[0013] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the protection scope of the present application.

[0014] As Figures 1-3 ​As shown, it is the first embodiment of the sound insulation and noise reduction device for the power generation vehicle of the present application.

[0015] The sound insulation and noise reduction device for the power generation vehicle in the present embodiment comprises a support frame 1 and a detachable sound insulation sleeve 2 sleeved on the support frame 1, and the support frame 1 comprises a top frame T composed of a plurality of horizontal supports 11 connected end to end and a plurality of vertical supports 12 connected to the top frame T.

[0016] The vertical support 12 comprises a bottom sleeve 121 and a telescopic top pipe 122 connected in the bottom sleeve 121, and the opposite sides of the bottom sleeve 121 are slidably provided with movable locking pins 123. A spring 126 is arranged between the movable locking pin 123 and the bottom sleeve 121 for abutting the end of the movable locking pin 123 out of the bottom sleeve 121, and the end of the movable locking pin 123 connected to the spring 126 is a bevel 123a, and the opposite end is a spherical surface 123b.

[0017] The function of the bevel 123a is that in the process of use, when the spring 126 ages and the elastic force is insufficient, the displacement of the movable locking pin 123 will change, so that the adjusting screw 124 can also be in contact with the bevel 123a of the movable locking pin 123 when the displacement of the movable locking pin 123 changes, thereby achieving fastening.

[0018] The function of the spherical surface 123b is to save labor when the top pipe 122 is pulled down, and the spherical surface 123b of the movable locking pin 123 can be partially inserted into the pin slot 1221 under the pre-tightening force of the spring 126.

[0019] The opposite sides of the bottom sleeve 121 are respectively provided with adjusting members for abutting the movable locking pin 123, and the opposite sides of the top pipe 122 are respectively provided with a plurality of pin slots 1221, and the plurality of pin slots 1221 on any side are arranged on the same straight line along the length direction of the top pipe 122.

[0020] In implementation, the top pipe 122 is inserted into the bottom sleeve 121, the adjusting member abuts the movable locking pin 123 transversely out of the bottom sleeve 121 and is inserted into the pin slot 1221 at different positions of the top pipe 122, and the top pipe 122 is fixedly connected with 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 pin slot.

[0021] In specific implementation, by changing the height of the plurality of vertical supports 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 the present embodiment comprises a plurality of sequentially stacked sound insulation cotton layers, and the outermost sound insulation cotton layer is provided with an Oxford waterproof layer.

[0022] In this embodiment, the support frame 1 is in the shape of a rectangle, the top frame T is formed by four horizontal supports 11 connected end to end, and four vertical supports 12 are provided, each of which can be adjusted in height. The following describes the height adjustment of the top pipe 122 relative to the bottom sleeve pipe 121 by taking any one of the vertical supports 12 as an example.

[0023] The opposite sides of the bottom sleeve pipe 121 are respectively provided with a movable locking pin 123 and an adjustable adjusting member. The opposite sides of the top pipe 122 are respectively provided with a plurality of pin slots 1221. In this embodiment, the plurality of pin slots 1221 on the opposite sides of the top pipe 122 are symmetrical and correspond to the positions of the movable locking pins 123 on the opposite sides of the bottom sleeve pipe 121.

[0024] Preferably, the plurality of pin slots 1221 on each side are arranged in the same straight line along the length direction of the top pipe 122, and the plurality of pin slots 1221 on each side are equidistantly arranged. In this way, the height of the vertical support 12 can be uniformly adjusted.

[0025] Further, 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. The adjusting screw 124 is threadedly connected to the bottom sleeve pipe 121, and the center line direction of the adjusting screw 124 is perpendicular to the center line direction of the movable locking pin 123. By rotating the knob 125, the position of the adjusting screw 124 in the bottom sleeve pipe 121 is changed, and the adjusting screw 124 abuts against the movable locking pin 123 to fasten it with the pin slot 1221.

[0026] In the specific implementation of the sound insulation and noise reduction device for the power generation vehicle 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, so that the movable locking pin 123 is kept in the pin slot 1221 and cannot suddenly drop the top pipe 122, thereby causing harm to the operator. When the operator pulls the top pipe downward, the end of the movable locking pin 123 is provided in the form of a spherical surface 123b, which can be separated from the pin slot 1221, thereby allowing the top pipe 122 to move relative to the bottom sleeve pipe 121 and adjusting the height.

[0027] When the appropriate position is adjusted, the movable locking pin 123 can be automatically aligned with the pin slot 1221 due to the action of the spring member 126, thereby achieving pre-tightening. At this time, the adjusting screw 124 needs to be further rotated to abut the end of the adjusting screw 124 against the inclined surface 123a, thereby limiting the movement of the movable locking pin 123 and achieving the fastening between the top pipe 122 and the bottom sleeve pipe 121.

[0028] The utility model discloses a sound insulation and noise reduction device for power generation car has the beneficial effect that: sound insulation and noise reduction device for power generation car includes: support frame and detachable sleeve joint on the support frame of sound insulation cover, support frame includes: by the first end -to-end of a plurality of horizontal support frame and a plurality of vertical support frame of connecting on top frame, vertical support frame includes: bottom sleeve and telescopic connection in the top pipe of bottom sleeve, the opposite sides of bottom sleeve are slidably provided with movable lock pin, the opposite sides of bottom sleeve are provided with the adjusting piece for the resistance of movable lock pin respectively, the opposite sides of top pipe are provided with a plurality of bolt slot respectively, and a plurality of bolt slots of any side are arranged on the same straight line along the length direction of top pipe, top pipe is inserted in bottom sleeve, and adjusting piece is transversely inserted in the bolt slot of different position of top pipe with movable lock pin and is taken out from bottom sleeve, and top pipe is fixedly connected with bottom sleeve, is used to adjust the height of top pipe relative to bottom sleeve, wherein: movable lock pin is provided with the pre-tightening force to the direction of bolt slot, can sound insulation shield the power generation car of different height, the structure is simple, and it is favorable to dismount and transport.
