Description

Technical Field

[0001] This invention belongs to the technical field of fence spraying devices, specifically a zoned automated fence spraying device. Background Technology

[0002] In current domestic engineering construction, the construction of fences is indispensable on construction sites. Fences refer to the measures taken to separate the construction site from the external area, making the construction site a relatively closed space.

[0003] With the rapid development of modern industry and the increasing industrialization of construction sites, the amount of dust generated during operations has also increased, seriously affecting the surrounding environment, the site environment, and the health and safety of workers. Therefore, it is necessary to use automated zoned fencing sprinkler systems to separate the construction site from the surrounding area and to block and suppress dust in the construction area, preventing it from affecting the surrounding area. Although existing automated zoned fencing sprinkler systems can spray water to suppress dust at the construction site, the fixed angle of the nozzles makes them very inflexible and the dust removal effect is not good. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide an automated area-based fencing spraying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated area fencing spraying device, comprising a base, on both sides of the top of the base being fixedly installed with columns, a movable tube being movably sleeved inside the top of the column, a spray head located inside the column being fixedly sleeved on the outer surface of the movable tube, the top of the spray head penetrating the column and extending to the outside of the column, an operation box being fixedly installed on the left side of the column, a round shaft being movably sleeved inside the left side of the operation box, the right end of the round shaft penetrating the column and extending into the inside of the column and movably sleeved with the inner wall of the column;

[0015] A fixed box is fixedly connected to the top of the back of the column. A limiting rod is movably sleeved inside the fixed box. The top end of the limiting rod passes through the fixed box and the movable plate and extends above the movable plate, where it is movably sleeved with the inner wall of the movable plate. When the limiting rod moves downward and disengages from the interior of the movable plate, it will release the fixation of the movable plate.

[0016] Preferably, a vertical groove is provided on the back of the fixing box, and a horizontal groove is provided on the back of the fixing box to the left of the vertical groove. A round rod located inside the vertical groove is fixedly installed at the bottom of the back of the limiting rod, and the other end of the round rod passes through the vertical groove and extends to the back of the vertical groove.

[0020] Preferably, a water pump is fixedly installed on the right side of the top of the base, and an inlet pipe is fixedly installed on the back of the water pump.

[0021] Preferably, a water outlet hose is fixedly sleeved on the outside of the movable tube, the bottom end of the water outlet hose is fixedly connected to the top end of the water pump, and a connecting hose is fixedly sleeved between the movable tubes.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention, by setting up a circular shaft, a conveyor belt, a pawl, and a gear, allows the operator to rotate a handle around the circular shaft, causing a rotating plate to drive the circular shaft to rotate, which in turn causes the drive roller to rotate. The drive roller, in conjunction with the conveyor belt, causes the driven roller to rotate, thereby driving the movable tube to rotate and adjusting the nozzle angle. When the operator needs to adjust the nozzle angle downwards, they can lift the fixed plate upwards, causing the pawl to rotate upwards around the fixed shaft. The bottom end of the pawl will disengage from the outer surface of the gear, thus releasing its fixing effect. At this time, the operator can rotate the handle in the opposite direction around the circular shaft to lower the nozzle angle, making the nozzle more flexible to use and achieving a better spraying effect.

[0024] 2. This invention, by setting up a first mounting block, a baffle, a movable plate, and a limiting rod, allows the operator to disassemble the baffle when necessary. By pulling down the round rod, the limiting rod moves downward, disengaging from the movable plate. Then, pushing the round rod to the left allows it to enter the transverse groove, thus fixing the limiting rod. Once the limiting rod disengages from the movable plate, it releases its fixation. The operator can then pull the movable plate outward from its back, releasing the baffle. The operator can then remove the baffle from the first mounting block from top to bottom, facilitating disassembly.

[0025] 3. This invention, by setting up an installation groove, adjustment hole, support rod, and movable rod, allows the operator to remove the bolts from the inside of the connecting plate and the base, thereby releasing the fixing effect on the connecting plate. Then, by pushing the two fixed blocks to move towards each other, the two movable rods will move towards each other, causing the movable rods to disengage from the inside of the adjustment hole, thus releasing the restriction on the support rod. Afterwards, the top of the support rod can be placed at the top of the inside of the installation groove, and then the fixed blocks can be released. Under the elastic recovery action, the fixed spring will push the two movable rods to move in opposite directions, allowing the movable rods to enter the inside of the installation hole, thereby supporting the support rod. This allows the support rod to be placed inside the installation groove, preventing the support rod from being lost when the enclosure is disassembled, and facilitating its continued use next time.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 13 As shown, this embodiment of the invention provides an automated area fencing spraying device. Columns 2 are fixedly installed on both sides of the top of the base 1. A movable tube 3 is movably sleeved inside the top of the column 2. A nozzle 4 located inside the column 2 is fixedly sleeved on the outer surface of the movable tube 3. The top of the nozzle 4 penetrates the column 2 and extends to the outside of the column 2. An operation box 5 is fixedly installed on the left side of the column 2. A round shaft 6 is movably sleeved inside the left side of the operation box 5. The right end of the round shaft 6 penetrates the column 2 and extends into the interior of the column 2, movably sleeved with the inner wall of the column 2.

[0042] The transmission mechanism is located on the left side of the operation box 5;

[0043] A locking mechanism is located inside the operation box 5;

[0044] The locking mechanism includes a fixed shaft 12, the outer surface of which is fixedly sleeved with the inner wall of the operation box 5. The right end of the fixed shaft 12 passes through the operation box 5 and extends into the interior of the operation box 5. A pawl 13 located inside the operation box 5 is movably sleeved on the outer surface of the fixed shaft 12. A first spring 14 is fixedly connected to the upper surface of the pawl 13. The top end of the first spring 14 is fixedly connected to the top of the inner surface of the operation box 5. A fixed plate 15 is fixedly connected to the right side of the pawl 13. When the fixed plate 15 moves upward, it will drive the pawl 13 to rotate upward around the fixed shaft 12. A gear 16 located inside the operation box 5 is fixedly sleeved on the outer surface of the round shaft 6. The outer surface of the gear 16 meshes with the bottom end of the pawl 13.

[0045] When the operator needs to lower the spray angle of the nozzle 4, the fixed plate 15 can be lifted upwards. The fixed plate 15 can drive the pawl 13 to rotate around the fixed shaft 12, thereby causing the bottom end of the pawl 13 to disengage from the outer surface of the gear 16, thus releasing the fixing effect on the gear 16. This allows the operator to lower the spray angle of the nozzle 4 by rotating the round shaft 6. By setting the first spring 14, the first spring 14 can push the pawl 13 downwards under the action of elasticity, thereby resetting the pawl 13.

[0046] The transmission mechanism includes:

[0047] Driven roller 7, the inner surface of driven roller 7 is fixedly sleeved with the outer surface of movable tube 3, the outer surface of round shaft 6 is fixedly sleeved with driving roller 8, driving roller 8 is driven by conveyor belt 9 and driven roller 7, and the outer surface of driving roller 8 is movably connected with the outer surface of column 2.

[0048] The rotating plate 10 has its outer surface fixedly connected to the front end of the round shaft 6, and a handle 11 is movably sleeved inside the right end of the rotating plate 10.

[0049] The operator can rotate the handle 11 around the circular shaft 6, which will cause the rotating plate 10 to drive the circular shaft 6 to rotate, and then cause the drive roller 8 to rotate. The drive roller 8, in cooperation with the conveyor belt 9, causes the driven roller 7 to rotate, which in turn drives the movable tube 3 to rotate, thereby adjusting the spray angle of the nozzle 4.

[0050] The first mounting block 17 is fixedly installed on the front of the column 2, and the second mounting block 18 is fixedly installed on the left side of the column 2. The baffle 19 is movably connected inside the first mounting block 17.

[0051] By setting up the second mounting block 18, the operator can place a baffle 19 inside the second mounting block 18, thereby changing the overall orientation of the enclosure.

[0052] The top of the back of column 2 is equipped with a fixing mechanism, which includes:

[0053] The movable plate 20 has its outer surface movably fitted into the inner wall of the column 2. Both ends of the movable plate 20 penetrate the column 2 and extend to the outside of the column 2. The lower surface of the movable plate 20 is movably connected to the top of the baffle 19.

[0054] The fixed box 21 is fixedly connected to the top of the back of the column 2. The fixed box 21 is movably fitted with a limiting rod 22 inside. The top of the limiting rod 22 passes through the fixed box 21 and the movable plate 20 and extends above the movable plate 20 and is movably fitted with the inner wall of the movable plate 20. When the limiting rod 22 moves downward and disengages from the interior of the movable plate 20, it will release the fixation of the movable plate 20. The bottom end of the limiting rod 22 is movably connected with a second spring 23. The bottom end of the second spring 23 is fixedly connected to the bottom of the inner surface of the fixed box 21.

[0055] By setting a second spring 23, the second spring 23 can push the limiting rod 22 upward under the elastic recovery action, so that the limiting rod 22 can enter the interior of the movable plate 20, thereby fixing the movable plate 20.

[0056] The back of the fixing box 21 has a vertical groove 24 and a horizontal groove 25 located to the left of the vertical groove 24. A round rod 26 located inside the vertical groove 24 is fixedly installed at the bottom of the back of the limiting rod 22. The other end of the round rod 26 passes through the vertical groove 24 and extends to the back of the vertical groove 24.

[0057] The operator can pull the round rod 26 downwards, causing the round rod 26 to move the limiting rod 22 downwards, and then push the round rod 26 to the left, so that the round rod 26 enters the interior of the transverse groove 25, thereby fixing the limiting rod 22.

[0058] The column 2 has a mounting groove 27 on its back side, and adjustment holes 28 are provided on both sides inside the mounting groove 27. Mounting holes 29 are provided on the top of both sides of the mounting groove 27.

[0059] The adjustment holes 28 are designed to be evenly distributed at equal intervals, and operators can select different heights of adjustment holes 28 according to the usage conditions.

[0060] The mounting groove 27 has a support rod 30 movably connected inside, and a connecting plate 34 is hinged to the bottom end of the support rod 30. The connecting plate 34 is fixedly connected to the base 1 by bolts, and a fixing spring 31 is movably sleeved inside the top end of the support rod 30.

[0061] By setting up support rod 30, the support rod 30 can provide support for column 2.

[0062] Both ends of the fixed spring 31 are fixedly connected to movable rods 32. The other end of the movable rod 32 passes through the support rod 30 and extends into the interior of the adjustment hole 28, and is movably sleeved with the adjustment hole 28 and the inner wall of the support rod 30. A fixing block 33 is fixedly installed on the top of the movable rod 32. The top end of the fixing block 33 passes through the support rod 30 and extends above the support rod 30, and is movably connected with the inner wall of the support rod 30.

[0063] The operator can push the two fixed blocks 33 to move towards each other, thereby causing the movable rod 32 to move towards each other, and then causing the movable rod 32 to disengage from the interior of the adjustment hole 28, thereby releasing the limiting effect on the support rod 30.

[0064] A water pump 35 is fixedly installed on the right side of the top of the base 1, and a water inlet pipe 36 is fixedly installed on the back of the water pump 35.

[0065] The operator starts the water pump 35 so that the inlet pipe 36 can draw water in.

[0066] Among them, a water outlet hose 37 is fixedly sleeved on the outside of the movable pipe 3, the bottom end of the water outlet hose 37 is fixedly connected to the top end of the water pump 35, and a connecting hose 38 is fixedly sleeved between the movable pipes 3.

[0067] By setting up a water outlet hose 37, water can enter the interior of the movable pipe 3 through the water outlet hose 37 and then be sprayed out.

[0068] Working principle and usage process:

[0069] When the operator needs to adjust the angle of the nozzle 4, they can rotate the handle 11 around the axis of the circular shaft 6, causing the rotating plate 10 to drive the circular shaft 6 to rotate, thereby causing the drive roller 8 to rotate. The drive roller 8, in conjunction with the conveyor belt 9, causes the driven roller 7 to rotate, thereby causing the movable tube 3 to rotate, thus enabling the adjustment of the nozzle 4 angle. When the operator needs to lower the spray angle of the nozzle 4, they can lift the fixed plate 15 upwards, causing the fixed plate 15 to drive the pawl 13 to rotate upwards around the fixed shaft 12, thereby causing the bottom end of the pawl 13 to disengage from the outer surface of the gear 16, thus releasing the fixing effect on the gear 16. At this time, the operator can rotate the handle 11 in the opposite direction around the axis of the circular shaft 6, thereby lowering the angle of the nozzle 4. This provides greater flexibility and can achieve better spraying results.

[0070] When the operator disassembles the baffle 19, the round rod 26 can be pulled downwards, causing the round rod 26 to move the limiting rod 22 downwards, thereby disengaging the limiting rod 22 from the interior of the movable plate 20. The operator can then push the round rod 26 to the left, causing it to enter the interior of the transverse groove 25, thus fixing the limiting rod 22. At this point, the operator can pull the movable plate 20 outwards from the back of the movable plate 20, thereby releasing the fixing effect on the baffle 19. Then, the baffle 19 can be removed from the interior of the first mounting block 17 from top to bottom, which facilitates the disassembly of the baffle 19, shortens the disassembly and assembly cycle, and saves construction costs.

[0071] First, the operator removes the bolts from the inside of the connecting plate 34 and the base 1, thereby releasing the fixing effect on the connecting plate 34. Then, by pushing the two fixing blocks 33 to move in opposite directions, the two movable rods 32 will move in opposite directions, causing the movable rods 32 to disengage from the inside of the adjusting hole 28, thus releasing the limiting effect on the support rod 30. At this time, the operator places the top of the support rod 30 at the top inside the mounting groove 27, and then releases the fixing blocks 33. Under the restoring force of the fixing spring 31, the two movable rods 32 will be pushed to move in opposite directions, causing the movable rods 32 to enter the inside of the mounting hole 29, thereby supporting the support rod 30. This allows the support rod 30 to be placed inside the mounting groove 27, preventing the support rod 30 from being lost when the enclosure is disassembled, and facilitating its continued use next time.
