Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically to a building wall deformation monitoring device. Background Technology

[0002] Building walls come in a wide variety of types, each with its own characteristics. Load-bearing walls support the main load and are typically constructed of brick, concrete, or masonry; non-load-bearing walls are used for space partitioning, and are made of materials such as lightweight partition panels or gypsum board. Brick walls are constructed of bricks and are highly durable; concrete walls have high strength and are suitable for high-rise buildings. Drywalls are made of gypsum board and are easy to construct; lightweight partition walls use lightweight materials and are suitable for interior partitions. Composite walls consist of layers of different materials to improve thermal and sound insulation performance.

[0003] Various types of walls can deform under special circumstances. Wall deformation may be caused by the following reasons: uneven load distribution, structural design defects, construction quality problems, material aging or damage, foundation settlement or displacement, and thermal expansion and contraction caused by temperature changes. Wall deformation may lead to structural safety hazards, cracks and wall damage, doors and windows that cannot be opened or closed properly, reduced building durability, and may affect the functionality and comfort of use. Therefore, it is necessary to inspect the walls regularly to avoid damage caused by wall deformation. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figures 1 to 7 A building wall deformation monitoring device, comprising:

[0027] The frame 1 has a phase change material capsule 5 embedded in its inner wall. Heating devices are fixedly installed on both sides of the inner wall of the phase change material capsule 5. The phase change material capsule 5 is filled with phase change material, which can be materials such as paraffin that melt at high temperatures and solidify at low temperatures.

[0028] The extrusion assembly 2 is used to extrude phase change materials. The extrusion assembly 2 includes a rotating column 206, with an air injection port 208 sleeved on the outer wall of the rotating column 206 and at least one air bladder 207 opened on the inner wall of the rotating column 206. The rotating column 206 is connected to the air injection port 208 through the air bladder 207. The rotating column 206 and the air injection port 208 are driven to move up and down. The extrusion assembly 2 also includes an output end 304 and a receiving end 305. The output end 304 and the receiving end 305 are driven to move up and down. With the setting of the air bladder 207, the air bladder 207 can expand by filling gas inside and extrude the phase change materials.

[0029] Reference Figures 3 to 6An electromagnetic plate 201 is fixedly installed on one side of the lower part of the frame 1. The electromagnetic plate 201 is connected to an external power supply. A C-shaped frame 202 is fitted on the outer side of the electromagnetic plate 201. A drive source is fixedly installed on the upper end of the C-shaped frame 202. The output end of the drive source passes through the C-shaped frame 202 and is fixedly connected to a screw 203. The screw 203 is rotatably connected to the C-shaped frame 202. A lifting frame 204 is fitted on the outer periphery of the screw 203. Two rotating clamping plates 205 are symmetrically installed inside the lifting frame 204. The two rotating clamping plates 205 are rotatably connected to a rotating column 206. Two air inlet pipes 209 are fixedly installed on one side of the back. The inner diameter of one of the two air inlet pipes 209 is smaller than that of the other. The outer wall of the air inlet pipe 209 passes through the lifting frame 204 and is fixedly connected to the first gear 210. An air injection cylinder 211 is fixedly installed on the side of the first gear 210 away from the rotating clamp 205. A sliding plate 214 is slidably installed on the inner wall of the air injection cylinder 211. The sliding plate 214 is driven to slide on the inner wall of the air injection cylinder 211. After the electromagnetic plate 201 is connected to an external power source, it can generate magnetism to attract the C-shaped frame 202, thereby fixing the C-shaped frame 202 to one side of the phase change material.

[0030] Reference Figure 6 A second gear 215 is rotatably mounted on one side of the lifting frame 204, away from the air cylinder 211. A reciprocating screw 217 is fixedly mounted on the side of the second gear 215 away from the lifting frame 204. A matching movable sleeve 216 is sleeved on the outer circumference of the reciprocating screw 217. The movable sleeve 216 is composed of a sleeve and a U-shaped frame. An L-shaped connecting frame 218 is fixedly mounted on one side of the U-shaped frame, away from the second gear 215. One end of the L-shaped connecting frame 218 is fixedly connected to the slide plate 214. When the reciprocating screw 217 is driven to rotate, it will drive the slide plate 214 to rotate synchronously, so that the slide plate 214 slides inside the air cylinder 211, squeezing air into the airbag 207.

[0031] Reference Figure 7 It also includes a measuring component 3, which includes a linear drive device 301 fixedly installed on one side of the frame 1. Two vertical plates 302 are symmetrically installed on the upper end of the driving end of the linear drive device 301. A horizontal plate 303 is fixedly installed on the side of the two vertical plates 302 away from the linear drive device 301. The vertical plates 302 are fixedly connected to the output end 304. The horizontal plate 303 is fixedly connected to the receiving end 305 at one end away from the vertical plates 302. An alarm device is connected to the output end 304 and the receiving end 305.

[0032] Reference Figure 2It also includes a movable component 4, which includes two connecting plates 401 symmetrically installed on one side and at a lower position of the frame 1. A handle 403 is fixedly installed on the upper end of the two connecting plates 401, and two sets of casters 402 are fixedly installed on the lower end of the two connecting plates 401 respectively.

[0033] The working principle of this utility model is as follows:

[0034] By pushing the handle 403, the caster 402 rotates, causing the connecting plate 401 and frame 1 to move closer to and fit against the wall. The heating device inside the phase change material capsule 5 (which can be powered by an external power source) is activated, melting the phase change material. The phase change material melts to a semi-molten state. When it reaches this semi-molten state, the electromagnetic plate 201 is magnetized by an external power source, attracting the C-shaped frame 202. At this point, the C-shaped frame 202 is on one side of the phase change material. The drive source is activated, causing the screw 203 to rotate. During this rotation, the screw 203 drives the lifting frame 204 to rise and fall. This rise and fall causes the first gear 210 to mesh with the gear plate 219 and rotate. The first gear 210 then meshes with the second gear 215, causing the second gear 215 to rotate. During the rotation, the reciprocating screw 217 will rotate. The reciprocating screw 217 is matched with the moving sleeve 216 and will drive the moving sleeve 216 to move back and forth. Therefore, when the moving sleeve 216 moves back and forth, it will drive the slide plate 214 to move back and forth inside the air cylinder 211, and squeeze the air into the rotating column 206 through the one-way valve 213 and the rotating clamp 205. When the moving sleeve 216 moves back and forth, the external air will flow from the air inlet 212 into the air cylinder 211, and then be pushed into the rotating column 206 as the slide plate 214 moves back and forth. It should be noted that when the air is pushed into the rotating column 206, it will flow out through the smaller diameter air inlet pipe 209. The larger diameter air inlet pipe 209 will create a difference in air volume. The air that cannot flow out through the smaller diameter air inlet pipe 209 will flow into the airbag 207 from the air inlet 208.

[0035] The inflated airbag 207 contacts and compresses the phase change material bag 5, causing the molten phase change material to adhere to the wall. The wall's depressions and protrusions are imprinted onto the deformable material. After heating stops, the phase change material solidifies from a semi-molten state, thus imprinting the wall's depressions and protrusions onto the phase change material. After imprinting is complete, the external power supply is turned off, causing the electromagnetic plate 201 to lose its magnetism and the C-shaped frame 202 to be removed. The linear drive device 301 then drives the two vertical plates 302 to rise and fall, opening the output end 304. The output end 304 emits a laser with a receiver 3. 05. The two sets of output terminals 304 and receiver terminals 305 will rise and fall on both sides of the phase change material (it should be noted that the distance between the output terminals 304 and receiver terminals 305 and the phase change material can be adjusted, and the distance between the output terminals 304 and receiver terminals 305 can allow the wall to have a certain degree of protrusion and depression). The phase change material that is pressed out due to the deformation of the wall will block the laser emitted by the output terminal 304, so that the receiver terminal 305 cannot receive the laser. In this way, the output terminal 304 will send a signal to the alarm device to sound an alarm, thereby determining whether the wall is deformed.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
