Description

Technical Field

[0001] The utility model relates to the technical field of oxygen content detection in oxygen production workshops, in particular to workshop early warning equipment for detecting oxygen content. Background Art

[0002] There are various dangerous factors in the production of oxygen production workshops, among which asphyxiation poisoning is quite serious. Asphyxiation poisoning is caused by the discharge of large amounts of inert gases such as argon and nitrogen into the room due to misoperation. Asphyxiation poisoning can be caused by inhalation of high concentrations of inert gases. During the maintenance process, if the replacement treatment is not thorough before the equipment maintenance, the oxygen content in the air does not meet the standards, and the operators enter the equipment without using protective equipment, it may cause hypoxia poisoning and suffocation, which can cause suffocation and death of operators in confined spaces. Therefore, it is necessary to install monitoring equipment to measure the oxygen content.

[0003] However, the gas composition measuring equipment currently on the market is usually fixedly installed in the production workshop. When there is a local leakage in the equipment, the oxygen concentration in some areas of the workshop will be too high, causing oxygen poisoning to the workers in the local area.

The fan 4 is electrically connected to the detection and adjustment device 5 and the second gas detector 7, and the output end of the fan 4 is outside the workshop. The guide device 3 includes a supporting square column 301, a motor 302, a first bevel gear 303, a second bevel gear 304, a screw 305 and a movable slider 306. The detection and adjustment device 5 includes a mounting frame 501, a first gas detector 502, a rechargeable battery 503, a plug 504, an electric push rod 505 and a push plate 506.

[0022] There are two supporting square columns 301, which are equidistantly fixed to the edge of the top supporting frame 2 parallel to the crossbeam 8. A cavity is arranged inside the two supporting square columns 301, and equal-length slots are opened on the adjacent end faces. A motor 302 is connected to the top edge of the supporting square column 301 near the top supporting frame 2, and a first bevel gear 303 is connected to the output end of the motor 302. A partition is arranged inside the first supporting square column 301 corresponding to the motor 302, and a screw rod 305 is rotatably connected between the side of the partition away from the motor 302 and the inner wall of the end of the supporting square column 301. A second bevel gear 304 for driving the screw rod 305 is connected to one side of the partition close to the motor 302, and the first bevel gear 303 and the second bevel gear 304 are meshed with each other. After the motor 302 is started, the first bevel gear 303 is driven to rotate, thereby driving the second bevel gear 304 to rotate, thereby realizing power conversion, and the motor 302 is longitudinally arranged, through the conversion of the first bevel gear 303 and the second bevel gear 304, it can be ensured that the axial space of the screw rod 305 is not occupied, thereby ensuring the stroke length of the screw rod 305.

[0023] The outer end of the screw rod 305 is connected with a movable slider 306 which is driven by the screw rod 305 and slides along the notch of the supporting square column 301. The movable slider 306 slides on the bottom surface of the inner wall of the supporting square column 301. The end of the movable slider 306 is used to connect the detection and adjustment device 5. There is a connection relationship between the screw rod 305 and the second bevel gear 304. After the second bevel gear 304 rotates, it will drive the screw rod 305 to rotate, thereby driving the screw rod 305 to rotate, so that the movable slider 306 moves along the notch;

[0024] The two ends of the mounting frame 501 are respectively connected to the end faces of the square grooves of the supporting square column 301 extended out of the moving slider 306. With the drive of the moving slider 306, the two mounting frames 501 move synchronously and drive the first gas detector 502 to move in one direction. When the mounting frame 501 moves to the other end of the groove, the motor 302 rotates in the opposite direction to drive the mounting frame 501 to move in the opposite direction. A plurality of first gas detectors 502 are equidistantly connected to the bottom surface of the mounting frame 501. The first gas detector 502 is located at the top of the workshop and is mainly used to detect nitrogen leaks in the workshop and oxygen sprayed upward due to leakage. The bottom edge of the mounting frame 501 is connected to a longitudinal extension bracket 6, and the longitudinal extension bracket 6 slides in the surface groove of the crossbeam 8 when driven by the mounting frame 501. The two longitudinal extension brackets 6 are close to each other at the ends. A second gas detector 7 is provided on the surface, and the second gas detector 7 is mainly used to detect oxygen leakage and nitrogen sprayed downward. Since the density of nitrogen is relatively light during slow leakage and is usually distributed in the upper area of ​​the workshop, the first gas detector 502 can make a judgment on the nitrogen leakage in time, and cooperate with the second gas detector 7 to detect nitrogen leakage in any direction. Similarly, oxygen density is relatively large and usually sinks, and will be detected by the second gas detector 7 first. By moving the mounting frame 501 back and forth, in cooperation with the first gas detector 502 and the second gas detector 7 on the top, the oxygen content in the workshop can be detected. When the oxygen or nitrogen concentration exceeds the threshold, the fan 4 is started to exhaust to the outside, and an alarm is sounded through the first gas detector 502 and the second gas detector 7;

[0025] The number of rechargeable batteries 503 provided corresponds to the first gas detector 502, and they are equidistantly embedded and installed on the top surface of the mounting frame 501. The top surface of the mounting frame 501 is slidably connected with a plug 504. The plug 504 is electrically connected to the rechargeable battery 503. When the mounting frame 501 moves back and forth, it will drive the first gas detector 502 and the second gas detector 7 to move. In order to avoid the problem of difficult installation of the lines caused by the movement, the rechargeable battery 503 is specially used to power the first gas detector 502 and the second gas detector 7. Electric push rods 505 are fixedly installed on the top surface of the mounting frame 501 on both sides of the plug 504. The output end of the electric push rod 505 is connected to Push plate 506, push plate 506 is fixedly installed on the back of plug 504, and the top support frame 2 close to motor 302 is provided with the same number of sockets corresponding to plug 504, and when electric push rod 505 is retracted, plug 504 is driven to connect with the socket. After the staff gets off work, the motor 302 is controlled to drive the mounting frame 501 close to motor 302 and be at the end of the slot, and at the same time, the electric push rod 505 is started to retract, and the plug 504 is inserted into the socket to charge the rechargeable battery and turn off the motor. When the staff goes to work, the electric push rod 505 is controlled to be pushed out to cut off the power, and the motor 302 is turned on to drive the mounting frame 501 to perform periodic reciprocating motion.
