Description

Technical Field

[0001] The utility model belongs to the technical field of combustible gas detection, in particular to an online combustible gas detection device for dangerous workplaces. Background Art

[0002] As the application field of combustible gas gradually expands, while bringing convenience to people's lives, due to the flammable and explosive characteristics of combustible gas, when its concentration reaches a certain range, it is very easy to cause an explosion accident, posing a great threat to people's life and property safety. Therefore, when working in dangerous workplaces, it is necessary to detect combustible gas.

[0003] Existing combustible gas detection devices are usually fixed with screws, etc., which are not easy to operate during installation and removal, and require drilling holes in the wall and other places for installation. Since the working position is not fixed when working in hazardous workplaces, this installation method is not easy to move the detection device at any time. Therefore, we proposed an online combustible gas detection device for hazardous workplaces. Utility Model Content

[0004] The purpose of the utility model is to provide an online combustible gas detection device for hazardous workplaces. By setting up a clamping assembly, the detector can be quickly installed and disassembled, making it convenient to move the device to other locations for use. This solves the problem that existing combustible gas detection devices are usually fixed with screws, etc., which makes them difficult to operate during installation and disassembly, and it is not easy to move the detection device at any time.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an online detection device for combustible gas in dangerous workplaces, comprising a fixed seat, a detector is fixedly connected to the front of the fixed seat, a fixed clamp block is fixedly connected to the right side of the fixed seat, a clamping assembly is arranged on the left side of the fixed seat, and a turning handle is arranged above the fixed seat;

[0007] The clamping assembly includes a movable clamping block, a connecting frame is fixedly connected to the left side of the movable clamping block, a movable block is slidably connected inside the fixed seat, and a threaded rod is arranged inside the movable block. By setting up the clamping assembly, the detector can be quickly installed and disassembled, and the device is convenient to be moved to other locations for use.

[0008] Furthermore, the fixed clamp block and the movable clamp block are fixedly connected to each other on one side thereof where they are close to each other, an alarm light is arranged on the right side of the detector, and a limit block is fixedly connected to the inner wall of the fixed seat. By arranging the alarm light, a light alarm can be generated after detecting that the concentration of combustible gas exceeds the standard, so as to facilitate timely observation by the staff.

[0009] Furthermore, a bevel gear is fixedly connected to the outer surface of the threaded rod, a threaded ring is fixedly connected to the inner wall of the movable block, a support frame is rotatably connected to the left side of the threaded rod, and the front and back sides of the support frame are respectively fixedly connected to the front and back sides of the inner wall of the fixing seat. The support frame is provided to support the threaded rod, thereby improving the stability of the threaded rod during rotation.

[0010] Furthermore, a telescopic rod is fixedly connected to the right side of the connecting frame, a slot is opened inside the telescopic rod, a plug rod is inserted into the slot, and a pull block is fixedly connected to the top of the plug rod. By setting the telescopic rod, the distance of the movable clamping block can be adjusted, so that more cylindrical structures or square structures of different sizes can be clamped, reducing limitations.

[0011] Furthermore, a rotating rod is fixedly connected to the bottom of the rotating handle, and the rotating rod is rotatably connected to the fixed seat. A bevel gear 2 is fixedly connected to the bottom of the rotating rod, and the bevel gear 1 is meshingly connected with the bevel gear 2. When the rotating handle drives the rotating rod to rotate, the bevel gear 2 follows the rotation, and the bevel gear 2 drives the threaded rod to rotate through the bevel gear 1.

[0012] Furthermore, the telescopic rod is slidably connected to the movable block, the insertion rod is plugged into the movable block, the right side of the movable block is in contact with the left side of the limit block, and steel columns of different sizes can be clamped and fixed through the movement of the movable block. The insertion rod is used to connect the telescopic rod and the movable rod.

[0013] Furthermore, the right side of the threaded rod is rotatably connected to the right side of the inner wall of the fixed seat, the threaded rod is threadedly connected to the threaded ring, and the support frame is slidably connected to the movable block. Since the support frame is slidably connected to the movable block, it will not affect the movement of the movable block and can limit the movable block.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model sets a clamping assembly, specifically, the threaded rod is rotated by rotating the handle, and the movable block drives the movable clamping block to move. The movable clamping block and the fixed clamping block cooperate to clamp the steel column at the construction site, so as to fix the detector. The movable block can be moved in the opposite direction by rotating the handle in the opposite direction, so as to release the fixation. The device can be quickly disassembled and can be moved to other locations for use.

[0016] 2. The utility model sets a telescopic rod, specifically, pulls the pull block to drive the insertion rod to move and pull it out, pulls the connecting frame to drive the telescopic rod to move, and can adjust the distance of the movable clamping block. After the adjustment is completed, the insertion rod is inserted into the movable block, and the connecting frame is fine-tuned to make the insertion rod inserted into the telescopic rod. By adjusting the distance, more cylindrical structures or square structures of different sizes can be clamped to reduce limitations.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
