[0002] Drainage systems are crucial infrastructure for modern cities. How to economically and technically optimize the design and renovation of urban drainage systems is a crucial research topic. Drainage systems often account for a significant investment in municipal construction and environmental governance projects. Designing urban drainage systems while meeting specified technical requirements is a crucial issue in planning and design. Consequently, my country has introduced the Urban Drainage Permit Management Measures to address this issue.

[0003] There are many drainage pipes distributed in urban roads, and manhole covers are generally placed at the drainage outlets. The current manhole covers are all movably placed at the drainage outlets. When encountering flood season, staff are required to remove the manhole covers to achieve efficient drainage operations. However, sometimes because the area to be drained is large and the water accumulates quickly, the staff cannot open the manhole covers quickly and in time, and cannot adjust the drainage operation volume in real time according to the amount of rainfall, thereby reducing the efficiency of urban drainage and bringing certain safety hazards. For this reason, we propose a pipeline drainage device. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 2 The present invention provides a pipeline drainage device, comprising:

[0027] The base assembly 100 includes a base 101, on which a cover plate 102 is placed. The cover plate 102 is provided with linearly distributed water guide holes equidistantly arranged around the circumference. A rotating plate 104 is provided below the cover plate 102 to fit the cover plate 102. The rotating plate 104 has through holes that match the water guide holes and partially overlap their initial positions. A vertically distributed rotating rod 105 is provided at the bottom of the rotating plate 104.

[0028] The driving assembly 200 includes a base frame 202 provided below the base 101. A guide cylinder 201 is fixedly and vertically inserted in the center of the base frame 202. The rotating rod 105 is inserted in the guide cylinder 201 and rotates or moves vertically through the driving mechanism to adjust the drainage space.

[0029] This embodiment is configured such that when the depth of water on the road reaches a certain height, the buoyancy of the water drives the rotating rod 105 to rotate through the driving mechanism, so that the through hole on the rod is connected with the water guide hole on the cover plate 102, thereby realizing the primary drainage operation. As the water level gradually rises, the driving mechanism drives the rotating rod 105 to move upward along the guide cylinder 201, so that the cover plate 102 is separated from the base 101, the space at the drain outlet is opened, the drainage efficiency is improved, the uncertain factors of human participation are avoided, and the use effect is good.

[0030] In one embodiment, see Figure 3 and Figure 4The driving mechanism includes a transverse tooth plate 203 provided on one side of the guide cylinder 201. The surface of the rotating rod 105 extending into the guide cylinder 201 is provided with a vertical tooth groove that engages with the transverse tooth plate 203. The surface of the guide cylinder 201 is provided with an opening section. The transverse tooth plate 203 is slidably provided on the L-shaped support plate 204, and the end of the transverse tooth plate 203 is fixedly connected to the bent rod 205, and the end of the bent rod 205 is movably inserted into one of the tubes of the double-tube piston cylinder 206.

[0031] This embodiment is configured such that when the depth of water on the road reaches a certain height, the driving mechanism drives the cross-tooth plate 203 to engage with the rotating rod 105 for transmission connection, drives the rotating plate 104 to rotate, and connects the through hole on it with the water guide hole on the cover plate 102 to achieve primary drainage operation.

[0032] In one embodiment, see Figure 4 and Figure 5 The tail end of the double-tube piston cylinder 206 is connected to the mounting cylinder 207 installed on the base frame 202. The mounting cylinder 207 is connected to the pressurizing box 208 through a conduit, and a movable block 218 is movably provided in the inner cavity of the mounting cylinder 207. The movable block 218 is provided with two air guide holes arranged upper and lower and adapted to the inlet end of the double-tube piston cylinder 206. A floating rod 209 is fixedly inserted on the movable block 218. The floating rod 209 movably passes through the base 101 and extends to its upper surface, and a floating plate 210 is fixedly connected to the top of the floating rod 209. The floating plate 210 is flush with the surface of the cover plate 102 in the initial state.

[0033] This embodiment is configured such that when the depth of water on the road surface reaches a certain height, the floating rod 209 is driven to drive the movable block 218 to move upward, connecting a passage of the double-tube piston cylinder 206, driving the curved rod 205 to move, driving the cross-tooth plate 203 to engage with the rotating rod 105 for transmission connection, driving the rotating plate 104 to rotate, so that the through hole on it is connected with the water guide hole on the cover plate 102, thereby realizing primary drainage operation.

[0034] It should be noted that as the floating rod 209 rises, the gases for driving the rotating rod 105 to rotate and for driving the rotating rod 105 to move upward are introduced in sequence, which is shown in the figure as corresponding passages in the mounting cylinder 207 .

[0035] In one embodiment, see Figure 4 and Figure 5A linkage bent rod 211 is movably inserted in the other tube of the double-tube piston cylinder 206, and the end of the linkage bent rod 211 is fixedly connected to the telescopic push rod 212, and the end of the telescopic push rod 212 is fixedly connected to a pushing member 213. A through hole with the same inner diameter as the guide cylinder 201 is opened on the pushing member 213, and an L-shaped guide plate 215 is fixedly provided on the surface of the guide cylinder 201. One end of the L-shaped guide plate 215 penetrates into the inner cavity of the guide cylinder 201 and its shape is adapted to the shape of the inner cavity of the guide cylinder 201. The L-shaped guide plate 215 is movably provided with a blocking block 214, and a limit spring 216 connected to it is provided on one side of the blocking block 214, and the blocking block 214 and the pushing member 213 are located on the same horizontal plane.

[0036] This embodiment is configured such that when the depth of water on the road surface continues to rise, as the water level gradually rises, another passage connected to the double-tube piston cylinder 206 drives the pusher 213 to move, pushing the blocking block 214 along the L-shaped guide plate 215 in the guide cylinder 201, releasing the restriction on the push rod 219, and its top end quickly and tightly contacts the bottom surface of the rotating rod 105, and pushes the overall structure of the rotating plate 104 and the cover plate 102 upward, so that it separates from the base 101, opens the space at the drain outlet, and improves the drainage efficiency.

[0037] In one embodiment, see Figure 4 and Figure 5 The inner cavity of the guide cylinder 201 is provided with a push rod 219, which is a telescopic structure. The top of the push rod 219 is initially in contact with the bottom surface of the blocking block 214. The inner cavity of the push rod 219 is pressurized, and the surface of the push rod 219 is provided with an air filling pipe 217. The push rod 219 is a telescopic structure, and the top of the push rod 219 is initially in contact with the bottom surface of the blocking block 214.

[0038] This embodiment is configured such that when the water on the road surface reaches a certain height, the curved rod 205 can drive the gas in the double-tube piston cylinder 206 to flow, thereby moving the pusher 213, pushing the blocking block 214 in the guide cylinder 201 along the L-shaped guide plate 215, releasing the restriction on the push rod 219, and its top end quickly and tightly contacts the bottom surface of the rotating rod 105, and pushes the overall structure of the rotating plate 104 and the cover plate 102 upward, so that it separates from the base 101, opens the space at the drain outlet, and improves the drainage efficiency.

[0039] In one embodiment, a water level sensor is provided on the base 101, and a hydraulic rod 220 for auxiliary lifting is provided on one side of the floating rod 209. When the water level detected by the water level sensor reaches a set value, a feedback signal is generated to control the hydraulic rod 220 to assist the floating rod 209 in rising.

[0040] This embodiment is configured such that when the depth of water on the road surface reaches a relatively high level, the hydraulic rod 220 assists the floating rod 209 in moving upward, so that another passage of the double-tube piston cylinder 206 can be connected, and then the push rod 219 can lift the cover plate 102, thereby expanding the drainage channel, improving drainage efficiency, avoiding the problem of the cover plate 102 being difficult to move upward due to insufficient buoyancy of the floating plate 210, and ensuring smooth drainage.

[0041] In one embodiment, see Figure 1 and Figure 2 The bottom surface of the cover plate 102 is provided with a mesh panel 103, which is detachably connected to the base 101 and detachably connected to the cover plate 102. In this embodiment, the mesh panel 103 is provided to prevent debris from entering the drainage pipe and avoid clogging.

[0042] In one embodiment, see Figure 6 A trash net 300 is provided at the bottom of the mesh enclosure 103, and an annular groove 301 for accommodating the trash net 300 is opened on the base 101. The trash net 300 is folded and stored in the annular groove 301. Hooks 302 are equidistantly provided in the annular groove 301, and one end of the trash net 300 is connected to the hook 302 through a hook 303.

[0043] This embodiment is configured such that when the depth of water on the road reaches a high level, the cover plate 102 is lifted up and the trash net 300 is pulled out simultaneously to intercept trash in the open space around the cover plate 102, thereby avoiding the problem of debris clogging the drainage channel and ensuring smooth drainage after the drainage channel is expanded.

[0044] In one embodiment, a reflective layer is sprayed on the surface of the cover plate 102 and the floating plate 210. This embodiment is arranged in this way to easily remind passers-by around and improve safety.

[0045] When the depth of water on the road reaches a certain height, the floating rod 209 is driven to drive the movable block 218 to move upward, connecting a passage of the double-tube piston cylinder 206, driving the curved rod 205 to move, driving the cross-tooth plate 203 to engage with the rotating rod 105 for transmission connection, driving the rotating plate 104 to rotate, so that the through hole on it is connected with the water guide hole on the cover plate 102, realizing the primary drainage operation.

[0046] When the depth of water on the road continues to rise, as the water level gradually rises, another passage connected to the double-tube piston cylinder 206 drives the pusher 213 to move, pushing the blocking block 214 in the guide cylinder 201 along the L-shaped guide plate 215, releasing the restriction on the push rod 219, and its top end quickly and tightly contacts the bottom surface of the rotating rod 105, and pushes the overall structure of the rotating plate 104 and the cover plate 102 upward, so that it separates from the base 101, opens the space at the drain outlet, and improves the drainage efficiency.
