Description

Pipeline flushing device TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline cleaning, and more particularly to a pipeline flushing device. BACKGROUND

[0002] Drainage pipelines are one of the indispensable infrastructures in cities. During long-term service, the sediments in the pipelines will accumulate more and more, including pipeline fragments, soil and sand introduced by pipeline damage, and particulate matter in domestic sewage, which contains a large amount of fat, protein, carbonate and other substances.

[0003] In the related art, water flows into the inspection well, and the water flow in the inspection well converges into the main pipe through the branch pipe and is transported to the sewage treatment plant through the main pipe for treatment. Since the inner diameter of the branch pipe is smaller than that of the main pipe, the branch pipe has a higher probability of sedimentation of pollutants than the main pipe. These sediments will deposit at the bottom of the drainage pipeline when the hydraulic conditions are poor, and the sediments will form a hardened sediment layer that is difficult to clean under the effect of consolidation, which seriously affects the drainage of the city.

DETAILED DESCRIPTION

[0049] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative modifications and embodiments as would be apparent to those of ordinary skill in the art. It is to be understood that features illustrated or described as part of one embodiment can be provided with one or more of the other embodiments as would be apparent to those of ordinary skill in the art.

It is to be understood that the use of the terms so termed is interchangeable under appropriate circumstances such that the descriptive

[0051] The words "example" or "exemplary" are used herein to mean serving as an example, instance, or illustration. Any implementation described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations. The described

[0052] The inspection well 70 is used to collect sewage, the water flow flows into the inspection well 70, and the water flow in the inspection well 70 flows into the branch pipe and is transported to the sewage treatment plant through the main pipe 50 for treatment. Since the inner diameter of the branch pipe is small, when the water flow is weak, the sediment in the water flow is easy to adhere to the inner wall of the branch pipe, and the sediment forms a hardened sediment layer which is difficult to clean under the effect of consolidation, thereby affecting the drainage of the city.

[0053] Based on this, the embodiment of the present application provides a pipeline scouring device. The floating component group can move vertically in the inspection well 70. When the water level in the inspection well 70 is low, the floating component group is subjected to the gravity of itself and moves downward in the inspection well 70, pulls the gate pull rope 310, and the end of the gate pull rope 310 away from the floating component group pulls the gate door plate 500, so that the gate door plate 500 rotates relative to the support 100, thereby closing the through hole 110, and further preventing the water flow in the inspection well 70 from flowing out to the branch pipe through the through hole 110. When the water flow in the inspection well 70 increases, the floating component group is subjected to the water flow buoyancy and gradually moves upward in the inspection well 70. At this time, the gate pull rope 310 is relaxed, the gate door plate 500 rotates relative to the support 100, thereby opening the through hole 110, and a large amount of water flow rushes into the branch pipe at a moment, the impact force of the water flow is large, and the sediment in the branch pipe is scoured into the main pipe 50, thereby reducing the possibility that the sediment in the branch pipe adheres to the inner wall of the branch pipe.

[0054] As shown in FIGS. 1-8, the present application provides a pipeline flushing device, comprising a bracket 100, a gate door plate 500, a linkage assembly 200 and a gate locking assembly 300.

[0055] The bracket 100 is arranged in the inspection well 70, and a through hole 110 for connecting the branch pipe is arranged on the bracket 100.

[0056] The gate door plate 500 is connected to one side of the bracket 100.

[0057] The linkage assembly 200 comprises a floating component group, which is slidingly arranged on the side of the bracket 100 away from the gate door plate 500.

[0058] The gate locking assembly 300 comprises a gate cable 310, one end of which is connected to the floating component group, and the other end of which passes through the bracket 100 and is connected to the gate door plate 500.

[0059] The floating component group is configured to move upward relative to the bracket 100 under the buoyancy of water in the inspection well 70, drive the gate door plate 500 to rotate relative to the bracket 100 through the gate cable 310, and open the through hole 110; and move downward relative to the bracket 100 under the action of the water level in the inspection well 70 and its own gravity, drive the gate door plate 500 to rotate in the opposite direction relative to the bracket 100 through the gate cable 310, and close the through hole 110.

[0060] In the embodiment of the present application, the gate door plate 500 is arranged on one side of the branch pipe, and is rotatably connected to the bracket 100. The gate door plate 500 can be rotatably connected to the bracket 100 through a pin shaft or a hinge, so that the gate door plate 500 can close or open the through hole 110, thereby achieving the isolation and connection between the branch pipe and the inspection well 70.

[0061] Referring to FIGS. 1 and 2, the bracket 100 is provided with a through hole 120 for the gate cable 310 to pass through, and the through hole 120 is arranged at the upper part of the through hole 110. The floating component group is arranged in the inspection well 70, and the gate door plate 500 is arranged in the branch pipe. The arrangement of the through hole 110 facilitates the connection of the gate cable 310 with the gate door plate 500 and the floating component group.

[0062] Referring to FIGS. 5 and 7, the floating assembly can move vertically in the inspection well 70. When the water level in the inspection well 70 is low, the floating assembly is subjected to its own gravity and moves downward in the inspection well 70, pulling the gate pull cable 310, which pulls the gate panel 500 away from the end of the floating assembly, so that the gate panel 500 rotates relative to the bracket 100, thereby closing the through hole 110, and preventing the water flow in the inspection well 70 from flowing out of the through hole 110 into the branch pipe. When the water flow in the inspection well 70 increases, the floating assembly is subjected to the water flow buoyancy and gradually moves upward in the inspection well 70 (in the +Y direction in FIG. 2), at which time the gate pull cable 310 is relaxed, and the gate panel 500 rotates relative to the bracket 100, thereby opening the through hole 110, and a large amount of water flow rushes into the branch pipe, and the impact force of the water flow is large, which can flush the sediment in the branch pipe into the main pipe 50 connected to the branch pipe, thereby reducing the possibility of the sediment in the branch pipe adhering to the inner wall of the branch pipe.

[0063] Referring to FIG. 6, when the water level in the inspection well 70 is low, the water flow is intercepted in the inspection well 70 for storage, and until the floating assembly moves upward to open the through hole 110, the accumulated water flow can flow into the branch pipe through the through hole 110. Since the water flow after storage is large, the water flow enters the branch pipe at a faster speed, so that the sediment is not easy to consolidate in the branch pipe, thereby reducing the possibility of the branch pipe being blocked.

[0064] It should be noted that FIG. 4 is a use state diagram of the pipeline flushing device in the embodiment of the present application. As shown in FIG. 4, in use, the branch pipes connected to the main pipe 50 are divided into normal operation branch pipes 30 and poor water condition branch pipes. The connection points between the normal operation branch pipes 30, the poor water condition branch pipes, and the main pipe 50 are intersection nodes 20. The normal operation branch pipes 30 and the poor water condition branch pipes are distributed in the pollution receiving area 60, and the normal operation branch pipes 30 and the poor water condition branch pipes have inspection wells 70 provided with the pipeline flushing device. The pipeline flushing device in the above embodiment is dispersedly arranged in the inspection well 70 downstream of the community sewage outlet 10 and upstream of the poor water condition branch pipe 40, thereby forming a distributed pipeline flushing system from the community sewage outlet 10 to the main sewage pipe 50, and effectively flushing and transporting the sediment in the pollution receiving area 60 of the main pipe 50 receiving sewage, gradually transporting the sediment to the main pipe 50, and entering the sewage treatment plant with the water flow, thereby reducing the frequency of dredging the poor water condition branch pipe, reducing the sedimentation of the sediment, slowing down the consolidation of the sediment layer, and helping to improve the inflow concentration of the sewage treatment plant.

[0065] In the pipeline flushing device in the embodiment of the present application, the linkage assembly 200 further includes a connecting rod 230, a first sliding rail 240, and a second sliding rail 250. The first sliding rail 240 and the second sliding rail 250 are arranged on the bracket 100 and located on both sides of the through hole 110, respectively

[0066] The floating member group comprises a first floating member 210 slidingly arranged on the first sliding rail 240 and a second floating member 220 slidingly arranged on the second sliding rail 250, the first floating member 210 and the second floating member 220 are connected through the connecting rod 230, and the gate pull cable 310 is connected with the connecting rod 230.

[0067] Referring to FIG. 2, in the embodiment, the first sliding rail 240 and the second sliding rail 250 are arranged in parallel on both sides of the through hole 110, and a sliding member (not shown in the figure) is slidingly arranged on each of the first sliding rail 240 and the second sliding rail 250, the first floating member 210 and the second floating member 220 are connected to the corresponding sliding members, and the volume of the first floating member 210 and the second floating member 220 is greater than that of the sliding member, thereby enhancing the contact surface of the first floating member 210, the second floating member 220 and water, so as to improve the buoyancy of the first floating member 210 and the second floating member 220.

[0068] The one end of the connecting rod 230 is hinged to the first floating member 210, and the other end is hinged to the second floating member 220, and the connecting rod 230 can be a telescopic rod. The connecting rod 230 can move together with the first floating member 210 and the second floating member 220, so as to tighten or relax the gate pull cable 310.

[0069] For example, the first floating member 210 and the second floating member 220 can be hollow floats, buoys, floating plates or floating balls, etc., which have a certain mass and can naturally fall along the first sliding rail 240 and the second sliding rail 250 and float in water.

[0070] In a possible embodiment, two sliding grooves are formed on the support 100, and the first floating member 210 and the second floating member 220 can slide in the corresponding sliding grooves respectively, so that the floating member group can slide in the vertical direction of the support 100.

[0071] It can be understood that when the first floating member 210 and the second floating member 220 are respectively sliding down the first sliding rail 240 and the second sliding rail 250 under the action of their own gravity, the connecting rod 230 moves downward together to pull the gate pull cable 310 to drive the gate door plate 500 to rotate along the rotating shaft to close the through hole 110; when the first floating member 210 and the second floating member 220 are lifted relative to the support 100 by the buoyancy, the gate pull cable 310 is relaxed, and the gate door plate 500 rotates relative to the support 100 to open the through hole 110.

[0072] In the pipeline scouring device in the embodiment of the application, further comprising:

[0073] The connecting assembly 400 is installed on the support 100, and is connected with the first floating member 210. The connecting assembly 400 is connected with the second floating member 220 after the gate door plate 500 is opened to the through hole 110, so as to fix the second floating member 220.

[0074] In the pipeline flushing device, the connecting assembly 400 comprises:

[0075] The connecting member 410 is rotatably connected to the support 100, and the connecting portion 420 is arranged on the second floating member 220.

[0076] The positioning cable 430 is connected to the connecting member 410 at one end, and is connected to the first floating member 210 at the other end.

[0077] When the floating member group moves upward relative to the support 100 to the first preset position, the connecting member 410 is clamped with the connecting portion 420, and the positioning cable 430 is relaxed.

[0078] The first floating member 210 is configured to drive the positioning cable 430 to be tight when moving downward relative to the support 100 to the second preset position, and drive the connecting member 410 to rotate relative to the support 100 through the positioning cable 430, so that the connecting member 410 is disengaged from the clamping of the connecting portion 420.

[0079] The second floating member 220 is configured to move downward to the second preset position under the weight of the second floating member 220 when the connecting member 410 is disengaged from the clamping of the connecting portion 420.

[0080] In the embodiment, the first preset position can be the top of the first sliding rail 240, and the second preset position can be the bottom of the first sliding rail 240. When the first floating member 210 and the second floating member 220 rise to the first preset position together with the buoyancy, the gate door plate 500 is opened, the positioning cable 430 is relaxed, the connecting member 410 is clamped with the connecting portion 420, and the connecting member 410 fixes the second floating member 220, so that the through hole 110 is kept in an open state, and the water flow is discharged from the through hole 110 into the branch pipe.

[0081] Referring to FIG. 8, when the water flow in the inspection well 70 is discharged, the first floating member 210 moves downward under the action of its own gravity, and the second floating member 220 is fixed by the connecting member 410 and does not change in position. Since the distance between the first floating member 210 and the second floating member 220 is increased, the connecting rod 230 is elongated, and the middle part of the connecting rod 230 is located between the first preset position and the second preset position. At this time, the through hole 110 is kept in an open state.

[0082] When the first floating member 210 moves downward to the second preset position, the positioning cable 430 is pulled tight, the positioning cable 430 drives the connecting member 410 to rotate relative to the support 100, so that the connecting member 410 is disengaged from the connecting part 420, and the second floating member 220 moves downward on the second sliding track 250 under the action of gravity. Referring to FIG. 5, when the second floating member 220 moves downward to the second preset position, the connecting rod 230 pulls the gate cable 310 to drive the gate door plate 500 to close the through hole 110, so that the inspection well 70 enters the water storage state.

[0083] Further, the connecting assembly 400 further comprises a reset member 440, one end of the reset member 440 is connected with the connecting member 410, and the other end of the reset member 440 is connected on the support 100.

[0084] The reset member 440 is configured to stretch and drive the connecting member 410 to rotate relative to the support 100 towards the direction of the positioning cable 430 when the connecting member 410 is disengaged from the connecting part 420. In the embodiment, the reset member 440 is a spring.

[0085] Referring to FIG. 8, it can be understood that when the first floating member 210 and the second floating member 220 are floated upward to open the through hole 110 under the action of the water flow floating force, the water flow in the inspection well 70 flows into the branch pipe, the positioning cable 430 is relaxed, the reset member 440 is in a free state, the first floating member 210 and the second floating member 220 are located at the first preset position, the connecting member 410 is engaged with the connecting part 420, and the connecting member 410 thus plays a fixing role on the second floating member 220, reducing the possibility of the second floating member 220 moving downward on the second sliding track 250;

[0086] When the water level in the inspection well 70 decreases, the first floating member 210 moves downward on the first sliding track 240 following the water flow, and the second floating member 220 does not change in position due to the pulling force of the connecting member 410, at this time the connecting rod 230 is elongated. When the first floating member 210 moves to the second preset position, the positioning cable 430 is straightened, the water level continues to decrease to below the first floating member 210, the first floating member 210 loses the water floating force, and the first floating member 210 stretches the reset member 440 by the action of gravity, so that the connecting member 410 rotates towards the direction of the positioning cable 430 and is disengaged from the connecting part 420. After the second floating member 220 loses the fixing role of the connecting member 410, the second floating member 220 moves downward on the second sliding track 250, and when the second floating member 220 moves to the second preset position, the connecting rod 230 pulls the gate cable 310 to make the gate door plate 500 completely close the through hole 110.

[0087] In the pipeline flushing device, the connecting assembly 400 further comprises a first pulley 450, the first pulley 450 is rotationally arranged on the support 100, and the positioning cable 430 is arranged around the first pulley 450.

[0088] In the pipeline flushing device, the door locking assembly 300 further comprises a second pulley 320, the second pulley 320 is arranged on the top of the support 100, and the gate cable 310 is arranged around the second pulley 320.

[0089] The first pulley 450 and the second pulley 320 are arranged to prevent the gate cable 310 and the positioning cable 430 from being crossed and wound during movement.

[0090] In the pipeline flushing device, the door locking assembly 300 further comprises a gate unlocking lock 330 and a trigger 340, the support 100 is fixedly connected with two parallel sliding seats 350, and two ends of the trigger 340 are slidingly arranged in the corresponding sliding seats 350.

[0091] The trigger 340 is configured to be driven by the connecting rod 230 to move upwards relative to the sliding seat 350 and contact the gate unlocking lock 330, so that the gate unlocking lock 330 unlocks the gate plate 500.

[0092] The gate unlocking lock 330 is configured to be connected with the support 100 when the gate plate 500 closes the through hole 110, so as to lock the gate plate 500 on the support 100.

[0093] Referring to FIG. 3, in the pipeline flushing device, the trigger 340 is fixedly connected with a baffle 360 on the side away from the support 100, when the connecting rod 230 moves upwards relative to the support 100, the baffle 360 abuts against the connecting rod 230 and pushes the trigger 340 to move upwards, so that the trigger 340 contacts the gate unlocking lock 330.

[0094] In the pipeline flushing device, the gate unlocking lock 330 is a spring pressing lock.

[0095] It can be understood that when the floating group moves up to the first preset position, the connecting rod 230 pushes the baffle 360, so that the trigger 340 slides in the sliding seat 350, and when the trigger 340 moves to contact the gate lock 330 in the sliding seat 350, the gate lock 330 unlocks the gate plate 500, so that the gate plate 500 opens the through hole 110, and the water flow in the inspection well 70 flows into the branch pipe. The arrangement of the gate lock 330 can make the gate plate 500 open the through hole 110 only when the water level in the inspection well 70 rises to the first preset height, which guarantees the water storage capacity of the inspection well 70, so that when the through hole 110 is opened, the flow rate of the water flow in the branch pipe can scour the sediment, reducing the possibility of the sediment in the branch pipe adhering to the inner wall of the branch pipe.
