The utility model is characterized in that the fixing shelf is provided with a straight pipe type potentiometer; the top end of the tappet is provided with the sliding contact of the straight pipe type potentiometer; the tappet is connected with the float; a guiding device is arranged between the tappet and the straight pipe type potentiometer; the guiding device is provided with a cross beam which crosses over an open channel so that the fixing shelf can be installed. The utility model has the advantages of simple structure, easy manufacture, low price, easy use, stable and reliable output signals, and long service life.
Description
The utility model is the measuring apparatus about fluid flow, especially for the measuring apparatus of measuring the discharge of sewage.
Generally adopt both at home and abroad at present to change and measure fluid flow, particularly measure the flow of sewage according to liquid level in the formula open channel of weir.Use the measurement mechanism of this principle that all kinds and style are arranged, it is the most popular wherein to reflect that with float liquid level changes, as float mechanical type measuring apparatus and float condenser type measuring apparatus.Float mechanical type measuring apparatus is made up of float, tappet, mechanical type record mechanism and frame.Mechanical type integrating mechanism will be undertaken obtaining flow after the computation of table lookup by the record on the record paper in the back through certain hour through liquid level change record that float and tappet send on record paper at interval.The float condenser type measuring apparatus then condenser network by a complexity will be converted to electric signal earlier through the liquid level change that float and tappet transmit, and then this electric signal be imported respectively that the electronics integrator adds up integrating, the input electronic console carries out the demonstration of instantaneous value and integrating value.The defective ， And that float condenser type measuring apparatus has been removed artificial integrating from can show instantaneous flow, and can electric signal be carried at a distance practical operated from a distance by lead.But its condenser network is complicated, makes inconvenience, cost is high.
The purpose of this utility model is to be to provide a kind of weir formula open-ditch sewage flowmeter that comprises float, tappet, electronics integrator and display circuit with simple dynamoelectric signal conversion equipment.
The purpose of this utility model is this realization: a kind of weir formula open-ditch sewage flowmeter that comprises float, tappet, fixed mount, electronics integrator, electronic console, it is characterized in that fixed mount is provided with the straight pipe type potentiometer, the tappet top that links to each other with float is provided with the sliding contact of straight pipe type potentiometer, be provided with guide piece between tappet and the straight pipe type potentiometer, be provided with on the open channel crossbeam with mounting and fixing support.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is a kind of guide piece structural representation of the present utility model.
Fig. 3 is a voussoir level(l)ing mechanism front elevation.
Fig. 4 is the top view of Fig. 3.
The flow digital display device 15 that the utility model comprises float 1, tappet 2, fixed mount 13 as shown in Figure 1 and is made of electronics integrator and electronic console.Fixed mount 13 is provided with straight pipe type potentiometer 10.Tappet 2 one ends link to each other with float 1, and its other end is provided with the sliding contact 11 of straight pipe type potentiometer 10.Fixed mount 13 below screws 8 are provided with the guide frame 3 that comprises orienting sleeve 4.Tappet 2 passes orienting sleeve 4.The below of tappet 2 middle parts and close float 1 is respectively arranged with convex shoulder 5 and 18.Convex shoulder 5 is positioned at orienting sleeve 4 tops, and convex shoulder 18 is positioned at orienting sleeve 4 belows, and they control the extreme lower position and the extreme higher position of float 1 respectively.Fixed mount 13 usefulness screws 7 are fixed on the crossbeam 6.Crossbeam 6 is across on the canal wall of open channel 16 both sides.Straight pipe type potentiometer 10 forms with flow digital display device 15 by cable 14 and is electrically connected.Flow digital display device 15 uses that MCS-51 type chip microprocessors are sampled, computing and integrating are handled, and shows instantaneous deliveries and accumulates flow with four LED charactrons and six message registers respectively again.Weir plate 17 is arranged near crossbeam 6 downstreams.When the sewage in the open channel 16 is subjected to the throttling of weir plate 17 and produces liquid level change, float 1 lifting with liquid level change.Tappet 2 moves up and down with float together with 11 of armature contacts, then straight pipe type potentiometer 10 outputs and the corresponding dc current signal of this liquid level.Above-mentioned dc current signal is through cable 14 input flow rate digital display devices 15, carry out data processing by MCS-51 type chip microprocessor after, show sewage instantaneous deliveries in the open channel with four LED charactrons respectively, show with six message registers to accumulate flows.Also be provided with protective cover 9 on the fixed mount 13.Protective cover 9 is with cappings such as straight pipe type potentiometer 10, power connection, terminal block (not shown)s.Crossbeam 6 should keep level with the joint face of fixed mount 13, makes straight pipe type potentiometer 10 be in plumbness, in order to moving up and down of float 1, tappet 2 and sliding contact 11.Crossbeam 6 two ends and Qu Bi junction, open channel 16 both sides can also be provided with four groups of level(l)ing mechanisms that comprise bolt and nut.Screw rod is embedded in Qu Bishang, and its extension passes the fixed orifice of beam-end.Be positioned at the both sides that two nuts on the screw rod lay respectively at the said fixing hole, crossbeam is fixed on required height.Crossbeam 6 two ends also can be provided with four groups of voussoir level(l)ing mechanisms (claiming the screw parallels again, referring to Fig. 3) by the screw rod location.The voussoir level(l)ing mechanism comprises that to hold one to one to the plane other end be the parallels 24 and 23 on inclined-plane, and adjusting screw 22.Adjusting screw 22 make parallels 24 and 23 vertically x-x move (see figure 4), to adjust the level of crossbeam 6.Parallels 24 and 23 is provided with peristome 25.The set bolt that is embedded on the canal wall penetrates in the fixed orifice of crossbeam 6 by peristome 25, fixes with nut.
The utility model except that above-mentioned orienting sleeve 4 and guide frame 3 as the guide piece, armature contact 11 places also can be set on tappet 2 tops be provided with as shown in Figure 2 orienting lug 19.Angle 20 and center mounting hole 21 ， And that orienting lug 19 has four evaginations have certain thickness.Angle 20 is complementary with four angles of straight pipe type potentiometer 10 inwalls.Orienting lug 19 is inserted in tappet 2 backs with its center mounting hole 21 to be fixed.
The utlity model has simple and reliable for structurely, easy to use, stable output signal shows correctly, and price is low, the advantage that the life-span is long.
