Technical Field
[0001] This utility model relates to the field of energy storage spherical tanks, and in particular to a fatigue monitoring device for compressed air energy storage spherical tanks. Background Technology
[0002] Compressed air energy storage spherical tanks are gas storage devices that store high-pressure air generated by compressing electrical energy during off-peak hours, converting electrical energy into air potential energy. During peak hours, the high-pressure air is released to drive an expander to generate electricity, feeding the potential energy back to the grid. This achieves peak shaving and valley filling of electricity and efficient energy dispatch and management. Compressed air energy storage spherical tanks need to be equipped with fatigue monitoring devices because they are subjected to frequent periodic pressurization and depressurization during operation. This alternating load can easily induce metal fatigue, leading to the initiation and propagation of micro-cracks. Through real-time monitoring, potential defects can be detected in time, fatigue fracture accidents can be prevented, and the long-term safe and stable operation of the equipment can be guaranteed.
[0003] Traditional energy storage spherical tanks are difficult and limited in fatigue monitoring, relying heavily on manual tools. This leads to unnecessary waste of human resources and time, and increases the workload of staff. Furthermore, since the tanks are placed outdoors, dust easily adheres to their surfaces, obscuring the outer walls. When staff use tools for monitoring, the dust can cover cracks, resulting in inaccurate monitoring results.
[0004] Therefore, those skilled in the art have provided a fatigue monitoring device for compressed air energy storage spherical tanks to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fatigue monitoring device for compressed air energy storage spherical tanks. A first motor and a second motor drive a first limiting block to retract, causing the monitor to move up and down. A first sliding block causes a first arc-shaped slide rail to slide inside a second arc-shaped slide rail. A fourth motor drives the monitoring mechanism to perform circumferential motion. This mechanism allows for comprehensive monitoring of the spherical tank, improving worker efficiency and making their work more convenient.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A fatigue monitoring device for a compressed air energy storage spherical tank includes a third protective shell. A fourth motor is fixedly connected inside the third protective shell. A monitoring mechanism is provided on one outer wall of the fourth motor. The monitoring mechanism includes an arc-shaped outer shell fixedly connected to the output end of the fourth motor. A second arc-shaped slide rail is fixedly connected to the inner wall of the arc-shaped outer shell. A first sliding block is sleeved on the outer wall of the second arc-shaped slide rail. A first protective shell is fixedly connected to one outer wall of the first sliding block. A chain is provided inside the first protective shell. A second limiting ring is fixedly connected to the end of the chain away from the first limiting ring. A first motor is fixedly connected to the inner wall of the first protective shell. A first arc-shaped slide rail is fixedly connected to one outer wall of the first sliding block. A second protective shell is fixedly connected to the end of the first arc-shaped slide rail away from the first protective shell. A monitoring instrument is sleeved on the outer wall of the first arc-shaped slide rail. A second motor is provided inside the second protective shell. A cleaning mechanism is provided on the outer wall of the fourth motor on the side away from the monitoring mechanism. The cleaning mechanism includes a third arc-shaped slide rail fixedly connected to the output end of the fourth motor. A second limiting block is fixedly connected to the inner wall of the third arc-shaped slide rail. A second sliding block is slidably connected to the outer wall of the second limiting block. A third motor is fixedly connected to the inner wall of the second sliding block. A brush head is fixedly connected to the output end of the third motor. Through the above technical solution, the first motor and the second motor drive the first limit block to rewind, causing the monitor to move up and down. The first sliding block causes the first arc-shaped slide rail to slide inside the second arc-shaped slide rail. The fourth motor drives the monitoring mechanism to make circumferential movements. This mechanism allows the monitoring mechanism to monitor the spherical tank from all angles, improving the work efficiency and convenience of the staff. The second sliding block drives the brush head to slide and clean the surface of the spherical tank, avoiding misjudgments caused by dust during monitoring, avoiding unnecessary time waste, and improving the work efficiency of the staff. The second sliding block drives the brush head to slide on the third arc-shaped slide rail, which can increase the cleaning area of the brush head and make the monitoring results more accurate.
[0007] Furthermore, the first arc-shaped slide rail has a groove inside, and the outer walls on both sides of the chain are fixedly connected with first limiting blocks, which slide inside the groove. The above technical solution allows the chain to be better fixed and limited by sliding the first limiting blocks on both sides of the chain within the groove inside the first arc-shaped slide rail, making it less likely to fall off during the sliding process.
[0008] Furthermore, the first sliding block is fixedly connected to the first arc-shaped slide rail; The above technical solution can fix the first sliding block by the first arc-shaped slide rail, which can prevent displacement and ensure normal operation. It can also make the sliding of the first arc-shaped slide rail smoother.
[0009] Furthermore, the monitoring device is fixedly connected to the chain; The above technical solution allows the chain to tighten or loosen, causing the monitoring instrument to slide, enabling comprehensive monitoring of the spherical tank and reducing the limitations of the monitoring angle.
[0010] Furthermore, the first arc-shaped slide rail slides on the inner wall of the second arc-shaped slide rail; The above technical solution enables the first arc-shaped slide rail to slide inside the second arc-shaped slide rail, allowing the first arc-shaped slide rail to monitor the upper and lower hemispheres of the spherical tank separately, thereby expanding the monitoring angle and range and making the monitoring results more accurate.
[0011] Furthermore, a spherical tank is fixedly connected to the lower surface of the fourth motor, and a plurality of first support columns are fixedly connected to the lower end of the outer wall of the spherical tank; The above technical solution enables the fourth motor to be fixed by the spherical tank, and the spherical tank to be fixed by the first support column, making the spherical tank more stable and less prone to displacement, and also enabling the fourth motor to operate normally.
[0012] Furthermore, the outer wall of the spherical tank is provided with a guide rail, and a plurality of second support columns are fixedly connected to the lower surface of the guide rail. The lower ends of the third arc-shaped slide rail and the arc-shaped outer shell slide inside the guide rail. The above technical solution allows the guide rail to be fixed by the second support column, making it less prone to displacement. It also allows the third arc-shaped slide rail and the arc-shaped outer shell to slide inside the guide rail, and allows the guide rail to provide support for the third arc-shaped slide rail and the arc-shaped outer shell.
[0013] Furthermore, the lower surface of the brush head is in close contact with the outer wall of the spherical tank; The above technical solution enables the brush head to clean the outer wall of the spherical tank via a third motor, making the monitoring data more accurate and less susceptible to the influence of dust.
[0014] This utility model has the following beneficial effects: 1. The present invention proposes a fatigue monitoring device for compressed air energy storage spherical tanks. The first motor and the second motor drive the first limiting block to rewind, causing the monitoring instrument to move up and down. The first sliding block causes the first arc-shaped slide rail to slide inside the second arc-shaped slide rail. The fourth motor drives the monitoring mechanism to make circumferential motion. This mechanism enables the monitoring mechanism to monitor the spherical tank from all directions, which can improve the work efficiency of the staff and make the work more convenient.

[0018] 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.
[0019] One embodiment of this utility model is provided: Reference Figure 1 , Figure 3 and Figure 6 A fatigue monitoring device for a compressed air energy storage spherical tank includes a third protective shell 8. A fourth motor 7 is fixedly connected inside the third protective shell 8. A monitoring mechanism 2 is provided on one outer wall of the fourth motor 7. The monitoring mechanism 2 includes an arc-shaped outer shell 202 fixedly connected to the output end of the fourth motor 7. A second arc-shaped slide rail 2013 is fixedly connected to the inner wall of the arc-shaped outer shell 202. A first sliding block 203 is sleeved on the outer wall of the second arc-shaped slide rail 2013. A first protective shell 201 is fixedly connected to one outer wall of the first sliding block 203. The internal part of the first protective shell 201 is provided with a chain 209. The end of the chain 209 away from the first limiting ring 207 is fixedly connected to a second limiting ring 2011. The inner wall of the first protective shell 201 is fixedly connected to a first motor 208. The outer wall of one side of the first sliding block 203 is fixedly connected to a first arc-shaped slide rail 204. The end of the first arc-shaped slide rail 204 away from the first protective shell 201 is fixedly connected to a second protective shell 206. The outer wall of the first arc-shaped slide rail 204 is fitted with a monitoring instrument 205. The second protective shell 206 is provided with a second motor 2012 inside. A cleaning mechanism 3 is provided on the outer wall of the fourth motor 7 away from the monitoring mechanism 2. The cleaning mechanism 3 includes a third arc-shaped slide rail 301 fixedly connected to the output end of the fourth motor 7. A second limiting block 303 is fixedly connected to the inner wall of the third arc-shaped slide rail 301. A second sliding block 304 is slidably connected to the outer wall of the second limiting block 303. A third motor 305 is fixedly connected to the inner wall of the second sliding block 304. A brush head 302 is fixedly connected to the output end of the third motor 305. Through the above technical solution, the first motor 208 and the second motor 2012 drive the first limiting block 2010 to rewind, causing the monitor 205 to move up and down. The first sliding block 203 causes the first arc-shaped slide rail 204 to slide inside the second arc-shaped slide rail 2013. The fourth motor 7 drives the monitoring mechanism 2 to perform circumferential motion. This mechanism allows the monitoring mechanism 2 to monitor the spherical tank 1 from all angles, improving the work efficiency and convenience of the staff. The second sliding block 304 drives the brush head 302 to slide and clean the surface of the spherical tank 1, avoiding misjudgments caused by dust during monitoring, avoiding unnecessary time waste, and improving the work efficiency of the staff. The second sliding block 304 drives the brush head 302 to slide on the third arc-shaped slide rail 301, which can increase the cleaning area of the brush head 302 and make the monitoring results more accurate.
[0020] Reference Figure 4 , Figure 5 and Figure 7 The first arc-shaped slide rail 204 has a groove 2014 inside. The outer walls of both sides of the chain 209 are fixedly connected to the first limiting blocks 2010. The first limiting blocks 2010 slide inside the groove 2014. By sliding the first limiting blocks 2010 on both sides of the chain 209 in the groove 2014 inside the first arc-shaped slide rail 204, the chain 209 can be better fixed and limited, and it is not easy to fall off during the sliding process. The first sliding block 203 is fixedly connected to the first arc-shaped slide rail 204, so that the first sliding block 203 can be fixed by the first arc-shaped slide rail 204, which can prevent displacement and ensure normal operation. It can also make the sliding of the first arc-shaped slide rail 204 smoother.
[0021] Reference Figure 3 , Figure 5 and Figure 6 The monitor 205 is fixedly connected to the chain 209, which can cause the monitor 205 to slide by tightening or loosening the chain 209. This allows for all-around monitoring of the spherical tank 1, reducing the limitation of the monitoring angle. The first arc-shaped slide rail 204 slides on the inner wall of the second arc-shaped slide rail 2013, allowing the first arc-shaped slide rail 204 to slide inside the second arc-shaped slide rail 2013. This enables the first arc-shaped slide rail 204 to monitor the upper and lower hemispheres of the spherical tank 1 separately, expanding the monitoring angle and range, and making the monitoring results more accurate.
[0022] Reference Figure 2 , Figure 3 and Figure 8The lower surface of the fourth motor 7 is fixedly connected to the spherical tank 1. Multiple first support columns 4 are fixedly connected to the lower end of the outer wall of the spherical tank 1. This allows the fourth motor 7 to be fixed via the spherical tank 1, making the spherical tank 1 more stable and less prone to displacement, and ensuring the normal operation of the fourth motor 7. A guide rail 6 is provided on the outer wall of the spherical tank 1. Multiple second support columns 5 are fixedly connected to the lower surface of each guide rail 6. The lower ends of the third arc-shaped slide rail 301 and the arc-shaped outer shell 202 are both located on the guide rail 6. The internal sliding mechanism allows the guide rail 6 to be fixed by the second support column 5, preventing displacement. This allows both the third arc-shaped slide rail 301 and the arc-shaped outer shell 202 to slide inside the guide rail 6. The guide rail 6 also provides support for the third arc-shaped slide rail 301 and the arc-shaped outer shell 202. The lower surface of the brush head 302 is in close contact with the outer wall of the spherical tank 1, allowing the brush head 302 to clean the outer wall of the spherical tank 1 via the third motor 305. This makes the monitoring data more accurate and less susceptible to the influence of dust.
[0023] Working principle: When the device is needed, the fourth motor 7 drives the third arc-shaped slide rail 301 to rotate, causing the second sliding block 304 to drive the brush head 302 to slide on the third arc-shaped slide rail 301 to clean the spherical tank 1. After cleaning, the fourth motor 7 drives the monitoring mechanism 2 to rotate on the surface of the spherical tank 1, and the monitoring instrument 205 monitors the surface of the spherical tank 1. When the angle needs to be adjusted, the first motor 208 or the second motor 2012 is turned on, causing the chain 209 to retract by winding around the first limit ring 207 or the second limit ring 2011. This causes the chain 209 to retract, thereby moving the monitoring instrument 205 to monitor the upper half of the sphere. After the upper half is monitored, the first sliding block 203 causes the first arc-shaped slide rail 204 to slide inside the second arc-shaped slide rail 2013 to monitor the lower half of the sphere. Then, by turning on the first motor 208 or the second motor 2012, the chain 209 retracts by wrapping around the first limiting ring 207 or the second limiting ring 2011, thereby causing the chain 209 to retract, thereby moving the monitoring instrument 205 to monitor the lower half of the sphere.
[0024] The arc-shaped guide rail, through the cooperation of a precision-machined arc-shaped track and a slider with internal circulating balls, transforms the linear traction force provided by the motor into smooth rolling motion along a fixed arc path; the balls circulate infinitely within the slider, transforming sliding friction into low-resistance rolling friction, thereby guiding the load to move precisely and smoothly along a predetermined arc trajectory. By moving along the arc trajectory, the first arc-shaped guide rail 204 can slide inside the second arc-shaped guide rail 2013.
