Description

Technical Field

[0001] The invention relates to the technical field of power station units, and in particular to a power station unit with dust-proof and heat-dissipating functions. Background Art

[0002] The machine room of a power station is used to install and store generator equipment. Usually, the power equipment units of a power station are installed in the machine room to facilitate maintenance and management. The installation of power equipment in the machine room can ensure the safety of the power equipment.

[0003] In order to dissipate heat, existing power station machine rooms usually install cooling fans at the heat dissipation vents of the machine room to blow air inside, thereby facilitating the heat dissipation of the power equipment in the machine room. In order to prevent external dust from entering the machine room through the heat dissipation vents and causing short circuit damage to the power equipment, filters are usually installed at the heat dissipation vents to intercept dust. After long-term use, the dust will block the filter, causing the ventilation performance to decrease, thereby affecting the heat dissipation inside the machine room. Therefore, the filter needs to be manually disassembled for cleaning and replacement, which is troublesome, time-consuming and labor-intensive.

[0004] Based on this, we propose a power station unit with dust-proof and heat-dissipating functions. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and to propose a power station unit with dust-proof and heat-dissipating functions.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A power station unit with dust-proof and heat-dissipating functions, comprising a machine room and a generator set arranged inside the machine room, wherein a dust-proof mechanism is installed on the machine room; The dust prevention mechanism comprises a mounting base fixedly connected to the side wall of the machine room, a dust filter cartridge is fixed to the side wall of the mounting base, an air inlet is opened at the lower end of the dust filter cartridge, an air inlet is fixed to the upper end of the mounting base, the air inlet fan is connected to the machine room through an air inlet pipe, the air inlet fan is connected to the dust filter cartridge through an exhaust pipe, a filter screen is fixed to the inner wall of the dust filter cartridge, and a cleaning mechanism is installed on the dust filter cartridge; The cleaning mechanism includes a driving box fixed to the inner wall of the dust filter cartridge, the side wall of the driving box is rotatably connected to a rotating shaft, a plurality of cleaning rods are symmetrically fixed to the side wall of the rotating shaft, a plurality of cleaning rods are fixed with bristles at the other ends, one end of the rotating shaft extends into the driving box and a plurality of impellers are fixed, the air inlet pipe is connected to the driving box through a connecting pipe a, an electromagnetic valve is installed on the inner wall of the connecting pipe a, a wind shield is rotatably connected to the inner wall of the dust filter cartridge, a first spring is commonly fixed between the upper end of the wind shield and the inner wall of the dust filter cartridge, an arc-shaped groove is opened on the inner wall of the dust filter cartridge, a conductive strip is fixed to the inner wall of the arc-shaped groove, a conductive block matching the conductive strip is fixed to the side wall of the wind shield, and the electromagnetic valve is electrically connected to the conductive strip through a wire.

[0007] Furthermore, the cleaning mechanism also includes a slide cylinder fixed on the inner wall of the dust filter cylinder, the inner wall of the slide cylinder is slidably connected with a slide plug, the upper end of the slide plug is fixedly connected with a push rod, the upper end of the push rod is arranged to pass through the upper end of the slide cylinder, a second spring is fixedly connected to the top of the slide cylinder, the lower end of the second spring is fixedly connected to the slide plug, one end of the rotating shaft passes through the side wall of the slide cylinder and extends into the slide cylinder, the side wall of the rotating shaft located in the slide cylinder is fixedly connected with a cam, and the cam is abutted against the lower end of the slide plug.

[0008] Furthermore, a plurality of dust suction holes are provided on the inner wall of the driving box, a dust collecting box is fixedly connected to the side wall of the dust filter cylinder, and the driving box is connected to the dust collecting box through a connecting pipe b.

[0009] Furthermore, a plurality of semiconductor cooling plates are symmetrically embedded on the inner wall of the dust filter cylinder, and the plurality of semiconductor cooling plates are electrically connected to the conductive strips through wires.

[0010] Furthermore, the filter screen is in a semi-cylindrical shape and is made of elastic material.

[0011] Furthermore, a safety door is installed on the side wall of the machine room, and a ventilation duct is arranged at the upper end of the machine room.

[0012] The present invention has the following advantages: 1. By setting up a cleaning mechanism, when the filter is not blocked by dust and the ventilation is smooth, the wind shield will be blown upwards under the action of the airflow, so that the conductive block is disconnected from the conductive strip. After the filter has been used for a long time, more dust and impurities adhere to the surface, causing the ventilation performance of the filter to deteriorate, and then the airflow received by the wind shield will decrease and rotate downward until the conductive block is in contact with the conductive strip. At this time, the solenoid valve is energized and opened, and the airflow will enter the drive box, blowing the impeller to rotate, and then driving the shaft to rotate, so that the cleaning rod drives the bristles to clean the surface of the filter, so that the degree of blockage of the filter can be automatically judged according to the size of the airflow, and cleaning is automatically performed. Compared with the existing manual disassembly and cleaning, it is more convenient and intelligent, and there is no need for manual attention to the degree of blockage of the filter at all times, which greatly reduces the labor intensity of workers.

[0013] 2. By setting up a cleaning mechanism, the rotation of the shaft will synchronously drive the cam to rotate, and then under the action of the cam and the second spring, the sliding plug will drive the push rod to continuously knock on the filter, causing the filter to vibrate. Under the action of the vibration, the dust on the filter is easier to be cleaned off, and the cleaning effect is better.

[0014] 3. By setting the dust suction holes, connecting pipe b and dust collecting box, when the filter is cleaned, the airflow will flow rapidly from top to bottom in the drive box. According to Bernoulli's theorem, when the airflow flows at equal heights, the faster the flow speed, the smaller the pressure generated, and the stronger the suction force generated. Therefore, the dust swept off the filter will be sucked into the drive box through multiple dust suction holes, and then the dust will enter the dust collecting box through the connecting pipe b together with the airflow to prevent the swept dust from flying into the air again and polluting the environment.

[0015] 4. By setting up a semiconductor refrigeration sheet, when the filter is severely clogged and cleaned, the air flow entering the computer room will be reduced, and the heat dissipation effect will decrease. During cleaning, the semiconductor refrigeration sheet will be powered on and started to pre-cool the air flow entering the computer room, so that the temperature of the air flow entering the computer room will decrease. In this way, even if the incoming air flow is reduced, a good cooling and heat dissipation effect can still be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Reference Figure 1-6 A power station unit with dust-proof and heat-dissipating functions comprises a machine room 1 and a generator set arranged therein, a safety door 29 is installed on the side wall of the machine room 1, a ventilation pipe 30 is arranged at the upper end of the machine room 1, and a dust-proof mechanism is installed on the machine room 1; The dust prevention mechanism includes a mounting base 2 fixedly connected to the side wall of the machine room 1, a dust filter cylinder 3 is fixed to the side wall of the mounting base 2, an air inlet 301 is opened at the lower end of the dust filter cylinder 3, an air inlet fan 4 is fixed to the upper end of the mounting base 2, the air inlet fan 4 is connected to the machine room 1 through an air inlet pipe 5, and the air inlet fan 4 is connected to the dust filter cylinder 3 through an exhaust pipe 6, a filter screen 7 is fixed to the inner wall of the dust filter cylinder 3, the filter screen 7 is in a semi-cylindrical shape, and the filter screen 7 is made of elastic material, so that the filter screen 7 has a certain elasticity, when the filter screen 7 is knocked, the filter screen 7 can vibrate, and a cleaning mechanism is installed on the dust filter cylinder 3; Furthermore, by starting the air intake fan 4, the cold air from the outside will be drawn into the dust filter cartridge 3 through the air inlet 301, and then the cold air in the dust filter cartridge 3 will enter the interior of the computer room 1 through the exhaust duct 6 and the air inlet duct 5, so as to cool down the power equipment in the computer room 1 and prevent the power equipment from being damaged by overheating. When the cold air flows through the filter 7, the dust and impurities contained in the cold air will be retained by the filter 7 to prevent them from entering the computer room 1 and causing damage to the power equipment.

[0020] The cleaning mechanism includes a driving box 8 fixed to the inner wall of the dust filter cartridge 3, the driving box 8 is located below the filter screen 7, the side wall of the driving box 8 is rotatably connected with a rotating shaft 9, a plurality of cleaning rods 10 are symmetrically fixed to the side wall of the rotating shaft 9, the other ends of the plurality of cleaning rods 10 are fixed with bristles 11, the bristles 11 are in contact with the surface of the filter screen 7, one end of the rotating shaft 9 extends into the driving box 8 and is fixed with a plurality of impellers 12, the air inlet pipe 5 is connected with the driving box 8 through a connecting pipe a13, a solenoid valve 14 is installed on the inner wall of the connecting pipe a13, a wind shield 15 is rotatably connected to the inner wall of the dust filter cartridge 3, a first spring 16 is fixed between the upper end of the wind shield 15 and the inner wall of the dust filter cartridge 3, an arc groove 17 is opened on the inner wall of the dust filter cartridge 3, a conductive strip 18 is fixed to the inner wall of the arc groove 17, a conductive block 19 matching the conductive strip 18 is fixed to the side wall of the wind shield 15, and the solenoid valve 14 is electrically connected to the conductive strip 18 through a wire.

[0021] Furthermore, when the filter 7 is not blocked by dust and ventilation is smooth, the wind shield 15 will be blown upwards under the action of the airflow, so that the conductive block 19 is disconnected from the conductive strip 18. After the filter 7 has been used for a long time, a lot of dust and impurities adhere to the surface, causing the ventilation performance of the filter 7 to deteriorate, and then the airflow received by the wind shield 15 will decrease and rotate downward until it rotates to the conductive block 19 and the conductive strip 18 are in contact. At this time, the solenoid valve 14 is energized and opened, and the airflow will enter the drive box 8, blowing the impeller 12 to rotate, and then driving the rotating shaft 9 to rotate, so that the cleaning rod 10 drives the bristles 11 to clean the surface of the filter 7, so that the degree of blockage of the filter 7 can be automatically judged according to the size of the airflow, and cleaning is automatically performed. Compared with the existing manual disassembly and cleaning, it is more convenient and intelligent, and there is no need for manual attention to the degree of blockage of the filter 7 at all times, which greatly reduces the labor intensity of workers.

[0022] The cleaning mechanism also includes a slide 20 fixed on the inner wall of the dust filter cylinder 3, and a slide plug 21 is slidably connected to the inner wall of the slide 20. A push rod 22 is fixedly connected to the upper end of the slide plug 21. The upper end of the push rod 22 is arranged to penetrate the upper end of the slide 20. A second spring 23 is fixedly connected to the top of the slide 20, and the lower end of the second spring 23 is fixedly connected to the slide plug 21. One end of the rotating shaft 9 penetrates the side wall of the slide 20 and extends into the slide 20. The side wall of the rotating shaft 9 located in the slide 20 is fixedly connected to a cam 24, and the cam 24 is against the lower end of the slide plug 21.

[0023] Furthermore, the rotation of the rotating shaft 9 will synchronously drive the cam 24 to rotate, and then under the action of the cam 24 and the second spring 23, the sliding plug 21 will drive the push rod 22 to continuously knock the filter 7, causing the filter 7 to vibrate. Under the action of the vibration, the dust on the filter 7 is easier to be cleaned off, and the cleaning effect is better.

[0024] The inner wall of the driving box 8 is provided with a plurality of dust suction holes 25, the side wall of the dust filter cylinder 3 is fixedly connected with a dust collecting box 26, and the driving box 8 is connected with the dust collecting box 26 via a connecting pipe b27.

[0025] It is worth mentioning that when the filter 7 is cleaned, the airflow will flow rapidly from top to bottom in the drive box 8. According to Bernoulli's theorem, when the airflow is flowing at an equal height, the faster the flow speed, the smaller the pressure generated, and the stronger the suction force generated. Therefore, the dust swept off the filter 7 will be sucked into the drive box 8 through multiple dust suction holes 25, and then the dust will enter the dust collecting box 26 through the connecting pipe b27 together with the airflow to be collected, so as to prevent the swept dust from flying into the air again and polluting the environment.

[0026] A plurality of semiconductor cooling sheets 28 are symmetrically embedded in the inner wall of the dust filter cartridge 3. The plurality of semiconductor cooling sheets 28 are electrically connected to the conductive strip 18 via wires. The cooling surface of the semiconductor cooling sheet 28 is arranged toward the inner side of the dust filter cartridge 3, and the heat release surface of the semiconductor cooling sheet 28 extends through and to the outer side of the dust filter cartridge 3.

[0027] It is worth mentioning that when the filter 7 is severely clogged and cleaned, the amount of air entering the machine room 1 will be reduced, and the heat dissipation effect will decrease. During cleaning, the semiconductor refrigeration plate 28 will be powered on and started to pre-cool the airflow entering the machine room 1, so that the temperature of the airflow entering the machine room 1 decreases. In this way, even if the amount of air entering is reduced, a good cooling and heat dissipation effect can still be guaranteed.

[0028] In the present invention, by starting the air intake fan 4, the outside air will be drawn into the dust filter cylinder 3 through the air inlet 301, and then the air will be pumped into the interior of the machine room 1 through the exhaust pipe 6 and the air inlet pipe 5, so as to dissipate heat for the electrical equipment inside the machine room 1. When the air in the dust filter cylinder 3 flows from bottom to top, the dust contained therein will be intercepted by the filter 7, so as to prevent the dust in the outside air from entering the interior of the machine room 1, causing the electrical equipment inside the machine room 1 to be short-circuited and damaged.

[0029] In addition, when the airflow flows from bottom to top in the dust filter cartridge 3, the wind shield 15 will be blown up, and then the wind shield 15 will rotate upward, so that the conductive block 19 and the conductive strip 18 are in a disconnected state. After long-term use, more and more dust will adhere to the surface of the filter 7, and then the mesh of the filter 7 will be blocked, so that the airflow in the dust filter cartridge 3 is reduced, and then the thrust of the airflow on the wind shield 15 will be reduced. Under the gravity of the wind shield 15 and the pressure of the first spring 16, the wind shield 15 will rotate downward. When the filter 7 is seriously blocked, the wind shield 15 has dropped to the point where the conductive block 19 contacts the conductive strip 18. At this time, the solenoid valve 14 It will be powered on and turned on, and then part of the airflow in the air inlet pipe 5 will enter the drive box 8 through the connecting pipe a13. The airflow will flow rapidly from top to bottom in the drive box 8, blowing multiple impellers 12 to rotate, thereby driving the rotating shaft 9 to rotate, and driving multiple cleaning rods 10 to rotate. The bristles 11 on the cleaning rods 10 will continuously clean the surface of the filter 7 and sweep away the dust adhered to it, so that the entire device can automatically judge the degree of blockage of the filter 7 according to the size of the airflow, and thus automatically clean it. Compared with manual disassembly and cleaning, it is more convenient and quick, and there is no need for manual attention to the degree of blockage of the filter 7 at all times, which greatly reduces the labor intensity of workers.

[0030] During the rotation of the rotating shaft 9, the cam 24 will be driven to rotate. Under the action of the cam 24 and the second spring 23, the sliding plug 21 will slide back and forth up and down on the inner wall of the sliding cylinder 20, driving the push rod 22 to move up and down, constantly hitting the filter 7, causing the filter 7 to vibrate, and the dust on the filter 7 is easier to be cleaned off under the action of the vibration.

[0031] When the filter 7 is being cleaned, the airflow will flow rapidly from top to bottom in the drive box 8. According to Bernoulli's theorem, when the airflow is flowing at an equal height, the faster the flow speed, the smaller the pressure generated, and the stronger the suction force generated. Therefore, the dust swept off the filter 7 will be sucked into the drive box 8 through multiple dust suction holes 25, and then the dust will enter the dust collecting box 26 through the connecting pipe b27 together with the airflow and be collected, so as to prevent the swept dust from flying into the air again and polluting the environment.

[0032] In addition, when the filter 7 is cleaned, part of the airflow from the air inlet pipe 5 will enter the drive box 8, and the air flow entering the machine room 1 will be reduced, thereby worsening the heat dissipation effect in the machine room 1. Therefore, when the filter 7 is cleaned, the conductive block 19 is in contact with the conductive strip 18, and the current loop is connected. At this time, the semiconductor refrigeration plate 28 will be powered on and started to cool the airflow in the dust filter cylinder 3, so that the temperature of the air entering the machine room 1 will be lower, thereby improving the heat dissipation effect and avoiding the deterioration of the heat dissipation effect in the machine room 1 due to the reduction of the air flow entering.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
