Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically to an online monitoring type toxic and harmful gas detection alarm. Background Technology

[0002] An alarm is an electronic product that uses sound, light, air pressure, or other means to remind or warn us to take certain actions in order to prevent or mitigate the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. With the advancement of technology, mechanical alarms are increasingly being replaced by advanced electronic alarms, which are frequently used in chemical plant tank areas, pipeline transportation systems (such as long-distance oil and gas pipelines and chemical material transportation pipelines).

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: most existing toxic and harmful gas detection alarms are fixed in one place, and the gas detection port can only detect gases in the surrounding area. For example, in storage tanks, there are leakage risks in different areas such as the top of the tank, near the tank wall, and around the manhole. It is impossible to detect leaks in a timely and efficient manner, which urgently needs to be improved. Therefore, we propose an online monitoring type toxic and harmful gas detection alarm. Utility Model Content

[0004] The purpose of this invention is to provide an online monitoring type toxic and harmful gas detector and alarm, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring type toxic and harmful gas detector alarm, comprising an alarm housing, a support mechanism, a gas supply mechanism, and a limiting mechanism;

[0006] A gas detection port is integrally formed on one side of the alarm housing, and an alarm is fixedly installed on the top of the alarm housing;

[0007] The support mechanism includes a crank arm, which is fixed to the alarm housing and is located directly outside the gas detection port.

[0008] The air delivery mechanism includes hoses, and there are three sets of hoses in total;

[0009] The limiting mechanism includes screw blocks, and there are two sets of screw blocks.

[0010] As an optional solution to the technical solution of this application, one end of each of the three sets of hoses is connected to the air collecting plate, and an air cavity is opened in the air collecting plate. A limit frame is fixedly installed on the outer side of the end of the hose away from the air collecting plate.

[0011] As an optional solution to the technical solution of this application, an air pump is fixedly inserted inside the crank arm, the air pump's pipe is connected to the air collection plate, and a power-carrying wire is electrically connected to one side of the air pump.

[0012] As an optional solution to the technical solution of this application, reinforcing rods are placed on both sides of the air pump, and the two ends of the reinforcing rods are fixedly connected to the crank arm and the air collection plate, respectively.

[0013] As an optional solution to the technical solution of this application, the screw block is fixed to the top of the limiting frame, a movable plate is placed on the outside of the screw block, and a strong magnet is fixedly installed on the upper surface of the movable plate.

[0014] As an optional solution to the technical solution of this application, anti-slip pads are fixedly installed on both sides of the movable plate, a screw is screwed into the middle of the screw block through a screw hole, the outer end of the screw is rotatably connected to the movable plate on the same side through a bearing, and a rotating block is fixedly installed at the end of the screw.

[0015] As an optional solution to the technical solution of this application, a hanging ring is fixedly installed on the upper surface of the limiting frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model discloses an online monitoring type toxic and harmful gas detector and alarm. By setting up an air pump, a crank arm, and hoses, during the use of the gas detector and alarm, one end of the hose can be held and placed on the side of a gas tank or pipeline with a risk of leakage. In the same way, three sets of hoses are placed and fixed on the side of the tank or pipeline. During this process, the micro air pump can slowly draw air, and with the help of the gas collection plate, gas can be drawn from different locations in the tank through the three sets of hoses and delivered to the gas detection port for detection, quickly determining whether there is a leak. Compared with the traditional "single-point sampling", it is more efficient and can avoid safety accidents caused by missing leak points due to local sampling. It can also indirectly reduce the amount of gas wasted.

[0018] 2. This utility model discloses an online monitoring type toxic and harmful gas detector and alarm. It is equipped with movable plates and hanging rings. By rotating a screw, the movable plates can move towards each other, clamping them onto an object. By rotating the screw in the opposite direction, the movable plates can move outwards, bringing them into contact with two objects. They can also be attracted to an iron block by a strong magnet for positioning. The hanging rings can be used to hook onto external objects for hanging and placement. The appropriate limiting method can be selected based on the fixing conditions around the tank, pipeline, or other object, making it widely applicable. Attached Figure Description

[0026] First, after placing the alarm in the designated area, multiple gas delivery pipes can be placed in the detection area of ​​the tank or gas pipe. During this period, multi-point gas extraction detection can be carried out, making the detection more timely and efficient.

[0027] Specifically, one end of each of the three sets of hoses 3 is connected to the air collection plate 32, and an air chamber is opened in the air collection plate 32. A limit frame 31 is fixedly installed on the outer side of the end of the hose 3 away from the air collection plate 32. An air pump 21 is fixedly inserted through the crank arm 2.

[0028] During the use of the gas detection alarm, one end of the hose 3 can be held and placed on the side of a gas tank or pipeline with a risk of leakage. In the same way, the three sets of hoses 3 are placed and fixed on the side of the tank or pipeline. During this process, the micro air pump 21 can slowly draw air, and with the help of the gas collection plate 32, the gas can be drawn from different locations in the tank through the three sets of hoses 3 and sent to the gas detection port 12 for detection, so as to quickly determine whether there is a leak. Compared with the traditional "single-point sampling", it is more efficient and can avoid safety accidents caused by missing the leak point due to local sampling. It can also indirectly reduce the amount of gas wasted.

The movable plates 4 can be moved outward by rotating the screw 45 in the opposite direction, allowing them to abut against two objects. The movable plates 4 can be attracted to an iron block by a strong magnet 42, allowing them to be positioned. They can also be hooked onto an external object by the hanging ring 44, enabling hanging and placement. The appropriate limiting method can be selected according to the fixing conditions around the tank or pipeline, making it widely applicable.
