Description

Technical Field

[0001] This utility model belongs to the field of cleaning robots, and in particular relates to a dust collection mechanism and an inspection cleaning robot having the same. Background Technology

[0002] In some special industries, such as construction, inspection is essential. With the increasing mobility of robots, they can replace humans in high-risk or health-damaging work environments.

[0003] In dusty working environments, robots are often required to perform dust suppression during inspections. Traditional dust suppression mechanisms use impeller rotation as the driving source for dust suppression. Most of the dusty gas passes through the impeller, which causes high wear and tear. At the same time, it cannot handle large impurities, which have a high impact on the impeller, ultimately leading to high dust suppression costs.

[0004] Regarding gas adsorption force, traditional devices use a constant method, which can lead to large impurities having a large impact inertia when the flow rate is too high, which can also affect the dust collection mechanism. Summary of the Invention

[0005] In view of this, the present invention aims to propose a dust collection mechanism and an inspection and cleaning robot having the same, so as to solve the problems that traditional inspection robots are prone to self-damage and drive source damage during dust collection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of the present invention, a dust collection mechanism is provided, comprising:

[0007] The outer shell is hollow in shape and is provided with an air inlet, an air outlet and a material outlet. The air outlet is provided with a nozzle facing the side away from the inside of the outer shell. The ejector is provided with an impact-resistant part on the side of the inside of the outer shell.

[0008] A flexible baffle assembly is disposed inside the housing and arranged opposite to the air inlet end;

[0009] The diameter changing component is located at the air outlet end and is used to change the communication area between the air outlet end and the inside of the housing.

[0010] The filter assembly is located at the air outlet.

[0011] When the ejector ejects gas from the housing, the elastic baffle assembly is used to contact the dust-laden gas drawn in at the inlet end, so that some of the object is separated from the dust-laden gas and discharged from the outlet end.

[0012] Furthermore, the air inlet and air outlet are located on two oppositely arranged wall surfaces of the housing.

[0013] Furthermore, the outer shell wall between the air inlet and the discharge outlet is an inclined surface, and the height of the discharge outlet is lower than the height of the air inlet.

[0014] Furthermore, the elastic baffle assembly includes a baffle portion arranged opposite to the air inlet end and slidably disposed within the housing, a sliding support portion disposed on the side of the baffle portion away from the air inlet end and connected to the inner wall of the housing, and an elastic portion connecting the baffle portion and the sliding support portion.

[0015] Furthermore, the elastic stop assembly also includes a sliding part, one end of which is connected to the stop part, and the other end can slide through the sliding support part and then be connected to the limiting part. When the elastic part is relaxed, the end face of the limiting part near the elastic part abuts against the sliding support part.

[0016] Furthermore, the side of the baffle near the air inlet end is an inclined end face, and the angle between this end face and the horizontal plane near the air inlet end is an acute angle.

[0017] Furthermore, the included angle is 45 degrees.

[0018] Furthermore, the aperture changing component includes a movable blocking part and a driving part. The movable blocking part is movably connected to the air outlet end, and the driving part is used to drive the movable blocking part to change the blocking area on the air outlet end.

[0019] Furthermore, the driving unit is a linear driving assembly including a fixed part and a movable part capable of linear movement relative to the fixed part. The fixed part is rotatably connected to the inner wall of the housing, and the movable part is rotatably connected to the movable shielding part.

[0020] According to another aspect of the present invention, an inspection and cleaning robot is provided, including a dust collection mechanism as described above.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This dust collection mechanism uses an ejector to extract gas from the back pressure zone as a power source for dust collection. An impact-resistant part is provided on the side of the ejector near the back pressure zone to protect the ejector from damage. By using an ejector instead of a traditional impeller and providing protection through the impact-resistant part, the ejector as a power source can be guaranteed to be undamaged.

[0023] 2. This dust collection mechanism is equipped with an elastic baffle component, which can come into contact with the sucked-in airflow. When large impurities come into contact with the elastic baffle component under the action of inertia, they can be separated from the gas and discharged from the discharge end, preventing large pieces of material from damaging the ejector as they move with the gas.

[0024] 3. This dust collection mechanism changes the connection area between the outlet end and the outer shell by setting a diameter changing component, which can change the flow rate and pressure of the ejected gas, thereby causing corresponding periodic changes in pressure and flow rate, preventing large impurities in the dust-laden gas from moving too fast and causing excessive wear on the elastic baffle component.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] Referring to the accompanying drawings, this embodiment is provided according to one aspect of the present invention: a dust collection mechanism, comprising:

[0039] The outer shell 1 is hollow and has an air inlet 1-1, an air outlet 1-2, and a material outlet 1-3. An ejector 3 with nozzles facing away from the interior of the outer shell 1 is arranged inside the air outlet 1-2. An impact-resistant part 4 is provided on the side of the ejector 3 closest to the interior of the outer shell 1. The specific shape of the outer shell 1 can be designed according to the actual needs of the inspection robot to be installed, and any form that meets the usage requirements and helps reduce gas flow resistance is acceptable. In this application, a flat box structure with a long rectangular cross-section is adopted. The strength of the box should meet the corresponding requirements of the usage environment. For example, in the construction industry, where there is a large amount of dust and many blocky materials, damage is easily caused, so materials with strong impact resistance should be selected. To facilitate the installation of internal components, an opening can be provided on one side and sealed with a blind flange. The blind flange and the box can be fixed with bolts or snap-fit ​​devices to improve the convenience of connection, depending on the actual needs. To improve service life, wear-resistant plates can be added to the easily damaged parts of the inner wall of the outer shell 1. The ejector 3 can be any existing jet ejector, fixed to the impact-resistant part 4 with bolts. The impact-resistant part 4 is fixed to the inside of the outlet end 1-2 with bolts. To facilitate adjustment of the diameter of the outlet end 1-2, it is cylindrical and sealed to the filter assembly 6 with a gasket. Bolt fixing is an option. The impact-resistant part 4 is made of a wear-resistant and impact-resistant material, such as high manganese steel. The side of the impact-resistant part 4 near the back pressure zone is hemispherical, which can guide the particles in the gas, reduce wind resistance, and reduce wear. The inlet end 1-1 and the outlet end 1-2 are located on two oppositely arranged walls of the outer shell 1. This arrangement can effectively reduce wind resistance and form a smooth gas flow path. Other arrangements can also be used in this application, but it should be ensured that the gas enters from the inlet end 1-1 and first contacts the elastic baffle assembly 2 to help separate large impurities.

[0040] The elastic baffle assembly 2 is disposed inside the housing 1 and is arranged opposite to the air inlet 1-1. The elastic baffle assembly 2 is designed to separate large objects in the airflow from the airflow. Specifically, it is better to set it to a certain degree of elastic floating form so that it can use its own elasticity to reduce the damage caused by the impact after being impacted.

[0041] The diameter changing component 5 is set at the air outlet 1-2 and is used to change the communication area between the air outlet 1-2 and the inside of the outer shell 1. The purpose of setting the diameter changing component 5 is to change the communication area, so that when the ejector 3 sprays air, the gas velocity and pressure in the back pressure zone can be changed by changing the communication area. The air velocity will be accelerated or slowed down accordingly. When the airflow carries dust and blocky impurities, the blocky material will not be in a continuous acceleration motion, preventing it from contacting the elastic baffle component 2 with a large impact inertia after entering the outer shell 1.

[0042] The filter assembly 6 is located at the air outlet 1-2. The filter assembly 6 can be an industrial filter element. To facilitate the installation of the filter assembly 6 and the air outlet 1-2, flanges can be installed on both the air outlet 1-2 and the filter assembly 6, and then connected with bolts. After connection, airtightness must be ensured. The filter assembly 6 can be a pipe with a flange, and a groove for embedding the filter element is set on the pipe. The filter element embedded in the groove filters the gas passing through the flange pipe, thus completing the dust reduction work.

[0043] When the ejector 3 ejects the gas inside the outer shell 1, the elastic baffle assembly 2 is used to contact the dust-laden gas sucked into the air inlet 1-1 so that some of the object is separated from the dust-laden gas and discharged from the outlet 1-3.

[0044] In this embodiment, the outer wall of the outer shell 1 between the air inlet 1-1 and the discharge end 1-3 is inclined, and the height of the discharge end 1-3 is lower than the height of the air inlet 1-1. This arrangement is to allow the lumpy material to move smoothly along the inclined surface to the discharge end 1-3 for discharge after being separated from the airflow. A box for collecting lumpy impurities can be set below the discharge end 1-3. When installed on an inspection robot, a corresponding channel can be set to connect the discharge end 1-3 with the box. The box is inserted into the body of the inspection robot in a pull-out manner, making it easy to remove and empty it as needed.

[0045] In this embodiment, the elastic baffle assembly 2 includes a baffle portion 2-1 arranged opposite to the air inlet end 1-1 and slidably disposed within the outer casing 1, a sliding support portion 2-5 disposed on the side of the baffle portion 2-1 away from the air inlet end 1-1 and connected to the inner wall of the outer casing 1, and an elastic portion 2-3 connecting the baffle portion 2-1 and the sliding support portion 2-5. The elastic portion 2-3 ensures that the baffle portion 2-1 can move flexibly within a certain range, thereby dissipating impact and reducing damage to the baffle portion 2-1. The baffle portion 2-1 is specifically slidably disposed within the outer casing 1, and the width of the baffle portion 2-1 should be equal to the distance between it and the inner wall of the outer casing 1. Through a sliding seal, relative movement between the baffle portion 2-1 and the inner wall of the outer casing 1 can be ensured, and gas carrying dust can be prevented from flowing away from the sliding mating surface between them, thus affecting the processing of large particles and blocky materials. The sliding seal structure adopts existing technology and will not be described in detail. The sliding support portion 2-5 is fixedly connected to the inner wall of the outer casing 1 by bolts.

[0046] In this embodiment, the elastic stop assembly 2 further includes a sliding part 2-2. One end of the sliding part 2-2 is connected to the stop part 2-1, and the other end can slide through the sliding support part 2-5 and connect to the limiting part 2-4. When the elastic part 2-3 is released, the end face of the limiting part 2-4 near the elastic part 2-3 abuts against the sliding support part 2-5. The sliding part 2-2 is mainly provided to limit the sliding path of the stop part 2-1 and prevent damage caused by internal sliding. The elastic part 2-3 is specifically selected as a spring, and the spring constant can be selected according to the actual situation.

[0047] In this embodiment, the baffle 2-1 has an inclined end face near the air inlet 1-1, and the angle between this end face and the horizontal plane near the air inlet 1-1 is an acute angle. This arrangement is to limit the reflection angle after the blocky impurities impact, allowing the blocky material to move smoothly downwards through the inclined plane to the discharge end after impact and reflection. When the angle is 45 degrees, the discharge speed of the blocky impurities is relatively fast.

[0048] In this embodiment, the aperture changing component 5 includes a movable blocking part 5-1 and a driving part 5-2. The movable blocking part 5-1 is movably connected to the air outlet 1-2, and the driving part 5-2 is used to drive the movable blocking part 5-1 to change the blocking area of ​​the air outlet 1-2. In this embodiment, two movable blocking parts 5-1 are selected and centrally symmetrically distributed with respect to the axis of the air outlet 1-2. When the two movable blocking parts 5-1 simultaneously block the air outlet 1-2 to the maximum extent, a certain opening area should still be retained to ensure the continuity of the ejection process throughout the adjustment process.

[0049] In this embodiment, the driving unit 5-2 is a linear drive assembly including a fixed part and a movable part capable of linear movement relative to the fixed part. The fixed part is rotatably connected to the inner wall of the outer casing 1, and the movable part is rotatably connected to the movable shielding part 5-1. Specifically, the driving unit 5-2 is selected as an electric cylinder. The rotatable connection method between the fixed part and the movable part and the corresponding component can be any existing method, selected according to actual needs. For the diameter changing assembly 5, selecting other forms of assemblies capable of changing the pipe diameter is also within the inventive spirit of this application.

[0050] According to another aspect of this utility model, an inspection and cleaning robot is provided, including a dust collection mechanism as described above. The dust collection mechanism can be installed on the inspection and cleaning robot by bolt fixing. The air outlet 1-2 and the filter assembly 6 should be exposed as much as possible outside the inspection and cleaning robot or in a position where the filter element can be easily replaced. Other parts of the dust collection mechanism can be installed and set according to actual needs.

[0051] The sensors, controllers, and control programs mentioned above are all existing technologies and will not be elaborated upon.

[0052] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
