Description

Technical Field

[0001] The utility model relates to the technical field of cable trench drainage, in particular to a cable trench drainage mechanism. Background Art

[0002] If the water in the cable trench is not drained in time, it will cause great safety hazards to the safe operation of the substation system. On the one hand, it will make the equipment damp, affecting the insulation level and operation stability. On the other hand, in case of heavy rainfall, the water level in the cable trench will rise too fast in a short period of time, which may cause the accumulated water to flow back into the distribution room and cause safety accidents.

[0003] A submersible pump is installed in the cable trench to drain water, and a water level meter and corresponding control equipment are used to start the submersible pump to drain water when the water level is too high. However, the water level meter is directly placed in the cable trench, and it floats on the water surface unstably. Pulling the connected cables causes the cables to be pulled, and the end of the cable connected to the junction box is in a pulled state, which is prone to unstable wiring problems.

[0004] In view of this, we propose a cable trench drainage mechanism. Utility Model Content

[0011] The guide block is fixedly arranged on one side of the top of the water level gauge body;

[0012] Wherein, the outer end of the guide block is slidably matched with the guide groove provided on the guide rail.

[0013] Preferably, the guide block is made of polypropylene floating plastic.

[0014] Preferably, the outer end of the guide block is configured to be T-shaped, and the outer end of the guide block is adapted to the guide groove.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model has the advantage of providing a guide rail and a guide block to longitudinally limit the water level meter body as the water level changes, so that the water level meter body remains stable when it moves longitudinally with the water level and does not pull the waterproof cable B, thereby solving the problem of unstable wiring caused by one end of the cable connected to the junction box being in a pulled state.

[0018] 2. The utility model has the advantages of closing the bottom of the guide track by setting a stopper, and the water level meter body moves downward to limit the position. The lowest position of the water level meter body will not contact the bottom of the cable trench, and will not impact and damage the water level meter body. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] Example 1: A cable trench drainage mechanism, see Figures 1 to 4 , including a submersible pump body 1 for draining the cable trench, the submersible pump body 1 is selected and used by the technicians of this profession according to the actual situation, the water outlet of the submersible pump body 1 is arranged with a drainage pipe 2, and also includes a junction box 3, a water level meter body 7, a guide rail 6 and a guide block 8;

[0027] The junction box 3 is fixedly mounted on the top of the inner wall of the cable trench; the junction box 3 is connected to the corresponding external control device PLC controller; wherein, the wiring terminal of the submersible pump body 1 is connected to one wiring terminal of the junction box 3 through a waterproof cable A4; the water level meter body 7 is connected to the other wiring terminal of the junction box 3 through a waterproof cable B5; the water level meter body 7 is selected and used by the technical personnel of this profession according to the actual situation; the guide rail 6 is fixedly mounted on the inner wall of the cable trench; the guide block 8 is fixedly mounted on one side of the top of the water level meter body 7; wherein, the outer end of the guide block 8 is slidably matched with the guide groove 601 provided on the guide rail 6.

[0028] The utility model has the advantage of providing a guide rail 6 and a guide block 8 to longitudinally limit the water level gauge body 7 as the water level changes, so that the water level gauge body 7 remains stable when moving longitudinally with the water level and does not pull the waterproof cable B5, thereby solving the problem of unstable wiring caused by one end of the cable connected to the junction box 3 being in a pulled state.

[0029] Specifically, the guide block 8 is made of polypropylene floating plastic; the guide block 8 can move longitudinally in coordination with the water level meter body 7 as the water level changes.

[0030] Furthermore, the outer end of the guide block 8 is set in a T shape, and the outer end of the guide block 8 is adapted to the guide groove 601. The T-shaped outer end of the guide block 8 is more stable when slidingly matched with the guide groove 601, so that the water level meter body 7 is further kept stable when moving.

[0031] Furthermore, a stopper 9 is fixedly provided at the bottom end of the guide track 6 .

[0032] The utility model has the advantages of closing the bottom of the guide track 6 by setting the stopper 9, and the water level meter body 7 moves downward for limiting, and the lowest position of the water level meter body 7 will not contact the bottom of the cable trench, and will not impact and damage the water level meter body 7.

[0033] Working principle: When using the device of the utility model, the submersible pump body 1 is installed at the bottom of the cable trench, the drainage end of the drain pipe 2 extends from the cable trench and is connected to the external drainage passage, the junction box 3 is fixed to the top of the inner wall of the cable trench, the guide track 6 is fixed to the inner wall of the cable trench, the outer end of the T-shaped guide block 8 slides with the guide groove 601, the wiring terminal of the submersible pump body 1 is connected to one wiring terminal of the junction box 3 through the waterproof cable A4, and the water level meter body 7 is connected to the other wiring terminal of the junction box 3 through the waterproof cable B5.

[0034] The water level gauge body 7 changes with the water level in the cable trench, and the outer end of the guide block 8 moves up along the guide groove 601 as the water level is adjusted. The water level gauge body 7 moves up with the water level and feeds back data to the corresponding external control equipment. When the water level in the cable trench is too high, the submersible pump body 1 starts to discharge the water in the cable trench. The water level gauge body 7 lowers with the water level, and the outer end of the guide block 8 moves down along the guide groove 601 as the water level is adjusted. After the water level gauge body 7 drops to a certain position, the submersible pump body 1 stops.
