Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and in particular relates to a quick-release pipe clamp type temperature transmitter. Background Technology

[0002] Pipe clamp temperature transmitters are mainly used for measuring pipeline temperature. Their main structure includes a pipe clamp, a protective tube, and an electrical compartment (or meter head). Figure 1 As shown, a temperature sensor is installed at the bottom of the pipe clamp, and a transmitter module is installed in the electrical compartment. A protective tube is placed between the pipe clamp and the electrical compartment, containing a lead wire for connecting the temperature sensor and the transmitter module. During use, the pipe clamp is fixed to the outer wall of the pipe with bolts. To avoid the influence of ambient temperature on the sensor sampling during temperature measurement, the pipe clamp temperature sensor needs to be insulated during the measurement process. Specifically, insulation materials such as glass wool, rock wool, or rubber plastic are used to wrap the pipe, the pipe clamp of the temperature transmitter installed on it, and the mounting bracket together to form an outer insulation shell. However, when the temperature transmitter is calibrated, repaired, or replaced, the insulation layer needs to be removed, the sensor needs to be removed by unscrewing screws, a new sensor needs to be installed by unscrewing screws, and the insulation layer needs to be reinstalled, which is complicated, time-consuming, and labor-intensive.

[0003] Based on the above analysis, the applicant designed a novel clamp-type temperature sensor. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release pipe clamp temperature transmitter. This temperature transmitter adopts a split design for the support pipe seat and the temperature sensing rod. Later maintenance only requires replacing or disassembling the temperature sensing rod, eliminating the need for frequent disassembly and assembly of the support pipe seat and insulation layer, thus improving the convenience of use and the speed of disassembly and assembly.

[0005] To address the aforementioned issues, this application provides a quick-release clamp-type temperature transmitter, comprising a temperature sensing rod and a support tube base. The temperature sensing rod includes a probe end and a connecting end, and the support tube base includes a clamp seat and a support tube. The clamp seat has a built-in heat-conducting core. The probe end of the temperature sensing rod can extend into the support tube and contact the heat-conducting core. Simultaneously, the connecting end of the temperature sensing rod can be detachably connected to the support tube.

[0006] As a preferred embodiment, the heat-conducting core is a hollow cylindrical structure, and the hollow cavity of the heat-conducting core has a variable diameter structure with a larger upper diameter and a smaller lower diameter.

[0007] As a preferred embodiment, the heat-conducting core is provided with external threads, and the tube clamp is provided with internal threads. The heat-conducting core is detachably installed in the tube clamp through the cooperation of the internal and external threads.

[0008] As a preferred embodiment, the connecting end includes an upper threaded interface and a lower threaded interface. The upper threaded interface is used to connect with the electrical compartment, and the lower threaded interface is used to detachably connect with the support tube.

[0009] As a preferred embodiment, the support tube and the tube clamp are integrally formed, or the support tube is screwed onto the tube clamp.

[0010] As a preferred embodiment, the probe end is equipped with a temperature sensor, which is a PT100 temperature sensor.

[0011] As a preferred embodiment, the heat-conducting core is made of any one of copper, copper alloy, or aluminum alloy.

[0012] As a preferred embodiment, both the pipe clamp and the support pipe are made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This quick-release clamp-type temperature transmitter mainly includes a temperature sensing rod and a support tube base. The support tube base has a built-in heat-conducting core. The probe end of the temperature sensing rod can extend into the support tube base and contact the heat-conducting core to collect temperature data. Simultaneously, after the probe end extends into the designated position of the support tube base, the connecting end of the temperature sensing rod can be detachably connected to the support tube of the support tube base to complete assembly. In use, the support tube base, as a fixed component, will be permanently or long-term fixed to the pipeline, while the temperature sensing rod, as a moving component, is detachably connected to the support tube base. This facilitates subsequent maintenance and replacement of the sensing components, avoiding the drawbacks of traditional structures that require frequent removal of the support tube base and the insulation layer surrounding it when replacing or maintaining the sensing components. This improves installation efficiency and operational flexibility, while also saving operating costs, addressing existing shortcomings, and possessing certain market value and economic benefits.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0021] like Figure 2-3 As shown, this embodiment provides a quick-release pipe clamp type temperature transmitter. The temperature transmitter includes a temperature sensing link 20 and a support pipe seat 10. The temperature sensing link 20 includes a probe end 201 and a connecting end 202. The probe end 201 is used to sense temperature and should be equipped with a temperature sensor; in this embodiment, the temperature sensor is preferably a PT100. The connecting end 202 includes an upper threaded interface 203 and a lower threaded interface 204. The upper threaded interface 203 is used to connect to the electrical compartment 30, and the lower threaded interface 204 is used to mate with the support pipe seat 10. In this embodiment, the length of the temperature sensing link 20 can be designed according to actual needs; this embodiment does not impose a specific limitation. The support pipe seat 10 includes a pipe clamp seat 101 and a support pipe 102. The pipe clamp seat 101 has a built-in heat-conducting core 103 and is used to fix it to the pipe. In this embodiment, the length of the pipe clamp seat 102 is preferably a PT100. The pipe clamp 101 is equipped with a flange or threaded interface, which connects to the pipeline. The heat-conducting core 103, as a heat conduction unit, can quickly conduct the temperature on the pipeline to its body. That is, the temperature of the heat-conducting core 103 can be synchronized with the pipeline. The probe end 201 of the temperature sensing rod 20 can extend into the support tube 102 and contact the heat-conducting core 103 to sense the temperature of the heat-conducting core 103 in a timely manner. At the same time, the connecting end 202 of the temperature sensing rod 20 can be detachably connected to the support tube 102. In this embodiment, a threaded connection is preferred for detachable connection. It can be understood that an internal thread should be provided at the corresponding position of the support tube 102. That is, after the lower threaded interface 204 of the temperature sensing rod 20 is connected to the internal thread of the support tube 102, the probe end 201 of the temperature sensing rod 20 is in contact with the heat-conducting core 103.

[0022] Specifically, in this embodiment, the temperature sensing rod 20 and the support tube seat 10 are connected by a threaded detachable connection. After the connection is completed, the probe end 201 of the temperature sensing rod 20 can contact the heat-conducting core 103 inside the support tube seat 10 to sense the pipe temperature. Since the temperature of the heat-conducting core 103 is synchronized with the pipe temperature, the real-time pipe temperature can be quickly sensed or measured. It can be seen that the temperature transmitter of this embodiment can not only realize the effective measurement of pipe temperature, but also provide convenience for subsequent maintenance and replacement of the temperature sensing rod 20 by designing the temperature sensing rod 20 and the support tube seat 10 separately, thus eliminating the drawbacks of the traditional integrated design structure.

[0023] As a preferred embodiment, the exterior of the heat-conducting core 103 is a variable-diameter hollow cylindrical structure. Simultaneously, the hollow cavity of the heat-conducting core 103 has a variable-diameter structure, with the upper part larger than the lower part; that is, the hollow cavity near the pipe end is smaller. Figure 4-5 As shown, the advantages of the heat-conducting core 103 of this structure are: first, it facilitates the insertion of the probe end 201 of the temperature sensing link 20 into the hollow cavity of the heat-conducting core 103, thereby improving the temperature sensing efficiency; second, while increasing the contact area between the heat-conducting core 103 and the pipe, it also improves the heat diffusion efficiency by using a smaller hollow cavity pipe diameter, thereby further improving the temperature sensing efficiency.

[0024] In this embodiment, the size of the hollow cavity at the upper end of the heat-conducting core 103 is preferably slightly larger than the size of the probe end 201 of the temperature sensing link 20, so as to ensure that it can contact the probe end 201, thereby achieving rapid and accurate temperature acquisition.

[0025] In a preferred embodiment, the heat-conducting core 103 has an external thread, and the pipe clamp 101 has an internal thread. The heat-conducting core 103 is detachably mounted in the pipe clamp 101 through the engagement of the internal and external threads. Figure 4 As shown, the heat-conducting core 103 is detachably connected to the pipe clamp seat 101. This installation structure facilitates the replacement and maintenance of the heat-conducting core 103. Of course, in other specific embodiments of this example, the heat-conducting core 103 can also be fixed in the pipe clamp seat 101 by hot casting or bonding.

[0026] As a preferred embodiment, the heat-conducting core 103 is made of any one of copper, copper alloy or aluminum alloy. In this embodiment, copper is preferred, which has a thermal conductivity of about 400 W / m·K and is an excellent heat-conducting material.

[0027] As a preferred embodiment, both the pipe clamp seat 101 and the support pipe 102 are made of stainless steel, and the stainless steel support pipe 102 and support pipe seat 10 mainly serve a protective function.

[0028] As a preferred embodiment, the support tube 102 is integrally formed with the tube clamp seat 101, or the support tube 102 is screwed onto the tube clamp seat 101. The specific design can be made according to actual needs. In this embodiment, the support tube 102 is preferably screwed onto the tube clamp seat 101.

[0029] The specific operating principle of this temperature transmitter in this embodiment includes: During installation: First, fix the support tube seat 10 to the pipe with bolts and wrap it with insulation material (such as glass wool, rock wool or rubber plastic) to form an insulation layer. Then, insert the probe end 201 of the temperature sensing rod 20 into the support tube seat 10 and use internal and external thread screw connection to connect the lower thread interface 204 with the internal thread of the end of the support tube 102 until the probe end 201 extends into the hollow cavity of the heat conducting core 103. It can be understood that the electrical compartment 3030 can be installed in advance or after the pipe installation is completed at the upper thread interface 203 of the temperature sensing rod 2020.

[0030] In use, since the heat-conducting core 103 is in contact with the pipeline and can quickly conduct and diffuse heat, the pipeline temperature can be indirectly sensed through the heat-conducting core 103 after the probe end 201 contacts the heat-conducting core 103, thereby realizing real-time and accurate measurement of the pipeline temperature. In addition, when maintenance or other operations are required, it is only necessary to separate the temperature sensing link 20 from the support pipe seat 10, avoiding the drawback of the traditional structure that requires frequent removal of the support pipe seat 10 and the insulation layer wrapped around it when replacing or maintaining the temperature sensing link 20. This improves installation efficiency and usage flexibility, while also saving usage costs, solving existing shortcomings, and has certain market value and economic benefits.

[0031] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various improvements without departing from this utility model, and these improvements should also be considered within the scope of protection of this utility model. These improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of the claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
