Description

Technical Field

[0001] A portable temperature monitoring instrument for large-volume concrete construction in wind farms is disclosed, which is used for temperature monitoring during large-volume concrete construction in wind farms and belongs to the technical field of portable temperature monitoring instruments. Background Technology

[0002] In wind farm projects, in order to ensure the quality of concrete and control the temperature difference between the inside and outside of the concrete, it is necessary to monitor and control the temperature of the concrete, so a temperature monitoring instrument is required.

[0003] In existing technologies, temperature measurement begins immediately after concrete pouring. In the early stages of pouring, the temperature sensor probe is fixed at three points on the top, middle, and bottom of the wind turbine foundation concrete. The temperature measuring wire is secured to prevent it from falling off, and the equipment is fixed near the temperature measuring points. This enables real-time monitoring of the temperature during concrete pouring and curing, facilitating the implementation of thermal insulation and curing measures to prevent thermal stress and cracks in the concrete.

[0004] Existing temperature monitoring devices have the following technical problems:

[0005] The probes of temperature sensors placed in the upper, middle, and lower parts of the wind turbine foundation concrete are easily affected by the impact or vibration during pouring, which may cause them to shift or tilt. This results in inaccurate measurement positions, meaning that the temperature distribution inside the concrete cannot be accurately reflected, which directly leads to the inapplicability of the curing measures adopted. Utility Model Content

[0006] The purpose of this utility model is to provide a portable temperature monitoring instrument for the construction of large-volume concrete in wind farms. This instrument solves the problem that the probes of temperature sensors placed in the upper, middle and lower parts of the wind turbine foundation concrete are easily affected by the impact or vibration during pouring, resulting in displacement or tilting. This causes inaccurate measurement positions, which means that the temperature distribution inside the concrete cannot be accurately reflected, and directly leads to the inapplicability of the adopted curing measures.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A portable temperature monitoring instrument for large-volume concrete construction in wind farms includes a temperature sensor, a monitoring instrument body connected to the temperature sensor, an installation structure for mounting the temperature sensor at the top, middle and bottom, and a fixing structure set on the installation structure for fixing the installation structure to the reinforcing steel.

[0009] Furthermore, the mounting structure is provided with a T-shaped groove running longitudinally;

[0010] The fixing structure includes a slider that is slidably disposed on a T-shaped groove, two elastic clamps that clamp the reinforcing bar on the slider, a through hole on the elastic clamps, and bolts and nuts that cooperate with the through hole to fix the two elastic clamps to the reinforcing bar.

[0011] Furthermore, at opposite ends of the installation structure, inclined clamps are provided on the two elastic clamps, forming a figure-eight structure.

[0012] Furthermore, the mounting structure includes a square frame with openings on opposite sides, a first mounting structure disposed on the square frame for fixing a lower temperature sensor and supporting a middle temperature sensor, a second mounting structure disposed on the square frame for fixing a middle temperature sensor and supporting an upper temperature sensor, and a third mounting structure disposed on the square frame for fixing an upper temperature sensor.

[0013] The fixing structure is set on the square frame.

[0014] Furthermore, the first mounting structure and the second mounting structure include mounting plates disposed on opposite sides of the inner side of the square frame, a return spring A disposed on the bottom surface of the mounting plate and a movable plate A connected to the return spring A, a threaded hole A disposed on the mounting plate, and a bolt A threaded on the threaded hole A for pushing the movable plate A in the first mounting structure to cooperate with the square frame and for the movable plate A in the second mounting structure to cooperate with the mounting plate in the first mounting structure to clamp the lower and middle temperature sensors.

[0015] Furthermore, the threaded holes A are located at both ends of the mounting plate, and at positions corresponding to the gap formed by the temperature sensor and the square frame; or

[0016] The mounting plate is provided with a groove, and the threaded hole A is located in the groove. After the bolt A is engaged with the threaded hole A, the nut of the bolt A is placed in the groove.

[0017] Furthermore, a threaded hole B is provided on one end of the top of the square frame;

[0018] The third mounting structure includes a return spring B disposed at one end of the top of the square frame, a movable plate B connected to the return spring B, and a bolt B for clamping the upper temperature sensor by engaging with the mounting plate on the second mounting structure via a threaded hole B.

[0019] Furthermore, rubber pads that come into contact with the temperature sensor are provided on the bottom surface of the moving plate A and the moving plate B, the inner side of the square frame located at one bottom end, and the mounting plate.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] I. This utility model fixes the temperature sensor at the top, middle and bottom through the installation structure. The fixing structure can ensure that the temperature sensor probe remains in a fixed position during the concrete pouring process, reducing the offset or tilt caused by impact or vibration, thereby improving the measurement accuracy. In other words, it can more realistically reflect the temperature distribution inside the concrete and take effective curing measures.

[0022] Second, the longitudinally arranged T-shaped groove in this utility model facilitates the vertical movement of the slider within the groove. After the two elastic clamps on the slider are clamped onto the reinforcing bars, the installation structure can slide downwards and contact the bottom of the wind turbine foundation concrete pouring through the gravity of the installation structure and the temperature sensor. At the same time, the two elastic clamps are fixed with bolts and nuts to firmly clamp the reinforcing bars. After fixing, during the concrete pouring process, the offset or tilt of the installation structure caused by the impact or vibration of the concrete can be reduced, thereby ensuring the accurate measurement position of the temperature sensor.

[0023] Third, this utility model has inclined clamping pieces on the two elastic clamps in a figure-eight shape, which makes it easy to slide the steel bar through the large end of the figure-eight structure, so as to avoid the difficulty of clamping the elastic clamps on the steel bar.

[0024] IV. The installation structure in this utility model, by setting a first installation structure, a second installation structure and a third installation structure on a square frame, facilitates the simultaneous fixing and support of multiple temperature sensors on the square frame, thereby enabling temperature monitoring at different depths in the upper, middle and lower parts of the concrete structure.

[0025] V. In this utility model, the first mounting structure and the second mounting structure respectively use the reset action of the reset spring A to push the moving plate A to initially fix the temperature sensors in the lower and middle parts. Then, the moving plate A is pushed by the threaded bolt A on the threaded hole A, so that the moving plate A in the first mounting structure cooperates with the square frame and the moving plate A in the second mounting structure cooperates with the mounting plate in the first mounting structure to clamp the temperature sensors in the lower and middle parts, so as to quickly and easily fix and clamp the temperature sensors in the lower and middle parts.

[0026] VI. The purpose of this utility model in defining the setting position of the threaded hole A is to prevent the bolt A from affecting the installation of the temperature sensor thereon.

[0027] VII. In this utility model, the third mounting structure uses the reset action of the reset spring B to push the moving plate B to initially fix the temperature sensors in the lower and middle parts. Then, the moving plate B is pushed by the threaded bolt B on the threaded hole B, so that the moving plate B cooperates with the mounting plate on the second mounting structure to clamp the upper temperature sensor, so that the upper temperature sensor can be quickly and easily fixed and clamped.

[0028] 8. In this utility model, rubber pads are provided on the bottom surface of moving plate A and moving plate B, the inner side of the square frame at one end of the bottom, and the mounting plate to increase the friction with the temperature sensor, prevent the temperature sensor from sliding in position, and ensure the accuracy of measurement.

[0047] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0048] Example 1

[0049] This addresses the problem that existing temperature sensors placed in the upper, middle, and lower sections of the wind turbine foundation concrete are susceptible to displacement or tilting due to impacts or vibrations during pouring. This results in inaccurate measurement positions, failing to accurately reflect the internal temperature distribution of the concrete and directly rendering curing measures unsuitable. For example... Figure 1-10 As shown, a portable temperature monitoring instrument for large-volume concrete construction in wind farms is provided, including a temperature sensor 1, a monitoring instrument body connected to the temperature sensor (which can be electrically connected or connected in other ways to transmit the temperature sensed by the temperature sensor to the monitoring instrument body for construction personnel to observe and facilitate maintenance), including an installation structure 2 for mounting the temperature sensor 1 at the top, middle and bottom, and a fixing structure 3 set on the installation structure 2 for fixing the installation structure 2 to the reinforcing steel.

[0050] In practice, three temperature sensors are fixed at the top, middle, and bottom of the mounting structure, respectively, allowing their probes to detect the temperature at each location. After fixing, the mounting structure is used in conjunction with the reinforcing steel bars tied to the concrete of the wind turbine foundation to be poured, thus securing the temperature sensors on the mounting structure 2. In this embodiment, after fixing the temperature sensors at the top, middle, and bottom using the mounting structure, the fixing structure ensures that the temperature sensor probes remain in a fixed position during concrete pouring, reducing displacement or tilting caused by impact or vibration, thereby improving measurement accuracy. This allows for a more accurate reflection of the internal temperature distribution of the concrete, enabling the implementation of effective curing measures.

[0051] Example 2

[0052] Based on embodiment 1, the mounting structure 2 is provided with a T-shaped groove 4 longitudinally; the two ends of the T-shaped groove 4 can be open or closed. The fixing structure 3 includes a slider 5 slidably disposed on the T-shaped groove 4, two elastic clamps 6 disposed on the slider 5 to clamp the reinforcing bar, a through hole 7 disposed on the elastic clamp 6, and bolts 8 and nuts 9 that cooperate with the through hole 7 to fix the two elastic clamps 6 to the reinforcing bar.

[0053] In practice, the mounting structure 2, equipped with a temperature sensor, is positioned with one end below the reinforcing bars through the gaps between the tied reinforcing bars. The elastic clamps 6 in the T-shaped groove 4 are then clamped onto a reinforcing bar and secured with bolts 8 and nuts 9. After fixing, before the lower end of the mounting structure 2 is in contact with the bottom of the wind turbine foundation concrete to be poured, the sliding contact between the slider 5 and the T-shaped groove 4 brings the lower end of the mounting structure into contact with the bottom of the wind turbine foundation concrete. In this embodiment, the longitudinally arranged T-shaped groove facilitates the slider's up-and-down movement within the groove. After the two elastic clamps on the slider are clamped onto the reinforcing bars, the weight of the mounting structure and the temperature sensor allows the mounting structure to slide downwards and contact the bottom of the wind turbine foundation concrete. Simultaneously, the bolts and nuts securely hold the reinforcing bars with the two elastic clamps. After fixing, during concrete pouring, the offset or tilting of the mounting structure caused by the impact or vibration of the concrete is reduced, thus ensuring the accurate measurement position of the temperature sensor. Of course, in practice, other methods of fixing and installation can be used depending on the actual situation.

[0054] Example 3

[0055] Based on Embodiment 2, inclined clamping pieces 10 are provided on the two elastic clamps 6 at opposite ends of the installation structure 2, forming a figure-eight structure. This invention provides inclined clamping pieces on the two elastic clamps in a figure-eight shape, facilitating the sliding of the reinforcing bar through the larger end of the figure-eight structure, thus avoiding difficulties in clamping the elastic clamps onto the reinforcing bar.

[0056] Example 4

[0057] Based on Embodiment 3, the mounting structure 2 includes a square frame 11 with openings on opposite sides, a first mounting structure 12 disposed on the square frame 11 for fixing the lower temperature sensor 1 and supporting the middle temperature sensor 1, a second mounting structure 13 disposed on the square frame 11 for fixing the middle temperature sensor 1 and supporting the upper temperature sensor 1, and a third mounting structure 14 disposed on the square frame 11 for fixing the upper temperature sensor; the fixing structure 3 is disposed on the square frame 11. In this embodiment, the mounting structure, by providing the first, second, and third mounting structures on the square frame, facilitates the simultaneous fixing and support of multiple temperature sensors on the square frame, enabling temperature monitoring at different depths (top, middle, and bottom) of the concrete structure.

[0058] Example 5

[0059] Based on embodiment 4, the first mounting structure 12 and the second mounting structure 13 include mounting plates 15 disposed on opposite sides of the inner side of the square frame 11, a return spring A16 disposed on the bottom surface of the mounting plate 15 and a movable plate A17 connected to the return spring A16, a threaded hole A18 disposed on the mounting plate 15, and bolts A19 threaded on the threaded hole A18 for pushing the movable plate A17 in the first mounting structure 12 to cooperate with the square frame 11 and for the movable plate A17 in the second mounting structure 13 to cooperate with the mounting plate 15 in the first mounting structure 12 to clamp the lower and middle temperature sensors 1.

[0060] In practice, the first and second mounting structures initially fix the lower and middle temperature sensors by pushing the moving plate A through the reset action of the return spring A. Then, the moving plate A is pushed by the threaded bolt A on the threaded hole A, so that the moving plate A in the first mounting structure mates with the square frame, and the moving plate A in the second mounting structure mates with the mounting plate in the first mounting structure to clamp the lower and middle temperature sensors. This allows for quick and easy fixing and clamping of the lower and middle temperature sensors. Generally, it is best to install the lower temperature sensor first, followed by the middle temperature sensor. In practice, this structure also facilitates fixing temperature sensors of different sizes, and the length of bolt A19 and its nut can be selected according to actual needs.

[0061] Example 6

[0062] Based on embodiment 5, the threaded hole A18 is provided at both ends of the mounting plate 15, and is located at the position corresponding to the gap formed by the temperature sensor 1 and the square frame 11; or the mounting plate 15 is provided with a groove 20, the threaded hole A18 is provided in the groove 20, and after the bolt A19 is engaged with the threaded hole A18, the nut of the bolt A19 is placed in the groove 20. The purpose of limiting the setting position of the threaded hole A is to prevent the bolt A from affecting the installation of the temperature sensor on it.

[0063] Example 7

[0064] Based on embodiment 6, a threaded hole B23 is provided on one end of the top of the square frame 11; the third mounting structure 14 includes a return spring B21 provided on one end of the top of the square frame 11, a moving plate B22 connected to the return spring B21, and a bolt B24 for clamping the upper temperature sensor 1 in cooperation with the mounting plate 15 on the second mounting structure 13, which is threaded on the threaded hole B23.

[0065] In practice, the third mounting structure uses the reset action of the return spring B to push the moving plate B to initially fix the temperature sensors in the lower and middle parts. Then, the moving plate B is pushed by the threaded bolt B on the threaded hole B, so that the moving plate B cooperates with the mounting plate on the second mounting structure to clamp the upper temperature sensor. This allows for quick and easy fixing and clamping of the upper temperature sensor. In practice, this structure is also suitable for fixing temperature sensors of different sizes. The length of the bolt B24 and its nut can also be selected according to actual needs.

[0066] Example 8

[0067] Based on embodiment 7, rubber pads 25 that contact the temperature sensor 1 are provided on the bottom surface of the moving plate A17 and the moving plate B22, the inner side of the square frame 11 located at one bottom end, and the mounting plate 15. The purpose is to increase the friction with the temperature sensor, prevent the temperature sensor from sliding in position, and ensure the accuracy of the measurement.
