Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and in particular to an intelligent wireless temperature sensor. Background Technology

[0002] In industrial production and equipment monitoring, wireless temperature sensors are widely used to monitor equipment temperature in real time to ensure operational safety and prevent malfunctions. However, existing wireless temperature sensors are typically fixed in place, and their sensing end positions cannot be flexibly adjusted, making it difficult to adapt to temperature measurement needs at different distances or in complex environments in practical applications. Furthermore, the mechanical structure of traditional sensors lacks stability, and positional shifts or loosening are prone to occur during adjustment or reset, affecting temperature measurement accuracy.

[0003] Therefore, there is an urgent need for an intelligent wireless temperature sensor that can flexibly adjust the temperature measurement distance, has high stability and anti-interference capabilities, in order to meet the diverse needs of modern industry. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of existing technologies and provide an intelligent wireless temperature sensor. It solves problems such as fixed temperature measurement distance, insufficient stability, and poor anti-interference capabilities in existing technologies, and has broad application prospects and practical value.

[0005] The technical solution adopted by this utility model to achieve its technical objective is: an intelligent wireless temperature sensor, including a sensor body and a housing, one end of which is slidably connected inside the housing; the sensor body is embedded inside the housing through a sliding connection, which enables it to be retractable and adjustable, and is convenient to adapt to different temperature measurement distance requirements.

[0006] A traction rope is fixedly installed at one end of the sensor body. After the traction rope changes direction by the guide wheel, it is wound around the winding roller. Both the guide wheel and the winding roller are rotatably installed inside the housing.

[0007] The traction rope is fixed to one end of the sensor body, and after the guide wheel changes its direction, it is wound around the winding roller. Both the guide wheel and the winding roller are rotatably set inside the housing. The guide wheel is used to change the direction of the traction rope, and the winding roller controls the extension and retraction of the sensor body by rotating to tighten or release the traction rope.

[0008] One end of the winding roller is equipped with a one-way rotation limiting mechanism. This mechanism allows the winding roller to rotate in one direction to wind the traction rope. The traction rope pulls one end of the sensor body inside the housing, adjusting the position of the other end of the sensor body. The one-way rotation limiting mechanism, located at one end of the winding roller, restricts the roller to rotate only in one direction to tighten the traction rope, ensuring the sensor body remains stable and preventing it from retracting.

[0009] Preferably, a filler block is provided between the sensor body and the housing. The filler block is fixed inside one vertical end of the housing and has a sliding groove. One end of the sensor body is slidably connected to the sliding groove. The filler block is fixed inside the housing to provide structural support; the sliding groove serves as a sliding track for the sensor body, ensuring its linear movement and preventing skewing.

[0010] Preferably, the slide groove is a rectangular groove with strip-shaped connecting grooves on both sides. Limiting strips are fixed to both sides of one end of the sensor body, and the limiting strips are slidably engaged in the connecting grooves. The limiting strips and the connecting groove limiting strips engage in the connecting grooves to form a sliding pair, restricting the rotational freedom of the sensor body and ensuring that it can only move along the direction of the slide groove.

[0011] Preferably, a spring is provided inside the chute, with one end of the spring abutting against the top of the sensor body and the other end abutting against the inner wall of the chute, for resetting the sensor body. The spring provides the resetting force; when the winding roller releases the traction rope, the spring pushes the sensor body back to its initial position, achieving automatic reset.

[0012] Preferably, both ends of the winding roller are rotatably disposed inside the housing, and a turntable is integrally connected to the top of one end of the roller. The turntable is rotatably connected inside the outer shell of the housing, and a cross groove is formed inside the turntable.

[0013] The turntable and the winding roller are integrated. The cross groove of the turntable can be driven by a screwdriver to manually adjust the rotation of the winding roller, thereby controlling the release and retraction of the traction rope.

[0014] Preferably, the unidirectional rotation limiting mechanism includes a winch and a wrench, the wrench being rotatably disposed inside the housing and reset by a torsion spring, and the winch limiting the unidirectional rotation of the winding roller.

[0015] The winch and winding roller are designed to allow the winding roller to rotate in one direction to tighten, preventing loosening in the opposite direction; the wrench is reset by a torsion spring and normally holds the winch; when manually turned, the restriction can be released, allowing the winding roller to rotate freely.

[0016] Preferably, one end of the wrench extends to the outside of the housing and is threadedly connected to a fixing nut. When the fixing nut is tightened, the wrench rotation is restricted. When loosened, the wrench can be manually operated to disengage from the winch wheel, allowing the winding roller to rotate freely. When the fixing nut is tightened, the wrench position is fixed, maintaining the unidirectional restriction function; when loosened, the wrench can be manually operated to release the winch wheel restriction, facilitating quick reset of the sensor body.

[0017] Preferably, the sensor body 1 uses an STM32 series microcontroller as the main control chip, integrates a high-precision digital temperature sensor, and supports multi-point temperature measurement. The outer shell of the sensor body 1 has been optimized for electromagnetic compatibility (EMC) and has built-in signal shielding to adapt to complex industrial environments.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This intelligent wireless temperature sensor, through the cooperation of a traction rope, a winding roller, and a one-way rotation limiting mechanism, achieves precise adjustment of the sensor body position, adapts to temperature measurement needs at different distances, and is easy to operate and highly stable.

[0019] This intelligent wireless temperature sensor features a spring inside a slide that automatically pushes the sensor body back to its original position after the restriction is lifted, improving the convenience and efficiency of the device.

[0020] This intelligent wireless temperature sensor features high stability. The design of the filler block, limit bar, and slide groove ensures the linear movement of the sensor body, preventing skew and enhancing the stability and durability of the structure.

[0021] This intelligent wireless temperature sensor has strong anti-interference capabilities. The sensor body adopts an STM32 series microcontroller and a high-precision digital temperature sensor, combined with electromagnetic compatibility (EMC) optimization and shell shielding technology, which effectively improves the anti-interference capability and signal transmission reliability in complex industrial environments.

[0022] This intelligent wireless temperature sensor supports multi-point temperature measurement, significantly reducing deployment costs and improving monitoring efficiency, and is suitable for various industrial scenarios. Attached Figure Description

[0030] Please see Figures 1-2 A smart wireless temperature sensor includes a sensor body 1 and a bent housing 2. One end of the sensor body 1 is slidably connected to the inside of the vertical end of the housing 2. The sensor body 1 uses an STM32 series microcontroller as the main control chip, integrating a high-precision digital temperature sensor and supporting multi-point temperature measurement. The housing of the sensor body 1 has been optimized for electromagnetic compatibility (EMC) and has built-in signal shielding to adapt to complex industrial environments.

[0031] A traction rope 5 is fixedly installed at one end of the sensor body 1. After the traction rope 5 changes direction by the guide wheel 6, it is wound around the winding roller 7. The guide wheel 6 and the winding roller 7 are arranged parallel to each other. After the traction rope 5 is turned by the guide wheel 6, it is wound vertically around the winding roller 7. The guide wheel 6 and the winding roller 7 are both rotatably arranged inside the transverse end of the housing 2.

[0032] One end of the winding roller 7 is provided with a one-way rotation limiting mechanism. The one-way rotation limiting mechanism enables the winding roller 7 to rotate in one direction to wind the traction rope 5. The traction rope 5 pulls one end of the sensor body 1 to move inside the housing 2, adjusting the position of the other end of the sensor body 1 so that the other end of the sensor body 1 can move away from the test object, thereby facilitating the adjustment of the distance between the other end of the sensor body 1 and the test object.

[0033] Furthermore, in this embodiment, a filling block 3 is provided between one end of the sensor body 1 and the interior of the vertical end of the housing 2. The filling block 3 is fixedly disposed inside the vertical end of the housing 2. After passing through the housing 2, one end of the sensor body 1 is slidably connected in a groove 301 opened inside the filling block 3. The groove 301 allows one end of the sensor body 1 to be slidably connected inside the vertical end of the housing 2.

[0034] The slide groove 301 is a rectangular groove with connecting grooves 302 on both sides. The connecting grooves 302 are strip-shaped structures. Limiting strips 101 are fixedly connected to both sides of the outer wall of one end of the sensor body 1. The limiting strips 101 are slidably connected inside the connecting grooves 302 and are confined within the connecting grooves 302. Through the setting of the limiting strips 101 and the connecting grooves 302, one end of the sensor body 1 can move stably inside the filling block 3.

[0035] Furthermore, in this embodiment, a spring 4 is provided inside the slide groove 301. One end of the spring 4 rests against the top of one end of the sensor body 1, and the other end rests against the inner wall of one end of the slide groove 301. By providing the spring 4, when the winding roller 7 is freed from the restriction of the unidirectional rotation limiting mechanism, the spring 4 can bring the other end of the sensor body 1 closer to the object being tested, thereby facilitating the adjustment of the distance between the other end of the sensor body 1 and the object being tested.

[0036] Furthermore, in this embodiment, both ends of the winding roller 7 are rotatably disposed inside the housing 2, and a turntable 10 is integrally connected to the top of one end. The turntable 10 is rotatably connected inside the outer shell of the housing 2, and a cross groove is formed inside the turntable 10. A screwdriver can be inserted into the cross groove of the turntable 10, and rotating the screwdriver can cause the turntable 10 and the winding roller 7 to rotate in one direction. The unidirectional rotation of the winding roller 7 winds the traction rope 5, and the traction rope 5 pulls one end of the sensor body 1 to move inside the housing 2 against the rebound force of the spring 4, so that the other end of the sensor body 1 can move away from the object being tested.

[0037] Furthermore, in this embodiment, the one-way rotation limiting mechanism includes a winch 8 and a wrench 9. One end of the wrench 9 is rotatably disposed inside the transverse end of the housing 2, and a torsion spring is also disposed inside the other end. Through the cooperative arrangement of the winch 8 and the wrench 9, the winch 8 can rotate in one direction, and by rotating the wrench in the opposite direction, the winch 8 can be released from the constraint of the wrench 9. The one-way rotation limiting mechanism here adopts the principle of a conventional one-way rotation limiting mechanism, which will not be described in detail here.

[0038] It is important to note that both ends of the wrench 9 are extended to maintain a rotatable connection with the housing 2; one end of the wrench 9 extends to the outside of the housing 2 and is threaded with a fixing nut 11, which locks the wrench 9 in place and keeps it in one position.

[0039] When the auger 8 is in normal use, the fixing nut 11 is locked in place. By inserting a screwdriver into the cross groove of the turntable 10, the winding roller 7 and the auger 8 can rotate in one direction. The winding roller 7 winds the traction rope 5 so that the other end of the sensor body 1 can move away from the object being tested.

[0040] When it is necessary to retract the wheel 8, loosen the fixing nut 11 and turn the wrench 9 in the opposite direction to disengage it from the wheel 8. Thus, the wheel 8 is unrestricted and the spring 4 pushes the other end of the sensor body 1 close to the object being tested.

[0041] The working principle and specific usage process of the intelligent wireless temperature sensor: The user drives the winding roller 7 to rotate in one direction by inserting a screwdriver into the cross groove of the turntable 10. The traction rope 5 is tightened after being turned by the guide wheel 6, pulling the sensor body 1 to slide outward along the slide groove 301 of the filling block 3. At the same time, the spring 4 is compressed. At this time, the winch wheel 8 and the locking wrench 9 ensure that the winding roller 7 does not retract. When resetting is required, loosen the fixing nut 11 and pull the wrench 9 to disengage from the winch 8. The spring 4 pushes the sensor body 1 back, and the traction rope 5 rotates freely with the winding roller 7, completing the position adjustment. The entire process achieves precise control of the temperature measuring end distance through mechanical linkage.

[0042] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural, procedural, or functional transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
