Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary temperature measurement, and particularly relates to a jacking shaft type auxiliary temperature measurement device. Background Technique

[0002] An insertion type temperature sensor is a sensor designed to be inserted into a specific environment or device to measure and monitor temperature parameters; in industry, temperature sensors are usually installed on the walls of mechanical equipment such as steam turbines and pumps to measure the temperature of important parts inside the machines, and are connected to instrument displays through wires.

[0003] At present, in actual applications of existing temperature sensors, it is found that due to the long-term contact of the detection probe with the solution and external mechanisms, and being located inside the machine, impurities are extremely likely to remain on the surface of the probe, affecting the temperature measurement accuracy and easily causing damage to the probe, thus affecting its use stability performance.

[0004] To solve the above problems, a jacking shaft type auxiliary temperature measurement device is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a jacking shaft type auxiliary temperature measurement device, which solves the problems raised in the above background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a jacking shaft type auxiliary temperature measurement device, including: a temperature sensor, an induction probe, a shaft seat, and a threaded adapter. A sealing gasket is provided between the threaded adapter and the shaft seat; a spiral blade of a spiral structure surrounds the outside of the induction probe and is used to scrape off impurities on the surface of the induction probe and send them out in a spiral manner. A guide rod is provided inside the shaft seat and is used to drive a turntable inside the shaft seat to rotate. An articulated rod is provided at the upper end of the spiral blade and is docked to the turntable; an outer ring groove is opened on the outside of the shaft seat, and limit seats are installed on the inner sides of its upper and lower ends. Spring type buffers are evenly distributed circumferentially on the outside of the shaft seat and are located between adjacent limit seats to form buffer protection against the vibration of external equipment.

[0008] Further, a support for rotating and installing the protruding mechanism at the upper end of the guide rod is provided on one side inside the shaft seat, and a spring rod for driving the guide rod to slide up and down is provided inside the support.

[0009] Further, an airbag is also provided inside the support to drive the guide rod to rebound, and the spring rod and the airbag are respectively located at the upper and lower ends inside the support.

[0010] Furthermore, the upper and lower ends of the spring-type buffer are provided with protruding elastic balls, which are engaged with the positioning holes on the inner side of the limiting seat, and the elastic balls are used to press against the upper hole wall edge of the positioning hole to fix the spring-type buffer.

[0011] Furthermore, the driving gear shaft meshingly connected with the upper end of the rotating disk is rotatably installed in the positioning groove at the lower end of the shaft seat through the protruding shaft bodies at both ends.

[0012] Furthermore, three shifting plates are provided on one side of the active gear shaft, which drive the active gear shaft to rotate when the support rod at the lower end of the guide rod is pressed against it.

[0013] Furthermore, the spiral blade is also used to remove residual substances on the surface of the sensing probe when it is disassembled and removed, so as to avoid dripping outwards after removal.

[0014] The utility model has the following beneficial effects:

[0015] The utility model uses the vibration of the monitored machine in conjunction with the spring rod and the airbag to keep the guide rod in a long-term up-and-down sliding motion state, and then uses the support rod to move the positioning groove to make the active gear shaft drive the turntable to rotate. At this time, the spiral piece rotates to scrape off the impurities on the outer surface of the sensing probe rod, so that the surface is kept clean, so as to prevent the impurities from remaining for a long time to form dirt, and ensure the accuracy of temperature monitoring;

[0016] The utility model arranges the spring buffer externally by opening an outer ring groove, which can immediately buffer the vibration of the equipment during use to prevent the induction probe rod from swinging and affecting its temperature sensing effect, so that the temperature sensor can adapt to different mechanical equipment and maintain a stable temperature measurement function under vibrating working conditions. Secondly, the external arrangement can also make the assembly and disassembly operations more convenient, which is convenient for subsequent maintenance and other processing and use.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] Please refer to Figures 1-5 As shown, the present utility model is a top-shaft type auxiliary temperature measuring device, including: a temperature sensor 1, an induction probe 2, a shaft seat 4, and a threaded adapter 5. A sealing gasket 10 is provided between the threaded adapter 5 and the shaft seat 4;

[0029] The spiral blade 3 with a spiral structure surrounds the outside of the induction probe 2 and is used to scrape off the impurities on the surface of the induction probe 2 and send them out in a spiral manner. A guide rod 12 is provided inside the shaft seat 4 and is used to drive the turntable 9 inside the shaft seat 4 to rotate. A connecting rod 11 is provided at the upper end of the spiral blade 3 and is connected to the turntable 9;

[0030] An outer ring groove 6 is provided on the outer side of the shaft seat 4, and limit seats 8 are installed on the inner sides of the upper and lower ends thereof. Spring buffers 7 are evenly distributed on the outer circumference of the shaft seat 4 and are located between adjacent limit seats 8 to provide buffer protection against vibration of external equipment.

[0031] The present embodiment provides a temperature monitoring device that can clean the sensing probe 2 in real time. The guide rod 12 is used to drive the spiral blade 3 to rotate, which can not only clean the sensing probe 2, but also send out the scraped impurities in a spiral manner to avoid long-term residual to ensure the subsequent stable sensing accuracy. Secondly, in conjunction with the external spring buffer 7, the vibration buffer generated by the mechanical equipment can also be decomposed in the first time to prevent it from directly acting on the sensing probe 2, thereby ensuring its stable working state.

[0032] Among them, a support 13 for rotatably mounting the upper protruding mechanism of the guide rod 12 is provided on one side of the inner part of the shaft seat 4, and a spring rod 14 for driving the guide rod 12 to slide up and down is provided inside the support 13, and an air bag 15 is also provided inside the support 13 to drive the guide rod 12 to rebound, and the spring rod 14 and the air bag 15 are respectively located at the upper and lower ends of the inner part of the support 13, so that the guide rod 12 is in a state of frequent up and down sliding movement to maintain the use state of the spiral piece 3.

[0033] Among them, the upper and lower ends of the spring buffer 7 are provided with protruding elastic balls 16, which are engaged with the positioning hole 17 on the inner side of the limit seat 8. The elastic ball 16 is used to press against the upper hole wall edge of the positioning hole 17 to fix the spring buffer 7. Through the elastic deformation characteristics of the elastic ball 16, it can be directly inserted into the interior of the positioning hole 17, and automatically reset when passing through to press against the hole wall edge position of the positioning hole 17.

[0034] Among them, the active gear shaft 18 meshingly connected with the upper end of the turntable 9 is rotatably installed in the positioning groove 21 at the lower end of the shaft seat 4 through the protruding shafts at both ends.

[0035] The spiral blade 3 is also used to remove residual substances on the surface of the sensing probe 2 when it is disassembled and removed, so as to prevent it from dripping outward after being taken out.

[0036] It can be understood that the utility model can clean the surface of the probe rod in real time to prevent impurities from remaining for a long time to form dirt, ensure the data accuracy during temperature monitoring, and secondly, can timely buffer mechanical vibration during use, so that the probe rod maintains a stable use state.

[0037] A specific application of the operation process of this embodiment is as follows: when in use, firstly, the external spring buffer 7 is used to form a buffer protection in the first time when the mechanical equipment vibrates, so as to prevent the vibration from being transmitted to the sensing probe 2, so that it maintains a stable temperature measurement working state; secondly, the spring buffer 7 can be conveniently assembled and disassembled by using the snap connection between the elastic ball 16 and the positioning hole 17, so as to facilitate maintenance and replacement operations; at the same time, the spring rod 14 and the airbag 15 are used to cooperate with each other to drive the guide rod 12 to slide up and down frequently under the action of the vibration aftershock, and then the support rod 19 at its lower end is used to resist the dial plate 20 to make it swing, and then the active gear shaft 18 is used to engage with the turntable 9 to drive the spiral piece 3 to rotate, and the impurities on the surface of the sensing probe 2 are spirally removed to prevent the impurities from remaining for a long time to form dirt, so as to ensure the temperature measurement accuracy during use.
