Description
Technical Field
[0001] This application relates to the field of power well maintenance equipment technology, specifically to an intelligent working frame for power wellheads. Background Technology
[0002] With the development of society, the laying of power lines has become increasingly sophisticated. In suburban areas, power lines can be erected in the air via poles; however, in urban areas, most power lines are laid in underground power pipelines. To facilitate installation and maintenance, openable power manhole covers are installed at intervals to allow operators to go down into the manholes for repairs in case of a malfunction. Operators mostly use manhole work rigs to go down into the manholes to work.
[0003] The environment underground is extremely dangerous, containing various toxic gases and posing a risk of oxygen deficiency. Therefore, before going down into the well, it is necessary to vent the air from the surface into the well. Furthermore, operators often need to work underground for a long time at a time, so water may need to be replenished during the work. In addition, operators often use air guns and water guns, but if the diameter of the pipelines used to transport water and air is too large, it may cause insufficient pressure in the air chamber and water gun. Therefore, all of the above functions need to be achieved by setting up additional pipelines. The more pipelines there are, the more complex the structure becomes, and the more inconvenient the construction becomes.
[0004] Furthermore, to cope with emergencies, operators are required to carry self-rescue devices before entering the mine. These devices are portable respiratory protection equipment designed to prevent poisoning from harmful gases or suffocation due to lack of oxygen in the event of a fire, gas explosion, coal dust explosion, or coal and gas outburst underground. However, using them requires first removing the external canister, then pulling out the self-rescue device itself, putting on the headband, adjusting the air bag, then removing the mouthpiece plug, quickly activating the oxygen candle, and finally putting the mouthpiece in the mouth to breathe. The process is quite complex, and in an emergency, operators may panic and forget the steps. Moreover, self-rescue devices are emergency equipment with very low usage frequency; routine wear and inspection may make it difficult to detect potential problems in the early stages, and there is also the risk of accidental loss during use. Summary of the Invention
[0005] The purpose of this application is to provide an intelligent power wellhead work platform that facilitates downhole construction for operators, can respond to emergencies, and is easy to operate.
[0006] To achieve the above objectives, the technical solution adopted in this application is: an intelligent operating frame for power wellheads, characterized in that it includes a support structure, a ladder, a wind-driven device, and a water-driven device. The support structure is suitable for being erected on the wellhead. The ladder, the wind-driven device, and the water-driven device are all suitable for being installed on the support structure. The ladder is suitable for allowing operators to enter the wellhead, and the ladder is equipped with a main air channel and a main water channel. The top of the ladder is suitable for connecting to the wind-driven device and the water-driven device. The wind-driven device is suitable for filling the main air channel with air, and the water-driven device is suitable for filling the main air channel with water. The main waterway is located within the main waterway; and a controllable closure device is provided at the bottom of the ladder. The controllable closure device is adapted to control the opening and closing of the main airway and the bottom port of the main waterway. When the bottom port of the main airway is closed, the gas introduced into the main airway by the air source drive device and the water introduced into the main waterway by the water source drive device are adapted to remain in the main airway and the main waterway respectively, forming an air chamber and a water chamber. The controllable closure device is also provided with a water inlet and an air inlet respectively communicating with the main waterway and the main airway. An air outlet is also provided on the outer wall of the ladder, communicating with the main airway. The air outlet is adapted to controllably discharge the gas in the main airway.
[0007] The ladder described in this application not only serves as a tool for operators to descend into the well, but also features a main air channel and a main water channel, as well as a controllable closure at the bottom. When the controllable closure is open or closed, the air source drive device can introduce fresh air from the ground into the well through the ladder, effectively ensuring safety when breathing well air. The water source drive device can transport water downwards through the main water channel. When the controllable closure is closed, the main air channel and main water channel automatically form an air chamber and a water chamber and maintain this state. Operators can then use air guns and water guns through the air inlet and water inlet located on the controllable closure without the need for additional pipelines, thus increasing the ladder's functionality. The design is ingenious and the structure is novel. Furthermore, an air outlet connected to the main air channel is provided on the ladder. In an emergency, operators only need to open the air outlet to breathe fresh air. The structure is simple and the operation is convenient. Compared to using a self-rescue device, it saves many steps and improves the safety of operators to a certain extent. Furthermore, as an essential tool for operators to go down into the well, the ladder is highly practical for performing other functions. Moreover, the ladder is always with the operator, which also makes it convenient for the operator to quickly begin self-rescue in the event of an emergency.
[0008] As a preferred embodiment, the ladder comprises multiple assembly rods adapted to be connected end-to-end to form the ladder. Each assembly rod contains a second air passage and a second water passage, which are adapted to communicate when the assembly rods are connected, thus forming the main air passage and the main water passage. The controllable closure comprises a main body and an adjusting component. The main body contains a first air passage and a first water passage. The main body is adapted to be detachably connected to the bottom end of the ladder. When the main body and the bottom end of the ladder are connected, the first air passage is adapted to connect to the main air passage, and the first water passage is adapted to connect to the main water passage. The adjusting component is located at the bottom end of the main body and is adapted to control the opening and closing of the bottom ports of the first air passage and the first water passage. The above structure facilitates transportation and installation.
[0009] As another preferred embodiment, both the assembly rod and the main body have connectors at their top ends, the connectors being adapted to be threadedly connected to the bottom end of the assembly rod; the bottom end of the second air passage has a T-shaped cross-section and is adapted to be inserted into the top end of the second air passage or the first air passage within the connector and threadedly connected to the top end of the second air passage or the first air passage. This structure improves the freedom of installation and ensures the stability of the connection.
[0010] Further preferably, the controllable closure includes a main body and adjusting components. The main body has a first air passage and a first water passage inside. The main body is detachably connected to the bottom end of the ladder. When the main body and the bottom end of the ladder are connected, the first air passage is adapted to connect to the main air passage, and the first water passage is adapted to connect to the main water passage. The first air passage is located within the first water passage and is concentrically arranged with the first water passage. The adjusting component is located at the bottom end of the main body, and there are two adjusting components, each located on both sides of the bottom port of the first water passage. Each of the two adjusting components has an electromagnet at its inner end, and an elastic component is located between the two adjusting components. The two ends of the elastic component abut against the inner walls of symmetrically arranged receiving grooves on the two adjusting components. In the de-energized state, the elastic component is adapted to maintain a gap between the two adjusting components, thereby forming an open / closed state. In the energized state, the electromagnets are adapted to attract each other, compressing the elastic component until the two adjusting components abut against each other, thereby forming a closed state. The above structure is used to realize the opening and closing of the controllable closure.
[0011] Further preferably, the adjusting member is also equipped with a control device, a receiving device, and a mobile power source. The receiving device is adapted to receive signals and transmit the signals to the control device, and the control device is adapted to control the power supply and de-energization of the electromagnet by the mobile power source. This structure is used to achieve control of the controllable closure.
[0012] Further preferably, a thin film layer is provided outside the air outlet of the air head. In the absence of external force, the thin film layer is adapted to restrict the flow of gas from the air outlet in the main air passage. Applying force to the thin film layer is suitable for puncturing the thin film layer, allowing the gas in the main air passage to flow out from the air outlet. Both the water inlet and the air inlet are provided with valve bodies, which are adapted to control the opening and closing of the water inlet and the air inlet. The above structure is used to control the opening and closing of the air outlet, the water inlet, and the air inlet.
[0013] In a further preferred embodiment, the ladder is vertically oriented downwards and equipped with foot spikes. Each foot spike includes a crossbar and a limiting truncated cone. The crossbar is adapted to be fixedly connected to the ladder and is horizontally positioned, allowing the operator to step on it and hook hooks onto it. The limiting truncated cone is located at one end of the crossbar and is adapted to prevent the hooks from detaching. This structure facilitates the operator's entry into the well and provides a certain degree of protection.
[0014] Further preferably, the support structure includes a load-bearing rod, a support rod, and a mounting plate. The support rod is adapted to be installed at the edge of the wellhead, and both the load-bearing rod and the mounting plate are adapted to be arranged laterally above the wellhead.
[0015] Further preferably, the support rods are four in number, with each pair of support rods forming a group. Two groups of support rods are symmetrically arranged on both sides of the wellhead. The top ends of the two support rods in a group are rotatably connected, and each support rod has a base rotatably connected to its bottom end. The base has a positioning hole for connecting to the ground. The support structure also includes a fixing rod and a clamp. The fixing rod is located between the support rods and is adapted to limit the relative displacement between them. The mounting plate is adapted to be installed between the fixing rods. The two ends of the load-bearing rod are adapted to pass through a group of support rods respectively. The clamp is adapted to limit the relative movement between the load-bearing rod and the support rod, or between the fixing rod and the support rod. The mounting plate is adapted to install the air source drive device and the water source drive device, as well as the main control box, main power supply, and detector. The load-bearing rod is adapted to mount a fall arrestor. This structure facilitates transportation and installation, is structurally stable, and makes efficient use of space.
[0016] Further preferably, a connector is fixedly provided on the ladder, and the connector has an assembly groove adapted to the support structure, so that the connector is suitable for hanging on the support structure, and the inner wall of the assembly groove abuts against the outer wall of the support structure, so that the assembly groove and the support structure cooperate to restrict the rotation of the ladder. The above structure is used to connect the ladder and the support structure.
[0017] Compared with the prior art, the beneficial effects of this application are as follows:
[0018] This application employs a technical means of setting up a main air duct and a main water duct inside the ladder, and setting a controllable closure device at the bottom of the ladder. After the ladder is connected to the air source drive device and the water source drive device, when the controllable closure device is in the open or closed state, the air source drive device can introduce air into the well through the main air duct, and the water source drive device can transport water downward through the main water duct. When the controllable closure device is set to the closed state, the main air duct and the main water duct automatically form an air chamber and a water chamber and maintain this state. The operator can use the air gun and water gun through the air inlet and water inlet set on the controllable closure device without setting up other pipelines. In the event of an emergency, the operator can open the air outlet to breathe fresh air. Thus, the ladder can not only be used as a tool for going down into the well, but also as a tool for ventilation before going down into the well, transporting water, connecting air guns and water guns, and self-rescue in the event of an emergency. It increases the functionality of the ladder, is ingeniously designed, has a simple and novel structure, and is easy to operate. Attached Figure Description

[0036] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0037] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0038] like Figures 1-14 As shown, the preferred embodiment of this application is as follows:
[0039] The system includes a support structure 1, a ladder 2, an air-driven device 3, and a water-driven device 10. The support structure 1 is suitable for being erected on the wellhead. The ladder 2, air-driven device 3, and water-driven device 10 are all suitable for being installed on the support structure 1. The ladder 2 is suitable for allowing operators to enter the wellhead, and the ladder 2 is equipped with a main air passage and a main water passage. The top of the ladder 2 is suitable for connecting to the air-driven device 3 and the water-driven device 10. The air-driven device 3 is suitable for filling the main air passage with air, and the water-driven device 10 is suitable for filling the main water passage with water. The bottom of the ladder 2 is equipped with a controllable closure device 4 for controllable closure. Device 4 is suitable for controlling the opening and closing of the bottom port of the main air duct and the main water duct. When the bottom port of the main air duct is closed, the gas filled into the main air duct by the air source drive device 3 and the water filled into the main water duct by the water source drive device 10 are suitable for being stored in the main air duct and the main water duct respectively, forming an air chamber and a water chamber. The controllable sealing device 4 is also provided with a water inlet 45 and an air inlet 46 that are respectively connected to the main water duct and the main air duct. The water inlet 45 is suitable for connecting a water gun, and the air inlet 46 is suitable for connecting an air gun. The outer wall of the ladder 2 is also provided with an air outlet 212 that is connected to the main air duct. The air outlet 212 is suitable for controllably discharging the gas in the main air duct.
[0040] Unlike traditional technical solutions, the ladder 2 in this application not only serves as a tool for operators to go down into the well, but also has a main air channel and a main water channel inside, as well as a controllable closure device 4 at the bottom. When the controllable closure device 4 is open or closed, the air source drive device 3 can introduce fresh air from the ground into the well through the ladder 2, thereby effectively ensuring safety when breathing the air in the well. The water source drive device 10 can transport water downward through the main water channel. When the controllable closure device 4 is set to the closed state, the main air channel and the main water channel automatically form an air chamber and a water chamber and maintain this state. Operators can use air guns and water guns through the air inlet 46 and water inlet 45 set on the controllable closure device 4. By setting the diameter of the air inlet 46 and water inlet 45 to a small diameter, the high pressure requirements of the air gun and water gun can be met without the need for other pipelines. This increases the functionality of the ladder 2, and the design is ingenious and the structure is novel. Furthermore, an air outlet 212 connected to the main air duct is installed on ladder 2. In an emergency, the operator only needs to open the air outlet 212 to breathe fresh air. The structure is simple and easy to operate, saving many steps compared to using a self-rescue device and improving operator safety to a certain extent. As an essential tool for operators going down the well, ladder 2 is highly practical for performing other functions, and since it is always near the operator, it allows for quick self-rescue in emergency situations.
[0041] Furthermore, to facilitate the transportation of the support structure 1 of this application and to provide a sufficient carrier for installing other devices, in this embodiment, the support structure 1 includes a load-bearing rod 11, a support rod 12, and a mounting plate 14. The support rod 12 is adapted to be detachably installed at the edge of the wellhead. The load-bearing rod 11 and the mounting plate 14 are both adapted to be detachably arranged horizontally above the wellhead, and both the load-bearing rod 11 and the mounting plate 14 are adapted to connect external devices.
[0042] In this embodiment, the support structure 1 consists of a load-bearing rod 11, a support rod 12, and a mounting plate 14. The support rod 12 is detachably connected to the ground, and the connections between the support rod 12, the load-bearing rod 11, and the mounting plate 14 are also detachable. In other words, the entire support structure 1 is detachable, allowing it to be disassembled for carrying. This reduces space requirements and makes it more convenient to carry. Furthermore, the load-bearing rod 11 and the mounting plate 14 are arranged between the support rods 12. Devices requiring attachment, such as a fall arrestor 6, can be attached to the load-bearing rod 11. Devices such as a main control box 7, a main power supply 8, a detector 9, a water-driven device 10, and a wind-driven device 3 can be mounted on the mounting plate 14. This makes the support structure 1 more versatile and more convenient for operators.
[0043] Furthermore, as a wellhead working frame, the stability of the support structure 1 is particularly important. Therefore, in this embodiment, there are multiple support rods 12, which are suitable for being evenly arranged in multiple groups around the wellhead. Specifically, there are four support rods 12, and each pair of support rods 12 forms a group. The two groups of support rods 12 are symmetrically arranged on both sides of the wellhead. The support rods 12 are provided with assembly holes 121, and one end of the load-bearing rod 11 is suitable for passing through the assembly holes 121 on the two support rods 12 in a group, so that the two support rods 12 are suitable for rotating around the load-bearing rod 11. In addition, a base 13 is rotatably connected to the bottom end of the support rod 12, and the base 13 is provided with positioning holes 131 for connecting to the ground.
[0044] Therefore, in this embodiment, the load-bearing rod 11 serves as the central axis connecting the two support rods 12, and the support rods 12 are divided into two groups, symmetrically arranged on both sides of the load-bearing rod 11. The structure is simple and stable. The two support rods 12, which are rotatably connected, can rotate freely during installation to adjust the height of the load-bearing rod 11. After the position is determined, it can be connected to the bottom surface through the positioning hole 131 on the base 13, thereby reliably ensuring the stability of the overall support structure 1. In addition, the base 13 and the support rods 12 are rotatably connected, so no matter how the support rods 12 rotate, the base 13 can rotate to be parallel to the bottom surface, that is, the bottom end surface is completely in contact with the ground.
[0045] Furthermore, to increase the stability of the support structure 1, in this embodiment, a fixing rod 15 is provided between the support rods 12, and the fixing rod 15 is adapted to limit the relative displacement between the support rods 12.
[0046] Furthermore, in this implementation, such as Figure 3 As shown, the support structure 1 also includes a clamp 16, which is adapted to restrict the relative movement between the load-bearing rod 11 and the support rod 12, or between the fixed rod 15 and the support rod 12. The clamp 16 includes a connecting seat 161, a rotation limiting member 162, and an adjusting bolt 163. Both the rotation limiting member 162 and the connecting seat 161 have corresponding arch-shaped structures to form a connection port 164 between them. One end of the rotation limiting member 162 is rotatably connected to the connecting seat 161, and the other end of the rotation limiting member 162 and the connecting seat 161 are provided with an adjusting bolt 163. The rotation limiting member 162 has a limiting hole 1621, and the adjusting bolt 163 is adapted to pass through the limiting hole 1621 and connect to the connecting seat 161 so that the adjusting bolt 163 is adapted to adjust the size of the connection port 164. The above structure is used for other rod-like parts to pass through the clamp 16, and the clamp 16 is secured to other rod-like parts by adjusting the bolt 163.
[0047] Furthermore, the limiting hole 1621 on the rotating limiting member 162 for the adjusting bolt 163 to pass through has an opening on the side wall of the rotating limiting member 162, and the adjusting bolt 163 is rotatably connected to the connecting seat 161, so that the adjusting bolt 163 can rotate in and out of the limiting hole 1621; and the connecting seat 161 is also provided with a connecting hole 1611. The above structure facilitates the connection of the clamp 16 with other parts.
[0048] like Figure 3 As shown, in this embodiment, a clamp 16 is provided on both sides of the connection where the load-bearing rod 11 passes through the support rod 12. The support rod 12 is clamped by the two clamps 16, and the size of the connection opening 164 is reduced by adjusting the bolt 163, so that the clamp 16 can be clamped on the load-bearing rod 11. Therefore, the axial movement of the support rod 12 can be restricted, thereby improving the stability of the connection between the support rod 12 and the load-bearing rod 11.
[0049] like Figure 4 As shown, in this embodiment, since the connecting seat 161 is provided with a connecting hole 1611, the clamp 16 can be installed on the fixing rod 15 by bolts, and then the clamp 16 can be clamped on the support rod 12 by adjusting the bolt 163, thereby achieving a stable connection between the fixing rod 15 and the support rod 12.
[0050] By ensuring a stable connection between the load-bearing rod 11 and the fixed rod 15, other devices can be installed on them. In this embodiment, the mounting plate 14 is suitable for installing the air source drive device 3 and the water source drive device 10, as well as the main control box 7, the main power supply 8, and the detector 9. The load-bearing rod 11 is suitable for mounting the fall arrestor 6. The above-mentioned devices are used to increase the functionality of the imported work frame of this application. For example, the air source drive device 3 can discharge fresh air into the well or draw air up from the well, and then detect it through the detector 9 to determine whether to go down into the well. The fall arrestor 6 can effectively deal with the situation where the operator accidentally falls, increasing the safety of the operator. The main control box 7 can control the operation of the air source drive device 3 and the detector 9 to achieve intelligent operation. In addition, other devices such as alarms, detection and sensing devices can also be installed on the mounting plate 14. All of them can be powered by the main power supply 8 and controlled by the main control box 7 to make the application highly intelligent.
[0051] Furthermore, to further enhance portability, ladder 2 is also a detachable structure, specifically as follows: Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, in this embodiment, the ladder 2 includes multiple assembly rods 21, which are adapted to be connected end to end to form the ladder 2. Each assembly rod 21 is provided with a second air passage 211 and a second water passage 213. The second air passage 211 and the second water passage 213 are adapted to communicate when the assembly rods 21 are connected, thereby forming a main air passage and a main water passage. The controllable closure 4 includes a main body 41 and an adjusting member 42. The main body 41 is provided with a first air passage 411 and a first water passage 412. The main body 41 is adapted to be detachably connected to the bottom end of the ladder 2. When the main body 41 and the bottom end of the ladder 2 are connected, the first air passage 411 is adapted to be connected to the main air passage, and the first water passage 412 is adapted to be connected to the main water passage. The adjusting member 42 is provided at the bottom end of the main body 41 and is adapted to control the opening and closing of the bottom ports of the first air passage 411 and the first water passage 412. The above structure, under the premise of achieving normal ventilation and drainage, divides the ladder 2 into multiple detachable and assembleable assembly rods 21, which are easy to carry, and the controllable closure 4 is also detachably connected to the ladder 2.
[0052] Furthermore, such as Figure 8 As shown, in this embodiment, both the top of the assembly rod 21 and the main body 41 are provided with a connector 5, which is suitable for threaded connection with the bottom end of the assembly rod 21; the cross-section of the bottom end of the second air passage 211 is T-shaped and is suitable for insertion into the top end of the second air passage 211 or the first air passage 411 within the connector 5 and threaded connection with the top end of the second air passage 211 or the first air passage 411. The above structure allows the assembly rod 21 to be assembled arbitrarily, so that the ladder 2 can change its length according to the depth of the well during operation, increasing the practicality of the ladder 2. Furthermore, the controllable seal 4 has connectors 5 of the same specifications, so that the controllable seal 4 can be connected to any assembly rod 21, which is more flexible. When the connector 5 is connected to the bottom end of the assembly rod 21, the two internal air passages are also threadedly connected, which provides better stability and airtightness compared to direct docking.
[0053] In addition, such as Figures 9-13As shown, in this embodiment, the controllable closure 4 includes a main body 41 and an adjusting member 42. The main body 41 has a first air passage 411 and a first water passage 412 inside. The main body 41 is adapted to be detachably connected to the bottom end of the ladder 2. When the main body 41 and the bottom end of the ladder 2 are connected, the first air passage 411 is adapted to connect to the main air passage, and the first water passage 412 is adapted to connect to the main water passage. The first air passage 411 is located inside the first water passage 412 and is concentrically arranged with the first water passage 412. The adjusting member 42 is located at the bottom end of the main body 41 and has two... Two adjusting members 42 are respectively located on both sides of the bottom port of the first air passage 411. Each adjusting member 42 has an electromagnet 422 at its inner end, and an elastic member 43 is provided between the two adjusting members 42. The two ends of the elastic member 43 abut against the inner wall of the symmetrically arranged receiving groove 421 on the two adjusting members 42. In the de-energized state, the elastic member 43 is adapted to keep the two adjusting members 42 separated by a gap, thereby forming an open and closed state. In the energized state, the electromagnets 422 are adapted to attract each other, so as to compress the elastic member 43 until the two adjusting members 42 abut against each other, thereby forming a closed state.
[0054] In this embodiment, the elastic element 43 is a spring because springs are low in manufacturing cost and have a simple and stable structure. A protrusion is provided in the receiving groove 421 to connect the spring. In addition, the reason for providing the receiving groove 421 is that when the electromagnets 422 attract each other in the energized state, the two adjusting elements 42 will move closer to each other and the spring can be completely compressed in the receiving groove 421, so that the two adjusting elements 42 can be tightly fitted, thereby reliably ensuring the effect of closing the bottom port of the first air passage 411.
[0055] Furthermore, the adjusting component 42 is also equipped with a control box 44, which contains a control device, a receiving device, and a mobile power supply. The receiving device is adapted to receive signals and transmit them to the control device, and the control device is adapted to control the power supply and de-energization of the electromagnet 422 by the mobile power supply. The above structure enables remote control. Before going down into the well, no signal is sent, which means it is in a power-off state. At this time, the air blown by the air source drive device 3 is directly blown into the well through the main air duct and the first air duct 411, thereby reducing the danger of breathing down into the well. In addition, the water source drive device 10 can transport water to the well through the main water duct and the first water duct 412. Furthermore, a signal can be sent to the receiving device through the main control box 7 or other transmitting devices to enter the power-on state, which is quite convenient. It is worth mentioning that the structure and function of the various electrical components in the control device and the receiving device are common knowledge in the art and are not the inventive point of this application. Therefore, this application will not describe them in detail, but this does not prevent them from being implicit technical features of this application.
[0056] It is worth mentioning that, to further enhance intelligence, launching devices can be installed on the air gun and water gun. When the operator is working normally underground, the controllable closure 4 is in the open / closed state, and the air source drive device 3 keeps blowing air down into the well, effectively ensuring the safety of the operator. The operator can control the switch of the water source drive device 10 through the launching device. When water needs to be added or used, the water source drive device 10 can be turned on. When the operator needs to use the air gun and water gun, he only needs to use the launching device to control the controllable closure 4 to close. At this time, the large pipeline used for transportation is closed, and the operator can use the air gun and water gun under the pressure conditions through the small-diameter air inlet 46 and water inlet 45 set on the controllable closure 4 to complete the work.
[0057] Furthermore, a sensing device can be installed in the work frame of this application. Since a certain period of venting and measurement is often carried out before going down into the well, the air quality down in the well is relatively safe. Therefore, the sensing device can be set to automatically control the controllable closure 4 to close when it senses that the operator is going down into the well, thereby turning the main air passage into an air chamber. The operator can breathe fresh air through the air outlet 212 at any time, thus being prepared for emergencies. When it senses that the operator has reached the working position down in the well, it will automatically control the controllable closure 4 to open, continue to vent air down into the well, and the sensing device can detect the operator's physical information in real time. Once it detects that the operator may be in a critical situation, it will control the controllable closure 4 to close and issue an alarm.
[0058] After the air chamber inside the assembly rod 21 is formed, in order to prevent gas leakage and to allow the air outlet 212 to be opened in an emergency, in this embodiment, a thin film layer 214 is provided outside the air outlet of the air outlet 212. In the absence of external force, the thin film layer 214 is adapted to restrict the gas in the main airway from flowing out of the air outlet. Applying force to the thin film layer 214 is adapted to puncture the thin film layer 214 so that the gas in the main airway can flow out of the air outlet.
[0059] In some embodiments, the vent 212 is provided with a switch, which is adapted to adjust the opening and closing of the vent 212. The switch can be a push-button type or a rotary type, but since the vent 212 is used in emergency situations, simplicity is particularly important. Therefore, compared with using a switch to control the vent 212, the thin film layer 214 in this embodiment is simpler, and can be opened by simply poking it with a finger.
[0060] It is worth mentioning that, in order to ensure the stability of air pressure, a pressure reducing valve can also be installed on the air outlet 212. In order to reduce the possibility of damage to the membrane layer 214 during daily use, the membrane layer 214 can be placed slightly inside the air port on the air outlet 212, or a cover can be installed outside the air port. The connection between the cover and the air port should be made in a way that is easy to open, such as a slight interference fit. The air outlet 212 is positioned between the two foot spikes 23. In actual work, the operator steps down on the foot spikes 23 and hangs the hook on the foot spike 23 above the one being stepped on. Therefore, the face of the operator is roughly between the two foot spikes 23. Therefore, the air outlet 212 is positioned in this way to facilitate the operator's self-rescue.
[0061] Furthermore, since air guns and water guns are often used repeatedly, and it is necessary to ensure the airtightness of the main air and water channels when transporting gas and water, in this embodiment, valve bodies are provided on both the water inlet 45 and the air inlet 46. These valve bodies are suitable for controlling the opening and closing of the water inlet 45 and the air inlet 46. This structure facilitates operator control of the water inlet 45 and the air inlet 46 and allows for repeated use.
[0062] Furthermore, to ensure that operators can access the underground well via ladder 2, in this embodiment, ladder 2 is vertically downward and equipped with foot spikes 23. Each foot spike 23 includes a crossbar 231 and a limiting frustum 232. The crossbar 231 is horizontally positioned and fixedly connected to ladder 2, allowing operators to step on it and hang hooks on it. The limiting frustum 232 is located at one end of the crossbar 231 and prevents hooks from falling off. In this embodiment, the foot spikes 23 and assembly rod 21 are primarily connected by threads, allowing the foot spikes 23 to pass through the assembly rod 21 and be connected with a nut. Therefore, the foot spikes 23 will pass through the main air and water channels. The threaded connection may not provide sufficient sealing, potentially leading to air and water leakage. Therefore, thread sealant can be applied to the threads between the foot spikes 23 and the assembly rod 21 to ensure a tight seal after connection.
[0063] Furthermore, to ensure ease of connection between the ladder 2 and the support structure 1, such as... Figure 1 and Figure 13As shown, in this embodiment, a connector 22 is fixedly provided on the ladder 2. The connector 22 has an assembly groove 221 that is adapted to the support structure 1, so that the connector 22 is suitable for hanging on the support structure 1. The inner wall of the assembly groove 221 abuts against the outer wall of the support structure 1, so that the assembly groove 221 and the support structure 1 cooperate to restrict the rotation of the ladder 2. The above structure is easy to operate, and the above-mentioned adaptation refers to the fact that the shape of a certain part in the support structure 1 is adapted to the assembly groove 221. Both the shape of the part and the assembly groove 221 are square, rectangular, or similar shapes, so that the inner wall of the assembly groove 221 can abut against the outer wall of the part, thereby restricting the rotation of the ladder 2.
[0064] In addition, such as Figure 14 As shown, in this embodiment, a platform 24 can also be fixedly sleeved on the assembly rod 21. When the operator is working underground, he / she can temporarily place tools on the platform 24, which can facilitate the work of the personnel going down into the well.

Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
