Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a device for monitoring the operating status of power plant equipment. Background Art

[0002] Power plant operation status monitoring is one of the key industrial automation applications, which aims to ensure the normal operation of the power plant, improve efficiency, ensure safety, and promptly identify and solve potential problems. It can also help power plant managers make corresponding decisions, improve production efficiency, and reduce maintenance costs.

[0003] In the prior art, people often monitor the various operating conditions of power plant equipment through a large digital display screen and judge the operating status of the equipment based on the displayed data.

[0004] However, in actual use, since the existing display screen is often fixed in a designated position when in use, or it is hung on a track for people to move and review, it is often necessary to manually add lubricating oil between the track and the pulley for maintenance after long-term use, so as to reduce the friction between the pulley block and the track. The slide rail is often installed at a high place, so its maintenance process is inconvenient. At the same time, when the digital display screen is impacted or collided by external force, the impact force is often directly borne by its installation frame, so that the digital display screen and its frame are prone to plastic deformation, thereby affecting its normal use. In view of this, we propose a power plant equipment operation status monitoring device. Utility Model Content

[0005] The main purpose of the utility model is to provide a device for monitoring the operating status of power plant equipment, which solves the problems mentioned in the above background technology.

[0006] To achieve the above purpose, the utility model proposes a power plant equipment operation status monitoring device, including a monitoring screen, a buffer device is arranged on the back of the monitoring screen, a connecting rod is arranged on the back of the buffer device, a pulley seat is fixedly connected to the upper end of the connecting rod, a guide rail is contacted at the pulley of the pulley seat, and an oil supply device is arranged on the upper end of the guide rail;

[0009] Preferably, the connecting rod is arranged in an L shape, the upper end of the pulley seat is rotatably connected to a plurality of pulleys, and rectangular grooves are provided on both sides of the guide rail.

[0010] Preferably, a plurality of through holes are provided at the lower end of the oil tank, through holes are provided at the side surface of the oil tank, and a through hole is provided at the upper end of the oil tank.

[0011] Preferably, a through hole is provided at the center of the inner surface of the oil tank, and the center of the inner surface of the oil tank is divided into two parts by a partition.

[0012] Preferably, the outer arc surface of the trigger block is slidably connected to the oil tank, the upper end of the piston plate is elastically connected to the oil tank via a spring, and the lower end of the trigger block is set as an arc surface.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) When the power plant equipment operation status monitoring device is in use, it is necessary to push the monitoring screen to slide to the leftmost or rightmost side of the guide rail. At this time, the pulley seat will contact the trigger blocks on both sides during the movement, so that it can drive the upper piston plate to move upward as a whole. At this time, the piston plate will squeeze the air on the left side of the oil tank to the right side during the movement. At this time, the internal pressure on the right side of the oil tank will increase accordingly, so that the pressure relief valve can be opened and the lubricating oil on the right side of the oil tank can be discharged downward, so that it can fall into the pulley, thereby completing the automatic lubrication maintenance process.

[0017] (2) When the power plant equipment operation status monitoring device is impacted by external force, the monitoring screen will squeeze the elastic telescopic rod on the back, so that the elastic telescopic rod can buffer the impact force through its own elastic deformation ability. In addition, during the movement of the elastic telescopic rod, the piston rod will also be squeezed to move into the fixed bin. At this time, since the fixed bin is filled with damping fluid, the damping fluid will hinder the movement of the piston rod. At the same time, since a plurality of through holes are provided at the end of the piston rod, the damping fluid will not completely block its movement. Therefore, the device can reduce the damage to the monitoring screen when it is impacted through damping and buffering. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-4 The utility model provides a technical solution: a power plant equipment operation status monitoring device, including a monitoring screen 6, the internal processor of the monitoring screen 6 is based on the existing SIS report system, so that it can record the frequent start and stop data of the peak-shaving unit, and read the start and stop time nodes of the main and auxiliary equipment, generate a report and transmit it to the SIS system, the production management personnel and the operation personnel can perform operation supervision and operation adjustment according to the table displayed on the monitoring screen 6, and further realize the lean management of production, the back of the monitoring screen 6 is provided with a buffer device 3, the back of the buffer device 3 is provided with a connecting rod 5, the upper end of the connecting rod 5 is fixedly connected with a pulley seat 4, the pulley of the pulley seat 4 is in contact with a guide rail 1, and the upper end of the guide rail 1 is provided with an oil supply device 2;

[0028] The oil supply device 2 includes an oil tank 203, the upper end of which is fixedly connected with a feed port 201, and the feed port 201 can be sealed by a cover plate when not in use to prevent air leakage on the right side of the oil tank 203, the inner surface piston of the oil tank 203 is connected with a piston plate 204, the lower end of the piston plate 204 is fixedly connected with a trigger block 205, the lower end of the oil tank 203 is fixedly connected with a pressure relief valve 206, the outer surface of the oil tank 203 is fixedly connected to the guide rail 1, and the upper end of the inner surface of the oil tank 203 is fixedly connected with a one-way valve 202, and the one-way air intake direction of the one-way valve 202 is one-way to the right side, so that the air on the left side of the oil tank 203 can only be squeezed into the right side in one direction, and cannot flow back.

[0029] Specifically, the connecting rod 5 is set to be L-shaped, so that it can simultaneously connect the pulley seat 4 at the upper end and the connecting seat 301 at the lower end. The upper end of the pulley seat 4 is rotatably connected to multiple groups of pulleys, so that when the pulleys slide in the grooves on both sides of the guide rail 1, they can drive the entire device to move, thereby facilitating the user to observe the data on the monitoring screen 6 from multiple angles. Rectangular grooves are provided on both sides of the guide rail 1, and multiple groups of through holes are provided at the lower end of the oil tank 203, so that it can be connected to the pressure relief valve 206 and the trigger block 205. A through hole is provided on the side surface of the oil tank 203, so that the outside air will be able to enter the left side of the oil tank 203 through the through hole, thereby To replenish the air squeezed to the right side of the oil tank 203 by the piston plate 204, a through hole is provided at the upper end of the oil tank 203, so lubricating oil can be added to the interior of the device through the through hole. A through hole is provided at the center of the inner surface of the oil tank 203, so a one-way valve 202 can be installed. The center of the inner surface of the oil tank 203 is divided into two parts by a partition. The outer arc surface of the trigger block 205 is slidably connected to the oil tank 203. The upper end of the piston plate 204 is elastically connected to the oil tank 203 by a spring. Therefore, when the trigger block 205 is not squeezed, the spring can push the trigger block 205 downward due to its own elastic force, and the lower end of the trigger block 205 is set to an arc surface.

[0030] In the embodiment of the utility model, the buffer device 3 includes a connecting seat 301, the back of the connecting seat 301 is fixedly connected to the connecting rod 5, a rubber pad 302 is fixedly connected to the front surface of the connecting seat 301, elastic telescopic rods 303 are fixedly connected to the inner surface of the connecting seat 301, a fixed bin 305 is fixedly connected to the center of the inner surface of the connecting seat 301, and the inner surface piston of the fixed bin 305 is connected to the piston rod 304. Damping fluid is stored in the fixed bin 305, so when it is squeezed by the piston rod 304, the movement of the piston rod 304 can be hindered by the properties of the damping fluid itself.

[0031] Specifically, multiple groups of rectangular grooves are provided around the connecting base 301, and multiple groups of through holes are provided on the inner surface of the connecting base 301, so that it can be connected with multiple groups of elastic telescopic rods 303. Multiple groups of elastic telescopic rods 303 are provided, and the multiple groups of elastic telescopic rods 303 are distributed in a circular array with the center of the connecting base 301 as the array center. The end of the elastic telescopic rod 303 away from the connecting base 301 is fixedly connected to the monitoring screen 6, and the inner surface of the fixed chamber 305 is elastically connected to the piston rod 304 through a spring. Therefore, after the monitoring screen 6 is impacted, the spring can push the piston rod 304 to extend again through its own elastic force and reset the position of the piston rod 304. The end of the piston rod 304 away from the fixed chamber 305 is fixedly connected to the monitoring screen 6.

[0032] When working (or in use), it is necessary to push the monitoring screen 6 to slide it to the leftmost or rightmost side of the guide rail 1. At this time, the pulley seat 4 will contact the trigger blocks 205 on both sides during the movement, so that it can drive the upper piston plate 204 to move upward as a whole. At this time, the piston plate 204 will squeeze the air on the left side of the oil tank 203 to the right side during the movement. At this time, the internal pressure on the right side of the oil tank 203 will increase accordingly, so that the pressure relief valve 206 can be opened and the lubricating oil on the right side of the oil tank 203 can be discharged downward, and it can fall into the pulley, thereby completing the automatic lubrication maintenance process; in addition, after the lubrication is completed, the pulley seat 4 will be pushed away from the trigger block 205. At this time, the elastic force of the spring will push the piston plate 204 and the trigger block 205 downward, so that the outside air can enter through the through hole on the left side of the oil tank 203 and restore the air pressure on the left side of the oil tank 203.

[0033] At the same time, when the device is impacted by external force, the monitoring screen 6 will squeeze the elastic telescopic rod 303 on the back, so that the elastic telescopic rod 303 can buffer the impact force through its own elastic deformation ability. In addition, during the movement of the elastic telescopic rod 303, the piston rod 304 will also be squeezed and move toward the inside of the fixed compartment 305. At this time, since the fixed compartment 305 is filled with damping fluid, the damping fluid will hinder the movement of the piston rod 304. At the same time, since a plurality of groups of through holes are provided at the end of the piston rod 304, the damping fluid will not completely block its movement, so that the device can reduce the damage to the monitoring screen 6 when it is impacted through damping and buffering.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
