The transfer case 1 is installed on the diesel generator set 100 and is in transmission connection with the diesel engine in the diesel generator set 100. The erection drive mechanism 2 is respectively connected to the transfer case 1 and the heat dissipation unit 3. The power of the diesel engine in the diesel generator set 100 is transmitted to the erection drive mechanism 2 through the transfer case 1, and the heat dissipation unit 3 is controlled to be erected or retracted through the erection drive mechanism 2. Compared with the prior art in which the heat dissipation structure is fixedly installed with the diesel generator set 100 as an integral structure, by controlling the heat dissipation unit 3 to be erected through the erection drive mechanism 2, the ventilation efficiency of the heat dissipation unit 3 can be improved, thereby improving the heat dissipation efficiency of the heat dissipation unit 3 and the cooling rate of the heat dissipation structure for the diesel generator set 100, effectively ensuring the long-term stable operation of the diesel generator set 100.

[0048] Preferably, as Figure 2 shown, the erection drive mechanism 2 includes a support rod 21, a sliding seat 22, and a lead screw 23. Both ends of the support rod 21 are hinged to the sliding seat 22 and the heat dissipation unit 3 respectively.

[0072] Preferably, as Figure 15As shown, the fixed pin assembly 663 includes a fixed pin 6631, a fixed pin return spring 6632, and a fixed pin hole end cap 6633. The fixed pin hole end cap 6633 is buckled at the end of the fixed pin hole 624 and can be used to prevent foreign objects from entering the fixed pin hole 624. The fixed pin 6631 is inserted into the fixed pin hole 624 in the fixed seat 62 and is slidably connected to the fixed pin hole 624. The fixed pin 6631 includes a fixed end head, a pushing portion, and a connecting rod that are fixedly connected in sequence. By applying a pushing force to the pushing portion in the fixed pin 6631 through the push rod 6621, the fixed pin 6631 is moved along the axis of the fixed pin hole 624, and then the fixed end head is withdrawn from the fixed hole 631 in the magnetic isolation sheet 63, so as to release the locking of the magnetic isolation sheet 63. The fixed pin return spring 6632 is sleeved on the connecting rod of the fixed pin 6631. One end of it is fixedly connected to the pushing portion, and the other end is fixedly connected to the fixed pin hole end cap 6633. The fixed pin return spring 6632 is used to apply an elastic force and a torsion force to the fixed pin 6631, so that the fixed pin 6631 maintains the potential energy to return to the initial position. When the fixed pin 6631 is rotated to release the limit of the push rod 6621 on the fixed pin 6631, the fixed pin 6631 quickly returns to the position under the action of the elastic force and torsion force of the fixed pin return spring 6632. That is, under the action of the elastic force of the fixed pin return spring 6632, the fixed end head of the fixed pin 6631 can tightly press the unlocked magnetic isolation sheet 63 to prevent the magnetic isolation sheet 63 from freely rotating and avoid the magnetic isolation sheet 63 from turning out of the gap between the first magnet 641 and the second magnet 622, thereby realizing the stability of locking and fixing the erected and unfolded heat dissipation unit 3. Or after the magnetic isolation sheet 63 returns to the initial position, the fixed end head of the fixed pin 6631 is inserted into the fixed hole 631 to lock the magnetic isolation sheet 63. At the same time, under the action of the torsion force of the fixed pin return spring 6632, the fixed pin 6631 rotates back to the initial position.

[0073] Preferably, the fixed pin assembly 663 further includes a knob 6634. The knob 6634 is detachably connected to the other end of the connecting rod in the fixed pin 6631. By screwing the knob 6634, the fixed pin 6631 can be conveniently rotated, so as to release the limit of the push rod 6621 on the fixed pin 6631, and the fixed pin 6631 quickly returns to the position under the action of the elastic force and torsion force of the fixed pin return spring 6632.

[0074] Preferably, an annular gasket is provided on the fixed pin return spring 6632. The annular gasket is fixedly installed at the end of the fixed pin return spring 6632 and is fixedly connected to the pushing portion in the fixed pin 6631.

[0075] Preferably, as Figure 16As shown, the fixing pin 6631 includes a pushing portion. The pushing portion includes a first avoidance groove 66311, a second avoidance groove 66312, and a wedge-shaped protrusion 66313. For the first avoidance groove 66311 and the second avoidance groove 66312, the first avoidance groove 66311 is used to avoid the push rod 6621 when the wedge-shaped protrusion 66313 is pushed to move; the second avoidance groove 66312 is used to avoid the push rod 6621 when the limit of the fixing pin 6631 is released, so as to realize the release of the limit of the push rod 6621 on the fixing pin 6631, that is, the limit effect of the push rod 6621 on the fixing pin 6631 can be released after the pushing portion rotates a certain angle (preferably 90° angle); the wedge-shaped protrusion 66313 is fixedly installed in the first avoidance groove 66311 and is used to contact the pushing end in the push rod 6621. The pushing end slides along the inclined surface of the wedge-shaped protrusion 66313, so as to push the fixing pin 6631 to move away from the magnetic shielding sheet 63 along the axis of the fixing pin hole 624.

[0076] As described above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
