Description

Technical Field

[0001] This utility model relates to the field of hydrological survey equipment, and more specifically, to an amphibious vehicle for hydrological monitoring. Background Technology

[0002] Current water surveying equipment mainly consists of boats and vessels, which carry the equipment to move in the water and detect data such as the shape of the seabed. However, boats and vessels face significant geographical obstacles, making it difficult to conduct surveys in complex terrains such as multiple regions and waterways. To overcome these problems, the current approach is to combine them with drones. For example, patent CN221623982U discloses a swing platform for drones, which provides a floating structure for drones to enable them to navigate on the water surface and conduct more accurate surveys.

[0003] Although the platform and drones are designed to work together, there is still room for improvement. For example, the swing platform is a twin-hulled floating platform and lacks an intermediate float to reduce the resistance of instruments traveling on the water. Hydrological surveys require the use of various survey instruments, but the current method does not provide instructions on the electrical connections between the survey instruments, sensors, drones, and other electrical components. In particular, there is a lack of protection for the wiring connections. During survey navigation or drone start-up and shutdown, the water may be disturbed, causing water to get into the wiring connections and short-circuit, resulting in equipment damage. This needs to be improved. Utility Model Content

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a preferred embodiment of this utility model, the floating platform includes a first floating platform and two oppositely arranged second floating platforms; the first floating platform is installed in the middle of the bottom surface of the support frame; the two second floating platforms are respectively installed on both sides of the bottom surface of the support frame and are symmetrically arranged about the center of the first floating platform; both the first floating platform and the second floating platform are boat-shaped structures that are narrowed at one end, and both ends of the second floating platform extend beyond the outer side of the support frame.

[0008] In a preferred embodiment of this invention, the bottom end of the second pontoon is provided with an outwardly protruding extension plate, and a marine propeller is installed on the bottom surface of the extension plate.

[0009] In a preferred embodiment of this invention, the first bracket is fixedly mounted between the end side walls of the two second floating platforms by bolts, and its top surface is arched upwards at least 10cm higher than the top surface of the support frame; the junction box is mounted on the top surface of the first bracket by bolts, and its two ends extend towards the second floating platforms; multiple wire holes are provided on the side walls of the junction box, and a wire tube is fixedly mounted on the outside of the wire holes. The outer wall of the wire tube is threaded for installing a wire cover or a sealing cover. The wire cover is provided with a through hole for threading wires; a ring-shaped wire plug is installed inside the wire tube.

[0010] In a preferred embodiment of this invention, the sidewall of the conduit is provided with multiple slits extending along the axial direction, the length of the slits is not less than half the length of the conduit, and the ends of the slits extend to the port of the conduit; the multiple slits are arranged in a circumferential array around the axis of the conduit; the length of the through plug is adapted to the length of the conduit; the outer wall of the through plug is a frustoconical structure, and the diameter of the smaller end is adapted to the inner diameter of the conduit.

[0011] In a preferred embodiment of this invention, a guide structure is installed on the first bracket; the guide structure includes two opposing second brackets, which are bolted to the first bracket; three rollers are rotatably mounted between the two second brackets, extending along the length of the junction box; one roller is located below the crossbeam of the first bracket and corresponds to the center line of the junction box; the other two rollers are located on both sides of the junction box and are higher than the top surface of the first bracket.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model provides a hydrological monitoring amphibious vehicle, including a support frame for carrying drones, a floating platform installed at the bottom of the support frame, the floating platform including three floating structures, and an additional boat-shaped floating body under the instrument mounting frame, which serves to protect the instruments, reduce water surface resistance, and increase buoyancy and stability.

[0014] The support frame has multiple holes for installing hydrological survey instruments. Survey instruments can be added as needed, allowing the whole structure to float on the water surface and conduct surveys of the water body and bottom by navigation.

[0015] The support frame is equipped with an upward-arching first bracket, on which a junction box is mounted. All wires of the electrical components converge at the junction box, which is sealed and extends into the interior through the side wall of the junction box for connection. This design ensures that the wires converge at the junction box for wiring and conduction, effectively protecting the wiring points. Furthermore, the junction box is mounted on the first bracket at a relatively high position, increasing the distance between it and the water surface and effectively preventing water from causing short circuits at the wiring points, thus maintaining stable operation.

Detailed Implementation

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 5As shown in the figure, a specific embodiment of this utility model discloses an amphibious vehicle for hydrological monitoring, including a support frame 200 for carrying a drone 100, and a floating platform installed at the bottom of the support frame; the support frame 200 is provided with a plurality of holes 210 for installing hydrological survey instruments; a first bracket 300 arching upwards is installed on the support frame 200, and a junction box 400 is installed on the first bracket 300; the wires of all electrical components are gathered at the junction box, and the sealing penetrates the side wall of the junction box and extends into the interior, where they are connected.

[0026] The above-mentioned hydrological monitoring amphibious vehicle floats on the water surface via a floating platform and conducts surveys of the water body and seabed by navigating on the water surface. The support frame is equipped with multiple holes for installing hydrological survey instruments, and underwater survey instruments such as ADCP, multibeam sonar, etc. can be added as needed to improve applicability and expand the scope of application.

[0027] The junction box can confine the wires to its interior for wiring and conduction, effectively protecting the wiring parts. Furthermore, the junction box is installed on the first bracket, which is in a relatively high position, increasing the distance between it and the water surface, effectively preventing water from getting into the wiring parts and causing short circuits, thus maintaining stable operation.

[0028] Furthermore, such as Figures 1 to 3 As shown, the floating platform includes a first floating platform 510 and two oppositely arranged second floating platforms 520. The first floating platform 510 is installed in the middle of the bottom surface of the support frame 200. The two second floating platforms 520 are respectively installed on both sides of the bottom surface of the support frame 200, symmetrically arranged about the center of the first floating platform 510. Both the first and second floating platforms are boat-shaped structures that taper at one end, and both ends of the second floating platforms extend beyond the outer side of the support frame. By using the two longer second floating platforms as the main support parts, and the first floating platform in the middle providing auxiliary support, the overall buoyancy can be increased. At the same time, it can block and divert the water waves that impact the middle of the frame or equipment instruments, thus protecting the instruments, reducing water resistance, improving stability, and enabling the overall smooth navigation, facilitating surveys, and obtaining more accurate detection data. Furthermore, the first and second floating platforms are partially hollow structures, which can provide greater buoyancy.

[0029] Furthermore, the bottom end of the second floating platform 520 is provided with an outwardly protruding extension plate, and a marine propeller 530 is installed on the bottom surface of the extension plate to provide propulsion for navigation; the direction can also be reversed by controlling the speed difference between the two marine propellers; it should be noted that marine propellers are common power equipment structures that can be purchased and used on the market, and differential reversing is also a common drive method, which will not be elaborated on in detail.

[0030] More specifically, it adopts a detachable structure that can be adjusted according to actual application scenarios. In addition to being used in combination, the drone can also be detached and used independently for long-distance aerial photography. The first and second floating platforms and support frame below can be constructed into a hull and used independently as a remote-controlled boat. It can be applied to various application scenarios such as hydrological monitoring, underwater three-dimensional topographic surveying, water quality monitoring, water conservancy inspection, and material delivery.

[0031] Furthermore, the first bracket 300 is fixed between the end side walls of the two second floating platforms 520 by bolts, and its top surface is arched upwards at least 10cm higher than the top surface of the support frame 200, so that it is at a certain height above the water surface, thereby reducing water splashing and adhesion from the foundation.

[0032] The junction box 400 is bolted to the top surface of the first bracket 300, with both ends extending towards the second floating platform; as shown. Figure 4 As shown, the junction box 400 has multiple wire holes 410 on both side walls. A wire tube 420 is fixedly installed on the outside of the wire hole 410. The outer wall of the wire tube is threaded for installing a wire cover 430 or a sealing cover 440. The wire cover has a through hole for threading the wire. A ring-shaped wire plug 450 is installed inside the wire tube 420. The protruding wire tube, the built-in wire plug, and the external wire cover can effectively block the wire hole area, further preventing external liquid from entering the interior. The difference between the wire cover and the sealing cover is that the wire cover has a through hole. When threading is required, the wire cover structure is used. When threading is not required, the sealing cover seals the wire tube area. Even if threading is not required, a wire plug must be added inside the corresponding wire tube to further enhance the sealing effect. It should be noted that the diameter of the wire plug hole should be selected according to the diameter of the wire to provide a suitable hole diameter, reduce gaps, and enhance the sealing effect.

[0033] Furthermore, the sidewall of the conduit 420 is provided with multiple slits 421 extending along the axial direction. The length of each slit is not less than half the length of the conduit, and the end of each slit 421 extends to the port of the conduit 420. The multiple slits are arranged in a circumferential array around the axis of the conduit. The length of the through plug 450 is adapted to the length of the conduit 420. The outer wall of the through plug 450 is a frustum-shaped structure, and the diameter of the smaller end is adapted to the inner diameter of the conduit 420. The slit design allows the conduit to be divided into several segments, giving it a certain deformation basis, which facilitates the insertion of the frustum-shaped through plug. Since the diameter of the through plug, except for one end, is larger than the inner diameter of the conduit, when the wire cover is installed, the conduit and the through plug can be squeezed, further strengthening the contact between the through plug and the wire and enhancing the sealing effect.

[0034] The junction box includes a box body and a cover. The top of the box body is open, and a sealing gasket is attached to the bottom surface of the cover. The cover is fixed to the top of the box body with bolts, and the connection is sealed by the sealing gasket. The cover is made of plastic, and the conduit and the box body are integrally molded plastic structures, which facilitates processing and production and also achieves the required sealing and insulation effects. In addition, the conduit part has good deformability to accommodate the wire plug and facilitates subsequent compression deformation, effectively compressing the wire plug to form a better sealing effect. It should be noted that the plastics used include, but are not limited to, one of PP / PE / PVC, all of which are relatively common plastics, and will not be elaborated further.

[0035] Furthermore, such as Figure 2 , Figure 3 As shown, a guide structure 600 is installed on the first bracket 300; the guide structure 600 includes two opposing second brackets 610, which are bolted to the first bracket 300; three rollers 620 are rotatably mounted between the two second brackets 610, and the rollers 620 extend along the length of the junction box 400; one roller is located below the crossbeam of the first bracket and corresponds to the center line of the junction box; the other two rollers are located on both sides of the junction box and are higher than the top surface of the first bracket;

[0036] The guide structure is designed to support the wires, allowing them to be better inserted into the junction box. Especially when there is not enough space for wiring on the same side and the wire needs to be inserted into the hole on the other side, the wire can be routed around the bottom of the roller in the middle and then around to the corresponding roller on the other side. This provides the wire with limited support, making it easy to pull and drag, keeping it in a relatively taut state and preventing it from becoming loose and messy.

[0037] Furthermore, the support frame includes at least two opposing first frame plates, which are mounted on the top surface of the second floating platform. A second frame plate and multiple third frame plates are mounted between the first frame plates, with the second frame plate located in the middle of the first frame plates and the first floating platform mounted on the bottom surface of the second frame plate. The third frame plates have multiple holes for mounting hydrological survey instruments. Of course, corresponding holes can also be provided on the first and second frame plates, not just the third frame plates, and can be set and adjusted according to the actual installation requirements of the survey instruments. In addition, the top surface of the support frame is fixedly provided with upward-protruding upright plates, columns, or slots, which can be used to connect and cooperate with the support feet of the UAV, enabling a stable connection between the two and completing the overall construction.

[0038] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
