Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a gas emission detection device. Background Technology

[0002] Carbon emissions refer to the amount of greenhouse gases emitted, whether naturally occurring or due to human activities. To align with the current trend of green, low-carbon, and circular development, carbon emission monitoring devices are typically used to measure and rigorously monitor carbon emissions. When these devices are installed in open-air environments, dust easily accumulates inside, affecting the accuracy of the data. To improve dust protection, the devices can be placed in a protective enclosure, but this also increases the difficulty of inspection and maintenance.

[0003] To simplify the inspection and maintenance of equipment inside the protective enclosure, the related technology discloses a shell and an installation structure. The inner wall of the shell is equipped with a slide rail, and the installation structure is provided with a sliding component that slides with the slide rail. An external handle is connected. Pulling or pushing the handle can pull the installation structure out or push it into the shell, which facilitates the replacement or maintenance of the installation structure inside the shell.

[0004] The aforementioned housing is equipped with a limiting seat, and the mounting structure has limiting blocks on both sides that cooperate with the limiting seat. When the handle is pushed, the mounting structure can engage with the limiting seat, thus fixing the mounting structure relative to the housing. However, this method is only suitable for fixing mounting structures of specific sizes. If the mounting structure is too large, it cannot be installed into the housing; if it is too small, the fixing effect with the housing is poor. In other words, the above-mentioned equipment has high requirements for the machining precision of the mounting structure and has poor versatility. Utility Model Content

[0005] The purpose of this invention is to provide a gas emission detection device that can reduce the processing precision requirements of the detection components, enhance the fixing effect of the detection components, and improve the versatility of the device.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model discloses a gas emission detection device, comprising:

[0008] Detection components;

[0009] The protective enclosure includes a housing and a protective door. The housing has an opening, and a mounting bracket is fixedly installed on the protective door. The detection component can be installed on the mounting bracket, and the protective door is movably connected to the housing. The protective door has a working position and a maintenance position. When the protective door is in the working position, the protective door closes the opening, and both the mounting bracket and the detection component are inside the housing. When the protective door is in the maintenance position, the mounting bracket extends at least partially outside the housing, and the detection component is located outside the housing.

[0010] The clamping assembly includes a first clamping member and a second clamping member, at least one of which is adjustablely disposed on the mounting bracket to clamp or release the detection assembly.

[0011] Optionally, at least one of the first clamping member and the second clamping member is slidably connected to the mounting bracket.

[0012] Specifically, the mounting bracket is provided with positioning elements, which are respectively engaged with the first clamping element and the second clamping element, so that the first clamping element and the second clamping element clamp the detection component in a preset position.

[0013] Specifically, the gas emission detection device also includes a first locking member and a second locking member. The mounting bracket is provided with a plurality of first locking holes and a plurality of second locking holes spaced apart along the length direction. The first locking member is detachably inserted through any of the first locking holes, and the second locking member is detachably inserted through any of the second locking holes.

[0014] Optionally, the gas emission detection device also includes a suction element located inside the housing, which is capable of delivering the gas to be tested to the detection component.

[0015] Specifically, the gas emission detection device also includes a protective component, which includes a protective housing, a first filter element, and a second filter element. The protective housing is movably connected inside the housing. An air inlet is provided on the side of the protective housing away from the detection component, and an air outlet is provided on the side closer to the detection component. The first filter element is detachably installed at the air inlet, and the second filter element is detachably installed at the air outlet. A suction component is installed inside the protective housing and is able to draw in the gas to be tested through the air inlet and deliver it to the detection component through the air outlet.

[0016] Optionally, the protective enclosure and the housing are hinged or slidably connected.

[0017] Optionally, the mounting bracket is slidably connected to the inner wall of the housing. The mounting bracket can slide along a first direction to switch the protective door from the working position to the maintenance position; the mounting bracket can slide along a second direction to switch the protective door from the maintenance position to the working position. The first direction and the second direction are opposite.

[0018] Optionally, the detection component includes a first guide port, a detection chamber, and a second guide port connected in sequence. Along the flow direction of the gas to be measured, the cross-sectional size of the first guide port gradually decreases, and the cross-sectional size of the second guide port gradually increases.

[0019] Specifically, a limiting part is provided inside the housing, and when the protective door is in the working position, the limiting part and the second guide port are in contact.

[0020] The beneficial effects of this utility model are:

[0021] This invention proposes a gas emission detection device. At least one of the first clamping member and the second clamping member is adjustablely positioned on the mounting frame. The distance between the first clamping member and the second clamping member can be flexibly adjusted according to the size of the detection component to accommodate detection components of different sizes. This improves the versatility of the device, reduces the requirements for the processing precision of the detection component, and enhances the clamping effect on the detection component. When the first clamping member and the second clamping member clamp the detection component, the detection component can move synchronously with the mounting frame. When the protective door is in the working position, both the mounting frame and the detection component are located inside the housing, at which point the emission quantity of the gas to be tested is detected. When the protective door is in the maintenance position, the mounting bracket extends at least partially outside the housing, and the detection component is located outside the housing. This allows maintenance personnel to visually inspect the detection component periodically. When the detection component needs to be replaced, the relative positions of the first and second clamping members can be adjusted to increase the distance between them, thereby allowing the detection component to be released from the mounting bracket. This gas emission detection device does not require maintenance personnel to enter the narrow space inside the housing during maintenance, reducing the difficulty of maintenance and making the replacement process of the detection component simple and easy to implement.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1-5As shown, this embodiment provides a gas emission detection device, including a detection component 1, a protective housing 2, and a clamping component 3. The protective housing 2 includes a shell 21 and a protective door 22. The shell 21 has an opening, and a mounting bracket 221 is fixedly mounted on the protective door 22. The detection component 1 can be mounted on the mounting bracket 221, and the protective door 22 is movably connected to the shell 21. The protective door 22 has a working position and a maintenance position. When the protective door 22 is in the working position, it closes the opening of the shell 21, and the mounting bracket 221 and the detection component 1 are both inside the shell 21. The shell 21 has a first opening and a second opening on its two sides. An inlet pipe 9 is provided at the first opening to allow the gas to be tested to flow into the shell 21, and an exhaust pipe 10 is provided at the second opening to promptly discharge the gas to be tested from the shell 21 and allow it to flow to subsequent processing equipment. When the protective door 22 is in the working position, the detection component 1 can detect the emission amount of the gas to be tested that enters through the inlet pipe 9 and exits through the exhaust pipe 10. Specifically, as shown... Figure 1 and Figure 2 As shown, in this embodiment, a display screen 211 is also provided on the outside of the housing 21. The display screen 211 is electrically connected to the detection component 1, and the operator can intuitively obtain the detection results on the display screen 211. The emission detection method in this utility model is prior art and will not be described in detail here.

[0043] When the protective door 22 is in the maintenance position, the mounting bracket 221 extends at least partially outside the housing 21, and the detection component 1 is located outside the housing 21. The clamping assembly 3 includes a first clamping member 31 and a second clamping member 32. At least one of the first clamping member 31 and the second clamping member 32 is adjustablely positioned on the mounting bracket 221 to clamp or release the detection component 1. The distance between the first clamping member 31 and the second clamping member 32 can be flexibly adjusted according to the specific dimensions of the detection component 1. The gas emission detection device proposed in this utility model can adapt to detection components 1 of different sizes. The device has strong versatility and low requirements for the dimensional accuracy of the detection component 1, and has a good clamping and fixing effect on the detection component 1.

[0044] A mounting bracket 221 is fixedly mounted on the protective door 22, and the protective door 22 is movably connected to the housing 21. In one embodiment, the protective door 22 can be movably connected to the housing 21 via the mounting bracket 221, which is movable relative to the housing 21. The movement of the mounting bracket 221 relative to the housing 21 allows the protective door 22 to switch between a working position and a maintenance position. At least one of the first clamping member 31 and the second clamping member 32 is adjustablely mounted on the mounting bracket 221. When it is necessary to detect the emission amount of the gas to be tested, the operator can adjust the relative positions of the first clamping member 31 and the second clamping member 32 on the mounting bracket 221, so that the first clamping member 31 and the second clamping member 32 clamp and fix the detection component 1 to the mounting bracket 221, thereby enabling the detection component 1 to move synchronously with the mounting bracket 221. When the mounting bracket 221 moves in the direction close to the housing 21, it can drive the protective door 22 and the detection component 1 to move in the direction close to the housing 21 until the protective door 22 closes the opening of the housing 21. When the protective door 22 closes the opening of the housing 21, the protective door 22 reaches the working position. The mounting bracket 221 and the detection component 1 are both located inside the housing 21. The detection component 1 detects the emission amount of the circulating gas to be tested.

[0045] When internal maintenance of the gas emission detection device is required, the operator can manipulate the mounting bracket 221 to move it away from the housing 21 until the mounting bracket 221 moves the detection component 1 completely out of the housing 21, at which point the protective door 22 reaches the maintenance position. The operator does not need to enter the confined space inside the housing 21 to perform maintenance on the detection component 1; the movement of the mounting bracket 221 relative to the housing 21 allows the detection component 1 to be moved to the outside of the housing 21, providing the operator with a direct view of the detection component 1's condition. When the detection component 1 needs to be replaced, the operator can adjust the relative positions of the first clamping member 31 and the second clamping member 32, increasing the distance between them to allow the detection component 1 to be removed from the mounting bracket 221. The maintenance and replacement process for the detection component 1 is simple, reducing both the difficulty and cost of maintenance. The first clamping member 31 and the second clamping member 32 are adjustablely positioned on the mounting bracket 221, which can clamp and fix the detection component 1 when it is performing normal detection operations, and can also be adjusted flexibly by the clamping member 3 when the detection component 1 needs to be repaired, so as to facilitate the maintenance and replacement of the detection component 1.

[0046] To enable the protective door 22 to switch between the working position and the maintenance position, in this embodiment, the mounting bracket 221 is slidably connected to the housing 21. The mounting bracket 221 can slide along a first direction to switch the protective door 22 from the working position to the maintenance position; the mounting bracket 221 can also slide along a second direction to switch the protective door 22 from the maintenance position to the working position. The first and second directions are opposite in direction. The first direction is the direction away from the housing 21, and the second direction is the direction closer to the housing 21. The switching of the protective door 22 between the working position and the maintenance position can be achieved through the sliding process of the mounting bracket 221, which is simple and does not require a complicated disassembly process.

[0047] Specifically, of the mounting bracket 221 and the housing 21, one has a sliding groove, and the other has a guide protrusion that can slide along the sliding groove, so as to achieve a sliding fit between the mounting bracket 221 and the housing 21. In this embodiment, the mounting bracket 221 has a sliding groove, and the housing 21 has a guide protrusion inside. To avoid interference between the sliding process of the mounting bracket 221 and the sliding process of the clamping assembly 3, the sliding groove is formed on the surface of the mounting bracket 221 near the housing 21, and the clamping assembly 3 slides in fit with the upper and lower surfaces of the mounting bracket 221.

[0048] The sliding process of the mounting bracket 221 can be achieved by an electric drive device such as a drive motor, or by manual operation. To facilitate manual operation of the mounting bracket 221, in this embodiment, a handle 222 is installed on the side of the protective door 22 away from the housing 21. Pulling the handle 222 will slide the mounting bracket 221 along the first direction, and pushing the handle 222 will slide the mounting bracket 221 along the second direction.

[0049] In another embodiment, the mounting bracket 221 and the housing 21 can also be connected by a retractable robotic arm. When the robotic arm retracts, it can move the mounting bracket 221 closer to the housing 21 until the protective door 22 reaches the working position. The mounting bracket 221 is completely inside the housing 21. The two ends of the detection component 1 are connected to the air inlet pipe 9 and the exhaust pipe 10, respectively, and the detection component 1 detects the emission amount of the gas to be tested. When the robotic arm extends, it can move the mounting bracket 221 away from the housing 21 until the protective door 22 reaches the maintenance position. The detection component 1 is completely exposed outside the housing 21, which facilitates the operator to maintain the detection component 1.

[0050] In other embodiments, the protective door 22 may also be hinged to the housing 21. The protective door 22 and the mounting bracket 221 are connected by a linkage structure, and the protective door 22 can switch between the working position and the maintenance position by rotation. When the protective door 22 rotates away from the housing 21, the protective door 22 can drive the mounting bracket 221 to move at least partially out of the housing 21 through the transmission of the linkage structure. When the protective door 22 rotates towards the housing 21, the protective door 22 can drive the mounting bracket 221 into the housing 21 by the transmission of the linkage structure.

[0051] To achieve adjustable positions of the first clamping member 31 and the second clamping member 32 on the mounting frame 221, at least one of the first clamping member 31 and the second clamping member 32 can be slidably connected to the mounting frame 221, so that the first clamping member 31 and the second clamping member 32 can slide relative to each other along the mounting frame 221. Different sizes of detection components 1 can be adapted without frequent replacement of clamping components 3. The clamping process is simple and easy to implement, and the clamping effect of the first clamping member 31 and the second clamping member 32 on detection components 1 of different specifications is better than the fixing effect of the snap-fit ​​method in the prior art.

[0052] In this embodiment, the first clamping member 31 and the second clamping member 32 are both slidably connected to the mounting frame 221. The first clamping member 31 and the second clamping member 32 are located on both sides of the detection component 1. The operator can adjust the first clamping member 31 and the second clamping member 32 at the same time to shorten the adjustment time required for the first clamping member 31 and the second clamping member 32 to fix the detection component 1 on the mounting frame 221.

[0053] The sliding process of the first clamping member 31 and the second clamping member 32 can be achieved by manual adjustment or by an external driving device. For example, an adjusting nut can be connected to the first clamping member 31, and the first clamping member 31 and the second clamping member 32 can be connected by a fixing rod. The adjusting nut is electrically connected to a motor. When the motor rotates forward, the first clamping member 31 and the second clamping member 32 can move closer to each other to clamp the detection component 1 to the mounting frame 221. When the motor rotates in reverse, the first clamping member 31 and the second clamping member 32 can move away from each other to release the detection component 1 from the mounting frame 221, making it convenient for the operator to replace the detection component 1. Alternatively, adjusting nuts can be provided on both the first clamping member 31 and the second clamping member 32, and the adjusting nuts are electrically connected to a motor. Both the first clamping member 31 and the second clamping member 32 can slide on the mounting frame 221, thus shortening the position adjustment time of the first clamping member 31 and the second clamping member 32.

[0054] In other embodiments, the first clamping member 31 and the second clamping member 32 may also be hinged to the mounting frame 221 respectively. The first clamping member 31 and the second clamping member 32 are disposed on both sides of the detection component 1. When rotating in the direction close to the detection component 1, the first clamping member 31 and the second clamping member 32 can clamp the detection component 1 to the mounting frame 221. When rotating in the direction away from the detection component 1, the first clamping member 31 and the second clamping member 32 can release the detection component 1 from the mounting frame 221.

[0055] The shapes of the clamping surfaces of the first clamping member 31 and the second clamping member 32 are adapted to the shape of the detection component 1 to improve the clamping effect of the first clamping member 31 and the second clamping member 32 on the detection component 1 and prevent the detection component 1 from shifting or loosening during the clamping process. To improve the clamping effect of the first clamping member 31 and the second clamping member 32 on the detection component 1, an anti-slip pad or an anti-slip corrugated surface can be provided on the side of the first clamping member 31 and the second clamping member 32 near the detection component 1.

[0056] To enhance the fixation of the detection component 1 by the first clamping member 31 and the second clamping member 32, multiple mounting brackets 221 can be provided along the axial direction of the detection component 1, and clamping components 3 can be correspondingly provided on the mounting brackets 221. In this embodiment, to improve the sliding stability of the first clamping member 31 and the second clamping member 32 on the mounting bracket 221, through grooves in the horizontal direction are provided at both ends of the first clamping member 31 and the second clamping member 32, and the mounting bracket 221 passes through the through grooves to ensure that the first clamping member 31 and the second clamping member 32 can slide smoothly along the mounting bracket 221.

[0057] To improve the positioning effect of the detection component 1, in this embodiment, the mounting frame 221 is provided with a positioning member 2211, which is engaged with the first clamping member 31 and the second clamping member 32 respectively. The positioning member 2211 is set at a preset position on the mounting frame 221. When the first clamping member 31 and the second clamping member 32 are engaged with the positioning member 2211, the detection component 1 can be clamped in the preset position. When the detection component 1 is in the preset position, its two ends are exactly aligned with the openings of the air inlet pipe 9 and the exhaust pipe 10, which facilitates the detection component 1 to perform gas emission detection. The positioning member 2211 provides a clear positioning for the first clamping member 31 and the second clamping member 32, ensuring the normal detection process of the detection component 1. In this embodiment, the preset position of the positioning member 2211 is the middle position of the mounting frame 221. The positioning member 2211 is a limiting protrusion, and both the first clamping member 31 and the second clamping member 32 have slots that cooperate with the limiting protrusion. Specifically, in order to adapt to detection components 1 of different sizes, various positioning parts 2211 of different sizes that can be installed on the mounting bracket 221 can be prepared in advance.

[0058] like Figure 3As shown, the gas emission detection device may further include a first locking member 4 and a second locking member 5. The mounting frame 221 has multiple first locking holes and multiple second locking holes spaced apart along its length. The first locking member 4 is detachably inserted through any of the first locking holes, enabling the first clamping member 31 to be locked to the mounting frame 221. The second locking member 5 is detachably inserted through any of the second locking holes, enabling the second clamping member 32 to be locked to the mounting frame 221. The multiple first locking holes and multiple second locking holes allow the locking positions of the first clamping member 31 and the second clamping member 32 on the mounting frame 221 to be adjustable, adapting to detection components 1 of different sizes and providing a better clamping and fixing effect for the detection components 1. The first locking member 4 and the second locking member 5 can be pins or bolts; no further limitations are made here.

[0059] In this embodiment, when the first clamping member 31 and the second clamping member 32 are slid to clamp the detection component 1 and snapped into the positioning member 2211, the first locking member 4 is used to fix the first clamping member 31 to the mounting bracket 221, and the second locking member 5 is used to fix the second clamping member 32 to the mounting bracket 221. This can improve the clamping effect on the detection component 1. When the protective door 22 switches between the working position and the maintenance position, the first clamping member 31 and the second clamping member 32 can always clamp the detection component 1, thereby enhancing the safety of the detection component 1 during movement.

[0060] To ensure the smooth operation of the detection component 1 during normal detection, the gas emission detection device may further include a third locking element 8. One end of the third locking element 8 passes through the protective door 22 and enters the housing 21, while the other end presses against the protective door 22 to lock the protective door 22 in the working position. The third locking element 8 prevents the mounting bracket 221 from continuing to move away from the housing 21 due to accidental machine contact or improper operation after the protective door 22 has reached the working position. In this embodiment, multiple fixing blocks 213 are provided on the side of the housing 21 near the protective door 22, and the third locking element 8 can pass through the protective door 22 into the fixing blocks 213. The third locking element 8 can be a bolt or a pin, etc.

[0061] Due to manufacturing factors, when the protective door 22 is in the working position, it may not be completely sealed to the housing 21. To prevent external dust or air from entering the housing 21 and affecting the detection process of the detection component 1, a seal can be installed on the side of the protective door 22 closest to the housing 21. This improves the sealing effect between the protective door 22 and the housing 21 when the protective door 22 is in the working position, ensuring that the detection space enclosed by the protective door 22 and the housing 21 is completely isolated from the external space, thus improving the accuracy of the detection results. The seal can be a sealing strip or a sealing gasket, etc.

[0062] In this embodiment, the gas emission detection device further includes a suction member 6, which is located inside the housing 21. The suction member 6 can transport the gas to be tested to the detection component 1. The suction member 6 can enhance the flow efficiency of the gas to be tested, thereby improving the detection efficiency of the detection component 1. The suction member 6 can be a fan.

[0063] The gas emission detection device in this embodiment also includes a protective component 7, which includes a protective housing 71, a first filter 72, and a second filter 73. The protective housing 71 is movably connected to the housing 21. An air inlet is located on the side of the protective housing 71 away from the detection component 1, and an air outlet is located on the side closer to the detection component 1. The first filter 72 is detachably installed at the air inlet, and the second filter 73 is detachably installed at the air outlet. A suction component 6 is installed inside the protective housing 71, capable of drawing the gas to be tested in through the air inlet and delivering it to the detection component 1 through the air outlet. The protective housing 71, the first filter 72, and the second filter 73 effectively block large particles of dust or contaminants carried by the gas to be tested, preventing the suction component 6 from contacting impurities and ensuring the long-term reliable operation of the suction component 6. It is understood that when the protective door 22 is in the working position, the suction component 6 operates normally, delivering the gas to be tested from the air inlet pipe 9 through the air inlet and air outlet to the detection component 1. When the protective door 22 is under maintenance, the suction unit 6 stops operating, halting the suction process of the gas to be tested, ensuring the safety of maintenance personnel. The first filter element 72 and the second filter element 73 can be filter screens. In this embodiment, both the first filter element 72 and the second filter element 73 are connected to the protective housing 71 by bolts.

[0064] Specifically, the protective housing 71 is hinged or slidably connected to the housing 21. When the protective housing 71 is hinged to the housing 21, rotating the protective housing 71 upwards allows the second filter element 73 to face the opening of the housing 21, facilitating the operator's inspection of the suction component 6 and cleaning or replacing the second filter element 73. Rotating the protective housing 71 until its air inlet and air inlet pipe 9 are connected facilitates the operator's cleaning or replacement of the first filter element 72.

[0065] When the protective housing 71 is slidably connected to the housing 21, the process of the protective housing 71 sliding into and out of the housing 21 enables the switching between normal operation and maintenance of the first filter element 72, the second filter element 73, and the suction element 6. It is understood that the aforementioned maintenance process is carried out after the protective door 22 has switched to the maintenance state and the suction element 6 has stopped normal operation.

[0066] To facilitate the operation of the protective housing 71 by the operator, an operation hole 711 can be provided on the side of the protective housing 71 near the detection component 1, providing a force point for the operator and improving the convenience of operation.

[0067] In this embodiment, the detection component 1 includes a first guide port 11, a detection chamber 12, and a second guide port 13 connected in sequence. When the protective door 22 is in the working position, the first guide port 11 can be connected to the air inlet pipe 9, and the second guide port 13 can be connected to the exhaust pipe 10. Along the flow direction of the gas to be tested, the cross-sectional size of the first guide port 11 gradually decreases, and the cross-sectional size of the second guide port 13 gradually increases. The flow direction of the gas to be tested refers to the direction in which the gas to be tested flows from the air inlet pipe 9 to the exhaust pipe 10. In this embodiment, the flow direction of the gas to be tested is from bottom to top. Setting the first guide port 11 and the second guide port 13 can improve the efficiency of the gas to be tested entering and exiting the detection chamber 12, thereby improving the detection efficiency of the detection component 1.

[0068] In this embodiment, as Figure 3 and Figure 4 As shown, a limiting part 212 is provided on the upper part of the housing 21. When the protective door 22 is in the working position, the second guide port 13 and the limiting part 212 are in contact to prevent the gas to be tested passing through the second guide port 13 from contacting the inner wall of the housing 21. The limiting part 212 can prevent the gas to be tested from leaking into the housing 21 and limit the impurities in the gas to be tested from adhering to the inside of the housing 21, thereby reducing the cleaning burden.
