Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a fencing device used in water conservancy projects. Background Art

[0002] Farmland water conservancy projects refer to a series of water conservancy facilities and projects built to improve agricultural production conditions and enhance farmland irrigation, drainage and flood control capabilities. After long-term use, farmland irrigation channels may experience problems such as channel wall damage, silt accumulation, and leakage, which require repair and renovation.

[0003] When the channel needs to be repaired or dredged, in order to ensure that the construction area is dry, a fencing device is needed to intercept and block the water in the channel. However, due to the inclined side walls of the channel, the existing fencing device cannot fit well with the channel, thus affecting the interception effect.

[0004] And when the construction time is long, in order not to affect the water demand of farmland, water can be pumped to other unconstructed channel parts by installing a water pump on the enclosure device. However, there are usually debris such as mud, leaves, etc. in the channel, so that the water flowing to the enclosure device carries mud, leaves and other debris. After being intercepted by the enclosure, the mud will settle and accumulate on the lower side of the enclosure, making it extremely easy for the mud to block the water pump and water pipe. Summary of the invention

[0007] Furthermore, the first filter screen is V-shaped when viewed from top to bottom, that is, it is inclined from the middle to the left rear side and the right rear side.

[0008] Furthermore, it also includes a fixing frame and a support plate; a fixing frame is fixedly connected to the backwater side of each second water baffle plate; and the support plate is connected to the fixing frame.

[0009] Furthermore, it also includes an interception plate; a plurality of interception plates are fixedly connected to the side of the second water baffle plate facing the water flow.

[0010] Furthermore, it also includes interception rods; a plurality of interception rods are fixedly connected to the first water retaining plate, and the interception rods are distributed around the filter tank.

[0011] Furthermore, a sealing strip is provided on the contact surface between the third water retaining plate and the side wall of the ditch.

[0012] Furthermore, it also includes a floating plate; the floating plate is slidably connected inside the first water baffle, the floating plate is fixedly connected to the first filter screen, and the floating plate is located inside the filter tank; a first slide groove is opened on the upper side of the filter tank; a second slide groove is opened on the lower side of the filter tank; the shapes of the first slide groove and the second slide groove match the first filter screen, and the first filter screen can slide up and down in the first slide groove and the second slide groove.

[0013] Furthermore, it also includes a fixed block and a scraper; the fixed block is fixedly connected to the first water baffle, and the fixed block is located inside the filter tank; a plurality of scrapers are fixedly connected to the left and right sides of the fixed block, and each scraper is in contact with the front surface of the first filter screen.

[0014] Furthermore, it also includes a latch and a limit block; a third slide groove is opened on the rear side of each second water baffle plate, and a notch is set at the lower part of the side of each third slide groove close to the first water baffle plate; a latch is slidably connected in each third slide groove; an L-shaped limit block is fixedly connected to the rear side of the first water baffle plate; a handle is set on the upper side of each second water baffle plate.

[0015] Furthermore, a groove is provided at the bottom of each second water retaining plate, the shape of the groove matches the shape of the support plate, and the support plate is connected to the fixing frame in a damping rotation manner.

[0016] The beneficial effects are as follows: 1. By making the bottom of the second water baffle fit the junction of the bottom and the side wall of the channel, and rotating the third water baffle to fit closely with the side wall of the channel, the enclosure device can adapt to the shape of the channel, intercept and block the water in the channel, and prevent the water from continuously flowing into the construction area, so as to ensure the dryness of the construction area. The water entering the filter tank is pumped to the unconstructed channel part by a water pump connected to the water outlet, so that the water demand of the farmland is not affected during the construction period;

[0017] Second, when water flows into the filter tank, the first filter screen intercepts and filters the debris in the water to prevent the debris in the water from clogging the water pipe connected to the water outlet. Part of the water, under the guidance of the first filter screen, drives the debris intercepted by the first filter screen to move into the storage box, and then this part of the water passes through the second filter screen and flows into the water outlet. The debris is intercepted by the second filter screen and temporarily stored in the storage box, thereby preventing the debris from adhering to the first filter screen and affecting the speed of water passing through the first filter screen.

[0018] 3. When there is a lot of highly sticky sediment attached to the first filter screen, causing the speed of water passing through the first filter screen to decrease, the amount of water entering the filter tank at this time does not reach the standard water intake of the water pump, causing the water in the filter tank to decrease rapidly. Under the action of gravity, the floating plate and the first filter screen move downward as the amount of water in the filter tank decreases, and the water flow can quickly pass through the upper part of the first filter screen in a clean state, increasing the amount of water in the filter tank, thereby driving the first filter screen to reset upward. In this process, the sediment attached to the first filter screen is scraped off by the scraper to separate it from the first filter screen, and then the separated sediment is driven by the water flow to move to the storage box for storage, thereby realizing the rapid scraping of the sediment attached to the first filter screen and effectively ensuring the water pumping capacity of the water pump to irrigate the farmland, so that the first filter screen can be quickly and automatically cleaned when it is blocked;

[0019] 4. When the water flow in the channel does not need to be blocked by the enclosure device, the latch is separated from the limit block, the fixation between the first water baffle plate and the second water baffle plate is released, and the support plate is folded down to fit the inside of the groove, and the two second water baffle plates are folded back in sequence to fold the enclosure device, so that the volume of the enclosure device is reduced, and it is convenient to carry it, so that the enclosure device can be placed in the channel or moved out of the channel without the cooperation of multiple people;

[0020] The present invention also has the following beneficial effects:

[0021] The sediment deposited in the water is intercepted by a plurality of interception plates on the front lower side of the second water retaining plate, thereby effectively reducing the amount of sediment entering the filter tank;

[0022] The interception rod is used to intercept larger debris in the water to prevent it from entering the filter tank, thereby reducing the risk of the filter tank being blocked by the debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The first filter screen 5 is V-shaped when viewed from top to bottom, that is, it is inclined from the middle to the left rear side and the right rear side.

[0041] It also includes a fixing frame 101 and a support plate 102 ; a fixing frame 101 is fixedly connected to the backwater side of each second water baffle plate 3 ; and the support plate 102 is connected to the fixing frame 101 .

[0042] It also includes an interception plate 201; a plurality of interception plates 201 are fixedly connected to the side of the second water baffle plate 3 facing the water flow.

[0043] It also includes intercepting rods 202 ; a plurality of intercepting rods 202 are fixedly connected to the first water retaining plate 1 , and the intercepting rods 202 are distributed around the filter tank 1001 .

[0044] A sealing strip is provided on the contact surface between the third water baffle plate 4 and the ditch side wall to enhance the fitting effect between the third water baffle plate 4 and the ditch side wall.

[0045] The working principle of the above embodiment is as follows:

[0046] The retaining device used in water conservancy projects will be referred to as the retaining device below.

[0047] When repairing or dredging the channel is required, in order to ensure the dryness of the construction area and prevent water flow from affecting the construction of workers, before construction, the enclosure device should be installed as follows: Figure 2 The state shown is placed in the channel, with the rear side of the enclosure device facing the construction area, the water pump is connected to the water outlet 1002 through a water pipe, and the other end of the water pipe is placed in the unconstructed channel part, and then the two second water baffles 3 are manually driven to move in the direction close to the channel side wall, so that the bottom angle of the second water baffle 3 is fitted with the corner of the channel, and the distance between the second water baffle 3 and the first water baffle 1 is increased, thereby driving the connecting airbag 2 to adaptively extend, and then the two third water baffles 4 are respectively moved to the left and right to rotate the third water baffle 4 to fit closely with the channel side wall. The third water baffle plate 4 is connected with the second water baffle plate 3 in a damping rotation manner so as not to rotate arbitrarily. The contact area between the enclosure device and the bottom of the channel is increased by the support plate 102 to enhance the stability of the enclosure device and prevent the enclosure device from tipping backwards when blocking the water flow. Moreover, a heavy object can be pressed on the support plate 102 or the enclosure device can be further fixed at the bottom of the channel by bolts as needed.

[0048] In order to ensure that other unconstructed channel parts can be irrigated normally during the construction period without affecting the water demand of farmland, when the enclosure device blocks the water flow in front of the construction area, the water pump connected to the water outlet 1002 is controlled to pump water, and the water entering the filter tank 1001 is pumped to the unconstructed channel part, so that the water demand of farmland is not affected during the construction period. However, there are usually debris such as mud, leaves, etc. in the channel, so that the water carries a large amount of mud and other debris. In order to prevent the debris in the water from clogging the water pipe connected to the water outlet 1002, when the water When flowing into the filter tank 1001, the debris in the water is intercepted and filtered by the first filter screen 5, and because the first filter screen 5 is in a V-shape, part of the water is guided by the first filter screen 5 to flow to the left rear side and the right rear side of the first filter screen 5, so that the debris intercepted by the first filter screen 5 is driven by this part of water to move into the storage box 6, and then this part of water passes through the second filter screen 7001 and flows into the water outlet 1002, and the debris is intercepted by the second filter screen 7001, and temporarily stored in the storage box 6, thereby preventing the debris from adhering to the first filter screen 5.

[0049] It should be noted that since the sediment is relatively loose and easily disturbed by water flow, when the water flow drives the sediment into the storage box 6, the water flow with a certain impact force collides with the inner wall of the storage box 6, resulting in a certain recoil force in the water flow, which makes it easy for the water flow to flush the sediment entering the storage box 6 out of the storage box 6. Therefore, the position of the second filter screen 7001 is set at the lower side of the partition plate 7, so that after the water flow enters the storage box 6, it first passes through the gap between the guide plate 6001 and the inner rear wall of the storage box 6, and then passes through the second filter screen 7001, thereby driving the sediment to move to the bottom of the guide plate 6001 through the water flow, and in this process, the upper inclined surface of the guide plate 6001 is used to promote the sediment to move backwards, and then the guide plate 6001 is used to block and separate the sediment below it, so as to prevent the recoil water flow from flushing the sediment entering the storage box 6 out of the storage box 6.

[0050] When a lot of debris is stored in the storage box 6 , the worker can pull the handle of the storage box 6 backwards to pull the storage box 6 out of the filter tank 1001 , and then clean up the debris in the storage box 6 .

[0051] According to the above working principle, we know that the present invention has the following effects:

[0052] By making the bottom of the second water baffle 3 fit the junction of the bottom and the side wall of the channel, and rotating the third water baffle 4 to fit tightly against the side wall of the channel, the enclosure device can adapt to the shape of the channel, intercept and block the water in the channel, and prevent the water from continuously flowing into the construction area, thereby ensuring the dryness of the construction area. The water entering the filter tank 1001 is pumped to the unconstructed part of the channel by a water pump connected to the water outlet 1002, so that the water demand of the farmland is not affected during the construction period.

[0053] When water flows into the filter tank 1001, the first filter screen 5 intercepts and filters the debris in the water, and part of the water flows to the left rear side and the right rear side of the first filter screen 5 under the guidance of the first filter screen 5, so that the debris intercepted by the first filter screen 5 is driven by this part of water to move into the storage box 6, and then this part of water passes through the second filter screen 7001 and flows into the water outlet 1002, and the debris is intercepted by the second filter screen 7001, and temporarily stored in the storage box 6, so as to prevent the debris from adhering to the first filter screen 5 and affecting the speed of water flowing through the first filter screen 5.

[0054] On the basis of the above technical effects, the present invention also has the following advantages:

[0055] The plurality of intercepting plates 201 on the front lower side of the second water baffle 3 can enhance the structural stability of the second water baffle 3 and intercept the sediment deposited in the water, thereby effectively reducing the amount of sediment entering the filter tank 1001 .

[0056] A plurality of intercepting rods 202 are provided on the front outer side of the filter tank 1001 , and the intercepting rods 202 are used to intercept larger debris in the water to prevent it from entering the filter tank 1001 , thereby reducing the risk of the debris clogging the filter tank 1001 .

[0057] The sealing strip provided on the contact surface between the third water baffle plate 4 and the ditch side wall effectively enhances the fitting effect between the third water baffle plate 4 and the ditch side wall, and prevents water from passing between the third water baffle plate 4 and the ditch side wall.

[0058] Example 2

[0059] On the basis of Example 1, Figure 6 and Fig.10 As shown, it also includes a floating plate 301; a floating plate 301 that moves up and down is slidably connected inside the first water baffle 1, the floating plate 301 is fixedly connected to the first filter screen 5, and the floating plate 301 is located inside the filter tank 1001; a first slide groove 1003 is opened on the upper side of the filter tank 1001; a second slide groove 1004 is opened on the lower side of the filter tank 1001; the shapes of the first slide groove 1003 and the second slide groove 1004 match the first filter screen 5, and the first filter screen 5 can slide up and down in the first slide groove 1003 and the second slide groove 1004.

[0060] It also includes a fixed block 302 and a scraper 303; the fixed block 302 is fixedly connected to the first water baffle 1, and the fixed block 302 is located inside the filter tank 1001; five equidistantly arranged scrapers 303 are fixedly connected to the left and right sides of the fixed block 302, and each scraper 303 is in contact with the front surface of the first filter screen 5.

[0061] The working principle of the above embodiment is as follows:

[0062] When the first filter screen 5 is used to intercept the debris in the water as described in Example 1:

[0063] Since the silt has a certain viscosity, the silt with strong viscosity is easy to adhere to the first filter screen 5 and cannot be driven into the storage box 6 by the water flow, which will reduce the speed of the water flow through the first filter screen 5 and even cause the first filter screen 5 to be blocked. In the initial state, when there is no silt with strong viscosity attached to the first filter screen 5, the water pump will pump out the water in the filter tank 1001, and the water can quickly pass through the first filter screen 5 into the filter tank 1001. At this time, the amount of water entering the filter tank 1001 is equal to the amount of water pumped out by the water pump, so that the water inside the filter tank 1001 is filled. Figure 6 As shown, the floating plate 301 is lifted by the water in the filter tank 1001 to be located at the upper side of the filter tank 1001 , and the upper part of the first filter screen 5 is located in the first slide groove 1003 .

[0064] When there is a lot of viscous sand attached to the first filter screen 5, the speed of water passing through the first filter screen 5 is reduced, so that after the water pump pumps the water in the filter tank 1001 away, the water cannot quickly pass through the first filter screen 5 into the filter tank 1001. At this time, the amount of water entering the filter tank 1001 does not reach the standard water intake of the water pump, so that the water in the filter tank 1001 is rapidly reduced, so that Fig.10 As shown, under the action of gravity, the float 301 and the first filter 5 move downward as the amount of water in the filter tank 1001 decreases, so that the upper part of the first filter 5 in a clean state is separated from the first chute 1003, and the lower part of the first filter 5 enters the second chute 1004, so that the water flow can quickly pass through the upper part of the first filter 5, so that the amount of water in the filter tank 1001 increases, and then drives the first filter 5 to reset upward. In this process, the first filter 5 and the scraper 303 slide relative to each other, and the scraper 303 is used to scrape the mud and sand attached to the first filter 5 to make it separate from the first filter 5, and then the water flow drives the separated mud and sand to move to the storage box 6 for storage, thereby realizing the rapid scraping of the mud and sand attached to the first filter 5, avoiding the first filter 5 from being blocked, and effectively ensuring the water pumping volume of the water pump to irrigate the farmland.

[0065] According to the above working principle, we know that the present invention has the following effects:

[0066] When there is a lot of silt with strong viscosity attached to the first filter screen 5, resulting in a decrease in the speed of water passing through the first filter screen 5, the amount of water entering the filter tank 1001 at this time does not reach the standard water intake of the water pump, so that the water in the filter tank 1001 decreases rapidly. Under the action of gravity, the floating plate 301 and the first filter screen 5 move downward as the amount of water in the filter tank 1001 decreases, so that the upper part of the first filter screen 5 in a clean state is separated from the first chute 1003, so that the water flow can quickly pass through the upper part of the first filter screen 5, so that the amount of water in the filter tank 1001 increases, and then drives the first filter screen 5 to reset upward. In this process, the silt attached to the first filter screen 5 is scraped by the scraper 303 to separate it from the first filter screen 5, and then the detached silt is driven by the water flow to move to the storage box 6 for storage, so as to achieve the rapid scraping of the silt attached to the first filter screen 5, and effectively ensure the pumping volume of the water pump, ensure the irrigation of the farmland, and achieve the rapid and automatic cleaning of the first filter screen 5 when it is blocked.

[0067] Example 3

[0068] On the basis of Example 1, Figure 2 , Figure 3 , Fig.11 and Fig.12 As shown, it also includes a latch 401 and a limit block 402; a third slide groove 3001 is provided on the rear side of each second water baffle plate 3, and a notch is provided on the lower part of each third slide groove 3001 close to the first water baffle plate 1; a latch 401 is slidably connected in each third slide groove 3001; an L-shaped limit block 402 is fixedly connected to the rear side of the first water baffle plate 1; a handle is provided on the upper side of each second water baffle plate 3.

[0069] A groove 3002 is formed at the bottom of each second water retaining plate 3 . The shape of the groove 3002 matches the shape of the support plate 102 . The support plate 102 is connected to the fixing frame 101 in a damping rotation manner.

[0070] The working principle of the above embodiment is as follows:

[0071] When the water flow in the channel is blocked by the enclosure device as described in Example 1:

[0072] Since the first water baffle plate 1 and the second water baffle plate 3 are connected by the connecting airbag 2, and since the connecting airbag 2 has a certain deformation ability, the first water baffle plate 1 is easy to move backward under the impact of the water flow. In order to ensure the stability of the enclosure device, the two latches 401 are manually pushed to slide leftward and rightward on the third slide groove 3001 respectively, so that the latch 401 moves in the direction close to the limit block 402 until the latch 401 is inserted between the limit block 402 and the second water baffle plate 3, and then the latch 401 is pushed downward to make the latch 401 stuck in the notch of the third slide groove 3001, and the latch 401 is fixed, that is, the latch 401 is Figure 4 The status shown changes to Figure 3 As shown in the state shown in the figure, the first water baffle 1 and the second water baffle 3 are fixed together by cooperating with the latch 401 and the limit block 402, thereby effectively ensuring the stability of the enclosure device. It should be noted that the extension length of the connecting airbag 2 needs to be less than the fixed length of the latch 401 to ensure that the latch 401 and the limit block 402 can normally fix the first water baffle 1 and the second water baffle 3.

[0073] When the water flow in the channel does not need to be blocked by the enclosure device, the latch 401 is reset to separate from the limit block 402, the fixation between the first water baffle plate 1 and the second water baffle plate 3 is released, and the support plate 102 is folded downward on the fixing frame 101 until the support plate 102 fits with the inside of the groove 3002, so that the support plate 102 is stored in the groove 3002. The support plate 102 is connected to the fixing frame 101 in a damped rotation connection, so that the support plate 102 will not rotate at will and disengage from the groove 3002. Fig.12 As shown, the two second water retaining plates 3 are folded backwards in sequence, and the connecting airbags 2 are adaptively bent, so that the enclosure device can be folded, the volume of the enclosure device can be reduced, and the enclosure device can be easily carried.

[0074] According to the above working principle, we know that the present invention has the following effects:

[0075] The latch 401 is inserted into the limit block 402, and the first water baffle 1 and the second water baffle 3 are fixed together through the cooperation of the latch 401 and the limit block 402, thereby effectively ensuring the stability of the enclosure device and preventing the first water baffle 1 from moving backwards under the impact of the water flow.

[0076] When there is no need to block the water flow in the channel through the enclosure device, the pin 401 is separated from the limit block 402, the fixation between the first water baffle plate 1 and the second water baffle plate 3 is released, and the support plate 102 is folded downward to fit the inside of the groove 3002, and the two second water baffle plates 3 are folded backward in sequence to fold the enclosure device, thereby reducing the volume of the enclosure device and making it easier to carry it, so that the enclosure device can be placed in the channel or moved out of the channel without the cooperation of multiple people.

[0077] On the basis of the above technical effects, the present invention also has the following advantages:
