Description

Technical Field

[0001] The invention relates to the technical field of aerosol detection, and in particular to an aerosol concentration detector. Background Art

[0002] Aerosol concentration detector is an instrument used to measure the concentration of aerosols in the air. It is mainly used in environmental protection, public health, manufacturing, mining and construction engineering. Its working principle is to use the laser scattering principle to irradiate the light beam generated by the laser transmitter into the air to be tested. The particles will scatter the light and be collected and measured by the sensor, thereby obtaining the mass concentration of the particles in the air.

[0003] Some existing detectors are inconvenient to place when used in outdoor environments when long-term testing is required, and the height is not easy to adjust. At the same time, they cannot be placed stably on uneven ground, affecting the progress of the testing work. Some other detectors lack protective measures and are used in some construction site environments. They are easily affected by external factors and are prone to tipping over and collision, which poses a risk of damage to the detector. Summary of the invention

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows: An embodiment of the present invention provides an aerosol concentration detector, comprising: Detector; A placing device, which is fixedly mounted on the lower surface of the detector to achieve stable placement of the detector when it is in use, facilitating the detection work; The protective device is fixedly installed on the side wall of the detector to protect the detector and prevent the detector from being damaged.

[0006] Through the above technical solution, the placement device can stably place and adjust the height of the detector when it is in use, which is convenient for the detection work; the protective device protects the detector to reduce the risk of damage caused by tipping over during operation of the detector in some environments.

[0007] Furthermore, the placing device includes a placing plate, which is slidably connected to the lower surface of the detector, and a base plate is horizontally arranged at the bottom of the placing plate, and sliding grooves are provided on the relatively close sides of the placing plate and the base plate, and the inner walls of the two groups of the sliding grooves are slidably connected with moving blocks, and the moving blocks are rotatably connected with a fork arm strut, and the side walls of the moving blocks are slidably connected with a connecting bolt, and the circumferential outer wall of the connecting bolt is threadedly connected with a connecting sleeve, and the connecting bolt passes through the side walls of the moving block and the fork arm strut and is connected to the connecting sleeve, and the fork arm strut connects the two groups of moving blocks, and the side walls of a group of the moving blocks on the base plate are fixedly connected with a locking pile, and the circumferential outer wall of the locking pile is threadedly connected with a locking sleeve, and the upper surface of the base plate is provided with a locking groove, and the locking pile passes through the locking groove and is connected with the locking sleeve.

[0008] Through the above technical solution, when testing is required, the placement plate is pulled up on the base plate, and the fork arm strut is stretched together, driving the moving block to move on the sliding groove, which is convenient for height adjustment. The locking pile is locked with the locking sleeve on the locking groove to lock the pulling height.

[0009] Furthermore, the side wall of the placement plate is fixedly connected with a fixed block, the side walls of the placement plate and the detector are provided with square grooves, the inner wall of the square groove is slidably connected with a fixed tongue, the circumferential outer wall of the fixed tongue away from the placement plate is slidably connected with a return spring, the side wall of the fixed tongue away from the placement plate is fixedly connected with an blocking sleeve, the fixed tongue penetrates the side wall of the fixed block and is connected with the blocking sleeve, and the return spring is located between the fixed block and the fixed tongue.

[0010] Through the above technical solution, the blocking sleeve is pulled on the locking block to drive the fixed tongue to move, thereby releasing the connection with the detector and compressing the reset spring at the same time.

When facing some uneven ground, the height of the support feet can be adjusted to adapt to the ground, thereby maintaining the stable placement of the detector and facilitating the detection of the detector.

[0022] The present invention protects the detector through the protective device, and reduces the damage to the detector when it is hit or tipped over in some complex environments due to external factors, thereby improving the durability of the instrument. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 As shown, an embodiment of the present invention provides an aerosol concentration detector, comprising: Detector 1; a placing device 2, which is fixedly mounted on the lower surface of the detector 1 to achieve stable placement of the detector 1 when in use, facilitating detection work; a protective device 3, which is fixedly mounted on the side wall of the detector 1 to protect the detector 1 and prevent the detector 1 from being damaged.

[0027] like Figures 1 to 4As shown, the placing device 2 includes a placing plate 201, which is slidably connected to the lower surface of the detector 1, and a base plate 203 is horizontally arranged at the bottom of the placing plate 201. The placing plate 201 and the base plate 203 are both provided with sliding grooves 209 on the relatively close sides. The inner walls of the two groups of sliding grooves 209 are slidably connected with moving blocks 204, and the moving blocks 204 are rotatably connected with the fork arm support rod 202. The side wall of the moving block 204 is slidably connected with a connecting bolt 205, and the circumferential outer wall of the connecting bolt 205 is threadedly connected with a connecting sleeve 206. The connecting bolt 205 penetrates the side walls of the moving block 204 and the fork arm support rod 202 and is connected to the connecting sleeve 206. The fork arm support rod 202 connects the two groups of moving blocks 204, and the side wall of a group of moving blocks 204 on the base plate 203 is fixed. The locking pile 207 is connected to the base plate 203, and the circumferential outer wall of the locking pile 207 is threadedly connected with a locking sleeve 208. A locking groove 210 is opened on the upper surface of the base plate 203, and the locking pile 207 penetrates the locking groove 210 and is connected with the locking sleeve 208. When the inspection work is needed, the plate 201 is pulled up and placed on the base plate 203, so that it drives the fork arm support rod 202 to stretch, and drives the moving block 204 to move on the moving groove 209 to adjust the height. The locking pile 207 is locked on the locking groove 210 and the locking sleeve 208 to lock the fork arm support rod 202, so as to fix the adjusted height. The arrangement of the connecting bolt 205 and the connecting sleeve 206 allows the fork arm support rod 202 to be quickly disassembled and installed, which is convenient for the fork arm support rod 2 02 is replaced and installed after being damaged. The side wall of the placement plate 201 is fixedly connected with a fixing block 211. The placement plate 201 and the side walls of the detector 1 are provided with square grooves. The inner wall of the square groove is slidably connected with a fixing tongue 212. The outer circumferential wall of the fixing tongue 212 away from the placement plate 201 is slidably connected with a reset spring 213. The side wall of the fixing tongue 212 away from the placement plate 201 is fixedly connected with a blocking sleeve 214. The fixing tongue 212 penetrates the side wall of the fixing block 211 and is connected with the blocking sleeve 214. The reset spring 213 is between the fixing block 211 and the fixing tongue 212. When the detector 1 needs to be repaired and analyzed, the blocking sleeve 214 is pulled on the fixing block 211 to drive the fixing tongue 212 to separate from the square groove on the side wall of the detector 1. In addition to locking the detector 1, the fixed tongue 212 compresses the reset spring 213 while moving. After being released, the fixed tongue 212 is pushed to reset under the reaction force of the compression of the reset spring 213, and the detector 1 is locked. The blocking sleeve 214 prevents the fixed tongue 212 from escaping from the fixed block 211. The lower surface of the base plate 203 is fixedly installed with a support foot 215, and the circumferential outer wall of the support foot 215 is threadedly connected with a support foot sleeve 216. When facing some uneven ground, the support foot sleeve 216 can be rotated on the support foot 215 at four positions to adjust the four positions to different heights, so as to adapt to the ground and ensure the stability of the placement of the detector 1. The upper surface of the base plate 203 is fixedly connected with a blocking block 217, and a buffer pad is glued on the top of the blocking block 217.The blocking block 217 prevents the placement plate 201 and the base plate 203 from being squeezed too tightly when the fork arm support rod 202 is retracted, thereby damaging the fork arm support rod 202 and the moving block 204. The buffer pad prevents the bottom of the placement plate 201 from being worn.

[0028] In the embodiment of the present invention, when it is necessary to perform a detection work, the placement plate 201 is pulled up on the base plate 203, so that it drives the fork arm support rod 202 to stretch, and drives the moving block 204 to move on the moving groove 209 to adjust the height. At the same time, the locking pile 207 is locked on the locking groove 210 and the locking sleeve 208, so that the adjusted height is fixed. When the detector 1 needs to be repaired and analyzed, the blocking sleeve 214 is pulled on the fixing block 211, so that it drives the fixing tongue 212 to separate from the square groove on the side wall of the detector 1, and at the same time, the fixing tongue 212 is pressed. The reset spring 213 is retracted to unlock the detector 1. After the blocking sleeve 214 is released, the fixed tongue 212 is pushed to reset under the reaction force of the compression of the reset spring 213, and the detector 1 is locked, so that the detector 1 can be quickly disassembled and installed. The blocking sleeve 214 prevents the fixed tongue 212 from escaping from the fixed block 211. At the same time, when facing some uneven ground, the support foot sleeves 216 are rotated on the support feet 215 at four positions, and the heights are adjusted respectively to obtain better ground contact to adapt to the ground, thereby ensuring stable placement.

When the device topples over or collides, the buffer plate 304 receives the impact and drives the buffer column 303 to move backward in the buffer column 301, while compressing the buffer spring 302. Under the reaction force of the compression of the buffer spring 302, the impact is offset and weakened, thereby reducing the damage to the detector 1. The buffer plate 304 is internally slidably connected with a sub-plate 305, and a pull-out groove is provided on the side wall of the buffer plate 304. A positioning pile 306 is fixedly connected to the side wall of the sub-plate 305. The circumferential outer wall of the positioning pile 306 is threadedly connected with a positioning sleeve 307. The positioning pile 306 passes through the pull-out groove and is connected with the positioning sleeve 307. The sub-plate 305 is pulled out, and the position of the sub-plate 305 is fixed by the positioning pile 307 and the positioning sleeve 307, so as to protect the front and rear of the detector 1, avoid direct contact and collision between the front and back of the detector 1, and reduce the risk of damage. A top plate 308 is fixedly installed on the upper surface of the buffer plate 304, and the top plate 308 provides certain protection for the top of the detector 1.

[0030] In the embodiment of the present invention, when the device topples over or collides, the buffer plate 304 receives the impact, driving the buffer column 303 to move backward in the buffer column 301 and compressing the buffer spring 302. The buffer spring 302 offsets and weakens the impact under the reaction force of contraction, thereby protecting the detector 1.
