Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, specifically to an HVAC electrical control cabinet for HVAC engineering. Background Technology

[0002] HVAC electrical control cabinets for HVAC engineering control various electrical equipment in the HVAC system to start, stop, and adjust speed, ensuring that the equipment operates according to the predetermined requirements. The start and stop of the equipment can be directly controlled by manual operating elements such as buttons and knobs on the control cabinet panel, which is convenient for on-site commissioning and operation in emergency situations.

[0003] The existing technology has the following problems:

[0004] The existing device cannot clean the surface of the dustproof panel when cooling the inside of the cabinet. The dust accumulation on the surface of the dustproof panel will form a heat insulation layer, which will prevent outside air from entering the refrigeration box through the dustproof panel. This will reduce heat dissipation efficiency, especially when there is refrigeration equipment running inside the electrical control cabinet. In addition, the existing device cannot clamp and fix the controller's wires. If the controller's wires are not fixed, they may become loose or fall off during the operation of the electrical control cabinet due to vibration, equipment start-up and shutdown, or external interference. Loose wires may cause signal transmission interruption, and the controller will not be able to receive sensor signals or send control commands normally. Utility Model Content

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 As shown, this utility model provides a heating, ventilation, and air conditioning (HVAC) electrical control cabinet for HVAC engineering, including a cabinet body 1, a cabinet door 2 hinged to the cabinet body 1, a fan 3 fixedly connected to the left side of the cabinet body 1, a refrigeration box 4 fixedly connected to the left side of the cabinet body 1, an air inlet pipe assembly 5 fixedly connected to the left side of the refrigeration box 4, an output pipe of the fan 3 fixedly connected to the cabinet body 1, and a connecting pipe 23 fixedly connected to the upper side of the refrigeration box 4. The other end of the connecting pipe 23 is fixedly connected to the input end of the fan 3. When the HVAC electrical control cabinet is running, the fan 3 starts, draws air out of the refrigeration box 4 through the connecting pipe 23, and sends it into the cabinet body 1 through the output pipe for cooling, thereby cooling the inside of the cabinet body 1. External air enters the refrigeration box 4 through the air inlet pipe assembly 5, providing a fresh air source for the cooling process.

[0023] like Figure 2As shown, a dustproof plate 24 is fixedly connected to the inner surface of the air intake pipe assembly 5. Two connecting plates 6 are fixedly connected to the left side of the air intake pipe assembly 5. A first motor 7 is fixedly connected to the left side of the connecting plate 6. A drive wheel 8 is fixedly connected to the output shaft of the first motor 7. A synchronous belt 11 is driven to the outer wall of the drive wheel 8. A driven wheel 12 is movably connected to the inner surface of the synchronous belt 11. A driven shaft 10 is fixedly connected through the left side of the driven wheel 12. The outer wall of the driven shaft 10 is rotatably connected to the connecting plate 6. A rotating disk 9 is fixedly connected to the right end of both the driven wheel 12 and the output shaft of the first motor 7. Multiple cleaning plates 2 are fixedly connected to the right side of the rotating disk 9. 5. The cleaning surface of the cleaning plate 25 is movably connected to the dustproof plate 24. When the first motor 7 starts, its output shaft drives the drive wheel 8 to rotate. The drive wheel 8 drives the driven wheel 12 to rotate synchronously through the synchronous belt 11. The driven wheel 12 and the rotating disk 9 at the right end of the output shaft of the first motor 7 rotate accordingly. The cleaning plate 25 fixed on the rotating disk 9 will continuously contact the dustproof plate 24 and clean its surface during the rotation. In this way, the dust accumulated on the surface of the dustproof plate 24 is cleaned away, reducing the ventilation resistance of the air intake pipe assembly 5, so that the outside air can enter the refrigeration box 4 more smoothly, thereby improving the refrigeration efficiency of the entire device.

[0024] like Figure 3-5 As shown, this utility model provides a technical solution: Preferably, a control device body 13 is fixedly connected to the inner surface of the cabinet 1, a support plate 14 is fixedly connected to the right side of the inner surface of the cabinet 1, a second motor 15 is fixedly connected to the upper side of the support plate 14, a rotating block 19 is fixedly connected to the output shaft of the second motor 15, two guide posts 20 are fixedly connected to the lower side of the rotating block 19, a fixed clamping plate 26 is fixedly connected to the inner surface of the cabinet 1, multiple wires 16 are movably connected to the front side of the fixed clamping plate 26, two limiting plates 18 are fixedly connected to the front side of the fixed clamping plate 26, a movable clamping plate 17 is slidably connected to the outer wall of the limiting plate 18, the outer wall of the wires 16 is movably connected to the movable clamping plate 17, and the upper part of the fixed clamping plate 26 and the movable clamping plate 17 are connected to each other. Two sliding grooves 27 are provided on each side. The outer wall of the guide post 20 is slidably connected to the sliding groove 27. After the second motor 15 is started, its output shaft drives the rotating block 19 to rotate. The guide post 20 on the lower side of the rotating block 19 slides in the sliding groove 27 opened on the upper side of the fixed clamping plate 26 and the movable clamping plate 17. As the guide post 20 slides, the movable clamping plate 17 moves along the direction of the limiting plate 18 under the constraint of the limiting plate 18, thereby realizing the clamping and releasing of the wire 16. In this way, the wire 16 of the controller is firmly clamped between the fixed clamping plate 26 and the movable clamping plate 17, so that the wire 16 will not loosen or fall off due to vibration, equipment start-up and shutdown or external interference during the operation of the electrical control cabinet, ensuring that the device can operate stably and normally.

[0025] The working principle of the HVAC electrical control cabinet used in this HVAC project will be explained in detail below.

[0026] like Figure 1-5 As shown, when the HVAC control cabinet is running, the fan 3 starts, drawing air from the refrigeration box 4 through the connecting pipe 23 and sending it into the cabinet 1 through the output pipe for cooling, thus lowering the temperature inside the cabinet 1. External air enters the refrigeration box 4 through the intake pipe assembly 5, providing fresh air for the cooling process. When the first motor 7 starts, its output shaft drives the drive wheel 8 to rotate. The drive wheel 8 drives the driven wheel 12 to rotate synchronously via the synchronous belt 11. The driven wheel 12 and the rotating disk 9 at the right end of the output shaft of the first motor 7 rotate accordingly. The cleaning plate 25 fixed on the rotating disk 9 continuously contacts the dustproof plate 24 during rotation, cleaning its surface. In this way, the dust accumulated on the surface of the dustproof plate 24 is removed, reducing the impact on the intake pipe assembly 5. The ventilation resistance allows outside air to enter the refrigeration box 4 more smoothly, thereby improving the refrigeration efficiency of the entire device. After the second motor 15 starts, its output shaft drives the rotating block 19 to rotate. The guide post 20 on the lower side of the rotating block 19 slides in the groove 27 opened on the upper side of the fixed clamping plate 26 and the movable clamping plate 17. As the guide post 20 slides, the movable clamping plate 17 moves along the direction of the limiting plate 18 under the constraint of the limiting plate 18, thereby realizing the clamping and releasing of the wire 16. In this way, the wire 16 of the controller is firmly clamped between the fixed clamping plate 26 and the movable clamping plate 17, so that the wire 16 will not loosen or fall off due to vibration, equipment start-up and shutdown or external interference during the operation of the electrical control cabinet, ensuring that the device can operate stably and normally.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
