Description

Technical Field

[0001] This application belongs to the technical field of temperature measurement, and particularly relates to a support and protection device for a temperature measurement sensor. Background Art

[0002] A temperature measurement sensor is an electronic component used to measure temperature. As a key component for obtaining temperature information, its accuracy and stability will directly affect the performance of the entire system. Generally, the temperature measurement sensor is held by hand and its front end is brought into contact with the position of the object to be measured to obtain temperature information. The stability of holding by hand and the position of contacting the object will both affect the temperature measurement result.

[0003] When the temperature measurement sensor is in contact with the object to be measured for temperature measurement, in order to ensure the accuracy of the measurement position, if there is no fixed support, it is easy to cause the front end of the temperature measurement sensor to bend, resulting in the temperature measurement sensor not being inserted in place or not being in close contact with the object to be measured, generating a temperature measurement error; in temperature measurement experiments with high requirements for temperature measurement accuracy and response time, it is often necessary to select a thinner temperature measurement sensor to accurately reach the temperature measurement point on the object. When the front end of the temperature measurement sensor is thinner, it is easy to bend and cause damage. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. The components of the embodiments of this application described and illustrated herein can be arranged and designed in various different configurations.

[0036] Therefore, the detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application that is claimed, but merely represents selected embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts fall within the scope of protection of this application.

[0037] In the description of the embodiments of this application, it should also be noted that unless otherwise clearly specified and limited, if the terms "installation", "connection", and "coupling" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] To solve the problems of the prior art, the inventors of this application found in their research that changing the temperature measurement method of the handheld sensor to temperature measurement through a fixed support structure can improve the stability of temperature measurement. At the same time, by adding an elastic structure body to the support structure, the front-end extension length of the temperature measurement sensor can be adjusted and restricted, thereby solving the problem of the front-end bending of the temperature measurement sensor. In this regard, the embodiments of this application provide a temperature measurement sensor support and protection device, which realizes the elastic fixed support of the temperature measurement sensor and at the same time avoids the problem of the front-end bending of the relatively thin temperature measurement sensor. This device can adopt a seal block structure to improve the sealing performance of the device; multiple devices are connected and arranged to improve the temperature measurement efficiency.

[0039] See Figure 1 , a temperature measurement sensor support and protection device provided by the embodiments of this application includes a fixed support structure 2, an elastic structure body 3, and a tightening cap 4;

[0040] The temperature measurement sensor includes a temperature measurement rod 1 and a connection part 5 that are connected to each other; the fixed support structure 2 is stepped along the axial direction and includes a support sleeve cavity 21 and an elastic support cavity 22, and a through hole is opened inside, and the front end of the temperature measurement rod 1 passes through the through hole;

[0041] A boss is formed at the through-hole connection of the support sleeve cavity 21 and the elastic support cavity 22. The elastic structure body 3 is sleeved on the temperature measuring rod 1. One end of the elastic structure body 3 is stuck at the boss, and the other end is stuck at the connecting part 5.

[0042] The tightening cap 4 is fixed to the rear end of the fixed support structure 2 and is used to press the connecting part 5 so that the front end of the temperature measuring rod 1 extends out from the front end of the fixed support structure 2.

[0043] In some possible implementation manners of the embodiment of the present application, the temperature measuring sensor support and protection device further includes an auxiliary positioner 8 and a fixed support leg 9.

[0044] The auxiliary positioner 8 is fixed between the fixed support structure 2 and the tightening cap 4.

[0045] Optionally, the auxiliary positioner 8 is a semi-circular ring structure. Generally, the wall thickness of the ring of the auxiliary positioner 8 is 3-5 mm; the semi-circular ring angle of the auxiliary positioner 8 is 120°-170°.

[0046] The inner diameter of the semi-circular ring of the auxiliary positioner 8 is 0.5-1 mm larger than the outer diameter of the tightening cap 4.

[0047] The outer diameter of the semi-circular ring of the auxiliary positioner 8 is 5-10 mm larger than the outer diameter of the cylindrical body at the tail end of the tightening cap 4, which is convenient for taking out.

[0048] It should be noted that when the temperature measuring sensor is overhauled and replaced and reinstalled, the auxiliary positioner 8 can quantitatively judge the similarity of the insertion depth of the temperature measuring sensor to that before, without the need to recalibrate the position, which is convenient for comparing the accuracy of multiple measurement results, so as to detect faults in time.

[0049] The fixed support leg 9 is fixed to the outer wall surface of the fixed support structure 2 by welding or bolts, and the fixing method can be flexibly selected according to needs.

[0050] Such as Figure 2 and Figure 3 As shown, when fixed by bolts, the bolt holes of the fixed support leg 9 are opened on the bottom surface or the side surface.

[0051] In one example, when there are two fixed support legs 9, the two fixed support legs 9 are arranged on different sides of the fixed support structure 2 and the distances from the front end of the fixed support structure 2 are not equal.

[0052] In another example, when there are two fixed support legs 9, the two fixed support legs 9 are arranged on the same side of the fixed support structure 2.

[0053] It should be noted that by adjusting the height of the fixed support leg 9, the temperature measuring rod 1 can be placed at different positions of the object to be measured, so as to fix the position of the temperature measuring sensor relative to the object to be measured. When measuring again, the original position can be kept unchanged.

[0054] In some possible implementation manners of the embodiments of the present application, the inner diameter of the support sleeve cavity 21 is 0.1-0.2 mm wider than the outer diameter d of the temperature measuring rod 1;

[0055] The inner diameter of the elastic support cavity 22 is 3-6 mm wider than the outer diameter D of the connecting portion 5;

[0056] The chamber length of the elastic support cavity 22 should be 10-35 mm greater than the length of the elastic structure 3 in the uncompressed state.

[0057] It can be understood that the fixed support structure 2 can clamp and limit the temperature measuring sensor under the above dimensions, ensuring the stability of the temperature measuring process of the temperature measuring sensor.

[0058] In some possible implementation manners of the embodiments of the present application, the elastic structure 3 is a compression spring;

[0059] When the outer diameter d of the front end 1 of the temperature measuring sensor is 1-2 mm, the spring wire diameter of the elastic structure 3 is 0.5-0.8 mm; when the outer diameter d of the front end 1 of the temperature measuring sensor is 2-3 mm, the spring wire diameter of the elastic structure 3 is 0.8-1 mm; when the outer diameter d of the front end 1 of the temperature measuring sensor is greater than 3 mm, the spring wire diameter of the elastic structure 3 is greater than 1 mm;

[0060] The inner diameter of the spring of the elastic structure 3 is d + 0.5-1 mm;

[0061] The outer diameter of the spring of the elastic structure 3 is 0.5-1 mm smaller than the inner diameter of the elastic support cavity 22;

[0062] The spring of the elastic structure 3 has 8.5-12.5 turns, preferably 10.5 turns;

[0063] For the working load and other related parameters of the spring of the elastic structure 3, selection can be made with reference to corresponding standards (such as GB / T1973.3, GB / T 2089, etc.).

[0064] It should be noted that the elastic structure 3 has a better elastic support effect under the above parameters.

[0065] In some possible implementation manners of the embodiments of the present application, the bottom of the squeezing cap 4 is provided with an opening, and the lead 6 of the temperature measuring sensor is sleeved in the lead protection layer 7 and led out from the opening at the bottom of the squeezing cap 4;

[0066] The squeezing cap 4 is in a stepped shape with a central hole, and the inner diameter of the central hole is D + 0.3-0.5 mm.

[0067] In some possible implementation manners of the embodiments of the present application, as Figure 4 shown, the temperature measuring sensor support and protection device further includes a pressing block 14 and a sealing block 15;

[0068] The pressing block 14 is located between the sealing block 15 and the elastic structure 3, and the sealing block 15 is stuck at the boss.

[0069] In one example, a chamfered surface is provided on the side of the sealing block 15, an annular groove is provided on the chamfered surface, and a sealing ring is placed in the annular groove.

[0070] In another example, the material of the sealing block 15 is any one of asbestos rubber, polytetrafluoroethylene, silicone rubber, and fluororubber.

[0071] It can be understood that by adding the structures of the sealing block 15 and the pressing block 14, the internal sealing of the fixed support device is realized, providing support for the temperature measuring sensor for measuring the temperature of high-flow and high-impact fluid, and preventing the fluid from entering the temperature measuring sensor support and protection device.

[0072] In some possible implementation manners of the embodiments of the present application, when the temperature measuring sensor is a thermocouple, the temperature measuring rod 1 extends 1-3 mm outside the support sleeve cavity 21;

[0073] When the temperature measuring sensor is a thermal resistor, the temperature measuring rod 1 extends 5-10 mm outside the support sleeve cavity 21.

[0074] It can be understood that by restricting the extension length of the temperature measuring rod according to the type of the temperature measuring sensor, the front end of the temperature measuring sensor can be prevented from being bent due to excessive extension.

[0075] In some possible implementation manners of the embodiments of the present application, as Figure 5 shown, when there are two temperature measuring sensor support and protection devices, the two temperature measuring sensor support and protection devices are connected by fixed support feet 9, and the two fixed support feet 9 are arranged on the same side of the fixed support structure 2 so that the front end positions of the fixed support structures 2 in the two temperature measuring sensor support and protection devices are the same;

[0076] In one example, the fixed support feet 9 of the two temperature measuring sensor support and protection devices are fixed by bolts 10, and the two ends of the bolts 10 are respectively inserted into gaskets 13 and elastic gaskets 12 and tightened by nuts 11;

[0077] When there are more than two temperature measuring sensor support and protection devices, first fix the temperature measuring sensor support and protection device at the outermost edge position, and then fix the remaining temperature measuring sensor support and protection devices inward in turn.

[0078] It can be understood that when multiple temperature measuring sensors are connected and used through support and protection devices, the temperatures at multiple positions can be obtained at one time, improving the temperature measuring efficiency; by changing the length of the fixed support feet 9, the distance between the temperature measuring sensors can be adjusted, so as to fix the relative positions between the multiple temperature measuring sensors. When measuring the temperatures at multiple positions again, the temperature measuring positions can be kept unchanged.

[0079] The following describes the specific assembly method of a temperature measurement sensor support and protection device provided by the embodiments of the present application in combination with specific examples:

[0080] Embodiment 1

[0081] Refer to Figure 1 , the specific assembly method of the above temperature measurement sensor support and protection device is as follows:

[0082] S1. Determine the size parameters of the temperature measurement sensor support and protection device according to the position of the object to be measured, the type of temperature measurement sensor, etc., and complete the processing and manufacturing.

[0083] S2. The fixed foot 9 is fixed to the outer wall surface of the fixed support structure 2 by welding. The material of the fixed foot 9 is the same as that of the fixed support structure 2, which is convenient for welding;

[0084] Optionally, the fixed foot 9 is fixed to the outer wall surface of the fixed support structure 2 by bolts. As Figure 2 shown, the bolt holes of the fixed foot 9 are opened on the bottom surface, or, as Figure 3 shown, the bolt holes of the fixed foot 9 are opened on the side surface;

[0085] Optionally, two fixed feet 9 are provided. The two fixed feet 9 are arranged on the same side or different sides of the fixed support structure 2. When they are on different sides, the distances from the two fixed feet 9 to the front end of the fixed support structure 2 are not equal.

[0086] S3. The elastic structure body 3 is sleeved on the temperature measurement sensor from the temperature measurement rod 1, and one end is stuck at the connecting part 5.

[0087] S4. The temperature measurement rod 1 is inserted into the support sleeve cavity 21 of the fixed support structure 2 until the temperature measurement rod 1 extends out of the support sleeve cavity 21;

[0088] According to the type of temperature measurement sensor, adjust the length of the temperature measurement rod 1 extending out of the support sleeve cavity 21.

[0089] S5. The tightening cap 4 is sleeved from the outside of the connecting lead protection sleeve 7 at the tail of the temperature measurement sensor;

[0090] Rotate the tightening cap 4 so that it is stuck at the interface between the connecting part 5 and the lead protection layer 7, and there should be a gap of slightly more than 5 mm between the rear end face with a larger radial dimension of the tightening cap 4 and the tail end of the elastic support cavity 22 to be able to place the auxiliary locator 8.

[0091] S6. Continue to rotate the tightening cap 4 to compress the elastic structure body 3. At this time, install the auxiliary locator 8 until the auxiliary locator 8 is stuck by the tightening cap 4 and will not fall due to gravity, then stop rotating the tightening cap 4.

[0092] Embodiment 2

[0093] AsFigure 4 As shown, optionally, a sealing block 15 is installed on the temperature measuring sensor support and protection device;

[0094] The sealing block 15 is any one of asbestos rubber, polytetrafluoroethylene, silicone rubber, and fluororubber.

[0095] In order to cooperate with the use of the sealing block 15, a pressing block 14 needs to be installed at the same time;

[0096] The pressing block 14 has a central hole. The inner diameter of the central hole of the pressing block 14 is d + 0.5 to 1 mm; the outer diameter of the pressing block 14 is 0.5 to 1 mm smaller than the inner diameter of the elastic support cavity 22; the thickness of the pressing block 14 is generally 3 to 5 mm.

[0097] When the sealing block 15 is adopted, the wire diameter of the spring of the elastic structure body 3 is 3.5 to 6.0 mm, and the spring of the elastic structure body 3 has 10.5 to 12.5 turns, preferably 12.5 turns;

[0098] At this time, the cavity of the elastic support cavity 22 is extended, and its length should be 10 to 35 mm larger than the sum of the length of the elastic structure body 3 in the uncompressed state, the length of the sealing block 15, and the length of the pressing block 14.

[0099] An arc chamfered surface connection is provided between the support sleeve cavity 21 and the elastic support cavity 22 for cooperating with the chamfered surface of the sealing block 15 to form a sealing structure;

[0100] The arc chamfered surface is provided with an annular groove, and a sealing ring is placed in the annular groove; the sealing ring is a ring with a thickness; the sealing ring is selected according to parameters such as the pressure, medium, and temperature of the use environment, and generally metal wound gaskets, asbestos rubber, polytetrafluoroethylene, silicone rubber, fluororubber and other materials are selected, which can enhance the sealing effect.

[0101] The assembly method of the temperature measuring sensor support and protection device in this embodiment is referred to Example 1. The difference from Example 1 is that:

[0102] After step S3, an additional operation should be added: the pressing block 14 and the sealing block 15 are sequentially sleeved on the temperature measuring sensor from the front end 1 of the temperature measuring sensor, and one end of the pressing block 14 is in contact with the elastic structure body 3.

[0103] The embodiments of the present application have the following beneficial effects:

[0104] (1) It realizes the elastic fixed support of the temperature measuring sensor. When measuring the surface of an object or inserting into a small hole to measure the internal temperature of the object, it ensures that the temperature measuring sensor is in close contact with the object to be measured while avoiding bending at the front end, so as to achieve the effect of accurate temperature measurement.

[0105] (2) It avoids the situation of bending at the front end of the relatively thin temperature measuring sensor and can cope with the situation with high requirements for temperature measurement accuracy and temperature measurement response.

[0106] (3) When the temperature measuring sensor is overhauled or replaced and reinstalled, the auxiliary positioner can quantitatively judge the similarity of the insertion depth of the temperature measuring sensor to that before, without the need to recalibrate the position, which is convenient for comparing the accuracy of multiple measurement results, so as to detect faults in time.

[0107] (4) When the temperature measuring sensor is overhauled or replaced and reinstalled, there is no need to adjust the height of the fixed support feet, and the contact position between the temperature measuring rod and the object to be measured can be kept unchanged; when multiple temperature measuring sensors are connected, the relative positions between the temperature measuring sensors can be kept unchanged, without the need to recalibrate the position, which is convenient for comparing the accuracy of multiple measurement results, so as to detect faults in time.

[0108] (5) The device structure utilizes the structure of the temperature measuring sensor itself, with a simple structure and low cost, applicable to conventional thermocouples, platinum resistors, etc., and has a wide application range.

[0109] (6) The device can be fixed by bolts or welding, and the fixing method can be flexibly selected according to needs.

[0110] (7) Through the sealing block and pressing block structure, the internal sealing of the fixed support device is realized, providing support for the temperature measuring sensor for measuring the temperature of high-flow and high-impact fluids, preventing the fluid from entering the temperature measuring sensor support and protection device, and avoiding damage to the temperature measuring sensor by the fluid impact.

[0111] The above are only the embodiments of the present application and are not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0112] The embodiments of the present application disclosed above are only used to help explain the present application. The optional embodiments do not describe all the details in detail, nor do they limit the present application to the specific implementation manners described. Obviously, many modifications and changes can be made according to the content of the present application.
