Description

Technical Field

[0001] The invention relates to the technical field of highway environmental protection construction, in particular to a spray device for highway environmental protection construction. Background Art

[0002] During the construction of highway projects, the loading and unloading of materials such as cement, concrete, asphalt, sand and gravel, as well as the vehicles passing on the road, usually generate dust during the material transportation and operation process at the construction site. The dust will affect the health of the construction workers. Therefore, during the construction of highway projects, water mist is usually sprayed to suppress the flying of dust, thereby improving the quality of the construction environment and protecting the health of the construction workers.

[0003] In the existing dust removal, a plurality of atomizing nozzles are usually connected in series through a water pipe, and the atomizing nozzles are fixed on the highway fence. Then, water is pumped into the atomizing nozzles through the water pipes, so that the atomizing nozzles spray water in the form of atomization to remove the dust on the construction site. Due to the influence of factors such as wind force and different construction sites, the dust density on different sections of the road usually changes. Therefore, it is necessary to adjust the spraying amount of the atomizing nozzle to ensure that the water mist can completely remove the dust, while preventing excessive spraying amount from causing excessive moisture on the construction site and affecting the construction progress.

[0004] The following problems exist in the existing dust removal: 1. Since a large number of atomizing nozzles are usually installed at the construction site, it takes a lot of time to manually adjust the spraying volume of the atomizing nozzle, resulting in reduced work efficiency; 2. When the atomizing nozzle is spraying water mist, it is impossible to quickly adjust the spraying angle of the atomizing nozzle, which may result in the water mist sprayed by the atomizing nozzle failing to completely cover the dust, thereby making it impossible to completely remove the dust on the construction site, affecting the dust removal effect.

Then, two adjacent three-way pipes 1 are connected through the water pipe 2, and the left pipe of the leftmost three-way pipe 1 is connected to the external water pump, and the right pipe of the rightmost three-way pipe 1 is blocked. Then, the water pump is started to inject water into the leftmost three-way pipe 1, and the water can be injected into each spray device 3 through the water pipe 2 and the three-way pipe 1, so that the spray device 3 sprays water in the form of atomization to achieve dust removal on the construction site.

[0031] When it is necessary to adjust the spraying amount of water mist, the water mist spraying amount of the spray device 3 is adjusted by controlling the adjusting device 5 using water pressure, and a connecting pipe 6 is connected between two adjacent adjusting devices 5, so that the water pressure in multiple adjusting devices 5 and the connecting pipe 6 is equal everywhere. When one adjusting device 5 is controlled to adjust the spraying amount of its corresponding spray device 3 using water pressure, the remaining adjusting devices 5 can synchronously adjust the spraying amount of their corresponding spray devices 3, thereby realizing synchronous adjustment of the spraying amount of the spray device 3.

[0032] See also Figure 1-Figure 3 The locking device 4 includes two connecting sleeves 41 rotatably sleeved on the outside of the three-way pipe 1, and the lower ends of the two connecting sleeves 41 are fixedly installed with a square plate 42.

A double-headed screw 44 is rotatably connected to the square plate 42, and the two threaded sections have opposite rotation directions. The two clamping plates 43 are respectively threadedly connected to the corresponding threaded sections; the outside of the three-way pipe 1 and located on the opposite sides of the two connecting sleeves 41 are provided with a circular plate 12 that is slidably sleeved on the left and right through a connecting spring 11, and a plurality of circumferentially evenly arranged locking rods 13 are fixedly installed on the opposite sides of the two circular plates 12, and a plurality of circumferentially evenly arranged locking holes are opened on the opposite sides of the two connecting sleeves 41, and the locking holes are used to cooperate with the locking rods 13 to lock the connecting sleeves 41.

[0033] The locking device 4 is used to fix the position of the three-way pipe 1; specifically, after the three-way pipe 1 is placed on the guardrail, the double-headed screw 44 is controlled to drive the two clamping plates 43 to move toward each other, so that the two clamping plates 43 are clamped on the guardrail, and then the two circular plates 12 are moved in the direction away from each other and the connecting spring 11 is compressed, so that the circular plate 12 drives the locking rod 13 to move out of the locking hole and releases the lock of the connecting sleeve 41, and then the three-way pipe 1 is rotated, so that the three-way pipe 1 drives the spray device 3 to rotate a certain angle, and the two circular plates 12 are moved in the direction of approaching each other under the action of the connecting spring 11 and inserted into the corresponding locking holes, thereby realizing the rapid adjustment of the spraying angle of the spray device 3, and a plurality of locking rods 13 are provided to increase the stability of the spray device 3 during spraying operation.

[0034] See also Figure 1 and Figure 2 The spray device 3 includes a spray pipe 31 fixedly installed on the upper end of the three-way pipe 1, a spray head 32 is arranged on the upper side of the spray pipe 31, and the inner wall of the spray pipe 31 and the outer wall of the spray head 32 are slidably arranged, and a filter unit 33 for filtering water flow is connected between the spray head 32 and the spray pipe 31; wherein, the spray head 32 is provided with a plurality of spray port groups evenly arranged up and down, and each spray port group includes a plurality of spray ports evenly arranged circumferentially.

[0035] The spray device 3 is used to spray water mist; specifically, when the water flow flows into the three-way pipe 1, the water flow can flow into the spray pipe 31 through the vertical section of the three-way pipe 1, and flow into the spray head 32 along the spray pipe 31, so that the water flow is sprayed out from the spray head 32 in the form of atomization. At the same time, the filter unit 33 can filter the water flow to prevent impurities in the water flow from clogging the spray head 32.

[0036] See also Figure 1 , Figure 2 and Figure 4 The regulating device 5 includes a fixed column 51 fixedly installed in the spray pipe 31, a water hole penetrating through the upper and lower ends of the fixed column 51 is opened in the middle part, an annular groove 52 is opened in the fixed column 51, a water inlet hole 53 connected to the annular groove 52 is opened at the right part of the lower end of the leftmost fixed column 51, a blocking unit 54 for opening and closing the water inlet hole 53 is installed in the leftmost fixed column 51, and a control unit 55 for regulating the water pressure in the annular groove 52 is installed on the left side of the leftmost fixed column 51; mounting pipes 56 are fixedly installed at the lower parts of the opposite sides of two adjacent fixed columns 51, and one end of the mounting pipe 56 away from the fixed column 51 penetrates the spray pipe 31 and is connected to its corresponding connecting pipe 6, a matching unit 57 is installed in the annular groove 52, and the matching unit 57 is connected to the spray head 32, and the matching unit 57 is used to cooperate with the water pressure in the annular groove 52 to adjust the position of the spray head 32.

[0037] The regulating device 5 is used to adjust the spraying amount of the sprinkler head 32; specifically, when water flows into the sprinkler pipe 31, the water can enter the sprinkler head 32 through the water hole, and at the same time, the water can flow into the annular groove 52 through the water inlet hole 53, so that the water can flow into each annular groove 52 through the installation pipe 56 and the connecting pipe 6. When the water flow fills the annular groove 52, the installation pipe 56 and the connecting pipe 6, the blocking unit 54 is controlled to block the water inlet hole 53, so that the water flow no longer flows through the water inlet hole 53. The annular groove 52 is inserted into the annular groove 52, so that the annular groove 52, the mounting pipe 56 and the connecting pipe 6 form a closed space. When the spraying amount of the sprinkler head 32 needs to be adjusted, the control unit 55 reduces the water pressure in the annular groove 52, the mounting pipe 56 and the connecting pipe 6, so that the matching unit 57 corresponding to each annular groove 52 drives the sprinkler head 32 to move downward, so that the spray pipe 31 can block part of the spray holes of the sprinkler head 32, thereby realizing the spraying amount adjustment of the sprinkler head 32.

[0038] See also Figure 2 , Figure 4 and Figure 5 The matching unit 57 includes a sealing plate 571 which is slidably mounted on the upper side of the annular groove 52. The upper end of the sealing plate 571 is connected to the inner wall of the annular groove 52 through a plurality of return springs 572 which are evenly arranged in the circumferential direction. An adjusting sleeve 573 is fixedly mounted on the upper end of the sealing plate 571, and the upper end of the adjusting sleeve 573 slides up and down through the upper end of the fixed column 51. The upper and middle part of the outer side of the adjusting sleeve 573 is set as a threaded structure. A matching ring 321 is fixedly mounted on the lower inner side of the spray head 32, and the matching ring 321 is mounted on the outer side of the threaded structure of the adjusting sleeve 573 by threaded matching. A sealing baffle 574 is fixedly mounted on the upper outer side of the adjusting sleeve 573. Two symmetrically arranged air holes 311 are provided on the spray pipe 31 and above the fixed column 51. A pressure relief valve 312 is fixedly mounted on the rear end of the spray pipe 31, and the pressure relief valve 312 is connected to the annular groove 52. A plurality of through holes 511 connected to the annular groove 52 are provided on the upper end of the fixed column 51.

[0039] The matching unit 57 is used to cooperate with the water pressure in the annular groove 52 to adjust the position of the sprinkler head 32; specifically, initially, the pressure relief valve 312 is in an open state, and then when water is injected into the multiple annular grooves 52, the mounting tube 56 and the connecting tube 6, the pressure relief valve 312 can discharge the air in the multiple annular grooves 52, the mounting tube 56 and the connecting tube 6 to ensure that the water can fill the multiple annular grooves 52, the mounting tube 56 and the connecting tube 6, and when the water fills the multiple annular grooves 52, the mounting tube 56 and the connecting tube 6, the pressure relief valve 312 is closed.

[0040] When the water pressure in the annular groove 52, the mounting tube 56 and the connecting tube 6 decreases, the sealing plate 571 moves downward synchronously under the action of the water pressure and stretches the reset spring 572, so that the sealing plate 571 drives the sprinkler head 32 to move downward through the adjusting sleeve 573, so that the sprinkler pipe 31 can block part of the sprinkler holes of the sprinkler head 32, thereby realizing the adjustment of the spraying amount of the sprinkler head 32, and the water pressure in multiple annular grooves 52, the mounting tube 56 and the connecting tube 6 is equal everywhere, thereby realizing the synchronous adjustment of the spraying amount of the sprinkler heads 32, and thus there is no need to adjust the spraying amount of the sprinkler heads 32 one by one. When the sealing plate 571 moves up and down under the action of the water pressure, the air can flow into or out of the part between the upper end of the sealing plate 571 and the annular groove 52 through the air hole 311 and the through hole 511, ensuring that the sealing plate 571 can move smoothly.

[0041] When it is necessary to adjust the spraying amount of a single sprinkler head 32, the spray head 32 is screwed to drive the matching ring 321 to rotate, so that the threaded structure of the matching ring 321 and the adjusting sleeve 573 cooperates to drive the sprinkler head 32 to move up and down, thereby realizing the adjustment of the spraying amount of the single sprinkler head 32. Water can enter the sprinkler head 32 through the water hole and the adjusting sleeve 573, and the sealing baffle 574 can limit the upper limit position of the matching ring 321, and seal between the sprinkler head 32 and the adjusting sleeve 573 to prevent water leakage.

[0043] See also Figure 4 The control unit 55 includes a round tube 551 fixedly installed on the lower left side of the leftmost fixed column 51, the left end of the round tube 551 passes through the spray pipe 31 and is fixedly installed with an adjusting cylinder 552, and the adjusting cylinder 552 is fixedly installed on the outside of the spray pipe 31, a piston 553 is slidably installed left and right in the adjusting cylinder 552, an adjusting screw 554 is rotatably installed on the left end of the piston 553, and the adjusting screw 554 is connected to the adjusting cylinder 552 by threaded fitting, and a pushing block 556 is fixedly installed in the middle of the right end of the piston 553 through a connecting rod 555, and the pushing block 556 is used to push the matching rod 521 to move rightward.

[0044] The blocking unit 54 is used to open and close the water inlet 53, and the control unit 55 is used to adjust the water pressure in the multiple annular grooves 52, the mounting tube 56 and the connecting tube 6; specifically, the adjusting screw 554 is screwed to drive the piston 553 to move to the right limit position, so that the piston 553 drives the push block 556 to move to the right limit position through the connecting rod 555, and then the push block 556 pushes the matching rod 521 to move to the right limit position, so that the matching rod 521 and the oblique groove of the blocking plate 543 cooperate to drive the blocking plate 543 to rotate, so that the circular hole of the blocking plate 543 and the water inlet 53 are aligned, so that water can flow through the water inlet hole 53 and the circular hole are in the annular groove 52, and then the adjusting screw 554 drives the piston 553 to move left, so that the piston 553 drives the pushing block 556 to move left through the connecting rod 555, and then the blocking plate 543 rotates to the initial position under the action of the tension spring 542, and the circular hole and the water inlet hole 53 are no longer aligned, so that the blocking plate 543 closes the water inlet hole 53. When the water pressure needs to be adjusted, the adjusting screw 554 is controlled to drive the piston 553 to move left, so that there is a certain distance between the right end of the piston 553 and the right side of the adjusting cylinder 552, and then the sealing plate 571 moves downward under the action of the water pressure.

[0046] The filter unit 33 is used to filter water; specifically, when water flows into the spray pipe 31, the two filter plates 331 can filter the water to prevent impurities from clogging the spray head 32. When the spraying amount of a single spray head 32 is adjusted, the lower filter plate 331 is driven to rotate a certain angle by manually twisting the rotating rod 332, so that the filter holes of the two filter plates 331 arranged upper and lower are arranged alternately, so that the water flow no longer enters the spray pipe 31, and the single spray head 32 no longer performs the spraying operation, thereby facilitating the adjustment of the spray head 32.
