Description

Technical Field

[0001] This utility model relates to the field of environmental protection monitoring equipment technology, specifically a protective device for stationary pollution source monitoring equipment. Background Technology

[0002] Stationary pollution source monitoring equipment consists of specialized instruments installed at or near the emission outlets of stationary pollution sources to monitor the emission status of these sources in real time. Examples of stationary pollution sources include factory chimneys and wastewater treatment plant discharge outlets, and monitoring equipment is installed at these locations.

[0003] Its functions are significant: First, it provides precise monitoring, enabling real-time and accurate measurement of pollutant concentrations such as sulfur dioxide and nitrogen oxides in exhaust gases, as well as indicators such as chemical oxygen demand and ammonia nitrogen in wastewater, providing scientific data for environmental protection departments. Second, it assists in supervision, allowing environmental protection departments to determine whether enterprises meet emission standards based on monitoring data, promptly penalize violating enterprises, and urge rectification. Third, it promotes emission reduction, enabling enterprises to understand their own emission situation through monitoring data, take targeted emission reduction measures, optimize production processes, achieve energy conservation and emission reduction goals, and contribute to the improvement of the ecological environment.

[0004] However, in actual use, traditional monitoring equipment faces many challenges. On the one hand, high-temperature environments may cause the performance of internal electronic components to decline or even be damaged. On the other hand, external dust particles may enter the equipment, affecting the normal operation of internal electronic components and sensors. Although there are some protective measures for monitoring equipment on the market, most of them have poor protective effects. For example, some protective devices only use simple shells for shielding, which cannot effectively remove the dust accumulated inside. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for stationary pollution source monitoring equipment, so as to solve the many challenges faced by traditional monitoring equipment in actual operation as mentioned in the background art. On the one hand, high temperature environment may cause the performance of internal electronic components to decline or even be damaged; on the other hand, external dust particles may enter the equipment, affecting the normal operation of internal electronic components and sensors. Although there are some protective measures for monitoring equipment on the market, most of them have the problem of poor protection effect. For example, some protective devices only use a simple shell for shielding, which cannot effectively remove the dust accumulated inside.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a protective cover, and the fixed pollution source monitoring equipment is fixedly installed inside the protective cover;

[0007] The bottom of the protective cover is fixedly connected to a dust discharge trough. A control motor is fixedly installed on the outer side of the lower end of the dust discharge trough. A swing shaft is fixedly installed on the inner drive shaft of the control motor. A sealing cover for blocking and sealing the lower opening of the dust discharge trough is fixedly installed on the outer curved surface of the swing shaft. A compressed air cylinder is fixedly installed on the rear end of the protective cover. An air blowing pipe is rotatably connected to the inner side of the upper end of the protective cover through a rotating shaft. An air blowing nozzle is fixedly connected to the bottom of the air blowing pipe. A connecting pipe is rotatably connected to the outer end of the air blowing pipe through a rotating shaft. A limiting slide groove is fixedly installed on the inner side of the upper end of the protective cover. A transmission rack is movably connected to the inner wall of the limiting slide groove. A transmission gear is meshed with the upper end of the transmission rack. An electric telescopic rod is fixedly installed through the rear side of the upper end of the protective cover.

[0008] Preferably, an arc-shaped cover is fixedly installed on the top of the protective cover, and a sealing door is hinged to the front end of the protective cover, with a sealing ring adhered to the inner side of the sealing door.

[0009] Preferably, the protective cover has heat dissipation slots on both sides, and there are two heat dissipation slots, which are symmetrically distributed on both sides of the protective cover. An exhaust fan is fixedly installed on the inner side of the heat dissipation slot, and a filter screen is detachably fixedly installed on the outer end of the heat dissipation slot.

[0010] Preferably, the lower end of the dust discharge trough is conical, and the swing shaft is rotatably connected to the lower end of the dust discharge trough by a bearing seat.

[0011] Preferably, there are several air tubes, which are symmetrically distributed along the inner side of the upper end of the protective cover, and there are several air nozzles, which are symmetrically distributed along the bottom of the air tubes.

[0013] Preferably, the transmission gear is fixedly installed on the outer curved surface of the side end of the air blowing pipe, and the telescopic part of the front end of the electric telescopic rod is fixedly installed on the rear end of the transmission rack.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the inside of the protective cover needs to be cleaned, the present invention controls the start of a control motor. When the control motor is started, it drives the swing shaft to rotate. When the swing shaft rotates, it drives the sealing cover to swing open the lower opening of the dust discharge groove. When the lower opening of the dust discharge groove is open, the compressed gas cylinder is opened. When the compressed gas cylinder is opened, the compressed gas is discharged into the connecting pipe and then into the blowing pipe. When the compressed gas enters the blowing pipe, it is blown downward through the blowing nozzle. When the compressed gas blows downward, it blows the dust and impurities accumulated inside the protective cover out through the dust discharge groove.

[0016] This invention also features a transmission rack that moves linearly back and forth along the inner wall of the limiting groove when the electric telescopic rod extends or retracts. As the transmission rack moves linearly back and forth, it meshes with and drives the transmission gear to rotate back and forth. When the transmission gear rotates back and forth, it drives the air blowing pipe to rotate back and forth. When the air blowing pipe rotates back and forth, it drives the air blowing nozzle to swing back and forth and blow air. Thus, while protecting the fixed pollution source monitoring equipment through the protective cover, it also facilitates the swinging air jet dust removal inside the protective cover, further improving the cleaning effect inside the protective cover.

[0023] The protective cover 1 has two heat dissipation slots 4 on both sides, symmetrically distributed on both sides of the protective cover 1. A ventilation fan 5 is fixedly installed inside the heat dissipation slot 4, and a filter screen 6 is detachably fixedly installed at the outer end of the heat dissipation slot 4. A dust exhaust trough 7 is fixedly connected to the bottom of the protective cover 1, and the lower end of the dust exhaust trough 7 is conical.

A swing shaft 9 is fixedly installed on the inner drive shaft of the control motor 8, and the swing shaft 9 is rotatably connected to the lower end of the dust exhaust trough 7 via a bearing seat. A sealing cover 10 is fixedly installed on the outer curved surface of the swing shaft 9 to cover and seal the lower opening of the dust exhaust trough 7. A compressed air cylinder 11 is fixedly installed at the rear end of the protective cover 1. An air blowing pipe 12 is rotatably connected through a rotating shaft on the inner side of the upper end of the protective cover 1, and there are several air blowing pipes 12, each designed to protect the protective cover. The upper inner side of the cover 1 is symmetrically distributed with air blowing pipes 12 and air blowing nozzles 13 fixedly connected to the bottom. There are several air blowing nozzles 13, which are symmetrically distributed with respect to the bottom of the air blowing pipes 12. The outer end of the air blowing pipes 12 is connected to a connecting pipe 14 through a rotating shaft. The connecting pipe 14 is fixedly installed on the outer side of the upper end of the cover 1. The rear end of the connecting pipe 14 is connected to the compressed air cylinder 11 through an electromagnetic control valve and an air pipe. The upper inner side of the cover 1 is fixedly installed with a limiting groove 15. The inner wall of the limiting groove 15 is movably connected to a transmission rack 16. The upper end of the transmission rack 16 is meshed with a transmission gear 17. The transmission gear 17 is fixedly installed on the outer curved surface of the side end of the air blowing pipe 12. The rear side of the upper end of the cover 1 is fixedly installed with an electric telescopic rod 18. The telescopic part of the front end of the electric telescopic rod 18 is fixedly installed on the rear end of the transmission rack 16.

[0024] Working principle: In use, this utility model uses a protective cover 1 to shield and protect the fixed pollution source monitoring equipment. When the protective cover 1 shields and protects the fixed pollution source monitoring equipment, the ventilation fan 5 is turned on by control. When the ventilation fan 5 is turned on, it will circulate and exhaust air inside the protective cover 1, so as to dissipate heat and cool down the fixed pollution source monitoring equipment. The filter screen 6 blocks and filters the heat dissipation slot 4 to prevent external pollutants and impurities from entering the interior of the protective cover 1.

[0025] When the inside of the protective cover 1 needs to be cleaned, the control motor 8 is turned on by controlling it. When the control motor 8 is turned on, it will drive the swing shaft 9 to rotate. When the swing shaft 9 rotates, it will drive the sealing cover 10 to swing open the lower opening of the dust discharge groove 7. When the lower opening of the dust discharge groove 7 is open, the compressed gas cylinder 11 is turned on by controlling it. When the compressed gas cylinder 11 is turned on, the compressed gas will be discharged into the connecting pipe 14 and enter the blowing pipe 12 through the connecting pipe 14. When the compressed gas enters the blowing pipe 12, it will be blown downward through the blowing nozzle 13. When the compressed gas is blown downward, it will blow the dust and impurities accumulated inside the protective cover 1 out through the dust discharge groove 7.

[0026] Simultaneously, the electric telescopic rod 18 is extended and retracted by control. When the electric telescopic rod 18 extends and retracts, it drives the transmission rack 16 to move linearly back and forth along the inner wall of the limiting slide groove 15. When the transmission rack 16 moves linearly back and forth, it meshes and drives the transmission gear 17 to rotate back and forth. When the transmission gear 17 rotates back and forth, it drives the air blowing pipe 12 to rotate back and forth. When the air blowing pipe 12 rotates back and forth, it drives the air blowing nozzle 13 to swing back and forth and blow air. Thus, the protective cover 1 protects the fixed pollution source monitoring equipment while facilitating the swinging air jet dust removal inside the protective cover 1, thereby further improving the cleaning effect inside the protective cover 1.
