Description

Technical Field

[0001] This invention belongs to the field of water rescue technology, and relates to the manufacture of underwater rescue equipment, specifically a surface rescue device. Background Technology

[0002] Water rescue equipment used for fire rescue mainly includes life rings, rescue ropes, rescue boats and other rescue equipment. As a tool for quickly reaching the rescue site, rescue boats can carry rescue personnel and equipment, making it convenient to carry out rescue operations on the water and transfer people who have fallen into the water to a safe location. Most existing mobile robots are only suitable for surface rescue needs and cannot perform underwater rescues. Among the existing technologies, Chinese patent with publication number CN119749809A discloses a U-shaped snorkeling rescue robot that does not require external suction. When using this technology, seawater in the ballast tank is discharged to the outside, and buoyancy is increased by reducing the amount of ballast water to achieve floating. The discharge of seawater takes a period of time and cannot obtain a large and sudden buoyancy gain in a short period of time, which can easily delay the golden rescue time. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention aims to provide a water rescue device. This water rescue device is equipped with a control device and a counterweight structure, enabling the device to float and sink, thereby facilitating both surface and underwater rescues. By installing the device, the counterweight structure can be discarded, allowing the device to achieve a significant and sudden increase in buoyancy in a short period of time, thereby enabling people who have fallen into the water to surface as quickly as possible and increasing their chances of survival.

[0004] The technical solution adopted by this water rescue device to solve its technical problems is as follows: A water rescue device is provided, including a float, a moving device that drives the float to move, a water tank inside the float, and a control device that controls the water volume in the water tank inside the float. Two semi-circular clamps are provided on one side of the float, and an adjustment device is provided on the float to adjust the position of the two clamps. The floating hull is equipped with a counterweight structure, and the floating hull is equipped with an installation device for mounting the counterweight structure and detaching it. The floating hull contains a main control board that controls the moving device, control device, adjustment device, and detachment device. The floating hull also contains a power supply that provides power to the moving device, control device, adjustment device, detachment device, and main control board. The main control board is equipped with a wireless control module.

[0005] Furthermore, the mobile device includes two first thrusters, which are fixedly installed on the front and rear sides of the floating hull and are horizontally positioned.

[0006] Furthermore, the control device includes a piston plate, a connecting hose, a connecting pipe, a solenoid valve, and a bidirectional air pump. The piston plate is disposed inside the water tank and can slide along it. One side of the water tank is fixedly connected to one end of the connecting hose and they are interconnected. The connecting hose passes through the float and is fixedly connected. The connecting pipe is fixedly connected to and connects the other side of the water tank and one end of the bidirectional air pump. The solenoid valve is fixedly installed on the connecting pipe.

[0007] Furthermore, a second thruster is fixedly installed on the front and rear sides of the floating hull, and the second thruster is vertically arranged.

[0008] Furthermore, the adjustment device includes four hinge rods and a first electric push rod. One end of each of two hinge rods, one above the other, is fixedly installed on the outer periphery of the clamping plate. The other end of the hinge rod is hinged to the float via a hinge frame. Both ends of the first electric push rod are fixedly installed with hinge rings. A hinge shaft passes through each hinge ring and is located between the corresponding hinge rods. The hinge shafts are fixedly connected to the corresponding hinge rods at both ends.

[0009] Furthermore, airbags are fixedly installed on the inner side of the clamps.

[0010] Furthermore, the counterweight structure includes a counterweight column with an inner cavity. A winding wheel is rotatably installed inside the inner cavity. One end of a connecting rope is fixedly connected to the winding wheel, and the connecting rope is wound around the winding wheel. A vertical groove is opened on one side of the outer circumference of the counterweight column, and a float is installed in the vertical groove. The connecting rope passes through the counterweight column and is fitted with a gap. The other end of the connecting rope is fixedly connected to the float.

[0011] Furthermore, the installation device includes a mounting hole, a guide groove, a slot, and two second electric actuators. The mounting hole is opened in the float, the guide groove is opened on the front and rear sides of the counterweight column, and both the top and bottom surfaces of the guide groove are open. The slot has a side close to the guide groove. The second electric actuators are fixedly installed on the front and rear sides of the inner wall of the mounting hole, respectively. The fixed end of the second electric actuator is located in the guide groove, and the movable end of the second electric actuator is located in the slot.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention provides a water rescue device. When placed in water, the device can be moved by a movable device to quickly approach a person who has fallen into the water. If the person is on the surface, the clamping plate can be moved by an adjusting device to clamp the person, thus moving them towards the shore. If the person is underwater, water can be pumped into a tank by a control device, causing the device to sink. The clamping plate can then be moved by an adjusting device to clamp the person, and the water can be discharged by a control device. The counterweight structure can be detached by an installation device to further reduce the weight of the device, thereby accelerating its buoyancy and allowing the person to surface as quickly as possible. Compared with the prior art, this invention has a control device and a counterweight structure, enabling it to float and sink, thus allowing for both surface and underwater rescues. The counterweight structure can be discarded by the installation device, allowing the device to gain a significant and sudden increase in buoyancy in a short time, thereby increasing the chances of survival for the person who has fallen into the water.

[0013] 2. An example of the present invention is a water rescue device that supplies power to and turns on the first thruster, which can move the buoy. By controlling the power of the two first thrusters, the forces on the front and rear sides of the buoy can be different, thereby enabling the buoy to turn.

[0014] 3. An example of the water rescue device of the present invention can control the solenoid valve and the bidirectional air pump through the control motherboard. When the solenoid valve is opened, the bidirectional air pump can draw air from the float into the water tank or out of the water tank, thereby pushing the piston plate to move. The movement of the piston plate can cause water to enter the water tank or be discharged from the water tank along the connecting hose, thereby realizing the regulation of the water volume in the water tank.

[0015] 4. An example of the water rescue device of the present invention can provide a certain amount of power for the buoyancy of the floating hull by means of a second thruster, which can increase the buoyancy speed during rescue and make it easier to quickly bring the person who fell into the water to the surface.

[0016] 5. An example of the water rescue device of the present invention can drive the hinge rod to rotate by controlling the extension and retraction of the first electric push rod, thereby enabling the hinge rod to rotate synchronously relative to each other or in opposite directions, thereby driving the clamping plate to move. The adjustment device has a simple structure and is easy to use.

[0017] 6. An example of the present invention is a water rescue device in which the airbag fits snugly against the human body and is suitable for people of different body types who have fallen into the water.

[0018] 7. In a water rescue device according to the present invention, when the counterweight structure falls off, the float can rise due to the influence of buoyancy, and the counterweight column will sink, thereby allowing the connecting rope to be released from the winding wheel, which facilitates subsequent retrieval and salvage.

[0019] 8. In a water rescue device according to the present invention, a counterweight column is placed in the mounting hole and the slot is aligned with the corresponding second electric push rod. The extension of the two second electric push rods is controlled so that their movable ends are inserted into the slots, thereby achieving the function of installation and fixation. When in use, the two electric push rods are controlled to retract, so that the counterweight structure falls off under the action of gravity. Attached Figure Description

The power supply is only electrically connected to the control mainboard. The power control module of the control mainboard performs power adaptation and power supply control for the moving device, control device, adjustment device, disengagement device, and short-range short-wave infrared thermal detector. The control mainboard is equipped with a wireless control module.

[0025] When this invention is placed in water, it can be moved by a moving device, allowing it to quickly approach a person who has fallen into the water. If the person is on the surface, the clamping plate 3 can be moved by an adjusting device, clamping the person and pulling them towards the shore. If the person is underwater, water can be pumped into the water tank 2 by a control device, causing the invention to sink. The clamping plate 3 can then be used to clamp the person again by the adjusting device, and the water can be discharged by the control device. The counterweight structure can be detached by the installation device, further reducing the weight of the invention and accelerating its buoyancy, allowing the person to surface as quickly as possible. Compared with existing technologies, this invention has a control device and a counterweight structure, enabling it to float and sink, thus facilitating both surface and underwater rescues. The counterweight structure can be discarded by the installation device, allowing the invention to gain a significant and sudden increase in buoyancy in a short time, thus increasing the chances of survival for the person who has fallen into the water.

[0026] like Figure 1As shown, in a further preferred embodiment, the moving device includes two first thrusters 4. Each first thruster 4 is an axial-flow water jet propulsion device.

Powering and turning on the first thrusters 4 allows the float hull 1 to move. By controlling the power of the two first thrusters 4, the forces on the front and rear sides of the float hull 1 can be different, thereby enabling the float hull 1 to steer.

[0027] like Figure 1 and 2 As shown, in a further preferred embodiment, the control device includes a piston plate 5, a connecting hose 6, a connecting pipe 7, a solenoid valve 8, and a two-way air pump 9.

The piston plate 5 is disposed inside the water tank 2 and can slide along it. One end of the connecting hose 6 is fixedly connected to one side of the water tank 2 and they are interconnected. The connecting hose 6 passes through the float 1 and is fixedly connected. The other end of the connecting hose 6 is fixedly connected to a stainless steel flared pipe. The flared pipe structure facilitates the entry of water into the water tank 2 and the discharge of water from the water tank 2. In addition, it can... The weight is increased, the connecting hose 6 hangs naturally, and the flared tube is in the water. Finally, a filter screen can be added to the flared tube to prevent large particles of impurities from entering the water tank 2. The connecting pipe 7 is fixedly connected to and connects the other side of the water tank 2 and one end of the bidirectional air pump 9. The water tank 2 is equipped with a bellows airbag. The connecting pipe 7 is connected to and communicates with the bellows airbag. The bellows airbag can prevent air leakage at the piston plate 5 from affecting the use of this control device. The solenoid valve 8 is fixedly installed on the connecting pipe 7. The water tank 2 is equipped with a pressure valve, which can detect the pressure in the water tank 2. The control board can control the solenoid valve 8 and the bidirectional air pump 9. When the solenoid valve is opened, the bidirectional air pump 9 can draw air from the float 1 into or out of the water tank 2, which can push the piston plate 5 to move. The movement of the piston plate 5 can make water enter or exit the water tank 2 along the connecting hose 6, thereby realizing the water volume regulation in the water tank 2.

[0028] like Figure 1 and 2 As shown, in a further preferred embodiment, a second thruster 10 is fixedly installed on the front and rear sides of the float hull 1, respectively. The second thruster 10 is electrically connected to the control main board and is vertically positioned.

The hinge shafts are located between the corresponding hinge rods 11, and the distance between the hinge shaft and the corresponding hinge frame is equal. The hinge shafts are fixedly connected to the corresponding hinge rods 11 at both ends. By controlling the extension and retraction of the first electric actuator 12, the hinge rods 11 can be rotated, thereby allowing the hinge rods 11 to rotate synchronously relative to each other or in opposite directions, thus moving the clamping plate 3. This adjustment device has a simple structure and is easy to use.

[0030] like Figure 1 As shown, in a further preferred embodiment, airbags 13 are fixedly installed on the inner side of the clamping plate 3, and contact temperature sensors are provided on the clamping plate 13. The contact temperature sensors can measure temperature after contacting the human body.

[0031] like Figure 1-4 As shown, in a further preferred embodiment, the counterweight structure includes a counterweight column 14, with an inner cavity 15 inside the counterweight column 14. The inner cavity 15 has a connecting hole that communicates with the outside. A winding wheel 16 is rotatably mounted inside the inner cavity 15. The mounting shaft of the winding wheel 16 passes through the counterweight column 14 and is rotatably connected to it. The mounting shaft of the winding wheel 16 has an internal hexagonal groove, which facilitates the rotation of the winding wheel 16 by a hexagonal handle, thereby winding up the connecting rope 17. One end of the connecting rope 17 is fixedly connected to the winding wheel 16, and the connecting rope 17 is wound around the winding wheel 16. A vertical groove 18 is opened on one side of the outer circumference of the counterweight column 14, and a float 19 is provided in the vertical groove 18. The connecting rope 17 passes through the counterweight column 14 and is fitted with a clearance. The other end of the connecting rope 17 is fixedly connected to the float 19. When the counterweight structure falls off, the float 19 will rise due to buoyancy, and the counterweight column 14 will sink, so that the connecting rope 17 can be released from the winding wheel 16, which will facilitate subsequent recovery and salvage.

[0032] like Figure 1-4As shown, in a further preferred embodiment, the installation device includes a mounting hole 20, a guide groove 21, a slot 22, and two second electric actuators 23.

The two slots 22 have a horizontally overlapping portion. The movable end of the second electric actuator 23 is located within this horizontally overlapping portion of the slots 22. In use, one of the second electric actuators 23 is controlled to align with the slot 22 with the bottom opening. The movable end of one of the second electric actuators 23 can contact and support the top surface of the slot 22 with the bottom opening. Then, the other electric actuator 23 can be extended. This makes it more convenient to use, as there is no need to adjust the position of the slots 22. The counterweight column 14 is placed in the mounting hole 20, aligning the slot 22 with the corresponding second electric actuator 23. Controlling the extension of both second electric actuators 23 allows their movable ends to be inserted into the slots 22, thus achieving the function of installation and fixation. In use, controlling the retraction of the two electric actuators 23 allows the counterweight structure to fall under the action of gravity.
