[0042] See also Figure 1 、 Figure 2 as well as Figure 3This embodiment provides a concrete curing device, including a support plate 10, an annular water tank 20, a water pressure assembly 40, a drive assembly 50, and a water supply assembly (not shown in the figure). The water supply assembly is used to supply water to the interior of the annular water tank 20. The support plates 10 are provided in four groups, and the annular water tank 20 is arranged inside the four groups of support plates 10. The water pressure assembly 40 is movably arranged inside the annular water tank 20 to apply pressure to the water source inside the annular water tank 20 so that the water source contacts the four side walls of the concrete column 30. The drive assembly 50 is arranged outside the annular water tank 20 to drive the annular water tank 20 to intermittently move downward along the outside of the concrete column 30.

[0043] Initially, the annular water storage tank 20 is located at the upper end of the inner side of the four sets of support plates 10. When the concrete column 30 needs to be watered and maintained, the annular water storage tank 20 and the four sets of support plates 10 can be lifted with the help of a lifting machine (not shown in the figure), so that the annular water storage tank 20 is sleeved on the outside of the concrete column 30 from the upper end of the concrete column 30. At this time, the four sets of support plates 10 are respectively supported on the outer sides of the four side walls of the concrete column 30 (such as Figure 1 As shown), the water supply component then supplies water to the inside of the annular water storage tank 20, and the water pressure component 40 applies pressure to the water source inside the annular water storage tank 20, so that the water source contacts the four side walls of the concrete column 30 to ensure that the water source can fully penetrate into the interior of the concrete column 30, thereby watering and curing the area of ​​the concrete column 30 currently surrounded by the annular water storage tank 20. After the watering and curing of the current area is completed, the driving component 50 drives the annular water storage tank 20 to move down one position along the outside of the concrete column 30, and then the water supply component again supplies water to the annular water storage tank 20 internal water supply, the water pressure component 40 again applies pressure to the water source, so that the water source contacts the four side walls of the concrete column 30 currently surrounded by the annular water storage tank 20, to ensure that the water source can fully penetrate into the interior of the concrete column 30 again, so that the area of ​​the concrete column 30 currently surrounded by the annular water storage tank 20 is watered and maintained again, and such a reciprocating cycle can realize segmented watering and maintenance of the concrete column 30, thereby improving the uniformity of watering of the concrete column 30, improving the maintenance effect, and reducing the waste of water resources.

[0044] See also Figure 1 、 Figure 2 as well as Figure 3 In one embodiment, the annular water tank 20 includes an annular enclosure 201, a top plate 202 and a bottom plate 206. The top plate 202 is fixedly arranged at the upper end of the annular enclosure 201, and the bottom plate 206 is fixedly arranged at the lower end of the annular enclosure 201. The center positions of the top plate 202 and the bottom plate 206 are both provided with openings 207 for the concrete column 30 to pass through.

[0045] The annular water tank 20 is lifted by a lifting machine so that the annular water tank 20 is located as a whole directly above the concrete column 30. The annular water tank 20 is then lowered by the lifting machine. The upper end of the concrete column 30 can pass through the openings 207 on the bottom plate 206 and the top plate 202, and the annular enclosure 201 is sleeved on the outside of the concrete column 30.

[0046] See also Figure 2 In one embodiment, the water pressure assembly 40 includes a movable pressure plate 401, a guide rod 403, a first elastic member 404 and a connecting rod 405. The movable pressure plate 401 is provided with four groups. The four groups of movable pressure plates 401 are movably arranged on the inner side of the annular enclosure 201. The upper ends of the four groups of movable pressure plates 401 are in contact with the top plate 202, and the lower ends are in contact with the bottom plate 206. The four groups of movable pressure plates 401 form a rectangular structure. A flexible water retaining layer 402 is passed between two adjacent groups of movable pressure plates 401. The outer side of each group of movable pressure plates 401 is fixed with the connecting rod 405 and the guide rod 403, and the connecting rod 405 and the guide rod 403 extend through the annular enclosure 201 at one end away from the corresponding movable pressure plate 401 and cooperate with the annular enclosure 201. The outer side of each group of movable pressure plates 401 is connected to the inner wall of the annular enclosure 201 through a group of the first elastic members 404, and the first elastic members 404 are used to provide elastic support for the movable pressure plates 401.

[0047] When the annular enclosure 201 is sleeved on a certain area outside the concrete column 30, the four groups of movable pressure plates 401 correspond to the four side walls of the concrete column 30 one by one, and the water supply component supplies water to the area between the four groups of movable pressure plates 401 and the concrete column 30. Through the elastic support of the first elastic member 404 on the movable pressure plates 401, the four groups of movable pressure plates 401 generate pressure on the water source to press the water source onto the four side walls of the concrete column 30, so that the water source can quickly penetrate into the interior of the concrete column 30 from the four side walls of the concrete column 30, thereby completing the watering and curing operation of the current area of ​​the concrete column 30; as the water source penetrates into the interior of the concrete column 30, the four groups The water source between the movable pressure plate 401 and the concrete column 30 is constantly decreasing, and the first elastic member 404 can push the movable pressure plate 401 so that the movable pressure plate 401 is continuously moved toward the concrete column 30 to continue to apply pressure to the remaining water source. The pressurized water source can always cover the entire current side wall surface of the concrete column 30, thereby avoiding the reduction of the water source liquid level due to the reduction of the water source and achieving uniform wetting of the current area of ​​the concrete column 30; when the four groups of movable pressure plates 401 approach the concrete column 30, the flexible water retaining layer 402 between the two adjacent groups of movable pressure plates 401 is adaptively deformed, thereby enclosing the entire water source between the four groups of movable pressure plates 401 and the concrete column 30.

[0048] See also Figure 1、 Figure 2 as well as Figure 4 In one embodiment, the support plate 10 is provided with a plurality of horizontal slide grooves 101 and a plurality of inclined slide grooves 102, and the plurality of horizontal slide grooves 101 are spaced apart along the height direction of the support plate 10, and the plurality of inclined slide grooves 102 are alternately arranged between the plurality of horizontal slide grooves 101, and the plurality of inclined slide grooves 102 are used to connect the plurality of horizontal slide grooves 101 end to end, and the driving assembly 50 includes a U-shaped plate 501 and a pin rod 502, the U-shaped plate 501 is fixedly arranged at one end of the connecting rod 405 located outside the annular enclosure 201, the U-shaped plate 501 is clamped on opposite sides of the support plate 10, the pin rod 502 is arranged on the inner side of the U-shaped plate 501, and the pin rod 502 passes through the inclined slide groove 102 and the horizontal slide groove 101.

[0049] Initially, the pin rod 502 passes through the uppermost set of horizontal slide grooves 101. After the hoisting machinery lifts the annular water storage tank 20 and sets the annular water storage tank 20 on the outer portion of the upper end of the concrete column 30, the water supply assembly supplies water between the four sets of movable pressure plates 401 and the concrete column 30. The four sets of movable pressure plates 401 exert pressure on the water source under the elastic support of their respective corresponding first elastic members 404, so that the water source penetrates into the interior of the concrete column 30 from the four side walls of the concrete column 30, thereby achieving watering and wetting of the current area of ​​the concrete column 30. During this process, the first elastic member 404 pushes the movable pressure plate 401 close to the concrete column 30, and the movable pressure plate 401 drives the connecting rod 40 5 makes the connecting rod 405 move toward the inside of the annular enclosure 201, and the connecting rod 405 drives the U-shaped plate 501 to move synchronously. When the U-shaped plate 501 moves, it drives the pin rod 502 so that the pin rod 502 slides along the inner side of the uppermost set of horizontal chutes 101. When the water source on one side of the movable pressure plate 401 completely penetrates into the interior of the concrete column 30, the movable pressure plate 401 contacts the corresponding side wall of the concrete column 30, and at the same time, the pin rod 502 slides to one end of the uppermost horizontal chute 101, and then slides from one end of the horizontal chute 101 into the interior of the lower inclined chute 102 and slides down along the interior of the lower inclined chute 102. The annular water storage tank 20 moves downward along the outer side of the concrete column 30 due to its own gravity, and the pin rod 502 slides along the inner side of the uppermost set of horizontal chute 101. When 02 slides down the inclined chute 102, it pulls the U-shaped plate 501 and then pulls the connecting rod 405, so that the connecting rod 405 moves to the outside of the annular panel 201, and the connecting rod 405 pulls the movable pressure plate 401 so that the movable pressure plate 401 is away from the concrete column 30, and the corresponding first elastic member 404 is compressed until the pin rod 502 slides from the inclined chute 102 into the second set of horizontal chute 101 above, the pin rod 502 stops moving down, and the annular water tank 20 stops moving down synchronously. At this time, the annular water tank 20 moves down one position along the outside of the concrete column 30, and then the water supply component supplies water to the area between the four sets of movable pressure plates 401 and the concrete column 30 again. Component 404 pushes the movable pressure plate 401 so that the movable pressure plate 401 approaches the concrete column 30 again, so as to press the water source toward the concrete column 30 again, thereby realizing re-watering and wetting of the current area of ​​the concrete column 30. After the current area of ​​the concrete column 30 is watered and wetting, the pin rod 502 slides from the inside of the upper set of horizontal slide grooves 101 into the inside of the lower set of inclined slide grooves 102 and slides down along the inside of the lower set of inclined slide grooves 102. The annular water tank 20 moves down one position again along the outside of the concrete column 30... This reciprocating cycle can make the annular water tank 20 intermittently move down along the outside of the concrete column 30, thereby realizing the segmented watering and wetting treatment of the concrete column 30.

[0050] See also Figure 1 In one embodiment, a water inlet pipe 204 is provided on the top plate 202 , and one end of the water inlet pipe 204 away from the top plate 202 is connected to the water supply assembly.

[0051] When the pin rod 502 slides from a certain set of inclined slides 102 into the horizontal slide 101 below, the water supply assembly supplies water to the inner side of the annular enclosure 201, that is, the area between the four sets of movable pressure plates 401 and the concrete column 30, through the water inlet pipe 204, thereby replenishing the water source.

[0052] In one embodiment, the water supply component may be a water pump or other structure with water supply function, which is not limited here.

[0053] See also Figure 6 In one embodiment, an external thread 503 is provided at one end of the pin rod 502, and a threaded hole (not shown in the figure) adapted to the external thread 503 is opened on the inner wall of one of the plates of the U-shaped plate 501.

[0054] After the annular water tank 20 moves down to the bottom along the outside of the concrete column 30 and the entire concrete column 30 is watered and moistened, the lifting machinery lifts the annular water tank 20 and the four groups of support plates 10, so that the annular water tank 20 is removed from the outside of the concrete column 30. Then the staff rotates the pin rod 502 so that the end of the pin rod 502 with the external thread 503 is removed from the inside of the threaded hole, and then the pin rod 502 is pulled out of the inside of the lowest group of horizontal slide grooves 101, and then the annular water tank 20 is moved upward to move the annular water tank 20 again to the upper position between the four groups of support plates 10, and then the pin rod 502 is pushed again so that the pin rod 502 passes through the inside of the uppermost horizontal slide groove 101, and finally the pin rod 502 is rotated in the opposite direction so that the end of the pin rod 502 with the external thread 503 is screwed back into the corresponding threaded hole, thereby realizing the reset of the annular water tank 20.

[0055] See also Figure 1 as well as Figure 2 In one embodiment, an annular sealing airbag 203 is provided on the bottom plate 206 and the opening 207 at the center of the top plate 202.

[0056] When the concrete column 30 passes through the openings 207 on the bottom plate 206 and the top plate 202, the provision of the annular sealing airbag 203 can improve the sealing effect between the top plate 202 and the bottom plate 206 and the concrete column 30, so that when the movable pressure plate 401 applies pressure to the water source, it can prevent the water source from leaking from the gaps between the concrete column 30 and the top plate 202 and the bottom plate 206, thereby ensuring that the water source can smoothly penetrate into the interior of the concrete column 30 and prevent the water source from flowing out.

[0057] See also Figure 3In one embodiment, an air extraction component 60 is provided inside the top plate 202 and the bottom plate 206. When the water source between the movable pressure plate 401 and the concrete column 30 penetrates into the interior of the concrete column 30, the air extraction component 60 is used to extract the air inside the annular sealing airbag 203, causing the annular sealing airbag 203 to collapse, so that the annular water tank 20 can smoothly move downward along the outside of the concrete column 30.

[0058] See also Figure 2 、 Figure 5 as well as Figure 7 In one embodiment, the bottom plate 206 and the side wall of the top plate 202 are both provided with a first conductive rod 205, and two groups of second conductive rods 406 are provided on one side of the movable pressure plate 401, wherein one group of the second conductive rods 406 has one end away from the movable pressure plate 401 in contact with the bottom plate 206, and the other group of the second conductive rods 406 has one end away from the movable pressure plate 401 in contact with the top plate 202, and the two groups of the second conductive rods 406 are connected to an external power supply (not shown in the figure) through a wire (not shown in the figure), and the bottom plate 206 and the top plate 202 are both provided with a connection to the corresponding annular sealing airbag 203. The air storage channel 208 is connected, and the air extraction component 60 includes a permanent magnet 601, a second elastic member 602, an electromagnet 603 and a plunger rod 604. The permanent magnet 601 is fixedly arranged inside the air storage channel 208, and the plunger rod 604 is movably arranged inside the air storage channel 208. The electromagnet 603 is fixedly arranged at one end of the plunger rod 604 and is distributed relative to the permanent magnet 601. One end of the second elastic member 602 is connected to the permanent magnet 601, and the other end is connected to the electromagnet 603, which is used to provide elastic support for the electromagnet 603. The electromagnet 603 is in contact with the first conductive rod 205.

[0059] When the water source between the movable pressure plate 401 and the concrete column 30 penetrates into the interior of the concrete column 30, the movable pressure plate 401 contacts the side wall of the concrete column 30 under the support of the first elastic member 404, and the two groups of second conductive rods 406 on the side wall of the movable pressure plate 401 contact the first conductive rods 205 on the top plate 202 and the bottom plate 206 respectively. At this time, the external power supply supplies power to the electromagnet 603 through the wire, the second conductive rods 406 and the first conductive rods 205, and the electromagnet 603 generates magnetism and then attracts the permanent magnet 601. Since the permanent magnet 601 is fixedly installed inside the air storage channel 208, the permanent magnet 601 attracts the electromagnet 603 and then pulls the plunger rod 604, causing the plunger rod 604 to move along the inside of the air storage channel 208, so as to extract the air inside the annular sealing airbag 203 into the air storage channel 208, causing the annular sealing airbag 203 to collapse and then contact the concrete column 3 0 side wall is separated so that the annular water storage tank 20 can smoothly move down along the outside of the concrete column 30; when the annular water storage tank 20 starts to move down along the outside of the concrete column 30, as the pin rod 502 slides down along the inside of the inclined slide groove 102, the pin rod 502 pulls the movable pressure plate 401 so that the movable pressure plate 401 is away from the concrete column 30. At this time, the second conductive rod 406 on the side wall of the movable pressure plate 401 is separated from the first conductive rod 205, the electromagnet 603 is powered off and demagnetized, and the second elastic member 602 pushes the electromagnet 603 to make the plunger rod 604 move in the opposite direction along the inside of the air storage channel 208, so as to reversely press the air inside the air storage channel 208 into the inside of the annular sealing airbag 203, so that the annular sealing airbag 203 is inflated. When the annular water storage tank 20 moves down one position, the annular sealing airbag 203 re-expands the side wall of the concrete column 30, thereby achieving re-sealing of the concrete column 30 with the bottom plate 206 and the top plate 202.

[0060] In one embodiment, the flexible water-retaining layer 402 may be a rubber layer or a plastic layer, which is not limited here.

[0061] In one embodiment, the first elastic member 404 and the second elastic member 602 may be springs or metal springs, which are not limited herein.

[0062] In the embodiment of the present invention, initially, the annular water storage tank 20 is located at the upper end of the inner side of the four sets of support plates 10. When the concrete column 30 needs to be watered and maintained, the annular water storage tank 20 and the four sets of support plates 10 can be lifted by means of a lifting machine (not shown in the figure), so that the annular water storage tank 20 is sleeved on the outside of the concrete column 30 by the upper end of the concrete column 30. At this time, the four sets of support plates 10 are respectively supported on the outer sides of the four side walls of the concrete column 30 (such as Figure 1As shown), the water supply component then supplies water to the inside of the annular water tank 20, and the water pressure component 40 applies pressure to the water source inside the annular water tank 20, so that the water source contacts the four side walls of the concrete column 30 to ensure that the water source can fully penetrate into the concrete column 30, thereby watering and curing the area of ​​the concrete column 30 currently surrounded by the annular water tank 20. After the watering and curing of the current area is completed, the driving component 50 drives the annular water tank 20 to move down one position along the outside of the concrete column 30, and then the water supply component again supplies water to the inside of the annular water tank 20, and the water pressure component 40 again applies pressure to the water source, so that the water source and the concrete column 30 currently surrounded by The four side walls surrounded by the annular water tank 20 are in contact to ensure that the water source can fully penetrate into the interior of the concrete column 30 again, so that the area of ​​the concrete column 30 currently surrounded by the annular water tank 20 is watered and maintained again. Such a reciprocating cycle can realize segmented watering and maintenance of the concrete column 30, thereby improving the uniformity of watering of the concrete column 30, improving the maintenance effect, and reducing the waste of water resources. Compared with the existing technology, segmented watering and maintenance can be performed on longer concrete columns 30, thereby greatly reducing the waste of water resources, achieving uniform watering of the concrete column 30, and improving the maintenance effect of the concrete column 30.
