Description

Technical Field

[0001] The present application relates to the technical field of boiler monitoring, and more specifically, to a boiler flame monitoring device. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. In order to facilitate intuitive understanding of the flame combustion in the furnace, an observation window is usually installed on the boiler for viewing at any time. After long-term use, dust will accumulate on the inside of the observation window, which will affect the viewing. The patent document with the prior art publication number CN220229261U provides an observation device for boiler flame monitoring. The device uses an elastic scraper assembly to enable the scraper to always be close to the glass plate, ensuring the cleaning effect. At the same time, the cleaning mechanism has less obstruction to the glass plate, and only the scraper position partially obstructs the glass plate. Compared with ordinary scraper flange sight glasses, the observation effect is better.

[0003] In view of the above-mentioned related technologies, the inventor believes that since the scraper performs circular rotation to scrape the glass dust, some dust will accumulate on one side of the scraper and cannot be discharged, thus affecting the subsequent cleaning of the glass. Therefore, we propose a boiler flame monitoring device. Utility Model Content

[0007] Optionally, through holes are provided at both ends of the lifting plate, the driving rod is slidably matched with the through holes, and the driving rod is eccentrically connected and fixed to the gear.

[0008] By adopting the above technical solution, when the gear rotates, the driving rod makes a circular motion, and the two driving rods rotate in opposite directions, so that the lifting plate can be driven to perform a rapid up and down reciprocating motion during the lifting process, thereby improving the cleaning effect of the brush on the glass plate.

[0009] Optionally, the rotating rod A and the rotating rod B are arranged in a V shape, and the two rotating rods A and the rotating rods B are arranged symmetrically.

[0010] By adopting the above technical solution, when the two rotating rods B rotate in opposite directions, the rotating rods B cooperate with the rotating rods A to enable the two gears to always maintain the same horizontal height for displacement, thereby driving the lifting plate to perform vertical lifting.

[0011] Optionally, both ends of the coupling are transmission-connected to the rotating rod B via a steering gear, and the middle portion of the coupling is transmission-connected to a handwheel via a steering gear, and the handwheel is arranged on a side of the window panel away from the coupling.

[0012] By adopting the above technical solution, the hand wheel is turned to drive the coupling shaft to rotate, and the steering gears on both sides of the coupling shaft are set in opposite directions, so that the coupling shaft drives the rotating rods B at both ends to rotate in opposite directions.

[0013] Optionally, the height of the rack is higher than that of the glass plate, and a cleaning plate fixedly connected to the window plate is provided on the lower side of the glass plate, and the cleaning plate is in frictional contact with the brush.

[0014] By adopting the above technical solution, after the lifting plate is lowered to below the glass plate, the brush can contact the cleaning plate, so that the dust adhering to the brush can be removed, thereby achieving self-cleaning.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. When the rotating rod B and the rotating rod A rotate through the connecting shaft, the gear drives the lifting plate to descend. At the same time, the gear and the rack cooperate to make the driving rod drive the lifting plate to move up and down quickly, so that the brush can effectively clean the dust on the glass plate and scrape the dust to the lower side of the glass plate, which is practical.

[0017] 2. When the brush contacts the cleaning brush, the dust adhering to the brush can be removed, achieving self-cleaning of the brush and improving the cleaning effect during subsequent cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
