Description

Technical Field

[0001] The present invention relates to the technical field of substation vibration reduction, and particularly to a vibration and shock dual-control device for a reactor. Background Art

[0002] In a substation system, as an important electrical device, the stable operation of a reactor is crucial for ensuring the safety and reliability of the power system. However, the reactor generates certain vibrations during operation, which not only affect the performance and lifespan of the device itself, but may also cause damage to surrounding buildings and structures. Especially in earthquake-prone areas, the superimposed effect of earthquake vibrations and the device's own vibrations may exacerbate the degree of device damage, and even lead to device failure, posing a serious threat to the normal operation of the power system.

[0003] Currently, in traditional technologies, in order to control the vibrations of a reactor, some fixed shock-absorbing measures are usually adopted, such as setting shock pads, adding support structures, etc. However, these measures often have problems such as inconvenient installation, difficult adjustment, and limited shock-absorbing effects. At the same time, these measures can often only control the vibrations of the reactor in the horizontal or vertical directions. Traditional shock-absorbing measures are difficult to meet the vibration reduction requirements of reactor equipment in earthquake-prone areas, resulting in increased device damage and thus reduced service life of the device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that traditional shock-absorbing measures are difficult to meet the vibration reduction requirements of reactor equipment in earthquake-prone areas, resulting in increased device damage and thus reduced service life of the device.

[0005] In order to solve the above technical problems, the present invention provides a dual-vibration control device for a reactor, which includes a guide rail, a vertical elastic vibration reduction mechanism, a sleeper and a horizontal friction vibration reduction mechanism. The guide rail is arranged below the reactor to assist the reactor in vibration reduction; one end of the vertical elastic vibration reduction mechanism is connected to the reactor, and the other end is connected to the guide rail. The vertical elastic vibration reduction mechanism includes an inclined rod, an elastic component and a fixed component. The fixed component is arranged on the guide rail. The number of elastic components is at least two. The elastic components are respectively arranged at both ends of the fixed component. The elastic component is connected to the inclined rod. The end of the inclined rod facing away from the elastic component is connected to the reactor. The reactor is vertically connected to the guide rail. During displacement, the end of the driving diagonal rod close to the elastic component moves closer to or farther from each other, thereby driving the elastic component to reciprocate along the length direction of the guide rail. The elastic component is used to absorb and release the vibration force generated by the reactor; the sleeper is arranged horizontally below the guide rail to support the guide rail; one end of the horizontal friction vibration reduction mechanism is connected to the guide rail, and the other end is connected to the sleeper. The horizontal friction vibration reduction mechanism includes a steel plate layer and a friction damping layer. One end of the steel plate layer is connected to the guide rail, and the other end is connected to the friction damping layer. When the vibration of the reactor drives the guide rail to vibrate, relative movement is generated between the steel plate layer and the friction damping layer, thereby forming friction damping to absorb the vibration force generated by the reactor.

[0006] In one embodiment, the elastic components include a sliding member and a spring member, one end of the spring member facing away from the fixed member is connected to the sliding member, the sliding member is arranged on the guide rail, and the sliding member reciprocates on the guide rail along the length direction of the guide rail, the one end of the sliding member facing away from the guide rail is connected to the inclined rod, and when the sliding member reciprocates on the guide rail along the length direction of the guide rail, the spring member is used to absorb and release the force generated by the reciprocating movement of the sliding member.

[0007] In one embodiment, the sliding member includes a slider and a steel ball. The slider is arranged above the guide rail, and a groove is arranged between the slider and the guide rail, which is concave in the direction away from the guide rail. The steel ball is arranged in the groove. The steel ball is rollingly connected to the guide rail in the groove. The steel ball is used to convert the sliding friction between the slider and the guide rail into rolling friction.

[0008] In one embodiment, there are multiple steel balls, which are arranged at intervals along the length direction of the groove, and a lubricating layer is arranged on the outside of each steel ball.

[0009] In one embodiment, the fixing assembly includes a first fixing block and a second fixing block, the first fixing blocks are respectively arranged at both ends of the guide rail, the first fixing block is located above the sleeper, and the first fixing block is fixedly connected to the sleeper through a fastener, the second fixing block is arranged above the guide rail, the second fixing block wraps the guide rail, and the two ends of the second fixing block are respectively connected to the first fixing block.

[0010] In one embodiment, the steel plate layer includes an upper steel plate, a main steel plate, and a lower steel plate that are sequentially arranged at intervals from top to bottom in the vertical direction. The upper steel plate is connected to the guide rail by fasteners, the main steel plate is connected to the sleeper by inserting steel sheets on the plate body into the sleeper, and the lower steel plate is connected to the ground by steel spines on the plate body.

[0011] In one embodiment, the friction damping layer includes a first friction plate. One end of the first friction plate is connected to the upper steel plate, and the other end is connected to the main steel plate. The first friction plate is used to limit the displacement of the upper steel plate and the main steel plate in the horizontal direction.

[0012] In one embodiment, the friction damping layer further includes a second friction plate. The second friction plate is arranged at an interval from the first friction plate in the vertical direction. One end of the second friction plate is connected to the main steel plate, and the other end is connected to the lower steel plate. The second friction plate is used to limit the displacement of the main steel plate and the lower steel plate in the horizontal direction.

[0013] In one embodiment, the number of guide rails is at least two. The two guide rails are arranged at intervals in the horizontal direction, and each guide rail is arranged vertically. The number of sleepers is at least three, and the three sleepers are arranged horizontally below the guide rails in the horizontal direction.

[0014] In one embodiment, the number of vertical elastic damping mechanisms and horizontal friction damping mechanisms is multiple, and the multiple vertical elastic damping mechanisms and horizontal friction damping mechanisms are respectively arranged at the four corners of the reactor.

[0015] Further, the fasteners are fixing bolts and fixing nuts.

[0016] Compared with the prior art, the beneficial effects of the shock and vibration dual-control device for a reactor in an embodiment of the present invention are as follows: The guide rail is arranged below the reactor. The guide rail assists the reactor in vibration reduction and provides an installation basis for the vertical elastic vibration reduction mechanism and the horizontal friction vibration reduction mechanism. One end of the vertical elastic vibration reduction mechanism is connected to the reactor, and the other end is connected to the guide rail. The vertical elastic vibration reduction mechanism includes an inclined rod, an elastic component, and a fixing component. When the reactor vibrates up and down in the vertical direction, the displacement of the inclined rod drives the elastic component to reciprocate along the length direction of the guide rail. The elastic component absorbs and releases the vibration force generated by the reactor in the vertical direction, thereby playing a role in vibration reduction. The sleeper supports the guide rail to ensure the stability and load-bearing capacity of the guide rail. One end of the horizontal friction vibration reduction mechanism is connected to the guide rail, and the other end is connected to the sleeper. The horizontal friction vibration reduction mechanism includes a steel plate layer and a friction damping layer. When the reactor vibrates reciprocally in the horizontal direction, it drives the guide rail to vibrate, and then relative movement is generated between the steel plate layer and the friction damping layer to form friction damping, absorbing the vibration force generated by the reactor in the horizontal direction. In summary, through the synergistic effect of the vertical elastic vibration reduction mechanism and the horizontal friction vibration reduction mechanism, this shock and vibration dual-control device effectively absorbs the vibration forces of the reactor in the vertical and horizontal directions, improves the stability and safety of the reactor, and ensures that the reactor can still be used normally during an earthquake.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. The terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0030] In the description of the present invention, it should be understood that the terms "first" and "second" in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.

[0031] As Figures 1 to 5As shown in the figure, an embodiment of the present invention preferably provides a vibration and shock dual-control device for a reactor, which includes a guide rail 3, a vertical elastic vibration damping mechanism 2, a sleeper 5, and a horizontal friction vibration damping mechanism 4. The guide rail 3 is arranged below the reactor 1 to assist the reactor 1 in vibration damping; one end of the vertical elastic vibration damping mechanism 2 is connected to the reactor 1, and the other end is connected to the guide rail 3. The vertical elastic vibration damping mechanism 2 includes an inclined rod 21, an elastic component 22, and a fixing component 23. The fixing component 23 is arranged on the guide rail 3. The number of elastic components 22 is at least two, and the elastic components 22 are respectively arranged at both ends of the fixing component 23. The elastic component 22 is connected to the inclined rod 21, and the end of the inclined rod 21 away from the elastic component 22 is connected to the reactor 1. When the reactor 1 moves vertically, the ends of the inclined rod 21 close to the elastic component 22 are driven to approach or move away from each other, thereby driving the elastic component 22 to reciprocate along the length direction of the guide rail 3. The elastic component 22 is used to absorb and release the vibration force generated by the reactor 1; the sleeper 5 is horizontally arranged below the guide rail 3 to support the guide rail 3; one end of the horizontal friction vibration damping mechanism 4 is connected to the guide rail 3, and the other end is connected to the sleeper 5. The horizontal friction vibration damping mechanism includes a steel plate layer 41 and a friction damping layer 42. One end of the steel plate layer 41 is connected to the guide rail 3, and the other end is connected to the friction damping layer 42. When the vibration of the reactor 1 drives the vibration of the guide rail 3, relative movement is generated between the steel plate layer 41 and the friction damping layer 42, thereby forming friction damping to absorb the vibration force generated by the reactor 1.

[0032] Based on the above technical features, in the present invention, the guide rail 3 is arranged below the reactor 1, and the guide rail 3 assists the reactor 1 in vibration damping, providing an installation foundation for the vertical elastic vibration damping mechanism 2 and the horizontal friction vibration damping mechanism 4; the vertical elastic vibration damping mechanism 2 is arranged, one end of the vertical elastic vibration damping mechanism 2 is connected to the reactor 1, and the other end is connected to the guide rail 3. The vertical elastic vibration damping mechanism 2 includes an inclined rod 21, an elastic component 22, and a fixing component 23. When the reactor 1 vibrates vertically up and down, the displacement of the inclined rod 21 drives the elastic component 22 to reciprocate along the length direction of the guide rail 3. The elastic component 22 absorbs and releases the vibration force generated by the reactor 1 in the vertical direction, thereby playing a role in vibration damping; the sleeper 5 is arranged, and the sleeper 5 supports the guide rail 3 to ensure the stability and bearing capacity of the guide rail 3; the horizontal friction vibration damping mechanism 4 is arranged, one end of the horizontal friction vibration damping mechanism 4 is connected to the guide rail 3, and the other end is connected to the sleeper 5. The horizontal friction vibration damping mechanism 4 includes a steel plate layer 41 and a friction damping layer 42. When the reactor 1 vibrates horizontally in a reciprocating manner, it drives the vibration of the guide rail 3, and then relative movement is generated between the steel plate layer 41 and the friction damping layer 42, forming friction damping to absorb the vibration force generated by the reactor 1 in the horizontal direction. In summary, through the synergistic effect of the vertical elastic vibration damping mechanism 2 and the horizontal friction vibration damping mechanism 4, this vibration and shock dual-control device effectively absorbs the vibration force of the reactor 1 in the vertical and horizontal directions, improves the stability and safety of the reactor 1, and ensures that the reactor 1 can still be used normally during an earthquake.

[0033] In some embodiments of the present invention, as Figure 2 shown, the elastic component 22 includes a sliding member 221 and a spring member 222. One end of the spring member 222 facing away from the fixed component 23 is connected to the sliding member 221. The sliding member 221 is disposed on the guide rail 3, and the sliding member 221 reciprocates along the length direction of the guide rail 3 on the guide rail 3. One end of the sliding member 221 facing away from the guide rail 3 is connected to the inclined rod 21. When the sliding member 221 reciprocates along the length direction of the guide rail 3 on the guide rail 3, the spring member 222 is used to absorb and release the force generated by the reciprocating movement of the sliding member 221. Through the reciprocating movement of the sliding member 221 on the guide rail 3 and the absorption and release actions of the spring member 222, the elastic component 22 can efficiently absorb the vibration force generated by the reactor 1, which helps to reduce the impact of the vibration of the reactor 1 on the surrounding environment and equipment, improve the stability and safety of the overall system. The design of the spring member 222 enables the elastic component 22 to adapt to vibrations of different frequencies and amplitudes. Whether it is a slight vibration with a small amplitude or a strong vibration with a large amplitude, the spring member 222 can absorb and release energy through its elastic deformation, so as to maintain the stable operation of the reactor 1. The elastic component 22 is composed of a sliding member 221 and a spring member 222, with a simple and clear structure, easy to install and maintain. When replacement or maintenance is required, it can be conveniently disassembled and replaced, reducing the maintenance cost and difficulty. By reducing the impact of the vibration of the reactor 1 on the surrounding environment and equipment, the elastic component 22 helps to reduce the wear and fatigue of the equipment, which helps to improve the service life and reliability of the equipment, and reduce the failure rate and maintenance cost caused by vibration.

[0034] In some embodiments of the present invention, as Figure 5 shown, the sliding member 221 includes a slider 2211 and steel balls 2212. The slider 2211 is disposed above the guide rail 3, and a groove recessed in the direction away from the guide rail 3 is provided between the slider 2211 and the guide rail 3. The steel balls 2212 are disposed in the groove, and the steel balls 2212 are in rolling connection with the guide rail 3 in the groove. The steel balls 2212 are used to convert the sliding friction between the slider 2211 and the guide rail 3 into rolling friction. The steel balls 2212 convert the sliding friction between the slider 2211 and the guide rail 3 into rolling friction. The rolling friction is much smaller than the sliding friction. Therefore, this design significantly reduces the resistance when the slider 2211 moves on the guide rail 3, making the sliding smoother. Due to the reduction of the rolling friction, the movement of the slider 2211 on the guide rail 3 is more accurate and stable. This helps to improve the movement accuracy and positioning accuracy of the entire system. The sliding friction easily causes wear of the guide rail 3 and the slider 2211, while the rolling friction significantly reduces this wear. Therefore, this design extends the service life of the guide rail 3 and the slider 2211 and reduces the maintenance cost.

[0035] As some embodiments of the present invention, such as Figure 5 As shown, the number of steel balls 2212 is multiple, and the multiple steel balls 2212 are arranged at intervals along the length direction of the groove, and a lubricating layer is provided on the outside of each steel ball 2212. The multiple steel balls 2212 are arranged at intervals along the length direction of the groove, so that the number of contact points between the slider 2211 and the guide rail 3 increases, and the contact area increases. Since each steel ball 2212 plays a role in rolling friction, the friction force between the slider 2211 and the guide rail 3 is further reduced as a whole. The existence of the lubricating layer further reduces the friction coefficient between the steel ball 2212 and the guide rail 3, making the rolling smoother and the friction force further reduced. The interval arrangement of the multiple steel balls 2212 makes the movement of the slider 2211 on the guide rail 3 more stable. Since each steel ball 2212 can roll independently, even if a certain steel ball 2212 is subjected to a small unbalanced force, it will not have a significant impact on the movement stability of the entire system. The multiple steel balls 2212 jointly share the load borne by the slider 2211, enhancing the load-bearing capacity of the entire slider 221, which is particularly important for application scenarios that require bearing large loads.

[0036] As some embodiments of the present invention, such as Figure 4 As shown, the fixing component 23 includes a first fixing block 231 and a second fixing block 232. The first fixing block 231 is respectively arranged at both ends of the guide rail 3. The first fixing block 231 is located above the sleeper 5, and the first fixing block 231 is fixedly connected to the sleeper 5 through fasteners. The second fixing block 232 is arranged above the guide rail 3. The second fixing block 232 wraps the guide rail 3, and both ends of the second fixing block 232 are respectively connected to the first fixing block 231. The combined design of the first fixing block 231 and the second fixing block 232 provides a solid support for the guide rail 3, effectively preventing the guide rail 3 from being displaced or loosened during use and enhancing the stability of the entire system. At the same time, the first fixing block 231 is fixedly connected to the sleeper 5 through fasteners, ensuring the tight connection between the guide rail 3 and the sleeper 5, improving the connection strength, and enabling the guide rail 3 to withstand greater loads and vibrations. The design of the second fixing block 232 wrapping the guide rail 3 provides comprehensive protection for the guide rail 3, preventing the guide rail 3 from being damaged by external factors and extending the service life of the guide rail 3.

[0037] As some embodiments of the present invention, such as Figure 3As shown in the figure, the steel plate layer 41 includes an upper steel plate 411, a main steel plate 412, and a lower steel plate 413 that are sequentially arranged at intervals from top to bottom in the vertical direction. The upper steel plate 411 is connected to the guide rail 3 through fasteners. The main steel plate 412 is connected to the sleeper 5 by inserting steel sheets on the plate body into the sleeper 5. The lower steel plate 413 is connected to the ground through steel spines on the plate body. The connection of the upper steel plate 411 to the guide rail 3 through fasteners ensures the stable connection between the guide rail 3 and the steel plate layer 41, preventing the shaking or displacement of the guide rail 3. The main steel plate 412 forms a tight bond with the sleeper 5 by inserting steel sheets on the plate body into the sleeper 5, enhancing the connection strength between the sleeper 5 and the steel plate layer 41. The lower steel plate 413 provides an additional ground anchor effect by inserting steel spines on the plate body into the ground, making the entire steel plate layer 41 more firmly fixed to the ground and enhancing the seismic resistance of the entire structure. The design of the three-layer steel plate enables the steel plate layer 41 to bear a greater load. The upper steel plate 411 directly supports the guide rail 3 and the slider 221. The main steel plate 412 serves as an intermediate support layer to disperse the load. The lower steel plate 413 transfers the load to the ground through its connection with the ground, forming a stable load-bearing system.

[0038] As some embodiments of the present invention, as Figure 3 shown in the figure, the friction damping layer 42 includes a first friction plate 421. One end of the first friction plate 421 is connected to the upper steel plate 411, and the other end is connected to the main steel plate 412. The first friction plate 421 is used to limit the displacement of the upper steel plate 411 and the main steel plate 412 in the horizontal direction. The main function of the first friction plate 421 is to limit the displacement of the upper steel plate 411 and the main steel plate 412 in the horizontal direction. When subjected to external forces, such as lateral forces of wind and seismic forces, the first friction plate 421 effectively resists these forces through its frictional action, maintaining the relative position stability of the upper steel plate 411 and the main steel plate 412. By connecting the first friction plate 421 between the upper steel plate 411 and the main steel plate 412, the connectivity between these two steel plate layers 41 is enhanced, making the entire steel plate layer 41 structure more compact and integral. When the first friction plate 421 is subjected to external forces, it will generate a certain frictional damping and consume part of the energy. This damping effect helps to reduce the vibration amplitude of the structure under dynamic action and improve the dynamic stability of the structure.

[0039] As some embodiments of the present invention, as Figure 3As shown, the friction damping layer 42 further includes a second friction plate 422. The second friction plate 422 is arranged at an interval from the first friction plate 421 in the vertical direction. One end of the second friction plate 422 is connected to the main body steel plate 412, and the other end is connected to the lower steel plate 413. The second friction plate 422 is used to limit the displacement of the main body steel plate 412 and the lower steel plate 413 in the horizontal direction. The addition of the second friction plate 422 and the first friction plate 421 together form a double-layer displacement limiting mechanism. The first friction plate 421 limits the displacement of the upper steel plate 411 and the main body steel plate 412 in the horizontal direction, while the second friction plate 422 limits the displacement of the main body steel plate 412 and the lower steel plate 413 in the horizontal direction. This double-layer design enhances the overall stability of the structure, effectively preventing the relative sliding between the steel plate layers 41. The frictional force between the second friction plate 422 and the main body steel plate 412 and the lower steel plate 413 provides an additional damping effect for the structure. When the structure is subjected to an external force, the second friction plate 422 will consume part of the energy, reduce the vibration amplitude of the structure, and improve the dynamic stability of the structure.

[0040] As some embodiments of the present invention, as Figure 1 shown, the number of the guide rails 3 is at least two. The two guide rails 3 are arranged at an interval in the horizontal direction, and each guide rail 3 is arranged vertically. The number of the sleepers 5 is at least three. The three sleepers 5 are arranged horizontally below the guide rails 3 in the horizontal direction. The interval arrangement of the two or more guide rails 3 forms a broader support base, effectively enhancing the stability of the entire structure. This design can better resist external forces in the horizontal direction and ensure the stability of the structure. The combined design of the multiple guide rails 3 and the sleepers 5 enables the entire system to bear a greater load. As the main load-bearing components, the increase in the number of the guide rails 3 means that more forces can be dispersed, while the sleepers 5 provide a solid support to ensure the effective transmission of the load. The horizontal arrangement of the three or more sleepers 5 helps to optimize the mechanical distribution and reduce the phenomenon of local stress concentration. This design makes the load more evenly distributed between the sleepers 5, reduces the stress on a single sleeper 5, and extends its service life.

[0041] As some embodiments of the present invention, as Figure 1As shown in the figure, the number of vertical elastic vibration damping mechanisms 2 and horizontal friction vibration damping mechanisms 4 is multiple. The multiple vertical elastic vibration damping mechanisms 2 and horizontal friction vibration damping mechanisms 4 are respectively arranged at the four corners of the reactor 1. The simultaneous arrangement of the vertical elastic vibration damping mechanism 2 and the horizontal friction vibration damping mechanism 4 at the four corners of the reactor 1 realizes the full-range vibration damping of the reactor 1 in the vertical and horizontal directions. The vertical elastic vibration damping mechanism 2 can effectively absorb and relieve vertical vibrations, such as vibrations caused by the vibration of the equipment itself or external impacts; while the horizontal friction vibration damping mechanism 4 can limit and consume the vibration energy in the horizontal direction, such as the horizontal shaking caused by an earthquake. The layout of the vibration damping mechanisms at the four corners provides uniform support and stable restraint for the reactor 1. This layout method can ensure that the reactor 1 can maintain a stable posture when subjected to external forces, and avoid safety accidents such as tilting or overturning. The combined use of multiple vibration damping mechanisms can work together synergistically to improve the overall vibration damping effect. The vertical elastic vibration damping mechanism 2 and the horizontal friction vibration damping mechanism 4 complement each other in the vibration damping mechanism and act together on the reactor 1, enabling it to maintain good vibration control performance under various working conditions. The layout of the vibration damping mechanisms at the four corners helps to evenly distribute the stress on the reactor 1. This layout method can avoid stress concentration phenomena, reduce the stress on local areas, and extend the service life of the reactor 1 and the vibration damping mechanisms.

[0042] In summary, compared with the prior art, the shock and vibration double-control device for a reactor provided by the embodiment of the present invention has the following beneficial effects: The guide rail 3 is arranged below the reactor 1. The guide rail 3 assists the reactor 1 in vibration damping and provides an installation basis for the vertical elastic vibration damping mechanism 2 and the horizontal friction vibration damping mechanism 4. One end of the vertical elastic vibration damping mechanism 2 is connected to the reactor 1, and the other end is connected to the guide rail 3. The vertical elastic vibration damping mechanism 2 includes an inclined rod 21, an elastic component 22, and a fixing component 23. When the reactor 1 vibrates up and down in the vertical direction, the displacement of the inclined rod 21 drives the elastic component 22 to reciprocate along the length direction of the guide rail 3. The elastic component 22 absorbs and releases the vibration force generated by the reactor 1 in the vertical direction, thereby playing a role in vibration damping. The sleeper 5 supports the guide rail 3 to ensure the stability and load-bearing capacity of the guide rail 3. One end of the horizontal friction vibration damping mechanism 4 is connected to the guide rail 3, and the other end is connected to the sleeper 5. The horizontal friction vibration damping mechanism 4 includes a steel plate layer 41 and a friction damping layer 42. When the reactor 1 vibrates reciprocally in the horizontal direction, it drives the guide rail 3 to vibrate, and then relative movement is generated between the steel plate layer 41 and the friction damping layer 42, forming friction damping to absorb the vibration force generated by the reactor 1 in the horizontal direction. In summary, through the synergistic action of the vertical elastic vibration damping mechanism 2 and the horizontal friction vibration damping mechanism 4, this shock and vibration double-control device effectively absorbs the vibration forces of the reactor 1 in the vertical and horizontal directions, improves the stability and safety of the reactor 1, and ensures that the reactor 1 can still be used normally during an earthquake.

[0043] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
