Description

Technical Field

[0001] This application relates to the field of ship cabin cleaning technology, and more particularly to a ship cabin bulkhead cleaning device. Background Technology

[0002] When ships transport bulk cargo (such as coal and mineral powder) to ports, they typically use unloaders and loaders equipped with buckets to unload the materials and transfer them to the quay. However, coal and mineral powder become less fluid when damp and tend to adhere to the ship's bulkheads, preventing some materials from being unloaded smoothly. If the ship's hold is not cleaned after unloading, the remaining material may affect the purity of subsequent loadings of different cargoes or cause mixing problems. Therefore, cleaning the ship's hold after each unloading is crucial.

[0003] To facilitate the cleaning of ship holds after each unloading, technicians have developed related cleaning equipment. For example, the utility model patent with publication number CN211254517U relates to a cleaning device for ships carrying sticky and wet cargo. This device includes a connecting rod installed on a single tooth of a mechanical bucket and a scraper at the end of the connecting rod. The scraper is sized to reach into the narrow spaces within the ship hold where materials remain. By extending the scraper into any narrow space within the ship hold, the working of the bucket drives the connecting rod and the scraper to scrape away the sticky substances on the hold walls, thus completing the cleaning of that narrow space.

[0004] However, due to the complex structure of some ship compartments and the varying sizes of gaps, the cleaning equipment used in related technologies has small and fixed scrapers. For larger gaps, multiple scraping or replacement of scrapers is required, resulting in low cleaning efficiency. Utility Model Content

[0005] To address the issue of low cleaning efficiency in existing systems, this application provides a cleaning device that is highly practical and efficient.

[0006] This application provides a bulkhead cleaning device, which adopts the following technical solution:

[0007] A ship bulkhead cleaning device includes a vehicle body and a robotic arm mounted on the vehicle body. The robotic arm is equipped with a bucket, and the bucket is equipped with a cleaning head. The cleaning head includes a mounting part, a first scraper, a second scraper, and a third scraper integrally formed with the mounting part. The first scraper, the second scraper, and the third scraper are all in the shape of long plates, with the length of the first scraper being longer than that of the third scraper, and the length of the third scraper being longer than that of the second scraper.

[0008] With the above technical solution, during cleaning, the driver maneuvers the vehicle to the location to be cleaned and controls the robotic arm to move and rotate the bucket. The first scraper is used to remove large areas of adhesive material from the ship's bulkhead; the second scraper is used to reach into narrow spaces or crevices; and the third scraper is used to reach into small to medium-sized crevices, such as between adjacent ship keels. This eliminates the need for repeated scraping or replacement of scrapers, improving cleaning efficiency and ensuring a more thorough cleaning.

[0009] Preferably, the bucket includes a bucket body and a hinge portion disposed on one side of the bucket body. One side of the bucket body is an inclined side, which is inclined and extends outward. The hinge portion is opposite to the inclined side. The robotic arm is used to drive the bucket to move and rotate. The hinge portion is hinged to the robotic arm through a hinge shaft.

[0010] The above technical solution allows the inclined side to guide materials into the bucket. The mechanical arm drives the bucket to rotate, thereby achieving the shoveling action, which facilitates the collection of sticky materials into the bucket for transportation.

[0011] Preferably, one end of the second scraper extends out of the first scraper and is connected to one end of the mounting part, and one end of the third scraper extends out of the first scraper and is connected to the other end of the mounting part.

[0012] The above technical solution limits the sliding distance of the mounting part by using the second and third scraping parts to prevent the cleaning head from falling off.

[0013] Preferably, the cleaning head further includes a scraper-shaped wear-resistant elastic element, which wraps around the first scraper, the second scraper, and the third scraper on the side away from the mounting part.

[0014] With the above technical solution, during cleaning, the wear-resistant elastic component helps to adapt to the unevenness of the bulkhead surface, thus closely adhering to the bulkhead surface and better scraping off the sticky material. At the same time, the elasticity of the wear-resistant elastic component effectively absorbs impact and friction, reducing wear when in contact with the hull and preventing damage to the hull during the cleaning process.

[0015] Preferably, the wear-resistant elastic element is made of silicone.

[0016] Through the above technical solutions, silicone, with its excellent elasticity and wear resistance, as well as its excellent tolerance to a variety of chemicals, can effectively avoid reacting with viscous substances and is suitable for various application scenarios that require durability and stability.

[0017] Preferably, the bucket body has a mounting hole, the mounting part has a connecting hole, the bucket body is provided with a first bolt, the connecting hole is a threaded hole, and the first bolt is threadedly engaged with the connecting hole.

[0018] With the above technical solution, during adjustment, the position of the cleaning head is adjusted by sliding the drive mounting part, thereby adjusting the positions of the first scraper, second scraper, and third scraper to accommodate gaps of different depths and ensure thorough cleaning of the entire ship's hold. During installation, when the drive mounting part aligns the connecting hole with the mounting hole, the first bolt is inserted into the mounting hole and the connecting hole to fix the mounting part to the bucket body.

[0019] Preferably, multiple mounting holes are provided, and the multiple mounting holes are arranged at equal intervals along the sliding direction of the mounting part. Several connecting holes are provided, and the number of connecting holes is greater than the number of mounting holes. The several connecting holes are arranged at equal intervals along the sliding direction of the mounting part, and the distance between two adjacent mounting holes is equal to the distance between two adjacent connecting holes. The number of mounting holes corresponds to the number of first bolts.

[0020] By using the above technical solution, the sliding of the driving mounting part makes the multiple adjacent connecting holes aligned with the multiple mounting holes one by one, and by inserting the multiple first bolts into the multiple mounting holes one by one, and the multiple first bolts into the multiple connecting holes one by one, the installation becomes more stable.

[0021] Preferably, the first scraping part is further provided with a piercing rod, the piercing rod including a piercing part and a limiting part connected to one end of the piercing part, the end of the piercing part away from the limiting part is provided with an inclined surface, the limiting part and the piercing part are on the same central axis, and the radius of the limiting part is larger than the radius of the piercing part.

[0022] With the above technical solution, when loosening sticky materials, the inclined tip of the puncturing part is used to puncture them. The inclined tip provides concentrated and precise impact force, which helps to break up agglomerates or compacted areas in the material.

[0023] Preferably, the wear-resistant elastic element has a through hole, the first scraping part has a first sliding groove that communicates with the through hole, and the piercing part slides and engages with the first sliding groove and the through hole; a second sliding groove is formed at the bottom of the first sliding groove that communicates with the first sliding groove, and the limiting part slides and engages with the second sliding groove; when the limiting part slides to its minimum distance, the limiting part abuts against the second sliding groove and is away from the groove wall of the first sliding groove, and the inclined surface of the piercing part is on the same plane as the wear-resistant elastic element; when the limiting part slides to its maximum distance, the limiting part abuts against the second sliding groove and is close to the groove wall of the first sliding groove, at which time the inclined surface of the piercing part extends out of the wear-resistant elastic element.

[0024] With the above technical solution, when the inclined surface of the puncturing part is on the same plane as the wear-resistant elastic element, it ensures that the wear-resistant elastic element adheres to the surface of the bulkhead for scraping. When the inclined surface of the puncturing part extends beyond the wear-resistant elastic element, it punctures the sticky material to loosen it.

[0025] Preferably, the first scraping part has a through hole that connects to the first sliding groove, and the piercing part has a first positioning hole and a second positioning hole. Both the first positioning hole and the second positioning hole are threaded holes and are spaced apart along the length of the piercing part. The cleaning head is also provided with a second bolt, which is threaded into both the first positioning hole and the second positioning hole. When the limiting part slides to its minimum distance, the through hole and the first positioning hole are aligned. When the limiting part slides to its maximum distance, the through hole and the second positioning hole are aligned.

[0026] With the above technical solution, when loosening sticky materials, the mechanical arm drives the bucket to rotate. Under gravity, the limiting part slides to its maximum distance, at which point the through hole and the second positioning hole align. A second bolt is inserted into the through hole and the second positioning hole to fix the piercing rod, allowing the inclined surface of the piercing part to extend beyond the wear-resistant elastic element. This allows the piercing part to pierce the sticky material, facilitating its loosening. After completion, the limiting part slides to its minimum distance, aligning the through hole and the first positioning hole. A second bolt is then inserted into the through hole and the first positioning hole to fix the piercing rod. The inclined surface of the piercing part remains on the same plane as the wear-resistant elastic element, facilitating further scraping operations.

[0027] Compared with the prior art, this application has the following beneficial effects:

[0028] During cleaning, the driver operates the vehicle to the location to be cleaned and controls the robotic arm to move and rotate the bucket. The first scraper removes large areas of sticky material from the ship's bulkhead, the second scraper reaches into narrower spaces or gaps, and the third scraper reaches into small to medium-sized gaps, such as between two adjacent ship keels. This eliminates the need for repeated scraping or replacement of scrapers, improving cleaning efficiency and making the cleaning more thorough.

[0029] Wear-resistant elastic components help adapt to the unevenness of the bulkhead surface, thus closely adhering to the bulkhead surface and making it easier to scrape off sticky substances. At the same time, the elasticity of the wear-resistant elastic components effectively absorbs impact and friction, reducing wear when in contact with the hull and preventing damage to the hull during the cleaning process.

[0030] 3. When loosening sticky materials, the mechanical arm drives the bucket to rotate. Under gravity, the limiting part slides to its maximum distance. At this time, the through hole and the second positioning hole are aligned. The second bolt is inserted into the through hole and the second positioning hole to fix the piercing rod, so that the inclined surface of the piercing part extends out of the wear-resistant elastic element. The piercing part pierces the sticky material to loosen it. After completion, the limiting part is driven to slide to its minimum distance, the through hole and the first positioning hole are aligned. The second bolt is inserted into the through hole and the first positioning hole to fix the piercing rod. The inclined surface of the piercing part and the wear-resistant elastic element are kept on the same plane to facilitate other scraping work. Attached Figure Description

Detailed Implementation

[0038] The following will refer to the appendices in the embodiments of this application. Figures 1 to 5The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] A bulkhead cleaning device, as described in the following text Figure 1 The system includes a vehicle body 1, a robotic arm 2 mounted on the vehicle body 1, and a bucket 3 rotatably mounted at the end of the robotic arm 2. The vehicle body 1 is used by the driver to operate and control the robotic arm 2. The robotic arm 2 is electrically connected to the vehicle body 1 and drives the bucket 3 to move and rotate. The robotic arm is positioned on one side of the vehicle body 1, allowing the driver to control the robotic arm 2 through the vehicle body 1. The vehicle body 1 and robotic arm 2 are relatively mature technologies in the prior art and will not be described in detail here. During operation, the driver drives the vehicle body 1 to the location to be cleaned and controls the robotic arm 2, causing it to move and rotate the bucket 3, thus achieving the material-shoveling action.

[0040] Reference Figure 1 and Figure 2 The bucket 3 includes a bucket body 31 and a hinge portion 32 disposed on one side of the bucket body 31. In this embodiment, the bucket body 31 is a square bucket, and one short side of the bucket body 31 is an inclined side. The inclined side is inclined and extends outward, which is beneficial for guiding materials into the bucket body 31. The hinge portion 32 is approximately the shape of the letter B and is plate-shaped. The hinge portion 32 is away from the inclined side. The hinge portion 32 is hinged to the robotic arm 2 through a hinge shaft. The robotic arm 2 is respectively hinged to the two bends of the B-shaped hinge portion 32. That is, when the robotic arm 2 drives the bucket 3 to rotate along one of the hinge points, the bucket 3 rotates at the same time along the other hinge point, so that the bucket 3 rotates as a whole, realizing the action of scooping material, thereby conveniently collecting sticky materials into the bucket body 31 and transporting them.

[0041] Reference Figure 2 and Figure 3 The bucket body 31 is detachably connected to a cleaning head 4. The cleaning head 4 includes a mounting part 41, a first scraper 42, a second scraper 43, and a third scraper 44 integrally formed with the mounting part 41. A mounting groove 16 is provided at one end extending outwards on the inclined side. The mounting groove 16 is elongated and has a T-shaped cross-section, extending through the bucket body 31 along its width. The mounting part 41 is a T-shaped long plate, longer than the mounting groove 16. The mounting part 41 and the mounting groove 16 slide and engage along the width of the bucket body 31, preventing the mounting part 41 from sliding along the length of the bucket body 31.

[0042] Reference Figure 2 and Figure 3The first scraper 42, the second scraper 43, and the third scraper 44 are all elongated plates, with the first scraper 42 being longer than the third scraper 44, and the third scraper 44 being longer than the second scraper 43. The first scraper 42 is distributed along the length of the mounting portion 41. The second scraper 43 is located at one end of the first scraper 42 and is distributed along the width of the first scraper 42. One end of the second scraper 43 extends out of the first scraper 42 and connects to one end of the mounting portion 41. The third scraper 44 is also located at one end of the first scraper 42 and away from the second scraper 43. The third scraper 44 is also distributed along the width of the first scraper 42, with one end extending out of the first scraper 42 and connecting to the other end of the mounting portion 41. The second scraper 43 and the third scraper 44 limit the sliding distance of the mounting portion 41, preventing the cleaning head 4 from falling off.

[0043] During cleaning, the driver operates the vehicle 1 to the location to be cleaned and controls the robotic arm 2, which moves and rotates the bucket 3. The first scraper 42 is used to scrape away large areas of adhesive material from the ship's bulkhead; the second scraper 43 is used to reach into narrower spaces or crevices; and the third scraper 44 is used to reach into small to medium-sized crevices, such as between adjacent ship keels, thereby improving cleaning efficiency and making the cleaning more thorough.

[0044] In addition, refer to Figure 2 and Figure 3 The cleaning head 4 also includes a scraper-shaped wear-resistant elastic element 45. The wear-resistant elastic element 45 wraps around the first scraper part 42, the second scraper part 43, and the third scraper part 44 on the side away from the mounting part 41. During cleaning, the wear-resistant elastic element 45 helps adapt to the unevenness of the bulkhead surface, thus closely adhering to the bulkhead surface and better scraping away sticky substances. Simultaneously, the elasticity of the wear-resistant elastic element 45 effectively absorbs impact and friction, reducing wear when in contact with the hull and preventing damage to the hull during cleaning. In this embodiment, the wear-resistant elastic element 45 is made of silicone. Silicone, due to its excellent elasticity and wear resistance, as well as its excellent resistance to various chemicals, can effectively prevent reaction with sticky substances, making it suitable for various applications requiring durability and stability.

[0045] Reference Figure 2 and Figure 3The bucket body 31 has a mounting hole 5 on the side near the mounting groove 16. The mounting hole 5 is circular, and multiple mounting holes 5 are provided, arranged at equal intervals along the length of the mounting groove 16. In this embodiment, three mounting holes 5 are provided, that is, three mounting holes 5 are arranged at equal intervals along the width of the bucket body 31. The mounting part 41 has several connecting holes 6, which are distributed at equal intervals along the length of the mounting part 41, and the distance between two adjacent mounting holes 5 is equal to the distance between two adjacent connecting holes 6. A first bolt 7 is provided on the bucket body 31, and the connecting holes 6 are threaded holes. The first bolt 7 is threaded into the connecting holes 6. When the mounting part 41 is driven to slide along the width of the bucket body 31, the connecting holes 6 are aligned with the mounting holes 5. By inserting the first bolt 7 into the mounting holes 5 and the connecting holes 6, the mounting part 41 is fixed to the bucket body 31.

[0046] Reference Figure 2 and Figure 3 The number of mounting holes 5 corresponding to the first bolt 7 is set to three. By driving the mounting part 41 to slide along the width direction of the bucket body 31, the three adjacent connecting holes 6 are aligned one-to-one with the three mounting holes 5. By inserting the three first bolts 7 one-to-one into the three mounting holes 5 and the three connecting holes 6 one-to-one into the three connecting holes 6, the installation is made more stable. Thus, by driving the mounting part 41 to slide along the width direction of the bucket body 31, the positions of the first scraper 42, the second scraper 43, and the third scraper 44 can be adjusted to adapt to gaps of different depths, ensuring a thorough cleaning of the entire ship's hold.

[0047] In addition, refer to Figure 4 and Figure 5 In order to better loosen the sticky material, the first scraper 42 is also provided with a poking rod 8. The poking rod 8 includes a poking part 81 and a limiting part 82 connected to one end of the poking part 81. The poking part 81 is a circular long rod, and the end of the poking part 81 away from the limiting part 82 is provided with an inclined surface. The limiting part 82 is a circular block. The limiting part 82 and the poking part 81 are on the same central axis, and the radius of the limiting part 82 is larger than the radius of the poking part 81.

[0048] Reference Figure 4 and Figure 5A through hole 9 is provided on the wear-resistant elastic element 45, and the through hole 9 is adapted to the puncturing part 81. A first sliding groove 10 is provided on the first scraping part 42 corresponding to the through hole 9. The first sliding groove 10 is circular and distributed along the width direction of the first scraping part 42. The first sliding groove 10 is also adapted to the puncturing part 81 and is connected to the through hole 9, so that the puncturing part 81 slides along the width direction of the first scraping part 42 and is fitted into the first sliding groove 10 and the through hole 9. A second sliding groove 11 is provided at the bottom of the first sliding groove 10. The second sliding groove 11 is also circular and is distributed along the width direction of the first scraping part 42. The second sliding groove 11 is adapted to the limiting part 82 and is connected to the first sliding groove 10. The limiting part 82 slides along the width direction of the first scraping part 42 and is fitted into the second sliding groove 11.

[0049] Reference Figure 4 and Figure 5 When the limiting part 82 slides to its minimum distance along the width direction of the first scraper part 42, the limiting part 82 abuts against the second slide groove 11 and is away from the groove wall of the first slide groove 10. At this time, the inclined surface of the striking part 81 is on the same plane as the wear-resistant elastic member 45. When the limiting part 82 slides to its maximum distance along the width direction of the first scraper part 42, the limiting part 82 abuts against the second slide groove 11 and is close to the groove wall of the first slide groove 10. At this time, the inclined surface of the striking part 81 extends out of the wear-resistant elastic member 45. Furthermore, by driving the robotic arm 2, the robotic arm 2 drives the bucket 3 to rotate. Through gravity, the limiting part 82 can slide to its maximum distance along the width direction of the first scraper part 42.

[0050] Reference Figure 5The first scraper 42 has a through hole 12, which is circular and connects to the first sliding groove 10. The piercing part 81 has a first positioning hole 13 and a second positioning hole 14, both of which are threaded holes, and are spaced apart along the length of the piercing part 81. The cleaning head 4 also has a second bolt 15, which is threaded into both the first positioning hole 13 and the second positioning hole 14. Furthermore, when the limiting part 82 slides to the minimum distance along the width direction of the first scraper 42, the through hole 12 and the first positioning hole 13 are aligned with each other. The second bolt 15 is inserted into the through hole 12 and the first positioning hole 13 to fix the piercing rod 8. The inclined surface of the piercing part 81 is kept on the same plane as the wear-resistant elastic member 45, thereby ensuring that the wear-resistant elastic member 45 is in contact with the surface of the adhering chamber wall for scraping. When the limiting part 82 slides to the maximum distance along the width direction of the first scraper 42, the through hole 12 and the second positioning hole 14 are aligned with each other. The second bolt 15 is inserted into the through hole 12 and the second positioning hole 14 to fix the piercing rod 8. The inclined surface of the piercing part 81 extends out of the wear-resistant elastic member 45, thereby piercing the sticky material through the piercing part 81. The tip of the inclined surface provides a concentrated and precise impact force, which helps to break up the agglomerated or compacted areas in the material, so as to loosen the sticky material.

[0051] When loosening sticky materials, the driver moves the vehicle 1 to the designated position. The mechanical arm 2 rotates the bucket 3, and gravity causes the limiting part 82 to slide to its maximum distance along the width of the first scraping part 42. At this point, the through hole 12 aligns with the second positioning hole 14. A second bolt 15 is inserted into the through hole 12 and the second positioning hole 14 to fix the piercing rod 8, allowing the inclined surface of the piercing part 81 to extend out of the wear-resistant elastic element 45. The piercing part 81 then pierces the sticky material to loosen it. After this, the limiting part 82 slides to its minimum distance along the width of the first scraping part 42, aligning the through hole 12 with the first positioning hole 13. A second bolt 15 is inserted into the through hole 12 and the first positioning hole 13 to fix the piercing rod 8. The inclined surface of the piercing part 81 remains on the same plane as the wear-resistant elastic element 45, facilitating further scraping work.

[0052] The implementation principle of this application is as follows: When loosening sticky materials, the mechanical arm 2 is driven to rotate the bucket 3. Under the action of gravity, the limiting part 82 slides to its maximum distance along the width direction of the first scraping part 42. At this time, the through hole 12 and the second positioning hole 14 are aligned with each other. The second bolt 15 is inserted into the through hole 12 and the second positioning hole 14 to fix the piercing rod 8, so that the inclined surface of the piercing part 81 extends out of the wear-resistant elastic member 45. The piercing part 81 then pierces the sticky material to loosen it. After completion, the limiting part 82 is driven to slide to its minimum distance along the width direction of the first scraping part 42. The through hole 12 and the first positioning hole 13 are aligned with each other. The second bolt 15 is inserted into the through hole 12 and the first positioning hole 13 to fix the piercing rod 8. The inclined surface of the piercing part 81 and the wear-resistant elastic member 45 remain on the same plane to facilitate other scraping operations.

[0053] During cleaning, the driver operates the vehicle 1 to the location to be cleaned and controls the robotic arm 2 to move and rotate the bucket 3. The position of the cleaning head 4 is adjusted by sliding the drive mounting part 41 along the width of the bucket 31, thereby adjusting the positions of the first scraper 42, the second scraper 43, and the third scraper 44 to accommodate gaps of different depths.

[0054] The first scraper 42 facilitates the removal of sticky substances from the bulkhead over large areas. The second scraper 43 allows it to reach into narrower spaces or crevices. The third scraper 44 allows it to reach into small to medium-sized crevices, such as between two adjacent bulkhead keels. At the same time, it ensures that the wear-resistant elastic parts fit tightly against the bulkhead surface, thereby better removing sticky substances. This eliminates the need for repeated scraping or replacement of scrapers, improving cleaning efficiency and making the cleaning more thorough.

[0055] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
