Description

Technical Field

[0002] Thermal power generation is a method of converting the heat energy generated by the combustion of combustibles into electrical energy through power generation devices. It is the main power generation method in my country. Among them, the thermal power boiler, as the core equipment of the thermal power plant, converts the chemical energy of the fuel into heat energy through combustion to heat and evaporate water, drive the turbine to rotate, and thus convert mechanical energy into electrical energy. When the thermal power boiler is burning, a large amount of flue gas will be generated. This flue gas can be discharged into the atmosphere from the flue of the thermal power boiler. During the discharge process, the smoke particles in the flue gas will adhere to the inner wall of the flue. Long-term accumulation will accumulate a thick layer of smoke on the inner wall of the flue, affecting the discharge of smoke from the flue. The flue needs to be cleaned regularly.

DETAILED DESCRIPTION

[0022] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0023] like Figure 1-6 As shown, the present invention provides a technical solution: a flue cleaning device for a thermal power boiler, comprising a fixed base 1, with mounting side plates 2 symmetrically fixedly installed on both sides of the fixed base 1, damping slide grooves 201 symmetrically arranged at both ends of the bottom of one side of the mounting side plate 2, and a damping slide plate 202 slidably installed inside the damping slide groove 201. Because the damping slide groove 201 and the damping slide plate 202 are provided, when the damping slide plate 202 slides inside the damping slide groove 201, the elastic potential energy of the damping spring 204 is consumed, thereby achieving buffering and shock reduction of the mounting side plate 2;

[0024] A clamping rod 203 is fixedly installed on one side of the damping slide plate 202, and one end of the clamping rod 203 passes through the damping slide groove 201 and extends to the outside of the mounting side plate 2. The clamping rod 203 is fixedly connected to the surface of the fixed base 1. A shock-absorbing spring 204 is provided on the surface of the clamping rod 203 located on the outside of the mounting side plate 2. By providing the shock-absorbing spring 204, the mounting side plate 2 is pushed in a direction away from the fixed base 1 under the rebound action of the shock-absorbing spring 204, so that the mounting side plate 2 drives the moving mechanism 3 to move, so that the moving wheel 304 can be close to the inner wall of the flue.

[0025] A rectangular groove 205 is provided on the top of the side of the mounting side plate 2 away from the fixed base 1, and limiting sliding grooves 206 are symmetrically provided on both sides of the inner wall of the rectangular groove 205. A moving mechanism 3 is respectively provided on the side of the two sets of mounting side plates 2 away from the fixed base 1. The moving mechanism 3 includes a mounting frame 301, and limiting rollers 302 are symmetrically fixedly installed on both sides of the mounting frame 301, and the positions of the limiting rollers 302 and the limiting sliding grooves 206 correspond to each other. Because the limiting sliding grooves 206 and the limiting rollers 302 are provided, when the mounting frame 301 is inserted into the rectangular groove 205, the limiting rollers 302 are inserted into the corresponding limiting sliding grooves 206, ensuring that there is no misalignment when the mounting frame 301 is inserted into the rectangular groove 205, and at the same time, the friction between the mounting frame 301 and the inner wall of the rectangular groove 205 is reduced, so that the mounting frame 301 is convenient to insert or remove from the rectangular groove 205;

[0026] A moving motor 303 is fixedly installed on one side inside the mounting frame 301, and a moving wheel 304 is provided at the output end of the moving motor 303. By providing the moving wheel 304, when the moving wheel 304 is pressed against the inner wall of the flue, the moving motor 303 is started to control the moving wheel 304 to rotate, thereby controlling the fixed base 1 to move inside the flue.

[0027] A trapezoidal slot 207 is provided at the top of one side of the inner wall of the rectangular slot 205. A mounting plate 4 is provided on the top surface of the moving mechanism 3 located on the inner side of the mounting side plate 2. A mounting slide 401 is symmetrically provided on one side of the inner wall of the mounting plate 4. A limit plate 402 is slidably installed inside the mounting slide 401. A fixing rod 403 is fixedly installed on one side of the limit plate 402. One end of the two sets of fixing rods 403 passes through the mounting slide 401 and is fixedly installed with a trapezoidal block 405. The position of the trapezoidal block 405 corresponds to the position of the trapezoidal slot 207. Since the trapezoidal slot 207 and the trapezoidal block 405 are provided, the mounting frame 301 and the mounting plate 4 are inserted into the rectangular slot 205 until the position of the trapezoidal block 405 corresponds to the position of the trapezoidal slot 207, so that the trapezoidal block 405 is inserted into the corresponding trapezoidal slot 207, thereby clamping and fixing the mounting frame 301 and the mounting plate 4 in the rectangular slot 205.

[0028] A fixing spring 404 is provided on the surface of the fixing rod 403 located on one side of the trapezoidal block 405, and a push plate 406 is fixedly installed on the top of the trapezoidal block 405, and the push plate 406 passes through the top of the mounting plate 4. By providing the fixing spring 404, the trapezoidal block 405 is pushed out of the mounting plate 4 and clamped into the corresponding trapezoidal slot 207 under the rebound action of the fixing spring 404;

[0029] A rotating groove 407 is provided at the top of the mounting plate 4 located between the two groups of mounting grooves 401, and a fixed top block 408 is rotatably installed inside the rotating groove 407, and a rubber clamping pad 409 is fixedly installed at one end of the fixed top block 408. Because of the fixed top block 408, after the trapezoidal clamping block 405 is inserted into the corresponding trapezoidal clamping groove 207, the rotating fixed top block 408 is rotated inside the rotating groove 407 until one end of the fixed top block 408 is tightly attached to one side of the trapezoidal clamping block 405, so that the rubber clamping pad 409 is squeezed and deformed between the trapezoidal clamping block 405 and the fixed top block 408, so that the fixed top block 408 can clamp and fix the trapezoidal clamping block 405, ensuring that the trapezoidal clamping block 405 will not arbitrarily escape from the trapezoidal clamping groove 207.

[0030] A rotating mechanism 5 is fixedly installed at the top of the fixed base 1 at the central position between the two groups of mounting side panels 2, and the rotating mechanism 5 includes a cleaning motor 501, a turntable 502 is fixedly installed at the output end of the cleaning motor 501, and six groups of support frames 503 are fixedly installed at equal angles on the surface of the turntable 502, and a mounting sleeve 504 is fixedly installed at one end of the six support frames 503 away from the turntable 502. By providing a cleaning motor 501, when the mounting sleeve 504 is put into the flue and the cleaning brush 7 is pressed against the inner wall of the flue, the cleaning motor 501 is controlled to rotate, thereby driving the mounting sleeve 504 to rotate inside the flue, so that the six groups of cleaning brushes 7 rotate and clean the inner wall of the flue.

[0031] Six groups of fixed plates 6 are fixedly installed at equal angles on the surface of the rotating mechanism 5, two groups of push rods 601 are slidably installed on one side of the fixed plate 6, and a clamping plate 602 is fixedly installed on one end of the two push rods 601. A T-shaped card slot 603 is provided on the side of the clamping plate 602 away from the fixed plate 6, and cleaning brushes 7 are respectively provided on the surfaces of the six groups of fixed plates 6 located outside the rotating mechanism 5. A T-shaped card strip 701 is fixedly installed on one side of the cleaning brush 7, and the T-shaped card strip 701 corresponds to the position of the T-shaped card slot 603 and has the same shape. Because the T-shaped card slot 603 and the T-shaped card strip 701 are provided, after the T-shaped card strip 701 is inserted into the corresponding T-shaped card slot 603, the T-shaped card strip 701 is clamped and fixed inside the T-shaped card slot 603, so that the cleaning brush 7 is clamped and fixed on one side of the clamping plate 602.

[0032] One end of the two groups of push rods 601 away from the pressing plate 602 passes through the fixing plate 6 and is fixedly installed with a connecting plate 604. A pressing spring 605 is provided on the surface of the push rod 601 located between the fixing plate 6 and the pressing plate 602. By providing the pressing spring 605, after the installation sleeve 504 is placed inside the flue, the pressing plate 602 and the cleaning brush 7 are pushed toward the inner wall of the flue under the rebound action of the pressing spring 605, so that the cleaning brush 7 can be closely attached to the inner wall of the flue;

[0033] An adjusting stud 606 is fixedly installed at the central position of one side of the fixing plate 6 away from the clamping plate 602, and one end of the adjusting stud 606 passes through the connecting plate 604 and is fixedly installed with a limiting end plate 607. An adjusting screw sleeve 608 is provided on the surface of the adjusting stud 606 between the connecting plate 604 and the limiting end plate 607. Because of the adjusting screw sleeve 608, the adjusting screw sleeve 608 is turned to rotate on the surface of the adjusting stud 606 to control the position of the adjusting screw sleeve 608 on the surface of the adjusting stud 606, thereby facilitating the control of the minimum distance between the clamping plate 602 and the fixing plate 6, and ensuring that the cleaning brush 7 will not fall off at will when it is close to the inner wall of the flue.

[0034] The working principle of the present invention is:

[0035] Insert the two sets of mounting brackets 301 into the rectangular groove 205 at the top of the mounting side plate 2 accordingly, so that the limiting rollers 302 on both sides of the mounting brackets 301 are inserted into the corresponding limiting slide grooves 206, and at the same time, the trapezoidal clamping block 405 on one side of the mounting plate 4 slides inside the rectangular groove 205, so that the trapezoidal clamping block 405 is pushed into the inside of the mounting plate 4, squeezing the fixing spring 404 to deform, until the trapezoidal clamping block 405 corresponds to the position of the trapezoidal clamping groove 207 on the inner wall of the rectangular groove 205, and then fix it. The spring 404 rebounds to push the trapezoidal block 405 out of the mounting plate 4 and into the corresponding trapezoidal slot 207, and the flip fixed top block 408 rotates from the inside of the rotating slot 407 to be close to the trapezoidal block 405, so that the rubber clamping pad 409 is squeezed and deformed on the surface of the trapezoidal block 405, and the trapezoidal block 405 is clamped and fixed to ensure that the trapezoidal block 405 is stuck in the trapezoidal slot 207 and will not fall out at will, thereby fixing the two sets of moving wheels 304 on one side of the mounting side plate 2;

[0036] The six groups of cleaning brushes 7 are clamped on the corresponding surfaces of the clamping plates 602, ensuring that the T-shaped clamping strips 701 are clamped into the corresponding T-shaped clamping grooves 603, so that the six groups of cleaning brushes 7 can be evenly clamped and fixed on the surface of the mounting sleeve 504, and after rotating the adjusting screw sleeve 608 away from the fixing plate 6, the mounting sleeve 504 is inserted into the boiler flue, so that the six groups of cleaning brushes 7 are closely attached to the inner wall of the boiler flue, and the clamping plate 602 is pushed close to the fixing plate 6, so that the clamping spring 605 is squeezed and deformed between the fixing plate 6 and the clamping plate 602, and the cleaning brush 7 can be closely attached to the inner wall of the boiler flue under the rebound effect of the clamping spring 605, and the adjusting screw sleeve 608 is turned close to the connecting plate 604, so as to limit the position of the connecting plate 604 moving on the surface of the adjusting stud 606, and at the same time limit the distance between the clamping plate 602 and the fixing plate 6, so as to ensure that the cleaning brush 7 will not separate from the inner wall of the boiler flue;

[0037] Start the cleaning motor 501 to drive the installation sleeve 504 to rotate on the inner wall of the boiler flue, drive the six groups of fixed plates 6 and the cleaning brush 7 to rotate on the inner wall of the boiler flue, so that the cleaning brush 7 can clean the inner wall of the boiler flue, and at the same time start the two groups of moving motors 303 to control the two groups of moving wheels 304 to rotate synchronously, so that the fixed base 1 can move inside the boiler flue, push the installation sleeve 504 to move on the inner wall of the boiler flue, so that the cleaning brush 7 can clean the inner wall of the boiler flue.
