Background technology
Motor has important effect in existing industrial production.Motor provides power as drive unit for various kinds of equipment, and can motor operate as normal directly influence work such as the research and development, production, check of product.As shown in Figure 3, in the prior art, the electric wire of motor generally all feeds motor internal by the cable conduct parcel.In motor is used for the low temperature environment cabin when (temperature is below zero degrees celsius), low temperature environment in the cable conduct connection cabin and hot environment out of my cabin, and with Cryogenic air in the cabin and high temperature air conducting out of my cabin, under the bigger situation of the humidity of air, high temperature air is run into Cryogenic air and is just produced condensed water, so just can form condensed water on cable conduct inside and electric wire.Condensed water flows into motor internal along cable conduct and the electric wire terminal box of flowing through, and causes motor internal ponding, damages motor.
The utility model content
The utility model aims to provide a kind of water-tight device that can make motor operate as normal under the low temperature environment cabin, and this water-tight device can prevent that condensed water from entering motor in cable conduct, and it is simple in structure, reliable operation.
A kind of motor water-tight device, described motor is for comprising terminal box, the motor of electric wire and cable conduct, described motor water-tight device comprises seal cover, baffle, Cancellation Missed and tube connector, described seal cover and Cancellation Missed are installed on the both ends of baffle respectively, the sidewall of described baffle also has a through hole, described tube connector one end is connected in this through hole, and connect with described baffle inner chamber, the tube connector other end is connected with the terminal box of motor, described cable conduct is communicated with baffle by seal cover, and the electric wire Self-sealed lid is drawn through the tube connector inner chamber and inserted in the connection box for motor.
The motor of this water-tight device is housed, and the condensed water that forms in the cable conduct when working in low temperature environment can flow out to motor outside along this water-tight device, thereby the work that motor can safety and stability and can not be subjected to the influence of condensed water.
Description of drawings
Be described in further details below in conjunction with accompanying drawing and embodiments of the present invention:
Fig. 1 is the structural representation of a kind of motor water-tight device of the present utility model;
Fig. 2 is the design of part schematic diagram of a kind of motor water-tight device of the present utility model;
Fig. 3 is a motor wiring schematic diagram of the prior art.
Embodiment
As depicted in figs. 1 and 2, a kind of motor water-tight device, described motor section branch comprises terminal box 9, electric wire 3, cable conduct 1 and motor 10.Described motor water-tight device also comprises seal cover 2, baffle 4, Cancellation Missed 5 and tube connector 7.Baffle 4 two ends have internal thread, and the internal thread of its middle and upper part is connected with the external screw thread of seal cover 2, and the internal thread of bottom is connected with the external screw thread of Cancellation Missed 5; The middle part of baffle 4 also has an internal thread hole, utilizes threaded block 6 to be connected with tube connector 7 by this screwed hole.Described seal cover 1 is circular, has a manhole on it, and its internal diameter is more smaller so that cable conduct is clamped in this manhole than the external diameter of cable conduct 1.This through hole can also be for triangle, square etc., as long as can match chucking with the shape of cable conduct.Seal cover 1 link has external screw thread and water conservancy diversion cavity 4 upper end screw-internal thread fit.Described Cancellation Missed 5 is circular, and its link has external screw thread and water conservancy diversion cavity 4 lower end screw-internal thread fit, and Cancellation Missed 5 has a through hole, and this through hole extends downwards, forms a tubule portion, can be used for thorough draining.This tubule portion thoroughly exports to the motor outside with condensed water and can not stick on the outer surface of baffle.All there is external screw thread at described tube connector 7 two ends, the one end is connected with baffle middle part internal thread hole by threaded block 6, the surfaces externally and internally of threaded block 6 all has screw thread, the screw-internal thread fit of outer surface thread and baffle 4 areoles wherein, the inner surface screw thread cooperates with the external screw thread of tube connector 7 one ends, and therefore the inner chamber of baffle is communicated with the inner chamber of tube connector; The other end of tube connector 7 is connected with connection box for motor 9 by screwed flange 8, screwed flange 8 has internal thread and cooperates with the external screw thread of tube connector 7 these ends, screwed flange 8 be fixed by bolts on the connection box for motor 9 and whereby good seal be preset in the hole that supply lines on the terminal box 9 inserts.Electric wire approximately forms the angle of 90 degree when baffle redirect to tube connector.Below respectively be threaded and not only play interconnect function but also seal.
Please refer to shown in Figure 1, the working condition of this motor water-tight device is, cable conduct 1 passes seal cover 2 and a bit of protruding in the baffle inner chamber is arranged, because the external diameter of cable conduct 1 is bigger than the diameter of the aperture of seal cover 2, so being clamped in this aperture, can not become flexible easily by cable conduct 1, electric wire 3 stretches out from cable conduct 1, axis direction along baffle is downward, when arriving tube connector 7 position height, be folded in the tube connector 7, in tube connector 7 enters into connection box for motor 9 with 90 degree angles roughly.Condensed water in the cable conduct 1 mainly sticks on the inwall of cable conduct 1, and small part is attached on the electric wire 3.Condensed water along cable conduct 1 inwall will drop to when flowing to the port of cable conduct 1 on the Cancellation Missed 5, can flow out to motor 10 outsides along the aperture on the Cancellation Missed 5 then.Condensed water along electric wire 3 can drop to downwards on the Cancellation Missed 5 at electric wire 3 corners disengaging electric wire 3, and the aperture on Cancellation Missed 5 flows out to motor 10 outsides.Because the aperture lower end of Cancellation Missed 5 is one section tubule portion, so the condensed water that falls down is bound to flow out to motor 10 outsides completely along this tubule, and can not stick on the outer surface of motor 10, can not stick on the outer surface of baffle 4 self yet.Therefore, there is no fear of entering in the connection box for motor 9 and damage motor 10 along the condensed water of cable conduct 1 and electric wire.Guaranteed the work safety, stable and reliable of motor.
The foregoing description only is for the present invention will be described, rather than limitation of the present invention, those skilled in the art will appreciate that without departing from the inventive concept of the premise, and the utility model also has many modification.
