Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1, consists of Figures 1 to 9Provided is a movable diesel generator set of the present invention, which includes a support bottom plate 1, a housing 2, and a generator set body 3. Both the housing 2 and the generator set body 3 are connected to the top end of the support bottom plate 1. A support plate 4 is welded to the bottom end of the generator set body 3. The support plate 4 and the support bottom plate 1 are connected by a plurality of shock absorbers 5. Two L-shaped limit plates 6 are fixedly arranged at both ends of the support plate 4. Moving support mechanisms 7 are fixedly arranged at the four corners of the top end of the support bottom plate 1. An auxiliary heat dissipation mechanism 8 is fixedly arranged at the middle position of one end of the top of the support bottom plate 1. The auxiliary heat dissipation mechanism 8 is in close connection with the outer side wall of the diesel engine of the generator set body 3;

[0035] During use, the shock absorbers 5 can improve the shock absorption performance of the generator set body 3 during operation, avoiding excessive vibration amplitude and affecting the working stability. The moving support mechanisms 7 can facilitate the overall movement of the diesel generator set. During the movement, the L-shaped limit plates 6 and the moving support mechanisms 7 form a limiting effect, avoiding the deviation of the generator set body 3 and improving the overall stability and safety of the generator set body 3. The auxiliary heat dissipation mechanism 8 can realize the auxiliary heat dissipation of the diesel engine on the generator set body 3;

[0036] The moving 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 end of the support bottom 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 penetrates through the L-shaped limit plate 6. The universal wheel 13 is fixedly connected to the bottom end of the L-shaped support 11;

[0037] When it is necessary to move the diesel generator set, 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 support function is realized through the universal wheel 13, thus facilitating the movement of the diesel generator set. During the downward movement of the L-shaped limit arm 12, it will insert into the L-shaped limit plate 6 and the support bottom plate 1, thereby realizing the limiting effect. The L-shaped limit plate 6 realizes the limit on the support plate 4, and the support plate 4 realizes the limit on the generator set body 3, improving the overall stability of the generator set body 3;

[0038] The shock absorber 5 is composed of an upper connecting plate 14, a lower connecting plate 15, a plurality of shock 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 support bottom plate 1. The shock springs 16 and the damper 17 are both fixedly connected between the upper connecting plate 14 and the lower connecting plate 15;

[0039] When the shock absorber 5 works, the shock springs 16 realize the shock absorption and buffering function, and the damper 17 plays a damping role, avoiding excessive deformation of the shock springs 16 and affecting the stability;

[0040] The damper 17 is composed of a piston cylinder 18, a piston plate 19, a support column 20, two plug columns 21 and two flow resistance plates 22. The piston cylinder 18 is fixedly connected to the lower connecting plate 15. The piston plate 19 is slidably connected inside the piston cylinder 18. Two oil holes 23 matching the plug columns 21 are formed in the piston plate 19. The support column 20 is slidably inserted through the top end of the piston cylinder 18 and fixedly connected between the piston plate 19 and the upper connecting plate 14. The plug column 21 is fixedly connected to the bottom end inside the piston cylinder 18. The diameter of the plug column 21 is smaller than the inner diameter of the oil hole 23. The flow resistance plate 22 is rotatably connected to the top end of the piston plate 19 through a spring shaft 24. The inside of the piston cylinder 18 is filled with hydraulic oil 25. The flow resistance plate 22 is used to partially block the oil hole 23 under the pushing action of the hydraulic oil 25;

[0041] When the damper 17 works, 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 primary stage, the distance between the oil hole 23 and the plug column 21 is relatively far, and the oil intake of the oil hole 23 is relatively large, so as to improve the buffering effect under the combined action of the shock absorption spring 16. During the continuous downward movement of the piston plate 19, the plug column 21 will enter the inside of the oil hole 23 to partially block the oil hole 23, reduce the oil intake of the oil hole 23, thus avoiding the rapid downward movement of the piston plate 19, further reducing the downward movement amplitude and improving the stability. In addition, when the piston plate 19 moves downward, the flow resistance plate 22 will be blocked and rotate to avoid generating an obstructive effect. When the piston plate 19 moves upward and resets, the flow resistance plate 22 is attached to the top surface of the piston plate 19 under the elastic force of the spring shaft 24 and the pushing action of the hydraulic oil 25 to partially block the oil hole 23 and avoid excessive oil return amount from affecting the stability;

[0042] A first limiting hole 26 matching the L-shaped limiting arm 12 is formed in the L-shaped limiting plate 6. Four corners at the top end of the support bottom plate 1 are respectively provided with a second limiting hole 27 matching the L-shaped limiting arm 12 and a mounting groove 28 matching the universal wheel 13;

[0043] 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 the stability. The mounting groove 28 can accommodate the universal wheel 13;

[0044] The bottom end of the piston cylinder 18 is embedded in the top end of the support bottom plate 1, which can make the piston cylinder 18 and the support bottom plate 1 form a limiting effect. The upper connecting plate 14 is connected to the support plate 4 through bolts, and the lower connecting plate 15 is connected to the support bottom plate 1 through bolts, which can improve the connection stability;

[0045] Inner grooves 29 matching the flow baffle 22 are provided at the bottom ends on both sides of the support column 20, which can accommodate the flow baffle 22. The rotation angle range of the flow baffle 22 is 0 - 90 degrees, which can increase the movement range. The flow baffle 22 is located at the side of the top end of the oil hole 23, and can block the oil hole 23;

[0046] The top end of the plug column 21 is of a conical structure, and the diameter of the cylindrical part of the plug column 21 is smaller than the inner diameter of the oil hole 23;

[0047] The top end of the plug column 21 is of a conical structure, which can form a gradual blockage to avoid sudden blockage and oscillation. The diameter of the cylindrical part of the plug column 21 is smaller than the inner diameter of the oil hole 23, which can avoid completely blocking the oil hole 23;

[0048] An air inlet 30 is provided at one end of the outer housing 2, and an air outlet 31 is provided at the other end of the outer housing 2. Protective net plates are provided inside both the air inlet 30 and the air outlet 31. The protective net plates are of a detachable structure. Through the air inlet 30 and the air outlet 31, air intake and exhaust can be realized, and thus air cooling can be realized;

The water pump 33 is fixedly connected to the top end of the water tank 32. The air inlet cooling coil 35 is connected to one end of the generator set body 3. The first water supply pipe 34 is connected between the water pump 33 and the air inlet cooling coil 35. The evaporation cooling component 37 is connected to the side of the diesel engine on the generator set body 3. The second water supply pipe 36 is connected between the air inlet cooling coil 35 and the evaporation cooling component 37;

[0050] When the auxiliary heat dissipation mechanism 8 works, water and ice cubes can be added into the water tank 32. The water pump 33 pumps the ice water and makes the ice water enter into the first water supply pipe 34, the air inlet cooling coil 35 and the second water supply pipe 36. The air inlet cooling coil 35 is installed on the air inlet side of the heat dissipation fan at one end of the generator set body 3, so as to cool and lower the temperature of the incoming air, reduce the incoming air temperature, and thus improve the air cooling effect. The water inside the air inlet cooling coil 35 enters into the evaporation cooling component 37 through the second water supply pipe 36, and absorbs heat through evaporation, and thus realizes auxiliary heat dissipation and temperature reduction;

[0051] The evaporative cooling assembly 37 is composed of a box body 38, a steam discharge pipe 39, a number 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 arranged between the box body 38 and the generator set body 3. The second water supply pipe 36 extends into the interior of the box body 38.

The steam discharge pipe 39 is fixedly connected to the top of the box body 38;

[0052] The water inside the second water supply pipe 36 enters the interior of the jet pipes 40 and then is ejected through the injection micropores 43 on the side of the jet pipes 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 evaporated, and the evaporation process realizes rapid heat absorption. The fan 41 can accelerate the steam flow, so that the steam is discharged to the outside through the steam discharge pipe 39, avoiding the steam from affecting the electronic components inside the generator set. The sealing gasket 42 can improve the connection tightness and prevent water leakage;

[0053] The water tank 32 is connected to the support bottom plate 1 through the mounting clamp 44, which can improve the connection stability of the water tank 32. An inlet 45 is opened at the top of the water tank 32, which is convenient for adding water and ice cubes into the water tank 32;

Aluminum fins 47 are fixedly arranged on the side of the intake air cooling coil 35, which can realize the accelerated cooling of the intake air.

[0055] During work, 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, it is possible to facilitate the movement of the generator set, improve the convenience of movement. When the movement is not required, the universal wheel can be stored to avoid continuous stress on the universal wheel, which affects its service life. This also improves the working stability of the diesel generator set. By setting up an L-shaped limit plate, it can form a limiting effect with the mobile support mechanism during movement, thereby realizing the limitation of the pallet, and further limiting the generator set body to prevent the generator set body from shifting during movement, which affects safety. By setting up a shock absorber composed of an upper connecting plate, a lower connecting plate, several shock springs, and a damper, it can improve the shock absorption performance of the generator set body during operation.
