DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Embodiment 1
[0032] See also Figure 1-13 The utility model provides a technical solution: a fan control cabinet with multiple protection functions, including a fan control cabinet body 1, a control cabinet shell 11 is arranged on the periphery of the fan control cabinet body 1, and a ventilation port 12 is arranged on the rear side of the control cabinet shell 11; a closure 2, the closure 2 is located on one side of the ventilation port 12, and the closure 2 can close the ventilation port 12; a trigger mechanism 3, the trigger mechanism 3 is located inside the control cabinet shell 11, and the trigger mechanism 3 can trigger the closure 2 through the temperature change inside and outside the fan control cabinet body 1. When the new type is in use, when there is a short circuit in the wires, a failure of electrical equipment, an overload, etc. inside or outside the fan control cabinet body 1 and a fire is caused, the fan control cabinet body 1 can trigger the trigger mechanism 3 according to the temperature change inside and outside the control cabinet shell 11. The trigger mechanism 3 closes the switch by cutting off the ventilation port 12, thereby isolating the control cabinet body from the outside air. The external fire will not enter the interior of the control cabinet body through the ventilation port 12. The internal fire will be extinguished due to the low oxygen content. At the same time, the buzzer 72 will be triggered to remind the staff to carry out rescue and maintenance, which is safer when in use.
[0033] The trigger mechanism 3 includes a through slot 31 opened on one side of the control cabinet housing 11, a telescopic cylinder 32 is fixedly connected to the inner wall of the through slot 31, a telescopic rod 33 is slidably connected inside the telescopic cylinder 32, a spring 34 is fixedly connected below the telescopic rod 33, an end of the spring 34 away from the telescopic rod 33 is fixedly connected to a fixing block 35, a thermosensitive glass tube 36 is fixedly connected below the telescopic rod 33, an end of the thermosensitive glass tube 36 away from the telescopic rod 33 is fixedly connected to the fixing block 35, and the thermosensitive glass tube 36 is located in the center of the spring 34. At this time, the reset spring 34 is compressed. When a short circuit, electrical equipment failure, overload, etc. occur inside and outside the fan control cabinet body 1 and a fire is caused, the temperature rises, the thermosensitive glass tube 36 is broken, and the telescopic rod 33 no longer pulls the fixing block 35. At this time, the reset spring 34 is reset, and the spring 34 pushes the fixing block 35 downward, which paves the way for triggering the trigger member 4.
[0034] A triggering member 4 capable of triggering the closing member 2 is provided below the fixed block 35, and the triggering member 4 includes a slider 41 provided below the fixed block 35, the slider 41 is not fixedly connected to the fixed block 35, and both ends of the slider 41 are fixedly connected to limiting blocks 42, and limiting grooves 43 are provided on both sides of the through groove 31, and the limiting blocks 42 are located inside the limiting grooves 43 and are slidably connected to the limiting grooves 43, and a blade 44 is fixedly connected below the slider 41, and a knife groove 45 is fixedly connected to the inner wall of the through groove 31, and the knife groove 45 is located below the blade 44, and a soft pad 46 is fixedly connected to the inner wall of the limiting groove 43, and the soft pad 46 carries the slider 41, and the knife groove 45 is V-shaped, and the wire 5 is carried above the knife groove 45.
[0035] When the fixed block 35 is pushed downward, the fixed block 35 abuts against the slider 41 and pushes the slider 41. The limit blocks 42 on both sides of the slider 41 pass over the soft pads 46. The limit blocks 42 slide in the limit grooves 43. The slider 41 is pushed by the fixed block 35 due to its inertia and its own gravity potential energy. The blade 44 is inserted into the knife groove 45 and cuts off the wire 5. Since the knife groove 45 is V-shaped, the knife groove 45 can prevent the blade 44 from slipping off when cutting the wire 5. Before the thermal glass tube 36 is broken, the soft pads 46 support the slider 41 and fix it. The block 35 compresses the spring 34 above the slider 41, and the spring 34 lifts the telescopic rod 33 and pushes the telescopic rod 33 into the telescopic tube 32. After the thermosensitive glass tube 36 is broken, the slider 41 no longer lifts the telescopic rod 33 through the fixed block 35, and the telescopic rod 33 slides in the telescopic tube 32. The telescopic rod 33 fills the original position of the thermosensitive glass tube 36, which prevents the fire from spreading from the inside to the outside or from the outside to the inside, and on the other hand, closes the position of the thermosensitive glass tube 36, so that the fire inside the fan control cabinet body 1 is automatically extinguished due to lack of oxygen.
[0036] The closing member 2 includes an electromagnet 21 fixedly connected inside the control cabinet housing 11, the electromagnet 21 is located on one side of the ventilation port 12, the electromagnet 21 is slidably connected to the side away from the control cabinet housing 11 with an electromagnet 22, one side of the electromagnet 22 is fixedly connected to a closing plate 23, the inner wall of the control cabinet housing 11 is fixedly connected to a limiting plate 24, the closing plate 23 is located inside the limiting plate 24 and slidably connected to the limiting plate 24, the electromagnet 21 is connected to the wire 5, after the power is cut off, the electromagnet 21 is powered off, the electromagnet 21 no longer attracts the electromagnet 22, the electromagnet 22 and the closing plate 23 fall due to their own gravity, the closing plate 23 closes the ventilation port 12 to prevent the fire from spreading, and it is very safe to use.
[0037] Embodiment 2
[0038] Paraffin 6 is fixedly connected to the bottom of the telescopic rod 33. The end of the paraffin 6 away from the telescopic rod 33 is fixedly connected to the fixed block 35. The paraffin 6 is located in the center of the spring 34. After the paraffin 6 melts, the paraffin 6 drips on the cut wire 5. Since the paraffin 6 is an insulating material, the dripping paraffin 6 can seal the cut wire 5, which is safer when used.
[0039] Embodiment 3
[0040] A switching button 7 is fixedly connected to the inner wall of the through groove 31, a trigger rod 71 is fixedly connected under the slider 41, the electromagnet 21 is connected to the switching button 7 through a wire 5, and a buzzer 72 is fixedly connected to the outer wall of the control cabinet housing 11, and the buzzer 72 is connected to the switching button 7 through a wire 5. When the spring 34 is reset, the spring 34 pushes the slider 41 through the fixed block 35, and the trigger rod 71 under the slider 41 presses the switching button 7 to switch the power supply of the electromagnet 21 to the buzzer 72. At this time, the buzzer 72 works, which on the one hand reminds the staff that the fan control cabinet body 1 is working in an environment with too high temperature, so as to avoid the fan control cabinet body 1 working at high temperature for a long time, thereby causing damage to the internal electrical components of the fan control cabinet body 1; on the other hand, a fire occurs inside or outside the fan control cabinet body 1, reminding the staff to rescue or evacuate.
