Description

Technical Field

[0001] The invention relates to the technical field of sand filling devices, in particular to an onshore high-efficiency combined sand filling device. Background Art

[0002] Across various construction projects, such as coastal protection, dam construction, and tidal flat reclamation, sand is in high demand, making efficient sand filling a critical component. Traditional combined sand filling devices are primarily used in complex offshore or onshore environments. Their development aims to meet the demands for rapid, high-volume sand filling under diverse operating conditions. As the scale of these projects continues to expand, the demands for sand filling efficiency and cost control become increasingly stringent, and the drawbacks of existing technologies are becoming increasingly apparent.

[0003] Existing combined sand filling devices often rely on the coordinated operation of multiple vessels during offshore operations. A pump extracts sand from the seabed and transports it via pipelines to sandbags for filling. Onshore operations often utilize large-scale machinery, such as loaders and conveyor belts, to transport the sand to a designated location, where it is then filled manually or semi-automatically. Structurally, these devices feature a pump as the core component, providing the power to extract and transport the sand. The vessel or large machinery moves and loads the sand, while components such as conveyor belts transport the material.

[0004] In actual application scenarios, such as in the construction of large-scale coastal protection projects, traditional sand filling devices have exposed many problems. Taking offshore operations as an example, the combination of multiple hulls and pump bodies requires a large amount of fuel to drive the movement of the hulls and the operation of the pump bodies. Due to the large number of hulls and the high power of the pump bodies, energy consumption increases exponentially. The reason is that under this operating mode, the coordination efficiency between equipment is low, and there is energy waste in every link. When the pump body extracts sea sand, it does not operate continuously and efficiently, and there is invalid energy consumption such as idling; in the process of moving the hull, in order to maintain a stable position, the power needs to be continuously adjusted, which also consumes a lot of extra energy. This not only leads to a significant increase in the cost of sand filling, but also causes greater pollution to the environment, and it is difficult to meet the requirements of modern engineering construction for efficiency and environmental protection. Therefore, the present invention provides an onshore high-efficiency combined sand filling device to solve the shortcomings of the existing technology. Summary of the Invention

The outside of the hanging rope is slidably connected to the outside of the U-shaped frame, and one end of the hanging rope is sleeved on the outside of the arc-shaped hanging rod.

[0009] Two door locking mechanisms are arranged on the top of the base for use with the door closing mechanism. The door locking mechanism includes a trigger assembly and a blocking assembly. The trigger assembly includes a support seat. The bottom of the support seat is fixedly connected to the top of the base. The top of the support seat is fixedly connected to an L-shaped seat. The outer side of the L-shaped seat is fixedly connected to a spring telescopic rod 1. One end of the spring telescopic rod 1 is fixedly connected to a slider. The bottom of the slider is slidably connected to the outer side of the L-shaped seat. The top of the slider is fixedly connected to an L-shaped block. The blocking assembly includes a mounting seat. The bottom of the mounting seat is fixedly connected to The top of the base is connected to the inside of the mounting seat, and a spring telescopic rod 2 is fixedly connected to the top of the spring telescopic rod 2. A stopper is fixedly connected to the top of the stopper, and a slot is provided on the top of the stopper. The outside of the L-shaped block is engaged with the inner side of the slot. Both sides of the outside of the spring telescopic rod 2 are fixedly connected to strip plates, and the outer side of the stopper is slidably connected to the outer side of the strip plate. The adjacent sides of the two strip plates are fixedly connected to a limiting block, and both sides of the outside of the stopper are provided with a sliding groove, and the outer side of the limit block is slidably connected to the inner side of the sliding groove, and the outer side of the stopper is in contact with the outer side of the sealing plate.

[0010] A guiding mechanism is arranged on the outside of the basic frame and is used to guide mud and sand into the entrance of the basic frame. The guiding mechanism includes two side plates and a guiding channel. The side plates are rotatably connected to the outside of the basic frame. A spring buffer rod is hinged between the side plates and the basic frame. The guiding channel is located outside the basic frame, and a footrest is fixedly connected to the bottom of the guiding channel.

[0013] The present invention provides an onshore high-efficiency combined sand filling device. It has the following beneficial effects:

[0014] 1. The present invention utilizes the natural impact force of the tide to fill sand. Through the coordinated cooperation of various components, it fully guides the energy of the tide without consuming a large amount of additional energy.

The stable connection of each component allows the device to work reliably in complex environments, ensuring the smooth progress of sand filling operations.

[0016] 3. The present invention cleverly guides the tide through the guide channel and the side plate, so that it accurately impacts the inlet of the device. In conjunction with the trigger plate, rotating sleeve and other structures, the sealing plate is quickly closed, and the locking mechanism is limited in time to prevent the tide from rebounding, thereby efficiently completing sand collection. The efficient coordination between the structures in the entire process reduces many complex intermediate steps in the traditional method, greatly improving the sand filling efficiency, and can collect more sand in a short time.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see the attached Figure 1 -Attached Figure 8 An embodiment of the present invention provides an onshore high-efficiency combined sand filling device, comprising: a basic frame 1, which serves as the foundation of the entire structure. Four ground nails 2 are fixedly connected to the bottom of the basic frame 1. During the device preparation stage, the ground nails 2 need to be inserted into the ground for anchoring. Each ground nail 2 needs to be deeply embedded in the ground to ensure that the position of the basic frame 1 is stable. Its bearing capacity needs to meet the weight and force requirements of subsequent assembly and operation, providing a stable support foundation for the entire device. Four hooks 3 are fixedly connected to the outside of the basic frame 1. The design of the hooks 3 ensures close fit with subsequent components.

[0028] The base 13 is detachably connected to the inner side of the basic frame 1 .

[0029] The door closing mechanism is located outside the base frame 1 and is used to seal the entrance of the base frame 1. It includes a rotating sleeve 6, which is rotatably connected to the outside of the base frame 1. In its initial state, the rotating sleeve 6 remains stable. A sealing plate 7, a trigger plate 8, and an arc-shaped hanging rod 9 are fixedly connected to its outside. A U-shaped frame 12 is fixedly connected to the top of the base frame 1. During the installation phase, one end of a hanging rope 11 must be passed over the top of the U-shaped frame 12 and accurately hooked onto the outside of the arc-shaped hanging rod 9. The position and structural design of the U-shaped frame 12 ensure that the hanging rope 11 can slide smoothly outside it. A traction seat 10 is fixedly connected to the outside of the sealing plate 7, and the hanging rope 11 is fixedly connected to the outside of the traction seat 10. When the tide arrives, the tide impacts the trigger plate 8, which is fixedly connected to the rotating sleeve 6, causing the rotating sleeve 6 and the arc-shaped hanging rod 9 to flip. During this process, one end of the hanging rope 11 will fall off the outside of the arc-shaped hanging rod 9. Since the sealing plate 7 is also fixedly connected to the rotating sleeve 6, under the influence of gravity and the force of the trigger plate 8 being impacted by the tide, the sealing plate 7 will quickly rotate toward the outside of the basic frame 1 until it fits tightly with the outside of the basic frame 1, thereby achieving the closure of the entrance of the basic frame 1.

[0030] The door locking mechanism includes two door locking mechanisms arranged on the top of the base 13 for use with the door closing mechanism. The door locking mechanism includes a trigger assembly and a blocking assembly. The trigger assembly includes a support seat 14. The bottom of the support seat 14 is fixedly connected to the top of the base 13. The top of the support seat 14 is fixedly connected to an L-shaped seat 15. The outer side of the L-shaped seat 15 is fixedly connected to a spring telescopic rod 16. One end of the spring telescopic rod 16 is fixedly connected to a slider 17. The bottom of the slider 17 is slidably connected to the outer side of the L-shaped seat 15. The top of the slider 17 is fixedly connected to an L-shaped block 18. The blocking assembly includes a mounting seat 19. The bottom of the mounting seat 19 is fixed. Connected to the top of the base 13, the interior of the mounting seat 19 is fixedly connected to a spring telescopic rod 20. During the closing process of the sealing plate 7, its outer side will hit the two L-shaped blocks 18. The L-shaped blocks 18 are slidably connected to the L-shaped seat 15 through the slider 17. When the sealing plate 7 hits the L-shaped blocks 18, the L-shaped blocks 18 overcome the elastic force of the spring telescopic rod 16 and move away from the slot 25. At this time, the spring telescopic rod 20 inside the mounting seat 19 is restricted by the disengagement of the L-shaped blocks 18, and its elastic force will quickly pop out the block 23. The top of the stopper 23 is provided with a slot 25. Two strip plates 21 are fixed to the outside of the spring telescopic rod 20. The outer side of the stopper 23 is slidably connected to the outer side of the strip plates 21. The adjacent sides of the two strip plates 21 are fixedly connected to the limit block 22. Slide grooves 24 are provided on both sides of the outer side of the stopper 23. The outer side of the limit block 22 is slidably connected to the inner side of the slide groove 24. These structures ensure the stability and accuracy of the ejection of the stopper 23. After the stopper 23 is ejected, its outer side contacts the outer side of the sealing plate 7, limiting the sealing plate 7 and preventing the rebound of the tide entering the sand bag 4, thereby ensuring the collection of sand in the sand bag 4.

[0031] The guiding mechanism is arranged on the outside of the base frame 1 and is used to guide the mud and sand into the entrance of the base frame 1. The guiding mechanism includes two side plates 26 and a guiding channel 28. During the preparation stage of the device, the guiding channel 28 is placed between the base frame 1 and the sea water. The footrest 29 at the bottom of the guiding channel 28 supports and stabilizes the guiding channel 28. The two side plates 26 are rotatably connected to the outside of the base frame 1, and the side plates 26 and the base frame 1 are hinged by spring buffer rods 27. When the tide comes, the tide will first be guided by the guiding channel 28 and the two side plates 26. The shape and position design of the guiding channel 28 can effectively change the direction of the tide, so that it flows directly towards the entrance of the base frame 1. Under the action of the spring buffer rods 27, the side plates 26 can adaptively adjust the angle according to the impact force of the tide, further ensuring that the tide can accurately impact the entrance area of the base frame 1.

[0032] The outside of the basic frame 1 is provided with a sand bag 4, and four hanging rings 5 are fixedly connected to the inside of the sand bag 4. During the preparation stage of the device, the hanging rings 5 on the sand bag 4 are respectively put on the four hooks 3 on the outside of the basic frame 1 to complete the assembly of the sand bag 4. The hooks 3 and the hanging rings 5 fit tightly together to prevent the sand bag 4 from falling off during subsequent work. The inside of the basic frame 1 is provided with a metal mesh 30, and the bottom of the metal mesh 30 is fixedly connected to a plurality of support rods 31. The bottom of the support rods 31 is inserted deep into the ground. A pit of a certain depth needs to be dug in advance at the bottom of the metal mesh 30. The sand carried by the tide accumulates inside the basic frame 1, while the water flows through the metal mesh 30 into the pit on the ground and is discharged. In this way, a bag of sand is collected.

[0033] Specifically, first, ground spikes 2 are driven into the ground to anchor the device. These spikes penetrate deep into the ground, providing stable support for the base frame 1 through their tight engagement with the ground. This stabilizes the base frame 1 and ensures that the entire device will not shake or shift during subsequent operation, laying the foundation for the proper functioning of other structural components. Next, a guide channel 28 is placed between the base frame 1 and the seawater. Its shape and position are specially designed to effectively redirect the tidal flow, directing it to the entrance of the base frame 1. This ensures that the tidal water impacts the key areas of the device more accurately and concentratedly, improving the efficiency of tidal energy utilization. Next, the loop 5 on the sandbag 4 is placed over the hook 3. The tight fit between the loop 5 and the hook 3 securely secures the sandbag 4 to the exterior of the base frame 1. The sandbag 4 stably collects the injected sand during operation, preventing it from falling or shifting, ensuring smooth sand collection. One end of the hanging rope 11 is then passed over the U-shaped frame 12 and hooked onto the exterior of the curved hanging rod 9. At this point, the hanging rope 11 is in a taut state, connecting the sealing plate 7 and the curved hanging rod 9. This keeps the sealing plate 7 initially open, leaving a path for the tide to enter. When preparations are complete and the tide arrives, it is guided by the guide channel 28 and the two side panels 26. Spring-loaded buffer rods 27 are hinged between the side panels 26 and the base frame 1. Under the impact of the tide, the side panels 26 can flexibly rotate within a certain range, further adjusting the flow of the tide and directing it directly toward the entrance of the base frame 1. The tide impacts the trigger plate 8, which is fixedly connected to the rotating sleeve 6, causing the trigger plate 8 to rotate the rotating sleeve 6 and the curved hanging rod 9. Because one end of the hanging rope 11 is attached to the curved hanging rod 9, as the curved hanging rod 9 rotates, the other end of the hanging rope 11 will fall off the outside of the curved hanging rod 9. As a result, the sealing plate 7, which was originally held by the hanging rope 11, loses its tension. Under the influence of gravity and the force of the tidal impact on the trigger plate 8, the sealing plate 7 will quickly mate with the outer side of the base frame 1 to close, promptly sealing the entrance of the base frame 1 and preventing the tidal backflow. As the sealing plate 7 closes, the outer side of the sealing plate 7 will hit the two L-shaped blocks 18. The L-shaped blocks 18 are connected to the L-shaped seat 15 by the spring telescopic rod 16. After being hit, the L-shaped blocks 18 overcome the elastic force of the spring telescopic rod 16 and move out of the slot 25. Then, the spring telescopic rod 20, which was originally in a compressed state, its elastic force will quickly eject the block 23. After the block 23 is ejected, its outer side mates with the outer side of the sealing plate 7, limiting the sealing plate 7 and preventing the tidal water from entering the sand bag 4 from rebounding. This ensures the collection effect of the sand in the sand bag 4 and prevents the sand from being dispersed or lost by the tide. A pit of a certain depth is dug in the ground at the bottom of the metal mesh 30. The metal mesh 30 has certain pores, which can block the passage of sand and allow water to pass through.When the tide carries sand into the basic frame 1, the water will flow into the pit on the ground through the metal mesh 30 and be discharged, while the sand will remain in the sand bag 4, so that a bag of sand can be collected. Compared with the traditional method of coordinating multiple hulls and pump bodies, the overall structure of this device has better synergy, reduces the intermediate steps, and directly connects the tide with the sand filling step. The traditional method requires coordination between multiple hulls and pump bodies, which is complicated to operate and inefficient. However, this device uses the natural impact force of the tide to simplify the operation process, making it more efficient and convenient. Multiple devices can be built in front of the tide, and multiple devices can work at the same time, which can make full use of the energy of the tide, reduce energy consumption, reduce the cost of sand filling, and improve the economic and environmental benefits of sand filling.

[0034] Working principle: First, insert the ground nails 2 into the ground for anchoring, so that the position of the base frame 1 is stable, and the guide channel 28 is placed between the base frame 1 and the sea water. The hanging ring 5 on the sand bag 4 is put on the hook 3 to complete the assembly of the sand bag 4, and then one end of the hanging rope 11 is passed over the top of the U-shaped frame 12 and hung on the outside of the arc-shaped hanging rod 9. At this time, the preparations are completed. When the tide comes, it will be guided by the guide channel 28 and the two side plates 26, and then directly flow to the entrance of the base frame 1, and will impact the trigger plate 8, so that the trigger plate 8 drives the rotating sleeve 6 and the arc-shaped hanging rod 9 to flip, so that one end of the hanging rope 11 will fall off from the outside of the arc-shaped hanging rod 9. Under the influence of gravity and the force of the trigger plate 8 being impacted by the tide, the seal The mouth plate 7 will quickly fit with the outer side of the basic frame 1 to achieve closure, and at this time the outer side of the sealing plate 7 will hit the two L-shaped blocks 18, causing it to move away from the slot 25, and then the elastic force of the spring telescopic rod 20 will quickly pop out the block 23, limiting the sealing plate 7 to prevent the tide entering the sand bag 4 from rebounding. A pit of a certain depth is dug in the ground at the bottom of the metal mesh 30 to drain the water in the sand bag 4, so that a bag of sand can be collected. Compared with the traditional method of cooperating with multiple hulls and pump bodies, the overall structure has better synergy, reduces intermediate steps, and directly connects the tide with the sand filling step, which is more efficient and convenient. Multiple devices can be built before the tide, which can make full use of the energy of the tide, reduce energy consumption and reduce the cost of sand filling.
