[0026] Embodiments
[0027] With reference to Figures 1-5 The utility model provides a technical scheme: prevent falling support grating, including bottom frame 1 and prevent falling mechanism 3, and on bottom frame 1 rotatory installation cover plate 2, prevent falling mechanism 3 includes annular sleeve 31, annular sleeve 31 is equipped with on cover plate 2 with cover plate 2 rotatory connection, support rod 32 rotatory installation is in annular sleeve 31, and is installed with screw column 321 at the bottom of support rod 32, and the position of positioning plate 33 stable installation is in the inner side of bottom frame 1, and the upper surface of positioning plate 33 is equipped with through -hole 331.
[0028] In a preferred embodiment, the opening is provided on the bottom frame 1, and the rotating block 4 is rotatably installed at the position of the opening. The rotating block 4 is fixedly connected with the cover plate 2. In order to meet the use, the bottom frame 1 and the cover plate 2 are arranged in a rotatable connection. When in actual use, the cover plate 2 can be opened, so that water can quickly pass through the inside of the bottom frame 1 and enter the well. When the cover plate 2 does not need to be rotated, the cover plate 2 can be covered on the bottom frame 1 and be flush with the road surface, so that the device can be normally used.
[0029] In a preferred embodiment, the cover plate 2 is provided with a plurality of water inlet holes 5, which are uniformly arranged on the upper surface of the cover plate 2. The device is provided with a plurality of water inlet holes 5 on the cover plate 2, so that the water on the road surface can flow into the well through the water inlet holes 5 when in normal use. At the same time, it can also avoid pedestrians from falling into the well, thereby playing a role in protecting pedestrians.
[0030] In a preferred embodiment, the inside of the bottom frame 1 is hollow, and the inside of the water inlet hole 5 is communicated with the inside of the bottom frame 1 for drainage. The device is convenient for draining the road surface. After the rainwater flows into the inside of the water inlet hole 5, it will enter the inside of the bottom frame 1 again. The rainwater passing through the inside of the bottom frame 1 will enter the well, so as to treat the rainwater.
[0031] The device uses the support rod 32 to support the cover plate 2, and the support rod 32 needs to be limited, so the baffle 6 is stably installed at the upper end of the threaded column 321, the baffle 6 is arranged above the positioning plate 33, and the support rod 32 is limited. In actual use, the threaded column 321 extends into the through hole 331, at this time the baffle 6 is attached to the positioning plate 33, so that the support rod 32 cannot continue to move, and the support rod 32 is limited, thereby stably supporting the use of the cover plate 2.
[0032] In order to facilitate the support rod 32 to extend into the through hole 331, and also facilitate the support rod 32 to be taken out from the through hole 331, the diameter of the through hole 331 is greater than the diameter of the threaded column 321 by 5 mm, the threaded column 321 is inserted into the through hole 331, the threaded column 321 is screwed with the nut 7, and the nut 7 is arranged below the positioning plate 33. The threaded column 321 is positioned, the diameter of the through hole 331 is greater than the diameter of the threaded column 321, so as to leave enough space for the threaded column 331 to move, facilitate the support rod 32 to be limited, and the nut 7 is screwed on the threaded column 321. The support rod 32 can be stably used.
[0033] Specifically, the working process or working principle of the anti-falling support grating is: in the rainy season, if it rains heavily, it is difficult to discharge rainwater in time only by relying on the water inlet hole of the grating, so the grating cover is opened in heavy rain to facilitate the rapid flow of rainwater into the well, and the rainwater on the road surface is discharged. But in actual operation, after the grating cover is opened, under the impact of rainwater, the cover will be closed, reducing the speed of rainwater entering the well and reducing the drainage effect, so the device is designed to solve the problem.
[0034] The device is provided with a rotatable support rod 32 on the cover plate 2, one end of the support rod 32 extends into the positioning hole, and the extended part is screwed with the nut 7, so as to position the support rod 32, thereby supporting the rotated cover plate 2, and the device can be stably used. The specific operation is that the device is installed at the well mouth, when the rainwater is heavy, the cover plate 2 needs to be opened, and the bottom frame 1 is completely exposed, so that the rainwater flows into the well quickly and drains the road surface in time.
[0035] In actual use, in order to prevent the opened cover plate 2 from returning to the original position under the impact of rainwater, after the cover plate 2 is opened, the support rod 32 is adjusted, one end of the support rod 32 is moved to the position of the positioning plate 33, the threaded column 321 penetrates through the inside of the through hole 331, and then the nut 7 is screwed on the threaded column 321 from the position below the positioning plate 33. In this way, the support rod 32 is positioned, the cover plate 2 is stably supported by the support rod 32, the cover plate 2 will not fall down, and the use is satisfied.
[0036] When the cover plate 2 is not needed to rotate, the nut 7 is unscrewed, and one end of the support rod 32 is taken out from the inside of the positioning plate 33, so that the cover plate 2 can normally rotate. In order to prevent the nut 7 from being lost, the nut 7 can be screwed on the threaded column 321 again, and then the cover plate 2 is covered on the bottom frame 1. At this time, the support rod 32 will naturally droop and droop into the well, so that the cover plate 2 can be stably covered on the bottom frame 1, and the device can be normally used.
