Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature sensors, and specifically relates to an ultra-high temperature sensor. Background Technique

[0002] High-temperature sensors are a relatively common type of pressure sensor in industrial practice. They are widely used in various industrial automatic control environments. Ultra-high temperature pressure sensors use special materials, an isolated diaphragm design, and a water circulation cooling method. The measured medium temperature can reach 1000°C, and they are suitable for pressure measurement and control of engine gas and high-temperature media. Ultra-high temperature pressure sensors are involved in many industries such as oil pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electricity, ships, machine tools, pipeline air supply, boiler negative pressure, and high-temperature test machine pressure testing.

[0003] During the use of ordinary ultra-high temperature sensors, generally, the sensor is connected by inserting a connecting plug, so as to realize the connection between the host and the sensor using a data cable. While this connection method is quick and simple, it lacks firmness in connection. When subjected to external tensile force, the connection cable and the sensor will be structurally separated, thus affecting the use.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an ultra-high temperature sensor is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an ultra-high temperature sensor to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An ultra-high temperature sensor, including a connecting pipe and a connecting module. One side of the connecting pipe is connected and installed with a water cooling module, and a heat conducting pipe is installed on the side of the water cooling module away from the connecting pipe. Moreover, a temperature sensing module is connected and installed on the side of the heat conducting pipe away from the water cooling module. The connecting module is installed on the side of the connecting pipe away from the water cooling module, and a wire inserting module is connected and installed on the side of the connecting module away from the connecting pipe. The connecting module includes a control connector, a connecting jack, and a connecting screw pipe. A connecting jack is arranged and installed on one side of the control connector, and a connecting screw pipe is arranged on the side of the connecting jack away from the control connector.

[0007] Further, the connection between the connecting module and the wire inserting module is a threaded connection, and a heat conducting silicone grease is filled at the connection between the connecting module and the wire inserting module.

[0008] Further, the connecting pipe, the water cooling module, the heat conducting pipe, the temperature sensing module, and the connecting module are connected and installed on the same horizontal central axis, and the heat conducting pipe and the temperature sensing module are sealed and welded.

[0009] Furthermore, the water cooling module includes a cooling pipe, a water inlet pipe, a water outlet pipe and a connection valve. The water inlet pipe and the water outlet pipe are respectively connected and installed on the upper and lower sides of the cooling pipe, and connection valves are installed at the ends of the water inlet pipe and the water outlet pipe far away from the cooling pipe.

[0010] Furthermore, the cooling pipe, the water inlet pipe and the water outlet pipe are fixedly sealed and welded, and the water inlet pipe and the water outlet pipe have the same structure.

[0011] Furthermore, the temperature sensing module includes a heat preservation protection pipe, a temperature sensing semiconductor and a temperature sensing conductor. The temperature sensing semiconductor is installed in the center of the heat preservation protection pipe, and the temperature sensing conductors are attached to the upper and lower sides of the temperature sensing semiconductor.

[0012] Furthermore, the wiring module includes a connection plug, a connection thread and a transmission cable. The connection thread is arranged on the outer surface of the connection plug, and the transmission cable is connected to one side of the connection plug far away from the connection jack.

[0013] Furthermore, the inner surface structure of the connection screw pipe matches the outer surface structure of the connection thread, and the transmission cable is of a spiral elastic structure.

[0014] The utility model provides an ultra-high temperature sensor, which has the following beneficial effects:

[0015] 1. In the utility model, the whole water cooling module is connected to the temperature sensing module through a heat conduction pipe. After use, the high temperature contained in the temperature sensing module can be quickly conducted to the water cooling module through the heat conduction pipe. At this time, only by connecting the water inlet pipe and the water outlet pipe to an external water supply device through the connection valve, cold water can continuously flow through the inside of the cooling pipe, so as to quickly conduct the heat transferred to the whole water cooling module through the heat conduction pipe, so as to quickly and continuously dissipate the heat of the temperature sensing module, thereby protecting the whole temperature sensing module and improving the safety protection of the whole sensor's own structure.

[0016] 2. In the utility model, through the structural setting between the connection screw pipe and the connection thread, while keeping the connection module and the wiring module convenient for disassembly and assembly, the structural stability and firmness of the connection are improved through the threaded connection between the two structural parts, so as to avoid the disconnection of the connection between the whole high temperature sensor and the external monitoring host through the wiring module due to external interference during use. On the other hand, this split structure is also convenient for independent encapsulation protection of the device. The filling of thermal conductive silicone grease can, on the one hand, assist in heat dissipation between the wiring module and the connection module, and at the same time, play a sealing role to avoid moisture ingress and liquid leakage, which may damage electronic components.

[0017] 3. In this utility model, the heat-insulating and protective tube is made of ZrO2 material with a relatively common high-temperature ceramic substrate. This material has good oxidation and corrosion resistance, and can maintain stable performance even in harsh environments. At the same time, since the material processing technology of these ceramics is very mature, it can be used to prepare high-temperature sensors that can work above 1000°C, which has greatly increased the applicable range of the entire sensor and improved the practicality of the device.

[0023] The following further describes in detail the embodiments of this utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate this utility model, but cannot be used to limit the scope of this utility model.

[0024] As Figures 1 to 4As shown in the figure, a ultra-high temperature sensor includes a connecting pipe 1 and a connecting module 5. On one side of the connecting pipe 1, a water cooling module 2 is connected and installed. On the side of the water cooling module 2 away from the connecting pipe 1, a heat conduction pipe 3 is installed. On the side of the heat conduction pipe 3 away from the water cooling module 2, a temperature sensing module 4 is connected and installed. The connecting module 5 is installed on the side of the connecting pipe 1 away from the water cooling module 2. On the side of the connecting module 5 away from the connecting pipe 1, a wire plugging module 6 is connected and installed. The water cooling module 2 includes a cooling pipe 201, a water inlet pipe 202, a water outlet pipe 203 and a connecting valve 204. The upper and lower sides of the cooling pipe 201 are respectively connected and installed with the water inlet pipe 202 and the water outlet pipe 203. At one end of the water inlet pipe 202 and the water outlet pipe 203 away from the cooling pipe 201, a connecting valve 204 is installed. The cooling pipe 201, the water inlet pipe 202 and the water outlet pipe 203 are fixedly sealed and welded. The structures of the water inlet pipe 202 and the water outlet pipe 203 are the same. Through the heat conduction pipe 3, the whole water cooling module 2 is connected to the temperature sensing module 4. After use, through the heat conduction pipe 3, the high temperature contained in the temperature sensing module 4 can be quickly conducted into the water cooling module 2. At this time, only by connecting the water inlet pipe 202 and the water outlet pipe 203 to an external water supply device through the connecting valve 204, cold water can continuously flow inside the cooling pipe 201, so as to quickly conduct away the heat transferred to the whole water cooling module 2 through the heat conduction pipe 3, so as to quickly and continuously dissipate the heat of the temperature sensing module 4, thereby protecting the whole temperature sensing module 4, and improving the safety protection of the whole structure of the sensor itself.

[0025] The connection module 5 includes a control connector 501, a connection jack 502, and a connection solenoid 503. A connection jack 502 is installed on one side of the control connector 501, and a connection solenoid 503 is provided on the side of the connection jack 502 away from the control connector 501. The connection between the connection module 5 and the wire insertion module 6 is a threaded connection, and a thermal conductive silicone grease 7 is filled at the connection between the connection module 5 and the wire insertion module 6. The wire insertion module 6 includes a connection plug 601, a connection thread 602, and a transmission cable 603. A connection thread 602 is provided on the outer surface of the connection plug 601, and a transmission cable 603 is connected to the side of the connection plug 601 away from the connection jack 502. The internal surface structure of the connection solenoid 503 matches the outer surface structure of the connection thread 602, and the transmission cable 603 is a spiral elastic structure. Through the structural setting between the connection solenoid 503 and the connection thread 602, while the connection module 5 and the wire insertion module 6 maintain the convenience of disassembly and assembly, the threaded connection between the two structural parts improves the structural stability and firmness of the connection, avoiding the interruption of the connection between the entire high-temperature sensor and the external monitoring host through the wire insertion module 6 due to external factor interference during use. On the other hand, this split structure also facilitates the independent encapsulation and protection of the device. The filling of the thermal conductive silicone grease 7 can, on the one hand, assist in heat dissipation between the wire insertion module 6 and the connection module 5, and at the same time, it can also play a sealing role to prevent moisture ingress and liquid leakage, thereby avoiding the damage of electronic components.

[0026] The connecting pipe 1, the water cooling module 2, the heat conducting pipe 3, the temperature sensing module 4, and the connection module 5 are all connected and installed on the same horizontal central axis, and the heat conducting pipe 3 and the temperature sensing module 4 are hermetically welded. The temperature sensing module 4 includes a heat preservation and protection pipe 401, a temperature sensing semiconductor 402, and a temperature sensing conductor 403. A temperature sensing semiconductor 402 is installed in the center of the heat preservation and protection pipe 401, and temperature sensing conductors 403 are attached to the upper and lower sides of the temperature sensing semiconductor 402. The heat preservation and protection pipe 401 is made of the commonly used high-temperature ceramic base material ZrO2. This material has good oxidation resistance and corrosion resistance, and can maintain stable performance even in harsh environments. At the same time, because the material processing technology of these ceramics is very mature, it can be used to prepare high-temperature sensors that can work above 1000°C, which has greatly increased the applicable range of the entire sensor and improved the practicality of the device.

[0027] In summary, as Figures 1 to 4As shown, when the ultra-high temperature sensor is in use, first apply thermal grease 7 to the connecting thread 602 provided on the outer surface of the connecting plug 601 and the inner surface of the connecting solenoid 503. Then, dock the connecting plug 601 with the connecting socket 502 in the horizontal direction. Subsequently, screw the connecting plug 601 into the inside of the connecting solenoid 503 by rotating it and insert it into the inside of the connecting plug 601, thereby completing the docking of the connecting module 5 and the wiring module 6;

[0028] Subsequently, connect an external water supply device to the entire water-cooling module 2 through the connection valve 204 at one end of the water inlet pipe 202 and the water outlet pipe 203. At this time, turn on the externally connected monitoring host and start the entire sensor. According to the test requirements, insert the temperature sensing module 4 into the high-temperature liquid to be tested. At this time, the high temperature will be transmitted to the temperature-sensitive semiconductor 402 and the temperature-sensitive conductor 403 through the heat-insulating protection tube 401. The temperature-sensitive semiconductor 402 is clamped between the temperature-sensitive conductors 403 up and down. At this time, the temperature-sensitive semiconductor 402 is similar to an insulator, and electrons are bound and cannot move inside. When the high temperature is transmitted, it is heated by the high temperature. The heat energy will make the electrons inside the temperature-sensitive semiconductor 402 become active and have enough energy to break free from the bondage. Therefore, the number of active electrons can be calculated through the pre-set structural materials and the program controlling the connector 501, and then the measured temperature value can be obtained, and thus the temperature changes at different positions of different test objects can be sensed;

[0029] After use, the high temperature contained in the temperature sensing module 4 can be quickly conducted to the water-cooling module 2 through the heat conduction tube 3. At this time, only by connecting the water inlet pipe 202 and the water outlet pipe 203 to the external water supply device through the connection valve 204, cold water can continuously flow inside the cooling tube 201, thereby quickly conducting away the heat transmitted to the entire water-cooling module 2 through the heat conduction tube 3, so as to quickly and continuously dissipate the heat of the temperature sensing module 4.

Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
