Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a temperature detection structure for a fire extinguisher pressure sensor. Background Technology

[0002] A fire extinguisher pressure sensor is an important device that can capture the gas pressure information inside a fire extinguisher in real time based on the pressure changes inside the fire extinguisher, and transmit this information to various components of the fire extinguisher to enable the fire extinguisher to start instantly.

[0003] In fire extinguisher pressure sensors, the design of the temperature detection structure is a crucial aspect, as it is essential for ensuring the accuracy and stability of the sensor under different ambient temperatures.

[0004] However, traditional pressure sensors used in fire extinguishers require staff to use a measuring instrument to inspect them during temperature detection, which involves a lot of troubleshooting. There is also a large gap between the probe and the contact surface, which can easily lead to inaccurate temperature detection results. This can cause problems with the sensor to go undetected in time, posing a safety hazard. Utility Model Content

[0005] This utility model discloses a temperature detection structure for a fire extinguisher pressure sensor, aiming to solve the technical problem that when performing temperature detection, staff need to hold the detector to check it, which requires a lot of effort. There is also a large gap between the detector probe and the contact surface, which can easily lead to inaccurate temperature detection results and cause sensor problems to go undetected in time, posing a safety hazard.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A temperature detection structure for a fire extinguisher pressure sensor includes a fire extinguisher body, a sensor body, and a pressure gauge connected to an outer wall of one side of the sensor body, and further includes:

[0008] Mounting mechanism: The mounting mechanism is set on the outer wall of the sensor body. The outer wall of the sensor body is provided with a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are hinged to each other. A fixing plate is provided on one side of the outer wall of the first clamping plate and the second clamping plate. Mounting holes are opened on the outer walls of the two fixing plates. Screws are provided on the inner walls of the mounting holes. Temperature sensing components are provided on the outer walls of the first clamping plate and the second clamping plate on the side away from the fixing plate.

[0009] Display mechanism: The display mechanism is disposed on the outer circumferential wall of the pressure gauge.

[0010] In this case, a first clamping plate and a second clamping plate are provided on the outer wall of the sensor body. The two are hinged to each other to facilitate angle adjustment. Two fixing plates are then connected by screws to fix the entire temperature detection structure to the outer wall of the sensor body. The detection area is large, and the two are in close contact with each other. The temperature is detected by two sets of temperature sensing components, which can be compared to make the temperature detection results more accurate. This allows for timely detection of abnormalities, such as excessively high temperatures, so that timely measures can be taken to prevent the fire extinguisher from being unusable or causing danger in emergency situations.

[0011] In a preferred embodiment, the temperature sensing component includes a thermal pad. Assembly grooves are formed on the outer walls of both the first and second clamping plates on the side away from the fixing plate. A plurality of thermopile assemblies are arranged at equal intervals on the bottom inner wall of the assembly grooves. A thermal plate is connected to one outer wall of each thermopile assembly, and the thermal pad is disposed on one outer wall of the thermal plate.

[0012] The heat-conducting plate is made of graphene, which can sensitively sense temperature changes. The heat-conducting pad is placed on the outermost side and is made of thermally conductive silicone. It can be used to connect the sensor body and the heat-conducting plate together. Its soft texture can be squeezed to fill the gap between the heat-conducting plate and the sensor body, making them fit more tightly and ensuring the accuracy of temperature detection. Finally, the detected temperature is effectively transferred to the thermopile assembly, which converts it into an electrical signal for output.

[0013] In a preferred embodiment, the display mechanism includes a fixing sleeve disposed on the outer circumferential wall of the pressure gauge, a plurality of equally spaced breathing lights being disposed on the top outer wall of the fixing sleeve, and a display screen being disposed on the top outer wall of the fixing sleeve.

[0014] The fixing sleeve is set on the outer circumference of the pressure gauge, and the display screen on its top outer wall can clearly display the temperature data of the sensor body, so that users can quickly understand the current status of the fire extinguisher. The design of the breathing light allows users to see the status of the fire extinguisher intuitively from a distance, so as to take timely countermeasures. For example, when the pressure gauge temperature is too high, the breathing light will emit a red alarm to remind the user to check or replace it.

[0015] As described above, a temperature detection structure for a fire extinguisher pressure sensor includes a fire extinguisher body, a sensor body, and a pressure gauge connected to one outer wall of the sensor body. It further includes: a mounting mechanism: the mounting mechanism is disposed on the outer wall of the sensor body, and a first clamping plate and a second clamping plate are disposed on the outer wall of the sensor body. The first clamping plate and the second clamping plate are hinged to each other. A fixing plate is disposed on one outer wall of each of the first and second clamping plates. Mounting holes are opened on the outer walls of the two fixing plates, and screws are disposed on the inner walls of the mounting holes. A temperature sensing component is disposed on the outer wall of each of the first and second clamping plates away from the fixing plates. A display mechanism: the display mechanism is disposed on the circumferential outer wall of the pressure gauge. The temperature detection structure for a fire extinguisher pressure sensor provided by this utility model has the technical effect of improving the accuracy and stability of temperature detection results.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The temperature detection structure for a fire extinguisher pressure sensor disclosed in this utility model is mainly used in scenarios where temperature detection requires staff to hold a detector to check it, which involves a lot of troubleshooting. There is a large gap between the detector probe and the contact surface, which can easily lead to inaccurate temperature detection results. This can result in the sensor malfunctioning and not being detected in time, posing a safety hazard.

[0025] Reference Figure 1 , Figure 2 and Figure 4 A temperature detection structure for a fire extinguisher pressure sensor includes a fire extinguisher body 1, a sensor body 4, and a pressure gauge 2 connected to the outer wall of one side of the sensor body 4, and further includes:

[0026] Mounting mechanism: The mounting mechanism is set on the outer wall of the sensor body 4. The outer wall of the sensor body 4 is provided with a first clamping plate 5 and a second clamping plate 9. The first clamping plate 5 and the second clamping plate 9 are hinged to each other. A fixing plate is provided on one side of the outer wall of the first clamping plate 5 and the second clamping plate 9. Mounting holes are opened on the outer walls of the two fixing plates. Screws 7 are provided on the inner walls of the mounting holes. Temperature sensing components are provided on the outer walls of the first clamping plate 5 and the second clamping plate 9 on the side away from the fixing plates.

[0027] Display mechanism: The display mechanism is located on the outer circumference of pressure gauge 2.

[0028] In a specific embodiment, a first clamping plate 5 and a second clamping plate 9 are provided on the outer wall of the sensor body 4. The two are hinged to each other to facilitate angle adjustment. The two fixing plates are then connected by screws 7 to fix the entire temperature detection structure to the outer wall of the sensor body 4. The detection area is large and the two are in close contact with each other. The temperature is detected by two sets of temperature sensing components, and the results can be compared to make the temperature detection results more accurate. Abnormal situations, such as excessively high temperatures, can be detected in time, so that measures can be taken in time to avoid the fire extinguisher being unusable or dangerous in an emergency.

[0029] Reference Figure 1 , Figure 5 and Figure 6 In a preferred embodiment, the temperature sensing component includes a heat-conducting pad 10. The first clamping plate 5 and the second clamping plate 9 are both provided with assembly grooves on the outer wall of the side away from the fixing plate. A plurality of thermopile assemblies 12 are arranged at equal intervals on the bottom inner wall of the assembly groove. A heat-conducting plate 13 is connected to one side outer wall of the thermopile assembly 12. The heat-conducting pad 10 is disposed on one side outer wall of the heat-conducting plate 13.

[0030] The first clamping plate 5 and the second clamping plate 9 are used together.

[0031] The heat-conducting plate 13 is made of graphene, which can sensitively sense temperature changes. The heat-conducting pad 10 is placed on the outermost side and is made of thermally conductive silicone. It can be used to connect the sensor body 4 and the heat-conducting plate 13 together. Its soft texture can be squeezed to fill the gap between the heat-conducting plate 13 and the sensor body 4, making them fit more tightly and ensuring the accuracy of temperature detection. Finally, the detected temperature is effectively transferred to the thermopile assembly 12. These thermopile assemblies 12 are connected in series and convert the temperature into an electrical signal for output.

[0032] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the display mechanism includes a fixing sleeve 3, which is disposed on the outer circumference of the pressure gauge 2. A plurality of breathing lights 8 are disposed on the top outer wall of the fixing sleeve 3 at equal intervals, and a display screen 11 is disposed on the top outer wall of the fixing sleeve 3. The diameter of the inner circumference of the fixing sleeve 3 is the same as the diameter of the outer circumference of the pressure gauge 2.

[0033] The fixing sleeve 3 is set on the outer circumference of the pressure gauge 2. The display screen 11 on its top outer wall can clearly display the temperature data of the sensor body 4, so that the user can quickly understand the current status of the fire extinguisher. The design of the breathing light 8 allows the user to see the status of the fire extinguisher intuitively from a distance, so as to take timely countermeasures. For example, when the temperature of the pressure gauge 2 is too high, the breathing light 8 will emit a red alarm to remind the user to check or replace it.

[0034] Reference Figure 3 and Figure 4 In a preferred embodiment, a connecting line 6 is provided on the bottom outer wall of the fixing sleeve 3, and one end of the connecting line 6 is connected to the thermopile assembly 12.

[0035] The thermopile assembly 12 transmits the converted electrical signals to the fixing sleeve 3 via the connecting line 6, and finally displays them on the display screen 11. It should be noted that when the electrical signals output by the thermopile assembly 12 on the first clamping plate 5 and the second clamping plate 9 are inconsistent, the breathing light 8 will also automatically alarm.

[0036] Reference Figure 1 and Figure 2 In a preferred embodiment, the sensor body 4 is disposed on the outer wall of the fire extinguisher body 1 at the bottle opening. The bottle opening is one of the areas most sensitive to changes in internal pressure of the fire extinguisher. Placing the sensor here can more accurately reflect the internal pressure state of the fire extinguisher.

[0037] Working principle: When in use, first attach the fixing sleeve 3 to the outer circumference of the pressure gauge 2, then clamp the first clamping plate 5 and the second clamping plate 9 to the outer wall of the sensor body 4, and finally tighten the screw 7 to fix it. When the sensor body 4 is running, the temperature generated will be transferred to the thermopile assembly 12 through the heat-conducting pad 10 and the heat-conducting plate 13. The thermopile assembly 12 is made of two different metals connected together. If one end is heated, the charge will accumulate at both ends, generating a potential difference. Finally, the electrical signal is processed and displayed as data on the display screen 11. When the voltmeter temperature is too high, the breathing light 8 will emit a red alarm to remind the user to check or replace it.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
