Abstract
The utility model discloses a radiation device for a cutterhead frequency conversion cabinet of a shield tunneling machine which belongs to the cutterhead frequency conversion cabinet of a shield tunneling machine field. The cutterhead frequency conversion cabinet of the shield tunneling machine comprises a frequency conversion cabinet and an air cooling frequency converter internally fixed on the mounting baseplate of the frequency conversion cabinet. A cool air inlet is positioned on the frequency conversion cabinet; a filter screen is positioned on the cool air inlet; the cool air inlet is communicated with the lower part of the air cooling frequency converter through a tapered connector and a separated air duct; a hot air outlet is positioned on the frequency conversion cabinet; a filter screen is positioned on the hot air outlet; and the hot air outlet is communicated with the upper part of the air cooling frequency converter through the tapered connector and the separated air duct. The radiation device for the cutterhead frequency conversion cabinet of the shield tunneling machine has advantages of simple structure, stability, high efficiency, and low cost.
Description
Technical field
The utility model belongs to cutter head of shield machine frequency conversion tank field.
Background technology
Because being subjected to the restriction of shield machine bad working environments, require the cutterhead frequency conversion tank must reach the degree of protection of IP55.Yet under so high degree of protection, heat dissipation problem just becomes the primary factor that influences frequency converter stable operation.The radiating mode of cutter head of shield machine frequency conversion tank mainly contains following two kinds at present, and a kind of is the air cooling mode that adopts common shared air channel, and another is the water-cooling pattern that adopts external water circulation cooling frequency converter.Though the former structure is simple relatively, but the cheap relatively radiating effect of cost is relatively poor, although latter's radiating effect obviously but because of its complex structure, the fault point is many, reliability is low so maintaining is loaded down with trivial details, and has with high costsly almost turned over one times with respect to the former its cost.
The utility model content
The purpose of this utility model is: propose a kind of simple, reliable, efficient, the cutter head of shield machine frequency conversion tank heat abstractor that cost is low.
The purpose of this utility model realizes by following technical proposals:
A kind of cutter head of shield machine frequency conversion tank heat abstractor, comprise frequency conversion tank, with and in be fixed in the air-cooled variable-frequency device of installing on the base plate, offer cool air inlet on the described frequency conversion tank, which is provided with screen pack, and run through described installation base plate by reducing interface and independent ventiduct and be communicated with described air-cooled variable-frequency device bottom, also offer hot air outlet on the described frequency conversion tank, which is provided with screen pack, and run through described installation base plate by reducing interface and independent ventiduct and be communicated with described air-cooled variable-frequency device top.
As optimal way, described reducing interface is that frequency conversion tank is to base plate direction convergent is installed.
Workflow of the present utility model: the cold air outside the cabinet is through cool air inlet and screen pack and reducing interface on the frequency conversion tank, enter in the independent ventiduct cavity that is connected with the frequency converter bottom, the fan that passes through frequency converter self cools off frequency converter IGBT power cell and control board with cold air inspiration frequency converter inside again.Discharged outside the frequency conversion tank via independent ventiduct and the reducing interface of hot air outlet on the thermovent at rear, frequency converter top and the frequency conversion tank by the hot-air that produces after the heat exchange simultaneously.Thereby realized the cooling to frequency converter.The characteristics of this structure are to adopt airtight independent ventiduct to reduce thermal loss, improved the efficient of heat exchange, have adopted the reducing interface to reduce the speed that passes in and out wind simultaneously, have reduced the adsorption capacity of dust, have guaranteed the cleannes of frequency converter.
The beneficial effects of the utility model: simple, the with low cost but cooling effect highly significant of this system configuration.Be applicable to the cooling of the cutter head of shield machine frequency conversion tank that single motor 200KW is following.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, a kind of cutter head of shield machine frequency conversion tank heat abstractor, comprise frequency conversion tank 1, with and in be fixed in the air-cooled variable-frequency device of installing on the base plate 23, frequency conversion tank 1 bottom offers cool air inlet 4, which is provided with screen pack 5, and run through by reducing interface 6 and independent ventiduct 7 and base plate 2 to be installed to be communicated with air-cooled variable-frequency device 3 bottoms, frequency conversion tank 1 top also offers hot air outlet 8, which is provided with screen pack 5, and run through by reducing interface 6 and independent ventiduct 7 and base plate 2 to be installed to be communicated with air-cooled variable-frequency device 3 tops.As optimal way, reducing interface 6 is that frequency conversion tank 1 is to base plate 2 direction convergents are installed.
Workflow of the present utility model: cool air inlet 4 and screen pack 5 and the reducing interface 6 of cold air process frequency conversion tank 1 bottom that cabinet is outer, enter in independent ventiduct 7 cavitys that are connected with air-cooled variable-frequency device 3 bottoms, fan by air-cooled variable-frequency device 3 self is cold air inspiration air-cooled variable-frequency device 3 inside again, cooling frequency converter IGBT power cell and control board.Simultaneously by outside the thermovent and frequency conversion tank 1 top hot air outlet 8 and independent ventiduct 7 and reducing interface 6 discharge frequency conversion tank 1 of the hot-air that produces after the heat exchange via rear, air-cooled variable-frequency device 3 top.Thereby realized the cooling to air-cooled variable-frequency device 3.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
Claims (2)
1. cutter head of shield machine frequency conversion tank heat abstractor, comprise frequency conversion tank, with and in be fixed in the air-cooled variable-frequency device of installing on the base plate, it is characterized in that: offer cool air inlet on the described frequency conversion tank, which is provided with screen pack, and run through described installation base plate by reducing interface and independent ventiduct and be communicated with described air-cooled variable-frequency device bottom, also offer hot air outlet on the described frequency conversion tank, which is provided with screen pack, and run through described installation base plate by reducing interface and independent ventiduct and be communicated with described air-cooled variable-frequency device top.
