Abstract
An explosion-proof frequency converter having a water cooling structure comprises an explosion-proof shell and an explosion-proof door. A water cooling system is mounted inside the explosion-proof shell. One side of the explosion-proof door is mounted on the explosion-proof shell via door spindles. The explosion-proof door is also connected with the explosion-proof shell via bolts. The explosion-proof door is provided with windows and cover plates used for closing the windows. The cover plates are provided with openings for a water inlet pipe and a water outlet pipe of the water cooling system to pass through. The water inlet pipe and the water outlet pipe are led out of the explosion-proof shell by the openings. The cover plates are mounted on the explosion-proof door by bolts. When the explosion-proof frequency converter needs to be maintained or inspected, work in the interior of the explosion-proof frequency converter can be conducted simply after disassembling the cover plates on the explosion-proof door, disconnecting the water inlet pipe and the water outlet pipe of the water cooling system from the cover plates, and opening the explosion-proof door by pushing the explosion-proof door to rotate around the door spindles. Therefore, the heavy explosion-proof door does not need to be completely disassembled; the time for disassembling and assembling the explosion-proof door is reduced; the maintenance and inspection difficulty is lowered; and the work intensity of maintenance personnel is reduced.
Description
Technical field
The utility model relates to a kind of explosion-proof frequency converter with water-cooling structure.
Background technology
Frequency converter used under mine is very high to its explosion-proof performance requirement, conventionally makes the explosion-proof casing of closed type.As shown in Figure 1, its explosion preventing gate of traditional explosion-proof frequency converter is bolted on explosion-proof main casing, and water-cooling system is placed on explosion-proof casing inside.The water inlet of water-cooling system is guided to explosion-proof casing outside with delivery port pipeline by the perforate on explosion preventing gate (size in hole is identical with pipe diameter, and hole site is corresponding with the position of water inlet and delivery port).Based on explosion-proof requirement, water-cooling system water inlet and delivery port are very near apart from explosion preventing gate, water inlet pipe is directly fixed on explosion preventing gate and is difficult to separate with outlet conduit, the shortcoming of this scheme is, when carrying out frequency converter maintenance or detecting, whole explosion preventing gate need to be disassembled, then water inlet pipe could be separated and carries out maintenance work with explosion preventing gate with outlet conduit, because the door-plate of explosion-proof material is very heavy, bring very large trouble so detect to maintenance.
Utility model content
The utility model object is to overcome prior art defect, and a kind of explosion-proof frequency converter with water-cooling structure is provided, and detects inconvenient problem to solve tradition with explosion-proof frequency converter maintenance.
For achieving the above object, the utility model adopts following scheme:
A kind of explosion-proof frequency converter with water-cooling structure, comprise explosion-proof casing and explosion preventing gate, water-cooling system is arranged in explosion-proof casing, explosion preventing gate one side is arranged on explosion-proof casing by door-hinge, explosion preventing gate is also connected with explosion-proof casing by bolt, and explosion preventing gate is provided with the cover plate of windowing and windowing for sealing this, and cover plate is arranged on explosion preventing gate by bolt, on described cover plate, offer the perforate that supplies water-cooling system water inlet pipe and outlet pipe to pass through, water inlet pipe and outlet pipe are guided to explosion-proof casing outside by perforate.
Described explosion preventing gate offers two and windows, and each upper cover plate that this is windowed that is provided for respectively sealing of windowing offers the perforate of passing through for water inlet pipe on a cover plate, and another cover plate is provided with the perforate of passing through for outlet pipe.
The pipe thickness of described water inlet pipe and outlet pipe is greater than 3mm.
Windowing as rectangle on described explosion preventing gate.
Compared with prior art, the utlity model has following advantage:
The utility model arranges and windows and cover plate on explosion preventing gate, on cover plate, offer the perforate that supplies water-cooling system water inlet pipe and outlet pipe to pass through, water inlet pipe and outlet pipe are guided to explosion-proof casing outside by perforate, need to explosion-proof frequency converter be keeped in repair or be detected time, disassemble the cover plate on explosion preventing gate, then the water inlet pipe of water-cooling system is separated with cover plate with outlet pipe, promote subsequently explosion preventing gate around door-hinge rotating opening explosion preventing gate, explosion-proof frequency converter is carried out to internal work, without disassembling thick and heavy explosion preventing gate completely, the time that has reduced dismounting and explosion preventing gate is installed, and reduce and keeped in repair the difficulty detecting, alleviate maintenance personal's working strength, improve the ease for use of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional explosion-proof frequency converter;
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the schematic diagram of water-cooling system in the utility model.
Embodiment
For clearly demonstrating the technical scheme in the utility model, describe in detail below in conjunction with accompanying drawing.
Fig. 2, Fig. 3 are the structural representation of the explosion-proof frequency converter of the utility model band water-cooling structure, explosion-proof frequency converter comprises explosion-proof casing and explosion preventing gate 3, water-cooling system 5 is arranged in explosion-proof casing, explosion preventing gate one side is arranged on explosion-proof casing by upper door-hinge 11 and lower door-hinge 12, explosion preventing gate 3 can rotate and open around door-hinge 11,12, in addition, explosion preventing gate surrounding is provided with connecting bolt, and explosion preventing gate and frequency converter explosion-proof casing are affixed by bolt.Explosion preventing gate is provided with two and windows 41,42 are also provided with the cover plate 21 of windowing for sealing this, 22, on cover plate 21, offer the perforate of passing through for water-cooling system water inlet pipe, on cover plate 22, offer the perforate of passing through for water-cooling system outlet pipe, water inlet pipe and outlet pipe are guided to explosion-proof casing outside by perforate respectively, and described cover plate is arranged on explosion preventing gate by bolt.
Distinguish when frequency converter maintenance detects, only need pull down the corresponding bolt of cover plate 21,22, water inlet pipe is separated with explosion preventing gate with outlet pipe, then by explosion preventing gate surrounding disassembling bolts, explosion preventing gate rotarily opens around door-hinge, without the whole explosion preventing gate of dismounting, remove the problem that is difficult to install by after the explosion preventing gate dismounting of whole heaviness from.
Further, it is strong that the pipe thickness of explosion-proof frequency converter water-cooling system water inlet pipe and outlet pipe is greater than 3mm anti-pressure ability, and door-plate uplifting window is rectangle, facilitates cover plate setting and location.
Further, water inlet pipe and outlet pipe, as far as possible away from door-hinge, facilitate Water pipe movable and dismounting, guarantee that like this window size can be as far as possible little.
For the explosion-proof frequency converter of setting forth in the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
