Specific embodiments
[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0032] Please refer to Figure 1-6 , the present utility model provides a technical solution: a sampling device for water quality detection that prevents blockage, including a water pumping cylinder 1, a sealing disc 2, a water inlet pipe 3, a sampling head 4, a mounting ring 5, a cleaning brush 6, a first gear 7, a second gear 8, a first connecting shaft 9, a protective frame 10, a first micro motor 11, a cover plate 12, an electric telescopic rod 13, a connecting ear 14, a limiting rod 15, a round cover 16, a connecting rope 17, a cross plate 18, a pulley 19, a wire winding disc 20, a second connecting shaft 21, a mounting plate 22 and a second micro motor 23.
[0033] Embodiment 1: When sampling with an existing hand-held sampling device, it is necessary for the staff to approach the water source to manually sample, which reduces safety and is not convenient for adjusting the height for sampling. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 , Figure 2 , Figure 5 and Figure 6, since the connecting rope 17 is connected to the left end of the horizontal plate 18, the connecting rope 17 is overlapped on the upper end of the pulley 19, and the connecting rope 17 is wound on the winding drum 20 with an "I"-shaped cross section. The water pumping cylinder 1 is in a lifting structure on the lower side of the horizontal plate 18 through the winding drum 20 and the connecting rope 17. Therefore, the staff moves the sampler to the bank of the river. When the second micro motor 23 works, it drives the second connecting shaft 21 to rotate on the mounting plate 22, so that the second connecting shaft 21 drives the winding drum 20 to rotate, so that the winding drum 20 releases the connecting rope 17, and the water pumping cylinder 1 drives the connecting rope 17 to descend, so that the connecting rope 17 moves downward inside the left end of the horizontal plate 18, so that the sampling head 4 enters the river, and when the winding drum 20 rotates and reels the connecting rope 17, the connecting rope 17 drives the water pumping cylinder 1 to rise away from the river. The pulley 19 can guide the connecting rope 17 to prevent the connecting rope 17 from being worn, thereby facilitating the height adjustment for sampling;
[0034] Embodiment 2: The existing method of sampling by adjusting the height of the disc through a screw rod, a first circular gear, an internally threaded sleeve, a second circular gear, a motor, etc., but the sampling structure is complicated and inconvenient to repair the sampling structure. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 and Figure 4 , because the outer wall of the cover plate 12 is inlaid with a connecting ear 14 at an equal angle, the diameter of the sealing disc 2 is equal to the inner end diameter of the water pumping cylinder 1, and the limiting rod 15 is nested and connected in the hollow structure of the connecting ear 14, and the upper end of the limiting rod 15 is threadedly connected with a round cover 16. Therefore, before sampling, the electric telescopic rod 13 drives the sealing disc 2 to descend to discharge the gas inside the water pumping cylinder 1. After the sampling head 4 enters the river, the electric telescopic rod 13 is driven to drive the sealing disc 2 to rise, so that water enters the water inlet pipe 3 through the porous structure of the side wall and the bottom of the sampling head 4, and the water sample is allowed to enter the water pumping cylinder 1 through the water inlet pipe 3 for storage. When the electric telescopic rod 13 needs to be repaired, the round cover 16 is rotated to disengage it from the upper end of the limiting rod 15, and the cover plate 12 is pulled upward to separate the connecting ear 14 set at an equal angle from the limiting rod 15, and the electric telescopic rod 13 is taken out from the inside of the water pumping cylinder 1, so as to facilitate the inspection of the sampling structure, and the sampling structure is simple;
[0035] Embodiment 3: In the prior art, water is filtered through a first filter screen and a second filter screen, but the mesh of the filter screen is easily clogged by impurities, resulting in the need to replace the filter assembly and reducing its service life. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 and Figure 3, since the inner wall of the cleaning brush 6 contacts the left wall and the lower end of the sampling head 4, the right end of the first gear 7 is meshed and connected with the second gear 8, and the cleaning brush 6 is rotatably structured outside the sampling head 4 through the second gear 8 and the first gear 7. Therefore, when sampling, the first micro-motor 11 is operated to drive the first connecting shaft 9 to rotate on the protective frame 10. When the first connecting shaft 9 rotates, it drives the second gear 8 to rotate, causing the second gear 8 to mesh with the first gear 7 to drive the mounting ring 5 to rotate on the water inlet pipe 3. When the mounting ring 5 rotates, it drives the cleaning brush 6 to rotate outside the sampling head 4, so that the inner end of the cleaning brush 6 clears the impurities on the side wall and the bottom end of the sampling head 4, preventing the impurities from blocking the porous structure of the sampling head 4, thereby preventing blockage and easily increasing the service life of the filtering component. All the electrical components contained above are prior arts and will not be elaborated here.
[0036] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. Coupled with the circuit connection adopting the conventional connection method in the prior art, they will not be elaborated here.
[0037] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
