Description

Technical Field

[0001] This invention relates to the field of deck coating technology, and more particularly to a surface treatment device for deck coating substrate materials. Background Technology

[0002] Ship decks are subject to frequent personnel movement and equipment handling, and are often in direct contact with seawater and exposed to direct sunlight, making them prone to localized wear. Therefore, to ensure the corrosion resistance, anti-slip properties, high-temperature resistance, and other performance characteristics of ship decks, staff need to inspect the deck surface at regular intervals and apply localized spraying to severely worn areas. Before localized spraying, the old coating on the worn areas must be removed, followed by the removal of oil and rust from the deck surface, and finally, the spraying process can begin.

[0003] If the old coating on the deck is removed directly with metal tools, it can easily cause great damage to the deck itself. Therefore, in order to avoid major damage to the deck as much as possible, the existing technology usually sprays a certain amount of paint remover on the processing area before removing the old coating. This can effectively reduce the damage to the deck during the removal process. However, since the paint remover is highly corrosive, it is impossible to accurately control the spraying range when spraying manually. Obviously, this will not only damage the deck coating outside the processing area, but also easily cause injury to the hands of the workers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a surface treatment device for deck coating substrate materials. It solves the technical problem in existing technologies where the spraying range cannot be precisely controlled when spraying paint remover, which can easily cause significant damage to the coating outside the processing area and the hands of workers. The device has the advantage of automatically and evenly spraying the paint remover inside the storage cylinder onto the surface of the deck coating without causing damage to the coating outside the processing area or the hands of workers.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a surface treatment device for deck coating substrate material, comprising a movable housing, a top end cap detachably installed on the upper end of the movable housing, drive wheels on both the front and rear sides of the movable housing, a fixed inclined plate fixedly installed on the right side of the movable housing, a control component installed on the upper end of the fixed inclined plate, a residual paint softening mechanism for softening deck paint inside the movable housing, a containment and shielding mechanism movably installed at the lower end of the movable housing, and a rotary scraping mechanism for scraping off deck paint at the lower end of the residual paint softening mechanism. When workers use this device to clean residual deck paint, firstly, the residual paint softening mechanism sprays paint remover onto the surface of the deck coating, and then the rotary scraping mechanism scrapes off the softened residual paint. During the process, the containment and shielding mechanism... The blocking mechanism will shield the area to be sprayed. The residual paint softening mechanism includes a circular groove at the lower end of the inner cavity of the movable housing. The lower end of the circular groove is rotatably connected to a movable circular tube. The lower end of the movable circular tube is provided with a draining component. A drive motor is fixedly installed inside the movable housing. A transmission component is provided between the output end of the drive motor and the movable circular tube. A rubber gasket is provided inside the circular groove. A liquid storage cylinder is detachably installed on the upper end of the rubber gasket. The upper end of the movable circular tube extends into the interior of the liquid storage cylinder and is fixedly installed with a fixed straight plate. A stirring component is detachably installed on the upper end of the fixed straight plate. When the movable circular tube rotates under the action of the drive motor, it will cause the draining component to rotate synchronously. When the draining component rotates, it will spray the paint remover inside the liquid storage cylinder onto the surface of the deck coating, thereby completing the softening of the old paint.

[0006] Preferably, the drainage assembly includes a drainage box detachably installed at the lower end of the movable circular tube. A control valve is provided inside the movable circular tube, and adjustable-length straight leakage pipes are symmetrically installed outside the drainage box. When the control valve is turned on, the paint remover inside the storage cylinder will be discharged outward through the drainage box and the straight leakage pipes.

[0007] Preferably, the transmission assembly includes a drive pulley that is connected to the drive motor, an external transmission connection at the upper end of the movable tube to a driven pulley, and a transmission belt between the drive pulley and the driven pulley. When the drive motor is powered on, it will cause the movable tube and the drainage assembly to rotate synchronously through the cooperation of the transmission belt.

[0008] Preferably, the stirring assembly includes a vertically mounted vertical rod on a fixed straight plate, and multiple sets of plastic crossbars are evenly spaced on the outside of the vertical rod. When the fixed straight plate rotates synchronously with the movable round tube, the vertical rod and the multiple plastic crossbars will rotate synchronously, thereby completing the mixing and stirring of the paint storage agent.

[0009] Preferably, the enclosure and shielding mechanism includes a first circular groove and a second circular groove formed at the lower end of the movable housing. An elastic airbag is fixedly installed inside both the first and second circular grooves. A sealing ring is provided at the lower end of the elastic airbag, and a straight air guide pipe is fixedly connected to the upper end of the elastic airbag. A small air pump is fixedly installed inside the movable housing. An electromagnetic valve is provided between the small air pump and the straight air guide pipe. Initially, the elastic airbag is in a contracted state. When the small air pump is working, it will inflate the elastic airbag through the electromagnetic valve. After inflation, the elastic airbag will extend downwards, thereby shielding the outside of the processing area.

[0010] Preferably, the solenoid valve is provided with an air inlet and two air outlets. The air inlet is connected to a small air pump, and the two air outlets are respectively connected to two straight air guide pipes. When the air inlet is connected to the straight air guide pipe installed at the upper end of the first circular groove, the elastic airbag installed inside the first circular groove extends downward. When the air inlet is connected to the straight air guide pipe installed at the upper end of the second circular groove, the elastic airbag installed inside the second circular groove extends downward.

[0011] Preferably, the length of the drain pipe when it is contracted is less than the inner diameter of the first circular groove, and the length of the drain pipe when it is extended is less than the inner diameter of the second circular groove. If the area to be sprayed is small, the drain pipe only needs to maintain its original length. If the area to be sprayed is large, the staff can extend the length of the drain pipe as needed.

[0012] Preferably, the rotary scraping mechanism includes a small motor fixedly installed at the lower end of the drain box. The output end of the small motor is connected to a horizontal scraper. A telescopic scraper is movably installed at the end of the horizontal scraper. A return spring is fixedly connected between the telescopic scraper and the horizontal scraper. An exhaust hole is opened at the lower end of the movable housing. A hot air fan is fixedly installed inside the movable housing. The air outlet of the hot air fan is connected to the exhaust hole. When the hot air fan is running, it blows hot air downward through the exhaust hole, thereby drying the paint remover sprayed on the ground.

[0013] By means of the above technical solution, the present invention provides a surface treatment device for deck coating substrate materials, which has at least the following beneficial effects:

[0014] 1. This invention, by setting up a residual paint softening mechanism, utilizes the cooperation between the leakage straight pipe and the movable round pipe to automatically and evenly spray the paint remover inside the storage cylinder onto the surface of the deck coating, thereby completing the softening operation of the damaged coating. It eliminates the need for manual application by workers, ensuring the uniformity of paint remover application and effectively avoiding damage to workers' hands caused by highly corrosive paint remover.

[0015] 2. By setting up a residual paint softening mechanism, the present invention utilizes the cooperation between the movable round tube, the fixed straight plate and the stirring component to automatically stir and mix the paint remover inside the storage cylinder during the spraying process. This ensures that the paint remover can flow smoothly downwards and prevents the solute inside the paint remover from precipitating.

[0016] 3. By setting up an enclosure and shielding mechanism, the present invention can automatically shield the processing area by using the cooperation between the elastic airbag and the sealing ring, thereby preventing the paint remover from flowing outside the processing area and damaging the coating of other parts. At the same time, it can also effectively prevent paint fragments generated during the scraping operation from splashing everywhere, making it easy to clean.

[0017] 4. By setting up an enclosure and shielding mechanism, the present invention utilizes the cooperation between the first and second circular grooves to help workers freely adjust the enclosure area according to actual needs, which can effectively reduce the area of ​​coating damaged due to local spraying.

[0018] 5. This invention, by setting up a rotating scraping mechanism, utilizes the cooperation between a horizontal scraper, a telescopic scraper, and a hot air blower to automatically scrape and clean the softened deck coating, thereby completing the removal of the old coating. Moreover, during the cleaning process, hot air can be automatically blown into the enclosed area to accelerate the drying rate of the paint remover and prevent a small amount of paint remover from flowing to other parts of the deck and causing damage to the deck after the elastic airbag contracts.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] according to Figures 1-6 As shown, a surface treatment device for a deck coating substrate material includes a movable housing 1. A top end cap 2 is detachably installed on the upper end of the movable housing 1. Drive wheels 3 are provided on both the front and rear sides of the movable housing 1. A fixed inclined plate 4 is fixedly installed on the right side of the movable housing 1. A control component 5 is provided on the upper end of the fixed inclined plate 4. The interior of the movable housing 1 is provided with a residual paint softening mechanism 6 for softening deck paint. An enclosure and shielding mechanism 7 is movably installed on the lower end of the movable housing 1. A rotary scraping mechanism 8 for scraping off deck paint is provided at the lower end of the residual paint softening mechanism 6. When the operator uses this device to clean the residual paint on the deck, firstly, the residual paint softening mechanism 6 sprays paint remover onto the surface of the deck coating. Next, the rotary scraping mechanism 8 scrapes off the softened residual paint. During the process, the enclosure and shielding mechanism 7 shields the area to be sprayed.

[0032] Specifically, the residual paint softening mechanism 6 includes a circular groove 601 formed at the lower end of the inner cavity of the movable housing 1. A movable circular tube 602 is rotatably connected to the lower end of the circular groove 601. A drainage assembly 603 is provided at the lower end of the movable circular tube 602. A drive motor 604 is fixedly installed inside the movable housing 1. A transmission assembly 605 is provided between the output end of the drive motor 604 and the movable circular tube 602. A rubber gasket 606 is provided inside the circular groove 601. The upper end is detachably equipped with a liquid storage cylinder 607. The upper end of the movable cylindrical tube 602 extends into the interior of the liquid storage cylinder 607 and is fixedly equipped with a fixing plate 608. The upper end of the fixing plate 608 is detachably equipped with a stirring component 609. When the movable cylindrical tube 602 rotates under the action of the drive motor 604, it will cause the drain component 603 to rotate synchronously. When the drain component 603 rotates, it will spray the paint remover inside the liquid storage cylinder 607 onto the surface of the deck coating, thereby completing the softening of the old paint.

[0033] More specifically, the drainage assembly 603 includes a drainage box that is detachably installed at the lower end of the movable circular tube 602. The movable circular tube 602 is equipped with a control valve inside. The drainage box is symmetrically equipped with adjustable-length straight drain pipes. When the control valve is turned on, the paint remover inside the storage cylinder 607 will be discharged outward through the drainage box and the straight drain pipes.

[0034] More specifically, the transmission assembly 605 includes a drive pulley that is connected to the drive motor 604, an external transmission connection at the upper end of the movable tube 602 to the driven pulley, and a transmission belt between the drive pulley and the driven pulley. When the drive motor 604 is energized, it will cause the movable tube 602 and the drainage assembly 603 to rotate synchronously through the cooperation of the transmission belt.

[0035] More specifically, the mixing assembly 609 includes a vertically mounted vertical rod on a fixed straight plate 608. Multiple sets of plastic crossbars are evenly spaced on the outside of the vertical rod. When the fixed straight plate 608 rotates synchronously with the movable round tube 602, the vertical rod and the multiple plastic crossbars will rotate synchronously, thereby completing the mixing and stirring of the paint storage agent.

[0036] In this embodiment, when in use, the operator will use the control component 5 to control the rotation of the drive wheel 3. When the drive wheel 3 rotates, it will cause the movable housing 1 to move horizontally on the deck, thereby moving the device above the part of the deck to be sprayed.

[0037] Next, the movable circular tube 602 will rotate at a certain speed with the cooperation of the transmission component 605 and the drive motor 604. When the movable circular tube 602 rotates, the leakage straight tube will rotate synchronously. At the same time, the liquid control valve inside the movable circular tube 602 will be automatically turned on. After the liquid control valve is turned on, the paint remover inside the liquid storage cylinder 607 will be sprayed downward through the movable circular tube 602 and the leakage straight tube, thereby spraying the paint remover onto the surface of the deck coating and completing the softening of the deck coating.

[0038] Moreover, such as Figure 6 As shown, when the movable circular tube 602 rotates, the fixed straight plate 608 will rotate synchronously. When the fixed straight plate 608 rotates, the vertical circular rod and the plastic horizontal rod will rotate synchronously. During the rotation of the vertical circular rod and the plastic horizontal rod, the paint remover inside the liquid storage cylinder 607 will be stirred and mixed, thereby preventing the solute inside the paint remover from precipitating.

[0039] This embodiment, by setting up a residual paint softening mechanism 6, utilizes the cooperation between the straight drain pipe and the movable circular pipe 602 to automatically and evenly spray the paint remover inside the storage cylinder 607 onto the surface of the deck coating, thereby completing the softening operation of the damaged coating. This eliminates the need for manual application by workers, ensuring the uniformity of the paint remover application and effectively preventing damage to workers' hands from the highly corrosive paint remover. Furthermore, by setting up the residual paint softening mechanism 6, and utilizing the cooperation between the movable circular pipe 602, the fixed straight plate 608, and the stirring assembly 609, this embodiment can automatically stir and mix the paint remover inside the storage cylinder 607 during the spraying process. This ensures that the paint remover flows smoothly downwards and prevents the precipitation of solutes within the paint remover.

[0040] Example 2

[0041] according to Figures 2-5 , Figure 7 as well as Figure 8As shown, based on Embodiment 1, the enclosure and shielding mechanism 7 includes a first circular groove 701 and a second circular groove 702 formed at the lower end of the movable housing 1. The length of the leakage straight pipe when it is contracted is less than the inner diameter of the first circular groove 701, and the length of the leakage straight pipe when it is extended is less than the inner diameter of the second circular groove 702. If the area to be sprayed is small, the leakage straight pipe only needs to maintain its original length. If the area to be sprayed is large, the operator can extend the length of the leakage straight pipe as needed. Elastic airbags 703 are fixedly installed inside both the first circular groove 701 and the second circular groove 702. A sealing ring 704 is provided at the lower end of the elastic airbag 703, and a guide pipe 7 is fixedly connected to the upper end of the elastic airbag 703. 05. A small air pump 707 is fixedly installed inside the movable housing 1. An electromagnetic valve 706 is provided between the small air pump 707 and the air guide pipe 705. The electromagnetic valve 706 is provided with one air inlet and two air outlets. The air inlet is connected to the small air pump 707, and the two air outlets are respectively connected to the two air guide pipes 705. Initially, the elastic airbag 703 is in a contracted state. When the air inlet is connected to the air guide pipe 705 installed at the upper end of the first circular groove 701, the elastic airbag 703 installed inside the first circular groove 701 extends downward. When the air inlet is connected to the air guide pipe 705 installed at the upper end of the second circular groove 702, the elastic airbag 703 installed inside the second circular groove 702 extends downward.

[0042] In this embodiment, before the paint remover spraying operation begins, the worker will first adjust the length of the leakage straight pipe according to the area of ​​the processing area. After the length adjustment is completed, if the length of the leakage straight pipe is less than the diameter of the first circular groove 701, then the air inlet of the solenoid valve 706 will be connected to the air outlet at the upper end of the first circular groove 701. Next, the small air pump 707 will inflate the interior of the elastic airbag 703 through the solenoid valve 706, so that the elastic airbag 703 extends vertically downward and surrounds the outside of the processing area. Moreover, after the elastic airbag 703 extends downward, it will make the sealing ring 704 fit tightly against the surface of the deck.

[0043] If the adjusted length of the leakage straight pipe is greater than the diameter of the first circular groove 701 but less than the diameter of the second circular groove 702, then the air inlet of the solenoid valve 706 will connect with the air outlet at the upper end of the second circular groove 702. Next, the elastic airbag 703 inside the second circular groove 702 will extend downward under the action of the small air pump 707, thereby enclosing the outside of the processing area.

[0044] This embodiment, by setting up an enclosure and shielding mechanism 7, utilizes the cooperation between the elastic airbag 703 and the sealing ring 704 to automatically shield the processing area, thereby preventing paint remover from flowing outside the processing area and damaging the coating on other parts. It also effectively prevents paint fragments generated during the scraping operation from splashing everywhere, making it easier to clean. In addition, by setting up an enclosure and shielding mechanism 7, this embodiment, through the cooperation between the first circular groove 701 and the second circular groove 702, can help the operator freely adjust the enclosure area according to actual needs, which can effectively reduce the area of ​​coating damaged due to local spraying processing.

[0045] Example 3

[0046] according to Figure 2 and Figure 8 As shown, based on the above embodiment, the rotary scraping mechanism 8 includes a small motor 801 fixedly installed at the lower end of the drain box. The output end of the small motor 801 is connected to a horizontal scraper 802. A telescopic scraper 803 is movably installed at the end of the horizontal scraper 802. A return spring is fixedly connected between the telescopic scraper 803 and the horizontal scraper 802. An exhaust hole 804 is opened at the lower end of the movable housing 1. A hot air fan 805 is fixedly installed inside the movable housing 1. The air outlet of the hot air fan 805 is connected to the exhaust hole 804. When the hot air fan 805 is running, it blows hot air downward through the exhaust hole 804, thereby drying the paint remover sprayed on the ground.

[0047] In this embodiment, after the paint remover is sprayed for a certain period of time, the horizontal scraper 802 will rotate under the action of the small motor 801. Since the horizontal scraper 802 is in contact with the surface of the deck coating, the horizontal scraper 802 can scrape off the softened and bulging coating when it rotates, thereby completing the removal process of the deck surface coating.

[0048] Moreover, if the area of ​​coating to be cleaned is large, the staff only needs to increase the output power of the small motor 801 to increase the rotation speed of the horizontal scraper 802. When the horizontal scraper 802 rotates more, the telescopic scraper 803 will extend outward under the action of centrifugal force, thereby increasing the scraping area.

[0049] In addition, during the scraping and cleaning process, the hot air blower 805 will blow hot air into the enclosed area through the exhaust hole 804, thereby accelerating the evaporation and drying rate of the paint remover and preventing a small amount of paint remover from flowing to other parts of the deck after the elastic airbag 703 contracts.

[0050] This embodiment, by setting up a rotating scraping mechanism 8, utilizes the cooperation between the horizontal scraper 802, the telescopic scraper 803, and the hot air blower 805 to automatically scrape and clean the softened deck coating, thereby completing the removal of the old coating. Moreover, during the cleaning process, hot air can be automatically blown into the enclosed area to accelerate the drying rate of the paint remover and prevent a small amount of paint remover from flowing to other parts of the deck and causing damage to the deck after the elastic airbag 703 contracts.

[0051] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
