Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage facility technology, specifically a power-free mobile self-cleaning water conveyor. Background Technology
[0002] Currently, rainwater treatment within chemical plant containment dikes commonly employs centrifugal pumps to directly discharge the main accumulated water, supplemented by stratified open ditch treatment of residual wastewater. The centrifugal pumps used to extract the main accumulated water are typically temporary electric submersible pumps. These require temporary power connection during operation, and due to the small volume of water, two people are needed to monitor and operate them, resulting in a waste of manpower and electrical resources. Furthermore, due to the hazardous nature of chemical processes, stringent requirements are placed on the insulation level and special operational management of the pumps. In addition, the amount of rainwater during production is highly unpredictable due to seasonal variations, and the accumulated water contains many impurities, placing high demands on equipment performance and making the purchase of specialized equipment uneconomical.

The end of the water inlet pipe is submerged in the accumulated water, and during operation, the end of the water inlet pipe is higher than the end of the water outlet pipe. Casters are connected to the outside of the cylinder body.
[0006] Furthermore, the main body of the cylinder has a cylindrical cavity structure, and the bottom of the cylinder has a conical structure.
[0007] Furthermore, the downward-sloping mesh surface at the top of the filter barrel has a horizontal tilt angle of <45°.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.
[0021] See Figure 1This embodiment proposes a power-free mobile self-cleaning water conveyor, including a water replenishment funnel 1, a water replenishment valve 2, a water inlet interface 3, a water inlet valve 4, a drain valve 5, a water outlet interface 6, a sewage discharge valve 7, a filter screen bucket 8, a sludge removal port 9, a pipeline support 10, a cylinder 11, a base 12, a handle 13, and a moving wheel 14.
[0022] The main body of the cylinder 11 is a cylindrical cavity structure, and the bottom of the cylinder 11 is a conical structure. A sludge removal port 9 is provided at the lowest point of the bottom of the cylinder 11 for discharging sludge and impurities. A frustum-shaped base 12 is connected to the outer wall of the bottom of the conical structure of the cylinder 11; symmetrically rotatable casters 14 are connected to both sides of the base 12; the casters 14 facilitate the movement of the entire water conveyor; symmetrical handles 13 are provided on the outer wall of the main body of the cylinder 11, which also facilitate the movement of the water conveyor.
[0023] A sealing cap is installed at the top of the cylinder 11, and a water replenishment funnel 1 is connected to the sealing cap. A water replenishment valve 2 is installed at the interface between the water replenishment funnel 1 and the sealing cap. Water is replenished into the cylinder 11 through the water replenishment funnel 1, so that the water level inside the cylinder 11 reaches a level that can achieve a siphon effect. The water replenishment funnel 1 not only facilitates water replenishment operations, but also allows a small amount of water to be stored in the water replenishment funnel 1 during operation for water sealing, ensuring good sealing of the entire device. By manually replenishing water and storing energy, gravitational potential energy is converted into kinetic energy for transport, forming a siphon effect, thus avoiding the need for additional power sources.
[0024] A filter screen barrel 8 is connected to the inner wall of the cylinder 11. The filter screen barrel 8 is a fully mesh barrel structure. The top of the filter screen barrel 8 is a downward-sloping mesh surface with a horizontal tilt angle of <45°. A water inlet 3 is provided above the main body of the cylinder 11. A water outlet 6 is provided below the main body of the cylinder 11. A 45° elbow is connected to the water inlet 3. The 45° elbow is located above the filter screen barrel 8. The water flow entering from the water inlet 3 is used to rinse the upper surface of the filter screen barrel 8 to complete self-cleaning. The filter screens on the sides and bottom of the filter screen barrel 8 effectively increase the filtration area while completing self-cleaning of the filter screens by gravity and water flow during sewage discharge.
[0025] A water inlet pipe 15 is connected to the water inlet interface 3, and a water inlet valve 4 is installed on the water inlet pipe 15; a water outlet pipe 16 is connected to the water outlet interface 6, and a drain valve 5 is installed on the water outlet pipe 16; during use, the end of the water inlet pipe 15 is submerged in the accumulated water, and the end of the water outlet pipe 16 is connected to the external water treatment facility; the end of the water inlet pipe 15 is higher than the end of the water outlet pipe 16 during operation.
[0026] The other end of the water outlet pipe 16 extends into the cylinder 11; the water inlet pipe 15 and the water outlet pipe 16 located outside the cylinder 11 are both fixed to the base 12 by the pipeline support 10.
[0027] The outlet pipe 16 is also connected to a drain pipe 17; a drain valve 7 is installed on the drain pipe 17; the other end of the drain pipe 17 is connected to the conical structure at the bottom of the cylinder 11. A sludge removal port 9 is provided and equipped with a drain valve 7; the accumulated water is used to rinse and clean the filter screen bucket 8, preventing clogging and reducing cleaning costs; during the use of the water conveyor, the drain valve 7 is in the closed state. Before the water conveyor is stopped, the drain valve 7 is opened to return the accumulated water from the outlet pipe 16 to the bottom of the cylinder 11 through the drain pipe 17, and finally discharged through the sludge removal port 9.
[0028] A method for operating a power-free, mobile, self-cleaning water conveyor:
[0029] Based on available materials and actual needs, assemble a suitable power-free mobile self-cleaning water conveyor, ensuring the upper sealing cover and bottom sludge removal port 9 are securely fastened and well-sealed; install suitable rubber hoses (inlet pipe 15 and outlet pipe 16, self-locking interfaces can be selected for later reuse) on the inlet port 3 and outlet port 6, ensuring the outlet pipe 16 port is lower than the inlet pipe 15 port. Main operating steps:
[0030] (1) Close the inlet valve 4, drain valve 5, and drain valve 7, and open the water supply valve 2;
[0031] (2) Manually fill the cylinder 11 with water, and then fill the inlet pipe 15 and outlet pipe 16 with water and vent air in sequence;
[0032] (3) After filling with water, close the water supply valve 2, and open the water inlet valve 4 and the drain valve 5 in sequence (the interval should not be too long). The device will start normally and drain water without power by using the siphon effect.
[0033] (4) Before stopping use, open the drain valve 7 and close the drain valve 5 to flush out the accumulated sludge.
[0034] (5) After use, close the inlet valve 4, drain valve 5, sewage valve 7 and water supply valve 2 to reduce the amount of water to be injected later. In winter when the temperature is low and when dredging, the dredging port 9 needs to be opened to drain the water. The dredging port 9 is used for daily inspection and maintenance.
[0035] Note: The key to starting the equipment is the existence of a height difference and good overall sealing. During operation, especially ensure that the water supply valve 2 is closed, and a small amount of water can be stored in the water supply funnel 1 for water sealing.
[0036] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
