Description

Technical Field

[0001] The invention relates to a long-distance environmentally friendly dredging pipeline on a water surface and an installation method thereof, belonging to the technical field of dredging construction. Background Art

[0002] Conventional dredging pipes used for surface dredging mostly use flexible pipes to make them float on the water surface to avoid being corroded by being immersed in water for a long time. However, the flexible pipes shake greatly when floating on the water surface, which is not conducive to the passage of silt. At the same time, when the pipeline is completed, the water surface cannot pass ships. When ships need to pass, the pipeline needs to be dismantled, so it is more cumbersome to use. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a long-distance environmentally friendly dredging pipeline on the water surface and an installation method, which solves the problem in the prior art that the flexible pipeline has a large shaking amplitude when floating on the water surface, which is not conducive to the passage of silt. At the same time, when the pipeline is completed, the water surface cannot pass ships. When ships need to pass, the pipeline needs to be dismantled, so it is cumbersome to use.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: a long-distance environmental protection dredging pipeline on the water surface, comprising

[0005] The metal dredging pipeline extends on the water surface, and is surrounded by a number of floating objects.

[0006] Flexible dredging pipeline, connected and installed at both ends of the metal dredging pipeline,

[0007] The connector is surrounded and fixed in the middle of the metal dredging pipe.

[0008] A support component is connected to the connector and is used to limit the range of movement of the metal dredging pipe. An adjustment component is provided inside the support component and a connecting rope is provided on the adjustment component. The adjustment component adjusts the vertical distance between the metal dredging pipe and the water surface by adjusting the length of the connecting rope.

[0009] By adopting the above technical scheme, the buoyancy of the floating object makes the metal dredging pipe float on the water surface. At the same time, the position of the metal dredging pipe is constrained and restricted by the supporting component to prevent the metal dredging pipe from shaking significantly under the action of the water flow. At the same time, the adjusting component can change the position of the metal dredging pipe from the water surface by changing the length of the connecting rope. When the length of the connecting rope becomes shorter, the metal dredging pipe is pulled underwater. The underwater distance is ultimately determined by the length of the flexible dredging pipe. When the flexible dredging pipe is stretched into a straight line, the metal dredging pipe cannot be further lowered. At this time, since the metal dredging pipe is underwater, small ships can pass on the water surface, so that the metal dredging pipe does not need to be temporarily dismantled and installed when the ship passes, thereby improving the convenience of using the dredging pipe.

[0010] The present invention is further configured as follows: the adjustment component comprises

[0011] Insertion body, fixed on one side of the connector,

[0012] The adjusting block is installed on the supporting assembly, and the end surface of the adjusting block facing the connecting body is provided with

[0013] The adjusting cavity is provided with a rotating

[0014] The winding wheel has one end of a connecting rope wound around it, and the other end of the connecting rope is fixedly connected to the insert body.

[0015] The adjusting motor is fixed on the outside of the adjusting block, and the adjusting motor is connected with the winding wheel power.

[0016] By adopting the above technical solution, the adjusting motor is started to drive the winding wheel to rotate forward or reverse, so that the length of the connecting rope becomes longer or shorter, thereby pulling the connecting body closer to or away from the adjusting block. Since the position of the adjusting block is fixed relative to the supporting assembly, the position of the metal dredging pipe from the water surface can be adjusted at this time, so that small boats can temporarily pass through the water surface.

[0017] The present invention is further configured as follows: the support assembly comprises

[0018] The support column is vertically arranged, and a sliding cavity with a lateral opening is vertically arranged on the support column.

[0019] The drive motor is fixed to the end of the support column close to the water surface.

[0020] The driving screw is vertically rotatably arranged in the sliding cavity, one end of the driving screw is connected to the driving motor power, and the driving screw passes through the adjusting block and is threadedly connected to the adjusting block.

[0021] By adopting the above technical solution, after the driving motor is started, it drives the driving screw to rotate forward and reversely, thereby driving the adjustment block to slide along the axis of the driving screw on the sliding cavity under the action of the threaded connection, so as to further adjust the distance range of the metal dredging pipe from the water surface, so that the metal dredging pipe can be used in places with deeper water.

[0022] The present invention is further configured as follows: a drainage channel is provided on one end wall of the regulating cavity away from the opening, the other end of the drainage channel passes through from below the regulating block, the inner wall of the regulating cavity can slide and abut against the outer wall of the insert body and the abutment is sealed.

[0023] By adopting the above technical solution, when the connecting rope is gradually wound onto the winding wheel, the insert body is slowly inserted into the regulating chamber. At this time, the internal pressure of the regulating chamber becomes larger, and the water in the regulating chamber is pressed out through the sewage channel. In this process, the water in the regulating chamber is disturbed, and while being pressed out, some foreign matter attached to the inner wall of the regulating chamber can be taken away, thereby achieving the purpose of preliminary cleaning of the inner wall of the regulating chamber.

[0024] The present invention is further configured as follows: a curved body is provided at the bottom of the sliding cavity, the curved body is used to limit the movement of the adjustment block along the extension direction of the sliding cavity and at the same time make foreign matter in the sliding cavity slide out of the sliding cavity along the surface of the curved body under the action of gravity.

[0025] By adopting the above technical solution, after the water carrying foreign matter is sprayed out from the sewage channel, it moves to the bottom of the sliding cavity under the action of inertia and gravity. At this time, after the foreign matter contacts the surface of the curved body, the foreign matter is moved to the outside of the sliding cavity under the action of the inclination of the curved body. At the same time, the adjusting block can avoid contact with the inclined surface of the curved body, thereby avoiding the foreign matter being stuck between the adjusting block and the bottom of the sliding cavity and damaging the support column during the movement of the adjusting block.

[0026] The present invention is further configured as follows: a water-filled bag is fixedly mounted on the open end of the regulating cavity, the water-filled bag extends toward the inner side of the regulating cavity opening, and the edge of one end of the insert away from the connector is rounded.

[0027] By adopting the above technical solution, the water-filled bag can further fill the gap when the rounded corner of the insert body is inserted into the adjustment cavity, thereby further improving the sealing of the connection when the insert body is inserted into the adjustment cavity.

[0028] The present invention is further configured as follows: a water supply block is fixedly arranged on the regulating block, a working chamber is provided in the water supply block, a connecting shaft is rotatably arranged in the working chamber, a rotating wheel is fixed at one end of the connecting shaft away from the regulating chamber, a connecting rod is hinged at the eccentric end of the rotating wheel, a pressing block is hinged at the other end of the connecting rod, the pressing block is linearly slidably arranged in the working chamber, the pressing block is in contact with the inner wall of the working chamber and the contact is sealed, a water supply pipe and a water inlet pipe are provided in the working chamber on the side away from the rotating wheel in the sliding direction of the pressing block, one end of the water supply pipe is communicated with the water filling bag, one end of the water inlet pipe passes through the water supply block and is communicated with the outside of the water supply block, a one-way valve is fixed in the water supply pipe and the water inlet pipe, a driven shaft connected to the power of the regulating motor and located at the eccentric axial direction of the regulating motor is rotatably arranged in the regulating chamber, the driven shaft is power-connected to the regulating motor through a group of gear pairs, the driven shaft and the connecting shaft are coaxially arranged, and a switching structure for intermittently connecting the driven shaft and the connecting shaft is connected between the driven shaft and the connecting shaft.

[0029] The present invention is further configured as follows: the switching structure includes

[0030] The switching cavity is opened in the adjusting block, and the ends of the connecting shaft and the driven shaft extend into the switching cavity.

[0031] The magnetic plate is slidably arranged along the axial direction of the driven shaft.

[0032] The intermediate shaft is rotatably arranged in the magnetic plate, and both ends of the intermediate shaft can be spline-connected with the connecting shaft and the driven shaft.

[0033] The electromagnet is fixed on the end wall of the switching chamber along the axial direction of the driven shaft.

[0034] The return spring is arranged on the side of the magnetic attraction plate opposite to the electromagnet.

[0035] By adopting the above technical scheme, when the electromagnet is energized, the magnetic attraction plate is attracted. At this time, the intermediate shaft and the driven shaft are disconnected, and the driven shaft cannot transmit power to the connecting shaft. When the electromagnet is de-energized, the intermediate shaft and the driven shaft are splined under the elastic action of the reset spring. At this time, the driven shaft transmits power to the connecting shaft through the intermediate shaft, so that the connecting shaft drives the connecting rod to rotate. Since the two ends of the connecting rod are hinged, and the rotating wheel drives one end of the connecting rod to make a circular motion, the pressing block slides linearly in the working chamber. The inner wall of the working chamber and the pressing block form a closed space. When the pressing block moves away from the inner wall of the working chamber, the air pressure in the closed space decreases, and external water enters the closed space of the working chamber through the water inlet pipe and the one-way valve. When the pressing block moves close to the inner wall of the working chamber, the air pressure in the closed space increases. At the same time, the water in the closed space is pressed into the water filling bag through the water supply pipe and the one-way valve to expand the water filling bag, thereby further filling the gap between the insertion body and the inner wall of the adjustment chamber, and further avoiding the sealing of the connection between the insertion body and the adjustment chamber.

[0036] The present invention is further configured as follows: two winding wheels are provided and are located in the same horizontal plane, and one of the winding wheels is fixed on the driven shaft.

[0037] By adopting the above technical solution, two winding wheels are used to balance the two ends of the insert when the insertion body is subjected to the tension of the connecting rope, thereby improving the stability of the metal dredging pipe after being pulled under the water surface.

[0038] A method for installing a long-distance environmental protection dredging pipeline on a water surface, comprising:

[0039] S1: Fix the support assembly to the riverbed under the water surface;

[0040] S2: Connecting the two ends of the metal dredging pipe to the flexible dredging pipes located on the river surface and the river bank respectively;

[0041] S3: The control adjustment component adjusts the length of the connecting rope so that the metal dredging pipe floats on the water surface under the buoyancy of the floating objects.

[0042] The beneficial effects of the present invention are:

[0043] 1. The buoyancy of the floating objects makes the metal dredging pipe float on the water surface. At the same time, the position of the metal dredging pipe is constrained and restricted by the support components to prevent the metal dredging pipe from shaking significantly under the action of the water flow.

[0044] 2. The adjustment component can change the position of the metal dredging pipe from the water surface by changing the length of the connecting rope. When the length of the connecting rope becomes shorter, the metal dredging pipe is pulled underwater. The distance pulled underwater is ultimately determined by the length of the flexible dredging pipe. When the flexible dredging pipe is stretched into a straight line, the metal dredging pipe cannot be further lowered. At this time, since the metal dredging pipe is underwater, small ships can pass on the water surface, so that the metal dredging pipe does not need to be temporarily dismantled and installed when the ship passes, thereby improving the convenience of using the dredging pipe.

DETAILED DESCRIPTION

[0053] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0054] like Figure 1-7As shown, a long-distance environmentally friendly dredging pipeline on the water surface and an installation method thereof include a metal dredging pipeline 10, a flexible dredging pipeline 11, a connector 13, a support assembly and an adjustment assembly. The metal dredging pipeline 10 extends from the river channel to the river bank on the water surface. The metal dredging pipeline 10 is surrounded by a plurality of floating objects 12. The flexible dredging pipeline 11 is connected and arranged at both ends of the metal dredging pipeline 10. The flexible dredging pipeline 11 at one end of the metal dredging pipeline 10 is connected to a dredging ship, and the flexible dredging pipeline 11 at the other end of the metal dredging pipeline 10 is connected to a dredging pipeline on the river bank. The connector 13 is surrounded and fixedly arranged in the middle of the metal dredging pipeline 10. The support assembly is connected to the connector 13. The support assembly is used to limit the range of movement of the metal dredging pipeline 10. An adjustment assembly is arranged in the support assembly. A connecting rope 26 is arranged on the adjusting assembly. The adjusting assembly adjusts the vertical distance between the metal dredging pipeline 10 and the water surface by adjusting the length of the connecting rope 26. The adjustment assembly includes an insert 14, an adjustment block 24 and an adjustment motor 27. The insert 14 is fixed to one side of the connecting body 13. The adjustment block 24 is installed on the support assembly. An adjustment cavity 29 is provided on one end face of the adjustment block 24 facing the connecting body 13. A winding wheel 40 is rotatably arranged in the adjustment cavity 29. One end of the connecting rope 26 is wound around the winding wheel 40, and the other end of the connecting rope 26 is fixedly connected to the insert 14. The adjustment motor 27 is fixed to the outside of the adjustment block 24, and the adjustment motor 27 is connected to the winding wheel 40. The support assembly includes a support column 20, a drive motor 22 and a drive screw 23. The support column 20 is vertically arranged, that is, vertically arranged to the horizontal plane, and one end of the support column 20 is inserted into the riverbed and fixed. A sliding cavity 21 with a side opening is vertically arranged on the support column 20, and a curved body 28 is arranged at the bottom of the sliding cavity 21. The curved body 28 is used to limit the movement of the adjustment block 24 along the extension direction of the sliding cavity 21 and make the foreign matter in the sliding cavity 21 slide out of the sliding cavity 21 along the surface of the curved body 28 under the action of gravity. The driving motor 22 is fixed at one end of the support column 20 close to the water surface. The driving screw 23 is vertically rotatably arranged in the sliding cavity 21, one end of the driving screw 23 is connected to the driving motor 22, and the driving screw 23 passes through the adjustment block 24 and is threadedly connected to the adjustment block 24.

[0055] like Figure 3-6As shown, a drainage channel 48 is provided on the end wall of the regulating chamber 29 away from the opening, and the other end of the drainage channel 48 passes through the bottom of the regulating block 24. The inner wall of the regulating chamber 29 can slide and abut with the outer wall of the insert body 14 and the abutment is sealed. A water bag 50 is fixedly installed at the end of the opening of the regulating chamber 29, and the water bag 50 extends toward the inner side of the opening of the regulating chamber 29. When the water bag 50 is installed, there is a gap between the insert body 14 and the inner wall of the regulating chamber 29 to provide a space for the water bag 50 to be stored. A drainage channel 51 connected to the water bag 50 is provided in the regulating block 24, and the other end of the drainage channel 51 passes through the regulating block 24 and is connected to the outside of the regulating block 24. A one-way pressure valve 52 is fixed in the drainage channel 51, and the one-way pressure valve 52 can only allow the liquid and gas in the water bag 50 to flow to the outside of the water bag 50. The edge of the end of the insert body 14 away from the connecting body 13 is rounded. When the insert body 14 is inserted into the regulating cavity 29, due to the rounded corners of the insert body 14, the insert body 14 can be inserted into the regulating cavity 29 more smoothly. At the same time, the water bag 50 can fill the connecting gap between the insert body 14 and the regulating cavity 29. At the same time, as the insert body 14 is gradually inserted, the gap between the insert body 14 and the regulating cavity 29 gradually becomes smaller, thereby squeezing the part of the insert body 14 that extends to the inner side of the opening of the regulating cavity 29, so that the liquid and gas in the water bag 50 are pressed into the discharge channel 51. When the pressure difference on both sides of the one-way pressure valve 52 reaches the opening threshold of the one-way pressure valve 52, the one-way pressure valve 52 opens, and the liquid and gas in the water bag 50 are discharged through the opening of the discharge channel 51, thereby reducing the volume of the water bag 50, thereby reducing the resistance encountered by the insert body 14 when it is pulled out of the regulating cavity 29, and making the insert body 14 better pulled out.

[0056] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, a water supply block 30 is fixedly arranged on the regulating block 24, a working chamber 33 is opened in the water supply block 30, a connecting shaft 37 is rotatably arranged in the working chamber 33, a rotating wheel 34 is fixed to the end of the connecting shaft 37 away from the regulating chamber 29, a connecting rod 35 is hinged at the eccentric end of the rotating wheel 34, a pressing block 36 is hinged at the other end of the connecting rod 35, the pressing block 36 is linearly slidably arranged in the working chamber 33, the pressing block 36 is in contact with the inner wall of the working chamber 33 and the contact is sealed, and a water supply block 36 is opened in the working chamber 33 on the side away from the rotating wheel 34 in the sliding direction of the pressing block 36. A water pipe 31 and a water inlet pipe 32, one end of the water supply pipe 31 is connected to the water filling bag 50, one end of the water inlet pipe 32 passes through the water supply block 30 and is connected to the outside of the water supply block 30, a one-way valve is fixed in the water supply pipe 31 and the water inlet pipe 32, a driven shaft 42 connected to the regulating motor 27 and located in the axial direction of the regulating motor 27 is rotatably arranged in the regulating chamber 29, the driven shaft 42 and the regulating motor 27 are connected through a set of gear pairs, the gear pair is formed by meshing two spur gears 41, and the spur gears 41 are respectively fixedly connected to the output shaft of the regulating motor 27 and the driven shaft 42 as shown in FIG. Figure 6 As shown, the two power connections, the driven shaft 42 and the connecting shaft 37 are coaxially arranged, and a switching structure for intermittently connecting the driven shaft 42 and the connecting shaft 37 is connected between the driven shaft 42 and the connecting shaft 37.

[0057] like Figure 6 As shown, the switching structure includes a switching chamber 43, a magnetic plate 44, an intermediate shaft 45, a reset spring 46 and an electromagnet 47. The switching chamber 43 is opened in the adjustment block 24, and the ends of the connecting shaft 37 and the driven shaft 42 extend into the switching chamber 43. The magnetic plate 44 is slidably arranged along the axial direction of the driven shaft 42, and the intermediate shaft 45 is rotatably arranged in the magnetic plate 44. The two ends of the intermediate shaft 45 can be spline-connected with the connecting shaft 37 and the driven shaft 42. The electromagnet 47 is fixed to the end wall of the switching chamber 43 along the axial direction of the driven shaft 42, and the reset spring 46 is arranged on the side of the magnetic plate 44 opposite to the electromagnet 47. The winding wheel 40 is provided with two located in the same horizontal plane, and one of the winding wheels 40 is fixed on the driven shaft 42. Through the two winding wheels 40, the two ends of the insert 14 are balanced when the tension of the connecting rope 26 is applied, thereby improving the stability of the metal dredging pipeline 10 after being pulled under the water surface.

[0058] When the connecting rope 26 is wound around the winding wheel 40, the electromagnet 47 is not energized. When the connecting rope 26 is loosened from the winding wheel 40, the electromagnet 47 is energized, thereby achieving the purpose of inflating the water bag 50 with air or water only when the metal dredging pipe 10 enters the water from the water surface, avoiding the situation in which the water bag 50 is filled with air and water when the metal dredging pipe 10 floats up.

[0059] The use of the metal desilting pipe 10 can avoid the situation where the flexible desilting pipe 11 is used exclusively and the flexible desilting pipe 11 is corroded and damaged after long-term use, thereby increasing the service life.

[0060] Under the buoyancy of the floating object 12, the metal dredging pipe 10 floats on the water surface. At the same time, the position of the metal dredging pipe 10 is constrained and restricted by the supporting component to prevent the metal dredging pipe 10 from shaking significantly under the action of the water flow. At the same time, the adjusting component can change the position of the metal dredging pipe 10 from the water surface by changing the length of the connecting rope 26. When the length of the connecting rope 26 becomes shorter, the metal dredging pipe 10 is pulled underwater. The underwater distance is ultimately determined by the length of the flexible dredging pipe 11. When the flexible dredging pipe 11 is stretched into a straight line, the metal dredging pipe 10 cannot drop further. At this time, since the metal dredging pipe 10 is underwater, small ships can pass through the water surface, so that the metal dredging pipe 10 does not need to be temporarily dismantled and installed when the ship passes, thereby improving the convenience of using the dredging pipe.

[0061] The adjusting motor 27 is started to drive the winding wheel 40 to rotate forward or reversely, thereby lengthening or shortening the length of the connecting rope 26, thereby pulling the connecting body 13 close to or away from the adjusting block 24. Since the position of the adjusting block 24 is fixed relative to the supporting assembly, the position of the metal dredging pipe 10 from the water surface can be adjusted at this time, so that the water surface can temporarily pass small boats. After the driving motor 22 is started, it drives the driving screw 23 to rotate forward and reversely, thereby driving the adjusting block 24 to slide along the axis of the driving screw 23 on the sliding cavity 21 under the action of the threaded connection, so that the distance range of the metal dredging pipe 10 from the water surface can be further adjusted, so that the metal dredging pipe 10 can be used in places with deeper water depths.

[0062] When the connecting rope 26 is gradually wound onto the winding wheel 40, the insert body 14 is slowly inserted into the adjusting chamber 29. At this time, the internal pressure of the adjusting chamber 29 increases, and the water in the adjusting chamber 29 is pressed out through the sewage channel 48. In this process, the water in the adjusting chamber 29 is disturbed, and while being pressed out, some foreign matter attached to the inner wall of the adjusting chamber 29 can be taken away, thereby achieving the purpose of preliminarily cleaning the inner wall of the adjusting chamber 29.

[0063] After the water carrying foreign matter is sprayed out from the sewage channel 48, it moves toward the bottom of the sliding cavity 21 under the action of inertia and gravity. At this time, the foreign matter contacts the surface of the curved body 28 and is moved to the outside of the sliding cavity 21 due to the slope of the curved body 28. At the same time, the adjustment block 24 can avoid contacting the slope of the curved body 28, thereby preventing the foreign matter from being stuck between the adjustment block 24 and the bottom of the sliding cavity 21 and damaging the support column 20 during the movement of the adjustment block 24.

[0064] The water-filled bag 50 can further fill the gap when the fillet of the insert 14 is inserted into the adjusting cavity 29, thereby further improving the sealing degree of the connection when the insert 14 is inserted into the adjusting cavity 29. When the electromagnet 47 is energized, it attracts the magnetic plate 44. At this time, the intermediate shaft 45 is disconnected from the driven shaft 42, and the driven shaft 42 cannot transmit power to the connecting shaft 37. When the electromagnet 47 is powered off, the intermediate shaft 45 is pulled to be spline-connected with the driven shaft 42 under the elastic action of the reset spring 46. At this time, the driven shaft 42 transmits power to the connecting shaft 37 through the intermediate shaft 45, so that the connecting shaft 37 drives the connecting rod 35 to rotate. Since the two ends of the connecting rod 35 are hinged, and the rotating wheel 34 drives one end of the connecting rod 35 to make a circular motion, the pressing block 36 slides linearly in the working cavity 33, and the working The inner wall of the working chamber 33 and the pressing block 36 form a closed space. When the pressing block 36 moves away from the inner wall of the working chamber 33, the air pressure in the closed space decreases, and external water enters the closed space of the working chamber 33 through the water inlet pipe 32 and the one-way valve. When the pressing block 36 moves toward the inner wall of the working chamber 33, the air pressure in the closed space increases, and at the same time, the water in the closed space is pressed into the water filling bag 50 through the water supply pipe 31 and the one-way valve to expand the water filling bag 50, thereby further filling the gap between the insert body 14 and the inner wall of the regulating chamber 29, further avoiding the sealing of the connection between the insert body 14 and the regulating chamber 29.
