[0025] like Figures 1 to 5 As shown, a specific embodiment of the utility model provides a sintered filter cartridge filter pore detection device that can be conveniently clamped, including an operating table 1, on which a left side plate 2 and a right side plate 3 are provided, and a filter cartridge 4 for detection is provided on the top of the operating table 1; both ends of the filter cartridge 4 are provided with fixing components for clamping the filter cartridge 4 and maintaining sealing. By setting the fixing components, the filter cartridge 4 for pore detection can be fixed, and its two ends can be kept in a relatively sealed state to prevent the solution from entering its interior and affecting the detection during the detection process. The fixing components include clamping blocks 5 provided at both ends of the filter cartridge 4, and the clamping blocks 5 are provided with gaskets 6, pads 7 and annular airbags 8, and the annular airbags 8 are fixedly connected with an inflation tube 9; and also include a clamping block 5 provided between the left side plate 2 and the right side plate 3 for the filter cartridge 4 A mobile detection component for performing pore detection can automatically move the fixed filter cartridge 4 into the solution for immersion by setting the mobile detection component, thereby achieving the detection purpose, so that the entire device can be fixed and at the same time has the function of moving the filter cartridge 4 into the solution for immersion. The mobile detection component includes a main telescopic rod 10 installed on the operating table 1, a pipeline is connected to the main telescopic rod 10, and a secondary telescopic rod 11 is connected to the other end of the pipeline. A frame 12 and a bent plate 121 are fixedly connected to the clamp block 5, and the frame 12 is slidably connected to the bent plate 121. Hydraulic oil is provided in the main telescopic rod 10 and the secondary telescopic rod 11, and is connected by a pipeline, so that when pressure is applied to one of them to make it contract, the hydraulic oil inside flows to the other to push the other to achieve an elongation effect.

[0026] like Figures 1 to 5As shown, specifically, when the filter cartridge 4 is inspected, the clamp block 5 is fixedly connected with an arc plate 15, and the arc inner diameter of the arc plate 15 is adapted to the two ends of the filter cartridge 4, and it is placed on the arc plate 15 on the clamp block 5, so that the filter cartridge 4 can be kept concentric with the inner cavity of the clamp block 5, and a slide rail and a motor 16 are fixedly installed on the operating table 1, and the right side plate 3 is slidably connected to the slide rail, and a threaded rod 17 is fixedly connected to the output shaft of the motor 16, and the threaded rod 17 is threadedly connected to the right side plate 3. After the filter cartridge 4 is placed, start The motor 16 drives the threaded rod 17 to rotate, so that the right side plate 3 moves toward the middle along the slide rail. During the movement, the right side plate 3 pushes the right clamping block 5 to gradually move toward the middle through the bent plate 121. At this time, the movement of the bent plate 121 causes the frame 12 to slide on the bent plate 121, and the clamping block 5 gradually pushes the filter cartridge 4 to move so that the filter cartridge 4 gradually enters the inner cavity of the two clamping blocks 5. The setting of the arc plate 15 enables the filter cartridge 4 to remain concentric with the inner cavity of the clamping block 5 during the process of entering the clamping block 5, thereby facilitating the filter cartridge 4 to move. The frame 12 slides on the bent plate 121 and fits with the right side plate 3, so that the right side plate 3 pushes the frame 12 and the bent plate 121 to move at the same time. The frame 12 is fixedly connected with a telescopic rod 23, and the telescopic rod 23 is fixedly connected with a movable block 24. A spring 25 is fixedly connected between the movable block 24 and the frame 12. As the right side plate 3 pushes the frame 12 to move, the frame 12 pushes the telescopic rod 23 and the spring 25. Applying pressure causes it to contract and generate a reaction force. The reaction force generated by the spring 25 acts on the frame 12, so that the frame 12 pushes the clamping block 5 on the left and the clamping block 5 on the right to clamp and fix the filter cartridge 4 in the middle, and the gasket 6 and the pad 7 can be used as sealing pads to enhance the sealing of the filter cartridge 4 in the clamping block 5. At the same time, the gas generated by the external gas supply device enters the annular airbag 8 through the inflation pipe 9, so that it is inflated and expands to fit tightly against the filter cartridge 4, thereby further enhancing the sealing of the filter cartridge 4 in the clamping block 5.

[0027] like Figures 1 to 5As shown, specifically, a moving block 20 is fixedly connected to the bottom end of the secondary telescopic rod 11, and a tension spring 21 is fixedly connected between the moving block 20 and the fixed frame 19, a limiting groove 22 is provided on the frame 12, and the moving block 20 is slidably connected in the limiting groove 22. When the right side plate 3 moves to a position where the frame 12 can be pushed to move, the right side plate 3 fits against the main telescopic rod 10 and applies pressure thereto, the main telescopic rod 10 is forced to contract, and the hydraulic oil inside the main telescopic rod 10 is used as a medium to enter the secondary telescopic rod 11 through a pipeline to push the secondary telescopic rod 11 to extend, so that the extension of the secondary telescopic rod 11 pushes the frame 12 downward by pushing the moving block 20 at the bottom, and the tension spring 21 is forced to extend to generate a reaction force, at this time, the frame 12 is achieved to move to the left. The movable block 20 slides in the limiting groove 22 while moving. The frame 12 is fixedly connected with a telescopic rod 23, and a movable block 24 is fixedly connected with the telescopic rod 23. A spring 25 is fixedly connected between the movable block 24 and the frame 12. Guide grooves 26 are provided on the left side plate 2 and the right side plate 3, and the movable block 24 and the bent plate 121 are slidably connected in the guide grooves 26. The limiting grooves 22 and the guide grooves 26 are both T-shaped, and the frame 12 moves downward to push the bent plate 121, the telescopic rod 23 and the movable block 24 to move downward. The bent plate 121 and the movable block 24 move downward in the guide groove 26. At this time, the clamping block 5 carries the clamped filter cartridge 4 to move downward, so that the filter cartridge 4 moves closer to the left side plate 2. At the same time, it moves downward, a solution box 18 is fixedly installed on the operating table 1, and the filter cartridge 4 gradually enters the solution box 18 for immersion. An air supply pipe 13 is slidably connected to the clamp block 5, and an air pressure sensor 14 is fixedly installed on the air supply pipe 13. During the immersion process, air is supplied to the air supply pipe 13 through an external air supply device to generate gas in the filter cartridge 4 until the solution produces bubbles, thereby achieving the purpose of detection. After the detection is completed, the motor 16 is driven in the reverse direction, so that the right side plate 3 moves in the reverse direction and resets. During the resetting process of the right side plate 3, the movable bending plate 121 is driven to move, and the reaction force of the spring 25 pushes the frame 12 to move and reset, and the right side plate 3 gradually separates from the main telescopic rod 10, so that the auxiliary telescopic rod 11 is under the reaction of the tension spring 21. Pull the moving block 20 downward with force to retract it, and the contraction of the secondary telescopic rod 11 can push the hydraulic oil into the main telescopic rod 10 in the opposite direction, so that the main telescopic rod 10 extends and resets. When the secondary telescopic rod 11 pulls the moving block 20, it pulls the frame 12 upward, thereby pulling the clamping block 5 and the filter cartridge 4 upward out of the solution tank 18 for reset. The right side plate 3 gradually resets and drives the bent plate 121 to move, so that the clamping block 5 and the filter cartridge 4 are gradually separated. After the filter cartridge 4 is separated from the clamping block 5, it can be removed. The effect achieved during the entire reset process is that the filter cartridge 4 moves toward the right side plate 3 while moving upward out of the solution tank 18, and during the movement toward the right side plate 3, the clamping block 5 can be separated from the filter cartridge 4, so that the filter cartridge 4 is easily removed.
