[0053] The supporting member 205 and the first test block are both disposed inside the volume cylinder 201;

[0054] The first test block is disposed on the supporting member 205 .

[0055] like Figure 2 As shown, in Example 1, the first test module 2 includes a capacity cylinder 201 and a base 206 that are threadedly connected, and the contact surfaces of the capacity cylinder 201 and the base 206 are provided with flexible rubber rings to make the connection tighter.

[0059] The sealing detection device also includes a second test module 5 and a second data module;

[0060] A second test block is arranged in the second test module 5;

[0062] The second data module is connected to the second test module 5 and is used to collect the input air pressure value and the output air pressure value of the second test module 5 .

[0063] like Figure 3 As shown, the second test module 5 includes a first cavity 501 and a second cavity 505 which are detachably connected and communicate with each other;

[0064] The first cavity 501 is provided with an air inlet, and the air supply module is connected to the air inlet;

[0067] The second test module 5 further includes a sealing unit 504;

[0068] The sealing unit 504 is disposed on a contact surface between the first cavity 501 and the second cavity 505 .

[0069] The utility model sets a sealing unit 504 on the contact surface of the two cavities of the second test module 5 to further enhance the sealing of the two cavities to ensure that the leakage source is the test block, thereby improving the detection accuracy of the detection device of the utility model.

[0070] The second data module includes a first acquisition unit 7 and a second acquisition unit 6;

[0071] The first collecting unit 7 is connected to the air inlet of the first cavity 501 and is used to collect the input air pressure value of the first cavity 501;

[0072] The second collecting unit 6 is connected to the exhaust port of the second cavity 505 and is used to collect the output air pressure value of the second cavity 505 .

[0073] like Figure 3As shown, in Example 2 of the present utility model, the side wall and bottom surface of the second test block are connected to the inner wall of the second cavity 505, and the second test block is composed of block concrete 506 inside and sealing material coating 507 on the surface. In order to fully simulate the cave environment of the high-pressure gas storage cave, the surface of the second test block corresponding to the exhaust port of the second cavity has no sealing material coating 507. The shape of the second test block can be any one of a cylinder and a prism, and the second collection unit 6 is a barometer 508.

[0074] like Figure 1 As shown, in Example 3 of the utility model, the outlet pipe of the pressurizing unit 1 is provided with a main switch 9, which can control whether the first test module 2 and the second test module 5 participate in the detection work, and the first test module 2 and the second test module 5 are respectively provided with a first sub-switch 12 and a second sub-switch 13 at the connection between the first test module 2 and the second test module 5 and the gas storage tank 10, which can be used independently or in combination. Any one or more of the first test module 2 and the second test module 5 can be selected as required to test the sealing of the test block, and the pressure can be quickly released through the pressure relief unit 8 after the test is completed.

[0075] The process of using the first test module 2 of the utility model to perform sealing detection is as follows:

[0076] The sealing material 202 of the first test block is applied to the surface of the hollow spherical concrete 204 to prepare the first test block. The first test block may also be in other shapes. The spherical shape is used in this embodiment mainly to facilitate the application of the sealing material and to make the test block more evenly compressed.

[0077] A wireless pressure sensing module 3 is embedded in the first test block, the pressurizing unit 1 is started to implement pressure loading, and the air is compressed into the gas storage tank 10 through the pipeline. The gas storage tank 10 sends the air pressure out through the pipeline, and the air pressure is transmitted to the first test module 2.

[0078] When the first data module 4 reaches the set pressure (in other embodiments, it can also be when the monitoring unit 11 and the first data module 4 both reach the set pressure), close the main switch 9; observe the pressure loss of the first data module 4, and at the same time, the wireless pressure sensing module 3 detects the increase in air pressure, and finally the time taken for the two pressure values ​​to be the same. If the time taken for the two pressure values ​​to be the same is greater than or equal to 30 minutes, it is considered that the sealing of the first test block meets the standard.

[0079] In other embodiments, the pressure stabilization time after the monitoring unit 11 and the first data module 4 both reach the set pressure may also be obtained. If the pressure stabilization time is greater than or equal to 30 minutes, it is considered that the sealing of the first test block meets the standard.

[0080] The process of using the second test module 5 of the utility model to perform sealing detection is as follows:

[0081] After the second test block is placed into the second cavity 505 , the first cavity 501 and the second cavity 505 are connected by bolts 503 and nuts 502 .

[0082] The pressurizing unit 1 is started to implement pressure loading, and the air is compressed into the air storage tank 10 through the pipeline. The air storage tank 10 sends the air pressure out through the pipeline, and the air pressure is transmitted to the second test module 5.

[0083] When the first collection unit 7 reaches the set pressure (in other embodiments, the monitoring unit 11 and the first collection unit 7 can also reach the set pressure), turn off the main switch 9 and stabilize for 30 minutes, and observe whether the second collection unit 6 has a reading. If not, it is considered that the seal is very good; if it is between 0 and 5 kPa (including 5 kPa), it is considered that the seal is good; if it is greater than 5 kPa, it is considered that the seal is not good.

[0084] The utility model compares the monitoring unit 11 with the first data module 4. When both reach the set pressure, subsequent judgment is performed to determine that the pressure loss at the first data module 4 is not caused by leakage in the gas pipeline of the pressurizing unit 1, thereby eliminating the interference of leakage of experimental equipment and improving the accuracy of the utility model.

[0085] After the test, the pressure relief unit 8 is opened to release the gas in the gas storage tank 10.

[0086] The utility model utilizes the air supply module to pressurize the upper surface of the second test block to detect the one-way sealing performance of the upper surface of the second test block, and has simple operation and principle.

[0087] Compared with the prior art, the utility model has the following beneficial effects:

[0088] (1) The utility model sets the wireless pressure sensing module inside the first test block to collect the air pressure of the input air pressure penetrating from the outside into the first test block to ensure that the air leakage source is the first test block. Therefore, the data obtained by the utility model has higher accuracy;

[0089] (2) The utility model sets a monitoring unit at the air outlet of the pressurizing unit, and judges whether the air pipelines of the air supply module and the first test module are leaking by comparing the air pressure value detected by the monitoring unit with that detected by the first data module, thereby further reducing the detection error of the utility model and improving the accuracy;

[0090] (3) The utility model is provided with a second test module and a second data module for sealing detection. The device is simple and easy to operate, and can quickly and accurately detect the sealing of the test block;

[0091] (4) The second test module of the utility model is provided with a first cavity and a second cavity which are connected and detachably connected, so as to facilitate the taking and placing of the test block and save the experimental time;

[0092] (5) The utility model sets a sealing unit on the contact surface of the two cavities of the second test module to further enhance the sealing of the two cavities to ensure that the leakage source is the test block, thereby improving the detection accuracy of the detection device of the utility model.
