Description
Technical Field
The utility model relates to a stress sensor technical field, specific water pressure compensation formula underground works stress sensor that says so.
Background
Along with the continuous development of science and technology, the application of digitization, intellectualization and automation is gradually popularized, in industrial practice, pressure is one of important parameters in industrial production, and in order to ensure the normal operation of production, the pressure must be monitored and controlled. Cities such as water conservancy and hydropower, railway transportation, intelligent building and the like can output detected signals by means of stress sensors so as to provide external computer equipment with measurement results and experimental conclusions. When using stress sensor at the pressure of survey soil in the soil, because contain moisture in the soil, can lead to the fact certain pressure to the sensor, influence the precision that detects on the one hand, on the other hand can make the life of sensor receive the influence.
Disclosure of Invention
To the defect of above-mentioned technique, the utility model provides a water pressure compensation formula underground works stress transducer.
The utility model provides a water pressure compensation formula underground works stress transducer, includes casing, support, string wire, chuck, coil, diaphragm, water pump, flange, pipe, the inside of casing forms confined cavity structure, and the diaphragm is installed at the lower extreme of casing, and the support symmetry is installed on the diaphragm, and the both ends of string wire are fixed on corresponding support through the chuck respectively, and the coil is located the string wire directly over, and the coil is fixed on the casing, and the flange mounting is in the upper end of casing, and the water pump is linked together through the cooperation of pipe, flange and cavity structure.
The cavity structure is sealed and contains water.
The utility model discloses on traditional steel string formula sensor's basis, utilize the principle that inside and outside water pressure was offset each other, form confined cavity structure in the inside of casing to water has been held, during the actual test, can go into the cavity structure with external water pump with the pressure boost or with the water discharge in the cavity structure with the decompression, the purpose is guaranteed to equal with the pressure of soil normal water, has ensured the accuracy that detects.
The utility model has the advantages that: the utility model has the advantages of reasonable design, with the help of the principle that inside and outside water pressure was offset each other to avoided soil water pressure to apply and caused the influence to stress sensor's detection on stress sensor, guaranteed the accuracy that detects.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, and the utility model is further explained below.
As shown in figure 1, the water pressure compensation type underground engineering stress sensor comprises a shell 1, a support 2, a steel string 3, a chuck 4, a coil 5, a diaphragm 6, a water pump 7, a flange 8 and a conduit 9, wherein a closed cavity structure 1a is formed inside the shell 1, the diaphragm 6 is installed at the lower end of the shell 1, the support 2 is symmetrically installed on the diaphragm 6, two ends of the steel string 3 are respectively fixed on the corresponding support 2 through the chuck 4, the coil 5 is positioned right above the steel string 3, the coil 5 is fixed on the shell 1, the flange 8 is installed at the upper end of the shell 1, and the water pump 7 is communicated with the cavity structure 1a through the matching of the conduit 9 and the flange 8.
The cavity structure 1a is sealed to contain water.
During the use, will the utility model discloses in the appointed soil is put into to the product, because moisture can form certain water pressure to casing 1 in the soil, drive water pump 7 this moment, go into or take out the water in cavity structure 1a with external water pump to change the pressure in cavity structure 1a, with the balance of external pressure in guaranteeing, realized the pressure measurement to soil accuracy.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and what is described in the specification are the principles of the present invention, and that there can be various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
