Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a boiler surface cleaning device. Background Technology

[0002] Gas-fired boilers include gas-fired hot water boilers, gas-fired steam boilers, etc. A Chinese utility model patent, authorized publication number "CN211952807U", discloses a surface cleaning device for gas-fired boilers. The device includes a base plate, a vertical plate on the top outer wall of the base plate, and a limit opening on one side of the outer wall of the vertical plate. A motor housing is slidably connected to the inner wall of the limit opening. A fixing plate is provided on one side of the outer wall of the vertical plate, and a threaded hole is provided on the top outer wall of the fixing plate. A threaded rod is threadedly connected to the inner wall of the threaded hole. An adjusting wheel is provided on the top outer wall of the threaded rod, and a turntable is welded to the bottom outer wall of the threaded rod. A fixing cover is welded to the top outer wall of the motor housing, and the inner wall of the fixing cover is rotatably connected to the outer wall of the turntable. A motor is bolted to the inner wall of the motor housing, and a rotating rod is provided at one end of the output shaft of the motor. This utility model can clean the combustion chambers of boilers of different diameters, offering greater flexibility and convenience for cleaning gas-fired boilers of different heights, resulting in better cleaning performance.

[0003] The above technical solution uses a limiting port, adjusting wheel, turntable, and fixed cover. Rotating the adjusting wheel drives the threaded rod to rotate, which in turn drives the turntable to move up and down. The turntable is fixed in the fixed cover, allowing the motor housing to slide within the limiting port. This facilitates adjusting the rotating rod to a position level with the combustion chamber of the gas boiler. However, the above technical solution still has certain drawbacks. For example, while rotating the adjusting wheel can drive the threaded rod to rotate, making it easy to adjust the rotating rod to a position level with the combustion chamber of the gas boiler, the cleaning mechanism requires maintenance and repair after long-term use. This requires workers to use special tools and multiple people to disassemble it, which is complicated and difficult, thus reducing the practicality of the equipment and increasing the workload of the workers.

The device can drive the threaded rod to rotate by rotating the adjusting wheel, so that the rotating rod can be easily adjusted to a position that is level with the combustion chamber of the gas boiler. However, when the cleaning mechanism needs to be maintained and repaired after long-term use, it requires workers to use special tools and multiple people to disassemble it. This operation is complicated and difficult, which reduces the practicality of the equipment and increases the workload of the workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a boiler surface cleaning device, comprising a base, a support column, and a sliding mounting seat, wherein a limit component is provided on the sliding mounting seat;

The cleaning mechanism consists of a cleaning brush and a fixed seat.

[0008] In this configuration, the ends of the two limiting blocks near the second limiting block grooves both slide into the interior of the groove and are respectively slidably connected to the interior of the corresponding second limiting block grooves.

[0009] Preferably, the interiors of the two first limiting block slots are respectively connected to the interiors of the corresponding protective shells, and the ends of the two adjusting threaded rods near the limiting blocks are respectively fixedly connected to the outer walls of the corresponding limiting blocks;

[0010] Among them, the ends of the two rotating threaded rod sleeves near the limiting block both extend into the interior of the first limiting block groove, and the ends of the two adjusting threaded rods away from the limiting block are respectively connected to the internal threads of the corresponding rotating threaded rod sleeves.

[0011] Preferably, the outer wall of the support column has two first T-shaped block grooves, and the two T-shaped blocks on the outer wall of the sliding mounting seat are slidably connected to the interior of the corresponding first T-shaped block grooves;

[0012] The outer wall of the support column has a groove with a threaded rod rotatably connected inside.

[0013] Preferably, the outer wall of the protrusion on the sliding mounting base is slidably connected to the outer wall of the support column through a groove and is threadedly connected to the outer wall of the threaded rod.

[0014] The first electric motor is fixedly installed on the upper surface of the support column.

[0015] Preferably, the output end of the first motor extends rotatably into the groove on the outer wall of the support column and is fixedly connected to one end of the threaded rod, and the support column is fixedly installed on the upper surface of the base;

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This boiler surface cleaning device uses a rotating threaded rod sleeve on one side of the protective shell in the limiting assembly to rotate in the opposite direction. This causes the adjusting threaded rod to drive the limiting block to overcome friction and slide into the first limiting block groove, allowing the limiting block to exit from the second limiting block groove. This releases the fixed connection between the cleaning mechanism and the connecting seat. At this point, the cleaning mechanism can be slid out along the slide groove to disassemble it and clean or replace the cleaning brush.

[0030] A limit component is provided on the sliding mounting base 5;

[0031] The limiting assembly includes a cleaning mechanism 7, a connecting seat 8, a second motor 11, and two protective shells 9. The connecting seat 8 is fixedly installed on the output end of the second motor 11, which is fixedly installed inside a groove on one side of the sliding mounting seat 5. A sliding groove 15 is formed on the outer wall of the connecting seat 8 away from the second motor 11. The outer wall of the fixed seat on the cleaning mechanism 7 is slidably connected to the inside of the sliding groove 15. Four second T-shaped block grooves 16 are formed on the inner wall of the sliding groove 15. The four T-shaped blocks on the outer wall of the fixed seat on the cleaning mechanism 7 are slidably connected to the inside of the corresponding second T-shaped block grooves 16. The cleaning mechanism 7 consists of a cleaning brush and a fixed seat. First limiting block grooves 14 are formed on both sides of the inner wall of the sliding groove 15. Limiting blocks 13 are slidably connected inside the two first limiting block grooves 14. Second limiting blocks are formed on both sides of the outer wall of the fixed seat on the cleaning mechanism 7. The groove 17, the two limiting blocks 13 near the end of the second limiting block groove 17 are slidably extended into the interior of the slide groove 15 and are slidably connected to the interior of the corresponding second limiting block groove 17 respectively. The two protective shells 9 are fixedly installed on the corresponding outer walls of the connecting seat 8. The interiors of the two first limiting block grooves 14 are respectively connected to the interiors of the corresponding protective shells 9. The outer walls of one side of the two protective shells 9 are rotatably connected with rotating threaded rod sleeves 10. The interiors of the two first limiting block grooves 14 are each provided with adjusting threaded rods 12. The ends of the two adjusting threaded rods 12 near the limiting block 13 are respectively fixedly connected to the outer walls of the corresponding limiting block 13. The ends of the two rotating threaded rod sleeves 10 near the limiting block 13 are rotatably extended into the interior of the first limiting block groove 14. The ends of the two adjusting threaded rods 12 away from the limiting block 13 are respectively threadedly connected to the interior of the corresponding rotating threaded rod sleeves 10.

[0032] The support column 2 has two first T-shaped block grooves 6 on its outer wall. The two T-shaped blocks on the outer wall of the sliding mounting seat 5 are slidably connected to the interior of the corresponding first T-shaped block grooves 6. The support column 2 has a threaded rod 4 rotatably connected inside the groove on its outer wall. The outer wall of the protrusion on the sliding mounting seat 5 is slidably connected to the groove on the outer wall of the support column 2 and threadedly connected to the outer wall of the threaded rod 4. The support column 2 is fixedly mounted on its upper surface. The output end of the first motor 3 extends rotatably into the groove on the outer wall of the support column 2 and is fixedly connected to one end of the threaded rod 4. The support column 2 is fixedly mounted on the upper surface of the base 1. The first motor 3 is electrically connected to the battery pack installed inside the groove on the base 1. The second motor 11 is electrically connected to the battery pack installed inside the groove on the base 1.

[0033] Furthermore, when using this device, firstly, based on the height position of the boiler surface, the first motor 3 is started. The output end of the first motor 3 drives the threaded rod 4 to rotate. Since the outer wall of the protrusion on the sliding mounting seat 5 is threadedly connected to the threaded rod 4, the sliding mounting seat 5 moves up and down along the support column 2 when the threaded rod 4 rotates. By controlling the rotation direction and time of the first motor 3, the sliding mounting seat 5 is adjusted to a suitable height position so that the cleaning mechanism 7 can accurately reach the area to be cleaned on the boiler surface. Then, the fixed seat of the cleaning mechanism 7 is aligned with the sliding groove 15 of the connecting seat 8, and the cleaning mechanism 7 is pushed so that the fixed seat... The fixed seat slides along the slide groove 15, and at the same time, the four T-shaped blocks on the fixed seat slide into the corresponding second T-shaped block grooves 16, realizing the initial positioning of the cleaning mechanism 7. The rotating threaded rod sleeve 10 on one side of the protective shell 9 is rotated. The rotating threaded rod sleeve 10 is threadedly connected to the adjusting threaded rod 12. As the rotating threaded rod sleeve 10 rotates, the adjusting threaded rod 12 moves in the first limiting block groove 14. The adjusting threaded rod 12 drives the limiting block 13 to slide in the first limiting block groove 14. When the limiting block 13 slides to a certain position, its end near the second limiting block groove 17 slides into the second limiting block groove of the fixed seat of the cleaning mechanism 7. Within 17, the rotation of the threaded sleeve 10 stops, and the limiting block 13 is firmly engaged in the second limiting block groove 17, achieving a fixed connection between the cleaning mechanism 7 and the connecting seat 8. After the cleaning mechanism 7 is installed and fixed, the second motor 11 is started. The output end of the second motor 11 drives the connecting seat 8 to rotate, and the connecting seat 8 in turn drives the cleaning mechanism 7 to rotate. The cleaning brush rotates with the cleaning mechanism 7, contacts the boiler surface and generates friction. Through continuous rotation, the cleaning brush removes dirt from the boiler surface. During the cleaning process, because the cleaning mechanism 7 is firmly fixed to the connecting seat 8 by the limiting block 13, and The sliding mounting base 5 is stably mounted on the support column 2 via the threaded rod 4, ensuring the stability and cleaning effect of the cleaning mechanism 7 during rotation. Then, when it is necessary to clean or replace the cleaning mechanism 7, the rotating threaded rod sleeve 10 on one side of the protective shell 9 is rotated in the opposite direction, causing the adjusting threaded rod 12 to drive the limiting block 13 to overcome the friction and slide into the first limiting block groove 14, so that the limiting block 13 exits from the second limiting block groove 17, releasing the fixed connection between the cleaning mechanism 7 and the connecting base 8. At this time, the cleaning mechanism 7 can be slid out along the slide groove 15, and the cleaning mechanism 7 can be disassembled to clean or replace the cleaning brush.

[0034] By rotating the threaded sleeve 10 on one side of the protective shell 9 in the reverse rotation of the limiting assembly, the adjusting threaded rod 12 drives the limiting block 13 to overcome the friction and slide into the first limiting block groove 14, so that the limiting block 13 exits from the second limiting block groove 17, and the fixed connection between the cleaning mechanism 7 and the connecting seat 8 is released. At this time, the cleaning mechanism 7 can be slid out along the slide groove 15, and the cleaning mechanism 7 can be disassembled to clean or replace the cleaning brush. This disassembly of the cleaning mechanism 7 is simple and quick, effectively reducing the workload of the staff while improving the maintenance and repair efficiency of the cleaning mechanism 7.
