A liquid outlet pipe 31 is provided at the bottom of the odor storage tank 3 to communicate with the gas pipe 1, wherein a one-way valve 310 is provided in the liquid outlet pipe 31, wherein an annular liquid distribution pipe 311 is provided at the bottom end of the liquid outlet pipe 31, wherein a plurality of nozzles 312 are provided on both sides of the annular liquid distribution pipe 311.

[0027] Reference Figure 1 A slide groove 10 and a fixed plate 12 are provided on the left side of the gas pipe 1. The top and bottom ends of the sliding plate are respectively located in the two slide grooves 10. The gas in the gas pipe 1 flows from left to right. When the gas flows therein, the sliding plate moves rightward in the slide groove 10. When it contacts the switch 13 in the fixed plate 12, the controller 5 starts the automatic odorization. The controller 5 drives the mechanism 2 to move the reciprocating piston 210 to pressurize the inside of the odor storage box 3, so that the odorant in the odor storage box 3 flows evenly into the gas pipe 1. The automatic odorization operation of the inside of the gas pipe 1 is realized without manual labor, thereby improving work efficiency.

[0028] The odorant enters the gas pipe 1 evenly mainly through the annular liquid distribution pipe 311 at the bottom of the liquid outlet pipe 31. The multiple nozzles 312 arranged on both sides of the annular liquid distribution pipe 311 further transmit the odorant and evenly disperse the odorant in the entire gas pipe 1. When the gas leaks, it can be discovered in time. At the same time, the one-way valve 310 arranged in the liquid outlet pipe 31 can prevent the gas in the gas pipe 1 from entering the odor storage box 3, avoiding the occurrence of safety hazards.

[0029] In some preferred embodiments, a sleeve 314 is provided at the center of the annular liquid dispensing tube 311, and U-shaped rods 313 are provided on both sides of the top and bottom of the sleeve 314 to connect with the annular liquid dispensing tube 311, and a rotating shaft 32 is provided inside the sleeve 314, and a plurality of blades 320 are provided on the outer circumference of the rotating shaft 32. A circle of slots 3140 are provided on the outer circumference of the sleeve 314, and the blades 320 pass through the slots 3140. A first motor 321 is also included, and the output end of the first motor 321 is connected to the rotating shaft 32.

[0030] Reference Figures 2 to 4The sleeve 314 and the U-shaped rod 313 provide accommodation space for the installation of the rotating shaft 32, which is mainly connected to the annular liquid dispensing tube 311 through the U-shaped rod 313, so as to fix both sides of the top and bottom of the sleeve 314 to prevent the rotating shaft 32 from being separated from the sleeve 314 during the transmission of the odorant. The slot 3140 arranged on the outer peripheral surface of the sleeve 314 provides space for the rotation of the blade 320. The first motor 321 drives the rotating shaft 32 to rotate in the sleeve 314, so that the blade 320 rotates, and finally the odorant passing through the nozzle 312 is evenly transmitted to various positions of the gas pipe 1 under the rotation of the blade 320, so that the user can quickly detect the leakage when a leak occurs, so as to issue an early warning.

[0031] Example 2

[0032] This embodiment 2 is implemented on the basis of embodiment 1, and the driving mechanism 2 includes a driving box 20, and a support seat 22 located above the gas pipe 1 is provided at the bottom of the driving box 20, and a pressurizing box 21 is provided inside the driving box 20, and an assembly plate 23 is provided at the bottom of the pressurizing box 21. A reciprocating screw 201 driven by a second motor 200 is provided between the assembly plate 23 and the inner wall of the driving box 20, and a moving block 202 is provided on the outer periphery of the reciprocating screw 201, and an L-shaped rod 203 is provided on the top of the moving block 202, and the end of the L-shaped rod 203 away from the second motor 200 passes through a side of the pressurizing box 21, and a piston 210 is provided inside the pressurizing box 21, and the piston 210 is connected to the L-shaped rod 203.

[0033] Reference Figure 1 The pressurization in the driving mechanism 2 is mainly achieved by the second motor 200 driving the reciprocating screw 201 to rotate. The moving block 202 arranged on the periphery of the reciprocating screw 201 drives the L-shaped rod 203 to reciprocate, so that the piston 210 moves left and right inside the pressurizing box 21, thereby increasing the pressure inside the pressurizing box 21, so that the odorant inside the odor storage box 3 enters the annular liquid distribution pipe 311 from the liquid outlet pipe 31, and is then transmitted to the inside of the gas pipe 1 in the form of mist through the nozzle 312, so that the odorization inside the gas pipe 1 is automatically operated to avoid manual operation.

[0034] It should be noted that the assembly plate 23 provides space for the installation of the reciprocating screw 201 on the one hand, and provides support for the assembly of the pressurizing box 21 on the other hand, so as to prevent the pressurizing box 21 from being displaced when the piston 210 moves.

[0035] In some preferred embodiments, a sealing ring 211 is disposed on the outer periphery of the piston 210 . The sealing ring 211 made of rubber material can effectively improve the sealing condition of the piston 210 in the pressurized box 21 .

[0036] In some preferred embodiments, a pressurizing pipe 212 is provided on the top of the pressurizing tank 21 to connect with the odor storage tank 3, and a liquid adding pipe 30 is provided on the top of the odor storage tank 3. A concentration detector 4 is provided on the top of the gas pipe 1, and the controller 5 is electrically connected to the concentration detector, the first motor 321, the second motor 200 and the switch 13 respectively.

[0037] Specifically, the pressure inside the pressurized tank 21 is transmitted through the pressurized pipe 212 to transfer the odorant inside the odor storage tank 3 from the liquid outlet pipe 31 to the inside of the gas pipe 1. At the same time, the liquid adding pipe 30 on the top of the odor storage tank 3 is connected to the odorant tank, and the liquid adding operation is performed under the condition that the odorant in the odor storage tank 3 is insufficient. The concentration detector 4 is located on the top of the gas pipe 1, and is used to detect in real time whether the odorant concentration inside the gas pipe 1 meets the preset requirements. If the odorant concentration reaches the preset requirements, this information is transmitted to the controller 5, and the controller 5 drives the first motor 321 and the second motor 200 to turn off, that is, the automatic addition of the odorant is completed, without the need for manual addition, thereby improving work efficiency and avoiding waste of resources caused by excessive addition of odorant.

[0038] When the utility model is used, when leakage occurs, the flow direction of the gas is from left to right in the gas pipe 1, so that the sliding plate moves in the slide groove 10 toward the switch 13. When the sliding plate contacts the switch 13, the controller 5 drives the second motor 200 to work, so that the L-shaped rod 203 reciprocates left and right under the action of the moving block 202 and the reciprocating screw 201, so that the piston 210 connected to the L-shaped rod 203 reciprocates in the pressurizing box 21, thereby increasing the pressure inside the pressurizing box 21, so that the odorant inside the odor storage box 3 is transmitted from the liquid outlet pipe 31 to the annular liquid distribution pipe 311 through the pressurizing pipe 212, and then transmitted to the gas pipe 1 through the nozzles 312 on both sides thereof. At the same time, the second motor 200 drives the blades 320 on the surface of the rotating shaft 32 to rotate, thereby generating a certain amount of air, so that the odorant in the gas pipe 1 is evenly distributed to all corners; after the concentration detector 4 detects that the odorant reaches the preset concentration value, it transmits this information to the controller 5, and the controller 5 drives the first motor 321 and the second motor 200 to close, completing the automatic addition of the odorant. The utility model realizes the uniform transmission of the odorant by setting an annular shunt pipe and the rotating shaft 32 and the blades 320 located inside the annular shunt pipe. At the same time, the concentration detector 4 set on the top of the gas pipe 1 stops the transportation of the odorant when the preset value is met, effectively reducing the waste of the odorant; the sliding plate is moved toward the switch 13 and contacts the switch 13 to start the automatic odorization, so that the controller 5 drives the first motor 321 and the second motor 200 to work, realizing the automatic addition of the odorant, without manual operation, greatly improving the work efficiency.

[0039] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
