Description

Technical Field

[0001] The present invention belongs to the technical field of rescue robots and relates to a rescue material transportation robot. Background Art

[0002] Rescue material transportation robots have a high degree of autonomy and flexibility, and can perform rescue tasks in various complex and dangerous environments, greatly improving the rescue efficiency and safety. They are an important technology in the field of emergency rescue and play an increasingly important role at the disaster site. During the transportation of rescue materials, for medicine bottles made of glass, if only cold storage substances such as ice bags are simply placed into the insulation box containing the medicine bottles. Due to the complex rescue environment, the transportation robot will inevitably encounter bumps, which will cause the medicine bottles to collide or be squeezed with each other, easily causing the medicine bottles to break and resulting in waste. And when refrigerating drugs, in order to ensure the stability and effectiveness of the drugs, the drugs need to be within a suitable temperature range. Too high or too low a temperature will have an adverse effect on the drugs. When simply placing cold storage substances such as ice bags into the insulation box containing the medicine bottles, the speed at which the ice cubes release cold air cannot be automatically adjusted according to the number of medicine bottles placed.

This allows cold air to enter the telescopic cylinder and ensures the refrigeration effect of the medicine bottle.

[0018] 3. When no medicine bottle is placed, the blocking block is at the front end of the storage cavity to seal the storage cavity, preventing cold air from flowing out and pre-cooling the telescopic cylinder at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 - 13 As shown, the technical solution adopted by the present invention is as follows: A rescue material delivery robot includes a robot body, a telescopic cylinder and a blocking block 28. The robot body includes a moving part 1 and a storage part 2, and the storage part 2 is installed on the moving part 1. The moving part 1 drives the storage part 2 to move. The front side of the storage part 2 is opened and closed with a door 3.

[0035] An ice storage cavity 4 is provided at the front side of the storage part 2, and a heat preservation cover 5 is provided at the front end of the ice storage cavity 4. The heat preservation cover 5 is used to seal the front end of the ice storage cavity 4 to prevent the cold air in the ice storage cavity 4 from leaking out. A diffusion cavity 6 is provided at the rear of the storage part 2, and the diffusion cavity 6 is communicated with the rear end of the ice storage cavity 4.

[0036] A vertical plate is fixed at the rear end of the ice storage chamber 4, and a clearance chamber is formed between the vertical plate and the inner wall of the ice storage chamber 4. A sealing plate 7 is provided in the clearance chamber for sealing and sliding, and a first spring 8 is fixedly connected between the sealing plate 7 and the top wall of the ice storage chamber 4. A vent hole communicating with the clearance chamber is provided on the top wall of the ice storage chamber 4.

[0037] A plurality of storage cavities 9 are formed in the storage part 2. The storage cavity 9 includes a large-diameter section in the middle and small-diameter sections at both ends of the large-diameter section, and the small-diameter sections communicate with the large-diameter section. The small-diameter section at the front end of the storage cavity 9 communicates with the outside, and the small-diameter section at the rear end of the storage cavity 9 communicates with the diffusion cavity 6.

[0038] A telescopic cylinder is arranged in each storage cavity 9, and the telescopic cylinder is coaxially arranged with the corresponding storage cavity 9. The telescopic cylinder is arranged in the large-diameter section of the storage cavity 9. The telescopic cylinder includes arc-shaped plates 12. There are a plurality of arc-shaped plates 12, and the plurality of arc-shaped plates 12 are circumferentially distributed along the axis of the storage cavity 9. The plurality of arc-shaped plates 12 are connected end to end in sequence, and an insertion plate 13 is connected between adjacent arc-shaped plates 12. The insertion plate 13 is slidably connected to the arc-shaped plate 12. Specifically, a rib plate 14 is fixedly connected to the arc-shaped plate 12, and the rib plate 14 and the insertion plate 13 are fixedly connected by an elastic cord 15. As Figure 9 shown, initially, under the action of the elastic cord 15, adjacent arc-shaped plates 12 are in contact, and at this time, the inner diameter of the telescopic cylinder is the smallest. In this embodiment, there are four arc-shaped plates 12.

[0039] A first limit block 11 is fixedly connected to the front end of each arc-shaped plate 12. A first limit hole 10 is formed at a position corresponding to the first limit block 11 on the inner wall of the front end of the large-diameter section. The first limit block 11 is slidably arranged in the first limit hole 10. The length direction of the first limit hole 10 is parallel to the radial direction of the storage cavity 9. When the first limit block 11 slides outward in the first limit hole 10, the arc-shaped plate 12 moves away from the axis of the storage cavity 9, and the inner diameter of the telescopic cylinder becomes larger.

[0040] A driving assembly for driving the inner diameter of the telescopic cylinder to become larger is arranged on the storage part 2. The driving assembly includes a first turntable 17 and a second turntable 18.

[0041] The first turntable 17 is rotatably installed at the front end of the storage cavity 9, and the second turntable 18 is rotatably installed at the rear end of the storage cavity 9. First inclined holes 19 are formed on both the first turntable 17 and the second turntable 18. The first turntable 17 and the second turntable 18 are both coaxially arranged with the telescopic cylinder. In this embodiment, four first inclined holes 19 are formed on both the first turntable 17 and the second turntable 18. The four first inclined holes 19 are circumferentially distributed according to the axis of the storage cavity 9. A first sliding column 16 is slidably arranged in each first inclined hole 19. The four first sliding columns 16 on the first turntable 17 are respectively connected to the four first limit blocks 11 at the front end of the telescopic cylinder, and the four first sliding columns 16 on the second turntable 18 are respectively connected to the rear ends of the four arc-shaped plates 12. When the first turntable 17 and the second turntable 18 rotate, under the guiding action of the first inclined hole 19, the first limit block 11 slides along the first limit hole 10.

[0042] A shielding assembly is provided at the front end of the storage cavity 9. The shielding assembly includes a plurality of baffles 22. The baffles 22 are fan-shaped, and the plurality of baffles 22 are circumferentially evenly distributed according to the axis of the storage cavity 9. The baffles 22 are slidably arranged at the front end of the storage cavity 9. Specifically, the baffle 22 is fixedly connected with a second limit block 23, and a second limit groove 24 is formed at a position corresponding to the second limit block 23 on the storage part 2. The second limit block 23 is slidably arranged in the second limit groove 24. The cross-section of the second limit block 23 is rectangular. The length direction of the second limit groove 24 is parallel to the radial direction of the storage cavity 9. The second limit block 23 slides along the second limit groove 24 towards the direction close to the axis of the storage cavity 9, thereby moving the baffle 22 towards the direction close to the axis of the storage cavity 9, and the plurality of baffles 22 contact each other and shield the front end of the storage cavity 9.

[0043] A plurality of second inclined holes 20 are formed in the first turntable 17, and the plurality of second inclined holes 20 correspond to the plurality of baffles 22 one by one. Each baffle 22 is connected with a second sliding column 21, and the second sliding column 21 is slidably arranged in the corresponding second inclined hole 20.

[0044] An accommodation cavity for accommodating the baffle 22 and the first turntable 17 is formed on the inner wall of the small-diameter section at the front end of the storage cavity 9.

[0045] A rotating shaft 32 is rotatably installed in the storage part 2. The front end of the rotating shaft 32 extends outside the storage part 2 and is fixedly connected with a knob 35. The front end of the rotating shaft 32 is coaxially and fixedly connected with a first worm 33, and the rear end of the storage part 2 is coaxially and fixedly connected with a second worm 34. The first worm 33 meshes with a first worm gear, and the first worm gear is fixedly sleeved on the outer circumference of the first turntable 17. The second worm 34 meshes with a second worm gear, and the second worm gear is fixedly sleeved on the outer circumference of the second turntable 18.

[0046] Turn the knob 35, the rotating shaft 32 rotates, the first worm 33 drives the first turntable 17 to rotate, the second worm 34 drives the second turntable 18 to rotate, thereby increasing the outer diameter of the telescopic cylinder and at the same time moving the baffle 22 towards the direction close to the axis of the storage cavity 9.

[0047] A plug block 28 is slidably arranged in each storage cavity 9. A plurality of protrusions 29 are fixedly arranged at intervals on the front end face of the plug block 28, and the plurality of protrusions 29 are circumferentially evenly distributed along the axis of the plug block 28. A communication groove 30 is formed on the plug block 28 between adjacent protrusions 29. A plurality of communication holes 31 are formed in the plug block 28. One end of the communication hole 31 is located on the circumferential surface of the plug block 28 and at the rear part of the plug block 28, and the other end of the communication hole 31 is located at the front end of the plug block 28 and communicates with the communication hole 31. The outer diameter of the plug block 28 is equal to the inner diameter of the small-diameter section of the storage cavity 9.

[0048] At the position corresponding to the rear part of the storage part 2 and the storage cavity 9, a push switch 25 is installed. The push switch 25 is fixedly connected to an electromagnet 26. A second spring 27 is sleeved on the electromagnet 26. One end of the second spring 27 is fixedly connected to the rear side wall of the storage part 2, and the other end of the second spring 27 is fixedly connected to the corresponding plug 28. The push switch 25 is connected to the control circuit of the electromagnet 26. Press the push switch 25 to energize the electromagnet 26, and press the push switch 25 again to cut off the power supply of the electromagnet 26.

[0049] Initially, under the action of the second spring 27, the plug 28 is at the front end of the storage cavity 9, and the plug 28 seals the front end of the storage cavity 9, preventing the cold air in the ice storage cavity 4 from flowing out through the storage cavity 9. When the plug 28 moves along the telescopic cylinder to the rear end of the storage cavity 9, the plug 28 squeezes the second spring 27, and the second spring 27 presses the push switch 25 to energize the second spring 27, and the second spring 27 adsorbs the plug 28, making the plug 28 at the rear end of the storage cavity 9.

[0050] The telescopic cylinder is used to place the medicine bottle 36. The front end of the medicine bottle 36 is provided with a bottle cap 38, and the outer diameter of the bottle cap 38 is adapted to the inner diameter of the small-diameter section at the front end of the storage cavity 9. The rear end of the medicine bottle 36 is connected with a base 37, and the base 37 is adapted to the plug 28.

[0051] Working principle: Initially, under the action of the second spring 27, the plug 28 is at the front end of the storage cavity 9. The second limit block 23 is at one end of the second limit groove 24 away from the axis of the storage cavity 9, and the baffle plates 22 are away from each other. The first limit block 11 is at one end of the first limit hole 10 close to the axis of the storage cavity 9, and the adjacent arc-shaped plates 12 are in contact with each other. At this time, the inner diameter of the telescopic cylinder is the smallest, and the inner diameter of the telescopic cylinder is equal to the outer diameter of the plug 28 at this time, and the plug 28 is in sealed sliding contact with the telescopic cylinder.

[0052] When in use, open the door 3, and then open the heat preservation cover 5, and put ice cubes into the ice storage cavity 4. Then cover the heat preservation cover 5.

[0053] Then, cooperate the base 37 at the rear end of the medicine bottle 36 to be conveyed with the plug 28, and then push the medicine bottle 36 inward. The plug 28 moves into the storage cavity 9, and the second spring 27 is gradually compressed.

[0054] When the plug 28 contacts the second spring 27, continue to push the medicine bottle 36, and the second spring 27 presses the push switch 25 to energize the second spring 27, and the second spring 27 adsorbs the plug 28, and then release the medicine bottle 36, and the medicine bottle 36 is in the storage cavity 9. At this time, the communication hole 31 is communicated with the diffusion cavity 6.

[0055] Turn the knob 35, the rotating shaft 32 rotates, the first worm 33 drives the first turntable 17 to rotate, and the second worm 34 drives the second turntable 18 to rotate. When the first turntable 17 and the second turntable 18 rotate, the first sliding column 16 moves along the first inclined hole 19 in a direction away from the axis of the storage cavity 9, the first limiting block 11 moves along the first limiting hole 10 in a direction away from the axis of the storage cavity 9, the arc-shaped plate 12 moves in a direction away from the axis of the storage cavity 9, the inner diameter of the telescopic cylinder becomes larger, and the gap between the inner wall of the telescopic cylinder and the medicine bottle 36 gradually increases. The telescopic cylinder communicates with the communication hole 31. The cold air in the diffusion cavity 6 enters the telescopic cylinder through the communication hole 31 and the communication groove 30, which is beneficial to making the medicine in the medicine bottle 36 receive cold evenly and is beneficial to improving the refrigeration effect on the medicine in the medicine bottle 36.

[0056] At the same time, when the first turntable 17 rotates, the second sliding column 21 moves along the second inclined hole 20 in a direction close to the axis of the storage cavity 9, the baffle 22 moves along the second limiting groove 24 in a direction close to the axis of the storage cavity 9, and the multiple baffles 22 move closer to the middle to block the front end of the storage cavity 9 to prevent the cold air in the telescopic cylinder from flowing out.

[0057] When the medicine bottle 36 moves into the telescopic cylinder, the air in the telescopic cylinder enters the diffusion cavity 6, increasing the air pressure in the diffusion cavity 6 and the ice storage cavity 4. As a result, the melting speed of the ice cubes in the ice storage cavity 4 accelerates, releasing more cold air. The more medicine bottles 36 are placed in the storage part 2, the higher the air pressure in the ice storage cavity 4 and the diffusion cavity 6, and the faster the ice cubes in the ice storage cavity 4 melt, releasing more cold air. This enables the medicine in the medicine bottle 36 to be in a suitable temperature environment, automatically adjusting the melting speed of the ice cubes according to the number of medicine bottles 36 placed, ensuring the refrigeration effect on the medicine in the medicine bottle 36 and avoiding waste of cold air or causing adverse effects on the medicine due to too low a temperature in the storage part 2.

[0058] When the pressure in the ice storage cavity 4 and the diffusion cavity 6 is too high, the sealing plate 7 moves upward, increasing the volume of the ice storage cavity 4, thereby avoiding difficulty in placing a new medicine bottle 36.

[0059] Then, close the door 3, drive the storage part 2 to move through the moving part 1, and deliver the medicine to the destination.

[0060] When the medicine bottle 36 needs to be taken, turn the knob 35, the rotating shaft 32 rotates, and the first turntable 17 and the second turntable 18 rotate. The second sliding column 21 slides along the second inclined hole 20 in a direction away from the axis of the storage cavity 9, and the baffle 22 moves away from the axis of the storage cavity 9, thereby releasing the limit on the medicine bottle 36. At the same time, the first sliding column 16 moves along the first inclined hole 19 in a direction close to the axis of the storage cavity 9, and the multiple arc-shaped plates 12 move closer to the middle and gradually return to the initial state.

[0061] Push the medicine bottle 36 inward to make the electromagnet 26 press the push switch 25 again, thereby cutting off the power supply of the electromagnet 26. Under the action of the second spring 27, the plug 28 has a tendency to move outward. Then, keep pressing the medicine bottle 36 by hand to make the medicine bottle 36 gradually move outward.

[0062] After taking out the medicine bottle 36, the plug 28 returns to its initial state. At this time, the communication hole 31 is blocked by the inner wall of the telescopic cylinder, and the plug 28 blocks the front end of the storage cavity 9 to prevent the cold air from flowing out. Moreover, the cold air in the diffusion cavity 6 can enter the telescopic cylinder at this time, playing a role in pre-cooling the telescopic cylinder.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
