Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation equipment technology, specifically to a ventilator with an upper sliding valve plate structure. Background Technology
[0002] In industrial plants, warehouses, and some large buildings, ventilation systems play a crucial role in maintaining fresh indoor air, removing harmful gases, and regulating temperature and humidity. Currently, a variety of ventilators are available on the market.
[0003] However, the existing technology has the following drawbacks:
[0004] Currently, most ventilator valves on the market have a downward sliding or rotating structure. With this type of valve, the valve can only regulate the air volume. However, rainwater or sand can enter the room after falling onto the valve, failing to prevent rain or snow from entering. After long-term use, the bottom sliding valve will accumulate dust, which is difficult to clean, affecting the ventilation effect and potentially causing the valve to not close tightly, further reducing the performance of the ventilator. Utility Model Content
[0005] The purpose of this utility model is to provide a ventilator with an upper sliding valve plate structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilator with an upper sliding valve plate structure, comprising a ventilator body and a rainproof canopy. The top two ends of the ventilator body are fixedly connected to the bottom two ends of the rainproof canopy. A ventilation opening is provided on the top of the ventilator body, and a flat valve plate is slidably installed inside the ventilation opening. Guide rails and push rod seats are sequentially fixedly installed on the inner walls of the bottom sides of the rainproof canopy. The open end of the guide rail is located in the middle of the side away from the side plate of the rainproof canopy, and the bottom of the guide rail is fixedly connected to the top of the ventilator body. A push rod is provided in the middle of one end of the push rod seat, and the push rod extends and retracts inside the guide rail. A bearing is sleeved on the outer side of the push rod away from the push rod seat. A protrusion is provided in the middle of the bearing near the opening side of the guide rail. Two clamping plates are provided at one end of each side of the top of the flat valve plate, and the protrusion is engaged between the two clamping plates.
[0007] The above technical solution, in which the flat valve plate is located at the opening on the top of the ventilator body, opens and closes by sliding, effectively isolating rainwater and snowflakes and preventing them from entering the interior of the ventilator body.
[0008] The protrusion has threaded through holes in the middle of the end away from the bearing and in the middle of the top of the clamping plate, and the threaded through holes of the two are correspondingly opened. The clamping plate and the protrusion are fixedly connected by bolts, and the bolt ends are threaded with fastening nuts. The bearing is a block shape with an inner circle and an outer square. The inner ring of the bearing has several positioning grooves evenly opened, and several protruding ridges are evenly distributed on the outer side of the push rod away from the push rod seat.
[0009] The above technical solution involves the bearing inner ring positioning groove engaging with the convex ridge to prevent relative rotation between the bearing and the push rod, thus ensuring smooth movement of the flat valve plate.
[0010] The bottom of the inner walls on both sides of the rainproof canopy are fixedly equipped with protective covers, which are placed on the outside of the guide rail. The protective cover has an L-shaped interface and rectangular plates at both ends. The length and width of the rectangular plates are the same as the length and width of the protective cover cross-section.
[0011] The above technical solution uses a protective cover that is placed on the outside of the guide rail, which protects the push rod from being hit or damaged by wind and snow.
[0012] The bottom of the protective cover is provided with a sliding strip, and the top of the flat valve plate is provided with a second sliding groove on both sides, and the two ends of the second sliding groove are designed to be open. The sliding strip is slidably installed inside the second sliding groove.
[0013] The above technical solution, with its open ends on both sides of the second slide groove, prevents it from affecting the sliding of the flat valve plate.
[0014] The top of the inner walls on both sides of the vent is provided with a first sliding groove, and the first sliding groove is designed to be open at the end near the push rod seat. The top of the inner wall on the side of the vent away from the push rod seat is provided with a slot. The flat valve plate is provided with a slider at the end near the clamping plate on both sides. The slider is slidably installed inside the first sliding groove.
[0015] By adopting the above technical solution, the slot can ensure that the flat valve plate fits tightly against the side wall of the vent when closed, thus improving the sealing performance.
[0016] The flat valve plate has a raised strip in the middle of the side near the clamping plate. The raised strip is snapped into the inside of the slot. Sealing strips are glued to the three sides of the flat valve plate that are in contact with the vent. A groove is opened on the top of the vent near the push rod seat.
[0017] By adopting the above technical solution, the sealing strip improves the sealing performance of the flat valve plate, and the groove depth is the same as the thickness of the flat valve plate.
[0018] A fixing plate is provided on the outer side of the ventilator body at a distance from the top. The fixing plate is a rectangular ring plate with rounded chamfers on all its edges. Mounting holes are provided at all four corners of the fixing plate. A base is fixedly installed in the middle of the inner side of the ventilator body through four connecting rods. Ventilation fans are provided in the middle of both ends of the base.
[0019] In this technical solution, the ventilator body is fixedly connected to the building ventilation duct via a fixing plate.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] This utility model places the sliding valve plate at the top ventilation opening of the ventilator body. When the sliding valve plate is closed, it can fit tightly against the inner wall of the ventilation opening, effectively preventing rainwater from entering the ventilator from the top, avoiding rainwater backflow, protecting the indoor environment and equipment safety. The electric push rod makes the sliding valve plate open and close smoothly, not easily vibrating, and not easily condensing. Even if condensation occurs, it can be collected into the lower water tank. Moreover, the valve plate push rod is outdoors, which is convenient for maintenance. Attached Figure Description
