Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to an automatic cooling device for a condensation cycle of large-volume concrete. Background Art

[0002] With the vigorous construction of local new areas in my country, various types of super-high-rise buildings have ushered in a climax in their development. The amount of foundation concrete used ranges from several thousand to tens of thousands of cubic meters. Due to the large volume of concrete and the high amount of cement used, the hydration heat of cement will cause the internal temperature of the concrete to rise significantly after pouring, and the maximum temperature can reach 90°C. The heat dissipated on the surface of the concrete is relatively fast, forming a temperature difference between the inside and outside. When the absolute temperature difference between the inside and outside exceeds 25°C, temperature cracks will appear inside and on the surface of the concrete. As the age of the concrete increases, these cracks gradually develop into through cracks, which directly reduce the strength and durability of the structure and affect the structural safety of the building.

[0003] At present, there are two methods for controlling the temperature of large-volume concrete: the first is the raw material control method, which reduces the temperature generated by the hydration heat of concrete by selecting low-heat Portland cement, slag cement, etc., or controls the adiabatic temperature rise and mold entry temperature of concrete by optimizing the concrete mix ratio and lowering the mixing temperature. However, the cost of selecting low-hydration heat cement such as low-heat Portland cement, slag cement, etc. is relatively high.

[0004] The second method is to arrange transverse pre-buried cooling water pipes, which use cold water to absorb the hydration heat of concrete and control the maximum temperature of the concrete. However, during use, due to the arrangement of transverse pre-buried cooling water pipes, the pre-buried cooling water pipes cannot be recycled after cooling and can only be pre-buried in the concrete, resulting in increased costs; at the same time, since the transverse pre-buried cooling water pipes are evenly arranged in the concrete, several transverse pre-buried cooling water pipes can only cool down the positions where they are located, while the temperature of other positions of the concrete cannot be cooled, resulting in poor cooling effect of the entire concrete.

[0005] Therefore, conducting in-depth research on large-volume concrete temperature control technology and proposing reasonable preventive measures and solutions have become technical issues that technical personnel in this field urgently need to solve in order to promote the development speed of my country's construction technology and improve the quality of projects. Summary of the Invention

[0006] The present invention aims to provide an automatic cooling device for the condensation cycle of large-volume concrete, which can realize directional transportation according to the hydration heat of large-volume concrete, cool the hydration heat of large-volume concrete, and after cooling, it can be reset in the reverse direction along the directional transportation line, thereby realizing reuse.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] 1) Automatic cooling device for large volume concrete condensation cycle, including:

[0009] The multi-zone concrete unit is configured to divide a large volume of concrete into a plurality of single-zone concrete zones. The hydration heat generated in each single-zone concrete zone is set in a specified direction. A movable cooling water pipe is placed in the single-zone concrete zone, and the cooling water pipe moves in the single-zone concrete zone in a guided manner.

[0010] The directional drive module located within the single-zone concrete is configured to include a moving head disposed at the end of a cooling water pipe. The moving head drives the cooling water pipe to move within the single-zone concrete in a specified direction. The end of the moving head includes a detection terminal for determining the hydration heat area generated within the single-zone concrete. The moving head also includes a recording terminal for recording the movement trajectory of the cooling water pipe.

[0011] The microprocessor is configured to be electrically connected to the directional drive modules in each single-area concrete, receive the detection end of the moving head to determine the hydration heat area generated in the single-area concrete, control the moving head of the directional drive module to drive the cooling water pipe to move in the single-area concrete in a specified direction based on the data information transmitted by the detection end, receive the recording end of the moving head to collect the movement track of the cooling water pipe in real time, and reversely drive the moving head to reset the movement track.

[0012] The multi-region concrete unit of the above technical solution is used to sequentially classify the large volume concrete into several single-region concretes, so that the large volume concrete can be cooled in blocks, so that each position of the large volume concrete can be cooled evenly, thereby improving the overall cooling effect of the large volume concrete.

[0013] At the same time, a directional drive module is set in the single-area concrete. The directional drive module can drive the cooling water pipe to move in the single-area concrete. During the movement of the cooling water pipe in the single-area concrete, on the one hand, it drives the concrete attached to the cooling water pipe to shift, thereby further realizing the stirring effect. On the other hand, the cooling water pipe can cool down the hydration heat area generated by the concrete on the surrounding side during the movement, thereby ensuring the cooling effect of large-volume concrete.

[0014] The moving head arranged in the directional area module has a moving function. The detection end at the end of the moving head is used to determine the hydration heat area generated by the single-area concrete. After determining the position of the hydration heat area generated by the single-area concrete, the information is sent to the microprocessor. The microprocessor sends an instruction to the directional area module to drive the moving head to move toward the hydration heat area generated by the single-area concrete, so that the hydration heat area generated by the single-area concrete is the specified direction of movement of the moving head. In this way, the hydration heat area generated by the single-area concrete can be cooled in a fixed and directional manner, thereby improving the overall cooling effect of the large-volume concrete.

[0015] By setting the hydration heat generated by each single area of ​​concrete as the specified direction, the microprocessor is used to receive the data information of the hydration heat area generated in the single area of ​​concrete sent by the detection end. The microprocessor sends an instruction to the moving head with the data information as the specified direction, driving the cooling water pipe to move toward the hydration heat area generated in the one-way area concrete, and receiving the recording end of the moving head to collect the moving track of the cooling water pipe in real time, and reversely drive the moving head to reset the moving track, so that the cooling water pipe can be driven back to the initial position along the moving track, so that it can be reused.

[0016] 2) The automatic cooling device for large-volume concrete condensation cycle according to 1), wherein:

[0017] The moving head has a hollow structure and is provided with a partition inside the moving head. The partition divides the internal space of the moving head into an upper space and a lower space. The upper space is connected to the cooling water pipe and has condensed water inside the upper space. The lower space has a driving member for driving the moving head to move.

[0018] By adopting the above technical solution, the upper space of the moving head is connected with the cooling water pipe, so that the condensed water in the cooling water pipe flows into the upper space, making the temperature of the moving head itself lower, which can protect the moving head from being affected by the high temperature of hydration heat generated by the concrete in a single area. At the same time, since the upper space is located above the lower space, the heat generated by the driving part in the lower space during the process of driving the moving head to move will also be taken away by the flowing condensed water in the upper space, thereby ensuring the normal operation of the driving part and extending its service life.

[0019] 3) The automatic cooling device for large-volume concrete condensation cycle according to 2), wherein:

[0020] The driving member includes a bidirectional motor fixed in the lower space, and the two ends of the bidirectional motor respectively have a first output shaft and a second output shaft extending outward, the free end of the first output shaft is rotatably connected to the first rotating shaft, and the end of the first rotating shaft away from the first output shaft is connected to the first spiral fan, the free end of the second output shaft is rotatably connected to the second rotating shaft, and the end of the second rotating shaft away from the second output shaft is connected to the second spiral fan.

[0021] The first output shaft and the second output shaft of the bidirectional motor in the above technical solution rotate in opposite directions, so that when the first output shaft drives the first rotating shaft to rotate in the forward direction, it also drives the first spiral fan to rotate in the forward direction and pushes the concrete in front of the moving head. At the same time, the second output shaft drives the second rotating shaft to rotate in the reverse direction, and at the same time drives the second spiral fan to rotate in the reverse direction to generate negative pressure and push the moving head forward, thereby ensuring that the moving head can move in a direction within a single area of ​​concrete.

[0022] 4) The automatic cooling device for condensation cycle of large-volume concrete according to 3), wherein:

[0023] The first spiral fan includes a first swing shaft, one end of the first swing shaft is rotatably connected to the first rotating shaft through a first torque disk, the end of the first swing shaft away from the first rotating shaft is connected to the first fan group, and a first left telescopic pump and a first right telescopic pump are respectively provided on both sides of the first rotating shaft, the first left telescopic pump has a first left telescopic rod toward and pushing the first swing shaft to move to the right, and the first right telescopic pump has a first right telescopic rod toward and pushing the first swing shaft to move to the left, so that the first swing shaft swings left and right along the width direction of its moving head with the first torque disk as the center point.

[0024] In the above technical solution, the first swing shaft is rotatably connected to the first rotating shaft via the first torque disk, so that the first swing shaft rotates around the first torque disk as the center point. During the rotation, the first swing shaft changes the rotation angle of the first fan group, thereby realizing the movement direction of the moving head driven by the first fan group; this technical solution uses the first left telescopic pump and the first right telescopic pump to push the first swing shaft to rotate around the first torque disk, thereby driving the first swing shaft to rotate and changing the direction of its moving head.

[0025] Since the first left telescopic pump is based on the left and right sides of the first rotating axis and is located on the left side of the moving head, during use, when the first left telescopic rod of the first left telescopic pump is extending and retracting, the first left telescopic rod pushes the first swing axis to the right based on the right side of the first rotating axis, thereby changing the first fan group to tilt toward the right and thus changing the moving direction of the moving head; since the first right telescopic pump is based on the left and right sides of the first rotating axis and is located on the right side of the moving head, therefore, during use, when the first right telescopic rod of the first right telescopic pump is extending and retracting, the first right telescopic rod pushes the first swing axis to the left based on the right side of the first rotating axis, thereby changing the first fan group to tilt toward the left and thus changing the moving direction of the moving head.

[0026] 5) The automatic cooling device for large-volume concrete condensation cycle according to 3), wherein:

[0027] The second spiral fan includes a second swing shaft, the two ends of the second swing shaft are rotatably connected to the second rotating shaft through a second torque disk, the end of the second swing shaft away from the second rotating shaft is connected to a second fan group, and a second left telescopic pump and a second right telescopic pump are respectively provided on both sides of the second rotating shaft, the second left telescopic pump has a second left telescopic rod toward and pushes the second swing shaft to move to the right, and the second right telescopic pump has a second right telescopic rod toward and pushes the second swing shaft to move to the left, so that the second swing shaft swings left and right along the width direction of its moving head with the second torque disk as the center point.

[0028] The second swing shaft in the above-mentioned technical solution is rotatably connected to the second rotating shaft via the second torque disk, so that the second swing shaft rotates around the second torque disk as the center point. During the rotation, the second swing shaft changes the rotation angle of the second fan group, thereby realizing the movement direction of the moving head driven by the second fan group; this technical solution uses a second left telescopic pump and a second right telescopic pump to push the second swing shaft to rotate around the second torque disk, thereby driving the second swing shaft to rotate and changing the direction of its moving head.

[0029] Since the second left telescopic pump is based on the left and right of the second rotating axis and is located on the left side of the moving head, during use, the second left telescopic rod of the second left telescopic pump pushes the second swing axis to the right based on the right side of the second rotating axis, thereby changing the second fan group to tilt toward the right and thus changing the moving direction of the moving head; since the second right telescopic pump is based on the left and right of the second rotating axis and is located on the right side of the moving head, therefore, during use, the second right telescopic rod of the second right telescopic pump pushes the second swing axis to the left based on the right side of the second rotating axis, thereby changing the second fan group to tilt toward the left and thus changing the moving direction of the moving head.

[0030] 6) The automatic cooling device for large-volume concrete condensation cycle according to 4), wherein:

[0031] The first left telescopic pump and the first right telescopic pump are both inclined and face the first swing axis respectively. The free end of the first left telescopic rod and the free end of the first right telescopic rod are respectively provided with a triangular first soft colloid, and the inclined surface of the first soft colloid is parallel to the side of the first swing axis.

[0032] In the above technical solution, the first left telescopic pump and the first right telescopic pump are both arranged at an angle, so that the first left telescopic rod and the first right telescopic rod are inclined toward the first swing axis. At the same time, the first soft colloids on the free ends of the first left telescopic rod and the free ends of the first right telescopic rod are respectively in contact with the first swing axis. The inclined surface of the first soft colloid is parallel to the side surface of the first swing axis so that the inclined surface of the first soft colloid pushes the first swing axis to change its rotation direction.

[0033] 7) The automatic cooling device for large-volume concrete condensation cycle according to 5), wherein:

[0034] The second left telescopic pump and the second right telescopic pump are both inclined and face the second swing axis respectively. The free end of the second left telescopic rod and the free end of the second right telescopic rod are respectively provided with a triangular second soft colloid, and the inclined surface of the second soft colloid is parallel to the side of the second swing axis.

[0035] In the above technical solution, the second left telescopic pump and the second right telescopic pump are both arranged at an angle, so that the second left telescopic rod and the second right telescopic rod are inclined toward the second swing axis. At the same time, the second soft colloids on the free ends of the second left telescopic rod and the free ends of the second right telescopic rod are in contact with the second swing axis respectively. The inclined surface of the second soft colloid is parallel to the side surface of the second swing axis, so that the inclined surface of the second soft colloid pushes the second swing axis to change its rotation direction.

[0036] 8) The automatic cooling device for large-volume concrete condensation cycle according to 4), wherein:

[0037] The first fan group includes a first rotating sleeve, which is fixed to the end of the first swing shaft away from the first rotating shaft. The second fan group includes a second rotating sleeve, which is fixed to the end of the second swing shaft away from the second rotating shaft. The first rotating sleeve and the second rotating sleeve are evenly distributed with a plurality of rotating blades along their axial direction.

[0038] In the above technical solution, the first rotating sleeve is used to connect the rotating blades and the first swing shaft, so that when the first swing shaft rotates with the first rotating shaft, it drives several rotating blades evenly distributed in the circumferential direction of the first rotating sleeve to rotate to push the concrete in front of the moving head; the second rotating sleeve is used to connect the rotating blades and the second swing shaft, so that when the second swing shaft rotates with the second rotating shaft, it drives several rotating blades evenly distributed in the circumferential direction of the second rotating sleeve to rotate to push the moving head toward the directional direction.

[0039] 9) The automatic cooling device for large-volume concrete condensation cycle according to 4), wherein:

[0040] The first torque disc and the second torque disc include a fixed disc, the fixed disc of the first torque disc is fixed on the free end of the first rotating shaft, and the fixed disc of the second torque disc is fixed on the free end of the second rotating shaft. The fixed disc has two accommodating chambers arranged side by side, the first ratchet is rotatably connected in one accommodating chamber, and the second ratchet is rotatably connected in the other accommodating chamber, the first ratchet and the second ratchet are coaxially connected to a core shaft connected to the first swing shaft, and a driving telescopic pump for loosening the first ratchet is respectively provided in the fixed disc, the driving telescopic pump has a driving telescopic rod facing the first ratchet or the second ratchet, the free end of the driving telescopic rod is hinged with a pawl that can be embedded in or away from the first ratchet or the second ratchet, a hinge shaft is passed through the pawl and the driving telescopic rod, and a torsion spring is sleeved on the hinge shaft.

[0041] In the above technical solution, the first torque disk supports the first ratchet and the second ratchet through its fixed disk. Similarly, the second torque disk supports the first ratchet and the second ratchet through its fixed disk. The core shaft passes through the center axis of the first ratchet and the second ratchet coaxially, and can drive the core shaft to rotate when the first ratchet or the second ratchet rotates. At the same time, the end of the core shaft is connected to the first swing shaft, and when the core shaft rotates a certain angle, it drives the first swing shaft to rotate a certain angle around the center point of the core shaft, thereby realizing the first swing shaft to swing left and right along its width direction in the moving head.

[0042] Therefore, on the contrary, the first swing shaft is located to the left and right of the first left telescopic pump and the first right telescopic pump, and the first swing shaft can swing along its width direction inside the moving head. During the swinging process of the first swing shaft, the first swing shaft can drive the core shaft to rotate, and the core shaft then drives the first ratchet and the second ratchet to rotate synchronously.

[0043] When the first left telescopic pump pushes the first swing shaft to swing to the right, the driving telescopic pump corresponding to the first ratchet is started at the same time, and the driving telescopic rod of the driving telescopic pump corresponding to the first ratchet drives the pawl to extend into the first ratchet. Due to the transmission cooperation between the first pawl and the first ratchet, the swing angle of the first swing shaft is limited, so that the first swing shaft maintains the swing angle, thereby maintaining the inclination angle of the first fan group. Similarly, when the first right telescopic pump pushes the first swing shaft to swing to the left, the driving telescopic pump corresponding to the second ratchet is started accordingly, and the principle of maintaining the inclination angle of the swing of the second swing shaft is consistent with the above.

[0044] 10) The automatic cooling device for condensation cycle of large-volume concrete according to 1), wherein:

[0045] The detection end includes a first temperature sensor and a second temperature sensor, the first temperature sensor is arranged on the side of the first rotating sleeve away from the first swing axis, and the second temperature sensor is arranged on the side of the second rotating sleeve away from the second swing axis. The recording end includes a torque sensor, and the torque sensor is mounted on the torsion spring. The first temperature sensor, the second temperature sensor, the torque sensor, the first left telescopic pump, the first right telescopic pump, the second left telescopic pump, the second right telescopic pump, and the two driving telescopic pumps are electrically connected to the microprocessor respectively;

[0046] The microprocessor is provided with a torque path model, which collects the torque angle of the torque sensor to determine the movement track of the cooling water pipe and records it in the microprocessor. After the microprocessor sequentially records the torque angle of the first swing shaft and the torque angle of the second swing shaft, it drives a left telescopic pump, a first right telescopic pump, a second left telescopic pump, a second right telescopic pump and two driving telescopic pumps in reverse order to drive the first swing shaft and the second swing shaft to swing, so as to control the moving head to return to the initial position in the reverse direction.

[0047] Compared with the prior art, the present invention also has the following technical effects:

[0048] The present invention sets the hydration heat generated by each single-area concrete as a specified direction, and uses a microprocessor to receive data information of the hydration heat area generated in the single-area concrete sent by the detection end. The microprocessor sends an instruction to the moving head with the data information as the specified direction, drives the cooling water pipe to move toward the hydration heat area generated in the unidirectional area concrete, and receives the recording end of the moving head to collect the moving track of the cooling water pipe in real time, and reversely drives the moving head to reset the moving track. In this way, the cooling water pipe can be driven to return to the initial position along the moving track, so that it can be reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The following is further described in detail through specific implementation methods:

[0055] The figure marks in the drawings of the specification include: single-zone concrete 1, cooling water pipe 2, moving head 3, bidirectional motor 4, first rotating shaft 5, first left telescopic pump 6, first rotating sleeve 7, first temperature sensor 8, first right telescopic pump 9, second rotating sleeve 10, second temperature sensor 11, rotating blade 12, second rotating shaft 13, second swinging shaft 14, second left telescopic pump 15, second right telescopic pump 16, first swinging shaft 17, upper space 18, lower space 19, fixed plate 20, first ratchet 21, driving telescopic pump 22, pawl 23, second ratchet 24.

[0056] For example, see Figure 1 As shown, the automatic cooling device for the condensation cycle of large-volume concrete in this embodiment includes a multi-regional concrete unit. The multi-regional concrete unit is configured to divide the large-volume concrete into several single-region concretes 1 by region. The hydration heat generated in each single-region concrete 1 is set to a specified direction. A movable cooling water pipe 2 is placed in the single-region concrete 1. In this embodiment, the cooling water pipe 2 is a heat-resistant steel wire hose, and the cooling water pipe 2 moves in the single-region concrete 1 guided by the specified direction.

[0057] The directional drive module located in the single-zone concrete 1 is configured to have a moving head 3 arranged at the end of the cooling water pipe 2. The moving head 3 drives the cooling water pipe 2 to move in the single-zone concrete 1 in a specified direction. The end of the moving head 3 has a detection end for determining the hydration heat area generated in the single-zone concrete 1, and the moving head 3 has a recording end for collecting the movement track of the cooling water pipe 2.

[0058] The microprocessor is configured to be electrically connected to the directional drive module in each single-area concrete 1, receive the detection end of the moving head 3 to determine the hydration heat area generated in the single-area concrete 1, control the moving head 3 of the directional drive module to drive the cooling water pipe 2 to move in the single-area concrete 1 in a specified direction based on the data information transmitted by the detection end, receive the recording end of the moving head 3 to collect the movement track of the cooling water pipe 2 in real time, and reversely drive the moving head 3 to reset the movement track.

[0059] The multi-region concrete unit of this embodiment can classify the mass concrete into several single-region concretes 1 in sequence, so that the mass concrete can be cooled in blocks, thereby evenly cooling each position of the mass concrete and improving the overall mass concrete cooling effect.

[0060] At the same time, a directional driving module is set in the single-area concrete 1. The directional driving module can drive the cooling water pipe 2 to move in the single-area concrete 1. During the movement of the cooling water pipe 2 in the single-area concrete 1, on the one hand, it drives the concrete attached to the cooling water pipe 2 to shift, thereby further realizing the stirring effect. On the other hand, the cooling water pipe 2 can cool the hydration heat area generated by the concrete on the surrounding side during the movement, thereby ensuring the cooling effect of large-volume concrete.

[0061] The moving head 3 provided in the directional area module has a moving function. The detection end at the end of the moving head 3 is used to determine the hydration heat area generated by the single-area concrete 1. After determining the position of the hydration heat area generated by the single-area concrete 1, the information is sent to the microprocessor. The microprocessor sends an instruction to the directional area module to drive the moving head 3 to move toward the hydration heat area generated by the single-area concrete 1, so that the hydration heat area generated by the single-area concrete 1 is the specified direction of movement of the moving head 3. In this way, the hydration heat area generated by the single-area concrete 1 can be cooled in a fixed and directional manner, thereby improving the cooling effect of the overall large-volume concrete.

[0062] By setting the hydration heat generated by each single-area concrete 1 as a specified direction, the microprocessor is used to receive the data information of the hydration heat area generated in the single-area concrete 1 sent by the detection end. The microprocessor sends an instruction to the moving head 3 with the data information as the specified direction, driving the cooling water pipe 2 to move toward the hydration heat area generated in the one-way area concrete, and receiving the recording end of the moving head 3 to collect the moving track of the cooling water pipe 2 in real time, and reversely drive the moving head 3 to reset the moving track. In this way, the cooling water pipe 2 can be driven back to the initial position along the moving track, so that it can be reused.

[0063] See also Figure 3As shown, in this embodiment, the moving head 3 has a hollow structure, and a partition is provided inside the moving head 3. The partition divides the internal space of the moving head 3 into an upper space 18 and a lower space 19. The upper space 18 is connected to the cooling water pipe 2 and has condensed water inside the upper space 18. The lower space 19 has a driving part for driving the moving head 3 to move.

[0064] In this embodiment, the upper space 18 of the moving head 3 is connected to the cooling water pipe 2, so that the condensed water in the cooling water pipe 2 flows into the upper space 18, so that the temperature of the moving head 3 itself is relatively low, which can protect the moving head 3 from being affected by the high temperature of the hydration heat generated by the single-area concrete 1. At the same time, since the upper space 18 is located above the lower space 19, the heat generated by the driving component in the lower space 19 during the process of driving the moving head 3 to move will also be taken away by the flowing condensed water in the upper space 18, thereby ensuring the normal operation of the driving component and extending its service life.

[0065] See also Figure 2 As shown, in this embodiment, the driving member includes a bidirectional motor 4 fixed in the lower space 19, and the two ends of the bidirectional motor 4 respectively have a first output shaft and a second output shaft extending outward, the free end of the first output shaft is rotatably connected to the first rotating shaft 5, and the end of the first rotating shaft 5 away from the first output shaft is connected to the first spiral fan, the free end of the second output shaft is rotatably connected to the second rotating shaft 13, and the end of the second rotating shaft 13 away from the second output shaft is connected to the second spiral fan.

[0066] In this embodiment, the first output shaft and the second output shaft of the bidirectional motor 4 rotate in opposite directions, so that when the first output shaft drives the first rotating shaft 5 to rotate forward, it also drives the first spiral fan to rotate forward and pushes the concrete in front of the moving head 3. At the same time, the second output shaft drives the second rotating shaft 13 to rotate in the same direction, and at the same time drives the second spiral fan to rotate in the opposite direction to generate negative pressure and push the moving head 3 forward, thereby ensuring that the moving head 3 can move in a direction within the single-area concrete 1.

[0067] Among them, the first spiral fan includes a first swing shaft 17, one end of the first swing shaft 17 is rotatably connected to the first rotating shaft 5 through a first torque disk, and the end of the first swing shaft 17 away from the first rotating shaft 5 is connected to the first fan group. A first left telescopic pump 6 and a first right telescopic pump 9 are respectively provided on both sides of the first rotating shaft 5. The first left telescopic pump 6 has a first left telescopic rod toward and pushes the first swing shaft 17 to move to the right, and the first right telescopic pump 9 has a first right telescopic rod toward and pushes the first swing shaft 17 to move to the left, so that the first swing shaft 17 swings left and right along the width direction of its moving head 3 with the first torque disk as the center point.

[0068] In this embodiment, the first swing shaft 17 is rotatably connected to the first rotating shaft 5 via the first torque disk, so that the first swing shaft 17 rotates around the first torque disk as the center point. During the rotation, the first swing shaft 17 changes the rotation angle of the first fan group, thereby realizing the movement direction of the moving head 3 driven by the first fan group; in this embodiment, the first left telescopic pump 6 and the first right telescopic pump 9 are used to push the first swing shaft 17 to rotate around the first torque disk, thereby driving the first swing shaft 17 to rotate and changing the direction of its moving head 3.

[0069] Since the first left telescopic pump 6 is based on the left and right sides of the first rotating axis 5 and is located on the left side of the moving head 3, during use, the first left telescopic rod of the first left telescopic pump 6 pushes the first swing axis 17 to the right based on the right side of the first rotating axis 5, thereby changing the first fan group to tilt toward the right and thus changing the moving direction of the moving head 3; since the first right telescopic pump 9 is based on the left and right sides of the first rotating axis 5 and is located on the right side of the moving head 3, therefore, during use, the first right telescopic rod of the first right telescopic pump 9 pushes the first swing axis 17 to the left based on the right side of the first rotating axis 5 during the telescopic process, thereby changing the first fan group to tilt toward the left and thus changing the moving direction of the moving head 3.

[0070] The first left telescopic pump 6 and the first right telescopic pump 9 are both inclined and face the first swing axis 17 respectively. The free end of the first left telescopic rod and the free end of the first right telescopic rod are respectively provided with a triangular first soft colloid, and the inclined surface of the first soft colloid is parallel to the side of the first swing axis 17.

[0071] In this embodiment, the first left telescopic pump 6 and the first right telescopic pump 9 are both arranged at an angle, so that the first left telescopic rod and the first right telescopic rod are inclined toward the first swing axis 17. At the same time, the first soft colloids on the free ends of the first left telescopic rod and the free ends of the first right telescopic rod are respectively in contact with the first swing axis 17. The inclined surface of the first soft colloid is parallel to the side surface of the first swing axis 17, so that the inclined surface of the first soft colloid pushes the first swing axis 17 to change its rotation direction.

[0072] See also Figure 2As shown, in this embodiment, the second spiral fan includes a second swing shaft 14, the two ends of the second swing shaft 14 are rotatably connected to the second rotating shaft 13 through a second torque disk, the end of the second swing shaft 14 away from the second rotating shaft 13 is connected to the second fan group, and a second left telescopic pump 15 and a second right telescopic pump 16 are respectively provided on both sides of the second rotating shaft 13. The second left telescopic pump 15 has a second left telescopic rod that moves toward and pushes the second swing shaft 14 to move to the right, and the second right telescopic pump 16 has a second right telescopic rod that moves toward and pushes the second swing shaft 14 to move to the left, so that the second swing shaft 14 swings left and right along the width direction of its moving head 3 with the second torque disk as the center point.

[0073] In this embodiment, the second swing shaft 14 is rotatably connected to the second rotating shaft 13 via the second torque disk, so that the second swing shaft 14 rotates around the second torque disk as the center point. During the rotation, the second swing shaft 14 changes the rotation angle of the second fan group, thereby realizing the movement direction of the moving head 3 driven by the second fan group; in this embodiment, the second left telescopic pump 15 and the second right telescopic pump 16 are used to push the second swing shaft 14 to rotate around the second torque disk, thereby driving the second swing shaft 14 to rotate and change the direction of its moving head 3.

[0074] Since the second left telescopic pump 15 is based on the left and right sides of the second rotating axis 13 and is located on the left side of the moving head 3, during use, the second left telescopic rod of the second left telescopic pump 15 is telescoping, and the second left telescopic rod pushes the second swing axis 14 to the right based on the right side of the second rotating axis 13, thereby changing the second fan group to tilt toward the right and thus changing the moving direction of the moving head 3; since the second right telescopic pump 16 is based on the left and right sides of the second rotating axis 13 and is located on the right side of the moving head 3, therefore, during use, the second right telescopic rod of the second right telescopic pump 16 is telescoping, and the second right telescopic rod pushes the second swing axis 14 to the left based on the right side of the second rotating axis 13, thereby changing the second fan group to tilt toward the left and thus changing the moving direction of the moving head 3.

[0075] The second left telescopic pump 15 and the second right telescopic pump 16 are both arranged at an angle and face the second swing axis 14 respectively. The free end of the second left telescopic rod and the free end of the second right telescopic rod are respectively provided with a triangular second soft colloid, and the inclined surface of the second soft colloid is parallel to the side of the second swing axis 14.

[0076] In this embodiment, the second left telescopic pump 15 and the second right telescopic pump 16 are both arranged at an angle, so that the second left telescopic rod and the second right telescopic rod are inclined toward the second swing axis 14. At the same time, the second soft colloids on the free ends of the second left telescopic rod and the free ends of the second right telescopic rod are respectively in contact with the second swing axis 14. The inclined surface of the second soft colloid is parallel to the side surface of the second swing axis 14, so that the inclined surface of the second soft colloid pushes the second swing axis 14 to change its rotation direction.

[0077] exist Figure 2 In this embodiment, the first fan group includes a first rotating sleeve 7, which is fixed to the end of the first swing shaft 17 away from the first rotating shaft 5. The second fan group includes a second rotating sleeve 10, which is fixed to the end of the second swing shaft 14 away from the second rotating shaft 13. The first rotating sleeve 7 and the second rotating sleeve 10 are evenly distributed with a plurality of rotating blades 12 along their axial direction.

[0078] In this embodiment, the first rotating sleeve 7 is used to connect the rotating blades 12 and the first swing shaft 17, so that when the first swing shaft 17 rotates with the first rotating shaft 5, it drives the several rotating blades 12 evenly distributed in the circumferential direction of the first rotating sleeve 7 to rotate to push the concrete in front of the moving head 3; the second rotating sleeve 10 is used to connect the rotating blades 12 and the second swing shaft 14, so that when the second swing shaft 14 rotates with the second rotating shaft 13, it drives the several rotating blades 12 evenly distributed in the circumferential direction of the second rotating sleeve 10 to rotate to push the moving head 3 to move in a directional direction.

[0079] Also, see Figure 4 and Figure 5 As shown, in this embodiment, the first torque disc and the second torque disc include a fixed disc 20, the fixed disc 20 of the first torque disc is fixed on the free end of the first rotating shaft 5, and the fixed disc 20 of the second torque disc is fixed on the free end of the second rotating shaft 13, and the fixed disc 20 has two accommodating chambers arranged side by side, the first ratchet 21 is rotatably connected in one accommodating chamber, and the second ratchet 24 is rotatably connected in the other accommodating chamber, the first ratchet 21 and the second ratchet 24 are coaxially connected to a core shaft connected to the first swing shaft 17, and a driving telescopic pump 22 for loosening the first ratchet 21 is respectively provided in the fixed disc 20, and the driving telescopic pump 22 has a driving telescopic rod facing the first ratchet 21 or the second ratchet 24, and the free end of the driving telescopic rod is hinged with a pawl 23 that can be embedded in or away from the first ratchet 21 or the second ratchet 24, and a hinge shaft is passed through the pawl 23 and the driving telescopic rod, and a torsion spring is sleeved on the hinge shaft.

[0080] In this embodiment, the first torque disk supports the first ratchet 21 and the second ratchet 24 through its fixed disk 20. Similarly, the second torque disk supports the first ratchet 21 and the second ratchet 24 through its fixed disk 20. The core shaft runs coaxially through the central axis of the first ratchet 21 and the second ratchet 24. When the first ratchet 21 or the second ratchet 24 rotates, the core shaft can be driven to rotate. At the same time, the end of the core shaft is connected to the first swing shaft 17. When the core shaft rotates a certain angle, it drives the first swing shaft 17 to rotate a certain angle around the center point of the core shaft, thereby realizing the first swing shaft 17 to swing left and right along its width direction in the moving head 3.

[0081] Therefore, on the contrary, the first swing shaft 17 is located to the left and right of the first left telescopic pump 6 and the first right telescopic pump 9, and the first swing shaft 17 can swing along its width direction inside the moving head 3. During the swinging process of the first swing shaft 17, the first swing shaft 17 can drive the core shaft to rotate, and the core shaft then drives the first ratchet 21 and the second ratchet 24 to rotate synchronously.

[0082] When the first left telescopic pump 6 pushes the first swing shaft 17 to swing to the right, the driving telescopic pump 22 corresponding to the first ratchet 21 is started at the same time, and the driving telescopic rod of the driving telescopic pump 22 corresponding to the first ratchet 21 drives the pawl 23 to extend into the first ratchet 21. Due to the transmission cooperation between the first pawl 23 and the first ratchet 21, the swing angle of the first swing shaft 17 is limited, so that the first swing shaft 17 maintains the swing angle, thereby maintaining the tilt angle of the first fan group. Similarly, when the first right telescopic pump 9 pushes the first swing shaft 17 to swing to the left, the driving telescopic pump 22 corresponding to the second ratchet 24 is started, and the principle of maintaining the tilt angle of the swing of the second swing shaft 14 is consistent with the above.

[0083] At the same time, in this embodiment, the detection end includes a first temperature sensor 8 and a second temperature sensor 11. The first temperature sensor 8 is arranged on the side of the first rotating sleeve 7 away from the first swing axis 17, and the second temperature sensor 11 is arranged on the side of the second rotating sleeve 10 away from the second swing axis 14. The recording end includes a torque sensor, which is installed on the torsion spring. The first temperature sensor 8, the second temperature sensor 11, the torque sensor, the first left telescopic pump 6, the first right telescopic pump 9, the second left telescopic pump 15, the second right telescopic pump 16 and the two driving telescopic pumps 22 are electrically connected to the microprocessor respectively.

[0084] A torque path model is provided in the microprocessor. The torque path model collects the torque angle of the torque sensor to determine the moving track of the cooling water pipe 2 and records it in the microprocessor. After the microprocessor sequentially records the torque angle of the first swing shaft 17 and the torque angle of the second swing shaft 14, it drives a left telescopic pump, a first right telescopic pump 9, a second left telescopic pump 15, a second right telescopic pump 16 and two driving telescopic pumps 22 in reverse order to drive the first swing shaft 17 and the second swing shaft 14 to swing to control the moving head 3 to return to the initial position in reverse.

[0085] In this embodiment, the hydration heat generated by each single-region concrete 1 is set as a specified direction. The microprocessor is used to receive data information of the hydration heat area generated in the single-region concrete 1 sent by the detection end. The microprocessor sends an instruction to the moving head 3 with the data information as the specified direction, drives the cooling water pipe 2 to move toward the hydration heat area generated in the unidirectional regional concrete, and receives the recording end of the moving head 3 to collect the moving track of the cooling water pipe 2 in real time. The moving head 3 is driven in reverse to reset the moving track. In this way, the cooling water pipe 2 can be driven back to the initial position along the moving track, so that it can be reused.
