Description

Technical Field

[0001] The present invention belongs to the technical field of detectors, and more specifically, particularly relates to an adjustable carbon monoxide detector. Background Art

[0002] Carbon monoxide is a colorless, tasteless, odorless toxic gas. Long-term inhalation can easily lead to hypoxia in the human body, which can be life-threatening in severe cases. A large amount of carbon monoxide is often produced during industrial combustion. If relevant protective measures are not in place, it is easy to cause a large amount of carbon monoxide to escape. The escape of carbon monoxide is difficult to detect, which will bring certain safety hazards to the surrounding environment and personnel. In order to ensure the safety of personnel, carbon monoxide detectors are often required.

[0003] A carbon monoxide detector is a device that can continuously detect the concentration of carbon monoxide gas. It can always detect the concentration of carbon monoxide in the surrounding environment. When the concentration is too high, it can give timely feedback to remind people to take prompt measures to avoid poisoning accidents. However, during the detection process, traditional carbon monoxide detectors can often only monitor a single height of the space and cannot adjust the height according to the use environment. When in large factory workshops or storage warehouses, there are usually large spaces with complex internal air flow. Traditional detectors may not be able to fully and accurately monitor the changes in carbon monoxide concentrations in spaces at different heights, resulting in potential dangers in certain areas being ignored. Once the carbon monoxide concentration exceeds the standard at an undetected height, and the staff fails to detect it in time, it will bring greater safety risks. At the same time, it also limits the use environment of the detector and reduces the applicability of the detector. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an adjustable carbon monoxide detector to solve the technical problem in the prior art that traditional detectors are unable to monitor the changes in carbon monoxide concentration in spaces at different heights, which easily leads to the neglect of carbon monoxide concentrations at different heights, causing greater safety hazards and reducing the applicability of the detector.

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

[0017] 1.

This allows the support plate to move up and down stably and orderly on the main frame according to the established track. A connecting wheel is arranged at one end of the screw rod, and the two sets of connecting wheels are connected by a transmission belt, ensuring that the two sets of screw rods can achieve synchronous rotation, thereby ensuring the stability and consistency of the support plate during the up and down movement. In addition, a mounting plate is arranged on one side of the main frame, and the second motor is mounted on it. The shaft end of the second motor is connected to one set of connecting wheels. Through the control of the second motor, the screw rod can be driven to rotate, so that the support plate can adjust the height in the vertical direction, and the carbon monoxide concentration at different heights can be detected, reducing the risk of carbon monoxide concentration being ignored. The carbon monoxide concentration in each height space can be accurately monitored, thereby improving the safety level in the warehouse.

[0018] 2. The support plate and the rotating seat are rotatably connected, and the detection assembly is installed on the rotating seat. A first motor is installed at the bottom of the support plate, and the shaft end of the first motor is connected to the rotating seat, and the rotation of the rotating seat can be driven by the first motor. When the first motor is started, the power generated by it can be effectively transmitted to the rotating seat, causing the rotating seat to rotate in a preset direction and speed. As the rotating seat rotates, the detection assembly connected to it is directly driven to change the detection direction, achieving more comprehensive and accurate monitoring. This ensures that under any complex environmental conditions, there will be no monitoring blind spots and missed areas, improves the reliability and effectiveness of monitoring, and provides a strong guarantee for timely detection and handling of abnormal carbon monoxide concentrations.

[0019] 3. A sealed tank is provided in the detection component, and the sealed tank is connected to the vent pipe on the shell to form a coherent gas passage. A fan is provided inside the air inlet. When the fan is running, it can forcefully blow the outside air into the sealed tank. The sealed tank itself has a narrow internal space, and the probe of the carbon monoxide sensor is inserted into the sealed tank. The narrow space can provide a more concentrated and stable gas environment, which is convenient for the carbon monoxide sensor to detect, greatly improving the accuracy and sensitivity of the detection. It can effectively separate carbon monoxide from other gas components. Because carbon monoxide has certain chemical activity, if it comes into direct contact with other gas components, it may corrode them or interfere with their normal operation. The existence of the sealed tank forms an effective barrier to prevent carbon monoxide from causing any adverse effects on other components, thereby ensuring the long-term stable operation and reliability of the entire detection component. In the detection component, the wireless module in the control box can be connected to the external alarm system to achieve real-time remote monitoring and alarm, and promptly notify relevant personnel to take measures. At the same time, when the detector is not in use, the support plate is moved into the protective box, and the protective plate on the support plate contacts the protective box to form a protective cavity. The detection component is located in the protective cavity, which provides good physical protection for the detection component, reduces damage to the detector by external factors, and ensures that it can still work stably in harsh environments. In addition, there are an oil storage cavity and an oil outlet on the support plate, and a three-way pipe is arranged on the support plate. The three-way pipe is connected to the oil storage cavity through a connecting pipe, so that the lubricating oil can be injected in and out through the three-way pipe, and then flows out from the oil outlet and smeared on the screw rod and the sliding rod, which helps to reduce friction, ensure the smoothness of sliding, and further improve the stability and reliability of the detector.

Four groups of connecting plates 12 are arranged on both sides of the main frame 11, and the connecting plates 12 are symmetrically distributed. Two groups of connecting plates 12 are provided with bearings, and screw rods 31 and sliding rods 32 are arranged on both sides of the main frame 11. The two ends of the screw rod 31 are respectively inserted into the bearings, so that the screw rod 31 can achieve stable and efficient rotation with the assistance of the bearings. The sliding rod 32 is inserted on the other two groups of connecting plates 12, providing a stable guiding effect for the whole structure. Both ends of the support plate 21 are sleeved on the screw rod 31 and the sliding rod 32, ensuring the sliding connection between the support plate 21 and the main frame 11. When the screw rod 31 rotates, due to the matching relationship between it and the support plate 21, the support plate 21 can slide on the main frame 11 along the guidance of the sliding rod 32. A rotating seat 22 is arranged above the support plate 21, and the rotating seat 22 and the support plate 21 are rotatably connected, so that the rotating seat 22 can rotate relative to the support plate 21, which not only ensures the smoothness of rotation, but also maintains stability and reliability under various working conditions. A detection component is also arranged above the support plate 21, and the carbon monoxide concentration is monitored by the detection component. The detection component is connected to the rotating seat 22, which not only ensures the stability of the detection component during the working process, but also can adjust the detection direction with the help of the rotation function of the rotating seat 22, so as to better adapt to different working scenes and detection needs.

[0039] like Figure 6 , Figure 7 , Fig.10As shown, the detection assembly consists of a shell 401 and a sealed tank 402, and the shell 401 is detachably connected to the rotating seat 22. A cover plate 403 is also detachably provided on the top of the shell 401. When the cover plate 403 is connected to the shell 401, an installation cavity is formed, and the installation cavity provides a stable and safe working environment for the internal components. Ventilation pipes 404 are provided at both ends of the shell 401, and one end of one group of ventilating pipes 404 is provided with an air inlet 405, and a fan 406 is provided inside the air inlet 405. The fan 406 can effectively inhale the outside air and provide sufficient gas samples for subsequent detection work. An outlet 407 is provided at one end of the other group of ventilating pipes 404 for discharging the detected gas to form a complete gas circulation channel. The sealed tank 402 is installed in the installation cavity and is clamped between the two groups of ventilating pipes 404 to ensure the sealing and stability of the gas during the transmission process. Through holes 408 are provided at both ends of the sealed tank 402, and an extension tube 409 is provided in the ventilation tube 404. The extension tube 409 is inserted in the through hole 408, which effectively ensures the smooth transmission of gas.

[0040] The extension tube 409 is provided with a limiting slot 412, and the vent tube 404 is provided with a limiting slot 413 corresponding to the limiting slot 412. The pressing plate 414 can pass through the limiting slot 413 and be clamped in the limiting slot 412, so that the extension tube 409 and the vent tube 404 are slidably connected. It can not only meet different installation and use requirements, but also be adjusted when necessary. Positioning columns 415 are provided on both sides of the vent tube 404, and the positioning columns 415 can be inserted into the positioning plate 410, further enhancing the stability of the structure. A first spring is also provided between the positioning plate 410 and the vent tube 404, and the first spring is sleeved on the positioning column 415. The presence of the first spring can provide elastic support, which supports the extension tube 409, so that the extension tube 409 is inserted into the through hole 408.

[0041] The detection assembly also includes a carbon monoxide sensor 416 and a control box 417, both of which are installed in the installation cavity to ensure that they are in a stable environment. The carbon monoxide sensor 416 probe is inserted into the sealed can 402, so that the sensor can sense the change in carbon monoxide concentration in the sealed can 402, thereby providing accurate and timely detection data. The control box 417 is composed of a box body, a control panel 418 and a wireless module 419. The box body provides protection for the internal components, the control panel 418 is responsible for processing and analyzing the detection signal from the carbon monoxide sensor 416, and the wireless module 419 undertakes the key task of establishing a communication connection with the external alarm system. The carbon monoxide sensor 416 is electrically connected to the control box 417 to ensure that the detected data can be quickly and accurately transmitted to the control panel 418 for processing and judgment. Once the control panel 418 analyzes that the carbon monoxide concentration exceeds the safety standard, the wireless module 419 will immediately send an alarm signal to the external alarm system to notify relevant personnel to take emergency measures in time.

[0047] Embodiment 2:

[0048] Based on the adjustable carbon monoxide detector provided in the first embodiment of the present application, the second embodiment of the present application proposes an adjustable carbon monoxide detector. This second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below.

[0049] like Figure 2 , Figure 5 , Fig.11As shown, multiple groups of assembly plates 507 are arranged around the shell 401, and the assembly plates 507 are rotatably connected to the shell 401. Assembly holes 508 are provided on the assembly plates 507 and the rotating seat 22, and the assembly bolts 509 are clamped in the assembly holes 508, which further strengthen the connection between the two and ensure stability under various working conditions; the rotation connection between the assembly plates 507 and the shell 401 can be adjusted according to the use requirements. The assembly plates 507 are unfolded, and the bolts can be passed through the assembly holes 508, and the detection assembly is installed on the wall; the assembly plates 507 are folded, and the assembly bolts 509 are clamped in the assembly holes 508, and the detection assembly is installed on the rotating seat 22. A first motor 510 is arranged at the bottom of the support plate 21, and its shaft end passes through the support plate 21 and is connected to the rotating seat 22.
