Technical Field
[0001] The present invention relates to the technical field of chemical pumps, and particularly to a transmission device and a chemical pump. Background Art
[0002] There are various types of chemical pumps, including stainless steel chemical pumps, plastic chemical pumps, fluoroplastic chemical pumps, electric chemical pumps, pneumatic chemical pumps, etc. They are widely used in industries, urban water supply and drainage, as well as farmland and orchard irrigation and drainage fields, and are mainly used for transporting clear water or other liquids with physical and chemical properties similar to clear water. Chemical pumps are usually driven by motors, and the working efficiency of the motors is affected by their own temperature changes.
[0003] A transmission device is provided in the chemical pump for outputting power. A Chinese patent with the publication number CN112943909B discloses a lubrication device, which includes an oil collecting component and an oil throwing member. The oil collecting component is formed with an oil guiding channel. The oil throwing member is connected to the transmission shaft of the gearbox. The oil throwing member rotates with the transmission shaft and can transport the oil after dipping the oil to the oil guiding channel, and is guided through the oil guiding channel to the bearing of the gearbox and used for lubricating the bearing. Due to the addition of the oil throwing member, compared with the previous method of only relying on the rotation of the gear to carry oil, the oil collection amount is more, the oil collection ability is stronger, the lubricating oil amount is more sufficient, and the lubrication effect is better. Especially under low-speed working conditions, the reliability of the working lubrication of the gearbox bearing can be greatly improved. In addition, compared with the forced oil supply lubrication for improving the lubrication effect, no additional lubricating oil pump is required, the structure is simple, and the manufacturing cost is low.
[0004] However, when this lubrication device is in use, since the size of the oil guiding channel in the oil collecting component cannot be adjusted, this device cannot meet the use of oil fluids with different viscosities. Specifically, when using an oil fluid with a higher viscosity, it will cause an increase in the flow resistance of the oil fluid in the oil guiding channel, affecting the lubrication effect; while when using an oil fluid with a lower viscosity, due to the decrease in the flow resistance of the oil fluid in the oil guiding channel, there will be a problem that the oil fluid is easily splashed and lost. To solve the above problems, a transmission device and a chemical pump are proposed in the present invention. Summary of the Invention
[0005] To achieve the above object, the present invention provides a transmission device, including a transmission body, and a lubricating pipe communicated with the transmission body. A guiding oil pipe is arranged in the lubricating pipe. The guiding oil pipe includes a first half-channel and a second half-channel which are separated from each other. One side of the first half-channel and the second half-channel close to each other forms an oil guiding channel. An elastic leak-proof cloth is arranged between the first half-channel and the second half-channel. The elastic leak-proof cloth is used for the sealed connection of the first half-channel and the second half-channel. The transmission device further includes a driving mechanism, and the driving mechanism is used to drive the second half-channel to move closer to or away from the first half-channel to change the size of the oil guiding channel.
[0006] Optionally, the oil guiding pipe further includes a first guiding and supporting assembly disposed between the first half-channel and the second half-channel and used for connecting the first half-channel and the second half-channel. The first guiding and supporting assembly includes a first guiding support rod, a first guiding support cylinder, and a first guiding support spring. The first guiding support rod is movably inserted into the first guiding support cylinder, and the first guiding support spring is wound around the first guiding support rod.

The vertical plate is fixedly connected to a side wall of the second half-channel.
[0008] Optionally, a plurality of resistance increasing mechanisms are arranged on both the first half-channel and the second half-channel. When the first half-channel and the second half-channel move closer to each other, a part of the resistance increasing mechanism will enter the oil guiding channel to increase the resistance of the moving lubricating oil in the oil guiding channel. The resistance increasing mechanism includes a moving hole opened on the first half-channel and a resistance increasing rod assembly movably arranged in the moving hole. One end of the resistance increasing rod assembly is sunken in the moving hole, and the other end of the resistance increasing rod assembly is fixedly connected to a supporting plate.

[0010] Optionally, the resistance increasing rod assembly includes a fixed seat fixedly connected to the supporting plate. An elastic cover is fixedly connected to the side wall of the fixed seat. A plurality of abutting balls are abutted on the inner side wall of the elastic cover. An abutting rod is rotatably arranged on the abutting ball, and the free end of the abutting rod is fixedly connected to the fixed seat. Wherein, the abutting ball abuts against the elastic cover and is slidably connected to the side wall of the moving hole.

[0011] Optionally, it further includes a magnet plate fixedly connected to the outer side wall of the elastic cover. The magnet plate is movably arranged in the moving hole. An arc-shaped groove is formed in the magnet plate. The resistance increasing mechanisms arranged on the first half-channel and the second half-channel are arranged oppositely, and the sides of the magnet plates in the two oppositely arranged resistance increasing mechanisms that are close to each other have opposite polarities, so that there is an attractive force between the two magnet plates.

[0014] To achieve the above object, the present invention provides a chemical pump, which includes a housing and the transmission device arranged in the housing.
[0015] The beneficial effects of the present invention are as follows: The present invention can adapt to oil fluids with different viscosities and improve the lubrication effect: The present invention drives the second half-channel to move closer to or away from the first half-channel through a driving mechanism, thereby changing the size of the oil guiding channel. This adjustable oil guiding channel design can be flexibly adjusted according to the viscosity of the oil fluid. When using an oil fluid with a higher viscosity, the size of the oil guiding channel can be increased to reduce the flow resistance of the oil fluid, ensure the smooth flow of the oil fluid, and avoid affecting the lubrication effect due to excessive resistance; when using an oil fluid with a lower viscosity, the size of the oil guiding channel can be reduced to increase the flow resistance of the oil fluid, prevent the oil fluid from splashing and dispersing, ensure that the lubricating oil can stably and evenly flow to the lubrication part, effectively improve the lubrication effect, and improve the operation stability and reliability of the chemical pump.
[0016] The present invention can enhance the structural stability and sealing performance: An elastic leak-proof cloth is provided between the first half-channel and the second half-channel for sealed connection, effectively preventing the leakage of lubricating oil and ensuring the normal operation of the lubrication system. At the same time, the oil guiding pipe further includes a first guiding and supporting assembly, which is composed of a first guiding support rod, a first guiding support cylinder and a first guiding support spring. This structural design can play a guiding and supporting role in the relative movement of the first half-channel and the second half-channel, ensure the smoothness of the movement, and avoid structural damage or sealing failure caused by shaking or deviation during the movement process, enhancing the structural stability and reliability of the entire transmission device.
[0017] The present invention can effectively control the flow resistance of the oil fluid and improve the lubrication efficiency: Resistance increasing mechanisms are provided on both the first half-channel and the second half-channel. When the first half-channel and the second half-channel move closer, a part of the resistance increasing mechanism will enter the oil guiding channel, thereby increasing the resistance of the moving lubricating oil in the oil guiding channel. This design can accurately control the flow resistance of the oil fluid as needed, further optimize the flow state of the lubricating oil, enable the lubricating oil to flow to the lubrication part at an appropriate speed and pressure in the oil guiding channel, improve the lubrication efficiency, reduce problems such as insufficient lubrication or over-lubrication caused by too fast or too slow flow of the oil fluid, and extend the service life of the chemical pump.
[0018] The present invention can achieve automatic pressurization and ensure the normal operation of the lubrication system: The transmission device further includes a pressurization mechanism. When the first half-channel and the second half-channel move away from each other beyond a preset threshold, the conduction component makes the circuit connected, the supercharger is powered on and starts, and pressurizes the oil guiding channel through the pressure guiding pipe. This automatic pressurization function can timely supplement the oil fluid pressure when the size of the oil guiding channel changes greatly, ensure that the lubricating oil can be continuously and stably supplied to the lubrication part, and ensure the normal operation of the lubrication system even under complex working conditions, further improving the reliability and stability of the chemical pump.
[0019] The structure of the present invention is simple, easy to maintain and manufacture: The transmission device of the present invention has a reasonable structural design, and the connection and cooperation methods between components are simple and clear, facilitating manufacturing and assembly. At the same time, due to its relatively compact structure and small occupied space, it can better adapt to the internal space layout of the chemical pump. In addition, the maintenance of the transmission device is also relatively convenient, and the replacement and repair operations of each component are simple, reducing the maintenance cost and time, and improving the economic efficiency of the chemical pump.

[0038] Structure and working principle of the resistance-increasing mechanism: The resistance-increasing mechanism 5 includes a moving hole 51 opened on the first half-channel 31 and a resistance-increasing rod assembly 52 movably arranged in the moving hole 51 (as Figure 4 and Figure 5 shown). One end of the resistance-increasing rod assembly 52 is sunk in the moving hole 51, and the other end is fixedly connected with a supporting plate 53 (as Figure 5 shown). When the first half-channel 31 and the second half-channel 32 move closer, a part of the resistance-increasing rod assembly 52 will enter the oil guiding channel, thereby increasing the resistance of the moving lubricating oil in the oil guiding channel.
[0039] Specifically, the structure of the resistance-increasing rod assembly 52 is as follows: Fixed seat 525: fixedly connected to the supporting plate 53 (as Figure 6 shown), providing support for the entire resistance-increasing rod assembly.
[0040] Elastic cover 521: fixedly connected to the side wall of the fixed seat 525 (as Figure 6 shown), having a certain elasticity and being able to adapt to the shape change of the channel when the resistance-increasing rod assembly 52 enters the oil guiding channel.
[0041] Contact ball 522: arranged on the inner side wall of the elastic cover 521 (as Figure 6 shown), slidingly connected to the side wall of the moving hole 51. A contact rod 523 is rotatably arranged on the contact ball 522, and the free end of the contact rod 523 is fixedly connected to the fixed seat 525 (as Figure 6 shown). This structural design enables the resistance-increasing rod assembly 52 to maintain stability during movement and to make self-adaptive adjustments according to the size change of the oil guiding channel.
[0042] Contact spring 524: connected between the side wall of the contact rod 523 and the fixed seat 525 (as Figure 6As shown, it provides elastic support to ensure that the contact ball 522 always maintains good contact with the side wall of the moving hole 51.
[0043] The action mechanism of the resistance increasing mechanism 5 is as follows: When the first half-channel 31 and the second half-channel 32 move closer, the resistance increasing rod assembly 52 gradually enters the oil guiding channel under the action of the elastic cover 521 and the contact spring 524. At this time, a part of the resistance increasing rod assembly 52 will contact the lubricating oil, thereby increasing the flow resistance of the lubricating oil in the oil guiding channel.
[0044] By adjusting the relative positions of the first half-channel 31 and the second half-channel 32, the depth of the resistance increasing rod assembly 52 entering the oil guiding channel can be controlled, and thus the precise adjustment of the flow resistance of the lubricating oil can be achieved.
[0045] The application scenarios of the resistance increasing mechanism 5 are mainly divided into the following two types: When the viscosity of the lubricating oil is low: When using lubricating oil with a low viscosity, the flow resistance of the lubricating oil in the oil guiding channel is small, and problems such as splashing or loss of the lubricating oil are likely to occur. At this time, by driving the mechanism 4 to make the first half-channel 31 and the second half-channel 32 closer, the resistance increasing rod assembly 52 of the resistance increasing mechanism 5 enters the oil guiding channel, increasing the flow resistance of the lubricating oil, thereby preventing the splashing or loss of the lubricating oil and ensuring that the lubricating oil can flow stably and evenly to the lubricating parts. For example, under the low-speed operating conditions of a chemical pump, the viscosity of the lubricating oil is low, and the resistance increasing mechanism 5 can effectively increase the flow resistance of the lubricating oil and ensure the normal operation of the lubrication system.
[0046] When the viscosity of the lubricating oil is high: When using lubricating oil with a high viscosity, the flow resistance of the lubricating oil in the oil guiding channel is already large. At this time, there is no need for the resistance increasing mechanism 5 to further increase the resistance. By driving the mechanism 4 to make the first half-channel 31 and the second half-channel 32 move away, the resistance increasing rod assembly 52 of the resistance increasing mechanism 5 exits the oil guiding channel, reducing the obstruction to the flow of the lubricating oil and ensuring that the lubricating oil can flow smoothly to the lubricating parts. For example, under the high-speed operating conditions of a chemical pump, the viscosity of the lubricating oil is high, and the withdrawal of the resistance increasing mechanism 5 can avoid the poor flow of the lubricating oil caused by excessive resistance, thereby improving the operating efficiency of the lubrication system.
[0047] It should be noted that the working principle of the resistance increasing rod assembly 52 in the present invention is as follows: The design purpose of the resistance increasing rod assembly 52 is to physically adjust the flow resistance of the lubricating oil in the oil guiding channel. Especially when the viscosity of the lubricating oil is low, the resistance is increased through a specific structural design to ensure the stable flow of the lubricating oil, and the lower the viscosity of the lubricating oil, the greater the resistance. The following is its detailed working principle: 1. Structural composition and function: Fixed seat 525: fixedly connected to the supporting plate 53, providing support for the entire resistance increasing rod assembly.
[0048] Elastic cover 521: fixedly connected to the side wall of the fixed seat 525, having certain elasticity. The main function of the elastic cover 521 is to adapt to the shape of the channel through its own elastic deformation when entering the oil guiding channel, and increase the contact area with the lubricating oil.
[0049] Contact ball 522: arranged on the inner side wall of the elastic cover 521, and slidably connected to the side wall of the moving hole 51. The function of the contact ball 522 is to provide stable support through contact with the side wall of the moving hole 51, and maintain good contact with the side wall through the elastic action of the contact spring 524.
[0050] Contact rod 523: rotatably arranged on the contact ball 522, and its free end is fixedly connected to the fixed seat 525. The function of the contact rod 523 is to connect the contact ball 522 and the fixed seat 525 to ensure the stability of the entire structure.
[0051] Contact spring 524: connected between the side wall of the contact rod 523 and the fixed seat 525, providing elastic support. The function of the contact spring 524 is to ensure that the contact ball 522 always maintains good contact with the side wall of the moving hole 51, and at the same time provide certain elastic buffering.
[0052] 2. Working mechanism when the viscosity of the lubricating oil is low: When the viscosity of the lubricating oil is low, the flow resistance of the lubricating oil in the oil guiding channel is small, and problems such as splashing or loss of the lubricating oil are likely to occur. At this time, the first half channel 31 and the second half channel 32 are brought closer by the driving mechanism 4, and the depth of the resistance increasing rod assembly 52 entering the oil guiding channel increases, thereby increasing the flow resistance of the lubricating oil. It should be noted that the two resistance increasing rod assemblies 52 on the opposite sides of the first half channel 31 and the second half channel 32 are attracted to each other by two magnet plates 6 and extend out of the moving hole 51. The specific mechanism is as follows: Insertion of the elastic cover 521: When the first half channel 31 and the second half channel 32 are brought closer, the elastic cover 521 gradually extends into the oil guiding channel under the mutual attraction of the two magnet plates 6. Since the elastic cover 521 has elasticity, it will undergo elastic deformation when entering the oil guiding channel, and with the pulling of the contact spring 524, the contact between the moving hole 51 and the contact ball 522 and the contact rod 523 disappears, which will cause the contact rod 523 to deflect upward or downward, and thus through the contact of the contact ball 522, the area of the elastic cover 521 increases, thereby increasing the contact area with the lubricating oil.
[0053] The penetration depth of the elastic cover 521 is related to the relative positions of the first half-channel 31 and the second half-channel 32. When they are closer to each other, the length of the elastic cover 521 extending into the oil guiding channel is longer, and the area of the elastic cover 521 is larger, thus further increasing the contact area with the lubricating oil.
[0054] Function of the abutting ball 522: The abutting ball 522 slides on the inner side wall of the elastic cover 521. Through the elastic action of the abutting spring 524, it always maintains good contact with the side wall of the moving hole 51. This contact not only provides stable support but also enables the elastic cover 521 to better adapt to the shape of the channel when entering the oil guiding channel through the sliding of the abutting ball 522. It can be understood that during the movement of the resistance increasing rod assembly 52 into the oil guiding channel, the elastic cover 521 gradually expands.
[0055] The abutting action of the abutting ball 522 enables the elastic cover 521 to be evenly distributed in the channel when entering the oil guiding channel, thereby increasing the contact area with the lubricating oil and further increasing the resistance.
[0056] Increase in resistance: When the viscosity of the lubricating oil is low, the flow resistance of the lubricating oil in the oil guiding channel is small. At this time, the penetration of the elastic cover 521 and the abutting action of the abutting ball 522 cause the lubricating oil to overcome greater resistance when passing through the oil guiding channel. The elastic deformation of the elastic cover 521 and the abutting action of the abutting ball 522 act together on the lubricating oil, slowing down the flow speed of the lubricating oil, thereby preventing the lubricating oil from splashing or dispersing and ensuring that the lubricating oil can stably and evenly flow to the lubricating parts. 3. Specific implementation method: In practical applications, the setting of the resistance increasing rod assembly 52 can automatically adjust the resistance according to the viscosity of the lubricating oil. The specific implementation method is as follows: Install the resistance increasing rod assembly 52: A moving hole 51 is opened on the first half-channel 31, and the resistance increasing rod assembly 52 is movably arranged in the moving hole 51. One end of the resistance increasing rod assembly 52 is sunken in the moving hole 51, and the other end is fixedly connected to the supporting plate 53.
[0058] A leak-proof plate 55 is movably sleeved outside the resistance increasing rod assembly 52, and the leak-proof plate 55 is fixedly arranged on the side wall of the first half-channel 31 to prevent the lubricating oil from leaking from the gap between the resistance increasing rod assembly 52 and the moving hole 51.
[0059] Adjust the resistance: When the viscosity of the lubricating oil is low, the driving mechanism 4 is used to move the first half-channel 31 and the second half-channel 32 closer, and the elastic cover 521 of the resistance increasing rod assembly 52 gradually extends into the oil guiding channel. Under the abutting action of the abutting ball 522, the elastic cover 521 undergoes elastic deformation, increasing the contact area with the lubricating oil, thereby increasing the flow resistance of the lubricating oil.
[0060] When the viscosity of the lubricating oil is high, the driving mechanism 4 is used to move the first half-channel 31 and the second half-channel 32 apart, and the elastic cover 521 of the resistance increasing rod assembly 52 withdraws from the oil guiding channel, reducing the obstruction to the flow of the lubricating oil and ensuring that the lubricating oil can smoothly flow to the lubrication part.
[0061] Furthermore, a magnet plate 6 is fixedly connected to the outer side wall of the elastic cover 521 (as shown in Figure 5 ), and the magnet plate 6 is movably arranged in the moving hole 51 (as shown in Figure 5 ). An arc-shaped groove 7 is formed in the magnet plate 6 (as shown in Figure 5 ), and the shape and size of the arc-shaped groove 7 should match the shape of the magnet plate 6 to ensure that the magnet plate 6 can smoothly move in the moving hole 51. The resistance increasing mechanisms 5 provided on the first half-channel 31 and the second half-channel 32 are arranged oppositely (as shown in Figure 4 ), and the sides of the magnet plates 6 in the two oppositely arranged resistance increasing mechanisms 5 that are close to each other have opposite polarities (as shown in Figure 4 ), so that there is an attractive force between the two magnet plates 6. This magnetic design can further enhance the stability of the resistance increasing mechanism 5 and assist it to enter the oil guiding channel to a certain extent.
[0062] Installation of the pressure increasing mechanism: Install the pressure increasing mechanism 8 for timely supplementing the oil pressure when the size of the oil guiding channel changes greatly (as shown in Figure 7 ).
[0063] Fix the supercharger 81 to the side wall of the second half-channel 32 (as shown in Figure 7 ), and the supercharger 81 can be connected to the second half-channel 32 by bolts or other fixing methods.
[0064] A pressure guiding pipe 82 is fixedly inserted on the supercharger 81 (as shown in Figure 7 ), and the pressure guiding pipe 82 is fixedly inserted on the second half-channel 32 (as shown in Figure 7 ), and the pressure guiding pipe 82 is used to connect the oil guiding channel with the boosting end of the supercharger 81.
[0065] Install the conduction assembly 83. The conduction assembly 83 includes a transverse plate 831 fixedly connected to the arc-shaped fixing plate 44 (as shown in Figure 7 ), and a vertical plate 832 is fixedly connected to the upper end surface of the transverse plate 831 (as shown in Figure 7As shown, a first conductive plate 833 is fixedly connected to the side wall of the vertical plate 832 (as Figure 7 shown), and a second conductive plate 834 is fixedly connected to the side wall of the second half-channel 32 (as Figure 7 shown). The second conductive plate 834 and the first conductive plate 833 are arranged to match each other (as Figure 7 shown). When the first half-channel 31 and the second half-channel 32 move away from each other beyond a preset threshold, the first conductive plate 833 contacts the second conductive plate 834, making the circuit connected, and the supercharger 81 is powered on and started to pressurize the oil guiding channel through the pressure guiding pipe 82.
[0066] Operation of the transmission device: Adjusting the size of the oil guiding channel: When the chemical pump is operating, according to the viscosity of the lubricating oil used, by controlling the telescopic movement of the driving cylinder 41 (the start of the driving cylinder 41 can be automatically controlled by a detector), the second half-channel 32 is driven to move closer to or away from the first half-channel 31 (as Figure 1 shown), thereby adjusting the size of the oil guiding channel. For example, when using an oil with a higher viscosity, the second half-channel 32 is pushed away from the first half-channel 31 by the driving cylinder 41 to increase the size of the oil guiding channel and reduce the resistance of the oil.
[0067] The setting of the pressurizing mechanism 8 can cooperate with increasing the size of the oil guiding channel, enabling the lubricating oil with a larger viscosity to smoothly enter the transmission body 1.

However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention. Moreover, the present invention described herein can have other embodiments and can be implemented or realized in various ways.
