DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figures 1 to 5In this embodiment, a lithium battery diaphragm production workshop environment monitoring device is provided, including a detection box 1, an air inlet cylinder 2 is fixedly connected to the bottom of the detection box 1, and a plurality of external air inlets 3 are opened on the air inlet cylinder 2, and a mounting plate 4 is connected to the top of the detection box 1;

[0024] A partition 11 is fixedly connected inside the detection box 1, a fixed box 12 is provided in the middle of the partition 11, a detection component 14 is installed inside the fixed box 12, detection ports 121 are provided on both sides of the partition 11 on the fixed box 12, and a sealing plate 13 is fixedly connected to the bottom of the detection box 1 above the air inlet cylinder 2, and internal air inlets 131 are provided on the sealing plate 13 on both sides of the partition 11.

[0025] When in use, a one-way valve needs to be provided on the inner air inlet 131 to ensure that gas can only enter the interior of the detection box 1 through the inner air inlet 131. The detection space inside the detection box 1 is divided into two independent detection spaces by the partition 11. The detection spaces on both sides are detected respectively by the detection component 14, thereby improving the accuracy of the data during detection.

[0026] In a further embodiment, an air intake fan is installed inside the air intake cylinder 2, and the gas flows toward the sealing plate 13. When the air intake fan is started, air is drawn in from the external air inlet 3, and the air enters the detection box 1 through the air inlet 131 to wait for detection.

[0027] In further embodiments, see Figures 4-5 The detection assembly 14 includes a rotating table 141, a driving device 146 is connected below the rotating table 141, and the driving device 146 is fixedly installed at the bottom of the fixed box 12. An arc plate 143 is fixedly connected above the rotating table 141, and a top plate 142 is fixedly connected above the arc plate 143. A gas sensor 145 is installed inside the arc plate 143 above the rotating table 141. The rotating table 141 is driven to rotate by the driving device 146, and the rotating table 141 rotates to drive the arc plate 143 and the gas sensor 145 to rotate together. When the arc plate 143 faces the detection port 121 on the fixed box 12, the internal space of the arc plate 143 is connected to the space inside the detection box 1 through the detection port 122, and the gas inside the space can be detected through the gas sensor 145. When the arc plate 143 rotates toward another detection port 121, two samples can be detected, and the two samples are compared through the existing technology, thereby avoiding data with large errors.

[0028] When the arc plate 143 faces the inner wall of the fixed box 12, the spaces on both sides of the detection box 1 are connected through the other side of the arc plate 143, and the gas inside the detection box 1 can be discharged through the internal air outlet 144, and new air is introduced into the air inlet tube 2, so that the detected gas is blown out and replaced with a new sample for detection.

[0029] In further embodiments, see Figure 2 The mounting plate 4 includes a plate body 41, a plurality of foot pads 42 are fixedly connected to the periphery of the plate body 41, and an outgoing air outlet 43 is provided on the plate body 41. The foot pads 42 raise the distance between the plate body 41 and the mounting surface, thereby ensuring that the gas flowing out of the outgoing air outlet 43 can be discharged smoothly.

[0030] In further embodiments, see Figures 2 to 4 An inner air outlet 144 is provided above the top plate 142, and the inner air outlet 144 is located above the outer side of the arc plate 143, and the inner air outlet 144 can overlap with the outer air outlet 43. When the outer air outlet 43 overlaps with the inner air outlet 144, the air inside the detection box 1 can flow out through the inner air outlet 144 and the outer air outlet 43, thereby discharging the detected gas and sucking in new gas through the air inlet 2 for detection.

[0031] In further embodiments, see Figure 4 The gas sensor 145 is a dust sensor. The dust content in the air is monitored by the dust sensor to avoid accidents caused by excessive dust content in the air.

[0032] In further embodiments, see Figure 1 The outer air inlet 3 is provided with a grille structure to prevent insects and other debris from entering the air inlet 2, thereby affecting the monitoring result.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
