Abstract
The utility model relates to a municipal works technical field just discloses a municipal road is with stabilizing sound insulation protective screen, include, the base, there is the vertical baffle that gives sound insulation that is provided with on base upper portion, the baffle middle part that gives sound insulation is provided with the installation cavity, the top of installation cavity hangs down and is provided with the balancing weight. The utility model discloses in, when the baffle produces the swing under the effect of sound wave or wind, the balancing weight of hanging down in the installation cavity produces a reverse effort because inertial effect, reverse motion to play the damping effect, thereby reduce the baffle amplitude of swaying that gives sound insulation, avoid it to rock the too big damage that causes of amplitude, influence road traffic safety.
Description
Technical Field
The utility model relates to a municipal works technical field specifically is a stabilizing sound insulation protective screen for town road.
Background
Sound barriers, also known as sound-insulating walls, are one of the ways to mitigate noise and are the most effective way to mitigate noise from road, railway and industrial sources. Most of the products are used for roads, and noise and dust disturbance to pedestrians or nearby roads are reduced. Present sound barrier can take place obviously to rock when meetting strong wind, strong noise or forming same frequency resonance to there is the damage then influences traffic safety's risk.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a municipal road is with stabilizing sound insulation protective screen, include, the base, there is the vertical baffle that gives sound insulation that is provided with on base upper portion, the baffle middle part that gives sound insulation is provided with the installation cavity, the top of installation cavity hangs down and is provided with the balancing weight.
Preferably, the inner side wall of the mounting cavity is provided with sound absorption cotton.
Preferably, the outer side of the balancing weight is wrapped with a first rubber sleeve.
Preferably, a first connecting ring is arranged at the bottom of the balancing weight, a second connecting ring is arranged at the bottom of the mounting cavity, and an elastic pull rope is connected between the first connecting ring and the second connecting ring.
Preferably, a buffer structure is arranged at the bottom of the balancing weight.
Preferably, the buffering structure comprises a ring body, the ring body is fixed below the balancing weight through a connecting rod, a plurality of contact plates which are uniformly distributed in an annular mode are hinged to the periphery of the ring body, the contact plates are arranged obliquely upwards, and the inner side faces of the contact plates are connected with the top face of the ring body through elastic pieces.
Preferably, the contact plate is sleeved with a second rubber sleeve.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention.
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.
Drawings
FIG. 1 is a schematic view of the actual and integral installation structure of the present invention;
fig. 2 is a schematic view of the buffering structure of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
As shown in figure 1, a municipal administration road is with stabilizing sound insulation protective screen, includes, base 1, and there is vertical sound insulation reflecting plate 2 that is provided with on base 1 upper portion, and sound insulation reflecting plate 2 middle part is provided with installation cavity 3, and the top of installation cavity 3 hangs and is provided with balancing weight 4. In the present embodiment, the installation cavity 3 is provided at an upper portion of the soundproof reflecting plate 2.
In order to avoid the generation of cavity noise in the installation cavity, in the present embodiment, the inner side wall of the installation cavity 3 is provided with sound-absorbing cotton 5.
In order to avoid the balancing weight shaking amplitude to cause striking destruction to the sound insulation reflecting plate under extreme service environment, in this embodiment, the outside parcel of balancing weight 4 is provided with first gum cover 6.
In order to limit the shaking amplitude of the balancing weight, in the present embodiment, the first connecting ring 7 is disposed at the bottom of the balancing weight 4, the second connecting ring 8 is disposed at the bottom of the mounting cavity 3, and the elastic pulling rope 9 is disposed between the first connecting ring 7 and the second connecting ring 8.
The working principle and the beneficial effects of the technical scheme are as follows:
this embodiment is when using, and the base is through passing through bolt and ground fixed connection with ground, and when baffle 2 produced the swing under the effect of sound wave or wind, the balancing weight 4 of hanging down in the installation cavity 3 produced a reverse effort because inertial effect, reverse motion to play the damping effect, thereby reduce baffle 2 amplitude of swaying that gives sound insulation, avoid it to rock the too big damage that causes of amplitude, influence road traffic safety.
Example two
As shown in fig. 2, in this embodiment, a buffer structure 10 is disposed at the bottom of the counterweight block 4, the buffer structure 10 includes a ring body 10-1, the ring body 10-1 is fixed below the counterweight block 4 through a connecting rod 10-2, a plurality of contact plates 10-3 are hinged around the ring body 10-1 and disposed uniformly in a ring shape, the contact plates 10-3 are disposed obliquely upward, and an inner side surface of the contact plates 10-3 is connected to a top surface of the ring body 10-1 through elastic pieces 10-4. The contact plate 10-3 is sleeved with a second rubber sleeve 10-5.
The working principle and the beneficial effects of the technical scheme are as follows:
when the shaking amplitude of the balancing weight is too large, the contact plate 10-3 is firstly contacted with the inner side wall of the mounting cavity, under the action of the elastic sheet 10-4, the contact speed is reduced, the impact force is reduced, the buffering effect is achieved, and the damage to the sound insulation reflecting plate 2 is avoided.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
