Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to a cabin cleaning device based on a stainless steel chemical tanker. Background Art

[0002] Stainless steel chemical tankers, as special transport ships, are an important part of marine engineering equipment. They are mainly used to load and transport various liquid chemicals, including petrochemical products, organic chemicals, inorganic chemicals, etc. The cabin of the chemical tanker must be cleaned after each transportation mission. In order to avoid crew members being exposed to unsafe chemical working environments, tank cleaning robots are widely used as important equipment in the field of marine engineering equipment. With the help of remote control, these robots can be adsorbed on the bulkhead and move freely, and use high-pressure water jets to clean the cabin, effectively improving operational safety.

[0003] The wall-climbing robot disclosed in the existing publication number CN113060251A includes a frame, a cleaning mechanism, a driving mechanism, a permanent magnetic universal wheel and an arc magnet; the cleaning mechanism is installed on the frame; the driving mechanism includes two driving wheels, which are installed at the front end of the frame and symmetrically distributed on opposite sides of the frame; the permanent magnetic universal wheel is installed at the end of the frame; the arc magnet is installed at the front end of the frame and is located between the two driving wheels, the arc surface of the arc magnet is arranged to face forward and the magnetic force of the arc magnet decreases from top to bottom along the arc surface; although the above technical solution can walk on the complex surface of the cabin and can transition between walls with a certain inclination angle, it has the advantages of high safety and strong transition ability.

[0004] However, in the existing technology, current tank cleaning robots mostly adopt a fixed spray mode with a single or multiple nozzles. Although the high-pressure direct nozzle can generate a large positive impact force, it is difficult to destroy the internal structure and the intermolecular binding force with the surface of the tank bottom of the dense adhesion layer formed by high-viscosity chemicals on the tank bottom by relying solely on positive impact, resulting in poor cleaning effect. Although some tank cleaning robots are equipped with rotating spray arms to expand the cleaning coverage, the tangential flow rate generated by the rotating spray arms is limited, and it is impossible to form an effective shear force on the adhesion layer, making it difficult to remove stubborn stains. This problem of incomplete cleaning will not only affect the transportation quality of subsequent goods and cause product pollution, but also the long-term accumulation of residual high-viscosity chemicals will corrode the stainless steel material of the cabin and shorten the service life of the ship. In addition, repeated flushing of residual stains will also produce a large amount of chemical-containing wastewater, increasing the cost and pressure of subsequent environmental protection treatment. Summary of the Invention

At this time, water flows through the through hole, the first channel and the flow port in sequence, and is sprayed out through the front nozzle. When the adjusting disk is rotated to make the through hole and the second channel connected, the first channel is closed. At this time, water flows through the through hole and the second channel in sequence, and finally sprays out through the flow channel.

[0008] Furthermore, a driving mechanism is provided in the connecting tube, and the driving mechanism includes an impeller rotatably provided in the connecting tube, a rotating shaft fixed at the center of the impeller, and a connecting frame symmetrically fixed on the rotating shaft, the connecting frame is fixedly connected to the adjusting disk, a bracket is fixedly connected in the connecting tube, the rotating shaft is rotatably connected to the bracket, and a first torsion spring is provided on the rotating shaft.

[0009] Furthermore, a friction mechanism is provided in the connecting tube, and the friction mechanism includes a friction disk in friction contact with the impeller, an extension rod symmetrically fixed on the friction disk, and a vertical plate symmetrically fixed in the connecting tube, and the extension rods respectively pass through the corresponding vertical plates and are provided with springs.

[0010] Furthermore, an anti-slip pad is provided on the side where the friction disc and the impeller are close to each other.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1-Figure 2 A cabin cleaning device based on a stainless steel chemical tanker includes a robot body 100. A high-pressure water pipe 200 is provided on the robot body 100. A two-way pipe 300 is rotatably provided at the end of the high-pressure water pipe 200. A hydraulic cylinder assembly is provided on the high-pressure water pipe 200 to control the rotation of the two-way pipe 300 to achieve angle adjustment. A connecting pipe 400 is detachably installed on the two-way pipe 300, wherein one end of the connecting pipe 400 close to the two-way pipe 300 is a water inlet end, and the other end is a water outlet end. A front nozzle 500 is provided at the water outlet end of the connecting pipe 400. The high-pressure water pipe 200 provides high-pressure water for cleaning operations through an external pump.

[0022] Reference Figure 2-Figure 6 , also includes a centrifugal jet component 600, which is arranged on the connecting pipe 400. The centrifugal jet component 600 includes a diverter 601 fixed on the water outlet end of the connecting pipe 400 and a diverter channel 602 opened on the diverter 601. The diverter 601 is fixed on the front end nozzle 500, and the front end nozzle 500 has multiple groups of flow ports 603 opened along the circumferential direction. A centrifugal disk 604 is fixed outside the diverter 601, and multiple groups of flow channels 605 are opened on the centrifugal disk 604 along the circumferential direction, wherein the cross-section of the flow channel 605 is arc-shaped, and the arc-shaped structure can produce a centrifugal acceleration effect when the water flows through. An adjusting disk 606 is rotatably arranged in the connecting pipe 400, and the adjusting disk 606 is rotatably fitted on the surface of the diverter 601, and multiple groups of through holes 607 are opened on the adjusting disk 606 along the circumferential direction.

[0023] Specifically, the diversion channel 602 includes multiple groups of first channels 6021 and second channels 6022 arranged at intervals, and the number of first channels 6021 and second channels 6022 is equal, wherein the number of first channels 6021 and the flow ports 603 are consistent and correspond one-to-one, forming a water flow transmission path under the conventional direct jet cleaning mode, the number of second channels 6022 and the flow channels 605 are consistent and correspond one-to-one, forming a water flow transmission path under the centrifugal jet cleaning mode, the number of through holes 607 and the first channels 6021 is equal, and the opening and closing switching of different paths is realized by the rotation of the adjustment disk 606.

[0024] In the initial state, the through-hole 607 and the first channel 6021 are connected to each other, and the second channel 6022 is closed. High-pressure water passes through the through-hole 607, the first channel 6021 and the flow port 603 in sequence, and is ejected through the front nozzle 500. At this time, the water flow performs a preliminary cleaning of the cabin in a conventional direct injection mode, which is suitable for daily cleaning of most areas of the cabin. When encountering stubborn stains such as the high-viscosity chemical adhesion layer on the bottom of the cabin, the control dial 606 is controlled to rotate. When the through-hole 607 and the second channel 6022 are connected to each other, the first channel 6021 is closed. High-pressure water passes through the through-hole 607 and the second channel 6022 in sequence, and is finally ejected outward through the curved flow channel 605 on the centrifugal disk 604. Due to the curved structure of the flow channel 605, the water flow generates centrifugal force when passing through, forming a high-speed rotating centrifugal jet. The centrifugal jet not only has a greater impact force, but also generates a strong tangential shear force, achieving efficient removal of stubborn stains.

[0025] Reference Figure 4 、 Figure 7-Figure 9 , a driving mechanism 700 is provided in the connecting tube 400, and the driving mechanism 700 includes an impeller 701 rotatably provided in the connecting tube 400, a rotating shaft 702 fixed at the center of the impeller 701, and a connecting frame 703 symmetrically fixed on the rotating shaft 702, the connecting frame 703 is fixedly connected to the adjusting disk 606, a bracket 704 is fixedly connected in the connecting tube 400, the rotating shaft 702 passes through the center hole of the bracket 704, and is rotatably connected to the bracket 704, a first torsion spring 705 is provided on the rotating shaft 702, and the two ends of the first torsion spring 705 are respectively fixed to the connecting The frame 703 and the bracket 704 are connected to each other. Specifically, when it is necessary to clean the high-viscosity chemical adhesion layer on the bottom of the cabin, the operator increases the water pressure of the external pump, and the high-speed water flow impacts the impeller 701 to rotate it. The impeller 701 drives the adjusting disk 606 through the rotating shaft 702 and the connecting frame 703 to overcome the elastic force of the first torsion spring 705 and rotate until the through hole 607 is aligned with the second channel 6022, and switches to the centrifugal jet cleaning mode. When the water pressure drops, the first torsion spring 705 releases the elastic potential energy, drives the adjusting disk 606 to automatically reset, and returns to the conventional direct jet cleaning mode.

[0026] It should be noted that a slide post 706 is fixedly connected to the connecting frame 703, and a slideway 707 for the slide post 706 to slide is provided in the connecting tube 400. The function of the slide post 706 and the slideway 707 is to limit the rotation of the connecting frame 703 and the adjusting disk 606.

[0027] Further, refer to Figure 4 and Figure 8A friction mechanism 800 is also provided in the connecting tube 400. The friction mechanism 800 includes a friction disk 801 in friction contact with the impeller 701, an extension rod 802 symmetrically fixed on the friction disk 801, and a vertical plate 803 symmetrically fixed in the connecting tube 400. The extension rods 802 pass through the corresponding vertical plates 803 and are provided with springs 804. One end of the spring 804 rests on the inner side of the vertical plate 803, and the other end is in close contact with the side of the friction disk 801. The axial pressure is generated by the elastic deformation of the spring 804 to ensure that the friction force is maintained between the friction disk 801 and the impeller 701. The end of the extension rod 802 away from the friction disk 801 is fixedly connected to a stopper 805. The function of the stopper 805 is to prevent the extension rod 802 from separating from the corresponding vertical plate 803.

[0028] Among them, anti-skid pads are provided on the side where the friction disc 801 and the impeller 701 are close to each other, and the material of the anti-skid pads can be rubber.

[0029] Specifically, when the high-pressure water pipe 200 outputs normal water pressure, the friction disc 801 fits tightly against the back of the impeller 701 under the elastic action of the spring 804. At this time, the static friction between the two is greater than the torque of the conventional water flow pushing the impeller 701, and the impeller 701 remains stationary. As the water pressure increases, the impact force of the high-speed water flow on the impeller 701 increases, and at the same time, dynamic pressure is formed on the surface of the friction disc 801, pushing it to overcome the elastic force of the spring 804 and move along the extension rod 802. The positive pressure between the friction disc 801 and the impeller 701 decreases and the friction force decreases. When the water pressure reaches the preset threshold, the water flow driving torque exceeds the friction resistance, and the impeller 701 drives the rotating shaft 702 to rotate, and drives the adjusting disc 606 to rotate through the connecting frame 703 until the through hole 607 is aligned with the second channel 6022, closing the first channel 6021. The high-pressure water is ejected through the arc flow channel 605 of the centrifugal disc 604 to peel off the stubborn adhesion layer.

[0030] When the water pressure decreases, the water flow driving force weakens, the spring 804 pushes the friction disk 801 to reset and increases the friction force to stop the impeller 701, and the first torsion spring 705 drives the adjustment disk 606 to reset, restoring the water flow direct injection mode, completing the automatic switching of the cleaning mode.

[0031] Further, refer to Figure 10-12A wrapping shell 608 is fixed on the outside of the centrifugal disc 604, and the wrapping shell 608 is provided with outlets 609 corresponding to and the same in number as the flow channel 605, wherein a cleaning mechanism 900 is provided in each group of outlets 609, and the cleaning mechanism 900 includes a disc 901 arranged in the outlet 609, a connecting rod 902 fixed on the disc 901, and a hinge seat 903 fixed on the wrapping shell 608, the other end of the connecting rod 902 is rotatably connected to the hinge seat 903 through the shaft rod 904, and a second torsion spring 905 is provided at both ends of the shaft rod 904, one end of the second torsion spring 905 is fixed on the connecting rod 902, and the other end is fixed in the hinge seat 903, providing a reset elastic force for the disc 901, and a rubber scraper 906 is fixed to the circumferential edge of the disc 901, and the outer edge of the rubber scraper 906 fits the inner wall edge of the outlet 609, which can effectively remove residues attached to the inner wall of the outlet 609.

[0032] Specifically, in the centrifugal jet mode, when the high-pressure water flows through the flow channel 605 of the centrifugal disc 604 and is accelerated, it is ejected at high speed from the outlet 609 of the enclosing shell 608. The strong impact force generated by the high-speed water flow acts on the surface of the disc 901, causing the disc 901 to overcome the elastic force of the second torsion spring 905 and swing outward around the shaft 904 to a certain angle. At this time, the rubber scraper 906 swings along with the swing of the disc 901, close to the inner wall of the outlet 609, thereby scraping off the residue attached to the inner wall of the outlet 609.

[0033] The present invention provides a cabin cleaning device based on a stainless steel chemical tanker, the working principle of which is as follows: when working, the robot body 100 is placed in the cabin, and the external pump provides high-pressure water through the high-pressure water pipe 200. In the initial state, the through hole 607 of the adjustment disk 606 is connected to the first channel 6021, and the second channel 6022 is closed. The high-pressure water passes through the through hole 607, the first channel 6021 and the flow port 603 in sequence, and is sprayed out by the front nozzle 500 in a conventional direct injection mode to perform daily cleaning on most areas of the cabin. When encountering stubborn stains such as the high-viscosity chemical adhesion layer on the bottom of the cabin, the operator increases the water pressure of the external pump, and the high-pressure water flows into the connecting pipe 400. The increased water pressure causes the water to flow in Dynamic pressure is formed on the surface of the friction disk 801, pushing the friction disk 801 to overcome the elastic force of the spring 804 and move along the extension rod 802, thereby releasing the friction with the impeller 701. At this time, the impeller 701 rotates smoothly. While the impeller 701 rotates, the rotating shaft 702 and the connecting frame 703 drive the adjusting disk 606 to rotate, overcoming the elastic force of the first torsion spring 705. When the adjusting disk 606 rotates until the through hole 607 is connected to the second channel 6022, the first channel 6021 is closed, and high-pressure water enters the arc-shaped flow channel 605 of the centrifugal disk 604 through the second channel 6022. Due to the arc-shaped structure of the flow channel 605, the water flow generates centrifugal force, forming a high-speed rotating centrifugal jet that is ejected from the outlet 609 of the encapsulating shell 608.

[0034] During this process, high-speed water flow impacts the disc 901 of the cleaning mechanism 900, causing it to overcome the elastic force of the second torsion spring 905 and swing around the shaft 904. The rubber scraper 906 clings to the inner wall of the outlet 609 to scrape off residues. When the water pressure decreases, the first torsion spring 705 drives the adjustment disc 606 to reset and restore the direct injection mode. The spring 804 pushes the friction disc 801 to reset, increasing the friction with the impeller 701 to stop it. The second torsion spring 905 drives the disc 901 to reset and shield the inner wall of the outlet 609.
