Description

Technical Field

[0001] The present invention relates to the technical field of explosive detection, and particularly to an explosive detection device. Background Art

[0002] With the need for anti-terrorism explosion work worldwide and the continuous development of science and technology, trace explosive detection technology has developed rapidly. In particular, portable explosive detection devices have received increasing attention. Public safety issues are particularly prominent in places with high population density such as subways, railways, airports, and conference venues. Portable, fast, and stable explosive detection devices provide convenience for security detection.

[0003] Publication No. CN206740758U discloses a low-power handheld explosive detector. When the ambient light intensity is high, the photoresistor becomes larger and the backlight intensity is adjusted to become smaller. When the ambient light is weak, the photoresistor becomes smaller and the backlight intensity is adjusted to become larger. This design also reduces the power consumption of the screen and saves electrical energy. By using an OLED / LCD display screen, an ultra-low-power microcontroller, and a low-power rail-to-rail operational amplifier, overall power savings can be achieved, reducing the power consumption during operation. The design is scientific and reasonable, and the lowest-power working devices are selected, which can save electrical energy well and save the economic cost during operation. It is simple and convenient to use, and has strong operational feasibility and is worthy of promotion. However, the following problems still exist in the actual use of this patent:

When the container squeezes the second rotating bracket, the second clamping plate can rotate, so that the clamping and fixing of the container can be realized. Through the relative rotation of the first clamping plate and the second clamping plate, containers with different diameters can be clamped. The radiation generated during detection can be shielded by the radiation protection cover body, so as to achieve the protection effect. The specific content is as follows:

[0022] 1. By setting up a detection mechanism, not only can the detector body be started by using the start button at the bottom of the handheld handle, thus enabling the detection of explosives. When starting the detector body, by placing an item inside the second clamping plate and making the item contact the detection probe at the end of the detection bracket, the detection of explosives can be carried out. When it is necessary to use the test bracket for radiation protection detection, the container needs to be clamped and fixed. By squeezing the container inward, the container squeezes the detection probe and the detection bracket, and at the same time, the detection bracket squeezes the connecting spring. When the second sliding block at the end of the bracket slides connected to the first sliding block, the first sliding block drives the connecting column and the pushing ball to squeeze the first spring under the action of the connecting sliding sleeve. At the same time, the pushing ball squeezes the end of the first clamping plate. Under the action of the clamping sliding rod and the clamping sliding sleeve clamped inside the first rotating bracket and the second rotating bracket, the rotation of the rotating connecting rod is realized, thus realizing the rotation of the second clamping plate. Under the elastic force of the clamping spring inside the first rotating bracket and the second rotating bracket, the relative stability of the first clamping plate and the second clamping plate can be realized. When the container squeezes the second rotating bracket, the rotation of the second clamping plate can be realized, thus realizing the clamping and fixing of the container. Through the relative rotation of the first clamping plate and the second clamping plate, containers with different diameters can be clamped, so as to adapt to a wider range of containers. At the same time, the detection of explosives can be carried out in different scenarios. When pulling the container outward, the container can be taken out from the inside of the second clamping plate, which is convenient for the detection of explosives. Under the elastic force of the positioning spring inside the placement seat, while the positioning sliding sleeve slides relative to the outside of the positioning sliding rod, the detector body is fixed by using the positioning block, which is convenient for the placement of the detector body;

[0023] 2. By setting up a radiation protection mechanism, not only can the radiation generated during detection be shielded by using the radiation protection cover, thus achieving the protection effect, but also by starting the lifting motor to drive the sprocket transmission assembly and the lifting threaded rod to rotate, the lifting threaded sleeve drives the lifting baffle to move up and down, and the radiation protection cover can be opened, which is convenient for taking and placing the container.

Detailed implementation manners

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-11 The present invention provides a technical solution: an explosive detection device, including a detection mechanism 1 and a placement seat 128 installed at the bottom of the detection mechanism 1. A radiation protection mechanism 2 is arranged on one side of the detection mechanism 1, and a locking bracket 209 is arranged on one side of the radiation protection mechanism 2. The detection mechanism 1 includes a detector body 101. A display screen 102 is fixedly installed at the top of the detector body 101. A hand-held handle 103 is fixedly installed on one side of the detector body 101. A start button 104 is arranged at the bottom of the hand-held handle 103. Among them, fixing grooves 105 are symmetrically opened at the bottom of the detector body 101. A plurality of display lights 106 are fixedly installed on one side of the top of the display screen 102. Among them, a mounting bracket 107 is fixedly installed on the side of the detector body 101 away from the hand-held handle 103. Connecting springs 108 are fixedly installed around the mounting bracket 107. A detection bracket 109 is fixedly installed at the end of the connecting spring 108. A detection probe 110 is fixedly installed on the outside of the detection bracket 109. By using the start button 104 at the bottom of the hand-held handle 103 to start the detector body 101, the detection of explosives can be realized. When starting the detector body 101, by placing an item inside the second clamping plate 122 and making the item contact the detection probe 110 at the end of the detection bracket 109, the detection of explosives can be carried out.

[0038] Inside the detection bracket 109, several connecting sliding rods 111 are fixedly installed. On the outer sides of the connecting sliding rods 111, connecting sliding sleeves 112 are symmetrically and slidably connected. On the outer sides of the connecting sliding sleeves 112, first sliding blocks 113 are fixedly installed. On one side of the connecting sliding sleeves 112, first springs 114 are fixedly installed. On one side of the first sliding blocks 113, connecting columns 115 are fixedly installed. At the ends of the connecting columns 115, pushing balls 116 are fixedly installed. In the middle of the mounting bracket 107, several pushing brackets 117 are fixedly installed. On both sides of the ends of the pushing brackets 117, second sliding blocks 118 are fixedly installed. The second sliding blocks 118 are slidably connected with the first sliding blocks 113. Around the mounting bracket 107, first rotating brackets 119 are rotatably connected. At the ends of the first rotating brackets 119, first clamping plates 120 are rotatably connected. At the ends of the first clamping plates 120, first rotating rods 121 are rotatably connected. At the ends of the first rotating rods 121, second clamping plates 122 are rotatably connected. When it is necessary to use the test bracket for anti-radiation detection, the container needs to be clamped and fixed. By squeezing the container inward, the container squeezes the detection probe 110 and the detection bracket 109. At the same time, the detection bracket 109 squeezes the connecting spring 108. When the second sliding blocks 118 at the ends of the pushing brackets 117 are slidably connected with the first sliding blocks 113, the first sliding blocks 113 drive the connecting columns 115 and the pushing balls 116 to squeeze the first spring 114 under the action of the connecting sliding sleeves 112. At the same time, the pushing balls 116 squeeze the ends of the first clamping plates 120. Under the action of the clamping sliding rods 124 and the clamping sliding sleeves 125 inside the first rotating brackets 119 and the second rotating brackets 123, the rotation of the rotating connecting rod 127 is realized, so as to realize the rotation of the second clamping plate 122. Under the elastic force of the clamping springs 126 inside the first rotating brackets 119 and the second rotating brackets 123, the relative stability of the first clamping plate 120 and the second clamping plate 122 can be realized. When the container squeezes the second rotating bracket 123, the rotation of the second clamping plate 122 can be realized, so as to realize the clamping and fixing of the container. Through the relative rotation of the first clamping plate 120 and the second clamping plate 122, containers with different diameters can be clamped, so as to adapt to a wider range of containers.

[0039] One end of the second clamping plate 122 is rotatably connected to a second rotating bracket 123. Clamping sliding rods 124 are fixedly installed inside both the second rotating bracket 123 and the first rotating bracket 119. A clamping sliding sleeve 125 is slidably connected to the outer side of the clamping sliding rod 124. A clamping spring 126 is fixedly installed on one side of the clamping sliding sleeve 125. A rotating connecting rod 127 is rotatably connected to the outer side of the clamping sliding sleeve 125. The two rotating connecting rods 127 are respectively rotatably connected to the first clamping plate 120 and the detection bracket 109. A placement groove 129 is formed at the center of the top of the placement seat 128. Positioning sliding rods 130 are symmetrically installed at the bottom of the placement seat 128 close to the placement groove 129. A positioning sliding sleeve 131 is slidably connected to the outer side of the positioning sliding rod 130. A positioning spring 132 is fixedly installed on one side of the positioning sliding sleeve 131. A positioning block 133 is fixedly installed on the top of the positioning sliding sleeve 131. The positioning block 133 is snap-fitted with the detector body 101 through the fixing groove 105. When the container is pulled outwards, the container can be taken out from the inside of the second clamping plate 122, which is convenient for the detection of explosives. Under the elastic force of the positioning spring 132 inside the placement seat 128, while the positioning sliding sleeve 131 slides relatively on the outer side of the positioning sliding rod 130, the detector body 101 is fixed by using the positioning block 133, which is convenient for the placement of the detector body 101. An intelligent sensor is arranged inside the detector body 101, specifically a fluorescence sensor. By recognizing the pattern of fluorescence change caused by the measured substance, it is judged whether there is an explosive. The fluorescence sensor does not contain a radiation source and has no radiation hazard to the human body. It has the characteristics of high detection sensitivity and long durability.

[0040] The radiation protection mechanism 2 includes a radiation protection cover body 201. On one side inside the radiation protection cover body 201, a fixed baffle 202 is fixedly installed. On one side of the top of the radiation protection cover body 201, a motor cover 203 is fixedly installed. On one side inside the motor cover 203, a lifting motor 204 is fixedly installed. The output end of the lifting motor 204 is fixedly connected to a sprocket transmission assembly 205. Symmetrically installed at the bottom of the sprocket transmission assembly 205 are lifting threaded rods 206. On the outer sides of both lifting threaded rods 206, there are lifting threaded sleeves 207. Fixedly installed on the outer side of the lifting threaded sleeve 207 is a lifting baffle 208. A locking bracket 209 is fixedly installed on one side of the radiation protection cover body 201. Fixedly installed around the inside of the locking bracket 209 are locking sliding rods 210. Slidably connected to the outer sides of the locking sliding rods 210 are locking sliding sleeves 211. On one side of the locking sliding sleeve 211, a locking spring 212 is fixedly installed. On the top of the locking sliding sleeve 211, a locking sliding plate 213 is fixedly installed. On the top of the locking sliding plate 213, a locking clamping plate 214 is fixedly installed. On one side of the middle of the locking clamping plate 214, an unlocking handle 215 is fixedly installed. On the top of the locking clamping plate 214, a opening and closing block 216 is fixedly installed. On the top of the opening and closing block 216, an opening and closing sliding groove 217 is provided. The radiation protection cover body 201 can shield the radiation generated during detection, thus achieving the protection effect. At the same time, starting the lifting motor 204 drives the sprocket transmission assembly 205 and the lifting threaded rods 206 to rotate, causing the lifting threaded sleeve 207 to drive the lifting baffle 208 to move up and down, and being able to open the radiation protection cover body 201, facilitating the taking and placing of the container. Through the locking spring 212 inside the locking bracket 209, by pulling the unlocking handle 215, the locking clamping plate 214 and the locking sliding plate 213 can be driven to slide relatively. Under the elastic force of the locking spring 212, the placing seat 128 is clamped and fixed by the locking clamping plate 214, facilitating the fixing of the detector and improving the stability during detection.

[0041] Working principle: Before using this explosive detection device, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, use the start button 104 at the bottom of the handheld handle 103 to start the detector body 101, so as to detect explosives. When starting the detector body 101, place the item inside the second clamping plate 122, and contact the detection probe 110 at the end of the detection bracket 109 through the item, so as to detect explosives. When it is necessary to use the test bracket for radiation protection detection, it is necessary to clamp and fix the container. By squeezing the container inward, the container squeezes the detection probe 110 and the detection bracket 109, and at the same time the detection bracket 109 squeezes the connecting spring 108. When the second sliding block 118 at the end of the pushing bracket 117 slides connected to the first sliding block 113, the first sliding block 113 drives the connecting column 115 and the pushing ball 116 to squeeze the first spring 114 under the action of the connecting sliding sleeve 112. At the same time, the pushing ball 116 squeezes the end of the first clamping plate 120. Under the action of the clamping sliding rod 124 and the clamping sliding sleeve 125 clamped inside the first rotating bracket 119 and the second rotating bracket 123, the rotation of the rotating connecting rod 127 is realized, so as to realize the rotation of the second clamping plate 122. Under the elastic force of the clamping spring 126 inside the first rotating bracket 119 and the second rotating bracket 123, the relative stability of the first clamping plate 120 and the second clamping plate 122 can be realized. When the container squeezes the second rotating bracket 123, the rotation of the second clamping plate 122 can be realized, so as to realize the clamping and fixing of the container.

[0042] Secondly, through the relative rotation of the first clamping plate 120 and the second clamping plate 122, containers with different diameters can be clamped, so as to adapt to a wider range of containers, and at the same time, explosives can be detected in different occasions. When pulling the container outward, the container can be taken out from the inside of the second clamping plate 122, which is convenient for detecting explosives. Under the elastic force of the positioning spring 132 inside the placing seat 128, while the positioning sliding sleeve 131 slides relative to the outside of the positioning sliding rod 130, the detector body 101 is fixed by the positioning block 133, which is convenient for placing the detector body 101.

[0043] Finally, the radiation shielding cover 201 can shield the radiation generated during detection, so as to achieve the protection effect. At the same time, start the lifting motor 204 to drive the sprocket transmission assembly 205 and the lifting threaded rod 206 to rotate, so that the lifting threaded sleeve 207 drives the lifting baffle 208 to move up and down, and the radiation shielding cover 201 can be opened, which is convenient for taking and placing the container. Through the locking spring 212 inside the locking bracket 209, the locking clamping plate 214 and the locking sliding plate 213 can be driven to slide relative to each other by pulling the unlocking handle 215. Under the elastic force of the locking spring 212, the placing seat 128 is clamped and fixed by the locking clamping plate 214, which is convenient for fixing the detector and improving the stability during detection.
