Description

Technical Field

[0001] The present invention relates to the technical field of mining machinery, and particularly relates to an integrated borehole peeping device. Background Art

[0002] Borehole peeping instruments have been widely used in geological condition assessment during coal mine production and roadway support design. They are mainly used to detect geological structures of roof and overlying surrounding rocks, roof separation of roadway, borehole quality, water pressure fracturing effect, etc. Especially for the detection of borehole quality, water pressure fracturing effect, and rock formation structure of working face roof, they can be intuitively and clearly displayed through a display. Through a digital recorder, it is stored in a computer for technicians to analyze, make objective judgments and decisions in a timely manner. This can not only avoid accidents as much as possible, but also be used as a basis for the support form and parameters of the roadway, reducing unnecessary investment. The video and image data can be saved for permanent records.

[0003] Before borehole peeping, observation holes are first drilled in the two sides or roof of the roadway using a bolt-sling drill, and then the camera of the borehole peeping instrument is placed into the hole for observation. However, most existing peeping instruments are cylindrical, and coal and rock debris will fall onto the top of the peeping instrument during the pushing process, resulting in the camera being unable to effectively observe, and the observation effect being greatly reduced. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated borehole peeping device, which solves the problem that coal and rock debris fall onto the top of the existing borehole peeping instrument during use, resulting in the camera being unable to effectively observe.

[0005] The technical solution adopted by the present invention is an integrated borehole peeping device, including a sleeve. A camera is provided at the end of the sleeve. A plurality of LED lights are further provided around the inner circle of the sleeve near the camera. A gas sensor is also provided inside the sleeve on the side of the LED lights away from the camera. A plurality of slots are also formed around the outer circle of the sleeve side wall, and the slots communicate with the gas sensor. A push rod screw is further provided at the end of the sleeve away from the camera.

[0006] The features of the present invention further lie in:

[0007] A conical sapphire glass protective cover coaxial with the sleeve is connected to the end of the sleeve. A hollow cylinder of the same height as the conical sapphire glass protective cover is further provided at the central axis of the conical sapphire glass protective cover. The camera is embedded at the end of the hollow cylinder and is located at the tip of the conical sapphire glass protective cover;

[0008] Among them, the plurality of LED lights are arranged at the bottom of the conical sapphire glass protective cover, and the plurality of LED lights are evenly distributed around the inner circumference of the bottom of the conical sapphire glass protective cover;

[0009] A plurality of LED reflectors are provided at the bottoms of the plurality of LED lights;

[0010] A plurality of extremely dense metal mesh covers are provided at the openings of the plurality of slots;

[0012] The gas sensor is an MH-440V / D infrared methane gas sensor;

[0013] The push rod screw is located on the central axis of the sleeve;

[0014] An integrated cable is further connected inside the sleeve. The integrated cable is respectively connected to the camera, the LED light and the gas sensor, and the integrated cable is externally connected to a control host;

[0015] The top of the peeping device is conical, and the bottom is a cylindrical sleeve coaxial with the conical top.

[0016] The beneficial effects of the present invention are:

[0017] An integrated drilling peeping device of the present invention redesigned the traditional cylindrical peeping instrument into a new shape with a conical upper part and a cylindrical lower part, solving the problem that the coal and rock powder blocks the camera during the advancement of the observation hole of the drilling peeping device, and can also realize the functions of an ordinary drilling peeping instrument, monitor the gas emission volume in the observation hole, and realize the function of "one hole for multiple uses", especially suitable for high-gas mines.

[0021] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0022] The present invention provides an integrated drilling peeping device, including a nickel-chromium alloy sleeve with a diameter of 30 mm. The upper conical part of the device is the imaging part, and the inside of the sleeve is the gas detection part;

[0023] Such as Figure 1As shown in the figure, the specific structure of the conical camera part is as follows: A conical sapphire glass protective cover 3 coaxial with the sleeve is connected to the end of the sleeve. Inside the conical sapphire glass protective cover 3, at the central axis of the conical sapphire glass protective cover 3, there is also a 5-mm-diameter hollow cylinder 2 with the same height as the conical sapphire glass protective cover 3. The hollow cylinder 2 is used to hold the camera 1. The camera 1 is embedded at the end of the hollow cylinder 2 and is located at the tip of the conical sapphire glass protective cover 3, that is, the high-definition camera 1 is located at the top of the entire device. A plurality of the LED lights 4 are evenly distributed around the inner circumference of the bottom of the conical sapphire glass protective cover 3. At the bottom of each of the plurality of LED lights 4, there is an LED reflector for concentrating light;

[0024] The specific structure of the gas detection part is as follows: Inside the sleeve, on the side of the LED light 4 away from the camera 1, there is also a gas sensor 7. The gas sensor 7 is an MH-440V / D infrared methane gas sensor. As Figure 2 shown, three slots 9 are also provided around the outer circumference of the sleeve side wall. The three slots 9 are evenly distributed around the position on the sleeve side wall corresponding to the gas sensor 7. The openings of the slots 9 are all provided with extremely dense metal mesh covers 6. The slots 9 communicate with the gas sensor 7. At the end of the sleeve away from the camera 1, there is also a push rod screw 8. The push rod screw 8 is located on the central axis of the sleeve;

[0025] An integrated cable 5 is also connected inside the sleeve. The integrated cable 5 is respectively connected to the camera 1, the LED light 4, and the gas sensor 7. The integrated cable 5 is externally connected to a borehole peeping host.

[0026] The conical sapphire glass protective cover 3 protects precision instruments such as the camera 1 and the LED light 4 in this device, and has the advantages of anti-scratch, anti-oxidation, and high strength. To solve the problem that when part of the camera 1 enters the borehole, since there may be some crushed stones or crushed coal with relatively large particle diameters, it is very easy to block the camera, resulting in incomplete images or videos and making it difficult to see all the images around the borehole. After changing the cylindrical shape of the traditional peeping instrument to a conical shape in the camera part of this device, this problem can be effectively solved: The upper frustum diameter of the conical sapphire glass protective cover, that is, the position where the camera 1 is installed, is only 10 mm. The coal and rock chips generated during the forward movement of the peeping device can slide down along this conical glass protective cover, and will not hinder the camera 1, avoiding the situation where the conventional peeping instrument cannot be observed anymore due to coal and rock chips on the protective glass in front of the camera;

[0027] The main body of the borehole peeping device is a nickel-chromium alloy sleeve with a diameter of 30 mm. There are 3 slots 9 with a length of 40 mm and a width of 10 mm in the middle position of the sleeve. An MH-440V / D infrared methane gas sensor with a size of 20×16.6 mm is installed in the middle of the sleeve to monitor the gas content. A very dense metal mesh 6 is installed at the notch of the slot 9 to protect the sensor and allow the gas in the observation hole to flow. The integrated circuit 5 mainly supplies power and transmits signals for the camera and the sensor. All video signals, the transmission and recording of the gas concentration are completed in the borehole peeping host.
