Description

Technical Field

[0001] The present invention relates to the technical field of diesel generator set installation, and particularly to a diesel generator set installation cabinet. Background Art

[0002] As a commonly used power supply device, diesel generator sets are widely rented for use in harsh environments. The external protection of diesel generators in harsh environments is particularly important. Therefore, current diesel generator sets usually adopt container-type units to protect the diesel generators installed therein.

[0003] However, the structure of the current diesel generator installation cabinet is relatively simple, with poor utilization of the waste heat and power of the generator exhaust. When the generator exhaust is blocked, it cannot be detected and adjusted in time, resulting in potential safety hazards during use, requiring frequent manual inspections, and unable to adjust the noise reduction effect according to the generator operating conditions, resulting in relatively large noise pollution.

A plurality of leakage holes are opened on the top of the mounting seat.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. In the present invention, for a diesel generator set installation cabinet, the diesel generator is fixedly installed on the top of the mounting seat, and the exhaust port of the generator is located directly below the connecting pipe. Then, the handle is pulled upward to drive the clamping plate out of the clamping groove. Then, while maintaining the upward pulling force on the handle and controlling its rotation, the rotating plate and the adjusting screw rod are driven to rotate synchronously. The adjusting screw rod drives the connecting pipe to move downward through the threaded cooperation with the adjusting hoop plate, so that the connecting pipe is butted against the exhaust port of the generator. A flange is arranged at the bottom of the outer side of the connecting pipe, and the connection with the generator is realized through the flange. Then, the handle is released, so that the handle moves downward under the action of the compression spring and drives the clamping plate to be clamped into the clamping groove to lock the rotating plate. By starting the fan to ventilate the inside of the cabinet body, the heat dissipation efficiency of the diesel generator is improved;

[0023] 2. In the present invention, for the installation cabinet of a diesel generator set, the exhaust gas generated during the operation of the diesel generator is introduced into the connecting pipe, and then discharged successively through the exhaust pipe, the second air guide frame, the thin pipe, the first air guide pipe, the connecting pipe, the intake pipe, the communicating pipe, the outlet pipe, the fixed cylinder and the rotating cylinder. When the gas passes through the exhaust cylinder, it can generate a thrust on the rotating blades, thereby driving the rotating cylinder to rotate. The rotating cylinder drives the driving bevel gear to rotate synchronously. The driving bevel gear drives the transmission shaft and the impeller to rotate through meshing with the driven bevel gear, so as to suck the external cold water through the water inlet pipe and then introduce it into the water outlet pipe. The water flowing through the water outlet pipe is preheated under the high temperature inside the cabinet body and then enters the water tank. At the same time, it can cool the air inside the cabinet body, further improving the heat dissipation effect of the diesel generator. Moreover, the water outlet pipe can be directly in contact with the radiator fins of the generator, further improving the heat dissipation effect. The high-temperature exhaust gas flowing through the thin pipe can further heat the water in the water tank, so as to absorb the waste heat. The water with increased temperature flows upward and is discharged from the drain pipe for introduction into the boiler to realize the utilization of hot water;

[0024] 3. In the present invention, for the installation cabinet of a diesel generator set, when the exhaust gas flows through the intake pipe, the noise vibration sound waves inside it can be transmitted through the fine holes to the gap between the first partition board and the second partition board and act on the outer sides of the communicating pipe and the outlet pipe. At the same time, when the gas flows through the communicating pipe and the outlet pipe, the sound waves generated by its vibration act on the inner sides of the communicating pipe and the outlet pipe, so that they can cancel each other out, achieving a sound insulation effect;

[0025] 4. In the present invention, for the described diesel generator set installation cabinet, ultrasonic waves are emitted by an ultrasonic transmitter, and received by an ultrasonic receiver. Then, the controller determines the ultrasonic wave propagation speed based on the time difference between ultrasonic wave reception and transmission. Since the propagation speed of ultrasonic waves is related to the wind speed, the wind speed inside the fixed cylinder can be calculated. When it is detected that the wind speed increases, the controller controls the output end of the electric push rod to extend, thereby driving the second soundproof cylinder to move to the right, thus expanding the distance between the first partition plate and the second partition plate, thereby enhancing the soundproof effect. At the same time, the second soundproof cylinder drives the abutting wheel to move horizontally through the connecting rod. The abutting wheel drives the sliding ring to move to the right by abutting against the sliding ring. The sliding ring drives the connecting rod and the rack to move to the right. The rack drives the rotating blade to rotate around the rotating shaft through meshing with the transmission gear, thereby reducing the inclination angle between the rotating blade and the right side of the rotating cylinder, thus making the gap between each blade smaller, thereby increasing the exhaust air resistance, and at the same time increasing the rotation speed of the rotating cylinder, and further increasing the rotation speed of the impeller, so that the water pumping speed of the pump housing increases, thereby enhancing the waste heat recovery effect of the exhaust gas. Conversely, when it is detected that the wind speed inside the fixed cylinder decreases, the controller controls the output end of the electric push rod to shorten, thereby driving the second soundproof cylinder to move to the left, thus making the gap between each blade larger, thereby reducing the exhaust air resistance and facilitating smooth exhaust. When it is detected that the wind speed inside the fixed cylinder is less than the preset value, the controller controls the alarm to start, enhancing the risk of blockage inspection of the diesel generator by the staff;

[0026] 5. In the present invention, for the described diesel generator set installation cabinet, the waste heat and power of the exhaust gas discharged by the diesel generator can be recovered and utilized through the provided power recovery mechanism, water pumping mechanism and waste heat recovery mechanism. The ultrasonic wind speed measuring device can measure the exhaust gas flow rate, send out alarm information in time when blocked, and adjust the exhaust back pressure according to the flow rate to maintain stable exhaust. And in cooperation with the adjustable soundproof mechanism, the soundproof intensity can be automatically adjusted according to the exhaust gas volume, reducing noise pollution.

[0053] A water inlet pipe 602 and a water outlet pipe 603 are respectively communicated inside the water inlet and the water outlet of the pump housing 601. The water outlet pipe 603 is arranged in a bent shape. The other end of the water outlet pipe 603 is communicated with the water tank 201.

[0054] In this embodiment, ventilation holes are provided on both sides of the cabinet body 1. A fan 104 is arranged inside the ventilation holes. A ventilation grille 103 is arranged on the front side of the cabinet body 1. A buffer pad 801 is fixedly connected to the top of the bottom plate 102. An installation seat 8 is fixedly installed on the top of the buffer pad 801. A plurality of leakage holes are provided on the top of the installation seat 8.

[0055] In this embodiment, during use, the diesel generator is fixedly installed on the top of the installation seat 8, and the exhaust port of the generator is located directly below the connecting pipe 301. Then, the handle 310 is pulled upward to drive the clamping plate 308 out of the clamping groove. Then, the upward pulling force on the handle 310 is maintained and its rotation is controlled, thereby driving the rotating plate 306 and the adjusting screw 305 to rotate synchronously. The adjusting screw 305 drives the connecting pipe 301 to move downward through the threaded cooperation with the adjusting hoop plate 302, so that the connecting pipe 301 is butted against the exhaust port of the generator. A flange is arranged at the bottom of the outer side of the connecting pipe 301, and the connection with the generator is realized through the flange. Then, the handle 310 is released, so that the handle 310 moves downward under the action of the compression spring 309 and drives the clamping plate 308 to be clamped into the clamping groove to lock the rotating plate 306. By starting the fan 104, ventilation is carried out inside the cabinet body 1 to improve the heat dissipation efficiency of the diesel generator;

[0056] During the operation of the diesel generator, the exhaust gas generated is introduced into the connecting pipe 301, and then passes through the exhaust pipe 207, the second air guide frame 206, the thin pipe 205, the first air duct, the connecting pipe 204, the intake pipe 405, the communicating pipe 407, the outlet pipe 406, the fixed cylinder 501 and the rotating cylinder 503 in sequence and is discharged. When the gas passes through the exhaust cylinder, it can generate a thrust on the rotating blades, thereby driving the rotating cylinder 503 to rotate. The rotating cylinder 503 drives the driving bevel gear 504 to rotate synchronously. The driving bevel gear 504 drives the transmission shaft 605 and the impeller 604 to rotate through meshing with the driven bevel gear 606, so as to suck the external cold water through the water inlet pipe 602 and then introduce it into the water outlet pipe 603. The water flowing through the water outlet pipe 603 is preheated under the high temperature inside the cabinet 1 and then enters the water tank 201. At the same time, it can cool the air inside the cabinet 1, further improving the heat dissipation effect of the diesel generator. And the water outlet pipe 603 can be in direct contact with the radiator of the generator to further improve the heat dissipation effect. The high-temperature exhaust gas flowing through the thin pipe 205 can further heat the water in the water tank 201, so as to absorb the waste heat. The water with an increased temperature flows upward and is discharged from the drain pipe 202 for introduction into the boiler to realize the utilization of hot water;

[0057] When the exhaust gas flows through the intake pipe 405, the internal noise vibration sound waves can be transmitted through the fine holes to the gap between the first partition plate 403 and the second partition plate 404 and act on the outer sides of the communicating pipe 407 and the outlet pipe 406. At the same time, when the gas flows through the communicating pipe 407 and the outlet pipe 406, the sound waves generated by its vibration act on the inner sides of the communicating pipe 407 and the outlet pipe 406, so that they can cancel each other out, achieving a sound insulation effect;

[0058] The ultrasonic wave is emitted by the ultrasonic transmitter 901, and the ultrasonic receiver 902 receives the ultrasonic wave. Thus, the controller 7 judges the ultrasonic wave propagation speed according to the time difference between the ultrasonic wave reception and emission. Since the ultrasonic wave propagation speed is related to the wind speed, the wind speed in the fixed cylinder 501 can be calculated. When it is monitored that the wind speed increases, the controller 7 controls the output end of the electric push rod 412 to extend, thereby driving the second sound insulation cylinder 402 to move to the right, thus expanding the distance between the first partition plate 403 and the second partition plate 404, thereby improving the sound insulation effect. At the same time, the second sound insulation cylinder 402 drives the abutting wheel 511 to move horizontally through the connecting rod 512. The abutting wheel 511 drives the sliding ring 510 to move to the right through the abutting with the sliding ring 510. The sliding ring 510 drives the connecting rod 509 and the rack 508 to move to the right. The rack 508 drives the rotating blade 505 to rotate around the rotating shaft 506 through the meshing with the transmission gear 507, thereby reducing the inclination angle between the rotating blade and the right side of the rotating cylinder 503, so that the gap between each blade becomes smaller, thereby increasing the exhaust air resistance. At the same time, the rotation speed of the rotating cylinder 503 is increased, and then the rotation speed of the impeller 604 is increased, so that the water pumping speed of the pump housing 601 is increased, thereby improving the waste heat recovery effect of the exhaust gas. On the contrary, when it is monitored that the wind speed in the fixed cylinder 501 decreases, the controller 7 controls the output end of the electric push rod 412 to shorten, thereby driving the second sound insulation cylinder 402 to move to the left, so that the gap between each blade becomes larger, thereby reducing the exhaust air resistance and facilitating smooth exhaust. When it is monitored that the wind speed in the fixed cylinder 501 is less than the preset value, the controller 7 controls the alarm 701 to start, enhancing the risk of blockage of the diesel generator set for the staff to check.

[0059] The above has introduced in detail a diesel generator set installation cabinet provided by the present invention. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
