Summary of the invention
The utility model is short at the time of fire alarming that exists in the prior art, the deficiency that alert locations can't be regulated, travel switch is malfunctioning can occur after long-term the use, provides a kind of durable in use, safe and reliable, and the long drilling fluid liquid level monitoring instrument of time of fire alarming.
In order to overcome above-mentioned technical problem, the utility model is solved by following technical proposals:
Drilling fluid liquid level monitoring instrument, comprise the liquid level pointer, the scale wall, cloche, fly rod, ball float, liquid level pointer connecting rod, outer wall, backstay, alarm, the ball float fixture, the liquid level pointer is connected with liquid level pointer connecting rod, the strip through-hole that liquid level pointer connecting rod passes on the backstay is fixed the position of its horizontal direction, fly rod is connected with liquid level pointer connecting rod, the outer wall inboard is provided with near the switch mount pad, near switch be connected near the switch mount pad, be connected with alarm by lead near switch, be provided with the setting pointer near switch, sensing chip is connected with the sensing chip connecting rod, and the sensing chip connecting rod is connected with liquid level pointer connecting rod.
This drilling fluid liquid level monitoring instrument is used near switch and is substituted common travel switch, having solved traditional drilling fluid liquid level monitoring instrument uses for a long time, the aging disconnection of cotton cord causes regulating alert locations, travel switch is malfunctioning, thereby the problem that can't accurately report to the police, make that drilling fluid liquid level monitoring instrument is durable in use, safe and reliable.Simultaneously, this drilling fluid liquid level monitoring instrument has also prolonged time of fire alarming, has improved the safety of drillng operation greatly.
Above-mentionedly be provided with strip through-hole near the switch mount pad, pass strip through-hole near switch, and move up and down along strip through-hole and to adjust the position, near switch be provided with nut and and cap, and along near switch shaft to screwing, will be fixed near on the switch mount pad near switch.
Being provided with that strip through-hole makes can be near the cofree up-down adjustment alert locations of switch base, to satisfy different operating environment needs near switch.
One on above-mentioned setting pointer is circular, and ring set is near switch, and the other end is the pointer shape, the indication alert locations.
To set the pointer ring set near switch, utilize near the nut on the switch and and cap be fixed, can make its dismounting and assemble convenient, can change flexibly as the case may be damage near switch or set pointer.
Above-mentioned setting pointer and near being provided with a ring set between the switch mount pad near the packing ring on the switch.
Packing ring is set prevents that nut and cap from becoming flexible.
Above-mentioned packing ring is the irony elastic washer.
The irony elastic washer is compared with general packing ring has the more outstanding effect that nut and cap become flexible that prevents, and more durable.
The utility model is used near switch and is substituted common travel switch, having solved traditional drilling fluid liquid level monitoring instrument uses for a long time, the aging disconnection of cotton cord causes regulating alert locations, travel switch is malfunctioning, thereby the problem that can't accurately report to the police, make that drilling fluid liquid level monitoring instrument is more durable in use, safe and reliable.Simultaneously, the utility model has also prolonged time of fire alarming, has improved the safety of drillng operation greatly.
