Abstract

The present invention discloses a tower crane sprayer for preventing nozzle blockage, comprising a water outlet pipe fixedly connected to a sprayer body, a plurality of nozzles fixedly connected at equal intervals at the lower end of the water outlet pipe, a plurality of nozzles having a plurality of spray holes at the lower ends of the nozzles, a cleaning frame fixedly connected to the inner wall of the nozzle through a connecting rod, and a sliding plug sealingly and slidably connected to the inner wall of the cleaning frame. When there is no water flow in the water outlet pipe, the sliding plug slides down under the action of a conductive spring, so that the ejector pin is inserted into the water spray hole, thereby preventing dust on the construction site from entering the water spray hole and blocking it when the tower crane sprayer is not in use. When there is water flow in the water outlet pipe, the water-driven wheel drives the rotating shaft to rotate, so that the coil cuts the magnetic induction line between the two permanent magnets and generates current, and the sliding plug slides up under the action of the conductive spring, so that the ejector pin is separated from the water spray hole, and then the water flow is sprayed out through the water spray hole in atomization, thereby performing dust reduction treatment on the dust on the construction site.

Description

Technical Field

[0001] The invention relates to the technical field of spray machines, and in particular to a tower crane spray machine capable of preventing nozzle clogging. Background Art

[0002] A tower crane sprayer is a device that uses a high-pressure pump to transport water to the tower crane at high pressure on the construction site, and sprays it out in atomized form from the nozzle at the lower end of the water pipe on the tower crane to reduce dust on the construction site.

[0003] Due to the harsh environment on the construction site, a large amount of dust will be raised during construction. When the nozzles on the tower cranes are not working, the dust will accumulate and enter the exposed spray holes and adhere to the inner walls of the spray holes. Especially for the nozzles on the tower cranes at low locations, the dust is more likely to accumulate in the spray holes. The dust adhering to the inner walls of the spray holes is difficult to be washed away by water flow and gradually accumulates. As the dust increases, the spray holes will gradually be blocked, reducing the amount of dust sprayed by the nozzles, resulting in unsatisfactory dust reduction effects on the construction site. In addition, since most tower cranes are at high altitudes, it is inconvenient to disassemble the blocked nozzles, which in turn affects the dust reduction treatment on the construction site. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a tower crane sprayer with anti-sprinkler clogging.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A tower crane sprinkler for preventing nozzle clogging comprises a water outlet pipe fixedly connected to a sprinkler body, a plurality of nozzles being fixedly connected at equal intervals at the lower end of the water outlet pipe, a plurality of water spray holes being provided at the lower ends of the plurality of nozzles, a cleaning frame being fixedly connected to the inner wall of the nozzle via a connecting rod, the cleaning frame being sealed and fixedly connected to the inner bottom of the nozzle, a sliding plug being sealingly and slidably connected to the inner wall of the cleaning frame, a plurality of ejectors cooperating with the water spray holes being fixedly connected to the lower end of the sliding plug, a top inside the cleaning frame being fixedly connected to the upper end of the sliding plug via a conductive spring, a filter being fixedly connected to the side wall of the cleaning frame, a debris removal port being provided at the lower end of the nozzle, a plug being threadedly connected to the inner end of the debris removal port, a rotating shaft being rotatably connected to the upper end of the cleaning frame, a water-driven wheel being fixedly connected to the upper side wall of the rotating shaft, and a power supply mechanism for supplying power to the conductive spring being installed in the rotating shaft.

[0007] Preferably, the power supply mechanism includes a vertical rod fixedly connected to the upper end of the cleaning frame, a power generation chamber is opened in the rotating shaft, the vertical rod passes through the lower end of the rotating shaft and extends into the power generation chamber, two permanent magnets with opposite poles attracting each other are symmetrically fixedly connected to the inner wall of the power generation chamber, and a coil is fixedly connected to the side wall of the vertical rod located between the two permanent magnets, and the coil is coupled to a conductive spring.

[0008] The present invention has the following beneficial effects:

[0009] 1. By setting a conductive spring, a sliding plug and an ejector pin, when the tower crane spray machine is not working, the sliding plug, under the action of the conductive spring, allows the ejector pin to be inserted into the water spray hole to seal the water spray hole, thereby preventing dust on the construction site from entering the water spray hole when the tower crane spray machine is not in use, causing blockage of the water spray hole and affecting the dust reduction effect on the construction site;

[0010] 2. By setting a water-driven wheel, a rotating shaft, a vertical rod, a permanent magnet and a coil, when a high-pressure water flow passes through the water outlet pipe, the water-driven wheel will be driven to rotate, so that the rotating shaft drives the permanent magnet to rotate, and then the coil cuts the magnetic induction line between the two permanent magnets, so that current is generated on the coil and the conductive spring is energized. After the conductive spring is energized, it shrinks, so that the sliding plug drives the ejector pin to move upward and separate from the water spray hole, and then the water flows through the cleaning frame into the water spray hole and is sprayed out in atomization to reduce dust on the construction site. The whole process is carried out autonomously, without the need for any power mechanism to drive, and is highly environmentally friendly;

[0011] 3. By setting up a filter, large particles in the high-pressure water flow can be filtered to prevent large particles from entering the cleaning frame and causing the water spray holes to be blocked from the inside, further avoiding blockage of the water spray holes and extending the service life of the nozzle.

Further, the filter screen 9 can filter large particles in the high-pressure water flow to prevent the large particles from entering the cleaning frame 5 and then clogging the water spray hole 3 from the inside. When there is no high-pressure water flow in the water outlet pipe 1, the large particles will accumulate at the debris removal port 10 under the action of gravity. It is only necessary to regularly disassemble the plug and the debris removal port 10 to clean the impurities in the debris removal port 10. The upper end of the cleaning frame 5 is rotatably connected to a rotating shaft 11, and a water impeller 12 is fixedly connected to the upper side wall of the rotating shaft 11. Further, the water impeller 12 is arranged in a wind cup shape, so that the high-pressure water flow in the water outlet pipe 1 can drive the water impeller 12 to rotate quickly, and a power supply mechanism for supplying power to the conductive spring 6 is installed in the rotating shaft 11.

Further, when the water-driven wheel 12 drives the rotating shaft 11 to rotate, the two permanent magnets 15 will continuously rotate along the coil 16. According to the principle of magnetic induction, the coil 16 will cut the magnetic induction lines between the two permanent magnets 15 and generate an induced current, so that the conductive spring 6 is energized and contracts.
