Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention discloses an intelligent autonomous water rescue device, which comprises a driving box 1, wherein the driving box 1 is connected with a life buoy body 3 through a connecting box 2;
the driving mechanism in the driving box 1 drives the whole rescue device to realize the functions of advancing and turning. The connecting box 2 is internally provided with an automatic inflation mechanism and auxiliary components such as a motor, a hydraulic pump and infrared induction, and the life buoy body 3 is automatically inflated through the automatic inflation mechanism, so that the inflated life buoy body is matched with the connecting box 2 to form a complete ring.
Fig. 2 is a schematic view of the intelligent autonomous water rescue device in a folded state. The lifebuoy body 3 is folded and stored on two opposite sides of the connecting box 2 before being inflated, the connecting box 2 is designed into a part of a full circle in shape, and the lifebuoy body is matched with the two semicircular ring lifebuoy bodies 3 to form the full circle after being inflated. The electromagnetic induction suction buckle is arranged at the connecting part of the two semicircular ring life rings, and the two semicircular ring life rings are mutually locked through the suction buckle when the inflation is completed, so that the loosening is prevented.
Fig. 3 is a schematic view of a connecting part of a driving box 1 and a connecting box 2 of the intelligent autonomous water rescue device. One side of the connecting box 2 connected with the driving box 1 is designed with a convex circular ring like a bearing cover, the convex circular ring is matched with a bearing in the driving box 1 to limit the circumferential movement of the convex circular ring, meanwhile, the axial displacement of the bearing is limited by the circular hole wall of the convex circular ring, and finally, the box body of the driving box 1 and the box body of the connecting box 2 are fastened by screws. The life buoy body 3 is made of plastic foam materials, and the life buoy body 3 can be connected with the connecting box 2 through glue.
Fig. 4 is a schematic structural diagram of a driving mechanism of the intelligent autonomous water rescue device, wherein the device is placed in a driving box 1 through the matching of angular contact ball bearings on two sides of each shaft and round holes of a box body.
The primary speed reduction of the driving mechanism is realized by meshing a primary speed reduction driving gear 1-1 and a driven gear on a gear shaft 1-2, and the primary speed reduction driving gear 1-1 is positioned on a primary speed reduction output shaft 1-3 through a flat key and a shaft shoulder. The rotating speed of a driving motor 2-6 of the rescue device connected to a first-stage speed reduction output shaft 1-3 is reduced to the rated rotating speed required by the propeller.
Two speed change mechanisms of the driving mechanism are arranged on the left side and the right side of the first-stage speed reduction output shaft 1-3, each speed change mechanism respectively controls one propeller to drive, and the speed difference is generated by controlling the speeds of the propellers on the two sides through the speed change mechanisms to realize steering;
a detailed structural schematic diagram of one side shifting mechanism is shown in fig. 5. The two ends of the gear shaft 1-2 are respectively sleeved with a speed change mechanism driving gear I (small tooth number) 1-4 and a speed change mechanism driving gear II (large tooth number) 1-5, axial positioning is carried out through a shaft sleeve and a shaft shoulder, and circumferential positioning is carried out through a flat key.
The inner hole of the duplicate gear 1-6 is a spline groove, and the duplicate gear 1-6 and the spline shaft 1-7 are mutually matched and circumferentially fixed on the shaft. The spline on the spline shaft 1-7 is a long key, so the dual gear 1-6 can move axially on the spline shaft 1-7.
The shifting fork sleeve 1-8 is sleeved on a connecting shaft sleeve (the connecting shaft sleeve is a connecting shaft sleeve between two gears on the duplicate gear) of the duplicate gear 1-6 and is connected with a piston on the hydraulic cylinder A1-9 through a nut. The electromagnetic valve A1-10 is a five-position three-way valve, and the pushing of a piston rod of the hydraulic cylinder A1-9 can be controlled by changing the valve position, so that the shifting fork sleeve 1-8 is driven to move to realize the position change of the duplicate gear 1-6 on the spline shaft 1-7. The propeller 1-11 is arranged at one end of the spline shaft 1-7. When the position of the duplicate gear 1-6 is meshed with a gear A (two gears of the duplicate gear 1-6, one is the gear A, the other is the gear B, the number of teeth of the gear A is less than that of the gear B) and a driving gear II1-5 of the speed change mechanism, a propeller 1-11 of the speed change mechanism outputs a lower speed; when the dual gear 1-6 is positioned such that the gear B meshes with the variator drive gear I (small number of teeth) 1-4, the variator's propellers 1-11 output a greater speed. In the initial state of the rescue device, a small-tooth-number gear of the duplicate gears 1-6 is meshed with a driving gear (large-tooth-number) 1-5 of the speed change mechanism, namely propellers 1-11 are all in a low-speed state.
Fig. 6 is a schematic view of the internal structure of a connecting box 2 of the intelligent autonomous water rescue device. The two infrared sensors 2-1 are symmetrically arranged in the connecting box 2, the sensed distance signal of the person falling into the water is transmitted to the speed change mechanism in the driving box 1, and the two propellers 1-11 of the speed change mechanism are controlled to work at different speed gears by the electric control part.
The hydraulic pump 2-2 and the hydraulic pump driving motor 2-3 are respectively fixed on two sides of the motor support 2-4 by threads, are placed inside the connecting box 2 after being assembled outside the box body, and are connected with the connecting box 2 by screws through holes at the bottom of the motor support 2-4, so that the assembly can be completed in a relatively narrow space.
The rated rotating speeds of the hydraulic pump 2-2 and the hydraulic pump driving motor 2-3 are the same, the hydraulic pump 2-2 and the hydraulic pump driving motor 2-3 are directly connected through the coupler A2-5, the phenomenon that the size of the device is overlarge due to the use of an additional speed reducing mechanism is avoided, and the space of a box body is saved.
A boss is designed at the bottom of the connecting box 2 and used for installing a driving motor 2-6 of the rescue device, so that the driving motor 2-6 of the rescue device reaches the height matched with a primary speed reduction output shaft 1-3 in the driving box 1, and the driving motor 2-6 of the rescue device is connected with the primary speed reduction output shaft 1-3 through a coupler B2-7.
The hydraulic cylinder B2-8 is connected and supported by a hydraulic cylinder bracket 2-9, the hydraulic cylinder B2-8, the cylinder 2-10 and the plunger 2-11 are assembled outside the box body to form an automatic inflation mechanism and then are placed inside the connecting box 2, and the automatic inflation mechanism is connected with the connecting box 2 through a through hole in the bottom of the hydraulic cylinder bracket 2-9 by a screw, so that the assembly is prevented from being blocked by a narrow space.
When the rescue device works, the hydraulic pump 2-2 sucks liquid in water through the hydraulic pump driving motor 2-5, pushes the liquid into the hydraulic cylinder A1-9 in the driving box 1 and the hydraulic cylinder B2-8 in the connecting box 2, and provides power for a piston of the hydraulic cylinder.
The electromagnetic valve B2-12 is a five-position three-way valve and is connected between the hydraulic pump 2-2 and the hydraulic cylinder B2-8, and the pushing of the piston of the hydraulic cylinder B2-8 can be controlled by changing the valve position, so that the plunger 2-11 is driven to be matched with the vent hole of the cylinder 2-10 to realize the automatic inflation of the life buoy body 3.
Fig. 7 is a schematic structural diagram of an automatic inflation mechanism (except for a hydraulic cylinder and a hydraulic cylinder bracket) of the intelligent autonomous water rescue device. The automatic inflation mechanism mainly comprises a cylinder 2-10 and a plunger 2-11 except a hydraulic cylinder B2-8 and a hydraulic cylinder bracket 2-9. The air cylinder 2-10 is designed into a double-layer structure, the large chamber 2-10a is used for storing liquid gas (the gas is compressed into liquid under a high-pressure state), the small chamber 2-10b is provided with a small chamber through hole 2-10c, one end of a rubber pipe is connected with the small chamber through hole 2-10c, the other end of the rubber pipe is connected with a connecting box through hole 2-13, the gas is conveyed into the life buoy body 3 connected with the connecting box 2 through the rubber pipe, and the life buoy body 3 can be inflated. In addition, the cylinder 2-10 is designed with a hollow sleeve 2-10d at the location where it cooperates with the plunger 2-11. The upper end of the hollow sleeve 2-10d is provided with a large chamber inner vent hole 2-10e communicated with the large chamber 2-10a, the middle end is provided with a small chamber inner vent hole 2-10f communicated with the small chamber 2-10b, and the lower end is provided with an outer vent hole 2-10g communicated with the outside. Two ends of the plunger 2-11 are respectively designed into a cone-shaped rubber plug 2-11a and a round-truncated-cone-shaped rubber plug 2-11B which can be compressed and deformed, and the tail end 2-11c of the plunger is provided with a through hole and is in threaded connection with the piston of the hydraulic cylinder B2-8. When the piston of the hydraulic cylinder B2-8 drives the plunger 2-11 to move downwards, the truncated cone-shaped rubber plug 2-11B is extruded to seal the outer vent hole 2-10g of the cylinder 2-10; the conical rubber plug 2-11a moves downwards to enable the gas in the large chamber 2-10a to enter the small chamber 2-10b through the vent hole 2-10e in the large chamber and the vent hole 2-10f in the small chamber to inflate the life buoy body 3. On the contrary, when the piston of the hydraulic cylinder B2-8 pushes the plunger to move upwards, the conical rubber stopper 2-11a is extruded to seal the vent hole 2-10e in the large chamber, and the life buoy body 3 cannot be inflated. Therefore, the opening and closing of the air vents 2-10g outside the air cylinders 2-10 and the air vents 2-10e inside the large chamber are controlled through the reciprocating motion of the plungers, so that the life buoy body 3 is inflated, and meanwhile, air leakage to other box bodies can be avoided. In addition, the side surface of the cylinder 2-10 is provided with an inflatable ring hole 2-10h, and a sealing gasket is arranged in the inflatable ring hole 2-10h, so that the cylinder 2-10 can be inflated for multiple times. When the cylinder needs to be inflated, the external inflation tank tightly presses the sealing gasket to jack the sealing gasket, and gas can enter the large chamber 2-10a of the cylinder from the inflation tank because the internal pressure of the inflation tank is greater than the internal pressure of the cylinder 2-10. When the external inflation tank is pulled out after the air cylinder is inflated, the air pressure presses the sealing gasket against the inflation ring hole for 2-10 hours because the internal pressure of the air cylinder 2-10 is greater than the external air pressure, thereby ensuring that the air cylinder cannot leak air.
The working process of the intelligent autonomous water rescue device comprises the following steps: (1) the rescue device is in the uninflated state shown in fig. 2 and is semi-submerged when waiting for rescue. (2) When an infrared sensor 2-1 in the rescue device detects that people falling into water exist in a water area within a certain range where the rescue device is located (the rescue device can be activated by the rescue personnel to avoid mistakenly rescuing people not falling into water), the electric control part is started, and a propeller 1-11 is driven to drive the drowning person to be located through a drive motor 2-6 of the rescue device. When the infrared sensor 2-1 on one side senses that the position of a person falling into the water is far from the other side in the driving process of the rescue device, the rescue device needs to turn towards the opposite side. The control part receives the signal instruction, sends an instruction to the drive mechanism speed change mechanism far from the person falling into the water after program processing, namely controls the side electromagnetic valve A1-10 to change the valve position, so that the piston of the hydraulic cylinder A1-9 pushes the duplicate gear 1-6 to change the transmission ratio of the meshing gear, the side propeller 1-11 is converted into a large rotating speed, and the side propeller 1-11 is still in a small rotating speed, thereby generating differential speed and realizing steering. When the distance between the two infrared sensors 2-1 and the person falling into the water is the same, namely the rescue device is opposite to the person falling into the water, the rescue device needs to go straight. The control part controls the electromagnetic valve A1-10 which changes the valve position to return to the original valve position, the duplicate gear 1-6 is pushed back to enable the propellers 1-11 on the two sides to be at a low rotating speed, and the rescue device runs linearly. (3) When the rescue device runs to the position near a person falling into water, the control part disconnects the driving mechanism circuit and starts the automatic inflation mechanism circuit to perform automatic inflation. Because the rescue device is semi-submerged before inflation, the life buoy body 3 is just self-encircled under the armpit of a person falling into water while automatic inflation is carried out, and after inflation is finished, the two semi-circular rescue buoys are locked by the electromagnetic induction suction buckles to form a whole circle and drive the person falling into water to float on the water surface. (4) After rescue is finished, the infrared sensor 2-1 cuts off the induction to the person falling into the water, and then induces the sensor carried by the rescue personnel on the shore, and the driving mechanism is started to return to the safe shore. The principle of the return driving mechanism is the same as that of the going journey, when the rescue device brings a person falling into water to the shore, the driving mechanism stops, and the person falling into water is rescued by rescue personnel on the shore.
As the rescue device is in a semi-submerged state, the driving box 1 and the connecting box 2 are made of martensitic stainless steel, the material is low in density and high in strength, the whole device has the characteristics of large volume and light weight, and the whole rescue device is low in density and is semi-submerged. If the purpose of semi-submergence cannot be achieved in the test process, the rescue device can be semi-submerged under water by tying a balloon on the rescue device box body or sticking a foam plate and the like.
