Detailed Description
The following description of the embodiments with reference to the drawings is provided to describe the embodiments of the present invention, and the embodiments of the present invention, such as the shapes and configurations of the components, the mutual positions and connection relationships of the components, the functions and working principles of the components, the manufacturing processes and the operation and use methods, etc., will be further described in detail to help those skilled in the art to more completely, accurately and deeply understand the inventive concept and technical solutions of the present invention.
As shown in fig. 1, the structure of the electric oil level alarm device is as shown in fig. 1, the electric oil level alarm device is provided with a slideway 7 and a movable column 6 positioned in the sliding part, the slideway 7 and the movable column 6 form a structure similar to a piston, the movable column 6 can move up and down in the slideway 7, the opening of the slideway 7 faces downwards when fixed, the bottom end of the movable column 6 is connected with a floating block 1 positioned outside the slideway 7, two contacts 8 on a top plate are not connected, the movable column extends to the outside of a (oil tank) through leads and is connected with a battery 12 and an alarm 11 in series to form an alarm circuit, the alarm circuit is in a short circuit state under normal state, the alarm 11 does not work, when the movable column 6 rises to contact the top plate, the two contacts 8 on the top plate are respectively contacted with the two contacts 8 on the movable column 6 to conduct the alarm circuit, and the alarm 11 is powered on to alarm.
Three connecting rods are adopted to the fixed mode of kicking block 1, specifically include first connecting rod 2, second connecting rod 5 and third connecting rod 4, the middle part of second connecting rod 5 is equipped with rotatory fulcrum 3, rotatory fulcrum 3 passes through the support to be fixed in the bottom of activity post 6, second connecting rod 5 can use rotatory fulcrum 3 to rotate as the axle like this, 4 the one end of second connecting rod 5 is passed through the pivot and is connected with 2 one end of first connecting rod, the other end rigid coupling of first connecting rod 2 has kicking block 1, the other end of second connecting rod 5 is connected with 4 one end of third connecting rod through the pivot, the other end of third connecting rod 4 is fixed on 7 outer walls of slide through the pivot. Can rise after floating block 1 receives buoyancy to push up movable column 6, because floating block 1 can be located higher position because of third connecting rod 4, make to reach warning position back, the buoyancy that makes progress that floating block 1 submerges in oil also can not be too big, is less a lot than floating block 1 is located movable column 6 bottom, thereby can reduce the pressure between the transition refuels back contact, protection circuit structure increases the life of device.
The parallelly connected speaker of alarm 11 preferred adoption and alarm lamp, can remind the personnel of refueling to stop the oiling inwards through the mode of warning and flashing light, prevent that the oil level liquid level is too high, surpass alert border position, speaker and alarm lamp can be installed near oiling operation area, close alarm 11 under the convenient non-oiling state, avoid the wrong report alert, can establish ties on warning circuit and have switch 10.
The working principle of the oil level alarm device is as follows: after the switch 10 is closed, along with the increase of the oil injection amount, the liquid level of the oil level rises, when the oil level reaches a certain height, the buoyancy force acts to push the piston to rise, the movable contact and the static contact are connected to form a closed loop, the loudspeaker rings, the alarm lamp also flickers to indicate that the oil level reaches the warning position, the oil injection can be stopped, and finally, the power switch 10 is turned on, and the circuit is disconnected.
The oil level alarm device is arranged on a top position in an oil tank of the oil tank truck, for example, on an oil storage tank cover, aiming at a sealed tank for storing oil in places such as the oil tank truck and the like, and can prevent the liquid level of the oil level from being too high and exceeding the position of an alarm limit. Because fuels such as gasoline, diesel oil and the like belong to dangerous goods and materials, a special oil tank truck is required to be used for transportation in the processes of storage, transportation and the like. When pouring into oil in the tank wagon, when the oil level rose to a take the altitude, the pilot lamp of this alarm 11 will flash, and electric horn will sound, reminds the personnel of refueling to stop oiling inwards, can avoid appearing refueling phenomenon such as not enough or too much, improves tank wagon's economic effect and safe in utilization.
The low voltage (about 6V) of the power supply of the designed circuit ensures that the moving contact and the static contact do not burst high voltage sparks at the jointing moment to ignite fuel gas, thereby ensuring the safety of vehicles and people. Meanwhile, the required voltage of the electric horn and the indicating lamp is also ensured by the power supply voltage. And the electric horn and the indicator light are connected in parallel in the circuit, when one of the electric horn and the indicator light is out of order due to a certain reason, the other electric horn and the indicator light still can play a role in alarming, and the alarming reliability of the whole circuit is greatly improved. This floater formula alarm 11 has adopted folding telescopic link, the installation of being convenient for, can adjust the floater height as required simultaneously, adapts to the oil storage tank of different volume sizes.
The utility model has been described above with reference to the accompanying drawings, it is obvious that the utility model is not limited to the specific implementation in the above-described manner, and it is within the scope of the utility model to apply the inventive concept and solution to other applications without substantial modification.
