[0021] Example 1, as Figure 1As shown, this utility model provides a fault-prevention detection device for drilling blockages, comprising: a gas source device 1 for outputting gas, wherein the gas source device 1 is fixedly connected to a pressure gauge 3 and a sealing plate 4 via a three-way pipe 2, wherein the first end of the three-way pipe 2 is fixedly and sealed to the gas outlet of the gas source device 1, the second end of the three-way pipe 2 is fixedly and sealed to the pressure gauge, and the third end of the three-way pipe 2 is fixedly and sealed to the sealing plate 4, wherein the sealing plate 4 is provided with an exhaust port 401, and a sealing gasket 402 is fixedly provided on the sealing plate 4 surrounding the exhaust port 401.

[0022] In this embodiment, the sealing plate 4 is pressed onto the workpiece 5 to be tested, so that the exhaust port 401 corresponds to the test hole 501 on the workpiece 5. The hole is sealed by the sealing gasket 402. Then, the air source device 1 is turned on, allowing gas to be injected into the test hole 501 through the three-way pipe 2. The pressure change of the pressure gauge 3 is monitored. If the pressure remains unchanged, it indicates that the gas can pass smoothly, and the hole is determined to be drilled through. If the pressure rises, the hole is determined to be not fully drilled. The diameter of the exhaust port 401 is smaller than the diameter of the test hole 501.

[0023] This solution employs pneumatic detection to avoid human error and improve detection accuracy. It can be integrated into the production line for automated detection, increasing production efficiency. It is also low-cost, suitable for rapid detection of mass-produced workpieces, and highly convenient. Simply press the sealing plate 4 onto the workpiece 5 to be tested. For single workpieces, manual pressing can be used; for batch testing of multiple workpieces, a drive mechanism for outputting linear motion can be used. The output end of the drive mechanism is fixedly connected to the end of the sealing plate 4 furthest from the workpiece 5, causing the drive mechanism to move the sealing plate 4 closer to the workpiece 5. The drive mechanism includes, but is not limited to, conventional technologies in the field such as pneumatic cylinders, hydraulic cylinders, and electric cylinders.

[0024] The three-way pipe 2 is threadedly sealed to the gas source device 1, pressure gauge 3, and sealing plate 4 to facilitate installation and disassembly.

[0025] Example 2, as Figure 2-3As shown, this utility model provides a fault-prevention detection device for borehole blockage, comprising: a gas source device 1 for outputting gas, wherein the gas source device 1 is fixedly connected to a pressure gauge 3 and a sealing plate 4 via a three-way pipe 2, wherein the first end of the three-way pipe 2 is fixedly and sealed to the outlet of the gas source device 1, the second end of the three-way pipe 2 is fixedly and sealed to the pressure gauge, and the third end of the three-way pipe 2 is fixedly and sealed to the sealing plate 4, wherein the sealing plate 4 is provided with an exhaust port 401, and a sealing gasket 402 is fixedly provided around the exhaust port 401 on the sealing plate 4; wherein the sealing plate 4 is provided with an exhaust pipe, the exhaust pipe is provided with an exhaust port 401 communicating with the three-way pipe 2, a sealing block 403 is slidably connected to the exhaust pipe and sleeved on the exhaust pipe, the sealing block 403 is sleeved with the sealing gasket 402, and an elastic element 404 is fixedly connected between the sealing block 403 and the sealing plate 4 on the side of the sealing block 403 near the sealing plate 4, the elastic element 404 including but not limited to a spring and an elastic pad.

[0026] In this embodiment, the operation method is the same as in Embodiment 1. The difference is that in this embodiment, the sealing gasket 402 is fixedly set on the sealing block 403. When the sealing plate 4 is pressed on the workpiece 5 to be tested, the sealing block 403 is made to fit more tightly with the workpiece 5 to be tested through the action of the elastic element 404, so as to improve the sealing effect.

[0027] The sealing block 403 is frustum-shaped and has an axially arranged through hole that mates with the exhaust pipe, which is slidably connected within the through hole. This design sets the sealing block 403 in a frustum shape, with its short-diameter end abutting against the test hole 501. This facilitates the positioning of the exhaust pipe and the test hole 501, adapts to test holes 501 of different diameters, increasing its applicability, and ensures that the sealing gasket 402 abuts against the inner wall of the test hole 501, improving the sealing effect.

[0028] The sealing plate 4 has a groove 405, and the exhaust pipe is coaxially arranged with the groove 405. The long-diameter end of the sealing block 403 is provided with a slide 406 that is fixedly connected to the sealing block 403. The slide 406 is keyed to the groove 405. This solution, by setting the slide 406 to cooperate with the groove 405, firstly ensures the stability of the sliding of the sealing block 403; secondly, by setting the slide 406 and ensuring that the sealing gasket 402 is only fitted on the sealing block 403, the sliding friction between the slide 406 and the groove 405 is reduced.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
