The beneficial effects of the utility model are: the magnetic pull in the utility model between magnet steel weight and the magnetic conduction steel base, conduct to the top support by stainless steel wire rope, make stainless steel wire rope be subjected to the pulling force that both direction is opposite and numerical value is identical in two ends up and down, pressure transducer with the stainless steel wire rope binding, after stainless steel wire rope is tightened up, even also can not shake or move in the more violent place of SEA LEVEL VARIATION, thereby effectively avoid the damage of pressure transducer, and guarantee the reliable of measured value.
Description of drawings
Fig. 1 is a front view of the present utility model.
Embodiment
As shown in Figure 1, present embodiment has the secondary device 1 that is installed on the support 2 (in this area, primary equipment refers to the equipment that sensor etc. is used for Information Monitoring, secondary device then is meant conversion of signals, equipment such as transmitting device and Displaying Meter), the pressure measurement sleeve pipe 4 of the fixedly connected vertical layout in support 2 belows, the pressure transducer of being located in the pressure measurement sleeve pipe 45 is electrically connected with secondary device 1 by signal cable 3, be characterized in being provided with in the described pressure measurement sleeve pipe 4 stainless steel wire rope 6 that the upper end is connected with support 2, adopt stainless steel bolt to fix in this example between stainless steel wire rope 6 and the support 2, the elasticity of stainless steel wire rope 6 is with loose being advisable not.Described stainless steel wire rope 6 lower ends connect and bind with pressure transducer 5 and magnet steel weight 8 from top to bottom successively, pressure measurement sleeve pipe 4 inwalls are near bottom fixed installation and magnet steel weight 8 corresponding magnetic conduction steel bases 9, for the foreign material that guarantee to enter in the pressure measurement sleeve pipe 4 can be discharged from blow-off pipe 10, adopt the spot welding mode to weld between magnetic conduction steel base 9 and the pressure measurement sleeve pipe 4 or pass through screw retention, except pad or screw retention point, other local all and the gap of leaving 2-3cm between the pressure measurement sleeve pipe 4 in order to blowdown.Magnetic pull that magnet steel weight 8 and magnetic conduction steel base are 9 must be suitably, do not surged or the variation of water level and shake or move and be advisable with pressure transducer 5.Whether magnetic pull is suitable, can test by means of the weight beam of standard.Surge or place that SEA LEVEL VARIATION is more violent, required magnetic pull is corresponding wants big (as 100N); Surge or place that SEA LEVEL VARIATION is not too violent, required magnetic pull is corresponding can littler (as 50N).
In order to prevent when the folding and unfolding magnet steel weight 8 and pressure measurement sleeve pipe 4 adsorbs, guide frame 7 (non-magnet material making) is installed on magnet steel weight 8, this guide frame diameter is greater than the diameter of magnet steel weight 8 but less than the internal diameter of pressure measurement sleeve pipe 4.
By mode of being fastened or the binding of plastic cable strapping fixed form, realize synchronous folding and unfolding between described signal cable 3 and the stainless steel wire rope 6.
Blow-off pipe 10 is offered in described pressure measurement sleeve pipe 4 bottoms, enters foreign material in the pressure measurement sleeve pipe 4 with discharge.
Offer pressure guiding pipe 11 on the described pressure measurement sleeve pipe 4.
The principle of work of present embodiment is: the magnetic force between magnet steel weight 8 and the magnetic conduction steel base 9, conduct to top support 2 by stainless steel wire rope 6, make stainless steel wire rope 6 under the effect of magnetic force, be tightened up, and because pressure transducer 5 and stainless steel wire rope 6 bindings, even therefore pressure transducer 5 also can not shake in the more violent place of SEA LEVEL VARIATION or move, thereby guarantee the reliable of measured value.
