Description

Technical Field

[0001] This utility model relates to the field of valve well technology, specifically to a solar-powered automatic pumping device for draining accumulated water in valve wells. Background Technology

[0002] Valve wells are underground structures specifically designed for the installation and protection of valves and related control equipment in underground pipeline systems such as gas, water supply, drainage, and heating pipelines, and for providing operating space for maintenance personnel.

[0003] In existing technologies, some gas valve wells are flooded for extended periods due to low surrounding water levels and rain, causing the valves to be submerged for long periods. This leads to corrosion of steel valves, affecting their lifespan and operation, making them difficult to operate. The consequences are particularly severe when valve operation is difficult during various operations and emergency rescues. Therefore, a solar-powered automatic water pumping device for valve wells is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide an automatic pumping device for water accumulation in solar-powered valve wells to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic pumping device for water accumulation in a solar-powered valve well, comprising a valve well and a support frame; an installation frame is installed on the inner wall of the valve well, a conveying pipe is installed on the installation frame, a suction structure is connected to the conveying pipe, an adjustment plate is connected to the suction structure, a lifting adjustment structure is connected to the adjustment plate, a filter sleeve is connected to the suction structure, and an anti-clogging structure is connected to the filter sleeve.

[0006] Preferably, the suction structure includes a suction pump, the suction end of which is installed on the delivery pipe, the discharge end of which is installed on the discharge pipe, one end of which is installed on the delivery pipe and the other end of which is installed on the suction pipe, the suction pipe being located inside the valve well.

[0007] Preferably, a solar panel, a lithium battery, and a control panel are installed on the support frame. A fixing plate is fixedly fitted onto the suction pipe. A dual float level switch is installed below the fixing plate. An upper float and a lower float are slidably installed on the dual float level switch. The suction pump, solar panel, lithium battery, control panel, and dual float level switch are electrically connected by wires.

[0008] Preferably, the lifting and adjusting structure includes a rod, one end of which is fitted with a connecting plate. The adjusting plate has several holes inside, and the rod is inserted into the corresponding hole. The adjusting plate is installed above the fixed plate.

[0009] Preferably, a spring is installed between the mounting bracket and the connecting plate, and the spring is slidably sleeved on the insertion rod.

[0010] Preferably, the mounting bracket has a sliding hole inside, and the adjusting plate is slidably installed inside the sliding hole.

[0011] Preferably, the anti-clogging structure includes a motor, which is mounted on a mounting bracket. The motor is electrically connected to the control panel via a wire. A connecting rod is installed at the output end of the motor. The connecting rod is rotatably installed inside the delivery pipe. A slide rod is slidably installed inside the connecting rod. The slide rod is rotatably installed inside the filter sleeve. The filter sleeve is installed at one end of the suction pipe. An L-shaped scraper is installed at one end of the slide rod. The L-shaped scraper is in contact with the outer surface of the filter sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This solar-powered automatic water drainage device for valve wells activates a suction pump when the water level in the valve well exceeds the height of the upper float. The pump uses a delivery pipe, corrugated pipe, and suction pipe to draw water from the valve well and discharge it to the outside. The pump continues until the water level in the valve well is below the height of the lower float, causing the lower float to descend. The suction pump is then shut off via the control panel. This prevents prolonged water accumulation in the valve well and avoids accelerated corrosion caused by prolonged submersion of the valve. The delivery pipe, corrugated pipe, suction pipe, and dual float level switch are all powered by lithium batteries, which can be charged using solar panels, resulting in greater energy savings, extended valve lifespan, and ensuring the valve remains operable and maintainable. This reduces labor, machinery, maintenance, and time costs, while improving work efficiency.

[0014] Pulling the lever releases the restriction on the adjustment plate, and pulling the adjustment plate adjusts the height of the suction pipe and the double float level switch to adjust according to the height of the valve well. During the suction process, the filter sleeve can be used to intercept impurities and prevent them from clogging the suction pipe. At the same time, turning on the motor controls the L-shaped scraper to scrape the surface of the filter sleeve to prevent the holes in the filter sleeve from becoming blocked.

Detailed Implementation

[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] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: an automatic pumping device for water accumulation in a solar-powered valve well, comprising a valve well 100 and a support frame 101; an installation frame 200 is installed on the inner wall of the valve well 100, a conveying pipe 201 is installed on the installation frame 200, a suction structure is connected to the conveying pipe 201, the suction structure is used to pump water accumulation in the valve well 100, an adjusting plate 300 is connected to the suction structure, a lifting adjusting structure is connected to the adjusting plate 300, the lifting adjusting structure is used to adjust the height of the suction structure according to the depth of the valve well, a filter sleeve 400 is connected to the suction structure, and an anti-clogging structure is connected to the filter sleeve 400, the anti-clogging structure is used to prevent debris from clogging the suction structure during pumping.

[0024] Furthermore, the suction structure includes a suction pump 202, the suction end of which is installed on the delivery pipe 201, and the discharge end of the suction pump 202 is installed with a discharge pipe 203. One end of the bellows 204 is installed on the delivery pipe 201, and the other end of the bellows 204 is installed with a suction pipe 205. The suction pipe 205 is located inside the valve well 100. When the suction pump 202 is turned on, it will use the delivery pipe 201, the bellows 204 and the suction pipe 205 to draw water from the valve well 100 and discharge it to the outside through the suction pump 202.

[0025] Furthermore, a solar panel 206, a lithium battery 207, and a control panel 208 are installed on the support frame 101. A fixing plate 209 is fixedly sleeved on the suction pipe 205. A dual float level switch 210 is installed below the fixing plate 209. An upper float 211 and a lower float 212 are slidably installed on the dual float level switch 210. The suction pump 202, solar panel 206, lithium battery 207, control panel 208, and dual float level switch 210 are electrically connected by wires. When the water level rises continuously and causes the upper float 211 to rise, a signal is sent to the control panel 208 to control the suction pump 202 to start. When the water level drops and causes the lower float 212 to drop, a signal is sent to the control panel 208 to control the suction pump 202 to stop. The suction pump 202, control panel 208, and dual float level switch 210 can all be powered by the lithium battery 207, and the lithium battery 207 can be charged by the solar panel 206.

[0026] Furthermore, the lifting and adjusting structure includes a rod 301, with a connecting plate 303 installed at one end of the rod 301. The adjusting plate 300 has several holes 302 inside, and the rod 301 is inserted into the corresponding hole 302. The adjusting plate 300 is installed above the fixed plate 209. Pulling the connecting plate 303 can cause the rod 301 to disengage from the corresponding hole 302, thus releasing the restriction on the adjusting plate 300. Then, vertically pulling the adjusting plate 300 can cause the fixed plate 209, the suction pipe 205, and the double float level switch 210 to rise and fall, so as to finely adjust the height of the suction pipe 205 and the double float level switch 210 according to the depth of the valve well 100 and the height of the valve stem in the valve well 100.

[0027] Furthermore, a spring 304 is installed between the mounting bracket 200 and the connecting plate 303. The spring 304 is slidably sleeved on the insertion rod 301. Pulling the connecting plate 303 can stretch the spring 304. When the connecting plate 303 is released, the stretched spring 304 will contract and drive the connecting plate 303 to move and reset.

[0028] Furthermore, the mounting bracket 200 has a sliding hole 305 inside, and the adjusting plate 300 is slidably installed inside the sliding hole 305. Pulling the adjusting plate 300 can make it slide inside the sliding hole 305. The sliding hole 305 can limit the movement direction of the adjusting plate 300.

[0029] Example 2: As Figure 3-6 To prevent clogging of the filter sleeve 400 during water suction, an anti-clogging structure is implemented. This structure includes a motor 401, which is mounted on the mounting bracket 200. The motor 401 is electrically connected to the control panel 208 via a wire. A connecting rod 402 is mounted on the output end of the motor 401. The connecting rod 402 is rotatably mounted inside the delivery pipe 201. A sliding rod 403 is slidably mounted inside the connecting rod 402, and the sliding rod 403 is rotatably mounted inside the filter sleeve 400. The filter sleeve 400 is installed at one end of the suction pipe 205, and an L-shaped scraper 404 is installed at one end of the slide rod 403. The L-shaped scraper 404 contacts the outer surface of the filter sleeve 400. The filter sleeve 400 can be used to intercept impurities in the accumulated water to avoid clogging of the suction pipe 205. The motor 401 is turned on to control the connecting rod 402 and the slide rod 403 to rotate, which drives the L-shaped scraper 404 to scrape the surface of the filter sleeve 400 to prevent impurities from adhering to the surface of the filter sleeve 400. The remaining features are the same as in Embodiment 1.

[0030] The working principle is as follows: When water accumulates in the valve well 100, the rising water level will cause the lower float 212 and the upper float 211 to float upwards. Based on existing technology, the dual float level switch 210 is a level control device based on buoyancy drive and mechanical / magnetic linkage. When the water level rises and causes the upper float 211 to rise, a signal is sent to the control panel 208 to control the suction pump 202 to start. Conversely, when the water level drops and causes the lower float 212 to fall, a signal is sent to the control panel 208 to control suction. Pump 202 is turned off, so that when the water level in valve well 100 rises above the height of the upper float 211, suction pump 202 will be turned on. When suction pump 202 is turned on, it will use delivery pipe 201, corrugated pipe 204 and suction pipe 205 to draw water from valve well 100 and discharge it to the outside through suction pump 202. Delivery pipe 201 can be buried underground until the water level in valve well 100 is lower than the height of lower float 212, so that lower float 212 will drop and suction pump 202 will be turned off by control panel 208.

[0031] During the process of pumping out accumulated water, the filter sleeve 400 can be used to intercept impurities in the water, preventing blockage of the suction pipe 205. Simultaneously, the motor 401 can be activated to control the rotation of the connecting rod 402 and the sliding rod 403. The sliding rod 403 can drive the L-shaped scraper 404 to scrape the surface of the filter sleeve 400, preventing impurities from adhering to the surface of the filter sleeve 400 and causing blockage of the pores. Furthermore, pulling the connecting plate 303 stretches the spring 304 and causes the insertion rod 301 to disengage from the corresponding insertion hole 302, thus releasing the restriction on the adjusting plate 300. Then, vertically pulling the adjusting plate 300 allows it to slide within the sliding hole 305. Simultaneously, the adjusting plate 300 drives the fixed plate 209 to move up and down, which in turn drives the suction pipe 205 and the dual float level switch 210 to move up and down. This allows for fine-tuning of the height of the suction pipe 205 and the dual float level switch 210 based on the depth of the valve well 100 and the height of the valve stem within the valve well 100. During the adjustment of the suction pipe 205, the bellows 204 will extend and retract to adapt, and the slide rod 403 will slide within the connecting rod 402. After adjustment, the connecting plate 303 will be released, at which point the stretched spring 304 will contract and move the connecting plate 303 back to its original position, causing the connecting plate 303 to re-insert the insertion rod 301 into the corresponding insertion hole 302, thus fixing the height of the adjusting plate 300. The motor 401, suction pump 202, control panel 208, and dual float level switch 210 can all be powered by the lithium battery 207, and the lithium battery 207 can be charged using the solar panel 206.
