[0002] Construction dust prevention equipment is specially designed to reduce dust generated during construction and protect the environment and workers' health. The method of eliminating dust is to collect dust in the form of spray or water curtain combined with on-site dust.

[0003] However, the prior art still has shortcomings. For example, a green construction dust prevention device for construction with patent number: CN202223227153.9 relates to the field of construction dust prevention technology, and includes a shell, and openings are respectively opened on both sides of the shell, and water curtains A are respectively fixedly connected to the two openings, and a fixed plate B is fixedly connected inside the shell. After long-term use, scale will appear in the pipeline of the device.

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Example 1: Reference Figure 1-Figure 14 A construction dust prevention device for green building construction includes: a shell 1, a water outlet pipe 2, a water pump 3, a pressure mechanism 4 and an adjusting mechanism 5. The shell 1 is equipped with a water outlet pipe 2 and a water pump 3. The end of the water pump 3 is placed outside the shell 1, and the other end of the water pump 3 is connected to the end of the water outlet pipe 2. The other end of the water outlet pipe 2 is placed outside the shell 1 and connected to the nozzle. The water outlet pipe 2 is connected with a pressure mechanism 4 and an adjusting mechanism 5, and the pressure mechanism 4 is connected to the adjusting mechanism 5.

[0035] The principle of the above scheme is:

[0036] The end of the water pump 3 is connected to the water supply mechanism. When the device needs to be dustproof, the water pump 3 is started, and the water in the water supply mechanism enters the water outlet pipe 2 through the water pump 3, and then enters the nozzle through the water outlet pipe 2 and is sprayed out. The sprayed water forms a water curtain or water mist to combine with the dust in the construction site to implement the dust prevention function of the device. After a period of use, scale will be produced in the water outlet pipe 2. The accumulation of scale causes the volume of water sprayed from the nozzle to decrease, which seriously reduces the dust prevention effect of the device. At this time, due to the accumulation of scale in the water outlet pipe 2, the pressure mechanism 4 is adjusted based on the current water pressure in the water outlet pipe 2, so as to obtain the volume of cleaning water used for cleaning the water outlet pipe 2. After the device finishes the dust prevention work, the regulating mechanism 5 is started and uses the water in the pressure mechanism 4 to start impacting the scale in the water outlet pipe 2 to implement the cleaning work of the scale.

[0037] The beneficial effects of the above scheme are:

[0038] The pressure mechanism 4 arranged in the device can obtain the volume of cleaning water used for cleaning the water outlet pipe 2. Therefore, when the regulating mechanism 5 cleans the scale in the water outlet pipe 2, it can avoid the water outlet pipe 2 from rupturing due to excessive cleaning water volume, or the scale from being unable to be cleaned due to too small cleaning water volume.

[0039] Example 2: Reference Figure 1-Figure 14 The pressure mechanism 4 includes: a pressure column 6, an inclined surface 7, a pipe 8, a mounting ring 9 and a spring 10. The bottom of the water outlet pipe 2 is connected to the top of the pipe 8, and the pressure column 6 is slidably connected in the pipe 8. The end of the pressure column 6 placed in the water outlet pipe 2 is provided with an inclined surface 7, and the inclined surface 7 is arranged toward the water pump 3. The bottom of the pressure column 6 placed below the pipe 8 is connected to the mounting ring 9, and the top of the mounting ring 9 is connected to the bottom of the pipe 8 through the spring 10.

[0040] The principle of the above scheme is:

[0041] When the device starts to remove dust, there is a high water flow rate in the water outlet pipe 2, and the impact force of the water on the inclined surface 7 at the top of the pressure column 6 increases, thereby causing the pressure column 6 to move downward along the pipe 8, and the length of the spring 10 connected to the mounting ring 9 is extended;

[0042] When the device finishes dust removal, the water flow velocity in the water outlet pipe 2 decreases until the water flow stops, the impact force of the water on the inclined surface 7 gradually decreases until it disappears, and under the elastic force of the spring 10 returning to its original position, the pressure column 6 moves upward along the pipe 8.

[0043] The beneficial effects of the above scheme are:

[0044] Since the top of the pressure column 6 is placed in the water outlet pipe 2, this part of the pressure column 6 can preliminarily destroy the scale or impurities in the water flow, thereby slowing down the speed of scale accumulation in the water outlet pipe 2; since the inclined surface 7 is arranged toward the water pump 3, when there is a change in the flow rate of the water flow in the water outlet pipe 2, the pressure exerted on the inclined surface 7 can be transmitted to the pressure column 6. When the pressure column 6 is reset by the elastic force of the spring 10, the pressure column 6 vibrates the water outlet pipe 2, so the scale just formed in the water outlet pipe 2 will fall off from the inner wall of the water outlet pipe 2, further realizing the daily cleaning and destruction of the scale in the water outlet pipe 2 and reducing its sedimentation rate.

[0045] Example 3: Reference Figure 1-Figure 14 The pressure mechanism 4 also includes: a lifting column 11, a piston 12, a water tank 13 and a water inlet pipe 14. The bottom of the pressure column 6 is connected to the top of the lifting column 11 placed above the water tank 13. The water tank 13 is connected to the inner wall of the shell 1. The lifting column 11 is slidably connected to the water tank 13. The end of the lifting column 11 placed in the water tank 13 is connected to the piston 12. The piston 12 and the water tank 13 are slidably sealed. A water storage cavity is formed between the bottom of the piston 12 and the inner wall of the water tank 13. The inner wall of the water storage cavity is connected to the end of the water inlet pipe 14. The other end of the water inlet pipe 14 is placed outside the shell 1.

[0046] The water inlet pipe 14 is connected to the end of the water return pipe 15 , and the other end of the water return pipe 15 is connected to the inner wall of the water storage chamber. A one-way valve is connected in the water inlet pipe 14 , and a second one-way valve is connected in the water return pipe 15 .

[0047] The principle of the above scheme is:

[0048] After the device has been used for many times, a large amount of scale appears in the water outlet pipe 2. Therefore, compared with the normal working condition, that is, when there is no scale in the water outlet pipe 2, the internal diameter of the pipe structure is significantly reduced. When the water outlet pipe 2 supplies water to the nozzle, the water flow rate in it will be significantly increased. The increase in the water flow rate in the water outlet pipe 2 causes the inclined surface 7 at the top of the pressure column 6 to be impacted by more water. During operation, compared with the case when there is no scale in the water outlet pipe 2, the downward movement distance of the pressure column 6 is greatly increased. The pressure column 6 drives the lifting column 11 and the piston 12 to move downward, and the volume of the water storage chamber formed by the bottom of the piston 12 and the inner wall of the water storage tank 13 is reduced. The one-way valve 2 is opened, and the excess water in the water storage chamber passes through the return pipe 15. The one-way valve 2 connected inside enters the water inlet pipe 14, and then the one-way valve 2 is closed. The remaining water in the water storage chamber is greater than the water used for cleaning the water outlet pipe 2; when the device starts to clean the scale, the pressure column 6 first drives the lifting column 11 and the piston 12 to move downward, and a one-way valve 2 is provided in the return pipe 15. The water discharge amount of the one-way valve 2 is pre-set. Therefore, when the water in the water storage chamber is discharged, part of the water enters the water inlet pipe 14 through the one-way valve 2 in the return pipe 15, and the remaining water in the water storage chamber flows out and cleans the water outlet pipe 2. Then the pressure column 6 drives the lifting column 11 and the piston 12 to move upward. At this time, the water in the water in the water inlet pipe 14 enters the water storage chamber through the one-way valve.

[0049] The beneficial effects of the above scheme are:

[0050] The generation of scale in the water outlet pipe 2 will cause the height of the pressure column 6 to decrease when it is working. The user can judge whether to clean the scale based on the actual water spraying situation and the length of the bottom of the pressure column 6 extending to the bottom of the pipe 8. Therefore, the thickness of the scale in the device can be intuitively judged by the height of the pressure column 6; the volume of water in the water storage chamber is larger than the volume of water used for cleaning the water outlet pipe 2. Such a setting can prevent the water in the water storage chamber from adhering to the inner wall of the water storage chamber due to surface tension when supplying water to the regulating mechanism 5, thereby causing the volume of the cleaning water to decrease, further improving the accuracy of the control of the cleaning water usage, and by setting the inclined surface 7 on the pressure column 6 to directly contact the water flow in the water outlet pipe 2, the increase in the flow rate of the water flow is converted into a decrease in the height of the pressure column 6, and through The pressure column 6 drives the lifting column 11 and the piston 12 to compress the water storage chamber, and the one-way valve 2 allows the excess water in the water storage chamber to enter the water inlet pipe 14 through the return pipe 15. The device can extremely accurately and autonomously adjust the required cleaning water usage to avoid the device from using too much water when flushing the water outlet pipe 2; after the scale cleaning of the water outlet pipe 2 is completed, before the device works again, the water inlet pipe 14 replenishes the water storage chamber of the water storage tank 13 with water when the pressure column 6 rises, and the return pipe 15 discharges the excess water in the water storage chamber to the water inlet pipe 14 when the pressure column 6 descends, which can ensure that the remaining water in the water storage chamber is the cleaning water of the water outlet pipe 2, thereby improving the accuracy of water storage; the setting of the one-way valve and the one-way valve 2 can control the flow direction of the water inlet pipe 14 and the return pipe 15.

[0051] Example 4: Reference Figure 1-Figure 14 The pressure mechanism 4 also includes: a second water outlet pipe 16, the inner wall of the water storage chamber is connected to the end of the second water outlet pipe 16, the second water outlet pipe 16 is connected to a solenoid valve, the other end of the second water outlet pipe 16 is connected to the regulating mechanism 5, and the inner diameter of the second water outlet pipe 16 is larger than the inner diameter of the return pipe 15.

[0052] The principles and beneficial effects of the above scheme are:

[0053] When the device starts to clean the water outlet pipe 2, the solenoid valve opens, and the water in the water storage chamber enters the regulating mechanism 5 through the water outlet pipe 16, and some excess water flows into the water inlet pipe 14 through the return pipe 15. Since the inner diameter of the water outlet pipe 16 is larger than the inner diameter of the return pipe 15, it can avoid excessive return water from the water storage chamber and speed up the supply speed from the water storage chamber to the regulating mechanism 5. Then the regulating mechanism 5 cleans the water outlet pipe 2, which greatly simplifies the complexity of the structure inside the device. At the same time, the one-way valve and the one-way valve 2 can prevent excess water from entering the regulating mechanism 5, further improving the accuracy of the supply of cleaning water usage.

[0054] Example 5: Reference Figure 1-Figure 14The bottom of the pressure column 6 is connected with a rack 17, and the teeth of the rack 17 are slidably matched with the second inclined plane. The second inclined plane is arranged at the top of one end of the plug rod 18, and the second inclined plane is arranged toward the top of the rack 17. The bottom of one end of the plug rod 18 is in contact with another tooth of the rack 17. The plug rod 18 is slidably connected with the regulating tank 21, and the regulating tank 21 is slidably sealed with the second piston 19. The second piston 19 is connected with the other end of the plug rod 18 placed in the regulating tank 21. The side wall of the second piston 19 is connected to the inner wall of the regulating tank 21 through the second spring 20. The side wall of the second piston 19 and the inner wall of the regulating tank 21 form an adjusting chamber, and the adjusting chamber is filled with hydraulic oil. The inner wall of the adjusting chamber is connected with the top of the second pipe 22, and a two-way throttle valve is installed in the second pipe 22. The bottom of the second pipe 22 is placed inside the outlet pipe 16, and the bottom of the second pipe 22 is connected with a pressure component to seal the second pipe 22.

[0055] The pressure assembly includes: a second mounting ring 23, the inner wall of the bottom of the second pipe 22 is connected with the second mounting ring 23, the bottom of the second mounting ring 23 is connected to the top of the second pressure column 25 through a third spring 24, the second pressure column 25 is slidably sealed with the inner wall of the second pipe 22, and the bottom of the second pressure column 25 is placed below the second pipe 22.

[0056] The principle of the above scheme is:

[0057] When the pressure column 6 moves downward, the bottom surface of the teeth on the rack 17 slides with the inclined surface 2 on the top of one end of the plug rod 18 to make it move toward the direction of the regulating tank 21, and the piston 2 19 moves synchronously. The spring 20 is stretched and reset to reset the piston 2 19 and the plug rod 18. Since the bottom of one end of the plug rod 18 can contact the top surface of the teeth of the rack 17, when the downward movement of the rack 17 stops, the plug rod 18 locks the rack 17 to prevent the piston 12 from moving. When the solenoid valve is opened, water flows in the outlet pipe 2 16. At this time, the flowing water impacts the bottom of the pressure column 25, and the pressure column 25 moves upward in the pipe 22. The spring 3 24 is compressed, the volume of the hydraulic oil in the regulating chamber increases, the plug rod 18 and the piston 2 19 move toward the regulating tank 21, the spring 20 is compressed, the plug rod 18 stops locking the rack 17, and the rack 17 moves upward and resets; when the water flow in the outlet pipe 2 16 stops, the pressure column 25 moves downward and the spring 3 24 resets, the volume of the hydraulic oil in the regulating chamber decreases, and finally the plug rod 18 is re-inserted and matched with the rack 17; since a two-way throttle valve is provided in the pipeline 22, its specific model is: FTD-2C, and the flow rate of the hydraulic oil entering the regulating chamber through the two-way throttle valve is set to be greater than the flow rate of the hydraulic oil flowing out of the regulating chamber through the two-way throttle valve.

[0058] The beneficial effects of the above scheme are:

[0059] The second inclined surface is slidably matched with the bottom surface of the teeth on the rack 17, which can ensure that the plug rod 18 moves in the direction of the regulating tank 21. Under the action of the elastic force of the second spring 20, the plug rod 18 is slidably matched with the bottom surface of another tooth above the rack 17, further realizing the plug-in match of the plug rod 18 to the rack 17, and positioning the piston 12, thereby improving the stability of the mechanism when locked. When the plug rod 18 and the rack 17 need to be unlocked, only the flow of water in the second water outlet pipe 16 is required, thereby reducing the complexity of the device when unlocking; the mechanism utilizes the characteristic that the hydraulic oil is not easily compressed, and through the pressure column The rise of spring 25 compresses the hydraulic oil in pipe 22 into the regulating chamber, and applies pressure to piston 19 to control rod 18 to maintain the unlocked state with rack 17, thereby improving the stability of the mechanism when unlocked; since the flow rate of hydraulic oil entering the regulating chamber through the two-way throttle valve is greater than the flow rate of hydraulic oil flowing out of the regulating chamber through the two-way throttle valve, when the water flow in water outlet pipe 16 stops, the speed of spring 20 returning to its original position slows down, so that spring 10 has enough time to return to its original position, further ensuring that rack 17 will not be locked before piston 12 returns to its original position and the water storage chamber is filled with water.

[0060] Example 6: Reference Figure 1-Figure 14 The regulating mechanism 5 includes: a ball valve 26, a second ball valve 27, a flushing pipe 29, a second flushing pipe 30 and a connecting pipe 31. The water outlet pipe 2 is connected with the ball valve 26 and the second ball valve 27. The exhaust valve on the water outlet pipe 2 is arranged between the ball valve 26 and the second ball valve 27. The ball valve 26 is arranged adjacent to the water pump 3. The ends of the flushing pipe 29 and the second flushing pipe 30 are respectively connected to the two sides of the water outlet pipe 2. The flushing pipe 29 and the second flushing pipe 30 are arranged between the ball valve 26 and the second ball valve 27. The other ends of the flushing pipe 29 and the second flushing pipe 30 are respectively connected to the two sides of the connecting pipe 31. The connecting pipe 31 is connected to the other end of the second water outlet pipe 16. A power component is connected to the connecting pipe 31.

[0061] The principle of the above scheme is:

[0062] When the device starts to clean the water outlet pipe 2, the ball valve 26 and the second ball valve 27 are adjusted to be closed, and water enters the connecting pipe 31 through the second water outlet pipe 16, and then enters the water outlet pipe 2 through the flushing pipe 29, and then enters the flushing pipe 2 30 through the water outlet pipe 2. The setting of the exhaust valve on the water outlet pipe 2 can ensure that the water outlet pipe 2 is completely filled with cleaning water, and ensure that there is no gas in the water outlet pipe 2 when the device is working. Then, the cleaning water is circulated by starting the power component to implement the flushing of the water outlet pipe 2. The exhaust valve is specifically a valve body with two working conditions of open or closed, and its specific model is: VIRAX-05100.

[0063] The beneficial effects of the above scheme are:

[0064] The setting of the exhaust valve can ensure that the water outlet pipe 2 is filled with water, thereby ensuring that there will be no vibration and noise in the water outlet pipe 2 when cleaning is being carried out. At the same time, it can avoid the bursting and movement of bubbles, which may cause local stress concentration on the inner wall of the water outlet pipe 2, which may cause cracks or other structural damage to the wall of the water outlet pipe 2 under long-term action, and further avoid the increase in the flow resistance of the cleaning water. Specifically, it can avoid the presence of bubbles that will change the flow characteristics of the cleaning water, which may cause an increase in the flow resistance, thereby avoiding affecting the power transmission efficiency and energy consumption of the system when the power component drives the fluid to flow.

[0065] Example 7: Reference Figure 1-Figure 14 The power assembly includes: a motor 28, the bottom of the rotating shaft 32 of the ball valve 26 is connected to the output end of the motor 28, the motor 28 is installed on the inner wall of the shell 1, the rotating shaft 32 is rotatably connected to the end of the rocker 33, the other end of the rocker 33 is hinged to the end of the connecting rod 34, the other end of the connecting rod 34 is hinged to the end of the rocker 2 35, and the other end of the rocker 2 35 is connected to the bottom of the rotating shaft 2 36 of the ball valve 27.

[0066] The principles and beneficial effects of the above scheme are:

[0067] The ball valve 26 and the second ball valve 27 have the same structure, and the specific model is: Q41F-16C. The opening and closing of the valve body can be implemented by the rotating shaft mechanism on the valve body, that is, the rotating shaft 32 and the second rotating shaft 36 in this mechanism;

[0068] When it is necessary to clean the water outlet pipe 2, start the motor 28, and the output end of the motor 28 drives the shaft 32 to rotate to the left, and the swing rod 33 rotates synchronously. Under the action of the connecting rod 34, the swing rod 35 rotates to the left synchronously, and then the shaft 36 rotates to the left synchronously, and the ball valve 26 and the ball valve 27 are closed; when the cleaning of the water outlet pipe 2 is finished, start the motor 28 again, and the output end of the motor 28 drives the shaft 32 to rotate to the right, and the swing rod 33 rotates synchronously. Under the action of the connecting rod 34, the swing rod 35 rotates to the right synchronously, and then the shaft 36 rotates to the right synchronously, and the ball valve 26 and the ball valve 27 are opened, which improves the synchronization when the valve body is opened and closed, increases the stability of the mechanism during operation, and simplifies the logic control while improving the response speed of the mechanism.

[0069] Example 8: Reference Figure 1-Figure 14 A gear 37 is connected to the rotating shaft 32, and the gear 37 is meshed with a rack 2 38. The end of the rack 2 38 is connected to one side of a mounting plate 39, and the other side of the mounting plate 39 is connected to the end of a spring 40 and a drive tube 41. The other end of the spring 40 is connected to the open end of the connecting tube 31, and the drive tube 41 is slidably sealed with the connecting tube 31. The other end of the drive tube 41 is connected to a sealing disk.

[0070] The principles and beneficial effects of the above scheme are:

[0071] When the shaft 32 rotates to the left, the gear 37 also rotates to the left synchronously, thereby driving the rack 2 38 to move to the left, and the mounting plate 39 drives the drive tube 41 to move to the left and compresses the spring 4 40. When the shaft 32 rotates to the right, the gear 37 also rotates to the right synchronously, thereby driving the rack 2 38 to move to the right, and the mounting plate 39 drives the drive tube 41 to move to the right and resets the spring 40. The mechanism fully utilizes the power output by the motor 28, and drives the gear 37 to rotate through the rotation of the shaft 32, and drives the rack 2 38 meshing therewith to move, thereby improving the utilization efficiency of the power within the mechanism. The integrated arrangement of components facilitates rapid maintenance and troubleshooting when a failure occurs in the device.

[0072] Example 9: Reference Figure 1-Figure 14 A pressure relief valve 42 is connected to the top of the connecting pipe 31, a pressure relief hole 43 is opened on the driving pipe 41, and the pressure relief hole 43 is arranged toward the pressure relief valve 42. A circular hole 44 is opened on the driving pipe 41, and the circular hole 44 is arranged concentrically with the other end of the flushing pipe 29. A one-way valve 3 is connected to the air inlet pipe of the flushing pipe 29, and the output end of the high-pressure pump is connected to the flushing pipe 29. The high-pressure pump is connected to the inner wall of the shell 1, and the high-pressure pump is arranged between the one-way valve 3 and the water outlet pipe 2. A discharge pipe 58 is connected to the bottom of the flushing pipe 20, and an electromagnetic valve 2 is arranged in the discharge pipe 58. The material of the flushing pipe 20 is specifically rubber.

[0073] The principles and beneficial effects of the above scheme are:

[0074] When the device is working normally, the flushing pipe 2 30 can assist in collecting the water flowing in the water outlet pipe 2. When the water pressure in the water outlet pipe 2 is too high, excess water enters the flushing pipe 2 30 to prevent abnormally high pressure in the water outlet pipe 2, which would cause damage to its structure. At the same time, as the water flows from the initial end in the pipeline structure to the output end, it is affected by the friction of the inner wall of the pipeline structure and the fluid resistance. The pressure at the initial end of the pipeline structure is higher than the pressure at its output end. Since the other end of the flushing pipe 2 30 is arranged close to the water pump 3, when the water outlet pipe 2 is working and the water pressure therein increases instantaneously, excess water enters the flushing pipe 2 30, enters the pressure relief hole 43 through the circular hole 44, and finally discharges the excess water through the pressure relief valve 42 on the connecting pipe 31, further increasing the safety of the device during use and preventing the flushing pipe 2 30 from being damaged due to excessive pressure.

[0075] Example 10: Reference Figure 1-Figure 14 A guide hole 45 is provided between the circular hole 44 and the second water outlet pipe 16 . The guide hole 45 is opened on the side wall of the driving pipe 41 . The guide hole 45 and the circular hole 44 are opened on the same side wall of the driving pipe 41 .

[0076] A second circular hole 46 is formed on the other side wall of the driving tube 41 . The second circular hole 46 is disposed between the open end of the connecting tube 31 and the flushing tube 29 .

[0077] The principles and beneficial effects of the above scheme are:

[0078] The high-pressure pump is specifically a screw pump widely used in the prior art that can supply the liquid phase and the gas phase separately. After the drive tube 41 moves to the left, the circular hole 44 ends the conduction with the flushing pipe 30, and the guide hole 45 is connected with the outlet pipe 16. The cleaning water enters the drive tube 41 through the guide hole 45, enters the flushing pipe 29 through the circular hole 46, and then enters the flushing pipe 230 through the outlet pipe 2 to complete the injection of the flushing water. The high-pressure pump is started to work, and the high-pressure pump causes the water in the pipeline structure to flow from the flushing pipe 29 to the flushing pipe 30. At the same time, the solenoid valve 2 is opened and The exhaust valve is closed, and the scale on the inner wall of the outlet pipe 2 is impacted and broken by the flow of the cleaning water and discharged through the discharge pipe 58. Since the high-pressure pump in the flushing pipe 29 is started, the one-way valve 3 is opened at the same time to ensure that the cleaning water can flow continuously. At the same time, the air entering the flushing pipe 29 through the air inlet pipe can flush the loose scale particles on the inner wall of the pipe through the air flow. This flushing effect is similar to the flushing of cleaning water, but the flow rate and pressure of the air flow are usually higher, so it can more effectively remove the scale that is not firmly attached to improve the cleaning effect of the outlet pipe 2;

[0079] Due to the presence of residual scale, pressure fluctuations will occur when the air flows, and a huge pressure difference will be formed at both ends of the scale. The pressure fluctuations can loosen the scale attached to the inner wall of the pipe, making it easier to be washed away by the airflow;

[0080] During the air flow, the scale with the smallest remaining volume begins to dry, and the stripping effect of the airflow can further remove the last part of the scale, thus improving the thoroughness of the device in cleaning scale.

[0081] The setting of the high-pressure pump is not only convenient for conveying water, but also greatly improves the practicability of the mechanism because it can convey air, and air is highly suitable for cleaning short-distance pipeline structures.

[0082] Example 11: Reference Figure 1-Figure 14The bottom of the water outlet pipe 2 is connected to the top of the standpipe 47, and a piston three 48 is slidably connected in the standpipe 47. The top of the piston three 48 and the inner wall of the standpipe 47 form an air storage chamber, and the air storage chamber is filled with nitrogen. The top of the piston three 48 is connected to the top wall of the standpipe 47 through a spring five 49, and the bottom of the piston three 48 is connected to the top of the rod body 50. The rod body 50 is placed at the bottom below the bottom opening of the standpipe 47 and is rotatably connected to the spline shaft 51. The top of the spline shaft 51 is slidably connected to the spline jack at the bottom of the pump shaft extending from the body of the water pump 3, and the bottom of the spline shaft 51 is connected to a conical rubber The conical rubber column 52 has its conical surface facing the drive shaft 53 and is arranged at the top above the pump housing 54. The conical rubber column 52 is located above the drive shaft 53. The pump housing 54 is connected to the inner wall of the housing 1. The drive shaft 53 is rotatably connected to the pump housing 54. The bottom end of the drive shaft 53 placed in the pump housing 54 is connected with a plurality of fan blades 55. One side of the pump housing 54 is connected to the end of an air inlet pipe 56. The other end of the air inlet pipe 56 is arranged outside the housing 1. The other side of the pump housing 54 is connected to the end of an exhaust pipe 57. The other end of the exhaust pipe 57 is arranged toward the output end of the water pump 3.

[0083] The principles and beneficial effects of the above scheme are:

[0084] Since the water pump 3 generates heat when working, and since the water flow rate at the output end of the water pump 3 is fast, the temperature of this part rises quickly, the volume of nitrogen in the air storage chamber in the vertical pipe 47 expands, the piston three 48 drives the rod body 50 to move downward, the spring five 49 is stretched, and the downward movement of the rod body 50 drives the spline shaft 51 rotatably connected thereto to move downward. The water pump 3 is specifically a liquid supply pump with a long axis. According to the prior art, when supplying liquid, it is necessary to drive the pump shaft to rotate through the pump motor in the pump body, and the pump shaft drives the blades to rotate to implement the supply of liquid. The bottom end of the pump shaft of the water pump 3 in this scheme is placed below its body, and is slidably connected to the spline shaft 51 through the spline socket opened at the bottom of the pump shaft. Therefore, the spline shaft 51 can also rotate while moving downward. When the spline shaft 51 drives the conical surface of the conical rubber column 52 to rub against the top of the drive shaft 53 After the friction fit, the drive shaft 53 drives the fan blades 55 to rotate synchronously, and then the external air is input into the pump housing 54 through the air inlet pipe 56, and then input into the exhaust pipe 57 through the pump housing 54, and the air is output to the output end of the water pump 3 through the other end of the exhaust pipe 57, and the temperature of this part is reduced to prevent the rapid formation of scale caused by excessive water temperature, that is, to prevent the calcium and magnesium ions dissolved in the water from reaching a saturated state, thereby precipitating to form scale; at the same time, the precipitation reaction rate of calcium carbonate in the water can be reduced; when the device finishes working, the temperature in the water outlet pipe 2 decreases, the volume of nitrogen in the air storage chamber decreases, and the reset of the spring five 49 drives the piston three 48, the rod body 50 and the spline shaft 51 to reset, so as to prepare for the next work; since the specific material of the conical rubber column 52 is rubber, when the conical rubber column 52 rubs against the top of the drive shaft 53, it can better transmit the rotational power to the drive shaft 53.
