Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to a gas leakage linked door and window alarm system. Background Art

[0002] Doors and windows are openings in a building, usually used to provide access, ventilation and lighting. Doors are used for entry and exit, and windows are used for light transmission and ventilation. Doors and windows are usually made of frames, glass or other materials, and can meet the needs of beauty and functionality through different designs and styles.

[0003] For example, the "a door and window" with the publication number of CN103711407B is composed of at least a first door and window body and a second door and window body, wherein the first door and window body and the second door and window body each include an upper frame, a lower frame, a left frame, a right frame and a door and window substrate, wherein the upper frame, the lower frame, the left frame and the right frame are connected to form a frame structure for installing the door and window substrate; at least one of the upper frame and the lower frame is provided with a buckle part, wherein the first door and window body and the second door and window body are buckled with each other through the buckle part to form a hollow groove, wherein a sliding mechanism is installed in the hollow groove, wherein the first door and window body and the second door and window body can move independently through the sliding mechanism. By adopting the present invention, the door and window structure is simple and compact, the space utilization rate is high, the door and window body has both flat push and smooth opening and closing functions, and can save space, and is convenient to install and clean.

[0004] However, in the prior art, although this type of door and window has the advantages of simple and compact structure, high space utilization, flat push and smooth opening and closing functions, space saving, easy installation, and easy cleaning, it is lacking in preventing gas leakage. Since this type of door and window does not have a gas leakage alarm function, it means that people need to rely on external gas leakage alarms or other equipment to detect leaks. However, if there is no independent gas leak detector or alarm device installed in the home, once a leak occurs, there may be a slow response, delaying emergency treatment. The delayed response may lead to catastrophic consequences such as poisoning, fire or explosion. If no one is at home, once the gas leaks, the closed doors and windows will cause the indoor methane concentration to increase rapidly. When the methane concentration is higher than 5%, the methane will explode when it encounters electrical equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a gas leak linked door and window alarm system to solve the problem that the doors and windows proposed in the above background technology do not have the function of alarming when gas leaks, thereby causing catastrophic consequences such as poisoning, fire or explosion in the home.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, by setting a threshold value for the methane detector, when the indoor methane concentration reaches 3%, the methane detector will transmit a signal to the control module and sound an alarm. At this time, the control module will drive the block B to move upward through the electric push rod B. After the block B slides away from the surface of the glass frame B, the electric push rod A will drive the block A to move upward. After the block A is away from the spring, the spring will slide on the surface of the limit rod A under the elastic force of the spring. After the spring bounces the glass window A, the glass window A will be driven by gravity to rotate the connecting rod A. At this time, the connecting rod B will also rotate through the connecting shaft. After the glass window A contacts the positioning stop rod, the glass window A can be opened, so that the indoor gas can be discharged through the glass window A, thereby avoiding poisoning, fire or even explosion caused by the closing of doors and windows when the gas leaks.

[0018] 2. In the present invention, when the methane detector detects that the methane concentration in the room has risen, the control module will turn on the bidirectional motor B, and the bidirectional motor B will drive the gear A to rotate. When the gear A rotates, it will drive the toothed plate to move in the storage groove, and the toothed plate will drive the bracket to slide inside the limiting side plate. At this time, the roller B will roll inside the limiting groove B. After the bracket drives the fan to move to the top of the glass window A, the fan can be turned on, so that the indoor gas can be quickly discharged through the fan. After the methane detector detects that the gas concentration is above 4%, it will control the fan and the home electrical equipment to be turned off through the control module, so as to prevent the indoor gas from contacting the electrical equipment when it is close to the explosion index and causing an explosion.

[0019] 3. In the present invention, the motor B drives the screw rod A to rotate, and the screw rod A drives the gear B to rotate when rotating. When the gear B rotates, it drives the gear C to rotate through the toothed chain, and the gear C drives the transmission rod to rotate, and the transmission rod drives the screw rod B to rotate. As the screw rods A and B rotate, the screw rods A and B drive the push blocks A and B to move on the outer frame, so that the glass frame A and the glass frame B are closed. After the glass frame A and the glass frame B are closed, the glass window A and the glass window B can be rotated to open the top of the glass window A and the glass window B. Because the density of methane is less than that of air, when gas leaks, methane will generally fill the indoor ceiling. At this time, opening the top of the glass window A and the glass window B is much more efficient than sliding the glass frame to a general opening mode to disperse the gas.

The design of the moving hole 114 ensures that when the glass frame A102 is slid, a rotating block A121 on its surface will move through the moving hole 114, thereby not blocking the movement of the glass frame A102. A positioning stopper 115 is fixedly installed at the bottom of the glass frame A102 and the glass frame B103. An electric push rod A116 is fixedly installed on the inner surface of the glass frame A102, and a stopper A117 is installed on the output end of the electric push rod A116. A limit rod A118 is fixedly installed on the inner surface of the glass frame A102, and a spring 119 is slidably connected to the surface of the limit rod A118. A rotating stopper 115 is inserted into the interior of the glass frame A102. Block A121, a methane detector 122 is fixedly installed on the surface of the outer frame 100, a control module 123 is fixedly installed inside the outer frame 100, an electric push rod B124 is fixedly installed inside the inner frame 101, a stopper B125 is installed on the output end of the electric push rod B124, the inner surfaces of the glass frames A102 and B103 are rotatably connected with glass windows A104 and B105 respectively, the top surfaces of the glass frames A102 and B103 are both provided with limit blocks 106 and rollers A107, the number of limit grooves A108 is two groups, the number of connecting rods A111, connecting rods B113 and connecting shafts 112 is four groups, and the four groups of connecting rods A111, connecting rods B113 and connecting shafts 112 are Evenly distributed on the sides of the glass window A104 and the glass window B105, the surface of the limit rod A118 is sleeved with a spring 120, the roller A107 is rollingly connected with the limit groove A108, and the design of the roller A107 and the limit groove A108 at the top facilitates the sliding of the glass frame A102 and the glass frame B103 while also facilitating the cleaning of the bottom surface of the inner frame 101, thereby avoiding the situation where the limit groove A108 is set at the bottom and the dust inside is difficult to clean, the limit block 106 is slidingly connected with the inner frame 101, the connecting rod B113 is rotationally connected with the connecting shaft 112, the methane detector 122 is electrically connected with the control module 123, and the sealing gasket 110 is made of natural rubber.The natural rubber material design of the sealing gasket 110 increases the sealing effect of the connection between the glass window A104 and the glass frame A102, the glass window B105 and the glass frame B103 when the glass window A104 and the glass window B105 are closed. The connecting rod A111 and the connecting rod B113 are slidably connected between the glass frame A102 and the glass frame B103, the spring 119 is slidably connected to the inner frame 101, and the spring 120 is slidably connected to the limit rod A118. The rotating block A121 and the limiting rod A118 are connected by threads. The threaded connection design of the rotating block A121 and the limiting rod A118 facilitates the replacement of the spring 120 by disassembling the rotating block A121, thereby preventing the spring 120 from weakening under long-term stress. The stopper A117 slides between the glass frame A102 and the spring sheet 119, and the stopper B125 slides between the glass frame B103 and the glass window B105.

[0037] By setting a threshold value for the methane detector 122, when the methane concentration in the room reaches 3%, the methane detector 122 will transmit a signal to the control module 123 and sound an alarm. At this time, the control module 123 will drive the block B125 to move upward through the electric push rod B124. After the block B125 slides away from the surface of the glass frame B103, the electric push rod A116 will drive the block A117 to move upward. After the block A117 is away from the spring 119, the spring 119 will be acted on by the elastic force of the spring 120. The surface of the limit rod A118 slides, and after the spring piece 119 pops the glass window A104 open, the glass window A104 will be driven by gravity to rotate the connecting rod A111, and at this time the connecting rod B113 will also rotate through the connecting shaft 112, and the glass window A104 can be opened after it contacts the positioning stopper 115, so that the gas in the room can be discharged through the glass window A104, thereby avoiding poisoning, fire or even explosion caused by the closed doors and windows when the gas leaks;

[0038] By rotating the rotating block A121, after the rotating block A121 is unscrewed from the limiting rod A118, the rotating block A121 can be pulled out from the glass window A104. After the rotating block A121 is pulled out from the glass frame A102, the spring 120 can be pulled out from the glass window A104, and then a new spring 120 can be sleeved on the surface of the limiting rod A118. After the new spring 120 is installed, the rotating block A121 can be inserted into the glass frame. At this time, the rotating block A121 can be rotated again, and the spring 120 can be replaced after the rotating block A121 is connected to the limiting rod A118 through threads.

[0039] Embodiment 2: Figure 10-11 As shown, the inner surface of the outer frame 100 is provided with a storage groove 200, and the design of the storage groove 200 has the effect of storing the bracket 203 and the fan 205, thereby reducing the space occupied by the bracket 203 and the fan 205 when not in operation, and at the same time has a beautiful effect. The side of the storage groove 200 is fixedly installed with a limited side plate 201, and the surface of the limited side plate 201 is provided with a limited groove B202. The inside of the storage groove 200 is provided with a bracket 203, and the side of the bracket 203 is rotatably connected with a roller B204. The inside of the bracket 203 is fixed A fan 205 is installed, a tooth plate 206 is fixedly installed on the side of the bracket 203, a bidirectional motor A207 is fixedly installed inside the outer frame 100, a gear A208 is installed on the output end of the bidirectional motor A207, the bracket 203 is slidingly connected to the limiting side plate 201, the roller B204 is rollingly connected to the limiting groove B202, the bracket 203 is slidingly connected to the storage groove 200, the gear A208 is rotationally connected to the outer frame 100, the gear A208 is meshed with the tooth plate 206, and the tooth plate 206 is slidingly connected to the outer frame 100.

[0040] In this embodiment, when the methane detector 122 detects that the methane concentration in the room has risen, the control module 123 will turn on the bidirectional motor B300, and the bidirectional motor B300 will drive the gear A208 to rotate. When the gear A208 rotates, it will drive the tooth plate 206 to move in the storage slot 200, and the tooth plate 206 will drive the bracket 203 to slide inside the limiting side plate 201. At this time, the roller B204 will roll inside the limiting slot B202. After the bracket 203 drives the fan 205 to move to the top of the glass window A104, the fan 205 can be turned on, so that the indoor gas can be quickly discharged through the fan 205. After the detector detects that the gas concentration is above four percent, the control module 123 will control the fan 205 and the electrical equipment in the home to be turned off, so as to prevent the indoor gas from contacting the electrical equipment when it is close to the explosion index and causing an explosion.

[0041] Embodiment 3: According to Figure 12-13As shown, a motor B300 is fixedly installed inside the outer frame 100, a screw rod A301 is installed at the output end of the motor B300, a gear B302 is fixedly installed at the end of the screw rod A301 away from the motor B300, a gear C304 is rotatably connected inside the outer frame 100, a transmission rod 305 is fixedly installed on the surface of the gear C304, a screw rod B306 is fixedly installed at the end of the transmission rod 305 away from the gear B302, a push block A303 and a push block B307 are slidably connected inside the outer frame 100, a toothed chain 308 is sleeved on the surfaces of the gear B302 and the gear C304, the gear A208 is rotatably connected to the outer frame 100, the screw rod B306 is rotatably connected to the outer frame 100, the push block A303 and the screw rod A301 are threadedly connected, the push block B307 and the screw rod B306 are threadedly connected, and the gear B302 and the gear C304 are both meshed with the toothed chain 308.

[0042] In this embodiment, the motor B300 drives the screw rod A301 to rotate, and the screw rod A301 drives the gear B302 to rotate when rotating. When the gear B302 rotates, it drives the gear C304 to rotate through the toothed chain 308. The gear C304 drives the transmission rod 305 to rotate, and the transmission rod 305 drives the screw rod B306 to rotate. As the screw rods A301 and B306 rotate, the screw rods A301 and B306 drive the push blocks A303 and B307 to move on the outer frame 100. Move to close the glass frame A102 and the glass frame B103. After the glass frame A102 and the glass frame B103 are closed, the glass windows A104 and the glass window B105 can be rotated to open the tops of the glass windows A104 and the glass window B105. Because the density of methane is less than that of air, when gas leaks, methane will generally fill the indoor ceiling. At this time, opening the tops of the glass windows A104 and the glass windows B105 is much more efficient in dispersing the gas than sliding the glass frames to the normal opening method.

[0043] The use method and working principle of the device: when the glass frame A102 or the glass frame B103 needs to be opened, the glass frame A102 is slid. When the glass frame A102 moves, it drives the limit block 106 to slide inside the inner frame 101. At this time, the limit block 106 drives the roller A107 to roll inside the limit groove A108. At this time, the function of pushing the glass window A104 to open can be realized, and at the same time, the situation that dust accumulation inside the limit groove makes it difficult to clean can be avoided.

[0044] When gas leaks indoors, the methane detector 122 will control the opening of the glass window A104 or glass window B105 through a pre-set threshold. When the indoor methane concentration reaches 3%, the methane detector 122 will transmit a signal to the control module 123 and sound an alarm. At this time, the control module 123 will drive the block B125 to move upwards through the electric push rod B124. After the block B125 slides away from the surface of the glass frame B103, the electric push rod A116 will drive the block A117 to move upwards. After the block A117 is away from the shrapnel 119, The spring 119 will slide on the surface of the limit rod A118 under the elastic force of the spring 120. After the spring 119 pops the glass window A104 open, the glass window A104 will be driven by gravity to rotate the connecting rod A111. At this time, the connecting rod B113 will also rotate through the connecting shaft 112. After the glass window A104 contacts the positioning stopper 115, the glass window A104 can be opened, so that the indoor gas can be discharged through the glass window A104, thereby avoiding poisoning, fire or even explosion caused by the closed doors and windows when the gas leaks.

[0045] When the spring 120 on the limit rod A118 needs to be replaced, the rotating block A121 only needs to be rotated. After the rotating block A121 is rotated away from the limit rod A118, the rotating block A121 can be pulled out from the glass window A104. After the rotating block A121 is pulled out from the glass frame A102, the spring 120 can be pulled out from the glass window A104, and then a new spring 120 is sleeved on the surface of the limit rod A118. After the new spring 120 is installed, the rotating block A121 can be inserted into the glass frame. At this time, the rotating block A121 is rotated again. After the rotating block A121 is connected to the limit rod A118 through a thread, the spring 120 can be replaced.

[0046] When the methane detector 122 detects that the indoor methane concentration continues to rise, the control module 123 will turn on the bidirectional motor B300, and the bidirectional motor B300 will drive the gear A208 to rotate. When the gear A208 rotates, it will drive the tooth plate 206 to move in the storage slot 200, and the tooth plate 206 will drive the bracket 203 to slide inside the limiting side plate 201. At this time, the roller B204 will roll inside the limiting slot B202. After the bracket 203 drives the fan 205 to move to the top of the glass window A104, the fan 205 can be turned on, so that the indoor gas is quickly discharged through the fan 205. After the detector detects that the gas concentration is above 4%, the fan 205 and the electrical equipment in the home will be controlled to be turned off through the control module 123, so as to prevent the indoor gas from contacting the electrical equipment when it is close to the explosion index and causing an explosion;

[0047] When the glass frame A102 and the glass frame B103 need to be closed, it is only necessary to turn on the motor B300, and the motor B300 will drive the screw rod A301 to rotate, and the screw rod A301 will drive the gear B302 to rotate when rotating, and the gear B302 will drive the gear C304 to rotate through the toothed chain 308, and the gear C304 will drive the transmission rod 305 to rotate, and the transmission rod 305 will drive the screw rod B306 to rotate, and as the screw rods A301 and B306 rotate, the screw rods A301 and B306 will drive the push blocks A303 and B306 to rotate. Block B307 moves on the outer frame 100, thereby closing the glass frame A102 and the glass frame B103. After the glass frame A102 and the glass frame B103 are closed, the glass windows A104 and the glass windows B105 can be rotated to open the tops of the glass windows A104 and the glass windows B105. Because the density of methane is less than that of air, when gas leaks, methane will generally fill the indoor ceiling. At this time, opening the tops of the glass windows A104 and the glass windows B105 is much more efficient in dispersing the gas than sliding the glass frames to the normal opening method.
