Description

Technical Field

[0001] The present application relates to the technical field of sound insulation screens, and in particular to a sound insulation screen for highways. Background Art

[0002] As an efficient noise control facility, the core function of highway noise screens is to effectively reduce the propagation range of traffic noise through physical blocking, sound reflection and absorption mechanisms. They are usually deployed on both sides of the highway or in the central dividing strip area to reduce the noise interference of traffic activities on surrounding residential areas and the natural environment, and create a quieter living and working environment. Especially in the stage of highway construction and maintenance, noise screens also play a dual role of dust prevention and noise reduction, and their importance is self-evident.

[0003] The prior art soundproof screen design generally includes one or more soundproof panels, which are embedded with sound-absorbing cotton materials on both sides to enhance their sound absorption performance. In addition, pairs of protruding panels are cleverly arranged at the bottom edge of the soundproof panel, and fixing holes are reserved on the panels to facilitate direct anchoring to the ground through fasteners such as bolts, thereby ensuring the stable installation of the soundproof screen.

[0004] However, in the process of transporting and handling the sound insulation screens, especially when facing the need for short-distance displacement, the current operation method is quite cumbersome and inefficient. When migrating over long distances, the sound insulation screens can be stacked and loaded on transport vehicles to achieve efficient transportation. However, in the short-distance moving scenario, a large number of manpower is often required to work together, which is not only time-consuming and labor-intensive, but also increases the complexity of the operation and labor costs, and there is room for improvement. Summary of the invention

[0005] The purpose of this application is to provide a road sound insulation screen to solve the problem of long time consumption and low efficiency when the above-mentioned sound insulation screen is moved over a short distance.

[0006] The present application provides a road noise insulation screen that adopts the following technical solution:

[0007] A road soundproof screen comprises a main body, support plates are fixedly provided on the two opposite side edges of the lower part of the main body, and support holes are provided on the support plates; a clearance gap is provided on the bottom side of the main body, and a moving block that rotates around a vertical plane is rotatably provided inside the clearance gap of the main body, and a plurality of moving wheels are fixedly provided on the side edges of the moving block away from the main body; locking members for limiting the vertical state of the moving block are provided on the two opposite sides of the main body, and the moving wheels protrude from the bottom side surface of the main body when the moving block is in a vertical state, and one side surface of the moving block is flush with the bottom side surface of the main body when the moving block is in a horizontal state.

[0008] By adopting the above technical solution, due to the coordinated arrangement of the moving block, the moving wheel and the locking piece, when the sound insulation screen needs to be moved a short distance, the moving block is adjusted to a vertical state and locked by the locking piece, so that the moving wheel protrudes from the bottom side of the main body, so that the sound insulation screen can be moved with fewer workers, thereby improving the efficiency of short-distance movement; when the sound insulation screen is installed and applied, first release the locking piece from limiting the vertical state of the moving block, and then adjust the moving block to a horizontal state, in which the lower side of the moving block is flush with the bottom side of the main body, and finally use bolts to penetrate the support holes on the support plate to fix the sound insulation screen on the installation surface.

[0009] Optionally, a wear-resistant pad is fixedly provided on the vertical outer side surface of the moving block in the vertical state.

[0010] By adopting the above technical solution, when the sound insulation screen is installed and applied, the moving block is in a horizontal state. Due to the matching setting of the wear-resistant pad, the possibility of wear caused by friction between the side surface of the moving block and the installation surface in this state is reduced, thereby extending the service life of the moving block.

[0011] Optionally, the locking member includes a locking rod rotatably arranged on the side of the main body, and the locking rod can be rotated, adjusted and fixed along the vertical side of the main body; when the moving block is in a vertical state, the locking rod can be rotated downward toward the side of the main body and fit with the vertical side of the moving block.

[0012] By adopting the above technical solution, when the moving block is in a vertical state, due to the installation setting of the locking rod, the locking rod is rotated downward as a whole, so that the side of the locking rod facing the main body is in contact with the vertical side of the moving block, thereby reducing the possibility of swinging or loosening of the moving block in the vertical state.

[0013] Optionally, a guiding slope is provided on the side edge of the locking rod facing the main body.

[0014] By adopting the above technical solution, due to the setting of the guiding inclined surface on the locking rod, it is convenient for the locking rod to rotate to a state in which it is in contact with the vertical side surface of the moving block.

[0015] Optionally, an elastic clip is provided on the side of the locking rod facing the main body, a first positioning groove for the elastic clip to be inserted into is provided on the main body, and a second positioning groove for the elastic clip to be inserted into is provided on the wear-resistant pad.

[0016] By adopting the above technical solution, when the locking rod is rotated upward to a horizontal state, the elastic clip is snapped into the first positioning groove; when the locking rod is rotated downward to a vertical direction, the elastic clip is snapped into the second positioning groove; thereby realizing the snap-in limiting of the two states of the locking rod.

[0017] Optionally, a water storage chamber is provided in the middle of the locking rod, a connector connected to the water storage chamber and for connecting to an external water pipe is fixedly provided on the outer periphery of the locking rod, and a plurality of water spray outlets connected to the water storage chamber are provided on the side of the locking rod away from the main body.

[0018] By adopting the above technical solution, when the soundproof screen is installed at the construction site and dust prevention treatment is required, due to the coordinated arrangement of the water storage chamber, the connecting head and the water spraying port, the staff can install the external water pipe on the connecting head, inject water into the water storage chamber and spray it out from the water spraying port to reduce dust.

[0019] Optionally, a collecting chamber is vertically provided inside the main body, a dust suction port connected to the collecting chamber is provided on the upper portion of the main body, and a dust suction fan is embedded on the inner wall of the dust suction port; a discharge port connected to the collecting chamber is provided on the side wall of the clearance gap, a rotating sleeve inserted into the discharge port is fixedly provided on the two side walls opposite to the clearance gap, and a rotating through hole for inserting the rotating sleeve is provided on the moving block; a storage chamber connected to the rotating through hole is provided on the side of the moving block facing the moving wheel, and a storage member is provided in the storage chamber, and the storage member is used to store dust that passes through the dust suction port, the collecting chamber and the rotating sleeve in sequence.

[0020] By adopting the above technical solution, when the sound insulation screen is installed at the construction site and dust prevention treatment is required, due to the coordinated arrangement of the dust suction fan, the rotating sleeve and the storage part, the staff can start the dust suction fan, inject the dust into the storage chamber through the dust suction port, the collection chamber and the rotating sleeve to be collected by the storage part, and finally take the storage part out of the storage chamber to centrally treat the dust or other impurities.

[0021] Optionally, the storage piece is a storage drawer inserted into the storage cavity, and a storage through hole that can overlap with the rotating through hole is provided on the outer surface of the storage drawer; an elastic plug-in piece is provided on the outer surface of the storage drawer, and a locking groove for the elastic plug-in piece to be inserted into is provided on the side wall of the storage cavity.

[0022] By adopting the above technical solution, when the storage piece is used, the storage drawer is inserted into the storage cavity in the moving block, so that the elastic connector is inserted into the corresponding locking groove, and at the same time the storage through hole coincides with the rotating through hole, so that the dust in the collection cavity can be injected into the storage drawer through the storage through hole.

[0023] Optionally, a traction handle is fixedly provided on the side of the storage drawer away from the moving block.

[0024] By adopting the above technical solution, when the storage drawer needs to be pulled out, due to the installation arrangement of the traction handle, the user applies force to the traction handle to make the elastic connector disengage from the locking groove, and then pull out the storage drawer, thereby improving the performance of the storage drawer when pulling it out.

[0025] Optionally, the supporting hole is a waist-shaped through hole.

[0026] By adopting the above technical solution, due to the opening of the waist-shaped through hole, it is convenient for the staff to use bolts to penetrate the supporting holes on the supporting plate to fix the sound insulation screen on the installation surface, which is more convenient.
