Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically, it relates to a wireless monitoring sensor. Background Technology

[0002] In highly developed modern industry, the development of modern testing technology toward digitalization and informatization has become an inevitable trend. The front end of the testing system is the sensor, and the vibration sensor is one of the key components in testing technology. Its main function is to receive the mechanical quantity generated by vibration and convert it into a proportional electrical quantity.

[0003] Chinese patent CN216746416U discloses a wireless vibration monitoring sensor. It employs a threaded connection to install a protective housing, facilitating quick and easy installation and removal of the housing and thus the installation of the vibration sensor. A sealing ring inside the threaded interface further enhances the seal between the housing and the mounting plate. A heat-conducting copper plate inside the housing transfers the heat generated by the vibration sensor to a heat sink, improving heat dissipation efficiency and preventing overheating within the housing, ensuring normal operation. However, the mounting method using bolts at the four corners of the mounting plate requires a suitable mounting surface and pre-drilled holes on the device surface. This can limit installation on irregularly shaped, uneven, or drillable devices, making it difficult to ensure a tight fit between the sensor and the device, thus affecting vibration detection accuracy.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wireless monitoring sensor that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A wireless monitoring sensor includes: a mounting plate, a protective shell, and a vibration sensor. A threaded retaining ring is connected to the top of the mounting plate, and the mounting plate is connected to the bottom of the protective shell through the threaded retaining ring. The vibration sensor is located inside the protective shell. A fan compartment is opened at the top of the interior of the protective shell, and a fan is connected inside the fan compartment. A ventilation hole is opened between the fan compartment and the interior of the protective shell. Threaded holes are opened at the four corners of the surface of the mounting plate, and magnetic blocks are embedded at the bottom of the threaded holes. An adhesive silicone layer is covered and connected to the bottom of the mounting plate.

[0008] Optionally, the mounting plate has a central through hole at the threaded fixing ring, and a baffle is connected to the bottom end of the central through hole, with the bottom end of the vibration sensor abutting against the surface of the baffle.

[0009] Optionally, a sealing ring is connected to the surface of the baffle, and the bottom end of the vibration sensor is in close contact with the sealing ring.

[0010] Optionally, a heat-conducting copper plate is connected to the inner wall of the protective shell, and the inner wall of the heat-conducting copper plate is tightly attached to the outer wall of the vibration sensor.

[0011] Optionally, thermally conductive silicone grease is applied between the thermally conductive copper plate and the vibration sensor.

[0012] Optionally, a heat dissipation fin is connected below the ventilation hole, and the other end of the heat dissipation fin is connected to a heat-conducting copper plate.

[0013] Optionally, multiple air guide grooves are provided between the protective shell and the heat-conducting copper plate, and the height of the air guide grooves is higher than that of the heat-conducting copper plate. A heat dissipation hole is provided at the bottom of the air guide groove, and the heat dissipation hole penetrates the surface of the protective shell.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up a mounting plate, the mounting plate integrates three mounting structures: threaded holes, magnetic blocks, and adhesive silicone layers. It can adapt to the equipment being tested with different materials and surfaces. For conventional equipment with threaded holes, bolts can be used for installation to ensure a stable connection. For ferromagnetic material surfaces, magnetic block adsorption installation does not require drilling, making the operation simple and quick. For non-ferromagnetic surfaces that are not suitable for drilling, the adhesive silicone layer provides a flexible solution, which greatly expands the application scenarios of the sensor. Whether it is industrial equipment, building structures, or home appliances, different types of monitoring objects can be easily installed, reducing the situation where it cannot be used due to installation limitations.

[0016] 2. By incorporating structures such as fans and heat sinks, the fans actively draw in cool air through ventilation holes, accelerating air convection and quickly removing heat from the heat sinks. Meanwhile, the thermally conductive copper plate and heat sinks utilize their excellent thermal conductivity and large surface area to rapidly transfer and dissipate the heat generated by the vibration sensor. Compared to single heat dissipation methods, this composite heat dissipation approach is more effective in dealing with the heat generated by the sensor under different operating conditions, ensuring that the sensor remains within a suitable operating temperature range.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-5 As shown, this embodiment provides a wireless monitoring sensor, including: a mounting plate 1, a protective shell 2, and a vibration sensor 8. The top of the mounting plate 1 is connected to a threaded retaining ring 5, and the mounting plate 1 is connected to the bottom of the protective shell 2 through the threaded retaining ring 5. The vibration sensor 8 is located inside the protective shell 2. A fan compartment 12 is opened at the top inside the protective shell 2, and a fan 13 is connected inside the fan compartment 12. A ventilation hole 14 is opened between the fan compartment 12 and the inside of the protective shell 2. Threaded holes 3 are opened at the four corners of the surface of the mounting plate 1, and a magnetic block 31 is embedded at the bottom of the threaded hole 3. An adhesive silicone layer 32 is covered and connected to the bottom of the mounting plate 1.

[0029] Mounting plate 1 is the basic support component of the entire sensor, responsible for connecting the protective shell 2 and fixing it to the surface of the monitored equipment. The main function of the protective shell 2 is to protect the internal vibration sensor 8 from interference and damage from external environmental factors (such as collisions, dust, moisture, etc.), ensuring that the vibration sensor 8 can work in a stable environment. The vibration sensor 8 is placed inside the protective shell 2, and its function is to accurately sense the vibration of the equipment and convert this vibration information into a processable signal for subsequent analysis and transmission. Mounting plate 1 is connected to the bottom of the protective shell 2 by a threaded retaining ring 5, which not only ensures the stability of the connection between the protective shell 2 and mounting plate 1, but also facilitates disassembly when needed, making it convenient for maintenance or replacement of the internal vibration sensor 8. The threaded holes 3 at the four corners of the surface of mounting plate 1 can be used for traditional bolt installation. When the surface of the monitored equipment has corresponding threaded holes, bolts can be used. The mounting plate 1 is fixed to the equipment through the threaded hole 3, while the setting of the magnetic block 31 provides more flexibility for installation. For equipment surfaces made of ferromagnetic materials, the sensor can be directly adsorbed onto the equipment by the magnetic force of the magnetic block 31 without drilling, simplifying the installation process. For some equipment with surfaces that are not suitable for drilling and whose materials are not ferromagnetic, the adhesive layer 32 can be used to stick the mounting plate 1 to the equipment surface to fix the sensor. This multifunctional installation structure enables the sensor to adapt to the monitored equipment with different materials and surface conditions, greatly improving its installation adaptability. The fan compartment 12 provides a relatively independent and stable installation space for the fan 13, ensuring the stability of the fan 13 during operation. The ventilation hole 14 creates an air circulation channel, allowing external cold air to be introduced into the protective shell 2 through the ventilation hole 14 to exchange heat with the heated vibration sensor 8 and other components.

[0030] In this embodiment, the mounting plate 1 has a central through hole at the threaded fixing ring 5, and a baffle 6 is connected to the bottom end of the central through hole. The bottom end of the vibration sensor 8 abuts against the surface of the baffle 6, and a sealing ring 7 is connected to the surface of the baffle 6. The bottom end of the vibration sensor 8 is in close contact with the sealing ring 7. The central through hole at the threaded fixing ring 5 of the mounting plate 1 provides precise positioning for the installation of the vibration sensor 8. The baffle 6 connected to the bottom end of the central through hole supports the vibration sensor 8, so that the bottom end of the vibration sensor 8 can stably abut against the surface of the baffle 6, ensuring that the position of the vibration sensor 8 on the mounting plate 1 is fixed, avoiding displacement due to vibration and other factors during operation, which would affect the accuracy of the monitoring data. The sealing ring 7 is in close contact with the bottom end of the vibration sensor 8, enhancing the protective performance. The sealing ring 7 can effectively block external dust, moisture and other impurities, preventing them from entering the sensor through the gap between the central through hole and the vibration sensor 8, avoiding sensor failure or damage due to impurities, and extending the service life of the sensor.

[0031] A thermally conductive copper plate 9 is connected to the inner wall of the protective shell 2. The inner wall of the thermally conductive copper plate 9 is tightly attached to the outer wall of the vibration sensor 8. Thermally conductive silicone grease is applied between the thermally conductive copper plate 9 and the vibration sensor 8. The thermally conductive copper plate 9 has good thermal conductivity and can quickly transfer the heat generated by the vibration sensor 8 during operation. The role of the thermally conductive silicone grease is to fill the tiny gap between the thermally conductive copper plate 9 and the vibration sensor 8, further improving the heat conduction efficiency and ensuring that heat can be efficiently transferred from the vibration sensor 8 to the thermally conductive copper plate 9, laying the foundation for the subsequent heat dissipation process.

[0032] A heat dissipation fin 11 is connected below the ventilation hole 14. The other end of the heat dissipation fin 11 is connected to the thermally conductive copper plate 9. When the thermally conductive copper plate 9 absorbs the heat from the vibration sensor 8, the heat is transferred to the heat dissipation fin 11. The heat dissipation fin 11 increases the contact area with the air by increasing the surface area, which is beneficial for dissipating heat into the surrounding air. When the air introduced by the ventilation hole 14 flows through the heat dissipation fin 11, it can accelerate the heat removal speed and enhance the heat dissipation effect. Multiple air guide slots 10 are opened between the protective shell 2 and the thermally conductive copper plate 9, and the height of the air guide slots 10 is higher than that of the thermally conductive copper plate 9. A heat dissipation hole 4 is provided at the bottom of the protective shell 2, which penetrates the surface of the protective shell 2. The air guide channel 10 can guide the air entering through the ventilation hole 14, so that it flows more orderly through the heat-conducting copper plate 9 and the heat dissipation fins 11, thereby improving the heat exchange efficiency between the air and the heat dissipation components. The heat dissipation hole 4 at the bottom of the air guide channel 10 penetrates the surface of the protective shell 2. After heat exchange, the hot air is discharged from the protective shell 2 through the heat dissipation hole 4, forming a complete air circulation path, which further enhances the heat dissipation capacity of the heat dissipation system and ensures that the vibration sensor 8 is always within a suitable operating temperature range, thereby ensuring the stable operation and monitoring accuracy of the sensor.

[0033] Working principle:

[0034] During installation, select the appropriate installation method according to the material and surface conditions of the equipment being tested. If there are screw holes on the surface of the equipment, the bolts can be screwed into the screw holes through the threaded holes 3 at the four corners of the mounting plate 1 to fix the mounting plate 1. If the equipment is made of ferromagnetic material, the sensor can be directly adsorbed onto the surface of the equipment through the magnetic block 31. For equipment that is not suitable for drilling and is not ferromagnetic, after cleaning the surface of the equipment, the adhesive silicone layer 32 at the bottom of the mounting plate 1 is pasted onto the surface of the equipment. Then, align the bottom end of the vibration sensor 8 with the center through hole of the mounting plate 1 so that it abuts against the surface of the baffle 6, ensuring that the sealing ring 7 is in close contact with the bottom end of the vibration sensor 8. Connect the protective shell 2 to the mounting plate 1 through the threaded fixing ring 5 and tighten it to ensure a firm connection.

[0035] Vibration detection: When the equipment vibrates during operation, vibration sensor 8 accurately senses the vibration and converts it into an electrical signal;

[0036] Heat dissipation process: The vibration sensor 8 generates heat during operation, which is transferred to the thermally conductive copper plate 9 through thermal grease, and then transferred to the heat dissipation fins 11 by the thermally conductive copper plate 9. At the same time, the fan 13 starts, and external cold air enters the protective shell 2 through the ventilation hole 14, flows through the heat dissipation fins 11 and carries away the heat. The hot air is discharged from the protective shell 2 through the air guide 10 and the heat dissipation hole 4, realizing the circulation heat dissipation.
