Description

Technical Field

[0001] The present application relates to the technical field of roof cooling, and in particular to a novel roof cooling air cooling device. Background Art

[0002] In the industrial steel rolling production workshop, the production process will generate a lot of hot air. Hot air is lighter than cold air, so the hot air will float upwards and gather under the roof. In the high temperature of summer, the temperature on the roof can reach 80℃, which can easily cause the equipment installed on the roof, such as monitoring and scanners, to get stuck or even fail, resulting in system shutdown, which seriously affects the progress of on-site work, so it needs to be improved. Utility Model Content

[0003] In order to effectively cool down the roof of a factory building and ensure the normal operation of the rooftop equipment, the present application provides a new type of rooftop cooling air cooling device.

[0004] The present application provides a novel rooftop cooling air cooling device that adopts the following technical solution:

[0005] A novel rooftop cooling air-cooling device comprises a centrifugal fan arranged outside a factory building, the centrifugal fan is connected to a ventilation duct, the other end of the ventilation duct extends into the factory building, the air outlet of the ventilation duct is arranged toward the direction of the rooftop equipment, a control cabinet is arranged in the factory building, the centrifugal fan is electrically connected to the control cabinet, a temperature sensor for detecting the temperature at the roof is arranged on the rooftop equipment, the temperature sensor is communicatively connected to the control cabinet, and the control cabinet controls the opening and closing of the centrifugal fan based on the detection value of the temperature sensor.

[0006] By adopting the above technical solution, the temperature sensor detects the temperature of the rooftop equipment in real time. When the detection value exceeds the preset value, the centrifugal fan will be started to draw outdoor cold air through the ventilation duct, thereby air-cooling the rooftop equipment to ensure that the rooftop equipment can be at a normal temperature, thereby ensuring the effective progress of the process; when the detection value does not reach the preset value, the air cooling device will not start, thereby effectively saving energy and having high economic benefits.

[0007] Optionally, a plurality of positioning rods are vertically arranged on the bottom wall of the roof, and the plurality of positioning rods are distributed along the length direction of the ventilation pipe. Positioning rings are arranged at the bottom ends of the positioning rods, and the ventilation pipe passes through the positioning rings in sequence.

[0008] By adopting the above technical solution, the positioning rod is provided to improve the stability of the ventilation pipe installation to prevent the ventilation pipe from tilting, bending, etc. under the action of gravity, thereby ensuring that the roof can be cooled stably.

[0009] Optionally, a flange is provided at one end of the positioning rod close to the roof, and a plurality of locking members for fixing the positioning rod are provided on the flange.

[0010] By adopting the above technical solution and arranging a flange, the positioning rod and the roof are detachably connected, thereby facilitating the disassembly of the positioning rod to replace the aged ventilation pipe, thereby achieving high convenience.

[0011] Optionally, one end of the ventilation pipe inserted into the factory building includes a fixed part and a telescopic part, the telescopic part is slidably connected to the fixed part, the roof is provided with an adjustment track, the adjustment track is slidably connected to a mounting plate, one of the positioning rods is installed on the mounting plate, and the adjustment track drives the telescopic part to slide relative to the fixed part.

When there are many devices installed on the roof, different devices can be cooled, which has high flexibility and practicality.

[0013] Optionally, the peripheral wall of the fixing portion abuts against the inner wall of the positioning ring, and a plurality of balls are provided on the inner wall of the positioning ring sleeved on the outside of the telescopic portion, and the balls abut against the outer wall of the telescopic portion.

[0014] By adopting the above technical solution, the ball bearings can effectively reduce the friction force when the telescopic part slides, reduce wear, and thus improve the smoothness of the sliding of the telescopic part relative to the fixed part.

[0015] Optionally, two sleeve rings are provided on the peripheral wall of one end of the telescopic part away from the fixed part, the outer walls of the sleeve rings abut against the inner wall of the positioning ring, and anti-slip sheets are provided on the end walls of the two sleeve rings away from each other, and the positioning ring is located between the anti-slip sheets on both sides.

[0016] By adopting the above technical solution, the anti-slip sheets on both sides play a limiting role on the positioning ring. During the movement of the positioning rod, the telescopic part can be driven to move by abutting against the anti-slip sheets on both sides, thereby ensuring the stability of the telescopic part sliding relative to the fixed part.

[0017] Optionally, a first inclined portion is provided on an outer wall of one end of the telescopic portion located inside the fixed portion, and a second inclined portion is provided on an inner wall at an opening of the fixed portion.

[0018] By adopting the above technical solution, setting the inclined surface and the second inclined surface can effectively prevent the telescopic tube from detaching from the fixed part during adjustment, thereby improving the stability of the ventilation duct. At the same time, the setting of the first inclined surface and the second inclined surface can also improve the sealing of the ventilation duct, reduce the leakage of cooling airflow, and ensure the cooling effect.

[0019] Optionally, an expansion cover is provided at one end of the telescopic portion away from the fixed portion.

[0020] By adopting the above technical solution, the expansion mask can increase the range of action of the cooling wind, thereby cooling the rooftop equipment more comprehensively, further improving the cooling effect, and ensuring the normal operation of the rooftop equipment.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The temperature sensor detects the temperature of the rooftop equipment in real time. When the detection value exceeds the preset value, the centrifugal fan will be started to extract outdoor cold air through the ventilation pipe, thereby air cooling the rooftop equipment to ensure that the rooftop equipment can be at a normal temperature, thereby ensuring the effective progress of the process;

[0023] 2. An adjustment track is set to drive the telescopic part to move, so that the ventilation duct can deliver cooling air to different areas of the roof. When there are many devices installed on the roof, different devices can be cooled, which has high flexibility and practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] The present application embodiment discloses a novel rooftop cooling air cooling device. Figure 1 , including a centrifugal fan 2 arranged outside the factory building 1 to extract outdoor cold air. The centrifugal fan 2 is connected to a ventilation pipe 3, which is arranged in a vertical direction, and its top end is horizontally bent and extends into the interior of the factory building 1, and is arranged along the bottom wall of the roof 7 of the factory building 1. In this embodiment, the ventilation pipe 3 adopts a PVC pipe with a diameter of 160 mm, which can effectively reduce high temperature assimilation and ensure the cooling effect. A control cabinet 5 is arranged in the factory building 1, and the centrifugal fan 2 is electrically connected to the control cabinet 5 to control the opening and closing of the centrifugal fan 2.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The end of the ventilation pipe 3 extending into the factory building 1 includes a fixed part 301 and a telescopic part 302. The telescopic part 302 is slidably connected to the fixed part 301. The peripheral wall of the telescopic part 302 at one end located in the fixed part 301 is integrally formed with a first inclined portion 303. The inner wall at the opening of the fixed part 301 is correspondingly provided with a second inclined portion 304. The inclination angles of the first inclined portion 303 and the second inclined portion 304 are consistent, thereby improving the connection stability between the fixed part 301 and the telescopic part 302, reducing the probability of the telescopic part 302 falling off, and improving the sealing performance.

[0033] Reference Figure 1 and Figure 2 The roof 7 is provided with a plurality of positioning rods 8, which are arranged vertically and distributed along the length direction of the ventilation pipe 3. The end of the positioning rod 8 close to the roof 7 is connected with a flange 10 by welding, and the flange 10 is provided with a plurality of locking members 11. In this embodiment, the locking members 11 are bolts for fixing the positioning rod 8; the bottom end of the positioning rod 8 is connected with a positioning ring 9 by welding, and the inner diameter of the positioning ring 9 is consistent with the outer diameter of the fixing part 301. The positioning ring 9 is sleeved on the outer wall of the fixing part 301, and its inner wall is against the outer wall of the fixing part 301; the diameter of the telescopic part 302 is smaller than the diameter of the fixing part 301, and the inner wall of the positioning ring 9 sleeved on the outside of the telescopic part 302 is rotatably connected with a plurality of balls 14, and the balls 14 are against the outer wall of the telescopic part 302, so that the friction force received by the telescopic part 302 when sliding can be effectively reduced, wear is reduced, and sliding smoothness is improved.

[0034] Reference Figure 1 and Figure 2The bottom wall of the roof 7 is provided with an adjustment track 12, which is arranged along the length direction of the ventilation pipe 3. The adjustment track 12 is slidably connected with the mounting plate 13. In this embodiment, the adjustment track 12 can adopt a screw linear module to realize the sliding of the mounting plate 13, and the positioning rod 8 away from the fixing part 301 is installed on the mounting plate 13 through its corresponding flange 10 and locking member 11, and the inner wall of its positioning ring 9 is not provided with a ball bearing 14.

[0035] Reference Figure 2 and Figure 5 Two sleeve rings 15 are provided at one end of the telescopic part 302 away from the fixed part 301. One sleeve ring 15 close to the fixed part 301 is fixed to the telescopic part 302 by welding, and the other is slidably connected to the peripheral wall of the telescopic part 302 and is connected to the other fixed sleeve ring 15 by bolts. The positioning ring 9 of the positioning rod 8 arranged on the mounting plate 13 is sleeved on the peripheral wall of the sleeve ring 15, and the end walls of the two sleeve rings 15 that are away from each other are connected with anti-slip sheets 16 by welding. The diameter of the anti-slip sheet 16 is larger than the inner diameter of the positioning ring 9 to prevent the positioning ring 9 from falling off. The abutment relationship between the positioning ring 9 and the anti-slip sheet 16 can drive the telescopic part 302 to slide relative to the fixed part 301.

[0036] Reference Figure 1 A plurality of rooftop devices 4 are arranged on the roof 7, and the rooftop devices 4 are distributed along the length direction of the adjusting track 12. A temperature sensor 6 is arranged on the rooftop device 4 to detect the temperature at the roof 7. The temperature sensor 6 is communicated with the control cabinet 5, and the control cabinet 5 controls the opening and closing of the centrifugal fan 2 based on the detection value of the temperature sensor 6; in this embodiment, the preset value is 55°C. When the detected temperature exceeds the preset value, the centrifugal fan 2 is started for air cooling until the temperature reaches below 47°C, and then the centrifugal fan 2 can be turned off; an expansion cover 17 is arranged at one end of the telescopic portion 302 away from the fixed portion 301, and the expansion cover 17 is arranged toward the direction of the rooftop device 4 to perform large-scale cooling on the rooftop device 4.

[0037] The implementation principle of a novel rooftop cooling air-cooling device in an embodiment of the present application is as follows: the temperature sensor 6 performs real-time detection, and when the detected temperature value exceeds 55°C, the adjustment track 12 is started to drive the telescopic part 302 to move, so that the expansion cover 17 of the telescopic part 302 moves to the corresponding rooftop equipment 4, and the centrifugal fan 2 is started to air-cool the rooftop equipment 4 until the temperature reaches 47°C and the centrifugal fan 2 is turned off. The air-cooling device of the present application can effectively reduce the operating temperature of the equipment in high temperature seasons and ensure stable and reliable operation of the equipment.
