Abstract
The utility model relates to a heat insulating device of a variable-frequency power generator set. The variable-frequency power generator set comprises a cylinder head and a muffler. The heat insulating device comprises a fastening piece, a heat insulating plate, a lower air guide plate which is arranged between the heat insulating plate and the cylinder head, a bush and a flat pad, wherein the heat insulating plate and the lower air guide plate are fixedly arranged on the cylinder head through the bush and the flat pad; the heat insulating plate is arranged between the cylinder head and the muffler; and the heat insulating plate and the lower air guide plate share the fastening piece and are fixedly connected with the muffler. The heat insulating device of the variable-frequency power generator set has the beneficial effects that since the heat insulating plate is arranged between the cylinder head and the muffler, the heat of the muffler is prevented from being transferred to the cylinder head in a heat transfer way of hot air convection, and the cylinder head is guaranteed to work in a normal working environment.
Description
Technical field
The utility model relates to a kind of variable-frequency power generation unit, relates in particular to the heat-proof device of this variable-frequency power generation unit.
Background technique
The heat radiation of motor directly affects variable-frequency power generation unit performance, reliability and working life.
Chinese patent ZL201020565523.8 discloses a kind of digital frequency conversion generator group.This patent is in order to make compact, the reduced volume of set structure, with the silencing apparatus layout below engine cylinder cap.Effectively utilized the idle space of generator set.But this patent has following drawback: the first since with the silencing apparatus layout below engine cylinder cap, the heat that silencing apparatus produces is delivered to cylinder head with thermal-radiating thermaltransmission mode with its heat; The second since with the silencing apparatus layout below engine cylinder cap, hot air is delivered to cylinder head with the thermaltransmission mode of convection current with heat.Thus, cause Cylinder Head Temperature too high, make the valve oil seal in the cylinder, deformation failure behind the high temperature; Cause in the firing chamber high temperature and high pressure gas to scurry into cylinder head, form cylinder head machine oil carbon distribution; The distribution device part shortens working life greatly; Because the valve oil seal distortion causes Abnormal Engine Valve Sound.
Summary of the invention
The utility model technical issues that need to address have provided a kind of heat-proof device of variable-frequency power generation unit, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The heat-proof device of variable-frequency power generation unit of the present utility model, described variable-frequency power generation unit comprises: cylinder head and silencing apparatus; Described heat-proof device comprises: fastening piece, thermal baffle, the lower wind deflector, the mistake that are placed between thermal baffle and the cylinder head are overlapped and plain cushion; Described thermal baffle and lower wind deflector are fixed on cylinder head by crossing cover and plain cushion; Described thermal baffle is between cylinder head and silencing apparatus; Described thermal baffle and lower wind deflector share fastening piece and silencing apparatus is fixed.
Compared with prior art, the beneficial effects of the utility model are: A, since thermal baffle between cylinder head and silencing apparatus, effectively avoided the thermaltransmission mode of hot air with convection current, the silencing apparatus heat has been delivered to cylinder head, guaranteed that cylinder head working under normal working environment.
B, because the thermal baffle surface-brightening, effectively avoided heat that silencing apparatus produces with thermal-radiating thermaltransmission mode, its heat is delivered on the motor, cause the phenomenon of engine overheat.
C, employing thermal baffle and lower wind deflector are fixed on the cylinder head by crossing cover, so just make enough spaces are arranged between thermal baffle and the cylinder head, guarantee that thermal baffle does not directly contact cylinder head, effectively avoid heat with heat conducting thermaltransmission mode, its heat is delivered on the motor.
D, employing thermal baffle and lower wind deflector share fastening piece and install, and make set structure compacter, reduce cost, weight saving.

By Fig. 1, Fig. 2, Fig. 3 as seen: the heat-proof device of variable-frequency power generation unit of the present utility model, described variable-frequency power generation unit comprises: cylinder head 6 and silencing apparatus 7; Described heat-proof device comprises: fastening piece 1, thermal baffle 2, be placed in lower wind deflector 5 between thermal baffle 2 and the cylinder head 6, cross and overlap 4 and plain cushion 3; Described thermal baffle 2 and lower wind deflector 5 by cross overlap 4 and plain cushion 3 be fixed on cylinder head 6; Described thermal baffle 2 is between cylinder head 6 and silencing apparatus 7; Described thermal baffle 2 shares fastening piece 1 with lower wind deflector 5 and fixes with silencing apparatus 7.
Described thermal baffle 2 smooth surfaces, L-shaped structure.
Described lower wind deflector 5 adopts steel plate punched to form; Described mistake is overlapped 4 usefulness metal tubes and is made.
Adopt in the utility model thermal baffle 2 and lower wind deflector 5 by cross overlap 4 and plain cushion 3 be fixed on the cylinder head 6, cross and overlap 4 usefulness metal tubes and make; So just making between thermal baffle 2 and the cylinder head 6 has enough spaces, guarantees that thermal baffle 2 does not directly contact cylinder head 6, effectively avoids heat with heat conducting thermaltransmission mode, and its heat is delivered on the motor.
The material of the good heat dissipation effect such as thermal baffle 2 employing aluminum alloys is made surface-brightening.L-shaped structure is provided with mounting hole in the cylinder head relevant position.
Because thermal baffle 2 surface-brightenings have effectively avoided the heat of silencing apparatus 7 generations with thermal-radiating thermaltransmission mode, and its heat is delivered on the motor, cause the phenomenon of engine overheat.
Adopt thermal baffle 2 to share fastening piece 1 with lower wind deflector 5 and install, make set structure compacter, reduce cost, weight saving.
