Description

Technical Field

[0001] This utility model relates to the field of water conservancy project management equipment, and in particular to a water sample collector for water conservancy project management. Background Technology

[0002] Water sampling is a crucial step in water conservancy project management, aiming to monitor water quality changes and assess pollution sources and their impacts. One existing water sampling device consists of a sampling bucket and a floating traction mechanism. After the entire device is submerged in the water, the sampling bucket sinks under gravity, while the floating traction mechanism uses buoyancy to open the seal at the bottom of the sampling bucket, allowing liquid from the water to enter and be collected.

[0003] However, existing water samplers of this type do not have a corresponding filtration structure when the water sample enters the sampling bucket, causing impurities in the water to also enter the sampling bucket. After these impurities accumulate in the sampling bucket, they not only affect the accuracy of subsequent sampling but also cause blockages in the opening and closing of the sealing parts during the subsequent sampling process, resulting in sampling failure. In view of this, this solution proposes a water sampler for water conservancy project management to solve the above problems. Utility Model Content

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figure 1-5 The present invention provides the following technical solution:

[0030] Example 1: This utility model provides a water sampler for water conservancy project management, comprising:

[0031] The sampling barrel 1 has a sampling port at the bottom and a filter structure inside the sampling port. The top and bottom of the sampling barrel 1 are fixedly connected to the reinforcing plate 101. The filter structure is connected to the middle of the reinforcing plate 101 at the bottom of the sampling barrel 1. Multiple reinforcing rods 102 are fixedly connected to the opposite side of the multiple reinforcing plates 101. The top of the sampling barrel 1 and through the reinforcing plate 101 has a guide hole 103. Multiple connecting lugs 3 are fixedly connected to the top edge of the reinforcing plate 101.

[0032] It should be noted that this scheme is equipped with two sets of reinforcing plates 101, which are fixedly connected to the top and bottom of the sampling barrel 1 respectively. The two ends of multiple reinforcing rods 102 are arranged and fixed around the opposite side of the two sets of reinforcing plates 101. The reinforcing plates 101 and reinforcing rods 102 are used to stabilize the structure of the sampling barrel 1. In this scheme, the sampling port passes through the middle of the reinforcing plate 101 located at the bottom of the sampling barrel 1, thereby connecting to the filter structure. The connecting lugs 3 are used for the traction and lifting of the sampling barrel 1.

[0033] Specifically, the filter structure includes a filter bucket 2, which is inserted into the bottom of the sampling bucket 1, and the bottom of the filter bucket 2 is fixedly inserted into the middle of the reinforcing plate 101. Multiple filter holes 201 are opened around the outer wall of the filter bucket 2.

[0034] It should be noted that the opening of the filter bucket 2 is set downwards, and the filter bucket 2 is welded and fixed to the bottom of the sampling bucket 1. With the setting of the filter bucket 2, when water needs to enter the sampling bucket 1, it needs to enter the filter bucket 2 first. Then, through the setting of the filter hole 201, solid impurities such as branches and leaves in the water can be filtered and blocked to ensure that the liquid enters the sampling bucket 1.

[0035] Example 2: This utility model provides a sealing mechanism, which is applied to a water sampler for water conservancy project management in Example 1. The sealing mechanism includes a traction rod 4, a sealing component, and a connecting component. The traction rod 4 is inserted and connected to the middle of the sampling bucket 1. The sealing component and the connecting component are respectively set at both ends of the traction rod 4. The sealing component is inserted and connected to the filter structure. The bottom of the traction rod 4 is inserted and connected to the middle of the filter bucket 2. The sealing component is inserted and connected inside the filter bucket 2. The outer wall of the traction rod 4 is slidably inserted and connected to the inner wall of the guide hole 103.

[0036] Specifically, the closure includes:

[0037] The sealing plate 5 is detachably connected to the bottom of the traction rod 4, and the sealing plate 5 is interlocked with the inner wall of the filter bucket 2.

[0038] The scraping ring 501 is fixedly sleeved on the outer wall of the closed plate 5, and the outer ring wall of the scraping ring 501 is in contact with the inner wall of the filter hopper 2.

[0039] It should be noted that the sealing plate 5 is connected to the bottom of the traction rod 4 by bolts. The scraping ring 501 is made of rubber material, and its area near the center of the ring is reduced in thickness from the outer ring wall to achieve flexible deformation. When the sealing plate 5 moves in the filter hopper 2, it drives the scraping ring 501 to move synchronously and scrape the inner wall of the filter hopper 2, thereby scraping away the debris accumulated at the filter hole 201. At the same time, the fit between the scraping ring 501 and the inner wall of the filter hopper 2 controls the size of the sampling port opening of the filter hopper 2 and the sampling bucket 1.

[0040] Specifically, the connector includes a connecting ring 401, which is fixedly connected to the top of the traction rod 4.

[0041] In embodiment three, this utility model provides a traction mechanism, which is applied to a water sampler for water conservancy project management in embodiment one and a closed mechanism in embodiment two. The traction mechanism is fixedly connected to the connecting piece. The traction mechanism is used to pull the connecting piece by the buoyancy of the sampled water. The connecting ring 401 is used to connect the traction mechanism.

[0042] Specifically, the traction mechanism includes:

[0043] The traction rope 6 has one end for connecting to the hanging ring 401, and a connecting ring 601 is provided between the traction rope 6 and the connecting hanging ring 401.

[0044] The outer wall of the float 7 is fixedly connected to the other end of the traction rope 6, and multiple lifting lugs 701 are fixedly connected to the outer wall of the float 7.

[0045] It should be noted that the float 7 floats on the water surface due to buoyancy. When the sampling bucket 1 moves downwards into the water under the action of gravity, the buoyancy of the float 7 pulls the traction rope 6 upwards. The traction rope 6, through the connecting ring 601 and the connecting hanging ring 401, pulls the traction rod 4 upwards relative to the sampling bucket 1. At this time, the traction rod 4 first drives the sealing plate 5 and the scraping ring 501 upwards relative to the sampling bucket 1, and the sampling port opens to collect water samples. Throughout the process, the sampling bucket 1 descends into the water, causing the traction rope 6 to straighten. Once the gravity of the descending sampling bucket 1 and the upward pull of the buoyancy of the float 7 are axially transmitted at the traction rope 6, the traction rope 6 can be used to lift and pull the traction rod 4 and the sealing component, thereby activating the water sample collection. Therefore, in actual setups, the sinking depth of the sampling bucket 1 in the water can be adjusted according to the length of the traction rope 6, thus enabling the collection of water samples at different depths.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
