[0002] Vehicle-mounted power take-off power generation refers to a technology that uses the engine speed of a vehicle to drive a generator to generate electricity. This power generation method is widely used in special vehicles such as command vehicles, communication vehicles, fire trucks, police cars, etc. to provide stable power support for the electronic devices on these vehicles.

[0003] Currently, the existing vehicle-mounted power take-off power generation mechanisms still have the following deficiencies: 1. When the power take-off generator is damaged, it is necessary to repair the power take-off generator immediately and cannot repair the power take-off generator after the emergency task is completed, which affects the progress of emergency task handling; 2. When the power take-off generator has a high temperature during operation, it cannot assist the power take-off generator in heat dissipation, resulting in the power take-off generator being in a high-temperature state for a long time; 3. When the temperature of the power take-off generator is higher than the dangerous temperature value due to a short circuit or other faults, it cannot automatically isolate the power take-off generator from external oxygen, resulting in the power take-off generator being prone to spontaneous combustion. Moreover, when a slight spontaneous combustion occurs, it cannot automatically extinguish, posing a safety hazard. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the power take-off generator below of the present invention is damaged, the staff can switch the standby power take-off generator above to below for use through the switching handle, ensuring normal power generation effect. When the power take-off generator is damaged, the staff does not need to go to the maintenance site to repair the power take-off generator immediately, which is convenient for the staff to handle the current urgent task first and then repair the power take-off generator after the urgent task is completed, without affecting the progress of handling the urgent task. When the staff switches the power take-off generator through the switching handle, the two movable tension rods can automatically move outwards under the action of the four helical springs A, keeping the transmission belt always in a tightened state, which is beneficial to the accurate connection between the switched power take-off generator and the transmission belt. When the switching of the power take-off generator is completed, the transmission belt can drive the two movable tension rods to reset inwards.

[0016] 2. The setting of the octagonal pin of the present invention plays a positioning role for the rotated rotary mounting seat, making the power take-off generator more stable after switching. When the rotary mounting seat rotates half a turn, the trigger bar can automatically press the control button. When the control button is in the pressed state, the buzzer inside the intelligent controller alarms intermittently, which can intermittently remind the staff to repair the power take-off generator, so that when the staff returns after the urgent task is completed, they can remember the damaged power take-off generator, which is beneficial to timely repair the damaged power take-off generator after the urgent task is completed, and still has the standby power generation effect for the next use.

[0017] 3. When the temperature sensor below detects that the temperature of the power take-off generator is more than ten degrees higher than the normal temperature value, the intelligent controller controls the micro-motor to work, making the two arc-shaped sealing covers move inwards at the same time. When the two arc-shaped sealing covers contact, the intelligent controller controls the micro-motor to stop working. At the same time, the intelligent controller controls the two auxiliary fans to work. When the two auxiliary fans work, external air enters the two arc-shaped sealing covers and then is discharged from the two arc-shaped sealing covers, accelerating the air flow speed at the power take-off generator, playing an auxiliary heat dissipation effect and preventing the power take-off generator from being in a high temperature state for a long time. When the temperature sensor below detects that the temperature of the power take-off generator is lower than the normal temperature value, the intelligent controller controls the two auxiliary fans to stop working. At the same time, the intelligent controller controls the micro-motor to work, making the two arc-shaped sealing covers move outwards at the same time. When the two arc-shaped sealing covers move to the specified position, the intelligent controller controls the micro-motor to stop working; In addition, when the temperature sensor below detects that the temperature of the auxiliary heat dissipation power take-off generator is higher than the dangerous temperature value, the intelligent controller controls the two auxiliary fans to stop working, and the intelligent controller disconnects the power supply of the two electromagnets. When the two electromagnets are in a power-off state, the two movable sealing plates automatically move downward under their own gravity, so that the holes on the two movable sealing plates are misaligned with the holes on the two arc-shaped sealing covers and the two exhaust flat plates, ensuring that the power take-off generator below is in a sealed environment, realizing automatic isolation from external oxygen, and avoiding spontaneous combustion of the power take-off generator in case of short circuit or other failures. When a slight spontaneous combustion occurs in the power take-off generator, the flame is always in the two arc-shaped sealing covers. When the oxygen in the two arc-shaped sealing covers is consumed, the flame automatically goes out, with relatively low potential safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

When the two arc-shaped sealing covers 5032 move to the specified position, the intelligent controller 300 controls the micro motor 501 to stop working;When the temperature sensor 204 below detects that the temperature of the auxiliary heat dissipation power take-off generator 203 is higher than the dangerous temperature value, the intelligent controller 300 controls the two auxiliary fans 5033 to stop working, and the intelligent controller 300 disconnects the power supplies of the two electromagnets 5037; when the two electromagnets 5037 are in the power-off state, the two movable sealing plates 5036 automatically move downward under their own gravity, so that the holes on the two movable sealing plates 5036 are misaligned with the holes on the two arc-shaped sealing covers 5032 and the two exhaust flat plates 5034, ensuring that the power take-off generator 203 below is in a sealed environment, realizing automatic isolation from external oxygen, and avoiding spontaneous combustion of the power take-off generator 203 in case of short circuit or other failures; when the power take-off generator 203 has a slight spontaneous combustion situation, the flames are always in the two arc-shaped sealing covers 5032, and the potential safety hazard is relatively low.
