Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to a monitoring device in a metering station which is convenient for maintenance. Background Art

[0002] Generally, an offshore booster station is configured for a wind farm. After the submarine cables of the wind farm are aggregated, they are stepped up by the offshore booster station and then landed and connected to an onshore metering station. Buildings (structures) such as an annex building, a production auxiliary building, a production building, a power frequency equipment building, a low-frequency equipment building, and an accident oil pool are arranged in the metering station. However, the metering station has problems such as being not suitable for long-term residence and inconvenient for maintenance. Therefore, multiple monitoring devices are generally arranged in the metering station to monitor the situation inside the station, so as to facilitate timely fire protection or equipment maintenance and other measures. Therefore, the monitoring equipment needs to be maintained and replaced regularly. However, the existing monitoring devices are relatively inconvenient to maintain or replace. Content of the Utility Model

[0003] The purpose of the utility model is to provide a monitoring device in a metering station which is convenient for maintenance, which can facilitate the disassembly and maintenance of the monitoring equipment and is easy to operate.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A monitoring device in a metering station which is convenient for maintenance, comprising a mounting rack and a monitoring main body; a vertical sliding track is arranged on the mounting rack, the monitoring main body is slidably connected to the mounting rack up and down along the sliding track, two hooks are rotatably connected to the mounting rack, grooves with downward openings are arranged on both sides of the monitoring main body, and the free ends of the hooks are inserted upward into the grooves.

[0006] By adopting the above technical solution, the monitoring main body is restricted to move only up and down through the sliding track, and the hooks are hooked in the grooves on both sides of the monitoring main body to bear its weight, so that the monitoring main body is stably positioned on the sliding track and the hooks by its own weight. When disassembling, only need to push the monitoring main body upward with one hand, push the hook outward with the other hand, and then take out the monitoring main body downward.

[0007] Furthermore, a limiting groove is also arranged on the mounting rack, a limiting block is slidably connected to the monitoring main body in the horizontal direction, and the limiting block slides inward and is inserted into the limiting groove.

[0008] By adopting the above technical solution, the upward movement of the monitoring main body is further restricted, and the stability of the position of the monitoring main body is improved to reduce problems such as picture jitter.

[0009] Furthermore, the limiting block is connected to the lower side of the monitoring main body, and the upper side surface of the limiting block abuts against the lower side of the upper side edge of the limiting groove.

[0010] By adopting the above technical solution, the monitoring body is restricted from moving upward by the limit block, but does not bear the self-weight of the monitoring body.

[0011] Furthermore, two outer side plates are also connected to the mounting frame. The two outer side plates are respectively located outside the corresponding hooks, restricting the maximum rotation angle of the hooks from rotating outward. The maximum rotation angle is for the hooks to open outward and place the monitoring body.

[0012] By adopting the above technical solution, the maximum rotation angle of the hooks from rotating outward is restricted, for the hooks to open outward and place the monitoring body, which is convenient for operation.

[0013] Furthermore, two vertical plates are connected to the mounting frame. The hook includes a transverse rod at the top. The inner end of the transverse rod is hinged to the outside of the corresponding vertical plate, and the outer end is connected to the main body of the hook.

[0014] By adopting the above technical solution, the setting of the transverse rod enables the hook to tend to close inward under its own weight, improving the convenience of installing the monitoring body. During installation, after pushing open the two hooks, the monitoring body can be pushed upward. The hooks automatically close under their own weight, and when the monitoring body is lowered, its groove can be inserted into the hook to complete the fixation.

[0015] Furthermore, a cross plate is connected to the outside of the lower end of the vertical plate. The cross plate is located below the transverse rod, restricting the minimum rotation angle of the hook from rotating inward. The minimum rotation angle is for the hook to close inward and make its free end insert upward into the groove of the monitoring body.

[0016] By adopting the above technical solution, restricting the minimum rotation angle of the hook from rotating outward. After the monitoring body moves to the uppermost position, the hooks close together under their own weight until their transverse rods abut against the upper side of the cross plate. At this time, when the monitoring body is lowered, its groove is aligned with the free end of the hook for insertion.

[0017] Furthermore, chamfers or inclined plates are provided on both sides of the top of the monitoring body. While the monitoring body slides upward, the lower ends of the hooks are pushed outward by the chamfers or inclined plates.

[0018] By adopting the above technical solution, it further facilitates the installation work of the monitoring body. During installation, when the monitoring body is moved upward, the hooks can be pushed open by its own chamfers or inclined plates.

[0019] Furthermore, the monitoring body includes an extension frame and a monitoring head. The monitoring head is pre-removably connected to the extension frame. The extension frame is slidably connected to the mounting frame and is provided with a groove.

[0020] By adopting the above technical solution, it is convenient for fixing and opening various structures on the monitoring body, and is suitable for various monitoring head devices.

[0021] In summary, the present utility model has the following beneficial effects:

[0022] The monitoring body is restricted to move up and down through the sliding track. The hooks are hooked in the grooves on both sides of the monitoring body to bear its weight, so that the monitoring body is stably positioned on the sliding track and the hooks by its own weight. When disassembling, only need to push the monitoring body upward with one hand, push the hooks outward with the other hand, and then take out the monitoring body downward. It also sets a limit groove to further restrict the upward movement of the monitoring body, improving the stability of the monitoring body position and reducing problems such as picture jitter.

[0023] The two outer side plates limit the maximum rotation angle of the hooks to rotate outward, for the hooks to open outward and put the monitoring body in, which is convenient for operation. The horizontal plate limits the minimum rotation angle of the hooks to rotate inward, for the hooks to close inward and make their free ends insert upward into the grooves of the monitoring body. After the monitoring body moves to the uppermost position, the hooks close to each other under the action of their own weight until their cross bars abut against the upper side of the horizontal plate. At this time, lower the monitoring body, and its grooves will be aligned with the free ends of the hooks for insertion, improving the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following further describes the specific embodiments of the present invention with reference to the drawings. This embodiment does not constitute a limitation to the present invention. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0029] A monitoring device in a metering station that is convenient for maintenance, such as Figure 1As shown, it includes a mounting bracket 1 and a monitoring main body 2; a connecting plate is fixed on the wall, the connecting plate is connected to the mounting bracket 1 by bolts, the monitoring main body 2 is detachably connected to the mounting bracket 1, the monitoring main body 2 includes an extension bracket 21 and a monitoring head 22, the monitoring head 22 is pre-detachably connected to the extension bracket 21, and it can be installed by existing methods such as screws. Different extension bracket 21 structures can be replaced according to different monitoring heads 22 or installation environments. The monitoring head can be wired through a nearby plug or the like, which is convenient for direct disassembly and replacement.

[0030] As Figure 1 and Figure 2 shown, vertically and symmetrically arranged sliding tracks 11 are fixed on the mounting bracket 1, and the extension bracket 21 is slidably connected to the mounting bracket 1 along the sliding tracks 11 up and down. The cross-section of the sliding tracks 11 can be L-shaped or U-shaped. The inner end of the extension bracket 21 can be welded to sliding plates that slide in the two sliding tracks 11 on both sides respectively, so as to realize the up and down sliding of the extension bracket 21;

[0031] Two hooks 3 are also rotatably connected to the mounting bracket 1. Grooves 211 opening downward are formed on both sides of the bottom plate of the extension bracket 21. An L-shaped hook is integrally connected to the inner side of the free end of the hook 3, so that the top of the L-shaped hook structure is inserted upward into the groove 211 to bear the gravity of the extension bracket 21.

[0032] As Figure 2 shown, in order to limit the rotation angle of the hook 3, two outer side plates 4 are also fixed on the sliding tracks 11 of the mounting bracket 1. The two outer side plates 4 are respectively located outside the corresponding hooks 3 to limit the maximum rotation angle of the hook 3 rotating outward. The maximum rotation angle is for the hook 3 to open outward and put the monitoring main body 2 in. The outer side plates 4 can be set as magnets or suction cups to adsorb the hook 3, which is convenient for disassembly work;

[0033] Two U-shaped frames are also fixed on the sliding tracks 11. The U-shaped frame includes a vertical plate 5 and parallel plates at the upper and lower ends of the vertical plate 5. The lower parallel plate is a horizontal plate 51. The hook 3 includes a transverse rod 31 integrally connected at the top. The inner end of the transverse rod 31 is hinged to the outside of the corresponding vertical plate 5, and the outer end is integrally connected to the main body of the hook 3; the horizontal plate 51 at the lower end of the vertical plate 5 is located below the transverse rod 31 to limit the minimum rotation angle of the hook 3 rotating inward. The minimum rotation angle is for the hook 3 to close inward and make its free end inserted upward into the groove 211 of the monitoring main body 2;

[0034] In this embodiment, when the hook 3 rotates until its transverse rod 31 abuts against the upper side of the horizontal plate 51, the minimum rotation angle of the hook 3 is reached. At this time, the main body of the hook 3 is vertical, its free end is vertically connected to the L-shaped hook, and the groove 211 is vertically inserted into the L-shaped hook.

[0035] As Figure 2As shown in the figure, chamfers or inclined plates are provided on both sides of the top of the extension frame 21. While the extension frame 21 slides upward, the lower end of the hook 3 is pushed outward by the chamfers or inclined plates. In this embodiment, the extension frame 21 is welded by a U-shaped frame and a straight plate. The U-shaped frame is located on the upper side, and the straight plate is welded to the lower side of the U-shaped frame. The bent part of the U-shaped frame is bent into an arc shape, which corresponds to the position of the hook 3. When the extension frame 21 moves upward, the lower end of the hook 3 is pushed outward by the arc chamfer.

[0036] As Figure 2 As shown in the figure, in order to improve the stability of the extension frame 21 after installation, a limiting groove is also provided on the mounting frame 1. A horizontal sliding groove is connected to the lower side of the bottom plate of the extension frame 21. A limiting block 212 is slidably connected in the horizontal sliding groove along the horizontal direction. The limiting block 212 slides inward and is inserted into the limiting groove.

[0037] Among them, the limiting block 212 is connected to the lower side of the extension frame 21. The upper side of the limiting block 212 abuts against the lower side of the upper side edge of the limiting groove, while there is a gap between the lower side of the limiting block 212 and the lower side plate of the limiting groove, so that the limiting block 212 only restricts the upward movement of the extension frame 21 and does not bear its pressure. Of course, the width of the limiting groove can also be made exactly the same as the thickness of the limiting block 212, and the limiting block 212 can be set thicker to share a certain amount of pressure.

[0038] During installation, the monitoring main body 2 is pushed upward along the sliding track 11, and the lower end of the hook 3 is pushed outward until the lower end of the monitoring main body 2 leaves. Under the action of its own weight (or manually), the hook 3 closes again until the transverse rod 31 abuts against the upper side of the transverse plate 51. Then the monitoring main body 2 is lowered downward. The top of the L-shaped hook structure at the free end of the hook 3 is inserted upward into the groove 211, and the limiting block 212 is slid inward and inserted into the limiting groove.

[0039] During disassembly, the limiting block 212 is slid outward and removed from the limiting groove. The monitoring main body 2 is lifted upward, and the two hooks 3 are opened outward, so that the monitoring main body 2 moves downward and leaves the sliding track 11 to complete the disassembly.

[0040] The above is only a preferred embodiment of the present invention and is not used to limit the present invention. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention. Such modifications or equivalent replacements should also be regarded as falling within the protection scope of the technical solution of the present invention.
