In terms of equipment maintenance, the alarm as the key component of the equipment to issue an alarm is crucial for its stability. However, the alarm of the existing equipment is usually fixedly installed inside the equipment.

[0031] The technical scheme of the present application is further illustrated below by combining the drawings and through specific embodiments.

[0032] Referring to Figures 1 to 5 The carbon emission detection device provided by the embodiment of the present application comprises a shell 1 and a detection assembly 2. The shell 1 has a containing space 10 inside, and an air inlet 11 and an air outlet 12 are formed on the shell 1, and the air inlet 11 and the air outlet 12 are respectively communicated with the containing space 10; a door plate 13 is movably connected to the shell 1, and the door plate 13 is used to open or close the containing space 10; the detection assembly 2 is detachably arranged in the containing space 10, and the detection assembly 2 comprises a carbon emission detector 21 and an alarm 22, and the two are signal connected; the carbon emission detector 21 is used to detect the carbon dioxide concentration in the containing space 10, and based on the carbon dioxide concentration, the alarm 22 is controlled to issue a prompt response.

[0033] The carbon emission detection device provided by the utility model provides stable placement place for the detection assembly 2 through the accommodating space 10 in the shell 1, the setting of the air inlet 11 and the air outlet 12 enables air to circulate in the accommodating space 10, external air can enter the accommodating space 10 through the air inlet 11, and after detection by the detection assembly 2, the air flows out from the air outlet 12, so that the detection assembly 2 continuously contacts fresh air to be detected, thereby ensuring the accuracy and timeliness of carbon dioxide concentration detection and meeting the real-time monitoring requirement of carbon emission. The door plate 13 is movably connected with the shell 1, when the detection assembly 2 in the accommodating space 10 needs to be operated, the door plate 13 is opened, and the operator can conveniently approach the detection assembly 2, thereby improving the convenience of operation. The detection assembly 2 is detachably arranged in the accommodating space 10, if the carbon emission detector 21 or the alarm 22 fails, the operator does not need to complexly disassemble the whole device, only needs to take out the detection assembly 2 from the accommodating space 10, and the failed part can be repaired or replaced, thereby reducing the complexity of the maintenance process, improving the maintenance efficiency, reducing the influence of long-time shutdown maintenance of the device on the continuous monitoring of carbon emission, and effectively controlling the maintenance cost.

[0034] The specific structure of the carbon emission detection device will be described below.

[0035] The shell 1 stores the detection assembly 2 through the accommodating space 10 in the shell 1, external air enters the accommodating space 10 from the air inlet 11 and contacts the detection assembly 2, so as to realize the detection of the carbon dioxide concentration in the air.

[0036] Specifically, the fan 14 is arranged on the air inlet 11, and the fan 14 is used for sucking external air into the accommodating space 10. The operation of the fan 14 can accelerate the speed and flow of air entering the accommodating space 10, so that the carbon emission detector 21 in the detection assembly 2 can more quickly and comprehensively contact external air, thereby improving the timeliness and accuracy of detection.

[0037] The specific structure and implementation form of the fan 14 are not limited here, as long as the above-mentioned effects can be realized.

[0038] Further, the outer wall of the shell 1 is provided with a flow guide cover 15 with two open ends, one end of the flow guide cover 15 is communicated with the air inlet 11, the other end is communicated with the outside, the inner diameter of the flow guide cover 15 gradually decreases along the direction close to the air inlet 11, when air enters the flow guide cover 15 with gradually decreasing inner diameter from the wider space outside, the air flow rate will gradually increase, so that the air forms accelerated airflow before entering the air inlet 11, reduces the energy loss and turbulence phenomenon in the entering process, and ensures the efficiency and stability of air entering. At the same time, the accelerated airflow cooperates with the fan 14 at the air inlet 11, further enhances the ability of sucking external air into the accommodating space 10, and improves the air exchange efficiency.

[0039] Preferably, a filter plate 16 is arranged between the shroud 15 and the fan 14. The air flowing from the shroud 15 must pass through the filter plate 16 before entering the fan 14, so that the filter plate 16 can effectively play a filtering role. The filter plate 16 can effectively prevent various impurities that the external air may contain, such as dust, particulate matter, fibers, etc., from directly entering the detection space 10 to interfere with the detection results, thereby improving the reliability of the detection data.

[0040] In the embodiment, the outer wall of the shell 1 is provided with a positioning connector 17 arranged at the outer periphery of the air inlet 11, and the filter plate 16 is provided with a corresponding clamping groove for clamping the positioning connector 17. The end of the shroud 15 close to the air inlet 11 is fixedly connected with a fixing sleeve 18, and the fixing sleeve 18 is provided with a plurality of clamping blocks 181 along the circumferential direction thereof. The outer wall of the shell 1 is correspondingly provided with a plurality of clamping holes, and the clamping blocks 181 and the clamping holes can be matched with each other to fix the fixing sleeve 18 on the shell 1.

[0041] The air outlet 12 is provided with a mesh plate 19. The mesh plate 19 can prevent larger foreign matters such as insects and debris from entering the detection space 10 through the air outlet 12 to damage or interfere with the internal detection assembly 2 and the fan 14, thereby ensuring the normal operation of the internal components of the detection space 10.

[0042] The connection mode of the mesh plate 19 and the air outlet 12 can be bolt connection, buckle connection or latch connection, which will not be described here.

[0043] In order to facilitate the maintenance and disassembly of the detection assembly 2, the shell 1 is movably connected with a door plate 13 for opening or closing the detection space 10. Specifically, the door plate 13 is rotatably connected with the shell 1 through a rotating shaft 132, and the door plate 13 can rotate around the rotating shaft 132 to open or close the detection space 10.

[0044] Further, the door plate 13 is provided with a lock catch 131 for locking or releasing the door plate 13. Specifically, the lock catch 131 includes a rotating member and a locking strip. The rotating member can drive the locking strip to rotate between a locking position and a releasing position. When the locking strip is located at the locking position, the locking strip is extended and clamped with the inner wall of the shell 1, so that the door plate 13 is limited and cannot be moved, and the detection space 10 is in a closed state. When the locking strip is located at the releasing position, the locking strip is retracted, and the door plate 13 can freely rotate around the rotating shaft 132, so that the detection space 10 is in an open state.

[0045] In other embodiments, the door plate 13 and the shell 1 can also be slidingly connected or magnetically connected, which will not be limited here.

[0046] Preferably, the door plate 13 is provided with a sealing ring 133 at the joint with the accommodating space 10. The sealing ring 133 can effectively fill the gap at the joint of the door plate 13 and the accommodating space 10, prevent dust, water vapor, impurities and other external substances from entering the interior of the accommodating space 10, and avoid erosion and pollution of the internal precision components such as the carbon emission detector 21 and the alarm 22.

[0047] The sealing ring 133 can be selected from existing rubber rings, silica gel rings, etc., and will not be described here.

[0048] The detection assembly 2 is used to detect the carbon dioxide concentration in the air in the accommodating space 10. The carbon emission detector 21 and the alarm 22 can be selected from existing devices in the art, and the working principle and specific structure will not be described here. When the carbon emission detector 21 detects that the carbon dioxide concentration in the accommodating space 10 exceeds the set concentration value, a control instruction is generated to control the alarm 22 to issue a prompt response. The set concentration value needs to be adaptively selected according to the actual situation, and the specific value is not limited here.

[0049] In order to facilitate the disassembly and assembly of the detection assembly 2 and the accommodating space 10, the detection assembly 2 further comprises a fixed plate 23 and a bottom plate 24. The alarm 22 is arranged on the fixed plate 23, and the bottom plate 24 is fixedly connected in the accommodating space 10. One of the fixed plate 23 and the bottom plate 24 is provided with a positioning protrusion 241, and the other is provided with a corresponding positioning groove. The positioning protrusion 241 and the positioning groove can be matched with each other. The fixed plate 23 is used to install the alarm 22 and provide a stable installation platform for the alarm 22, and is used to connect the accommodating space 10. The bottom plate 24 is fixedly connected in the accommodating space 10 by cooperating with the fixed plate 23. The stable cooperation of the fixed plate 23 and the bottom plate 24 can be realized by the cooperation of the positioning protrusion 241 and the positioning groove, which prevents the two from sliding and deviating, and facilitates disassembly and assembly. Only by aligning the fixed plate 23 and the bottom plate 24 and pressing can the installation be completed, and the disassembly can be completed by reversing the pulling, which improves the disassembly efficiency.

[0050] It can be understood that in the embodiment, the bottom plate 24 is provided with the positioning protrusion 241, and the positioning groove is arranged on the fixed plate 23. In other embodiments, the fixed plate 23 can be provided with the positioning protrusion 241, and the positioning groove can be arranged on the bottom plate 24, which is not limited here.

[0051] In order to prevent the positioning protrusion 241 from being separated from the positioning groove due to shaking and the like during the carrying or the equipment operation, so that the fixed plate 23 and the bottom plate 24 are deviated, and the alarm 22 is dropped and fails, and the like, a limiting slot 231 is formed on one side of the fixed plate 23, an active slot 242 is formed on the bottom plate 24, and a limiting sliding block 25 is slidably connected in the active slot 242. The limiting sliding block 25 can move towards the limiting slot 231 or away from the limiting slot 231, and the limiting sliding block 25 can be inserted into the limiting slot 231, so as to lock the fixed plate 23 and the bottom plate 24. When it is needed to lock the fixed plate 23 and the bottom plate 24, the limiting sliding block 25 is moved towards the limiting slot 231. Since the limiting sliding block 25 and the active slot 242 are slidably connected, the flexible movement of the limiting sliding block 25 is ensured, and the limiting sliding block 25 cannot easily be separated from the active slot 242. When the limiting sliding block 25 is accurately inserted into the limiting slot 231, a mechanical locking mechanism is formed, so that the fixed plate 23 and the bottom plate 24 are tightly connected together, the shaking and displacement of the fixed plate 23 during the use are effectively prevented, the stability of the alarm 22 and the entire detection assembly 2 installed on the fixed plate 23 is ensured, and the alarm 22 can accurately receive the signal of the carbon emission detector 21 and send a prompt response.

[0052] When it is needed to disassemble the fixed plate 23 and the bottom plate 24, the limiting sliding block 25 is pushed in the opposite direction, so as to be separated from the limiting slot 231 and slide away from the limiting slot 231. At this time, the locking state between the fixed plate 23 and the bottom plate 24 is released, the fixed plate 23 is conveniently taken off from the bottom plate 24, and the alarm 22 or other components are maintained, replaced or operated. Through the connection and locking structure of the limiting slot 231, the active slot 242 and the limiting sliding block 25, the stability of the connection between the fixed plate 23 and the bottom plate 24 is enhanced, the operation is simple and easy to operate, and the maintainability and reliability of the entire carbon emission detection device are improved

[0053] Further, the sliding rod 243 is arranged in the movable slot 242, the limiting sliding block 25 is sleeved and slidably connected to the sliding rod 243, the reset spring 244 is sleeved on the sliding rod 243, one end of the reset spring 244 abuts against the limiting sliding block 25, and the other end abuts against the inner wall of the movable slot 242. The sliding rod 243 provides a stable sliding track for the limiting sliding block 25, ensures that the limiting sliding block 25 can only slide in the movable slot 242 along the axial direction of the sliding rod 243, avoids deviation or shaking of the limiting sliding block 25 in the sliding process, and makes the movement of the limiting sliding block 25 more accurate and smooth. The reset spring 244 realizes the automatic reset effect of the limiting sliding block 25. If it is necessary to disassemble the fixed plate 23, only a reverse force (i.e. a force driving the limiting sliding block 25 away from the limiting slot 231) needs to be applied to the limiting sliding block 25 to overcome the elastic force of the reset spring 244, so that the limiting sliding block 25 is separated from the limiting slot 231. After the external force on the limiting sliding block 25 is removed, the reset spring 244 quickly returns to the original state and generates an elastic force to push the limiting sliding block 25 to slide along the sliding rod 243 towards the limiting slot 231, so that the limiting sliding block 25 returns to the initial position without the need for manual secondary pushing.

[0054] Preferably, the outer surface of the limiting sliding block 25 is in a circular arc shape. The circular arc-shaped outer surface helps the limiting sliding block 25 to be better inserted into the limiting slot 231. When the limiting sliding block 25 approaches the limiting slot 231, the front end of the circular arc shape can play a guiding role, which can guide the limiting sliding block 25 to accurately align with the limiting slot 231. In addition, since the limiting sliding block 25 is in a circular arc shape, when it is necessary to fix the fixed plate 23 to the bottom plate 24, only the fixed plate 23 needs to be pressed against the bottom plate 24. During the pressing process, the limiting sliding block 25 automatically slides along the movable slot 242 away from the limiting slot 231 under the pressure of the fixed plate 23 due to the special shape of the circular arc, preventing interference with the movement of the fixed plate 23. When the positioning protrusion 241 and the positioning slot are mutually connected and matched, at this time, the limiting slot 231 is opposite to the limiting sliding block 25, and the limiting sliding block 25 moves along the direction close to the limiting slot 231 under the pushing action of the elastic force of the reset spring 244, until the limiting sliding block 25 is connected in the limiting slot 231, realizing the fixation of the fixed plate 23 and the bottom plate 24.

[0055] In other embodiments, the fixed plate 23 and the bottom plate 24 can also be connected by magnetic attraction, buckle connection, bolt connection, etc. The implementation form is not limited here, as long as the two can be disassembled and are convenient for the operator to disassemble and assemble.

[0056] It can be understood that only the detachable connection process of the alarm 22 and the accommodation space 10 is described in the embodiment, and the carbon emission detector 21 can also be connected to the accommodation space 10 by using the same connection structure as the alarm 22 or by using magnetic attraction, buckling, etc. for connection. Details are not described here.

[0057] The specific use process of the carbon emission detection device is described below.

[0058] When using the carbon emission detection device, first place the device in the area where carbon emission needs to be detected. After the device is started, the fan 14 at the air inlet 11 starts to operate, and the fairing 15 guides the external air to flow into the air inlet 11 at a high speed by virtue of its special tapered structure, and cooperates with the fan 14 to make a large amount of fresh air quickly enter the containing space 10. Before the air enters the fan 14, it will first pass through the filter plate 16, which filters out dust, particulate matter and other impurities in the air to ensure that the air entering the containing space 10 is pure and avoids interference with the detection results.

[0059] After the filtered air enters the containing space 10, the detection assembly 2 starts to work. The carbon emission detector 21 detects the carbon dioxide concentration in the air in real time, and once the carbon dioxide concentration exceeds the standard, it will immediately transmit a signal to the alarm 22 installed on the fixed plate 23. After receiving the signal, the alarm 22 sends a prompt response to remind the surrounding operators.

[0060] During the detection process, air continuously enters from the air inlet 11 and is discharged from the air outlet 12 after being detected. The mesh plate 19 of the air outlet 12 prevents foreign matter from entering the containing space 10, ensuring the normal operation of the internal components. At the same time, the sealing ring 133 at the connection between the door plate 13 and the containing space 10 effectively blocks external dust, water vapor and the like, maintaining a stable internal environment of the device.

[0061] When the detection assembly 2 needs to be repaired or replaced, first rotate the door plate 13 to open it and remove the closure of the containing space 10. Then apply a reverse force to the limiting slide block 25 to overcome the elastic force of the return spring 244, so that the limiting slide block 25 is separated from the limiting slot 231. At this time, the fixed plate 23 is pulled upward, the positioning protrusion 241 is separated from the positioning groove, and the fixed plate 23 together with the alarm 22 can be taken out of the containing space 10. Because the outer surface of the limiting slide block 25 is arc-shaped, it is easier to push during disassembly.

[0062] After the repair or replacement is completed, when installing the detection assembly 2, press the fixed plate 23 against the bottom plate 24, and the limiting slide block 25 automatically slides along the movable groove 242 away from the limiting slot 231 under the pressure of the fixed plate 23, without hindering the movement of the fixed plate 23. When the positioning protrusion 241 is accurately connected with the positioning groove, the limiting slot 231 is aligned with the limiting slide block 25, and under the elastic force of the return spring 244, the limiting slide block 25 slides into the limiting slot 231, realizing the stable connection between the fixed plate 23 and the bottom plate 24. Then close the door plate 13, and the device can continue to operate normally to continuously monitor the carbon emission situation.

[0063] The above embodiments only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the present application, and these changes and modifications all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
