Description

Technical Field

[0001] The present invention relates to the field of prefabricated block maintenance, and more particularly to invert prefabricated block maintenance equipment. Background Art

[0002] In tunnel construction, the quality of the precast blocks of the inverts plays a key role in the stability and durability of the tunnel structure. At present, the maintenance of most precast blocks of the inverts depends on the independent operation of a single maintenance device. This single-device maintenance method has many disadvantages that are difficult to overcome. On the one hand, due to the independent operation of the equipment and the lack of an effective coordination mechanism between the equipment, it is difficult to achieve unified and precise control of the maintenance environment of multiple precast blocks of the inverts, resulting in uneven temperature and humidity control. This makes the strength development of the precast blocks inconsistent during the maintenance process, seriously affecting the uniformity of product quality. On the other hand, the heat dissipation method of a single device is often limited to its own simple heat dissipation structure, and it is impossible to carry out systematic heat exchange and balanced adjustment, which greatly affects the maintenance efficiency. In addition, each single maintenance device is equipped with an independent water supply and discharge system, which cannot achieve centralized recovery and recycling of water resources, resulting in serious waste of water resources, thereby increasing maintenance costs.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0022] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] like Figure 1 and Figure 2 As shown, the present invention provides an inverted arch prefabricated block curing device, the box of the curing device is composed of a middle module 1 and six outer modules 2, and the middle module 1 and the six outer modules 2 are all hexagonal. The six side walls of the middle module 1 overlap with one of the side walls of the six outer modules 2 respectively, forming a tight connection structure. This layout method helps to achieve the coordinated work of heat transfer and air circulation between the outer modules 2.

[0024] Multiple temperature sensors and humidity sensors are arranged at intervals on the inner wall of each outer module 2 to monitor the temperature and humidity inside the outer module 2 in real time and accurately. At least one nozzle for spraying curing agent and at least one nozzle for spraying steam are arranged on the top of each outer module 2. When the temperature and humidity sensor in the outer module 2 detects that the temperature and humidity data deviate from the preset range, the nozzle will increase or decrease the spraying amount according to the temperature and humidity sensor data in the outer module 2 to adjust the temperature and humidity environment in the outer module 2 to meet the maintenance requirements of the invert prefabricated block.

[0025] At least one first heat pipe 3 and at least one second heat pipe 4 are arranged at intervals on the common wall between two adjacent outer modules 2. The heat absorption section of each first heat pipe 3 is located in one outer module 2 (outer module A) of the two adjacent outer modules 2 (outer module A and outer module B), and the heat release section is located in the other outer module 2 (outer module B) of the two adjacent outer modules 2; the heat absorption section and heat release section of each second heat pipe 4 are opposite to the first heat pipe 3, that is, the heat absorption section of each second heat pipe 4 is located in the other outer module 2 (outer module B) of the two adjacent outer modules 2, and the heat release section is located in one outer module 2 (outer module A) of the two adjacent outer modules 2. Through this heat pipe layout, heat transfer and balance between adjacent outer modules 2 are achieved, the temperature difference between the outer modules 2 is effectively reduced, and a stable temperature environment is created for the invert prefabricated block.

[0026] Each outer module 2 is provided with an air inlet and an air outlet 6, and the middle module 1 is provided with a main air duct 5, which is connected to the air inlets of the six outer modules 2 through the first branch pipes. Figure 2 In the figure, arrows indicate the direction of wind entering and exiting the outer module 2. This ventilation system design ensures that air can circulate evenly between the outer modules 2, promoting heat exchange and uniform distribution of temperature and humidity.

[0027] Each of the six outer modules 2 is provided with a support platform 7 for supporting the inverted arch prefabricated block, and each first branch pipe is provided with an air volume adjusting member (valve). The air volume adjusting member can finely control the air volume of each first branch pipe. When a certain outer module 2 requires special air volume adjustment due to changes in internal temperature and humidity, it can be adjusted independently through the corresponding air volume regulating valve without being affected by other outer modules 2. For example, if the temperature in a certain outer module 2 rises abnormally, increasing the air volume of the outer module 2 only by increasing the fan speed of the main air duct 5 may cause unnecessary changes in the air volume of other outer modules 2. With the air volume adjusting member, the air intake of this outer module 2 can be accurately increased to achieve efficient cooling. And during the operation of the equipment, different maintenance stages have different requirements for the temperature and humidity of each outer module 2. For example, in the initial stage of maintenance, each outer module 2 has high requirements for humidity and the differences are not large, so it may be necessary to uniformly adjust the fan speed of the main air duct 5; but in the later stage, each outer module 2 has different requirements for temperature and humidity due to the differences in the status of the prefabricated blocks. At this time, the air volume can be flexibly adjusted according to the specific conditions of each outer module 2 through the air volume adjustment member to optimize the maintenance environment. And when the ventilation duct or equipment of a certain outer module 2 fails, the air volume of the outer module 2 can be closed or reduced through the air volume adjustment member to prevent the expansion of the fault and ensure the normal operation of other outer modules 2. For example, if the nozzle of a certain outer module 2 is blocked, resulting in abnormal humidity in the outer module 2, the air volume can be reduced through the air volume adjustment member to reduce the impact of uneven water evaporation on other outer modules 2, so as to focus on repairing the faulty outer module 2.

[0028] The inverted arch prefabricated block maintenance equipment provided in this solution, when the equipment is running, multiple temperature sensors and humidity sensors arranged at intervals on the inner wall of each outer module 2 will continuously and in real time monitor the temperature and humidity data inside the outer module 2. These sensors will quickly and accurately transmit the acquired temperature and humidity information to the control system, providing data basis for subsequent adjustment operations.

[0029] When the temperature sensor detects that the temperature in a certain outer module 2, such as outer module A, is too high, the heat pipe system starts to work. The first heat pipe 3 transfers the heat of the outer module A to the adjacent outer module B or outer module C to achieve a balanced distribution of heat. At the same time, the ventilation system works closely together, and the control system adjusts the fan speed of the main air duct 5 and the air volume distribution of each first branch pipe according to the temperature data of each outer module 2, so that the air inlet of the outer module A in the high-temperature area obtains a larger air volume. The strong airflow quickly takes away the heat in the outer module A, accelerates the heat exchange of the air, and thus achieves rapid cooling.

[0030] If the temperature sensor detects that the temperature of a certain outer module 2, such as outer module B, is too low, the control system will reduce the speed of the fan in the main air duct 5 to reduce the overall ventilation volume. At the same time, the air volume of each first branch duct is fine-tuned to reduce the air intake of the outer module B to maintain a relatively stable microenvironment in the outer module B and avoid further heat loss due to excessive ventilation.

[0031] When the humidity sensor detects that the humidity is lower than the preset range, the nozzles installed on the top of each outer module 2 start to work, increasing the amount of curing agent or steam sprayed to increase the humidity in the outer module 2. At the same time, the ventilation system is coordinated and adjusted, and the fan of the main air duct 5 appropriately reduces the wind speed to reduce the promotion of air flow on water evaporation, so that the humidity in the curing space can be maintained at an appropriate level.

[0032] If the humidity is higher than the preset range, the nozzle reduces the spraying amount. The ventilation system increases its working intensity, and the fan of the main air duct 5 greatly increases the rotation speed, increases the ventilation volume, speeds up the air circulation speed, and accelerates the evaporation of water. In addition, the control system specifically adjusts the wind speed of each first branch pipe according to the uneven distribution of humidity in each outer module 2, so that the area with higher humidity obtains a higher wind speed, prompting the excess water to be quickly discharged from the outer module 2, so as to achieve the purpose of quickly reducing the humidity.

[0033] The support platform 7 in the six outer modules 2 provides a stable placement foundation for the inverted arch precast blocks. During the entire maintenance process, the operator needs to regularly check the placement status of the precast blocks on the support platform 7 to ensure that it is stable and meets the maintenance requirements.

[0034] In another solution, multiple third heat pipes 8 are arranged at intervals on the six walls of the middle module 1, and the heat absorption section of each third heat pipe 8 is located in the six corresponding outer modules 2, and the heat release section is located in the middle module 1, further enhancing the temperature balance effect of the entire box.

[0035] The heat of the six outer modules 2 is transferred to the middle module 1 for dissipation. This structure allows the heat to be transferred from the outer modules 2 with higher temperatures to the middle module 1, avoiding local overheating of the outer modules 2 and making the temperature distribution of the entire box more uniform.

[0036] In another solution, temperature sensors are installed around the heat release section of each third heat pipe 8 to monitor the temperature change of the heat release section of each third heat pipe 8 in real time. Heat release fins with nested telescopic structures are provided at the heat release section of each third heat pipe 8, and each heat release fin is composed of a multi-layer plate body. The plates located in the innermost layer of each heat release fin are fixedly connected to the heat release section of the corresponding third heat pipe 8 to ensure that heat can be quickly transferred to the heat release fins. The plates located in the outer layers are nested in sequence, and the plates located in the outermost layer can move along the length direction of the heat release section of the third heat pipe 8 under the drive of the driving mechanism, and the heat dissipation area is adjusted by adjusting the extension degree of the heat release fins.

[0037] When the maintenance equipment is running, the heat absorption section of each third heat pipe 8 absorbs the heat of the corresponding outer module 2 and conducts the heat to the heat release section of the third heat pipe 8. The temperature sensors installed around the heat release section of each third heat pipe 8 monitor the temperature changes therein in real time and transmit the data to the control system.

[0038] The heat dissipation fins are composed of multiple layers of nested plates, and the plates located in the innermost layer are fixedly connected to the heat release section of the third heat pipe 8 to ensure rapid heat transfer. As the temperature of the heat release section of the third heat pipe 8 rises, the driving mechanism causes the plates located in the outermost layer to move along the length direction of the heat release section of the third heat pipe 8 to expand the heat dissipation fins, thereby increasing the heat dissipation area and enhancing the heat dissipation effect. When the temperature drops to a suitable range, the driving mechanism causes the plates located in the outermost layer to move in the opposite direction along the length direction of the heat release section of the third heat pipe 8 to shrink the heat dissipation fins and reduce the heat dissipation area, thereby dynamically adjusting the heat dissipation, maintaining the temperature stability of the equipment, ensuring the temperature balance and stability of the curing environment of the invert prefabricated blocks, and improving the quality and efficiency of curing.

[0039] In another embodiment, the driving mechanism includes a motor, a screw and a nut seat. Both ends of each screw are rotatably connected to the mounting bracket of the heat release section of the corresponding third heat pipe 8, one end of each screw is connected to the output shaft of the corresponding motor, and each screw is sleeved with a nut seat matching the thread. Each nut seat is connected to the plate body located at the outermost layer of the corresponding heat dissipation fin through a connecting rod. When the motor is started, it drives the screw to rotate, so that the nut seat moves along the axial direction of the screw, thereby realizing the extension and contraction of the heat dissipation fin.

[0040] In the initial state, the heat sink fins may be in a contracted or partially extended state. When the temperature sensor detects that the temperature of the heat release section of the third heat pipe 8 has risen and needs to enhance heat dissipation, the control system starts the drive mechanism. The motor in the drive mechanism drives the screw to rotate. Since the nut seat matches the screw thread and is connected to the outermost plate body of the heat sink fins through a connecting rod, the nut seat will move along the axial direction of the screw, thereby pushing the heat sink fins located in the outermost plate body to extend along the length direction of the heat release section of the third heat pipe 8. As the heat sink fins located in the outer layer of the plate body are unfolded one by one, the overall heat dissipation area of ​​the heat sink fins increases, the heat exchange efficiency is improved, and the heat is accelerated to the surrounding environment. When the temperature drops to a suitable range, the control system drives the motor to reverse, shrink the heat sink fins, reduce unnecessary heat dissipation area, and avoid excessive heat loss, so as to flexibly adjust the heat dissipation effect under different temperature conditions, maintain the stability of the equipment temperature, ensure the temperature balance and stability of the curing environment of the invert precast block, and effectively improve the quality and efficiency of curing.

[0041] In another scheme, a plurality of second branch pipes are provided at the air outlet end of the main air duct 5, and the number of each second branch pipe is equal to the number of the third heat pipes 8, and they correspond one to one, and their air outlet ends are respectively oriented to the heat release section of the corresponding third heat pipe 8. An airflow guiding device is provided at the air outlet end of each second branch pipe, and each airflow guiding device includes a guide plate, an angle adjustment motor and an angle sensor. The guide plate is rotatably connected to the inner wall of the corresponding second branch pipe, and the output shaft of the angle adjustment motor is connected to the guide plate to drive the guide plate to rotate. The angle sensor is arranged on the output shaft of the angle adjustment motor to monitor the angle of the guide plate in real time. Each airflow guiding device is respectively matched with the extension direction of the heat sink fins. When the heat sink fins are extended, the airflow guiding device adjusts the angle toward the extension direction of the heat sink fins, guides the airflow to the gap between the heat sink fins, and enhances the heat dissipation effect.

[0042] High-precision temperature sensors are installed around the heat release sections of each third heat pipe 8. The temperature sensors continuously monitor the temperature of the heat release sections of the third heat pipes 8 in real time and quickly transmit the collected temperature data to the control system of the equipment.

[0043] When the heat release section of the third heat pipe 8 needs to dissipate heat during the operation of the maintenance equipment, the wind of the main air duct 5 flows to the corresponding heat release section of the third heat pipe 8 through multiple second branch pipes. At this time, the airflow guide device located at the air outlet end of the second branch pipe begins to play a role.

[0044] The angle sensor monitors the angle of the guide plate in real time and feeds the data back to the control system. When the heat sink fins extend due to the increase in temperature, the control system starts the angle adjustment motor based on the extension direction of the heat sink fins. The angle adjustment motor drives the guide plate to rotate and adjust its angle in the extension direction of the heat sink fins, thereby accurately guiding the airflow to the gap between the heat sink fins.

[0045] In this way, the wind blown out from the second branch pipe can more effectively pass through the space between the heat sink fins, increase the contact area and contact efficiency between the air and the heat sink fins, accelerate the heat transfer from the heat sink fins to the flowing air, and then enhance the heat dissipation effect of the entire heat dissipation system, ensure that the third heat pipe 8 can efficiently dissipate the heat absorbed by the outer module 2, maintain the temperature balance inside the maintenance equipment, and provide a stable maintenance environment temperature for the invert prefabricated block. When the temperature sensor detects that the temperature of the heat release section of the third heat pipe 8 is within the preset appropriate range, that is, the heat distribution inside the equipment is relatively balanced and no additional heat dissipation is required, the control system will not start the relevant heat dissipation enhancement operation.

[0046] At this time, the main air duct 5 may still maintain a certain basic ventilation volume to maintain air circulation in the device and prevent local temperature accumulation, but will not provide additional airflow to the second branch duct. The angle adjustment motor is in an inoperative state, and the guide plate is maintained at a basic angle position to ensure that it will not interfere with the normal airflow inside the device. At the same time, the heat dissipation fins are also in a retracted or relatively compact state to reduce their occupation of the internal space of the device and avoid unnecessary heat dissipation.

[0047] The various components of the maintenance equipment will remain in a low-power, low-activity state, and only perform some basic monitoring work, such as the temperature sensor continues to monitor the temperature so that it can respond in time when the temperature of the heat release section of the third heat pipe 8 changes and needs to be dissipated.

[0048] This mechanism of flexibly adjusting the heat dissipation operation according to the temperature monitoring results not only ensures that the heat dissipation effect can be effectively enhanced when heat dissipation is needed, but also avoids unnecessary energy waste when heat dissipation is not needed, thereby realizing the efficient and stable operation of the maintenance equipment under different temperature conditions and providing a good maintenance environment for the invert precast blocks.

[0049] In another solution, each second branch pipe is equipped with a flow regulating valve at a position close to the heat release section of the corresponding third heat pipe 8. When each heat dissipating fin is extended, the corresponding flow regulating valve increases the air volume to accelerate heat dissipation; when each heat dissipating fin is partially contracted, the corresponding flow regulating valve reduces the air volume; when each heat dissipating fin is completely contracted, the corresponding flow regulating valve reduces the air volume to zero to avoid energy waste.

[0050] When the heat dissipation fins are stretched due to the increase in the temperature of the heat dissipation section of the third heat pipe 8, it means that the heat dissipation capacity needs to be enhanced. At this time, the flow control valve plays a role.

[0051] The working principle of the flow control valve is to control the air volume in the duct by adjusting the opening of the valve. When the heat sink fins are extended, the control system receives feedback information from the extension state of the heat sink fins, such as an electrical signal triggered when the heat sink fins are extended.

[0052] Based on this feedback, the control system will send instructions to the corresponding flow regulating valve to increase the valve opening. After the valve opening increases, more wind can flow to the heat release section of the third heat pipe 8 through the second branch pipe. Under the guidance of the airflow guide device, these winds pass through the gaps between the extended heat dissipation fins more effectively, enhance the heat exchange between the air and the heat dissipation fins, and accelerate the transfer of heat from the heat dissipation fins to the flowing air, thereby achieving the purpose of accelerating heat dissipation.

[0053] When the heat sink fins shrink due to the temperature drop, it indicates that the current heat dissipation demand has decreased. At this time, the shrinkage status information of the heat sink fins will be fed back to the control system.

[0054] Based on this information, the control system sends an adjustment instruction to the corresponding flow control valve to reduce the valve opening. As the flow control valve opening decreases, the air volume passing through the second branch pipe decreases accordingly. In this way, the amount of cold air entering the heat sink fin area is reduced, so that the intensity of the heat dissipation process matches the heat dissipation capacity of the heat sink fins, avoiding energy waste caused by excessive heat dissipation, while maintaining a relatively stable internal temperature of the equipment, achieving the effect of finely adjusting heat dissipation.

[0055] When the heat sink fins are fully retracted, it indicates that the heat inside the current device has been effectively controlled and no additional heat dissipation is required.

[0056] After the control system receives the signal that the heat sink fins are fully retracted, it will send a command to the corresponding flow control valve to completely close the valve. At this time, the flow control valve reduces the air volume to zero, preventing air from continuing to flow into the area, avoiding energy waste caused by continuing to supply air to areas that no longer need heat dissipation. In this way, the energy of the equipment can be more focused on other necessary operations, while maintaining a stable temperature inside the equipment, preventing unnecessary heat loss or the introduction of additional temperature interference factors, and ensuring the efficient operation of the maintenance equipment and the stability of the maintenance environment.

[0057] Through this mechanism of dynamically adjusting the flow control valve according to the extension and contraction state of the heat dissipation fins, flexible and precise control of the equipment heat dissipation system is achieved. It can not only quickly enhance heat dissipation when needed, but also reasonably adjust the air volume at different heat dissipation demand stages to avoid energy waste, ensure that the maintenance equipment can operate in the best state under different working conditions, provide a stable maintenance environment for the invert prefabricated blocks, and take into account the energy efficiency and performance of the equipment.

[0058] In another solution, a sub-drainage trough is provided at the bottom of each of the six outer modules 2, and the six sub-drainage troughs are connected end to end to form a hexagonal main drainage trough 9. The main drainage trough 9 is connected to a drainage pipe 10, and the drainage end of the drainage pipe 10 is located outside the box. A liquid level sensor and an electromagnetic drainage valve are provided in the drainage pipe 10. The liquid level sensor monitors the water level change in real time. When the liquid level reaches a preset threshold, the electromagnetic drainage valve automatically opens to discharge sewage.

[0059] In another embodiment, the drainage end of the drainage pipe 10 is connected to the water inlet of the water purifier. The water purifier is provided with three layers of filter elements. The first layer of filter element is a coarse filter screen, the middle layer of filter element is an ultrafiltration membrane, and the last layer of filter element is a reverse osmosis membrane.

[0060] After the water discharged from the drain pipe 10 enters the water purifier, it first passes through the coarse filter. The coarse filter uses its larger mesh to intercept large particles of impurities such as silt, rust, and suspended matter through physical screening to prevent them from entering the subsequent filter layer, thus playing a preliminary purification and protection role.

[0061] The water filtered by the coarse filter enters the ultrafiltration membrane. The pore size of the ultrafiltration membrane is 0.01-0.1 microns. Through the pressure difference on both sides of the membrane, small molecules such as water molecules and some ions can pass through the membrane, while large molecules (bacteria, some viruses, colloids, etc.) are intercepted on the membrane surface or in the membrane pores to further purify the water quality.

[0062] The water passing through the ultrafiltration membrane enters the reverse osmosis membrane. The pore size of the reverse osmosis membrane is extremely small (about 0.1-1 nanometers). Under a certain pressure, according to the principle of osmotic pressure, only water molecules are allowed to pass through, while almost all ions, organic matter, microorganisms, etc. are intercepted. It can remove most soluble solids and heavy metal ions and provide high-purity water.

[0063] By filtering through coarse filter, ultrafiltration membrane and reverse osmosis membrane in sequence, the filtering effect is improved and the service life of the water purifier is extended.

[0064] In another solution, each steam spraying nozzle is connected to the steam generator located in the middle module 1, and the purified water is re-transported to the steam generator through a circulation pump, thereby realizing the recycling of water resources, improving the utilization rate of water resources, and reducing maintenance costs.

[0065] In another solution, the air inlets and outlets 6 on the six outer modules 2 are respectively arranged on two opposite side walls, and the air inlets on the six outer modules 2 are respectively arranged on the six side walls of the middle module 1. A smooth air circulation path is constructed so that the air can flow evenly and quickly in each outer module 2 to avoid poor airflow and stagnation. It is conducive to the rapid diffusion of the curing agent and steam sprayed from the nozzle, and the temperature and humidity are comprehensively and accurately adjusted to maintain a stable curing environment. The collaborative heat pipe system accelerates heat transfer and exchange, balances the temperature of each outer module 2, and improves the consistency of curing quality. Ensure that the air pressure of each outer module 2 is balanced, reduce equipment operation fluctuations, and enhance equipment stability and reliability.
