Description

Technical Field

[0001] The utility model belongs to the technical field of manhole covers, and particularly relates to a safe manhole cover for a new type of municipal road. Background Art

[0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Generally, they are circular and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] The existing manhole covers on the market have the following problems when applied:

[0004] 1. When installing traditional manhole covers, they are generally directly installed on the surface of the wellbore without fixing devices. Due to the complex surface conditions of the road, when vehicles and pedestrians pass by the manhole cover, the manhole cover is likely to become loose, making it unsafe to use.

[0005] 2. When using traditional manhole covers, when the road encounters heavy rain, after long-term use, the water leakage holes on the surface of the manhole cover are easily blocked by impurities, and the water leakage holes are small, making it difficult to find a suitable tool for cleaning, and the cleaning is not convenient. Content of the Utility Model

[0028] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a safety manhole cover for a new type of municipal road of the present utility model with reference to the accompanying drawings.

[0029] As Figures 1-5 shown, a safety manhole cover for a new type of municipal road of the present utility model includes a manhole cover body 1. An arc-shaped plate 7 is provided at the bottom of the manhole cover body 1. The arc-shaped plates 7 are symmetrically distributed. A second square plate 6 is fixedly connected to the surface of the arc-shaped plate 7. A spring 5 is fixedly connected to the surface of the second square plate 6. One end of the spring 5 is fixedly connected to a first square plate 3. A pressing plate 4 is provided on the side of the first square plate 3. An installation plate 15 is fixedly connected to the side of the arc-shaped plate 7. By adding an arc-shaped plate 7 at the bottom of the manhole cover body 1, a second square plate 6 is installed on the surface of the arc-shaped plate 7, a spring 5 is installed on the surface of the second square plate 6, a first square plate 3 is installed at one end of the spring 5, a pressing plate 4 is added to the side of the first square plate 3, and an installation plate 15 is added to the side of the arc-shaped plate 7. When the manhole cover needs to be installed, only need to first install the arc-shaped plate 7 on the bottom of the manhole cover body 1 through the installation plate 15, and then directly install the manhole cover body 1 on the surface of the manhole opening. At this time, the arc-shaped plate 7 presses against the side wall of the sewer through the spring 5 connecting the pressing plate 4. By squeezing, the spring 5 contracts. At this time, the pressing plate 4 makes the installation of the manhole cover body 1 more stable and not prone to looseness, and it is safer to use.

[0030] A water leakage port 10 is opened on the surface of the manhole cover body 1. A frame body 2 is embedded in the water leakage port 10. A connecting rod body 8 is fixedly connected to the bottom of the frame body 2. A baffle 17 is fixedly connected to the side of the frame body 2. A fixing rod 16 is fixedly connected to the bottom of the baffle 17. The fixing rod 16 is inserted into the surface of the manhole cover body 1. By opening a water leakage port 10 on the surface of the manhole cover body 1, embedding a frame body 2 in the water leakage port 10, installing a rod body 8 at the bottom of the frame body 2, installing a baffle 17 on the side of the frame body 2, and installing a fixing rod 16 at the bottom of the baffle 17. When the water leakage port 10 of the manhole cover body 1 is blocked and needs to be cleaned, only need to directly pull out the blocked frame body 2 at this time, clean the frame body 2. After cleaning, install the frame body 2 back into the water leakage port 10, and insert the fixing rod 16 into the manhole cover body 1 to fix the frame body 2. At this time, it can make the cleaning of the water leakage port 10 more convenient.

[0031] The surface of the manhole cover body 1 is fixedly connected with a threaded rod 12. The threaded rod 12 is inserted inside the mounting plate 15. By installing the threaded rod 12 on the surface of the manhole cover body 1 and inserting the mounting plate 15 outside the threaded rod 12 for fixation, it is convenient to fix the arc-shaped plate 7.

[0032] An internal thread ring 14 is sleeved outside the threaded rod 12. The side of the internal thread ring 14 is fixedly connected with a rotating rod 13. After the threaded rod 12 is installed, the internal thread ring 14 is sleeved outside the threaded rod 12, and the rotating rod 13 is held to tighten the internal thread ring 14. At this time, the arc-shaped plate 7 can be fixed.

[0033] The bottom of the fixing rod 16 is fixedly connected with a ball head 9. The number of ball heads 9 is four. By installing the ball head 9 at the bottom of the fixing plate and inserting the ball head 9 into the surface of the manhole cover body 1, the fixing rod 16 can be prevented from coming out of the manhole cover body.

[0034] A pull plate 11 is provided on the side of the baffle 17. The pull plate 11 and the baffle 17 are connected by a rotating shaft. By installing the pull plate 11 on the side of the baffle 17, when the water leakage port 10 needs to be cleaned, only the pull plate 11 needs to be pulled up through the rotating shaft, and the frame body 2 can be conveniently pulled up through the pull plate 11.

[0035] The working principle of the new type of safety manhole cover for municipal roads: When applying this manhole cover, first install the arc-shaped plate 7 at the bottom of the manhole cover body 1 through the mounting plate 15, insert the mounting plate 15 outside the threaded rod 12, and hold the rotating rod 13 to tighten the internal thread ring 14. At this time, the arc-shaped plate 7 can be fixed. Then directly install the manhole cover body 1 on the surface of the well opening. At this time, the arc-shaped plate 7 is connected by a spring 5 to squeeze the plate 4 and squeeze against the side wall of the sewer. Through the contraction of the extrusion spring 5, the squeezing plate 4 makes the installation of the manhole cover body 1 more stable and not prone to loosening. When the water leakage port 10 of the manhole cover body 1 is blocked and needs to be cleaned, only the pull plate 11 needs to be pulled up through the rotating shaft, and the frame body 2 can be directly pulled up through the pull plate 11 to clean the frame body 2. After cleaning, install the frame body 2 back into the water leakage port 10, and insert the fixing rod 16 and the ball head 9 into the manhole cover body 1 to fix the frame body 2.
