Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to an environmentally friendly sprinkler device for municipal engineering. Background Technology

[0002] Municipal engineering refers to a series of public infrastructure construction projects invested in, constructed, and managed by the government, directly serving the daily lives of urban residents and the overall operation and development of the city. It covers many key areas of urban life, such as the planning and paving of urban roads, the construction of bridges, and the development of water supply and drainage systems. It is the fundamental support for the normal operation and sustainable development of a city, playing a vital role in improving the quality of life for urban residents and promoting urban economic and social development. Municipal construction often generates a large amount of dust, which has a negative impact on the environment. Therefore, water spraying devices are often used to suppress dust during construction.

[0003] To increase the spraying range, existing sprinkler systems typically add electric actuators to control the rotation of the nozzles and change the spray angle. However, the additional electric actuators not only increase the cost of the sprinkler system, but they are also prone to failure during long-term use, increasing maintenance costs. Furthermore, the electric actuators rely on electricity, increasing energy consumption, which is not in line with the current trend of energy conservation and environmental protection. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly sprinkler device for municipal engineering, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An environmentally friendly sprinkler system for municipal engineering includes a water storage tank. A water pump is installed inside the tank, and the outlet of the pump is connected to a water outlet pipe. The end of the water outlet pipe extends to the outside of the water storage tank and is fitted with a horizontal pipe. Multiple spray nozzles are rotatably mounted on the surface of the horizontal pipe via a rotary joint, and nozzles are mounted at the ends of the spray nozzles. A column is installed inside the water outlet pipe, and a first rotating shaft is rotatably mounted inside the column via a rotating mechanism.

A fixing plate is mounted on the outer surface of the rack, and a limit groove is provided on the surface of the fixing plate. A lever is provided on the upper surface of the turntable, and the lever is located within the limit groove.

[0010] Furthermore, a through groove is provided on the surface of the turntable, a screw is rotatably installed inside the through groove, a nut seat is installed on the outer surface of the screw, the nut seat fits against the inner wall of the through groove, and the lever is installed on the nut seat.

[0011] Furthermore, the length direction of the through groove is consistent with the radius direction of the turntable.

[0012] Furthermore, a protective cover is installed on the outer surface of both the outlet pipe and the horizontal pipe. The protective cover is located on the outside of the transmission mechanism, and the rack is slidably connected to the inner wall of the protective cover. An inspection door is provided on the protective cover.

[0013] Furthermore, this also includes the base plate. The water storage tank is installed on the base plate, and casters are installed at the four corners of the bottom of the base plate. A handrail is installed on the upper surface of the base plate away from the nozzle.

[0014] Furthermore, a control switch is installed on the handrail, which is electrically connected to the water pump.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model, through the setting of a rotating mechanism, can drive the turntable to rotate during the water flow transportation process, and under the action of the transmission mechanism, drive the spray pipe to rotate back and forth, thereby continuously changing the spray angle, increasing the dust suppression range, and eliminating the need for an additional drive source, thus reducing the purchase cost, maintenance cost and energy consumption of the device, which is in line with the current development trend of energy conservation and environmental protection.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides an environmentally friendly sprinkler device for municipal engineering, comprising a water storage tank 1, a water pump installed inside the water storage tank 1, an outlet pipe 101 connected to the outlet end of the water pump, an end of the outlet pipe 101 extending to the outside of the water storage tank 1 and fitted with a horizontal pipe 102, a plurality of spray pipes 104 rotatably mounted on the surface of the horizontal pipe 102 via a rotary joint 103, and nozzles 105 mounted at the ends of the spray pipes 104. A column 106 is installed inside the outlet pipe 101, and a first rotating shaft 107 is rotatably mounted inside the column 106 via a rotating mechanism 2, which drives the first rotating shaft 107 to rotate under the flow of water. A turntable 108 is installed at the top of the first rotating shaft 107 extending to the outside of the column 106, and a transmission mechanism 3 is provided between the turntable 108 and the spray pipes 104, which drives the spray pipes 104 to reciprocate when the turntable 108 rotates.

[0026] When in use, the water pump is started to draw water from the water storage tank 1 into the horizontal pipe 102 through the water outlet pipe 101, and then sprays it out from the nozzle 105 through the spray pipe 104 to form a water mist, which can play a role in dust suppression. When the water flows in the water outlet pipe 101, under the action of the rotating mechanism 2, it can drive the first rotating shaft 107 to rotate. The first rotating shaft 107 drives the turntable 108 to rotate, and under the action of the transmission mechanism 3, it drives the spray pipe 104 to rotate back and forth, thereby continuously changing the spray angle and increasing the dust suppression range. Moreover, no additional drive source is required, which reduces the purchase cost, maintenance cost and energy consumption of the device, which is in line with the current development trend of energy conservation and environmental protection.

[0027] The top of the water storage tank 1 is equipped with a water inlet for adding water into the water storage tank 1, and the water inlet is equipped with a cover to prevent impurities from falling into the water storage tank 1 and reduce the possibility of the nozzle 105 becoming clogged.

[0028] Preferably, the rotating mechanism 2 includes a second rotating shaft 201 rotatably mounted on the column 106. One end of the second rotating shaft 201 extends to the outside of the column 106 and is equipped with an impeller 202. The other end of the second rotating shaft 201 extends to the inside of the column 106 and is equipped with a first bevel gear 203. A second bevel gear 204 is mounted on the outer surface of the first rotating shaft 107, and the second bevel gear 204 meshes with the first bevel gear 203.

[0029] The impeller 202 rotates under the impact of the water flow, which in turn drives the second shaft 201 to rotate. The second shaft 201 drives the first bevel gear 203 to rotate. Since the first bevel gear 203 and the second bevel gear 204 mesh with each other, the first bevel gear 203 can drive the second bevel gear 204 to rotate, thereby achieving the purpose of driving the first shaft 107 to rotate.

[0030] The transmission ratio of the first bevel gear 203 and the second bevel gear 204 is 4:1. When the impeller 202 rotates four times, the turntable 108 will rotate one time, thereby driving the nozzle 104 to rotate slowly back and forth.

[0031] Preferably, the transmission mechanism 3 includes a gear 301 mounted on the outer surface of the nozzle 104, and a rack 302 disposed on the outer side of the nozzle 104, the rack 302 being meshed with the gear 301. A fixing plate 303 is mounted on the outer surface of the rack 302, and a limiting groove 304 is provided on the surface of the fixing plate 303. A lever 305 is provided on the upper surface of the turntable 108, and the lever 305 is disposed within the limiting groove 304.

[0032] When the turntable 108 rotates, it can drive the lever 305 to rotate. The lever 305 applies a thrust to the inner wall of the limiting groove 304, which can drive the rack 302 to reciprocate. Since the rack 302 and the gear 301 mesh with each other, the purpose of driving the nozzle 104 to reciprocate can be achieved.

[0033] Preferably, the surface of the turntable 108 is provided with a through groove 4, a screw 401 is rotatably mounted inside the through groove 4, a nut seat 402 is mounted on the outer surface of the screw 401, the nut seat 402 is in contact with the inner wall of the through groove 4, and the lever 305 is mounted on the nut seat 402. The length direction of the through groove 4 is consistent with the radius direction of the turntable 108.

[0034] When the screw 401 is turned, the inner wall of the through groove 4 limits the nut seat 402, thus causing the nut seat 402 to move along the length of the screw 401. The nut seat 402 then moves the lever 305, thereby adjusting the distance between it and the center of the turntable 108, changing the amount of movement of the rack 302 and the rotation angle of the nozzle 104, and adjusting the dust suppression range.

[0035] Preferably, a protective cover 5 is installed on the outer surface of the water outlet pipe 101 and the horizontal pipe 102. The protective cover 5 is located on the outside of the transmission mechanism 3, and the rack 302 is slidably connected to the inner wall of the protective cover 5. An inspection door 501 is provided on the protective cover 5.

[0036] The protective cover 5 provides external protection for the transmission mechanism 3, preventing dust, impurities and other foreign objects from adhering to the rack 302 and gear 301 and affecting their performance. In addition, the protective cover 5 also provides a limiting function for the rack 302, enabling it to achieve reciprocating motion under the action of the lever 305.

[0037] Preferably, it also includes a base plate 6. The water storage tank 1 is installed on the base plate 6, and casters 601 are installed at the four corners of the bottom of the base plate 6. A handrail 602 is installed on the side of the upper surface of the base plate 6 away from the nozzle 105.

[0038] The water storage tank 1 can be easily moved, improving the flexibility of the device.

[0039] Preferably, a control switch 603 is provided on the handrail 602, and the control switch 603 is electrically connected to the water pump.

[0040] The operator can control the water pump through the control switch 603. Since the control switch 603 is located on the handrail 602, it is easily accessible to the hand and convenient to operate.
