Description

Technical Field

[0001] The utility model relates to the technical field of water sampling, and more specifically to a deep water sampling device for drinking water sources. Background Art

[0002] The deep water sampling device for drinking water sources is a professional device used to collect water samples from deep water bodies (such as lakes, reservoirs, groundwater wells, etc.) for water quality testing in environmental monitoring, and to ensure that the samples are not contaminated by the surface and maintain the water quality characteristics of the original water. Its core goal is to obtain representative, pollution-free deep water samples for water quality monitoring, scientific research analysis or safety assessment.

[0003] Chinese Patent Authorization Announcement No.: CN216349735U provides a deep water sampling and detection device. This solution benefits from the cooperation of a floating plate, a casing, a cable and a sampling detector. The sampling detector can be placed in deep water using a cable, and the magnetic attraction of an electromagnet and a sliding plug can be used for sampling. It can also be used in conjunction with a water quality detector body for timely detection. It is easy to use, and the cooperation of a fixed block, a clamping plate and a water-absorbing sponge can simply wipe the surface of the cable when the cable is gathered, which is beneficial to ensure the dryness of the cable surface and to avoid water from entering the casing as the cable is gathered, causing internal components to become damp and moldy, thereby helping to extend the service life of the equipment.

[0004] When sampling deep water, the above scheme needs to use an electromagnet to control the sealing and opening of the water inlet, but the sampling device works underwater. Using more electrical equipment for control is not only prone to sealing failure and damage, but also increases the production difficulty and manufacturing cost, which is not conducive to improving economic efficiency.

[0005] Therefore, in view of the above problems, a deep water sampling device for drinking water source is proposed. Utility Model Content

[0008] 2. Technical solution

[0009] To solve the above problems, the utility model adopts the following technical solutions.

[0010] An embodiment of the present application provides a deep water sampling device for a drinking water source, comprising: a floating ring, a sampling assembly, and a pulling rope. The floating ring floats on the water surface. The sampling assembly includes an outer sleeve and a sampling bucket. The outer sleeve is movably sleeved outside the sampling bucket. A bottom plate is fixedly connected to the bottom end of the sampling bucket, and a counterweight block is fixedly installed at the bottom end of the bottom plate. A clamping sleeve is fixedly installed at the top of the sampling bucket. One end of the pulling rope is detachably connected to the top of the sampling bucket through the clamping sleeve. The pulling rope is used to pull the sampling assembly to move. The sampling position is determined by the floating ring for the sampling assembly. The counterweight block is used to increase the mass of the sampling bucket so that the average density of the whole of the sampling bucket and the counterweight block is greater than the density of the outer sleeve, and thus the falling speed of the sampling bucket in the water is greater than the falling speed of the outer sleeve in the water.

[0011] In the above technical solution of the embodiment of the present application, it has at least the following technical effects:

[0012] After the sampling assembly is hoisted into the water by using the pulling rope, since the outer sleeve is movably sleeved at the outer end of the sampling bucket and the density of the outer sleeve is less than the average density of the sampling bucket installed with the counterweight block, after entering the water, the falling speed of the sampling bucket is greater than that of the outer sleeve. The water inlet one and the water inlet two on the sampling bucket will be exposed. During the falling process of the sampling assembly, water will continuously pour in from the water inlet one and flow out from the water inlet two. When the sampling assembly is pulled upward by the pulling rope, the sampling bucket will move upward first. When the top of the sampling bucket abuts against the inner top of the outer sleeve, the whole sampling assembly will be pulled upward. At the same time, it is sealed by the sealing ring one and the sealing ring two, and no water will enter during the rising process. Thus, sampling can be completed through the cooperation of the outer sleeve and the sampling bucket, reducing the structural complexity and the production and use costs.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figure 1 - Figure 5 , a deep water sampling device for a drinking water source provided by an embodiment of the present application, comprising: a floating ring 1, a sampling assembly 4 and a pulling rope 3. The floating ring 1 floats on the water surface. The sampling assembly 4 includes an outer sleeve 41 and a sampling bucket 45. The outer sleeve 41 is movably sleeved outside the sampling bucket 45. A bottom plate 42 is fixedly connected to the bottom end of the sampling bucket 45. A counterweight 43 is fixedly installed at the bottom end of the bottom plate 42. A clamping sleeve 413 is fixedly installed at the top of the sampling bucket 45. One end of the pulling rope 3 is detachably connected to the top of the sampling bucket 45 through the clamping sleeve 413. The pulling rope 3 is used to pull the sampling assembly 4 to move. The sampling assembly 4 determines the sampling position through the floating ring 1. The sampling bucket 45 increases its mass through the counterweight 43 so that the average density of the whole sampling bucket 45 and the counterweight 43 is greater than the density of the outer sleeve 41, so that the falling speed of the sampling bucket 45 in the water is greater than the falling speed of the outer sleeve 41 in the water.

[0033] The device in this solution is mainly used for sampling and detecting water sources in lakes or reservoirs. Compared with traditional samplers, it can sample in deep water. The floating ring 1 can be made by modifying a life buoy. The floating ring 1 is mainly used as a fixed carrier floating on the water surface. An installation assembly 2 and a plurality of connecting assemblies 5 are respectively arranged at the outer end of the floating ring 1. The installation assembly 2 is mainly used to fix it at a position closer to the shore through a rope. The connecting assembly 5 is used to connect a telescopic rod or a support frame to fix the floating ring 1 at a position far from the shore. A plurality of installation holes 6 are also opened at the outer end of the floating ring 1. The installation holes 6 are mainly used to install suspension rings so that it can be hoisted under buildings such as bridges for use in river basins.

[0034] After the sampling component 4 is connected by the pulling rope 3 and placed in water, the length of the pulling rope 3 can be prepared according to the required depth. After the sampling component 4 is hoisted into water by using the pulling rope 3, since the outer sleeve 41 is movably sleeved at the outer end of the sampling bucket 45 and the density of the outer sleeve 41 is less than the average density of the sampling bucket 45 installed with the counterweight 43, after entering water, the falling speed of the sampling bucket 45 is greater than that of the outer sleeve 41, and the water inlet one 47 and the water inlet two 48 on the sampling bucket 45 will be exposed. During the falling process of the sampling component 4, water will continuously pour in from the water inlet one 47 and flow out from the water inlet two 48. When the sampling component 4 is pulled upward by the pulling rope 3, the sampling bucket 45 will move upward first. When the top of the sampling bucket 45 abuts against the inner top of the outer sleeve 41, the whole sampling component 4 will be pulled upward. At the same time, it is sealed by the sealing ring one 46 and the sealing ring two 49, and no water will enter during the rising process. Thus, sampling can be completed through the cooperation of the outer sleeve 41 and the sampling bucket 45, reducing the structural complexity and the production and use costs, and improving the economy.

[0035] Please refer to Figure 1 and Figure 2 As shown in FIGS. Figure 1 and Figure 2 , connection components 5 and mounting components 2 are respectively arranged at the outer ends of the floating rings 1. The connection component 5 includes a collar one 51 which is sleeved at the outer end of the floating ring 1, and a connection head 52 is fixedly installed at the outer end of the collar one 51. Mounting holes 6 are arranged at the outer ends of the floating rings 1.

[0036] The mounting component 2 includes a plurality of brackets 21 distributed annularly. One ends of the plurality of brackets 21 are fixedly connected to each other, a rope passing ring 25 is installed at the connection part of the plurality of brackets 21, and the pulling rope 3 passes through the rope passing ring 25.

[0037] Pulleys 24 are fixedly installed at the outer ends of the brackets 21. One end of a bracket 21 is fixedly connected to a collar two 22 which is sleeved at the outer end of the floating ring 1. A backing plate 23 is fixedly installed at the top of the collar two 22. The pulling rope 3 successively passes over the pulley 24 and the backing plate 23, and a buckle 26 is installed at the outer end of the collar two 22.

[0038] The connection component 5 in this solution is mainly composed of the collar one 51 and the connection head 52. The collar one 51 is used for sleeving on the floating ring 1, while the connection head 52 is used for externally connecting a telescopic rod or a long rod and connecting them through a pin or a bolt, so that the floating ring 1 can be arranged in an area far from the shore, facilitating sampling of water at different positions.

[0039] The installation component 2 is mainly composed of one - end connection of multiple brackets 21. At the other ends of the multiple brackets 21, a second collar 22 is fixed. The second collar 22 is also sleeved on the outer end of the floating ring 1. At the top of the second collar 22, a backing plate 23 is fixed, which is mainly used to carry the pull rope 3. At the outer end of the bracket 21, a buckle 26 is installed. The buckle 26 is an existing U - shaped buckle, which can be used to connect ropes. By connecting multiple ropes to multiple buckles 26 respectively and then fixing the ropes on the shore to pull the floating ring 1, the floating ring 1 can be fixed around the shore, and sampling can be carried out in areas with deeper shores such as reservoirs.

[0040] A pulley 24 is fixed at the outer end of the bracket 21. At the same time, a rope - passing ring 25 is fixed at the connection of the multiple brackets 21. The middle of the rope - passing ring 25 is hollow, so that the pull rope 3 can pass through. Then the pull rope 3 passes over the pulley 24 and the backing plate 23, enabling the staff to pull or release the pull rope 3 on the shore to control the up - and - down movement of the sampling component 4 in the water.

[0041] Through the cooperation of the buckle 26, the connection component 5 and the installation hole 6, sampling can be carried out in different waters and positions.

[0042] Please refer to Figure 3 - Figure 5 On the outer surface of the sampling bucket 45, a first water inlet 47 distributed in a ring shape is provided. On the top of the sampling bucket 45, a second water inlet 48 distributed in a ring shape is provided. Both the second water inlet 48 and the first water inlet 47 are connected to the inside of the sampling bucket 45.

[0043] A first sealing ring 46 is fixedly installed at the outer end of the bottom plate 42. A first sealing groove 414 adapted to the first sealing ring 46 is provided at the bottom of the outer sleeve 41. A second sealing ring 49 is fixedly installed at the top of the sampling bucket 45. A second sealing groove 411 adapted to the second sealing ring 49 is provided at the inner top of the outer sleeve 41.

[0044] A limiting ring 410 is fixedly connected to the outer end of the sampling bucket 45. A limiting groove 412 adapted to the limiting ring 410 is provided on the inner wall of the outer sleeve 41. A water - discharging mechanism 44 connected to the inside of the sampling bucket 45 is provided at the bottom of the bottom plate 42. The water - discharging mechanism 44 is mainly composed of a sampling port and a lid threadedly connected to the sampling port, so that the water inside can be discharged along the sampling port.

[0045] The sampling component 4 in this solution is mainly used to sample water after sinking into the water. The sampling component 4 is a double-layer structure, mainly composed of an outer sleeve 41 and a sampling bucket 45. The outer sleeve 41 is movably sleeved on the outer end of the sampling bucket 45 and can move up and down. Both the outer sleeve 41 and the sampling bucket 45 are made of polypropylene PP plastic with a density of 0.9–0.92 g / cm³, making their density slightly lower than that of water. A bottom plate 42 is fixed at the bottom of the sampling bucket 45, and a counterweight 43 is fixed at the bottom of the bottom plate 42. The counterweight 43 is made of a substance with a relatively high density such as a lead block or a cement block. Through the weight of the counterweight 43, the average density of the sampling bucket 45 can be made greater than that of water, and the downward movement of the sampling bucket 45 can drive the outer sleeve 41 to move downward.

[0046] A clamping sleeve 413 is fixed at the top of the sampling bucket 45. The clamping sleeve 413 is composed of a fixed sleeve and a movable cover. Pass the pull rope 3 through the movable cover and tie a knot, and then thread the movable cover onto the fixed sleeve, so that one end of the pull rope 3 can be detachably connected to the clamping sleeve 413. A plurality of annularly equally spaced water inlets one 47 are provided on the outer periphery of the sampling bucket 45, and a plurality of annularly equally spaced water inlets two 48 are provided at the top of the sampling bucket 45. Both the water inlet two 48 and the water inlet one 47 are connected to the inside of the sampling bucket 45. Through the water inlet one 47 and the water inlet two 48, water can enter the inside of the sampling bucket 45.

[0047] A sealing ring one 46 is fixed at the outer edge of the bottom plate 42, and a sealing groove one 414 is provided at the bottom edge of the outer sleeve 41. The sealing ring one 46 and the sealing groove one 414 are adapted to each other, and sealing can be achieved when they are abutted. A sealing ring two 49 is fixed at the top of the sampling bucket 45. The sealing ring two 49 is located inside the plurality of annularly distributed water inlets two 48. A sealing groove two 411 is provided at the inner top of the outer sleeve 41. When the sealing ring one 46 and the sealing groove one 414 are abutted, the sealing ring two 49 and the sealing groove two 411 will also be abutted to achieve sealing. Through the simultaneous sealing of the upper and lower parts, the water inlet one 47 and the water inlet two 48 can be sealed.

[0048] At the same time, a limiting ring 410 is fixed at the outer end near the top of the sampling bucket 45, and a limiting groove 412 is provided on the inner side of the outer sleeve 41. The limiting groove 412 cooperates with the limiting ring 410 to prevent the sampling bucket 45 from detaching from the outer sleeve 41 and play a limiting role.

[0049] Working principle: When the sampling assembly 4 is placed in water, since the density of the outer sleeve 41 is slightly smaller than that of water, the sampling barrel 45 moves downward first and then cooperates with the limiting groove 412 through the limiting ring 410. When the water inlet 1 47 is fully exposed, the outer sleeve 41 will be driven to move downward. At this time, since the water inlet 2 48 and the water inlet 1 47 are open, water can continuously enter from the water inlet 1 47 and flow out from the water inlet 2 48. When the predetermined depth is reached, it needs to be still for a period of time. At this time, the sampling barrel 45 will maintain a downward movement trend and be pulled by the pull rope 3, while the outer sleeve 41 will maintain an upward floating trend and be held by the limiting ring 410 is restricted from escaping from the sampling barrel 45, so that water at a predetermined depth remains stable and continues to enter the sampling barrel 45. When it is pulled upward by the pull rope 3, the pulling speed needs to be slightly faster at this time, so that the rising speed of the sampling barrel 45 is greater than the floating speed of the outer sleeve 41 due to the density difference, so that the sealing ring 46 on the bottom plate 42 fits with the sealing groove 414 at the bottom of the outer sleeve 41, and the sealing ring 49 fits with the sealing groove 411 to achieve sealing. During the ascent, water from other depths will not be poured into the sampling barrel 45 to cause influence. Finally, the water can be released through the water discharge mechanism 44 at the bottom of the bottom plate 42.
