Description

Technical Field

[0001] The utility model relates to the technical field of control system cabinets, and specifically relates to a control system for an internal combustion engine generator set. Background Technique

[0002] An internal combustion engine generator set refers to a device that uses an internal combustion engine to drive a generator to supply power. It is used as a backup power source in most communication bureaus (stations). When the mains power is interrupted, the internal combustion engine is started to drive the synchronous AC generator to supply power to ensure that the AC power supply is not interrupted for a long time. In a few special stations, it is used as the main power source. The internal combustion engine can be a gasoline engine or a diesel engine, and the generator set consists of a power system, a control system, a silencing system, a shock absorption system, and an exhaust system. Among them, the control system is the command center of the generator set, responsible for monitoring and adjusting the operating state of the generator set. It is mainly composed of a control cabinet and the electrical components inside it. However, during the use of the control cabinet of the current generator set control system, since ventilation holes are usually opened on its side walls for heat dissipation, and there is no structure for drying the air inside the control cabinet. If the external humid air enters the inside of the control cabinet, it will easily cause the electrical components inside to short-circuit due to moisture. Therefore, we propose a control system for an internal combustion engine generator set to solve the above problems. Content of the Utility Model

Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, a control system for an internal combustion engine generator set proposed by an embodiment of the present utility model includes a control cabinet 1. Both side walls of the control cabinet 1 are fixedly communicated with ventilation pipes 2. Heating wire elements 3 are fixedly arranged inside the ventilation pipes 2. Heat dissipation blocks 4 are fixedly arranged inside the two openings formed on one side of the two ventilation pipes 2. A semiconductor refrigeration sheet 5 is fixedly arranged on one side wall of each heat dissipation block 4. Two groups of inclined plates 6 are arranged inside the ventilation pipes 2. Installation frames 7 are fixedly arranged at the air inlets formed on the side walls of the ventilation pipes 2. Dust-proof nets 8 are inserted inside the installation frames 7. Fixing components 9 for limiting the dust-proof nets 8 are arranged on one side of the two ventilation pipes 2. An exhaust fan 10 is fixedly arranged at the opening formed on the top of the control cabinet 1. A protective net 11 is fixedly arranged on the top of the exhaust fan 10. A support base 12 is fixedly arranged at the bottom of the control cabinet 1. A lifting and moving component 13 is arranged inside the support base 12. This control system for an internal combustion engine generator set consists of a local control cabinet, a unit circuit breaker cabinet, a remote control cabinet, and a central monitoring unit. The system has functions such as gas engine data acquisition, unit control, air-fuel ratio automatic control, unit test system, expert diagnosis system, human-computer interaction, program recovery, event recording, etc. Among them, the local control cabinet mainly consists of a generator main controller, an air-fuel ratio controller, a speed controller, an ignition controller, an intelligent display screen, various data acquisition modules, a voltage control module, a high-power power supply, etc. The generator main controller adopts a high-performance CPU, and its operation speed reaches the nanosecond level, which can quickly respond to signal changes and complete PID control operations. For the PID control tuning, the Lambda tuning method is used, which can ensure that the process variable will not overshoot after interference or set value change;The setting robustness is very good, which can keep the control loop stable even when the process characteristics change greatly. The central monitoring unit is equipped with a GPS positioning module and a wireless communication module. Through the combination of various structures, it can replace the need for manual operation and monitoring of traditional generator sets, not only improving the safety and stability of the equipment, but also reducing the burden on staff. Since the main controller of the generator, the air-fuel ratio controller, the speed control controller, the ignition controller, the intelligent display screen, and various data acquisition modules need to be installed inside the control cabinet during use, and in order to facilitate heat dissipation of the components installed inside the control cabinet during use, ventilation holes will be opened on its side wall to dissipate heat from the components inside. When the external air is relatively humid, due to the single structure of the control cabinet, there is a lack of a structure for drying the air at the ventilation holes. If the external humid air enters the inside of the control cabinet, it will cause the electrical components inside to be short-circuited due to moisture. To solve the problems existing in the control cabinet of this internal combustion engine generator set control system, this case came into being. When it is necessary to dissipate heat inside the control cabinet 1 during the use of this generator set control system, starting the exhaust fan 10 can suck the external air into the inside of the ventilation pipe 2. When the external air enters the inside of the ventilation pipe 2, it can be dried by the heating wire element 3 first, and then the dried air will flow to the semiconductor refrigeration sheet 5 for cooling. Finally, the cooled air will enter the inside of the control cabinet 1 to cool the electrical components. By using the inclined plate 6 arranged inside the ventilation pipe 2, the flow rate of the air inside the ventilation pipe 2 can be delayed, so as to dry and cool it more thoroughly.;

[0027] As Figure 6 shown, there is another way for the fixing component 9 used to limit the dust-proof net 8 in the present utility model. It mainly includes a connecting plate 15 fixed on one side wall of the dust-proof net 8. A U-shaped rod 16 is fixed on one side wall of the connecting plate 15, and a cathode magnet 17 is fixed on one side wall of the connecting plate 15. An anode magnet 18 is fixed on one side wall of the ventilation pipe 2. The anode magnet 18 attracts the cathode magnet 17. During use, with the cooperation of the anode magnet 18 and the cathode magnet 17, the connecting plate 15 and the ventilation pipe 2 are connected and fixed by magnetic attraction. Pulling the U-shaped rod 16 can conveniently separate the dust-proof net 8 from the installation frame 7 for cleaning.

[0028] As Figure 5As shown, in some embodiments, the fixing component 9 includes a fixing plate 901 fixed to one side wall of the dust-proof net 8. A through hole is formed in the side wall of the fixing plate 901, and a bolt 902 is arranged inside the through hole. One end of the bolt 902 is threadedly connected to a threaded hole formed in one side of the ventilation pipe 2. A pulling frame 903 is fixed to one side wall of the fixing plate 901. During use, after releasing the restriction on the fixing plate 901 by rotating the bolt 902, pulling the pulling frame 903 to move can separate the dust-proof net 8 from the installation frame 7, thus facilitating the removal of the dust-proof net 8 for cleaning.

[0029] As Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the lifting and moving component 13 includes a cross plate 1301 fixed between the inner walls on both sides of the support base 12. Two rotating shafts 1302 are rotatably connected to the side wall of the cross plate 1301 through bearings. Transmission wheels 1307 are fixed to the surfaces of the two rotating shafts 1302. The two transmission wheels 1307 are connected by a belt 1308. Under the action of one motor, the two rotating shafts 1302 can be driven to rotate simultaneously, thus saving production costs. Rotating plates 1303 are fixed to one ends of the rotating shafts 1302. T-shaped rods 1304 are movably connected to one side wall of each rotating plate 1303 through T-shaped shafts. Bottom plates 1305 are fixed to the bottoms of the two T-shaped rods 1304. Guide rails 1309 are fixed to the inner walls on both sides of the support base 12. Two L-shaped sliders 1310 adapted to the guide rails 1309 are fixed to the top of the bottom plate 1305, which can play a role in guiding and supporting the bottom plate 1305, so that its up and down movement will be more stable. Rollers 1306 are fixed to the four corners of the bottom of the bottom plate 1305. When the control cabinet 1 needs to be moved, the motor can be started to drive the rotating shaft 1302 to rotate. After the rotating shaft 1302 rotates, it will drive the rotating plate 1303 to rotate. When the rotating plate 1303 drives the T-shaped rod 1304 to rotate by 90 degrees, the bottom plate 1305 can be driven to move down to the maximum extent. After the bottom plate 1305 moves down, it can drive the rollers 1306 to move down. At this time, the control cabinet 1 can be jacked up, and then the control cabinet 1 can be moved closely. After the movement is completed, the motor can be started again to drive the rotating plate 1303 to rotate by 90 degrees. At this time, the rollers 1306 can be retracted, so that the control cabinet 1 can be supported by the support base 12 again.

[0030] As Figure 2 As shown, in some embodiments, two flow guiding plates 14 are fixed inside the ventilation pipes 2, which can further delay the speed of the air flowing to the refrigeration part after being heated and dried, so as to facilitate the semiconductor refrigeration sheet 5 to fully cool the hot and dry air.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
