Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a carbon monoxide sensor for mining. Background Technology

[0002] Carbon monoxide sensors for coal mines are mainly suitable for underground coal mine applications. They are used in conjunction with fixed methane alarm power-off devices and other power-off devices. They can be used on large and medium-sized mining equipment and other electromechanical equipment in underground mines to continuously monitor the carbon monoxide concentration in the airflow near the equipment. They can also be used in fixed applications. When the carbon monoxide concentration reaches or exceeds the alarm point, the sensor will immediately issue an audible and visual alarm signal to ensure production safety.

[0003] Chinese Patent Publication No. CN207541049U discloses a carbon monoxide sensor for mining, including a housing comprising a front cover and a rear cover. A fixing block is located on the top of the housing, a communication cable interface is located on one side of the fixing block, and a power interface is located on the other side of the communication cable interface. An LED display is located on the front of the front cover, and a buzzer is located at the bottom of the LED display. Sensing elements are arranged around the surface of the housing, and a light alarm lamp is located at the bottom of the housing. A microcontroller is located inside the housing, and the input terminal of the microcontroller is connected to a smart instrument and an A / D converter. This invention enables network connectivity for remote monitoring of carbon monoxide content changes underground, offering high safety. Furthermore, the external light alarm glass cover of the light alarm lamp prevents underground dust from seeping into the gap between the light alarm lamp and the housing, and also prevents dust accumulation on the surface of the light alarm lamp, facilitating dust cleaning.

[0004] Traditional mining carbon monoxide sensors lack a limiting and locking structure, which prevents the sensor head from being effectively limited and locked, causing it to swing during actual use. At the same time, the lack of a corresponding limiting and fixing structure between the sensor transmission connectors makes them prone to shaking, which can affect the wiring safety of the transmission connectors. Utility Model Content

[0005] The main objective of this invention is to provide a mining carbon monoxide sensor that effectively solves the problems mentioned in the background art. Traditional mining carbon monoxide sensors lack a limiting and clamping structure, resulting in the sensor head not being effectively limited and clamped, causing swaying during actual use. Additionally, the lack of a corresponding limiting and fixing structure between the sensor transmission connectors makes the transmission connectors prone to shaking, which affects the wiring safety of the transmission connectors.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A carbon monoxide sensor for mining includes a sensor body, a handle fixedly connected to the top of the sensor body, a buzzer fixedly connected to the center of the front surface of the sensor body, a display screen embedded near the bottom of the front surface of the sensor body, a connecting tube connected to the bottom of the sensor body, a sensing head connected to the bottom end of the connecting tube, a cover plate covering the rear surface of the sensor body, a threaded pin connecting the cover plate and the sensor body, multiple transmission connectors connected to one outer surface of the sensor body, and a limit clamping structure connecting the sensor body and the sensing head.

[0008] As a further embodiment of this utility model, the limiting clamping structure includes a fixed seat, a connecting seat, a connecting rod, and a limiting plate. The fixed seat is fixed to the bottom of the sensor body near both sides. The connecting seat is fixed to the bottom of the fixed seat. The connecting rod passes through the interior of the connecting seat. The limiting plate is fixed to the end of the connecting rod and is clamped on the outer surface of the sensor head.

[0009] As a further embodiment of this utility model, a connecting head is fixedly connected to the top of the limiting plate, the top surface of the connecting head is flush with the bottom surface of the sensor body, a locking head is sleeved on the outer surface of the connecting rod, the locking head is in contact with the connecting seat, and the limiting plate and the connecting rod move synchronously.

[0010] As a further embodiment of this utility model, the connecting rod is fixedly connected to the connecting seat through a locking head, and the connecting head moves synchronously with the limiting plate.

[0011] As a further embodiment of this utility model, a retainer is sleeved on the outer side of the transmission connector, and a fixing frame is fixedly connected to one side of the outer surface of the sensor body, with the fixing frame and the retainer fitting together.

[0012] As a further embodiment of this utility model, a fixing pin is inserted inside the fixing frame, and a fixing hole adapted to the fixing pin is opened inside the retainer.

[0013] The beneficial effects of this utility model are as follows: by setting a limiting and clamping structure, the sensing head of the sensor can be limited and clamped, which can prevent the sensing head from swinging and improve the safety of the sensor head in use.

[0014] By setting a retainer, a fixing bracket, a fixing pin box, and fixing holes, the sensor's transmission connectors can be limited and fixed, preventing the transmission connectors from shaking. Attached Figure Description

The fixed base 11 is fixed to the bottom of the sensor body 1 near both sides. The connecting base 12 is fixed to the bottom of the fixed base 11. The connecting rod 13 passes through the interior of the connecting base 12. The limiting plate 14 is fixed to the end of the connecting rod 13 and is clamped on the outer surface of the sensing head 6.

[0023] Specifically, pushing the connecting rod 13 causes the limiting plate 14 to lock onto the outside of the sensor head 6, thus limiting and locking the sensor head 6 and preventing it from swinging.

[0024] See Figure 3 Furthermore, the top of the limiting plate 14 is fixedly connected to the connector 15, the top surface of the connector 15 is flush with the bottom surface of the sensor body 1, the outer surface of the connecting rod 13 is fitted with a locking head 16, the locking head 16 is in contact with the connecting seat 12, the limiting plate 14 and the connecting rod 13 move synchronously, the connecting rod 13 is fixedly connected to the connecting seat 12 through the locking head 16, and the connector 15 and the limiting plate 14 move synchronously.

[0025] Specifically, when the limiting plate 14 reaches the appropriate limiting clamping position, the connecting rod 13 is fixed to the connecting seat 12 through the locking head 16, which can achieve relative fixation of the limiting clamping structure 10. Example 2
