Description
Technical Field
The invention relates to the field of cleaning treatment of the surface of an underwater part of a rubber dam, in particular to an underwater cleaning head of the rubber dam and cleaning equipment with the cleaning head.
Background
The rubber dam is used as a low-head water retaining building and is widely used for water storage of town river channels and improving local ecological environment. The rubber dam at present has the following problems in the using process: 1) The part immersed under water for a long time is easy to adhere to sludge and grow bacteria, black spots appear on the surface of the rubber dam due to the growth of the bacteria on the surface of the dam bag, the rubber molecular structure in the rubber dam bag is damaged along with the gradual flaking of the increase of the number of the spots, the rubber layer is aged in advance, and the service life of the rubber dam is shortened; 2) Because silt and bacteria are attached to the dam bag to form an adhesion layer, anaerobic algae can be attached to the surface of the dam belt to grow, the attractiveness of the dam bag is affected, and most importantly, the algae root system is adsorbed on the adhesive layer of the dam bag at the place where the bacteria of the dam bag are in a sheet form, so that the rubber layer is aged and cracked in advance, and the service life of the rubber dam is shortened.
In order to inhibit bacterial reproduction, a solution of coating a bacteriostatic coating on the surface of a dam bag is also presented in the prior art, but because the river channel condition is complex, sundries are often accumulated in front of a rubber dam, the coating can be scratched under the action of water flow, and the bacteriostatic effect is invalid, so that the effect is not ideal, the cost is relatively high, and the method is not practical.
For the above reasons, it is most common practice at present to manually maintain and overhaul the rubber dam at regular intervals, for example, to manually clean the sludge and algae adhered to the surface of the dam bag when the rubber dam is operated for a certain period of time (generally more than 1 year depending on the influence of river water quality and the like).
Since maintenance and overhaul of the rubber dam mainly aims at the underwater part, the dirt removal is concentrated under water, although in the prior art, a cleaning device for underwater cleaning is available, such as a cleaning device for immersing surfaces, disclosed in application number 201980016066.0, and is used for cleaning underwater fish-farming cages, the main body is a rotating brush which is used for removing attachments (such as dirt, shells, parasites and the like) on an underwater net structure, and due to the characteristics of the net structure, the brush can be matched with the brush to well remove attachments on a silk screen.
However, the cleaning device of the rotary brush has poor cleaning effect on the scale attached to the non-net-shaped whole surface, such as the attachment on the surface of the rubber dam, due to the softness of the brush, and is not suitable for cleaning the rubber dam.
In the prior art, no special equipment for cleaning sludge and algae on the surface of the dam bag exists, and a scraper type component is generally adopted, and is driven by manual power or mechanical power, so that scraping is carried out along the surface of the dam bag by scraper-like cleaning equipment, thereby scraping attachments on the surface of the dam bag and completing cleaning of the surface of the dam bag.
However, the conventional scraper cleaning member has the following problems when cleaning: 1) The scraper blade class cleaning element, whether arc or straight plate shape, can all appear because the water flow resistance is big during the operation of scraping under water, lead to the power loss to increase, the cleaning efficiency is low, even appear cleaning the problem that the effect is not ideal; even if holes are formed in the scraping plate, the expected cleaning effect and efficiency are difficult to achieve; 2) Because of the different types of rubber dams, and even the different heights of the same dam, the curvature curves of the surfaces are different, during the scraping operation, only a small surface area can be scraped each time, and the angle of the scraper needs to be changed frequently, resulting in low cleaning efficiency.

the rotating speed of the turntable is generally adjusted according to actual conditions, only the metal wire 3 arranged between the two closed-loop tracks 2 is required to ensure that the middle area of the two closed-loop tracks 2 can deviate from the projection range of the closed-loop tracks 2 by virtue of centrifugal force in the rotating process, and the rotating speed of the turntable can be generally required to be 500r/min, and the rotating speed can be further increased, for example, the rotating speed is adjusted to 800-1200r/min, the specific rotating speed is required to be properly adjusted according to the factors such as the number of rotating centers, the underwater depth (related to water pressure and resistance), the diameter of the metal wire 3 and the like, the two closed-loop tracks 2 respectively encircle the two turntable, each closed-loop track 2 encircles one turntable, the two closed-loop tracks 2 are driven to rotate by the two turntable, a plurality of metal wires 3 are arranged between the two closed-loop tracks 2, and the strength is ensured, the diameter of the metal wire 3 is generally not less than 2mm, but also not more than 5mm, the initial length of the metal wire 3 is not less than the distance between the two closed-loop tracks 2, when only one rotation center 1 exists, the initial length of the metal wire 3 is greater than the distance between the two closed-loop tracks 2, generally determined according to the size of the shell 5, the initial length is generally 1.5-3 times the distance between the two closed-loop tracks 2, when two or more rotation centers 1 exist, the initial length of the metal wire 3 is equal to or greater than the distance between the two closed-loop tracks 2, so that the metal wire 3 contacts with the rubber dam surface to form a scraping and cleaning area 4 in the synchronous rotation process of the metal wire 3 along with the closed-loop tracks 2, when the metal wire 3 collides with the dam surface in the rotation process, the metal wire 3 is always kept in a rotation state, and therefore a certain displacement distance is generated when the metal wire 3 is attached to the dam surface, the surface of the dam bag in the displacement distance is scraped, and the metal wire 3 is a flexible metal wire, so that the shape of the surface of the dam bag can be automatically changed, and the dam bag is suitable for different positions and different radians; the rotating shaft 101 is a hollow rotating shaft with pressurized water flowing inside, the hollow rotating shaft is driven to rotate by a waterproof motor, the pressurized water is introduced into the hollow rotating shaft through an existing rotary joint, the pressurized water is pumped in by a water pump and can be sprayed out of water for a distance, the distance is actually the distance from the rotating shaft 101 to the surface of a dam bag, and the diameter of the rotating disc is generally 10-30cm, so that the water sprayed out of the rotating shaft 101 can be ensured to keep a certain impact force to be sprayed out of the water for a distance of 1m under the water in practice, and the formation of enough turbulent flow on the surface of the dam bag is ensured; in practice, pressurized water is generally introduced from two ends of the rotating shaft 101 and is finally sprayed out from the spray holes of the water spraying area 102, the area between the two rotating discs is divided into a water spraying area 102 close to the two rotating discs and a water returning area 103 in the middle, the length of the water returning area 103 generally accounts for 20-30% of the length of the rotating shaft 101 between the two rotating discs, the spray holes sprayed by the water spraying area 102 are distributed obliquely towards the scraping and cleaning area 4, in practice, the spray holes can be distributed around the rotating shaft 101 and can also be distributed on one side of the water spraying area facing the scraping and cleaning area 4, and the spray holes on the two water spraying areas 102 are all inclined towards the water returning area 103, and the water sprayed out from the spray holes can form turbulent flow under water.
It should be noted that, because of great underwater resistance, the conventional method of flushing the surface of the dam bag of the rubber dam by using high-speed water flow requires great equipment to provide enough water pressure and impact force to meet the flushing requirement; in this embodiment, the pressurized water sprayed from the rotating shaft 101 does not need to have a large pressure to perform flushing, and the main purpose of the pressurized water is to form turbulence at the scraping and cleaning area 4 and cooperate with the scraping action of the metal wire 3, so as to jointly realize the cleaning action, rather than simply using the water flow to impact the dam belt for cleaning.
