Description

Technical Field

[0001] The invention relates to the technical field of seawater sampling, in particular to an on-site water sample dispensing device. Background Art

[0002] Obtaining representative seawater samples from the marine environment and analyzing and measuring them is an important part of marine environmental investigation. At present, seawater samples are usually collected by using a water sampler, that is, the water sampler is thrown into the water, and the water inlet at the bottom is automatically opened. Water samples at different depths can be collected by tying a rope on the top, water enters from the bottom and flows out from the top. When the water sampler stops at different depths, the water samples collected are the water samples at this level.

[0003] The water samples collected by the water sampler need to be divided into water sample bottles on site for storage and transportation. However, the existing water sampler can only fill one water sample bottle at a time, and the filling efficiency is low. In addition, since the bottle mouth of the sampling bottle is small and the water outlet of the water sampler is on the side, it is not easy to align with the bottle mouth of the water sample bottle, making water sample filling inconvenient and easily causing water samples to spill. Summary of the invention

[0004] The present invention aims to solve the above problems existing in the water sampler of the prior art and provides an on-site water sample filling device which has a simple structure, is easy to carry and use, can fill multiple water sample bottles at the same time, has high filling efficiency, and is not easy to spill water samples.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an on-site water sample dispensing device of the present invention comprises a through barrel body and a bottom sealing plate arranged at the bottom of the barrel body, the bottom of the bottom sealing plate is fixed with a supporting foot, the bottom surface of the bottom sealing plate is provided with a mounting groove, a conical push head is provided in the mounting groove, a pressure rod is provided in the barrel body, the pressure rod passes through the bottom sealing plate and is slidably and sealedly matched with the bottom sealing plate, the lower end of the pressure rod is fixedly connected with the conical push head, a longitudinal tightening spring is provided between the pressure rod and the top surface of the bottom sealing plate, at least two guide holes are circumferentially provided in the groove wall of the mounting groove, an advance and retreat column is provided in the guide hole, the advance and retreat column is sealed and slidably matched with the guide hole, the upper and lower sides of the guide hole are provided with a water inlet hole and a water outlet hole, a connecting hole is provided on the advance and retreat column, a ball head is provided at the outer end of the advance and retreat column, a part of the advance and retreat column located between the ball head and the groove wall of the mounting groove is provided with a transverse tightening spring, the ball head always keeps in contact with the conical surface of the conical push head, and a bottle placing plate for placing a water sample bottle is provided below the bottom sealing plate. The on-site water sample dispensing device of the present invention is used for dispensing water samples on-site. When the longitudinal pressing spring is not subjected to external force, the connecting hole is staggered with the water inlet hole and the water outlet hole, and the water in the barrel cannot be discharged. When the pressure rod is pressed down, the conical push head squeezes the ball head outward to make the advance and retreat column retract inward into the guide hole. When the connecting hole is connected with the water inlet hole and the water outlet hole, the water in the barrel can be discharged through the water inlet hole, the connecting hole and the water outlet hole. The bottle placing plate is used for placing the water sample bottle, and the discharged water sample is directly poured into the water sample bottle. When the filling is completed, the pressure rod is released, the longitudinal pressing spring is restored, and the conical push head is driven to move upward, so that the advance and retreat column is withdrawn from the guide hole outward until the connecting hole is staggered with the water inlet hole and the water outlet hole, and the water sample in the barrel cannot be discharged. The present invention can realize the filling of multiple water sample bottles at the same time, with high filling efficiency. At the same time, it has a simple structure, is easy to carry and use, and is very suitable for outdoor on-site use.

[0006] Preferably, a fixing plate is fixed in the barrel body, the pressure rod passes through the fixing plate and slides with the pressure rod, a spring limit seat is provided on the pressure rod, and the longitudinal pressing spring is sleeved on the pressure rod between the spring limit seat and the top surface of the bottom plate. The fixing plate is used to fix the pressure rod, reduce shaking, and improve the stability of the pressure rod; in order to prevent debris from clogging the water inlet, a filter can be set in the barrel body to filter the water sample.

[0007] Preferably, the fixing plate is provided with a guide sleeve, the pressure rod passes through the guide sleeve and slides with the guide sleeve, and when the longitudinal pressing spring is not subjected to external force, the spring limit seat abuts against the lower end surface of the guide sleeve. The guide sleeve plays a guiding role, so that the pressure rod can maintain vertical linear motion, while extending the guiding distance, and cooperates with the spring limit seat to limit the upward stroke of the pressure rod.

[0008] Preferably, a handle is provided at the upper end of the pressure rod.

[0009] Preferably, a detachable water pipe is provided at the lower side of the water outlet, which makes drainage more accurate and can directly pour water into the water sample bottle, thus reducing water sample spillage.

[0010] Preferably, an anti-rotation mechanism is provided between the advancing and retreating cylinder and the guide hole to prevent the advancing and retreating cylinder from rotating. The anti-rotation mechanism prevents the advancing and retreating cylinder from rotating, so as to avoid the communication hole being unable to accurately communicate with the water inlet hole and the water outlet hole or being misaligned.

[0011] Preferably, the anti-rotation mechanism comprises an open guide groove arranged on the hole wall of the guide hole, and the advancing and retreating column is provided with a limit slider matched with the open guide groove. The limit slider slides along the open guide groove, has a simple structure, can effectively prevent the advancing and retreating column from rotating, and can ensure that the connecting hole is accurately connected with the water inlet hole and the water outlet hole or staggered.

[0012] Preferably, the bottle placing plate is concave at a position corresponding to the water outlet to form a bottle placing groove, which plays a positioning role, can not only realize the stable placement of the water sample bottle, but also ensure that the bottle mouth of the water sample bottle can be aligned with the water outlet.

[0013] Preferably, a through hole is provided at the top of the installation groove, the pressure rod passes through the through hole and is slidably fitted with the through hole, and a sealing ring is provided on the inner wall of the through hole.

[0014] Preferably, the inner end surface of the advancing and retreating cylinder is set as a spherical surface. The spherical surface plays a guiding role, facilitating the assembly and advancement and retreat of the advancing and retreating cylinder.

[0015] Therefore, the present invention has the following beneficial effects: (1) Simple structure, easy to carry and use, suitable for outdoor use; (2) It can fill multiple water sample bottles at the same time with high filling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
