Description

Technical Field

[0001] The present invention relates to the technical field of corrosion resistance detection, and particularly relates to a building material detection device and method. Background Art

[0002] Low-carbon green building materials refer to materials that can significantly reduce the use of petrochemical energy, improve energy efficiency, and reduce carbon dioxide emissions throughout the entire life cycle of building materials, equipment manufacturing, building construction, and building use. These materials not only help relieve the pressure on the environment but also conform to the concept of sustainable development. They usually have the characteristics of long life and easy maintenance to reduce the replacement frequency and maintenance cost of materials. Among them, corrosion resistance detection is particularly important.

[0003] The spray test method is a commonly used method for simulating a corrosion environment. By spraying a specific corrosion medium (such as a salt solution, acid rain, etc.) onto the surface of building materials, the corrosion resistance performance of the materials in a specific environment can be evaluated.

[0004] In the prior art, a salt spray test chamber is one of the commonly used devices for the spray test method. By placing the building materials to be detected in the test chamber and using a nozzle to make the corrosion medium into a mist and spray it onto the surface of the building materials, the corrosion resistance performance is detected. However, the spraying positions of the nozzles are mostly fixed, resulting in differences in the concentration of the corrosion medium near the parts of the building materials close to and far from the nozzles, which affects the detection of the corrosion resistance performance of each part of the building materials.

In addition, terms such as "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0053] In addition, terms such as "identical" do not require the components to be absolutely identical, but there can be minor differences. The term "vertical" only means that the positional relationship between components is more vertical relative to "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0054] Please refer to Figures 1-11 , the present invention provides a technical solution: a building material detection device, including a box body 1 with a hollow structure and an opening on the top wall, and a box cover 2 for covering the opening of the box body 1. One side edge of the box cover 2 is rotatably connected to one side edge of the opening of the box body 1. A placement table 3 for placing building materials is arranged at the lower part inside the box body 1, and the placement table 3 is slidably connected to the inner wall of the box body 1 along the length direction of the box body 1;

[0055] A driving part for driving the placement table 3 to slide inside the box body 1 is arranged on the box body 1;

[0056] A spray pipe 4 with a hollow structure is arranged above the placement table 3. The spray pipe 4 is connected to the inner wall of the box body 1. A water outlet hole 41 is opened on a plane of the spray pipe 4 facing the placement table 3. A medicine tank 5 communicated with the inside of the spray pipe 4 is arranged on the outer wall of the box body 1.

[0057] In this solution, the spray pipe 4 is arranged above the placement table 3. The corrosion medium stored in the medicine tank 5 is sprayed out through the water outlet holes 41 on the spray pipe 4 and in a mist shape, so that the corrosion medium falls on the surface of the building material to be detected for corrosion resistance performance detection; at the same time, the placement table 3 is slidably connected to the box body 1, and the driving part is used to drive the placement table 3 to slide inside the box body 1, so that the building material approaches or moves away from the water outlet holes 41, reducing the concentration difference of the corrosion medium near each part of the building material, so as to facilitate the corrosion resistance performance detection of each part of the building material at the same time.

[0058] Wherein, the bottom surface of the placement table 3 is in contact with the inner bottom surface of the box body 1, and the two side surfaces of the placement table 3 are respectively in contact with the two side walls in the width direction inside the box body 1, restricting the placement table 3 from rotating inside the box body 1, so that the placement table 3 can only move along the length direction of the box body 1.

[0059] In addition, a water guide pipe is arranged at the bottom of the medicine tank 5, and the bottom of the medicine tank 5 and the spray pipe 4 are connected through the water guide pipe to form a channel for the corrosion medium in the medicine tank 5 to enter the spray pipe 4; at the same time, a peristaltic pump or the like can be arranged on the water guide pipe, and the peristaltic pump is used to press the corrosion medium into the spray pipe 4.

[0060] During use, rotate the box cover 2 to open the opening of the box body 1, place the building materials to be tested on the placing table 3, rotate the box cover 2 again to cover the opening of the box body 1, so as to form a closed chamber inside the box body 1. Then inject the corrosive medium into the medicine tank 5, start the peristaltic pump, and press the corrosive medium into the spray pipe 4 through the peristaltic pump. A positive pressure is formed inside the spray pipe 4, so that the corrosive medium is pressed out from the water outlet holes 41 in the form of fine particles, and a large amount of corrosive medium is pressed out and accumulates in a mist shape until it falls on the surface of the building materials to be tested for corrosion resistance performance detection. Drive the placing table 3 to slide inside the box body 1 through the driving part, so that the building materials move closer to or away from the water outlet holes 41 inside the box body 1, reducing the concentration difference of the corrosive medium near each part of the building materials, so as to facilitate the corrosion resistance performance detection of each part of the building materials at the same time.

[0061] In this embodiment: The driving part includes a motor 61 fixedly connected to one end wall outside the box body 1 and a lead screw 62 arranged inside the box body 1. One end of the lead screw 62 penetrates through one end wall of the box body 1 and is fixedly connected to the output end of the motor 61;

[0062] The other end of the lead screw 62 extends along the length direction of the box body 1, penetrates through the placing table 3 and is rotatably connected to the other end wall of the box body 1, and the lead screw 62 is in threaded fit connection with the placing table 3.

[0063] In this solution, as Figure 9 shown, the lead screw 62 penetrates through the placing table 3, restricting the ability of the placing table 3 to move vertically inside the box body 1, so that the placing table 3 can only move along the length direction of the box body 1 inside the box body 1; and the lead screw 62 is in threaded fit connection with the placing table 3, and only by driving the lead screw 62 to rotate uniformly by the motor 61 can the placing table 3 and the building materials on the placing table 3 move smoothly inside the box body 1.

[0064] In addition, by controlling the motor 61 to rotate forward and reverse alternately, the placing table 3 can make a reciprocating linear motion inside the box, and the building materials approach or move away from the water outlet holes 41 periodically, continuously carrying out the corrosion resistance performance detection work.

[0065] Among them, the motor 61 can be selected as Xima Z2-41.

[0066] In this embodiment: The spray pipe 4 is in a long strip shape and is parallel to the lead screw 62. Both ends of the spray pipe 4 are fixedly connected with a first connecting rod 42 and a second connecting rod 43 respectively;

[0067] One end of the first connecting rod 42 is sleeved outside one end of the lead screw 62 facing the motor 61 and is rotatably matched with the lead screw 62;

[0068] One end of the second connecting rod 43 is sleeved outside the other end of the lead screw 62 and is rotatably matched with the lead screw 62;

[0069] The second connecting rod 43 is rotatably connected to the end wall of the box body 1 with the axis of the lead screw 62 as the rotation center, and a locking portion for restricting the rotation of the second connecting rod 43 relative to the box body 1 is provided between the second connecting rod 43 and the end wall of the box body 1.

[0070] In this solution, as Figure 5 , 8 shown, the spray pipe 4, the first connecting rod 42 and the second connecting rod 43 are spliced into a U-shaped structure. The two ends of the first connecting rod 42 and the second connecting rod 43 facing away from the spray pipe 4 are respectively sleeved outside the two ends of the lead screw 62 and are rotationally matched, so that the U-shaped structure can rotate relative to the lead screw 62.

[0071] In addition, the second connecting rod 43 is rotatably connected to the end wall of the box body 1 with the axis of the lead screw 62 as the rotation center, so that the U-shaped structure can rotate on the box body 1. Therefore, the opening direction of the water outlet hole 41 on the spray pipe 4 can be adjusted by driving the second connecting rod 43 to rotate on the box body 1, so that the spraying direction of the corrosive medium can be changed and adjusted, so as to facilitate the detection of a specific surface of the building material. Moreover, the lead screw 62 does not affect the rotation of the second connecting rod 43 on the box body 1.

[0072] Among them, the placing table 3 is arranged between the first connecting rod 42 and the second connecting rod 43.

[0073] In this embodiment: a cylinder 431 coaxial with the lead screw 62 is fixedly connected to the side wall of the second connecting rod 43 facing away from the first connecting rod 42;

[0074] One end of the cylinder 431 penetrates through the end wall of the box body 1 facing away from the motor 61 and extends out of the box body 1, and is rotationally matched with the end wall of the box body 1.

[0075] In this solution, as shown in questions 9 and 10, one end of the cylinder 431 penetrates through the end wall of the box body 1 and extends out of the box body 1, so as to facilitate the control of the rotation of the second connecting rod 43 and adjust the spraying direction of the corrosive medium; moreover, one end of the lead screw 62 facing away from the motor 61 is inserted into the second connecting rod 43, and the lead screw 62 can be supported by the second connecting rod 43, so that the connection between the lead screw 62 and the box body 1 is more stable.

[0076] In this embodiment: an external thread is provided on the outer circumferential surface of the cylinder 431 at one end outside the box body 1, and the locking portion includes a sleeve 432 arranged outside the box body 1, and the sleeve 432 is sleeved outside the cylinder 431 and is connected by thread fit.

[0077] In this solution, as Figure 2 , 3As shown, the sleeve 432 is threadedly engaged with the cylinder 431 to restrict the free movement of the sleeve 432 along the axial direction of the cylinder 431 on the cylinder 431. When it is necessary to lock and fix the cylinder 431, only need to rotate the sleeve 432 forward to make one end face of the sleeve 432 closely fit with the outer end face of the box body 1, and use the frictional force between the sleeve 432 and the box body 1 to restrict the rotation of the sleeve 432 on the cylinder 431.

[0078] When it is necessary to adjust the spraying direction, only need to rotate the sleeve 432 in the reverse direction to make the sleeve 432 disengage from the box body 1, then the cylinder 431 can be controlled to rotate relative to the box body 1. When the spray pipe 4 rotates to the target position, rotate the sleeve 432 forward again to complete the work of adjusting the spraying direction, and the operation is simple and convenient.

[0079] In this embodiment: a atomizing nozzle 44 is rotatably and sealingly engaged in the water outlet hole 41. The atomizing nozzle 44 has a hollow structure with one end open, and the open end is embedded in the spray pipe 4 and communicated with the inside of the spray pipe 4;

[0080] The other end of the atomizing nozzle 44 protrudes out of the spray pipe 4, and atomizing holes 441 communicating the inside and outside of the atomizing nozzle 44 are provided on the side wall;

[0081] A linkage assembly is provided between the atomizing nozzle 44 and the lead screw 62. When the lead screw 62 rotates, the atomizing nozzle 44 is driven to rotate on the water outlet hole 41 through the linkage assembly.

[0082] In this solution, as Figure 11 shown, the atomizing nozzle 44 blocks the water outlet hole 41, so that the atomizing holes 441 serve as the only channel for the corrosive medium in the spray pipe 4 to flow out. The atomizing nozzle 44 is rotatably engaged with the water outlet hole 41, and the centrifugal force generated by driving the corrosive medium to rotate by the atomizing nozzle 44 and the pressure applied by the peristaltic pump to the corrosive medium act together to rotate the corrosive medium out from the atomizing holes 441 to form fine granular corrosive medium, so as to achieve the purpose of atomizing the corrosive medium.

[0083] In this embodiment: the section of the atomizing nozzle 44 outside the spray pipe 4 tapers away from the spray pipe 4 and then forms a conical shape. A plurality of the atomizing holes 441 are provided, and the plurality of atomizing holes 441 are arranged on the curved surface of the atomizing nozzle 44 and are arranged from the tip of the atomizing nozzle 44 towards the direction close to the spray pipe 4.

[0084] In this solution, as Figure 7 shown, by arranging the atomizing holes 441 on the curved surface of the atomizing nozzle 44 and arranging them from the tip of the atomizing nozzle 44 towards the direction close to the spray pipe 4, the distances between the atomizing holes 441 distributed along the axis of the atomizing nozzle 44 and the axis of the atomizing nozzle 44 are different, that is, the corresponding rotation radii of the atomizing holes 441 are different, and the centrifugal forces of the ejected corrosive medium are different, increasing the coverage range of the corrosive medium ejected by the atomizing nozzle 44.

[0085] In this embodiment, a plurality of water outlet holes 41 are provided, and atomizing nozzles 44 are rotatably fitted on each of the plurality of water outlet holes 41. A driven bevel gear 442 is coaxially and fixedly connected to the open end of each of the plurality of atomizing nozzles 44;

[0086] A transmission shaft 45 parallel to the spray pipe 4 is arranged in the spray pipe 4, and both ends of the transmission shaft 45 are inserted into the end walls of both ends of the spray pipe 4 and are hermetically and rotatably fitted. A plurality of driving bevel gears 451 corresponding to the plurality of driven bevel gears 442 one by one are coaxially and fixedly connected to the transmission shaft 45;

[0087] The driving bevel gear 451 meshes with the driven bevel gear 442, and there is a gap between the outer circumferential surface of the driving bevel gear 451 and the inner wall of the spray pipe 4.

[0088] In this solution, as Figure 5 , 9 shown, a plurality of atomizing nozzles 44 are arranged along the length direction of the spray pipe 4 (the length direction of the box body 1). Through the transmission shaft 45, the plurality of driving bevel gears 451 and the plurality of driven bevel gears 442, the plurality of atomizing nozzles 44 are associated, so that the plurality of atomizing nozzles 44 rotate synchronously, at the same speed and in the same direction for atomizing work, so as to reduce the concentration difference of the corrosive medium at each position in the length direction of the box body 1, and further reduce the error of the corrosion resistance performance detection of building materials.

[0089] Among them, there is a gap between the outer circumferential surface of the driving bevel gear 451 and the inner wall of the spray pipe 4, and the corrosive medium can pass through this gap, so that the corrosive medium can freely flow in the spray pipe 4, so as to facilitate injecting the corrosive medium into the plurality of atomizing nozzles 44 at the same time.

[0090] In this embodiment, one end of the transmission shaft 45 facing the motor 61 penetrates through the end wall of the spray pipe 4 and extends outside the spray pipe 4. The linkage assembly is a driven sprocket 452 coaxially and fixedly connected to one end of the transmission shaft 45 outside the spray pipe 4, and a driving sprocket 621 coaxially and fixedly connected to one end of the lead screw 62 facing the motor 61;

[0091] A chain 7 is commonly wound and meshed outside the driving sprocket 621 and the driven sprocket 452.

[0092] In this solution, by adjusting the transmission ratio between the lead screw 62 and the placement table 3, the transmission ratio between the driving sprocket 621 and the driven sprocket 452, and the transmission ratio between the driving bevel gear 451 and the driven bevel gear 442, when the atomizing nozzle 44 rotates at a high speed on the spray pipe 4 for spraying work, the placement table 3 drives the building materials to slowly move in the box body 1. Moreover, only by controlling the rotation of the motor 61 can the detection device run smoothly, simplifying the operation steps.

[0093] A method for detecting building materials, including using the above-mentioned building material detection device, the detection method is as follows:

[0094] S1. Place the building materials to be detected stably on the tabletop of the placement table 3, inject the corrosive medium into the medicine tank 5, and the corrosive medium flows into the interior of the spray pipe 4 through the pipeline between the medicine tank 5 and the spray pipe 4 and enters the atomizing nozzle 44;

[0095] S2. Loosen the sleeve 432, the sleeve 432 is disengaged from the outer wall of the box body 1, the cylinder 431 is in a freely rotatable state on the box body 1, rotate the cylinder 431 on the box body 1 to drive the first connecting rod 42, the second connecting rod 43 and the spray pipe 4 to swing on the lead screw 62, adjust the spraying angle of the spray pipe 4, then tighten the sleeve 432, and rotate the box cover 2 to cover the opening of the box body 1;

[0096] S3. Use the driving part to drive the placement table 3 and the building materials on the placement table 3 to move in the box body 1, so that each part of the building materials approaches or moves away from the water outlet hole 41.
