Description

Technical Field

[0001] This utility model relates to the field of river sampling technology, specifically to an adjustable-depth river environment monitoring sampling device. Background Technology

[0002] The river environment monitoring sampling device is a sampling device used to detect the river environment. It is mainly used to collect sludge from the bottom of the river. Collecting sludge enables the monitoring of the river environment, and the sampling device allows the sludge inside the river to be removed.

[0003] In the existing technology, when sampling silt from different locations, the entire sampling device needs to be moved. Moving heavier devices is difficult and not convenient for users to move the device.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN219657215U) discloses a soil sampling device for environmental monitoring. This device includes a sampling box, a support rod fixedly connected to the sampling box, and a handle fixedly connected to the support rod. It also includes: a push plate symmetrically slidably connected inside the sampling box; a connecting rod fixedly connected to the push plate; a sliding rod fixedly connected to one end of the connecting rod passing through the top of the sampling box; and a groove formed on the support rod, wherein the sliding rod is slidably connected within the groove. During soil sampling, the device can clamp the soil sampled into the sampling box, preventing loose soil from slipping out of the sampling box when it is removed. Furthermore, after sampling, it facilitates the removal of the soil from the sampling box by the operator, preventing soil from adhering to the inner wall of the sampling box and being difficult to remove when sampling moist soil.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation, such as: different river channels have different silt depths, making it inconvenient to sample silt of different heights; the height adjustment of the sampling device is cumbersome and not conducive to the use of staff; and the sampling device is cumbersome to carry as a whole when transporting it. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable-depth river environment monitoring sampling device to solve the problems mentioned in the background art, such as the different silt depths in different rivers, the inconvenience of sampling silt at different heights, the cumbersome height adjustment of the sampling device, the inconvenience of use by staff, and the cumbersome overall carrying of the sampling device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-depth river environment monitoring sampling device, comprising a main rod and a positioning plate installed at the lower end of the main rod, wherein a sampling box is provided at the lower end of the positioning plate; a sleeve rod is sleeved on the upper end of the main rod, and a depth adjustment mechanism is provided inside the sleeve rod, wherein the depth adjustment mechanism includes through holes, and the through holes are evenly distributed on the surface of the sleeve rod; a folding rod is installed on the upper end of the main rod via a rotating shaft, and a folding transport mechanism is provided at the rear end of the folding rod, wherein the folding transport mechanism includes a mounting block, and the mounting block is located at the rear end of the folding rod.

[0008] Furthermore, a bidirectional threaded rod is rotatably mounted on the rear end of the positioning plate, and a drive rod is mounted on the middle end of the bidirectional threaded rod via a bevel gear set. A rotating sleeve is fitted on the upper end of the drive rod, and a rotating handle is mounted on the upper end of the rotating sleeve. Holes are evenly opened on the surface of the rotating handle, and positioning pins are embedded in the surface of the holes. The upper end of the rotating sleeve is rotatably mounted on the rear end of the sleeve rod, and the shape of the interior of the rotating sleeve is different from that of the drive rod.

[0009] Furthermore, the surface of the bidirectional threaded rod is threaded with a movable block, the lower end of which is fixedly installed on the upper end of the sampling box, and a limit rod is installed through the front end of the movable block, with the left and right sides of the limit rod installed on the upper end of the positioning plate.

[0010] Furthermore, the depth adjustment mechanism also includes a return spring, which is fixedly installed inside the main rod, and a button block is installed on the outside of the return spring.

[0011] Furthermore, the outer side of the button block is arc-shaped, and the button block is correspondingly arranged with the through hole.

[0012] Furthermore, the folding transport mechanism also includes an installation compartment, the front end of which is fixedly installed at the rear end of the sleeve rod, and a pull rod is installed through the rear end of the installation compartment. A locking block is installed at the front end of the pull rod. The locking block is inclined and corresponds to the position of the slot inside the installation block.

[0013] Furthermore, a positioning spring is fitted on the surface of the pull rod, and the inner and outer sides of the positioning spring are positioned between the mounting chamber and the locking block. An anti-slip pad is provided on the surface of the folding rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, the main rod is embedded into the river channel. When sludge collection is required, the sampling box at the bottom of the positioning plate is aligned with the sludge at the bottom of the river channel. Rotating the handle will drive the bidirectional threaded rod to rotate through the bevel gear set. When the bidirectional threaded rod rotates, it can drive the movable block connected by the surface thread. Under the limit of the limit rod, the movable block can drive the sampling box at the bottom. Due to the opposite threads at the left and right ends of the bidirectional threaded rod, the two tilted sampling boxes on the left and right can move inward to collect sludge at the bottom of the river channel, which is convenient for users to collect sludge and has a fast collection efficiency.

[0016] Furthermore, during use, an adjustment component is installed inside the sleeve rod fitted on the surface of the main rod. When it is necessary to adjust the height of the sampling device, press the button block to move it inward and compress the return spring until the appropriate height is achieved. Then, rotate the main rod in the opposite direction so that the button block on the main rod aligns with the nearest through hole. After alignment, the return spring engages the button block with the through hole, achieving convenient depth adjustment. This makes it easy for users to collect sludge at different depths, making sampling convenient.

[0017] 2. During use, the folding rod, which can rotate along the pivot, can be folded and stored. Conversely, when the folding rod is rotated to extend, rotating the folding rod causes the mounting block to embed into the mounting compartment. When the mounting block is embedded in the locking block, due to the shape of the locking block, the mounting block contacts the locking block and pushes the locking block to compress the positioning spring, automatically engaging in the slot for fixed installation. Conversely, when the pull rod is pulled, the locking block can disengage from the slot, thus achieving quick folding of the folding rod. The operation is simple and convenient, and it can be folded and carried, making it easy for users to transport and carry the river environment monitoring sampling device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figure 1 , Figure 2 , Figure 5 and Figure 6 The technical solution shown is an adjustable-depth river environment monitoring sampling device. To solve the problem of inconvenient collection of silt from inside the river, the device discloses: a main rod 1 and a positioning plate 2 installed at the lower end of the main rod 1. A sampling box 3 is set at the lower end of the positioning plate 2. A bidirectional threaded rod 18 is rotatably installed at the rear end of the positioning plate 2. A drive rod 16 is installed at the middle end of the bidirectional threaded rod 18 through a bevel gear set 17. A rotating sleeve 14 is sleeved on the upper end of the drive rod 16. A rotating handle 15 is installed on the upper end of the rotating sleeve 14. Holes are evenly opened on the surface of the rotating handle 15, and positioning bolts are embedded in the surface of the holes. The upper end of the rotating sleeve 14 is rotatably installed at the rear end of the sleeve rod 4. The shape of the interior of the rotating sleeve 14 is different from that of the drive rod 16. A movable block 19 is threadedly installed on the surface of the bidirectional threaded rod 18. The lower end of the movable block 19 is fixedly installed on the upper end of the sampling box 3. A limit rod 20 is installed through the front end of the movable block 19. The left and right sides of the limit rod 20 are installed on the upper end of the positioning plate 2.

[0027] In use, the main rod 1 is embedded into the riverbed. When sludge collection is required, the sampling box 3 at the bottom of the positioning plate 2 is aligned with the sludge at the bottom of the riverbed. At this time, the rotating handle 15 is rotated, which drives the rotating sleeve 14 to rotate. The rotation of the rotating sleeve 14 drives the drive rod 16 with the same internal shape. When the drive rod 16 rotates, it can drive the bidirectional threaded rod 18 to rotate through the bevel gear set 17. When the bidirectional threaded rod 18 rotates, it can drive the movable block 19 with the surface thread connection. Under the limit of the limit rod 20, the movable block 19 can drive the sampling box 3 at the bottom. Due to the opposite threads at the left and right ends of the bidirectional threaded rod 18, the two tilted sampling boxes 3 on the left and right can move inward to collect sludge at the bottom of the riverbed, which is convenient for users to collect sludge and has a fast collection efficiency.

[0028] Example 2: Figure 1 , Figure 2 and Figure 3 The technical solution shown, based on Embodiment 1, discloses the following to solve the problem of inconvenient depth adjustment: a sleeve rod 4 is sleeved on the upper end of the main rod 1, and a depth adjustment mechanism is provided inside the sleeve rod 4. The depth adjustment mechanism includes a through hole 7, which is evenly opened on the surface of the sleeve rod 4. The depth adjustment mechanism also includes a return spring 5, which is fixedly installed inside the main rod 1. A button block 6 is installed on the outside of the return spring 5. The outer shape of the button block 6 is arc-shaped, and the button block 6 is correspondingly arranged with the through hole 7.

[0029] In use, the sleeve rod 4 fitted on the surface of the main rod 1 has an adjustment component inside. When it is necessary to adjust the height of the sampling device, press the button block 6, which moves inward to squeeze the return spring 5. At this time, rotate the main rod 1 to disengage the button block 6 from the through hole 7. Then, pull the main rod 1 along the inside of the sleeve rod 4 to adjust the height until the appropriate height is reached. Then, rotate the main rod 1 in the opposite direction so that the button block 6 on the main rod 1 corresponds to the nearest through hole 7. After the correspondence, the return spring 5 locks the button block 6 into the through hole 7, achieving the effect of convenient depth adjustment. This makes it convenient for users to collect sludge at different depths, making sampling convenient.

[0030] Example 3: Figure 1 , Figure 2 and Figure 4The technical solution shown, based on Embodiment 2, discloses the following to address the problem of inconvenient carrying and transportation: a folding rod 8 is mounted on the upper end of the main rod 1 via a pivot, and a folding transport mechanism is provided at the rear end of the folding rod 8. The folding transport mechanism includes a mounting block 9, which is located at the rear end of the folding rod 8. The folding transport mechanism also includes a mounting compartment 10, the front end of which is fixedly mounted on the rear end of the sleeve rod 4. A pull rod 11 is installed through the rear end of the mounting compartment 10, and a locking block 12 is installed at the front end of the pull rod 11. The locking block 12 is inclined and corresponds to the internal slot of the mounting block 9. A positioning spring 13 is sleeved on the surface of the pull rod 11, and the inner and outer sides of the positioning spring 13 are located between the mounting compartment 10 and the locking block 12. An anti-slip pad is provided on the surface of the folding rod 8.

[0031] When in use, the folding rod 8, which can rotate along the pivot, can be folded and stored. Conversely, when the folding rod 8 is rotated to extend, rotating the folding rod 8 causes the mounting block 9 to be embedded in the mounting compartment 10. When the mounting block 9 is embedded in the locking block 12, due to the shape of the locking block 12, the mounting block 9 contacts the locking block 12 and pushes the locking block 12 to compress the positioning spring 13 until the locking block 12 corresponds to the slot inside the mounting block 9. Under the action of the positioning spring 13, the locking block 12 automatically engages in the slot for fixed installation. Conversely, when the pull rod 11 is pulled, the locking block 12 can be disengaged from the slot, thereby achieving quick folding of the folding rod 8. The operation is simple and convenient, and it can be folded and carried, making it easy for users to transport and carry the river environment monitoring sampling device.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
