Description

Technical Field

[0001] This utility model relates to the field of sensor repair, and in particular to a device for disassembling the rear cover of a thermal control sensor. Background Technology

[0002] Thermal power plants, solar thermal power plants, and other industrial site systems are complex, resulting in a large number of thermal control instruments. These include temperature sensors such as resistance temperature detectors (RTDs) and thermocouples; pressure sensors such as pressure transmitters and differential pressure transmitters; and flow and level sensors such as ultrasonic flow meters and radar level gauges. All of these sensor housings are made of aluminum alloy to ensure heat dissipation and meet IP65 waterproof requirements. All sensors are designed with a cover after wiring for easy installation, wiring, and maintenance. The cover is designed to be waterproof, therefore using a small-pitch thread to connect to the sensor body.

[0003] Thermal power plants and solar thermal power plants are located in northwestern and southern provinces. Due to the harsh climate and frequent sandstorms in the northwestern provinces, the rear cover of the aforementioned sensors is frequently disassembled and installed during maintenance. Excessive sand and dust accumulates in the threads of the rear cover, making it impossible to rotate and disassemble it by hand, thus affecting the efficiency of maintenance work and the reliability of the equipment.

[0004] Similarly, in southern provinces, due to the humid environment, dirt on the threads of the sensor's rear cover can accumulate and form scale after prolonged contact with moisture in the air, making it impossible to rotate and disassemble the sensor's rear cover normally.

[0005] Maintenance personnel can only disassemble the equipment by force. After disassembly, the instrument body can no longer meet the original waterproof performance, which leads to a reduction in equipment reliability and lifespan. Forced disassembly can also damage the equipment or require the replacement of the entire sensor, thereby increasing production costs. Utility Model Content

[0006] This utility model provides a device for disassembling the rear cover of a thermal control sensor, which solves the problems of frequent disassembly and installation of the sensor's rear cover in harsh climates and windy, sandy weather, where excessive sand and dust accumulate in the threads of the rear cover, making it impossible to disassemble by hand, thus affecting maintenance efficiency and equipment reliability; and in humid environments, dirt on the threads of the sensor's rear cover forms scale after prolonged contact with moisture in the air, making it impossible to rotate and disassemble normally.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for disassembling the rear cover of a thermal control sensor, including a housing, an outer ring on the housing, a rotating adjusting gear ring at the bottom of the outer ring, multiple meshing gears on the adjusting gear ring, multiple telescopic clamping pins on the outer ring, the clamping pins meshing with the gears, and a limiting ring inside the outer ring, the clamping pins sliding against the limiting ring.

[0008] In a preferred embodiment, the outer shell includes a hollow annular shell with multiple flat-bottomed holes on the inner wall and an arc-shaped groove and multiple circumferentially arrayed first through grooves on the outer wall.

[0009] In the preferred embodiment, the housing is provided with a gripping rod, and the cross-section of the first through groove is an L-shaped structure.

[0010] In the preferred embodiment, the outer ring includes an outer ring body, the bottom of which is provided with an annular groove, and the outer ring body is provided with a plurality of second through grooves arranged in a circumferential array. The outer ring is installed inside the outer shell, and the cross-section of the second through groove is an L-shaped structure.

[0011] In the preferred embodiment, the adjusting gear ring includes an internal gear ring, a slip ring is provided at the top of the internal gear ring, the slip ring slides against the ring groove, a handle is provided on the internal gear ring, the handle slides against the arc groove, and the internal gear ring meshes with multiple gears.

[0012] In the preferred embodiment, the limiting ring is installed inside the housing, and the limiting ring is provided with multiple circumferentially arrayed third through slots, the cross-section of which is an L-shaped structure.

[0013] In the preferred embodiment, the clamping pin includes a bottom slider, a rack on one side of the bottom slider that meshes with a gear, a column at one end of the bottom slider, and a mounting plate on the column.

[0014] In the preferred embodiment, the bottom slider abuts against the first through groove, the second through groove and the third through groove in sequence, and a spring is provided between the mounting plate and the limiting ring.

[0015] In the preferred embodiment, the gear is rotatably connected to the housing.

[0016] The beneficial effects of this utility model are as follows: When it is necessary to install or remove the rear housing of the sensor, the outer shell is moved so that the rear housing of the sensor is located inside the outer shell. The operator holds the grip lever with one hand and the handle with the other hand, and rotates the handle to make the adjusting gear ring inside the outer shell rotate, so that multiple gears rotate simultaneously, so that multiple clamping pins slide relative to the outer ring, so that the multiple clamping pins are equivalent to opening and closing the rear housing of the sensor, so that one end of the column of the multiple clamping pins abuts against the rear housing of the sensor. Pushing the handle makes the multiple clamping pins tightly clamp the rear housing of the sensor. Pushing the handle at the same time pushes the grip lever, so that the entire device clamps the rear housing of the sensor and rotates, so as to install or remove the rear housing of the sensor.

[0017] The overall structure uses a rotating handle to open and close multiple clamping pins. The handle, acting as a power arm, is relatively long, generating significant torque with minimal force to easily tighten fasteners, reducing operational intensity and achieving a labor-saving effect. Simultaneous rotation of the grip bar and handle allows for the installation or removal of the sensor's rear cover, enabling safe and labor-saving disassembly of various thermal control sensor rear covers. This improves maintenance efficiency, extends equipment lifespan, enhances equipment reliability, and contributes to the safe and stable operation of generator sets. It also prevents excessive sand and dust accumulation in the sensor's rear cover during windy and sandy weather, or scale buildup due to prolonged contact with moisture in humid environments, which can hinder normal rotation and disassembly.

Detailed Implementation

[0027] Example 1:

[0028] like Figure 1-7In the middle, a device for disassembling the rear cover of a thermal control sensor includes a housing 1, an outer ring 2 on the housing 1, a rotating adjusting gear ring 3 at the bottom of the outer ring 2, multiple meshing gears 6 on the adjusting gear ring 3, multiple telescopic clamping pins 5 on the outer ring 2, the clamping pins 5 meshing with the gears 6, and a limiting ring 4 inside the outer ring 2, the clamping pins 5 sliding against the limiting ring 4. With this structure, when it is necessary to install or remove the rear housing of the sensor, the outer casing 1 is moved so that the rear housing of the sensor is located inside the outer casing 1. The operator holds the grip lever 105 with one hand and the handle 303 with the other hand, and rotates the handle 303 to rotate the adjusting gear ring 3 inside the outer casing 1. This causes multiple gears 6 to rotate simultaneously, causing multiple clamping pins 5 to slide relative to the outer ring 2. This allows the multiple clamping pins 5 to open and close the rear housing of the sensor, so that one end of the column 504 of the multiple clamping pins 5 abuts against the rear housing of the sensor. Pushing the handle 303 causes the multiple clamping pins 5 to clamp the rear housing of the sensor tightly. Pushing the handle 303 at the same time pushes the grip lever 105, causing the entire device to clamp the rear housing of the sensor and rotate, so as to install or remove the rear housing of the sensor.

[0029] The overall structure utilizes the rotation of handle 303 to open and close multiple clamping pins 5. Handle 303 acts as a power arm; its relatively long length allows for the generation of significant torque with minimal force, easily tightening fasteners and reducing operational intensity, thus achieving a labor-saving effect. Simultaneous rotation of the grip bar 105 and handle 303 enables the installation or removal of the sensor's rear cover, facilitating the safe and labor-saving disassembly of various thermal control sensor rear covers. This improves maintenance efficiency, extends equipment lifespan, enhances equipment reliability, and contributes to the safe and stable operation of the generator set. It also prevents excessive sand and dust accumulation in the sensor's rear cover during windy and sandy weather, or scale buildup due to prolonged contact with moisture in humid environments, which can hinder normal rotation and disassembly.

[0030] Multiple springs 7 are provided between the clamping pin 5 and the limiting ring 4. The springs 7 have a small elastic force. When the whole device is not in use, the springs 7 will cause the adjusting toothed ring 3 to slowly return to its original position, while preventing the clamping pin 5 from falling off the outer shell 1 or the outer ring 2, thus protecting the clamping pin 5.

[0031] In a preferred embodiment, the outer shell 1 includes a hollow annular shell 101. The inner wall of the annular shell 101 has a plurality of flat-bottomed holes 103, and the outer wall of the annular shell 101 has an arc-shaped groove 104 and a plurality of circumferentially arranged first through slots 102. With this structure,

[0032] In the preferred embodiment, the housing 101 is provided with a gripping rod 105, and the cross-section of the first through groove 102 is L-shaped. With this structure,

[0033] In the preferred embodiment, the outer ring 2 includes an outer ring body 201, with an annular groove 202 at its bottom and multiple circumferentially arrayed second through grooves 203. The outer ring 2 is installed inside the outer casing 1, and the cross-section of the second through grooves 203 is L-shaped. With this structure, the outer ring 2 is installed at the top inside the outer casing 1, and the adjusting gear ring 3 is installed at the bottom inside the outer casing 1. The adjusting gear ring 3 is rotatably connected to the outer ring 2, allowing it to rotate relative to the outer casing 1.

[0034] In the preferred embodiment, the adjusting gear ring 3 includes an inner gear ring 301, with a slip ring 302 at its top. The slip ring 302 slides against the annular groove 202. A handle 303 is provided on the inner gear ring 301, and the handle 303 slides against the arc-shaped groove 104. The inner gear ring 301 meshes with multiple gears 6. With this structure, the cross-sections of the slip ring 302 and the annular groove 202 are L-shaped, allowing the slip ring 302 to slide against the annular groove 202. The top of the gears 6 meshes with the rack 502, and the bottom of the gears 6 meshes with the inner gear ring 301.

[0035] In the preferred embodiment, the limiting ring 4 is installed inside the outer casing 1, and the limiting ring 4 has a plurality of circumferentially arrayed third through grooves 401, the cross-section of the third through grooves 401 being an L-shaped structure. Due to this structure, the bottom slider 501 has an L-shaped cross-section, allowing the bottom slider 501 to sequentially pass through the first through groove 102, the second through groove 203, and the third through groove 401.

[0036] In the preferred embodiment, the clamping pin 5 includes a bottom slider 501, a rack 502 on one side of the bottom slider 501, the rack 502 meshing with the gear 6, and a column 504 at one end of the bottom slider 501, on which a mounting plate 503 is provided. With this structure, when it is necessary to install or remove the rear housing of the sensor, move the outer shell 1 so that the rear housing of the sensor is located inside the outer shell 1. The operator holds the grip lever 105 with one hand and the handle 303 with the other hand, and rotates the handle 303 to make the adjusting gear ring 3 inside the outer shell 1 rotate, so that multiple gears 6 rotate simultaneously, so that multiple clamping pins 5 slide relative to the outer ring 2, so that the multiple clamping pins 5 are equivalent to opening and closing the rear housing of the sensor, so that one end of the column 504 of the multiple clamping pins 5 abuts against the rear housing of the sensor. Push the handle 303 to make the multiple clamping pins 5 tightly clamp the rear housing of the sensor. Pushing the handle 303 at the same time pushes the grip lever 105, so that the whole device clamps the rear housing of the sensor and rotates to install or remove the rear housing of the sensor.

[0037] In the preferred embodiment, the bottom slider 501 abuts against the first through groove 102, the second through groove 203, and the third through groove 401 in sequence. A spring 7 is provided between the mounting plate 503 and the limiting ring 4. Multiple springs 7 are provided between the clamping pin 5 and the limiting ring 4. The spring force of the springs 7 is small. When the whole device is not in use, the springs 7 cause the adjusting toothed ring 3 to slowly return to its original position, while preventing the clamping pin 5 from falling off the outer shell 1 or the outer ring 2, thus protecting the clamping pin 5.

[0038] In the preferred embodiment, gear 6 is rotatably connected to housing 1. With this structure, housing 1 contains multiple rotating shafts, which are connected to gear 6, thus enabling gear 6 to be rotatably connected to housing 1.
