[0002] Urban culverts (also known as underground channels or box culverts) refer to enclosed drainage channels buried underground or covered. They are mainly used for the discharge of urban rainwater and sewage, or as a comprehensive corridor for cables and pipelines. Urban culverts need to be inspected regularly when used for drainage. They are usually inspected by unmanned inspection boats, and the existing unmanned inspection boats are the equipment used for regular inspection of urban culverts.

[0003] Existing unmanned inspection vessels used for inspection inside urban culverts have limitations. During inspection, it is inconvenient to protect the edges of the vessel and increase buoyancy support. This makes the vessel susceptible to damage from impacts, affecting the ease of protection and buoyancy support during inspections in urban culverts. Therefore, this invention proposes an unmanned inspection vessel for urban culverts. Utility Model Content

[0004] The purpose of this utility model is to provide an unmanned surface vessel for inspecting urban culverts, in order to solve the problem mentioned in the background art that it is inconvenient to protect the edges of the unmanned surface vessel and increase buoyancy support when it is in motion, which makes it easy for the unmanned surface vessel to be damaged by impact when inspecting inside the culvert.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an unmanned surface vessel (USV) for inspecting urban culverts, comprising a main body, the main body including a hull, a bottom plate at the bottom of the hull, side plates at the edges of the hull, an electric drive mechanism inside the hull, and drive propellers rotatably mounted on both sides of the hull via the electric drive mechanism. The main body of the USV also includes:

[0006] An anti-collision protection mechanism is provided, and the anti-collision protection mechanism includes an anti-collision protection component disposed at the edge of the side plate, an air intake component is disposed on one side of the upper surface of the anti-collision protection component, and a fixing installation component is disposed at the connection between the edge of the anti-collision and the side plate.

[0008] Preferably, a bracket is fixedly installed at the middle position of the upper surface of the hull, and a front camera and a rear camera are fixedly installed on the top two sides of the bracket, respectively. A front light is provided on both sides of the front surface of the front camera, and two rear lights are provided at the end of the rear camera. A data processing and remote transmission module is fixed to one end of the upper surface of the hull, and the data processing and remote transmission module is electrically connected to the front camera and the rear camera by wires. Two handles are fixed to one end of the upper surface of the hull by mounting bolts.

[0009] Preferably, the anti-collision protection component includes an inflatable airbag disposed on the outer surface of the side plate, and the lower surface of the inflatable airbag matches the surface structure of the bottom plate.

[0010] Preferably, the air intake assembly includes an air inlet disposed at one end of the upper surface of the inflatable airbag, and a sealing cap is threadedly connected to the surface of the air inlet.

[0011] Preferably, the fixed installation assembly includes a fixing piece that closes to the edge of the outer surface of the inflatable airbag, and the upper and lower surfaces of the side plate are provided with an embedding groove that engages with the end of the fixing piece.

After the airbag is filled with air, the unmanned inspection vessel will increase buoyancy by inflating the airbag during its inspection inside urban culverts. When the vessel is touched during inspection, the airbag will directly impact the outer surface of the inflatable airbag for buffer protection. This will cause the unmanned inspection vessel to deform upon impact, reducing the impact and making it less likely to be damaged. This improves the convenience of anti-collision protection and increased buoyancy support for stable navigation of the unmanned inspection vessel during inspections in urban culverts.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: an unmanned surface vessel for inspecting urban culverts, including an inspection unmanned surface vessel body 100, the inspection unmanned surface vessel body 100 including a hull 101, a bottom plate 103 provided at the bottom end of the hull 101, a side plate 104 provided at the edge of the hull 101, an electric drive mechanism provided inside the hull 101, and drive propellers 102 rotatably mounted on both sides of the hull 101 through the electric drive mechanism. The electric drive mechanism includes a motor, a reducer and a power storage power supply. When the motor is running, it drives the reducer to rotate. The rotation of the reducer drives the end gear to mesh with the gear surface connected to the external drive propeller 102 to rotate and drive the drive propeller 102 to drive the inspection unmanned surface vessel body 100 to travel in the urban culvert for inspection.

[0024] A bracket 106 is fixedly installed at the middle of the upper surface of the hull 101. A front-facing camera 109 and a rear-facing camera 108 are fixedly installed on the top two sides of the bracket 106, respectively. Front lights 1091 are provided on both sides of the front surface of the front-facing camera 109, and two rear lights are provided at the end of the rear-facing camera 108. A data processing and remote transmission module 107 is fixed to one end of the upper surface of the hull 101, and the data processing and remote transmission module 107 is electrically connected to the front-facing camera 109 and the rear-facing camera 108 by wires. Two handles 105 are fixed to one end of the upper surface of the hull 101 by mounting bolts. When the inspection unmanned vessel body 100 is in use, it can be placed inside the urban culvert by holding the handles 105, and vice versa for easy removal. The inspection unmanned vessel body 100 is also equipped with:

[0025] The anti-collision protection mechanism includes an anti-collision protection component located at the edge of the side plate 104. An air intake component is provided on one side of the upper surface of the anti-collision protection component, and a fixing installation component is provided at the connection between the edge of the anti-collision component and the side plate 104. The anti-collision protection mechanism can protect the hull 101 of the inspection unmanned vessel 100 from collisions during inspection, while increasing buoyancy and stabilizing support for inspection use.

[0026] In order to facilitate edge collision protection of the hull 101 through the anti-collision protection component, and at the same time increase buoyancy so that the inspection unmanned vessel body 100 can effectively drive and inspect, in this embodiment, preferably, the anti-collision protection component includes an inflatable airbag 1041 disposed on the outer surface of the side plate 104, and the lower surface of the inflatable airbag 1041 matches the surface structure of the bottom plate 103.

[0027] In order to facilitate the intake of air into the inflatable airbag 1041 for collision protection and to increase buoyancy during driving, in this embodiment, preferably, the air intake assembly includes an air inlet 1044 disposed at one end of the upper surface of the inflatable airbag 1041. A sealing cap 1043 is threadedly connected to the surface of the air inlet 1044. The airbag 1041 can be filled with air through the air inlet 1044, and after inflation, the sealing cap 1043 is rotated to seal the air inlet 1044.

[0028] To facilitate the fixed installation of the inflatable airbag 1041 on the edge of the side plate 104 using a fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes a fixing piece 1042 that closes on the outer surface edge of the inflatable airbag 1041. The upper and lower surfaces of the side plate 104 are each provided with an embedding groove 1046 that engages with the end of the fixing piece 1042. Fixing bolts 1045 are provided at both ends of the fixing piece 1042. An internal threaded hole 1047 matching the fixing bolt 1045 is provided inside the embedding groove 1046. After the inflatable airbag 1041 is closed, the fixing piece 1042 closes on the outer surface of the inflatable airbag 1041, and the end of the fixing piece 1042 closes inside the embedding groove 1046. The fixing bolt 1045 is rotated and embedded into the internal threaded hole 1047 for fixed installation, facilitating the fixed installation of the inflatable airbag 1041.

[0029] The guide mechanism includes guide components at both ends of the lower surface of the side plate 104. Rotation and fixing components are provided at the connection between the two sides of the guide components and the surface of the side plate 104. During inspection, dirt in front of the culvert can be guided into both sides by the guide mechanism, which facilitates driving, is not easily obstructed, and enables effective inspection operations.

[0030] In order to facilitate the guidance of the inspection unmanned vessel body 100 to the sides before it moves, so as to prevent dirt from getting tangled on the surface of the drive propeller 102, in this embodiment, preferably, the guidance component includes a diamond-shaped plate 1031 set at both ends of the lower surface of the base plate 103, and a connecting plate 1032 is integrally provided at both ends of the diamond-shaped plate 1031.

[0031] In order to facilitate the fixed installation of the rhombus plate 1031 on both ends of the lower surface of the base plate 103 by means of a rotating fixing assembly, in this embodiment, preferably, the rotating fixing assembly includes a fixing bolt 1033 threaded to the surface of the connecting plate 1032, and an internal threaded hole 1034 corresponding to the fixing bolt 1033 is provided at the end of the lower surface of the base plate 103. After the rhombus plate 1031 is closed and installed, the rotating fixing bolt 1033 is inserted into the internal threaded hole 1034 to fix the rhombus plate 1031, which is convenient for fixing and use.

[0032] The working principle and usage process of this utility model are as follows: When using this type of unmanned inspection vessel for urban culverts, the main body 100 of the inspection vessel is placed directly inside the urban culvert. The drive propeller 102 drives the main body 100 of the inspection vessel to move. When moving inside the urban culvert, the rear camera 108 and the front camera 109 are powered on. The front light 1091 illuminates the front surface, and the rear light illuminates the rear surface, so that the front camera 109 and the rear camera 108 can clearly illuminate and capture images of both the front and rear surfaces. After image processing, the data is fed back to the data processing and remote transmission module 107 and then transmitted to the outside for monitoring. This makes it convenient to use the inspection vessel 100 for inspection inside the urban culvert.

[0033] Then, when the unmanned surface vessel 100 is under inspection, the inflatable airbag 1041 closes at the edge of the side plate 104, and the fixing plate 1042 closes again. The end of the fixing plate 1042 is inserted into the insertion groove 1046, and the fixing bolt 1045 is rotated into the internal threaded hole 1047 to fix the fixing plate 1042. Therefore, after the fixing plate 1042 is fixedly installed, the inflatable airbag 1041 is closed and limited. The inflatable airbag 1041 is inflated through the air inlet 1044, and the sealing cover 1043 is rotated to seal it. After being fully inflated, the outer surface of the inflatable airbag 1041 is sealed. The inflatable airbag 1041 reinforces the unmanned inspection vessel 100 by making full contact with the inner surface of the fixing plate 1042. Therefore, when the unmanned inspection vessel 100 is inspected inside the urban culvert, the inflatable airbag 1041 increases the buoyancy of the unmanned inspection vessel 100. When it is touched during inspection, it directly touches the outer surface of the inflatable airbag 1041 for buffer protection. This allows the unmanned inspection vessel 100 to deform and reduce the impact when it is hit, making it less likely to be damaged by impact. This improves the convenience of the unmanned inspection vessel 100 in protecting the hull 101 from impact and increasing buoyancy to support stable driving when inspecting urban culverts.

[0034] Finally, before using the inspection unmanned vessel body 100, the diamond plate 1031 and the connecting plate 1032 are closed at the mounting position on the lower surface of the side plate 104. The diamond plate 1031 is fixed by rotating the fixing bolt 1033 into the internal threaded hole 1034. After the diamond plate 1031 is fixed, when the inspection unmanned vessel body 100 is inspecting inside the culvert, the lower surface of the side plate 104 is in contact with water, and the diamond plate 1031 is flush with the horizontal contact. When dirt appears on the surface of the water before driving, the dirt can be guided by the end of the diamond plate 1031 to both sides of the diamond plate 1031 until it is driven out to the outside. This makes it less likely for dirt to get tangled on the surface of the drive propeller 102, facilitates the guidance and removal of dirt, and improves the convenience of the inspection unmanned vessel body 100 in guiding and removing dirt from the bottom of the side plate 104 when inspecting urban culverts.
