Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection monitoring, and in particular to a rapid sampling device for environmental protection monitoring. Background Technology
[0002] Environmental protection monitoring refers to determining environmental quality (or pollution level) and its changing trends by measuring representative values of factors affecting environmental quality. In environmental protection monitoring, sampling devices are needed to collect soil samples from different layers and locations in order to comprehensively assess the soil pollution situation.
[0003] A search revealed Chinese Patent Publication No. CN216669331U, which discloses a soil monitoring device for environmental protection. The device includes a sampling device, a fixing device, and an installation device. The lower part of the sampling device is detachably connected to the fixing device, and the upper part of the sampling device is provided with a connecting handle. Several installation devices are provided, each connected to both ends of the connecting handle. The fixing device limits the position of the sampling device, and by connecting multiple installation devices to the lower side of the connecting handle, workers can press the sampling device downwards using a foot pedal. Furthermore, the installation devices are easy to assemble and disassemble, saving significant working time.
[0004] In the existing technology, the above-mentioned device can make it more convenient for staff to take samples by applying pressure with their hands and feet. However, the device needs to be disassembled and installed one by one under different pressing conditions. Although the installation device is easy to disassemble and install, it lacks a fixing measure. If the staff's foot stepping direction is off, it will cause the pedals to detach, affecting the sampling efficiency. Therefore, a rapid sampling device for environmental protection monitoring is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a rapid sampling device for environmental protection monitoring, which aims to improve the problem of unstable use of the pedal in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid sampling device for environmental protection monitoring, comprising a connecting tube, a handle slidably connected to the outer wall of the connecting tube, a retaining ring provided at the right end of the handle via an elastic element, a fixing block fixedly connected to the outer wall of the retaining ring, a retaining groove provided on the outer wall of the connecting tube, and an adjustment component provided at the bottom end of the connecting tube.
[0007] As a further description of the above technical solution:
[0008] The adjustment assembly includes a fixed tube, the inner wall of which is threaded and connected to a threaded rod, and the inner wall of the fixed tube is slidably connected to a movable tube.
[0009] As a further description of the above technical solution:
[0010] The bottom end of the threaded rod is rotatably connected to the top end of the moving tube.
[0011] As a further description of the above technical solution:
[0012] The elastic element includes a return spring, one end of which is fixedly connected to the right end of the handle, and the other end of which is fixedly connected to the right end of the retaining ring.
[0013] As a further description of the above technical solution:
[0014] The retaining ring is slidably connected to the inner wall of the handle.
[0015] As a further description of the above technical solution:
[0016] The fixing block is slidably connected to the inner wall of the handle.
[0017] As a further description of the above technical solution:
[0018] The retaining rings are provided in two sets, and the two sets of retaining rings are symmetrically distributed on the inner wall of the handle.
[0019] As a further description of the above technical solution:
[0020] The retaining ring is inserted into the inner wall of the retaining groove.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the locking ring and the slot can be separated to release the handle's limiting position and adjust its position according to one's own physical strength and operating habits. This allows for switching between hand-pressing and foot-pressing force, eliminating the need for multiple handle disassemblies. Furthermore, the locking ring and slot ensure the stability of the handle when stepped on. Additionally, the handle can be easily disassembled and stored, greatly reducing its overall space occupation when the device is not in use, making it convenient for transportation and storage.
[0023] 2. In this utility model, by rotating the moving tube, the threaded rod is driven to rotate clockwise on the inner wall of the fixed tube, thereby increasing the space between the fixed tube and the moving tube. This allows for flexible adjustment of the space size according to the actual sampling situation, and can well adapt to different soil sample collection volume requirements.

[0029] 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.
[0030] Reference Figures 1-3 This utility model provides an embodiment of a rapid sampling device for environmental protection monitoring, including a connecting pipe 1. A handle 2 is slidably connected to the outer wall of the connecting pipe 1. The handle 2 allows the sampling personnel to press it with their hands, or it can be moved to a lower position for easy foot pressure. A retaining ring 4 is provided at the right end of the handle 2 via an elastic element. A fixing block 5 is fixedly connected to the outer wall of the retaining ring 4. The retaining ring 4 can be moved laterally along the inner wall of the handle 2 by the fixing block 5. A groove 6 is provided on the outer wall of the connecting pipe 1. The groove 6 and the retaining ring 4 have the same shape, allowing the retaining ring 4 to be locked on the inner wall of the groove 6. An adjustment component is provided at the bottom end of the connecting pipe 1.
[0031] Reference Figure 1 and Figure 3 The adjustment assembly includes a fixed tube 7, through which a threaded rod 8 is threadedly connected. A slot corresponding to the threaded rod 8 is opened on the inner wall of the fixed tube 7, allowing the threaded rod 8 to move along the inner wall of the fixed tube 7. A movable tube 9 is slidably connected to the inner wall of the fixed tube 7. The fixed tube 7 and the movable tube 9 form the entire sampling head. The bottom end of the threaded rod 8 is rotatably connected to the top end of the movable tube 9.
[0032] Reference Figures 1-3The elastic element includes a return spring 3, one end of which is fixedly connected to the right end of the handle 2. When the retaining ring 4 moves to the right, it compresses the return spring 3. During reset, the elastic force of the return spring 3 carries the retaining ring 4 back to its original position. The other end of the return spring 3 is fixedly connected to the right end of the retaining ring 4. The retaining ring 4 is slidably connected to the inner wall of the handle 2. The handle 2 has a corresponding slot for the retaining ring 4, allowing the retaining ring 4 to move laterally along the inner wall of the handle 2. The fixing block 5 passes through and is slidably connected to the inner wall of the handle 2. Figure 1 As shown, the handle 2 has a slot corresponding to the fixing block 5, which allows the fixing block 5 to move along the slot. Two sets of retaining rings 4 are provided, and the two sets of retaining rings 4 are symmetrically distributed on the inner wall of the handle 2. The retaining rings 4 are inserted into the inner wall of the retaining groove 6.
[0033] Working principle: First, when it is necessary to adjust the space between the fixed tube 7 and the moving tube 9, simply rotate the threaded rod 8 to slide the moving tube 9 down along the inner wall of the fixed tube 7, thereby increasing the space between the fixed tube 7 and the moving tube 9, which can accommodate more soil samples. The space between the moving tube 9 and the fixed tube 7 can be adjusted according to the actual sampling situation.
[0034] When the fixed tube 7 and threaded rod 8 are inserted into the soil, workers can apply pressure by pressing the handle 2 with their hands to make the connecting tube 1, fixed tube 7, and moving tube 9 continue to move downward. If the force applied by hand needs to be changed to the force applied by foot, simply move the fixed block 5 to the right to move the retaining ring 4 and compress the return spring 3, so that the retaining ring 4 separates from the groove of the retaining groove 6. The entire handle 2 can then be moved up and down along the outer wall of the connecting tube 1 and adjusted to the designated position according to the actual stepping situation. When a limit is needed, simply release the fixed block 5 and use the reverse elastic force of the return spring 3 to reset the retaining ring 4, so that the retaining ring 4 can be inserted into the groove of the corresponding retaining groove 6. When the handle 2 needs to be disassembled and stored, simply release the limit of the handle 2 and move the handle 2 upward to detach it from the connecting tube 1.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
