[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0029] The downhole safety protection device of this invention includes a housing 1, a first support member 2 and a second support member 3, a door panel 4, and a camera 5. The housing 1 has a chamber 101. The first support member 2 and the second support member 3 are arranged at a distance from each other in the height direction of the housing 1. The first support member 2 is connected to one end of the housing 1, and the second support member 3 is connected to the other end of the housing 1 to provide a connection in the height direction of the housing 1 (e.g., ...). Figure 1 The housing 1 is closed in the vertical direction shown. One end of the door panel 4 is connected to the first support member 2, and the other end of the door panel 4 is connected to the second support member 3. The housing 1 has an opening 103 in the direction facing the door panel 4. The door panel 4 is pivotally connected to the housing 1, and the door panel 4 is located at the opening 103 to open or close the housing 1. The camera 5 is connected to the second support member 3. The camera 5 is located in the chamber 101, and the camera 5 is located near the opening 103.
[0030] Specifically, such as Figures 1-4 As shown, the upper end of the first support member 2 is connected to the lower end of the housing 1, the lower end of the second support member 3 is connected to the upper end of the housing 1, the upper end of the door panel 4 is connected to the second support member 3, the lower end of the door panel 4 is connected to the first support member 2, the left end of the door panel 4 is pivotally connected to the right end of the housing 1, and the door panel 4 is located at the opening 103. The upper end of the camera 5 is connected to the lower end of the second support member 3, and the camera 5 is located near the opening 103.
[0031] It should be noted that the door panel 4 has a first position and a second position. In the first position, the door panel 4 closes the right side of the housing 1, that is, the door panel 4 and the housing 1 form a tight connection to form a sealed chamber 101. In the second position, the door panel 4 opens the right side of the housing 1, that is, the door panel 4 rotates relative to the housing 1 to open the right side of the housing 1. For example, the door panel 4 is provided with a handle 401 to facilitate the staff to adjust the position of the door panel 4.
[0032] In this embodiment of the invention, the first support member 2 and the second support member 3 are connected to the housing 1, so that the first support member 2 and the second support member 3 close the housing 1 in the vertical direction. By adjusting the position of the door panel 4, the right side of the housing 1 is in a closed or open state. When the door panel 4 is in the first position, one end of the door panel 4 abuts against the front or rear end of the housing 1, and the door panel 4 closes the right side of the housing 1 to form a sealed chamber 101 to prevent coal ash from entering. When the door panel 4 is in the second position, one end of the door panel 4 is pivotally connected to the front or rear end of the housing 1, and the door panel 4 opens the right side of the housing 1. Moreover, by setting the camera 5 towards the opening 103, the camera 5 can take pictures of the working face to observe the working situation of the working face.
[0033] Compared to the open setup of the camera 5 in related technologies, the embodiment of the present invention connects the first support member 2 and the second support member 3 to the housing 1, and the door panel 4 is pivotally connected to the housing 1. When the camera 5 needs to work, the door panel 4 rotates to open the right end of the housing 1, and the camera 5 takes pictures of the working surface. When the camera 5 does not need to work, the door panel 4 rotates to close the right end of the housing 1 to form a sealed chamber 101, which prevents dust from entering the interior of the safety device, thereby preventing the camera 5 from being covered by dust and ensuring the normal operation of the camera 5.
[0034] In some embodiments, the downhole safety protection device further includes a water storage component 6, which includes a water storage tank 601 and a nozzle 602. The water storage tank 601 is connected to the nozzle 602 to spray water from the water storage tank 601 into the chamber 101. The first support member 2 is provided with a groove 201 in the direction of the second support member 3. The water storage tank 601 is connected to the first support member 2 and is disposed in the groove 201.
[0035] Specifically, the water storage component 6 is located inside the chamber 101 and is connected to the first support member 2. The upper end of the first support member 2 has a groove 201, and the water storage tank 601 is installed inside the groove 201 to avoid occupying space inside the chamber 101. The water storage tank 601 is connected to the nozzle 602 so that the water in the water storage tank 601 can be sprayed into the chamber 101 through the nozzle 602.
[0036] Optionally, the water storage assembly 6 also includes a connecting pipe 603 and a water pump 604. The left end of the connecting pipe 603 is connected to the water storage tank 601, the right end of the connecting pipe 603 is connected to the water inlet of the water pump 604, and the water outlet of the water pump 604 is connected to the nozzle 602. The water in the water storage tank 601 is transferred to the nozzle 602 through the connecting pipe 603 and the water pump 604. The water is sprayed into the chamber 101 through the nozzle 602. The water mist sprayed by the nozzle 602 is used to eliminate coal ash in the chamber 101 and ensure the environment inside the shell 1.
[0037] Optionally, the water storage assembly 6 also includes a telescopic hose 605. The inlet end of the telescopic hose 605 is connected to the outlet end of the water pump 604, and the outlet end of the telescopic hose 605 is connected to the nozzle 602. When it is necessary to remove coal ash, the water in the water storage tank 601 can be removed from the coal ash in the chamber 101 and the working face through the nozzle 602 by the telescopic hose 605, so as to prevent the workers from inhaling coal ash during the work process.
[0038] In some embodiments, the downhole safety protection device further includes a filter assembly 7. A through hole 102 is provided on the housing 1. The filter assembly 7 is connected to the housing 1 and is installed at the through hole 102 to connect the chamber 101 with the outside. The filter assembly 7 includes a grid plate 701 and a filter element (not shown in the figure). The grid plate 701 and the filter element are arranged at intervals in the extending direction of the through hole 102.
[0039] Specifically, a through hole 102 is provided at the front end of the housing 1, which extends through the housing 1 in the front-to-back direction to ensure air circulation between the inside and outside of the housing 1. The filter assembly 7 is connected to the housing 1 and is installed at the through hole 102.
[0040] Optionally, the filter assembly 7 includes symmetrically arranged grille plates 701 and a filter element disposed between the two grille plates 701. Air passes through the grille plates 701 and then through the filter plates into the housing 1. The air entering the housing 1 is filtered by the filter element.
[0041] For example, the filter assembly 7 also includes a ventilation fan 702, which is located near and spaced apart from the rear grille 701. The rotation of the ventilation fan 702 accelerates the flow of air inside and outside the housing 1 and improves the ventilation efficiency.
[0042] Understandably, when workers encounter danger in the mine, they can enter the shell 1, close the door 4, filter the air entering the shell 1 through the filter assembly 7, and accelerate the airflow speed through the ventilation fan 702 to ensure normal breathing for the workers inside the safety protection device. In addition, workers can also drink the water in the water storage tank 601 to ensure their safety.
[0043] For example, the ventilation fan 702 is connected to a storage battery, which provides power to the ventilation fan 702.
[0044] In some embodiments, the downhole safety protection device further includes a first connector 8, which is disposed in the chamber 101, and one end of the first connector 8 is connected to the first support 2, and the other end of the first connector 8 is connected to the second support 3.
[0045] Specifically, the lower end of the first connector 8 is connected to the upper end of the first support 2, the upper end of the first connector 8 is connected to the lower end of the second support 3, and the first connector 8 is located inside the chamber 101.
[0046] In this embodiment of the invention, the first support member 2 and the second support member 3 are connected into a whole by the first connector 8, which improves the connection stability of the first support member 2 and the second support member 3, and thus improves the structural stability of the safety protection device.
[0047] In some embodiments, the number of first connectors 8 is set to multiple, and the multiple first connectors 8 are arranged at intervals in the length direction and / or width direction of the housing 1.
[0048] Specifically, a plurality of first connectors 8 are arranged at intervals along the length of the housing 1, and / or a plurality of first connectors 8 are arranged at intervals along the width of the housing 1. The arrangement of a plurality of first connectors 8 improves the connection stability between the first support 2 and the second support 3.
[0049] For example, the number of first connectors 8 is set to four. Two of the first connectors 8 are set in the left-right direction of the housing 1, and two of the first connectors 8 are set in the front-back direction of the housing 1. The embodiments of the present invention do not limit the number of first connectors 8, and the actual implementation shall prevail.
[0050] In some embodiments, the downhole safety protection device further includes a third support member 9, which is connected to the second support member 3, and the third support member 9 and the second support member 3 are arranged at intervals in the height direction of the housing 1.
[0051] Specifically, the third support member 9 is located above the second support member 3, and the upper end of the second support member 3 is connected to the lower end of the third support member 9. By setting the third support member 9 above the second support member 3 to form a double-layer support, the impact resistance of the safety protection device is strengthened, and the structural strength of the safety protection device can be improved.
[0052] For example, when an object falls onto the safety protection device from above, the third support plate absorbs and transmits the impact of the object to the second support member 3, thus preventing the object from directly impacting the second support member 3 and improving the safety performance of the safety protection device.
[0053] In some embodiments, the downhole safety protection device further includes a second connector 10, one end of which is connected to a third support member 9, and the other end of which is connected to a second support member 3.
[0054] Specifically, the upper end of the second connector 10 is connected to the lower end of the third support 9, and the lower end of the second connector 10 is connected to the upper end of the second support 3. By setting the second connector 10, a gap exists between the second support 3 and the third support 9 in the vertical direction, thereby improving the ability of the third support 9 to withstand and absorb impact forces.
[0055] For example, the number of second connectors 10 is set to be multiple, the second connectors 10 are located above the housing 1, the multiple second connectors 10 are arranged at intervals in the length direction of the housing 1, and / or the multiple second connectors 10 are arranged at intervals in the width direction of the housing 1. By setting multiple second connectors 10, the connection stability between the second support 3 and the third support 9 is improved.
[0056] For example, the number of second connectors 10 is set to six. Three of the second connectors 10 are set in the left-right direction of the housing 1, and two of the second connectors 10 are set in the front-back direction of the housing 1. The embodiments of the present invention do not limit the number of second connectors 10, and the actual implementation shall prevail.
[0057] In some embodiments, the downhole safety protection device further includes a fixing plate 11, which is connected to the first support member 2. There are multiple fixing plates 11, which are arranged at intervals in the circumferential direction of the first support member 2.
[0058] Specifically, one end of the fixing plate 11 is connected to the first support member 2, and the fixing plate 11 extends in the front-back direction. The fixing plate 11 is arranged parallel to the first support member 2. Multiple fixing plates 11 are arranged at intervals in the circumferential direction of the first support member 2, which facilitates the fixing of the first support member 2 and thus the fixing of the safety protection device.
[0059] For example, the number of fixing plates 11 is set to four. Two fixing plates 11 are set in the left-right direction and two fixing plates 11 are set in the front-back direction. That is, the rear end of the fixing plate 11 set at the front end of the first support member 2 is connected to the front end of the first support member 2, and the front end of the fixing plate 11 set at the rear end of the first support member 2 is connected to the rear end of the first support member 2. The present invention does not impose a specific limit on the number of fixing plates 11, as long as the position of the first support member 2 can be fixed.
[0060] In some embodiments, the downhole safety protection device further includes a fixing member 12, on which a threaded hole (not shown) is provided, and one end of the fixing member 12 extends into the ground through the threaded hole.
[0061] Specifically, the fixing plate 11 has a threaded hole that extends through the fixing plate 11 in the vertical direction, and the lower end of the fixing member 12 extends into the ground through the threaded hole to fix the first support member 2 on the ground.
[0062] For example, the fixing member 12 is an adjusting screw. The outer side of the adjusting screw is provided with threads, which correspond to the threaded holes on the fixing plate 11. The upper end of the adjusting screw is provided with a handwheel 1201, and the lower end of the adjusting screw is connected to the fixing head 1202. By rotating the handwheel 1201, the adjusting screw is adjusted to the depth of the fixing head 1202 extending into the ground, so as to insert the fixing head 1202 into the ground and thus fix the position of the first support member 2.
[0063] In some embodiments, the downhole safety protection device further includes an anchor 13, one end of which is connected to the end of the first support 2 away from the second support 3, and the other end of the anchor 13 is adapted to extend into the ground.
[0064] Specifically, such as Figure 5 As shown, the lower end of the first support member 2 is provided with an anchor 13. The lower end of the anchor 13 can be inserted into the ground to a certain depth to fix the first support member 2 to the ground. The anchor 13 improves the connection between the safety protection device and the ground, thereby improving the stability of the safety protection device.
[0065] For example, the number of anchors 13 is set to multiple, and the multiple anchors 13 are arranged in a rectangular array at the lower end of the first support member 2.
[0066] Optionally, such as Figure 6 As shown, the downhole safety protection device also includes casters 14, which are connected to the lower end of the first support member 2. When the safety protection device needs to be fixed on the ground, the casters 14 are adjusted to the locked state. When the safety protection device needs to be moved, the casters 14 are adjusted to the moving state. The casters 14 enable the safety protection device to slide and move at the downhole working face, improving the convenience of moving the safety protection device.
