Embodiment
In Fig. 1 ~ 2, a kind of SEA LEVEL VARIATION monitoring device, including flotation gear 1, rack 2, gear 3, the and of resistance wire tray 4
Fixed platform 5, fixed platform 5 are arranged on the upside of water level, and gear 3 and resistance wire tray 4 are arranged concentrically on the side of fixed platform 5, electricity
Hinder and resistance wire 6 is wound in wire tray 4, rack 2 and gear 3 engage, and the lower end of rack 2 connection flotation gear 1, the center of gear 3 is fixed and led
Electric pointer 7, the conductive top of pointer 7 contact with resistance wire 6, resistance wire initiating terminal 601 by wire successively with power supply 8, ammeter 9
Closed-loop path is formed with the conductive terminal tandem of pointer 7.
When water level is in minimum point, the conductive top of pointer 7 contacts with resistance wire initiating terminal 601.
The arc length of gear 3 corresponding to the resistance wire 6 is more than lowest water level to the length of peak level.
When specifically used, first, the suitable gear 3 of diameter and the rack of moderate length are selected according to the amplitude of variation of water level
2, the arc length of gear 3 corresponding to resistance wire 6 is more than lowest water level and is greater than minimum to the length of peak level, the length of rack 2
Length of the water level to peak level；Flotation gear 1 is placed on the water surface, and fluctuation of water table drives flotation gear 1 to move up and down, so as to
The length of the resistance wire 6 in access circuit is set to change, the electric current for ultimately resulting in the display of ammeter 9 is different；With water level
Rise, the length of the resistance wire 6 accessed in circuit, electric current diminishes；According to I=U/R=U/ (pL/S), U is voltage, and p is electricity
Resistance rate, S are resistance wire sectional area, and L is the length of resistance wire 6 in access circuit, can calculate resistance wire 6 in access circuit
Length, the arc length rotated according to the diameter of gear 3 and resistance wire tray 4 than gear 3 can be drawn, so that it is determined that water level rise or under
The height of drop.
The arc length of gear 3 corresponding to the resistance wire 6 is equal to lowest water level to the length of peak level.Rise when water level
When being highly more than peak level, the angle that conductive pointer 7 rotates exceedes angle corresponding to resistance wire 6, and now circuit disconnects, electric current
Zero is shown as, plays warning function.
6 a diameter of 3 ~ 6mm of resistance wire.Resistance is larger, and the amplitude of variation of electric current is larger, increases the sensitivity of device.
The material of conductive pointer 7 is copper.Electric conductivity is preferable.
The above embodiments are only optimal technical scheme of the present utility model, and are not construed as limit of the present utility model
System, the technical scheme that the scope of protection of the utility model should be recorded with claim, including the technical scheme that claim is recorded
The equivalents of middle technical characteristic are protection domain.Equivalent substitution i.e. within this range is improved, also in the utility model
Protection domain within.
