Description

Technical Field

[0001] This utility model belongs to the field of trash racks, and specifically relates to a new type of trash rack. Background Technology

[0002] A trash rack, installed before the water inlet, is a frame structure used to block debris such as aquatic plants and driftwood carried by the water flow. To promptly clean the debris intercepted by the trash rack, a cleaning mechanism is often used in conjunction with it. The cleaning mechanism removes debris attached to the trash rack and is commonly used in reservoirs or rivers with high levels of debris to ensure the safe and normal operation of hydropower stations or pumping stations. It can perform cleaning without shutting down the system or emptying the reservoir. However, when traditional trash racks and cleaning mechanisms are used together, they often use chains to connect the shafts at both ends of the cleaning mechanism for cyclical drive. When lifting the intercepted debris, the force is all applied to the chain, which results in poor load-bearing capacity and susceptibility to damage when there is a lot of debris. In addition, the grid structure of traditional trash racks is relatively fixed and components are connected by welding. The welded points result in poor corrosion and rust resistance, affecting the structural stability of the equipment in subsequent use, and making repair and replacement inconvenient when parts are damaged. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To overcome the shortcomings of existing technologies, a new type of trash rack is proposed. This addresses the problem that traditional trash racks and cleaning mechanisms often use chains to connect the shafts at both ends of the cleaning mechanism for cyclical drive. When intercepting and lifting trash, the force is all applied to the chain, resulting in poor load-bearing capacity and susceptibility to damage when there is a large amount of trash. In addition, the traditional trash rack has a relatively fixed grid structure and uses welding to connect components. The welded points result in poor corrosion and rust resistance, affecting the structural stability of the equipment in subsequent use, and making repair and replacement inconvenient when parts are damaged.

[0005] (II) Technical Solution

[0006] This utility model is achieved through the following technical solution: This utility model proposes a novel trash rack, the structure of which includes a support frame, a trash racking mechanism and a power source. The trash racking mechanism is obliquely mounted on the support frame, and the power source is used to drive the trash racking mechanism to operate.

[0007] The debris-blocking mechanism includes claw rods, side plates, combined plates, separator tubes, drive separator tubes, drive wheels, combined rods, shafts, and limiting rods. The combined plates, separator tubes, and drive separator tubes are all sleeved and assembled on the combined rods. Each or more of the combined plates form a group. Each group of combined plates is separated by separator tubes or drive separator tubes. The combined plates, separator tubes, or drive separator tubes at the edges of the combined rods are limited by limiting structures. Two adjacent combined rods are connected by combined plates. Multiple combined rods are connected by combined plates to form an annular grid.

[0008] The two side plates are fixed to the support frame at a mirror angle. A shaft is embedded on both sides between the two side plates. One side of the upper shaft passes through the side plate and is connected to the power source. One or more drive wheels are covered and fixed on the shaft. The drive wheels drive the grid to move in a cycle by engaging with the drive tube on each of the combined rods. Both sides of the combined rod are embedded in the side plates. The side plates are used to limit the movement of the combined rod on both sides. One end of the claw rod is fixed vertically to the side end face of the partition tube. A limit rod is fixed on the side of the combined plate, partition tube, or drive tube adjacent to the claw rod. The limit rod is used to limit the angle of downward flip when the claw rod moves upward.

[0009] Furthermore, both ends of the combined plate are provided with combined holes, and the combined plate is fitted onto the combined rod through the combined holes. The diameter of the combined holes is greater than or equal to the diameter of the combined rod.

[0010] Furthermore, the claw bar has a bent structure on the side away from the separator tube. The bent structure is tilted upwards towards the side away from the separator tube when the claw bar moves upwards, which facilitates the lifting of the intercepted dirt by the claw bar and reduces the possibility of dirt slipping off the claw bar.

[0011] Furthermore, the middle of the separator tube has a through first hole, the diameter of which is greater than or equal to the maximum diameter of the combined rod, and the maximum diameter of the separator tube is greater than the maximum diameter of the combined hole.

[0012] Furthermore, the middle of the drive tube is a through second tube hole, the diameter of the second tube hole is greater than or equal to the maximum diameter of the combined rod, the maximum diameter of the drive tube is greater than the maximum diameter of the combined hole, and a first engagement groove is provided around the side end face of the drive tube. The first engagement groove is a groove that gradually deepens towards the center, which facilitates the alignment, engagement and positioning of the first engagement groove.

[0013] Furthermore, the debris-blocking mechanism also includes a positioning rod and a positioning assembly rod. The positioning rod is assembled within the circulating grid area via the positioning assembly rod. The positioning rod is used for positioning and limiting the drive tube when the grid moves cyclically. The side end face of the positioning rod is a protruding structure that fits into the first meshing groove. Combined with the groove structure that gradually deepens towards the center of the first meshing groove, the drive tube can better maintain its position when moving, thus facilitating more accurate engagement with the drive wheel and preventing jamming or collisions caused by the drive tube shifting during cyclic movement and failing to engage accurately with the drive wheel.

[0014] Furthermore, the limiting structure consists of a pin and limiting holes extending through both sides of the combined rod. The pin is Ω-shaped and made of a metal with a certain degree of toughness. The pin is inserted into the limiting hole to limit the combined plate, partition tube, or drive tube at the edge of the combined rod, so that the limiting and fixing of the combined plate, partition tube, and drive tube on the combined rod can be quickly released or fixed by pulling out the pin.

[0015] Furthermore, the side plate is provided with a circulation limiting groove adjacent to the combined rod. The circulation limiting groove is an annular groove that is consistent with the circulation trajectory of the combined rod, and the width of the circulation limiting groove is greater than or equal to the maximum diameter of the combined rod.

[0016] Furthermore, the side plate is provided with bearings and shaft grooves on both sides near the combined rod, and the shaft is assembled in the shaft groove through the bearings.

[0017] Furthermore, the portion of the combined rod located within the cyclic limiting groove may also be fitted with a bearing.

[0018] Furthermore, a plurality of second engagement grooves are uniformly provided on the side end face of the drive wheel. The thickness of the drive wheel is less than the length of the partition tube and the drive partition tube, so that the drive wheel can pass between the combined plates separated by the partition tube or the drive partition tube. The second engagement groove is used to engage with the first engagement groove.

[0019] Furthermore, the support frame is equipped with a conveyor belt on the opposite side of the direction of the waste flow, and the conveyor belt is used to automatically transport and discharge the waste intercepted by the waste interception mechanism.

[0020] Furthermore, the claw rod, side plate, combination plate, partition tube, drive partition tube, drive wheel, combination rod, shaft rod and limit rod are all made of metal materials and their surfaces are treated with anti-corrosion and anti-rust treatment.

[0021] Furthermore, the power source is an electric motor, a motor with a gearbox, a motor with a coupling, or other equipment capable of driving the shaft to rotate.

[0022] (III) Beneficial Effects

[0023] One of the above technical solutions has the following advantages or beneficial effects:

[0024] 1. A grid structure is formed by connecting combined plates and partition tubes or drive tubes to combined rods, and connecting adjacent combined rods through combined plates. Limiting structures are used on both sides of the combined rods to limit the combined plates, and the movement is further limited by side plates on both sides of the combined rods. This achieves a weld-free splicing structure, avoiding the impact of welds on the corrosion and rust prevention performance of the equipment while ensuring the structural stability of the equipment for long-term use. At the same time, when part of the equipment structure is damaged, the combined components can be quickly replaced individually by releasing the limiting of the combined plates, which facilitates maintenance and reduces maintenance costs.

[0025] 2. By installing drive wheels on the shaft, the drive wheels sequentially engage with the drive tubes on each combined rod to drive the grid structure in a cyclical movement. This ensures that the force applied when the equipment lifts debris is concentrated on the drive tubes and combined rods. Since the combined rods are connected by combined plates, the force on the combined rods is distributed throughout the entire debris-blocking mechanism, resulting in better load-bearing capacity and easier debris removal. Additionally, the number of combined plates in each group can be adjusted to increase the load-bearing capacity. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0040] This utility model provides a novel trash rack: its structure includes a support frame 1, a trash-blocking mechanism 2 and a power source 3, wherein the trash-blocking mechanism 2 is obliquely mounted on the support frame 1, and the power source 3 is used to drive the trash-blocking mechanism 2 to operate;

[0041] The debris-blocking mechanism 2 includes a claw rod 201, a side plate 202, a combined plate 203, a separator tube 204, a drive separator tube 205, a drive wheel 206, a combined rod 207, a shaft 208, and a limiting rod 211. The combined plate 203, separator tube 204, and drive separator tube 205 are all sleeved onto the combined rod 207. Every three combined plates 203 form a group, and each group of combined plates 203 is separated by a separator tube 204 or a drive separator tube 205. The combined plate 203 at the edge of the combined rod 207... 3 or the partition tube 204 or the drive partition tube 205 are limited by the limiting structure. Two adjacent combined rods 207 are connected by the combined plate 203. The combined plate 203 in the middle part and the combined plate 203 on both sides of each group are respectively connected to two different adjacent combined rods 207. The combined plates 203 in adjacent groups are staggered and connected to the same combined rod 207 by the combined plate 203 in the middle part and the combined plate 203 on both sides. Multiple combined rods 207 are connected by the combined plate 203 to form an annular grid.

[0042] Two side plates 202 are fixed to the support frame 1 at a mirror angle. A shaft 208 is embedded on both sides between the two side plates 202. One side of the upper shaft 208 passes through the side plate 202 and is connected to the power source 3. One or more drive wheels 206 are covered and fixed on the shaft 208. The drive wheels 206 drive the grid to move in a cycle by engaging with the drive tube 205 on each of the combined rods 207. Both sides of the combined rods 207 are embedded in the side plates 202. The side plates 202 are used to limit the movement of the combined rods 207 on both sides. One end of the claw rod 201 is vertically fixed to the side end face of the partition tube 204. A limit rod 211 is fixed on the side of the combined plate 203, partition tube 204, or drive tube 205 adjacent to the claw rod 201. The limit rod 211 is used to limit the angle of downward flipping when the claw rod 201 moves upward.

[0043] The combined plate 203 has a combined hole 20301 through both ends. The combined plate 203 is fitted onto the combined rod 207 through the combined hole 20301. The diameter of the combined hole 20301 is greater than or equal to the diameter of the combined rod 207.

[0044] The partition tube 204 has a through first hole 20401 in the middle, the diameter of the first hole 20401 is greater than or equal to the maximum diameter of the combined rod 207, and the maximum diameter of the partition tube 204 is greater than the maximum diameter of the combined hole 20301.

[0045] The drive tube 205 has the same structure as the partition tube 204.

[0046] The side plate 202 is provided with a circulation limiting groove 212 adjacent to the combined rod 207. The circulation limiting groove 212 is an annular groove that is consistent with the circulation trajectory of the combined rod 207. The width of the circulation limiting groove 212 is greater than or equal to the maximum diameter of the combined rod 207.

[0047] Among them, the side plate 202 is provided with bearings 20201 and shaft grooves 20202 on both sides near the combined rod 207, and the shaft 208 is assembled in the shaft groove 20202 through the bearings 20201.

[0048] The portion of the combined rod 207 located within the circulatory limiting groove 212 may also be equipped with a bearing 20201.

[0049] The claw rod 201, side plate 202, combined plate 203, partition tube 204, drive partition tube 205, drive wheel 206, combined rod 207, shaft rod 208 and limiting rod 211 are all made of metal materials and their surfaces are treated with anti-corrosion and anti-rust treatment.

[0050] The power source 3 is a motor, a motor with a gearbox, a motor with a coupling, or other equipment that can drive the shaft to rotate.

[0051] In use, the power source 3 drives the upper shaft 208 of the debris-blocking mechanism 2 to rotate, which in turn drives the drive wheel 206 to rotate. When the drive wheel 206 rotates, it moves by engaging the drive partition 205, which in turn drives the combined rod 207 and the combined plate 203 and the partition tube 204 on the same rod to move together. When one combined rod 207 moves, it will drive the other combined rods 207 to move together through the side plate 202, thereby realizing the cyclic movement of the combined grid structure. When the combined rod 207 moves, its side is limited by the side plate 202 to prevent the combined rod from shifting to the side at will.

[0052] As the combined rod 207 moves, the claw rod 201 mounted on the separator tube 204 also moves. When the claw rod 201 moves to the bottom of the debris-blocking mechanism 2, it will drop to its lowest point due to gravity. Then, as the claw rod 201 rises with the grid, it will scoop up the debris from the bottom. At this time, the debris will push the claw rod 201 to flip. After the claw rod 201 flips to a certain angle, it will be blocked and limited by the limit rod 211 to prevent the claw rod 201 from flipping too much and causing the debris to slip. After the claw rod 201 passes the highest point of the debris-blocking mechanism 2, the debris on the claw rod 201 will fall and be discharged due to gravity. The claw rod 201, due to the discharge of debris and the drop due to gravity, avoids the claw rod 201 opening at a fixed angle and causing the debris to fall back, or causing the claw rod 201 to be bumped and endangering the staff.

[0053] When some components of the equipment are damaged, the damaged parts can be disassembled and replaced individually to reduce maintenance costs. At the same time, the equipment adopts a weld-free splicing structure, avoiding the impact of welds on the anti-corrosion and anti-rust performance of the equipment and ensuring the structural stability of the equipment for long-term use. When the equipment lifts sewage, the force is also applied to the drive baffle 205 and the combined rod 207. Since the combined rods 207 are connected by combined plates 203, the force of the combined rods 207 is distributed to the entire sewage blocking mechanism 2, so that the load-bearing capacity of the equipment is better and the sewage is easier to clean. At the same time, the number of combined plates 203 in each group can be adjusted to increase the load-bearing capacity. For example, in this embodiment, three combined plates 203 are used in each group. The adjacent combined rods 207 are connected by alternating single and double plates, which can improve the load-bearing capacity and reduce the amount of materials used.

[0054] Finally, the equipment adopts a design in which the partition tube 204 and the drive partition tube 205 are sleeved on the combined rod 207, so that the combined rod 207 can rotate relative to the partition tube 204 and the drive partition tube 205, thereby making the combined plate 203 rotate more smoothly. At the same time, when the drive partition tube 205 is driven to rotate by the drive wheel 206, it can drive the combined rod 207 to rotate cyclically more smoothly through relative rotation.

[0055] Example 2:

[0056] like Figure 1 , 2 As shown in Figure 7, compared to Embodiment 1, the claw bar 201 in this embodiment has a bent structure on the side away from the separator tube 204. The bent structure is tilted upwards towards the side away from the separator tube 204 when the claw bar 201 moves upwards. Compared to the embodiment, the dirt that is more easily intercepted is lifted by the claw bar 201, further reducing the situation where dirt slips off the claw bar 201. The rest of the structure and the achieved effect remain unchanged.

[0057] Example 3:

[0058] like Figure 2 , Figure 8 and Figure 9 As shown, compared to the previous embodiment, the driving partition tube 205 in this embodiment has a through second tube hole 20502 in the middle. The diameter of the second tube hole 20502 is greater than or equal to the maximum diameter of the combined rod 207. The maximum diameter of the driving partition tube 205 is greater than the maximum diameter of the combined hole 20301. A first engagement groove 20501 is provided around the side end face of the driving partition tube 205. The first engagement groove 20501 is a groove that gradually deepens towards the center.

[0059] The debris-blocking mechanism 2 further includes a positioning rod 209 and a positioning assembly rod 210. The positioning rod 209 is assembled within the circulating grid area via the positioning assembly rod 210. The positioning rod 209 is used to position and limit the partition tube 205 when the grid moves cyclically. The side end face of the positioning rod 209 is a protruding structure that fits into the first meshing groove 20501.

[0060] The drive wheel 206 has a plurality of second engagement grooves 20601 evenly provided on its side end face. The thickness of the drive wheel 206 is less than the length of the partition tube 204 and the drive partition tube 205, so that the drive wheel 206 can pass between the combined plates 203 separated by the partition tube 204 or the drive partition tube 205. The second engagement groove 20601 is used to engage with the first engagement groove 20501.

[0061] Compared to the previous embodiments, the first engagement groove 20501 in this embodiment is more convenient for alignment, engagement, and positioning. The design of the positioning rod 209, and the protruding structure design of the side end face of the positioning rod 209 that fits with the first engagement groove 20501, allows the driving tube 205 to be positioned and limited by the positioning rod 209 when moving, so that the driving tube 205 can better maintain its position, thereby facilitating precise engagement with the driving wheel 206 later. This prevents jamming or collisions caused by the driving tube 205 shifting during cyclic movement and failing to engage accurately with the driving wheel 206. The design of the grooved second engagement groove 20601 on the driving wheel 206 allows the driving tube 205 to be wrapped inside the second engagement groove 20601 when the driving wheel 206 engages with the driving tube 205, facilitating stable rotation of the combined rod 207 through the driving tube 205. The rest of the structure and the achieved effect remain unchanged.

[0062] Example 4:

[0063] like Figure 10 As shown, compared to the previous embodiment, the limiting structure in this embodiment is a pin 20702 and limiting holes 20701 that penetrate both sides of the combined rod 207. The pin 20702 is Ω-shaped and made of metal with a certain degree of toughness. The pin 20702 is inserted into the limiting hole 20701 to limit the combined plate 203, the partition tube 204, or the drive partition tube 205 at the edge of the combined rod 207. Compared to the previous embodiment, this embodiment allows for quick pin fixing or removal of the pin 20702 within the limiting hole 20701 of the combined rod 207 due to its Ω shape and toughness. This allows the limiting fixing of the combined plate 203, the partition tube 204, and the drive partition tube 205 on the combined rod 207 to be quickly released or fixed by removing the pin 20702. The remaining structure and the achieved effect remain unchanged.

[0064] Example 5:

[0065] like Figure 11 As shown, compared to the previous embodiment, the support frame 1 in this embodiment is equipped with a conveyor belt 4 on the opposite side of the direction of the dirt coming from. After the claw bar 201 passes the highest point of the dirt blocking mechanism 2, the dirt on the claw bar 201 will fall onto the conveyor belt 4 due to gravity for automatic conveying and discharge. Because of the discharge of dirt and the falling due to gravity, the claw bar 201 will not collide with the conveyor belt 4, which is convenient for automatic cleaning. The rest of the structure and the achieved effect remain unchanged.
