Description

Technical Field

[0001] The invention relates to the technical field of engineering supervision sampling, in particular to a quality inspection sampling device for engineering supervision. Background Art

[0002] Sampling in engineering supervision refers to the process in which engineering supervision personnel collect samples of actual materials, components or engineering sites for testing, analysis and evaluation according to relevant standards and specifications during or after construction to verify the quality, safety and compliance of the project. Sampling is an important task of engineering supervision. Through sampling, engineering materials, structures, construction processes, etc. can be tested and evaluated to ensure that the project meets the design requirements, construction specifications and relevant standards.

[0003] A Chinese utility model with announcement number CN212031005U discloses an engineering supervision sampling system, which includes a cement detection module, a sand and gravel detection module, a concrete detection module and a detection terminal electrically connected to the cement detection module, the sand and gravel detection module and the concrete detection module. The cement detection module includes a cement sampler and a cement quality detector. The cement sampler includes a first cylinder and a second cylinder sleeved in the first cylinder. The first cylinder is provided with a dust prevention component for preventing cement from splashing, and the second cylinder is provided with a collection component for collecting cement. The above application has the advantage of preventing cement dust from flying around during use.

[0004] Although the above-mentioned sampling device can achieve a good sampling effect during the sampling period, the structure of the collection component is relatively simple during the engineering supervision sampling process. During its use, it can only be sampled once each time. After one sampling is completed, it is necessary to manually remove cement from the sampling needle of the collection component before a second sampling can be performed. It can be seen that the overall sampling operation is relatively cumbersome and inconvenient, and during the sampling process, it is necessary to set up a container to store the cement sample. The overall use is relatively complicated, and a special tool box or external container is required to store the cement sample. In addition, during the use of the device, the drill bit is manually adjusted for sampling, and the overall adjustment of the sampling is relatively laborious. It can be seen that the overall use is relatively inconvenient. Summary of the invention

[0019] Secondly, in the present invention, suction is generated by the operation of the suction fan to absorb cement fly ash samples, so that the device can quickly collect concrete cement fly ash. During use, the input end of the connecting pipe can be switched according to the collection needs. During the sample collection period, the solenoid valve at the corresponding position can be opened to introduce dust debris into the interior of the collection mechanism.

[0020] Thirdly, in the present invention, during the operation of the suction fan, the one-way plate is pushed open by air pressure to force the air ash containing cement ash into the filter frame, and the filter screen filters the cement sample, so that the cement ash can be collected inside the filter frame. After the collection of the cement fly ash sample is completed, the solenoid valve at the corresponding position is closed. At this time, the connecting pipe loses its suction force, and the magnetic plate adsorbs the one-way plate to close the bottom of the filter frame, which can prevent dust from falling from the bottom, making the device easy to collect fly ash. The design of the collection mechanism integrated in the shell can automatically collect cement samples during use, so that the device only needs to be carried during use, and there is no need to carry an external container, and the overall operation is more convenient.

[0021] Fourthly, in the present invention, the design of automatic storage of samples can reduce manual operations, improve sampling efficiency, ensure the accuracy and representativeness of samples, avoid human errors or sampling deviations, facilitate the recording and management of samples, and facilitate subsequent detection, analysis and tracking. It can reduce the interference of human factors in the sampling process, improve the consistency and reliability of sampling, and avoid personnel from contacting potentially harmful or dangerous samples, thereby improving work safety and ensuring the integrity and reliability of data.

The suction nozzle 65 is funnel-shaped, which can improve the dust adsorption capacity of the connecting suction pipe 66 and facilitate the use of the device.

[0044] The working principle of the present invention is as follows: during use, when sampling is required, the sealing rubber sleeve 8 at the bottom of the cover body 7 can be attached to the wall or ground between the required sampling areas, and the first motor 22 can be started to drive the screw rod 23 inside the side rail 21 to rotate. The rotation of the screw rod 23 can assist in driving the slider 24 to slide inside the side rail 21, and by driving the slider 24 to slide downward, the sampling drill bit 33 can be assisted in adjustment and driven to move downward. At this time, the second motor 32 at the top of the disc 31 is started to operate, and the sampling drill bit 33 at the bottom of the disc 31 is driven to rotate by the second motor 32. As the sampling drill bit 33 moves downward to contact the wall or ground for sampling, the sampling drill bit 33 rotates, and the ground or wall can be drilled, prompting the concrete to form powder, so that the device has an automatic sampling function during use, which is convenient for quickly collecting concrete samples.

[0045] A power mechanism 5 is arranged to cooperate with a collecting mechanism 6. During use, the suction fan 53 on the top of the hollow top seat 51 can be started to operate, and the suction fan 53 can be used to generate suction force, so as to cause negative pressure to be generated in the internal cavity of the hollow top seat 51. At this time, the negative pressure in the cavity can assist in absorbing the cement fly ash diffused in the shell 1 through the connecting pipe 4 and the connecting suction pipe 66. The fly ash is sucked into the interior of the collecting box 61 through the connecting suction pipe 66, so that the device can quickly collect concrete cement fly ash. In addition, during the collection process, since a solenoid valve 54 is provided at the input end of the connecting pipe 4, the input end of the connecting pipe 4 can be switched on and off according to the collection needs. During the sample collection period, the solenoid valve 54 at the corresponding position can be opened, so that dust and debris can be introduced into the interior of the collecting mechanism 6. When it is necessary to collect cement samples at different positions again, it is only necessary to start and open another set of solenoid valves 54, so that the device can sample samples at multiple positions at one time, and the overall sample sampling is more convenient, the operation is more convenient, and the use cost is lower.

[0046] A collecting mechanism 6 is provided. When the dust is sucked into the collecting box 61 through the connecting suction pipe 66, the air can flow upward from the bottom to the top, and the one-way plate 633 inside the filter frame 631 can be pushed open by air pressure. The one-way plate 633 rotates to carry the air ash entrained with the cement fly into the filter frame 631. The cement sample is filtered with the assistance of the filter mesh 632 inside the filter frame 631, and the cement ash can be collected in the filter frame 631. In the collection process, when the cement fly ash sample is collected, the electromagnetic valve 54 at the corresponding position is closed. At this time, the connecting pipe 4 loses the suction force, and the magnetic plate 64 adsorbs the one-way plate 633 to close the bottom of the filter frame 631, so that the dust can be prevented from falling off from the bottom, making the device easy to collect fly ash. The design of the collecting mechanism 6 integrated in the shell 1 can automatically store the cement sample during use, so that the device only needs to be carried during use without carrying an external container. The overall operation is relatively convenient and easy to use. By setting the limit assembly 62, when the cement sample needs to be taken out during use of the device, the limit spring 623 can be stretched by pulling the connecting rod 624, and the sealing seat 625 pulls the frame 626 out of the collection box 61. At the same time, as the frame 626 moves outward, the filter frame 631 can be pulled out from the inside of the collection box 61. Since a magnetic plate 64 is also provided inside the frame 626 above the sealing plate, the entire filter frame 631 can be adsorbed by the magnetic plate 64. When the filter frame 631 is moved out of the collection box 61, the filter frame 631 can be taken out. At this time, a new filter frame 631 is inserted into the frame 626, and the limit frame 627 is adsorbed by the magnetic plate 64 in the frame 626. The limit spring 623 at the connecting rod 624 is released to reset, and the filter frame 631 can be reinserted into the collection box 61, so that the device is convenient for quickly replacing the limit frame 627, so that the overall operation of the device can replace the filter frame 631, and it is more convenient to collect cement samples.
