Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a dust suppression device for road construction. Background Technology

[0002] During municipal road construction, a lot of dust is generated. This dust not only pollutes the surrounding environment but also poses a health hazard to workers. Therefore, fog cannons are needed to suppress dust during construction. The working principle of a fog cannon is to atomize water using a high-pressure fan. It is also equipped with a spraying device. The water mist sprayed by the device can adsorb dust particles suspended in the air, thereby achieving the effects of cooling the road surface, removing dust, cleaning, and purifying the air.

[0003] Fog cannons are subject to environmental limitations during use, making it inconvenient to replenish water sources. Each time water is replenished, the device must be stopped and moved to the water source, which greatly reduces the dust suppression effect in the construction area. Although additional water buckets can provide some water, the device requires a large amount of water, and multiple trips are needed, which consumes a lot of physical strength for construction workers. Moreover, since the cleanliness of the replenished water source cannot be guaranteed, the device is equipped with a water filtration structure, but the filtered impurities remain inside the device and are difficult to clean. Therefore, this application proposes a road construction dust suppression device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a road construction dust suppression device to solve the problems in the above-mentioned background technology that require moving the entire device and stopping the operation of the device when replenishing water, and that the replenished water cannot be filtered.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a road construction dust suppression device includes a box body, a water storage chamber on the left side of the box body, and a storage chamber on the right side of the box body. A water tank is installed in the storage chamber, a second water pipe is fixedly installed on the side wall of the water tank, a first water pipe communicating with the water storage chamber is fixedly installed on the side wall of the box body, and the first water pipe is connected to the second water pipe. A water suction pipe extending to the bottom of the water storage chamber without contacting its bottom is inserted through the top of the box body. Two first slots are opened at the bottom of the storage chamber. Second rollers located in the two first slots are fixedly installed at the four corners of the bottom of the water tank. First rollers are fixedly installed at the four corners of the bottom of the box body. Limiting components are provided at the two corners of the top right side of the box body.

[0006] Optionally, the bottom of the water tank cavity is higher than the bottom of the water storage cavity. An inclined filter screen is installed inside the water storage cavity near the side of the first water pipe. An opening extending to the outside of the tank is opened at the bottom of the side wall of the water storage cavity connected to the first water pipe. A drain pipe is fixedly installed at the opening on the side wall of the tank. A drain inlet is opened on the side wall of the drain pipe to connect with the opening. A sealing cap is threaded onto the end of the drain pipe.

[0007] Optionally, a second slot is provided on the side wall of the tank. When the water tank is located in the storage cavity, the second water pipe on the side wall of the water tank is located in the second slot. A limiting plate is fixedly installed on the outer wall of the second water pipe connecting to the first water pipe. A threaded sealing pipe that abuts against the side of the limiting plate is threaded between the connecting ends of the first water pipe and the second water pipe. Valves are provided on both the first water pipe and the second water pipe.

[0008] Optionally, the limiting assembly includes a fixing bolt, a baffle, a fixing member, and a limiting bolt. The fixing bolt is fixedly installed at the upper position on both sides of the right end of the housing. The fixing member is fixedly installed at the top of the right end of the housing. A notch is provided on the fixing member. One end of the baffle is rotatably connected to the fixing bolt, and the other end of the baffle can be rotated into the notch on the fixing member. A slot is provided at the other end of the baffle. The limiting bolt passes through and is inserted into the outside of the fixing member. One end of the limiting bolt extends into the notch and can be inserted into the slot on the baffle. A spring is fixedly connected between the limiting bolt and the fixing member.

[0009] Optionally, a first water injection pipe connected to the water storage chamber is fixedly installed on the top of the side wall of the tank where the sewage pipe is installed, and a second water injection pipe is fixedly installed on the top of the water tank. A third slot is opened at the right end of the bottom of the storage chamber. When the water tank is located in the storage chamber, the second water injection pipe is located in the third slot. A handle is fixedly installed on the right side of the water tank.

[0010] Optionally, a rotating support frame is provided on the top of the housing, and a mist cannon is installed between the top of the rotating support frame. A ring-shaped water spray pipe is provided on the inner wall of the left end of the mist cannon. The end of the water pump located outside the water storage chamber is connected to the water spray pipe. A water pump connected to the water pump is installed on the top of the housing. A clamp for engaging the water pump is fixedly installed at the bottom of the mist cannon. A high-pressure blower is provided at the right end of the mist cannon.

[0011] The beneficial effects of this utility model are:

[0012] 1. Due to the difference in height between the bottom of the water tank and the storage chamber, the water in the tank will be used up first, leaving some water in the storage chamber. To replenish the storage chamber, first close the valves on the first and second water pipes. Then, turn the threaded sealing pipe to separate the first and second water pipes. Next, pull the limit bolt to disengage it from the slot on the baffle, and move the baffle to remove it from obstructing the water tank. Pulling the handle will then allow the water tank to be pulled out of the storage chamber. This allows for individual movement of the water tank for replenishment. After replenishment, push the tank back into the storage chamber. Reconnect the second water pipe to the first water pipe, and then use a threaded sealing pipe to complete the connection between the two. After the connection is complete, open both valves. Water in the tank will then flow into the storage chamber through the second and first water pipes. Finally, use the limiting component to restrict the position of the water tank. Replenishing water by moving the water tank separately can prevent the device from stopping. Moreover, moving the water tank is more convenient and less labor-intensive than moving the entire device. Compared to using a bucket to replenish water, the water tank is easier to move, and the amount of water replenished to the storage chamber each time is much greater than that of a bucket, thus reducing the frequency of water replenishment.

[0013] 2. When water is replenished to the water storage chamber through the first water inlet pipe and the first water pipe, the water entering the water storage chamber must pass through the filter screen before reaching the bottom of the pumping pipe. The filter screen can intercept and filter impurities and other substances in the water source. The intercepted impurities and other substances are deposited at the bottom of the water storage chamber along the slope of the filter screen. Then, the accumulated impurities will enter the drain pipe through the opening and the sewage inlet at the bottom of the side wall of the tank, thereby collecting the sedimented impurities inside the water storage chamber. When the device is not in use, the sealing cap at the end of the drain pipe can be opened to handle the debris inside, thus facilitating the treatment of the impurities and other substances filtered and intercepted inside the water storage chamber.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a road construction dust suppression device, including a housing 1. A water storage chamber 2 is provided on the left side of the housing 1, and a storage chamber 3 is provided on the right side of the housing 1. A water tank 6 is installed inside the storage chamber 3. A second water pipe 7 is fixedly installed on the side wall of the water tank 6. A first water pipe 5, communicating with the water storage chamber 2, is fixedly installed on the side wall of the housing 1, and the first water pipe 5 is connected to the second water pipe 7. A suction pipe 4, extending to the bottom of the water storage chamber 2 but not in contact with its bottom, is inserted through the top of the housing 1. Two first slots 11 are provided at the bottom of the storage chamber 3. At the four corners of the bottom of the water tank 6... Each of the two first slots 11 is fixedly installed with a second roller 12, and each of the four corners at the bottom of the box 1 is fixedly installed with a first roller 13. Each of the two corners at the top right side of the box 1 is provided with a limit component 14. Because the bottom of the inner cavity of the water tank 6 is higher than the bottom of the inner cavity of the water storage cavity 2, the water in the water tank 6 will be used up first. Then the first water pipe 5 and the second water pipe 7 are separated, and the water tank 6 is pulled out from the storage cavity 3 to replenish the water in the water tank 6. The water pumping pipe 4 can still draw the remaining water in the water storage cavity 2, so as to complete the water replenishment step without stopping the operation of the device.

[0024] like Figure 1 , Figure 5 and Figure 6As shown, the bottom of the inner cavity of the water tank 6 is higher than the bottom of the inner cavity of the water storage chamber 2. An inclined filter screen 9 is provided inside the water storage chamber 2 near the side of the first water pipe 5. The bottom of the side wall of the water storage chamber 2 connected to the first water pipe 5 has an opening extending to the outside of the tank body 1. A drain pipe 10 is fixedly installed at the opening on the side wall of the tank body 1. The side wall of the drain pipe 10 has an inlet that connects with the opening. A sealing cap is threaded onto the end of the drain pipe 10. Impurities and other substances in the water source can be intercepted and filtered through the filter screen 9. The intercepted impurities and other substances are deposited at the bottom of the water storage chamber 2 along the inclined surface of the filter screen 9. The accumulated impurities will then converge into the drain pipe 10 through the opening and the inlet on the side wall of the tank body 1. The impurities inside the drain pipe 10 can be treated by unscrewing the sealing cap at the end of the drain pipe 10.

[0025] like Figure 2 and Figure 3 As shown, the side wall of the box 1 has a second slot. When the water tank 6 is located in the storage cavity 3, the second water pipe 7 on the side wall of the water tank 6 is located in the second slot. A limiting plate is fixedly installed on the outer wall of the second water pipe 7 and the first water pipe 5. A threaded sealing pipe 8 is threaded between the joint ends of the first water pipe 5 and the second water pipe 7 and abuts against the side of the limiting plate. Valves are provided on both the first water pipe 5 and the second water pipe 7. The first water pipe 5 and the second water pipe 7 can be connected through the threaded sealing pipe 8, while the valve can prevent water leakage after the first water pipe 5 and the second water pipe 7 are separated.

[0026] like Figure 3 and Figure 4 As shown, the limiting assembly 14 includes a fixing bolt 141, a baffle 142, a fixing member 143, and a limiting bolt 144. The fixing bolt 141 is fixedly installed on the upper part of both sides of the right end of the housing 1. The fixing member 143 is fixedly installed on the top of the right end of the housing 1, and a notch is provided on the fixing member 143. One end of the baffle 142 is rotatably connected to the fixing bolt 141, and the other end of the baffle 142 can be rotated into the notch on the fixing member 143. A slot is provided on the other end of the baffle 142. The limiting bolt 144 penetrates and is inserted into the outer side of the fixing member 143, and limits... One end of the positioning bolt 144 extends into the notch and can be inserted into the slot on the baffle 142. A spring is fixedly connected between the positioning bolt 144 and the fixing member 143. The water tank 6 can be restricted in the storage cavity 3 by the limiting component 14, so that the water tank 6 cannot move freely in the storage cavity 3. In this way, when the box body 1 is moved, the water tank 6 can be moved along with it. When the top of the baffle 142 is connected to the fixing member 143 under the restriction of the positioning bolt 144, the baffle 142 is tilted at 45° and intercepts the corner of the top right side of the water tank 6.

[0027] like Figure 2 and Figure 3As shown, a first water injection pipe 20 connected to the water storage chamber 2 is fixedly installed on the top of the side wall of the tank 1 where the sewage pipe 10 is installed. Water can be injected into the water storage chamber 2 through the first water injection pipe 20. A second water injection pipe 21 is fixedly installed on the top of the water tank 6. Water can be injected into the water tank 6 through the second water injection pipe 21. A third slot is opened at the right end of the bottom of the storage chamber 3. When the water tank 6 is located in the storage chamber 3, the second water injection pipe 21 is located in the third slot. A handle is fixedly installed on the right side of the water tank 6. The handle makes it easy to pull the water tank 6 out of the storage chamber 3 and to move the water tank 6.

[0028] like Figure 1 and Figure 2 As shown, a rotating support frame 15 is provided on the top of the housing 1, and a mist cannon 16 is mounted between the top ends of the rotating support frame 15. A circular water spray pipe 18 is provided on the inner wall of the left end of the mist cannon 16. The end of the water suction pipe 4 located outside the water storage chamber 2 is connected to the water spray pipe 18. A water pump 19 connected to the water suction pipe 4 is installed on the top of the housing 1. A clamp is fixedly installed at the bottom of the mist cannon 16 to engage the water suction pipe 4. The position of the water suction pipe 4 can be fixed by the clamp. A high-pressure blower 17 is provided at the right end of the mist cannon 16. The water source in the water storage chamber 2 can be pumped into the water spray pipe 18 by the water pump 19 and sprayed out. The water is atomized under the action of the high-pressure blower 17.
