Description

Technical Field

[0001] The utility model relates to the field of termite control, in particular to a termite control monitoring and trapping device for reservoir dams. Background Art

[0002] The harm of termites to dams is mainly reflected in nest building, swarming of winged reproductive termites, and foraging outside. When termites build nests, move between nests, swarm, and forage outside, they will dig nests and galleries in the dam. The galleries extend in all directions and intersect with each other, damaging the internal structure of the dam. When the flood level rises during the flood season and exceeds the normal water level's seepage line, water will seep into these cavities and channels hidden in the dam, causing pipe leakage inside the dam. In severe cases, landslides and dam collapses may occur, leading to floods, property losses, and accidents of human and livestock casualties. Therefore, termite control is an important matter for dam maintenance and repair.

[0003] During the operation of the dam, the trapping method is one of the commonly used termite control methods. The trapping method is to bury a termite monitoring and trapping device on the dam, and place bait (bark, wood, and fiber materials with pesticides) that termites like to eat in the termite monitoring and trapping device to trap termites. Currently, most of the termite monitoring and trapping devices on the market are cylindrical. A number of through holes are opened on the cylinder wall for termites to enter the cylinder. Bait is placed inside the cylinder to attract termites. Such termite trapping devices have the following problems in actual use:

[0004] Since the dam has a certain slope, when it rains, the underground runoff in the soil will flow down along the dam, and thus wash into the cylinder through the through holes on the cylinder wall of the trapping device buried in the soil. This will not only wash the bait, reducing the efficacy of the bait, but also easily cause water accumulation in the cylinder, leading to mildew of the bait and affecting termite feeding. In addition, rainwater will also leach the bait, causing the pesticide components in the bait to enter the water body and soil, resulting in water pollution, ecological damage, and harm to other non-target organisms. Summary of the Utility Model

[0005] The utility model aims to provide a termite control monitoring and trapping device for reservoir dams to solve the problem that the existing termite trapping device has its bait washed by the runoff in the reservoir dam when in use.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A termite prevention, monitoring and trapping device for a reservoir dam, comprising a bait cylinder, a cylinder cover and an arc-shaped baffle. A cylinder plate is provided at the top of the bait cylinder, and the cylinder cover is used to cover the cylinder plate. The top end of the baffle is detachably connected to the cylinder plate, and the bottom end of the baffle is detachably connected to the bait cylinder. A number of through holes are formed on the side wall of the bait cylinder. The circumferential length of the baffle is greater than or equal to half of the circumferential length of the bait cylinder. The baffle is used to be installed on the bait cylinder to block the through holes. A number of protrusions for supporting the baffle are provided on the area of the outer wall of the bait cylinder blocked by the baffle. When the bait cylinder is buried in the dam, the side with the baffle faces the top of the dam.

[0008] Preferably, as an improvement, it further comprises a bait seat, which includes a tray and a handle. The handle is vertically arranged on the tray, and a number of fan-shaped holes are formed on the tray.

[0009] Preferably, as an improvement, the bottom of the bait cylinder is conical and a drain hole is opened at the bottom of the conical part. When the bait seat is placed in the bait cylinder, the tray is supported on the top of the conical part.

[0010] Preferably, as an improvement, a number of drain holes are formed on the conical part, and the drain holes are arranged on the side far from the baffle.

[0011] Preferably, as an improvement, a plastic clamping protrusion is fixed at the top of the baffle, a jack is opened at the bottom of the baffle, a clamping hole for clamping the clamping protrusion is opened on the cylinder plate, and a plastic inserting rod capable of being clamped in the jack is fixed on the outer wall of the bottom of the bait cylinder. The baffle is detachably installed on the bait cylinder through the clamping protrusion and the jack.

[0012] Preferably, as an improvement, the bottom end of the baffle is 1-2 cm longer than the bait cylinder.

[0013] Preferably, as an improvement, the length of the protrusion is 3-8 mm.

[0014] Preferably, as an improvement, the through holes are vertical strip-shaped holes, the through holes are evenly distributed on the bait cylinder, and the number of the through holes is 8.

[0015] The principle and beneficial effects of this solution are as follows:

[0016] 1. Since rainwater flows downward along the top of the dam during rain, an arc-shaped baffle is provided on the bait cylinder in this solution to block the through holes on the side of the bait cylinder facing the top of the dam, which can effectively block rainwater, effectively avoid rainwater from washing and leaching the bait in the bait cylinder, avoid the bait in the bait cylinder from getting mildewed due to water accumulation, and can also avoid the chemical components in the bait from being washed into the soil and water body, causing water pollution, ecological damage and harm to non-target organisms. The circumferential length of the baffle being greater than or equal to half of the circumferential length of the bait cylinder can block the rainwater flowing down from the top of the dam as much as possible, and the water blocking effect is good.

[0017] 2. A protrusion is provided on the bait cartridge. On the one hand, it can form a passage for termites to enter and exit between the baffle and the bait cartridge, without affecting the entry and exit of termites into the bait cartridge. On the other hand, the protrusion can also support the baffle, preventing the baffle from being deformed by the impact of rainwater and soil, and also preventing the baffle from deforming and pressing the passage for termites to enter and exit. In this solution, setting the length of the protrusion to 3 - 8 mm can achieve good comprehensive effects. If it is less than 3 mm, the passage is too small for termites to enter and exit conveniently. If it is greater than 8 mm, the passage is too large, and the distance between the part of the baffle not supported by the protrusion and the bait cartridge is too large, making it easier to deform.

[0018] 3. The bait seat is used to place in the bait cartridge to hold the bait. The bait is generally bark, wood, and fiber materials with medicine. The tray is used to hold the bait, and the handle facilitates taking out the bait seat from the bait cartridge. In this solution, several fan-shaped holes are provided on the tray to facilitate water leakage. Even if a small amount of water in the soil enters the bait cartridge by infiltration, it cannot accumulate on the tray, effectively avoiding bait waterlogging.

[0019] On this basis, in this solution, the bottom of the bait cartridge is set to be conical, so that after the bait seat is placed, it can be placed on the top of the conical part, making the conical part hollow. Coupled with a drain hole opened at the bottom of the conical part, even if there is a small amount of infiltrated water at the bottom of the bait cartridge, it can be collected at the bottom under the action of the cone and discharged from the drain hole, accelerating drainage and avoiding waterlogging. At the same time, the tray being suspended on the top of the conical part can also prevent the bait from being soaked in water.

[0020] Furthermore, in this solution, drain holes are additionally opened in the part of the conical part not blocked by the baffle, which can further accelerate the drainage effect. The drain holes are set on the side not blocked by the baffle, that is, facing the bottom of the dam of the dike, so that the infiltrated water in the bait cartridge can flow downwards and be discharged from the bait cartridge faster, with good drainage effect. At the same time, this also increases the chance for termites to discover the bait and adds a passage for termites to enter and exit the bait cartridge.

[0021] 4. In this solution, by snapping the plastic convex on the top of the baffle into the card hole on the cartridge tray, and at the same time inserting the plastic insertion rod on the bait cartridge into the insertion hole on the baffle, the baffle can be installed on the bait cartridge. Utilizing the plastic characteristics of the plastic convex and the plastic insertion rod, applying sufficient external force can squeeze them into the card hole and the insertion hole, and they can be pulled out after applying sufficient external force. The structure is simple and the disassembly and assembly are convenient.

[0022] 5. The bottom of the baffle being 1 - 2 cm longer than the bait cartridge can better block the through holes on the bait cartridge, with better water blocking effect.

[0023] 6. Using vertical strip-shaped holes facilitates the entry of termites into the bait cartridge. The number of through holes is 8 and they are evenly distributed on the bait cartridge. Compared with a larger number of through holes, the structural strength of the bait cartridge is better. Description of the Drawings

[0029] The following is a further detailed description through specific implementation manners:

[0030] The reference numerals in the accompanying drawings of the specification include: bait cartridge 1, barrel plate 11, connection hole 12, through hole 13, conical part 14, drain port 15, drain hole 16, protrusion 17, insertion rod 18, card hole 19, baffle 2, card convex 21, bait seat 3, tray 31, handle 32, barrel cover 4, card strip 41, and strip hole 22.

[0031] Embodiment 1:

[0032] A termite control monitoring and trapping device for reservoir dams includes Figure 1 the bait cartridge 1, Figure 3 the bait seat 3, Figure 4 the barrel cover 4, and Figure 2 the arc-shaped baffle 2 shown in Figure 1 , Figure 2 and Figure 4 The bait cartridge 1, barrel cover 4, bait seat 3, and baffle 2 are all made of plastic. As shown in

[0033] A plastic clamping projection 21 is integrally formed on the top of the baffle 2. A jack is opened at the bottom of the baffle 2. A clamping hole 19 for clamping the clamping projection 21 is opened on the barrel plate 11. A plastic inserting rod 18 that can be clamped in the jack is adhesively fixed on the outer wall of the bottom of the bait cartridge 1. Relying on the plasticity of the clamping projection 21 and the inserting rod 18, the clamping projection 21 and the inserting rod 18 are respectively pressed into the clamping hole 19 and the jack with force, and the baffle 2 is detachably installed on the bait cartridge 1. The bottom end of the baffle 2 is 1-2 cm longer than the bait cartridge 1. In this embodiment, it is 1 cm. A plurality of through holes 13 are evenly opened on the side wall of the bait cartridge 1. In this embodiment, the through holes 13 are vertical strip-shaped holes, and the number of the through holes 13 is 8. The baffle 2 is used to be installed on the bait cartridge 1 to block the through holes 13. The circumferential length of the baffle 2 is greater than or equal to half of the circumferential length of the bait cartridge 1. In this embodiment, the circumferential length of the baffle 2 is selected to be equal to half of the circumferential length of the bait cartridge 1, that is, the baffle 2 blocks half of the through holes 13 on the circumference of the bait cartridge 1. A plurality of protrusions 17 for supporting the baffle 2 are adhesively fixed on the area of the outer wall of the bait cartridge 1 blocked by the baffle 2. In this embodiment, two protrusions 17 are arranged between adjacent two through holes 13, and the length of the protrusions 17 is 3-8 mm. In this embodiment, it is 5 mm.

[0034] Combined Figure 3 As shown, the bait seat 3 includes a tray 31 and a handle 32. The handle 32 is vertically adhesively fixed on the tray 31. A plurality of fan-shaped holes are opened on the tray 31. The bait seat 3 is used to put the bait cartridge 1 to hold bait. When the bait seat 3 is put into the bait cartridge 1, the handle 32 does not extend beyond the top of the bait cartridge 1, which is convenient for covering the barrel cover 4. The handle 32 is provided to facilitate taking out the tray 31 from the bait cartridge 1. The bottom of the bait cartridge 1 is conical, and a drain hole 15 is opened at the bottom of the conical part 14. When the bait seat 3 is put into the bait cartridge 1, the tray 31 is placed on the top of the conical part 14, so that the inside of the conical part 14 is hollow to prevent water accumulation. A plurality of drain holes 16 are opened on the conical part 14, and the drain holes 16 are opened on the side away from the baffle 2.

[0035] The working principle of a termite control monitoring and trapping device for reservoir dams is as follows:

[0036] The clamping projection 21 on the top of the baffle 2 is tightly clamped into the clamping hole 19 on the barrel plate 11 with force. The clamping projection 21 in this embodiment is a plastic clamping projection 21. Using the plasticity of the clamping projection 21, it can be clamped into the clamping hole 19 when a sufficient large external force is applied. Similarly, the inserting rod 18 on the bait cartridge 1 is tightly clamped into the jack on the baffle 2 with force, and thus the baffle 2 is installed on the bait cartridge 1. After the baffle 2 is installed, half of the through holes 13 on the circumference of the bait cartridge 1 are blocked, and the protrusions 17 support the baffle 2 on the inner side.

[0037] Place the bait holder 3 into the bait cylinder 1. Since the bottom of the bait cylinder 1 is conical, after the bait holder 3 is placed, the tray 31 is placed on the top of the conical part 14. The inside of the conical part 14 is hollow, thus the bottom of the bait holder 3 is suspended, preventing water from accumulating at the bottom of the bait cylinder 1. Place the bait on the tray 31, cover the cylinder cover 4, and complete the assembly of the monitoring and trapping device.

[0038] Dig a hole on the dam, vertically place the assembled monitoring and trapping device into the hole. When placing it, make the side with the baffle 2 face the top of the dam, and then bury all the parts below the cylinder tray 11 in the soil with soil. Under the attraction of the bait, termites enter the bait cylinder 1 through the through holes 13, the drain holes 15 and the drainage holes 16 to feed. Since the protrusion 17 supports the inner side of the baffle 2, there is a gap between the baffle 2 and the bait cylinder 1, forming a channel. Therefore, termites can also enter the bait cylinder 1 through the channel between the baffle 2 and the through hole 13. In case of rainy days, the rainwater in the soil flows downward along the dam. Since the baffle 2 blocks the through holes 13 on the half of the bait cylinder 1 facing the top of the dam, the rainwater cannot directly impact into the bait cylinder 1, effectively avoiding the scouring and leaching of the bait by the rainwater, thus being able to avoid water accumulation in the bait cylinder 1, mildew of the bait, and the medicine in the bait flowing into the soil and water bodies, causing environmental pollution and harm to non-target organisms. If the water vapor in the soil penetrates into the bait cylinder 1 from the unblocked through holes 13, since the tray 31 is provided with a number of fan-shaped holes and has a good water leakage effect, the water vapor will leak into the conical part 14 and be collected by the conical part 14 and discharged from the drain holes 15 and the drainage holes 16, with good drainage effect and no water accumulation in the bait cylinder 1.

[0039] Embodiment 2:

[0040] The difference between this embodiment and Embodiment 1 is that the handle 32 and the tray 31 are detachably connected. In this embodiment, the handle 32 and the tray 31 are snap-connected. The tray 31 is provided with a snap-in port, and the bottom end of the handle 32 is directly snap-connected into the snap-in port. The detachable connection between the handle 32 and the tray 31 is convenient for processing.

[0041] Embodiment 3:

[0042] As Figure 5 shown, the difference between this embodiment and Embodiment 1 is that the bottom of the baffle 2 is in a shape matching the shape of the conical part 14, that is, the bottom of the baffle 2 shrinks inward and a strip hole 22 is opened on the shrinking part. By shrinking the bottom of the baffle 2 inward, it is convenient to bury and install this solution in the soil, and at the same time, the aesthetic degree of the product is improved; in addition, a strip hole 22 is opened on the shrinking part, increasing the channels for termites to enter.
