Mining diesel generator set

[0020] The present invention will be described in detail below in conjunction with the drawings and specific embodiments:

[0021] Such as figure 1 , figure 2 , image 3 with Figure 4 The mine diesel generator set shown includes a support base 1 on which a generator set 2 is installed. The support base 1 is fitted with a silent box cover 3 covering the entire engine block 2, thereby protecting the engine Group 2 is not polluted by external particles and dust, and it also reduces the noise generated by the engine block 2 when it is working. The bottom side of the support base 1 is welded with several lifting hooks 7 for installing the silent box cover 3, the silent box The bottom end of the cover 3 is clamped on the hoisting hook 7 so as to fit on the support base 1. The support base 1 is also provided with a support 9 for supporting the silent box cover 3, so that the silent box cover 3 is more stably installed on the support On the base 1, an air inlet and dustproof net cover 31 is also provided at the air inlet on the side of the silent box cover 3. The air inlet and dustproof net cover 31 is arranged inside the silent box cover 3, effectively avoiding external dust With the air inlet entering the inside of the silent box cover 3; the engine block 2 has an air intake pipe 4, and the air intake pipe 4 is connected with a primary air filter 51 and a secondary air filter 52 with a double filter element. The first-stage filter 52 is located inside the silent box cover 3 and connected to the intake pipe 4, and the primary filter 51 is located outside the upper end of the silent box cover 3 and is connected to the secondary filter 52 through a hard pipe 53 passing through the silent box cover 3; The generator set 2 also has a smoke exhaust pipe 6. The smoke exhaust pipe 6 is connected with a muffler 61 through a flange 62. The smoke exhaust pipe 6 is located inside the silent box cover 3, and the muffler 61 is located outside the upper end of the silent box cover 3. , And the tail end of the muffler 61 does not exceed the end surface of the silent box cover 3.

[0022] The dust-proof effect of the diesel engine group is increased by the silent box cover 3 and the air inlet dust-proof net cover 31 at the air inlet, and the primary air filter 51 and the secondary air filter on the intake pipe 4 are very good. The device 52 firstly filters the air outside the silent box cover 3, and then filters the air inside the silent box cover 3 twice, which increases the service life of the unit. There are two additional pads under the support base 1. The stable backing plate 8 of the generator set 2 is convenient to use in the mining site.

[0023] It should be emphasized that the above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are all It still falls within the scope of the technical solution of the present invention.
