[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Embodiment 1, by Figures 1 to 8The present invention provides a box-type generator set with a closed ventilation function, comprising a box body 1, a generator body 2 is fixedly arranged inside the box body 1, an air inlet 3 is opened at one end of the box body 1, an air inlet opening and closing mechanism 4 is fixedly arranged at one end of the box body 1 near the air inlet 3, an air exhaust port 5 is opened at the other end of the box body 1, a support frame 6 is fixedly arranged at one end of the box body 1 near the air exhaust port 5, an inner cavity 7 is formed between the support frame 6 and the box body 1, an exhaust opening and closing mechanism 8 is fixedly arranged inside the inner cavity 7, the air inlet opening and closing mechanism 4 and the exhaust opening and closing mechanism 8 are both composed of a driving component 9 and a plurality of opening and closing units 10, and the opening and closing units 10 and the driving component The driving assembly 9 is composed of two cylinders 11 and a supporting grid 12, the supporting grid 12 is fixedly connected to one end of the cylinder 11, the opening and closing unit 10 is composed of an air guide sleeve 13, a plurality of pulling modules 14, a blocking cone 15, a connecting short arm 16 and a plurality of blocking valve plates 17, the air guide sleeve 13 is fixedly connected to the box body 1 and the supporting frame 6 respectively, the pulling module 14 is fixedly connected to the inside of the air guide sleeve 13, the blocking cone 15 is fixedly connected to the supporting grid 12 through the connecting short arm 16, a plurality of air ducts 18 are opened inside the blocking cone 15, and the blocking valve plate 17 is rotatably connected to the inside of the air duct 18 and connected to the pulling module 14;

[0034] When in use, heat dissipation is achieved through the air inlet 3, and hot air is discharged through the exhaust port 5. The air inlet opening and closing mechanism 4 and the exhaust opening and closing mechanism 8 are connected to the controller on the generator body 2, and synchronous control is achieved through the controller of the generator body 2, so that when the generator body 2 is closed or used outdoors on rainy days, the air inlet 3 and the exhaust port 5 are closed through the air inlet opening and closing mechanism 4 and the exhaust opening and closing mechanism 8. When used on rainy days, since the air cooling channel is closed, heat can be dissipated through the liquid cooling mechanism built into the generator set. At the same time, rainwater can dissipate heat from the box body 1 to achieve an auxiliary heat dissipation function. During ventilation, the cylinder 11 drives the support grid 12 to move, and the support grid 12 carries The movable connecting short arm 16 moves, and the connecting short arm 16 drives the blocking cone 15 to move, so that the blocking cone 15 is separated from the air guide sleeve 13. At this time, the pulling module 14 generates a pulling force on the blocking valve plate 17, and the blocking valve plate 17 rotates 90 degrees under the pulling force. The blocking valve plate 17 is in a horizontal state at this time, so that the air duct 18 is in a conducting state, and air intake and exhaust can be realized normally. When closing, the cylinder 11 contracts and resets, and the pulling module 14 releases the pulling force on the blocking valve plate 17, and the reset operation is realized through the self-resetting function of the blocking valve plate 17. The blocking valve plate 17 is in a vertical state at this time, so that the air duct 18 is closed, thereby realizing the blocking of air intake and exhaust;

[0035] The pulling module 14 is composed of a support plate 19, a strip limit frame 20, a tension spring 21, a slider 22, a connecting ring 23 and a pulling rope 24.

The setting of the tension spring 21 can extend the travel of the slider 22 and the pulling rope 24, so that they can adapt to the blocking valve plate 17;

[0037] The blocking valve plate 17 is composed of a plate body 25, a rotating shaft 26, a scroll return spring 27 and a second connecting ring 28.

The second connecting ring 28 is fixedly connected to the side of the plate body 25 and is fixedly connected to the other end of the pulling rope 24.

[0038] When the plate body 25 is subjected to a pulling force, it rotates around the central axis of the rotating shaft 26, at which time the scroll return spring 27 contracts. When the pulling force is released, the scroll return spring 27 drives the rotating shaft 26 to automatically return to its original position, thereby driving the plate body 25 to automatically return to its original position.

[0039] Embodiment 2, based on embodiment 1, Figures 4 to 8 It is shown that a plurality of limiting guide rods 29 are fixedly provided on the box body 1 and the support frame 6.

The protective net 39 can provide safety protection for the exhaust port 5. The cleaning component 40 can clean the air inlet filter 38 to prevent excessive dust on the air inlet filter 38 from affecting the air intake effect.
