Description
Technical Field
[0001] The invention relates to the technical field of vibrators, and in particular to a vibrator which is beneficial to the heat dissipation of a variable frequency motor. Background Art
[0002] At present, the vibrator is the core equipment in the vibratory construction. It generates horizontal vibration force to vibrate the filler and the surrounding soil, thereby improving the bearing capacity of the foundation, reducing the amount of settlement, increasing the stability of the foundation, and improving the ability to resist earthquake liquefaction. The existing vibrator is generally composed of a shell, a variable frequency motor, an elastic coupling, a vibrator, a vibratory head, a water pipe, and a cable. The variable frequency motor has a shell, and the variable frequency motor is installed inside the shell. One end of the vibrator is connected to the output end of the variable frequency motor through a coupling, and the other end is connected to the vibratory head. The water pipe passes through the upper part of the vibrator and then passes through the middle position of the vibratory head.
[0003] The power of the vibrator depends on the power output value of the variable frequency motor. The greater the power of the motor, the greater the heat it generates during use. If the variable frequency motor generates severe heat, it may burn out. Therefore, it needs to be cooled down in time. However, the cooling effect of the variable frequency motor is not ideal, which is not conducive to the discharge of heat. Summary of the invention
[0004] The purpose of the present invention is to provide a vibrator that is beneficial to the heat dissipation of a variable frequency motor, which can effectively improve the heat dissipation effect of the variable frequency motor and avoid the risk of burning out due to excessive temperature when the variable frequency motor is working.
[0005] In order to solve the above technical problems, the present invention adopts the following solutions:
[0006] A vibrator that is beneficial to the heat dissipation of a variable frequency motor comprises a vibrator body, the vibrator body comprises an outer shell, a water pipe, a fixing plate for fixing the water pipe is provided on the outer side of the lower end of the outer shell, a variable frequency motor is provided inside the outer shell, an output shaft of the variable frequency motor is connected with an elastic coupling, the lower end of the elastic coupling is connected with a vibrator located inside the outer shell, a vibrating head is connected to the lower end of the vibrator, the water pipe penetrates from the upper part of the vibrator and then passes out from the middle part of the vibrating head, the variable frequency motor comprises a shell, a heat dissipation pipe is spirally wound on the shell, both ends of the heat dissipation pipe are respectively connected with the water pipe, and an elastic heat sink is provided between the shell and the outer shell.
[0007] In this solution, the shell serves as the main structure of the vibrator. The shell not only protects the internal components from the influence of the external environment, but also promotes the heat dissipation effect through its specific design. The water pipe is fixed by a fixing plate on the outer side of the lower end of the shell. The function of the water pipe is to guide the water flow to the front section of the vibrator to spray and form a high-pressure water flow to assist in hole making; the elastic coupling between the output shaft of the variable frequency motor and the vibrator ensures a flexible connection between the two, which can reduce the impact and noise caused by vibration, protect the motor and vibrator from damage, and improve the operating stability of the entire system; the vibrator is located inside the shell. The vibrator receives power from the variable frequency motor through an elastic coupling and converts it into vibration energy. The vibrator head connected to the lower end of the vibrator is the part that actually performs the vibration operation, and it transfers energy to the processed material or medium through vibration. The variable frequency motor will generate a lot of heat when working. In order to dissipate heat effectively, the design directly winds a spiral heat dissipation pipe on the housing of the variable frequency motor. The two ends of the heat dissipation pipe are connected to the water pipe respectively, forming a closed cooling water circulation system. When the cooling water enters the heat dissipation pipe through the water pipe, it can quickly absorb and take away the heat on the housing of the variable frequency motor, and then be discharged through the water pipe, thereby realizing efficient heat exchange. The elastic heat sink filled between the housing of the variable frequency motor and the outer shell not only plays a role in buffering and shock absorbing the variable frequency motor, but also further transfers the heat on the motor housing to the outer shell through its good thermal conductivity, thereby enhancing the overall heat dissipation effect.
[0008] This solution effectively solves the problem of high temperature generated during operation of the variable frequency motor by optimizing the heat dissipation system and adopting innovative measures such as elastic heat sinks. It not only improves the heat dissipation performance and service life of the variable frequency motor, but also enhances the operating stability and reliability of the entire vibrator. This design has broad application prospects in vibration equipment that requires efficient heat dissipation and stable operation.

[0027] Example 1
[0028] A vibrator that is beneficial to the heat dissipation of a variable frequency motor includes a vibrator body, the vibrator body includes an outer shell 1, a water pipe 5, a fixing plate 11 for fixing the water pipe 5 is provided on the outer side of the lower end of the outer shell 1, a variable frequency motor 2 is provided inside the outer shell 1, the output shaft of the variable frequency motor 2 is connected to an elastic coupling 6, the lower end of the elastic coupling 6 is connected to a vibrator 9 located inside the outer shell 1, the lower end of the vibrator 9 is connected to a vibrating head 10, the water pipe 5 is inserted from the upper part of the vibrator and then passes out from the middle part of the vibrating head 10, the variable frequency motor 2 includes a shell 201, a heat dissipation pipe 4 is spirally wound on the shell 201, both ends of the heat dissipation pipe 4 are respectively connected to the water pipe 5, and an elastic heat sink 3 is provided between the shell 201 and the outer shell 1.
[0029] In this embodiment, the variable frequency motor 2 itself is the prior art, and the vibrator is mainly composed of an axis and an eccentric block, and the structure is the prior art. The variable frequency motor 2 drives the axis to rotate and then drives the eccentric block to rotate, thereby generating vibration. The outer shell 1 serves as the main structure of the vibrator. The outer shell 1 not only protects the internal components from the influence of the external environment, but also promotes the heat dissipation effect through its specific design. The water pipe 5 is fixed by the fixing plate 11 on the outer side of the lower end of the outer shell 1. The function of the water pipe 5 is to guide the water flow to the front section of the vibrator to spray and form a high-pressure water flow to assist in hole making; the elastic coupling 6 between the output shaft of the variable frequency motor 2 and the vibrator 9 ensures a flexible connection between the two, which can reduce the impact and noise caused by vibration, protect the motor and vibrator 9 from damage, and improve the operating stability of the entire system; the vibrator 9 is located inside the outer shell 1. The vibrator 9 receives the power from the variable frequency motor 2 through the elastic coupling 6 and converts it into vibration energy. The vibrator head 10 connected to the lower end of the vibrator 9 is the part that actually performs the vibration operation, and it transfers energy to the processed material or medium through vibration. Figure 1 As shown, the variable frequency motor 2 generates a large amount of heat when working. In order to dissipate heat effectively, the design directly winds a spiral heat dissipation pipe 4 on the housing 201 of the variable frequency motor 2. The two ends of the heat dissipation pipe 4 are respectively connected to the water pipe 5 to form a closed cooling water circulation system. A flexible connecting pipe can be used at the connection between the heat dissipation pipe 4 and the water pipe 5. When the cooling water enters the heat dissipation pipe 4 through the water pipe 5, it can quickly absorb and take away the heat on the housing 201 of the variable frequency motor 2, and then be discharged through the water pipe 5, thereby realizing efficient heat exchange. The elastic heat dissipation body 3 filled between the housing 201 of the variable frequency motor 2 and the outer shell 1 not only has a buffering and shock-absorbing effect on the variable frequency motor 2, but also further transfers the heat on the motor housing 201 to the outer shell 1 through its good thermal conductivity, thereby enhancing the overall heat dissipation effect.
[0030] This solution effectively solves the problem of high temperature generated during operation of the variable frequency motor 2 by optimizing the heat dissipation system, adopting elastic heat dissipation body 3 and other innovative measures. It not only improves the heat dissipation performance and service life of the variable frequency motor 2, but also enhances the operating stability and reliability of the entire vibrator. This design has broad application prospects in vibration equipment that requires efficient heat dissipation and stable operation.
[0031] Furthermore, the housing 201 is provided with spiral grooves 2011 along its length direction. The grooves 2011 are adapted to the size of the heat dissipation pipe 4 , and the heat dissipation pipe 4 is embedded in the grooves 2011 .
[0032] Specifically, Figure 3As shown, after the heat pipe 4 is embedded in the groove 2011, the contact area with the shell 201 is greatly increased, thereby improving the heat conduction efficiency. The heat on the shell 201 can be transferred to the cooling water through the heat pipe 4 more quickly, achieving a more efficient heat exchange. The groove 2011 provides a stable support for the heat pipe 4, preventing the heat pipe 4 from loosening or shifting under vibration or impact. This stable connection method ensures the long-term stable operation of the heat dissipation system. The design of the spiral groove 2011 and the heat pipe 4 not only makes the entire heat dissipation system look neater and more beautiful, but also optimizes the structural layout and reduces unnecessary space occupation. This compact design is conducive to the miniaturization and lightweight of the entire vibrator. The close contact between the heat pipe 4 and the groove 2011 reduces the thermal resistance, allowing heat to be transferred more smoothly. This is of great significance for improving the heat dissipation efficiency of the variable frequency motor 2, reducing the operating temperature and extending the service life.
[0033] At the same time, the spiral groove 2011 is also set to make the heat dissipation tube 4 spiral. The spiral heat dissipation tube 4 forms a structure similar to a spring, and the heat dissipation tube 4 and the shell 201 are embedded. The spiral heat dissipation tube 4 can isolate the vibration generated by the vibrating punch 10 in the vertical direction, and reduce the impact of the vibration on the variable frequency motor 2. The heat dissipation tube 4 can be made of metal with good ductility, so that the buffering effect is better. The wall thickness of the heat dissipation tube 4 can be appropriately thickened to avoid breakage during the buffering process.
[0034] Furthermore, a heat-conducting adhesive for fixing the heat-dissipating pipe 4 is provided between the heat-dissipating pipe 4 and the inner wall of the groove 2011 .
[0035] Specifically, the heat-conducting adhesive can be used as an adhesive to firmly fix the heat pipe 4 on the inner wall of the groove 2011 to prevent it from loosening or shifting due to vibration changes during operation. This stable connection method ensures the stability and reliability of the heat dissipation system and ensures that heat can be continuously and efficiently transferred. The heat-conducting adhesive not only has excellent bonding performance, but also has good thermal conductivity. It can effectively fill the small gap between the heat pipe 4 and the inner wall of the groove 2011, reduce thermal resistance, and enable heat to be more smoothly transferred from the housing 201 to the heat pipe 4, and then taken away by cooling water. This design further improves the heat dissipation efficiency, helps to reduce the operating temperature of the variable frequency motor 2, and prolongs its service life. The heat-conducting adhesive also has certain insulation performance and shock absorption effect. In electrical equipment, insulation performance is crucial, which can prevent safety hazards such as current leakage and short circuit. At the same time, the shock absorption effect can reduce the mechanical stress caused by vibration and protect the heat pipe 4 and the variable frequency motor 2 from damage. In the subsequent maintenance and replacement work, the easy removal of the heat-conducting adhesive also provides convenience, so that the maintenance personnel can easily disassemble and replace the heat pipe 4.
[0036] Example 2
[0037] Furthermore, the elastic heat sink 3 is made of a heat-conducting metal material, and is evenly distributed around the shell 201 . One end of the elastic heat sink 3 is connected to the shell 201 , and the other end is connected to the inner wall of the outer shell 1 . The elastic heat sink 3 extends along the length direction of the shell 201 .
[0038] Specifically, Figure 1 As shown, heat-conducting metal is selected as the material of the elastic heat sink 3, such as copper, aluminum or their alloys. These materials have excellent thermal conductivity and can quickly transfer the heat on the shell 201 to the shell 1 and the surrounding environment. At the same time, under the premise of heat conduction, they also have a certain rebound ability, which can ensure the stability of the variable frequency motor 2 during operation and buffer the vibration of the variable frequency motor 2 itself and the vibration caused by the vibrating punch 10. Compared with non-metallic materials, heat-conducting metal can more effectively reduce the temperature of the variable frequency motor 2 and improve its working stability and life. The elastic heat sink 3 is distributed along the circumference of the shell 201, ensuring the uniform transfer of heat on the surface of the shell 201. This distribution method avoids the accumulation of heat in certain areas, making the temperature distribution of the entire shell 201 more uniform, thereby improving the heat dissipation efficiency. The elastic heat sink 3 extends along the length direction of the shell 201, forming a series of heat conduction paths. These paths not only increase the area of heat conduction, but also enable heat to be quickly transferred along the length direction of the shell 201, further improving the heat dissipation effect. The elastic heat sink 3 is used as a medium to connect the shell 201 and the housing 1. Its elastic characteristics can absorb and buffer vibration and impact, reducing the direct impact on the variable frequency motor 2. This elastic connection not only improves the overall stability of the vibrator, but also extends the service life of the motor and other components. Although the elastic heat sink 3 has a certain elasticity, it can also provide sufficient fastening force to ensure a tight connection between the shell 201 and the housing 1. This fastening effect helps prevent impurities such as water and dust from entering the motor and protect the safe operation of the motor.
[0039] Furthermore, the elastic heat sink 3 includes a first metal sheet 301 and a second metal sheet 302 . The first metal sheet 301 is adaptively connected to the outer wall of the shell 201 , and the second metal sheet 302 is adaptively connected to the inner wall of the shell 1 . A thermally conductive elastic portion is provided between the first metal sheet 301 and the second metal sheet 302 .
[0040] Specifically, Figure 2As shown, the first metal sheet 301 and the second metal sheet 302 are both arc-shaped sheets with a certain thickness and can bear a certain lateral pressure. The first metal sheet 301 is connected to the outer wall of the shell 201 in an adaptive manner. As the main contact surface between the elastic heat sink 3 and the shell 201, it is responsible for quickly transferring the heat on the shell 201 to the elastic heat sink 3. Since the first metal sheet 301 is tightly fitted with the outer wall of the shell 201, the high efficiency of heat transfer can be ensured. The second metal sheet 302 is connected to the inner wall of the shell 1 in an adaptive manner. It further disperses the heat transferred from the first metal sheet 301 to the shell 1 and releases the heat to the surrounding environment through the heat dissipation area of the shell 1. The close connection between the second metal sheet 302 and the inner wall of the shell 1 also ensures the continuity and high efficiency of heat transfer. The heat-conductive elastic part is located between the first metal sheet 301 and the second metal sheet 302. The heat-conductive elastic part not only has excellent heat conductivity, which can ensure the smooth transfer of heat between the first metal sheet 301 and the second metal sheet 302, but also has a certain elasticity, which can absorb and buffer the vibration from the vibrating head 10, and effectively protect the motor. The heat-conductive metal material and the tight connection method ensure that the heat can be transferred and released quickly and efficiently. The elastic design of the heat-conductive elastic part enables the elastic heat sink 3 to absorb and buffer vibration and impact, thereby improving the stability and reliability of the entire structure.
[0041] Furthermore, the thermally conductive elastic part includes a first elastic thermally conductive sheet 303, a second elastic thermally conductive sheet 304, and a third elastic thermally conductive sheet 305. Two first elastic thermally conductive sheets 303 are provided and are symmetrically arranged, and two second elastic thermally conductive sheets 304 are provided and are symmetrically arranged. The first elastic thermally conductive sheet 303 is located on the outside of the second elastic thermally conductive sheet 304, one end of the first elastic thermally conductive sheet 303 is connected to the first metal sheet 301, and the other end is connected to the second metal sheet 302, one end of the second elastic thermally conductive sheet 304 is connected to the first metal sheet 301, and the other end is connected to the third elastic thermally conductive sheet 305, and both ends of the third elastic thermally conductive sheet 305 are connected to the second metal sheet 302.
[0042] Furthermore, the first elastic heat conductive sheet 303 is bent at an obtuse angle, the second elastic heat conductive sheet 304 is in an arc shape, and the third elastic heat conductive sheet 305 is in an arch shape.
[0043] Specifically, Figure 2As shown, two first elastic heat-conducting sheets 303 are provided and are symmetrically arranged, and are symmetrically arranged with the center line of the first metal sheet 301 as the axis. One end of the first elastic heat-conducting sheet 303 is connected to the outer side of the first metal sheet 301, and the other end is connected to the inner side of the second metal sheet 302, which not only ensures the smooth transfer of heat, but also improves the stability of the structure through the symmetrical arrangement. In addition, the first elastic heat-conducting sheet 303 is designed to be bent at an obtuse angle, and the obtuse angle opening of the first elastic heat-conducting sheet 303 faces outward, which increases the elasticity of the first elastic heat-conducting sheet 303, can better buffer the vibration from the vibrating punch 10, can better adapt to the small gap or shape change between the shell 201 and the outer shell 1, and improve the stability of the variable frequency motor 2.
[0044] The second elastic heat-conducting sheet 304 is also provided with two and symmetrically arranged, and is also symmetrically arranged with the center line of the first metal sheet 301 as the axis. One end of the second elastic heat-conducting sheet 304 is connected to the outside of the first metal sheet 301, and the other end is connected to the inside of the third elastic heat-conducting sheet 305. The second elastic heat-conducting sheet 304 is located inside the two first elastic heat-conducting sheets 303. Compared with the first elastic heat-conducting sheet 303, the second elastic heat-conducting sheet 304 is designed to be arc-shaped. This arc-shaped design enables the second elastic heat-conducting sheet 304 to better fit the curvature change of the shell 201 and the housing 1 during the heat conduction process, reduce thermal resistance, and improve heat conduction efficiency. At the same time, the arc-shaped structure also gives the second elastic heat-conducting sheet 304 stronger elasticity and adaptability.
[0045] The third elastic heat conductive sheet 305 is in an arch shape, that is, it is convexly spherical toward the side of the shell 201, and both ends are connected to the second metal sheet 302. The arch design not only enhances the structural strength of the third elastic heat conductive sheet 305, but also enables it to better withstand the heat conduction pressure from the second elastic heat conductive sheet 304. At the same time, the arch structure also has a certain elasticity, which can buffer the vibration force transmitted from the second elastic heat conductive sheet 304 when the vibrating head 10 vibrates.
[0046] By combining the multi-layer and multi-shaped thermally conductive elastic sheets, a complex and efficient heat conduction path is formed, ensuring that heat can be transferred from the shell 201 to the housing 1 quickly and evenly.
[0047] Each layer of the heat-conducting elastic sheet has a certain elasticity, and can absorb and buffer the vibration and impact caused by the vibrating punch 10 and the small gap or shape change between the shell 201 and the outer shell 1, so as to maintain a stable connection state.
[0048] Furthermore, a plurality of fourth elastic heat-conducting sheets 306 are disposed between the third elastic heat-conducting sheet 305 and the second metal sheet 302 .
[0049] Specifically, the addition of the fourth elastic heat conductive sheet 306 increases the path and area of heat conduction, so that heat can be transferred more quickly and evenly from the third elastic heat conductive sheet 305 to the second metal sheet 302, and then diffused to the housing 1, which helps to further improve the heat dissipation efficiency and reduce the operating temperature of the variable frequency motor 2.
[0050] The distribution of the plurality of fourth elastic heat conductive sheets 306 makes the connection between the third elastic heat conductive sheet 305 and the second metal sheet 302 more stable. They not only share the pressure of heat conduction, but also absorb and buffer the vibration force of the vibrating punch 10 through their elastic properties.
[0051] The fourth elastic heat conductive sheet 306 also has a certain elasticity, which enables the elastic heat sink 3 to better adapt to the small gap or shape change between the shell 201 and the housing 1. Whether in the installation process or in the use process, this adaptability can ensure the tight connection between the elastic heat sink 3 and the shell 201 and the housing 1, and maintain efficient heat conduction. By adjusting the number, shape and distribution of the fourth elastic heat conductive sheet 306, the heat dissipation effect can be further optimized. For example, the fourth elastic heat conductive sheet 306 of different shapes and sizes can be designed according to the specific shape and heat dissipation requirements of the shell 201 and the housing 1 to achieve more uniform and efficient heat distribution.
[0052] Furthermore, the elastic heat sink 3 is wrapped with a rubber layer on the outside.
[0053] Specifically, the rubber layer serves as an external protective layer, which can effectively isolate dust, moisture and other impurities in the external environment and prevent them from invading the elastic heat sink 3, thereby keeping it clean and dry. This is of great significance for extending the service life of the elastic heat sink 3 and preventing problems such as corrosion and short circuit. The rubber layer can also improve the buffering and seismic isolation performance of the elastic heat sink 3.
[0054] The rubber layer has good shock absorption and noise reduction properties. During the operation of the variable frequency motor 2, due to the existence of vibration and mechanical stress, the elastic heat sink 3 may be affected by certain impacts and noise. The existence of the rubber layer can absorb and disperse these impact energies, reduce vibration transmission, and reduce noise levels, providing a more stable and quiet operating environment for the motor.
[0055] The rubber layer also has certain insulation properties. In electrical equipment, insulation performance is crucial. It can prevent safety hazards such as current leakage and short circuit. By wrapping the elastic heat sink 3 with a rubber layer, its insulation performance can be further enhanced to ensure the safety and reliability of the motor during operation.
[0056] The rubber layer has a certain elasticity and softness, which makes the elastic heat sink 3 more flexible and adaptable when dealing with shells 201 and housings 1 of different shapes and sizes. Whether it is a tiny gap during installation or a shape change caused by temperature changes during use, the rubber layer can provide sufficient buffering and adaptability to ensure a tight connection and efficient heat conduction between the elastic heat sink 3 and the shell 201 and housing 1.
[0057] Example 3
[0058] Furthermore, a nozzle 8 is connected to the water pipe 5 , and the nozzle 8 is located at the upper end of the fixing plate 11 . The nozzle 8 sprays tap water toward the housing 1 of the vibrator.
[0059] In this embodiment, a circle of injection pipes 7 are connected to the water pipe 5. The injection pipes 7 are fixed to the top of the fixing plate 11 and are located in the circumference of the outer shell 1. The nozzle 8 is arranged on the injection pipe 7 and faces the area where the variable frequency motor 2 is installed in the outer shell 1. The injection point is located at the tail end of the deformation motor. The tail end of the variable frequency motor 2 is higher than the position of its output end. In this way, the sprayed tap water can flow from top to bottom on the outer shell 1. By spraying tap water on the outer shell 1 of the vibrator, the principle of heat absorption by evaporation of water can be used to directly take away part of the heat on the outer shell 1, thereby assisting the elastic heat sink 3 to dissipate heat. This direct cooling method can significantly reduce the temperature of the outer shell 1 and improve the heat dissipation efficiency.
[0060] The sprayed tap water will form water mist or water flow. These water molecules will evaporate quickly after contacting the shell 1, forming a local convection effect. This convection effect helps to accelerate the flow of air around the shell 1, improve the heat exchange efficiency between the air and the shell 1, and further reduce the temperature of the shell 1.
[0061] During the operation of the vibrator, dust, oil, dirt and other dirt may accumulate on the shell 1. These dirt will not only affect the heat dissipation effect, but may also cause corrosion to the equipment. By regularly spraying tap water on the shell 1, these dirt can be effectively removed to maintain the cleanliness and heat dissipation performance of the shell 1.
[0062] The nozzle 8 is located at the upper end of the fixing plate 11 and sprays toward the housing 1 of the vibrator. This design ensures that the tap water can be accurately sprayed onto the housing 1 to avoid waste and accidental spraying onto other components. In practical applications, it may be necessary to control the flow rate and spraying time of the water flow through devices such as valves or water pumps to ensure that the expected heat dissipation or cleaning effect is achieved without causing waste of water resources or damage to the equipment. Since the use of water is involved, it is necessary to ensure that the interior of the vibrator and its related electrical components have good waterproof properties to prevent water from penetrating and causing short circuits or damage.
