Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1: the automatic start-stop device of the sweeping pump of the sweeping pool shown in fig. 1 comprises: the device comprises a channel steel frame 1 fixed on the side of a sweeping pool, a high liquid level travel switch 2 and a low liquid level travel switch 3 fixed on the channel steel frame 1 and connected with a controller of a sweeping pump, a top hollow pipe 4 and a bottom hollow pipe 5 respectively fixed at the top end and the bottom end of the channel steel frame, the top hollow pipe 4 and the bottom hollow pipe 5 are coaxially arranged and vertically positioned above the sweeping pool, a thin steel bar stick 6 penetrating through the top hollow pipe 4 and the bottom hollow pipe 5, a buoyancy cylinder 7 fixed at the bottom end of the thin steel bar stick 6, a sealing cover arranged at the top end of the buoyancy cylinder, a plectrum 8 fixed on the thin steel bar stick 6, and the plectrum 8 positioned between the high liquid level travel switch 2 and the low liquid level travel switch 3. A plurality of adjusting holes 9 are arranged on the groove steel frame 1 along the vertical direction.
The floor sweeping pool is positioned below the ground, a buoyancy cylinder is arranged at the liquid level of the floor sweeping pool, the buoyancy cylinder floats according to the height of the liquid level of the floor sweeping pool, the buoyancy cylinder drives a thin steel bar rod to move up and down when floating, and the thin steel bar rod triggers a high liquid level travel switch or a low liquid level travel switch in the process of moving up and down, and the high liquid level travel switch or the low liquid level travel switch starts and stops a floor sweeping pump. The sweeping pump is automatically started and stopped through the liquid level high-low induction, so that the phenomenon that a worker observes the liquid level of a sweeping pool all the time is avoided, the labor intensity of the worker is reduced, and the phenomenon that the sweeping pump runs under the condition of material overflow or low liquid level due to untimely monitoring is avoided.
The transmission part is arranged as a thin steel bar rod, the thin steel bar rod is limited in the top hollow pipe and the bottom hollow pipe, so that the thin steel bar rod can be prevented from shaking, and meanwhile, the buoyancy cylinder can be lifted or lowered along with the lifting or lowering of the liquid level in the sweeping pool, so that a high liquid level travel switch or a low liquid level travel switch is triggered at a set position.
The whole structure can be manufactured by utilizing the existing parts, and the structure is simple, easy to manufacture, firm and durable. The buoyancy cylinder is a cylinder body, and compared with other buoyancy blocks, the buoyancy cylinder is easier to float at the liquid level of the sweeping pool, and the liquid level difference is avoided.
The top end of the buoyancy cylinder is provided with the sealing cover, the buoyancy cylinder is more convenient to be used as a sealing body when being connected, and liquid in the sweeping pool is prevented from entering the buoyancy cylinder. The top end of the buoyancy cylinder is open, and the buoyancy cylinder can be used by directly taking materials locally. The top hollow pipe and the bottom hollow pipe are hollow iron pipes, so that the materials are convenient to obtain and the hollow iron pipes can be directly utilized.
Example 2: as shown in fig. 2, the difference from embodiment 1 is that the thin steel bar rod 6 is replaced with a wire rope 61, a pulley block 62 and a weight 63, and the other structure is unchanged. The pulley block 62 is fixed on the top of the groove steel frame 1, one end of the steel wire rope 61 is connected with the buoyancy cylinder 7, the other end of the steel wire rope 61 passes through the top hollow pipe 4 and the bottom hollow pipe 5 and then falls down through the pulley block 62, the balancing weight 63 is connected with the other end of the steel wire rope 61, and the balancing weight 63 straightens the steel wire rope and enables the buoyancy cylinder to be positioned at the liquid level of the sweeping pool. The weight of the balancing weight is slightly smaller than the weight of the buoyancy cylinder no matter where the buoyancy cylinder is positioned on the liquid surface, and the balancing weight straightens the steel wire rope to enable the buoyancy cylinder to be kept on the liquid surface.
The wire 61 changes its pulling direction by means of the pulley block 62 and is kept in a straightened state by means of the counterweight 63. In the example 2, the buoyancy cylinder is moved up and down to pull the flexible wire rope, and the wire rope, the pulley block and the counterweight block are utilized, but the wire rope is in a straightened state, and the limit of the top hollow tube 4 and the bottom hollow tube 5 is added to ensure that the high-liquid-level travel switch or the low-liquid-level travel switch is triggered when the wire rope moves up and down.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
