Description

Technical Field

[0001] The present invention belongs to the technical field of anchoring devices, and specifically relates to an anchoring device for a dredger. Background Art

[0002] A dredger is an engineering ship specifically used for dredging water areas. Its main function is to remove sediments such as sand, silt, and rocks at the bottom of the water by mechanical or hydraulic means to maintain or improve the navigation conditions of the water area. When the dredger is operating, the anchoring device can ensure the stability of the ship and prevent displacement caused by factors such as water flow and wind waves.

[0003] The patent with the publication number CN220076620U discloses a ship docking and anchoring device, belonging to the technical field of anchoring devices, including an anchor bin fixed on the ship board. A winding mechanism is arranged in the anchor bin. The winding mechanism includes a rotating rod, which is coaxially and fixedly connected to the output shaft of the motor. A winding wheel is rotatably installed in the anchor bin, and the winding wheel is coaxially and fixedly connected to the rotating rod. A chain is arranged on the winding wheel, and one end of the chain is provided with a ship anchor. A sorting mechanism is arranged in the anchor bin. The sorting mechanism includes a first sprocket, which is coaxially and fixedly connected to a second bevel gear. A second sprocket is rotatably installed in the anchor bin. The same chain is installed on the first sprocket and the second sprocket, and a cleaning sleeve is arranged on the chain. The chain passes through the cleaning sleeve; the cooperation of the winding wheel and the chain in the winding mechanism can quickly wind and unwind the ship anchor, facilitating quick anchoring. The setting of the cleaning sleeve can sort the chain, making the winding of the chain smoother, and can scrape off the dirt on the chain, which can better protect the anchor chain of the ship anchor.

[0004] However, the above technical solution still has the following deficiencies in actual application: The anchor chain is unwound by using the winding wheel to make the anchor chain enter the water. Since there are aquatic plants in the water, such as waterweeds, reeds, etc., the aquatic plants in the water are easy to float with the water flow and wind around the surface of the anchor chain. When the anchor chain is wound, the anchor chain will carry these aquatic plants and move to the winding wheel, thereby increasing the friction between the anchor chain and the winding wheel, resulting in an increase in resistance and a decrease in smoothness during unwinding, affecting subsequent use.

[0016] The beneficial effects of the present invention are as follows: 1. For the dredger anchor throwing device of the present invention, by using the hooking component, when the anchor chain is wound up, with the cooperation of multiple elastic claws and the rotating plate, the aquatic plants wound around the anchor chain can be hooked off, avoiding the situation that when the aquatic plants are wound on the surface of the anchor chain and the anchor chain is wound up, the anchor chain carries these aquatic plants and moves to the winding wheel, thereby increasing the friction between the anchor chain and the winding wheel, resulting in an increase in resistance and a decrease in smoothness during unwinding, affecting subsequent use.

[0017] 2. For the dredger anchor throwing device of the present invention, by using the self-cleaning component, when the elastic claws and the rotating plate hook the aquatic plants wound around the anchor chain, it can achieve a real-time cleaning effect on the surfaces of the elastic claws and the scraping plate, avoiding the situation that after the elastic claws hook the aquatic plants, the subsequent hooking effect is affected due to the aquatic plants covering the elastic claws or the rotating plate.

[0018] 3. When removing the aquatic plants wound on the surface of the anchor chain for the dredger anchor throwing device of the present invention, it is carried out in the housing. The housing can provide a wind protection effect on a part of the anchor chain, avoiding the situation that the part of the anchor chain being hooked sways due to the wind and is not easily contacted by the elastic claws, ensuring the smooth progress of the hooking work. Moreover, by using the limiting component, when the anchor chain is wound up, both ends of the part of the anchor chain in the housing are in contact with the limiting balls. And under the transmission of the slider, the connecting rod, and the rotating ring, multiple limiting balls will closely fit with the surface of the anchor chain under the action of the spring, making the anchor chain in the middle position of the through hole of the housing. Thus, it can not only use the housing to prevent the anchor chain from being blown by the wind, but also avoid the situation that when the anchor chain is wound up, the anchor chain is stuck at the through holes on the upper and lower sides of the housing due to contact with the hole wall of the through hole of the housing, thereby ensuring the normal winding of the anchor chain.

[0019] 4. The anchor - dropping device of the dredger described in the present invention utilizes the aggregation component to remove the aquatic plants that are hooked down by the elastic claws and are at the bottom of the inner cavity of the housing in real - time, avoiding the situation that the elastic claws contact the aquatic plants that have already been scraped off again due to the accumulation of aquatic plants in the housing, which affects the scraping effect of the subsequent elastic claws on the aquatic plants wound around the surface of the anchor chain. Moreover, since the aquatic plants in the housing converge first and then are discharged, the discharge range of the aquatic plants is small, and accordingly, the area of the discharge port is also small. Thus, when the aquatic plants are discharged from the housing, due to the overly large discharge port, more air enters the housing, and the situation that the part of the anchor chain in the housing affects the normal operation of the elastic claws due to swinging is avoided again.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Next, in conjunction with the accompanying drawings, the technical solution of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-10 , the present invention provides a technical solution: a dredger anchor device, including a frame body 34 and a housing 4. One side of the upper end of the frame body 34 is rotatably provided with a winding wheel 1. An anchor chain 3 is wound around the winding wheel 1. An anchor head 5 is arranged at the end of the anchor chain 3. The anchor chain 3 passes through the through holes on the upper and lower sides of the housing 4. An installation plate 17 is arranged on one side of the housing 4. The housing 4 is also provided with a hooking component for removing aquatic plants wound around the anchor chain 3; The hooking component includes a plurality of support rods 18 fixedly connected to the upper end face of the inner cavity wall of the housing 4. One side of the lower end of the support rod 18 is rotatably provided with a rotating plate 20. One end of the rotating plate 20 is fixedly connected with an elastic claw 21; The upper and lower sides of the housing 4 are also provided with a limiting component for keeping the part of the anchor chain 3 in the housing 4 stable; The limiting component includes a plurality of sliders 27 rotatably arranged in an array around the axis of the housing 4. A limiting ball 28 is rotatably arranged on one side of the slider 27.

[0025] In this embodiment, as Figure 2 , Figure 4 , Figure 5 shown, one side of the upper end of the frame body 34 is fixedly connected with a first motor 2. The output end of the first motor 2 is fixedly connected with the winding wheel 1.

[0026] One side of the lower end of the support rod 18 is fixedly connected with a third motor 19. The output end of the third motor 19 is fixedly connected with one end of the rotating plate 20.

[0027] Specifically, when the existing anchor device is in use, the winding wheel 1 is used to unwind the anchor chain 3 so that the anchor chain 3 enters the water. Since there are aquatic plants in the water, such as waterweeds, reeds, etc., the aquatic plants in the water are easily drifted by the water flow and wound around the surface of the anchor chain 3. When the anchor chain 3 is wound up, the anchor chain 3 will carry these aquatic plants and move to the winding wheel 1, thereby increasing the friction between the anchor chain 3 and the winding wheel 1, resulting in an increase in resistance and a decrease in smoothness during unwinding, affecting subsequent use; Therefore, to solve the above problems, when this embodiment is in use, the frame 34 and the mounting plate 17 are installed on the dredger, and the anchor chain 3 always passes through the through holes on the upper and lower sides of the housing 4. When the dredger needs to dock for operation, the first motor 2 drives the winding wheel 1 to rotate, and the winding wheel 1 unwinds the wound anchor chain 3 until the anchor head 5 sinks to the bottom of the water, so that the dredger can be kept stable. After the operation is completed, the winding wheel 1 is driven to rotate again to wind the anchor chain 3. During the winding process of the anchor chain 3, multiple third motors 19 are started simultaneously. The third motors 19 drive the rotating plate 20 to rotate. When the rotating plate 20 rotates, the elastic claws 21 at its end will contact the anchor chain 3. Since the elastic claws 21 and the rotating plate 20 have an included angle, the elastic claws 21 will have a hooking effect on the aquatic plants wound on the anchor chain 3. And the elastic claws 21 are made of flexible materials, which will not interfere with the movement of the anchor chain 3 and are not easily damaged. Thus, with the cooperation of multiple elastic claws 21 and the rotating plate 20, the aquatic plants wound on the anchor chain 3 are hooked off, avoiding the situation that when the anchor chain 3 is wound, the anchor chain 3 carries these aquatic plants and moves to the winding wheel 1, which increases the friction between the anchor chain 3 and the winding wheel 1, resulting in an increase in resistance and a decrease in smoothness during unwinding, affecting subsequent use.

[0028] In this embodiment, as Figure 5 shown, a self-cleaning component is also provided on the rotating plate 20; The self-cleaning component includes a second cylinder 23 fixedly connected to one side of the rotating plate 20. The piston end of the second cylinder 23 is fixedly connected with a scraper 22. The scraper 22 is sleeved on the rotating plate 20 and is slidably connected thereto.

[0029] Specifically, in the above embodiment, although the elastic claws 21 can be used to scrape off the aquatic plants wound around the surface of the anchor chain 3, after the elastic claws 21 hook the aquatic plants, the aquatic plants may cover the elastic claws 21 or the rotating plate 20, resulting in the difficulty for the elastic claws 21 and the rotating plate 20 to scrape the aquatic plants again, affecting subsequent use. Therefore, to avoid this problem, every time the rotating plate 20 and the elastic claws 21 complete a scraping action and move away from the anchor chain 3, the cylinder two 23 drives the scraper 22 to move along the surface of the rotating plate 20, forming a scrape with the surface of the rotating plate 20. At the same time, since the elastic claws 21 are elastic, the elastic claws 21 will also be flattened under the action of the scraper 22 until the scraper 22 reaches the end position of the elastic claws 21, and the aquatic plants covering the elastic claws 21 or the rotating plate 20 are scraped off. Then the scraper 22 resets, and the elastic claws 21 recover. Then, by continuously repeating the above operations, the surfaces of the elastic claws 21 and the scraper 22 can be cleaned in real time, avoiding the situation that after the elastic claws 21 hook the aquatic plants, due to the aquatic plants covering the elastic claws 21 or the rotating plate 20, it is difficult for the elastic claws 21 and the rotating plate 20 to form a hooking effect on the aquatic plants wound around the anchor chain 3, thereby affecting subsequent use.

[0030] In this embodiment, as Figure 2 , Figure 7 , Figure 8 shown, one end of the slider 27 is rotatably provided with a connecting rod 26, one end of the connecting rod 26 is rotatably provided with a rotating ring 6, the rotating ring 6 is rotatably provided with a fixed ring 7, and one side of the fixed ring 7 is fixedly connected to the housing 4.

[0031] One side of the rotating ring 6 is fixedly connected with a chute rod 30. A guide post 31 is inserted into and slidably connected to the chute of the chute rod 30. One end of the guide post 31 is fixedly connected with a displacement block 32. The displacement block 32 is slidably connected to the housing 4. One side of the displacement block 32 is fixedly connected with a spring 29, and the other end of the spring 29 is fixedly connected to the housing 4. Push rods 33 are rotatably provided on the upper and lower end faces of the right side of the housing 4, and motors four 24 are fixedly connected to the upper and lower sides of the inner cavity of the housing 4. The output end of the motor four 24 is fixedly connected to one end of the push rod 33.

[0032] Specifically, since the dredger operates in water areas, and usually, the wind force is relatively strong around water areas. Therefore, when the anchor chain 3 is wound up, it is prone to swing due to the wind force, resulting in the elastic claw 21 not easily fitting with the surface of the anchor chain 3. So, to avoid this situation, when removing the aquatic plants wound around the surface of the anchor chain 3, it is carried out in the housing 4. The housing 4 can provide a wind protection effect for the local part of the anchor chain 3 to ensure the smooth progress of the hooking operation. Since there is a through hole provided on the upper side of the housing 4, when the anchor chain 3 passes through the through hole, due to the special shape of the anchor chain 3, when the anchor chain 3 contacts the hole wall of the through hole of the housing 4, it is easy to get hooked at the through hole of the housing 4, resulting in the anchor chain 3 being stuck during the winding process and affecting the normal winding of the anchor chain 3. So, to avoid this problem, when the anchor chain 3 is wound up, both ends of the part of the anchor chain 3 in the housing 4 are in contact with the limiting balls 28. And under the transmission of the slider 27, the connecting rod 26, and the rotating ring 6, the plurality of limiting balls 28 will fit with the surface of the anchor chain 3 under the action of the spring 29, making the anchor chain 3 in the middle position of the through hole of the housing 4. Thus, it can not only use the housing 4 to prevent the anchor chain 3 from being blown by the wind but also avoid the anchor chain 3 being stuck at the through holes on the upper and lower sides of the housing 4, ensuring the normal winding of the anchor chain 3. To avoid the difficulty in observing the instruction drawings, only one set of the limiting components is shown in the drawings and is located above the housing 4; When the anchor chain 3 is unwound, the push rod 33 can be driven to rotate by the fourth motor 24, so that the push rod 33 contacts the displacement block 32, the displacement block 32 slides, and the limiting balls 28 move away from the anchor chain 3, thereby reducing the friction between the limiting balls 28 and the anchor chain 3 and being beneficial to extending the service life of the limiting balls 28 and the anchor chain 3.

[0033] In this embodiment, as Figures 2-4 、 Figure 6 、 Figure 10 shown, an aggregation component is further arranged in the inner cavity of the housing 4; The aggregation component is fixedly connected to the surrounding plate 11 at the bottom of the inner cavity wall of the housing 4. Aggregation plates 8 are inserted and slidably connected to both sides of the surrounding plate 11. Surrounding blocks 12 are slidably connected to both sides of the lower end face of the inner cavity wall of the housing 4. A first cylinder 16 is fixedly connected to the upper end face of the surrounding block 12, and the piston end of the first cylinder 16 is fixedly connected to one end of the aggregation plate 8.

[0034] A gear ring 13 is fixedly connected to the middle of the lower end face of the inner cavity of the housing 4. A gear 14 is rotatably arranged on one side of the surrounding block 12. The gear 14 meshes with the outer ring teeth of the gear ring 13. A second motor 15 is fixedly connected to one side of the surrounding block 12, and the output end of the second motor 15 is fixedly connected to the gear 14.

[0035] A discharge port 9 is arranged on one side of the bottom of the housing 4. A baffle 10 is rotatably arranged on one side of the lower end face of the housing 4. When the baffle 10 rotates, it covers the discharge port 9.

[0036] A motor 5 25 is fixedly connected to one side of the lower end surface of the shell 4 , and an output end of the motor 5 25 is fixedly connected to one end of the baffle 10 .

[0037] Specifically, in the above embodiment, although the shell 4 can be used to protect the anchor chain 3 from wind and prevent it from swinging, the aquatic plants that fall from the elastic claws 21 will also be in the inner cavity of the shell 4, resulting in the accumulation of aquatic plants in the shell 4. It is easy for the elastic claws 21 to contact the aquatic plants that have been scraped off again, which still affects the subsequent scraping effect of the elastic claws 21 on the aquatic plants. Therefore, in order to avoid this situation, when the present embodiment is in use, the two gathering plates 8 are on the same side and close to each other in the initial state, and the bottom of the gathering plates 8 is in contact with the bottom of the inner cavity wall of the shell 4. When the elastic claws 21 are working, the two motors 15 drive the two gears 14 to rotate in different directions at the same time, so that the two surrounding blocks 12 slide on the bottom of the inner cavity of the shell 4 and make a circular motion, so that the gathering plates 8 move to the other side of the inner cavity of the shell 4. During the movement of the gathering plates 8, the aquatic plants at the bottom of the inner cavity of the shell 4 will be pushed. Since the two gathering plates 8 first move away and then approach, the aquatic plants will gather at the discharge port 9, and the volume of the aquatic plants will be reduced. The aquatic plants at the bottom of the inner cavity of the shell 4 can be reduced in size. At this time, the motor 5 25 is used to drive the baffle 10 to rotate, and the aquatic plants fall out from the discharge port 9. Then the baffle 10 is closed, and the cylinder 16 drives the gathering plate 8 to rise, and the gathering plate 8 is reset. The gathering plate 8 rises first and then resets, which can avoid the aquatic plants that fall to the bottom of the inner cavity of the shell 4 being pushed back when the gathering plate 8 is reset. Then, the above operation is repeated to remove the aquatic plants at the bottom of the inner cavity of the shell 4 in real time, thereby avoiding the accumulation of aquatic plants in the shell 4, causing the elastic claws 21 to contact the aquatic plants that have been scraped off again, affecting the subsequent scraping effect of the elastic claws 21 on the aquatic plants entangled on the surface of the anchor chain 3. In addition, since the aquatic plants in the shell 4 are first gathered and then discharged, the discharge range of the aquatic plants is also small, and the corresponding discharge port 9 area is also small, thereby avoiding the situation that when the aquatic plants are discharged from the shell 4, the discharge port 9 is set too large, resulting in more wind entering the shell 4, and the part of the anchor chain 3 in the shell 4 swings again to affect the normal operation of the elastic claws 21.

[0038] Working principle: Install the frame 34 and the mounting plate 17 on the dredger, and the anchor chain 3 always passes through the through holes on the upper and lower sides of the housing 4. When the dredger needs to dock for operation, drive the winding wheel 1 to rotate by the first motor 2, and the winding wheel 1 pays out the wound anchor chain 3 until the anchor head 5 sinks to the bottom of the water, so that the dredger can be kept stable; after the operation is completed, drive the winding wheel 1 to rotate again and wind up the anchor chain 3. During the winding process of the anchor chain, start multiple third motors 19 at the same time. The third motors 19 drive the rotating plate 20 to rotate. When the rotating plate 20 rotates, the elastic claws 21 at its end will contact the anchor chain 3. Since the elastic claws 21 and the rotating plate 20 have an included angle, the elastic claws 21 will have a hooking effect on the aquatic plants wound on the anchor chain 3. Moreover, the elastic claws 21 are made of flexible materials, which will not interfere with the movement of the anchor chain 3 and are not easily damaged. Therefore, with the cooperation of multiple elastic claws 21 and the rotating plate 20, the aquatic plants wound on the anchor chain 3 are hooked off, avoiding the situation that when the aquatic plants are wound on the surface of the anchor chain 3 and the anchor chain 3 is wound up, the anchor chain 3 carries these aquatic plants and moves to the winding wheel 1, which increases the friction between the anchor chain 3 and the winding wheel 1, resulting in an increase in resistance and a decrease in smoothness during payout, affecting subsequent use;Whenever the rotating plate 20 and the elastic claw 21 complete a scraping action and move away from the anchor chain 3, the second cylinder 23 drives the scraper 22 to move along the surface of the rotating plate 20, forming a scrape with the surface of the rotating plate 20. At the same time, because the elastic claw 21 is elastic, the elastic claw 21 will also be flattened under the action of the scraper 22 until the scraper 22 reaches the end position of the elastic claw 21, then the aquatic plants covering the elastic claw 21 or the rotating plate 20 will be scraped off. Then the scraper 22 resets and the elastic claw 21 restores. Then, by continuously repeating the above operations, the surfaces of the elastic claw 21 and the scraper 22 can be cleaned in real time, avoiding the situation that after the elastic claw 21 hooks the aquatic plants, it is difficult for the elastic claw 21 and the rotating plate 20 to hook the aquatic plants wound around the anchor chain 3 due to the aquatic plants covering the elastic claw 21 or the rotating plate 20, which affects the subsequent use. When removing the aquatic plants wound around the surface of the anchor chain 3, it is carried out in the housing 4. The housing 4 can provide a windproof effect on a part of the anchor chain 3 to ensure the smooth progress of the hooking operation. Since there are through holes provided on the upper side of the housing 4, when the anchor chain 3 passes through the through holes, due to the special shape of the anchor chain 3, when the anchor chain 3 contacts the hole wall of the through hole of the housing 4, it is easy to be hooked at the through hole of the housing 4, resulting in the anchor chain 3 being stuck during the winding process, affecting the normal winding of the anchor chain 3. Therefore, to avoid this problem, when the anchor chain 3 is wound, both ends of the part of the anchor chain 3 in the housing 4 are in contact with the limit balls 28. And, under the transmission of the slider 27, the connecting rod 26, and the rotating ring 6, the plurality of limit balls 28 will fit with the surface of the anchor chain 3 under the action of the spring 29, making the anchor chain 3 in the center position of the through hole of the housing 4, so that the housing 4 can be used to prevent the anchor chain 3 from being blown by the wind and at the same time avoid the anchor chain 3 being stuck at the through holes on the upper and lower sides of the housing 4, ensuring the normal winding of the anchor chain 3; when the anchor chain 3 is unwound, the fourth motor 24 can drive the push rod 33 to rotate, so that the push rod 33 contacts the displacement block 32, the displacement block 32 slides, and the limit balls 28 move away from the anchor chain 3, thereby reducing the friction between the limit balls 28 and the anchor chain 3 and being beneficial to extending the service life of the limit balls 28 and the anchor chain 3;In the initial state, the two aggregation plates 8 are on the same side and close to each other. The bottom of the aggregation plate 8 is in contact with the bottom of the inner cavity wall of the housing 4. When the elastic claws 21 work, the two motors II 15 drive the two gears 14 to rotate simultaneously in different directions, causing the two surrounding blocks 12 to slide on the bottom of the inner cavity of the housing 4 and perform circular motion, so that the aggregation plate 8 moves to the other side of the inner cavity of the housing 4. During the movement of the aggregation plate 8, the aquatic plants at the bottom of the inner cavity of the housing 4 will be pushed. Since the two aggregation plates 8 first move away from each other and then approach each other, the aquatic plants will converge at the discharge port 9, and the volume of the aquatic plants will be reduced. At this time, the motor V 25 is used to drive the baffle 10 to rotate, and the aquatic plants will fall out from the discharge port 9. Then the baffle 10 closes, and the cylinder I 16 drives the aggregation plate 8 to rise, and the aggregation plate 8 returns to its original position. The aggregation plate 8 first rises and then returns to its original position, which can prevent the aggregation plate 8 from pushing back the subsequent aquatic plants that fall to the bottom of the inner cavity of the housing 4 when it returns to its original position. Then, by repeating the above operations, the aquatic plants at the bottom of the inner cavity of the housing 4 can be cleared in real time, avoiding the situation that the elastic claws 21 come into contact with the scraped aquatic plants again due to the accumulation of aquatic plants in the housing 4, which affects the scraping effect of the elastic claws 21 on the aquatic plants wound around the surface of the anchor chain 3. Moreover, since the aquatic plants in the housing 4 first converge and then are discharged, the discharge range of the aquatic plants is relatively small, and the area of the corresponding discharge port 9 is also relatively small, thus avoiding the situation that when the aquatic plants are discharged from the housing 4, due to the too large discharge port 9, more air enters the housing 4, and the part of the anchor chain 3 in the housing 4 swings again, affecting the normal operation of the elastic claws 21.;

What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
