Description

Technical Field

[0001] The invention relates to the technical field of underwater riprap, in particular to an underwater riprap device with a self-positioning function. Background Art

[0002] With the increasing number of underwater projects such as marine resource development, port construction, channel regulation, and bridge foundation construction, underwater riprap operations, as a common means of foundation treatment and protection, are becoming more and more widely used.

[0003] Traditional underwater riprap devices use cranes and guide pipes to rip rocks, but lack the ability to adapt to water flow. They usually rip rocks at a fixed angle, which makes it difficult to cope with complex and changeable water flow environments. This requires operators to rely on experience to perform riprap operations, but manual judgment is difficult to accurately match the actual water flow conditions, so that some of the thrown stones cannot fall to the predetermined position, resulting in low operating efficiency, difficulty in ensuring quality, and even waste of stones. The direction and size of the water flow are the key factors affecting the effect of underwater riprap operations. If the riprap angle is not adjusted in time according to the water flow conditions, when the water flow is large, the stones may be washed away by the water flow and cannot fall accurately at the predetermined position, resulting in uneven riprap, which in turn affects the stability and protection effect of the foundation. Summary of the invention

[0004] The purpose of the present invention is to provide an underwater riprap device with a self-positioning function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The invention discloses an underwater riprap device with a self-positioning function, comprising a discharging mechanism, a No. 1 mounting frame, a feeding pipe, a self-positioning mechanism, a guide plate and a water flow driving mechanism. The discharging mechanism is fixedly connected to the No. 1 mounting frame, the self-positioning mechanism is rotatably connected to the No. 1 mounting frame, the guide plate is fixedly connected to the self-positioning mechanism, the water flow driving mechanism is fixedly connected to the guide plate, the feeding pipe is fixedly connected to the self-positioning mechanism, and the water flow driving mechanism is transmission-connected to the self-positioning mechanism.

[0007] The self-positioning mechanism is rotationally connected to the first mounting frame, and the blanking pipe is fixedly connected to the self-positioning mechanism, enabling the blanking pipe to rotate for horizontal and vertical angle adjustment, and further making the blanking pipe face the direction opposite to the water flow. The connection part between the self-positioning mechanism and the guide vane can rotate on the first mounting frame, allowing the guide vane to rotate with the water flow, and further making the guide vane rotate horizontally with the water flow direction. By fixedly connecting the guide vane and the self-positioning mechanism, the rotation of the guide vane can drive the self-positioning mechanism to rotate, thereby converting the power of the guide vane rotation into the power for adjusting the rotation of the blanking pipe. The water flow driving mechanism and the self-positioning mechanism are connected by keyway transmission, enabling the power of the water flow to be converted into the power for driving the internal transmission structure of the self-positioning mechanism to move, so that the underwater stone throwing device can automatically adjust the stone throwing angle according to the direction and magnitude of the water flow, making the stones be thrown in the direction opposite to the water flow. The stones generate a force in the direction opposite to the water flow, offsetting part of the water flow force and preventing the stones from being washed away. The unoffset force makes the stones move in the water flow direction, and further makes the stones fall to the designated position, realizing the self-positioning function of stone throwing. The stored stones fall into the blanking pipe through the discharging mechanism, thus performing underwater stone throwing.

Through the connecting block, the rotating shaft and the guide vane are indirectly fixedly connected. When the guide vane rotates with the water flow to be horizontal with the water flow direction, the rotating shaft rotates synchronously with the guide vane. By fixing the first angle adjustment unit to the rotating shaft, the first angle adjustment unit can adjust the angle according to the rotation of the rotating shaft. Through the transmission connection between the water flow driving mechanism and the transmission unit, and the fixed connection between the rotating shaft and the transmission unit, the power of the water flow driving mechanism and the power of the rotating shaft rotation can be converted into the power for the second angle adjustment unit to work.

[0016] Furthermore, the water flow driving mechanism includes a third gear, a rack, a slider, a second connecting rod, a counterweight and a spring.

The third gear and the fifth transmission shaft are connected by a keyway transmission, so that the third gear drives the fifth transmission shaft to rotate. When the water flow decreases, the spring resets the rack.

[0018] Furthermore, the discharging mechanism includes a bearing box, a baffle and an opening and closing unit. The bearing box is fixedly connected to the first mounting frame. The bearing box is provided with a discharging port. The baffle abuts against the discharging port. The baffle is fixedly connected to the opening and closing unit.

[0022] Furthermore, the upper part of the material discharge pipe is conical, and the lower part of the material discharge pipe is cylindrical.

[0023] By setting the upper part of the material discharge pipe as conical, the material discharge pipe can still catch the stones falling from the discharge port after the angle adjustment. By setting the lower part of the material discharge pipe as cylindrical, it provides a guiding function for the stones, enabling them to fall along the specified direction.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. When the water flow is large, the guide plate rotates in real time according to the direction of the water flow, driving the rotating shaft to rotate. The second bevel gear rotates with the rotating shaft, driving the first bevel gear to rotate. The first drive shaft rotates synchronously, thereby driving the material discharge pipe to rotate. At the same time, the internal gear ring and the second gear rotate respectively according to the direction and magnitude of the water flow, driving the fourth drive shaft to rotate, driving the sixth bevel gear to rotate. The fifth bevel gear rotates with the sixth bevel gear, driving the third drive shaft to rotate, further driving the fourth bevel gear to rotate, driving the third bevel gear to rotate, driving the worm to rotate, driving the worm gear to rotate, driving the second drive shaft to rotate coaxially, driving the bracket to rotate along the axis of the second drive shaft, and further driving the material discharge pipe to rotate, making the material discharge pipe face the direction opposite to the water flow, causing the stones to be thrown in the direction opposite to the water flow. The stones generate a force in the direction opposite to the water flow, offsetting part of the force of the water flow, preventing the stones from being washed away. The unoffset force makes the stones move in the direction of the water flow and fall back to the predetermined position, thus realizing the self-positioning function of the stone throwing.

[0026] 2. By controlling the opening and closing of the baffle through the motor, the switch of the discharge port of the bearing box is further controlled, thereby controlling the quantity of the thrown stones and avoiding waste of stones caused by excessive throwing.

Detailed implementation manners

[0038] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment: As Figure 1 and Figure 2 shown, the present invention provides a technical solution for an underwater stone throwing device with a self-positioning function. An underwater stone throwing device includes a discharging mechanism 1, a first mounting frame 2, a feeding pipe 3, a self-positioning mechanism 4, a flow guiding plate 5, and a water flow driving mechanism 6. The discharging mechanism 1 is fixedly connected to the first mounting frame 2. The self-positioning mechanism 4 is rotatably connected to the first mounting frame 2. The flow guiding plate 5 is fixedly connected to the self-positioning mechanism 4. The water flow driving mechanism 6 is fixedly connected to the flow guiding plate 5. The feeding pipe 3 is fixedly connected to the self-positioning mechanism 4. The water flow driving mechanism 6 is in transmission connection with the self-positioning mechanism 4.

[0040] By rotatably connecting the self-positioning mechanism 4 to the first mounting frame 2 and fixedly connecting the feeding pipe 3 to the self-positioning mechanism 4, the feeding pipe 3 can rotate to adjust the horizontal and vertical angles, so that the feeding pipe 3 faces the direction opposite to the water flow. The connecting part between the self-positioning mechanism 4 and the flow guiding plate 5 can rotate on the first mounting frame 2, enabling the flow guiding plate 5 to rotate with the water flow, and then the flow guiding plate 5 rotates to be horizontal with the water flow direction. By fixedly connecting the flow guiding plate 5 to the self-positioning mechanism 4, the rotation of the flow guiding plate 5 can drive the self-positioning mechanism 4 to rotate, so that the power of the rotation of the flow guiding plate 5 is converted into the power for adjusting the rotation of the feeding pipe 3. The water flow driving mechanism 6 is in transmission connection with the self-positioning mechanism 4 through a keyway, so that the power of the water flow can be converted into the power for driving the internal transmission structure of the self-positioning mechanism 4 to move, enabling the underwater stone throwing device to automatically adjust the stone throwing angle according to the direction and magnitude of the water flow, so that the stones are thrown in the direction opposite to the water flow. The stones generate a force in the direction opposite to the water flow, offsetting part of the water flow force and preventing the stones from being washed away. The un-offset force causes the stones to move in the water flow direction, and then the stones fall to the designated position, realizing the self-positioning function of stone throwing. Through the discharging mechanism 1, the stored stones fall into the feeding pipe 3, thereby performing underwater stone throwing.

[0041] As Figure 2 and Figure 3 shown, the self-positioning mechanism 4 includes a first angle adjustment unit 41, a second angle adjustment unit 42, a transmission unit 43, a rotating shaft 44, and a connecting block 45. The first angle adjustment unit 41 is rotatably connected to the second angle adjustment unit 42. The first angle adjustment unit 41 is fixedly connected to the feeding pipe 3. The transmission unit 43 is in transmission connection with the second angle adjustment unit 42. The rotating shaft 44 is fixedly connected to the transmission unit 43.

Through the connecting block 45, the rotating shaft 44 is indirectly fixedly connected to the guide vane 5. When the guide vane 5 rotates with the water flow to be horizontal with the water flow direction, the rotating shaft 44 rotates synchronously with the guide vane 5. The first angle adjustment unit 41 is fixed to the rotating shaft 44, enabling the first angle adjustment unit 41 to adjust the angle according to the rotation of the rotating shaft 44. The water flow driving mechanism 6 is drivingly connected to the transmission unit 43, and the rotating shaft 44 is fixedly connected to the transmission unit 43, enabling the power of the water flow driving mechanism 6 and the power of the rotation of the rotating shaft 44 to be converted into the power for the operation of the second angle adjustment unit 42.

[0044] Since the second bevel gear 414 is fixedly connected to the rotating shaft 44, the second bevel gear 414 rotates with the rotating shaft 44. Since the second bevel gear 414 meshes with the first bevel gear 413, the second bevel gear 414 drives the first bevel gear 413 to rotate. Since the first transmission shaft 412 is fixedly connected to the first bevel gear 413, the first transmission shaft 412 rotates synchronously. Since the second mounting bracket 411 is fixedly connected to the first transmission shaft 412, the entire second mounting bracket 411 rotates along the axis of the first transmission shaft 412, thereby driving the blanking pipe 3 fixed to the second angle adjustment unit 42 to rotate, so as to adjust the angle of the blanking pipe 3.

Through the rotation connection between the second transmission shaft 422 and the second mounting bracket 411, the second mounting bracket 411 supports both ends of the second transmission shaft 422. Through the fixation of the bracket 421 and the second transmission shaft 422, the second transmission shaft 422 drives the bracket 421 to rotate along the axis of the second transmission shaft 422, thereby driving the blanking pipe 3 to rotate.

[0047] As Figure 5 and Figure 6 shown, the transmission unit 43 includes a fourth transmission shaft 431, a connecting plate 432, a first connecting rod 433, a first gear 434, a second gear 435, a fifth transmission shaft 436 and an internal gear ring 437.

The baffle 12 is fixedly connected to the opening and closing unit 13.

[0052] Store the stone materials through the loading box 11, fix it through the loading box 11 and the first mounting frame 2, so that the stored stone materials do not affect the adjustment of the blanking pipe 3, and control the opening and closing of the baffle 12 through the opening and closing unit 13, thereby controlling the opening and closing of the discharge port 111 of the loading box 11.

[0053] As Figure 9 and Figure 10 As shown in the figure, the opening and closing unit 13 includes fixing blocks 131, a sixth transmission shaft 132, a chain 133, a support plate 134 and a motor 135. There are two fixing blocks 131, and the two fixing blocks 131 are fixedly connected to the loading box 11. There are two sixth transmission shafts 132. One sixth transmission shaft 132 is rotatably connected to the two fixing blocks 131. One end of the other sixth transmission shaft 132 is rotatably connected to the support plate 134, and the other end of the other sixth transmission shaft 132 is fixedly connected to the output end of the motor 135. The motor 135 is fixedly connected to the loading box 11. The chain 133 is sleeved outside the two sixth transmission shafts 132, and the chain 133 is in transmission connection with the two sixth transmission shafts 132.

[0054] Support both ends of one sixth transmission shaft 132 through the fixing block 131 fixed on the loading box 11. Through the rotation connection between the sixth transmission shaft 132 and the two fixing blocks 131, the sixth transmission shaft 132 can rotate. Fix the output end of the motor 135 to the other sixth transmission shaft 132, and support the other sixth transmission shaft 132 through the cooperation of the support plate 134, so that the motor 135 drives the sixth transmission shaft 132 to rotate. Through the chain 133 sleeved outside the two sixth transmission shafts 132, the chain 133 is in transmission connection with the two sixth transmission shafts 132 through sprockets, so that one sixth transmission shaft 132 drives the other sixth transmission shaft 132 to rotate, thereby driving the baffle 12 to rotate, thereby opening and closing the loading box 11, and further controlling the quantity of blanking.

[0055] As shown in the figure, the upper part of the blanking pipe 3 is conical, and the lower part of the blanking pipe 3 is cylindrical.

[0056] By setting the upper part of the blanking pipe 3 to be conical, after the blanking pipe 3 is adjusted in angle, it can still catch the stone materials falling from the discharge port 111. By setting the lower part of the blanking pipe 3 to be cylindrical, it provides a guiding function for the stone materials, so that they fall along the specified direction.

[0057] Working principle: The deflector 5 rotates with the water flow until it is horizontal with the water flow direction. It is indirectly fixed through the deflector 5 and the rotating shaft 44, so that the deflector 5 drives the rotating shaft 44 to rotate. The second bevel gear 414 rotates with the rotating shaft 44, so that the second bevel gear 414 drives the first bevel gear 413 to rotate. The first transmission shaft 412 rotates synchronously, so that the entire second mounting bracket 411 rotates along the axis of the first transmission shaft 412, thereby driving the blanking pipe 3 to rotate, and then adjusting the angle of the blanking pipe 3. At the same time, the internal gear ring 437 rotates coaxially with the rotating shaft 44, so that the first gear 434 rotates with the internal gear ring 437 and the second gear 435, and then the connecting plate 432 drives the fourth transmission shaft 431 to rotate, thereby driving the sixth bevel gear 429 to rotate. The fifth bevel gear 428 rotates with the sixth bevel gear 429, so that the fifth bevel gear 428 drives the third transmission shaft 427 to rotate, and then drives the fourth bevel gear 426 to rotate, so that the fourth bevel gear 426 drives the third bevel gear 425 to rotate, so that the third bevel gear 425 drives the worm 424 to rotate, so that the worm 424 drives the worm gear 423 to rotate, so that the worm gear 423 drives the second transmission shaft 422 to rotate coaxially, so that the second transmission shaft 422 drives the bracket 421 to rotate along the axis of the second transmission shaft 422, and then drives the blanking pipe 3 to rotate. Subsequently, due to the impact force of the water flow on the counterweight 65, the rack 62 slides on the sliding groove 51, thereby driving the third gear 61 to rotate, so that the third gear 61 drives the fifth transmission shaft 436 to rotate, and the fifth transmission shaft 436 drives the first gear 434 to rotate, so that the fourth transmission shaft 431 rotates, thereby driving the sixth bevel gear 429 to rotate, and adjusting the angle of the blanking pipe 3 again. The motor 135 drives the sixth transmission shaft 132 to rotate, so that it drives the baffle 12 to rotate, thereby opening and closing the loading box 11, and thus carrying out stone throwing.
