Description

Technical Field

[0001] The present invention specifically relates to a lifting flying device based on water flow force, and belongs to the technical field of flying devices. Background Art

[0002] In modern agriculture, aerial work equipment is needed to spray pesticides on large areas of farmland and monitor crop growth, in order to improve agricultural production efficiency and accuracy. In firefighting and rescue scenarios, traditional firefighting equipment faces height restrictions when dealing with high-rise building fires. Aerial work equipment can carry firefighting supplies to higher locations to extinguish fires, buying time for rescue efforts. Regarding high-altitude cleaning, cleaning the exterior walls of urban high-rise buildings is difficult and dangerous, but aerial work equipment can complete cleaning tasks safely and efficiently. In the field of environmental monitoring, aerial work equipment needs to be equipped with various sensors to monitor air quality, water quality, and the ecological environment in real time to obtain more comprehensive and accurate data.

[0003] Aerial tethering systems, as key equipment enabling low-altitude, long-term, airborne operations, play a vital role in these areas. Most existing aerial tethering systems utilize a fan system as a lift platform, relying on the thrust generated by the fan to achieve lift and hold. To achieve specific operational functions, such as firefighting in fire rescue operations and pesticide spraying in modern agriculture, the platform must be equipped with corresponding functional devices, such as water sprinklers for firefighting and pesticide sprayers for agricultural operations. This design results in an extremely complex system structure and a significant increase in the number of components. The numerous components not only increase the overall weight, increase the lifting burden on the platform, and reduce the system's energy efficiency, but also significantly increase the equipment's manufacturing costs, including component procurement, assembly, and subsequent maintenance costs. Furthermore, the complex structure increases the probability of equipment failure, reduces system stability and reliability, and introduces numerous inconveniences in practical applications. Summary of the Invention

[0004] The purpose of the present invention is to provide a lifting flying device based on water flow force to address the shortcomings of the existing technology.

[0005] The present invention achieves the above-mentioned purpose through the following technical scheme: a lifting and flying device based on water flow force, comprising a hollow box, a lifting assembly provided on the surface of the hollow box, the lifting assembly comprising a connecting rod fixedly connected to the four corners of the hollow box, the connecting rod being fixedly connected to a rectangular block at one end away from the hollow box, a ball sleeve being provided in a ball groove opened inside each of the rectangular blocks, a middle column tube being connected inside the ball sleeve, the top of the middle column tube being fixedly connected to an upper cone tube, the top of the upper cone tube being fixedly connected to an upper column tube, the bottom of the middle column tube being fixedly connected to a lower cone tube, a composite tube being inserted into the bottom surface of the hollow box, and a plurality of air holes being provided on the surface of the middle column tube below the ball sleeve.

[0006] By adopting the above technical solution, the upper column, upper cone, middle column and lower cone form a structure similar to a Venturi tube. The upper column guides the fluid to enter smoothly, the upper cone accelerates the fluid and reduces the pressure, the middle column uses low pressure to inhale air through the air holes to achieve air-water mixing, and the lower cone restores the fluid pressure. Combined with the water flow transported by the composite pipe, the lifting assembly can not only generate lifting force through water jets, but also complete water spraying operations without the need for additional power, achieving multiple goals at one stroke.

[0007] Preferably, the rectangular block and the ball sleeve are movably connected, the ball sleeve is fixedly connected to the middle column tube, the top fixed sleeve of the upper column tube is provided with an upper connecting tube, the end of the upper connecting tube away from the upper column tube is inserted into the through hole opened on the upper surface of the hollow box, and the upper connecting tube is retractable.

[0008] By adopting the above technical solution, the movable connection between the rectangular block and the ball sleeve allows the center column tube to flexibly adjust its angle, and the telescopic characteristics of the upper connecting pipe adapt to the angle changes of the center column tube, ensuring that the water flow in the hollow box is stably delivered to each lifting component, thereby ensuring the stable power output of the lifting component in different postures.

[0009] Preferably, the composite pipe is a three-in-one ultra-light composite hose for water and electricity.

[0010] By adopting the above technical solution, the composite pipe serves as a three-in-one ultra-light composite hose for water, electricity and telecommunications. Compared with traditional pipes, its weight is greatly reduced, which reduces the load on the device. At the same time, its internal integrated water transmission channels, wires and optical cables can synchronously transmit water flow, electricity and control signals, simplifying the connection structure of the device, improving the system integration, and ensuring the coordinated operation of various parts such as lifting components and steering components.

[0011] The two ends of the two middle rods are respectively fixedly connected to the ball rings at corresponding positions, and the two ends of the two middle rods are respectively fixedly connected to the ball rings at corresponding positions. The two bending rods and the two middle rods form a rectangular structure, and the top of the L-shaped rod is fixedly connected to one of the bending rods.

[0012] By adopting the above technical solution, push rod one and push rod two drive the L-shaped rod, bending rod and middle rod to move through telescoping. The movable connection between ball sleeve two and ball ring allows the upper column tube to adjust its angle as the rectangular structure deforms, so that the steering assembly can accurately control the injection direction of each lifting component and realize the forward, backward, left and right movement and posture adjustment of the device.

[0013] Preferably, the steering assembly further comprises an insertion strip, wherein the two slots opened on the bottom surface of the L-shaped seat are respectively inserted with an insertion strip, the insertion strip is fixedly connected to the upper surface of the hollow box, the L-shaped seat and the insertion strip are slidably connected, and the push rod 2 and the insertion strip are both placed horizontally on the upper surface of the hollow box.

[0014] By adopting the above technical solution, the cooperation between the insert and the slot provides a guide for the sliding of the L-shaped seat, ensuring smooth movement when the push rod 2 drives the steering assembly, avoiding the L-shaped seat offset affecting the direction of the force of the push rod 1, and improving the accuracy of steering control.

[0015] Preferably, a wire-taking assembly is provided at the bottom end of the composite tube, and the wire-taking assembly includes a chassis, an L bracket, a winding wheel, a longitudinal rod, a T-block, an outer ring sleeve, a motor, a gear, an inner gear ring and a rectangular rod. The upper surface of the chassis is fixedly connected to the L bracket, the upper surface of the chassis is fixedly connected to the rectangular rod, the rectangular rod is inserted into a rectangular hole opened inside the winding wheel, the winding wheel and the rectangular rod are slidably connected, the outer ring surface of the bottom of the winding wheel is sleeved with an outer ring sleeve, the inner part of the outer ring sleeve is fixedly connected to the inner gear ring, and the inner part of the inner gear ring is meshed with a gear. A motor is installed on the bottom surface of the winding wheel, and the end of the motor output shaft is fixedly connected to the gear. A longitudinal rod is longitudinally inserted into the longitudinal groove opened on the outer ring surface of the outer ring sleeve, and the longitudinal rod and the outer ring sleeve are slidably connected.

The bottom end of the longitudinal rod is fixedly connected to the T-shaped block, and the composite tube passes through the circular hole 1 opened at the top of the L bracket and the circular hole 2 opened at the top of the longitudinal rod. The composite tube is slidably connected to the L bracket and the longitudinal rod, and the composite tube is wrapped around the surface of the winding wheel.

[0016] By adopting the above technical solution, the motor drives the inner gear ring and the outer ring sleeve to rotate through the gears, driving the longitudinal rod to rotate around the winding wheel. Cooperating with the guidance of the L bracket, the composite pipe is wound on the winding wheel or released in an orderly manner. The sliding of the T-block and the T-ring groove ensures the smooth movement of the longitudinal rod, and the composite pipe is automatically retracted and released according to the flight altitude of the device, avoiding entanglement or pulling of the pipeline.

[0017] Preferably, the wire-winding assembly further comprises a spiral strip and a ring, the interior of the winding wheel is fixedly connected to the ring, the surface of the outer ring of the ring is fixedly connected to the spiral strip, a spiral groove is provided on one side of the longitudinal rod close to the outer ring sleeve, and the spiral strip is inserted into the interior of the spiral groove.

[0018] By adopting the above technical solution, the spiral strips on the collar cooperate with the spiral grooves of the longitudinal rod, so that the longitudinal rod moves axially when rotating around the winding wheel, driving the composite pipe to be evenly wound around the surface of the winding wheel, avoiding waste of storage space or poor release caused by pipe stacking.

[0019] Preferably, the wire-winding assembly further comprises balls, an outer raceway is provided on the outer ring surface at the bottom end of the winding wheel, an inner raceway is provided inside the outer ring sleeve, balls in a circular array are arranged between the inner raceway and the outer raceway, and the outer ring sleeve is rotationally connected to the winding wheel.

[0021] Preferably, the wire-winding assembly further includes a disc seat and a support rod. The disc seat is provided below the chassis, and a plurality of support rods are provided between the disc seat and the chassis. One end of the composite tube passes through the bottom end of the winding wheel and the surface of the chassis, and extends from between the chassis and the disc seat to the outside. The water pipe at one end of the composite tube away from the hollow box is connected to the vehicle-mounted high-pressure pump and hydraulic buffer tank provided externally.

[0022] By adopting the above technical solution, the disc seat provides stable support for the chassis through the support rod, ensuring the stability of the overall structure of the take-up assembly. At the same time, the connection between the composite pipe and the external on-board high-pressure pump and hydraulic buffer tank ensures the continuous supply of high-pressure water flow, making the device's endurance unrestricted, and the flight altitude of the hollow box can be changed by controlling the delivery pressure of the on-board high-pressure pump and hydraulic buffer tank.

This design does not require an additional power device and directly uses the ejected water flow as power, which not only has extremely low energy consumption, but can also complete lifting and water spraying operations at the same time, achieving multiple goals at one stroke, and effectively solving the problems of high energy consumption and single function of traditional devices;

[0024] The coordinated action of push rods 2 and 1 can drive the movement of components such as the bending rod and the middle rod, thereby changing the inclination angles of the upper column and the middle column. Ball sleeve 1 rotates in ball groove 1, and ball sleeve 2 rotates in the ball ring, ensuring the smoothness of the adjustment process. At the same time, the sliding of the L-shaped rod inside the rectangular sleeve avoids movement obstruction, enabling the device to fly forward, backward, left, and right, and stable control of the flight attitude, greatly improving the device's controllability and operational flexibility, and can adapt to operational needs in different scenarios.

[0025] The motor drives the gear to rotate, driving the inner gear ring and the outer ring sleeve to rotate, causing the longitudinal rod to rotate around the winding wheel, thereby winding the composite tube on the winding wheel to complete the storage. At the same time, the cooperation between the spiral strip and the spiral groove allows the longitudinal rod to move along the axis of the winding wheel during rotation, ensuring that the composite tube is evenly wound. The sliding of the T-block in the T-ring groove and the sliding of the rectangular rod in the rectangular hole ensure the smooth movement of the winding wheel. The length of the composite tube can be flexibly adjusted according to the flight altitude of the device, avoiding problems such as entanglement and dragging of the composite tube, ensuring the safety and stability of the device operation, and the storage process is highly automated, saving manpower.

[0026] A three-in-one ultra-light composite hose combining water, electricity and information is used as the composite pipe. It is lightweight and can simultaneously transmit water, electricity and information, simplifying the system structure, reducing the overall weight of the device and further improving the lifting efficiency. The composite pipe is connected to an external vehicle-mounted high-pressure pump and hydraulic buffer tank, which can continuously obtain high-pressure water flow, making the device's endurance unlimited and enabling continuous operation for a long time.

[0051] The bottom end of the composite pipe 26 is provided with a take-up assembly 4, which comprises a bottom disc 41, an L bracket 42, a winding wheel 43, a longitudinal rod 46, a T-shaped block 47, an outer ring sleeve 410, a motor 412, a gear 413, an inner tooth ring 414 and a rectangular rod 417. The upper surface of the bottom disc 41 is fixedly connected with the L bracket 42. The upper surface of the bottom disc 41 is fixedly connected with the rectangular rod 417.

[0054] The wire-reeling assembly 4 also includes a disc seat 418 and a support rod 419. The disc seat 418 is arranged below the chassis 41, and multiple support rods 419 are arranged between the disc seat 418 and the chassis 41. One end of the composite pipe 26 passes through the bottom end of the winding wheel 43 and the surface of the chassis 41, and extends to the outside from between the chassis 41 and the disc seat 418. The water pipe at the end of the composite pipe 26 away from the hollow box 1 is connected to the vehicle-mounted high-pressure pump and hydraulic buffer tank arranged outside. The disc seat 418 provides stable support for the chassis 41 through the support rod 419, ensuring that the overall structure of the wire-reeling assembly 4 is stable. At the same time, the connection between the composite pipe 26 and the external vehicle-mounted high-pressure pump and hydraulic buffer tank ensures the continuous supply of high-pressure water flow, so that the device's endurance is not limited, and the flight altitude of the hollow box 1 can be changed by controlling the delivery pressure of the vehicle-mounted high-pressure pump and the hydraulic buffer tank.

[0055] Working principle: The lifting assembly 2 is connected to the composite pipe 26 through the vehicle-mounted high-pressure pump, the hydraulic buffer tank, and the composite pipe 26, so that the liquid is injected into the interior of the hollow box 1, and the liquid inside the hollow box 1 flows into the interior of the upper column 29 through the upper connecting pipe 23. The upper column 29 is a cylindrical structure and is adapted to the inner diameter of the upper connecting pipe 23, which is used to guide the fluid to enter smoothly. The upper cone 210 is conical, so that the fluid flow rate gradually increases and the pressure decreases accordingly. The middle column 28 is cylindrical and is the part with the smallest diameter. The fluid flow rate here reaches The surface of the middle column 28 is provided with air holes, which can be used to suck external gas. The low pressure of the middle column 28 can suck in air and achieve gas-water mixing. The lower cone 27 is also conical, which allows the fluid flow rate to gradually decrease and the pressure to be restored, thereby achieving pure water acceleration and gas-water mixing efficiency, and then realizing the nozzle array lifting flight device powered by water flow. The array is composed of several adjustable nozzles as a platform, and the ejected water flow is directly used as the power to achieve lifting and water spraying, achieving multiple goals at one stroke without the need for other power;

[0056] When the push rod two 39 and the push rod one 36 are powered on, the push rod two 39 is started by the external controller, and then the L-shaped seat 37 can be pushed to slide on the surface of the plug strip 38. The movement of the L-shaped seat 37 drives the push rod one 36 to move synchronously, and then drives the rectangular sleeve 35 and the L-shaped rod 34 to move synchronously in the horizontal direction. The push rod one 36 is started by the external controller, and then the rectangular sleeve 35 is driven to move, and then the rectangular sleeve 35 and the L-shaped rod 34 are driven to move in the vertical direction. The horizontal movement of the L-shaped rod 34 drives the bent rod 31 and the middle rod 32 to move synchronously, and then drives the upper column cylinder 29 to move. In the process of movement, the upper column cylinder 29 makes the ball sleeve one 25 rotate inside the ball groove one 24, and then the inclination angles of the middle column cylinder 28, the lower cone cylinder 27, the upper cone cylinder 210 and the upper column cylinder 29 are offset to the direction in which the bent rod 31 moves. In the process of adjusting the inclination angles, the ball sleeve two 311 rotates inside the ball ring 33 to avoid the rotation of the upper column cylinder 29 causing obstruction. In the process of synchronous inclination, the height of the bent rod 31 changes, and then the L-shaped rod 34 slides in the rectangular sleeve 35 in the vertical direction to avoid obstruction of the inclination movement of the upper column cylinder 29. By changing the inclination angles of the upper column cylinder 29, the upper cone cylinder 210, the middle column cylinder 28 and the lower cone cylinder 27, the flight attitude control and the forward and backward flight can be realized. By changing the pressure adjustment of the vehicle-mounted high-pressure pump and the hydraulic buffer tank, the adjustment of the liquid flow can be realized, and then the height adjustment of the flight can be realized, and the use effect of the flight device is improved.

[0057] The arrangement of the take-up assembly 4 facilitates the flight of the hollow box 1 to the direction of the L bracket 42 when the flight height is lowered. The motor 412 is powered to operate, and the motor 412 is started by the external controller. The operation of the motor 412 drives the gear 413 to rotate. The rotation of the gear 413 drives the inner tooth ring 414 connected therewith to rotate. The rotation of the inner tooth ring 414 drives the outer ring sleeve 410 to rotate synchronously. When the outer ring sleeve 410 rotates, the longitudinal rod 46 rotates outside the winding wheel 43 around the axis of the winding wheel 43. Since the composite tube 26 penetrates the circular hole one at the top of the L bracket 42 and the circular hole two at the top of the longitudinal rod 46, the longitudinal rod 46 makes the composite tube 26 wind around the surface of the winding wheel 43 in the process of rotating around the winding wheel 43, and then the effect of storing the composite tube 26 is realized.

[0058] The cam 46 is rotated to move the cam 46 relative to the take-up wheel 43 so that the tube 26 is wound around the take-up wheel 43. The cam 46 is rotated to move the cam 46 relative to the take-up wheel 43 so that the tube 26 is wound around the take-up wheel 43. The cam 46 is rotated to move the cam 46 relative to the take-up wheel 43 so that the tube 26 is wound around the take-up wheel 43.

[0059] When the hollow box 1 increases its flying height or flies in a direction away from the L bracket 42 , the traction force of the hollow box 1 can drive the winding wheel 43 to rotate automatically, thereby achieving the effect of releasing the composite tube 26 to adapt to the flying height of the hollow box 1 .
