[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-5 As shown, this utility model is a gas-fired water-cooled low-NOx vacuum boiler, comprising:

[0028] 11. Main body of water-cooled low-NOx vacuum boiler;

[0029] The main body 11 of the water-cooled low-NOx vacuum boiler provides hot water for heating and domestic use by heating water.

[0030] The bottom end of the water-cooled low-NOx vacuum boiler body 11 is threaded with a base 12, and a flue gas outlet is provided on the upper side of one side of the water-cooled low-NOx vacuum boiler body 11.

[0031] The base 12 meets the installation requirements of the water-cooled low-NOx vacuum boiler body 11 and provides structural support. The flue gas outlet discharges the flue gas generated by the boiler.

[0032] The climbing maintenance mechanism includes a support plate 21. A bracket 22 is symmetrically fixedly connected to one end of the support plate 21, and the lower end of the bracket 22 is attached to the surface of the water-cooled low-NOx vacuum boiler body 11. A set of brackets 22 is equidistantly connected to the upper part of the upper part of the bracket 22 with a footboard 23.

[0033] The support plate 21 is installed and fixed to the bracket 22. The bracket 22, together with multiple footboards 23, forms a ladder structure for climbing during boiler maintenance.

[0034] The auxiliary maintenance mechanism includes a sliding groove 31, which is symmetrically opened on the upper position of the outer surface of the bracket 22, and a sliding block 32 is slidably provided in the sliding groove 31. A bolt hole block 33 is threadedly connected to the center position of the front of the sliding block 32.

[0035] The sliding groove 31 slides and receives the sliding block 32, and the sliding between the two can meet the needs of maintenance personnel to move to multiple positions. One end of the safety rope is fastened by the bolting hole block 33.

[0036] A movable spring 34 is fixedly connected to the lower end of the inner wall of the sliding groove 31, and the upper end of the movable spring 34 is in contact with the lower end of the sliding block 32.

[0037] The contact between the movable spring 34 and the lower end of the sliding block 32 can isolate and protect the sliding block 32 as it moves downward.

[0038] The auxiliary maintenance mechanism also includes a support block 35. A set of symmetrical threaded connections of the support block 35 are on both sides of the upper center of the outer surface of the bracket 22. One end of the inner side of the support block 35 is rotatably connected to a movable shaft 36. A movable column 37 is sleeved and fixed on one side of the outer surface of the movable shaft 36, and a limiting block 38 is provided on one side of the movable column 37 and abuts against it.

[0039] The support block 35 is mounted on the movable column 37 via the movable shaft 36. Under the action of rotation, the sliding block 32 can move upward smoothly. When the sliding block 32 moves downward, the downward movement can be stopped by the contact between the limiting block 38 and the limiting column, thus achieving the purpose of preventing fall.

[0040] The climbing and maintenance mechanism also includes an anti-slip sleeve 24, which is fitted and connected to the middle of the outer surface of the pedal 23;

[0041] Anti-slip sleeve 24 improves the safety of maintenance personnel by increasing contact friction.

[0042] The end of the support plate 21 is connected to a threaded pipe 25, and the front and rear ends of the threaded pipe 25 are provided with threaded rings 26, which extend into the support plate 21.

[0043] The threaded ring 26 is used to install and fix the threaded tube 25. The support plate 21 can be installed and fixed to the outer wall by locking the threaded tube 25 with the bolt.

[0044] Working principle: During routine maintenance of the main body 11 of the water-cooled low-NOx vacuum boiler, it is necessary to climb the ladder to work at height. Before climbing, one end of the safety rope must be tied to the person and the other end to the bolting hole block 33. At this time, the person moves up step by step with the help of multiple pedals 23. During the upward movement, the sliding block 32 slides up in the sliding groove 31 to meet the requirements. During the upward movement of the sliding block 32, it contacts a set of movable columns 37, causing it to unfold outward so that it can move up smoothly until the maintenance personnel reach the height. If a fall occurs, the sliding block 32 will also act on the movable columns 37, but it will be restricted by the limiting block 38, so that the sliding block 32 will stay in that position and not continue to move down.

[0045] This solution meets the needs of personnel for daily maintenance while ensuring the safety of maintenance operations, is easy to use, fulfills requirements, and improves the effectiveness of use.

[0046] Please see Figures 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0047] The filter mechanism includes positioning blocks 41. A set of positioning blocks 41 are damped and slidably connected to the opposite sides of the inner wall of the exhaust port 13. The inner side of the set of positioning blocks 41 is threaded with a first filter screen 42, a second filter screen 43 and a third filter screen 44 from the outside to the inside, and the mesh size is gradually increased.

[0048] The damped sliding connection between the positioning block 41 and the inner wall of the smoke exhaust port 13 allows for the movement of the installed first filter screen 42, second filter screen 43 and third filter screen 44, as well as the fixation of the structure after the movement. The dust contained in the smoke exhaust is filtered through the first filter screen 42, second filter screen 43 and third filter screen 44 with continuously increasing mesh size.

[0049] Working principle: During the actual smoke exhaust process, the first filter screen 42, the second filter screen 43 and the third filter screen 44 are pre-installed in the smoke exhaust port 13 by the positioning block 41, and the dust filtration of the exhaust gas is completed by the first filter screen 42, the second filter screen 43 and the third filter screen 44.

[0050] This solution not only filters dust from exhaust gases, but also allows for easy disassembly and replacement, saving time and effort. Furthermore, it employs different pore sizes for tiered dust isolation, which helps improve filtration efficiency and enhances overall performance.
