Description

Technical Field

[0001] This application relates to the field of channel cleaning technology, specifically to a channel cleaning device. Background Technology

[0002] The inner walls of smoke exhaust ducts are usually covered with a lot of dust and tar. Dust and tar can easily form scale on the inner walls of the duct under high temperature, which affects the smoke exhaust effect of the duct and also poses a safety hazard.

[0003] In related technologies, carbon wires are manually fed in and dragged back and forth to clean the tar and dust on the inner wall of the channel. However, due to the long channel, manual cleaning is not possible, resulting in low efficiency and difficulty in completely removing stains. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this application aims to provide a channel cleaning device.

[0005] According to this application, a channel cleaning device is provided, comprising:

[0006] Support frame;

[0007] A cleaning mechanism is connected to the support frame. The cleaning mechanism is in contact with the inner wall of the channel. The cleaning mechanism rotates relative to the inner wall of the channel to clean the inner wall of the channel.

[0008] A drive wheel is connected to the support frame. The support frame applies pressure to the drive wheel so that the drive wheel abuts against the inner wall of the channel. The drive wheel rotates to drive the support frame and the cleaning mechanism to move along the extension direction of the channel.

[0009] In one possible implementation, the support frame includes:

[0010] At least two support rod groups, each of which is arranged at circumferential intervals.

[0011] In one possible implementation, the support rod assembly includes:

[0012] A support sleeve rod extends radially along the channel, and the interior of the support sleeve rod is provided with a receiving cavity;

[0013] An elastic element is disposed within the receiving cavity;

[0014] A telescopic rod, one end of which extends into the receiving cavity and compresses the elastic element, the other end of which is connected to the drive wheel, the elastic element being configured to apply an elastic force to the telescopic rod pointing towards the inner wall of the channel.

[0015] In one possible implementation, the channel cleaning device includes:

[0016] A controller, electrically connected to the drive wheel, is used to control the rotation of the drive wheel.

[0017] In one possible implementation, the support frame is provided at both ends of the cleaning mechanism in the direction of the channel's extension.

[0018] In one possible implementation, the cleaning mechanism includes:

[0019] The scraper contacts the inner wall of the channel;

[0020] A connecting part is attached to the side of the scraper away from the inner wall of the channel;

[0021] A connecting sleeve rod, the outer wall of which is connected to the end of the connecting part that is away from the scraper;

[0022] A drive assembly is connected to the connecting sleeve rod, and the drive assembly drives the connecting sleeve rod to rotate so that the scraper rotates relative to the inner wall of the channel.

[0023] In one possible implementation, the driving component includes:

[0024] The motor is located inside the connecting sleeve rod;

[0025] A drive shaft is disposed inside the connecting sleeve rod, the output end of the motor is connected to the drive shaft, and the drive shaft is connected to the connecting sleeve rod in a driving connection.

[0026] In one possible implementation, the scraper is provided with a bristle portion located on the side of the scraper that abuts against the inner wall of the channel.

[0027] In one possible implementation, it also includes:

[0028] A vacuuming device is connected to the support frame and is used to vacuum the channel.

[0029] In one possible implementation, the vacuuming device includes:

[0030] A dust suction hood is connected to the support frame and has a dust suction port.

[0031] A suction channel, one end of which is connected to the suction port;

[0032] A vacuum cleaner is connected to the suction channel;

[0033] A dust collection box is connected to the other end of the suction channel.

[0034] The advantages of this application are as follows: In this disclosure, by setting a support frame to apply pressure to the drive wheel, the friction between the drive wheel and the inner wall of the channel is increased, allowing the channel cleaning device to overcome gravity and remain at any height within the channel. When the inner diameter of the channel changes, the support frame can drive the drive wheel to move, ensuring that the drive wheel always abuts against the inner wall of the channel. This ensures that the friction between the drive wheel and the inner wall of the channel can always overcome gravity, preventing the channel cleaning device 1 from slipping due to insufficient friction. By rotating the drive wheel forward or backward on the wall of the channel, the channel cleaning device can move upward or downward along the extension direction of the channel, facilitating a thorough cleaning of the inner wall of the channel in the extension direction, saving labor costs and improving cleaning efficiency.

[0035] Other features and advantages of this application will be set forth in the following description and will be apparent in part from the description or learned by practicing the application. The purposes and other advantages of this application may be realized and obtained by means of the structures particularly pointed out in the description, claims and drawings.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and feature vectors in the embodiments of this application can be arbitrarily combined with each other.

[0043] The inner walls of smoke exhaust ducts are often covered with a large amount of dust and tar. High temperatures can cause this dust and tar to easily form scale on the duct walls, affecting the smoke exhaust efficiency and posing safety hazards. Current techniques involve manually dragging carbon wires back and forth to clean the tar and dust from the duct walls. However, due to the long length of the duct, manual cleaning is inefficient and fails to completely remove the stains.

[0044] To address the aforementioned problems, this application provides a channel cleaning device, comprising: a support frame, a cleaning mechanism, and a drive wheel. The cleaning mechanism is connected to the support frame and contacts the inner wall of the channel. The cleaning mechanism rotates relative to the inner wall of the channel to clean it. The drive wheel is connected to the support frame, and the support frame applies pressure to the drive wheel to make it abut against the inner wall of the channel. The drive wheel rotates to move the support frame and the cleaning mechanism along the extension direction of the channel, thereby facilitating the cleaning of scale on the inner wall of the channel and improving the efficiency of channel cleaning.

[0045] An exemplary embodiment of this application provides a channel cleaning device 1, see [link to example]. Figs. 1-3 It includes a support frame 11, a cleaning mechanism 12, and a drive wheel 13.

[0046] The cleaning mechanism 12 is connected to the support frame 11. When cleaning the inner wall of the channel 10, the support frame 11 is placed inside the channel 10. The drive wheel 13 is connected to the support frame 11. The support frame 11 applies pressure to the drive wheel 13, causing the drive wheel 13 to abut against the inner wall of the channel 10, thereby increasing the friction between the drive wheel 13 and the inner wall of the channel 10, allowing the channel cleaning device 1 to remain at any height within the channel 10. The support frame 11 is made of metal to ensure sufficient strength and stability. The cleaning mechanism 12 contacts the inner wall of the channel 10. The inner wall of the channel 10 is cleaned by the rotation of the cleaning mechanism 12 relative to the inner wall of the channel 10. The rotation of the drive wheel 13 drives the support frame 11 and the cleaning mechanism 12 to move along the extension direction of the channel 10.

[0047] In this embodiment, by setting the support frame 11 to apply pressure to the drive wheel 13, the friction between the drive wheel 13 and the inner wall of the channel 10 is increased, allowing the channel cleaning device 1 to overcome gravity and remain at any height within the channel 10. When the inner diameter of the channel 10 changes, the support frame 11 can drive the drive wheel 13 to move, ensuring that the drive wheel 13 always abuts against the inner wall of the channel 10. This ensures that the friction between the drive wheel 13 and the inner wall of the channel 10 can always overcome gravity, preventing the channel cleaning device 1 from slipping due to insufficient friction. By rotating the drive wheel 13 forward or backward on the wall of the channel 10, the channel cleaning device 1 can move upward or downward along the extension direction of the channel 10, facilitating the cleaning mechanism 12 to thoroughly clean the inner wall of the channel 10 in the extension direction, saving labor costs and improving cleaning efficiency.

[0048] In some embodiments, see Figs. 1-3 The support frame 11 includes at least two support rod groups 111, which are arranged circumferentially. Each support rod group 111 has a first end and a second end opposite to each other. The first ends of each support rod group 111 are connected, and the second ends of each support rod group 111 extend radially outward. Each second end of each support rod group 111 is connected to a corresponding drive wheel 13. The at least two support rod groups 111 allow the support frame 11 to be supported against the inner wall of the channel 10 in at least two directions, thereby improving the stability of the support frame 11 within the channel 10 and enabling the channel cleaning device 1 to be more stably supported against the inner wall of the channel 10. For example, the support rod groups 111 are configured as telescopic elastic rod groups, so that elastic force can be applied to the drive wheel 13 through the telescopic elastic rod groups. This allows the support rods to automatically adapt to different inner diameters of the channel 10 when the inner diameter changes, ensuring friction between the drive wheel 13 and the inner wall of the channel 10 and preventing the channel cleaning device 1 from slipping.

[0049] In some embodiments, see Figs. 1-3The support rod assembly 111 includes a support sleeve 1111, an elastic element, and a telescopic rod 1112. The support sleeve 1111 extends radially along the channel 10, and a receiving cavity is provided inside the support sleeve 1111. The elastic element is disposed within the receiving cavity, with one end of the elastic element abutting against the inner wall of the receiving cavity. One end of the telescopic rod 1112 extends into the receiving cavity and compresses the elastic element, while the other end of the telescopic rod 1112 is connected to the drive wheel 13. The elastic element is configured to apply an elastic force towards the inner wall of the channel 10 to the telescopic rod 1112. The channel cleaning device 1 is installed inside the channel 10 to clean the channel 10. Due to the limitation of the inner diameter of the channel 10, the drive wheel 13 abuts against the inner wall of the channel 10 and forces the telescopic rod 1112 to apply pressure to the elastic element, so that the elastic element is in a compressed state. The elastic element applies elastic force to the telescopic rod 1112 so that the drive wheel 13 always abuts against the inner wall of the channel 10, thereby increasing the friction between the drive wheel 13 and the inner wall of the channel 10 and preventing the channel cleaning device 1 from slipping.

[0050] In some embodiments, the channel cleaning device 1 includes a controller electrically connected to a drive wheel 13, which controls the rotation of the drive wheel 13. The drive wheel 13 is configured as a self-driving wheel, rotating forward or backward according to the instructions transmitted by the controller, thereby enabling the channel cleaning device 1 to move up and down along the extension direction of the channel 10.

[0051] For example, the controller may be equipped with a receiving module for receiving signals and transmitting control signals through a remote control device. After receiving the control signal, the receiving module controls the rotation of the drive wheel 13 according to the instructions of the control signal.

[0052] In some embodiments, support frames 11 are provided at both ends of the cleaning mechanism 12 in the extension direction of the channel 10. This is beneficial for the cleaning mechanism 12 to support the channel cleaning device 1 at both ends, thereby enhancing the overall stability of the channel cleaning device 1 during operation and preventing the channel cleaning device 1 from deviating from its path or tilting due to vibrations generated during cleaning operations or different rotation speeds of the drive wheel 13. This ensures the stable operation of the channel cleaning device 1.

[0053] In some embodiments, see Figs. 1-3 The cleaning mechanism 12 includes a scraper 121, a connecting part 122, a connecting sleeve 123, and a drive assembly.

[0054] The scraper 121 contacts the inner wall of the channel 10. The outer surface of the scraper 121 that contacts the inner wall of the channel 10 is arc-shaped to increase the contact area with the channel 10 and improve the cleaning efficiency of the scale adhering to the inner wall of the channel 10. The scraper 121 rotates circumferentially along the channel 10 to clean the inner wall of the channel 10.

[0055] The connecting part 122 is connected to the side of the scraper 121 away from the inner wall of the channel 10. The connecting part 122 is configured as a connecting plate. For example, the connecting part 122 can be configured as a fan-shaped plate, and the edge of the fan-shaped plate is adapted to connect with the scraper 121 to enhance the connection strength between the connecting part 122 and the scraper 121. The outer wall of the connecting sleeve 123 is connected to the end of the connecting part 122 away from the scraper 121, and the connecting sleeve 123 and the connecting part 122 can rotate synchronously.

[0056] The drive assembly is connected to the connecting sleeve 123 for transmission. The drive assembly drives the connecting sleeve 123 to rotate so that the scraper 121 rotates relative to the inner wall of the channel 10, thereby cleaning the inner wall of the channel 10.

[0057] In some embodiments, the drive assembly includes a motor and a drive shaft. The motor is electrically connected to a controller, which controls the starting of the motor. Both the motor and the drive shaft are disposed inside the connecting sleeve 123. The output end of the motor is connected to the drive shaft, and the drive shaft is drively connected to the connecting sleeve 123. The rotation of the motor's output shaft drives the drive shaft to rotate, and the drive shaft drives the connecting sleeve 123, the connecting part 122, and the scraper 121 to rotate synchronously, thereby cleaning the inner wall of the channel 10.

[0058] In some embodiments, see Figs. 1-3 The scraper 121 is provided with a bristle portion 124, which is located on the side of the scraper 121 that abuts against the inner wall of the channel 10, facilitating deep cleaning of the gaps and grooves in the inner wall of the channel 10. The bristles can easily reach complex structural areas that are difficult for the scraper 121 to reach, loosening and sweeping away attached dust, debris, and other contaminants. For example, the bristle portion 124 is made of high-temperature resistant and wear-resistant nylon material, and the scraper 121 is made of high-strength and corrosion-resistant stainless steel material.

[0059] In some embodiments, the channel cleaning device 1 further includes a vacuuming device 14. The vacuuming device 14 is connected to the support frame 11 and is used to vacuum the channel 10 to promptly clean up scraped-off scale and the mixture of dust and tar, thus avoiding secondary pollution.

[0060] See Figs. 1-3 The vacuuming device 14 includes a vacuum hood 141, a vacuum channel 142, a vacuum cleaner 143, and a dust collection box 144. The vacuum hood 141 is connected to the support frame 11 and can move along the extension direction of the channel 10 with the support frame 11 to catch the mixture of dust and tar that falls on it. The vacuum hood 141 is funnel-shaped, with a suction port at the bottom. The diameter of the opening at the top of the vacuum hood 141 is larger than the diameter of the suction port at the bottom, so as to collect the mixture of dust and tar that falls into the vacuum hood 141 into the suction port.

[0061] One end of the suction channel 142 is connected to the suction port, and the other end of the suction channel 142 is connected to the dust collection box 144. The vacuum cleaner 143 is connected to the suction channel 142. The vacuum cleaner 143 is used to create negative pressure inside the suction channel 142, so that air flows into the suction channel 142 through the suction port and sucks the mixture of dust and tar that falls into the suction hood 141 into the suction channel 142. The mixture of dust and tar flows into the dust collection box 144 through the suction channel 142 to achieve unified collection of the mixture of dust and tar.

[0062] The channel cleaning device 1 of this embodiment is suitable for channels 10 with an inner diameter of 300mm-800mm. The cleaning method of the channel cleaning device 1 is as follows:

[0063] The channel cleaning device 1 is used to clean the inner wall of the chimney. The device is installed inside the chimney, with the drive wheel 13 abutting against the inner wall. Then, the controller controls the drive wheel 13 to rotate, raising the channel cleaning device 1 to the top of the chimney where the dirt is. Next, the motor is started, causing the scraper 121 to rotate. The brush head 124 and the scraper 121 work simultaneously to brush and scrape away the dirt from the inner wall of the chimney. Simultaneously, the vacuuming device 14 is activated to collect dust and debris generated during the cleaning process. The controller controls the drive wheel 13 to rotate, causing the channel cleaning device 1 to gradually descend to the bottom of the chimney. The channel cleaning device 1 cleans as it descends, thus thoroughly cleaning the entire inner wall of the chimney.
