[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0018] like Figure 1-Figure 3 The figure shows the first embodiment of the sound insulation and noise reduction device for a power generation vehicle according to the present invention.

[0019] The sound insulation and noise reduction device for the power generation vehicle in this embodiment includes: a support frame 1 and a sound insulation sleeve 2 that is detachably mounted on the support frame 1. The support frame 1 includes: a top frame T composed of multiple horizontal supports 11 connected end to end and multiple vertical supports 12 connected to the top frame T.

[0020] The vertical bracket 12 includes: a bottom sleeve 121 and a top pipe 122 which is telescopically connected to the bottom sleeve 121. Movable locking pins 123 are slidably provided on opposite sides of the bottom sleeve 121. An elastic member 126 is provided between the movable locking pin 123 and the bottom sleeve 121, which is used to push the end of the movable locking pin 123 out of the bottom sleeve 121. The end of the movable locking pin 123 connected to the elastic member 126 is an inclined surface 123a, and the other opposite end is a spherical surface 123b.

[0021] The function of the inclined surface 123a is: during use, when the elastic member 126 ages and the elastic force is insufficient, the displacement of the movable locking pin 123 will change. Therefore, in order to realize the displacement change of the movable locking pin 123, the adjusting screw 124 can also contact the inclined surface 123a of the movable locking pin 123 to achieve tightening.

[0022] The function of the spherical surface 123 b is: in order to save effort when the top pipe 122 is pulled down, the spherical surface 123 b of the movable locking pin 123 can be partially inserted into the pin slot 1221 under the action of the pre-tightening force of the elastic member 126 .

[0023] Adjusting members for resisting the movable locking pin 123 are respectively provided on opposite sides of the bottom sleeve 121 , and a plurality of latch grooves 1221 are respectively provided on opposite sides of the top tube 122 . The plurality of latch grooves 1221 on any side are arranged in the same straight line along the length direction of the top tube 122 .

[0024] During implementation, the top pipe 122 is inserted into the bottom sleeve 121, and the adjusting member pushes the movable locking pin 123 laterally out of the bottom sleeve 121 and inserts it into the latch groove 1221 at different positions of the top pipe 122, so that the top pipe 122 is fixedly connected to the bottom sleeve 121 to adjust the height of the top pipe 122 relative to the bottom sleeve 121, wherein: the movable locking pin 123 is provided with a pre-tightening force in the direction of the latch groove.

[0025] In specific implementation, by changing the height of the multiple vertical brackets 12 of the support frame 1, the sound insulation and noise reduction device for the power generation vehicle can adapt to power generation vehicles of different heights. The sound insulation sleeve 2 in this embodiment includes multiple sound insulation cotton layers stacked in sequence, and the outermost sound insulation cotton layer is provided with an Oxford waterproof layer.

[0026] In this embodiment, the support frame 1 is rectangular in shape as a whole, and the top frame T is connected end to end by four horizontal brackets 11. There are four vertical brackets 12, each of which can be adjusted in height. The following takes any vertical bracket 12 as an example to illustrate how the top pipe 122 can be adjusted in height relative to the bottom sleeve 121.

[0027] The bottom sleeve 121 has two opposite sides respectively provided with a slidable active lock pin 123 and an adjustable position member. The top pipe 122 has two opposite sides respectively provided with a plurality of latch slots 1221. In this embodiment, the plurality of latch slots 1221 on both sides of the top pipe 122 are symmetrically arranged to correspond in position to the positions of the active lock pins 123 on the opposite sides of the bottom sleeve 121.

[0028] Preferably, the multiple latch slots 1221 on either side are arranged on the same straight line along the length direction of the top pipe 122, and the multiple latch slots 1221 on either side are arranged equidistantly, so that the height of the vertical bracket 12 can be evenly adjusted.

[0029] Furthermore, the adjusting member includes: an adjusting screw 124 connected to the inclined surface 123a of the movable locking pin 123 and a knob 125 connected to the adjusting screw 124, wherein: the adjusting screw 124 is threadedly connected to the bottom sleeve 121, and the centerline direction of the adjusting screw 124 is perpendicular to the centerline direction of the movable locking pin 123. By turning the knob 125 to change the position of the adjusting screw 124 in the bottom sleeve 121, the adjusting screw 124 presses against the movable locking pin 123 to be fastened to the latch groove 1221.

[0030] In the specific implementation of the sound insulation and noise reduction device for power generation vehicles in this embodiment, when the knob 125 is rotated, the adjusting screw 124 is separated from the inclined surface 123a. At this time, the spring member 126 maintains a certain pre-tightening force, which can keep the movable lock pin 123 in the latch groove 1221, and will not cause the top pipe 122 to drop suddenly, thereby causing harm to the operator. When the operator pulls the top pipe downward, the end of the movable lock pin 123 is set as a spherical surface 123b, which can be separated from the latch groove 1221, thereby allowing the top pipe 122 to move with the bottom sleeve 121, thereby adjusting the height.

[0031] When adjusted to a suitable position, the spring member 126 can press the movable lock pin 123 to automatically align with the latch slot 1221 to achieve pre-tightening. At this time, it is necessary to continue to rotate the adjusting screw 124 to make the end of the adjusting screw 124 abut against the inclined surface 123a to limit the movement of the movable lock pin 123, thereby achieving the tightening between the top pipe 122 and the bottom sleeve 121.

[0032] A sound insulation and noise reduction device for a power generation vehicle implemented in the present invention has the following beneficial effects: the sound insulation and noise reduction device for a power generation vehicle comprises: a support frame and a detachable sound insulation sleeve sleeved on the support frame, the support frame comprises: a top frame composed of a plurality of horizontal brackets connected end to end and a plurality of vertical brackets connected to the top frame; the vertical bracket comprises: a bottom sleeve and a telescopic top pipe connected to the bottom sleeve, movable locking pins are slidably provided on opposite sides of the bottom sleeve, and adjustment means for resisting the movable locking pins are respectively provided on opposite sides of the bottom sleeve. The top pipe is inserted into the bottom sleeve, and the adjusting member pushes the movable locking pin out of the bottom sleeve laterally and inserts it into the locking pin slots at different positions of the top pipe, so that the top pipe is fixedly connected with the bottom sleeve, so as to adjust the height of the top pipe relative to the bottom sleeve, wherein: the movable locking pin is provided with a pre-tightening force in the direction of the locking pin slot, so as to perform sound insulation and shielding on power generation vehicles of different heights; the structure is simple, and it is convenient for disassembly, assembly and transportation.
