Abstract
Description
Technical Field
[0001] This utility model relates to the field of pumping equipment technology, specifically to a pumping device for hydrogeological testing. Background Art
[0002] In hydrogeological experiments, pumping devices play a crucial role. However, traditional pumping devices have many problems. On the one hand, during operation, especially in complex field environments, pumping devices are often subjected to various vibrations and impacts, including the self-vibration of the motor, water flow impact, and external interference from surrounding geological activities. These vibrations and impacts can easily affect the stability of the rotating parts inside the device. Traditional devices lack effective buffering and protection mechanisms, making key components such as the rotating shaft prone to damage, leading to frequent device failures and affecting the continuity of pumping operations. On the other hand, there is a lack of reasonable protective structures to limit the abnormal displacement of internal components under vibration and other conditions. When subjected to large external forces, the rotating shaft may shift, affecting the normal rotation of the impeller, reducing pumping efficiency, and may even cause the impeller to collide with components such as the pump body, resulting in component damage, increased maintenance costs and time, and seriously hindering the smooth progress of hydrogeological experiments.
[0003] By designing this pumping device for hydrogeological experiments, the above problems are effectively solved through the coordinated action of the sliding device and the limiting device, thereby ensuring the stable operation of the pumping work. Utility Model Content

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0018] Example: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a pumping device for hydrogeological experiments, comprising: a base 1, a DC motor 2 fixedly connected to the outer wall of the top of the base 1, a pump body 3 disposed outside the DC motor 2, a rotating shaft 4 fixedly connected to the output end of the DC motor 2, and an impeller 5 fixedly connected to the end of the rotating shaft 4 away from the DC motor 2; a protective device 6, the outer wall of the protective device 6 fixedly connected to the outer wall of the base 1, the protective device 6 being used to protect the rotating shaft 4; the protective device 6 includes a protective shell 61, protrusions 62 symmetrically fixedly connected to both sides of the protective shell 61, a flow guide frame 63 fixedly connected to the outer wall of the protrusions 62, a sliding device 64 slidably connected to the inner wall of the protective shell 61, and a limit device provided inside the protective shell 61. When the protective shell 61 is installed, the device 65 pushes the sliding device 64 towards the limiting device 65. Due to the rounded corners at the bottom of the limiting block 643 and the squeezing of the sliding groove 655, the pushing blocks 641 move closer to each other, which in turn drives the sliders to move closer to each other 642. At this time, under the positioning of the telescopic rod 644, the compression spring 645 is compressed and generates elastic force. When the limiting block 643 reaches the position of the limiting groove 654, the protective shell 61 contacts the top of the base 1. Since the compression spring 645 is compressed, the elastic force generated by the compression spring 645 will push the limiting block 643 to both ends of the limiting groove 654. At this time, the limiting block 643 is blocked by the connecting plate 653 and is difficult to detach, thus fixing the position of the protective shell 61.
[0019] The outer wall of the base 1 is fixedly connected to the outer wall of the pump body 3, the inner wall of the pump body 3 is rotatably connected to the outer wall of the rotating shaft 4, the inner wall of the pump body 3 is rotatably connected to the outer wall of the impeller 5, and the outer wall of the bottom of the protective shell 61 is in contact with the outer wall of the top of the base 1.
[0020] The sliding device 64 includes a telescopic rod 644, a compression spring 645 sleeved on the outside of the telescopic rod 644, sliders 642 fixedly connected to both ends of the telescopic rod 644, a push block 641 fixedly connected to the side wall of the slider 642, a limit block 643 fixedly connected to the outer wall of the bottom of the slider 642, the outer wall of the top of the slider 642 slidably connected to the top of the inner part of the protective shell 61, the outer wall of the push block 641 slidably connected to the inner wall of the protective shell 61, and both ends of the telescopic rod 644 fixedly connected to the inner wall of the slider 642. When the device vibrates or is subjected to external impact, the slider 642 of the sliding device 64 will slide on the inner wall of the protective shell 61. The compression spring 645 and the telescopic rod 644 work together. The compression spring 645 plays a buffering and shock-absorbing role, absorbing vibration energy, protecting the rotating shaft 4 and other internal components from excessive impact, and ensuring that the rotating shaft 4 rotates in a stable environment.
[0021] The limiting device 65 includes a fixing block 651, with a through hole 652 on the inner wall of the fixing block 651. A connecting plate 653 is symmetrically fixedly connected to the side wall of the fixing block 651. A limiting groove 654 is provided on the outer wall of the bottom of the connecting plate 653. A sliding groove 655 is provided on the outer wall of the top of the connecting plate 653. The sliding groove 655 is connected to the limiting groove 654. The outer wall of the top of the fixing block 651 is fixedly connected to the outer wall of the top of the base 1. The inner wall of the fixing block 651 is rotatably connected to the outer wall of the rotating shaft 4 through the through hole 652. The outer wall of the connecting plate 653 is slidably connected to the outer wall of the slider 642 through the sliding groove 655.
[0022] Working principle:
[0023] When in use, the base 1 provides stable support for the entire device. The DC motor 2 is fixed on the base 1. When the DC motor 2 is started, the rotating shaft 4 at its output end begins to rotate, driving the impeller 5 to rotate at high speed inside the pump body 3. When the impeller 5 rotates, it generates centrifugal force, which causes the water inside the pump body 3 to be thrown to the surroundings. At the same time, a low-pressure zone is formed in the center, thereby continuously drawing water from the water source into the pump body 3 from the flange position of the pump body 3, and then pumping the water out through the outlet on the side of the pump body 3, thus realizing the water pumping function.
[0024] The protective device 6 plays an important role in the operation of the device. The protective shell 61 is placed on the base 1. The protrusions 62 on both sides and the drainage frame 63 can guide the water that may splash out and the rainwater in the environment, preventing water from entering the device and affecting the rotating shaft 4 and causing corrosion.
[0025] Simultaneously, the sliding device 64 and the limiting device 65 cooperate to ensure that the protective shell 61 is stably placed on the base 1. When installing the protective shell 61, the sliding device 64 is pushed towards the limiting device 65. Due to the rounded corners at the bottom of the limiting block 643 and the compression of the sliding groove 655, the pushing blocks 641 move closer to each other, thereby driving the sliders to move closer to each other 642. At this time, under the positioning of the telescopic rod 644, the compression spring 645 is compressed and thus generates elastic force. When the limiting block 643 reaches the position of the limiting groove 654, the protective shell 61 contacts the base 1. At the top, the compression spring 645 is compressed. At this time, the elastic force generated by the compression spring 645 will push the limiting block 643 to both ends of the limiting groove 654. At this time, the limiting block 643 is blocked by the connecting plate 653 and is difficult to detach, thus fixing the position of the protective shell 61. When the protective shell 61 needs to be removed, simply pinch the pushing block 641 to make the slider 642 move closer to each other to detach. The sliding device 64 and the limiting device 65 cooperate with each other to enable the entire protection device 6 to continuously and effectively protect the rotating shaft 4 and ensure the stable operation of the pumping device.
[0026] Meanwhile, when the device vibrates or is subjected to external impact, the slider 642 of the sliding device 64 will slide on the inner wall of the protective shell 61. The compression spring 645 and the telescopic rod 644 work together. The compression spring 645 plays a buffering and shock-absorbing role, absorbs vibration energy, protects the rotating shaft 4 and other internal components from excessive impact, ensures that the rotating shaft 4 rotates in a stable environment, and extends the service life of the device.
[0027] The fixing block 651 of the limiting device 65 provides stable rotation support for the rotating shaft 4 through the through hole 652, ensuring that the rotating shaft 4 rotates smoothly and is difficult to deviate, so as to operate reliably in application scenarios such as hydrogeological tests and stably extract water samples for testing and analysis.
