Description

Technical Field

[0001] This invention relates to the field of turret fan technology, specifically to a manual / automatic turret fan device and its usage method. Background Technology

[0002] When artillery shells are fired, the turret compartments generate a large amount of smoke and harmful substances. A turret fan system is needed to extract these substances and vent them outside, ensuring air quality inside the turret. Currently, domestically produced turret fan systems use electrically controlled valves for opening and closing, lacking manual operation or the ability to select between manual and automatic operation (i.e., a manual-automatic hybrid system). Furthermore, turret fans are primarily used in army artillery. For amphibious applications, seawater can easily enter the artillery equipment during exhaust or intake. To address these shortcomings, a solution is proposed.

[0003] In traditional solutions, when a valve needs to be closed, the central control system first receives the action request. Based on this request, the system sends action commands to the fan and the bidirectional angle electromagnet. Upon receiving the commands, the fan and the bidirectional angle electromagnet begin their actions, ultimately closing the valve. In this process, there is a response time required from the system receiving the command to issuing the command, and then to the bidirectional angle electromagnet receiving the command and the motor actuating, resulting in a slow valve response. Furthermore, the device must close the air vent within a specified time of 0.15 seconds after receiving the command; if it fails to close within this time, smoke will enter the driver-operated vehicle.

[0004] Traditional solutions are mainly used in army artillery weapons. However, for amphibious applications, due to the large waves at sea, seawater can easily enter the interior of the artillery weapon equipment through the turret fan device during ventilation or air intake. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to solve the problems of limited functionality and slow response of existing traditional solutions.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A manual / automatic integrated turret fan device includes: a waterproof cover 100, a cavity 200, a hinged plate 300, and a ventilation device 400; the cavity 200 is located inside the waterproof cover 100 and connected to the waterproof cover 100; and an movable gap 1200 is provided on the inner wall of the waterproof cover 100 corresponding to the opening end of the cavity 200; the hinged plate 300 is located within the movable gap 1200.

[0008] The ventilation device 400 includes a manual drive device 410, an automatic drive device 420, a accumulating spring element 430, and a stabilizing suction device 440; the non-handle end of the manual drive device 410 is fixedly connected to the opening and closing plate 300; the telescopic end of the automatic drive device 420 faces the opening and closing plate 300; one end of the plurality of accumulating spring elements 430 is fixedly connected to the opening and closing plate 300, and the other end is fixedly connected to the cavity 200.

[0009] The manual drive device 410 and the automatic drive device 420 can drive the opening and closing plate 300 to separate from or close the opening end of the cavity 200. When separating, multiple energy-storing elastic elements 430 are in a stretched and energy-storing state, and a stabilizing suction device 440 is used to maintain the separated state. When closing, multiple energy-storing elastic elements 430 quickly contract, driving the opening and closing plate 300 to close quickly.

[0010] Advantages: The automatic drive unit opens automatically when the ventilation fan starts and closes automatically when the fan stops, achieving the ventilation function. Simultaneously, a manual drive unit allows for manual opening and closing of the shut-off mechanism, providing an emergency switch in case of electric control failure or vehicle power outage, thus improving the product's reliability and safety. Multiple accumulating spring components are in a tension-accumulating state during ventilation, enabling rapid closure of the vents when ventilation is not needed.

[0011] In one embodiment of the present invention, a first skirt 201 and a second skirt 202 are provided along the inner wall of the cavity 200; the first skirt 201 is located at the opening end of the cavity 200; the second skirt 202 divides the cavity 200 longitudinally into a first receiving cavity 210 and a second receiving cavity 220; and the non-connecting ends of the second receiving cavity 220 and the first receiving cavity 210 are arranged in a grid-like perforated configuration.

[0012] In one embodiment of the present invention, the non-handle end of the manual drive device 410 passes sequentially through the bottom of the second receiving cavity 220, the second skirt 202, and the first skirt 201 of the cavity 200 and is fixedly connected to the opening and closing plate 300; the automatic drive device 420 is fixedly located in the cavity 200 through the second skirt 202.

[0013] In one embodiment of the present invention, the stabilizing suction device 440 includes a first mounting bracket 441, a second mounting bracket 442, a suction block 443, and a suction plate 444, arranged sequentially according to the direction in which the opening plate 300 separates from or closes the opening end of the cavity 200; wherein...

[0014] One end face of the first mounting bracket 441 is fixedly connected to the first skirt 201, one end of the second mounting bracket 442 is spherically connected to the other end face of the first mounting bracket 441, and can rotate within the first mounting bracket 441; the suction block 443 is fixedly connected to the other end of the second mounting bracket 442; the suction plate 444 is located in the first receiving cavity 210 of the cavity 200 and is fixedly connected to the manual drive device 410.

[0015] In one embodiment of the present invention, the manual drive device 410 or the automatic drive device 420 lifts the opening and closing plate 300, causing the opening and closing plate 300 to disengage from the opening end of the cavity 200, and the state of the stable suction device 440 is as follows:

[0016] When the manual drive device 410 lifts the opening and closing plate 300, it simultaneously drives the suction plate 444 to lift, gradually approaching the suction block 443, and finally making the suction plate 444 and the suction block 443 in a suction state; the suction plate 444 and the suction block 443 in the suction state maintain the opening and closing plate 300 in a state of being disengaged from the opening end of the cavity 200.

[0017] When the automatic drive device 420 lifts the opening and closing plate 300, the automatic drive device 420 itself maintains the opening and closing plate 300 in a disengaged state from the opening end of the cavity 200; or adjusts its own extension length, and when the opening and closing plate 300 is lifted, it drives the manual drive device 410 to lift, so that the suction plate 444 is lifted synchronously, and finally the suction plate 444 and the suction block 443 are in a suction state. Through the suction plate 444 and the suction block 443 in the suction state, the opening and closing plate 300 is maintained in a disengaged state from the opening end of the cavity 200.

[0018] In one embodiment of the present invention, the opening end of the opening plate 300 and the cavity 200 are kept in a closed state, which is achieved in two ways, including:

[0019] The manual drive device 410 pulls down the opening and closing plate 300, closing the opening and closing plate 300 and the opening end of the cavity 200, simultaneously separating the suction plate 444 from the suction block 443; and,

[0020] When the suction block 443 is energized, the attraction force disappears, and the suction plate 444 separates from the suction block 443. Under the action of multiple energy storage elastic elements 430 and gravity, the opening end of the opening plate 300 and the cavity 200 are closed.

[0021] In one embodiment of the present invention, one side of the suction block 443 relative to the suction plate 444 is parallel to the suction surface of the suction plate 444.

[0022] In one embodiment of the present invention, a fan 221 is provided inside the second receiving cavity 220.

[0023] The present invention also provides a method of using a manual / automatic turret fan device, comprising:

[0024] When ventilation is required, the system commands cause the telescopic end of the automatic drive device 420 to extend and lift, causing the opening and closing plate 300 to disengage from the opening end of the cavity 200, thus achieving the ventilation function. At the same time, multiple energy-storing elastic elements 430 are stretched and in a stored state. When closed, the telescopic end of the automatic drive device 420 retracts, and the multiple energy-storing elastic elements 430, under the action of their own force and gravity, quickly bring the opening and closing plate 300 into contact with the cavity 200.

[0025] In one embodiment of the present invention, in an emergency, the manual drive device 410 is lifted to disengage the opening plate 300 from the opening end of the cavity 200, thereby achieving ventilation. At the same time, the manual drive device 410 is lifted to engage the stabilizing suction device 440), maintaining the state where the opening plate 300 is disengaged from the opening end of the cavity 200. Pulling down the manual drive device 410 causes the opening plate 300 to adhere to the opening end of the cavity 200, while the stabilizing suction device 440) disengages.

[0026] Compared with the prior art, the beneficial effects of the present invention are: at the same time, the electromagnet is made more flexible and a spherical support surface is added above the electromagnet, which can adaptively adjust the electromagnet's attraction angle according to the actual angle of the attraction surface, effectively ensuring that the cover plate and the magnet's attraction surface are in close contact, and ensuring that the magnet and the cover plate are in close contact and attraction, effectively solving the problem of insufficient magnet attraction caused by sand and dust distribution on the electromagnet's contact surface.

One end of each of the accumulating spring elements 430 is fixedly connected to the opening and closing plate 300, and the other end is fixedly connected to the cavity 200.

[0035] The manual drive device 410 and the automatic drive device 420 can cause the opening and closing plate 300 to disengage from or close the opening end of the cavity 200. When disengaging, multiple accumulating elastic elements 430 are in a stretched and accumulating state, and the stabilizing suction device 440 is used to maintain the disengaged state. When closing, the multiple accumulating elastic elements 430 retract rapidly, causing the opening and closing plate 300 to close rapidly. Specifically, the automatic drive device 420 is an electric push rod.

[0036] Please see Figures 1 to 3 As shown, in one embodiment of the present invention, the waterproof cover 100 and the cavity 200 are detachably connected. Multiple first baffles 110 are provided on the inner wall of the waterproof cover 100, and multiple second baffles 203 are provided on the outer wall of the cavity 200. The multiple first baffles 110 and multiple second baffles 203 are staggered to form a wave-proof structure, so that the turret fan device has waterproof and wave-proof functions and can be used on amphibious artillery weapons and equipment. At the same time, while having wave-proof function, it does not affect the air intake and exhaust wind force.

[0037] Please see Figures 1 to 3As shown, in one embodiment of the present invention, a first skirt 201 and a second skirt 202 are provided along the inner wall of the cavity 200. The first skirt 201 is located at the opening end of the cavity 200, and the second skirt 202 divides the cavity 200 longitudinally into a first receiving cavity 210 and a second receiving cavity 220. The non-connecting ends of the second receiving cavity 220 and the first receiving cavity 210 are arranged in a grid-like perforated pattern. A fan 221 is provided inside the second receiving cavity 220.

Furthermore, a controller 213 is fixedly installed within the first receiving cavity 210, capable of controlling the switching on / off state and forward / reverse rotation of the fan 221, as well as the operating state of the automatic drive device 420.

[0039] Please see Figures 1 to 4 As shown, in one embodiment of the present invention, specifically, the non-handle end of the manual drive device 410 passes through the bottom of the second receiving cavity 220, the second skirt 202, and the first skirt 201 of the cavity 200 in sequence and is fixedly connected to the opening and closing plate 300, and the automatic drive device 420 is fixedly located in the cavity 200 through the second skirt 202.

[0040] The stabilizing suction device 440 includes a first mounting bracket 441, a second mounting bracket 442, a suction block 443, and a suction plate 444, arranged sequentially according to the direction of separation or closure of the opening end of the opening plate 300 and the cavity 200. One end face of the first mounting bracket 441 is fixedly connected to the first skirt 201. One end of the second mounting bracket 442 is spherically connected to the other end face of the first mounting bracket 441 and is rotatable within the first mounting bracket 441. The suction block 443 is fixedly connected to the other end of the second mounting bracket 442. The suction plate 444 is located within the first receiving cavity 210 of the cavity 200 and is fixedly connected to the manual drive device 410. By adjusting the position of the second mounting bracket 442 within the first mounting bracket 441, one side of the suction block 443 relative to the suction plate 444 is parallel to the suction surface of the suction plate 444, increasing the suction force and preventing separation, thus causing the opening plate 300 to close. Meanwhile, a stabilizing suction device 440 is placed inside the cavity 200 to prevent dust from accumulating on the surfaces of the suction block 443 and suction plate 444, thus reducing the attractive force. Specifically, the suction block 443 and suction plate 444 are magnets.

[0041] Please see Figures 1 to 4As shown, in one embodiment of the present invention, the manual drive device 410 or the automatic drive device 420 lifts the opening and closing plate 300, causing the opening and closing plate 300 to disengage from the opening end of the cavity 200, and the state of the stable suction device 440 is as follows:

[0042] When the manual drive device 410 lifts the opening and closing plate 300, it simultaneously drives the suction plate 444 to lift, gradually approaching the suction block 443, and finally making the suction plate 444 and the suction block 443 in a suction state; the suction plate 444 and the suction block 443 in the suction state maintain the opening and closing plate 300 in a state of being disengaged from the opening end of the cavity 200.

[0043] When the automatic drive device 420 lifts the opening and closing plate 300, the automatic drive device 420 itself maintains the opening and closing plate 300 in a disengaged state from the opening end of the cavity 200, or adjusts its own extension length. When the opening and closing plate 300 is lifted, it drives the manual drive device 410 to lift, so that the suction plate 444 is lifted synchronously, and finally the suction plate 444 and the suction block 443 are in a suction state. Through the suction plate 444 and the suction block 443 in the suction state, the opening and closing plate 300 is maintained in a disengaged state from the opening end of the cavity 200.

[0044] Please see Figures 1 to 4 As shown, in one embodiment of the present invention, the opening end of the opening plate 300 and the cavity 200 are kept in a closed state by two methods, including:

[0045] The manual drive device 410 pulls down the opening and closing plate 300, closing the opening and closing plate 300 and the opening end of the cavity 200, simultaneously separating the suction plate 444 from the suction block 443. Then, energizing the suction block 443 eliminates the attraction force, causing the suction plate 444 to separate from the suction block 443. Under the force of multiple stored elastic elements 430 and gravity, the opening and closing plate 300 and the opening end of the cavity 200 are closed.

[0046] More specifically, the turret fan device also includes an electrical connector 500 located at the bottom of the second receiving cavity 220, for supplying power and signals to the electrical equipment inside the turret fan device, such as the controller 213, the fan 221, and the automatic drive device 420. In use, the turret fan device is mounted on the turret vent, and a rubber pad 204 is provided at the contact point with the turret vent.

[0047] Please see Figures 1 to 4 As shown, the present invention also provides a method for using a manual / automatic integrated turret fan device, comprising:

[0048] When ventilation is required, the system commands the extension end of the automatic drive device 420 to extend and lift, causing the opening and closing plate 300 to disengage from the opening end of the cavity 200, thus achieving ventilation. At the same time, multiple energy-accumulating spring components 430 are stretched and in a stored state. When closed, the extension end of the automatic drive device 420 retracts, and the multiple energy-accumulating spring components 430, under the action of their own force and gravity, quickly bring the opening and closing plate 300 into contact with the cavity 200, preventing air from entering or leaving the turret through the device.

[0049] In an emergency, the manual drive device 410 is raised to disengage the opening plate 300 from the opening end of the cavity 200, enabling ventilation. Simultaneously, the raised manual drive device 410 engages the stabilizing suction device 440, maintaining the disengagement of the opening plate 300 from the opening end of the cavity 200. Pulling down the manual drive device 410 causes the opening plate 300 to re-engage with the opening end of the cavity 200, while the stabilizing suction device 440 disengages, preventing air from entering or leaving the turret through this device.
