[0018] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0019] Currently, the connection between existing monitoring equipment and electromechanical equipment is not tight enough. Once the electromechanical equipment is displaced, it will affect the continuity of the monitoring system, causing deviations in the monitoring data and reducing accuracy.

[0020] Therefore, in response to the aforementioned problems, this disclosure provides a vibration monitoring device. The adjustable telescopic structure of the fixed bracket can be flexibly adjusted according to the specifications and installation positions of electromechanical equipment, ensuring a tight fit between the fixed bracket and the electromechanical equipment. First, Figure 1 A schematic diagram of the vibration monitoring device provided by this utility model. Figure 2This is a structural schematic diagram of the fixing bracket provided by this utility model. The following will be combined with... Figure 1 and Figure 2 The vibration monitoring device of this disclosure is described in detail. The vibration monitoring device of this disclosure includes: Fixed brackets and monitoring components; The fixed support includes a horizontal connecting frame and a vertical connecting frame; both ends of the horizontal connecting frame are connected to the vertical connecting frame; both the horizontal connecting frame and the vertical connecting frame adopt an adjustable telescopic structure; The monitoring components include at least one of the following: a vibration sensor and a pressure sensor; the vibration sensor is embedded in a horizontal connecting frame; the pressure sensor is disposed in a vertical connecting frame.

[0021] As shown in Figures 1 and 2: Mark 1 represents the electromechanical equipment to be monitored, Mark 2 represents the fixed support, Mark 21 represents the horizontal connecting frame, Mark 22 represents the vertical connecting frame, and Mark 3 represents the monitoring component.

[0022] The fixed bracket 2 can be enclosed by the top horizontal connecting frame and the two side vertical connecting frames to form a clamping space suitable for the electromechanical equipment 1. Its adjustable telescopic structure can flexibly adjust the enclosure range according to at least one dimension such as the length and height of the electromechanical equipment 1, so that the lower surface of the horizontal connecting frame and the inner side of the vertical connecting frame of the fixed bracket 2 are in close contact with the outer wall of the electromechanical equipment 1. In this way, a stable installation reference can also be provided for the subsequent vibration sensor (the limit seat embedded in the horizontal connecting frame) and pressure sensor (the detection seat mounted on the vertical connecting frame), so as to realize the synchronous displacement of the monitoring components and the electromechanical equipment 1 and accurately capture the vibration state of the equipment.

[0023] When the electromechanical equipment 1 is running, the horizontal connecting frame drives the L-shaped adjusting seat to slide through the first threaded screw rod, adapting to the length of the equipment and keeping the limiting seat (including the vibration sensor) in close contact with the top of the equipment, collecting vertical vibration data in real time; the vertical connecting frame adjusts the relative position of the L-shaped upper connecting frame and the T-shaped lower connecting frame through the threaded column and fastening nut, adapting to the height of the equipment, while the detection seat (including the pressure sensor) adjusts the preload of the top rod through the second threaded screw rod, so that the top rod is in contact with the side wall of the equipment, converting the lateral vibration into a pressure signal for collection.

[0024] The following will combine Figure 3 The horizontal connecting frame of this disclosure is described in detail. Figure 3 A schematic diagram of the structure of the horizontal connecting frame provided by this utility model. The adjustable telescopic structure of the horizontal connecting frame disclosed herein includes: Connecting seat, adjusting seat, first threaded rod and limiting seat; The adjusting seat is fixedly connected to both ends of the connecting seat; The first threaded rod is rotatably connected to the upper side wall of the adjusting seat and is also rotatably connected to the connecting seat; The limiting seat is fixedly connected to the bottom of the connecting seat; the vibration sensor is embedded in the bottom of the limiting seat.

[0025] It should be noted that the connector in this disclosure can be a U-shaped connector; the adjustment seat can be an L-shaped adjustment seat.

[0026] like Figure 3 As shown: Mark 211 is a U-shaped connecting seat, which forms the main frame of the horizontal connecting frame, and guide grooves are opened on the inner walls at both ends; Mark 212 is an L-shaped adjusting seat, which is slidably connected to the connecting seat 211 through the groove and can move telescopically along the length of the connecting seat; Mark 213 is a first threaded rod, one end of which is rotatably connected to the upper side wall of the adjusting seat 212, and the other end passes through the connecting seat 211 and is threadedly engaged with it. When the rod is rotated, the adjusting seat 212 is driven to slide along the groove by means of thread transmission, so as to realize the length adaptation of the horizontal connecting frame; Mark 214 is a limiting seat, which is vertically fixed to the bottom center of the connecting seat 211. The vibration sensor (such as a piezoelectric accelerometer) marked 31 is embedded in its lower surface. When the horizontal connecting frame clamps the electromechanical equipment, the limiting seat 214 and the vibration sensor 31 are synchronously attached to the top of the electromechanical equipment, which can be used to monitor the vertical vibration signal of the equipment.

[0027] The following will combine the above Figure 3 The vertical connecting frame of this disclosure is described in detail. The adjustable telescopic structure of the vertical connecting frame of this disclosure includes: Upper connecting frame, lower connecting frame, threaded column, fastening nut and limiting layer; The upper connecting frame and the lower connecting frame are slidably connected; The threaded column is fixedly installed at the top of the lower connecting frame and extends through the upper connecting frame; The fastening nut is fixedly connected at the top of the threaded column; the limiting layer is fixedly connected on the lower side wall of the lower connecting frame.

[0028] It should be noted that the upper connecting frame of this disclosure can be an L-shaped upper connecting frame; the lower connecting frame can be a T-shaped lower connecting frame.

[0029] As shown in Figure 3: Mark 221 is the L-shaped upper connecting frame, and Mark 222 is the T-shaped lower connecting frame. The two can be vertically slidably connected to flexibly adapt to the height of the electromechanical equipment; Mark 223 is the threaded post, which is vertically fixed to the top of the lower connecting frame 222 and extends upward through the upper connecting frame 221; Mark 224 is the fastening nut, which is threaded to the top of the threaded post 223. After tightening, it abuts against the upper connecting frame 221 and locks the telescopic length of the vertical connecting frame; Mark 225 is the limiting layer, which is integrally formed on the outer side of the lower side wall of the lower connecting frame 222. When clamping the electromechanical equipment, the limiting layer 225 fits against the outer wall of the equipment and can provide auxiliary limiting.

[0030] In embodiments of this disclosure, the lower connecting frame can also be used to further fix the vertical connecting frame, as will be described below. Figure 4 The lower connecting frame further elaborates on this disclosure and includes: Connecting layer, connecting holes, and connecting ropes; The connecting layer is fixedly connected to the bottom of the lower connecting frame; The connection holes are evenly distributed in the connection layer; The connecting rope is placed in the connecting hole and used to fix the connecting layer. Figure 4 Figure 4 shows a schematic diagram of the lower connection structure provided by this utility model. As shown in Figure 4: Mark 22 is the lower connection frame (T-shaped structural section); Mark 23 is the connection layer, which is horizontally fixed to the bottom end of the lower connection frame 22 and is in the shape of an outwardly extending flat plate; Mark 24 is the connection hole, which is evenly opened on the side wall of the connection layer 23 (it can be arranged at equal intervals); Mark 25 is the connection rope (which can be made of wear-resistant material, such as plastic-coated steel wire rope), which is inserted into the connection hole 24 on both sides of the connection layer. Even if the electromechanical equipment is displaced due to vibration, the tension can offset the risk of loosening and ensure that the fixed bracket and the electromechanical equipment are always tightly fitted.

[0031] The following will combine Figure 5 The monitoring components of this disclosure are described in detail. Figure 5 A schematic diagram of the monitoring component provided by this utility model. The monitoring component disclosed herein also includes: Detection seat, push rod, spring, second threaded screw; The detection seat is slidably connected to the vertical connecting frame. The pressure sensor is fixedly connected to the upper side wall of the detection base; The top rod slides through and connects to the vertical connecting frame. The spring is set on the surface of the push rod; The second threaded rod is fixedly connected to the lower side wall of the testing seat and is rotatably connected to the vertical connecting frame.

[0032] As shown in Figure 5: Mark 32 is a T-shaped detection seat, which runs longitudinally through the vertical connecting frame 22 and forms a sliding fit through the guide groove; Mark 33 is an I-shaped push rod, which runs laterally through the vertical connecting frame 22, with one end facing the side wall of the electromechanical equipment and the other end abutting against the detection seat 32; Mark 34 is a spring, which is sleeved on the surface of the push rod 33 and clamped between the inner wall of the vertical connecting frame and the limit boss of the push rod to realize impact buffering and automatic reset; Mark 35 is a second threaded screw rod, the lower end of which is threaded to the lower side wall of the detection seat 32, and the upper end is rotatably fitted to the vertical connecting frame 22 through a bearing seat. Twisting can drive the detection seat 32 to slide vertically and adjust the preload of the push rod on the equipment; Mark 36 is a pressure sensor, which is fixed to the upper side wall of the detection seat 32. When the electromechanical equipment vibrates laterally, the push rod 33 squeezes the spring 34 and pushes the detection seat 32 upward. The pressure sensor 36 indirectly restores the lateral vibration parameters of the equipment by collecting the pressure change of the detection seat.

[0033] The monitoring components of this disclosure are described in detail below: the vibration sensor is a piezoelectric accelerometer; the pressure sensor is a strain gauge pressure sensor. The piezoelectric accelerometer's measurement range and sensitivity can be flexibly set at least one. When embedded in the bottom of the horizontal connecting frame's limiting seat, its sensing end face is flush with the lower surface of the limiting seat, ensuring a tight fit with the outer wall of the electromechanical equipment, and accurately capturing the vertical vibration acceleration signal during equipment operation. The strain gauge pressure sensor's range and accuracy can be flexibly set at least one. When fixed to the upper side wall of the detection seat, it can be rigidly connected to the detection seat via a metal elastomer, converting the lateral vibration pressure transmitted by the top rod into an electrical signal for measurement.

[0034] The monitoring components also include: Protective housings are installed on the outside of both the vibration and pressure sensors. These housings can be made of transparent polycarbonate, offering impact resistance and resistance to high and low temperatures. This allows staff to easily observe the sensor installation status while protecting them from contamination during equipment operation.

[0035] The following details the material of the fixing bracket disclosed herein: The fixed bracket is made of at least one of the following materials: carbon fiber composite material or alloy material. Carbon fiber composite material, compared to traditional steel, can reduce the additional load on electromechanical equipment and also possesses excellent corrosion resistance. For alloy materials, aluminum alloy or titanium alloy are preferred to resist wear caused by long-term vibration and friction.

[0036] In this utility model, during installation, the first threaded rod 213 can be rotated to drive the adjusting seat 212 to slide, and the horizontal connecting frame 21 can be unfolded according to the length of the electromechanical equipment 1, so that the fixed bracket 2 can be installed on the outside of the electromechanical equipment 1. Then, the first threaded rod 213 is rotated in the opposite direction to drive the adjusting seat 212 to retract into the connecting seat 211, so that the vertical connecting frame 22 fits against the outer wall of the electromechanical equipment 1. By sliding the upper connecting frame 221 and the T-shaped lower connecting frame 222, the length of the vertical connecting frame 22 can be adjusted according to the height of the electromechanical equipment 1. Then, the fastening thread is rotated until it abuts against the upper connecting frame 221, so that the horizontal connecting frame 21 and the vertical connecting frame 22 clamp the upper and lower ends of the electromechanical equipment 1, while fixing the length of the vertical connecting frame 22, so that the fixed bracket 2 is stuck on the outside of the electromechanical equipment 1, and the monitoring component 3 is stably connected to the electromechanical equipment 1.

[0037] Vertical vibration monitoring is performed by closely attaching the vibration sensor 31 to the electromechanical equipment 1. By rotating the second threaded rod 35, the detection seat 32 is slid, so that one end of the top rod 33 abuts against the side wall of the electromechanical equipment 1. When the electromechanical equipment 1 vibrates laterally, the top rod 33 can transmit the magnitude of the change in force to the pressure sensor 36, thereby monitoring the change in lateral vibration of the electromechanical equipment 1. By monitoring the vibration of the electromechanical equipment 1 in different directions in two ways, the comprehensiveness of the monitoring data is improved.
