamping plate is further formed with a clamping slot.
[0008] Furthermore, a baffle is slidably provided in the slot, and a second return spring is provided at the bottom of the baffle, one end of the second return spring is fixedly connected to the bottom of the baffle, and the other end is fixedly connected to the inner bottom wall of the slot. By clamping the baffle on the slot, mud and sand can be prevented from rushing into the slot and causing the slot to be blocked. In addition, when the filter plate needs to be cleaned or replaced, the baffle can be automatically reset by the second return spring after the baffle is pressed down.
[0009] Furthermore, the middle of the filter plate is concave downward to form a spherical sand trap, and the sand trap is formed with a plurality of water filtering holes; the bottom of the cover plate is formed with a diversion channel, and the diversion channel is coaxially arranged with the sand trap, and the inner diameter of the diversion channel gradually decreases from top to bottom. The water flow entering the drainage trough can be firstly merged into the sand trap through the diversion channel, and the sand trap is used to intercept the sediment in the water flow, thereby reducing the sediment entering the drainage trough.
[0010] Furthermore, a mesh plate with an upwardly arched spherical surface is provided on the top of the filter plate; an annular guide ring is formed on the outer wall of the filter plate, and the outer diameter of the guide ring gradually increases from top to bottom. The mesh plate can prevent some floccules from entering the sand trough and causing the filtration holes in the sand trough to be blocked.
[0011] Furthermore, the bottom of the drainage trough is formed with a plurality of inclined guide surfaces, the lower ends of the plurality of guide surfaces converge to the top of the connecting pipe, and the upper surface of the guide surface is also formed with a plurality of interception rods. By setting the bottom of the drainage trough as an inclined guide surface, the water flow can be smoothly merged into the drainage pipe, and by setting the interception rods on the guide surface, some flocs can be intercepted to prevent the flocs from entering the drainage pipe and causing clogging of the drainage pipe.
[0012] After adopting the above structure, the utility model involves a subway tunnel drainage device. Compared with the prior art, the present invention has a plurality of connecting rods rotatably installed at the bottom of the cover plate, and the filter plate is slidably mounted on the connecting rods. When the filter plate needs to be replaced or cleaned, it is only necessary to lift the cover plate upward to drive the filter plate to move upward together, which is more efficient and reduces the workload. In addition, when separating the filter plate from the cover plate, it is only necessary to rotate the connecting rod so that the clearance port corresponds to the bearing block, so that the filter plate can be separated from the connecting rod, which is very convenient. In addition, the cover plate can be quickly clamped on the drainage trough or the cover plate can be quickly removed from the drainage trough through the clamping assembly.

The hole 41 is connected. When the filter plate 4 is installed, the connecting rod 31 is first rotated so that the bearing block 311 faces outward and is aligned with the clearance opening 42. At this time, the connecting rod 31 can be passed through the through hole 41, and then the connecting rod 31 is rotated again so that the bearing block 311 is supported on the bottom of the connecting plate; the left and right ends of the cover plate 3 are also provided with a clamping assembly 5, the clamping assembly 5 includes a clamping plate 51 and a first return spring 52, and the ends of the left and right ends of the cover plate 3 are formed with a slide groove 32, the clamping plate 51 is slidably installed in the slide groove 32, one end of the first return spring 52 is fixedly connected to the inner side of the clamping plate 51, and the other end is fixedly connected to the inner side wall of the slide groove 32; the inner side wall of the drainage groove 1 is formed with a bearing step 11 and a plug-in groove 12 for placing the cover plate 3, and the plug-in groove 12 is located on the side of the bearing step 11 away from the cover plate 3; the top of the clamping plate 51 is also formed with a clamping groove 511.
