Specific embodiments

[0015] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0016] Refer to Figures 1-5, A rapid connection device for a temperature sensor probe, comprising a base 1 for a temperature sensor 3 and different types of probes. A support plate 2 is fixed on the upper side wall of the base 1. A rotating plate 5 driven by a motor 4 to rotate is arranged on the support plate 2. A probe assembly is arranged on the rotating plate 5. The probe assembly includes a plurality of mounting plates 6 connected at intervals. A wire reel 7 is arranged on the mounting plate 6. A circuit 18 is wound on the wire reel 7. The probe is installed at the end of the circuit 18. A chute is formed on the mounting plate 6. The other end of the circuit 18 is connected to a waterproof plate 17 sliding in the chute. Limiting grooves 20 are formed on the inner walls of both sides of the chute. Counterweight rolling shafts 21 rolling in the limiting grooves 20 are installed on the outer walls of both sides of the waterproof plate 17. The counterweight rolling shafts 21 can roll in the limiting grooves 20 to move the waterproof plate 17. A waterproof groove 22 is formed on the waterproof plate 17. A plug 19 connected to the circuit 18 is arranged in the waterproof groove 22. An arc-shaped connecting plate 24 is fixed on the outer wall of the base 1 through a support rod. A connecting cylinder 25 is arranged on the arc-shaped connecting plate 24. An interface 32 connected to the temperature sensor 3 through a wire 26 is arranged in the connecting cylinder 25; A guiding groove 8 is fixed on the outer wall of one side of the probe assembly. A U-shaped plate 9 with its end inserted into the guiding groove 8 is fixedly connected to the outer wall of the rotating plate 5. A fixing plate 10 is fixed on the outer wall of the other side of the probe assembly. An electric push rod 11 is fixed on the lower side wall of the rotating plate 5. The driving end of the electric push rod 11 is fixedly connected to the outer wall of the fixing plate 10. The guiding groove 8 plays a guiding role when the probe assembly moves, avoiding the deviation of the position of the probe assembly. The driving end of the electric push rod 11 expands and contracts to drive the fixing plate 10 and the probe assembly to move, realizing the adjustment of the positions of multiple mounting plates 6. The types of probes on different mounting plates 6 are different. According to needs, the mounting plate 6 carrying the required probe is moved to a position corresponding to the opening 12. Then the rotating plate 5 rotates and tilts until the position of the waterproof plate 17 corresponds to that of the connecting cylinder 25. The waterproof plate 17 connected to the probe can slide down along the chute until the waterproof plate 17 is inserted into the connecting cylinder 25, and the plug 19 is inserted into the interface 32, realizing the preliminary connection between the temperature sensor 3 and the probe.

[0017] The inner wall specifications of the waterproof plate 17 and the connecting cylinder 25 are the same. The end of the rotating plate 5 rotates while fitting the outer wall of the arc-shaped connecting plate 24. When the rotating plate 5 rotates to be inclined and the waterproof plate 17 is aligned with the connecting cylinder 25, the waterproof plate 17 slides along the chute until its end is inserted into the connecting cylinder 25. An inserting and removing mechanism for inserting and connecting the plug 19 and the interface 32 is also arranged on the rotating plate 5.

[0018] The insertion and removal mechanism includes a slot 12 opened at the end of the rotating plate 5. A groove communicating with the slot 12 is opened on the lower side wall of the rotating plate 5. Extension slots are opened on the inner walls on both sides of the slot 12. A telescopic component is fixed in the extension slots. An electric push rod II 15 is fixed in the groove. A right-angle plate 16 is fixedly connected between the outer wall of the driving end of the electric push rod II 15 and the telescopic component. The telescopic component includes a connection box 13. An electromagnet is fixed in the connection box 13. A plug rod 14 is slidably inserted at the end of the connection box 13. A magnet plate is fixed at one end of the plug rod 14 located inside the connection box 13. A telescopic spring is fixedly connected between the magnet plate and the inner wall of the connection box 13. A slot 23 is opened at the end of the counterweight rolling shaft 21. After the waterproof plate 17 is inserted into the connection cylinder 25, under the action of the friction force between the plug 19 and the interface 32, the plug 19 cannot be inserted to a deeper depth. At this time, the plug rod 14 is located corresponding to the position of the slot 23. The electromagnet is powered on. Under the repulsive force between the electromagnet and the magnet plate, the magnet plate and the plug rod 14 are pushed to move inward. The end of the plug rod 14 is inserted into the slot 23. The electric push rod II 15 is started to drive the right-angle plate 16, the connection box 13 and the waterproof plate 17 to move forward, so that the end of the plug 19 continues to be inserted into the interface 32, realizing the connection between the probe and the temperature sensor 3. When disconnecting the plug 19 from the interface 32 subsequently, the driving end of the electric push rod II 15 retracts, pulling the plug 19 out of the interface 32. The waterproof plate 17 moves into the slot 12. The electromagnet is powered off, and the plug rod 14 disengages from the slot 23. The rotating plate 5 is driven by the motor 4 to rotate to the horizontal or tilt to the left, and the wire reel 7 automatically winds up the wire 18, and the waterproof plate 17 returns to its original position; Further, the diameter of the plug rod 14 is smaller than the inner diameter of the slot 23, ensuring that the plug rod 14 can be inserted into the slot 23 after the waterproof plate 17 moves. Then, through the movement of the connection box 13, the outer wall of the plug rod 14 can be in contact with the inner wall of the slot 23, and the connection box 13 can continue to move to drive the waterproof plate 17 to move synchronously; Further, the wire reel 7 adopts a mechanical spring type automatic wire winding. When the rotating plate 5 tilts to the right, by virtue of the gravity of the counterweight rolling shaft 21 and the waterproof plate 17 itself, overcoming the elastic force of the spring, the waterproof plate 17 slides downward. When the rotating plate 5 tilts to the left or rotates to the horizontal, under the reverse acting force of the spring, the wire 18 is wound up.

[0019] The temperature sensor 3 is provided with multiple continuous water pipes. A water tank 31 is arranged on the temperature sensor 3. A water pump connected to the end of the water pipe is arranged in the water tank 31. Two arc-shaped pipes 27 are fixed on the outer wall of the temperature sensor 3. One end of one arc-shaped pipe 27 is connected to the other end of the water pipe, and the end of the other arc-shaped pipe 27 communicates with the water tank 31. Extension pipes 28 are connected to the ends of both arc-shaped pipes 27. The two extension pipes 28 are communicated through a connecting pipe 29. Openings are formed on the outer walls of the two extension pipes 28, and a water bladder layer 30 is fixed in the openings. After the plug 19 is inserted into the interface 32, the waterproof plate 17 is located between the two extension pipes 28. During the use of the temperature sensor 3, the water pump is started to pump the water in the water tank 31 into the arc-shaped pipes 27, the extension pipes 28 and the water pipes for flowing. The water pipes absorb the heat in the temperature sensor 3. The flowing water in the water pipes can absorb and carry away the heat on the water pipes, so that the water pipes can continuously absorb heat. When the water flows into the extension pipes 28, the water bladder layer 30 expands outward under the impact of water pressure and contacts the outer wall of the waterproof plate 17. On the one hand, it can press against the waterproof plate 17, increasing the stability of the connection between the waterproof plate 17 and the connecting cylinder 25. On the other hand, it can also absorb the heat on the waterproof plate 17 (heat is generated at the connection between the plug 19 and the interface 32 due to high contact resistance and current flow).

[0020] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
