The technical scheme is as follows:
the utility model provides an explosion-proof machine shell structure, its includes the casing, be equipped with the louvre on the rear end cap of casing, its characterized in that: the central position of the rear end cover is provided with a rotating shaft section, the rotating shaft section is sleeved with a baffle, the baffles are linked, the appearances of the baffles are matched with those of the heat dissipation holes, the end part of one of the baffles is provided with a flange, the flange is movably connected with the end part of a connecting rod of the electric push rod, and a rod seat of the electric push rod is movably connected with the rear end cover;
it is further characterized in that: the baffle is fan-shaped;
the rear end cover is provided with a first stop block and a second stop block, the fan-shaped baffle rotates between the first stop block and the second stop block to open and close the heat dissipation holes, and protective pads are respectively arranged on the first stop block and the second stop block at positions in contact with fan blades of the fan-shaped baffle;
the flange is connected with the end part of the connecting rod through a first rotating shaft, the rear end cover is provided with a connecting block, and the connecting block is connected with the rod seat of the electric push rod through a second rotating shaft;
the rear end cover is provided with a rolling bearing matched with the rotating shaft section, and the sector baffle is sleeved on the rotating shaft section through the rolling bearing;
the casing is made of aluminum alloy materials.
After the structure is adopted, in rainy and snowy weather, the electric push rod arranged on the rear end cover is started, the electric push rod contracts and simultaneously pulls the fan-shaped baffle to rotate, when the fan-shaped baffle contacts the second stop block, the electric push rod stops contracting, and at the moment, the fan-shaped baffle covers the heat dissipation holes in the rear end cover, so that external water can be prevented from entering the motor from the heat dissipation holes; when the weather changes fine, the electric putter on the rear end cap is restarted, and electric putter extends, and pulling sector baffle rotates simultaneously, and electric putter stops extending when sector baffle contacts first dog, and the louvre on the rear end cap is opened to sector baffle this moment, so make explosion proof machine outside water can not follow the louvre infiltration inside when sleet weather, cause explosion proof machine internal circuit short circuit, ensure that explosion proof machine uses.

fig. 2 is a front view of the rear end cap of the present invention;
fig. 3 is an enlarged schematic view of a portion a in fig. 2 according to the present invention.
In the figure: 1. a housing; 2. a motor shaft; 3. a rear end cap; 4. a front end cover; 5. an explosion-proof fiber layer; 6. a flame retardant layer; 7. a rotating shaft section; 8. a rolling bearing; 9. a fan-shaped baffle plate; 10. heat dissipation holes; 11. a flange; 12. a connecting rod; 13. an electric push rod; 14. a first rotating shaft; 15. a second rotating shaft; 16. connecting blocks; 17. a first stopper; 18. a second stop.
Detailed Description
As shown in fig. 1 to 3, an explosion-proof motor housing structure includes a housing 1, an explosion-proof fiber layer 5 is disposed on an inner wall of the housing 1, a flame retardant layer 6 is disposed on an inner wall of the explosion-proof fiber layer 5, and a heat dissipation hole 10 is disposed on a rear end cover 3. The base 1 is made of aluminum alloy materials, and can prevent rusting under the influence of rain, snow and weather.
Fixed rotating shaft section 7 that is equipped with in the 3 central point of rear end cap puts, be equipped with on the rear end cap 3 with rotating shaft section 7 complex antifriction bearing 8, fan-shaped baffle 9 overlaps through antifriction bearing 8 and establishes on rotating shaft section 7, be equipped with flange 11 on one of them flabellum tip of fan-shaped baffle 9, flange 11 is through the connecting rod 12 tip on the 14 swing joint electric putter 13 of first pivot, the end fixing who keeps away from fan-shaped baffle 9 on the rear end cap 3 is equipped with a connecting block 16, electric putter 13's rod socket passes through second pivot 15 and connecting block 16 swing joint, electric putter 13 control connecting rod 12 contracts and extends, thereby drive fan-shaped baffle 9 and rotate.
The rear end cover 3 is provided with a first stop block 17 and a second stop block 18, the first stop block 17 and the second stop block 18 are arranged to enable the fan-shaped stop plate 9 to rotate in a reciprocating mode within a fixed angle for opening and closing the heat dissipation holes 10, and the first stop block 17 and the second stop block 18 are respectively provided with a protection pad at the contact position with fan blades of the fan-shaped stop plate 9.
The working principle of the utility model is as follows:
in rainy and snowy weather, the electric push rod 13 is started, the electric push rod 13 contracts to drive the fan-shaped baffle 9 to rotate, the fan-shaped baffle 9 stops rotating when contacting the second stop dog 18, and at the moment, the fan-shaped baffle 9 closes the heat dissipation holes in the rear end cover 3, so that water is prevented from entering the explosion-proof motor; when the weather turns fine, the electric push rod 13 is started, the electric push rod 13 extends to drive the fan-shaped baffle 9 to rotate, the fan-shaped baffle 9 stops rotating when contacting the first stop dog 17, and at the moment, the fan-shaped baffle 9 opens the heat dissipation holes in the rear end cover 3. So make explosion-proof machine select to open or close the louvre 10 on the rear end cover 3 at different weather, outside water from louvre 10 infiltration is inside when preventing during sleet weather, causes explosion-proof machine internal circuit short circuit, ensures that explosion-proof machine uses.
