Description

Technical Field

[0001] This invention belongs to the field of municipal engineering infrastructure protection technology, specifically relating to a fully automatic circular storm and sewage well cleaning device for municipal engineering. Background Technology

[0002] Municipal sewer systems are an indispensable part of modern urban infrastructure, primarily used for collecting and discharging sewage and wastewater, draining urban surface runoff, and preventing urban flooding. They ensure the normal operation of the city and play a vital role in environmental protection, public health, urban planning, and water resource management, serving as a crucial component of "sponge city" construction. Municipal sewer systems typically have drainage outlets every 25-50 meters for discharging sewage and rainwater. These outlets are covered with manhole covers to prevent people or objects from falling in. Circular manhole covers are generally 600mm, 700mm, or 800mm in diameter and typically have circular, rectangular, or grid-shaped drainage holes. However, these holes easily allow mud, leaves, weeds, and road debris to accumulate, clogging the sewers and rendering the sewers ineffective. Cleaning sewers usually relies on manual labor, which is time-consuming, physically demanding, and conducted in harsh environments. During flood season, the inability to complete cleaning and retrieval quickly and efficiently can easily lead to urban flooding. Against this backdrop, it is essential to develop a fully automatic rainwater and sewage well cleaning device. Summary of the Invention

The linked rotating blade assembly includes one active blade, several first passive blades, several second passive blades, and one third passive blade. The number of first passive blades equals the number of second passive blades, or the number of first passive blades equals the number of second passive blades plus one. The active blade, first passive blades, second passive blades, and third passive blade are all rectangular in shape, adapted to the circular bottom surface of the barrel. Each of the active blade, first passive blade, second passive blade, and third passive blade has a mounting hole at its geometric center that matches the main drive shaft. The active blade, first passive blade, second passive blade, and third passive blade are connected to the main drive shaft through their respective mounting holes. The first passive blade is located at the bottom layer of the linked rotating blade assembly, and the third passive blade is located at the top layer. The first and second passive blades are alternately installed between the active blade and the third passive blade from bottom to top. A pair of second limiting plates are obliquely positioned at the left rear end and right front end of the active blade, and a pair of first linkage protrusions are obliquely positioned at the left front edge and right rear edge of the active blade.

The moving protrusion, and the position and size of the second arc-shaped groove are adapted to the second linkage protrusion; the left front edge and right rear edge of the third passive blade are diagonally provided with a pair of third arc-shaped grooves, and the position and size of the third arc-shaped groove are adapted to the third linkage protrusion on the adjacent second passive blade or to the second linkage protrusion on the adjacent first passive blade (when the number of first passive blades = the number of second passive blades, when the first passive blades and second passive blades are alternately arranged between the active blades and the third passive blades from bottom to top, the second passive blade is adjacent to the topmost third passive blade; conversely, when the number of first passive blades = the number of second passive blades + 1, the first passive blade... When the blade and the second passive blade are alternately arranged between the active blade and the third passive blade from bottom to top, the first passive blade is adjacent to the topmost third passive blade. A third limiting plate is provided on the right rear edge of the third passive blade. The first linkage protrusion is embedded in the first arc-shaped groove to connect the active blade and the first passive blade. The second linkage protrusion is embedded in the second arc-shaped groove to connect the first passive blade and the second passive blade. The third linkage protrusion on the second passive blade adjacent to the third passive blade or the second linkage protrusion on the first passive blade adjacent to it is embedded in the third arc-shaped groove to connect the third passive blade with the second passive blade or the first passive blade adjacent to it.

[0011] Preferably, a circular retaining ring is provided on the inner wall of the bottom end of the barrel located below the active blade. This is because the main drive shaft and the active blade are connected together and can rotate together. When the upper part of the main drive shaft is connected to the second reducer, there is a possibility of vertical movement. When it moves downward, the active blade may fall off. Therefore, a circular retaining ring is provided to block the active blade and prevent it from falling off.

[0012] Ideally, the number of the first passive blades equals the number of the second passive blades.

[0013] Ideally, the active blade, the first passive blade, the second passive blade, and the third passive blade have the same width, which makes it easy for all blades to be completely combined together.

[0021] Working process: The bottom of the barrel 5 of the above-mentioned device is initially in the open state, that is, all blades are closed together. When preparing to clean, the device is lowered into the storm drain by hooking the handle ring 9 with the hoisting rope, but ensuring that the top of the barrel 5 is not lower than the top of the storm drain. The drive motor 1 provides power, which is reduced by the first reducer 2 and the second reducer 3 and then transmitted to the main drive shaft 6. The main drive shaft 6 is connected to the active blade 10. The active blade 10 is provided with a first linkage protrusion 131. The first linkage protrusion 131 is embedded in the first arc-shaped groove 141 of the first passive blade 111. When the active blade 10 rotates clockwise, the first linkage protrusion 131 can be driven by the first arc-shaped groove 141 of the first passive blade 111. The first passive blade 111 rotates and simultaneously achieves a limiting position. A second linkage protrusion 132 is also provided on the first passive blade 111. Linkage is achieved through a second arc-shaped groove 142 provided on the second passive blade 112. The first passive blade 111 and the second passive blade 112 are alternately arranged to achieve linkage between them. The top blade is the third passive blade 113. Since the third passive blade 113 only acts as a driven component and does not transmit power upwards, it is provided with a third arc-shaped groove 143 to receive the power transmitted from the second passive blade 112. Furthermore, a third limiting plate 123 is provided on the third passive blade 113 to prevent the third passive blade from... If rotation beyond the set position fails to seal the bottom of the device, a second limiting plate 122 is provided on the active blade 10. When the active blade 10 rotates to its position, the second limiting plate 122 on the active blade 10 contacts the lower mounting plate 7, and the active blade 10 stops working. At this time, all blades of the device are fully extended, and the bottom of the device barrel 5 is sealed. The first reducer 2 and the second reducer 3 can only transmit power in one direction, and there will be no blade slippage or automatic opening. The structure is stable. During the process of the bottom of the barrel 5 gradually closing, dirt enters the barrel 5 without restriction. When the bottom of the barrel 5 is sealed, the device is lifted upwards, and the opening operation is performed as follows to open the barrel. At the bottom of body 5, the waste is poured out. The opening operation is as follows: the drive motor 1 rotates in the opposite direction. After being reduced by the first reducer 2 and the second reducer 3, the power is transmitted to the main drive shaft 6. The main drive shaft 6 rotates in the opposite direction, driving the active blade 10 to rotate in the opposite direction, i.e., counterclockwise. The active blade 10 is provided with a second limiting plate 122. When the second limiting plate 122 contacts the first passive blade 111, it drives the first passive blade 111 to rotate. When it rotates to the position of the second passive blade 112, it drives the second passive blade 112 to rotate, and so on, driving all blades to rotate until all blades contact the limiting structure of the lower fixed plate 8. All blades merge together, and at this time the bottom of the device is in the open state.
