Description

Technical Field

[0001] This utility model relates to the field of public health and epidemic prevention equipment technology, specifically an electric recyclable spraying device for mosquito control on the inner wall of a sewer well. Background Technology

[0002] Mosquitoes are important vectors for many bacteria and viruses, and regular mosquito control is a crucial part of public health management. The damp, dark, and often stagnant internal environments of urban sewage wells and storm drains provide ideal habitats for mosquitoes to gather, breed, and inhabit. Their eggs and larvae often attach to the inner walls of these pipes. These manhole covers, usually made of cast metal, are highly susceptible to corrosion and deformation from prolonged exposure to rainwater and sewage, rendering many manhole covers unable to be opened properly. This severely hinders the effective implementation of conventional pest control methods, creating blind spots in mosquito control and continuously increasing the risk of vector-borne disease transmission, posing a significant challenge to urban pest management and public health safety. Utility Model Content

[0003] To address the technical problem in the background art where the inability of the manhole cover to be opened properly affects mosquito control, this utility model provides an electric recyclable spraying device for mosquito control on the inner wall of a sewer well.

[0004] The technical solution of this utility model is as follows: An electric recyclable spraying device for mosquito control on the inner wall of a sewer well includes an adjustable-length stabilizing frame, a support platform above the stabilizing frame, a transmission box fixed above the support platform, and a friction transmission mechanism installed inside the transmission box. The friction transmission mechanism includes a main friction wheel and a secondary friction wheel arranged side by side. The main friction wheel is driven to rotate by a motor mounted on the outside of the transmission box through a transmission shaft, and the secondary friction wheel is rotatably connected to the inner wall of the transmission box through a rotating shaft. It also includes a transmission tube that can be inserted between the main friction wheel and the secondary friction wheel and is driven to move up and down by the friction transmission mechanism. The transmission box and the support platform have through holes in the corresponding positions. The transmission tube is a hollow tube with a nozzle connected to the bottom, and a medicine delivery tube can be inserted inside.

[0005] This equipment can extend the transmission pipe into the sewer well at a constant speed through a friction transmission mechanism to carry out mosquito and insect extermination without opening the well cover. It can also be used to apply pesticides to sewer wells with damaged covers.

[0006] Furthermore, the stabilizer is telescopic, and the transmission tube and drug delivery tube can be disassembled separately, facilitating the transportation and use of the entire equipment.

[0007] In one embodiment, the transmission box includes a rectangular box body with dimensions smaller than the upper surface dimension of the support platform, and the transmission shaft and the rotation shaft are arranged perpendicular to the side wall of the transmission box.

[0008] Since the motor is mounted on one side of the transmission box, the center of gravity will be biased to one side. To ensure the stability of the equipment during use, a counterweight is connected to the outer wall of the transmission box opposite the motor.

[0009] To facilitate the storage of the transmission tube, multiple sections of metal tubing can be used, with adjacent sections connected by threads. This avoids the problem of transporting excessively long single tubes.

[0010] Preferably, the nozzle is threaded to the bottom of the transmission tube, which allows for easy disassembly to clean clogged impurities or to replace with a different model.

[0011] Furthermore, several spray holes are arranged around the nozzle, and these spray holes are not coplanar, so as to cover a wider application area.

[0012] In one embodiment, the stabilizer is a triangular bracket, with its top end rotatably connected to the lower edge of the support platform and its bottom end rotatably connected to the base.

[0013] Furthermore, since the environment around the sewer well is generally poor and the ground is uneven, in order to ensure that the transmission pipe can enter perpendicularly to the sewer well cover, each leg of the triangular bracket is designed to be individually adjustable in length so as to adjust the equipment to a horizontal state.

[0014] Furthermore, to facilitate observation of the equipment's levelness, a leveling adjustment component is provided on the upper surface of the support platform. For example, a common round or square level can be used and embedded within the support platform.

[0015] This utility model mainly introduces a drug application device, which is used in conjunction with a medicine box. To improve on-site assembly efficiency, one end of the drug delivery pipe is movably connected to the medicine box via a quick-connect coupling.

[0016] This utility model discloses an electric recyclable spraying device for mosquito control on the inner wall of a sewer well. Its significance lies in addressing the practical pain point that mosquito control is affected when the well cover cannot be opened normally. It enables precise treatment of mosquito breeding sources through well wall-attached spraying technology without opening the well cover.

[0017] This equipment has the following significant advantages: Firstly, it can penetrate deep into the sewer pipes to achieve 360° coverage spraying, thoroughly eliminating the attachment area of ​​larvae and eggs; Secondly, the entire operation can be completed on the ground without the need for personnel to go down into the well, which greatly improves the safety of the operation; Third, it can be adapted to various drug forms, prolonging the duration of drug efficacy.

[0018] This technology effectively overcomes the limitations of existing mosquito control methods, providing an efficient and reliable solution for urban pest control and public health protection. Attached Figure Description

Detailed Implementation

[0020] See Figures 1-3 This embodiment provides an electric recyclable spraying device for mosquito control on the inner wall of a sewer well, including an adjustable length stabilizing frame, a support platform 2 above the stabilizing frame, a transmission box 3 fixed above the support platform 2, and a friction transmission mechanism 4 assembled inside the transmission box 3.

[0021] The friction transmission mechanism 4 includes a main friction wheel 41 and a secondary friction wheel 44 arranged side by side. The main friction wheel 41 is driven to rotate by a motor 43 installed on the outside of the transmission box 3 through a transmission shaft 42. The secondary friction wheel 44 is rotatably connected to the inner wall of the transmission box 3 through a rotating shaft 45.

[0022] It also includes a transmission tube 5, which can be vertically inserted between the main friction wheel 41 and the secondary friction wheel 44, and is driven to move up and down by the friction transmission mechanism 4. The transmission box 3 and the support platform 2 have through holes in corresponding positions to facilitate the movement of the transmission tube 5.

[0023] The transmission tube 5 is a hollow tube with a metal nozzle 52 connected to the bottom, and the medicine delivery tube 6 can be inserted inside.

[0024] This equipment can extend the transmission pipe 5 into the sewer well at a uniform speed through the friction transmission mechanism 4 to carry out mosquito and insect extermination work without opening the well cover 9. It can also be used to apply pesticides to sewer wells with damaged well covers 9.

[0025] Furthermore, the stabilizer is telescopic, and both the transmission tube 5 and the drug delivery tube 6 can be disassembled separately, facilitating the transportation and use of the entire equipment.

[0026] The key design features of each component will be described in detail below.

[0027] In this embodiment, the main function of the stabilizer is to support the main working component—the transmission box 3—and keep it in a horizontal position to ensure the vertical movement of the hollow tube 5.

[0028] As one implementation method, the stabilizer can be a triangular bracket 1, which is commonly used in the prior art. Its top end is rotatably connected to the lower edge of the support platform 2, and its bottom end is rotatably connected to the base.

[0029] Furthermore, since the environment around sewer wells is generally poor and the ground is often uneven, in order to ensure that the transmission pipe 5 can enter perpendicularly to the sewer cover 9, each leg of the triangular bracket 1 is designed to be individually adjustable in length to facilitate adjusting the equipment to a horizontal position. The length adjustment method can adopt the common screw lifting type.

[0030] The support platform 2 can adopt a circular structure, with its lower part hinged to the triangular bracket 1, and its upper surface is flat, which facilitates the fixing of the transmission box 3.

[0031] Furthermore, to facilitate observation of the equipment's horizontal status, a leveling component 8 is also provided on the upper surface of the support platform 2. For example, a common round or square level can be used, which is embedded in the support platform 2, see [reference needed]. Figure 2 As shown.

[0032] In one embodiment, the transmission box 3 includes a rectangular box body with a size smaller than the upper surface size of the support platform 2, and the transmission shaft 42 and the rotation shaft 45 are arranged perpendicular to the rear side wall of the transmission box 3.

[0033] Since the motor 43 is mounted on the rear side of the transmission box 3, the center of gravity will be biased to one side. To ensure the stability of the equipment during use, a counterweight 7 is connected to the outer side wall of the transmission box 3 opposite to the motor 43, i.e., the front side wall. This keeps the center of gravity of the equipment near the center of the support platform 2, ensuring stability during pesticide application.

[0034] The friction transmission mechanism 4 converts the rotational motion of the motor 43 into a linear pulling force on the transmission tube 5. Friction force is used to hold the transmission tube 5 in place. After the motor 43 is activated by the control system, the main friction wheel 41 rotates clockwise or counterclockwise, while the auxiliary friction wheel 44 rotates passively. Both mechanisms clamp the transmission tube 5 and move it upwards or downwards at a constant speed, allowing the tube to be retrieved at a constant speed, thus enabling the transmission tube 5 to pass through or exit the tool hole on the well cover 9. Simultaneously with the operation of the motor 43, the application pump or solenoid valve of the medicine tank is activated, synchronously delivering medicine to the medicine delivery pipe 6.

[0035] To facilitate the storage of the transmission tube 5, the transmission tube 5 can be made of multiple sections of metal tube 51, with adjacent metal tubes 51 connected coaxially by threads to form a rigid track, thus avoiding the problem of transporting a single tube that is too long.

[0036] Preferably, the nozzle 52 is threaded to the bottom of the transmission tube 5, which allows for easy disassembly to clean up blockages or to replace with different models.

[0037] Furthermore, several fan-shaped spray holes 521 are provided around the nozzle 52, and the several spray holes 521 are not coplanar, so as to cover a wider application area.

[0038] See Figure 3 As shown, in this embodiment, a spray hole 521 is provided around the nozzle 52 at 90-degree intervals, for a total of four spray holes 521. Two opposite spray holes 521 are located on the same horizontal line, while the two groups are located on different horizontal lines.

[0039] Although most of the tool holes on the manhole cover 9 are eccentrically positioned, under sufficient pressure, the agent sprayed from the self-flowing hole 521 is enough to reach the inner wall of the sewer well.

[0040] In this embodiment, the delivery tube 6 is a pressure-resistant flexible hose, such as a reinforced polyurethane hose, which can be inserted into the transmission tube 5 on-site. It can be inserted into the nozzle 52 so that the liquid medicine can be sprayed out of the nozzle 521 immediately after it comes out of the delivery tube 6. Moreover, the transmission tube 5 also serves to protect the flexible delivery tube 6. Of course, it is also possible to simply connect it to the upper end of the transmission tube 5 as a flexible connection between the medicine tank and the transmission tube 5.

[0041] This utility model primarily protects a pesticide application device, which is used in conjunction with existing pesticide containers; therefore, existing incorporations such as pesticide containers are not included. Figure 1 The details are shown in the drawing. For specific information, please refer to the relevant description in patent application number CN201110436013.X, entitled "A Sprayer". This application will not repeat the details.

[0042] To improve on-site assembly efficiency, the other end of the delivery pipe 6 is connected to the medicine tank via a quick-connect coupling. Under pressure, the liquid medicine in the medicine tank enters the delivery pipe 6 and is then sprayed out from the nozzle 521. In addition to liquid medicine, the medicine tank also contains foam-type disinfectant. Furthermore, the foam-type disinfectant, after being sprayed onto the inner wall of the sewer well, has a longer retention time and better disinfection effect.

[0043] This equipment features the following four innovative designs compared to other technologies; 1. Functional Integration Innovation: The linkage control of "uniform motor speed recovery" and "synchronous application of pesticides" ensures the uniformity and automation of pesticide application.

[0044] 2. Structural Innovation: The composite rod design features a "threaded hollow metal tube" with a built-in "pressure-resistant flexible hose." This balances the needs for rigid guidance and flexible drug delivery, resulting in a simple and reliable structure.

[0045] 3. Innovative dedicated actuator: The "four-way jet metal nozzle" achieves full coverage without rotation, solving the problem of limited space in the manhole cover.

[0046] 4. Adaptive Innovation: The "adjustable horizontal triangular support" ensures the stability and verticality of the equipment when operating on complex road surfaces, which is a significant improvement in practicality.
