Description

Technical Field

[0001] This application relates to the field of diesel generators, and more specifically, to a standby diesel generator system. Background Technology

[0002] Backup generator sets are power generation devices that provide emergency power during mains power outages. They are mainly used in hospitals, communication hubs, airports, and other locations with high requirements for power supply reliability. They are diesel-powered and equipped with automatic switching devices, adhering to the principle of dual-power failure start-up. Their power supply range covers particularly important loads in primary loads, fire-fighting loads, and power supply to maintain the minimum operating requirements of facilities. They need to start supplying power within a short time after a municipal power outage.

[0003] Currently, backup diesel generator systems are often integrated structures, with the internal diesel generator system protected by an external protective shell. However, diesel generator systems are commonly used equipment, and they not only need to be repaired promptly when damaged, but also require regular maintenance. However, the method of opening the door panel on the outer shell for maintenance is outdated, and the space available for maintenance personnel is too small, resulting in low maintenance efficiency and limited maintenance content. On the other hand, noise reduction performance is also a key factor affecting the widespread adoption of the entire system. Summary of the Invention

[0004] To overcome the shortcomings of the existing system, this application provides a backup diesel generator system. The diesel generator system is a commonly used device that requires not only timely repair when damaged but also regular maintenance. However, the method of maintenance by opening the door panel on the casing is outdated and the space available for maintenance personnel is too small, resulting in low maintenance efficiency and limited maintenance content. On the other hand, noise reduction performance is also a key factor affecting the widespread adoption of the entire system.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] Diesel generator systems are commonly used equipment that require timely repair when damaged and regular maintenance. However, the current method of opening the door panel on the casing for inspection and maintenance is outdated and the space available for maintenance personnel is too small, resulting in low maintenance efficiency and limited scope of maintenance. Furthermore, noise reduction performance is also a key factor affecting the widespread adoption of the entire system.

[0007] The advantages of this embodiment are: by setting up a crossbar, a vertical bar, a protective main plate, a protective side plate, a servo motor, a hollow sound-absorbing cotton board, and fixing parts, the servo motor drives the crossbar to rotate, and the crossbar drives the vertical bar to rotate, thereby synchronously driving the protective main plate and the protective side plate to flip up, so that almost the entire diesel generator set is exposed. This not only increases the working space for maintenance personnel, but also makes the maintenance more comprehensive. The protective main plate and the protective side plate located at the top will not hinder the maintenance. The hollow sound-absorbing cotton board inside the protective main plate and the protective side plate can greatly reduce external noise. At the same time, the hollow sound-absorbing cotton board can be inspected, cleaned, or replaced while the diesel generator set is being maintained, making the whole system more convenient to use and easy to promote.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0016] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0017] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0018] Please see Figures 1-6 This application provides a standby diesel generator system including a generator assembly 100 and a protection assembly 200.

[0019] Please see Figure 1 , 2 3. The generator assembly 100 includes a base plate 110, a diesel generator set 120 and a support frame 140. The diesel generator set 120 is disposed on the top of the base plate 110 and the support frame 140 is fixedly connected to the base plate 110.

[0020] The supporting frame 140 includes a hollow tube 141 and a top plate 142. The hollow tube 141 is fixedly connected to the bottom plate 110, and the top plate 142 is fixedly connected to the top of the hollow tube 141. By setting the hollow tube 141 and the top plate 142, the hollow tube 141 is used to support the top plate 142 to form a stable frame, providing a stable installation position for the protective plate.

[0021] Please see Figure 1 , 2 4, 5, and 6, the protective component 200 includes a crossbar 210, a longitudinal bar 220, a protective main plate 230, a protective side plate 240, a servo motor 250, a hollow sound-absorbing cotton board 260, and a fastener 280. The crossbar 210 is rotatably mounted within the support frame 140, and the longitudinal bar 220 is rotatably mounted within the support frame 140, with the crossbar 210 and longitudinal bar 220 being perpendicular to each other. The crossbar 210 is driven to the longitudinal bar 220. The protective main plate 230 is fixedly connected to the crossbar 210. The protective side plate 240 is fixedly connected to the longitudinal bar 220. The servo motor 250 is mounted within the support frame 140 and is driven to the crossbar 210. The hollow sound-absorbing cotton board 260 is attached to the protective main plate 230, and the fastener 280 is located inside the protective main plate 230.

[0022] One end of the crossbar 210 is fixedly connected to a first bevel gear 211, and the vertical bar 220 is fixedly connected to a second bevel gear 221. The first bevel gear 211 and the second bevel gear 221 mesh with each other. By setting the first bevel gear 211 and the second bevel gear 221 to mesh, when the servo motor 250 is started to drive the crossbar 210 to rotate, the crossbar 210 drives the first bevel gear 211 to rotate, the first bevel gear 211 meshes and drives the second bevel gear 221 to rotate, and the second bevel gear 221 drives the vertical bar 220 to rotate, thus achieving the purpose of transmission connection.

[0023] Specifically, the fastener 280 includes a groove plate 281 and a fixing bolt 282. The groove plate 281 is fixedly connected to the inner side of the protective main plate 230. One end of the hollow sound-absorbing cotton board 260 is slidably inserted into the groove plate 281. The fixing bolt 282 slides through the hollow sound-absorbing cotton board 260 and is threadedly connected to the protective main plate 230. By setting the groove plate 281 and the fixing bolt 282, when inspecting and maintaining the diesel generator set 120, the fixing bolt 282 can be unscrewed first, and the hollow sound-absorbing cotton board 260 can be pulled out from the groove plate 281. During installation, first slide the hollow sound-absorbing cotton board 260 against the protective main board 230 so that the end of the hollow sound-absorbing cotton board 260 is inserted into the groove plate 281. At this time, the tail end of the hollow sound-absorbing cotton board 260 is in contact with the protective main board 230. Then, re-pass the fixing bolt 282 through the hole at the tail end of the hollow sound-absorbing cotton board 260 and tighten it into the protective main board 230. On the other hand, the protective side plate 240 also has this structure. It can be staggered and not arranged at the position where the window is opened, so as to facilitate cleaning dust or replacing the hollow sound-absorbing cotton board 260. The disassembly and assembly are convenient and quick.

[0024] In this embodiment, the hollow sound-absorbing cotton board 260 includes a hollow board 261 and a sound-absorbing cotton layer 262. The sound-absorbing cotton layer 262 is disposed on the outside of the hollow board 261 and away from the protective main board 230. By setting the hollow board 261 and the sound-absorbing cotton layer 262, the sound-absorbing cotton layer 262 first absorbs some noise, and then the sound insulation cavity of the hollow board 261 isolates some noise, thereby effectively reducing the noise to the outside.

[0025] In one specific implementation, the protective main board 230 has an opening on one side and a door panel 231 is rotatably mounted thereon. The door panel 231 is rotatably connected to the protective main board 230 via a hinge. With the opening and the rotatable door panel 231, a traditional door lock and handle are provided at the contact position of the two door panels 231. Rotating and opening the door panel 231 allows access to the internal diesel generator set 120, which facilitates simple daily inspection, maintenance, or use.

[0026] It should be noted that there is a gap between the protective main plate 230 and the base plate 110, the hollow sound-absorbing cotton board 260 is attached to the side of the hollow sound-absorbing cotton board 260, and there is a gap between the protective main plate 230 and the top surface of the base plate 110. When rotating the protective main plate 230 and the protective side plate 240, the larger gap can avoid interference when rotating the protective main plate 230. The hollow sound-absorbing cotton board 260 is attached to the bottom of the side of the hollow sound-absorbing cotton board 260, thus sealing the interior.

[0027] In one specific implementation, the protective side plate 240 has a ventilation opening 270, and a filter screen 271 is provided inside the ventilation opening 270. By providing the ventilation opening 270 and the filter screen 271, the cooling water tank in the diesel generator set 120 with a large amount of ventilation is ventilated.

[0028] Please see Figure 1 and 6 The protective assembly 200 also includes a shielding assembly 290, which includes a bidirectional lead screw 291, a drive motor 292, and a baffle 293. The bidirectional lead screw 291 is rotatably mounted on the outside of the protective side plate 240. The drive motor 292 is mounted on the outside of the protective side plate 240 and its transmission wheel is connected to the bidirectional lead screw 291. The baffle 293 is threadedly sleeved onto the bidirectional lead screw 291. By setting the bidirectional lead screw 291, the drive motor 292, and the baffle 293, the baffle can be used to shield the protective side plate 240 when it is not in use. The motor 292 drives the bidirectional lead screw 291 to rotate. The bidirectional lead screw 291, through the thread transmission principle, synchronously drives the two baffles 293 to move. The two baffles 293 move closer to each other to block the vent 270, preventing dust from entering the interior through the vent 270 when not in use. When the diesel generator set 120 is turned on, the controller synchronously turns on the drive motor 292 to rotate in the opposite direction, causing the baffles 293 to move away from the vent 270 to both sides, thereby exposing the vent 270 and the filter screen 271 for normal ventilation.

[0029] Among them, a guide rod 241 is provided on the outer side of the protective side plate 240, and the baffle 293 is slidably sleeved on the guide rod 241. By providing the guide rod 241, the movement of the baffle 293 is guided. The baffle 293 moves linearly, limiting the rotation of the baffle 293 by the threaded transmission.

[0030] It should be noted that the servo motor 250 and drive motor 292 are existing motors, and their working principle, size and model are not related to the function of this application, so they will not be described in detail. The control method of this invention is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0031] The working principle of this backup diesel generator system is as follows: When maintenance of the diesel generator set 120 is required, the servo motor 250 is started, driving the crossbar 210 to rotate. The crossbar 210 drives the first bevel gear 211 to rotate, which in turn drives the second bevel gear 221 to rotate. The second bevel gear 221 drives the vertical rod 220 to rotate, which in turn drives the protective main plate 230 to rotate and flip. The vertical rod 220 drives the protective side plate 240 to rotate and flip, thereby vertically flipping each protective main plate 230 and protective side plate 240 to a horizontal state. The flipping angle can be preset, so that almost all of the diesel generator set 120 is exposed. This not only increases the working space for maintenance personnel, but also... The maintenance is more comprehensive. Furthermore, when overhauling the diesel generator set 120, the protective main plate 230 and protective side plate 240 can be opened, and the fixing bolts 282 can be unscrewed to pull the hollow sound-absorbing cotton plate 260 out of the groove plate 281. This makes it convenient to clean the dust or replace the hollow sound-absorbing cotton plate 260, and the disassembly and assembly are convenient and quick. Finally, when the diesel generator set 120 is not in use, the drive motor 292 drives the double-sided lead screw 291 to rotate. The double-sided lead screw 291 drives the two baffles 293 to move synchronously through the thread transmission principle. The two baffles 293 move closer to each other to block the ventilation opening 270, preventing dust from entering the interior through the ventilation opening 270 when not in use. This makes the whole unit more convenient to use and easier to promote.

[0032] It should be noted that the specific models and specifications of the diesel generator set 120, servo motor 250 and drive motor 292 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and operating principles of the diesel generator set 120, servo motor 250 and drive motor 292 are clear to those skilled in the art and will not be described in detail here.

[0034] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
