Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically relating to a glue-bonded vibration temperature sensor with loosening detection. Background Technology

[0002] In industrial production processes, the operating status of numerous devices is closely related to vibration and temperature. Traditional sensors typically only have a single vibration or temperature monitoring function. In complex industrial environments, single-function sensors cannot comprehensively reflect the operating status of equipment, hindering the timely detection of potential faults. Furthermore, due to uneven surfaces or lack of pre-designed installation locations on the monitored industrial equipment, traditional magnetic or bolt connections may be unsuitable. Adhesive-bonded connections may experience sensor detachment during installation and use due to various reasons, and most existing sensors lack detachment detection functionality. Once detached, the monitoring data will lose accuracy and may even mislead equipment maintenance personnel, leading to serious consequences.

[0003] Due to the aforementioned problems and defects, it is necessary to design a glue-bonded vibration temperature sensor with a loosening detection structure to achieve stable monitoring of the operating status of industrial equipment. Summary of the Invention

[0004] This invention is proposed to solve the problems existing in the prior art, and its purpose is to provide a glue-bonded vibration temperature sensor with loosening detection.

[0005] The technical solution of this utility model is: a glue-bonding vibration temperature sensor with loosening detection, including a sensor body and a glue-bonding fixing chamber for installation and fixation. A transverse mounting ring is formed on the inner wall of the glue-bonding fixing chamber, which divides the glue-bonding fixing chamber into an upper assembly connection cavity and a lower glue-bonding cavity. A loosening signal transmission coil is provided in the transverse mounting ring, and a loosening detection mechanism is provided in the inner wall of the glue-bonding fixing chamber. The loosening detection mechanism contacts or separates from the loosening signal transmission coil, thereby realizing glue loosening detection.

[0006] Furthermore, there are multiple loosening detection mechanisms, which are evenly distributed along the circumference of the adhesive fixing chamber.

[0007] Furthermore, the loosening detection mechanism includes a loosening detection mechanism spring, which is disposed in the countersunk hole of the adhesive fixing chamber. The free end of the loosening detection mechanism spring is in contact with the loosening detection mechanism metal contact piece, and the other end of the loosening detection mechanism metal contact piece is in contact with the loosening detection mechanism contact rod.

[0008] Furthermore, a transverse channel is formed in the transverse mounting ring, which accommodates the metal contact piece of the loosening detection mechanism, and the two are in a clearance fit.

[0009] Furthermore, when the adhesive fixing compartment is installed in the assembly position, the metal contact plate of the loosening detection mechanism is pushed up by the contact rod of the loosening detection mechanism, and the metal contact plate of the loosening detection mechanism comes into contact with the loosening signal transmission coil.

[0010] Furthermore, the release signal transmission coil includes a release signal transmission inner coil and a release signal transmission outer coil, each forming a ring, and the two are coaxial and non-contact.

[0011] Furthermore, an inner ring contact is provided on the outer wall of the inner ring of the release signal transmission, the inner ring contact spans across the outer ring of the release signal transmission, and an outer ring contact is provided on the outer wall of the outer ring of the release signal transmission.

[0012] Furthermore, a release signal arc segment is provided on the outer side of the release signal transmission outer ring, which is coaxial with it and assembled into a continuous arc shape, and release signal transmission contacts are provided at both ends of the release signal arc segment.

[0013] Furthermore, the loosening signal transmission contact corresponds to the inner ring contact / outer ring contact interval and is connected through the metal contact piece of the loosening detection mechanism below.

[0014] Furthermore, the inner ring and outer ring of the release signal transmission are in contact with the two contact ends of the release signal transmission head, respectively.

[0015] The beneficial effects of this utility model are as follows: This utility model integrates vibration monitoring, temperature monitoring, and loosening detection functions into one unit, simplifying the construction of the monitoring system and reducing system complexity and cost.

[0016] The internal thread structure design of the adhesive binding fixing compartment of this utility model is convenient for installation and can adapt to the adhesive binding needs of different curved surfaces.

[0017] This utility model's loosening detection mechanism can monitor the connection status between the sensor and the device under test in real time. Once loosening occurs, it immediately issues an audible and visual alarm, improving monitoring reliability and avoiding data distortion. Furthermore, the local audible and visual alarm function facilitates maintenance personnel in quickly locating the alarm device, improving inspection efficiency. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 12 As shown, a glue-bonding vibration temperature sensor with loosening detection includes a sensor body 1 and a glue-bonding fixing chamber 2 for mounting and fixing. A transverse mounting ring is formed on the inner wall of the glue-bonding fixing chamber 2, which divides the glue-bonding fixing chamber 2 into an upper assembly connection cavity and a lower glue-bonding cavity. A loosening signal transmission coil 14 is provided in the transverse mounting ring, and a loosening detection mechanism 8 is provided in the inner wall of the glue-bonding fixing chamber 2. The loosening detection mechanism 8 contacts or separates from the loosening signal transmission coil 14, thereby realizing glue loosening detection.

[0020] There are multiple loosening detection mechanisms 8, which are evenly distributed around the adhesive fixing chamber 2.

[0021] The loosening detection mechanism 8 includes a loosening detection mechanism spring 8-1, which is disposed in the countersunk hole of the adhesive fixing chamber 2. The free end of the loosening detection mechanism spring 8-1 is in contact with the loosening detection mechanism metal contact piece 8-2, and the other end of the loosening detection mechanism metal contact piece 8-2 is in contact with the loosening detection mechanism contact rod 8-3.

[0022] A transverse channel is formed in the transverse mounting ring, which accommodates the metal contact 8-2 of the loosening detection mechanism, and the two are in a clearance fit.

[0023] When the adhesive fixing compartment 2 is installed in the assembly position, the loosening detection mechanism contact rod 8-3 pushes against the loosening detection mechanism metal contact piece 8-2, and the metal contact piece 8-2 of the loosening detection mechanism comes into contact with the loosening signal transmission coil 14.

[0024] The release signal transmission coil 14 includes a release signal transmission inner coil 14-1 and a release signal transmission outer coil 14-2. The release signal transmission inner coil 14-1 and the release signal transmission outer coil 14-2 each form a ring, and the two are coaxial and non-contact.

[0025] An inner ring contact 14-8 is provided on the outer wall of the inner ring 14-1 of the release signal transmission, the inner ring contact 14-8 spans across the outer ring 14-2 of the release signal transmission, and an outer ring contact 14-7 is provided on the outer wall of the outer ring 14-2 of the release signal transmission.

[0026] The outer side of the release signal transmission outer ring 14-2 is provided with a release signal arc segment 14-9 that is coaxial with it and assembled into a continuous arc shape. Both ends of the release signal arc segment 14-9 are provided with release signal transmission contacts 14-3.

[0027] The loosening signal transmission contact 14-3 corresponds to the inner ring contact 14-8 and the outer ring contact 14-7 at intervals, and is connected through the metal contact piece 8-2 of the loosening detection mechanism below.

[0028] The inner ring 14-1 and the outer ring 14-2 of the loosening signal transmission are in contact with the two contact ends of the loosening signal transmission head 12, respectively.

[0029] Specifically, there are four loosening detection mechanisms 8, and three loosening signal arc segments 14-9.

[0030] Specifically, the release signal transmission contact 14-3 between adjacent release signal arc segments 14-9 is aligned with the metal contact 8-2 of the two release detection mechanisms 8; the third release signal transmission contact 14-3 and the outer ring contact 14-7 are aligned with the metal contact 8-2 of the third release detection mechanism; and the fourth release signal transmission contact 14-3 and the inner ring contact 14-8 are aligned with the metal contact 8-2 of the fourth release detection mechanism.

[0031] like Figure 12 As shown, the release signal transmission coil circuit 14-6 includes four release detection mechanism metal contact opening / closing positions 14-5 and one release signal transmission line connection position 14-4. The release detection mechanism metal contact opening / closing positions 14-5 correspond to the release detection mechanism metal contact 8-2. In the released state, the release detection mechanism contact rod 8-3 extends outward, and the release detection mechanism metal contact 8-2 moves downward, thereby separating from the corresponding contact point, so that the release detection mechanism metal contact opening / closing position 14-5 is in the open position, and the release signal transmission coil circuit 14-6 is disconnected. The release signal transmission line connection position 14-4 is connected to the release signal transmission head 12, and the release signal transmission head 12 is connected to the signal flexible wire 18.

[0032] Specifically, an internal thread is formed in the assembly connection cavity of the adhesive fixing compartment 2, and an external thread is formed in the lower section of the sensor body 1. The two are connected by the thread.

[0033] Correspondingly, the adhesive fixing chamber 2 is connected to the sensor body 1 by a screwing action, and the relative height between the adhesive fixing chamber 2 and the vibration sensor synapse 15 is changed by adjusting the screwing angle.

[0034] This configuration allows the sensor to adapt to the adhesive application requirements of different surface curvatures of the device being tested.

[0035] Specifically, the sensor body 1 incorporates a piezoelectric ceramic vibration sensor 3, which features high sensitivity and rapid response, converting the physical signals generated by the vibration of the industrial equipment being tested into electrical signals. The piezoelectric ceramic vibration sensor 3 is in direct contact with the industrial equipment being tested via vibration sensor synapses 15.

[0036] This setting can improve the sensitivity and accuracy of vibration detection.

[0037] Specifically, a glue injection groove 16 and a glue injection venting groove 17 are provided at the threaded part below the sensor body 1, and the glue injection groove 16 and the glue injection venting groove 17 are used to inject glue into the glue fixing chamber 2.

[0038] This design facilitates the installation process and effectively removes air bubbles generated during the application, ensuring the tightness of the adhesive.

[0039] Specifically, the sensor body 1 is made of a high-temperature resistant and corrosion-resistant material.

[0040] This setup effectively improves the sensor's applicability in complex environments.

[0041] Specifically, the sensor body 1 has an infrared temperature sensor 4 built in it. The infrared temperature sensor 4 uses a non-contact measurement method to detect the surface temperature of the industrial equipment being tested and converts the temperature signal into an electrical signal.

[0042] This setup improves adaptability to the surface shape of the industrial equipment being inspected.

[0043] Specifically, the sensor body 1 has a built-in microcontroller circuit board 5, which is equipped with a power signal line 6, an alarm indicator light 7, a power button 10, a buzzer alarm 9, and a microcontroller module 11.

[0044] This design effectively improves the integration of this invention, reduces its size, and helps maintenance personnel quickly locate faulty equipment through audible and visual alarms.

[0045] Specifically, the microcontroller circuit board 5 is connected to the piezoelectric ceramic vibration sensor 3, the infrared temperature sensor 4, and the release signal transmission head 12 via the signal cable 18. The release signal transmission head 12 has a built-in spring, which presses the release signal transmission coil 14.

[0046] This configuration allows the vibration, temperature, and loosening electrical signals generated by the piezoelectric ceramic vibration sensor, infrared temperature sensor, and loosening detection mechanism to be transmitted to the microcontroller circuit board.

[0047] Specifically, an alarm light strip 13 is also installed on the sensor body 1.

[0048] This configuration allows the warning light emitted by the alarm indicator to be directed out of the sensor body 1, making it convenient for maintenance personnel to observe from various angles.

[0049] Specifically, when the adhesive fixing chamber 2 is tightly attached to the surface of the industrial equipment being tested, the metal contact piece 8-2 of the loosening detection mechanism is lifted by the contact rod 8-3 of the loosening detection mechanism, thereby closing the loosening signal transmission circuit 14-6, and transmitting the loosening signal to the loosening signal transmission head 12 through the inner loosening signal transmission ring 14-1 and the outer loosening signal transmission ring 14-2.

[0050] Specifically, when the adhesive fixing chamber 2 becomes loose from the surface of the industrial equipment being tested, the contact rod 8-3 of the loosening detection mechanism extends outward, and the spring 8-1 of the loosening detection mechanism presses down on the metal contact piece 8-2 of the loosening detection mechanism. At this time, the metal contact piece 8-2 of the loosening detection mechanism is not in contact with the corresponding contact point, and the loosening signal transmission coil circuit 14-6 is disconnected, and a loosening alarm feedback is generated.

[0051] The working process of this utility model is as follows: Before installation, the installer confirms that the surface of the equipment to be tested is clean and dry. The adhesive fixing chamber 2 is screwed to the sensor body 1. After connection, the vibration temperature sensor 3 is placed on the surface of the equipment to be monitored. By further screwing the adhesive fixing chamber 2, the vibration sensor synapse 15 is brought into contact with the surface of the equipment to be tested. At the same time, the installer observes and confirms that the loosening detection mechanism 8 has returned to its original position. The sensor fixing adhesive is slowly injected through the glue injection tank 16. After the fixing adhesive has solidified, the power button 10 is turned on to start the operation.

[0052] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
