[0051] This invention proposes a water level sensor lifespan testing device for use in water level sensor testing processes. This invention does not limit the type of water level sensor, but the structure of this water level sensor lifespan testing device is particularly suitable for lifespan testing of more than 10 water level sensors that operate on air pressure.

[0052] Overall, the water level sensor lifespan testing device proposed in this utility model mainly includes a frame 1, a control cabinet 2, a water level sensor mounting unit, a fixing unit, and a detection tube unit. See also... Figure 1 It shows the arrangement of the frame 1, control cabinet 2, water level sensor mounting unit, fixing unit and detection tube unit.

[0053] To achieve the goal of large-scale parallel detection of water level sensor lifespan and address the issues in the background technology regarding water level sensors in water level detection devices...

[0054] As a core component, the reliability of the sensor directly affects the operational stability of the equipment, and the sensor's lifespan is a crucial factor in ensuring equipment reliability. Existing technologies primarily use single-unit testing equipment to perform lifespan tests on individual water level sensors. This requires connecting each sensor individually and simulating pneumatic conditions, necessitating repeated loading, unloading, and parameter configuration. Furthermore, it cannot simultaneously generate multiple sets of differentiated pressure parameters, leading to the need for batch testing under high-pressure, low-pressure, and pulse conditions, exacerbating equipment downtime and wear. Therefore, the technical solution provided in this embodiment utilizes a water level sensor mounting unit to accommodate multiple water level sensors to be tested. Each water level sensor is provided with a pneumatic outlet pipe 5 for testing, enabling simultaneous testing of 20 water level sensors within the same device. Data feedback is displayed on the control cabinet 2, effectively improving testing efficiency and providing rapid quality inspection feedback.

[0055] Specifically, such as Figure 1 As shown, the control cabinet 2 is installed on the top of the frame 1, and an operating area is left on the top of the frame 1. The bottom of the frame 1 is equipped with casters 6, which makes it easy to move to a position that is convenient for testing, and it is highly adaptable.

[0056] A water level sensor mounting unit is provided within the operating area. Mounting holes 3 are provided within the mounting unit corresponding to multiple water level sensors to be tested, enabling the positioning of the water level sensors during testing. To ensure the stability of the water level sensors during testing, a fixing unit is installed on the mounting unit, positioned above each mounting hole 3, using spring pressure to press down on the water level sensor from the top. Furthermore, in this embodiment, a detection tube unit is used to equip each water level sensor with an air outlet pipe 5 connected to output air pressure, achieving simultaneous detection.

[0057] As mentioned above, the water level sensor is located in the operating area for detection. Considering the convenience of replacing the water level sensor in the water level sensor installation unit, the operating area is set to be open. A connecting rod 9 is installed on the top of the frame 1 away from the control cabinet 2, facing upwards. A baffle 8 is installed between the connecting rod 9 and the control cabinet 2. The detection space is formed by a pair of baffles 8, the control cabinet 2, and the sliding plate 3. A sliding groove 10 is provided on the inner side of the connecting rod 9 above the frame 1. The sliding grooves 10 on the pair of connecting rods 9 are arranged opposite each other. A slot 11 is opened on the top of the frame 1 near the operating surface, and its two ends are connected to the sliding groove 10. The sliding plate 12 is inserted into the sliding groove 10 and the slot 11 to form a blocking effect on the water level sensor installation unit. At the same time, in order to facilitate the up and down movement and disassembly of the sliding plate 12, a handrail 13 is installed on the side of the sliding plate 12 away from the water level sensor.

[0058] Specifically, the water level sensor mounting unit includes a base plate 14, a mounting plate 16, and a top plate 17 arranged parallel from bottom to top to provide a mounting position for the water level sensor. The bottom of the base plate 14 is mounted on the top of the frame 1 via foot 19. A pair of support plates 15 are provided, each vertically mounted on the base plate 14. The mounting plate 16 is horizontally mounted between the pair of support plates 15. The bottom of the mounting plate 16 is mounted on the support plate 15 via an L-shaped bracket. Mounting holes 3 are provided on both sides of the elongated side of the mounting plate 16, and the mounting holes 3 are used to place the water level sensor. Then, the top plate 17 is arranged parallel to the top of the mounting plate 16 and is mounted on the support plate 15 with bolts. The top plate 17 has a through hole 18 for mounting and fixing units, which is located directly above the mounting holes 3. The through hole 18 is used to mount and fix the unit, thereby creating a pressing effect on the water level sensor.

[0059] Preferably, the fixing unit comprises a fixing rod 20, a spring 21, and a plug 22. The fixing rod 20 is integrally formed from top to bottom with a plug connecting end 23, a body 24, and a plug. The outer diameter of the plug connecting end 23 is smaller than the outer diameter of the body 24. A plug 22 is installed on the plug connecting end 23. After installation with the top plate 17, the plug 22 is located above the top plate 17. The fixing rod 20 is also fitted with a spring 21. After installation, the top of the spring 21 rests against the bottom of the top plate 17, and the bottom is set on the fixing rod 20 and also rests against the limiting plate 25. In addition, the outer diameter of the limiting plate 25 is larger than the inner diameter of the through hole 18, and the outer diameter of the body 24 is not larger than the inner diameter of the through hole 18, which can restrict the installation position of the spring 21.

[0060] like Figure 4 As shown, in order to configure an air pressure detection path for each water level sensor, the detection tube unit includes an air inlet pipe 4 and an air outlet pipe 5. The air outlet end of the air inlet pipe 4 is distributed below the mounting plate 16 through a branch pipe 26, and an air outlet pipe 5 is installed on each mounting hole 3 on the branch pipe 26. The air outlet pipe 5 is connected to the water level sensor through a flexible hose. The test results are displayed on the display 27 on the control cabinet 2 to achieve the purpose of real-time detection.

[0061] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
