Description

Technical Field

[0001] The invention relates to the technical field of water quality monitoring, and in particular to a highly integrated water quality rapid monitoring device. Background Art

[0002] With the development of society, people pay more and more attention to water safety. When monitoring the water quality of rivers, ultraviolet water quality monitors are mainly used to achieve detection. They mainly detect the chemical oxygen demand (COD) in water through the ultraviolet absorption photometer method, and calculate the comprehensive pollution index of water bodies using the Lambert-Beer law, providing data support for the management and protection of water bodies. When conducting detection, the device is placed underwater manually or controlled by an unmanned boat for detection; In actual use, the existing water quality monitoring device is mainly submerged into water for water quality detection and analysis. However, due to the fluidity of river water, the existing device cannot perform sampling and detection separately during monitoring, which leads to the accuracy of the running detection data due to the effect of water flow. Therefore, in view of the above problems, a highly integrated water quality rapid monitoring device is designed to better meet the actual use needs. Summary of the invention

Connected to the sample storage tank, a guide rod is vertically fixed to the lower end of the piston head, one end of the second spring is fixed on the guide rod, the other end of the second spring is fixed on the movable table, one end of a connecting rod is rotatably connected to the guide rod, and the other end of the connecting rod is rotatably connected to the push rod. When the push rod contacts the fixed cover and moves under force, the transmission action of the connecting rod cooperates with the guide rod to slide upward, and the sample after detection in the sample storage tank is completely discharged through the sliding action between the piston head and the sample storage tank. When the push rod is separated from the fixed cover, the second spring causes the guide rod and the piston head to slide downward, so that water enters the sample storage tank to realize the sampling operation.

[0005] Preferably, a protective cover is fixed to the lower end of the ultraviolet water quality monitor, and a detection probe is arranged inside the protective cover, and the detection probe is fixed at the lower end of the ultraviolet water quality monitor, the protective cover contacts with the movable table to achieve a sealing effect, and the inner diameter of the protective cover is equal to the diameter of the sample storage tank, through the action of the protective cover, the movable table, the sample storage tank and the piston head, the water to be monitored is in a sealed space, thereby effectively avoiding the influence of external water flow, and greatly ensuring the accuracy of the detection data.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. During the use of the highly integrated water quality rapid monitoring device, the movable block can be moved by the cooperation between the lifting ring and the movable block, and then the device's own gravity, so that the card slot on the movable block cooperates with the fixed frame to achieve sealing, and then achieves a self-locking effect, avoiding the separation of the lifting ring and the movable block during the use of the device, thereby ensuring the safety of the device; 2.

DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-Figure 6 The present invention provides a technical solution: a highly integrated water quality rapid monitoring device, comprising an ultraviolet water quality monitor 1 and a fixed cover 3, wherein the fixed cover 3 is fixed at the lower end of the ultraviolet water quality monitor 1, a filter screen 301 is installed on the fixed cover 3, a hoisting mechanism 2 is installed at the upper end of the ultraviolet water quality monitor 1, and a sampling mechanism 4 is arranged in the fixed cover 3.

[0019] The hoisting mechanism 2 includes a fixed frame 201, a movable block 202, a vertical rod 203, a first spring 204, a lifting ring 205 and a lifting rope 206. The fixed frame 201 is fixed to the upper end surface of the ultraviolet water quality monitor 1, and the movable block 202 is slidably connected to the inner side of the fixed frame 201, and a slot is provided on the movable block 202; the vertical rod 203 is fixed to the upper end of the movable block 202, and the vertical rod 203 and the fixed frame 201 are slidably connected; one end of the first spring 204 is fixed to the movable block 202, and the other end of the first spring 204 is fixed to the fixed frame 201; the slot on the movable block 202 and the lifting ring 205 are sleeved, and the lifting rope 206 is fixed to the lifting ring 205; When using this highly integrated water quality rapid monitoring device, Figure 1-Figure 6As shown, firstly, the lifting ring 205 is sleeved with the card slot on the movable block 202, and then the whole device is lifted by holding the lifting rope 206. At this time, under the action of the device's own gravity, the movable block 202 is forced to move upward, and the sliding guide effect between the vertical rod 203 and the fixed frame 201 can ensure the stability of the movement of the movable block 202, and the first spring 204 is forced to shrink. At this time, the card slot opening on the movable block 202 is completely blocked by the fixed frame 201, so that the self-locking effect can be achieved, which effectively prevents the lifting ring 205 from separating from the movable block 202 during the use of the device, causing the device to fall off, and ensures the safety of the device (wherein the lifting rope 206 can also be connected to the lifting device on the unmanned ship to achieve the function of deep-water unmanned control and monitoring); The sampling mechanism 4 includes a movable platform 407, a sample storage tank 408 and a through hole 409. The movable platform 407 is provided with two sample storage tanks 408. The movable platform 407 is also provided with through holes 409 evenly. The movable platform 407 is connected to the drainage mechanism 5. The drainage mechanism 5 includes a piston head 501, a guide rod 502, a second spring 503, a connecting rod 504 and a push rod 505. The piston head 501 is slidably connected in the sample storage tank 408. The lower end of the piston head 501 is vertically fixed with a guide rod 502. One end of the second spring 503 is fixed on the guide rod 502. The other end of the second spring 503 is fixed to the movable platform 407. On the top, one end of the connecting rod 504 is rotatably connected to the guide rod 502, and the other end of the connecting rod 504 is rotatably connected to the push rod 505. When the push rod 505 contacts the fixed cover 3 and moves under force, the transmission action of the connecting rod 504 cooperates with the guide rod 502 and the piston head 501 to slide upward, and the sample after detection in the sample storage tank 408 is completely discharged through the sliding action between the piston head 501 and the sample storage tank 408. When the push rod 505 is separated from the fixed cover 3, the second spring 503 makes the guide rod 502 and the piston head 501 slide downward, so that water enters the sample storage tank 408 to realize the sampling operation; A protective cover 101 is fixed at the lower end of the ultraviolet water quality monitor 1, and a detection probe 102 is arranged inside the protective cover 101, and the detection probe 102 is fixed at the lower end of the ultraviolet water quality monitor 1, the protective cover 101 contacts with the movable table 407 to achieve a sealing effect, and the inner diameter of the protective cover 101 is equal to the diameter of the sample storage tank 408; the sampling mechanism 4 also includes a motor 401, a waterproof cover 402, a disc 403, a convex shaft 404, a slide rod 405, a bracket 406 and a slide rod 410, the motor 401 is fixed on the fixed cover 3, and the outer side of the motor 401 is provided with A waterproof cover 402 is provided, and the waterproof cover 402 is fixed on the fixed cover 3; a disc 403 is fixed on the output end of the motor 401, and a convex shaft 404 is fixed on the disc 403, and the convex shaft 404 is slidably connected to the slide rod 405, and the rotation diameter of the convex shaft 404 is equal to the center distance between the two sample storage tanks 408; the slide rod 405 is fixed on the bracket 406, and the bracket 406 is symmetrically fixed to the lower end of the movable platform 407; a sliding rod 410 is also symmetrically fixed on the movable platform 407, and the sliding rod 410 is slidably connected to the fixed cover 3; When testing water quality, Figure 1-Figure 6 As shown, by releasing the suspension rope 206, the entire device sinks into the water. When the device reaches a certain depth, sampling and testing can be carried out. At this time, the external water is filtered through the filter net 301 and enters the fixed cover 3. The filter net 301 can prevent large foreign objects from entering the water, ensuring the normal progress of subsequent testing. At this time, the state of the entire device is as follows: Figure 4As shown, the left piston head 501 is at the uppermost side of the left sample storage tank 408, the left second spring 503 is in a contracted state, and the right sample storage tank 408 cooperates with the protective cover 101. At this time, it is only necessary to start the motor 401 to drive the disc 403 and the convex shaft 404 to rotate 180 degrees, so that the convex shaft 404 moves from the leftmost side to the rightmost side, and the sliding action between the convex shaft 404 and the slide rod 405 makes the bracket 406 and the movable platform 407 move to the right, and the sliding rod 410 and the fixed cover 3 are moved to the right. The sliding guide function can ensure the stability of the movement of the movable platform 407. When the convex shaft 404 moves to the rightmost side, the left sample storage tank 408 cooperates with the protective cover 101, and the right sample storage tank 408 is separated from the protective cover 101. When the movable platform 407 moves to the right, the right push rod 505 is separated from the fixed cover 3. Under the action of the left second spring 503, the left piston head 501 slides downward in the left sample storage tank 408, so that the water sample enters the sample storage tank 408. When the side sample storage tank 408 moves to cooperate with the protective cover 101, the movable platform 407, the piston head 501 and the protective cover 101 form a sealed space, thereby realizing the water sampling function, and then cooperating with the detection probe 102 to realize the water quality detection function, and the water sample seal effectively prevents the water flow from affecting the accuracy of the detection data. After one detection is completed, according to the above principle, the starting motor 401 is controlled to drive the disc 403 and the convex shaft 404 to rotate 180° again. At this time, the movable platform 407 moves to the left. According to the above principle, the right sample storage tank 408 can be sampled for detection. When the left push rod 505 contacts the fixed cover 3 and moves under force, the transmission action of the connecting rod 504 is cooperated to make the left piston head 501 slide upward in the left sample storage tank 408, so that the water sample detected in the left sample storage tank 408 is completely discharged, so that subsequent sampling and detection can be carried out again, avoiding the mixing of the two detected water samples before and after and affecting the accuracy of the detection data. This is the working principle of the highly integrated water quality rapid monitoring device.
