Description

Technical Field

[0001] This utility model relates to the field of fire detection probe technology, specifically a double-layer cyclone image fire detection probe. Background Technology

[0002] The working principle of a fire detector is to determine the presence of a flame by monitoring the intensity and frequency of the flame in the furnace. These detectors typically use infrared or ultraviolet sensors to detect light of a specific wavelength emitted by the burning flame, and then identify the flame based on its radiation characteristics and flashing frequency. Once a flame is detected, the detector sends a signal to the control system to ensure that the fire is detected in time and that necessary measures are taken.

[0003] Existing fire detector probes only rely on simple airflow to cool the probe during use, which is insufficient to create targeted convective cooling. Consequently, they cannot effectively reduce the temperature inside the main gun barrel, which can easily damage the internal detection probe.

[0004] Therefore, a dual-layer cyclone imaging fire detection probe is urgently needed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer cyclone image fire detection probe, including a gun barrel and a mounting rod disposed at one end of the gun barrel, wherein a detection probe is provided at the end of the mounting rod away from the gun barrel, and further includes a cooling component disposed in the gun barrel for targeted convection cooling of the detection probe;

The first sleeve is sleeved around the mounting rod, and a first drain tube is fixedly connected to the inner wall of the side near the mounting rod. Multiple first drain plates are fixedly connected to the side wall of the first drain tube. A second sleeve is sleeved on the side wall of the first sleeve. One end of the second sleeve is connected to the gun barrel. A second drain tube is fixedly connected to the inner wall of the second sleeve near the first sleeve. Multiple second drain plates are fixedly connected to the side wall of the second drain tube. Multiple first guide holes are opened on the side wall of the first sleeve away from the gun barrel. The gun barrel is provided with a driving assembly for driving the second sleeve. A transparent protective plate is fixedly connected to the end of the second sleeve near the detection probe. The gun barrel is provided with a cleaning assembly for cleaning the transparent protective plate at the detection end of the detection probe. An air inlet connection pipe is fixedly connected to the side wall of the gun barrel.

[0007] The cleaning assembly includes a cleaning tube disposed on the side of the gun barrel near the detection probe. The cleaning tube is sleeved on the side wall of the second sleeve. Multiple third guide plates are fixedly connected to the inner wall of the cleaning tube on the side near the second sleeve. Multiple second guide holes are opened on the side wall of the second sleeve on the end near the gun barrel.

[0008] A conical guide shield is fixedly connected to one end of the cleaning tube near the transparent protective plate.

[0009] The drive assembly includes a drive rod rotatably connected to the barrel, a gear fixedly connected to one end of the drive rod, a drive ring fixedly connected to the end of the cleaning tube away from the conical guide cover, the drive ring rotatably connected to the side wall of the barrel, and a gear ring fixedly connected to the end of the drive ring away from the cleaning tube. The gear ring meshes with the gear, and the barrel is provided with a rotating assembly for rotating the drive rod.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1-6 The double-layer cyclone image fire detector probe shown in the figure includes a gun barrel 101 and a mounting rod 102 disposed at one end of the gun barrel 101. The end of the mounting rod 102 away from the gun barrel 101 is provided with a detection probe. It also includes a cooling component disposed in the gun barrel 101 for targeted convection cooling of the detection probe.

[0024] The cooling assembly includes a first sleeve 201 fixedly connected to the side of the gun barrel 101 near the mounting rod 102. The first sleeve 201 is sleeved around the mounting rod 102, and a first drain pipe 202 is fixedly connected to the inner wall of the side near the mounting rod 102. A plurality of first drain plates 203 are fixedly connected to the side wall of the first drain pipe 202. A second sleeve 205 is sleeved on the side wall of the first sleeve 201. One end of the second sleeve 205 is connected to the gun barrel 101, and a second drain plate 203 is fixedly connected to the inner wall of the second sleeve 205 near the first sleeve 201. The second drain tube 206 has multiple second drain plates 207 fixedly connected to its side wall. The first sleeve 201 has multiple first guide holes 204 on its side wall away from the gun barrel 101. The gun barrel 101 is provided with a drive assembly for driving the second sleeve 205. The second sleeve 205 is fixedly connected to a transparent protective plate 209 at its end near the detection probe. The gun barrel 101 is provided with a cleaning assembly for cleaning the transparent protective plate 209 at the detection end of the detection probe. An air inlet connection pipe 210 is fixedly connected to the side wall of the gun barrel 101.

[0025] It should be noted that by setting up the cooling components, a double-helix airflow barrier is formed by using a double-layer cyclone airflow. The first layer of cyclone is close to the mounting rod 102 and directly cools the detection probe. The second layer of cyclone forms a heat insulation layer on the outside, preventing the high temperature of the furnace from being conducted into the gun barrel 101. This significantly increases the contact area and disturbance intensity between the airflow and the detection probe and the inner wall of the gun barrel 101. Compared with the traditional single airflow blowing, this improves the cooling effect on the detection probe.

[0026] It is worth noting that the specific structure and working principle of the fire detector probe are already known to those in the field, and will not be elaborated further here.

[0027] Please see Figure 1 , Figure 2 and Figure 5 The cleaning assembly shown in the figure includes a cleaning tube 301 disposed on the side of the gun barrel 101 near the detection probe. The cleaning tube 301 is sleeved on the side wall of the second sleeve 205. Multiple third guide plates 302 are fixedly connected to the inner wall of the cleaning tube 301 near the second sleeve 205. Multiple second guide holes 304 are opened on the side wall of the second sleeve 205 near the gun barrel 101. A conical guide cover 303 is fixedly connected to the end of the cleaning tube 301 near the transparent protective plate 209.

[0028] It should be noted that by setting up the cleaning component, dust, soot, and other impurities on the surface of the transparent protective plate 209 can be flung out along the tangential direction, preventing contaminants from obstructing the detection light path, thereby improving the detection quality of multiple flames by the detection probe.

[0029] Please see Figure 5 and Figure 6 The driving assembly shown in the figure includes a driving rod 401 rotatably connected to the barrel 101. One end of the driving rod 401 is fixedly connected to a gear 402. The end of the cleaning tube 301 away from the conical guide cover 303 is fixedly connected to a driving ring 403. The driving ring 403 is rotatably connected to the side wall of the barrel 101. The end of the driving ring 403 away from the cleaning tube 301 is fixedly connected to a gear ring 404. The gear ring 404 is meshed with the gear 402. The barrel 101 is provided with a rotating assembly for rotating the driving rod 401.

[0030] It should be noted here that the drive component is configured to rotate the cleaning pipe 301, thereby causing the spiral airflow to generate centrifugal force.

[0031] Working principle: When using the modified fire detector probe, first install the gun barrel 101 on the furnace wall, and then use the detection probe to detect the flame inside the furnace. During the detection process, use infrared or ultraviolet sensors to detect the light of a specific wavelength emitted by the burning flame, and then identify the flame based on the radiation characteristics and flashing frequency of the flame. Once the flame is detected, the probe will send a signal to the control system to ensure that the fire is detected in time and the necessary measures are taken.

[0032] Furthermore, during flame detection, the detection probe delivers external high-pressure airflow from the inlet connection pipe 210 into the gun barrel 101, and then flows into the first sleeve 201. After the high-pressure airflow flows into the first sleeve 201, a first guide pipe 202 is fixed on the inner wall of the first sleeve 201 near the mounting rod 102. Multiple first guide plates 203 on its side wall guide the high-pressure airflow through the first guide plates 203. Guided by their tilt angle, the high-pressure airflow is forced to rotate around the axis of the mounting rod 102, forming a first layer of cyclone airflow. The rotating airflow passes through multiple first guide holes 20 on the distal side wall of the first sleeve 201. 4. The airflow is sprayed into the second sleeve 205. Similarly, under the guidance of the tilt angle of each second guide plate 207, it is forced to rotate around the axis of the first sleeve 201, thereby forming a second layer of cyclone airflow. Therefore, the double-helix airflow barrier formed by the double-layer cyclone airflow significantly increases the contact area and disturbance intensity between the airflow and the detection probe and the inner wall of the gun barrel 101. At the same time, the first layer of cyclone is close to the mounting rod 102 and directly cools the detection probe. The second layer of cyclone forms a heat insulation layer on the outside, preventing the high temperature of the furnace from being conducted into the gun barrel 101. Compared with the traditional single-flow blowing, the cooling effect on the detection probe is improved.

[0033] Furthermore, the rotating airflow within the second sleeve 205 will flow from each of the second guide holes 304 to the cleaning tube 301. Simultaneously, the coordinated action of the drive assembly and the rotating assembly causes the cleaning tube 301 to rotate. Therefore, under the rotation of the cleaning tube 301, the guiding effect of the tilt angle of each of the third guide plates 302, and the guiding effect of the conical guide cover 303, the spiral airflow generates a centrifugal force effect, which can throw out dust, soot, and other impurities on the surface of the transparent protective plate 209 along the tangential direction, preventing contaminants from blocking the detection light path, thereby improving the detection quality of the multi-flame detection probe.

[0034] Example 2

[0035] Please see Figure 6This embodiment further illustrates Example 1. The rotating assembly shown in the figure includes a fixed box 501 fixedly connected to the inner wall of the barrel 101. A rotating rod 502 is rotatably connected inside the fixed box 501. The rotating rod 502 is connected to the drive rod 401. Multiple rotating blades 503 are fixedly connected to the side wall of the rotating rod 502. The side of the fixed box 501 near the detection probe is connected to the first sleeve 201 through an air outlet pipe 504. An air inlet pipe 505 is fixedly connected to the side of the fixed box 501 away from the detection probe. A conical sleeve 506 is fixedly connected to the end of the air inlet pipe 505 away from the fixed box 501. The air inlet pipe 505 and the rotating rod 502 are eccentrically arranged.

[0036] It should be noted that, due to the arrangement of the rotating assembly, when the external high-pressure airflow flows from inside the barrel 101, it will be guided by the conical sleeve 506 and enter the fixed box 501 through the air inlet pipe 505. Since the air inlet pipe 505 and the rotating rod 502 are eccentrically set, the high-speed airflow will impact the surface of the rotating blade 503 on the side wall of the rotating rod 502, thereby driving the rotating rod 502 to rotate, which in turn drives the gear 402 at one end of the drive rod 401 to rotate. The airflow after impacting the rotating blade 503 will flow into the first sleeve 201 from the air outlet pipe 504.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
