All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6 , the present utility model provides a technical solution: an overheat protection device for the protection of automatic instruments and meters, including, a connection block 12 is fixedly installed at the right end of the first ferrule 1, and a second ferrule 2 is connected to the right side of the connection block 12. A heat protection plate 5 is fixedly installed on the left side of the first ferrule 1, and a liquid inlet pipe 6 is connected to the upper end of the heat protection plate 5. A buzzer 9 is connected to the front side of the left end of the heat protection plate 5, and a warning light 10 is connected to the rear side of the left end of the heat protection plate 5. A groove 14 is opened in the middle side of the interior of the heat protection plate 5, and a protection structure is connected to the outside of the heat protection plate 5. A connection pipe 7 is fixedly installed in the middle side of the right end of the heat protection plate 5. Coolant is poured into the inside of the heat protection plate 5 through the liquid inlet pipe 6, and then the OMEGA temperature sensor arranged inside the thermal grease layer 3 detects that the temperature of the instrument and meter is too high, causing the buzzer 9 and the warning light 10 to start operating and giving a reminder. As a result, the coolant inside the groove 14 flows into the inside of the coolant pipe 4 through the connection pipe 7. Furthermore, the cold temperature of the coolant is conducted to the instrument and meter through the coolant pipe 4, ensuring a good overheat protection effect for the instrument and meter. Moreover, through the thermal grease layers 3 fixedly installed on the inner sides of both the first ferrule 1 and the second ferrule 2, it is convenient to conduct heat to the instrument and meter. The protection structure arranged on the outside of the heat protection plate 5 facilitates the protection of the buzzer 9 and the warning light 10;

[0030] A fixing plate 11 is fixedly installed on the outer side of the left end of the second ferrule 2, and a fixing rod 13 is connected to the outside of the fixing plate 11. Thermal grease layers 3 are installed on the inner sides of both the first ferrule 1 and the second ferrule 2, and a coolant pipe 4 is connected inside the thermal grease layer 3. The first ferrule 1 is snap-fitted on the outside of the instrument and meter, and then the second ferrule 2 is placed on the right side of the first ferrule 1, so that the second ferrule 2 is installed on the outside of the connection block 12. As a result, the second ferrule 2 drives the fixing plate 11 to be installed on the outside of the first ferrule 1. Rotate the fixing rod 13 so that the fixing rod 13 is connected in the middle of the fixing plate 11, and thus the fixing rod 13 is connected on the outside of the first ferrule 1, facilitating the installation of the heat protection plate 5.

[0031] When using this overheat protection device for the protection of automatic instruments and meters, specifically as Figure 1 、 Figure 2 and Figure 3In it, the first ferrule 1 is snap-fitted and installed on the outside of the instrument. The connecting block 12 and the second ferrule 2 are connected by a snap-fitting method, and the connecting block 12 is symmetrically distributed before and after the center line of the second ferrule 2. Then, the second ferrule 2 is placed on the right side of the first ferrule 1, and the second ferrule 2 is snap-fitted and installed on the outside of the connecting block 12, so that the second ferrule 2 drives the fixed plate 11 to be snap-fitted and installed on the outside of the first ferrule 1. The fixed plate 11 and the fixed rod 13 are connected by a threaded method, and the cross-sectional shape of the fixed plate 11 is an arc structure. Rotate the fixed rod 13 so that the fixed rod 13 is threadedly connected in the middle of the fixed plate 11, so that the fixed rod 13 is threadedly connected on the outside of the first ferrule 1, which is convenient for installing the overheat protection plate 5;

[0032] Specifically, as Figure 4 , Figure 5 and Figure 6 In it, since the protection plate 8 and the limit rod 16 are connected by a rotating method, and the cross-sectional shape of the protection plate 8 is a "U"-shaped structure. Through the rotating connection between the protection plate 8 and the limit rod 16, the protection plate 8 is rotated to the left side of the overheat protection plate 5. The protection plate 8 and the mounting rod 15 are connected by a threaded method, and the mounting rod 15 is symmetrically distributed before and after the center line of the protection plate 8. Rotate the mounting rod 15 so that the mounting rod 15 is threadedly connected on the outside of the right end of the protection plate 8, so that the mounting rod 15 is threadedly connected on the outside of the overheat protection plate 5, which is convenient for protecting the buzzer 9 and the warning light 10;

[0033] Specifically, as Figure 1 , Figure 2 and Figure 6 In it, coolant is poured into the inside of the overheat protection plate 5 through the liquid inlet pipe 6. Then, when the OMEGA temperature sensor arranged inside the thermal grease layer 3 detects that the temperature of the instrument is too high, the thermal grease layer 3 and the coolant pipe 4 are connected by a snap-fitting method and play a role in cooling the instrument, so that the buzzer 9 and the warning light 10 start to operate and remind. Thus, the coolant inside the groove 14 flows into the inside of the coolant pipe 4 through the connecting pipe 7. Furthermore, the cold temperature of the coolant is conducted to the instrument through the coolant pipe 4, ensuring good overheat protection effect for the instrument. The thermal grease layer 3 and the first ferrule 1 are connected by an adhesive. Then, through the thermal grease layer 3 fixedly installed on the inner sides of both the first ferrule 1 and the second ferrule 2, it is convenient to conduct heat for the instrument.
