Description

Technical Field

[0001] The utility model relates to the field of manhole covers, in particular to a manhole cover with an anti-blocking function. Background Art

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

[0003] Existing manhole covers generally have a filter installed at the bottom of the well to prevent garbage from clogging the well. Over time, more and more garbage is intercepted on the filter, which may cause the risk of the filter being blocked. Staff are required to observe the well regularly to prevent it from being blocked.

[0004] Therefore we need to develop a manhole cover with anti-clogging function. Utility Model Content

[0005] In order to overcome the disadvantage that a filter screen is generally installed at the bottom of the well in the existing manhole cover, which may cause water to be blocked when the filter screen is full, the utility model provides a manhole cover with an anti-blocking function.

[0006] The technical solution of the utility model is: a manhole cover with an anti-clogging function, including a manhole cover seat, a cover plate, a filter screen, an electric push rod, a scraper and a guide rod, a cover plate is placed on the upper part of the manhole cover seat, a plurality of water inlets are opened on the cover plate, a filter screen is installed in the manhole cover seat, an electric push rod is installed on the rear side of the filter screen, a scraper is connected to the electric push rod, guide rods are installed on the left and right sides of the manhole cover seat, and the two guide rods pass through the scraper.

[0007] Furthermore, it also includes a collecting frame, a pull rod and an elastic member. The front side of the filter is slidably connected to the collecting frame, and pull rods are provided on both sides of the collecting frame for sliding. Elastic members are sleeved on both sides of the pull rod, and both ends of the elastic member are respectively connected to the collecting frame and the pull rod.

[0008] Furthermore, it also includes a rotating block, a rotating plate and a torsion spring. The cover plate is rotatably provided with a rotating block, the rotating block passes through the cover plate, a rotating plate is installed at the lower part of the rotating block, and the rotating plate is provided with openings corresponding to the number of the cover plate. The rotating block is sleeved with a torsion spring, and the two ends of the torsion spring are respectively connected to the cover plate and the rotating block.

[0009] Furthermore, it also includes handles, and handles are installed on the left and right sides of the collection frame.

[0010] Furthermore, it also includes a latch, which is slidably provided on the rotating block and can be clamped on the cover plate.

[0011] Furthermore, a plurality of anti-slip grooves are provided on the circumference of the upper portion of the rotating block.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model starts the electric push rod, which pushes the scraper forward along the guide rod. The forward movement of the scraper pushes the garbage on the filter screen onto the collection frame, so that the filter screen is cleaned and the sewer water flow is smooth.

[0013] 2. The utility model pulls out the latch and then rotates the rotating block. The rotation of the rotating block will drive the rotating plate to rotate together. At the same time, the rotation of the rotating block will also stretch the torsion spring. When the rotating plate is rotated to align with the opening on the cover plate, the latch can be inserted back into the rotating block and the cover plate, and the rotating plate can be fixed. In this way, a large amount of water can be discharged, achieving the effect of smoothly discharging water even when there is a lot of water flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The preferred technical solution of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0021] Example 1

[0022] A manhole cover with anti-clogging function, such as Figure 1-Figure 5As shown, it includes a manhole cover seat 1, a cover plate 2, a filter screen 3, an electric push rod 4, a scraper 5, a guide rod 6, a collection frame 7, a pull rod 8, an elastic member 9 and a handle 10. A cover plate 2 is placed on the upper part of the manhole cover seat 1, and a plurality of water inlets are opened on the cover plate 2, and the number of the water inlets is six. A filter screen 3 for intercepting garbage is installed in the manhole cover seat 1, and an electric push rod 4 is installed on the rear side of the filter screen 3. A scraper 5 is connected to the electric push rod 4, and the scraper 5 can scrape the garbage on the filter screen 3. Guide rods 6 are installed on the left and right sides of the manhole cover seat 1, and the two guide rods 6 both penetrate the scraper 5. The front side of the filter screen 3 is slidably connected to the collection frame 7. Pull rods 8 are provided on the left and right sides of the collection frame 7 when sliding, and the pull rod 8 can clamp the collection frame 7. Elastic members 9 are sleeved on the front and rear sides of the pull rod 8, and the two ends of the elastic member 9 are respectively connected to the collection frame 7 and the pull rod 8. Handles 10 for convenient pulling by the staff are installed on the left and right sides of the collection frame 7.

[0023] When the filter 3 on the manhole cover seat 1 intercepts a lot of garbage, the electric push rod 4 is first started, and the electric push rod 4 will push the scraper 5 forward along the guide rod 6. The forward movement of the scraper 5 will push the garbage on the filter 3 to the collecting frame 7, so that the filter 3 is cleaned. When the collecting frame 7 is also full of garbage, the staff will pull the two pull rods 8 inward to stretch the elastic member 9. When the pull rods 8 are pulled to disengage from the filter 3, the staff will pull the handle 10 to pull the collecting frame 7 out of the filter 3 and pour out the garbage on the collecting frame 7.

[0024] Example 2

[0025] On the basis of Example 1, Figure 1 , Figure 4 and Figure 5 As shown, it also includes a rotating block 11, a rotating plate 12, a torsion spring 13 and a latch 14. The rotating block 11 is rotatably provided on the cover plate 2. A plurality of anti-skid grooves are circumferentially provided on the upper part of the rotating block 11. The number of anti-skid grooves is eight. The rotating block 11 passes through the cover plate 2. A rotating plate 12 is fixedly installed on the lower part of the rotating block 11. The rotating plate 12 is provided with openings corresponding to the number of the cover plate 2. A torsion spring 13 is sleeved on the rotating block 11. The two ends of the torsion spring 13 are respectively connected to the cover plate 2 and the rotating block 11. A latch 14 is slidably provided on the rotating block 11. The latch 14 can fix the rotating block 11 and the rotating plate 12, and the latch 14 can be stuck on the cover plate 2.

[0026] When it rains heavily, the staff can pull out the latch 14 and then rotate the rotating block 11. The rotation of the rotating block 11 will drive the rotating plate 12 to rotate together. At the same time, the rotation of the rotating block 11 will also stretch the torsion spring 13. When the rotating plate 12 is rotated to align with the opening on the cover plate 2, the latch 14 can be inserted back into the rotating block 11 and the cover plate 2, and the rotating plate 12 can be fixed, so that a large amount of water can be discharged.
