Description

Technical Field

[0001] This utility model relates to the field of power cable equipment technology, specifically a cement cover plate for power cable wells. Background Technology

[0002] Cement covers for power cable wells are building products used in the construction of power facilities. They are mainly used to cover cable wells to protect cables and other electrical equipment from damage by the external environment and to ensure safety and unobstructed access for maintenance.

[0003] For example, a cement cover for a power cable well, with announcement number "CN211547822U," uses a wear-resistant outer shell to protect the wireless radio frequency antenna and employs an internal groove to connect and fix the antenna to the cement cover body, effectively extending the antenna's lifespan and reducing maintenance costs. It also features hard bristles on the inside of the feeder socket, angled downwards towards the cement cover body, preventing the feeder cable from protruding from the cover body and affecting its lifespan. However, in this particular cement cover for a power cable well, the wireless radio frequency antenna is connected to the cover body via an internal groove. When pedestrians step on it or vehicles run over it, vibrations and misalignment can easily occur, affecting the transmission direction and strength of the wireless signal. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when a wireless radio frequency antenna is connected to the cement cover plate body through an inner groove, it is easy to cause vibration and displacement when pedestrians step on it or vehicles run over it, which affects the transmission direction and strength of the wireless signal. Therefore, a cement cover plate for power cable wells is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cement cover for a power cable well is designed, comprising a horizontal plate and a wireless radio frequency antenna. The wireless radio frequency antenna is provided on the top of the horizontal plate, and mounting structures are provided on both sides of the wireless radio frequency antenna. The mounting structures include mounting plates and limiting grooves. The inner side of the mounting plate is fixedly connected to the wireless radio frequency antenna. The outer side of the inner wall of the mounting plate is machined with a first threaded hole. The inner walls of the first threaded hole and the second threaded hole are threaded with bolts. The inner side of the inner wall of the mounting plate is machined with a groove. The limiting groove is machined in the middle of the inner wall of the horizontal plate.

[0007] Preferably, the second threaded holes are all machined on the inner side of the inner wall of the horizontal plate, and the inner side of the limiting groove is in contact with the wireless radio frequency antenna and the mounting plate.

[0008] Preferably, a through hole is machined below the limiting groove.

[0009] Preferably, the wireless radio frequency antenna is electrically connected to the connecting feeder below.

[0010] Preferably, the lower part of the connecting feeder is electrically connected to the feeder connector.

[0011] The present invention proposes a cement cover plate for power cable wells, which has the following advantages: by cooperating with the horizontal plate and the mounting structure, the wireless radio frequency antenna is placed in the limiting groove, and the connecting feed line passes through the first through hole. Then, by rotating multiple bolts, the ends of the bolts are screwed into the first threaded hole and the second threaded hole in sequence, thereby fixing the mounting plate and the wireless radio frequency antenna in the limiting groove. This allows the horizontal movement of the wireless radio frequency antenna to be restricted by the limiting groove, and the vertical movement of the wireless radio frequency antenna to be restricted by the bolts, making the installed wireless radio frequency antenna more stable and reducing the impact on the transmission direction and strength of the wireless signal.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6In this embodiment, a cement cover plate for a power cable well includes a horizontal plate 1 and a wireless radio frequency antenna 2. The wireless radio frequency antenna 2 is provided on the top of the horizontal plate 1. The wireless radio frequency antenna 2 is a model HX-PCBNFC-2821 wireless radio frequency antenna. The wireless radio frequency antenna 2 is provided on both sides with mounting structures 3. The mounting structure 3 includes a mounting plate 301 and a limiting groove 306. The inner side of the mounting plate 301 is fixedly connected to the wireless radio frequency antenna 2. The outer side of the inner wall of the mounting plate 301 is machined with a first threaded hole 303. The inner walls of the first threaded hole 303 and the second threaded hole 304 are threadedly connected to bolts 305. The inner side of the inner wall of the mounting plate 301 is machined with a groove 302. The limiting groove 306 is machined in the middle of the inner wall of the horizontal plate 1.

[0021] The second threaded holes 304 are all machined on the inner side of the inner wall of the horizontal plate 1 (the horizontal plate 1 is made of cement and usually has a steel mesh inside, so the second threaded holes 304 can be machined on the steel mesh). The inner side of the limiting groove 306 is in contact with the wireless radio frequency antenna 2 and the mounting plate 301. A through hole 8 is machined below the limiting groove 306. The lower part of the wireless radio frequency antenna 2 is electrically connected to the connecting feeder 5, and the lower part of the connecting feeder 5 is electrically connected to the feeder connector 6.

[0022] Working principle:

[0023] When using cement covers for power cable wells:

[0024] The operator places the wireless radio frequency antenna 2 (which transmits wireless signals to achieve wireless signal transmission) into the limiting groove 306, and passes the connecting feeder 5 through the first through hole 8. Then, the operator rotates multiple bolts 305, causing the ends of the bolts 305 to be screwed into the first threaded hole 303 and the second threaded hole 304 in sequence. This fixes the mounting plate 301 and the wireless radio frequency antenna 2 in the limiting groove 306. The limiting groove 306 restricts the horizontal movement of the wireless radio frequency antenna, and the bolts 305 restrict the vertical movement of the wireless radio frequency antenna 2, making the installed wireless radio frequency antenna 2 more stable and reducing interference with the wireless signal. The transmission direction and intensity are affected, and then the feeder connector 6 is connected to the passive sensor in the power cable well, which will enable the wireless sensor to communicate normally and ensure the transmission of wireless signals. The wireless signals are transmitted to the monitoring center, and at the same time, the wireless radio frequency antenna 2 can receive instructions from the monitoring center to remotely control and manage the equipment in the power cable well. Then, the operator inserts multiple fastening bolts and the through holes at the four corners of the horizontal plate 1 (the horizontal plate 1, the wireless radio frequency antenna 2, the second through hole 7, etc. are the main structures of the cement cover plate of the cable well, and the material of the horizontal plate 1 is cement) into the bolts corresponding to the opening of the power cable well, and then rotates the nut to fix the horizontal plate 1 above the power cable well.

[0025] When the wireless radio frequency antenna 2 is damaged and needs to be disassembled for repair, the operator first rotates the fastening bolts at the four corners of the horizontal plate 1 to remove the horizontal plate 1. Then, disconnect the feeder connector 6, rotate multiple bolts 305 so that the ends of the bolts 305 are unscrewed from the second threaded hole 304 and the first threaded hole 303. Then, reach into the groove 302 and remove the wireless radio frequency antenna 2.

[0026] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
