[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] First embodiment:

[0019] See also Figure 1-2 ,in, Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is a front view of the first embodiment of the utility model.

[0020] The utility model provides a bottled liquefied petroleum gas safety alarm cut-off device, comprising a tank body 101, a round tube 102, a valve 103, a measuring mechanism, a pressure gauge 104 and a roarer 105, wherein the measuring mechanism comprises a connecting pipe 106, a pressure sensor 107, a first gear 108, a second gear 109, a motor 110 and a connecting assembly, wherein the connecting assembly comprises a fixed pipe 111 and a threaded shell 112. The above-mentioned scheme solves the problem that when an oil leak is detected, an alarm is sounded, but the bottled liquefied petroleum gas cannot be sealed immediately, and needs to be closed after artificial discovery, which has certain limitations.

[0021] According to the present specific embodiment, the round tube 102 is fixedly connected to the tank body 101 and is located above the tank body 101. The valve 103 is connected to the round tube 102 and is located above the round tube 102. The connecting assembly is arranged between the round tube 102 and the connecting tube 106. The connecting tube 106 is communicated with the round tube 102 and is located on one side of the tank body 101. The pressure sensor 107 is fixedly connected to the connecting tube 106 and is located on the surface of the connecting tube 106. The first gear 108 is fixedly connected to the valve 103 and is located below the valve 103. The motor 110 is connected to the connecting tube 106. The tank body 101 is fixedly connected and located on one side of the valve 103. The second gear 109 is fixedly connected to the motor 110 and located above the motor 110. The first gear 108 is meshed with the second gear 109. The pressure sensor 107 detects the pressure of the connecting pipe 106. If a leakage occurs, the pressure of the pressure sensor 107 changes and transmits an electrical signal to the motor 110. The motor 110 drives the second gear 109 to rotate, and the second gear 109 drives the first gear 108 to rotate, so that the valve 103 rotates accordingly, the tank body 101 is closed, and the safety is improved.

[0022] Among them, the pressure gauge 104 is fixedly connected to the pressure sensor 107 and is located on one side of the pressure sensor 107. The roarer 105 is fixedly connected to the pressure sensor 107 and is located on one side of the pressure sensor 107. When there is no leakage, the pressure gauge 104 is the same as the pressure inside the connecting pipe 106. After a leakage occurs, the roarer 105 sounds an alarm to remind the personnel. The valve 103 closes the tank body 101, and the air pressure inside the connecting pipe 106 is smaller than the external atmospheric pressure. The pressure gauge changes accordingly. If the personnel do not discover it in the first time, they can also judge the situation by observing the pressure gauge.

[0023] Secondly, the fixed tube 111 is fixedly connected to the circular tube 102 and is located on one side of the circular tube 102. One end of the threaded shell 112 is clamped with the connecting tube 106. The other end of the threaded shell 112 is threadedly connected to the fixed tube 111 and is sleeved on the surface of the fixed tube 111. The connecting tube 106 is installed in the threaded shell 112, and the threaded shell 112 is connected to the fixed tube 111, thereby improving the air tightness.

[0024] When using the utility model, the connecting pipe 106 is installed in the threaded shell 112, and the threaded shell 112 is connected to the fixed pipe 111. The pressure sensor 107 detects the pressure of the connecting pipe 106. If a leak occurs, the roarer 105 sounds an alarm, the pressure of the pressure sensor 107 changes, and an electrical signal is transmitted to the motor 110. The motor 110 drives the second gear 109 to rotate, and the second gear 109 drives the first gear 108 to rotate, so that the valve 103 rotates accordingly, and the tank body 101 is closed. The air pressure inside the connecting pipe 106 is smaller than the external atmospheric pressure, and the barometer changes accordingly, thereby improving safety.

[0025] Second embodiment:

[0026] See also Figure 3-4 ,in, Figure 3 It is a schematic diagram of the overall structure of the second embodiment of the utility model. Figure 4 The utility model Figure 3 Schematic diagram of the structure at point A.

[0027] On the basis of the first embodiment, the utility model provides a bottled liquefied petroleum gas safety alarm cut-off device, which also includes a fixing assembly, wherein the fixing assembly includes a sliding plate 201, a fixing plate 202, four threaded rods 203 and four nuts 204. Through the arrangement of the above-mentioned structure, the threaded shell 112 is fixed to prevent the threaded shell 112 from rotating and loosening, thereby improving the air tightness.

[0028] According to the present specific implementation, the fixing assembly is disposed on one side of the threaded shell 112 , and the fixing assembly fixes the threaded shell 112 , so that the threaded shell 112 will not become loose, thereby improving stability.

[0029] Among them, the middle section of the fixed tube 111 is set in a square shape, the sliding plate 201 is slidably connected to the fixed tube 111 and covered on the surface of the fixed tube 111, the fixed plate 202 is fixedly connected to the threaded shell 112 and is located on the outside of the threaded shell 112, one end of the four threaded rods 203 is fixedly connected to the fixed plate 202, the other ends of the four threaded rods 203 pass through the sliding plate 201, and the four nuts 204 are threadedly connected to the corresponding threaded rods 203 and are located on one side of the sliding plate 201. After the fixed shell is fixed, the sliding plate 201 is slid so that the four threaded rods 203 pass through the sliding plate 201, and the sliding plate 201 is fixed to the four threaded rods 203 by the nuts 204. Since the middle section of the fixed tube 111 is set in a square shape, the sliding plate 201 fixes the threaded shell 112 so that it cannot rotate, thereby improving stability.

[0030] When using the utility model, the connecting pipe 106 is installed in the threaded shell 112, the threaded shell 112 is connected to the fixed pipe 111, the sliding plate 201 is slid so that the four threaded rods 203 pass through the sliding plate 201, and the sliding plate 201 is fixed to the four threaded rods 203 by the nut 204. Since the middle section of the fixed pipe 111 is located in a square setting, the sliding plate 201 fixes the threaded shell 112 and cannot rotate. The pressure sensor 107 detects the pressure of the connecting pipe 106. If a leak occurs, the roarer 105 sounds an alarm, the pressure of the pressure sensor 107 changes, and an electrical signal is transmitted to the motor 110. The motor 110 drives the second gear 109 to rotate, and the second gear 109 drives the first gear 108 to rotate, so that the valve 103 rotates accordingly, and the tank body 101 is closed. The air pressure inside the connecting pipe 106 is smaller than the external atmospheric pressure, and the barometer changes accordingly.

[0031] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
