Description

Technical Field

[0001] This utility model relates to the field of environmental protection testing technology, specifically a gas detection device for environmental protection acceptance. Background Technology

[0002] With the continuous development of my country's manufacturing industry, the number of enterprises is also increasing. For enterprises that need to emit flue gas, environmental compliance acceptance of their production equipment is particularly important; only by obtaining the corresponding qualifications can they carry out the corresponding production operations.

[0003] In practice, when inspectors go out to conduct acceptance tests on gas emission equipment of multiple companies, the equipment used for testing is inconvenient to carry. When testing pipelines at high altitudes, the detection end is difficult to adjust in terms of height and angle, making it impossible to get close to the pipeline equipment to be tested, resulting in poor detection accuracy. Therefore, we propose a gas detection device for environmental protection acceptance. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a gas detection device for environmental protection acceptance. This device features a detection and adjustment unit that improves the stability of the device's placement and allows adjustment of the air inlet's orientation and height to bring it closer to the pipes and other components being tested, thus ensuring accurate detection results. A carrying handle allows for easy lifting, and the bottom support and frame can be folded up, facilitating the carrying of the device to different locations for testing by inspection personnel. This effectively solves the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas detection device for environmental protection acceptance, comprising a mounting box, an air detection unit, and a detection adjustment unit;

[0006] Installation box: horizontally arranged, with a base underneath;

[0007] Air detection unit: installed inside the mounting box;

[0008] The detection and adjustment unit includes a hydraulic cylinder, an external rotor motor, extension rods, support feet, and fixed angles. A hydraulic cylinder is fixedly mounted on the upper center of the fixed angles, and the hydraulic cylinder is vertically arranged. The external rotor motor is mounted on the bottom of the mounting box. Four fixed angles with bolt through holes are fixedly connected to the four sides of the external rotor motor in a circumferential array. The fixed angles are fixedly connected to the bottom of the mounting box by bolts. The central shaft of the external rotor motor is fixedly connected to the central axis of the upper telescopic end of the hydraulic cylinder. An extension rod is slidably connected to each of the four corners of the base. The four extension rods are distributed in an X-shape, and a support foot is fixedly mounted on the lower side of the end of each extension rod.

[0009] The mounting box is used to install the air detection unit, which performs the function of detecting ambient gases. The base provides the main support for the device. The extension rods at the four corners of the base can be pulled outwards, and together with the end feet, they can provide auxiliary support for the device. By expanding the support range, the stability of the device can be further ensured. The hydraulic cylinder can drive the mounting box to lift and lower, and the external rotor motor can drive the mounting box to rotate, thereby adjusting the orientation and height of the air inlet to bring it closer to the pipes and other devices to be tested.

[0010] Furthermore, the detection and adjustment unit also includes a carrying handle and a fixing block.

An air intake pump is embedded on the left side of the mounting box, and both the intake end of the air intake pump and the one-way valve are connected to the air collection chamber. The air intake pump creates negative pressure inside the air collection chamber, allowing ambient air to enter the chamber through the one-way valve. The one-way valve prevents backflow of air entering the air collection chamber.

[0012] Furthermore, the air detection unit also includes a detector and an exhaust valve. The detector is embedded in the front of the mounting box, with its display screen facing forward. The detector's detection end extends into the air collection chamber. An exhaust valve is installed on the right side of the mounting box, and the exhaust valve is connected to the exhaust end of the intake pump. The detector is used to detect the collected air and can display the detection results on the front display screen. After the detection is completed, the intake pump discharges the gas outward through the exhaust valve.

[0013] Furthermore, the air detection unit also includes a pull-out baffle and a limiting strip. The pull-out baffle is slidably connected to the left side of the mounting box, and the upper end of the pull-out baffle is fixedly connected to the limiting strip. The pull-out baffle can be pulled upwards. When using the device, the pull-out baffle can be pulled upwards by lifting the limiting strip, thereby keeping the air inlet unobstructed. After use, the pull-out baffle can be inserted to close the air inlet.

[0014] Furthermore, the detection and adjustment unit also includes fitting grooves. A fitting groove is provided on the lower side of each of the four corners of the base. The fitting groove has a quarter-circle structure, and its radius is the same as the radius of the support leg. After use, the four extension rods can be folded inwards for easier carrying. When the extension rods are folded, the circular support legs can be stored in the fitting grooves.

The air intake pump 35 creates a negative pressure inside the air collection chamber 32, allowing ambient air to enter the air collection chamber 32 through the one-way valve 33. The one-way valve 33 prevents the backflow of air entering the air collection chamber 32.

[0031] The air detection unit 3 also includes a detector 34 and an exhaust valve 36. The detector 34 is embedded in the front of the mounting box 1, with its display screen facing forward.
