[0039] The driving device includes a belt 13, a driving motor 14, a driving gear 1401 and a driven roller 1402; the driving gear 1401 and the driven roller 1402 are rotatably connected to the connecting plate 1403, the driving motor 14 is fixedly installed below the connecting plate 1403, and it drives the driving gear 1401, and the bottom of the driving motor 14 is fixed to the bottom of the machine room 10; the bottom of the guide shell 1 is rotatably connected to the machine room 10 through a turntable 15, and a tooth groove 12 is embedded in the outer wall of the bottom end; the belt 13 is meshed and connected with the tooth groove 12 of the outer wall of the bottom end of the guide shell 1, and the belt 13 is clamped between the driving gear 1401 and the driven roller 1402; by turning on the driving motor 14 to drive the driving gear 1401 to rotate, when the driving gear 1401 rotates, it can drive the belt 13 to transmit, because the bottom of the guide shell 1 is connected to the bottom of the machine room 10 through the turntable 15, so that the four guide shells 1 can rotate synchronously.
[0040] Furthermore, in this embodiment, a partition 906 is fixedly connected to the bottom end of the machine room 10, and the partition 906 is suspended and fixed at the bottom end of the machine room 10, and a plurality of through holes 908 are opened inside the partition 906; through the setting of the partition 906, the electrical control equipment inside the machine room 10 can be suspended, thereby facilitating the increase of air fluidity.
[0041] The lower middle end of the partition 906 is supported by setting a plurality of top columns 909, and suction fans 907 are fixedly installed at the two ends below it. The air outlet duct of the suction fan 907 passes through the machine room 10 and extends to the outside. Through the setting of the suction fan 907, the flow of air can be accelerated, which is beneficial to the ventilation inside the machine room 10, thereby making it easier to protect the internal devices of the machine room 10.
[0042] Specifically, during use, when ventilation and protection of the devices inside the machine room 10 are required, the blower 901 in the DC system can blow air directly below the inside of the machine room 10 to perform air conditioning. Combined with the partition 906 and its internal through holes 908 and the suction fan 907, the flow of air in the central part of the machine room can be accelerated, which is beneficial to ventilation inside the machine room 10, thereby making it easier to protect the devices inside the machine room 10.
[0043] Then, through the blower 904, the delivery duct 905 and the guide shell 1 in the circulation system, a surrounding airflow can be generated around the machine room 10, thereby facilitating the flow of air and thus being more conducive to air conditioning and ventilation.

Since the bottom of the guide shell 1 is connected to the bottom of the machine room 10 through the turntable 15, the four guide shells 1 can rotate synchronously, so that the direction of the air outlet can be adjusted synchronously. Example 3
[0045] See also Figure 4-10 On the basis of the above-mentioned embodiment, in the air-cooled unit air conditioning ventilation protection device, the interior of the guide shell 1 is set as a hollow cylinder, and a plurality of rectangular holes 101 are evenly spaced on the side of the guide shell 1, and a protective net 2 is provided in each rectangular hole 101; the function of these rectangular holes is to exhaust air and circulate air, so as to realize an effective air exchange process. In order to protect the safety of people and equipment, a protective net 2 is provided in each rectangular hole 101, and the guide shell 1, the rectangular hole 101 and the protective net 2 are a whole, and this structure is completed by injection molding process.
[0046] Sliding parts are arranged at intervals at the upper and lower parts inside the guide shell 1, and the sliding parts are slide rails 3 and automatic slide seats 4, and the automatic slide seats 4 are slidably connected to the slide rails 3; when the slide rails 3 are fixed, there is a distance between them and the inner wall of the guide shell 1, and both sides of the upper and lower slide rails 3 are fixedly connected to the inner wall of the guide shell 1 through L-shaped plates 5.
[0047] The inner wall of the guide shell 1 is fitted with an arc-shaped sliding plate 6, and both sides of the sliding plate 6 are provided with L-shaped clamping plates 7, and the closed ends of the L-shaped clamping plates 7 are fixedly connected to the automatic sliding seat 4. An arc-shaped anti-slipping strip 8 is provided below the sliding plate 6, so that both sides of the filter screen are clamped in the L-shaped clamping plates 7, and the bottom is supported on the anti-slipping strip 8.
[0048] The sliding plate 6 is provided with a number of rectangular ventilation holes 601 at equal intervals. The upper and lower parts of the sliding plate 6 are movably connected to the inside of the guide shell 1 through sliding parts. The ventilation holes 601 are arranged corresponding to the rectangular holes 101 when the sliding parts are translated, so that when the guide shell 1 stops running, the sliding plate 6 is translated by the sliding parts to cover the rectangular holes 101.
[0049] Specifically, when in use, multiple ventilation holes 601 are evenly spaced on the sliding plate 6, and L-shaped cardboards 7 are provided on both sides of the sliding plate 6, so that the automatic slide 4 can drive the sliding plate 6 to move when running on the slide rail 3. After moving to a suitable position, the ventilation holes 601 are arranged corresponding to the rectangular holes 101. When the guide shell 1 stops running, the automatic slide 4 drives the ventilation holes 601 on the sliding plate 6 to stagger with the rectangular holes 101, and covers the rectangular holes 101 to prevent dust from entering and affecting the operation of the internal equipment when the guide shell 1 is not in use. The anti-slip strip 8 is arranged below the sliding plate 6 and is in an arc shape. The main function is to prevent the filter from falling off between the L-shaped cardboards 7. The two sides of the filter are tightly clamped by the L-shaped cardboards 7, and the anti-slip strip 8 prevents it from falling off, ensuring that a good sealing effect can be maintained even when the air conditioner is not in operation. In addition, the anti-slip strip 8 also plays a supporting role, making the filter more stable and reliable.
[0050] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.
[0051] The working principle and specific use process of the air-cooled unit air conditioning ventilation protection device are as follows: when the components inside the machine room 10 need to be ventilated and regulated, the blower 901 in the DC system can blow air directly below the inside of the machine room 10 to perform air conditioning. In combination with the partition 906 and its internal through hole 908 and the suction fan 907, the fluidity of the air in the central part of the machine room can be accelerated, which is beneficial for ventilation inside the machine room 10, thereby making it easier to protect the components inside the machine room 10. Then, through the blower 904, the conveying pipe 905 and the guide shell 1 in the circulation system, an air flow can be generated around the machine room 10, thereby making it easier for air to flow and making it easier for air conditioning and ventilation. At the same time, by turning on the drive motor 14, it drives the drive gear 1401 to rotate. When the drive gear 1401 rotates, it can drive the belt 13 to transmit. Since the bottom of the guide shell 1 is connected to the bottom of the machine room 10 through the turntable 15, the four guide shells 1 can rotate synchronously, so that the direction of the air outlet can be adjusted synchronously.
[0052] In addition, multiple ventilation holes 601 are evenly spaced on the sliding plate 6 in the guide shell 1, and the sliding plate 6 can be moved to a suitable position so that the ventilation holes 601 are arranged corresponding to the rectangular hole 101. When the guide shell 1 stops running, the automatic slide seat 4 drives the ventilation holes 601 on the sliding plate 6 to stagger with the rectangular hole 101, and covers the rectangular hole 101, so as to prevent dust from entering and affecting the operation of the internal equipment when the guide shell 1 is not in use. At the same time, the anti-slip strip 8 is arranged below the sliding plate 6 and is in an arc shape. The main function is to prevent the filter from falling off between the L-shaped card plate 7. The two sides of the filter are tightly clamped by the L-shaped card plate 7, and are prevented from falling off by the anti-slip strip 8, so as to ensure that a good sealing effect can be maintained even when the air conditioner is not in operation. In addition, the anti-slip strip 8 also plays a supporting role, making the filter more stable and reliable.
