Description

Technical Field

[0001] The utility model relates to the field of salt pond rainwater discharge, in particular to automatic drainage equipment for salt ponds. Background Art

[0002] Salt ponds are used to produce table salt or industrial salt. The primary function of a salt pond cover is to prevent evaporation and ensure salt concentration. If water accumulates on the salt pond cover over time and is not removed, the weight of the water can damage the cover structure or cause it to sink. Therefore, drainage is necessary. Salt pond cover drainage equipment is primarily used to remove water that has accumulated on the salt pond cover due to rainwater or other factors.

[0003] Most of the existing salt pond drainage devices adopt the form of adding push rods on the guard plates and are manually operated, which requires a lot of manpower, is not only inefficient but also labor-intensive. Utility Model Content

[0004] The utility model provides an automatic salt pond drainage device to solve the technical problems of low drainage efficiency and high labor intensity of existing salt pond drainage devices.

[0005] According to one aspect of the utility model, an automatic drainage device for a salt pond is provided, comprising a drainage box for being arranged in the drain outlet of the salt pond; a lifting device for being arranged above the drain outlet of the salt pond to drive the drainage box to rise and fall; a rope-collecting device comprising a support plate arranged on the drainage box, a steering pulley arranged at both ends of the support plate, and a tightening rope surrounding the drainage box and cooperating with the steering pulley, wherein both ends of the tightening rope are respectively used to connect to a plastic thatch film, and a lifting screw rod for lifting the tightening rope is provided on the support plate.

[0006] With this solution, the drainage box of the automatic salt pond drainage system is installed in the salt pond's drain outlet. A lifting mechanism drives the box up and down to achieve drainage. The rope-collecting mechanism includes a support plate, a diverting pulley, and a take-up rope. The take-up rope is connected to the plastic sheeting. The lifting screw lifts the take-up rope, thereby tightening the plastic sheeting, ensuring a secure seal between the drainage box and preventing water from flowing into the salt pond.

[0007] Optionally, both ends of the tightening rope are provided with hangers, and a guide hole is left at the bottom of the hanger to embed the plastic film that wraps the edge of the hanger.

[0008] With this solution, the design features hangers at both ends of the drawstring, with guide holes at the bottom for inserting the plastic film wrapped around the hangers. This design ensures that the film tightly wraps around the drainage box during drainage, further enhancing the sealing of the system.

[0009] Optionally, hanging slides are vertically provided on both sides of the drainage box, and the hanging is slidably matched with the hanging slides.

[0010] With this solution, the vertical hanging chutes on both sides of the drainage box cooperate with the hanging slides, allowing the hanging to move up and down within the hanging chutes. This design makes the plastic film more stable during the tensioning process, avoiding wrinkles and damage to the film.

[0011] Optionally, a clamping device is provided on the drainage box, and the clamping device includes a fixed baffle, a movable baffle and a driving assembly. A clamping space for the plastic thatch film to pass through is formed between the fixed baffle and the movable baffle, and the driving assembly is used to drive the movable baffle close to the fixed baffle to clamp the plastic thatch film.

[0012] With this solution, the clamping device, mounted on the drainage box, comprises a fixed baffle, a movable baffle, and a drive assembly. A clamping space is formed between the fixed and movable baffles. The drive assembly drives the movable baffle toward the fixed baffle, thereby clamping the plastic film. This design ensures the tightness and stability of the plastic film during drainage.

[0013] Optionally, the driving assembly includes a slider, a first pull rod, a second pull rod and a buoyancy plate. A slide groove is provided at the bottom of the drainage box in a horizontal direction. The slider is fixedly connected to the movable baffle and is slidably provided in the slide groove. One end of the first pull rod is hinged to the slider and the other end is hinged to the buoyancy plate. One end of the second pull rod is fixed in the slide groove and the other end is hinged to the buoyancy plate.

[0014] With this solution, the slider is fixedly connected to the movable baffle and slides within the chute. The buoyancy plate is hinged to the slider and chute via first and second tie rods. When the drainage tank is lowered into the water, the buoyancy plate rises, generating thrust that drives the slider via the tie rods, pushing the movable baffle to clamp the plastic film, achieving automatic clamping and sealing.

[0015] Optionally, a rubber plate is provided on the side of the fixed baffle and the movable baffle that are close to each other.

[0016] Through the above solution, the rubber sheet can provide a better sealing effect, ensuring that the plastic film will not be damaged during the clamping process, while improving the sealing performance.

[0017] Optionally, the lifting device includes a support frame and an electric screw arranged on the support frame, and the electric screw is vertically arranged and connected to the drainage box.

[0018] According to the above solution, the lifting device includes a support frame and an electric screw, which is vertically arranged and connected to the drainage box. By raising and lowering the electric screw, the height of the drainage box can be precisely controlled, thereby realizing intelligent drainage operation.

[0019] Optionally, a water level sensor is provided at the bottom of the drainage tank.

[0020] Through the above solution, the water level can be monitored in real time, providing accurate water level information, and combined with the lifting device of the electric screw to achieve automated and intelligent drainage control.

[0021] Optionally, the drainage box includes a water inlet cylinder, a water collecting cylinder and a drainage pipe connected in sequence, the water inlet cylinder is provided with an opening for connecting with the drain outlet of the salt pool, and the top of the water collecting cylinder is provided with a top plate for connecting to the lifting device.

[0022] With this solution, the water inlet is connected to the salt pond's drain outlet, and a top plate is installed on top of the water collection cylinder to connect to the lifting device. This design ensures that the drainage box can effectively collect and drain water from the salt pond, improving drainage efficiency.

[0023] Optionally, a guide hole is provided at the bottom of the water inlet cylinder, and the guide hole on the water inlet cylinder matches the position of the guide hole on the suspension to jointly fix the plastic film.

[0024] With this solution, guide holes are provided at the bottom of the water inlet cylinder, matching the guide holes on the hook, and together they are used to secure the plastic film. This design ensures the stability and sealing of the plastic film during drainage, preventing it from shifting or being damaged during operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When drainage is required, the rope can be tightened through the rope-collecting device to make the plastic film close to the drainage box, and then the drainage box is driven down by the lifting device, so that the water in the salt pond drain outlet can enter the drainage box and be discharged from the drainage box. Multiple drainage outlets of the salt field can be drained synchronously without manual operation in sequence, which has high drainage efficiency and low labor intensity.

[0027] 2. By providing a clamping device, when the drainage box moves downward, the buoyancy of the water pushes the first and second pull rods to move, thereby driving the movable baffle to slide, so that the movable baffle and the fixed baffle clamp the plastic film. The buoyancy of the water can be used to achieve automatic clamping, which is more convenient to use.

[0028] 3. By setting up a water level sensor, the depth of the drainage box in the water can be fed back so that the height of the drainage box can be adjusted through the lifting device.

[0029] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0041] The following is combined with Figure 1-7 This application is described in further detail.

[0042] The embodiment of the present application discloses an automatic drainage device for a salt pond.

[0043] Reference Figure 1 The automatic drainage equipment of the salt pond according to the embodiment of the present invention includes: a drainage box 1, a rope collecting device 3, and a lifting device 4.

[0044] Reference Figure 1 and Figure 2 Drainage tank 1 is installed at the salt pond's drain outlet and connected to a lifting device 4 mounted on a concrete foundation. Drainage tank 1 includes a water inlet cylinder 101, a water collection cylinder 102, and a drainage pipe 104, which are connected in sequence. Water inlet cylinder 101 is provided with an opening for connecting to the salt pond's drain outlet. Water collection cylinder 102 is topped with a top plate 103 for connecting to lifting device 4. Drainage tank 1 collects and drains water from the salt pond.

[0045] Reference Figure 1 and Figure 5 The lifting device 4 is installed above the salt pond's drain outlet to raise and lower the drain tank. It includes a support frame 401 and a motorized screw 402. The lifting device is mounted on the drain outlet's concrete foundation 6 and connected to the drain tank 1 below. The motorized screw 402 controls the height of the drain tank 1, allowing it to rise and fall according to water level fluctuations.

[0046] Reference Figure 3 In one specific embodiment, a clamping device 2 is provided on the drainage box. The clamping device 2 is mounted at the bottom of the drainage box and includes a fixed baffle 201, a rubber sheet 202, a movable baffle 203, a chute 204, a slider 205, a first pull rod 206, and a buoyancy plate 207. A clamping space is formed between the fixed baffle 201 and the movable baffle 203, and the rubber sheet 202 is mounted inside the fixed and movable baffles. When the drainage box sinks into the water, the buoyancy plate 207 floats upward, driving the first pull rod 206 to push the slider 205 forward along the chute 204, causing the movable baffle 203 to move forward, causing the rubber sheet 202 to clamp the plastic film, achieving a seal.

[0047] Reference Figure 1 and Figure 4 The rope-collecting device 3 is located above the water inlet and includes a support plate 301, a hanger 302, a hanger chute 303, a diverting pulley 304, a take-up rope 305, and a lifting screw 306. The rope-collecting device tensions the plastic film, ensuring a secure seal during drainage. The lifting screw 306 pulls the take-up rope 305, which, via the diverting pulley 304, drives the hanger 302 up and down along the hanger chute 303, ensuring that the plastic film covers the water inlet cylinder 101 during drainage.

[0048] In a specific implementation, the structure and working principle of the newly added parts are further described in detail based on Example 1.

[0049] Hangers 302 are provided at each end of the tightening rope 305. Guide holes are provided at the bottom of the hangers to accommodate the plastic film wrapped around the edges of the hangers. Guide holes are also provided at the bottom of the water inlet cylinder 101. These holes align with the guide holes on the hangers 302 to secure the plastic film. Hanging chutes 303 are vertically positioned on both sides of the drainage box, and the hangers 302 slide into these chutes. This design ensures that the plastic film tightly wraps around the drainage box during tensioning, further enhancing the sealing of the equipment.

[0050] A water level sensor is installed at the bottom of the drainage box to monitor the water level in real time. According to the feedback information of the water level sensor, the electronic control system controls the height of the lifting device to keep the drainage box in the appropriate position during the drainage process.

[0051] In a specific embodiment, based on Example 2, the structures of the clamping device and the rope collecting device are further improved.

[0052] The clamping device 2 has rubber plates 202 installed on the sides where the fixed baffle 201 and the movable baffle 203 approach each other. A slider 205 is fixedly connected to the movable baffle 203 and slides within a chute 204. A first pull rod 206 is hinged at one end to the slider 205 and at the other end to a buoyancy plate 207. A second pull rod has one end fixed within the chute 204 and at the other end hinged to the buoyancy plate 207. When the drainage tank 1 sinks into the water, the buoyancy plate 207 rises, generating thrust. This thrust, driven by the first and second pull rods, moves the slider 205, pushing the movable baffle 203 to clamp the plastic film, achieving automatic clamping and sealing.

[0053] A lifting screw 306 connects to a take-up rope 305, pulling the hanger 302 up and down along the hanger chute 303, ensuring that the plastic film covers the water inlet cylinder 101 during drainage. A diverting pulley 304 is fixed to the side of the hanger chute 303. The take-up rope 305 passes over the pulley and connects to the lifting screw 306. The design of the diverting pulley ensures that the take-up rope is evenly stressed, preventing deviation and wrinkles when the plastic film is tightened.

[0054] Reference Figure 6 and Figure 7 The salt pond automatic drainage equipment has two working postures: thatch posture and drainage posture.

[0055] In the plastic thatch position, the guide hole of the hanging 304 is at the same horizontal plane as the guide hole of the water inlet cylinder 101. During the salt pond film covering process, the film edge hanging rope drives the film forward along the guide hole. After the film covering construction is completed, the automatic drainage device changes to the drainage position.

[0056] In the drainage position, the lifting screw 306 pulls the tightening rope 305, causing the hanger 302 to rise along the hanging chute 303. The plastic film lifted by the hanger 302 covers the water inlet cylinder 101. The electric screw lifting device 402 presses the water inlet cylinder 101 downward to the surface of the accumulated water. During the downward pressure, the buoyancy plate 207 floats, causing the pull rod 206 to generate thrust, pushing the movable baffle 203. The rubber plates 202 on the surfaces of the fixed baffle 201 and the movable baffle 203 are tightly attached, clamping the plastic film and achieving closed drainage.

[0057] In summary, the present invention, through its automated and intelligent design, effectively solves the manual operation problems of the prior art, improves drainage efficiency, reduces labor intensity, ensures the safety of workers, and has broad application prospects. The present invention has a simple structure, low cost, high reliability, and can adapt to different salt pond drainage requirements, thus possessing high practical value.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
