[0002] Container liquid bag is a new type of liquid transportation method. It can convert a 20-foot standard container into a transport container that can carry a large amount of bulk liquid. After the container liquid bag is produced, it needs to be tested for sealing.

[0003] Most existing leakage testing equipment for container liquid bag production uses water to test for leaks. Since the liquid bag filled with water is heavy, operators need to wait for the filling and draining of water. In addition, the water test must be carried out after drying before packaging and shipment.

[0004] Therefore, to address the above problems, a leakage alarm device for container liquid bag production can be designed, which changes the detection method and uses air pressure detection to perform leakage detection, thereby reducing waiting time and eliminating the drying process. Utility Model Content

[0005] In order to overcome the leakage problems of most existing container liquid bag production equipment, most of them use water to fill the liquid bag for leakage testing. Since the liquid bag filled with water is heavy, the operator needs to wait for the time of filling and draining water. In addition, the water test needs to be dried before packaging and shipment.

[0006] The technical solution of the utility model is: a leakage alarm device for container liquid bag production, comprising a test box, a first air pressure sensor, a second air pressure sensor, an alarm light, a buzzer, a main control module, a liquid bag body, a box door and an electric telescopic rod; the inner wall cross-section of the test box is circular, the first air pressure sensor is arranged on the outside of the test box, the second air pressure sensor is arranged on the inside of the test box, an alarm light is arranged above the test box, a buzzer is arranged above the test box, the main control module is arranged on one side of the test box, the liquid bag body is arranged on the inside of the test box, the box door is arranged on one side of the test box, and the electric telescopic rod is arranged on the outside of the box door.

After a certain pressure of gas is injected into the liquid bag body, the box door is closed to form a sealed environment in the test box. The air pressure in the liquid bag body is monitored in real time by the first air pressure sensor, and the air pressure in the test box is monitored in real time by the second air pressure sensor. The main control module receives the air pressure data in real time. When the air pressure in the liquid bag body drops and the air pressure in the test box rises, the main control module controls the alarm light to light up and the buzzer to sound a prompt, thereby prompting the operator that there is a leak in the current liquid bag body, realizing the function of leak detection by detecting air pressure, eliminating the drying process, and enhancing the practical value of the device.

[0008] Preferably, the main control module is electrically connected to the first air pressure sensor, the second air pressure sensor, the alarm light, the buzzer and the electric telescopic rod.

[0009] Preferably, a display screen is provided on the outside of the main control module, and a plurality of groups of operation buttons are provided on one side of the display screen.

[0015] 1. The device improves the detection method. The air pressure in the liquid bag body is monitored in real time by the first air pressure sensor, and the air pressure in the test box is monitored in real time by the second air pressure sensor. The main control module receives the air pressure data in real time. When the air pressure in the liquid bag body drops and the air pressure in the test box rises, the main control module controls the alarm light to light up and the buzzer to sound a prompt, thereby prompting the operator that there is a leak in the current liquid bag body. The function of leak detection by detecting air pressure is realized, so that the operator only needs to wait for the time to inject gas, and the drying process is eliminated, which enhances the practical value of the device.

[0025] See also Figure 3 In this embodiment, a rotating shaft 802 is provided on the side where the door 8 is connected to the test box 1, and a sealing ring 801 is provided on the side where the door 8 contacts the test box 1. The diameter of the sealing ring 801 is consistent with the diameter of the inner wall of the test box 1; the sealing ring 801 is used to increase the sealing performance between the door 8 and the test box 1 when the door 8 is closed.

[0026] See also Figure 4 In this embodiment, a mounting base 103 is provided on one side of the test box 1, and a reinforcing rib 104 is provided on the inner side of the mounting base 103. Rotating rods 902 are provided at both ends of the electric telescopic rod 9, and a rotating base 901 is provided on the outer side of the rotating rod 902. The rotating rod 902 is rotatably connected to the rotating base 901; the mounting base 103 is used to install the electric telescopic rod 9 on the outside of the test box 1, and the reinforcing rib 104 can strengthen the strength of the mounting base 103. The rotating rod 902 is rotatably connected to the rotating base 901, so that the extension and retraction of the electric telescopic rod 9 does not conflict with the opening and closing of the box door 8.

[0027] When performing a leak test, the liquid bag body 7 is placed in the test box 1, and the bag opening of the liquid bag body 7 is sealed and connected to the connecting valve 101. Then, gas is injected into the liquid bag body 7 through the air inlet pipe 102 connected to the external device to form a certain air pressure. Then, the electric telescopic rod 9 extends to push the box door 8 to close, so that a closed space is formed in the test box 1.

The main control module 6 receives the air pressure data in real time. When the air pressure in the liquid bag body 7 drops and the air pressure in the test box 1 rises, the main control module 6 controls the alarm light 4 to light up and controls the buzzer 5 to sound a prompt, thereby prompting the operator that there is a leak in the current liquid bag body 7, realizing the function of leak detection by detecting air pressure, eliminating the drying process, and enhancing the practical value of the device.
