Abstract
Description
Technical Field
[0001] This invention relates to the field of diesel generator set technology, specifically to a seismic-resistant fire-fighting diesel generator set. Background Technology
[0002] Diesel piston internal combustion engines are widely used in fire emergency power supply scenarios due to their stable operation and strong adaptability. Currently, most of these machines are directly fixed to rigid bases, lacking a proper shock absorption structure. The vibration generated by the internal combustion engine itself, combined with external impacts from earthquakes and equipment transportation, can easily cause loosening and leakage in engine connecting parts, fuel lines, and fuel tanks, shortening the service life of the equipment and threatening the safety of emergency operations.
[0003] The fuel supply system directly affects the combustion conditions and operating status of internal combustion engines. Diesel fuel is prone to mixing with water and impurities during storage and use. Traditional equipment relies solely on natural sedimentation and simple filters for oil-water separation, which has limited effectiveness. It also requires regular manual maintenance, has a low degree of automation, and cannot meet the requirements of fire emergency equipment for immediate availability and minimal maintenance.
[0004] Furthermore, the venting structure of the internal combustion engine fuel tank has design flaws. When the equipment is operating, the continuous pumping of fuel creates negative pressure inside the tank, requiring the introduction of air to balance the pressure. However, the normally open venting structure introduces humid air, accelerating diesel fuel deterioration, and the "breathing effect" caused by diurnal temperature variations further exacerbates this problem. The existing structure cannot simultaneously achieve pressure balance and moisture-proof sealing.
[0005] Therefore, existing fire-fighting diesel internal combustion engines have significant shortcomings in terms of earthquake resistance, fuel purification, and fuel tank pressure regulation, making it difficult to cope with complex disaster conditions such as earthquakes. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides an earthquake-resistant fire-fighting diesel generator set, which solves the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a seismic-resistant fire-fighting diesel generator set, comprising a diesel engine body mounted on top of a generator body, the diesel engine body being internally connected to the generator body, a water tank radiator disposed on one side of the generator body and communicating with the interior of the diesel engine body, an air filter mounted on one top end of the diesel engine body, a base mechanism mounted on the bottom of the generator body for buffering against the generator body, casters mounted on the bottom of the base mechanism, and an oil tank mounted inside the base mechanism, the oil tank communicating with one bottom end of an oil supply pipe, one top end of the oil supply pipe communicating with an oil pump inside the diesel engine body, one end of the oil tank communicating with a filter mechanism, and the other end of the oil tank communicating with a pressure balancing assembly.
[0008] Preferably, the base mechanism includes a top plate, which is fixedly connected to the bottom of the generator body by bolts. The top plate is fixedly connected to one end of a damping telescopic rod, the middle of the damping telescopic rod is connected to a lifting plate, and a first spring is fitted on the outside of the damping telescopic rod. Four damping telescopic rods are provided, and one bottom end of each of the four damping telescopic rods is fixedly connected to the base plate. This base mechanism achieves a reliable connection by fixing the top plate to the bottom of the generator body with bolts. The combination structure of the damping telescopic rod and the first spring provides multi-level buffering and energy absorption for vibrations generated during unit operation and earthquake transportation. The four damping telescopic rods are symmetrically arranged on the base plate to form a stable support frame, allowing the lifting plate to maintain directional movement during vibration reduction. The remaining vibration force is transmitted to the filtration mechanism to drive the oil-water mixture to circulate and separate, thereby ensuring the seismic stability of the unit while realizing the recovery and reuse of vibration energy.
[0009] Preferably, the bottom of the oil tank is inclined, and the oil tank is equipped with baffles that are distributed in a straight line at equal intervals. The surface of the baffles is evenly distributed with grooves. The inclined bottom of the oil tank allows the oil-water mixture to naturally converge towards the lower end under gravity. The baffles, which are distributed in a straight line at equal intervals, form a multi-stage slow-flow channel. The grooves evenly distributed on the surface of the baffles disperse and homogenize the flowing oil-water mixture, reduce the impact of oil sloshing, and promote the rising of bubbles and the settling of impurities. This improves the separation efficiency of the subsequent filtration mechanism and ensures the stability of the oil supply.
[0010] Preferably, the filtration mechanism includes a circulation component and a drainage component. The circulation component is installed on the base plate surface and communicates with the inside of the oil tank. The circulation component is used to extract oil from the inside of the oil tank. The drainage component is communicated with the circulation component and is used to discharge water from the inside of the oil tank. The drainage component is installed on the base plate surface. This filtration mechanism forms a modular structure by integrating the circulation component and the drainage component on the base plate surface. It utilizes the communication between the circulation component and the inside of the oil tank to achieve active suction and circulation of the oil-water mixture. The drainage component, in conjunction with the circulation separation, directs the discharge of the water after circulation separation. This allows the oil-water separation and purification process to operate continuously and automatically without external power, directly utilizing the vibration force of the base mechanism. This simplifies the system structure and improves the reliability of the equipment in fire emergency situations.
[0011] Preferably, the circulation assembly includes a slide rod, one top end of which is connected to the bottom of the lifting plate, and one bottom end of which is fitted with a first piston located inside a pressure chamber. The bottom of the pressure chamber is fixedly connected to a base plate. A first connecting groove and a second connecting groove are connected to one side of the bottom of the pressure chamber. A second spring is disposed inside the first connecting groove. A first block is disposed at the end of the first connecting groove away from the pressure chamber. One end of the first connecting groove is connected to a first connecting pipe. One top end of the first connecting pipe is connected to an oil tank via a connector. A second block is disposed at the end of the second connecting groove near the pressure chamber. A third spring is disposed on one side of the second block. One end of the second connecting groove is connected to one end of the connecting pipe. The surfaces of the first and second block are provided with... The first and second plugs are equipped with through holes, which are distributed on their edges. One end of the first connecting pipe has a corrugated structure. The circulation assembly transmits the up-and-down movement of the lifting plate to the first piston through a slide rod, so that the first piston forms a reciprocating pumping action in the pressure chamber. When the first piston moves upward, the second plug closes the second connecting groove, and the negative pressure in the first connecting groove opens the first plug to extract the oil-water mixture in the oil tank. When the first piston moves downward, the first plug closes the first connecting groove, and the positive pressure in the pressure chamber opens the second plug to force the mixture into the drainage assembly, realizing unidirectional continuous conveying. The corrugated structure at the top of the first connecting pipe adapts to the shock-absorbing displacement of the lifting plate, thereby converting the unit's vibration force into the driving force for oil-water separation, realizing automatic circulation filtration without external power.
[0012] Preferably, the drainage assembly includes a sedimentation cylinder, which is fixedly connected to a base plate. One side of the bottom of the sedimentation cylinder is connected to a second connecting pipe, and the outer wall of the middle section of the sedimentation cylinder is connected to a third connecting pipe. One top end of the third connecting pipe is connected to an oil tank and has a corrugated structure. A lifting block is installed inside the sedimentation cylinder. The lifting block has a hollow structure, and its outer wall is in close contact with the inner wall of the sedimentation cylinder. One bottom end of the lifting block is connected to the top end of a connecting rod, and the outer wall of the connecting rod is slidably connected to one bottom end of the sedimentation cylinder. A pull block is fixedly connected to one bottom end of the sedimentation cylinder, and a fourth spring is installed at the bottom of the lifting block. A filter screen is installed below the four springs and is fixedly installed on the inner wall of the sedimentation cylinder. The drainage assembly forms a stable separation chamber by fixing the sedimentation cylinder and the bottom plate. The second connecting pipe receives the oil-water mixture transported by the circulation assembly and causes the water to settle at the bottom of the sedimentation cylinder. The upper oil is filtered through the filter screen and then flows back to the oil tank through the third connecting pipe. The corrugated structure at the top of the third connecting pipe adapts to the shock-absorbing displacement of the bottom plate. By operating the pull block, the lifting block is driven to move down through the connecting rod to close the channel of the third connecting pipe and compress the water in the sedimentation cylinder. The water backwashes the filter screen and then opens the bottom drainage structure to discharge, realizing the automatic cleaning of the filter screen and the discharge of sewage. Thus, while ensuring continuous oil-water separation, the filtration device can be self-maintained.
[0013] Preferably, the bottom side of the sedimentation cylinder is connected to the drainage chamber. A third block is provided inside the drainage chamber, and a fifth spring is inserted inside the third block. An adjusting block is provided at one end of the fifth spring. The adjusting block is fixedly connected to one end of an adjusting bolt, and the adjusting bolt is threadedly connected to one end of the drainage chamber. The bottom of the drainage chamber is connected to the drain outlet. The drainage chamber forms a one-way controllable drainage valve through the cooperation of the third block and the fifth spring. The water pressure generated by the downward pressure of the lifting block opens the third block, allowing water and impurities in the sedimentation cylinder to enter the drainage chamber and be discharged through the drain outlet. The adjusting bolt drives the adjusting block to compress or release the fifth spring to adjust the opening pressure threshold of the third block, thereby adapting to the drainage needs under different oil viscosities and impurity contents, and realizing precise control of the backwashing force of the filter screen and directional discharge of sewage.
[0014] Preferably, one end of the oil tank is fixedly connected to the slide groove, the interior of the slide groove is in communication with the interior of the oil tank, the slide groove slides and fits tightly against the interior of the sleeve, the outer wall of the slide groove is provided with a slot, the slot of the outer wall of the slide groove is aligned with the slot of the outer wall of the sleeve through a sliding fit, a filter tube is provided on the outer wall of the sleeve, the surface of the filter tube is provided with filter holes aligned with the slot of the sleeve surface, the bottom of the slide groove is in communication with the slide tube, one bottom end of the slide tube slides in contact with the inner wall of the compensation tube, one bottom end of the compensation tube is fixedly connected to the base plate, a piston block is provided inside the compensation tube, a sixth spring is provided at the top and bottom of the piston block, and one top end of the compensation tube is aligned with the bottom of the sleeve. Fixed connection; the pressure balancing component is connected to the inside of the oil tank through a sliding groove and slides against the casing to form a variable ventilation channel. The vibration of the unit's operation drives the sliding groove to slide up and down relative to the casing, so that the groove orifice and the casing orifice are aligned to allow external air to flow through and prevent negative pressure in the oil tank. When the unit stops working, the sliding groove is stationary, and the orifice and the casing are misaligned and sealed to prevent humid air from entering. It works with the filter tube on the outer wall of the casing to filter and remove impurities from the incoming air. Through the sliding contact between the sliding tube and the compensation tube, and the adaptive sliding adjustment of the piston block in the compensation tube under the action of the sixth spring, the pressure change caused by the breathing effect of the oil tank due to the day and night temperature difference is balanced, so as to achieve intelligent switching between moisture prevention and pressure stability while ensuring smooth oil supply.
[0015] This invention provides a seismically resistant diesel generator set for fire fighting. It has the following advantages: This earthquake-resistant fire-fighting diesel generator unit absorbs most of the vibration force generated during operation through the damping telescopic rod and the first spring in the base mechanism. Simultaneously, the remaining vibration force drives the lifting plate, which in turn moves the first piston up and down within the pressure chamber, creating a unidirectional suction effect that continuously transports the oil-water mixture from the tank to the settling tank for oil-water separation. The settled water remains at the bottom of the settling tank, while the filtered oil automatically flows back to the tank, achieving automatic oil-water separation and purification without external power. The water level is monitored through a transparent observation window on the outer wall of the settling tank. When the water level is high, an operating block drives the lifting block to move downwards, sealing the oil return path. The flow channel compresses the water in the sedimentation tank, causing the water to backwash the filter screen and push open the third block to discharge through the drain chamber and drain outlet, completing the automatic cleaning of the filter screen and wastewater discharge. At the same time, the working vibration drives the slide groove to slide up and down relative to the sleeve, so that the slide groove and the sleeve groove are aligned during operation to connect with the external air and prevent negative pressure in the oil tank. When the operation stops, they are misaligned and sealed to prevent humid air from entering. The piston block in the compensation pipe adaptively slides and adjusts to balance the breathing effect caused by the temperature difference between day and night. Thus, while ensuring the shock absorption effect, the oil-water separation, filtration and cleaning and pressure balance are achieved in a fully automatic coordinated operation.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1: Please refer to Figure 1-9 This invention provides a technical solution: a seismic-resistant fire-fighting diesel generator set, comprising a diesel engine body 1, which is mounted on top of a generator body 2. The diesel engine body 1 is internally connected to the generator body 2. A water tank radiator 3 is provided on one side of the generator body 2 and is connected to the interior of the diesel engine body 1. An air filter 4 is installed at one top end of the diesel engine body 1. A base mechanism 5 is installed at the bottom of the generator body 2. The base mechanism 5 is used for buffering with the generator body 2. A caster wheel 7 is installed at the bottom of the base mechanism 5, and an oil tank 6 is installed inside the base mechanism 5. The oil tank 6 is connected to one bottom end of an oil supply pipe 10, and one top end of the oil supply pipe 10 is connected to an oil pump inside the diesel engine body 1. One end of the oil tank 6 is connected to a filter mechanism 8, and the other end of the oil tank 6 is connected to a pressure balance component 9. This earthquake-resistant fire-fighting diesel generator set integrates the diesel engine body 1 and generator body 2 onto the base mechanism 5. The combination of the base mechanism 5 and casters 7 allows the unit to move quickly while effectively buffering vibrations generated during earthquakes or transportation, preventing internal components from loosening or being damaged. By integrating an oil tank 6 inside the base mechanism 5 and connecting it to a filter mechanism 8 and a pressure balancing component 9, the unit can automatically circulate and purify the oil-water mixture using its own vibrations during operation. This continuously removes water and impurities from the diesel fuel without manual intervention. Simultaneously, it automatically balances the pressure inside and outside the oil tank 6 during oil extraction to prevent negative pressure. In non-operating conditions, it automatically cuts off external airflow to prevent humid air from entering and can adaptively adjust to the breathing effect caused by day-night temperature differences. This significantly reduces maintenance costs while ensuring diesel quality, guaranteeing the equipment's availability and operational reliability in fire emergency situations.
[0020] Example 2: Please refer to Figure 1-9This invention provides a technical solution: the base mechanism 5 includes a top plate 501, which is fixedly connected to the bottom of the generator body 2 by bolts. The top plate 501 is fixedly connected to one end of the damping telescopic rod 503. The middle part of the damping telescopic rod 503 is connected to the lifting plate 502. A first spring 504 is fitted on the outside of the damping telescopic rod 503. Four damping telescopic rods 503 are provided, and one end of the bottom of the four damping telescopic rods 503 is fixedly connected to the base plate 505. The bottom of the oil tank 6 is inclined. A partition is provided inside the oil tank 6. The partitions inside the oil tank 6 are distributed in a straight line at equal intervals. The surface of the partitions inside the oil tank 6 is evenly distributed with grooves. The filtration mechanism 8 includes a circulation component and a drainage component. The circulation component is installed on the surface of the base plate 505. The ring assembly is connected to the inside of the oil tank 6. The circulation assembly is used to extract oil from the inside of the oil tank 6. The drainage assembly is connected to the circulation assembly. The drainage assembly is used to drain water from the inside of the oil tank 6. The drainage assembly is installed on the surface of the base plate 505. The circulation assembly includes a slide rod 801. One top end of the slide rod 801 is connected to the bottom of the lifting plate 502. A first piston 802 is fitted onto one bottom end of the slide rod 801. The first piston 802 is located inside the pressure chamber 803. The bottom of the pressure chamber 803 is fixedly connected to the base plate 505. A first connecting groove 806 and a second connecting groove 809 are connected to one side of the bottom of the pressure chamber 803. A second spring 808 is installed inside the first connecting groove 806. A first block 807 is installed at the end of the first connecting groove 806 away from the pressure chamber 803. One end of the connecting groove 806 is connected to the first connecting pipe 805. The top end of the first connecting pipe 805 is connected to the oil tank 6 through the connector 804. A second block 811 is provided inside the second connecting groove 809 near the pressure chamber 803. A third spring 810 is provided on one side of the second block 811. One end of the second connecting groove 809 is connected to one end of the connecting pipe. Through holes are provided on the surfaces of the first block 807 and the second block 811. The through holes on the surfaces of the first block 807 and the second block 811 are distributed on the edges of the first block 807 and the second block 811. The top end of the first connecting pipe 805 has a corrugated structure. The drainage component includes a sedimentation cylinder 813, which is fixedly connected to the bottom plate 505. One side of the bottom of the sedimentation cylinder 813 is connected to the second connecting pipe 812. The sedimentation cylinder 813 is connected to the outer wall of the middle section and to the third connecting pipe 819. The top end of the third connecting pipe 819 is connected to the oil tank 6. The top end of the third connecting pipe 819 has a corrugated structure. A lifting block 814 is provided inside the sedimentation cylinder 813. The lifting block 814 has a hollow structure. The outer wall of the lifting block 814 is in close contact with the inner wall of the sedimentation cylinder 813 and slides in contact. The bottom end of the lifting block 814 is connected to the top end of the connecting rod 816. The outer wall of the connecting rod 816 is slidably connected to the bottom end of the sedimentation cylinder 813. A pull block 818 is fixedly connected to the bottom end of the sedimentation cylinder 813. A fourth spring 815 is provided at the bottom of the lifting block 814. A filter screen 817 is provided below the fourth spring 815 and is fixedly installed on the inner wall of the sedimentation cylinder 813.The bottom side of the sedimentation cylinder 813 is connected to the drainage chamber 820. A third block 821 is provided inside the drainage chamber 820. A fifth spring 822 is inserted inside the third block 821. An adjusting block 823 is provided at one end of the fifth spring 822. The adjusting block 823 is fixedly connected to one end of the adjusting bolt 824. The adjusting bolt 824 is threadedly connected to one end of the drainage chamber 820. The bottom of the drainage chamber 820 is connected to the drain outlet 825. In this embodiment, when the diesel engine unit is in use, the vibration generated during operation will cause the lifting plate 502 to move up and down. The lifting plate 502, through the damping telescopic rod 503 and the first spring 504, will absorb the vibration. The damping telescopic rod 503 and the first spring 504 will absorb a large amount of vibration force. The remaining vibration force will cause the lifting plate 502 and the first piston 802 to move up and down. Simultaneously, as the first piston 802 moves upward, the second block 811 blocks the passage between the second connecting groove 809 and the pressure chamber 803. At the same time, a negative pressure will be generated inside the first connecting groove 806, causing the first block 807 to move away from the bottom end of the first connecting pipe 805, allowing the water-oil mixture inside the oil tank 6 to pass through the first connecting groove 805. The pipe 805 and the first connecting groove 806 are drawn into the pressure chamber 803. When the first piston 802 moves downward, the channel between the first connecting pipe 805 and the first connecting groove is blocked by the first plug. Then, the water-oil mixture in the pressure chamber 803 pushes the second plug, passes through the hole groove inside the second plug, and enters the second connecting pipe 812 and the sedimentation cylinder 813. This allows the water-oil mixture in the oil tank 6 to be continuously transported to the sedimentation cylinder 813. The water settles in the sedimentation cylinder 813, and the oil on the upper layer of the sedimentation cylinder 813 is filtered through the filter screen 817 and then flows back to the oil tank 6 through the third connecting pipe 819, leaving the water in the oil tank 6 inside the sedimentation cylinder 813. The outer wall of the sedimentation tank 813 is provided with a transparent observation window. When the water level inside the sedimentation tank 813 is high, by pulling down the pull block 818, the pull block 818 can move the lifting block 814 downward through the connecting rod 816. The side wall of the lifting block 814 will block the connection channel between the third connecting pipe 819 and the sedimentation tank 813. At the same time, the lifting block 814 will squeeze the water inside the sedimentation tank 813 downward, so that the water inside the sedimentation tank 813 can flow in the opposite direction to flush the filter screen 817, and push open the third block 821, so that the water and impurities inside the sedimentation tank 813 can enter the drain chamber 820 and the drain outlet 825. Finally, the water can be quickly discharged through the drain outlet 825, reducing the oil-water mixing inside the oil tank 6.
[0021] Example 3: Please refer to Figure 1-9The present invention provides a technical solution: one end of the oil tank 6 is fixedly connected to the slide groove 901, the inside of the slide groove 901 is connected to the inside of the oil tank 6, the slide groove 901 is slidably and tightly fitted to the inside of the sleeve 902, the outer wall of the slide groove 901 is provided with a hole groove, the hole groove of the outer wall of the slide groove 901 is aligned with the hole groove of the outer wall of the sleeve 902 through sliding fit, the outer wall of the sleeve 902 is provided with a filter tube 903, the surface of the filter tube 903 is provided with filter holes aligned with the hole groove of the surface of the sleeve 902, the bottom of the slide groove 901 is connected to the slide tube 904, one bottom end of the slide tube 904 is slidably in contact with the inner wall of the compensation tube 905, one bottom end of the compensation tube 905 is fixedly connected to the base plate 505, the inside of the compensation tube 905 is provided with a piston block 907, the top and bottom of the piston block 907 are both provided with a sixth spring 906, one top end of the compensation tube 905 is fixedly connected to the bottom of the sleeve 902; The vibration generated during operation of this implementation scheme can drive the slide 901 to move up and down. The interior of the slide 901 is connected to the interior of the oil tank 6. By sliding up and down, the groove on the outer wall of the slide 901 can be aligned with the groove on the outer wall of the sleeve 902, so that external air can enter the interior of the oil tank 6, avoiding the negative pressure caused by the oil being drawn out of the oil tank 6. When the diesel unit stops working, the slide 901 cannot slide up and down, which causes the groove on the outer wall of the slide 901 to be misaligned with the groove on the outer wall of the sleeve 902, thus helping to reduce the entry of moisture from the external air into the interior of the oil tank 6. When the temperature difference between day and night causes the interior of the oil tank 6 to have a breathing effect, the piston block 907 will adaptively slide up and down to adjust its position according to the pressure inside the oil tank 6, thereby balancing the pressure inside the oil tank 6.
