Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of end side panel of the present utility model and front-back side panel, base plate.
In figure: rustless steel container 1, push up uncovered 2, top board 3, data cable line 4, end side panel 5, anti-wave baffle 6, guide rod 7, magnetic ball float 8, base plate 9, front-back side panel 10, water delivering orifice 11, electrically operated valve 12, draw-in groove 13, adhesive tape 14.
Embodiment
As shown in the figure, this dam infiltration amount instrument, comprise rustless steel container 1 and control circuit, the top of described rustless steel container 1 is provided with top board 3 and top uncovered 2, described top board 3 bottoms are connected with anti-wave baffle 6, the side panel of described rustless steel container 1, in the space that top board 3 and anti-wave baffle 6 form, be provided with dry-reed type float ball liquid level sensor, base plate 9 belows of described rustless steel container 1 are provided with electrically operated valve 12, described dry-reed type float ball liquid level sensor is made up of guide rod 7 and magnetic ball float 8, in described guide rod 7, be provided with successively from the bottom to top four switch triggering points, be respectively timing sign on trigger point, END instruction trigger point when little volumometer, END instruction trigger point when large volumometer, electrically operated valve 12 is opened imperative instruction trigger point.Described top board 3 connection data cable 4 are stretched out in guide rod 7 tops of described dry-reed type float ball liquid level sensor, and described data cable line 4 connects into described control circuit.In the present embodiment, described rustless steel container 1 is rectangular-shaped, and end side panel 5 is movable, is plugged in the draw-in groove 13 that described base plate 9 and forward and backward side plate 10 form, and three's surface of contact is provided with sealing joint strip 14.Described electrically operated valve 12 is open type, only in the time measuring beginning, just closes, and after measurement finishes, opens, and the water in rustless steel container 1 is bled off.
Wherein, for be applicable to working for a long time under dark moist environment, guide rod 7 and the magnetic ball float 8 of liquid level sensor are selected stainless steel material, and electrically operated valve uses brass material, and adhesive tape adopts elastomeric material.
The course of work: apparatus installation is fixed under dam infiltration hole, and discharge orifice just pushes up uncovered 2 to instrument.Measure after instruction when control circuit sends, often open electrically operated valve 12 and close, water delivering orifice is truncated, and rustless steel container 1 catchments.In the time that water level in container arrives lowermost the first switch triggering point of liquid level sensor, switch is triggered, and sends timing sign on to control circuit; In the time that water level in container arrives second switch triggering point of liquid level sensor, END instruction while sending little volumometer to control circuit; In the time that water level in container arrives the 3rd switch triggering point of liquid level sensor, END instruction while sending large volumometer to control circuit; In the time that the interior water level of rustless steel container 1 arrives the 4th switch triggering point of liquid level sensor, send electrically operated valve to control circuit and open imperative instruction, instrument is got back to virgin state, waits for next time and measures instruction.
During this time, if first switch triggering point is not triggered for a long time, control circuit is opened triggering electrically operated valve 12, complete this measure, and in control circuit reservoir writing time infinity.
During this time, END instruction when second switch triggering of transmission put little volumometer, if timing time is longer, control circuit is opened triggering electrically operated valve 12, completes the surveying work within the scope of low discharge one time, records actual inlet time in control circuit reservoir.If timing time is shorter, in order to improve the measuring accuracy of instrument, measure and will proceed, until the 3rd switching point is triggered, in control circuit reservoir, record actual inlet time.
