Description

Technical Field

[0001] This utility model relates to the field of detector technology, and in particular to a modular structure gas detector. Background Technology

[0002] With the continuous expansion of industrial production and the accelerated pace of urbanization, the application and emission of various gases in industrial manufacturing, energy development, environmental monitoring, and public safety are becoming increasingly complex. Gas leaks and pollution not only lead to equipment damage and production interruptions, but can also trigger serious safety accidents such as fires, explosions, and poisoning, threatening human life, health, and property safety. Traditional gas detectors have limited functionality and fixed structures, making it difficult to meet diverse detection needs in different detection scenarios and complex environments with mixed gases. Furthermore, when some functions of the detector malfunction, the entire device often needs to be returned to the factory for repair, resulting in high maintenance costs and long cycles, severely impacting operational efficiency. Against this backdrop, modular gas detectors have emerged. With their advantages of flexible combination, convenient maintenance, and efficient adaptability, they have become an important direction for solving current gas detection challenges, providing more reliable and intelligent technical support for gas detection and safety protection in various industries.

[0003] In practical applications, existing gas detectors suffer from significant performance and lifespan limitations due to deficiencies in sensor replacement and heat dissipation design. On one hand, gas sensors, as core detection components, are often fixed using welding or complex screws. Replacement requires specialized tools and can easily damage circuit boards and other components, making the process cumbersome, time-consuming, and labor-intensive, while also increasing maintenance costs and complexity. On the other hand, during operation, the gas sensor and internal electronic components continuously generate heat. The lack of an efficient heat dissipation structure hinders rapid heat dissipation, leading to elevated internal temperatures. This affects sensor accuracy and stability, shortens lifespan, and may even cause equipment malfunctions, failing to meet the high reliability and stability requirements of gas detectors in industrial production and environmental monitoring scenarios.

[0004] Therefore, those skilled in the art have provided a modular gas detector to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular gas detector. The assembly mechanism allows for convenient assembly, use, disassembly, and maintenance of the gas sensor, facilitating easy replacement. Furthermore, the heat dissipation mechanism enables rapid heat dissipation from the detector body, preventing damage to internal components due to heat buildup.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A modular gas detector includes a detector body and a gas sensor, with an assembly mechanism provided between the detector body and the gas sensor, and a heat dissipation mechanism fixedly connected to the rear end face of the detector body.

[0008] The assembly mechanism includes an upper fixing ring and a lower fixing ring. The upper fixing ring is fixedly connected to the lower end face of the detector body, and the lower fixing ring is fixedly connected to the upper end face of the gas sensor. Fixing grooves are provided on both sides and at the front and rear of the lower end face of the upper fixing ring. A limiting hole is provided on one side of the inner wall of each of the fixing grooves. Adjusting grooves are provided on both sides and at the front and rear of the upper end face of the lower fixing ring. A return spring is fixedly connected to one side of the inner wall of each of the adjusting grooves. A connecting plate is fixedly connected to the other end of each of the return springs. A limiting post is fixedly connected to one side of each of the connecting plates. The limiting post is engaged in the limiting hole.

[0009] With the above technical solution, the connecting plate moves, the return spring is compressed and the limiting column moves synchronously, and the limiting column is sleeved in the fixed groove. Then the return spring pops out and pushes the connecting plate to move. The limiting column is synchronously and locked in the limiting hole. The upper fixed ring and the lower fixed ring are fixedly connected, which allows the gas sensor to be assembled and used.

[0010] Furthermore, the heat dissipation mechanism includes a heat dissipation frame, which is fixedly connected to the rear end face of the detector body. A heat-conducting plate is fixedly sleeved on the front end face of the heat dissipation frame, and a plurality of heat transfer columns are fixedly connected to the rear end face of the heat-conducting plate. A heat collection column is fixedly connected between the upper and lower inner walls of the heat dissipation frame, and the plurality of heat transfer columns are fixedly connected to the heat collection column. A spiral blade is fixedly sleeved on the outer wall of the heat collection column.

[0011] Through the above technical solution, the heat generated by the detector body is transferred to the heat collection column through the heat conduction plate and heat transfer column. Under the action of the spiral blades, air convection is enhanced. At the same time, the spiral blades increase the heat exchange area, which can quickly and efficiently dissipate the heat, effectively reduce the temperature of the detector, and ensure its stable operation.

[0012] Furthermore, an air inlet is provided on the lower part of one side of the outer wall of the heat dissipation frame, and an air outlet frame is fixedly fitted on the upper part of the other side of the outer wall of the heat dissipation frame.

[0013] The above technical solution, through the design of the air inlet and outlet frame, can achieve better air circulation.

[0014] Furthermore, a mounting column is fixedly connected to one side of the inner wall between the upper and lower ends of the air outlet frame, a drive motor is fixedly connected to one side of the mounting column, a cooling fan is fixedly connected to the output end of the drive motor, and dust filters are fixedly fitted inside both the air inlet and the air outlet frame.

[0015] The above technical solution uses a drive motor to power a cooling fan, thereby increasing airflow speed and quickly dissipating heat. The dust filter prevents dust from entering and damaging the equipment.

[0016] Furthermore, a sealing ring is fixedly sleeved inside the upper fixing ring, and the sealing ring is movably sleeved inside the lower fixing ring;

[0017] The above technical solution, through the use of a sealing ring, can achieve a better sealing effect.

[0018] Furthermore, each of the multiple adjustment slots has a movable hole on one side of its inner wall, and a push rod is movably fitted in each of the multiple movable holes. The push rod is fixedly connected to the connecting plate, and a push head is fixedly connected to the other end of the push rod.

[0019] The above technical solution allows for the control of the movement of the connecting plate by using a pusher and a push rod.

[0020] Furthermore, buffer grooves are provided on the inner walls of the upper and lower ends of the movable hole, and limit slide rods are fixedly connected between the inner walls of the two buffer grooves. Movable sleeves are movably sleeved on the outer walls of the two limit slide rods, and the movable sleeves are fixedly connected to the push rod.

[0021] The above technical solution allows for better limiting of the push rod's movement by using a movable sleeve.

[0022] Furthermore, mounting covers are fixedly connected to the upper end face and the outer walls of both sides of the detector body, and mounting holes are opened on the front end face of multiple mounting covers. Cable inlet sockets and audible and visual alarms are fixedly connected to both sides of the detector body, and an external threaded mounting ring is fixedly connected to the lower end face of the gas sensor.

[0023] The above technical solution allows for convenient installation and fixation of the equipment via the mounting cover, better usability via the cable inlet and audible / visual alarm, and the external threaded mounting ring enables assembly and detection.

[0024] This utility model has the following beneficial effects:

[0025] 1. The modular gas detector proposed in this utility model allows for convenient replacement of the gas sensor during assembly. Pushing the pusher head moves the push rod, causing the connecting plate to move synchronously. The return spring compresses, and the limiting post moves synchronously, fitting the limiting post into the fixing groove. Releasing the pusher head then releases the return spring, which in turn pushes the connecting plate to move. The limiting post is then synchronously and engaged in the limiting hole. The upper and lower fixing rings are fixedly connected, allowing the gas sensor to be assembled and used. When it needs to be removed, simply press the pusher head again, thus achieving convenient replacement of the gas sensor and improving its usability.

[0026] 2. The modular structure gas detector proposed in this utility model transfers the heat generated by the detector body to the heat collection column through the heat conduction plate and heat transfer column. The spiral blades on the heat collection column enhance air convection under the action of the cooling fan driven by the drive motor. At the same time, the spiral blades increase the heat exchange area, quickly and efficiently dissipating heat from the air outlet frame, effectively reducing the detector temperature, ensuring its stable operation, and having better usability and stability.

[0027] 3. The modular gas detector proposed in this utility model allows for convenient assembly, use, disassembly, and maintenance of the gas sensor through the set assembly mechanism, which has the advantage of convenient replacement. In addition, the set heat dissipation mechanism can quickly dissipate the heat generated by the detector body, thereby avoiding the problem of damage to the internal components of the detector body due to heat accumulation.
