Description

Technical Field

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

[0002] In the production of chemical products, many stages generate malodorous gases. For example, in the oil refining process, sulfides in crude oil are converted into hydrogen sulfide and other gases with malodorous odors and released. In the plastics synthesis industry, some monomers such as vinyl chloride or styrene have irritating odors. If these gases leak or are not effectively treated during the production process, they will be released into the air, thus requiring gas detection devices for detection.

[0003] A search revealed Chinese Patent Publication No. CN220932909U, which discloses an odor gas detection device, relating to the technical field of gas detection equipment. The device includes an outer shell and an inner shell threadedly connected to the outer shell. A gas detection component is installed in the inner cavity of the inner shell. The inner shell includes a top cover, a bottom cover, several connecting plates, and at least one mounting plate. The top cover is threadedly connected to the outer shell. The bottom cover, connecting plates, and mounting plate are all located within the inner cavity of the outer shell. Insect-proof filters are fixed between adjacent connecting plates, with the filters spaced apart. The gas detection component is installed on the mounting plate. Several ventilation windows are provided on the outer shell. When the outer shell and inner shell rotate relative to each other, the ventilation windows align with the insect-proof filters or connect the inner cavity of the inner shell to the outside. This utility model can meet the needs of TVOC concentration detection in both outdoor and indoor environments. It eliminates the need for manual handheld detection, has a simple structure, and is easy to install and adjust. However, in actual use, the device isolates flying insects through an insect-proof filter, thereby improving the service life of the detection components. However, the detection range for malodorous gases is relatively low. Malodorous gases can only be effectively detected when they pass through the insect-proof filter, which reduces the detection efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an odor gas detection device, which aims to improve the problem that the existing technology can only effectively detect odor gases when the gas passes through an insect-proof filter, thus reducing the detection efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an odor gas detection device, comprising an odor gas detector, wherein a connecting pipe is connected to the bottom wall of the odor gas detector, a connecting plate is fixedly connected to the outer wall of the connecting pipe, a collection shell is fixedly connected to the outer wall of the connecting plate, a plurality of filter plates are fixedly connected at equal intervals to the outer wall of the collection shell, a servo motor is fixedly connected to the inner bottom wall of the collection shell, a rotating wheel is fixedly connected to the output end of the servo motor, electric push rods are fixedly connected to both the left and right sides of the bottom wall of the connecting plate, a cleaning shell is fixedly connected to the bottom end of the electric push rod, a cleaning sponge ring is fixedly installed on the inner wall of the cleaning shell, an alarm light is fixedly installed on the right side of the odor gas detector, and a fixing mechanism is provided on the rear side of the odor gas detector.

[0006] The above technical solution allows for the following: during testing, the forward-rotating wheel draws air from outside the collection shell, allowing the airflow to pass through multiple filter plates and enter the connecting pipe for detection by the detector, thereby increasing the range of air detection. When the wheel rotates in the opposite direction, it generates an outward-output airflow, which, in conjunction with the raising and lowering of the cleaning shell and cleaning sponge ring, can clean and remove flying particles attached to the outer wall of the collection shell, thus effectively improving the detection efficiency of the equipment.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a fixing plate, the front side of which is fixedly connected to the rear side of the odor gas detector. Two locking plates are rotatably connected to the middle of the rear side of the fixing plate. One side of each locking plate is threaded with a bolt. The left and right sides of the rear side of the fixing plate are provided with engagement grooves. The front end of each engagement groove is threaded with a fixing clamping plate. The front side of each fixing clamping plate engages with the engagement groove. The left and right ends of the front side of the inner wall of the fixing clamping plate are provided with locking grooves. The front sides of the two locking plates engage with the corresponding locking grooves.

[0009] The above technical solution allows the fixing plate to engage with the locking groove, while the locking plate is flipped to lock with the locking groove. Then, the bolts are rotated to fix the fixing plate, avoiding the need to drill holes when fixing the equipment and improving the convenience of installation.

[0010] As a further description of the above technical solution:

[0011] The fixing mechanism also includes two rubber rings, the inner walls of which are respectively fixedly connected to the middle of the bolt.

[0012] The above technical solution enables the rubber ring to reduce the damage to the front side of the inner wall of the fixing plate caused by the bolts, thereby improving the protection effect.

[0013] A control switch is fixedly connected to the bottom left side of the odor gas detector. The control switch is electrically connected to the odor gas detector, the servo motor, and the electric push rod.

[0014] The above technical solution enables the control switch to turn the odor gas detector, servo motor, and electric actuator on and off respectively.

[0015] As a further description of the above technical solution:

[0016] Rubber pads are fixedly connected to the upper and lower sides of the inner wall of the fixed clamping plate, and the inner walls of the multiple rubber pads are all curved.

[0017] The above technical solution improves the fixing effect of the fixing clamp by fixing the rubber pad.

[0018] As a further description of the above technical solution:

[0019] The front of the odor gas detector is fixedly equipped with a protective cover, and the inner wall of the protective cover is fixedly connected with a pressure-resistant glass cover.

[0020] The above technical solution improves the protection of the front side of the instrument panel by connecting the protective cover and the pressure-resistant glass cover.

[0021] As a further description of the above technical solution:

[0022] Multiple support plates are fixedly connected at equal intervals to the outer wall of the connecting pipe, and the bottom walls of the multiple support plates are fixedly connected to the middle of the top wall of the connecting plate.

[0023] The above technical solution improves the protection of the outer wall of the connecting pipe by connecting it with the support plate.

[0024] As a further description of the above technical solution:

[0025] A sealing ring is fixedly connected to the middle of the bottom wall of the connecting plate, and the outer dimensions of the sealing ring are the same as the inner top dimensions of the collecting shell.

[0026] The above technical solution increases the sealing performance at the connection between the collection shell and the connecting plate while the sealing ring is fixed.

[0027] This utility model has the following beneficial effects:

[0028] 1. In this utility model, the servo motor drives the rotating wheel to rotate in either the forward or reverse direction. During testing, air is drawn from outside the collection shell and passes through multiple filter plates into the connecting pipe for detection by the detector. Reverse rotation of the rotating wheel generates outward airflow, which, in conjunction with the lifting and lowering of the cleaning shell, cleans and removes flying particles attached to the outer wall of the collection shell. This effectively improves the detection efficiency of the equipment and ensures long-term performance.

[0029] 2. In this utility model, by engaging the fixed clamping plate with the locking groove, the locking plate is flipped to engage with the fixed clamping plate. By rotating the bolt, the fixed clamping plate is fixed. This eliminates the need to drill holes when fixing the equipment. The fixed clamping plate can be flexibly disassembled after being damaged, which improves the convenience of installation. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an odor gas detection device, comprising an odor gas detector 1, a connecting pipe 3 connected to the bottom wall of the odor gas detector 1, a connecting plate 4 fixedly connected to the outer wall of the connecting pipe 3, and a collection shell 5 fixedly connected to the outer wall of the connecting plate 4. Through the connection of the connecting pipe 3, air entering the collection shell 5 is detected by the odor gas detector 1. Multiple filter plates 6 are fixedly connected at equal intervals to the outer wall of the collection shell 5, and a servo motor 7 is fixedly connected to the inner bottom wall of the collection shell 5. A rotating wheel 8 is fixedly connected to the output end of the servo motor 7. Under the obstruction of the filter plates 6, This allows it to block and filter flying insects and larger particles. At the same time, with the start of the servo motor 7, the wheel 8 completes forward or reverse rotation, achieving the effect of extracting airflow for detection and outputting clean airflow. Electric push rods 9 are fixedly connected to the left and right sides of the bottom wall of the connecting plate 4. A cleaning shell 10 is fixedly connected to the bottom end of the electric push rod 9. A cleaning sponge ring 11 is fixedly installed on the inner wall of the cleaning shell 10. With the start of the electric push rod 9, the cleaning shell 10 drives the cleaning sponge ring 11 to clean the outer wall of the collection shell 5. An alarm light 14 is fixedly installed on the right side of the odor gas detector 1. A fixing mechanism 2 is set on the rear side of the odor gas detector 1.

[0039] Specifically, by activating the servo motor 7, the rotating wheel 8 can rotate forward. The rotating wheel 8 will effectively draw in air from outside the collection shell 5, allowing the airflow to pass through multiple filter plates 6 and enter the interior of the collection shell 5. During this process, larger particles and flying insects in the air will be effectively blocked on the outer wall of the collection shell 5, thus achieving preliminary filtration. The filtered airflow will then pass through the connecting pipe 3 and finally enter the odor gas detector 1 for further detection, thereby expanding the detection range of the airflow and making the detection results more accurate and comprehensive. After the rotating wheel 8 completes its forward rotation... It rotates in the opposite direction, which causes an outward airflow to be generated inside the collection shell 5. This airflow is generated to cooperate with the bottom end of the electric push rod 9 to drive the cleaning shell 10 to rise and fall. Through this rising and falling action, the cleaning sponge ring 11 can complete the cleaning work on the outer wall of the collection shell 5, effectively removing flying insects or particles attached to the outer wall of the collection shell 5, and preventing flying insects or particles from clogging the filter plate 6, thereby affecting the accuracy of detection. This series of cleaning and maintenance measures not only improves the detection efficiency of the equipment, but also ensures the stability and reliability of the equipment during long-term use.

[0040] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 2 includes a fixing plate 201. The front side of the fixing plate 201 is fixedly connected to the rear side of the odor gas detector 1. Two locking plates 202 are rotatably connected to the middle of the rear side of the fixing plate 201. A bolt 203 is threadedly connected to one side of the locking plate 202. By rotating the locking plate 202 and the bolt 203, the locking plate 202 can engage and lock the fixing clamp 205. The bolt 203 further fixes the fixing clamp 205. The left and right sides of the rear side of the fixing plate 201 are provided with engagement grooves 204. The front end of the engagement groove 204 is threadedly connected to the fixing clamp 205. The front side of the fixing clamp 205 engages with the engagement groove 204. The fixing clamp 205 can engage and fix the installation position, avoiding the need for drilling for installation and improving installation efficiency. The left and right ends of the front side of the inner wall of the fixing clamp 205 are provided with locking grooves 206. The front sides of the two locking plates 202 engage with the corresponding locking grooves 206 respectively.

[0041] Specifically, by engaging the fixing clamp 205 with the engaging slot 204, the fixing clamp 205 can be initially fixed to the rear side of the fixing plate 201. Then, with the flipping of the locking plate 202, the front side of the inner wall of the fixing clamp 205 can engage with the locking plate 202. Next, by rotating the bolt 203, the fixing clamp 205 is further secured, avoiding the need for drilling during the equipment fixing process, thus protecting the integrity of the surface of the installation position. In addition, when parts of the fixing clamp 205 are damaged or worn, they can be disassembled and replaced, improving the convenience of installation and maintenance, and making the entire fixing process more efficient and flexible.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The fixing mechanism 2 also includes two rubber rings 208, the inner walls of which are fixedly connected to the middle of the bolts 203 respectively; a control switch 13 is fixedly connected to the bottom left side of the odor gas detector 1, and the control switch 13 is electrically connected to the odor gas detector 1, the servo motor 7 and the electric push rod 9 respectively; rubber pads 207 are fixedly connected to the upper and lower sides of the inner wall of the fixing clamp 205, and the inner walls of the multiple rubber pads 207 are all curved;

[0043] Specifically, the rubber ring 208 reduces the rotational damage of the bolt 203 to the front side of the inner wall of the fixing clamp 205, thereby improving the protection effect of the fixing clamp 205. The control switch 13, which is electrically connected to the odor gas detector 1, the servo motor 7 and the electric push rod 9 respectively, enables the control switch 13 to open and close the device. The rubber pad 207 increases the static friction of the fixing clamp 205, thereby improving the fixing effect.

[0044] Reference Figure 1 , Figure 2 and Figure 4 A protective cover 15 is fixedly installed on the front side of the odor gas detector 1, and a pressure-resistant glass cover 16 is fixedly connected to the inner wall of the protective cover 15; multiple support plates 12 are fixedly connected at equal intervals to the outer wall of the connecting pipe 3, and the bottom walls of the multiple support plates 12 are all fixedly connected to the middle of the top wall of the connecting plate 4; a sealing ring 17 is fixedly connected to the middle of the bottom wall of the connecting plate 4, and the external dimensions of the sealing ring 17 are the same as the internal top dimensions of the collection shell 5.

[0045] Specifically, the protective cover 15 and the pressure-resistant glass cover 16 protect the front of the detector, the support plate 12 improves the protection of the outer wall of the connecting pipe 3, and the sealing ring 17 improves the sealing effect at the connection between the collection shell 5 and the connecting plate 4.

[0046] Working Principle: Upon initial use, the servo motor 7 activates the rotating wheel 8, causing it to rotate forward. During odor gas detection, air outside the collection shell 5 is drawn in, and the airflow passes through multiple filter plates 6 into the collection shell 5. Larger particles and flying insects in the air are blocked on the outer wall of the collection shell 5. The filtered airflow then enters the odor gas detector 1 through the connecting pipe 3 for detection, thus expanding the detection range. After the rotating wheel 8 rotates in the reverse direction, airflow is generated inside the collection shell 5 and output outwards. This, combined with the bottom of the electric push rod 9 driving the cleaning shell 10 to rise and fall, allows the cleaning sponge ring 11 to clean the outer wall of the collection shell 5, thereby removing the odor gas adhering to the surface. The collection of flying insects or particles from the outer wall of the shell 5 for cleaning prevents clogging of the filter plate 6 and thus improves the detection efficiency of the equipment, ensuring long-term performance. Furthermore, the engagement of the fixing clamp 205 with the locking groove 204 initially secures the fixing clamp 205 to the rear side of the fixing plate 201. With the locking plate 202 flipped, it engages with the front inner wall of the fixing clamp 205. Simultaneously, rotating the bolt 203 further secures the clamp 205, eliminating the need for drilling when fixing the equipment. Additionally, the fixing clamp 205 can be disassembled and replaced if damaged, improving installation convenience.
