[0002] In outdoor environments, PLC control cabinets typically require a certain level of protection to cope with complex environmental conditions. This is especially true during rainy weather, where control cabinets are typically protected from rain by their outer casing. However, this protection is limited by the outer casing alone, leaving the buttons and the joints of the control cabinet door exposed to the outside environment. In rainy weather, when a PLC control cabinet located outdoors becomes damaged and requires repair, workers must wear or hold rain gear. While this can reduce the risk of workers getting wet, it can affect hand dexterity and tactile sensitivity, making repairs more difficult and burdensome. Furthermore, rain gear only serves to shield workers from the rain. When the cabinet door is open, rainwater is likely to seep into the PLC control cabinet, increasing the risk of electrical failures such as short circuits and leakage, disrupting the normal repair process.

[0003] Therefore, in view of the above technical problems, it is necessary to provide a PLC control cabinet for outdoor environments. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, a PLC control cabinet for outdoor environments in one embodiment of the present invention includes a control cabinet body 1, a control cabinet door 101 hinged on the control cabinet body 1, and a rain shield mechanism 2 installed on the control cabinet body 1, and the rain shield mechanism 2 matches the control cabinet door 101. The rain shield mechanism 2 is used to shield the control cabinet body 1 from rain under rainy conditions, and to minimize rainwater from entering the control cabinet body 1 through the gap between the button and the control cabinet door 101, causing short circuits in the components of the control cabinet body 1 and affecting the normal use of the control cabinet body 1. When the control cabinet body 1 needs to be repaired in rainy weather, the rain shield mechanism 2 can expand the rain shield range to form a rain shelter space. The staff can perform repairs in the rain shelter space without wearing or holding rainproof equipment, which is convenient for the staff to perform repairs.

[0033] like Figures 1 to 7As shown, the rain shield mechanism 2 includes a first rain shield 201, within which a first chute 202 is defined. When maintenance personnel need to repair the control cabinet body 1 during rainy weather, pulling out the second rain shield 203 expands the rain shielding area, creating a rain shelter. The personnel can perform maintenance in the rain shelter without wearing or holding rainproof gear, which improves their operational agility and facilitates repairs of PLC control cabinets located outdoors on rainy days. A second rain shield 203, compatible with the first chute 202, is slidably connected within the first chute 202. A locking assembly compatible with the second rain shield 203 is installed within the first rain shield 201. The locking structure is used to limit the position of the first chute 202, minimizing the risk of the second rain shield 203 sliding back into or out of the first rain shield 201 during maintenance work on the control cabinet body 1, thereby disrupting normal maintenance work.

[0034] like Figures 1 to 7 As shown, a slider 205 is fixedly connected to the bottom of the second rain shield 203. A second chute 204 is defined at the bottom of the first rain shield 201 to match the slider 205. A first rain shield sheet 206 and a second rain shield sheet 207 are mounted on the bottom of the slider 205. A snap-fit ​​assembly is mounted on the first rain shield 206 to match the second rain shield sheet 207. The snap-fit ​​assembly secures the second rain shield sheet 207 to the outside of the first rain shield 206, minimizing the impact of the first and second rain shield sheets 206 and 207 on the heat dissipation of the control cabinet body 1. An auxiliary assembly is installed between the second rain shield sheet 207 and the control cabinet body 1. When the second rain shield 203 is pulled out, the control cabinet door 101 opens simultaneously with the cooperation of the auxiliary components, and the first rain shield 206 and the second rain shield 207 move forward accordingly. At this time, the first rain shield 206 can block the rain from the front, minimizing the rain from entering the control cabinet body 1 through the open control cabinet door 101. The second rain shield 207 covers the buttons, minimizing the rain from seeping into the components through the gaps between the buttons, thereby achieving the purpose of multi-faceted protection of the control cabinet body 1 during maintenance. At the same time, the expanded rain shelter allows workers to perform maintenance without wearing or holding rainproof equipment, improving hand dexterity and tactile sensation.

[0035] like Figure 5 As shown, the control cabinet body 1 is equipped with a heat dissipation mechanism 3, which is installed on the outside of the control cabinet body 1. The heat dissipation mechanism 3 collects and stores rainwater, and uses the principle of a communicating vessel to allow the rainwater to flow to the control cabinet body 1, thereby assisting in heat dissipation of the control cabinet body 1. This minimizes the possibility that the heat dissipation components within the control cabinet body 1, such as heat sinks, cannot maintain the temperature within the control cabinet body 1 within a reasonable range during the operation of the components within the control cabinet body 1, resulting in a high temperature within the control cabinet body 1 and affecting the normal operation of the components within the control cabinet body 1.

[0036] like Figure 5 As shown, the heat dissipation mechanism 3 includes a water inlet hopper 303, with a pipe 302 fixedly connected to the bottom of the water inlet hopper 303. A water tank 301 is mounted at the bottom of the pipe 302. The side of the water tank 301 near the control cabinet body 1 is connected to a heat dissipation pipe 305, which is located inside the outer shell of the control cabinet body 1. Based on the principle of communicating vessels, rainwater in the water tank 301 flows into the heat dissipation pipe 305, cooling and dissipating the control cabinet body 1 through the rainwater in the heat dissipation pipe 305, thereby maintaining the temperature of the control cabinet body 1 within a range that is conducive to component operation.

[0037] like Figure 5 As shown, the heat dissipation mechanism 3 includes an anti-clogging net 304 that matches the water inlet bucket 303, and the anti-clogging net 304 is installed on the water inlet bucket 303. The anti-clogging net 304 can prevent fallen leaves from blocking the water inlet bucket 303 to a certain extent, affecting rainwater collection.

[0038] Preferably, the anti-clogging net 304 is in the shape of an inverted cone. The inverted cone-shaped anti-clogging net 304 can make fallen leaves slide down to the surrounding areas, and avoid fallen leaves piling up on the anti-clogging net 304 as much as possible, which would affect the normal collection of rainwater.

[0039] like Figure 5 As shown, the first rain shield 201 is provided with a water collecting groove 306 that matches the water inlet bucket 303. The water collecting groove 306 guides the rainwater collected on the first rain shield 201 into the water inlet bucket 303, making the rainwater collection efficiency higher.

[0040] like Figures 7 and 8 As shown, the locking assembly includes a first clamping block 211, which is installed on the second rain shield 203, and the locking assembly includes a third clamping block 213 and a second clamping block 212 that matches the first clamping block 211. When the second rain shield 203 is pulled out, the second clamping block 212 supports the first clamping block 211, and then supports the second rain shield 203, so as to prevent the second rain shield 203 from sliding back into the first rain shield 201 during maintenance as much as possible. The second clamping block 212 and the third clamping block 213 are installed inside the first rain shield 201, and a limiting groove that matches the third clamping block 213 is provided on the second rain shield 203. When the second rain shield 203 is pulled out, the third clamping block 213 engages with the limiting groove on the second rain shield 203, so as to prevent the second rain shield 203 from sliding out of the first rain shield 201 as much as possible, and the second rain shield 203 hits the maintenance personnel and causes an accident.

[0041] like Figure 1As shown, the engaging assembly includes an engaging groove 214, in which an engaging groove 214 matching the engaging groove 214 is installed, and an engaging rod 215 is fixedly connected to the second rain shield 207. When the staff needs to repair the control cabinet body 1 in rainy weather, the engaging rod 215 is pulled out from the engaging groove 214, so that the second rain shield 207 shields the periphery of the control cabinet door 101 and prevents rainwater from seeping into the control cabinet body 1 as much as possible. When the control cabinet body 1 does not need to be shielded from rain, the engaging rod 215 is engaged with the engaging groove 214 to prevent the second rain shield 207 from affecting the heat dissipation of the control cabinet body 1, causing the temperature of the control cabinet body 1 to be too high, and affecting the normal use of the control cabinet body 1.

[0042] like Figure 1 As shown, a handle is installed on the second rain shield 203. The handle is convenient for the staff to pull out the second rain shield 203.

[0043] like Figure 1 、 Figure 4 As shown, the auxiliary assembly includes a slide rail 208, which is mounted on the side of the first rain shield 206 close to the control cabinet body 1. The control cabinet door 101 is equipped with a connecting rod 209 and a connecting ball 210 that match the slide rail 208. The connecting rod 209 is hinged to the second rain shield 203. With the cooperation of the auxiliary assembly, when the staff pulls the handle, they can drive the control cabinet door 101 and the second rain shield 203 to open simultaneously, improving the convenience during maintenance.

[0044] During use, when the staff needs to repair the control cabinet body 1 on a rainy day, the handle is pulled away from the control cabinet body 1, and the second rain shield 203, the first rain shield piece 206 and the second rain shield piece 207 move outward. At the same time, the auxiliary component drives the control cabinet door 101 to open, so that the maintenance work can proceed normally. At this time, the second rain shield 203 expands the rain protection range, and the space where the staff can stand to shelter from the rain is increased. At the same time, the first rain shield piece 206 and the second rain shield piece 207 respectively shield the control cabinet body 1 from the front and one side, avoiding rainwater from entering the control cabinet body 1 from the control cabinet door 101 and buttons as much as possible, causing electrical faults such as short circuit and leakage, causing damage to components in the PLC control cabinet for outdoor environments, and affecting the normal maintenance of the control cabinet body 1.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0046] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
