Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and more specifically, to a temperature sensor protection device used downhole in oil and gas wells. Background Technology

[0002] Downhole temperature sensors for oil and gas wells are detection devices specifically designed for high-temperature, high-pressure, and highly corrosive downhole environments. They typically employ high-temperature resistant thermocouples, resistance temperature detectors (RTDs), or semiconductor thermistors, with housings made of corrosion-resistant materials such as Hastelloy. Equipped with armored protective sleeves or thermal insulation structures, they can stably measure formation temperatures in environments reaching hundreds of degrees Celsius, providing data support for oil and gas extraction.

[0003] Publication No. (CN221506004U) discloses a protective device for a temperature sensor, including a base, an mounting plate mounted on the upper end of the base, a temperature sensor body mounted on the upper end of the mounting plate, and a temperature sensor body and the mounting plate being fixedly connected by a temperature sensor fixing mechanism. A protective shell is mounted on the upper end of the mounting plate. This utility model, by setting a temperature sensor fixing mechanism, allows clamping plates one and two to be moved closer together by rotating a handle, thereby facilitating the fixing of the temperature sensor body. At the same time, it ensures that the temperature sensor body will not sway left and right inside the protective shell during use. This utility model, by setting a protective shell fixing mechanism, facilitates the installation of the protective shell on the upper end of the mounting plate, and after fixing, it is also easy to remove the protective shell for maintenance of the temperature sensor body.

[0004] However, this type of protection device for temperature sensors has the following drawbacks: when the temperature sensor needs to be adjusted to a suitable position for detection, it cannot protect the temperature sensor and adjust its position while satisfying the requirements of disassembly and installation. The inability to adjust the position means that the sensor can only detect the temperature of a part of the area, which will cause the area misalignment and result in inaccurate detection results. When vibration occurs, it cannot buffer the vibration, so the sensor will be affected by the vibration. Over time, the temperature sensor will be damaged, resulting in inaccurate detection results. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a temperature sensor protection device for use in oil and gas wells, so as to solve the problem of protecting the temperature sensor and adjusting its position in the prior art while meeting the requirements of disassembly and installation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a temperature sensor protection device used downhole in oil and gas wells, comprising...

[0007] The sensor body is composed of a locking block and a sensor block. A retaining ring is fixedly connected to the outside of the locking block. A pressure ring is slidably connected to the inner wall of the retaining ring. Multiple elastic elements are fixedly connected to the outside of the pressure ring. An arc-shaped ring is fixedly connected to the end of the pressure ring away from the elastic elements. Two connecting plates are fixedly connected to the outside of the locking block. A second locking block is detachably connected to the outside of the two connecting plates. Two pressure plates are slidably connected to the inner wall of the second locking block. A locking plate is fixedly connected to the outside of each of the two pressure plates. An elastic element is fixedly connected to the outside of each pressure plate.

[0008] Two gaskets are fixedly connected to the end of the arc-shaped ring away from the pressure ring. The inner wall of the connecting plate has multiple slots, the outer side of the card plate has a V-shaped groove, the inner wall of the second card block has a sliding groove, and the inner wall of the second card block has a connecting groove.

[0009] The connecting plate is slidably connected to the inner wall of the connecting groove. The inner wall of the second locking block is slidably connected to a top plate. The top plate is fixedly connected to a pressure block. An elastic element three is fixedly connected to the end of the top plate away from the pressure block.

[0010] The outer side of the arc-shaped ring is slidably connected to the inner wall of the retaining ring, and one end of the elastic element away from the pressure ring is fixedly connected to the inner wall of the pressure ring.

[0011] The outer part of the card plate is snapped onto the inner wall of the connecting plate, and the outer part of the card plate is slidably connected to the inner wall of the second card block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In the above scheme, by engaging or disengaging the card plate from the inside of the connecting plate, the sensor body can be adjusted. At the same time, when the first and second card blocks are installed in the oil and gas pipeline, the arc-shaped ring compresses the elastic element 1 through the pressure ring, and the elastic element 1 stores potential energy. This allows the vibration of the oil and gas pipeline to be buffered by the elastic element 1, preventing the sensor body from being affected by vibration and protecting the sensor body. This also prevents deviations during temperature detection and extends the service life of the sensor body. Attached Figure Description

Detailed Implementation

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a temperature sensor protection device for use in oil and gas wells, comprising a locking block 1 and a sensor body 2. A retaining ring 3 is fixedly connected to the outside of the locking block 1. A pressure ring 4 is slidably connected to the inner wall of the retaining ring 3. Multiple elastic elements 6 are fixedly connected to the outside of the pressure ring 4. An arc-shaped ring 5 is fixedly connected to the end of the pressure ring 4 away from the elastic elements 6. Two connecting plates 8 are fixedly connected to the outside of the locking block 1. A locking block 10 is detachably connected to the outside of the two connecting plates 8. Two pressure plates 11 are slidably connected to the inner wall of the locking block 10. A locking plate 12 is fixedly connected to the outside of each of the two pressure plates 11. An elastic element 2 13 is fixedly connected to the outside of the pressure plates 11. The outside of the arc-shaped ring 5 is slidably connected to the inner wall of the retaining ring 3. The end of the elastic element 6 away from the pressure ring 4 is fixedly connected to the inner wall of the pressure ring 4. The outside of the locking plate 12 is locked to the inner wall of the connecting plate 8. The outside of the locking plate 12 is slidably connected to the inner wall of the locking block 10.

[0026] The elastic element 6 is compressed by the pressure ring 4, which allows the elastic element 6 to store potential energy. At the same time, the locking block 1 and the locking block 2 10 are fixedly installed on the outside of the oil and gas pipeline. When the oil and gas pipeline vibrates, the elastic element 6 can buffer the vibration and prevent it from acting on the sensor body 2, making the sensor body 2 more accurate when performing temperature detection. When the sensor body 2 is adjusted, the locking plate 12 is compressed by the pressure plate 11, which causes the locking plate 12 to leave the inside of the connecting plate 8 and no longer lock. In this way, the sensor body 2 can be adjusted.

[0027] Example 2: Based on Example 1, in order to buffer the vibration caused by the oil and gas pipeline, two gaskets 7 are fixedly connected to the end of the arc ring 5 away from the pressure ring 4. Multiple slots 9 are opened on the inner wall of the connecting plate 8. A V-shaped groove 18 is opened on the outer side of the clamping plate 12. A sliding groove 17 is opened on the inner wall of the second clamping block 10. A connecting groove 19 is opened on the inner wall of the second clamping block 10. The end of the clamping plate 12 away from the pressure plate 11 is clamped to the inner wall of the slot 9. The outer side of the connecting plate 8 is slidably connected to the inner wall of the connecting groove 19.

[0028] When the first and second clamps 10 are fixed to the outside of the oil and gas pipeline, the gasket 7 will contact the outside of the oil and gas pipeline and squeeze it, causing the arc ring 5 to squeeze the elastic element 6 through the pressure ring 4. While being squeezed, the elastic element 6 will contract and store potential energy. When the oil and gas pipeline vibrates, the elastic element 6 will buffer the vibration, prevent the sensor body 2 from being affected by the vibration, prevent deviation during temperature detection, and extend the service life of the sensor body 2.

[0029] Example 3: Based on Example 2, in order to facilitate the movement of the card plate 12, the outer side of the connecting plate 8 is slidably connected to the inner wall of the connecting groove 19, the inner wall of the second card block 10 is slidably connected to the top plate 14, the outer side of the top plate 14 is fixedly connected to the pressure block 15, the end of the top plate 14 away from the pressure block 15 is fixedly connected to the elastic element 16, the outer side of the top plate 14 is slidably connected to the inner wall of the slide groove 17, the end of the elastic element 16 away from the top plate 14 is fixedly connected to the inner wall of the slide groove 17, the outer side of the pressure block 15 is slidably connected to the inner wall of the V-groove 18, and the end of the elastic element 13 away from the pressure plate 11 is fixedly connected to the inner wall of the second card block 10.

[0030] By pressing the pressure block 15, the top plate 14 squeezes the elastic element 16. The elastic element 16 releases space, allowing the top plate 14 to slide along the inside of the slide groove 17. The pressure block 15 slides inside the V-shaped groove 18 in the clamping plate 12. Since the contact between the V-shaped groove 18 and the pressure block 15 is V-shaped, when the pressure block 15 slides inside the V-shaped groove 18, the clamping plate 12 squeezes the elastic element 13 through the pressure plate 11, causing the elastic element 13 to deform and release space, so that the clamping plate 12 leaves the inside of the clamping groove 9 in the connecting plate 8 and no longer engages. In this way, the clamping blocks 1 and 2 can be adjusted outside the oil and gas pipeline.

[0031] The working process of this utility model is as follows:

[0032] First, by pressing the pressure block 15, the top plate 14 compresses the elastic element 16. The elastic element 16 releases space, allowing the top plate 14 to slide along the inside of the groove 17. The pressure block 15 slides inside the V-groove 18 in the clamping plate 12. Because the contact between the V-groove 18 and the pressure block 15 is V-shaped, when the pressure block 15 slides inside the V-groove 18, it causes the clamping plate 12 to compress the elastic element 13 via the pressure plate 11. This causes the elastic element 13 to deform and release space, allowing the clamping plate 12 to leave the inside of the groove 9 in the connecting plate 8 and cease further movement. The locking mechanism allows for adjustment of locking blocks 1 and 2 outside the oil and gas pipeline. When locking blocks 1 and 2 are fixed to the outside of the oil and gas pipeline, the gasket 7 contacts the outside of the pipeline and compresses it, causing the arc-shaped ring 5 to compress the elastic element 6 through the pressure ring 4. While being compressed, the elastic element 6 contracts and stores potential energy. When vibration occurs in the oil and gas pipeline, the elastic element 6 will buffer the vibration, preventing the sensor body 2 from being affected by vibration and preventing deviations during temperature detection, while also extending the service life of the sensor body 2.
