Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically a soil and groundwater monitoring device. Background Technology

[0002] Groundwater monitoring refers to the process by which relevant management departments monitor parameters such as groundwater level and quality to track their dynamic changes in real time, thereby achieving long-term protection of groundwater. Currently, after the monitoring well is built, the monitoring device is usually lowered into the groundwater inside the well using a rope suspension method. However, as the diving depth increases, the monitoring device is prone to swaying and colliding with the well wall. Since the detection modules of the monitoring device are mostly precision sensors, directly suspending the monitoring modules with ropes would obviously lead to collisions and damage to the monitoring modules with the well wall. Therefore, effective anti-collision protection measures must be taken.

[0003] In the prior art, the text of Chinese Patent Publication No. CN117146876B entitled "A Groundwater Monitoring Device" describes a method where an elastic support component is installed on the outer shell of the monitoring module to abut against the well wall, thus keeping the groundwater monitoring device in a steady state with minimal fluctuations. While this method can reduce collision damage, it still has the following technical drawbacks: First, the structural design is complex, increasing manufacturing costs; second, the continuous friction between the elastic support component and the well wall presents two prominent problems: on the one hand, in deep water areas, the diving resistance of the device increases significantly with the increase of water pressure and buoyancy; on the other hand, uneven well walls further exacerbate frictional resistance, seriously affecting diving efficiency and potentially preventing the monitoring device from reaching the target monitoring depth. Therefore, these issues urgently need to be addressed. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a soil groundwater monitoring device with a simple and compact structure, which enables the monitoring device to quickly dive to the target monitoring depth. At the same time, the detection device also takes into account collision protection, effectively reducing the damage to its internal tightly packed sensors.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A soil groundwater monitoring device includes a monitoring module and a protective shell. The lower part of the protective shell has a cone-shaped structure with the cone end facing downward. The inner cavity of the protective shell is provided with a pull rope with both ends fixed to the center of the top and bottom of the protective shell, respectively. The monitoring module is fixed on the pull rope, and there is an anti-collision gap between the monitoring module and the shell wall of the protective shell. Water-permeable holes are arranged on the side wall of the protective shell near the monitoring module.

[0007] As a further embodiment of this utility model: the upper part of the protective shell has a conical structure with the conical end facing upward, and the monitoring module is arranged in the middle of the inner cavity of the protective shell.

[0008] As a further improvement of this utility model: energy-absorbing rubber is fixed to both the upper and lower parts of the inner cavity of the protective shell, the energy-absorbing rubber fills the upper and lower parts of the inner cavity of the protective shell, and the pull rope passes through the energy-absorbing rubber and is arranged in close contact with the energy-absorbing rubber.

[0009] As a further improvement of this utility model: the water-permeable hole is an elongated hole arranged vertically along the length direction of the hole, and at least two water-permeable holes are arranged circumferentially around the outer periphery of the protective shell.

[0010] As a further improvement of this utility model: from a top view, a buffer spring is fixed to the outer periphery of the protective shell, protruding to the outer edge of the protective shell.

[0011] As a further improvement of this utility model, the buffer springs are configured as at least two arranged circumferentially around the outer periphery of the protective shell.

[0012] As a further improvement of this utility model, a lifting ring is fixed at the top center of the protective shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The monitoring module is suspended and fixed within the protective shell via ropes. Water-permeable holes are located on the side wall of the protective shell near the monitoring module, allowing groundwater to enter the shell and be monitored by the module. When the protective shell collides with the well wall of the monitoring well, the shell primarily bears the impact force. Subsequently, the vibration during suspension via the ropes releases some energy, further reducing the rigid transmission of impact energy to the monitoring module and minimizing impact damage. Furthermore, the lower part of the protective shell has a conical shape with the tip pointing downwards, effectively reducing the diving resistance and ensuring rapid descent of the entire detection device. This simple and compact monitoring device allows for rapid descent to the target monitoring depth, while also providing collision protection, effectively reducing damage to the sensors within the detection module.

[0015] 2. The upper part of the protective shell has a conical shape with the cone tip pointing upwards, which effectively reduces the drag during the shell's ascent. Simultaneously, it creates a larger installation space in the middle of the shell, allowing the monitoring module to be positioned in the center of the shell's inner cavity. This eliminates the need for an excessively large conical angle, further reducing the drag during descent and ascent. Furthermore, this structural arrangement ensures that the distance between the monitoring module and both ends of the shell is approximately the same, guaranteeing the uniformity of energy release from the pull rope vibrations at the upper and lower parts of the monitoring module.

[0016] 3. Energy-absorbing rubber is fixed to both the upper and lower parts of the inner cavity of the protective shell. The energy-absorbing rubber fills the upper and lower parts of the inner cavity of the protective shell. The energy-absorbing rubber not only supports the inner cavity of the protective shell, but also absorbs energy after the protective shell collides with it. At the same time, the pull rope passes through the energy-absorbing rubber and is arranged in close contact with the energy-absorbing rubber, so that the energy after the protective shell collides with the pull rope is also absorbed by the energy-absorbing rubber, further reducing the energy transmitted to the monitoring module after the protective shell collides with the monitoring module, thereby more effectively reducing the damage to the monitoring module.

[0017] 4. From a top-down perspective, the outer periphery of the protective shell is fixed with buffer springs protruding to the outer edge of the protective shell. These springs can collide with the well wall before the protective shell collides with the well wall, and absorb the energy of the collision through the buffer springs, further reducing the impact energy transmitted to the protective shell.

[0022] 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.

[0023] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0024] The specific structure of this utility model is as follows: Figure 1-3As shown, its main structure includes a protective shell 10 and a monitoring module 40 arranged inside the cavity of the protective shell 10. Specifically, the top of the protective shell 10 is fixed to the slings of the hoisting structure for hoisting and lowering into the monitoring well; and the lower part of the protective shell 10 has a conical structure with the cone end pointing downwards, which effectively reduces the diving resistance of the protective shell 10 and ensures that the entire detection device can achieve rapid diving. In addition, the cavity of the protective shell 10 is provided with a pull rope 30, the two ends of which are fixed to the center of the top and bottom ends of the protective shell 10, respectively. The monitoring module 40 is fixed to the pull rope 30, and there is an anti-collision gap between the monitoring module 40 and the shell wall of the protective shell 10. Water permeable holes 11 are arranged on the side wall of the protective shell 10 near the monitoring module 40 to allow groundwater to enter the cavity of the protective shell 10 and be monitored by the monitoring module 40. The monitoring module 40 is fixed to the inner cavity of the protective shell 10 by means of a rope 30 suspended in the air. Even if the protective shell 10 collides with the well wall of the monitoring well, the protective shell 10 will mainly bear the impact force. Afterward, the vibration of the rope 30 in the air will release some of the energy, reducing the rigid transmission of the impact energy to the monitoring module 40 and preventing impact damage to the monitoring module 40. Furthermore, the anti-collision gap between the monitoring module 40 and the shell wall of the protective shell 10 is set to prevent collision damage between the monitoring module 40 and the shell wall of the protective shell 10 during the vibration of the rope 30.

[0025] Based on the above, such as Figure 1 As shown, the upper part of the protective shell 10 has a conical structure with the cone end pointing upwards, which effectively reduces the resistance during the ascent of the protective shell 10. At the same time, it creates a large installation space in the middle of the protective shell 10, and the monitoring module 40 is arranged in the middle of the inner cavity of the protective shell 10. This means that the protective shell 10 does not need an excessively large conical angle, further reducing the drag of the protective shell 10 during diving and floating. In addition, this structural arrangement also ensures that the distance between the monitoring module 40 and the two ends of the protective shell 10 is approximately the same, ensuring the uniformity of the energy release by the vibration of the pull rope 30 at the upper and lower parts of the monitoring module 40.

[0026] Energy-absorbing rubber 50 is fixed to both the upper and lower parts of the inner cavity of the protective shell 10. The energy-absorbing rubber 50 fills the upper and lower parts of the inner cavity of the protective shell 10. The energy-absorbing rubber 50 not only supports the inner cavity of the protective shell 10, but also absorbs energy after the protective shell 10 collides with it. At the same time, the pull rope 30 passes through the energy-absorbing rubber 50 and is arranged in close contact with the energy-absorbing rubber 50, so that the energy after the protective shell 10 collides and is conducted to the pull rope 30 will also be absorbed by the energy-absorbing rubber 50, further reducing the energy conducted to the monitoring module 40 after the protective shell 10 collides with it, thereby more effectively reducing the damage to the monitoring module 40.

[0027] Based on the above, such as Figure 2As shown, the permeable hole 11 is a long hole arranged vertically in the length direction of the hole. At least two permeable holes 11 are arranged circumferentially around the outer periphery of the protective shell 10 to ensure that groundwater enters the protective shell 10 and also ensures that the groundwater can flow inside the protective shell 10, preventing the groundwater in the inner cavity of the protective shell 10 from becoming "dead water" and ensuring the accuracy of the monitoring module 40 during the monitoring process.

[0028] Furthermore, to further ensure the protective effect of the protective shell 10, from a top-down view, a buffer spring 20 protruding to the outer edge of the protective shell 10 is fixed to its outer periphery. Preferably, the buffer spring 20 is made of materials such as copper, nickel-based alloy, or stainless steel, which have high strength and corrosion resistance. By setting the buffer spring 20, the protective shell 10 can collide with the well wall before colliding with it, and the buffer spring 20 absorbs and buffers the impact energy, further reducing the impact energy transmitted to the protective shell 10.

[0029] like Figure 3 As shown, at least two buffer springs 20 are arranged circumferentially around the outer periphery of the protective shell 10 to increase the distribution area of ​​the buffer springs 20 on the outer periphery of the protective shell 10, and to ensure that the buffer springs 20 can absorb energy and buffer the impact of the protective shell 10 as much as possible.

[0030] Based on the above, such as Figure 1 As shown, a lifting ring 60 is fixed at the top center of the protective shell 10 for fixing the protective shell 10 to the lifting cable.
