Description

Technical Field

[0001] The utility model relates to the technical field of safety protection devices for generator sets, and more specifically, to a safety protection device for generator sets. Background Art

[0002] During the operation of diesel generator sets, safety protection devices are crucial, especially in terms of fuel tank pressure control. Diesel generators generate high-temperature and high-pressure gas by burning diesel, which drives the piston to move, thereby driving the crankshaft to rotate, and finally converting mechanical energy into electrical energy through the generator. However, during long-term operation, the temperature and pressure in the fuel tank will gradually increase. If the pressure is too high and cannot be released in time, it may cause serious accidents such as fuel tank rupture, fire or even explosion, posing a great threat to personnel and equipment.

[0003] In order to solve this problem, a pressure relief device is usually used in the existing technology to ensure that the pressure in the fuel tank is maintained within a safe range. The basic principle of this pressure relief device is to automatically open the pressure relief valve to release excess pressure when the pressure in the fuel tank exceeds a preset safety value, thereby protecting the safety of the fuel tank. However, the existing pressure relief device has some limitations. First, due to its relatively simple structure, it is often unable to be flexibly adjusted according to different types of generator sets and different usage conditions. This means that in some specific cases, the pressure relief device may not provide sufficient protection, or may be too sensitive in some cases, resulting in unnecessary pressure release, affecting the normal operation of the generator set.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a generator set safety protection device, which has the following beneficial effects:

[0017] 1. The beneficial effect of the pressure relief device is mainly reflected in its ability to relieve pressure on the fuel tank in a timely and effective manner to prevent accidents caused by excessive pressure in the fuel tank. Through the coordinated work of the pressure relief pipe, connecting rod, sealing plate, fixing plate and tension spring and other components, when the pressure in the fuel tank exceeds the safety value, the sealing plate will be pushed open, allowing the diesel in the fuel tank to flow into the buffer box to achieve pressure relief. This design can not only ensure the safe operation of the generator set, but also extend the service life of the equipment.

By rotating the control sleeve, the gap between the through groove and the baffle block can be changed, thereby limiting the speed at which diesel passes through and achieving the adjustment of the pressure relief flow. At the same time, by pushing the control sleeve and then rotating it, the distance between the fixed plate and the threaded plate can be changed, thereby changing the pressure of the tension spring, and then changing the trigger pressure required for each opening. This design not only improves the applicability of the equipment, but also can meet the needs under different working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

The control sleeve 10 is movably arranged on one side of the pressure relief pipe 4. The threaded sleeve 11 and the threaded plate 14 are movably connected to the inner wall of the pressure relief pipe 4 through threads. The matching rod 12 is fixedly connected between the sealing plate 7 and the connecting rod 5. The adapter block 15 is connected to one end of the connecting rod 5. The adapter sleeve 16 is connected to one end of the push rod 18. The adapter groove 17 is provided on the threaded plate 14. The push rod 18 is connected to the control sleeve 10 through the connecting frame 19.

[0030] A sealing cover 20 is provided above the oil tank 2 , and the sealing cover 20 is detachably installed above the oil tank 2 via threads.

[0031] A transport frame 21 is disposed outside the generator set 1 , and the generator set 1 and the oil tank 2 can be detachably mounted inside the transport frame 21 .

[0032] A placement rack 22 is provided on one side of the transport rack 21 , a buffer bin 23 is provided on one side of the placement rack 22 , and a section of the pressure relief pipe 4 is connected to the buffer bin 23 .

[0033] In this embodiment, when the equipment needs to be used, the provision of the transport frame 21 facilitates the movement of the equipment as a whole, and facilitates the installation and fixation of the fuel tank 2 and the generator set 1 as a whole. The provision of the sealing cover 20 facilitates the addition of diesel into the fuel tank 2. Then, when the equipment is operating normally, the temperature in the fuel tank 2 will gradually increase, which will cause the pressure in the fuel tank 2 to increase. When the pressure value in the fuel tank 2 exceeds the preset safety value, the sealing plate 7 will be pushed open, and the sealing plate 7 will drive the baffle block 24 to move, so that the gap between the baffle block 24 and the through groove 25 becomes larger, and then the sealing tube will drive the connecting rod 5 and the connecting rod 5 together through the matching rod 12. The fixed plate 8 arranged on the side moves, and then the fixed plate 8 will cooperate with the threaded plate 14 to stretch the tension spring 9, and then the diesel in the fuel tank 2 will enter the pressure relief pipe 4 through the connecting pipe 3, and then pass through the gap between the through groove 25 and the baffle block 24, and then flow into the cache box through the gap between the sealing plate 7 and the pressure relief pipe 4, so that the pressure in the fuel tank 2 is released in time to prevent accidents. When the pressure in the fuel tank 2 returns to normal, the tension spring 9 pulls the fixed plate 8 to reset, so that the fixed plate 8 drives the matching rod 12 and the sealing plate 7 to reset through the connecting rod 5, so that the sealing plate 7 closes the pressure relief pipe 4 again.

[0034] See also Figure 2-6 As a further implementation of the adjustment mechanism: a baffle block 24 is provided on one side of the sealing plate 7, a through groove 25 is opened on the threaded sleeve 11, and the position of the through groove 25 corresponds to the position of the baffle block 24.

[0035] The plurality of spoiler blocks 24 have different lengths.

[0036] Bellows 26 are provided on both sides of the control sleeve 10 . The control sleeve 10 and the two bellows 26 are movably connected. The other end of one bellows 26 is fixedly connected to the connecting pipe 3 , and the other end of the other bellows 26 is fixedly connected to the pressure relief pipe 4 .

[0037] An anti-slip strip 27 is disposed on the outer side of the control cover 10 , and the anti-slip strip 27 is fixedly disposed on the outer side of the control cover 10 .

[0038] More specifically, when it is necessary to adjust the trigger mechanism of the pressure relief device according to the usage, the control sleeve 10 can be directly rotated, and the control sleeve 10 will drive the connecting rod 5 to rotate through the cooperation of the adapter sleeve 16 and the adapter block 15, and then the connecting rod 5 will drive the matching rod 12 to rotate. Since the matching rod 12 and the matching groove 13 are both hexagonal structures, the matching rod 12 will drive the threaded sleeve 11 to rotate through the matching groove 13. Since the threaded sleeve 11 is movably connected to the inner wall of the pressure relief pipe 4 through the thread, the threaded sleeve 11 will move spirally along the pressure relief pipe 4, so that the gap between the threaded sleeve 11 and each baffle block 24 changes, thereby changing the gap between the through groove 25 and each baffle block 24, thereby limiting the space for diesel to pass through, so as to change the speed of diesel passing through each time it is turned on, and then the control sleeve 10 can be pushed to one side, so that the control sleeve 10 drives the push rod 18 to push the adapter block 15 to move through the connecting frame 19. The adapter block 15 is inserted into the adapter groove 17 opened on the inner side of the threaded plate 14, and then the control sleeve 10 is rotated. The control sleeve 10 drives the adapter block 15 to rotate through the push rod 18 and the adapter sleeve 16, and then the adapter block 15 will drive the threaded plate 14 to rotate through the adapter groove 17. Since the adapter groove 17, the inner sides of the adapter block 15 and the adapter sleeve 16 are all hexagonal structures, and the threaded plate 14 is movably installed in the pressure relief pipe 4 through threads, then the threaded plate 14 will spirally slide in the pressure relief pipe 4, so that the distance between the fixed plate 8 and the spiral plate changes, and then the gap between the tension springs 9 will change, so that the pressure required to trigger each existing opening will change. When the adjustment is appropriate, the control sleeve 10 can be pulled to the opposite side for reset. When the opening pressure needs to be adjusted separately, the threaded sleeve 11 can be moved back to its original position by referring to the above process. At the same time, the setting of the device can also be manually pushed The control sleeve 10 is manually released.

[0039] In summary, when the overall equipment is in use or running: when the equipment needs to be used, the setting of the transport frame 21 facilitates the movement of the overall equipment, and at the same time facilitates the installation and fixation of the fuel tank 2 and the generator set 1 as a whole. The setting of the sealing cover 20 facilitates the addition of diesel into the fuel tank 2. Then, when the equipment is operating normally, the temperature in the fuel tank 2 will gradually increase, which will cause the pressure in the fuel tank 2 to increase. When the pressure value in the fuel tank 2 exceeds the preset safety value, the sealing plate 7 will be pushed open, and at the same time, the sealing plate 7 will drive the baffle block 24 to move, so that the gap between the baffle block 24 and the through groove 25 becomes larger, and then the sealing tube will drive the connecting rod 5 and through the matching rod 12. The fixed plate 8 set on one side of the connecting rod 5 moves, and then the fixed plate 8 will cooperate with the threaded plate 14 to stretch the tension spring 9, and then the diesel in the fuel tank 2 will enter the pressure relief pipe 4 through the connecting pipe 3, and then pass through the gap between the through groove 25 and the baffle block 24, and then flow into the cache box through the gap between the sealing plate 7 and the pressure relief pipe 4, so that the pressure in the fuel tank 2 is released in time to prevent accidents. When the pressure in the fuel tank 2 returns to normal, the tension spring 9 pulls the fixed plate 8 to reset, so that the fixed plate 8 drives the matching rod 12 and the sealing plate 7 to reset through the connecting rod 5, so that the sealing plate 7 closes the pressure relief pipe 4 again.

[0040] When it is necessary to adjust the trigger mechanism of the pressure relief device according to the usage, the control sleeve 10 can be directly rotated. The control sleeve 10 will drive the connecting rod 5 to rotate through the cooperation of the adapter sleeve 16 and the adapter block 15, and then the connecting rod 5 will drive the matching rod 12 to rotate. Since the matching rod 12 and the matching groove 13 are both hexagonal structures, the matching rod 12 will drive the threaded sleeve 11 to rotate through the matching groove 13. Since the threaded sleeve 11 is movably connected to the inner wall of the pressure relief pipe 4 through the thread, the threaded sleeve 11 will move spirally along the pressure relief pipe 4, so that the gap between the threaded sleeve 11 and each baffle block 24 changes, thereby changing the gap between the through groove 25 and each baffle block 24, thereby limiting the space for diesel to pass through, so as to change the speed of diesel passing through each time it is turned on, and then the control sleeve 10 can be pushed to one side, so that the control sleeve 10 drives the push rod 18 to push the adapter block 15 to move through the connecting frame 19, so that the adapter The adapter block 15 is inserted into the adapter groove 17 opened on the inner side of the threaded plate 14, and then the control sleeve 10 is rotated. The control sleeve 10 drives the adapter block 15 to rotate through the push rod 18 and the adapter sleeve 16, and then the adapter block 15 will drive the threaded plate 14 to rotate through the adapter groove 17. Since the adapter groove 17, the inner sides of the adapter block 15 and the adapter sleeve 16 are all hexagonal structures, and the threaded plate 14 is movably installed in the pressure relief pipe 4 through threads, then the threaded plate 14 will spirally slide in the pressure relief pipe 4, so that the distance between the fixed plate 8 and the spiral plate will change, and then the gap between the tension springs 9 will change, so that the pressure required to trigger each existing opening will change. When the adjustment is appropriate, the control sleeve 10 can be pulled to the opposite side for reset. When the opening pressure needs to be adjusted separately, the threaded sleeve 11 can be moved back to its original position by referring to the above process. At the same time, the setting of the device can also be manually pushed The control sleeve 10 is manually released.
