具体实施方式 Detailed ways
下面结合实施例对本发明作进一步地详细说明，但本发明的实施方式并不限于此。 The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.
实施例 Example
如图1所示，本发明包括发动机水箱1，温度传感器2，电磁阀3，吸水泵4，冷却器5，过滤器6，触发系统7，出水管8，进水管9，信号偏置放大处理系统10。为了能够实现对水温的控制，该冷却器5的进水口通过出水管8与发动机水箱1相连接，以便发动机水箱1内的高温水可以通过出水管8输入到冷却器5中。而冷却器5的出水口则通过进水管9与发动机水箱1相连接，以便由冷却器5冷却后的冷却水可以通过进水管9输送回发动机水箱1内。电磁阀3则设置在出水管8上，而吸水泵4设置在出水管8上且位于电磁阀3与冷却器5之间。过滤器6设置在进水管9上，温度传感器2则设置在发动机水箱1底部，所述电磁阀3、吸水泵4均与触发系统7相连接。信号偏置放大处理系统10的输入端与温度传感器2的输出端相连接，其输出端则与触发系统7的输入端相连接。 As shown in Figure 1, the present invention includes engine water tank 1, temperature sensor 2, solenoid valve 3, suction pump 4, cooler 5, filter 6, trigger system 7, water outlet pipe 8, water inlet pipe 9, signal bias amplification processing System 10. In order to be able to control the water temperature, the water inlet of the cooler 5 is connected to the engine water tank 1 through the water outlet pipe 8, so that the high temperature water in the engine water tank 1 can be input into the cooler 5 through the water outlet pipe 8. The water outlet of the cooler 5 is connected to the engine water tank 1 through the water inlet pipe 9, so that the cooling water cooled by the cooler 5 can be transported back in the engine water tank 1 through the water inlet pipe 9. The solenoid valve 3 is arranged on the water outlet pipe 8 , and the water suction pump 4 is arranged on the water outlet pipe 8 and is located between the solenoid valve 3 and the cooler 5 . The filter 6 is arranged on the water inlet pipe 9, the temperature sensor 2 is arranged on the bottom of the engine water tank 1, and the electromagnetic valve 3 and the suction pump 4 are all connected with the trigger system 7. The input end of the signal bias amplification processing system 10 is connected to the output end of the temperature sensor 2 , and its output end is connected to the input end of the trigger system 7 .
温度传感器2可以检测发动机水箱1内冷却水的温度，并把温度信号转变为电压信号输出给信号偏置放大处理系统10。该温度传感器2采用深圳市铂电科技有限公司生产的BD-WZP-PT100型温度传感器来实现。如冷却水的温度在40℃以下时，温度传感器2所发出的电压信号较弱，这时信号偏置放大处理系统10则不工作。当冷却水温度超过40℃后，温度传感器2所发出的电压信号变强，这时信号偏置放大处理系统10开始工作，使触发系统7得电工作。这时由触发系统7控制电磁阀3打开以及吸水泵4启动。而发动机水箱1内的高温冷却水则通过出水管8输送到冷却器5进行冷却，冷却后的冷却水经过滤器6过滤后通过进水管9输送回发动机水箱内继续使用，经过滤器6过滤后的冷却水更加清洁。 The temperature sensor 2 can detect the temperature of the cooling water in the engine water tank 1 , and convert the temperature signal into a voltage signal and output it to the signal bias amplification processing system 10 . The temperature sensor 2 is implemented by a BD-WZP-PT100 temperature sensor produced by Shenzhen Platinum Technology Co., Ltd. If the temperature of the cooling water is below 40° C., the voltage signal sent by the temperature sensor 2 is weak, and the signal bias amplification processing system 10 does not work at this time. When the temperature of the cooling water exceeds 40° C., the voltage signal sent by the temperature sensor 2 becomes stronger. At this time, the signal bias amplification processing system 10 starts to work, so that the trigger system 7 is energized to work. At this time, the electromagnetic valve 3 is controlled by the trigger system 7 to open and the suction pump 4 starts. The high-temperature cooling water in the engine water tank 1 is delivered to the cooler 5 through the water outlet pipe 8 for cooling, and the cooled cooling water is filtered by the filter 6 and then sent back to the engine water tank by the water inlet pipe 9 to continue using. Cooling water is cleaner.
