Description

Technical Field

[0001] The utility model belongs to the technical field of temperature measurement and thermocouples, and more specifically relates to a telescopic wall-mounted bracket and a thermocouple using the bracket, which is suitable for a reaction device with a stepped inlet. Background Art

[0002] Thermocouples are commonly used temperature detection and control units in various chemical, nuclear power and other projects. They need to be able to actually reflect the temperature and provide timely feedback. More importantly, due to the different actual usage environments, various adaptability improvements need to be made to thermocouples, such as the corrosion resistance requirements of acids and alkalis, the wear resistance requirements of dust impact, and the location requirements of various special temperature measurement structures. In actual use conditions, reaction devices to be measured temperature often have special structures, such as very long tubular structures or reaction devices with different inner diameters. It is necessary to set multiple thermocouple temperature measurement points in the length direction, and the thermocouple temperature measurement points need to be centered in the metal tubular structure for temperature measurement. Therefore, the applicant's R&D team designed and applied for Chinese patents "Centralized support mounting bracket and thermocouple using this bracket" (application number 2021224760581, application date October 14, 2021), "Centralized elastic mounting bracket and thermocouple using this bracket" (application number 2021224827098, application date October 14, 2021), and "Compressible elastic expansion card and thermocouple using this expansion card" (application number 2022200846354, application date January 13, 2022).

[0003] In specific use and promotion, there are situations where the inlet and the main body of the reaction device have different radii, that is, a stepped inlet. The inner diameter of the pipe at the inlet is relatively small, and the radius of the main body of the reaction device is relatively large. In this reaction device, it is necessary to monitor the inner wall temperature of the reaction device pipe. Such a reaction device requires that the thermocouple can pass through a narrow installation channel and can achieve the wall-mounted temperature measurement point inside the main device, and can also be easily removed through the narrow installation channel. For this reaction device, the applicant's R&D team designed a central mounting bracket suitable for this reaction device, but how to achieve wall-mounted temperature measurement seriously affects the use effect of the thermocouple. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a telescopic wall-mounted bracket and a thermocouple using the bracket.

[0005] The technical purpose of the present invention is achieved through the following technical solutions.

[0006] The telescopic wall-mounting bracket includes a torsion spring and two temperature measuring terminals, wherein:

[0007] The two temperature measuring end bodies are the first temperature measuring end body and the second temperature measuring end body, and the structures of the two are basically the same, including a temperature measuring body that is basically cylindrical and a protective end head that is basically truncated cone-shaped, the two are coaxially arranged and fixedly connected as one, and the temperature measuring hole runs through the entire temperature measuring end body;

[0008] A connecting plane is provided on the outer surface of the temperature measuring body, and a first protrusion and a second protrusion are formed at both ends of the connecting plane respectively;

[0009] The first temperature measuring end body and the second temperature measuring end body are on the same horizontal line, and the protective ends of the two temperature measuring end bodies are in opposite directions, and the temperature measuring holes of the two temperature measuring end bodies are opposite; the two ends of the torsion spring are respectively connected to the second protrusions of the first temperature measuring end body and the second temperature measuring end body;

[0010] The first temperature measuring end body and the second temperature measuring end body are connected by a connecting component and can move along the connecting component; protrusions are respectively set at both ends of the connecting component; the two ends of the connecting component respectively pass through the first protrusion of the first temperature measuring end body and the first protrusion of the second temperature measuring end body.

[0011] In the above technical solution, connecting holes are provided on the second protrusions of the two temperature measuring end bodies, and the two ends of the torsion spring are respectively provided in the connecting holes, and a fixed or movable connection is selected.

[0012] In the above technical solution, a through hole is provided on the connection plane of the first temperature measuring end body or the second temperature measuring end body, and a fastening screw is provided in the through hole to press and fix the thermocouple temperature measuring core located in the temperature measuring hole; the number of through holes is 1-4.

[0013] In the above technical solution, the number of temperature measuring holes is 1-2.

[0014] Using the thermocouple of the above-mentioned telescopic wall-mounted bracket, the thermocouple temperature measuring core passes through the temperature measuring holes of the first temperature measuring end body and the second temperature measuring end body. According to the design requirements, the temperature measuring point of the thermocouple temperature measuring core is set in the temperature measuring hole of the temperature measuring body and fixed, such as by tightening screws.

[0015] The thermocouple temperature measurement core adopts thermocouple temperature measurement armored wire, and adopts single-branch multi-point thermocouple armored wire to realize temperature measurement of multiple points along the length direction of the reaction device by one thermocouple temperature measurement core.

During installation, the bent portion of the torsion spring contacts and squeezes the inner wall of the pipe. Since the torsion spring is connected to the two temperature measuring end bodies and there is a connection between the two temperature measuring end bodies, the two temperature measuring end bodies are set against the wall, and the thermocouple temperature measuring core body set therein achieves temperature measurement against the wall. When encountering a stepped inlet, whether it is installed into the reaction device or removed from the reaction device, the truncated cone-shaped protective ends of the two temperature measuring end bodies serve to facilitate the installation of the entire thermocouple.

[0023] The technical solution of the present utility model is further described below with reference to specific embodiments.

[0024] like Figure 1 and 2 As shown, the telescopic wall-mounted bracket of the present invention includes a torsion spring and two temperature measuring end bodies, wherein:

[0025] The two temperature measuring end bodies are the first temperature measuring end body 2-1 and the second temperature measuring end body 2-2. The structures of the two are basically the same, including a temperature measuring body 7 that is basically cylindrical and a protective end head 4 that is basically truncated into a cone shape. The two are coaxially arranged and fixedly connected as one, and the temperature measuring hole 3 runs through the entire temperature measuring end body, that is, runs through the temperature measuring body 7 and the protective end head 4.

[0026] A connecting plane 7-1 is provided on the outer surface of the temperature measuring body. Since the connecting plane is lower than the circumferential surface of the temperature measuring body, a first protrusion 8-1 and a second protrusion 8-2 are formed at both ends of the connecting plane respectively. The first protrusion 8-1 is equivalent to a component of the temperature measuring body, and the second protrusion 8-2 is equivalent to a combined part of the temperature measuring body and the protective end.

[0027] The first temperature measuring end body and the second temperature measuring end body are on the same horizontal line, and the protective ends of the two temperature measuring end bodies are in opposite directions; the two ends of the torsion spring are respectively connected to the second protrusions of the first temperature measuring end body and the second temperature measuring end body.

[0028] Connection holes are optionally provided on the second protrusions of the two temperature measuring end bodies, and both ends of the torsion spring are respectively provided in the connection holes, and a fixed or movable connection is selected.

[0029] The first temperature measuring end body and the second temperature measuring end body are connected by a connecting component and can move along the connecting component; protrusions are respectively set at both ends of the connecting component; the two ends of the connecting component respectively pass through the first protrusion of the first temperature measuring end body and the first protrusion of the second temperature measuring end body.

[0030] Two through holes are selected to be set on the connection plane of the second temperature measuring end body, and fastening screws are set in the through holes to press and fix the thermocouple temperature measuring core located in the temperature measuring holes; the thermocouple temperature measuring core in the first temperature measuring end body remains active.

[0031] like Figure 3 and 4 As shown, for thermocouples, a thermocouple temperature measuring core is selected to pass through the temperature measuring holes of the first and second temperature measuring end bodies. The temperature measuring points of the thermocouple temperature measuring core are set in the temperature measuring holes of the temperature measuring body according to design requirements and can be fixed with fastening screws. The number of temperature measuring holes is 1-2. During installation, the curved portion of the torsion spring contacts and squeezes the inner wall of the pipe. Because the torsion spring is connected to the two temperature measuring end bodies and there is a connection between the two temperature measuring end bodies, the two temperature measuring end bodies are installed against the wall, and the thermocouple temperature measuring core installed therein can achieve wall-mounted temperature measurement.

[0032] The thermocouple temperature measurement core 9 adopts a thermocouple temperature measurement armored wire, such as a single-branch multi-point thermocouple armored wire, so as to achieve temperature measurement at multiple points along the length direction of the reaction device using one thermocouple temperature measurement core.

[0033] When encountering a stepped inlet, in the installation direction, since its protective end is in the shape of a truncated cone, the first temperature measuring end body can more easily pass through the stepped inlet and drive the entire thermocouple into the reaction device; when taking it out, the truncated cone-shaped protective end of the other temperature measuring end body plays the same role, making it easier to take out the entire thermocouple.

[0034] At the same time, given that the two temperature measuring ends can move along the connecting parts and the protruding points limit their range of movement, and the torsion spring and the two temperature measuring ends can be fixedly connected, or one is fixedly connected and the other is movable, the entire bracket provides adaptability and flexibility in design according to actual conditions.

[0035] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" are used in the embodiments to illustrate the relationship between an element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or located in other orientations), and the spatial relative descriptions used here can be interpreted accordingly. Relational terms such as "first" and "second" are merely used to distinguish one from another component with the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0036] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other technical personnel in this field without expending creative labor falls within the scope of protection of the present invention.
