Description

Technical Field

[0001] The utility model relates to the technical field of detection instruments, in particular to a visual multifunctional detection instrument. Background Art

[0002] A detection instrument refers to an instrument that measures all fire-fighting data or conditions (such as gas composition, radioactive ray intensity, fire source, etc.) at a fire scene or rescue site through manual or automatic detection methods, such as combustible gas detectors, toxic gas detectors, life detectors, thermal imagers, etc.

[0003] When performing gas detection, a fan can be used to disturb the flow, thereby increasing the measurement range. The existing method is to install a fan on the outside of the detector to change the wind speed, but directly installing it on the outside of the detector increases the overall volume and is not easy to carry. An embedded fan can be used to reduce the overall volume. The embedded method generally involves rotating the handle end of the fan to the detector, and rotating the fan out when it is needed. However, this method can only satisfy the requirement of rotating the fan out. The blowing direction of the fan after rotating out is fixed. The blowing direction of the fan and the gas detection direction remain relatively fixed and cannot be adjusted according to actual needs. During assembly, the directions of the two will be inconsistent due to layout problems, and the gas to be detected cannot be gathered to the gas detection end as quickly as possible. In an environment where the gas needs to be detected as quickly as possible, the detection efficiency is affected, and the fan cannot be fully utilized to cooperate with gas detection, which has limitations. Utility Model Content

[0004] Based on this, it is necessary to provide a visual multifunctional detector to address the problem that the existing detector uses an embedded fan with a single activity direction and limited gas detection coordination.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A visual multifunctional detector includes a detector body with a display screen, a gas detection module is arranged on one side of the detector body, a groove is opened on the top of the detector body, and a fan module is movably connected in the groove;

[0007] The fan module includes a fan, a hinge block and a slider; the hinge block is hinged at the edge of the groove of the detector body, and the moving track is a 90° rotation range from the inside of the groove to the outside. A through hole for accommodating the handle end of the fan is opened at the center of the hinge block, and a slide groove with an arc of 180° is opened along the circumference of the through hole of the hinge block; the slider is arranged on the handle end of the fan and is located in the slide groove;

[0008] When the slider is at the end of the slide slot, the blowing direction of the fan is the same as or opposite to the detection direction of the gas detection module.

[0009] Furthermore, silicone layers for limiting positioning are provided at both ends of the slide groove of the hinge block.

[0010] Furthermore, the silicone layer includes a plurality of annular portions with different inner diameters, which are spaced from large to small along the track of the slide groove from the end of the slide groove, and two adjacent annular portions are connected as a whole through an inclined portion.

[0011] Furthermore, a baffle for shielding the fan is hingedly connected to one side of the fan facing the outside of the groove of the detector body.

[0012] Furthermore, a buckle is slidably connected to the top of the detector body and located beside the groove, a protrusion is provided in the middle of the buckle, the protrusion passes through the detector body and is located in the groove, and a slot matching the buckle is provided on the side wall of the fan. When the protrusion slides into the slot, the fan is confined in the groove.

[0013] Furthermore, a foldable handle is movably installed at the bottom of the detector body.

[0014] Furthermore, an infrared thermal imaging module, a CMOS visible light camera module, an infrared ranging module, and an infrared temperature measurement module are provided on the other side of the detector body that is symmetrical to the display screen.

[0015] Furthermore, a speaker is provided on the other side of the detector body corresponding to the gas detection module.

[0016] Furthermore, a leakage detection module for detecting 120V and above AC power is installed inside the detector body.

[0018] Compared with the prior art, the beneficial effects of the utility model include:

[0019] 1. The fan provided in the utility model can not only flip from the groove, but also rotate to adjust the angle, so as to realize the two-way adjustment of the fan, and then use the different angles of the fan to cooperate with the gas detection module for detection to meet the actual detection needs;

[0020] 2. The utility model provides a silicone pad at the end of the slide groove, which can deform the slide block when it moves to the end to limit and fix the slide block, thereby ensuring that the angle of the fan remains relatively fixed, and the inner diameter of the silicone layer gradually increases toward the end of the slide groove, gradually increasing the limit of the slide block;

[0021] 3. The utility model integrates infrared thermal imaging module, CMOS visible light camera module, infrared distance measurement module, infrared temperature measurement module, leakage detection module, communication module, gas detection module, fan module, display screen, etc. on the same detection instrument to meet the needs of visualization and multi-function, which is conducive to reasonable command in the rear according to the various data collected in the front and reduces risks.

[0033] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0034] See also Figure 1 and Figure 4 This embodiment introduces a visual multifunctional detector, including a detector body 1 with a display screen. The display screen is located on the back of the detector body 1, facing the user. Buttons such as a menu key, a confirmation key, a return key, an up key, a down key, a power key, etc. are arranged below the display screen for operating the detector. The detector body 1 is mainly composed of a shell and a built-in processor. The handle 4 is movably installed at the bottom of the detector body 1. When it is not needed to be held, the handle 4 can be bent and folded for easy carrying. The internal space of the handle 4 can also be used to store a battery pack to power the detector. The battery pack is in a detachable form, that is, a battery cover is clamped on the surface of the handle 4. The battery cover is removed to replace the battery pack.

[0035] like Figure 2 As shown, for the convenience of actual use, the sensing ends of the infrared thermal imaging module 5, the CMOS visible light camera module 6, the infrared distance measuring module 7, and the infrared temperature measuring module 8 are installed on the front of the detector body 1, that is, on the other side symmetrical to the display screen, so that it is convenient for detection when the user holds it normally. The infrared thermal imaging module 5, the CMOS visible light camera module 6, the infrared distance measuring module 7, and the infrared temperature measuring module 8 all use existing modules, and their main structures are integrated inside the detector body 1 and electrically connected, and the detected data can be displayed on the display screen.

[0036] The functions of the infrared thermal imaging module 5, the CMOS visible light camera module 6, the infrared distance measurement module 7, and the infrared temperature measurement module 8 are briefly described below. The infrared resolution of the infrared thermal imaging module 5 is 384*288 pixels; it has four color modes, and can freely switch between rainbow mode, black heat mode, white heat mode, and iron red mode according to the on-site conditions. The CMOS visible light camera module 6 has 800 pixels and supports autofocus. The infrared distance measurement module 7 adopts an infrared optical system for fast and accurate distance measurement; laser and visible light image dual auxiliary positioning; the distance measurement range is 700 meters. The infrared temperature measurement module 8 adopts a high-precision sensor with fast response; non-contact temperature measurement; laser and visible light image auxiliary positioning.

[0037] like Figure 1 and Figure 2 As shown, the gas detection module 3 and the speaker 9 are respectively located on the other two symmetrical sides of the detector body 1. The speaker 9 mainly plays the role of intelligent voice broadcasting, for example, broadcasting the measured distance, temperature and other data. The gas detection module 3 is mainly used to detect gas. The four gas sensors used in this embodiment are used for oxygen, hydrogen sulfide, carbon monoxide, and combustible gas detection. In actual application, sensors can be added and modified to meet the detection needs of actual environmental gases.

[0038] The sensor of the gas detection module 3 is built into the detector body 1 and electrically connected, and the sensing end is placed on the surface of the detector body 1. In order to reduce dust accumulation at the sensing end and protect the sensing end of the sensor, a cover plate is slidably connected to the sensing end, and a hole matching the sensing end is opened on the cover plate, and the sensing end is covered. When not detecting, the portion of the cover plate without a hole covers the sensing end. When detecting is required, the cover plate is slid to align the position with the hole on the cover plate with the sensing end for detection. The length of the cover plate slide slot can be limited so that when the cover plate slides to both ends, it is in two states of covering the sensing end and exposing the sensing end.

[0039] In order to facilitate data transmission and storage of the detector body 1, a USB interface can also be set up, and a Type-C USB data cable can be used to connect to a PC. After the PC automatically installs the driver, it can recognize the removable disk, and the video and photo storage path is in the removable disk / DCIM / ZZKJ / directory. The PC can perform operations such as viewing, copying, and deleting. In addition, a SIM card slot can be set up to cooperate with the built-in communication module to realize card insertion communication.

[0040] The communication module includes WIFI, Bluetooth and 4G transmission units. The on-site detection data can be transmitted to the back-field command center via WIFI, Bluetooth and 4G. In combination with the speaker 9, microphone and camera, voice intercom, video call and other operations can be performed. In order to further improve the safety of use, a leakage detection module for 120V and above AC detection is installed inside the detector body 1. When an AC voltage above 120V is detected, an audible and visual alarm can be issued.

[0041] like Figure 4 As shown, a groove is provided on the top of the detector body 1, and a fan module 2 is movably connected in the groove. A detachable mounting block can be provided in the groove, and the fan module 2 can be mounted on the mounting block to facilitate replacement of the fan module 2, or a convex block can be reserved in the groove to connect with the fan module 2, or a hole can be reserved in the side wall of the groove to directly connect with the fan module 2.

[0042] like Figure 4-6 As shown, the fan module 2 includes a fan 21, an articulated block 22, a slider 23, a silicone layer 24 and a baffle 25. The articulated block 22 is hingedly connected to the mounting block, or the protrusion, or the side wall of the groove. A through hole is provided in the center of the articulated block 22, and the handle end of the fan 21 passes through the through hole. Since the articulated block 22 is arranged at the edge of the groove, it is blocked by the edge of the groove. The rotation range of the articulated block 22 is 90°, that is, when the detector is held by the user, the fan 21 in the groove can be rotated from a horizontal state to a vertical state, or from a vertical state to a horizontal state, and the activity trajectory is basically 90 degrees.

[0043] A slide groove with an arc of 180° is provided along the circumference of the through hole side wall of the hinge block 22, and a slider 23 adapted to the slide groove is provided at the handle end of the fan 21. Under the restriction of the slider 23 and the slide groove, the fan 21 can rotate together with the hinge block 22, or rotate 180°. In this embodiment, the two ends of the slide groove are respectively located on the same side as the gas detection module and the speaker 9, that is, when the slider 23 slides to the end of the slide groove, the air inlet and outlet ends of the fan 21 and the detection direction of the gas detection module 3 are basically located in the same linear direction.

[0044] like Figure 7 As shown, in order to limit the slider 23 to be located at the end of the slide groove, silicone layers 24 for limiting are provided at both ends of the slide groove. The silicone layer 24 includes a plurality of circular portions with different inner diameters, which are spaced from large to small along the slide groove track starting from the end of the slide groove. Two adjacent circular portions are connected as a whole by an inclined portion. When the slider 23 moves to the position with the silicone layer 24, the limiting of the slider 23 is gradually increased by deformation and reduction of the gap.

[0045] like Figure 8As shown, when the fan 21 is located in the groove, a baffle 25 for shielding the fan 21 is hinged on one side of the fan 21 facing the outside of the groove, thereby reducing the probability of dust accumulation on the blades of the fan 21 and protecting the fan 21.

[0046] When wind speed measurement is not required, the fan 21 is located in the groove. When wind speed measurement is required, the fan 21 is rotated out of the groove. When the slider 23 is located in the middle of the slide groove, the blowing direction of the fan 21 is perpendicular to the detection direction of the gas detection module 3. When the slider 23 is at the end of the slide groove, the blowing direction of the fan 21 is the same as or opposite to the detection direction of the gas detection module 3. The horizontal angle of the fan 21 is adjusted according to actual needs. For example, if the wind speed needs to be accelerated for detection, the air intake direction of the fan 21 can be the same as the detection direction of the gas detection module 3, and the gas can be guided to the detection end of the gas detection module 3 to increase the detection speed. In addition, the fan 21 has a built-in wind speed sensor, or a wind speed sensor is set beside the fan 21 to detect the real-time wind speed. It is electrically connected to the detection instrument body 1 and is controlled by the detection instrument body 1.

[0047] To facilitate the fan 21 to rotate out of the groove, a torsion spring can be arranged at the connection between the hinge block 22 and the groove. In the initial state, the fan 21 is located outside the groove. In addition, a buckle 26 is slidably connected to the top of the detector body 1 and located beside the groove. A protrusion is arranged in the middle of the buckle 26. The protrusion passes through the detector body 1 and is located in the groove. A slot adapted to the buckle 26 is opened on the side wall of the fan 21. When the protrusion slides into the slot, the fan 21 is limited in the groove. When the buckle 26 is pushed to drive the protrusion out of the slot, the fan 21 can automatically rotate outward under the action of the torsion spring.

[0048] This embodiment integrates an infrared thermal imaging module 5, a CMOS visible light camera module 6, an infrared distance measurement module 7, an infrared temperature measurement module 8, a fan module 2, a leakage detection module, a gas detection module 3, etc. It supports multiple image modes such as taking pictures, recording, and playing back, quickly measuring the temperature and distance of objects, obtaining the ambient wind speed in real time, and whether there is leakage, real-time automatic alarm, information display and other functions, and supports Bluetooth expansion, WIFI communication and 4G full network access and other functions. It supports network voice intercom, and supports the transmission of real-time images and sensor data from the front to the command center, so that commanders can obtain the situation in the front and command firefighting more accurately. Fig. 9 The following is the overview interface displayed on the display screen, including ① status bar icons: 4G network signal strength, WIFI signal strength, extreme temperature alarm status, REC recording, system time, battery power, laser icon, etc. ② wind speed data. ③ temperature measurement data. ④ distance measurement data. ⑤ leakage detection. ⑥ four types of gas data. ⑦ button menu prompts.

[0049] In addition, the fan 21 can not only be flipped out of the groove, but also can rotate to adjust the angle, so as to achieve the dual-position adjustment of the fan 21, and then use the different angles of the fan 21 to cooperate with gas detection to meet the actual detection needs.
