Abstract
Description
Technical Field

[0002] With the continuous development of intelligent monitoring technology, the requirements for power supply management of monitoring equipment are also increasing. The current monitoring air switches are generally circuit breaker protection, that is, they perform circuit breaker protection when a short circuit occurs in the circuit. They lack overload protection function and insufficient safety performance. In addition, overload protection generally uses thermally deformed metal as the working workpiece. After overload heating, the metal deforms and produces a position to achieve circuit breaking. However, for circuits that need to be restored immediately, the cooling speed of the metal after heating is slightly slow, which affects the operation. At the same time, the air switch is generally equipped with an arc extinguishing structure, and the fire extinguishing structure will instantly generate a large amount of heat. The traditional structure is closed, and this heat relies on natural dissipation, which will cause thermal decay to the internal electronic components and affect their service life.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0028] Example 1, reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, provides a heat dissipation mechanism, including a conductive component 100, by providing a heat conduction chamber 101, a first elastic member 102 inside the heat conduction chamber 101 and a sliding plate 103 arranged at one end of the first elastic member 102, so as to achieve the function of dissipating the heat generated at the moment of arc extinguishing.
[0029] Specifically, the conduction component 100 includes a heat conduction chamber 101, a first elastic member 102 disposed inside the heat conduction chamber 101, and a sliding plate 103 disposed at one end of the first elastic member 102; the sliding plate 103 drives the first elastic member 102 to compress, so that heat is discharged from the heat conduction chamber 101.
[0030] Preferably, a one-way valve 101a is installed on the side of the heat transfer chamber 101 , and an exhaust hole 101b is provided on the outer wall of the heat transfer chamber 101 , and the exhaust hole 101b is communicated and cooperated with the heat transfer chamber 101 .
[0031] Among them, two heat-conducting chambers 101 are arranged inside the shell 201, and one-way valves 101a are installed on the sides of the heat-conducting chambers 101.

[0032] In summary, when the arc extinguishing metal sheet group 202a introduces an arc and generates a large amount of heat at the moment of power failure, the internal air expands due to the heat and is discharged into the interior of the two heat transfer chambers 101 through the two one-way valves 101a, and pushes the sliding plate 103 to compress the first elastic member 102 to release the pressure. After the sliding plate 103 is pushed, the heat transfer chamber 101 is connected to the interior of the shell 201, and the heat transfer chamber 101 is connected to the outside through the exhaust hole 101b, so that the internal heat is smoothly discharged. After the internal pressure and high-temperature air are discharged, the sliding plate 103 is reset under the action of the first elastic member 102 to close the exhaust hole 101b, thereby protecting the internal space from dust.
[0033] Example 2, reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, and this embodiment provides an air switch for intelligent monitoring.

[0036] Preferably, a vertical cylinder 203a is provided inside the threaded cylinder ring 203, an iron core slider 203b is movably provided inside the vertical cylinder 203a, a vertical rod 203c is passed through the iron core slider 203b, and a second elastic member 203d is provided above the iron core slider 203b.
[0037] Preferably, the second elastic member 203d is sleeved on the outer wall of the vertical rod 203c, one end of the second elastic member 203d is fixedly connected to the vertical tube 203a, and the other end is fixedly connected to the top of the iron core slider 203b.
[0038] An arc extinguishing chamber 202 is provided inside the shell 201, and an arc extinguishing metal sheet group 202a is fixedly connected inside the arc extinguishing chamber 202, and a copper sheet 202b is fixedly connected to the bottom of the arc extinguishing metal sheet group 202a; a first positioning column 204b is rotatably connected to a lapped tube rod 204c; a threaded tube ring 203 is fixedly wound around the outer side of the vertical tube 203a, and the bottom end of the threaded tube ring 203 extends downward and is rotatably connected to the outer side of the first positioning column 204b and is in sliding contact with the lapped tube rod 204c; a positioning guide rail 301 is fixedly installed inside the shell 201, and a switch block 304 is rotatably installed on one side of the shell 201, and a connecting sleeve 302a and a middle slide rod 302b are installed between the positioning guide rail 301 and the switch block 304; the arc-shaped copper sheet 2 The bottom of 01c is fixedly connected to the top of the threaded barrel ring 203; the connecting sleeve 302a is preferably set to two, one of which is hinged to the sliding block 302, and the other is fixedly connected to the switch dial block 304; the two ends of the middle slide rod 302b respectively penetrate into the interior of the two connecting sleeves 302a and are slidably connected thereto; the outer side of the vertical cylinder 203a is fixedly connected to the interior of the threaded barrel ring 203, and the vertical rod 203c is fixedly connected to the core slider 203b; the two ends of the vertical rod 203c respectively extend to the outside of the two ends of the core slider 203b and extend out of the threaded barrel ring 203; the second elastic member 203d is a compression spring, and the second elastic member 203d is sleeved on the outer wall of the vertical rod 203c between the inner wall of the top end of the vertical cylinder 203a and the top of the core slider 203b.
[0039] In summary, when in use, the two junction blocks 201a are connected to the external wiring harness and energized, and the current passes through the bottom junction block 201a upward through the copper sheet 202b, the overlapping barrel rod 204c, the connecting sheet 204, the threaded barrel ring 203, the arc-shaped copper sheet 201c, and the overload protection metal sheet group 201b to reach the top junction block 201a, so that the device works;
[0040] When a short circuit occurs, the current passing through the threaded cylinder ring 203 suddenly increases, and the magnetic force generated at this time increases instantly, pushing the iron core slider 203b to rise along the vertical cylinder 203a, compressing the second elastic member 203d to drive the vertical rod 203c to push one end of the cross guide rod 303c upward to move upward and separate from the C block 303e. At this time, the other end of the cross guide rod 303c rotates to drive the block 303a to rotate downward, so that it is offset from the top of the inclined guide block 303. At this time, the balance force is broken, and under the action of the third spring 102, the connecting piece 101 is pulled to rotate around the first positioning column 204b as the axis, so that the connecting piece 204 squeezes the sliding block 302 to rise along the positioning guide rail 301 and move to the right. At this time, one end of the overlapping cylinder rod 204c is tilted and diverted from the copper sheet 202b at the bottom, realizing a short circuit, and the sliding block 302 slides upward, and the connecting sleeve 302a and the middle sliding rod 302b are used to drive the switch dial block 304 to rotate downward, realizing short circuit protection.
[0041] Example 3, reference Figure 1 to Figure 6 , which is the third embodiment of the present invention, is based on the previous embodiment, and the difference is that when overloaded, one end of the overload protection metal sheet group 201b can be deformed downward.
[0042] Specifically, a third elastic member 204a is provided on the outer wall of the connecting piece 204, one end of the third elastic member 204a is connected to the shell 201, a first positioning column 204b is provided on the outer wall of the connecting piece 204, and a lap rod 204c is movably provided on the outer wall of the first positioning column 204b.
[0043] Preferably, the top inclined surface of the connecting piece 204 contacts and cooperates with the bottom of the sliding block 302 , and a blocking block 301 a is provided below the positioning guide rail 301 .
[0044] Preferably, a clamping block 303a is clamped at one end of the inclined guide block 303, a second positioning column 303b is provided on the outer wall of the clamping block 303a, a transverse guide rod 303c is movably provided on the outer wall of the second positioning column 303b, and a fourth elastic member 303d is provided above the transverse guide rod 303c.
[0045] Preferably, a C-shaped block 303e is overlapped on the outer wall of the transverse guide rod 303c, and the top of the inner side of the C-shaped block 303e is fixedly connected to the overload protection metal sheet group 201b.
[0046] The sliding block 302 is slidably matched with the inside of the positioning guide rail 301; the bottom end of the inclined guide block 303 is fixedly connected to the sliding block 302, and the other end is clamped and matched with the outer side of the clamping block 303a; the connecting piece 204 is fixedly connected to the shell 201 by the third elastic member 204a, and the third elastic member 204a is a compression spring. The top inclined surface of the connecting piece 204 contacts and matches with the bottom of the sliding block 302; the bottom of the top wiring block 201a is installed with an overload protection metal sheet group 201b, and the overload protection metal sheet group 201 b has an arc-shaped copper sheet 201c fixedly connected to the bottom of one end, and the other end is fixedly connected to the top of the inner side of the C-block 303e; one end of the cross-guide rod 303c is rotatably connected to the outer side of the second positioning column 303b, and the other end extends to the inner side of the C-block 303e and overlaps with the bottom; the fourth elastic member 303d is a compression spring, the top end of the fourth elastic member 303d is fixedly connected to the shell 201, and the bottom end squeezes the cross-guide rod 303c and is fixedly connected to it; the clamping block 303a is fixedly installed to the outer side of one end of the cross-guide rod 303c.
[0047] In summary, when overloaded, the magnetic force generated cannot drive the vertical rod 203c. At this time, the overload causes the end of the overload protection metal sheet group 201b that contacts the C-block 303e to deform downward, driving the C-block 303e to move downward. At this time, under the action of the third elastic member 204a, the end of the horizontal guide rod 303 that contacts the C-block 303e is pushed to swing downward, so that the resistance of the block 303a to the inclined guide block 303 is reduced, breaking the balance and achieving the above-mentioned short-circuit effect. At this time, the two heat conduction chambers 101 can be used to discharge heat more quickly, so that the overload protection metal sheet group 201b can recover faster and it is easier to restore power supply, thereby realizing the device with dual protection functions of overload and short circuit, a more compact structure and rich functions, and solving the problem of circuit breaking protection when a short circuit occurs in the circuit in the prior art.
