Description

Technical Field

[0001] The present application relates to the field of municipal administration, and in particular to a sponge city rainwater treatment device. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept that aims to make cities like sponges, with good "elasticity" in adapting to environmental changes and responding to natural disasters.

[0003] Referring to the Chinese utility model patent number CN213313722U, a sponge city rainwater filter is disclosed, including a shell having an inlet pipe and an outlet pipe, and a filter body floatingly arranged in the shell between the inlet pipe and the outlet pipe, and an impurity cavity is formed between the side wall of the filter body and the side wall of the shell, and the inlet pipe is located above the filter body and is offset to one side of the filter body. The sponge city rainwater filter described in the utility model increases the contact area between the filter body and the rainwater by setting the filter body and forming an impurity cavity between the filter body and the shell, and makes impurities fall into the impurity cavity. When the impurity cavity stores a large amount of impurities, the filter body can still have a good filtering effect.

[0004] In actual use, impurities in the impurity chamber are inconvenient to clean, which needs to be improved. Summary of the invention

[0005] In order to facilitate the cleaning of impurities after rainwater filtration in sponge cities, the present application provides a sponge city rainwater treatment device.

[0006] The present application provides a sponge city rainwater treatment device, which adopts the following technical solution:

[0007] A sponge city rainwater treatment device comprises a tank body, the tank body is provided with a water storage cavity, the tank body is provided with a liquid inlet and a liquid outlet, the liquid inlet and the liquid outlet are both connected to the water storage cavity, the water storage cavity wall is provided with a floating plate, the floating plate is rotatably connected to the water storage cavity wall, the water storage cavity wall is provided with a receiving groove, the receiving groove is located at the side of the connection between the floating plate and the water storage cavity wall away from the bottom of the water storage cavity, the rotation direction of the floating plate is the direction close to the bottom of the receiving groove, the receiving groove is provided with a limit piece, the limit piece is used to close the receiving groove; when the liquid level of the water storage cavity is lower than the position of the receiving groove, the limit piece closes the receiving groove, and when the liquid level of the water storage cavity is higher than the receiving groove, the receiving groove is connected to the water storage cavity.

[0008] By adopting the above technical solution, a storage tank is provided, and floating impurities in the water storage chamber are stored through the storage tank. When it is necessary to remove the floating impurities, it is only necessary to make the liquid level in the water storage chamber lower than the height of the storage tank, and then remove the floating impurities in the storage tank. Through such a setting, it is convenient to centrally process floating objects and other impurities, making the overall impurity removal more convenient. Secondly, when the liquid level drops, the storage tank is closed by the closing member, which reduces the situation where impurities in the storage tank return to the water storage chamber.

[0009] Optionally, a limiting groove is provided at the mouth of the storage groove, and the limiting groove is located on the side of the storage groove away from the bottom of the water storage chamber. The limiting member includes a limiting plate and a limiting spring, and the limiting spring is located at the bottom of the limiting groove. The density of the limiting plate is less than the density of the liquid. The limiting plate is provided with a filter hole, and the filter hole passes through the limiting plate. A water-permeable membrane is provided at one end of the limiting plate close to the bottom of the storage groove, and the elastic force of the limiting spring limits the limiting plate from moving in a direction away from the bottom of the limiting groove.

[0010] By adopting the above technical solution, a limit plate and a limit spring are set, and the elastic force of the limit spring limits the limit plate to move in the direction away from the bottom of the limit groove, so as to facilitate the rapid floating of the limit plate. When the liquid level drops, the limit plate drops together and gradually closes the receiving groove. The liquid in the receiving groove passes through the water-permeable membrane, and floating debris remains in the receiving groove, which is convenient for subsequent cleaning.

[0011] Optionally, the limit plate is provided with a limit magnetic strip 1, and the limit magnetic strip 1 is located at one end of the limit plate close to the bottom of the limit groove. The limit magnetic strip 1 connects the limit plate and the limit spring, and a limit magnetic strip 2 is provided at the bottom of the limit groove. The magnetic force of the limit magnetic strip 2 and the magnetic force of the limit magnetic strip 1 attract each other.

[0012] By adopting the above technical solution, limit magnetic strip 1 and limit magnetic strip 2 are set, and the magnetic forces of limit magnetic strip 1 and limit magnetic strip 2 attract each other. When the limit plate floats and compresses the limit spring, the distance between limit magnetic strip 1 and limit magnetic strip 2 is reduced, so the attraction between limit magnetic strip 1 and limit magnetic strip 2 is increased, thereby offsetting the influence of part of the limit spring on the floating of the floating plate, making it easier for floating objects to enter the storage groove.

[0013] Optionally, the floating plate is provided with a sliding plate, which is located on the side of the floating plate away from the bottom of the water storage chamber. The sliding plate slides on the floating plate. The sliding direction of the sliding plate is the direction close to the connection between the floating plate and the wall of the water storage chamber. The sliding plate structure is consistent with the floating plate.

[0014] By adopting the above technical solution, in actual use, floating impurities are evenly distributed on the surface of the liquid, so a sliding plate is provided. When the liquid level drops, the sliding plate moves toward the direction close to the receiving tank and pushes the impurities toward the direction close to the receiving tank. In this way, it is easy to guide the impurities into the receiving tank.

[0015] Optionally, the sliding plate is provided with a fixed magnet 1, which is located on the side of the sliding plate away from the connection between the floating plate and the water storage chamber, the floating plate is provided with a fixed plate, the fixed plate is located on the side of the floating plate provided with the sliding plate, and is located on the side of the fixed magnet 1 away from the sliding plate, the fixed plate is provided with a fixed magnet 2, and the magnetic forces of the fixed magnet 2 and the fixed magnet 1 attract each other.

[0016] By adopting the above technical solution, fixed magnet one and fixed magnet two are set, so that when the floating block is tilted, the sliding plate remains connected to the fixed plate for a certain period of time. As the tilt angle of the floating block increases, the magnetic force of fixed magnet one and fixed magnet two is insufficient to make fixed magnet one and fixed magnet two adsorb, and the sliding plate is separated from the fixed plate and the floating impurities are pushed. In this way, the pushing effect of the sliding plate on the impurities is easily improved.

[0017] Optionally, the water storage chamber wall is provided with a delay block, the delay block is located on the side of the water storage chamber wall away from the receiving groove, the distance between the delay block and the bottom of the water storage chamber is greater than the distance between the receiving groove and the bottom of the water storage chamber, the delay block is provided with a delay magnet 1, the fixed plate is provided with a delay magnet 2, the magnetic forces of the delay magnet 1 and the delay magnet 2 attract each other, the floating plate is provided with a drainage hole, the drainage hole passes through the floating plate, and the drainage hole is for liquid to pass through.

[0018] By adopting the above technical solution and setting a delay block, the float plate is kept inclined when the liquid level drops after the float plate rotates to the highest point. In this way, the situation where impurities move to the bottom of the float plate as the liquid level drops is reduced, which facilitates the collection of impurities.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. A storage tank is provided to store floating impurities in the water storage chamber. When it is necessary to remove floating impurities, it is only necessary to make the liquid level in the water storage chamber lower than the height of the storage tank, and then remove the floating impurities in the storage tank. This arrangement facilitates centralized treatment of floating objects and other impurities, making overall impurity removal more convenient. Secondly, when the liquid level drops, the storage tank is closed by the closing member, which reduces the situation where impurities in the storage tank return to the water storage chamber;

[0021] 2. Fixed magnet 1 and fixed magnet 2 are arranged so that when the floating block is tilted, the sliding plate remains connected to the fixed plate for a certain period of time. As the tilt angle of the floating block increases, the magnetic force of fixed magnet 1 and fixed magnet 2 is insufficient to make fixed magnet 1 and fixed magnet 2 adsorb, and the sliding plate is separated from the fixed plate and the floating impurities are pushed. In this way, the pushing effect of the sliding plate on the impurities is improved;

[0022] 3. A delay block is set up, through which the float plate is kept tilted when the liquid level drops after the float plate rotates to the highest point. In this way, the impurities are reduced from moving to the bottom of the float plate as the liquid level drops, making it easier to collect the impurities. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The wall of the water storage chamber 2 is provided with a receiving groove 8, which is located at the side of the connection between the floating plate 5 and the wall of the water storage chamber 2 away from the bottom of the water storage chamber 2. The rotation direction of the floating plate 5 is close to the bottom of the receiving groove 8. The notch of the receiving groove 8 is provided with a stopper 9, which is used to close the receiving groove 8. When the liquid level of the water storage chamber 2 is lower than the position of the receiving groove 8, the stopper 9 closes the receiving groove 8. When the liquid level of the water storage chamber 2 is higher than the receiving groove 8, the receiving groove 8 is connected to the water storage chamber 2. In actual use, a cleaning hole 12 can be provided at the bottom of the receiving groove 8. The cleaning hole 12 passes through the tank body 1. A closing cover 13 is provided at one end of the cleaning hole 12 away from the receiving groove 8. The closing cover 13 is used to close the cleaning hole 12.
