Description

Technical Field

[0001] The utility model relates to the field of tailing ponds, in particular to a device for on-site measuring the wastewater flow rate at the outlet of a culvert in a tailing pond. Background Art

[0002] A tailing pond refers to a place formed by building a dam to intercept the valley mouth or enclosing land for storing tailings or other industrial waste residues discharged after ore separation in a metal or non-metal mine. Wastewater is generated when the tailing pond is in use. The wastewater is generally drained through the culvert of the tailing pond. The wastewater converges in the culvert of the tailing pond and then drains out from the outlet of the culvert of the mine.

[0003] When discharging wastewater at the outlet, it is necessary to measure the wastewater flow rate, so as to measure the total amount of wastewater discharged and facilitate the control of pollution. The prior art generally connects a flow velocity sensing device to the outlet. However, some culverts use drainage channels for drainage instead of pipe-type outlets. The flow velocity sensing device needs to be placed in the drainage channel to allow the wastewater to pass through the flow velocity sensing device, thereby measuring the flow velocity of the wastewater. The wastewater flow rate is calculated through the flow velocity and the liquid level in the drainage channel. However, when in use, it is difficult to fix the flow velocity sensing device in the drainage channel, so it is difficult to detect the wastewater flow rate in the drainage channel.

The outer surface of the tightening bolt 802 is in contact with the outer surface of the sliding rod 2. The upper end of the sliding rod 2 is fixedly connected with a horizontally extending handle 7.

[0031] A connecting frame 4 is provided at the lower end of the telescopic member. A flow velocity sensing device 5 is detachably connected in the connecting frame 4. The connecting frame 4 includes an upper connecting frame 401. The lower end of the upper connecting frame 401 is detachably connected to a lower connecting frame 402 by bolts. A jack is provided on the upper connecting frame 401, and a bolt is inserted in the jack. The lower end of the bolt is threadedly connected to a threaded connection hole on the lower connecting frame 402. The upper connecting frame 401 is a semi-circular structure with a lower opening, and the lower connecting frame 402 is a semi-circular structure with an upper opening. The upper connecting frame 401 and the lower connecting frame 402 form a circular structure which holds the flow velocity sensing device 5 by hoop. The flow velocity sensing device 5 can be selected as a differential pressure type flow velocity sensor in this embodiment. The wastewater passes through the venturi tube on the differential pressure type flow velocity sensor, and a pressure difference is generated when the fluid passes through the throttling element, and the fluid flow velocity is obtained through the pressure difference.

[0032] A telescopic rod 6 extending in the left-right direction is provided on the support plate 1. The telescopic rod 6 includes a connecting rod 601 which extends in the left-right direction. Screw rods 602 are fixedly connected to both the left and right ends of the connecting rod 601. A sleeve 604 is provided on the screw rod 602, and a threaded structure is provided in the sleeve 604. The sleeve 604 is threadedly sleeved on the screw rod 602 through the threaded structure; Two sliding limit frames 603 are fixedly connected to the support plate 1, and the two sliding limit frames 603 are corresponding in the left-right position; A horizontally penetrating chute is provided on the sliding limit frame 603, and the sleeve 604 is slidably arranged in the chute on the sliding limit frame 603 on the same side, and a limiting structure for limiting the rotation of the sleeve 604 is provided in the chute.

[0033] The limiting structure includes a limiting groove. A protrusion extending in the left-right direction is provided on the sleeve 604. The limiting groove extends in the left-right direction and is provided in the chute. The protrusion on the sleeve 604 is slidably arranged in the limiting groove.

[0034] Both the opposite ends of the two sleeves 604 are fixedly connected with top plates 9, and rubber friction pads 10 are fixedly connected to the top plates 9. The rubber friction pads 10 can be selected as rubber materials in this embodiment.

[0035] Working principle: During the working process, the staff first measures the wastewater liquid level through the water level scale line in the drainage channel or a portable liquid level gauge.

[0036] Then place this device in the drainage channel, and then rotate the connecting rod 601. The rotation of the connecting rod 601 drives the rotation of the screw rod 602. The rotation of the screw rod 602 drives the sleeves 604 to move away from each other under the limiting action of the sliding limiting frame 603 until the sleeves 604 press the top plate 9 against the inner wall of the drainage channel, so that this device is locked in the drainage channel.

[0037] Then rotate the tightening bolt 802. The tightening bolt 802 moves to the right, so that the tightening bolt 802 disengages from the contact with the sliding rod 2. Then pull the handle 7 downward. The downward movement of the sliding rod 2 drives the connecting frame 4 to move upward. The connecting frame 4 drives the flow velocity sensing device 5 downward, so that the flow velocity sensing device 5 is immersed in the wastewater in the drainage channel, and the wastewater flows into the flow velocity sensing device 5, thereby measuring the flow velocity of the wastewater.

[0038] The size of the drainage channel is fixed. The cross-sectional area of the liquid can be obtained through the water level, and the wastewater flow rate can be obtained by multiplying the cross-sectional area of the liquid by the wastewater flow velocity.

[0039] After the measurement is completed, rotate the connecting rod 601 in the reverse direction. The rotation of the connecting rod 601 drives the rotation of the screw rod 602. The rotation of the screw rod 602 drives the sleeves 604 to approach each other under the limiting action of the sliding limiting frame 603, thereby releasing the locking of the device in the drainage channel.

[0040] Thus, the flowmeter can be fixed in the drainage channel during use, and then the flow velocity sensing device 5 can be placed into the wastewater by adjusting the up and down positions, so that the flow velocity of the wastewater can be quickly measured. At the same time, after the use is completed, the device can be quickly recovered, so that the wastewater flow rate in the drainage channel can be detected.

[0041] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
