Figures 1 to 6As shown, a preferred embodiment is shown, which shows an engineering distribution box, including a chassis 1, an air inlet box 2, a guide plate 3, a water baffle 4 and a fixing rod 5. An air inlet 6 is provided on one side of the chassis 1, and a fan is provided in the air inlet 6. An air inlet box 2 is provided on one side of the chassis 1 facing the air inlet 6. A plurality of air outlets 7 are provided on the other side of the chassis 1. Two fixing rods 5 are provided on both sides of the plurality of air outlets 7. A plurality of water baffles 4 are provided between the two fixing rods 5. Each water baffle 4 faces one air outlet 7 respectively, and both sides of each water baffle 4 are connected to the two fixing rods 5. A guide plate 3 is provided at both ends and on the upper side of each air outlet 7. In this embodiment, see Figure 4 As shown, the front end of the chassis 1 is provided with an opening and closing door for opening or closing the chassis 1, wherein the lower end of the chassis 1 is provided with supporting feet for supporting the chassis 1.

[0028] In this embodiment, the fan is a negative pressure fan, which is used to pump air into the chassis 1, and then the air leaves the chassis 1 through the air outlet 7, and can take away the heat inside the chassis 1. The fan in this embodiment can be connected to the power module 8 inside the chassis 1, wherein the structure inside the chassis 1 is an existing structure and is not limited here. The inside of the chassis 1 is used to place electrical components.

[0029] The fan can be controlled by the PLC controller 9 on the inner wall of the chassis 1. For example, a temperature sensor 10 is set on the inner wall of the chassis 1 to detect the temperature inside the chassis 1. The temperature sensor 10 and the fan are connected to the PLC controller 9. When the detected temperature inside the chassis 1 is higher than a specified value, the PLC controller 9 can automatically control the fan to work. When the detected temperature inside the chassis 1 is lower than a specified value, the PLC controller 9 can control the fan to stop working.

[0030] When in use, the fan is controlled to start working, and then the fan delivers external air into the chassis 1 through the air inlet 6, and then exhausts it from the air outlet 7, which can take away the heat inside the chassis 1.

[0031] Further, as a preferred embodiment, the air inlet box 2 includes a box body 11 and a filter 12 disposed in the box body 11. A first opening is provided at one end of the box body 11, and a second opening is provided at the lower end of the box body 11. One end of the box body 11 is attached to an outer wall of one side of the chassis 1. Slots are provided on the inner walls on both sides of the box body 11 and on the inner wall at the other end. The filter 12 is disposed in the slots. In this embodiment, a sealing gasket and a waterproof cover 22 are also included. A sealing gasket is provided on the side of the filter 12 close to the chassis 1, and the sealing gasket is abutted against the side wall of the chassis 1. An annular waterproof cover 22 is provided on the outer wall of one side of the chassis 1 facing the air inlet 6, and the waterproof cover 22 is located in the box body 11. The specific structure of the air inlet box 2 can be found in Figure 3As shown, the external control enters the air inlet box 2 after being filtered by the filter 12. The filter 12 cooperates with the chassis 1 through a sealing gasket, so that the filter 12 and the chassis 1 can be sealed. The filter 12 is arranged in the card slot, which is convenient for the removal and installation of the filter 12. The outer edge of the air inlet box 2 is provided with a connecting plate, and the connecting plate and the side wall of the chassis 1 can be connected by screws, so that the air inlet box 2 is installed on the chassis 1.

[0032] Further, as a preferred embodiment, it also includes breathable cotton 13, and each air outlet 7 is provided with breathable cotton 13. Figure 5 As shown, the breathable cotton 13 is filled in the air outlet 7, which is breathable and can absorb water to prevent rainwater from penetrating into the chassis 1 from the air outlet 7. The staff can replace the breathable cotton 13 regularly as needed to prevent the air outlet 7 from being blocked by the water absorption port of the breathable cotton 13.

[0033] Further, as a preferred embodiment, each guide plate 3 includes a fixed plate 14 and an arc plate 15 integrally arranged at both ends of the fixed plate 14, and the fixed plate 14 and the arc plate 15 are arranged on the side wall of the chassis 1, wherein the fixed plate 14 is located on the upper side of the air outlet 7, and the two arc plates 15 are located on both sides of the air outlet 7. A baffle 16 is provided on one side of the fixed plate 14 and the arc plate 15, and each fixed plate 14 is detachably connected to the chassis 1 by bolts. Figure 6 As shown, a guide groove 17 is formed between the baffle plate 16, the fixing plate 14 and the arc plate 15. Rainwater on the side wall of the chassis 1 can enter the guide groove 17 and be discharged along the guide groove 17, thereby preventing rainwater from entering the air outlet 7. Secondly, the baffle plate 4 is arranged in an arc shape as a whole and faces the air outlet 7. For details, see Figure 3 As shown, it is possible to prevent rainwater from being blown into the air outlet 7.

[0034] In this embodiment, see Figure 3 As shown, a support plate 18 is provided inside the chassis 1 for placing electrical components, four guide rods 20 are provided on the bottom wall of the chassis 1, springs 19 are sleeved on the guide rods 20, guide holes are provided on the support plate 18 at positions corresponding to the guide rods 20, the guide rods 20 pass through the guide holes, and a stop plate 21 is provided at the upper end of the guide rods 20 to prevent the support plate 18 from being separated from the guide rods 20. The arrangement of the guide rods 20 and the springs 19 can play a role in shock absorption and buffering for the support plate 18.

[0035] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention.
