Description

Technical Field

[0001] This utility model relates to the field of water level measurement technology, specifically a precise water level measurement device for a ground inclined well. Background Technology

[0002] The inclined shaft water level measuring device is a specialized device designed for the special structure of inclined shafts. It achieves accurate measurement of water level height within the inclined shaft through mechanical adaptation design, attitude compensation algorithm, and signal detection technology.

[0003] Existing ground borehole water level measurement devices generally consist of a probe, a signal transmission line, and a signal receiver. When in use, the probe is placed into the borehole. After the probe contacts the water surface in the borehole and forms a short circuit, the ground signal receiver sends an alarm signal and measures the borehole water level height based on the length of the signal transmission line placed in the borehole. However, in actual use, if the borehole has a large inclination angle, the probe will be affected by gravity when it is lowered. During the lowering process, the probe will often come into contact with the borehole wall. Since the borehole wall is damp and has a high humidity, the damp gas or liquid may transmit incorrect signals after contacting the probe, which may cause the ground signal receiver to misread the data and seriously affect the accuracy of water level measurement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a precise water level measurement device for inclined wells on the ground. This device solves the problem that, in actual use, if the borehole has a large inclination angle, the probe rod is affected by gravity and often comes into contact with the borehole wall during the lowering process. Because the borehole wall is damp and has high humidity, the humid gas or liquid may transmit incorrect signals after contacting the probe rod, causing the ground signal receiver to misread the data and seriously affecting the accuracy of water level measurement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise water level measurement device for inclined wells on the ground, comprising an alarm, wherein the input end of the alarm is electrically connected to a probe rod via a wire, a protective mechanism is provided on the outer wall of the probe rod, and a blocking mechanism is provided below the probe rod; the protective mechanism comprises an upper cylinder, a lower cylinder, an insulating cylinder, and a sealing cap; the inner wall of the upper cylinder is engaged with the outer wall of the probe rod, the outer wall of the upper cylinder is threadedly connected to the lower cylinder, the outer wall of the lower cylinder is fitted with an insulating cylinder, the inner wall of the insulating cylinder is threadedly connected to the outer wall of the upper cylinder, and a sealing cap is fitted to the top of the insulating cylinder, the inner wall of the sealing cap being threadedly connected to the outer wall of the upper cylinder.

[0015] 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.

[0016] In actual use, if the borehole has a large inclination angle, the probe will be affected by gravity when it is lowered. During the lowering process, the probe will often come into contact with the borehole wall. Since the borehole wall is damp and has a high humidity, the moisture or well water may transmit incorrect signals after coming into contact with the probe, which may cause the ground signal receiver to misread the signal and seriously affect the accuracy of water level measurement.

[0017] In view of this, the present invention provides a precise water level measurement device for inclined wells on the ground. This device, through the cooperation of an upper cylinder, a lower cylinder, an insulating cylinder, and a sealing cover, protects the probe rod and effectively prevents humid gas or liquid inside the borehole wall from contacting the probe rod, thus avoiding the phenomenon of "false alarms and false water levels" during water level measurement. It not only ensures the accuracy of water level measurement but also greatly improves the efficiency of water level monitoring.

The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Example 1, by Figure 1-4It is known that a precise water level measurement device for inclined wells on the ground includes an alarm 1. The input end of the alarm 1 is electrically connected to a probe 2 via a wire. A protective mechanism is provided on the outer wall of the probe 2, and a blocking mechanism is provided below the probe 2. The protective mechanism includes an upper cylinder 3, a lower cylinder 4, an insulating cylinder 5, and a sealing cover 6. The inner wall of the upper cylinder 3 is snapped onto the outer wall of the probe 2. The outer wall of the upper cylinder 3 is threadedly connected to the lower cylinder 4. The outer wall of the lower cylinder 4 is fitted with an insulating cylinder 5. The inner wall of the insulating cylinder 5 is threadedly connected to the outer wall of the upper cylinder 3. The top of the insulating cylinder 5 is fitted with a sealing cover 6, and the inner wall of the sealing cover 6 is threadedly connected to the outer wall of the upper cylinder 3. In practical implementation, it is worth noting that the model of alarm 1 can be selected according to actual needs, as long as it meets the operational requirements. For example, it can be the TBJ-150 model, which has a display and input / output ports on its surface. One of the output ports is connected to the end of the detector 2 via a wire. The length of the wire can be determined according to actual needs. Similarly, the specific model of detector 2 can also be selected according to actual needs, as long as it meets the operational requirements. For example, it can be the CYB-20S model. Two circular protrusions are fixedly connected to the outer wall of the base of detector 2. The upper cylinder 3 can be made of stainless steel, and its cross-section is 'convex'. The upper cylinder 3 has an external thread on its outer wall and an internal thread on its inner wall. Two parallel annular grooves are machined on the upper inner wall, which engage with protrusions on the outer wall of the probe rod 2 to secure it inside the upper cylinder 3. The lower cylinder 4 is made of the same material and has the same shape as the upper cylinder 3; it is used to hold heavy objects (stones, iron blocks, etc.). The bottom of the insulating cylinder 5 is open, and it can be made of polytetrafluoroethylene. Its inner wall has internal threads that connect with the external threads on the outer wall of the upper cylinder 3, protecting the upper cylinder 3. Its larger diameter also helps prevent drilling. Water from the borehole wall flows into the interior of the upper cylinder 3 to prevent false readings from the probe 2. The sealing cap 6 is made of the same material as the upper cylinder 3, and its top is machined with a circular through hole for the wire to pass through. Its inner wall is machined with internal threads, which can be threaded to the external threads on the outer wall of the upper cylinder 3. In actual use, the assembled detection device is slowly lowered into the inclined well borehole. During lowering, the outer wall of the insulating cylinder 5 can effectively prevent water adhering to the borehole wall or small seepage streams from directly entering the interior of the upper cylinder 3, thereby preventing water adhering to the borehole wall or small seepage streams from contacting the electrodes of the probe 2, thus avoiding electrical misreading caused by moisture on the well wall. When the device continues to be lowered until it contacts the water surface in the well, the electrodes of the probe 2 form a closed circuit through the water. The electrical signal generated by the electrode conduction is transmitted in real time to the alarm 1 on the ground through the wire. After receiving the continuous conduction signal, the internal circuit of the alarm 1 is triggered. Through the sound and light alarm or the change of the value on its display, it can indicate the moment when the device contacts the water surface in real time and accurately obtain the distance from the water surface to the well opening, thereby calculating the water level depth. This not only improves the accuracy of water level measurement, but also effectively avoids the phenomenon of "false alarm and false water level" in the process of water level measurement. Furthermore, the barrier mechanism includes a spacer seat 7, a flow port 8, and a protective net 9; the outer wall of the spacer seat 7 is engaged with the inner wall of the lower cylinder 4, the outer wall of the spacer seat 7 is attached to the inner wall of the upper cylinder 3, the surface of the spacer seat 7 is provided with a flow port 8, and the inner wall of the flow port 8 is fixedly connected with a protective net 9. In the specific implementation process, it is worth noting that the spacer seat 7 has a 'T' shaped cross section and is made of the same material as the lower cylinder 4. An annular protrusion is machined on the lower part of its outer wall, which can be snapped and fixed with the annular groove on the inner wall of the lower cylinder 4. A circular flow port 8 is opened on its surface, and a protective net 9 is fixed on the inner wall of the flow port 8. The protective net 9 is an 80-100 mesh stainless steel mesh, which can prevent the counterweight inside the lower cylinder 4 from accidentally entering the upper cylinder 3 and causing accidental damage to the probe 2, but will not obstruct the water flow, thus protecting the probe 2. When the protective net 9 is blocked or damaged, the staff can rotate the lower cylinder 4 clockwise to remove it from the bottom of the upper cylinder 3 and remove the spacer seat 7 for replacement or maintenance. Then, the above actions can be repeated in reverse to restore each structure to its initial position, thereby improving the service life of the probe 2. Furthermore, the outer wall of the upper cylinder 3 is provided with a drainage hole 10; In the specific implementation process, it is worth noting that the drainage hole 10 is opened on the upper outer wall of the upper cylinder 3. There are multiple drainage holes 10, and the specific number and size can be set according to actual needs. When the detection position is reached, the water inside the inclined well will enter the interior of the upper cylinder 3 through the drainage hole 10, thereby contacting the probe 2. The probe 2 transmits the water level information to the external alarm 1 through the wire. The staff can accurately and clearly understand the water level information of the inclined well by observing the alarm 1. Example 2, by Figure 1-4 It can be seen that the outer wall of the lower cylinder 4 is provided with a drain hole 11; In the specific implementation process, it is worth noting that the drain hole 11 starts from the outer wall of the lower cylinder 4 and there are multiple drain holes. The specific number and size can be set according to actual needs. When the device is pulled upward after the test is completed, the water inside the upper cylinder 3 will enter the interior of the lower cylinder 4 through the flow port 8 and be discharged from the drain hole 11. This prevents well water from accumulating inside the device and increasing the weight of the device, making it easier and less strenuous for workers to take the device out of the inclined shaft. Furthermore, a sealing seat 12 is attached to the top of the upper cylinder 3, the inner wall of the sealing seat 12 is attached to the outer wall of the probe 2, and the top of the sealing seat 12 is fixedly connected to the inner wall of the sealing cover 6. In the specific implementation process, it is worth noting that the sealing seat 12 is annular and its material can be fluororubber. Its inner wall is convex, so that when the probe 2 is inserted into the inner wall of the sealing seat 12, it fits tightly and achieves a seal, thereby effectively preventing well water from entering the device from the top of the device and avoiding false detection by the probe 2, thus improving the detection accuracy. Furthermore, a sealing ring 13 is provided below the sealing seat 12. The inner wall of the sealing ring 13 is sleeved on the outer wall of the probe rod 2, and the outer wall of the sealing ring 13 is fixedly connected to the inner wall of the upper cylinder 3. In the specific implementation process, it is worth noting that the sealing ring 13 is fixed on the inner wall of the upper cylinder 3. Its inner wall is convex and its material is the same as that of the sealing seat 12. When the probe 2 is working, it prevents the well water inside the upper cylinder 3 from entering the connection between the probe 2 and the upper cylinder 3, thereby ensuring the connection stability between the probe 2 and the upper cylinder 3 and further improving the service life of the device. 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.
