Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to an automatic dust removal and cleaning mechanism for a ventilation slot. Background Art

[0002] Ventilation slots are ventilation ducts used in buildings or mechanical equipment to help expel indoor dirty air and odors, while letting in fresh air to maintain a good indoor environment. The main function of ventilation slots is to provide necessary air circulation and ventilation for buildings or equipment to maintain air quality and protect people's health. Dust, dirt and other particulate matter easily accumulate inside ventilation slots. If they are not cleaned in time, it will affect the ventilation effect and even cause blockage. Dust and dirt accumulated in ventilation slots will increase the load on ventilation equipment, reduce its efficiency, and may cause equipment failure or damage. By regularly cleaning ventilation slots, you can reduce the load on the equipment, extend the service life of the equipment, and reduce maintenance and replacement costs;

[0003] In order to achieve efficient cleaning effects, automatic dust removal and cleaning mechanisms are generally long. When encountering a corner with a large rotation angle in the ventilation slot, due to its long size, the cleaning device may collide with the ventilation slot wall or other obstacles during the turning process, resulting in the mechanism being unable to pass through the turn smoothly. This may cause the cleaning device to get stuck, clogged or damaged, thereby affecting the cleaning effect and equipment operation. In addition, the slot radius of the ventilation slot may vary due to design requirements or usage conditions. The general cleaning mechanism has a relatively fixed length and cannot be flexibly adjusted as needed, thereby limiting its ability to adapt to ventilation slots of different sizes, which can easily limit the use of the cleaning equipment and fail to meet the cleaning needs of ventilation slots of different sizes.

Dust and stains mixed with cleaning waste liquid can enter the scraper 43 until the scraper 43 rotates to the top of the collection box 41, so that the waste falls into the sewage inlet trough 42 at the top of the collection box 41 under the action of gravity for unified collection; the cleaning seat 10 rotates in A turntable 16 is connected, and a plurality of engaging sliding grooves 17 are provided on the circumference of the turntable 16.

The rotation of the turntable 16 drives the engaging sliding grooves 17 to rotate, so that the engaging columns 15 drive the sliding adjustment rod 12 to slide outward along the first sliding groove 11, so that the sliding adjustment rod 12 can drive the cleaning sponge 14 to move to fit the inner wall of the ventilation slot, so that it can adapt to different slot radii.

[0043] like Figure 1-Figure 13As shown, a plurality of adjustment limit grooves 3 are provided on the other side of the inner wall of the cleaning seat 10, and a limited sliding block 32 is slidably connected in the plurality of adjustment limit grooves 3.

[0044] The working principle of this embodiment is as follows: the first motor 18 is started, and the output end of the first motor 18 drives the turntable 16 to rotate. The turntable 16 rotates to drive the engaging sliding groove 17 provided on the turntable 16 to rotate. When the engaging sliding groove 17 rotates, the engaging column 15 is driven to move, so that the engaging column 15 drives the sliding adjustment rod 12 to slide outward along the first sliding groove 11, and the sliding adjustment rod 12 is adjusted to a suitable scale line according to the diameter of the ventilation slot to be cleaned, so that the sliding adjustment rod 12 can drive the cleaning sponge 14 to move to fit the inner wall of the ventilation slot, and when the sliding adjustment rod 12 slides outward, the scraper 43 can be driven to slide in the same direction through the connecting rod 44, so that the scraper 43 can cooperate with the cleaning sponge 14 to improve the cleaning efficiency;

[0045] At the same time, when the sliding adjustment rod 12 slides outward, the swing block 31 is squeezed by the adjusting limit groove 3, so that the limit sliding block 32 slides along the slide track of the adjusting limit groove 3. When the sliding adjustment rod 12 is adjusted to a suitable position, the swing block 31 is acted upon by the return torsion spring 34 so that the limit sliding block 32 slides and engages with the clamping groove of the adjusting limit groove 3, so that the position of the sliding adjustment rod 12 is fixed, effectively avoiding the situation in which the length of the cleaning rod changes due to excessive pressure from the ventilation slot wall during the cleaning process, thereby ensuring the stability and reliability of the cleaning device.

[0046] The hydraulic telescopic rod 74 is started, and the hydraulic telescopic rod 74 pushes the fixed shaft 73 to move to one side through the connecting sleeve 75. The fixed shaft 73 is driven by the driving force to drive the connecting wheel 71 on one side of the scissor-type lifting rod 7 to slide along the third slide groove 63 and the limiting slide groove 86 respectively, so that the scissor-type lifting rod 7 drives the fixed plate 8 to move outward until the diameter of the driving mechanism 6 is larger than the diameter of the ventilation slot, and the device is pushed into the ventilation slot. The support rod 82 is subjected to the pressure of the ventilation slot, driving the rotating shaft 81 to rotate, so that the driving mechanism 6 adapts to the slot diameter and enters the ventilation slot;

[0047] When the device completely enters the ventilation slot, the power supply of the hub motor roller 84 is started, so that the hub motor roller 84 drives the device to move slowly forward in the slot, and at the same time the second motor 21 is started, so that the second motor 21 drives the cleaning seat 10 to rotate, and the cleaning liquid in the cleaning liquid seat 13 is subjected to the centrifugal force and penetrates into the cleaning sponge 14 through the liquid seepage hole, so that the cleaning sponge 14 rotates to clean the inner wall of the ventilation slot, and then the dust and stains mixed with the cleaning waste liquid are scraped up by the scraper 43, and the dust and stains mixed with the cleaning waste liquid will remain in the scraper 43 until they fall into the sewage inlet trough 42 at the top of the collection box 41 for unified collection;

[0048] When the device encounters a corner with a smaller diameter, the first-section driving mechanism 6 first passes through the corner, and then rotates through the spherical connector 5 to drive the cleaning mechanism 1 to rotate through the corner. The second-section driving mechanism 6 finally passes through the corner through the hub motor roller 84. The three-section structure connected by the spherical connector 5 makes the device as a whole have better flexibility and adaptability, and it is easier to pass through curves with a smaller radius. At the same time, when passing through the corner, the hub motor roller 84 can adjust the rotation amplitude of the support rod 82 according to the distance from the groove wall at the corner through the cooperation of the fixed torsion spring 92 and the rotating shaft 81, so that the hub motor roller 84 can always roll forward in close contact with the inner wall of the ventilation groove.
