Description

Technical Field

[0001] This utility model relates to the field of water storage tank technology, specifically a high-pressure water gun level control device. Background Technology

[0002] High-pressure water guns are widely used in industrial cleaning, fire fighting, and municipal sanitation. A stable water supply from their storage tank is crucial for ensuring normal operation. In practical applications, the water level control and water quality of the storage tank directly affect the working efficiency and lifespan of the high-pressure water gun. Currently, existing storage tanks typically use ball valves for water replenishment. However, due to the potential presence of impurities in the water, these impurities can easily clog the ball valve over time, affecting water replenishment. Simultaneously, impurities can accumulate at the bottom of the storage tank and easily enter the high-pressure water gun with the water flow, causing pipe blockage or mechanical wear, ultimately damaging the equipment. Furthermore, because the ball valve is located inside the tank, repairs after blockage are difficult, complex, and time-consuming. Especially in scenarios where high-pressure water guns are used frequently, frequent maintenance severely impacts the continuity of equipment operation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a high-pressure water gun level control device, which solves the technical problem that impurities in the water easily clog the ball valve and high-pressure water gun when the existing water storage tank is replenished.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-pressure water gun level control device, including a water tank and a housing installed inside the water tank. The top of the housing is connected to a water inlet pipe extending to the outside of the water tank. A filter cylinder with an open bottom is fixed inside the housing.

[0007] Preferably, the float assembly includes a fixed post fixed to the bottom of the housing, a movable rod rotatably connected to the bottom of the fixed post, a square frame fixed at one end of the movable rod and slidably connected to a pin, and a float fixed at the other end of the movable rod.

[0008] Preferably, the piston tube has an inlet hole and an outlet hole on the outer wall at the top and bottom, respectively.

[0009] Preferably, an inclined guide ring is fixed on the outer wall of the filter cylinder, the guide ring is located below the filter screen, and a dirt collection groove is provided at the lowest position of the guide ring.

[0010] Preferably, a drain pipe is connected to the outer wall of the housing, which is horizontally corresponding to the position of the sludge collection tank, and a valve is provided on the drain pipe.

[0011] By employing the above technical solution, this utility model provides a high-pressure water gun level control device, which has at least the following beneficial effects:

[0012] 1. This high-pressure water gun level control device, by installing a filter cylinder with a filter screen inside the housing, can trap impurities in the water, preventing impurities from entering the piston tube and causing water replenishment blockage, thus reducing the mechanical failure rate. At the same time, a filter screen cleaning mechanism is set on the outside of the filter cylinder.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] A high-pressure water gun is a device that uses a power unit to pressurize water and then sprays it out through a nozzle to form a high-speed water jet, which has strong impact force and cleaning ability.

[0024] Due to the technical defects of existing technologies, such as the tendency to clog ball valves and high-pressure water guns, please refer to... Figures 1-5 This embodiment provides a high-pressure water gun level control device that can trap impurities in the water, preventing them from entering the piston tube 5 and causing blockages, thus reducing the mechanical failure rate. It also has the advantages of easy maintenance and simple operation. The device includes a water tank 1 and a housing 2 installed inside the water tank 1. A water inlet pipe 3 extending to the outside of the water tank 1 is connected to the top of the housing 2. A filter cylinder 4 with an open bottom is fixed inside the housing 2, and a filter screen 41 is fixed on the outer wall of the filter cylinder 4. A piston tube 5 is fixed at the center of the bottom of the housing 2. The bottom of the piston tube 5... An automatic water replenishment mechanism 6 is provided. A filter screen 41 is fixed on the outer wall of the filter cylinder 4, and a filter screen cleaning mechanism 7 connected to the automatic water replenishment mechanism 6 is provided on the outer side of the filter cylinder 4. When in use, when the water in the water tank 1 decreases with use, the automatic water replenishment mechanism 6 can automatically replenish water into the water tank 1 through the water inlet pipe 3. When replenishing water, impurities in the water can be trapped by the filter screen 41, and the filter screen cleaning mechanism 7 cleans away the impurities trapped on the filter screen 41, avoiding the problem of impurities clogging the filter screen 41 and causing poor water replenishment.

[0025] Traditional water replenishment devices lack an automatic cleaning mechanism. Once clogged with impurities, they require manual disassembly and cleaning, which is cumbersome and affects replenishment efficiency. To address this issue, please refer to... Figure 3 and Figure 4 The filter cleaning mechanism 7 includes a follower rod 71 connected to the automatic water replenishment mechanism 6. The follower rod 71 is movably connected to the top of the filter cylinder 4. A scraper ring 73 is fixed to the top of the follower rod 71 through a connecting rod 72. The scraper ring 73 is attached to the outside of the filter screen 41. The follower rod 71 can be controlled to move up and down by the power of the automatic water replenishment mechanism 6. The follower rod 71 drives the scraper ring 73 to move up and down through the connecting rod 72, thereby scraping off the impurities attached to the filter screen 41, avoiding the problem of impurities clogging the filter screen 41 and affecting water replenishment. It has the advantage of automatic cleaning.

[0026] The existing water storage tank 1 relies heavily on manual monitoring of the water level. When the water level drops, the water supply valve needs to be opened manually. If monitoring is not timely, water tank 1 may run out of water, causing the high-pressure water gun to stop due to water shortage or the equipment to run dry and be damaged. To address this issue, please refer to [the relevant documentation / reference]. Figure 3 , Figure 4 and Figure 5 The automatic water replenishment mechanism 6 includes a piston column 61 movably connected to the bottom of the piston tube 5. A piston 62 is fixedly mounted on the top of the piston column 61 and movably disposed inside the piston tube 5. The piston 62 is fixedly connected to a follower rod 71. A groove is formed at the bottom of the piston column 61, and a pin 63 is fixedly mounted within the groove. A float assembly 64 is movably connected to the bottom of the movable column via the pin 63. The float assembly 64 is fixedly mounted at the bottom of the housing 2. Specifically, the float assembly 64 includes a fixed column 641 fixedly connected to the bottom of the housing 2. A movable rod 642 is rotatably connected to the bottom of the fixed column 641. One end of the movable rod 642 is fixedly provided with a square frame 643 that is slidably connected to the pin 63. The other end of the movable rod 642 is fixed with a float 644. When the water level in the water tank 1 is low, the float 644 descends with the liquid level. At this time, the movable rod 642 rotates and pushes the piston column 61 upward under the action of the square frame 643 and the pin 63. The piston column 61 drives the piston 62 upward. When the piston 62 is misaligned with the water inlet 51 on the piston tube 5, the water inlet 51 opens, and water can enter the piston tube 5 and be discharged through the water outlet 52 at the bottom, realizing automatic water replenishment inside the water tank 1. When the water replenishment is completed, the float 644 rises with the liquid level and causes the piston 62 to move downward. The piston 62 re-blocks the water inlet 51 of the piston tube 5, thereby stopping the water intake.

[0027] Furthermore, a water inlet hole 51 and a water outlet hole 52 are respectively provided on the outer wall of the top and bottom of the piston tube 5; the water inlet hole 51 and the water outlet hole 52 can be used for water inlet and outlet.

[0028] After the impurities on the filter screen 41 are cleaned off by the scraper ring 73, they are located at the bottom of the inner side of the housing 2, making them difficult to remove and thus still causing cleaning difficulties. To address this issue, an inclined guide ring 74 is fixed on the outer wall of the filter cylinder 4, positioned below the filter screen 41, with a dirt collection trough 741 located at its lowest point. Under the action of the guide ring 74, the cleaned-off impurities can slide down the inclined guide ring 74 into the dirt collection trough 741. Furthermore, a drain pipe 75 is connected to the outer wall of the housing 2, horizontally corresponding to the position of the dirt collection trough 741, and a valve is installed on the drain pipe 75. When the valve is opened, water is discharged through the drain pipe 75, which, while draining the water, also carries away the impurities in the dirt collection trough 741, thus achieving the removal and cleaning of impurities.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
