Detailed Description

The present invention will be further explained below.

The embodiment is as follows: as shown in fig. 1-4, an anti-blocking type drainage wellhead comprises a drainage wellhead 1, a manhole cover 2 and a drainage anti-blocking structure, wherein the manhole cover 2 is circular and is fastened at the upper end of the drainage wellhead 1, the drainage anti-blocking structure is fixedly installed on the inner wall of the drainage wellhead 1 and is located below the manhole cover 2, a plurality of first drainage holes 201 which are uniformly arranged are formed in the middle of the manhole cover 2, threaded connection holes 202 are formed in the left side and the right side of the manhole cover 2, the threaded connection holes 202 are used for detachably connecting first connection rods 7, internal threads are formed in the outer wall of the first connection rods 7, external threads which are matched with the internal threads are formed in the threaded connection holes 202, the manhole cover 2 is connected with the drainage anti-blocking structure through the first connection rods 7, a drainage box 6 is connected to the lower end face of the manhole cover 2 through a steel wire rope 5, a plurality of second drainage holes 601 are formed in the bottom of the drainage box 6, the drainage flow rate of the second drainage holes 601 is smaller than that of the first drainage holes 201, a second connection rod 8 is arranged on the side face of the drainage box 6, and is connected with the drainage anti-blocking structure; can open well lid 2 and be used for improving the drainage flow of drainage well head 1 through well lid 2, the cooperation of stifled structure of drainage and drainage box 6, in time discharge ponding.

The drainage anti-blocking structure comprises two steel bar supports 3, two rotary supporting plates 4, a first connecting column 10 and a second connecting column 11, wherein the two steel bar supports 3 are symmetrically arranged on the inner walls of the left side and the right side of a drainage wellhead 1, the two steel bar supports 3 are rotatably connected with the rotary supporting plates 4 through bearings 15, two ends of each rotary supporting plate 4 are respectively hinged with the first connecting column 10 and the second connecting column 11, namely, the first connecting column 10, the rotary supporting plates 4 and the second connecting column 11 form a lever structure, the first connecting column 10 is connected with a well lid 2 through a first connecting rod 7, the second connecting column 11 is connected with a drainage box 6 through a second connecting rod 8, and when no accumulated water exists in the drainage box 6, the drainage box 6 is not heavy enough to pry the well lid 2, so that when the drainage box 6 is filled with accumulated water and the weight is increased, the drainage box 6 can pry the well lid 2 under the action of the lever structure, open the well lid 2 and improve the drainage rate;

preferably, the vertical distance from the hinge point of the first connecting column 10 and the rotary support plate 4 to the steel bar support 3 is three times the vertical distance from the hinge point of the second connecting column 10 and the rotary support plate 4 to the steel bar support 3, wherein when the first connecting column 10 is parallel to the drainage wellhead 1, the first connecting column 10 is directly opposite to the threaded connection hole 202, that is, the threaded connection hole 202 is located right above the hinge point of the first connecting column 10 and the rotary support plate 4.

Specifically, the lower extreme of first spliced pole 10 is articulated with rotatory backup pad 4, and first connecting groove 12 has been seted up to the upper end of first spliced pole 10, the inner wall of first connecting groove 11 seted up with the internal thread of the external screw thread adaptation of head rod 7 outer wall, the lower extreme of second spliced pole 11 is articulated with rotatory backup pad 4, and second spread groove 13 has been seted up to the upper end of second spliced pole 11, second spread groove 13 with second connecting rod 8 adaptation, second connecting rod 8 can insert in second spread groove 13 and provide the supporting role for water drainage tank 6 promptly.

Specifically, the anti-blocking structure of drainage still includes uide bushing block 9, uide bushing block 9 fixed mounting is in on drainage well head 1's the inner wall to be located the top of reinforcing bar pillar 3, the through-hole has been seted up at the middle part of uide bushing block 9, and establish through the through-hole cover on first spliced pole 10 and the second spliced pole 11, first spliced pole 10 also can slide in the through-hole with second spliced pole 11 simultaneously, can let through uide bushing block 9 first spliced pole 10 and second spliced pole 11 are in vertical state always, are convenient for to the installation of well lid 2 and drain box 6.

Specifically, the upper ends of the first connecting column 10 and the second connecting column 11 are respectively provided with a blocking block 14, and the first connecting column 10 and the second connecting column 11 can be prevented from completely sliding out of the through hole through the cooperation of the blocking blocks 14 and the guide sleeve blocks 9.

The working principle is as follows:

during the installation, accomplish earlier the installation of drainage box 6, insert second connecting rod 7 in second spread groove 13 earlier promptly, then detain well lid 2 and put on drainage well head 1, later accomplish the installation of well lid 2 in precession threaded connection hole 202 and the first spread groove 12 with first connecting rod 7 to wire rope 5's length is greater than the distance of terminal surface under drainage box 6 top surface to well lid 2, that is to say, wire rope 5 is in lax state this moment.

When the ponding on road surface is in normal condition, for example when it is rainy or rainy in the short time, because the flow of first drain hole 201 is greater than the flow of second drain hole 601, consequently can ponding gradually in the drain tank 6, but behind the ponding on road surface flows into drain tank 6 completely, drain tank 6 has not been filled completely yet, so drain tank 6 and the weight of ponding are not enough to jack up well lid 2 through lever structure, and then realize the normal drainage function of well lid 2.

When the road area water is large, for example, heavy rain or long-time medium rain, when the accumulated water on the road surface does not completely flow into the drainage box 6, the drainage box 6 is filled with the accumulated water, the weight of the drainage box 6 and the accumulated water is enough to jack up the well lid 2 through a lever structure, so that the accumulated water flows into the drainage well mouth 1 from the side edge of the well lid 2, part of the accumulated water continuously flows into the drainage box 6 under the action of high flow velocity to keep the weight of the drainage box 6, so that the well lid 2 can be always jacked up, meanwhile, the second connecting column 11 is prevented from sliding out of the guide block 9 under the blocking action of the blocking block 14, the steel wire rope is in a tightening state, after the road area water flows out, the accumulated water in the drainage box 6 is gradually reduced, and the well lid 2 is buckled again; through the anti-blocking structure of drainage, the drainage flow can be automatically and rapidly improved, the accumulated water on the road surface can be timely discharged, and the accumulated water is prevented from being accumulated and piled up.

The principle and the implementation of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understand the method and the core idea of the present invention; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
