Description
Technical field
The utility model belongs to machinery manufacturing technology field, specifically, relates to a kind of metope cleaning device, more particularly,Relate to a kind of efficient robot for cleaning wall surface.
Background technology
High building, along with the development of urban modernization, becomes more and more general. Along with the increase of floor quantity, for high building wallClean and but become a heavy and dangerous work. Normal employing hoistable platform or hanging basket carrying cleaning personnel have come both at home and abroad at presentThe cleaning of high building wall in pairs. And not only inefficiency of this kind of cleaning method, somewhat expensive, and also safety coefficient is low, Chang YouqingThe generation of clean personnel's falling accident, cleans waste water simultaneously and falls along metope, easily pollute surrounding enviroment, and causes water resourceA large amount of wastes. Therefore be badly in need of utilizing machine to substitute the cleaning of manually carrying out high building wall.
At present for the existing correlative study of high building wall cleaning robot. As documents 1: Granted publication number is CN101513336B, the applying date is on March 28th, 2009, discloses the patent document that name is called a kind of device for cleaning tall building, comprises dressHave the motor vehicle of generator and computer system, motor vehicle is provided with and is connected by two liftables the suspension arm support that moves forward and backwardCleaning device, cleaning device can with arm and between it set arm capstan winch be connected flexible tune of traction of the carrying cable of outputWhole its position, the high-pressure water tank being connected with high-pressure hydraulic pump is also established on motor vehicle top, and high-pressure water tank is provided with by water tank bobbin and regulatesFeed pipe output, that be communicated with cleaning device; Cleaning device comprises the cleaning framework that is provided with hairbrush, hole for water spraying and scraper plate, hairBrush connects driven rotary by motor, and hole for water spraying is established on hairbrush top, and hole for water spraying top is scraper plate. This invention mainly relies on a brush twoThe physics mode that punching three is scraped cleans glass curtain wall, and simple in structure, cleaning process safety labor-saving, has effectively reduced labor strength,Improve operating efficiency, reduced cleaning cost. But this invention is in the course of the work, the contact of itself and metope is fixed,Can not regulate according to specific circumstances and the contact of metope, the waste water of its cleaning simultaneously falls along metope, to ring aroundCertain influence is caused in border.
Documents 2: Granted publication number is CN1265756C, the applying date is on July 29th, 2004, discloses name and has been calledThe patent document of high building glass curtain wall cleaner system, comprises top safety, cleaning machine body, portable supervising device downstairsAnd electrical control gear. Cleaning machine body, under the draw of roof hoist engine, relies on sealing mechanism, utilizes Double-sucker negative pressureAdsorbing mechanism simultaneously or be alternately adsorbed in glass wall, and is coordinated cleaning machine body self gravitation and is moved from top to down, simultaneously at itUnder the cooperation of wiper mechanism, water circulation recovering mechanism, obstacle detection mechanism, cleaning apparatus structure, complete cleaning to glass wall andCross over the functions such as window frame class obstacle; Top safety guarantees that body completes cleaning and obstacle detouring task, and supplies with body power supply, gasSource and water source; Portable supervising device sends action command in wireless monitor mode downstairs, and supervises in real time by wireless video monitorDepending on wall cleaning performance, complete whole cleaning task by the each actuating unit of electrical control gear control. This invention can be real wellNow keep away barrier, and can complete a series of cleaning task, but its utilization rate to water is lower, and cleaning performance is poor.
Documents 3: Granted publication number is CN100594833C, the applying date is on January 8th, 2008, discloses name and has been calledThe patent document of tall building climbing wall water cleaning method and complete set of equipments, includes filtered water tank, the high-pressure pump machine being connected with filtered water tankGroup, climbing robot, the output high-pressure water pipe of high-pressure pump unit is connected on the jet nozzle of climbing robot, true pump machineBetween the true chamber case dish of group and climbing robot, be connected with sewage recovery tube, the output sewage of vavuum pump unit is through sewage water filtrationTreatment facility is discharged to pond, is connected with hoist engine on climbing robot, and is connected with electrical control cubicles by control line. This invention canBy sewage collecting, reduce the impact on surrounding environment. But because it processes the sewage process of collecting, and be delivered to filtered water tank,Make the water quality of sewage after treatment identical with clear water, high to treatment facility requirement, make equipment become complicated, and increased one-tenthThis. Due to its cleaning device design shortcoming relatively, cause cleaning performance poor simultaneously.
In sum, there is following problem in current cleaning robot: the pressure of (1) cleaning robot and metope is uncontrollable, noCan be adjusted according to specific circumstances, make to clean in cleaning process limited, occur cleaning not exclusively, or cleanedComplete but the situation serious to the damage of metope; (2) sewage after cleaning robot cleaning can not be collected effectively, makes dirtWater falls along metope, has had a strong impact on surrounding enviroment; (3) design of wiper mechanism is short of relatively, in cleaning process, lack infiltration,Scrub, the process of secondary cleaning, especially lack the process of secondary cleaning, make cleaning performance poor; (4) part cleaning robotPeople has carried sewage-treatment plant, but because it processes the sewage process of collecting, and be delivered to filtered water tank, make after treatmentThe water quality of sewage is identical with clear water, high to treatment facility requirement, makes equipment become complicated, and has increased cost.
For the problems referred to above, current cleaning robot does not solve, or has only solved subproblem, is therefore badly in need of upperThe problem of stating all solves, to improve cleaning performance, saving water resource, the impact of reduction on surrounding enviroment of cleaning robot.
