[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] This application provides an electromagnetic wave measuring instrument suitable for detecting water curtain caves, which solves the problem that water and other impurities can easily enter the measuring instrument's cylinder when it is used on water drilling rigs in caves. This makes the electromagnetic wave measuring instrument more suitable for engineering construction of water curtain caves.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Example:

[0041] like Figure 1-4 As shown, an electromagnetic wave measuring instrument suitable for detecting water curtain caverns includes a sleeve 1, a cap 2, and a cylinder 3;

[0042] The cap 2 is installed on the sleeve 1, so that the inner cavity of the sleeve 1 forms a closed space of a sealed cylinder 3;

[0043] A cavity 4 is formed between the cylinder 3 and the sealed space, which allows the heat generated by the cylinder 3 to be dispersed and flow.

[0044] The cylinder 3 is the main body of the electromagnetic wave measuring instrument, which integrates an electromagnetic wave target measurement module and emits electromagnetic waves through the electromagnetic wave transmitter for detection. The main body of the electromagnetic wave measuring instrument is based on existing technology, and its structure and principle will not be described in detail here.

[0045] The end of the cap 2 with the protrusion 20 is embedded in the sleeve 1;

[0046] A sealing gasket 21 is also fitted onto the protrusion 20;

[0047] When the cap 2 and the sleeve 1 are closed, the sealing gasket 21 fills the gap between the cap 2 and the sleeve 1, improving the sealing performance when the cap 2 and the sleeve 1 are closed.

[0048] The sleeve 1 has a positioning groove 12 and the protrusion 20 has a positioning groove 201. The positioning groove 12 communicates with the cavity 4 and forms a positioning cavity with the positioning groove 201 for positioning the cylinder 3, which improves the stability of the cylinder 3 installed in the sleeve 1 and facilitates the cylinder 3 to emit electromagnetic waves for detection.

[0049] By setting up sleeve 1 and cap 2, the closed space formed by sleeve 1 and cap 2 is used to protect the cylinder 3. This not only has a waterproof effect, but also prevents impurities from entering the sleeve 1 and affecting the accuracy of the measurement results of the electromagnetic wave target ranging module. This solves the problem that water and other impurities can easily enter the cylinder 3 of the measuring instrument when the electromagnetic wave measuring instrument is applied to the water drilling rig in the cave. This makes the electromagnetic wave measuring instrument more suitable for the engineering construction of water curtain caves.

[0050] Furthermore, when setting up the sleeve 1 and the cap 2, the positioning cavity is formed by the positioning groove 12 on the sleeve 1 and the positioning groove 201 on the cap 2 to position the cylinder 3 placed inside the sleeve 1, ensuring the stability of the cylinder 3 installed inside the sleeve 1, thereby enhancing the accuracy of the electromagnetic waves emitted by the transmitting end of the cylinder 3 for detection.

[0051] It should be noted that the protrusion 20 is part of the cap 2 and is integrally formed with the cap 2.

[0052] Specifically, a sealing ring 202 is embedded in the positioning groove 201 to enhance the sealing between the part of the cylinder 3 located in the positioning groove 201 and the cap 2.

[0053] like Figure 1 As shown, the sleeve 1 has multiple mounting holes 10;

[0054] The cap 2 is provided with a plurality of mounting holes 203 that are adapted to mounting holes 10-1;

[0055] During installation, bolts are passed through the corresponding mounting holes 10 and 203, and nuts are used to secure them, thus achieving a detachable connection between the cap 2 and the sleeve 1.

[0056] Specifically, when setting up sleeve 1 and cap 2, the cross-sections of sleeve 1 and cap 2 are both set to horseshoe shape, which facilitates the overall placement and installation of the electromagnetic wave measuring instrument.

[0057] like Figure 1 As shown, a heat sink 30 is installed at the emitter end of the cylinder 3 to dissipate heat from the cylinder 3.

[0058] Specifically, the heat sink 30 is detachably connected to the cylinder 3 and is installed using bolts or other detachable methods.

[0059] like Figure 1 as well as Figures 3-5 As shown, the outer side of the sleeve 1 is provided with a positioning ring 11 corresponding to the mounting hole 10;

[0060] The outer side of the cap 2 is provided with a positioning ring 22 that corresponds to the mounting hole 203;

[0061] Both the positioning ring 11 and the positioning ring 22 are equipped with sealing ring 221;

[0062] The sealing ring 221 has an L-shaped cross-section, and the folded part covers the outer surface of the positioning ring 11 or the positioning ring 22.

[0063] By setting positioning ring 11 and positioning ring 22, the sealing ring 221 is positioned by positioning ring 11 and positioning ring 22, which prevents the sealing ring 221 from shifting during the tightening of the nut, improves the stability of the bolt and nut installation, and makes the sleeve 1 and the cap 2 achieve a better sealing effect as a whole; at the same time, it can effectively prevent the sealing ring 221 used during the disassembly of the cap 2 and the sleeve 1 from being easily lost.

[0064] It should be noted that when designing the sleeve 1 and the cap 2, the selected materials are non-metallic insulating materials, specifically: plastic, ordinary glass, wood, ceramic (non-magnetic) or rubber. By limiting the thickness of the sleeve 1 and the cap 2, while protecting the cylinder 3 of the electrical wave measuring instrument, the interference of the sleeve 1 and the cap 2 on electromagnetic waves is negligible and will not affect the accuracy of electromagnetic wave measurement.

[0065] Alternatively, the material and thickness can be limited only along the path of electromagnetic waves emitted by the cylinder 3. Specifically, the material and thickness can be limited only for the electromagnetic wave penetration part in the middle of the sleeve 1.

[0066] When in use, the electromagnetic wave measuring instrument described in this application is applied in a cave environment. A quick-connect coupling can be installed at the bottom of the sleeve 1, and the electromagnetic wave measuring instrument can be installed and fixed on the probe bracket for use through the quick-connect coupling.

[0067] The drill bit platform of the drilling rig moves forward, thereby causing the electromagnetic wave target required by the electromagnetic wave measuring instrument to move by different distances in order to detect the drilling depth of the drill pipe;

[0068] When the electromagnetic wave targeting probe of cylinder 3 emits electromagnetic waves forward, it will generate a strong feedback when it encounters the receiver electromagnetic wave target. The data is then processed by the data processing system to obtain the detection data and complete the engineering construction of the water curtain cavern. The electromagnetic wave measurement principle is existing technology and will not be elaborated here.

[0069] In summary, compared with existing technologies, it has the following beneficial effects:

[0070] 1. By setting up sleeve 1 and cap 2, the closed space formed by sleeve 1 and cap 2 protects the cylinder 3. This not only provides waterproofing but also prevents impurities from entering sleeve 1 and affecting the accuracy of the electromagnetic wave target ranging module's measurement results. This solves the problem that water and other impurities can easily enter the measuring instrument's cylinder 3 when the electromagnetic wave measuring instrument is used in cave drilling rigs. This makes the electromagnetic wave measuring instrument more suitable for engineering construction of water curtain caves.

[0071] 2. When setting up the sleeve 1 and the cap 2, the positioning cavity is formed by the positioning groove 12 on the sleeve 1 and the positioning groove 201 on the cap 2 to position the cylinder 3 placed in the sleeve 1, ensuring the stability of the cylinder 3 installed in the sleeve 1, thereby enhancing the accuracy of the electromagnetic waves emitted by the transmitting end of the cylinder 3 for detection.

[0072] 3. By setting positioning ring 11 and positioning ring 22, the sealing ring 221 is positioned by positioning ring 11 and positioning ring 22, which prevents the sealing ring 221 from shifting during the tightening of the nut, improves the stability of the bolt and nut installation, and makes the sleeve 1 and the cap 2 achieve a better sealing effect as a whole; at the same time, it can effectively prevent the sealing ring 221 used during the disassembly of cap 2 and sleeve 1 from being easily lost.
