Technical field
The utility model relates to a kind of oil derrick monitoring stress sensing meter.
Background technology
To the detection of oil derrick intensity, what adopt at present is the foil gauge electricity side method that the petroleum industry standard recommendation is used.Advantages such as that this method has is highly sensitive, frequency response is good, but self some limitation are also arranged,, foil gauge higher as early-stage preparations complexity, the disposable use of foil gauge, cost such as can't use at shortcoming under inclement weather such as moist and overcast and rainy.
The utility model content
In view of this, the utility model provides a kind of oil derrick monitoring stress sensing meter, and it is simple in structure, can reuse, and can be applicable to various inclement weathers.
The stress sensing meter is used in a kind of oil derrick monitoring that the utility model provides, and comprising: sensor cavity, the erection support and the foil gauge of fixedlying connected with this sensor cavity,
The sensor cavity surface has the groove that loads this foil gauge, and described erection support and oil derrick fit tightly.
Preferably.Described foil gauge is fixed in this groove by the colloid that is filled in this groove.
Preferably, described foil gauge is included in wherein by described colloid.
Preferably, comprise two erection supports,
Each erection support comprises support of fitting with oil derrick and the screw that is threaded with this support, and screw is fixedlyed connected with this sensor cavity from the both sides up and down of described sensor cavity respectively with support.
Preferably, the both sides of described sensor cavity have a through hole respectively, and the screw of two erection supports is threaded with corresponding support by a through hole respectively.
Preferably, described erection support fits tightly by means of spot welds or bonding and oil derrick.
As seen from the above technical solution; in the utility model; use the container of sensor cavity as the bearing strain sheet; and utilize fixedly foil gauge of colloid, not only realize detecting or monitoring the stressing conditions of oil derrick, and can protect foil gauge and realize reusing of foil gauge by the Stress Transfer relation; has the adaptation field environment; be not subjected to the advantage of weather restriction, and sensing gauge can dismantle periodic verification, thereby guarantee the reliability of data.
Description of drawings
Fig. 1 is the exploded view of oil derrick monitoring of the present utility model with the stress sensing meter.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
In the utility model; use the container of sensor cavity as the bearing strain sheet; and utilize fixedly foil gauge of colloid, not only realize detecting or monitoring the stressing conditions of oil derrick, and can protect foil gauge and realize reusing of foil gauge by the Stress Transfer relation.
As shown in Figure 1, the oil derrick monitoring that provides of the utility model comprises with the stress sensing meter: sensor cavity 101, the erection support 102 and the foil gauge (not shown) of fixedlying connected with this sensor cavity 101.Wherein, sensor cavity 101 surfaces have the groove 103 that loads foil gauge, and erection support 102 fits tightly with oil derrick.
Traditional foil gauge directly is mounted on oil derrick, not only be subjected to the influence of weather conditions easily, and when dismounting, will inevitably cause the damage of foil gauge or the detection performance of failure strain sheet, therefore stress sensing meter of the present utility model is provided with the sensor cavity that is used to load foil gauge, foil gauge is installed in the groove of sensor cavity, sensor cavity and oil derrick fit tightly, and utilize the Stress Transfer relation to realize detection or the monitoring of foil gauge to the stressing conditions of oil derrick.
Further, in order to guarantee the accuracy by the stress data of sensor cavity transmission, foil gauge is fixed in this groove 103 by the colloids that are filled in this groove 103.Preferably, foil gauge is wrapped in wherein by colloid, and promptly foil gauge is built in the colloid, and all there is the protection of colloid its top, below, are fixed in the groove 103 by colloid then.
Utilize the characteristic of the material of colloid own; it can be fitted fully with sensor cavity 101, foil gauge; and will be passed to foil gauge fully by the stress that sensor cavity 101 transmits; and its outside at foil gauge can protect foil gauge not to be subjected to the influence of external environment; not only can play rainproof antirust, improve the foil gauge effect in serviceable life, and can guarantee the measuring accuracy of foil gauge.
Preferably, as shown in Figure 1, pressure sensing meter of the present utility model comprises two erection supports 102, each erection support 102 comprises support 201 of fitting with oil derrick and the screw 202 that is threaded with this support 201, and screw 202 is fixedlyed connected with this sensor cavity 101 both sides up and down of autobiography sensor cavity 101 respectively with support 201.
Preferably, the both sides of sensor cavity 101 screw 202 that has 203, two erection supports 102 of a through hole respectively is threaded with corresponding support 201 by a through hole 203 respectively.
As seen from the above technical solution; in the utility model; use the container of sensor cavity as the bearing strain sheet; and utilize fixedly foil gauge of colloid; not only realize detecting or monitoring the stressing conditions of oil derrick, and can protect foil gauge and realize reusing of foil gauge by the Stress Transfer relation.
Stress sensing meter of the present utility model has taked erection support to fixedly connected with oil derrick, support adopts the mode that is threaded with the sensor cavity, not only realized the detachable of sensing gauge, and sensing gauge is connected with oil derrick closely, guaranteed the accuracy of data
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
