Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of swamp detection equipment, in particular to a sealed swamp detector. Background Art
[0002] A geophone is a device used to identify the presence or change of waves, oscillations or signals. By identifying the presence or change of waves, oscillations or signals, the detection object is detected. It is widely used in geological surveys and explorations, such as goafs in low-lying geotechnical engineering, geological structure stratum exploration, oil and gas exploration, site detection and evaluation, etc. In the process of field geophysical exploration, swamps and shoals are common areas of use. The main equipment of existing swamp geophones includes geophone movement, outer casing and lead-out cable. Since there is a large amount of liquid water on the surface and underground in swamps and shoals, and swamps belong to a wet environment, the biomass is large, and the organisms are easy to rot and deteriorate. The terrain is low, and a large amount of animal and plant remains are easily deposited, resulting in a high content of organic acid and iron and manganese in the water body. Compared with other environments, when used in a swamp environment, the sealing ring of the geophone is more likely to be corroded and deformed and cause failure. The current geophone does not have any sealing ring failure warning structure. Putting it into use in a failed state will cause water damage to the movement, affecting the safety and service life of the movement. Utility Model Content

[0031] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.
[0032] Combination Figure 1-Figure 4 The swamp detector of the embodiment shown is intended to improve the airtight and watertight performance of the detector, so that the detector can prevent water vapor from intruding when used in a swamp, and can also be used in an emergency in the event of a seal failure. According to the above purpose, the swamp detector proposed by the utility model includes an outer protective shell 1, a sealing cover 2, a detector movement 3 and a cone head 4.
[0033] The outer protective shell 1 is configured as a cylindrical shell with an opening at one end, the sealing cover 2 is connected to the open end of the outer protective shell 1 to seal the inner cavity of the outer protective shell 1, the detector movement 3 is arranged inside the outer protective shell 1 and connected to the sealing cover 2 to facilitate the disassembly of the detector movement 3;
[0034] A connecting line 31 for connecting the detector movement 3 and external equipment and transmitting signals is led out from the center of the sealing cover 2. A sealing sleeve 32 for sealing is provided between the connecting line 31 and the sealing cover 2 to avoid leakage in the gap between the connecting line 31 and the sealing cover 2.
[0035] In an optional embodiment, one end of the sealing sleeve 32 extends along the connecting line 31 to the outside of the sealing cover 2 and is wrapped around the connecting line 31. The sealing sleeve 32 is made of rubber material. The sealing sleeve 32 can protect the part of the connecting line 31 that is led out to prevent the connecting line 31 from being bent and damaged.
[0036] Furthermore, a cone head 4 is connected to the bottom of the outer casing 1 to guide the detector to be inserted into the ground.
[0037] In a specific embodiment, a plurality of support plates 6 with holes are provided around the edge of the sealing cover 2, and a plurality of connecting blocks 7 with threaded holes are provided around the top of the outer protective shell 1. Bolts pass through the support plates 6 and are threadedly connected to the connecting blocks 7 on the outer protective shell 1, thereby pressing and fixing the sealing cover 2 on the outer protective shell 1.
[0038] Furthermore, a sealing ring 5 for sealing is provided on the end face of the connection between the outer protective shell 1 and the sealing cover 2. Since the sealing cover 2 and the outer protective shell 1 are connected by bolts, the sealing ring 5 is pressed against the end face of the connection between the outer protective shell 1 and the sealing cover 2 by rotating the bolts to seal the connection.
[0039] When the thread is used to rotate and tighten the sealing ring, friction will be generated with the sealing ring, and excessive pressing force will cause fatigue damage to the sealing ring, resulting in failure of the sealing ring and prone to leakage. Figure 1 , Figure 2 and Figure 3As shown, a pressure sealing portion 51 is provided on the inner side of the sealing ring 5, and the cross section of the pressure sealing portion 51 is set to a V-shaped structure with an opening on one side, so that a cavity 501 is formed on the inner side of the pressure sealing portion 51, and the open end of the pressure sealing portion 51 faces the inner side of the outer protective shell 1, and a first inclined groove 101 is provided on the inner side of the end surface of the connection of the outer protective shell 1, and a second inclined groove 201 is provided on the inner side of the end surface of the connection of the sealing cover 2. When the sealing cover 2 is connected to the outer protective shell 1, the pressure sealing portion 51 is respectively fitted in the first inclined groove 101 and the second inclined groove 201.
[0040] Furthermore, the outer protective shell 1 is provided with a pressurizing component capable of increasing the internal air pressure of the outer protective shell 1 so as to form a high-pressure environment inside the cavity 501 .
[0041] In this way, the air pressure inside the outer protective shell 1 is increased by the pressurizing component, so that the inside of the cavity 501 of the pressure sealing part 51 is in a high-pressure state, the pressure acts on the inner wall of the cavity 501, and the pressure sealing part 51 is pressed against the first skew groove 101 and the second skew groove 201, so that the pressure sealing part 51 is tightly fitted with the first skew groove 101 and the second skew groove 201 to prevent liquid penetration. At the same time, if the sealing ring 5 is corroded and fails, a leakage channel will be formed between the inside of the outer protective shell 1 and the external environment. At this time, under the action of pressure, the gas will be discharged through the leakage channel. When the detector is put into water, bubbles will appear, which will serve as a warning to the operator. At the same time, the discharged gas will make the leakage channel in a positive pressure state to prevent water from entering the inside of the outer protective shell 1.
[0042] Furthermore, a one-way valve 21 capable of communicating with the interior of the outer protective shell 1 is installed on one side of the sealing cover 2. After the sealing cover 2 is connected to the outer protective shell 1 and tightened to seal, an external gas delivery pump can be used to continuously pressurize the interior of the outer protective shell 1 through the one-way valve 21, so that a higher pressure is always maintained inside the outer protective shell 1. There is sufficient gas inside the outer protective shell 1 that can be continuously released, so that the leakage point is always in a positive pressure state, water vapor cannot enter, and the sealing time is extended, so that the detector can be used urgently even if the seal fails and there is no need to replace parts.
[0043] Combination Figure 4 As shown, the pressurizing component includes a pressurizing chamber 103 opened at the bottom of the outer protective shell 1 and a piston 11 sliding in the pressurizing chamber 103. When the piston 11 slides upward, the air in the outer protective shell 1 can be compressed and pressurized. The bottom of the outer protective shell 1 is provided with a mounting hole 102 corresponding to the pressurizing chamber 103 and used for installing the cone head 4. The top of the cone head 4 is provided with a second magnetic block 42, and the bottom of the piston 11 is provided with a first magnetic block 12 with the same pole as the second magnetic block 42. When the cone head 4 is connected to the outer protective shell 1, the second magnetic block 42 is close to the first magnetic block 12, and the repulsive magnetic force pushes the first magnetic block 12 and the piston 11 upward, thereby compressing the air and increasing the internal pressure of the outer protective shell 1.
[0044] In an optional embodiment, the maximum distance at which the second magnetic block 42 and the first magnetic block 12 can generate magnetic repulsion is 5.0-8.0 cm, and preferably the maximum distance at which the magnetic repulsion is 8.0 cm, so that the second magnetic block 42 can use the magnetic repulsion to push the first magnetic block 12 to a farther distance, thereby increasing the internal pressure of the inner cavity of the outer protective shell 1 and the cavity 501, and improving the sealing effect.
[0045] Furthermore, the diameter of the first magnetic block 12 is smaller than the inner diameter of the pressurizing chamber 103, so as to prevent the first magnetic block 12 from contacting the inner wall of the pressurizing chamber 103 when sliding, thereby reducing friction.
[0046] In a preferred embodiment, the first magnetic block 12 and the second magnetic block 42 are both neodymium iron boron magnets, which have strong magnetic force and can push the first magnetic block 12 to a greater distance.
[0047] Furthermore, the mounting hole 102 is a threaded hole, and a screw 41 corresponding to the mounting hole 102 is provided at the top of the cone head 4. The cone head 4 is connected to the outer protective shell 1 through threads, which is convenient for disassembly and assembly of the cone head 4.
[0048] In a specific embodiment, the second magnetic block 42 is installed on the top of the screw rod 41 . As the screw rod 41 is screwed into the mounting hole 102 , the second magnetic block 42 can approach the first magnetic block 12 .
[0049] In combination with the above embodiments, the swamp detector proposed by the utility model is provided with a pressure sealing part 51 with a V-shaped cross-section on the inner side of the sealing ring 5, a cavity 501 is formed on the inner side of the pressure sealing part 51, and a corresponding inclined groove is provided on the inner side of the end face of the connection of the outer protective shell 1, and a pressurizing component is provided on the outer protective shell 1; the pressurizing component is used to make the inside of the cavity 501 of the pressure sealing part 51 in a high-pressure state, and the pressure acts on the inner wall of the cavity 501, and the pressure sealing part 51 is pressed against the corresponding inclined groove to prevent liquid penetration. At the same time, if the sealing ring 5 is corroded and fails, a leakage channel will be formed between the inside of the outer protective shell 1 and the external environment. At this time, under the action of pressure, the gas will be discharged through the leakage channel. When the detector is put into water, bubbles will appear, which will serve as a warning to the operator. At the same time, the discharged gas will make the leakage channel in a positive pressure state to prevent water from entering the inside of the outer protective shell 1.
[0050] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
