DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides a shock-absorbing protection structure for transporting a diesel generator set, comprising a base 1, on which a first shock-absorbing mechanism 2 for assisting the diesel generator set in shock absorption is arranged, the first shock-absorbing mechanism 2 comprising a fixing seat 25 fixed at the middle part of the base 1, a mounting rod 21 fixed at one side of the fixing seat 25, a compression spring 22 fixed at one end of the fixing rod 21, a slide rod 24 penetrating the fixing seat 25 fixed at one end of the compression spring 22, and a magnetic rod 26 surrounded by the compression spring 22 installed at one end of the slide rod 24; the fixing seat 25 is fixedly installed at the middle part of the base 1, and the fixing rod 21 is fixedly installed at one side of the fixing seat 25, a connecting plate is installed at the fixing rod 21, a mounting plate 23 is installed at one end of the slide rod 24, two ends of the compression spring 22 are fixedly connected to the connecting plate and the mounting plate 23 respectively, one end of the magnetic rod 26 is fixedly connected to the mounting plate 23 and moves synchronously with the mounting plate 23, and one end of the slide rod 24 is connected to the fixing seat 25 penetrating; See also Figures 1 to 3 as well as Fig.10 As shown, the diesel generator set is installed on the base 1, connected to the bottom of the diesel generator set through the mounting plate 23, and then connected to the base 1 through a crane or a forklift, and the diesel generator set is loaded onto the transfer vehicle. The base 1 is connected to the crane or the forklift to assist in loading the diesel generator set, which can avoid damage to the diesel generator set when the crane or the forklift is directly connected to the diesel generator set for loading; in addition, the position where the mounting plate 23 is connected to the bottom of the diesel generator set can be selected according to actual conditions; When encountering bumps or sudden braking and acceleration during the rotation process, the diesel generator set inside the rotating vehicle shakes. At this time, the diesel generator set squeezes or pulls the compression spring 22 through the mounting plate 23, thereby the compression spring 22 is stretched or squeezed to play a buffering and shock absorbing effect, which greatly reduces the damage to the diesel generator set during bumps or sudden braking and acceleration, and plays a protective role for the diesel generator set; A second shock absorbing mechanism 3 is installed on the fixed seat 25 to assist the diesel generator set in secondary shock absorption when cooperating with the compression spring 22 for shock absorption. The second shock absorbing mechanism 3 includes a first piston cylinder 31 fixed to the middle part of the base 1. The bottom piston of the first piston cylinder 31 has a first piston rod 32 for piston-like movement. A vertical rod 310 connected to the first piston rod 32 is installed on one side of the first piston cylinder 31. During the process in which the slide rod 24 is driven to reciprocate by the compression spring 22, the slide rod 24 drives the first piston rod 32 to move vertically inside the first piston cylinder 31 through the vertical rod 310. A limiting plate 39 is fixed on one side of the first piston cylinder 31, and the limiting plate 39 is fixedly connected to the base 1. One end of the second piston cylinder 33 is connected to A connecting pipe 36, one end of which is connected to the first piston cylinder 31, a gear shaft 37 is rotated on the fixed seat 25, gears are installed at both ends of the gear shaft 37, a first gear tooth 38 meshing with the gear on the gear shaft 37 is installed on the slide rod 24, the second gear tooth on the connecting pipe 36 meshes with the gear at the other end of the gear shaft 37, the vertical rod 310 is connected through the limiting plate 39, a push rod 35 is fixed at one end of the mounting plate 23, and the push rod 35 is movably connected to the second piston rod 34; one side of the first piston cylinder 31 is connected to the second piston cylinder 33, the internal piston of the second piston cylinder 33 moves with the second piston rod 34, and one end of the slide rod 24 moves to a certain position and pushes the second piston rod 34 to move; See also Figures 3 to 9 As shown, when the diesel generator set shakes, the mounting plate 23 moves to buffer the vibration, and the mounting plate 23 drives the slide bar 24 to move. The slide bar 24 penetrates the fixing seat 25, and the slide bar 24 meshes with the gear shaft 37 through the first gear teeth 38. When the slide bar 24 moves, the gear shaft 37 is driven to rotate. The rotation of the gear shaft 37 meshes with the gear at the other end of the gear shaft 37 through the second gear teeth on the connecting pipe 36. During the rotation of the gear shaft 37, the vertical rod 310 is driven to move. The vertical rod 310 moves on the limiting plate 39. The vertical rod 310 drives the first piston rod 32 at one end to move. Since the first piston cylinder 31 is a sealed space inside, one end of the first piston rod 32 further plays a buffering and shock absorbing effect when the piston moves inside the first piston cylinder 31; thus, when the compression spring 22 is stretched or squeezed, the internal pressure of the first piston cylinder 31 changes by following the change of the compression spring 22. Through the change of the elastic force of the compression spring 22 and the change of the internal pressure of the first piston cylinder 31, the double buffering and shock absorbing means greatly improve the shock absorbing effect of the diesel generator set; In addition, the greater the degree to which the compression spring 22 is squeezed or stretched, the greater the corresponding pressure change inside the first piston cylinder 31. Therefore, when the vibration amplitude of the diesel generator set is greater, the elastic force change of the compression spring 22 and the pressure change inside the first piston cylinder 31 will have a stronger shock-absorbing and buffering effect on the diesel generator set; thereby, it can adapt to bumpy roads of various degrees; in addition, the direction of stretching or squeezing of the compression spring 22 is designed to be perpendicular to the direction of movement of the first piston rod 32, which can cope with vibrations in different directions and improve its vibration reduction effect.

[0020] In addition, when the vibration amplitude of the diesel generator set reaches a certain level, refer to Figure 2 Figure 3 As shown, the mounting plate 23 drives the push rod 35 to move, so that the push rod 35 squeezes the second piston rod 34 to move, so that the second piston rod 34 moves in a piston-like manner inside the second piston cylinder 33, and through the one-way valve design on the second piston cylinder 33, the internal gas of the second piston cylinder 33 is squeezed into the first piston cylinder 31 through the connecting pipe 36, thereby increasing the pressure inside the first piston cylinder 31, thereby further increasing the vibration reduction and buffering effect of the first piston cylinder 31 according to the vibration amplitude; A cooling mechanism 4 is installed at one end of the mounting rod 21. The cooling mechanism 4 includes a coil 41 installed on the connecting plate. One end of the magnetic rod 26 is surrounded by the coil 41. When the magnetic rod 26 moves along the mounting plate 23, the magnetic rod 26 cuts the magnetic flux lines when it moves inside the coil 41. A motor 42 is installed at one end of the mounting rod 21. The motor 42 is electrically connected to the coil 41 at one end of the mounting rod 21, and a fan blade 43 is installed at the output end of the motor 42. See also Figures 6 to 9 As shown, in the process of the mounting plate 23 moving back and forth under the elastic force of the compression spring 22, the mounting plate 23 drives the magnetic rod 26 to move back and forth, so that one end of the magnetic rod 26 moves back and forth inside the coil 41 and cuts its magnetic flux lines to generate electricity. Because the motor 42 is electrically connected to the coil 41, the motor 42 is provided with power in the process of one end of the magnetic rod 26 continuously cutting the magnetic flux lines of the coil 41, so that it can drive the fan blades 43 to rotate. The rotation of the fan blades 43 can accelerate the gas flow at the bottom of the diesel generator set, avoid heat generated by vibration or the bottom temperature affecting the service life of the diesel generator set; at the same time, the energy of vibration is utilized to achieve energy-saving effect. It is also noted that in the technical solution, the magnetic rod 26 moves inside the coil 41 and cuts the magnetic flux lines to generate electricity, which is a mature existing technology.

[0021] Working principle: Install the diesel generator set on the base 1, install the base 1 on the transfer vehicle, and then connect it to the bottom of the diesel generator set through the mounting plate 23; when encountering bumps or sudden braking and acceleration during the rotation process, the diesel generator set inside the rotating vehicle shakes, and at this time the diesel generator set squeezes or pulls the compression spring 22 through the mounting plate 23; When the diesel generator set shakes, the movement of the mounting plate 23 acts as a buffer, and the mounting plate 23 drives the slide bar 24 to move. The slide bar 24 penetrates the fixed seat 25, and the slide bar 24 is meshed with the gear shaft 37 through the first gear teeth 38. When the slide bar 24 moves, it will drive the gear shaft 37 to rotate. The rotation of the gear shaft 37 will be meshed with the gears at the other end of the gear shaft 37 through the second gear teeth on the connecting pipe 36. During the rotation of the gear shaft 37, the vertical rod 310 is driven to move. The vertical rod 310 moves on the limiting plate 39, and the vertical rod 310 drives the first piston rod 32 at one end to move. Since the interior of the first piston cylinder 31 is a sealed space, one end of the first piston rod 32 further plays a buffering and shock absorbing effect when the piston moves inside the first piston cylinder 31; thereby, when the compression spring 22 is stretched or squeezed, the internal pressure of the first piston cylinder 31 changes by following the changes of the compression spring 22; In addition, the greater the degree of compression or stretching of the compression spring 22, the greater the corresponding pressure change inside the first piston cylinder 31. Therefore, when the vibration amplitude of the diesel generator set is greater, the elastic force change of the compression spring 22 and the pressure change inside the first piston cylinder 31 will have a stronger shock-absorbing and buffering effect on the diesel generator set; thus, it can adapt to bumpy roads of various degrees; In addition, when the vibration amplitude of the diesel generator set reaches a certain level, refer to Figure 2 Figure 3 As shown, the mounting plate 23 drives the push rod 35 to move, so that the push rod 35 squeezes the second piston rod 34 to move, so that the second piston rod 34 moves in a piston-like manner inside the second piston cylinder 33, and through the one-way valve design on the second piston cylinder 33, the internal gas of the second piston cylinder 33 is squeezed into the first piston cylinder 31 through the connecting pipe 36, thereby increasing the pressure inside the first piston cylinder 31, thereby further increasing the vibration reduction and buffering effect of the first piston cylinder 31 according to the vibration amplitude; In the process of the mounting plate 23 moving back and forth under the elastic force of the compression spring 22, the mounting plate 23 drives the magnetic rod 26 to move back and forth, so that one end of the magnetic rod 26 moves back and forth on the inner side of the coil 41 and cuts its magnetic flux lines to generate electricity. Because the motor 42 is electrically connected to the coil 41, the motor 42 is provided with electricity in the process of one end of the magnetic rod 26 continuously cutting the magnetic flux lines of the coil 41, so that it can drive the fan blades 43 to rotate. The rotation of the fan blades 43 can speed up the gas flow at the bottom of the diesel generator set to avoid vibration to generate heat or the bottom temperature affecting the service life of the diesel generator set.
