Description

Technical Field

[0001] The utility model relates to the technical field of water pumps for measuring underground water levels, and more specifically, to a water pump for measuring underground water levels. Background Art

[0002] In the current field of groundwater level measurement, water pumps are an indispensable key equipment. They are mainly used to extract groundwater from wells to the ground in order to measure and monitor the water level. However, the existing water pumps for groundwater level measurement still face some problems that need to be solved in practical applications, among which the most prominent is the waterproof sealing problem of water pumps. Due to the particularity of groundwater level measurement, water pumps need to be immersed in groundwater for a long time to work. This puts high demands on the waterproof performance of water pumps. If the cables and pump bodies of water pumps cannot be effectively sealed, moisture will penetrate into them, leading to serious safety hazards such as leakage and short circuit. Once such an accident occurs, it will not only damage the water pump and affect the normal progress of the measurement work, but it is also likely to threaten the lives of on-site workers.

A hexagonal sleeve 12 is coaxially provided on the telescopic tube 7, and the hexagonal sleeve 12 is threadedly connected to the wire clamping tube 3. A plurality of guide strips 13 are equidistantly provided on the side walls of the two pressing sleeves 5, and a plurality of lateral grooves 14 are provided on the inner wall of the wire clamping tube 3. The guide strips 13 are slidably connected in the lateral grooves 14. The connecting mechanism includes a sealing ring 15 and a rubber ring 16. A fixing hole 17 and a sealing groove 18 are provided on the pump body 1, and the wire clamping tube 3 is threadedly connected in the fixing hole 17. The sealing ring 15 is installed on the side wall of the wire clamping tube 3, and the sealing ring 15 abuts in the sealing groove 18. A rubber ring 16 is installed on the sealing ring 15, and the rubber ring 16 abuts in the sealing groove 18. A hexagonal section 19 is provided on the side wall of the wire clamping tube 3, and the hexagonal section 19 fits on the sealing ring 15.

[0029] In this embodiment, when fixing the cable, first, the connection between the wire clamping tube 3 and the pump body 1 is ensured by connecting the rubber ring 16, multiple sealing rings and the sealing groove 18. Since the cable passes through the wire clamping tube 3 and is electrically connected to the pump body 1, and since the hexagonal sleeve 12 is threadedly connected to the wire clamping tube 3, the compression spring 6 on the telescopic tube 7 is pressed on the compression sleeve 5, so that the multiple rubber strips 4 are squeezed against each other. The setting of the compensation groove 8 ensures that the rubber strips 4 are conveniently retracted. Then, the receiving grooves 9 and the fitting grooves 10 on the two adjacent rubber strips 4 fit each other. Then, when the squeezing continues, the multiple rubber strips 4 have a tendency to press the receiving grooves 9 and the fitting grooves 10 to move inward and outward. Since the outer side of the rubber strip 4 contacts the inner wall of the wire clamping tube 3, it can only move in the direction of the axis. Then, the multiple rubber strips 4 are simultaneously contacted with the cable, and the sealing strip 11 is fitted on the adjacent rubber strips 4. As the pressure increases, the seal of the rubber strip 4 becomes closer and closer, so the seal between the rubber strip 4 and the cable becomes tighter and tighter, thereby ensuring the sealing effect.

[0030] See also Figure 1As an implementation of the receiving mechanism: the receiving mechanism includes a water outlet pipe 20 and a support frame 21, the support frame 21 is installed on the lower end surface of the pump body 1, the water outlet pipe 20 is connected to the pump body 1, the pump body 1 is provided with a handle 22, and the pump body 1 is threaded with a hook 23.

[0031] More specifically, after the sealing is completed, the pump body 1 is placed on the groundwater position through the hook 23, and then the pump body 1 is started. At the same time, the support frame 21 supports the pump body 1, thereby ensuring the convenient extraction of groundwater. Then the corresponding measurement process can be carried out, thereby ensuring the continuity of use.

[0032] In summary, when the overall equipment is in use or running: when fixing the cable, firstly, the connection between the wire clamping tube 3 and the pump body 1 is ensured by connecting the rubber ring 16, the multiple sealing rings and the sealing groove 18. Since the cable passes through the wire clamping tube 3 and is electrically connected to the pump body 1, and since the hexagonal sleeve 12 is threadedly connected to the wire clamping tube 3, the compression spring 6 on the telescopic tube 7 is pressed on the compression sleeve 5, so that the multiple rubber strips 4 are squeezed against each other. The convenient expansion and contraction of the rubber strips 4 is ensured by the setting of the compensation groove 8, and then the receiving grooves 9 on the two adjacent rubber strips 4 are boxed. The fitting grooves 10 fit together, and when the squeezing continues, the multiple rubber strips 4 tend to press the receiving grooves 9 and the fitting grooves 10 to move inward and outward. Since the outer side of the rubber strip 4 is in contact with the inner wall of the wire clamping tube 3, it can only move in the direction of the axis, and then the multiple rubber strips 4 are in contact with the cable at the same time, and the sealing strip 11 is in contact with the adjacent rubber strips 4. As the pressure increases, the seal of the rubber strip 4 becomes closer and closer, so the seal between the rubber strip 4 and the cable becomes tighter and tighter, thereby ensuring the sealing effect.

[0033] After the sealing is completed, the pump body 1 is placed on the groundwater position through the hook 23, and then the pump body 1 is started. At the same time, the support frame 21 supports the pump body 1, thereby ensuring the convenient extraction of groundwater. Then the corresponding measurement process can be carried out, thereby ensuring the continuity of use.
