Description

Technical Field

[0001] The utility model belongs to the technical field of municipal drainage, and in particular relates to a municipal drainage ditch manhole cover. Background Art

[0002] Urban road drainage refers to the measures taken to remove precipitation on the urban road surface. Usually, the road water flows into the drainage ditch according to the slope of the road surface, and then is discharged from the outlet of the drainage ditch to nearby rivers, lakes, seas and other water bodies. The drainage of urban road surface water should be fast and smooth, and no water should accumulate or form a water film on the road surface to affect driving;

[0003] Most of the existing technologies use drainage ditches for road drainage, and drainage is drained by opening drainage holes on the drainage ditch covers. Multiple drainage ditches are set up on urban roads. When there is water on the road surface, the accumulated water is made to flow into the drainage ditch through the design of the terrain. When there is too much water on the road surface, the drainage speed of the drainage ditch is slow, resulting in the water on the road surface not being discharged immediately. Excessive water accumulation will affect driving and people's normal travel safety, and it is necessary to increase the drainage rate. Most methods to increase the drainage rate are to increase the number of drainage holes, or to remove the drainage manhole cover to increase the drainage efficiency. Opening too many drainage holes on the manhole cover can easily affect the driving comfort of the vehicle and cause the vehicle to be bumpy. The removal of the manhole cover requires manual removal, which is time-consuming and laborious. Utility Model Content

[0030] like Figures 1 to 5 A municipal drainage ditch manhole cover is shown, in which a drainage pipe 1 is arranged in the drainage ditch, and the manhole cover includes a base 2, a cover body 4 and a discharge column 5. The base 2 is laid on the ground, and the top of the base 2 is flush with the ground. A transition pipe 3 is arranged between the base 2 and the drainage pipe 1, and a cover-carrying groove 21 is provided on the inner side of the base 2. The cover body 4 is embedded and installed in the cover-carrying groove 21, and the top surface of the cover body 4 is flush with the ground. The cover body 4 is provided with a plurality of drainage holes 41 connected to the drainage pipe 1 for water flow to pass through. The discharge column 5 is fixed to the middle position of the drainage pipe 1 through a bracket 6, and a spiral guide plate 51 is installed on the discharge column 5. A receiving groove 52 is provided on the top of the discharge column 5, and a push rod mechanism 53 is installed in the receiving groove 52, so as to automatically lift the cover body 4, realize emergency drainage, and avoid water accumulation on the road. A waterproof cover plate 54 is provided above the receiving groove 52 to block the receiving groove 52, so as to protect the push rod mechanism 53.

[0031] In one embodiment, first, a drainage pipe 1 is installed in a drainage ditch below the ground, and the base 2 and the drainage pipe 1 are connected through a transition pipe 3. The base 2 is placed in a foundation pit dug in advance, and the top of the base 2 is flush with the road surface. The base 2 is set to protect the road surface and the cover body 4. The push rod mechanism 53 is installed in the receiving groove 52 of the discharge column 5, and then the receiving groove 52 is blocked with a waterproof cover plate 54 to play a waterproof protection role for the push rod mechanism 53. Finally, the cover plate is covered in the cover loading groove 21 to achieve the installation of the manhole cover.

[0032] During normal use, sewage is collected above the cover body 4 through the road surface and flows into the drain pipe 1 through the drainage holes 41. In order to reduce the impact of the cover body 4 on the driving of the vehicle, a small number of drainage holes 41 are provided on the cover body 4, which can only maintain daily drainage. When the amount of rainwater in the city is large, a large amount of sewage flows into the drain pipe 1 through the drainage holes 41. A large amount of sewage flows rapidly in the drain pipe 1 under the action of the spiral guide plate 51, and can drive the spiral guide plate 51 to rotate relative to the axis of the discharge column 5. When the speed meter on the discharge column 5 detects that the rotation speed of the spiral guide plate 51 reaches the set value, that is, when the rainwater flow reaches the set flow, the controller reads the value fed back by the speed meter and sends a start signal to the push rod mechanism 53. The rod section of the push rod mechanism 53 is extended to automatically push the cover plate out of the cover slot 21, so as to realize the disassembly of the cover plate, thereby facilitating a large amount of sewage or rainwater to flow into the drain pipe 1.

[0033] It should be noted that the push rod mechanism 53 is an existing telescopic rod device, the push rod mechanism 53 adopts a waterproof design, and has an internal power supply or is connected to an external power supply through a power cord.

[0034] Preferably, the drain manhole cover also includes a controller, which is connected to the push rod mechanism 53 by signal to realize remote control of each push rod mechanism 53. The waterproof cover plate 54 is adhered to the top of the push rod mechanism 53, and the diameter of the waterproof cover plate 54 is larger than the aperture of the drainage hole 41, so that the waterproof cover plate 54 is fixedly installed.

[0035] In one embodiment, in order to prevent the waterproof cover plate 54 from falling into the drain pipe 1 when the push rod mechanism 53 pushes out the cover body 4, the waterproof cover plate 54 is adhered and fixed to the top of the push rod mechanism 53, so that when the push rod mechanism 53 is located in the receiving groove 52, the waterproof cover plate 54 can block the receiving groove 52; when the push rod mechanism 53 is pushed out, the waterproof cover plate 54 is fixed to the top of the push rod mechanism 53 to prevent the waterproof cover plate 54 from being lost.

[0036] Preferably, the spiral guide plate 51 is sleeved on the drainage column 5, and the spiral guide plate 51 can rotate around the drainage column 5, so that the gas in the drainage ditch can flow out to the outside, and the external sewage can flow smoothly into the drainage pipe 1.

[0037] Preferably, a tachometer is installed on the discharge column 5, and the tachometer can measure the rotation speed of the spiral guide plate 51, and the tachometer is connected to the controller data. The tachometer is used to indirectly measure the speed of the water flow in the drainage pipe 1.

[0038] Preferably, a sealing rubber ring is further provided at the abutment point between the waterproof cover plate 54 and the drain column 5 to improve the sealing performance of the waterproof cover plate 54 to the receiving groove 52 .

[0039] Preferably, the bracket 6 on the top of the drainage column 5 is fixed to the base 2 in a radial shape, and the bracket 6 can prevent foreign debris from flowing into the drainage pipe 1 to a certain extent.

[0040] Preferably, the aperture of the transition pipe 3 gradually decreases from the base 2 toward the drain pipe 1, and a larger base 2 can be used to facilitate the convergence of water flow to the drain pipe 1. A supporting rib 31 protrudes from the inner side of the transition pipe 3 to increase the supporting strength of the transition pipe 3.

[0041] Preferably, a magnetic part is provided on the top of the waterproof cover plate 54, and the waterproof cover plate 54 can be attracted to the bottom of the cover body 4 to achieve attraction and fixation of the waterproof cover plate 54 and the cover body 4, thereby preventing the waterproof cover plate 54 from being lost or flowing into the drain pipe 1.

[0042] In one embodiment, the waterproof cover plate 54 is sucked into the bottom of the cover body 4. When the cover body 4 covers the cover loading groove 21, the waterproof cover plate 54 can block the receiving groove 52. When the cover body 4 is pushed out by the push rod mechanism 53, the waterproof cover plate 54 is sucked into the cover body 4 to prevent the cover body 4 from being lost.

[0043] Preferably, the inner sides of the cover body 4 and the base 2 are coated with a Teflon coating. The Teflon coating has a low friction coefficient and good non-stick properties, which prevents garbage and other debris from being attached to the cover body 4 and the base 2.

[0044] Preferably, the drainage hole 41 is in the shape of an elongated strip, and a plurality of support rods 42 are installed in the drainage hole 41, and the support rods 42 are evenly distributed along the extension direction of the drainage hole 41.
