Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a rotary spray head and a multifunctional high-altitude rotary spray dust suppression device. Background Art

[0002] In order to solve the problem of high-altitude dust in municipal roads, construction sites, ports, open-pit mines, and enterprise plants, cleaning and sweeping vehicles, sprinkler trucks, vehicle-mounted fog cannons, fog piles and other equipment are generally used for dust suppression. In particular, there are many cases of using fog piles in steel, coking, cement, ceramics, thermal power plant plants and material sheds.

[0003] Mist piles are usually composed of pile poles, host machines, electronic control systems, rotary spray heads, pipeline systems, nozzles, etc. They use high-pressure water jet technology to pressurize water to 5-7Mpa or higher through the host water pump, and then transport the water to the rotary spray head installed on the pile pole through the pipeline system, and then spray it out through the high-pressure atomization nozzle on the head. The process of water mist dust suppression can be briefly described as:

[0004] Within the coverage area of ​​the water mist, the high-speed flowing water mist can collide and combine with the dust particles due to Brownian motion, and the particles will fall down due to their own weight and cannot be lifted up again;

[0005] The high-speed flowing water mist particles attract the dusty air around them into the range of the water mist and settle;

[0006] The settled dust particles are moist and sticky, and are not easy to fly, thus achieving a continuous dust suppression effect.

[0007] However, in the control of high-altitude dust, traditional fog piles are limited by the height of the installation pile and the convenience of transportation. The rotary spray head is generally installed on the pile with a concrete foundation on the horizontal ground beside the outdoor road or in the industrial and mining enterprise park. The pile is usually controlled within 15 meters and uses a whole single-section fixed-length steel structure rod or a multi-section welded fixed-length steel structure rod. During installation and construction, large-scale lifting equipment is often required for hoisting operations due to the long length of the pile, which has high construction costs and brings corresponding risks of high-height hoisting operations.

[0008] Meanwhile, the rotating spray head generally uses a servo motor or a stepper motor as the power component. In the dust control of industrial and mining enterprises with a lot of dust, such as steel, coking, and cement industries, methods such as visual linkage, dust linkage, and grayscale recognition linkage based on machine vision are mostly adopted to achieve precise control. However, for the rotating spray head installed on a fixed-height pile pole, the installation height is fixed, the spraying range is generally fixed, and the average droplet size is also fixed. Once it is manufactured and installed on the pile pole at a fixed height, it cannot adjust the spraying height during the spraying of the head according to actual needs, which will affect the spraying range and the dust suppression effect of the droplets scattered on the ground, and cannot meet the requirements of precise dust control. In addition, due to the limitation of its own structure, the rotating spray head cannot be installed on the top of a building or equipment, and even less can be suspended on the top of a material shed, making its application scenario relatively single. Moreover, the traditional fog pile for high-altitude dust control usually comes with a main unit. In order to provide a continuous and stable pressure water source for the rotating spray head installed on the fixed-height pile pole, while the main unit draws water from the main water supply pipeline of the factory and mining enterprise, it usually has a water tank with a certain capacity. The water tank is equipped with a low-water-level sensor, a float switch, and various valve joints are added. Coupled with electrical components such as the electronic control system display screen and controller arranged on the main unit, the whole main unit appears to be relatively bulky. When the main unit is usually standing beside the pile pole to supply water to the rotating spray head, it often occupies a large amount of space, which is not conducive to the rational use of the factory area space and the convenient entry and exit of vehicles, materials, and personnel.

[0038] Compared with the prior art, the present invention has the following beneficial technical effects:

[0039] 1. By adopting a multi-functional rotary nozzle, it can not only be vertically installed on the pile rod through conventional bolts, but also be hung and installed on the top frame girder of the material shed through bolts or steel wires. Moreover, it can be installed on the top of the building through anchor bolts or connected to other fixed equipment through bolts, greatly improving the application scenarios and scope of the dust suppression device;

[0040] 2. By adopting a multi-stage telescopic support column, the rotary nozzle is installed on the support column. The telescopic height of the installation can be adjusted in real time according to the instructions issued by the video and dust concentration detection linkage electronic control system to adjust the telescopic length of the telescopic pile rod, so as to achieve precise treatment of dust with different heights in the airspace by the rotary nozzle installed on the support column. At the same time, when the support column is adjusted to a higher position, large-flow nozzles can be used, and when the support column is adjusted to a lower position, small-flow nozzles can be used, so that the spray range and the average particle size of the fog can be adjusted, improving the dust treatment effect. Moreover, when the support column is in place after telescoping, its physical length is short, which is convenient for transportation. At the same time, large-tonnage lifting equipment is no longer required. Conventional electric forklifts can be used for safe and reliable hoisting construction at a lower height, reducing the installation construction cost and avoiding the potential risks of high-altitude hoisting operations;

[0041] 3. The high-altitude jet dust suppression device is equipped with a pipeline system. It abandons the conventional structure that uses an attached water tank for transitional water storage to ensure stable water inlet pressure of the water pump, and saves the water tank. A pressure stabilizing tank is directly set at the front end of the water inlet pipeline, which reduces the impact of water hammer effect on pipeline devices. Combined with the use of a water inlet pressure switch of the water pump, when the water pressure in the main water supply pipeline is too low, the high-pressure water pump is shut down for protection. The pressure stabilizing tank stabilizes pressure and absorbs energy, protecting the water circuit system and extending the service life of the high-pressure water pump motor. At the same time, the cancellation of the water tank makes the structural layout more spacious and reasonable, reduces the physical volume of the overall box shape, and makes the structure more compact. When it is used to supply water to a vertical rotating nozzle beside the support column or to a rotating nozzle suspended on the top of the material shed inside the material shed, the physical space occupied by the pipeline system is greatly reduced at this time, which is also more conducive to the convenient entry and exit of vehicles, materials, and personnel.

[0066] Embodiment 1

[0067] As Figures 1-5 shown, a rotating nozzle disclosed in this embodiment mainly includes a first housing 1, a water inlet assembly, a nozzle assembly and a driving assembly. Among them, the water inlet assembly includes a first water inlet pipe 2, a rotary joint 3 and a hollow bearing rod 4, and the nozzle assembly includes a second housing 5 and a nozzle 6. In this embodiment, the first water inlet pipe 2 is a rubber hose, and the rotary joint 3 is a high-pressure rotary joint.

[0068] The first housing 1 is a cylindrical welded part with openings at both ends. Among them, the top end of the first housing 1 is fixedly connected with a mounting seat 7 by bolts, and the bottom end is welded with an annular flange 8. Four equally distributed mounting holes are opened on the annular flange 8 for mounting the first housing 1 on a waiting installation plane such as a support column, a cantilever, or a building. Among them, when the annular flange 8 is installed on the waiting installation plane by threads, a cylinder cover plate 9 is also provided between the annular flange 8 and the waiting installation plane for capping, and a rubber pad 10 is additionally installed between the annular flange 8 and the cylinder cover plate 9.

[0069] One end of the first water inlet pipe 2 is located outside the first housing 1, and the other end is located inside the first housing 1. Specifically, the top end of the first housing 1 is provided with a first opening, and the side part of the first housing 1 is provided with a second opening. The end of the first water inlet pipe 2 passes through the first opening or the second opening and then is located inside the first housing 1. And waterproof joints 11 are arranged on both the first opening and the second opening, so that the waterproof joints 11 and the rubber pad 10 jointly ensure the sealing inside the first housing 1, isolating water, dust and other foreign matters from entering the first housing 1. Among them, the first opening and the second opening are provided to provide multiple water inlet routes according to the specific use conditions of the rotary sprinkler. For example, when the first housing 1 is hoisted on the top frame girder of a material shed or other building equipment, the first water inlet pipe 2 can enter the first housing 1 through the second opening and the waterproof joint 11 on the side part of the first housing 1. When the first housing 1 is installed on the top of a hollow support column, the first water inlet pipe 2 can enter the first housing 1 through the hollow support column, the first opening and the waterproof joint 11.

[0070] The rotary joint 3 is arranged vertically inside the first housing 1. There is a joint support 12 inside the first housing 1. One end of the joint support 12 is fixedly connected to the bottom of the mounting seat 7 by bolts, and the other end extends downward and is fixedly connected to the rotary joint 3, realizing the installation and fixation of the rotary joint 3 inside the first housing 1.

[0071] The bottom end of the rotary joint 3 is fixedly connected to the end of the first water inlet pipe 2 located inside the first housing 1, and the top end of the rotary joint 3 is rotatably connected to the bottom end of the hollow bearing rod 4. The hollow bearing rod 4 and the rotary joint 3 are coaxially arranged. A flange bearing 13 is also fixedly installed at the bottom of the mounting seat 7 by bolts, and the mounting seat 7 has a first through hole coaxial with the hollow bearing rod 4. The top end of the hollow bearing rod 4 passes through the flange bearing 13 and the first through hole in sequence and then is located outside the first housing 1. Among them, the hollow bearing rod 4 is in interference fit with the inner ring of the flange bearing 13 and in clearance fit with the hole wall of the first through hole, thereby realizing the rotational connection between the hollow bearing rod 4 and the first housing 1.

[0072] The bottom end of the second housing 5 is provided with a second through hole coaxial with the hollow bearing rod 4, so that after the top end of the hollow bearing rod 4 passes through the first through hole, it continues to pass through the second through hole and is located inside the second housing 5, and the hollow bearing rod 4 is fixedly connected to the second housing 5. Specifically, the hollow bearing rod 4 can be fixedly connected to the second housing 5 by an interference fit with the hole wall of the second through hole, or directly by welding or fastening bolts.

[0073] The side of the second housing 5 has a third through hole. The water outlet end of the nozzle 6 is located outside the second housing 5, and the water inlet end of the nozzle 6 passes through the third through hole and is located inside the second housing 5, and the nozzle 6 is fixedly connected to the second housing 5. Specifically, the nozzle 6 can be fixedly connected to the second housing 5 by an interference fit with the hole wall of the third through hole, or directly by welding or fastening bolts. Inside the second housing 5, there is a horizontally arranged nozzle mounting pipe 14. One end of the nozzle mounting pipe 14 is fixedly connected to the water inlet end of the nozzle 6, and the other end is connected to the top end of the hollow bearing rod 4 through a right-angle elbow 15.

[0074] The drive assembly is arranged inside the first housing 1 and is in transmission connection with the hollow bearing rod 4 to drive the hollow bearing rod 4 to rotate. Specifically, the drive assembly includes a first servo motor 16, a driving wheel 17, a driven wheel 18 and a first transmission mechanism 19. Among them, the first servo motor 16 is fixedly connected to the bottom of the mounting seat 7 by bolts, and the rotation output end of the first servo motor 16 is vertically downward. The driving wheel 17 is fixedly connected to the rotation output end of the first servo motor 16 by means of screw fit or key connection or bolt fixation. The driven wheel 18 is fixedly sleeved on the hollow bearing rod 4 by means of screw fit or key connection or bolt fixation, and the driving wheel 17 and the driven wheel 18 are in transmission connection through the transmission mechanism. In the specific implementation process, the transmission structure can be a belt. Of course, the driving wheel 17 and the driven wheel 18 can also be set as sprockets, and the first transmission structure can be set as a chain. It is also possible to directly replace the driving wheel 17 and the driven wheel 18 with two meshing gears, that is, the driving effect can be achieved without setting a transmission mechanism.

[0075] The working process / operating principle of the above-mentioned rotary nozzle is as follows: Pressurized water flows from the main water inlet pipe to the rotary joint 3, then passes through the hollow bearing rod 4, the right-angle elbow 15, and the nozzle mounting pipe 14 to reach the nozzle 6 and is ejected through the nozzle 6. When the rotary nozzle receives a rotation instruction, the first servo motor 16 is energized to drive the driving wheel 17 to rotate, and the driven wheel 18 is rotated through the transmission mechanism synchronous belt. Since the mating section of the driven wheel 18 and the hollow bearing rod 4 passing through its center is in a tight fit or key connection, the driven wheel 18 drives the rotation of the hollow bearing rod 4, and further drives the second housing 5, the right-angle elbow 15, the nozzle mounting pipe 14, and the nozzle 6 installed at the top of the hollow bearing rod 4 to rotate together. The use of the rotary joint 3 ensures that when the hollow bearing rod 4 rotates, the water inlet pipe connected to the rotary joint 3 remains relatively stationary and does not twist or rotate. At the same time, the rotary joint 3 can not only be vertically installed on the pile rod through conventional bolts, but also be hung and installed on the top frame girder of the shed through bolts or wires, and can also be installed on the top of the building through anchor bolts or bolt-connected to other fixed equipment, greatly expanding the application scenarios and scope of the dust suppression device.

[0076] Embodiment 2

[0077] As Figures 6-14 shown, a multifunctional high-altitude rotary jet dust suppression device disclosed in this embodiment includes the rotary nozzle in Embodiment 1 and a support column 49. The annular flange 8 at the bottom end of the first housing 1 in the rotary nozzle is fixedly connected to the top of the support column 49 through bolts.

[0078] As a preferred implementation, the support column 49 can be set as a telescopic column. When the rotary nozzle is installed on the support column 49, the telescopic height of the installation can be adjusted in real time according to the instructions issued by the video and dust concentration detection linkage electronic control system to adjust the telescopic length of the telescopic pile rod, so as to achieve precise control of dust in different height airspaces by the rotary nozzle installed on the support column 49. At the same time, when the support column 49 is raised, large-flow nozzles 6 can be used, and when the support column 49 is lowered, small-flow nozzles 6 can be used, so that the spray range and the average particle size of the mist can be adjusted, improving the dust control effect. Moreover, when the support column 49 is in place after telescoping, its physical length is short, which is convenient for transportation. At the same time, large-tonnage lifting equipment is no longer required, and conventional electric forklifts can be used to safely and reliably hoist and construct at a lower height, reducing the installation and construction cost while avoiding the potential risks of high-altitude hoisting operations.

[0079] In the specific implementation process, the support column 49 realizes the adjustable telescopic length of the pile rod through the form of a servo motor driving a lead screw-nut pair + a wire rope pulley group, and further realizes the adjustable installation height of the rotary nozzle when it is vertically installed. Specifically, it includes a second servo motor 20, a lead screw 21, a lead screw nut 22, a first wire rope 23, a second wire rope 24, and a hollow first arm 25, second arm 26, and third arm 27. In this embodiment, the first arm 25, second arm 26, and third arm 27 are all square tube structures, and they can also be set as circular tube structures or polygonal structures in application.

[0080] The bottom end of the first arm 25 is provided with an installation structure 28, such as a flange edge and bolt holes, etc., and thus the first arm 25 can be installed on the foundation by means of bolt fixation. The top end of the first arm 25 is welded or bolt-connected with a first top plate 29, and a first through hole is opened on the first top plate 29. The bottom end of the second arm 26 is located inside the first arm 25, and the top end of the second arm 26 passes through the first through hole and is located outside the first arm 25, and there is a first gap between the inner wall of the first arm 25 and the outer wall of the second arm 26. The bottom end of the second arm 26 is welded or bolt-connected with a mounting plate 30, and the top end of the second arm 26 is welded or bolt-connected with a second top plate 31, and a second through hole is opened on the second top plate 31. The bottom end of the third arm 27 is located inside the first arm 25, and the top end of the third arm 27 passes through the second through hole and is located outside the second arm 26, and there is a second gap between the inner wall of the second arm 26 and the outer wall of the third arm 27. The annular flange 8 at the bottom end of the first housing 1 in the rotary nozzle is fixedly connected to the top end of the third arm 27 by means of bolt fixation.

[0081] The second servo motor 20 is fixedly installed on the mounting plate 30 by means of bolts, and the rotary output part of the second servo motor 20 is located inside the second arm 26. The lead screw 21 is located inside the second arm 26 and is fixedly connected to the rotary output end of the second servo motor 20 through a coupling. The lead screw nut 22 is fixedly arranged at the bottom end of the third arm 27 by means of bolt connection or welding and is thread-connected with the lead screw 21. At the same time, the third arm 27 is sleeved on the lead screw 21.

[0082] On both sides of the bottom end of the mounting plate 30, symmetric first guide wheels 33 are rotatably arranged through first wheel frames 32 respectively. On both sides of the top end of the second top plate 31, symmetric second guide wheels 35 are rotatably arranged through second wheel frames 34 respectively, and the first guide wheels 33 correspond to the second guide wheels 35. At the same time, both the first steel wire rope 23 and the second steel wire rope 24 are two in number and correspond to the first guide wheels 33 and the second guide wheels 35. That is, the first guide wheels 33, the second guide wheels 35, the first steel wire rope 23 and the second steel wire rope 24 on the same side form a set of connection structures. In the same set of connection structures, one end of the first steel wire rope 23 is fixedly connected to the corresponding side of the top end of the lead screw nut 22, and the other end sequentially passes through the second gap, the second top plate 31, the corresponding second guide wheel 35 and then is fixedly connected to the corresponding side of the top end of the first top plate 29; one end of the second steel wire rope 24 is fixedly connected to the corresponding side of the bottom end of the lead screw nut 22, and the other end sequentially passes through the mounting plate 30, the corresponding first guide wheel 33, the first gap and then is fixedly connected to the corresponding side of the bottom end of the first top plate 29. Specifically:

[0083] One end of one of the first steel wire ropes 23 is fixedly connected to one side of the top end of the lead screw nut 22, and the other end sequentially passes through the gap between the second arm 26 and the third arm 27, the second top plate 31, one of the second guide wheels 35 and then is fixedly connected to one side of the top end of the first top plate 29; one end of one of the second steel wire ropes 24 is fixedly connected to one side of the bottom end of the lead screw nut 22, and the other end sequentially passes through the mounting plate 30, one of the first guide wheels 33, the gap between the first arm 25 and the second arm 26 and then is fixedly connected to one side of the bottom end of the first top plate 29;

[0084] One end of the other first steel wire rope 23 is fixedly connected to the other side of the top end of the lead screw nut 22, and the other end sequentially passes through the gap between the second arm 26 and the third arm 27, the second top plate 31, the other second guide wheel 35 and then is fixedly connected to the other side of the top end of the first top plate 29; one end of the other second steel wire rope 24 is fixedly connected to the other side of the bottom end of the lead screw nut 22, and the other end sequentially passes through the mounting plate 30, the other first guide wheel 33, the gap between the first arm 25 and the second arm 26 and then is fixedly connected to the other side of the bottom end of the first top plate 29.

[0085] As a preferred embodiment, on both sides of the inner wall of the first arm 25, first guiding grooves extending vertically are symmetrically provided. On the outer wall of the second arm 26, two first guiding blocks 52 corresponding to the first guiding grooves are provided. One end of the first guiding block 52 is fixedly connected to the second arm 26 by welding, and the other end is embedded in the first guiding groove and slidably engaged with the first arm 25. On both sides of the inner wall of the second arm 26, second guiding grooves extending vertically are symmetrically provided. On the outer wall of the third arm 27, two second guiding blocks 50 corresponding to the second guiding grooves are provided. One end of the second guiding block 50 is fixedly connected to the third arm 27, and the other end is embedded in the second guiding groove and slidably engaged with the second arm 26. Further preferably, a mechanical limiting block is also connected to the bottom of the first guiding groove by bolts, for mechanical limiting when the second arm 26 retracts in place and anti-drop protection under extreme working conditions.

[0086] As a preferred embodiment, a maintenance window sealing plate 54 is provided at the bottom of the first arm 25, for sealing the maintenance window at the bottom of the first arm 25 during normal operation when not under maintenance, and only the maintenance window waterproof joint 55 installed thereon is retained, for the electrical control wiring of the second servo motor 20.

[0087] The telescoping process / retraction of the above-mentioned support column 49 is as follows: when the second servo motor 20 is powered on and rotates clockwise, it drives the lead screw 21 to rotate through the coupling, and then drives the lead screw nut 22 to move upward, and then drives the third arm 27 and the rotary sprinkler head installed on the upper part of the third arm 27 to move upward. Since two second guiding blocks 50 are symmetrically welded on the outer side of the lower part of the third arm 27, the second guiding blocks 50 ensure that the third arm 27 slides reliably along the second guiding grooves arranged in the inner arm of the second arm 26 under the transmission of the lead screw nut 22 pair. At the same time, since two first guiding blocks 52 are symmetrically welded on the outer side of the lower part of the second arm 26, the first guiding blocks 52 ensure that the second arm 26 slides along the first guiding grooves arranged in the first arm 25 synchronously when the third arm 27 expands and contracts. When the third arm 27 moves upward and extends under the transmission of the lead screw nut 22 pair, through the traction of a total of four steel wires, namely two first steel wires 23 and two second steel wires 24, both of which are fixed to the lead screw nut 22 at one end, and the first guiding wheel 33 and the second guiding wheel 35, the second arm 26 will move upward and extend synchronously with the third arm 27. On the contrary, when the second servo motor 20 is powered on and rotates counterclockwise to the in-place position, it synchronously retracts to the shortest state. At this moment, the physical length of the support column 49 is the shortest, which is convenient for transportation. At the same time, large-tonnage hoisting equipment is no longer required, and a conventional electric forklift can safely and reliably hoist at a lower height. The installation structure 28 of the first arm 25 on the outermost side of the support column 49 can be reliably installed on the concrete foundation with the embedded anchor bolts inserted, which is convenient for installation, reduces the installation construction cost, and avoids the potential risks of high-altitude hoisting operations. It should be noted that in other embodiments, the support column 49 can also adopt different transmission structural forms such as a synchronous belt linear module, an electric push rod, a rack and pinion, a sprocket chain, or a hydraulic cylinder to achieve multi-stage telescopic linear motion.

[0088] In the specific implementation process, the multi-functional high-altitude jet dust suppression device further includes a pipeline system, which includes a box body 36 and a second water inlet pipe 37, a high-pressure water pump 38, a return water rubber hose 39 and a drain pipe 40 provided on the box body 36. One end of the second water inlet pipe 37 is connected to an external water source, and the other end is connected to the water inlet end of the high-pressure water pump 38 through a water inlet rubber hose 41. The water outlet end of the high-pressure water pump 38 is connected to the first water inlet pipe 2 through a water outlet rubber hose 42. Among them, a pressure stabilizing tank 43, a filter 44, a water pump inlet pressure switch 45 and a water inlet solenoid valve 46 are successively provided on the second water inlet pipe 37. One end of the return water rubber hose 39 is connected to the water outlet end of the high-pressure water pump 38, and the other end is communicated with the water inlet end of the water inlet rubber hose 41. One end of the drain pipe 40 is connected to the water outlet end of the high-pressure water pump 38, and the other end extends vertically downward outside the box body 36. A drain solenoid valve 47 is provided on the drain pipe 40.

[0089] In this embodiment, the second water inlet pipe 37 is composed of a first water inlet steel pipe, a second water inlet steel pipe, a third water inlet steel pipe, and multiple reducing tee female connectors, union joints, and elbows. The pressurized water taken from the water intake point of the main water supply pipe of factories and mines is connected to the first water inlet steel pipe. The first water inlet steel pipe is connected to the second water inlet steel pipe through a reducing tee female connector. The second water inlet steel pipe is connected to the water inlet of the filter 44 through a union joint. The water outlet of the filter 44 is connected to the third water inlet steel pipe through a union joint, a reducing tee female connector, and a water pump inlet pressure switch 45. The third water inlet steel pipe is supported and fixed by a water pipe fixing bracket on the box body 36. The other end of the third water inlet steel pipe is connected to a water inlet solenoid valve 46. The outlet of the water inlet solenoid valve 46 is connected to the water pump inlet rubber hose 41 through a DN25 right-angle elbow and a reducing tee female connector. The pressurized water in the water pump inlet rubber hose 41 drives the high-pressure water pump 38 to rotate and pressurize it, and is discharged through the water outlet rubber hose 42 and then sprayed out through the nozzle 6 after being delivered to the rotary nozzle. During this process, the return water rubber hose 39 is used to connect and discharge the excess pressurized water at the outlet of the high-pressure water pump 38 to the water pump inlet rubber hose 41 for water replenishment. When the pressure of the water inlet pipe is insufficient or there is a water shortage, the water pump inlet pressure switch 45 cannot be opened, which avoids the water shortage operation of the high-pressure water pump 38. When the rotary nozzle stops working, the drain electric ball valve is energized and opened, and the residual water in the rotary nozzle, whether it is a vertical multi-stage telescopic pile rod or a rotary nozzle suspended on the top beam of the shed, together with the pipeline system, is discharged through the drain pipe 40. This pipeline system does not have a water tank. A pressure stabilizing tank 43 is directly set on the reducing tee female connector between the first water inlet steel pipe and the second water inlet steel pipe to reduce the impact of water hammer effect on the filter 44 and corresponding valves and the high-pressure water pump 38 on the pipeline. Combined with the use of the water pump inlet pressure switch 45, the water pump is protected from shutdown when the water pressure of the main water supply pipe is too low. The pressure stabilizing tank 43 stabilizes pressure and absorbs energy, protecting the water pipeline system and extending the service life of the water pump motor 51. At the same time, the cancellation of the water tank makes the internal structure layout of the box body 36 more abundant and reasonable. The overall physical volume of the box body 36 is reduced, and the structure is compact. When supplying water to the vertical multi-functional rotary nozzle head installed beside the pile rod or the multi-functional rotary nozzle head suspended on the top of the shed inside the shed, the physical space occupied by the main machine is greatly reduced at this time, which is also more conducive to the convenient entry and exit of vehicles, materials, and personnel. It should be noted that the control logic for realizing the above working process can be achieved through the PLC controller installed in the box body 36. The specific process is a conventional means in the relevant field, so it will not be elaborated in this embodiment.
