Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 and 2, an inspection well water closing test device comprises a rubber cushion block 2 arranged at the top and the bottom of an inspection well 1, wherein an upper blocking plate 3 is arranged on the upper surface of the rubber cushion block 2 at the top of the inspection well 1, a lower blocking plate 4 is arranged on the lower surface of the rubber cushion block 2 at the bottom of the inspection well 1, a water inlet pipe 5 is arranged on the rubber cushion block 2 at the bottom of the inspection well 1 and the lower blocking plate 4 in a penetrating manner, a water inlet valve 6 and a water pressure detection meter 7 are arranged on the water inlet pipe 5, a water outlet pipe 8 is arranged on the rubber cushion block 2 at the top of the inspection well 1 and the upper blocking plate 3 in a penetrating manner, a water outlet valve 9 is arranged on the water outlet pipe 8, and.

Preferably, the bottom of the water outlet pipe 8 is provided with a filter screen 11, and a floating ball 12 is arranged in the water outlet pipe 8. After the design like this, after the water level rose to filter screen 11 position, water passed through filter screen 11 and entered into in outlet pipe 8 to make floater 12 also rise thereupon, finally when floater 12 rose to the inspection shaft 1 outside in the outlet pipe 8, can be clear through outlet pipe 8 direct observation, outlet pipe 8 can choose transparent toughened glass material for use in this embodiment, can clearly observe whether floater 12 emits the inspection shaft 1 outside like this.

Preferably, the inspection well 1 is provided with a plurality of inspection wells, and a sealing rubber ring 13 is arranged in a gap at the joint of the inspection wells 1. The sealing rubber ring 13 can effectively prevent water leakage at the gap of the splicing position of the inspection wells 1.

Preferably, the clamping device 10 comprises a U-shaped plate 10.1, the upper end and the lower end of the U-shaped plate 10.1 are both in threaded connection with a screw 10.2, a rotating handle 10.3 is arranged at the top of the screw 10.2, and the bottom of the screw 10.2 is connected with a pressure plate 10.5 through a bearing 10.4. When the rotating handle 10.3 is rotated, the screw rod 10.2 is driven to rotate together, and the screw rod 10.2 is in threaded connection with the upper end and the lower end of the U-shaped plate 10.1, so that the screw rod 10.2 can move up and down, and the bearing 10.4 and the pressing plate 10.5 are driven to move up and down, when the bearing 10.4 and the pressing plate 10.5 press the upper blocking plate 3 or the lower blocking plate 4, the bearing 10.4 enables the screw rod 10.2 to be in rotary connection with the pressing plate 10.5, so that the pressing plate 10.5 cannot rotate when pressing the upper blocking plate 3 or the lower blocking plate 4. Preferably, the number of the U-shaped plates 10.1 in this embodiment is two, and the two U-shaped plates are symmetrically arranged.

Preferably, a rubber sheet 10.6 is further arranged on one side surface of the pressure plate 10.5. The rubber sheet 10.6 can prevent the pressing plate 10.5 from damaging the upper blocking plate 3 or the lower blocking plate 4 in the process of pressing the upper blocking plate or the lower blocking plate.

Preferably, the top surface and the bottom surface of the U-shaped plate 10.1 are both provided with screw holes 10.7 matched with the screw rods 10.2, a plurality of insertion holes 10.8 are annularly distributed on the positions of the screw holes 10.7, the rotating handle 10.3 is provided with a bolt 10.9 in a penetrating manner, and the bolt 10.9 is matched with the insertion holes 10.8. Because the water pressure in the inspection well 1 is high during the water closing test, the screw 10.2 and the U-shaped plate 10.1 may loosen or rotate relatively, and in order to prevent this, the plug 10.9 may be inserted into the insertion hole 10.8, so that the relative rotation between the screw 10.2 and the U-shaped plate 10.1 may be avoided.

The working principle of the embodiment is as follows:

at first splice a plurality of inspection shafts 1 and install rubber packing 13 in concatenation gap department together, then set up rubber cushion 2 respectively in 1 upper and lower both sides of inspection shaft, then set up closure plate 3 and lower closure plate 4 again, the tight closure plate 3 of going up of rethread clamping device 10 clamp and lower closure plate 4, concrete operation process is: the rotating handle 10.3 is rotated to drive the screw rod 10.2 to rotate together, the screw rod 10.2 moves, so that the bearing 10.4 and the pressing plate 10.5 are driven to approach towards the upper blocking plate 3 or the lower blocking plate 4, when the bearing 10.4 and the pressing plate 10.5 press the upper blocking plate 3 or the lower blocking plate 4, the rotating handle 10.3 is continuously rotated, so that the pressing plate 10.5 presses the upper blocking plate 3 or the lower blocking plate 4, then the plug pin 10.9 is inserted into the jack 10.8, and the relative rotation between the screw rod 10.2 and the U-shaped plate 10.1 is avoided; then the water inlet valve 6 on the water inlet pipe 5 is opened to lead water into the inspection well 1, when the water level rises to the position of the filter screen 11, the water passes through the filter screen 11 and enters the water outlet pipe 8, and the floating ball 12 also rises along with the water level, finally, when the floating ball 12 in the water outlet pipe 8 rises to the outer side of the inspection well 1, the water can be directly observed and clearly observed through the water outlet pipe 8, at the moment, the air in the inspection well 1 is completely discharged, then the water outlet valve 9 on the water outlet pipe 8 is closed, the water is continuously filled into the inspection well and the water pressure detection meter 7 is observed, the water inlet valve 6 is closed after the pressure is increased to 0.1MPa, the constant pressure is kept for 5min, whether the surface of the inspection well has water leakage phenomenon or not is observed in the period, and the record is made, and.

The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope.
