Description

Technical Field

[0001] This utility model relates to the technical field of water sample testing equipment, and in particular to a water inlet and outlet device with self-draining and sealing for a water quality sampler. Background Technology

[0002] In the field of water quality testing, water samples are typically pumped from the water area to be tested into sample bottles for storage. When data validity verification is required, the water sample in the sample bottle is removed for testing; otherwise, the sample bottle is emptied after one cycle. Currently, water samplers on the market do not have automatic emptying and automatic sealing functions, or have complex emptying structures, occupy a large space, and have poor sealing effects. Therefore, there is an urgent need for a sample retention, emptying, and sealing device with a simple structure and emptying function. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution:

[0004] This invention provides a self-draining and sealing inlet / outlet device for a water sampler, comprising a sample bottle, a lifting mechanism, and a hoisting mechanism. The lifting mechanism is configured to be inserted into the sample bottle by the hoisting mechanism for inlet / outlet and / or venting operations. When the lifting mechanism is used for venting, it is not connected to anything. This solution uses a single lifting mechanism for inlet / outlet operations. The switching between inlet and outlet functions is controlled by a pump and valve flow path within the device. This pump and valve flow path control method can be implemented using existing technology. Because the sample bottle remains sealed throughout the process, water contamination is avoided.

[0005] Furthermore, the sample bottle includes a bottle body and a bottle mouth. The bottle body is provided with an exhaust port and a first inlet / outlet. The first inlet / outlet is threadedly connected to the bottle mouth. A sealing device is provided inside the bottle mouth, and the sealing device is sealed to the bottle mouth. A waterproof and breathable valve is provided inside the exhaust port to ensure that gas can freely enter and exit the sample bottle, while the water inside the sample bottle will not overflow.

[0006] Furthermore, both the exhaust port and the first inlet / outlet are located on the top of the sample bottle, or the exhaust port is located on the top of the sample bottle, and the first inlet / outlet is located on the bottom of the sample bottle.

[0007] Furthermore, the sealing device includes a seal and a spring, the seal being used to seal the bottle mouth, and the spring being configured to provide a restoring force to the seal.

[0008] Furthermore, the sealing element includes a sealing rod and a first sealing ring. The first sealing ring is disposed at one end of the bottle mouth. The sealing rod includes a sealing rod body, a first protruding end, and a second protruding end, which are respectively located at both ends of the sealing rod body. The second protruding end has a sealing groove for placing the first sealing ring. The spring is sleeved on the sealing rod body and also has one end connected to the sealing rod body. The sealing rod is configured to move away from the bottle mouth under external force and return to its original position under the action of the spring. Under the action of the spring force, the sealing rod and the first sealing ring will seal the first inlet and outlet of the sample bottle, putting it in a closed state.

[0009] Furthermore, the lifting mechanism includes a boss, a second sealing ring, and a sealing ring pressure plate, wherein the second sealing ring and the sealing ring pressure plate are sequentially fixedly arranged on the boss;

[0010] The boss has a placement space for the first protruding end, and a protrusion is provided in the placement space. The protrusion has at least one through hole, and the boss also has a second inlet / outlet, which is connected to the through hole. Specifically, the second inlet / outlet is connected to a water pipe. Under the action of the lifting mechanism, the lifting mechanism moves towards the first inlet / outlet of the sample bottle, the boss lifts the sealing rod away from the bottle mouth, the sample bottle is released from its sealed state, and the inlet / outlet operation is performed. At this time, the second sealing ring fits and seals with the outer ring of the bottle mouth, ensuring the seal of the outer ring of the bottle mouth.

[0011] Furthermore, the lifting mechanism includes a lifting rod and a third sealing ring. The lifting rod has a water inlet for connecting to a water pipe to perform inlet and outlet operations into the sample bottle. The lifting rod is configured to press against the sealing rod away from the bottle mouth; the third sealing ring is configured to fit and seal against the outer ring of the bottle mouth when the lifting rod presses against the sealing rod away from the bottle mouth.

[0012] Preferably, the lifting mechanism includes an electric push rod or a guide rail slide, which controls the height of movement to ensure that the sample bottle is not lifted when the structure is raised.

[0013] Furthermore, the inlet and outlet device also includes a tray, which has placement holes for placing the first inlet and outlet.

[0014] Preferably, the sample bottles are placed in a ring around each other within the tray. The cross-section of each sample bottle is triangular. By placing the sample bottles in a ring around each other within the tray, more sample bottles can be placed in the same space, which reduces the space required for placing the sample bottles and also reduces the overall volume of the water sampler.

[0015] Furthermore, the inlet and outlet drainage device also includes a rotary motor, which drives the tray to rotate and move the target sample bottle to the lifting mechanism. When a sample bottle needs to be inlet or outlet, the rotary motor can be controlled to rotate and move the target sample bottle to the lifting mechanism. The lifting mechanism then lifts the sealing rod with the protrusion under the action of the lifting mechanism to perform the inlet and outlet drainage operation.

[0016] Preferably, to facilitate smoother tray rotation, a sliding device can be provided at the bottom of the tray to assist in its rotation.

[0017] Furthermore, the inlet and outlet drainage device also includes an identification device or a positioning device for identifying or locating the target sample bottle. The identification device includes, but is not limited to, limit switches and magnetic encoders.

[0018] This utility model has the following beneficial effects:

[0019] (1) In this utility model, the inlet and outlet of the sample bottle are connected to the same port. The lifting mechanism is connected to the inlet and outlet pipe. When the lifting mechanism is pushed into the sealing device, the second sealing ring or the third sealing ring is sealed with the outer ring of the bottle mouth. The sample bottle is still isolated from the external environment, thus avoiding the risk of water quality being polluted during the inlet and outlet process.

[0020] (2) In this utility model, the inlet and outlet of the sample bottle are moved towards the first inlet and outlet of the sample bottle under the action of the lifting mechanism. The boss or the top rod lifts the sealing rod away from the bottle mouth, releases the sealing state of the sample bottle, and performs the inlet and outlet operation. After the operation is completed, the lifting mechanism moves away from the sample bottle under the action of the lifting mechanism, and the sealing rod seals the sample bottle, thus realizing automatic emptying and automatic sealing.

[0021] (3) The present invention achieves the function of water inlet and drainage by means of the cooperation of the sample bottle with sealing device, the lifting mechanism and the lifting mechanism, without the need for a long stroke telescopic rod, so that the entire water inlet and drainage device occupies little space;

[0022] (4) This utility model has a simple structure and low cost. Attached Figure Description

[0029] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. It should be noted that the embodiments are only specific descriptions of the utility model and should not be regarded as limitations on the utility model. The purpose of the embodiments is to enable those skilled in the art to better understand and reproduce the technical solution of this utility model. The protection scope of this utility model should still be determined by the scope defined in the claims. Example

[0030] like Figure 1 As shown, this embodiment provides a self-draining and sealing inlet / outlet device for a water quality sampler, including a sample bottle 1, a lifting mechanism 2, and a lifting mechanism 3. The lifting mechanism 2 is configured to be pushed into the sample bottle 1 by the lifting mechanism 3 to perform inlet / outlet operations. The lifting mechanism 2 is connected to a water pipe, and the pump and valve flow path within the device controls the movement of the lifting mechanism into the sample bottle 1 under the action of the lifting mechanism 3 to perform inlet / outlet operations. Because the sample bottle remains sealed throughout the process, water contamination is avoided.

[0031] like Figure 2 As shown, the sample bottle 1 includes a bottle body 11 and a bottle mouth 12. The bottle body 11 is provided with an exhaust port 111 and a first inlet / outlet 112. The exhaust port is located at the top of the sample bottle, and the first inlet / outlet is located at the bottom of the sample bottle. The first inlet / outlet 112 is threadedly connected to the bottle mouth 12. A sealing device 4 is provided inside the bottle mouth 12, and the sealing device 4 is sealed to the bottle mouth 12. A waterproof and breathable valve 113 is provided inside the exhaust port 111 to ensure that gas can freely enter and exit the sample bottle 1, while the water in the sample bottle 1 will not overflow.

[0032] like Figure 3-4As shown, the sealing device 4 includes a sealing element 41 and a spring 42. The sealing element 41 is used to seal the bottle mouth 12, and the spring 42 is configured to provide a restoring force to the sealing element 41. Specifically, the sealing element 41 includes a sealing rod 411 and a first sealing ring 412. The first sealing ring 412 is disposed at one end of the bottle mouth 12. The sealing rod 411 includes a sealing rod body 4111, a first protruding end 4112, and a second protruding end 4113. The first protruding end 4112 and the second protruding end 4113 are respectively disposed at both ends of the sealing rod body 4111. The second protruding end 4113 is provided with a sealing groove 4114 for the first sealing ring 412 to be placed. The spring 42 is sleeved on the sealing rod body 4111 and also has one end connected to the sealing rod body 4111. The sealing rod 4111 is configured to move away from the bottle mouth 12 under the action of external force and return to its original position under the action of the spring 42. Under the elastic force of spring 42, sealing rod 411 and first sealing ring 412 will seal the first inlet and outlet 112 of sample bottle 1, so that it is in a closed state.

[0033] like Figure 5 As shown, the lifting mechanism 2 includes a boss 21, a second sealing ring 22 and a sealing ring pressure plate 23, and the second sealing ring 22 and the sealing ring pressure plate 23 are fixedly arranged on the boss 21 in sequence.

[0034] The boss 21 has a placement space 211 for placing the first protruding end 4112. The placement space 211 has a protrusion 212, and the protrusion 212 has at least one through hole 213. The boss 21 also has a second inlet / outlet 214, which is connected to the through hole 213. Specifically, the second inlet / outlet 214 is connected to a water pipe. Under the action of the lifting mechanism 3, the lifting mechanism 2 moves towards the first inlet / outlet 112 of the sample bottle 1. The boss 21 lifts the sealing rod 411 away from the bottle mouth 12. At this time, the sample bottle 1 is unsealed and performs inlet / outlet operation. At this time, the second sealing ring fits and seals with the outer ring of the bottle mouth, ensuring the seal of the outer ring of the bottle mouth.

[0035] Preferably, the lifting mechanism 3 includes an electric push rod or a guide rail slide, which controls the height of movement to ensure that the sample bottle is not lifted when the structure is raised.

[0036] When no water inlet / outlet operation is performed, the sealing rod and the first sealing ring 412 seal the bottom of the bottle under the action of the spring force. When water inlet / outlet operation is required, the lifting mechanism 2 moves towards the bottle mouth under the action of the lifting mechanism 3. At this time, the protrusion 212 just contacts the first protruding end 4112 of the sealing rod 411, and the sample bottle 1 is still in a sealed state. The lifting mechanism 2 continues to move towards the bottle mouth under the action of the lifting mechanism 3. The protrusion 212 lifts the sealing rod 411 away from the bottle mouth, and there is a gap between the sealing rod 411 and the first sealing ring 412. At this time, the second sealing ring fits and seals with the outer ring of the bottle mouth. The sample bottle is still isolated from the external environment. When the bottle mouth is unsealed, the water sample can enter and exit the sample bottle 1 through the second inlet / outlet port 214 and the through hole 213.

[0037] like Figure 1 As shown, the inlet and outlet drainage device also includes a tray 5, which has placement holes for the first inlet and outlet 112. The sample bottle 1 has a triangular cross-section and is placed in a ring within the tray 5 by fitting the sample bottles 1 together. This allows for more sample bottles 1 to be placed in the same space, thus reducing the space required for placing the sample bottles and the overall volume of the water sampler. The inlet and outlet drainage device also includes a rotary motor 6, which drives the tray to rotate and move the target sample bottle to the lifting mechanism. When a sample bottle needs to be drained or inleted, the rotary motor 6 can be controlled to rotate and move the target sample bottle to the lifting mechanism. The lifting mechanism, under the action of the lifting mechanism, then pushes the boss into the sealing rod to perform the inlet and outlet drainage operation.

[0038] Preferably, to facilitate smoother tray rotation, a sliding device can be provided at the bottom of the tray to assist its rotation. The inlet and outlet drainage device also includes an identification device or positioning device for identifying or positioning the target sample bottle. The identification device includes, but is not limited to, limit switches and magnetic encoders.

[0039] The lifting mechanism 3, the jacking mechanism 2, and the tray 5 in this application are only described in terms of their installation positions. They are also connected to other devices for fixation, but will not be described in detail here. Example

[0040] This embodiment provides a self-draining and sealing inlet and outlet device for a water quality sampler. The difference from Embodiment 1 is that the exhaust port and the first inlet and outlet are both located on the top of the sample bottle. Example

[0041] like Figure 6As shown, this embodiment provides a self-draining and sealing inlet / outlet device for a water quality sampler. The difference from Embodiment 1 is that the lifting mechanism 2 includes a lifting rod 21a and a third sealing ring 22a. The lifting rod 21a is configured to press against the sealing rod away from the bottle mouth, and the third sealing ring 22a is configured to seal against the outer ring of the bottle mouth when the lifting rod presses against the sealing rod away from the bottle mouth. Under the action of the lifting mechanism 3, the lifting rod is pushed into the sealing device, pushing the sealing element 41 away from the bottle mouth. A water inlet is provided inside the lifting rod, and the water inlet is connected to a water pipe for inlet / outlet operations into the sample bottle. Example

[0042] This embodiment provides a self-draining and sealing inlet / outlet device for a water quality sampler. The difference from Embodiment 1 is that the exhaust port and the first inlet / outlet are both located on the top of the sample bottle, and the exhaust port 111 is also provided with a sealing device. The sealing rod in the exhaust port is pushed into the exhaust port by the lifting mechanism for exhaust operation, moving away from the bottle mouth, to perform the exhaust operation. In addition, since exhaust only requires moving the sealing rod away from the bottle mouth, there is no water inlet in the lifting rod in the lifting mechanism, or there is no need to provide a through hole 213 on the protrusion 212 in the lifting mechanism.
