Abstract
Description
Technical Field
[0001] The invention relates to the technical field of road facilities cleaning, in particular to an automatic cleaning device for a highway sound insulation screen. Background Art
[0002] A sound barrier is a soundproof facility. In order to block the direct sound between the sound source and the receiver, a facility is inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. In daily use of roads and railways, vehicles will generate huge noise during operation for a long time. As the scope of roads and railways is becoming wider and wider, the probability of passing through residential areas is also increasing. Therefore, in order to reduce the impact of road noise on residents, it is necessary to set up sound barriers on both sides of the road.
[0003] The sound barrier uses a plate-shaped guardrail structure with different sound insulation principles, such as using its own material to isolate the propagation of sound; or setting a large number of meshes on the surface to achieve the purpose of noise reduction by refracting and dissipating sound waves; in addition, there are vacuum glass-type sound barriers, which use the loss of sound waves passing through different media through an artificially set vacuum layer to reduce noise. When vehicles pass through the road, dust will inevitably be generated and attached to the sound barrier, resulting in a weakened noise reduction effect of the sound barrier, so the sound barrier needs to be cleaned regularly.
[0004] At present, the cleaning of barriers on both sides of the road mainly relies on regular cleaning by cleaning vehicles, which is inefficient, cumbersome, and will affect the normal use of the road. Therefore, there are some structural designs that can be automatically cleaned for noise barriers, but the automatic cleaning equipment cannot achieve the cleaning effect by only using water flushing. If a brush that can move on the surface of the noise barrier is set, dust will remain on the surface after the brush has been used for a certain period of time. In subsequent use, not only will the cleaning effect not be achieved, but the dust may be evenly spread on the surface of the noise barrier, causing more serious dirt; at the same time, the brush attached to the surface of the noise barrier is difficult to clean, and manual maintenance is also very difficult.

DETAILED DESCRIPTION
[0033] 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.
[0034] See also Figures 1 to 9 In an embodiment of the present invention, an automatic cleaning device for a highway sound insulation screen comprises a sound insulation board 1 and a frame structure 2; symmetrical side frames 22 are respectively installed on both sides of the sound insulation board 1, and the two ends of the side frames 22 are respectively connected by a top frame 21 and a bottom frame 23; a cleaning structure 5 is installed on the surface of the sound insulation board 1, and the cleaning structure 5 comprises a rotating shaft 52 connecting the two side frames 22, and two opposite wiper strips 51 are installed on the rotating shaft 52; a primary ratchet structure 7 is installed at both ends of the rotating shaft 52, and the primary ratchet structure 7 is connected to a transmission gear 53 sleeved on the rotating shaft 52; a slider 55 is connected to both ends of the rotating shaft 52 through a secondary ratchet structure 8, and the slider 55 is slidably installed inside the side frames 22; a rack 54 is installed at both ends of the side frames 22, and the rack 54 is located on the moving track of the transmission gear 53 and meshes with the transmission gear 53, and the number of teeth of the transmission gear 53 is four times the number of teeth of the rack 54;
[0035] A dirt cleaning structure 4 is installed in the bottom frame 23, and the dirt cleaning structure 4 is used to clean the dirt on the wiper strip 51;
[0036] A lifting structure 6 is installed in the side frame 22, and the lifting structure 6 is connected to the slider 55. The lifting structure 6 is used to drive the slider 55 to move up and down;
[0037] The primary ratchet structure 7 is used to limit the transmission gear 53 to drive the rotating shaft 52 to rotate in only one direction; the secondary ratchet structure 8 is used to limit the rotating shaft 52 to rotate in only one direction;
[0038] A water collecting structure 3 is installed on the top frame 21 , and the water collecting structure 3 is used to collect rainwater and spray water onto the surface of the sound insulation board 1 .
[0039] The sound insulation board 1 is not a necessary structure in the present device, but is only used as a reference structure for positioning the installation positions of other parts of the structure. The present device uses rainwater or other water collected by the water collection structure 3 to clean the sound insulation board 1. The rotating shaft 52 can move on the surface of the sound insulation board 1, and two wiper strips 51 separated from each other are installed on the rotating shaft 52 to clean the surface of the sound insulation board 1. The wiper strips 51 are not restrictive structures. According to the different surface materials of the sound insulation board 1, the use of other types of strip brushes also meets the requirements of the present device.
[0040] In the initial state, the wiper strips 51 on both sides of the rotating shaft 52 are located in the same plane, one of which is attached to the sound insulation board 1, and the lifting structure 6 drives the rotating shaft 52 to move downward through the slider 55. The wiper strips 51 continuously scrape dust and dirt on the surface of the sound insulation board 1 with the assistance of water flow until the rotating shaft 52 reaches the bottom frame 23.
[0041] The device is provided with a secondary ratchet structure 8 between the slider 55 and the rotating shaft 52. Under the action of the secondary ratchet structure 8, the rotating shaft 52 can only rotate in one direction, that is, the side close to the sound insulation board 1 moves downward. At the same time, a primary ratchet structure 7 is also installed on the rotating shaft 52. Under the action of the primary ratchet structure 7, the rotation of the transmission gear 53 can be transmitted to the rotating shaft 52, driving the rotating shaft 52 to rotate. When the driving direction received by the transmission gear 53 is opposite to the direction allowed to rotate by the rotating shaft 52, the characteristics of the ratchet can be used to avoid the transmission gear 53 and the rotating shaft 52 from conflicting.
[0042] In this device, racks 54 are provided at both ends of the side frame 22. The top rack 54 is located on the side of the transmission gear 53 close to the sound insulation board 1, and the bottom rack 54 is located on the side of the transmission gear 53 away from the sound insulation board 1. Therefore, as the slider 55 drives the rotating shaft 52 to move downward, the transmission gear 53 will pass through the bottom rack 54. Since the number of teeth of the rack 54 is one-fourth of the number of teeth of the transmission gear 53, the rack 54 can drive the transmission gear 53 and the rotating shaft 52 to rotate ninety degrees, that is, the wiper strip 51 originally used to scrape dust rotates to the bottom and contacts the cleaning structure 4 at the bottom, which can remove stains on the surface of the wiper strip 51 and achieve self-cleaning. Due to the continuous downward flow of water from the top, the water enters the interior of the bottom frame 23, so that the wiper strip 51 and the cleaning structure 4 at the bottom are immersed in water, so that the wiper strip 51 can be quickly restored to cleanliness by simple scrubbing.
[0043] After cleaning the wiper strip 51, the rotating shaft 52 is raised again. Due to the cooperation of the primary ratchet structure 7 and the secondary ratchet structure 8, the rotation of the transmission gear 53 caused by the limit of the rack 54 at this time will not be transmitted to the rotating shaft 52. Therefore, during the lifting of the rotating shaft 52, the wiper strip 51 is in the vertical plane and does not contact the sound insulation board 1. After reaching the top, it is affected by the top rack 54 again. The clean wiper strip 51 originally located on the outside reaches the inside after a 180-degree rotation and can be used for the next round of wiping.
[0044] The device can utilize the wiper strip 51 and clean water to realize self-cleaning of the sound insulation board 1, and can be used continuously without manual operation or external equipment, thereby ensuring the sound insulation effect of the sound insulation board 1 and reducing the impact of road noise on surrounding residents.
[0045] As another embodiment of the present invention, please refer to Figure 1 , Figure 6and Figure 7 The cleaning structure 4 includes a sliding plate 42 installed in the bottom frame 23, and a brush 41 is installed on the sliding plate 42. The position of the brush 41 corresponds to the position of the rotating shaft 52. The sliding plate 42 can drive the brush 41 to slide left and right. When the wiper strip 51 drops to the bottom, it presses on the brush 41. The rapid sliding of the brush 41 can remove the dust on the surface of the wiper strip 51, so that the wiper strip 51 is kept clean. Since the brush 41 is immersed in water, the dust brushed out will not stick to the brush 41 in large quantities, but will be gradually discharged with the overflow of water in the bottom frame 23 or artificial drainage.
[0046] See also Figure 7 , a protruding adjustment frame 232 is installed on the bottom frame 23, a limit frame 421 inserted into the adjustment frame 232 is installed on the sliding plate 42, a primary motor 43 is installed in the adjustment frame 232, the primary motor 43 is connected to an eccentric wheel 44, and the eccentric wheel 44 is located in the limit frame 421. The adjustment frame 232 is used to install the structure of adjusting the sliding plate 42, and the primary motor 43 drives the eccentric wheel 44 to rotate, thereby pushing the limit frame 421 to slide left and right, driving the sliding plate 42 to slide. The above structure is not a restrictive structure. In addition to using the eccentric wheel 44, using a structure that can move back and forth, such as a screw rod, a scissor structure, or directly using an electric push rod to push and pull repeatedly, can meet the structural requirements of the device. Considering that it can be installed in a small space and is not easily affected by dust and water, the device preferably uses the eccentric wheel 44 to drive.
[0047] See also Figure 3 and Figure 5 The lifting structure 6 includes a sling 61 and a slide bar 66. A slide groove 221 is provided in the side frame 22. A slide bar 66 is installed in the slide groove 221. The sling 61 is a closed loop structure. The slider 55 is sleeved on the slide bar 66. The sling 61 is connected to the slider 55. A positioning wheel 62 is installed in the bottom frame 23. The sling 61 bypasses the positioning wheel 62. The lifting structure 6 uses the sling 61 to control the lifting and lowering of the slider 55. The slide bar 66 is used to limit the moving track of the slider 55 to ensure that the wiper strip 51 can fit on the surface of the sound insulation board 1 when it descends. The positioning wheel 62 at the bottom is used to limit the moving track of the sling 61.
[0048] See also Figure 5, a secondary motor 65 is installed in the top frame 21, the secondary motor 65 is connected to the driving wheel 63, the sling 61 passes around the driving wheel 63, and a plurality of auxiliary wheels 64 surrounding the driving wheel 63 are installed in the top frame 21, and the auxiliary wheels 64 are in pressure contact with the sling 61. The sling 61 is pressed between the driving wheel 63 and the auxiliary wheels 64, so a certain resistance can be generated between the driving wheel 63, and the secondary motor 65 drives the driving wheel 63 to rotate, so as to realize the control of the sling 61. The above structure is not a restrictive structure. In addition to using the sling 61 to control the slider 55, the slide bar 66 can also be directly replaced by a screw-like structure to control the lifting of the slider 55. However, considering that the device is used for cleaning the sound insulation board 1, the structures of each part cannot avoid contact with moisture. Therefore, in order to reduce the impact caused by rust, the use of the sling 61 has a more stable effect.
[0049] See also Figure 3 , Figure 8 and Fig. 9 The primary ratchet structure 7 includes a primary ratchet ring 73 and a primary turntable 74. The primary ratchet ring 73 is fixedly arranged inside the transmission gear 53. The primary turntable 74 is fixedly mounted on the rotating shaft 52. A primary ratchet 71 is rotatably mounted on one side of the primary turntable 74. A primary spring 72 is connected between the primary ratchet 71 and the primary turntable 74. The primary ratchet 71 is inserted into the tooth groove of the primary ratchet ring 73. The primary turntable 74 is located inside the primary ratchet ring 73. The primary ratchet 71 is stuck in the tooth groove under the action of the primary spring 72. Since the rotation direction of the rotating shaft 52 itself is limited, when the rotation generated by the transmission gear 53 is consistent with the direction in which the rotating shaft 52 can rotate, the primary ratchet ring 73 can drive the stuck ratchet, and then drive the rotating shaft 52 to rotate together. When the rotation direction of the transmission gear 53 is in the opposite direction, the rotating shaft 52 cannot rotate. At this time, the primary ratchet ring 73 will rotate around the primary turntable 74.
[0050] See also Figure 3 , Figure 8 and Fig. 9 The secondary ratchet structure 8 includes a secondary ratchet ring 81 and a secondary rotating disk 83. The secondary rotating disk 83 is fixedly connected to the rotating shaft 52. The secondary ratchet ring 81 is fixedly connected to the slider 55. The secondary rotating disk 83 is located inside the secondary ratchet ring 81. The secondary rotating disk 83 is connected with a secondary ratchet tooth 82 through a secondary spring 84. The secondary ratchet tooth 82 is inserted into the tooth groove of the secondary ratchet ring 81. The position of the secondary ratchet ring 81 is fixed and cannot rotate. When the inner side of the rotating shaft 52 rotates downward, the secondary ratchet tooth 82 does not conflict with the secondary ratchet ring 81 and can rotate. When the rotating shaft 52 rotates in the opposite direction, it is restricted and cannot rotate. Therefore, when wiping downward, the wiper strip 51 can be kept always moving by friction with the surface of the sound insulation board 1, and will not rotate under the action of friction.
[0051] See also Figure 8 and Fig. 9 The rotating shaft 52 is sleeved with a limiting cylinder 56, and the limiting cylinder 56 is fixedly connected to the slider 55. The position of the limiting cylinder 56 is fixed, and the two ends of the rotating shaft 52 are inserted into the limiting cylinder 56, which can obtain more support, improve its own stability, and avoid transmitting all the torque to the connection of the secondary ratchet structure 8.
[0052] See also Figure 1 and Figure 2 The water collection structure 3 includes a water tank 31, which is mounted on the top frame 21. A water pump 33 is mounted on the water tank 31. A plurality of water outlet pipes 211 connected to the water tank 31 are opened on the top frame 21. The water outlet pipes 211 are tilted toward the sound insulation board 1. Photovoltaic panels 32 tilted toward the inside of the water tank 31 are mounted on both sides of the water tank 31. A storage battery 34 is mounted on one side of the bottom frame 23. The water tank 31 is used to collect rainwater. The photovoltaic panels 32 on the top convert the sunlight on sunny days into electricity and store it in the storage battery 34, which can be used to drive the primary motor 43, the secondary motor 65 and the water pump 33 during cleaning. The water outlet pipe 211 is tilted toward the side of the sound insulation board 1 so that the discharged rainwater can be flushed on the sound insulation board 1 for cleaning the sound insulation board 1. In addition, a water pump 33 is also mounted on the water tank 31. In an environment with little rain, the sound insulation board 1 can be automatically cleaned by external water supply.
[0053] See also Figures 1 to 3 A connecting frame 24 is installed at one end of the bottom frame 23 away from the top frame 21. A plurality of mounting holes 241 are provided on the connecting frame 24, and a water outlet 231 is provided on one side of the bottom frame 23. The mounting holes 241 on the connecting frame 24 are used to cooperate with tools such as nails to fix the connecting frame 24 on a support, guardrail or cement board at a specified position. Depending on different installation environments, connecting frames 24 of different shapes can be used. The water outlet 231 on the bottom frame 23 is used to discharge sewage in the bottom frame 23 during regular maintenance by personnel to avoid too much dust accumulation in the bottom frame 23. Compared with cleaning a brush or a wiper strip 51 pressed on the surface of the sound insulation board 1, cleaning the bottom frame 23 is much easier and easier to clean, so the difficulty of manual maintenance can be significantly reduced.
[0054] The working principle of the present invention is:
[0055] The device is provided with a frame structure 2 consisting of a top frame 21, a bottom frame 23 and a side frame 22 around the sound insulation board 1. A rotating shaft 52 is installed on the surface of the sound insulation board 1. A symmetrically fixed wiper strip 51 is installed on the rotating shaft 52. Both ends of the rotating shaft 52 are connected to a slider 55 through a secondary ratchet structure 8. The slider 55 can be lifted and lowered under the action of a lifting structure 6. A transmission gear 53 is also installed on the rotating shaft 52. One-way transmission is performed between the transmission gear 53 and the rotating shaft 52. Racks 54 are installed on the top and bottom of the side frame 22. The number of teeth of the rack 54 is one-fourth of the number of teeth of the transmission gear 53. Whenever the rotating shaft 52 reaches the top or bottom of the sound insulation board 1, it will rotate 90 degrees under the action of the rack 54. The device cooperates with the rainwater on the top to wash the sound insulation board 1. The wiper strip 51 scrapes the dust on the surface of the sound insulation board 1 during the descending process of the rotating shaft 52. After reaching the bottom, the wiper strip 51 with dust on it rotates 90 degrees to point downward and is cleaned by the cleaning structure 4. Then the rotating shaft 52 is raised to the top, and the wiper strip 51 rotates 90 degrees again to contact the sound insulation board 1 for the next round of cleaning. The device is flexible and convenient to use. It can continuously and automatically clean the sound insulation board 1 without the assistance of external equipment, keep the sound insulation board 1 clean, avoid the problem of weakened sound insulation effect of the sound insulation board 1, and ensure the quality of life of surrounding residents.
