Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically a vehicle-mounted methane power-off device. Background Technology

[0002] The vehicle-mounted methane power cut-off device is an essential methane detection, alarm, and power-off device for explosion-proof special battery locomotives in coal mines. It consists of a mine-use explosion-proof and intrinsically safe vehicle-mounted methane power cut-off device main unit and a mine-use methane sensor, among other equipment. The methane power cut-off device can detect the nearby gas concentration value. When the gas concentration value reaches or exceeds the power-off threshold, the methane power cut-off device can cut off the locomotive's power supply.

[0003] Chinese patent provides a vehicle-mounted methane power-off device main unit, publication number CN217823421U, which includes a main unit housing, a sensor and a circuit board installed inside the main unit housing, and an integrated wiring compartment on the top of the main unit housing, with a wiring cavity cover plate fixedly installed on the top of the wiring compartment by screws.

[0004] The aforementioned power-off device main unit separates the wiring position from the main unit housing by setting a wiring compartment on the main unit housing, which serves as a transition, thereby improving the sealing and structural strength of the wiring position. By setting a power connection mechanism in the wiring compartment, the stability and sealing of the connection mechanism to the main unit housing are high, thereby improving the reliability of the product.

[0005] However, for ease of operation, the power cut-off device is usually installed inside the vehicle and connected to the vehicle's power supply. In this case, the air circulation inside the vehicle is slow, which reduces the efficiency of real-time detection of the external environment. Furthermore, the power cut-off device can only trigger an alarm and cut off the power when the methane concentration inside the vehicle is too high, making it difficult to detect the area around the vehicle and affecting the detection effect of the methane power cut-off device.

Inside the main unit housing, a power module, a signal processing module, and an audible and visual alarm module are arranged on one side. A mounting bracket is installed on the side of the main unit housing away from the power module. A partition is fixedly installed at the center of the top of the mounting bracket. Methane sensor bodies are installed inside the mounting bracket and on both sides of the partition.

[0009] An air inlet is provided at both the front and rear ends of one side of the main unit housing, and an air inlet pipe 1 and an air inlet pipe 2 are respectively connected to the air inlet. The end of the air inlet pipe 2 away from the main unit housing is connected to a split pipe. The end of the split pipe away from the air inlet pipe 2 is connected to several extension pipes. The end of the extension pipe away from the main unit housing is connected to an air inlet head.

[0013] Preferably, an air intake fan is installed inside the main unit housing and in each of the two exhaust ports, and an air duct is provided on the inner side of the main unit housing to be compatible with the air intake fan.

[0014] Preferably, an exhaust port that is compatible with the air intake fan is provided at the lower position of the front and rear ends of the main unit housing, and a baffle is provided inside the exhaust port.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, by setting up an air intake head, a split pipe, an explosion-proof solenoid valve, and a methane sensor body to work together, and by installing the air intake head around the vehicle and intermittently opening the explosion-proof solenoid valve, can monitor the methane content at multiple points around the vehicle, making it easier to obtain methane concentration information at different locations around the vehicle and improving the detection effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Combination Figures 1-3 A vehicle-mounted methane power-off device includes a main unit housing 1. Inside the main unit housing 1, a power module 2, a signal processing module 3, and an audible and visual alarm module are arranged on one side. Inside the main unit housing 1, a mounting bracket 4 is installed on the side away from the power module 2. A partition 5 is fixedly installed at the center of the top of the mounting bracket 4. Methane sensor bodies 6 are installed inside the mounting bracket 4 and on both sides of the partition 5.

[0024] See Figure 2 and Figure 3 Furthermore, it is found that air inlets are provided at both the front and rear ends of one side of the main unit housing 1, and air inlets are respectively connected to air inlets 7 and 8. The end of air inlet 8 away from the main unit housing 1 is connected to a diverter pipe 10. The end of diverter pipe 10 away from air inlet pipe 8 is connected to several extension pipes 11. The end of extension pipe 11 away from the main unit housing 1 is connected to an air inlet head 13. The end of air inlet head 13 away from the extension pipe 11 is equipped with a dust cover 14 by mounting bolts 15. The dust cover 14 is semi-circular. The outer ring of air inlet head 13 is provided with several fixing plates 16. The fixing plates 16 are "L" shaped and are equidistantly arranged on air inlet head 13. Mounting holes are provided on both sides and the top and bottom ends of the fixing plates 16. The extension pipe 11 is a flexible hose, and an explosion-proof solenoid valve 12 is provided at the connection between the extension pipe 11 and the diverter pipe 10.

[0025] Specifically, before use, multiple air intake heads 13 can be installed at suitable positions outside the vehicle as needed, and multiple connecting pipes branching out from the air intake heads 13 at the branch pipes 10 can be connected through the extension pipe 11. During the detection process, the methane concentration at multiple points outside the vehicle can be detected by opening all the explosion-proof solenoid valves 12 or opening different explosion-proof solenoid valves 12 in sequence. This provides high flexibility in use. The monitoring data can be analyzed through the set signal processing module 3. When the methane concentration exceeds the standard, an audible and visual alarm will be triggered to remind the driver to take appropriate measures to prevent the danger from escalating further. At the same time, the circuit breaker can be controlled to cut off the vehicle power supply and prevent sparks caused by vehicle operation from causing a methane explosion. Example 2

[0026] See Figure 2 Furthermore, based on Embodiment 1, an intake fan 9 is installed inside the main unit housing 1 and in both exhaust ports. An air duct adapted to the intake fan 9 is provided on the inner side of the main unit housing 1. An exhaust port adapted to the intake fan 9 is provided at the lower position of the front and rear ends of the main unit housing 1. A baffle is provided inside the exhaust port.

[0027] Specifically, during methane monitoring, an intake fan 9 is used to guide airflow and improve air circulation efficiency. There are two methane sensor bodies 6, which can detect the methane concentration inside and outside the vehicle respectively. The signal processing module 3 can then compare the detection data to improve safety. Furthermore, if a single methane sensor body 6 is damaged, the power failure alarm function will not be completely lost, thus improving fault tolerance.

[0028] In actual operation, multiple air intake heads 13 can be installed at appropriate positions outside the vehicle as needed, and multiple connecting pipes branching out from the air intake heads 13 at the branch pipes 10 can be connected through the extension pipe 11. During the test, the methane concentration at multiple points outside the vehicle can be detected by opening all the explosion-proof solenoid valves 12 or opening different explosion-proof solenoid valves 12 in sequence, which is highly flexible in use.

[0029] Furthermore, the signal processing module 3 can analyze the monitoring data. When the methane concentration exceeds the standard, an audible and visual alarm will be triggered to remind the driver to take appropriate measures to prevent the danger from escalating further. At the same time, the circuit breaker can be controlled to cut off the vehicle's power supply and prevent sparks caused by vehicle operation from causing a methane explosion.

[0030] During methane monitoring, an intake fan 9 is used to guide airflow and improve air circulation efficiency. There are two methane sensor bodies 6, which can detect the methane concentration inside and outside the vehicle respectively. The signal processing module 3 can then compare the detection data to improve safety. Furthermore, if a single methane sensor body 6 is damaged, the power failure alarm function will not be completely lost, thus improving fault tolerance.

[0031] Furthermore, the control components and modules used in the aforementioned intake fan 9, explosion-proof solenoid valve 12, methane sensor body 6, and signal processing module 3 are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
