As shown in Figure 4 and Figure 8, further:

The base 2a is also provided with an alarm assembly 2h, the alarm assembly 2h includes an alarm 2h1 and sensors 2h2 corresponding to the number of sliders 2e2, and all the sensors 2h2 are fixedly connected to a plurality of sliders 2e2 in turn, and the alarm 2h1 is located on the bottom of the base 2a. top.

Based on the above-mentioned embodiments, the technical problem to be solved in the present application is how the shock-absorbing mechanism 2 can give an early warning to the staff. For this reason, this application detects the sliding displacement distance through the setting of the sensor 2h2. When the displacement of multiple sliders 2e2 exceeds the set threshold, an electrical signal will be sent to the back-end controller, and the back-end controller will send The electric signal is sent to the alarm 2h1, so that the alarm 2h1 emits a buzzer or flashes a light, thereby giving an early warning and a reminder to the staff, so as to ensure that the protected tank 3 can be effectively protected.

The above examples only represent one or several implementations of the present invention, and the descriptions thereof are more specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
