Technical Field

[0001] The utility model relates to the technical field of generator sets, in particular to a rainproof chassis of a generator set. Background Art

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. The generator set consists of a power system, control system, silencer system, shock absorption system, and exhaust system arranged in a box. Currently, generator sets are usually equipped with rain covers to protect the units from rain.

[0003] However, the existing rain cover only protects the unit, but lacks rain protection for the air outlet and door. Rainwater enters through the door seal and air outlet on rainy days, which may cause the generator set to become damp and leak electricity, thereby causing certain losses. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a rainproof box for a generator set.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The top of the two connecting blocks is rotatably connected to the sliding sleeve, and the two sliding sleeves are slidably connected to the sliding rods. One side of the two sliding sleeves is provided with a locking assembly for fixing the sliding rods.

[0009] As a further solution of the present invention, two torsion springs are sleeved on the outer side of the reel, and the two ends of the torsion springs are respectively fixed to the reel and the connecting block.

[0010] As a further solution of the present invention, electric fans are fixedly connected to the two heat dissipation openings.

[0011] As a further solution of the present invention, a protective net for protecting the electric fan is fixedly connected to the two heat dissipation openings.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. 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, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0023] Reference Figures 1-4, a rainproof chassis of a generator set, including a box body 2, a rainproof roof 3 is fixed to the top of the box body 2 by bolts, and two heat dissipation ports are opened on one side of the box body 2, and a fixing block 5 is fixed by bolts on the outer wall of one side of the box body 2 at the bottom position. Two connecting blocks 10 are welded on the outer wall of one side of the box body 2 near the top position, and one side of the two connecting blocks 10 is rotatably connected with a sliding sleeve 13, and the two sliding sleeves 13 are slidably connected with a sliding rod 14. One side of the two sliding sleeves 13 is provided with a locking assembly for fixing the sliding rod 14. A winding shaft 12 is rotatably connected between the two connecting blocks 10, and a tarpaulin 4 is wrapped around the outside of the winding shaft 12. A fixing rod 22 is welded between the two sliding rods 14, and the tarpaulin 4 is fixed to the fixing rod 22. The bottom of the two connecting blocks 10 is rotatably connected with a threaded rod 19, and the outer side of the threaded rod 19 is threadedly connected with a threaded sleeve 23. One side of the threaded sleeve 23 is rotatably connected with a connecting rod 9, and the connecting rod 9 is rotatably connected to the sliding sleeve 13. A locking assembly is provided in the fixing block 5 to fix the sliding rod 14. The two threaded rods 19 are connected by a connecting assembly that rotates synchronously. When one of the threaded rods 19 is rotated, one of the threaded rods 19 will cause the other threaded rod 19 to rotate synchronously through the connecting assembly. During the rotation process, the two threaded rods 19 engage with the threaded sleeve 23 to make the threaded sleeve 23 move upward. During the movement, the threaded sleeve 23 pushes the sliding sleeve 13 to rotate through the connecting rod 9. At the same time, the connecting rod 9 will rotate between the threaded sleeve 23 and the sliding sleeve 13. When the sliding sleeve 13 rotates to a suitable angle, the rotation of the threaded rod 19 is stopped, and then the sliding rod 14 is pulled out of the sliding sleeve 13. The sliding rod 14 will drive the fixing rod 22 to move, and the fixing rod 22 will pull the tarpaulin 4 out. When the sliding rod 14 is pulled to the tail, the position of the sliding rod 14 is locked and fixed by the locking assembly. At this time, the tarpaulin 4 can shield the heat dissipation port from rain, preventing rainwater from entering the box body 2 from the heat dissipation port and affecting the generator set, thereby improving the rainproof effect of the generator set.

[0024] In the present utility model, the connecting assembly includes two cavities 17, both of which are opened in the fixed block 5, and a rotating rod 20 is rotatably connected in the fixed block 5. Both ends of the rotating rod 20 extend into the cavity 17 and are keyed to the second bevel gear 21. One end of the threaded rod 19 passes through the fixed block 5 and extends into the cavity 17 and is keyed to the first bevel gear 18, and the first bevel gear 18 is meshed with the second bevel gear 21. When one of the threaded rods 19 is rotated, one of the threaded rods 19 will drive the first bevel gear 18 to rotate, and the first bevel gear 18 will drive the second bevel gear 21 to rotate, and the second bevel gear 21 will drive the rotating rod 20 to rotate. The rotating rod 20 drives the other threaded rod 19 to rotate through the meshing between the second bevel gear 21 at the other end and the first bevel gear 18, so that the two threaded rods 19 rotate synchronously, thereby ensuring that the two sliding sleeves 13 rotate synchronously;

[0025] The locking assembly includes a screw 16. A socket is provided on one side of the sliding sleeve 13, and a screw 16 is inserted into the socket. Two threaded holes 15 are provided on one side of the sliding rod 14. The screw 16 is threadedly connected to the threaded hole 15. The screw 16 is removed from the threaded hole 15, and then the sliding rod 14 can be pulled out of the sliding sleeve 13. After the sliding rod 14 is pulled to the tail, the screw 16 is passed through the socket on the sliding sleeve 13 and connected to the threaded hole 15 on the sliding rod 14, so as to lock and fix the sliding rod 14. Two torsion springs 11 are sleeved on the outside of the winding shaft 12, and the two ends of the torsion spring 11 are respectively fixed to the winding shaft 12 and the connecting block 10. The fixing rod 22 will cause the winding shaft 12 to rotate when the tarpaulin 4 is pulled out. The winding shaft 12 will cause the torsion spring 11 to generate torsion. When the slide rod 14 contracts into the sliding sleeve 13, the winding shaft 12 will be reversed by the force of the torsion spring 11 to reel in the tarpaulin 4, thereby realizing automatic reeling of the tarpaulin 4. Electric fans 8 are fixed to the two heat dissipation ports by bolts. The electric fans 8 will extract the hot air inside the box 2 and discharge the hot air in the box 2 through the heat dissipation ports, thereby speeding up the discharge rate of the hot air inside the box 2 and speeding up the air circulation inside the box 2. Protective nets 7 for protecting the electric fans 8 are fixed to the two heat dissipation ports by bolts to prevent the electric fans 8 from being damaged by collision with foreign objects. The bottom outer wall of the box 2 is fixed to the base 1 by bolts.

[0026] Working principle: When it is needed, one of the threaded rods 19 is rotated, and one of the threaded rods 19 will drive the first bevel gear 18 to rotate, and the first bevel gear 18 will drive the second bevel gear 21 to rotate, and the second bevel gear 21 will drive the rotating rod 20 to rotate. The rotating rod 20 will drive the other threaded rod 19 to rotate through the engagement between the second bevel gear 21 at the other end and the first bevel gear 18, so that the two threaded rods 19 rotate synchronously. During the rotation process, the two threaded rods 19 will engage with the threaded sleeve 23 to move the threaded sleeve 23 upward. During the movement process, the threaded sleeve 23 will push the sliding sleeve 13 to rotate through the connecting rod 9, and the connecting rod 9 will engage with the first bevel gear 18. The threaded sleeve 23 and the sliding sleeve 13 rotate. When the sliding sleeve 13 rotates to a suitable angle, the threaded rod 19 is stopped from rotating, and the screw 16 is removed from the threaded hole 15. Then the sliding rod 14 can be pulled toward the outside of the sliding sleeve 13. The sliding rod 14 will drive the fixing rod 22 to move, and the fixing rod 22 will pull out the tarpaulin 4. When the sliding rod 14 is pulled to the tail, the screw 16 is passed through the jack on the sliding sleeve 13 and connected with the threaded hole 15 on the sliding rod 14, so as to lock and fix the sliding rod 14. At this time, the tarpaulin 4 can shield the heat dissipation port from rain, preventing rainwater from entering the box body 2 from the heat dissipation port and affecting the generator set, thereby improving the rainproof effect of the generator set.

[0027] Furthermore, the terms "installed," "disposed," "connected," and "socketed" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
