Description

Technical Field

[0001] This invention relates to the field of sand mining technology, and in particular to a high-efficiency and environmentally friendly sand pumping device. Background Technology

[0002] Sand dredging is a technology that uses specialized equipment to extract sand and gravel resources from the bottom of water bodies. It is widely used in river dredging, sand mining operations, and engineering construction. The core component of a sand dredger (sand suction vessel) is the sand suction pump, which uses the pump's suction force to extract underwater sand, gravel, or sludge and transport it to a designated location via a discharge pipe. During reclamation operations, sand unloaded from sand hoppers on sand dredging vessels is typically pumped out to the reclamation area using mud pumps.

[0003] However, the following problems were found during on-site construction: 1. The sand unloading position of the sand unloading ship is inaccurate, requiring on-site command. Construction workers are unsafe to work at night or in rough seas; 2. Multiple sand ships unload sand at the same time, with a large amount of sand unloaded. A large amount of sand carries a large amount of air into the suction port and mud pump, causing blockages, pump blockages, and large cavitation margins; 3. When sand is transferred from the sand ship to the sand hopper, it will harden around the sand hopper, causing sand accumulation. It cannot be smoothly pumped into the mud pump and discharged to the filling area. The hardening of the sand not only causes insufficient sand supply, but also poses a great safety hazard to the ship. Summary of the Invention

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] like Figures 1 to 4 As shown, this embodiment proposes a high-efficiency and environmentally friendly sand pumping device, including an installation bracket 1 and a sand hopper 2 installed on a ship, and also including: a bridge support 3, a discharge pipe 4 and a support frame 5. The bridge support 3 is fixed inside the sand hopper 2 and is used to divide the falling sand. The discharge pipe 4 is fixed on the lower side of the sand hopper 2. The end of the discharge pipe 4 away from the sand hopper 2 is connected to a mud pump on the ship through a pipeline. A drive motor 6 is fixed on the support frame 5. The output shaft of the drive motor 6 is connected to a rotating shaft 601 that is rotatably connected to the support frame 5. The end of the rotating shaft 601 away from the drive motor 6 extends into the discharge pipe 4 and is connected to a spiral conveying blade 602. The rotating shaft 601 is provided with a sand equalization mechanism for uniformly discharging the sand. Furthermore, the bridge support component 3 includes a guide plate 301, a steel plate connector 302, and a connecting wire 303. The guide plate 301 is located on the upper part of the sand hopper 2, and the steel plate connector 302 is located on the lower side of the guide plate 301. The steel plate connector 302 is composed of several crisscrossing steel plates connected together. The connecting wire 303 is arranged on the crisscrossing steel plates. The top two sides of the guide plate 301 are provided with guide ramps. When the sand unloading vessel unloads sand into the sand bucket 2, the sand scatters onto the bridge support 3. The bridge support 3 divides the scattered sand to prevent it from clumping together in the sand bucket 2, which would clog the mud pump. The bridge support 3, in conjunction with the sand equalization mechanism, improves the unloading point by increasing its surface area and the area where the sand scatters, preventing sand accumulation during unloading, reducing the amount of air carried by the sand when it enters the mud pump, reducing cavitation, and avoiding blockages and pump stagnation, thereby improving sand mining efficiency. Furthermore, when the drive motor 6 is running, its rotating shaft 601 drives the spiral conveyor blade 602 to rotate inside the discharge pipe 4, allowing the spiral conveyor blade 602 to transport sand within the discharge pipe 4. This prevents sand from entering the narrow discharge pipe 4 and causing blockages, ensuring the continuity of sand discharge and improving pumping efficiency.

[0024] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the sand equalization mechanism further includes a reciprocating screw 7, a sleeve 701, a plurality of equalization plates 702, a movable rod 703, and a positioning ring 704. The positioning ring 704 is disposed on the outside of the rotating shaft 601 and is coaxial with the rotating shaft 601. The reciprocating screw 7 is disposed on the outside of the rotating shaft 601. The sleeve 701 is threadedly connected to the reciprocating screw 7. The plurality of equalization plates 702 are evenly disposed on the outside of the sleeve 701 in a circular pattern. The movable rod 703 is movably connected between the equalization plates 702 and the positioning ring 704. When the sand equalization mechanism is working, the rotating shaft 601 drives the reciprocating screw 7 to rotate, and the sleeve 701 moves axially along the reciprocating screw 7, causing the sleeve 701 to drive the equalization plate 702 to move up and down reciprocally. It should be noted that a guide rod should be set on the outside of the sleeve 701 to limit the movement direction of the sleeve 701. This is the prior art. In this application, a telescopic guide rod can be set between the top of the sleeve 701 and the bottom of the support frame 5 to guide the sleeve 701. When the height of the positioning ring 704 remains unchanged, the movable rod 703 swings freely when the equalization plate 702 moves. When the equalization plate 702 tilts up and down and swings back and forth, the sand falling on the equalization plate 702 will slide down the inclined surface of the equalization plate 702 with the constantly changing inclination angle, thereby changing the falling position of the sand. This improves the sand unloading point, increases the surface area of ​​the sand unloading point, increases the sand scattering area, prevents sand accumulation during sand unloading, and ensures the subsequent mud pumping effect and pumping efficiency.

[0025] like Figure 3As shown, in a preferred embodiment, based on the above method, a gap is further provided between two adjacent uniform material plates 702 for sand to fall; the gap facilitates the acceleration of the overall falling speed of the sand, so that some sand falls directly without being blocked by the uniform material plate 702, avoiding the uniform material plate 702 blocking the falling sand for too long, causing the sand to accumulate on the upper side of the sand hopper 2 and not fall quickly, thus affecting the overall efficiency of the sand pumping.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the sleeve 701 further includes an upper cylinder 7011 threadedly connected to the reciprocating lead screw 7 and a lower cylinder 7012 rotatably connected to the upper cylinder 7011. Each material leveling plate 702 is rotatably connected to the lower cylinder 7012 via a pin. The positioning ring 704 is fixedly connected to the rotating shaft 601. When the rotating shaft 601 rotates, it will drive the positioning ring 704 to rotate. The positioning ring 704 will then drive the uniform material plate 702 and the lower cylinder 7012 to rotate relative to the upper cylinder 7011 through the movable rod 703, changing the position of the gap between the uniform material plates 702. This will cause the position of the gap to continuously change within the sand hopper 2, preventing the falling sand from passing through the gap between the uniform material plates 702 and accumulating in one place. This will change the falling position of the sand, improve the sand unloading point, increase the surface area of ​​the sand unloading point, increase the sand scattering area, and prevent sand accumulation during sand unloading. It should be noted that as the uniform material plate 702 and the movable rod 703 rotate inside the sand hopper 2, the uniform material plate 702 and the movable rod 703 can stir and crush the sand falling inside the sand hopper 2, so that the sand is evenly distributed inside the sand hopper 2, while avoiding sand caking, and ensuring the subsequent sand pumping efficiency and sand pumping effect of the mud pump.

[0027] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, a connecting plate 8 is further fixed on the positioning ring 704. The end of the connecting plate 8 away from the positioning ring 704 is rotatably connected to the actuating plate 801 through a pin. A connecting rod 802 is movably connected between the top of the actuating plate 801 and the middle of the movable rod 703. As the movable rod 703 swings up and down with the uniform plate 702, the movable rod 703 applies force to the actuating plate 801, causing the actuating plate 801 to rotate around the pin connected to the connecting plate 8. This causes the actuating plate 801 to agitate the sand on the lower side of the sand hopper 2, pushing the sand on the lower side of the sand hopper 2 towards the feed pipe 4, allowing the sand to quickly enter the feed pipe 4, ensuring the feed rate and continuity of the sand hopper 2, thereby improving the sand pumping efficiency.

[0028] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the sidewalls of the uniform plate 702, the movable rod 703, the connecting plate 8, the actuating plate 801, and the connecting rod 802 are all configured as guide arc surfaces, so that when they rotate in the sand hopper 2, their own rotational resistance is reduced, thereby reducing the operating load of the drive motor 6.

[0029] like Figure 3 and Figure 6 As shown, in a preferred embodiment, based on the above method, the upper sleeve 9 is fixedly provided at the top of the upper cylinder 7011, and the lower sleeve 901 is fixedly provided at the bottom of the lower cylinder 7012. The inner sidewalls of the upper sleeve 9 and the lower sleeve 901 are movable against the outer sidewall of the reciprocating screw 7. The upper sleeve 9 and the lower sleeve 901 are sleeved on the outside of the reciprocating screw 7, so that they are always sleeved on the outside of the reciprocating screw 7 when the sleeve 701 moves up and down, thus protecting the reciprocating screw 7 and preventing sand from entering the track groove of the reciprocating screw 7 and affecting the transmission performance of the reciprocating screw 7.

[0030] like Figure 1 and Figure 7 As shown, in a preferred embodiment, based on the above method, a water guide pipe 10 is fixedly provided on the mounting bracket 1, a connecting water pipe 1001 is rotatably connected to the top of the water guide pipe 10, a water cannon head 1002 is rotatably connected to the connecting water pipe 1001, and a handle 1003 is provided on the water cannon head 1002. To prevent sand from hardening and accumulating, and to reduce the amount of air carried by the sand, a high-pressure water jetting device is designed on the mounting bracket 1 according to the actual situation of the ship. When the sand ship unloads sand, the water cannon head 1002 sprays water to flush the sand hardened on the inner wall of the sand bucket 2, preventing sand accumulation. At the same time, it reduces dust from the sand floating in the air, avoiding large-scale air pollution. The water also disperses a large amount of air carried in the sand. The height of the water outlet can be adjusted up and down, and the angle of the water outlet can be controlled by rotating the handle 1003. This ensures that the water cannon head 1002 flushes every part of the inner wall of the sand bucket 2 without leaving any dead corners, reducing the cavitation of the mud pump, avoiding the occurrence of blockage and pump stagnation, and thus improving the efficiency of sand mining operations.

[0031] like Figure 1 and Figure 7 As shown, in a preferred embodiment, based on the above method, the mounting bracket 1 is further provided with a mounting rod 11. The end of the mounting rod 11 away from the mounting bracket 1 is connected to a camera 111. The camera 111 is provided with a wireless communication module. The camera 111 communicates with the monitor in the bridge of the ship through a wireless network. The wireless network adopts an encrypted data transmission channel based on the IEEE 802.11 protocol. Camera 111 monitors the sand unloading process on-site and uploads the captured images to a monitor on the ship's bridge, avoiding the need for on-site command during stormy weather or nighttime operations, thus reducing risks and increasing operational safety. It ensures accurate sand unloading position, controls unloading speed, reduces sand accumulation on the bucket wall, prevents excessive sand overflow from the sand bucket 2, and increases construction efficiency. At the same time, it allows staff to monitor from the bridge, reducing on-site workload and saving labor costs.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
