Description

Technical Field

[0001] The present application relates to the field of gas detection devices, and in particular to a mining safety production detection device. Background Art

[0002] Safe production is the basic guarantee for protecting the safety, health and state property of workers and promoting the development of social productivity. Therefore, doing a good job in safe production is of great significance.

[0003] In recent years, my country's mining industry has developed rapidly, but harmful gases such as carbon monoxide, hydrogen sulfide and methane are often present in mines, posing a serious threat to the safety of miners.

[0004] To sum up, coal mine gas detection and analysis is the necessary basis for ensuring coal mine safety and the fundamental basis for coal mine disaster prevention, control and disaster relief decisions. At the same time, coal mines are often located in areas far away from the surface. Therefore, before mining operations, it is usually necessary to use harmful gas detection devices to confirm whether the harmful gases in the mine meet the standards for workers to safely enter the mine, and then detect the oxygen in the mine to ensure that the oxygen inside the mine is sufficient to meet the workers' production work.

[0005] With respect to the above-mentioned related technologies, the inventors believe that the existing detection devices are unable to detect oxygen and harmful gases at the same time, and detecting them separately is time-consuming and labor-intensive, which can easily interrupt the continuity of the detection operation. Utility Model Content

[0006] In order to improve the continuity of detection operations, the present application provides a mining safety production detection device

[0007] The present application provides a mining safety production detection device that adopts the following technical solution:

[0008] A mining safety production detection device includes a mounting plate, on which a first control unit is arranged, on which a first storage unit and an oxygen detection device connected to the first storage unit are also arranged; on which a second control unit is also arranged, on which a second storage unit and a harmful gas detection device connected to the second storage unit are also arranged.

[0009] Place the mounting plate at the designated detection position, start the first control unit to start the oxygen detection device, the oxygen detection device transmits the detected oxygen concentration data to the first storage unit, and at the same time start the second control unit to start the harmful gas detection device, the harmful gas detection device transmits the detected harmful gas content data to the second storage unit. Since the mounting plate is provided with both the oxygen detection device and the harmful gas detection device, the oxygen concentration detection and the harmful gas content detection can be performed with the same device, which saves the time consumed in replacing the detection device and improves the continuity of the detection operation.

[0010] Optionally, a protective shell is provided on the periphery of the mounting plate, and the oxygen detection device and the harmful gas detection device both extend out of the protective shell.

[0011] By adopting the above technical solution, the setting of the protective shell protects the mounting plate to a certain extent, making the mounting plate safer and less prone to damage during movement. At the same time, the setting of the handle also makes the mounting plate more portable and practical.

[0012] Optionally, a storage box is further provided outside the protective shell, the mounting plate is penetrated by a first through hole, the protective shell is penetrated by a second through hole, the storage box is penetrated by a third through hole connected to the second through hole, and the storage box is provided with a rotating shaft for rotating the protective shell, and the rotating shaft passes through the storage box through the third through hole.

[0013] By adopting the above technical solution, the setting of the storage box further protects the mounting plate, and the setting of the rotating shaft enables the protective shell to drive the oxygen detection device and the harmful gas detection device to be rotated out of the storage box for detection. While protecting the harmful gas detection device and the oxygen detection device, it can also achieve the purpose of detecting the gas inside the mine.

[0014] Optionally, a limiting component for limiting the movement of the protective shell is provided between the protective shell and the storage box.

[0015] By adopting the above technical solution, the setting of the limiting component allows the protective shell to be fixed at a specified position, so that the harmful gas detection device or the oxygen detection device can perform detection at the specified position, thereby improving the accuracy of the detection.

[0016] Optionally, the limiting assembly includes a first convex strip arranged on the protective shell, and a first I-shaped limiting block arranged on the inner wall of the storage box and adapted to the first convex strip. The protective shell is also provided with a second convex strip and a second I-shaped limiting block adapted to the second convex strip.

[0017] The protective shell is turned out from the storage box, and the rotation of the protective shell drives the harmful gas detection device to rotate. At this time, the first convex strip slides into the first I-shaped limit block, and the second convex strip slides into the second I-shaped limit block. Conversely, when the oxygen detection device is rotated, the first convex strip slides into the second I-shaped limit block, and the second convex strip slides into the first I-shaped limit block, thereby realizing the relative fixation between the protective shell and the storage box, thereby improving the accuracy of the detection.

[0018] Optionally, a plurality of accommodating grooves are formed on the outer side wall of the storage box, and a plurality of legs corresponding to the plurality of accommodating grooves are hingedly connected to the storage box, and each of the legs is accommodated in the accommodating groove corresponding thereto.

[0019] By adopting the above technical solution, after placing the storage box at the designated detection point, the legs are rotated out of the accommodating grooves. The setting of the legs makes the storage box more stable during the detection process, so that the oxygen detection device and the harmful gas detection device can perform stable detection, further improving the detection accuracy.

[0020] Optionally, a telescopic leg is slidably inserted in each of the legs, a supporting foot is hinged on each of the telescopic legs, and fastening bolts are provided between the telescopic legs.

[0021] By adopting the above technical solution, after the support leg is extended, the auxiliary leg can be slid out of the support leg and the support foot can be opened. After determining that the height of the storage box is appropriate, the fastening bolts are tightened to make the auxiliary leg relatively fixed. The setting of the auxiliary leg allows the storage box to be located at different heights, thereby expanding the detection range of the oxygen detection device and the harmful gas detection device and improving the detection accuracy.

[0022] Optionally, a slide assembly is further provided on the storage box, and the slide assembly is used to control the rotation and closure of the legs.

[0023] By adopting the above technical solution, the setting of the sliding block assembly ensures that the legs will not rotate out of the accommodating grooves during the movement of the storage box, thereby improving the portability of the folded legs.

[0024] Optionally, the sliding block assembly includes a plurality of groups of sliding grooves opened on the outer side wall of the storage box, each group of the sliding grooves corresponds to one of the accommodating grooves, and the inner side wall of each group of the sliding grooves is slidably connected with a baffle.

[0025] By adopting the above technical solution, after placing the storage box in the designated position, push the baffle upwards, the baffle slides to the top of the slide slot, and then the legs are rotated out. After the inspection is completed, slide the baffle to the top of the slide slot again, and then put the legs back and release the baffle. The baffle naturally slides down to block the legs. The setting of the baffle reduces the possibility of the legs rotating out of the storage slot due to shaking, thereby improving the applicability of the legs.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Since both the oxygen detection device and the harmful gas detection device are installed on the mounting plate, the detection of oxygen concentration and the detection of harmful gas content can be carried out at the same time, which saves the time consumed in replacing the detection device and improves the continuity of the detection operation;

[0028] 2. The setting of the storage box further protects the mounting plate, and the setting of the rotating shaft allows the protective shell to protect the oxygen detection device and the harmful gas detection device while not affecting the oxygen detection device and the harmful gas detection device from being rotated out of the storage box to detect the gas inside the mine;

[0029] 3. After the legs are extended, the telescopic legs can be slid out and the legs can be opened. After determining that the height of the storage box is appropriate, tighten the fastening bolts to fix the relative positions of the legs and the telescopic legs. The setting of the telescopic legs allows the storage box to be located at different heights, thereby expanding the detection range of the oxygen detection device and the harmful gas detection device and improving the detection accuracy.

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] The present application embodiment discloses a mining safety production detection device. Figure 1 and Figure 2 A mining safety production detection device includes a mounting plate 1, and two end surfaces of the mounting plate 1 that are far away from each other are respectively provided with an oxygen detection device 12 and a harmful gas detection device 13. A first control unit 14 is also provided on the mounting plate 1, and the first control unit 14 is electrically connected to the oxygen detection device 12. The first control unit 14 is also electrically connected to a first storage unit 141 for receiving oxygen detection data; a second control unit 15 is also provided on the mounting plate 1, and the second control unit 15 is electrically connected to the harmful gas detection device 13. The second control unit 15 is also electrically connected to a second storage unit 151 for receiving harmful gas detection data. A first through hole 16 is also opened on the mounting plate 1, and the first through hole 16 is located between the oxygen detection device 12 and the harmful gas detection device 13.

[0039] When underground operations are required, the staff will place the mounting plate 1 at the designated position. Since the mounting plate 1 is equipped with both the oxygen detection device 12 and the harmful gas detection device 13, the oxygen detection result will be transmitted to the first storage unit 141. At the same time, the harmful gas detection result will be transmitted to the second storage unit 151. By analyzing the data in the first storage unit 141 and the second storage unit 151, the oxygen concentration and harmful gas conditions in the mine can be known at the same time, and then the subsequent underground operations can be arranged according to the detection results.

[0040] Since the mounting plate 1 is provided with both the oxygen detection device 12 and the harmful gas detection device 13, the oxygen concentration and the harmful gas situation in the mine can be detected and analyzed simultaneously, thus saving the time consumed in replacing the detection device and improving the continuity of the detection operation.

[0041] A protective shell 2 is fixedly provided on the mounting plate 1, a second through hole 21 is penetrated through the protective shell 2, and the second through hole 21 corresponds to the position of the first through hole 16, the oxygen detection device 12 and the harmful gas detection device 13 extend out of the protective shell 2, and two pull handles 22 are fixedly connected to the side wall of one side of the protective shell 2.

[0042] During the inspection, the staff holds the two handles 22 to place the protective shell 2 at the designated inspection position. Since the oxygen detection device 12 and the harmful gas detection device 13 extend out of the protective shell 2, oxygen and harmful gases can still be directly detected. After the inspection is completed, the protective shell 2 can be removed by holding the two handles 22.

[0043] The protective shell 2 protects the components such as the first control unit 14, the second control unit 15, the first storage unit 141 and the second storage unit 151 on the mounting plate 1 to a certain extent, thereby improving the operating stability of the oxygen detection device 12 and the harmful gas detection device 13.

[0044] Reference Figure 2 and Figure 3 A storage box 3 is also provided outside the protective shell 2. The storage box 3 is a rectangular parallelepiped structure with an open top and a hollow interior. The protective shell 2 is accommodated in the space inside the storage box 3. A third through hole 31 that is directly opposite to the second through hole 21 is penetrated on the side wall of the storage box 3, and a rotating shaft 32 is rotatably connected to the storage box 3. The rotating shaft 32 penetrates the storage box 3 and passes through the third through hole 31 and the second through hole 21. A handle 33 is also fixedly connected to the outer wall on one side of the storage box 3.

[0045] After holding the handle 33 to transport the storage box 3 to the designated detection point, pull the handle 22 to unscrew the harmful gas detection device 13. During this process, the protective shell 2 rotates around the shaft 32 to drive the mounting plate 1 to rotate to a suitable position. After the harmful gas detection is completed, the harmful gas detection device 13 is rotated back to its original position, and then the protective shell 2 is rotated to unscrew the oxygen detection device 12 to the same position for detection. After the oxygen concentration detection is completed, repeat the above steps to turn the protective shell 2 back to its original position.

[0046] The storage box 3 further protects the components inside the protective shell 2 located inside the storage box 3 . The provision of the handle 33 makes the storage box 3 more portable, thereby improving the applicability of the oxygen detection device 12 and the harmful gas detection device 13 .

[0047] Reference Figure 1 , Figure 2 and Figure 4 A limiting component 4 is provided between the storage box 3 and the protective shell 2, and the limiting component 4 is used to fix the protective shell 2 at a specified position during the rotation process.

[0048] The limiting assembly 4 includes a first ridge 41 and a second ridge 42 fixedly arranged on the protective shell 2, and the first ridge 41 and the second ridge 42 are relatively arranged with the second through hole 21 as the center, and a first I-shaped limiting block 43 and a second I-shaped limiting block 44 are provided on the inner wall of the storage box 3, the first ridge 41 is plugged into the first I-shaped limiting block 43, and the second ridge 42 is plugged into the second I-shaped limiting block 44.

[0049] When the protective shell 2 rotates the harmful gas detection device 13 out with the rotating shaft 32 as the axis, the first convex strip 41 slides and inserts into the first I-shaped limit block 43, and at the same time, the second convex strip 42 slides and inserts into the second I-shaped limit block 44. When the oxygen detection device 12 is rotated out, the second convex strip 42 slides and inserts into the first I-shaped limit block 43, and the first convex strip 41 slides and inserts into the second I-shaped limit block 44.

[0050] Through the above arrangement, the oxygen detection device 12 or the harmful gas detection device 13 will not be offset during the detection process, thereby achieving the effect of fixing the oxygen detection device 12 and the harmful gas detection device 13 at the specified position, thereby improving the accuracy and stability of the detection.

[0051] Reference Figure 3 and Figure 5 A plurality of accommodating grooves 5 are provided on the storage box 3. In the present embodiment, four accommodating grooves 5 are provided. The four accommodating grooves 5 are divided into two groups, and the two groups of accommodating grooves 5 are evenly distributed on two outer walls of the storage box 3 away from each other. The inner side walls of the four accommodating grooves 5 away from the opening end of the storage box 3 are rotatably connected with supporting legs 6.

[0052] After the storage box 3 is lifted to the designated detection point, the legs 6 are rotated out of the accommodating grooves 5. The four legs 6 make the storage box 3 more stable during the detection process, thereby making the oxygen detection device 12 and the harmful gas detection device 13 more stable during the detection process.

[0053] Reference Figure 5 The four legs 6 are hollow inside, and the inner walls of the four legs 6 close to the top opening of the storage box 3 are slidably connected with telescopic legs 61, and the ends of the telescopic legs 61 located at one end of the outside of the legs 6 are hinged with supporting feet 611, and the ends of the legs 6 close to the telescopic legs 61 are provided with fastening bolts 62, which penetrate the legs 6 and the telescopic legs 61, and are threadedly connected to the legs 6 and the telescopic legs 61.

[0054] After the legs 6 are rotated out of the receiving grooves 5, the telescopic legs 61 are pulled out of the legs 6 and the legs 611 are opened. After determining that the height of the storage box 3 is appropriate, the fastening bolts 62 are rotated to fix the relative positions between the legs 6 and the telescopic legs 61, thereby determining the height of the storage box 3 from the ground. Thus, the oxygen detection device 12 and the harmful gas detection device 13 can be detected at appropriate positions, further improving the accuracy of the detection.

[0055] Reference Figure 3 and Figure 5 A plurality of sliding block assemblies 7 are arranged on the outer wall of the storage box 3, and each sliding block assemblies 7 include two sliding grooves 71 and a baffle 72 opened on both sides of the accommodating groove 5. The sliding grooves 71 are opened parallel to the length direction of the accommodating groove 5, and the two ends of the baffle 72 close to one side of the storage box 3 are inserted into the two sliding grooves 71 close to each other.

[0056] When the leg 6 needs to be rotated out, the baffle 72 can be pushed to the top of the slide slot 71 to rotate the leg 6 out. After use, the baffle 72 is pushed to the top of the slide slot 71 again, and then the leg 6 is rotated back into the accommodating slot 5. Then the baffle 72 is released, and the baffle 72 naturally slides down to block the telescopic leg 61, so that the leg 6 will not rotate out of the accommodating slot 5 during the movement of the storage box 3, thereby improving the applicability of the leg 6.

[0057] Reference Figure 1 A buzzer alarm 23 is also provided on the side of the mounting plate 1 , and the buzzer alarm is electrically connected to the second storage unit 151 .

[0058] When the harmful gas content detected by the harmful gas detection device 13 reaches a certain level, the buzzer alarm 23 will sound, thereby letting the staff know that the harmful gas content exceeds the standard.

[0059] Reference Figure 1 , Figure 2 and Figure 6 The outer side walls of the oxygen detection device 12 and the harmful gas detection device 13 are both covered with a sampling cover 24, the top of the sampling cover 24 is open and the lower surface of the sampling cover 24 is fixedly connected to the side wall of the protective shell 2.

[0060] The sampling cover 24 prevents the oxygen detection device 12 and the harmful gas detection device 13 from being directly exposed to the outside to a certain extent, and during sampling, the gas flows from the top opening of the sampling cover 24 to the oxygen detection device 12 and the harmful gas detection device 13 .

[0061] Each sampling cover 24 is provided with a protective cover 25 on the outside. The protective cover 25 is a cylindrical tube structure with openings at both ends. A protective cover 26 is provided on the top of the protective cover 25. The end of the protective cover 26 close to the outer wall of the protective shell 2 is inserted into the protective cover 25, and the outer wall of the protective cover 26 close to the end of the protective shell 2 abuts against the inner wall of the protective cover 25 away from the end of the protective shell 2.

[0062] During detection, the protective cover 26 is pulled out from the protective cover 25, so that the internal sampling cover 24 and the oxygen detection device 12 or the harmful gas detection device 13 located inside the sampling cover 24 can leak out, thereby detecting the gas inside the mine. The protective cover 25 prevents external factors such as dust from easily entering the oxygen detection device 12 or the harmful gas detection device 13 through the top opening of the sampling cover 24, thereby improving the stability of the detection process.

[0063] The implementation principle of a mining safety production detection device in an embodiment of the present application is as follows: lift the storage box 3 to the designated detection location, then hold the handle 22 to unscrew the protective shell 2. During this process, the protective shell 2 drives the harmful gas detection device 13 to be unscrewed and fixed to the designated position, and then the protective cover 26 is pulled off the top of the protective cover 25 to perform harmful gas detection. After the detection is completed, the protective cover 26 is covered and the harmful gas detection device 13 is turned back to its original position. After that, the oxygen detection device 12 is unscrewed, the protective cover 26 is opened, and the oxygen concentration inside the mine is detected. Repeat the above steps and cover the protective cover 26 and turn the oxygen detection device 12 back to its original position after the oxygen concentration detection is completed.

[0064] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
