Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.
[0020] The following will be combined with the instructions Figure 1-3 The above technical solutions are described in detail with specific implementation methods:
[0021] The utility model provides a generator body 1 overheating protection device, including a base plate 2 and a generator body 1, a bracket 4 is fixedly connected to the base plate 2, and a mounting plate 3 is detachably fixedly connected to the bottom of the generator body 1, and the mounting plate 3 can slide on the base plate 2 and enter the bracket 4. After entering the bracket 4, the mounting plate 3 is fixedly connected to the bracket 4 through a fixed structure. A temperature detection unit, a control unit and a cooling unit are provided on the bracket 4. The temperature detection unit is used to detect the temperature of the generator body 1 and transmit the temperature signal to the control unit. The control unit controls the working state of the cooling unit according to the temperature signal.
[0022] In actual application, the bracket 4 is made of sturdy metal material and is fixed to the base plate 2 by welding or bolting to ensure its stability and firmness. The shape and size of the bracket 4 can be designed according to the appearance of the generator body 1 so that it can completely wrap the generator body 1, and then the generator body 1 is fixed on the mounting plate 3. The mounting plate 3 is made of high-strength alloy material and the surface is smoothed to reduce friction. The mounting plate 3 can be connected to the base plate 2 through a slide rail so that it can slide smoothly into the bracket 4, so that the generator body 1 can enter the bracket 4 along with the mounting plate 3. When the mounting plate 3 enters the bracket 4, the fixing structure will fix the mounting plate 3 to the bracket 4, so that the generator body 1 can have a stable working environment. The temperature detection unit, control unit and cooling unit are installed around the generator body 1 through the bracket 4 according to the predetermined position to realize the overheating protection function of the generator.
[0023] As a preferred embodiment, the temperature detection unit includes multiple temperature sensors 5, which are distributed around the generator body 1 at different locations on the bracket 4. Temperature sensors 5 are mounted on the bracket 4 at locations corresponding to key parts of the generator body 1, such as the cylinder block, exhaust pipe, and oil tank, to ensure comprehensive detection of temperature changes in all key parts of the generator body 1. Each temperature sensor 5 is connected to the control unit via a dedicated line to ensure accurate transmission of temperature signals.
[0024] In a preferred embodiment, the temperature sensor 5 is a thermocouple temperature sensor or a thermal resistor temperature sensor. When selecting the temperature sensor 5, if a thermocouple temperature sensor 5 is used, the material of the thermocouple should be selected based on the actual measurement temperature range and accuracy requirements. If a thermal resistor temperature sensor 5 is used, the appropriate resistor material and packaging type should be selected based on the specific environmental conditions and measurement accuracy requirements.
[0025] In a preferred embodiment, the control unit includes a microcontroller 6 and a drive circuit. The microcontroller 6 receives temperature signals and controls the cooling unit via the drive circuit. The microcontroller 6 is a single-chip microcomputer or PLC with stable performance and fast response speed. The drive circuit utilizes a highly integrated chip and circuit design with strong anti-interference capabilities. The microcontroller 6 receives signals from the temperature sensor 5, rapidly processes and analyzes them, and sends control instructions to the cooling unit via the drive circuit.
[0026] As a preferred embodiment, the cooling unit includes a coolant circulation system, which includes a water tank 7, a water pump 8, a radiator 9, and a pipeline 10. The water tank 7 is fixedly connected to the top of the bracket 4. Coolant is provided in the water tank 7. Both sides of the water tank 7 are connected to the pipeline 10. The pipeline 10 is arranged around the generator body 1 and passes through the water pump 8 and radiator 9 fixed to the bracket 4. The water pump 8 pumps the coolant in the water tank 7 into the pipeline 10 and passes through the generator body 1, thereby absorbing the heat dissipated by the generator body 1 during operation. After absorbing the heat, the coolant dissipates the heat through the radiator 9 and returns to the water tank 7. It should be noted that the water tank 7 is made of a corrosion-resistant and well-sealed material, the water pump 8 is a model with moderate power and stable flow, and the pipeline 10 is made of a high-temperature and high-pressure resistant material.
[0027] As a preferred embodiment, the cooling unit includes a fan 11, which is fixedly connected to the bracket 4 and is arranged toward the pipeline 10 and the generator body 1. The fan 11 is installed at a specific position on the bracket 4 so that its wind direction is directly aimed at the generator body 1, thereby accelerating air flow and achieving an air cooling effect. At the same time, the fan 11 also blows the cold air emitted by the coolant in the pipeline 10 toward the generator body 1 to dissipate heat.
[0028] In a preferred embodiment, the water tank 7 is equipped with a liquid level sensor 12 and a water temperature sensor 13. These sensors are installed at specific locations within the water tank 7 and are connected to the control unit via wiring. The liquid level sensor 12 monitors the liquid level in the water tank 7 in real time and transmits this data to the control unit. The water temperature sensor 13 accurately measures the temperature of the coolant in the water tank 7, providing important parameters for the control unit.
[0029] In a preferred embodiment, an alarm unit 14 is fixedly connected to bracket 4 and connected to the control unit. Alarm unit 14 includes an audible and visual alarm, which is mounted in a location easily noticeable to the operator, such as a conspicuous portion of the equipment. When the control unit determines that the temperature of generator body 1 exceeds a set warning value, it immediately sends a signal to alarm unit 14, triggering the audible and visual alarm to emit a strong audible and visual alarm, prompting the operator to take timely action.
[0030] The sound and light alarm uses high-brightness lights and loud sound equipment to ensure that it can attract the attention of operators even in noisy environments. The light color can be selected as eye-catching red or yellow, and the sound can be a continuous alarm or intermittent warning sound to enhance the warning effect.
[0031] As a preferred embodiment, the fixing structure includes a card groove 15 arranged on the inner wall of the bracket 4 and a card block 16 on the edge of the mounting plate 3. The card block 16 and the card groove 15 are engaged with each other. When the mounting plate 3 enters the bracket 4, the card groove 15 on the inner wall of the bracket 4 and the card block 16 on the edge of the mounting plate 3 are precisely engaged with each other, thereby firmly fixing the position of the mounting plate 3.
[0032] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology, which will not be described in detail here.
