Description

Technical Field

[0001] This utility model belongs to the technical field of geological body collection, specifically relating to a hot spring gas sample collection device. Background Technology

[0002] Hot springs are typically located in areas of frequent crustal activity, making it difficult to directly observe and monitor geological conditions from the surface. However, deep within the earth, gases escape from fissures created by crustal movement. By collecting these gases from deep within the crust and analyzing their composition, geological conditions can be discerned.

[0003] In existing technology, a gas collection bottle connected to a gas delivery tube is typically inverted in the hot spring water. Gas overflowing from the water is collected by downward drainage, and then drawn into a collection bag via a syringe connected to the delivery tube. However, the rate of gas overflow varies depending on the hot spring environment, resulting in inconsistent collection speeds. When drawing gas from the collection bottle, insufficient gas intake leads to inadequate suction, while rapid gas collection causes excess gas to overflow. In practice, operators often visually assess the collected gas volume, which is labor-intensive and inaccurate, frequently resulting in insufficient gas to fill the syringe and collection bag.

[0004] Therefore, in view of the shortcomings of existing gas sampling devices that cannot provide timely and intuitive indication of the gas volume inside the gas sampling cylinder, this utility model discloses a hot spring gas sample collection device. Utility Model Content

[0005] This utility model discloses a hot spring gas sample collection device, which can provide timely and intuitive prompts to the operator once the gas volume inside the collection hood reaches the preset amount during the gas collection process, ensuring that the staff can deliver the gas after collecting the preset amount.

[0006] This utility model is achieved through the following technical solution: A hot spring gas sample collection device includes a collection hood, a suction syringe, and a gas collection bag. The collection hood is equipped with a liquid level indicator that can visually display the liquid level position inside the collection hood. A gas delivery pipe is provided on the top of the collection hood, and a three-way valve is provided on the gas delivery pipe. The first end of the three-way valve is connected to the collection hood, the second end of the three-way valve is connected to the suction syringe, and the third end of the three-way valve is connected to the gas collection bag.

[0007] The collection hood is used to collect gases overflowing from the hot spring. Submerging the hood below the water surface allows the hot spring water to expel the gas, enabling gas collection. Gas overflowing from the hot spring enters the collection hood, draining the hot spring water from top to bottom. At this point, the first end of the three-way valve is closed, and the collected gas remains inside the hood. As the gas gradually drains the hot spring water, the water level in the hood drops. When the liquid level indicator inside the hood reaches the set level, it visually alerts the operator that the set amount of gas has been collected. At this point, the first and second ends of the three-way valve can be opened, and the collected gas can be extracted using a suction syringe. The amount of gas extracted can be read from the scale on the suction syringe. Then, the first end of the three-way valve is closed, and the third end is opened, allowing gas to be introduced into the gas collection bag through the suction syringe, thus storing the gas in the gas collection bag.

[0008] To better realize this utility model, the liquid level indicator further includes a magnetic float, a magnetic switch, an indicator, and a power supply. The magnetic switch, indicator, and power supply constitute an indicator circuit. The magnetic switch is set at a predetermined height outside the collection hood, and the magnetic float is slidably set inside the collection hood.

[0009] To better realize this utility model, a vertical slide rail is further provided on the inner wall of the collection cover, and the magnetic float is slidably connected to the vertical slide rail.

[0010] To better realize this utility model, the indicator further includes an indicator light and / or an indicator buzzer.

[0011] To better realize this utility model, the top of the collection hood is provided with a first exhaust port and a second exhaust port. The first exhaust port is connected to the first end of the three-way valve through an air supply pipe, and the second exhaust port is connected to an exhaust hose with a shut-off clamp.

[0012] To better realize this utility model, a first quick connector is provided on the air supply pipe between the first exhaust port and the first end of the three-way valve, and the first quick connector is connected to a first venting hose with a shut-off clamp.

[0013] To better realize this utility model, a second quick connector is provided on the gas delivery pipe between the third end of the three-way valve and the gas collection bag, and the second quick connector is connected to a second venting hose with a shut-off clamp.

[0014] To better realize this utility model, the inlet of the gas collecting bag is further provided with a drying cylinder, and the inside of the drying cylinder is filled with desiccant.

[0015] To better realize this utility model, the lower end of the collection cover is further provided with an inverted conical collection hopper.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention features a liquid level indicator that floats with the liquid level inside the collection hood. When the collected gas discharges the liquid level inside the collection hood to a set level, it indicates that a preset amount of gas has been collected inside the collection hood. At this time, the liquid level indicator can provide timely visual prompts to the operator, ensuring that the operator can promptly deliver gas into the gas collection bag through the suction syringe.

Detailed Implementation

[0019] Example 1: This embodiment provides a hot spring gas sample collection device, such as... Figures 1-4 As shown, the device includes a collection hood 1, a suction syringe 2, and a gas collection bag 3. The collection hood 1 is equipped with a liquid level indicator 4, which can visually display the liquid level position inside the collection hood 1. The top of the collection hood 1 is equipped with a gas delivery pipe, and a three-way valve 5 is installed on the gas delivery pipe. The first end of the three-way valve 5 is connected to the collection hood 1, the second end of the three-way valve 5 is connected to the suction syringe 2, and the third end of the three-way valve 5 is connected to the gas collection bag 3.

[0020] The liquid level indicator 4 includes a floating part inside the collection hood 1 and a fixed part at a predetermined height outside the collection hood 1. The floating part and the fixed part can sense each other when they are close together to provide a visual indication. The collection hood 1 is submerged in spring water, filling it completely to expel any existing gas and prevent it from affecting the purity of subsequent hot spring gas collection. Gas from the hot spring overflows into the collection hood 1, discharging the hot spring water from top to bottom, thus collecting the hot spring gas. Simultaneously, as the hot spring water is expelled from the collection hood 1, the floating part floats with the liquid level to the position corresponding to the fixed part. At this point, the floating part and the fixed part sense each other to provide a visual indication, clearly and intuitively telling the operator that the gas inside the collection hood 1 has been collected to the predetermined volume. At this point, the first and second ends of the three-way valve 5 can be opened, and the gas inside the collection hood 1 can be extracted using the suction syringe 2. Then, the first end of the three-way valve 5 is closed, and the third end is opened, allowing the collected gas to be transported to the gas collection bag 3 for further collection using the suction syringe 2.

[0021] By setting up the liquid level indicator 4, the operator can be visually and intuitively informed that the amount of gas collected inside the collection hood 1 has reached the predetermined amount, which solves the problem that the operator needs to visually read the amount of gas inside the collection hood 1 in the traditional case.

[0022] Example 2: This embodiment discloses a hot spring gas sample collection device, which is an optimization based on Embodiment 1, such as... Figure 3 and Figure 4 As shown, the liquid level indicator 4 includes a magnetic float 41, a magnetic switch 42, an indicator 43, and a power supply 44. The magnetic switch 42, the indicator 43, and the power supply 44 constitute an indicator circuit. The magnetic switch 42 is set at a predetermined height outside the collection hood 1, and the magnetic float 41 is slidably disposed inside the collection hood 1.

[0023] The magnetic float 41 can float with the liquid level inside the collection hood 1. The more gas collected inside the collection hood 1, the lower the liquid level inside the collection hood 1 will be. When the magnetic float 41 floats to the height of the magnetic switch 42, the magnetic switch 42 closes under the magnetic force of the magnetic float 41, so that the magnetic switch 42, the indicator 43, and the power supply 44 form an indicator circuit and are connected. At this time, the indicator 43 is powered on to provide a visual prompt.

[0024] Furthermore, the magnetic switch 42, indicator 43, and power supply 44 are equipped with waterproof covers to prevent hot spring water from directly contacting the magnetic switch 42, indicator 43, and power supply 44.

[0025] Furthermore, a vertical slide rail 6 is provided on the inner wall of the collection hood 1, and the magnetic float 41 is slidably connected to the vertical slide rail 6. The magnetic float 41 includes a floating ring, a floating airbag at the bottom of the floating ring, a magnet at the top of the floating ring near the inner wall of the collection hood 1, and a groove on the outer surface of the floating ring that is slidably connected to the vertical slide rail 6. It should be further noted that the amount of air collected inside the collection hood 1 has been pre-calibrated and the volume of the vertical slide rail 6 and the magnetic float 41 has been subtracted.

[0026] Furthermore, the indicator 43 includes an indicator light and / or an indicator buzzer, which can provide visual and auditory cues.

[0027] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0028] Example 3: This embodiment discloses a hot spring gas sample collection device, which is optimized based on Embodiment 1 or 2, such as... Figure 2 As shown, the top of the collection hood 1 is provided with a first exhaust port 100 and a second exhaust port 200. The first exhaust port 100 is connected to the first end of the three-way valve 5 through an air supply pipe, and the second exhaust port 200 is connected to an exhaust hose 8 with a shut-off clamp.

[0029] Before immersing the collection hood 1 into the spring water, close the first vent 100 and open the shut-off clamp on the vent hose 8 at the second vent 200, allowing the second vent 200 to communicate with the external environment. Then, gradually immerse the collection hood 1 in the hot spring water, causing the hot spring water to force the original gas inside the collection hood 1 out through the second vent 200. Once the collection hood 1 is completely filled with hot spring water, close the shut-off clamp on the vent hose 8, and then the collection of hot spring water gas can begin.

[0030] Furthermore, a first quick-connector 101 is provided on the gas supply pipe between the first exhaust port 100 and the first end of the three-way valve 5, and the first quick-connector 101 is connected to a first venting hose 111 with a stop clamp. A second quick-connector 201 is provided on the gas supply pipe between the third end of the three-way valve 5 and the gas collecting bag 3, and the second quick-connector 201 is connected to a second venting hose 222 with a stop clamp. When a certain amount of gas is collected inside the collecting hood 1, the first end of the three-way valve 5 is kept closed, and after connecting the syringe to the first venting hose 111, the stop clamp is opened, and suction is performed through the syringe to extract the residual gas in the gas supply pipe from the first venting hose 111, so as to avoid the residual gas in the gas supply pipe affecting the purity of the finally collected hot spring gas. Similarly, before introducing gas into the gas collecting bag 3, keep the gas inlet of the gas collecting bag 3 closed, open the shut-off clamp on the second venting hose 222, and pump gas into the gas delivery tube using the suction syringe 2 to expel the residual gas in the gas delivery tube from the second venting hose 222, so as to avoid the residual gas in the gas delivery tube from affecting the purity of the hot spring gas finally collected.

[0031] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.

[0032] Example 4: This embodiment discloses a hot spring gas sample collection device, which is optimized based on any one of embodiments 1-3, such as... Figure 1 As shown, a drying cylinder 7 is provided at the inlet of the gas collecting bag 3, and the inside of the drying cylinder 7 is filled with desiccant. The inside of the drying cylinder 7 is filled with absorbent sponge and desiccant. After the hot spring gas is dried inside the drying cylinder 7, it enters the gas collecting bag 3 for collection.

[0033] The rest of the content of this embodiment is the same as any one of embodiments 1-3, so it will not be repeated here.

[0034] Example 5: This embodiment discloses a hot spring gas sample collection device, which is optimized based on any one of embodiments 1-4, such as... Figure 1 As shown, the lower end of the collection hood 1 is provided with an inverted conical collection hopper 9. The inner wall of the bottom end of the collection hood 1 is provided with an internal thread, and the top end of the collection hopper 9 is provided with an external thread, so that the collection hopper 9 is threadedly connected to the bottom of the collection hood 1. By setting the collection hopper 9, the gas collection area can be increased, so that more gas in the hot spring water can enter the collection hood 1 through the collection hopper 9, thereby improving the collection efficiency of hot spring gas.

[0035] The rest of the content of this embodiment is the same as any one of embodiments 1-4, so it will not be repeated here.
