Description

Technical Field

[0001] The present invention relates to the technical field of anti-seepage quality monitoring for hydraulic buildings, and particularly to an anti-seepage quality monitoring device for hydraulic buildings. Background Art

[0002] As the core technology of hydraulic engineering, the anti-seepage construction technology is highly professional and covers many construction elements such as geological exploration, material selection, and process application. By scientifically applying the anti-seepage technology, problems such as leakage and piping during the operation of hydraulic engineering can be effectively prevented, ensuring the long-term stable operation of the project.

[0003] For key hydraulic facilities such as hydraulic dams and anti-seepage walls, the detection of anti-seepage performance after completion is particularly important. In engineering practice, simulated water injection tests are often used. By introducing water flow into the building and observing the seepage situation on the back of the structure, the anti-seepage effect can be visually evaluated. At the same time, with the help of advanced equipment such as concrete ultrasonic detectors, non-destructive testing of the internal structure of the building main body is carried out to accurately identify quality defects such as honeycombing and cavities, building a solid defense line for the safe operation of hydraulic engineering.

[0004] Among the existing detection devices, for example, Chinese Patent: CN116879135A (Publication Date: October 13, 2023) discloses an anti-seepage quality monitoring device for hydraulic engineering buildings, which includes a monitoring body, a connecting wire, and a monitoring probe. The monitoring probe is connected to the monitoring body through the connecting wire. The monitoring body monitors the anti-seepage of the building main body through the monitoring probe and displays the monitoring results on the monitoring body. The monitoring body is installed on a fixed body, and the fixed body is installed on a moving slide rail installed on the upper side of the top of the building main body. Through the movement of the moving bracket, this invention can comprehensively detect the detection positions presenting a grid on the side wall of the building main body. During this process, the automation and high efficiency of the detection of the building main body are realized, the labor input is reduced, and a large area and multiple positions of detection targets can be comprehensively detected with fewer detection devices, saving the time required for the overall anti-seepage quality monitoring of the building main body and improving the monitoring efficiency.

[0005] However, during the detection process of this invention, it is necessary to control the movement of the monitoring probe on the building main body through the connecting wire. When the position detected by the monitoring probe is far away, the connecting wire needs a longer distance, which will cause the monitoring probe to shake or swing during the movement. Moreover, it takes a long time to control the movement of the monitoring probe to the specified position through the elongation or locking of the connecting wire, reducing the monitoring effect and monitoring efficiency. Summary of the Invention

[0006] The technical object to be achieved by the present invention is as follows: When the existing monitoring device is in the monitoring process, when the position detected by the monitoring probe is relatively far, a longer connecting line is required, resulting in the monitoring probe shaking or swinging during the movement process, and it takes a longer time during the movement process, reducing the monitoring effect and monitoring efficiency; during the monitoring process of the monitoring device, it is not necessary to connect and control through a connecting line, the monitoring probe will not shake or swing, and it can freely move to the designated position for monitoring, saving a lot of time and greatly improving the monitoring effect and monitoring efficiency.

Detailed implementation manners

[0037] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0038] As shown Figures 1 to 13 in the figure, a water conservancy building seepage prevention quality monitoring device includes: a housing 1, a connecting frame 2, a floating airbag 3, a camera 4, a ring 5, a brush block 6, a detection element 7, a driving component 8 and an adjusting component 9; A connecting frame 2 is installed on the top of the housing 1, a floating airbag 3 is installed on the connecting frame 2, a camera 4 is installed on the top of the housing 1, a ring 5 is installed on one end face of the housing 1, a brush block 6 is installed on one end face of the housing 1, and a detection element 7 is installed on one end face of the housing 1, and the ring 5, the brush block 6 and the detection element 7 are located on the same surface. A driving component 8 and an adjusting component 9 are respectively installed inside the housing 1;

[0039] Through the combined action of the adjusting component 9 and the floating airbag 3, the monitoring device is driven to lift and lower, and the driving component 8 is used to drive the brush block 6 to clean the detection area, so that the detection element 7 can detect different positions of the building wall.

[0040] As the core carrier of the entire device, the housing 1 is made of a high-strength and corrosion-resistant alloy material, which can resist the erosion of complex underwater environments and provide reliable protection for internal precision components. The connecting frame 2 installed on the top of the housing 1 is not only the installation foundation of the floating airbag 3, but also has a stable mechanical connection structure to ensure the close connection between the floating airbag 3 and the housing 1.

[0041] The floating airbag 3 is made of a polymer flexible material and has good airtightness and water pressure resistance. The initial buoyancy of the floating airbag 3 is fixed and can carry the entire device to float upward to the water surface. By controlling the water volume inside the water tank 14 through the adjusting component 9, the overall weight of the device can be controlled, so that the device can move up and down freely in the water and flexibly detect different positions.

[0042] The high-definition camera 4 installed on the top of the housing 1 is equipped with a wide-angle lens and a waterproof protective cover, which can capture the underwater environment picture around the device in real time and transmit the image information to the ground control terminal, facilitating the operator to intuitively master the operation state and detection position of the device.

[0043] At the detection end of the housing 1, the ring 5, the brush block 6 and the detection element 7 are distributed on the same end face. The ring 5 is wrapped with an elastic buffer material, which plays a buffering and positioning role when the device approaches the building wall, ensuring the accurate contact between the brush block 6 and the detection element 7 and the wall surface. The brush block 6 consists of high-strength wear-resistant bristles 61 and a rotatable connecting shaft, and is connected to the transmission module 87 in the driving component 8. The driving component 8 includes components such as a driving motor 81, a gear transmission system and a transmission shaft 85. The driving motor 81 transmits power to the transmission shaft 85 through the speed change and transmission of the gear set, and then drives the brush block 6 to rotate at a high speed to efficiently clean the wall surface of the detection area, removing sundries such as sediment and algae attached to the surface, and ensuring that the detection element 7 can obtain accurate detection data.

[0044] The detection element 7 adopts a multi-frequency ultrasonic sensor array, which can emit ultrasonic waves of different frequencies to penetrate the building wall. According to the time, intensity and frequency changes of the reflected echo, it can accurately analyze the key anti-seepage quality indicators such as the concrete density, crack distribution and water seepage channel inside the wall. Through the precise control of the buoyancy of the device by the adjustment component 9 and the driving of the brush block 6 and the device movement by the driving component 8, the detection element 7 can comprehensively and carefully detect different depths and positions of the building wall.

[0045] As Figure 5 and Figure 6 shown, the driving component 8 includes a driving motor 81, a rotating shaft 82, a first gear 83, a support seat 84, a transmission shaft 85, a second gear 86, a transmission module 87, a rotating shaft 88 and a bevel gear shaft 89; the driving motor 81 is horizontally installed at the bottom of the housing 1, the rotating shaft 82 is installed on the driving motor 81, the free end of the rotating shaft 82 passes through the housing 1, and a propeller 821 is arranged at the free end, a first gear 83 is arranged on the rotating shaft 82, a plurality of support seats 84 are installed at the bottom of the housing 1, a transmission shaft 85 is installed on the plurality of support seats 84, the axis of the transmission shaft 85 is parallel to the axis of the rotating shaft 82, a second gear 86 is installed at one end of the transmission shaft 85, the second gear 86 meshes with the first gear 83, a transmission module 87 is installed at the other end of the transmission shaft 85, a rotating shaft 88 is installed on the transmission module 87, a first bevel gear 881 is arranged on the rotating shaft 88, the bevel gear shaft 89 is installed on the inner wall of the housing 1, and the shaft end of the bevel gear shaft 89 penetrates the housing 1 and is connected to the brush block 6, and the tooth end of the bevel gear shaft 89 meshes with the first bevel gear 881.

[0046] As the power transmission core of the entire monitoring device, the driving component 8 adopts a modular integrated design and is composed of precision components such as a driving motor 81, a rotating shaft 82, a first gear 83, a support seat 84, a transmission shaft 85, a second gear 86, a transmission module 87, a rotating shaft 88 and a bevel gear shaft 89. Each component operates in coordination through rigorous mechanical transmission.

[0047] The driving motor 81 is a high-torque, waterproof DC servo motor, which is horizontally installed at the bottom of the housing 1 through a special shock-absorbing base. It can effectively isolate the vibration generated by the motor operation, prevent interfering with the work of the detection element 7, and provide a stable support. The propeller 821 can generate a strong thrust when rotating, driving the device to move flexibly in the water.

[0048] To ensure the smooth operation of the transmission shaft 85, multiple high-strength support seats 84 are symmetrically installed at the bottom of the housing 1. Self-lubricating bearings are embedded inside the support seats 84, which can effectively reduce the frictional resistance when the transmission shaft 85 rotates. The transmission shaft 85 is arranged in parallel with the rotating shaft 82, and the coaxiality is accurately calibrated through the bearing seat. The second gear 86 installed at one end thereof meshes with the first gear 83, which can achieve a reasonable conversion of speed and torque and ensure the high efficiency of power transmission.

[0049] The other end of the transmission shaft 85 is connected to the transmission module 87, which has a structure of a closed box 871, and a complex speed change and commutation mechanism is integrated inside. The bevel gear shaft 89 is installed on the inner wall of the housing 1 through a special bearing seat, and its axis is perpendicular to and intersects with the rotating shaft 88. The tooth end at one end of the bevel gear shaft 89 forms a bevel gear meshing pair with the first bevel gear 881, and the other end penetrates through the side wall of the housing 1 and is rotationally sealed and rigidly connected to the external brush block 6. A double-sealing structure is adopted, with wear-resistant ceramic rings and fluororubber sealing rings built in, which can not only ensure the free rotation of the bevel gear shaft 89 but also effectively prevent water from seeping into the device.

[0050] As Figures 7 to 9 shown, the transmission module 87 includes a box 871, a fixing ring 872, a second bevel gear 873, a moving rod 874, a fixing cylinder 875, and a sliding block 876; the box 871 is installed inside the housing 1, the fixing ring 872 is installed on the inner wall of the box 871, the second bevel gear 873 is rotatably installed on the fixing ring 872, the moving rod 874 is movably installed on the box 871, and one end of the moving rod 874 is located inside the box 871 and the other end penetrates through the housing 1. The moving rod 874 and the fixing ring 872 are on the same axis. A fixing cylinder 875 is provided at one end of the moving rod 874 close to the second bevel gear 873, and a sliding block 876 is rotatably installed on the fixing cylinder 875, and the sliding block 876 and the transmission shaft 85 are in sliding fit with each other.

[0051] The transmission module 87 is composed of precision components such as a box 871, a fixing ring 872, a second bevel gear 873, a moving rod 874, a fixing cylinder 875, and a sliding block 876. Each component realizes the precise transmission and control of power through a clever mechanical linkage.

[0052] The box 871 has excellent waterproof and corrosion-resistant properties and can resist the erosion of complex underwater environments. The box 871 is rigidly connected to the installation bracket 12 preset inside the housing 1 through the bolt holes around it, and a rubber gasket is added at the connection to ensure the overall sealing performance.

[0053] The fixed ring 872 provides stable rotational support for the second bevel gear 873. The moving rod 874 is movably installed through a guiding hole opened at the top of the box body 871, and a self-lubricating copper sleeve is embedded in the guiding hole, which can not only ensure the linear movement of the moving rod 874 but also reduce the frictional resistance. One end of the moving rod 874 extends outside the box body 871 and is connected to the mechanical trigger mechanism at the front end of the device, while the other end is located inside the box body 871 and is used to control power transmission.

[0054] The fixed cylinder 875 is vertically welded to the inner end of the moving rod 874, and its axis is strictly coaxial with the moving rod 874. The fixed cylinder 875 is rotatably connected to the sliding block 876, enabling the sliding block 876 to rotate around its own axis and axially move along with the moving rod 874 under the constraint of the fixed cylinder 875.

[0055] The sliding block 876 is conical, and its conical surface matches the conical surface of the second bevel gear 873. The surface is subjected to a special anti-slip treatment to increase the frictional force when the two come into contact. A spline groove is machined in the inner hole of the sliding block 876, forming a sliding fit with the rectangular groove 853 on the transmission shaft 85. This design allows the sliding block 876 to freely slide axially on the transmission shaft 85 while being able to transmit torque. When the moving rod 874 axially moves under the action of an external mechanical force, the sliding block 876 moves accordingly, and its conical surface contacts and presses against the second bevel gear 873, thereby transmitting the rotational power of the transmission shaft 85 to the second bevel gear 873; when the external force disappears, the sliding block 876 separates from the second bevel gear 873 under the action of the first spring 852, cutting off the power transmission and realizing the start-stop control of the brush block 6.

[0056] As Figure 8 shown, a third bevel gear 882 is provided at one end of the rotating shaft 88 away from the first bevel gear 881, and the third bevel gear 882 meshes with the second bevel gear 873.

[0057] In the entire transmission system, the third bevel gear 882 serves as a key reversing transmission component, converting the horizontally rotating power transmitted by the second bevel gear 873 into vertically rotating power. When the second bevel gear 873 rotates at high speed driven by the transmission shaft 85, through the mutual meshing between the tooth surfaces, it drives the third bevel gear 882 to rotate synchronously, and then drives the rotating shaft 88 to rotate. The rotation of the rotating shaft 88 in turn drives the first bevel gear 881, the bevel gear shaft 89, and the brush block 6, finally realizing the cleaning operation of the brush block 6 on the building wall.

[0058] As Figures 7 to 9 shown, the sliding block 876 is of a conical structure, the middle part of the second bevel gear 873 is of a conical groove structure, and the conical sliding block 876 cooperates with the conical groove structure of the second bevel gear 873.

[0059] The sliding block 876 and the second bevel gear 873 adopt a tapered surface mating structure. The sliding block 876 is designed as a truncated cone as a whole, and the tapered groove structure in the middle of the second bevel gear 873 is the key carrier for precise mating with the sliding block 876. When the monitoring device approaches the building wall surface, the front ring 5 is subjected to the reaction force of the wall surface, pushing the moving rod 874 to move axially into the box body 871, driving the sliding block 876 to gradually embed into the tapered groove of the second bevel gear 873. At the moment of contact between the two, a self-locking force is generated through the tapered surface wedge effect. As the embedding depth increases, the contact area increases exponentially, and the frictional torque rises rapidly, thereby achieving power transmission.

[0060] This precise tapered mating structure, combined with the contact pressure and rotational speed data monitored by the sensor in real time, enables the control system to achieve a millisecond-level response for power engagement, allowing the monitoring device to quickly switch between the cleaning and detection modes, significantly improving the operation efficiency.

[0061] As Figure 10 shown, at one end of the transmission shaft 85 far from the second gear 86, there is a disc 851. On the disc 851, there is a first spring 852. The free end of the first spring 852 is connected to the sliding block 876. A plurality of rectangular grooves 853 are arranged in a circular array centered on the axis of the transmission shaft 85, and the plurality of rectangular grooves 853 cooperate with the sliding block 876.

[0062] As a key power transmission component in the drive assembly 8, the transmission shaft 85 is fixedly installed with a high-strength alloy disc 851 at one end far from the second gear 86, ensuring that there is no relative displacement under high-speed rotation conditions. On the side of the disc 851 facing the sliding block 876, there is a first spring 852, which can provide a stable reset force for the sliding block 876 and effectively buffer the impact load during the power engagement process. The two ends of the first spring 852 are rigidly connected to the disc 851 and the sliding block 876 respectively through special card slots to ensure the reliability of the connection.

[0063] At the position of the bottom of the sliding block 876 corresponding to the groove of the transmission shaft 85, there is a rectangular convex block that matches it. When the sliding block 876 moves axially along the transmission shaft 85 under the push of the moving rod 874, the convex block meshes precisely with the rectangular groove 853, which can not only limit the circumferential rotation of the sliding block 876 to ensure its synchronous rotation with the transmission shaft 85, but also allow it to slide axially flexibly under the action of the first spring 852, ensuring the reliability and stability of the entire power transmission. When the power needs to be cut off, the first spring 852 releases its elastic potential energy, pushing the sliding block 876 to quickly reset and realizing the rapid separation of power.

[0064] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 11As shown in the figure, an arc-shaped baffle 11 is provided on one end face of the outer shell 1. The arc-shaped baffle 11 is located above the brush block 6. A plurality of bristles 61 are provided on the brush block 6. A water tank 14 is provided at the bottom of the outer shell 1. A water inlet 13 is opened at the bottom of the water tank 14. A plurality of brackets 12 are provided at the bottom of the water tank 14.

[0065] The arc-shaped baffle 11 is made of a transparent material and has extremely strong impact resistance. It can effectively resist the impact of high-speed underwater water flow and the collision of floating objects. When the brush block 6 cleans the building wall surface, various impurities attached to the wall surface will be scattered, and the arc-shaped baffle 11 can prevent the scattered microorganisms, impurities, etc. from floating upward and blocking the camera 4 at the top. The surface of the baffle is coated with an anti-fouling coating, which can prevent the attachment of algae and microorganisms, facilitating the camera 4 on the outer shell 1 to observe the working state of the brush block 6 in real time.

[0066] Multiple groups of replaceable bristles 61 are embedded inside the brush block 6. The bristles 61 have extremely high wear resistance and flexibility, can penetrate into the fine gaps of the wall surface to remove dirt, and can effectively remove stubborn water scale and cement residues.

[0067] The water tank 14 installed at the bottom of the outer shell 1 has excellent corrosion resistance to prevent water pollution. A filter screen is installed at the water inlet 13, which can effectively intercept large particulate impurities in the water and protect internal components such as the water pump 91. The brackets 12 are used to ensure that the device remains stable during the settlement process and can contact the ground smoothly.

[0068] As Figures 4 to 6 shown, the adjustment component 9 includes a water pump 91, a water inlet pipe 92 and a water outlet pipe 93. The water pump 91 is installed at the bottom of the outer shell 1. The water inlet pipe 92 is installed on the water pump 91. The water inlet pipe 92 passes through the bottom of the outer shell 1 and is connected to the water inlet 13 in the water tank 14. The water outlet pipe 93 is installed on the water pump 91. The water outlet pipe 93 passes through the bottom of the outer shell 1 and communicates with the water tank 14.

[0069] The water inlet pipe 92 has excellent corrosion resistance and flexibility. One end of the water inlet pipe 92 is connected to the water inlet 13 of the water pump 91 through a quick-insert threaded joint, and the other end passes through the waterproof hole reserved at the bottom of the outer shell 1 and is accurately docked with the water inlet 13 at the bottom of the water tank 14. A stainless steel filter screen is installed at the water inlet 13, which can effectively intercept impurities such as sand and water plants in the water and protect the impeller of the water pump 91 from damage.

[0070] The water outlet pipe 93 is connected to the water outlet of the water pump 91 through a flange. The water outlet pipe 93 passes through the bottom of the outer shell 1 and extends into the water tank 14. Through the precise cooperation of the water pump 91, the water inlet pipe 92 and the water outlet pipe 93, the adjustment component 9 can quickly fill or drain the water tank 14 within 10 seconds according to the detection requirements, so that the device can achieve precise control of the diving depth and suspension state.

[0071] As Figure 1 、Figure 2 , Figure 3 , Figure 4 , Figure 12 and Figure 13 As shown in Figure 2 , Figure 3 , Figure 4 , Figure 12 and Figure 13 , the circular ring 5 is connected to the outer shell 1 through two cylinders 51. Connecting rods 52 are respectively arranged on the two cylinders 51. One end of each of the two connecting rods 52 is connected to the circular ring 5, and the other end is provided with a retaining piece 53. The two retaining pieces 53 are respectively located inside the cylinders 51. Second springs 54 are respectively arranged inside the two cylinders 51. One retaining piece 53 is connected to one end of a moving rod 874 passing through the outer shell 1.

[0072] At the front end of the underwater building wall detection device, the circular ring 5, as a key component in direct contact with the wall, can ensure the stability and reliability of the detection process. The circular ring 5 is connected to the outer shell 1 through two cylinders 51 that are parallel and symmetrically distributed to each other. This double-support structure can evenly disperse the thrust and pressure generated during the operation of the device, avoiding structural damage caused by excessive local stress.

[0073] When the device approaches the wall, the thrust generated by the propeller 821 is transmitted to the connecting rod 52 through the circular ring 5, thereby pushing the retaining piece 53 to compress the second spring 54, enabling the circular ring 5 to closely fit the wall. When the detection task is completed and the thrust of the propeller 821 weakens, the second spring 54 will, relying on its own elastic potential energy, push the retaining piece 53 and the connecting rod 52 to reset, causing the circular ring 5 to return to its initial position.

[0074] Among the two retaining pieces 53, one is connected to one end of a moving rod 874 passing through the outer shell 1. The other end of this moving rod 874 is connected to the transmission module 87 inside the device. Through its displacement change, power is transmitted, causing the brush block 6 to rotate and clean the building wall.

[0075] As Figure 5 and Figure 6 shown, a sealing box 15 is arranged inside the outer shell 1. A battery 16 is arranged inside the sealing box 15. A plurality of supports 17 are arranged on the battery 16. A circuit control board 18 is arranged on the plurality of supports 17. The drive motor 81, the water pump 91 and the detection element 7 are respectively electrically connected to the circuit control board 18.

[0076] The sealing box 15 can effectively resist the erosion of the underwater high pressure and humid environment, providing a safe and stable working space for the internal precision electronic components. The battery 16 adopts a modular design, featuring high capacity and long endurance, and can meet the power consumption requirements of the device for long-term underwater operation.

[0077] Above the support 17, the circuit control board 18 is erected flat and stably, integrating an advanced microprocessor and complex control circuits. The circuit control board 18 is electrically connected to the drive motor 81, the water pump 91, and the detection element 7 through high-temperature resistant and waterproof shielding cables. Among them, the speed regulation of the drive motor 81, the start and stop control of the water pump 91, and the signal acquisition and processing of the detection element 7 are all precisely regulated by the circuit control board 18 according to the preset program and real-time feedback data. When the device receives a diving instruction, the circuit control board 18 will immediately send a start signal to the water pump 91; in the detection process, it can quickly process the ultrasonic data transmitted back by the detection element 7 and convert it into an intuitive detection report to ensure the efficient and accurate operation of the entire detection process.

[0078] In the working process of the present invention, first, the entire detection device needs to be placed in water, and the entire device is suspended on the water surface through the floating airbag 3 on the device. When detecting a building wall, the position to be detected needs to be determined. When the detected position is below the water surface, at this time, the circuit control board 18 will control the water pump 91 to start, and draw the external water into the water inlet pipe 92 through the water inlet 13, and flow through the water pump 91 to the water outlet pipe 93, and then flow out from the water outlet pipe 93 and enter the inside of the water tank 14. As the water flows into the water tank 14, the weight of the entire device will increase, causing the device to slowly sink downward.

[0079] When the device descends to a certain height, the circuit control board 18 will control the drive motor 81 to drive. The rotation of the drive motor 81 will drive the rotation shaft 82 to rotate, and the rotation shaft 82 will drive the propeller 821 to rotate, and drive the entire device to move forward. At the same time, the camera 4 on the outer shell 1 observes the situation ahead in real time. During the rotation of the rotation shaft 82, the first gear 83 will be driven to rotate. Since the first gear 83 meshes with the second gear 86, the second gear 86 will be driven to rotate together, driving the entire transmission shaft 85 to rotate through the second gear 86, and the transmission shaft 85 will drive the disc 851 and the slider 876 inside the transmission module 87 to rotate together.

[0080] When the device reaches the building wall surface, the circuit control board 18 will control the drive motor 81 to increase the power, causing the device to move forward. The ring 5 will contact the wall surface. As the propeller 821 rotates, a large thrust will be generated, causing the connecting rod 52 on the ring 5 to move into the cylinder 51 and drive the baffle 53 to move, and the baffle 53 will compress the second spring 54, thereby causing the entire device to move forward, making the bristles 61 on the brush block 6 contact the wall surface.

[0081] When the connecting rod 52 drives the baffle 53 to move, inside the cylinder 51 of the moving rod 874, the baffle 53 will also drive the inside of the housing 1 of the moving rod 874 to move, causing the moving rod 874 to drive the fixed cylinder 875 and the sliding block 876 to move forward on the transmission shaft 85. The sliding block 876 compresses the first spring 852, and the conical surface of the sliding block 876 will come into contact with the conical surface of the second bevel gear 873 and generate a large frictional force, transmitting the rotational power of the transmission shaft 85 to the second bevel gear 873. Since the second bevel gear 873 meshes with the third bevel gear 882, it will drive the third bevel gear 882 to rotate. The third bevel gear 882 will drive the rotating shaft 88 to rotate, and the rotating shaft 88 drives the first bevel gear 881 to rotate. Similarly, since the first bevel gear 881 meshes with the bevel gear end on the bevel gear shaft 89, it will drive the bevel gear shaft 89 to rotate, and drive the brush block 6 outside the housing 1 to rotate through the bevel gear shaft 89. During the rotation of the brush block 6, the wall to be detected is cleaned.

[0082] After the wall cleaning is completed, the circuit control board 18 will control the driving motor 81 to reduce the rotation speed, causing the thrust of the propeller 821 to decrease. At this time, the second spring 54 inside the cylinder 51 will push the baffle 53 and the connecting rod 52 to reset. Similarly, the first spring 852 on the transmission shaft 85 will also push the sliding block 876 to slide on the transmission shaft 85, causing the sliding block 876 to disengage from the second bevel gear 873, thereby cutting off the power transmission and causing the brush block 6 to stop rotating. The brush block 6 will be perpendicular downward due to its own gravity. The detection element 7 on the housing 1 will emit ultrasonic waves to penetrate the building main body and detect the internal concrete structure under the impact of water flow according to the reflection, thereby obtaining detection data.

[0083] After the detection at this position is completed, the water volume inside the water tank 14 can be controlled by the water pump 91 on the adjustment assembly 9, thereby controlling the weight of this device, enabling the entire device to dive to different positions, and detecting different positions of the building wall according to the above working process to obtain water penetration data.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
