Description

Technical Field

[0001] This utility model relates to the field of manhole cover technology, specifically a sewer manhole cover. Background Technology

[0002] The existing manhole covers on sewers are equipped with two drainage holes. These holes can be used to pull the manhole cover off the sewer using a tool with a hook, or to allow water from the road to flow into the sewer. However, because sewers generally have a foul odor, the drainage holes are made relatively small, resulting in slow water flow. In heavy rain, this can easily cause prolonged water accumulation on the road, affecting the passage of vehicles and pedestrians, and failing to meet the needs of use. Utility Model Content

[0003] The purpose of this utility model is to provide a sewer manhole cover that aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the sewer manhole cover includes: Base; A support portion is provided on a base and is rotatably connected to the base. The support portion can be used for water flow and can perform preliminary filtration of the water flow. A flow guide is provided inside the base and below the support. The flow guide is used to guide the water flow passing through the support into the sewer, and at the same time, it can reduce the intensity of the odor in the sewer being emitted upward through the flow guide. Fasteners are used to connect the support portion to the guide portion.

[0005] Preferably, the base includes a ring plate and a square plate disposed on the outer side of the ring plate. A reinforcing plate is disposed between the square plate and the ring plate. A waist hole is provided on the square plate. The bottom of the ring plate extends inward to form an annular bottom ring. A mounting groove is provided on the square plate. A fixing rod is disposed inside the mounting groove.

[0006] Preferably, the support includes a cover, the upper surface of which is provided with a plurality of arc-shaped grooves, all of which have the same center, and wire mesh is provided inside the arc-shaped grooves. An extension plate is provided at one end of the cover, and the extension plate is rotatably connected to the fixing rod.

[0007] Preferably, the flow guide includes a cross-shaped rod with a vertical rod and a handle. The cross-shaped rod has an outer plate and several inner plates, both of which are annular. The outer surface of the outer plate has external threads, and the inner side of the annular plate has internal threads. Two annular mounting plates are respectively provided between adjacent outer and inner plates and between two adjacent inner plates. At least two annular and inclined flow guides are respectively provided on opposite sides of the two mounting plates, and the flow guides on the two mounting plates are staggered.

[0008] Preferably, the fastener is an internal hex bolt, the cover has a placement groove in the middle, and the upright has a threaded hole.

[0009] The beneficial effects of this utility model are: compared with traditional manhole covers, this type of manhole cover assembly has a stronger drainage capacity, which can effectively reduce the water accumulation on the road surface. In addition, while ensuring a large drainage capacity, it can also reduce the overflow of odors from the sewer through the guide plate, resulting in good performance. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-5 As shown, a sewer manhole cover includes: Base; A support portion is provided on a base and is rotatably connected to the base. The support portion can be used for water flow and can perform preliminary filtration of the water flow. A flow guide is provided inside the base and below the support. The flow guide is used to guide the water flow passing through the support into the sewer, and at the same time, it can reduce the intensity of the odor in the sewer being emitted upward through the flow guide. Fasteners are used to connect the support portion to the guide portion.

[0018] Furthermore, the base includes a ring plate 1 and a square plate 2 disposed on the outside of the ring plate 1. A reinforcing plate 3 is disposed between the square plate 2 and the ring plate 1. A waist hole 4 is disposed on the square plate 2. The bottom of the ring plate 1 extends inward to form an annular bottom ring 5. An installation groove 6 is disposed on the square plate 2. A fixing rod 7 is disposed inside the installation groove 6.

[0019] Both ring plate 1 and square plate 2 are made of ductile iron. After aligning ring plate 1 with the manhole of the sewer, square plate 2 is fixed to the ground with bolts.

[0020] Furthermore, the support includes a cover 8, the upper surface of which is provided with a plurality of arc-shaped grooves, all of which have the same center. The interior of the arc-shaped grooves is provided with wire mesh 9, and one end of the cover 8 is provided with an extension plate 10, which is rotatably connected to the fixing rod 7.

[0021] The cover 8 is made of ductile iron. The cover 8 is mainly used to support pedestrians and vehicles. The cover 8 is located above the ring plate 1. The outer diameter of the cover 8 is not less than the outer diameter of the ring plate 1. The ring plate 1 can support the cover 8.

[0022] Rainwater and sewage can flow into the sewer through the arc-shaped groove on the cover 8. The wire mesh 9 can intercept larger-diameter stones, branches and other debris to prevent a large amount of debris from falling into the sewer and reduce the probability of sewer blockage.

[0023] When it is necessary to enter the sewer for sludge removal, the upper end of the sewer can be opened by flipping the cover 8, making it convenient for workers to enter the sewer.

[0024] Furthermore, the flow guide includes a cross-shaped rod 11, on which a vertical rod 12 is provided, and on which a handle 13 is provided. The cross-shaped rod 11 is provided with an outer plate 14 and several inner plates 15. Both the outer plate 14 and the inner plates 15 are annular. The outer surface of the outer plate 14 is provided with external threads, and the inner side of the ring plate 1 is provided with internal threads. Two annular mounting plates 16 are respectively provided between adjacent outer plates 14 and inner plates 15 and between two adjacent inner plates 15. At least two annular and inclined flow guide plates 17 are respectively provided on opposite sides of the two mounting plates 16, and the flow guide plates 17 on the two mounting plates 16 are staggered.

[0025] The guide section can be installed into the ring plate 1 by means of threaded connection, and the bottom ring 5 can support the guide section.

[0026] The cross-shaped rod 11, outer plate 14, and inner plate 15 are made of ductile iron, while the mounting plate 16 and guide plate 17 are made of stainless steel, plastic, or rubber. When the cover 8 is lost due to water flow and strong winds, the internal cross-shaped rod 11, outer plate 14, and inner plate 15 can still cover the manhole of the sewer, thereby preventing pedestrians from accidentally falling into the sewer due to their inability to judge the road conditions, thus providing higher safety.

[0027] The outer plate 14 can be easily threaded onto the ring plate 1 using the handle 13, the upright 12, and the cross-shaped rod 11.

[0028] With the installation plate 16 and the guide plate 17 in place, when rainwater and sewage flow downward through the arc-shaped channel, the water will enter between the two installation plates 16 and be guided back and forth along the guide plate 17 on the installation plate 16, so that the water can enter the sewer normally. At the same time, the wire mesh can also prevent large stones and other debris from clogging between the two installation plates 16.

[0029] Because of the foul odor in the sewer, the odor will spread to the outside of the sewer. However, due to the installed baffles 17, when the foul gas moves upward, multiple baffles 17 will obstruct the upward movement of the gas, thereby effectively reducing the spread of the foul odor at the sewer opening. While ensuring that the water can quickly pass through the cover 8 and the baffles 17 into the sewer, it can also reduce the spread of the odor in the sewer to the outside of the sewer opening, and the effect is good.

[0030] Furthermore, the fastener is an internal hex bolt 18, the cover 8 has a placement groove in the middle, and the upright 12 has a threaded hole.

[0031] The cover 8 can be connected to the upright 12 by means of the internal hex bolts 18, and the outer plate 14 is threaded to the ring plate 1, thus improving the stability of the cover 8 against heavy water and strong winds.

[0032] After removing the hex bolts 18, the cover 8 can be flipped by using the wire mesh 9 on the cover 8 and a tool with hooks. Alternatively, the cover 8 can be flipped by passing a rope through the wire mesh 9.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
