Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the technical solution provided by the present invention is: a distribution box for preventing overheating protection and early warning comprises a box body 1; the top fixedly connected with warning light 2 of box 1, the first wire 3 of bottom fixedly connected with and the second wire 4 of warning light 2, the bottom fixedly connected with battery 5 of box 1, the one end of warning light 2 and the anodal electric connection of battery 5 are kept away from to second wire 4, the negative pole electric connection of battery 5 has third wire 6, the fixed pipe 7 of bottom fixedly connected with of box 1, sliding connection has piston 8 in the fixed pipe 7, piston 8's last fixed surface is connected with L shape pole 9, the cover is equipped with connecting block 10 on the third wire 6, connecting block 10 is made for conducting material, the one end terminal surface that piston 8 was kept away from to L shape pole 9 offsets with the lower surface of connecting block 10.

Thus, by filling mercury in the fixed tube 7, when the temperature of the electrical component in the box body 1 is too high for a long time, according to the principle of expansion with heat and contraction with cold of mercury, the mercury in the fixed tube 7 will expand, thereby pushing the piston 8 to move upwards, when the piston 8 moves upwards, the L-shaped rod 9 fixedly connected to the upper surface of the piston 8 will move upwards along with it, because the end surface of the L-shaped rod 9 far away from the piston 8 is abutted against the lower surface of the connecting block 10, so that the L-shaped rod 9 can push the connecting block 10 to move upwards along the outer surface of the third wire 6, so that the top end of the connecting block 10 is sleeved on the first wire 3, because the connecting block 10 is made of a conductive material, the connecting block 10 can connect the first wire 3 with the third wire 6, so that a series circuit is formed between the storage battery 5 and the warning light 2, thereby the warning light 2 plays a warning role for external workers, the worker is reminded that the temperature of the electric inside the case 1 is too high so that the worker can handle it.

Referring to fig. 4, the outer surface of the connecting block 10 close to one side of the L-shaped rod 9 is uniformly and fixedly connected with a plurality of latches 11, and the connecting block 10 is close to or far from the first wire 3 by changing the positions of the inclined blocks 13 at different latches 11, so as to adjust the set value of the box body 1 required temperature; one end of the first conducting wire 3 close to the third conducting wire 6 is fixedly connected with an electromagnet 16, the electromagnet 16 is electrically connected with the first conducting wire 3, and the model of the electromagnet 16 is JL-0837.

So, through being promoted upwards when connecting block 10, when putting through the circuit between battery 5 and the warning light 2, electro-magnet 16 is also put through, make electro-magnet 16 adsorb connecting block 10, avoid because the temperature in the box 1 reduces, the mercury shrink in the fixed pipe 7 leads to the circuit disconnection, through being in the on-state with the circuit always, make the workman must open box 1 and just can the break circuit, thereby make the workman can examine the electric elements in the box 1, prevent the incident because of electric elements takes place to burn out and leads to.

Referring to fig. 4, a through hole is formed in an end surface of the L-shaped rod 9 close to the connecting block 10, a moving rod 12 is inserted into the through hole, the moving rod 12 is slidably connected to an inner wall of the through hole, an inclined block 13 is fixedly connected to one end of the moving rod 12 close to the connecting block 10, the inclined block 13 abuts against a lower surface of the latch 11, a spring 14 is fixedly connected to the other end of the moving rod 12, and one end of the spring 14, far away from the moving rod 12, abuts against the inner wall of the L-shaped rod 9.

So, when the temperature in the box 1 reduces, the mercury shrink back in the fixed pipe 7, piston 8 will drive L shape pole 9 and descend, because the lower surface of sloping block 13 is the inclined plane setting for latch 11 can promote sloping block 13 to the inside of L shape pole 9, thereby makes L shape pole 9 can the downstream, can not drive connecting block 10 downstream.

Referring to fig. 3, the first wire 3 and the third wire 6 are disposed in a conductive metal rod structure, a distance between the first wire 3 and the third wire 6 is less than a length of the connection block 10, and the first wire 3 and the third wire 6 are located on the same straight line.

So, on promoting first wire 3 from third wire 6 through with connecting block 10 to the switch-on circuit makes warning light 2 remind the external world, sets up the distance between first size and the third size into the length that is less than connecting block 10, can avoid connecting block 10 to take place to drop.

Referring to fig. 3, mercury is filled in the fixed tube 7 below the piston 8.

Thus, the temperature change in the case 1 is monitored by the principle of expansion with heat and contraction with cold of mercury.

Referring to fig. 4, the upper surface of the inclined block 13 is a plane, the lower surface of the inclined block 13 is an inclined structure, and the outer surface of the inclined block 13 is fixedly connected with a push rod 15.

Therefore, the upper surface of the inclined block 13 is set to be a plane which can push the latch 11 to move upwards, and the lower surface of the inclined block 13 is set to be an inclined surface, so that the L-shaped rod 9 can move downwards; by pulling the push rod 15, the inclined block 13 is moved towards the L-shaped rod 9, and the connecting block 10 can be pushed to move downwards, so that the circuit is disconnected.
