Most of the existing water utilization pipelines are not provided with impurity removal parts, so that sand, stone, soil or other impurities flowing along with water flow can cause impact damage or corrosion damage to equipment and parts of hydraulic engineering. At present, filter screens are arranged on some water utilization pipelines in the market and are used for filtering sand, stone, soil or other sundries.

However, in the actual use process, the existing pipeline with the filter screen has the following defects:

firstly, the sand, stone and soil which cannot pass through the filter screen are easily deposited on the front side of the filter screen and cannot be discharged in time, so that the pipeline is blocked;

secondly, as the volume of the sandstone soil is different and the size of the filter grooves of the filter screen is fixed, if the volume of the sandstone soil is too large, the filter grooves of the filter screen are easily covered, so that water flow cannot normally pass through the filter screen to cause pipeline blockage;

thirdly, the sand and stone soil is easy to adhere to the inner wall of the pipeline at the front side of the filter screen, and the pipeline can be corroded after being remained for a long time, so that the service life of the pipeline is shortened.

When the plurality of brush pieces 71 are in the first state, the return spring L is stretched by the sliding disc 73 to be in a stretched state, so that the sliding disc 73 has a tendency of moving downwards, and because the sliding disc 73 is in threaded connection with the driving rod 72 and the driving rod 72 is rotatably mounted on the support pillar 6, the contraction force of the return spring L can act on the driving rod 72, so that the driving rod 72 is difficult to rotate on the premise of not being subjected to external force, the self-locking capability of the driving rod 72 is improved, and the driving rod 72 can be driven to rotate when and only when the second driving part 82 is connected with the driving rod 72;

when the driving rod 72 is driven by the second driving portion 82 to drive the sliding tray 73 to move downwards, the plurality of brush pieces 71 move to a second state along with the downward movement of the sliding tray 73; in the process of brushing the inner tube wall of the filter tube 2 by the plurality of brush pieces 71, the tube wall applies pressure to the plurality of brush pieces 71, so that the sliding disc 73 tends to move up, and since the return spring L is in an initial state at this time, the return spring L needs to overcome the pulling force of the return spring L if the sliding disc 73 is to be moved up, the pulling force of the return spring L can effectively offset the pressure applied to the plurality of brush pieces 71 by the inner tube wall of the filter tube 2, and the stability of the whole pipeline cleaning mechanism 7 is improved.

Referring to fig. 11 to fig. 22, the first driving portion 81 includes a motor 811, a rotating shaft 812 and a driving block 813, one end of the top pillar 6 penetrating into the driving cavity 50 is provided with a movable cavity 61, and a collision-proof opening 61f communicating the movable cavity 61 and the driving cavity 50; the motor 811 is mounted on the housing 5, the first end of the rotating shaft 812 is in driving connection with the motor 811, the second end of the rotating shaft 812 penetrates through the driving cavity 50 and the anti-collision port 61f to the movable cavity 61, the driving block 813 is mounted at the second end of the rotating shaft 812, and the driving block 813 is provided with a driving groove 813 d; the top column 6 is provided with a driven column 61d inside the movable cavity 61, and the driven column 61d is in driving connection with the driving groove 813 d; a guide post 6w coaxially designed with the driven post 61d is arranged on the outer side of the top post 6, a guide groove 50w matched with the guide post 6w is arranged in the driving cavity 50 of the shell 5, and the guide groove 50w is designed in a rectangular ring shape; the starting motor 811 drives the driving slot 813d to rotate so as to drive the top pillar 6 to rotate around the axis of the driving cavity 50, and further drives the guide pillar 6w to move around the guide slot 50w in a circulating manner, so that the top pillar 6 rotates around the axis of the driving cavity 50 first and then moves along the length direction of the driving cavity 50.

For convenience of understanding, in the embodiment of the present invention, the guide groove 50w having a rectangular ring-shaped design is divided into a first section, a second section, a third section and a fourth section, wherein the first section is parallel to the third section, and the second section is parallel to the fourth section; the first sections of the first section, the second section, the third section and the fourth section are sequentially connected to form a closed loop, and each connecting point of each section is designed in a rounded shape so as to facilitate the guide post 6w to pass through;

specifically, the following description is for the entire course of motion:

as shown in fig. 17, in the first step, the top pillar 6 is in the initial position in the conventional case, and the guide pillar 6w is located at the starting point of the first section of the guide groove 50w, i.e. the connection point of the first section and the fourth section; after the motor 811 is started, the motor 811 drives the rotating shaft 812 to rotate, the driving groove 813d drives the driven column 61d to deviate along with the rotation of the rotating shaft 812, and due to the design of the guiding groove 50w, the guiding column 6w moves along the length direction of the first section of the guiding groove 50w, so that the ejection column 6 rotates by a certain angle in the positive direction of the home position;

as shown in fig. 18, in the second step, after the guide post 6w moves to the end of the first section of the guide, i.e. the connection point between the first section and the second section, the motor 811 continues to drive the rotating shaft 812, so that the guide post 6w is transferred to the second section and moves along the length direction of the second section, and further drives the top post 6 to move forward along the length direction of the driving cavity 50, so that the top post 6 approaches the filter block 3;

as shown in fig. 19, in the third step, until the guiding column 6w completely moves to the end of the second section, that is, the connection point between the second section and the third section, the motor 811 continues to drive the rotating shaft 812, so that the guiding column 6w is transferred to the third section and moves along the length direction of the third section, and further the top column 6 is driven to rotate in the opposite direction at the position by a certain angle, and at this time, the range of the rotation angle of the top column 6 is the same as the range of the rotation angle of the lock when the guiding column 6w moves along the first section of the guiding groove 50 w;

as shown in fig. 20, in the fourth step, after the guide post 6w moves to the end of the third section of the guide, i.e. the connection point between the third section and the fourth section, the motor 811 continues to drive the rotating shaft 812, so that the guide post 6w is transferred to the fourth section and moves along the length direction of the fourth section, and further drives the top post 6 to move reversely along the length direction of the driving cavity 50, so that the top post 6 is far away from the filter block 3;

as shown in fig. 18-fig. 20, until the guide post 6w completely moves to the end of the fourth section, i.e. the connection point between the fourth section and the first section, at this time, the top post 6 moves to the initial position, i.e. the position of the first step, and the motor 811 continues to operate to circulate the above four steps, so that in the process of actually driving the top post 6 by the first driving portion 81, the main actions are forward rotation, forward movement, reverse rotation, and reverse movement, and a closed operation loop is formed;

because the plurality of brush pieces 71 are all arranged on the top post 6 and move along with the top post 6, when the top post 6 rotates in the positive direction, the plurality of brush pieces 71 also deviate, and at the moment, the top post 6 moves in the positive direction, so that part of the pipe wall in the filter pipe 2 can be brushed; when the top pillar 6 rotates reversely, the plurality of brush pieces 71 also shift, and the top pillar 6 moves reversely at this time, so that the remaining tube wall inside the filter tube 2 can be brushed, and therefore, the plurality of brush pieces 71 can completely clean the tube wall inside the filter tube 2.

Referring to fig. 11 to fig. 24, the second driving portion 82 includes a first cylinder 821 and an adjusting rod 822, the housing 5 is further provided with an adjusting groove 51 communicating the driving chamber 50 with the outside, the adjusting rod 822 is slidably mounted in the adjusting groove 51, and a first end of the adjusting rod 822 is provided with a locking groove 822k with an opening; a clamping block 72k is arranged at one end of the driving rod 72, which is far away from the top column 6, and corresponds to the clamping groove 822 k; the first cylinder 821 is installed on the housing 5, the telescopic end of the first cylinder 821 is in driving connection with the second end of the adjusting rod 822, and the adjusting rod 822 is driven by the first cylinder 821 to move along the length direction of the adjusting groove 51, so that the clamping groove 822k has a first position separated from the clamping block 72k and a second position clamped with the clamping block 72 k.

Because the sliding disc 73 is installed on the top column 6 and one end of the driving rod 72 is in threaded connection with the sliding disc 73, the sliding disc 73 and the driving rod 72 rotate along with the rotation of the top column 6; when the jack 6 moves, the slide plate 73 and the drive lever 72 move therewith;

because the guide slot 50w is divided into four sections, when the guide column 6w is on the first section of the guide slot 50w, the control motor 811 rotates forward to make the top column 6 rotate forward, if one end of the driving rod 72 is fixed, the sliding disc 73 will move downward along the length direction of the sliding slot 6c along with the rotation of the top column 6, and further drive the first swing rod 74 and the second swing rod 75 to open, so that the plurality of brush pieces 71 move from the first state to the second state;

similarly, when the guide post 6w moves on the first section of the guide slot 50w, the control motor 811 is controlled to rotate reversely so that the prop 6 rotates reversely, if one end of the driving rod 72 is fixed, the sliding tray 73 will move upwards along the length direction of the sliding slot 6c along with the rotation of the prop 6, and further drive the first swing link 74 and the second swing link 75 to contract, so that the plurality of brush pieces 71 move from the second state to the first state;

therefore, in combination with the above structure, the present invention designs the adjusting lever 822, and controls the plurality of brush blades 71 to move to the first state or the second state by the engagement of the locking slot 822k on the adjusting lever 822 and the locking block 72k of the driving lever 72, and the specific operations are as follows:

under the conventional condition, the top column 6 is at the initial position, the plurality of brush pieces 71 are in the first state, the clamping groove 822k on the adjusting rod 822 is at the first position separated from the clamping block 72k on the driving rod 72, at the moment, the clamping groove 822k is separated from the clamping block 72k, the driving rod 72 is not limited, and the movement of the top column 6 can be directly controlled through the motor 811;

when the inner wall of the filter tube 2 needs to be brushed, the top pillar 6 is ensured to be at the initial position, and at this time, the first cylinder 821 is started to drive the adjusting rod 822 to move along the length direction of the adjusting groove 51, so that the clamping groove 822k moves from the first position to the second position and is clamped with the clamping block 72k to fix the driving rod 72; at this time, the motor 811 is started to rotate forward to drive the guide post 6w to move in the forward direction of the first section of the guide slot 50w, so that the sliding plate 73 moves down along the length direction of the sliding slot 6c to drive the plurality of brush pieces 71 to the second state, and the plurality of brush pieces 71 are away from each other and expand;

when the guiding post 6w moves to the connecting point between the first end and the second section of the guiding slot 50w, the first cylinder 821 is activated to drive the adjusting rod 822 to return to the original position, so that the engaging groove 822k moves from the second position to the first position.

Similarly, when the plurality of brush pieces 71 need to be adjusted to the first state, the top pillar 6 is moved back to the initial position, and at this time, the first cylinder 821 is started to drive the adjusting rod 822 to move along the length direction of the adjusting groove 51, so that the clamping groove 822k moves from the first position to the second position and is clamped with the clamping block 72k to fix the driving rod 72; at this time, the starting motor 811 rotates reversely to drive the guiding post 6w to move in the opposite direction of the first section of the guiding slot 50w, so that the sliding plate 73 moves upwards along the length direction of the sliding slot 6c to drive the plurality of brush pieces 71 to the first state, and the plurality of brush pieces 71 contract and approach each other.

In summary, the present invention adjusts the usage status of the plurality of brush pieces 71 by means of the synchronous cooperation between the motor 811 of the first driving portion 81 and the second driving portion 82, so as to reduce the occupied space, and the present invention has a simple structure and can effectively reduce the manufacturing cost.

It should be noted that the second driving portion 82 in the present invention can also be designed as a driving source with independent design, for example, a mechanism such as a motor 811 or a handwheel is directly adopted to directly drive the driving rod 72; on the other hand, in the present invention, the first cylinder 821 can be directly removed, and a dial block is designed at the second end of the adjusting rod 822, so that the user can conveniently and manually adjust the position of the locking groove 822 k.

Referring to fig. 3 to 9, further, in order to prompt a user of a current position of the slot 822k and facilitate the user to manipulate the adjusting lever 822, in the present invention, a reference mark 822b is further disposed on a second end of the adjusting lever 822, a first indicator mark 5b1 and a second indicator mark 5b2 are disposed on the housing 5 corresponding to a first position and a second position of the slot 822k, when the slot 822k is at the first position, the first indicator mark 5b1 is aligned with the reference mark 822b, and when the slot 822k is at the second position, the second indicator mark 5b2 is aligned with the reference mark 822 b.

It should be noted that, in order to facilitate the user to separately control the operation states of the motor 811, the first cylinder 821, the second cylinder, and the water flow regulating valve 21F, the casing 5 of the present invention is further provided with a control box electrically connected to the control motor 811, the first cylinder 821, the second cylinder, and the water flow regulating valve 21F, and the control box is provided with a corresponding control button.

Referring to fig. 23 to 27, in view of the fact that after the driving rod 72 is used for a long time, the fixture block 72k may be worn and cannot be completely fitted with the fixture groove 822k, in order to solve the problem, the present invention further includes an anti-collision mechanism 9, where the anti-collision mechanism 9 includes an anti-collision plate 91 and a first spring 92; fixture block 72k is square in design, fixture slot 822k is also square in design, and the cross-sectional area of fixture slot 822k is larger than that of fixture block 72 k; an accommodating hole 822z is formed in the inner groove wall of the clamping groove 822k, the first spring 92 is installed in the accommodating hole 822z, one end of the first spring 92 is fixedly connected with the anti-collision plate 91, and the other end of the first spring 92 is fixedly connected with the bottom wall of the accommodating hole 822 z; one end of the anti-collision plate 91 close to the opening of the clamping groove 822k is provided with an inclined block 91x which is designed to be inclined outwards; four groove walls are arranged in the clamping groove 822k, the four groove walls are provided with placing holes 822z, four first springs 92 are arranged corresponding to the four placing holes 822z, and four anti-collision plates 91 are arranged corresponding to the four first springs 92; when the four first springs 92 are in the initial state, the cross-sectional area of the enclosed space formed by the mutual enclosure of the four crash-proof plates 91 is smaller than the cross-sectional area of the latch block 72k, and the cross-sectional area of the enclosed opening 91x0 formed by the mutual enclosure of the four oblique blocks 91x is larger than the cross-sectional area of the latch block 72 k.

Specifically, when the top post 6 is at the initial position, in the process that the clamping groove 822k moves from the first position to the second position, the clamping block 72k on the driving rod 72 firstly extends into the enclosed opening 91x0 formed by the four inclined blocks 91x and abuts against the four inclined blocks 91x, the adjusting rod 822 is continuously moved, so that the clamping block 72k extrudes the four inclined blocks 91x to drive the four anti-collision plates 91 to expand, and the first spring 92 is extruded by the anti-collision plates 91 to store energy and compress; until the clamping block 72k is completely clamped into the enclosed space formed by the four crash-proof plates 91, the first spring 92 keeps the current position and drives the four crash-proof plates 91 to extrude the four sides of the clamping block 72 k.

Because the cross-sectional area of the enclosed opening 91x0 formed by the mutual enclosing of the four oblique blocks 91x is larger than that of the fixture block 72k, the fixture block 72k is easily clamped into the enclosed opening 91x 0;

because the cross-sectional area of the enclosed space formed by the mutual enclosure of the four anti-collision plates 91 is smaller than that of the fixture block 72k and the design of the first spring 92, the enclosed space formed by the mutual enclosure of the four anti-collision plates 91 can be changed along with the compression of the first spring 92;

when the fixture block 72k is not worn, the fixture block 72k is completely clamped into an enclosed space formed by the four anti-collision plates 91, the four anti-collision plates 91 respectively abut against the four groove walls of the clamping groove 822k, and at this time, the first spring 92 is at the compression limit;

if the fixture block 72k is worn and the sectional volume of the fixture block 72k is smaller than the sectional area of the clamping groove 822k, the first spring 92 has a tendency to recover after the fixture block 72k is clamped in the enclosed space, so that the collision-proof plate 91 can be automatically driven to be attached to the four sides of the fixture block 72k, the size of the enclosed space can be adjusted, and the adaptability of the clamping groove 822k is improved.

Referring to fig. 3 to 12, in consideration of the fact that in the actual use process, if the hardness of the sand-gravel-mud block is high, when the top pillar 6 extrudes and crushes the mud block, the sand-gravel or mud block simultaneously applies a reaction force to the filter block 3 and the top pillar 6, so that the filter block 3 and the top pillar 6 are both damaged due to rigid collision with the sand-gravel or mud block, in order to avoid the problem, the invention further comprises a buffer mechanism H, wherein the buffer mechanism H comprises a pressing plate H1 and a second spring H2, and one end of the top pillar 6, which is close to the filter block 3, is provided with a buffer cavity 6H with an opening; a convex column H10 is arranged on one side of the pressure plate H1, which is far away from the filter block 3, one end of the convex column H10, which is far away from the pressure plate H1, slidably penetrates into the buffer cavity 6H, and a limit plate H10x is arranged on the penetrating end of the convex column H10; the second spring H2 is installed in the buffer cavity 6H, and second spring H2 one end offsets with the buffer cavity 6H diapire, and the other end of second spring H2 offsets with limiting plate H10 x.

Specifically, under the conventional condition, the second spring H2 is in an initial state, at this time, the pressing plate H1 is far away from one side of the top pillar 6 close to the filter block 3, and the limiting plate H10x abuts against the front side of the buffer cavity 6H, so that the pressing plate H1 is prevented from being separated from the top pillar 6; when the top pillar 6 is driven by the motor 811 to move and extrude the mud block, the pressing plate H1 is firstly abutted against one side of the filter block 3, if the hardness of the mud block is higher, the mud block can apply a reaction force to the pressing plate H1, so that the pressing plate H1 is close to the top pillar 6, and in the process, the second spring H2 is extruded by the limiting plate H10x to compress and store energy, so that the pressing plate H1 is effectively buffered, and the pressing plate H1 is prevented from rigidly colliding with the mud block; when the top column 6 is far away from the filter block 3, the second spring H2 releases energy to recover and drives the pressure plate H1 to return to the original position;

if the hardness of the clod is small, the pressing plate H1 can directly crush the clod without being considered to the top pillar 6, thereby allowing the second spring H2 to maintain the initial state;

in conclusion, the design of the buffer mechanism H can avoid the rigid collision between the top column 6 and the filter block 3 and the mud block with higher hardness, and effectively avoid the damage of the top column 6 and the filter block 3.

It should be noted that, in order to ensure that the pressing plate H1 can be smoothly pressed by the mud block when encountering the mud block with a relatively high hardness, in the embodiment of the present invention, the moving distance of the limiting plate H10x in the buffer chamber 6H should be greater than or equal to the diameter of the sand or mud block which can enter the interior of the filter tube 2 through the water inlet 21, so as to ensure that the pressing plate H1 can be smoothly pressed to close to the top pillar 6 when encountering the sand or mud block with a relatively high volume.

Referring to the attached drawings and fig. 12, a plurality of pressing blocks H11 are arranged on one side of the pressing plate H1 close to the filter block 3, and the pressing block H11 is designed to effectively press and crush mud blocks with larger volume.

It should also be noted that while the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the application, the scope of which is defined in the appended claims and their equivalents.
