Description

Technical Field

[0001] This invention belongs to the technical field of mine ventilation equipment, and specifically provides a ventilation volume adjustment device and its usage method. Background Technology

[0002] Mine ventilation refers to the process of introducing fresh air into the mine to increase the oxygen concentration. Mine ventilation is usually used to regulate the underground climate, create a good working environment for workers, supply sufficient fresh air to meet the oxygen needs of personnel, and dilute harmful gases and dust in the mine to ensure clean and unobstructed airflow inside the mine. Since underground work requires a large amount of oxygen, ventilation is essential. Without ventilation, safety and production cannot be guaranteed. Therefore, mine ventilation is the most basic link in the mine production process and has always held a very important position during mine construction and production. During the opening and closing of sealed areas and the release of methane gas, the amount of air supplied is usually controlled according to the actual situation. Therefore, a regulating mechanism is needed to adjust the ventilation volume. The air volume of existing mine ventilation equipment usually needs to be adjusted by the staff at the ventilation main control terminal. However, due to the large space occupied by mine ventilation equipment and the difficulty for staff to adjust the ventilation volume in a timely manner due to changes in the work site, the operation is cumbersome and causes inconvenience to underground workers.

[0003] In the existing technology, by setting up pipes, adjusting plates, central shafts, motors and knobs, the rotation angle of the adjusting plates can be adjusted by the power provided by the motor, thereby adjusting the ventilation volume in the pipes, realizing both automatic and manual air volume adjustment operation modes, and increasing the practicality of the equipment components.

[0004] However, in the aforementioned prior art, the motor is located inside the device and is fixedly connected to the central shaft. When the motor malfunctions, the small internal space of the device increases the difficulty of maintenance for the staff. Summary of the Invention

[0005] To address the above problems, the present invention provides a ventilation volume regulating device and a method for using it.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a ventilation volume regulating device, comprising an equipment component, a pipe, and an auxiliary mechanism. The equipment component is sleeved and assembled on the upper side of the outer wall of the pipe. A motor is assembled inside the equipment component. A first abutment block is provided at the output end of the motor. A central shaft is radially inserted through the inner wall of the pipe. A second abutment block that meshes with the first abutment block is provided at one end of the central shaft. An adjusting plate is assembled on the side wall of the central shaft. A wind speed sensor is assembled on the inner wall of the pipe. The two wind speed sensors are respectively located on both sides of the adjusting plate.

[0007] The auxiliary mechanism includes two screws, two moving blocks, and a U-shaped body. The threads on the surfaces of the two screws are opposite to each other. A rack is provided at the outer end of the moving block. A sealing body is movably assembled at the inner end of the U-shaped body. Moving grooves are provided on the inner sidewalls of the U-shaped body. Rotating grooves are provided on the inner surface of the moving grooves, parallel to the moving grooves. The two screws are rotatably assembled in the rotating grooves, and the threads of the screws mesh with the corresponding racks. The U-shaped body is fixedly installed inside the equipment assembly, and the motor is located between the U-shaped body and the sealing body. The outer end of the sealing body penetrates the outer wall of the equipment assembly. The two moving blocks are fixedly installed on both sides of the motor, and the moving blocks are slidably assembled in the corresponding moving grooves.

[0008] Furthermore, the auxiliary mechanism also includes two rotating disks, which are respectively mounted on the outer end of the screw and are located on the rear end face of the equipment assembly.

[0009] Furthermore, the rotating disk includes a handle and a disk body, with the handle fixedly mounted on the outer surface of the disk body, and the disk body assembled on the outer end of the screw.

[0010] Furthermore, it also includes two flanges and a rotating assembly, the two flanges being fixedly installed at both ends of the pipe, and the rotating assembly being assembled at the other end of the central shaft.

[0011] Furthermore, the rotating assembly includes multiple knobs and a rotating ring, with the multiple knobs integrally formed on the outer wall of the rotating ring, and the rotating ring fixedly installed at the other end of the central shaft.

[0012] Furthermore, the equipment component includes a controller and an equipment body, with the controller fixedly installed on the inner wall of the equipment body, the equipment body fixedly installed on the outer wall of the pipe, the U-shaped body fixedly installed on the inner wall of the equipment body, and the controller electrically connected to the motor.

[0013] Furthermore, the device component also includes an alarm, which is mounted inside the device body and located above the controller.

[0014] A method of using a ventilation volume regulating device, comprising the following steps:

[0015] a. Adjust the air volume

[0016] The controller starts the motor, which drives the central shaft to rotate, which in turn drives the adjusting plate to rotate. When the adjusting plate rotates to the appropriate position, the motor stops, and the air in the duct can flow out through the gap between the adjusting plate and the duct, thus controlling the air volume.

[0017] The airflow speed on both sides of the regulating plate inside the duct is measured in real time by a wind speed sensor, and the speed value is transmitted to the controller to obtain the corresponding air volume. When the air volume is insufficient, the controller will control the motor to drive the regulating plate to rotate, change the angle of the regulating plate inside the duct, and thus adjust the air volume inside the duct.

[0018] b. Replace the motor

[0019] To remove the motor, first adjust the positions of the first and second abutting blocks so that the contact surfaces of the first and second abutting blocks are parallel to the screw. Then rotate the rotating discs on both sides to drive the screw to rotate. Through the transmission of the rack and pinion, the moving block moves outward, thereby driving the motor and the sealing body to move outward within the U-shaped body, and finally remove the motor.

[0020] To install the motor, first place the motor at the front end of the sealing body, and then move the motor and the sealing body together into the U-shaped body until the rack and screw mesh. Then, rotate the rotating disk in the opposite direction. Through the transmission of the screw and rack, the moving block is driven to move inward, while pushing the sealing body into the U-shaped body until the first abutment block on the motor meshes with the second abutment block, thus completing the motor installation.

[0021] Furthermore, a ventilation volume regulating device also includes a pulling component and a fixing component. The fixing component includes two rotating shafts and a handle. The fixing component includes a slider and a fixing rod, and the slider is fixedly installed on the outer wall of one end of the fixing rod. The outer end of the sealing body has a groove, and the rear surface of the device body has a telescopic groove. The handle is rotatably fitted into the groove via the rotating shafts. The fixing rod is inserted into the telescopic groove. The outer side wall of the sealing body has a slot, and the other end of the fixing rod is inserted into the slot. The outer wall of the telescopic groove has a sliding groove, and the slider is located in the sliding groove.

[0022] A method of using a ventilation volume regulating device, comprising the following steps:

[0023] a. Adjust the air volume

[0024] The controller starts the motor, which drives the central shaft to rotate, which in turn drives the adjusting plate to rotate. When the adjusting plate rotates to the appropriate position, the motor stops, and the air in the duct can flow out through the gap between the adjusting plate and the duct, thus controlling the air volume.

[0025] The airflow speed on both sides of the regulating plate inside the duct is measured in real time by a wind speed sensor, and the speed value is transmitted to the controller to obtain the corresponding air volume. When the air volume is insufficient, the controller will control the motor to drive the regulating plate to rotate, change the angle of the regulating plate inside the duct, and thus adjust the air volume inside the duct.

[0026] b. Replace the motor

[0027] Remove the motor, first adjust the positions of the first and second abutting blocks so that the contact surfaces of the first and second abutting blocks are parallel to the screw. Move the slider to move the fixing rod out of the slot of the sealing body, and remove the sealing body by the handle. Then rotate the rotating disks on both sides to drive the screw to rotate. Through the transmission of the rack and pinion, the moving block moves outward and finally the motor is removed.

[0028] To install the motor, first place the motor at the front end of the sealing body, and then move the motor and the sealing body together into the U-shaped body until the rack and screw engage. Then, rotate the rotating disk in the opposite direction. Through the transmission of the screw and rack, the moving block moves inward. At the same time, push the sealing body into the U-shaped body with the handle until the first abutment block on the motor engages with the second abutment block. Then, move the slider to move the fixing rod into the slot of the sealing body, thus completing the installation of the motor.

[0029] The beneficial effects of using this invention are:

[0030] This invention designs a device component in which a rotating disk drives a screw to rotate. The motor can be removed via rack and pinion transmission, and vice versa, the motor can be easily placed in for use. This method allows the motor to be housed inside the device, thus protecting the motor and facilitating its replacement and repair when problems occur. It avoids the technical difficulties that arise from the limited internal space of the device, which would otherwise increase the difficulty of maintenance for workers.

[0031] The present invention designs a first abutment block connected to the motor and a second abutment block connected to the central shaft, so that the two can effectively transmit power after meshing, and can be easily and effectively separated and meshed, thereby enabling the replacement and maintenance of the motor to be completed smoothly.

[0032] The invention also includes a wind speed sensor that can monitor the wind speed in the pipeline in real time and control the motor through a controller to adjust the angle of the regulating plate, thereby adjusting the ventilation volume in a timely manner and increasing the safety of miners.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] Reference Figures 1 to 9 A ventilation volume regulating device includes an equipment component 101, a pipe 102, and an auxiliary mechanism. The equipment component 101 is sleeved and assembled on the upper side of the outer wall of the pipe 102. A motor 103 is installed inside the equipment component 101. A first abutment block 104 is provided at the output end of the motor 103. A central shaft 105 is radially inserted through the inner wall of the pipe 102. A second abutment block 106 that meshes with the first abutment block 104 is provided at one end of the central shaft 105. An adjusting plate 107 is installed on the side wall of the central shaft 105. A wind speed sensor 108 is installed on the inner wall of the pipe 102. The two wind speed sensors 108 are located on both sides of the adjusting plate 107.

[0051] Gas is transported via pipe 102.

[0052] The motor 103 provides power, which drives the central shaft 105 and the adjusting plate 107 to rotate after transmission, thereby adjusting the angle of the adjusting plate 107 and realizing the adjustment of the air volume through the pipe 102.

[0053] The lower surface of the first supporting block 104 is integrally formed with a first protrusion, and the upper surface of the second supporting block 106 is integrally formed with a second protrusion corresponding to the first protrusion. The first protrusion and the second protrusion engage with each other, and the contact surface between the first protrusion and the second protrusion is a plane, which facilitates the installation and separation of the motor 103 and the central shaft 105.

[0054] Two wind speed sensors 108 measure the air velocity on both sides of the regulating plate 107 and transmit the data to the controller 121.

[0055] like Figures 4 to 8As shown, the auxiliary mechanism includes two screws 109, two moving blocks 110, and a U-shaped body 111. The threads on the surfaces of the two screws 109 are opposite to each other. A rack 112 is provided at the outer end of the moving block 110. A sealing body 113 is movably assembled at the inner end of the U-shaped body 111. Moving grooves 114 are provided on the inner sidewalls of the U-shaped body 111. A rotating groove 115 parallel to the moving groove 114 is provided on the inner surface of the moving groove 114. The two screws 109 are rotatably assembled in the rotating grooves 115 respectively, and the threads of the screws 109 mesh with the corresponding racks 112. The U-shaped body 111 is fixedly installed inside the equipment assembly 101, and the motor 103 is located between the U-shaped body 111 and the sealing body 113. The outer end of the sealing body 113 penetrates the outer wall of the equipment assembly 101. The two moving blocks 110 are fixedly installed on both sides of the motor 103 respectively, and the moving blocks 110 are slidably assembled in the corresponding moving grooves 114.

[0056] The front end of the sealing body 113 is semi-cylindrical in shape. When it is fitted with the U-shaped body 111, it forms a cylindrical space. The motor 102 is located in this cylindrical space. Therefore, the motor 102 can be fixed by the fit between the U-shaped body 111 and the sealing body 113.

[0057] When the screw 109 rotates, it drives the moving block 110 to move through the rack 112, which in turn drives the motor 103 to move, thus making it easy to install and remove the motor 103.

[0058] Specifically, such as Figure 5 As shown, the auxiliary mechanism also includes two rotating disks, which are respectively mounted on the outer end of the screw 109 and are located on the rear end face of the equipment assembly 101.

[0059] Specifically, such as Figure 5 As shown, the rotating disk includes a handle 116 and a disk body 117, with the handle 116 fixedly mounted on the outer surface of the disk body 117, and the disk body 117 assembled on the outer end of the screw 109.

[0060] The screw 109 can be rotated by rotating the rotating disk.

[0061] Specifically, such as Figure 1 and Figure 2 As shown, it also includes two flanges 118 and a rotating assembly. The two flanges 118 are fixedly installed at both ends of the pipe 102, and the rotating assembly is assembled at the other end of the central shaft 105.

[0062] Pipe 102 is easily installed via flange 118.

[0063] Specifically, such as Figure 8 and Figure 9As shown, the rotating assembly includes multiple knobs 119 and a rotating ring 120. The multiple knobs 119 are integrally formed on the outer wall of the rotating ring 120, and the rotating ring 120 is fixedly installed on the other end of the central shaft 105.

[0064] By rotating the rotating assembly, the central shaft 105 can be rotated manually, thereby allowing manual adjustment of the angle of the adjusting plate 107.

[0065] Specifically, such as Figure 8 As shown, the equipment component 101 includes a controller 121 and an equipment body 122. The controller 121 is fixedly installed on the inner wall of the equipment body 122, the equipment body 122 is fixedly installed on the outer wall of the pipe 102, the U-shaped body 111 is fixedly installed on the inner wall of the equipment body 122, and the controller 121 is electrically connected to the motor 103.

[0066] Specifically, such as Figure 8 As shown, the device component 101 also includes an alarm 123, which is mounted inside the device body 122 and is located above the controller 121.

[0067] Alarm 123 serves as a warning device; it will sound an alarm when the gas flow through pipe 102 is low.

[0068] Example 2

[0069] The difference from Example 1 is that:

[0070] like Figures 10 to 13 As shown, a ventilation volume regulating device further includes a pulling component and a fixing component. The fixing component includes two rotating shafts 201 and a handle 202. The fixing component includes a slider 205 and a fixing rod 206. The slider 205 is fixedly installed on the outer wall of one end of the fixing rod 206. The outer end of the sealing body 113 has a groove 203. The rear surface of the equipment body 122 has a telescopic groove 204. The handle 202 is rotatably assembled in the groove 203 through the rotating shaft 201. The fixing rod 206 is inserted into the telescopic groove 204. The outer side wall of the sealing body 113 has a slot, and the other end of the fixing rod 206 is inserted into the slot. The outer wall of the telescopic groove 204 has a sliding groove, and the slider 205 is located in the sliding groove.

[0071] By engaging the fixing rod 206 with the slot on the sealing body 113, the position of the sealing body 113 can be limited after the motor 103 is installed, thereby fixing the position of the motor 103, ensuring effective engagement between the first abutment block 104 and the second abutment block 106, and enabling the motor 103 to effectively transmit motion to the central shaft 105.

[0072] Example 3

[0073] A method of using a ventilation volume regulating device, employing a ventilation volume regulating device as described in Embodiment 1, includes the following steps:

[0074] a. Adjust the air volume

[0075] The controller 121 controls the start motor 103, which drives the central shaft 105 to rotate, thereby driving the adjusting plate 107 to rotate. When the adjusting plate 107 rotates to the appropriate position, the motor 103 is stopped, and the air in the pipe 102 can flow out through the gap between the adjusting plate 107 and the pipe 102, thus completing the control of the air volume.

[0076] The wind speed sensor 108 measures the airflow speed on both sides of the regulating plate 107 inside the pipe 102 in real time and transmits the speed value to the controller 121 to obtain the corresponding airflow. When the airflow is insufficient, the controller 121 controls the motor 103 to drive the regulating plate 107 to rotate, changing the angle of the regulating plate 107 inside the pipe 102, thereby adjusting the airflow inside the pipe 102.

[0077] b. Replace the motor

[0078] To remove the motor, first adjust the positions of the first abutment block 104 and the second abutment block 106 so that the contact surfaces of the first abutment block 104 and the second abutment block 106 are parallel to the screw 109. Then rotate the rotating disks on both sides to drive the screw 109 to rotate. Through the transmission of the rack 112, the moving block 110 is driven to move outward, thereby driving the motor 103 and the sealing body 113 to move outward within the U-shaped body 111, and finally remove them to remove the motor 103.

[0079] To install the motor, first place the motor 103 at the front end of the sealing body 113, and then move the motor 103 and the sealing body 113 together into the U-shaped body 111 until the rack 112 meshes with the screw 109. Then, rotate the rotating disk in the opposite direction. Through the transmission of the screw 109 and the rack 112, the moving block 110 is driven to move inward, while the sealing body 113 is pushed into the U-shaped body 111 until the first abutment block 104 on the motor 103 meshes with the second abutment block 106, thus completing the installation of the motor 103.

[0080] Example 4

[0081] A method of using a ventilation volume regulating device, applying a ventilation volume regulating device as described in Embodiment 2, includes the following steps:

[0082] a. Adjust the air volume

[0083] The controller 121 controls the start motor 103, which drives the central shaft 105 to rotate, thereby driving the adjusting plate 107 to rotate. When the adjusting plate 107 rotates to the appropriate position, the motor 103 is stopped, and the air in the pipe 102 can flow out through the gap between the adjusting plate 107 and the pipe 102, thus completing the control of the air volume.

[0084] The wind speed sensor 108 measures the airflow speed on both sides of the regulating plate 107 inside the pipe 102 in real time and transmits the speed value to the controller 121 to obtain the corresponding airflow. When the airflow is insufficient, the controller 121 controls the motor 103 to drive the regulating plate 107 to rotate, changing the angle of the regulating plate 107 inside the pipe 102, thereby adjusting the airflow inside the pipe 102.

[0085] b. Replace the motor

[0086] Remove the motor, first adjust the positions of the first abutment block 104 and the second abutment block 106 so that the contact surfaces of the first abutment block 104 and the second abutment block 106 are parallel to the screw 109, move the slider 205 to move the fixing rod 206 out of the slot of the sealing body 113, and remove the sealing body 113 through the handle 202. Then rotate the rotating disks on both sides to drive the screw 109 to rotate, and drive the moving block 110 to move outward through the transmission of the rack 112, and finally remove the motor 103.

[0087] To install the motor, first place the motor 103 at the front end of the sealing body 113, and then move the motor 103 and the sealing body 113 together into the U-shaped body 111 until the rack 112 engages with the screw 109. Then, rotate the rotating disk in the opposite direction. Through the transmission of the screw 109 and the rack 112, the moving block 110 is driven to move inward. At the same time, push the sealing body 113 into the U-shaped body 111 through the handle 202 until the first abutment block 104 on the motor 103 engages with the second abutment block 106. Then, move the slider 205 to move the fixing rod 206 into the slot of the sealing body 113, thus completing the installation of the motor 103.

[0088] The above content is only a preferred embodiment of the present invention. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of the present invention.

5. A method of using a ventilation volume regulating device, employing a ventilation volume regulating device as described in any one of claims 1 to 3, comprising the following steps: a. Adjust the air volume The controller starts the motor, which drives the central shaft to rotate, which in turn drives the adjusting plate to rotate. When the adjusting plate rotates to the appropriate position, the motor stops, and the air in the duct can flow out through the gap between the adjusting plate and the duct, thus controlling the air volume. The airflow speed on both sides of the regulating plate inside the duct is measured in real time by a wind speed sensor, and the speed value is transmitted to the controller to obtain the corresponding air volume. When the air volume is insufficient, the controller will control the motor to drive the regulating plate to rotate, change the angle of the regulating plate inside the duct, and thus adjust the air volume inside the duct. b. Replace the motor To remove the motor, first adjust the positions of the first and second abutting blocks so that the contact surfaces of the first and second abutting blocks are parallel to the screw. Then rotate the rotating discs on both sides to drive the screw to rotate. Through the transmission of the rack and pinion, the moving block moves outward, thereby driving the motor and the sealing body to move outward within the U-shaped body, and finally remove the motor. To install the motor, first place the motor at the front end of the sealing body, and then move the motor and the sealing body together into the U-shaped body until the rack and screw mesh. Then, rotate the rotating disk in the opposite direction. Through the transmission of the screw and rack, the moving block is driven to move inward, while pushing the sealing body into the U-shaped body until the first abutment block on the motor meshes with the second abutment block, thus completing the motor installation.

6. A method of using a ventilation volume regulating device, employing the ventilation volume regulating device as described in claim 4, comprising the following steps: a. Adjust the air volume The controller starts the motor, which drives the central shaft to rotate, which in turn drives the adjusting plate to rotate. When the adjusting plate rotates to the appropriate position, the motor stops, and the air in the duct can flow out through the gap between the adjusting plate and the duct, thus controlling the air volume. The airflow speed on both sides of the regulating plate inside the duct is measured in real time by a wind speed sensor, and the speed value is transmitted to the controller to obtain the corresponding air volume. When the air volume is insufficient, the controller will control the motor to drive the regulating plate to rotate, change the angle of the regulating plate inside the duct, and thus adjust the air volume inside the duct. b. Replace the motor Remove the motor, first adjust the positions of the first and second abutting blocks so that the contact surfaces of the first and second abutting blocks are parallel to the screw. Move the slider to move the fixing rod out of the slot of the sealing body, and remove the sealing body by the handle. Then rotate the rotating disks on both sides to drive the screw to rotate. Through the transmission of the rack and pinion, the moving block moves outward and finally the motor is removed. To install the motor, first place the motor at the front end of the sealing body, and then move the motor and the sealing body together into the U-shaped body until the rack and screw engage. Then, rotate the rotating disk in the opposite direction. Through the transmission of the screw and rack, the moving block moves inward. At the same time, push the sealing body into the U-shaped body with the handle until the first abutment block on the motor engages with the second abutment block. Then, move the slider to move the fixing rod into the slot of the sealing body, thus completing the installation of the motor.
