Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust valve technology, and in particular to a hydraulically supported plate type smoke exhaust valve. Background Technology

[0002] The hydraulic support plate type smoke exhaust valve is a type of valve used in mechanical smoke exhaust systems. It is mainly composed of valve body, valve leaf, shaft and bushing, actuator, seals and other components.

[0003] The applicant discovered through a search that a Chinese patent discloses a "hydraulic support plate type smoke exhaust valve" with publication number "CN202301983U". This patent includes a smoke exhaust valve body, a rotatable panel, and a rotating shaft. The rotatable panel is mounted on the smoke exhaust valve body via the rotating shaft. The drive mechanism of the smoke exhaust valve body is connected to the panel mechanism connecting shaft of the rotatable panel. The patent also includes a hydraulic support component connecting the smoke exhaust valve body and the rotatable panel. This invention, by installing a hydraulic support component between the smoke exhaust valve body and the rotatable panel, ensures that the supporting force remains constant throughout the entire working stroke of the panel rotation. It also provides cushioning performance, avoiding impact when the rotatable panel opens and closes. The invention features lifting, support, and gravity balance, and offers advantages such as convenient installation, safe use, and no maintenance required.

[0004] However, if the existing device is turned on directly, the airflow will increase, but the filter will become clogged if it cannot be cleaned quickly after a long period of operation. This will prevent the filter from removing particulate impurities in the air, allowing dirty air to enter the human body. This will keep the human body in a state of breathing dirty air, and the damage caused to the human body will be irreversible. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulically supported plate type smoke exhaust valve to solve the problem mentioned in the background art, where dust blockage cannot be quickly cleaned, causing people to breathe dirty air continuously.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulically supported plate type smoke exhaust valve, including a support frame, an installation groove on one side of the support frame surface, a dustproof mesh frame that is easy to disassemble and clean on one side of the support frame surface, a clamping structure that enables quick disassembly of the dustproof mesh frame on both sides of the support frame surface, and a smoke exhaust structure that is fixedly connected to the opposite sides of the inner wall of the installation groove, which can directly adjust the internal angle by rotation to adjust the smoke exhaust efficiency.

[0007] Preferably, the dustproof mesh frame includes a barrier net, extension blocks, and docking grooves. The barrier net is located on one side inside the dustproof mesh frame, and the two extension blocks are fixedly connected to one side of the surface of the dustproof mesh frame. The two docking grooves are opened on both sides of the surface of the two extension blocks.

[0008] Preferably, both of the clamping structures include a fixing block and an extension rod. The fixing block is fixedly connected to one side of the surface of the bearing frame, and the extension rod is slidably connected inside the fixing block.

[0009] Preferably, both clamping structures further include a limiting groove and a pushing plate. The limiting groove is formed on one side of the surface of the bearing frame, and the pushing plate is slidably connected to the inside of the limiting groove.

[0010] Preferably, both clamping structures further include a spring and a clamping rod. The spring is fixedly connected to the opposite side of the fixing block and the push plate, and the spring is sleeved on the wall of the extension rod. The clamping rod is fixedly connected to the bottom surface of the push plate, and the bottom end of the clamping rod is paired with the inner wall of the mating groove.

[0011] Preferably, the smoke exhaust structure includes a mounting plate, a sliding plate, and louvers. The mounting plate is fixedly connected to the opposite side of the inner wall of the mounting groove, the sliding plate is slidably connected to one side of the inner wall of the mounting groove, and a plurality of louvers are fixedly connected to one side of the surface of the sliding plate.

[0012] Preferably, the smoke exhaust structure further includes a rectangular block, an adjusting block, and a connecting block. The rectangular block is fixedly connected to one side of the surface of the support frame, the adjusting block is rotatably connected to one side of the surface of the rectangular block, and the connecting block is rotatably connected to the opposite side of the adjusting block and the sliding plate.

[0013] Preferably, limit blocks are fixedly connected to both sides of the inner wall of the mounting groove, and the limit blocks are located on one side of the dustproof mesh frame.

[0014] The technical effects and advantages of this utility model are as follows: This utility model utilizes the rotation of the adjusting block to allow multiple louvered fans to adjust their angles by raising and lowering the sliding plate. This allows the louvered fans to adjust the angle of their blades according to different smoke exhaust environments. At the same time, the extension rod is used to release the locking rod from the docking groove, allowing the dustproof mesh frame to be quickly disassembled and cleaned. This avoids the problem that most devices lack the ability to adjust the smoke exhaust angle to increase or decrease smoke exhaust efficiency and the ability to quickly disassemble the dustproof mesh frame. This improves the flexibility of use and adds the practicality of quick disassembly of the dustproof mesh frame, allowing people to always breathe fresh air. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] like Figures 1 to 5 As shown, a hydraulically supported plate type smoke exhaust valve in the first aspect embodiment of this utility model includes a support frame 1, an installation groove 2 is provided on one side of the surface of the support frame 1, a dustproof mesh frame 3 that can be easily disassembled and cleaned is provided on one side of the surface of the support frame 1, and a clamping structure 4 that enables the dustproof mesh frame 3 to be quickly disassembled is fixedly connected to both sides of the surface of the support frame 1. A smoke exhaust structure 5 is fixedly connected to the opposite sides of the inner wall of the installation groove 2, and the smoke exhaust efficiency can be adjusted by directly rotating the internal angle.

[0023] The technical effects achieved by the above embodiments are as follows: This utility model utilizes the rotation of the adjusting block 505 to enable multiple louvered fans 503 used in conjunction to adjust the angle of the louvered fans 503 by raising and lowering the sliding plate 502. This allows the louvered fans 503 to adjust the angle of the fan blades according to different smoke exhaust environments. At the same time, by lifting the extension rod 402, the locking rod 406 is released from the locking state with the docking groove 303, allowing the dustproof mesh frame 3 to be quickly disassembled and cleaned. This avoids the problem that most devices do not have the function of adjusting the smoke exhaust angle to increase or decrease the smoke exhaust efficiency and quickly disassembling the dustproof mesh frame 3, thus improving the flexibility of use and adding the practicality of quick disassembly of the dustproof mesh frame 3, allowing people to always be in a state of breathing fresh air. Example

[0024] like Figure 1 and Figure 3 As shown, a hydraulically supported plate type smoke exhaust valve includes all the contents of Embodiment 1. In addition, the dustproof mesh frame 3 includes a blocking mesh 301, an extension block 302, and a docking groove 303. The blocking mesh 301 is located on one side inside the dustproof mesh frame 3. The two extension blocks 302 are fixedly connected to one side of the surface of the dustproof mesh frame 3. The two docking grooves 303 are opened on both sides of the surface of the two extension blocks 302.

[0025] The technical effects achieved by the above embodiments are as follows: the direct installation of the barrier net 301 enables the dustproof net frame 3 to filter impurities in the flue gas using the barrier net 301, while the opening of the docking groove 303 enables the dustproof net frame 3 to not only isolate and prevent dust but also facilitate disassembly. Example

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a hydraulically supported plate type smoke exhaust valve includes all the contents of Embodiment 2. In addition, both clamping structures 4 include a fixing block 401 and an extension rod 402. The fixing block 401 is fixedly connected to one side of the surface of the support frame 1, and the extension rod 402 is slidably connected to the inside of the fixing block 401. Both clamping structures 4 also include a limiting groove 403 and a pushing plate 404. The limiting groove 403 is opened on one side of the surface of the support frame 1, and the pushing plate 404 is slidably connected to the inside of the limiting groove 403. Both clamping structures 4 also include a spring 405 and a clamping rod 406. The spring 405 is fixedly connected to the opposite side of the fixing block 401 and the pushing plate 404, and the spring 405 is sleeved on the rod wall of the extension rod 402. The clamping rod 406 is fixedly connected to the bottom surface of the pushing plate 404, and the bottom end of the clamping rod 406 is paired with the inner wall of the mating groove 303.

[0027] The technical effect achieved by the above embodiment is as follows: by lifting the extension rod 402, the extension rod 402 drives the bottom push plate 404 to slide inside the limiting groove 403. While sliding, the spring 405 is deformed, so that the clamping rod 406 at the bottom of the push plate 404 can be moved out from the inside of the docking groove 303, thereby releasing the clamping effect and enabling the dustproof net frame 3 to be quickly disassembled, thereby cleaning the dust on the surface of the barrier net 301. Example

[0028] like Figure 2 and Figure 5 As shown, a hydraulically supported plate type smoke exhaust valve includes all the contents of Embodiment 3. In addition, the smoke exhaust structure 5 includes a mounting plate 501, a sliding plate 502, and louvers 503. The mounting plate 501 is fixedly connected to the opposite side of the inner wall of the mounting groove 2. The sliding plate 502 is slidably connected to one side of the inner wall of the mounting groove 2. Multiple louvers 503 are fixedly connected to one side of the surface of the sliding plate 502. The smoke exhaust structure 5 also includes a rectangular block 504, an adjusting block 505, and a connecting block 506. The rectangular block 504 is fixedly connected to one side of the surface of the bearing frame 1. The adjusting block 505 is rotatably connected to one side of the surface of the rectangular block 504. The connecting block 506 is rotatably connected to the opposite side of the adjusting block 505 and the sliding plate 502.

[0029] The technical effect achieved by the above embodiment is as follows: Subsequently, the rectangular block 504 provided on one side of the surface of the mounting plate 501 is used to make the adjusting block 505 rotatably connected to the surface of the rectangular block 504 rotate. When the adjusting block 505 rotates, one end of the adjusting block 505 will drive the connecting block 506 to rotate and move. Once the connecting block 506 rotates, the sliding plate 502 rotatably connected on one side will produce a lifting effect. However, while the sliding plate 502 is lifting, the louver fan 503 fixedly connected to its surface will eventually adjust the angle so that the smoke exhaust effect can be supported by the angle adjustment. Example

[0030] like Figure 2 As shown, a hydraulically supported plate type smoke exhaust valve includes all the contents of embodiment 4. In addition, limit blocks 6 are fixedly connected to both sides of the inner wall of the mounting groove 2, and the limit blocks 6 are located on one side of the dustproof mesh frame 3.

[0031] The technical effect achieved by the above embodiments is that the setting of the limiting block 6 produces a limiting effect when the dustproof mesh frame 3 is inserted into the mounting groove 2.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
