Problems solved by technology
[0004] Judging from the structure of the existing oil field angular displacement sensor, there are generally the following problems: its structure is relatively complicated, which is not conducive to disassembly and maintenance, and it is mostly made of metal, which is heavy in weight. On the outside, the relevant parts of the joint part need to be added between the antenna and the housing, which not only is troublesome to assemble and affects the waterproof performance, but also takes up a lot of space, and the antenna is easy to be damaged during transportation. In addition, the overall fixing effect of the sensor is not very good

Embodiment Construction
[0011] The implementation of the present invention is described in detail below in conjunction with accompanying drawing:
[0012] The fixed bottom plate of the housing is provided with four holes of a specific size, allowing four powerful magnets to be embedded in it, the sensor housing and the fixed bottom plate are fixed by bolts, and the four magnets are pressed tightly in it, so that This enables a fixed part of the housing bottom. The circuit board is fixed inside the shell by bolts, and then a specially designed fixing part is used to fix the battery and the antenna. The lower part can compress the battery, and the upper part has a slot to place the antenna, and at the same time, it plays a role in both. Protective effects. Finally, the upper cover is installed so that the inside of the housing is in a sealed state.
[0013] as attached figure 1 , 2 As shown, a device for a wireless angular displacement sensor includes a fixed base plate 1, a housing 3, and a housin...

The invention discloses a wireless angular displacement sensor device, which comprises a fixing bottom plate, a housing and a housing upper cover. Four hole slots are disposed in the fixing bottom plate, and accommodate powerful magnets respectively. The housing and the fixing bottom plate are fastened together via four bottom plate fixing bolts. The four powerful magnets are pressed tightly in the hole slots. One side inside the housing is fixed with a circuit board through screws, and the other side is fixed with batteries. The upper portion of the batteries in the housing is provided with a fixing member for fastening the batteries in the housing. The housing is fixedly connected with the housing upper cover through upper cover fixing bolts. An antenna fixing groove is disposed in the fixing member. An antenna is fixedly disposed in the fixing groove. According to the invention, the wireless angular displacement sensor device is compact in layout, simple in structure, and easy to assemble, disassemble and maintain; has good waterproof performance as the exterior is provided with the antenna and a connector; is small in size, light in weight and thus easy to carry and install; and is reliable and stable in fixing so that the sensor is more accurate in dip angle measurement.
Description
technical field [0001] The invention relates to a device of a wireless angular displacement sensor, in particular to a shell structure of an angular displacement sensor designed for a beam pumping unit in the oil field. Background technique [0002] With the rapid development of my country's social economy and science and technology, in recent years, the oilfield industry has developed rapidly, especially the construction of digital oilfields, which has become more and more recognized and popularized. The wireless angular displacement sensor is a digital oilfield-specific sensor designed for the monitoring of the dynamometer diagram of the beam pumping unit, and has been widely used in digital oilfield construction. [0003] At present, the oilfield angular displacement sensor is installed directly on the top of the beam of the pumping unit in a completely open-air environment, so it has to withstand harsh working environments such as rain, snow, dust, and sandstorms. In ord...
