[0018] Embodiment 1, by Figures 1 to 9The present invention provides a movable diesel generator set, comprising a supporting base plate 1, an outer shell 2 and a generator set body 3, wherein the outer shell 2 and the generator set body 3 are both connected to the top of the supporting base plate 1, a support plate 4 is welded at the bottom end of the generator set body 3, the support plate 4 and the supporting base plate 1 are connected via a plurality of shock absorbers 5, two L-shaped limit plates 6 are fixedly arranged at both ends of the support plate 4, a movable supporting mechanism 7 is fixedly arranged at the four corners of the top end of the supporting base plate 1, an auxiliary heat dissipation mechanism 8 is fixedly arranged at the middle position of one end of the top of the supporting base plate 1, and the auxiliary heat dissipation mechanism 8 is fitted and connected to the outer wall of the diesel engine of the generator set body 3; When in use, the shock absorber 5 can improve the shock absorption performance of the generator set body 3 during operation, avoiding excessive vibration amplitude affecting the working stability. The mobile support mechanism 7 can facilitate the overall movement of the diesel generator set. During the movement, the L-shaped limit plate 6 and the mobile support mechanism 7 form a limit effect to avoid causing the generator set body 3 to deviate, thereby improving the overall stability and safety of the generator set body 3. The auxiliary heat dissipation mechanism 8 can realize auxiliary heat dissipation of the diesel engine on the generator set body 3; The mobile support mechanism 7 is composed of a Z-shaped bracket 9, a hydraulic rod 10, an L-shaped support 11, an L-shaped limit arm 12 and a universal wheel 13. The Z-shaped bracket 9 is welded to the top of the support base plate 1, the hydraulic rod 10 is fixedly connected to the Z-shaped bracket 9, the L-shaped support 11 is fixedly connected to the bottom end of the hydraulic rod 10, the L-shaped limit arm 12 is fixedly connected to one side of the L-shaped support 11 and inserted into the L-shaped limit plate 6, and the universal wheel 13 is fixedly connected to the bottom end of the L-shaped support 11; When the diesel generator set needs to be moved, the hydraulic rod 10 drives the L-shaped support 11, the L-shaped limit arm 12 and the universal wheel 13 to move downward as a whole, so that the universal wheel 13 contacts the ground. At this time, the universal wheel 13 realizes the supporting effect, so as to facilitate the movement of the diesel generator set. The L-shaped limit arm 12 will be inserted into the L-shaped limit plate 6 and the supporting bottom plate 1 during the descending process, so as to realize the limiting effect. The L-shaped limit plate 6 realizes the limiting of the supporting plate 4, and the supporting plate 4 realizes the limiting of the generator set body 3, thereby improving the overall stability of the generator set body 3; The shock absorber 5 is composed of an upper connecting plate 14, a lower connecting plate 15, a plurality of shock absorbing springs 16 and a damper 17. The upper connecting plate 14 is fixedly connected to the bottom end of the support plate 4, the lower connecting plate 15 is fixedly connected to the top end of the supporting bottom plate 1, and the shock absorbing springs 16 and the damper 17 are fixedly connected between the upper connecting plate 14 and the lower connecting plate 15; When the shock absorber 5 is working, the shock absorbing spring 16 realizes the shock absorbing and buffering effect, and the damper 17 plays a damping role to prevent the shock absorbing spring 16 from deforming too much and affecting the stability; The damper 17 is composed of a piston cylinder 18, a piston plate 19, a support column 20, two plugs 21 and two baffles 22. The piston cylinder 18 is fixedly connected to the lower connecting plate 15, the piston plate 19 is slidably connected to the inside of the piston cylinder 18, and two oil holes 23 matching the plugs 21 are provided on the piston plate 19. The support column 20 is slidably inserted into the top of the piston cylinder 18 and fixedly connected between the piston plate 19 and the upper connecting plate 14. The plug 21 is fixedly connected to the bottom end of the piston cylinder 18. The diameter of the plug 21 is smaller than the inner diameter of the oil hole 23. The baffle 22 is rotatably connected to the top of the piston plate 19 through a spring shaft 24. The interior of the piston cylinder 18 is filled with hydraulic oil 25. The baffle 22 is used to partially block the oil hole 23 under the push of the hydraulic oil 25. When the damper 17 is working, the support column 20 moves downward under pressure, and drives the piston plate 19 to move downward. The piston plate 19 squeezes the hydraulic oil 25. At this time, the hydraulic oil 25 moves upward along the oil hole 23. In the initial stage, the oil hole 23 is far away from the plug 21, and the oil inlet amount of the oil hole 23 is large, so that the buffering effect can be improved under the joint action of the shock absorbing spring 16. When the piston plate 19 continues to move downward, the plug 21 will enter the interior of the oil hole 23 to achieve partial sealing of the oil hole 23. The oil inlet of the oil hole 23 is blocked, thereby preventing the piston plate 19 from moving downward quickly, thereby reducing the downward movement amplitude and improving stability. In addition, when the piston plate 19 moves downward, the spoiler 22 will rotate due to resistance to avoid obstruction. When the piston plate 19 moves upward and resets, the spoiler 22 is pressed against the top surface of the piston plate 19 by the elastic force of the spring shaft 24 and the pushing effect of the hydraulic oil 25, thereby partially blocking the oil hole 23 and preventing the excessive amount of oil return from affecting stability. The L-shaped limiting plate 6 is provided with a limiting hole 26 matching the L-shaped limiting arm 12, and the four corners of the top of the supporting base plate 1 are provided with a limiting hole 27 matching the L-shaped limiting arm 12 and a mounting groove 28 matching the universal wheel 13; The first limiting hole 26 and the second limiting hole 27 can be connected with the L-shaped limiting arm 12 to form a limiting effect, thereby improving stability, and the mounting groove 28 can accommodate the universal wheel 13; The bottom end of the piston cylinder 18 is embedded in the top end of the support bottom plate 1, so that the piston cylinder 18 and the support bottom plate 1 form a limiting effect. The upper connecting plate 14 and the lower connecting plate 15 are connected to the support plate 4 and the support bottom plate 1 by bolts, which can improve the connection stability. The bottom ends of both sides of the support column 20 are provided with inner grooves 29 matching with the spoiler 22, which can accommodate the spoiler 22. The rotation angle range of the spoiler 22 is 0-90 degrees, which can increase the range of movement. The spoiler 22 is located on the side of the top of the oil hole 23, which can achieve the blocking of the oil hole 23. The top end of the plug 21 is a conical structure, and the diameter of the cylindrical part of the plug 21 is smaller than the inner diameter of the oil hole 23; The top of the plug 21 is a conical structure, which can form a gradual blocking effect to avoid sudden blocking and shock. The diameter of the cylindrical part of the plug 21 is smaller than the inner diameter of the oil hole 23, which can avoid complete blocking of the oil hole 23. An air inlet 30 is provided at one end of the outer shell 2, and an air outlet 31 is provided at the other end of the outer shell 2. Protective mesh plates are provided inside the air inlet 30 and the air outlet 31. The protective mesh plates are detachable structures.

The auxiliary heat dissipation mechanism 8 is composed of a water tank 32, a water pump 33, a water supply pipe 1 34, an air inlet cooling coil 35, a water supply pipe 2 36 and an evaporative cooling assembly 37. The water pump 33 is fixedly connected to the top of the water tank 32, the air inlet cooling coil 35 is connected to one end of the generator set body 3, the water supply pipe 1 34 is connected between the water pump 33 and the air inlet cooling coil 35, the evaporative cooling assembly 37 is connected to the side of the diesel engine on the generator set body 3, and the water supply pipe 2 36 is connected between the air inlet cooling coil 35 and the evaporative cooling assembly 37; When the auxiliary heat dissipation mechanism 8 is working, water and ice cubes can be added to the water tank 32, and the water pump 33 extracts ice water and allows the ice water to enter the water supply pipe 1 34, the air inlet cooling coil 35 and the water supply pipe 2 36. The air inlet cooling coil 35 is installed on the air inlet side of the cooling fan at one end of the generator body 3, so as to cool the air inlet, reduce the air inlet temperature, and thus improve the air cooling effect. The water inside the air inlet cooling coil 35 enters the evaporative cooling component 37 through the water supply pipe 2 36, absorbs heat through evaporation, and thus achieves auxiliary heat dissipation and cooling; The evaporative cooling assembly 37 is composed of a box body 38, a steam exhaust pipe 39, a plurality of jet pipes 40 and a fan 41. The side of the box body 38 close to the generator set body 3 is an open structure. The box body 38 is connected to the generator set body 3 by bolts. A sealing gasket 42 is provided between the box body 38 and the generator set body 3. The second water supply pipe 36 extends to the inside of the box body 38.

The steam exhaust pipe 39 is fixedly connected to the top of the box body 38. The water in the water supply pipe 36 enters the inside of the jet pipe 40, and then is ejected through the ejection micropores 43 on the side of the jet pipe 40. The ejected water mist directly contacts the side wall of the diesel engine on the generator set body 3. At this time, the water mist is quickly heated and evaporates, and the evaporation process achieves rapid heat absorption. The fan 41 can accelerate the flow of steam, so that the steam is discharged to the outside through the steam exhaust pipe 39 to prevent the steam from affecting the electronic components inside the generator set. The sealing gasket 42 can improve the connection sealing and avoid water leakage. The water tank 32 is connected to the support base plate 1 by means of a mounting base 44, which can improve the connection stability of the water tank 32. A water inlet 45 is provided at the top of the water tank 32, which is convenient for adding water and ice cubes into the water tank 32. The air inlet cooling coil 35 is connected to the generator set body 3 through a plurality of jackets 46, so that the air inlet cooling coil 35 can be reinforced and installed. Aluminum fins 47 are fixedly provided on the side of the air inlet cooling coil 35, so as to accelerate the cooling of the air inlet.

[0019] During operation, by setting up a mobile support mechanism composed of a Z-shaped bracket, a hydraulic rod, an L-shaped support, an L-shaped limit arm and a universal wheel, the generator set can be easily moved, thereby improving the convenience of movement. When it is not needed to be moved, the universal wheel can be stored to avoid continuous force on the universal wheel and affecting its service life. The working stability of the diesel generator set is also improved. By setting up an L-shaped limit plate, a limiting effect can be formed with the mobile support mechanism during movement, thereby limiting the support plate, and then limiting the generator set body, thereby avoiding the generator set body from being offset during movement and affecting safety. By setting a shock absorber composed of an upper connecting plate, a lower connecting plate, a plurality of shock absorbing springs and a damper, the generator set can be improved. The shock-absorbing performance of the main body when working can be improved by setting a damper composed of a piston cylinder, a piston plate, a support column, two plugs and two baffles, so as to avoid a large range of movement of the generator set body and further improve the shock-absorbing effect; by setting an auxiliary heat dissipation mechanism composed of a water tank, a water pump, a water supply pipe one, an air inlet cooling coil, a water supply pipe two and an evaporative cooling component, cold water or ice water can be used for auxiliary cooling. On the one hand, the air inlet cooling coil can be used to cool the air intake, thereby improving the air cooling effect. By setting an evaporative cooling component composed of a box body, a steam exhaust pipe, a plurality of jet pipes and a fan, the evaporative heat absorption performance of water can be used to achieve auxiliary cooling and temperature reduction, so as to avoid the temperature of the generator set body being too high and affecting the working stability and service life.
