Description

Technical Field

[0001] The utility model relates to the technical field of environmental comprehensive sampling boxes, and specifically relates to an environmental impact assessment comprehensive sampling box. Background Technique

[0002] The environmental impact comprehensive sampling box, also known as the environmental impact comprehensive sampler, usually conducts air sampling through dust and the atmosphere, and is composed of a chassis, a sampling head, a sampling slot, a display screen, a keyboard, an interface, sampling bottles, etc. During the sampling process, the sampling bottles are directly sampled by connecting air pipes and the sampling head. After sampling and filtering through the internal components of the chassis, the environmental impact assessment data is obtained on the display screen, and it is widely used in the fields of environmental protection, industry, and health and epidemic prevention.

[0003] The above-mentioned and existing related technologies often have the following defects: when a person moves the chassis by lifting, the sampling bottles are generally placed on the bracket on one side of the chassis. However, the bracket structure is relatively simple and can only simply place the sampling bottles. When the chassis shakes, the sampling bottles will also shake in the bracket and collide with the bracket, which not only reduces the service life of the sampling bottles, but also increases the use cost of the environmental impact assessment comprehensive sampling.

[0004] Therefore, we propose an environmental impact assessment comprehensive sampling box. Content of the Utility Model

A display screen is installed on one side of the chassis. A keyboard is installed at a position on the chassis below the display screen. An interface is opened at a position on the chassis below the keyboard. A limiting structure is provided on one side of the chassis. The limiting structure includes a U-shaped plate. One side of the U-shaped plate is fixedly connected to the chassis. Slide holes are opened at positions on the upper surface of the U-shaped plate corresponding to several sampling bottles.

[0010] Preferably, a circular tube is fixedly connected to one side of the side plate close to the limiting block, and the arc surface of the long tube is slidably connected to the inner wall of the circular tube.

[0014] Preferably, shock-absorbing pads are fixedly connected to the inner walls of several arc grooves, and the inner walls of the shock-absorbing pads are abutted against the sampling bottles.

[0015] The effects achieved by the above components are as follows: The sampling bottle moves into the arc groove of the limiting block and fits with the shock-absorbing pad, and the shock-absorbing pad achieves the effect of providing a certain buffer during the placement of the sampling bottle.

[0016] Preferably, a shielding structure is provided on one side of the chassis. The shielding structure includes a rotating frame. One side of the rotating frame is fixedly connected to the chassis.

DETAILED DESCRIPTION

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0030] Please refer to Figure 1 and Figure 2 , the present invention provides a technical solution: an environmental impact assessment comprehensive sampling box, including a chassis 1 and a plurality of sampling bottles 7. A sampling head 2 is installed on the upper surface of the chassis 1. Two sampling slots 3 are opened at a position on the upper surface of the chassis 1 on one side of the sampling head 2. A display screen 4 is installed on one side of the chassis 1. A keyboard 5 is installed at a position on the chassis 1 below the display screen 4. An interface 6 is opened at a position on the chassis 1 below the keyboard 5. A limiting structure 8 is provided on one side of the chassis 1, achieving the effect of limiting the multiple sampling bottles 7 of the environmental impact assessment comprehensive sampling box, thereby minimizing the problem that the sampling bottles 7 are simply placed in the bracket and may be damaged due to knocking in the bracket when the operator takes the chassis 1 and causes the chassis 1 to shake. A shielding structure 9 is provided on one side of the chassis 1, achieving the effect of shielding the position of the sampling bottles 7 on one side of the chassis 1. After shielding the sampling bottles 7 with the cooperation of various components, not only can the direct contact between the placed items and the sampling bottles 7 be avoided, but also the sampling bottles 7 can be prevented from being exposed to strong sunlight during external use, thereby improving the practicality of the device.

[0031] Next, the specific settings and functions of its limiting structure 8 and shielding structure 9 will be specifically described.

[0032] As Figure 2 and Figure 3 and Figure 4 shown, the limiting structure 8 includes a U-shaped plate 801. One side of the U-shaped plate 801 is fixedly connected to the chassis 1. Slide holes 802 are opened at positions on the upper surface of the U-shaped plate 801 corresponding to the plurality of sampling bottles 7. Limiting blocks 803 are fixedly connected to the inner walls of the U-shaped plate 801 corresponding to the plurality of sampling bottles 7. Arc grooves 804 are opened on the inner walls of the limiting blocks 803. Two side plates 805 are fixedly connected to the inner wall of the U-shaped plate 801. A long tube 806 slidably penetrates through the inner walls of the two side plates 805. A magnet 807 is fixedly connected to the arc surface of the long tube 806. One side of the magnet 807 is attracted to the side plate 805. The surface of the sampling bottle 7 is slidably connected to the inner wall of the slide hole 802. The arc surface of the long tube 806 is slidably connected to the surface of the sampling bottle 7. One end of the long tube 806 is fixedly connected to a pull rod 812. Moving the pull rod 812 drives the magnet 807 to disengage from the side plate 805 through the long tube 806. The pull rod 812 plays a better role in pulling the long tube 806.

[0033] On one side of the side plate 805 close to the limit block 803, a circular tube 808 is fixedly connected. The arc surface of the long tube 806 is slidably connected to the inner wall of the circular tube 808. The long tube 806 slides from the inner wall of the circular tube 808 through the side plate 805. The circular tube 808 achieves the effect of restricting the movement path of the long tube 806. A positioning hole 810 is formed in the arc surface of the circular tube 808. A positioning rod 811 is fixedly connected to the arc surface of the long tube 806. The arc surface of the positioning rod 811 is slidably connected to the inner wall of the positioning hole 810. The long tube 806 drives the positioning tube to move to the inner wall of the positioning hole 810. The positioning hole 810 plays a role in temporarily positioning the long tube 806 after it is pulled out. The inner walls of several arc grooves 804 are all fixedly connected with shock pads 809. The inner wall of the shock pad 809 abuts against the sampling bottle 7. The sampling bottle 7 moves into the arc groove 804 of the limit block 803 and fits with the shock pad 809. The shock pad 809 achieves the effect of providing a certain buffer during the placement of the sampling bottle 7.

[0034] As Figure 2 and Figure 5 shown, the shielding structure 9 includes a rotating frame 91. One side of the rotating frame 91 is fixedly connected to the chassis 1. The rotating frame 91 is located above the U-shaped plate 801. A baffle 92 is rotatably connected to the surface of the rotating frame 91. The cross-section of the baffle 92 is in an "L" shape. A counterweight bar 93 is fixedly connected to the short arm of the baffle 92. The lower surface of the counterweight bar 93 abuts against the U-shaped plate 801. The baffle 92 is located on the surfaces of several sampling bottles 7. The long arm of the baffle 92 abuts against the chassis 1. An edge hole 94 is formed in the short arm of the baffle 92. By means of the edge hole 94, the baffle 92 is rotated. The edge hole 94 plays a role in facilitating the rotation of the baffle 92 with the counterweight bar 93 by personnel.

[0035] Working principle: When comprehensive sampling of air environmental impact assessment is required, first move the chassis 1 to the sampling position. The U-shaped plate 801 drives the sampling bottle 7 in the sliding hole 802 through the chassis 1. The side plate 805 limits the long tube 806 on the surface of the sampling bottle 7 through the U-shaped plate 801 with the help of the magnet 807, so that the sampling bottle 7 is limited in the arc groove 804 of the limiting block 803 by the long tube 806. When the chassis 1 shakes during movement, the long tube 806 is in close contact with the sampling bottle 7 to prevent the sampling bottle 7 from shaking by itself. After moving to the sampling position, cancel the shielding of the sampling bottle 7 through the shielding structure 9, and then drive the long tube 806 to move away from the side plate 805 by the pull rod 812. The pull rod 812 plays a better role in pulling the long tube 806. The magnet 807 is separated from the side of the side plate 805 through the long tube 806. After the long tube 806 slides out from the inner wall of one side plate 805 and then separates from the surface of the sampling bottle 7, at this time, the long tube 806 sliding in the round tube 808 drives the positioning rod 811 to move. The round tube 808 achieves the effect of restricting the movement path of the long tube 806. The arc surface of the positioning rod 811 fits with the inner wall of the positioning hole 810. The positioning hole 810 plays a role in temporarily positioning the long tube 806 after it is pulled out. Then take out the sampling bottle 7. The sampling bottle 7 separates from the shock pad 809 in the arc groove 804 and then separates from the inner wall of the sliding hole 802. The shock pad 809 provides a certain buffer effect during the placement of the sampling bottle 7. Finally, place it in the sampling slot 3. After connecting the air pipe to the chassis 1 and the sampling bottle 7, start the display screen 4 and the chassis 1 through the keyboard 5 switch. The sampling head 2 makes a certain volume of air pass through the filter membrane of known mass at a constant speed. The particulate matter suspended in the air is retained on the filter membrane. According to the increased mass of the filter membrane and the volume of air passing through the filter membrane, the mass concentration of total suspended particulate matter in the air is determined, and it can be used to measure components such as metals, inorganic salts, and organic pollutants in the particulate matter. And part of the air enters the sampling bottle 7, and after measuring the components such as particulate matter metals in the air environment, it is displayed through the display screen 4, so as to obtain the comprehensive data of environmental impact assessment.

[0036] When the sampling bottle 7 needs to be taken out, first rotate the baffle 92 away from the U-shaped plate 801 with the help of the side hole 94. The side hole 94 plays a role in facilitating the rotation of the baffle 92 with the counterweight strip 93 by the personnel. The baffle 92 drives the counterweight strip 93 to separate from the U-shaped plate 801, and then rotates to a certain angle through the rotating frame 91 and fits with the chassis 1. At this time, the sampling bottle 7 is exposed. After canceling the limit on the sampling bottle 7 through the limiting structure 8, it can be taken out for sampling use.
