Description

Technical Field

[0001] The invention relates to the technical field of building detection, in particular to an exterior wall detection device. Background Art

[0002] Building facades are divided into building exterior facades and building interior facades. Building exterior facades are also building exterior walls. Existing building exterior walls need to have good heat insulation and waterproof functions. Therefore, inspection of building exterior walls is essential. After the construction of the building exterior walls is completed, construction workers need to use water to test the paint on the dried walls. Traditional water resistance testing generally uses a nozzle to wash the wall, but excess water will flow directly to the opposite side, causing the ground to be muddy and wasting water resources. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN212254975U discloses a building exterior wall detection device, which includes a base, universal wheels are arranged at the four corners of the lower wall of the base, a box is arranged at the upper end of the base, a mounting slot is arranged in the base, a lifting structure is arranged in the mounting slot, the right wall of the box is open, a support plate is arranged on the left wall of the box, the front and rear walls of the support plate are respectively fixedly connected to the front and rear walls of the box, a water tank is arranged on the left side of the upper wall of the support plate, a water outlet pipe is connected to the lower end of the right wall of the water tank, a water outlet pipe is connected to a water pump away from the end of the water tank, and a connecting pipe is connected to the water outlet of the water pump. The building exterior wall detection device has a simple structure and a reasonable design. Through the cooperation of the baffle and the water collecting tank, water resources can be recycled to prevent excess water from flowing directly to the ground and causing muddy ground. Water resources can be saved by recycling water.

[0004] Although the equipment in the above document can partially recycle the sprayed water by using the baffle to reduce waste, it still has obvious defects in actual use, such as: In daily use, a lot of dust and granular impurities will adhere to the surface of the building's exterior walls. Although the equipment collects water, the water mixed with impurities and dust will not only damage the water pump, but also make the internal impurities of the equipment too muddy, which is inconvenient for subsequent cleaning and cannot meet the current use; Therefore, a kind of exterior wall detection device that can be convenient to use is designed to solve this type of defect.

After the bow-shaped shovel plate is lowered to the bottom, it can also limit and fix the water filter screen to avoid shaking during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] When in use, push the device as a whole to a position close to the wall, then use the self-locking function of the universal wheel at the bottom to fix the device, and then start the dual-axis motor 117 to drive the two rotating rods 118 to rotate. When the rotating rod 118 rotates, it will drive the winding drum 119 on the surface to rotate synchronously, and when the winding drum 119 rotates, it will reel in the cable 120. At this time, the cable 120 pulls the L-shaped sliding rod 202 and the entire protective top frame 201 to rise under the guidance of the guide wheel 116. The cooperation between the supporting vertical rod 114 and the L-shaped sliding rod 202 can make the protective top frame 201 more stable when rising. When the protective top frame 201 rises, it will first pull the lifting vertical rod 207 synchronously through the L-shaped sliding rod 202. Since the curved slide plate 209 and the rectangular vertical groove 208 are slidably connected, the curved slide plate 209 and the arc guide frame 210 will not be pulled up together.

[0023] Please refer to Figure 6 , Figure 7 and Figure 8 , showing the overall structure of the spraying and lifting mechanism 2, the spraying and lifting mechanism 2 includes a protective top frame 201, and the protective top frame 201 is located on the upper side of the inside of the exposed liquid storage tank 102, the lower parts of both sides of the rear part of the protective top frame 201 are fixedly connected with L-shaped sliding rods 202 used in conjunction with the support vertical rod 114 through fixed plates, the two L-shaped sliding rods 202 are respectively slidably connected to the support vertical rod 114 on the same side, one end of the two cables 120 are respectively fixedly connected to the L-shaped sliding rods 202 on the same side, and the cables 120 are fitted with the inner side of the guide wheel 116, the main water pipe 203 is fixedly connected between the two sides of the inner cavity of the protective top frame 201, and both ends of the main water pipe 203 pass through the protective top frame 201 and extend to both sides of the protective top frame 201, the water pipe 113 and the main water pipe 203 on the same side One end of the main water pipe 203 is fixedly connected, the bottom of the main water pipe 203 is fixedly connected with a branch water pipe 204 through an opening, and a plurality of branch water pipes 204 are provided, the surface of the branch water pipe 204 is fixedly connected with an inclined nozzle 205 through an opening, and a plurality of inclined nozzles 205 are provided, a bow-shaped shovel plate 206 used in conjunction with the water filter screen 108 is fixedly connected between the two L-shaped sliding rods 202 through a fixed block, one side of the L-shaped sliding rod 202 is fixedly connected with a lifting vertical rod 207 through a bracket, a rectangular vertical groove 208 is provided on one side of the lifting vertical rod 207, a curved slide plate 209 is slidably installed on the inner side of the rectangular vertical groove 208 and on the surface of the lifting vertical rod 207, and an arc guide frame 210 used in conjunction with the guide push rod 107 is fixedly connected to the bottom of the curved slide plate 209.

[0024] As the protective top frame 201 continues to rise until the bow-shaped shovel plate 206 rises to the upper side of the water filter screen plate 108 and does not block the water filter screen plate 108, at this time, the bottom end of the lifting vertical rod 207 also contacts the curved slide plate 209, and then the protective top frame 201 drives the lifting vertical rod 207 to pull the curved slide plate 209 and the curved guide frame 210 to rise. At this time, the rising curved guide frame 210 will use the inclined surface to squeeze the guide push rod 107. After the guide push rod 107 is squeezed, the limit of the guide slide groove 105 is used to push the water receiving baffle frame 106 through the front telescopic opening 103 to move forward. , and the forward movement of the water receiving baffle frame 106 will pull the water filter screen 108 to flip into a flat state, and then pull it into the inner side of the empty liquid storage tank 102 from the rear telescopic opening 104. When the protective top frame 201 rises to the top, the dual-axis motor 117 stops rotating and uses the self-locking property to fix the protective top frame 201. At the same time, the front end of the water receiving baffle frame 106 is attached to the wall, and a part of the water filter screen 108 is located on the inner side of the empty liquid storage tank 102, and another part is located at the rear of the empty liquid storage tank 102. At this time, the water pump 112 starts to pump the water in the inner cavity of the empty liquid storage tank 102 The water is discharged through the water delivery pipe 113 and injected into the main water pipe 203. Then, the water is sprayed on the wall through the diversion pipe 204 and the inclined nozzle 205. Then, the water flows downward along the wall. After the water contacts the water receiving baffle frame 106, it is directed to the top of the water filter screen 108. At this time, the water filter screen 108 filters the flowing water, so that the water with impurities removed re-enters the interior of the empty liquid storage tank 102 for use. When the spraying time is up, the water pump 112 is turned off to stop spraying water, and then the double-axis motor 117 is started to reverse the winding drum 119 so that the cable 120 can move the protective The top frame 201 descends, and as the protective top frame 201 descends, the arc guide frame 210 also descends and slowly separates from the guide support rod 107. At this time, the water receiving baffle frame 106 moves backward under the elastic force of the spring 110 and retracts to the inside of the empty liquid storage tank 102. After the water receiving baffle frame 106 is completely reset, the water filter mesh plate 108 extends out of the rear telescopic opening 104 and then flips its direction. When the protective top frame 201 is completely dropped to the bottom, it will push the bow-shaped shovel plate 206 to remove impurities on the surface of the water filter mesh plate 108 to avoid drying and clogging, and then the wall after spraying water is tested for water seepage.
