[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1-7 As shown, the specific implementation of the present invention is as follows:

[0032] An interception ditch device includes a ditch 1, an interception box 2 for intercepting and purifying water is provided at the bottom of the ditch 1, and the interception box 2 is filled with filler. The ditch 1 is provided with a maintenance mechanism for automatically loosening the filler in the interception box 2 to prevent it from caking, thereby maintaining the flow and cleanliness of the ditch. The maintenance mechanism includes a slidingly installed anti-caking component 4 and a driving component 5 for driving its reciprocating motion.

[0033] The anti-caking component 4 includes two limiting members, each of which includes two limiting shafts 41, and the limiting shafts 41 are located on opposite sides of the interception box 2. A limiting rod 42 is installed between the outer walls of the two limiting shafts 41, and the limiting rod 42 is located above the interception box 2. A sliding sleeve 43 is slidably connected to the outer wall of the limiting rod 42. Several connecting rods 44 are installed between the two sliding sleeves 43, and a loosening rod 45 is installed at the bottom of each connecting rod 44.

[0034] Specifically, air pump assemblies 6 are symmetrically installed on the top of the limiting rod 42 on both sides. The air pump assembly 6 is connected to the sliding sleeve 43 through a telescopic hose 7, and a first one-way valve is provided on the telescopic hose 7. The sliding sleeve 43, the connecting rod 44 and the loosening rod 45 are connected in sequence. The bottom of the loosening rod 45 is connected to a jet nozzle 46, and the bottom of the jet nozzle 46 has several jet holes.

[0035] When the driving member 5 drives the anti-compaction assembly 4 to slide back and forth, the sliding sleeve 43 at both ends is in turn extruded by the air pump assembly 6 at both sides, so that air is generated in the air pump assembly 6 and sprayed into the interception box 2 through the air injection hole of the loosening rod 45.

[0036] From the above description, it can be known that through the ingenious linkage of the sliding sleeve and the air pump assembly, while the loosening rod moves horizontally to physically loosen the soil, air can also be sprayed to the deep part of the adsorption material, which not only further destroys the compaction structure, but more importantly provides sufficient oxygen for the aerobic microorganisms in the filler and the root system of aquatic plants, enhances the biological degradation, and realizes the dual anti-compaction and purification of physical loosening and biological activation.

[0037] Specifically, the cross-sectional shape of the loosening rod 45 is diamond-shaped, and the two sharp corners of the diamond are consistent with the direction of the water flow, and the bottom shape of the air injection head 46 is conical.

[0038] From the above description, it can be known that the diamond-shaped sharp corners can effectively reduce the resistance of the reciprocating motion of the loosening rod in the adsorption material, and reduce energy consumption. The conical air injection head facilitates its insertion into the filler, and at the same time helps to guide the airflow to diffuse in all directions, increases the aeration range, and makes the loosening and reoxygenation effect more uniform and thorough.

[0039] Specifically, the air pump assembly 6 includes a sealed cylinder 61, a sliding rod 62 is slidably connected through the end of the sealed cylinder 61 close to the sliding sleeve 43, the opposite ends of the sliding rod 62 are respectively fixedly connected with an extrusion block 63 and a sealing block 64, and the sealing block 64 is slidably connected with the inner wall of the sealed cylinder 61, the sealing block 64 penetrates and is installed with a second one-way valve, the top of the sealed cylinder 61 is communicated with an air inlet pipe 65 and an air outlet pipe 66, and the air outlet pipe 66 is communicated with the flexible hose 7, the air inlet pipe 65 is provided with a third one-way valve, and the extrusion block 63 is connected with the end of the sliding sleeve 43.

[0040] From the above description, it can be known that the air pump assembly has a compact structure, and ingeniously uses the linear motion of the sliding sleeve as a power source, and through the linkage of the extrusion block, the sliding rod and the sealing block, the mechanical energy is converted into compressed air, without the need for additional air pump, energy saving and reliable. The cooperation of the second one-way valve and the third one-way valve ensures that air can only be sucked from the air inlet pipe and pressed from the air outlet pipe, ensuring the one-way nature of the air path and the continuity of the air injection.

[0041] Specifically, the driving member 5 includes a mounting shell 51 across the top of the trench 1, the inner cavity of the mounting shell 51 is rotatably connected between the opposite ends of the rotating shaft 52, one end of the rotating shaft 52 is connected with the driving motor, the outer wall of the opposite ends of the rotating shaft 52 is provided with an incomplete gear 53, the inner cavity of the mounting shell 51 is slidably connected with a rectangular sliding frame 54 matched with the incomplete gear 53, the upper and lower inner walls of the rectangular sliding frame 54 are symmetrically provided with a rack 55 matched with the incomplete gear 53, and the bottom of the rectangular sliding frame 54 is connected with a fixed rod 56 penetrating through the bottom of the mounting shell 51 and connected with the limiting rod 42.

[0042] From the above description, it can be known that the cooperation of the incomplete gear, the rectangular sliding frame and the rack can convert the continuous rotation of the motor into the automatic reciprocating linear motion of the anti-compaction assembly, the transmission mode runs stably, the reversing is reliable, and by setting the pause gap at both ends of the stroke, a certain buffer time is given to the system (such as the air pump reset), so that the whole device runs more rhythmically and coordinately.

[0043] Specifically, the limiting rod 42 is slidably connected with the limiting shaft 41, the fixed rod 56 is a telescopic rod, the bottom of the mounting shell 51 is provided with a vertical plate 57 matched with the fixed rod 56, one side of the vertical plate 57 close to the fixed rod 56 is provided with a wave groove 58, and the telescopic end of the fixed rod 56 is provided with a connecting piece connected with the wave groove 58, the connecting piece includes a positioning rod 59, and one end of the positioning rod 59 inserted into the wave groove 58 is rotatably connected with a first roller 510.

[0044] From the above description, it can be known that by designing the limiting rod and the limiting shaft to be slidably connected, and designing the fixed rod to be a telescopic rod, and cooperating with the wave groove on the vertical plate, the anti-compaction assembly is given the movement ability in the vertical direction, that is, the movement track of the soil loosening rod is upgraded from pure two-dimensional horizontal sliding to three-dimensional "horizontal-vertical" compound motion. This up-and-down action greatly simulates the effect of manual hoeing, can more effectively pry and break the compaction block, significantly improves the soil loosening effect, and the contact between the first roller and the wave groove is rolling friction, the friction is small, the wear is low, the operation is smooth, which can effectively reduce the risk of mechanism jamming, and ensure the long-term reliable operation of the wave groove transmission mechanism.

[0045] Specifically, the inner cavity of each soil loosening rod 45 is slidably connected with a sealing rod 47, the bottom of the sealing rod 47 is provided with a dredging needle 48 matched with the air injection hole, the top of each sealing rod 47 penetrates out of the connecting rod 44 and is connected through the connecting frame 49, the middle top of the connecting frame 49 is connected with a mounting rod 410, the top of the mounting rod 410 is rotatably connected with a second roller 411 connected with the bottom of the mounting shell 51, and the bottom of the mounting shell 51 is symmetrically provided with a fixed block 511 matched with the second roller 411.

[0046] From the above description: through the cooperation of the fixed block and the second roller, when the anti-caking assembly runs to both ends, the automatic trigger dredging needle moves downward to clean the air injection hole. The process is completely linked by the main driving part, without additional power and control, realizing the periodic and automatic cleaning of the air injection hole, fundamentally ensuring the long-term smoothness of the air path, and greatly improving the maintenance-free nature of the device.

[0047] Specifically, the two fixed blocks 511 are provided with arc transition sections at the ends close to each other.

[0048] From the above description: the contact and separation process of the second roller and the fixed block is more smooth and smooth, avoiding rigid impact and vibration, protecting the dredging mechanism and prolonging its service life, and at the same time, the running noise is lower.

[0049] Specifically, the outer wall of the sealing rod 47 is sleeved with a spring 412, and the spring 412 is located between the connecting frame 49 and the connecting rod 44.

[0050] From the above description: the spring provides a reliable reset force to ensure that the dredging needle can be quickly and completely retracted after the dredging action is completed, and the dredging needle is separated from the air injection hole to avoid affecting the normal air injection function. At the same time, the spring also plays a buffering role, making the dredging action more flexible and preventing the dredging needle from being damaged due to excessive rigidity.

[0051] Specifically, the filler is an adsorbent material with adsorption capacity for nitrogen and phosphorus, and aquatic plants 3 with absorption capacity for nitrogen and phosphorus are planted in the interception box 2, and the soil loosening rod 45 is arranged staggered with the aquatic plants 3.

[0052] From the above description: nitrogen and phosphorus in wastewater can be fully absorbed, and the staggered arrangement of the soil loosening rod and the aquatic plants ensures efficient soil loosening of the whole cross section while perfectly protecting the plant root system, thereby synergistically enhancing the integrity and sustainability of the ecological purification system from the physical and biological aspects.

At the same time, reed, alocasia, and canna indica, which have absorption capacity for nitrogen and phosphorus, are planted in the interception box 2.

[0055] In order to prevent the filling from being hardened automatically, a maintenance mechanism for automatically loosening the filling in the intercepting box 2 to prevent it from being hardened, thereby maintaining the effect of the ditch flow and cleaning, is arranged in the ditch 1, and the maintenance mechanism comprises a slidingly installed anti-hardening assembly 4 and a driving member 5 for driving the reciprocating movement thereof.
