[0003] During municipal construction, a lot of dust is easily generated on the construction site. When vehicles pass by nearby, a lot of dust will be raised, causing pollution to the environment. It is generally necessary to manually drive a sprinkler truck to regularly sprinkle water on the road surface to achieve the purpose of dust reduction. However, this method cannot be used frequently and is time-consuming and labor-intensive, and needs to be improved. Summary of the invention

[0004] The purpose of the present application is to provide a road protection guardrail and a method of using the same, in order to solve the problem that existing dust reduction methods are relatively time-consuming and labor-intensive.

[0005] First aspect

[0006] The road protection guardrail provided in this application adopts the following technical solution:

[0007] A road protection guardrail comprises a guardrail body, the guardrail body is provided with a water storage frame, the water storage frame is provided with a hollow cavity, the guardrail body is provided with a dust reduction spray device, the top of the water storage frame is provided with a water collecting trough, the bottom of the water collecting trough is provided with a water injection port connected with the hollow cavity, the water storage frame is provided with a conveying device for conveying water from the hollow cavity to the dust reduction spray device, the water storage frame is provided with a water inlet pipe connected with the hollow cavity, and the water inlet pipe is provided with an opening and closing member for controlling the interruption of water flow.

[0008] By adopting the above technical scheme, the first situation is artificial water collection, which is to open the water inlet pipe by controlling the opening and closing parts, and inject water into the hollow cavity from one end of the water inlet pipe through an external water pipe, so that water can enter the hollow cavity; the second situation is water collection on rainy days, rainwater falls into the water collection tank and enters the water injection port, and rainwater enters the hollow cavity through the water injection port; the two water collection methods can be selected according to the situation, which improves the convenience of water collection.

[0009] The conveying device conveys the water in the hollow cavity to the dust reduction spray device, and the dust reduction spray device sprays water outwardly. The water absorbs the dust in the air to reduce the dust, thereby achieving the effect of dust reduction and reducing the pollution to the environment. In addition, water is sprayed through the guardrail to reduce dust, and dust can be reduced in multiple locations at the same time, and the coverage area is also wider. Compared with the situation of frequently and regularly sprinkling water on the road surface by manually driving a sprinkler truck, this solution is more time-saving and labor-saving.

[0010] Optionally, the water storage frame is rotatably provided with a cover plate, the cover plate is used to cover the water inlet, and the water storage frame is provided with a first reset member for driving the cover plate to reset after rotation.

[0011] By adopting the above technical solution, on non-rainy days, under the action of the first reset member, the cover plate covers the water inlet, which can reduce the entry of external dust into the hollow cavity and play a role in dust prevention. At the same time, on rainy days, rainwater falls into the water collection tank to form accumulated water. When the accumulated water reaches a certain amount, it can drive the cover plate to rotate and open the water inlet. At this time, the first reset member is subjected to force to produce elastic deformation, and the first reset member maintains a tendency to reset elastically. When the accumulated water decreases, the first reset member promptly drives the cover plate to reset so that the cover plate can cover the water inlet.

[0012] Optionally, the opening and closing member is an opening and closing cover slidably arranged on the water inlet pipe, the opening and closing cover is provided with a groove for one end of the water inlet pipe to be inserted into, the groove wall of the groove is provided with a water-blocking pad, and the opening and closing cover and the water inlet pipe are provided with a tightening structure that drives the opening and closing cover to slide toward the water inlet pipe.

[0013] By adopting the above technical solution, the tightening structure drives the opening and closing cover to slide along the length direction of the water inlet pipe toward the water inlet pipe, one end of the water inlet pipe is embedded in the groove and tightened against the water blocking pad under the action of the tightening structure, thereby achieving the closure of the water inlet pipe; the water blocking pad has a waterproof effect.

[0014] By applying force, the opening and closing cover is driven to slide along the length direction of the water inlet pipe in a direction away from the water inlet pipe, and the water inlet pipe is moved out of the embedded groove, so that it can be easily connected with an external water pipe to realize water injection into the hollow cavity.

[0015] Optionally, the clamping structure includes a guide block arranged on the circumferential side wall of the water inlet pipe, a guide groove arranged on the opening and closing cover and cooperating with the guide block, and a first elastic member arranged in the guide groove, wherein the first elastic member is used to drive the opening and closing cover to slide toward the water inlet pipe, the water inlet pipe is provided with a first arc groove, and the opening and closing cover is provided with a second arc groove corresponding to the first arc groove.

[0016] By adopting the above technical solution, the guide block is inserted into and slides in the guide groove, which guides and limits the sliding of the opening and closing cover. When the opening and closing cover slides along the length direction of the water inlet pipe in the direction away from the water inlet pipe, the first elastic member is subjected to force to produce elastic deformation, and the first elastic member maintains a tendency to elastically return to its original position.

[0017] The first arc groove and the second arc groove are spliced ​​to form a circular hole for the external water pipe to pass through, and under the action of the elastic restoring force of the first elastic member, the external water pipe is clamped between the opposite groove walls of the first arc groove and the second arc groove, thereby fixing the external water pipe and facilitating water injection.

[0018] Optionally, the conveying device includes a water outlet pipe arranged on the water storage rack and connected to the hollow cavity, an electric valve arranged on the water storage rack and used to control the water flow of the water outlet pipe, and a water pump arranged on the water storage rack and connected to the water outlet pipe.

[0019] By adopting the above technical solution, the electric valve is opened, and the water pump is started. The water pump draws water out of the hollow cavity from the water outlet pipe and transports it to the dust suppression spray device.

[0020] Optionally, the dust suppression spray device includes a transition pipe arranged on the guardrail body and a plurality of nozzles arranged on the transition pipe, and the transition pipe is connected to the water pump via a connecting pipe.

[0021] By adopting the above technical solution, the water pump injects water into the transition pipe, and the water is then sprayed out from the nozzle through the transition pipe.

[0022] Optionally, a sliding block and a stopper are slidingly provided on the inner wall of the hollow cavity, the sliding block is provided with a buoyancy ball, the sliding block and the stopper are connected with each other via a first connecting rope, and the stopper is used to cover one end of the water inlet pipe.

[0023] By adopting the above technical solution, there is no need to spray dust through the dust reduction spray device on rainy days, so the water in the hollow cavity will continue to increase. The water level continues to rise and acts on the float, driving the float to rise, and the float drives the sliding block to slide. The sliding block drives the block to slide through the first connecting rope, so that the block originally covering one end of the water inlet pipe is misaligned with the water inlet pipe, so that the water in the hollow cavity can enter the water inlet pipe. Under the action of the water pressure of continuous water injection, the opening and closing cover is driven to slide along the length direction of the water inlet pipe in the direction away from the water inlet pipe, so that the water in the hollow cavity can be discharged through the water inlet pipe.

[0024] At the same time, the inner wall of the hollow cavity can be flushed and cleaned, and the sediment or stains attached to the inner wall of the hollow cavity can be removed.

[0025] Optionally, a water blocking plate for covering one end of the water outlet pipe is slidably provided on the inner wall of the hollow cavity, the water blocking plate is connected to the block via a second connecting rope, and a second elastic member is provided at one end of the water blocking plate away from the second connecting rope.

[0026] By adopting the above technical solution, when the block slides, the second connecting rope drives the water blocking plate to slide, and the water blocking plate covers one end of the water outlet pipe, which can reduce the sediment or stains in the hollow cavity from entering the water outlet pipe and affecting the normal operation of the electric valve and the water pump. At the same time, the second elastic member is subjected to elastic deformation and maintains a tendency to elastically return to its original position.

[0027] When the rain stops, the water level in the hollow cavity gradually drops, the second elastic member resets to drive the water blocking plate and one end of the outlet pipe to gradually misalign, the baffle is driven by the second connecting rope to gradually cover one end of the inlet pipe, and the sliding block is reset by the first connecting rope.

[0028] Optionally, the block is provided with a through groove corresponding to the water inlet pipe, the block is rotatably provided with a baffle for covering the through groove, the block is provided with a second reset member for driving the baffle to reset after rotation, and the baffle sleeve is provided with a water blocking ring.

[0029] By adopting the above technical solution, water is injected into the hollow cavity from the water inlet pipe through an external water pipe. Under the action of water pressure, the baffle rotates to allow water to enter the hollow cavity for injection; the water-blocking ring has a waterproof effect.

[0030] Second aspect

[0031] The present application provides a method for using a road protection guardrail, including the following contents:

[0032] Artificial water collection, by controlling the opening and closing parts to open the water inlet pipe, water is injected into the hollow cavity from one end of the water inlet pipe, and at the same time, when the water passes through the groove, the baffle is driven to rotate, so that the water can enter the hollow cavity;

[0033] When it rains, the rainwater falls into the water collection tank to form accumulated water. When the accumulated water reaches a certain amount, it can drive the cover plate to rotate to open the water injection port, and the rainwater enters the hollow cavity through the water injection port;

[0034] Cleaning of the hollow cavity: During the water collection process on rainy days, when the water level in the hollow cavity rises and the sliding block is driven to slide by the buoyancy ball, the block is misaligned with the water inlet pipe. Under the action of water pressure, the opening and closing member opens the water inlet pipe, and the water in the hollow cavity flows out from the water inlet pipe. At the same time, rainwater continues to enter the water inlet, which can wash the inner wall of the hollow cavity.

[0035] Dust reduction spraying is done by starting the electric valve to open the water outlet pipe and starting the water pump. The water pump transports the water in the hollow cavity to the transition pipe. The water in the transition pipe is then sprayed out from several nozzles. The water absorbs the dust in the air to reduce the dust.

[0036] By adopting the above technical scheme, the conveying device conveys the water in the hollow cavity to the dust reduction spraying device, and the dust reduction spraying device sprays water outwardly. The water absorbs the dust in the air to reduce the dust, thereby achieving the effect of dust reduction and reducing the pollution to the environment. In addition, by spraying water to reduce dust through guardrails, dust can be reduced in multiple locations at the same time, and the coverage area is also wider. Compared with the situation of frequently and regularly sprinkling water on the road surface by manually driving a sprinkler truck, this solution is more time-saving and labor-saving.

[0037] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] 1. The conveying device conveys the water in the hollow cavity to the dust suppression spraying device, which sprays water to the outside, and the water absorbs the dust in the air to reduce the dust, thereby achieving the effect of dust reduction and reducing the pollution to the environment. In addition, the dust can be reduced at multiple locations at the same time by spraying water through the guardrail, and the coverage area is also wider. Compared with the situation of regularly spraying water on the road surface by manually driving a sprinkler truck, this solution is more time-saving and labor-saving;

When the accumulated water reaches a certain amount, the cover plate (24) can be driven to rotate to open the water injection port (23), and the rainwater enters the hollow cavity (21) through the water injection port (23); Cleaning of the hollow cavity (21), during the water collection process on rainy days, when the water level in the hollow cavity (21) rises and the sliding block (8) is driven to slide by the buoyancy ball (81), the stopper (9) and the water inlet pipe (5) are misaligned, and under the action of water pressure, the opening and closing member (6) opens the water inlet pipe (5), and the water in the hollow cavity (21) flows outward from the water inlet pipe (5), and at the same time, rainwater continues to enter the water injection port (23), so that the inner wall of the hollow cavity (21) can be washed; Dust reduction spraying is performed by starting the electric valve (42) to open the water outlet pipe (41), starting the water pump (43), and the water pump (43) transports the water in the hollow cavity (21) to the transition pipe (31). The water in the transition pipe (31) is then sprayed out from a plurality of nozzles (32), and the water absorbs the dust in the air to reduce the dust.
