Further, as shown in fig. 1, a limit block 3121 is convexly disposed on the side wall of the mounting cavity 312 adjacent to the sliding groove, and the limit block 3121 is located between the lower metal plate 62 and the partition 33 for limiting the lower metal plate 62.
In this embodiment, the position of the two ends of the lower metal plate 62 on the inner side wall of the cavity 31 is limited by the limiting block 3121, so that the lower metal plate 62 does not contact with the rod 5 when the cavity 31 of the floating seat 4 is not filled with water. In addition, because the setting position of the limit block 3121 determines the maximum distance between the lower metal plate 62 and the upper metal plate 61, it also determines how high the lift rod 5 floats, so that the lower metal plate 62 can contact the upper metal plate 61, that is, it determines how high the water level in the float bowl 3 rises, and an alarm is triggered. Therefore, the position of the limiting block 3121 can be set according to actual early warning needs, so that the blocking early warning needs of different urban water conservancy pipelines 2 are met.
Alternatively, as shown in fig. 3, one side of the upper metal plate 61 facing the lower metal plate 62 is provided with an upper contact 611 and a guide post 612 at intervals, and the lower metal plate 62 is provided with a lower contact 621 corresponding to the upper contact 611 and a guide hole 622 corresponding to the guide post 612; the upper contact 611 cooperates with the lower contact 621 to form a contact gap 63; the guide post 612 at least partially passes through the guide hole 622, and the lower metal plate 62 slides along the guide post 612 through the guide hole 622.
In this embodiment, under the cooperation of the guide post 612 and the guide hole 622, the upper contacts 611 correspond to the lower contacts 621 one to one, so that when the lower metal plate 62 moves close to the upper metal plate 61, the lower contacts 621 can be accurately aligned and contacted with the upper contacts 611, the contact between the lower contacts 621 and the upper contacts 611 is ensured to be stable and reliable, and the false contact between the lower contacts 621 and the upper contacts 611 is avoided when the contact is poor or the water level in the float 3 fluctuates, so as to trigger the alarm 72 by mistake to give an alarm.
Alternatively, as shown in fig. 4, the upper metal plate 61 is provided with an upper arc-shaped contact piece 613 on the side facing the lower metal plate 62, the lower metal plate 62 is provided with a lower arc-shaped contact piece 623 corresponding to the upper arc-shaped contact piece 613, and the upper arc-shaped contact piece 613 and the lower arc-shaped contact piece 623 cooperate to form the contact gap 63.
In this embodiment, the upper arc-shaped contact piece 613 and the lower arc-shaped contact piece 623 are arranged, so that the triggering of the alarm 72 is no longer limited to when the end surface of the upper metal plate 61 is attached to the end surface of the lower metal plate 62, but when the vertex of the upper arc-shaped contact piece 613 is contacted with the vertex of the lower arc-shaped contact piece 623, or when any part of the upper arc-shaped contact piece 613 is contacted with any part of the lower arc-shaped contact piece 623, thereby improving the triggering sensitivity of the alarm 72, that is, the early warning sensitivity of the blocking of the urban water conservancy pipeline 2.
Further, referring to fig. 2 and fig. 1, a hook 34 is disposed on an outer side wall of the float 3, an installation component 11 corresponding to the hook 34 is disposed on an inner side wall of the inspection well 1, and a hook groove 111 matched with the hook 34 is formed at one end of the installation component 11 away from the inner side wall of the inspection well 1; when the buoy 3 is connected to the inspection well 1, the hook 34 is accommodated and limited in the hook groove 111.
In this embodiment, the buoy 3 is detachably connected to the mounting member 11 through the engagement of the hook 34 and the hook slot 111, and the mounting member 11 is fixedly disposed on the inner side wall of the inspection well 1, so as to detachably connect the buoy 3 to the inner side wall of the inspection well 1. The design that the buoy 3 can be dismantled with the inside wall of inspection shaft 1 and be connected has made things convenient for the dismantlement of buoy 3 from inspection shaft 1 and the change of buoy 3.
Further, as shown in fig. 1, the pontoon 3 is provided with a filter screen 321 at the water inlet 32.
In this embodiment, often have debris and rubbish in the urban water conservancy pipeline 2, if debris and rubbish get into the cavity 31 of flotation pontoon 3 through water inlet 32 in, then can lead to floating seat 4, the damage of ejector pin 5, and probably lead to the false triggering of alarm 72, the event sets up the filter screen 321 that can carry out the filtration to debris and rubbish in water inlet 32 department, so that most debris and rubbish can't all get into the cavity 31 of flotation pontoon 3 through filter screen 321 and water inlet 32, avoid floating seat 4, the damage of ejector pin 5 and the false triggering of alarm 72.
Further, as shown in fig. 1, the float seat 4 is an air bag having a vacuumed bag chamber (not shown).
