Description

Technical Field

[0001] This utility model relates to the field of safety detection technology, and in particular to a fire alarm detection device for carding dust removal pipelines. Background Technology

[0002] During the high-speed carding process, carding machines generate a large amount of dust, short fibers, and other impurities. If these impurities are not removed in time, they will pollute the workshop air, affect workers' health, and reduce product quality. The main function of carding dust removal pipes is to promptly suck up these impurities and transport them to dust removal equipment for treatment, thereby purifying the workshop air and ensuring smooth production.

[0003] Currently, the carding dust removal pipes are not equipped with fire alarm systems when they leave the factory. If the carding machine cover plate is not cleaned in time, or if the cylinder cover cloth reaches the end of its service life and is not replaced, or if the distance between the cylinder and the cover plate becomes smaller, it is very easy to generate sparks, which can ignite the fallen cotton. The fallen cotton with sparks reaches the presser through the conveying pipe, which can ignite the cotton inside the presser and cause a fire.

[0004] In addition, some users may install fire detection devices themselves, but this is usually very troublesome. For example, installing them with screws inside pipes can cause problems such as inconvenient signal transmission (wireless transmission is easily isolated), the detector is easily interfered with by impurities, and disassembly and assembly are inconvenient.

[0005] Therefore, the applicant proposed a fire alarm detection device for carding dust removal pipes that can accurately detect fires and is easy to disassemble and install, as a solution. Utility Model Content

[0007] To solve the above-mentioned technical problems, the present invention provides a fire alarm detection device for a carding dust removal pipeline, comprising a pipeline body, a threaded hole on the side wall of the pipeline body, and a detection component threadedly connected to the threaded hole. The detection component includes a threaded cylinder threadedly connected to the threaded hole, a disc mounted on the top of the threaded cylinder, and a detector mounted both inside the threaded cylinder and in a recess at the bottom of the disc. The probe head at the bottom of the detector passes through the bottom of the threaded cylinder and is located inside the pipeline body. The data interface at the top of the detector is located at the top of the disc and is connected to a data cable. The other end of the data cable is connected to a control alarm module. A limit component is installed on the pipeline body to limit the horizontal position of the disc.

[0008] Preferably, the outer wall of the pipe body is provided with a threaded groove around the threaded hole, and the threaded cylinder is also threadedly connected to the inner thread of the threaded groove, and the rubber ring fixed at the top of the threaded groove contacts the bottom of the disc.

[0009] Preferably, the inner wall of the pipe body is provided with a second threaded groove around the threaded hole, and the threaded cylinder is also threadedly connected to the inner thread of the second threaded groove. A transparent cover is installed at the bottom of the second threaded groove, and the probe head is covered inside.

[0010] Preferably, the top of the disk has a threaded groove three fixed around the data interface, and a gland waterproof head is threaded onto the threaded groove three. The upper end of the gland waterproof head is through which the data cable passes to form a sealed sliding connection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-6 As shown, the present invention includes a pipe body 1, the side wall of the pipe body 1 is provided with a threaded hole, and a detection component 2 is threadedly connected in the threaded hole;

[0024] The detection component 2 includes a threaded cylinder 22 threaded into a threaded hole. A disc 21 is mounted on the top of the threaded cylinder 22, and a detector 23 is mounted inside the threaded cylinder 22 and in the recess at the bottom of the disc 21. The probe 24 at the bottom of the detector 23 passes through the bottom of the threaded cylinder 22 and is located inside the pipe body 1. The detector 23 can be designed as an integrated temperature and light sensor. The data interface at the top of the detector 23 is located at the top of the disc 21 and is connected to a data cable 210. The other end of the data cable 210 is connected to a control alarm module 3. The control alarm module 3 has a microcontroller inside, which can convert the light (or temperature) detection signal into an electrical signal. A limit component 4 is installed on the pipe body 1 to limit the horizontal position of the disc 21.

[0025] As described above, through the design of the detection component 2, the pipe body 1 is pre-threaded with a groove at the factory. During installation, the threaded cylinder 22 is screwed into the threaded hole on the side wall of the pipe body 1 until the disc 21 reaches the appropriate position. At this time, the probe head 24 at the bottom of the detector 23 extends into the interior of the pipe body 1 and can directly contact the environment inside the pipe. Subsequently, the horizontal position of the disc 21 is limited by the limiting component 4 to prevent the disc 21 from rotating and ensure that the probe head 24 is always in a stable detection position. During operation, the detector 23 can act as an integrated temperature and light sensor to continuously monitor the environment inside the pipe body 1. When the temperature inside the pipe rises abnormally due to the accumulation of cotton fibers, frictional heat, or other reasons, or when abnormal light sources such as flames appear, the detector 23 will quickly capture these changes. The temperature sensing element integrated inside the detector 23... The detector 23 and the photosensitive element convert the temperature and light signals into electrical signals, respectively. These electrical signals are then transmitted to the data interface on top of the detector 23. The data cable 210 connects the data interface to the control alarm module 3, enabling the electrical signals to be transmitted to the control alarm module 3 in real time. After receiving the electrical signals, the microcontroller inside the control alarm module 3 immediately performs high-speed calculations and analysis. Based on preset algorithms and thresholds, the microcontroller determines whether a fire has occurred in the pipeline. Once the microcontroller confirms a fire in the pipeline, it quickly outputs a relay signal. This signal triggers the audible and visual alarm device on the control alarm module 3, emitting a loud alarm sound and a conspicuous flashing light to remind on-site personnel to take timely countermeasures. At the same time, the relay signal also cuts off the control signal of the cleaning system cabinet, causing the cleaning system and dust removal system to stop immediately. This design effectively prevents the further spread and expansion of the fire, protecting the safety of equipment and personnel.

[0026] Meanwhile, this device is easy to assemble and disassemble and is convenient to maintain. It can be disassembled by rotating it in the opposite direction. Note that the limit component 4 should be released beforehand. At the same time, the design of the data cable 210 makes it easy to connect it to the control alarm module 3. The detector 23 is located on the threaded cylinder 22 for protection.

[0027] The electronic devices used above are all existing technologies, so their detailed structures and working principles will not be described in detail.

[0028] The outer wall of the pipe body 1 has a threaded groove 25 around the threaded hole. The threaded cylinder 22 is also threadedly connected to the inner thread of the threaded groove 25. The rubber ring 26 fixed at the top of the threaded groove 25 contacts the bottom of the disc 21. The inner wall of the pipe body 1 has a threaded groove 27 around the threaded hole. The threaded cylinder 22 is also threadedly connected to the inner thread of the threaded groove 27. A transparent cover 28 is installed at the bottom of the threaded groove 27, and the probe 24 is covered inside.

[0029] Furthermore, through the design of threaded groove 1 25 and threaded groove 27, the rubber ring 26 at the top of threaded groove 1 25 strengthens the seal and has a limiting function, preventing the disc 21 from moving down, while the transparent cover 28 at the top of threaded groove 27 can protect the probe head 24 and prevent impurities from sticking to the probe head 24.

[0030] The top of the disk 21 has a threaded groove 211 fixed around the data interface. A gland waterproof head 29 is threaded onto the threaded groove 211. The upper end of the gland waterproof head 29 is passed through by the data cable 210 to form a sealed sliding connection.

[0031] Furthermore, the Gran Waterproof Connector 29 can provide additional dust and water protection to the wiring points, ensuring the stability of the device's operation.

[0032] The limiting component 4 includes a hollow box 41 fixed to the pipe body 1. A slider 42 slides inside the hollow box 41. An L-shaped rod 43 passing through the hollow box 41 is fixed to one side of the slider 42. The upper end of the L-shaped rod 43 is inserted into the side socket of the disc 21. A guide rod 44 is fixed to one side of the slider 42 and passes through the other end of the hollow box 41. A spring 45 sleeved on the outside of the guide rod 44 is connected between the slider 42 and the hollow box 41. A ring 46 is rotatably installed on the outer end of the guide rod 44. A locking rod 47 is fixed to one side of the outer wall of the pipe body 1. The locking rod 47 is provided with a locking slot for the ring 46 to be inserted.

[0033] Furthermore, the operation of the limiting component 4 is described in detail. During installation, the outer ring 46 is pulled into the slot on the locking rod 47. After installation, the side insertion port of the disc corresponds to the upper end of the L-shaped rod 43. At this time, the outer ring 46 is released. Under the action of the spring 45, the guide rod 44 drives the slider 42 to slide towards the disc 21. The movement of the slider 42 causes the L-shaped rod 43 to move synchronously. The upper end of the L-shaped rod 43 is precisely inserted into the side insertion port of the disc 21, thereby effectively limiting the horizontal position of the disc 21 and preventing the detection component 2 from rotating due to external factors. This ensures the stability of the position of the probe 24 within the pipe body 1 and ensures that the detection work can be carried out continuously and accurately. When it is necessary to disassemble the detection component 2 for maintenance or replacement, the outer ring 46 is pulled out again to allow the L-shaped rod 43 to exit from the side insertion port of the disc 21, and the detection component 2 can be easily removed.

[0034] All structures in this case can be factory-configured, making overall installation convenient and quick. The detection is accurate, enabling timely detection and alarm shutdown, thus reducing the fire's spread, buying time for timely firefighting, and minimizing economic losses.

[0035] Working principle: During operation, the threaded cylinder 22 of the detection component 2 is screwed into the threaded hole on the side wall of the pipe body 1. Due to the design of the thread groove 1 25 and the thread groove 27, the threaded cylinder 22 is tightly connected to the two. The rubber ring 26 strengthens the seal and limits the disc 21. The transparent cover 28 protects the detection head 24. Before installation, the outer pull ring 46 is inserted into the locking rod 47. After installation, the side insertion port of the disc 21 corresponds to the L-shaped rod 43. The ring 46 is released, and the spring 45 pushes the slider 42, so that the L-shaped rod 43 is inserted into the insertion port, fixing the disc 21. The detector 23, as an integrated temperature and light sensor in the prior art, continuously monitors the environment inside the pipe. When the temperature is abnormal or a fire occurs, its internal components convert the signal into an electrical signal, which is transmitted to the control alarm module 3 via the data line 210. After analysis and judgment by the microcontroller, if a fire is confirmed, an audible and visual alarm is triggered and the cotton cleaning and dust removal system signals are cut off to achieve shutdown protection. The grate waterproof head 29 is dustproof and waterproof at the connection point to ensure stable operation of the device.
