Description

Technical Field

[0001] The invention relates to a water curtain device for bridge deck dust reduction and landscaping. Background Art

[0002] As part of the city beautification, combined with local culture and natural conditions, lights, water curtains and their combination can form landscapes and enhance the city's appearance. The bridge is close to the river and water, and it is more suitable for light demonstrations combined with water curtains. For example, the Chinese patent with patent number CN201922371979.4 discloses a one-dimensional CNC water curtain device for bridges, which forms landscapes through the combination of lights and water curtains. The disadvantage is that the nozzles of existing water curtain devices are usually only used to cooperate with lights to form water curtain landscapes, which only have cultural and ornamental value but not practical performance. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the present invention is to provide a water curtain device for bridge deck dust reduction and landscaping, which can not only meet the function of night water curtain light show, but also can spray on the bridge deck to reduce dust or prevent dust during the demonstration period.

[0004] Bridges are usually important transportation hubs connecting the two sides of rivers. They have a large volume of traffic and are prone to dust in dry weather, so watering vehicles and spray dust removal vehicles are needed to operate. The water curtain is formed by the water column sprayed from the nozzle. Since there are many vehicles on the bridge road, spraying water directly on the road surface will hinder passing vehicles and even cause traffic accidents. In addition, although spraying water directly on the road surface can wet the ground to prevent dust, it cannot reduce dust. If an atomizing nozzle is used, the water curtain required for the light show cannot be formed.

[0005] To this end, the present invention provides a water curtain device for both dust reduction and landscaping on a bridge deck, comprising a nozzle, the nozzle comprising an adjustment unit, the nozzle is adjusted by rotating the adjustment unit, and the device also comprises a rack, the outer wall of the adjustment unit is provided with a gear, the gear cooperates with the rack, the nozzle can be rotated so that the nozzle faces one side of the center of the bridge deck or a target position for forming a water curtain, and when the nozzle rotates, the gear and rack cooperate to adjust the nozzle to a corresponding flow rate.

[0006] Furthermore, the nozzle is connected to a rotating seat, and the rotating seat rotates along a rotating shaft when driven by a motor.

[0007] Furthermore, the length of the rack is adjustable.

[0008] Furthermore, a groove is provided under at least part of the teeth of the rack, a pad is provided in the groove, and the teeth are fixed on the pad. By removing the pad, the corresponding teeth are moved down into the groove so that the corresponding teeth are not engaged with the gear.

[0009] Furthermore, it also includes a limit block, which is used to limit the rotation angle of the nozzle.

[0010] Furthermore, the rack also includes a base, the width of the base is greater than the width of the rack, and the limit stopper can be moved along the base to the target area and then fixed on the base.

[0011] Furthermore, the nozzle also includes an inner core and a flow channel, the adjusting unit is provided with an internal thread, the inner core is provided with an external thread, the inner core has a tapered end and a stepped inner core body, the adjusting unit is provided with an inner cavity, the shape of the inner cavity matches the tapered end and the stepped inner core body, and when the adjusting unit rotates relative to the inner core, the adjusting flow channel is used to adjust the nozzle.

[0012] The beneficial effects of the present invention are:

[0013] (1) The nozzle of the multifunctional light show water curtain device of the present invention can rotate. When a water curtain is formed, the nozzle faces the target position. When dust reduction is required, the nozzle faces the side of the bridge deck. The nozzle can adjust the flow rate through the regulating unit, so that the nozzle can switch between water spraying and spraying functions. The outer wall of the regulating unit is provided with a gear, and the gear cooperates with the rack fixed on the bracket. When the nozzle faces the outside of the bridge, the regulating unit rotates to a larger flow rate to spray water to form a light show water curtain. When the nozzle turns to the bridge deck, the gear and rack of the regulating unit cooperate to make the nozzle spray, thereby realizing the conversion between the bridge deck dust reduction and light show water curtain functions.

[0014] (2) At least part of the teeth on the rack of the present invention are adjustable, and a pad is provided under the teeth. The pad is fixed to the rack base by bolts. By removing the pad, the teeth are moved down into the groove. The essence of this is to increase or shorten the length of the rack, so that the stroke of the gear on the nozzle can be changed during debugging, so that when the adjustment unit rotates around the rack, the nozzle can be adjusted to a suitable range.

DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] Reference Figures 1 to 4 As shown, a water curtain device for bridge deck dust reduction and landscaping of the present invention comprises a nozzle 3, the nozzle 3 comprises an adjusting unit 301, a gear 302 is provided on the outer wall of the adjusting unit 301, the gear 302 drives the adjusting unit 301 to rotate to adjust the nozzle 3, the rack 2 is fixed on the fixing plate 1 of the bracket, the gear 302 cooperates with the rack 2, the nozzle 3 is connected to the rotating seat 4, and the rotating seat 4 drives the nozzle 3 to rotate under the drive of the motor 5 so that the nozzle 3 faces the center side of the bridge deck or the target position for forming a light show water curtain. Its working principle is as follows: when the nozzle 3 rotates driven by the rotating seat 4, the gear 302 engages with the rack 2 so that the adjustment unit 301 rotates driven by the rotating seat 4 while also rotating with itself as the axis relative to the inner core 303 of the nozzle 3. Through pre-design, when the nozzle 3 rotates toward the target position, the flow channel 304 becomes larger. When it rotates to the target position, the nozzle 3 can spray out a suitable water column to form a water curtain. When the nozzle 3 rotates in the opposite direction, the gear 302 and the rack 2 cooperate to adjust the nozzle 3 to narrow the flow channel 304. When the nozzle 3 rotates to a position facing the bridge deck, the nozzle 3 can atomize the water flow to form a spray.

[0022] In the above embodiment, referring to Figure 1 and Figure 2 As shown, the motor 5 is arranged in the chassis 6, and a gear speed change mechanism is also provided in the chassis 6. The motor shaft is connected to the gear speed change mechanism. The gear speed change mechanism is used to reduce the rotation speed. The higher rotation speed of the motor is converted into a lower rotation speed output through the engagement of the small gear and the large gear. The gear speed change mechanism is connected to the rotating arm 7. One end of the rotating arm 7 is hinged on the rotating seat 4. The lower end of the rotating seat 4 is connected to the chassis 6 and the fixed plate 1 through a rotating shaft. The chassis 6 and the fixed plate 1 can be fixed on the bridge guardrail. In some other embodiments, the chassis 6 and the fixed plate 1 can be fixed on a bracket, and the bracket has a certain height from the bridge surface.

[0023] In the above embodiment, referring to Figure 3As shown, the length of the rack 2 is adjustable, the rack 2 is arranged on the base 201, and a groove 202 is provided under at least part of the teeth 203. The lower ends of the groove 202 and the teeth 203 are provided with a limit block 204 for preventing the teeth 203 from coming out. A cushion block 205 is provided in the groove 202, and protruding wing plates can be provided at both ends of the teeth 203. The wing plates and the cushion blocks 205 are fixed to the base 201 by bolts. In the above embodiment, although the stroke of the gear 302 can be limited by the preset length of the rack 2, the number of rotations of the adjustment unit 301 can be controlled by the stroke of the gear 302, and the meshing action of the rack 2 and the gear 302 is used to automatically adjust the adjustment unit 301 to the preset position. The position of the nozzle 3 makes the nozzle 3 form the required water curtain or spray, but in actual engineering, the nozzle 3 still needs to be further debugged and adjusted accordingly after installation to form a better effect with the lights on the bridge. In the above embodiment, after the rack 2 is installed, the adjustment is more difficult and complicated. In this embodiment, by setting a rack 2 longer than expected, when debugging the light show equipment, the pad 205 can be added to make the bar teeth 203 work, or the pad 205 can be removed to make the corresponding bar teeth 203 not work, thereby changing the corresponding stroke of the adjustment unit 301 on the nozzle 3, so that the nozzle 3 that reaches the predetermined position can be properly adjusted to a suitable state.

[0024] In the above embodiment, referring to Figure 1 and Figure 3 As shown, it also includes a limit stopper 8, which is installed at the target position, including the position reached by the nozzle 3 forming the light show water curtain and the position for spraying the bridge deck. The target position can be set outside the range of the rack 2. In this embodiment, Figure 1 A fixed limit stopper 8 is shown, which is set at the target position of the nozzle 3 of the light show water curtain, and an adjustable limit stopper 8 is set on the other side. The width of the base 201 is greater than the width of the rack 2. The adjustable limit stopper 8 can be adjusted to the target area along the base 201 and fixed to the base 201 by bolts. During debugging, the direction of the nozzle 3 can be adjusted by resetting the position of the limit stopper 8. The adjustable limit stopper 8 of this embodiment actually limits the stroke of the gear 302 and also has the function of adjusting the spray size of the nozzle 3.

[0025] In the above embodiment, referring to Figure 4As shown, the nozzle 3 also includes an inner core 303 and a flow channel 304, the adjustment unit 301 is provided with an internal thread, the inner core 303 is provided with an external thread, the inner core 303 has a tapered end and a stepped inner core 303 body, the adjustment unit 301 is provided with an inner cavity, the shape of the inner cavity matches the tapered end and the stepped inner core 303 body, when the adjustment unit 301 rotates relative to the inner core 303, the adjustment flow channel 304 is used to adjust the nozzle 3, and an interface is provided between the lower end of the nozzle and the water pipe, and the water pipe is usually also connected to a pump. The nozzle 3 of the present invention can also adopt other nozzle 3 structures in the prior art, and the specific structure inside the nozzle 3 does not affect the present invention.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
