In addition, when the existing ventilation device is in use, it receives the air inside the building carrying characteristic gases and acts on the bottom end of the blind plate. There are impurities such as flue gas particles in the characteristic gases. During use, some of the particulate impurities in the characteristic gases will adhere to the bottom end of the blind plate and accumulate continuously. Over time, a large amount of impurity particles will accumulate at the bottom end of the blind plate, thereby affecting the guiding effect of the air flow inside the building.

[0018] 1. A characteristic gas exhaust ventilation device described in the present invention is provided with a scraper; when the scraper moves, the top end of the scraper continuously scrapes the bottom surface of the second mask, so that the impurity particles attached to the bottom surface of the second mask fall off, and the wind direction above the building is diverse, so the wind direction received by the wind shield is different, so the receiving component will drive the scraper to move back and forth under the second mask, fully removing the impurity particles attached to the bottom surface of the second mask, avoiding the attachment and accumulation of a large number of impurity particles at the bottom of the second mask, which affects the guiding effect of the second mask on the airflow in the building.

The rainwater collected inside the water storage box enters the water outlet hole on the second mask through the water leakage hole, and then overflows through the water outlet hole. Since water has adsorption property and the amount of water overflowing through the water outlet hole is small, the rainwater will disperse from the boundary at the bottom of the water outlet hole to the bottom surface of the second mask, realizing the cleaning of the bottom surface of the second mask. Then, it falls into the discharge plate through both ends of the second mask, and finally is discharged through both ends of the discharge plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] As Figures 1 to 13 shown, a characteristic gas emission ventilation device according to an embodiment of the present invention includes a pair of brackets 1, a pair of first masks 11 are fixedly connected between the pair of brackets 1, a pair of steel beams 13 are arranged below the brackets 1, and a pair of foundation feet 12 are fixedly connected between the steel beams 13 and the brackets 1. A second mask 14 is arranged between the pair of brackets 1, and a discharge plate 15 is fixedly connected to the side of the first mask 11 and below the second mask 14;

[0037] The second mask 14 is arranged in an arc shape, a scraper 22 is slidably connected to the bottom end of the second mask 14, a receiving assembly is fixedly connected to the bottom end of the scraper 22, and a pair of guide rods 4 are fixedly connected to both sides of the receiving assembly. The end of the guide rod 4 away from the scraper 22 penetrates through the bracket 1 and is fixedly connected to a wind baffle 41;

[0038] When the existing ventilation device is in use, it receives the air carrying characteristic gas inside the building and acts on the bottom end of the mask. There are impurities such as flue gas particles in the characteristic gas. During use, some of the particulate impurities in the characteristic gas will adhere to the bottom end of the mask and accumulate continuously. Over time, a large amount of impurity particles will accumulate at the bottom end of the mask, thereby affecting the guiding effect of the air flow in the building. To solve the above problems, the embodiment of the present invention is provided with structures such as a scraper 22 and a wind baffle 41. The specific use process is as follows: When in use, the ventilation device is installed at the air outlet at the top of the building. Specifically, the steel beam 13 is fixed to the top of the building; the steel beam 13 is connected to the bracket 1 through the anchor 12; when the air carrying characteristic gas inside the building is discharged outward, the air surges towards the bottom end of the second mask 14. The second mask 14 disperses the received air to both sides, and then it is received by the first mask 11 and finally dissipated into the air. When the wind blows above the building, the wind force will act on the surface of the wind baffle 41. When the wind baffle 41 is affected by the wind force, it will drive the guide rod 4 to move. The guide rod 4 drives the receiving assembly to move synchronously below the second mask 14. The receiving assembly drives the scraper 22 to move synchronously. When the scraper 22 moves, the top end of the scraper 22 continuously scrapes the bottom surface of the second mask 14, so that the impurity particles attached to the bottom surface of the second mask 14 fall off. Since the wind direction above the building is diverse, the direction of the wind force received by the wind baffle 41 is different. Therefore, the receiving assembly will drive the scraper 22 to reciprocate below the second mask 14, fully removing the impurity particles attached to the bottom surface of the second mask 14, and avoiding a large amount of impurity particles from adhering to and accumulating at the bottom end of the second mask 14, which affects the guiding effect of the second mask 14 on the air flow in the building.

[0039] The receiving assembly includes a collection box 2. A pair of springs 21 are fixedly connected between the inner wall of the collection box 2 and the bottom end of the scraper 22. The end of the guide rod 4 is fixedly connected to the side surface of the collection box 2; both ends of the collection box 2 are located above the discharge plate 15; when the scraper 22 scrapes off the impurity particles attached to the bottom end of the second mask 14, the impurity particles will fall downward into the collection box 2, preventing the impurity particles falling off from the bottom surface of the second mask 14 from falling back into the building interior and causing pollution to the interior space of the building.

[0040] Fixing plates 23 are fixedly connected to both ends of the scraper 22. A plurality of intercepting plates 141 are fixedly connected to both ends of the second mask 14. When the scraper 22 drives the fixing plates 23 to move, the fixing plates 23 are intermittently intercepted by the intercepting plates 141, and the fixing plates 23 are bent when intercepted; when the collection box 2 moves, the scraper 22 drives the fixing plates 23 to move synchronously. When the fixing plates 23 move, the fixing plates 23 are intermittently intercepted by the intercepting plates 141, and the fixing plates 23 are bent when intercepted. Therefore, the fixing plates 23 will oscillate intermittently, driving the scraper 22 at the bottom end to vibrate synchronously. Since the scraper 22 is connected to the collection box 2 through the springs 21, the scraper 22 is not firmly fixed and can vibrate sufficiently to vibrate the impurity particles attached to the surface into the collection box 2.

[0041] A pair of arc-shaped plates 3 are fixedly connected to the top end of the collection box 2. An arc-shaped groove 31 is opened at the top end of the arc-shaped plate 3. A rotating bar 32 is rotatably connected inside the arc-shaped groove 31. The rotating bar 32 is made of a flexible material and continuously contacts the bottom end of the second mask 14. When the collection box 2 moves, the arc-shaped plate 3 at the top end of the collection box 2 moves synchronously. The rotating bar 32 in the arc-shaped groove 31 at the top end of the arc-shaped plate 3 adheres to the bottom end of the second mask 14 and moves synchronously. The rotating bar 32 rotates during movement and will not scrape off the impurity particles on the bottom surface of the second mask 14. Moreover, the rotating bar 32 cooperates with the arc-shaped plate 3 and the second mask 14 to block both sides of the collection box 2, preventing the impurity particles falling off from the bottom surface of the second mask 14 from falling outside the collection box 2, ensuring the collection effect of the collection box 2 on the impurity particles on the bottom surface of the second mask 14. And the rotating bar 32 is made of corrosion-resistant rubber to ensure the service life of the rotating bar 32.

[0042] A rotating shaft 25 is inserted through the bottom end of the collection box 2. A plurality of windshields 24 are fixedly connected to one end of the rotating shaft 25 located at the bottom of the collection box 2. A rotating plate 26 is fixedly connected to one end of the rotating shaft 25 located inside the collection box 2. Under the action of wind, the windshields 24 drive the rotating plate 26 to rotate inside the collection box 2 through the rotating shaft 25. When the rotating plate 26 rotates inside the collection box 2, an air flow will be generated inside the collection box 2. The air flow can drive the impurity particles collected inside the collection box 2 to move towards both ends, and fall into the discharge plate 15 through both ends of the collection box 2, and finally be discharged through the discharge plate 15. Specifically, the discharge plate 15 can receive rainwater, and the collected impurity particles are discharged towards both ends through the rainwater.

[0043] A water storage box 5 is fixedly connected to the top end of the second mask 14. A water receiving head 51 is communicated with the top end of the water storage box 5. A water leakage hole is opened at the bottom end of the water storage box 5. An outlet hole aligned with the water leakage hole is opened on the surface of the second mask 14. A plug block 54 is inserted inside the water leakage hole. A connecting rod 53 is fixedly connected to the top end of the plug block 54. A floating rod 52 is fixedly connected to the top end of the connecting rod 53. The floating rod 52 is located inside the water receiving head 51. When it rains, rainwater enters the water storage box 5 through the water receiving head 51. When the water storage box 5 is filled with rainwater, the rainwater will continue to be injected into the water receiving head 51. When the floating rod 52 is submerged, the floating rod 52 drives the plug block 54 at the bottom end of the connecting rod 53 to move upward through buoyancy, so that the water leakage hole at the bottom end of the water storage box 5 is opened. The rainwater collected inside the water storage box 5 enters the outlet hole on the second mask 14 through the water leakage hole, and then overflows through the outlet hole. Since water has adsorption and the amount of water overflowing through the outlet hole is small, the rainwater will disperse towards the bottom surface of the second mask 14 through the boundary at the bottom end of the outlet hole, realizing the cleaning of the bottom surface of the second mask 14. Then it falls into the discharge plate 15 through both ends of the second mask 14, and finally is discharged through both ends of the discharge plate 15.

[0044] A separation net 6 is fixedly connected to the top end of the water connection head 51; this prevents sundries such as leaves from blocking the water connection head 51.

[0045] A scraping blade 20 is slidably connected to the top end of the discharge plate 15, and a linkage rod is fixedly connected between the top end of the scraping blade 20 and the collection box 2; when the collection box 2 moves, the collection box 2 drives the scraping blade 20 to move synchronously through the linkage rod. When the scraping blade 20 moves, it scrapes off the impurity particles deposited on the discharge plate 15, preventing the impurity particles from depositing on the discharge plate 15 and affecting the use effect; the scraping blade 20 is made of a corrosion-resistant alloy; ensuring a long service life.
