Description

Technical Field

[0001] This invention belongs to the field of coal mine safety monitoring technology, and particularly relates to a monitoring calibration interlocking device. Background Technology

[0002] The main component of coal mine gas is methane. As a flammable and explosive gas, methane is widely present in geological coal seams and poses a hidden danger to coal mining accidents. Detecting the concentration of methane gas in the mine is crucial to avoiding accidents, and the methane sensor needs to be calibrated before concentration detection. Existing standard gas cylinders for methane sensors can be easily opened on-site for standard gas sample calibration. However, if operators forget to put the methane sensor into calibration mode before opening the cylinder, it will trigger the uploading of actual gas exceedance data, which has a very negative impact on the normal and stable production of the enterprise. Based on this, a monitoring calibration interlock device, namely a methane sensor cylinder interlock device, has been invented. Opening the cylinder requires forcibly triggering the calibration key to put the methane sensor into calibration mode, fundamentally eliminating the hidden danger of false gas alarms and contributing to stable production. Summary of the Invention

[0003] The purpose of this invention is to provide a computer vision inspection device to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A monitoring and calibration interlocking device includes: an interlocking box and a box cover rotatably connected to the back of the interlocking box, wherein a gas cylinder is provided inside the interlocking box and the gas outlet of the gas cylinder passes through the side wall of the interlocking box.

[0006] A storage frame with an upward-facing opening is provided on one side wall of the box lid. A remote control is placed inside the storage frame. A pin hole is provided on the side of the storage frame opposite to the box lid. A first pin sleeve 8 is provided on the lower front of the box lid, close to the storage frame. A second pin sleeve is provided on the upper front of the locking box, away from the storage frame. A pin shaft corresponding to the pin hole is inserted inside the first pin sleeve 8 and the second pin sleeve. When one end of the pin shaft is inside the second pin sleeve, the other end is inside the first pin sleeve 8. When one end of the pin shaft is detached from the second pin sleeve, the other end passes through the pin hole and contacts the calibration button on the remote control.

[0007] As a further improvement of the present invention, the pin shaft is provided with a push shaft parallel to its axis.

[0008] As a further improvement of the present invention, the pin sleeve 8 includes a sleeve part, a limiting part and a guide part connected in sequence, the sleeve part being close to the storage frame; the middle part of the limiting part is a plane, and the middle part of the guide part is provided with a slot for accommodating the passage of the push shaft.

[0009] As a further improvement of the present invention, it also includes a gas tube and a methane sensor, wherein the two ends of the gas tube are respectively connected to the methane sensor and the gas outlet of the gas cylinder.

[0010] As a further improvement of the present invention, the storage frame is welded to the box lid.

[0011] As a further improvement of the present invention, the first pin sleeve 8 is connected to the box cover, and the second pin sleeve is connected to the locking box by bolts or welding.

[0012] As a further improvement of the present invention, the back of the locking box and the box cover are rotatably connected by a hinge.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] The invention provides a locking box and a box cover equipped with a first pin sleeve 8, a second pin sleeve, and a remote control. When the box is opened, the pin shaft will first touch the calibration button on the remote control, causing the methane sensor to enter the calibration mode. This effectively solves the problem of data discrepancies caused by professionals forgetting to operate the methane sensor into the calibration mode, essentially solving the problem of false alarm data during calibration and reducing the negative impact on enterprise safety production.

[0023] To better understand the purpose, structure, and function of this invention, a clear and complete description of the invention is provided below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] like Figures 1-5 The monitoring calibration interlocking device shown includes: an interlocking box 1 and a box cover 2 rotatably connected to the back of the interlocking box 1. A gas cylinder 3 is housed inside the interlocking box 1, and the gas cylinder 3's outlet 4 passes through the side wall of the interlocking box 1. The gas cylinder 3 is used to connect to a methane sensor 13 to complete the calibration operation. The interlocking box 1 and the box cover 2 are rotatably connected, facilitating the opening of the box cover 2 to expose the gas cylinder 3 and open its valve. In this embodiment, the back of the interlocking box 1 and the box cover 2 are rotatably connected by a hinge 15.

[0026] A storage frame 5 with an upward-facing opening is provided on one side wall of the box cover 2. A remote control 6 is provided inside the storage frame 5. The thickness of the remote control 6 is less than the internal thickness of the storage frame 5. A pin hole 7 is provided on the side of the storage frame 5 opposite to the box cover 2. The pin hole 7 is opposite to the calibration key on the remote control 6. In this embodiment, the storage frame 5 and the box cover 2 are welded together. A first pin sleeve 8 is provided on the lower front of the box cover 2. The first pin sleeve 8 is close to the storage frame 5 and corresponds to the pin hole 7. A second pin sleeve 9 is provided on the upper front of the locking box 1. The second pin sleeve 9 is away from the storage frame 5 and corresponds to the first pin sleeve 8. The first pin sleeve 8 and the box cover 2, and the second pin sleeve 9 and the locking box 1 are connected or welded by bolts 14.

[0027] Furthermore, a pin shaft 10 corresponding to the pin hole 7 is inserted inside both the first pin sleeve 8 and the second pin sleeve 9. When one end of the pin shaft 10 is inside the second pin sleeve 9, the other end is inside the first pin sleeve 8. When one end of the pin shaft 10 is detached from the second pin sleeve 9, the other end passes through the pin hole 7 and contacts the calibration key on the remote control 6. In addition, to facilitate pushing the pin shaft 10, a push shaft 11 parallel to its axis is provided on the pin shaft 10. When moving the pin shaft 10, the push shaft 11 only needs to be pushed along the axial direction of the pin shaft 10. Further, the first pin sleeve 8 includes a sleeve portion 81, a limiting portion 82, and a guide portion 83 connected in sequence. The sleeve portion 81 is close to the storage frame 5. The middle of the limiting portion 82 is flat, and the middle of the guide portion 83 has a slot 84 for accommodating the push shaft 11.

[0028] The specific usage process is as follows:

[0029] by Figure 1 With the direction as a reference, when the locking box 1 and the box cover 2 are locked, the right end of the pin shaft 10 is located inside the pin sleeve 9. At this time, the left end of the push rod is tangent to the right end of the guide part 83, and the axis of the push rod forms a certain angle with the horizontal plane to prevent the push rod from passing through the slot 84; the left end of the pin shaft 10 is located inside the pin sleeve 8, and the distance from its left end to the remote control 6 is equal to the distance from the right end of the pin shaft 10 to the left end of the pin sleeve 9; Figure 1 and Figure 2 As shown. When opening the locking box 1, first rotate the push rod so that its axis is parallel to the horizontal plane, then push the push rod to the left until the right end of the pin shaft 10 disengages from the pin sleeve 9. At this time, the left end of the pin shaft 10 is in contact with the calibration key of the remote control 6, the push rod is located in the limiting part 82, and its right end is tangent to the left end of the guide part 83; as shown. Figure 3 and Figure 4 As shown. Lifting it upwards will open the cover 2, revealing the gas cylinder 3 inside the locked box 1 for calibration.

[0030] When the locking box 1 of this device is opened, the calibration button on the remote control 6 must be touched first to put the methane sensor 13 into calibration mode. This can effectively solve the problem of data discrepancies caused by professionals forgetting to put the methane sensor 13 into calibration mode, and essentially solve the problem of false alarm data during calibration, thereby reducing the negative impact on enterprise safety production.

[0031] Example 2

[0032] This embodiment has the same shape, structure, and function as the locking box 1 and box cover 2 in Embodiment 1, and will not be described again here. The difference between this embodiment and Embodiment 1 is that it also includes a gas pipe 12 and a methane sensor 13, with both ends of the gas pipe 12 connected to the methane sensor 13 and the gas outlet 4 of the gas cylinder 3, respectively; as... Figure 6 As shown. After the pin shaft 10 touches the calibration button on the remote control 6, the box cover 2 is opened, and the gas cylinder 3 can be seen. Opening the valve of the gas cylinder 3 completes the calibration operation.
