Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with sensor ventilation. Background Art

[0002] Distribution cabinets (boxes) are classified as power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final stage of the power distribution system. A distribution cabinet is a general term for motor control centers (MCCs). Distribution cabinets are suitable for applications with relatively dispersed loads and a small number of circuits, while MCCs are used in applications with concentrated loads and a large number of circuits. They distribute power from a circuit in the upper-level distribution equipment to the nearest load. This type of equipment provides load protection, monitoring, and control. With technological advancements, distribution cabinets have become increasingly versatile, making them safer to use.

[0003] In response to this, Chinese patent number CN217741002U proposes a technical field for distribution cabinet equipment. The utility model has the advantages of excellent heat dissipation, intelligent adjustment of ventilation hole opening, and dust and moisture removal. However, the above technical solution and the existing distribution cabinet are in the case of sensor-type heat dissipation and ventilation. When encountering heavy rain, if the sensor-type ventilation function is turned on, it is impossible to block the outside rainwater, which may easily cause rainwater to penetrate into the distribution cabinet and cause internal circuit short circuit, causing damage to components in the distribution cabinet. Maintaining the rainproof function all the time will affect the opening and closing degree of the ventilation area and affect the ventilation effect. Therefore, a sensor-type rainproof structure is needed. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a distribution cabinet with sensor ventilation to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a power distribution cabinet with sensor ventilation, comprising a power distribution cabinet body, wherein a sensor-type rainproof mechanism is provided on the upper end of the power distribution cabinet body;

[0006] The sensing rainproof mechanism includes a plurality of through slots equidistantly provided on both sides of the outer wall of the distribution cabinet body, and protective plates are rotatably provided on both sides of the distribution cabinet body at the edge of each through slot. A first motor is fixed on both sides of the top of the distribution cabinet body, and a worm gear is fixed at one end of each protective plate, and one end of each worm gear is rotatably connected to the inner wall of the distribution cabinet body. Worms are rotatably provided on the inner walls of the two ends of the distribution cabinet body, and the outer walls of the two worms are respectively engaged with the outer walls of the plurality of worm gears. Pressure sensors are fixed at the two corners of the top of the distribution cabinet body, and the two first motors are electrically connected to the two pressure sensors. A water storage tray is interspersed at the upper end of the two pressure sensors at the top of the distribution cabinet body.

[0007] In one example, springs are sleeved on the four corners of the bottom of the two water storage trays, and one end of each spring is fixedly connected to the top of the distribution cabinet body, and a through hole is opened on one side of the two water storage trays.

[0008] In one example, one end of the two worms is fixedly connected to the output ends of the two first motors respectively, and a dustproof net is fixedly provided on the inner wall of each through slot.

[0009] In one example, support frames are fixed on both sides of the inner wall of the distribution cabinet body, and limiting grooves are opened on both sides of the two support frames. Multiple sealing plates are slidably provided between the inner walls of the four limiting grooves, and two racks are fixed on one side of each sealing plate.

[0010] In one example, gears are rotatably provided at the edges on both sides of the inner wall of the distribution cabinet body, and the outer walls of the two gears are respectively engaged with the outer walls of the two racks, and temperature sensors are fixed at the upper ends of the two gears on both sides of the inner wall of the distribution cabinet body.

[0011] In one example, second motors are fixedly provided at the edges of both sides of the outer wall of the power distribution cabinet body, and the two second motors are electrically connected to the two temperature sensors.

[0012] In one example, one end of the two gears passes through the inner wall of the power distribution cabinet body and is fixedly connected to the output ends of the two second motors, and a protective cabinet door is hingedly provided on one side of the power distribution cabinet body.

[0013] The power distribution cabinet with sensor ventilation proposed by the utility model can bring the following beneficial effects:

[0014] 1. When the distribution cabinet with sensor ventilation encounters heavy rain, the water storage pan on the upper end of the distribution cabinet body will carry rainwater. When the load reaches a certain amount, it will squeeze the pressure sensor at the lower end to start the first motor, and then rotate the worm to rotate the worm wheel, and turn the protective plate down to make it more inclined to protect the upper end of the through slot, so that rainwater is not easy to enter the through slot. After the rain stops, the through holes in the water storage pan gradually drain the rainwater. Under the elastic action of the spring, the water storage pan rises without contacting the pressure sensor, and the first motor can be reversely driven to make the worm engage the worm wheel in reverse and then rotate the protective plate to a horizontal position, so that the through slot opens at a larger angle, which is more convenient for heat dissipation and improves the safety of the device.

[0015] 2. In the distribution cabinet with sensor ventilation, when the components in the distribution cabinet are operating normally, the internal temperature rises, and the temperature sensor gives a command to start the second motor to rotate the gear to engage the rack. The rack slides in the limiting slide with the sealing plate, thereby blocking or opening the through slot on one side, so that it can dissipate heat or be closed, thereby achieving the purpose of sensor ventilation. There is no need for staff to pay attention to internal temperature changes at all times, thereby improving the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0024] The examples are as follows:

[0025] The utility model provides Figure 1-5 The power distribution cabinet with sensor ventilation shown includes a power distribution cabinet body 1, and a sensor rainproof mechanism is provided on the upper end of the power distribution cabinet body 1;

[0026] The sensing rainproof mechanism includes a plurality of through slots 2 equidistantly provided on both sides of the outer wall of the distribution cabinet body 1. Protective plates 3 are rotatably provided on the edges of each through slot 2 on both sides of the distribution cabinet body 1. A first motor 4 is fixed on both sides of the top of the distribution cabinet body 1. A worm gear 5 is fixed at one end of each protective plate 3, and one end of each worm gear 5 is rotatably connected to the inner wall of the distribution cabinet body 1. Worms 6 are rotatably provided on the inner walls of the two ends of the distribution cabinet body 1, and the outer walls of the two worm gears 6 are respectively engaged with the outer walls of the plurality of worm gears 5. Pressure sensors 7 are fixed at the two corners of the top of the distribution cabinet body 1, and the two first motors 4 are electrically connected to the two pressure sensors 7. A water storage tray 8 is interspersed at the upper ends of the two pressure sensors 7 at the top of the distribution cabinet body 1.

[0027] Springs 9 are sleeved on the four corners of the bottom of the two water storage trays 8, and one end of each spring 9 is fixedly connected to the top of the distribution cabinet body 1. A through hole 10 is opened on one side of the two water storage trays 8, and the through holes 10 at the upper ends of the two water storage trays 8 have a slow drainage speed. When the rainfall is large, the drainage speed is lower than the water storage speed. Therefore, the protective plate 3 always maintains a tilted protective state. After the rainfall stops, the through holes 10 drain the rainwater in the water storage tray 8. After that, the protective plate 3 is meshed with the worm gear 5 and the worm 6 so that it is in a 90-degree state with the through slot 2 to achieve maximum ventilation effect;

[0028] Furthermore, one end of the two worms 6 is fixedly connected to the output ends of the two first motors 4, respectively. A dustproof net 11 is fixedly provided on the inner wall of each through slot 2, and the dustproof net 11 plays a dustproof effect during ventilation.

[0029] Furthermore, support frames 12 are fixed on both sides of the inner wall of the distribution cabinet body 1, and limiting grooves 13 are opened on both sides of the two support frames 12. Multiple sealing plates 14 are slidably provided between the inner walls of the four limiting grooves 13, and two racks 15 are fixed on one side of each sealing plate 14.

[0030] Gears 16 are rotatably provided at the edges of both sides of the inner wall of the distribution cabinet body 1, and the outer walls of the two gears 16 are respectively engaged with the outer walls of the two racks 15. Temperature sensors 17 are fixed on the upper ends of the two gears 16 on both sides of the inner wall of the distribution cabinet body 1. The two racks 15 are respectively connected to the sealing plates 14 at the upper ends of the corresponding support frames 12. When the racks 15 are engaged and move up and down, the sealing plates 14 also move up and down together to seal or open the through slots 2.

[0031] Furthermore, second motors 18 are fixedly provided at the edges of both sides of the outer wall of the power distribution cabinet body 1 , and the two second motors 18 are electrically connected to the two temperature sensors 17 .

[0032] One end of the two gears 16 passes through the inner wall of the distribution cabinet body 1 and is fixedly connected to the output ends of the two second motors 18. A protective cabinet door 19 is hingedly provided on one side of the distribution cabinet body 1, and protective shells are provided on the outside of the two first motors 4 and the two second motors 18 to protect them.

[0033] Working principle: When using the distribution cabinet with sensor ventilation in this design, you first need to rotate the protective plate 3 at the upper end of the device and install it on both sides of the distribution cabinet body 1, so that each of them is located at the upper edge of the through slot 2. At the same time, each protective plate 3 is fixedly connected to one side of the worm gear 5 that is rotatably connected to the inner wall of the distribution cabinet body 1. When using the distribution cabinet, when the internal temperature sensor 17 senses that the internal temperature has risen, the second motor 18 is started to move the sealing plate 14 to open the through slot 2 for heat dissipation. At this time, when heavy rain occurs, the water storage tray 8 at the upper end of the distribution cabinet body 1 will carry rainwater. When the load reaches a certain amount, it will squeeze the pressure sensor 7 at the lower end to start the first motor 4, and then rotate the worm 6 to rotate the worm gear 5, and turn the protective plate 3 down, so that it is more inclined to protect the upper end of the through slot 2, and rainwater is not easy to enter the through slot 2. In the middle, the rainfall stops, and the through hole 10 in the water storage tray 8 gradually drains the rainwater. Under the elastic action of the spring 9, the water storage tray 8 rises without contacting the pressure sensor 7, and the first motor 4 can be driven in reverse to make the worm 6 reversely mesh with the worm gear 5, and then the protective plate 3 is rotated to the horizontal, so that the through slot 2 opens at a larger angle, which is more convenient for heat dissipation and improves the safety of the device. When the components in the distribution cabinet are operating normally, the internal temperature rises, and the temperature sensor 17 gives an instruction to start the second motor 18 to make the gear 16 rotate and mesh with the rack 15. The rack 15 slides with the sealing plate 14 in the limiting slide 13 and then blocks or opens the through slot 2 on one side, so that it can dissipate heat or be closed, thereby achieving the purpose of sensor-type ventilation. There is no need for staff to pay attention to internal temperature changes at all times, thereby improving the convenience of using the device.
