[0002] The metal casing of electrical equipment, concrete, electric poles, etc. may be charged due to insulation damage. In order to prevent this from endangering personal safety and avoiding electric shock accidents, the metal casing of the electrical equipment is connected to the grounding device for protection. When the human body touches the electrical equipment with the casing charged, since the contact resistance of the grounding body is much smaller than the resistance of the human body, most of the current enters the earth through the grounding body, and only a small part flows through the human body, which will not cause harm to human life.

[0003] At present, an existing grounding wire protection box (such as patent number: CN201528176U) discloses a grounding wire protection box, which is characterized in that: the grounding wire protection box as a whole includes an outer shell and a crank connected to the inside of the outer shell; a rotating rod for winding the grounding wire is provided in the outer shell, and the rotating rod is connected to the crank; the grounding wire protection box has a simple and reasonable structure, is easy to use, reduces labor, improves work efficiency, and reduces the risk factor.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the existing grounding protection device can only protect the operator by conducting the current carried by the equipment casing into the ground through a wire. It is impossible to intuitively see the size of the leakage situation, and it is impossible to judge whether the leakage situation is within a safe and reasonable range, whether it will cause damage to the equipment, and it is impossible to protect the automation equipment while protecting the operator.

If the current is abnormally large, the fuse will burn out and the current will be guided to the ground along the indicator light, the resistor, the second conductive rod and the terminal. At the same time, the indicator light will light up to remind the operator that the leakage is abnormal. The fuse will be melted by a large current to light up the indicator light, so that the leakage can be discovered and handled by the operator in time when it exceeds the normal range.

[0014] 2. The door is fixed to the protective shell by a magnet on the non-rotating end. When the staff finds abnormal leakage, they will take corresponding measures in time.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in the embodiment of the present application effectively solves the technical problems of the existing grounding protection device, which conducts the current carried by the equipment casing into the ground through a wire, and can only protect the operator, but cannot intuitively see the size of the leakage situation, cannot judge whether the leakage situation is within a safe and reasonable range, whether it will cause damage to the equipment, and cannot protect the operator while also protecting the automation equipment. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides an electromechanical machinery manufacturing automation protection device, comprising a protection shell 1, a first conductive rod 4 is fixedly mounted on the top end of the protection shell 1, and a metal sheet 2 is fixedly mounted on the side end of the protection shell 1.

[0026] An indicator light 3 is fixedly installed on the top of the protective shell 1 on one side of the first conductive rod 4, a resistor 7 is fixedly installed on the inner wall of the protective shell 1 at the bottom end of the indicator light 3, a fuse box 5 is fixedly installed on the inner wall of the protective shell 1 on one side of the resistor 7, and a fuse core 6 is fixedly installed on the inner wall of the fuse box 5; the fuse box 5 is connected to the first conductive rod 4.

[0027] A second conductive rod 8 is fixedly installed at the bottom end of the fuse box 5, and a terminal 9 is fixedly installed at the bottom end of the second conductive rod 8; the terminal 9 is a three-way structure for easy wire connection, and a compartment door 11 is rotatably installed at the side end of the protective shell 1, and a pressure block 12 is fixedly installed at the side end of the compartment door 11.

[0028] Working principle:

[0029] The first step is to fix the device on the metal shell of the automation equipment, and then insert the ground wire from the small hole at the bottom of the protective shell 1 into the interior of the terminal 9 and tighten it with screws. During the automated production process, the metal shell may carry a certain current due to various reasons. The device fixed on the equipment will guide the current along the metal sheet 2, the first conductive rod 4, the fuse 6, the second conductive rod 8 and the terminal 9 to the ground. If the current is abnormally large, the fuse 6 will be burned, and the current will be guided to the ground along the indicator light 3, the resistor 7, the second conductive rod 8 and the terminal 9. At the same time, the indicator light 3 lights up to remind the operator that the leakage is abnormal. The fuse 6 is melted by a large current to light up the indicator light 3, so that the leakage can be discovered and handled by the operator in time when it exceeds the normal range.

[0030] In the second step, the compartment door 11 is fixed to the protective shell 1 by a magnet on one side of the non-rotating end. When the staff finds abnormal leakage, they will take corresponding measures in time. After completion, the compartment door 11 is rotated, the inside of the protective shell 1 is opened, the fuse 6 is buckled out, and a new fuse 6 is inserted, and the compartment door 11 is closed. Similarly, if the power of the equipment is changed, the fuse 6 of appropriate specifications can be replaced. It can effectively prevent false triggering. The fuse 6 is replaced by opening the compartment door 11 to complete the rapid reset of the device, so that the protection device can be quickly reset after the leakage problem of the automation equipment is solved, and the effect of being able to cope with automation equipment of different powers by replacing fuses 6 of different specifications.
