Description

Technical Field

[0001] The invention belongs to the technical field of sensors, and in particular relates to a wireless temperature and pressure sensor. Background Art

[0002] Wireless temperature and pressure sensors are commonly used in industrial practice and are widely used in various automation and detection systems, such as hydrological monitoring and control systems, petrochemicals, environmental protection, water pipe network monitoring, power station operation inspections, locomotive braking systems, thermal power units, light industry, mechanical metallurgy, building automation, constant pressure water supply systems, etc. This sensor transmits data wirelessly, and wireless monitoring can be achieved wherever there is a mobile phone signal;

[0003] However, the detection end of the wireless temperature and pressure sensor is composed of crimped and temperature sensing elements. Due to different installation environments, the wires of the wireless temperature and pressure sensor are often longer (this is why people choose longer wires instead of shorter ones when selecting wire harnesses). However, if the wire harness is too long, part of the wire harness will bend or drag on the ground. When it is placed for a long time, the risk of the wire harness will increase, which will indirectly affect the detection effect of the wireless temperature and pressure sensor.

[0004] In view of this, a wireless temperature and pressure sensor is proposed. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In view of the following technical problems in the prior art: the detection end of the wireless temperature and pressure sensor is composed of a crimped and temperature-sensitive element. Due to the different installation environments in different environments, the wires of the wireless temperature and pressure sensor are often longer (this is why people choose long rather than short when selecting a wiring harness). However, if the wiring harness is too long, part of the wiring harness will bend or drag on the ground. When it is placed for a long time, the risk of the wiring harness will increase, indirectly affecting the detection effect of the wireless temperature and pressure sensor.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a wireless temperature and pressure sensor, comprising an instrument, a wiring harness and a detection head; a connector is provided at the bottom end of the instrument, wherein the connector is used to stably connect the top end of the wiring harness to the instrument, a wireless transmission component is connected to the side of the top end of the instrument, the wireless transmission component is used for transmitting wireless signals, and the detection head is connected to the bottom end of the wiring harness; a mounting ring is installed on the outside of the bottom end of the instrument, a positioning plate is installed on the bottom surface of the mounting ring, a telescopic inner plate is connected to the bottom end of the positioning plate, a telescopic outer plate is provided on the outside of the telescopic inner plate, a load-bearing shaft is connected to the inner edge of the telescopic outer plate, and a collecting tube is provided on the outside of the load-bearing shaft.

[0008] As an optimal technical solution for the wireless temperature and pressure sensor, a telescopic groove is provided at the top of the telescopic outer plate, the telescopic inner plate slides in the telescopic groove, a threaded hole is provided on the side of the top of the telescopic outer plate, the threaded hole is communicated with the telescopic groove, a bolt is threadedly transmitted in the threaded hole, and when the bolt is tightened, the output end of the bolt will be in contact with and squeezed against the surface of the telescopic inner plate due to the characteristics of the thread, so that the telescopic inner plate is limited to a specified position in the telescopic groove.

[0009] As a preferred technical solution of the wireless temperature and pressure sensor, a rotation hole is opened at the center of the bottom end of the telescopic outer plate, and a rotation shaft is rotatably connected to the rotation hole.

[0010] As an optimal technical solution for the wireless temperature and pressure sensor, an operating cavity is provided inside the bearing shaft, the operating cavity is communicated with the rotating hole, the rotating shaft passes through the operating cavity, a guide channel is provided on the surface of the bearing shaft, and an insert is provided in the guide channel for telescopic movement.

[0011] As an optimal technical solution for the wireless temperature and pressure sensor, both ends of the collecting tube are connected with winding reels, wherein the winding reels are used to prevent the wiring harness from slipping during storage, a through hole one is provided at the center of the winding reel, a through hole two is provided at the center of the collecting tube, a circumferentially distributed card slots are provided at the inner edge of the through hole two, and the plug block is plugged into the card slot. When the plug block is plugged into the card slot, the collecting tube cannot rotate.

[0012] As an optimal technical solution for the wireless temperature and pressure sensor, an articulated rod is hinged between the plug block and the rotating shaft, and both ends of the articulated rod are rotatably connected to the plug block and the rotating shaft through a rotating shaft.

When rotated to the maximum range, the plug block retracts into the guide channel, and the collecting barrel can rotate normally at this time. When the rotation of the rotating shaft is cancelled, the linkage plate will reset so that the plug block is inserted into the corresponding slot.

[0014] As a preferred technical solution of the wireless temperature and pressure sensor, a mounting plate is provided on the outer side of the winding reel, wherein the mounting plate is used to mount the winding reel at a designated position.

[0015] The beneficial effects of the present invention are as follows: by rotating the rotating shaft, under the action of the articulated rod, the plug block can telescopically move in the guide channel, at which time the tip of the plug block disengages from the slot, and the collecting cylinder can rotate relative to the load-bearing shaft. When the collecting cylinder rotates, both ends of the wire harness are unwound, and the telescopic outer plate is pulled at this time, so that the exposed wire harness is in a taut state. When the appropriate position is adjusted, the rotating shaft is released, and under the action of the torsion piece, the rotating shaft, the articulated rod and the plug block are reset. At this time, the collecting cylinder cannot be rotated, and the bolt is locked. At this time, the reeled state of the wire harness is limited, so as to ensure that the wire harness does not drag on the ground as a whole under different length applications.

At this time, the collecting cylinder 303 can rotate relative to the load-bearing shaft 209. At this time, when the collecting cylinder 303 rotates, the two ends of the wire harness 102 are unwound, and the telescopic outer plate 203 is pulled at this time, so that the exposed wire harness 102 is in a taut state. When the appropriate position is adjusted, the rotating shaft 208 is loosened. Under the action of the torque member 215, the rotating shaft 208, the hinge rod 212 and the plug block 211 are reset. At this time, the collecting cylinder 303 cannot be rotated, and the bolt 206 is locked.
