DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings: The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0020] like Figures 1 to 3 As shown, a building exterior wall water seepage testing device includes a body 100, a power arm 200, a water pump 300, an external delivery pipe 400, and a detection component 500. The water pump 300 and the external delivery pipe 400 are respectively installed in the body 100 and on the outer wall of the body 100, and the two are connected; a plurality of counterweight cavities 110 are provided at different positions in the body 100, and each counterweight cavity 110 is connected to the water pump 300; the detection component 500 is installed on the outer wall of the body 100, adjacent to the external delivery pipe 400, and extends toward one end of the body 100; the power arm 200 is provided with a plurality of and embedded in different positions of the outer wall of the body 100, and a fan blade 213 is installed at one end of the power arm 200 away from the body 100, which can rotate clockwise or counterclockwise; wherein, the middle part of the power arm 200 can be rotated and adjusted. In this way, after the device is connected to the external water source and the external power supply, the functionality and safety of the device are checked. After the device is checked correctly, it is suspended from the roof to the outer wall of the stairs by the hoisting equipment and the device is started. At this time, the power arm 200 of the device detects the distance between it and the wall by itself. Affected by the hoisting equipment or other factors, the distance between the device and the wall may be greater than or less than the preset working distance. If the actual distance between the device and the wall is less than the preset distance, the fan blades 213 on the power arm 200 will rotate clockwise at high speed to blow air toward the wall, and the reaction force of the rotation of the fan blades 213 will push the device away from the wall and keep it at the preset distance to perform water spraying and detection operations. On the contrary, if the distance between the device and the wall is greater than the preset distance, the fan blades 213 on the power arm 200 will rotate counterclockwise at high speed to blow and stand up in the direction away from the wall, and the reaction force will also be used to push the device toward the wall and keep it at the preset distance to perform water spraying and detection operations. In addition, when the device encounters obstacles such as decorative strips during operation, the back-blowing effect of the fan blades 213 can be used to allow the device to easily cross the obstacles, so as to ensure that the obstacles will not affect the detection work of the device, thereby improving the applicability of the device detection work.

[0021] When the device is affected by wind direction during operation, causing the device to swing and be unable to continue working, the device can automatically inject water or drain water toward the counterweight chamber 110 in the body 100 through the water pump 300 according to the swing amplitude, so as to achieve the purpose of changing the center of gravity of the device. Secondly, by changing the center of gravity to offset the influence of wind direction, not only the stability of the device is improved, but also the safety of the device is improved. In addition, when the device is in normal working state, the center of gravity can be changed to make a certain lateral displacement of the device, so as to achieve the purpose of increasing the watering area and the detection area, thereby improving the working range and working efficiency of the device.

[0022] Optionally, a plurality of hoisting rings 101 are fixed to one end of the body 100. In this way, the hoisting rings 101 can be connected to the steel cables of the hoisting equipment, so that the device can reach any position of the high-rise building for watering and testing, thereby improving the applicability of the device.

[0023] Optionally, a water pipe connection end and a cable connection end are provided at the bottom of the device, and the two are arranged adjacent to each other. In this way, the device can be connected to the cable and the water pipe in real time, and can be moved synchronously through the lifting equipment, thereby solving the working water and working electricity requirements of the device, and effectively improving the endurance of the device.

[0024] Optionally, a plurality of embedding slots 102 are provided on the side wall of the machine body 100 for connecting the power arm 200, and a data connection slot is fixed in the embedding slot 102. In this way, after the power arm 200 is inserted into the embedding slot 102, the end of the power arm 200 facing the machine body 100 is just connected to the data connection slot, thereby achieving the purpose of data communication with the machine body 100. In this way, the machine body 100 can perform real-time detection and real-time control of the operating parameters of each power arm 200, so as to adjust them in time.

[0025] like Figures 4 to 7 As shown, the power arm 200 includes a connection seat 220 and a connection arm 210. One end of the connection seat 220 is embedded in the body 100, and an elastic locking component 221 is provided on the side wall parallel to the embedded end; the connection seat 220 is also provided with an adjustment machine 222 and an adjustment tooth 223, and the adjustment tooth 223 is installed on the power output shaft at both ends of the adjustment machine 222, and the adjustment tooth 223 is meshed with the connection arm 210. In this way, after the connection seat 220 is inserted into the embedding groove 102, its elastic locking component 221 will pop out automatically and protrude out of the side wall of the body 100, thereby achieving the purpose of locking and preventing the power arm 200 from being separated from the body 100, which not only improves the connection stability between the power arm 200 and the body 100, but also improves the safety of the device operation. In addition, the connecting seat 220 can also cooperate with the adjusting gear 223 to swing the connecting arm 210 so as to adjust the center of gravity of the device in cooperation with the counterweight cavity 110.

[0026] Optionally, the elastic locking assembly 221 includes a tenon 2211 and a spring rod 2212, wherein a plurality of tenons 2211 are provided, which are symmetrically installed in the connection seat 220, and one end of the tenon 2211 protrudes out of the side wall of the connection seat 220; the spring rod 2212 is arranged between the tenons 2211 and fixedly connected to the tenons 2211. In this way, the tenon 2211 can be retracted into the connection seat 220 when being squeezed by an external force, so as to avoid obstruction to the connection between the connection seat 220 and the body 100. When the connection seat 220 is installed in place, the tenon 2211 thereof pops out automatically under the elastic action of the spring rod 2212, so that the connection seat 220 is locked in the body 100.

[0027] Optionally, a protrusion 2201 is provided on one side of the outer wall of the connecting seat 220. In this way, the provided protrusion 2201 can ensure that the power arm 200 is embedded in the machine body 100 in the correct direction, thereby avoiding installation errors of the power arm 200.

[0028] Optionally, a groove 2202 and a hinge groove 2203 are provided at one end of the connection seat 220 away from the body 100, and a plurality of jacks 2204 and threading holes 2205 are provided in the groove 2202. In this way, the groove 2202 and the hinge groove 2203 can provide an installation space and a swing offset adjustment space for the connection arm 210, so that the connection arm 210 can be swung and adjusted smoothly and safely. At the same time, the provided jack 2204 provides a communication space for the engagement of the connection arm 210 with the adjustment tooth 223, so that the connection arm 210 and the adjustment tooth 223 can be stably connected. In addition, the threading hole 2205 provides a space for inserting a data connection cable.

[0029] like Figure 6 and Figure 7 As shown, a guard ring 211 is provided at one end of the connecting arm 210, a brushless motor 212 is installed in the guard ring 211, and a fan blade 213 is installed on the power output shaft of the brushless motor 212; a plurality of adjustment synapses 214 adapted to the adjustment teeth 223 are provided at one end of the connecting arm 210 away from the guard ring 211, and the adjustment synapses 214 are embedded in the connecting seat 220 and meshed with the adjustment teeth 223. In this way, the adjustment synapses 214 provided at the end of the connecting arm 210 can be synapsed into the connecting seat 220 through the jack 2204 adapted thereto and meshed with the adjustment teeth 223, so that the connecting arm 210 can be swung and adjusted. At the same time, the guard ring 211 provided can protect the fan blade 213 and the brushless motor 212 through the guard ring 211, so that the fan blade 213 and the brushless motor 212 are not easily damaged by contact with other foreign objects during operation, and the service life of the fan blade 213 and the brushless motor 212 is effectively improved.

[0030] Optionally, symmetrical hinge columns 2101 are provided on the outer wall of the connecting arm 210. In this way, the symmetrically arranged hinge columns 2101 are adapted to the hinge slots 2203, so that the connecting arm 210 can rotate with the hinge columns 2101 and the hinge slots 2203 as the axis.

[0031] like Figure 6 and Figure 7 As shown, a distance sensor 215 is installed in the connecting arm 210 and protrudes toward the outer wall of the connecting arm 210. In this way, the distance between the device and the wall can be detected in real time through the distance sensor 215 provided on each connecting arm 210, and the speed of the brushless motor 212 can be adjusted according to the detected real-time distance, so that the fan blade 213 increases or decreases the speed, thereby changing the wind pressure generated by the fan blade 213, thereby achieving the purpose of controlling the distance between the device and the wall.

[0032] like Figure 8 As shown, the outer wall of the counterweight chamber 110 is provided with a water inlet pipe 111 and a drain pipe 112 connected to the inner wall thereof, and one end of the water inlet pipe 111 is connected to the water inlet end of the water pump 300, while the drain pipe 112 is connected to the water delivery end of the water pump 300. In this way, after the water inlet pipe 111 and the drain pipe 112 installed on the counterweight chamber 110 are connected to the water inlet end and the water delivery end of the water pump 300, a water pump 300 can take care of the watering work while taking care of the water injection and drainage work of the counterweight chamber 110, thus achieving the purpose of one to many. The device does not need to install an additional pump body to inject water and drain water to the counterweight chamber 110, effectively reducing the overall weight of the device, while saving the internal space of the body 100, so that the body 100 can be equipped with more and larger counterweight chambers 110, thereby improving the effective counterweight adjustment effect of the body 100.

[0033] Optionally, the counterweight chamber 110 includes a first chamber 1101, a second chamber 1102, a third chamber 1103, and a fourth chamber 1104, wherein the first chamber 1101 and the second chamber 1102 are installed on one side inside the body 100, and the third chamber 1103 and the fourth chamber 1104 are installed on the other side inside the body 100.

[0034] Optionally, drainage grooves 1105 are provided on the side walls of the third chamber 1103 and the fourth chamber 1104. In this way, when water accumulates due to pipeline damage in the machine body 100, the accumulated water can be quickly collected at the bottom of the machine body 100 and drained through the drainage grooves 1105, thereby preventing the electronic components in the machine body 100 from being damaged by long-term immersion in the accumulated water, and effectively improving the service life of the device.

[0035] like Figure 8As shown, a first electrically controlled valve 1111 is installed in the middle of the water inlet pipe 111; and a second electrically controlled valve 1121 is installed in the middle of the drain pipe 112. In this way, different water inlet pipes 111 and drain pipes 112 can be controlled separately through the first electrically controlled valve 1111 and the second electrically controlled valve 1121. For example, when one of the counterweight chambers 110 needs to be filled with water, only the first electrically controlled valve 1111 on the water inlet pipe 111 connected thereto is opened. At this time, the water pump 300 can supply water to the counterweight chamber 110 with the first electrically controlled valve 1111 opened while supplying water to the water supply assembly. On the contrary, when the counterweight chamber 110 needs to be drained, the first electrically controlled valve 1111 on the water inlet pipe 111 is closed, and the second electrically controlled valve 1121 on the drain pipe 112 is opened, and the water in the counterweight chamber 110 is discharged by the suction force of the water pump 300.

[0036] Optionally, a vent hole is provided on the side wall of the counterweight chamber 110, and is arranged adjacent to the water inlet pipe 111. In this way, the vent hole can ensure that appropriate air can enter or be discharged from the counterweight chamber 110 during the process of filling or draining water, so as to ensure the pressure balance in the counterweight chamber 110. This avoids the inability of the water pump 300 to complete the filling or draining work due to the air in the counterweight chamber 110 being unable to circulate during the working process.

[0037] like Fig. 9 As shown, the external delivery pipe 400 includes a main pipe 401, a connecting pipe 402, and a nozzle 403. A plurality of brackets 404 for connecting to the body 100 are installed on the outer wall of the main pipe 401, and one end of the main pipe 401 is embedded in the body 100 and connected to the water inlet end of the water pump 300; one end of the connecting pipe 402 is connected to the main pipe 401, and the other end is installed with a nozzle 403. In this way, the external delivery pipe 400 is formed by connecting the main pipe 401, the connecting pipe 402 and the nozzle 403 in series. Compared with the integrated structure, this series connection method can select connecting pipes 402 and nozzles 403 of different specifications according to actual operation requirements. Thereby improving the working applicability of the device. At the same time, the main pipe 401 connected to the main body through the bracket 404 is located in the middle of the body 100 and can be used as a handle to provide a force fulcrum for short-distance transportation of the body 100.

[0038] like Fig.10As shown, the detection assembly 500 includes a fixed rod 501, an extension rod 502, a slide rail 503, and a detection host 510. The fixed rod 501 is provided in plurality and is respectively arranged on both sides of the external delivery tube 400. The outer wall of the fixed rod 501 is provided with a plurality of vertical connecting rods for connecting the body 100. The number of the extension rods 502 matches the number of the fixed rods 501, one end of the extension rods 502 is connected to the fixed rod 501, and the other end is connected to the slide rail 503. The detection host 510 is movably connected to the slide rail 503. In this way, the fixed rod 501, the extension rod 502, and the slide rail 503 are also designed in series, and different specifications of the extension rods 502 and the slide rail 503 can be selected according to actual use needs, so as to improve the applicability of the detection assembly 500.

[0039] Optionally, both ends of the slide rail 503 are provided with limit plugs 5031, and one end of the limit plug 5031 is provided with a magnet 5032. In this way, when the detection host 510 moves to one end, it can be blocked by the limit plug 5031, so as to prevent the detection host 510 from excessive displacement and separation from the slide rail 503, so as to ensure that the detection host 510 can stably perform the detection work. At the same time, the magnet 5032 provided on the limit plug 5031 is adapted to the components in the detection host 510. When the detection host 510 moves to one end of the slide rail 503, the magnet 5032 senses the internal components of the detection host 510, so that the detection host 510 stops moving and moves in the opposite direction.

[0040] like Fig.11 As shown, the detection host 510 is composed of a motion platform 511, a detection probe 512, a motion motor 513, a motion wheel 514, and a connection module 515. The motion platform 511 is sleeved and connected with the slide rail 503, and a detection probe 512 is installed on one side of the motion platform 511, and a motion motor 513 and a connection module 515 are installed on the other side facing away from the detection probe 512; wherein, motion wheels 514 are installed on the power output shafts at both ends of the motion motor 513, and the motion wheels 514 protrude to the inner side of the motion platform 511 and mesh with the slide rail 503. In this way, under the cooperation of the motion motor 513 and the motion wheel 514, the motion platform 511 is driven to do a reciprocating motion along the slide rail 503. During the motion of the motion platform 511, the detection probe 512 performs uninterrupted scanning and detection of the wall along the motion trajectory, thereby completing the water seepage detection work of the wall. At the same time, the detection probe 512 is connected to the machine body 100 through the connection module 515 and the data cable, thereby completing the real-time transmission of the detection data.

[0041] Optionally, both ends of the motion platform 511 are embedded with induction components adapted to the magnets 5032. In this way, the magnets 5032 cooperate with the induction components to not only limit the motion platform 511, but also control the motion direction of the motion platform 511.

[0042] like Fig.12 As shown, a sealed cavity 120 is provided in the body 100, and a plurality of control circuit boards 121 are embedded in the sealed cavity 120. In this way, the sealed cavity 120 can effectively protect the control circuit boards 121, reduce the possibility of water flow and water vapor entering the sealed cavity 120, make the control circuit boards 121 less likely to have faults such as short circuits due to moisture, and ensure that the device can operate safely and stably.

[0043] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
