Description

Technical Field

[0001] The utility model belongs to the technical field of water tanks, and particularly relates to a steel plate water tank with a stainless steel lining. Background Technique

[0002] A fire fighting water tank refers to a fire fighting facility that provides water source for the fire brigade during fire fighting and rescue activities. The fire fighting water tank stores water. On the one hand, it fills the fire fighting water supply pipeline with water, saves the time for the fire fighting water pump to fill the pipeline after starting, and wins time for extinguishing the fire. On the other hand, the pressurization, pressure stabilization system and water tank set on the roof can ensure the full water column of the fire fighting water gun, which plays a decisive role in the success or failure of extinguishing the initial fire. At present, there are many options for the water tank materials, and the common materials include steel plates, stainless steel, reinforced concrete, fiberglass, enameled steel plates, etc. However, they each have their own advantages and disadvantages. Among them, the steel plate water tank ensures the maximum pressure-bearing requirement of the water tank, saves materials, and meets the requirements of the water tank's beauty and use, so it is widely used. The steel plate water tank for fire fighting needs to ensure that the water volume in it is within a certain range, that is, the water level in it needs to be ensured within a certain range to ensure ready-to-use at any time. At present, the water level in the water tank is mostly observed manually, and then the water replenishment operation is carried out, which is prone to the situation of undetected or untimely water replenishment.

[0003] In view of the above problems, the utility model patent with the patent publication number CN215340845U discloses a fire fighting water tank liquid level control device. When the water level in the water tank drops, the buoyancy block and the lifting rod are driven to descend under the action of the compression spring. After reaching the set water level, the starting block is driven to contact the upper side of the control switch, and the water supply pump is started to supply water into the water tank. As the water level in the water tank rises, the buoyancy block and the lifting rod rise together until the lower side of the closing fast contact control switch is reached when the target water level is reached, and the water supply pump stops working. It effectively solves the problem of maintaining and automatically replenishing the water volume in the water tank. However, during the lifting and lowering adjustment process of the lifting rod, limited by the length of the lifting rod and the space occupation problem, the lifting rod cannot be too long, so the adjustment range of the set water level is small. Summary of the Invention

[0004] The utility model provides a steel plate water tank with a stainless steel lining to solve the problem that when the existing steel plate water tank for fire fighting realizes water volume maintenance and automatic replenishment, limited by space, the adjustment range of the set water level for automatic water replenishment is small, which is not conducive to flexibly adjusting the automatic water replenishment situation of the water tank. Through the lifting and lowering of the water level in the box body, the spring drives the adjusting rod to lift and lower. Then, in the connected main pipe, delivery pipe and cylinder body, using the principle of hydraulic transmission, the lifting and lowering of the adjusting rod drives the adjusting block to lift and lower to realize the start-stop adjustment of the water pump, making the lifting rod become a telescopic structure and improving the adjustment range of the automatically replenished water level.

[0005] In order to achieve the above object, the technical solution of the utility model is:

[0006] A steel plate water tank with a stainless steel inner lining, comprising a box body and an automatic water replenishing device. An inner lining is fixedly arranged on the inner wall of the box body to prevent the box body from being corroded and damaged. The automatic water replenishing device includes a water pump. The water outlet of the water pump extends into the box body. One side of the water pump is electrically connected to a water supply switch. A main pipe is fixedly and communicatively arranged on the top of the box body. A sealing cover is fixedly arranged at the upper end of the main pipe. An adjusting rod is sleeved at the lower end of the main pipe. The lower end of the adjusting rod extends out of the main pipe and fixedly arranges a floating block. A spring is fixedly arranged between the floating block and the inner top surface of the box body. The spring is sleeved on the adjusting rod. The main pipe is communicatively arranged with a delivery pipe. A cylinder body is also fixedly arranged on the top of the box body. The cylinder body is communicatively connected with the delivery pipe. A piston rod is sleeved at the upper end of the cylinder body. The piston rod extends out of the cylinder body and fixedly connects a horizontally arranged U-shaped adjusting block. The water supply switch is located between the two side plates of the adjusting block. The main pipe, the delivery pipe, and the cylinder body are all filled with a delivery liquid. Under the combined action of buoyancy and the spring, the floating block rises and falls with the liquid level in the box body, and then uses the delivery liquid to achieve hydraulic transmission, driving the piston rod to rise and fall, so as to realize the start and stop control of the water pump and realize automatic water replenishment in the box body.

[0007] Preferably, a net plate is fixedly arranged in the middle of the main pipe. A plurality of mesh holes are arranged on the net plate. The net plate divides the inside of the main pipe into a first chamber and a second chamber. The lower end of the first chamber extends into the box body and slidably sleeves the adjusting rod. The lower end of the adjusting rod extends out of the first chamber and fixedly connects the floating block. Through the setting of the net plate, when the adjusting rod expands and contracts in the first chamber, the delivery liquid in the first chamber and the second chamber is always kept in a communicative state, ensuring the hydraulic transmission effect.

[0008] Preferably, the two ends of the delivery pipe are respectively communicatively connected to the lower end of the second chamber and the lower end of the cylinder body, ensuring the communication between the main pipe and the cylinder body.

[0009] Preferably, the spring drives the floating block to move downward. The elastic force of the spring is less than the buoyancy of the floating block on the water surface in the box body, ensuring that the floating block is located on the water surface in the box body.

[0010] Preferably, the inner lining is a structure made of stainless steel material and fitting the inner wall of the box body. The water in the box body is separated from the steel plate by the inner lining, avoiding corrosion and damage to the box body.

[0011] Preferably, the adjusting block includes a first horizontal plate, a second horizontal plate, and a vertical plate. The lower side of the first horizontal plate is fixedly connected to the piston rod, and the upper side is fixedly connected to the vertical plate. The second horizontal plate is fixedly connected above the vertical plate. The water supply switch is located between the first horizontal plate and the second horizontal plate. The piston rod drives the adjusting block to rise and fall, and then the first horizontal plate and the second horizontal plate respectively start and stop the water supply switch.

[0012] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] During the use of the utility model, as the water level in the box body drops, the floating block drops with the water level under the action of the spring elasticity, driving the adjusting rod to move downward. As a result, the adjusting rod reduces the space occupied in the first chamber. Under the action of pressure, the conveying liquid in the cylinder body is sucked into the main pipe. Then, the piston rod drops, driving the adjusting block to drop. The second horizontal plate contacts the upper side of the water supply switch, starting the water pump to supply water to the box body. As the water level in the box body rises, the floating block rises under the action of buoyancy, driving the adjusting rod to rise in the first chamber. The conveying liquid is squeezed through the mesh holes of the mesh plate and the conveying pipe into the cylinder body. Then, the conveying liquid pushes the piston rod upward, driving the adjusting block to move upward until the first horizontal plate contacts the lower side of the water supply switch, closing the water pump and stopping the water supply to the box body;

[0014] Thus, the utility model realizes automatically supplying water to the box body according to the water level situation in the box body and automatically stopping the water supply when reaching the corresponding water level, keeping the water volume in the box body within a certain range. At the same time, the hydraulic transmission effect is achieved through the conveying liquid, so that there is no need to set the main pipe and the adjusting rod too long, saving the space occupied by the device. Furthermore, the water level difference between the water replenishment level and the stop water replenishment level can be enlarged, improving the flexibility of the water level setting for automatic water replenishment of the box body;

[0015] Meanwhile, by arranging a mesh plate with a plurality of large mesh holes, the conveying liquid can directly flow in the first chamber and the second chamber through the mesh holes, which can effectively reduce the length setting of the main pipe and avoid energy waste caused by the height difference of the conveying liquid above the adjusting rod during the adjustment process;

[0016] By melting a stainless steel lining on the inner wall of the box body, the utility model can be used for storing drinking water to ensure the water quality of the stored water. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the utility model in conjunction with the drawings and the specific embodiments:

[0022] As Figures 1 to 3 shown, this embodiment provides a steel plate water tank with a stainless steel lining, including a box body 1 and an automatic water replenishing device. The box body 1 is made of galvanized steel plate. The box body 1 has a structure of a steel plate water tank commonly used in the prior art such as a cylindrical shape or a cuboid shape. A drainage pipe is connected to the lower end of the box body 1. A lining (not shown in the figure) is fixedly arranged on the inner wall of the box body 1 to prevent the box body 1 from being corroded and damaged. The lining is a structure made of stainless steel material and fitted to the inner wall of the box body 1. The lining layer made of 304 stainless steel is hot-melted on the inner wall of the box body 1, thereby avoiding the problem of poor water quality when the galvanized steel plate water tank is used for storing drinking water, and at the same time avoiding the problem that the box body 1 is not resistant to acid and alkali corrosion when the box body 1 is made of stainless steel material (since during the application process, part of the box body 1 is below the ground, the galvanized steel plate material can avoid the corrosion problem caused by the soil environment). This enables the galvanized steel plate water tank to be used not only for storing fire-fighting water but also for storing drinking water on this basis.

[0023] The automatic water replenishing device includes a water pump 2. The water outlet of the water pump 2 extends into the box body 1. A water supply switch 3 is electrically connected to one side of the water pump 2 to control the start and stop of the water pump 2 by the water supply switch 3. A main pipe 4 is fixedly connected to the top of the box body 1. A sealing cover 5 is fixedly arranged at the upper end of the main pipe 4 to ensure the upper end of the main pipe 4 is sealed. An adjusting rod 6 is sleeved at the lower end of the main pipe 4. The lower end of the adjusting rod 6 extends out of the main pipe 4 and is fixedly provided with a floating block 7. The adjusting rod 6 can stretch and contract at the lower end of the main pipe 4. The floating block 7 can adopt a structure such as a hollow airbag that can float on the water surface. A spring 8 is fixedly arranged between the floating block 7 and the inner top surface of the box body 1. The spring 8 is sleeved on the adjusting rod 6. The spring 8 drives the floating block 7 to move downward. The elastic force of the spring 8 is less than the buoyancy of the floating block 7 on the water surface in the box body 1. When the water level in the box body 1 rises, since the buoyancy received by the floating block 7 is greater than the elastic force of the spring 8, the floating block 7 floats upward, driving the adjusting rod 6 to rise and retracting into the main pipe 4. When the water level in the box body 1 drops, the floating block 7 no longer receives an upward buoyancy force, and under the action of the elastic force of the spring 8, it always stays on the water surface in the box body 1.

[0024] The main pipe 4 is connected with a delivery pipe 9. A cylinder 10 is fixedly arranged on the top of the box body 1. The cylinder 10 is communicated with the delivery pipe 9. The two ends of the delivery pipe 9 are respectively communicated with the lower end of the second chamber 15 and the lower end of the cylinder 10. A piston rod 11 is sleeved on the upper end of the cylinder 10. The piston rod 11 extends out of the cylinder 10 and is fixedly connected with a horizontally arranged U-shaped adjusting block 12. The water supply switch 3 is located between the two side plates of the adjusting block 12. The adjusting block 12 includes a first horizontal plate, a second horizontal plate and a vertical plate. The lower side of the first horizontal plate is fixedly connected with the piston rod 11, and the upper side is fixedly connected with the vertical plate. The second horizontal plate is fixedly connected above the vertical plate. The water supply switch 3 is located between the first horizontal plate and the second horizontal plate. When the piston rod moves up and down, it drives the adjusting block 12 to move up and down synchronously. When the second horizontal plate contacts the upper side of the water supply switch 3, the water pump 2 starts to supply water into the box body 1. When the first horizontal plate contacts the lower side of the water supply switch 3, the water pump 2 stops supplying water into the box body 1.

[0025] The main pipe 4, the delivery pipe 9 and the cylinder 10 are all filled with a transmission fluid. The transmission fluid is hydraulic oil or other liquids that can achieve hydraulic transmission and meet the requirements of the present utility model in the prior art. When the adjusting rod 6 descends, a negative pressure is formed in the main pipe 4. At the same time, under the action of the atmospheric pressure, the piston rod 11 descends, and the transmission fluid in the cylinder 10 is transported to the main pipe 4 through the delivery pipe 9. When the adjusting rod 6 ascends, the transmission fluid in the main pipe 4 is extruded and transported to the cylinder 10 through the delivery pipe 9. Then, under the pressure of the transmission fluid, the piston rod 11 ascends.

[0026] A net plate 13 is fixedly arranged in the middle of the main pipe 4. A plurality of mesh holes are arranged on the net plate 13. The net plate 13 divides the interior of the main pipe 4 into a first chamber 14 and a second chamber 15. The first chamber 14 and the second chamber 15 are communicated through the mesh holes on the net plate 13. There is a gap between the upper end of the net plate 13 and the sealing cover 5. The lower end of the first chamber 14 extends into the box body 1 and is slidably sleeved with an adjusting rod 6. The lower end of the adjusting rod 6 extends out of the first chamber 14 and is fixedly connected with a floating block 7. When the floating block 7 ascends, it drives the adjusting rod 6 to retract into the main pipe 4 and the first chamber 14, and squeezes the transmission fluid in the first chamber 14 into the second chamber 15 through the mesh holes. The transmission fluid in the second chamber 15 is transported to the cylinder 10 through the delivery pipe 9 and jacks up the piston rod 11 upward. When the piston rod 11 descends, the transmission fluid in the cylinder 10 is squeezed and transported to the second chamber 15 through the delivery pipe 9. The transmission fluid in the second chamber 15 enters the first chamber 14 through the mesh holes on the net plate 13.

[0027] During use, as the water level in the box body 1 drops, the floating block 7 moves downward under the elastic force of the spring 8, driving the adjusting rod 6 to move downward. As a result, a negative pressure is formed in the first chamber 14. Under the action of the negative pressure, the conveying liquid is conveyed from the second chamber 15 to the first chamber 14 through the mesh plate 13. The conveying liquid in the conveying pipe 9 is conveyed to the second chamber 15, and the conveying liquid in the cylinder body 10 is conveyed to the conveying pipe 9. Then, the adjusting block 12 and the piston rod 11 move downward under the action of atmospheric pressure and the negative pressure adsorption in the cylinder body 10. As the water level in the box body 1 continues to drop, when the adjusting block 12 moves downward until it contacts the upper side of the water supply switch 3 on the second cross plate, the water pump 2 starts to supply water to the box body 1, and the water level in the box body 1 rises. Since the buoyancy force on the floating block 7 is greater than the elastic force of the spring 8, the floating block 7 moves upward, driving the adjusting rod 6 to move upward. The adjusting rod 6 retracts into the first chamber 14, squeezing the conveying liquid, which is then conveyed from the first chamber 14 to the second chamber 15 and the conveying pipe 9 in sequence and then to the cylinder body 10. It is pressurized in the cylinder body 10 and pushes the piston rod 11 upward, thereby driving the piston rod 11 and the adjusting block 12 to move upward. As the water level in the box body 1 continues to rise, when the adjusting block 12 moves upward until the first cross plate contacts the lower side of the water supply switch 3, the water pump 2 stops supplying water to the box body 1.

[0028] The above-described embodiments are only the preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
