Description

Technical Field

[0001] The present invention relates to the technical field of temperature detection, and in particular to a fire scene temperature gradient detection patch. Background Art

[0002] In today's society, fires pose a serious threat to the safety of life and property. Effective monitoring and assessment of fire scenes are crucial. When a fire occurs, the temperature distribution at the scene presents complex gradient changes, with great temperature differences in different areas and rapid evolution over time. Accurately grasping temperature gradient information is crucial for the scientific implementation of fire rescue operations, the precise investigation of fire causes, and the optimization of fire prevention measures. In order to overcome the above-mentioned shortcomings of the existing technology and meet the actual needs of fire scene temperature gradient detection, the development of a new type of fire scene temperature gradient detection patch has urgent practical significance.

[0003] Currently, existing detection patches are all pasted on the detection area with adhesive backing. In industrial fire monitoring, equipment maintenance, process adjustment and other scenarios require temporary changes to the temperature measurement points. However, since the adhesive backing patches cannot be pasted repeatedly, the cost of use increases and the practicality and flexibility of the patches are reduced. Summary of the Invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a solution to the problem that the existing detection patches are all pasted on the detection area with adhesive backing, and the temperature measurement point cannot be temporarily changed because the adhesive backing patch cannot be pasted repeatedly.

[0005] Technical solution: A fire scene temperature gradient detection patch includes a fixed frame, the inner side wall of the fixed frame is provided with a detection patch body, the upper surface of the inner side wall of the fixed frame is provided with a through-type insertion port, the insertion port is provided with a pull plate inside, and the lower surface of the pull plate is fixedly connected to the upper surface of the detection patch body;

[0006] A fixing plate is fixedly connected to the outer side wall of the fixing frame, and a front surface of the fixing plate is provided with a plurality of through-type fixing holes.

[0007] Furthermore, a control box is fixedly connected to the inner lower surface of the fixing frame, an embedding groove is provided on the upper surface of the control box, and the lower surface of the detection patch body extends to the inside of the embedding groove.

[0008] Furthermore, the detection patch body includes a signal transmission layer, a sensor array layer is provided in front of the signal transmission layer, and a high-temperature resistant protective layer is provided in front of the sensor array layer.

[0009] Furthermore, the control box is symmetrically provided with a control cavity inside, the interior of each of the two control cavities is slidably connected to a piston plate 1, the lower surfaces of the two piston plates 1 are rotatably connected to screws, the bottom ends of the two screws extend to the bottom of the fixed frame and are fixedly connected to a dial plate, and a positioning box is fixedly connected to the left and right sides of the interior of the fixed frame and in front of the detection patch body, and the interiors of the two control cavities are fixedly connected to a U-shaped connecting pipe.

[0010] Furthermore, the interiors of the two positioning boxes are integrally formed with sliding cavities, and the ends of the two U-shaped connecting tubes away from the two control cavities are respectively connected to the interiors of the two sliding cavities, and the interiors of the two sliding cavities are slidably connected with piston plates 2, and the rear surfaces of the two piston plates 2 are fixedly connected with clamping blocks, and the rear surfaces of the two clamping blocks are fixedly connected with anti-slip layers, and the rear surfaces of the two anti-slip layers are in contact with the front surface of the detection patch body.

[0011] Furthermore, the upper surface of the pull plate is symmetrically fixedly connected with protrusions.

[0012] Beneficial effects: The present invention completely solves the problem of traditional adhesive patches not being able to be re-pasted through modular structural design. The mechanical connection system between the fixing frame and the fixing plate can be adapted to various installation accessories such as expansion screws and clamps through the fixing holes, achieving rapid fixation in multiple scenarios and avoiding the problem of adhesive failure due to high temperature.

[0013] The plug-in design of the pull plate and the insertion port allows the detection patch to be easily removed and replaced within the fixed frame. Combined with the circuit docking structure of the control box embedded slot, it ensures the stability of data transmission during patch migration. The layered design of the sensor array layer, signal transmission layer and high-temperature resistant protective layer not only ensures temperature measurement accuracy but also improves environmental adaptability.

[0014] The screw and piston transmission mechanism in the control box adjusts the pressure of the anti-slip layer of the clamping block on the patch body through the dial to achieve mechanical clamping and fixation to avoid loosening caused by thermal expansion and contraction. Compared with adhesive-backed pasting, this structure is reusable, the point replacement time is shortened, the completeness of dynamic monitoring data is improved, and the cost of consumables is reduced. It provides reliable technical support for real-time tracking of temperature gradients at fire scenes and rescue decisions. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figures 1-4 As shown, a fire scene temperature gradient detection patch is provided, comprising a fixing frame 1, an inner side wall of the fixing frame 1 being provided with a detection patch body 2, an upper surface of the inner side wall of the fixing frame 1 being provided with a through-type insertion opening 3, an interior of the insertion opening 3 being provided with a pull plate 4, the lower surface of the pull plate 4 being fixedly connected to the upper surface of the detection patch body 2; a fixing plate 5 being fixedly connected to the outer side wall of the fixing frame 1, a front surface of the fixing plate 5 being provided with a plurality of through-type fixing holes 6;

[0024] The detection patch body 2 can be installed in multiple scenarios through the cooperation of the fixing frame 1 and the fixing plate 5. During installation, the adapter accessories are selected according to the scenario and passed through the fixing hole 6 of the fixing plate 5 to fix the fixing plate 5 at the target position. Then the detection patch body 2 is inserted from the insertion port 3 of the fixing frame 1 through the pull plate 4. When the point needs to be changed later, the pull plate 4 is pulled out to pull out the detection patch body 2, and a new fixing plate 5 is replaced or it is directly installed in the fixing frame 1 at the new position. In this way, flexible switching of installation methods can be achieved through the modular structure, which is convenient for rapid deployment at the fire scene. At the same time, the fixing structure is reusable, and the detection patch body 2 can be migrated across scenarios, which not only reduces costs but also improves dynamic monitoring efficiency, and solves the problem that traditional adhesive-backed patches have large installation limitations and cannot be reused.

[0025] like Figure 1 and Figure 5 As shown, the inner lower surface of the fixing frame 1 is fixedly connected to the control box 7, the upper surface of the control box 7 is provided with an embedding groove 8, and the lower surface of the detection patch body 2 extends to the inside of the embedding groove 8;

[0026] The control box 7 on the lower surface of the interior of the fixed frame 1 cooperates with the lower surface of the detection patch body 2 through the embedding groove 8 on the upper surface. During installation, after the detection patch body 2 is inserted into the insertion port 3, its lower surface is precisely embedded in the embedding groove 8, ensuring that the detection patch body 2 is accurately positioned, so that the detection patch body 2 can focus on temperature detection. The two form functional complementarity through the embedded connection, which not only simplifies the patch body structure and improves high temperature resistance, but also facilitates later maintenance and reduces overall maintenance costs.

[0027] like Figure 3 and Figure 4 As shown, the detection patch body 2 includes a signal transmission layer 201, a sensor array layer 202 is provided in front of the signal transmission layer 201, and a high temperature resistant protective layer 203 is provided in front of the sensor array layer 202;

[0028] The signal transmission layer 201 of the detection patch body 2 is designed with conductive ink or flexible circuit, which can convert the temperature signal collected by the sensor array layer 202 into an electrical signal. The sensor array layer 202 integrates a micro thermocouple or thermistor array, which can sense the temperature in real time and form gradient data. The high-temperature resistant protective layer 203 is composed of ceramic coating or aramid fiber, which can withstand high temperatures of 800-1200°C, protecting the internal sensors and circuits from flames and high-temperature corrosion. The protective layer resists the harsh external environment, the sensor layer accurately measures temperature, and the signal transmission layer 201 stably outputs data, ensuring efficient operation in the complex environment of the fire scene.

[0029] like Figure 1-Figure 5 As shown, the control box 7 has a symmetrical control chamber 9, and the interiors of the two control chambers 9 are slidably connected to piston plates 10. The lower surfaces of the two piston plates 10 are rotatably connected to screws 11. The bottom ends of the two screws 11 extend to the bottom of the fixed frame 1 and are fixedly connected to a dial 12. The left and right sides of the interior of the fixed frame 1 and in front of the detection patch body 2 are fixedly connected to a positioning box 13. The interiors of the two control chambers 9 are fixedly connected to a U-shaped connecting pipe 14.

[0030] The interiors of the two positioning boxes 13 are integrally formed with a sliding cavity 15, and the ends of the two U-shaped connecting tubes 14 away from the two control cavities 9 are respectively connected to the interiors of the two sliding cavities 15. The interiors of the two sliding cavities 15 are slidably connected to piston plates 16. The rear surfaces of the two piston plates 16 are fixedly connected to abutment blocks 17. The rear surfaces of the two abutment blocks 17 are fixedly connected to anti-slip layers 18. The rear surfaces of the two anti-slip layers 18 are in contact with the front surface of the detection patch body 2.

[0031] The piston plate 10 in the symmetrical control chamber 9 in the control box 7 is connected to the dial plate 12 through a screw 11. When the dial plate 12 is rotated, the screw 11 drives the piston plate 10 to slide in the control chamber 9, and transmits the pressure to the sliding chamber 15 of the positioning box 13 through the U-shaped connecting tube 14, pushing the piston plate 2 16 to drive the pressing block 17 to move backward, so that the anti-slip layer 18 is tightly pressed against the front surface of the detection patch body 2. The rough surface of the anti-slip layer 18 increases the friction force, avoids the patch from loosening, and improves the reliability and stability of the patch after installation. At the same time, the detection patch body 2 can be recovered by rotating the dial plate 12 in the opposite direction at a later stage, thereby improving its practicality.

[0032] like Figure 1 、 Figure 3 and Figure 4 As shown, the upper surface of the pull plate 4 is symmetrically fixedly connected with a protrusion 19;

[0033] The protrusions 19 symmetrically arranged on the upper surface of the pull plate 4 can provide force points by pinching with fingers or hooking with tools, making it convenient for the operator to quickly plug and unplug the pull plate 4 and realize the installation and disassembly of the detection patch body 2. The symmetrical design of the protrusions 19 ensures uniform force when pulling, avoiding the pull plate 4 from tilting and getting stuck, and cooperates with the guide structure of the insertion port 3 to make the plugging and unplugging process smoother.

[0034] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
