DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-6 As shown, this embodiment provides a water quality detection device for water utilization, including a bottom plate 1 and a detection probe 2, wherein:

[0024] A vertical rod 3 is installed on the bottom plate 1, and a horizontal rod 4 is installed on the vertical rod 3. The horizontal rod 4 is installed on the vertical rod 3 by electric slide rails, screw rods and other existing technologies, which can facilitate the detection probe 2 to be immersed in water according to the water level. A vertically arranged lifting rod 5 is installed on the horizontal rod 4, and the detection probe 2 is installed at the bottom end of the lifting rod 5. A lifting structure for driving the lifting rod 5 to rise and fall on the horizontal rod 4 is installed on the horizontal rod 4.

[0025] The lifting structure includes a column tube 7, a motor 8 and a threaded rod 9; the column tube 7 is vertically installed on the cross bar 4, and a telescopic hole is opened at the bottom end of the column tube 7 to slide with the lifting rod 5. The motor 8 is installed at the top end of the column tube 7, one end of the threaded rod 9 is connected to the output shaft of the motor 8, the threaded rod 9 is located in the telescopic hole, and the lifting rod 5 is threadedly mounted on the other end of the threaded rod 9.

[0026] The cross bar 4 is provided with a displacement groove which runs through from top to bottom, and the column tube 7 is slidably installed in the displacement groove.

[0027] It should be noted that the detection probe 2 is an electrode probe, which uses the electrode method to detect water quality. The column tube 7 is slidably installed in the displacement groove through the existing technologies such as electric slide rails and screws. The bottom plate 1 is installed on the concrete column installed in the embankment or reservoir by bolts, and a concrete bridge is set between the concrete column and the embankment to facilitate the staff to reach. When in use, the threaded rod 9 is driven to rotate by the motor 8, and the threaded rod 9 is threadedly matched with the lifting rod 5. The lifting rod 5 cannot rotate in the telescopic hole. The lifting rod 5 can only move up and down. The lifting rod 5 descends to insert the detection probe 2 into the reservoir.

[0028] In actual use, there are two operation modes. One is that the detection probe 2 is immersed in water for a long time, and the water quality can be tested at any time. The other is that the detection probe 2 is suspended for a long time. When the water quality needs to be tested, the motor 8 drives the lifting rod 5 to descend and insert the detection probe 2 into the water for testing.

[0029] A cleaning brush 6 sleeved on a lifting rod 5 is installed on the crossbar 4. When the lifting rod 5 drives the detection probe 2 to move up and down on the crossbar 4, the cleaning brush 6 can sleeve the outer periphery of the detection probe 2 to clean it.

[0030] A mounting structure is provided between the cleaning brush 6 and the column 7, and the cleaning brush 6 is rotatably mounted on the mounting structure. The inner side of the cleaning brush 6 mounting block is connected to a sliding shaft 10, and the outer periphery of the lifting rod 5 is provided with a curved groove 11 that slidably cooperates with the sliding shaft 10.

[0031] The mounting structure includes two positioning blocks 12 and a docking tube 13; the docking tube 13 is connected to the bottom end of the column 7, and the two positioning blocks 12 can be assembled into a cylindrical structure. The inner wall of the positioning block 12 is connected with a snap-in block 14, and the outer side of the docking tube 13 is symmetrically provided with snap-in grooves that are compatible with the snap-in block 14. The cleaning brush 6 is composed of two semi-cylinders, and the bristles are located on the inner side of the semi-cylinder. A semi-circular groove that slides with the semi-cylinder is provided on the inner side of the positioning block 12, and the two positioning blocks 12 are detachably connected by bolts.

[0032] A scraper 15 is installed at the bottom end of the positioning block 12 , and scraper teeth 16 are arranged on the inner circle of the scraper 15 .

[0033] It should be noted that the diameter of the lifting rod 5 is the same as that of the detection probe 2. After the detection probe 2 is finished in the water, or is immersed in the water for a long time, dirt is attached to its surface. When the detection probe 2 is driven to rise by the motor 8, the scraping teeth 16 on the scraper 15 first cut the dirt attached to the outer periphery of the lifting rod 5 and the outer periphery of the detection probe 2 into small pieces of dirt fragments. As the lifting rod 5 is raised, since the lifting rod 5 can only rise straight, the sliding shaft 10 slides in the curved groove 11, so that the cleaning brush 6 reciprocates to wipe off the broken dirt on the outer periphery of the lifting rod 5 and the outer periphery of the detection probe 2, which can ensure the cleanliness of the lifting rod 5 and the detection probe 2.

[0034] The staff can reach the cement column through the cement bridge at regular intervals, first operate the motor 8 to raise the detection probe 2, then drive the column tube 7 to move horizontally to the top of the cement column through the electric slide rail, and then drive the cross bar 4 to descend to a height of 1-1.3m through the screw. The staff will disassemble the two positioning blocks 12 and take out the internal cleaning brush 6 for cleaning or replacement to ensure the cleaning effect, while also ensuring the cleanliness of the surface of the detection probe 2 and the result of the water quality detection. The clamping block 14 is clamped into the clamping groove, which can limit the position of the column positioning block 12, prevent the rotation of the positioning block 12, and ensure the rotation of the cleaning brush 6.

[0035] 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.
