Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection gas cabinets, and particularly relates to an environmental protection gas cabinet. Background Art

[0002] For example, in an environmental protection gas cabinet (application number: 202320370931.5) publicly disclosed on the Chinese Patent Network, in order to facilitate the detection of different gases leaking from the inside of the gas cabinet, a plurality of installation pipes are arranged outside the gas cabinet to collect and detect the gases. However, the positions of the installation pipes remain unchanged, and the installation pipes are always connected to the outside world. In this way, gas leakage will occur during the detection and collection of gases. Content of the Utility Model

[0003] Based on the technical problem that gas leakage will occur during the gas detection of the existing gas cabinet, the utility model proposes an environmental protection gas cabinet.

[0004] An environmental protection gas cabinet proposed by the utility model includes a gas cabinet body. A control device is arranged inside the gas cabinet body. The control device includes a control motor, a driving gear, a driven gear, a rotating rod, a driving bevel gear, a driven bevel gear, an adjusting rod and a lifting plate. When the control motor is started, the rotating shaft drives the driving gear to rotate. The driving gear drives the driven gear and the rotating rod to rotate. The rotating rod drives the driving bevel gear to rotate. The driving bevel gear drives the driven bevel gear and the adjusting rod to rotate. The rotation of the adjusting rod makes the lifting plate move up and down.

[0005] Preferably, the control motor is fixedly installed inside the gas cabinet body. The driving gear is fixedly installed on the rotating shaft of the control motor. The rotating rod is rotatably connected inside the gas cabinet body. A rotating circular plate is fixedly installed on the outer surface of the rotating rod. The outer surface of the rotating circular plate is rotatably connected to the inside of the gas cabinet body.

[0006] Through the above technical solution, when the control motor is started, the rotating shaft drives the driving gear to rotate. The rotating circular plate is stuck and rotates inside the gas cabinet body, ensuring that the rotating rod rotates stably.

[0007] Preferably, the driven gear is fixedly installed on the outer surface of the right end of the rotating rod. The outer surface of the driven gear meshes with the outer surface of the driving gear. The driving bevel gear is fixedly installed on the outer surface of the left end of the rotating rod. A lifting cylinder is slidably inserted inside the gas cabinet body.

[0008] Through the above technical solution, when the driving gear rotates, it drives the driven gear to rotate, causing the rotating rod to rotate.

[0009] Preferably, a limiting rod is fixedly installed on the outer surface of the right side of the lifting cylinder. A limiting groove is opened inside the gas cabinet body on the right side of the lifting cylinder. The inside of the limiting groove is slidably connected to the outer surface of the limiting rod. The adjusting rod is threadedly connected inside the lifting cylinder.

[0010] Through the above technical solution, the limiting rod slides in the limiting groove, ensuring that the lifting cylinder can move up and down stably.

[0011] Preferably, a fixed round rod is fixedly installed on the upper surface of the adjusting rod. A limiting round plate is fixedly installed on the upper surface of the fixed round rod. Both the fixed round rod and the limiting round plate are rotatably connected inside the gas cabinet body. The driving bevel gear is fixedly installed on the left end surface of the rotating rod. The driven bevel gear is fixedly installed on the outer surface of the adjusting rod. The outer surface of the driving bevel gear meshes with the outer surface of the driven bevel gear.

[0012] Through the above technical solution, the rotating rod drives the driving bevel gear to rotate, driving the driven bevel gear to rotate, causing the adjusting rod to rotate, and then making the lifting cylinder move up and down. The limiting round plate ensures that the fixed round rod and the adjusting rod rotate stably.

[0013] Preferably, a detection cabinet is fixedly installed on the left side surface of the gas cabinet body. A ventilation pipe is fixedly communicated with the front end of the detection cabinet. The right end of the ventilation pipe is fixedly communicated with the inside of the gas cabinet body. The lifting plate is fixedly installed on the lower surface of the lifting cylinder. An installation pipe is fixedly installed inside the lifting plate. A fixing plate is fixedly installed inside the gas cabinet body on the right side of the installation pipe. A fixing column is fixedly installed on the left side surface of the fixing plate. The outer surface of the fixing column contacts the outer surface of the installation pipe.

[0014] Through the above technical solution, a plurality of gas detectors are installed inside the detection cabinet, which can detect the gas passing into the detection cabinet.

[0015] The beneficial effects in the present utility model are as follows:

[0016] By setting a control device, in order to detect what kind of gas leaks in the gas cabinet, the control motor is started, so that the rotating shaft drives the driving gear to rotate, driving the driven gear to rotate, causing the rotating rod to rotate. The rotating rod drives the driving bevel gear to rotate, driving the driven bevel gear to rotate, making the adjusting rod rotate, and then making the lifting cylinder move up and down, driving the lifting plate to move up and down, causing the fixing column and the installation pipe to deviate, so that the fixing column no longer blocks the installation pipe. Usually, when not detecting, the fixing column blocks the installation pipe orifice to ensure that the gas will not leak. Then the gas in the gas cabinet passes through the installation pipe, and then through the ventilation pipe into the detection cabinet for detection, achieving the effect of preventing gas leakage during gas detection.
