Description

Technical Field

[0001] The invention relates to the technical field of diesel generator sets, in particular to a double-layer container-type diesel generator which is convenient for maintenance. Background Art

[0002] Diesel generator sets are widely used as backup power sources in various occasions, such as the communications industry, financial and fiscal departments, hospitals, schools, factory computer rooms, airport transportation industry, large shopping malls and public facilities, large data centers, remote areas with insufficient electricity, etc. Containerized diesel generator sets are a common power generation equipment, which are widely used at home and abroad. Standard containers can be placed outdoors without occupying building area, making containerized generator sets accepted by the majority of users.

[0003] Among them, the Chinese patent with announcement number CN217233643U discloses a container-type diesel generator set, which can be installed and fixed on the box cover through the box body and the positioning frame, and can also be flexibly disassembled, so that it is convenient for the staff to lift the diesel engine and generator in the box body, improving the convenience of installation of the diesel engine and generator. Through the cooperation of the exhaust duct and the exhaust fan, the heat inside the box body can be discharged, ensuring the safety of the diesel engine and the generator. At the same time, the pillar can be used to install the protective cover, so that the protective cover can protect the exhaust duct and prevent external rain or foreign objects from entering the exhaust duct.

[0004] In the above scheme, although the detachable box cover is used to facilitate the disassembly and assembly of the diesel generator, the heat is only dissipated by a fixed fan, and the air flow efficiency in the box is low, which does not achieve a good heat dissipation effect. In addition, the box cover is located above the box, which makes it difficult to disassemble it. To this end, we provide a double-layer container diesel generator that is easy to maintain to solve the above problems. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, 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, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-7 As shown, the present invention provides a technical solution: a double-layer container-type diesel generator that is easy to maintain, including a box structure, a generator body 16, two access ports 5, two air inlet pipes 7, two sliders 29, a drive assembly and a linkage assembly.

[0039] The box structure includes a lower box 1 and an upper box 2 fixedly connected to the lower box 1. The lower box 1 is a cavity for accommodating the generator body 16, and the upper box 2 is a cavity for dissipating heat from the generator body 16. The bottom surface of the lower box 1 is fixedly connected to a base 3, and the base 3 is used to support the lower box 1 so that a space is left between the bottom surface of the lower box 1 and the ground. A rain shield 4 is fixedly connected to the upper box 2, and the rain shield 4 forms a shielding structure above the upper box 2 to block rainwater and dust dripping on the upper box 2.

[0040] Among them, the generator body 16 is installed in the lower box body 1, and an exhaust pipe 18 is installed at the discharge end of the generator body 16. The exhaust pipe 18 penetrates the lower box body 1 and extends to the outside of the lower box body 1, and the high-temperature exhaust gas generated by the generator body 16 is discharged to the outside of the lower box body 1 through the exhaust pipe 18.

[0041] Both sides of the lower box body 1 are fixedly connected with an entry and exit channel 14, and explosion-proof doors 15 are hinged on the two entry and exit channels 14. The entry and exit channels 14 and the explosion-proof doors 15 form a passage for workers to enter and exit the lower box body 1 during daily maintenance. A wire tube 17 is embedded on the lower box body 1, and the connecting wire of the generator body 16 passes through the wire tube 17 and extends to the outside of the lower box body 1.

[0042] Among them, two taking and placing ports 5 are respectively opened on the two sides of the lower box body 1, and shielding plates 6 are provided at the two taking and placing ports 5, and ventilation holes are provided on the shielding plates 6. A lifting component for synchronously lifting and lowering the two shielding plates 6 is provided in the lower box body 1. In the working state, the shielding plates 6 will cover the taking and placing ports 5 and block the taking and placing ports 5, and the shielding plates 6 have ventilation holes, which can enable the air in the lower box body 1 to be exchanged with the external air through the ventilation holes.

[0043] In this embodiment, the lifting assembly includes a first motor 9 installed on the base 3 and a first one-way screw 11 rotatably connected to the lower box body 1.

[0045] Among them, two sealing blocks 13 are fixedly connected to both sides of the inner wall of the lower box body 1, and the two ends of the shielding plate 6 are against the two sealing blocks 13. A sealing groove 44 is opened on the inner bottom wall of the lower box body 1, and the bottom end of the shielding plate 6 is inserted into the sealing groove 44. The sealing block 13 is used to block the fitting part between the shielding plate 6 and the lower box body 1, so as to improve the sealing performance of the shielding plate 6 to the access port 5, and the shielding plate 6 is more stable after being inserted into the sealing groove 44.

[0046] The two air inlet pipes 7 are fixedly connected to the upper surface of the upper box body 2, and the two air inlet pipes 7 are installed with filter screens 8.

[0048] The output shaft of the second motor 20 drives the first bidirectional screw 21 to rotate, so that the cleaning block 23 can move toward each other on the first bidirectional screw 21. At this time, the cleaning block 23 will slide on the first guide rod 22, and at the same time, the cleaning block 23 cleans the filter screen 8 through the bristles.

[0051] When the slider 29 moves laterally in the upper box body 2, the transmission gear 34 will mesh with the rack 33, and the transmission gear 34 will drive the rotating shaft 35 to rotate. At this time, the first hinge block 36 on the rotating shaft 35 will perform a circular motion, and the first hinge block 36 under the circular motion will cause the angle of the hinge rod 37 to change, and then drive the swing rod 41 to perform a small reciprocating rotation in the rotating groove 40 through the second hinge block 38 and the connecting shaft 39, thereby adjusting the blowing angle of the second cooling fan 42.
