Fire extinguishing with water is the most convenient and economical implementation in the fire-fighting field, and buildings generally require a corresponding configuration of hydrant ports for fire-extinguishing water. However, with the development of cities, the buildings are more and more dense, and the difficulty of high-rise fire extinguishment is continuously improved. The main reason is that the water pressure required for high-rise fire extinguishment is high, and correspondingly, a stronger water pressure source is required to be provided, but fire hydrants matched with buildings are not provided with the stronger water pressure source, so that the fire hydrants are technical reasons on one hand, and economic reasons on the other hand.

In general, when spraying water to a low-rise area of a building, a hydrant water source may be directly used, and when spraying water to a middle-high rise to extinguish a fire, a booster pump or a relay pump is generally added between an end fire sprinkler and a fixed hydrant water source in order to enable water flow to reach a fire point. In the prior art, in order to obtain better supercharging effect, a high-power engine is generally used, so that the booster pump is large in size and heavy in mass, noise is large during operation, fuel consumption is high due to large power, and the on-site fire extinguishing work is affected by oiling at intervals when needed. And the existing high-power engine and pump body are all irregularly shaped, and after being integrated together, the whole system is huge in volume and inconvenient to transport and deploy, and brings adverse effects to fire control.

In the prior art, in order to meet the pressure requirement of terminal fire extinguishing facilities, the power of a general engine is larger, the oil consumption is higher, and particularly in the application scene of fire extinguishing, the booster pump is required to be rapidly deployed and the fire extinguishing work is required to be implemented, so that the weight and the volume of the booster pump and the supporting facilities are correspondingly limited. Under the comprehensive effects of high oil consumption, small volume and light weight, the oil tank is designed to be relatively small in the existing booster pump and the matched facility system, and in continuous fire extinguishment, uninterrupted fuel oil replenishment is required, and in specific operation, one mode is stop oiling and the other mode is non-stop oiling.

Wherein, the stopping and oiling mode can inevitably lead to the output interruption of the booster pump, thereby bringing negative influence to the fire control; in the non-stop refueling mode, because the gasoline has the characteristic of being volatile, when the gasoline is refueled in an opening way, after the gasoline volatilizes into the air and contacts with sparks of a high-temperature engine and an exhaust system, dangers can be possibly caused, particularly in a fire scene, inflammable and explosive objects are isolated, and the volatile fuel can be directly exposed to the air by frequent refueling, so that the potential safety hazard on the scene is seriously increased.

In order to provide enough supercharging performance, the volumes of the engine and the pump body are larger, the engine and the pump body shell are in irregular shapes, a large amount of space is occupied after the engine and the pump body are integrated on the support, the space utilization rate of the engine is low, the power consumption of the engine is high, the capacity requirement on the oil tank is high in order to improve the continuous output capacity, and if a regular large oil tank is additionally arranged, the volume of the whole self-adaptive fire-fighting supercharging system is greatly enlarged.

In this embodiment, make full use of original space combines engine and pump body molding special characteristics that lead to space utilization low, designs the oil tank into a plurality of parts, and the inside cavity holds the partial structure of pump body and engine, and outside forms regular planar structure, makes whole system deposit and transportation more convenient, also is convenient for hold in the fire control vehicle to send to the scene fast, provide continuous output.

In particular, improvements in construction and connection are included. Referring to fig. 4 and 5, the multiple tank units are designed independently and installed in a modularized manner, and in the simplest embodiment, the system only includes one tank unit, i.e. the first tank unit 1031, where the pump body 13 and the engine 11 are located at two sides of the first tank unit 1031, the first tank unit 1031 is provided with a through hole 10311, and the coupling 12 just penetrates through the through hole 10311 to connect the power of the pump body 13 and the power of the engine 11. In this embodiment, through the special layout scheme of the pump body 13, the engine 11, the first oil tank 1031 and the coupling 12, the engine 11 is fully utilized to be of a special-shaped structure and has a larger volume, and the pump body 13 has a larger expansion volume because of being connected with the water inlet pipe and the water outlet pipe, but the coupling 12 connecting the two has the characteristic of smaller diameter, the first oil tank 1031 is arranged between the pump body 13 and the engine 11, and the through hole 10311 is arranged on the first oil tank 1031, so that the coupling 12 passes through, and on the basis of not increasing the occupation of the whole space of the system, each component is skillfully laid, the structural characteristics of each component are fully utilized, the integration of the system is increased, the volume of the system is reduced, convenience is brought to the storage, transportation, deployment and the like of the whole system, and the method has great significance to the rapid rescue of emergency scenes.

On the basis of the first oil tank portion 1031, the second oil tank portion 1032 may be further installed in a modularized manner, the second oil tank portion 1032 makes full use of the structure of the water pump, specifically, the tail portion of the water pump is connected with the engine 11, the first oil tank portion 1031 is installed on the side, the water inlet end and the water outlet end of the water pump occupy one side end and the opposite end of the second oil tank portion 1032 substantially, but the opposite side of the main water outlet pipe 132 of the water pump is relatively simple, no water pipe and other structures are provided, the second oil tank portion 1032 is arranged on the side, and the second oil tank portion 1032 may have a relatively regular structure, so that the space is fully utilized.

In connection, referring to fig. 6, the first tank portion 1031 and the second tank portion 1032 are provided with fuel for the engine 11 through two lines, respectively, which are independently controllable through two-way interlock valves 1038. When the system is provided with the first oil tank part 1031, the system can still normally operate, and the light weight, the light weight and the convenient deployment can be realized to the greatest extent; after the system adds the second oil tank portion 1032, the two oil tank portions can be backed up each other, when one oil tank is filled, the other oil tank can supply oil for the engine, the engine is prevented from being filled while working or stopped, in addition, the second oil tank portion 1032 also doubles the endurance of the system, and the continuous output capability of the fire extinguishing system can be improved. On this basis, two-way interlock valves 1038 can also be used to cooperate to drain fuel from the tank, if desired.

In this embodiment, the main reason that the water pump is in a special-shaped structure and occupies a larger space is that the main water inlet pipe 131 and the main water outlet pipe 132 have the requirement of extending direction, but the volume of the water pump body is relatively smaller, and the axes of the water pump body, the main water inlet pipe 131 and the main water outlet pipe 132 are almost located on the same horizontal plane, that is, the water pump occupies a larger space mainly in the extending direction of the main water inlet pipe 131 and the main water outlet pipe 132, and the occupied space of the upper side and the lower side of the water pump is smaller, in the prior art, the upper side space of the water pump is almost unavailable, and the volume of the oil tank is greatly increased after the oil tank is additionally arranged. In this embodiment, the third oil tank portion 1033 is disposed on the pump body 13, the first oil tank portion 1031 and the second oil tank portion 1032, and is further configured by utilizing structural features of system components, so that space utilization is effectively improved, oil tank capacity is increased, and continuous output capability of the system is improved.

And the third oil tank portion 1033 realizes hot plug quick docking and dismounting with the first oil tank portion 1031 and the second oil tank portion through the quick plug sealing connector 1035, so that the deployment efficiency of the fire pump system is greatly facilitated. The quick-connect sealing joint 1035 is characterized in that when the quick-connect sealing joint 1035 matched with two ends is connected in a butt joint mode, two parts of the butt joint form a communication loop, when the butt joint ends are pulled out and separated, the two ends can be automatically sealed, and the quick-connect sealing joint 1035 belongs to the prior art and is not described in detail herein. In the above embodiment, three tank portions are modularly installed, and only the first tank portion 1031 may be added, then the second tank portion 1032 may be added, and then the third tank portion 1033 may be added. The volume is reduced, and the installation is carried out according to the need; the first tank portion 1031 and the second tank portion 1032 may be backed up to each other, so that the refueling is performed without stopping; the third oil tank portion 1033 is located the top, adopts quick plug connected mode, can demolish fast, leaves more maintenance spaces, and convenient maintenance and connection pump body pipeline.

When the third tank portion 1033 is installed, the two-way interlock valve 1038 is closed, and at this time, the oil passage 10382 of the two-way interlock valve 1038 is closed, and the air pressure passage 10381 is opened. If the third tank portion 1033 is empty, the air pressure of the third tank portion 1033 and the lower tank will be automatically balanced; if the third oil tank 1033 has oil, the pressure between the upper and lower oil tanks needs to be balanced automatically by the air pipe due to the gravity of the oil, and the oil in the third oil tank 1033 at the upper part can enter the oil tank at the lower part automatically; after the upper tank is installed, the two-way interlock valve 1038 may be opened to supply the engine with oil.

Referring to fig. 7, the two-way interlock valve 1038 includes an air pressure channel 10381 and an oil channel 10382, which are interlocked, and are switched by a switching lever 10383, wherein when one of the two channels is opened, the other channel is closed. The air pressure balance pipe 1037 and the air pressure channel 10381 are matched, when the oil liquid channel 10382 is closed, the air pressure channel 10381 is opened, air pressure balance is formed between the upper oil tank and the lower oil tank, and the oil in the upper oil tank can be added into the lower oil tank; when the oil passage 10382 of the two-way interlock valve 1038 is open, the oil passage 10382 is open, the air pressure passage 10381 is closed, and at this time, when the lower tank is consumed, the upper third tank portion 1033 automatically supplements the lower tank, and the two tanks are substantially connected together. In this case, when the oil in the lower tank is not consumed, even if the lower tank has a small amount of oil and the upper tank has oil, the oil in the upper tank does not automatically flow into the lower tank, so that the amount of oil in the lower tank can be controlled as needed, and the lower tank is not always filled with the upper tank. Specifically, the oil passage 10382 of the two-way interlock valve 1038 is closed, the oil supply to the engine is cut off, the air pressure passage 10381 is opened, the upper tank starts to fill the lower tank, and the two-way interlock valve 1038 is switched in time to stop the filling to maintain the lower tank capacity, and the fuel supply mode is entered.

At the same time as the internal gas pressures of the plurality of tank sections are balanced, the oil and gas filter 1036 is also balanced with the external atmosphere. The oil gas filter 1036 can filter the oil gas in the air, when the engine absorbs oil or the pressure difference is formed between the inside of the oil tank and the outside atmosphere due to the volatilization of the oil gas in the oil tank, the gas can enter or leave the oil tank through the oil gas filter 1036, and meanwhile, the oil gas filter 1036 can filter the oil gas volatilized and mixed in the gas to prevent the oil gas from overflowing to the outside, so that the waste is avoided, and the additional potential safety hazard brought to the fire extinguishing work is avoided.

Referring to fig. 2, 4 and 6, the present embodiment further includes an external oil tank 1034, where the external oil tank 1034 includes an elastic diaphragm 10341, a water filling port 10342, an oil filling port 10343 and an oil outlet, the elastic diaphragm 10341 divides the interior of the external oil tank 1034 into an oil storage area and a water storage area, the water filling port 10342 is disposed on the upper portion of the water storage area, the oil filling port 10343 and the oil outlet are respectively disposed on the upper portion and the lower portion of the oil storage area, and the oil outlet is connected to the third oil tank 1033 and supplies oil thereto.

In the previous embodiment, one of the important improvements is to modularly design and layout the oil tank according to the structural shapes of the engine and the water pump, the arrangement requirements of water inlet and outlet pipes and the like, fully develop the space utilization rate on the premise of not increasing the original space occupation of the system, increase the capacity of the oil tank, improve the cruising ability of the fire pump system, and simultaneously enable the appearance of the whole fire pump system to be more regular from special shapes; the surrounding type and detachable design of the multiple oil tanks is convenient to overhaul and deploy.

However, even if the capacity of the fuel tank is limited, it is difficult to meet the continuous high power output in some fire extinguishing scenarios, in this embodiment, the external fuel tank 1034 may provide continuous fuel supply for the system, and the external fuel tank 1034 may be transported and stored independently of the system, so that a large volume and a large capacity may be achieved. When oil supply is needed, water can be guided from the main water outlet pipe 132, water flow enters the water storage area, the pressure of the water flow presses the elastic diaphragm 10341, the elastic diaphragm 10341 expands and presses the oil storage area, oil in the oil storage area enters the third oil tank portion 1033 under pressure, and air in the third oil tank portion 1033 is discharged to the outside through the oil gas filter 1036, so that continuous oil supply and oil tank pressure balance are achieved.

Compared with the prior art, the scheme has the advantages that the oil can be continuously supplied from the external large oil tank, and oil liquid cannot contact with air and volatilize into the air of a fire scene when the oil is supplied; in addition, the oil tank is not required to be lifted or an oil pump is not required to be used during oiling, the water outlet pressure of the main water outlet pipe 132 is directly utilized as power, continuous and non-volatile oiling is realized, and when fire is extinguished, the materials are taken locally, the implementation is convenient, and powerful guarantee is provided for fire extinguishing work.

Further, referring to fig. 11, the present embodiment further includes a direct cooling system 14;

the direct cooling system 14 includes a cooling inlet pipe 143 and a cooling outlet pipe 142;

the cooling water inlet pipe 143 is used for leading water from the water outlet end of the pump body 13 and flows into the engine 11;

one end of the cooling water outlet pipe 142 is connected to a cooling water outlet of the engine 11, and the other end is connected to a water inlet end of the pump body 13.

In specific implementation, the cooling water pipe can be arranged at the water outlet or the water inlet of the pump body, and can also be arranged on the water outlet pipe and the water inlet pipe of the pump body, and the cooling water pipe is basically the same.

When the pump is in a working state, the pressure at the main water outlet pipe is larger than the pressure at the main water inlet pipe, at the moment, liquid pressure difference is formed at the two ends of the cooling loop, water automatically enters the cooling loop from the main water outlet pipe and flows through the engine, then flows back to the main water inlet pipe from the cooling water outlet pipe, so that the cooling loop is formed, the cooling water is continuously supplied to the engine for heat exchange, the cooling water flow can be automatically regulated according to the power of the engine, namely, the pressure difference at the two ends of the main water outlet pipe and the main water inlet pipe, and the larger the power is, the larger the pressure difference is, and the more the flow of the cooling water is. The cooling circuit of this mode simple structure just goes on voluntarily completely, can also be according to engine power automatically regulated, and the reliability is high, with low costs, and heat transfer effect is good.

As a further aspect of this embodiment, a throttle valve 141 may be provided in the cooling circuit as a flow control means for controlling the flow rate of the cooling liquid, which has the effect of reducing the loss of the main boost circuit. Specifically, when the pressure difference between the water outlet and the water inlet of the pump is large, the flow rate of the cooling circuit is correspondingly large, and even the flow rate of the cooling circuit can far exceed the actual cooling water flow rate required by the engine, and if the flow rate is not limited, the loss of the main circuit is excessively increased.

Alternatively, this embodiment also provides another cooling mode, referring to fig. 12, including an indirect cooling system 15;

the indirect cooling system 15 includes a heat exchanger 152, an internal circulation loop 153, a circulation pump 154, and an external circulation loop 155;

the circulation pump 154 is located in the internal circulation circuit 153 and provides power to the internal circulation circuit 153;

both the inner circulation loop 153 and the outer circulation loop 155 flow through the heat exchanger 152 and exchange heat within the heat exchanger 152;

the inner circulation circuit 153 also flows through the engine 11 and takes heat from the engine 11;

the external circulation loop 155 draws water from the water outlet end of the pump body 13, flows through the heat exchanger 152, exchanges heat, and then flows out to the water inlet end of the pump body 13.

In the indirect cooling mode, the cooling liquid in the engine does not participate in the circulation of the fluid in the pump body, the flowing power of the cooling liquid in the engine is provided by the circulating pump, and the power of the external circulation is the same as that of the previous embodiment. The external water source of the embodiment does not enter the engine, but exchanges heat through the two cooling liquid circulation loops, and the engine has the advantages of wider application range and simple maintenance.

Specifically, the internal circulation cooling loop of the engine is self-formed and flows in a closed mode, so that oil or special cooling liquid can be used, and compared with water, the cooling liquid can effectively prevent parts in the cooling loop device from corroding and rusting, plays a better protection role, and reduces the maintenance cost of the engine; on the other hand, the water flow of the external circulation loop does not enter the engine, so that sediment, microorganism algae and the like in water do not enter the engine in a fire extinguishing environment with poor water quality, and therefore, the water quality control device has wider application range and is almost not limited by the water quality.

As a further aspect of the present embodiment, a throttle valve two 151 may be provided in the outer circulation loop as a flow control means for controlling the flow rate of the coolant, which has the effect of reducing the loss of the main boost loop. Specifically, when the outlet water pressure and the inlet water pressure of the pump are greatly different, the flow rate of the cooling circuit is correspondingly large, and even the flow rate of the cooling circuit can far exceed the actual cooling water flow rate required by the engine, and if the flow rate is not limited, the loss of the main circuit is excessively increased.

Referring to fig. 8, the pump body 13 further includes a bypass shunt tube 133 and a diverter valve 134, wherein one end of the bypass shunt tube 133 is connected with the main water inlet tube 131, the other end is connected with the main water outlet tube 132, and the diverter valve 134 is disposed at a connection position between the bypass shunt tube 133 and the main water inlet tube 131, for controlling inflow water at the main water inlet tube 131 to flow into the pump body 13 or flow into the bypass shunt tube 133.

In particular, the adaptive fire booster system is typically connected to the middle of a water pipe, specifically, one end of the water pipe is connected to a fixed hydrant, and the other end is connected to a terminal water spraying device, which provides a high pressure water source. In the fire extinguishing process, water needs to be sprayed to a high area and water needs to be sprayed to a low area, so that the required pressure of the tail end is generally dynamically changed.

In the above process, if the pressure of the fixed hydrant is sufficient, pressurization is not required, and at this time, the fire pump may be stopped or removed. However, in consideration of the urgency of the actual fire-extinguishing site and the dynamic nature of the water pressure requirement, the mode of dismantling the fire pump directly to the connecting water pipe is not advisable; on the other hand, if the fire pump is simply turned off or the water flow passes through the fire pump, both the blades in the pump and the engine connected with the blades become loads of the water flow, thereby losing the energy of the water flow; the fire pump can be kept running, but the energy consumption of the system can be improved, the energy consumption of the engine is high, the space of the oil tank is small, and the energy consumption saving is very important to improving the continuous output capacity of the fire pump.

In the embodiment, the bypass shunt pipe and the diversion valve effectively solve the problems, and when pressurization is needed, the bypass shunt pipe and the diversion valve are switched into a pump body loop; and when no boost is needed, switch to the bypass shunt loop. And the pressurizing and energy-saving effects are considered, the continuous output capacity of the fire pump is improved, and the loss of water pressure during bypass diversion is reduced.

Referring to fig. 10, the adaptive fire-fighting pressurizing system further includes a first pressure sensor 17, a second pressure sensor 18, a rotation speed sensor, and a controller 16;

the first pressure sensor 17 is located at the inlet of the main water inlet pipe 131, the second pressure sensor 18 is located at the water outlet end of the pump body 13, and the first pressure sensor 17 and the second pressure sensor 18 are used for detecting the fluid pressure at the positions;

the rotation speed sensor is positioned on the shaft of the coupler 12 and is used for detecting the rotation speed of the output shaft of the engine 11;

the controller 16 includes a wireless receiver and a plurality of electrical interfaces, the controller 16 is connected with the engine 11 through the electrical interfaces, so as to control the engine 11, and the wireless receiver is used for receiving control signals transmitted by a remote controller.

The adaptive fire-fighting pressurizing system of the embodiment comprises two working modes of pressurizing and bypass, and as to which mode is performed, the pressure needs to be comprehensively determined according to the water inlet pressure and the demand pressure of the water outlet end. The most primitive way is to manually sense the water pressure, switch to the bypass mode if the original water pressure is felt to be sufficient, and switch to the boost mode if the original water pressure is felt to be insufficient. This approach is indeed feasible in some situations, but when the pipeline is complex, particularly when the pipeline is not directly output, but is connected to another pipeline, such as a pipeline with multiple pressurization systems in the middle, the operator cannot sense the water pressure in the middle pipeline.

In this embodiment, add pressure sensor in booster pump both sides, obtain water pressure data by pressure sensor, more be convenient for judge the required mode that goes on of booster pump, simultaneously, collect water pressure data through the sensor mode, also more be convenient for monitor pipeline, pump body, intraductal condition etc., simplify pipeline return circuit maintenance and obstacle removal process.

When in a supercharging mode, the quantity of required supercharging is comprehensively determined according to the water pressure requirement of an output end and the actual water pressure of an input end, the specific supercharging effect is determined by the rotating speed of the engine, the higher the supercharging quantity is, the more the supercharging quantity is, the speed sensor is arranged on the shaft of the coupler, the rotating speed of the engine can be detected, the output state of the engine is obtained, a closed loop between the control parameter and the actual action effect is formed, the accurate control of the power and the rotating speed of the engine is facilitated, and the supercharging effect is adjusted.

The controller is provided with a wireless receiver, so that the output power can be conveniently and remotely adjusted. For example, in the fire extinguishing process, a firefighter can carry a remote controller at hand, the output power is adjusted according to the height of a fire to be extinguished, and the firefighter does not need to reach the side of a fire pump, so that stable propulsion of fire extinguishing work is facilitated.

In this embodiment, referring to fig. 10, the angles between the bypass shunt tubes 133 and the connection positions of the main water inlet pipe 131 and the main water outlet pipe 132 are all smaller than 30 °.

The curved conduit may detract from the fluid pressure within the conduit, and the smaller the angle of the curve the more pronounced the pressure detract from. One reason is that when fluid flows through the bend of the pipeline, the travel of the fluid on the inner side and the outer side of the bend is different, speed difference is formed among water molecules, even dead water areas or vortex areas are formed when the fluid flows through the local part of the bend, the liquid does not participate in main flow in the areas, the liquid is continuously swirled, friction among the liquid is accelerated, particle collision is caused, and local energy loss is generated.

For medium-low pressure fluid, the angle of the bent pipe is generally required to be not smaller than 90 degrees, and in consideration of the application scenario of the fire pump of the embodiment, the pressure of the fluid in the pipe may be larger, when the bypass mode is performed, the angle of the connecting angle of the pipe smaller than 30 degrees is equivalent to the angle of the water flow direction larger than 150 degrees, the change of the water flow direction is smaller, the pressure in the water pipe is more beneficial to be kept, and the pressure loss generated by the bypass shunt pipe of the self-adaptive booster pump of the embodiment is reduced.

Further, the axis of the bypass shunt 133 may be an arc of continuous curvature. Similar to the above-described principle, the bending of the pipe itself also causes pressure loss to the fluid inside the pipe, and the smaller the bending angle and bending radius of the pipe, the larger the loss to pressure. Curvature continuity refers to a continuous point of curve, i.e., the axis of the bypass shunt is a smooth curve, thereby reducing the pressure loss of fluid in the bypass shunt to an acceptable level.

In addition, the arc-shaped pipeline can enable the two ends of the bypass shunt pipe to be connected with the main water inlet pipe and the main water outlet pipe in a tangential mode.

In this embodiment, the ratio of the cross-sectional areas of the inner pipes of the main water inlet pipe 131 and the main water outlet pipe 132 is 1.2-1.8, the inner diameter of the bypass shunt pipe 133 along the water flow direction is gradually reduced, and at least one guide vane 1331 is further disposed at the inlet of the bypass shunt pipe 133.

The main inlet and the main outlet of the booster pump have unchanged flow, but have different pressures, under the conditions of high-speed flow and pressure change, the phenomenon of cavitation corrosion damage occurs on the metal surface contacted with the fluid, and the phenomenon often occurs in a high-speed decompression area of the pump, so that cavitation is formed, the cavitation is crushed in the high-pressure area and generates impact pressure, a protective film on the metal surface is damaged, the corrosion speed is increased, and then the cavitation is gradually enlarged.

The flow rates of the fluid flowing through the inlet and the outlet of the pump are the same, if the design is that the pipe diameter of the water suction pipe is large and the pipe diameter of the water outlet pipe is small, the flow rate of the water suction pipe is correspondingly smaller than that of the water outlet pipe, so that the hydraulic loss of the water suction pipe can be reduced, and cavitation of the pump body can be prevented. On the other hand, the design of the pipe diameter of the water outlet pipe is smaller, so that the diameter of the rear-end pipeline is reduced, and the material cost for paving the rear-end pipeline is reduced.

One end of the bypass shunt tube is connected with the main water inlet tube, the other end of the bypass shunt tube is connected with the main water outlet tube, and the inner diameter of the bypass shunt tube is gradually reduced, so that the gradual transition from the section of the main water inlet tube to the section of the main water outlet tube is realized, and the influence on the pressure of fluid due to abrupt change of the tube diameter is avoided.

Guide vanes are also commonly used in air outlets of automotive air conditioners, and are generally used for changing the direction of fluid, and simultaneously reducing resistance caused by reversing to the fluid to the greatest extent. In particular, in this embodiment, the fluid pressure in the duct is much greater than in the context of an air conditioner. The guide vane is arranged at the inlet of the bypass shunt tube, has the functions of assisting reversing and reducing flow path switching loss, and also has the function of protecting a pipeline to a certain extent. The single guide vane is of a sheet structure, and the guide vane is arranged at the position of fluid reversing and has a guiding effect on the direction of fluid. When high-pressure water flows in, only one side of the pipeline can be subjected to larger impact originally, after the guide vanes are arranged, the original pipeline is cut into a plurality of water flow channels, the impact force of the water is dispersed by the guide vanes and is conducted to the periphery of the pipe diameter along the guide vanes, and the impact of the high-pressure water flow on one side of the pipeline is reduced. In specific implementation, the guide vane can be arranged in a grid shape or in a sheet structure with intervals.
