Technical Field

[0001] This invention relates to the field of pressure sensor technology, and more particularly to a pressure sensor. Background Technology

Pressure sensors are among the most commonly used sensors in industrial practice and are widely applied in various industrial automation environments.

[0004] The pressure sensor described above may malfunction or become inaccurate during prolonged use. However, this pressure sensor is not easy to self-test in order to deal with malfunctions or inaccurate measurements. Therefore, we propose a pressure sensor. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a pressure sensor. A drive screw rotates to drive a second gear to mesh with a first gear; a drive rod rotates, causing the second gear to rotate, which in turn drives a rotary table via a first worm gear, moving another sensor body to the detection station. Similarly, a third sensor body can be moved to the detection station. The results from the three sensor bodies are compared to see if they are within the error range. If they are, the sensor is normal; otherwise, it is abnormal. This pressure sensor facilitates self-testing to address malfunctions or inaccurate measurements.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pressure sensor includes a housing, a hexagonal end mounted on the bottom of the housing with a threaded opening, a rotating platform rotatably mounted inside the housing, a ring mounted on the rotating platform, and a clearance groove between the rotating platform and the ring; multiple fixing sleeves mounted on the ring, a sensor body mounted on the fixing sleeves, a connecting end located below the sensor body, a terminal portion located above the sensor body, a connecting platform inside the housing with a wire harness mounted on the connecting platform; an L-shaped block mounted on the housing with a flow groove inside the L-shaped block, and multiple through grooves inside the ring;

[0008] The connecting platform is equipped with a conductive mechanism, and the housing is equipped with a drive mechanism that drives the rotating platform to rotate.

[0009] The drive mechanism includes: a connecting frame mounted on the rotating platform; a first worm gear mounted on the connecting frame; a housing mounted on the shell; a first rotating rod rotatably disposed within the housing; a first worm mounted on the first rotating rod, with the first worm gear and the first worm meshing; and a drive assembly disposed within the housing.

[0010] The drive assembly includes: a fourth rotating rod rotatably disposed within the housing; a first belt connecting the fourth rotating rod and the first rotating rod via the first belt; a first gear mounted on the fourth rotating rod; a drive rod rotatably disposed within the housing; and a second gear mounted on the drive rod, with the first gear and the second gear being in corresponding positions.

[0011] The present invention also includes a cooling mechanism disposed within the housing. The cooling mechanism comprises: two rotating shafts rotatably disposed below the connecting platform; an arc-shaped heat sink mounted on the rotating shafts; a third gear mounted on the rotating shafts, with two third gears meshing; a first bevel gear mounted on one of the rotating shafts; a rotating shaft rotatably disposed within the clearance groove; and a second bevel gear mounted on the rotating shafts, with the first bevel gear and the second bevel gear meshing.

[0012] The housing is equipped with a central shaft that rotates within it. A third bevel gear is mounted on one end of the central shaft, and a fourth bevel gear is mounted on the rotating shaft. The third and fourth bevel gears mesh with each other. A second worm gear is mounted on the other end of the central shaft.

[0013] The housing contains a second rotating rod and a third rotating rod that rotate rotatably. A second worm gear is mounted on the second rotating rod, and the second worm gear meshes with the second worm wheel. A sixth gear is mounted on the third rotating rod, and the sixth gear is positioned opposite to the second gear. The second rotating rod and the third rotating rod are connected by a second belt drive.

[0014] The housing is equipped with a screw that rotates within it. A moving plate is threaded onto the screw. A second gear is rotatably mounted on the moving plate. A protrusion is installed on the drive rod. A groove is formed inside the second gear. The protrusion slides within the groove. An clearance hole is formed inside the moving plate.

[0015] The arc-shaped heat sink includes: a first arc-shaped end; a second arc-shaped end, the second arc-shaped end being mounted on the first arc-shaped end; a flow cavity is formed inside the first arc-shaped end and the second arc-shaped end, the flow cavity is provided with a rough surface, and the flow cavity is provided with coolant.

[0016] The housing has two arc-shaped grooves, the second arc-shaped end moves within the arc-shaped groove, a moving cylinder is installed on the housing, a through groove is provided inside the moving cylinder, a first magnet is installed on the housing, a second magnet is installed on the moving cylinder, and the second arc-shaped end (4022) is inserted into the through groove (1131).

[0017] Multiple conductive blocks are installed on the connecting platform. The conductive blocks are in contact with the terminal portion, and the wire harness, the conductive blocks, and the terminal portion are connected.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) The present invention drives the second gear to mesh with the first gear by rotating the drive screw; drives the drive rod to rotate and drives the second gear to rotate, and drives the rotary table to rotate through the first worm gear, thereby driving another sensor body to move to the detection station. Similarly, the third sensor body can be driven to move to the detection station. The results of the detection of the three sensor bodies are compared to see if they are within the error range. If they are within the error range, it is normal; otherwise, it is abnormal. The pressure sensor of the present invention is easy to self-test in order to deal with the situation of failure or inaccurate measurement.

[0020] (2) In this invention, the drive rod rotates to drive the second gear to rotate, which in turn drives the sixth gear and the third rotating rod to rotate. The second belt drives the second rotating rod and the second worm to rotate, which in turn drives the second worm wheel and the central shaft to rotate. The third bevel gear, the fourth bevel gear, the rotating shaft, the first bevel gear, and the second bevel gear drive the rotating shaft to rotate, which in turn drives the two arc-shaped heat sinks to rotate away from the sensor body. The second arc-shaped end moves in the arc-shaped groove, so that the two arc-shaped heat sinks avoid the sensor body, which facilitates the operation of the subsequent self-inspection process.

[0021] (3) In this invention, the liquid ammonia at the bottom of the flow cavity absorbs the heat generated by the sensor body. The liquid ammonia vaporizes and moves upward to the top of the flow cavity. During the vaporization process, it absorbs heat to dissipate heat from the sensor body. The gaseous ammonia at the top of the flow cavity liquefies into liquid when it encounters cold air from the outside. Under the action of gravity, it flows to the bottom of the flow cavity. This cycle repeats to achieve heat dissipation and cooling of the sensor body. Attached Figure Description

The cooling mechanism 4 includes: a rotating shaft 401, two rotating shafts 401 being rotatably disposed below the connecting platform 108; an arc-shaped heat sink 402, the arc-shaped heat sink 402 being mounted on the rotating shaft 401; a third gear 403, the third gear 403 being mounted on the rotating shaft 401, the two third gears 403 meshing with each other; a first bevel gear 404, the first bevel gear 404 being mounted on one of the rotating shafts 401; a rotating shaft 405, the rotating shaft 405 being rotatably disposed within the clearance groove 1031; and a second bevel gear 406, the second bevel gear 406 being mounted on the rotating shaft 405, the first bevel gear 404 and the second bevel gear 406 meshing with each other.

[0049] A central shaft 407 is rotatably mounted inside the housing 100. A third bevel gear 408 is mounted on one end of the central shaft 407, and a fourth bevel gear 409 is mounted on the rotating shaft 405. The third bevel gear 408 and the fourth bevel gear 409 mesh with each other. A second worm gear 410 is mounted on the other end of the central shaft 407.

[0050] The housing 303 is equipped with a second rotating rod 316 and a third rotating rod 317. A second worm gear 318 is mounted on the second rotating rod 316, and the second worm wheel 410 meshes with the second worm gear 318. A sixth gear 319 is mounted on the third rotating rod 317, and the sixth gear 319 is positioned corresponding to the second gear 315. The second rotating rod 316 and the third rotating rod 317 are connected by a second belt 322.

[0051] A screw 320 is rotatably mounted inside the housing 303. A moving plate 321 is threadedly connected to the screw 320. A second gear 315 is rotatably mounted on the moving plate 321. A protrusion 3141 is mounted on the drive rod 314. A groove 3151 is formed inside the second gear 315, and the protrusion 3141 slides within the groove 3151. An clearance hole 3211 is formed inside the moving plate 321. A slot is formed at one end of the screw 320 and the drive rod 314.

[0052] The arc-shaped heat sink 402 includes: a first arc-shaped end 4021; a second arc-shaped end 4022, the second arc-shaped end 4022 being mounted on the first arc-shaped end 4021; a flow cavity 4023 is formed in the first arc-shaped end 4021 and the second arc-shaped end 4022, a rough surface 4024 is provided in the flow cavity 4023, and a coolant is provided in the flow cavity 4023, preferably liquid ammonia.

[0053] The housing 100 has two arc-shaped grooves 1001 inside. The second arc-shaped end 4022 moves within the arc-shaped groove 1001. A moving cylinder 113 is installed on the housing 100. A through groove 1131 is provided inside the moving cylinder 113. A first magnet 114 is installed on the housing 100. A second magnet 115 is installed on the moving cylinder 113. The second arc-shaped end 4022 is inserted into the through groove 1131.

[0054] In this embodiment, in the initial state, the arc-shaped heat sink 402 is clamped on the outside of the sensor body 105 (at the detection station). The liquid ammonia at the bottom of the flow cavity 4023 absorbs the heat generated by the sensor body 105, and the liquid ammonia vaporizes and moves upward to the top of the flow cavity 4023.

[0055] During vaporization, heat is absorbed to dissipate heat from the sensor body 105; the gaseous ammonia at the top of the flow cavity 4023 liquefies into liquid when it encounters cold air from the outside, and flows to the bottom of the flow cavity 4023 under the action of gravity. This cycle repeats to achieve heat dissipation and cooling of the sensor body 105.

[0056] In this embodiment, the initial state is as follows: Figure 3 As shown, the second arc-shaped end 4022 is inserted into the through groove 1131, so that the top of the second arc-shaped end 4022 is in contact with the outside air (to facilitate cooling and heat dissipation). The moving cylinder 113 moves upward, and the first magnet 114 attracts the second magnet 115 to limit the moving cylinder 113. The second arc-shaped end 4022 leaves the through groove 1131.

[0057] An electric flathead cutter is inserted into the slot of the screw 320, driving the screw 320 to rotate. According to the principle of thread transmission, the moving plate 321 is driven to move, which in turn drives the second gear 315 to move and mesh with the sixth gear 319.

[0058] An electric flathead cutter is inserted into the slot of the drive rod 314, which drives the drive rod 314 to rotate, thereby driving the second gear 315 to rotate, which in turn drives the sixth gear 319 and the third rotating rod 317 to rotate. The second belt 322 drives the second rotating rod 316 and the second worm gear 318 to rotate, which in turn drives the second worm wheel 410 and the central shaft 407 to rotate. The third bevel gear 408, the fourth bevel gear 409, the rotating shaft 405, the first bevel gear 404, and the second bevel gear 406 drive the rotating shaft 401 to rotate, thereby driving the two arc-shaped heat sinks 402 to rotate away from the sensor body 105. The second arc-shaped end 4022 moves within the arc-shaped groove 1001, allowing the two arc-shaped heat sinks 402 to avoid the sensor body 105, facilitating subsequent self-inspection processes.

[0059] In this embodiment, an electric flathead cutter is inserted into the slot of the screw 320, driving the screw 320 to rotate. According to the principle of thread transmission, the second gear 315 is driven to move and mesh with the first gear 313.

[0060] An electric flat-blade inserts into the slot of the drive rod 314, driving the drive rod 314 to rotate, which in turn drives the second gear 315 to rotate, which in turn drives the first gear 313 and the fourth rotating rod 311 to rotate. The first belt 312 drives the first rotating rod 304 and the first worm gear 305 to rotate, which in turn drives the rotary table 103 to rotate through the first worm wheel 302. This causes another sensor body 105 to move to the detection station (the arc-shaped heat sink 402 avoids interference with the movement of the sensor body 105). Similarly, a third sensor body 105 can be driven to move to the detection station. The results of the detection by the three sensor bodies 105 are compared to see if they are within the error range. If they are within the error range, it is normal; otherwise, it is abnormal. The pressure sensor of this invention is easy to self-test to deal with malfunctions or inaccurate measurements.

[0061] Multiple conductive blocks 1081 are installed on the connecting platform 108. The conductive blocks 1081 are in contact with the terminal section 107. The wire harness 109, the conductive blocks 1081, and the terminal section 107 are connected. The number of terminals in the terminal section 107 is the same as the number of conductive blocks 1081. In this embodiment, the terminal section 107 has three terminals. The wire harness 109 is in contact with the power supply and the data acquisition device.

[0062] like Figure 13 and Figure 14 As shown, there are three fixing sleeves 104 and sensor bodies 105. In this embodiment, there are three through slots 1121, and the three through slots 1121 are not connected (isolated), as shown. Figure 14 As shown in the figure, the through groove 1121 at point a is connected to the fixed sleeve 104 at point b.

[0063] Example 3: This example provides a method for operating a pressure sensor, including the following steps:

[0064] Step 1, Inspection Process: The threaded port 102 (with sealing ring) is installed on the tank body, and the inside of the tank is connected to the sensor body 105 (located at the inspection station). The sensor body 105 detects the air pressure inside the tank, realizing the detection of the pressure sensor.

[0065] Step 2, Cooling process: In the initial state, the arc-shaped heat sink 402 is clamped on the outside of the sensor body 105 (at the detection station). The liquid ammonia at the bottom of the flow cavity 4023 absorbs the heat generated by the sensor body 105, and the liquid ammonia vaporizes and moves upward to the top of the flow cavity 4023.

[0066] During the vaporization process, heat is absorbed to dissipate heat from the sensor body 105; the gaseous ammonia at the top of the flow cavity 4023 liquefies into liquid when it encounters cold air from the outside, and flows to the bottom of the flow cavity 4023 under the action of gravity. This cycle repeats to achieve heat dissipation and cooling of the sensor body 105.

[0067] Step 3, Avoidance Process: Initial state as follows Figure 3 As shown, the second arc-shaped end 4022 is inserted into the through groove 1131, so that the top of the second arc-shaped end 4022 is in contact with the outside air (to facilitate cooling and heat dissipation). The moving cylinder 113 moves upward, and the first magnet 114 attracts the second magnet 115 to limit the moving cylinder 113. The second arc-shaped end 4022 leaves the through groove 1131.

[0068] An electric flathead cutter is inserted into the slot of the screw 320, driving the screw 320 to rotate. According to the principle of thread transmission, the moving plate 321 is driven to move, which in turn drives the second gear 315 to move and mesh with the sixth gear 319.

[0069] An electric flat blade is inserted into the slot of the drive rod 314, which drives the drive rod 314 to rotate, thereby driving the second gear 315 to rotate, which in turn drives the sixth gear 319 and the third rotating rod 317 to rotate. The second belt 322 drives the second rotating rod 316 and the second worm gear 318 to rotate, which in turn drives the second worm wheel 410 and the central shaft 407 to rotate. The third bevel gear 408, the fourth bevel gear 409, the rotating shaft 405, the first bevel gear 404, and the second bevel gear 406 drive the rotating shaft 401 to rotate, thereby driving the two arc-shaped heat sinks 402 to rotate away from the sensor body 105. The second arc-shaped end 4022 moves within the arc-shaped groove 1001, allowing the two arc-shaped heat sinks 402 to avoid the sensor body 105, which facilitates the operation of subsequent self-inspection processes.

[0070] Step 4, Self-inspection process: The electric flathead cutter is inserted into the slot of the screw 320, driving the screw 320 to rotate. According to the thread transmission principle, it drives the second gear 315 to move and mesh with the first gear 313. The electric flathead cutter is inserted into the slot of the drive rod 314, driving the drive rod 314 to rotate, which in turn drives the second gear 315 to rotate, driving the first gear 313 and the fourth rotating rod 311 to rotate. The first belt 312 drives the first rotating rod 304 and the first worm gear 305 to rotate, and the first worm wheel 302 drives the rotary table 103 to rotate, driving another sensor body 105 to move to the detection station (the arc-shaped heat sink 402 avoids interference with the movement of the sensor body 105). Similarly, the third sensor body 105 can be driven to move to the detection station. The results of the detection of the three sensor bodies 105 are compared to see if they are within the error range. If they are within the error range, it is normal; otherwise, it is abnormal. The pressure sensor of this invention is easy to self-inspect to deal with the situation of failure or inaccurate measurement.
