[0002] Thermal power plant fuel generally refers to the fuel required for electricity production in thermal power plants, including solid fuel, liquid fuel, and gaseous fuel. Solid fuel needs to be transported through transmission devices during its use. Common transmission devices include transfer vehicles and belt conveyors.

[0003] In the operation of belt conveyors, solid fuel is transported from coal conveying pipes onto the belt conveyor and then conveyed to a designated area.

At the point of impact, the belt is directly subjected to the impact of the falling material, resulting in faster wear and affecting its service life. Therefore, to solve this problem, we propose a conveying device for fuel use in thermal power plants. Summary of the Invention

[0035] Example 1

[0036] Reference Figures 1 to 8This is the first embodiment of the present invention, which provides a transmission device for fuel use in thermal power plants. The device includes a support unit 100, including a base component 101, a support bed 102 disposed on the side of the base component 101, multiple sets of supporting components 103 disposed on the support bed 102, drive wheels 104 symmetrically disposed at both ends of the support bed 102, and a transmission belt 105 sleeved on the two sets of drive wheels 104. The transmission belt 105 is a conveyor belt structure, which can perform fuel transmission work by being driven by the drive wheels 104.

[0037] The conveying unit 200 includes a conveying component 201 located above the base component 101, and four sets of spiral guide vanes 202 disposed inside the conveying component 201, with the four sets of spiral guide vanes 202 arranged alternately in a spiral manner, and a clearance groove 203 formed between every two sets of spiral guide vanes 202; the conveying component 201 is a feeding channel for conveying fuel, which can change the vertically falling fuel into a spiral movement for conveying, avoiding direct impact on the transmission belt 105;

[0038] The drive unit 300 includes a drive motor 301 located at the center of the bottom end of the conveying component 201, a drive component 302 disposed above the drive motor 301 and extending upward to the axis of the conveying component 201, a connecting shaft 303 disposed at the top end of the drive component 302, and multiple sets of limiting rings 304 evenly distributed on the drive component 302; the drive motor 301 can drive the drive component 302 to rotate, thereby driving the material feeding unit 400 to perform agitation and unblocking operations; and...

[0039] The material feeding unit 400 includes a material feeding assembly 401 sleeved on the drive component 302 and located between the limiting rings 304, two sets of actuating frames 402 symmetrically arranged on the material feeding assembly 401, an abutting component 403 located between the two sets of actuating frames 402, and a tightening component 404 located below the material feeding assembly 401. The position and number of the material feeding units 400 correspond to and match the clearance grooves 203. This device has a total of three sets of material feeding units 400, which are evenly distributed in the conveying component 201. The drive component 302 can drive the material feeding units 400 to perform circumferential displacement, thereby achieving the purpose of pushing and clearing within the conveying unit 200.

[0040] The base component 101 includes two sets of base plates 101a located on both sides below the conveying component 201, a transmission chamber 101b opened inside the base plate 101a, a transition plate 101c disposed on the side of the transmission chamber 101b, and a protective frame 101d disposed on the other side above the transmission chamber 101b. The transition plate 101c has a wedge-shaped structure, and its inclined edge extends to directly above the transmission belt 105.

[0041] During use, the conveyor belt 105 divides the conveyor bin 101b into upper and lower groups. The upper conveyor bin 101b is used to hold the coal falling from above. A portion of the protective frame 101d extends from one side and is fixedly connected to the side of the base component 101. The protective frame 101d has a conical structure. The conical structure can reduce the resistance when conveying solid fuel. The drive motor 301 is installed inside the conical structure.

[0042] The supporting component 103 includes a bottom roller 103a located above the support bed 102, a fixing block 103b disposed on both sides of the bottom roller 103a and fixedly connected to the support bed 102, and a side roller 103c inserted into the outside of the fixing block 103b in an inclined state.

[0043] During use, the side rollers 103c are rotatably connected to both sides of the bottom rollers 103a, and the bottom rollers 103a are rotatably connected between two sets of fixed blocks 103b. The support component 103 as a whole can form a U-shaped structure when viewed from the side. When the conveyor belt 105 runs on the support component 103, the side rollers 103c on both sides can lift the sides of the conveyor belt 105, so that the conveyor belt 105 forms a side-lifted structure. The fuel piled on the conveyor belt 105 for transportation will be lifted from both sides and gathered inward, thereby preventing the fuel from falling from the conveyor belt 105 to the sides of the device during the transmission process.

[0044] Example 2

[0045] Reference Figures 5-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a spiral guide plate 202 is used to guide the movement trajectory of solid fuel during the transmission process, reduce the impact force when it falls, and thus reduce the burden on the conveyor belt and extend its service life.

[0046] Compared to Embodiment 1, the conveying component 201 further includes a conveying barrel 201a located above the base component 101, a feed hopper 201b disposed at the top of the conveying barrel 201a, a feed channel 201c opened in the conveying barrel 201a, and a fixing rod 201d disposed on the inner side of the top of the feed channel 201c. The conveying barrel 201a is connected to the feed hopper 201b, the fixing rod 201d is fixedly connected to the conveying component 201, and the connecting shaft 303 extends into the fixing rod 201d, forming a rotatable connection.

[0047] Among them, the upper and lower surfaces of the spiral guide plate 202 are the top surface 202a and the bottom surface 202b, respectively. The two ends of the spiral guide plate 202 are the high end 202c and the low end 202d, respectively. The horizontal height of the high end 202c is greater than that of the low end 202d. The overall direction of the spiral guide plate 202 is a spiral twist from the high end 202c to the low end 202d. The high end 202c and the low end 202d of every two sets of spiral guide plates 202 are close to each other and have the same spiral direction.

[0048] Furthermore, due to the special structure of the spiral guide plate 202, when the spiral guide plate 202 is installed inside the conveying component 201, it will divide the feed channel 201c into a spiral conveying channel inside it. The feed end of the conveying pipe is located above the feed channel 201c and is called the feed port 201e. The outlet below it is the discharge port 201f. The opening of the discharge port 201f faces the inclined surface directly opposite the adapter plate 101c. Therefore, the fuel discharged by the spiral guide plate 202 will be guided by the discharge port 201f and fall onto the adapter plate 101c immediately, instead of falling onto the conveyor belt 105, thereby further absorbing the impact force.

[0049] During operation, when fuel enters the feed channel 201c through the feed inlet 201e, it moves and falls along the spiral guide plates 202. Multiple sets of spiral guide plates 202 extend the path length of the fuel's descent within the conveying unit 200, thus prolonging its descent time and gradually reducing the impact force of the falling fuel, thereby reducing the peak impact force. Simultaneously, with the cooperation of multiple sets of spiral guide plates 202, the fuel's descent is not a one-time impact, but rather distributed at various points along the spiral path. Therefore, the impact force is dispersed and mitigated. Similarly, due to the increased movement distance of the fuel within the conveying unit 200... Furthermore, the contact time and contact area between the material and the top surface 202a of the multiple sets of spiral guide plates 202 will also increase, thereby increasing the friction between the object and the spiral guide plates 202, hindering the descent speed of the object, further reducing the impact force. Finally, the material is guided and discharged through the discharge port 201f, impacting the discharge port 201f. The discharge port 201f can further absorb the fuel after the impact force has been eliminated, and then guide the fuel to the transmission belt 105. At this time, the impact force of the fuel falling onto the transmission belt 105 has been greatly reduced, thereby effectively extending its service life.

[0050] The remaining structure is the same as that in Example 1.

[0051] Example 3

[0052] Reference Figures 7-10This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the solid fuel running in the conveying unit 200 is pushed and agitated to clear the channel and prevent the channel from being blocked.

[0053] Compared to Embodiment 2, the driving component 302 further includes a rotating shaft 302a coaxial with the conveying component 201 in the vertical direction, a side receiving groove 302b opened on the outside of the rotating shaft 302a, an engaging block 302c disposed in the side receiving groove 302b, and a support spring 302d located between the side receiving groove 302b and the engaging block 302c. One end of the engaging block 302c is rotatably connected to the rotating shaft 302a. The support spring 302d can be pushed outward by elastic support, and when squeezed, it will contract inward and drive the engaging block 302c to retract back into the side receiving groove 302b.

[0054] The feeding assembly 401 includes a collar 401a sleeved on the drive component 302, teeth 401b disposed inside the collar 401a, a lever 401c disposed on one outer end of the collar 401a, side sliding grooves 401d opened on the front and rear sides of the lever 401c, and a cross-shaped storage groove 401e opened vertically in the lever 401c. The width of the lever 401c matches the clearance groove 203, so the lever 401c can pass through the clearance groove 203. The size of the cross-shaped storage groove 401e matches the actuation frame 402 and the abutment component 403 to provide space for storing both. The teeth 401b are obliquely arranged, and their inner sides abut against the outer end of the meshing block 302c.

[0055] During use, the support spring 302d pushes out the engagement block 302c through elastic support. The top of the pushed-out engagement block 302c will engage with the teeth 401b. At this time, the drive component 302 engages with the collar 401a through the engagement block 302c. Therefore, the rotation of the drive component 302 can drive the feeding component 401 to rotate synchronously. The rotating feeding component 401 can push the fuel that slides on the spiral guide plate 202 to prevent it from staying and blocking the feed channel 201c, thus playing a role in clearing and protecting.

[0056] The actuating frame 402 includes a support rod 402a located in the cross-shaped storage groove 401e, and limiting shafts 402b symmetrically arranged at both ends of the support rod 402a. The limiting shaft 402b located at the end of the support rod 402a extends into the side sliding groove 401d. The top end of the support rod 402a is rotatably connected to the abutment member 403. The limiting shaft 402b extends into the side sliding groove 401d and can slide horizontally along the side sliding groove 401d.

[0057] The abutting component 403 includes a roller 403a located between two sets of actuating brackets 402, and connecting ears 403b symmetrically arranged on both sides of the roller 403a. The roller 403a and the connecting ears 403b are rotatably connected.

[0058] The tightening component 404 includes a sleeve 404a located below the lever 401c, an extension rod 404b disposed on one side of the sleeve 404a, a spring groove 404c opened inside the sleeve 404a and one end of the extension rod 404b extending into the spring groove 404c, a contraction spring 404d disposed between the sleeve 404a and the extension rod 404b and the contraction spring 404d located in the spring groove 404c, and a rotating ear 404e disposed at both the end of the sleeve 404a and the beginning of the extension rod 404b. The two ends of the feeding unit 400 are rotatably sleeved on the limiting shaft 402b through the rotating ear 404e. The 403c always applies a contraction force inward, so the sleeve 404a and the extension rod 404b are pulled by it and always move relative to each other.

[0059] During use, when the drive component 302 drives the feeding unit 400 to rotate as a whole through the feeding assembly 401, the tightening component 404 will be pulled inward by the contraction of the spring groove 404c, and the sleeve 404a and extension rod 404b will pull the two sides of the feeding frame 402 inward. The two sets of relatively moving feeding frames 402 will push the abutment component 403 upward, thus forming a triangular support structure. The triangular structure can increase the contact area between the feeding unit 400 and the fuel, thereby pushing more fuel and enhancing the pushing and unblocking efficiency. As the feeding unit 400 gradually... As the unit rotates, the contact part 403 gradually comes into contact with the bottom surface 202b. Due to the compression and guidance of the bottom surface 202b, the contact part 403 gradually presses down on the two sides of the actuating frame 402, and finally causes the actuating frame 402 and the contact part 403 to retract into the cross-shaped storage groove 401e. The retracted material feeding unit 400 has a long strip structure, which can pass perfectly through the clearance groove 203. The clearance groove 203 provides clearance for the circumferential rotation of the material feeding unit 400, thereby enabling the material feeding unit 400 to perform cyclic pushing and unblocking work in the conveying unit 200.

[0060] The remaining structure is the same as that in Example 2.
