Description

A device for diverting river water to flush sediments in storage tanks

technical field

The utility model relates to the technical field of municipal engineering, in particular to a device for guiding river water to wash sediments in storage tanks.

Background technique

The initial rainwater runoff carried pollutants on the ground and sediments in the pipes and other impurities. After the initial rain entered the storage tank, sediments inevitably remained at the bottom. If it is not cleaned in time, it will cause sediment compaction, deterioration, and odor. Excessive accumulation of sediment will reduce the effective volume of the storage tank and fail to perform its effective functions.

Therefore, the rainwater storage tank must have equipment and devices that can effectively flush the bottom sediment. Traditional storage tank flushing technologies mainly include: hydraulic flushing tipping bucket, water ejector flushing, portal flushing and vacuum flushing and other technologies. Traditional flushing technology generally has disadvantages such as high investment, inability to flush multiple times, incomplete flushing effect, and high energy consumption. Therefore need a kind of novel device to solve the above problems.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a device for guiding river water to flush sediments in storage tanks, so as to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

A device for diverting river water to flush sediments in a storage tank, including a storage tank installed underground by the river, characterized in that a butterfly valve well is provided on one side of the storage tank, and the butterfly valve well is away from the side of the storage tank There is a first water inlet pipe with one end running through the side wall of the butterfly valve well and the other end connected to the river channel. Water pipe, the butterfly valve well is provided with telescopic joints with two ends respectively connected to the first water inlet pipe and the second water inlet pipe, the top of the telescopic joint is provided with a quick-opening electric butterfly valve, and the storage tank is away from the side of the butterfly valve well A sump is provided at the bottom of the pool, and a flushing corridor is provided between the sump and the second water inlet pipe.

In the above technical solution, the device for diverting river water to flush the sediment in the storage tank is characterized in that: one end of the second water inlet pipe located in the storage tank is provided with a flushing horizontal pipe, and the flushing horizontal pipe is another A plurality of flushing nozzles are arranged on one side wall.

In the above technical solution, the device for diverting river water to flush sediments in storage tanks is characterized in that: multiple sewage pumps are arranged in the sump, and each sewage pump is provided with one end connected to the sewage discharge pump. The pump is connected, and the other end runs through the side wall of the storage tank and extends to the sewage pipe outside the storage tank.

The beneficial effects of the utility model are as follows: 1. Good flushing effect: Compared with the traditional flushing technology of storage tanks, this technology is constant flow and fixed water level flushing, with high flushing flow rate, unlimited repeated flushing, and better flushing effect; 2. Energy-saving and economical: make full use of the difference between the water level of the river and the flushing water level of the storage tank, and rely on the potential energy of gravity to flush the storage tank. The flushing control facilities are only quick-opening flushing valves (power much lower than traditional flushing) and matching flushing pipes, with low energy consumption. Low investment; 3. Safe and easy maintenance and management: Since there is only one kind of equipment, the electric quick-opening butterfly valve, and it is built separately from the storage tank, there is no need to lower the maintenance of the storage tank, and the operation is safe and easy.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

A device for leading river water to flush deposits in storage tanks as shown in Figures 1 and 2, comprising a storage tank 2 arranged underground by the river, top of the storage tank 2 having a top cover soil 1, said storage tank 2- A butterfly valve well 4 is provided on the side, and the side of the butterfly valve well 4 facing away from the storage tank 2 is provided with a first water inlet pipe 6 with one end running through the side wall of the butterfly valve well 4 and the other end connected to the river channel 3. The storage tank 2 and Between the butterfly valve wells 4 there is provided a second water inlet pipe 14 whose two ends respectively pass through the side walls of the storage tank 2 and the side walls of the butterfly valve wells 4 . One end of the second water inlet pipe 14 located in the storage tank 2 is provided with a flushing horizontal pipe 8 , and four flushing nozzles 9 are provided on the side wall of the other side of the flushing horizontal pipe 8 .

The butterfly valve well 4 is provided with a telescopic joint 7 with two ends connected to the first water inlet pipe 6 and the second water inlet pipe 14 respectively. The top of the telescopic joint 7 is provided with a quick-opening electric butterfly valve 5, and the storage tank 2 deviates from the A sump 11 is provided at the bottom of the pool on one side of the butterfly valve well 4 , and a flushing corridor 10 is provided between the sump 11 and the second water inlet pipe 14 .

The sump 11 is provided with two sewage pumps 12, and each of the sewage pumps 12 is provided with one end connected to the sewage pump 12, and the other end passing through the side wall of the storage tank 2 and extending to the outside of the storage tank 2. Sewage pipe 13.

When the device is in use, an underground storage tank is installed on the riverside. The river channel 3 next to the storage tank 2 has sufficient water volume; 9 water flow rate requirements.

At the front end of storage tank 2, there needs to be a space to install butterfly valve well 4. The opening and closing time of electric quick-opening butterfly valve 5 is ≤15s. Due to the difference between the water level of the river channel and the flushing water level of the storage tank, the gravitational potential energy of the river water body is converted into kinetic energy of water. The channel water is introduced into the flushing corridor sediments through rapid opening and closing.
