Embodiment Construction
[0013] The present invention is specifically described below in conjunction with accompanying drawing, as figure 1 As shown in the structural diagram of the bolt-type quick-change explosion-proof plug, the outlet pipe 4 is welded to the bottom of the machine base. The side plate is welded. When welding, the outer end of the drain pipe should be inclined downward by 5-10 degrees, so as to facilitate the outflow of accumulated water in the cavity and the outside water entering the cavity through the drain pipe; the quick-change explosion-proof plug is a bolt-type quick-change Explosion-proof plugs, such as image 3 As shown, the bolt-type quick-change explosion-proof plug is a screw 6, and the front end of the screw is an explosion-proof thread, and the thread is more than 6 buttons. The explosion-proof requirements should meet the requirements of GB3636.2, that is, the accuracy of the thread surface Not less than 6H / 6g, and the average surface roughness Ra of the bonding surfa...

The invention discloses a structure for releasing accumulated water in a motor chamber. The structure comprises a water releasing pipe that is fixed at a bottom of a base; one end of the water releasing pipe is communicated with the inner chamber of the base; and the other end of the water releasing pipe is provided with a quick-change explosion-proof end cap. A lower pitching angle between the water releasing pipe and a horizontal plane is 5 to 10 degrees; and flame-proof screw threads are arranged on the water releasing pipe and the quick-change explosion-proof end cap. According to the invention, advantages of the structure are as follows: damage on a winding due to flooding water in a motor chamber can be prevented; and thus service life of the motor can be prolonged. Moreover, costs are low; the structure is simple; the effect is good; and an explosion-proof performance of the motor is not influenced.
Description
technical field [0001] The invention relates to the field of electromechanical equipment, in particular to a structure for releasing accumulated water in a motor cavity. Background technique [0002] When the motor is underground, water may enter the cavity, which has a great impact on the insulation of the motor, and even burns the windings, so that the supporting mining equipment cannot operate normally. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a structure for releasing the accumulated water in the cavity of the motor. The specific plan is as follows; [0004] A structure for releasing accumulated water in a motor chamber, comprising a water discharge pipe fixed at the bottom of the machine base, one end of the water discharge pipe communicates with the inner cavity of the machine base, and the other end is provided with a quick-change explosion-proof plug; the water discharge...
