Description

Technical Field

[0002] Greenhouse gases refer to gases in the atmosphere that absorb longwave radiation reflected from the ground and re-emit it, such as water vapor, carbon dioxide, and most refrigerants. Their effect is to warm the Earth's surface, similar to how a greenhouse traps solar radiation and heats the air inside. This warming effect of greenhouse gases is called the "greenhouse effect." Water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), freons, and methane (CH4) are the main greenhouse gases in the Earth's atmosphere. Monitoring greenhouse gases typically requires the use of greenhouse gas monitoring devices.

[0003] After searching, Chinese patent application No. 202122746351.5 discloses a greenhouse gas monitoring device, which belongs to the technical field of gas detection equipment, including a device housing and a gas pipe opened inside the device housing, and an air inlet is provided at the bottom end of the gas pipe. One side of the device housing is fixedly connected to an adjustment housing, and the interior of the adjustment housing is provided with a mounting mechanism, and the mounting mechanism includes a bidirectional screw. The bidirectional screw is controlled by a knob, and the distance between the two clamping blocks is changed by rotating the bidirectional screw, which facilitates the installation of the monitoring device, and the fixed suction cup makes the monitoring device more firmly installed. The two sides of the movable box are symmetrically fixed with a plug-in rod, and the plug-in rod is an L-shaped structure, which facilitates the connection between the movable box and the pull-out cabinet, and is convenient for replacing the filter cotton. The second filter is located below the filter cotton to screen the gas step by step to prevent dust and other impurities from entering the gas pipe and being adsorbed on the monitoring device, affecting the use of the monitoring device.

[0004] Although the above patent changes the distance between the two clamping blocks by rotating the bidirectional screw, facilitating the installation of the monitoring device, and the fixed suction cup makes the monitoring device more firmly installed, the two sides of the movable box are symmetrically fixed with plug-in rods, which are L-shaped structures, convenient for the connection between the movable box and the pull-out cabinet, and convenient for replacing the filter cotton.

Greenhouse gases enter the air inlet pipe through the air inlet, and then enter the gas monitor body for monitoring. When the air intake volume needs to be adjusted, the forward and reverse motors can be started. The forward rotation of the forward and reverse motors drives the screw to rotate forward. When the screw rotates forward, it drives the screw block to move right. The rightward movement of the screw block drives the gas monitor body to move right. When the gas monitor body moves to the right, it drives the air inlet pipe to move right. Since the center point of the air inlet pipe and the center point of the air inlet are in the same plane, when the air inlet pipe moves to the right, it moves with the air inlet on the right side, which becomes smaller in sequence. The air inlets overlap. When the air inlet pipe overlaps with the smaller air inlet, the air intake volume becomes smaller. Conversely, the forward and reverse motors can be reversed to drive the screw to reverse, move the screw block to the left, and drive the gas monitor body and the air inlet pipe to move to the left, so that the air inlet pipe overlaps with the larger air inlet, thereby increasing the air intake volume. At the same time, when the device is in use, the air inlet pipe is always inside the sealed shell to protect the air inlet pipe. In this way, the air intake volume can be adjusted according to the different greenhouse gases. It is suitable for a variety of monitoring locations, protects the air inlet pipe, increases the service life of the air inlet pipe, and is convenient for users to use.

[0015] 2. The utility model sets a compression spring and a buffer plate for use together. When the gas monitor body moves to the leftmost or rightmost side, the gas monitor body contacts the buffer plate, and the compression spring contracts to protect the gas monitor body, thereby avoiding the gas monitor body colliding with the sealing shell, causing damage to the gas monitor body and affecting its use. By setting a sensing block, when the gas monitor body moves to the leftmost or rightmost side, the sensing block contacts the inner wall of the sealing shell, sending a signal to the forward and reverse motors to stop rotating, thereby avoiding the forward and reverse motors excessively rotating to cause damage to the gas monitor body.

[0023] refer to Figure 4The buffer mechanism 10 includes a compression spring 11 fixedly connected to the left and right sides of the inner wall of the sealed shell 2, the inner end of the compression spring 11 is fixedly connected to a buffer plate 12, and the outer side of the buffer plate 12 is fixedly connected to a sensor block 13. The sensor block 13 is electrically connected to the forward and reverse motor 9, and the left side of the sensor block 13 located on the left side is in contact with the left side of the inner wall of the sealed shell 2.

[0024] As a technical optimization solution of the present invention, by setting the cooperation of the compression spring 11 and the buffer plate 12, when the gas monitor body 3 moves to the leftmost or rightmost side, the gas monitor body 3 contacts the buffer plate 12, and the compression spring 11 contracts to protect the gas monitor body 3, thereby avoiding the collision between the gas monitor body 3 and the sealing shell 2, causing damage to the gas monitor body 3 and affecting the use. By setting the sensing block 13, when the gas monitor body 3 moves to the leftmost or rightmost side, the sensing block 13 contacts the inner wall of the sealing shell 2, and sends a signal to the forward and reverse motor 9 to stop rotating, thereby avoiding the excessive rotation of the forward and reverse motor 9 and causing damage to the gas monitor body 3.

[0025] refer to Figure 2 The left and right sides of the sealed shell 2 are fixedly connected to the electric telescopic rod 14 through the support plate. The top of the electric telescopic rod 14 is fixedly connected to the sealing cover 15 located above the sealed shell 2, and the bottom of the sealing cover 15 is fixedly connected to the sealing gasket 16.

[0026] As a technical optimization solution of the present invention, by setting up the coordinated use of the electric telescopic rod 14, the sealing cover 15 and the sealing gasket 16, when the device is not in use, the electric telescopic rod 14 can be started to retract, driving the sealing cover 15 to move downward, so that the bottom of the sealing cover 15 fits with the top of the sealing shell 2, and the sealing gasket 16 seals the air inlet 6, thereby preventing dust and impurities from entering the interior of the sealing shell 2 when the device is not in use, thereby affecting the monitoring effect.

[0027] refer to Figure 3 The four corners of the front and rear sides of the gas monitor body 3 are fixedly connected with T-shaped sliders 17, and the upper and lower sides of the front and rear sides of the inner wall of the sealing shell 2 are fixedly connected with track grooves 18, and the surface of the T-shaped slider 17 is slidably connected to the inner wall of the track groove 18.

[0028] As a technical optimization solution of the present invention, by setting up the T-shaped slider 17 and the track groove 18, the gas monitor body 3 is positioned and reinforced so that it can only move horizontally inside the sealing shell 2, avoiding the gas monitor body 3 from shaking and tilting during movement, resulting in the sealing rubber sleeve 5 not being able to fit tightly with the top of the sealing shell 2, resulting in air leakage affecting the air intake.

[0029] refer to Figure 1A data display screen 19 is provided on the front of the gas monitor body 3 , a square groove 20 is provided on the front of the sealed shell 2 , and a transparent glass 21 is fixedly connected to the interior of the square groove 20 .

[0030] As a technical optimization solution of the present invention, by setting a data display screen 19, the monitoring data can be displayed on it in real time. By setting a square groove 20 and a transparent glass 21, the user can see the data on the data display screen 19 more intuitively and conveniently without affecting the sealing effect of the sealing shell 2, which further facilitates the user's use.

[0031] refer to Figure 3 The four corners of the bottom of the gas monitor body 3 are fixedly connected with pulleys 22, and the front and rear sides of the top of the bottom plate 1 are provided with slide grooves 23 located inside the sealed shell 2, and the bottom of the pulley 22 is rollingly connected to the inner wall of the slide groove 23.

[0032] As a technical optimization solution of the present invention, by setting the pulley 22 and the slide groove 23 for use in conjunction, a supporting effect is played on the bottom of the gas monitor body 3, and at the same time, the friction between the bottom of the gas monitor body 3 and the top of the base plate 1 during movement is reduced, making it smoother when moving, and avoiding the gas monitor body 3 from falling and affecting its use.

[0033] The working principle and use process of the utility model are as follows: by placing the device at a place where monitoring is required, greenhouse gases enter the air inlet pipe 4 through the air inlet 6, and then enter the gas monitor body 3 for monitoring. When the air intake volume needs to be adjusted, the forward and reverse motor 9 can be started, and the forward rotation of the forward and reverse motor 9 drives the screw 8 to rotate forward. When the screw 8 rotates forward, it drives the screw block 7 to move right, and the rightward movement of the screw block 7 drives the gas monitor body 3 to move right. When the gas monitor body 3 moves right, it drives the air inlet pipe 4 to move right. Since the center point of the air inlet pipe 4 and the center point of the air inlet 6 are in the same plane, when the air inlet pipe 4 moves to the right, it moves in parallel with the right side. The air inlet 6 becomes smaller and smaller. When the air inlet pipe 4 overlaps with the smaller air inlet 6, the air intake volume becomes smaller. Conversely, the forward and reverse motor 9 can be reversed to drive the screw 8 to reverse, so that the screw block 7 moves to the left, and drives the gas monitor body 3 and the air inlet pipe 4 to move to the left, so that the air inlet pipe 4 overlaps with the larger air inlet 6, thereby increasing the air intake volume. At the same time, when the device is in use, the air inlet pipe 4 is always inside the sealed shell 2 to protect the air inlet pipe 4. In this way, the air intake volume can be adjusted according to the different greenhouse gases. It is suitable for a variety of monitoring locations, protects the air inlet pipe 4, increases the service life of the air inlet pipe 4, and is convenient for users to use.
