Abstract
The utility model relates to the transformer station auxiliary equipment and specifically relates to a density relay protection cover having a cleaning device. A breaker density relay operates for long term as external equipment, dusts are liable to enter the density relay protection cover, and data reading of the density relay is influenced. According to the density relay protection cover, the cover opens downwards and is a quadrangle casing, a front side board of the cover is provided with an observation port and is equipped with a transparent panel, a horizontal rod of a crooked arm is assembled on the front side board of the cover and is below the observation port, a swing rod of the crooked arm is arranged in the cover and is fixed with a scraper plate or a hairbrush, and a horizontal end portion of the crooked arm outside the cover is connected with a handle. The density relay protection cover has properties of simple structure and relatively low cost, is suitable for use in sandy or dusty areas, can rapidly remove accumulated dusts at an inner wall of the observation window of the protection cover only through poking the handle to drive the crooked arm and the scraper plate to rotate without the need for dismounting the cover for cleaning, reduces workload and improves work efficiency.
Description
Technical field
The utility model relates to transformer substation assisted devices, specifically a kind of density monitor protective cover with cleaning device.
Background technology
Substation equipment needs periodical inspection to safeguard, investigation hidden trouble of equipment, guarantees electric power netting safe running and reliable power supply, the outdoor equipments such as circuit breaker density monitor, although carried out dustproof, rainproof treatment, long-play in poor environment, hands over serious on the damage impact of equipment; User is installed dust cover additional in density monitor outside conventionally, avoids rainwater, the erosion of dust to equipment.The cover body of dust cover generally adopts polymethyl methacrylate material make or set up observation window to facilitate observation.
The northern area of China is dry, dust storm, dust are larger, the outdoor equipment long-time running such as density monitor are in the more environment of dust, dust granules is entered and is made its inner surface filthy by cover body bottom, setting angle reason and electrostatic interaction due to density monitor body display window, dusts etc. are attached to dust cover inwall mostly, cause normally reading the pressure data of relay.And assembling is compact between density monitor and dustproof encloser, under installment state, be difficult to cleaning, therefore cover body can only be taken off, carry out wiping, whole operating process approximately needs ten minutes, waste time and energy, and the wiring of the density monitor of very likely damaging, to maintenance work, caused inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of density monitor protective cover with cleaning device, has solved the problem that the inner dust stratification of existing dust cover cannot be observed.
The technical solution of the utility model: comprise cover body, crank arm, handle; Cover body is the quadrangle housing that Open Side Down, and the lower limb of housing is provided with draw-in groove; The front side board of cover body is provided with observation port, and observation port frame is embedded with transparent panel; Be positioned on the front side board of observation port below and have fixing hole; Two sections of bodies of rod of cranking arm are mutually vertical, and the horizontal segment body of rod of cranking arm passes fixing hole and is arranged on cover body front side board by nut and shell fragment; On the wobble segment body of rod of cranking arm, be fixed with scraper plate or hairbrush; Be positioned at the horizontal segment end connecting handle of cranking arm of cover body outside.
Further, described in scraper plate on cranking arm or hairbrush towards observation port one side, scraper plate or hairbrush coordinate with the transparent panel of observation port.
Further, described in the crank arm both sides, front and back of the wobble segment body of rod be all fixed with scraper plate or hairbrush, scraper plate or hairbrush coordinate with the transparent panel of observation port and the display window of circuit breaker density monitor respectively.
The utility model has the advantages that: simple in structure, cost is lower, applicable dust storm, the area that dust is larger are used, when equipment-patrolling reads density monitor, as the observation window inwall adhesive dust of protective cover, stir handle and drive and to crank arm and scraper plate scrapes the dust stratification of observation window inwall, without pulling down cover body wiping, reduce workload, improved operating efficiency.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the work schematic diagram of the utility model embodiment 2.
Embodiment
In figure: 1, cover body, 2, crank arm, 3, scraper plate, 4, observation port, 5, handle, 6, circuit breaker density monitor.
Embodiment 1
As can be seen from Figure 1, the utility model comprise cover body 1, crank arm 2, handle 4; Cover body 1 is the quadrangle housing that Open Side Down, and the lower limb of housing is provided with the draw-in groove with circuit breaker density monitor support assorted, and cover body 1 is installed on the support of circuit breaker density monitor 6 by draw-in groove, and fixes by screw; The front side board of cover body 1 is provided with observation port 4, and observation port 4 frames are by pasting the organic glass transparent panel of setting-in; Be positioned on the front side board of observation port 4 belows and have fixing hole; 2 the two sections of bodies of rod of cranking arm are mutually vertical, and 2 the horizontal segment body of rod of cranking arm is through fixing hole and be arranged on cover body 1 front side board by nut and shell fragment, and the present embodiment shell fragment adopts disk spring washer; Crank arm on 2 the wobble segment body of rod and be fixed with scraper plate 3(according to the dust stratification situation in cover, also can choice for use hairbrush); Scraper plate 3 is towards observation port 4 one sides, and with the glass transparent panel inner wall close contact of observation port 4; Scraper plate 3 adopts quality of rubber materials, has good elasticity, heat-resisting, cold-resistant, anticorrosive; Under the effect of disk spring washer, scraper plate 3 remains is close to observation port face glass; Be positioned at the horizontal segment rod end connecting handle 5 of cranking arm of cover body 1 outside.
When substation equipment patrol is safeguarded, as it is more to run in protective cover adhesive dust, observation window inwall dust stratification affects data and reads, staff holds handle 5 left and right and stirs, drive crank arm 3 and scraper plate 3(or hairbrush) swing scraper plate 3(or hairbrush) be close to observation windowpane inwall and swing dust stratification is flipped, do not need dismounting cover body to carry out wiping, reduce workload, significantly improved operating efficiency.
Embodiment 2
As shown in Figure 2, the present embodiment difference from Example 1 is: described in the crank arm both sides, front and back of 2 the wobble segment body of rod be all fixed with scraper plate 3(or hairbrush), be scraper plate 3(or hairbrush) respectively towards the transparent panel of observation port 4 and the display window of circuit breaker density monitor 6, and contact cooperation with observation port transparent panel and density monitor display window, stir handle 5 drive crank arm 2 and scraper plate 3(or hairbrush) swing, realize observation port transparent panel and density monitor display window simultaneously clean.
Other features of the present embodiment are identical with embodiment 1.
Finally should be noted that: above embodiment is used for illustrating that the technical solution of the utility model is not intended to limit; those skilled in the art modifies to execution mode or part technical characterictic is equal to replacement; and do not depart from the essence of technical solutions of the utility model, within all should being encompassed in the utility model scope required for protection.
