DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-Figure 6A multi-directional air detection device for indoor air detection includes a box body 1 with universal wheels installed at the bottom and an air detector 2. Four groups of slide cylinders 3 are installed on the box body 1. Slide columns 4 are installed in the four groups of slide cylinders 3. The slide columns 4 are not only used to guide the support plate 5, but also to strengthen the support of the support plate 5. The four groups of slide columns 4 are fixedly installed with the support plate 5. The four groups of slide columns 4 are equidistantly distributed on the support plate 5. The support plate 5 is parallel to the upper end surface of the box body 1. A central rotating shaft 6 is rotatably installed on the support plate 5. A supporting turntable 7 for placing the air detector 2 is fixedly installed on the free end of the central rotating shaft 6.

[0019] A first mounting frame 8 is welded inside the box body 1 , and a first driving motor 9 is fixedly mounted on the first mounting frame 8 . An adjusting mechanism for controlling the lifting and lowering of the supporting plate 5 and driven by the first driving motor 9 is arranged inside the box body 1 .

[0020] The adjusting mechanism includes a driving gear 12 which is rotatably installed in the housing 1 and matched with the output end of the first driving motor 9. A nut 13 is rotatably installed on the housing 1. A screw 14 which is fixedly connected to the support plate 5 is matched with the nut 13. The rotational motion of the nut 13 is converted into the linear motion of the screw 14. The mechanism has a large transmission ratio, less wear between the two, more stable transmission, and reversibility. The screw 14 can be freely controlled to move up and down. The screw 14 is located at the center of the four groups of sliding columns 4. A driven gear 15 is fixedly installed at the bottom end of the nut 13. The outer diameter of the driven gear 15 is smaller than the outer diameter of the driving gear 12. A transmission track 16 is matched with the outside of the driving gear 12 and the driven gear 15.

[0021] A second mounting frame 33 is welded to the support plate 5 , a second drive motor 10 is welded to the second mounting frame 33 , and a steering mechanism for controlling the rotation of the turntable and driven by the second drive motor 10 is provided on the support plate 5 .

[0022] The steering mechanism includes a transmission gear 17 fixed on the central rotating shaft 6, the transmission gear 17 is arranged concentrically with the central rotating shaft 6, a transmission plate 18 is rotatably installed on the support plate 5, the transmission plate 18 is in a triangular structure, a compression spring 19 is fixedly installed on the transmission plate 18, and a protrusion that matches and conflicts with the tooth groove of the transmission gear 17 is provided at the top corner of the transmission plate 18. When the protrusion matches the tooth groove of the transmission gear 17, the transmission plate 18 will limit the position of the transmission gear 17 to prevent it from driving the central rotating shaft 6 to rotate. A contact claw 20 fixedly connected to the free end of the compression spring 19 is installed on the pin shaft on the top corner of the transmission plate 18, and a rotating wheel 21 is rotatably installed at the bottom corner of the transmission plate 18. A driving turntable 22 that is matched with the output end of the second drive motor 10 and conflicts with the rotating wheel 21 is rotatably installed on the support plate 5, and a flat surface is opened on the driving turntable 22.

[0023] A support column 11 is welded on the support turntable 7, and a mounting box 23 matched with the input end of the air detector 2 is fixedly mounted on the support column 11, and a filtering tool for screening air is arranged in the mounting box 23.

[0024] The filtering tooling includes a filter plate 24 which is mounted in a mounting box 23. The filter plate 24 is inserted into the mounting box 23 from top to bottom, and a sealing gasket is installed on the contact surface between the filter plate 24 and the mounting box 23 to prevent air leakage from affecting the detection efficiency. A collection frame 25 for collecting solid impurities in the air is slidably installed on one side of the mounting box 23.

[0025] A support cylinder 26 is fixedly installed on the other side of the installation box 23, and a pressing cylinder 27 is slidably installed in the support cylinder 26. Two groups of abutment blocks 28 are welded in the pressing cylinder 27. The two groups of abutment blocks 28 are ladder-shaped structures with opposite directions. A guide column 29 is welded on the installation box 23. A limiting column 30 matched with the collection frame 25 is slidably installed in the guide column 29. The support cylinder 26 and the limiting column 30 are concentrically arranged. A contact block 28 that abuts against the contact block 28 is slidably installed in the guide column 29 and the limiting column 30. The connected wedge block 31 has a relatively flat contact surface with the two groups of abutment blocks 28 to reduce the friction generated during transmission and increase the service life of components. The wedge block 31 is a Z-shaped structure. A strong spring 32 fixedly connected to the pressing cylinder 27 is fixedly mounted on the limit column 30. The strong spring 32 is a mechanical part that uses elasticity to work. It is made of elastic material and deforms under the action of external force. It returns to its original shape after the external force is removed, making it convenient to reset the limit column 30.

[0026] It should be noted that the specific models and specifications of the first drive motor 9 and the second drive motor 10 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0027] The present invention can be explained by the following operation mode: Move the device to the designated position, turn on the first drive motor 9, control the drive gear 12 to rotate clockwise, drive the driven gear 15 to rotate clockwise through the transmission track 16, thereby pulling and driving the nut 13 to rotate clockwise, and then control the screw rod 14 to move upward, drive the support plate 5 to move upward, at this time, the four sets of slide columns 4 will slide upward synchronously to adjust the height of the air detector 2; Turn on the second drive motor 10 and control the drive turntable 22 to rotate clockwise. When the rotating wheel 21 contacts the plane of the drive turntable 22, the abutment claw 20 will move to the tooth groove of the lower end transmission gear 17 at the position. When the rotating wheel 21 contacts the arc surface of the drive turntable 22, the abutment claw 20 will move the transmission gear 17, thereby driving the support turntable 7 to rotate clockwise, thereby adjusting the direction of the output end of the air detector 2; Before the air is sucked into the air detector 2, the air will be screened by the filter plate 24 to block the existing solid impurities. When the air detector 2 is stopped, the solid impurities fall into the collection frame 25, pressing the pressing cylinder 27 downward, the strong spring 32 is compressed, and the resistance block 28 moves downward, driving the wedge block 31 to slide to the right, thereby guiding the limit column 30 and controlling it to slide into the pressing cylinder 27, releasing the restriction on the position of the collection frame 25, taking the collection frame 25 out of the installation box 23, and taking the filter plate 24 upward to clean the filter plate 24 and the collection frame 25.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
