Description

Technical Field

[0001] This invention relates to the field of termite control technology, and in particular to a green and precise control device and method for termite damage in water conservancy projects. Background Technology

[0002] Termite control in water conservancy projects is a crucial and specialized task. Termites nest inside dams, creating cavities and passageways that seriously threaten project safety, potentially leading to piping, seepage, or even dam failure. Upon discovery of termites, the following methods are commonly used for extermination: nest excavation, chemical grouting, baiting, and fumigation. Chemical grouting is one of the most frequently used and effective methods for termite control in water conservancy projects. First, the main termite tunnels are located. Then, clay slurry mixed with long-acting insecticides, under pressure, is injected into the termite nest and tunnel system using a grouting machine. This method not only kills the termites but also fills and reinforces the termite-eroded nests and passageways, thus preventing seepage and strengthening the dam.

[0003] When using a grouting machine to inject viscous grout into the nesting channels, the machine's stability is poor, making it difficult to fix the grouting head. Consequently, during operation, the grouting head, under high pressure, causes a "whipping" phenomenon, posing a safety hazard to construction workers. For example, patent application CN202411005972.X discloses a green precision treatment device and method for termite damage in water conservancy projects. This application also confirms that the grouting machine has poor stability during use. Due to different slope angles, even if the grouting machine body is stabilized, the grouting head still has the risk of falling off due to poor fixation during the grouting process.

[0004] Therefore, how to provide a green and precise control device and method for termite damage in water conservancy projects is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a green and precise treatment device and method for termite damage in water conservancy projects, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a green and precise termite control device for water conservancy projects, comprising a mobile cart, a grouting storage tank fixedly connected to the top of the mobile cart, a slurry pump installed on the back of the grouting storage tank, a grout delivery pipe fixedly connected to the output end of the slurry pump, a spray nozzle fixedly connected to the end of the grout delivery pipe away from the slurry pump, and a protective sleeve fixedly connected to the outside of the spray nozzle; further comprising:

A positioning rotating rod is installed inside the receiving slot, and a rotatable outward-expanding fixing plate is installed on the outside of the positioning rotating rod. An outward-expanding frame is located on the side of the outward-expanding fixing plate near the spray nozzle and connected to it. During operation, the electric lifting rod pushes the lifting ring plate and the lifting frame upwards, and can compress the outward-expanding frame and the outward-expanding fixing plate through the connecting arm, causing the outward-expanding fixing plate to rotate on the positioning rotating rod; It also includes:

[0009] A shrinking spring is located at the top of the outer expansion fixed plate. A movable plate and an auxiliary extension plate are sequentially arranged at the bottom of the shrinking spring. A pressing force frame and a pressing roller are arranged on the top of the movable plate near the spray head.

[0010] An expansion base, located outside the shotcrete head, allows the extrusion roller to rotate with the expansion base and compress the shotcrete as the expansion fixing plate rotates; it also includes:

[0011] An inflatable airbag is located at the bottom inner side of the outward expansion fixing plate.

[0012] An air pump is installed on the outside of the grout storage tank. The air pump is connected to the air bladder and can inflate and de-inflate the air bladder.

[0013] Furthermore, it also includes a drive assembly, which consists of a fixed circular plate, an electric lifting rod, a lifting ring plate, a lifting frame, a connecting arm, an outer expansion frame, an outer expansion fixing plate, a storage slot, and a positioning rotating rod;

[0014] The fixed circular plate is fixedly connected to the outside of the spray head near the bottom. The electric lifting rod is fixedly connected to the left and right sides of the bottom of the fixed circular plate. The electric lifting rod has a telescopic end. The lifting ring plate is fixedly connected to the telescopic end of the electric lifting rod. The lifting frame is fixedly connected to the top outside of the lifting ring plate. The connecting arm is rotatably connected to the middle of the lifting frame. The outward expansion frame is rotatably connected to the side of the connecting arm away from the lifting frame. The outward expansion fixing plate is fixedly connected to the outside of the outward expansion frame. The storage slot is opened at the bottom outside of the protective sleeve.

When the electric lifting rod is working, it can control the lifting ring plate and the lifting frame to rise and squeeze the connecting arm.

[0015] Furthermore, it also includes a moving assembly, which consists of a retraction spring, a moving plate, an auxiliary extension plate, a pressing force frame, a pressing roller, and an outward expansion base;

The contraction spring can support the movable plate and the auxiliary extension plate.

[0017] Furthermore, it also includes a stabilizing component, which consists of a support plate, an air pump, a connecting pipe, a diversion pipe frame, and an inflatable bladder;

[0018] The support plate is fixedly connected to the rear right side of the grouting storage tank. The air pump is fixedly connected to the top of the support plate. The air pump has an output port. The connecting pipe is fixedly connected to the air pump output port. The diversion pipe frame is fixedly connected to the outside of the grouting pipeline and is located near the grouting head. The air bladder is fixedly connected to the side of the outward expansion fixing plate near the protective sleeve. The air bladder can be inflated and expands on the side of the outward expansion fixing plate.

[0019] Furthermore, the outer side of the expansion fixing plate is provided with transverse ribs, the bottom of the expansion fixing plate is provided with an inlet / outlet groove to accommodate the movement of the auxiliary extension plate, and the auxiliary extension plate is provided with vertical ribs on the side away from the spray head, so that the auxiliary extension plate can move at the bottom of the expansion fixing plate.

[0020] Furthermore, the top of the outer expansion fixing plate near the spray head is provided with a limiting groove to accommodate the movement of the movable plate. The movable plate near the spray head passes through the limiting groove and extends into the protective sleeve, allowing the movable plate to move inside the outer expansion fixing plate.

[0021] Furthermore, a connecting pipe is fixedly connected to the bottom of the diversion tube frame. The connecting pipe passes through the protective sleeve and the outer expansion base from top to bottom and extends to the lower side of the outer expansion base to be fixedly connected to the airbag. The airbag and the outer expansion frame are staggered, and a groove is provided in the middle of the airbag. The groove can prevent motion interference when the connecting arm moves inside the protective sleeve.

[0022] Furthermore, the outer diameter of the expanded base gradually increases from top to bottom, and the top of the outer side of the expanded base is set as an arc surface, so that the extrusion roller can move on the arc surface of the expanded base when it contacts the expanded base.

[0023] A green and precise method for controlling termite damage in water conservancy projects includes the following steps:

[0024] Clay slurry mixed with long-acting insecticides is poured into the grouting storage tank;

[0025] Insert a protective sleeve into the main termite tunnel of the termite nest, and at the same time, insert the spray nozzle inside the protective sleeve into the main termite tunnel.

[0026] Control the operation of the electric lifting boom, so that when the electric lifting boom is working, the outer expansion fixing plate expands underground and the protective sleeve is fixed.

[0027] Control the operation of the mud pump so that it can pressurize and spray clay slurry into the termite nest through the slurry delivery pipe and spray nozzle. The clay slurry quickly fills the termite nest, and after the clay slurry dries, it reinforces the ground.

[0028] The beneficial effects of this invention are:

[0029] 1. In this invention, in moist and soft soil, the soil is squeezed by an outwardly expanding fixing plate to form a cavity, and then an inflatable bladder is used to expand and fill it, forming a dual fixing mechanism of mechanical squeezing and pneumatic filling. This can effectively resist the huge reverse force generated when the spraying head is working, prevent the spraying head from loosening or falling out, and fundamentally ensure the operational stability under unfavorable geological conditions.

[0030] 2. In dry, hard soil, by rotating the outward-expanding fixing plate to a vertical state and automatically popping out an auxiliary extension plate with vertical ribs, a single fixing point is transformed into a stable structure with a larger cross-sectional area and crisscrossing ribs. This allows the shotcrete head to withstand forces from all directions during shotcreting, achieving an extremely firm fixing effect even in hard soil.

[0031] 3. In this invention, the outer expansion fixing plate opens in a ring on the outside of the protective sleeve, which is equivalent to forming a temporary baffle above the grouting point. This can effectively prevent the clay grout from flowing upward or around under pressure, forcing the grout to fill the main termite tunnel of the termite nest in the downward and horizontal direction first. This ensures that the grout can effectively reach the depth of the nest, avoids the grout from accumulating ineffectively at the entrance, and improves the filling efficiency and thoroughness of grouting.

[0032] 4. After the work is completed, the airbag is deflated by controlling the air pump, and the electric rod is lowered and the outer expansion fixing plate is retracted, which can restore the smoothness of the outer side of the protective sleeve. This allows the protective sleeve to be easily and smoothly removed from the solidified grout and soil, avoiding the damage that may be caused to the surrounding grouting area by forcibly pulling it out, and making it convenient for the next use.

[0033] 5. This invention can define and guide the grouting area, avoiding large-scale damage to the soil around the nest and ineffective diffusion of grout, and minimizing interference with the aquatic ecosystem. This is particularly important for the environmental protection around water conservancy facilities and is in line with the goal of green and precise governance. Attached Figure Description

[0056] Example 3

[0057] refer to Figure 2 and Figure 9 Based on Embodiment 2, the present invention provides a technical solution that further includes a stabilizing component 9, which consists of a support plate 901, an air pump 902, a connecting pipe 903, a diversion pipe frame 904, and an inflatable bladder 905.

[0058] The support plate 901 is fixedly connected to the rear right side of the grouting storage tank 2. The air pump 902 is fixedly connected to the top of the support plate 901. The air pump 902 has an output port. The connecting pipe 903 is fixedly connected to the output port of the air pump 902. The diversion pipe rack 904 is fixedly connected to the outside of the grouting pipe 4 and is located near the end of the spray nozzle 5. The air bladder 905 is fixedly connected to the side of the outward expansion fixing plate 707 near the protective sleeve 6.

The airbag 905 and the outer expansion frame 706 are staggered, and a groove is provided in the middle of the airbag 905. The groove can prevent the connecting arm 705 from moving inside the protective sleeve 6 and causing motion interference.

[0060] A green and precise method for controlling termite damage in water conservancy projects includes the following steps:

[0061] Add the clay slurry mixed with long-acting insecticide into the grouting storage tank 2;

[0062] Insert a protective sleeve 6 into the main termite tunnel of the termite nest, and at the same time, the spray nozzle 5 inside the protective sleeve 6 is inserted into the main termite tunnel.

[0063] Control the operation of the electric lifting pole 702 so that when the electric lifting pole 702 is working, it expands the outer fixing plate 707 underground and fixes the protective sleeve 6.

[0064] Control the operation of the mud pump 3 so that when the mud pump 3 is working, it can pressurize and spray clay slurry into the termite nest through the slurry delivery pipe 4 and the spray nozzle 5. The clay slurry quickly fills the termite nest, and after the clay slurry dries, it reinforces the ground.

[0065] A fixed circular plate 701 is set on the outside of the spray head 5 near the bottom. Electric lifting rods 702 are set on the left and right sides of the bottom of the fixed circular plate 701. A lifting ring plate 703 is set on the top of the fixed circular plate 701. A lifting frame 704 is set on the top of the lifting ring plate 703. A connecting arm 705 is set in the middle of the lifting frame 704. The lifting frame 704 is connected to the outer expansion frame 706 through the connecting arm 705.

[0066] A storage slot 708 is provided on the outside of the protective sleeve 6. A positioning rotating rod 709 is provided inside the storage slot 708. A rotatable outwardly expanding fixing plate 707 is provided on the outside of the positioning rotating rod 709. An outwardly expanding frame 706 is provided on the side of the outwardly expanding fixing plate 707 near the shotcrete head 5 and is connected to it. When working, the electric lifting rod 702 pushes the lifting ring plate 703 and the lifting frame 704 to rise. It can squeeze the outwardly expanding frame 706 and the outwardly expanding fixing plate 707 through the connecting arm 705, so that the outwardly expanding fixing plate 707 rotates on the positioning rotating rod 709; it also includes:

[0067] A retraction spring 801 is located at the top of the outer expansion fixing plate 707. A movable plate 802 and an auxiliary extension plate 803 are sequentially arranged at the bottom of the retraction spring 801. A pressing force frame 804 and a pressing roller 805 are arranged on the top of the movable plate 802 near the spray head 5.

[0068] An expansion base 806 is disposed outside the shotcrete head 5. When the expansion fixing plate 707 rotates, the extrusion roller 805 can rotate with the expansion fixing plate 707 and extrude pressure from the expansion base 806; it also includes:

[0069] Inflatable bladder 905, which is located at the bottom inner side of the outward expansion fixing plate 707;

[0070] An air pump 902 is located on the outside of the grouting storage tank 2. The air pump 902 is connected to the air bladder 905 and can inflate and de-inflate the air bladder 905.

[0071] When grouting is required in the main termite tunnel of a termite nest, the protective sleeve 6 is inserted into the main termite tunnel. Since water conservancy facilities are generally located near water, some soil is relatively moist and soft, while other parts are dry and hard. When the protective sleeve 6 is inserted into the main termite tunnel, and the surrounding soil is moist and soft, the electric lifting rod 702 is operated. When the electric lifting rod 702 operates, it causes the lifting ring plate 703 to rise, and the lifting frame 704 on the lifting ring plate 703 to press against the connecting arm 705. This causes the outer expansion frame 706 on the other side of the connecting arm 705 to bear force. Simultaneously, when the outer expansion frame 706 is under force, it causes the outer expansion fixing plate 707 to... The positioning rod 709 on the outside of the protective sleeve 6 rotates, and the outer expansion fixing plate 707 squeezes the moist soil on the outside of the protective sleeve 6, forming a partial cavity at the bottom. Then, the air pump 902 is started. When the air pump 902 is working, it can send high pressure into the air bladder 905 through the connecting pipe 903 and the diversion pipe frame 904, causing the air bladder 905 to expand and fill the cavity. The reverse force when the grouting head 5 sprays out clay slurry cooperates with the air bladder 905 through the outer expansion fixing plate 707, so that the protective sleeve 6 can be fixed in the soil, preventing the grouting head 5 from shaking and falling out of the soil in the moist soil, and ensuring the stability of grouting in the moist soil environment.

[0072] By controlling the operation of the electric lifting rod 702, the outer expansion fixing plate 707 can be opened in a ring outside the protective sleeve 6. When grouting the main tunnel of the termite nest, it can effectively prevent the grout from flowing upward and can limit the direction of the clay slurry during grouting, so that it can be poured downward as much as possible, thus ensuring the grouting effect of the main tunnel of the termite nest.

[0073] When the protective sleeve 6 needs to be inserted into the main termite tunnel of the termite nest, and the surrounding soil is relatively dry and hard, the electric lifting rod 702 is controlled to move to its maximum stroke. At this time, the lifting ring plate 703 and the lifting frame 704 rise and press against the connecting arm 705, increasing the height and allowing the outer expansion fixing plate 707 to rotate on the positioning rotating rod 709. The outer expansion fixing plate 707 rotates to a position perpendicular to the outer wall of the protective sleeve 6. During the rotation of the outer expansion fixing plate 707, the squeezing roller 805 on the inner side of the outer expansion fixing plate 707 can rotate synchronously, so that the squeezing roller 805 contacts the outer expansion base 806 on the outside of the spray head 5 when it rotates, and the outer expansion base 806 is outside the squeezing roller 805. The outer expansion fixing plate 707 slides to the side. When the outer expansion fixing plate 707 rotates to be perpendicular to the outer side of the protective sleeve 6, the extrusion roller 805 is extruded by the outer expansion base 806. This allows the extrusion roller 805 to drive the contraction spring 801 to stretch through the extrusion force frame 804 and the moving plate 802. At the same time, when the contraction spring 801 is stretched inside the outer expansion fixing plate 707, the auxiliary extension plate 803 protrudes from inside the outer expansion fixing plate 707 to the outside, increasing the cross-sectional area at the outer expansion fixing plate 707. Since the outer expansion fixing plate 707 is provided with transverse ribs and the auxiliary extension plate 803 is provided with vertical ribs, the protective sleeve 6 can withstand the vertical and horizontal forces when it shakes, thus enabling the protective sleeve 6 to be effectively fixed even in hard soil.

[0074] When it is necessary to remove the protective sleeve 6, the air pump 902 is controlled to work to extract the air from the air bladder 905, which can deflate the air bladder 905. Then, the electric lifting rod 702 is controlled to work to lower the lifting ring plate 703, which allows the outer expansion fixing plate 707 to rotate on the positioning rotating rod 709 into the storage groove 708 on the protective sleeve 6, so that the outer side of the protective sleeve 6 forms a smooth surface. At this time, the outer expansion fixing plate 707 used to fix the protective sleeve 6 to the soil cannot provide effective support, so the protective sleeve 6 can be directly pulled out from the main termite tunnel of the termite nest.

[0075] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
