Description

Technical Field

[0001] This utility model relates to the field of hospital wastewater sampling and testing technology, and in particular to a hospital wastewater testing sampler. Background Technology

[0002] A search revealed CN108896348B, entitled "Sampling Device for Medical Wastewater in a Wastewater Pool." This application describes a sampling method where a water sample bottle with a weight attached is tied to a rope, and a stopper with an additional rope attached is sealed. The sample bottle sinks to a predetermined depth, and the stopper is removed by pulling the rope. However, this sampling method cannot be closed completely, and substances from other water layers can easily mix in during the process of retrieving the sample, leading to inaccurate test results.

[0003] The existing patent technology CN220542536U hospital wastewater testing sampler describes a device including a suction tube and a sampling tube. When sampling hospital wastewater, the sampling tube is inserted into the wastewater. Once the sampling depth is reached, the handle is turned, pulling the first piston to move. This reduces the air pressure between the first and second pistons, causing the second piston to move upwards. Wastewater at this depth, under pressure, passes through a one-way valve and enters the sampling tube, thus completing the sampling. After sampling, the one-way valve closes regardless of pressure, preventing wastewater from different depths from entering the sampling tube and thus avoiding contamination of the water sample. Furthermore, this device is easy to operate; simply turning the handle is sufficient for the operator. The device also features a hollow structure between the first and second pistons, relying on air pressure for operation, resulting in a simpler structure and easier use.

[0004] However, the existing equipment has an integrated structure, which cannot reduce the size of the sampler when it is carried, making it less portable and inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a hospital wastewater testing sampler, which solves the problem that existing equipment has an integrated structure, which cannot reduce the volume occupied by the sampler when carried, making it less portable and inconvenient to use.

[0006] To achieve the above objectives, this utility model provides a hospital wastewater testing sampler, including a sampling cylinder, a water suction device, and a driving assembly. The water suction device is installed inside the sampling cylinder. The driving assembly includes a first connecting cylinder, a driving cylinder, a driving component, a piston, and an extension component. The first connecting cylinder is rotatably connected to the sampling cylinder and is located above the sampling cylinder. The driving cylinder is rotatably connected to the first connecting cylinder and is located on the side of the first connecting cylinder away from the sampling cylinder. The piston is slidably connected to the driving cylinder and is located on the side of the driving cylinder close to the first connecting cylinder. The driving component is installed on the driving cylinder and drives the piston to move. The extension component is installed on the driving cylinder and supports the driving cylinder.

[0007] The driving component includes a mounting base, an electric push rod, and an energy element. The mounting base is fixedly connected to the driving cylinder and is located on the side of the driving cylinder away from the first connecting cylinder. The electric push rod is fixedly connected to the mounting base and is located on the side of the mounting base closer to the piston, and is connected to the piston. The energy element is mounted on the mounting base and provides energy to the electric push rod.

[0008] The energy element includes a power source and a wire. The power source is fixedly connected to the mounting base and is located on the side of the mounting base away from the electric push rod. The wire is fixedly connected to the power source and is located at the output end of the power source, and is connected to the electric push rod.

[0009] The extension member includes a second connecting cylinder and an extension rod. The second connecting cylinder is rotatably connected to the driving cylinder and is located on the side of the driving cylinder away from the first connecting cylinder. The extension rod is rotatably connected to the second connecting cylinder and is located at the end of the second connecting cylinder away from the driving cylinder.

[0010] The extension member further includes a handle, which is fixedly connected to the extension rod and located on the side of the extension rod away from the second connecting cylinder.

[0011] This utility model discloses a hospital wastewater sampling device. A first connecting cylinder is threadedly mounted above a sampling cylinder. The outer side of the sampling cylinder has a thread that mates with the first connecting cylinder, allowing the first connecting cylinder to be rotatably mounted on the sampling cylinder. A driving cylinder is threadedly mounted inside the first connecting cylinder, with its outer side also having a thread that mates with the first connecting cylinder, ensuring stable mounting on the first connecting cylinder. The first connecting cylinder connects the driving cylinder and the sampling cylinder. A piston is slidably mounted on the driving cylinder, allowing it to slide within the cylinder. A driving component is mounted inside the driving cylinder, driving the piston to move, thereby activating the suction device and drawing wastewater into the sampling cylinder. An extension component is mounted on the driving cylinder, extending the length of the sampling device, allowing the sampling cylinder to reach a specified depth for sampling. This reduces the sampler's length for portability, making it easier to carry and improving its portability. Attached Figure Description

[0020] This utility model provides a hospital wastewater testing sampler, including a sampling cylinder 101, a water absorption device (not shown in the figure), and a driving assembly. The driving assembly includes a first connecting cylinder 102, a driving cylinder 103, a driving component, a piston 104, and an extension component.

This solution solves the problem that existing devices have an integrated structure, which cannot reduce the volume occupied by the sampler when carried, resulting in low portability and inconvenience in use.

[0021] In this specific embodiment, the water absorption device is installed inside the sampling cylinder 101. The water absorption device is the sampling structure described in the existing patent technology CN220542536U hospital wastewater detection sampler. The wastewater is drawn into the sampling cylinder 101 by the water absorption device. This solution reduces the length of the sampler when carrying it, making the sampler more convenient to carry and improving its portability.

[0022] The first connecting cylinder 102 is rotatably connected to the sampling cylinder 101 and is located above the sampling cylinder 101. The driving cylinder 103 is rotatably connected to the first connecting cylinder 102 and is located on the side of the first connecting cylinder 102 away from the sampling cylinder 101. The piston 104 is slidably connected to the driving cylinder 103 and is located on the side of the driving cylinder 104 close to the first connecting cylinder 102. The driving component is mounted on the driving cylinder 103 and drives the piston 104 to move. The extension component is mounted on the driving cylinder 103 and supports the driving cylinder 103. The first connecting cylinder 102 is mounted above the sampling cylinder 101 via a threaded structure. The outer side of the sampling cylinder 101 has a thread that mates with the first connecting cylinder 102, so that the first connecting cylinder 102 can be rotatably mounted on the sampling cylinder 101. The driving cylinder 103 is mounted on the first connecting cylinder 102 via a threaded structure. The inner side of the connecting cylinder 102 and the outer side of the driving cylinder 103 have threads that mate with the first connecting cylinder 102, so that the driving cylinder 103 can be stably installed on the first connecting cylinder 102. The first connecting cylinder 102 connects the driving cylinder 103 and the sampling cylinder 101. The piston 104 is slidably installed on the driving cylinder 103, so that the piston 104 can slide in the driving cylinder 103. The driving member is installed on the inner side of the driving cylinder 103, and drives the piston 104 to move through the driving member, thereby driving the water suction device to operate, and then drawing wastewater into the sampling cylinder 101. The extension member is installed on the driving cylinder 103, and increases the length of the sampling device through the extension member, so that the sampling cylinder 101 can extend to a specified depth for sampling, thereby reducing the length of the sampler when carrying it, making the sampler more convenient to carry and improving the portability of the sampler.

[0023] Secondly, the mounting base 105 is fixedly connected to the drive cylinder 103 and is located on the side of the drive cylinder 103 away from the first connecting cylinder 102; the electric push rod 106 is fixedly connected to the mounting base 105 and is located on the side of the mounting base 105 close to the piston 104, and is connected to the piston 104; the energy element is installed on the mounting base 105, and the energy element provides energy to the electric push rod 106. The mounting base 105 is installed on the inner side of the drive cylinder 103 by bolts, and the electric push rod 106 is installed on the side of the mounting base 105 close to the piston 104 by bolts, and the output end of the electric push rod 106 is connected to the piston 104 by bolts. The electric push rod 106 drives the piston 104 to move, thereby making the water suction device operate. The energy element is installed on the mounting base 105 and provides power to the electric push rod 106, enabling the electric push rod 106 to operate normally.

[0024] Meanwhile, the power supply 107 is fixedly connected to the mounting base 105 and located on the side of the mounting base 105 away from the electric push rod 106; the wire 108 is fixedly connected to the power supply 107 and located at the output end of the power supply 107, and connected to the electric push rod 106. The power supply 107 is installed on the side of the mounting base 105 away from the electric push rod 106 by bolts. The wire 108 is installed on the power supply 107, and the other end of the wire 108 is installed on the electric push rod 106. The power of the power supply 107 is transmitted to the electric push rod 106 through the wire 108, thereby enabling the electric push rod 106 to operate normally.

[0025] Additionally, the second connecting cylinder 109 is rotatably connected to the driving cylinder 103 and is located on the side of the driving cylinder 103 away from the first connecting cylinder 102; the extension rod 110 is rotatably connected to the second connecting cylinder 109 and is located at the end of the second connecting cylinder 109 away from the driving cylinder 103. The second connecting cylinder 109 is installed on the end of the driving cylinder 103 away from the first connecting cylinder 102 via a threaded structure. The extension rod 110 is a shortenable short rod and is installed on the side of the second connecting cylinder 109 away from the driving cylinder 103 via a threaded structure. The second connecting cylinder 109 enables the extension rod 110 to be stably installed on the driving cylinder 103, thereby enabling the extension rod 110 to support the driving cylinder 103 and allowing the sampling to extend to a specified depth for sampling.

[0026] Finally, the handle 111 is fixedly connected to the extension rod 110 and is located on the side of the extension rod 110 away from the second connecting cylinder 109. The handle 111 is bolted to the end of the extension rod 110 away from the second connecting cylinder 109. The handle 111 allows the operator to hold the extension rod 110 more comfortably, thereby improving the comfort during use.

[0027] Using a hospital wastewater testing sampler according to this embodiment, in use, the first connecting cylinder 102 is first installed above the sampling cylinder 101 by rotation. Then, the driving cylinder 103 is installed on the first connecting cylinder 102 by rotation, so that the driving cylinder 103 is stably installed on the first connecting cylinder 102. The extension rod 110 is installed on the driving cylinder 103 through the second connecting cylinder 109, so that the sampling cylinder 101 can reach a specified depth. When the sampling cylinder 101 reaches the specified depth, the electric push rod 106 is activated. The electric push rod 106 drives the piston 104 to move upward, thereby causing the water suction device to suck the wastewater into the sampling cylinder 101, thus completing the sampling. After the sampling is completed, the extension rod 110 and the driving cylinder 103 are removed in sequence, thereby reducing the length of the sampler when carrying it, making the sampler more convenient to carry and improving the portability of the sampler.
