DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 8 As shown, the present invention provides a portable environment monitoring system, including a first bracket mechanism 1 composed of a first vertical bracket 101, a first connecting rod 102 and a movable wheel 103, the first vertical bracket 101 is symmetrically and fixedly installed at both ends of the first connecting rod 102, and the movable wheel 103 is rotatably connected to both sides of the first connecting rod 102, and also includes, A second bracket mechanism 2, the second bracket mechanism 2 is arranged on the surface of the first vertical bracket 101; A data acquisition mechanism 3, which is arranged on the inner side of the second bracket mechanism 2; A first supporting mechanism 4, which is disposed on a surface of the first connecting rod 102; A limiting mechanism 5, which is arranged on the inner side of the second bracket mechanism 2; The second supporting mechanism 6 and the limiting mechanism 5 are arranged on the surface of the first connecting rod 102; Among them, the first supporting mechanism 4 includes a first connecting plate 401, a second connecting plate 402, a first clamping block 403, a connecting assembly 404, a top support assembly 405 and a third spring 406. The first connecting plate 401 is symmetrically and movably connected to the surface of the first connecting rod 102, the second connecting plate 402 is movably connected to the opposite side of the two first connecting plates 401, the first clamping block 403 is fixedly installed on the first connecting plate 401 and the first clamping block 403 is coaxial with the first connecting rod 102, the connecting assembly 404 is rotatably connected to the surface of the first clamping block 403, and the top support assembly 405 is rotatably connected to the connecting assembly 404.

[0022] The above scheme is adopted: the first bracket mechanism 1 and the second bracket mechanism 2 are arranged to cooperate to be retractable, so that the overall length can be adjusted, which is convenient for carrying; by rotating the first connecting plate 401, the first clamping block 403 can be driven to rotate; with the cooperation of the second bracket mechanism 2, the second supporting mechanism 6 and the limiting mechanism 5, the data acquisition mechanism 3 can be conveniently adjusted in height, which is convenient for installation.

[0023] like Figure 5 , 6As shown, the connecting assembly 404 includes a third connecting rod 4041 and a telescopic sleeve 4042, the third connecting rod 4041 is hinged to the first clamping block 403, the telescopic sleeve 4042 is fixedly installed on one end of the third connecting rod 4041 away from the first clamping block 403, the top support assembly 405 includes a top support rod 4051 and a limit block 4052, the top support rod 4051 is rotatably connected to the telescopic sleeve 4042, the limit block 4052 is fixed to the side of the first vertical bracket 101 and the limit block 4052 is slidably connected to the top support rod 4051.

[0024] By adopting the above scheme: the rotation of the first clamping block 403 can drive the top support rod 4051 to move upward through the third connecting rod 4041 and the telescopic sleeve 4042, and the upward movement of the top support rod 4051 can push the first movable clamping block 502 to move, thereby canceling the locking of the data acquisition chamber 301 by the first movable clamping block 502. At this time, under the action of the first spring 2033, the data acquisition chamber 301 moves upward. In this way, the height of the data acquisition chamber 301 can be increased, which is convenient for the operator to install the detection unit 302.

[0025] like Figure 2 , 4 As shown, the second bracket mechanism 2 includes a second vertical bracket 201, a second connecting rod 202, a first elastic component 203 and a second spring 204. The second vertical bracket 201 is movably connected to the surface of the first vertical bracket 101. The second connecting rod 202 connects two symmetrically arranged second vertical brackets 201. The first elastic component 203 is fixedly installed at both ends of the second connecting rod 202. The data acquisition mechanism 3 includes a data acquisition chamber 301 and a detection unit 302. The data acquisition chamber 301 is slidably connected to the surface of the second vertical bracket 201. The detection unit 302 is movably connected to the surface of the second vertical bracket 201. It is dynamically installed on the side of the data acquisition chamber 301, and the first elastic component 203 includes a connecting chamber 2031, a bellows 2032 and a first spring 2033. The connecting chamber 2031 is fixedly connected to the second connecting rod 202, and the two ends of the bellows 2032 are respectively fixedly connected to the connecting chamber 2031 and the data acquisition chamber 301. The first spring 2033 is sleeved on the surface of the bellows 2032 and its two ends are respectively fixedly connected to the connecting chamber 2031 and the data acquisition chamber 301. An exhaust hole connected to the inside of the bellows 2032 is opened on the connecting chamber 2031.

[0026] The above scheme is adopted: the data acquisition mechanism 3 can be moved upward by the pulling force of the first spring 2033, and the arranged bellows 2032 can discharge the internal gas through the exhaust hole on the connecting chamber 2031 when the data acquisition mechanism 3 moves upward. The aperture of the exhaust hole can reduce the speed of the data acquisition mechanism 3 moving upward, thereby achieving a buffering effect, preventing the data acquisition chamber 301 from moving upward quickly under the pulling force of the first spring 2033 and causing damage due to collision. A plurality of detection units 302 are arranged, each detection unit 302 monitors one data, and the data acquisition chamber 301 is installed with a sensor corresponding to the detection.

[0027] like Figure 2 , 3 As shown, the limiting mechanism 5 includes a fourth connecting rod 501, a first movable block 502 and a fourth spring 503. The fourth connecting rod 501 connects the two second vertical brackets 201. The first movable block 502 is slidably connected inside the fourth connecting rod 501. The first movable block 502 can move inside the fourth connecting rod 501 along the axial direction of the fourth connecting rod 501. The two ends of the fourth spring 503 are respectively fixedly connected to the fourth connecting rod 501 and the first movable block 502. The upper and lower ends of the first movable block 502 are both inclined surfaces. The bottom of the data acquisition chamber 301 is provided with a first bayonet adapted to the first movable block 502.

[0028] By adopting the above scheme: the first movable block 502 is set under the elastic force of the fourth spring 503, the downward-moving data acquisition bin 301 can be fixed, so that the data acquisition bin 301 is located in the middle of the second vertical bracket 201 in the storage state, which is more conducive to the protection of the data acquisition bin 301; and the operator can hold the second connecting rod 202 and make the movable wheel 103 roll smoothly to facilitate the movement of the entire device.

[0029] like Figure 3 , 5 As shown, the top end of the top support rod 4051 is arranged on an inclined surface adapted to the bottom of the first movable block 502 , and when the top support rod 4051 moves upward, it can push the first movable block 502 to move axially along the fourth connecting rod 501 .

[0030] The above scheme is adopted: by rotating the first connecting plate 401 during the installation process, the first card block 403 is rotated synchronously, and the top support rod 4051 is driven to move upward through the third connecting rod 4041 and the telescopic sleeve 4042, so that the first movable card block 502 is squeezed by the top support rod 4051, so that the first movable card block 502 is disengaged from the lock on the data acquisition chamber 301. At this time, the data acquisition chamber 301 moves upward under the pulling force of the first spring 2033, which facilitates the use of the device.

[0031] like Figure 7As shown, the second supporting mechanism 6 includes a supporting assembly 601, a second clamping block 602, a movable block 603, a movable plate 604 and a limiting assembly 605. The supporting assembly 601 is rotatably connected to the surface of the first connecting rod 102. The second clamping block 602 is fixedly connected to the side of the supporting assembly 601 and is coaxial with the first connecting rod 102. The movable block 603 is arranged on the side of the supporting assembly 601. The movable block 603 is hinged to the movable plate 604. The movable plate 604 is slidably connected to the surface of the first vertical bracket 101. The limiting assembly 605 is slidably connected to the inside of the first vertical bracket 101. The second clamping block 602 is adapted to fit with the first clamping block 403. The limiting assembly 605 is slidably connected to the movable plate 604.

[0032] By adopting the above scheme: by rotating the support assembly 601, the movable plate 604 can be pushed upward by the movable block 603 connected to the support assembly 601. The upward movement of the movable plate 604 can drive the limiting assembly 605 to cancel the fixation of the second vertical bracket 201, thereby facilitating the increase of the overall length of the device and making installation more convenient.

[0033] like Figure 7 As shown, the support assembly 601 includes a support plate 6011 and a connecting block 6012, the connecting block 6012 is rotatably connected to the first connecting rod 102, the support plate 6011 is fixedly installed at the bottom of the connecting block 6012, the limiting assembly 605 includes a second movable block 6051 and a fifth spring 6052, the second movable block 6051 is slidably connected to the first vertical bracket 101, the fifth spring 6052 is connected to the middle part of two symmetrically distributed second movable blocks 6051, the movable block 603 is hinged on the connecting block 6012, and the second movable block 6051 is slidably connected to the movable plate 604.

[0034] The above scheme is adopted: the fifth spring 6052 applies elastic force to the two second movable blocks 6051 to ensure that the two second movable blocks 6051 are in pressure contact with the inner wall of the first vertical bracket 101. At the same time, when receiving external pressure, the two second movable blocks 6051 can also overcome the elastic force of the fifth spring 6052 and move toward each other, thereby contacting the limit of the second vertical bracket 201.

[0035] like Figure 7 As shown, one end of the second movable block 6051 protrudes from the first vertical bracket 101, and the lower end of the second vertical bracket 201 is provided with a second latch adapted to the end of the second movable block 6051 protruding from the first vertical bracket 101, and the movable plate 604 is slidably connected to the second movable block 6051 through a sliding groove obliquely arranged on the surface.

[0036] The above scheme is adopted: the sliding groove obliquely arranged on the surface of the movable plate 604 can squeeze the two symmetrically distributed second movable blocks 6051 to move toward each other when the movable plate 604 moves upward, so that the second movable blocks 6051 are disengaged from the second bayonet, and then the limitation on the second vertical bracket 201 is cancelled. In this way, when the support assembly 601 is flipped, the second vertical bracket 201 and the surface of the first vertical bracket 101 can be simultaneously moved up, which facilitates the installation of the device.

[0037] like Figure 5 , 8 As shown, the rotation angles of the connecting block 6012, the first connecting plate 401 and the first connecting rod 102 are all ninety degrees.

[0038] By adopting the above scheme: by setting a ninety-degree rotation angle, it can be ensured that after the connecting block 6012 and the first connecting plate 401 are rotated ninety degrees, the two are located on the same horizontal plane, thereby supporting the first bracket mechanism 1 and the second bracket mechanism 2, and by the engagement of the second clamping block 602 with the first clamping block 403, the connecting block 6012 and the first connecting plate 401 are fixed to ensure the stability of the structure.

[0039] The working principle and use process of the present invention: Initial state Figure 8 As shown, when using the device, first flip the first connecting plate 401 to drive the first clamping block 403 to rotate. During the rotation of the first clamping block 403, the top support rod 4051 can be driven to move upward through the connecting assembly 404. The top support rod 4051 moves upward to squeeze the first movable clamping block 502 to move. At this time, the first movable clamping block 502 does not fix the data acquisition chamber 301. The data acquisition chamber 301 moves upward to the upper end of the second vertical bracket 201 under the pulling force of the first spring 2033. Then, the data acquisition chamber 301 and the second vertical bracket 201 can be fixed using plum bolts. Install the detection unit 302 and the data collection chamber 301; After the installation is completed, the first connecting plate 401 is brought into contact with the ground to form a preliminary support for the first vertical bracket 101, the second vertical bracket 201 and other structures, and then the support assembly 601 is flipped over. When the support assembly 601 rotates, the movable block 603 connected to the connecting block 6012 can push the movable plate 604 upward. The movable plate 604 can move upward by squeezing the two symmetrically distributed second movable blocks 6051 to move toward each other through the sliding grooves obliquely arranged on the surface, so that the second movable blocks 6051 are disengaged from the second bayonet, thereby canceling the limit on the second vertical bracket 201. At this time, under the elastic force of the second spring 204, the second vertical bracket 201 moves up along the surface of the first vertical bracket 101, thereby facilitating the increase of the overall length of the device; During transportation, since the detection unit 302 has a regular shape and the sensors are protected by the data collection chamber 301, it is not easily damaged. The movable wheels 103 can be conveniently pulled directly on flat ground, and two people can carry it in the wild with uneven roads.
