Description

Technical Field

[0001] This utility model relates to the field of hydrophobicity testing, and in particular to a hydrophobicity testing device for rock wool boards. Background Technology

[0002] Rock wool board is an inorganic thermal insulation material made from natural rocks such as basalt and diabase, which are melted at high temperatures, fiberized, and then pressed. Its core advantages lie in its thermal insulation and fire resistance. It has a low thermal conductivity, effectively blocking heat transfer, and is classified as a Class A non-combustible material, meaning it does not burn or release toxic gases when exposed to fire, ensuring high fire safety. Rock wool board also possesses good sound insulation and chemical stability, resisting acid and alkali corrosion and resisting aging and deterioration. It is widely used in building exterior wall insulation, roof insulation, and interior partitions, meeting building energy-saving requirements while improving the safety and comfort of spaces.

[0003] The rock wool board water repellency tester is a specialized device for testing the water permeability resistance of rock wool boards. It mainly consists of a water spraying device and a sample frame. The water spraying device includes a metal nozzle with uniform small holes, and the sample frame can fix the rock wool board at a 45° angle. During the test, the sample is sprayed with water at a uniform speed through the nozzle for a specified time. The mass change before and after spraying is precisely measured, and the volume percentage of the impermeable part is calculated to quantify the water repellency performance. This provides data support for the selection and quality control of rock wool boards in building insulation and other scenarios.

[0004] Existing rock wool board hydrophobicity testers have limitations in accurately adjusting the distance between the nozzle and the rock wool board. This distance directly determines the uniformity, impact force, and coverage of the sprayed water flow. If the distance is too close, the water flow will be too strong in some areas, while if it is too far, the spray may be insufficient. This situation will change the water absorption state of the rock wool board surface, ultimately causing the test data to deviate from the true hydrophobicity performance and failing to provide a reliable basis for product quality judgment. Therefore, a rock wool board hydrophobicity test device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rock wool board hydrophobicity testing device, which aims to improve the function of the existing rock wool board hydrophobicity testing device, which is difficult to accurately adjust the distance between the nozzle and the rock wool board. This distance directly determines the uniformity, impact force and coverage of the spray water flow. If the distance is too close, the local water flow will be too strong, and if it is too far, it may lead to insufficient spraying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rock wool board hydrophobicity testing device, comprising a hydrophobicity testing instrument body, wherein a portable fixing structure is provided inside the hydrophobicity testing instrument body; the portable fixing structure includes a base, a bracket fixedly connected to the side of the base, an installation frame fixedly connected to the side of the bracket, a sliding frame fixedly connected to the side of the base, a fixing bolt threaded inside the sliding frame, a water tank threaded to the side of the sliding frame, a fixing screw threaded inside the sliding frame, a sliding plate slidably connected inside the sliding frame, a handle rotatably connected inside the sliding plate, a rotating rod fixedly connected to the side of the handle, a retractable water pipe fixedly connected to the side of the water tank, a nozzle fixedly connected to the side of the retractable water pipe, and a clamping structure provided inside the installation frame.

[0007] As a further description of the above technical solution: an external water pipe is fixedly connected to one side of the water regulating tank, and an adjusting handle is fixedly connected to the other side of the water regulating tank. The clamping structure includes a frame, a double-ended screw is threadedly connected inside the frame, a bevel gear one is fixedly connected through the double-ended screw, a sliding block is slidably connected inside the frame, a clamping block is fixedly connected to the side of the sliding block, a handle is rotatably connected inside the frame, and a bevel gear two is fixedly connected to the side of the handle.

[0008] As a further description of the above technical solution: the water regulating tank has a threaded groove inside, and the size of the threaded groove inside the water regulating tank matches that of the fixing bolt.

[0009] As a further description of the above technical solution: the sliding plate has a threaded groove inside, and the size of the threaded groove inside the sliding plate matches that of the fixing screw.

[0010] As a further description of the above technical solution: the sliding block has a threaded groove inside, and the threaded groove inside the sliding block matches the size of the bidirectional screw.

[0011] As a further description of the above technical solution: the first bevel gear and the second bevel gear are generally perpendicular to each other in meshing.

[0012] As a further description of the above technical solution: the clamping structure is provided with two sets of sliding blocks and multiple sets of clamping blocks inside.

[0013] As a further description of the above technical solution: the retractable water pipe is designed as a sixth-generation all-plastic retractable water pipe.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the rock wool board sample to be tested is first placed stably inside the mounting frame of the equipment body. The height of the nozzle can be precisely adjusted by raising and lowering the sliding plate. When the nozzle height is adjusted to the specific position required for testing, the spray angle needs to be adjusted by rotating the handle on the side of the sliding plate. The spray direction of the nozzle will also be adjusted accordingly. At this time, the nozzle angle is stably fixed. The water flow rate is precisely adjusted to the set flow range by the flow control device inside the water tank. The water flow is transmitted to the fixed nozzle through the telescopic water pipe. Since the nozzle forms a stable fixed structure with the rotating rod, sliding plate and sliding frame, the uneven spray caused by nozzle displacement is effectively avoided. 2. In this utility model, simply rotating the handle will drive the second bevel gear connected to the other side of the handle to rotate synchronously. The rotation of the second bevel gear will directly drive the first bevel gear to rotate as well. The first bevel gear is fixedly connected to the bidirectional screw, and the thread on its surface will mesh with the thread groove inside the sliding block to form a transmission, so that the two sliding blocks can slide smoothly along the inner track of the frame. Then, the clamping block installed on the side of the sliding block will form a uniform and stable clamping force on the rock wool board placed in the installation frame, effectively preventing it from shifting during the test and ensuring the accuracy and validity of the final test data.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-2 This utility model provides an embodiment of a rock wool board hydrophobicity testing device, comprising a hydrophobicity testing instrument body 1, with a portable fixing structure 2 inside the hydrophobicity testing instrument body 1; the portable fixing structure 2 includes a base 21, a bracket 22 fixedly connected to the side of the base 21, a mounting frame 23 fixedly connected to the side of the bracket 22, a sliding frame 24 fixedly connected to the side of the base 21, a fixing bolt 25 threadedly connected to the inside of the sliding frame 24, and a threaded groove inside the water tank 26, the threaded groove inside the water tank 26 matching the size of the fixing bolt 25. This design allows the water tank 26 to be threadedly fixed to the side of the sliding frame 24 by the fixing bolt 25, the water tank 26 threadedly connected to the side of the sliding frame 24, and a fixing screw 27 threadedly connected to the inside of the sliding frame 24. A sliding plate 28 is slidably connected to the fixed screw 27. The sliding plate 28 has a threaded groove inside, and the size of the threaded groove inside the sliding plate 28 matches the size of the fixed screw 27. This design allows the sliding plate 28 to move threadedly on the outside of the fixed screw 27. A handle 29 is rotatably connected inside the sliding plate 28. A rotating rod 210 is fixedly connected to the side of the handle 29. A telescopic water pipe 211 is fixedly connected to the side of the water tank 26. The telescopic water pipe 211 is designed as a sixth-generation all-plastic telescopic water pipe. The sixth-generation all-plastic telescopic water pipe uses upgraded all-plastic material, eliminating the rust problem of traditional metal joints. At the same time, the weight is greatly reduced, and the telescopic performance is optimized. It also has the characteristics of high pressure resistance and anti-torsion. A nozzle 212 is fixedly connected to the side of the telescopic water pipe 211. A clamping structure 3 is set inside the mounting frame 23.

[0018] Reference Figures 3-4An external water pipe 213 is fixedly connected to one side of the water tank 26, and an adjustment handle 214 is fixedly connected to the other side of the water tank 26. The clamping structure 3 includes a frame 31, with a double-ended screw 32 threadedly connected inside the frame 31. A bevel gear 33 passes through and is fixedly connected inside the double-ended screw 32. A sliding block 34 is slidably connected inside the frame 31. The sliding block 34 has a threaded groove inside, and the threaded groove inside the sliding block 34 matches the size of the double-ended screw 32. This design makes the sliding block 34... The screw can move threadedly on the outside of the bidirectional screw 32. A clamping block 35 is fixedly connected to the side of the sliding block 34. The clamping structure 3 has two sets of sliding blocks 34 and multiple sets of clamping blocks 35 inside. The design of the two sets of sliding blocks 34 corresponds to the two sides of the rock wool board. A handle 36 is rotatably connected inside the frame 31. A bevel gear 37 is fixedly connected to the side of the handle 36. The bevel gear 33 and the bevel gear 37 are perpendicularly meshed with each other. This design allows the bidirectional screw 32 to rotate when the handle 36 is rotated.

[0019] Working principle: When using this hydrophobicity tester to test the hydrophobic performance of rock wool boards, the standardized operation procedures must be strictly followed to ensure accurate data. First, the operator shall stably place the rock wool board sample to be tested inside the mounting frame 23 matched with the hydrophobicity tester body 1. In this step, it is necessary to ensure that the rock wool board has no offset or inclination in the mounting frame 23, so as to avoid affecting the test result due to improper position of the sample in the subsequent spraying process. Then, according to the actual thickness of the rock wool board sample, turn the fixing screw 27 installed on one side of the sliding frame 24. Since the fixing screw 27 is threadedly engaged with the inner wall of the sliding frame 24, a longitudinal driving force will be generated during rotation, so as to control the sliding plate 28 sleeved on the fixing screw 27 to slide stably along the vertical track of the sliding frame 24. The spray head 212 assembly is installed directly below the sliding plate 28, and the precise adjustment of the height of the spray head 212 can be realized through the lifting and lowering of the sliding plate 28. After the height of the spray head 212 is adjusted to the specific position required for testing, stop turning the fixing screw 27. At this time, the spraying angle needs to be adjusted by turning the rotating handle 29 on the side of the sliding plate 28. The rotating handle 29 is fixedly connected to the internal rotating rod 210. When the rotating handle 29 is turned, the rotating rod 210 will rotate stably in the preset bearing structure of the sliding plate 28, and the spray head 212 is rigidly connected to the end of the rotating rod 210. With the rotation of the rotating rod 210, the spraying direction of the spray head 212 will be adjusted accordingly. After the angle required for testing is reached, stop turning the rotating handle 29, and the angle of the spray head 212 is stably fixed at this time. Subsequently, the water supply system of the equipment is started, and the water flow rate is precisely adjusted to the set flow range through the flow control device inside the water regulating tank 26. After the adjustment is completed, the water flow is transmitted to the fixed spray head 212 through the telescopic water pipe 211, and the spray head 212 starts to continuously spray the rock wool board sample. The spraying process needs to last for one hour. During this period, since the spray head 212 forms a stable fixing structure with the sliding frame 24 through the rotating rod 210 and the sliding plate 28, position offset will not occur due to water flow impact or slight vibration of the equipment, which effectively avoids the problem of uneven spraying caused by the displacement of the spray head 212, and further leading to the deviation of test data from the real hydrophobic performance of the rock wool board. After the spraying, the operator shall carefully take down the rock wool board sample, immediately use dry crepe paper to quickly and gently absorb the residual water droplets on the surface of the sample, take care to avoid excessive wiping that damages the surface structure of the sample. After the water droplets on the surface are completely absorbed, quickly place the sample on an electronic scale with required precision to weigh its mass, and the hydrophobic performance data of the rock wool board can be obtained through subsequent calculation. The whole operation process not only reflects the characteristics of portability and ease of use of the tester, but also ensures the accuracy and reliability of the test results through multiple fixing structures and precise control design.

[0020] During the hydrophobicity test, after the operator places the rock wool board inside the mounting frame 23, the continuous rinsing of the nozzle 212 often causes the rock wool board to shift within the mounting frame 23. This displacement not only disrupts the stability of the test environment but may also cause the rinsing range of the nozzle 212 to deviate from the preset area, thus leading to deviations in the final hydrophobicity test data and affecting the accuracy and reliability of the test results. To solve this problem, the main body 1 of this hydrophobicity tester is designed with a special clamping and fixing mechanism. In specific operation, the operator only needs to rotate the handle 36 to drive the bevel gear 37 connected to the other side of the handle 36 to rotate synchronously. Since the bevel gear 37 and the bevel gear 33 are in a perpendicular meshing state, the rotation of the bevel gear 37 will directly drive the bevel gear 33 to rotate accordingly. The bevel gear 33 is fixedly connected to the bidirectional screw 32, so the rotation of the bevel gear 33 will further drive the bidirectional screw 32 to rotate stably inside the frame 31. When the bidirectional screw 32 rotates, the threads on its surface engage with the threaded grooves inside the sliding block 34, causing the two sliding blocks 34 to slide smoothly along the inner track of the frame 31. Since the threads on both sides of the bidirectional screw 32 rotate in opposite directions, the two sliding blocks 34 will gradually move closer to each other during the sliding process. Then, the clamping blocks 35 installed on the side of the sliding blocks 34 will form a uniform and stable clamping force on the rock wool board placed in the mounting frame 23, firmly fixing the rock wool board in the preset position, effectively preventing it from shifting during the test, and ensuring the accuracy and validity of the final test data.
