A thermal control protection device for a thermal power plant and its use method

Abstract

The present invention discloses a protective device for thermal control of a thermal power plant and a method of use, specifically relating to the field of thermal control of a thermal power plant, comprising a protective frame, wherein two groups of working frames are fixedly connected inside the protective frame, and thermal control components are installed on the surface of the working frames. Since these thermal control components generate a large amount of heat when in use, the interior of the protective frame not only protects them but also dissipates heat to the internal working environment. The bottom of the protective frame is fixedly connected to a base, and a hollow protective frame is inserted into the interior of the base. The hollow protective frame surrounds power components such as a motor, and the aperture of the telescopic hole becomes smaller to prevent the dust introduced from escaping. As the insertion rod moves to the limit position, the guide block continues to rotate due to the sliding friction force of the corresponding rotating rod, and the folding frame is restored to its original position by the elastic force of the auxiliary spring, so that dust can easily enter from the telescopic hole, and the outer bending rod and the inner bending rod then perform intermittent circulation motion to achieve negative pressure generated inside the dust collection device.

Description

Technical Field

[0001] The present invention relates to the technical field of thermal control of thermal power plants, and more particularly to a protective device for thermal control of thermal power plants and a method for using the same. Background Art

[0002] The thermal control system of a thermal power plant is an important part of the automation or automatic control system of a thermal power plant. The function of the thermal control system is to control the parameters of various thermal processes. Automatic control includes the control of the main engine, auxiliary equipment and public systems. The function of the thermal control system is to control the parameters of various thermal processes, including temperature, pressure, flow, liquid level, etc., to keep them in the best state, so as to achieve safe and economical operation of the thermal power plant, and thus the thermal control system is in operation at all times.

[0003] In Chinese patent No. CN217608170U, a stepper motor is used to drive a scraper to clean the impurities adsorbed on the surface of the filter, thereby ensuring the permeability of the filter and improving the heat dissipation efficiency of the device. The centrifugal water pump can pump the cooling water in the water storage chamber into the condenser pipe, and the fan can blow the cold air around the condenser pipe into the protective device body, thereby cooling the protective device body, reducing the workload of the thermal control device, and improving the service life of the thermal control device.

[0004] However, the above solution has the following disadvantages:

[0005] 1. The scraper is used to clean the surface of the filter, but the filter is a mesh structure, and the inner walls of its telescopic holes are inside. The scraper cannot clean them, and the scraper may also scrape dust between the inner walls of the telescopic holes, where the dust accumulates and blocks the telescopic holes.

[0006] 2. Although the use of fans can reduce the surface temperature of the thermal control system of a thermal power plant, the filters are installed on both sides of the thermal control system of the power plant, causing dust to easily accumulate in the filters along with the air flow or pass through the filters and be absorbed by passing workers, which is not good for their health. Summary of the Invention

[0007] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a protective device for thermal control of a thermal power plant and a method of use. The telescopic hole is expanded or contracted by stretching the outer bending rod and the inner bending rod, so that a large amount of dust can be sucked into one side of the inner wall of the outer bending rod and the inner bending rod, and the aperture of the telescopic hole is reduced. The smaller the aperture of the telescopic hole, the less dust can be discharged. As the insertion rod moves to the limit position, the guide block continues to rotate due to the sliding friction force of the corresponding rotating rod, and the folding frame is restored to its original position by the elastic force of the auxiliary spring to solve the problems raised in the above-mentioned background technology.

A base plate is fixedly connected between the two groups of support rods, and the base plate slides up and down and is connected to the top of the central control protective frame. The annular frame is detachably connected to the upper end of the base plate.

[0011] As a further solution of the present invention, the telescopic hole device includes two groups of folding frames fixedly arranged on the inner side of the diamond mesh frame, and both ends of each folding frame are fixedly connected to the outer bending rod or the inner bending rod. A built-in rubber block is fixedly connected between the two groups of folding frames, and the telescopic hole frames are fixedly connected between the built-in rubber blocks. The telescopic hole is opened in the center of the telescopic hole frame, and an auxiliary spring is fixedly connected between the two groups of folding frames. A resisting block for pressing the built-in rubber block is fixedly provided on the auxiliary spring.

[0012] As a further solution of the present invention, a cavity is opened inside the built-in rubber block, and a vibration component is fixedly connected between the inner walls of the cavity. The vibration component includes: a fixing frame, an elastic rubber and two sets of spring rods fixedly connected between the fixing frame and the elastic rubber.

[0014] As a further solution of the present invention, a plurality of groups of electromagnetic rods are fixedly connected to the outer periphery of the base in a circular ring shape.

[0015] As a further solution of the present invention, the top of the rotating rod is fixedly connected to a collecting rack, the inner wall of the collecting rack is fixedly connected to multiple sets of snap-fit ​​racks, the top of the collecting rack is connected to a replaceable collecting net through the snap-fit ​​rack, and the outer surfaces of the collecting rack and the replaceable collecting net are provided with multiple sets of small holes.

[0016] As a further solution of the present invention, a control platform is fixedly connected to the outer side of the protective frame, and the control platform passes through the protective frame and is connected to the working frame.

[0017] As a further embodiment of the present invention, a method for using a thermal control protection device in a thermal power plant is characterized by comprising the following steps:

[0018] S1: The staff controls the work frame through the control platform. At this time, the cooling fan inside the protective frame dissipates heat from the work frame in the processing state;

[0019] S2: The heat dissipation airflow flows into the mesh structure. The motor acts as a drive. The motor drives the corresponding rotating rod to rotate through the rotation of the rotating rod. The corresponding rotating rod contacts the guide block, generating sliding friction between the two, which drives the guide block to slide along the slide rail. The guide block drives the lower slider to slide within the slide rail through the insertion rod. The insertion rod drives the auxiliary push rod to bend the diamond mesh frame. The bending of the diamond mesh frame drives the folding frame to stretch. The stretching of the folding frame controls the opening and closing of the telescopic holes. This cycle repeats, forming a negative pressure inside the dust collection device, completing the dust suction.

[0020] S3: The folding frame drives the built-in rubber block to squeeze the telescopic hole through the auxiliary spring, shrinking the aperture of the telescopic hole. The elastic rubber on the inner wall of the built-in rubber block is compressed by the extrusion of the telescopic hole. When the outer bending rod and the inner bending rod drive the folding frame to return to its original state, multiple groups of elastic rubber vibrate and squeeze the telescopic hole frame through the built-in rubber block, causing it to vibrate at the same frequency as the built-in rubber block, shaking off the dust on the inner wall of the telescopic hole.

[0021] S4: Heat is transferred to the outer and inner bending rods. The cooling pipe transfers the heat to the annular water tank through the internal coolant. The water pump then circulates the heat. At the same time, the hot air flow is guided by the rotating fan to the heat dissipation window.

[0022] S5: When the dust enters the replaceable collection net and the collection rack, the collection rack and the replaceable collection net are rotated by the rotating rod, and the rotating rod uses centrifugal force to rotate the dust into agglomerates.

[0023] Technical effects and advantages of the present invention:

[0024] 1. The telescopic hole expands or contracts due to the stretching of the outer bending rod and the inner bending rod, which facilitates the suction of a large amount of dust into one side of the inner wall of the outer bending rod and the inner bending rod, while reducing the aperture of the telescopic hole. The smaller the aperture of the telescopic hole, the smaller the diameter of the telescopic hole, which prevents the dust from entering from escaping. As the insertion rod moves to the limit position, the guide block continues to rotate due to the sliding friction of the corresponding rotating rod, and the folding frame returns to its original position due to the elastic force of the auxiliary spring, so that the dust can easily enter from the telescopic hole. The outer bending rod and the inner bending rod then perform intermittent cyclic motion, thereby preventing the dust from entering from escaping.

[0025] 2. The dust passes through the ring frame and the net of the outer bent rod. The motor acts as a drive, and the motor drives the rotary fan to rotate through the rotating rod. The rotary fan rotates to blow air toward the heat dissipation window. When the rotary fan stops rotating, the dust falls to the inside of the collection rack and the replaceable collection net or above the replaceable collection net by gravity, thereby achieving better dust collection and preventing the dust from being blown outside the equipment and inhaled by the staff, which is not good for their health.

[0026] 3. The elastic rubber vibrates due to the recovery of the airflow, and the spring rod also returns to its original position from the compressed state, increasing the vibration state of the elastic rubber. Multiple groups of elastic rubber vibrate and squeeze the telescopic hole frame through the built-in rubber block, causing it to vibrate at the same frequency as the built-in rubber block, shaking off the dust on the inner wall of the telescopic hole. Since the telescopic hole frame is intermittently opened by the outer bending rod and the inner bending rod, dust will not remain on the inner wall of the telescopic hole, thereby preventing the filter mesh from being blocked and affecting the heat dissipation and filtering effects of the filter mesh;

[0027] 4. The cooling pipe is arranged on the surface of the outer bending rod, which covers a larger area in the entire filtering mechanism, so the heat is transferred to the outer bending rod and the inner bending rod. The cooling pipe transfers the heat to the annular water tank through the internal coolant, and then uses a water pump to realize circulation. At the same time, the hot air flow is guided by the rotating fan to the heat dissipation window, avoiding the long-term appearance of hot air inside, thereby improving the heat dissipation effect of the device and avoiding heat accumulation.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See Figures 1 to 4 , a thermal control protection device for a thermal power plant according to an embodiment of the present invention comprises a protection frame 1, a working frame 3 fixedly connected to the inside of the protection frame 1 and a heat dissipation fan 2 for dissipating heat from the working frame 3, a heat dissipation window 12 is provided at the top of the protection frame 1, and a pressure gauge, a pressure transmitter, a differential pressure transmitter, a pressure calibrator, a thermal signal calibrator, an on-site thermometer, a thermal resistor, a thermocouple, a liquid level transmitter, a temperature transmitter, a pressure sensor, a liquid level transmitter, a liquid level meter and an intelligent digital display are installed inside the working frame 3; thermal control components are installed on the surface of the working frame 3, because these thermal control components will generate a lot of heat when in use, the inside of the protection frame 1 not only protects them but also dissipates heat to the working environment inside; a dust collection device 5 is fixedly provided between the bottom of the protection frame 1 and the heat dissipation window 12, and the dust collection device 5 comprises: a device fixedly connected to the protection frame 1 has a base 4 at the bottom and a hollow protective frame 33 inserted into the base 4; the top of the hollow protective frame 33 is slidably connected to a ring frame 17, and the top of the ring frame 17 is connected to a mesh structure 18. The mesh structure 18 is composed of a plurality of mutually hinged rhombus mesh frames 19. The rhombus mesh frames 19 are composed of two sets of outer bending rods 19a and inner bending rods 19b that are hinged to each other. A telescopic rod 20 is connected between two adjacent rhombus mesh frames 19. The dust collection device 5 is provided with a drive assembly 7 that drives the rhombus mesh frames 19 to bend, and a rotating fan 14 driven by the drive assembly 7; the hollow protective frame 33 surrounds the drive assembly 7 to prevent external dust from entering; the rhombus mesh frames 19 are provided with a telescopic hole device 8 with a telescopic hole 22. The telescopic hole device 8 opens and closes the telescopic hole 22 as the rhombus mesh frames 19 bend. The gaps between the mesh structure 18 outside the telescopic hole 22 are filled with heat dissipation glue 24.

[0042] See Figure 3 The specific way in which the annular frame 17 is slidably connected to the top of the hollow protective frame 33 is as follows: the top of the base 4 is fixedly connected to the auxiliary base frame 6, and two ends of the auxiliary base frame 6 are fixedly connected to two sets of retractable support rods 15. The base plate 16 is fixedly connected between the two sets of support rods 15, and the base plate 16 is slidably connected to the top of the central control protective frame 33 up and down, and the annular frame 17 is detachably connected to the upper end of the base plate 16.

[0043] During use, the driving assembly 7 drives the bending of the diamond mesh frame 19, thereby driving the opening and closing of the telescopic hole 22, and the remaining gaps are filled with the retractable heat dissipation glue 24, leaving only the telescopic hole 22 as an air channel. At the same time, according to the better heat dissipation characteristics of the heat dissipation glue 24, heat can also be conducted. Based on this, the rotating fan 14 is driven to blow air toward the heat dissipation window 12, taking away the air from the dust collection device 5. The opening and closing of the telescopic hole 22 creates a negative pressure in the dust collection device 5. When the telescopic hole 22 is opened, due to the negative pressure, the dust and hot air in the protective frame 1 flow into the telescopic hole 22, and the cycle repeats.

[0044] See for example Figure 4 as well as Figures 8 to 11 The driving assembly 7 includes: a slide rail frame 34 is opened at one end of the annular frame 17, one end of the slide rail frame 34 is fixedly connected to an elastic rope 38, one end of the elastic rope 38 is fixedly connected to a lower slider 37, the lower slider 37 is slidably connected to the inside of the slide rail frame 34, and an insertion rod 36 is inserted into the inside of the lower slider 37, and the inside of the lower slider 37 is fixedly connected to the insertion rod 36, one end of the insertion rod 36 is fixedly connected to an auxiliary push rod 35, the auxiliary push rod 35 is hinged to one end of the inner bending rod 19b, the insertion rod 36 passes through one end of the auxiliary push rod 35 and is rotatably connected to a guide block 41, and the outer surface of the rotating rod 39 is fixedly connected to a corresponding rotating rod 40, and the corresponding rotating rod 40 is fitted to one end of the guide block 41.

[0045] See Figure 5 and Figure 6 The telescopic hole device 8 includes two groups of folding frames 25 fixedly arranged on the inner side of the diamond mesh frame 19, and both ends of each folding frame 25 are fixedly connected to the outer bending rod 19a or the inner bending rod 19b. A built-in rubber block 23 is fixedly connected between the two groups of folding frames 25, and a telescopic hole frame 27 is fixedly connected between the built-in rubber blocks 23. The telescopic hole 22 is opened at the center of the telescopic hole frame 27. An auxiliary spring 26 is fixedly connected between the two groups of folding frames 25, and a block 26a for pressing the built-in rubber block 23 is fixedly provided on the auxiliary spring 26.

[0046] During driving, the rotation of the rotating rod 39 drives the corresponding rotating rod 40 to rotate. The corresponding rotating rod 40 contacts the guide block 41, and a sliding friction force is generated between the two to drive the guide block 41 to slide along the slide rail frame 34. The guide block 41 drives the lower slider 37 to slide in the slide rail frame 34 through the insertion rod 36. The elastic rope 38 limits and restores the lower slider 37, and the insertion rod 36 drives the auxiliary push rod 35 to pull the diamond mesh frame 19. The diamond mesh frame 19 drives the two groups of folding frames 25 to perform a stretching movement through the folding frame 25. At the same time, multiple groups of diamond mesh frames 19 are stretched through multiple groups of connected telescopic rods 20. At this time, the folding frame 25 is stretched with the built-in rubber block 23 by the auxiliary spring 26. At this time, the built-in rubber block 23 squeezes the telescopic hole 22 to be in a contracted state. As the insertion rod 36 moves to the limit position, the guide block 41 continues to rotate due to the sliding friction of the corresponding rotating rod 40. At this time, the elastic rope 38 pulls the insertion rod 36 back to its original position. At this time, the folding frame 25 is restored to its original position by the elastic force of the auxiliary spring 26, and the diamond mesh frame 19 then performs intermittent cyclic motion, the telescopic hole 22 opens and closes cyclically, and then a negative pressure is formed inside the mesh structure 18, which makes it easy for dust to flow into the telescopic hole 22, thereby greatly improving the dust collection effect.

[0047] See Figure 6 and Figure 7 Furthermore, a cavity 31 is opened inside the built-in rubber block 23, and a vibration component 28 is fixedly connected between the inner walls of the cavity 31. The vibration component 28 includes: a fixing frame 28b, an elastic rubber 28a, and two sets of spring rods 28c fixedly connected between the fixing frame 28b and the elastic rubber 28a.

[0048] See Figures 5 to 7 When the folding frame 25 is stretched by the outer bending rod 19a and the inner bending rod 19b, the folding frame 25 drives the built-in rubber block 23 to squeeze the telescopic hole 22 through the auxiliary spring 26. The aperture of the telescopic hole 22 is contracted, and the elastic rubber 28a on the inner wall of the built-in rubber block 23 is compressed by the extrusion of the telescopic hole 22. When the outer bending rod 19a and the inner bending rod 19b drive the folding frame 25 to return to its original state, the fixing frame 28b and the elastic rubber 28a return to their original state, and the rubber properties of the elastic rubber 28a are restored, causing vibration. The spring rod 28c also returns to its original position from the compressed state, increasing the vibration state of the elastic rubber 28a. Multiple groups of elastic rubber 28a vibrate and squeeze the telescopic hole frame 27 through the built-in rubber block 23, causing it to vibrate at the vibration frequency of the built-in rubber block 23, shaking off the dust on the inner wall of the telescopic hole 22. Since the telescopic hole frame 27 is intermittently opened by the outer bending rod 19a and the inner bending rod 19b, dust will not remain on the inner wall of the telescopic hole 22, thereby preventing the filter mesh from being blocked and affecting the heat dissipation and filtering effects of the filter mesh.

[0049] See Figures 1 to 4 An annular water tank 13 connected to the water pump is fixedly provided on the top of the mesh structure 18, a positioning ring frame 10 is fixedly provided on the upper circular open end of the protective frame 1, and the annular water tank 13 is inserted into the positioning ring frame 10. A cooling pipe 21 in a continuous state is fixedly connected to the outside of the mesh structure 18, and the cooling pipe 21 is connected to the annular water tank 13.

[0050] The cooling pipe 21 is a whole piece installed on the surface of the diamond mesh frame 19. It moves with the outer diamond mesh frame 19. The cooling pipe 21 is always connected to the annular water tank 13. As the wind blows the cooling fan 2, its heat is also brought into the position of the telescopic hole 22. The cooling pipe 21 is set on the surface of the diamond mesh frame 19. It covers a larger area in the entire filtering mechanism, so the heat is conducted to the diamond mesh frame 19. The cooling pipe 21 conducts the heat to the annular water tank 13 through the internal coolant, and then uses a water pump to circulate. At the same time, the hot air flow is guided by the rotating fan 14 to the heat dissipation window 12, avoiding the long-term appearance of hot air inside, thereby improving the heat dissipation effect of the device and avoiding heat accumulation.

[0051] See Figure 2 In one embodiment of the present invention, a control platform 11 is fixedly connected to the outside of the protective frame 1. The control platform 11 passes through the protective frame 1 and is connected to the working frame 3. A heat dissipation window 12 is provided at the top of the protective frame 1.

[0052] See Figure 8 , multiple groups of electromagnetic rods 42 are fixedly connected to the top of the base 4, and the multiple groups of electromagnetic rods 42 are arranged in a circular ring shape on the outer periphery of the base 4. The dust entering the hollow protective frame 33 is adsorbed by the multiple groups of electromagnetic rods 42 to prevent the motor 71 from being affected by the dust. The top of the rotating rod 39 is fixedly connected to the collecting frame 30, and the inner wall of the collecting frame 30 is fixedly connected to multiple groups of snap-fit ​​frames 9. The top of the collecting frame 30 is plugged with a replaceable collecting net 29 through the snap-fit ​​frame 9. The outer surfaces of the collecting frame 30 and the replaceable collecting net 29 are provided with multiple groups of small holes, which facilitate the outflow of the airflow of the rotating fan 14. When dust enters the interior of the replaceable collecting net 29 and the collecting frame 30, the collecting frame 30 and the replaceable collecting net 29 are rotated through the rotating rod 39, and the rotating rod 39 uses centrifugal force to rotate the dust into a ball. The staff collects the agglomerated dust by pulling out the replaceable collecting net 29.

[0053] A method for using a thermal control protection device for a thermal power plant, characterized by comprising the following steps:

[0054] S1: The staff controls the work frame 3 through the control platform 11. At this time, the cooling fan 2 inside the protective frame 1 cools the work frame 3 in the processing state;

[0055] S2: The heat dissipation airflow flows into the mesh structure 18, and the motor 71 acts as a drive. The motor 71 drives the corresponding rotating rod 40 to rotate through the rotating rod 39. The corresponding rotating rod 40 contacts the guide block 41, and a sliding friction force is generated between the two, which drives the guide block 41 to slide along the slide rail frame 34. The guide block 41 drives the lower slider 37 to slide in the slide rail frame 34 through the insertion rod 36. The insertion rod 36 drives the auxiliary push rod 35 to pull the diamond mesh frame 19 to bend. The bending of the diamond mesh frame 19 drives the folding frame 25 to stretch. The opening and closing of the telescopic hole 22 is controlled by the stretching of the folding frame 25. This cycle is repeated, and a negative pressure is formed inside the dust collection device 5 to complete the dust suction.

[0056] S3: The folding frame 25 drives the built-in rubber block 23 to squeeze the telescopic hole 22 through the auxiliary spring 26. The aperture of the telescopic hole 22 is reduced, and the elastic rubber 28a on the inner wall of the built-in rubber block 23 is compressed by the extrusion of the telescopic hole 22. When the outer bending rod 19a and the inner bending rod 19b drive the folding frame 25 to return to its original state, the multiple groups of elastic rubber 28a vibrate and squeeze the telescopic hole 22 through the built-in rubber block 23, causing it to vibrate at the same frequency as the built-in rubber block 23, shaking off the dust on the inner wall of the telescopic hole 22.

[0057] S4: Heat is transferred to the outer bending rod 19a and the inner bending rod 19b. The cooling pipe 21 transfers the heat to the annular water tank 13 through the internal coolant. The water pump is then used to circulate the heat. At the same time, the hot air flow is guided by the rotating fan 14 to the heat dissipation window 12.

[0058] S5: When the dust enters the replaceable collecting net 29 and the collecting rack 30, the collecting rack 30 and the replaceable collecting net 29 are rotated by the rotating rod 39, and the rotating rod 39 uses centrifugal force to rotate the dust into agglomerates.
