Description

Technical Field

[0001] The utility model belongs to the field of node-type seismographs, and in particular relates to a cable-free seismic node instrument. Background Art

[0002] The seismic node instrument in the prior art is also called a node-type seismograph. The node-type seismograph is an instrument used for earthquake monitoring and research. Its principle and application are of great significance in modern seismology. The node-type seismograph collects and transmits seismic wave signals by arranging multiple seismic sensor nodes in the crust, thereby realizing real-time monitoring and analysis of seismic activities. Due to the constraints of the cable connection cable of the cabled seismograph, modern node instruments usually use a cable-free design. The use of GPS high-precision timing synchronization and precise positioning technology can realize the flexible laying of the observation system. The use of wireless communication technology can monitor the working status of the instrument in real time, which is conducive to operations in various complex geographical and geological environments.

[0003] The Chinese patent application number CN202222842654.1 discloses a seismic node instrument, including a main body, a detection needle is installed at the bottom of the main body, a detector and an integrated module are respectively arranged inside the main body, the integrated module is arranged on the upper side of the detector, and the integrated module is electrically connected to the detector, a battery box is fixedly arranged on the upper surface of the main body, a battery slot is opened on the upper surface of the battery box, a rechargeable battery is detachably installed in the battery slot, the rechargeable battery is electrically connected to the integrated module, a protective cover is hinged on the upper surface of the battery box, an antenna is arranged on the side of the upper surface of the protective cover, and a dedicated battery box is arranged on the main body;

[0004] The above technical solution allows the rechargeable battery to be removed and replaced by opening the protective cover on the battery box. When long-term detection is required in the area, the battery life can be guaranteed by simply replacing the rechargeable battery, and there is no need to bring the entire device back to the charging center for charging. However, in actual use, the device has been fixed on the ground. Due to battery replacement, it is necessary to open the protective cover and replace it in a humid location on the ground. When the protective cover is closed after the replacement is completed, a certain amount of moisture may enter the battery slot, and the moisture may corrode the battery, causing rapid aging, reduced capacity, and even the possibility of explosion, posing certain safety hazards.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0019] 2.

DETAILED DESCRIPTION

[0029] The utility model will now be further described in detail with reference to the accompanying drawings.

[0030] See also Figure 1-4 As shown, in this embodiment, a cableless seismic node instrument is provided, including a node instrument body 1, an energy supply block 2 is fixedly connected to the upper side of the node instrument body 1, a battery cavity 3 is opened on the upper side of the energy supply block 2, two backup batteries 301 matching with the node instrument body 1 are installed on the lower side of the inner wall of the battery cavity 3, an energy supply battery 302 matching with the backup battery 301 is installed inside the battery cavity 3, and a closing plate 5 is rotatably matched with the upper side of the energy supply block 2;

[0031] The node instrument body 1 is a wireless node instrument of model WLU-3C. The backup battery 301 is electrically connected to the node instrument body 1, and can power the node instrument body 1. After the energy supply battery 302 is installed in the battery cavity 3, it can be connected to the backup battery 301 to realize common power supply and improve battery life. The principle is the same as the circuit in the comparative document;

[0032] The inner wall of the energy supply block 2 is provided with a moisture absorption cavity 6, and an adsorbent is installed inside the moisture absorption cavity 6. The adsorbent can be a commonly used desiccant. A plurality of air holes 7 are provided on one side of the inner wall of the moisture absorption cavity 6. A sealing plate 8 is slidably fitted on one side of the moisture absorption cavity 6. A trigger rod 9 penetrating to the upper side of the energy supply block 2 is fixedly connected to the upper side of the sealing plate 8. The portion of the trigger rod 9 penetrating the energy supply block 2 is slidably fitted.

[0033] A limiting mechanism 10 is installed on the lower side of the blocking plate 8 , and a reinforcing mechanism 11 is installed on the node instrument body 1 .

[0034] One aspect of the application of this embodiment is: when in use, firstly, the tail vertebra of the node instrument body 1 is inserted into the ground to keep it vertical and coupled with the ground, and the vibration situation underground is transmitted to the node instrument body 1. The node instrument body 1 has a signal transmission function and is connected to the terminal. The test frequency is transmitted to the terminal to form data;

[0035] During the use of the node instrument body 1, the node instrument body 1 is continuously powered by the backup battery 301 and the power supply battery 302 in the power supply block 2. First, the power of the power supply battery 302 is consumed. When the power of the power supply battery 302 is insufficient, the closing plate 5 can be opened, the power supply battery 302 can be disassembled, and then the closing plate 5 can be closed. The power supply body can be continuously replaced without disassembling the node instrument body 1. During the replacement process, the backup battery 301 is used as a backup power supply, which will not cause the node instrument body 1 to detect the terminal and data loss.

[0036] When the closing plate 5 is opened, since the node instrument body 1 is installed on the ground, especially in areas with high humidity, a large amount of humid air may enter the interior of the energy supply block 2 due to its high humidity. When the closing plate 5 is closed, the trigger rod 9 will be squeezed, causing the trigger rod 9 to push the blocking plate 8 downward. The blocking plate 8 is a plate with multiple openings that match the air holes 7. When the closing plate 5 is in the closed state, the openings overlap with the air holes 7, so that the desiccant in the moisture absorption cavity 6 dries the humid gas in the battery cavity 3 through the air holes 7, reducing the possibility of moisture damage to the backup battery 301 and the energy supply battery 302, thereby improving safety.

[0037] When the closing plate 5 is opened, the blocking plate 8 is pushed by the limiting mechanism 10 so that the opening on the blocking plate 8 is offset from the vent hole 7, thereby temporarily sealing the moisture absorption cavity 6 and preventing the desiccant on the inner wall of the moisture absorption cavity 6 from absorbing unnecessary moisture when the closing plate 5 is opened for a long time.

[0038] The limiting mechanism 10 of this embodiment includes two limiting grooves 101 provided on the lower side of the inner wall of the moisture absorption cavity 6, a limiting rod 102 fixedly connected to the lower side of the blocking plate 8 and slidingly matched with the two limiting grooves 101, and two return springs 103 fixedly connected between the blocking plate 8 and the moisture absorption cavity 6 and sleeved on the limiting rod 102;

[0039] When the blocking plate 8 moves up and down, the limiting rod 102 slides in the limiting groove 101 to increase the stability of the blocking plate 8 when moving up and down. When the trigger rod 9 is not squeezed by external force, the elastic force generated by the return spring 103 causes the blocking plate 8 to move upward, so that the opening on it is staggered with the air vent 7, thereby achieving temporary sealing of the air vent 7.

[0040] The reinforcement mechanism 11 of this embodiment includes a reinforcement plate 111 mounted on the node instrument body 1, a conical needle 112 rotatably fitted on the lower side of the reinforcement plate 111, a plurality of expansion rods 113 slidably fitted on the upper side of the reinforcement plate 111, and a lower pressing plate 114 fixedly connected to the upper ends of the plurality of expansion rods 113;

[0041] When installing the node instrument body 1, the reinforcement plate 111 will first move downward along with the tail vertebrae of the node instrument body 1. During the movement, the conical needles 112 have a certain damping effect. Since the lower sides of the conical needles 112 are all in a conical state, they will not open during the downward insertion process. After being inserted into the ground, the reinforcement plate 111 contacts the ground, and pushes the expansion rod 113 in the conical needles 112 by pushing the lower pressure plate 114 downward, so that multiple conical needles 112 are deployed to compact the ground, thereby improving the stability of the installation on the ground after installation, reducing the impact of wind, and improving detection accuracy.

[0042] In this embodiment, a waterproof sealing gasket 12 is fixedly connected to one side of the closing plate 5. The waterproof sealing gasket 12 is made of waterproof rubber and is located between the energy supply block 2 and the closing plate 5. After being squeezed, the connection is sealed. The energy supply block 2 and the closing plate 5 can be connected by bolts, snaps, etc.

[0043] Two operating handles 13 are fixedly connected to the two sides of the energy supply block 2 of this embodiment. The operating handles 13 are convenient for taking, installing or disassembling the energy supply block 2.

[0044] The lower pressure plate 114 of this embodiment is fixedly connected to pedal boards 14 on both sides, and anti-skid grooves 15 are provided on the upper sides of the two pedal boards 14. After the reinforcement plate 111 contacts the ground, the lower pressure plate 114 can be operated by stepping on the pedal boards 14. The anti-skid grooves 15 increase the friction between the sole of the foot and the pedal boards 14, thereby improving the convenience of operating the lower pressure plate 114.

[0045] A feeding port 16 is provided on the other side of the inner wall of the moisture absorption cavity 6 of this embodiment, and a sealing plate 17 matching the feeding port 16 is installed on one side of the energy supply block 2. The sealing plate 17 facilitates sealing of the feeding port 16. The feeding port 16 is used to feed desiccant, moisture absorbent, etc. into the moisture absorption cavity 6.

[0046] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
