Description

Technical Field

[0001] The present invention relates to the field of generator technology, in particular to a vehicle-mounted diesel generator set with a temperature management mechanism. Background Art

[0002] A vehicle-mounted diesel generator set is a small, independent power generation device, mainly composed of a diesel engine, a generator and a control system. It uses the mechanical energy generated by diesel combustion to drive the generator, and converts mechanical energy into electrical energy through the principle of electromagnetic induction, thereby providing power support for various equipment. Diesel burns in the engine cylinder to produce high-temperature and high-pressure gas, which pushes the piston to reciprocate. The linear motion of the piston is converted into rotational motion through the connecting rod and crankshaft, driving the generator rotor to rotate. When the generator rotor rotates, it cuts the magnetic field of the stator winding, generates induced current, and thus outputs electrical energy.

[0003] Diesel burns in the engine cylinder, generating high-temperature, high-pressure gas that pushes the piston to do work. During this process, part of the heat released by combustion is converted into mechanical energy, and the other part is dissipated in the form of heat energy. High temperature will cause the power output of the diesel generator to decrease. In a high temperature environment, the gas density in the cylinder decreases and the combustion efficiency decreases. High temperature may also affect the performance of the cooling system, causing the coolant temperature to be too high, further affecting the efficiency of the generator. Summary of the Invention

[0004] The object of the present invention is to provide a vehicle-mounted diesel generator set with a temperature management mechanism to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a vehicle-mounted diesel generator set with a temperature management mechanism, comprising a protective cover, a generator disposed within the protective cover, electric push rods disposed above and below the generator within the protective cover, the electric push rods being fixedly mounted on the protective cover via auxiliary fixing brackets;

A rectangular sleeve is movably sleeved outside the water pipe, and a fixed end plate is fixedly installed inside the rectangular sleeve. An elastic water pumping member is provided between the fixed end plate and the water pipe for connection. A water pump is fixedly installed on the inner and outer walls of the rectangular sleeve, and the water pump and the elastic water pumping member are connected to each other.

[0008] One end of the water pump away from the rectangular sleeve is connected to a water flow cooling component, and a side cooling plate is provided on the outer wall of the water flow cooling component. The side cooling plates are electrically connected through connecting wires.

[0009] Preferably, an air pressure balancing valve is provided at the last position of the water flow cooling element, and the air pressure balancing valve is used to balance the pressure inside the water flow cooling element.

[0010] Preferably, the top of the water flow cooling element is fixedly mounted on the inner wall of the protective cover via a fixed mounting seat.

[0011] Preferably, the cross section of the water flow cooling element is wavy, and reducing the thickness of the water flow cooling element improves the cooling effect of the side cooling plate on the unit water flow cooling element.

[0012] Preferably, a plurality of groups of heat dissipating fins are equidistantly arranged on the outer wall of the arc-shaped cooling hollow member.

[0013] Preferably, an auxiliary assembly frame is provided outside the protective cover for protection, a hollow tube is fixedly installed on the auxiliary assembly frame, a vertical lifting plate is vertically and movably installed in the hollow tube, a pressure plate is fixedly installed at the bottom of the generator, and a pressure ball is provided at the bottom of the pressure plate;

[0014] A fixed shaft frame is fixedly installed on the hollow tube, and a rotating pedal is rotatably connected to the fixed shaft frame. An end of the rotating pedal close to the inner side is located in an auxiliary lifting groove provided on the vertical lifting plate.

[0015] Preferably, the size of the auxiliary lifting groove is larger than the size of the inner end of the rotating pedal, so that the rotating pedal can apply pressure to the vertical lifting plate up and down.

[0016] Preferably, side fixing seats are fixedly installed on both sides of the inner wall of the protective cover, and the side fixing seats are slidably connected to the front and rear movable frames. The front and rear movable frames are slidably connected to the left and right movable frames through the left and right movable grooves. A vertical lifting plate is provided between the left and right movable frames and the front and rear movable frames for elastic connection;

[0017] A limiting end plate is fixedly mounted on the side fixing seat, and the front and rear movable frames are connected to the limiting end plate via a second spring.

[0018] Preferably, the protruding parts of the outer walls of the left and right movable frames are engaged in the left and right movable grooves provided on the front and rear movable frames, and the shapes of the two are adapted to each other.

[0019] Preferably, the side fixing seat and the limiting end plate form a structure to limit the movement of the front and rear movable frames.

[0020] Preferably, the two side fixing seats and the structures on the side fixing seats are arranged in bilateral symmetry.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Suction is generated during the back-and-forth deformation of the arc elastic pumping member, which is used to extract part of the water flow in the arc-shaped cooling hollow member and enter the water pump and the water cooling member. The side cooling plate is used to cool the water cooling member. The water pump is used to pump the cooling water in the water cooling member into the arc-shaped cooling hollow member. The arc-shaped cooling hollow member and the generator exchange heat with each other to reduce the heat generated when the generator is working, thereby assisting in cooling the generator during operation. By effectively lowering the operating temperature of the generator, the energy loss caused by high temperature can be reduced, thereby improving the overall efficiency of the generator. The wavy design significantly increases the surface area of ​​the water cooling member, thereby increasing the contact area with the side cooling plate. A larger contact area means more efficient heat exchange, which can transfer heat from the water flow faster.

[0023] 2. When the vehicle is in motion, uneven roads, cornering, braking, and accelerating can all cause items inside the vehicle to shake. Without effective anchoring, the generator could shake violently, potentially damaging delicate internal electrical components, wiring, or structural parts. The spring system effectively limits this shaking, significantly reducing the risk of damage. The second spring limits the forward, backward, and left-right movement of the movable frame, while the first spring specifically suppresses left-right shaking. The entire system provides a relatively stable operating and storage environment for the generator, helping to maintain its stable posture during transportation or movement.

[0024] 3. The vertical lifting plate and pressure plate descend, allowing the pressure ball to contact the ground, which provides a stable reference point. By stepping on the rotating pedal, the pressure plate is pushed upward. This upward force can be transmitted to the auxiliary assembly frame itself or its contact point with the ground through design, thereby firmly fixing the frame in the designated position and preventing it from moving or shaking during subsequent use. The fixing force is applied by rotating the pedal with the foot, freeing both hands. This allows the operator to complete the fixing step conveniently and quickly after completing the movement and positioning. This is especially important in situations where one hand may be needed to hold or adjust the auxiliary assembly frame, improving the safety and convenience of operation.

[0038] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0039] See also Figures 1 to 12 The present invention provides a technical solution: a vehicle-mounted diesel generator set with a temperature management mechanism, comprising a protective cover 1, a generator 2 is arranged in the protective cover 1, electric push rods 3 are arranged above and below the generator 2 in the protective cover 1, and the electric push rods 3 are fixedly mounted on the protective cover 1 through an auxiliary fixing frame 4;

[0040] A connecting frame 5 is fixedly mounted on the piston rod end of the electric push rod 3, and an arc-shaped cooling hollow member 6 is fixedly mounted on the connecting frame 5. The two arc-shaped cooling hollow members 6 are arranged on the upper and lower sides of the generator 2. The electric push rod 3 drives the arc-shaped cooling hollow members 6 to contact or separate from the outer wall of the generator 2;

[0041] The generator 2 inside the protective cover 1 generates heat during operation. By controlling the extension and retraction of the electric push rod 3, the contact degree and contact time between the arc-shaped cooling hollow member 6 and the outer wall of the generator 2 can be precisely adjusted. This means that the cooling intensity can be actively increased or decreased according to the real-time operating temperature and load conditions of the generator 2, achieving more intelligent and efficient temperature management.

[0042] The arc-shaped cooling hollow member 6 is designed to match the outer wall shape of the generator 2 and can fit more closely. The electric push rod 3 drives the connecting frame 5 to ensure that the arc-shaped cooling hollow member 6 can stably and evenly contact the generator 2, thereby maximizing the heat exchange area, improving the cooling efficiency, and avoiding local overheating.

[0043] Generator 2 generates different amounts of heat under different loads. When the load on generator 2 is low and the heat generated is small, the electric push rod 3 can be controlled to retract slightly, allowing the arc-shaped cooling hollow member 6 to maintain a certain distance from the generator 2. The arc-shaped cooling hollow member 6 does not work and saves energy. When the load on generator 2 is high and the heat generated is large, the electric push rod 3 can be driven to make the arc-shaped cooling hollow member 6 closely contact, enhancing the cooling effect of the arc-shaped cooling hollow member 6. This flexibility allows the cooling system to better adapt to the dynamic working requirements of the generator.

[0044] Since the arc-shaped cooling hollow member 6 is mounted by the electric push rod 3 and the connecting frame 5 and is movable, when the outer wall of the generator 2 needs to be inspected or maintained, or when the arc-shaped cooling hollow member 6 itself needs to be replaced, it can be moved away by controlling the electric push rod 3 without removing too many fixing parts, thereby simplifying the maintenance process.

[0045] The electric push rod 3 is fixed to the protective cover 1 through the auxiliary fixing frame 4, and the entire cooling system is placed inside the protective cover 1, making the entire design more compact and integrated, helping to protect these precision components from the influence of the external environment, and also making the layout inside the protective cover 1 neater.

[0046] A water pipe 7 is fixedly installed on the arc-shaped cooling hollow member 6, and the water pipe 7 is connected to the arc-shaped cooling hollow member 6. A rectangular sleeve 8 is movably sleeved on the outside of the water pipe 7, and a fixed end plate 9 is fixedly installed inside the rectangular sleeve 8. An elastic water pumping member 10 is provided between the fixed end plate 9 and the water pipe 7 for connection. A water pump 11 is fixedly installed on the inner and outer walls of the rectangular sleeve 8, and the water pump 11 and the elastic water pumping member 10 are connected to each other.

[0047] One end of the water pump 11 away from the rectangular sleeve 8 is connected to a water cooling component 12 , and a side cooling plate 13 is provided on the outer wall of the water cooling component 12 . The side cooling plates 13 are electrically connected to each other through connecting wires 14 .

[0048] The curved hollow cooling element 6 is connected to the water flow cooling element 12 via a water pipe 7. A water pump 11 drives the water flow, which is connected and buffered by an elastic pumping element 10, ultimately forming a closed cooling water loop. Water absorbs heat from the generator 2 in the curved hollow cooling element 6, flows through the water pump 11, and is pumped to the water flow cooling element 12. There, the water dissipates heat through the side cooling plates 13, and after cooling, flows back to the curved hollow cooling element 6. This cycle repeats itself, ensuring a continuous and stable cooling effect.

[0049] The curved hollow cooling element 6 is in direct contact with the generator 2, absorbing heat. Driven by a water pump 11, the water cooling element 12 continuously removes hot water from the curved hollow cooling element 6 and dissipates it through side cooling plates 13 on its outer wall. These side cooling plates 13 increase the heat dissipation area, helping to dissipate heat more quickly into the surrounding environment.

[0050] The elastic pumping member 10 is connected between the fixed end plate 9 and the water pipe 7. It not only serves as a connection, but more importantly, it can absorb or buffer pipeline vibrations and small displacements caused by temperature changes, water pump operation or vehicle driving, preventing the pipeline from being damaged due to stress concentration, thereby improving the reliability and durability of the entire system.

[0051] The water pump 11 is an active component that ensures that the cooling water can overcome the flow resistance and circulate continuously in the system. The design of the side cooling plate 13 cooperates with the work of the water pump to provide active heat dissipation capabilities instead of relying solely on natural heat dissipation. This is especially important for the generator 2 operating under high load or high temperature environment.

[0052] An air pressure balancing valve 15 is provided at the end of the water flow cooling element 12 , and the air pressure balancing valve 15 is used to balance the pressure inside the water flow cooling element 12 .

[0053] The cooling water within water cooling element 12 may expand or generate steam due to temperature fluctuations, causing internal pressure to increase. The pressure balancing valve 15 promptly releases excess pressure to prevent damage to the system caused by excessive pressure. When the cooling water temperature drops or the system stops operating, the pressure within water cooling element 12 may decrease, even forming a vacuum. The pressure balancing valve 15 prevents outside air from entering the system, avoiding system failures caused by a vacuum. By maintaining a stable internal pressure, the pressure balancing valve 15 helps maintain the stable operation of the entire cooling system, ensuring that the cooling effect is not affected by pressure fluctuations.

[0054] The top of the water cooling element 12 is fixedly mounted on the inner wall of the protective cover 1 via a fixed mounting seat 16 .

[0055] The cross section of the water flow cooling element 12 is wavy, and reducing the thickness of the water flow cooling element 12 improves the cooling effect of the side cooling plates 13 on the unit water flow cooling element 12 .

[0056] The wavy cross-section may appear to be shorter than a straight cross-section in a certain projection direction, but its tortuous shape actually increases the circumference of the contact interface between the water flow cooling component 12 and the side cooling plate 13. By reducing the wall thickness, heat can be more easily transferred from the internal water flow to the external side cooling plate. The wavy shape increases the contact circumference, provides more heat dissipation channels, and achieves efficient heat dissipation in a limited space.

[0057] A plurality of groups of heat dissipating fins 17 are equidistantly arranged on the outer wall of the arc-shaped cooling hollow member 6 .

[0058] An auxiliary assembly frame 18 is provided outside the protective cover 1 for protection. A hollow tube 19 is fixedly installed on the auxiliary assembly frame 18. A vertical lifting plate 20 is vertically and movably installed inside the hollow tube 19. A pressure plate 21 is fixedly installed at the bottom of the generator 2. A pressure ball 22 is provided at the bottom of the pressure plate 21.

[0059] A fixed shaft frame 23 is fixedly mounted on the hollow tube 19 , and a rotating pedal 24 is rotatably connected to the fixed shaft frame 23 . An inner end of the rotating pedal 24 is located in an auxiliary lifting slot 25 provided on the vertical lifting plate 20 .

[0060] By operating the rotating pedal 24, the vertical lifting plate 20 can be driven to move up and down in the hollow tube 19. The movement of the vertical lifting plate 20 will drive the pressure plate 21 and the pressure ball 22 to rise and fall together. The design of the rotating pedal 24 makes the operation more labor-saving. Using the principle of leverage, the user only needs to apply a small force on the pedal to drive the heavier vertical lifting plate 20 to move. This foot-operated operation method can free up both hands and is convenient for users to use when performing other coordinated operations.

[0061] The auxiliary assembly frame 18 is arranged outside the protective cover 1, which supports and protects the entire operating mechanism and prevents it from being damaged by the external environment. The hollow tube 19 provides precise guidance and a stable lifting channel for the vertical lifting plate 20. The fixed shaft frame 23 ensures the stable rotation of the rotating pedal 24 and forms an integral frame with the hollow tube 19.

[0062] The size of the auxiliary lifting groove 25 is larger than the size of the inner end of the rotating pedal 24 , so that the rotating pedal 24 can apply pressure to the vertical lifting plate 20 up and down.

[0063] Since the auxiliary lifting groove 25 is larger than the inner end of the rotating pedal 24, the inner end of the rotating pedal 24 can completely fall into and stably remain in the groove, which ensures that when the pedal 24 is stepped on or lifted, the inner end of the pedal 24 will not slip out of the groove 25, thereby continuously and stably applying an upward force to the vertical lifting plate 20 or allowing the vertical lifting plate 20 to move downward under its own weight or other effects.

[0064] Side fixing seats 26 are fixedly installed on both sides of the inner wall of the protective cover 1. A front and rear movable frame 27 is slidably connected to the side fixing seat 26. The front and rear movable frame 27 is slidably connected to the left and right movable frame 28 through the left and right movable grooves 29. A vertical lifting plate 20 is provided between the left and right movable frame 28 and the front and rear movable frame 27 for elastic connection.

[0065] A limiting end plate 31 is fixedly mounted on the side fixing seat 26 , and the front and rear movable frames 27 and the limiting end plate 31 are connected via a second spring 32 .

[0066] The side mountings 26 are fixed to the inner wall of the protective cover, providing a basic support point for the entire system. The front and rear movable frames 27 can slide in the front-to-back direction on the side mountings 26, increasing the flexibility of the system. The left and right movable frames 28 can move to a limited extent in the front-to-back and left-to-right directions through the left and right movable slots 29. This design can accommodate slight displacements that may occur in the generator 2 or other connected components, or facilitate adjustment of their precise position. The vertical lifting plate 20 is elastically connected to the left and right movable frames 28. This means that when the left and right movable frames 28 are subjected to external impact or vibration, the elastic connection can absorb some of the energy, reducing the impact directly transmitted to the generator 2 or other precision components.

[0067] The second spring 32 connects the front and rear movable frame 27 and the limiting end plate 31. When the front and rear movable frame 27 moves forward or backward under the action of external force, the spring 32 will be compressed or stretched. When the external force disappears, the elastic force of the spring 32 will push the front and rear movable frame 27 to return to its original position. The limiting end plate 31 limits the moving range of the front and rear movable frame 27 to prevent it from excessive movement causing structural damage or loss of control.

[0068] The protruding portion of the outer wall of the left and right movable frame 28 is engaged in the left and right movable groove 29 provided on the front and rear movable frames 27, and the shapes of the two are adapted to each other.

[0069] The side fixing seat 26 and the limiting end plate 31 form a structure to limit the movement of the front and rear movable frames 27.

[0070] The two side fixing seats 26 and the structures on the side fixing seats 26 are arranged in bilateral symmetry.

[0071] Working principle:

[0072] Step 1: When the auxiliary assembly frame 18 and the components in the auxiliary assembly frame 18 are placed in the vehicle and are driving, the auxiliary assembly frame 18 and the objects in the auxiliary assembly frame 18 will shake. When the objects in the auxiliary assembly frame 18 shake, the generator 2 also shakes. When the generator 2 shakes back and forth, the left and right movable frame 28 and the front and back movable frame 27 are driven to shake back and forth. During the process of shaking back and forth, the left and right movable frame 28 and the front and back movable frame 27 will apply pressure to the second spring 32 to drive the second spring 32 to deform. The elastic force generated by the deformation of the second spring 32 is used to reduce The amplitude of the movement of the front and rear movable frames 27 and the left and right movable frames 28 is such that when the generator 2 shakes left and right, the generator 2 will apply pressure to the left and right movable frames 28 to drive the left and right movable frames 28 to move in the left and right movable grooves 29. At the same time, during the movement of the left and right movable frames 28, pressure will be applied to the first spring 30 to drive the first spring 30 to deform. The deformation of the first spring 30 will apply pressure to the left and right movable frames 28 to reduce the left and right shaking of the generator 2 in the horizontal direction, thereby reducing the impact of the shaking of the auxiliary assembly frame 18 on the generator 2 in the auxiliary assembly frame 18.

[0073] The second step: the connection frame 5 is driven to rise and fall by the operation of the electric push rod 3, thereby driving the arc-shaped cooling hollow member 6 to rise and fall. During the process of the arc-shaped cooling hollow member 6 rising and falling, the distance between the arc-shaped cooling hollow member 6 and the outer wall of the generator 2 becomes larger, and the arc-shaped cooling hollow member 6 is no longer in contact with the generator 2. The cooling liquid in the arc-shaped cooling hollow member 6 no longer cools the generator 2. At the same time, during the process of the arc-shaped cooling hollow member 6 rising and falling, the arc-shaped cooling hollow member 6 will drive the water pipe 7 on the arc-shaped cooling hollow member 6 to move. The water pipe 7 will apply pressure to the elastic pumping member 10 during the movement. The elastic pumping member 10 will generate suction during the back-and-forth deformation process, which is used to extract part of the water flow in the arc-shaped cooling hollow member 6 and enter the water pump 11 and the water flow cooling member 6. In the component 12, the water flow in the water pipe 7 is extracted, and the side cooling plate 13 is powered by connecting the wires 14. The side cooling plate 13 is used to cool the water cooling component 12, thereby assisting in cooling the water flow entering the water cooling component 12. At the same time, when the water flow in the water cooling component 12 reverses and enters the arc-shaped cooling hollow component 6, the water pump 11 is required to work. The water pump 11 is used to pump the cooled water flow in the water cooling component 12 into the arc-shaped cooling hollow component 6. The piston rod of the auxiliary fixing frame 4 drives the arc-shaped cooling hollow component 6 to descend, and the arc-shaped cooling hollow component 6 is in contact with the generator 2, thereby realizing mutual heat exchange between the arc-shaped cooling hollow component 6 and the generator 2, which is used to reduce the heat generated when the generator 2 is working, thereby assisting in cooling the generator 2 during operation.

[0074] Step 3: After the auxiliary assembly frame 18 moves to the designated position, the vertical lifting plate 20 descends in the hollow tube 19. During the descending process of the vertical lifting plate 20 and the pressure plate 21, the pressure ball 22 at the bottom of the pressure plate 21 contacts the ground. Through the contact between the foot and the rotating pedal 24, the rotating pedal 24 rotates on the fixed axis frame 23. The other end of the rotating pedal 24 applies an upward thrust to the vertical lifting plate 20, thereby driving the pressure plate 21 to move upward. After the pressure plate 21 moves upward, the auxiliary assembly frame 18 can move normally, thereby assisting in the fixation of the auxiliary assembly frame 18 after movement.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
