Description

Technical Field

[0001] This utility model relates to the field of acoustic vibration temperature sensor technology, and more specifically, to a multi-parameter integrated acoustic vibration temperature sensor device for a coal mill. Background Technology

[0002] The multi-parameter integrated acoustic, vibration, and temperature sensor is an intelligent monitoring terminal specifically designed for rotating machinery such as coal mills. It integrates three different types of sensing elements into a compact housing, enabling simultaneous and synchronous acquisition of sound (acoustic signature), vibration, and temperature signals during equipment operation.

[0003] However, the acoustic vibration temperature sensor does not have a waterproof structure. Due to the high humidity environment and corrosive coal dust at the coal mill site, it is very easy for the sensor to penetrate into the inside of the sensor through the structural gaps. This will not only directly cause the internal precision circuit to short-circuit and fail, but the acidic environment formed by the sulfides it contains when it comes into contact with water will also continue to corrode the shell and interface metal, significantly shortening the equipment life. At the same time, since the acoustic vibration temperature sensor is in a vibrating environment for a long time, its power cord interface lacks an effective anti-loosening design, which makes it very easy to fall off during use, causing monitoring interruption.

[0004] Therefore, a multi-parameter integrated acoustic, vibration, and temperature sensor device for coal mills is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-parameter integrated acoustic, vibration and temperature sensor device for coal mills to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-parameter integrated acoustic vibration and temperature sensor device for a coal mill, comprising an acoustic vibration and temperature sensor and a power cord, wherein a connecting block is fixedly connected to one end of the acoustic vibration and temperature sensor, the surface of the acoustic vibration and temperature sensor is provided with a waterproof mechanism for improving the waterproofness of the device, and the surface of the connecting block is provided with a fixing mechanism to prevent the power cord from falling off during use.

[0007] Preferably, the waterproof mechanism includes a first protective shell, a second protective shell, a slider, a groove, a sealing strip, a locking block, a locking slot, a screw hole, and a screw. The first protective shell is slidably connected to one side of the surface of the acoustic vibration temperature sensor, and the second protective shell is slidably connected to the other side. Two sets of sliders are fixedly connected to one side of the first protective shell, and two sets of grooves are opened on one side of the second protective shell. The inner wall of the groove cooperates with the slider.

[0008] Preferably, one end of the first protective shell and the second protective shell are provided with a sealing strip, and the other end of each is fixedly connected with a locking block. The surface of the acoustic vibration temperature sensor is provided with a locking groove, and the inner wall of the locking groove is provided with a sealing gasket. The inner wall of the locking groove cooperates with the locking block.

[0009] Preferably, the surface of the second protective shell has multiple sets of screw holes, and the inner wall of the screw holes is threaded with screws, one end of which cooperates with the slider.

[0010] Preferably, the fixing mechanism includes a limiting groove, a fixing groove, a connector, a groove, a limiting block, a sliding rod, a spring, and a fixing block. The surface of the connector has a limiting groove, the bottom of the connector has a fixing groove, the connector is slidably connected to the surface of the connector, one end of the connector is fixedly connected to a power cord, and a connecting groove is formed between the connector and the power cord.

[0011] Preferably, one end of the connector is provided with a groove, the inner wall of the groove is provided with a limiting block, the inner wall of the groove cooperates with the connecting block, and the inner wall of the limiting groove cooperates with the limiting block.

[0013] Preferably, the bottom of both the first protective shell and the second protective shell is fixedly connected to a positioning plate, and the surface of the positioning plate is provided with two sets of positioning holes.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with the existing technology, the waterproof mechanism involves placing the first and second protective shells onto the acoustic vibration and temperature sensor, inserting the slider into the slide groove, inserting the locking block into the locking slot, and inserting the sealing strip into the connecting groove. Then, the screw is tightened, and the screw passes through the screw hole and is threadedly connected to the slider, so that the first and second protective shells can be fixed on the acoustic vibration and temperature sensor, thereby enclosing the acoustic vibration and temperature sensor and the connector. The protective shells form a protective barrier, preventing water from entering the acoustic vibration and temperature sensor during use and preventing corrosion at the interface, thus avoiding water entering the acoustic vibration and temperature sensor and affecting the use of the device.

[0016] 2.
