[0004] At present, although the existing gas valve wells with leakage detection can detect small gas leaks by covering the entire pipeline, this method increases the manufacturing cost and concentrates the gas together. If it is not handled properly during maintenance, it is easy to cause major accidents. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a gas valve well with leakage detection, aiming to improve the gas valve well with leakage detection. Under normal circumstances, the overall covering of the gas pipe will increase the manufacturing cost and the centralized processing of gas is prone to accidents.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a gas valve well with leakage detection, comprising a gas spreading structure and a gas collecting structure, the gas collecting structure comprising a gas collecting part and a detection part, the detection part is fixed on the top of the gas collecting part, the gas collecting part comprises a gas collecting ring, the gas collecting ring is fixed on one side of the gas spreading structure, a gas collecting hole is opened on one side of the gas collecting ring, a connecting pipe is fixed on one side of the connecting pipe, a conveying pipe is fixed on one side of the conveying pipe, a support plate is fixed on one side of the conveying pipe, and a battery is fixed on the top of the support plate.

[0008] In one embodiment of the utility model, the air diffusion structure includes a valve well body, a well cover is sleeved on one side of the valve well body, a ventilation hole is opened on one side of the well cover, a solar panel is fixed inside the valve well body, and a protective cover is fixed inside the valve well body.

Since the air hole 212 is close to the gas pipe 115, it will preferentially extract the air near the gas pipe 115. A connecting pipe 213 is fixed on one side of the gas collecting ring 211. The connecting pipe 213 connects many gas collecting rings 211. A delivery pipe 214 is fixed on one side of the connecting pipe 213. The delivery pipe 214 serves to connect the connecting pipe 213 and the docking pipe 221. A support plate 215 is fixed on one side of the delivery pipe 214. A battery 216 is fixed on the top of the support plate 215. The battery 216 serves to store electrical energy.

[0023] See also Figure 1-2The gas dispersion structure 100 includes a valve well body 110, a manhole cover 111 is sleeved on one side of the valve well body 110, and a vent hole 112 is opened on one side of the manhole cover 111. The vent holes 112 are responsible for air intake and air outlet. A solar panel 113 is fixed inside the valve well body 110, and a protective cover 114 is fixed inside the valve well body 110. The protective cover 114 is transparent and strong and pressure-resistant, so as to protect the solar panel 113. A gas pipe 115 is fixed inside the valve well body 110, and a valve body 116 is fixed at the end of the gas pipe 115. A handle 117 is rotatably connected inside the valve body 116. A gas dispersion structure 100 includes a gas pipe 115, a gas pipe 115, a gas pipe 116 ... Part 120, the air dispersing part 120 includes a partition 121, the partition 121 plays a role of supporting the motor 125, and preventing the air extracted by the fan blade 126 from being dispersed into the valve well body 110, the partition 121 is fixed inside the well cover 111, an air inlet 122 is opened on the top of the partition 121, a partition bar 123 is fixed on the top of the partition 121, the partition bar 123 divides the space between the well cover 111 and the partition 121 into four areas, so that the air intake and the air outlet are unrelated, a support bar 124 is fixed inside the partition 121, a motor 125 is fixed at the bottom of the support bar 124, and a fan blade 126 is fixed to the output shaft end of the motor 125.

[0024] See also Figure 1 and Figure 3-4 The detection member 220 includes a butt joint tube 221, which is fixed on the top of the support plate 215. An amplifying tube 222 is fixed at the end of the butt joint tube 221. The amplifying tube 222 can extract enough air when the fan blade 227 is running, thereby avoiding the motor 226 occupying part of the internal space of the butt joint tube 221 due to its own volume. A protective net 223 is fixed inside the amplifying tube 222, a gas detector 224 is fixed at the bottom of the protective net 223, a supporting bar 225 is fixed inside the amplifying tube 222, a motor 226 is fixed at the bottom of the supporting bar 225, and a fan blade 227 is fixed at the output shaft end of the motor 226.

[0025] Specifically, the working principle of the gas valve well with leakage detection is as follows: when in use, the solar panel 113 can convert light energy into electrical energy and store it in the battery 216, and then the battery 216 supplies power to the motor 125 and the motor 2 226. Under normal conditions, only one of the motors 125 is started, thereby driving the fan blade 126 to extract the air in the valve well body 110 and transport it to the top of the partition 121, and then discharge it through the air vent 112. At the same time, because the air is extracted, the outside air will enter from the air vent 112 elsewhere, and then enter the valve well body 110 through the air inlet 122, so that the valve well body 110 is not leaking through the air flow. It will be too humid, and the motor 226 is always running, thereby driving the fan blade 227 to rotate. Because the fan blade 227 is in the amplifying tube 222, the air flow it drives can only discharge the air in the amplifying tube 222 outward, thereby causing the air in the valve well body 110 to enter the gas collecting ring 211 through the gas collecting hole 212, and then enter the delivery pipe 214 through the connecting pipe 213, and finally enter the amplifying tube 222 through the docking pipe 221. At this time, the air will blow towards the gas detector 224 to determine whether the extracted air contains gas. If so, the two motors 125 will run at high speed and send the information of gas leakage to the background data.

[0026] It should be noted that the specific model specifications of motor 1 125 and motor 2 226 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0027] The power supply and principle of the motor 1 125 and the motor 2 226 are clear to those skilled in the art and will not be described in detail here.

[0028] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
