In this application, the ventilation passageway can be a plurality of and the inside air vent that communicates of safety cover that sets up on the safety cover circumferentially.
When the special thermistor for the bullet train is used, the connector can be fixed on the bullet train to enable the ventilation channel to correspond to the air outlet of the air conditioner, so that the protective cover protects the temperature measuring element at the outer side of the temperature measuring element, and larger impurities mixed with air flow blown out of the air outlet of the air conditioner are prevented from directly colliding with the temperature measuring element of the thermistor to damage the temperature measuring element; the air current that the air conditioner blew out can directly contact with the temperature element through the ventilation passageway, and the data deviation that thermistor detected is less.
In practical use, the air outlet of the air conditioner is in direct contact with the temperature measuring element only on the windward side, so that the actual temperature of the leeward side and the windward side of the temperature measuring element has a relatively crossed deviation and cannot meet the requirement of people on higher accuracy, and therefore, the applicant also designs the temperature measuring element as follows: the vent holes are strip-shaped holes 6-1 which are parallel to the temperature measuring element, and a support body 6-2 is formed between every two adjacent strip-shaped holes; an internal thread is arranged at one end, close to the insulating tube, of the inner side of the protective cover, an external thread 6-3 matched with the internal thread is arranged at one end, close to the protective cover, of the insulating tube, a partition plate 3 is arranged at one side, far away from the insulating tube, of the internal thread in the protective cover, and a central hole 3-1 for a temperature measuring element to penetrate through is formed in the partition plate; a semicircular baffle 7 is arranged on one side in the protective cover, one end of the semicircular baffle is connected with the partition plate, and the other end of the semicircular baffle is connected with a semicircular guide plate 8; a semicircular blocking body 9 is arranged on the other side in the protective cover, one end, far away from the insulating tube, of the semicircular blocking body is integrally arranged with the protective cover, and a space is reserved between the other end of the semicircular blocking body and the partition plate to form an air outlet; the semicircular blocking body and the semicircular baffle are connected into a whole, so that a cylindrical space 10 is formed between the semicircular blocking body and the inner side of the semicircular baffle, and the front end of the temperature measuring element is positioned in the cylindrical space. Referring to fig. 5, when the structure is installed, the semicircular guide plate is installed corresponding to the air-conditioning air outlet, and by arranging the semicircular baffle plate, the semicircular guide plate and the semicircular blocking body, after the air flow of the air-conditioning air outlet is blown out, part or all of the air flow enters the protective cover through the left space of the semicircular guide plate, then the air flow is pushed to the right side through the left side of the cylindrical space 10 until the air flow reaches the air outlet, and the air flow is discharged through the air outlet and the corresponding strip-shaped hole. As a preferable embodiment, the semicircular blocking body and the semicircular baffle are provided with inclined parts at positions of the cylindrical space far away from one end of the insulating tube, and the two inclined parts form a truncated cone-shaped channel at one end of the cylindrical space far away from the insulating tube, and the diameter of one end of the truncated cone-shaped channel close to the insulating tube is smaller than that of the other end of the truncated cone-shaped channel. Therefore, the airflow is drawn close to the temperature measuring element after passing through the circular truncated cone-shaped channel, and the airflow is favorably pushed along the surface of the temperature measuring element.
In actual manufacturing, the semicircular blocking body is preferably provided with an inclined surface 9-1 on one surface opposite to the cylindrical space, and the distance between one end of the inclined surface close to the insulating tube and the cylindrical space is larger than the distance between the other end of the inclined surface and the cylindrical space. Therefore, the airflow can be rapidly diffused after flowing out of the air outlet.
During actual manufacturing, one end of the semicircular guide plate, which is not connected with the semicircular baffle, can be connected with the corresponding support body, and the connecting position is positioned in the middle of the support body, so that the semicircular guide plate isolates the space in the protective cover at one side, and airflow passing through the guide plate is not easy to bypass the semicircular guide plate due to blocked transfer into the space at the left side and then is discharged through the corresponding strip-shaped holes after passing through the space outside the air outlet; a gap can also be formed between one end of the semicircular guide plate, which is not connected with the semicircular baffle, and the corresponding support body, the semicircular guide plate is obliquely arranged, and one end of the semicircular guide plate, which is not connected with the semicircular baffle, is positioned at the right part of the middle part of the support body, so that the air quantity flowing through the cylindrical space is increased; the airflow channel on the right side of the semicircular guide plate is used for reducing the resistance of the protective cover to air outlet of the air conditioner.
It should be noted that the above is only an example of the present invention, and it is within the inventive concept of the present invention that a dust blocking structure is provided at a position close to the blade inside the shaft protection pipe to prevent dust from entering between the shaft protection pipe and the shaft and accumulating.
