Description

Technical Field

[0001] The utility model relates to the technical field of building concrete temperature detection, in particular to a concrete temperature detector. Background Art

[0002] The surface temperature of concrete continues to decrease due to heat exchange with the external environment, resulting in a large temperature gradient between the inner and outer layers of concrete, thereby generating large temperature stress, leading to cracks, destroying the integrity of the building, and affecting the life and safety of the building.

[0003] Temperature detection of concrete buildings can be divided into pre-embedded and external detection methods. The current mainstream observation method is the pre-embedded method, which is to bury a dedicated temperature sensor inside the concrete building to measure the temperature state of the building. The external detection method is to use tape to fix the temperature sensor on the steel bar. Both of the above detection methods have problems, as follows:

[0004] The temperature sensor is embedded in the concrete building before pouring. During the concrete pouring process, the cable of the temperature sensor is completely exposed. The sand and gravel inside the concrete can easily scratch the sensor cable, causing damage to the sensor, and the sensor cannot be well protected.

[0005] The external detection method reserves temperature measuring holes during the drying and forming process of the concrete structure. After the concrete is formed, steel bars are used to introduce the temperature sensor into the temperature measuring hole. However, the temperature measuring hole is small in width. When the steel bars introduce the temperature sensor into the hole, the temperature measuring element and cable of the temperature sensor are easily in contact with the side wall of the temperature measuring hole, resulting in wear. Therefore, the service life of the temperature sensor is very short and its practicality is low. Utility Model Content

[0034] The present invention will now be discussed with reference to exemplary embodiments. It should be understood that the embodiments discussed are only intended to enable those skilled in the art to better understand and implement the present invention, rather than to imply any limitation on the scope of the present invention.

[0035] As used herein, the term “including” and variations thereof are to be interpreted as open-ended terms meaning “including, but not limited to.” The term “based on” is to be interpreted as “based, at least in part, on.” The terms “one embodiment” and “an embodiment” are to be interpreted as “at least one embodiment.”

[0036] The following is combined with Figure 1-10 The technical solution of the utility model is described in detail.

[0037] like Figure 1-7 and Fig. 9 As shown, the concrete temperature detector comprises:

[0038] The instrument host 1 is externally connected with a plurality of detection elements 4, the detection elements 4 include cables 7 and probes 8, and the concrete temperature is sensed by the probes 8;

[0039] like Figure 4 and Figure 7As shown, there can be 2 to 8 detection elements 4, and all detection elements 4 are connected to the instrument host 1 via cables 7. The temperature measurement data of the detection elements 4 can be collected through the instrument host 1, and in order to facilitate the subsequent distinction of temperature measurement, each detection element 4 can be named in the instrument host 1, such as detection element 4a, detection element 4b, detection element 4c, etc.

[0040] Before testing the concrete temperature, the detection element 4 and the probe mechanism are installed. The probe mechanism includes a guide tube 3 and a protective cover 5. The outer wall of the guide tube 3 is provided with a plurality of wire grooves 301. The wire grooves 301 are arranged around the outer surface of the guide tube 3. The cables are adjusted into the wire grooves 301. Figure 5 As shown, the wire groove 301 is arc-shaped or semicircular, which just fits the shape of the outer surface of the cable 7, and the cable 7 is positioned through the wire groove 301;

[0041] Further, such as Figure 6 As shown, a buckle 9 is provided on the inner wall of the wire groove 301, and a slot (not shown in the figure) adapted to the buckle 9 is provided on the side of the probe 8 facing the wire groove 301. When pulling the cable 7, the probe 8 is adjusted to correspond to the slot in the wire groove 301, and the probe 8 is pressed so that the slot of the probe 8 is engaged with the buckle 9, and the probe 8 is positioned;

[0042] Furthermore, a wire collection piece 2 is provided between the probe mechanism and the instrument main body 1, and the detection element 4 can be adjusted to pass through the wire collection piece 2 before the detection element 4 and the wire groove 301 are installed, or the end of the cable 7 close to the instrument main body 1 can be extended from the end of the wire groove 301 after the detection element 4 and the wire groove 301 are installed, and then the detection element 4 is adjusted to pass through the wire collection piece 2 and then plugged into the instrument main body 1. The wire collection piece 2 collects the cables to avoid multiple cables 7 from being entangled with each other and affecting the temperature measurement work and the later storage, such as Figure 4 As shown, a connector 10 is provided at the end of the detection element 4 close to the instrument host 1, and the connector 10 can be connected to the instrument host 1. After the above, the detection element 4 and the probe mechanism are preliminarily installed.

[0043] Further, such as Figure 1-Figure 3 , Figure 7-10 As shown, the protective cover 5 is installed outside the guide tube 3. Specifically, the inner diameter of the protective cover 5 is 0.3mm-0.8mm larger than the outer diameter of the guide tube 3. The guide tube 3 is adjusted to be inserted into the protective cover 5. The protective cover 5 is sleeved outside the guide tube 3. The surface of the protective cover 5 is provided with an avoidance groove 11 corresponding to the position of the probe 8. Each avoidance groove 11 is adjusted to correspond to the probe 8. The protective cover 5 will cover the cable 7. The cable 7 is blocked by the protective cover 5, and then the protective cover 5 is tightened. A plurality of groups of connecting pieces 6 are provided on the surface of the protective cover 5 and outside the gap 12, as shown in FIG. Figure 8As shown, each set of connecting plates 6 is composed of two metal plates, and screw holes are opened on the surfaces of the metal plates. The metal plates are locked with bolts, and the gap is reduced. The protective cover 5 is a deformable structure. At the same time, the inner diameter of the protective cover 5 becomes smaller, and the inner wall of the protective cover 5 will be tightly attached to the outer wall of the guide tube 3 to complete the socket fixation of the two. As the inner diameter of the protective cover 5 is reduced, the probe will protrude from the avoidance groove to complete the installation.

[0044] Because the length of the wire groove 301 increases in a clockwise or counterclockwise order, and when multiple detection elements 4 are installed in the wire groove 301, the positions of the probes 8 are different, and they will approach the rear in a clockwise or counterclockwise order. The distance (in the length direction) between each two adjacent probes 8 is 10%-50% of the total length of the probe mechanism, which can realize multi-point segmented temperature measurement and collect temperature data at multiple different positions in the concrete to cooperate with the concrete temperature measurement work.

[0045] Furthermore, the length of the probe mechanism is ≥10 cm. The length of the probe mechanism can be designed according to the use requirements. For example, if the temperature of a large concrete structure is to be measured, the length of the probe mechanism can be made to be more than 2 m.

[0046] Based on the above scheme of the utility model, the specific working principle is as follows:

[0047] When the embedded temperature measurement is adopted, the concrete temperature detector of the utility model is assembled, and then the probe mechanism is placed inside the concrete building, and the position of the line collection part 2 should be located outside the building, and then the concrete is poured. Because the cable in the detection element 4 is shielded, the concrete will not directly contact the cable, and it is not easy to wear it, which can protect the detection element 4;

[0048] When the external detection method is adopted, the concrete temperature detector of the utility model is directly assembled, and then the probe mechanism is inserted into the temperature measuring hole of the concrete building. When the probe mechanism enters the temperature measuring hole, the cable in the detection element 4 is blocked, so the cable will not contact the inner wall of the temperature measuring hole and is not easily worn. It can also protect the detection element 4. After use, the protective cover 5 can be removed, the detection element 4 can be stored, the detection element 4 can be maintained, and the service life can be extended.

[0049] According to the above scheme of the utility model, the utility model collects the cables through the cable collection piece, the protective cover covers the cables, and the probe protrudes from the avoidance groove. When pouring concrete, because the cables in the detection element are blocked, the concrete will not directly contact the cables, and it is not easy to wear them, which can protect the detection element.

[0050] When the probe mechanism enters the temperature measuring hole, the cable in the detection element is blocked, so the cable will not touch the inner wall of the temperature measuring hole and is not easily worn. After use, the protective cover can be removed and the detection element can be stored to maintain the detection element and extend its service life.

[0051] The probes will approach each other in a clockwise or counterclockwise order. The distance between each two adjacent probes is 10%-50% of the total length of the probe mechanism. It can realize multi-point segmented temperature measurement, collect temperature data at multiple different positions in the concrete, and cooperate with the concrete temperature measurement work.

[0052] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
