Description

Technical Field

[0001] This invention relates to the field of dredging pump technology, and in particular to a wide-channel, high-power dredging pump for silt removal and desilting. Background Technology

[0002] A dredging pump is a special centrifugal pump designed specifically for dredging, sediment removal, and mud removal operations. It is mainly used to transport solid-liquid mixtures containing large amounts of solid particles such as mud, sand, rocks, and aquatic plants. Its core function is to extract and transport underwater sediments to designated locations using powerful suction and head. It is widely used in engineering fields such as channel excavation, port expansion, river management, and land reclamation, and is indispensable in dredging and sediment removal.

[0003] Chinese patent CN207018204U discloses a dredging pump for seabed dredging, comprising a pump body, pump cover, support column, bearing bushing, main shaft, impeller, bearing bracket, bearing end cover, bearing, and shaft sleeve. The pump body is directly fixed on the pump cover, the support column of the pump body supports the bearing, a base is directly provided at the bottom of the pump body, the pump cover is installed at the front end of the pump body, the impeller is provided on the pump cover, the impeller is installed at the front end of the main shaft, the front end of the impeller is fixed to the bearing bushing by fastening bolts, the bearing bracket is supported on the outside of the bearing, and a shaft sleeve is provided at the contact point between the pump cover and the main shaft. By changing and optimizing the shape of the flow channel and increasing the curvature of the flow channel, it is better adapted to the internal flow, reduces resistance, increases the passability of silt and sand, and improves the efficiency of dredging.

[0004] However, during the dredging process, the mud contains varying amounts of plastic bags and branches. When the dredging pump sucks in these impurities, the plastic bags are easily stuck inside the pump body, especially the impeller, which affects the rotation of the impeller. The branches are even more likely to get stuck inside the pump body, which can directly cause the impeller to stop rotating. If the pump is filtered before suction, the plastic bags and branches will also easily get stuck on the filter screen, which will clog the filter screen and require constant cleaning, which seriously affects the efficiency of dredging.

[0005] Therefore, we propose a wide-channel, high-power dredging pump for silt removal and desilting. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention proposes a wide-channel, high-power dredging pump. Through a control valve, a small motor, an electric telescopic rod, an arc plate, and prisms and triangular cones, during the dredging process, an external motor is started, which drives the transmission components to rotate, thereby driving the rotating components to rotate, thus drawing mud from the outside into the pump casing. After being accelerated by the rotation of the rotating components, it is discharged from one side of the pump casing. Since the pump casing has a flow channel width of 450mm, it can be used for media with large solid particles and adapt to the dredging requirements of high concentration and large flow rate.

[0023] During operation, when plastic bags or branches block the feed pipe, the control valve is briefly closed, and then the electric telescopic rod is activated. The telescopic nature of the electric telescopic rod causes the arc plate to move downward, causing the triangular cone to pierce the plastic bag or branch. This can hold the plastic bag in place and break the branch, preventing the plastic bag and branch from blocking the feed pipe and thus improving the feeding efficiency and quality of the feed pipe.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To address the technical challenges of reducing congestion, such as... Figures 1-6 As shown, the following preferred technical solutions are provided:

[0038] A wide-channel, high-power dredging pump includes a pump casing 1, a feeding component 2 disposed on one side of the pump casing 1, and a transmission component 3 disposed on the other side of the pump casing 1. One end of the transmission component 3 is connected to an external motor, and a rotating component 6 is disposed inside the pump casing 1. The other end of the transmission component 3 is connected to the rotating component 6.

[0039] The feeding component 2 includes a feeding pipe 23 disposed on one side of the pump casing 1, and an anti-blocking component 24 disposed inside the feeding pipe 23. The anti-blocking component 24 includes a control valve 241 and a processing component 242 disposed inside the feeding pipe 23. The feeding pipe 23 is connected to the dredging pipeline.

[0040] The processing component 242 includes a small motor 2421 mounted on the outer surface of the feed pipe 23. An electric telescopic rod 2422 is mounted at the output end of the small motor 2421. One end of the electric telescopic rod 2422 is equipped with an arc-shaped plate 2423 located inside the feed pipe 23. A prismatic rod 2424 and a triangular pyramid 2426 are mounted on one side of the arc-shaped plate 2423. One end of the prismatic rod 2424 is elastically connected to a through rod 2425. During dredging, an external motor is activated, driving the transmission component 3 to rotate, which in turn drives the rotating component 6 to rotate, thereby drawing sludge from the outside into the pump casing 1. After being accelerated by the rotation of the rotating component 6, the sludge is discharged from one side of the pump casing 1. The flow channel width of the pump casing 1 is 450mm, suitable for large-particle solids such as sand and gravel, and silt, adapting to high-concentration, high-flow-rate dredging requirements. When large impurities such as plastic bags or branches appear during the operation, they will block the feed pipe 23. At this time, the control valve 241 is closed briefly, and then the electric telescopic rod 2422 is activated. The telescopic nature of the electric telescopic rod 2422 causes the arc plate 2423 to move downward, so that the triangular cone 2426 can pierce the plastic bag or branch, which can pierce the plastic bag and break the branch, preventing the plastic bag and branch from blocking the feed pipe 23, thereby improving the feeding efficiency and quality of the feed pipe 23. When the mud movement speed in the feed pipe 23 is slow, the small motor 2421 is activated. Its output end drives the arc plate 2423 to rotate 90 degrees and brings the two sets of arc plates 2423 closer to each other, so that they form a spindle shape, which can speed up the movement speed of the mud. After rotating 90 degrees, the side of the through rod 2425 is thinner, which can cut the soil clods in the mud.

[0041] Two sets of processing components 242 are provided, and the two sets of processing components 242 are arranged opposite each other. A through rod 2425 is provided between the two sets of ribs 2424. A through hole 2427 is opened on the outer surface of the through rod 2425. A through groove is opened in the interior of the arc plate 2423. When the arc plate 2423 is moved up and down by controlling the electric telescopic rod 2422, the two sets of ribs 2424 move in opposite directions along the through rod 2425 until the two sets of arc plates 2423 abut against each other. During the movement of the two sets of arc plates 2423, the branches attached to the surface of the ribs 2424 or through rod 2425 can be cut off. At the same time, the plastic bag can be tied to the triangular cone 2426 to prevent the feed pipe 23 from being blocked due to the large volume of the plastic bag.

[0042] The control valve 241 includes a baffle 2411 disposed inside the feed pipe 23, a connecting support rod 2412 disposed on the upper end of the baffle 2411, and a rotating disk 2414 disposed on the upper end of the connecting support rod 2412. A pad 2413 is movably disposed on the outer surface of the connecting support rod 2412 and is connected to the outer surface of the feed pipe 23. Rotating the rotating disk 2414 causes the connecting support rod 2412 to rotate, which in turn drives the baffle 2411 to rotate, thereby realizing the opening and closing of the feed pipe 23. The rotation of the rotating disk 2414 can be done manually or mechanically.

[0043] A first flange 21 is provided at one end of the feed pipe 23. A locking block 22 is provided on one side of the first flange 21. A mounting base 16 is provided on one side of the pump housing 1. A second flange 17 is provided on one side of the mounting base 16. A slot 18 is provided on the outer surface of the second flange 17. The slot 18 is engaged with the locking block 22. A feed inlet 12 is provided on one side of the pump housing 1. The pump housing 1 is connected to the feed pipe 23 through the feed inlet 12. The feed pipe 23 is connected to the second flange 17 through the first flange 21, and the locking block 22 is engaged in the slot 18 to ensure the connection stability of the feed pipe 23.

[0044] A discharge pipe 11 is provided at the upper end of the pump casing 1, a first discharge valve 13 is provided on one side of the discharge pipe 11, a second discharge valve 14 is provided on the lower outer surface of the pump casing 1, and a support base 15 is provided at the lower end of the pump casing 1. The pump casing 1 can be installed on the ground through the support base 15 to ensure stability during operation. Through the rotation of the rotating component 6, external mud can be sucked into the interior of the pump casing 1 and discharged from the discharge pipe 11. Because the discharge pipe 11 and the bottom of the interior of the pump casing 1 are prone to blockage, the second discharge valve 14 and the first discharge valve 13 can be opened to clear the blockage when they are blocked.

[0045] The rotating component 6 includes a third flange 61 disposed on one side of the pump casing 1 and a back plate 62 disposed inside the pump casing 1. The back plate 62 is connected to the third flange 61 by bolts. An impeller 63 is disposed on one side of the back plate 62, and a mudguard 64 is disposed on one side of the impeller 63. A crushing wheel 631 is disposed between the impeller 63 and the mudguard 64 and is connected to the impeller 63. One end of the transmission component 3 passes through the third flange 61 and the back plate 62 and is connected to the impeller 63. As the transmission component 3 rotates, it drives the impeller 63, the crushing wheel 631 and the mudguard 64 to rotate. As the impeller 63 rotates continuously, it can suck the mud from the outside into the pump casing 1. During the suction process, the mudguard 64 can effectively prevent stones in the mud from directly hitting the impeller 63, and the crushing wheel 631 can crush the mud between the impeller 63 and the mudguard 64, which makes it easier to transport the mud.

[0046] Specifically, during the dredging process, an external motor is started, which drives the transmission component 3 to rotate, which in turn drives the rotating component 6 to rotate, thereby drawing the slurry from the outside into the pump casing 1. After being accelerated by the rotation of the rotating component 6, the slurry is discharged from one side of the pump casing 1. Since the flow channel width of the pump casing 1 is 450mm, it can handle media with large particles such as sand and gravel and silt, and can meet the dredging requirements of high concentration and large flow. During the operation, when plastic bags or branches block the feed pipe 23, the control valve 241 is briefly closed, and then the electric telescopic rod 2422 is activated. Utilizing the telescopic property of the electric telescopic rod 2422, the arc plate 2423 moves downward, causing the triangular cone 2426 to strike the plastic bag or branch. This can secure the plastic bag and break the branch, preventing the plastic bag and branch from blocking the feed pipe 23, thereby improving the feeding efficiency and quality of the feed pipe 23.

[0047] To address the technical challenges of improving overall work efficiency, such as... Figures 7-11 As shown, the following preferred technical solutions are provided:

[0048] A support component 4 is provided at the lower end of the transmission component 3. The support component 4 includes a support box 41 located at the lower end of the transmission component 3. A water pump 44 is installed inside the support box 41. The water pump 44 has three pipe interfaces, each with a water pipe. One set of the water pipes is connected to an external water source, another set is connected to the inside of the support box 41, and the third set passes through the support box 41 and connects to the pump casing 1. Valves are installed in all three sets of water pipes. The support box 41 supports the transmission component 3. When the water pump 44 is turned on, external water can be drawn into the support box 41. When the valves of the water pipes connected to the external water source are closed, and the water pump 44 is turned on again, the water pump 44 will draw water from the support box 41 into the pump casing 1.

[0049] A flushing component 5 is provided on the outer surface of the pump casing 1. The flushing component 5 includes an insertion tube 51 provided on the outer surface of the pump casing 1. One end of the insertion tube 51 is connected to the inside of the pump casing 1. There are three sets of insertion tubes 51. One end of the three sets of insertion tubes 51 is provided with a common pipe. An end pipe 52 is provided on the outer surface of the common pipe. One end of the end pipe 52 is connected to an external hose 53. One end of the external hose 53 is connected to the water pump 44. After the work is completed, or if there is a blockage inside the pump casing 1, the water inside the support box 41 is pumped by the water pump 44 into the external hose 53. After passing through the external hose 53, it enters the insertion tube 51 and is sprayed out through the nozzle of the insertion tube 51 to clean the inner wall of the pump casing 1 and the impeller 63.

[0050] The transmission component 3 includes a bearing housing 31 located on the upper end of the support housing 41, a fourth flange 32 located on one side of the bearing housing 31, and a transmission shaft 33 inserted inside the bearing housing 31. One end of the transmission shaft 33 is connected to the impeller 63, and the other end of the transmission shaft 33 is connected to an external motor. The fourth flange 32 is connected to the third flange 61. When the external motor is started, its output end rotates, which drives the transmission shaft 33 to rotate, thereby driving the impeller 63 to rotate. The bearing housing 31 serves to support and lubricate the rotation of the transmission shaft 33.

[0051] A floating box 42 is installed inside the support box 41. An air bladder 43 is installed on the inner top wall of the support box 41. The floating box 42 and the air bladder 43 are arranged in the same vertical plane. An air guide pipe 431 is installed on the outer surface of the air bladder 43, and a one-way valve is installed inside the air guide pipe 431. An air storage box 45 is installed at the upper end of the support box 41. Two sets of air storage boxes 45 are provided. The two sets of air storage boxes 45 are respectively installed on both sides of the drive shaft 33. A conduit is installed on one side of each set of air storage boxes 45. An airflow control valve 46 is installed inside the pipe. One set of the pipes has an oil storage pipe 47 threaded at one end, and a direct injection pipe 48 is installed at one end of the other set of pipes. A connecting pipe 49 is installed at one end of the direct injection pipe 48, located above the drive shaft 33. An oil outlet pipe 471 is threaded at one end of the oil storage pipe 471, and a Z-shaped pipe 472 is installed at one end of the oil outlet pipe 471. The outlet of the oil outlet pipe 471 is threaded at one end, and one end of the connecting pipe 49 is connected to the middle of the Z-shaped pipe 472. The airbag 43 is connected to the air storage tank 45 via a branch pipe, which is also equipped with a one-way valve. Water is injected into the support box 41 by the water pump 44. Since the positioning plate 411 is fixedly installed on the inner wall of the support box 41, the initial position of the floating box 42 is at the upper end of the positioning plate 411. When water is injected, the buoyancy of the water will cause the floating box 42 to move upward until it squeezes the airbag 43, allowing the gas in the airbag 43 to enter the air storage tank 45 as a backup. When the flow is obstructed, open one of the airflow control valves 46. Due to the high air pressure in the air tank 45, an airflow will be generated and blown towards the oil reservoir 47. Lubricating oil is pre-filled in the oil reservoir 47. The generated airflow will make piston motion in the oil reservoir 47, pushing the lubricating oil in the oil reservoir 47 into the oil outlet 471 and the Z-shaped pipe 472. Then open the other airflow control valve 46. Similarly, an airflow will be generated and blown towards the middle of the Z-shaped pipe 472. Then the airflow will flow to both ends, accelerating the flow of lubricating oil.

[0052] The bearing housing 31 houses a first bearing 34 and a second bearing 35, which are fitted onto the outer surface of the drive shaft 33. Multiple sets of annular tubes 36 are fitted onto the outer surfaces of the first bearing 34 and the second bearing 35, and are connected at their bottoms by connecting pipes. One set of annular tubes 36 has an upper connecting pipe 37 at its lower end, with one end of the upper connecting pipe 37 located inside the support housing 41. The two ends of a Z-shaped tube 472 are respectively opposite to the first bearing 34 and the second bearing 35. When water is injected into the support housing 41, the water slowly enters the annular tube 36, thus cooling the first bearing 34 and the second bearing 35. When the water in the support housing 41 is extracted, the water in the annular tube 36 flows out as the water level drops. Lubricating oil sprayed from both ends of the Z-shaped tube 472 is directly sprayed onto the interior of the first bearing 34 and the second bearing 35, thus providing lubrication.

[0053] A liner 19 is embedded in the inner wall of the pump casing 1. A wireless vibration sensing unit 191 is installed on one side of the liner 19. A pressure sensing unit 231 is installed on the inner wall of the feed pipe 23. A temperature monitoring unit 311 is installed on the inner wall of the bearing housing 31. The wireless vibration sensing unit 191, the pressure sensing unit 231, and the temperature monitoring unit 311 are all connected to an external mobile terminal controller. The wireless vibration sensing unit 191 monitors the vibration frequency and amplitude of the liner 19 to determine whether there is a blockage inside the pump casing 1. The pressure sensing unit 231 monitors the real-time force on the feed pipe 23 to determine whether there is a blockage inside the feed pipe 23. The temperature monitoring unit 311 monitors the internal temperature of the bearing housing 31. Temperature values ​​are used to determine whether there is any abnormality in the transmission within the bearing housing 31. When the wireless vibration sensing unit 191, pressure sensing unit 231, and temperature monitoring unit 311 detect an abnormality, the overall power is adjusted or the system is started or stopped via the mobile terminal controller. During operation, the wireless vibration sensing unit 191, pressure sensing unit 231, and temperature monitoring unit 311 monitor the overall data in real time and transmit the data to the mobile terminal controller. The operator can adjust the overall operating parameters in real time based on the transmitted data to ensure environmentally friendly operation. At the same time, when the feed pipe 23 becomes blocked, the mobile terminal controller can also be used to control the small motor 2421 and the electric telescopic rod 2422 to clear the blockage in the feed pipe 23.

[0054] Specifically, during the dredging process, the first bearing 34, the second bearing 35 and the drive shaft 33 continuously generate heat through friction. When water is injected into the support box 41, the water in the support box 41 will slowly enter the annular pipe 36, thereby cooling the first bearing 34 and the second bearing 35.

[0055] In addition, when a blockage occurs inside the pump casing 1, the water inside the support box 41 is pumped by the water pump 44 to the external hose 53, enters the insertion tube 51 through the external hose 53, and is sprayed out through the nozzle of the insertion tube 51 to clean the inner wall of the pump casing 1 and the impeller 63, which can unblock the pump casing 1 in time and improve work efficiency.

[0056] Before each operation, water needs to be injected into the support box 41. During the water injection process, the floating box 42 moves upward with the water until it squeezes the air bag 43, causing the gas in the air bag 43 to enter the air storage box 45 for backup. When the overall operation is not smooth, one set of airflow control valves 46 is opened. Due to the high air pressure in the air storage box 45, an airflow is generated and blown towards the oil storage pipe 47. Lubricating oil is loaded into the oil storage pipe 47 in advance. The generated airflow will make piston movement in the oil storage pipe 47, pushing the lubricating oil in the oil storage pipe 47 into the oil outlet pipe 471 and the Z-shaped pipe 472. Then, another set of airflow control valves 46 is opened, which similarly generates an airflow that blows towards the middle of the Z-shaped pipe 472. Subsequently, the airflow flows to both ends, accelerating the flow of lubricating oil, causing the lubricating oil to be sprayed into the first bearing 34 and the second bearing 35, improving the lubrication of the first bearing 34 and the second bearing 35, and indirectly improving the overall working efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
