[0017] In order to make the utility model purposes, technical scheme and advantages more clearly, in the following, the utility model is further detailed with the drawings and examples, but the example is not as the limitation of the utility model.

[0018] As Figs. 1 to 4 The utility model discloses an embodiment, including support frame 1, X axle system 2, support positioning mechanism and detection water tank system 3, X axle system 2 sets up at the top of support frame 1, and detection water tank system 3 sets up on X axle system 2, and support positioning mechanism includes front support positioning wheel 4 and rear support positioning wheel 6, and front support positioning wheel 4 sets up at the front end of support frame 1, and rear support positioning wheel 6 sets up at the rear end of support frame 1.

[0019] In the embodiment, support frame 1 is composed of a support frame and a protection plate, and the support frame is fixed on the ground to stabilize the equipment, and the protection plate serves to protect parts and is aesthetically pleasing.

[0020] In the embodiment, X axle system 2 is composed of a motor, a ball screw, a linear guide rail and an organ protection cover, and the motor drives the ball screw to rotate, so that the detection water tank moves left and right on the linear guide rail, and the detection water tank has five positions on the X axis, which are an idle position and four detection positions of the thick-walled copper pipes 5.

[0021] In the embodiment, front support positioning wheel 4 is composed of a front V-shaped wheel, a front fixed seat, a front bearing and a front support shaft, and the front support positioning wheel 4 is installed on the detection water tank mounting plate to align the thick-walled copper pipes 5 with the equipment inlet.

[0022] In the embodiment, rear support positioning wheel 6 is composed of a rear V-shaped wheel, a rear fixed seat, a rear bearing and a rear support shaft, and the rear support positioning wheel 6 is installed on the detection water tank mounting plate to align the thick-walled copper pipes 5 with the equipment inlet.

[0023] In this embodiment, the detection water tank system 3 is composed of the detection water tank 12, the water receiving tank, the water blocking device, the rotary flaw detection device 18, the follow-up thickness measuring device, the rotary motor 16 and its transmission mechanism 19, and the back blowing device 15. The rotary flaw detection device 18 can reciprocate within a range of 100°, and the probes are evenly distributed in four groups on the probe box 17 according to fixed incident angles. The follow-up thickness measuring device is composed of support wheels, a probe box, guide rods, compression springs, and a fixed seat. Since the support wheels can be extended and retracted due to the springs inside, and the four groups of support wheels are evenly distributed on the circumference of the probe box 17, the thick-walled copper pipe 5 is always at the center of the probe box 17, ensuring the accuracy of the thickness data measured by the probes. The water blocking device is composed of two to three layers of wear-resistant rubber plates. The inner hole of the rubber plate is slightly smaller than the diameter of the copper pipe, ensuring that the detection water tank does not leak water. The back blowing device at the rear is responsible for blowing away the water stains on the surface of the copper pipe. The liquid level detection device can feedback the water level in the detection water tank. When the water level is lower than the lower liquid level setting value, water replenishment begins to ensure that the water level during the detection process does not fall below the lower liquid level setting value. When the thick-walled copper pipe 5 is detected, the two water release valves are opened at the same time to quickly drain the water in the tank, preventing water from entering the thick-walled copper pipe 5.

[0024] The water receiving tank includes a front water receiving tank 10 and a rear water receiving tank 11. The right end of the detection water tank 12 is connected to the front water receiving tank 10, and the left end of the detection water tank 12 is connected to the rear water receiving tank 11. The water blocking device includes an inlet water blocking device 13 and an outlet water blocking device 14. The inlet water blocking device 13 is arranged on the front water receiving tank 10, and the outlet water blocking device 14 and the back blowing device 15 are arranged on the rear water receiving tank 11.

[0025] In this embodiment, the water circulation system 7 is composed of the water receiving tank 9, the main water pump, the water replenishment pump, the filter, the electromagnetic valve, and the pipeline. When the thick-walled copper pipe 5 completely passes through the detection equipment, the main water pump and the water replenishment pump are started at the same time to quickly inject water into the detection water tank. When the water level in the detection water tank reaches the high liquid level set by the liquid level detection device, the water inlet electromagnetic valve is closed, and the backflow electromagnetic valve is opened, causing the water to flow back to the water storage tank 8. During the detection process, the liquid level gradually decreases, and the leaked water flows back to the water storage tank 8 through the pipeline after being filtered by the water receiving tank. When the liquid level reaches the low liquid level set by the liquid level detection device, the water replenishment pump starts to inject water into the detection water tank. When the water level reaches the high liquid level, the water replenishment pump stops. This process is repeated until the detection of the thick-walled copper pipe 5 is completed.

[0026] In this embodiment, the movement process is described as follows:

[0027] 1. Initial position of the equipment: the detection equipment is in an idle position.

[0028] 2. Movement process:

[0029] 2.1. When the last batch of thick-walled copper pipes 5 is cut by the saw, and the new thick-walled copper pipe 5 has not been transported to the detection position, the detection water tank is moved to the position of the thick-walled copper pipe 5 to be detected.

[0030] 2.2, after the thick-walled copper pipe 5 passes through the support positioning wheel and passes through the detection water tank, the main water pump 22 and the water supplementing pump 23 are started simultaneously to quickly inject water into the detection water tank, when the water level in the detection water tank reaches the high liquid level set by the liquid level detection device 20, the thick-walled copper pipe 5 starts to be detected; at the same time, the water inlet electromagnetic valve 21 is closed and the backflow electromagnetic valve is opened, so that the water flows back to the water storage tank 8, after a certain interval, the main water pump 22 is closed, and during the detection process, the liquid level gradually decreases, the missed water flows back to the water storage tank 8 through the water tank and pipeline filtering, when the liquid level reaches the low liquid level set by the liquid level detection device, the water supplementing pump 23 is started to inject water into the detection water tank, and when the high liquid level is reached, the water supplementing pump 23 is stopped, and the process is repeated until the detection of the thick-walled copper pipe 5 is completed.

[0031] 2.3, when the front-end sensor of the detection equipment cannot detect the thick-walled copper pipe 5, the two water discharge valves of the detection water tank are opened to quickly drain the water in the detection water tank.

[0032] 2.4, when the thick-walled copper pipe 5 completely passes through the detection water tank, the detection water tank is moved to an idle position or to the position of the thick-walled copper pipe 5 to be detected, and the next thick-walled copper pipe 5 is detected.
