Description

Technical Field

[0001] This utility model relates to the field of detector sensitivity detection technology, and in particular to a detector sensitivity detection device that facilitates the replacement of gas cylinders. Background Technology

[0002] Gas / fire detectors are integrated instruments capable of detecting both flammable gas leaks and fires. These instruments are suitable for hazardous locations containing flammable or toxic gases, and can continuously monitor the concentration of the gas in the air up to its lower explosive limit. They are widely used in various industries such as gas, petrochemicals, metallurgy, steel, coking, and power generation, making them ideal monitoring instruments for ensuring property and personal safety. To determine whether there are gas leaks in the storage space containing toxic or toxic gases, and to assess the sensitivity and usability of fire detectors in various buildings, ensuring the safety of personnel and property in these spaces, timely and effective leak detection, and enabling personnel to effectively handle crisis events, it is necessary to test the sensitivity of the gas / fire detectors in these locations.

[0003] Currently, the sensitivity testing of gas / fire detectors involves pointing a detection device at the detector and spraying gas through the device to measure its sensitivity. If the detector does not alarm, its sensitivity is considered weak; if it alarms, its sensitivity is considered strong. However, because there are many types of gas / fire detectors, and each type requires a different type of gas, a separate detection instrument is needed for each type of detector. This results in significant production costs. Furthermore, carrying multiple detection instruments during each testing trip is time-consuming and laborious. Utility Model Content

[0004] The technical problem this invention aims to solve is: to address the issue that existing detection devices can only detect the sensitivity of one type of detector, resulting in high production costs and the time-consuming and labor-intensive process of carrying multiple detection devices for each test. This invention provides a detector sensitivity detection device that facilitates the replacement of gas cylinders. By improving the structure of the detection device, the installation and removal of the detection gas cylinder relative to the support rod can be adjusted to replace different detection gas cylinders according to different detector models, thereby reducing the overall production cost of the detection device. At the same time, it eliminates the need to carry multiple detection devices, saving time and effort.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a detector sensitivity detection device that facilitates gas cylinder replacement, comprising: a support part, a detection part, and a connecting mechanism. The detection part is installed on the support part. When the detection part senses the detector, the detection part ejects a detection instrument to detect the sensitivity of the detector. The connecting mechanism comprises: a connecting block and a snap-fit ​​block. The connecting block is installed on the detection part, and the snap-fit ​​block is installed on the support part. When the connecting block and the snap-fit ​​block are connected, the detection part is installed on the support part. When the connecting block and the snap-fit ​​block are not connected, the detection part is detached from the support part.

[0006] Therefore, the connecting mechanism enables the detachable installation and removal of the support unit and the detection unit, allowing multiple detection units to be installed on one support unit. Compared to the existing integrated design of the support unit and the detection unit, this method is simpler in structure and easier to operate. The detachable connection between the support unit and the detection unit allows for the replacement of different detection units according to different types of detectors. Thus, it is not necessary to equip each type of detector with a support unit, thereby reducing the overall cost of the detection device. At the same time, when carrying it, only one support unit is needed to perform sensitivity testing on different models of detectors, saving time and effort.

[0007] As a further improvement to the above technical solution, the support part is a telescopic rod. Therefore, the telescopic rod facilitates the support and storage of the entire detection device. During detection, the telescopic rod is in an extended state, which facilitates the testing of the detector's sensitivity. When carried, the telescopic rod is in a shortened state, which facilitates the carrying of the entire detection device.

[0008] As a further improvement to the above technical solution: a support block is provided on one side of the support part opposite to the detection part, the detection part is mounted on the support block, and the snap-fit ​​block is mounted on the support block.

[0009] As a further improvement to the above technical solution: a mounting block is provided on one side of the detection unit opposite to the support block. The support block has a mounting groove that is adapted to the mounting block. The mounting block is placed in the mounting groove so that the detection unit is mounted on the support block. The cross-sectional shape of the mounting block is polygonal, and the cross-sectional shape of the mounting groove is polygonal, thus matching the cross-sectional shape of the mounting block. Therefore, through the mutual cooperation of the mounting block and the mounting groove, the detection unit can be easily aligned and inserted into the support block, thereby facilitating the installation and disassembly of the detection unit and the support unit.

[0010] As a further improvement to the above technical solution: the detection unit includes a gas cylinder, a cap, and a gas outlet pipe. The gas cylinder is connected to the support block. A mounting block is provided on one side of the gas cylinder opposite to the support block. The connecting block is mounted on the gas cylinder. The gas cylinder is used to store the gas required for detector detection. The cap is mounted on the gas cylinder, and the gas outlet pipe passes through the cap, with one end of the cap inserted into the gas cylinder. Thus, the detection gas stored in the gas cylinder is blown into the detection end of the detector using the gas outlet pipe, thereby using this gas to detect the sensitivity of the detector.

[0011] As a further improvement to the above technical solution, the bottle cap is embedded with a proximity sensor. Therefore, during detection, the gas outlet pipe can only expel the gas stored in the gas cylinder when the proximity sensor emits a signal, so that the gas can act on the detector to be sensitively tested.

[0012] As a further improvement to the above technical solution: a pump and a solenoid valve are connected in series in the gas outlet pipe. Thus, the pump provides power to extract gas from the gas cylinder, and the solenoid valve opens and closes the gas outlet pipe.

[0013] As a further improvement to the above technical solution: the detection unit further includes a switch, a controller, and a battery. The proximity sensor, the pump, the solenoid valve, and the switch are all connected to the controller, and the proximity sensor, the pump, the solenoid valve, the switch, and the controller are all connected to the battery. Thus, the controller controls the proximity sensor, the pump, the solenoid valve, and the switch, thereby controlling the operating status of the entire detector sensitivity detection device; the battery provides power to the entire detector sensitivity detection device.

[0014] As a further improvement to the above technical solution, it also includes an annular baffle, which is threadedly connected to the support block and located outside the detection unit. Therefore, during detection, the annular baffle ensures that the detector to be sensitive and the detector itself are in a sealed state, preventing the required detection gas from evaporating. This improves the detection accuracy and efficiency of the detector sensitivity detection.

[0015] As a further improvement to the above technical solution: a groove is formed on the side of the annular baffle away from the support block, and a rubber pad is embedded in the groove. Thus, since the detector is placed on the roof, and there are obstructions such as pipes around the detector to be sensitively tested on the roof, the groove and the rubber pad work together to ensure that the side of the annular baffle away from the support block abuts against the roof. The obstructions such as pipes are placed in the groove and abut against the rubber pad, thereby avoiding a gap between the side of the annular baffle away from the support block and the roof, which would prevent the detector to be sensitively tested and the detector itself from being in a sealed state.

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

[0017] 1. This utility model enables the detachable installation and disassembly of the support unit and the detection unit through a connecting mechanism, allowing multiple detection units to be installed on one support unit. Compared with the existing design of the support unit and detection unit as a set, this method has a simple structure and is easy to operate. Through the detachable connection between the support unit and the detection unit, different detection units can be replaced according to different types of detectors. Thus, there is no need to equip each type of detector with a support unit. By reducing the number of support units, the overall cost of the detection device is reduced. At the same time, when carrying it, only one support unit is needed to realize the sensitivity detection of different models of detectors, saving time and effort.

[0018] 2. This utility model uses a telescopic rod to facilitate the support and storage of the entire detection device. During detection, the telescopic rod is in an extended state, which facilitates the detection of the detector's sensitivity. When carrying, the telescopic rod is in a shortened state, which facilitates the carrying of the entire detection device.

[0019] 3. During detection, this utility model uses an annular baffle to ensure that the detector to be tested and the detector are in a sealed state, which can prevent the gas required for the detector to be tested from evaporating. In this way, the detection accuracy and detection efficiency of the detector sensitivity detection can be improved.

[0020] 4. This utility model ensures that the side of the annular baffle away from the support block abuts against the roof through the cooperation of the groove and the rubber pad. Obstacles such as pipes are placed in the groove and abut against the rubber pad, thereby avoiding the gap between the side of the annular baffle away from the support plate and the roof, which would prevent the detector to be sensitive from being in a sealed state.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0036] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figures 1 to 5 The diagram shows the preferred embodiment of this utility model. The detector sensitivity detection device for easy replacement of gas cylinders in this embodiment includes: a support part 1, a detection part 2, and a connecting mechanism 3. The detection part 2 is installed on the support part 1. When the detection part 2 senses the detector, it ejects a detection instrument to detect the sensitivity of the detector. The connecting mechanism 3 includes: a connecting block 301 and a locking block 302. The connecting block 301 is installed on the detection part 2, and the locking block 302 is installed on the support part 1. When the connecting block 301 and the locking block 302 are connected, the detection part 2 is installed on the support part 1. When the connecting block 301 and the locking block 302 are not connected, the detection part 2 is detached from the support part 1. Therefore, the connecting mechanism 3 enables the detachable installation and removal of the support unit 1 and the detection unit 2, allowing multiple detection units 2 to be installed on one support unit 1. Compared to the existing design where the support unit 1 and the detection unit 2 are designed as a set, this method is simple in structure and easy to operate. Through the detachable connection between the support unit 1 and the detection unit 2, different detection units 2 can be replaced according to different types of detectors. Thus, it is not necessary to equip each type of detector with a support unit 1. By reducing the number of support units 1, the overall cost of the detection device is reduced. At the same time, when carrying the device, the sensitivity of different models of detectors can be tested by carrying only one support unit 1, saving time and effort.

[0039] In other words, different types of detectors require different detection gases for sensitivity testing (e.g., methane detectors require methane, hydrogen sulfide detectors require hydrogen sulfide, and carbon monoxide detectors require carbon monoxide). Existing technology uses the support unit 1 and the detection unit 2 in a paired manner, meaning each detection unit 2 is fixedly connected to its corresponding support unit 1. This requires carrying multiple detection devices. However, this application uses a connecting mechanism 3 (connecting block 301 and snap-fit ​​block 302) to achieve a detachable connection between the detection unit 2 and the support unit 1. Thus, only one support unit 1 needs to be carried, along with multiple detection units 2. This reduces the overall cost of the detection device by reducing the number of support units 1, and saves time and effort by requiring only one support unit 1.

[0040] In this embodiment, the support part 1 is a telescopic rod; a support block 101 is provided on the side of the support part 1 opposite to the detection part 2, the detection part 2 is mounted on the support block 101, and the snap-fit ​​block 302 is mounted on the support block 101. Thus, the telescopic rod facilitates the support and storage of the entire detection device. During detection, the telescopic rod is in an extended state, which facilitates the detection of the detector's sensitivity. When carried, the telescopic rod is in a shortened state, which facilitates the carrying of the entire detection device.

[0041] In this embodiment, a mounting block 201 is provided on one side of the detection unit 2 opposite to the support block 101. The support block 101 has a mounting groove 102, which is adapted to the mounting block 201. The mounting block 201 is placed in the mounting groove 102 so that the detection unit 2 is mounted on the support block 101. The cross-sectional shape of the mounting block 201 is polygonal, and the cross-sectional shape of the mounting groove 102 is polygonal, thus matching the cross-sectional shape of the mounting block 201. Therefore, through the mutual cooperation of the mounting block 201 and the mounting groove 102, it is easy for the detection unit 2 to be aligned and inserted into the support block 101, thereby facilitating the installation and removal of the detection unit 2 and the support unit 1.

[0042] In this embodiment, the detection unit 2 includes: a gas cylinder 202, a cap 203, an outlet pipe 204, a switch 208, a controller 209, and a battery 210. The gas cylinder 202 is connected to the support block 101. A mounting block 201 is provided on one side of the gas cylinder 202 opposite to the support block 101. A connecting block 301 is installed on the gas cylinder 202. The gas cylinder 202 is used to store the gas required for detection by the detector. The cap 203 is installed on the gas cylinder 202. The outlet pipe 204 passes through the cap 203, and one end of the cap 203 is inserted into the gas cylinder 202. A proximity sensor 205 is embedded in the cap 203. A pump 206 and a solenoid valve 207 are connected in series in the outlet pipe 204. The proximity sensor 205, pump 206, solenoid valve 207, and switch 208 are all connected to the controller 209. The proximity sensor 205, pump 206, solenoid valve 207, switch 208, and controller 209 are all connected to the battery 210. Therefore, the gas stored in the gas cylinder 202 is blown into the detection end of the detector through the gas outlet pipe 204, and the sensitivity of the detector is detected by this gas. During detection, the gas stored in the gas cylinder 202 can only be blown out through the gas outlet pipe 204 when the proximity sensor 205 sends a signal, so as to act on the detector whose sensitivity is to be detected. The pump 206 provides power to extract the gas from the gas cylinder 202, and the solenoid valve 207 opens and closes the gas outlet pipe 204. The controller 209 controls the proximity sensor 205, the pump 206, the solenoid valve 207, and the switch 208, thereby controlling the operation of the entire detector sensitivity detection device. The battery 210 provides power for the operation of the entire detector sensitivity detection device.

[0043] In this embodiment, an annular baffle 4 is further included. The annular baffle 4 is threadedly connected to the support block 101 and is located outside the detection unit 2. A groove 401 is provided on the side of the annular baffle 4 away from the support block 101, and a rubber pad 402 is embedded in the groove 401. Thus, during detection, the annular baffle 4 ensures that the detector to be sensitive and the detector are in a sealed state, preventing the gas required for detection from evaporating. This improves the detection accuracy and efficiency of the detector sensitivity detection. Since the detector is placed on the roof, there are obstacles such as pipes around the detector to be sensitive on the roof. The groove 401 and the rubber pad 402 work together to ensure that the side of the annular baffle 4 away from the support block 101 abuts against the roof. The obstacles such as pipes are placed in the groove 401 and abut against the rubber pad 402, thereby preventing a gap between the side of the annular baffle 4 away from the support block and the roof, which would prevent the detector to be sensitive and the detector from being in a sealed state.

[0044] In other words, by using the annular baffle 4 to ensure that the detector to be sensitive and the detector are in a sealed state, the ejected gas only evaporates within this sealed environment and does not evaporate outward, that is, it always flows around the detector. In this way, the detection accuracy and detection efficiency of the detector sensitivity detection can be improved.

[0045] The detection process of the detector sensitivity of this utility model is as follows: First, a support part 1 and a detection part 2 are moved to the position of the detector to be tested. Next, a gas cylinder 202 matching the type of detector to be tested is selected. Then, the gas cylinder 202 is installed on the support block 101 through the connecting mechanism 3, and the annular baffle 4 is installed on the support block 101. At this time, the telescopic rod is in a shortened state. Finally, the switch 208 is pressed, and the telescopic rod is extended so that the annular baffle 4 abuts against the roof, and the detector to be tested, the gas cylinder 202, are in the sealed space between the roof, the annular baffle 4, and the support block 101. At this time, the proximity sensor 205 senses the detector, the controller 209 controls the pump 206 to start and the solenoid valve 207 to open, so that the gas stored in the gas cylinder 202 is ejected and acts on the detector. If the detector alarms, it indicates that the detector sensitivity is good (i.e., the working condition is normal). If the detector does not alarm, it indicates that the detector is damaged or the sensitivity is weak.

[0046] In summary, this utility model, through the connecting mechanism 3, enables the detachable installation and disassembly of the support part 1 and the detection part 2, allowing multiple detection parts 2 to be installed on one support part 1. Compared to the existing design where the support part 1 and detection part 2 are designed as a set, this method is simpler in structure and easier to operate. The detachable connection between the support part 1 and the detection part 2 allows for the replacement of different detection parts 2 according to different types of detectors. Thus, it is unnecessary to equip each type of detector with a support part 1, reducing the overall cost of the detection device. Furthermore, when carrying the device, only one support part 1 is needed to perform sensitivity testing on different detector models, saving time and effort. The telescopic rod facilitates the support and storage of the entire detection device. During testing, the telescopic rod is in an extended state. This design facilitates the testing of detector sensitivity. When carried, the telescopic rod is in a shortened state, making the entire testing device easy to carry. During testing, the annular baffle 4 ensures that the detector and its corresponding sensor are in a sealed state, preventing the required gas from evaporating. This improves the accuracy and efficiency of the sensitivity test. The groove 401 and rubber pad 402 work together to ensure that the side of the annular baffle 4 furthest from the support block 101 abuts against the roof. Obstacles such as pipes are placed within the groove 401 and abut against the rubber pad 402, preventing gaps between the side of the annular baffle 4 furthest from the support block and the roof, which would otherwise prevent the detector and its corresponding sensor from being in a sealed state.

Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
