Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for PLC control cabinets, specifically a cabinet shock absorber for PLC control cabinets. Background Technology

[0002] PLC control cabinets are widely used in industrial production and automation control. They typically integrate a large number of precision electronic components and control modules, which are highly sensitive to vibration. In actual use, PLC control cabinets may be subjected to various external vibrations and shocks, such as mechanical vibrations during equipment operation, bumps during transportation, and resonance from other equipment in the workshop. Long-term vibration can not only affect the normal operating stability of the internal components of the control cabinet, but may also lead to problems such as loose components and solder joint detachment. In severe cases, it can even cause the entire control system to malfunction, affecting production progress and equipment safety.

[0003] However, existing PLC control cabinet vibration dampers still have some drawbacks in practical use: although some dampers have a certain damping capacity, they neglect the heat dissipation problem of the control cabinet during the damping process. Since the internal components of the PLC control cabinet generate a lot of heat when the PLC control cabinet is working, the tight fit between the damping structure and the cabinet may hinder the flow of heat dissipation air, causing the internal temperature of the cabinet to rise, affecting the service life and working performance of the components.

[0004] To address these issues, we designed a PLC control cabinet vibration damper. Utility Model Content

[0005] The purpose of this utility model is to provide a cabinet vibration damper for PLC control cabinets to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a cabinet vibration damper for a PLC control cabinet, including a PLC control cabinet body. A base plate is fixedly installed on one side of the PLC control cabinet body. A vibration damping box is sleeved on the side of the base plate away from the PLC control cabinet body. Multiple vibration damping balls are placed inside the vibration damping box to fill it. Limiting plates are fixedly connected to both sides of the base plate inside the vibration damping box. Multiple flow channels are arranged through the base plate, and the multiple flow channels are distributed in a matrix on the base plate. Damping strips are longitudinally embedded in the inner wall of the flow channels. A wave guide grid is provided inside the vibration damping box. The crest of the wave guide grid faces the opening of the flow channel, and a gap is reserved between the crest of the wave guide grid and the base plate.

[0007] Furthermore, the gap is filled with a layer of thermally conductive silicone grease.

[0008] Furthermore, the wave guide grid has turbulence protrusions at the crests, and the turbulence protrusions are distributed at equal intervals.

[0009] Furthermore, two symmetrical suction cups are fixedly installed on the side of the shock-absorbing box away from the base plate.

[0010] Furthermore, the top and bottom of the shock absorber box are fixedly installed with reinforcing plates, and two nuts are provided inside each of the two reinforcing plates, with bolts threaded into the interior of each nut.

[0011] Furthermore, the wave guide grid includes longitudinal ribs and transverse ribs, which are orthogonally arranged, and multiple longitudinal ribs and transverse ribs are fixedly installed on the inner wall of the shock absorber box at equal intervals.

[0012] Furthermore, the cross-section of the flow channel is a regular hexagon, and the cross-section of the damping strip is T-shaped.

[0013] Furthermore, the T-shaped head of the damping strip protrudes from the sidewall plane of the flow channel, and the damping strip is made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the combined design of the flow channel and the wave guide grid not only achieves good heat dissipation, but also plays an important role in the vibration reduction process. The hot air inside the PLC control cabinet is discharged through the flow channel. The airflow impacts the crest of the wave guide grid to generate a vortex separation effect, which enhances turbulent heat transfer. The negative pressure zone formed by the wave trough can draw in external cold air to replenish it, improving the passive convection efficiency and effectively solving the problem of the vibration reduction structure affecting heat dissipation. When subjected to lateral impact, the wave trough of the wave guide grid is compressed and elastically deformed, which pushes the damping strip in the flow channel to undergo shear displacement. The friction between the damping strip and the side wall of the flow channel generates heat, further consuming the impact energy, thus achieving the synergistic effect of vibration reduction and heat dissipation.

[0016] 2. In this utility model, by setting multiple shock-absorbing balls inside the shock-absorbing box, when the PLC control cabinet body is impacted, the shock-absorbing balls can first buffer the shaking caused by the impact, initially consume vibration energy, and play the first layer of shock absorption role. At the same time, the limiting plates on both sides of the base plate can limit the excessive displacement of the base plate in the shock-absorbing box, ensuring the stability of the shock absorption structure.

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a PLC control cabinet damper, including a PLC control cabinet body 1, a base plate 2 fixedly installed on one side of the PLC control cabinet body 1, a damping box 3 sleeved on the side of the base plate 2 away from the PLC control cabinet body 1, a plurality of damping balls filling the damping box 3 are placed inside the damping box 3, limit plates 4 are fixedly connected to both sides of the base plate 2 inside the damping box 3, a plurality of flow channels 5 are provided through the base plate 2, the plurality of flow channels 5 are distributed in a matrix on the base plate 2, damping strips 6 are longitudinally embedded in the inner wall of the flow channels 5, a wave guide grid 7 is provided on the inner side of the damping box 3, the wave crest of the wave guide grid 7 faces the opening of the flow channel 5, and a gap is reserved between the wave crest of the wave guide grid 7 and the base plate 2.

[0025] In practical implementation, when using the PLC control cabinet vibration damper, first place the PLC control cabinet body 1 on one side of the wall, so that the side of the vibration damping box 3 away from the base plate 2 faces the wall. Then, press the PLC control cabinet body 1 against the wall, so that the two suction cups 8 on the vibration damping box 3 are attached to the wall, completing the initial fixation. After the attachment is completed, use a screwdriver to screw the bolts 10 on the reinforcing plate 9 into the wall. Through the threaded connection between the bolts 10 and the wall, the vibration damping box 3 is completely fixed to prevent it from shifting during subsequent use.

[0026] When the PLC control cabinet body 1 is subjected to collision or vibration, firstly, the shock-absorbing balls in the shock-absorbing box 3 will buffer the shaking caused by the collision and absorb some of the vibration energy, thus playing a preliminary shock-absorbing role. The limiting plates 4 on both sides of the base plate 2 can limit the range of movement of the base plate 2 in the shock-absorbing box 3, so as to avoid excessive displacement of the base plate 2 and affect the shock absorption effect.

[0027] During the operation of the PLC control cabinet body 1, hot air is generated inside. The hot air is discharged through multiple flow channels 5 on the base plate 2. Since the cross-section of the flow channel 5 is a regular hexagon, the matrix distribution of the flow channels 5 forms a honeycomb structure, which not only ensures the rigidity of the structure but also reduces the overall weight. When the airflow flows in the flow channel 5, it will contact the damping strips 6 on the inner wall. The T-shaped head of the damping strip 6 protrudes from the side wall plane of the flow channel 5, which can play a certain role in disturbing the airflow. When the airflow flows out of the flow channel 5, it will hit the crest of the wave guide grid 7. The wave guide grid 7 is orthogonally arranged by longitudinal ribs 11 and transverse ribs 12. The turbulent protrusions at the top of its crests further aggravate the disturbance of the airflow, generate a vortex separation effect, and enhance turbulent heat transfer. At the same time, the trough of the wave guide grid 7 forms a negative pressure zone, which can draw in external cold air for replenishment, effectively improving the heat dissipation efficiency of passive convection.

[0028] The gap between the wave crest of the wave guide grid 7 and the substrate 2 is filled with a thermally conductive silicone grease layer. The thermally conductive silicone grease layer can quickly conduct the heat absorbed on the wave guide grid 7 to the outer shell of the shock absorber box 3, and then dissipate it into the external environment. This avoids the problem of the shock absorber box 3 being in close contact with the PLC control cabinet body 1 and obstructing the heat dissipation airflow, thus ensuring the heat dissipation performance of the PLC control cabinet body 1.

[0029] When the PLC control cabinet body 1 is subjected to a lateral impact, the PLC control cabinet body 1 will drive the base plate 2 to move into the shock absorption box 3. The base plate 2 will squeeze the wave guide grid 7. The trough of the wave guide grid 7 will undergo elastic deformation under pressure. During the deformation process, it will push the damping strip 6 in the flow channel 5 to undergo shear displacement. Since the damping strip 6 is made of rubber and its T-shaped structure is anchored to the inner wall of the flow channel 5, friction will be generated between the damping strip 6 and the side wall of the flow channel 5. The friction generates heat and consumes the impact energy. When the impact is eliminated, the wave guide grid 7 will deform and recover under its own elasticity, driving the damping strip 6 to elastically reset, waiting for the buffer of the next impact.

[0030] See Figure 2 Two symmetrical suction cups 8 are fixedly installed on the side of the shock absorber box 3 away from the base plate 2. In the initial stage of installation, the shock absorber box 3 can be quickly fixed to the wall, which facilitates the subsequent installation of bolts 10 and ensures the stability of the installation process.

[0031] See Figure 2The top and bottom of the shock absorber box 3 are fixedly installed with reinforcing plates 9. The nuts inside the reinforcing plates 9 cooperate with the bolts 10. By screwing the bolts 10 into the wall, the shock absorber box 3 can be firmly fixed to the wall, which further enhances the overall installation stability of the shock absorber. Even in a strong vibration environment, it can be ensured that the shock absorber will not loosen or shift.

[0032] See Figure 3 The longitudinal ribs 11 and transverse ribs 12 of the wave guide grid 7 are orthogonally arranged and fixed at equal intervals on the inner wall of the shock absorber box 3. This structural design enables the wave guide grid 7 to have good load-bearing capacity and elastic deformation capacity, and can evenly disperse the force when subjected to impact, thereby improving the reliability of shock absorption.

[0033] See Figure 5 The hexagonal cross-section design of the flow channel 5 makes the airflow smoother, while the honeycomb structure design enhances the overall strength of the substrate 2. The T-shaped cross-section structure of the damping strip 6, with its head protruding from the side wall plane of the flow channel 5, can effectively prevent the damping strip 6 from falling off the inner wall of the flow channel 5 when subjected to shear force, thus ensuring the long-term effective use of the damping strip 6.

[0034] Working principle:

[0035] When using the PLC control cabinet body 1, first place the PLC control cabinet body 1 on one side of the wall, then press the PLC control cabinet body 1 against the wall so that the suction cup 8 is attached to the wall. After attachment, use a screwdriver to screw the bolt 10 into the wall to completely fix the shock absorption box 3. At this time, when the PLC control cabinet body 1 is hit, the shock absorption ball inside the shock absorption box 3 will buffer the shaking caused by the impact, thereby achieving the purpose of protecting the PLC control cabinet body 1.

[0036] Hot air inside the PLC control cabinet body 1 is discharged through the circulation channel 5. The airflow impacts the crest of the wave guide grid 7, generating a vortex separation effect, which enhances turbulent heat transfer. The trough forms a negative pressure zone, drawing in external cold air to replenish it, improving passive convection efficiency. Thermal grease quickly conducts the heat from the wave guide grid 7 to the outer shell of the shock absorber box 3 for heat dissipation, preventing the shock absorber box 3 from being in close contact with the PLC control cabinet body 1 and obstructing the heat dissipation airflow.

[0037] When subjected to a lateral impact, the PLC control cabinet body 1 drives the base plate 2 to squeeze the wave guide grid 7. The wave trough of the wave guide grid 7 is compressed and deformed elastically, which pushes the damping strip 6 in the flow channel 5 to undergo shear displacement. The damping strip 6 and the side wall of the flow channel 5 rub against each other to generate heat and consume the impact energy. After the impact is eliminated, the deformation of the wave guide grid 7 is restored and the damping strip 6 is elastically reset.

[0038] The flow channel 5 provides an airflow channel. The honeycomb structure combines high specific stiffness and lightweight. Strip-shaped damping strips 6 are longitudinally embedded in the inner wall of the flow channel 5. The damping strips 6 have a T-shaped anchoring structure in cross section and the top protrudes from the side wall plane of the flow channel 5. During lateral impact, the damping strips 6 undergo shear deformation to dissipate energy. The T-shaped structure prevents them from falling off. The inner side of the shock absorption box 3 is provided with a continuous wave guide grid 7. The wave crest faces the opening of the flow channel 5, which converts the straight airflow into turbulence and improves heat dissipation efficiency. The wave configuration provides elastic deformation space to buffer the impact. A gap is reserved between the wave guide grid 7 and the substrate 2. The gap is filled with graphene thermal conductive silicone grease, which allows for thermal expansion and contraction deformation. The silicone grease enhances heat conduction and does not hinder relative sliding.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
