Description

Technical Field

[0001] This utility model relates to the field of concrete temperature detection technology, and more specifically, to a pre-embedded device for temperature detection of large-volume concrete foundations. Background Technology

[0002] After large-volume concrete is poured, the hydration of cement generates a large amount of heat, causing the internal temperature of the concrete to rise while the surface temperature remains relatively low, creating a temperature gradient. This temperature difference may cause the concrete to expand and contract. When the stress exceeds the tensile strength of the concrete, cracks will occur. By embedding a temperature detection device, the internal temperature changes of the concrete can be monitored in real time, so that appropriate temperature control measures can be taken to prevent cracks from forming and ensure the quality and durability of large-volume concrete structures.

[0003] A search revealed that Chinese patent CN219908942U discloses a temperature control device for large-volume concrete. The device uses a temperature detection component to detect the temperature inside the concrete structure. An external water supply pipe is connected to a cooling component, allowing water to pass through the cooling pipe. This removes heat from the concrete, and the cooling component cools the water. The cooling power is automatically adjusted based on the temperature detected by the temperature detection component, thereby achieving efficient temperature control and reduction of the concrete.

[0004] When the above-mentioned temperature detection component is in use, a temperature sensor is fixedly connected to the lower end of the connecting rod. However, it is inconvenient to adjust the height of the temperature sensor. The thickness of large-volume concrete foundations varies greatly, and a temperature sensor with a fixed height cannot cover the key temperature measurement layers inside the concrete (such as the surface layer, the middle layer, and the bottom layer), resulting in incomplete temperature detection. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a pre-embedded device for temperature detection of large-volume concrete foundations, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded device for temperature detection of large-volume concrete foundations, comprising an embedded cylinder, a protective frame, and a temperature sensor body. The protective frame is located inside the embedded cylinder, and the temperature sensor body is located inside the protective frame. A lifting ring is fixedly connected to the top of the protective frame, and a connecting rope is wound around the lifting ring. An installation plate is movably installed on the top of the embedded cylinder. Two upright plates are fixedly connected to the top of the installation plate. A self-locking motor is fixedly installed on one side of one of the upright plates. A rotating rod is fixedly connected to the output shaft end of the self-locking motor, and both ends of the rotating rod are movably connected to the two upright plates through bearings. The other end of the connecting rope is wound around the outside of the rotating rod. A connector is threadedly connected to the bottom of the embedded cylinder.

[0007] Furthermore, side plates are fixedly connected to both sides of the mounting plate.

[0008] As can be seen, in the above technical solution, the side plate is installed on the external bracket by bolts, so that the mounting plate is located on the top of the pre-embedded cylinder.

[0009] Furthermore, the temperature sensor body is provided with an adjustment assembly, which includes a stepper motor, a first lead screw, two sliders, a slide bar, a cross plate, two L-shaped plates, two second lead screws, and two pressing plates.

[0010] Furthermore, the stepper motor is fixedly installed inside the protective frame, and the output shaft end of the stepper motor is fixedly connected to the first lead screw. The outer side of the first lead screw is threadedly connected to one of the sliders, and the opposing sides of the two sliders are fixedly connected to the horizontal plate.

[0011] Furthermore, the top end of the slide bar is fixedly connected to the protective frame, and the bottom end of the slide bar penetrates through another horizontal plate.

[0012] It can be seen that the above technical solution restricts the rotation of the horizontal plate.

[0013] Furthermore, the two L-shaped plates are fixedly connected to the horizontal plate on opposite sides, and the two L-shaped plates are respectively threaded to the two second lead screws. The opposite ends of the two second lead screws are respectively fixedly connected to the two extrusion plates, and the opposite sides of the two extrusion plates are in contact with the temperature sensor body.

[0014] It can be seen that the above technical solution facilitates the installation and disassembly of the temperature sensor body.

[0015] Furthermore, each of the two second lead screws has a handle fixedly connected to one of its opposite ends.

[0016] It can be seen that the above technical solution is designed to facilitate the driving of the second lead screw.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model embeds a pre-embedded cylinder in a large volume of concrete. The self-locking motor drives the rotating rod to rotate, thereby moving the connecting rope away from the rotating rod. At this time, the protective frame begins to move downward, thereby driving the temperature sensor body to move downward. The temperature sensor body detects the temperature inside the pre-embedded cylinder. The operation is simple and convenient for detecting concrete at different locations, and it has a wide range of applications.

[0019] 2. This utility model protects the temperature sensor body with a protective frame. The stepper motor drives the temperature sensor body to move downwards and out of the protective frame. Turning the handle drives the second lead screw and the extrusion plate to move horizontally and move the extrusion plate away from the temperature sensor body, allowing the temperature sensor body to be disassembled and replaced. The structure is simple and easy to use. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1-5 The large-volume concrete foundation temperature detection embedded device of this embodiment includes an embedded cylinder 1, a protective frame 2, and a temperature sensor body 10. The protective frame 2 is located inside the embedded cylinder 1, and the temperature sensor body 10 is located inside the protective frame 2. A lifting ring 11 is fixedly connected to the top of the protective frame 2, and a connecting rope 3 is wound around the lifting ring 11. An installation plate 4 is movably installed on the top of the embedded cylinder 1. Two upright plates 12 are fixedly connected to the top of the installation plate 4. A self-locking motor 7 is fixedly installed on one side of one of the upright plates 12. A rotating rod 6 is fixedly connected to the end of the output shaft of the self-locking motor 7, and both ends of the rotating rod 6 are movably connected to the two upright plates 12 through bearings. The other end of the connecting rope 3 is wound around the outside of the rotating rod 6. A connector 8 is threadedly connected to the bottom of the embedded cylinder 1.

[0029] Furthermore, side plates 5 are fixedly connected to both sides of the mounting plate 4.

[0030] Furthermore, the temperature sensor body 10 is provided with an adjustment component 9, which includes a stepper motor 901, a first lead screw 902, two sliders 903, a slide rod 904, a horizontal plate 905, two L-shaped plates 906, two second lead screws 907, and two pressing plates 908. The stepper motor 901 is fixedly installed inside the protective frame 2, and the output shaft end of the stepper motor 901 is fixedly connected to the first lead screw 902. The outer side of the first lead screw 902 is threadedly connected to one of the sliders 903, and the opposing sides of the two sliders 903 are fixedly connected to the horizontal plate 905. The top end of the slide rod 904 is fixedly connected to the protective frame 2, and the bottom end of the slide rod 904 passes through the other horizontal plate 905.

[0031] Furthermore, the two L-shaped plates 906 are fixedly connected to the horizontal plate 905 on their opposite sides, and the two L-shaped plates 906 are respectively threaded to the two second lead screws 907. The opposite ends of the two second lead screws 907 are respectively fixedly connected to the two extrusion plates 908, and the opposite sides of the two extrusion plates 908 are in contact with the temperature sensor body 10. The opposite ends of the two second lead screws 907 are fixedly connected to handles 909.

[0032] The temperature sensor body 10 is protected by a protective frame 2. When the stepper motor 901 is started, it drives the first lead screw 902 to rotate. Since one slider 903 is threadedly connected to the first lead screw 902, and the other slider 903 cooperates with the slide rod 904 to restrict the rotation of the horizontal plate 905, the first lead screw 902 can drive the horizontal plate 905 to move downward, thereby driving the temperature sensor body 10 downward and moving it out of the protective frame 2. Rotating the handle 909 drives the second lead screw 907 and the extrusion plate 908 to move horizontally, moving the extrusion plate 908 away from the temperature sensor body 10. Similarly, adjusting the position of the other extrusion plate 908 releases the fixation between the temperature sensor body 10 and the horizontal plate 905, allowing the temperature sensor body 10 to be disassembled and replaced. The structure is simple and easy to use.

[0033] The usage method of this embodiment is as follows:

[0034] In use, the embedded cylinder 1 is pre-embedded in the large volume of concrete. The connector 8 is rotated and extended into the interior of the embedded cylinder 1. Similarly, another embedded cylinder 1 is placed at the bottom of the connector 8, and the two embedded cylinders 1 are connected through the connector 8. The number of embedded cylinders 1 is increased according to the height of the large volume of concrete. The side plate 5 is installed on the external bracket with bolts, so that the mounting plate 4 is located at the top of the embedded cylinder 1. One end of the connecting rope 3 is tied to the lifting ring 11, and the other end of the connecting rope 3 is wrapped around the rotating rod 6. The self-locking motor 7 is started, and the self-locking motor 7 drives the rotating rod 6 to rotate, so that the connecting rope 3 moves away from the rotating rod 6. At this time, the protective frame 2 begins to move downward, thereby driving the temperature sensor body 10 to move downward. The temperature inside the embedded cylinder 1 is detected by the temperature sensor body 10. Similarly, the self-locking motor 7 reverses, so that the connecting rope 3 is wrapped around the rotating rod 6, thereby driving the protective frame 2 and the temperature sensor body 10 to move upward. The operation is simple, convenient for detecting concrete in different locations, and has a wide range of applications.
