[0002] As an essential component in building materials, the quality of cement directly affects the building structure and safety. Therefore, cement detection is very important. Through cement detection, problems existing in cement can be discovered in time, so as to take measures to eliminate potential hazards and ensure the quality and safety of buildings. During the process of cement detection, first, a sampler is needed to take samples of cement, and the sampling position needs to be correct to ensure the accuracy of the detection results. In the prior art, most cement detection samplers use stainless steel sampling tubes for detection. By inserting the sampling tube into the cement, the cement enters the inside of the sampling tube to complete the sampling. However, during the sampling process, cement at different depths will enter the inside of the sampling tube, and the sampling position is not accurate enough, affecting the accuracy of the cement detection results.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , this embodiment provides a technical solution: an automatic sampler for cement detection, including a handle 1 and a driving mechanism 8;

[0023] Handle 1: A sampling tube 2 is provided on its left side, providing space for sampling cement. A sampling hole 3 is provided at the left end of the outer arc surface of the sampling tube 2, facilitating the entry of cement into the interior of the sampling tube 2. A retaining ring 4 is provided in the middle of the inner arc surface of the sampling tube 2. A rotating column 5 is rotatably connected inside the retaining ring 4. A spiral blade 6 and a material retaining cylinder 7 are respectively provided at the left end of the outer arc surface of the rotating column 5. The material retaining cylinder 7 is located on the left side of the spiral blade 6. Both the spiral blade 6 and the material retaining cylinder 7 are in contact with the inner arc surface of the sampling tube 2. When the material retaining cylinder 7 coincides with the sampling hole 3, it blocks the entry of cement into the interior of the sampling tube 2. When the spiral blade 6 coincides with the sampling hole 3, through the rotation of the spiral blade 6, a rightward push is applied to the cement entering the sampling tube 2, causing the cement to be stored between the retaining ring 4 and the spiral blade 6. A storage battery 10 is provided inside the handle 1, providing power for the operation of the entire device. A control switch group 9 is provided on the outer arc surface of the handle 1 to control the start and stop of the entire device. The input end of the control switch group 9 is electrically connected to the output end of the storage battery 10. A handle sleeve 11 is provided on the outer arc surface of the handle 1. The handle sleeve 11 is a rubber sleeve, increasing the friction on the surface of the handle 1 and facilitating the grasping by personnel. A scale plate 12 is provided on the outer arc surface of the sampling tube 2 to determine the depth of insertion of the sampling tube 2 into the cement;

[0024] Driving mechanism 8: It is respectively arranged inside the handle 1 and at the right end of the sampling tube 2. The driving mechanism 8 is fixedly connected to the right end of the rotating column 5. The driving mechanism 8 includes a motor 81, a rotating rod 82 and a rotating cylinder 83. The rotating cylinder 83 is arranged at the right end of the rotating column 5. The rotating rod 82 is horizontally slidably connected inside the rotating cylinder 83. The motor 81 is arranged at the left end of the handle 1. The left end of the output shaft of the motor 81 is fixedly connected to the rotating rod 82. The input end of the motor 81 is electrically connected to the output end of the control switch group 9. When the motor 81 is started, the output shaft of the motor 81 drives the rotating rod 82 to rotate. Through the horizontal sliding of the rotating rod 82 and the rotating cylinder 83, the relative rotation of the rotating rod 82 and the rotating cylinder 83 is restricted, driving the rotating cylinder 83, the rotating column 5 and the spiral blade 6 to rotate. The driving mechanism 8 further includes an electromagnetic ring 84. The electromagnetic ring 84 is arranged on the left side surface of the handle 1. The electromagnetic ring 84 is located inside the sampling tube 2. The central axis of the electromagnetic ring 84 is collinear with the central axis of the rotating rod 82. The electromagnetic ring 84 is cooperatively installed with the magnet ring at the right end of the rotating cylinder 83. The input end of the electromagnetic ring 84 is electrically connected to the output end of the control switch group 9. The driving mechanism 8 further includes a tension spring 85. The tension spring 85 is arranged between the right side surface of the rotating cylinder 83 and the left side surface of the handle 1. The tension spring 85 is attached to the inner arc surface of the sampling tube 2. When the electromagnetic ring 84 is energized to generate magnetic force, the magnetic force of the electromagnetic ring 84 is the same as the magnetic force of the magnet at the right end of the rotating cylinder 83. Using the principle of like poles repelling each other, overcoming the elastic force of the tension spring 85, the rotating cylinder 83 is pushed to move leftward, so that the spiral blade 6 coincides with the sampling hole 3. Similarly, when the electromagnetic ring 84 is powered off, under the action of the elastic force of the tension spring 85, the baffle cylinder 7 is reset.

[0025] The working principle of an automatic sampler for cement detection provided by the present utility model is as follows: During the process of cement detection, the sampling tube 2 is inserted into the cement. During the insertion process, under the action of the elastic force of the tension spring 85, a rightward acting force is applied to the rotating cylinder 83, maintaining the state where the baffle cylinder 7 coincides with the sampling hole 3. At this time, blocked by the baffle cylinder 7, cement is prevented from entering the inside of the sampling tube 2. The depth of insertion of the sampling tube 2 into the cement is determined through the scale on the surface of the scale plate 12. Then, the motor 81 is started through the control switch group 9. The output shaft of the motor 81 drives the rotating rod 82 to rotate. Through the horizontal sliding of the rotating rod 82 and the rotating cylinder 83, the relative rotation of the rotating rod 82 and the rotating cylinder 83 is restricted, driving the rotating cylinder 83, the rotating column 5 and the spiral blade 6 to rotate. At the same time, the electromagnetic ring 84 is energized to generate magnetic force. The magnetic force of the electromagnetic ring 84 is the same as the magnetic force of the magnet at the right end of the rotating cylinder 83. Using the principle of like poles repelling each other, overcoming the elastic force of the tension spring 85, the rotating cylinder 83 is pushed to move leftward, so that the spiral blade 6 coincides with the sampling hole 3. At this time, the cement at a specified depth inside the cement will enter the inside of the sampling tube 2 through the sampling hole 3 and move rightward under the thrust generated by the rotation of the spiral blade 6, automatically sampling the cement at the specified depth. After the sampling is completed, the electromagnetic ring 84 is powered off. Under the action of the elastic force of the tension spring 85, the baffle cylinder 7 is reset, and at the same time, the rotation of the rotating rod 82 is stopped. The sampling tube 2 is pulled out of the cement, completing the sampling work for cement detection.

[0026] It should be noted that the motor 81 and the electromagnetic ring 84 disclosed in the above embodiments can be freely configured according to the actual application scenarios. The motor 81 can be a motor of model RF300, and the electromagnetic ring 84 can be an annular electromagnet of model H12030. The control switch group 9 is provided with switch buttons corresponding one by one to the motor 81 and the electromagnetic ring 84 for controlling their switching operations.

[0027] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
