Description

Technical Field

[0001] This invention relates to the field of power cabinet technology, and more specifically, to an automatic temperature control device for power cabinets. Background Technology

[0002] A power cabinet is a cabinet in which electronic components work together. It usually has related integrated functions and is built in various places, both outdoors and indoors. Outdoor power cabinets often have ventilation holes on their surface to dissipate heat in order to adapt to the external environment. However, the temperature of the external environment is constantly changing. In addition to the temperature changes of the four seasons, there are also certain differences in the temperature between day and night in some places. Therefore, in order to adapt to heat dissipation under high heat conditions, although the fans can accelerate the heat dissipation efficiency, they will continue to run after the temperature drops. Long-term operation and the inability to automatically regulate will only aggravate energy consumption. Although it can ensure the normal operation of the power cabinet, it undoubtedly increases the overall heat dissipation cost.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] As attached Figure 1-7 The device shown is an automatic temperature control device for a power distribution cabinet, including a power distribution cabinet body 1. A cabinet door 2 is rotatably installed on the front of the power distribution cabinet body 1. A scanning and inspection mechanism 3 is movably installed at the upper end of the power distribution cabinet body 1. An opening and closing device 5 is movably installed at the bottom end of the power distribution cabinet body 1. A temperature control device 4 is fixedly installed inside the power distribution cabinet body 1.

[0029] Among them, as attached Figure 3 and attached Figure 4The distribution cabinet 1 has a vertical groove 11 on its inner wall, a first limiting ring 12 fixedly installed inside the distribution cabinet 1, a second limiting ring 13 fixedly installed inside the distribution cabinet 1, circular grooves 14 on both the left and right sides of the inner wall of the distribution cabinet 1, a horizontal groove 15 in the middle of the inner wall of the distribution cabinet 1, through holes 16 on the surface of the distribution cabinet 1, and heat dissipation grooves 17 at both the left and right ends of the distribution cabinet 1. The scanning and inspection mechanism 3 includes a mounting plate 31, a first motor 32 fixedly installed at the top of the mounting plate 31, a sleeve 33 fixedly connected to the output shaft of the first motor 32, a stud 34 fixedly installed at the top of the sleeve 33, and a transmission plate 35 threaded onto the surface of the stud 34. A limiting plate 36 is fixedly installed on the back of plate 35. A second motor 37 is fixedly installed at the bottom of the mounting plate 31. A gear 38 is fixedly sleeved on the output shaft of the second motor 37. The limiting plate 36 is slidably installed inside the vertical groove 11. A temperature sensor is fixedly installed on the front of the transmission plate 35. The sleeve 33 is rotatably installed on the surface of the first limiting ring 12. The back of the mounting plate 31 is fixedly installed on the inner wall of the power distribution cabinet 1. The gear 38 is rotatably installed inside the second limiting ring 13. The temperature sensor and the second motor 37 are electrically connected to each other. The rotation of the second motor 37 is controlled by the electrical connection between the temperature sensor and the second motor 37, thereby realizing the purpose of opening or closing the movable partition 54 and achieving automated control of the device.

[0030] Among them, as attached Figure 5 The temperature control device 4 includes a ventilation pipe 41. An air inlet device 42 is fixedly installed at one end of the ventilation pipe 41, and a four-way box 43 is fixedly installed at one end of the air inlet device 42. A circular electric heating resistance wire mesh 44 is fixedly installed inside the four-way box 43. A control terminal 45 is fixedly installed at the top of the four-way box 43. Ventilation boxes 46 are fixedly connected to both the left and right sides of the four-way box 43. A socket frame 47 is fixedly installed at the bottom of the ventilation box 46. The control terminal 45 is electrically connected to the air inlet device 42 and the four-way box 43 respectively. The four-way box 43 is electrically connected to a temperature sensor. The surface of the ventilation pipe 41 is fixedly installed inside the through hole 16. The temperature sensor is used to control the control terminal 45, which further controls whether the circular electric heating resistance wire mesh 44 is working, thereby determining whether the internal heating and heat preservation or heat dissipation is performed, thus improving the applicability of the overall device.

[0031] Among them, as attached Figure 6 To be continued Figure 7The opening and closing device 5 includes a double-threaded screw 51, with rotation limiting posts 52 fixedly installed at both ends of the double-threaded screw 51. A gear 53 is integrally formed in the middle of the double-threaded screw 51. A movable sealing plate 54 is threadedly installed on the surface of the rotation limiting post 52. The surface of the gear 53 meshes with the bottom end of the gear disk 38. Both ends of the double-threaded screw 51 are rotatably installed in the circular groove 14 via the rotation limiting posts 52. The movable sealing plate 54 includes a sealing isolation plate 541, with the back of the sealing isolation plate 541 fixed. A transmission straight plate 542 is installed. A sleeved load-bearing plate 543 is fixedly installed on the left side of the sealed isolation plate 541. A first ventilation groove 544 is opened on the upper side of the sealed isolation plate 541, and a second ventilation groove 545 is opened on the lower side of the sealed isolation plate 541. Vertical connecting grooves 546 are opened inside both the second ventilation groove 545 and the first ventilation groove 544. An isolation protrusion 547 is fixedly installed on the right side surface of the sealed isolation plate 541. A third ventilation groove 548 is opened on both the upper and lower surfaces of the isolation protrusion 547. The back of the transmission straight plate 542... The end is slidably installed inside the transverse groove 15. The transmission straight plate 542 slides inside the transverse groove 15, ensuring that the movable sealing plate 54 can only move in one axis when driven by the rotation of the double-threaded screw 51, preventing rotational deviation. Its entire assembly is threaded onto the surface of the double-threaded screw 51. The sleeve-supporting plate 543 is movably sleeved inside the sleeve frame 47. The sleeve-supporting plate 543 sleeved inside the sleeve frame 47 provides support for its movement, preventing the entire assembly from falling due to its weight and ensuring normal operation. (Second ventilation...) The slot 545 and the third ventilation slot 548 are interconnected. The interconnection between the third ventilation slot 548 and the second ventilation slot 545 allows the sealed isolation plate 541 to quickly ventilate and dissipate heat when leaving the interior of the heat dissipation slot 17. The vertical connecting slot 546 is shaped as a combination of an isosceles trapezoidal block and a rectangular block. The rectangular block allows the space to gradually expand when it is pushed out, thereby achieving the effect of ventilation. The rectangular block is also used for sealing purposes, which largely isolates the interior of the power distribution cabinet 1 from the exterior.

[0032] The working principle of this invention is as follows: the first motor 32 drives the stud 34 to rotate, which causes the transmission plate 35 to move up and down, thereby driving the temperature sensor at its positive end to monitor the internal temperature. When the temperature is too high or the internal temperature is too low, which are both outside the threshold range initially set by the temperature sensor, different responses and adjustments will be made respectively.

[0033] When the temperature is too low, the temperature sensor converts the temperature signal into an electrical signal and transmits it to the inside of the control terminal 45. The control terminal 45 energizes the coiled electric heating wire mesh 44 and the air intake device 42 to blow air. After being heated by the coiled electric heating wire mesh 44, the airflow enters the inside of the distribution cabinet 1. The airflow quickly raises the internal temperature of the distribution cabinet 1, ensuring that the internal temperature enters the set threshold.

[0034] When the temperature is too high, the temperature sensor transmits the signal to the inside of the second motor 37, which then drives the gear 38 to rotate, causing the gear 53 to rotate. This, in conjunction with the transmission straight plate 542, moves the sealed isolation plate 541 towards each other, and the isolation protrusion 547 is pulled out from the inside of the heat dissipation slot 17. At this time, the heat dissipation slot 17 is connected to the second ventilation slot 545 through the third ventilation slot 548, and further connected to the first ventilation slot 544 through the vertical connecting slot 546. At this time, the air intake device 42 also blows air, but the circular electric heating wire mesh 44 does not generate electricity for heating. The inside and outside of the distribution cabinet 1 are circulated, the airflow speed is increased, and the heat is transported more quickly, so that the inside can be physically cooled.

[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
