Description

Technical Field

[0001] The present invention relates to the technical field of dredging, and particularly to a Yellow River dredging and sediment discharging platform. Background Art

[0002] The Yellow River contains a large amount of sediment, and the river channel will quickly silt up. In order to restore the normal function of the Yellow River channel, dredging and sediment discharging are required. A variety of river channel dredging and sediment discharging platforms and devices have been disclosed in the prior art. For example, the vortex gas disturbance estuary fine particle sediment dredging device and dredging method proposed in the Chinese invention patent with the publication number of CN107724449B connect a vertical air inlet pipeline with a vortex gas disturbance component, and an external air compressor passes high-pressure gas into the vortex gas disturbance component through this air inlet pipeline. The high-pressure gas enters each air chamber of the vortex gas disturbance component and then sprays out from the nozzle. The spraying direction is directly opposite to the 45° air guiding inclined plane, and this inclined plane ejects the gas upward, driving the water body containing fine particle sediment to move upward as well, disturbing and dredging the estuary fine particle sediment.

[0003] The above-mentioned existing dredging device transports high-pressure air to the dredging device through an external high-pressure gas system, so that the high-pressure air impacts the silt at the bottom of the river channel, and the silt is disturbed and then dredged. However, when the water depth of the river channel is relatively large, a relatively large air pressure is required, and the requirement for the external high-pressure gas system is relatively high. Moreover, the disturbed and dredged silt directly diffuses into the river water, which is not conducive to discharging the sediment out of the river channel. Therefore, improvement is needed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a Yellow River dredging and sediment discharging platform, which exhausts and breaks the sediment by inserting a blasting air pipe into the sediment, concentrates the sediment and then discharges it, improving the sediment discharging efficiency and having good practicability.

[0005] To achieve the above object, the present invention provides a Yellow River dredging and sand discharging platform, which includes a floating box; it also includes a mud box, a blasting air pipe, an electromagnetic coil I, an electromagnetic coil II, a magnet piston, an air inlet pipe, a sling mechanism and a sand discharging mechanism. A chamber is arranged inside the mud box, and a lower opening communicating with the chamber is arranged on the lower end surface of the mud box. The mud box is suspended below the floating box through the sling mechanism. The blasting air pipe is vertically installed in the chamber of the mud box. The upper end of the blasting air pipe is closed, and an air outlet is arranged at the lower end. A one-way pressure limiting valve is installed in the air outlet of the blasting air pipe. The electromagnetic coil I is sleeved on the upper part of the blasting air pipe, and the electromagnetic coil II is sleeved on the lower part of the blasting air pipe. The magnet piston is slidably installed inside the blasting air pipe. The upper end of the air inlet pipe extends out of the water surface, and the lower end of the air inlet pipe is connected to the inside of the blasting air pipe. A one-way valve is installed in the lower end of the air inlet pipe. The sand discharging mechanism is installed on the mud box and is used to discharge the sediment in the chamber of the mud box. During operation, the floating box moves to the dredging position, the mud box is released to the bottom of the river through the sling mechanism, and the edge of the lower opening of the mud box shovels into the sediment. The air outlet of the blasting air pipe is inserted into the sediment. The electromagnetic coil I is energized to generate a magnetic force to attract the magnet piston to the upper part of the blasting air pipe. The outside air is input into the inside of the blasting air pipe through the air inlet pipe. The electromagnetic coil I switches the energized circuit to reverse the magnetic pole to repel the magnet piston. At the same time, the electromagnetic coil II is energized to attract the magnet piston, so that the magnet piston quickly moves to the lower part of the blasting air pipe, thereby compressing the air inside the blasting air pipe by the magnet piston. When the air pressure in the blasting air pipe reaches the threshold value of the one-way pressure limiting valve, it is quickly discharged through the air outlet. The discharged air impacts and breaks the sediment at the bottom of the river. Repeating the above actions makes the blasting air pipe continuously spray air to break the sediment at the bottom of the river. The broken sediment is covered by the mud box in the chamber and will not spread into the river water. The sand discharging mechanism operates to discharge the sediment in the mud box. Compared with the prior art, the external high-pressure air system is cancelled, the air supply pressure is not affected by the water depth of the river, and the disturbed and dredged silt is covered and concentrated by the mud box and then discharged, and will not spread into the river water, which is beneficial to discharging the sediment out of the river.

[0006] Preferably, it further includes a gas tank box, a gas pipe, an air pipe, a mixing box and a spark plug. The gas pipe and the mixing box are installed on the floating box. A gas tank and an air tank are arranged inside the gas tank box. The two ends of the gas pipe are respectively connected to the gas tank and the input end of the mixing box. The two ends of the air pipe are respectively connected to the air tank and the input end of the mixing box. The upper end of the air inlet pipe is connected to the output end of the mixing box, and the spark plug is installed at the lower end inside the blasting air pipe. The gas in the gas tank in the gas tank box is input into the mixing box through the gas pipe, and the air in the air tank is input into the mixing box through the air pipe. The gas and the air are mixed in the mixing box, and the mixed gas is input into the inside of the blasting air pipe through the air inlet pipe. After the mixed gas is compressed by the magnet piston, the spark plug ignites to detonate the compressed mixed gas, thereby generating deflagration gas with greater pressure and impact force. The deflagration gas is discharged through the air outlet of the blasting air pipe to impact and break the sediment at the bottom of the river, improving the breaking effect on the sediment at the bottom of the river.

[0007] Preferably, it further includes a plurality of cutting knives, and a plurality of cutting knives are installed on the outer wall of the lower end of the blasting air pipe; after the lower end of the blasting air pipe is inserted into the sediment, the plurality of cutting knives shovel into the sediment, so as to cut the sediment and improve the crushing efficiency of the sediment.

[0008] Preferably, it further includes a guide rod and a first spring. The guide rod is installed at the upper end of the blasting air pipe. The guide rod is slidably inserted into the cross beam at the upper part of the chamber of the mud box. The upper end of the first spring is connected to the cross beam, and the lower end of the first spring is connected to the blasting air pipe; the sliding insertion of the guide rod and the cross beam of the mud box limits and guides the blasting air pipe. The elastic force of the first spring pushes the blasting air pipe downward, so that the lower end of the blasting air pipe is always inserted into the sediment, ensuring the stable effect of the blasting air pipe exhausting and impacting the sediment multiple times.

[0009] Preferably, the sling mechanism includes a winch and a sling. The winch is installed on the floating box. The upper end of the sling is wound on the winch, and the lower end of the sling is connected to the mud box; the winch winds the sling to lift the mud box, and the winch releases the sling to lower the mud box, so as to adjust the depth position of the mud box and facilitate the lifting and lowering of the mud box. The technology is mature and reliable.

[0010] Preferably, the sand discharge mechanism includes a delivery pipe, an upper one-way component, a lifting pipe, a lower one-way component, an electromagnetic coil three, a sealing sleeve and an electromagnetic coil four. The delivery pipe is installed on the upper end face of the mud box. A mud discharge pipe is installed at the upper end of the delivery pipe, and the mud discharge pipe extends above the water surface. The delivery pipe communicates with the chamber of the mud box. The upper one-way component is installed at the upper end inside the delivery pipe. The lifting pipe is slidably installed at the lower end inside the delivery pipe. The lower one-way component is installed at the lower end of the lifting pipe. The electromagnetic coil three is sleeved on the outer wall of the lower end of the delivery pipe. The sealing sleeve is slidably sleeved on the upper outer wall of the delivery pipe. A chute is provided on the upper side wall of the delivery pipe. The connecting piece of the lifting pipe is connected to the sealing sleeve through the chute. The electromagnetic coil four is sleeved on the outer wall of the sealing sleeve; when it is necessary to discharge the crushed sediment in the chamber of the mud box, the electromagnetic coil three and the electromagnetic coil four are energized so that the electromagnetic coil three and the electromagnetic coil four attract each other. The electromagnetic coil four drives the lifting pipe to move downward along the delivery pipe, so that the lower part of the lifting pipe extends into the chamber of the mud box. The sediment in the chamber of the mud box enters the inside of the lifting pipe and the delivery pipe through the lower one-way component. The electromagnetic coil three and the electromagnetic coil four switch the circuit to make the electromagnetic coil three and the electromagnetic coil four repel each other, so that the electromagnetic coil four drives the lifting pipe to rise along the delivery pipe. The lower one-way component closes to cooperate with the lifting pipe to push the sediment in the delivery pipe to open the upper one-way component and push it into the mud discharge pipe above the delivery pipe. The electromagnetic coil three and the electromagnetic coil four switch the circuit to make the electromagnetic coil three and the electromagnetic coil four attract each other. The electromagnetic coil four drives the lifting pipe to move downward along the delivery pipe. The upper one-way component closes the upper end of the delivery pipe. Repeat the above actions to gradually lift the sediment in the chamber of the mud box, so as to discharge the sediment above the water surface.

[0011] Preferably, it further includes a second spring. The second spring is sleeved outside the conveying pipe. The lower end of the second spring is connected to the third electromagnetic coil, and the upper end of the second spring is connected to the fourth electromagnetic coil. The second spring elastically supports and buffers the fourth electromagnetic coil, preventing the fourth electromagnetic coil from colliding with the third electromagnetic coil and improving safety.

[0012] Preferably, the upper one-way component includes an annular seat ring, a cover plate and a third spring. The annular seat ring is installed in the conveying pipe. A sliding sleeve is arranged in the middle of the annular seat ring. A plurality of sediment through holes are arranged on the annular seat ring. A sliding rod is concentrically arranged on the lower end surface of the cover plate. The sliding rod of the cover plate is slidably inserted into the sliding sleeve of the annular seat ring. The third spring is sleeved on the sliding rod of the cover plate. The upper end of the third spring is connected to the annular seat ring, and the lower end of the third spring is connected to the lower end of the sliding rod of the cover plate. The elastic force of the third spring pulls the cover plate tightly onto the upper end surface of the annular seat ring. The lower one-way component has the same structure as the upper one-way component. The elastic force of the third spring pulls the cover plate downward, causing the cover plate to close the sediment through holes of the annular seat ring, so that sediment cannot be conveyed downward through the cover plate. When the sediment is conveyed upward, the sediment pushes the cover plate upward through the sediment through holes of the annular seat ring, enabling the sediment to be conveyed upward through the sediment through holes of the annular seat ring, realizing the one-way conveyance of sediment.

[0013] Preferably, it further includes a water pump, a first water delivery pipe, four four-way valves and a plurality of nozzles. The water pump is installed on the floating box. The upper end of the first water delivery pipe is connected to the water outlet of the water pump, and the lower end of the first water delivery pipe is connected to the water inlet channels of the four four-way valves. The four four-way valves are respectively installed at the four corners of the mud box. A plurality of nozzles are installed on the plurality of water outlet channels of the four four-way valves. The plurality of nozzles respectively face forward, backward, left, right and upward. The water pump operates to convey high-pressure water to the four four-way valves through the first water delivery pipe. By adjusting the opening and closing of the plurality of water outlet channels of the four four-way valves, the high-pressure water is sprayed out through the plurality of nozzles facing forward, backward, left or right. Under the action of the reaction force, the mud box is pushed in the reverse direction, realizing the position movement of the mud box. When the high-pressure water is sprayed out through the plurality of nozzles facing upward, the depth of the mud box inserted into the sediment is increased, expanding the dredging and sediment discharge range, and having good practicability.

[0014] Preferably, it further includes a second water delivery pipe, a left spray pipe and a right spray pipe. One end of the second water delivery pipe is connected to the water outlet of the water pump. The input ends of the left spray pipe and the right spray pipe are both connected to the output end of the second water delivery pipe. The output ends of the left spray pipe and the right spray pipe extend out of the rear end of the floating box. The output ends of the left spray pipe and the right spray pipe are oppositely arranged on the left and right sides of the floating box. The water pump operates to convey high-pressure water to the left spray pipe and the right spray pipe through the second water delivery pipe. When the left spray pipe and the right spray pipe spray water with equal flow rates, the reaction force pushes the floating box forward. When the left spray pipe and the right spray pipe spray water with different flow rates, a deflection moment is generated, causing the floating box to turn, improving the maneuverability of the floating box and expanding the dredging range.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: The external high-pressure gas system is cancelled, the air supply pressure is not affected by the water depth of the river channel, and the disturbed and dredged silt is discharged after being concentrated by the mud box cover, without spreading into the river water, which is beneficial to discharging the sediment from the river channel and has good practicability.

On the contrary, these embodiments are provided so that the disclosure of the present invention is more thorough and comprehensive.

[0029] Embodiment 1:

[0030] As Figures 1 to 4 , Figure 7 , Figure 10 and Figure 11As shown in the figure, a Yellow River dredging and sand discharging platform includes a floating box 1; it also includes a mud box 2, a blasting air pipe 3, an electromagnetic coil 1 4, an electromagnetic coil 2 5, a magnetic piston 6, an air inlet pipe 7, a sling mechanism and a sand discharging mechanism. A chamber is arranged inside the mud box 2, and a lower opening communicating with the chamber is arranged on the lower end surface of the mud box 2. The mud box 2 is suspended below the floating box 1 through the sling mechanism. The blasting air pipe 3 is vertically installed in the chamber of the mud box 2. The upper end of the blasting air pipe 3 is closed, and an air outlet is arranged at the lower end. A one-way pressure limiting valve is installed in the air outlet of the blasting air pipe 3. The electromagnetic coil 1 4 is sleeved on the upper part of the blasting air pipe 3, and the electromagnetic coil 2 5 is sleeved on the lower part of the blasting air pipe 3. The magnetic piston 6 is slidably installed inside the blasting air pipe 3. The upper end of the air inlet pipe 7 extends out of the water surface, and the lower end of the air inlet pipe 7 is connected to the inside of the blasting air pipe 3. A one-way valve is installed in the lower end of the air inlet pipe 7. The sand discharging mechanism is installed on the mud box 2 and is used to discharge the sediment in the chamber of the mud box 2; it also includes a gas tank box 8, a gas pipe 9, an air pipe 10, a mixing box 11 and a spark plug 12. The gas pipe 9 and the mixing box 11 are installed on the floating box 1. A gas tank and an air tank are arranged inside the gas tank box 8. The two ends of the gas pipe 9 are respectively connected to the gas tank and the input end of the mixing box 11. The two ends of the air pipe 10 are respectively connected to the air tank and the input end of the mixing box 11. The upper end of the air inlet pipe 7 is connected to the output end of the mixing box 11, and the spark plug 12 is installed at the lower end inside the blasting air pipe 3; it also includes a plurality of cutting knives 13, and a plurality of cutting knives 13 are installed on the outer wall of the lower end of the blasting air pipe 3; it also includes a guide rod 14 and a spring 1 15. The guide rod 14 is installed at the upper end of the blasting air pipe 3, and the guide rod 14 is slidably inserted into the cross beam at the upper part of the chamber of the mud box 2. The upper end of the spring 1 15 is connected to the cross beam, and the lower end of the spring 1 15 is connected to the blasting air pipe 3.

[0031] During operation, the floating box 1 moves to the dredging position, releases the mud box 2 to the bottom of the river through the sling mechanism, and makes the lower opening edge of the mud box 2 shovel into the sediment. The air outlet of the blasting air pipe 3 is inserted into the sediment, and multiple cutting knives 13 shovel into the sediment to cut the sediment. The electromagnetic coil 1-4 is energized to generate a magnetic force to attract the magnet piston 6 to the upper part of the blasting air pipe 3. The gas in the gas tank of the gas tank box 8 is input into the mixing box 11 through the gas pipe 9, and the air in the air tank is input into the mixing box 11 through the air pipe 10. The gas and air are mixed in the mixing box 11, and the mixed gas is input into the interior of the blasting air pipe 3 through the intake pipe 7. The electromagnetic coil 1-4 switches the energizing circuit to make the magnetic pole conversion repel the magnet piston 6, and at the same time the electromagnetic coil 2-5 is energized to attract the magnet piston 6, so that the magnet piston 6 quickly moves to the lower part of the blasting air pipe 3, so that the magnet piston 6 compresses the mixed gas inside the blasting air pipe 3. The spark plug 12 ignites to detonate the compressed mixed gas, thereby generating deflagration gas with greater pressure and impact force. The deflagration gas is discharged through the air outlet of the blasting air pipe 3 and the one-way pressure limiting valve to impact and break the sediment at the bottom of the river. The discharged deflagration gas impacts and breaks the sediment at the bottom of the river. Repeating the above actions makes the blasting air pipe 3 continuously eject air to break the sediment at the bottom of the river. The guide rod 14 and the cross beam of the mud box 2 are slidably inserted to limit and guide the blasting air pipe 3. The elastic force of the spring 1-15 pushes the blasting air pipe 3 downward, so that the lower end of the blasting air pipe 3 is always inserted into the sediment, ensuring the stable effect of the blasting air pipe 3 exhausting air to impact the sediment multiple times. The broken sediment is covered by the mud box 2 in the chamber and will not spread into the river water. The sand discharging mechanism operates to discharge the sediment in the mud box 2. Compared with the prior art, the external high-pressure gas system is cancelled, the air supply pressure is not affected by the water depth of the river, and the disturbed and dredged silt is covered and concentrated by the mud box 2 and then discharged, and will not spread into the river water, which is beneficial to discharging the sediment out of the river.

[0032] Embodiment 2:

[0033] As Figures 1 to 6As shown, on the basis of Embodiment 1, the sling mechanism includes a winch 16 and a sling 17. The winch 16 is installed on the floating box 1. The upper end of the sling 17 is wound on the winch 16, and the lower end of the sling 17 is connected to the mud box 2. It further includes a water pump 29, a first water supply pipe 30, four four-way valves 31 and multiple nozzles 32. The water pump 29 is installed on the floating box 1. The upper end of the first water supply pipe 30 is connected to the water outlet of the water pump 29, and the lower end of the first water supply pipe 30 is connected to the water inlet channels of the four four-way valves 31. The four four-way valves 31 are respectively installed at the four corners of the mud box 2. Multiple nozzles 32 are installed on the multiple water outlet channels of the four four-way valves 31, and the multiple nozzles 32 respectively face forward, backward, left, right and upward. It further includes a second water supply pipe 33, a left spray pipe 34 and a right spray pipe 35. One end of the second water supply pipe 33 is connected to the water outlet of the water pump 29. The input ends of the left spray pipe 34 and the right spray pipe 35 are both connected to the output end of the second water supply pipe 33.

[0034] When the water pump 29 operates, it conveys high-pressure water to the left spray pipe 34 and the right spray pipe 35 through the second water supply pipe 33. When the left spray pipe 34 and the right spray pipe 35 spray water with equal flow rate, the reaction force pushes the floating box 1 forward. When the left spray pipe 34 and the right spray pipe 35 spray water with different flow rates, a deflection moment is generated, causing the floating box 1 to turn, improving the maneuverability of the floating box 1 and expanding the dredging range. After the floating box 1 reaches the designated position, the winch 16 winds up the sling 17 to lift the mud box 2, and the winch 16 releases the sling 17 to lower the mud box 2, thereby adjusting the depth position of the mud box 2 and facilitating the lifting and lowering of the mud box 2. When the water pump 29 operates, it conveys high-pressure water to the four four-way valves 31 through the first water supply pipe 30, and adjusts the opening and closing of the multiple water outlet channels of the four four-way valves 31, so that the high-pressure water is sprayed out through the multiple nozzles 32 facing forward, backward, left or right, and the mud box 2 is pushed in the reverse direction under the action of the reaction force, realizing the position movement of the mud box 2. The high-pressure water is sprayed out through the multiple nozzles 32 facing upward, increasing the depth of the mud box 2 inserted into the sediment and expanding the dredging and sand discharging range.

[0035] Embodiment 3:

[0036] As Figures 1 to 4 、 Figure 6 、 Figure 8 and Figure 9As shown, on the basis of Embodiment 1, the sand discharging mechanism includes a conveying pipe 18, an upper one-way component 19, a lifting pipe 20, a lower one-way component 21, an electromagnetic coil three 22, a sealing sleeve 23, and an electromagnetic coil four 24. The conveying pipe 18 is installed on the upper end surface of the mud box 2. A mud discharging pipe is installed at the upper end of the conveying pipe 18, and the mud discharging pipe extends above the water surface. The conveying pipe 18 communicates with the chamber of the mud box 2. The upper one-way component 19 is installed at the upper end inside the conveying pipe 18. The lifting pipe 20 is slidably installed at the lower end inside the conveying pipe 18. The lower one-way component 21 is installed at the lower end of the lifting pipe 20. The electromagnetic coil three 22 is sleeved on the outer wall of the lower end of the conveying pipe 18. The sealing sleeve 23 is slidably sleeved on the upper outer wall of the conveying pipe 18. A chute is provided on the upper side wall of the conveying pipe 18. The connecting member of the lifting pipe 20 is connected to the sealing sleeve 23 through the chute. The electromagnetic coil four 24 is sleeved on the outer wall of the sealing sleeve 23. It further includes a spring two 25. The spring two 25 is sleeved outside the conveying pipe 18. The lower end of the spring two 25 is connected to the electromagnetic coil three 22, and the upper end of the spring two 25 is connected to the electromagnetic coil four 24. The upper one-way component 19 includes an annular seat ring 26, a cover plate 27, and a spring three 28. The annular seat ring 26 is installed in the conveying pipe 18. A sliding sleeve is provided in the middle of the annular seat ring 26. A plurality of sediment through holes are provided on the annular seat ring 26. The lower end surface of the cover plate 27 is concentrically provided with a sliding rod. The sliding rod of the cover plate 27 is slidably inserted into the sliding sleeve of the annular seat ring 26. The spring three 28 is sleeved on the sliding rod of the cover plate 27. The upper end of the spring three 28 is connected to the annular seat ring 26, and the lower end of the spring three 28 is connected to the lower end of the sliding rod of the cover plate 27. The elastic force of the spring three 28 pulls the cover plate 27 tightly onto the upper end surface of the annular seat ring 26. The lower one-way component 21 has the same structure as the upper one-way component 19.

[0037] When it is necessary to discharge the broken sediment in the chamber of the mud box 2, the electromagnetic coil three 22 and the electromagnetic coil four 24 are energized so that the electromagnetic coil three 22 and the electromagnetic coil four 24 attract each other. The electromagnetic coil four 24 drives the lifting pipe 20 to move downward along the conveying pipe 18, so that the lower part of the lifting pipe 20 extends into the chamber of the mud box 2. The sediment in the chamber of the mud box 2 enters the inside of the lifting pipe 20 and the conveying pipe 18 through the lower one-way component 21. The electromagnetic coil three 22 and the electromagnetic coil four 24 switch the circuit to make the electromagnetic coil three 22 and the electromagnetic coil four 24 repel each other, so that the electromagnetic coil four 24 drives the lifting pipe 20 to rise along the conveying pipe 18. The lower one-way component 21 closes and cooperates with the lifting pipe 20 to push the sediment in the conveying pipe 18 to open the upper one-way component 19 and push it into the sludge discharge pipe above the conveying pipe 18. The electromagnetic coil three 22 and the electromagnetic coil four 24 switch the circuit to make the electromagnetic coil three 22 and the electromagnetic coil four 24 attract each other. The electromagnetic coil four 24 drives the lifting pipe 20 to move downward along the conveying pipe 18. The upper one-way component 19 closes the upper end of the conveying pipe 18. Repeat the above actions to gradually lift the sediment in the chamber of the mud box 2 upward, so as to discharge the sediment above the water surface; the spring two 25 elastically supports and buffers the electromagnetic coil four 24 to prevent the electromagnetic coil four 24 and the electromagnetic coil three 22 from colliding and improve safety; during the process of discharging sediment, the elastic force of the spring three 28 pulls the cover plate 27 downward, so that the cover plate 27 closes the sediment through-hole of the annular seat ring 26, so that the sediment cannot be conveyed downward through the cover plate 27. When the sediment is conveyed upward, the sediment pushes the cover plate 27 upward through the sediment through-hole of the annular seat ring 26, so that the sediment is conveyed upward through the sediment through-hole of the annular seat ring 26, realizing the one-way conveyance of sediment.

[0038] Such as Figures 1 to 11As shown in the figure, a Yellow River dredging and sediment discharging platform of the present invention, when working, first the water pump 29 operates to convey high-pressure water through the second water delivery pipe 33 to the left spray pipe 34 and the right spray pipe 35. The reaction force pushes the floating box 1 to move to the designated dredging position. The winch 16 releases the sling 17 to lower the mud box 2 to the bottom of the river channel, and the lower opening edge of the mud box 2 shovels into the sediment. The air outlet of the blasting air pipe 3 and multiple cutting knives 13 are inserted into the sediment. Then, the gas in the gas tank in the gas tank box 8 is input into the mixing box 11 through the gas pipe 9, and the air in the air tank is input into the mixing box 11 through the air pipe 10. The gas and air are mixed in the mixing box 11, and the mixed gas is input into the interior of the blasting air pipe 3 through the air inlet pipe 7. The electromagnetic coil 1 4 is energized to generate a magnetic force to attract the magnet piston 6 to the upper part of the blasting air pipe 3. The outside air is input into the interior of the blasting air pipe 3 through the air inlet pipe 7. The electromagnetic coil 1 4 switches the energizing circuit to cause the magnetic pole to change and repel the magnet piston 6. At the same time, the electromagnetic coil 2 5 is energized to attract the magnet piston 6, so that the magnet piston 6 quickly moves to the lower part of the blasting air pipe 3, thereby compressing the air inside the blasting air pipe 3 by the magnet piston 6. The spark plug 12 ignites to detonate the compressed mixed gas, thereby generating deflagration gas with greater pressure and impact force. The deflagration gas is discharged through the air outlet of the blasting air pipe 3 to impact and break the sediment at the bottom of the river channel. Repeat the above actions to continuously eject air from the blasting air pipe 3 to break the sediment at the bottom of the river channel. Then, the broken sediment is covered by the mud box 2 in the chamber and will not spread into the river water. The electromagnetic coil 3 22 and the electromagnetic coil 4 24 are energized so that the electromagnetic coil 3 22 and the electromagnetic coil 4 24 attract each other. The electromagnetic coil 4 24 drives the lifting pipe 20 to move downward along the conveying pipe 18, so that the lower part of the lifting pipe 20 extends into the chamber of the mud box 2. The sediment in the chamber of the mud box 2 enters the interior of the lifting pipe 20 and the conveying pipe 18 through the lower one-way component 21. The electromagnetic coil 3 22 and the electromagnetic coil 4 24 switch the circuit to make the electromagnetic coil 3 22 and the electromagnetic coil 4 24 repel each other, so that the electromagnetic coil 4 24 drives the lifting pipe 20 to rise along the conveying pipe 18. The lower one-way component 21 closes to cooperate with the lifting pipe 20 to push the sediment in the conveying pipe 18 to open the upper one-way component 19 and push it into the sludge discharge pipe above the conveying pipe 18. The electromagnetic coil 3 22 and the electromagnetic coil 4 24 switch the circuit to make the electromagnetic coil 3 22 and the electromagnetic coil 4 24 attract each other. The electromagnetic coil 4 24 drives the lifting pipe 20 to move downward along the conveying pipe 18. The upper one-way component 19 closes the upper end of the conveying pipe 18. Repeat the above actions to finally gradually lift the sediment in the chamber of the mud box 2 and discharge the sediment above the water surface.
