DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 8 As shown, a temperature monitoring device during concrete construction according to the present invention comprises a pre-buried pipe 1 and a temperature measuring column 2;

[0040] A window 3 is provided at the top of the embedded pipe 1; an arc-shaped mounting plate 4 is hinged inside the window 3 through a hinge; a detection port 5 is provided at the bottom of the embedded pipe 1; a heat conducting plate 6 is fixedly connected inside the detection port 5; a coupling block 7 is fixedly connected to the lower side of the heat conducting plate 6;

[0041] The temperature measuring column 2 is located inside the embedded pipe 1; a receiving groove 8 is provided at the bottom of the temperature measuring column 2; a magnetic block 9 is slidably connected inside the receiving groove 8, and the magnetic block 9 and the combining block 7 attract each other; a tension spring 10 is fixedly connected between the upper side of the magnetic block 9 and the receiving groove 8; a temperature sensor 11 is fixedly connected to the lower side of the magnetic block 9; a hollow rope 12 is fixedly connected to one side of the temperature measuring column 2; a temperature measuring wire 13 is arranged inside the hollow rope 12, and the temperature measuring wire 13 extends to the inside of the temperature measuring column 2 and is connected to the temperature sensor 11.

[0042] In order to monitor the temperature inside concrete, the prior art usually embeds a temperature sensor 11 or a temperature measuring probe inside the concrete, and extends the temperature measuring wire 13 to the outside of the concrete to transmit temperature data. However, after the construction is completed, the temperature sensor 11 and the temperature measuring wire 13 are difficult to remove from the concrete, and the equipment cannot be reused, resulting in increased construction costs.

[0043] The present invention fixes a plurality of embedded pipes 1 inside the concrete formwork before construction, then opens the mounting plate 4 at the window 3, places the temperature measuring column 2 inside the embedded pipe 1, and makes the temperature sensor 11 align with the detection port 5, and then closes the mounting plate 4. At this time, the magnetic block 9 and the combining block 7 attract each other, prompting the magnetic block 9 to slide downward inside the receiving groove 8, and making the detection end of the temperature sensor 11 fit the upper side of the heat conducting plate 6, and the tension spring 10 is in a stretched state. After pouring the concrete, the embedded pipe 1 and the temperature measuring column 2 are both located inside the concrete, while the end of the embedded pipe 1 and the end of the hollow rope 12 are located outside the concrete, and the lower side of the heat conducting plate 6 contacts with the concrete, so that the temperature sensor 11 is used to measure the temperature of each position inside the concrete, and the hardening process of the concrete is monitored, so as to adjust the temperature control scheme in time and improve the molding quality of the concrete structure.

[0044] When the maintenance is completed, the temperature measuring column 2 is pulled outward by the hollow rope 12, so that the temperature measuring column 2 slides inside the embedded pipe 1, and then the temperature sensor 11 is separated from the heat conducting plate 6, the magnetic block 9 and the combining block 7 are misaligned with each other, and the tension spring 10 pulls the magnetic block 9 to move upward, thereby collecting the temperature sensor 11 into the storage groove 8 to prevent the end of the temperature sensor 11 from rubbing against the inner wall of the embedded pipe 1 during the pulling process of the temperature measuring column 2, thereby preventing the temperature sensor 11 from being damaged. After the temperature measuring column 2 is successfully pulled out, the temperature measuring column 2, the temperature sensor 11 and the temperature measuring wire 13 are recovered, so that they can be reused, thereby reducing the cost of concrete construction.

[0045] A group of heat conducting fins 14 are evenly distributed on the lower side of the heat conducting plate 6. By providing a plurality of heat conducting fins 14, the contact area between the heat conducting plate 6 and the concrete is increased, and the efficiency of heat conduction to the temperature sensor 11 through the heat conducting fins 14 and the heat conducting plate 6 is improved, thereby improving the detection accuracy of the internal temperature of the concrete.

[0046] As a preferred embodiment of the present invention, a guide plate 15 is fixedly connected to the bottom of the temperature sensor 11, and the temperature sensor 11 passes through the guide plate 15; a pair of guide rollers 16 are rotatably connected to both ends of the guide plate 15. By providing the guide plate 15 and the guide rollers 16, in the process of pulling the temperature measuring column 2, the temperature sensor 11 first slides on the surface of the heat conducting plate 6, and then when it moves to the intersection of the heat conducting plate 6 and the embedded pipe 1, it uses the guide rollers 16 to roll on the intersection step, which plays a guiding and buffering role, and prevents the temperature sensor 11 from directly colliding with the step and causing the problem of reduced service life.

[0047] As a preferred embodiment of the present invention, an elastic member 17 is fixedly connected to the top of the storage groove 8; a movable plate 18 is fixedly connected to the lower side of the elastic member 17; a pair of slide grooves 19 are opened on both sides of the bottom of the storage groove 8; an opening and closing plate 20 is slidably connected inside the slide groove 19; a compression spring 21 is fixedly connected between the opening and closing plate 20 and the slide groove 19, and the compression spring 21 is in a compressed state; a connecting rope 22 is fixedly connected between the end of the opening and closing plate 20 away from the temperature sensor 11 and the upper side of the movable plate 18, and the connecting rope 22 is in a taut state.

[0048] In this embodiment, a guide wheel is preferably provided at the turning point of the connecting rope 22 so that the connecting rope 22 can smoothly transition when turning. When the connecting rope 22 moves, it drives the guide wheel to rotate, which can reduce the resistance and wear of the connecting rope 22.

[0049] When the temperature measuring column 2 is pulled, the magnetic block 9 and the combining block 7 are misaligned with each other, and then the tension spring 10 pulls the magnetic block 9 to move upward. After the magnetic block 9 moves a certain distance, it drives the movable plate 18 to move upward, so that the connecting rope 22 is in a relaxed state, and then the compression spring 21 pushes the opening and closing plate 20 to slide to the outside of the slide groove 19, so that a pair of opening and closing plates 20 are close to each other and the storage groove 8 is closed, and the temperature sensor 11 is further closed inside the storage groove 8 and protected, to prevent foreign objects from entering the storage groove 8 and damaging the temperature sensor 11 during the process of pulling the temperature measuring column 2.

[0050] As a preferred embodiment of the present invention, a water storage chamber 23 is provided inside the temperature measuring column 2; a pressure plate 24 is slidably connected inside the water storage chamber 23; a telescopic rod 25 is fixedly connected between the lower side of the pressure plate 24 and the water storage chamber 23; the telescopic rod 25 is composed of a plurality of hollow tubes slidably connected to each other; the interior of the elastic member 17 is designed to be a hollow structure, and the elastic member 17 and the telescopic rod 25 are connected by a conduit 26; a guide hole 27 is provided on the top of the temperature measuring column 2; a water injection hole 28 is provided on the side of the temperature measuring column 2; the guide hole 27 and the water injection hole 28 are both connected to the water storage chamber 23. When installing the temperature measuring column 2, water (or other liquids that can play a lubricating role) is injected into the water storage chamber 23 through the water injection hole 28. Then, when pulling the temperature measuring column 2, the magnetic block 9 moves upward and uses the movable plate 18 to squeeze the elastic member 17, and squeezes the air inside the elastic member 17 into the telescopic rod 25 through the conduit 26, causing the telescopic rod 25 to extend and push the pressing plate 24 to move upward, and then the pressing plate 24 squeezes the water inside the water storage chamber 23 upward through the guide hole 27. The water flows downward along the gap between the temperature measuring column 2 and the embedded pipe 1, and is evenly distributed on the circumferential surface of the temperature measuring column 2, which plays a lubricating role, reduces the resistance between the temperature measuring column 2 and the embedded pipe 1, reduces the possibility of the temperature measuring column 2 getting stuck, and effectively reduces the wear of the outer surface of the temperature measuring column 2, thereby extending its life of repeated use.

[0051] As a preferred embodiment of the present invention, a water storage tank 29 is opened on the upper side of the temperature measuring column 2; the water storage tank 29 is connected to the water storage chamber 23 through a guide hole 27, and a one-way valve is arranged inside the guide hole 27; a group of coating rollers 30 are rotatably connected inside the water storage tank 29; a water absorption ring 31 is fixedly connected to the surface of the coating roller 30, and the water absorption ring 31 is attached to the inner side of the embedded pipe 1, and the material of the water absorption ring 31 can be foam, sponge, absorbent cloth, etc. When the water inside the water storage chamber 23 is squeezed upward through the guide hole 27, a part of the water flows out upward through the water storage groove 29 and is distributed between the temperature measuring column 2 and the embedded pipe 1, and the other part of the water is temporarily stored in the water storage groove 29. Later, in the process of pulling the temperature measuring column 2, the coating roller 30 and the water absorption ring 31 roll on the inner surface of the embedded pipe 1. When the water absorption ring 31 partially rotates to the bottom, it can absorb water from the water storage groove 29. When the water absorption ring 31 rotates to the top, it is squeezed by the inner wall of the embedded pipe 1 and the coating roller 30, thereby squeezing out the water inside the water absorption ring 31 and coating it on the inner surface of the embedded pipe 1. In the subsequent process of pulling the temperature measuring column 2, the water in the water storage groove 29 can be continuously and evenly applied between the embedded pipe 1 and the temperature measuring column 2 by the water absorption ring 31, instead of squeezing out the water all at once, thereby improving the uniformity, continuity and durability of the lubrication effect, so that the entire pulling process can be lubricated.

[0052] As a preferred embodiment of the present invention, the surface of the water absorption ring 31 is provided with an annular groove 32; a group of elastic paddles 33 are evenly distributed inside the annular groove 32, and the paddles 33 are designed to be impermeable. By providing the annular groove 32 and the paddles 33, during the rotation of the water absorption ring 31, the water at the bottom of the water storage tank 29 can enter the annular groove 32, and the paddles 33 are used to continuously throw the water at the bottom obliquely upward to the inner surface of the embedded pipe 1, thereby improving the efficiency of applying water, and the direction of throwing is exactly the forward path of the temperature measuring column 2, which can play the role of early lubrication and further enhance the lubrication effect on the front end of the temperature measuring column 2.

[0053] A support block 34 is fixedly connected to the bottom of the water storage tank 29 at a position corresponding to the annular groove 32; an elastic hook piece 35 is fixedly connected to the top of the support block 34. When the paddle 33 rotates to the bottom, the paddle 33 and the hook piece 35 squeeze each other, causing the paddle 33 to deform, and then when the paddle 33 passes over the hook piece 35, the paddle 33 swings back obliquely upward under the action of its own elasticity, improving the efficiency and strength of the water swinging, increasing the splashing distance of the water droplets, thereby further increasing the lubrication area, and the paddle 33 can shake when being moved by the hook piece 35, and then the paddle 33 is used to drive the water absorption ring 31 to vibrate, causing dust and other foreign matter inside the water absorption ring 31 to fall downward, preventing the water absorption ring 31 from being blocked, thereby maintaining its water absorption performance and application efficiency ( Figure 8The arc arrow in the figure indicates the rotation direction of the coating roller 30, and the straight arrow indicates the ejection direction of the water droplets).

[0054] like Fig. 9 As shown, the method for using a temperature monitoring device during concrete construction according to the present invention is applicable to the temperature monitoring device during concrete construction, and comprises the following steps:

[0055] S1: pre-fix the embedded pipe 1 inside the concrete formwork, open the mounting plate 4 at the window 3, place the temperature measuring column 2 inside the embedded pipe 1, and align the temperature sensor 11 with the detection port 5, and then close the mounting plate 4;

[0056] S2: The magnetic block 9 and the binding block 7 attract each other, causing the magnetic block 9 to slide downward inside the receiving groove 8, and causing the detection end of the temperature sensor 11 to fit the upper side of the heat conducting plate 6;

[0057] S3: After pouring concrete, the embedded pipe 1 and the temperature measuring column 2 are both located inside the concrete, the lower side of the heat conducting plate 6 is in contact with the concrete, and the temperature inside the concrete is measured by the temperature sensor 11 to monitor the hardening process of the concrete;

[0058] S4: After the maintenance is completed, the temperature measuring column 2 is pulled outward by the hollow rope 12, so that the temperature sensor 11 is separated from the heat conducting plate 6, the magnetic block 9 is misaligned with the combining block 7, and the tension spring 10 pulls the magnetic block 9 upward to store the temperature sensor 11 in the storage slot 8;

[0059] S5: The magnetic block 9 moves upward for a certain distance, driving the movable plate 18 to move upward, and then the compression spring 21 pushes the pair of opening and closing plates 20 to move closer to each other, further sealing the temperature sensor 11 inside the receiving groove 8 and protecting it;

[0060] S6: The movable plate 18 presses the elastic member 17 upward, and squeezes the air inside the elastic member 17 into the telescopic rod 25, so that the telescopic rod 25 extends and pushes the pressing plate 24 to move upward, and squeezes the water inside the water storage chamber 23 upward through the guide hole 27 to play a lubricating role.

[0061] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
