The invention relates to a catch basin system, which comprises a catch basin and a hanging basket 4 arranged in the catch basin, wherein the catch basin comprises a well body 1 with a hollow interior and a bottom communicated with a drainage pipeline, and a grate 2 arranged above the well body 1, a first concave table 11 is arranged on the inner side surface of the well body 1, which is close to a road surface, along the running direction of a vehicle, the first concave table 11 is provided with a first surface for receiving the grate 2, the side surfaces of the first concave table are respectively provided with a guide rail 22 parallel to the side surfaces, and one end of the grate 2 is provided with a connecting device which is connected with the guide rails 22 and enables the grate 2 to slide along the guide rails; the connecting device comprises a connecting ring 21 arranged on the periphery of the guide rail 22 and a bolt through hole 25 arranged at one end of the grate 2 and used for allowing two end parts of the connecting ring 21 to pass through, and a fastening device 23 is arranged after the two end parts of the connecting ring 21 pass through the bolt through hole 25.

The guide rail 22 may be preset on the inner side wall of the catch basin, which is close to the road surface, in advance by adopting a pouring mode; the pavement can also be carried out in a later drilling and pouring mode. The guide rail 22 is required to be spaced apart from the inner side wall of the well body 1 so that the connection means can slide on the guide rail 22.

Specifically, the connecting ring 21 hooks the guide rail 22, passes through a bolt through hole 25 at one end of the grate 2, and is fixed by a fastening device 23. Of course, the connection ring 21 can be "U" -shaped and ensures that the connection ring 21 has a certain depth, which facilitates the lifting of the grate 2 high enough that the grate 2 can be slid completely onto the road surface. The fastening device 23 can be a nut, and the two ends of the connecting ring 21 are provided with external threads matched with the nut, so that the detachable connection between the grate 2 and the guide rail 22 can be realized. The design of the connecting device has a great advantage that the conventional grate 2 can be easily remodeled into the grate suitable for the invention, and the end part of the original grate 2 is only required to be punched with the corresponding bolt through holes 25, so that the original grate 2 can be reused, and the material is greatly saved.

When the grate 2 is opened, only one end without the connecting device is lifted to drag to one side, all the weight of the grate 2 is not needed to be born, and the opening size is freely controlled.

Further, the upper surface of the grate 2 at the position where the bolt through holes 25 are provided is provided with a settling tank 24 accommodating the fastening means 23. After the fastening device 23 is fixed in the settling tank 24, when the grate 2 is used normally, the fastening device 23 is flush with the surface of the grate 2, so that the normal running of the passing vehicle is not affected.

Furthermore, the rainwater entering the rainwater well at the initial stage is seriously polluted, but the initial drainage is inconvenient for large-scale industrialization, so that the primary purification is carried out in a basket hanging mode, the water quality is improved, the deep purification is conveniently carried out in a later-stage water treatment plant, and the pressure of the water treatment plant is greatly reduced.

Further, hang basket, including setting up in the catch basin inside and with catch basin matched with first framework 46, one side that first framework 46 is close to the road surface is open-type, the lateral wall and the bottom of first framework 46 are equipped with the through-hole 43 that supplies the rainwater to pass through, the bottom of first framework 46 is equipped with second framework 41, be equipped with water purifier 6 in the second framework 41.

Further, the grate 2 is provided with a rainwater channel, and the distance between the two ends of the rainwater channel is smaller than the distance between the opposite side walls of the hanging basket in the well body. The rainwater can completely enter the hanging basket, so that water flow is prevented from directly entering the drainage pipeline without being treated by the hanging basket 4, and a certain influence is caused on a drainage system.

The water body purifying device 6 can be a charcoal bag made of enteromorpha, on one hand, the enteromorpha is processed to be charcoal, and the charcoal has extremely strong adsorption performance and can adsorb soluble pollutants and fine particles in water; on the other hand, the problem of recycling of the enteromorpha is solved after the enteromorpha outbreak in summer, the main risk source enteromorpha for eutrophication of water bodies in summer coastal areas in China, particularly in northern yellow sea areas is solved, meanwhile, the used biochar bags can be transported to a garbage incineration station for power generation and environment-friendly treatment, and the method has a good ecological synergistic effect and improves the utilization rate of resources.

The number of biochar bags may be one or more, and the second frame 41 may be filled, so that the rainwater can be purified more completely.

Further, a through hole 43 through which rainwater passes is provided at the bottom of the second frame 41. In order to make the rainwater entering the second frame 41 completely and sufficiently pass through the water purifying device 6, the four side walls of the second frame 41 are not provided with through holes, and the rainwater is discharged only from the through holes 43 at the bottom of the second frame 41 after passing through the water purifying device 6.

Further, the side wall of the second frame 41 is provided with a passage 48 for exchanging the water purifying device 6. The passage 48 is an openable door 47, and the door 47 is locked with the second frame 41 by a locking device. When an operator changes the water purifying device 6, the locking device is opened, the door 47 is opened, the used water purifying device 6 is taken out, a new water purifying device 6 is replaced, the door 47 is closed, and the locking device is locked.

Further, the frame 42 is provided outside the first frame 46 and the second frame 41. The frame 42 is composed of a plurality of transverse and longitudinal reinforcing ribs which are coated on the outer periphery of the first frame 46 and the second frame 41. The frame 42 may be welded integrally with the first frame 46 and the second frame 41, or the first frame 46 and the second frame 41 may be directly placed in the frame 42. The frame 42 improves the strength of the first frame 46 and the second frame 41, and can provide support to the first frame 46 and the second frame 41 when the precipitation amount increases and the amount of water entering the catch basin increases.

Further, the upper end of the frame 42 is provided with a Z-shaped hanging lug 44 which is matched with the edge of the rainwater well. Because the inner structure of the catch basin is a plurality of concave structures, in order to enable the bearing area of the hanging lugs 44 of the hanging basket to be larger, the catch basin is attached to the catch basin as much as possible, and the hanging lugs are Z-shaped. On the other hand, the Z-shaped hanging lugs also enable the hanging basket 4 to keep a certain distance from the rainwater well wall, so that drainage is facilitated. Through the hanging lugs 44, the hanging basket 4 can be directly hung on the rain water well edge without other fixing devices, and the rain water well edge hanging device is very convenient.

Further, the inner wall of the first frame 46 is provided with at least one mosquito repellent device, and the mosquito repellent device comprises a fixing device 49 arranged on the inner wall of the first frame 46 and a mosquito repellent assembly 7 arranged in the fixing device 49.

As the catch basin is a warm bed for breeding mosquitoes and flies, the mosquito-repellent assembly 7 can effectively kill eggs, greatly reduce breeding mosquitoes and flies and improve the environmental quality. The fixing device 49 may be a fixing cylinder with a blind end at the bottom end, and the mosquito repelling assembly 7 is arranged in a rod shape and is inserted into the fixing cylinder. In order to increase the exposed area of the mosquito repellent assembly and to improve the stability of the mosquito repellent assembly, the fixing cylinder may be arranged to be shorter, and a through cylinder with both ends open may be arranged above the fixing cylinder in the same vertical direction.

Further, a receiving plate 11 inclined upward toward the inner wall of the catch basin is provided at the edge of the first frame 46. The receiving plate 45 is used for completely entering rainwater leaking downwards through the grate 2 into the hanging basket 4 as much as possible, intercepting dirt and purifying water, and preventing rainwater from directly entering the drainage pipeline without passing through the hanging basket.

The hanging basket 4 is a cubic open hanging basket, and the length, the width and the height of the hanging basket can be adjusted according to the sizes of different catch basins. In use, a new water purification device 6 is placed in the second housing 41.

Further, the size of the through holes 43 increases from bottom to top. That is, the through hole 43 near the bottom of the first frame 46 is smaller than the through hole 43 near the upper portion of the first frame 41, because, when the precipitation amount is small, some foreign matters such as leaves, butts, caps, plastic bags, etc. can be intercepted by the hanging basket 4, the entry of the water discharge pipe through the through hole is avoided, and the rainwater can be made to enter the water purification apparatus 6 of the second frame 41 as much as possible for preliminary purification. And when the precipitation gradually increases, ponding in the hanging basket 4 is more and more, a large amount of rainwater causes extremely large pressure to the hanging basket 4, so when the water level in the hanging basket 4 rises, water is gradually discharged through the large through holes 43, thereby reducing the bearing pressure of the hanging basket 4 and prolonging the service life of the hanging basket 4. Once the hanging basket 4 is damaged, the effect of intercepting dirt is not achieved, and once the damaged frame body enters the drainage pipeline, the drainage system is influenced more.

The through holes close to the upper edge of the hanging basket can be provided with long strip-shaped overflow holes, so that a large amount of precipitation is conveniently discharged outwards, and the bearing of the hanging basket is reduced; on the other hand, operators can directly hold the overflow holes to take and put the hanging basket, other structures are not needed, and the operation is very convenient. When the intensity of the rainfall is not large, the rainwater enters the hanging basket and is filtered by the water purifying device 6 of the second frame 41, so that the soluble pollutants and fine particles in the rainwater can be effectively removed. When the water quantity entering the catch basin exceeds the percolation capacity of the water body purifying device during heavy rain, the water level in the first frame body rises, and the surplus water quantity is discharged from the through holes or the overflow holes. The hanging basket is cleaned manually at regular intervals, and the water purifying device and the mosquito repelling component are replaced.

The rainwater well system further comprises a warning device, wherein the warning device comprises a warning belt 84 and a supporting device which is connected with the warning belt 84 and used for standing the warning belt 84 above the rainwater well. Through the warning area, can play the effect of warning to passing vehicle and pedestrian, prevent to drop into the rainwater well of opening and cause the damage of vehicle and personnel.

The bottom of the sleeve can be provided with a blind end, so that the bottom of the sleeve can receive the connecting rod after the connecting rod is arranged in the sleeve. Of course, the bottom of the sleeve can also be open, so that the connecting rod can be supported by the bearing device after passing through the sleeve. The gap between the sleeve and the connecting rod in the two cases is not too large, otherwise, the connecting rod is unstable, and the connecting rod can be conveniently taken out and inserted. In addition, can also set up the screw thread of mutually supporting in sleeve inside and connecting rod outside for realize threaded connection between connecting rod and the sleeve, make more firm when making the connecting rod tree like this.

One end of the warning belt 84 is provided with a fixing hole 85, and the other end of the warning belt 84 is provided with a fixing sleeve 83 sleeved at the end part of the connecting rod 82. When the warning device is used, the fixing sleeve 83 of the warning belt 84 is sleeved at the end part of the connecting rod 82, the connecting rod 82 is inserted into the connecting rod fixing device, and meanwhile, the fixing holes 85 of the warning belt 84 are hung on the supporting device 8 at the diagonal position, so that the two warning belts 84 are in an X shape after being installed, and a warning effect can be well achieved.

When the strainer 2 is required to be opened to operate the rainwater well, one end of the strainer 2 without the connecting device is lifted and dragged to one side, an operator does not need to bear all the weight of the strainer, and the opening size of the rainwater well can be freely controlled. The rainwater well is overhauled daily, monitoring data are extracted or when no one is looking after the grate is opened for other reasons, two connecting rods are taken out and inserted into the connecting rod fixing device, an overhauling personnel sleeves the fixing sleeve of the reflecting strip on the top of the connecting rod, and the fixing hole at the other end is hung on the supporting device at the diagonal angle of the rainwater well.
