[0005] In order to solve the above problems, the present application provides a rainwater collection and purification device, which adopts the following technical solutions:

[0006] A rainwater collection and purification device comprises a base, a purification cylinder is provided above the base, a supporting assembly is provided between the purification cylinder and the base, a sealing cover is provided on the top of the purification cylinder, a collecting bucket is fixedly installed on the top of the sealing cover, and a filter screen is provided in the collecting bucket, mounting blocks are fixedly installed on both sides of the collecting bucket, and a sealing assembly is provided between the two mounting blocks, a mounting rod is provided in the purification cylinder, and connecting rods distributed in a ring array are installed between the mounting rod and the inner wall of the bottom end of the sealing cover, four mounting rings distributed in a linear array are fixedly installed on the side wall of the mounting rod, and the side walls of the four mounting rings are sequentially sleeved with a filter screen bucket, a filter plate, an activated carbon plate and a bamboo fiber board from top to bottom, a fixing assembly is provided between the filter screen bucket, the filter plate, the activated carbon plate and the bamboo fiber board and the mounting rings of the same group, and a drain pipe is fixedly installed on the bottom end of the purification cylinder.

[0007] By adopting the above technical scheme, when the equipment is used, the staff installs the equipment outdoors. When it is raining, the sealing component is operated to open the collection bucket port, so that rainwater can enter the purification cylinder through the collection bucket, and the setting of the filter net in the collection bucket plays a role of preliminary filtering of rainwater. After the rainwater enters the purification cylinder, the rainwater passes through the filter sieve bucket, the filter plate, the activated carbon board and the bamboo fiber board in turn, so as to achieve the effect of further filtering and purifying the rainwater. The activated carbon board and the bamboo fiber board can play a role in removing foreign particles and bacteria in the rainwater. The filter sieve bucket, the filter plate, the activated carbon board and the bamboo fiber board are all fixedly installed on the side wall of the mounting rod through the fixing component, which is convenient for the staff to disassemble and replace later, and thus is conducive to maintaining the filtering effect of the equipment. The setting of the support component between the purification cylinder and the base plays a role of supporting and stabilizing the purification cylinder, which is conducive to maintaining the stability of the use of the purification cylinder. The filtered water source is discharged through the drain pipe. When it is sunny, the top of the collection bucket can be blocked by the sealing component, which helps to prevent dust and garbage from falling into the filter net, which is conducive to maintaining the cleanliness of the filter net, and is convenient for the equipment to be quickly put into use later.

[0008] Furthermore, the support assembly includes a support ring fixedly mounted on the side wall of the purification cylinder, and support rods distributed in a circular array are fixedly installed on the bottom end of the support ring, and the bottom ends of the support rods are fixedly connected to the top end of the base.

[0009] By adopting the above technical solution, the purification cartridge and the base cooperate with each other through the support ring and the support rod, which plays a role in supporting and stabilizing the purification cartridge, and is conducive to maintaining the stability of the purification cartridge when used.

[0010] Furthermore, the sealing assembly includes a sealing plate slidably installed between two mounting blocks, a discharge port opened on one side of the top of the collecting bucket, a second cylinder fixedly installed on the side of the collecting bucket away from the discharge port, a connecting plate fixedly installed on the side of the sealing plate away from the discharge port, the end of the piston shaft of the second cylinder is fixedly connected to the side opposite to the connecting plate, a sliding groove matching the sealing plate is opened on the opposite sides of the two mounting blocks, and a brush plate is fixedly installed on the bottom of the sealing plate near one end of the discharge port.

[0011] By adopting the above technical scheme, the second cylinder drives the connecting plate with the sealing plate to slide between the two mounting blocks, so that the sealing plate slides at the port of the collecting bucket, thereby blocking the collecting bucket. This helps to prevent dust and garbage from falling onto the filter installed in the collecting bucket when the equipment is not in use, thereby preventing the filter from being blocked. When the sealing plate slides at the top of the collecting bucket, the sealing plate slides with the brush plate on the filter, thereby cleaning the garbage on the filter. The garbage is discharged through the discharge port opened on one side of the collecting bucket. The staff can place the existing collecting device on the base to achieve the effect of receiving garbage. When it rains, the second cylinder drives the sealing plate away from the collecting bucket, thereby facilitating rainwater to enter the purification cylinder through the collecting bucket, thereby collecting rainwater.

[0012] Furthermore, the fixing assembly includes a retaining ring arranged at the bottom of the filter screen bucket, filter plate, activated carbon plate and bamboo fiberboard, and the bottom end of the retaining ring is provided with bolt ends distributed in a circular array and passing through the retaining rings in the same group, and the bottom end of the mounting ring is provided with a screw groove matching the bolts in the same group.

[0013] By adopting the above technical scheme, the staff will sequentially sleeve the filter sieve, filter plate, activated carbon board and bamboo fiberboard on the side wall of the mounting rod. The bottom of the filter sieve, filter plate, activated carbon board and bamboo fiberboard are provided with a retaining ring. The retaining ring is made of rubber and has elasticity, which is convenient for the staff to bend and pass through the mounting ring located at the lower section of the mounting rod, so that the staff can install the filter sieve, filter plate, activated carbon board and bamboo fiberboard. After the filter sieve, filter plate, activated carbon board and bamboo fiberboard are placed, the top of the retaining ring is fitted with the bottom of the mounting ring of the same group, and then the bolt is passed through the retaining ring of the same group, so that the bolt is screwed into the screw groove opened at the bottom of the mounting ring of the same group, which can play the role of fixing the filter sieve, filter plate, activated carbon board and bamboo fiberboard, and is convenient for the staff to disassemble and replace later, which is beneficial to maintain the filtering effect of the equipment.

[0014] Furthermore, positioning rods distributed in a ring array are fixedly mounted on the top of the retaining ring, and positioning holes matching with the positioning rods in the same group are opened at the bottom of the mounting ring.

[0015] By adopting the above technical solution, the top of the retaining ring plays a role in positioning and fixing the retaining ring and the mounting ring through the setting of the positioning rod, which is convenient for the staff to install later.

[0016] Furthermore, two symmetrically distributed blocks are fixedly mounted on both sides of the filter screen, and a card slot matching the card block on the same side is formed on the inner wall of the collecting bucket.

[0017] By adopting the above technical solution, the filter net is fixed by engaging the clamping block with the clamping groove provided on the inner wall of the collecting bucket. The cooperation between the clamping block and the clamping groove is conducive to maintaining the stability of the placement of the filter net and is convenient for the staff to disassemble and clean it later.

[0018] Furthermore, two symmetrically distributed stabilizing rods are fixedly installed between the bottom end of the collecting bucket and the top end of the sealing cover, and two symmetrically distributed first cylinders are fixedly installed at the bottom end of the base, and the ends of the piston shafts of the two first cylinders are fixedly connected to the side opposite to the collecting bucket.

[0019] By adopting the above technical scheme, when it is necessary to disassemble the filter sieve bucket, filter plate, activated carbon board and bamboo fiber board, the first cylinder drives the collecting bucket and the sealing cover to rise synchronously, and the sealing cover rises synchronously with the mounting rod, the filter sieve bucket, filter plate, activated carbon board and bamboo fiber board, so that the filter sieve bucket, filter plate, activated carbon board and bamboo fiber board are separated from the purification cylinder, which makes it convenient for the staff to disassemble and replace the filter sieve bucket, filter plate, activated carbon board and bamboo fiber board.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] (1) In the present application, by setting up the sealing assembly, the sealing plate is driven by the second cylinder to move on the top of the collecting bucket, thereby blocking the collecting bucket, which helps to prevent dust or garbage from falling onto the filter when the equipment is not in use. The sealing plate moves with the brush plate on the filter, which can clean the garbage on the surface of the filter, which is beneficial to maintain the cleanliness of the filter surface and facilitates subsequent reuse.

[0022] (2) In the present application, the filter sieve bucket, filter plate, activated carbon plate and bamboo fiberboard are all installed on the mounting rod through a fixing assembly. The staff can use the first cylinder to drive the collecting bucket to synchronously rise with the sealing cover, filter sieve bucket, filter plate, activated carbon plate and bamboo fiberboard, so that the filter sieve bucket, filter plate, activated carbon plate and bamboo fiberboard are separated from the purification cylinder, which is convenient for the staff to disassemble and replace, and is beneficial to maintaining the filtering and purification effect of the equipment.
