Description

Technical Field

[0001] The utility model relates to the field of pressure-sensitive sensor components, in particular to a protective pressure-sensitive sensor component. Background Art

[0002] Pressure sensor is a broader term that refers to sensors made with piezoresistors or other pressure-sensitive elements to detect or measure physical quantities such as pressure, force or strain. Therefore, pressure sensors can include pressure sensors, but also other types of sensors. Pressure sensors are a specific type of pressure-sensitive sensor that is specifically designed to detect or measure pressure. They usually use piezoresistors or other pressure-sensitive technologies to achieve this purpose.

[0003] Some pressure sensors are installed on pipes. However, since the insertion end of the sensor is connected to the pipe thread, the connection is usually relatively fragile. If it is hit or used for a long time, it may cause leakage, thereby reducing the safety of use.

[0004] In order to solve the above problems, a protective pressure-sensitive sensor component is proposed in the present application. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes a protective pressure-sensitive sensor component. The utility model is provided with a protective shell to protect the connection between the pipeline and the sensor, thereby reducing leakage in case of leakage. At the same time, under the action of the integrated cabinet response mechanism, a reminder is given in case of leakage, thereby increasing the safety of use.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides a protective pressure-sensitive sensor assembly, including a pipe and a sensor threadedly sleeved on the pipe, wherein a detachable protective shell is connected between the pipe and the sensor insertion position;

[0009] A communication response mechanism is provided between the protective shell and the pipeline, and the communication response mechanism is used for responding when the sensor insertion end leaks.

[0010] Preferably, the connection response mechanism includes a liquid inlet pipe, a rotating box, a right-angle tube and an entry pipe, one end of the liquid inlet pipe is fixedly connected to the protective shell, the other end of the liquid inlet pipe is rotationally connected to the rotating box through a rotating joint, the side of the rotating box away from the liquid inlet pipe is connected to the liquid inlet end of the right-angle tube through a rotating joint, the liquid outlet end of the right-angle tube is connected to the entry pipe through a rotating joint, the entry pipe is threadedly connected to the pipeline, axial flow fan blades are fixedly installed inside the rotating box, a wind digging shell is fixedly installed on the periphery of the rotating box, and a whistle is fixedly connected to the wind digging shell.

[0011] Preferably, the rotary box is a rubber rotary box.

[0012] Preferably, the sides of the protective shell are fixedly mounted with connecting strips, and the connecting strips are threadedly sleeved with fastening bolts.

[0013] Preferably, a rubber belt is fixedly installed at the joint between the protective shell, the pipeline and the sensor sleeve.

[0014] The above technical solution of the utility model has the following beneficial technical effects:

[0015] Under the action of the protective shell, the connection between the pipeline and the sensor is protected. When the connection leaks, the protective shell plays a protective blocking role. The leaked liquid inside the protective shell can enter the interior of the rotating box through the liquid inlet pipe and act on the axial flow fan blades. The axial flow fan blades drive the rotating box to rotate, causing the digging shell to rotate, and air enters the interior of the digging shell and enters the interior of the whistle. Under the action of the whistle, it plays a ringing role, which plays an auxiliary reminder role, reminds of leakage, and increases the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1-3 As shown, the utility model proposes a protective pressure-sensitive sensor assembly, comprising a pipe 1 and a sensor 2 threadedly sleeved on the pipe 1, and a detachable protective shell 3 is connected between the pipe 1 and the sensor 2 at the insertion point;

[0022] A communication response mechanism 4 is provided between the protective shell 3 and the pipeline 1 , and the communication response mechanism 4 is used for responding when the insertion end of the sensor 2 leaks.

[0023] In an optional embodiment, the connection response mechanism 4 includes a liquid inlet pipe 41, a rotating box 42, a right-angle tube 43 and an entry pipe 44. One end of the liquid inlet pipe 41 is fixedly connected to the protective shell 3, and the other end of the liquid inlet pipe 41 is rotatably connected to the rotating box 42 through a rotating joint. The side of the rotating box 42 away from the liquid inlet pipe 41 is connected to the liquid inlet end of the right-angle tube 43 through a rotating joint, and the liquid outlet end of the right-angle tube 43 is connected to the entry pipe 44 through a rotating joint. The entry pipe 44 is threadedly connected to the pipeline 1, and an axial flow fan blade 45 is fixedly installed inside the rotating box 42, and a wind digging shell 46 is fixedly installed on the outer periphery of the rotating box 42. A whistle 47 is fixedly connected to the wind digging shell 46.

[0024] Furthermore, the rotary box 42 is a rubber rotary box.

[0025] It should be noted that a one-way valve is provided on the right-angle tube 43 so that the liquid inside the rotating box 42 can flow into the pipeline 1 in one direction.

[0026] In an optional embodiment, connecting strips 5 are fixedly mounted on the sides of the protective shell 3 , and fastening bolts 6 are threadedly sleeved on the connecting strips 5 .

[0027] It should be noted that there are two protective shells 3 , and the two protective shells 3 are symmetrically arranged, and the two protective shells 3 form a complete circular protective shell.

[0028] In an optional embodiment, a rubber belt is fixedly installed at the joint between the protective shell 3, the pipeline 1 and the sensor 2.

[0029] It should be noted that the sealing performance is increased under the action of the rubber belt.

[0030] In the utility model, under the action of the protective shell 3, the connection between the pipeline 1 and the sensor 2 is protected. When the connection leaks, the protective shell 3 plays a protective blocking role. The liquid leaked from the protective shell 3 can enter the interior of the rotating box 42 through the liquid inlet pipe 41, and act on the axial flow fan blades 45. The axial flow fan blades 45 drive the rotating box 42 to rotate, so that the digging shell 46 rotates, and air enters the interior of the digging shell 46 and enters the interior of the whistle 47. Under the action of the whistle 47, it plays a ringing role, so as to play an auxiliary reminder role, remind leakage, and increase the safety of use.
