[0020] To further understand the content of the present utility model, the utility model will be described in detail with reference to the accompanying drawings.

[0021] Embodiment 1

[0022] The intelligent hydraulic safety coupling of this embodiment, as Figure 1 、 2 shown, includes a coupling body 1, an oil cavity 6 inside the coupling body 1, and a shearing ring 5 sleeved on the outer circular surface of the coupling body 1, and also includes a wireless pressure sensor 2; multiple planes and fixing holes 11 are also machined on the outer circular surface of the coupling body 1, the fixing holes 11 communicate with the oil cavity 6, the wireless pressure sensor 2 is fixed in one of the fixing holes 11, the probe of the wireless pressure sensor 2 extends into the oil cavity 6, and the wireless pressure sensor 2 transmits the monitored abnormal signal to the Internet monitoring device. The fixing hole 11 is preferably a threaded hole for convenient disassembly, and a sealing gasket is arranged at the threaded part.

[0023] The wireless pressure sensor 2 is powered by a built-in lithium battery, configured with a pressure sensing core, a microprocessor, and a sensor signal conditioning circuit, and adopts a wireless communication network to realize the wireless transmission of monitored pressure data to the cloud, and the software on the Internet device can obtain the measurement data.

[0024] During the operation of the hydraulic safety coupling, if there are problems with the seals of each threaded port communicating with the oil cavity 6, resulting in a decrease in the oil cavity pressure, a decrease in the protection torque, and an unsafe transmission of the working equipment, the software can immediately issue a warning signal or directly issue a shutdown command according to the change in the pressure value and the set relevant alarm thresholds, and timely handle the problematic hydraulic safety coupling, which is both efficient and safe, and can be maintained with low cost.

[0025] Embodiment 2

[0026] The intelligent hydraulic safety coupling of this embodiment has the same basic structure as that of Embodiment 1, and the differences or improvements are as follows: As Figure 1 、 3As shown in the figure, it further includes a shearing monitoring device 3 and a shearing pipe assembly 4. The shearing pipe assembly 4 has two or more symmetrical parts. The shearing monitoring device 3 includes a circuit module 31, a first terminal 32, a second terminal 33, and a wireless signal transmitting module 34. One end of both the first terminal 32 and the second terminal 33 is connected to the connecting circuit module 31, and the other ends are respectively connected to the outer cylindrical surface of the coupling body 1 and the head of the shearing pipe assembly 4. The wireless signal transmitting module 34 is also connected to the circuit module 31. The shearing monitoring device 3 and the coupling body 1 form a closed electrical circuit, and the electrical circuit switch signal is transmitted by the wireless signal transmitting module 34 to the Internet monitoring device. The circuit module 31 and the wireless signal transmitting module 34 are fixed in the module box 30, and the module box 30 is fixed on the plane machined on the outer cylindrical surface of the coupling body 1, which protects each module and is convenient for disassembly. A sealing washer is fixed at the connection between the wireless pressure sensor 2 and the fixing hole 11 to avoid oil leakage.

[0027] The shearing pipe assembly 4 is installed in the hydraulic safety coupling body 1. There is a processed internal thread 41 hole at its head, and the second terminal 33 is connected to the shearing pipe assembly 4 by means of screw pressing. A plane and a threaded hole 11 are machined on the outer cylindrical surface of the hydraulic safety coupling body 1, and the first terminal 32 is also connected to the hydraulic safety coupling body 1 by means of screw pressing. In this way, the hydraulic safety coupling 1, the shearing monitoring device 3, and the shearing pipe assembly 4 form a closed electrical circuit, and the switch signal is transmitted by the wireless signal transmitting module 34 to the Internet device. When the hydraulic safety coupling works and overload protection occurs, the head of the shearing pipe assembly 4 is cut off by the cutting ring 5, the second terminal 33 is separated, the original closed electrical circuit is disconnected, and the emitted switch signal is transmitted by the wireless signal transmitting module 34 to the Internet device.
