Description

Technical Field

[0001] The invention relates to the technical field of coal mine seismic wave detection, and in particular to a node-type seismic collector casing. Background Art

[0002] In the field of coal mine seismic exploration, seismic collectors are key equipment, and their stability and reliability directly affect the quality and efficiency of seismic data collection. Especially in harsh environments such as underground coal mines, seismic collectors need to face multiple challenges such as high humidity, high dust, large temperature changes, and potential mechanical shocks. Therefore, it is particularly important to design a casing that can effectively protect the electronic components inside the seismic collector from these harsh environments.

[0003] Most of the existing seismic collector housings adopt the traditional split structure, that is, the housing part and the cover part are connected by bolts or buckles. Although this structure is simple, it has shortcomings in terms of sealing and durability. Especially in complex environments such as underground coal mines, the split structure is prone to loose connections due to vibration or impact, which in turn affects the sealing performance of the housing, making the internal electronic components susceptible to erosion by pollutants such as dust and moisture, resulting in an increase in equipment failure rate and a shortened service life.

[0004] In addition, the existing seismic collector housing also has deficiencies in battery installation and charging interface design. If the battery is not firmly installed or the charging interface is poorly sealed, it may cause problems such as loose batteries, poor contact, or water ingress into the charging interface, which in turn affects the normal use and safety of the device. Summary of the invention

[0005] The purpose of the present invention is to propose a node-type seismic collector casing, which can improve the sealing and durability of the casing and achieve more effective protection for the electronic components inside the seismic collector.

[0006] To achieve the above-mentioned purpose, the embodiment of the present disclosure provides a node-type seismic collector casing, comprising a shell part and a cover part;

[0007] The housing part includes a lower shell, a battery compartment and a glue seal limit plate, and the lower shell and the battery compartment are designed in an integrated manner; a glue seal limit column is also arranged inside the lower shell, and after the battery is installed, the glue seal limit plate of the thin plate structure is placed on the glue seal limit column and fixed by epoxy resin;

[0008] The cover body part includes an upper cover, a sealing ring and a sealing plug; the upper cover is provided with a casing sealing groove and a fastening connection hole; the sealing ring is installed in the casing sealing groove; the fastening connection hole is used to connect with the lower casing, and the upper cover and the lower casing are tightly connected by fastening screws, and a sealing groove is provided in the fastening connection hole, and the sealing groove is used to install a sealing plug to close the fastening connection hole connected to the lower casing.

[0009] Beneficial effects of the basic solution: Through the integrated design of the lower shell and battery compartment structure, the shell components are significantly simplified, the assembly process of the casing is simplified, the processing and manufacturing costs and complexity are reduced, and the structural strength of the entire casing is improved, which is conducive to resisting external shocks such as earthquakes and protecting internal electronic components and batteries from damage.

[0010] After the battery is installed, the thin-plate structure of the glue seal limit plate is placed on the glue seal limit column and fixed by epoxy resin casting to improve the flatness of the battery casting and effectively control the casting thickness to ensure that the sealing effect is optimal, ensure the stability and sealing of the battery installation, improve the waterproof and dustproof level of the casing, ensure that the seismic collector can work stably in harsh environments (such as humid and dusty areas), and extend the service life of the equipment.

[0011] The upper cover and the lower shell are tightly connected by fastening screws, and a sealing groove is arranged in the fastening hole, a sealing plug is installed in the sealing groove, and a sealing ring is arranged in the sealing groove of the casing. This technical solution further enhances the sealing performance of the casing through multiple sealings, effectively prevents the intrusion of external substances such as water and dust, and ensures the cleanliness and stability of the internal environment of the seismic collector.

[0012] At the same time, the sealing groove design in the fastening connection hole makes the installation of the sealing plug more accurate, reduces the error in the assembly process, and ensures the overall sealing of the casing and the neatness of the appearance.

[0013] As an implementable preferred solution, a plug-in limit groove is provided on the side of the lower shell, and a plug-in charging contact is provided inside the plug-in limit groove, and the plug-in charging contact is connected to the battery through a circuit.

[0014] As an implementable preferred solution, the lower shell is also provided with a hook assembly mounting hole and a hook receiving and releasing groove. The hook assembly includes a hook body, a swivel, a connecting pin and a positioning screw.

[0015] As an implementable preferred solution, the hook body adopts a cylindrical bent hook plus a flat transition structure; the connection between the hook and the swivel adopts a double fork structure, which can achieve 180° rotation around the swivel; the swivel is an annular structure with a pin hole in the middle for interference connecting the hook and the swivel with the connecting pin; the positioning screw is used to fix the swivel and the lower shell.

[0016] As an implementable preferred solution, the upper cover is also provided with switch and socket holes for installing a power switch and a socket to achieve switch control of the seismic collector and connection of external equipment.

[0017] As an implementable preferred solution, the upper cover is also provided with a USB hole for installing a USB interface to facilitate data transmission and firmware upgrades.

[0018] As an implementable preferred solution, a USB sealing cover is provided on the outer side of the USB hole to protect the interface from dust and moisture.

The limiting sealing tongue is used to be pressed into the USB hole to form a tight seal for the USB interface; the lifting block facilitates pulling open the USB sealing cover for data transmission or firmware upgrade; the pressure plate groove is used to install the USB sealing cover pressure plate and then install the fastening screws to prevent the fastening screws from directly pressing the rubber USB sealing cover and causing damage. The design size of the pressure plate groove is larger than the size of the USB sealing cover pressure plate to form a gap to facilitate the flipping operation of the USB sealing cover and increase its service life.

[0020] As an implementable preferred solution, the upper cover is also provided with an indicator light installation slot for installing a working status indicator light, which indicates the working status of the seismic collector through lights of different colors.
