Description

Technical Field

[0001] The present invention relates to the technology of dredging equipment, and particularly to a water supply and drainage dredging equipment. Background Art

[0002] During the process of dredging the water supply and drainage system, it is usually necessary to pump out the silt in the system and squeeze and dehydrate the silt for subsequent transportation and treatment. Most of the existing silt squeezing and dehydrating devices use the method of cooperating a conveyor belt with a pressure roller for squeezing and filtering, that is, directly pumping the silt onto the filter belt of the conveyor, and squeezing the silt through the cooperation of the pressure roller and the conveyor belt to filter out the water in the silt.

[0003] However, in the actual use process, there are some problems with this traditional silt squeezing and dehydrating device. Especially when the treated silt is relatively dense or the amount of silt entering the conveyor belt at one time is large, the silt is prone to accumulate at the pressure roller. This kind of accumulation not only affects the filtering efficiency, but also may cause the excessive squeezing force of the pressure roller on the conveyor belt due to the large amount of silt. Working under the excessive squeezing force for a long time, the conveyor belt is prone to breakage, thus reducing its service life and increasing the maintenance and replacement costs of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a water supply and drainage dredging equipment to solve the problems that when the silt treated by the existing silt squeezing and dehydrating device is relatively dense or the amount of silt entering the conveyor belt at one time is large, the silt is prone to accumulate at the pressure roller, affecting the filtering efficiency, and there is also the problem that due to the large amount of silt, the squeezing force of the pressure roller on the conveyor belt is too large, and working under the excessive squeezing force for a long time causes the conveyor belt to be prone to breakage.

[0015] Furthermore, the A moving driving component includes a moving seat and a telescopic driving member. The moving gear is rotatably installed on the moving seat. The bottom of the moving seat is fixedly connected to the moving end of the telescopic driving member. The fixed end of the telescopic driving member is fixedly connected to the machine frame.

[0016] Further, the auxiliary mechanism includes two groups of auxiliary components symmetrically arranged on both sides of the conveying filter belt. Each auxiliary component includes a plurality of pushing members. The plurality of pushing members correspond to the plurality of carrying rollers one by one.

One end of the pushing plate is connected with a reciprocating driving member for driving the pushing plate to reciprocate along the length direction of the pushing plate.

[0018] Further, the reciprocating driving member includes a transverse groove plate. One side of the transverse groove plate is fixedly connected to the pushing plate.

[0022] Compared with the prior art, for a water supply and drainage dredging device provided by the present invention, through the provided overload prevention mechanism, when the amount of silt is too large and the extrusion force of the extrusion roller on the conveyor belt is too large, the overload prevention mechanism can drive the extrusion roller to move upward in a direction perpendicular to the upper surface of the conveyor belt, thereby reducing or eliminating the excessive extrusion force, effectively protecting the conveyor belt from damage and extending its service life.

[0023] Through the auxiliary mechanism, multiple carrying rollers can be driven to move up and down in a direction perpendicular to the upper surface of the conveyor belt, causing the conveyor belt to vibrate with a certain amplitude. This vibration helps to flatten the silt on the conveyor belt, improve the filtration efficiency of the water in the silt, and prevent the silt from agglomerating and causing extrusion deformation of the conveyor belt;

[0024] Through the triggering mechanism, the deformation of the conveyor belt can be monitored in real time. Once the deformation reaches the preset position, the anti-overload mechanism and the auxiliary mechanism are immediately triggered to work, realizing the rapid response of the mechanism and effectively coping with emergencies such as silt accumulation;

[0025] By setting an adjustable triggering mechanism, the limit position of the trigger plate moving downward can be set according to the actual working needs, so as to flexibly adjust the reaction sensitivity of the device and adapt to the dredging requirements under different working conditions;

[0026] Through the design of the rotary drive mechanism combining gear transmission and link mechanism, it is ensured that the extrusion roller is always driven during the movement process, improving the stability and reliability of the device. Brief Description of the Drawings

Detailed implementation manners

[0040] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , a water supply and drainage dredging device, including a frame 100, two conveying rollers 200 are rotatably installed on the frame 100, and the same conveying filter belt 300 is sleeved outside the two conveying rollers 200. One side of one of the conveying rollers 200 is connected with an A rotation driving member 400 for driving it to rotate around its own axis. The A rotation driving member 400 is a motor or a rotary cylinder, and the output shaft end of the A rotation driving member 400 is fixedly connected with the end of one of the conveying rollers 200. Defining one end of the conveying filter belt 300 as the conveying front end and the other end of the conveying filter belt 300 as the conveying rear end, further including:

[0042] An extrusion roller 510 is disposed at the top of the conveying filter belt 300 and is used to cooperate with the conveying filter belt 300 to extrude the sludge.

[0043] A positioning roller 520 is installed at the bottom of the extrusion roller 510 and is disposed inside the conveying filter belt 300.

[0044] A rotary drive mechanism 600 is connected to one side of the extrusion roller 510, and the rotary drive mechanism 600 is used to drive the extrusion roller 510 to rotate about its own axis.

[0045] A plurality of carrier rollers 700 are disposed inside the conveying filter belt 300, and the plurality of carrier rollers 700 are used to support the conveying filter belt 300.

[0046] An anti-overload mechanism 800 is installed at both ends of the extrusion roller 510, and the anti-overload mechanism 800 is used to drive the extrusion roller 510 to move in a direction perpendicular to the upper surface of the conveying filter belt 300.

[0047] An auxiliary mechanism 900 is used to drive the plurality of carrier rollers 700 to move up and down in a direction perpendicular to the upper surface of the conveying filter belt 300.

[0048] A triggering mechanism 110 is disposed at the bottom of the extrusion roller 510. The triggering mechanism 110 includes a triggering plate 111. The triggering plate 111 is disposed between a carrier roller 700 and the positioning roller 520 on the side close to the positioning roller 520. The triggering plate 111 can move to a preset position in a direction perpendicular to the upper surface of the conveying filter belt 300. After the triggering plate 111 moves to the preset position, the anti-overload mechanism 800 drives the extrusion roller 510 to move upward in a direction perpendicular to the upper surface of the conveying filter belt 300, and the auxiliary mechanism 900 drives the plurality of carrier rollers 700 to move up and down.

[0049] When dredging the water supply and drainage system, it is necessary to pump out the sludge in the water supply and drainage system and then extrude and dehydrate the sludge for easy transportation, etc. In the existing sludge extrusion and dehydration devices, when dewatering the sludge, most of them use the method of extrusion and filtration during transportation. The sludge is directly pumped out onto the conveyor belt of the conveyor. The conveyor belt is of the filter belt type, and a pressure roller is used to cooperate with the conveyor belt to extrude the sludge to facilitate filtering out the water in the sludge. However, in the actual use process, there are situations where some sludge is relatively dense. Once the amount of sludge entering the conveyor belt is large, it will cause some sludge to accumulate at the pressure roller, and it is easy to cause the extrusion force of the pressure roller on the conveyor belt to be too large due to the excessive amount of sludge. In the case of long-term use, the conveyor belt is prone to being damaged due to the large extrusion force, resulting in a reduction in the service life of the conveyor belt and an increase in equipment costs.

[0050] To this end, in the present application, an anti-overload mechanism 800 is provided. When the amount of sludge entering the conveying filter belt 300 at one time is large, the sludge accumulates on the side of the extrusion roller 510 at the front end of the conveying filter belt 300. The extrusion roller 510 extrudes the sludge, and the sludge presses down the conveying filter belt 300. The conveying filter belt 300 presses down the trigger plate 111, and the trigger plate 111 moves downward. The limit position of the downward movement of the trigger plate 111 can be preset in advance, that is, the limit position where the conveying filter belt 300 is extruded and deformed. After the trigger plate 111 moves downward to the preset limit position (preset position), the anti-overload mechanism 800 drives the extrusion roller 510 to move upward in a direction perpendicular to the upper surface of the conveying filter belt 300 to reduce or eliminate the excessive extrusion force brought to the conveying filter belt 300 by the extrusion of the extrusion roller 510 on the sludge; and, the auxiliary mechanism 900 drives a plurality of carrier rollers 700 to move up and down in a direction perpendicular to the upper surface of the conveying filter belt 300. The plurality of carrier rollers 700 move up and down in a small amplitude, and will continuously push and squeeze the conveying filter belt 300, causing the conveying filter belt 300 to vibrate with a certain amplitude. When the conveying filter belt 300 vibrates, the sludge conveyed on the conveying filter belt 300 will be vibrated and spread out, and the filtration efficiency of the water in the sludge will be accelerated, so as to avoid the situation that the excessive volume of the sludge causes too large a deformation amplitude of the conveying filter belt 300, resulting in damage to the conveying filter belt 300 and a reduction in its service life. After the trigger plate 111 is not in the preset position, the anti-overload mechanism 800 drives the extrusion roller 510 to move to the initial position and continue to extrude and filter the sludge.

[0051] Please refer to Figure 2 、 Figure 3 and Figure 5 , in an embodiment of the present invention, the rotary drive mechanism 600 includes two sets of rotary drive components symmetrically arranged at both ends of the extrusion roller 510. The rotary drive component includes a gear A 601, a gear B 602, a gear C 603, a gear D 604, a rotary drive member B 605, a link A 606, a link B 607 and a transmission shaft 608. The gear A 601 is fixedly sleeved on the outside of one end of the extrusion roller 510. One side of the gear A 601 meshes with the gear B 602. One side of the gear B 602 meshes with the gear C 603. One side of the gear C 603 meshes with the gear D 604. The gear D 604 is fixedly sleeved on the output shaft end of the rotary drive member B 605. One end of the link A 606 is rotatably connected to the extrusion roller 510. The gear B 602 is rotatably installed on the link A 606. The transmission shaft 608 is rotatably installed at the other end of the link A 606. The gear C 603 is fixedly sleeved on the outside of the transmission shaft 608. One end of the link B 607 is rotatably connected to the transmission shaft 608. The other end of the link B 607 is rotatably connected to the output shaft of the rotary drive member B 605;

[0052] Specifically, the B rotation driving member 605 is a rotary cylinder or a motor. The B rotation driving member 605 is fixedly installed on the frame 100. The B rotation driving member 605 drives the D gear 604 to rotate. The D gear 604 drives the C gear 603 to rotate. The C gear 603 drives the B gear 602 to rotate. The B gear 602 drives the A gear 601 to rotate. The A gear 601 drives the extrusion roller 510 to rotate. The extrusion roller 510 cooperates with the conveying filter belt 300 to extrude and filter the sludge. When the anti-overload mechanism 800 drives the extrusion roller 510 to move in a direction perpendicular to the upper surface of the conveying filter belt 300, the extrusion roller 510 drives the A gear 601 and the A connecting rod 606 to move. Due to the arrangement of the A connecting rod 606 and the B connecting rod 607, the distances between the A gear 601 and the B gear 602, between the B gear 602 and the C gear 603, and between the C gear 603 and the D gear 604 always remain the same, that is, the meshing state remains unchanged. Furthermore, during the movement of the extrusion roller 510, the driving of the extrusion roller 510 can be always maintained.

[0053] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 7 In an embodiment of the present invention, the anti-overload mechanism 800 includes two sets of anti-overload components symmetrically arranged at both ends of the extrusion roller 510. The anti-overload component includes a support frame 801, a moving rack 802, a moving gear 803, a fixed rack 804, and a moving driving component. The top end of the support frame 801 is rotatably connected to the end of the extrusion roller 510. One side of the support frame 801 is fixedly connected to the moving rack 802. One side of the moving rack 802 meshes with the moving gear 803. The side of the moving gear 803 away from the moving rack 802 meshes with the fixed rack 804. The fixed rack 804 is fixedly installed on the frame 100 through a bracket. One side of the moving gear 803 is connected to an A moving driving component for driving the moving gear 803 to move in the height direction of the support frame 801.

[0054] Specifically, when it is necessary to drive the extrusion roller 510 to move, the A moving driving component is used to drive the moving gear 803 to move in the height direction of the support frame 801 (i.e., move in a direction perpendicular to the upper surface of the conveying filter belt 300). When the moving gear 803 moves, since the fixed rack 804 is fixed to the frame 100, the moving gear 803 rotates while moving. The moving gear 803 drives the moving rack 802 to move. The moving rack 802 drives the support frame 801 to move. And the moving distance of the moving rack 802 is multiple times the moving distance of the A moving driving component driving the moving gear 803. The moving speed of the support frame 801 is multiple times the moving speed of the moving gear 803. That is, the rapid movement of the extrusion roller 510 can be effectively realized. When there is sludge accumulation, the extrusion roller 510 can move quickly to achieve the rapid response of the mechanism.

[0055] Please refer to Figure 7 , in an embodiment of the present invention, the A moving drive assembly includes a moving seat 805 and a telescopic drive member 806. The moving gear 803 is rotatably mounted on the moving seat 805. The bottom of the moving seat 805 is fixedly connected to the moving end of the telescopic drive member 806, and the fixed end of the telescopic drive member 806 is fixedly connected to the frame 100;

[0056] Specifically, the telescopic drive member 806 is a telescopic cylinder or a hydraulic cylinder. When the moving end of the telescopic drive member 806 expands and contracts, it drives the moving seat 805 to move. The moving seat 805 drives the moving gear 803 to move, thereby realizing the movement of the moving gear 803 along the height direction of the support frame 801.

[0057] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 9 , in an embodiment of the present invention, the auxiliary mechanism 900 includes two groups of auxiliary components symmetrically arranged on both sides of the conveying filter belt 300. The auxiliary components include a plurality of pushing members 901. The plurality of pushing members 901 correspond to the plurality of carrying rollers 700 one by one. The tops of the plurality of pushing members 901 are respectively rotatably connected to the ends of the corresponding carrying rollers 700. The outer side walls of the plurality of pushing members 901 are respectively rotatably connected to the frame 100. A spring 902 is sleeved outside each of the plurality of pushing members 901. The tops of the plurality of A springs 902 are respectively fixedly connected to the frame 100, and the bottoms of the plurality of A springs 902 are respectively fixedly connected to the corresponding pushing members 901. A pushing drive member is provided at the bottom of the plurality of pushing members 901. The pushing drive member is used to push the plurality of pushing members 901 to move upward along the height direction of the pushing members 901;

[0058] Specifically, by pushing the plurality of pushing members 901 to move upward along the height direction of the pushing members 901 by the pushing drive member, the A spring 902 is compressed. When the pushing member 901 moves upward, it will drive the carrying roller 700 to move upward. When the pushing drive member does not drive the pushing member 901 to move upward, under the action of the A spring 902, the pushing member 901 moves downward, thereby causing the carrying roller 700 to move downward. In this way, the plurality of carrying rollers 700 can move up and down in a small amplitude. While the carrying roller 700 moves up and down, it can bring a certain jitter to the conveying filter belt 300. When the conveying filter belt 300 jitters, the sludge located on it is leveled, so as to avoid the directly agglomerated sludge being directly squeezed by the squeezing roller 510, thereby effectively avoiding the situation that the squeezing force of the squeezing roller 510 on the conveying filter belt 300 is too large when squeezing the sludge, resulting in the damage of the conveying filter belt 300;

[0059] Please refer to Figure 10, in an embodiment of the present invention, the pushing driving member includes a pushing plate 903, on which a plurality of protrusions 904 are provided. The plurality of protrusions 904 are arranged at equal intervals along the length direction of the pushing plate 903. The pushing plate 903 is slidably mounted on the frame 100, and one end of the pushing plate 903 is connected with a reciprocating driving member for driving the pushing plate 903 to reciprocate along the length direction of the pushing plate 903;

[0060] Specifically, when the reciprocating driving member drives the pushing plate 903 to reciprocate, the protrusions 904 on the pushing plate 903 push the pushing member 901, so as to realize a small movement of the pushing member 901, and then realize a small movement of the carrying roller 700.

[0061] Please refer to Figure 9 , in an embodiment of the present invention, in order to reduce the wear of the pushing member 901, rollers 909 are rotatably mounted at the bottom ends of the plurality of pushing members 901, and one side of the rollers 909 is in contact with the pushing plate 903.

[0062] Please refer to Figure 4 、 Figure 7 and Figure 10 , in an embodiment of the present invention, the reciprocating driving member includes a transverse groove plate 908. One side of the transverse groove plate 908 is fixedly connected with the pushing plate 903. A transverse sliding groove is provided on the transverse groove plate 908, and a push rod 905 is slidably connected to the inner wall of the transverse sliding groove. The bottom end of the push rod 905 is fixedly connected with a turntable 906, and one side of the turntable 906 is connected with a C rotary driving member 907 for driving the turntable 906 to rotate around its own axis;

[0063] Specifically, the C rotary driving member 907 is a rotary cylinder or a motor. The turntable 906 is fixedly mounted on the output shaft of the C rotary driving member 907, and the C rotary driving member 907 is fixedly mounted on the frame 100. The C rotary driving member 907 drives the turntable 906 to rotate. When the turntable 906 rotates, it drives the push rod 905 to rotate. The push rod 905 pushes the inner wall of the transverse sliding groove on the transverse groove plate 908 to drive the transverse groove plate 908 to move. The transverse groove plate 908 drives the pushing plate 903 to move. When the turntable 906 rotates one circle, the pushing plate 903 reciprocates once, so as to realize the rapid reciprocating movement of the pushing plate 903, and then realize the rapid up and down movement of the pushing member 901.

[0064] Please refer to Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 and Figure 9, in an embodiment of the present invention, the triggering mechanism 110 further includes two guide rods 116. The outer sidewalls of the two guide rods 116 are both slidably connected to the frame 100. B springs 112 are sleeved outside the two guide rods 116. The top ends of the two B springs 112 are respectively fixedly connected to the frame 100, and the bottom ends of the two B springs 112 are respectively fixedly connected to the guide rods 116 on one side thereof. A pressure sensor 113 is provided at the bottom end of one of the guide rods 116. A sliding seat 114 is fixedly connected to the bottom of the pressure sensor 113. A B moving driving assembly for driving the sliding seat 114 to move along the length direction of the guide rod 116 is connected to one side of the sliding seat 114;

[0065] Specifically, when it is necessary to specifically set the limit position (preset position) of the trigger plate 111 moving downward, the sliding seat 114 is driven by the B moving driving assembly to move along the length direction of the guide rod 116. When the sliding seat 114 moves, it drives the pressure sensor 113 to move, so as to be able to adjust the limit distance of the guide rod 116 moving downward. After the conveying filter belt 300 is squeezed and deformed by the silt, it will press down the trigger plate 111. The trigger plate 111 drives the guide rod 116 to move downward, and the B spring 112 is stretched. When the guide rod 116 moves downward to contact the pressure sensor 113, the pressure sensor 113 sends a control signal to the controller, and the controller controls the anti-overload mechanism 800 and the auxiliary mechanism 900 to start. For the upward movement distance of the squeezing roller 510 and the duration of the up and down movement of the carrying roller 700, specific settings can be made.

[0066] Please refer to Figure 4 , Figure 6 , Figure 8 and Figure 9 , in an embodiment of the present invention, the B moving driving assembly is a screw rod 115. The upper and lower ends of the screw rod 115 are both rotatably connected to the frame 100. The outer sidewall of the screw rod 115 is threadedly connected to the sliding seat 114, and one side of the sliding seat 114 is slidably connected to the frame 100;

[0067] Specifically, by rotating the screw rod 115, since the sliding seat 114 is slidably connected to the frame 100, when the screw rod 115 rotates, it drives the sliding seat 114 to move, so as to effectively realize the adjustment of the position of the pressure sensor 113.

[0068] In an embodiment of the present invention, a corresponding control unit can be provided for cooperative use. Any one of the controllers can be selected as the control unit and connected to the electrical components in this application to control the opening and closing operations of each electrical component. This part is the prior art. Here, a single-chip microcomputer can be provided as the control unit for demonstration. The single-chip microcomputer in this embodiment is a typical embedded microcontroller (Microcontroller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but it has a small storage capacity, simple input and output interfaces, and low functional consumption.

[0069] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
