Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a device and method for preventing water hoses of large and medium diameter from falling. Background Technology

[0002] On construction sites, especially where the ground is hardened and the site is severely waterlogged, large-diameter pressure booster pumps are often used in conjunction with temporary water hoses to drain water because there are few temporary drainage ditches built on the site and the drainage ditches have different elevations.

[0003] After the hose is connected to the pressure booster pump, it is hoisted into the sump along with the pump body. The construction speed is fast, and there is basically no faster alternative, making it particularly suitable for temporary on-site drainage. However, the hose is a flexible pipe with no rigidity. When the pump in a large temporary sump (both in depth and width are greater than 3 meters) is started, the temporary hose connected to the pump is prone to slipping due to gravity, requiring five or six workers to monitor it.

[0004] When the weight G (mainly the weight of the water) of the suspended section of the hose in the large temporary water collection pit is greater than the pulling force (F×COSθ, where θ is the angle of inclination of the hose) exerted by the worker outside the large temporary water collection pit on the hose, the hose will slip into the water collection pit, resulting in pumping failure. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, a device and method for preventing large and medium-sized water hoses from falling is provided to solve the problem that existing large-diameter water hoses are prone to slipping into puddles when used on construction sites.

[0006] To achieve the above objectives, a device for preventing water hoses from falling off in large and medium-sized caliber systems is provided, comprising:

[0007] A base frame for installing between a sump and an open drainage ditch, the base frame having a first side close to the sump and a second side away from the sump, a clamping plate being vertically mounted on the second side, a clamping space for clamping a water hose being formed between the clamping plate and the second side of the base frame, and a drive mechanism for driving the clamping plate being mounted on the second side.

[0008] A pressure sensor for collecting the pressure value of the water hose is installed on the first side;

[0009] A controller, connected to the drive mechanism and the pressure sensor, controls the drive mechanism to raise the clamping plate when the pressure value is greater than the initial pressure value of the hose under no-load conditions, so that the aperture of the clamping space is adapted to the outer diameter of the hose under full-load conditions.

[0010] Furthermore, multiple guide posts are vertically arranged on the second side, and multiple through holes are opened in the clamping plate. The guide posts are slidably arranged in the through holes, and the water hose is inserted between the two guide posts.

[0011] Furthermore, the driving mechanism is an electro-hydraulic push rod, which has a fixed end and a telescopic end. The fixed end is connected to the top of the guide column, and the telescopic end is connected to the clamping plate.

[0012] Furthermore, a locking mechanism for locking onto the ground is installed on the bottom frame.

[0013] Furthermore, the locking mechanism includes:

[0014] The drill rod is set vertically, and through holes are opened at opposite ends of the bottom frame. The drill rod is rotatably inserted into the through holes, and a polygonal socket hole is opened at the upper part of the drill rod.

[0015] A plug rod, the lower end of which is slidably disposed in the socket, and a lifter for driving the plug rod is installed between the lower end of the plug rod and the socket.

[0016] An electric motor is connected to the upper end of the insertion rod to drive the drill rod to rotate.

[0017] Furthermore, the drill pipe has helical blades formed on its exterior.

[0018] Furthermore, the lifting device has an electro-hydraulic push rod.

[0019] This invention provides a method for preventing water hose falls using a device for preventing falls in large and medium-sized caliber water hoses, comprising the following steps:

[0020] The base frame of the anti-fall device for large and medium-sized caliber water hoses is installed on the ground between the sump and the drainage ditch.

[0021] One end of the hose is connected to the lift pump, the middle part of the hose is placed on the bottom frame and passed through the clamping space, and the other end of the hose is connected to the drainage ditch, so that the middle part of the hose is locked to the ground through the bottom frame.

[0022] When the booster pump is turned on, the water in the sump is transported from one end of the hose to the middle of the hose.

[0023] The pressure sensor collects the pressure value at the middle of the water hose on the bottom frame in real time;

[0024] The controller acquires the pressure value. When the pressure value is greater than the initial pressure value of the hose under no-load conditions, the controller controls the drive mechanism to raise the clamping plate so that the aperture of the clamping space is adapted to the outer diameter of the hose under full load conditions.

[0025] The beneficial effects of this invention are as follows: The anti-fall device for large and medium-sized diameter water hoses uses a pressure sensor to collect the pressure value of the water hose. When the pressure value collected by the pressure sensor changes significantly, the controller activates the drive mechanism, causing the clamping plate to rise and gradually increasing the diameter of the clamping space. At this time, the water pumped into the water hose by the lift pump reaches the clamping hole, ensuring that the clamping space still has a limiting effect on the water hose without restricting the flow rate of the water inside the water hose. This anti-fall device for large and medium-sized diameter water hoses achieves both temporary locking of the water hose, preventing it from falling into the sump when the lift pump is initially turned on, and allows for unattended operation of the water hose, reducing construction costs.

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 3 As shown, the present invention provides a device for preventing water hoses from falling in large and medium caliber, comprising: a base frame 1, a pressure sensor 2, and a controller.

[0033] In use, the bottom frame 1 is installed between the sump 5 and the drainage ditch 6.

[0034] In a preferred embodiment, the base frame 1 is rectangular. The base frame is formed by welding steel profiles and has a certain weight.

[0035] Specifically, the base frame 1 has a first side close to the sump 5 and a second side away from the sump 5. A clamping plate 12 is movably mounted on the second side of the base frame 1. A clamping space for holding the hose 4 is formed between the clamping plate 12 and the second side of the base frame 1. A drive mechanism is mounted on the second side of the base frame 1. The drive mechanism drives the clamping plate 12 to move it up and down, thereby adapting the aperture of the clamping space to the outer diameter of the hose.

[0036] Pressure sensor 2 is installed on the first side of the base frame 1. Pressure sensor 2 is used to collect the pressure value of the water hose 4. Specifically, pressure sensor 2 is installed on the upper surface of the first side of the base frame, and the water hose rests on the pressure sensor. When the water hose is fully loaded with water in the sump, the weight of the water hose and the water inside it will increase significantly, causing a large change in the pressure value collected by the pressure sensor.

[0037] The controller is connected to the drive mechanism and the pressure sensor 2. When the pressure value is greater than the initial pressure value of the water hose 4 under no-load conditions, the controller controls the drive mechanism to raise the clamping plate 12 so that the aperture of the clamping space is adapted to the outer diameter of the water hose 4 under full load conditions.

[0038] When the water hose is unloaded, its weight only includes the weight of the hose itself. However, when the water hose is connected to a booster pump, and the booster pump draws water into the hose, the weight of the hose includes the weight of the hose itself and the water inside.

[0039] When the pressure value collected by the pressure sensor changes significantly, the controller activates the drive mechanism, causing the clamping plate to rise and gradually increasing the diameter of the clamping space. At this point, the water pumped into the hose by the lift pump reaches the clamping hole, ensuring that the clamping space still provides a limiting effect on the hose without restricting the flow rate of the water inside the hose. This invention, a hose anti-fall device for medium and large diameter hoses, achieves temporary locking of the hose, preventing it from falling into the sump when the lift pump is initially activated, and also allows for unattended operation of the hose, reducing construction costs.

[0040] In a preferred embodiment, multiple guide posts 11 are vertically mounted on the second side of the bottom frame. Multiple through holes are provided in the clamping plate 12. The guide posts 11 slide within the through holes of the clamping plate. The guide posts can move axially along the through holes of the clamping plate. A water hose 4 passes between two guide posts 11.

[0041] In this embodiment, the driving mechanism is an electro-hydraulic actuator. The electro-hydraulic actuator has a fixed end and a telescopic end. The fixed end of the electro-hydraulic actuator is connected to the top of the guide post 11. The telescopic end of the electro-hydraulic actuator is connected to the clamping plate 12.

[0042] Specifically, a flange is formed at the top of the guide post, and the fixed end of the electro-hydraulic actuator is fixed to the bottom of the flange. The electro-hydraulic actuator is arranged in the same direction as the guide post. The telescopic end of the electro-hydraulic actuator is fixedly connected to the upper surface of the clamping plate.

[0043] As a preferred embodiment, a locking mechanism 3 for locking onto the ground is installed on the bottom frame 1.

[0044] In this embodiment, the locking mechanism 3 includes: a drill rod 31, a insertion rod 32, a motor 34, and a lifter 35.

[0045] The drill pipe 31 is cylindrical. The drill pipe 31 is vertically positioned. (See reference...) Figure 3 As shown, through holes are provided at opposite ends of the bottom frame 1. The drill rod 31 is rotatably inserted into the through holes. A polygonal socket hole is provided on the upper part of the drill rod 31.

[0046] The outer diameter and shape of the insertion rod 32 are adapted to the inner diameter and shape of the socket. The lower end of the insertion rod 32 slides in the socket. A lifting device 35 is installed between the lower end of the insertion rod 32 and the socket. The lifting device 35 is used to drive the insertion rod 32 to move along the axial direction of the drill rod.

[0047] The motor 34 is connected to the upper end of the insertion rod 32 to drive the drill rod 31 to rotate through the insertion rod 32.

[0048] In this embodiment, the motor 34 is mounted on the end of the base frame via a bracket. The motor's output shaft is coaxially connected to the insertion rod. Correspondingly, the motor's output shaft is coaxially arranged with the drill rod. The motor provides rotational power to the drill rod, and the lifting device provides axial pushing and pulling force to the drill rod. When the motor is turned on, the drill rod can drill into the ground below the base frame through the through hole, thereby securely locking the base frame to the ground.

[0049] As a preferred embodiment, the drill pipe 31 has helical blades formed on its outer surface.

[0050] As a preferred implementation, the lifter 35 is an electro-hydraulic push rod.

[0051] This invention provides a method for preventing water hose falls using a device for preventing falls in large and medium-sized caliber water hoses, comprising the following steps:

[0052] S1, The base frame 1 of the anti-fall device for large and medium diameter water hoses 4 is installed on the ground between the water sump 5 and the drainage ditch 6.

[0053] S2. Connect one end of the water hose 4 to the lifting pump 7, place the middle part of the water hose 4 on the bottom frame 1 and pass it through the clamping space, and then connect the other end of the water hose 4 to the drainage ditch 6, so that the middle part of the water hose 4 is locked to the ground through the bottom frame 1.

[0054] S3. Start the booster pump 7, and the water in the sump 5 is transported from one end of the water hose 4 to the middle of the water hose 4.

[0055] S4, Pressure sensor 2 collects the pressure value in the middle of the water hose 4 on the bottom frame 1 in real time.

[0056] S5. The controller acquires the pressure value. When the pressure value is greater than the initial pressure value of the water hose 4 under no-load conditions, the controller controls the drive mechanism to raise the clamping plate 12 so that the aperture of the clamping space is adapted to the outer diameter of the water hose 4 under full-load conditions.

[0057] When using the anti-fall device for large and medium caliber water hoses of the present invention, install it in the following order:

[0058] a. Install the anti-fall device for the water hose at the location shown in the diagram (between the puddles and the drainage ditch), and secure it firmly.

[0059] b. Install the booster pump and the water hoses for sections AB and BC.

[0060] c. Next, connect the CD and D sections of the water hose, place it on the bottom frame, and pass it through the clamping space.

[0061] d. At this time, the pressure value of the water hose is relatively small. The controller controls the drive mechanism to lower the clamping plate and lock the water hose onto the bottom frame.

[0062] e. When the booster pump is started for the first time, when the water hose in section CD is about to be filled with water, if the pressure value collected by the pressure sensor by the controller meets the preset threshold, the controller will start the drive mechanism to raise the clamp plate until the clamp plate no longer affects the drainage of the water hose.

[0063] f. After the pumping is running normally, maintain the above state; whether the pump is started or stopped, the CD section of the water hose will be full of water and will not retract and fall into the water pit.

[0064] This invention relates to an anti-fall device for water hoses in medium and large diameter systems. It temporarily secures the water hose during the initial pumping start-up, preventing it from slipping into the sump. During normal drainage, the device limits the hose's position, ensuring it doesn't slip or swing. The water hose is positioned along a predetermined track, preventing it from swaying during pumping. This provides safe, fast, reliable, and labor-saving drainage at construction sites.

[0065] The anti-fall device for water hoses of the present invention for large and medium diameter hoses is simple and practical, and can effectively fix the water hose and prevent the water hose from slipping and causing pumping failure.

[0066] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
