Vibration isolators are typically installed between the rotating machinery and the foundation to attenuate the transmission of the mechanical equipment vibration energy onto the deck of the vessel. The conventional vibration isolator mainly uses a passive rubber vibration isolator, and the principle of the vibration isolator is that vibration energy is converted into heat energy through rubber deformation, partial vibration energy is absorbed, and the transmission of vibration to the downstream is reduced.
Although rubber vibration isolators are widely used, the rubber material has the problem of high temperature and easy aging, and meanwhile, the performance of the rubber is sensitive to the temperature, and the requirement on the temperature uniformity of the rubber at each position in the vibration isolator is high. The existing rubber vibration isolator has two reasons of overhigh temperature, one is that the rubber vibration isolator is continuously used for a long time to cause continuous heat accumulation, and the second is that the vibration load is far higher than normal operation in the starting and stopping process of equipment, so that the heat can be locally and rapidly accumulated. Because the rubber has poor heat conductivity, if the heat cannot be dissipated in time, the heat in the vibration isolator can be accumulated, so that the temperature of the vibration isolator is too high, the performance is reduced, and even the failure problem occurs. In addition, under partial operation conditions, due to the problem of mounting of the vibration isolator or abnormal operation of equipment, the phenomenon that local stress of the vibration isolator is too large, so that the local temperature is far higher than that of other positions can occur. In order to ensure that the vibration isolator has good operating temperature when being started, stopped and continuously operated, the vibration isolation effect and the service life of the vibration isolator are improved, and how to effectively dissipate heat of the rubber vibration isolator is an important problem.

At least one piezoelectric body 6 is further embedded in the rubber vibration isolation body 1, and the electric energy output end of the piezoelectric body 6 is electrically connected to the power supply end of the electric refrigeration piece 4 through a rectifier element.
Specifically, the rubber vibration isolation body 1 is a solid rubber body, and in this embodiment, a commonly used oblate rubber body is taken as an example for explanation, and the specific shape of the rubber body can be reasonably selected according to the use requirement, and is not limited here. The upper mounting plate 2 is used for rigid connection with a pump, a motor and other vibration equipment, and the lower mounting plate 3 is used for mounting the rubber vibration isolation device on a fixed base or a deck, and more particularly can be detachably connected through a mounting bolt 9.
The electric refrigerating sheet 4 can be a semiconductor refrigerating sheet, the principle of the electric refrigerating sheet is an inverse Seebeck effect, namely when an N-type element and a P-type element are connected into a galvanic couple pair, after direct current is switched on in the circuit, energy transfer can be generated, and the current flows to a joint of the P-type element from the N-type element to absorb heat to form a cold end; the junction from the P-type element to the N-type element releases heat to become the hot end. In this embodiment, the position in the rubber vibration isolation body where the electric cooling plate 4 is located is a cold end, and the hot end extends to the lower mounting plate 3 through a conductor element, and the conductor element may be a wire or a metal conductive member, such as a ductile metal plate 5. Keep invariable low temperature with the cold junction of electric refrigeration piece 4 through the electric energy, and with heat transfer to lower mounting panel 3 in the rubber vibration isolation body 1, and then in time derive the external environment.
The piezoelectric body 6 may be made of a piezoelectric material, such as a piezoelectric ceramic sheet, a piezoelectric crystal, an organic piezoelectric material, or a composite piezoelectric material, and the piezoelectric body 6 is mainly used as the piezoelectric ceramic sheet in this embodiment for illustration. When driven by the vibration of mechanical equipment, the rubber vibration isolation body 1 deforms, and the piezoelectric body 6 deforms accordingly, so that the vibration mechanical energy is converted into electric energy. Along with the periodic vibration of mechanical equipment, the rubber vibration isolation body 1 is pressed down and pulled up periodically or swings left and right, the piezoelectric body 6 converts the periodic mechanical vibration into continuous alternating current, and then the alternating current is converted into direct current which can be supplied to the electric refrigerating sheet 4 through a rectifying element (such as a rectifier) so as to continuously generate cold at the cold end of the electric refrigerating sheet 4 (namely, inside the rubber vibration isolation body 1), and constant low temperature is generated to continuously cool the rubber vibration isolation body 1.

Meanwhile, a piezoelectric body 6 is embedded in the solid rubber vibration isolation body 1, the piezoelectric body 6 can convert the vibration energy of the rubber vibration isolation body 1 into electric energy, and the electric energy is used as the power supply energy of the electric refrigeration sheet 4. When the self-cooling rubber vibration isolation device begins to bear load, the piezoelectric body 6 begins to generate electric energy at the same time, and the electric energy is directly supplied to the electric refrigerating sheet 4 to begin to work; when the self-cooling rubber vibration isolation device is subjected to large load or high-frequency vibration, the electric energy generated by the piezoelectric body 6 is increased, the electric energy supplied to the electric refrigerating sheet 4 is increased, the refrigerating power is synchronously improved, and the cooling capacity is synchronously enhanced.

Further, as shown in fig. 1 and 2, the lower mounting plate 3 is further provided with a phase-change heat dissipation cavity 7, and the phase-change heat dissipation cavity 7 is filled with a phase-change material 71. The conductor element extends into the phase change heat dissipation chamber 7 and is in contact with the phase change material 71. Further, the melting point of the phase change material is 10 ℃ to 50 ℃. The phase change material may be a liquid metal. The phase-change heat dissipation cavity 7 is used as the hot end of the electric refrigerating sheet 4, before the starting process of vibration equipment such as a pump, a motor and the like, the self-cooling rubber vibration isolation device is in a non-working state, and the phase-change material 71 (such as liquid metal) in the phase-change heat dissipation cavity 7 is in a solid state; in the starting process of the vibration equipment, the running state is unstable, and the vibration equipment has extremely strong vibration load, so that heat in the rubber vibration isolation body 1 is rapidly gathered, the phase-change material 71 in the phase-change heat dissipation cavity 7 is melted, and the heat led out from the rubber vibration isolation body 1 can be rapidly absorbed and stored in a latent heat mode due to the fact that the phase-change material 71 is melted and needs to absorb a large amount of heat, so that the running requirement of short-time large load in the starting process is met.
When the vibration equipment continuously operates, the liquid metal can also play a role in guiding out heat in the rubber vibration isolation body 1, and the heat from the rubber vibration isolation body 1 is quickly transferred to the lower mounting plate 3 through the high heat conduction capacity of the liquid metal.
The phase change process of the phase change material 71 quickly absorbs the redundant heat generated by the vibration in the starting process of the equipment, so that the heat in the rubber vibration isolation body 1 is quickly gathered to the phase change heat dissipation cavity 7, the temperature balance of all the rubber in the rubber vibration isolation body 1 is maintained, the purpose of continuous heat dissipation in the rubber vibration isolation body 1 is met, and the starting working performance, the continuous working performance and the service life of the rubber vibration isolation device can be effectively improved.
Furthermore, as shown in fig. 1, the conductor element is a ductile metal sheet 5, the number of the electric cooling sheets 4 is plural, and the ductile metal sheets 5 corresponding to the electric cooling sheets 4 are arranged in a fan shape with the center of the lower mounting plate 3 as the center of a circle. Specifically, inside toughness sheetmetal 5 inlayed and located solid rubber vibration isolation body 1, can follow the deformation of rubber and take place the displacement, toughness sheetmetal 5 has certain toughness, can the atress take place deformation, and the while is at the external force disappearance after the reconversion. The ductile metal sheet 5 not only can play a role in transferring deformation and current, but also can guide heat in the rubber vibration isolation body 1 into the lower mounting plate 3 in time.
Further, as shown in fig. 1, the length of the ductile metallic sheets 5 decreases as the angle between the ductile metallic sheets 5 and the lower mounting plate 3 increases, i.e., the ductile metallic sheets 5 on both sides are longer, and the ductile metallic sheet 5 in the middle is shorter. In addition, the length of the ductile metallic sheet 5 is different according to different stretching angles, so as to match the configuration of different rubber vibration isolation devices. In the present embodiment, an oblate rubber vibration isolator is mainly used as an example for description.
Further, as shown in fig. 1, the length of the ductile metallic sheet 5 near the center line of the lower mounting plate 3 (i.e., the angle between the ductile metallic sheet 5 and the lower mounting plate 3 is close to 90 degrees) is less than 2/3 of the maximum compression amount of the rubber vibration isolating body 1 to prevent the ductile metallic sheet 5 from piercing the rubber vibration isolating body 1.
Further, as shown in fig. 1, each electric cooling plate 4 corresponds to one piezoelectric body 6, the piezoelectric body 6 is connected to one end of the ductile metal plate 5 close to the lower mounting plate 3, and the piezoelectric body 6 (e.g., piezoelectric ceramic plate) can maintain synchronous deformation with the ductile metal plate 5, that is, when the ductile metal plate 5 is displaced and changes its shape along with the vibration of the rubber vibration isolation body 1, the piezoelectric body 6 (e.g., piezoelectric ceramic plate) also generates corresponding displacement and change its shape. More specifically, the distance between two adjacent ductile metal sheets 5 is required to satisfy the deformation space requirement of the piezoelectric body 6.
Further, as shown in fig. 1, the length of the ductile metal sheet 5 is larger than that of the piezoelectric body 6. Because the ductile metal sheet 5 is longer and the piezoelectric body 6 is shorter, the pressure applied to the ductile metal sheet 5 can be amplified and then applied to the piezoelectric body 6 by combining the lever principle, so that the pressure of the piezoelectric body 6 is increased, and more electric energy is generated.
Further, a cooling fin 8 is arranged on one side of the lower mounting plate 3, which is far away from the rubber vibration isolation body 1. Through setting up multiunit fin 8, can release the heat that electric refrigeration piece 4 derived through fin 8, because rubber vibration isolation device still has some vibration energy can transmit to mounting panel 3 down, consequently, fin 8 also can follow down mounting panel 3 and produce the vibration of certain degree, in addition, marine environment generally is in during the stormy waves, there is certain periodicity jolt, can become the exothermic process of semi-compulsory convection with the natural convection heat release of fin 8 originally, the release rate of heat has been showing and has been promoted.
Fig. 3 to 5 are schematic diagrams showing deformation of the self-cooling rubber vibration isolating device in the present embodiment under external forces in different directions. The rubber vibration isolation device is subjected to periodic downward pressure and upward tension most frequently in the working process, fig. 3 shows the deformation of the rubber vibration isolation device under the action of downward pressure, and it can be seen that the rubber vibration isolation body 1 presents an obvious flattening trend under the downward acting force, and meanwhile, each ductile metal sheet 5 is driven to move downwards, and the angle between each ductile metal sheet 5 and the lower mounting plate 3 is reduced. Fig. 4 shows the deformation of the rubber vibration damping device in the presence of an upward tensile force, and the angle between the ductile metallic sheet 5 and the lower mounting plate 3 increases as the rubber vibration damping body 1 is stretched together with the ductile metallic sheet 5 in the presence of the upward tensile force. Under the action of periodic pressing and pulling, the piezoelectric body 6 (such as a piezoelectric ceramic sheet) will generate significant deformation, thereby generating electric energy to supply the working power source of the electric refrigerating sheet 4.
The self-cooling rubber vibration isolation device in this embodiment is not only suitable for vertical vibration, but also has certain adaptability to lateral acting force, and fig. 5 shows the deformation of the rubber vibration isolation device under the lateral acting force and the accompanying deformation of the ductile metal sheet 5 and the piezoelectric body 6, and it can be seen that, under the tangential acting force, the left piezoelectric body 6 (such as a piezoelectric ceramic sheet) deflects upwards, and the right piezoelectric body 6 (such as a piezoelectric ceramic sheet) deflects downwards, and at the same time, a part of the energy of the lateral acting force can be converted into electric energy.
According to the self-cooling rubber vibration isolation device provided by the invention, the electric refrigerating sheet 4 is embedded in the solid rubber vibration isolation body 1, and the heat absorbed by the electric refrigerating sheet 4 in the rubber vibration isolation body 1 is timely transferred to the lower mounting plate 3 by utilizing the conductive element, so that the heat is led out to the outside. Meanwhile, a piezoelectric body 6 is embedded in the solid rubber vibration isolation body 1, the piezoelectric body 6 can convert the vibration energy of the rubber vibration isolation body 1 into electric energy, and the electric energy is used as the power supply energy of the electric refrigeration sheet 4. When the self-cooling rubber vibration isolation device begins to bear load, the piezoelectric body 6 begins to generate electric energy at the same time, and the electric energy is directly supplied to the electric refrigerating sheet 4 to begin to work; when the self-cooling rubber vibration isolation device is subjected to large load or high-frequency vibration, the electric energy generated by the piezoelectric body 6 is increased, the electric energy supplied to the electric refrigerating sheet 4 is increased, the refrigerating power is synchronously improved, and the cooling capacity is synchronously enhanced.
