Technical Field

[0001] The utility model relates to the technical field of reservoir flow monitoring, in particular to a flow monitoring device used in a reservoir. Background Art

[0002] For reservoirs with channel outlets, since most channels are irregular in shape, it is necessary to artificially build water measuring weirs and install automatic water level monitoring sensors and conventional flow velocity measuring devices at the cross-section. The water level is converted into the cross-section water flow area, and the flow value is obtained by integrating the water flow area and the flow velocity. The characteristics of channel downstream flow detection are that the installation and construction are less difficult and have a wide range of applications.

[0003] A flow monitoring device for use in a reservoir is disclosed in a Chinese utility model patent with publication number CN215177922U, which specifically relates to the field of reservoir flow monitoring, including a reservoir channel, wherein fixed frames are fixedly installed on both sides of the reservoir channel, a mounting seat is movably provided on one side of the fixed frame, and two groups of mounting seats are arranged corresponding to the fixed frame, a fixed shaft is fixedly connected between the two groups of mounting seats, a mounting box is movably provided at the bottom of the fixed shaft, a ball screw is fixedly installed on the top of one group of mounting seats, and a wire reel is fixedly installed on the top of the other group of mounting seats, a connecting block is fixedly connected to the top of the installing box, and the top of the connecting block is movably connected to the fixed block; a fixing port and a slide groove are provided inside the fixing frame, the slide groove is connected to the fixed port, and the diameter of the slide groove is larger than the diameter of the fixing port.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the water outlet is blocked during detection in the above-mentioned device, the water flow inside the water outlet cannot flow through the water outlet, thereby causing the flow velocity in the water outlet to decrease, and then causing the water level in the water outlet to gradually increase, thereby causing deviations in the measured data. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a flow monitoring device used in a reservoir.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a flow monitoring device used in a reservoir, comprising an outlet pipe, a connecting piece is fixedly provided at one end of the outlet pipe, a drain pipe is fixedly provided at the end of the connecting piece away from the outlet pipe, a through hole is penetrated through the side wall of the connecting piece, the outlet pipe, the through hole and the drain pipe are connected to each other, an automatic water level monitoring sensor is fixedly provided on the inner wall of the drain pipe, a conventional flow velocity measuring device is fixedly provided on the inner wall of the drain pipe, and a blocking device is installed in the through hole.

[0007] By adopting the above technical scheme, when the staff needs to monitor the outflow of the reservoir, the staff needs to start the automatic water level monitoring sensor and the conventional flow velocity measuring device to monitor the water flow in the drain pipe. During this process, the water in the reservoir passes through the outlet pipe, the through hole and the drain pipe in turn, so that the automatic water flow monitoring sensor and the conventional flow velocity measuring device monitor the water flow out of the drain pipe. During this process, when the drain pipe is blocked, the blocking device is started, and the blocking device blocks the water flow, thereby reducing the probability of water flowing into the drain pipe, thereby reducing the probability of the water level in the drain pipe rising, thereby reducing the probability of deviation in the measurement data.

[0008] Furthermore, a rotating groove is symmetrically opened on the inner wall of the through hole, and the blocking device includes a rotating rod rotatably arranged in the rotating groove, a rotating plate rotatably arranged in the through hole, and a fixed plate fixedly arranged in the through hole, the rotating plate and the rotating rod are fixed to each other, and the side wall of the rotating plate away from the drain pipe abuts against the side wall of the fixed plate close to the drain pipe.

[0009] By adopting the above technical solution, when the water in the reservoir passes through the outlet pipe, the through hole and the drain pipe in sequence, the rotating plate rotates under the action of the water flow, thereby causing the water to flow into the drain pipe. During this process, when the drain pipe is blocked, the water cannot continue to flow, and the staff needs to rotate the rotating plate to block the water flow, thereby reducing the probability of water flowing into the drain pipe, thereby reducing the probability of the water level in the drain pipe rising, thereby reducing the probability of deviation in the measurement data.

[0010] Furthermore, a reset groove is provided on the inner wall of the rotation groove, a torsion spring is fixedly provided on the inner wall of the reset groove, and the other end of the torsion spring is fixedly provided on the side wall of the rotation rod.

[0011] By adopting the above technical solution, the torsion spring reduces the difficulty for the staff to rotate the rotating plate, thereby reducing the working difficulty of the staff.

[0012] Furthermore, a slide groove is provided on the inner wall of the reset groove, a slider is slidably provided in the slide groove, a control switch is fixedly provided on the inner wall of the slide groove, and the control switch is electrically connected to the automatic water level monitoring sensor and the conventional flow rate measuring device.

[0013] By adopting the above technical scheme, when the rotating plate rotates under the action of water flow, the staff needs to start the control switch, thereby starting the automatic water level monitoring sensor and the conventional flow rate measuring device, so that the automatic water level monitoring sensor and the conventional flow rate measuring device can monitor the water flow, thereby reducing the difficulty for the staff to start the automatic water level monitoring sensor and the conventional flow rate measuring device, thereby reducing the difficulty of the staff's work.

[0014] Furthermore, a threaded rod is fixedly provided on the side wall of the rotating rod close to the slider, and the threaded rod is threadably connected to the slider.

[0015] By adopting the above technical solution, when the rotating plate rotates under the action of water flow, the rotating rod rotates with the rotating plate, and then the threaded rod rotates with the rotating rod, so that the slider slides in the direction close to the control switch under the action of the threaded rod, and then the control switch is triggered, so that the water level automatic monitoring sensor and the conventional flow rate measuring device are started. Subsequently, when the rotating plate is reset under the action of the torsion spring, the rotating rod resets with the rotating plate, and then the threaded rod resets with the rotating rod, so that the slider slides in the direction away from the control switch under the action of the threaded rod, and then the slider and the control switch are separated from each other, so that the water level automatic monitoring sensor and the conventional flow rate measuring device are turned off, thereby reducing the probability of continuing measurement when blocked, thereby improving the accuracy of the measurement data.

[0016] Furthermore, one end of the rotating plate close to the fixed plate is provided with a rounded corner.

[0017] By adopting the above technical solution, the rounded corners reduce the probability of the rotating plate colliding with the fixed plate when rotating, thereby improving the stability of the device.

[0018] Furthermore, a first spring is fixedly arranged on the side wall of the sliding block, and the other end of the first spring is fixedly arranged on the inner wall of the sliding groove.

[0019] By adopting the above technical solution, the first spring supports the slider, thereby reducing the probability of damage to the control switch, thereby extending the service life of the device.

[0020] In summary, the utility model has the following beneficial effects:

During this process, the water in the reservoir passes through the outlet pipe, the through hole and the drain pipe in turn, so that the automatic water flow monitoring sensor and the conventional flow velocity measuring device monitor the water flow out of the drain pipe. During this process, when the drain pipe is blocked, the blocking device is started, and the blocking device blocks the water flow, thereby reducing the probability of water flowing into the drain pipe, thereby reducing the probability of the water level in the drain pipe rising, thereby reducing the probability of deviation in the measurement data;

[0022] 2. In the present application, when the water in the reservoir passes through the outlet pipe, the through hole and the drain pipe in sequence, the rotating plate rotates under the action of the water flow, thereby causing the water flow to flow into the drain pipe.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-4As shown, the embodiment of the present application discloses a flow monitoring device for use in a reservoir, including an outlet pipe 1, a connector 11, a drain pipe 12, an automatic water level monitoring sensor 13, a conventional flow velocity measuring device 14, a blocking device 3, a slider 5, a control switch 51, and a threaded rod 6. The outlet pipe 1 is a circular tubular structure, and its axis is horizontal. The connector 11 is fixedly arranged at one end of the outlet pipe 1, and a through hole 2 is penetrated through the side wall of the connector 11. The drain pipe 12 is a circular tubular structure, and its axis coincides with the axis of the outlet pipe 1. The drain pipe 12 is fixedly arranged at one end of the connector 11 away from the outlet pipe 1, and the outlet pipe 1, the through hole 2, and the drain pipe 12 are connected to each other. The automatic water level monitoring sensor 13 is fixedly arranged on the inner wall of the drain pipe 12, and the conventional flow velocity measuring device 14 is fixedly arranged on the inner wall of the drain pipe 12.

[0031] When the staff needs to monitor the outflow of the reservoir, the staff needs to start the automatic water level monitoring sensor 13 and the conventional flow rate measuring device 14 to monitor the water flow of the drain pipe 12. During this process, the water in the reservoir passes through the outlet pipe 1, the through hole 2 and the drain pipe 12 in turn, so that the automatic water flow monitoring sensor and the conventional flow rate measuring device 14 monitor the water flow out of the drain pipe 12. During this process, when the drain pipe 12 is blocked, the blocking device 3 is started, and the blocking device 3 blocks the water flow, thereby reducing the probability of water flowing into the drain pipe 12, thereby reducing the probability of the water level in the drain pipe 12 rising, thereby reducing the probability of deviation in the measurement data.

[0032] A rotation groove 21 is symmetrically provided on the inner wall of the through hole 2, and the blocking device 3 is installed in the through hole 2. The blocking device 3 includes a rotation rod 31, a rotation plate 32 and a fixed plate 33. The rotation rod 31 is a round rod-shaped structure with a horizontal axis. The rotation rod 31 is rotatably arranged in the rotation groove 21. The cross section of the rotation plate 32 is in the shape of an arc. The rotation plate 32 is rotatably arranged in the through hole 2, and the rotation plate 32 and the rotation rod 31 are fixed to each other. The cross section of the fixed plate 33 is in the shape of an arc. The fixed plate 33 is fixedly arranged in the through hole 2, and the side wall of the rotation plate 32 away from the drain pipe 12 abuts against the side wall of the fixed plate 33 close to the drain pipe 12.

[0033] When the water in the reservoir passes through the outlet pipe 1, the through hole 2 and the drain pipe 12 in sequence, the rotating plate 32 rotates under the action of the water flow, thereby causing the water to flow into the drain pipe 12. During this process, when the drain pipe 12 is blocked, the water cannot continue to flow, and the staff needs to rotate the rotating plate 32 to block the water flow, thereby reducing the probability of the water flowing into the drain pipe 12, thereby reducing the probability of the water level in the drain pipe 12 rising, thereby reducing the probability of deviation in the measurement data.

[0034] In order to reduce the difficulty of the staff's work, a reset groove 22 is opened on the inner wall of the rotating groove 21, and a torsion spring 4 is fixedly arranged on the inner wall of the reset groove 22, and the other end of the torsion spring 4 is fixedly arranged on the side wall of the rotating rod 31. The torsion spring 4 reduces the difficulty of the staff to rotate the rotating plate 32, thereby reducing the difficulty of the staff's work.

[0035] A chute 23 is provided on the inner wall of the reset groove 22. The slider 5 is a rectangular block structure and is slidably arranged in the chute 23. A control switch 51 is fixedly arranged on the inner wall of the chute 23 and is electrically connected to the automatic water level monitoring sensor 13 and the conventional flow velocity measuring device 14.

[0036] When the rotating plate 32 rotates under the action of water flow, the staff needs to start the control switch 51, thereby starting the automatic water level monitoring sensor 13 and the conventional flow rate measuring device 14, so that the automatic water level monitoring sensor 13 and the conventional flow rate measuring device 14 monitor the water flow, thereby reducing the difficulty of the staff to start the automatic water level monitoring sensor 13 and the conventional flow rate measuring device 14, thereby reducing the difficulty of the staff's work.

[0037] The threaded rod 6 is fixedly disposed on the side wall of the rotating rod 31 close to the sliding block 5 , and the axis of the threaded rod 6 coincides with the axis of the rotating rod 31 . The threaded rod 6 is threadedly connected to the sliding block 5 .

[0038] When the rotating plate 32 rotates under the action of the water flow, the rotating rod 31 rotates following the rotating plate 32, and then the threaded rod 6 rotates following the rotating rod 31, so that the slider 5 slides in the direction close to the control switch 51 under the action of the threaded rod 6, and then the control switch 51 is triggered, so that the automatic water level monitoring sensor 13 and the conventional flow rate measuring device 14 are started. Subsequently, when the rotating plate 32 is reset under the action of the torsion spring 4, the rotating rod 31 is reset following the rotating plate 32, and then the threaded rod 6 is reset following the rotating rod 31, so that the slider 5 slides in the direction away from the control switch 51 under the action of the threaded rod 6, and then the slider 5 and the control switch 51 are separated from each other, so that the automatic water level monitoring sensor 13 and the conventional flow rate measuring device 14 are turned off, thereby reducing the probability of continuing measurement when blocked, thereby improving the accuracy of the measurement data.

[0039] In order to improve the stability of the device, a rounded corner 7 is provided at one end of the rotating plate 32 close to the fixed plate 33. The rounded corner 7 reduces the probability of the rotating plate 32 colliding with the fixed plate 33 when rotating, thereby improving the stability of the device.

[0040] In order to extend the service life of the device, a first spring 8 is fixedly arranged on the side wall of the slider 5, and the other end of the first spring 8 is fixedly arranged on the inner wall of the slide groove 23. The first spring 8 supports the slider 5, thereby reducing the probability of damage to the control switch 51, thereby extending the service life of the device.

[0041] The use principle of a flow monitoring device used in a reservoir in the present embodiment is as follows: when the staff needs to monitor the outflow of the reservoir, the staff needs to start the automatic water level monitoring sensor 13 and the conventional flow velocity measuring device 14 to monitor the water flow of the drain pipe 12. During this process, the water in the reservoir passes through the outlet pipe 1, the through hole 2 and the drain pipe 12 in turn, so that the automatic water flow monitoring sensor and the conventional flow velocity measuring device 14 monitor the water flow out of the drain pipe 12. During this process, when the drain pipe 12 is blocked, the water flow cannot continue to flow, and the staff needs to rotate the rotating plate 32, so that the rotating plate 32 blocks the water flow, thereby reducing the probability of water flowing into the drain pipe 12, thereby reducing the probability of the water level in the drain pipe 12 rising, thereby reducing the probability of deviation in the measurement data.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
