[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-4 A rapid water quality testing and sampling device includes a telescopic component 1 and a sealing component 2, with the sealing component 2 installed on top of the telescopic component 1.

[0025] See Figure 2 Furthermore, the telescopic component 1 includes a barrel body 3 and an inner cylinder body 4. The inner cylinder body 4 is movably installed inside the barrel body 3. A handle 5 is connected to the top of the outer side of the inner cylinder body 4. A sealing groove 6 is opened at the top of the inner cylinder body 4. A connecting ring 7 is fixedly installed at the bottom of the outer side of the inner cylinder body 4. A set of screw grooves 8 are opened at the upper and lower ends of the inner wall of the barrel body 3. Sealing rings 9 are provided at the upper and lower ends of the inner side of the barrel body 3.

[0026] The inner diameter of the inner cylinder 4 is smaller than the inner diameter of the barrel 3. The outer diameter of the inner cylinder 4 matches the inner diameter of the top ring of the barrel 3. The inner cylinder 4 is located inside the barrel 3 and is arranged to slide up and down. The sliding of the inner cylinder 4 is used to increase the internal capacity and shorten the overall length.

[0027] The outer ring of the connecting ring 7 is located on the inner wall of the barrel 3 and is slidably positioned, thus restricting the connecting ring 7 to slide within the barrel 3.

[0028] The connecting ring 7 and the two sets of screw grooves 8 are both threadedly connected. The connecting ring 7 and the sealing ring 9 are interlocked. The connecting ring 7 is connected to the screw grooves 8 at the lower or upper end to facilitate the fixing of the inner cylinder 4 after it shrinks or extends.

[0029] Specifically, the inner cylinder 4 slides up and down inside the barrel 3, and the connecting ring 7 is connected and fixed to the screw grooves 8 at the lower and upper ends respectively, so that the barrel 3 can be shortened or lengthened as a whole, so as to facilitate storage and carrying, and to facilitate the sampling of a large amount of water.

[0030] Example 2

[0031] See Figure 3 Furthermore, based on Embodiment 1, the sealing assembly 2 includes a top plate 10, four support columns 11 are fixedly installed between the top plate 10 and the top of the inner cylinder 4, a screw 12 is movably installed through the top of the top plate 10, a knob 13 is fixedly installed at the top of the screw 12, and a sealing plate 14 is fixedly installed at the bottom of the screw 12.

[0032] Four support columns 11 are arranged in a ring between the inner cylinder 4 and the top plate 10. There is a gap between the top plate 10 and the inner cylinder 4, and water enters through the gap between the top plate 10 and the inner cylinder 4.

[0033] The screw 12 passes through the inside of the top plate 10 and is threaded. The sealing plate 14 and the sealing groove 6 are locked together. The screw 12 drives the sealing plate 14 to engage or disengage from the sealing groove 6 through the thread, so as to facilitate the sealing and opening of the inside of the barrel 3.

[0034] Specifically, the screw 12 drives the sealing disc 14 to slide up and down, so that the sealing disc 14 engages and seals with the sealing groove 6 or disengages. Water enters through the gap between the top plate 10 and the inner cylinder 4, and the sealing disc 14 seals the inside of the barrel 3, which facilitates rapid water sampling, convenient sealed storage and transportation, avoids water spillage, and reduces the disassembly and assembly of the cap.

[0035] In actual operation, the rope is connected to the handle 5, and the bucket 3 is placed in the water to take samples for testing.

[0036] When stored and extended, the inner cylinder 4 slides down and retracts into the inside of the barrel 3. Rotating the inner cylinder 4 causes the connecting ring 7 to be threadedly connected to the lower screw groove 8 for fixation, thereby shortening the overall length of the barrel 3 for easy storage and carrying. When used again, rotating the inner cylinder 4 causes the connecting ring 7 to disengage from the lower screw groove 8, and the inner cylinder 4 slides upward and extends. The connecting ring 7 is then connected to the upper screw groove 8 for fixation, thereby increasing the overall capacity inside the barrel 3 for easier water sampling.

[0037] During sampling and sealing, rotating the knob 13 causes the screw 12 to slide upward through the thread, causing the sealing disc 14 to disengage from the sealing groove 6 and opening the top of the inner cylinder 4. The rope is connected to the handle 5, and the barrel 3 is placed in the water body that needs to be tested and sampled. The water enters through the gap between the top plate 10 and the inner cylinder 4. During storage or transportation, the screw 12 drives the sealing disc 14 to engage in the sealing groove 6, sealing the inside of the barrel 3 and preventing water from spilling out, thus reducing the need for disassembly and assembly of the cap.

[0038] By setting the telescopic component 1, the inner cylinder 4 slides inside the barrel 3, which can shorten or extend the length of the barrel 3 for easy storage and carrying, and increase the internal storage capacity during sampling. The connecting ring 7 is threadedly connected to the screw groove 8, so that the inner cylinder 4 can be fixed and sealed after telescopic extension. By setting the sealing component 2, the screw 12 drives the sealing disc 14 to slide up and down, and the water enters through the gap between the top plate 10 and the inner cylinder 4, which facilitates the rapid sampling and sealing of the water, facilitates storage and transportation, reduces the disassembly and assembly of the cap, and facilitates subsequent rapid testing.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
