[0018] Beneficial effects of the utility model:

[0019] When measuring the flow rate of the filter tank, the water level reaches the first liquid level sensor, and the controller sends a signal to start timing.

DETAILED DESCRIPTION

[0031] The following is a combination of the appended examples of the present invention Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0032] Example 1, a V-type filter tank filtration rate measuring device, comprising a measuring rod 1 and a fixing bracket 2, characterized in that: the top of the measuring rod 1 is connected to a display screen 3, the display screen 3 is used to display the measurement time and the calculated rate, and the bottom is connected to a protective cover 4, the protective cover 4 is slidably provided with a first liquid level sensor 5 and a second liquid level sensor 6, and the protective cover 4 is provided with an adjustment component for adjusting the distance between the first liquid level sensor 5 and the second liquid level sensor 6;

[0033] The fixing bracket 2 is provided with a clamping plate 7 that cooperates with the measuring rod 1. The clamping plate 7 is threadedly connected with a locking screw 8. The locking screw 8 facilitates adjustment of the locking position of the clamping plate 7 and the measuring rod 1, which is easy to adjust and simple to operate.

[0034] A controller 9 is provided in the measuring rod 1 , and a power signal control line 10 is connected between the first liquid level sensor 5 , the second liquid level sensor 6 , and the display screen 3 and the controller 9 .

[0035] When this embodiment is in use, in the process of measuring the flow rate of the filter tank, when the water level reaches the first liquid level sensor 5, the controller 9 sends a signal to start timing. When the water level reaches the second liquid level sensor 6, the controller 9 sends a signal to stop timing. The time from the first liquid level sensor 5 to the second liquid level sensor 6 is recorded. The display screen 3 cooperates with the controller 9 to display the time and the calculation rate. For deep water levels, the required measurement distance becomes longer, and for shallow water levels, the required measurement distance becomes shorter.

[0036] The regulating component is driven and regulated according to the water level of the filter tank, thereby changing the distance between the first liquid level sensor 5 and the second liquid level sensor 6, increasing or decreasing the distance between the first liquid level sensor 5 and the second liquid level sensor 6;

[0037] After the adjustment is completed, the measuring rod 1 is matched with the clamping plate 7 provided at the front end of the fixing bracket 2. Two sets of locking screws 8 are provided symmetrically on the center of the clamping plate 7. The two sets of locking screws 8 are rotated to lock the measuring rod 1 on the fixing bracket 2. The fixing bracket 2 is fixed to the filter tank frame, so that the measuring rod 1 is deeply inserted into the filter tank and the display screen 3 is above the water level, which is convenient for the operator to observe the measurement data.

[0038] The cooperation between the first liquid level sensor 5 and the second liquid level sensor 6 and the controller 9 solves the technical problem of deviation in measuring the filtration rate of the filter tank using a traditional stopwatch and a measuring ruler, which leads to inaccurate filtration rate measurement and inability to obtain correct measurement data; by adjusting the components, the scope of use of this equipment is improved.

[0039] As a further embodiment, the adjustment assembly includes a bidirectional screw 11 rotatably connected inside the protective cover 4, two sets of sliding grooves 12 are provided on the protective cover 4, and the first liquid level sensor 5 and the second liquid level sensor 6 are respectively fixedly connected with a first connecting plate 13 and a second connecting plate 14 that match the sliding grooves 12, the first connecting plate 13 and the second connecting plate 14 are threadedly connected to the bidirectional screw 11, and an adjustment handle 15 is provided at one end of the bidirectional screw 11.

[0040] As a further embodiment, the two groups of sliding grooves 12 are symmetrically arranged about the center of the protective cover 4, and one group of sliding grooves 12 is arranged at the top of the protective cover 4, and the other group of sliding grooves 12 is arranged at the bottom of the protective cover 4. In this design, the first liquid level sensor 5 and the second liquid level sensor 6 are located at both ends of the measuring rod 1, further improving the detection accuracy.

[0041] As a further embodiment, a positioning plate 22 is provided on the inner wall of the measuring rod 1, and a through hole 23 is provided on the positioning plate 22 for cooperating with the power signal control line 10. The diameter of the through hole 23 is larger than the diameter of the power signal control line 10, so that the power signal control line 10 can only move vertically along the through hole 23 provided on the positioning plate 22.

[0042] As a further embodiment, the fixing bracket 2 is made of stainless steel.

[0043] When in use, the distance between the first liquid level sensor 5 and the second liquid level sensor 6 is adjusted according to the different water levels in the filter tank;

[0044] By rotating the adjustment handle 15, the bidirectional screw is driven to rotate. Since the threads at both ends of the bidirectional screw are opposite to each other, the first connecting plate 13 and the second connecting plate 14 fixedly connected to the rear ends of the first liquid level sensor 5 and the second liquid level sensor 6 are respectively threadedly connected to the opposite threaded ends of the bidirectional screw. The first connecting plate 13 and the second connecting plate 14 are slidably connected to the sliding groove 12. The two groups of sliding grooves 12 are symmetrically arranged about the center of the protective cover 4, and one group of sliding grooves 12 is arranged at the top of the protective cover 4, and the other group of sliding grooves 12 is arranged at the bottom of the protective cover 4. Therefore, the rotation of the bidirectional screw 11 can drive the first connecting plate 13 and the second connecting plate 14 to move relative to each other along the sliding groove 12, thereby adjusting the distance between the first liquid level sensor 5 and the second liquid level sensor 6, so as to be suitable for filter tanks with different water levels;

[0045] A power signal control line 10 is connected between the first liquid level sensor 5, the second liquid level sensor 6 and the controller 9. A margin is set for the power signal control line 10 here so that there will be no interference when the positions of the first liquid level sensor 5 and the second liquid level sensor 6 are changed. The positioning plate 22 is provided with a through hole 23, and the power signal control line 10 passes through the through hole 23. The diameter of the through hole 23 is larger than the diameter of the power signal control line 10. Therefore, the power signal control line 10 can slide along the through hole 23, and the power signal control line 10 can only slide vertically, thereby avoiding the entanglement of the power signal control lines 10 of the first liquid level sensor 5 and the second liquid level sensor 6 when they move.

[0046] Example 2, a scum interception device for wet water intake deep wells in a waterworks. Based on Example 1, as an optional implementation, a long groove 16 is provided on the fixed bracket 2, and a positioning screw 17 is provided in the long groove 16. The positioning screw 17 is equipped with two sets of positioning nuts 18, and the two sets of positioning nuts 18 are respectively located at both ends of the fixed bracket 2. The positioning screw 17 passes through the filter tank frame and is locked and fixed by the two sets of nuts 18.

[0047] As a further embodiment, one end of the clamping plate 7 is opened, and a non-slip pad is provided at the contact portion between the inner side wall of the clamping plate 7 and the outer side wall of the measuring rod 1 .

[0048] When in use, through the cooperation of the long slot 16, the positioning screw 17 and the two sets of positioning nuts 18, it is possible to achieve convenient adjustment when the fixing bracket 2 is fixed to the filter frame, and change the distance between the measuring rod 1 and the filter frame;

[0049] An anti-slip pad is provided at the contact portion between the inner side wall of the clamping plate 7 and the outer side wall of the measuring rod 1 , thereby further strengthening the locking force between the clamping plate and the measuring rod 1 .

[0050] Example 3, a scum interception device for a deep well wet water intake in a waterworks, based on Example 1 or 2, wherein the protective cover 4 is made of a transparent material.

[0051] As a further embodiment, the protective cover 4 is provided with a plurality of drainage holes 19 .

[0052] Example 4, a scum interception device for wet water intake deep wells in a waterworks. Based on Example 1 or 2, the measuring rod 1 includes a top and a bottom. The top of the measuring rod 1 and the bottom of the measuring rod 1 are connected via a foldable joint. The top of the measuring rod 1 is provided with an armature 20, and the bottom of the measuring rod 1 is provided with a magnetic plate 21 that cooperates with the armature 20.

[0053] In this embodiment, the measuring rod 1 is configured as a top portion of the measuring rod 1 and a bottom portion of the measuring rod 1, which are connected by a foldable joint. When not in use, the clamping plate 7 is removed by the locking screw 8, and the top portion of the measuring rod 1 and the bottom portion of the measuring rod 1 are folded together. After folding, the top portion of the measuring rod 1 and the bottom portion of the measuring rod 1 are folded into one piece by cooperating with the magnetic plate 21 and the armature 20, which is convenient for carrying. By cooperating with the armature 20 and the magnetic plate 21, the measuring rod 1 will not rock back and forth during transportation, thereby avoiding damage to the measuring rod 1 body.
