Description

Technical Field

[0001] This utility model relates to the field of dust detection technology, specifically to an environmental detection device for dust environments. Background Technology

[0002] In dusty environments, environmental monitoring is a core means of assessing the degree of dust pollution and ensuring personnel health and production safety. Concentration detection is the foundation of dust monitoring. Online monitoring devices can monitor continuously in real time without manual sampling and can output concentration data in real time.

[0003] In existing dusty workshops, environmental monitoring devices are limited by location. In scenarios requiring rapid response, laser scattering dust detectors can be used to monitor the environment. However, after long-term operation, the lenses of online monitoring devices are easily contaminated by dust, and the accuracy drifts over long-term use. Utility Model Content

[0004] The purpose of this invention is to provide an environmental monitoring device for dusty environments, which solves the problems mentioned in the background art, such as the lens being easily contaminated by dust and the accuracy drifting after long-term use of online monitoring devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmental detection device for dusty environments, comprising a mobile frame, a dust detection module installed at the upper end of the mobile frame, a wireless transmission module disposed inside the dust detection module, a sleeve installed at the upper end of the dust detection module, lens bodies installed on both sides of the sleeve, an airflow ring fixedly connected to the outside of the lens body, and a plurality of air outlet pipes surrounding the inside of the airflow ring.

[0006] Preferably, the lower end of the mobile frame is equipped with electric wheels, and a battery module is provided below the mobile frame. The battery module is electrically connected to the electric wheels and the dust detection module.

[0007] Preferably, the dust detection module has a signal receiving module installed inside, and a laser emitter is installed at one end of the lens body, and the laser emitter is electrically connected to the signal receiving module.

[0008] Preferably, the lower end of the signal receiving module is connected to a wire, which connects the output end of the signal receiving module to the input end of the wireless transmission module.

[0009] Preferably, an optical lens is sealed and installed at one end of the lens body, and the air outlets of the plurality of air outlet pipes are all located on the surface of the optical lens.

[0010] Preferably, high-pressure air pumps are installed on both sides of the upper part of the mobile frame, a support frame is welded to the lower end of the high-pressure air pump, the support frame is fixedly connected to the mobile frame, an air pump motor is fixedly connected to the rear end of the high-pressure air pump, and a filter screen is provided in the air inlet of the high-pressure air pump.

[0011] Preferably, the air outlet of the high-pressure air pump extends into the sleeve and is sealed to the sleeve, and air guide pipes are installed on both sides of the sleeve. A one-way valve is installed at one end of the air guide pipe. The one-way valve is sealed to the air guide pipe sleeve, and the air guide pipe is sealed to the air outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The dust detection module of this utility model is mounted on a mobile frame, which can be moved by electric wheels. During the movement, the laser emitter emits laser light through the lens body to irradiate dust particles in the air. The particles scatter the light, and the scattered light is received by the signal receiving module and converted into an electrical signal. The signal is then converted into dust concentration through a calibration curve, thereby detecting the dust concentration in the environment. During long-term operation, high-pressure air can be introduced into the airflow ring through a high-pressure air pump. The air outlet pipes distributed in the ring within the airflow ring simultaneously clean the optical lenses inside the lens body. The exhaust air acts on the surface of the optical lenses to remove dust, thus eliminating the need for regular manual wiping of the optical lenses. This makes it suitable for unattended working environments and meets diverse work needs.

[0014] 2. The high-pressure air pump of this utility model is installed on a mobile frame. The air pump motor drives the fan blades to draw air into the sleeve. The one-way valve inside the sleeve introduces the air into the air guide pipe, which then distributes the air to multiple air outlet pipes. At the same time, it thoroughly cleans the lens body, achieving a real-time air curtain protection effect. This avoids light intensity attenuation caused by lens contamination. Furthermore, the start time of the air pump motor can be controlled according to the actual environment to perform powerful cleaning work at regular intervals, resulting in better working effect.

[0024] In addition, the lower end of the signal receiving module 201 is connected to a wire line 202, which connects the output end of the signal receiving module 201 to the input end of the wireless transmission module. The signal receiving module 201 is installed inside the dust detection module 2, and a laser emitter 303 is installed at one end of the lens body 301. The laser emitter 303 is electrically connected to the signal receiving module 201. During movement, the laser emitter 303 emits a laser through the lens body 301 to irradiate the dust particles in the air. The particles scatter, and the scattered light is received by the signal receiving module 201 and converted into an electrical signal. The signal is then converted into a dust concentration through a calibration curve, thereby detecting the dust concentration in the environment.

[0025] It should be noted that an optical lens 302 is sealed and installed at one end of the lens body 301. The air outlets of several air outlet pipes 401 are all located on the surface of the optical lens 302. During long-term operation, high-pressure air can be introduced into the airflow ring 4 by the high-pressure air pump 5. The air outlet pipes 401 distributed in the ring inside the airflow ring 4 clean the optical lens 302 inside the lens body 301 at the same time. The airflow is directed to the surface of the optical lens 302 to remove dust.

[0026] Specifically, the dust detection module 2 is mounted on the mobile frame 1, which can be moved by the electric wheels 101. During the movement, the laser emitter 303 emits a laser through the lens body 301 to irradiate the dust particles in the air. The particles scatter, and the scattered light is received by the signal receiving module 201 and converted into an electrical signal. The signal is then converted into dust concentration through a calibration curve, thereby detecting the dust concentration in the environment. In long-term operation, high-pressure air can be introduced into the airflow ring 4 by the high-pressure air pump 5. The air outlet pipes 401 distributed in the ring inside the airflow ring 4 simultaneously clean the optical lens 302 inside the lens body 301. The exhaust air acts on the surface of the optical lens 302 to remove dust, thus eliminating the need for regular manual wiping of the optical lens 302. This makes it suitable for unattended working environments and meets diverse work needs.

[0027] To address the issue of ineffective airflow cleaning in existing environmental monitoring devices, please refer to [link / reference]. Figure 1 - Figure 4 This embodiment provides the following technical solution:

[0028] In this embodiment, high-pressure air pumps 5 are installed on both sides of the upper part of the mobile frame 1. A support frame 502 is welded to the lower end of the high-pressure air pump 5. The support frame 502 is fixedly connected to the mobile frame 1. An air pump motor 501 is fixedly connected to the rear end of the high-pressure air pump 5. A filter screen 503 is provided in the air inlet of the high-pressure air pump 5. The high-pressure air pump 5 is installed on the mobile frame 1. The air pump motor 501 drives the fan blades to draw air into the sleeve 3. The one-way valve 403 inside the sleeve 3 introduces the air into the air guide pipe 402. The air guide pipe 402 is diverted to multiple air outlet pipes 401. At the same time, the lens body 301 is thoroughly cleaned to achieve the working effect of real-time air curtain protection.

[0029] In fact, the air outlet of the high-pressure air pump 5 extends into the sleeve 3 and is sealed to the sleeve 3. Both sides of the sleeve 3 are equipped with air guide pipes 402. One-way valves 403 are installed at one end of the air guide pipes 402. The one-way valves 403 are sealed to the air guide pipes 402 and the sleeve 3 respectively. The air guide pipes 402 are also sealed to the air outlet pipes 401 to avoid light intensity attenuation caused by lens contamination. In addition, the start time of the air pump motor 501 can be controlled according to the actual environment to perform powerful cleaning work at regular intervals, resulting in better working effect.

[0030] Specifically, the high-pressure air pump 5 is installed on the mobile frame 1. The air pump motor 501 drives the fan blades to draw air into the sleeve 3. The one-way valve 403 inside the sleeve 3 introduces the air into the air guide pipe 402. The air guide pipe 402 distributes the air to multiple air outlet pipes 401, while simultaneously cleaning the lens body 301. This achieves the effect of real-time air curtain protection, avoiding light intensity attenuation caused by lens contamination. Furthermore, the start time of the air pump motor 501 can be controlled according to the actual environment to perform powerful cleaning work at regular intervals, resulting in better working effect.

[0031] Working principle: During use, the mobile frame 1 can be moved by the electric wheels 101. During the movement, the laser emitter 303 emits a laser through the lens body 301 to irradiate dust particles in the air. The particles scatter the light, which is received by the signal receiving module 201 and converted into an electrical signal. The signal is then converted into dust concentration through a calibration curve, thereby detecting the dust concentration in the environment. In long-term operation, high-pressure air can be introduced into the airflow ring 4 through the high-pressure air pump 5. The airflow ring 401, which is distributed in a ring, simultaneously cleans the optical lens 302 inside the lens body 301. The airflow acts on the surface of the optical lens 302. The air pump motor 501 drives the fan blades to draw air into the sleeve 3. The one-way valve 403 inside the sleeve 3 introduces the air into the air guide pipe 402, which then distributes the air to multiple air outlet pipes 401. At the same time, the lens body 301 is thoroughly cleaned, achieving a real-time air curtain protection effect. This prevents light intensity attenuation caused by lens contamination. Furthermore, the start time of the air pump motor 501 can be controlled according to the actual environment to perform powerful cleaning at regular intervals, resulting in better working effects. This eliminates the need for regular manual wiping of the optical lens 302, making it suitable for unattended working environments and meeting diverse work needs.
