[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a tank opening inspection device, comprising: a base plate 1; a supporting side plate 2 vertically fixed to the top of the base plate 1, a single-axis cylinder 7 and a double-axis cylinder 8 fixed to one side of the supporting side plate 2 for sealing the tank opening, a hollow sealing block 10 fixedly connected to the output end of the double-axis cylinder 8, a connecting hole being provided at the bottom of the sealing block 10, one end of the sealing block 10 being connected to a pressure detection box 11 fixed to one side of the supporting side plate 2 via an air duct, a pressure sensor being embedded inside the pressure detection box 11; an air pump 4 placed above the base plate 1, a gas flow meter 5 fixedly connected to the output end of the air pump 4, an inflation nozzle 21 fixedly connected to the output end of the gas flow meter 5 via a one-way valve, a U-shaped frame 22 slidably mounted on one end of the inflation nozzle 21 for driving the tank connector to dock and separate from the inflation nozzle 21.

[0023] It should be noted that this embodiment includes a controller, a timer, and corresponding control buttons. The humidification tank is placed on top of the base plate 1, and the connector of the connecting pipe in the middle of the humidification tank is placed inside the U-shaped frame 22. The U-shaped frame 22 slides to connect the connector with the inflation nozzle 21. The dual-axis cylinder 8 and the single-axis cylinder 7 drive the corresponding sealing block to seal the humidification tank. The sealing block 10 is connected to the humidification tank. The air pump 4 inflates the humidification tank through the gas flow meter 5 and the inflation nozzle 21. Under the guidance of the sealing block 10, the pressure sensor can detect the pressure inside the positioning plate 12. When the air pump inflates, the air pressure inside the humidification tank will gradually increase. When the air pressure reaches the set standard value or threshold, the controller controls the air pump to stop inflating. The gas flow rate is obtained from the cumulative flow data of the flow meter. Combined with the actual volume and pressure value of the humidification tank, the actual ventilation rate is calculated. The calculated actual ventilation rate is compared with the designed ventilation rate of the humidification tank. If the two are consistent, it means that the air flow of the humidification tank meets the standard; if the deviation is large, it means that there are problems such as poor airflow or leakage in the humidification tank. When the deviation is large, the audible and visual alarm light on the outside of the control box 3 will sound an alarm. When the inspection is over, the connector and the air inlet 21 are separated by the U-shaped frame 22, and the single-axis cylinder 7 and the double-axis cylinder 8 are reset. Then the workpiece is removed.

[0024] In one embodiment, a positioning plate 12 is fixedly connected to the top of the base plate 1 and below the single-axis cylinder 7 and the dual-axis cylinder 8. A sealing pressure block 9 is fixedly connected to the output end of the single-axis cylinder 7. A support frame 13 is fixedly connected to one side of the base plate 1 and at the position corresponding to the positioning plate 12. A wire harness notch 14 is fixedly connected to the top of the support frame 13.

[0025] It should be noted that in this embodiment, the positioning plate 12 is used to position the humidification tank. The bottom of the humidification tank is placed inside the positioning plate 12, and the end of the support frame 13 blocks the part of the protruding opening at the top of the humidification tank, thereby positioning the humidification tank. The part of the protruding opening at the top corresponds to the position of the sealing block 9 and the sealing block 10. Then, the top of the humidification tank and the conduit are placed inside the wire notch 14 to limit the conduit. The single-axis cylinder 7 drives the sealing block 9 and the double-axis cylinder 8 drives the sealing block 10 to seal the bottom of the humidification tank, thereby making the humidification tank and the pressure detection box 11 form a closed connected space.

[0026] In one embodiment, a telescopic electromagnet 15 is fixedly connected to one side of the support frame 13, and a push plate 16 is fixedly connected to the telescopic end of the telescopic electromagnet 15. A marking stamp 17 is laterally slidably connected to one side of the push plate 16, and a spring 18 is fixedly connected between the marking stamp 17 and the push plate 16. A control box 3 is fixedly connected to the top of the base plate 1, and the air pump 4 and the gas flow meter 5 are both fixedly connected to one side of the control box 3.

[0027] It should be noted that, in this embodiment, when a defect is detected, the controller controls the telescopic electromagnet 15 to move the push plate 16 laterally. A sliding rod, slidably connected to the support frame 13, is fixed to one side of the push plate 16. The telescopic electromagnet 15 moves forward via the marking stamp 17 on the push plate 16. One side of the marking stamp 17 is slidably connected to the push plate 16 via a metal rod, and a spring 18 is sleeved on the outside of the metal rod. The spring 18 is compressed, causing the marking stamp 17 to make adaptive contact with the humidification tank. After contact with the outside of the humidification tank, the marking stamp 17 marks the outside of the humidification tank. Under the action of a timer, the controller controls the telescopic electromagnet 15 to reset, causing the marking stamp 17 to separate from the humidification tank.

[0028] In one embodiment, a support base 23 is fixedly connected to the top of the base plate 1, an air inlet 21 is fixedly connected to one end of the support base 23, a single-axis cylinder 20 is fixedly connected to one side of the support base 23, a U-shaped frame 22 is fixedly connected to the output end of the single-axis cylinder 20, the U-shaped frame 22 is slidably connected to the support base 23, and a limit groove 6 is formed on the top of the U-shaped frame 22 along its length direction.

[0029] It should be noted that in this embodiment, the connector of the humidification tank is a plastic tube with a circular limiting piece fixed to the outside. The limiting piece is placed inside the limiting groove 6, and the plastic tube is placed in the middle of the U-shaped frame 22 to limit the connector. The U-shaped frame 22 is driven to slide on the top of the support seat 23 by the single-axis cylinder 20, so as to connect and separate the connector and the air nozzle 21, avoiding manual insertion and removal.
