Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature measuring device technology, specifically to a temperature measuring device that can simultaneously measure the temperature of multiple points at different depths in a mixture. Background Technology
[0002] Currently, asphalt mixture temperature measurement mainly relies on handheld infrared thermometers, insertion thermometers, or fixed temperature measurement systems. While handheld infrared thermometers are easy to operate, they can only measure surface temperature, are greatly affected by environmental factors, and require manual intervention, making real-time monitoring difficult. Insertion thermometers, although capable of measuring the internal temperature of the mixture, have a limited number of measurement points, failing to reflect the overall temperature distribution, and require manual insertion, making operation cumbersome. Fixed temperature measurement systems are typically installed at the mixing plant or paving equipment. While they allow for continuous monitoring, their fixed measurement locations make them difficult to adapt to different construction scenarios, and their limited installation location restricts the measurement range, making it difficult to comprehensively grasp the temperature changes of the mixture. Asphalt mixtures exhibit a significant temperature gradient throughout the construction process. For example, during transportation, there may be a large temperature difference between the inside and surface of the truck bed; the outer layer cools down faster due to environmental influences, while the internal temperature remains relatively stable.
[0003] Therefore, there is an urgent need for a temperature measuring device that can simultaneously measure the temperature at multiple points and different depths in a mixture. Utility Model Content
[0004] The purpose of this invention is to provide a temperature measuring device that can simultaneously measure the temperature of a mixture at multiple points and different depths, in order to overcome the shortcomings of existing technologies, such as fixed measurement positions, difficulty in adapting to different construction scenarios, limited temperature measurement range due to installation location restrictions, and difficulty in fully grasping the temperature changes of the mixture.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A temperature measuring device capable of simultaneously measuring multiple points at different depths in a mixture includes a temperature recorder. Several telescopic rods are mounted on the side of the temperature recorder from top to bottom. Each telescopic rod includes a primary rod, a secondary rod, and a tertiary rod connected sequentially. A wiring harness is connected to the first end of each primary rod, and both the first end of the primary rod and the wiring harness are fixed inside the temperature recorder. A metal temperature sensor is located at the end of each tertiary rod. A temperature display screen and a G-data acquisition terminal are fixedly mounted on the temperature recorder. A fixing component for securing the temperature measuring device to the measurement point is located on the side of the temperature recorder away from the telescopic rods.
[0007] Furthermore, the fixing assembly includes a first fixing beam, a second fixing beam, a third fixing beam, and a fourth fixing beam respectively disposed on the side of the temperature recorder.
[0008] Furthermore, the first-stage rod and the second-stage rod are movably connected by a first spiral buckle, and the second-stage rod and the third-stage rod are movably connected by a second spiral buckle.

[0010] Furthermore, the telescopic rod is provided with a heat insulation layer.
[0011] Furthermore, a wire harness is provided at the end of the first-stage rod and the wire harness is connected to a temperature recorder, and a wire is provided on the third-stage rod and the wire is connected to a temperature recorder.
[0012] Furthermore, anti-slip rubber pads are provided on the first fixed beam, the second fixed beam, the third fixed beam, and the fourth fixed beam.
[0013] Furthermore, the ends of the first, second, third, and fourth fixed beams are all equipped with adjustable fastening bolts to accommodate mounting carriers of different sizes.
[0014] Furthermore, the metal temperature sensor is a K-type thermocouple or an NTC thermistor.
[0015] Furthermore, the metal temperature sensor is welded to the end point of the second end of the three-stage rod.
[0016] Compared with the prior art, the present invention has the following beneficial technical effects:
[0017] This invention provides a temperature measuring device that can simultaneously measure the temperature of a mixture at multiple points and different depths. By uniformly arranging several telescopic rods on the side of the temperature recorder, the metal temperature measuring head at the end of each telescopic rod can simultaneously measure the temperature of the mixture at different points and different depths, thus comprehensively obtaining the temperature distribution of the mixture.

[0019] Specifically, the fixing components, by setting anti-slip rubber pads and adjustable fastening bolts, can ensure the stability of the device when fixed, and can be adapted to installation carriers of different sizes, making them suitable for a variety of engineering scenarios.

The overall structural design is reasonable, the components are tightly connected, and the operation steps are simple and easy to understand, reducing the difficulty and labor intensity of operators and improving work efficiency.

[0031] See Figures 1 to 3 This utility model provides a temperature measuring device capable of simultaneously measuring multiple points at different depths in a mixture, including a temperature recorder 1. Several telescopic rods 3 are evenly installed from top to bottom on the side of the temperature recorder 1. Each telescopic rod 3 includes a primary rod 12, a secondary rod 11, and a tertiary rod 10 connected sequentially. A wire harness 13 is fixedly connected to the end of the primary rod 12 that passes through the side of the temperature recorder 1 and is away from the secondary rod 11. The first end of the tertiary rod 10 is connected to the secondary rod 11, and a metal temperature sensor 9 is installed on the second end for sensing temperature. A temperature display screen 8 and a 4G data acquisition terminal 7 are fixedly installed on the first side of the temperature recorder 1 away from the telescopic rods 3, and a fixing component is installed on the second side of the temperature recorder 1 near the telescopic rods 3. The wire harness 13 is located at the end of the primary rod 12 and connected to the temperature recorder 1. A wire 17 is located on the tertiary rod 10 and connected to the temperature recorder 1. In this embodiment, four telescopic rods 3 are used, and the specific temperature is obtained by the temperature recorder 1 through the wire 17 on the third-level rod 10 and the wire harness 13 at the end of the first-level rod 12. The four telescopic rods 3 evenly installed on the side of the temperature recorder 1 can flexibly adjust their length according to the actual measurement needs, so as to achieve accurate measurement of the temperature of the mixture at different depths.
[0032] In some preferred embodiments of this invention, the first-stage rod 12 and the second-stage rod 11 are movably connected by a first spiral buckle 15, and the second-stage rod 11 and the third-stage rod 10 are movably connected by a second spiral buckle 16, allowing the length of the telescopic rod 3 to be flexibly adjusted according to actual measurement needs. For example, when measuring the temperature of asphalt mixture during road construction, the telescopic rod can be extended to the required depth by rotating the buckle, accurately obtaining temperature data at different levels.
[0033] In some preferred embodiments of this utility model, the fixing components include a first fixing beam 2, a second fixing beam 4, a third fixing beam 5, and a fourth fixing beam 6 respectively disposed on the side of the temperature recorder 1. Each fixing beam is provided with an adjustable fastening bolt at the connection point between it and the side of the temperature recorder 1. The temperature measuring device can be flexibly adjusted according to the difference in the size of the installation carrier, and can achieve stable installation whether it is a large construction equipment or a small testing platform.
[0034] In some preferred embodiments of this utility model, the second end of the three-stage rod 10 is directly welded to the metal temperature measuring head 9, and the metal temperature measuring head 9 is made of K-type thermocouple or NTC thermistor material. This direct welding method not only ensures the firmness of the connection between the metal temperature measuring head 9 and the three-stage rod 10, but also ensures the efficiency and stability of the temperature conduction path, so that the metal temperature measuring head 9 can quickly sense the temperature change of the mixture and provide a guarantee for accurate measurement.
[0035] In some preferred embodiments of this utility model, the length of the first-stage rod 12 is 450mm, the length of the second-stage rod 11 is 500mm, and the length of the third-stage rod 10 is 600mm.
[0036] In some preferred embodiments of this utility model, a heat insulation layer 14 is provided on the telescopic rod 3, which can effectively block the high temperature of the mixture from being transmitted to the temperature recorder 1, and prevent the high temperature from damaging the internal electronic components of the recorder.
[0037] When using the temperature measuring device of this utility model, firstly, according to the size of the mounting carrier, the temperature measuring device is fixed in a suitable position on the mounting carrier by adjusting the fastening bolts at the ends of the first fixed beam 2, the second fixed beam 4, the third fixed beam 5, and the fourth fixed beam 6. Then, according to the required depth of the mixture to be measured, the length of the telescopic rod 3 is adjusted by rotating the first spiral buckle 15 and the second spiral buckle 16. This device has four telescopic rods 3 in different positions, allowing the metal temperature measuring head 9 to be inserted into the mixture to the corresponding depth. Therefore, different temperature measuring points and depths within the measuring range of this utility model can be freely selected to achieve comprehensive temperature measurement at different points and depths. After the measurement is completed, the first spiral buckle 15 and the second spiral buckle 16 are loosened, and the telescopic rod 3 is retracted for easy storage and future use of the device.
[0038] During the production and construction phases, the four fixed beams provide support and stability, allowing the device to smoothly monitor the temperature on the asphalt mixture surface layer in real time, while other operations remain unchanged.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
