Description

Technical Field

[0001] This invention relates to the field of high-end equipment manufacturing technology, specifically to a special robot for cleaning building pipes with high applicability. Background Technology

[0002] Currently, ventilation ducts in large factory buildings often accumulate severe dust due to prolonged lack of cleaning. This not only easily breeds bacteria, affecting the respiratory health of workers inside the building, but also causes excessive dust to block the ventilation ducts, hindering air circulation. Therefore, ventilation ducts must be cleaned regularly. However, traditional duct cleaning involves manual scraping of the duct walls with cleaning rods, which is not only inefficient but also fails to remove dust deep within the ducts. Furthermore, workers cleaning at heights are at risk of falling.

[0003] In the prior art, such as the Chinese patent CN 113587300 A, "A Dust Removal and Ventilation Device for Building HVAC Engineering," a main body is included, with a pipe connected to the main body, and a filter element connected to the main body; a connecting member is movably connected to the filter element, and the connecting member is provided with a first cleaning member and a second cleaning member, which are in close contact with the filter element; an exhaust fan is connected to the pipe; the exhaust fan introduces outdoor air into the pipe, and the air enters the air chamber and drives the first and second cleaning members to move upward away from the filter element through the connecting member. During the upward movement of the first and second cleaning members, the filter element that is blocked is connected to the outside, and the air filtered by the filter element enters the room. When the fan is turned off, the first and second cleaning members fall down, and the first and second cleaning members clean the filter holes on the filter element in turn. This has the advantages of preventing device blockage and having a good cleaning effect. However, in actual use, this device can only clean the inner walls of some vertically or obliquely installed ventilation ducts. It cannot effectively clean the horizontal ventilation ducts that are laid out over a large area in the building. Moreover, the dust removal device is installed on the inner wall of the duct, which not only increases the difficulty of laying the ventilation duct and increases the maintenance cost of the ventilation duct, but also causes a large amount of dust to stick to its surface when the dust removal device is installed in the ventilation duct for a long time, which will greatly affect the dust removal effect.

[0004] Therefore, a highly applicable special robot for cleaning building pipes is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The main objective of this invention is to provide a highly applicable special robot for cleaning building pipes, capable of cleaning accumulated dust deep within pipes and cleaning pipes laid over large areas within buildings.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A highly versatile special-purpose robot for cleaning building pipes includes:

[0008] The support frame is designed as a ring-shaped column structure to support the components located on it;

[0009] A cleaning component, which is installed in a ring shape at one end of a support frame, includes a ring plate and an inflatable component disposed on the ring plate. The inflatable component can change its diameter after being filled with gas. The inflatable component is used to scrape the dust accumulated in the pipe along the inner wall.

[0010] The displacement component, mounted on the support frame, is used to move the support frame and its components within the pipeline.

[0011] The dust collection assembly includes a dust collection ring and at least one dust collection bag, which is mounted on a support frame with the opening of the dust collection bag facing one side of the cleaning assembly. The dust collection ring is located at the end of the support frame away from the cleaning assembly, and the dust collection ring is in communication with the bottom of each dust collection bag.

[0012] An air pump is mounted on a support frame. The air pump's suction end is connected to the ash storage ring, and the air pump's outlet end is connected to the inflation component.

[0013] Furthermore, the ash storage ring includes a rigidly sealed annular shell and a dust collection bag disposed inside the shell. Dust from the ash storage bag enters the dust collection bag, which has a breathable filtration function. The suction end of the air pump is connected to the inner cavity of the shell, but not directly connected to the inside of the dust collection bag.

[0014] Furthermore, the support frame is equipped with an image acquisition device and a transmission device.

[0015] Furthermore, the displacement assembly includes two semicircular rings disposed on the outside of the support frame, and telescopic members disposed on the support frame corresponding to each semicircular ring. The telescopic members are used to push the corresponding semicircular rings closer to and away from the support frame.

[0016] Each semicircular ring has a traveling component on its outside, which is used to contact the inner wall of the pipe and push the displacement assembly to generate displacement.

[0017] Furthermore, the traveling component includes a main housing, at least one roller disposed within the main housing, and a motor disposed within the main housing, wherein the motor drives each roller to rotate via a transmission belt.

[0018] Furthermore, a support rod is provided inside the support frame, and a movable block is provided on the support rod. Telescopic rods are slidably installed at both ends of the movable block, and the other end of each telescopic rod is connected to a corresponding semicircular ring. The telescopic component is slidably installed on the movable block, and the telescopic component's telescopic direction is the same as the telescopic rod's sliding direction.

[0019] A stop is provided at the position between the two telescopic parts of the movable block, and an elastic element is provided between each telescopic part and the stop.

[0020] Furthermore, a wind-driven component is provided in the middle of the support frame. The wind-driven component includes multiple fan blades and is fixedly connected to the support frame. There is no rotation between the fan blades and the support frame.

[0021] Furthermore, the two ends of the semicircular ring are provided with extrusion members, the extrusion members include arc-shaped plates, which are rotatably mounted on the corresponding semicircular rings, and a torsion spring is provided at the connection position between the arc-shaped plate and the semicircular ring, so that the arc-shaped plate is in an outward opening state through the torsion spring.

[0022] Furthermore, a through-hole limiting groove is provided at the position of the corresponding ash storage bag on the semi-circular ring, the ash storage bag is placed in the corresponding limiting groove, and a tension ring is provided on the inner side of the bag opening of each ash storage bag. The tension ring is used to open the bag opening of the ash storage bag. A rotating shaft is provided on the inner side of the tension ring, and rotating plates are provided on both sides of the rotating shaft in the length direction.

[0023] Furthermore, the inflatable component includes a retaining shell, an airbag disposed within the retaining shell, and a scraper disposed on the top of the airbag. The airbag is provided with a limiting frame inside, an eccentric wheel is mounted on the limiting frame, and a blowing blade is disposed on the eccentric wheel. When the gas in the airbag flows through the blowing blade, the blowing blade drives the eccentric wheel to rotate under the blowing of the airflow, causing the inflatable component to vibrate.

[0024] The beneficial effects of this invention are reflected in:

[0025] This invention utilizes a variable-diameter inflatable component, allowing the device to enter pipes more easily. Once inside, inflation ensures the component adheres closely to the pipe's inner wall, facilitating better scraping and dust removal. The variable-diameter component also makes it suitable for use in pipes of various sizes, offering broad applicability. A displacement mechanism allows the device to move within the pipe, cleaning accumulated dust deep within. Furthermore, a single air pump can simultaneously create negative pressure on the dust collection ring and bag while inflating the component, enhancing the device's efficiency.

[0041] See Figures 1 to 9 .

[0042] like Figures 1 to 5 As shown, a highly applicable special robot for cleaning building pipes includes:

[0043] A ring-shaped support frame 1 is used to support the components located on it;

[0044] A ring-shaped cleaning component 2 is installed at one end of the support frame 1. The cleaning component 2 includes a ring plate 21 and an inflatable component 22 disposed on the ring plate 21. The diameter of the inflatable component 22 can be changed after being filled with gas. The inflatable component 22 is used to scrape the dust accumulated in the pipe along the inner wall.

[0045] Displacement component 3 is mounted on support frame 1 and is used to drive support frame 1 and the components on support frame 1 to move inside the pipeline.

[0046] The dust collection assembly includes a dust collection ring 4 and at least one dust collection bag 5, which is disposed on a support frame 1. The opening of the dust collection bag 5 faces the side of the cleaning assembly 2. The dust collection ring 4 is located at the end of the support frame 1 away from the cleaning assembly 2. The dust collection ring 4 is in communication with the bottom of each dust collection bag 5.

[0047] An air pump 6 is mounted on a support frame 1. The air pump 6 has an intake end connected to a ash storage ring 4 and an outlet end connected to an inflation component 22.

[0048] In practice, when the equipment is placed inside the pipeline and its movement direction is the same as the airflow inside the pipeline, the annular support frame 1, the ring plate 21, the air-filling component 22, and the ash-storing ring 4 ensure that the airflow channel is not blocked during the dust removal operation inside the pipeline, allowing the pipeline to continue operating normally. Furthermore, the opposing airflow within the pipeline accelerates the absorption of accumulated ash into the ash-storing bag 5. During operation, the air pump 6 and the displacement component 3 are activated. The air pump 6 draws in gas from the ash-storing ring 4, creating a negative pressure state for the ash-storing ring 4. Since the ash-storing ring 4 is connected to the bottom of each ash-storing bag 5, the ash-storing bags 5 are also under negative pressure. While drawing in air, the air pump 6 pumps gas into the air-filling component 22. After being filled with gas, the diameter of the air-filling component 22 increases, allowing for better contact with the inner wall of the pipeline. This scrapes and removes ash from the inner wall of the pipeline, and the scraped-off dust is drawn into the ash-storing bag 5 and the ash-storing ring 4.

[0049] It should be noted that, in order to prevent the gas inside the inflation component 22 from only entering and not exiting, thus damaging the inflation component 22, the inflation component 22 can be made of a non-sealed material, allowing the gas inside the inflation component 22 to escape through it, and the greater the internal air pressure of the inflation component 22, the faster the gas escapes; alternatively, a pressure relief valve 221 can be added to the inflation component 22 or to the pipeline between the inflation component 22 and the air pump 6 (e.g., Figure 1 , Figure 7 (As shown), this prevents the inflatable component 22 from being damaged, while also ensuring the internal air pressure of the inflatable component 22, thereby ensuring the scraping force inside the pipe.

[0050] In this embodiment, although the air pump 6 directly draws in the gas from the ash storage ring 4 and pumps the gas into the inflation component 22, the gas will contain some dust. However, it should be noted that the dust entering the inflation component 22 does not affect the use of this device, and the inflation component 22 can still operate normally.

[0051] This invention utilizes a variable-diameter inflatable component, allowing the device to enter pipes more easily. Once inside, inflation ensures the component adheres closely to the pipe's inner wall, facilitating better scraping and dust removal. The variable-diameter component also makes it suitable for use in pipes of various sizes, offering broad applicability. A displacement mechanism allows the device to move within the pipe, cleaning accumulated dust deep within. Furthermore, a single air pump can simultaneously create negative pressure on the dust collection ring and bag while inflating the component, enhancing the device's efficiency.

[0052] Preferably, the support frame 1 is equipped with a storage battery 11, which provides energy to the air pump 6 and the displacement assembly 3.

[0053] Preferably, four dust collection bags 5 are provided, evenly distributed around the support frame 1. This design allows for better and more timely collection of the dust scraped off.

[0054] like Figure 7 As shown, in one embodiment, the dust collection ring 4 includes a rigid, sealed annular housing 41 and a dust collection bag 42 disposed within the housing 41. Dust from the dust collection bag 5 enters the dust collection bag 42, which has a breathable filtering function to retain dust within it. The suction end of the air pump 6 communicates with the inner cavity of the housing 41 but not directly with the interior of the dust collection bag 42. This design significantly reduces the dust content in the gas drawn into the air pump, thereby reducing the amount of dust entering the inflation component and extending the service life of the air pump and the cleaning cycle of the inflation component.

[0055] like Figure 1 , Figure 2 As shown, in one embodiment, the support frame 1 is equipped with an image acquisition device 12 and a transmission device 13. This design allows staff to remotely monitor the cleaning process inside the pipeline by installing an external signal receiving device to receive signals sent from the image acquisition device via the transmission device.

[0056] like Figure 4 , Figure 5 As shown, in one embodiment, the displacement component 3 includes two semicircular rings 31 disposed on the outside of the support frame 1, and telescopic members 32 disposed on the support frame 1 in a one-to-one correspondence with each semicircular ring 31. The telescopic members 32 are used to push the corresponding semicircular rings 31 closer to and away from the support frame 1.

[0057] Each semicircular ring 31 is provided with a traveling component 33 on its outside. The traveling component 33 is used to contact the inner wall of the pipe and push the displacement component 3 to generate displacement. With this design, the diameter of the displacement component can be changed by pushing the semicircular rings closer to and away from the support frame through the telescopic component to accommodate pipes of different sizes. It also facilitates the entry and exit of this equipment in the pipe.

[0058] Preferably, the telescopic component 32 is an electrically operated telescopic component, such as an electric push rod. The electrically operated telescopic component can be powered by a storage battery 11.

[0059] like Figure 6 As shown, in one embodiment, the traveling component 33 includes a main housing 331, at least one roller 332 disposed within the main housing 331, and a motor 333 disposed within the main housing 331. The motor 333 drives each roller 332 to rotate via a transmission belt 334. Since the specific structure of the motor driving the rollers via the transmission belt is common knowledge, only a general description is given here. This design allows the motor to drive each roller to roll along the pipe wall, thereby displacing the device within the pipe.

[0060] Preferably, multiple anti-slip blocks 335 are evenly fixedly installed on the outer surface of each roller 332. This design prevents the rollers from slipping relative to the inner wall of the pipe when they rotate inside the pipe, ensuring the normal operation of the equipment.

[0061] like Figure 4 , Figure 5 As shown, in one embodiment, a support rod 14 is provided inside the support frame 1, and a movable block 15 is provided on the support rod 14. Telescopic rods 16 are slidably installed at both ends of the movable block 15, and the other end of each telescopic rod 16 is connected to the corresponding semicircular ring 31. The telescopic component 32 is slidably disposed on the movable block 15, wherein the telescopic direction of the telescopic component 32 is the same as the sliding direction of the telescopic rod 16.

[0062] A stop block 151 is provided at the position between the two corresponding telescopic members 32 of the movable block 15, and an elastic member 152 is provided between each telescopic member 32 and the stop block 151. This design, by setting up the support rod, movable block, and telescopic rod, and connecting the telescopic rod to the corresponding semi-circular ring, further ensures the stability of the semi-circular ring, allowing it to move smoothly towards and away from the support frame. Since the dust accumulation thickness varies at different locations within the pipe, the elastic member compensates for the gap between the pipe and the semi-circular ring caused by the varying dust accumulation thickness, ensuring that the traveling component always fits against the inner wall of the pipe, guaranteeing the device's smooth movement within the pipe.

[0063] Preferably, the elastic element 152 is a spring.

[0064] Preferably, a slot 311 is provided at the corresponding positions of the telescopic component 32 and the telescopic rod 16 of the semicircular ring 31. A retaining plate 34 is fitted into the slot 311, and the ends of the telescopic component 32 and the telescopic rod 16 are connected to the retaining plate 34. This design allows for better connection and separation between the semicircular ring and the telescopic component and the telescopic rod, facilitating maintenance and replacement.

[0065] like Figure 4 , Figure 5 As shown, in one embodiment, a wind-driven component 7 is disposed in the middle of the support frame 1. The wind-driven component 7 includes multiple fan blades and is fixedly connected to the support frame 1. The fan blades do not rotate relative to the support frame 1. With this design, when the device is placed inside a duct, the airflow inside the duct blows towards the fan blades, causing the blades to generate a rotational force. This rotational force is transmitted to the support frame, giving the entire device a rotational force. Under the action of this force, combined with the displacement component, the device can rotate and move forward within the duct, thus better cleaning accumulated dust inside the duct. This method of using wind energy within the duct to enable the device to rotate during movement without using battery power meets current requirements for energy conservation and environmental protection, and the design is quite ingenious.

[0066] like Figure 5 As shown, in one embodiment, the two ends of the semicircular ring 31 are provided with pressing members 35. The pressing member 35 includes an arc-shaped plate 351, which is rotatably mounted on the corresponding semicircular ring 31. A torsion spring 352 is provided at the connection position between the arc-shaped plate 351 and the semicircular ring 31, and the torsion spring 352 causes the arc-shaped plate 351 to be in an outwardly open state. With this design, when inside the pipe, the arc-shaped plate is always pressed against the inner wall of the pipe by the action of the torsion spring, so that the device is always in the middle of the pipe during the dust removal operation, which can better clean the inner wall of the pipe.

[0067] Preferably, a hook 17 is provided at the bottom of the support frame, and a connecting cable 18 is movably engaged at the rear end of the hook 17. This design allows the device to be pulled out of the pipe by the connecting cable. When the device is stuck in the pipe or loses power, it can be quickly pulled out of the pipe by the connecting cable.

[0068] like Figure 4 , Figure 9As shown, in one embodiment, a through-hole limiting groove 312 is provided at the position of the corresponding ash storage bag 5 within the semicircular ring 31. The ash storage bag 5 is placed within the corresponding limiting groove 312. A tension ring 51 is provided inside the bag opening of each ash storage bag 5. The tension ring 51 is used to open the bag opening of the ash storage bag 5. A rotating shaft 52 is provided inside the tension ring 51. Rotating plates 53 are provided on both sides of the rotating shaft 52 along its length. This design uses the tension ring to keep the bag opening of the ash storage bag open at all times, which is convenient for adsorbing the ash scraped off by the cleaning component. By setting the rotating shaft and rotating plates, the rotating plates rotate rapidly within the tension ring after being subjected to a backward adsorption force, thereby preventing ash from clogging the front opening of the ash storage bag.

[0069] like Figure 8 As shown, in one embodiment, the inflatable component 22 includes a retainer 222, an airbag 223 disposed within the retainer 222, and a scraper 224 disposed on the top of the airbag 223. When the airbag 223 inflates, it pushes the scraper 224 upward, using the scraper 224 to scrape off dust from the inner wall of the pipe. A limit frame 225 is installed inside the airbag 223 at the position corresponding to the air inlet of the airbag 223. An eccentric wheel 226 is installed on the limit frame 225, and a blowing blade 227 is disposed on the eccentric wheel 226. When the gas in the airbag 223 flows through the blowing blade 227, the blowing blade 227 drives the eccentric wheel 226 to rotate under the blowing of the airflow, thereby causing the inflatable component 22 to vibrate during scraping and dust removal, which can quickly shake off the dust inside the pipe and the dust adhering to the surface of the inflatable component 22, improving the dust removal efficiency.

[0070] It should be noted that this application can be used not only for scraping and dust removal in ventilation ducts, but also for scraping and dust removal in other ducts.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
