Description

Technical Field

[0001] This invention relates to a surface cleaning device for manhole covers used on municipal roads, specifically a surface cleaning device for manhole covers used on municipal roads. Background Technology

[0002] In modern cities, many roads are prone to flooding during heavy rain. During the rainy season, road drainage systems are essential to ensure road safety. However, rainwater carries large amounts of branches and leaves, and rapid rainfall can cause these debris to clog manhole covers, leading to significant flooding and making roads impassable. Most existing manhole covers are typically made of ductile iron.

[0003] Therefore, when roads are flooded and impassable, cleaning personnel will manually remove branches, leaves, and other debris from the surface of the manhole covers. They will use tools such as pliers and hooks to clear the blockage and unclog the manholes. However, this process is difficult and time-consuming. In the rainy season, when there is a lot of water on the road, it is difficult for cleaning personnel to get a foothold, which can easily lead to slips and falls. In addition, some of the debris is large and heavy, making it even more difficult to clean and unclog the manholes. Summary of the Invention

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1-2As shown, a manhole cover surface cleaning device for municipal roads includes an annular fixing seat 1. The annular fixing seat 1 has a fixing cavity 11 in the middle. Multiple horizontally rotatable cutting blades 12 are installed inside the fixing cavity 11. The cutting blades 12 are existing technology and will not be described in detail here. The various cutting blades 12 are combined to form a cutting blade group, which can cut and crush debris such as branches and leaves entering the fixing cavity 11 through horizontal rotation, reducing the volume of the debris for rapid transport with accumulated water, avoiding blockage of external debris transport pipes, and improving cleaning efficiency. Below the fixing cavity 11 is a cleaning seat 2 connected to the bottom of the annular fixing seat 1. The cleaning seat 2 is located below the fixing cavity 11 and connected to the bottom of the annular fixing seat 1. Multiple... A number of evenly distributed cleaning holes 21, connected to the fixed cavity 11, are provided to allow accumulated debris such as branches and leaves on the manhole cover surface to pass through and enter the fixed cavity 11. The multiple cleaning holes 21 improve cleaning efficiency and divert the debris, preventing excessive debris from entering the fixed cavity 11 at once, which could lead to the cutting blades 12 being unable to completely break up the debris, affecting cleaning efficiency, or causing blockage within the fixed cavity 11. This reduces the burden on the cutting blades 12 in breaking up the debris. The inner wall of each cleaning hole 21 has multiple air holes 211 for delivering high-pressure airflow into the fixed cavity 11. The air holes 211 deliver high-pressure airflow into the fixed cavity 11, allowing the cleaning holes to... A negative pressure environment is created inside the vent 211, which allows for rapid and efficient suction and transport of accumulated garbage on the surface of the manhole cover, enhancing the cleaning intensity. Simultaneously, the high-pressure airflow within the vent 211 flows upwards, preventing the mixture of transported garbage and water from clogging the vent 211, thus ensuring its unobstructed flow during garbage removal. The top of the annular fixing seat 1 is equipped with multiple conveying holes 13 communicating with the fixing cavity 11. These conveying holes 13 allow for rapid transport of crushed garbage and water within the fixing cavity 11. The multiple conveying holes 13 also allow for diverting the transport of crushed garbage and water, reducing the transport pressure on the conveying holes 13 and the conveying cover 14, and minimizing impact on these components. To enhance impact resistance and extend the service life of components, the top surface of the annular fixed base 1 is provided with a conveying cover 14 that surrounds each conveying hole 13. The conveying cover 14 surrounds each conveying hole 13, forming a protective enclosure, allowing the crushed garbage and water in the fixed cavity 11 to enter the conveying cover 14 through each conveying hole 13 for rapid transport. The top of the conveying cover 14 is provided with a connecting section 141 that communicates with each conveying hole 13 and can be connected to an external garbage conveying pipe. The connecting section 141 can be connected to an external garbage conveying pipe, allowing the garbage and water entering the conveying cover 14 to be transported to the outside through the connecting section 141, achieving the effect of cleaning and transporting, and preventing garbage and water from clogging the manhole cover again.

[0019] During the rainy season, manhole covers in cities are prone to clogging, leading to significant water accumulation and making roads impassable. Cleaning personnel can place a device on top of the manhole cover, with the cleaning seat positioned directly above it. When high-pressure airflow enters the fixed chamber 11 through the air hole 211, a negative pressure environment is created within the cleaning hole 21. This suctions out accumulated debris such as branches and leaves, along with the accumulated water, from the manhole cover. The debris and water are then quickly transported to the fixed chamber 11, where they are rapidly cut and broken up by the cutting blades 12. The broken debris and water are then carried by the flowing water through the conveying hole 13 and along the conveying cover 14 to the external waste conveying pipe. This achieves rapid cleaning of accumulated debris and water from the manhole cover, and can also pump out some of the accumulated water, reducing water accumulation on the road. Furthermore, it requires no manual operation, providing automated cleaning, reducing cleaning difficulty, improving cleaning efficiency, and effectively avoiding danger to cleaning personnel.

[0020] like Figure 3 As shown, the outer wall of the cleaning seat 2 is provided with an annular positioning seat 3 that is connected to the bottom of the annular fixing seat 1. The annular positioning seat 3 is located around the cleaning seat 2 and fixes the cleaning seat 2. The inner wall of the annular positioning seat 3 is provided with multiple vertically arranged slots 31. The outer wall of the cleaning seat 2 is provided with multiple protrusions 22 that cooperate with the slots 31. The cleaning seat 2 forms a snap-fit ​​by the cooperation between the protrusions 22 on its outer wall and the slots 31 of the annular positioning seat 3, thereby achieving circumferential positioning of the cleaning seat 2 and ensuring the structural stability of the cleaning seat 2.

[0021] like Figure 2 and 4As shown, an annular ventilation chamber 23 is provided around the periphery of the conveying hole 13, corresponding to the interior of the cleaning seat 2. The annular ventilation chamber 23 connects to each air hole 211 in the cleaning hole 21, so that the high-pressure airflow is uniformly output from the air hole 211 along the annular ventilation chamber 23. The air hole 211 is obliquely upward and connects to the annular ventilation chamber 23 and the conveying hole 13. The oblique upward orientation of the air hole 211 allows the high-pressure airflow to carry garbage and accumulated water into the fixed cavity 11, and the oblique upward airflow prevents garbage and accumulated water from entering the air hole 211 and causing blockage. The middle of the cleaning seat 2 is provided with an installation cavity 24 that connects to each annular ventilation chamber 23. The installation cavity 24 is connected to each annular ventilation chamber 23 and is equipped with an air pump 25. The air pump 25 is existing technology and will not be described in detail here. The air pipe of the air pump 25 can be installed in each part. The wall thickness of the component is set and extends to the top to communicate with the external environment, so as to facilitate the output of high-pressure airflow. The air pump 25 outputs high-pressure airflow into the mounting cavity 24. The high-pressure airflow is ejected from each air hole 211 along the annular ventilation cavity 23, forming a negative pressure environment inside the cleaning hole 21. The bottom of the mounting cavity 24 is provided with a cover 241. The air pump 25 is located on the end face of the cover 241. The cover 241 is threadedly connected to the bottom inner wall of the mounting cavity 24. The air pump 25 is fixed on the cover 241 to ensure the stability of the air pump 25 position. The cover 241 is threadedly connected to the bottom of the mounting cavity 24 to facilitate the quick installation of the air pump 25. A sealing ring is provided between the outer wall of the cover 241 and the inner wall of the mounting cavity 24. The sealing ring can enhance the sealing between the cover 241 and the mounting cavity 24 to prevent garbage and water from entering the mounting cavity 24.

[0022] like Figure 2 and 4 As shown, a vertically arranged rotating shaft 15 is provided in the middle of the fixed cavity 11 and passes upward through the annular fixed seat 1. The rotating shaft 15 is rotatably disposed in the fixed cavity 11. The upper end of the rotating shaft 15 passes through the top of the annular fixed seat 1, and the lower end of the rotating shaft 15 is rotatably connected to the top surface of the cleaning seat 2. Each cutting blade 12 is evenly arranged on the side wall of the rotating shaft 15. The top of the annular fixed seat 1 is provided with a drive motor 16 connected to the rotating shaft 15. When the drive motor 16 is started, it can drive the rotating shaft 15 to rotate. The rotating shaft 15 can drive each cutting blade 12 to rotate synchronously, cutting and crushing the garbage such as branches and leaves accumulated on the manhole cover in the fixed cavity 11.

[0023] like Figure 4-5As shown, the annular positioning seat 3 has an annular fixing housing 32 with a bottom opening. The annular fixing housing 32 is fixed to the bottom of the annular positioning seat 3. When the annular positioning seat 3 is on the manhole cover, the annular fixing housing 32 is located on the top surface of the edge of the manhole cover. The annular fixing housing 32 contains an electromagnet 321 that can be magnetically connected to the surface of the manhole cover. The electromagnet 321 is existing technology, which uses electrical control to start and stop the magnetic attraction. Most manhole covers on the market are made of ductile iron, which can produce a magnetic attraction effect with magnetic materials. The opening at the bottom of the annular fixing housing 32 exposes the magnetic attraction part of the electromagnet 321. When the annular fixing housing 32 is on the manhole cover, the annular fixing housing 32 is fixed to the bottom of the manhole cover. When the device is positioned on the manhole cover, the electromagnet 321 is activated, allowing it to magnetically connect with the manhole cover. This quickly connects and secures the annular positioning seat 3, cleaning seat 2, and annular fixing seat 1 to the manhole cover, preventing the cleaning seat 2 from loosening during cleaning and ensuring stability. The bottom surface of the cleaning seat 2 is higher than the bottom surface of the electromagnet 321, and a gap is formed between the bottom surface of the cleaning seat 2 and the surface of the manhole cover. This prevents the cleaning seat 2 from pressing tightly against the surface of the manhole cover, which would make it difficult for some garbage to be sucked and transported by the cleaning hole 21. This increases the flow of garbage and water accumulated on the manhole cover, facilitating the rapid and efficient suction and transport of garbage and water accumulated on the manhole cover by the cleaning hole 21.

[0024] like Figure 4-5As shown, the bottom of the annular positioning seat 3 corresponds to the outer side of the annular fixed housing 32 and is provided with an annular support block 33 that can move up and down elastically. The annular support block 33 is adapted to the outer diameter of commonly used manhole covers. During cleaning, the annular support block 33 is located around the manhole cover, and the inner edge of the annular support block 33 can cooperate with the outer edge of the manhole cover. The top of the annular support block 33 is provided with an annular limiting groove 331, and the bottom of the annular positioning seat 3 is provided with an annular limiting block 34 located in the annular limiting groove 331. The annular support block 33 forms a movable connection with the bottom of the annular positioning seat 3 through the connection of the annular limiting groove 331 and the annular limiting block 34. When the electromagnet 321 is magnetically connected to the manhole cover, the annular support block 33 remains in contact with the ground. At the same time, the annular support block 33 moves upward synchronously through the annular limiting block 34 and the annular limiting groove 331 to adapt to the connection between the electromagnet 321 and the manhole cover and the connection between the annular support block 33 and the ground. The contact between the annular support block 33 and the annular limit block 34 is such that the annular support block 33 can adapt to the height of the manhole cover protruding from the ground, ensuring that the electromagnet 321 can be stably magnetically connected to the surface of the manhole cover. The end of the annular limit block 34 is provided with an outward protrusion 341 that abuts against the side wall of the annular limit groove 331, and the opening of the annular limit groove 331 is provided with an inward protrusion 332 that abuts against the side wall of the annular limit block 34. The cooperation of the outward protrusion 341 and the inward protrusion 332 facilitates the sliding limit of the annular limit block 34 and the annular limit groove 331, realizing the movable connection of the annular support block 33 and preventing the annular support block 33 from detaching. The annular limit groove 331 is provided with multiple telescopic springs 333 connected to the annular limit block 34. The setting of the telescopic springs 333 allows the annular support block 33 to automatically reset, facilitating the repeated action of the annular support block 33 and increasing the buffering effect when the device is placed on the ground.

[0025] like Figure 1-2 As shown, an annular support plate 4 is provided on the outer wall of the annular fixed base 1. The annular support plate 4 is fixed to the side wall of the annular fixed base 1. Two symmetrically arranged screws 41 are threaded through the annular support plate 4. The screws 41 are threadedly connected to the annular support plate 4. The two symmetrically arranged screws 41 are threadedly engaged with the annular support plate 4. Multiple drive handles 411 are provided at the upper end of the screws 41, and a support plate 412 is provided at the lower end of the screws 41. After the garbage on the manhole cover is cleaned, there is still water accumulation. The bottom of the cleaning base 2 may adhere to the water accumulation. If the device is difficult to move, the drive handles 411 can be held and the screws 41 can be rotated. This will cause the support plate 412 at the bottom of the screws 41 to gradually contact the ground and the screws 41 to continue rotating. This will cause the annular support plate 4 to move upward relative to the screws 41, thereby raising the annular fixed base 1. This will allow the device to be quickly and effectively separated from the manhole cover, making it easier to move the device with less effort.

[0026] like Figure 4As shown, the conveying hood 14 has multiple conveying channels 142 connected to the conveying holes 13 inside. Each conveying channel 142 inside the conveying hood 14 is connected to each conveying hole 13 to facilitate the diversion and conveying of crushed waste and accumulated water. A diversion rib 131 is formed between every two conveying holes 13. The bottom of the diversion rib 131 is set with an arc-shaped structure. The diversion rib 131 can quickly divert crushed waste and accumulated water. The arc-shaped structure at the bottom of the diversion rib 131 can improve the diversion efficiency and prevent some waste from being blocked at the bottom of the diversion rib 131 and accumulating, making it difficult to clean and convey. This ensures the quality of waste diversion. The inner side of the connecting section 141 is provided with mounting holes 143 that are connected to each conveying channel 142 and can be connected to the external waste conveying channel. The mounting holes are connected to each conveying channel 142 and connected to the external waste conveying channel, so that waste and accumulated water can enter the external waste conveying channel for external transportation and cleaning along the conveying channel 142.

[0027] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
