Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular, to a sensor core wire tensile strength storage device. Background Technology

[0002] A sensor is a detection device that can sense physical or chemical quantities such as temperature, pressure, and light, and convert them into electrical signals. It consists of sensing elements, conversion elements, etc., and features miniaturization and intelligence. It is widely used in industries, medical fields, and construction engineering, and is known as the "electric senses" of modern technology.

[0003] For example, differential pressure hydrostatic levels involve the use of sensors. A differential pressure hydrostatic level is a device used to monitor the relative settlement of multiple points, that is, the change in the vertical displacement of each measuring point relative to a reference point. This allows for the accurate calculation of the relative settlement at each measuring point, and by measuring the change in liquid level at the measuring point, the positional change of the measuring point can be determined. Its working principle is as follows: after liquid is injected into a U-shaped tube open at both ends to the atmosphere, the liquid, under the influence of atmospheric pressure and gravity, will eventually remain at the same horizontal level.

[0004] Its settlement system consists of at least two sensors connected by test leads. When a differential pressure hydrostatic level is used for roadbed settlement measurement, the settlement system needs to be buried in the roadbed. However, due to construction factors, the roadbed is often compacted by construction machinery, which can lead to uneven deformation of the roadbed and consequently, the test leads may break under tension. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sensor core wire tensile strength storage device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A sensor core wire tensile strength storage device includes a storage box attached to the end of a sensor, one end of the storage box having an inlet and the other end having an outlet, and the storage box having a receiving cavity for accommodating stacked sensor core wires.

[0008] Preferably, a winding tongue is provided inside the receiving cavity, and the stacked sensor core wires are wound around the winding tongue.

[0009] Preferably, the winding tongue is adapted to extend between the inlet and the outlet.

[0010] Preferably, a connection port is provided on the side wall of the winding tongue, and the inlet is connected to the connection port.

[0011] Preferably, the end of the wire storage box is detachably connected to a connecting end, and the winding tongue and the wire inlet are both disposed on the connecting end.

[0012] Preferably, the winding tongue and the connecting end are integrally formed.

[0013] Preferably, the end of the cable storage box is detachably connected to a cable conduit connector, and the cable outlet is located on the cable conduit connector.

[0014] Preferably, the connecting end has a mating surface on the side opposite to the cable storage box, and the mating surface is provided with an annular groove for engaging the sealing ring.

[0015] Preferably, the sidewall of the winding tongue is adapted to have an incline, and the cross-sectional area of ​​the winding tongue gradually decreases from the inlet side to the outlet side.

[0016] Preferably, the cable storage box is cylindrical, and the end of the cable connector is constructed with a column for fitting the cable storage box, and the side wall of the column is provided with an annular groove for inserting a sealing ring.

[0017] The beneficial effect of this utility model is that a portion of the sensor core wire is pre-stored in a stacked manner in the wire storage box. When the core wire is subjected to abnormal pulling, the core wire in the wire storage box will extend out of the box, thereby preventing the sensor core wire from being stretched and broken.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 As shown, a sensor core wire tensile strength storage device includes a storage box 1 with an internal receiving cavity 4. The storage box 1 is attached to the end of the sensor, and the sensor core wire 11 can extend into the receiving cavity 4 from the inlet 2 of the storage box 1 and partially stack in the receiving cavity 4, and then extend out from the outlet 3 of the storage box 1 to connect to other components, such as another sensor.

[0022] It is conceivable that if the sensor core wire 11 is subjected to unexpected pulling at this time, the core wire 11 inside the wire storage box 1 will be pulled out of the box, thereby preventing the sensor core wire 11 from being stretched and broken.

[0023] In some embodiments, the wire storage device of this utility model consists of a connecting end 7, a wire storage box 1, and a wire conduit connector 8 connected in sequence. The connecting end 7 and the wire conduit connector 8 are respectively provided with a wire inlet 2 and a wire outlet 3. The connecting end 7 is used to connect to the end of the sensor, and the wire conduit connector 8 is used to connect to, for example, the vent pipe (not shown) of a differential pressure hydrostatic level, that is, the core wire 11 passing through the wire storage box 1 can be arranged inside the vent pipe.

[0024] Overall, the cable storage device is cylindrical, meaning the cable storage box 1 is tubular. Each of the connecting ends 7 and the conduit connector 8 has a corresponding column 10, with both ends of the cable storage box 1 fitted onto the two columns 10. Furthermore, the side walls of both columns 10 are constructed with annular grooves, which can be used to insert sealing rings, thereby ensuring a relative seal of the cable storage box 1 and guaranteeing the airtightness of the receiving cavity 4.

[0025] Among them, the side of the connecting end 7 away from the wire storage box 1 is specifically constructed with a fitting surface 9, which can be fitted with the end of the sensor through the fitting surface 9, and the fitting surface 9 is also provided with an annular groove for inserting the sealing ring.

[0026] In a preferred embodiment, a winding tongue 5 is also constructed on the end of the connecting end 7 facing the conduit connector 8. For example, the winding tongue 5 can be integrally formed with the connecting end 7, thereby facilitating manufacturing by means of machining methods such as lathes. The stacked portion of the aforementioned sensor core wire 11 is wound around the side wall of the winding tongue 5. Since in this preferred embodiment, the winding tongue 5 extends between the inlet 2 and the outlet 3, the winding tongue 5 will also have an additional guiding function for the core wire 11 as it is exposed from the wire storage box 1.

[0027] In other possible examples, the wire storage device may not be cylindrical, and the winding tongue 5 may be arranged in other directions, such as vertically (not shown). In this case, the winding tongue 5 may also be adapted to have rotational freedom so that the core wire 11 wound on it can be more easily exposed by rotation.

[0028] See also Figure 1In this example, a connection port 6 can also be provided on the side wall of the winding tongue 5, and the connection port 6 is connected to the inlet port 2. Thus, the inlet port 2 and the winding tongue 5 can have substantially the same axis, and the sensor core wire 11 can extend from the inlet port 2, then pass through the connection port 6 into the receiving cavity 4 and be wound around the winding tongue 5. It can be understood that the coaxial arrangement of the inlet port 2 and the winding tongue 5 improves the structural compactness of the wire storage device, for example, facilitating the placement of the sensor below the roadbed, as it is less likely to cause interference with other components or occupy space.

[0029] In a preferred example, the sidewall of the winding tongue 5 is adapted to have a slope, and based on this slope, the cross-sectional area of ​​the winding tongue 5 gradually decreases from the inlet 2 side to the outlet 3 side. It is understood that in order to allow the core wire 11 to be extended at the inlet 2, the core wire 11 needs a certain amount of space to unfold when it detaches from the winding post; otherwise, the core wire 11 may not easily detach smoothly. In this example, the space defined between the winding tongue 5 and the wire storage box 1 increases precisely at the outlet 3, which makes the unfolding of the core wire 11 smoother and correspondingly improves the reliability of the wire storage device.

[0030] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
