Description

Technical Field

[0001] The utility model belongs to the technical field of road drainage, and in particular relates to an automatic drainage device for accumulated water. Background Art

[0002] In order to facilitate passage when it rains, the road surface is mostly slightly raised in the middle, and the two sides close to the curbstone are slightly lower than the middle of the road surface. This is to ensure that there is no water accumulation in the driving position in the middle part of the road surface. Existing ground drainage relies on drains set up on the roadside and sewer pipes for drainage. At present, edge drainage systems mostly adopt structural forms, through longitudinal drainage pipes or drainage grooves and horizontal outlet pipes, and finally connected to the municipal drainage pipe. With this road drainage method, the drainage asphalt pavement only solves the problem of no water accumulation on the surface on rainy days, making driving safer; however, this method has a large amount of water on the road surface when the rainfall is heavy, and the water pressure inside the municipal drainage pipe is high, and then the water inside the drainage pipe may flow back to the road surface, causing deep water on the road surface and inconvenience in traffic. Utility Model Content

[0003] The utility model aims to provide an automatic drainage device for accumulated water, which can automatically discharge accumulated water on the road surface into a drainage ditch below the road surface. At the same time, when the amount of accumulated water on the road surface is large, it can prevent the water in the internal drainage ditch from flowing back to the road surface, thereby reducing accumulated water on the road surface.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic drainage device for accumulated water, comprising a ditch cover installed on a road surface, a drainage ditch is provided below the ditch cover, a guide assembly is installed on the side of the drainage ditch, a groove is provided inside the drainage ditch, a collecting channel is provided below the groove, the drainage ditch is connected with the collecting channel through the groove, a diversion ditch is provided on one side of the drainage ditch, the guide assembly comprises a support rod fixed on the side of the drainage ditch, two support rods are symmetrically arranged, a rotating shaft is rotatably connected between the two support rods, and a plurality of guide plates are fixed on the side of the rotating shaft.

[0005] Furthermore, a through slot is provided at the bottom of the groove, a baffle is rotatably connected inside the through slot, and the other end of the baffle abuts against the bottom of the through slot.

[0006] Furthermore, the baffle is in an arc shape, and its protruding side is arranged toward the drainage ditch side.

[0007] Furthermore, a fixing plate is fixed to the end of the support rod facing the inner wall of the drainage ditch, two fixing plates are symmetrically arranged about the middle of the support rod, a fixing cone is inserted into the fixing plate, and a plurality of protrusions are arranged on the side of the fixing cone.

[0008] Furthermore, a ball bearing is embedded in the support rod near the end of the rotating shaft, and the two ends of the support rod rotate inside the two ball bearings.

[0009] Furthermore, the guide vanes are provided in a plurality along the axis direction of the rotating shaft, and the installation positions of the guide vanes correspond to the grille positions of the trench cover plate.

[0010] Furthermore, the side surface of the diversion ditch is inclined, and the connection between the diversion ditch and the drainage ditch is rounded.

[0011] The beneficial effects of the utility model are:

[0012] The device can automatically discharge the accumulated water on the road surface into the drainage ditch below the road surface. At the same time, a groove is set inside the drainage ditch. There is a rotatable baffle inside the groove at the bottom of the groove. The water is discharged into the collecting channel through the baffle. When the amount of accumulated water on the road surface is large, it can impact the bottom of the baffle. The baffle fits on the bottom of the groove and closes the groove, which can prevent the water inside the drainage ditch from flowing back to the road surface and reduce the accumulated water on the road surface. 2. Support rods are set inside the drainage ditch. The rotating shaft is rotatably connected between the two support rods. The guide vane is fixed outside the rotating shaft, which can entangle and rotate the dirt inside the accumulated water. Under the action of centrifugal force, the dirt and accumulated water are discharged into the diversion ditch to reduce the drainage pressure of the drainage ditch and further improve the drainage capacity of the drainage ditch.

[0017] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0018] Please also refer to Figures 1 to 3 The automatic water discharge device of the utility model embodiment will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1As shown, the automatic drainage device for accumulated water includes a ditch cover 1 installed on the road surface, a drainage ditch 2 is provided below the ditch cover 1, a guide assembly is installed on the side of the drainage ditch 2, a groove 3 is provided inside the drainage ditch 2, a collecting channel 4 is provided below the groove 3, the drainage ditch 2 is connected with the collecting channel 4 through the groove 3, a diversion ditch 5 is provided on one side of the drainage ditch 2, and the guide assembly includes a support rod 6 fixed to the side of the drainage ditch 2, two support rods 6 are symmetrically arranged, a rotating shaft 7 is rotatably connected between the two support rods 6, and a plurality of guide plates 8 are fixed to the side of the rotating shaft 7.

[0020] In this embodiment, a drainage ditch 2 is provided under each ditch cover 1 on the road surface. The drainage ditches 2 are interconnected, and one end of the collecting channel 4 discharges into the river.

[0021] A through slot 10 is provided at the bottom of the groove 3 , and a baffle 9 is rotatably connected inside the through slot 10 , with the other end of the baffle 9 abutting against the bottom of the through slot 10 .

[0022] In addition, the baffle plate 9 is in an arc shape, and its protruding side is disposed toward the drainage ditch 2 side.

[0023] After the water on the road surface enters the drainage ditch 2 along the ditch cover 1, the water flow hits the baffle 9, driving the baffle 9 to rotate toward the collecting channel 4, so that the water inside the drainage ditch 2 can be quickly discharged into the collecting channel 4. Since multiple ditch covers 1 are arranged on the road surface, the water on the road surface can be quickly discharged into the collecting channel 4. When the rainfall is heavy, the water flow inside the collecting channel 4 is large, hitting the bottom of the baffle 9, and then as the water flow inside the drainage ditch 2 hits the surface of the baffle 9, there is a balance between the two, so that continuous drainage can be achieved. If the amount of water inside the collecting channel 4 is too large, it can hit the baffle 9 to cover the through groove 10 to prevent water from flowing back to the road surface.

[0024] At the same time, a support rod 6 is arranged inside the drainage ditch 2, wherein a fixing plate 11 is fixed to the inner wall end of the support rod 6 facing the drainage ditch 2, two fixing plates 11 are symmetrically arranged about the middle of the support rod 6, a fixing cone 12 is inserted inside the fixing plate 11, and a plurality of protrusions are arranged on the side of the fixing cone 12.

[0025] A ball bearing 13 is embedded at the end of the support rod 6 close to the rotating shaft 7 , and both ends of the support rod 6 rotate inside the two ball bearings 13 .

[0026] A plurality of guide vanes 8 are provided along the axis direction of the rotating shaft 7 , and the installation positions of the guide vanes 8 correspond to the grid positions of the trench cover 1 .

[0027] After the water flows in along the ditch cover 1, it can flow down along the grille of the hook cover and hit the guide plate 8, which then rotates together with the rotating shaft 7. The water flow can be dispersed by the rotation of the guide plate 8, and the dirt therein can be driven to rotate. Under the action of centrifugal force, the dirt is driven to the inside of the diversion ditch 5, thereby avoiding clogging the drainage ditch 2. At the same time, when the rainfall is heavy, the water can be diverted to increase the drainage efficiency.

[0028] At the same time, the side surface of the diverter ditch 5 is inclined, and the connection between the diverter ditch 5 and the drainage ditch 2 is rounded to better deposit dirt.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
