Description

a drainage manhole cover

technical field

The utility model relates to the technical field of drainage well covers, in particular to a drainage well cover which can prevent sundries from entering sewers and can discharge water according to the water volume.

Background technique

On city streets, manhole covers play an important role in dredging rainwater from the streets. Especially in the summer of our country, there is a lot of rain and a large amount of rainfall. If the precipitation on the streets is not removed in time, it will have a negative impact on the traffic in the city. Some of the existing drainage well covers are circular metal parts with round holes through which rainwater leaks. Due to the limited size of the round holes, the drainage efficiency is low; some are welded by several steel bars. The drainage well covers of this structure , although the rapid discharge of rainwater can be achieved, but garbage such as branches, leaves and plastic bags on the street can easily enter the sewer and cause peculiar smell. Therefore, be badly in need of a kind of drainage well cover that can avoid that rubbish etc. enter in the sewer through the drainage well cover, and can discharge water according to the water volume size again.

Utility model content

The purpose of the utility model is to provide a drainage well cover, which is used to solve the problem that the existing drainage well cover cannot discharge water according to the water volume, and at the same time prevent garbage from entering the sewer.

The beneficial effects of the utility model are: the utility model provides a drainage well cover, the rainwater leaks through the leakage hole on the garbage baffle, and the larger garbage is blocked on the garbage baffle, preventing a large amount of garbage from entering the sewer The rot caused by it, thus avoiding the emission of peculiar smell. When the amount of rainwater is large, under the action of rainwater and the gravity of the restrictor plate itself, the free end of the restrictor plate swings downward, making the restrictor plate in a tilted state. At this time, the rainwater leaks through the leak hole and then passes through the restrictor plate. Flowing down allows a large amount of rainwater to quickly flow into the sewer. According to the different amount of rainwater, the inclination angle of the restrictor plate is different, so as to adapt to the discharge of rainwater with different weight and volume.

Detailed ways

As shown in Figures 1 to 11, the utility model includes a support frame 1, a garbage baffle 2 and a flow limiting plate 3, and the utility model will be described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 4, the support frame 1 is a square hollow metal piece with two long sides and two short sides, which can be welded and fixed by four metal rods with a rectangular cross section, or can be fixed by wires. Obtained by cutting a rectangular sheet of metal. As shown in Figure 6, a groove 11 is provided at the bottom of the support frame, and the length dimension of the groove is between the length dimension of the inner chamber of the support frame and the length dimension of the shape of the support frame; the width dimension of the groove is between Between the width dimension of the inner cavity of the support frame and the width dimension of the outer shape of the support frame. The bottom of one of the short sides is provided with some spring installation holes 12, as shown in Figure 5, a partition 13 located in the inner cavity of the support frame is provided on the side of the other short side, and the partition is a strip-shaped metal plate. And the separator is located between the top surface and the bottom surface of the supporting frame. A garbage baffle 2 is installed on the short side hinged 4 of the support frame provided with the spring mounting hole, the garbage baffle is a rectangular metal plate, and the installation end of the garbage baffle is hinged with the short side of the spring mounting hole on the support frame , the free end of the garbage baffle rests on the partition. The upper surface of the free end of the garbage baffle is provided with a lug 22, and the lug is provided with a circular hole. When the garbage baffle needs to be opened, as shown in Figure 10, hook the lug and pull upwards by a hook. The garbage baffle is provided with some leaking holes 21 arranged in a matrix form, and the leaking holes can be elongated holes, round holes, square holes, etc. Rainwater can leak down through the weep hole, and rubbish such as branches, leaves or plastic bags are blocked on the rubbish baffle.

As shown in Fig. 9, the flow limiting plate 3 is hingedly installed on the short side of the supporting frame provided with the partition, the current limiting plate is a rectangular metal plate, and the current limiting plate is placed under the partition. Several springs are fixed on the upper surface of the free end of the restrictor plate, and the other end of each spring is fixed in the corresponding spring installation hole. In a natural state, the free end of the flow limiting plate is affected by spring tension, the upper surface of the flow limiting plate is attached to the bottom of the support frame, and there is a certain extrusion force between the free end of the flow limiting plate and the bottom of the support frame. As shown in Figure 11, the upper surface of the flow limiting plate is provided with some diversion grooves 31 arranged in parallel, the upper surface of the flow limiting plate is also provided with some confluence grooves 32, the confluence grooves are arranged perpendicular to the flow diversion grooves, and the confluence The length direction of the slot is perpendicular to the plane of rotation of the restrictor plate. The rainwater falling through the leakage hole on the garbage baffle falls on the flow limiting plate, part of the rainwater directly flows down through the diversion groove, and part of the rainwater is collected in the diversion groove through the confluence groove, and then flows down through the diversion groove. For preventing that the rubbish that falls through leak hole slides down through flow limiting plate, be provided with stop bar 33 on the flow limiting plate upper surface, stop bar is perpendicular to the rotation plane of flow limiting plate. Rainwater can flow down through the space between the retaining bar and the diversion groove, while the garbage is blocked by the retaining bar. The diversion trough and the confluence trough can be arranged vertically or intersect. The function of the confluence trough is to collect rainwater into the diversion trough.

As shown in Figure 7 and Figure 8, when the amount of rainwater is less, the rainwater flows on the drainage manhole cover through the ground, and first flows on the garbage baffle, and then directly falls on the flow limiting plate through the leakage hole. , under the pressure of the restrictor plate itself and a small amount of rainwater, the restrictor plate is still in a horizontal state, or the free end of the restrictor plate is slightly inclined downward, and the rainwater flows down through the gap between the restrictor plate and the support frame. As shown in Figure 9, when the amount of rainwater is large and the rainwater covers the drainage manhole cover, under the action of the rainwater and the gravity of the restrictor plate itself, the spring force is overcome, and the free end of the restrictor plate swings downward, so that the restrictor plate In the inclined state, the rainwater leaks on the restrictor plate through the leakage hole at this time, and then flows down through the restrictor plate.

After a period of time, the free end of the garbage baffle can be hooked up to clean up the garbage accumulated on the flow limiting plate to ensure the normal operation of the flow limiting plate.
