Description

Technical Field

[0001] The utility model relates to the technical field of gas sampling, in particular to a full-automatic gas sampling device. Background Art

[0002] In the process of gas detection, a gas sampling device is usually required to transport the gas. The existing gas sampling devices are divided into two modes: automatic partial pressure sampling and direct sampling. When the gas is directly sampled, a heating device is required to heat the sampling tube to make better use of the sample gas.

[0003] However, in the process of heating the injection tube, as the temperature rises, it is easy to cause leakage at the connection of the injection tube. Since the gas injection is carried out in a vacuum environment, if the staff cannot discover it in time, it will not only cause the vacuum environment to fail and affect the gas delivery, but also as the gas leaks, if the gas contains harmful gases and is inhaled by the staff, it will cause damage to the staff's body and affect the staff's health.

[0004] Therefore, we proposed a fully automatic gas sampling device to solve the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present invention provides a fully automatic gas sampling device, which solves the problems raised in the above background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A fully automatic sampling device for gas comprises a manual sampling chamber and an automatic sampling chamber, wherein the automatic sampling chamber is fixedly connected to the upper end surface of the manual sampling chamber, a heating furnace is vertically slidably connected to the interior of the automatic sampling chamber, sample gas bottles are symmetrically arranged above the heating furnace, the upper ends of the sample gas bottles are fixedly connected to connecting pipes, the connecting pipes are fixedly connected to the automatic sampling chamber, the upper ends of the sample gas bottles are fixedly connected to sealing rings, the sealing rings are wrapped around the connection between the sample gas bottle and the connecting pipe, negative pressure pipes are fixedly connected between the sealing rings, a mounting bracket is fixedly connected to the negative pressure pipe, and an alarm light is fixedly connected to the upper end surface of the mounting bracket.

[0008] As a further solution of the utility model: a negative pressure column is fixedly connected above the outer surface of the negative pressure tube, a lifting rod is slidably connected through the upper end of the negative pressure column, the negative pressure column and the lifting rod are both located in a mounting frame, a button is fixedly connected to the top surface of the mounting frame, and the button is used to drive the alarm light to work.

[0009] As a further solution of the utility model: a fixed plate is fixedly connected to the outer surface of the jacking rod, and pull plates are rotatably connected to the front and rear sides of the fixed plate, and a clamping block is rotatably connected to the end of the pull plate away from the fixed plate, and a vertical plate is symmetrically fixedly connected to the upper end surface of the heating furnace, and clamping grooves are opened on the upper ends of the vertical plates, and the clamping grooves are adapted to the clamping blocks.

[0010] As a further solution of the utility model: the block is fixedly connected to a spring column on one side close to the mounting frame, a fixing column is sleeved on the outer surface of the spring column, the spring column is slidably connected in the fixing column, and the fixing column is fixedly connected to the side wall of the mounting frame at one end away from the spring column.

[0011] As a further solution of the utility model: the lower end surface of the clamping block close to the vertical plate is an inclined surface.

[0012] Beneficial effects of the utility model:

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-5 As shown, a fully automatic sampling device for gas comprises a manual sampling chamber 1 and an automatic sampling chamber 2, the automatic sampling chamber 2 is fixedly connected to the upper end surface of the manual sampling chamber 1, a heating furnace 3 is vertically slidably connected inside the automatic sampling chamber 2, sample gas bottles 18 are symmetrically arranged above the heating furnace 3, the upper ends of the sample gas bottles 18 are fixedly connected to connecting pipes 4, the connecting pipes 4 are fixedly connected to the automatic sampling chamber 2, the upper ends of the sample gas bottles 18 are fixedly connected to sealing rings 5, the sealing rings 5 ​​are wrapped around the connection between the sample gas bottles 18 and the connecting pipe 4, negative pressure pipes 6 are fixedly connected between the sealing rings 5, the negative pressure pipes 6 are fixedly connected to a mounting bracket 8, and an alarm light 9 is fixedly connected to the upper end surface of the mounting bracket 8.

[0025] like Figure 2 and Figure 4 As shown, a negative pressure column 10 is fixedly connected above the outer surface of the negative pressure tube 6, and a lifting rod 11 is slidably connected to the upper end of the negative pressure column 10. The negative pressure column 10 and the lifting rod 11 are both located in the mounting frame 8, and a button 17 is fixedly connected to the top surface of the mounting frame 8. The button 17 is used to drive the alarm light 9 to work. When gas enters the negative pressure tube 6, the gas will enter the negative pressure column 10 along the negative pressure tube 6 and push the lifting rod 11 to slide out of the negative pressure column 10. Press the button 17 to turn on the alarm light 9 to flash.

[0026] like Figure 3 and Figure 5As shown, the outer surface of the lifting rod 11 is fixedly connected to a fixed plate 12, and the front and rear sides of the fixed plate 12 are rotatably connected to pull plates 13, and the end of the pull plate 13 away from the fixed plate 12 is rotatably connected to a clamping block 19, and the upper end surface of the heating furnace 3 is symmetrically fixedly connected to the vertical plate 7, and the upper ends of the vertical plates 7 are provided with clamping grooves 14, and the clamping grooves 14 are adapted to the clamping blocks 19. During the rising process of the lifting rod 11, the clamping block 19 can be pulled out of the clamping groove 14 provided on the vertical plate 7 through the provided pull plate 13.

[0027] like Figure 3 and Figure 5 As shown, the block 19 is fixedly connected to the side of the mounting frame 8 close to the spring column 16, and the outer surface of the spring column 16 is sleeved with a fixing column 15, and the spring column 16 is slidably connected in the fixing column 15, and the end of the fixing column 15 away from the spring column 16 is fixedly connected to the side wall of the mounting frame 8. When the block 19 is squeezed, it can drive the spring column 16 to slide into the inside of the fixing column 15. When the force on the block 19 disappears, the rebound force of the spring column 16 can automatically push the block 19 to reset.

[0028] like Figure 5 As shown, the lower end surface of the block 19 close to the vertical plate 7 is an inclined surface. When the vertical plate 7 rises and contacts the block 19, the vertical plate 7 can slide along the inclined surface of the block 19 and squeeze the block 19 and the vertical plate 7 to separate.

[0029] The effects achieved by this embodiment are as follows: in the prior art, if the staff cannot discover it in time, not only will the vacuum environment fail and the gas delivery be affected, but also as the gas leaks, if the gas contains harmful gases and is inhaled by the staff, it will cause damage to the staff's body and affect the staff's health. Compared with the prior art, the gas leaked from the connection between the sample gas bottle 18 and the connecting pipe 4 can be collected in the negative pressure pipe 6, and the alarm light 9 can be triggered to flash at the same time, which not only avoids the gas in the sample gas bottle 18 from leaking into the automatic sampling chamber 2 and protects the vacuum of the automatic sampling chamber 2, but also can collect the gas leaked from the sample gas bottle 18 to avoid the gas being inhaled by the staff, thereby ensuring the safety of the staff, and can promptly remind the staff that the sample gas bottle 18 is leaking, so that the staff can take corresponding preventive measures to reduce gas leakage and minimize the harm.

[0030] Secondly, when the gas leaks and triggers the alarm light 9 to flash, the card block 19 and the card slot 14 on the vertical plate 7 can be pushed to separate, so that the heating furnace 3 can automatically descend and separate from the sample gas bottle 18, avoiding the situation where the sample gas bottle 18 leaks while the heating furnace 3 continues to heat and promote the gas transportation in the sample gas bottle 18, thereby reducing the harm of gas leakage inside the sample gas bottle 18.

[0031] The working process and principle involved in the overall content of the above embodiment are as follows:

[0032] When the staff uses the manual sample injection chamber 1, the heating furnace 3 is first driven to rise inside the manual sample injection chamber 1, driving the vertical plate 7 to rise synchronously. When the vertical plate 7 rises and contacts the card block 19, it moves along the inclined surface of the card block 19 and squeezes the card block 19, pushing the spring column 16 connected to the card block 19 to slide into the fixed column 15. When the vertical plate 7 and the card block 19 are completely separated, the spring column 16 rebounds and automatically slides out of the fixed column 15, pushing the card block 19 back to the initial position and snapping into the card slot 14 opened on the vertical plate 7, limiting the height of the heating furnace 3, and then connecting the power supply of the alarm light 9;

[0033] As the heating furnace 3 heats the sample gas bottle 18, if there is a gas leak at the connection between the sample gas bottle 18 and the connecting pipe 4, the leaked gas will enter the negative pressure pipe 6 through the sealing ring 5, and then gradually flow into the negative pressure column 10. At this time, as the gas flows into the negative pressure column 10, the lifting rod 11 will be pushed out of the negative pressure column 10 and the button 17 connected to the top surface of the mounting frame 8 will be squeezed to turn on the alarm light 9 connected to the upper end surface of the mounting frame 8 to flash. This not only avoids the gas in the sample gas bottle 18 from leaking into the automatic sampling chamber 2 and protects the vacuum of the automatic sampling chamber 2, but also can collect the gas leaked from the sample gas bottle 18 to avoid the gas being emitted and inhaled by the staff, thereby ensuring the safety of the staff, and can promptly remind the staff that the sample gas bottle 18 is leaking, so that the staff can take corresponding preventive measures to reduce gas leakage and minimize the harm.

[0034] When the lifting rod 11 slides out of the negative pressure column 10 and rises, it can synchronously drive the fixed plate 12 to rise, and drive the upper end of the pull plate 13 rotatably connected to the front and rear sides of the fixed plate 12 to rise vertically synchronously, so that the pull plate 13 moves from the inclined state to the vertical state. At this time, as the shape of the pull plate 13 changes, the pull plate 13 will pull the card block 19 to squeeze the spring column 16, so that the spring column 16 slides into the fixed column 15 again, and at the same time drives the card block 19 to slide out of the card groove 14 opened on the upper end surface of the vertical plate 7. When the limit of the card block 19 on the vertical plate 7 disappears, the heating furnace 3 will automatically descend to the bottom of the manual sampling chamber 1, so that the heating furnace 3 can automatically descend and separate from the sample gas bottle 18, avoiding the situation where the sample gas bottle 18 leaks while the heating furnace 3 continues to heat to promote the gas transportation in the sample gas bottle 18, thereby reducing the harm of gas leakage inside the sample gas bottle 18.
