Description

Technical Field

[0001] This invention relates to the field of control cabinet technology, and more particularly to a PLC automation control cabinet. Background Technology

[0002] PLC control cabinets can complete equipment automation and process automation control, realize perfect network functions, and have the characteristics of stable performance, scalability, and strong anti-interference. However, when the cabinet door is closed, the wiring folds are prone to being pinched or worn.

[0003] The prior art (CN213586620U) discloses an industrial automation PLC control cabinet, including a cabinet body with a cabinet door on one side; a connector, which connects the mounting plate to the inner wall of the cabinet cavity; an operation panel, which is connected to the inside of the cabinet door and connected to the control element by a connecting wire; and an anti-damage component, which is connected between the operation panel and the inner wall of the cabinet to wrap and protect the connecting wire. The anti-damage component between the cabinet door and the cabinet body facilitates the isolation and protection of the connecting wire, preventing damage or wear to the connecting wire during the opening and closing of the cabinet door.

[0004] However, with the above method, since the cabinet is not equipped with a heat dissipation device, the temperature of the electronic components inside the cabinet will continue to rise during long-term operation, which will reduce the normal lifespan of the internal electronic components. Summary of the Invention

[0005] The purpose of this invention is to provide a PLC automation control cabinet, which aims to solve the problem that in existing industrial automation PLC control cabinets, the temperature of the electronic components inside the cabinet will continue to rise during long-term operation due to the lack of heat dissipation devices, thereby reducing the normal lifespan of the internal electronic components.

[0006] To achieve the above objectives, the present invention provides a PLC automation control cabinet, including a cabinet body and working components.

[0007] The working components include cabinet doors, fasteners, multiple telescopic components, multiple storage racks, a suction fan, an air inlet pipe, a replaceable dustproof structure, multiple heat dissipation structures, and a gas exchange network;

[0008] The cabinet door is rotatably connected to the cabinet body and located on one side of the cabinet body; the fixing component is located on one side of the cabinet body; multiple telescopic components are respectively located inside the cabinet body; multiple storage racks are respectively fixedly connected to multiple telescopic components and located on one side of multiple telescopic components; the suction fan is fixedly connected to the cabinet body and located on one side of the cabinet body; the air inlet pipe is connected to the suction fan and located on one side of the suction fan; the replaceable dustproof structure is located on one side of the suction fan; multiple heat dissipation structures are respectively located on one side of multiple storage racks; the gas exchange network is fixedly connected to the cabinet body and located on one side of the cabinet body.

[0009] The fixing component includes a mating iron block, a fixing frame, and an electromagnet. The mating iron block is fixedly connected to the cabinet door and located on one side of the cabinet door; the fixing frame is fixedly connected to the cabinet body and located on one side of the cabinet body; and the electromagnet is fixedly connected to the fixing frame and located on one side of the fixing frame.

[0010] The telescopic component includes an electric telescopic cylinder and a push block. The electric telescopic cylinder is fixedly connected to the cabinet and located inside the cabinet. The push block is fixedly connected to the output end of the electric telescopic cylinder and to the placement rack, and is located on one side of the electric telescopic cylinder.

[0011] The heat dissipation structure includes a fixed frame, a jet nozzle, and an air supply hose. The fixed frame is fixedly connected to the placement frame and is located on the side of the placement frame. The jet nozzle is fixedly connected to the fixed frame and is located on one side of the fixed frame. The air supply hose is connected to both the jet nozzle and the suction fan and is located between the jet nozzle and the suction fan.

[0012] The PLC automation control cabinet also includes multiple movable structures, which are respectively arranged on one side of the cabinet.

[0013] The movable structure includes a height adjustment component, a mounting plate, and casters. The height adjustment component is located on one side of the cabinet. The mounting plate is fixedly connected to the height adjustment component and is located on one side of the height adjustment component. The casters are located on one side of the mounting plate.

[0014] The height adjustment component includes a support cylinder, a hydraulic cylinder, and a telescopic rod. The support cylinder is fixedly connected to the cabinet and located on one side of the cabinet. The hydraulic cylinder is fixedly connected to the support cylinder and located on one side of the support cylinder. The telescopic rod is fixedly connected to the output end of the hydraulic cylinder and to the mounting plate, and located on one side of the hydraulic cylinder.

[0015] This invention discloses a PLC automation control cabinet in which electronic components for PLC automation control are respectively mounted on multiple racks. The cabinet door is then fastened to the cabinet body using a fixing device, ensuring a tight fit between the door and the cabinet body. When the electronic components inside the cabinet generate heat during operation, the exhaust fan, through the air inlet pipe and the replaceable dustproof structure, draws external dust into the multiple heat dissipation structures. These structures rapidly cool the electronic components on the racks, removing the heat emitted by the components, which is then quickly exhausted through the gas exchange network. This solves the problem in existing industrial automation PLC control cabinets where the lack of a heat dissipation device in the cabinet body leads to a continuous increase in temperature of the internal electronic components during prolonged operation, resulting in a reduced lifespan.

Detailed Implementation

[0024] The first embodiment of this application is as follows:

[0025] Please see Figures 1-3 ,in, Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention. Figure 2 This is a front view of the entire first embodiment of the present invention. Figure 3 This is another structural schematic diagram of the overall first embodiment of the present invention.

[0026] This invention provides a PLC automation control cabinet, comprising a cabinet body 101 and working components. The working components include a cabinet door 102, fixing components 103, multiple telescopic components 104, multiple storage racks 105, a suction fan 106, an air inlet pipe 107, a replaceable dustproof structure 108, multiple heat dissipation structures 109, and a gas exchange network 110. The fixing component 103 includes a mating iron block 111, a fixing frame 112, and an electromagnet 113. The telescopic components 104 include an electric telescopic cylinder 114 and a push block 115. The heat dissipation structures 109 include... The replaceable dustproof structure 108 includes a mounting frame 119, two mounting parts 120, and a filter screen 121. The mounting parts 120 include a bracket 122, a locking screw 123, and a stop block 124. The aforementioned solution solves the problem that in existing industrial automation PLC control cabinets, the temperature of the electronic components inside the cabinet 101 will continue to rise during long-term operation because the cabinet 101 is not equipped with a heat dissipation device, thus reducing the normal lifespan of the internal electronic components.

[0027] In this specific embodiment, the cabinet 101 is used to support the assembly of the working components.

[0028] The cabinet door 102 is rotatably connected to the cabinet body 101 and located on one side of the cabinet body 101; the fixing member 103 is located on one side of the cabinet body 101; multiple telescopic members 104 are respectively located inside the cabinet body 101; multiple placement racks 105 are respectively fixedly connected to multiple telescopic members 104 and located on one side of multiple telescopic members 104; the suction fan 106 is fixedly connected to the cabinet body 101 and located on one side of the cabinet body 101; the air inlet pipe 107 is connected to the suction fan 106 and located on one side of the suction fan 106; the replaceable dustproof structure 108 is located on one side of the suction fan 106; multiple heat dissipation structures 109 are respectively located on one side of multiple placement racks 105; the gas exchange network 110 is fixedly connected to the cabinet body 101 and located on one side of the cabinet body 101, housing electronic components used for PLC automation control. The cabinet is installed on multiple racks 105, and then the cabinet door 102 is fastened to the cabinet body 101 by the fastener 103 so that the cabinet door 102 fits tightly against the cabinet body 101. When the electronic components inside the cabinet body 101 generate heat during operation, the suction fan 106 is turned on and the external dust is sucked into multiple heat dissipation structures 109 through the air inlet pipe 107 and the barrier of the replaceable dustproof structure 108. The multiple heat dissipation structures 109 respectively cool down the electronic components on multiple racks 105, remove the heat emitted by the electronic components, and then quickly exhaust it through the gas exchange network 110. This solves the problem that in existing industrial automation PLC control cabinets, the temperature of the electronic components inside the cabinet body 101 will continue to rise during long-term operation because the cabinet body 101 is not equipped with a heat dissipation device, which leads to a reduction in the normal life of the internal electronic components.

[0029] Secondly, the mating iron block 111 is fixedly connected to the cabinet door 102 and located on one side of the cabinet door 102; the fixing frame 112 is fixedly connected to the cabinet body 101 and located on one side of the cabinet body 101; the electromagnet 113 is fixedly connected to the fixing frame 112 and located on one side of the fixing frame 112. When the cabinet door 102 is in contact with the cabinet body 101, the electromagnet 113 is energized and has electromagnetic force to attract the mating iron block 111, so that the cabinet door 102 is tightly attached to the cabinet body 101.

[0030] Meanwhile, the electric telescopic cylinder 114 is fixedly connected to the cabinet 101 and located inside the cabinet 101; the push block 115 is fixedly connected to the output end of the electric telescopic cylinder 114 and to the placement rack 105, and is located on one side of the electric telescopic cylinder 114. When assembling electronic components, the electric telescopic cylinder 114 is controlled to drive the push block 115 to push the placement rack 105 to move, push the placement rack 105 out, and then assemble the electronic components. After the assembly is completed, the electric telescopic cylinder 114 is controlled to retract the placement rack 105, making it more convenient to assemble electronic components.

[0031] In addition, the fixing bracket 116 is fixedly connected to the placement bracket 105 and is located on the side of the placement bracket 105; the jet head 117 is fixedly connected to the fixing bracket 116 and is located on one side of the fixing bracket 116; the air supply hose 118 is connected to the jet head 117 and the suction fan 106 respectively, and is located between the jet head 117 and the suction fan 106. The fixing bracket 116 is used to support the installation of the jet head 117. The jet head 117 receives the airflow transmitted by the air supply hose 118 and sprays it directionally onto the electronic components on the placement bracket 105, quickly removing the heat emitted by the electronic components and achieving a rapid cooling effect.

[0032] Furthermore, the replaceable dustproof structure 108 includes an assembly frame 119, two fittings 120, and a filter screen 121. The assembly frame 119 is fixedly connected to the air inlet pipe 107 and is located on one side of the air inlet pipe 107. The two fittings 120 are respectively disposed on both sides of the assembly frame 119. The filter screen 121 is located on one side of the assembly frame 119. The filter screen 121 is attached to the assembly frame 119, and then the fittings 120 on both sides are operated to contact the two sides of the filter screen 121 to complete the assembly of the filter screen 121. The filter screen 121 blocks external dust and prevents dust from entering the suction fan 106 through the air inlet pipe 107. When replacing, the filter screen 121 can be disassembled by operating the fittings 120 to loosen it.

[0033] Finally, the assembly 120 includes a bracket 122, a locking screw 123, and a stop block 124. The bracket 122 is fixedly connected to the assembly frame 119 and is located on the side of the assembly frame 119. The locking screw 123 is threadedly connected to the bracket 122 and is located on one side of the bracket 122. The stop block 124 is fixedly connected to the locking screw 123 and is located on one side of the locking screw 123. The bracket 122 is used to support the rotation of the locking screw 123. When the filter screen 121 is placed on the assembly frame 119, the locking screw 123 is twisted so that the stop block 124 abuts against the filter screen 121 to complete the fixing of the filter screen 121. When the filter screen 121 needs to be replaced, the locking screw 123 is twisted to loosen the filter screen 121 for disassembly.

[0034] In using the PLC automation control cabinet described in this embodiment, electronic components for PLC automation control are respectively installed on multiple placement racks 105. The cabinet door 102 is operated to engage with the cabinet body 101. When the electromagnet 113 is energized, it exerts electromagnetic force to attract the mating iron block 111, causing the cabinet door 102 to fit tightly against the cabinet body 101. The filter screen 121 is placed on the assembly frame 119. Twisting the locking screw 123 causes the abutment block 124 to contact the filter screen 121, thus fixing the filter screen 121. When the electronic components inside the cabinet body 101 generate heat during operation, the suction fan 106 is turned on, and the heat is released through the... The air inlet duct 107, together with the filter screen 121 assembled with the assembly frame 119, blocks the intake of external dust. The jet nozzle 117 receives the airflow transmitted by the air supply hose 118 and directs it toward the electronic components on the placement rack 105, quickly removing the heat emitted by the electronic components and achieving a rapid cooling effect. The air is then quickly discharged through the gas exchange network 110, achieving gas exchange to rapidly reduce the temperature of the electronic components themselves. This solves the problem in existing industrial automation PLC control cabinets where the temperature of the electronic components inside the cabinet 101 continuously rises during long-term operation due to the lack of a heat dissipation device, thus reducing the normal lifespan of the internal electronic components.

[0035] The second embodiment of this application is as follows:

[0036] Please see Figures 4-6 ,in, Figure 4 This is a schematic diagram of the overall structure of the second embodiment of the present invention.

The support cylinder 205 is used to support the installation of the hydraulic cylinder 206 and control the hydraulic cylinder 206 to drive the telescopic rod 207 to extend and retract, thereby adjusting the height of the cabinet 101.

[0041] In the PLC automation control cabinet described in this embodiment, the hydraulic cylinder 206 is controlled to drive the telescopic rod 207 to extend and retract, adjusting the height of the cabinet 101.
