Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 schematically shows a temperature monitoring device 1 according to an embodiment of the invention. As shown in fig. 1, the temperature monitoring device 1 includes a temperature sensing assembly 100 and a display 200. The temperature sensing assembly 100 includes a sorbent assembly 101 and a temperature sensor 102 integrated with the sorbent assembly 101. The display 200 communicates with the temperature sensor 102 and displays the temperature value measured by the temperature sensor 102. In using the temperature monitoring device 1, the adsorption member 101 is attached to the object to be measured, and the temperature sensor 102 is brought into direct contact with the object to be measured and detects the temperature of the object to be measured.
According to the temperature monitoring device 1, since the adsorption component 101 and the temperature sensor 102 are combined together, after the adsorption component 101 is adsorbed to an object to be measured (such as a hydraulic oil tank 502 of a heading machine 501 shown in fig. 4), the temperature sensor 102 can be in close contact with the object to be measured, so that the temperature of the object to be measured can be measured. In addition, for the heading machine 501, the temperature monitoring device 1 is very simple and convenient to use, and the heading machine 501 does not need to be modified at all, which greatly reduces the use cost of the temperature monitoring device 1.
The adsorbent 104 may be in any form, such as vacuum adsorption or magnetic adsorption.
Fig. 2 schematically shows the structure of the temperature sensing assembly 100. As shown in fig. 2, the adsorption assembly 101 includes an adsorption body 104 having a through mounting hole 103, and the temperature sensor 102 is fixedly mounted in the through mounting hole 103 of the adsorption body 104. In one embodiment, the adsorbent body 104 is ring-shaped with a central hole forming the through mounting hole 103. Thus, the temperature sensor 102 is installed at the center of the absorbent body 104, which makes the absorbent body 104 uniformly stressed in the circumferential direction, thereby stably supporting the temperature sensor 102.
In a specific embodiment, the absorber 104 is a ring magnet, and the temperature sensor 102 is installed in a central hole 103 of the ring magnet and fixedly connected with the ring magnet through a heat-conducting glue 105. The mass of the ring magnet 104 is much larger than that of the temperature sensor 102, so that the temperature sensor 102 hardly affects the arrangement position of the ring magnet 104 or the temperature sensing assembly 100 on the object to be measured, such as the hydraulic oil tank 502 of the heading machine 501, which greatly facilitates the application of the temperature sensing assembly 100. In addition, the temperature sensor 102 is fixedly connected with the annular magnet 104 through the heat conducting glue 105, so that the temperature sensor 102 and the annular magnet 104 can be in close contact, and inaccurate temperature monitoring caused by heat loss due to gaps in the heat transfer process is avoided. In one embodiment, the thermally conductive paste 105 may be thermally conductive silicone grease.
Fig. 3 shows a detailed structure of a portion a of fig. 2. As shown in fig. 3, the sensor head 106 of the temperature sensor 102 is flush with the attachment surface 107 of the ring magnet 104. Thus, when the ring magnet 104 is attached to the object with its attachment surface 107, the sensor head 106 of the temperature sensor 102 is naturally in close contact with the object, thereby facilitating accurate temperature monitoring of the object.
As also shown in fig. 3, on the attachment surface 107 of the ring magnet 104, a gap 108 exists between the sensor head 106 of the temperature sensor 102 and the sidewall of the central bore 103. Thus, after the ring magnet 104 is attached to the object, the gap 108 can accommodate a portion of roughness or unevenness on the surface of the object, so that the sensor head 106 of the temperature sensor 102 can be in closer contact with the object, thereby facilitating accurate monitoring of the temperature of the object. In a particular embodiment, the central bore 103 forms a flare as a gap 108 on the attachment surface 107 of the ring magnet 104, with the sense head 106 of the temperature sensor 102 centered in the flare. The flare is easily machined to shape, thereby contributing to a reduction in the production cost of the temperature monitoring device 1.
As shown in fig. 1, the temperature monitoring device 1 further includes a cable 110. The cable 110 is electrically connected to the temperature sensor 102 at a first end and to the display 200 at a second end. In this way, the display 200 receives temperature data measured by the temperature sensor 102 via the cable 110. The communication mode is very stable, and is favorable for stably monitoring the temperature of the object to be detected.
As shown in fig. 2, the temperature monitoring device 1 further includes a first housing 111 accommodating the temperature sensing assembly 100 and a second housing 112 accommodating a first end of the cable 110. The first housing 111 and the second housing 112 are detachably connected. The first housing 111 is used to protect the temperature sensing assembly 100, and the second housing 112 is used to protect the first end of the cable 110. Second housing 112 also serves to protect the splice portion of cable 110 and temperature sensor 102 from accidental damage after cable 110 is electrically connected to temperature sensor 102.
In one embodiment, an external thread is formed on the second housing 112 and an internal thread is formed on the first housing 111, so that the first housing 111 and the second housing 112 can be detachably coupled by a screw connection.
In another embodiment, the first shell 111 and the second shell 112 are made of nylon. For example, a nylon rod of an appropriate size may be selected and then machined to make the first and second housings 111 and 112.
Figure 4 shows schematically a ripping apparatus 5 according to the present invention. As shown in fig. 4, the heading equipment 5 includes a heading machine 501 and the temperature monitoring device 1 according to the above. The heading machine 50 is provided with a hydraulic oil tank 502, the adsorption component 101 of the temperature monitoring device 1 is adsorbed on the outer wall of the hydraulic oil tank 502, and the temperature sensor 1 is in direct contact with the outer wall of the hydraulic oil tank 502. The display 200 may be placed near the driver of the heading machine 50 so that the driver can monitor the temperature of the hydraulic oil at any time and take appropriate action.
The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
