Detailed implementation manners

[0026] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Please refer to Figures 1 to 6 As shown, a chlorine concentration detection device includes a vehicle body 1, a lifting mechanism 2, a detection box 3, a chlorine concentration detector 4, and a filter screen 5. The vehicle body 1 can be an operating trolley in the prior art, including a support plate and rollers fixedly arranged at the four corners of the bottom surface of the support plate to facilitate moving the chlorine concentration detection device to a preset position, which will not be elaborated here. The detection box 3 is arranged above the vehicle body 1. The detection box 3 is a rectangular box with a hollow interior. Ventilation holes 31 and exhaust fans 32 are respectively arranged on two opposite sides of the detection box 3. Among them, there are multiple ventilation holes 31, and the exhaust fan 32 is used to extract external air so that the external air quickly enters the interior of the detection box 3 along the ventilation holes 31.

[0028] The lifting mechanism 2 is fixedly arranged on the top surface of the vehicle body 1. The top end of the lifting mechanism 2 is fixedly connected to the detection box 3. That is, the lifting mechanism 2 is arranged between the detection box 3 and the vehicle body 1 and is used to drive the detection box 3 to move up and down, thereby facilitating the detection box 3 to collect air at different heights. In this embodiment, the lifting mechanism 2 is a telescopic electric cylinder. The chlorine concentration detector 4 is fixedly arranged on the top surface of the detection box 3, and the detection end of the chlorine concentration detector 4 passes through the top surface of the detection box 3 and extends into the interior of the detection box 3 to detect the chlorine concentration of the air inside the detection box 3. Inside the detection box 3, a filter screen 5 is slidably arranged between the chlorine concentration detector 4 and the ventilation hole 31.

[0029] During implementation, the staff moves the vehicle body 1 to a preset position and simultaneously starts the lifting mechanism 2. The lifting mechanism 2 drives the detection box 3 to move to a specified height. At this time, the exhaust fan 32 is started, so that the external air sequentially passes through the ventilation hole 31 and the filter screen 5 and then contacts the detection end of the chlorine concentration detector 4 to detect the chlorine content in the air. By arranging the filter screen 5, large particle dust and impurities in the air are filtered out to avoid affecting the detection accuracy of the chlorine concentration detector 4.

[0030] In this embodiment, a cover plate 6 is arranged on one side of the detection box 3 in the sliding direction of the filter screen 5 and is used to open or close the detection box 3 to facilitate the staff to take out and place the filter screen 5. Please refer to Figure 4 As shown, a spring hinge 61 is arranged on the inner wall of the detection box 3. Two sides of the spring hinge 61 are respectively fixedly connected to the inner wall of the detection box 3 and the inner wall of the cover plate 6. That is, the cover plate 6 is connected to the detection box 3 through the spring hinge 61. It should be noted that the spring hinge 61 is a prior art, and the torsion spring of the spring hinge 61 can realize the function of automatic reset, which will not be elaborated here. Please continue to refer to Figure 5 and Figure 6 As shown, a clamping groove 33 for accommodating the filter screen 5 protrudes from the inner side wall of the detection box 3 far away from the cover plate 6. A push plate 7 is slidably connected to the clamping groove 33. The sliding direction of the push plate 7 is parallel to the sliding direction of the filter screen 5. A compression spring 72 is fixedly arranged on the inner side wall of the detection box 3 far away from the cover plate 6. Two ends of the compression spring 72 are respectively abutted against the inner wall of the detection box 3 and the cover plate 6.

[0031] During installation, the staff pushes one end of the filter 5 against the outer wall of the cover plate 6. When the pressure is greater than the elastic force of the spring hinge 61, the cover plate 6 rotates toward the inside of the box, and then the staff continues to push the filter 5 so that one end of the filter 5 abuts against the push plate 7. At this time, the staff continues to apply thrust to the filter 5. When the thrust is greater than the elastic force of the compression spring 72, the compression spring 72 is compressed, and the push plate 7 moves away from the cover plate 6 until the filter 5 is completely moved into the box and the filter 5 no longer interferes with the cover plate 6. Then the staff stops pushing the filter 5 and moves his hand out of the test box 3. At this time, the cover plate 6 will automatically reset due to the elastic force of the spring hinge 61, sealing the box. At the same time, the elastic force of the compression spring 72 moves the push plate 7 toward the cover plate 6, thereby pushing the filter 5 toward the cover plate 6 until the two ends of the filter 5 abut against the inner walls of the push plate 7 and the cover plate 6, respectively, to complete the installation of the filter 5.

[0032] It should be noted that the sliding distance of the push plate 7 along the card slot 33 is greater than or equal to the width of the cover plate 6, so that the filter 5 can be smoothly pushed into the box body, and at the same time, the two ends of the filter 5 are respectively abutted against the inner walls of the push plate 7 and the cover plate 6 by the reverse push of the push plate 7, so that the filter 5 is firmly fixed in the box body. The cover plate 6, the push plate 7 and the card slot 33 are provided to facilitate the staff to quickly replace the filter 5. Preferably, the spring hinge 61 is provided in two, and the two spring hinges 61 are respectively located at the upper part and the lower part of the cover plate 6, so that the cover plate 6 can rotate more smoothly.

[0033] See also Figure 5 As shown, in this embodiment, two Z-shaped grooves 331 are respectively provided on the two side walls of the card slot 33, and the two Z-shaped grooves 331 are respectively located at the upper part and the lower part of the card slot 33, and a slide bar 71 is fixedly provided on the push plate 7 corresponding to each Z-shaped groove 331, and the slide bar 71 is slidably arranged in the Z-shaped groove 331. During implementation, the staff will place each slide bar 71 at the opening of the Z-shaped groove 331, and then push the push plate 7 to move inside the Z-shaped groove 331 until the slide bar 71 is moved to the lower part of the Z-shaped groove 331, and the slide bar 71 will slide in the lower part of the Z-shaped groove 331. By providing the Z-shaped groove 331, it is convenient to disassemble the push plate 7 while preventing the push plate 7 from accidentally detaching from the Z-shaped groove 331.

[0034] In this embodiment, inside the detection box 3, a partition 8 is fixedly installed between the chlorine gas concentration detector 4 and the exhaust fan 32. A plurality of through holes 81 are formed in the partition 8. The partition 8 divides the interior of the detection box 3 into a detection area 34 and a purification area 35. Above the purification area 35, a spraying assembly 9 is fixedly installed. The spraying assembly 9 includes a plurality of spray heads 95 fixedly installed on the upper part of the purification area 35 and a lye tank 91 fixedly installed on the top surface of the vehicle body 1 for containing lye. The plurality of spray heads 95 are communicated with the lye tank 91 through a pipeline 92 and a chemical pump 93. The bottom surface of the purification area 35 is communicated with a liquid recovery pipe 94. The bottom end of the liquid recovery pipe 94 is communicated with the interior of the lye tank 91.

[0035] During implementation, when the chlorine gas concentration detector 4 detects that the chlorine gas concentration exceeds the standard, the spraying assembly 9 is started. At this time, the chemical pump 93 transports the lye in the lye tank 91 to the spray heads 95 through the pipeline 92 and sprays it into the purification area 35 through the spray heads 95, so that the lye is mixed with the chlorine gas in the air. According to common knowledge, the chlorine gas can be effectively converted into a relatively safe substance through the lye. Therefore, when the chlorine gas concentration is detected to exceed the standard, the chlorine gas in the air can be purified in the first time. It can avoid environmental pollution caused by chlorine gas and even poisoning of the staff. At the same time, the lye in the purification area 35 is recovered into the lye tank 91 through the liquid recovery pipe 94.

[0036] Preferably, the cross-section of the through hole 81 is trapezoidal, and the upper base of the trapezoidal through hole 81 is close to the detection area 34. To prevent the lye from flowing into the detection space along the through hole 81 and damaging the chlorine gas concentration detector 4. Further, a storage battery 10 is fixedly installed on the top of the vehicle body 1. The lifting mechanism 2 and the chemical pump 93 are both electrically connected to the storage battery 10.

[0037] When the utility model is specifically implemented, the staff moves the vehicle body 1 to a preset position, and at the same time starts the lifting mechanism 2. The lifting mechanism 2 drives the detection box 3 to move to a specified height, and then starts the exhaust fan 32. The exhaust fan 32 sucks the external air into the interior of the detection box 3 and filters the large-particle dust and impurities in the air through the filter screen 5. The chlorine gas concentration detector 4 monitors the chlorine gas concentration in the air in real time. When the chlorine gas concentration detector 4 detects that the chlorine gas concentration exceeds the standard, the spraying assembly 9 is started. The chemical pump 93 of the spraying assembly 9 transports the lye in the lye tank 91 to the spray heads 95 through the pipeline 92 and is sprayed into the purification area 35 by the spray heads 95, so that the lye is mixed with the chlorine gas to convert the chlorine gas into a relatively safe substance through the lye, avoiding environmental pollution caused by chlorine gas and even poisoning of the staff.
