The comprehensive sampling device is an environmental monitoring device specifically designed for collecting samples of air particulate matter in the atmosphere, and it uses the filter membrane weighing method to capture particulate matter.
[0003] Existing integrated sampling devices typically require manual handling by staff, making them time-consuming and labor-intensive to carry. Furthermore, existing portable integrated sampling devices lack shock-absorbing structures, making them susceptible to damage from bumps when traversing uneven terrain. Utility Model Content

[0005] The technical solution of this utility model is as follows: A comprehensive air particulate matter sampling device includes a housing and movable wheels. Four movable wheels are installed on the lower side of the housing. A push rod is installed on one of the two sides of the housing. The device also includes an electric push rod, a movable plate, a support frame, a cylinder, a partition, a support column, a particulate sampler, a buffer plate, and a buffer mechanism. Two electric push rods are arranged on the inner bottom wall of the housing. The electric push rods are connected to an external power source via cables. The two electric push rods are arranged symmetrically. A movable plate is provided at the telescopic end of each electric push rod. The movable plate moves synchronously with the telescopic end of the electric push rod. The support frame is installed... A cylinder is mounted on the upper side of the moving plate and the upper side of the support frame. A switch valve is connected to the outer side of the cylinder. The support frame and the cylinder move synchronously with the moving plate. A partition is installed inside the cylinder. A support column is inserted into the upper side of the cylinder and can move vertically inside the cylinder. A particle sampler is mounted on the upper side of the support column. A buffer plate is mounted at the bottom end of the support column. The buffer plate has multiple water passage holes. The particle sampler and the buffer plate move synchronously with the support column. Multiple buffering mechanisms are provided on the cylinder. The buffering mechanisms are used to buffer the support column.
[0006] The buffer mechanism includes compression blocks, buffer rods, arc-shaped plates, and springs. Four compression blocks are connected to the outside of the support column via four connecting rods. The four compression blocks are arranged in a ring on the outside of the support column. Four buffer rods are inserted into the outside of the cylinder. The buffer rods can move horizontally inside the cylinder. The arc-shaped plates are installed on the inner ends of the buffer rods and move synchronously with the buffer rods. The springs are sleeved on the buffer rods, and the two ends of the springs are connected to the cylinder and the arc-shaped plates, respectively.
[0007] As a preferred embodiment of the air particulate matter comprehensive sampling device of this utility model, in order to buffer the vibration force received by the particulate sampler, the shape of the extrusion block is a frustum shape that is wider at the top and narrower at the bottom, and the shape of the arc plate is adapted to the shape of the extrusion block.

[0010] As a preferred embodiment of the air particulate matter comprehensive sampling device of this utility model, in order to achieve buffering between the housing and the particulate sampler and avoid collision between the housing and the particulate sampler, four buffer pads are provided on the lower side of the particulate sampler, and the four buffer pads are symmetrically arranged on the lower side of the particulate sampler.
[0011] The working principle and beneficial effects of this utility model are as follows:
[0012] In contrast to existing integrated sampling devices, which are inconvenient for staff to carry and prone to damage from bumps during movement, this invention addresses these issues. Through the combination of a cylinder, partitions, support columns, a buffer plate, and water placed inside the cylinder, vertical damping and vibration reduction of the particle sampler's vibrations during movement are achieved. The support columns and buffer mechanism work together to achieve horizontal damping and vibration reduction of the particle sampler's vibrations during movement. This multi-stage damping and vibration reduction reduces the impact of vibrations during movement on the particle sampler, lowering the probability of damage from bumps and ensuring the normal operation of the particle sampler. Furthermore, the combination of an electric push rod and a moving plate allows for the rapid deployment or folding of the support and sampling mechanisms, reducing the overall size of the device and making it easier for staff to carry.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0021] like Figures 1-4As shown, this embodiment proposes an integrated air particulate matter sampling device, including a housing 1 and four wheels 2. The housing 1 has four wheels 2 mounted on its lower side. It also includes an electric push rod 3, a moving plate 4, a support frame 5, a cylinder 6, a partition 7, a support column 8, a particulate sampler 9, a buffer disc 10, and a buffer mechanism. Compared to existing integrated sampling devices that are inconvenient for workers to carry and prone to damage from bumps during movement, this embodiment addresses these issues by utilizing the cylinder 6, partition 7, support column 8, buffer disc 10, and water placed inside the cylinder 6 to effectively manage the impact on the particulate sampler 9 during movement. The vertical buffering and vibration reduction of the vibration force is achieved through the cooperation of the support column 8 and the buffering mechanism, which realizes the horizontal buffering and vibration reduction of the vibration force received by the particle sampler 9 during the movement. This achieves multi-level buffering and vibration reduction of the particle sampler 9, reduces the impact of the vibration force generated during the movement on the particle sampler 9, reduces the probability of damage caused by the bumps during the movement of the device, and ensures the normal application of the particle sampler 9. Through the cooperation of the electric push rod 3 and the moving plate 4, the support mechanism and the sampling mechanism can be quickly deployed or stored, reducing the overall size of the device and making it convenient for staff to carry the device.
[0022] like Figure 2 As shown, two electric push rods 3 are provided on the inner bottom wall of the housing 1. The two electric push rods 3 are arranged symmetrically. The telescopic end of the electric push rod 3 is provided with a movable plate 4. T-shaped plates 11 are installed on both sides of the inner wall of the housing 1. T-shaped grooves are opened on both sides of the movable plate 4. The width of the T-shaped grooves is adapted to the width of the T-shaped plate 11. The T-shaped plate 11 can limit the movement of the movable plate 4, thereby ensuring the stability of the movable plate 4 when it moves. Figure 1 As shown, the support frame 5 is installed on the upper side of the movable plate 4, the upper side of the support frame 5 is equipped with a cylinder 6, the support column 8 is inserted into the upper side of the cylinder 6, the upper side of the support column 8 is equipped with a particle sampler 9, and four buffer pads are provided on the lower side of the particle sampler 9. The four buffer pads are symmetrically arranged on the lower side of the particle sampler 9. The buffer pads can buffer the shell 1 and the particle sampler 9, avoiding direct collision between the shell 1 and the particle sampler 9. The cooperation of the electric push rod 3 and the movable plate 4 can realize the rapid unfolding or storage of the support mechanism and the sampling mechanism, thereby reducing the overall volume of the device and making it easier for staff to carry the device.
[0023] like Figure 3As described, a baffle 7 is installed inside the cylinder 6. Water is added to the bottom of the cylinder 6 through a switch valve. A buffer plate 10 is installed at the bottom of the support column 8. The cooperation between the support column 8 and the buffer plate 10 allows the buffer plate 10 to squeeze the water inside the cylinder 6. The water can buffer the force on the buffer plate 10, thereby achieving vertical buffering and vibration reduction of the particle sampler 9. Multiple buffering mechanisms are provided on the cylinder 6. Multiple through holes are opened on the upper side of the cylinder 6. The inner diameter of the through holes is adapted to the outer diameter of the connecting rod. When the support column 8 moves vertically due to vibration, the support column 8 drives the connecting column to move inside the through holes. Figure 4 The buffer mechanism shown includes a squeezing block 101, a buffer rod 102, an arc plate 103, and a spring 104. The squeezing block 101 is shaped like a frustum, wider at the top and narrower at the bottom. The arc plate 103 is shaped to match the squeezing block 101. When the squeezing block 101 moves downward, its special shape can push the arc plate 103 to move outward, causing the arc plate 103 to compress the spring 104. This allows the spring 104 to provide horizontal buffering and vibration reduction for the particle sampler 9. The buffer mechanism can provide horizontal buffering and vibration reduction for the vibration force on the support column 8, thereby achieving multi-stage buffering and vibration reduction for the particle sampler 9 and enhancing the vibration reduction effect of the particle sampler 9.
[0024] Working principle:
[0025] When the device needs to be moved, the staff pushes the moving wheel 2 with the push rod. The moving wheel 2 moves the device. When the device passes through an uneven area, the device vibrates due to the bumps. The support column 8 moves downward under the action of the vibration force. The support column 8 drives the buffer plate 10 and the squeezing block 101 to move downward. The buffer plate 10 squeezes the water inside the cylinder 6. The squeezed water flows out through the water passage. The water buffers the buffer plate 10, realizing the vertical buffering of the vibration force on the particle sampler 9. When the squeezing block 101 moves, it pushes the arc plate 103 to move outward. The arc plate 103 compresses the spring 104. The spring 104 buffers the arc plate 103, realizing the horizontal buffering of the vibration force on the particle sampler 9. This achieves multi-level buffering and shock absorption of the vibration force on the particle sampler 9.
[0026] After moving to the appropriate position, the electric push rod 3 is activated. The telescopic end of the electric push rod 3 extends and pushes the moving plate 4 upward. The moving plate 4 drives the cylinder 6 upward through the support frame 5. The support frame 5 drives the particle sampler 9 upward through the support column 8, thereby realizing the adjustment of the height of the particle sampler 9. After the height is adjusted, the staff uses the particle sampler 9 to sample the particulate matter in the air.
[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
