[0032] As shown in Figure 1 According to the first aspect of the present application, the chain 1, a plurality of first pulleys 2, a first conductive wire 4 and a second conductive wire 5 are provided. The plurality of first pulleys 2 are rotatably arranged on the chain 1, and are arranged at intervals along the extension direction of the chain 1. One end of the first conductive wire 4 is connected to the chain 1, and the other end of the first conductive wire 4 is connected to the positive electrode of the power supply. The first conductive wire 4 is provided with an exposed portion adjacent to the chain 1. One end of the second conductive wire 5 is connected to the chain 1, and the other end of the second conductive wire 5 is connected to the negative electrode of the power supply. The second conductive wire 5 is provided with an exposed portion adjacent to the chain 1. It should be noted that the exposed portion of the first conductive wire 4 can be in contact with the chain 1 for conduction, or the exposed portion of the second conductive wire 5 can be in contact with the chain 1 for conduction, but the exposed portion of the first conductive wire 4 and the exposed portion of the second conductive wire 5 cannot be in contact with the chain 1 at the same time.
[0033] According to the utility model embodiment, the sliding chain type water level measuring probe for middle-deep drilling can be lowered into the underground water in the measuring pipe, the first conductive wire 4 and the second conductive wire 5 are in contact with water at the exposed part, so that the first conductive wire 4 and the second conductive wire 5 are conductive, and thus the distance of lowering the probe can be obtained to realize the detection of the water level. The first pulley 2 is installed on the chain 1, the first pulley 2 can slide on the wall of the measuring pipe, and rotates with the chain links of the chain 1 to realize the lowering of the probe. Due to the flexibility of the chain 1, the probe will not stay at the bending part, and can measure the water level after entering the water normally. Due to the rotation of the chain 1 and the sliding design of the first pulley 2, the probe can be stably lowered in the measuring pipe, and the phenomenon of the measuring pipe being blocked and stuck due to the rotation of the drill bit is avoided. In addition, the design of the chain 1 and the first pulley 2 being relatively heavy significantly improves the efficiency of lowering the probe and reduces the complexity of manual operation.
[0034] It can be understood that the utility model embodiment is suitable for measuring various deep underground water levels, especially in coal mine areas. The flexible design and efficient measurement performance can meet the needs in different environments and conditions. The high-strength and corrosion-resistant chain 1 is used as the main structure, and the bearing part in the middle of the chain 1 is specially designed to accommodate the cable of the water level measuring probe (including the first conductive wire 4 and the second conductive wire 5). The first pulley 2 is arranged on both sides of the chain 1 to ensure smooth running of the chain 1 in the measuring pipe, and the chain 1 can be repeatedly used to provide economic benefits.
[0035] Specifically, the chain 1 is a standard bicycle chain 1 (pitch 2.40 mm, width 0.086 mm), the sleeve inside the pin of the chain link is removed, and only the pin is reserved for connecting multiple chain links.
[0036] According to one embodiment of the utility model, a first pulley 2 is arranged in each chain link of the chain 1. In this way, the chain 1 can slide along the inner wall of the measuring pipe at multiple positions. Alternatively, the diameter of the first pulley 2 can be selected according to actual needs, and the size should be similar to the width of the chain 1. For example, the diameter of the first pulley 2 is 1.20 mm.
[0037] According to one embodiment of the utility model, a plurality of first pulleys 2 are arranged alternately on both sides of the chain 1 in the extension direction of the chain 1. In this way, the stress on both sides of the chain 1 is uniform. It can be understood that, since the chain link is made of rigid material, the pulley can be installed asymmetrically to save space and material cost.
[0038] According to one embodiment of the utility model, for middle -deep layer drilling sliding chain formula measure water level probe including second pulley 3, second pulley 3 is installed in the one end of chain 1, and the diameter of second pulley 3 is greater than the diameter of first pulley 2. It can be understood that the second pulley 3 is installed at the end of the chain 1, and the diameter is larger to ensure that it can slide smoothly under the driving of gravity and is not easy to twist. At the same time, the diameter of the second pulley 3 is greater than the width of the chain 1, since the second pulley 3 is located at the front end of the chain 1 in the downward direction, the space through which the second pulley 3 can pass, then the subsequent chain 1 can also pass, reducing the situation that the chain 1 is difficult to break free due to the middle segment being stuck. Exemplarily, the diameter of the second pulley 3 is 1.30mm.
[0039] According to one embodiment of the utility model, the weight of the second pulley 3 is greater than the weight of the first pulley 2. It can be understood that the second pulley 3 has a larger weight to ensure that the probe can slide under the driving of its own weight, and to ensure that the second pulley 3 is always below the first pulley 2 under the action of gravity, avoiding the folding of the chain 1.
[0040] According to one embodiment of the utility model, one end of the second conductive wire 5 is connected to one end of the chain 1 away from the second pulley 3. It can be understood that one of the first conductive wire 4 and the second conductive wire 5 needs to be connected with the chain 1 in an insulating manner, so that the first conductive wire 4 and the second conductive wire 5 are not conducted through the chain 1, that is, the first conductive wire 4 and the second conductive wire 5 are only conducted through the exposed parts at the same time immersed in water.
[0041] According to one embodiment of the utility model, one end of the first conductive wire 4 is connected to the hollow position of the chain 1. It can be understood that the first conductive wire 4 is fixed to the hollow part in the middle of the chain link, and only the exposed part of the first conductive wire 4 is provided to ensure smooth conduction after entering the water, and the remaining parts are sealed with insulating tape.
[0042] According to one embodiment of the utility model, the material of the chain 1 is steel material, and optionally, the material of the first pulley 2 is steel material. In this way, the overall strength is ensured.
[0043] According to one embodiment of the utility model, the first conductive wire 4 and the second conductive wire 5 can be fixed and waterproofed by the waterproof tape 6. Optionally, the first conductive wire 4 and the second conductive wire 5 are separated adjacent to the exposed parts, so as to avoid the exposed parts of the two being in contact during the lowering process of the probe, which causes water level detection error. Therefore, the distance between the points where the first conductive wire 4 and the second conductive wire 5 are connected to the chain 1 can be set, so as to avoid the exposed parts of the first conductive wire 4 and the second conductive wire 5 being in contact.
[0044] The water level measuring device according to the second aspect of the present application comprises a device body and the above-mentioned sliding chain type water level measuring probe for medium-deep layer drilling.
[0045] The water level measuring device according to the second aspect of the present application comprises a device body and the above-mentioned sliding chain type water level measuring probe for medium-deep layer drilling.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
