DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] A waterproof device for a photosynthesis measuring instrument, such as Figure 1-Figure 8 As shown, it includes a measuring instrument 1, on which a measuring handle 2 is placed, and an observation panel 3 is installed on the front side of the measuring instrument 1. It also includes: a waterproof mechanism 4, which is arranged on the outside of the measuring instrument 1 for waterproof protection; a buffer mechanism 5, which is arranged at the lower part of the waterproof mechanism 4 for overall support and bottom waterproof protection; a locking mechanism 6, which is arranged on the waterproof mechanism 4, and the locking mechanism 6 can lock and limit the waterproof mechanism 4 after the rainfall increases.

[0029] It should be noted that the determination of photosynthesis is an important aspect of plant physiology research. It helps scientists understand how plants use light energy to convert carbon dioxide and water into organic matter. In order to accurately measure the rate of photosynthesis, researchers generally use the measuring instrument 1 for operation assistance. The measuring instrument 1 needs to be used outdoors for a long time. In order to prevent the measuring instrument 1 from being damaged by water, the present device can be used to provide waterproof protection for the measuring instrument 1. The waterproof mechanism 4 is used to shield the measuring instrument 1. At the same time, rainwater is blocked during the use of the measuring handle 2. The buffer mechanism 5 is used to raise the overall height of the device to achieve synchronous waterproof protection of the bottom. When the precipitation is large, the locking mechanism 6 will be affected by the total amount of rainwater to automatically control and lock the waterproof mechanism 4, thereby improving the protection capability of the device under heavy precipitation conditions.

[0030] The waterproof mechanism 4 includes an installation frame 41, and the measuring instrument 1 is placed in the installation frame 41. The left and right parts of the installation frame 41 are rotatably provided with a rotating frame 42. The upper sides of the front and rear parts of the rotating frame 42 are provided with water diversion grooves. The rotating frame 42 is provided with a suction component 44. The upper sides of the left and right parts of the installation frame 41 are provided with a magnetic component 43. The magnetic component 43 and the corresponding suction component 44 can be adsorbed and connected.

[0031] It should be noted that when performing specific measurement operations, the rotating frame 42 is pulled to rotate and unfold to both sides, and finally the suction member 44 on the rotating frame 42 can be adsorbed and connected with the magnetic suction member 43 at the corresponding position to complete the fixation of the rotating frame 42. After that, the measuring handle 2 is placed in the protective range at the bottom of the rotating frame 42 for operation.

[0032] The buffer mechanism 5 includes a protective frame 51, and the protective frames 51 are arranged on the lower sides of the left and right parts of the installation frame 41. Electric push rods 52 are installed inside the protective frames 51. Sliding plates 53 are connected to the telescopic ends of the electric push rods 52. The sliding plates 53 are slidably connected to the adjacent protective frames 51. Elastic parts 54 are arranged on the upper sides of the left and right parts of the sliding plates 53. Two rotating rollers 55 are rotatably connected to the bottom of the sliding plates 53.

[0033] It should be noted that when the device is placed on the ground, in order to prevent the accumulation of water on the ground from affecting the device, the electric push rod 52 can be controlled to move, so that the sliding plate 53 drives the rotating roller 55 to move downward, and finally the sliding plate 53 drives the rotating roller 55 to contact the ground, and rely on the assistance of the electric push rod 52 to lift the entire device to achieve the effect of increasing waterproofness. In this process, the elastic member 54 is relied on to improve the supporting and buffering capacity between the sliding plate 53 and the rotating roller 55.

[0034] It also includes a locking mechanism 6, which includes a floating plate 61. Two floating plates 61 are slidably connected to the inside of the rotating frame 42, and the floating plates 61 are connected with latches 62. Two front-to-back symmetrical fixing members 63 are connected to the left and right sides of the upper part of the installation frame 41, and the latches 62 can be engaged with adjacent fixing members 63. The front and back sides of the installation frame 41 are connected with two left-to-right symmetrical water guide members 64 by bolts, and the water guide members 64 are all Z-shaped structures.

[0035] It should be noted that when precipitation continues to increase, rainwater will flow into the water guide member 64 through the water guide groove on the rotating frame 42. After the water flows into the water guide member 64, it will exert force on the floating plate 61. The floating plate 61 moves upward under the influence of buoyancy, so that the latch 62 is inserted into the corresponding fixing member 63. At this time, the rotating frame 42 is fixed and locked by relying on the cooperation between the latch 62 and the fixing member 63. This can avoid excessive precipitation and the impact of rainwater on the rotating frame 42 causing excessive pressure, causing the rotating frame 42 to accidentally flip over and close, affecting the normal use of the device.

[0036] Example 2

[0037] On the basis of Example 1, a fixing mechanism 7 is also included, and the fixing mechanism 7 includes a plug-in 71. Two left-right symmetrical plug-ins 71 are slidably connected to the bottom of the installation frame 41. Springs 72 are connected between the plug-in 71 and the installation frame 41. A protrusion 73 is installed on the plug-in 71, and the protrusion 73 is slidably connected to the adjacent rotating frame 42.

[0038] It should be noted that when the rotating frame 42 is closed and reset, the rotating frame 42 will squeeze and push the protrusion 73, so that the protrusion 73 moves and rises along the groove on the rotating frame 42, so that the plug-in 71 is no longer inserted into the soil for fixation, and the spring 72 will also be stretched by the force. Then, as the rotating frame 42 is flipped open, the protrusion 73 will start to move downward and reset along the groove of the rotating frame 42, so that under the help of the spring 72, the plug-in 71 will move directly downward, thereby inserting into the soil to reinforce the device.

[0039] The cover mechanism 8 also includes a fixing seat 81 . The fixing seat 81 is connected to the front side of the upper portion of the installation frame 41 . A rotating plate 82 is rotatably connected to the fixing seat 81 . The rotating plate 82 is used to close the installation frame 41 .

[0040] It should be noted that, under normal circumstances, the rotating plate 82 and the fixing seat 81 cooperate to seal and protect the installation frame 41 to prevent the measuring instrument 1 from being accidentally damaged under normal conditions.

[0041] The measuring instrument 1 further comprises a limiting mechanism 9 , which comprises a fixing frame 91 . The fixing frame 91 is arranged on the top of the measuring instrument 1 , and a pressing piece 92 for limiting the measuring handle 2 is installed on the fixing frame 91 .

[0042] The above description is only an example of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention should be included in the protection scope of the present invention. The contents not elaborated in detail in the present invention belong to the existing technologies known to those skilled in the art.
