[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 3 As shown, this utility model provides a float-type liquid level gauge with self-testing function, including a transmitter body 11. A conduit 12 is provided at the bottom of the transmitter body 11. The conduit 12 provides a guide path for the device to move up and down, allowing the user to sense changes in liquid level by moving along the conduit 12, thus improving the accuracy and reliability of the liquid level measurement. A counterweight 18 is detachably connected to the bottom of the conduit 12. The counterweight 18 increases the weight at the bottom of the conduit 12, keeping the conduit 12 vertically stable in the liquid, thus improving the overall stability of the device.

[0025] A connecting flange 13 is fitted onto the conduit 12, allowing the user to securely connect the conduit 12 to the transmitter body 11 via the connecting flange 13. This facilitates assembly and disassembly of the device, improving its ease of installation and maintenance. The transmitter body 11 is connected to the connecting flange 13 via a fastening nut 19. The fastening nut 19 securely binds the transmitter body 11 to the connecting flange 13, enabling the user to assemble the equipment and enhancing the overall stability and reliability of the device. A float 14 is located below the connecting flange 13, allowing the float to move up and down with the liquid level through buoyancy. This allows users to determine the liquid level via the float 14, improving the accuracy of the liquid level measurement. A scraper 15 is detachably connected to the bottom of the float 14 and is fitted onto the guide tube 12. The scraper 15 cleans the guide tube 12 as the float 14 rises and falls with the liquid level, removing impurities adhering to the surface of the guide tube 12 and enhancing the self-cleaning capability of the device. The scraper 15 has multiple sets of flow guide holes, which reduce the resistance of the scraper 15 to the liquid flow as it moves with the float 14, minimizing the impact on the accuracy of the liquid level measurement and improving the smoothness and stability of the device during operation.

[0026] A first baffle 16 is provided above the float 14, and a second baffle 17 is provided below the float 14. Both the first baffle 16 and the second baffle 17 are sleeved on the guide tube 12. The setting of the first baffle 16 and the second baffle 17 can define the movement range of the float 14, so that the user does not have to worry about the float 14 deviating from its trajectory due to liquid level fluctuations. This improves the stability and reliability of the liquid level measurement of the device. The user can effectively limit the displacement of the float 14 through the first baffle 16 and the second baffle 17, so that the device can avoid measurement errors caused by excessive movement of the float 14 and improve the accuracy of liquid level measurement of the device.

[0027] like Figures 2 to 5 As shown, a self-test module is installed inside the float 14. The self-test module includes a mounting cylinder 21, which provides a stable space for the self-test module. The mounting cylinder 21 effectively protects the internal components, reduces interference from the external liquid environment, and improves the protection performance and stability of the self-test module. A micro switch 22 is installed inside the mounting cylinder 21. The micro switch 22 can sense triggering actions, so that when the device is subjected to a specific external force, the micro switch 22 can react to realize the circuit opening and closing, allowing the user to promptly obtain whether the float 14 is moving out of control. The presence of abnormal signals improves the timeliness and accuracy of fault detection in this device. A trigger head 23 is located below the micro switch 22. The trigger head 23 is connected to the mounting cylinder 21 via a damping rod 26. A spring is installed inside the damping rod 26. Through the setting of the damping rod 26 and the internal spring, the trigger head 23 will only move upward to touch the micro switch 22 when it senses a certain strength and continuous external force. This allows the user to effectively avoid false triggering caused by slight shaking of the float 14 during normal movement or slight fluctuations of the liquid, thus improving the anti-interference capability of the device's self-test function.

[0028] The micro switch 22 is provided with an alarm 24. When the micro switch 22 is closed due to the action of the trigger head 23, the alarm 24 can send an alarm signal, so that the user can perceive the abnormal situation of the floating ball 14, and the timeliness of the fault warning of the device is improved. The power supply 25 is arranged in the mounting cylinder 21. The stable electrical connection between the power supply 25, the micro switch 22 and the alarm 24 is ensured, the instability of power supply caused by external environmental factors is avoided, the normal performance of the self-checking function is ensured, and the stability and reliability of the device are improved. The power supply 25 is electrically connected with the micro switch 22 and the alarm 24. When the floating ball 14 is abnormal and the trigger head 23 triggers the micro switch 22, the power supply 25 provides power for the alarm 24, so that the alarm 24 sends an alarm. The self-checking module can timely convey the abnormal information of the floating ball 14 to the user, the response ability of the device in dealing with sudden failure is improved, and the stable operation of the device is ensured.

[0029] The sealing cover 27 is arranged at the top of the mounting cylinder 21. The sealing cover 27 can effectively prevent external impurities from entering the mounting cylinder 21, reduce the erosion of the external environment, improve the protection and service life of the device, and ensure the stability of the alarm 24. At the same time, the signal sent by the alarm 24 can be timely and smoothly transmitted. The user can ensure that the alarm 24 is kept in a proper position in the mounting cylinder 21, so that the device can send an alarm signal in time when the floating ball 14 is abnormal. The reliability of the fault warning function of the device is improved. The sealing ring is arranged between the sealing cover 27 and the alarm 24. The sealing effect is further improved by the sealing ring, and the penetration of small particles or water vapor into the mounting cylinder 21 is reduced. The inside of the mounting cylinder 21 can maintain a dry and clean environment, and the overall sealing and waterproof and dustproof ability of the device is improved.
