[0027] Some common gas sensors, such as combustible gas sensors, including hydrogen sensors and carbon monoxide sensors, encounter complex operating conditions during operation. For example, damage to the gas sensor's own fixing components can cause the gas sensor to suspend in mid-air; when the gas flow velocity around the gas sensor is high, the gas sensor is prone to swaying; and when testing gas sensors, it is difficult to detect the impact of the gas sensor being suspended on the reading, i.e., it is difficult to determine the reliability of the gas sensor in a suspended state. It is often necessary to test the reliability of the gas sensor in a suspended state.
[0028] This invention proposes a swing test device for a gas sensor.
[0029] Please see Figure 1 In one embodiment of this utility model, the swing test device for the gas sensor includes:
[0030] Test chamber 1 is used to contain the gas to be tested;
[0031] The swing rod 2 has a swing end and a connecting end, the connecting end being rotatably configured along an axis extending in a first horizontal direction, such that the swing end is swinging within the test chamber 1; and,
[0032] Fixing member 3 is provided on the swing end, and the fixing member 3 is used to install the gas sensor to be measured.
[0033] The technical solution of this utility model, by setting up a test chamber 1, can keep the concentration of the gas to be tested around the gas sensor constant. Then, by controlling the swing and swing amplitude of the swing arm, the gas sensor to be tested can be driven to swing. By detecting the change in the reading of the gas sensor to be tested during the swing, the influence of the reading of the gas sensor to be tested when it is in a suspended state can be detected. Overall, this improves the problem of difficulty in judging the reliability of the gas sensor when it is in a suspended state.
[0034] A second driving component 22 is connected between the connecting end and the inner wall of the top side of the test chamber 1. The second driving component 22 is used to drive the swing rod 2 to swing. The swing amplitude of the swing rod 2 can be controlled by the second driving component 22.
[0035] The second driving component 22 can be a motor or any other component that enables automatic oscillation.
[0036] The fixing member 3 is rotatably mounted on the swing end along an axis extending vertically. By controlling the rotation of the fixing member 3, the gas sensor under test can be driven to rotate, thereby changing the relative swing direction of the gas sensor under test and realizing multi-directional swing of the gas sensor under test.
[0037] Please see Figure 1 Specifically, a rotating device 21 is fixedly installed on the swing end. The rotating device 21 has a rotating shaft, and the fixing member 3 is fixedly installed on the rotating shaft of the rotating device 21. The fixing member 3 is located on the side of the rotating device 21 away from the swing rod 2. Preferably, the rotating shaft of the rotating device 21 is coaxial with the swing rod 2. The rotating device 21 can be a motor. Through the rotating device 21, the rotation of the fixing member 3 can be controlled while it is being rotated.
[0038] The swing test device for the gas sensor also includes a collision plate 4, which is located inside the test chamber 1 and on the swing path of the swing end, so that the gas sensor under test collides with the collision plate 4. When the gas sensor under test collides with the collision plate 4, the change in the reading of the gas sensor under test during the collision can be detected. By controlling the rotation of the fixing member 3, the collision point on the gas sensor under test can be changed, thereby detecting the change in the reading of the gas sensor under test when it is collided at different collision points, thus realizing the reliability test of the gas sensor under test when it is suspended and collides.
[0039] The position of at least one of the connecting end and the collision plate 4 is adjustable to change the collision point of the gas sensor. By changing the distance between the connecting end and the collision plate 4, the collision point on the sensor can be changed.
[0040] Specifically, the collision plate 4 is movably disposed, and the swing test device for the gas sensor further includes a first driving member 5. The first driving member 5 has a first push-pull rod 51 that moves along a second horizontal direction. The second horizontal direction and the first horizontal direction are two mutually perpendicular directions in the horizontal plane, and the collision plate 4 is correspondingly connected to the first push-pull rod 51.
[0041] By controlling the first push-pull rod 51, the first push-pull rod 51 can drive the collision plate 4 to move, thereby changing the distance between the connecting end and the collision plate 4.
[0042] The first driving component 5 includes a hydraulic cylinder and an electric push rod. The first driving component 5 is preferably a hydraulic cylinder and is located inside the test chamber 1.
[0043] The collision plate 4 is perpendicular to the first push-pull rod 51, and the first driving member 5 is located on the side of the collision plate 4 away from the swing rod 2, which can reduce the overall interference between the swing rod 2 and the first driving member 5.
[0044] In one embodiment, two collision plates 4 are provided, and the swing rod 2 is located between the two collision plates 4. This allows the gas sensor to undergo two collisions within one swing cycle of the swing rod 2, improving the detection efficiency of the gas sensor.
[0045] Please see Figure 1 The test chamber 1 is a rectangular box, and the two collision plates 4 are located at both ends of the test chamber 1 along its length. The outer periphery of the collision plates 4 is sealed against the inner periphery of the test chamber 1, so that a sealed test space 11 is formed between the two collision plates 4. The gas to be tested is located in the test space 11, which reduces the amount of gas required by the test chamber 1.
[0046] The gas sensor swing test device also includes a gas concentration detector 6, which is located inside the test chamber 1. The gas concentration detector 6 enables real-time detection of the concentration of the gas to be tested within the test chamber 1, allowing for comparison of the reading difference between the gas sensor and the gas concentration detector 6.
[0047] The fixing member 3 includes a clamping member, which can be a device for clamping and fixing the gas sensor to be tested, and the clamping member does not affect the detection function of the gas sensor to be tested.
[0048] The test chamber 1 is connected to a gas supply assembly 7. Through the gas supply assembly 7, a certain concentration of the gas to be tested can be sent into the test chamber 1, so that the concentration of the gas to be tested in the test chamber 1 reaches the required concentration.
[0049] The air supply assembly 7 includes an air supply component 71 and an air supply pipe 72. An air supply valve 73 is provided on the air supply pipe 72. The air supply valve 73 can be used to control the interruption of the air supply pipe 72. The air supply valve 73 can be a solenoid valve. The air inlet of the air supply pipe 72 is connected to the air outlet of the air supply component 71, and the air outlet of the air supply pipe 72 is connected to the test chamber 1. Specifically, the air outlet of the air supply pipe 72 is located in the test space 11.
[0050] Through the cooperation of the gas supply component 71 and the gas supply pipe 72, gas can be delivered into the test space 11.
[0051] The gas supply component 71 can be a gas generating component or a gas cylinder. The gas supply pipe 72 is detachably connected to the gas supply component 71, which facilitates the supply of different test gases into the test chamber 1 according to different gas sensors.
[0052] Please see Figure 1The test chamber 1 is connected to an exhaust assembly 8, which can exhaust the gas inside the test chamber 1 to the outside of the test chamber 1 after the gas sensor to be tested is completed, or when the gas to be tested needs to be replaced.
[0053] The exhaust assembly 8 includes an exhaust pipe 81 and an exhaust valve 82. The exhaust pipe 81 is connected to the test chamber 1, specifically, the exhaust pipe 81 is connected to the experimental space. The exhaust valve 82 is located on the exhaust pipe 81. The exhaust valve 82 can be a solenoid valve. By controlling the opening and closing of the exhaust valve 82, the on / off state of the exhaust pipe 81 can be controlled, thereby controlling the exhaust of the test chamber 1.
[0054] The gas sensor swing test apparatus also includes a display control module 9, which is connected to the gas sensor under test. The display control module 9 can display the reading of the gas sensor under test.
[0055] The display control module 9 can also be electrically connected to the first driving component 5 to control the movement of the collision plate 4.
[0056] The display control module 9 can also be electrically connected to the second drive component 22 to control the swing amplitude of the swing rod 2; the display control module 9 can also be electrically connected to the gas supply valve 73, the exhaust valve 82, and the gas supply component 71 to realize the exhaust, filling, and ventilation of the test space 11. The display control module 9 can also be electrically connected to the rotating device 21 to control the rotation of the gas sensor under test. The display control module 9 can also be connected to the gas concentration detector 6 to realize the real-time detection and display of the gas concentration in the test space.
[0057] The display control module 9 can be a computer.
[0058] In the embodiments of this utility model, by controlling the swing and rotation of the gas sensor under test, the reliability of the gas sensor under test can be detected when it swings and collides.
