Description

Technical Field

[0001] This utility model relates to the field of thermal power plant boiler technology, and in particular to a rapid cleaning device for thermal power plant boilers. Background Technology

[0002] A thermal power plant boiler is an energy conversion device. The energy input to the boiler includes the chemical energy of the fuel and electrical energy. The boiler outputs steam with a certain amount of thermal energy, which is converted into mechanical energy through a steam power device, or further converted into electrical energy through a generator. After prolonged use, existing boilers accumulate a large amount of dust from fuel combustion on their inner walls, forming a dust layer of a certain thickness. This reduces fuel utilization and poses safety hazards, necessitating the use of cleaning equipment to clean the boiler's inner walls.

[0003] Chinese patent document CN217057567U discloses a rapid cleaning device for thermal power plant boilers, which includes a movable disc, a rotating disc, and a rotating assembly disposed between the rotating disc and the movable disc for driving the rotating disc to rotate. The movable disc has a rotating disc on its top, a control panel on its front, and a connecting rod connected to its bottom, with a handle connected to the bottom of the connecting rod. The rotating assembly includes a motor box, a motor, and a rotating rod. The motor box is connected to the top of the movable disc, and the motor is housed inside the motor box. The rotating rod is driven by the top of the motor. This rapid cleaning device for thermal power plant boilers utilizes a combination of movable blocks, springs, slots, locking blocks, and brushes to ensure the brushes can adhere to the inner wall of the thermal power plant boiler, thus guaranteeing the cleaning effect. Furthermore, the combination of movable blocks, telescopic springs, limiting blocks, and movable wheels facilitates the movement of the brushes.

[0004] The existing technology has the following problems:

[0005] Although the movable block in the aforementioned device is connected to a spring, its cleaning range is limited and it cannot drive the brush to adapt to boilers of different sizes. Secondly, the rotating disc in the aforementioned device can only rotate via the motor box. When it is necessary to change the cleaning position, the entire device needs to be lifted or moved manually, which is laborious, easily increases labor costs, and has low practicality.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-5 As shown, a rapid cleaning device for a thermal power plant boiler includes a fixed plate 1. A central control module 11 is fixedly installed on the front of the outer wall of the fixed plate 1. A position adjustment component 2 is movably connected to the middle of the upper end of the fixed plate 1. A cleaning component 3 is fixedly installed on the top of the position adjustment component 2.

[0029] The position adjustment assembly 2 includes a rotating sleeve 21 with an open top. The lower end of the rotating sleeve 21 is rotatably connected to the middle of the upper end of the fixed plate 1. The inner wall of the rotating sleeve 21 is slidably connected to the left and right sides of a movable frame 22 with an open bottom. The bottom of the outer wall of the rotating sleeve 21 is movably connected to a rotating mechanism 23. An electric push rod 24 is fixedly installed on the bottom of the inner wall of the rotating sleeve 21. The output end of the electric push rod 24 is fixedly connected to the bottom of the inner wall of the movable frame 22.

[0030] The cleaning assembly 3 includes a protective cover 31. The lower end of the protective cover 31 is fixedly connected to the upper end of the movable frame 22. An installation cylinder 32 is fixedly installed on the upper end of the protective cover 31. A reverse double threaded rod 33 that passes through the bottom of the installation cylinder 32 is rotatably connected to the top of the inner wall of the installation cylinder 32. A motor 34 is fixedly installed in the middle of the lower end of the installation cylinder 32. The motor 34 is located inside the protective cover 31. The output end of the motor 34 is fixedly connected to the lower end of the reverse double threaded rod 33. Movable discs 35 are threadedly connected to the upper and lower parts of the outer wall of the reverse double threaded rod 33. Four adjusting rods 36 arranged in a ring are rotatably connected to the edges of the two movable discs 35. The eight adjacent adjusting rods 36 are symmetrically arranged. The ends of the eight adjacent adjusting rods 36 away from the reverse double threaded rod 33 are rotatably connected to a limiting frame 37 with an integral hollow structure. The outer wall of the installation cylinder 32 has four moving grooves that are arranged in a ring and match the four limiting frames 37. A brush 38 can be detachably connected to the side of the four limiting frames 37 away from the axis of the installation cylinder 32.

[0031] The position adjustment component 2 can drive the mounting cylinder 32 to rotate and move up and down, eliminating the need for manual movement of the brushes to clean the boiler's inner wall. When the mounting cylinder 32 extends into the boiler, the rotating mechanism 23 drives the mounting cylinder 32 to rotate, which in turn drives the four brushes 38 to rotate and brush the boiler's inner wall. When the cleaning position needs to be changed, the electric actuator 24 is activated, and its output end drives the moving frame 22 to move within the rotating sleeve 21. The moving frame 22 then drives the mounting cylinder 32 to move up and down, allowing the brushing position of the four brushes 38 to be changed quickly without manual assistance, resulting in a high degree of automation and cost savings. The cleaning component 3 can clean boilers of different sizes. When the motor 34 is started, it drives the reverse double threaded rod 33 to rotate. The two moving discs 35 are brought together / separated by being threadedly connected to the reverse double threaded rod 33, causing one end of each of the eight adjacent adjusting rods 36 to rotate around the corresponding fixed shaft 39, while the other end pushes / pulls the corresponding limiting frame 37 out of / into the mounting cylinder 32, thereby adjusting the distance between the four brushes 38 and the boiler's inner wall, improving the device's applicability.

[0032] like Figure 4 As shown, the rotating mechanism 23 includes a gear 231, the inner wall of which is fixedly connected to the bottom of the outer wall of the rotating sleeve 21. A drive motor 232 is fixedly installed at the front of the upper end of the fixed disk 1. A gear 233 is fixedly sleeved at the output end of the drive motor 232. The outer surface of the gear 231 meshes with the outer surface of the gear 233.

[0033] The rotating mechanism 23 can drive four brushes 38 to rotate and scrub the inner wall of the boiler. When the drive motor 232 starts, its output end drives the gear 233 to rotate. The gear 231 drives the rotating sleeve 21 to rotate by meshing with the gear 233, so that the mounting cylinder 32 can drive the four brushes 38 to rotate.

[0034] like Figure 1 , Figure 4 and Figure 6 As shown, the inner wall of the rotating sleeve 21 is provided with sliding grooves 25 on both the left and right sides, and the outer wall of the moving frame 22 is fixedly installed with two matching sliding grooves 25 limiting strips 26 on both the left and right sides.

[0035] The sliding groove 25 and the limiting strip 26 can prevent the moving frame 22 from slipping and failing to rotate when the rotating sleeve 21 rotates, and the two sliding grooves 25 also have a limiting effect on the movement of the moving frame 22.

[0036] like Figure 3 and Figure 4 As shown, both the rotating sleeve 21 and the moving frame 22 are cylindrical structures.

[0037] like Figure 5As shown, each of the two movable disks 35 has four mounting slots arranged in a ring on its sidewalls. Each of the eight mounting slots has a fixed shaft 39 fixedly installed on its inner wall. The ends of the eight adjacent adjusting rods 36 that are far apart from each other are rotatably connected to the middle of the outer wall of the eight fixed shafts 39.

[0038] When the two movable disks 35 move in opposite directions, the eight adjusting rods 36 rotate around the eight fixed axes 39.

[0039] like Figure 6 As shown, four elastic telescopic rods 12 arranged in a ring are fixedly installed on the top of the outer wall of the fixed disk 1. Each of the four elastic telescopic rods 12 is rotatably connected to a roller 13 at one end away from the axis of the fixed disk 1.

[0040] The four elastic telescopic rods 12 and rollers 13 ensure the overall stability of the device when placed inside the boiler wall, serving as a limiting function. The elastic telescopic rods 12 are mainly composed of telescopic rods and springs, providing a cushioning effect.

[0041] like Figure 1 As shown, a handle is fixedly installed at the lower end of the fixed plate 1.

[0042] The handle makes it easy for users to lift the entire device.

[0043] The working principle of this utility model is as follows: When in use, the entire device is stably slid into the boiler through four rollers 13. The four elastic telescopic rods 12 play a buffering role to avoid damage to the inner wall of the boiler and can also adapt to boilers of different sizes.

[0044] The central control module 11 is used to control the operation of the entire cleaning device, including starting and stopping the motor 34, electric push rod 24, and drive motor 232, as well as adjusting their operating parameters. When the motor 34 starts, its output end can drive the reverse double threaded rod 33 to rotate. The two moving discs 35 are brought together / separated by being threadedly connected to the reverse double threaded rod 33, thereby causing one end of the eight adjacent adjusting rods 36 to rotate around the corresponding fixed shaft 39, and the other end to push out / pull in the corresponding limiting frame 37 into the mounting cylinder 32, thereby adjusting the distance between the four brushes 38 and the inner wall of the boiler. The four moving slots limit the movement of the four limiting frames 37. Then, the rotating mechanism 23 is started, which drives the mounting cylinder 32 to rotate. The mounting cylinder 32 drives the four brushes 38 to rotate and brush the inner wall of the boiler. When it is necessary to change the cleaning position, the electric push rod 24 is started. Its output end drives the moving frame 22 to move inside the rotating sleeve 21. The moving frame 22 drives the mounting cylinder 32 to move up and down, so that the brushing position of the four brushes 38 can be changed quickly without manual assistance. It has a high degree of automation and can save costs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
