Detailed Description

Example 1:

the preferable scheme is as shown in fig. 1, fig. 2 and fig. 8, the gap early warning device between the equipments comprises a base 1, wherein one end of the base 1 is provided with a trigger switch 2, the other end of the base 1 is provided with a magnetic adsorption part 3, and the magnetic adsorption part 3 is used for being adsorbed on the casing of the equipment; the trigger switch 2, the alarm lamp 4, the buzzer 5 and the power supply form an alarm circuit, and the alarm lamp 4 and the buzzer 5 are arranged on the side wall of the base 1.

The base 1 is a hollow cylinder structure, the power supply is a dry battery, and the dry battery is arranged in the base 1. The alarm lamp 4 adopts an LED flashing alarm lamp, and the model number of the alarm lamp is LTE-3051.

Further, the number of the trigger switches 2 is plural, and the plural trigger switches 2 are arranged in parallel.

Furthermore, a main switch is connected in series on the alarm circuit.

Further, the magnetic adsorption member 3 is two permanent magnet blocks, and the two permanent magnet blocks are symmetrically arranged on the base 1. The two magnetic adsorption pieces 3 can improve the stability of the device.

The trigger switch is a proximity switch or a button-type mechanical switch, and the trigger switch in the present embodiment is preferably a button-type mechanical switch.

The working principle of the device is as follows:

as shown in fig. 8, the alarm circuit includes an alarm lamp 4, a main switch, a buzzer, a trigger switch I, a trigger switch II, and a power supply. Specifically, the magnetic adsorption piece 3 enables the whole device to be fixed on a protected component (not limited to a cylindrical device 6) to prevent falling, the trigger switch I and the trigger switch II are in a normally open state, when the trigger switch detects that a gap between the protected component and a hoisting component is smaller than a set value, the distance sensor controls the trigger switch to be closed, the alarm flashing lamp is turned on, and the buzzer works; when the clearance continues to reduce, base 1 can play the support protection effect, can guarantee that the clearance is not less than the thickness of base 1, and protection device is not damaged.

The thickness of the base 1 is set to k, the distance from the sensor to the base 1 is set to s, and the height of the component to be protected is set to h. The clearance between the hoisting part and the protected part is D. Put into the device hoist and mount part with by in the protection part clearance, utilize the magnetism to adsorb on by the protection part, closed main switch, hoist and mount part is gradually close to by the protection part:

case 1: the clearance D is larger than k + s, the distance sensor controls the alarm circuit to be disconnected, the alarm flashing lamp is not on, and the buzzer does not work.

Case 2: the clearance k + s > D > k, and distance sensor control alarm circuit switches on, and the warning flashing light is bright, and buzzer work, the device plays alarming function.

Case 3: the clearance D = k, and hoist and mount part continues to be close to by the protection part, because the effect of base 1, clearance D remains for k all the time, and there is the clearance all the time between hoist and mount part and the by the protection part, can not take place the danger of collision damage equipment, and the device plays the protect function.
