Description

Technical Field

[0001] The utility model belongs to the technical field of fuel use, and in particular relates to a transmission device for fuel use in thermal power plants. Background Art

[0002] Thermal power plant fuel generally refers to the fuel required for thermal power plants to produce electricity, including solid fuel, liquid fuel and gas fuel. During the use of solid fuel, it needs to be transported through a transmission device. Currently, the transmission device in thermal power plants is usually a transport cart.

[0003] In the prior art, a transmission device for fuel used in thermal power plants is disclosed with the patent announcement number CN2188807627U. In the above patent, the coal fuel is placed in a storage tank during use. When the staff needs to unload the coal fuel, they turn the rotating plate away from one side of the box body, leaving a discharge port, start the cylinder, and the cylinder lifts the lifting plate upward. Since the lifting plate is inclined, the coal fuel will follow the inclined surface and slowly flow out of the storage tank from one side of the rotating plate. For some coal fuel that has not flowed out and remains on the lifting plate, the motor is used to drive the threaded rod to rotate, and the threaded rod will push the plate. Movement, the limit plate is installed on the push plate, and the elastic force of the spring pushes the limit plate so that the limit plate is always close to the lifting plate, thereby pushing the coal fuel on the lifting plate out. However, there are still the following deficiencies in actual use: From a practical point of view, when the above-mentioned transport device is transported to the designated location for loading or unloading, the wheels set at the bottom can easily cause the entire device to move, affecting work efficiency, and due to the flatness of the ground, the trolley will vibrate, and the vibration can easily cause solid fuel particles such as coal to be broken, producing smaller particles, which not only increases the difficulty of fuel processing, but may also cause dust problems.

[0004] Therefore, a fuel transmission device for thermal power plants is needed to solve the problem in the prior art that when loading or unloading at a designated location, the wheels provided at the bottom easily cause the entire device to move, thereby affecting work efficiency.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-4The utility model provides a fuel transmission device for thermal power plants, including a base plate 1, wheels 2, a fixing mechanism 3, a push handle 4, a box body 5, a cover plate 6 and a buffer mechanism 7. The wheels 2 are symmetrically fixedly connected to the bottom surface of the base plate 1 around the periphery, the fixing mechanism 3 is symmetrically arranged below the left and right sides of the base plate 1, the push handle 4 is fixedly connected to the back side of the base plate 1, the buffer mechanism 7 is symmetrically arranged above the left and right sides inside the base plate 1, the box body 5 is arranged above the buffer mechanism 7, and the cover plate 6 is movably connected to the top of the box body 5.

[0024] The fixing mechanism 3 is composed of a motor 301, a bidirectional screw rod 302, a threaded block 303, a limit block 304, a connecting rod 305, a connecting seat 306, a guide rail 307, a fixing plate 308, a sliding rod 309 and a first spring 310. The front and rear sides of the base plate 1 are symmetrically provided with mounting grooves. The motor 301 is fixedly connected to the rear of the mounting groove. The bidirectional screw rod 302 is fixedly connected to the output end of the motor 301, and the bidirectional screw rod 302 is rotatably connected to the mounting groove. The threaded block 303 is symmetrically threadedly connected to the outside of the bidirectional screw rod 302. The connecting rod 305 is rotatably connected to the bottom of the threaded block 303, and the connecting seat 306 is rotatably connected to the bottom end of the connecting rod 305.

[0025] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the limit blocks 304 are symmetrically fixedly connected to the left and right sides of the threaded block 303, and the interior of the mounting groove is symmetrically provided with limit grooves adapted to the limit blocks 304;

[0026] Due to the thread design of the bidirectional screw rod 302, when the bidirectional screw rod 302 rotates, the limit block 304 slides inside the limit groove, limiting the thread block 303 from rotating with the limit block 304, ensuring that the thread block 303 can stably perform left and right linear motion.

[0027] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that through holes are symmetrically opened on the front and back sides of the installation groove, the slide rod 309 is slidably connected to the inside of the through hole, the fixed plate 308 is fixedly connected to the bottom surface of the slide rod 309, and the guide rail 307 is fixedly connected to the upper middle part of the fixed plate 308.

[0028] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the connecting seat 306 is slidably connected to the outside of the guide rail 307, the first spring 310 is fixedly connected between the bottom surface of the base plate 1 and the fixed plate 308, and the first spring 310 is sleeved on the outside of the slide rod 309;

[0029] The first spring 310 plays a role of buffering and stabilizing when the fixing plate 308 moves downward, thereby preventing the fixing plate 308 from suddenly hitting the ground and causing damage.

[0030] According to the above working process, it can be seen that: through the provided wheels 2 and fixing mechanism 3, the entire device and the internal fuel can be driven for movement and transportation by the wheels 2, and the entire device can be fixed to the ground through the fixing plate 308 during loading and unloading to prevent the device from moving, thereby improving the flexibility, stability and work efficiency of the device during use.

[0031] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the buffer mechanism 7 is composed of a fixed rod 701, a moving block 702, a second spring 703, a rotating rod 704, a connecting block 705 and a shock absorbing assembly 706. The top surface of the base plate 1 is symmetrically provided with grooves, the fixed rod 701 is fixedly connected to the inside of the groove, the moving block 702 is symmetrically slidably connected to the outside of the fixed rod 701, the second spring 703 is fixedly connected between the moving blocks 702, and the second spring 703 is sleeved on the outside of the fixed rod 701.

[0032] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the rotating rod 704 is rotatably connected to the top of the moving block 702, the connecting block 705 is rotatably connected to the top of the rotating rod 704, and the connecting block 705 is fixedly connected to the bottom surface of the box body 5.

[0033] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the shock absorbing assembly 706 is symmetrically arranged between the box body 5 and the middle part of the bottom plate 1, and the shock absorbing assembly 706 is symmetrically arranged on the left and right, and the shock absorbing assembly 706 includes a shock absorbing spring and a damper;

[0034] The shock absorbing components 706 provided play an important role in buffering. They can further absorb and disperse vibration and impact force, ensuring that the fuel inside the tank 5 remains stable and safe during movement.

[0035] This solution has the following working process: when in use, the wheel 2 at the bottom drives the entire device to move to the loading position, and then the motor 301 is started to drive the bidirectional screw rod 302 to rotate inside the installation groove, and the threaded block 303 moves toward each other, thereby driving the connecting rod 305 to rotate accordingly, driving the connecting seat 306 to slide and connect to the guide rail 307, so that the fixed plate 308 moves downward, and at the same time, the sliding rod 309 follows the fixed plate 308 to move downward, and the sliding rod 309 slides inside the through hole. When the fixed plate 308 contacts the ground and generates sufficient friction, the entire device is fixed. Plate 308 is fixed to the ground to ensure the stability of the entire device during the loading or unloading process; then the cover plate 6 is opened and the material is loaded into the interior of the box body 5. After loading is completed, the cover plate 6 is closed and the fixed plate 308 is driven upward by controlling the reverse rotation of the motor 301, so that the device moves through the wheels 2 on the bottom surface. During the movement, when encountering uneven roads or obstacles, vibrations and impact forces will be generated, first acting on the connecting block 705. Since the connecting block 705 is fixedly connected to the bottom surface of the box body 5, the vibrations and impact forces will be transmitted to the rotating rod 704 and the moving block 702. The moving block 702 slides along the fixed rod 701 and compresses or stretches the second spring 703. The second spring 703 plays a key buffering role in this process. It can absorb and disperse vibrations and impact forces, reducing the direct impact of these forces on the fuel inside the box body 5. At the same time, the shock absorbing assembly 706 (including shock absorbing springs and dampers) also plays an important buffering role. They can further absorb and disperse vibration and impact force, ensuring that the fuel inside the box body 5 remains stable and safe during movement. The provided cover plate 6 prevents the fuel from generating dust and affecting the surrounding environment, thereby improving the stability and safety of the fuel inside the box body 5 and preventing damage or leakage caused by vibration and impact force.

[0036] In summary: through the provided wheels 2 and fixing mechanism 3, the entire device and the internal fuel can be moved and transported by the wheels 2, and the entire device can be fixed to the ground by the fixing plate 308 during loading and unloading to prevent the device from moving, thereby improving the flexibility, stability and working efficiency of the device during use; through the provided buffer mechanism 7, when encountering uneven roads or obstacles during movement, the stability and safety of the fuel inside the box 5 are improved to prevent damage or leakage caused by vibration and impact force, and the provided cover plate 6 can prevent the fuel from generating dust and affecting the surrounding environment.
