Description

Technical Field

[0001] This utility model relates to the field of river construction technology, and in particular to a winter construction heating shed device. Background Technology

[0002] During river construction, in order to form a stable structure and reduce water leakage, concrete is often poured to form a solid protective structure and a concrete impermeable layer when constructing riverbanks, slopes, and the bottom of the river. This effectively prevents groundwater loss, maintains stable river water volume, and ensures ecological and irrigation water needs.

[0003] During river channel construction in winter, the ambient temperature is low, with temperatures in many areas below 0°C (i.e., sub-zero temperatures). Especially in high-altitude and cold regions, the construction period is short, with winter lasting up to 6 months and winter temperatures below -30°C. The construction cycle of the pier structure is long, and construction often spans multiple years.

[0004] During winter river construction, the moisture in materials such as soil, concrete, and mortar used is prone to freezing, and building materials are easily brittle under environmental influences, which brings many difficulties to construction and greatly affects the construction progress.

[0026] Example 1

[0027] like Figures 1-3 As shown:

[0028] A winter greenhouse heating device includes a main frame 1, the main frame 1 is covered with an insulating tarpaulin 21, the two ends of the main frame 1 are covered with a closed tarpaulin 22 with inlet and outlet 24, the closed tarpaulin 22 is equipped with a ventilation pipe 23, and also includes a temperature regulation mechanism for heating the inside of the greenhouse.

[0029] The main frame 1 consists of two end arch frames 11 and multiple intermediate arch frames 12. The main frame 1 is welded from hot-dip galvanized square steel pipes, and adjacent arch frames are supported and connected by crossbeams 13.

[0030] The arch frame consists of a top arched section and two vertical sections 14 connected together. The bottom of the vertical section 14 is welded with a 10mm thick steel plate base. The arched section adopts a circular arc design, and the cross-sectional dimensions are optimized through finite element analysis to ensure wind load resistance ≥0.5kN / m2.

[0031] The bottom of the arch frame is equipped with self-locking casters 15. The self-locking casters 15 facilitate the movement of the greenhouse in the river construction area. The self-locking mechanism on the self-locking casters 15 can fix the position of the greenhouse and prevent the greenhouse from sliding during construction. The self-locking casters 15 are conventional components, and their internal structure will not be described in detail here.

[0032] The thermal insulation tarpaulin 21 covers the outside of the main frame 1. The thermal insulation tarpaulin 21 adopts a multi-layer structure, including an inner layer of thermal insulation cotton, a middle waterproof and breathable membrane layer, and an outer layer of wear-resistant and windproof fabric. The multi-layer structure effectively improves the thermal insulation, waterproof and windproof performance. The edges of the thermal insulation tarpaulin 21 are connected to the main frame 1 by zippers or Velcro, which facilitates disassembly and replacement.

[0033] The enclosed tarpaulin 22 is made of double-sided coated canvas. The entrance and exit 24 are 1.5 meters wide and 2 meters high. The entrance and exit 24 are equipped with a magnetic sealing curtain with a built-in permanent magnet strip. When closed, the airtightness is ≥0.5m3 / (m·h).

[0034] A retractable mechanism for taking up and taking down the thermal insulation tarpaulin 21 is slidably installed on the side of the main frame 1. The retractable mechanism moves up and down along the height of the main frame 1.

[0035] The rolling mechanism includes a roller shutter 3 mounted opposite each other on the outer surfaces of the two end arches 11. The roller shutter 3 is a conventional component, and its internal structure will not be described in detail here. A synchronously driven roller 31 is installed between the two roller shutters 3. A rack 33 is installed on the end arches 11 along the height of the vertical section 14 of the end arches 11. A drive gear 32 is installed on the roller shutter 3 to drive the rotation and mesh with the rack 33.

[0036] The output shaft of the internal drive motor of the roller shutter machine 3 is connected to the drive gear 32. The output shaft is connected to the roller 31 through the synchronous belt transmission mechanism. The bottom edge of the heat-insulating tarpaulin 21 is installed on the roller 31 by stainless steel clips and rivets. The heat-insulating tarpaulin 21 is wound on the roller 31. The diameter of the roller 31 is designed according to the width of the heat-insulating tarpaulin 21 and the number of winding layers (for example, when the tarpaulin width is 10m and 5 layers are wound, the diameter of the roller 31 is ≥30cm). The surface of the roller 31 can be processed with anti-slip texture to prevent the tarpaulin from slipping.

[0037] In this embodiment, the roller shutter machine 3 uses a dual-output shaft geared motor (power 2.2kW, reduction ratio 1:30). One end of the output shaft is equipped with a drive gear 32 with a module of 4 and 20 teeth, and the other end is connected to the drum 31 through a synchronous belt transmission mechanism (transmission ratio 1:2). The rack 33 is made of 45# steel with a module of 4. The motor has a built-in electromagnetic brake that automatically locks the output shaft when the power is off.

[0038] An L-shaped sliding bracket 4 is provided between the roller shutter machine 3 and the main frame 1. The roller shutter machine 3 is fixedly installed on the sliding bracket 4. A T-shaped guide groove 41 is provided on the side wall of the vertical section 14 of the end arch frame 11. A guide block that cooperates with the guide groove 41 is provided on the sliding bracket 4.

[0039] In this embodiment, the L-shaped sliding bracket 4 is guided to the two side walls on the vertical section 14 of the end arch 11, which further improves the moving stability of the roller shutter machine 3.

[0040] In this embodiment, a control box is installed on the main frame 1 inside the greenhouse, and the control box is equipped with a rewind button and a lowering button.

[0041] The temperature control mechanism includes an industrial hot air blower 5. The air outlet of the industrial hot air blower 5 is connected to the interior of the greenhouse through an air outlet pipe 51. Inside the greenhouse, there is an air distribution pipe with evenly distributed warm air vents, which is connected to the air outlet pipe 51. The power supply and other equipment required for the industrial hot air blower to function are standard features in this field and will not be described in detail here.

[0042] A temperature sensor is installed on the main frame 1, and a valve or electric louver electrically connected to the temperature sensor is installed inside the ventilation duct 23. The ventilation volume of the ventilation duct 23 is ≥2000m3 / h and is used for air exchange.

[0043] The temperature regulation mechanism can also use a graphene electric heating film connected to an external DC24V safe power supply. The graphene electric heating film is installed on the main frame 1 near the concrete pouring location via aluminum foil tape. A temperature sensor electrically connected to the power supply equipment is installed on the main frame 1. The surface of the film is covered with a flame-retardant non-woven protective layer.

[0044] The control box integrates a PLC controller, a temperature sensor interface, a motor control module, and a power switch. The front panel features a take-up button, a lower button, a temperature setting knob (adjustable range 5-25℃), and a fault indicator light.

[0045] When the temperature sensor detects that the temperature inside the shed is lower than the set value, the PLC controller starts the heating equipment according to the preset priority (such as prioritizing the graphene electric heating film and linking the industrial hot air blower 5 when the load is insufficient). The industrial hot air blower 5 delivers 60-80℃ hot air into the shed through the air outlet duct 51, and the graphene electric heating film heats the surrounding air through radiative heat transfer. The two methods work together to make the temperature inside the shed rise evenly.

[0046] When the temperature exceeds the set upper limit or the humidity inside the shed is greater than 85%, the valve or electric louver of the ventilation pipe 23 will automatically open to expel the hot and humid air, while fresh air from outside will be replenished through the inlet and outlet 24 to form an air circulation.

[0047] Working principle of this device:

[0048] When it is necessary to open the side ventilation of the greenhouse or to hoist construction materials, the operator presses the roll-up button on the control box. The drive gear 32 of the double roll-up machine 3 begins to mesh with the rack 33. Through the gear and rack 33 transmission, the roll-up machine 3 climbs up along the guide groove 41. At the same time, the synchronous belt drives the drum 31 to rotate, so that the heat-insulating tarpaulin 21 is evenly rolled onto the drum 31.

[0049] Synchronization control: Since the two roller shutter machines 3 are rigidly connected by the roller drum 31 and the installation accuracy of the rack 33 is ≤1mm / m, the rolling speed on both sides can be kept consistent, avoiding the tarpaulin from tilting.

[0050] Limit protection: A limit switch is installed at the top of the end arch frame 11. When the roller shutter 3 rises to the limit position, the power is automatically cut off to prevent it from hitting the top; a buffer rubber pad is installed at the bottom to avoid impact when lowering.

[0051] Two hours before concrete pouring, the temperature control mechanism is activated to raise the temperature inside the shed to 10-15℃, ensuring the concrete's placement temperature is ≥5℃. During construction, temperature sensors monitor the shed's temperature and humidity in real time. When the temperature drops below 8℃, the heating equipment's power is automatically increased; when the humidity exceeds 80%, ventilation duct 23 is opened for exhaust. After each day's construction, the sealed doors at the entrance and exit 24 are closed to maintain the shed's temperature at ≥5℃, ensuring the concrete's strength development.

[0052] When the construction area is changed, the insulation tarpaulin 21 is first rolled up with the roller 31 along with the roller shutter 3 to reduce movement resistance; then the casters are unlocked and the greenhouse is moved to the new position by the traction equipment, the base is fixed again and the tarpaulin is unfolded.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
