Description
Technical field
The utility model relate to a kind of detect seepage in top cover catchment change device, especially a kind of Hydropower Unit top cover water level signal device be convenient for measuring.
Background technology
Top cover water level signal device is the important Element of automatic control of Hydropower Unit top cover drainage system controlling unit.Generally speaking; top cover water level signal device is arranged in Hydropower Unit top cover; in main detection top cover, seepage is catchmented change; realize sending control signal (make and break contact setting control) when top cover water level rises or drops to relevant position; automatic start-stop head cover drainage pump, and then protection Hydropower Unit is normally run.
Because Hydropower Unit type is diversified in specifications, the make and break contact that existing top cover water level signal device is arranged is inconsistent.When carrying out top cover drainage system maintenance of equipment or components and parts are patrolled and examined, needing the top cover water level definite value according to arranging to check signalling means, now needing to be equipped with rule to carry out check work; Meanwhile, due to narrow space, poor visibility in unit top cover, be difficult to when checking work ensure rule needs and top cover plane perpendicular, the accuracy of top cover water level signal device check will certainly be had influence on, and then affect Hydropower Unit top cover drainage system and normally work.
The function that top cover water level signal device only has top cover water level switch to control, but top cover water level switch contact, rule are separate, increase unnecessary trouble to the maintenance of equipment of maintainer, the work of patrolling and examining.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Hydropower Unit top cover water level signal device be convenient for measuring, and can solve and check difficult problem, not need to carry rule, construct novel, practical, be convenient to popularization.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Hydropower Unit top cover water level signal device be convenient for measuring, comprise the mounting plate being fixedly installed in top cover bottom surface, mounting plate is vertically provided with top cover level measuring conduit, measuring guide body with a scale is provided with in top cover level measuring conduit, the outer surface of top cover level measuring conduit has water insoluble, oil bloom coating, top cover level measuring conduit is provided with multiple make and break contact, magnetic float to be sheathed on top cover level measuring conduit and to be slidably connected with top cover level measuring conduit, top cover level measuring conduit top is provided with mounting flange and electrical junction box.
The long 500-1000 millimeter of measuring guide body with a scale.
The minimum scale value of scale is 10 millimeters.
The quantity of make and break contact is two, is respectively make and break contact and second switch contact for the first time.
A kind of Hydropower Unit top cover water level signal device be convenient for measuring that the utility model provides, the effect of rule is played by measuring guide body, because measuring guide is installed perpendicular to cap base, check for top cover water level signal device make and break contact and reference value is accurately provided, improve Hydropower Unit top cover water level plant maintenance work efficiency; Meanwhile, top cover level measuring conduit is coated with water insoluble, oil bloom coating, at the Hydropower Unit top cover place that visibility poor, ambient light are dim, is convenient to find, location top cover water level signal device; Can solve and check difficult problem, not need to carry rule, construct novel, practical, be convenient to popularization.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of Hydropower Unit top cover water level signal device be convenient for measuring, comprise the mounting plate 7 being fixedly installed in top cover bottom surface 8, mounting plate 7 is vertically provided with top cover level measuring conduit 4, the measuring guide body 4-2 of 4-1 with a scale is provided with in top cover level measuring conduit 4, the outer surface of top cover level measuring conduit 4 has water insoluble, oil bloom coating, top cover level measuring conduit 4 is provided with multiple make and break contact, magnetic float 6 to be sheathed on top cover level measuring conduit 4 and to be slidably connected with top cover level measuring conduit 4, top cover level measuring conduit 4 top is provided with mounting flange 2 and electrical junction box 1.
The long 500-1000 millimeter of measuring guide body 4-2 of 4-1 with a scale.
The zero graduation of the scale mark of measuring guide body 4-2 is positioned at the bottom end of top cover level measuring catheter body, the minimum scale value of scale 4-1 is 10 millimeters, carry out top cover water level signal device make and break contact check work to facilitate, improve Hydropower Unit top cover water level plant maintenance work efficiency.
The quantity of make and break contact is two, is respectively make and break contact 3 and second switch contact 5 for the first time.
During utility model works, magnetic float 6 rises along with the change of the water surface or declines, with permanent magnet ring on magnetic float 6, the make and break contact made on top cover level measuring conduit 4 is connected by the magnetic force of magnet ring, and then make top cover high water stage or the action of low-water level signal relay in power station, start or stop head cover drainage pump.
Played the effect of rule by measuring guide body, because measuring guide is installed perpendicular to cap base, check for top cover water level signal device make and break contact and reference value is accurately provided, improve Hydropower Unit top cover water level plant maintenance work efficiency; Meanwhile, top cover level measuring conduit is coated with water insoluble, oil bloom coating, at the Hydropower Unit top cover place that visibility poor, ambient light are dim, is convenient to find, location top cover water level signal device; Can solve and check difficult problem, not need to carry rule, construct novel, practical, be convenient to popularization.
