Description

Technical Field

[0001] This utility model relates to the field of pipeline temperature measurement technology, specifically a novel digital pipeline thermometer. Background Technology

[0002] A pipeline digital thermometer is a device specifically designed to measure the temperature inside a pipeline. It combines digital display technology with temperature sensing technology to provide accurate and reliable temperature readings. Pipeline digital thermometers are widely used in various industrial fields, such as petroleum, chemical, power, and metallurgy. In these fields, temperature changes inside the pipeline are crucial to the production process, thus requiring the use of high-precision thermometers for monitoring.

[0003] Existing digital pipe thermometers mainly rely on their internal temperature sensors, which can be thermocouples, thermistors, or other digital temperature sensors. They measure temperature through different physical effects or chemical reactions and convert the measured temperature data into electrical signals. These electrical signals are then processed by a microprocessor and converted into digital displays on the screen. At the same time, with the assistance of external wires or other winding devices, the length of the temperature sensing wire can be adjusted. After the digital pipe thermometer is installed, the additional external winding devices are not easy to place, which increases the workload of the installers and makes it difficult to coordinate the probe and control compartment, affecting the ease of use of the probe. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of digital pipeline thermometer that can quickly retract and extend the temperature sensing wire without the need for external retraction equipment, greatly improving the ease of use of the probe and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel pipeline digital thermometer, comprising a digital compartment, a temperature sensing wire at the lower end of the digital compartment, a probe at the lower end of the temperature sensing wire, and a coiling mechanism.

[0006] The retraction mechanism includes a fixed ring, an arc-shaped seat, a rotating shaft, a limiting handle, a fixing rod, and a rubber tube. The fixed rings are fixedly connected to the front end and the middle of the outer surface of the digital compartment, respectively. An arc-shaped seat is fixedly connected between the two fixed rings. The temperature sensing wire is wound around the outer surface of the arc-shaped seat. The upper end of each fixed ring is rotatably connected to a rotating shaft. A limiting handle is fixedly connected to the opposite end of each of the two rotating shafts. A fixing rod is fixedly connected to the end of each limiting handle near the arc-shaped seat. A rubber tube is fixedly connected to the middle of each fixing rod. The rubber tube is installed in conjunction with the temperature sensing wire. This mechanism enables the rapid retraction and extension of the temperature sensing wire without the need for external retraction equipment, greatly improving the ease of use of the probe.

[0007] Furthermore, the retraction mechanism also includes torsion springs, which are all fixedly connected between the limiting handle and the longitudinally adjacent fixed rings. The torsion springs are all movably sleeved on the outer surface of the radially adjacent rotating shafts, so as to limit the temperature sensing wire of the rubber cylinder through the driving force.

[0008] Furthermore, the digital compartment is internally fixedly connected to a partition, and a controller is installed at the lower end of the rear surface of the partition. The input terminal of the controller is electrically connected to an external power source to control various electrical components.

[0009] Furthermore, a temperature sensor is provided at the upper end of the rear surface of the partition, and an analog-to-digital converter is provided at the upper end of the rear surface of the partition. The input end of the temperature sensor is electrically connected to the output end of the temperature sensing wire, the input end of the temperature sensor is electrically connected to the output end of the controller, the output end of the temperature sensor is electrically connected to the input end of the analog-to-digital converter, the analog-to-digital converter is bidirectionally electrically connected to the controller, and the input end of the temperature sensing wire is electrically connected to the output end of the probe through a terminal block, thereby realizing the measurement of the fluid temperature inside the pipe.

[0010] Furthermore, a display cylinder is threadedly connected to the front end of the digital compartment, and a panel is fixedly connected to the front end of the display cylinder. A display screen is provided at the upper end of the panel, and a keypad is provided at the lower end of the panel. Both the display screen and the keypad are bidirectionally electrically connected to the controller to display the temperature of the fluid inside the pipeline.

[0011] Furthermore, a lithium battery is provided at the left end of the front surface of the partition, and the output end of the lithium battery is electrically connected to the input end of the controller. A speaker is provided at the right end of the front surface of the partition, and the input end of the speaker is electrically connected to the output end of the controller. In special circumstances, it powers the digital thermometer and issues an alarm.

[0012] Furthermore, a mounting cylinder is provided at the rear end of the inner surface of the digital compartment, and ribs are fixedly connected to both the upper and lower ends of the outer surface of the mounting cylinder. Symmetrically distributed rib grooves are provided at the rear end of the inner surface of the digital compartment, and the rib grooves are slidably connected to the radially adjacent ribs. Symmetrically distributed screws are threadedly connected between the digital compartment and the mounting cylinder. A mounting plate is fixedly connected to the rear end of the mounting cylinder, and the interior of the mounting plate is provided with uniformly distributed mounting holes to realize the rapid installation of the pipeline digital thermometer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel digital pipeline thermometer has the following advantages:

[0014] Without the need for external winding equipment, the two fixing rings and the arc-shaped seat form a winch. The temperature-sensing guide is manually wound into the inside of the winch. At the same time, under the action of the corresponding torsion spring, the outer wall of the rubber tube contacts the temperature-sensing wire, thereby limiting the temperature-sensing wire and achieving the effect of rapid and stable winding and unwinding of the temperature-sensing wire, which greatly improves the ease of use of the probe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a novel pipeline digital thermometer, including a digital compartment 1, a temperature sensing wire 9 is provided at the lower end of the digital compartment 1, a probe 11 is provided at the lower end of the temperature sensing wire 9 through a terminal block 10, and also includes a coiling mechanism 3;

[0022] The retraction mechanism 3 includes a fixing ring 31, an arc-shaped seat 32, a rotating shaft 33, a limiting handle 34, a fixing rod 36, and a rubber cylinder 37. The fixing rings 31 are fixedly connected to the front end and the middle of the outer surface of the digital compartment 1, respectively. An arc-shaped seat 32 is fixedly connected between the two fixing rings 31. The temperature sensing wire 9 is wound around the outer surface of the arc-shaped seat 32 (the inner end of the temperature sensing wire 9 passes through the rear fixing ring 31 and the digital compartment 1 and is connected to the contact of the temperature sensor 8). The upper ends of the fixing rings 31 are all rotated. The mechanism 3 is connected by rotating shafts 33. Each of the two rotating shafts 33 has a limiting handle 34 fixedly connected to one end facing away from the other. Each limiting handle 34 has a fixing rod 36 fixedly connected to one end near the arc-shaped seat 32. Each fixing rod 36 has a rubber cylinder 37 fixedly connected to its middle section. The rubber cylinders 37 are installed in conjunction with the temperature-sensing wire 9. The retraction mechanism 3 also includes torsion springs 35. Each torsion spring 35 is fixedly connected between the limiting handle 34 and the longitudinally adjacent fixing ring 31. Each torsion spring 35 is movably sleeved on the outer surface of the radially adjacent rotating shafts 33. When the fixing rod 36 is moved away from the center of the digital compartment 1, the fixing rod 36 drives the corresponding limiting handle 34 to move away from the center of the digital compartment 1 around the central axis of the radially adjacent rotating shaft 33. This causes the torsion spring 35 to hold the force. When the rubber cylinder 37 is separated from the temperature sensing wire 9 to a certain distance, the temperature sensing wire 9 is rotated to release it. When the temperature sensing wire 9 is released to the required length, the fixing rod 36 is stopped. The elastic force of the torsion spring 35 acts on the corresponding limiting handle 34. The limiting handle 34 rotates towards the center of the digital compartment 1 around the central axis of the radially adjacent rotating shaft 33. This causes the fixing rod 36 to move towards the center of the digital compartment 1 around the central axis of the radially adjacent rotating shaft 33. The movement of the fixing rod 36 drives the longitudinally adjacent rubber cylinder 37 to move towards the center of the digital compartment 1. The outer surface of the rubber cylinder 37 re-contacts the temperature sensing wire 9 between the fixing ring 31, thus limiting the unreleased temperature sensing wire 9.

[0023] Among them: a partition 2 is fixedly connected inside the digital compartment 1, and a controller 6 is set at the lower end of the rear surface of the partition 2. The input end of the controller 6 is electrically connected to an external power supply.

[0024] Wherein: A temperature sensor 8 is provided at the upper end of the rear surface of the partition 2, and an analog-to-digital converter 7 is provided at the upper end of the rear surface of the partition 2. The input end of the temperature sensor 8 is electrically connected to the output end of the temperature sensing wire 9, the input end of the temperature sensor 8 is electrically connected to the output end of the controller 6, the output end of the temperature sensor 8 is electrically connected to the input end of the analog-to-digital converter 7, the analog-to-digital converter 7 is bidirectionally electrically connected to the controller 6, the input end of the temperature sensing wire 9 is electrically connected to the output end of the probe 11 through the terminal block 10, the probe 11 is installed inside the high-pressure pipeline through the terminal block 10, and then the controller 6 realizes the operation of the analog-to-digital converter 7 and the temperature sensor 8. The probe 11 collects the fluid temperature information inside the high-pressure pipeline and transmits the collected temperature analog information to the signal receiving end of the temperature sensor 8 through the temperature sensing wire 9. The temperature sensor 8 transmits the temperature analog signal to the signal receiving end of the analog-to-digital converter 7. The analog-to-digital converter 7 converts the temperature analog signal into a digital signal and transmits the digital signal to the signal receiving end of the controller 6.

[0025] The digital compartment 1 is threadedly connected to a display cylinder 4, and a panel 5 is fixedly connected to the front end of the display cylinder 4. A display screen 13 is provided at the upper end of the panel 5, and a keypad 14 is provided at the lower end of the panel 5. Both the display screen 13 and the keypad 14 are bidirectionally electrically connected to the controller 6. The controller 6 enables the display screen 13 to operate and display the temperature in real time. The controller 6 issues commands to the controller 6 through the keypad 14 to control the working status of the entire pipeline digital thermometer.

[0026] Wherein: A lithium battery 12 is provided on the left end of the front surface of the partition 2, and the output end of the lithium battery 12 is electrically connected to the input end of the controller 6. A speaker 15 is provided on the right end of the front surface of the partition 2, and the input end of the speaker 15 is electrically connected to the output end of the controller 6. When the temperature value exceeds the standard, the controller 6 enables the speaker 15 to operate and the speaker 15 will sound an alarm. When an external power interruption occurs, the lithium battery 12 supplies power to the controller 6 to ensure the normal operation of the pipeline digital thermometer.

[0027] The digital compartment 1 has a mounting cylinder 16 at its rear end on its inner surface. Ribs are fixedly connected to both the upper and lower ends of the outer surface of the mounting cylinder 16. Symmetrically distributed rib grooves are provided at the rear end of the inner surface of the digital compartment 1. The rib grooves are slidably connected to the radially adjacent ribs. Symmetrically distributed screws 17 are threaded between the digital compartment 1 and the mounting cylinder 16. A mounting plate 18 is fixedly connected to the rear end of the mounting cylinder 16. The mounting plate 18 has evenly distributed mounting holes inside. The mounting cylinder 16 is inserted into the rear end of the digital compartment 1. The ribs at both the upper and lower ends of the mounting cylinder 16 slide inside the corresponding rib grooves, providing guidance for the movement of the mounting cylinder 16. Then, the screws 17 are threaded between the mounting cylinder 16 and the digital compartment 1, thereby locking the relative position of the mounting cylinder 16 and the digital compartment 1. Finally, the mounting holes inside the mounting plate 18 are stably connected to the corresponding threaded holes on the working surface by bolts, thereby achieving stable installation of the digital compartment 1, the panel 5, and other mechanisms.

[0028] The working principle of this novel pipeline digital thermometer is as follows: During operation, the operator first inserts the mounting cylinder 16 into the rear end of the digital compartment 1. The ribs at both ends of the mounting cylinder 16 slide within their corresponding grooves, providing guidance for the movement of the mounting cylinder 16. Then, the operator threaded screws 17 between the mounting cylinder 16 and the digital compartment 1, thereby locking their relative positions. Next, the operator uses bolts to stably connect the mounting holes inside the mounting plate 18 with the corresponding threaded holes on the working surface, thus achieving stable installation of the digital compartment 1, the panel 5, and other mechanisms. After stable installation, the operator moves the thermometer away from the digital compartment. When the fixed rod 36 is moved in the direction of the center of compartment 1, the fixed rod 36 drives the corresponding limiting handle 34 to move away from the center of digital compartment 1 around the central axis of the radially adjacent rotating shaft 33. This causes the torsion spring 35 to exert a torque. When the rubber cylinder 37 separates from the temperature sensing wire 9 to a certain distance, the operator rotates the temperature sensing wire 9 to release it. When the temperature sensing wire 9 is released to the required length, the operator stops moving the fixed rod 36. The elastic force of the torsion spring 35 acts on the corresponding limiting handle 34, and the limiting handle 34 rotates towards the center of digital compartment 1 around the central axis of the radially adjacent rotating shaft 33. This causes the fixed rod 36 to rotate away from the center of digital compartment 1 around the central axis of the radially adjacent rotating shaft 33. The central axis of the rotating shaft 33 moves towards the center of the digital chamber 1. The movement of the fixed rod 36 causes the longitudinally adjacent rubber cylinders 37 to move towards the center of the digital chamber 1. The outer surface of the rubber cylinder 37 re-contacts the temperature sensing wire 9 between the fixed rings 31, thus limiting the release of the unreleased temperature sensing wire 9. Then, the personnel install the probe 11 into the high-pressure pipeline through the terminal block 10. The personnel then control the analog-to-digital converter 7 and the temperature sensor 8 through the controller 6. The probe 11 collects the fluid temperature information inside the high-pressure pipeline and transmits the collected temperature analog information to the signal receiver of the temperature sensor 8 through the temperature sensing wire 9. At the end, the temperature sensor 8 transmits the temperature analog signal to the signal receiving end of the analog-to-digital converter 7. The analog-to-digital converter 7 converts the temperature analog signal into a digital signal and transmits the digital signal to the signal receiving end of the controller 6. Then, the controller 6 enables the display screen 13 to operate and display the temperature in real time. When the temperature value exceeds the standard, the controller 6 enables the speaker 15 to operate and sound an alarm. At the same time, personnel can issue commands to the controller 6 through the keypad 14 to control the working status of the entire pipeline digital thermometer. When an external power interruption occurs, the lithium battery 12 supplies power to the controller 6 to ensure the normal operation of the pipeline digital thermometer.

[0029] It is worth noting that the analog-to-digital converter 7 disclosed in the above embodiments can be an MS5193T, the temperature sensor 8 can be a TMT423, and the controller 6 controls the operation of the analog-to-digital converter 7, the temperature sensor 8, the lithium battery 12, the display screen 13, the keypad 14 and the speaker 15 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
