DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A VOC detection device with a water accumulation reminder structure may include a detection body 10, a water accumulation detector 20 and a drainer 30. The water accumulation detector 20 is installed at the bottom of the detection body 10, and the detection end of the water accumulation detector 20 extends into the inner cavity of the collection cover 31 in the drainer 30, so that it can be used to detect whether there is water accumulation. The drainer 30 is installed at the bottom of the detection body 10 and is used to divert and drain water when there is water accumulation.

[0025] See also Figure 2, the detection body 10 may include an outer shell 11, a VOC detector 12, a filter 13 and a bracket 15. The bracket 15 is welded and fixed to the bottom of the outer shell 11, and supports the outer shell 11 at a certain height. The outer shell 11 is made of a rectangular shell structure by bending, welding and other processes using steel plates, and the surface of the outer shell 11 is sprayed with an anti-rust coating. A fixed display screen is installed on the front of the outer shell 11 to display the detection data, which is convenient for maintenance personnel to inspect and check. The VOC detector 12 and the filter 13 are installed inside the outer shell 11, and the input end of the VOC detector 12 is connected to the filter 13, so that when the VOC detector 12 is used for monitoring and detection, the gas can be pre-filtered through the filter 13 to remove larger particulate impurities and then detected. A positioning groove 14 is provided on the bottom of the outer shell 11, and the positioning groove 14 constitutes a gap at the bottom of the detection body 10 and is used for positioning and installing the drainer 30.

[0026] In this embodiment, the water accumulation detector 20 may include a support frame and a liquid level sensor. The support frame may be bent into an inverted "L" shape and welded to the inner side wall of the outer shell 11. The detection end of the liquid level sensor extends downward into the collection cover 31 and is fixed to the bottom of the support frame by two sets of nuts, so that it can be used to detect whether there is water accumulation.

[0027] See also Figure 3 and Figure 4 The drainer 30 may include a collecting hood 31, a guide cover 32 and an opening and closing mechanism 33. The upper end of the collecting hood 31 is embedded in the notch of the detection body 10 and is welded and fixed to the detection body 10. The shape of the collecting hood 31 can be made into a boss shape, and the bottom opening section of the collecting hood 31 is smaller than the top opening section of the collecting hood 31 for installation and welding, so that when the water flows into the collecting hood 31, it can be guided downward to accumulate. The guide cover 32 is hinged at the lower end of the collecting hood 31 and covers the bottom opening of the collecting hood 31. The opening and closing mechanism 33 is installed on the inner wall of the detection body 10, and the opening and closing mechanism 33 has a movable end that drives and connects the guide cover 32, so that the opening and closing mechanism 33 adjusts the covering state of the guide cover 32 on the collecting hood 31. When the guide cover 32 deflects downward, the water can be discharged from the lower end opening of the collecting hood 31.

[0028] In this embodiment, the guide cover 32 includes a cover plate 321, two sets of lifting ears 322 and an insertion shaft 323. The cover plate 321 is hinged at the lower end of the collection cover 31, and the cross-sectional size of the guide cover 32 is slightly larger than the cross-sectional size of the bottom opening of the collection cover 31, so that the guide cover 32 can cover the opening when it fits the bottom of the collection cover 31. The two sets of lifting ears 322 are fixed to the side ends of the upper surface of the cover plate 321, and the insertion shaft 323 is fixedly connected between the two sets of lifting ears 322, and the insertion shaft 323 is used to connect and cooperate with the movable end of the opening and closing mechanism 33.

[0029] In this embodiment, the opening and closing mechanism 33 includes a mounting frame 331, a hydraulic cylinder 332, and a collar 333. The mounting frame 331 is fixedly mounted on the inner side of the outer shell 11 in the detection body 10, the top pivot of the hydraulic cylinder 332 is connected to the mounting frame 331, and the collar 333 is fixedly connected to the output end of the hydraulic cylinder 332. The collar 333 is sleeved on the outer side of the plug shaft 323, and the collar 333 and the output end of the hydraulic cylinder 332 constitute the movable end of the opening and closing mechanism 33, so that when the output end of the hydraulic cylinder 332 extends downward, the collar 333 can be used to apply force to the plug shaft 323, so that the cover plate 321 is deflected downward; when the output end of the hydraulic cylinder 332 retracts upward, the collar 333 can be used to apply force to the plug shaft 323, so that the cover plate 321 is deflected upward.

[0030] The system of the present invention may also include a control system for receiving feedback signals from the liquid level sensor and controlling the operation of the hydraulic cylinder, VOC detector, etc., so as to monitor and detect VOC gas and automatically discharge accumulated water. It should be understood that the control system has no particular limitation and can be implemented by the control technology in the prior art, which will not be described in detail here.
