Description

Technical Field

[0001] This utility model relates to the field of PLC control cabinet technology, and in particular to a PLC control cabinet with circulating ventilation. Background Technology

[0002] PLC control cabinets refer to programmable control cabinets. A control cabinet is a complete set of control cabinets, an electrical cabinet that can control motor switches. PLC control cabinets have protection functions such as overload, short circuit, and phase loss protection. They are characterized by compact structure, stable operation, and complete functions. They can be combined according to the actual control scale to realize single cabinet automatic control or multiple cabinets can be connected to form a distributed control system (DCS) through industrial Ethernet or industrial fieldbus networks. PLC control cabinets can adapt to industrial automation control applications of various sizes and are widely used in industries such as power, metallurgy, chemical, papermaking, and environmental wastewater treatment.

[0003] The applicant found through a search that a Chinese patent discloses "a PLC control cabinet with a circulating ventilation structure", with the publication number "CN221467144U". This patent mainly uses a strip block to block the normally closed switch, so the lamp is not lit. Turning the handle opens the cabinet door, the normally closed switch closes, and the lamp lights up. The motor below drives the cooling fan to rotate to draw in air, and the motor above drives the cooling fan to rotate in the opposite direction to exhaust air. The air drawn in from below enters the cabinet evenly through the slots on the diffuser box.

[0004] The aforementioned device, through a series of structural designs, can provide lighting inside the cabinet for easy use by staff and facilitate heat dissipation to cool the interior of the cabinet. However, cleaning the ventilation screen requires disassembling the air intake screen, and the cleanliness of the air intake screen cannot be guaranteed in real time. After prolonged use, the accumulation of dust on the air intake screen will affect the airflow and consequently the heat dissipation effect inside the device, resulting in low practicality of the device in use. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 5 As shown, a circulating ventilation PLC control cabinet according to the first aspect embodiment of the present invention includes a control cabinet body 1, support legs 8 fixedly connected to the four corners of the bottom surface of the control cabinet body 1, two fans 11, a door 6 located on one side of the control cabinet body 1, and a handle 7 fixedly connected to the surface of the door 6. The bottom surface of the control cabinet body 1 is provided with multiple air inlets 12. A partition 9 is fixedly connected to opposite sides of the inner wall of the control cabinet body 1. The top surface of the partition 9 is provided with multiple air outlets 10. A transmission component 2 is provided on one side of the control cabinet body 1, which can rotate to cause the two fans 11 to reciprocate. A dust removal component 3 is provided at the bottom of the control cabinet body 1, which can reciprocate under the action of the transmission component 2 to clean the dust adsorbed on the surface of the air inlets 12.

[0023] In the above embodiments, it should be noted that the fan 11 is a mature existing technology, and is generally composed of a motor and fan blades.

[0024] The technical effects achieved by the above embodiments are as follows: the transmission component 2 can drive the two fans 11 to move back and forth, thereby expanding the air blowing range of the fans 11 and improving the heat dissipation efficiency. At the same time, while the transmission component 2 causes the two fans 11 to move back and forth, it can also cause the dust removal component 3 to move back and forth on the bottom surface of the control cabinet body 1 to remove the dust on the air inlet 12 on the bottom surface of the control cabinet body 1, thereby keeping the air inlet 12 clean in real time and avoiding the air inlet 12 from accumulating too much dust, which would affect the air intake and heat dissipation effect of the device. Example 2

[0025] like Figures 2 to 5As shown, a PLC control cabinet with circulating ventilation includes all the contents of Embodiment 1. In addition, the transmission assembly 2 includes a motor 201, one side of which is fixedly connected to one side of the control cabinet body 1. The output end of the motor 201 penetrates the surface of the control cabinet body 1 and extends into the interior of the control cabinet body 1. The transmission assembly 2 also includes a bidirectional circulating screw 206 and a first slide rod 205. One end of the bidirectional circulating screw 206 is fixedly connected to the output end of the motor 201. Two moving blocks 209 are threaded onto the wall of the bidirectional circulating screw 206. The top surfaces of the two moving blocks 209 are fixedly connected to the bottom surfaces of the two fans 11, respectively. The side of the bidirectional circulating screw 206 away from the motor 201 penetrates the inner wall of the control cabinet body 1 and extends to one side of the surface of the control cabinet body 1. The end of the bidirectional circulating screw 206 extending to one side of the surface of the control cabinet body 1 is fixedly connected to... The transmission assembly 2 includes a first gear 207, a bidirectional circulating screw 206 whose rod wall is rotatably connected to the inner wall of the control cabinet body 1, a first slide rod 205 whose opposite ends are fixedly connected to opposite sides of the inner wall of the control cabinet body 1, and a first slide rod 205 whose rod wall is slidably connected to the rod walls of two moving blocks 209. The transmission assembly 2 also includes a reciprocating screw 204 and two vertical plates 202. The top surfaces of the two vertical plates 202 are fixedly connected to the bottom surface of the control cabinet body 1. One end of the reciprocating screw 204 is rotatably connected to one side of one of the vertical plates 202. The other end of the reciprocating screw 204 passes through one side of the other vertical plate 202 and is fixedly connected to a second gear 208. The top surface of the second gear 208 meshes with the bottom surface of the first gear 207. The transmission assembly 2 also includes a second slide rod 203 whose opposite ends are fixedly connected to opposite sides of the two vertical plates 202.

[0026] The technical effect achieved by the above embodiment is as follows: When the control cabinet body 1 needs to be circulated for ventilation, the motor 201 is started, and the motor 201 drives the bidirectional circulating screw 206 to rotate. With the rotation of the bidirectional circulating screw 206 and the setting of the first slide bar 205, the two moving blocks 209 can be moved back and forth on the bidirectional circulating screw 206. At the same time, the fan 11 sends the air out through the air outlet 10, which expands the air blowing range of the fan 11 and improves the effect of circulating ventilation. While the bidirectional circulating screw 206 is rotating, it can drive the first gear 207 to rotate. Then, the first gear 207 and the second gear 208 cooperate to make the reciprocating screw 204 rotate. After being accommodated, the rotation of the reciprocating screw 204 and the limiting of the second slide bar 203 can make the dust removal component 3 move back and forth along the rod wall of the reciprocating screw 204, thereby achieving the effect of removing dust from the surface of the air inlet 12 on the bottom surface of the control cabinet body 1. Example 3

[0027] like Figure 4 and Figure 5As shown, a circulating ventilation PLC control cabinet includes all the contents of Embodiment 2. In addition, the dust removal component 3 includes a connecting plate 301, the inner wall of the connecting plate 301 is threadedly connected to the rod wall of the reciprocating screw 204, and the inner wall of the connecting plate 301 is slidably connected to the rod wall of the second slide rod 203. The dust removal component 3 also includes a mounting plate 302, the bottom surface of the mounting plate 302 is fixedly connected to the top surface of the connecting plate 301, and a brush bristle 303 is fixedly connected to the top surface of the mounting plate 302. The top surface of the brush bristle 303 contacts the bottom surface of the control cabinet body 1.

[0028] The technical effect achieved by the above embodiment is that when the reciprocating screw 204 rotates, it can cooperate with the connecting plate 301, so that the connecting plate 301 moves back and forth under the rotation of the reciprocating screw 204. Then, the brush 303 is used to clean the air inlet 12 at the bottom of the control cabinet body 1, thereby preventing dust from adhering to the air inlet 12 and affecting the air intake volume of the device during circulating ventilation. Example 4

[0029] like Figure 1 and Figure 2 As shown, a circulating ventilation PLC control cabinet includes all the contents of Embodiment 3. In addition, an air outlet duct 4 is fixedly connected to the top surface of the control cabinet body 1. The air outlet duct 4 communicates with the interior of the control cabinet body 1, and a dustproof net 5 is fixedly connected to the inner wall of the air outlet duct 4.

[0030] The technical effect achieved by the above embodiment is that the air outlet duct 4 can exhaust the hot air inside the control cabinet body 1 when the outside wind enters from the bottom, thereby achieving the effect of circulating ventilation inside the control cabinet body 1.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
