Description

Technical Field

[0001] The present invention relates to the technical field of exterior wall water seepage testing, in particular to a building exterior wall water seepage testing device and an operating method. Background Art

[0002] In the field of construction engineering, water seepage in building exterior walls has always been one of the key factors affecting building quality and durability. In order to accurately evaluate the water seepage resistance of building exterior walls and ensure that the building can effectively resist the intrusion of external moisture such as rainwater during long-term use, building exterior wall water seepage testing equipment came into being.

[0003] Currently, existing building exterior wall water seepage testing devices mainly focus on simulating different water seepage environments. By applying water at a certain pressure and flow rate to the exterior wall surface, they can detect whether there is water seepage on the exterior wall, as well as the specific location and extent of water seepage. Such devices usually have precise water pressure control and water flow regulation functions, and can simulate water seepage conditions in natural environments such as actual rainfall to a certain extent, providing an important basis for the quality inspection of building exterior walls.

[0004] However, the existing building exterior wall water seepage test device has an obvious defect in actual application, that is, there is a lack of pretreatment link for cleaning the exterior wall surface. When the building exterior wall is exposed to the natural environment for a long time, a large amount of dust, debris, loose stains, etc. will accumulate on the surface. These pollutants will not only affect the appearance of the exterior wall, but more importantly, they will seriously interfere with the accuracy of the water seepage test. During the water seepage test, if there are large particles of dust and debris on the surface of the exterior wall, they may block the tiny gaps on the surface of the exterior wall and hinder the normal penetration of water, thereby causing deviations in the test results, which cannot truly reflect the anti-water seepage performance of the exterior wall, further affecting the reliability of the test results.

[0019] The present invention also discloses an operating method of a building exterior wall water seepage testing device, which specifically comprises the following steps:

[0020] Step 1: Double cleaning of exterior walls

[0021] Turn on the servo motor to drive the first bevel gear and the second bevel gear to rotate. The two rotating rods drive the roller to perform preliminary cleaning of the outer wall through a series of transmission rods 319, the first synchronous pulley transmission assembly 318, and the second synchronous pulley transmission assembly 320. At the same time, the first bevel gear drives the third bevel gear and other transmissions to enable the cleaning brush to perform secondary cleaning of the outer wall.

[0022] Step 2: External wall water seepage test

[0023] After the exterior wall is cleaned, turn on the pump and deliver the water in the water tank to the sprinkler head through the pipe. Use the sprinkler head to spray the exterior wall surface to conduct the exterior wall water seepage test.

[0024] Step 3: Water collection and recycling

[0025] Turn on the drive motor to drive the wiping roller to rotate and absorb and collect the spray water. The squeezing rod periodically squeezes the wiping roller to drain water; the knocking rod moves up and down to clean the particles on the surface of the wiping roller and knocks the filter; the water and particles generated by squeezing and cleaning fall into the filter, and the filtered water can be reused.

[0026] Compared with the existing technology, it has the following beneficial effects:

[0027] During the initial cleaning stage, the rotation of the drum can remove larger particles of dust, debris, and loose stains on the surface of the exterior wall. During the secondary cleaning stage, the rotation of the cleaning brush can penetrate into the tiny gaps and unevenness of the exterior wall surface, and perform more detailed cleaning of the remaining fine dust, stubborn stains, etc. The two cleaning processes cooperate with each other to ensure that all parts of the exterior wall surface are fully cleaned. During the initial cleaning, the larger contact area of the drum can quickly cover a large area of the exterior wall surface and perform preliminary cleaning on the whole. During the secondary cleaning, the cleaning brush can focus on cleaning corners, edges and uneven surfaces that may be missed by the roller, making the cleaning level of the entire exterior wall surface more uniform, and there will be no situation where some areas are clean while some areas still have stains, thereby avoiding affecting subsequent tests.

[0028] By utilizing the squeezing rod to squeeze the wiping roller, moisture contained in the wiping roller can be squeezed out, thereby improving the drying effect of the wiping roller and ensuring that the wiping roller can continuously and effectively absorb and collect excess water on the exterior wall. The squeezing of the wiping roller by the squeezing rod varies periodically. When the protruding rod is not in contact with the curved rod, the squeezing rod moves outward under the elastic force of the second damping spring, and the squeezing force is relatively small at this time. When the protruding rod contacts the curved rod again, the squeezing force increases. This periodic deep squeezing can prevent the wiping roller from being subjected to the same squeezing intensity for a long time, preventing the wiping roller from being damaged by local excessive squeezing, while also ensuring that moisture can be effectively squeezed out at different stages. During long-term use, the wiping roller may deform to a certain extent due to moisture absorption, squeezing, etc. The periodic squeezing generated by the cooperation of the protruding rod and the curved rod and the elastic action of the second damping spring enable the squeezing rod to automatically adapt to the deformation of the wiping roller to a certain extent. When the thickness of the wiping roller is uneven due to local deformation, the squeezing rod can flexibly adjust the squeezing position and force under the action of the spring to ensure uniform squeezing of the wiping roller and ensure the overall drying effect of the wiping roller.

[0029] Through knocking and vibration cleaning, the vibration effect of the knocking rod on the bottom of the wiping roller can destroy the adhesion between the cement particles and the surface of the wiping roller, so that the originally firmly adhered cement particles are loosened and fall off. The knocking and vibration cleaning can promptly remove these cement particles from the surface of the wiping roller, ensuring that the wiping roller always remains in a relatively clean state, thereby avoiding subsequent impact on the absorption of excess water. In addition, the timely removal of cement particles through knocking and vibration cleaning can reduce the friction between the wiping roller and the cement particles, reduce the wear of the wiping roller, extend the service life of the wiping roller, and reduce the maintenance and replacement costs of the equipment; and the vibration cleaning of the filter can remove impurities and particulate matter attached to the surface of the filter, avoid clogging of the filter, and ensure unobstructed water flow. This knocking and vibration cleaning method is not only efficient, but also can continuously maintain the filtration efficiency of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1: Combination Figures 1-8 As shown, the present invention provides a technical solution: a building exterior wall water seepage test device, comprising a mobile frame 1, a movable frame 2 is horizontally arranged on the surface of the mobile frame 1, and a water seepage component 3 for testing the building exterior wall is arranged on the surface of the movable frame 2;

[0041] The water seepage component 3 includes a fixed plate 31 fixedly mounted on the surface of the movable frame 2, with mounting plates 322 fixedly connected to both sides of the surface of the fixed plate 31, and a spray head 324 for spraying the exterior wall is provided on the mounting plate 322, a support plate 330 is fixedly connected to the bottom of the fixed plate 31, and a support frame 331 is fixedly connected to the surface of the support plate 330, and a drive motor 332 is fixedly connected to one side of the support frame 331, and a first movable shaft 333 is fixedly connected to the output end of the drive motor 332, and the first movable shaft 333 is rotatably mounted on the support frame 331, and a wiping roller 334 for absorbing excess water generated by the spraying is fixedly connected to the outer wall of the first movable shaft 333, and a water-absorbing sponge is provided on the outer surface of the wiping roller 334 for absorbing excess water generated by the spraying;

[0042] The support frame 331 is rotatably connected to a second movable shaft 336 , and both ends of the second movable shaft 336 are fixedly connected to second rotating gears 337 . Both ends of the first movable shaft 333 are fixedly connected to first rotating gears 335 that mesh with the second rotating gears 337 .

[0043] A cylinder 338 is fixedly connected to the outer wall of the second movable shaft 336. A rectangular groove 339 is formed in a circumferential array on the surface of the cylinder 338. A row of cross bars 340 are fixedly connected to the inner wall of the rectangular groove 339. The cross bars 340 are slidably connected to the extrusion rods 341, and the ends of the extrusion rods 341 are slidably installed in the rectangular groove 339. A second damping spring 342 is sleeved on the outer wall of the cross bar 340.

[0044] The cylinder 338 is rotatably connected to a ring 344 fixedly mounted on the support frame 331 on both sides. The inner wall of the ring 344 is provided with a plurality of arc-shaped rods 345 in a circular array. The two ends of the extrusion rod 341 are fixedly connected to a protruding rod 343, and the positions of the protruding rod 343 and the arc-shaped rod 345 correspond to each other.

[0045] By turning on the driving motor 332, the first movable shaft 333 and the wiping roller 334 are driven to rotate synchronously, so that the wiping roller 334 absorbs and collects the water sprayed onto the exterior wall. When the first movable shaft 333 rotates, it drives the first rotating gear 335 to rotate synchronously, so that the first rotating gear 335 drives the meshed second rotating gear 337 to rotate in the opposite direction, so that the second rotating gear 337 drives the second movable shaft 336, the cylinder 338, and the squeezing rod 341 to rotate synchronously, so that the squeezing rod 341, which rotates in the opposite direction to the wiping roller 334, squeezes the wiping roller 334. In this way, the moisture contained in the wiping roller 334 can be squeezed out, the drying effect of the wiping roller 334 can be improved, and the wiping roller 334 can continuously and effectively absorb and collect water on the outer wall; and the cylinder 338 drives the extrusion rod 341 and the convex rod 343 to rotate synchronously during the rotation process. When the convex rod 343 rotates to the position of the arc rod 345, under the action of the arc rod 345, the convex rod 343 and the extrusion rod 341 move toward the inside of the cylinder 338 and compress the second damping spring 342. When the convex rod 343 is no longer in contact with the arc rod 345, the elastic force of the second damping spring 342 pushes the extrusion rod 341 to move toward the inside of the cylinder 338. The rod 341 moves outward, and the cooperation between the protruding rod 343 and the curved rod 345 makes the squeezing of the wiping roller 334 by the squeezing rod 341 show a periodic change. When the protruding rod 343 is not in contact with the curved rod 345, the squeezing rod 341 moves outward under the elastic force of the second damping spring 342. At this time, the squeezing force is relatively small; and when the protruding rod 343 contacts the curved rod 345 again, the squeezing force increases. This periodic deep squeezing can prevent the wiping roller 334 from being under the same squeezing strength for a long time, prevent the wiping roller 334 from being damaged due to local excessive squeezing, and at the same time ensure that The wiping roller 334 can be effectively squeezed out at all stages. During long-term use, the wiping roller 334 may be deformed to a certain extent due to water absorption, squeezing, etc. The periodic squeezing generated by the cooperation of the convex rod 343 and the arc rod 345 and the elastic effect of the second damping spring 342 can make the squeezing rod 341 automatically adapt to the deformation of the wiping roller 334 to a certain extent. When the thickness of the wiping roller 334 is uneven due to local deformation, the squeezing rod 341 can flexibly adjust the squeezing position and force under the action of the spring to ensure uniform squeezing of the wiping roller 334 and ensure the overall drying effect of the wiping roller 334.

The sliding plate 348 is fixedly connected to a connecting frame 349, and the end of the connecting frame 349 slides with the side wall of the convex plate 350. 48. The connecting frame 349, the connecting rod 351, and the knocking rod 352 move reciprocatingly up and down, so that the knocking rod 352 knocks the bottom of the wiping roller 334, thereby knocking and vibrating the cement particles stuck on the surface of the wiping roller 334 to clean them. Through the knocking and vibration cleaning, the vibration effect of the knocking rod 352 on the bottom of the wiping roller 334 can destroy the adhesion between the cement particles and the surface of the wiping roller 334, so that the originally firmly stuck cement particles are loosened and fall off. The knocking and vibration cleaning can promptly remove these cement particles from the surface of the wiping roller 334, ensuring that the wiping roller 334 always remains in a relatively clean state, thereby avoiding subsequent influence on the absorption of excess water. In addition, the knocking and vibration cleaning can promptly remove cement particles, which can reduce the friction between the wiping roller 334 and the cement particles, reduce the wear of the wiping roller 334, extend the service life of the wiping roller 334, and reduce the maintenance cost and replacement cost of the equipment.

[0048] A water tank 328 is provided on the surface of the mobile frame 1, and the water tank 328 is located below the wiping roller 334. A filter screen 329 is provided obliquely in the inner cavity of the water tank 328;

By turning on the pump body 326, the pump body 326 draws water out of the water tank 328 through the second connecting pipe 327, and delivers the water to the sprinkler head 324 through the first connecting pipe 325 and the delivery pipe 323. The sprinkler head 324 is used to spray the exterior wall surface, so that the building exterior wall water seepage test can be carried out.

[0050] In the embodiment of the present invention, by turning on the servo motor 311, the first bevel gear 312 and the second bevel gear 313 are driven to rotate synchronously, and the second bevel gear 313 drives the meshed fourth bevel gear 321 and the transmission rod 319 to rotate synchronously, and the transmission rod 319 drives the rotating rod 316 to rotate synchronously through the second synchronous pulley transmission assembly 320, and the rotating rod 316 drives another rotating rod 316 to rotate synchronously through the first synchronous pulley transmission assembly 318, so that the two rotating rods 316 drive the roller 317 to rotate synchronously, so that the roller 317 performs preliminary cleaning of the outer wall surface, and the first bevel gear 312 drives the meshed third bevel gear 315 to rotate, thereby driving the positioning shaft 32 and the driving gear 34 to rotate synchronously, so that the driving gear 34 drives the meshed driven gears 35 and the rotating shaft 33 on both sides to rotate synchronously, so that the rotating shaft 33 drives the disc 38, the telescopic rod 39, and the cleaning brush 37 to rotate synchronously, so that the cleaning brush 37 performs secondary cleaning of the outer wall surface;

[0051] In the initial cleaning stage, the rotation of the roller 317 can remove larger particles of dust, debris, and loose stains on the surface of the exterior wall.

[0052] After the cleaning of the building's exterior wall is completed, the pump body 326 is turned on, and the pump body 326 pumps water out of the water tank 328 through the second connecting pipe 327, and delivers the water to the sprinkler head 324 through the first connecting pipe 325 and the delivery pipe 323.

The cylinder 338 drives the extrusion rod 341 and the convex rod 343 to rotate synchronously during the rotation process. When the convex rod 343 rotates to the position of the arc rod 345, the convex rod 343 and the extrusion rod 341 move toward the inside of the cylinder 338 under the action of the arc rod 345 and compress the second damping spring 342. When the convex rod 343 is no longer in contact with the arc rod 345, the elastic force of the second damping spring 342 pushes the extrusion rod 341 to The pressing rod 341 moves outward, and the cooperation between the protruding rod 343 and the curved rod 345 makes the squeezing of the wiping roller 334 by the squeezing rod 341 show a periodic change. When the protruding rod 343 is not in contact with the curved rod 345, the squeezing rod 341 moves outward under the elastic force of the second damping spring 342. At this time, the squeezing force is relatively small; and when the protruding rod 343 contacts the curved rod 345 again, the squeezing force increases. This periodic deep squeezing can prevent the wiping roller 334 from being under the same squeezing strength for a long time, prevent the wiping roller 334 from being damaged due to local excessive squeezing, and at the same time ensure that The wiping roller 334 can be effectively squeezed out at the same stage. During long-term use, the wiping roller 334 may be deformed to a certain extent due to water absorption, squeezing, etc. The periodic squeezing generated by the cooperation of the convex rod 343 and the arc rod 345 and the elastic effect of the second damping spring 342 can make the squeezing rod 341 automatically adapt to the deformation of the wiping roller 334 to a certain extent. When the thickness of the wiping roller 334 is uneven due to local deformation, the squeezing rod 341 can flexibly adjust the squeezing position and force under the action of the spring to ensure uniform squeezing of the wiping roller 334 and ensure the overall drying effect of the wiping roller 334.

[0054] When the first rotating gear 335 rotates, it drives the convex plate 350 to rotate synchronously, so that the convex plate 350 drives the sliding plate 348, the connecting frame 349, the connecting rod 351, and the knocking rod 352 to move back and forth up and down under the elastic force of the third damping spring 353. When the knocking rod 352 moves upward, it can knock on the bottom of the wiping roller 334, so that the cement particles stuck on the surface of the wiping roller 334 can be knocked and vibrated to clean them. When the knocking rod 352 moves downward, it can knock and vibrate the surface of the filter screen 329. Through the knocking and vibration cleaning, the vibration effect of the knocking rod 352 on the bottom of the wiping roller 334 can destroy the adhesion between the cement particles and the surface of the wiping roller 334, so that the cement particles that were originally firmly stuck can be loosened. The cleaning of the filter 329 by the vibration can remove the impurities and particles attached to the surface of the filter 329, avoid clogging of the filter 329 and ensure unimpeded water flow. This cleaning method of the vibration is not only efficient, but also can continuously maintain the filtration efficiency of the filter 329.

[0055] The water produced by squeezing the wiping roller 334 by the squeezing rod 341 falls onto the filter 329 in the water tank 328, and the cement particles cleaned by the vibration also fall onto the filter 329, which is filtered by the filter 329, so that the filtered water can be reused.

[0056] Example 2: Combination Figure 1 As shown, on the basis of the first embodiment, a forward and reverse motor 11 is fixedly installed on one side of the mobile frame 1, a screw rod 12 is fixedly connected to the output end of the forward and reverse motor 11, and the movable frame 2 is threadedly connected to the screw rod 12, and a guide rod 13 is fixedly connected to both sides of the mobile frame 1, and the movable frame 2 is slidably connected to the guide rod 13. By turning on the forward and reverse motor 11 to drive the screw rod 12 to rotate synchronously, the screw rod 12 drives the movable frame 2 to move laterally on the guide rod 13, thereby driving the water seepage component 3 to move laterally on the outer wall surface;

[0057] Cylinders 14 are fixedly installed on both sides of the mobile frame 1, and the output end of the cylinder 14 is fixedly connected to a bonding plate 15. By opening the cylinder 14, the bonding plate 15 is driven to move toward one side of the outer wall to bond, so that the position of the mobile frame 1 and the water seepage component 3 can be determined.

[0058] In an embodiment of the present invention, the forward and reverse motors 11 are turned on to drive the screw rod 12 to rotate synchronously, and the screw rod 12 drives the movable frame 2 to move laterally on the guide rod 13, thereby driving the water seepage component 3 on the outer wall surface to move laterally. By turning on the cylinder 14, the bonding plate 15 is driven to move toward one side of the outer wall to fit, so that the position of the movable frame 1 and the water seepage component 3 can be determined.

[0059] The present invention also discloses an operating method of a building exterior wall water seepage testing device, which specifically comprises the following steps:

[0060] Step 1: Double cleaning of exterior walls

[0061] The servo motor 311 is turned on to drive the first bevel gear 312 and the second bevel gear 313 to rotate. The two rotating rods 316 drive the roller 317 to perform preliminary cleaning of the outer wall through a series of transmission rods 319, a first synchronous pulley transmission assembly 318, and a second synchronous pulley transmission assembly 320. At the same time, the first bevel gear 312 drives the third bevel gear 315 and other transmissions to cause the cleaning brush 37 to perform secondary cleaning of the outer wall.

[0062] Step 2: External wall water seepage test

[0063] After the exterior wall is cleaned, the pump body 326 is turned on to transport the water in the water tank 328 to the sprinkler head 324 through the pipe. The sprinkler head 324 is used to spray the exterior wall surface to conduct an exterior wall water seepage test.

[0064] Step 3: Water collection and recycling

[0065] The driving motor 332 is turned on to drive the wiping roller 334 to rotate and absorb and collect the spray water. The squeezing rod 341 periodically squeezes the wiping roller 334 to drain water; the knocking rod 352 moves up and down to clean the particles on the surface of the wiping roller 334 and knocks the filter 329; the water and particles generated by squeezing and cleaning fall into the filter 329, and the filtered water can be reused.
