Description

Technical Field

[0001] This disclosure relates to the technical field of building environmental protection maintenance, and in particular to a transport AGV robot and spraying equipment for building anti-corrosion paint. Background Technology

[0002] Currently, many industrial buildings, such as chemical tanks, oil storage tanks, and reaction vessels, have metal exterior walls, and many of these buildings are exposed to the elements, making their exterior walls highly susceptible to corrosion. The resulting corrosion waste easily pollutes the environment. To address these issues, most manufacturers use automated wall painting robots, such as those disclosed in Chinese patent document CN106088544B, to apply anti-corrosion paint to the exterior walls of industrial buildings. However, because industrial buildings typically have large exterior wall areas, these robots need to move over a wide area to spray paint. The limitations of the robot's load-bearing capacity and paint tank volume mean the anti-corrosion paint is quickly depleted, requiring frequent opening of the paint tank for replenishment. Furthermore, the anti-corrosion paint hardens upon contact with air during the paint tank replenishment process, reducing its effectiveness on the industrial building's exterior walls. Utility Model Content

[0008] The AGV robot for transporting building anti-corrosion paint also includes a stirring fluidization component and a slow-flow feeding component.

[0009] The slow-flow feeding assembly includes an end cap and a buffer paint guide tube; both the stirring fluidization assembly and the buffer paint guide tube are installed at the top of the paint storage tank; the top of the buffer paint guide tube extends outside the paint storage tank and forms a paint inlet; the end cap is detachably installed on the buffer paint guide tube and seals the paint inlet; the stirring impeller of the stirring fluidization assembly is rotatably disposed inside the paint storage tank and is located below the lowest liquid level line of the anti-corrosion paint; the bottom end of the buffer paint guide tube extends obliquely towards the stirring impeller and forms a paint feeding port above the stirring impeller; the paint feeding port communicates with the interior of the paint storage tank and is used to discharge the anti-corrosion paint to the stirring impeller.

[0010] In some embodiments, the bottom end of the buffer paint guide tube forms a conical structure, with the tip of the conical structure facing the stirring paddle; the paint feeding port is located at the tip of the conical structure.

[0011] In some embodiments, the inner diameter of the bottom portion of the buffer paint guide tube gradually increases from the paint feeding port to the paint dispensing port; and / or,

[0012] The inner diameter of the middle part of the buffer paint guide tube is equal to the inner diameter of the paint inlet.

[0013] In some embodiments, a pressure-stabilizing vent is provided on the peripheral wall of the buffer paint guide tube; the pressure-stabilizing vent is located inside the paint storage tank and is disposed away from the paint feeding port; the interior of the paint storage tank is connected to the interior of the buffer paint guide tube through the pressure-stabilizing vent.

[0014] In some embodiments, the paint inlet is located below the lowest liquid level line of the anti-corrosion paint.

[0015] In some embodiments, the AGV robot for handling architectural anti-corrosion paint further includes an ultrasonic level sensor, which is installed at the top of the paint storage tank; the detection end of the ultrasonic level sensor faces the bottom of the paint storage tank and is used to measure the liquid level of the anti-corrosion paint in the paint storage tank.

[0016] In some embodiments, the AGV robot for transporting anti-corrosion paint further includes a liquid level alarm; the liquid level alarm is installed on the AGV and electrically connected to the ultrasonic liquid level sensor.

[0017] In some embodiments, the AGV robot for transporting architectural anti-corrosion paint further includes an oxygen desiccation and gas replenishment device; the oxygen desiccation and gas replenishment device is installed on the top of the paint storage tank, and the interior of the paint storage tank is connected to the outside through the oxygen desiccation and gas replenishment device.

The paint level in the tank remains consistently above this minimum level, ensuring the agitator remains within the paint. Furthermore, the top of the buffer guide tube extends outside the tank, forming a paint inlet, while the bottom of the tube extends towards the agitator, forming a feeding port. When the anti-corrosion paint level approaches the minimum level, a predetermined amount of paint can be rapidly dispensed from the inlet into the buffer guide tube. The inlet is then quickly sealed with an end cap to minimize air contact with the paint. Under gravity, the paint is discharged through the feeding port to the agitator, increasing the fluidity of the newly dispensed paint under the agitation of the agitator. This reduces curing and improves the coating effect on the exterior walls of industrial buildings. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0040] Please see Figure 1 and Figure 2 An embodiment of an AGV robot for transporting architectural anti-corrosion paint includes a paint storage tank 100, an AGV transport vehicle 200, a mixing fluidization assembly 300, and a slow-flow feeding assembly 400. The paint storage tank 100 is used to store anti-corrosion paint. The AGV transport vehicle 200 is installed at the bottom of the paint storage tank 100 and is used to transport the paint storage tank 100. The slow-flow feeding assembly 400 includes an end cap 410 and a buffer paint guide tube 420. The mixing fluidization assembly 300 and the buffer paint guide tube 420 are both installed at the top of the paint storage tank 100. The buffer paint guide tube 420... The top extends to the outside of the paint storage tank 100 and forms a paint inlet 401; the end cap 410 is detachably installed on the buffer paint guide tube 420 and seals the paint inlet 401; the stirring paddle 330 of the stirring fluidization assembly 300 is rotatably disposed inside the paint storage tank 100 and is located below the lowest liquid level line 101 of the anti-corrosion paint; the bottom end of the buffer paint guide tube 420 extends obliquely toward the stirring paddle 330 and forms a paint feeding port 402 above the stirring paddle 330; the paint feeding port 402 is connected to the inside of the paint storage tank 100 and is used to discharge anti-corrosion paint to the stirring paddle 330.

[0041] It is understandable that, since the agitator 330 of the stirring fluidization component 300 is rotatably disposed inside the paint storage tank 100 and located below the lowest liquid level line 101 of the anti-corrosion paint, the liquid level of the anti-corrosion paint in the paint storage tank 100 is always above the lowest liquid level line 101 of the anti-corrosion paint, allowing the agitator 330 to remain within the anti-corrosion paint. Furthermore, since the top of the buffer guide tube 420 extends outside the paint storage tank 100 to form a paint inlet 401, and the bottom of the buffer guide tube 420 extends inclined towards the agitator 330 to form a paint feeding inlet 402, when the liquid level of the anti-corrosion paint approaches... When the anti-corrosion paint reaches the lowest liquid level 101, a predetermined amount of anti-corrosion paint can be quickly added into the buffer paint guide cylinder 420 from the paint inlet 401 in one go. Then, the paint inlet 401 is quickly sealed by the end cap 410 to reduce the contact between air and anti-corrosion paint. Under the action of gravity, the anti-corrosion paint is discharged into the agitator 330 through the paint feeding port 402, so that the newly added anti-corrosion paint can increase its fluidity under the agitation action of the agitator 330, thereby reducing the curing of the anti-corrosion paint and improving the coating effect of the anti-corrosion paint on the exterior wall of industrial buildings.

[0042] Please see Figure 2 In some embodiments, the bottom end of the buffer paint guide tube 420 forms a conical structure, with the tip of the conical structure facing the agitator 330; the paint feeding port 402 is located at the tip of the conical structure. It can be understood that because the tip of the conical structure faces the agitator 330 and the paint feeding port 402 is located at the tip, the anti-corrosion paint inside the buffer paint guide tube 420 can be slowly discharged into the agitator 330 through the paint feeding port 402, thereby better increasing the flowability of the newly added anti-corrosion paint through the agitator 330.

[0043] Please see Figure 2 In some embodiments, the inner diameter of the bottom portion of the buffer paint guide tube 420 gradually increases from the paint feeding port 402 to the paint dispensing port 401. It can be understood that because the inner diameter of the bottom portion of the buffer paint guide tube 420 gradually increases from the paint feeding port 402 to the paint dispensing port 401, i.e., the inner diameter of the paint feeding port 402 gradually decreases, the anti-corrosion paint can be slowly discharged into the agitator 330 through the paint feeding port 402.

[0044] Please see Figure 2 In some embodiments, the inner diameter of the middle portion of the buffer paint guide tube 420 is equal to the inner diameter of the paint inlet 401. It can be understood that since the inner diameter of the middle portion of the buffer paint guide tube 420 is equal to the inner diameter of the paint inlet 401, that is, the inner diameter of the paint inlet 401 is consistent with the inner diameter of the portion of the buffer paint guide tube 420 near the top, it ensures that the anti-corrosion paint added into the buffer paint guide tube 420 from the paint inlet 401 can quickly enter the middle portion of the buffer paint guide tube 420, thereby improving the efficiency of anti-corrosion paint dispensing and ultimately reducing the contact time between the newly dispensed anti-corrosion paint and air.

[0045] Please see Figure 2 and Figure 3 In some embodiments, a pressure-stabilizing vent 403 is provided on the peripheral wall of the buffer paint guide cylinder 420. The pressure-stabilizing vent 403 is located inside the paint storage tank 100 and is positioned away from the paint feeding port 402. The interior of the paint storage tank 100 is connected to the interior of the buffer paint guide cylinder 420 through the pressure-stabilizing vent 403. It can be understood that when anti-corrosion paint is added to the buffer paint guide cylinder 420, the gas inside the paint storage tank 100 can enter the buffer paint guide cylinder 420 through the pressure-stabilizing vent 403 and be discharged. Thus, the newly added anti-corrosion paint can smoothly enter the interior of the paint storage tank 100 through the paint feeding port 402 under the influence of gravity. Specifically, the pressure-stabilizing vent 403 is a one-way vent, and the gas inside the paint storage tank 100 can only enter the buffer paint guide cylinder 420 through the pressure-stabilizing vent 403.

[0046] Please see Figure 2 In some embodiments, the paint feeding port 402 is located below the lowest liquid level line 101 of the anti-corrosion paint. It is understood that because the paint feeding port 402 is located below the lowest liquid level line 101 of the anti-corrosion paint, the paint feeding port 402 remains submerged within the anti-corrosion paint. When the end cap 410 is opened to the paint inlet 401, the anti-corrosion paint can liquid-seal the paint feeding port 402, thereby reducing the amount of air entering the oxidizing and curing anti-corrosion paint from the paint feeding port 402.

[0047] Please see Figure 1 and Figure 2 In some embodiments, the AGV robot for handling architectural anti-corrosion paint also includes an ultrasonic level sensor 500, which is installed at the top of the paint storage tank 100. The detection end of the ultrasonic level sensor 500 faces the bottom of the paint storage tank 100 and is used to measure the liquid level of the anti-corrosion paint inside the paint storage tank 100. It is understood that because the detection end of the ultrasonic level sensor 500 installed at the top of the paint storage tank 100 faces the bottom of the paint storage tank 100, the ultrasonic level sensor 500 can measure the liquid level of the anti-corrosion paint inside the paint storage tank 100 in real time, thereby reducing the occurrence of the liquid level of the anti-corrosion paint inside the paint storage tank 100 falling below the minimum liquid level line 101 of the anti-corrosion paint.

[0048] Please see Figure 1 and Figure 2In some embodiments, the AGV robot for transporting anti-corrosion paint also includes a liquid level alarm 600; the liquid level alarm 600 is installed on the AGV transport vehicle 200 and electrically connected to the ultrasonic liquid level sensor 500. It is understood that the minimum liquid level line 101 of the anti-corrosion paint is the liquid level height of the paint storage tank 100 in a safe operating state, for example, 25cm, at which point the paint storage tank 100 is not in an empty state. Since the liquid level alarm 600 is electrically connected to the ultrasonic liquid level sensor 500, when the liquid level of the anti-corrosion paint in the paint storage tank 100 is lower than the minimum liquid level line 101, the ultrasonic liquid level sensor 500 controls the liquid level alarm 600 to issue an alarm, thus timely reminding the staff to replenish the anti-corrosion paint in the paint storage tank 100. It should be specifically noted that the method of the ultrasonic liquid level sensor 500 controlling the liquid level alarm 600 to issue an alarm is prior art and not within the scope of protection of this disclosure, therefore it will not be described in detail here.

[0049] Please see Figure 1 and Figure 4 In some embodiments, the AGV robot for handling architectural anti-corrosion paint also includes an oxygen desiccant and gas replenishment device 700. The oxygen desiccant and gas replenishment device 700 is installed at the top of the paint storage tank 100, and the interior of the paint storage tank 100 is connected to the outside through the oxygen desiccant and gas replenishment device 700. It can be understood that because the interior of the paint storage tank 100 is connected to the outside through the oxygen desiccant and gas replenishment device 700, when the level of the anti-corrosion paint in the paint storage tank 100 drops due to use, outside air can enter the interior of the paint storage tank 100 through the oxygen desiccant and gas replenishment device 700. The oxygen desiccant and gas replenishment device 700 removes oxygen from the air, preventing the gas entering the paint storage tank 100 from oxidizing and solidifying the anti-corrosion paint. Simultaneously, the gas can balance the air pressure inside and outside the paint storage tank 100, allowing the anti-corrosion paint to be sprayed out smoothly for use. Specifically, the deoxygenation and gas replenishment device 700 includes a housing 710 and an oxygen absorbent 720. The housing 710 is installed at the top of the paint storage tank 100, the oxygen absorbent 720 is disposed inside the housing 710, an air inlet 701 is opened on the outer periphery of the housing 710, and the air outlet of the housing 710 is connected to the interior of the paint storage tank 100. The oxygen absorbent 720 is sodium dithionite powder, etc.

[0050] Please see Figure 2 and Figure 3 In some embodiments, the end cap 410 is snapped or screwed onto the buffer paint guide tube 420, and the edge of the end cap 410 engages with the edge of the paint inlet 401 via a sealing ring 411.

[0051] Please see Figure 2 and Figure 5In some embodiments, the stirring fluidization assembly 300 includes a rotary driver 310, a drive shaft 320, and a stirring paddle 330. The rotary driver 310 is fixedly installed on the outer side of the top of the paint storage tank 100. The first end of the drive shaft 320 is connected to the power output end of the rotary driver 310, and the second end of the drive shaft 320 passes through the rotating hole 102 of the paint storage tank 100 and is fixedly connected to the stirring paddle 330. The shaft wall of the drive shaft 320 is rotatably connected to the hole wall of the rotating hole 102. It can be understood that since the power output end of the rotary driver 310, which is fixedly installed on the outer side of the top of the paint storage tank 100, is fixedly connected to the stirring paddle 330 through the drive shaft 320, and the second end of the drive shaft 320 passes through the rotating hole 102 of the paint storage tank 100, and the shaft wall of the drive shaft 320 is rotatably connected to the hole wall of the rotating hole 102, the stirring paddle 330 can rotate inside the paint storage tank 100 under the drive of the rotary driver 310. A sealed bearing 1021 is fitted on the shaft wall of the transmission shaft 320. The inner ring of the sealed bearing 1021 is fixedly connected to the shaft wall of the transmission shaft 320, and the outer ring of the sealed bearing 1021 is fixedly connected to the hole wall of the rotating hole 102.

[0052] Please see Figures 1 to 5 This disclosure also provides a painting device, including a paint spray gun (not shown) and a AGV robot for transporting architectural anti-corrosion paint according to any of the above embodiments; the paint inlet of the paint spray gun is connected to the interior of the paint storage tank 100. It can be understood that by applying the AGV robot for transporting architectural anti-corrosion paint of this disclosure to the painting device, since the agitator 330 of the stirring fluidization component 300 is rotatably disposed inside the paint storage tank 100 and located below the lowest liquid level line 101 of the anti-corrosion paint, the liquid level of the anti-corrosion paint in the paint storage tank 100 is always above the lowest liquid level line 101 of the anti-corrosion paint, allowing the agitator 330 to remain within the anti-corrosion paint. Furthermore, since the top end of the buffer guide tube 420 extends outside the paint storage tank 100 and forms a paint inlet 401, and the bottom end of the buffer guide tube 420 extends obliquely towards the agitator 330 to form a feeding port... When the level of the anti-corrosion paint approaches the minimum level line 101, a predetermined amount of anti-corrosion paint can be quickly added from the inlet 402 into the buffer paint guide cylinder 420. The inlet 401 is then quickly sealed by the end cap 410 to reduce air contact with the anti-corrosion paint. Under gravity, the anti-corrosion paint is discharged through the feed inlet 402 into the agitator 330, increasing the fluidity of the newly added anti-corrosion paint under the agitation of the agitator 330. This reduces curing and improves the coating effect on the exterior walls of industrial buildings. Simultaneously, since the paint inlet of the paint spray gun is connected to the interior of the paint storage tank 100, the anti-corrosion paint inside the tank 100 can be applied to the exterior walls of industrial buildings via the paint spray gun.

[0053] Compared with the prior art, this disclosure has at least the following advantages:

[0054] In the aforementioned AGV robot for handling anti-corrosion paint, the agitator 330 of the mixing fluidization component 300 is rotatably positioned inside the paint storage tank 100 and located below the lowest liquid level line 101 of the anti-corrosion paint. This ensures that the liquid level of the anti-corrosion paint in the storage tank 100 is always above the lowest liquid level line 101, allowing the agitator 330 to remain within the anti-corrosion paint. Furthermore, the top of the buffer guide tube 420 extends outside the paint storage tank 100 to form a paint inlet 401, and the bottom of the buffer guide tube 420 extends inclined towards the agitator 330 to form a paint feeding inlet 402. When the anti-corrosion paint... When the paint level is close to the minimum level line 101 of the anti-corrosion paint, a predetermined amount of anti-corrosion paint can be quickly added into the buffer paint guide cylinder 420 from the paint inlet 401. Then, the paint inlet 401 is quickly sealed by the end cap 410 to reduce the contact between air and the anti-corrosion paint. Under the action of gravity, the anti-corrosion paint is discharged into the agitator 330 through the paint feeding port 402, so that the newly added anti-corrosion paint can increase its fluidity under the agitation of the agitator 330, thereby reducing the curing of the anti-corrosion paint and improving the coating effect of the anti-corrosion paint on the exterior wall of industrial buildings.

[0055] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
