[0004] In the prior art including the above-mentioned patent, when constructing steel formwork load-bearing columns in areas with large temperature differences between day and night, the obvious changes in humidity and temperature will affect the hydration reaction rate of the concrete, and at the same time increase the temperature stress inside the concrete, increasing the risk of cracks in the concrete. The maintenance methods used in the normal construction process cannot overcome the interference of temperature on the concrete, which will have an adverse effect on the safety of the load-bearing columns and extend the construction period. Summary of the invention

[0007] A method for moisturizing a steel mold load-bearing column after pouring, comprising a cement column provided with a steel mold casing, and a spray rack divided into a sunshade cylinder, a water storage cylinder and a drainage cylinder according to functions, wherein the following steps are also included:

[0008] S1. Insert the water delivery hose into the pipe opening at the axis of the water storage cylinder, and then install the bracket on the spray rack on the port of the steel mold casing;

[0009] S2, the upper frame hinged on the side wall of the drainage tube and arranged in a circumferential manner abuts against the port of the steel mold casing, and the upper membrane installed on the upper frame closes the port of the steel mold casing;

[0010] S3, the lower frame hinged on the side wall of the drainage cylinder and arranged in a circumference is attached to the upper end of the cement column, and the lower membrane installed on the lower frame covers the upper surface of the cement column;

[0011] S4. Under high temperature conditions during the day, a large amount of water is added to the hydraulic chamber in the drainage cylinder through a hose, and the water pressure is used to open the lower drain port at the bottom of the drainage cylinder, so that the water is sprayed on the cement column to keep it moisturized;

[0012] S5. The pressure generated when the hydraulic chamber is filled with water drives the plug ring inside to slide upward, and triggers the electric push rod on the spraying frame to push the upper frame to deflect, so that the upper membrane opens the steel mold casing to deflate, and simultaneously moves the lower membrane away from the upper end surface of the cement column to increase the spraying area;

[0013] S6. Under low temperature conditions at night, reduce the water flow rate in the hose, so that when the water in the hydraulic chamber reaches the critical value, the lower drain port will open automatically to drain water and remain stable;

[0014] S7. The lower film is kept warm during the process of being attached to the upper surface of the cement column, and the compartment formed between the upper film and the lower film stores heat.

[0015] Preferably, a storage shell is provided at the bottom of the steel mold casing, and a sunshade cloth covering the entire outer side of the steel mold casing is provided in the storage shell;

[0016] A clamping head is arranged at the end of the upper frame, and a sliding sleeve which is clamped and assembled with the clamping head is fixedly installed at the upper end of the sunshade cloth.

[0017] Preferably, in the deflected state, the upper frame makes the sliding sleeve slide on the clamping head and makes the upper end of the sunshade cloth away from the outer side wall of the steel mold casing.

[0018] Preferably, a needle tube is provided at the end of the water storage cylinder, and the plug ring moves to a high position so that the plug head on it is pushed open by the needle tube, so that the needle tube is connected to the hydraulic chamber;

[0019] The sunshade tube conveys water in the water storage tube and sprays it out at the plurality of external nozzles.

[0020] Preferably, the drainage cylinder is further provided with a transfer chamber opened and closed by a plug, and the upper end of the upper frame is provided with an upper transfer head connected to the transfer chamber;

[0021] The upper frame is provided with a water channel connected to the upper rotating head, and an atomizing frame for atomizing and spraying water into the compartment is arranged in the water channel.

[0022] Preferably, the end of the water channel is provided with an inner nozzle connected to the inner side of the sunshade cloth.

[0023] Preferably, the upper membrane in the active state cooperates with the water storage cylinder to enable the needle tube to discharge water toward the plug.

[0024] Preferably, the end of the guide rod is provided with a trigger head that pushes and cooperates with the atomization frame, and the water channel refluxes the discharged water of the needle tube.

[0025] Preferably, the backflow water of the water channel is discharged from the inner nozzle and gathered in the storage shell.

[0026] Preferably, the outer nozzle drips water onto the upper membrane surface and gathers at the position of the upper rotor.

[0027] In the above technical scheme, a method for moisturizing a steel mold load-bearing column after pouring provided by the present invention has the following beneficial effects: a large amount of water is poured into the water supply hose during the day, so that the pressure of the water sprayed downward from the pipe mouth can flush the valve plate of the lower outlet, so that the upper end of the cement column is filled and covered with water until the water penetrates into the interior of the cement column and flows downward along the side wall of the cement column to complete the moisturizing work, and in the process of the plug ring moving up, the trigger sheet on the guide rod presses the touch switch, so that the convex block at the output end of the electric push rod slides to push the upper frame to deflect, and the upper film is moved away from the steel mold casing port with the upper frame, so as to realize the ventilation function in the process of watering and moisturizing the cement column, and at the same time, the heat insulation layer and the reflective layer are used to cool the compartment to reduce the problem of excessive surface temperature of the cement column causing a large amount of water evaporation, and in the process of the upper frame deflection, the lower frame is pulled by the pull rope to move synchronously, so that the moisturizing cloth of the lower film is kept away from the upper surface of the cement column, so as to ensure that the water sprayed during the day can be used in large quantities. It is used to moisturize the cement column, and the water volume of the water hose is reduced at night. After the water storage in the hydraulic chamber reaches a critical value, the water pressure opens the valve plate in the lower outlet to moisturize the cement column. At the same time, because the hydraulic chamber maintains a stable state of water inlet and outlet, the upward plug ring cannot trigger the electric push rod, so the lower frame remains in the default state, so that the edge of the lower membrane fits and covers the upper surface of the cement column, and the terraced area formed between the lower membrane and the cement column can store the water discharged from the lower outlet in this area and maintain moisturizing for a long time, reducing the water consumption at night while ensuring the moisturizing effect, and the fitted lower membrane provides a heat preservation function, and the partition cavity forms a heat preservation chamber under the shielding effect of the upper membrane, so that the cement column has a better heat preservation effect at night, reducing the influence of a large range of temperature changes on the hydration reaction rate of the cement column, while also reducing the temperature stress in the cement column, and improving the moisturizing molding effect of the cement column.

DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] like Figure 1-9 As shown, a method for moisturizing a steel mold load-bearing column after pouring includes a cement column 1 provided with a steel mold casing 11, and also includes a spray rack 2 divided into a sunshade cylinder 21, a water storage cylinder 22 and a drainage cylinder 23 according to functions, wherein the following steps are also included:

[0042] S1, insert and install the water delivery hose into the pipe opening 221 at the axis of the water storage cylinder 22, and then install the hanger 20 on the spray rack 2 on the port of the steel mold casing 11;

[0043] S2, the upper frame 26 hinged and circumferentially arranged on the side wall of the drainage tube 23 contacts the port of the steel mold casing 11, and the upper membrane 260 installed on the upper frame 26 closes the port of the steel mold casing 11;

[0044] S3, the lower frame 27 hinged and arranged in a circumferential manner on the side wall of the drainage cylinder 23 is attached to the upper end of the cement column 1, and the lower membrane 270 installed on the lower frame 27 covers the upper surface of the cement column 1;

[0045] S4. Under high temperature conditions during the day, a large amount of water is added to the hydraulic chamber 231 in the drain cylinder 23 through a hose, and the water pressure is used to open the lower drain port 232 at the bottom of the drain cylinder 23, so that the water is sprayed on the cement column 1 to keep it moisturized;

[0046] S5. The pressure generated when the hydraulic chamber 231 is filled with water drives the plug ring 24 inside it to slide upward, and triggers the electric push rod 25 on the spraying frame 2 to push the upper frame 26 to deflect, so that the upper membrane 260 opens the steel mold casing 11 to deflate, and simultaneously moves the lower membrane 270 away from the upper end surface of the cement column 1 to increase the spraying area;

[0047] S6. Under low temperature conditions at night, the water flow rate in the hose is reduced, so that after the water storage in the hydraulic chamber 231 reaches a critical value, the lower drain port 232 is automatically opened to drain water and remain stable;

[0048] S7. The lower film 270 is kept warm during the process of being attached to the upper surface of the cement column 1, and the compartment 28 formed between the upper film 260 and the lower film 270 stores heat.

[0049] Specifically, the steel mold casing 11 is usually set higher than the cement column 1. The prior art will not be described in detail here, so the spray rack 2 can easily perform moisturizing work in the elevated space, and a hanging bracket 20 is fixedly installed at the position of the drainage tube 23 of the spray rack 2, and the claw-shaped legs on the hanging bracket 20 and the steel mold casing 11 are detachably fixed by bolts and nuts, so that after the moisturizing of the cement column 1 is completed, the spray rack 2 can be transferred to the next cement column 1 for moisturizing.

[0050] Furthermore, the water delivery hose is fixed by means of the friction between its side wall and the inner wall of the pipe mouth 221, and the delivery hose is made of heat-insulating material, and the water volume is delivered and controlled by a water pump. The material of the water delivery hose, the water pump and the connection method therebetween are all existing technologies and will not be elaborated here.

[0051] Furthermore, a valve plate with a rubber ring on the edge is hingedly provided in the lower discharge port 232, and a rubber ring is also provided on the plug ring 24 to ensure the sealing effect of the piston movement. A vertical hole for the sliding of the limit plate 241 is opened on the side wall of the drain cylinder 23, and a rubber membrane petal that contacts the limit plate 241 is fixedly installed in the vertical hole to provide the drain cylinder 23 with an anti-leakage function during the movement of the limit plate 241.

[0052] Furthermore, the upper membrane 260 is fixedly installed between every two upper frames 26, and the upper membrane 260 is of the same thickness as the upper frames 26. Similarly, the lower membrane 270 is also installed in the same way and has the same thickness, so that the upper membrane 260 can keep the port of the steel mold casing 11 closed, while the lower membrane 270 can maintain a fit to the upper surface of the cement column 1.

[0053] Furthermore, a touch switch 251 (brand model HOULEX ZE-157D-1, existing technology, no further description is needed here) electrically connected to the electric push rod 25 is fixedly installed on the bracket 20, the guide rod 242 is inserted and slid on the bracket 20, and a trigger sheet 243 is fixedly installed on the guide rod 242, the upper film 260 is divided into two layers, the lower layer is a polystyrene foam insulation material layer, and the upper layer is an aluminum foil light reflection layer, and the materials are all existing technology, no further description is needed here.

[0054] Furthermore, the lower membrane 270 is specifically a cotton moisturizing cloth, which is used to improve the heat preservation and moisturizing effects of the cement column 1, and a lower rotating head 271 that rotates on the end of the drainage tube 23 is fixedly installed at the end of the lower frame 27, and a torsion spring is provided at the rotating position. A channel is also opened on the lower rotating head 271. When the lower frame 27 is pulled upward by the pull rope, the channel is connected to the hydraulic chamber 231, so as to send the dirt gathered at the bottom of the drainage tube 23 to the top of the lower membrane 270, and the end of the lower frame 27 is bent inward to form an inner arc edge 272, while the lower membrane 270 maintains the same arc-shaped lift, with the purpose of collecting the dirt discharged from the channel on the inner side of the arc-shaped lift to avoid the dirt from interfering with the molding of the cement column 1. At the same time, the lower membrane 270 can also effectively isolate the dirt from penetrating into the cement column 1, thereby improving the moisturizing effect of the cement column 1.

[0055] A large amount of water is poured into the water delivery hose during the day, so that the pressure of the water sprayed downward from the pipe mouth 221 can open the valve plate of the lower outlet 232, so that the upper end of the cement column 1 is filled with water and covered, until the water penetrates into the inside of the cement column 1 and flows downward along the side wall of the cement column 1 to complete the moisturizing work. In the process of the plug ring 24 moving up, the trigger plate 243 on the guide rod 242 presses the touch switch 251, so that the convex block at the output end of the electric push rod 25 slides against the upper frame 26 to deflect, and the upper membrane 260 The upper frame 26 moves away from the port of the steel mold casing 11 to achieve the ventilation function during the watering and moisturizing process of the cement column 1. At the same time, the heat insulation layer and the reflective layer are used to cool the compartment 28 to reduce the problem of excessive surface temperature of the cement column 1 causing a large amount of water evaporation. In the process of deflection of the upper frame 26, the lower frame 27 is pulled by the pull rope to move synchronously, so that the moisturizing cloth of the lower membrane 270 is away from the upper surface of the cement column 1, so as to ensure that the water sprayed during the day acts on the cement column 1 for moisturizing, and the water delivery softness is reduced at night. The water volume of the pipe is measured, and after the water storage in the hydraulic chamber 231 reaches a critical value, the water pressure causes the valve plate in the lower discharge port 232 to open to moisturize the cement column 1. At the same time, because the hydraulic chamber 231 maintains a stable state of water inlet and outlet, the upward plug ring 24 cannot trigger the electric push rod 25, so the lower frame 27 remains in the default state, so that the edge of the lower membrane 270 fits and covers the upper surface of the cement column 1, and the terrace area formed between the lower membrane 270 and the cement column 1 can make the water discharged from the lower discharge port 232 be stored in the area and maintain moisturizing for a long time, reducing the water consumption at night while ensuring the moisturizing effect, and the fitted lower membrane 270 provides a heat preservation function, and the partition cavity 28 forms a heat preservation chamber under the shielding effect of the upper membrane 260, so that the cement column 1 has a better heat preservation effect at night, reduces the influence of a large range of temperature changes on the hydration reaction rate of the cement column 1, and also reduces the generation of temperature stress in the cement column 1, thereby improving the moisturizing molding effect of the cement column 1.

[0056] As an embodiment further provided by the present invention, a storage shell 3 is provided at the bottom of the steel mold casing 11, and a sunshade cloth 32 covering the outer side of the entire steel mold casing 11 is provided in the storage shell 3;

[0057] A clamping head 265 is provided at the end of the upper frame 26 , and a sliding sleeve 31 which is clamped and assembled with the clamping head 265 is fixedly installed on the upper end of the sunshade cloth 32 .

[0058] Specifically, the storage shell 3 opens upward and is also installed and detachably mounted on the steel mold casing 11 by bolts and nuts, but the storage shell 3 is arranged close to the ground, and the sunshade cloth 32 is specifically made of polyester fabric commonly found on the market.

[0059] Furthermore, the end of the clamping head 265 has a trapezoidal elastic sheet, so that after the sliding sleeve 31 is inserted into the clamping head 265, it can be limited and locked by the elastic sheet. When disassembling, the elastic sheet can be pressed to make the sliding sleeve 31 slide off the elastic sheet.

[0060] After installing the spray rack 2 and the storage shell 3, multiple sliding sleeves 31 are clamped and installed on the clamping head 265, so that the sunshade cloth 32 originally stored in the storage shell 3 is pushed and pulled to be sleeved on the outside of the steel mold casing 11, so that the sunshade cloth 32 can shade the steel mold casing 11 to reduce the heat transfer to the steel mold casing 11 caused by light, thereby reducing the problem of excessive water loss in the cement column 1 and ensuring the moisturizing effect of the cement column 1.

[0061] As another embodiment further provided by the present invention, in the deflected state, the upper frame 26 makes the sliding sleeve 31 slide on the clamping head 265 and makes the upper end of the sunshade cloth 32 away from the outer side wall of the steel mold casing 11.

[0062] Specifically, the lower end of the sunshade cloth 32 is fixedly installed in the storage shell 3, so that the sunshade cloth 32 is convenient to store and also convenient to take out and use.

[0063] Furthermore, a tension spring is fixedly installed between the sliding sleeve 31 and the sunshade cloth 32 , and the tension spring is covered by the telescopic sleeve 311 , so that the sliding sliding sleeve 31 drives the tension spring to deform, thereby ensuring the safety of the sunshade cloth 32 .

[0064] During the periodic upward deflection of the upper frame 26, the movement trajectory of the clamping head 265 which is tilted at the end is made to be arc-shaped, and the sliding sleeve 31 is forced to slide down on the clamping head 265 to adapt to the arc-shaped movement trajectory, accompanied by the deformation of the tension spring, so that the upper end of the sunshade cloth 32 is actively moved away from the steel mold casing 11, so that there is an inverted triangle-shaped gap between the sunshade cloth 32 and the steel mold casing 11, thereby improving the sunshade and heat insulation effect of the sunshade cloth 32 and ensuring the moisture retention ability of the cement column 1; conversely, when the upper frame 26 drives the clamping head 265 to reset, the sliding sleeve 31 pulls the sunshade cloth 32 to fit on the steel mold casing 11, and relies on the raised edge on the steel mold casing 11 to keep a certain gap between the sunshade cloth 32 to ensure the heat insulation effect, and at night the sunshade cloth 32 plays a heat preservation function, reducing the heat loss of the steel mold casing 11 caused by the decrease in the external temperature, and reducing the temperature stress on the cement column 1.

[0065] As another embodiment further provided by the present invention, a needle tube 222 is provided at the end of the water storage cylinder 22, and the plug ring 24 moves to a high position so that the plug head 246 on it is pushed open by the needle tube 222, so that the needle tube 222 is connected to the hydraulic chamber 231;

[0066] The sunshade tube 21 conveys water in the water storage tube 22 and sprays it out through a plurality of external spray ports 211 .

[0067] Specifically, the needle tube 222 is located on the partition between the water storage cylinder 22 and the drainage cylinder 23, and the end of the needle tube 222 has a cutout for allowing water to enter. A water hole 245 is opened on the plug ring 24. The plug head 246 in the default state closes the water hole 245, and a sliding rod and a tension spring are fixedly installed on the plug head 246 with a rubber plug. The function of the plug head 246 is the same as that of the valve plate in the lower discharge port 232.

[0068] Furthermore, the upper end surface of the sunshade tube 21 is covered with a sunshade material to reduce the heating of the water in the water storage tube 22 and the drainage tube 23 caused by light, and also reduce the heating of the water supply hose. The external nozzle 211 opened on the lower end surface of the sunshade tube 21 is inclined toward the port direction of the steel mold casing 11 and is arranged in a circle, so that the water has a larger spraying area.

[0069] During the daytime water replenishment period, the plug ring 24 moves upward, the end of the needle tube 222 pushes the plug head 246 downward, and the needle tube 222 is connected to the hydraulic chamber 231, so that a large amount of water enters the water storage cylinder 22 from the needle tube 22, and the water in the water storage cylinder 22 is directly transported to the sunshade cylinder 21, and sprayed above the upper membrane 260 under the action of multiple external nozzles 211, so that the water cools the area above the upper membrane 260, reduces the temperature rise caused by the temperature in the compartment 28, and improves the thermal insulation effect of the compartment 28.

[0070] As another embodiment further provided by the present invention, a transfer chamber 233 opened and closed by a plug head 246 is further provided in the drain cylinder 23, and an upper transfer head 261 connected to the transfer chamber 233 is provided at the end of the upper frame 26;

[0071] A water channel 262 connected to the upper rotating head 261 is provided in the upper frame 26 , and an atomizing frame 264 for spraying water into the compartment 28 by atomization is provided in the water channel 262 .

[0072] Specifically, the transfer chamber 233 is located between the plug ring 24 and the partition plate, the upper turn head 261 is a columnar shell at the rotation position of the upper frame 26, and the upper turn head 261 has a torsion spring at the rotation position.

[0073] Furthermore, the lower end surface of the atomizing frame 264 has a plurality of atomizing heads, while the upper surface is connected to the water channel 262, and the atomizing frame 264 is limited and guided by the slide rod in the water channel 262, and a tension spring arranged in an annular manner on the outside of the slide rod is fixedly installed between the atomizing frame 264 and the water channel 262, and in the default state of the tension spring, the atomizing head is extended from the hole opened on the lower surface of the upper frame 26, so that the atomizing head can atomize and drain water in the compartment 28, and a rubber membrane flap is fixedly installed in the hole to provide sealing after the atomizing head is retracted.

[0074] The hydraulic chamber 231 and the transfer chamber 233 are connected by opening the plug 246, and the transfer chamber 233 is connected with the opening on the upper rotating head 261, so that the water gradually filled in the transfer chamber 233 enters the water channel 262, and is injected into the atomizing head through the back of the atomizing frame 264, and then atomized water is sprayed into the compartment 28 through the atomizing head, so that a large amount of water mist is suspended in the compartment 28 to achieve the purpose of cooling, so as to offset the temperature rise after the upper membrane 260 opens the steel mold casing 11, and avoid interference with the moisturizing of the cement column 1 during the opening and closing process of the upper frame 26.

[0075] As another embodiment further provided by the present invention, an inner nozzle 263 communicating with the inner side of the sunshade cloth 32 is provided at the end of the water channel 262 .

[0076] Specifically, the position of the inner nozzle 263 exceeds the diameter of the steel mold casing 11 , and the end of the inner nozzle 263 is located between the steel mold casing 11 and the sunshade cloth 32 , so that water can easily enter the inner side of the sunshade cloth 32 .

[0077] The water in the water channel 262 gradually climbs upward along the upper frame 26, and is discharged downward when it climbs to the high position of the inner nozzle 263, so that the water flows downward on the inner wall of the sunshade cloth 32. On the one hand, it can cool the sunshade cloth 32, and on the other hand, the remaining water gathers in the storage shell 3, so that the water stored in the storage shell 3 evaporates slowly, which is used to reduce the temperature of the outside of the steel mold casing 11, so that the cement column 1 close to the ground can be better cooled, thereby increasing the overall thermal insulation effect of the cement column 1.

[0078] As another embodiment further provided by the present invention, the upper membrane 260 in the active state cooperates with the water storage cylinder 22 to enable the needle tube 222 to discharge water toward the plug 246.

[0079] By keeping the light on in the evening and reducing the flow rate in the water hose during regular spraying, the water added to the water storage cylinder 22 is no longer sprayed out from the outer nozzle 211, that is, in order to cope with the night state, the upper membrane 260 is no longer sprayed. At the same time, the upper frame 26 continues to deflect so that the reflective layer of the upper membrane 260 gathers the light and irradiates and heats the water in the water storage cylinder 22. The plug ring 24 no longer moves up to be hit by the needle tube 222 to open the plug 246, but the water pre-stored in the water storage cylinder 22 drips into the transfer chamber 233 through the needle tube 222 after being heated, and the transfer chamber 233 is gradually filled with hot water until the water reaches the critical value of the plug 246 and then opens to mix the hot water into the hydraulic chamber 231, so that the water discharged from the lower outlet 232 to the upper end face of the cement column 1 is in a warm state, thereby alleviating the temperature stress of the cement column 1 in the evening and making the cement column 1 more effective in moisturizing at night.

[0080] As another embodiment further provided by the present invention, a trigger head 244 that pushes and cooperates with the atomization frame 264 is disposed at the end of the guide rod 242 , and the water channel 262 flows back the discharged water of the needle tube 222 .

[0081] Specifically, a hole is formed on the lower end surface of the upper frame 26 for the trigger head 244 to move, and a rubber membrane is fixedly installed in the hole to provide sealing after the trigger head 244 is inserted into the hole.

[0082] Furthermore, the spacing between the atomizing heads is larger than the sliding range of the protrusion at the output end of the electric push rod 25, so as to ensure the normal atomization and drainage work of the atomizing frame 264.

[0083] When the upper frame 26 is pushed to deflect by the electric push rod 25, the trigger head 244 is forced to detach from the lower end surface of the upper frame 26. At night, when the plug ring 24 is filled with water in the hydraulic chamber 231 and reaches a critical value, the guide rod 242 moves up with the plug ring 24. At this time, the trigger sheet 243 that cannot move to the highest position cannot trigger the touch switch 251 to work. Therefore, during the upward movement of the trigger head 244, it can push the atomizing frame 264 to move in the waterway 262, and make the back of the atomizing frame 264 touch the side wall of the waterway 262 to close, accompanied by the atomizing head retracting into the waterway 262, and the hot water in the transfer chamber 233 enters the waterway 262 through the long-term connected upper transfer head 261, so that the hot water climbs upward in the waterway 262 and flows, and rinses the retracted atomizing head, so as to reduce the blockage problem of the atomizing head during atomization, and ensure the cooling efficiency of the partition chamber 28 under daytime conditions.

[0084] As another embodiment further provided by the present invention, the backflow water in the water channel 262 is discharged from the inner nozzle 263 and gathered in the storage shell 3.

[0085] The hot water that enters the water channel 262 at night is discharged downward when it reaches the inner nozzle 263 and gathers in the storage shell 3 again. At this time, the hot water stored in the storage shell 3 can be insulated from the outside of the steel mold casing 11 to reduce the temperature loss at night. At the same time, the pre-stored water can provide cooling treatment under the temperature rising conditions in the early morning, thereby ensuring the overall temperature balance of the cement column 1 during the moisturizing period and improving the moisturizing efficiency.

[0086] As another embodiment further provided by the present invention, the outer nozzle 211 drips water onto the surface of the upper film 260 and gathers at the position of the upper rotor 261 .

[0087] The hot water in the water storage cylinder 22 is gradually discharged downwards through the needle tube 222. During this period, the needle tube 222 needs to be ventilated for drainage, so that the outer nozzle 211 pumps air to the outside. During the ventilation process, the outer nozzle 211 drips the hot water remaining in the sunshade cylinder 21 downwards, so that this part of the hot water carries the residual heat on the upper film 260 and gathers at the position of the upper rotating head 261, which is used to insulate the outside of the drainage cylinder 23, thereby achieving the purpose of efficient use of heat, reducing the temperature stress of the cement column 1 at night, and improving the moisturizing effect.

[0088] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
