The insulation mechanism 4 also includes a mounting cover 44, a connecting rod 45, a transmission plate 46, a fixing rod 47, and a gear 48. The mounting cover 44 is located at the right end of the protective cover 1. The connecting rod 45 is rotatably connected to the rear side of the right wall of the mounting cover 44. The outer arc of the connecting rod 45 is... A gear 48 is provided on the left side of the surface, and a transmission plate 46 is provided on the right side of the outer arc surface of the connecting rod 45. An adjustment groove is provided on the front side of the left end of the transmission plate 46. A fixing rod 47 is provided in the middle of the right end of the mounting frame 42. The fixing rod 47 is located in the mounting groove opened in the middle of the right end, and the right end of the fixing rod 47 is located inside the adjustment groove. Through the cooperation of the drive device and the gear 48, the electric heating tube 43 can be driven to perform vertical reciprocating motion, which not only ensures the heating effect but also increases the coverage area of ​​the electric heating tube 43. There is no need to consider factors such as pipe layout, which further improves the energy utilization efficiency.

[0022] It also includes a microcontroller 2, which is located at the front end of the protective cover 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply, and the input terminals of the four electric heating tubes 43 are all electrically connected to the output terminal of the microcontroller 2, which can regulate the electrical components inside the equipment.

[0023] Among them: an output rod 5 is rotatably connected to the upper side of the right wall of the mounting cover 44. A half gear 6 is provided in the middle of the outer arc surface of the output rod 5. The half gear 6 is installed in conjunction with the gear 48. When the half gear 6 and the gear 48 are meshed, the gear 48 drives the transmission plate 46 to rotate through the mounting rod 45.

[0024] Among them: a servo motor 7 is provided on the rear side of the right end of the mounting cover 44. The left end of the output shaft of the servo motor 7 is fixedly connected to the right end of the output rod 5. The input end of the servo motor 7 is electrically connected to the output end of the microcontroller 2. Through the control of the microcontroller 2, the servo motor 7 starts to run.

The rubber plug 10 is located inside the protective cover 1. The temperature detector 9 is bidirectionally electrically connected to the microcontroller 2.

[0026] Among them, springs 8 are respectively installed between the upper end of the mounting frame 42 and the top wall of the protective cover 1. The springs 8 are all sleeved on the outside of the upper side of the upright 41. The thrust generated by the extension of the springs 8 drives the mounting frame 42 to move downward and reset.

During the use of the constant temperature insulation structure for diesel engine fuel tank, the temperature detector 9 monitors the temperature inside the diesel engine fuel tank in real time. Then, the temperature detector 9 transmits the detected data to the microcontroller 2. When the temperature inside the diesel engine fuel tank is lower than the set value, the electric heating tube 43 starts to operate through the control of the microcontroller 2. The electric heating tube 43 heats the fuel through heat conduction. During the operation of the electric heating tube 43, the servo motor 7 starts to operate through the control of the microcontroller 2. The output shaft of 7 drives the output rod 5 to rotate, and the output rod 5 drives the half gear 6 to rotate. When the half gear 6 meshes with the gear 48, the gear 48 drives the transmission plate 46 to rotate through the mounting rod 45. At this time, the fixed rod 47 slides inside the adjustment groove and rotates relative to the adjustment groove, so that the transmission plate 46 drives the mounting frame 42 to move upward through the fixed rod 47. The mounting frame 42 drives the electric heating tube 43 to move upward. The spring 8 contracts. When the half gear 6 separates from the gear 48, the thrust generated by the extension of the spring 8 drives the mounting frame 42 to move downward and reset. The mounting frame 42 drives the electric heating tube 43 to move downward and reset. During the movement of the mounting frame 42, the fixed rod 47 slides inside the adjustment groove and rotates relative to the adjustment groove, so that the mounting frame 42 drives the transmission plate 46 to rotate downward and reset through the fixed rod 47, thereby driving the electric heating tube 43 to perform vertical reciprocating motion, thereby increasing the coverage area of ​​the electric heating tube 43.

[0028] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM8S207S8T6C, the electric heating tube 43 can be a YCKTR-5-1, the servo motor 7 can be an ECMA-C20604RS, and the temperature detector 9 can be an OHR-E700.
