PLC control cabinet for preventing rodents

Abstract

The invention relates to a PLC control cabinet for preventing rodents. The PLC control cabinet is composed of a cabinet door part, a cabinet body part and a cabinet bottom part, wherein the cabinet door part, the cabinet body part and the cabinet bottom part are respectively provided with a blocking device for preventing the rodents from entering; the cabinet door part and the cabinet body part are respectively provided with a ventilation and heat dissipation device; and the cabinet bottom part is assembled by several bottom plates and is convenient to disassembly, and a waterproof connector is installed at the cabinet bottom part for circuits to be inserted into the cabinet body. The PLC control cabinet for preventing the rodents provided by the invention is characterized in that the blocking device for preventing the rodents from entering is designed; the structure is simple, the disassembly is convenient, a threading operation is facilitated, and the maintenance cost is low, so thatthe rodents can be effectively prevented from entering the PLC control cabinet while ventilation and heat dissipation are guaranteed, and electrical components and circuits in the PLC control cabinetare protected.

Description

technical field [0001] The invention relates to a functional PLC control cabinet, in particular to a rodent-proof PLC control cabinet. technical background [0002] In the field of automatic control, the PLC control cabinet carries the core equipment of automatic control technology. One of the PLC programmer modules is worth thousands or even tens of thousands, which is the heart of the entire automatic control system. The loss is immeasurable. However, one of the main factors affecting the self-control failure is the excrement of rodents such as mice, which causes short-circuit damage to electronic products. How to completely block rodents such as mice from the control cabinet is a solution to this problem. effective solution to the problem. [0003] At present, there are many ways to prevent rodents such as mice in the control cabinet. There are two main methods. One is to drive away or block rodents such as mice from entering the cabinet, and the other is to kill them th...

[0002] In the field of automatic control, the PLC control cabinet carries the core equipment of automatic control technology. One of the PLC programmer modules is worth thousands or even tens of thousands, which is the heart of the entire automatic control system. The loss is immeasurable. However, one of the main factors affecting the self-control failure is the excrement of rodents such as mice, which causes short-circuit damage to electronic products. How to completely block rodents such as mice from the control cabinet is a solution to this problem. effective solution to the problem

[0003] At present, there are many ways to prevent rodents such as mice in the control cabinet. There are two main methods. One is to drive away or block rodents such as mice from entering the cabinet, and the other is to kill them through the power grid. The specific implementation effect is compared. Good have the following several: 1, install electronic drive away device, its principle is to send the ultrasonic wave that stimulates rodents such as mouse to drive away by electronic product, this method can play drive away function, compares the present invention to have some defects, Electronic products need power supply, and rodents such as mice will appear again after a long-term power failure, and the radiation range is limited, so it is impossible to prevent 100% of rodents such as mice from entering the cabinet; Install the power grid at the line port, and use the infrared probe to detect rodents such as mice and kill them by electric shock. This method also has the problem of needing uninterrupted power supply, and the structure is more complicated and the maintenance cost is higher; 3. Filling plugging, this method It can effectively prevent rodents such as mice from entering the cabinet, but it is inconvenient for later maintenance work
