Description

Technical Field

[0001] The present invention relates to the field of landscape-type underground prefabricated substations, and in particular to a visual pit cover for landscape-type underground prefabricated substations. Background Art

[0002] Due to the continuous advancement of urbanization and smart city construction, in order to solve the problems of large land occupation, waste of land resources, single style, inability to integrate into the surrounding environment, and radiation of transformers, some cities use landscape-style underground box transformers to replace some conventional box transformers, that is, the transformers are moved underground, thereby reducing the floor space required for the box transformers and the radiation problem of the transformers.

[0003] During normal use, power distribution products must be inspected regularly to ensure that no problems occur during operation. However, during the use of conventional landscape-type underground transformers, since the transformer is located underground, during normal inspections, if you check the operating status of the transformer, you must open the transformer inspection cover to observe the operating status of the transformer. However, due to the influence of the structure, the transformer inspection cover cannot be large enough to fully observe the operating status of the transformer, and can only observe the partial operating status of the transformer. If you want to observe the overall operating status of the transformer, personnel must go down to the underground transformer room. However, since the transformer is in operation at this time, there is a great safety hazard for personnel to go down to the transformer room. Utility Model Content

[0012] Technical effects and advantages of the present invention:

[0013] 1. The visual pit cover of the landscape-type buried prefabricated substation.

DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and actual construction. The following actual construction is only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] The present invention provides Figure 1-3 The illustrated visual pit cover for landscape-type underground prefabricated substation comprises a first high-strength frame 1, a door lock 7 fixedly connected to one end of one side of the inner wall of the first high-strength frame 1, a drain pipe 9 fixedly connected to the other end of one side of the inner wall of the first high-strength frame 1, and a drain pipe 9 is installed at a suitable position to ensure that rainwater does not flow into the pit, and the accumulated rainwater is discharged to the outside of the equipment through the drain pipe 9, thereby ensuring the operating environment of the transformer, the middle of one side of the first high-strength frame 1 is fixedly connected to one side of the second high-strength frame 2, the first high-strength frame 1 and the second high-strength frame 2 are welded with square tubes and channel steels with high corrosion resistance, the specifications of the square tubes and channel steels are selected, and the pressure per unit area is strictly calculated after force analysis, and the data obtained finally confirms the installation position, after confirming the position, the square tubes and channel steels are welded together by welding, and a square maintenance groove 14 is opened on one side of the top of the second high-strength frame 2, The two sides in the middle of the second high-strength skeleton 2 are hinged to the two ends of one side of the maintenance man cover 6 through damping hinges, and the four sides of the bottom end of the maintenance man cover 6 are fixedly connected to one side of the square connecting frame 15, and the two ends of one side of the square maintenance groove 14 are fixedly connected with gas struts 8. After the door lock 7 is opened, the built-in gas struts 8 will automatically bounce the maintenance man cover 6 to 70°. After bouncing up, the two L-shaped limit rods 4 are fixed in the specified position to ensure that the maintenance man cover 6 cannot move. Personnel go down to the inside of the pit to maintain and replace damaged components. The two gas struts 8 can be started at the same time through the connected external power, and the middle of the adjacent side of the square maintenance groove 14 is rotatably connected to one end of the outer wall of the L-shaped limit rod 4, and the tops of the two gas struts 8 push rods are respectively in contact and connected with the two top corners of the inner wall of the square connecting frame 15, and the tops of the outer walls of the two L-shaped limit rods 4 are respectively rotatably connected with the two bottom corners of the inner wall of the square connecting frame 15;

[0023] The present invention provides Figure 2-3The illustrated visualization pit cover for landscape-type underground prefabricated substation has two ends on the other side of the top of the second high-strength frame 2 fixedly connected with the first tempered glass 12, and the four corners of the top of the second high-strength frame 2 are fixedly connected with the second tempered glass 10. The top of the maintenance cover 6 is fixedly connected with the third tempered glass 11. The surface of the second high-strength frame 2 uses the first tempered glass 12, the second tempered glass 10 and the third tempered glass 11 as visualization forms. Considering the use environment and other factors, three layers of ultra-white tempered glass are used with SG added inside. P film can ensure the safety of people walking on it. The operating personnel, based on the weight and volume of multiple pieces of first tempered glass 12, second tempered glass 10 and third tempered glass 11, strictly calculate the pressure exerted on the first high-strength frame 1 and the second high-strength frame 2 per unit area and the pressure that the first high-strength frame 1 and the second high-strength frame 2 need to withstand through force analysis, and finally determine the overall structural layout of the first high-strength frame 1 and the second high-strength frame 2. After the determination is completed, select suitable square tubes and channel steels with high corrosion resistance to weld them together. The top of the second high-strength frame 2 is fixed with structural glue 3 on the outside, and the top of the second high-strength frame 2 is fixed with rubber pads 5 on the inside. After the first high-strength frame 1 and the second high-strength frame 2 are welded, rubber pads 5 are laid on the surface of the metal parts. After the rubber pads 5 are laid, use professional tools to install multiple first tempered glasses 12, second tempered glasses 10 and third tempered glasses 11 one by one at the designated positions. After the installation is completed, fill the surrounding areas with structural glue 3 to prevent the tempered protective glass from sliding and damage due to transportation and other problems, ensuring the installation of steel in the later stage When the protective glass is welded, the problem of breakage due to contact between the glass and the metal parts occurs. After welding is completed, since the tempered protective glass is installed on the surface of the square tube, a special protective rubber pad 5 must be pasted on the surface of the square tube before the tempered protective glass can be placed on the upper part of the frame. After placement, the surrounding area is filled with special structural glue 3 for tempered protective glass to ensure that the tempered protective glass will not be directly connected to the steel structure profile. The two ends of the other side of the second high-strength frame 2 are fixedly connected with square connectors 13, and one end of each side of the two square connectors 13 is provided with a connecting hole to facilitate the auxiliary fixation of the second high-strength frame 2.

[0024] The working principle of the present invention is as follows: when the lock 7 is opened, the two gas struts 8 installed inside automatically pop up the square connecting frame 15. After the square connecting frame 15 pops up, it drives the middle part of the hinged pit cover plate dedicated to the maintenance cover plate 6 to pop up. After popping up, the two L-shaped limit rods 4 of the maintenance cover plate 6 are fixed to specific positions to ensure that the maintenance cover plate 6 cannot move. Later, the personnel go down to the inside of the pit through the square maintenance groove 14 to replace the damaged components.
