Description

Technical Field

[0001] This utility model belongs to the field of vibration sensor technology, specifically relating to an explosion-proof integrated vibration sensor. Background Technology

[0002] An explosion-proof integrated vibration sensor is a vibration monitoring device specifically designed for hazardous explosive environments. It integrates vibration monitoring functions with an explosion-proof design, enabling reliable monitoring of equipment vibration status in flammable and explosive environments. This provides crucial data for equipment fault diagnosis and maintenance. The explosion-proof integrated vibration sensor can monitor equipment vibration acceleration, velocity, displacement, and other parameters in real time, covering vibration signals in different frequency bands, including high-frequency (such as bearing failure) and low-frequency (such as structural vibration).

[0003] During installation, explosion-proof integrated vibration sensors typically connect to the bottom of the sensor via a threaded rod, with the other end fitting into a threaded hole in the equipment housing. This installation method significantly improves on-site installation convenience due to the quick-connect capability of the threaded structure. However, the threaded connection between the sensor and the rod is not a sealed structure. During long-term operation, liquid media such as water and oil from the environment can gradually seep into the sensor through the thread gaps. This intrusion may cause internal circuitry to become damp, components to corrode, and even affect the integrity of the explosion-proof structure, thus posing a potential threat to the sensor's safe operation and monitoring reliability. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof integrated vibration sensor, addressing the problem that the connection between the sensor and the threaded rod is not a sealed structure. During long-term operation, liquid media such as water and oil from the environment can easily seep into the sensor through the thread gaps. This intrusion can lead to moisture damage to internal circuitry, corrosion of components, and even affect the integrity of the explosion-proof structure, thus posing a potential threat to the sensor's safe operation and monitoring reliability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof integrated vibration sensor, comprising a vibration sensor, one end of which is equipped with a connector, and the other end of which is screwed with a connecting screw, and a pressure plate is threaded onto the outer wall of the connecting screw;

[0006] A sealing ring is connected to one side of the pressure plate. An opening is provided on the outer wall of the vibration sensor connected to the connecting screw. A sealing groove is provided on the inner wall of the opening, and the pressure plate is installed in the opening.

[0007] In order to form a sealed structure between the vibration sensor and the connecting screw end, as an explosion-proof integrated vibration sensor of this utility model, preferably, a mounting groove is formed on the outer wall of one side of the pressure plate, and a sealing ring is installed inside the mounting groove;

[0008] The sealing ring is installed in the sealing groove on the side away from the mounting groove, and the sealing ring and the sealing groove form a sealing connection structure.

[0009] In order to form an effective sealing structure between the sealing ring and the connecting screw end, as an explosion-proof integrated vibration sensor of this utility model, preferably, a sealing sleeve is glued to the bottom of the pressure plate, and the sealing sleeve is movably fitted onto the outer wall of the connecting screw.

[0010] An annular groove is formed on the outer wall of the sealing sleeve, and a tightening ring is interference-fitted inside the annular groove. The sealing sleeve and the screw connection end form a sealing structure through the tightening ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, first connect the connecting screw to the bottom mating end of the vibration sensor. Then, adjust the pressure plate along the threaded path on the connecting screw towards the bottom of the vibration sensor, ultimately causing the pressure plate to firmly press the sealing ring into the sealing groove. At this point, the connecting screw and the connection end of the vibration sensor form a sealing layer through this structure, preventing water or oil stains from penetrating into the vibration sensor through the threaded structure on the connecting screw and the vibration sensor, thus ensuring the safety of the vibration sensor during use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides the following technical solution: an explosion-proof integrated vibration sensor, including a vibration sensor 1, a connector 2 installed at one end of the vibration sensor 1, a connecting screw 3 screwed to the other end of the vibration sensor 1, and a pressure plate 4 threaded onto the outer wall of the connecting screw 3;

[0022] When in use, a threaded hole that matches the connecting screw 3 is pre-drilled on the housing of the device to be tested. Then, one end of the connecting screw 3 is screwed onto the bottom of the vibration sensor 1, and the other end of the connecting screw 3 is connected to the threaded hole on the housing of the device.

[0023] Next, connect vibration sensor 1 to the transmission line via connector 2. When in use, vibration sensor 1 can monitor the vibration frequency of the equipment in real time and transmit it to the terminal for display.

[0024] Vibration sensor 1 is an explosion-proof integrated vibration sensor, model number: CZ9300 sensor.

[0025] A sealing ring 5 is connected to one side of the pressure plate 4. An opening 6 is provided on the outer wall where the vibration sensor 1 is connected to the connecting screw 3. A sealing groove 7 is provided on the inner wall of the opening 6. The pressure plate 4 is installed in the opening 6.

[0026] Preferably, a mounting groove 41 is formed on the outer wall of one side of the pressure plate 4, and a sealing ring 5 is installed inside the mounting groove 41;

[0027] The sealing ring 5 is installed in the sealing groove 7 on the side away from the mounting groove 41, and the sealing ring 5 and the sealing groove 7 form a sealing connection structure.

[0028] In practical use, after the connecting screw 3 is connected to the vibration sensor 1, the pressure plate 4 is adjusted upwards. When the pressure plate 4 moves upwards, it will drive the vibration sensor 1.

[0029] Preferably, a sealing sleeve 31 is bonded to the bottom of the pressure plate 4. The sealing sleeve 31 is movably fitted onto the outer wall of the connecting screw 3, and the sealing ring 5 moves towards the sealing groove 7. Finally, the pressure plate 4 will mate with the opening 6 and press the sealing ring 5 into the sealing groove 7, thereby forming a sealing structure at the connection end of the connecting screw 3 and the vibration sensor 1 that effectively isolates external water or oil stains from intrusion.

[0030] An annular groove 32 is formed on the outer wall of the sealing sleeve 31. A tightening ring 33 is interference-fitted inside the annular groove 32. The sealing sleeve 31 and the connecting screw 3 are connected to form a sealing structure through the tightening ring 33.

[0031] In practical use, first connect the connecting screw 3 to the bottom mating end of the vibration sensor 1. Then, adjust the pressure plate 4 along the threaded path on the connecting screw 3 towards the bottom of the vibration sensor 1, so that the pressure plate 4 drives the sealing ring 5 to be firmly pressed into the sealing groove 7. At this time, the connection end of the connecting screw 3 and the vibration sensor 1 can form a sealing layer through this structure.

[0032] After the sealing structure is established at the connection between the pressure plate 4 and the opening 6, the tightening ring 33 can be adjusted upwards and expanded. This allows the tightening ring 33 to smoothly fit into the annular groove 32 when it reaches the bottom of the sealing sleeve 31. Then, the tightening ring 33 is released, causing it to contract and press the sealing sleeve 31 inwards. The compressed sealing sleeve 31 deforms, causing its inner wall to tightly fit into the threaded groove of the connecting screw 3. This creates a sealing structure at the bottom of the connection between the connecting screw 3 and the pressure plate 4, preventing water or oil stains from penetrating into the vibration sensor 1 through the threaded structure of the connection between the connecting screw 3 and the pressure plate 4.

[0033] The combination of the two sealing mechanisms mentioned above ensures the safety of vibration sensor 1 during use.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
