Description

Technical Field

[0001] The utility model relates to the field of safety alarm protection equipment, in particular to a combustible gas detection alarm device. Background Art

[0002] At present, all kinds of detection alarms are usually fixed, and fixed detection alarms are all fixedly installed. When detecting toxic and harmful gases lighter than air, fixed detection alarms are usually required to be installed 1-2 meters above the release source. Therefore, when facing confined spaces such as booster rooms, they are installed at the highest point above the release source in the confined space, at a high position, or when there are reaction treatment towers, tower kettles and other containers of a certain height, they need to be higher than the height of the towers and tower kettles.

[0003] However, when conducting regular calibration of detection alarms, it is very difficult to calibrate detection alarms that are installed at very high positions. This not only increases the difficulty of calibrating the detection alarms, but also makes it difficult to ensure the personal safety of construction workers.

[0004] Therefore, it is desired in the art to provide a combustible gas detection alarm device to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a combustible gas detection alarm device, which can prompt the suspended signal cable in the storage cavity to be released or recovered through the forward or reverse rotation of the motor, so as to further achieve the purpose of adjusting the height of the detector, thereby facilitating subsequent maintenance work.

[0006] According to the utility model, a combustible gas detection alarm device is provided, comprising a detector for monitoring combustible gas,

[0007] A lifting mechanism is arranged above the detector and is used to be fixed on the platform, the lifting mechanism includes a lifting body, a storage cavity arranged in the lifting body, and a hanging signal cable wound in the storage cavity and connected to the detector, and

[0008] A magnetic charger is arranged between the lifting mechanism and the detector.

[0009] In one embodiment, the magnetic charger includes a first magnetic seat fixed to the lower end surface of the lifting body.

[0010] In one embodiment, the magnetic charger further includes a second magnetic seat adapted to the first magnetic seat, and a battery arranged between the second magnetic seat and the detector.

[0011] In one embodiment, the first magnetic base is the positive pole of the magnetic wireless charger; the second magnetic base is the negative pole of the magnetic wireless charger.

[0012] In one embodiment, the lifting mechanism further includes a motor connected to the lifting body and used to drive the suspended signal cable.

[0013] In one embodiment, the length of the hanging signal cable is in the range of 5 to 20 m.

[0014] In one embodiment, the combustible gas detection alarm device further includes a power signal cable disposed on the first magnetic seat and used to connect to the gas alarm controller.

[0015] The motor is configured to retract the suspended signal cable during forward rotation to allow the second magnetic seat to move upward; and the motor is configured to release the suspended signal cable during reverse rotation to allow the second magnetic seat to move downward.

[0016] In one embodiment, the detector further comprises a digital display, a circuit board disposed within the digital display, and a sensor disposed below the digital display and used to monitor combustible gas, wherein the sensor is connected to the circuit board.

[0017] In one embodiment, the detector further comprises an alarm arranged above the sensor and on one side of the digital display, wherein the alarm is connected to the circuit board.

[0018] In one embodiment, the alarm is an audible and visual alarm.

[0021] Secondly, the utility model can control the forward or reverse rotation of the motor through a remote control, thereby prompting the hanging signal cable in the storage cavity to be released or recovered, so as to further achieve the purpose of adjusting the height of the detector, thereby facilitating subsequent maintenance work.

[0022] Preferably, when the motor is controlled by the remote control to rotate forward, the hanging signal cable can be recovered, thereby driving the second magnetic seat to move up until it abuts against the first magnetic seat. At this time, the detector reaches the maximum height to more easily meet the requirements of inspection and installation. In this process, the first magnetic seat and the second magnetic seat are in contact with each other and can perform adsorption and charging work.

[0023] Preferably, the hanging signal cable can be released when the motor is reversed by the remote control. Therefore, the second magnetic seat is separated from the first magnetic seat under the action of gravity, and the hanging signal cable is slowly relaxed until the hanging signal cable in the storage cavity reaches the maximum extension amount, and the detector reaches the minimum height, so that the construction personnel can perform maintenance work more easily.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than an exhaustive list of all embodiments. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0029] The utility model will be further described below in conjunction with the accompanying drawings.

[0030] Figure 1 The structure of the combustible gas detection alarm device 100 according to the present invention is schematically shown.

[0031] like Figure 1 As shown, according to the combustible gas detection alarm device 100 of the present invention, it includes a detector for monitoring combustible gas, a lifting mechanism arranged above the detector, and a magnetic charger arranged between the lifting mechanism and the detector. Preferably, the lifting mechanism can be fixed on a platform (not shown), so that the requirements of detection and installation can be more easily met.

[0032] In one embodiment, Figure 1As shown, the lifting mechanism includes a lifting body 21, a storage cavity 22 disposed in the lifting body 21, and a hanging signal cable 23 wound in the storage cavity 22 and connected to the detector. Preferably, the height of the detector can be changed by retrieving or releasing the hanging signal cable 23.

[0033] Preferably, when maintenance is required, the detector can be lowered by simply releasing the hanging signal cable 23, so that maintenance personnel can more easily access the detector. This not only reduces the difficulty of maintenance to improve the efficiency of detection and maintenance by construction personnel, but also ensures the personal safety of construction personnel.

[0034] Preferably, when work is required (detection of combustible gas), the detector can be raised and fixed in a standard installation position by only retrieving the hanging signal cable 23, thereby facilitating subsequent monitoring work.

[0035] In one embodiment, Figure 1 As shown, the magnetic charger includes a first magnetic seat 31. Preferably, the first magnetic seat 31 is fixed at the lower end surface of the lifting body 21, so that it can more easily perform adsorption charging with the second magnetic seat 32 (described below).

[0036] Preferably, the first magnetic seat 31 is configured as a positive pole of a magnetic wireless charger. Figure 1 As shown, the combustible gas detection alarm device 100 also includes a power signal cable 40 disposed on the first magnetic seat 31. Preferably, the first magnetic seat 31 can always be connected to the power signal line (not shown) of the gas alarm controller through the power signal cable 40, thereby facilitating the subsequent adsorption charging and signal transmission work of the first magnetic seat 31 and the second magnetic seat 32.

[0037] In one embodiment, Figure 1 As shown, the magnetic charger also includes a second magnetic seat 32 adapted to the first magnetic seat 31, and a battery 33 disposed between the second magnetic seat 31 and the detector. Preferably, the battery 33 can provide sufficient power for the detector so that it can detect combustible gas for a long time.

[0038] Preferably, the second magnetic seat 32 is configured as a negative pole of a magnetic wireless charger. Accordingly, when the power signal cable 40 is connected to the power signal line of the gas alarm controller, the first magnetic seat 31 and the second magnetic seat 32 are in contact with each other and can perform adsorption charging.

[0039] In one embodiment, Figure 1As shown, the lifting mechanism also includes a motor 24 connected to the lifting body 21 and used to drive the hanging signal cable 23. Preferably, the motor 24 can rotate forward or reverse, thereby prompting the hanging signal cable 23 in the storage cavity 22 to achieve the effect of releasing or recovering, so as to further achieve the purpose of adjusting the height of the detector, thereby facilitating subsequent maintenance work.

[0040] In the present invention, the forward and reverse rotations of the motor 24 can be controlled by a remote controller (not shown).

[0041] Preferably, when the remote control controls the motor 24 to rotate forward, the hanging signal cable 23 can be recovered, thereby driving the second magnetic seat 32 to move upward until it abuts against the first magnetic seat 31. At this time, the detector reaches the maximum height to more easily meet the requirements of inspection and installation. In this process, the first magnetic seat 31 and the second magnetic seat 32 are in contact with each other and can perform adsorption and charging work.

[0042] Preferably, the hanging signal cable 23 can be released when the motor 24 is reversed by the remote control. Therefore, the second magnetic seat 32 is separated from the first magnetic seat 31 under the action of gravity, and the hanging signal cable 23 is slowly relaxed until the hanging signal cable 23 in the storage cavity 22 reaches the maximum extension amount, and the detector reaches the minimum height at this time, so that the construction personnel can perform maintenance work more easily.

[0045] In one embodiment, Figure 1 As shown, the combustible gas detection alarm device 100 further includes an alarm 14 disposed above the sensor 13. Preferably, the alarm 14 is located on one side of the digital display 11, and the alarm 14 is connected to the circuit board 12.

[0046] In the utility model, the sensor 13 can monitor the concentration of combustible gas in real time and transmit the monitoring data to the circuit board 12 in real time; the alarm 14 can receive the monitoring data from the circuit board 12 in real time, and transmit the monitored data to the gas alarm controller through the signal cable for judgment based on the monitored data, thereby choosing whether to issue an alarm signal.

[0047] In one embodiment, the alarm 14 is preferably an audible and visual alarm. Preferably, the audible and visual alarm is provided to meet the special requirements of customers for alarm loudness and installation location, and can simultaneously emit both audible and visual alarm signals, and the product is applicable to a wide range of fields.

[0051] Preferably, when the remote control controls the motor 24 to rotate forward, the hanging signal cable 23 can be recovered, thereby driving the second magnetic seat 32 to move upward until it abuts against the first magnetic seat 31. At this time, the detector reaches the maximum height to more easily meet the requirements of inspection and installation. In this process, the first magnetic seat 31 and the second magnetic seat 32 are in contact with each other and can perform adsorption and charging work.
