Description

Technical Field

[0001] The present invention belongs to the field of gas collection technology, and specifically is a water surface escape gas collection device compatible with multiple scenarios. Background Art

[0002] Currently, global warming is one of the major environmental challenges facing humanity, and the increase in greenhouse gas concentrations in the atmosphere is considered a key factor in global warming. Wetlands, agriculture, and reservoirs, as important sources of greenhouse gas emissions, have received widespread attention. In the field of agricultural production, aquaculture is a typical agricultural production activity. During its production process, a variety of gases will escape from the water surface. These gases may contain greenhouse gas components that have a significant impact on climate change. Accurately collecting and analyzing these gases escaping from the water surface is of great significance for in-depth understanding of the greenhouse gas emission mechanism, quantifying emissions, and formulating effective emission reduction strategies. Therefore, a device for collecting gases escaping from the water surface is urgently needed.

[0003] Existing surface gas collection devices often have limitations when in use. For example, they have poor adaptability in complex water environments and are difficult to meet the requirements of multi-scenario compatibility. Some devices have complex architectures, which not only increases costs but also may lead to inconvenience in operation and difficulty in maintenance. Moreover, during the collection process, the accuracy and efficiency of gas collection may be affected by the device's own structure or external factors. For example, some closed-structure collection devices may inhibit the ability of surface gas to escape, while some collection devices lack targeted collection solutions when dealing with different working conditions (such as whether the water area has an aeration device). They are not flexible in fixing and positioning, making it difficult to meet the needs of scientific research projects requiring fixed-point, continuous monitoring. Summary of the Invention

[0004] In response to the above-mentioned problems, the present invention provides a water surface escape gas collection device that is compatible with multiple scenarios.

[0005] The technical solution of the present invention is: a multi-scenario compatible water surface escape gas collection device, comprising a floating plate, a collection body connected to the upper end of the floating plate, a fixed containment component connected to the collection body, and a gas collection and detection component;

[0006] The collection body is provided with a collection cover with an open structure at the upper end, the upper end of the collection cover is provided with a box plug, and the box plug is provided with a gas one-way valve, a gas collection hole and a reserved hole;

[0007] The fixed containment assembly includes a collar provided on the side wall of the collection body, a fixed support frame fixed to the ground, and a fixed connecting pipe for connecting the fixed support frame and the collar;

[0008] The gas collection and detection component includes a gas collection pipe with one end extending into the collection body through the gas collection hole, a gas filter connected to one end of the gas collection pipe located outside the collection body, an automatic gas collection cylinder connected to the gas filter and provided with a solenoid valve at the connection, a connecting wire extending into the collection body through a reserved hole, a module sensor component connected to one end of the connecting wire located inside the collection body, and a single-light column digital display measurement and control instrument connected to the module sensor component through the connecting wire. A plurality of air inlet holes are evenly arranged on the side wall of the gas collection pipe located inside the collection body.

[0009] Furthermore, a through mounting opening is provided at the center of the floating plate, and each inner wall of the through mounting opening is provided with a sliding groove with a T-shaped cross-section, and the side wall of the collection body is provided with a sliding buffer bar that corresponds to and is slidably connected to the sliding groove. The sliding buffer bar includes a T-shaped sliding block that can slide in the sliding groove, a spring buffer column provided on the left and right sides of the horizontal section of the T-shaped sliding block, and a limit column connected to the spring buffer column, and the end of the limit column is provided with a wear-resistant head.

[0010] Description: When the collecting body is connected to the through-mounting port at the center of the floating plate, the sliding buffer strips on the side walls of the collecting body are placed one by one in the sliding grooves and slide downward along the sliding grooves until the bottom end of the collecting body contacts the bottom end of the through-mounting port, thereby completing the installation of the collecting body and the floating plate. The cooperation between the sliding grooves and the sliding buffer strips can limit the collecting body in all directions, which can enhance the connection firmness between the collecting body and the floating plate. When the sliding buffer strips slide downward along the sliding grooves, they are mainly limited by the T-shaped sliding blocks. The spring buffer columns on the left and right sides of the horizontal section of the T-shaped sliding block and the limit columns connected to the spring buffer columns serve to buffer the force at the connection between the collecting body and the floating plate, reduce the direct friction and collision between the collecting body and the floating plate at the connection, which helps to reduce the wear of the T-shaped sliding blocks, sliding grooves and other related components, and because a wear-resistant head is provided at the end of the limit column, the wear of the limit column can be further reduced, thereby ensuring the overall service life of the device.

[0011] Furthermore, an inflatable floating airbag is provided on the outer wall of the floating plate, and a sealing jacket is attached to the outer wall of the collection body.

[0012] Note: An inflatable floating airbag is installed on the outer wall of the float to increase the buoyancy of the float, prevent the collection body from tipping over when the water flow is turbulent, and ensure the normal progress of the gas collection operation. A sealing jacket is attached to the outer wall of the collection body to increase the sealing of the connection between the collection body and the float, ensuring that the gas collection process is not interfered with by external gases.

[0013] Furthermore, a reflective heat absorbing plate is provided on the outer wall of the receiving cover, and the reflective heat absorbing plate is composed of multiple reflective plates and multiple heat absorbing plates that are staggered and spliced ​​together, and multiple reflective columns are evenly arranged on the reflective plate, and a ceramic fiber insulation layer is attached to the outer wall of the heat absorbing plate.

[0014] Description: A reflective heat-absorbing plate is set on the outer wall of the collection cover to absorb and reflect external light, reducing the impact of direct sunlight on the gas exchange at the water-air interface in the collection body. When the reflective heat-absorbing plate is in use, several reflective plates and several heat-absorbing plates are staggered. The reflective plates can reflect the direct light and absorb the heat of the sunlight through the heat-absorbing plates to avoid the influence of external light on the gas collection work. The heat-absorbing plates can also absorb the light reflected by the adjacent reflective plates for a second time, further reducing the impact of external ambient temperature and pressure fluctuations on the gas collection effect.

[0015] Furthermore, the fixed support frame is composed of two connecting platforms with stable support legs at the bottom ends, which are distributed relatively. One of the connecting platforms has a mounting box on its side wall, and a torsion spring is provided inside the mounting box. The other connecting platform has a fixing ring on its side wall opposite to the mounting box. A connecting rope lock connected to the fixing ring is connected to the torsion spring, and an adjusting clamping sleeve is provided on the connecting rope lock. The bottom end of the adjusting clamping sleeve is connected to the fixed connecting pipe.

[0016] Description: When the fixed support frame is in use, the connecting platform with the installation box installed is fixed to the shore of the gas collection water area by the stabilizing legs. Then, another connecting platform is pulled. At this time, under the action of the torsion spring, the connecting rope lock gradually winds out of the installation box and stretches. When the connecting rope lock is stretched to the position where the other connecting platform needs to be installed, it is fixed by the stabilizing legs at the bottom end of the connecting platform. At this time, the adjusting clamping sleeve is fixed on the connecting rope lock, and the connection between the bottom end of the clamping sleeve and the fixed connecting pipe and the fixed connecting pipe and the collar is adjusted to make the collection body float on the water surface. When the position of the collection body needs to be moved, it is only necessary to change the position of the adjusting clamping sleeve on the connecting rope lock. Since the connecting rope lock can be stretched under the action of the torsion spring, it can adapt to the installation requirements of the shore at different distances. At the same time, when the position of the collection body needs to be moved, there is no need to dismantle and reinstall the entire fixed support frame on a large scale, saving time and labor costs, and being able to quickly meet different collection requirements.

[0017] Furthermore, the adjustment clamping sleeve is composed of two sub-clamping sleeves that are rotatably connected at the bottom ends, and the upper ends of the two sub-clamping sleeves are connected by a snap buckle. The inner wall of each sub-clamping sleeve is provided with a movable notch, and the sub-clamping sleeve is provided with a fixed clamping plate that matches the size of the movable notch and has fixed teeth on the inner wall. A screw rod that penetrates to the outside of the sub-clamping sleeve is provided on the side of the fixed clamping plate opposite to the fixed teeth.

[0018] Description: When installing the adjusting clamping sleeve, clamp the two sub-clamping sleeves on the outer wall of the connecting rope lock and fix them with buckles. At this time, in order to increase the reliability of the clamping between the sub-clamping sleeves and the connecting rope lock, screw the screw rods on each sub-clamping sleeve to clamp the fixed clamping plate and the connecting rope lock. At the same time, each fixing tooth tightens and fixes the connecting rope lock at multiple points, fixing the connecting rope lock clamp from multiple angles, which greatly increases the firmness of the connection between the adjusting clamping sleeve and the connecting rope lock.

[0019] Furthermore, the bottom end of the stabilizing leg is provided with support feet distributed in a divergent shape.

[0020] Note: Support feet distributed in a divergent shape are set at the bottom of the stabilizing legs to increase the installation stability of the stabilizing legs and the bottom of the connecting platform, and further improve the working reliability of the gas collection device.

[0021] Furthermore, the module sensing component includes a pressure sensor for real-time monitoring of air pressure changes, an electronic flow meter for real-time monitoring of gas flow, and a gas composition analysis sensor for comprehensive monitoring of the physical and chemical properties of the collected gas.

[0022] Description: Install the module sensor component in the collection body and connect it to the single-light-bar digital display measurement and control instrument through connecting wires. It can not only monitor the air pressure changes in the collection body in real time, monitor the gas flow in real time, and comprehensively monitor the physical and chemical properties of the collected gas, but also help to gain a deeper understanding of the collected gas situation, provide rich data support for subsequent research or applications, and transmit the detection results to the single-light-bar digital display measurement and control instrument. The single-light-bar digital display measurement and control instrument can display the data such as the air pressure changes, gas flow, and physical and chemical properties of the gas in the collection body detected by the module sensor component in an intuitive form, which is convenient for subsequent analysis and research.

[0023] Furthermore, it also includes a gas storage box with a door on the side wall, the upper end of the gas storage box is connected to the gas outlet end of the automatic gas collection cylinder and an automatic opening and closing valve is provided at the connection, a partition plate is provided in the gas storage box, a plurality of puncture tubes are provided at the bottom end of the partition plate, the bottom end of the gas storage box is connected to a supporting tray through a hydraulic cylinder, the supporting tray is provided with placement grooves corresponding to the puncture tubes, each of the placement grooves is placed on a temporary storage tube, and a rubber sealing plug is installed at the opening of the upper end of the temporary storage tube.

[0024] Description: Open the automatic opening and closing valve, and the gas collected by the automatic gas collection cylinder enters the upper end of the gas storage box. At this time, the extension action of the hydraulic cylinder drives the supporting tray to move upward until each temporary storage cylinder contacts the bottom end of the puncture tube and punctures the rubber sealing plug at the upper end of the temporary storage cylinder. The gas at the upper end of the gas storage box enters each temporary storage cylinder in batches through the puncture tube for standby. After the collection is completed, close the automatic opening and closing valve, and the compression action of the hydraulic cylinder drives the supporting tray to move downward to separate the puncture tube from each temporary storage cylinder. The box door is opened, and each temporary storage cylinder filled with collected gas is taken out. Then, empty temporary storage cylinders are placed in each placement slot again, and the above gas storage process is repeated. In the above process, gas can enter each temporary storage cylinder in batches through the puncture tube for standby. This batch storage method can collect and store a large amount of gas in a shorter time. For situations where a large amount of gas samples need to be collected, this method can improve the efficiency of collection and storage and save time.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) When a multi-scenario compatible surface gas collection device of the present invention is used, a collecting mask is provided at the upper end of the collection body, so that the collection body as a whole has a structure that is wide at the bottom and narrow at the top. At the same time, a collecting mask with an open structure at the upper end is provided on the collection body. When an aeration device is provided, it helps the outer wind body to form a vortex, and will not flow back into the collection body through the opening structure, effectively avoiding the inhibition of the surface gas escape ability. At the same time, the present invention provides a highly targeted and feasible gas collection solution through different working conditions of the water area to be collected. That is, when the water area to be collected is not installed with an aeration device, the gas collection time of the automatic gas collection cylinder is controlled, and the gas is collected in a gradient manner during the collection period to capture the gas concentration change characteristics in different time periods. When the water area to be collected is installed with an aeration device, the time required for the original gas in the collection body to be discharged is calculated based on the data obtained by the module sensor component and the known parameters. After the time is reached, the gas collection process is immediately started, providing accurate and efficient technical support and method guidance;

[0027] (2) The present invention fixes the collection body on the water surface at a specific location through a fixed restraining component, and maintains the collection body stable on the water surface through the relative installation of two connecting platforms, which facilitates the accurate collection of escaped gas in the target area and provides reliable protection for scientific research projects that require fixed-point and continuous monitoring. When the position of the collection body needs to be moved, it is only necessary to change the position of the adjusting clamping sleeve on the connecting rope lock, without the need for large-scale disassembly and reinstallation of the entire fixed support frame, thus saving time and labor costs and being able to quickly meet different collection needs;

[0028] (3) The present invention can absorb and reflect external light by arranging a reflective heat-absorbing plate on the outer wall of the collection cover, thereby reducing the influence of direct sunlight on the gas exchange at the water-air interface in the collection body. When the reflective heat-absorbing plate is in use, a plurality of reflective plates and a plurality of heat-absorbing plates are staggered and distributed. The reflective plates can reflect the directly incident light and absorb the heat of the sunlight through the heat-absorbing plates, thereby avoiding the influence of external light on the gas collection work. The heat-absorbing plates can also absorb the light reflected by the adjacent reflective plates for a second time, thereby further reducing the influence of the external ambient temperature and air pressure fluctuations on the gas collection effect.

[0029] (4) The present invention sets up a gas storage box, and the gas collected by the automatic gas collection cylinder enters the upper end of the gas storage box, and contacts the bottom end of the puncture tube through each temporary storage tube and punctures the rubber sealing plug at the upper end of the temporary storage tube. The gas at the upper end of the gas storage box enters each temporary storage tube in batches through the puncture tube for standby. After the collection is completed, the puncture tube is separated from each temporary storage tube, the box door is opened, and each temporary storage tube filled with collected gas is taken out. Then, the empty temporary storage tube is placed in each placement slot again, and the above-mentioned gas storage process is repeated. In the above process, the gas can enter each temporary storage tube in batches through the puncture tube for standby. This batch storage method can collect and store a large amount of gas in a shorter time. For situations where a large amount of gas samples need to be collected, this method can improve the efficiency of collection and storage and save time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to further understand the content of the present invention, the present invention is described in detail below through examples.

[0041] Example 1: Figure 1 As shown, a multi-scenario compatible water surface escape gas collection device includes a commercially available float 1, a collection body 2 connected to the upper end of the float 1, a fixed containment component 3 connected to the collection body 2, and a gas collection and detection component 4;

[0042] like Figure 3 As shown, the collection body 2 is provided with a collection cover 21 with an open structure at the upper end, and a box plug 22 is provided at the upper end of the collection cover 21. The box plug 22 is provided with a gas one-way valve 220, a gas collection hole 221 and a reserved hole 222. Among them, the gas one-way valve 220 adopts the existing technology, for example, an existing PTFE one-way valve can be used;

[0043] The fixed containment assembly 3 includes a collar 30 provided on the side wall of the collection body 2, a fixed support frame 31 that can be fixed to the ground, and a fixed connecting pipe 32 for connecting the fixed support frame 31 and the collar 30, wherein the fixed support frame 31 is a commercially available fixed bracket;

[0044] like Figure 1 、 2 As shown in FIG4 , the gas collection and detection component 4 includes a gas collection pipe 40 extending from one end through the gas collection hole 221 to the inside of the collection body 2, a gas filter 41 connected to one end of the gas collection pipe 40 located outside the collection body 2, an automatic gas collection cylinder 42 connected to the gas filter 41 and provided with a solenoid valve 420 at the connection, a connecting wire 43 extending from the inside of the collection body 2 through the reserved hole 222, a module sensor component 44 connected to one end of the connecting wire 43 located inside the collection body 2, and a single light column digital display connected to the module sensor component 44 through the connecting wire 43. The measuring and controlling instrument 45 has 20 air inlet holes 400 evenly arranged on the side wall of the gas sampling tube 40 located inside the collecting body 2. When collecting gas, the several air inlet holes 400 at the bottom end of the gas sampling tube 40 can significantly increase the area of ​​gas entering the gas sampling tube, collect gas from different positions and angles, and make the collected gas more representative. Among them, the gas filter 41, the solenoid valve 420, the automatic gas sampling cylinder 42, the connecting wire 43, and the single light column digital display measuring and controlling instrument 45 all adopt existing technologies. For example, the gas filter 41 can adopt a microporous membrane gas filter with the model number Midisart 2000, the solenoid valve 420 can adopt a Y-type solenoid valve, and the connecting wire 43 can be commercially available. The single light column digital display measuring and controlling instrument 45 can adopt a dual-circuit light column measuring and controlling instrument with the model number HD-SS803-01-23-H / LP;

[0045] The module sensing assembly 44 includes a pressure sensor 440 for real-time monitoring of air pressure changes, an electronic flow meter 441 for real-time monitoring of gas flow, and a gas composition analysis sensor 442 for comprehensive monitoring of the physical and chemical properties of the collected gas. The module sensing assembly 44 is installed in the collection body 2 and connected to the single-beam digital display measurement and control instrument 45 through the connecting wire 43. It can not only monitor the air pressure changes in the collection body 2 in real time, monitor the gas flow in real time, and comprehensively monitor the physical and chemical properties of the collected gas, but also help to gain a deeper understanding of the collected gas situation, provide rich data support for subsequent research or application, and can transmit the detection results. As for the single-light-column digital display measuring and controlling instrument 45, the single-light-column digital display measuring and controlling instrument 45 can display the data such as the air pressure change, gas flow, and physical and chemical properties of the gas in the collection body 2 detected by the module sensor component 44 in an intuitive form, so as to facilitate subsequent analysis and research. Among them, the pressure sensor 440, the electronic flow meter 441, and the gas composition analysis sensor 442 all adopt existing technologies. For example, the pressure sensor 440 can adopt a pressure sensor with a model of QDW90A, the electronic flow meter 441 can adopt an electronic flow meter with a model of PT20, and the gas composition analysis sensor 442 can adopt a gas sensor with a model of BME688.

[0046] Example 2: This example discloses a multi-scenario compatible water surface escaping gas collection method, based on a multi-scenario compatible water surface escaping gas collection device of Example 1, including the following steps:

[0047] S1. Assemble the collection body 2 and the floating plate 1, place the collection body 2 in the water area where gas needs to be collected, connect the collection body 2 to the fixed support frame 31 through the fixed connecting pipe 32, and then fix the fixed support frame 31 to the shore;

[0048] S2. Real-time monitoring of the pressure changes within the collection body 2 by means of a pressure sensor 440, real-time monitoring of the gas flow rate within the collection body 2 by means of an electronic flow meter 441, and comprehensive monitoring of the physical and chemical properties of the gas within the collection body 2 by means of a gas composition analysis sensor 442. The detected data, such as the pressure changes, gas flow rate, and physical and chemical properties of the gas within the collection body 2, are displayed in an intuitive manner by means of a single-beam digital display measurement and control instrument 45;

[0049] S3. When the water area to be collected is not equipped with an aeration device, the automatic gas collection cylinder 42 is started. By controlling the gas collection time of the automatic gas collection cylinder 42 and collecting gas at fixed intervals during the collection period, the automatic gas collection cylinder 42 extracts the gas overflowing from the collection body 2 through the gas collection pipe 40, and filters the impurities through the gas filter 41 before discharging and storing it. When the water area to be collected is equipped with an aeration device, the box plug 22 is removed from the opening on the collection cover 21, and the gas collection pipe 40 and the connecting wire 43 are clamped on the collection cover 21. At the inner wall of the opening, based on the data obtained by the electronic flow meter 441 in the module sensor assembly 44 and the total volume of the collection body 2 and the receiving cover 21, the time required for the original gas inside the collection body to be discharged is calculated by the formula T≥A / Q, where T is the time required for the original internal air in the collection body 2 and the receiving cover 21 to be discharged, A is the total volume of the collection body 2 and the receiving cover 21, and Q is the gas escape intensity displayed by the electronic flow meter 441. After the above-mentioned T time period has passed, the automatic sampling cylinder 42 can be started to collect gas;

[0050] S4. After completing the gas collection task at a certain sampling site, change the position of the fixed support frame (31), lift the collection body 2 and the floating plate 1, discharge the residual gas in the collection body 2, and then repeat steps S2-S3 to collect gas again.

[0051] Example 3: This example differs from Example 1 in that:

[0052] like Figure 4 、 5As shown, a through mounting opening 10 is provided at the center of the floating plate 1, and each inner wall of the through mounting opening 10 is provided with a sliding groove 11 with a T-shaped cross-section. The side wall of the collecting body 2 is provided with a sliding buffer bar 23 which corresponds to and is slidably connected with the sliding groove 11. The sliding buffer bar 23 includes a T-shaped sliding block 230 which can slide in the sliding groove 11, a spring buffer column 231 provided on the left and right sides of the horizontal section of the T-shaped sliding block 230, and a limiting column 232 connected to the spring buffer column 231. The end of the limiting column 232 is provided with a wear-resistant head 233; the cooperation between the sliding groove 11 and the sliding buffer bar 23 can limit the collecting body 2 in all directions, which can enhance the collection body 2 and the floating plate 1. The connection between them is firm, and when the sliding buffer strip 23 slides downward along the sliding groove 11, it is mainly limited by the T-shaped sliding block 230. The spring buffer columns 231 on the left and right sides of the horizontal section of the T-shaped sliding block 230 and the limiting columns 232 connected to the spring buffer columns 231 play the role of buffering the force at the connection between the collection body 2 and the floating plate 1, reducing the direct friction and collision between the collection body 2 and the floating plate 1 at the connection, which helps to reduce the wear of the T-shaped sliding block 230, the sliding groove 11 and other related components. In addition, since the wear-resistant head 233 is provided at the end of the limiting column 232, the wear of the limiting column 232 can be further reduced, thereby ensuring the service life of the entire device.

[0053] An inflatable floating airbag 12 is provided on the outer wall of the float plate 1, and a sealing jacket 24 is attached to the outer wall of the collection body 2. The inflatable floating airbag 12 is provided on the outer wall of the float plate 1 to increase the buoyancy of the float plate 1, thereby preventing the collection body 2 from tipping over when the water flow is turbulent, thereby ensuring the normal progress of the gas collection operation. The sealing jacket 24 is attached to the outer wall of the collection body 2 to increase the sealing performance at the connection between the collection body 2 and the float plate 1, thereby ensuring that the gas collection process is not interfered with by external gases. The floating airbag 12 is commercially available, and the sealing jacket 24 is made of polytetrafluoroethylene.

[0054] Example 4: This example differs from Example 2 in that:

[0055] In step S1, when assembling the collection body 2 and the floating plate 1, the sliding buffer strips 23 on the side walls of the collection body 2 are placed one by one in the sliding grooves 11 and slide downward along the sliding grooves 11 until the bottom end of the collection body 2 contacts the bottom end of the through-mounting opening 10, thereby completing the installation of the collection body 2 and the floating plate 1. The cooperation between the sliding grooves 11 and the sliding buffer strips 23 can limit the collection body 2 in all directions, and when the sliding buffer strips 23 slide downward along the sliding grooves 11, they are mainly limited by the T-shaped sliding block 230. The spring buffer columns 231 on the left and right sides of the horizontal section of the T-shaped sliding block 230 and the limiting columns 232 connected to the spring buffer columns 231 are used to buffer the force at the connection between the collection body 2 and the floating plate 1.

[0056] Example 5: This example differs from Example 3 in that:

[0057] like Figure 6 As shown, the outer wall of the light collecting cover 21 is provided with a reflective heat absorbing plate 25, which is composed of 4 reflective plates 250 and 4 heat absorbing plates 251 staggered and spliced ​​together, and 22 reflective columns 252 are evenly arranged on the reflective plate 250, and the outer wall of the heat absorbing plate 251 is affixed with a ceramic fiber insulation layer. The reflective heat absorbing plate 25 is arranged on the outer wall of the light collecting cover 21 to absorb and reflect external light, thereby reducing the influence of direct sunlight on the gas exchange at the water-air interface in the collecting body 2. The reflective heat absorbing plate 25 is used When the reflective panels 250 and the heat absorbing panels 251 are staggered, the reflective panels 250 can reflect the directly incident light and the heat absorbing panels 251 can absorb the heat of the sunlight, thereby preventing the external light from affecting the gas collection process. In addition, the heat absorbing panels 251 can absorb the light reflected by the adjacent reflective panels 250 for a second time, thereby further reducing the impact of external ambient temperature and pressure fluctuations on the gas collection effect. The reflective panels 250 and the heat absorbing panels 251 are both commercially available.
