Drawings
The present invention is further explained by using the attached drawings, but the content in the attached drawings does not constitute any limitation to the present invention.
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic structural diagram of the handcart.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Example 1
Fig. 1 shows a handcart type switch cabinet, which comprises a switch cabinet body 1, a handcart 2, a static contact 3, a moving contact 4, an avoiding groove part 41, a threaded groove hole 5, a limiting ring groove 6, a temperature sensor 7, a limiting block 8, a clamping groove 9, a transverse groove 10, a spring 11 and a clamping block 12.
The avoiding groove part 41 is formed by the outer side surface of the movable contact 4 in a concave mode, a thread groove hole 5 is formed in the avoiding groove part 41, and a limiting ring groove 6 is formed at the bottom of the thread groove hole 5; the diameter of the limiting ring groove 6 is smaller than that of the threaded groove hole 5; a plurality of elastic clamping structures are installed on the side wall of the limiting ring groove 6 along the circumferential direction, the thread groove hole 5 is in threaded connection with a temperature sensor 7, a limiting block 8 matched with the limiting ring groove 6 is formed at the bottom of the temperature sensor 7 in a protruding mode, and a clamping groove 9 matched with the elastic clamping structures is formed in the side wall of the limiting block 8. The elastic clamping structure comprises a transverse groove 10 which is concavely formed on the side wall of the limiting ring groove 6, and the bottom of the transverse groove 10 is connected with a clamping block 12 through a spring 11. The outer end of the latch 12 is spherical or conical. The temperature sensor 7 is a wireless temperature sensor.
By mounting the temperature sensor 7 on the movable contact 4 in this manner, the temperature sensor 7 can be replaced and detected when the car is pulled out. In order to prevent the temperature sensor 7 from being knocked down when the hand truck enters and exits, the escape groove portion 41 is provided to prevent the hand truck from being collided. And in order to prevent the temperature sensor 7 from falling off gradually caused by vibration and the like, a limiting ring groove 6 and an elastic clamping structure are arranged. Therefore, the temperature sensor 7 is connected to the threaded groove hole 5 in a threaded manner, the limiting block 8 is pressed downwards, and then the clamping block 12 is clamped into the limiting ring groove 6 under the pushing of the spring. Thus, when the temperature sensor 7 is vibrated and tends to fall off in an upward rotating manner, the temperature sensor is blocked by the fixture block 12, so that the temperature sensor is prevented from falling off in a vibrating manner.
Example 2
On the basis of embodiment 1, in order to prevent the handcart from being pushed out of place due to single-sensor false alarm, the following settings are carried out:
the front end and the rear end of the handcart 2 are respectively fixed with an induction convex block 13, the middle part of the handcart 2 is fixed with a pushing block 14, the front end and the rear end inside the handcart cavity of the switch cabinet body 1 are arranged on a proximity switch matched with the induction convex block 13, and the middle part is provided with a self-resetting microswitch matched with the pushing block 14. The push block 14 and the two sensing lugs 13 are all at different levels. The sensing bumps 13 are tapered.
Therefore, the handcart senses the corresponding sensing bumps 13 through the proximity switches at the front end and the rear end, and the pushing block 14 is pushed to be in place when touching the self-resetting microswitch. When only one sensor senses a signal, the corresponding alarm device on the switch cabinet body gives an alarm (an alarm lamp), if the sensor fails, the pushing is stopped, and all the sensors are checked. When the three sensors simultaneously sense signals, the pushing is in place, and the sensors have no fault.
Because three position detection devices are arranged and two different sensors are arranged, the problem that a single sensor is easily interfered by the outside world and misjudged is effectively solved.
It should be finally noted that the above embodiments are only used for illustrating the technical solutions of the present invention, not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equally without departing from the spirit and scope of the technical solutions of the present invention.
