Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to intelligent multifunctional smoke exhaust pipeline cleaning equipment. Background Art

[0002] Existing smoke exhaust duct cleaning robots all use high-pressure nozzles to flush to remove oil stains on the inner wall of the duct. In order to more comprehensively clean the inner wall of the oil fume duct, the nozzle of the cleaning robot generally adopts two designs. One is a nozzle with pitch adjustment and left and right adjustment. The advantage is that the spray angle of the nozzle can be freely adjusted, and at the same time, the nozzle can be closer to the inner wall of the duct to deal with stubborn oil stains. The disadvantage is that the staff needs to manually control the operation and adjust it in real time. The second is that the nozzle has a fixed spray angle, but the nozzle can continue to rotate 360 ​​degrees. The advantage is that the operator does not need to adjust it in real time, but the nozzle position is fixed, and the spraying intensity is determined by the distance from the nozzle to the inner wall of the duct. For this reason, we propose an intelligent multifunctional smoke exhaust duct cleaning equipment. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: an intelligent multifunctional smoke exhaust pipe cleaning device, comprising a pipe 1, a crawler-type walking chassis 11 placed in the pipe 1, and a mounting block 12 arranged on the crawler-type walking chassis 11, and also comprising:

[0037] The L-shaped guide tube 2 is rotatably mounted on the mounting block 12 through a bearing and is used to guide the cleaning fluid;

[0038] A sliding nozzle 3, one end of which is located in the L-shaped conduit 2 and is slidably connected thereto, and a nozzle is installed at one end of the sliding nozzle 3;

[0039] A guide wheel 4 is rotatably arranged on the sliding nozzle 3;

[0040] The elastic member 5 is arranged on the L-shaped conduit 2 and connected to the sliding nozzle 3, and the elastic member 5 drives the guide wheel 4 to press against the inner wall of the pipeline 1;

[0041] The rotating assembly 6 is arranged on the mounting block 12 and is used to drive the L-shaped guide tube 2 to rotate so that the spray head rotates to spray water;

[0042] When in use, the driving motor 56 is started to drive the sliding nozzle 3 to rotate, and the pressure spring 53 is used to drive the guide wheel 4 to roll along the inner wall of the pipeline 1, so that the nozzle can adjust the distance from the inner wall of the pipeline 1 in real time to ensure that it is always close to the inner wall of the pipeline 1, thereby improving the cleaning effect;

[0043] At the same time, during the rotation of the nozzle, the paddle 61 is used to slide along the inner wall of the pipe 1. When the nozzle is deflected, the linkage assembly 65 is used to ensure that one side of the paddle 61 is always in a vertical position against the inner wall of the pipe 1. Then, when the nozzle is deflected, the paddle 61 is used to fit the inner wall of the pipe 1 to detect the thickness of the oil stain on the inner wall of the pipe 1. When the oil stain is thicker, the paddle 61 deflects more, so the subsequent nozzle is allowed to rotate more slowly when cleaning this part, thereby extending the flushing time of this section of the pipe 1 and improving the flushing effect.

[0044] The elastic member 5 includes a hollow shaft 1 51 rotatably connected to the L-shaped conduit 2 via a bearing, a shaft 2 52 is slidably connected inside the hollow shaft 1 51, one end of the shaft 2 52 is rotatably connected to the sliding nozzle 3 via a bearing, a pressure spring 53 is sleeved on the L-shaped conduit 2, and the two ends of the pressure spring 53 are respectively fixedly connected to the L-shaped conduit 2 and the sliding nozzle 3. When the sliding nozzle 3 is perpendicular to the inner wall of the pipeline 1, the pressure spring 53 is in a compressed state, deflecting the L-shaped conduit 2, and the sliding nozzle 3 is extended by resetting the pressure spring 53, so that the nozzle can adjust the distance from the inner wall of the pipeline 1 in real time to ensure that it is always close to the inner wall of the pipeline 1;

[0045] A shaft 3 54 is fixedly connected to the guide wheel 4, an L-shaped bracket 55 is fixedly connected to the sliding nozzle 3, and the shaft 3 54 and the L-shaped bracket 55 are rotatably connected via a bearing.

[0046] The rotating assembly 6 includes a driving motor 56 fixedly connected to the mounting block 12, a gear set 57 is installed in the mounting block 12, the L-shaped catheter 2 is connected to the driving motor 56 by the gear set 57, the driving motor 56 is started to drive the L-shaped catheter 2 to rotate by the gear set 57, the gear set 57 includes a gear 1 fixedly connected to the L-shaped catheter 2, and a gear 1 is also fixedly connected to the output shaft of the driving motor 56, and the two gears 1 are meshed.

Four paddles 61 are evenly and equidistantly arranged at one end of the shaft 4 59. When the inner wall of the pipeline 1 is free of debris, the guide wheel 4 is close to the inner wall of the pipeline 1, and the paddle 61 is also perpendicular to the inner wall of the pipeline 1 and has a certain distance from the inner wall of the pipeline 1. A controller 62 is installed on the driving motor 56, and a detection component 63 is arranged on the mounting frame 58. The detection component 63 is connected to the shaft 4 59. The four paddles 61 correspond to the inner walls of the four sides of the rectangular pipeline 1 and deflect the sliding nozzle 3. In the process of driving the paddle 61 to move along the inner wall of the pipeline 1, the oil blocks the paddle 61 to deflect it. At the same time, the detection component 63 is used to detect and send a signal to the controller 62 to control the speed of the driving motor 56 to reduce;

[0048] Specifically, the length of the pipe 1 cleaned by the nozzle rotating one circle is one unit, and the distance of the inner wall of the pipe 1 swept by the paddle 61 rotating one circle is also one unit. Therefore, when the nozzle rotates one circle to clean one unit of the pipe 1, the paddle 61 also detects the distribution of oil stains on the inner wall of the next unit of the pipe 1, and collects and sorts them through the controller 62. Then, when the device body moves forward one unit of the pipe 1 to clean the inner wall of the next unit of the pipe 1, it can rotate and clean according to the information collected by the controller 62. Specifically, where the oil stain is thicker, the driving motor 56 rotates slower, and where the oil stain is thinner, the driving motor 56 rotates faster, thereby improving the cleaning efficiency and the cleaning effect, which is more efficient and intelligent.
