[0014] The utility model is described in detail below with reference to the accompanying drawings:

[0015] like Figures 1-3 As shown, a liquid level automatic detection alarm tool includes a circular positioning plate 1. The diameter of the positioning plate 1 is adapted to the diameter of the tank truck observation port. The positioning plate 1 can be fixed to the tank truck observation port. Specifically, the edge of the positioning plate 1 is provided with multiple clamping members 2 along the circumference of the positioning plate 1. In this embodiment, three clamping members 2 are provided. The clamping members 2 include a base 201 fixed to the positioning plate 1, a support plate 202 is provided on the base 201, a through hole 203 is provided on the support plate 202, and a pull rod 204 is provided above the base 201. The pull rod 204 is arranged radially along the positioning disk 1, and the pull rod 204 passes through the through hole 203. A yoke rod 205 is fixed at one end of the pull rod 204, and a spring 206 is sleeved on the pull rod 204. One end of the spring 206 is fixed on the support plate 202, and the other end is fixed to the end of the pull rod 204 away from the yoke rod 205. After the positioning disk 1 is placed at the observation port of the tank truck, the spring 206 can apply elastic force to the pull rod 204, so that the yoke rod 205 yokes the side wall of the observation port, thereby completing the installation of the positioning disk 1.

[0016] The positioning disc 1 is fixed with a sleeve 3 which is perpendicular to the positioning disc 1, the sleeve 3 is located at the circular part of the positioning disc 1 and passes through the middle part of the positioning disc 1, the top end of the sleeve 3 is provided with an audible and visual alarm 4, the audible and visual alarm 4 is used for issuing audible and visual alarm to promote the operator to reach the set value of the liquid level in the tank car, the audible and visual alarm 4 comprises an alarm body 401, the bottom of the alarm body 401 is provided with a trigger switch 402, the trigger switch 402 is located in the sleeve 3, the sleeve 3 is provided with a movable rod 5 which can move along the length direction of the sleeve 3, the bottom end of the movable rod 5 extends from the bottom end of the sleeve 3, the bottom end of the movable rod 5 is provided with a float ball 6, the float ball 6 can float on the surface of the liquid in the tank car and can move up and down with the liquid level, the bottom end of the movable rod 5 is provided with a contact 7 which corresponds to the trigger switch 402, when the contact 7 contacts with the trigger switch 402, the audible and visual alarm 4 can alarm.

[0017] In addition, in order to prevent the movable rod 5 from being taken out of the sleeve 3, the side wall of the sleeve 3 is provided with a limiting groove 8 along the length direction of the sleeve 3, the movable rod 5 is provided with a limiting rod 9 which is located in the limiting groove 8 and can move in the limiting groove 8, the limiting rod 9 can prevent the movable rod 5 from being taken out of the sleeve 3.
