Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically to a water quality testing sampler for ecological parks. Background Technology

[0002] Pet amusement parks are recreational areas that provide pets with a combination of leisure, entertainment, and play. The pools set up in the park are usually an important source of drinking water for pets. However, because pets move around frequently in the park, their hair, dander, saliva, and pollutants such as bacteria and viruses that they may carry can easily enter the pools. Moreover, the environment inside the park is complex, and external dust, impurities, and possible chemical substances can also pollute the pool water quality through various pathways. Therefore, the water quality in the pools of the park needs to be tested regularly.

[0003] When testing water quality, it is usually necessary to use a sampler to take samples from the water body. Most existing samplers use a needle-like structure for the extraction part. By pulling the piston of the needle, the water sample can be drawn into the flexible tube of its extension part to complete the sampling. However, when testing the water quality of an ecological park, it is usually necessary to sample the water at different depths in the pool. However, existing samplers cannot sample the water at different depths in the pool at the same time. Therefore, users need to continuously sample the water at different depths in the pool, which is cumbersome and time-consuming. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing an ecological park water quality testing sampler to solve the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An ecological park water quality testing sampler includes a pole structure and a sampling structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1:

[0032] like Figures 1 to 8 As shown in the figure, this embodiment provides a water quality testing sampler for ecological parks, which mainly consists of a pole structure and a sampling structure.

[0033] In the upright structure, three first connecting rods 1 are vertically distributed and connected to each other through second connecting rods 2. The third connecting rod 3 is connected to the top first connecting rod 1, and the bottom foot 4 is connected to the bottom first connecting rod 1.

[0034] In the sampling structure, a detachable sampling tube 6 is installed on each of the three first connecting rods 1 via a ring buckle 5. The ring buckle 5 consists of two symmetrical semi-rings 51. One end of the two semi-rings 51 is connected by a hinge, and the other end is connected by a buckle 52. One of the semi-rings 51 is fixed to the outside of the first connecting rod 1. When in use, the sampling tube 6 is placed into the ring buckle 5 and the buckle 52 is fastened to complete the installation.

[0035] The sampling tube 6 specifically includes a tube body 61, a first piston 62, an upper tube cap 63, a lower tube cap 64, a one-way valve 65, and a limiting ring 66. Two limiting rings 66 are fixed to the outside of the tube body 61. A ring buckle 5 is sleeved on the tube body 61 and located between the two limiting rings 66, serving to fix and limit the position. The upper tube cap 63 and the lower tube cap 64 are respectively threaded to the top and bottom of the tube body 61. The vent is opened on the upper tube cap 63, and the inlet is opened on the lower tube cap 64. The one-way valve 65 is installed at the inlet to prevent the water sample from flowing back after sampling.

[0036] Each sampling tube 6 in this embodiment can perform sampling operations independently. Since the three first connecting rods 1 are vertically distributed and at different heights, they can be sampled at different depths. The number of first connecting rods 1 can be easily increased or decreased according to usage needs, so that users can increase or decrease the number of sampling tubes 6 according to the actual depth of the ecological garden pool.

[0037] The air pump 7 is fixed to the top of the third connecting rod 3 and includes a cylinder 71, a second piston 72, a pull rod 73 and a handle 74. The air intake is opened on the bottom side of the cylinder 71. The second piston 72 is located inside the cylinder 71. The bottom end of the pull rod 73 is fixed to the top of the second piston 72 and the handle 74 is fixed to the top of the pull rod 73.

[0038] The main pipe 8 has an air outlet and multiple air inlets. The exhaust port of the sampling tube 6 is connected to the air inlet of the main pipe 8 through the branch pipe 9. The suction port of the suction cylinder 7 is connected to the air outlet of the main pipe 8 through the branch pipe 9. The branch pipe 9 is preferably made of flexible hose.

[0039] During sampling, by pulling the handle 74, the pull rod 73 and the second piston 72 move upward in the cylinder 71, creating a negative pressure inside the cylinder 71. Then, through the branch pipe 9 and the main pipe 8, the first piston 62 moves from the bottom to the top of the pipe 61 under the action of negative pressure, creating a negative pressure inside the pipe 61. The water sample enters the pipe 61 through the one-way valve 65, thus completing the sampling.

[0040] Example 2:

[0041] Based on Embodiment 1, in order to achieve precise control of the sampling process, this embodiment installs a shut-off valve 10 on the air inlet of the main pipe 8. When sampling is required at a specific depth of the sampling tube 6, the shut-off valves 10 of other air inlets are closed, and only the shut-off valve 10 corresponding to the target sampling tube 6 is opened. Then, the handle 74 of the suction cylinder 7 is pulled to generate negative pressure in the target sampling tube 6 for sampling. For example, if only water samples at the middle depth need to be sampled, the shut-off valves 10 corresponding to the top and bottom sampling tubes 6 can be closed, and only the shut-off valve 10 corresponding to the middle sampling tube 6 can be opened, thereby ensuring that the water sample accurately enters the target sampling tube 6 and improving the accuracy and flexibility of sampling.

[0042] In addition, it should be noted that the volume of the cylinder 71 of the vacuum cylinder 7 is much larger than the volume of the tubes 61 of the multiple sampling tubes 6, so as to control the multiple sampling tubes 6 to perform sampling operations simultaneously through the vacuum cylinder 7.

[0043] Example 3:

[0044] Based on Embodiment 1, this embodiment optimizes the connection method and structure to facilitate the disassembly, assembly, and carrying of the sampler, with threaded connections between the connecting rods and components.

[0045] In the upright structure, threaded holes are provided at the top of the first connecting rod 1, the top of the second connecting rod 2, and the top of the base 4. Threaded posts are provided at the bottom of the first connecting rod 1, the bottom of the second connecting rod 2, and the bottom of the third connecting rod 3. The assembly of each component is achieved through threaded connection.

[0046] In the sampling structure, both ends of the branch pipe 9 are fixedly connected with internally threaded pipes, and the exhaust port of the sampling pipe 6, the suction port of the suction cylinder 7, and the air inlet and outlet of the main pipe 8 are all fixedly connected with externally threaded pipes, and assembly is achieved through threaded connection.

[0047] During assembly, simply screw the threaded post of the first connecting rod 1 into the threaded hole of the second connecting rod 2 or the base 4 to complete the assembly of the upright structure; similarly, screw the threaded post of the third connecting rod 3 into the threaded hole of the top first connecting rod 1 to complete the top connection. The components of the sampling structure also use threaded connections. The branch pipe 9 is connected to the sampling pipe 6, the vacuum pump 7 and the main pipe 8 through internal and external threaded pipes, which facilitates disassembly and assembly. When carrying, each component can be disassembled and put into a backpack for easy transportation and storage. After arriving at the sampling location, it can be quickly assembled according to the actual use needs, improving work efficiency.

[0048] Working principle and usage process of this utility model:

[0049] When using the water quality testing sampler in this ecological park, it is first necessary to assemble it. Assemble the various components of the upright structure using threaded connections. After the upright structure is assembled, place the sampling tube 6 into the ring buckle 5 and fasten the buckle 52 to fix the sampling tube 6 onto the first connecting rod 1. Repeat this process for all three first connecting rods 1 to complete the installation of the sampling tube 6. Next, connect the air outlet of the main pipe 8 to the air intake of the suction cylinder 7 through the branch pipe 9. Also connect the exhaust port of the sampling tube 6 to the air inlet of the main pipe 8 through the branch pipe 9. Open the shut-off valve 10 on the air inlet of the main pipe 8 connected to the sampling tube 6, and close all other shut-off valves 10. The entire assembly is complete. After completion, the upright structure is erected in the pond of the ecological park, with the base 4 supported at the bottom of the pond. Pull the handle 74 of the air pump 7, which drives the pull rod 73 and the second piston 72 to move upward in the cylinder 71. Through the branch pipe 9 and the main pipe 8, a negative pressure is formed in the three sampling tubes 6, allowing the water sample to enter the sampling tube 6 under the negative pressure, thus completing the sampling operation. After sampling, the sampler is removed from the water, and the sampling tube 6 is removed. If sampling is required, a new sampling tube 6 is installed on the sampler, and the previous sampling operation is repeated. When testing the water sample, the lower tube cap 64 of the sampling tube 6 is opened, and the water sample can be poured out for testing.

[0050] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
