Description

Technical Field

[0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a sensor for monitoring the spatial distribution of carbon dioxide. Background Art

[0002] A sensor that monitors the spatial distribution of carbon dioxide is a device used to detect the concentration of carbon dioxide in a specific space and determine its distribution. Generally speaking, the working principle of this type of sensor is to identify and measure carbon dioxide molecules in the air through specific detection elements or technologies. The sensor will convert the concentration information of carbon dioxide in the air into electrical signals or other measurable signals. These signals will be transmitted to the processing unit, and after analysis and calculation, the concentration value and spatial distribution of carbon dioxide will be obtained.

[0003] Sensors can generally directly display the concentration of carbon dioxide in a space. However, in some cases, such as plant greenhouses, industrial production or some experimental occasions, the carbon dioxide concentration in the space needs to be kept at a fixed value. After a long time, the carbon dioxide concentration in the space may be higher or lower than the fixed value, affecting the effect of production or experiments. When some existing sensors detect that the carbon dioxide concentration is too high or too low, the way of conveying data information is not intuitive enough. They may only display it on the display screen to prompt the operator to intervene. The operator may not be able to pay attention to the sensor all the time, resulting in failure to take corresponding measures in time, which has a great impact on the experimental or production results. Therefore, a sensor for monitoring the spatial distribution of carbon dioxide is proposed to address the above problems. Summary of the invention

[0004] In order to solve the problem raised in the above background technology that some sensors cannot intuitively prompt operators to intervene after monitoring, the present invention provides a sensor for monitoring the spatial distribution of carbon dioxide. When it is detected that the carbon dioxide concentration in the space is too high or too low, the output shaft of the dual-axis motor can be driven to rotate clockwise or counterclockwise through the circuit system, and the rotating block can be driven to rotate continuously, so that the alarm bell keeps sounding to prompt the operator that the carbon dioxide amount in the space is abnormal. It is more intuitive, and the operator can respond quickly and take corresponding measures to adjust the concentration of carbon dioxide to avoid adverse effects on production, experiments or the environment.

[0005] To achieve the above object, the present invention provides the following technical solution: a sensor for monitoring the spatial distribution of carbon dioxide, comprising a shell, the top outer wall of the shell being provided with an alarm mechanism;

[0006] The alarm mechanism includes a fixed block, the inner wall of the fixed block is fixedly connected to a dual-axis motor, the output shaft of the dual-axis motor is fixedly connected to a rotating block, the outer wall of the rotating block is fixedly connected to a connecting block, the inner wall of the connecting block is elastically connected to a rotating shaft via a volute spring, the outer wall of the rotating shaft is fixedly connected to a knocking block, the front end outer wall of the fixed block is fixedly connected to an alarm, the inner wall of the fixed block is provided with a control mechanism, the rear end outer wall of the shell contacts a wall, and the inner wall of the wall is fixedly connected to a conveying pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention is provided with a shell and a double-axis motor and other structures. When the shell detects that the carbon dioxide concentration in the space is too high or too low, the output shaft of the double-axis motor can be driven to rotate clockwise or counterclockwise through the circuit system, and the rotating block is driven to rotate continuously, so that the four groups of knocking blocks on the outer wall are continuously in contact with the outer wall of the alarm bell, so that the alarm bell can continuously sound to remind the operator that the carbon dioxide amount in the space is abnormal.

The overall structure of the device is simple, which is convenient for later maintenance and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, the present invention provides a sensor for monitoring the spatial distribution of carbon dioxide, including a shell 1, an outer wall of the top end of the shell 1 is provided with an alarm mechanism 2, the alarm mechanism 2 includes a fixed block 201, the inner wall of the fixed block 201 is fixedly connected with a dual-axis motor 202, the output shaft of the dual-axis motor 202 is fixedly connected with a rotating block 203, the outer wall of the rotating block 203 is fixedly connected with a connecting block 205, the inner wall of the connecting block 205 is elastically connected with a rotating shaft 207 through a volute spring 206, the outer wall of the rotating shaft 207 is fixedly connected with a knocking block 208, the front end outer wall of the fixed block 201 is fixedly connected with an alarm 204, the inner wall of the fixed block 201 is provided with a control mechanism 3, the rear end outer wall of the shell 1 contacts with a wall 4, and the inner wall of the wall 4 is fixedly connected with a conveying pipe 5.

[0028] The above scheme is adopted: the shell 1 is the sensor body for detecting the spatial distribution of carbon dioxide, which is the prior art. The shell 1 can be installed on the wall 4 and placed under the delivery pipe 5. The delivery pipe 5 can continuously deliver carbon dioxide to the space, such as in a plant greenhouse, industrial production or some experimental occasions. Through the alarm mechanism 2, when the shell 1 detects that the carbon dioxide concentration in the space is too high or too low, the alarm 204 will sound to remind the operator, and the control mechanism 3 will adjust the delivery amount of carbon dioxide in the delivery pipe 5 to keep the carbon dioxide in the space at a normal amount; the shell 1 is electrically connected to the dual-axis motor 202. When the carbon dioxide concentration is too high or too low, the internal controller of the shell 1 receives a signal and sends a command to the dual-axis motor 202 to rotate its output shaft; Figure 5 , Figure 6As shown, when the carbon dioxide concentration is too low, the output shaft of the dual-axis motor 202 rotates clockwise, and when the carbon dioxide concentration is too high, the output shaft rotates counterclockwise.

[0029] like Figure 2 and Figure 4 As shown, the fixed block 201 is fixedly connected to the top outer wall of the shell 1, and the outer wall of the knocking block 208 contacts the outer wall of the alarm 204; one end of the spiral spring 206 is fixedly connected to the outer wall of the rotating shaft 207, and the other end of the spiral spring 206 is fixedly connected to the outer wall of the rotating shaft 207; the outer wall of the rotating shaft 207 is rotatably connected to the inner wall of the connecting block 205, and the connecting block 205 is provided with four groups; the outer wall of the rotating block 203 is rotatably connected to the front end outer wall of the fixed block 201, and the connecting block 205 is concave.

[0030] The above scheme is adopted: when the dual-axis motor 202 receives a signal, the output shaft at its front end rotates, driving the rotating block 203 to rotate synchronously, so that the connecting block 205 arranged on the outer wall drives the knocking block 208 to rotate. Since the alarm 204 is arranged below the rotating block 203, during the rotation process, the four groups of knocking blocks 208 will continuously contact the outer wall of the alarm 204, so that the alarm 204 continuously emits a sound to remind the operator that the carbon dioxide concentration in the space is not up to standard; when a group of knocking blocks 208 and the alarm 204 are in contact, the alarm 204 will continuously emit a sound to remind the operator that the carbon dioxide concentration in the space is not up to standard. 04, the knocking block 208 is squeezed by the outer wall of the alarm 204 and rotates around the shaft 207 as the axis. The shaft 207 rotates synchronously, causing the end of the spiral spring 206 connected to it to shrink. When the knocking block 208 of this group rotates to lose contact with the outer wall of the alarm 204, the shaft 207 drives the knocking block 208 to rotate in the opposite direction due to the elastic force of the spiral spring 206 itself, so that the knocking block 208 can maintain its initial state, so that the alarm 204 can be continuously knocked to make a sound through the continuous rotation of the rotating block.

[0031] like Figure 5 and Figure 6 As shown, the control mechanism 3 includes a synchronous wheel A301, the outer wall of the synchronous wheel A301 is connected to the synchronous wheel B303 through a synchronous belt 302, the rear end outer wall of the synchronous wheel B303 is fixedly connected to the rotating wheel 304, the outer wall of the rotating wheel 304 is fixedly connected to the tooth block A305, the rear end inner wall of the fixed block 201 is slidably connected to the baffle 306, the bottom end outer wall of the baffle 306 is fixedly connected to the moving block 307, the outer wall of the moving block 307 is fixedly connected to the tooth block B310, and the inner wall of the moving block 307 is elastically connected to the wedge block 309 via a telescopic spring 308.

[0032] The above scheme is adopted: the front output shaft of the dual-axis motor 202 is fixedly connected to the rotating block 203, and the rear output shaft is fixedly connected to the synchronous wheel A301, and the output shafts at the front and rear ends rotate synchronously; when the output shaft of the dual-axis motor 202 drives the rotating block 203 to rotate clockwise or counterclockwise, the synchronous wheel A301 rotates synchronously, and can drive the synchronous wheel B303 to rotate through the transmission of the synchronous belt 302. The outer walls of the synchronous wheels A301 and B303 are provided with latch teeth, and the outer wall of the synchronous belt 302 is also provided with latch teeth. The engagement of the latch teeth of the three can achieve a transmission effect, which are all prior arts; the rotation of the synchronous wheel B303 can drive the moving block 307 and the baffle 306 to move upward or downward, and the baffle 306 corresponds to the opening position of the conveying pipe 5. The size of the opening of the conveying pipe 5 can be adjusted by moving the baffle 306, thereby controlling the delivery amount of carbon dioxide, so that the carbon dioxide concentration in the space is maintained at an appropriate amount.

[0033] like Figure 5 and Figure 6 As shown, the synchronous wheel A301 is fixedly connected to the output shaft of the dual-axis motor 202, and the synchronous wheel B303 is rotatably connected to the inner wall of the fixed block 201; the tooth block A305 is meshed with the tooth block B310, and the tooth block A305 contacts the outer wall of the wedge block 309; one end of the telescopic spring 308 is fixedly connected to the outer wall of the wedge block 309, and the other end of the telescopic spring 308 is fixedly connected to the inner wall of the moving block 307; the outer wall of the wedge block 309 is slidably connected to the inner wall of the moving block 307, and the baffle 306 contacts the outer wall of the conveying pipe 5.

[0034] The above scheme is adopted: when the concentration of carbon dioxide is too low, the output shaft of the dual-axis motor 202 rotates clockwise, driving the synchronous wheel A301 and the synchronous wheel B303 to rotate clockwise, and the synchronous wheel B303 drives the rotating wheel 304 on its outer wall to rotate synchronously, and the tooth block A305 on the outer wall of the rotating wheel 304 is meshed with the tooth block B310 on the outer wall of the moving block 307. When the rotating wheel 304 rotates, it can drive the moving block 307 to move downward, and the baffle 306 can be moved downward to expose more of the opening of the delivery pipe 5, so that more carbon dioxide can be transported into the space, so that the carbon dioxide in the space reaches the required value faster; and when the concentration of carbon dioxide is too high, its output shaft rotates counterclockwise, driving the baffle 306 to move upward, closing more of the opening of the delivery pipe 5, and reducing the delivery amount of carbon dioxide.

[0035] There are two groups of wedge blocks 309, which are symmetrically distributed on the upper and lower sides of the moving block 307. The arc surface of the upper wedge block 309 faces upward and the arc surface of the lower wedge block 309 faces downward. When the baffle 306 moves upward or downward until the tooth block A305 is out of contact with the tooth block B310, the tooth block A305 contacts the outer wall of the wedge block 309. At this time, the rotating wheel 304 continues to rotate, and the tooth block A305 is constantly in contact with the arc surface of the wedge block 309, so that the wedge block 309 is squeezed and moves inward along the inner wall of the moving block 307. The telescopic spring 308 is contracted by the force and pops out when the tooth block A305 is out of contact with the wedge block 309, thereby maintaining the position of the moving block 307 and the baffle 306. Therefore, when the carbon dioxide concentration in the space is too high or too low, the alarm 204 is used to remind the operator and the carbon dioxide delivery amount can be automatically adjusted through the baffle 306. The device has a simple structure and a high degree of automation.

[0036] The working principle and use process of the present invention:

[0037] The shell 1 is a sensor body for detecting the spatial distribution of carbon dioxide. It is installed on the wall 4 and is located below the delivery pipe 5. The delivery pipe 5 is used to deliver carbon dioxide to the space, such as a plant greenhouse, industrial production or experimental occasions. When the shell 1 detects that the carbon dioxide concentration in the space is too high or too low, the internal controller of the shell 1 receives a signal and sends an instruction to the dual-axis motor 202. The dual-axis motor 202 can make the alarm mechanism 2 sound to remind the operator that the carbon dioxide concentration in the space does not meet the standard, and the control mechanism 3 can be rotated to adjust the delivery amount of carbon dioxide. When the carbon dioxide concentration is too low, the output shaft of the dual-axis motor 202 rotates clockwise; when the carbon dioxide concentration is too high, its output shaft rotates counterclockwise.

[0038] When the output shaft of the dual-axis motor 202 rotates, it drives the rotating block 203 to rotate synchronously, and the connecting block 205 provided on the outer wall of the rotating block 203 drives the knocking block 208 to rotate. The four groups of knocking blocks 208 will continuously contact the outer wall of the alarm bell 204 below, so that the alarm bell 204 continuously emits sounds to remind the operator that the carbon dioxide concentration is not up to standard; after one group of knocking blocks 208 contacts the alarm bell 204, the knocking blocks 208 are squeezed by the outer wall of the alarm bell 204, and rotate around the rotating shaft 207 as the axis, and can drive the rotating shaft 207 to rotate synchronously, so that the spiral spring 2 06, one end connected to it shrinks, and when the knocking block 208 of the group continues to rotate until it loses contact with the outer wall of the alarm bell 204, the rotating shaft 207 drives the knocking block 208 to rotate in the opposite direction due to the elastic force of the spiral spring 206 itself, so that the knocking block 208 maintains the initial state, so that the alarm bell 204 can be continuously knocked to make a sound through the continuous rotation of the rotating block 203; when the rotating block 203 rotates clockwise or counterclockwise, the knocking block 208 can make a sound by contacting the alarm bell 204, so that the operator can check the situation in the space as soon as possible and take corresponding measures.

[0039] When the front output shaft of the dual-axis motor 202 drives the rotating block 203 to rotate, its rear output shaft can rotate synchronously with the synchronous wheel A301; when the carbon dioxide concentration is too low, the output shaft of the dual-axis motor 202 rotates clockwise, driving the synchronous wheels A301 and B303 to rotate clockwise, and the synchronous wheel B303 drives the rotating wheel 304 on its outer wall to rotate synchronously, and the tooth block A305 on the outer wall of the rotating wheel 304 is engaged with the tooth block B310 on the outer wall of the moving block 307. When the rotating wheel 304 rotates, it can drive the moving block 307 to move downward, and move the baffle 306 downward, so that the opening of the delivery pipe 5 is exposed more, thereby delivering more carbon dioxide into the space, so that the carbon dioxide in the space reaches the required value faster.

[0040] When the carbon dioxide concentration is too high, the output shaft of the dual-axis motor 202 rotates counterclockwise, driving the baffle 306 to move upward, closing a larger part of the opening of the delivery pipe 5 and reducing the delivery amount of carbon dioxide; and when the baffle 306 moves upward or downward until the tooth block A305 is out of contact with the tooth block B310, the tooth block A305 contacts the outer wall of the wedge block 309 below or above, and the rotating wheel 304 continues to rotate. The tooth block A305 is constantly in contact with the arc surface of the wedge block 309, so that the wedge block 309 is squeezed and moves inward along the inner wall of the moving block 307, and the telescopic spring 308 is forced to shrink. When the tooth block A305 is out of contact with the wedge block 309, the wedge block 309 pops outward to maintain the position of the moving block 307 and the baffle 306.

[0041] In summary, when the carbon dioxide concentration in the space is too high or too low, the device prompts the operator through the alarm 204. Before the operator intervenes to make adjustments, the carbon dioxide delivery rate can be automatically adjusted through the control mechanism 3. It has high efficiency, simple structure and high degree of automation.
