[0043] See also Figure 1-8 The present invention provides a technical solution for a purification treatment device applied to a municipal sewage pipe network. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process. The specific operations are as follows.

[0044] A purification treatment device applied to a municipal sewage pipe network is characterized by comprising: a base 1, a support grate 21, a cleaning belt 3, two chains 4, a transmission rod 5, two sprocket wheels 6, a power device 7 and a water bucket 8.

[0045] The base 1 includes a first support block 111 , a second support block 121 and a third support block 131 .

[0046] The first support block 111, the second support block 121 and the third support block 131 form a semi-enclosed structure, so that the whole device can be installed on the side of the road and surrounded by the roadside stone to form a gap. At the same time, the position should be in a low-lying area of ​​the road surface or at the end of the slope to ensure that water flows naturally to the drainage area, that is, to ensure the drainage channel, while not occupying the normal road, to avoid vehicles or other heavy objects from crushing the device.

[0047] The first support block 111 is arranged in the vertical direction, and the first support block 111 is a hollow shell structure. The side wall of the first support block 111 is provided with a first mounting groove 112, and the bottom of the first support is provided with a drain hole 113; the second support block 121 is mirror-distributed with the first support block 111, and the side wall of the second support block 121 is provided with a second mounting groove 122; the first support block 111 and the second support block 121 adopt a split structure, and the split position is located at the horizontal midline of the first mounting groove 112 and the second mounting groove 122, the third support block 131 is horizontally arranged on one side of the first support block 111 and the second support block 121, forming an incompletely closed structure, the third support block 131 is a hollow shell structure, and the third support block 131 1 is provided with an overflow channel 132 at the top of the side wall pointing to the first support block 111. The height of the overflow channel 132 is higher than the top surface of the support grate 21. One end of the overflow channel 132 is lower and the other end is higher. When the water level rises, the water can be discharged through all the overflow channels 132. When the water level drops, the water can still slowly enter the overflow channel 132. When the waterway is blocked, the water level rises and the water will enter from the overflow channel 132. The support grate 21 can be detachably installed in the semi-enclosed structure of the base 1; the two ends of the support grate 21 are respectively located in the first installation groove 112 and the second installation groove 122. The support grate 21 is a grid-like structure, and the grid is larger than the grid of the current grate. The first support block 111 and the second support block 1 The split structure of 21 realizes the detachable effect between the supporting grate 21 and the base 1, and the cleaning belt 3 is sleeved on the outer wall of the supporting grate 21; the cleaning belt 3 has a water-permeable structure, such as a grid-like or perforated design, which can allow water to pass smoothly and prevent debris from blocking the drainage path. The cleaning belt 3 has sufficient flexibility and can maintain smooth operation when running around the outer wall of the supporting grate 21. At the same time, the cleaning belt 3 can be made of wear-resistant rubber, polyurethane or wear-resistant composite materials, etc., which are corrosion-resistant and weather-resistant, and can be used for a long time in a humid, hot and cold alternating and corrosive environment. The two chains 4 are respectively arranged on both sides of the cleaning belt 3. By applying power to the two chains 4, the cleaning belt 3 is driven to run on the supporting grate 21, and the two chains 4 Synchronous movement can ensure the stable operation of the cleaning belt 3. At the same time, the two chains 4 have sufficient strength and tensile resistance. The force is applied to the two chains 4 to reduce the force on the cleaning belt 3. The transmission rod 5 is arranged on the bottom surface of the supporting grate 21, and one end of the transmission rod 5 extends to the inner cavity of the third support seat 131; the transmission rod 5 is used for power transmission, and the two sprockets 6 are arranged on the outer wall of the transmission rod 5 and are respectively engaged with the two chains 4; the two sprockets 6 rotate with the power rod, and the meshing relationship between the sprockets 6 and the two chains 4 is utilized to drive the two chains 4 to operate synchronously. The power device 7 is arranged in the inner cavity of the base 1 and is connected to the transmission rod 5. The water bucket 8 is arranged in the inner cavity of the third support block 131 and is located below the horizontal plane of the overflow channel 132.

[0048] The power device 7 includes: a plurality of guide columns 71 , a water tank 721 , a first spring 73 , a power frame 74 , a gear 751 , a transmission belt 76 and a driving assembly 77 .

[0049] A plurality of guide posts 71 are arranged in the inner cavity of the base 1 in a direction perpendicular to the ground. The water tank 721 is slidably arranged on the plurality of guide posts 71. The water tank 721 is connected to at least two guide posts 71 to ensure that the water tank 721 slides in a direction perpendicular to the ground. The first spring 73 is arranged on the outer wall of the plurality of guide posts 71 and is located at the bottom of the water tank 721. When the water tank 721 is full of liquid, the gravity of the liquid in the water tank 721 is greater than the elastic force of the first spring 73, and the water tank 721 will move downward. When the water in the water tank 721 is discharged, the elastic force of the first spring 73 is greater than the gravity of the water tank 721 itself. Under the action of the first spring 73, the water tank 721 will move up to the initial position. The power frame 74 is arranged on one side of the water tank 721, and the gear 751 is rotatably arranged in the power frame 74 through the shaft 752. The two ends of the shaft 752 are respectively rotatably arranged in the inner cavity of the third support block 131, and the shaft 752 rotates synchronously with the gear 751. The transmission belt 76 is connected between the transmission rod 5 and the shaft 752 to transmit the transmission rod 5 and the shaft 752. The transmission belt 76 can be a flat belt, a synchronous belt, etc. At the same time, the transmission rod 5 and the shaft 752 are respectively provided with matching pulleys to ensure the transmission effect between the transmission rod 5 and the shaft 752. At least one driving component 77 is arranged on the inner wall of the power frame 74, and each driving component 77 is meshed with the gear 751.

[0050] The driving assembly 77 includes: a fixing seat 771 , at least two inserting rods 772 , at least two second springs 773 and a tooth plate 774 .

[0051] The fixed seat 771 is arranged on the inner wall of the power frame 74 along the vertical direction; at least two plug rods 772 are inserted into the outer wall of the fixed seat 771; at least two plug rods 772 both point to the direction of the gear 751, and at least two second springs 773 are respectively sleeved on the plug rods 772, and are arranged between at least two plug rods 772 and the fixed seat 771, and are symmetrically arranged on both sides of the shaft 752; the tooth plate 774 is arranged at the far end of at least two plug rods 772 from the fixed seat 771, and the tooth plate 774 is meshed with the gear 751. The elastic force of the second spring 773 is used to make the tooth plate 774 always abut against the gear 751 to ensure the meshing of the tooth plate 774 and the gear 751.

[0052] Gear 751 and tooth plate 774 are meshed with ratchet teeth, and the ratchet teeth on tooth plate 774 and gear 751 are used to realize one-way transmission of the rack, so that when tooth plate 774 moves to one side, gear 751 can be driven to rotate, and when tooth plate 774 moves to the other side, gear 751 remains stationary. The direction in which the gear can be driven to rotate during the movement of tooth plate 774 is the positive direction, and vice versa.

[0053] There are at most two drive components 77, and when there are two drive components 77, the two drive components 77 are distributed on both sides of the gear 751 in a centrally symmetrical manner. By using two centrally symmetrically distributed drive components 77, when the drive frame reciprocates in the forward and reverse directions, the drive gear 751 rotates in the same direction, so that the cleaning belt 3 always runs in one direction.

[0054] The power frame 74 is slidably disposed on the guide column 71 at the far end away from the water tank 721 , ensuring that the power frame 74 moves synchronously with the water tank 721 in a direction perpendicular to the ground, thereby ensuring the meshing relationship between the gear 751 and the toothed plate 774 .

[0055] A one-way bearing 9 is provided between the transmission rod 5 and the base 1 , so that the transmission rod 5 can only rotate in one direction, thereby preventing the friction force when the tooth plate 774 moves in the reverse direction from causing the gear 751 to rotate in the reverse direction.

[0056] The top of the water tank 721 is provided with a water inlet pipe, and the bottom of the water tank 721 is provided with a magnetic valve 722. The water inlet pipe is connected to the water bucket 8. The liquid enters the water tank 721 through the overflow channel 132 and is collected by the water bucket 8. At least one magnetic valve 722 is provided on the bottom of the water tank 721. Multiple magnetic valves 722 can be provided to ensure the drainage efficiency of the water tank 721. A magnet 723 is provided at a corresponding position on the bottom of the inner cavity of the third support block 131. When the magnetic valve 722 contacts the magnet 723, the magnetic valve 722 is in an open state. At the same time, a corresponding magnetic valve 723 is provided on the bottom of the third support block 131. Drain outlet, when the magnetic valve 722 is separated from the magnet 723, the magnetic valve 722 is in a closed state. When the water tank 721 is full of water, the water tank 721 moves down to the maximum limit, the magnetic valve 722 contacts the magnet 723, the magnetic valve 722 opens, and the water tank 721 drains water. When the drainage is completed, the elastic force of the first spring 73 is used to move the water tank 721 up to the initial position, and the gear 751 is driven to rotate at the same time, wherein the drainage capacity of the water tank 721 is greater than the water intake capacity, to avoid the water intake rate being greater than the drainage rate, resulting in the water tank 721 being unable to move up under the action of the first spring 73.

[0057] Auxiliary wheels 22 are respectively provided at the four corners of the supporting grate 21 . The four auxiliary wheels 22 are respectively engaged with the two chains 4 . The auxiliary wheels 22 are used to support and fix the positions of the two chains 4 , and at the same time ensure the movement path of the cleaning belt 3 .

[0058] When the tooth plate 774 moves in the opposite direction, the tooth plate 774 can move radially for a certain distance, which is enough to disengage the tooth plate 774 from the gear 751. The movement of the tooth plate 774 cannot drive the rotation of the gear 751. The tooth plate 774 can move along the axial direction of the plug rod 772, and the elastic force of the second spring 773 and the ratchet teeth are used to realize the one-way transmission of the tooth plate 774 and the gear 751.

[0059] In the inner cavity of the first support block 111, and above the first mounting groove 112, a baffle 114 is hinged, and a spring leaf 115 is provided between the baffle 114 and the inner wall of the first support block 111, so that the bottom end of the baffle 114 abuts against the surface of the cleaning belt 3 without being subjected to external force. When the cleaning belt 3 is in operation, the cleaning belt 3 will lift up the baffle 114 to pass the debris, so that the debris falls into the inner cavity of the first support block 111. When the cleaning belt 3 is not in operation, the baffle 114 is in a state of abutting against the cleaning belt 3, so that most of the water flow is maintained to flow into the ground through the cleaning belt 3 and the support grate 21. When too much debris is accumulated on the cleaning belt 3, the water level may rise and enter the inner cavity of the third support block 131 through the overflow channel 132 on the third support block 131.

[0060] Working principle:

[0061] During normal drainage, rainwater or sewage flows into the drainage well or pipe below through the cleaning belt 3 and the supporting grate 21. As the debris in the water gradually accumulates on the surface of the cleaning belt 3, the water flow through the cleaning belt 3 and the supporting grate 21 gradually decreases, and the water level on the cleaning belt 3 gradually rises. When the water level rises to the overflow channel 132, the water enters the water bucket 8 and enters the water tank 721 through the water inlet pipe. As the water level in the water tank 721 rises, the overall gravity of the water tank 721 is greater than the elastic force of the first spring 73, and the water tank 721 moves downward. At the same time, the power frame 74 moves downward synchronously. At this time, the tooth plate 774 on one side of the gear 751 is meshed with the gear 751, driving the gear 751 to rotate. At the same time, although the tooth plate 774 on the other side of the gear 751 abuts against the gear 751 under the action of the second spring 773, it does not drive the gear 751 to rotate under the action of the ratchet teeth. The gear 751 rotates, and through the transmission With the cooperation of belt 76, transmission rod 5 will drive cleaning belt 3 to operate on supporting grate 21, and the garbage on cleaning belt 3 will move with cleaning belt 3 toward first supporting block 111 and finally fall into first supporting block 111, and at the same time, water tank 721 moves down to the maximum limit, magnetic valve 722 contacts magnet 723, and the water in water tank 721 is discharged. Under the action of first spring 73, water tank 721 moves up, and in the process that power frame 74 moves up with water tank 721, tooth plate 774 on the other side of power frame 74 drives gear 751 to rotate, so that cleaning belt 3 continues to operate. With the operation of cleaning belt 3, the water path of cleaning belt 3 and supporting grate 21 is opened, and the water level on cleaning belt 3 drops to ensure the smooth flow of water. At the same time, in the normal drainage process, the bottom end of overflow channel 132 still keeps water inflow, but the water inflow is small, so that water tank 721 moves relatively slowly, and cleaning belt 3 also keeps operating.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
