[0006] And a fire extinguishing sleeve assembly, which is fixedly sleeved outside the temperature measuring sleeve assembly. The fire extinguishing sleeve assembly is sleeved outside the cable joint. The length of the fire extinguishing sleeve assembly is greater than the length of the temperature measuring sleeve assembly.

Detailed Implementation

[0019] Please see Figures 1-3A fire extinguishing sheath for a temperature-sensing monitoring cable connector, comprising:

[0020] A temperature-sensing sheath assembly 1, fitted over a cable connector, is used to monitor the temperature of the cable connector and is wirelessly connected to a wireless temperature-sensing host. The temperature-sensing sheath assembly 1 includes a power-collecting alloy plate 11, a temperature sensor 15, a guide post 16, a control box 17, a control chip 18, and a wireless communication device 19. The guide post 16 is hollow and fixed to the surface of the power-collecting alloy plate 11. The temperature sensor 15 is fixed to the inner wall of the power-collecting alloy plate 11. The control box 17 is inserted and fixed to the outer end of the guide post 16. The control chip 18 is fixedly installed inside the control box 17. The wireless communication device 19 is integrated onto the substrate of the control chip 18. The power-collecting alloy plate 11 is electrically connected to the control chip 18 through the guide post 16. The control chip 18 is connected to the temperature sensor 15 and the wireless communication device 19. The device 19 is connected to the wireless temperature measurement host. By looping the power-collecting alloy plate 11 around the outside of the cable joint, the power-collecting alloy plate 11 can collect power based on the electromagnetic induction phenomenon. The current is then supplied to the control chip 18 through the guide post 16. The hollow guide post 16 has a transmission line inside for connecting the control chip 18 and the temperature sensor 15. In this way, the temperature sensor 15 is close to the outer wall of the cable joint and can monitor the temperature of the cable joint. The temperature sensor 15 then transmits the monitored temperature information to the control chip 18. The control chip 18 controls the wireless communication device 19 to transmit the information to the wireless temperature measurement host, thereby realizing the function of real-time monitoring of the cable joint temperature. The wireless communication device 19 and the control chip 18 are located on the outside for easy maintenance.

[0021] And a fire extinguishing sleeve assembly 2, which is fixedly sleeved outside the temperature measuring sleeve assembly 1. The fire extinguishing sleeve assembly 2 is sleeved outside the cable joint, and its length is greater than that of the temperature measuring sleeve assembly 1. The fire extinguishing sleeve assembly 2 is used for automatic fire extinguishing of the cable joint. The fire extinguishing sleeve assembly 2 includes a fire extinguishing sleeve 21, a female hook and loop fastener 23, and a female hook and loop fastener 24. The inner wall of the fire extinguishing sleeve 21 is fixed to the outer wall of the power taking alloy plate 11. The outer end of the guide post 16 passes through the fire extinguishing sleeve 21. The control box 17 is tightly attached to the outer wall of the fire extinguishing sleeve 21. After the power taking alloy plate 11 is sleeved outside the cable joint, the fire extinguishing sleeve 21, which is fixed to its middle section, covers the cable joint and the adjacent electrical outlet. At the cable section, the fire-extinguishing sheath 21, 1-2m long, is used to wrap and protect the cable joint and cable over a large area. The power-taking alloy plate 11, only 10-20cm long, is located in the middle of the fire-extinguishing sheath 21 and is used to fix it at the cable joint for temperature measurement. In this way, if a fire breaks out at the cable joint, the fire-resistant fiber layer 212 can effectively block the spread of the internal fire source outward. At the same time, the flame-extinguishing microcapsules will rupture on their own when heated above 100°C, releasing the extinguishing agent. Therefore, the flame-extinguishing capsules are self-igniting fire extinguishers and do not need to rely on other devices for automatic fire extinguishing. The extinguishing agent is one or more of halon, heptafluoropropane, or perfluorohexanone. Thus, the flame-extinguishing layer 211 releases flame-extinguishing factors to quickly extinguish the fire when the cable joint catches fire, achieving dual safety protection.

[0022] A stud 12 is fixed to the outer surface of the first end of the power-taking alloy sheet 11. A positioning hole 14 is opened at the end of the power-taking alloy sheet 11. The end of the stud 12 is inserted into the positioning hole 14. A nut 13 is threadedly connected to the end of the stud 12. After the power-taking alloy sheet 11 is put on the outside of the cable connector, since the first and last ends of the power-taking alloy sheet 11 are not fixed to the first and last ends of the fire extinguishing sleeve 21, the power-taking alloy sheet 11 is only fixed to the middle section of the fire extinguishing sleeve 21. Therefore, when the power-taking alloy sheet 11 is wrapped around the outside of the cable, the stud 12 can pass through the positioning hole 14, which can limit the first and last ends of the power-taking alloy sheet 11.

[0023] The fire extinguishing sleeve 21 has positioning holes 22 at both its first and last ends. The end of the stud 12 is inserted into the positioning hole 22. The nut 13 is tightly attached to the outer surface of the end of the fire extinguishing sleeve 21. After limiting the first and last ends of the power taking alloy plate 11, the first end of the fire extinguishing sleeve 21 can be placed on the outer wall of the end of the power taking alloy plate 11. At the same time, the stud 12 is first passed through the positioning hole 22 at the first end of the fire extinguishing sleeve 21. Then the end of the fire extinguishing sleeve 21 is placed on the outer wall of the first end of the fire extinguishing sleeve 21. Then the stud 12 is passed through the positioning hole 22 at the end of the fire extinguishing sleeve 21. Finally, the nut 13 is turned until the stud 12 is tightly pressed against the end of the fire extinguishing sleeve 21. This completes the installation. This method is convenient to install and has strong stability after installation.

[0024] The sub-hook and loop fastener 23 is fixed to the outer surface of the first end of the fire extinguishing sleeve 21, and the female hook and loop fastener 24 is fixed to the inner surface of the last end of the fire extinguishing sleeve 21. The sub-hook and loop fastener 23 are connected. After the last end of the fire extinguishing sleeve 21 is placed on the outer wall of the first end of the fire extinguishing sleeve 21, the sub-hook and loop fastener 23 and the female hook and loop fastener 24 can be connected. This ensures that the first and last ends of the fire extinguishing sleeve 21 are pre-connected before the nut 13 is turned.
