Description

  The present invention relates to a connection structure of a hand pump device connected to an existing electric pump or the like.

  Small electric pumps or hand pumps are used to pump water from household wells and tanks.

  For example, a hand pump is provided with a piston for sucking up water inside a cylinder having one end as a suction side and the other end as a discharge side, and this piston reciprocates via a piston rod. The structure which assembled | attached is used (for example, refer patent document 1). Such a hand pump is being reconsidered as a response to a power outage (disaster) due to recent heightened awareness of disaster prevention.

  For this reason, it is conceivable to install an electric pump and a hand pump in a well or the like in advance.

JP 2007-64105 A

  The hand pump described above has the following problems. That is, since an electric pump is normally attached to a household well or the like, a separate well is required to provide a hand pump, and an extra space must be secured. On the other hand, when an electric pump is removed and a hand pump is attached in an emergency, the hand pump must be attached to each shape of a well or the like, and a quick response is difficult. Also, once the hand pump is installed, it takes time to return it to the electric pump.

  Then, this invention aims at providing the connection structure of the hand pump for attaching a hand pump easily to a well, a tank, etc. in which the existing pump is installed.

  In order to solve the problems and achieve the object, the connection structure of the hand pump of the present invention is configured as follows.

(1) A stand erected on the ground, a hand pump attached to the stand, a connection pipe having one end connected to the suction port of the hand pump and the other end connected to a discharge port of another pump And a gate valve provided in the middle of the connecting pipe.

(2) In the connection structure of the hand pump described in (1), the gantry includes a gantry body formed in a columnar shape.

(3) In the connection structure of the hand pump described in (1), the mount is provided with a mounting plate for fastening with a bolt hole provided in a flange of the hand pump.

(4) A stand that stands on the ground, a hand pump attached to the stand, and a connection pipe having one end connected to the suction pipe of the hand pump and the other end connected to the water tank. It is characterized by.

  According to the present invention, it is possible to easily attach a hand pump to a well or a tank where an existing pump is installed.

Explanatory drawing which shows typically the hand pump and electric pump which were connected by the connection structure of the hand pump which concerns on one embodiment of this invention. The side view which shows the hand pump and electric pump which were connected by the connection structure of the same hand pump by notching partially. The front view which shows the principal part of the mount frame by the connection structure of the hand pump.

  FIG. 1 is an explanatory view schematically showing a hand pump 20 and an electric pump 50 connected by a hand pump connection structure according to an embodiment of the present invention, and FIG. 2 is a hand press connected by a hand pump connection structure. FIG. 3 is a side view showing the pump 20 and the electric pump 50 with a part cut away, and FIG. In FIG. 1, H indicates a house.

  As shown in FIG. 1, the hand pump connection structure includes a base 10 standing on the ground, a hand pump 20 attached to the base 10, one end connected to the suction pipe of the hand pump 20, and the other end. Includes a connecting pipe 30 connected to a discharge pipe or a suction pipe of an electric pump (another pump) 50 to be described later, and a gate valve 40 provided in the middle of the connecting pipe 30. In FIG. 1, reference numeral 50 denotes an electric pump directly connected to a well or a water tank, which is permanently installed.

  The gantry 10 includes a gantry body 11 formed in a cylindrical shape by a plate material 11a, a mounting plate 12 attached to a ceiling portion of the gantry body 11, a hole provided in the center, and a support plate 13 attached to a bottom portion. And offers. In addition, as shown in FIG. 3, the notch part 11b is formed in the lower part of the board | plate material 11a of the mount frame main body 11. As shown in FIG. The upper portion of the cutout portion 11b is formed in a semicircular shape.

  The hand pump 20 includes a main body 21 in which a piston mechanism, a discharge chamber, a suction chamber, and the like are provided, a link mechanism portion 22 that operates the piston mechanism, and an operation lever 23 that operates the link mechanism 22. . A suction port 21a is provided at the lower part of the main body 21, and a discharge port 21b is provided at the side surface. A flange 24 is provided on the lower side surface of the main body 21, and a bolt hole 24 a is provided in the flange 24.

  The connection pipe 30 includes a first pipe part 31 having one end attached to the suction port 21a of the main body 21 and a second pipe part 32 attached to the other end of the first pipe part 31 via a gate valve 40. I have.

  The electric pump 50 includes a main casing 51, a pump mechanism 52 provided in the main casing 51, a suction port 53 attached to the pump mechanism 52, a communication hole 54 communicating with the suction port 53, a pump A discharge port 55 (see FIG. 1) attached to the mechanism 52 is provided. The suction port 53 is directly connected to a well or the like. The discharge port 55 is connected to an indoor water supply.

  Using the thus configured hand pump connection structure, the hand pump 20 is installed as follows. That is, the gantry body 11 is erected at a desired position on the ground. Next, the hand pump 20 is attached to the attachment plate 12 of the gantry body 11. At this time, the bolt hole 24a of the hand pump 20 is used as it is.

  Next, one end of the first pipe portion 31 is attached to the suction port 21 a of the hand pump 20 and pulled out of the gantry 11. At this time, since the notch 11b is rounded, safety can be ensured. Subsequently, the gate valve 40 is attached to the other end of the first pipe portion 31, and then one end of the second pipe portion 32 is attached. Then, the other end of the second pipe portion 32 is attached to the communication hole 54 of the electric pump 50.

  The hand pump 20 thus connected is used as follows. That is, the gate valve 40 is opened in an emergency such as a power failure. As a result, the suction port 21 a of the hand pump 20 communicates with the communication hole 54 of the electric pump 50 through the connection pipe 30. Since the communication hole 54 is connected to a well or the like through the suction port 53, the piston mechanism is operated by operating the operation lever 23, and water can be sucked into the main body 21. Then, water is discharged from the discharge port 21b.

  On the other hand, normally, by closing the gate valve 40 and operating the electric pump 50, water from a well or the like is sucked from the suction port 53 and discharged from the discharge port 55.

  As described above, according to the connection mechanism of the hand pump according to the present embodiment, even if another pump such as the electric pump 50 is already attached to the well or the like, it is separately provided for the hand pump 20. There is no need for a well or the like, and no extra space is required. Moreover, since the hand pump 20 can be attached by simple construction without removing the electric pump 50 in an emergency, a quick response was possible. Further, even when the hand pump 20 is connected, the electric pump 50 can be operated only by closing the gate valve 40 at normal times, so that handling is easy.

  On the other hand, since the gantry body 11 expected to be installed by the user is formed in a columnar shape and the notch portion 11a is also rounded, it can be safely constructed.

  The present invention is not limited to the above embodiment. For example, the connection pipe 30 is attached to the well via the communication hole 54 and the suction port 53 of the electric pump 50, but the connection pipe 30 may be directly inserted into the well or the water tank. Of course, various modifications can be made without departing from the scope of the present invention.

  It is possible to provide a hand pump connection structure for easily attaching a hand pump to a well or tank where an existing pump is installed.
