Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete deterioration research, and particularly relates to a concrete deterioration test device. BACKGROUND

[0002] Concrete surface defects are common problems in the engineering field, including exposed reinforcement, honeycomb, voids, clinker, loose, cracks, etc. These defects not only affect the appearance, but more seriously, they can reduce the structural performance and durability of concrete, posing a threat to engineering safety. Therefore, it is of great significance to conduct in-depth research on the causes and prevention of concrete surface defects. The causes of concrete surface defects are complex and diverse, involving materials, construction, environment, and other aspects. Material factors include the mix proportion of concrete, the properties of aggregates, the quality of cement, etc.; construction factors involve concrete mixing, transportation, pouring, vibration, curing, etc. Environmental factors include external conditions such as temperature, humidity, wind speed, etc. Studying how these factors interact to cause defects is the key to preventing defects. Measures to prevent concrete surface defects need to be taken throughout the construction process. For example, optimizing the mix proportion of concrete, selecting appropriate aggregates, and ensuring cement quality are the foundation; during construction, strictly controlling concrete mixing, transportation, reasonably arranging pouring sequence, ensuring adequate vibration, and avoiding missed vibration are the key; finally, scientifically curing concrete, maintaining appropriate temperature and humidity, and avoiding premature form removal or freezing are also indispensable steps. Studying the causes and prevention of concrete surface defects aims to improve the quality and safety of concrete engineering by understanding the key factors that affect defect formation and proposing effective prevention and management strategies. This research not only has direct guiding significance for engineering practice, but also promotes the development of related theories and contributes to the progress of concrete material science.

[0036] Embodiment 2:

[0037] Referring to Figures 1 to 7 In combination with the technical solution of embodiment 1, in the embodiment, the elastic member 6 is a tension spring, the tension spring is connected with the adjusting block 5 and is used for driving the adjusting block 5 to move away from the branch pipe 41.

[0038] Specifically, the adjusting mechanism 7 comprises a circular frame 71 and an arc-shaped plate 72, each adjusting block 5 is provided with an adjusting rod 51, the circular frame 71 is coaxially arranged with the mounting cylinder 2, the elastic member 6 drives the adjusting block 5 to elastically abut on the circular frame 71 or the arc-shaped plate 72, the arc-shaped plate 72 is arranged on the inner side of the circular frame 71 and close to the back of the test box 1, and the arc-shaped plate 72 is used for cooperating with the rotation process of the mounting cylinder 2 to push the adjusting rod 51 to drive the adjusting block 5 to block the branch pipe 41.

[0039] Specifically, the arc-shaped plate 72 is provided with a transition landslide 721 on both sides for abutting of the adjusting rod 51, and the arc-shaped plate 72 is provided with an arc-shaped slide 722 for abutting of the adjusting rod 51, the transition landslide 721 is used for cooperating with the elastic member 6 to drive the adjusting rod 51 to drive the adjusting block 5 to be close to or away from the branch pipe 41, and the arc-shaped slide 722 is used for keeping the state that the adjusting block 5 blocks the branch pipe 41.

[0040] Working principle:

[0041] When the mounting cylinder 2 drives the sundries to rotate to the back of the test box 1 and continues to rotate, the adjusting rod 51 moves from the inner side of the circular frame 71 to the arc-shaped slide 722 through the transition landslide 721, the adjusting rod 51 drives the adjusting block 5 to be close to the branch pipe 41, when the adjusting rod 51 moves to the arc-shaped slide 722 and continues to move along the arc-shaped slide 722, the adjusting rod 51 does not move relative to the mounting disc 4, that is, the adjusting block 5 keeps the state of blocking the branch pipe 41, the chamber 23 corresponding to the blocked branch pipe 41 is in a state of relieving negative pressure, the sundries at the position are not subjected to the adsorption effect and cooperate with the cleaning mechanism 8 to separate from the mounting cylinder 2, and the cleaning work of the sundries is realized, after the sundries are cleaned, in the process that the mounting cylinder 2 continues to drive the chamber 23 to rotate to the drain groove 15, the adjusting rod 51 moves from the arc-shaped slide 722 to the inner side of the circular frame 71 through the transition landslide 721, under the action of the elastic force of the elastic member 6, the adjusting rod 51 drives the adjusting block 5 to be away from the branch pipe 41, and the state of blocking the branch pipe 41 is relieved, the chamber 23 is in a state of negative pressure under the suction effect of the pump body 91, so that the chamber 23 can normally perform the water pumping and recycling work when rotating to the drain groove 15, that is, the linkage cooperation between the driving mechanism 3, the mounting cylinder 2, the elastic member 6, the adjusting mechanism 7, the plurality of branch pipes 41 and the pump body 91 adjusts the negative pressure state of each chamber 23 of the mounting cylinder 2 to realize the automatic cleaning work of the mounting cylinder 2 and the water pumping work.

[0042] Specifically, the height of the mounting tube 2 is greater than the height of the drainage trough 15. Since the height of the mounting tube 2 is greater than the height of the drainage trough 15, after any chamber 23 on the mounting tube 2 is pumped out of the drainage trough 15, as the chamber 23 rotates upward with the mounting tube 2 and leaves the water surface at the drainage trough 15, the chamber 23 no longer pumps water from the drainage trough 15. Instead, the pump body 91 cooperates with the suction pipe 9 to drain the water in the chamber 23. Then, the chamber 23 moves to the back of the test box 1 to cooperate with the cleaning mechanism 8 and the regulating mechanism 7 to clean impurities. This can reduce the outflow of water from the chamber 23 during the cleaning process and improve the recycling and filtration of the water.

[0046] Specifically, the ventilation mechanism 13 is an electric fan, and the electric fan is electrically connected to the control panel 11 .

[0047] Specifically, the cleaning mechanism 8 includes a collecting box 81, a scraper 82 and a torsion spring 83. The collecting box 81 is arranged on the back of the test box 1, the scraper 82 is rotatably installed on the collecting box 81, and the torsion spring 83 is installed on the scraper 82 and is used to drive one end of the scraper 82 to elastically abut against the mounting tube 2.
